Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for releasing a gradual and gradually released drug such as a fragrance.

[0002]

2. Description of the Related Art Generally, an aromatic agent is used by being installed in a room while being stored in a container, and the aromatic agent is gradually diffused from the opening of the container to maintain the aromaticity of the room. .

Since the fragrance is generally a sustained-release agent, the fragrance cannot be maintained for a certain period of time when the opening of the container is completely opened. Therefore, the opening area of the opening is appropriate. It is closed by a lid or the like having a gap formed therein.

[0004]

However, the conventional container of this type for storing the fragrance has some provisions for maintaining the fragrance for a certain period in that the opening of the container is not completely opened. However, the fragrance is continuously released from the opening of the container, and the amount of the release cannot be controlled, and once the opening opens, the fragrance effect gradually decreases with the passage of days. However, it was the current situation that the aromaticity could hardly be maintained after a certain period of time.

Therefore, in view of such a point, although a diffusion device for controlling the emission amount of the fragrance and maintaining the fragrance has been developed, the mechanism of the device is complicated and the manufacturing cost is high. There is a problem such as sticking, and the emission amount cannot be sufficiently controlled even with such a device. Therefore, the present situation is that no fragrance disperser that can be put to practical use has been developed yet.

The present invention has been made in order to solve such problems, and it is possible to control an amount of a sustained-release agent such as a fragrance and the like, which is necessary and necessary, according to the purpose and use. It is an object of the present invention to provide a device for releasing a sustained-release drug such as a fragrance which is capable of being released and is not complicated in structure and is compact.

[0007]

The present invention has been made as a solution to such a problem, and a means for solving the problem is a container for containing a sustained release drug such as a fragrance. A tank part 7, a pump mechanism for pumping up the sustained release drug stored in the storage tank part 7, and a release storage part 8 for storing the sustained release drug pumped up by the pump mechanism in an open state for release. Pump type container 3
Then, the pump mechanism of the pump-type container 3 is operated to supply the sustained-release drug in the storage tank unit 7 to the diffusion storage unit 8 in a predetermined amount, and the required amount of sustained release drug is supplied to the diffusion storage unit 8. An electromagnetic actuation body 4 for electromagnetically actuating the pump mechanism while controlling so as to store a drug is provided in a device for releasing a sustained-release drug such as an aromatic.

When the electromagnetic actuating body is actuated to actuate the pump mechanism of the pump-type container, the sustained-release drug in the storage tank portion is supplied to the diffusion storage portion by a predetermined amount and is required in the diffusion storage portion. Only the amount of the sustained release drug is stored, and the other sustained release drugs are maintained in the state of being stored in the storage tank. Therefore, only the required amount of the sustained release drug can be released when needed, and the released amount can also be controlled by the electromagnetic actuator.

The electromagnetic actuating body 4 is composed of, for example, an actuating body 4a having a solenoid and a movable piece 28 reciprocally attached to the operating body 4a, and the pump mechanism is reciprocatingly movable. An engaging piece 27 is formed on the movable portion, which is engaged with the movable piece 28 of the electromagnetic actuator 4.

With such a structure, when the movable piece 28 of the electromagnetic actuator 4 moves forward, the movable piece 28 presses the locking piece 27 of the movable portion of the pump mechanism, and accordingly, the movable portion of the pump mechanism. On the other hand, when the movable piece 28 is moved back, the pressing of the movable piece 28 against the locking piece 27 is released, and the movable portion of the pump mechanism is moved back accordingly.

The pump mechanism is, for example, a storage tank portion 7
A fixed cylinder (12) having a flow path communicating with each other through a hole (15), and a movable cylinder (13) having a flow path communicating with the inside of the fixed cylinder (12) through the hole (16) and reciprocating in the fixed cylinder (12). A coil spring 14 interposed between the bottom lower surface side of the movable cylinder 13 and the bottom upper surface side of the fixed cylinder 12, and a closed ball 17 for closing the hole 15 of the fixed cylinder 12 and the hole 16 of the movable cylinder 13 respectively. , 18 and.

In this case, for example, when the movable piece 28 is locked by the locking piece 27 of the movable portion having the movable barrel 13 and presses the movable portion, the movable barrel 13 moves forward to move the movable piece 28. The movable barrel 13 is configured to move back when the pressing of the movable portion is released.

The pump-type container 3 and the electromagnetic actuation body 4 are detachably attached to, for example, a cover body. Further, a fan 6 can be provided near the diffusion storage part 8 of the pump-type container 3.

An outer cylinder 26 made of synthetic resin is mounted on the upper part of the auxiliary cylinder 22. The lower end of the outer cylinder 26 is inserted inside the flange 22a of the auxiliary lid 22 to close the opening of the auxiliary lid 22. The outer cylinder 26 is fitted on the upper part of the movable cylinder 13. A locking piece 27 is provided so as to project outward at a substantially central portion of the outer cylinder 26. The movable piece 28 is externally fitted to the outer cylinder 26 on the upper surface side of the locking piece 27 so that the movable piece 28 of the electromagnetic drive member 4 can come into contact with the locking piece 27. The outer diameter of the locking piece 27 of the outer cylinder 26 is formed to be larger than the diameter of the opening of the auxiliary lid 22, and the locking piece 27 opens the auxiliary lid 22 when the outer cylinder 26 descends. Flange 22a at the peripheral edge
It is configured to be locked on the upper surface side of the.

