Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a deodorizing device used to eliminate bad odors so that they do not fill a closed room or the like.

Car cabins, washrooms, changing rooms, and the like can be filled with bad odors, so it is best to install a deodorizing device in advance to make them more comfortable. A variety of such deodorizing devices have been provided in the past, but especially in the case of a car, when the car is parked in the summer, the interior of the car may become abnormally hot. Even when the car is not parked, it can get quite hot unless the air conditioner is turned on. At such high temperatures, the deodorizing agent stored inside the deodorizing device evaporates abnormally, which not only causes discomfort but also shortens the life of the deodorizing agent.

Therefore, in view of the above-mentioned conventional drawbacks, the present invention has the following advantages:
A communication path means leading from the internal space of the case to the outside of the case is provided, and a hole leading to the outside of the case forming a part of the communication path means is deformed by the outside air temperature so that it is closed when the outside air temperature exceeds a predetermined value. When the ambient temperature reaches a certain value, a thermosensing element such as a bimetal that opens when the temperature is below a predetermined value is used to prevent the deodorant from evaporating to the outside. By making it adjustable, it is intended to provide a deodorizing device that suits the actual situation.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 and 2 show a first embodiment of the present invention, and reference numeral 1 denotes a case made of resin, and the case 1 consists of an upper case 1a and a lower case 1b. In the figure, both cases 1a and 1b are shown in a closed state, but the left end 1d can be opened like a shell using the right end resin hinge 1c in FIG. 2 as a fulcrum. Spaces 2 and 3 are formed inside both cases 1a and 1b, respectively, and the lower space 3 further includes a space 3a in which a deodorant 4 is stored and a space 3b in which a sliding lever 5 is installed. Both spaces 3a and 3b can communicate with each other via a communication hole 3c (however, in FIGS. 1 and 2, the communication hole 3c is closed by the opening/closing surface 5a of the sliding lever 5, and both spaces 3
a and 3b are not communicating).
Here, the vertical wall 1 in which the communication hole 3c is formed
A vertical wall 1f formed on the upper case 1a hangs down at a position facing the vertical wall 1a, and the upper surface of one vertical wall 1e and the lower surface of the other vertical wall 1f are in close contact with each other. The upper space 2 is provided with the deodorant 4 by the vertical wall 1f.
The space 2a where is stored and the bimetal 6 described later
It is divided into a space 2b in which a is installed.

In the space 2b, a bimetal 6 is fixed to the upper case 1a with screws 7 via a fixing member 8.

The bimetal 6 maintains a solid line state when the temperature is low, but when the surrounding temperature rises, it bends to a state like a two-dot chain line, and the hole 1 formed in the upper case 1a
It works to block g.

The sliding lever 5 is mounted in the space 3b, which is a part of the lower space 3, as described above. The sliding direction is the direction of the arrow in FIG. A lever portion 5b is attached to the sliding lever 5 so as to protrude to the outside, and a sealing member (not shown) is attached to the contact portion between the lever portion 5b and the lower case 1b to prevent the deodorizer inside. 4 is sealed to prevent it from leaking outside the case.

Note that the convex portion 9 formed in the upper case 1a so as to hang down from the upper case 1a is provided to guide the movement of the sliding lever 5 on its lower surface 9a, and is similar to the above. The lower surface 8a of the fixing member 8 is also provided to guide the lever 5.

In this configuration, the deodorant 4 in the space A (which is a space combining the space 2a in the upper case 1a and the space 3a in the lower case 1b) in which the deodorant 4 is stored disappears. If you want to replace the deodorant 4 with a new one, or add a completely new deodorant 4, open the left end 1d like a shell using the protrusion 1c on the right end in FIG. Store in space A. After storage, both the upper and lower cases 1a and 1b are assembled and sealed as shown in FIG. The stored deodorant 4 is emitted within the space A, but as shown in FIGS. It doesn't leak. Manually move the sliding lever 5 to the first position.
When it is slid in the direction of the arrow in the figure, the communication hole 3c opens and the deodorant 4 flows out through the hole 1g (assuming, of course, that the bimetal 6 is in the solid line state). Therefore, the opening amount of the communication hole 3c can be manually adjusted on the premise that the surrounding temperature does not exceed a certain value.

Generally, even if a sliding lever 5, which is a manual adjustment means, is installed, the user often leaves the lever 5 open. In addition, especially in the summer, the interior of a parked car becomes hot, and when the temperature exceeds a certain value, the bimetal 6 works and the second
The state shown by the two-dot chain line in the figure prevents the deodorant 4 from accidentally flowing out to the outside.

