The following describes in detail the embodiments of the present invention. Examples of the embodiments are shown in the drawings, in which the same or similar reference numerals indicate the same or similar components or components having the same or similar functions. The embodiments depicted with reference to the attached drawings below are examples and are used only to interpret the present invention, and should not be understood as limitations on the present invention.

Referring to Fig. 1, an embodiment of the present application provides a cleaning appliance 100 for washing clothes or shoes. Referring to Fig. 2 and Fig. 3 together, an embodiment of the present application provides one kind of pulsator 20. The pulsator 20 may be used in the cleaning appliance 100 of the embodiment of the present application. For example, the pulsator 20 may be used in the cleaning appliance 100 shown in the schematic diagram of Fig. 1. The pulsator 20 may also be used in other embodiments of the cleaning appliance 100, such as a washing machine, a shoe washing machine, etc., to improve the cleaning ability of the cleaning appliance 100.

2 and 3, the pulsator 20 of the embodiment of the present application includes a rotor disk 22 and vanes 23 provided on the rotor disk 22. The rotor disk 22 is provided with an inlet 221 to allow external fluid to enter the rotor disk 22. The vanes 23 communicate with the inside of the rotor disk 22 and are provided with an outlet 211 on a side 231 of the vanes 23 to allow the fluid in the rotor disk 22 to flow out. When the fluid in the rotor disk 22 receives suction force along the direction from the inlet 221 to the outlet 211, the fluid flowing out from the vanes 23 can rotate the pulsator 20.

With reference to FIG. 1, the cleaning device 100 includes a washing container 10, and when the cleaning device 100 washes the items, cleaning liquid is stored in the washing container 10. The cleaning liquid contains dissolved laundry detergent such as powder detergent and liquid detergent. The fluid in the pulsator 20 enters the washing container 10 from the outlet 211 on the side 231 of the blade 23, and as the pulsator 20 rotates, the blade 23 stirs the cleaning liquid in the washing container 10 to form a turbulent flow, which dissolves stains in the liquid and makes it easier to separate them from the items, thereby enhancing the cleaning effect and shortening the cleaning time. The fluid that enters the washing container 10 from the pulsator 20 collides with the cleaning liquid in the washing container 10 to generate bubbles, which burst when they come into contact with the items, generating vibrations that remove stains without damaging the items, thereby enhancing the cleaning effect.

Here, items to be washed include, but are not limited to, clothing, shoes, cloth, towels, etc.

Conventional cleaning equipment 100 separates stains mainly by friction between the pulsator 20 and the items being washed. The pulsator 20 of the embodiment of the present application rotates by the propulsive action of the fluid flow, stirring the cleaning liquid in the washing container 10 to form turbulence, and the fluid that enters the washing container 10 collides with the cleaning liquid to generate air bubbles, which removes stains through the turbulence and air bubbles, improving the cleaning effect. Compared to a conventional pulsator 20 that is driven by a motor, the friction generated when the pulsator 20 of the present application comes into contact with the items being washed is smaller, so damage to the items being washed can be avoided.

Referring to FIG. 4, in some embodiments, the pulsator 20 includes a rotor disk 22 and blades 23 provided on the rotor disk 22. As the blades 23 rotate with the rotor disk 22, they rotate the liquid in the washing container 10 to form a turbulent flow. Since the liquid in a conventional pulsator washing machine does not flow turbulently, when the flowing liquid comes into contact with the items to be washed, a stable saturated layer is formed on the surface of the items to be washed, making it difficult to separate stains from the items to be washed. When the turbulent flow comes into contact with the items to be washed, a stable saturated layer is not formed on the surface of the items to be washed, and the stains dissolve in the liquid due to the turbulent flow, making it easy to separate from the items to be washed, thereby improving the cleaning effect and shortening the cleaning time.

Referring to FIG. 5, in some embodiments, the blades 23 are provided on the peripheral surface 221 of the rotor disk 22. For example, the roots of the blades 23 are connected to the peripheral surface 221 of the rotor disk 22. Referring to FIG. 1, the rotor disk 22 and the blades 23 are positioned close to the bottom wall 16 of the laundry container 10, so that the pulsator 20 does not easily come into contact with the items being washed during the rotation process, thereby preventing damage to the items being washed due to friction between the pulsator 20 and the items being washed.