A locking piece 29, which is locked to the lower surface side of the flange portion 22a of the auxiliary lid 22, is provided at the approximate center of the movable cylinder 13 so as to project outward. The upper part 13 of the movable cylinder 13 above the locking piece 29

Is configured to be able to contact the inner surface of the. As a result, the movable cylinder 13 can move up and down with respect to the fixed cylinder 12.

A slope 8a is formed substantially in the center of the diffusion storage 8, and one side (the left side in FIGS. 5 and 6) of the slope 8a is formed as a bottom deep part 8b and the other side of the slope 8a. The side (right side in FIGS. 5 and 6) is formed as a shallow bottom portion 8c.
The attachment hole 21 into which the injection plug 20 is inserted is formed in the shallow bottom portion 8c of the diffusion storage portion 8. The diffusion storage part 8 is formed in a saucer shape as a whole.

The electromagnetic actuator 4 is housed in a cover 30 arranged on the side of the pump-type container 3 (on the right side of FIGS. 3 and 4), the outer side of which is made of synthetic resin and the inner side of which is made of synthetic resin. It is composed of an actuation body 4a having a solenoid and a movable piece 28 fitted onto the outer cylinder 26.

A battery 5 as a drive source for driving the electromagnetic actuator 4 is arranged below the pump-type container 3 and the electromagnetic actuator 4. The battery 5 is held by a pair of left and right battery holders 5a and 5b as shown in FIGS.

The fan 6 is arranged above the diffusion storage portion 8 of the pump type container 3, and a fan guide 31 is provided around the fan 6. On the side surface side of the lower cover body 2, a plurality of diffusion holes 32 for diffusing the fragrance are formed.

The fragrance diffuser as described above is installed in a room or the like and is used. To operate the fragrance spreader, a switch (not shown) is turned ON and electromagnetically driven. When the body 4 is driven, the movable piece 28 of the electromagnetic drive body 4 reciprocates up and down, thereby operating the pump mechanism of the pump-type container 3.

That is, when the movable piece 28 moves downward as shown in FIG. 7, the outer cylinder 26 which is in contact with the movable piece 28.
The locking piece 27 of is pushed down, whereby the outer cylinder 26 moves downward. When the outer cylinder 26 moves downward,
The locking piece 29 of the movable cylinder 13 that locks the lower end of 26 is the outer cylinder.
It is pushed down by the lower end of 26, so that the movable barrel 13
Moves downwards. At the same time, the coil spring 14 is in a contracted state.

When the movable cylinder 13 moves downward in this way,
The speed of the movable cylinder 13 accompanying the forward movement and the closed ball that floats for a moment
There is a difference in the speeds of the movable cylinders 13 and, as a result, the bottom of the movable cylinder 13 and the closing ball 18 are separated from each other, and the movable cylinder 13 that is closed by the closing ball 18
The hole 16 at the bottom of the is opened, and as a result, the fragrance flows into the movable cylinder 13 through the hole 16. The fragrance that has flowed in through the hole 16 rises in the movable cylinder 13 and flows into the diffusion storage section 8 through the slit 19 of the injection plug 20. In this case, the locking piece 27 of the outer cylinder 26 is locked to the upper surface of the flange 22a of the auxiliary lid 22 to prohibit the outer cylinder 26 from moving further downward, and thus the movable cylinder 13 also moves. As a result, it is prohibited to move downward.

On the other hand, when the pressing force of the movable piece 28 of the electromagnetic actuator 4 is released, the elastic force of the contracted coil spring 14 acts to urge the coil spring 14 upward so that the coil spring 14 can move. The cylinder 13 is pushed upward, and the diffusion storage part 8 is biased to its original position accordingly.

At this time, the bottom of the fixed cylinder 12 is pressed by the fluid that is about to flow into the fixed cylinder 12 from the storage tank portion 7 through the hole 15, and the closed ball 17 is temporarily pushed up. As a result, the hole 15 at the bottom of the fixed barrel 12 that has been closed by the closed ball 17 becomes open, and as a result, the fragrance flows into the fixed barrel 12 through the hole 15. Hole
After the fragrance has flowed in from 15, the closed ball 17 falls to the position of the hole 15 of the fixed cylinder 12 by its own weight and again the hole 15 of the fixed cylinder 12.
Is blocked, whereby the fragrance that has flowed into the fixed barrel 12 is prevented from flowing back to the outside of the fixed barrel 12.

Further, the movable barrel 13 returns to the upper side, but it is a closed ball.
18 falls to the position of the hole 16 of the movable cylinder 13 by its own weight and closes the hole 16 again. As a result, the fragrance that has flowed into the movable cylinder 13 is prevented from flowing back to the outside of the movable cylinder 13.

When the electromagnetic actuating member 4 is actuated as described above to alternately press and depress the movable piece 28 against the locking piece 27 of the outer cylinder 26, the fragrance is fixed from the storage tank portion 9. Although it flows into the cylinder 12 and further flows from the fixed cylinder 12 into the movable cylinder 13, its backflow is prevented,
The aromatic substance rises in the fixed cylinder 12 and the movable cylinder 13 and is intermittently pumped up into the diffusion storage section 8.
