Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is installed inside buildings, automobiles, trains, etc., or in lockers for storing clothing, small items, etc., to store and hold volatile chemical liquids such as air fresheners, etc. The present invention relates to a device for dispersing volatile chemical liquids, etc., which is capable of dissipating gas accompanied by a gas into a room, a car interior space, etc.

0002

2. Description of the Related Art Conventionally, this type of dissipation device has been constructed by opening packaging bags, boxes, bottles, etc. for air fresheners, etc., which are sold in a sealed manner, and leaving the unopened container in a desired location. There are known devices that emit a fragrance or the like into the interior of a car or the interior of a car. There is also a method in which a medium impregnated with a volatile chemical solution is placed in a container, and a piezoelectric diaphragm is attached inside the container to promote volatilization and guide upward dispersion, and air is blown by fan action. However, in such a dispersion device, the discharge opening of the container is usually opened to a large extent because it is used to further diffuse the aroma once released into the air. As a result, a large amount of air fresheners, etc. are naturally released, and the scent remains in the room for a long time.The indoor space, which should be comfortable, can instead become a place of disgust due to excessive fragrance release. There is. In addition, as a means to prevent such adverse effects, it is possible to install a switching device and have a structure that opens the discharge port only for a predetermined time, but it is also necessary to separately install a drive device, a timer, etc. to drive the switching device. , the problem is that the structure becomes complicated.

[0003] In view of this problem, the applicant of the present invention previously proposed a system in Japanese Patent Application No. 2-302656, which includes a cylinder and a piston that moves within the cylinder while receiving resistance from a liquid. We have proposed a volatile chemical dispersion device that is equipped with a timer device that also has the function of opening and closing a gas discharge port provided in the gas discharge port.

0004

[Problems to be Solved by the Invention] In normal conditions, this dispersion device closes the gas discharge port of the casing with a cylinder, and fills the inside with aromatic gas etc. evaporated from the volatile chemical solution. When dissipating, the cylinder is separated from the gas discharge port by a pressing member to open the gas discharge port.

However, especially when used at high temperatures, the interior of the casing becomes high pressure due to evaporation of aromatic gases, and even if the cylinder is pressed through the pressing member, the cylinder cannot be separated from the gas discharge port. may not be possible. In this case, since the gas discharge port does not open, the aromatic gas cannot be diffused to the outside.

[0006] Therefore, the present invention has a simple structure and can diffuse fragrance etc. only when necessary, and can almost completely prevent release of volatile chemical solution due to natural leakage after dispensing is stopped. It is an object of the present invention to provide a device for dispersing volatile chemical liquids, etc., which can easily open and close a gas discharge port.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the device for dispersing volatile chemical liquid, etc. of the present invention includes a housing having a gas discharge port formed at an arbitrary location on a peripheral wall portion, and a device disposed within the housing. a timer device holding casing having a gas discharge port formed in a wall portion on one end side and an approximately cylindrical shape with an opening at the other end; A piston rod having one end fixed to the inner lid member, a fixed piston fixed to the other end of the piston rod, and a piston rod having a rear end protruding from the gas discharge port of the casing. The fixed piston is housed inside and is slidably disposed, and a flange part that opens and closes the gas discharge port by contacting and separating from the wall on one end side of the casing, and a flange part that is perforated in the flange part. a cylinder having a valve hole for installing an auxiliary valve; a viscous liquid hermetically stored and held within the cylinder; and a valve hole provided in a flange of the cylinder, the cylinder having a valve hole for opening and closing the auxiliary valve; an auxiliary valve that is operated to open before the flange part separates from the wall part on the one end side of the casing, and after the flange part of the cylinder separates from the wall part on the one end side of the casing, the auxiliary valve A timer device is provided to allow a delayed return after a predetermined period of time, and a volatile chemical solution is housed therein, and is fixedly connected to the other end of the casing, and is supplied through a vent hole formed in the inner lid member. a storage container for a chemical solution or the like for evaporating an aromatic gas or the like into the casing; and a storage container that is exposed on the circumferential surface of the housing and is arranged so as to be able to come into contact with a part of the auxiliary valve of the timer device and the rear end of the cylinder. and a pressing member that presses the cylinder to open the gas discharge port of the casing after opening the auxiliary valve.

[0008]

[Operation] In this configuration, under normal conditions, the gas discharge port of the casing is closed by the flange formed on the cylinder of the timer device, so the aromatic gas of the volatile chemical solution is filled in the casing. .

On the other hand, when the pressing member is pressed, the auxiliary valve is first opened, and then the cylinder of the timer device is pressed. As a result, the gas discharge port of the casing is opened and at the same time, the cylinder slides. While the cylinder is slowly returning to its original position after a predetermined period of time, the aromatic gas and the like that have filled the casing are released from the gas discharge port of the housing to the outside of the housing.

[0010] When the cylinder is completely restored after a certain period of time, the gas discharge port of the casing is closed again.
The emission of aromatic gases, etc. stops.