The pulsator 20 will be further described below with reference to the attached drawings.

1 and 2, in some embodiments, the cleaning device 100 includes a fluid suction assembly 40. The fluid suction assembly 40 is connected to the laundry container 10 and is used to suck the fluid in the storage space 11 of the laundry container 10. The flow rate of the fluid sucked from the laundry container 10 is greater than the flow rate of the fluid flowing into the laundry container 10 from the outlet 211, so that the storage space 11 of the laundry container 10 forms a negative pressure. Under the action of the negative pressure, the fluid in the pulsator 20 is sucked into the storage space 11, and the fluid sucked into the storage space 11 drives the pulsator 20 to rotate.

2 and 3, in some embodiments, there are multiple blades 23, and the shape of the multiple blades 23 is spiral-shaped so that the washing liquid in the washing container 10 can be stirred and turbulent flow can be formed when the blades 23 rotate. When the liquid is stored in the storage space 11 and the fluid enters the storage space 11 through the pulsator 20 rotating at high speed, the fluid collides with the liquid in the storage space 11 and generates a large amount of bubbles, and when the bubbles come into contact with the item to be washed, they burst and generate vibrations, which remove stains from the item to be washed. Therefore, unlike conventional motor-driven pulsators, the pulsator 20 of the embodiment of the present application removes stains from the item to be washed by forming foam water and turbulence, thereby improving the cleaning effect and preventing damage to the item to be washed by avoiding increased friction on the item to be washed.

Referring to FIG. 3, in some embodiments, the vanes 23 are evenly distributed around the inlet 221. This is advantageous for the power balance when the vanes 23 rotate, stabilizing the rotation of the pulsator 20 and reducing the degree of rocking or vibration of the pulsator 20 during rotation.

The shape of the multiple blades 23 can also be selected to be spiral.

Referring to FIG. 3, in some embodiments, each vane 23 is provided with an outlet 211, and the distance between the center of each outlet 211 and the center of the inlet 221 is the same. Among them, the distance between the center of each outlet 211 and the center of the inlet 221 is the same, that is, each outlet 211 is located at the same position on a concentric circle centered on the center of the inlet 221. In the process of the fluid being sucked into the storage space 11 from the outlet 211, power is provided to rotate the pulsator 20, and since the distance between the center of each outlet 211 and the center of the inlet 221 is the same, the position of each outlet 211 provides the same moment of force to the rotation of the pulsator 20, which is favorable for the power balance when the vane 23 rotates, and the rotation of the pulsator 20 can be stabilized and the degree of rocking or vibration of the pulsator 20 during rotation can be reduced.

In some embodiments, multiple outlets 211 are provided for each blade 23, thereby increasing the amount of fluid flowing into the laundry receptacle 10 and increasing the power of rotation of the pulsator 20 provided by the fluid. The outlet 211 of each blade 23 can be located on a concentric circle centered on the center of the inlet 221 with at least one outlet 211 of the other blades 23. Therefore, the force moments provided to the rotation of the pulsator 20 at the outlets 211 between different blades 23 can be balanced, ensuring stable rotation of the pulsator 20.

In one embodiment, for manufacturing convenience, the size of each outlet 211 on the same vane 23 is the same. To provide uniform power along the radial direction of the vane 23, the distance between two adjacent outlets 211 on the same vane 23 is the same.

In yet another embodiment, for the same vane 23, the size of the outlet 211 gradually increases from one end close to the center of the inlet 221 to the other end farther from the center of the inlet 221. That is, the closer to the outside of the vane 23, the larger the size of the outlet 211, and the closer to the inside of the vane 23, the smaller the size of the outlet 211. In this case, the moment provided by the outlet 211 on the outside of the vane 23 to the rotation of the pulsator 20 is larger, which is the main force for rotating the pulsator 20. The fluid flowing out from the outlet 211 near the inside of the vane 23 is mainly used to ensure stable rotation of the pulsator 20, stabilize the force that the vane 23 receives along the radial direction, and reduce the degree of rocking or vibration when the pulsator 20 rotates. From one end close to the center of the inlet 221 to the other end farther from the center of the inlet 221, the distance between adjacent outlets 211 gradually decreases. That is, the closer to the outside of the blades 23, the denser the distribution of the outlets 211, and the closer to the inside of the blades 23, the sparser the distribution of the outlets 211, which allows for greater power to be applied closer to the outside of the blades 23 and increases the rotational speed of the pulsator 20.

