Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatically evaporating chemicals such as insecticides and disinfectants for indoor insecticide and disinfection. Because the insecticide and disinfectant are highly toxic to the human body, a certain amount of drug is automatically sprayed at midnight when there is no person in the room, and when a person enters the room, the drug evaporator is first closed. Then, the concentration of the drug in the room is reduced to such an extent that it does not adversely affect the human body.

[0002]

2. Description of the Related Art The conventional apparatus for opening and closing a chemical vaporizer has only one layer (for example, Japanese Patent Publication No. 24522/1996). In order to be in a state, the switchgear must be very perfect, which requires a high degree of precision in the switchgear, which is expensive and difficult to maintain due to the high degree of precision And other defects.

[0003] A conventional cartridge containing a plurality of drug plates (plates) (refer to 1996 Patent Publication No. 24522).
Is a cylindrical box having a rectangular parallelepiped, and provided with guides for arranging plates in parallel in the vertical direction (vertical direction) of the inner surface of the box. Then, when incorporating the plate into the cartridge, the upper lid of the cartridge is opened and the plate is introduced from above. For this reason, it is necessary to move the plate from the upper side of the cartridge over the entire length of the cartridge, so that it takes a long time to incorporate the plate, and when the plate is incorporated, a portion of the plate may be damaged by contact between the plate and the guide. Contact surface between the plates and the guides for the plates, since the guides must cover the entire longitudinal length of the box, i.e. substantially the entire length of the plates, in order to avoid damage or damage. However, there is a problem that the effective volatilization area on the plate is reduced and the volatilization rate of the drug in the plate is relatively slow due to the large contact surface.

[0004]

SUMMARY OF THE INVENTION The present invention has solved the above-mentioned problems by making the opening and closing device of the chemical evaporator simple and double, and by making the shape of the cartridge special.

[0005] The drug evaporator of the present invention is a double container type drug evaporator comprising an outer container and an inner container for accommodating a cartridge containing a drug plate;
The upper part has an air intake port opened and closed by a shutter, and the lower part has an air exhaust port opened and closed by a shutter. The inner container has a plurality of ventilation holes on each of an upper wall and a lower wall that can be opened and closed by a shutter of the inner container. And an interlocking type in which the shutter of the outer container and the shutter of the inner container are simultaneously opened and closed. Drug evaporator. Further, the cartridge of the present invention is a cartridge having a rectangular parallelepiped outer shape for housing a plurality of rectangular medicine plates; The box has a window for air circulation on the lower surface and side surfaces of the box, and the box has a detachable portion on the periphery of the upper surface of the box which can be fitted and detached from each other, and has a plurality of drug plates. A plurality of guides which can be inserted in parallel on the inner surface of the lower surface of the box, the attachment / detachment portion is composed of the same number of concave portions and convex portions, and one upper surface of the box is inverted downward and if necessary When the box is rotated horizontally and aligned with the other upper surface of the box, the same number of recesses and protrusions are fitted to each other, and the two boxes are combined to form a cartridge.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION An opening / closing door is provided on the front surface of an outer container of a drug evaporator of the present invention. Above the outer container, that is, above the inner container, an air inlet, a shutter for opening and closing the air inlet, an air filter, a blower (a blower motor and a blower fan), and possibly a suction heater are arranged. At the center of the outer container, an inner container for housing a cartridge containing a plurality of drug plates is arranged. An air outlet and a shutter for the air outlet are arranged below the outer container, that is, below the inner container. The outer container and the inner container have a substantially rectangular parallelepiped shape.

[0007] The inner container comprises two left and right side walls, an upper wall and a lower wall, a rear rear wall, and a front front wall. The upper and lower walls of the inner container are perforated by a plurality of ventilation holes.

The rear wall of the inner container may be located directly on the inner surface of the rear wall of the outer container or in front of the inner surface, may be integral with the rear wall of the outer container, or may not have the rear wall of the inner container. Any of them may be used. If the rear wall of the inner container does not exist, all the rear ends of both side walls of the inner container and all the rear ends of the upper wall and the lower wall are in close contact with the inner surface of the rear wall of the outer container. When the front door is closed, the rear wall is tightly pressed by light pressing and is surrounded by the close contact portion, and also functions as the rear wall of the inner container. In this close contact area,
An elastic body may be attached for easy adhesion.

