  The structure for adjusting the strength of the spring 34 is not limited to that shown in the embodiment.

Next, the operation of the pest control apparatus having the above configuration will be described.
First, the lid body 22 attached to the rear surface 3 of the casing 1 is removed, the medicine cartridge 25 is stored in the medicine storage portion 24 provided in the lid body 22, and then the lid body 22 is opened in the opening portion 21 of the rear surface 3. Is attached and locked with the key 23.

  In this pest control device, during the daytime non-operating period, the exhaust port 28 is closed by the shielding plate 29, and the electrical components such as the fan 12 are also turned off by the timer. The exhaust port closed state of the shielding plate 29 is maintained by the spring 34.

  Since the exhaust port 28 on the bottom surface 7 at the bottom of the drug chamber 10 is closed, no convection occurs in the drug chamber 10, so that the drug vaporized from the plate 26 accommodated in the drug chamber 10 Do not leak outside.

  When the night operating time comes, the timer is activated to energize the solenoid 32, the plunger 33 is attracted and moved by the electromagnet 36, and the shielding plate 29 engaged with the plunger 33 is moved to move the shielding. The opening 35 of the plate 29 and the exhaust port 28 on the bottom surface 7 coincide with each other, the closed exhaust port 28 opens, and the inside and outside of the drug chamber 10 communicate with each other.

  Electrical components such as the fan 12, the heater 19, and the temperature sensor 20 are activated by the timer.

  When the fan 12 is operated, external air is taken into the electrical equipment chamber 11 from the intake port 27, and the air reaches the medicine compartment 10 while cooling the electrical equipment in the electrical equipment chamber 11.

  The air in the medicine chamber 10 sent by the fan 12 passes between the plates 26 of the cartridge 25, and contains the insecticidal components vaporized from the plates 26 and is discharged to the outside from the exhaust port 28.

  At this time, the magnitude of the output of the heater 19 is adjusted based on the air temperature near the exhaust port measured by the temperature sensor 20 by the temperature controller of the electrical component and the appropriate temperature. Here, the appropriate temperature refers to a temperature within a certain range where the concentration of the insecticide component in the air can be an appropriate value effective for pest control.

In this state, the insect pests are exterminated by diffusing the insecticidal component in the kitchen for a predetermined time.
When the operation time elapses, the timer is activated to stop energization of the electrical components. When the energization of the solenoid 32 is stopped, the shielding plate 29 is urged by the spring 34 to move to a position where the exhaust port 28 is closed, and closes the exhaust port 28.

  In the embodiment, the strength of the spring 34 is adjustable, but the suction force of the solenoid 32 can be electrically adjusted.

  In other words, the electrical equipment chamber 11 can be provided with a driving force adjusting device that adjusts the strength of the solenoid 32.

  Although not shown, this driving force adjusting device rectifies and charges alternating current supplied from an external power source to direct current, applies a direct current voltage to the solenoid, and converts a commercial external power source into a low voltage, A rectification charging circuit, a constant voltage circuit whose output voltage can be adjusted, a time limit circuit for synchronizing with fan driving, and a driver for driving a solenoid are provided.

  The rectifying and charging circuit includes, for example, a rectifier that rectifies an alternating current that has been voltage-converted by a transformer to form a direct current, a capacitor that charges and smoothes the direct current, and a three-terminal IC provided with a radiator.

  The constant voltage circuit includes a three-terminal regulator having a Zener diode, a transistor, a fixed resistor, a variable resistor, a protection circuit, and the like, a radiator provided in the regulator, and a stabilizing capacitor, and is rectified and charged. The electric charge sufficiently stored in the capacitor of the circuit flows through the Zener diode by the voltage breakdown, and the output voltage can be adjusted according to the divided voltage of the fixed resistance and the variable resistance.

  The time circuit constitutes a part of a timer mounted on the electrical component, and synchronizes the operation of the solenoid and the operation of the fan in conjunction with the time circuit for driving the fan mounted on the electrical component. It is. In other words, when the pest control device is started to operate by the timer, when the time circuit detects the output current from the constant voltage circuit, a drive signal is sent to the time circuit that drives the fan, and the drive of the solenoid and the drive of the fan are substantially simultaneously performed. Can be executed.

  The driver applies a predetermined voltage to the solenoid. As a result, a voltage having a predetermined magnitude is applied to the solenoid.

  In the configuration as described above, the alternating current of the external commercial power source is converted into a predetermined voltage by the transformer, and is converted into a direct current and charged by the rectification charging circuit. Maintained. In this case, for example, when the solenoid has a rated voltage of 24 V, a resistance of 200 Ω, and a rated current of 120 mmA, when a voltage of 48 V is applied to the solenoid by a driver, a current of about 240 mmA flows to the solenoid and the driving force of the solenoid is almost doubled. Become. However, such voltage application is conducted for a short time in order to avoid burning.

  Here, by adjusting the voltage with a constant voltage circuit, the magnitude of the voltage applied to the solenoid changes, and the driving force of the solenoid can be made variable.

  According to the embodiment, the inside of the casing 1 is divided into the front and back by the partition wall 9, one of which is the drug chamber 10, the other is the electrical equipment chamber 11, and external air is introduced into the casing 1, Since the fan 12 that discharges from the electrical chamber 11 through the drug chamber 10 to the outside is provided, the height of the device can be kept low compared with the conventional configuration in which the electrical chamber is provided above, and a compact design can be achieved.
