Abstract
The utility model relates to a mosquito repelling device. The utility model comprises a box body, a dry battery, wires, a switch, a frequency wall and a circuit board, the upper part of the box body is provided with a hole, the dry battery, the wires, the switch, the frequency wall and the circuit board are arranged in the box body, the circuit board is provided with an oscillator circuit, the circuit board is connected with a sound generator arranged in the box body, the oscillator circuit is composed of a resistor, a transistor and a capacitor, the resistor, the transistor and the capacitor are connect in series, the saw tooth waves generated by the oscillator when the current flows through the oscillator, the sound generator is driven by the saw tooth waves, the frequency of the sound waves generated by the sound generator and the frequency of the vibration of the wings of the mosquito generate resonance, and the mosquito can not fly close to the human body. The utility model has the advantages of low electric power consumption and good mosquito repelling effect.
Description
The utility model relates to a kind of people's daily necessities, especially is used for expelling mosquito to bite the mosquito expelling equipment of human body skin.
The mosquito expelling equipment of Xiao Shouing roughly is divided into two classes in the market, and a class is that the flavor gas that has that the burning mosquito-repellent incense produces comes mosquito expelling, and another kind of is that electronic blowing is thrown out mosquito or made it to be difficult for close.Though they all have the effect of mosquito repellent, but also exist weak point, the gas that produces as mosquito incense burning contains certain nuisance, and long-term the use can be influential to health, electronic blowing easily makes the human body flu of suffering from cold, the little effect that does not reach expelling mosquito again of blowing amount.
The purpose of this utility model is that a kind of mosquito expelling equipment will be provided, can not only expelling mosquito, and can not produce pernicious gas again influences health or wind-engaging and catches a cold and fall ill.
The purpose of this utility model is achieved in that a kind of mosquito expelling equipment, it comprise by a top have the dry cell, lead, switch of the box body in hole and interior installation thereof, wall and wiring board are formed frequently, its wiring board be provided with oscillating circuit and and box in the acoustical generator that is equipped with link.Oscillating circuit is organized R1 by electricity, R2, R3, R4, triode BG1, BG2 and capacitor C 1, C2 constitutes, its resistance R 1, R2, R3, the pin of R4 connects the positive pole of power supply, another pin of resistance R 1 connects the b utmost point of triode BG1, one pin of resistance R 2 connects the c utmost point of triode BG1, one pin of resistance R 3 connects the b utmost point of triode BG2 and a utmost point of capacitor C 1, one pin of resistance R 4 connects the C utmost point of triode BG2, triode BG1, the e utmost point of BG2 and the negative pole of acoustical generator are in parallel to join with power cathode, be connected in series capacitor C 1 between the C utmost point of triode BG1 and the b utmost point of BG2, be connected in series capacitor C 2 between the b utmost point of triode BG1 and the c utmost point of BG2, the c utmost point of the positive pole of acoustical generator and triode BG2 and a utmost point of capacitor C 2 link.Acoustical generator is a sound chip, and its diameter is 9.5-10.5mm, and thickness is 0.14-0.16mm.Power supply is a dry cell.After loading onto battery in the box and closing a switch, after lead UNICOM, the oscillator of electric current by forming by the resistance on the wiring board, triode and electric capacity, produce sawtooth waveforms, drive acoustical generator, send audible sound from the sound hole of box body, frequency is the 7800-7900 hertz, resonate with the mosquito wing frequency that flies, make mosquito reach the purpose of expelling mosquito near human body.
The utility model modern design, simple in structure, easy to assembly, volume is little, is easy to carry, and power consumption is few, and repelling effect is good, no noxious odor and can wind-engaging.
Below in conjunction with drawings and Examples the utility model is illustrated in detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is a circuit diagram of the present utility model.
