Description

[0001]
[Industrial application fields]
The present invention relates to an apparatus for evaporating drugs such as insecticides, bactericides, and fragrances into air in a stable gaseous state.
[0002]
[Prior art]
Commercial electric mosquito traps heat the drug-containing body to evaporate the drug as a gas and kill mosquitoes and the like. According to the above-mentioned electric mosquito catcher, since the duration is short, continuous use for a long time is impossible.
[0003]
On the other hand, Japanese Utility Model Laid-Open No. 7-87872 discloses that the medicine is continuously evaporated by impregnating the tape with the medicine and passing the tape while contacting the heating element. According to the above technique, continuous use over a long period of time is possible depending on the length of the tape and the passing speed of the tape. However, since the length of the tape is limited, it is necessary to supply a new tape when the used tape is finished. Moreover, the chemical | medical agent discharge | released in the air by a heat generating body diffuses with the natural air flow in a room | chamber interior. For this reason, the medicine is not uniformly distributed throughout the room, and the desired insecticidal effect cannot be obtained at many sites.
[0004]
OBJECT OF THE INVENTION
Accordingly, an object of the present invention is to enable the transpiration of the drug to be continued for a longer time and to allow the drug to act uniformly in the room.
[0005]
[Means for Solving the Invention]
Under the above object, the present invention includes a tape-shaped containing body (7) containing the drug (6), and the containing body (7) is wound and stored in the cassette case (13). by heating by Jo containing body (7) heater (8), the agent (6) as a gas, gaseous agents (6) a case transpiration opening (10) two evaporating from the (9) A transpiration unit (2), a motor-driven fan (3) that generates an air flow in the direction of diffusion of the gaseous medicine (6) at the transpiration port (10), and transpiration in operation for a predetermined integration time A controller (4) for switching the unit (2) to a standby transpiration unit (2) to operate, and a timer for supplying power to the motor (11) of the fan (3) and the controller (4) with an appropriate on / off cycle (5) is attached.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
1 and 2 show the external appearance of the chemical transpiration apparatus 1 of the present invention, and FIG. 3 shows a schematic configuration of the transpiration unit 2. Then, 4 two transpiration unit 2 illustrates an electrical control system of the fan 3 of the motor-driven.
[0007]
The chemical evaporation apparatus 1 is assembled by a box-shaped case 9 as a whole. The case 9 accommodates the transpiration unit 2, the controller 4, the timer 5 and the like inside, and supports the motor-driven fan 3 by the support 12 at the upper part.
[0008]
Transpiration unit 2 is provided two inside of the case 9, the agent 6 is diffused as a gas from the evaporation port 10 formed on the upper surface of the case 9. That is, the transpiration unit 2 is provided with a tape-like containing body 7 containing a solid or liquid state insecticide 6 such as an insecticide, a bactericidal agent or a fragrance inside the cassette case 13 in a wound state. While the containing body 7 is in contact with the heater 8, the medicine 6 is sublimated or vaporized by moving it at a predetermined speed by feed means such as a feed roller or a feed motor. Released as a gas.
[0009]
The moving speed of the containing body 7 is set to about 1 [cm / hr], and the heating temperature of the heater 8 is 100 to 300 [° C. ] Is set to a degree.
[0010]
The motor-driven fan 3 is located above the transpiration port 10, takes air from the back side, and generates an air flow in the diffusion direction on the front side, so that the gas rising from the transpiration port 10 on the lower front side The medicine 6 is put on the air flow and diffused indoors.
[0011]
The motors 11 of the two transpiration units 2 and the one fan 3 are controlled by a controller 4 common to them and a timer 5 as necessary. That is, the timer 5 is connected between the two power supply terminals 14 via the fuse 16, and the timer contact 15 and the controller 4 of the timer 5 are in parallel with the timer 5 in a serial connection state. In this way, it is connected to the power supply terminal 14. The motor 11 is connected to the controller 4 in parallel.
[0012]
The controller 4 accumulates the respective energization times for the two transpiration units 2, switches the transpiration unit 2 in operation at a predetermined integration time , and operates the transpiration unit 2 in standby , When the trouble signal S of the operating transpiration unit 2 is input, the standby transpiration unit 2 is operated instead of the operating transpiration unit 2.
[0013]
The timer 5 is attached to suppress excessive transpiration of the medicine 6, and the transpiration unit 2 and the motor 11 are intermittently operated by turning on and off the timer contact 15 at an appropriate on / off cycle .
[0014]
At the time of use, the user attaches, for example, a cassette case 13 for spraying insecticides to the two transpiration units 2, sets the moving speed of the containing body 7 and the temperature of the heater 8 to appropriate values, and the chemical transpiration apparatus 1. Is installed in an insecticidal space, for example, indoors, and then the controller 4 and the timer 5 are connected to the commercial power source 17. In this way, the timer 5 is repeatedly turned on and off in a predetermined cycle, for example, on 40 [minutes] and off 20 [minutes], thereby causing the controller 4 and the motor 11 of the fan 3 to operate periodically.
[0015]
First, the controller 4 operates one of the transpiration units 2 and accumulates the energization time, that is, the operation time during the operation period of the transpiration unit 2. When the integration time reaches a preset integration time, the controller 4 stops supplying power to one of the transpiration units 2 in operation, and supplies power to the other transpiration unit 2 instead. Make it work. If the continuous operation time of one transpiration unit 2 (one cassette case 13) is, for example, 300 [hours], the two transpiration units 2 can be continuously operated for 600 [hours].
[0016]
【The invention's effect】
In the present invention, a fan is provided near the transpiration port of the transpiration unit, and the vaporized chemical solution is uniformly diffused into the installation space of the chemical transpiration device by the air flow of the fan. The effect can be expected.
[0017]
In addition, if the two transpiration units are switched using the controller, they can be used continuously over a long period of time, so there is no need to frequently replace the drug impregnated body (cassette case). Maintenance management becomes easy.
[0018]
Moreover, since evaporation unit is intermittently operated at a predetermined off period, at the appropriate drug concentration, because the drug effect can be obtained continuously further extended period of time, it can be used as an apparatus for the drug transpiration such as warehouses.