The front wall of the inner container is replaced by the front door of the outer container when closing the inner container. When the front door is closed, both the side walls of the inner container and all the front ends of the upper and lower walls can be brought into close contact with the inner surface of the front door. An elastic body may be attached to the contact portion for easy contact.

In this way, the rear wall of the inner container can be replaced by the rear wall of the outer container and the front wall of the inner container can be replaced by the front door of the outer container. In this way, it is possible to save material on the rear and front walls of the inner container. Further, when the cartridge is stored in or taken out of the inner container, the inner container can be opened and closed only once. In addition, the inner container can be easily taken out of the outer container, and work and operation on the side surface, the upper surface, and the lower surface of the inner container are facilitated.

As mentioned above, the upper and lower walls of the inner container are
It has a plurality of ventilation holes. This vent hole is opened and closed by a shutter of a type that suppresses from the outer surface of the inner container, or (b) slides a slit belt type slit belt on the upper surface of the upper wall and the lower surface of the lower wall of the inner container. It can be opened and closed by moving it.

In the case of opening and closing by sliding and moving a slit belt type slit belt, the inner container can be reciprocated on the ventilation holes in close contact with the outer surfaces of the upper and lower walls. One or a series of two slit belts are provided. The slit belt is provided with a belt ventilation hole for releasing the above-mentioned ventilation hole. The slit belt is linked with the above-mentioned air intake port and the following air exhaust port shutter, so that all the shutters can be opened or closed at the same time. A slide connector for interlocking the operation of the slit belt and the shutter group is provided from one side surface of the inner container to the upper and lower portions of the outer container on the same side as the one side.

When the slit is closed, the slit belt is closed at a position where the slit is closed by the tension of a spring coil connected via a placket attached to one end of the slit belt. The pores are fixed so that they do not overlap the vents of the inner container at all. Since the slit belt is in close contact with the outer surface of the inner container by the tension of the spring, the vent hole of the inner container is completely closed.

When the slit belt is opened, the belt vent is overlapped with the vent of the inner container by a gear system via a placket attached to the end of the slit belt, by resisting the tension of the spring coil. It is moved to the position and fixed. At this time, the above-mentioned slide connector is linked via the gear system to move the other two shutters to the open position. Thus, by the signal delivery of the open position, the blower is started and the air is blown. The air taken in from the air inlet passes through the air filter, passes through the air hole in the upper wall of the inner container, evaporates the medicine from the medicine plate in the medicine plate cartridge in the inner container, and removes the medicine from the lower wall of the inner container. The air passes through the ventilation hole and is exhausted from the air exhaust port. Then, the evaporated drug exerts an insecticidal or disinfecting function in the room where the drug evaporator is placed.

After the vaporized drug has been exhausted from the drug evaporator for a predetermined period of time, the blower is stopped and the vent is closed. At this time, the gear system is released, and the slit belt returns to the closed position due to the tension of the spring.
By interlocking, the air intake and the air exhaust are closed.

[0016] The slit belt is closely attached to the upper outer surface and the lower outer surface of the inner container and is arranged on both sides and away from the surface. The belt is supported via a roll or a support whose surface is a fraction of a cylindrical smooth surface to move the belt away from and on both sides. Since it is not necessary to close the vents of the inner container except for the part that moves on the upper outer surface and the lower outer surface, the belt is generally a belt having no belt vents having substantially the same width as the belts on the upper outer surface and the lower outer surface. However, a connected body that can connect the end portions of the belt on the upper outer surface and the belt on the lower outer surface with equal traction force, for example, a plurality of linear, narrow band, or cylindrical shapes that are difficult to elongate by tension, such as a male screw shape They may be connected. It is possible to adjust the tension of the slit belt and the position of the belt ventilation hole by adjusting the length of the connecting body with a screw.

By using the slit belt for opening and closing the inner container, the slit belt is housed in the outer container, and as a result, damage to the slit belt due to impact or contact that may be received from the outside of the drug evaporator is prevented. Can be avoided.

The upper and lower walls of the inner container are usually slightly curved upwards or downwards to aid the close contact with the slit belt.