Next, a second embodiment of the present invention will be described based on FIGS. 3 to 7. In Figure 3, the symbol 2
is a case made of resin, and the case 21 is composed of an upper case 21a and a lower case 21b as in the previous embodiment. A space 22 is formed in the upper case 21a, and about three quarters of the entire circumference is covered by a peripheral wall 2 with a constant thickness.
3, and the remaining approximately one-quarter is a cutout recess 24. There are five linear standing walls 26 approximately at the center inside the ceiling plate portion 25 of the upper case 21a.
is formed, and closed annular standing walls 27,
28 is formed. The vertical walls 27 and 28 have straight sections 27a and 28a parallel to the straight vertical wall 26.
and curved portions 27b and 28b along the peripheral wall 23. A groove 29 is provided inside the peripheral wall 23 over the entire circumference (although, of course, it is not provided in the notch recess 24).

As shown in FIG. 4, the lower case 21b is formed with a peripheral wall 31 that has the same thickness as the peripheral wall 23 of the upper case 21a (FIG. 3) and has a slightly smaller diameter. A notch recess 32 having the same size as the above-mentioned notch recess 24 is formed. An elastic portion 37 formed independently of the peripheral wall 31 by four cuts 33, 34, 35, and 36 at two opposing locations on the peripheral wall 31,
There are 38. The elastic parts 37 and 38 are formed so that when the inner diameter part of the peripheral wall 23 of the upper case 21a is smoothly fitted to the outer diameter part of the peripheral wall 31, the elastic parts 37 and 38 bend inward in the radial direction. has been done. That is, since the small protrusions 39, 40, 41 are formed on the outside of the elastic parts 37, 38 and at another location on the peripheral wall 31, when the peripheral wall 23 of the upper case 21a is fitted, the peripheral wall The small protrusions 39, 40 are pushed inward by the inner diameter portion of 23, which causes the elastic portions 37, 38 to bend inward.

A bottom part 42 (FIG. 5) that protrudes downward is formed in the center of the lower case 21b, and five linear vertical walls are formed on the inside of the bottom part 42 and on the floor part 43, which are integrally formed with the lower case 21b. There are 44 (Figure 4). The vertical wall 44 is similar to the straight vertical wall 26 of the upper case 21a, and when both the upper and lower cases 21a and 21b are combined as shown in FIG.
6 and 44 are arranged to face each other.

On both sides of the five linear standing walls 44, there are standing walls 4.
4, tall vertical walls 45 and 46 are formed. The bottom and both ends of the vertical walls 45, 46 are integrally formed with the floor 43 and the peripheral wall 31, respectively, and the heights of the vertical walls 45, 46 are slightly lower than the height of the peripheral wall 31. Further, curved portions 45a, 45b, 46a, 46 are located near both ends of the vertical walls 45, 46.
b are formed, and these and the peripheral wall 31 form a space 47,
48 is formed, and bimetals 49 and 50 are installed in the spaces 47 and 48 (see FIG. 7, which is a sectional view). How to install: Bimetal 4
9 and 50 are fixed to the lower case 21b by screwing one end with screws 51 and 52.
Under normal conditions, the bimetals 49 and 50 are in the state shown by the solid line in FIG. 7, but when the ambient temperature exceeds a certain level, they bend as shown by the two-dot chain line, causing the lower case 21b to bend.
The holes 53 and 54 leading to the outside, which are drilled in the holes 53 and 54, are closed. Here, to describe the operating temperature of bimetals 49 and 50 as an example, they begin to warp at about 60°C.
Complete closure as shown by the two-dot chain line occurs at approximately 80°C.

The part with the largest diameter of the lower case 21b is the flange part 55. The collar portion 55 has an annular plane 55a parallel to the bottom surface 42a of the bottom portion 42 in FIG.
and an annular curved surface 55b perpendicular to the bottom surface 42a.
It consists of. The reason why the annular plane 55a is provided is that when the upper case 21a and the lower case 21b are assembled, the inner diameter part of the peripheral wall 23 presses and fits the three small protrusions 39, 40, 41, and the peripheral wall 2
3 descends at a certain speed, the peripheral wall 23
It is provided to stop the lower end surface 23a of the lower end surface 23a from descending, that is, to function as a stopper.

In FIG. 4, everything other than the bimetals 49 and 50 and the screws 51 and 52 is made of resin and integrally molded. Note that a space 56 is created in the center of the lower case 21b by the portion of the peripheral wall 31 where the small protrusion 41 is formed and the two vertical walls 45 and 46.
A deodorant 58 wrapped in a polyethylene bag 57 is placed on the five linear vertical walls 44 in the space 56 as shown in FIGS. 5 and 6.