In some embodiments, the shape of the outlet 211 may be circular, rectangular, triangular, etc., but is not limited thereto. In one embodiment, the shape of the outlet 211 is circular because it is easy to manufacture and can also improve the area utilization of the side surface of the blade 23.

In some embodiments, the number of the vanes 23 is an odd number, for example, the number of the vanes 23 may be 3, 5, 7, etc., not listed here one by one. An odd number of vanes 23 can reduce resonance during the rotation process and improve the dynamic balance of the rotation of the vanes 23.

In some embodiments, the number of the blades 23 is an even number, and the shapes of the blades 23 are not perfectly identical to reduce resonance during the rotation process and improve the dynamic balance of the rotation of the blades 23. For example, the number of the blades 23 is four, and the size of any one of the blades 23 is different from the size of the other three blades 23. The equivalent center of gravity of the blades 23 is located at the center of the inlet 221 to ensure dynamic balance.

Referring to FIG. 3, in some embodiments, the rotor disk 22 has a first surface 225, a second surface 226, and a side surface 227. The first surface 225 and the second surface 226 face in opposite directions, the side surface 227 of the rotor disk 22 is connected to the first surface 225 and the second surface 226, the inlet 221 is drilled in the first surface 225, and the vanes 23 are provided on the second surface 226. The vanes 23 can be positioned closer to the inlet 221, so that the vanes 23 are provided on the second surface 226, and the moment arm corresponding to the moment at the outlet 211 is shorter, and the fluid provides more power to the pulsator 20.

In one embodiment, the blades 23 are located within the second surface 226 (i.e., the top surface) and the circumference of the rotor disk 22 is the outermost circumference of the entire pulsator 20, thereby reducing the size of the pulsator 20 along the horizontal direction, and the outlet 211 is closer to the center of rotation of the pulsator 20, i.e., the center of the inlet 221, and the moment arm corresponding to the moment at the outlet 211 is shorter , allowing the fluid to impart greater force to the pulsator 20.

In another embodiment, the blades 23 partially protrude from the second surface 226, i.e., the distance from the end of the blades 23 away from the center of the inlet 221 to the center of the inlet 221 is greater than the radius of the second surface 226. In this case, the blades 23 can rotate the fluid in the laundry container 10 to generate a larger vortex area, thereby providing a larger cleaning area.

In some embodiments , the position of the blade 23 is on the second surface 226 and the position of the pulsator 20 is close to the bottom wall 16 of the laundry container 10, so that the distance between the highest point of the top of the blade 23 and the second surface 226 is within the range of [2.0 cm, 4.0 cm], and the blade 23 does not easily come into contact with the items being washed during the rotation of the pulsator 20, thereby preventing damage to the items being washed due to friction between the pulsator 20 and the items being washed.

Referring to FIG. 4, in some embodiments, the side 231 of the blade 23 extends from the second surface 226 to expand the range in which the blade 23 rotates the fluid and generate a wider range of vortexes. The blade 23 further includes a connecting surface 233, which is used to connect the second surface 226 and the side 231 of the blade 23 at an angle, and the connecting surface 233 is a streamlined arc surface, which can reduce flow resistance, make the rotation of the pulsator 20 smoother, and generate turbulence.

Referring to FIG. 1 and FIG. 3, in some embodiments, the pulsator 20 is provided with a flow path 21 communicating with the storage space 11, and the external fluid enters the storage space 11 via the flow path 21. The fluid inlet assembly 30 includes an inlet pipe 32, which passes through the first end 12 of the laundry container 10 and communicates with the inlet of the flow path 21, so that the external fluid can enter the flow path 21 via the inlet pipe 32.

Referring to FIG. 3, in some embodiments, a plurality of guide members 25 are provided in the rotor disk 22, each of which corresponds to one of the blades 23 and surrounds the corresponding blade 23 to form one flow passage 21, one end of each flow passage 21 being connected to an inlet 221 and a drilled outlet 211 being provided in the blade 23 at the other end. Fluid enters the flow passage 21 from the inlet 221 and enters the storage space 11 from the outlet 211 under the action of negative pressure in the laundry container 10.