The slit belt on the side surface of the inner container is arranged so as to be separated from the side surface of the inner container as described above. The slit belt on the upper part of the side surface of the inner container is almost in contact with the inner surface of the side wall of the outer container, but the inner surface of the outer container does not hinder the smooth movement of the slit belt when opening or closing the ventilation hole. Away from Most of the air blown by this does not pass between the side walls of the inner container and the outer container, but passes through the vent of the inner container. Then, a substantially rectangular shielding plate is installed obliquely from slightly above almost both ends of the slit belt on the upper surface of the inner container to the side wall so that the blown air passes through the ventilation holes of the inner container more. Sometimes.

A chassis is mounted inside the inner container so that one or a plurality of rectangular parallelepiped cartridges (containing a plurality of drug plates) can be smoothly slid and stored or taken out. ing.

The material in or near the air for evaporating the medicine inside the outer container of the medicine evaporator of the present invention is formed by the air sucked from the air inlet and the evaporation of the medicine on the medicine plate. If it is possible to be heated in order to promote the heat generation, the air must not be deformed or deteriorated by the heated air. The material of the outer container and the inner container may be any material having a strength capable of achieving the above-mentioned function, and is made of, for example, stainless steel, plastic or wood. A part of the front door may be made of a transparent plastic such as PMMA so that the state of the inside of the inner container can be observed. The material of the shutters of the air intake port and the exhaust port is, for example, ABS. The material of the slit belt is a material that can be easily moved while closely contacting the upper surface and the outer surface of the inner container and does not expand even by a long-time pulling force of a spring coil, for example, a polyester film (thickness,
125 μm). The material of the chassis for accommodating the cartridge is a material suitable for being contained in the inner container and capable of forming an outer surface capable of easily accommodating the cartridge, for example, an ABS resin. The gear system (for example, consisting of a gear cam, a gear relay, a gear worm and a gear motor) for linking the slit belt, the air intake port, and the shutter for the exhaust port and the material of the slide connector are commonly used. It is made.

A cartridge for containing a plurality of rectangular medicine plates is composed of two identically shaped boxes having windows for air circulation on the lower surface and side surfaces and most of the upper surface being open.
The box has a detachable portion on the periphery of the upper surface of the box which can be fitted and detached from each other, and a plurality of guide groups including a plurality of guides into which a plurality of drug plates can be inserted in parallel. Hold on. The above-mentioned attachment / detachment part is composed of the same number of concave portions and convex portions, and the same number of concave portions and convex portions are fitted to each other when the one box is reversed by a half rotation to align the upper surface with the upper surface of the other box. Are combined to form a cartridge.

In the method according to the invention, the length of the guide does not extend over the entire length of the lower surface, but only over two to four short portions on the inner surface of the non-window portion of the lower surface. That is, the length of the guide is much shorter than the entire length of the lower surface of the cartridge, that is, substantially the entire length of the medicine plate. There is a gap (guide groove) for inserting the medicine plate between guides adjacent to the built-in medicine plate at right angles. The width of the guide groove may be slightly longer than the thickness of the medicine plate. The guide grooves between the guides are parallel, and a plurality of guides are arranged at equal intervals and parallel to one another in the vertical direction of the built-in drug plate. The number of equally spaced guide grooves corresponds to the maximum number of medicine plates that can be built in, and the number of guides is one greater than the number of guide grooves. Here, when a group consisting of guides one more than the number of guide grooves is defined as a guide group, the guide group includes at least two to four groups, and preferably three groups, in order to effectively fix the medicine plate.
It is arranged so as to be parallel to the medicine plate with a window on the lower surface between them. That is, a plurality of (the maximum is the number of guide grooves between the guides) drug plates are formed by two to four guide groups.
Fixed.

The area where the guide portion contacts the medicine plate is the product of the length of the guide and the height at which the medicine plate contacts the guide.
The height at which the guide comes into contact with the drug plate is almost independent of the length of the guide, so that the guide can be relatively short in spite of being significantly shorter. This significantly reduces the contact area,
This can reduce the decrease in the volatile area of the drug on the drug plate due to the contact. Since the height of the guide is significantly shorter than the entire length of the medicine plate, the introduction time of the medicine plate can be shortened.

