Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to and the benefit of U.S. Patent Application Serial No. 16/897,678, filed June 10, 2020, which is a continuation-in-part of U.S. Patent Application Serial No. 16/239,161, filed January 3, 2019, the disclosure of which is incorporated herein by reference in its entirety.

FIELD OF THE DISCLOSURE The present disclosure relates generally to a personal evaporative air cooler with a clip.

Background Personal evaporative air coolers are commonly used to cool air in homes, offices, or other hot, dry air environments. Traditional evaporative air coolers work by drawing ambient air into the evaporative air cooler and passing it through a water-submerged filter arrangement. As the warm air passes through the water-submerged filter, heat from the ambient air evaporates water trapped within the water-submerged filter arrangement. The evaporated water cools the air as it leaves the water-submerged filter arrangement and exits the evaporative air cooler.

A conventional evaporative air cooler typically includes a fan, a filter device, and a water distribution system. The fan draws outside air into the evaporative air cooler, passes it through the filter device to generate cooler air, and then pushes the cooler air out of the evaporative air cooler. More specifically, the water distribution system supplies water to the filter device so that the filter device is submerged in water. The water distribution system includes a water pump that draws water from a reservoir and distributes the water to the bottom surface of the filter device, which is submerged upward. Depending on the type of filter and the amount of water in the reservoir, the water travels only partially up the filter. If the filter is not fully submerged in water, the evaporative air cooler is less effective at generating cooler air. The filter device typically includes a filter made of a paper-like material that must be replaced frequently. The filter cannot be reused or easily cleaned.

Some of the water dispensed into the filter device evaporates as air flows through the filter. As the evaporative cooler works by evaporation, the water in the reservoir is depleted. Non-absorbed water that recirculates within the evaporative cooler returns to the reservoir. When the reservoir is completely depleted of water but the filter device is submerged in water, the evaporative cooler can still produce cooler air, but less effectively. The evaporative cooler stops producing cooler air when the filter device dries out. Therefore, additional water must constantly be added to replace the evaporated water.

Typically, a conventional evaporative air cooler takes a significant amount of time to start cooling the air because the filter device must suck water up from the reservoir before the cooling process can begin. In other words, a conventional evaporative air cooler does not instantly produce cooler air.

Furthermore, conventional evaporative air coolers are typically placed on a flat surface, such as a table, countertop, or desk, to cool an individual in the room. Conventional evaporative air coolers are not configured to be attached to an apparatus, such as the end of a shelf or a stroller handle.

DETAILED DESCRIPTION The following description is merely exemplary in nature and is not intended to limit the disclosure in its application or uses. For purposes of clarity, the same reference numbers are used in the description and drawings to identify like elements.

This disclosure generally relates to a personal evaporative air cooler that draws in ambient air, cools the ambient air, and blows out the cooled ambient air. In this disclosure, the personal evaporative air cooler may be referred to as an evaporative air cooler, a portable evaporative air cooler, or any other desired air cooler.

The evaporative air cooler 10 may include a housing 20 having a power adapter, a water tank 40, a V-shaped shroud 44, a fan 48, a drawer 50, and a filter structure 56.

FIG. 1 illustrates an exemplary evaporative air cooler 10. The evaporative air cooler may include a housing 20 having a top surface 22, a bottom surface 24, and four lateral sides, such as a front surface 26, a back surface 28, and a side surface 30. The housing 20 may be formed as a cubic housing, a rectangular housing, or any other desired configuration or shape. The housing 20 may be formed from plastic or any other desired material.

The top surface 22 can include a lid, such as a hinged lid 32. FIG. 2 shows the evaporative air cooler 10 with the hinged lid 32 open for access to the water tank 40. The hinged lid 32 can be located along the front of the top surface 22. The hinged lid 32 can include a lid tab 76 positioned in front of the hinged lid 32 or any other desired location. The hinged lid 32 can be opened to allow water to fill the water tank 40. For example, a user can pull the lid tab 76 upward to open the hinged lid 32. The hinged lid 32 can be formed from plastic or any other desired material. The opening to the water tank 40 can be any desired opening and is not limited to the hinged lid 32 described in this disclosure.

The top surface 22 may also include buttons, such as a power button 34, a light button 36, or any other desired button. The top surface 22 may also include one or more lights, such as an indicator light 38, or any other desired light or indicator. The indicator lights 38 may be used to indicate the fan speed, the level of water located in the water tank 40, whether the filter 58 should be changed, or any other desired indication. For example, at high speed, all three indicator lights 38 may be ON. At medium speed, two indicator lights 38 may be ON. At low speed, one indicator light 38 may be ON. In one embodiment, if the power button 34 is pressed for at least three seconds, all of the indicator lights 38 may be turned off. The indicator lights 38 may include one or more lights. The indicator lights 38 may display a flashing light or a continuous light. The indicator lights 38 may display different light colors, such as green, red, amber, or any other desired color.

The power button 34 can be configured to activate (e.g., power ON), change the fan speed of the fan 48, and stop operation of the evaporative air cooler 10 (e.g., power OFF). For example, when the power button 34 is activated once, the indicator lights 38 (e.g., the three indicator lights 38) can be turned on, the fan 48 can be turned on (e.g., to high speed), and an aperture 42 positioned within the water tank 40 can allow water to flow out of the tank 40 to begin the evaporative air cooling process. When the power button 34 is activated a second time, one of the indicator lights 38 can be turned OFF (e.g., the two indicator lights 38 remain ON), the fan speed can be reduced (e.g., to medium speed), and the aperture 42 can allow less water to flow out of the tank 40. When the power button 34 is activated a third time, one of the indicator lights 38 can be turned OFF (e.g., one indicator light 38 remains ON), the fan speed can be reduced (e.g., slow), and the aperture 42 can allow less water to flow out of the tank 40. When the power button 34 is activated a fourth time, one of the indicator lights 38 can be turned OFF (e.g., none of the indicator lights 38 remain ON), the fan 48 can be turned OFF, and the aperture 42 can stop water from flowing out of the tank 40. In other words, the power button 34 can be activated to deactivate or power off the evaporative air cooler 10. In one embodiment, when the power button 34 is activated (e.g., pressed downward) for more than three seconds, the indicator lights 38 and the evaporative air cooler 10 can be turned OFF.

The fan 48 may be hardwired to the evaporative air cooler 10. The wiring may be soldered to electrically connect the fan 48 to the evaporative air cooler 10, or may be attached in any other desired manner. The wiring may be hidden in a wiring compartment or any other desired compartment within the evaporative air cooler 10.