In some embodiments, the shape of the guide member 25 corresponds to the blades 23, and the multiple guide members 25 form a vortex-shaped flow passage 21 in accordance with the blades 23, thereby acting as a guide for the fluid in the pulsator 20, making it easier for the fluid flowing from the pulsator 20 into the storage space 11 to form a vortex, which can generate turbulence.

Referring to FIG. 5, in some embodiments, each flow path 21 is divided into a first sub-flow path 214 and a second sub-flow path 215 that are separated from each other, and outlets 211 are provided on two sides of the blade 23 facing in opposite directions. The pulsator 20 is further provided with a valve 27 provided in the rotor disk 22 and corresponding to the flow path 21, and the valve 27 is used to selectively connect the first sub-flow path 214 to the inlet 221 so that the fluid flowing out of the outlet 211 on one side of the blade 23 can rotate the pulsator 20 in the forward direction, and to selectively connect the second sub-flow path 215 to the inlet 221 so that the fluid flowing out of the outlet 211 on the other side of the blade 23 can rotate the pulsator 20 in the reverse direction.

5, for example, the blade 23 has a first side 2314 and a second side 2315 facing in opposite directions, the first side 2314 is provided with a first outlet 2114, the second side 2315 is provided with a second outlet 2115, the first sub-channel 214 is connected to the first outlet 2114 and the inlet 221, and the second sub-channel 215 is connected to the second outlet 2115 and the inlet 221. It is assumed that the counterclockwise rotation direction of the pulsator 20 is the forward rotation direction, and the clockwise rotation direction is the reverse rotation direction. When the valve 27 is turned clockwise, the fluid in the second sub-channel 215 is blocked from entering the storage space 11 of the washing container 10 through the second outlet 2115, and at the same time, a path is opened for the fluid to flow out of the first outlet 2114 via the first sub-channel 214, allowing the fluid in the pulsator 20 to flow into the storage space 11 through the first outlet 2114, and the fluid in the first outlet 2114 is "sucked" into the storage space 11 under the action of negative pressure, causing the pulsator 20 to rotate forward. When the valve 27 is turned counterclockwise, the fluid in the first sub-channel 214 is blocked from entering the storage space 11 of the washing container 10 through the first outlet 2114, and at the same time, a path is opened for the fluid to flow out of the second outlet 2115 via the second sub-channel 215, allowing the fluid in the pulsator 20 to flow into the storage space 11 through the second outlet 2115. The fluid at the second outlet 2115 is "sucked" into the storage space 11 under the action of negative pressure, causing the pulsator 20 to rotate in the reverse direction.

In other embodiments, the clockwise direction of rotation of the pulsator 20 can be assumed to be the forward direction of rotation and the counterclockwise direction of rotation can be assumed to be the reverse direction of rotation, but is not limited thereto.

6, in some embodiments, the first outlet 2114 and the second outlet 2115 are provided on two opposite sides of the blade 23, respectively, the first outlet 2114 is provided with a first valve 271, and the second outlet 2115 is provided with a second valve 272. It is assumed that the counterclockwise rotation of the pulsator 20 is the forward rotation direction, and the clockwise rotation is the reverse rotation direction. When the first valve 271 and the second valve 272 are both closed, the fluid cannot enter the storage space 11 of the washing container 10 from the pulsator 20, and in this state, the fluid in the storage space 11 is sucked in, and the storage space 11 reaches a predetermined negative pressure value before the fluid in the pulsator 20 enters the storage space 11, and the pulsator 20 rotates at a predetermined rotation speed under the action of the predetermined negative pressure, and the rotation of the pulsator 20 can stir the cleaning liquid in the storage space 11 to form a turbulent flow. When the first valve 271 is open and the second valve 272 is closed, the fluid can enter the storage space 11 from the first outlet 2114 and rotate the pulsator 20 clockwise. When the first valve 271 is closed and the second valve 272 is open, the fluid can enter the storage space 11 from the second outlet 2115 and rotate the pulsator 20 counterclockwise.

The opening and closing directions of the first valve 271 and the second valve 272 can be translated vertically, similar to the opening and closing directions of a rolling door, and can also be rotated horizontally, similar to the opening and closing directions of a cabinet door, which is not limited here.