The tip of the guide attached to the inner surface of the lower surface of the box is slightly narrower than the base attached to the inner surface of the lower surface so as to facilitate introduction of the medicine plate. That is, the gap between the tips of adjacent guides for introducing the medicine plate is wider at the tips than the gap between the roots of adjacent guides. This facilitates the introduction of the drug plate and reduces the time required for fixing.

When the medicine plate is built in the cartridge,
First, a predetermined number of drug plates are inserted into one of the boxes into the guide grooves. Then, when the other box is turned half a turn, the upper surface that is open is turned downward, and it is placed on one box and then pressed, the concave portion and the convex portion on the peripheral edge of the upper surface are fitted, and at the same time, the other The guide groove of the box also sandwiches the medicine plate. Thus, the medicine plate is stably fixed by the guides of both boxes. Thereby, the medicine plate can be easily fixed in the cartridge. The method of the present invention eliminates the need to introduce the medicine plate over the entire length of the box (approximately equivalent to the entire length of the medicine plate) as in the prior art, thereby reducing the introduction time for fixing the medicine plate between the guides. it can.

Windows on each outer surface of the cartridge provide good air flow and facilitate evaporation of the drug. A conventional cartridge (for example, described in Japanese Patent Publication No. 24522/1996) has an upper surface and a lower surface which correspond to a window, but has no side surface which corresponds to a window. The window of the cartridge of the present invention is also opened on the side surface to increase the flow of air, whereby the volatilization of the drug on the drug plate can be accelerated.

The material of the cartridge for incorporating the drug plate may be a material commonly used by those skilled in the art, for example, a thermoplastic plastic, for example, a PVC resin.
Preferably, the cartridge has a slippery outer surface so that it can be easily installed in the chassis described above. The cartridge consists of two boxes, as described above, the two parts being essentially the same in function and shape. By using the cartridge portion having the same shape, it is possible to reduce the number of types of parts constituting the cartridge to only one. Therefore, when the cartridge is manufactured by cast molding of a synthetic resin, only one kind of injection mold is required, and similarly, only one kind of box storage can be used. Cost savings for inventory can be saved.

The drug plate for impregnating a drug, for example a pesticide, is usually rectangular. The material of the drug plate is a porous material such as an open-cell plastic foam such as urethane foam, a non-woven fabric, a fiber aggregate, a sponge, etc., and any material that is not affected by the solvent of the insecticide can be used. If the drug plate material is not self-supporting, it is reinforced with a self-supporting material. The drug plate is impregnated with as concentrated a volatile pesticide solution as possible. The volatile insecticide is not particularly limited as long as it is volatile, and examples thereof include DDVP (dimethyl dichlorovinyl phosphate) and its derivatives, homologues, and the like. Particularly, those having an odor that insects do not dislike are preferable. In the impregnation, an emulsion or a solution dissolved in an organic solvent is generally impregnated.

The medicine exhausted from the medicine evaporator of the present invention kills and controls indoor pests, especially sanitary pests such as flies and cockroaches.

As described above, the medicine plate is inserted into the guide groove between the guide frames of one box of the cartridge, and then the upper surface of one box is aligned with the upper surface of the other box, and at the same time, the guide of the other box is inserted. The drug plate is aligned with the groove to form a cartridge containing the drug plate. If necessary, the cartridge is covered with a paper seal and stored. When the chemical vaporizer is stored in the cartridge, the paper seal is removed from the cartridge, and then the cartridge is stored in the chassis installed in the inner container.

After storing the cartridge in the chassis,
The front door of the outer container will be closed, at the same time the inner container will be closed. At this time, the air intake and exhaust ports of the outer container and the vent of the inner container are closed. When opening the vent hole for drug evaporation, if necessary, the air sucked from the air inlet of the outer container is heated by a heater installed at the upper part of the outer container. When the vent hole is opened for the vaporization of the medicine, the shutters of the intake port and the exhaust port are opened in conjunction therewith, and the intake air vaporizes the medicine on the medicine plate and is exhausted from the exhaust port of the outer container. At the scheduled time, the vent hole is closed, and in conjunction with that, the shutters of the intake port and the exhaust port are closed.