A light, such as a blue LED light, may be positioned within the water tank 40, such as under the power button 34, or any other desired area to illuminate the water tank 40. The light may be used for environmental, as a night light, or for any other desired purpose. When the evaporative air cooler 10 is powered on, the light may be on by default. The user can reduce the brightness of the light or turn the blue LED completely OFF by pressing the light button 36. For example, after the power button 34 is pressed, the light is in high brightness mode. When the user presses the light button 36 once, the light can reduce its brightness (e.g., to low brightness mode). When the user presses the light button a second time, the light can be turned OFF. In one embodiment, if the light button 36 is activated for a minimum amount of time (e.g., 3 seconds), a lighting setting can be selected and/or locked.

2, the bottom surface 24 may include legs 62 that protrude outwardly from the bottom surface 24. The legs 62 may be configured to lift the evaporative air cooler 10 off of the surface on which it is placed. The legs 62 may also be configured to prevent the evaporative air cooler 10 from damaging the surface. For example, the legs 62 may prevent the surface from being scratched as the evaporative air cooler 10 slides across the surface. The legs 62 may be formed from rubber, plastic, grip, or any other desired material. The bottom surface 24 may include a plurality of legs 62. The legs 62 may be formed as circular legs 62, oval legs 62, square legs 62, rectangular legs 62, or any other desired shape. The legs 62 may be positioned towards each corner of the bottom surface 24 or in any other desired location. In an alternative embodiment, the bottom surface 24 does not include the legs 62.

The lateral side can include a front surface 26, a back surface 28, and two side surfaces 30. The lateral side can be positioned between the top surface 22 and the bottom surface 24 around their perimeters. The lateral side can be positioned adjacent to one another. The lateral side can include a framed portion 64 and a face portion 66. The framed portion 64 can be positioned around the perimeter of the lateral side, and the face portion 66 is positioned within the framed portion 64. For example, the side 30 can include a top portion 68, a framed portion 64 adjacent the top portion 68 and positioned along the side and bottom edges of the side 30, and a face portion 66 positioned within the framed portion 64.

As shown in FIG. 3, the front surface 26 may include an upper portion 68 and a framed portion 64 adjacent the upper portion 68 and positioned along the side and bottom edges of the top surface 22. The front surface 26 may also include an outlet vent 52 positioned within the framed portion 64. The outlet vent 52 may include a plurality of vents 70, an air direction tab 72, and a filter pull tab 120. The plurality of vents 70 may include a fixed vent 122 and an adjustable vent 124. For example, the fixed vent 122 may be positioned as the lowest vent 70 on the outlet vent 52. The remainder of the plurality of vents 70 may consist of the adjustable vent 124. Each of the plurality of vents 70 may be positioned horizontally at the outlet vent 52. Each of the adjustable vents 124 may be movably connected to the air direction tab 72. The air direction tabs 72 can be positioned to direct air flowing from the interior of the evaporative air cooler 10 through the outlet vents 52. For example, if the air direction tabs 72 are positioned upward, the adjustable vents 124 can be positioned upward to direct the air flow upward. Similarly, if the air direction tabs 72 are positioned downward, the adjustable vents 124 can be positioned downward to direct the air flow downward. If the air direction tabs 72 are positioned in a center position, the adjustable vents 124 can be positioned in a substantially horizontal position, directing the air to flow horizontally from the evaporative air cooler 10. The air direction tabs 72 can direct the air to flow at any angle between a downward angle and an upward angle.

The face portion 66 of the front surface 26, such as the outlet vent 52, can be connected to an internal assembly 74 that is removable from the housing 20. As shown in Figs. 4 and 5, the internal assembly 74 of the evaporative air cooler 10 can include a filter structure 56 including a filter 58, a drawer 50 including a water tray 54. The internal assembly 74 can fit tightly around the periphery of the fan 48. For example, the internal assembly 74 can form a seal around the periphery of the fan 48 to direct air out of the evaporative air cooler 10. The internal assembly 74 can be configured to increase the force of the air as it exits the evaporative air cooler 10 to increase the cooling effect of the evaporative air cooler 10. The internal assembly 74 can also be configured to reduce noise generated during operation of the evaporative air cooler 10. For example, a seal such as an airtight seal reduces the amount of air that escapes the evaporative air cooler 10 and reduces air vibrations of other components or walls of the evaporative air cooler 10.

The drawer 50 can be attached to the outlet vent 52. The outlet vent 52 can be removed from the evaporative air cooler 10. For example, the fixed vent 122 can include a filter pull tab 120. A user can pull the filter pull tab 120 to remove the outlet vent 52 from the evaporative air cooler 10. The outlet vent 52 can have one or more tabs or any other desired device for removing the outlet vent 52 from the evaporative air cooler 10. The inside of the side 30 can include a drawer guide 108. The drawer guide 108 is configured to assist a user in slidably removing the drawer from the housing 20 and slidably inserting the drawer into the housing 20.

The drawer 50 can include a water tray 54. The water tray 54 can be positioned within the drawer 50. The water tray 54 can be formed as a bottom of the housing 20. The water tray 54 can be angled so that any liquid on the water tray 54 flows in a direction toward the filter structure 56. For example, the water tray 54 can be higher toward the rear end 78 of the drawer 50 than toward the front end 80 of the drawer. The water tray 54 can be configured for cleaning. For example, once the drawer 50 is removed from the evaporative air cooler 10 and the filter structure 56 is removed from the water tray 54, the water tray 54 is easily accessible for cleaning. A user can wipe, dry, or otherwise clean the water tray 54. Cleaning the water tray 54 can result in a reduction of mold or other bacteria.

The drawer 50 can be configured to support a filter structure 56. The filter structure 56 can be removably attached to the drawer 50. The drawer 50 can have a drawer notch 128 to secure the filter structure 56 in place. For example, the filter structure 56 can be positioned on the top surface of the water tray 54 between the outlet vent 52 and the drawer notch 128.

6A-6C, the filter structure 56 can include a filter frame 82 and a number of filter holders 84 attached to both sides of the filter frame 82. In an exemplary embodiment, as shown in FIG. 6C, the filter frame 82 can include a top opening 86 and a bottom opening 88. The top opening 86 can be configured to allow mist 118 to contact the top 112 of the filter 58. The bottom opening 88 can be configured to allow liquid, such as mist 118 and/or water, to contact the bottom 114 of the filter 58. For example, if liquid is collected in the water tray 54, the liquid can contact the bottom 114 of the filter 58. The sponge material 60 of the filter 58 can soak up the liquid. The sponge material 60 can also soak up the mist 118 as it contacts the filter 58. The filter holder 84 can define a number of holes or filter openings 90. Each filter opening 90 can be configured such that one filter 58 is positioned within the filter opening 90. The filter holders 84 can be positioned substantially parallel to one another within the filter structure 56. The filter holders 84 can be configured to hold the filters 58 in place. The filters 58 can be positioned substantially parallel to one another and to the sides of the filter structure 56. The filter holders 84 can be configured to have a space, such as a gap 92, between each filter holder 84 to allow the mist 118 and/or liquid to contact the filters 58. The air and/or mist 118 may also exit the evaporative air cooler 10 through the gap 92. The filter structure 56 can be formed from plastic, metal, or any other desired material.