Referring to FIG. 3, in some embodiments, the rotor disk 22 includes a first disk 228 and a second disk 229 coupled to each other, the inlet 221 passes through the first disk 228, the guide member 25 is provided on the side of the first disk 228 close to the second disk 229 and surrounds the inlet 221, and the blade 23 is provided on the second disk 229 and protrudes from the side of the second disk 229 away from the first disk 228. For convenience of manufacture, the blade 23 and the guide member 25 are provided on the first disk 228 and the second disk 229, respectively, so that the first disk 228 and the second disk 229 having different shapes of blades 23 can be adapted, and have higher versatility.

In some embodiments, the first plate 228 and the second plate 229 are coupled to each other by a non-removable coupling method, such as welding, gluing, etc. In some other embodiments, the first plate 228 and the second plate 229 are coupled to each other by a removable coupling method, such as a snap fit, a threaded connection, etc., which are not limited herein.

Referring to FIG. 3, in some embodiments, the inlet 221 is circular in shape to better fit a circular pipeline. Referring to FIG. 7, in some embodiments, the inlet 221 is curled in shape to provide a certain flow-guiding effect to guide the fluid in the pulsator 20 into the flow passage 21 of the corresponding guide member 25.

Referring to FIG. 7, in some embodiments, the guide member 25 has an inclined surface 251, the lower part of the inclined surface 251 being close to the inlet 221 and the higher part of the inclined surface 251 being close to the side wall of the guide member 25, the inclined surface 251 partially shielding the inlet 221 so that the inlet 221 forms a spiral shape, and the fluid entering the pulsator 20 from the inlet 221 enters the corresponding flow passage 21 under the guiding action of the inclined surface 251.

Referring to FIG. 1, an embodiment of the present application provides a cleaning device 100 including a laundry container 10 and a pulsator 20. The laundry container 10 includes a storage space 11, and the pulsator 20 is provided within the storage space 11.

The pulsator 20 is a pulsator described in any one of the above-mentioned embodiments of the present application.

In some embodiments, the cleaning device 100 further includes a fluid inlet assembly 30 and a fluid suction assembly 40. The fluid inlet assembly 30 is attached to the laundry container 10 and communicates the storage space 11 with the outside through the pulsator 20. The fluid suction assembly 40 is connected to the laundry container 10 and is used to suck in the fluid in the storage space 11 and rotate the pulsator 20 by allowing the external fluid to enter the pulsator 20 via the fluid inlet assembly 30.

The cleaning device 100 according to the present application sucks in the fluid in the storage space 11 through the fluid suction assembly 40, forming a negative pressure in the storage space 11, and under the action of the negative pressure, the external fluid can flow into the pulsator 20 through the fluid inflow assembly 30, so that the flow of the external fluid rotates the pulsator 20 at high speed. When liquid is stored in the storage space 11, when the fluid enters the storage space 11 through the rotating blade plate 22 rotating at high speed, the fluid collides with the liquid in the storage space 11 and generates a large amount of bubbles, and when the bubbles come into contact with the item to be washed, they burst and generate vibrations, which can remove stains on the item to be washed. Therefore, the laundry container 10 of the cleaning device 100 does not rotate, and the cleaning device 100 does not shake violently during operation, avoiding damage to the item to be washed due to violent shaking. When the pulsator 20 rotates, the cleaning device 100 removes stains without relying on friction between the pulsator 20 and the item to be washed, and can avoid damage to the item to be washed due to large frictional forces.

Referring to Figures 1 and 2, in some embodiments, the cleaning device 100 further includes a lid 90 for closing the upper part of the storage space 11 of the laundry container 10. The cleaning device 100 may further include an upper tube portion 81 and a lower tube portion 82. The upper tube portion 81 and the lower tube portion 82 may be assembled to form a fitting tube to fit the laundry container 10 to protect the laundry container 10. The lid 90 closes the upper part of the storage space 11 of the laundry container 10 by connecting to the upper tube portion 81.

In some embodiments, the lid 90 can be removed from the upper barrel portion 81 to inject liquid into the storage space 11.