[0011]

Further, 37 shown in FIG. 5 is a third spring, which is disposed between a flange portion 32a protruding from the cylinder 32 and an inner cover member 43 of the casing 4, which will be described later. The end side is the gas discharge port 4 of the casing 4
The cylinder 32 is pressed in a direction protruding from 1a, and the gas discharge port 41a is closed by the flange portion 32a. Note that the arrangement position is not particularly limited, and may be arranged, for example, within the cylinder 32, between the piston 31 and the bottom wall portion 32f of the cylinder 32.

As shown in FIG. 5, the casing 4 is formed into a cylindrical shape with a bottom, and has a wall portion (bottom wall portion) on one end side.
41 is provided with a gas discharge port 41a having a diameter larger than the diameter of the cylinder portion 32 of the timer device 3. In addition, a substantially cylindrical inner lid member 43 having a ventilation hole 43a and a female screw portion 43b for connecting a storage container 5, which will be described later, formed in the inner peripheral portion is fitted into the other end opening 42. Fixed.

This casing 4 holds the above-mentioned timer device 3 as follows. That is, the rear end side of the cylinder part 32 of the timer device 3 is inserted into the gas discharge port 41a, and in the normal state, the third spring member 37
A flange portion 32a protruding from the peripheral wall of the cylinder portion 32
is pressed against the bottom wall portion 41 of the casing 4, and the flange portion 3
2a holds the gas discharge port 41a so that it can be closed. Note that one end 30a of the piston rod 30 of the timer device 3 is fixed to the inner lid member 43 by screwing a bolt 44 into a tapped hole 30c.

As shown in FIG. 5, the storage container 5 can be filled with a volatile chemical solution, etc., and has a cylindrical storage section 51 with an opening at the top and a bottom. An inner lid 52 with a concave cross section to be fitted, and one end 53a of the inner lid 5

This storage container 5 is fixed to the casing 4 by screwing the male threaded part 51a formed on the upper part of the storage part 51 into the female threaded part 43b formed on the inner lid member 43 fixed to the casing 4 described above. Concatenated.

[0022] Therefore, the timer device 3, the casing 4
and the storage container 5 are all connected and arranged. Further, as shown in FIG. 4, the casing 4 is attached to the casing 4 by bolts 46 via mounting portions 45 formed protrudingly on the peripheral wall thereof.
It is connected and fixed to the lid member 21 of the housing 2. Therefore, as the lid member 21 is opened and closed, the timer device 3 and the storage container 5 are inserted into and removed from the main body 22 of the housing 2.

Reference numeral 7 denotes a fan, which, together with the motor 8 and battery 9, constitutes a forced dissipation means for forcibly dispersing the evaporated gas from the volatile chemical solution to the outside of the housing 2. As shown in FIGS. 1 and 3, this fan 7 has a shaft portion 7a.
and a blade portion 7b, and is connected to a gas discharge port 24 provided in the lid member 21 of the housing 2.
It is housed and held in a fan housing section 25 having a gas intake port 25b. Further, the shaft portion 7a is connected to the fan storage portion 25.
connected to a rotating shaft 8a of a motor 8 disposed below the
The structure is such that the fan 7 is rotated by the drive of the motor 8. Note that an external power source may be used as the drive source for the motor 8;
As in this embodiment, the structure may be driven by a battery 9.

Here, 26 is a partition plate disposed inside the housing 2, which separates the motor storage section 26a and the battery box 2.
6b, and has a structure capable of holding the motor 8 and battery 9. Further, this partition plate 26 is connected to the fan storage section 2.
5 and screws 27 (see FIG. 1), and like the timer device 3 and the like, when the cover member 21 is opened and closed, the motor 8 and battery 9 are inserted into the main body 22 together with the fan 7. It is a structure that can be removed or removed. Furthermore, this partition plate 26 has two insertion holes 26c,
26d is bored, and the casing 4 can be inserted therethrough and supported.

The device 1 for dispersing volatile chemical liquid, etc. of this embodiment having such a configuration operates as follows. First, the lid member 21 of the housing 2 is opened in the direction of the arrow shown in FIG. The lid member 21 is closed by screwing together.

In the normal state, the gas discharge port 41a of the casing 4 is elasticized by the third spring member 37 and is closed by the flange portion 32a of the cylinder 32, so that the volatile chemical liquid, etc. in the storage container 5 is released. , evaporates from the core member 53 and fills the casing 4 (see FIG. 5).

On the other hand, when one of the pressing members 6 is pressed, it slides on the outer periphery of the cylinder 32, and a part 63 of the pressing member 6 first comes into contact with the spring receiving member 34c of the auxiliary valve 34, and the valve body 34b
Open the valve (see Figure 2). As a result, the valve hole 32b provided in the flange portion 32a of the cylinder 32 is opened, so that the pressure inside the casing 4 is reduced. When the pressing member 6 is further pressed, the recess 6 of the pressing member 6
1 comes into contact with the rear end of the cylinder 32 of the timer device 3 and pushes the cylinder 32 down. At this time, according to this embodiment, the auxiliary valve 34 is opened in advance and the pressure inside the casing 4 is reduced, so that the cylinder 32 can be easily pushed down. When the cylinder 32 is pushed down, the flange portion 32a separates from the gas discharge port 41a as shown by the imaginary line in FIG. It will leak out.