4-6, the filter structure 56 can include multiple filters 58 mounted vertically. The filters 58 can be positioned parallel to the direction of airflow. The filters 58 can be formed from a sponge material 60. The filters 58 can be soaked before use. For example, a user can pull the filter pull-out tab 120 on the outlet vent 52 to pull out the inner assembly 74 including the drawer 50, water tray 54, and filter structure 56. The inner assembly 74 can slide out from within the evaporative air cooler 10. The filter structure 56 can be removed from the drawer 50. The filter structure 56 can be placed in a liquid such as water, can be placed under running water, or any other desired method for soaking the filters 58 can be used. After the filters 58 are wetted, the filter structure 56 can be placed in a freezer or any other desired cooling device. Freezing the wet filters 58 can increase the cooling effect of the evaporative air cooler 10. Once complete, the user can place the filter structure 56 onto the drawer 50 and slide the inner assembly 74 back into the evaporative air cooler 10. If the filter 58 is pre-wetted, when the evaporative air cooler 10 first begins to operate, the initial cooling effect may be increased as air moves through the wet filter 58. If the filter 58 is not pre-soaked, the evaporative air cooler 10 may generate cooled air, but it may not be at full capacity.

The filter structure 56 including the multiple filters 58 can be constructed of a sponge material 60, a plastic and sponge material 60, or any other desired material. The filter structure 56, along with the filters 58, can be configured for cleaning. For example, the plastic and sponge material 60 can be cleaned using various methods such as hand washing, soaking, dishwashing, or any other desired method. The filter structure 56 including the filters 58 can be sanitized. For example, the filter structure 56 including the filters 58 can be sanitized in a microwave or any other desired method. The filters 58 can be handled, washed, and used more vigorously than filters formed from paper materials. The filters 58 are reusable, can be used longer between being wetted, rewetted, and redried, and have an overall longer life and usefulness than paper filters. The filter structure 56 can be replaced, for example, after 3-6 months of use.

The evaporative air cooler 10 can also be powered on without water in the water tank 40 to dry out the filter 58 and the interior of the evaporative air cooler 10. For example, if a user plans to not use the evaporative air cooler 10 for an extended period of time, the user can empty the water tank 40 and press the power button 34 to turn the evaporative air cooler 10 on in high mode for, for example, four hours.

The back 28 can include a top 68 and a framed portion 64. The back 28 can include a power port for a power adapter. The power adapter includes a cord having a first power adapter plug at one end configured to plug into the power port and a second power adapter plug at an opposite end of the cord configured to plug into an outlet, such as a wall outlet or power strip. The power port can be located at the top 68 of the back 28 or any other desired location on the evaporative air cooler 10. In another embodiment, the evaporative air cooler 10 can be powered using a battery or another power source.

The back surface 28 may also include a grille 94. The grille 94 may be positioned within the framed portion 64. The grille 94 may include a number of ribs positioned horizontally or vertically along the back surface 28. As shown in FIGS. 5 and 6, the grille 94 includes both horizontal ribs 96 and vertical ribs 98 that define a number of grille openings 100. The number of grille openings 100 are configured to allow air to flow from the outside of the evaporative air cooler 10 to the inside of the evaporative air cooler 10. The grille 94 may also have a cord guide for securing the cord of the power adapter in place. The cord guide may be located along one side of the grille 94, adjacent to the framed portion 64, or in any other desired location. The grille 94 may have one or more cord guide tabs. Additionally, some of the horizontal ribs 96 may be shorter to allow the cord to be positioned flush with the horizontal ribs 96.

7 and 8, the fan cover assembly 102 can include the grate 94, the fan 48, and the fan cover 46. The fan cover assembly 102 can be configured to reduce vibrations and other motions within the evaporative air cooler 10. In this way, the fan cover assembly 102 can reduce the operating noise of the evaporative air cooler 10. The fan cover assembly 102 can also effectively direct airflow. For example, the fan cover assembly 102 can effectively direct air outwardly from the evaporative air cooler 10.

For example, the fan 48 can direct the airflow from the rear surface 28 towards the front surface 26. The fan 48 can be positioned within the housing 20 between the grille 94 and the fan cover 46. The fan cover 46 can be configured to further direct the airflow. For example, the fan cover 46 can provide an optimal airflow rate for the size and type of evaporative air cooler 10. The fan cover 46 can be configured to maximize the technical and electrical specifications of the fan 48.

The user may control the speed of the fan 48. For example, the user may press the power button 34 to toggle the fan speed between three different speeds (e.g., high, medium and low). Varying the fan speed may vary the water flow rate through the aperture 42. The change in water flow rate may be proportional to the change in fan speed. At high speed, the water flow rate may be high. At medium speed, the water flow rate may be medium. At low speed, the water flow rate may be low.

Thus, the misting structure 104 can be configured to generate various amounts of mist 118. The amount of mist 118 generated can be based on the fan speed. For example, as the fan speed increases, the amount of mist 118 can increase. The increased amount of mist 118 can allow an optimal amount of moisture to enter the air, resulting in a better cooling effect. As the fan speed decreases, the amount of mist can also decrease.

For example, when the power button 34 is pressed, the evaporative air cooler 10 can be turned on. The fan 48 can start spinning and the mist 118 can start spraying from the misting structure 104. The default fan speed can be high when the evaporative air cooler 10 is first powered on, or any other desired fan speed. The user can use the power button 34 to adjust the cooling effect of the evaporative air cooler 10, including the amount of mist 118 and/or the airflow speed. The user can adjust the direction of the airflow (e.g., from top to bottom) using the air direction tab 72 on the outlet vent 52. The power button 34 can be pressed again to turn off the evaporative air cooler 10.

As shown in FIG. 7, the V-shaped shroud 44 may be positioned under the top interior panel 110 to allow the liquid to convert to mist 118. The top interior panel 110 may be a wall between the evaporative air cooler 10 and the water tank 40, the bottom of the water tank 40, or any other desired structure. The V-shaped shroud 44 may be configured to distribute the mist 118 evenly toward the filter 58. The even distribution of the liquid on the filter 58 provides an effective cooling effect to the user. The V-shaped shroud 44 may be configured to maximize airflow to the user.