[0033]

The present invention will be described in more detail with reference to the following examples. The examples are not intended to limit the scope of the invention. Embodiments will be described with reference to the accompanying drawings. FIG. 1A shows an outline of the appearance of a medicine evaporator 1 provided with an inner container 3 of a type in which ventilation holes 16a and 16b are opened and closed by the transfer of a slit belt 7. FIG. 1A shows a state in which the chassis 19 for housing the cartridge 18 in the inner container 3 is not inserted. FIG. 1B shows a state before the front door 25 is closed when the chassis 19 is placed in the inner container shown in FIG. 1A and the cartridge 18 containing the medicine plate 24 shown in FIG. Indicates the status.

FIG. 2 shows the intake port 5 and the exhaust port 1 of the outer container 2.
A shutter 6 for opening and closing the shutter 7 (a shutter for the exhaust port 17 is not shown);
The positional relationship between a slit belt 7 for opening and closing a and 16b, ventilation holes 7a and 7b, and upper and lower slide connectors 8a and 8b for interlocking them is shown. In FIG. 2, the chassis 1 without the cartridge 18 is stored.
9 are described. In use, four cartridges 18, for example, the cartridge of FIG.

FIG. 3 shows the opening and closing of the ventilation holes 16a and 16b of the inner container 3 by the movement of the slit belt 7.
(A) shows the open state of the ventilation holes 16a and 16b. For example, in the upper wall portion, the ventilation hole 7a of the slit belt 7 overlaps with the ventilation hole 16a of the inner container 3, and in the lower wall portion, the ventilation hole 7b of the slit belt 7 overlaps with the ventilation hole 16b of the inner container 3. At this time, air passes. (B) Vent 1
6a and 16b show the closed state, and in the upper wall portion, the portion between the adjacent ventilation holes 7a of the slit belt 7 is the inner container 3
And the case where the portion between the adjacent vent holes 7b of the slit belt 7 overlaps with the vent hole 16b of the inner container 3 in the lower wall portion. At this time,
Air flow is shut off.

FIG. 4 shows one of the boxes 18a after the cartridge 18 is divided into two parts. The medicine plate 24 is introduced into a guide groove 20a which is a gap between the guides 20. In the case of the cartridge shown in FIG. 4, since the number of the guide grooves 20a is 5, a maximum of five cartridges can be built.
The number of guide groups having five guide grooves 20a that are parallel to each other at equal intervals is three. These guides are in window 2
3 are interposed. Since the length of the guide 20 in the direction parallel to the medicine plate is short, the length of the medicine plate in contact with the guide grooves 20a of the three guide groups, which is three times as large, is significantly shorter than the entire length. Furthermore, since the medicine plate 24 is introduced from above the guide 20, the introduction distance is short, the time required for introduction is shortened, and the distance that may be damaged by contact with the guide groove 20a during introduction is also short. The contact area between the guide groove 20a and the medicine plate 24 is also remarkably small. A small contact area increases the volatilization area, and thus increases the volatilization speed. When the medicine is applied to the entire surface of the medicine plate, the effective use rate of the medicine can be increased, and the amount of the medicine used to increase the predetermined effect can be reduced.

FIG. 5 shows a case where five medicine plates 24 are placed in the box 18 shown in FIG.
a, the upper surface of the further box 18b is turned downward, the lower surface is aligned with the upper surface of the box in FIG. 4, and the state of the cartridge 18 after the concave and convex portions are fitted is shown. Is shown. The cartridge 18 is covered and sealed by a sealing sheet and stored. When used, the sealing sheet is removed and stored in the chassis 19 in the inner container 3 of the chemical vaporizer 1 in FIG.

For example, four cartridges 18 containing the medicine plate 24 shown in FIG. 5 are housed in the chassis 19, and the front door 26 of the outer container 2 is closed. At this time, the intake port 5, the ventilation holes 16a and 16b, and the exhaust port 17 are closed.