The upper case 21a and the lower case 21b can be assembled and removed freely. When assembling, the inner diameter part of the peripheral wall 23 of the upper case 21a is fitted from above onto the outer diameter part of the peripheral wall 31 of the lower case 21b. Match. In this case, as described above, the inner diameter part of the peripheral wall 23 is connected to the three small protrusions 39, 40, 4 of the lower case 21b.
Descend while pressing 1 inward. Then, near the end of the descent, the small protrusions 39, 40, 41 touch the upper case 2.
It fits into the annular groove 29 of the upper case 21a, and almost at the same time, the lower end surface 23a of the peripheral end 23 of the upper case 21a comes into contact with the annular plane 55a as a stopper. In this assembled state, the upper case 21a
can be rotated about axis 0 (FIG. 6) with respect to the lower case 21b. That is, FIG. 5 shows the cutout recesses 24 and 3 of both cases 21a and 21b.
Although the cases 21a and 21b are shown in a completely aligned state, either one of the cases 21a and 21b can be rotated. When this rotation is made, the inner diameter portion and the outer diameter portion of both the peripheral walls 23 and 31 slide against each other, and the lower end 23a of the peripheral wall 23 and the flange portion 55
The annular plane 55a slides on the annular plane 55a.

In addition, when the notch recesses 24 and 32 are aligned as shown in FIG. 5, the vertical wall 2 of the upper case 21a
7, 28 and the vertical wall 45 of the lower case 21b,
The upper end surface of 46 abuts without any gap as shown in FIG. Therefore, a space B formed by the space 22 in the upper case 21a and the space 56 in the lower case 21b
(Fig. 5) is cut off from the spaces 47, 48 in which the bimetals 49, 50 are housed (however, the space B is communicated with the outside via the notch recesses 24, 32 in the state shown in Fig. 5). ing). This state as shown in FIG. 5 is the state when the deodorant 58 in a bag is inserted into the space B or when it is replaced, and once it is inserted, the upper case 21a is removed as described above.
Rotate around axis 0. As this amount of rotation,
When the upper case 21a is turned 180 degrees from the state shown in Fig. 5,
Since the standing wall 27 of the upper case 21a abuts and matches the standing wall 46 of the lower case 21b, and the other standing wall 28 matches the standing wall 45, the space B is cut off from the bimetal storage spaces 47 and 48 in the same way as above, and at the same time both notches are cut off. Since the recesses 24 and 32 do not match, it is also shut off from the outside (the state in which the upper case 21a is rotated 180 degrees from the state shown in FIG. 5 is defined as a "completely shut off state").

When the upper case 21a is rotated in either direction from the completely blocked state, the vertical walls 27, 4
6 and the standing walls 28, 45 are released. The degree of this contact release, more specifically, the degree of movement of the upper case 21a, varies from space B to space 4.
The amount of communication to 7 and 48 is determined. As long as the bimetals 49 and 50 are in the practical state shown in FIG. 7, the space B communicates with the outside via the spaces 47 and 48. In other words, from the completely cut-off state, the upper case 21a
The amount of communication of the space B to the outside can be adjusted by manually rotating the space B. Therefore, the amount of deodorizing agent released from the space B to the outside can be manually adjusted.

Next, regarding the action of the bimetals 49 and 50, apart from the amount of communication due to manual operation, the bimetals 49 and 50 act to close the holes 53 and 54 when the surrounding temperature exceeds a certain value, so they automatically close the holes 53 and 54. The amount of communication is controlled and the deodorant 28 is prevented from flowing out to the outside. The cases 1 and 21 in the two embodiments described above can be placed and used in various places such as the interior of a car, a study, or a changing room.

Both of the above embodiments use bimetal as the temperature sensing element, but are not limited to this.
The device may be modified as appropriate by using wax or shape memory alloy.

As described above, the present invention provides a deodorizing device comprising an upper case and a lower case that can be freely assembled and removed and have a space inside, and a deodorizer installed in this space. A communicating passage means is provided, and a hole communicating with the outside of the case, which forms a part of the communicating passage means, is deformed by outside air temperature so that it closes when the outside air temperature is above a predetermined value and opens when the outside air temperature is below a predetermined value. Since the deodorant emission amount control means having a heating element is provided, when the temperature around the deodorizing device reaches a certain value, it is possible to automatically shut off the volatilization of the deodorant to the outside. Therefore, even if the deodorizing device does not have a separate manual outflow control means, the outflow is automatically controlled, making it possible to prevent indoor odors caused by excessive outflow. Life shortening can be prevented. In addition, if a manual outflow adjustment means is provided in addition to the automatic outflow control means described above, the outflow amount can be adjusted either manually or automatically, further increasing indoor comfort. I can do it.