1 and 9 to 12, the laundry container 10 has a first end 12 and a second end 13 facing in opposite directions, the fluid inlet assembly 30 is provided at the first end 12, and the fluid suction assembly 40 is provided at the second end 13. As shown in FIG. 1, the first end 12 and the second end 13 facing in opposite directions specifically mean that the first end 12 is located below the center line 14 of the laundry container 10, and the second end 13 is located above the center line 14 of the laundry container 10, and are not limited to directly above and below the laundry container 10. For example, the laundry container 10 has a top wall 15, a bottom wall 16, and a side wall 17 connecting the top wall 15 and the bottom wall 16. In the embodiment shown in FIG. 1, the first end 12 is the bottom wall 16, the fluid inlet assembly 30 is provided at the bottom wall 16, the second end 13 is the top wall 15, and the fluid suction assembly 40 is provided at the top wall 15. In this case, the flow path of the fluid in the laundry container 10 is simplified, and the efficiency of suction of the fluid is improved. In the embodiment shown in FIG. 8, the first end 12 is located near the bottom wall 16 of the side wall 17, the fluid inlet assembly 30 is provided on the side wall 17, the second end 13 is the top wall 15, and the fluid suction assembly 40 is provided on the top wall 15. In this case, the external fluid can be introduced into the storage space 11 from the position of the side wall 17, so that the bottom wall 16 can be brought closer to the ground, and the size of the cleaning device 100 in the height direction can be reduced. In another embodiment, the second end 13 can be located near the top wall 15 of the side wall 17, and the fluid suction assembly 40 is provided on the side wall 17, so that the cleaning device 100 can extract the fluid in the storage space 11 from the side wall 17.

1, 11 and 12, in some embodiments, the position of the fluid inlet assembly 30 provided at the first end 12 faces the position of the fluid suction assembly 40 provided at the second end 13. Here, the fluid inlet assembly 30 is directly opposite the fluid suction assembly 40, i.e., the line connecting the center 31 of the fluid inlet assembly 30 and the center 41 of the fluid suction assembly 40 is parallel to the central axis 18 of the laundry container 10. This can reduce energy loss during the process of fluid flowing into and out of the laundry container 10. In one embodiment, the first end 12 is located at the bottom wall 16 and the second end 13 is located at the top wall 15, the fluid inlet assembly 30 is located at the center of the first end 12, and the fluid suction assembly 40 is also located at the center of the second end 13, and the line connecting the center of the fluid inlet assembly 30 and the center of the fluid suction assembly 40 overlaps with the central axis of the laundry container 10, thereby further reducing energy loss during the process of fluid flowing into and out of the laundry container 10. In other embodiments, the line connecting the center of the fluid inlet assembly 30 and the center of the fluid suction assembly 40 may be parallel to the central axis of the laundry receptacle 10 and offset from each other, but this is not a limitation hereof. The center of the fluid inlet assembly 30 and the center of the fluid suction assembly 40 may be offset from each other, but this is not a limitation hereof.

Referring to FIG. 1, in some embodiments, the fluid inlet assembly 30 further includes a valve (not shown). The valve is disposed in the inlet line 32 and is used to adjust the flow rate of the fluid flowing through the inlet line 32. By adjusting the flow rate of the fluid, the rotational speed of the pulsator 20 is adjusted to control the rotation of the pulsator 20, which moves the liquid in the laundry container 10 and generates turbulence.

In some embodiments, the valve is in a closed state before the fluid suction assembly 40 draws in air to create the predetermined negative pressure, which helps to create the predetermined negative pressure in the laundry container 10 by preventing external fluid from flowing into the laundry container 10 if the target negative pressure in the laundry container 10 has not yet reached the predetermined value.

Referring to FIG. 1 to FIG. 12, in some embodiments, the fluid suction assembly 40 includes a suction unit 42 provided outside the storage space 11, a power unit 43 provided outside the storage space 11, and a suction line 44. Depending on the type of fluid, the suction unit 42 can be a suction pump, a water pump, etc. The power unit 43 includes a motor, is connected to the suction unit 42, and is used to power the suction unit 42. The suction line 44 is inserted through the second end 13 of the laundry container 10 and is used to communicate the suction unit 42 with the storage space 11. The fluid in the storage space 11 is sucked into the suction line 44 by the action of the suction unit 42, and the fluid in the storage space 11 is extracted.

Referring to Figures 1-12, in some embodiments, the suction line 44 is attached to the lid 90 and is located within the storage space 11. The suction unit 42 and the power unit 43 are attached to the other side of the lid 90 and face in the opposite direction to the side where the suction line 44 is attached to the lid 90.