When the gear motor 12 is started, the gear worm 13 and the gear cam 14 are interlocked by the engagement of the motor gear 10 and the gear relay 11. Bracket 2 belt 9
Is fixed to the tip of the slit belt 7 with screws or rivets, and a tip with pins a and b is attached to the lower end thereof. When the pin a on one side of the chip is inserted into the groove of the gear cam 14, the slit belt 7 is pulled through the chip and the bracket 2 belt 9 according to the rotation of the gear cam 14. The vent holes 7a of the slit belt correspond to the vent holes 16a of the inner container 3, the vent holes 7b correspond to the vent holes 16b of the inner container 3, and the vent holes 16a and 16b of the inner container 3 It is designed to open. A pin b on the surface of the slit belt 7 opposite to the pin a on one surface of the chip is inserted into a pin hole of the lever connector 26. On one surface of the lever connector 26, there are both pins with the rotation fulcrum of the lever connector 26 interposed therebetween. The pins are inserted into pin holes of the slide connector 8a, and the pins are inserted into pin holes of the slide connector 8b. In accordance with the rotation of the gear cam 14, the pin b on the chip moves downward, the lever connector 26 rotates about the fulcrum as a rotation center, and the slide connectors 8a and 8b move through the rotation of the lever connector 26, and the slide connector 8a , 8
The leading end of b pushes the opening lever of the shutter 6 (illustrated only above) to open the shutter 6.
That is, the gear cam 14 rotates by the activation of the gear motor 12, the slit belt 7 moves through the pin a, and the ventilation holes 16a and 16b of the inner container 3 are opened, and at the same time, the slide connector 8a through the pin b The intake port 5 and the exhaust port 17 are in an open state by the interlocking of the intake ports 5 and 8b.
Then, air is sucked in from an air inlet 5 by a blower (not shown) activated by the interlocking, passes through a filter (not shown), and passes through a slit belt vent of a slit belt 7 at an upper portion of the inner container 3. 7a and inner container vent 1
6a, the medicine in the medicine plate 24 is volatilized while passing through the medicine plate 24 in the cartridge 18 placed in the inner container 3, and the lower slit belt ventilation hole 7b and the inner container ventilation hole After passing through 16b, the air is exhausted from the exhaust port 17.

The air exhausted from the exhaust port 17 contains a chemical component and can kill indoor pests such as sanitary pests such as cockroaches.

Thus, when air is blown for a predetermined time set in advance, the slit belt 7 which has been opened due to resistance to the pulling force of the spring coil 15 is released from the dead center on the gear cam 14 by the interlocking operation of the gear motor 12. The vent 16a of the inner container is closed by the portion between the adjacent vents 7a of the slit belt 7, and the vent 16b of the inner container is closed to the adjacent vent of the slit belt 7. It is closed by the part between 7b. At the same time, slide connectors 8a and 8b
As a result, the intake port 5 and the exhaust port 17 are closed, and the movable opening / closing part in the inner container is double-closed.

[0042]

According to the first aspect of the present invention, the inner container is attached to the outer container of the drug evaporator, and the inner container is double-opened and closed, so that the hermetic seal is completed with a relatively simple structure. Now you can do it. Since double opening and closing can be performed simultaneously by the interlocking mechanism, switching between opening and closing can be performed by one operation. The invention described in claim 2 is
Since the ventilation hole of the inner container is opened and closed by the elastic slit belt, the inner container can be easily closed. Since the slit belt is protected by the outer container, the slit belt is hardly damaged by impact and / or contact from the outside of the drug evaporator. According to the third aspect of the present invention, since the rear wall and the front wall of the inner container can be used as a part of the container of the outer container, the material can be saved.

Since the cartridge according to the fourth aspect uses two boxes of the same shape, when the cartridge is manufactured by molding a synthetic resin, the type of the mold can be one.
Also, only one type of storage is needed. Thus, costs are saved. By providing windows on the entire outer surface of the cartridge, the air flow was facilitated and the volatilization speed was increased. Further, by using two boxes, the time for introducing the medicine plate into the guide groove can be reduced.

According to the fifth aspect of the present invention, in addition to the effect of the fourth aspect, by using two boxes,
The length of the guide in the direction parallel to the drug plate was significantly reduced.
As a result, the contact area between the guide and the medicine plate can be significantly reduced, the damage that may be caused by the contact of the surface of the medicine plate with the guide can be reduced, and the area for volatilizing the medicine can be increased. Since this increases the effective volatilization area ratio on the medicine plate, when the medicine is applied to the front surface of the medicine plate, it also increases the effective use rate of the medicine.