For example, the V-shaped shroud 44 can extend from the bottom of the water tank 40 into the evaporative air cooler 10. The fan 48 used with the V-shaped shroud 44 can turn the liquid into mist 118 and direct the mist 118 toward the filter structure 56 and the filter 58. Some of the mist 118 can evaporate, and some of the mist 118 can travel between the sponge material 60 and through the outlet vent 52 to cool the air outside the housing 20. Some of the mist 118 can soak into the sponge material 60, allowing for later evaporative cooling. Some of the mist 118 can fall into the water tray 54, where it can be collected and become liquid. The liquid can be absorbed into the filter 58 via capillary action, allowing for additional evaporative cooling. The water tray 54 can be configured with a slight angle. This slight angle can cause excess or non-absorbed liquid to flow toward the filter 58. The excess liquid is absorbed and wicked up by the filter 58, allowing for a longer cooling effect. Also, by siphoning excess water, it reduces water spillage when the evaporative air cooler 10 is moved or the drawer 50 is removed from the evaporative air cooler 10.

4 and 9, the housing 20 can include a container or tank, such as a water tank 40, positioned below the top surface 22. A liquid, such as water, can be placed in the water tank 40. For example, when the hinged lid 32 is open, the liquid can be poured into the water tank 40 using a water pitcher or any other desired means. The water tank 40 can have an opening, such as an aperture 42, for releasing the liquid from the water tank 40 into the evaporative air cooler 10. The aperture 42 can be positioned at the bottom of the water tank 40. The aperture 42 can be positioned between the V-shaped shroud 44 and the front surface 26. More specifically, the aperture 42 can be positioned between the V-shaped shroud 44 and the filter structure 56.

The evaporative air cooler 10 can use two-stage cooling in its cooling process. The first stage can incorporate an atomizing structure 104. The atomizing structure 104 can include a microporous atomizer, such as atomizer 106. The second stage can incorporate a filter structure 56 having an evaporative sponge filter, such as filter 58 made from sponge material 60. The combination of both stages can provide an immediate and long-term cooling effect.

The mist 106 can provide an immediate cooling effect. For example, when the evaporative air cooler 10 is powered on, the mist 118 begins spraying from the mist 106. The power of the fan 48 can be positioned behind the mist 118 to distribute the mist 118 into the ambient air or air and onto the filter 58. As the mist 106 operates for a sustained period of time, the filter 58 becomes wetter (e.g., a wet filter). Air that encounters the mist 118 can feel cooler to the user due to the evaporative cooling process. As air continues to pass through the wet filter 58, the cooling effect can be extended. When liquid is consumed from the water tank 40, the mist 118 can stop, but the filter 58 can remain wet for a period of time, allowing at least some evaporative cooling to continue.

The atomizing structure 104 may be located or partially located within the water tank 40. For example, the atomizer 106 may be assembled through the opening 42 of the water tank 40. The atomizing structure 104 may be attached to the bottom of the water tank 40, the top interior panel 110, or any other desired location using the atomizing structure attachment 126. The atomizing structure attachment 126 may include a screw inserted through a threaded hole, or any other desired attachment. The atomizer 106 may be positioned upside down within the top-fill water tank 40. The atomizer 106 may emit water downward into the interior of the evaporative air cooler 10. Liquid may be fed directly to the atomizer 106. The atomizer 106 may distribute the mist 118 (e.g., moisture) to the sponge filter. By atomizing the filter 58 from the top of the evaporative air cooler 10, the mist 118 may more effectively penetrate the filter 58. The atomizer 106 can provide an even distribution of mist 118 to the filter 58, including the top 112 of the filter 58. The walls of the water tank 40 can have an angle configured to allow an increased amount of liquid to reach the atomizer 106.

The atomizer 106 can be configured to restrict water flow from the opening 42 when the evaporative air cooler 10 is turned OFF.

The atomizing structure 104 may be wired to the evaporative air cooler 10. The wiring may be soldered or attached in any other desired manner to electrically connect the atomizing structure 104 to the evaporative air cooler 10. The wiring may be hidden in a wiring compartment or any other desired compartment within the evaporative air cooler 10.

The evaporative air cooler 10 can operate for a period of time. This period of time can depend on various factors, such as the amount of water in the water tank 40, whether the filter 58 is pre-soaked, whether the filter 58 is initially frozen, and the cooling mode selected based on the fan speed. In one embodiment, the evaporative air cooler 10 can operate for 8 hours in high mode, 10 hours in medium mode, and 12 hours in low mode without refilling the water tank 40.

The evaporative air cooler 10 may include additional and/or fewer components and is not limited to those shown in the figures.

In an exemplary embodiment, the evaporative air cooler 10 includes a water tank 40, an atomizing structure 104, a filter structure 56, and a fan 48. The water tank 40 can include a liquid inlet (e.g., via the hinged lid 32) and a liquid outlet (e.g., via the aperture 42). Liquid can enter the water tank 40 through the liquid inlet and exit the water tank through the liquid outlet. The atomizing structure 104 can be in liquid communication with the water tank 40. The atomizing structure 104 can be configured to generate a mist 118 as the liquid flows through the liquid outlet. The filter structure 56 can include a plurality of filters 58 positioned substantially parallel to one another and defining a gap 92 therebetween. The fan 48 can be configured to draw ambient air into the evaporative air cooler 10 and direct the ambient air out of the evaporative air cooler 10 through the filter structure. Thus, the ambient air can be cooled before exiting the evaporative air cooler 10.

The atomizing structure 104 can distribute the mist 118 into the ambient air and over the multiple filters 58. The atomizing structure 104 can include an atomizer 106. The atomizer 106 can be positioned adjacent to the water tank 40. The atomizer 106 can also be positioned within the water tank 40. Liquid can flow from the water tank 40 through the top of the atomizer 106 toward the bottom of the atomizer 106. The atomizer 106 can emit the mist 118 from the atomizing structure 104 into the ambient air in the evaporative air cooler 10. The mist 118 can cool the ambient air.

The misting structure 104 can generate a first amount of mist 118 when the fan 48 is at a first speed. The misting structure 104 can generate a second amount of mist 118 when the fan is at a second speed. The first amount can be greater than the second amount, and the first speed can be greater than the second speed. In other words, when the fan is at high, more mist 118 can be sprayed from the mister 106.

The evaporative air cooler 10 may include an internal assembly 74 configured to form a seal 116 with the fan 48. The seal 116 may allow ambient air to exit the evaporative air cooler 10 with greater force than it entered the evaporative air cooler 10. The internal assembly 74 may include at least one of a filter structure 56 and a drawer 50. The internal assembly 74 may be removably attached to the evaporative air cooler 10. The internal assembly 74 may include a drawer 50 attached to the outlet vent 52. The drawer 50 may include a water tray 54 angled toward the outlet vent 52. The filter structure 56 may be positioned adjacent to the outlet vent 52 on the water tray 54. Condensation or liquid in the drawer 50 may flow toward the outlet vent 52. The plurality of filters 58 may be formed from a sponge-like material, such as a sponge material 60. Thus, when the filter structure 56 is positioned adjacent to the outlet vent 52, the multiple filters 58 can wick up liquid as it flows toward the outlet vent 52. When the multiple filters 58 are at full liquid capacity, the sponge material 60 may not wick up additional liquid. The liquid in the filters 58 can be used to cool the ambient air. As the liquid in the filters 58 cools the ambient air, liquid may evaporate from the filters 58. The filters 58 may not be at full liquid capacity after evaporation has occurred, and therefore may wick up more liquid.

