  FIG. 10 is a perspective view of the flap unit 28 including the opening / closing flap 24, and the flap unit 28 is mounted on the bottom plate 33 a of the base member 33.

  The flap unit 28 is configured by rotatably holding shaft portions 27 of a plurality of opening / closing flaps 24 on a frame 28a having a rectangular frame shape in plan view. Of the standing pieces 25, 26 of the opening / closing flap 24, the standing piece 26 on the side corresponding to the front side portion of the pest control device 11 has an arm portion 26 a that protrudes obliquely upward, unlike the other standing piece 25. ing. An interlocking shaft portion 26b is formed on the arm portion 26a. The interlocking shaft portions 26b of the plurality of opening / closing flaps 24 are rotatably connected via a connecting member 28b.

  The opening / closing flap 24 is rotated by driving an appropriate rotary actuator 28c such as a solenoid or a motor. A rotary shaft (not shown) of the rotary actuator 28 c is connected to one shaft portion 27 of one opening / closing flap 24 among the plurality of opening / closing flaps 24. In the illustrated example, since the three opening / closing flaps 24 are provided, the rotary shaft (not shown) of the rotary actuator 28c is coupled to the shaft portion 27 of the opening / closing flap 24 located in the middle. For this reason, the rotary actuator 28c is located at the most outwardly protruding portion on the front side in the housing 13.

  When the rotary actuator 28c rotates the shaft portion 27 of one opening / closing flap 24, the rotation is transmitted to the other opening / closing flaps 24 via the connecting members 28b, and all the opening / closing flaps 24 are simultaneously in the standing posture and the horizontal posture. It rotates 90 degrees forward and reverse. The rotary actuator 28c is driven and controlled via a control device (not shown) provided with a timer.

  In addition to the above, the pest control device 11 includes various devices for driving the heater 19, a temperature sensor for measuring the temperature of the medicine container 14, an operation switch, and the like, although illustration and detailed description are omitted.

  As shown in FIG. 11, a part of the rib 39 is notched on the inner surface of the back plate 35d of the storage rack 35 in the portion facing the heater 19 in the synthetic resin medicine storage section 14, that is, the reflection plate 29 is provided. Also good. Since the reflection plate 29 reflects the heat of the heater 19, the temperature of the medicine container 14 is increased and functions.

  The pest control device 11 configured as described above is used as follows.

  The cover member 41 on the back side is tilted or removed, the drug impregnated body 12 is stored in the storage rack 35, the drug storage unit 14 is closed, and the locking device 44 is used for locking.

  When the predetermined time of night is set as an operating time zone and the other time is set as a non-operating time zone by the control device, the pest control device 11 is driven according to the setting. During the non-operating time period, the fan 18 and the heater 19 are in an off state, and the rotary actuator 28c maintains a state in which the opening / closing flap 24 is horizontal and the bottom opening 22 is closed. When this is the operating time, the rotary actuator 28c is driven to put the opening / closing flap 24 in the vertical direction, and the bottom opening 22 is opened. Thereby, the medicine container 14 communicates with the outside through the bottom opening 22.

  The fan 18 and the heater 19 are also driven. By driving the fan 18, air in the pest control space is taken into the ventilation portion 17 from the air inlet 16 on the back of the upper end portion, and this air passes through the drug impregnation body 12 stored in the drug storage portion 14, that is, the storage rack 35. It moves downward, becomes medicine-containing air containing medicine, and moves from the exhaust port 15 to the exhaust passage space 20. The medicine-containing air that has entered the exhaust passage space 20 passes through the bottom opening 22 and diffuses from the bottom space Y through the notch 23 of the base member 33 in all directions.

  During operation, the temperature sensor controls to a preset temperature to create a more effective insecticidal environment and ensure safety.

  When the operation time elapses, the heater 19 and the fan 18 are stopped by the timer, and the rotary actuator 28c is driven to rotate the open / close flap 24 to a horizontal posture and close the bottom opening 22. Thereby, the communication between the medicine container 14 and the outside through the bottom opening 22 is blocked.

  Since the exhaust path space 20 forms an interval between the exhaust port 15 and the opening / closing flap 24, even when the drug is deposited on the exhaust port 15, the opening / closing operation of the opening / closing flap 24 is surely performed. The open / close flap 24 opens and closes without contacting the exhaust port 15, and also has a horizontal shaft portion 27 and a shaft portion that protrudes outward in the longitudinal direction of the open / close flap 24 and is located outside the region having the exhaust port 15. 27, it is difficult to cause troubles in the turning operation even if the medicine is dropped. For this reason, even if the medicine falls on the exhaust port 15 during the operation, the opening / closing operation of the opening / closing flap 24 can be ensured, and the bottom opening 22 is not closed or not opened by the automatic operation. Can be expected.

  Since the auxiliary plate member 21 having a through-hole 21c smaller than the size of the exhaust port 15 is detachably provided on the exhaust port 15, the dripping of the drug with respect to the exhaust port 15 can be suppressed also from this point.

  In addition, since the bottom opening 22 is one and a plurality of opening / closing flaps 24 are provided in parallel to the bottom opening 22, the height of the exhaust passage space 20 can be made relatively small, and the pest control device 11. Contributes to downsizing.

  As for the downsizing of the pest control device 11, the rotary actuator 28c of the flap unit 28 is positioned on the front side, and is positioned in the middle portion in the left and right direction that protrudes outward most. Can be measured.

  Since the side opening 32a is formed in the peripheral surface of the housing 13 and the cover member 41 provided with the storage rack 35 is detachably attached, operability such as attachment / detachment of the drug impregnated body 12 is good. In addition, since the rotation support portion 42 is formed at the lower end portion of the cover member 41, the storage rack 35 is tilted so as to be pulled out, and the medicine storage portion 14 is opened, so that a desired work can be performed.