As the cylinder 32 is pushed down, the piston 31 moves relatively inside the cylinder 32.
It moves in the direction of the bottom wall part 32f. At this time, viscous liquid 3
3 opens the valve member 31c of the piston 31 to flow from the first liquid chamber 32d to the second liquid chamber 32e mainly through the large-diameter liquid passage hole 31b, so that only small liquid resistance acts. Therefore, the cylinder 32 can be easily slid without applying a very large pressing force to the pressing member 6.

After pressing down the pressing member 6, when the pressing force is released, the cylinder 32 is returned to its original position by the third spring member 37. At this time, since the viscous liquid 33 attempts to flow from the second liquid chamber 32e into the first liquid chamber 32d, the valve member 31c of the piston 31 is operated to close. As a result, the large-diameter liquid passage hole 31b is connected to the valve member 31.
The viscous liquid 33 is blocked by the close contact of c.
Since the liquid flows into the first liquid chamber 32d through the liquid flow path 31e and the small-diameter liquid passage hole 31a, the return operation of the cylinder 32 is extremely slow. therefore,
Until the cylinder 32 returns, the gas discharge port 41a of the casing 4 is open, and the housing 2 is kept open for a predetermined time.
Aromatic gases etc. will flow out. On the other hand, after a predetermined period of time has elapsed, the flange portion 32a provided on the cylinder portion 32 of the timer device 3 closes the gas discharge port 41a of the casing 4, so that the gas dissipation to the outside of the casing 4 is stopped. Furthermore, when the pressing force of the pressing member 6 is released, the auxiliary valve 34 is also moved back by the second spring member 34d, so that the valve hole 32b is also closed. Note that the return time of the cylinder 31 can be freely adjusted by changing the diameter of the liquid passage hole 31a or the viscosity of the viscous liquid.

The aromatic gas etc. that leaked into the housing 2 are
Gas is sucked in from the gas intake port 25b of the fan storage section 25, and the gas is passed through the gas discharge pipe 25a by the fan 7 to the lid member 21.
The gas is discharged to the outside of the housing 2 from the gas discharge port 24 .

Note that the operation of the fan 7 is achieved by disposing a switch (not shown) that is linked to the movement of the pressing member 6 or the cylinder portion 32 of the timer device 3 pressed by the pressing member 6. When pressed down, motor 8 turns on,
If it is configured to turn off when the pressing member 6 returns, it can be operated only while the cylinder 32 continues its returning operation, that is, for a predetermined period of time. In this case, it goes without saying that the drive switch for the fan 7 may not be interlocked with the timer device 3, but may be configured to be turned on and off separately.

Furthermore, in the above description, only one of the pressing members 6 is pressed, but it goes without saying that two pressing members may be pressed down at the same time. According to this, for example, by filling each storage container 5 with a medicine having a different aroma, it is possible to diffuse a mixed scent.

When the volatile chemical liquid or the like is consumed and the storage container 5 needs to be replenished, the storage container 5 can be easily removed from the main body 22 by opening the housing 2 as described above. Or it can be installed. The same applies when it becomes necessary to replace the battery.

The device for dispersing volatile chemical liquid, etc. of the present invention is not limited to the above-described embodiments. For example, in the above embodiment, two storage containers 5 are provided, and a corresponding number of timer devices 3, casings 4, etc. are provided, but it is also possible to provide only one container. It is also possible to have a configuration in which storage containers of other types can be loaded. Further, in the above embodiment, the fan 7
, an embodiment using a forced dissipation means composed of a motor 8 and a battery 9 has been shown, but it goes without saying that the gas may be naturally dissipated from the gas discharge port of the housing 2 without providing a forced dissipation means. It is.

[0035]

According to the volatile chemical liquid dispersion device of the present invention, aromatic gas, etc. from the volatile chemical liquid storage container can be diffused to the outside simply by pressing the pressing member. Furthermore, the timer device is activated at the same time, allowing the aromatic gas, etc. to be diffused to the outside for only a predetermined period of time, and after the predetermined period of time has elapsed, the diffusion of the aromatic gas, etc. can be almost completely stopped. Therefore, the fragrance will not be excessively diffused into the indoor space or the like.

Furthermore, since a timer device that utilizes liquid resistance is used, power consumption is low and it can be used for a long period of time. Furthermore, since the structure is linked to the pressing member, there is no need to separately provide a switch for a timer device, and the structure is simple.

Furthermore, since the structure includes an auxiliary valve on the flange of the cylinder that closes the gas discharge port provided in the casing for holding the timer device, even if the pressure inside the casing is high, the cylinder can be easily closed. Can be operated open.