In some embodiments, the suction unit 42 can conveniently aspirate liquids.
The suction unit 42 is a water pump for sucking the liquid in the storage space 11 so that the suction pipe 44 is immersed in the liquid in the storage space 11, and the suction pipe 44 extends into the storage space 11 and has a certain height from the top wall 15 of the laundry container 10.

Referring to FIG. 8, in some embodiments, the suction line 44 includes a plurality of passages 441, each of which extends in a spiral radial shape from the center of the suction unit 42. In this way, air bubbles that enter the suction line 44 during the process of sucking fluid can be easily burst, improving suction efficiency, and the laundry detergent, such as powder detergent or liquid detergent, in the air bubbles can be re-entered into the laundry container 10, reducing the waste of laundry detergent and improving the utilization rate of the laundry detergent.

1, 3 and 8, in some embodiments, the suction line 44 is provided with a suction port 442 communicating with the storage space 11, and the fluid inlet assembly 30 is provided with an inlet line 32, and the opening size of the suction port 442 is larger than the opening size of the inlet 321 of the inlet line 32. As shown in FIG. 1 and FIG. 8, the suction port 442 is an outlet for the fluid to leave the storage space 11, and the size of the suction port 442 determines the maximum flow rate of the fluid to be extracted from the storage space 11. The flow rate of the fluid flowing out from the outlet 211 of the flow path 21 cannot exceed the flow rate of the fluid flowing into the inlet line 32 from the inlet 321, so the size of the inlet 321 determines the maximum flow rate of the fluid flowing into the storage space 11. Therefore, it can be ensured that the flow rate of the fluid outflow is greater than the flow rate of the fluid inflow, and the storage space 11 can always maintain a negative pressure, ensuring that the flow of the fluid to the fluid inlet assembly 30 can continue to enter the storage space 11 under the action of negative pressure.

1, in some embodiments, the external fluid includes gas, which enters the pulsator 20 via the fluid inlet assembly 30 to rotate the pulsator 20, and the fluid suction assembly 40 sucks the gas in the storage space 11 to form a negative pressure in the storage space 11. The suction port 442 and the inlet 321 form an air duct, and the air duct has a trumpet shape. That is, the diameter of the end of the air duct close to the inlet 321 is the smallest, and the diameter difference of the air duct increases in a gradient from one end of the inlet 321 to one end of the suction port 442. Therefore, the energy loss during the process of the gas flowing from the suction port 442 to the inlet 321 can be reduced, and the energy of the air flow can be efficiently utilized by avoiding turbulence.

Referring to FIG. 10, in some embodiments, the cleaning device 100 further includes a liquid storage container 50. The liquid storage container 50 is used to store the cleaning liquid and inject the cleaning liquid into the storage space 11. Here, the cleaning liquid may be a solution mixed with laundry detergent such as powder detergent and liquid detergent. Since the storage space 11 needs to maintain a negative pressure state during the cleaning process, the sealing of the laundry container 10 is required to a certain extent. Since there are many different types and dimensions of faucets, it is difficult to accommodate a wide variety of faucets with the water inlet channel (not shown) of the laundry container 10 while considering the sealing. The size of the water outlet channel 51 of the liquid storage container 50 matches the size of the water inlet channel of the laundry container 10, and both the water outlet channel 51 and the water inlet channel are sealed to ensure that the storage space 11 can be maintained in a negative pressure state.

In one embodiment, the liquid storage container 50 is detachably connected to the laundry container 10, and when not washing, the liquid storage container 50 and the laundry container 10 are stored or transported separately, so that the liquid storage container 50 and the laundry container 10 can be conveniently stored and moved. When it is necessary to inject cleaning liquid into the storage space 11 and the laundry container 10 is difficult to move, the liquid storage container 50 can be removed, cleaning liquid can be injected into the liquid storage container 50, and then the liquid storage container 50 can be connected to the laundry container 10 to inject cleaning liquid into the storage space 11 through the liquid storage container 50. In this way, even if the laundry container 10 is far from a water source such as a faucet, cleaning liquid can be injected into the storage space 11, and the cleaning device 100 can be washed at any location.

In one embodiment, the liquid storage container 50 is solidified with the laundry container 10, and after the injection of the cleaning liquid into the liquid storage container 50 is completed, the liquid inlet of the liquid storage container 50 is closed, and the water inlet and outlet channels 51 between the liquid storage container 50 and the laundry container 10 are opened, allowing the cleaning liquid to enter the laundry container 10 from the liquid storage container 50, ensuring leak-proofing between the liquid storage container 50 and the laundry container 10.