The filter structure 56 can be configured to be removed from the evaporative air cooler 10. The filter structure 56 and the plurality of filters 58 are washable and reusable. The plurality of filters 58 can be pre-soaked with liquid and inserted into the evaporative air cooler 10. Pre-soaking the filters 58 can extend the cooling of the evaporative air cooler 10.

The evaporative air cooler 10 may include a shroud, such as a V-shaped shroud 44 adjacent the underside of the water tank 40. The shroud may be V-shaped or any other desired shape.

In an exemplary embodiment, the portable evaporative air cooler 10 for cooling ambient air includes an atomizing structure 104, a filter structure 56, and a fan 48. The atomizing structure 104 can be configured to evaporate liquid within the portable evaporative air cooler 10. The filter structure 56 can include a plurality of filters 58 configured to absorb the liquid. The fan 48 can be configured to draw ambient air into the portable evaporative air cooler 10. The ambient air can be cooled by at least one of the mist 118 and the filter structure 56. The fan 48 can direct the ambient air out of the portable evaporative air cooler 10 through the filter structure 56.

The filters 58 may be formed from a sponge material 60 and positioned to define gaps, such as gaps 92, between the filters 58. The filters 58 may be removable from the portable evaporative air cooler 10. The filters 58 may be soaked in liquid prior to entering the portable evaporative air cooler 10.

The filter structure 56 can be positioned within the drawer 50. The drawer 50 can be removable from the portable evaporative air cooler 10. The portable evaporative air cooler 10 can include a forward grille such as an outlet vent 52, along with air direction tabs 72 for directing airflow and a filter pull tab 120 for pulling the drawer 50 from the portable evaporative air cooler 10.

In an exemplary embodiment, the personal air cooler 10 includes a housing 20, a tank, such as a water tank 40, an atomizing structure 104, a filter structure 56, and a v-shaped shroud 44. The housing includes a top panel (e.g., top surface 22), a bottom panel (e.g., bottom surface 24), and side panels (e.g., front surface 26, rear surface 28, and side surface 30) that can define an interior of the personal air cooler 10. The tank can be positioned adjacent to the top panel and at least one of the side panels and can be configured to receive, store, and discharge liquid. The atomizing structure 104 can be in fluid communication with the tank and configured to generate mist 118. The filter structure 56 can be adjacent to the bottom panel and at least one of the side panels. The v-shaped shroud 44 can be positioned below the tank and configured to direct the mist 118 toward the filter structure 56.

The personal air cooler 10 may include a fan 48 positioned adjacent one of the side panels. The personal air cooler 10 may also include a fan cover 46 adjacent the fan 48 and configured to direct air from the exterior of the personal air cooler 10 toward the v-shaped shroud 44. The v-shaped shroud 44 may direct the mist 118 toward and through the filter structure 56 toward the top of the filter structure 56.

The filter structure 56 can include multiple filters 58 positioned substantially parallel to one another. Each of the multiple filters 58 can be spaced apart by a specific distance, such as 1 cm, or any other desired distance. Thus, the multiple filters 58 can define multiple voids 92. The multiple filters 58 can store mist 118. The mist 118 can cool the air. The cooled air can travel through the voids 92 and exit the personal air cooler through one of the side panels. The side panel can be the side panel adjacent to the filter structure 56 and can include the outlet vent 52.

FIGS. 10-19 show an evaporative air cooler 200 for cooling air. The evaporative air cooler 200 may include a housing 220 having a top surface 222, a bottom surface 224, and four lateral sides, such as a front surface 226, a back surface 228, and a side surface 230. The housing 220 may be formed into a cube, a rectangular solid, a hemisphere, or any other suitable shape. The housing 220 may be formed from plastic or any other desired material.

The top surface 222 can include a lid, such as the lid 232. FIGS. 12 and 13 show the evaporative air cooler 200 with the lid 232 open for access to the tank 240. The lid 232 can be located along the front of the top surface 222. The lid 232 can include a lid tab 276 formed as the rear of the lid 232 or any other desired location. The lid 232 can be opened to allow water to fill the tank 240. For example, a user can pull the lid tab 276 upward to open the lid 232. The lid 232 can be formed from plastic or any other desired material. The tank opening 244 to the tank 240 can be any desired opening. When in the closed position, the lid 232 can be configured to cover the tank opening 244 to form a seal. The lid 232 and the tank opening 244 can be oval or any other suitable shape or configuration.

The front surface 226 may also include buttons, such as a power button 234 or any other desired button. The power button 234 may be configured to activate (e.g., power on), change the fan speed of the fan 248, and deactivate (e.g., power off) the evaporative air cooler 200. For example, when the power button 234 is activated once, the indicator light 238 may be turned on, the fan 248 may be turned on (e.g., to a high speed), and an aperture 242 positioned within the water tank 240 may allow water to flow out of the tank 240 to begin the evaporative air cooling process. When the power button 234 is activated a second time, the fan speed is decreased (e.g., to a medium speed) and the aperture 242 allows less water to flow out of the tank 240. When the power button 234 is activated a third time, the fan speed is decreased (e.g., to a low speed) and the aperture 242 allows less water to flow out of the tank 240. When the power button 234 is activated a fourth time, the indicator lights 238 can be turned OFF (e.g., no indicator lights 238 remain ON), the fan 248 can be turned OFF, and the aperture 242 can stop water from flowing out of the tank 240. In other words, the power button 234 can be activated to deactivate or power off the evaporative air cooler 200. In one embodiment, when the power button 234 is activated (e.g., pressed) for more than three seconds, the indicator lights 238 and the evaporative air cooler 200 can be turned OFF.

The front surface 226 may be configured to emit one or more lights, such as an indicator light 238 or any other desired light or indicator. The front surface 226 may include a translucent portion, such as a window 250. The indicator light 238 may be positioned in the tank 240 or any other desired area and may include one or more lights, such as a blue LED light, for illuminating the tank 240 and/or the window 250. The light may be used for environmental purposes, such as a night light, to indicate fan speed, to indicate that the evaporative air cooler 200 is on, or for any other desired purpose. When the evaporative air cooler 200 is powered on, the light may be turned on by default. The brightness of the indicator light 238 may be configured to vary. For example, after the power button 234 is pressed, the light may be in a high brightness mode. When the user presses the power button 234 a second time, the light may reduce its brightness (e.g., to a medium brightness mode). When the user presses the light button a third time, the light may reduce its brightness (e.g., to a low brightness mode). If the user presses the power button 234 a fourth time, the indicator light 238 may be turned OFF. In one embodiment, if the power button 234 is activated for a minimum amount of time (e.g., 3 seconds), a light setting may be selected and/or locked.

