Description

Ultrasonic expelling parasite evil control device

The utility model relates to the control of insect device, particularly a kind of control device that utilizes ultrasonic expulsion insect.

In the hotel, some places that have grain in reserve such as kitchen, instrument warehousing storage, kitchen, wineshop, warehouse, market, family kitchen livestocks such as mouse, cockroach, cat, dog occur and eat food steathily through regular meeting, cause economic loss.The method of preventing and treating of Cai Yonging mainly was pharmaceutical chemistry poisoning, electrical network corral etc. in the past.But people find to adopt pharmaceutical chemistry to pollute the environment gradually, also can accidentally injure people and animals, use electrical network waste electric energy, also cause fire easily.So someone designs a kind of ultrasonic rat repellent, utilize the ultrasonic rat destruction, ultrasonic people ear is not heard, the people there is not influence, but animal can be heard and can run away because of the ultrasonic intense stimulus, a kind of animal only to the ultrasonic sensitivity of certain frequency, present ultrasonic rat repellent frequency spectrum is too narrow, insect to other is inoperative, can not be as the control of insect device of wide spectrum.

The purpose of this utility model is to overcome the above problems, and the ultrasonic expelling parasite evil of a kind of frequency-shift type control device is provided, and it can produce the ultrasonic of frequency spectrum broad, can exert an influence to mouse, cockroach, cat, dog, make it be difficult to stand, have to escape immediately, reached the purpose of pest control.

The purpose of this utility model is achieved in that

A kind of ultrasonic expelling parasite evil control device, in casing, be provided with the shift frequency supersonic generator, ultrasonic transducer and periphery circuit, it is characterized in that: described shift frequency supersonic generator mainly is made of integrated circuit die I C1, the pin 2 of IC1 is through capacitor C 1, resistance R 2 is connected with the pin 11 of IC1, the pin 7 of IC1 connects the earth potential end of power supply, the positive potential end of power supply is through commutation diode D2, resistance R 9, R8, LED is connected with the pin 14 of IC1, the pin 1 of IC1,13 all are connected with pin 14, the pin 11 of IC1 is through diode D1, capacitor C 5 is connected with the base stage of triode VT1, the colelctor electrode of VT1 is through capacitor C 3, ultrasonic transducer B is connected with the pin 8 of IC1, and the pin 9 of IC1 is through resistance R 1, capacitor C 1 is connected with the pin 2 of IC1; The pin 12 of IC1 is connected through the emitter stage of resistance R 5 with triode VT1.

The model of described integrated circuit die I C1 is LH0049C.

The utility model has following positive beneficial effect:

Pest control device of the present utility model can produce the ultrasonic of wide spectrum, except that effect to also playing expulsion to other insects around the grain depot such as cockroach, cat and dog etc. the mouse, therefore applied widely, can be widely used in places such as hotel, hotel, food warehouse, kitchen.Play the effect of pest control.And saves energy, free from environmental pollution, can not accidentally injure the people.

Now further specify in conjunction with the accompanying drawings:

Fig. 1 is an external form schematic diagram of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model.

Please refer to Fig. 1, Fig. 2, be provided with the shift frequency supersonic generator in the casing 1 of ultrasonic expelling parasite evil control device of the present utility model, ultrasonic transducer and periphery circuit, it is characterized in that: described shift frequency supersonic generator mainly is made of integrated circuit die I C1, the pin 2 of IC1 is through capacitor C 1, resistance R 2 is connected with the pin 11 of IC1, the pin 7 of IC1 connects the earth potential end of power supply, the positive potential end of power supply is through commutation diode D2, resistance R 9, R8, LED is connected with the pin 14 of IC1, the pin 1 of IC1,13 all are connected with pin 14, the pin 11 of IC1 is through diode D1, capacitor C 5 is connected with the base stage of triode VT1, the colelctor electrode of VT1 is through capacitor C 3, ultrasonic transducer B is connected with the pin 8 of IC1, and the pin 9 of IC1 is through resistance R 1, capacitor C 1 is connected with the pin 2 of IC1; The pin 12 of IC1 is connected through the emitter stage of resistance R 5 with triode VT1.
