Abstract

The utility model relates to an electric insect and rat expelling apparatus, which comprises a bistable multivibrator circuit, a frequency generating device based on a decade counter, an ultrasonic wave generator and an electromagnetic wave generating device. Alternate current signals are conveyed to the bistable multivibrator circuit through voltage reduction, current limiting and smoothing orderly, and then, the alternate current signals are input in the ultrasonic wave generator. Output signals at the other output end of the bistable multivibrator circuit is input in the decade counter, and generated ten kinds of square signals with different frequencies are input in the electromagnetic wave generating device through an output end of the decade counter. In this way, the electromagnetic wave generator is caused to generate electromagnetic wave with different frequencies and the electromagnetic wave and ultrasonic wave are act on insects and rats in common. Thereby, the expelling effect is improved.

Description

Electronic insect-dispelling mouse device

Technical field

The utility model relates to a kind of electronic insect-dispelling (mouse) device, particularly a kind of electromagnetic wave of changeable frequency and ultrasonic electronic insect-dispelling (mouse) device.

Background technology

Current expelling parasite (mouse) technology has a lot, and to drive the worm mouse comparatively general so that ultrasonic or electromagnetic wave to take place especially, but this series products mostly is the generation fixed frequency, overlong time, and the worm mouse can produce adaptability to fixing frequency wave, thereby dispersion effect is reduced.

The utility model content

The purpose of this utility model is to overcome the technical limitation of existing repellent, a kind of employing ultrasonic and electromagnetic wave combination are provided, produce frequency range is wider and frequency does not intermittently change electromagnetic wave and ultrasonic, reduce the worm mouse fixed frequency electromagnetism is involved the repellent that ultrasonic produces adaptive possibility.

In order to achieve the above object, ultrasonic electronic pest repelling device of the present utility model comprises a flop-over circuit, the frequency changer circuit based on decade counter that links to each other with described resonance circuit; A ultrasonic generator that links to each other with described resonance circuit, one with described frequency conversion rate output circuit to the electromagnetic wave generator that connects, and the LED indicating circuit that is used to indicate the each several part duty, ac supply signal is converted into the same frequency low-power level signal through the step-down limiting filter circuit, be converted into time square-wave signal through flop-over circuit again, input signal as ultrasonic generator, the output signal of another output of described oscillating circuit is converted into ten kinds of different frequency square-wave signals via decade counter, the change electromagnetic wave of frequency of ten kinds of frequency signal circulation change, the electromagnetic wave generating device that is attached thereto of control.

Owing to introduced this frequency changer circuit based on decade counter, the electromagnetic wave that electromagnetic wave generating device sends can in very large range not stop to change, and can reach better expelling parasite, repellent effect.In addition, the LED indicating circuit is used to indicate the working condition of circuit at different levels, and the working condition of insect rat expelling apparatus is come into plain view.

The utility model will be illustrated in conjunction with the accompanying drawings by preferred embodiment.

Description of drawings:

Fig. 1 is a circuit theory flow chart of the present utility model.

Fig. 2 is the circuit diagram of the utility model embodiment.

Embodiment:

Fig. 2 is a specific embodiment of the present utility model, in Fig. 2, the power supply line is welded in J1 on the circuit board, the J2 position, J1 is with C2 in parallel excessively and R20 and semiconductor diode D14 anode and pass through resistance R 1, link to each other with serial counter U1 input 10, U1 output 5 is by the input of R2 and time-base integrated circuit U3, and U3 output 3 is connected to buzzer U5.Another output 15 output pulse signals of serial counter are connected to the input 14 of decade counter U2 and the anode of LED D1, the output 3,2 of decade counter U2 respectively, 4,7 and 1,5,6,9 respectively with semiconductor diode D4, D5, D6, D7 and D8, D9, D10, the D11 anode links to each other, and the negative electrode of semiconductor diode all is connected to the input 5 of another time-base integrated circuit U6, and output 10 is connected to the LEDD3 anode by resistance R 4.The output 3 of time-base integrated circuit U6 is connected to optically-coupled U4 input 2, and the output 4 of optically-coupled links to each other with the control end 3 of controllable silicon Q2, and the terminal 1,2 of controllable silicon Q2 is connected to inductor D and power connection points J2 respectively, and inductor D terminal 1 directly links to each other with J1.

The repellent circuit working principle of the utility model embodiment is described in detail as follows, 200V/50Hz exchanges and is connected in J1 on the circuit board, the J2 position, the J1 line of starting to exchange fire, J2 connecting to neutral line, power supply is through C1, send into binary string linage-counter U1 input 10 as clock pulses Kclk after the R20 step-down current limliting, be converted into the time square wave through the binary string linage-counter and export the input 5 of 555 time-base integrated circuit U3 to from output 5, the supersonic oscillations frequency of U3 output output blazes abroad by the buzzer that is attached thereto.The magnitude of voltage of input 5 can control output end 3 frequency, when a voltage rise was high, the frequency of output 3 reduced, and then raise on the contrary, changed so repeatedly, produced the ultrasonic of frequency conversion rate.Another output 15 output setpoint frequency signals of binary string linage-counter U1 are to decade counter U2, decade counter is just pressed certain frequency time from Q0-Q4 and Q5-Q9 output voltage, cause each diode current flow, generate the frequency that a meeting changes with U6 simultaneously, this moment, basis set became circuit U 6 outputs can produce a variation voltage, when this voltage adds to the input 2 of optically-coupled U4, can make inner two-way silicon conducting, thereby make the variation of the control end generation road current flow angle of the controllable silicon Q2 that is attached thereto, trigger the conducting of Q2.The Q2 conducting makes the inductance of the series connection with it magnetic field that changes, thereby generates electromagnetic waves.