The power indicator light 236 may be used to indicate whether the evaporative air cooler 200 is low on battery, charging, or full, whether the filter 258 should be replaced, or any other desired indication. The power indicator light 236 may display a flashing light or a solid light. The power indicator light 236 may display different light colors, such as green, red, amber, or any other desired color.

The evaporative air cooler 200 may include a housing 220. The housing 220 may define an interior 254 of the evaporative air cooler 200. The interior 254 may be configured to receive a filter structure 256. The filter structure 256 may include a filter frame 282. The filter frame 282 may be formed from plastic or any other desired material. The filter structure 256 may be square, rectangular, or any other desired shape. The filter frame 282 may include a bottom wall 330, two side walls 332, and a top wall 334. As shown in FIG. 15 and FIG. 16A-C, the bottom wall 330 may be coupled to a base 336. The bottom wall 330 may be configured to lock into the base 336. The bottom wall 330 may include a bottom bar 338 that defines a bottom opening 340.

The upper and lower top walls 342, 344 can be coupled together via snaps or any other suitable means. The tabs 372 can be configured to angle downward toward a center portion of the filter structure 256. The tabs 372 can be configured to direct the mist 118, water, etc. toward the back of the filter structure 256. When the filter structure 256 is within the interior 254 of the evaporative air cooler 200, the tabs 372 can direct the water, mist 118, etc. toward the fan 248.

The filter structure 256 can include one or more filters, such as filters 258, 262. The filter 258 can be positioned through one of the bottom openings 340 from one side of one of the bottom bars 338 to the other side of the bottom bar 338. The filter 258 can be positioned around the top of one of the top bars 368. When the upper top wall 342 and the lower top wall 344 are in the locked position, the filter 258 and the top bar 368 are positioned in the slit 370. The filter 258 can include this configuration for each of the bars 338, 368, forming a zigzag configuration of the filter 258. Each of the ends of the filter 258 can be coupled to one of the side walls 332, the bottom wall 330, or any other suitable component. For example, the sidewall 332 can include hooks 364, and each end of the filter 258 can include an opening configured to receive one of the hooks 364.

The filter structure 256 can include a filter holder 284. The filter holder 284 can be coupled to the filter frame 282.

The filter holder 284 can be coupled to the filter frame 282 at a middle portion of each of the side walls 332. The filter structure 256 can be configured to be removed from the interior 254. The filter holder 284 can include a pull tab 272. The pull tab 272 can be positioned on a front side 348 of the filter structure 256. The pull tab 272 can be configured for a user to pull the pull tab 272 to remove the filter structure 256 from the interior 254 of the housing 220 and/or insert the filter structure 256 into the interior 254. In this example, a user can remove the grill 252 from the housing 220 and pull the pull tab 272 to remove the filter structure 256. The filter structure 256, including the filters 258, 262, is reusable. The filter structure 256 and the filters 258, 262 can be washed. The filter structure 256 and the filters 258, 262 are replaceable.

The interior 254 can include a filter structure stopper 308. The filter structure stopper 308 can be bonded to or formed on an interior portion of the side 230 and/or back 228. The filter structure stopper 308 can be formed from plastic or any other desired material. The filter structure stopper 308 can be configured to position the filter structure 256 at a desired location within the interior 254. In other words, the filter structure stopper 308 stops and/or generally holds the filter structure stopper 308 in place adjacent to but not in contact with the fan 248. As illustrated in FIG. 15 and FIG. 16A-16C, the filter structure 256 can include a filter structure stopper tab 310 bonded to or formed in a front portion of the filter structure 256. The filter structure stopper tab 310 can be formed from plastic or any other desired material. The filter structure stopper tab 310 can be configured to position the filter structure 256 at a desired location within the interior 254. In other words, the filter structure stopper tab 310 stops and/or generally holds the filter structure stopper 308 in place adjacent to the fan 248 but not in contact with the fan 248.

The filter holder 284 can include a bar 296 that defines an opening, such as a slit 298. The bar 296 of the filter holder 284 extends from one side of the filter holder 284 to the other side of the filter holder 284. The filter 258 can be positioned through each of the filter holders 284. The filter holder 284 can provide additional support for securing the filter 258 to the filter frame 282. The filter holder 284 can further help maintain the configuration of the filter 258 in a zigzag format when the filter 258 is dry, moist, wet, or a combination thereof.

The second filter 262 may be coupled to at least a portion of the perimeter 302 of the filter structure 256. In one embodiment, the second filter 262 is positioned adjacent the perimeter 302 of the top wall 334 and the side wall 332. Each end of the second filter 262 may be coupled to a bottom of each side wall 332. For example, the side wall 332 may include hooks 364, and each end of the second filter 262 may include an opening configured to insert one of the hooks 364. The second filter 262 may be configured to absorb the mist 118. The second filter 262 may be formed from the same material as the filter 258, such as a sponge material 260, or any other suitable material. The second filter 262 may be in fluid communication with the filter 258. The filter 258 may absorb the liquid and/or mist 118 absorbed by the second filter 262. For example, a portion of the filter 258 can be positioned through the top wall 334 of the filter structure 256 and adjacent to a second filter 262 positioned adjacent the top wall 334 (e.g., along the perimeter 302 of a portion of the filter frame 282). The filters 258, 262 can be in contact with each other or adjacent to each other. The second filter 262 can be coupled to the two side walls 332, the bottom wall 330, any other suitable wall, or a combination thereof. In one embodiment, the filters 258, 262 are the same filter. In another embodiment, the second filter 262 is not included in the filter structure 256.

The filter 258 can be configured in a zigzag fashion to define a gap 292. The filter 258 can be configured to store liquid, such as mist 118, water, any other suitable liquid, or a combination thereof. The filter is configured to absorb mist 118 from a mister, absorb liquid from being pre-soaked, store liquid by being frozen, or any other suitable means of absorbing or storing liquid.

The fan cover 246 can be configured to form a suction force with the fan to provide additional force in directing air from the exterior of the housing 220 through the fan cover 246, the filter structure 256, and the grille 252. In this manner, the fan cover 246 can be configured to direct airflow through the interior 254 of the evaporative air cooler 200.

The fan 248 may be positioned adjacent to one of the sides of the housing 220, such as the back surface 228. The fan 248 may be configured to draw air into the evaporative air cooler 200, such as through a grate opening 300 in the back surface 228 of the housing 220.