Referring to FIG. 11, in some embodiments, the external fluid includes a liquid, which enters the pulsator 20 via the fluid inlet assembly 30 to rotate the pulsator 20, and the fluid suction assembly 40 sucks the liquid in the storage space 11 to create a negative pressure in the storage space 11. The liquid sucked from the storage space 11 by the fluid suction assembly 40 is stored in the liquid storage container 50, and the liquid in the liquid storage container 50 can enter the storage space 11 via the fluid inlet assembly 30. In this way, the washing liquid can be reused, and waste can be reduced by returning the laundry detergent in the washing liquid to the storage space 11 to wash the items to be washed.

Referring to FIG. 12, in some embodiments, the laundry container 10 serves as the inner cylinder of the cleaning device 100, the liquid storage container serves as the outer cylinder of the cleaning device 100, and the inner cylinder is housed within the outer cylinder. The nesting structure of the inner cylinder and the outer cylinder is simple, and has the advantages of good leak resistance and high space utilization. The fluid suction assembly 40 includes a first passage 45 and a second passage 46. The first passage 45 communicates with the outside air, and the second passage 46 communicates with the outer cylinder. Before cleaning, the fluid suction assembly 40 opens the first passage 45 and closes the second passage 46 to remove the gas in the inner cylinder and place the inner cylinder in a negative pressure state. During cleaning, the liquid in the outer cylinder enters the inner cylinder under the action of negative pressure, and the fluid suction assembly 40 opens the second passage 46 and closes the first passage 45 to draw the liquid in the inner cylinder back to the outer cylinder, so that the inner cylinder always maintains a negative pressure difference with respect to the outer cylinder so that the liquid in the outer cylinder can continuously enter the inner cylinder.

Referring to FIG. 9, in some embodiments, the cleaning device 100 further includes a drainage unit 60. The drainage unit 60 connects the storage space 11 to the outside and is used to drain liquid within the storage space 11.

Referring to FIG. 9, in some embodiments, the cleaning device 100 further includes a heating unit 70 for heating the laundry container 10. After heating, the laundry container 10 increases the temperature of the liquid in the laundry container 10, so that stains are more easily and quickly dissolved in the liquid, and the cleaning power and cleaning efficiency of the cleaning device 100 are improved.

Here, the heating unit 70 may be a resistance wire, and the washing bin 10 may be made of metal to allow the washing bin 10 to heat up quickly. In one embodiment, the heating unit 70 is located at the bottom of the washing bin 10 for easy connection to a power source.

In some embodiments, the heating unit 70 is used to heat the fluid in the fluid inlet assembly 30 so that the fluid at a certain temperature can enter the interior of the laundry receptacle 10 from the fluid inlet assembly 30, dissolving the stains into liquid more easily and quickly, improving the cleaning power and cleaning efficiency of the cleaning device 100.

Referring to FIG. 1, in some embodiments, the inner diameter of the washing vessel 10 gradually increases from the side closer to the fluid inlet assembly 30 to the side closer to the fluid suction assembly 40. For example, in the embodiment shown in FIG. 1, the inner diameter of the washing vessel 10 gradually increases from bottom to top. The inner diameter of the washing vessel 10 is large on the side closer to the fluid suction assembly 40 and is small on the side closer to the fluid inlet assembly 30, i.e., the outlet diameter through which the fluid leaves the washing vessel 10 is larger than the inlet diameter through which the fluid enters the washing vessel 10. In this way, the washing efficiency can be improved by increasing the flow rate of the fluid in the washing vessel 10 and improving the flow efficiency of the fluid in the washing vessel 10, including the efficiency with which the fluid enters the washing vessel 10 and the efficiency with which the fluid is extracted from the washing vessel 10.

In summary, the pulsator 20 of the embodiment of the present application rotates under the propulsive action of the fluid flow, stirring the cleaning liquid in the washing container 10 to form turbulence, and the fluid that enters the washing container 10 collides with the cleaning liquid to generate air bubbles, and the turbulence and air bubbles remove stains, thereby improving the cleaning effect. Compared to a conventional pulsator 20 that is driven by a motor, the friction force generated when it comes into contact with the items being washed is smaller, so damage to the items being washed can be avoided.