The fan 248 may include a motor 266. The motor 266 may be used to control the fan 248 to rotate the blades 264. The motor 266 may rotate the blades 264 at various speeds. The speed at which the blades 264 rotate may vary the amount (e.g., volume) of air and the speed at which the air flows through the filter structure 256 and out of the interior 254 of the evaporative air cooler 200. Evaporative air cooler 200 can include different levels of speed, each of which can be configured to direct air. The higher level can direct a larger volume of air at a first speed. The mid-range level can direct a mid-range amount of air at a second speed. The lower level can direct a smaller volume of air at a third speed. The first speed can be greater than the second speed. The second speed can be greater than the third speed. Evaporative air cooler 200 can be configured to have predefined speeds, variable speeds, or any combination thereof.

Fan 248 may be hardwired to evaporative air cooler 200. Wiring 322 may be soldered or attached in any other desired manner to electrically connect fan 248 to evaporative air cooler 200. Wiring 322 may be hidden in a wiring compartment or any other desired compartment within evaporative air cooler 200.

18, the rear surface 228 may include a lattice 294 that defines a lattice opening 300. The lattice opening 300 may be configured throughout the lattice 294. The lattice 294 may be a portion of the rear surface 228, such as a central portion of the rear surface 228. The lattice 294 may be rectangular, square, circular, oval, or any other suitable shape. The lattice opening 300 may include one or more shapes (e.g., circular, rectangular, oval, any other suitable shape, or combinations thereof). Air, such as ambient air, may enter the interior 254 of the evaporative air cooler 200 from outside the housing 220 through the lattice opening 300 of the lattice 294. The lattice 294 may be configured to protrude from the rear surface 228. The fan 248 may be coupled to the rear surface 228. More specifically, the lattice 294 may include a fan coupling portion 288 that couples to the fan 248. The protrusion of the lattice 294 from the rear surface 228 may be configured to accommodate the fan 248.

The evaporative air cooler 200 can be powered by a power source, such as a battery or any other suitable power source. The battery can be a rechargeable battery, such as a lithium ion battery (LIB) or any other rechargeable power source. The evaporative air cooler 200 can include a charging port (not shown) to charge the rechargeable battery. The charging port can be located on the back 228, or any other desired location on the evaporative air cooler 200. The charging port (not shown) can be configured to receive a charger 268. The evaporative air cooler 200 can operate using a rechargeable battery and/or when plugged into an electrical outlet.

14 and 17, the front surface 226 of the housing 220 may define an opening, such as a front opening 286. The grill 252 may be coupled to the front surface 226 to cover the front opening 286. The grill 252 may include grill tabs 274 configured to secure the grill 252 to the housing 220. The grill tabs 274 may be coupled to the grill 252 or formed within the grill 252. The grill tabs 274 may be positioned at each of the corners of the grill 252. The grill 252 may be configured to removably couple to the front surface 226 of the housing 220. Each grill tab 274 may be inserted into one of the openings 324 in the housing 220. The openings 324 may be located in the bottom surface 224, the front surface 226, or any other desired location within the housing 220. When coupled to the housing 220, the grill 252 may provide a front side of the housing 220. The grille 252 may include vents 270 (e.g., bars). The vents 270 may be configured in a horizontal configuration, an angled configuration, any other suitable configuration, or a combination thereof. The vents 270 may be stationary. The vents 270 may be configured to rotate. Each of the vents 270 may be aligned parallel to one another such that the vents 270 are configured to allow air to pass through the vents 270.

The evaporative air cooler 200 can include an angled member 210. The angled member can be coupled to the housing 220. The angled member can include arms 352, 354 and a base 356. The first arm can be rotatably coupled to one of the sides 230 of the housing 220. The second arm 354 can be rotatably coupled to the opposing side 230. In one embodiment, the first and second arms 352, 354 are coupled to a central portion of the side 230. The arms may be coupled to the sides via couplings 358, such as a ratchet system or any other desired rotatable attachment. The angled member can be configured to rotate the housing 220. The angled member can rotate the housing 220 to position the housing 220 at an angle desired by a user. The angled member can be configured to rotate the housing 220 vertically. The angled member 210 can be configured to rotate the housing 220 360 degrees. The angle member 210 can maintain the position or angle of the housing 220 relative to the angle member 210. For example, if a user wants the evaporative air cooler 200 to blow cooled air towards the user's face, the user can rotate the housing 220 upward to direct the cooled air upward. Similarly, the user can rotate the housing 220 downward to direct the cooled air downward. The arms 352, 354 can be coupled to the sides such that the housing 220 is stationary and cannot rotate about the arms.

The first and second arms 352, 354 can protrude from opposite sides of the base 356. The first and second arms 352, 354 can be formed with or coupled to the base 356. The base 356 can be formed from plastic or any other suitable material. The base 356 can be coupled to the clip 202 via a coupling 360, such as a ratchet system or any other desired rotatable attachment. The coupling 360 can be configured to rotate the housing 220 360 degrees or any other desired degree of rotation in either direction (e.g., right or left) via the base 356.

The evaporative air cooler 200 can include a fastener, such as a clip 202. The clip 202 can be rotatable or actuated by a spring 380 and can be a device for holding an object or objects together or in place. For example, the clip 202 can be configured to removably couple the evaporative air cooler 200 to a handle 206 of a stroller 204, a countertop 208, a desk, a table, or any other suitable object. The clip 202 can include grips 382, 384 on one or more components of the clip 202. For example, the grip 382 can be configured on a grip side 388 of the clip 202 and the grip 384 can be configured on a grip side 390 of the clip base 376. The grips 382, 384 can be configured to more securely attach the evaporative air cooler 200 to an object. The grips 382, 384 can be formed of rubber, plastic, or any other desired material. The grips 382, 384 may be formed as ridges and/or smooth surfaces. The smooth surfaces may be configured to protect the object to which the clip 202 is attached so that the clip 202 does not damage (e.g., scrape, scratch, etc.) the object.

The clip 202 may be coupled to the clip base 376 via a coupling 392. The coupling 392 may include a rod 386 configured to be inserted into a rod holder 394, 396. The rod holder 394 may be coupled to or formed at an end of one of the sides of the clip. The rod holder 396 may be coupled to or formed at the grip side 390 of the base. Each of the rod holders 394, 394 may define an opening through which the rod 386 is inserted. The spring 380 may define an opening through which the rod 386 is configured to pass. The spring 380 may provide tension to the clip 202 relative to the clip base 376. In the closed position, the clip 202 may be configured such that one end of the clip 202 (e.g., the grip end 398) extends further than the clip base 376. The gripping end 398 is configured so that a user can rotate the clip 202 by exerting a force on the gripping end 398 to rotate the clip 202 about the coupling portion 392. The user can open the clip 202 to insert an object into the clip 202. When the user releases the clip 202, the tension provided by the spring 380 couples the clip 202 to the object and secures the evaporative air cooler 200 in a desired location.

The clip 202 may include one or more support members 400. The one or more support members 400 may be configured on either side of the clip 202, along the clip 202, or in any other desired location. The one or more support members 400 may be configured to support the evaporative air cooler 200 in an upright position when the clip 202 is in the closed position. In other words, the one or more support members 400 support the evaporative air cooler 200 so that it does not easily tip over when placed on a surface. Similarly, the clip base 376 may include a front surface 378 configured to support the evaporative air cooler 200 when placed on a surface (e.g., with the clip in the closed position). The front surface 378 may protect components of the coupling 392 from being damaged. For example, the front surface 378 may stop the clip 202 from being over-rotated such that the spring 380 is over-extended.

The clip 202 may be coupled to the angled member 210. Specifically, the clip base 376 may be coupled to the base 356 of the angled member 210. The clip base 376 may be rotatably coupled to the base 356, such as the bottom of the base 356. The clip base 376 may be coupled to the base 356 via a coupling 360, such as a ratchet system or any other desired rotatable attachment. The base 356 may be configured to rotate the housing 220 horizontally about the clip base 376. The base 356 may rotate horizontally 0-360 degrees in either direction about the clip base 376. For example, a user may attach the evaporative air cooler 200 to the countertop 208 via the clip 202. The user may rotate the housing 220 of the evaporative air cooler 200 horizontally, via the base 356, toward the user. The user can further rotate the housing 220 vertically, via the angled member 210, towards the user. In this manner, when the evaporative air cooler 200 is turned on, cooled air can be directed towards the user. In another embodiment, the housing 220 can be coupled to the angled member 210 and the base 356 can be coupled to the clip base 376 such that the housing 220 is stationary and cannot rotate horizontally and/or vertically.

13 and 14, the evaporative air cooler 200 can include a tank 240. The tank 240 can be positioned adjacent to the top surface 222 of the housing 220. The top surface 222, the front surface 226, the back surface 228, and a portion of the interior of the side surface 230 of the housing 220 can form part of the tank 240. For example, the tank 240 can be configured within the housing 220 such that the top of the tank 240 is below the top surface 222 of the housing 220. The tank 240 can include a front side and a bottom side coupled to the housing 220. The front side and the bottom side of the tank 240 can include a window 250. A light, such as the power indicator 236, can be positioned adjacent to the bottom side of the tank 240 or in any other desired location. The bottom side of the tank 240 and the front of the tank 240 can include a window 250 and can be configured to emit light generated by the power indicator 236 throughout the tank 240. The power indicator 236 may also be configured to emit light into the interior 254 and toward the exterior of the evaporative air cooler 200.

The tank 240 may include a liquid inlet 312 and a liquid outlet 314. The top of the housing 220 may define an opening, such as the liquid inlet 312. The liquid inlet 312 may be oval, circular, or any other desired shape. The bottom of the tank 240 may define an opening, such as the liquid outlet 314. The liquid outlet may be oval, circular, or any other desired shape. The liquid outlet 314 may be positioned at the bottom of the tank 240. The liquid outlet 314 may be positioned at a central location at the bottom of the tank 240. The liquid outlet may be positioned adjacent to the filter structure 256. The liquid outlet 314 may be configured to receive the atomizing structure 304 including the atomizer 306. A liquid, such as water, may enter the tank 240 through the liquid inlet 312 and exit the tank 240 through the liquid outlet 312. In response to liquid flowing through the liquid outlet 314, the mist generator 306 can be configured to generate mist from the liquid within the interior 254 of the evaporative air cooler 200.

12 and 13, the lid 232 can be coupled to the top surface 222 or any other suitable portion of the housing 220. The lid 232 can be coupled to the top surface 222 via a hinge, a cord, or any other suitable attachment. A portion of the lid 232 can be configured to fit within the liquid inlet 312. For example, if the liquid inlet 312 is oval shaped, the lid 232 can be a slightly smaller oval shape to fit within the liquid inlet 312 and form a seal 316 when the lid 232 is in a closed position. The lid 232 can include an oval seal 316 to form a seal with the liquid inlet 312 such that the liquid remains within the tank 240. The lid 232 can be formed from plastic or any other desired material. The seal 316 can be formed from rubber or any other desired material. The tank 240 can be configured to receive, store, and release liquid. For example, when the lid 232 is open (see FIG. 13), liquid can be poured into the tank 240 using a pitcher, faucet, water bottle, or any other desired filling means.

The atomizer 306 may be positioned adjacent to the tank 240. The atomizer 306 may be coupled to the liquid outlet 314. The atomizer 306 may be in fluid communication with the tank 240. Liquid may flow from the tank 240 through the top of the atomizer 306 to the bottom of the atomizer 306. The atomizer 306 may be configured to generate a mist 118 from the liquid stored in the tank 240. The atomizer 306 may distribute the mist 118 into the air and into the interior 254 of the evaporative air cooler 200 and over a filter, such as the second filter 262. The mist 118 may cool the air in the interior 254.

When the evaporative air cooler 200 is operating, the atomizer 306 can generate the mist 118. For example, the atomizer 306 can be configured to generate a first amount of the mist 118 when the fan 248 is at a first speed. The atomizer 306 can be configured to generate a second amount of the mist 118 when the fan 248 is at a second speed (the opening 242 of the atomizing structure 304 can allow less water to flow out of the tank 240). The atomizer 306 can be configured to generate a third amount of the mist 118 when the fan 248 is at a third speed. The first amount can be greater than the second amount, and the first speed can be faster than the second speed. In other words, when the fan 248 is high, a larger amount of the mist 118 can be sprayed from the atomizer 306. Similarly, the first amount and the second amount can be greater than the third amount, and the first speed and the second speed can be greater than the third speed. Evaporative air cooler 200 can have a button, such as power button 234, to control the speed of fan 248. For example, when power button 234 is engaged for a first time, fan 248 can operate at a first speed. When power button 234 is engaged for a second time, fan 248 can operate at a second speed. When power button 234 is engaged for a third time, fan 248 can operate at a third speed. When power button 234 is engaged for a fourth time, fan 248 can be turned off (i.e., terminating operation of fan 248). Evaporative air cooler 200 can have any number of speeds and is not limited to those described in this disclosure. Evaporative air cooler 200 can have a light (e.g., power indicator 236), such as an LED light or any other desired light, to indicate that evaporative air cooler 200 is operating. The power indicator 236 can be configured to indicate the speed of operation.

The evaporative air cooler 200 may include a safety interlock 320. The safety interlock 320 may be configured to prevent operation of the evaporative air cooler 200. For example, if at least one of the grill 252 and the filter structure 256 is removed from the housing 220, the safety interlock 320 may shut off operation of the evaporative air cooler 200. The safety interlock 320 may function as a safety feature to prevent a user from touching the fan blades while the fan is rotating during operation.
