Abstract

The utility model provides an intelligent electronic mosquito and fly repelling and kill device by sound energy, which is composed of a mosquito-sound receiving circuit, a frequency selecting circuit, a control circuit, an oscillating circuit, an amplifying circuit and an acoustic-electric converting circuit, and the circuits are sequentially connected and are supplied with power by the same power source. The instrument can emit a sound wave which is equal to or is several times as great as the wing flapping frequency when mosquitoes and flies fly according to the received mosquito sound, resonance is produced, the flying rule and the physiological structure of mosquitoes and flies are damaged, and thus mosquitoes and flies are repelled and killed.

Description

Intelligent acoustic energy electronics drives mosquito and fly killer

The utility model relates to a kind of electronics and drives mosquito and fly killer.

Mosquitos and flies has much more harms than benefits to the mankind, and they are bitten people and animals, spread disease, the living environment that harassing and wrecking are human, be typically our frontier guard daytime on duty have all to wear mosquito-proof mask.The Great War of people mosquito is of long duration, people have taked various methods for eliminating mosquito, have original smoke fire burn, have modern improvement of genes, have electronics, medicine is arranged, can be described as by every possible means, but owing to be subjected to the restriction of factors such as cost and prior art level, effect is not very good.Through market survey and preliminary search, find no and close product and the document utilize acoustic energy to drive to wipe out the flies and mosquitoes.

The purpose of this utility model provides a kind of intelligent acoustic energy electronics and drives mosquito and fly killer, this instrument can be selected frequency according to the mosquito sound that receives, send and approximate or be several times as much as mosquitos and flies when flight wing and instigate the wing of the mosquitos and flies of the sound wave of frequency and flight to instigate frequency generation resonance, in case mosquitos and flies flies in the energy range of sound wave that instrument sends, promptly by sound wave institute resonance, rule and physiological structure when having destroyed mosquitos and flies flight, and then reach and drive the purpose that wipes out the flies and mosquitoes.

The technical solution of the utility model is such, design a kind of intelligent acoustic energy electronics and drive mosquito and fly killer, it is made up of shell and the circuit board that is arranged on inside, it is characterized in that comprising on the described circuit board: mosquito sound receiving circuit, frequency selection circuit, control circuit, oscillating circuit, amplifying circuit and electroacoustic change-over circuit, and order connects successively, and above-mentioned each circuit is powered by same power supply; Described mosquito sound receiving circuit is composed in series by microphone MIC and resistance R 1, the capacitor C of between microphone MIC and resistance R 1, drawing 1 with by adjustable resistance W1, capacitor C 1 is connected with the frequency selection circuit that frequency-selector IC1 forms, and then through adjustable resistance W2 and capacitor C 2 with by adjustable resistance W2, capacitor C 2, C3 is connected with the control circuit that low-frequency oscillator IC2 forms, again by adjustable resistance W3 and capacitor C 4 with by adjustable resistance W3, capacitor C 4, C5 is connected with the oscillating circuit that resonant oscillator IC3 forms, last again through resistance R 2 be connected with the amplifying circuit that triode Q1 forms by resistance R 2, the output of amplifying circuit connects electroacoustic transducer, and described electroacoustic transducer is a loudspeaker, piezoelectric patches CR or crystal current sonic transducer.

The utlity model has following advantage:

1, the principle advanced person is pollution-free to human body, and drive wipe out the flies and mosquitoes effective; Utilize the principle of object resonance, make the wing generation resonance of the mosquitos and flies of sound wave that instrument sends and flight, wipe out the flies and mosquitoes thereby drive.Chang Yong solid or liquid drive the medicine that wipes out the flies and mosquitoes, and convert gas to through electronic mosquito repellent, spread in indoorly, and long-term the use can be deposited in the human body, might injure human body.This device does not use medicine, thereby has avoided the issuable infringement of human body.

2, intelligent management; Can send corresponding sound wave according to the mosquito sound select frequency automatically that receives, utilize the object resonance principle, it is better to drive the effect that wipes out the flies and mosquitoes.

3, simple in structure, with low cost, it is convenient to implement; Utilize existing electronic technology and components and parts can implement fully.

Below in conjunction with drawings and Examples, further specify the utility model.

Fig. 1 is the circuit theory diagrams that intelligent acoustic energy electronics drives mosquito and fly killer;

Fig. 2 is the circuit diagram that intelligent acoustic energy electronics drives a kind of embodiment of mosquito and fly killer.

With reference to Fig. 1, intelligent acoustic energy electronic mosquito expelling fly device of the present utility model comprises: mosquito sound receiving circuit 1, frequency selection circuit 2, control circuit 3, oscillating circuit 4, amplifying circuit 5 and electroacoustic transducer 6, and connect successively, and by same power supply 7 power supplies.

The physical circuit design is with reference to Fig. 2.Microphone MIC, resistance R 1 are composed in series mosquito sound receiving circuit 1; Adjustable resistance W1, capacitor C 1 and frequency-selector IC1 form frequency selection circuit 2, and the capacitor C 1 of drawing between microphone MIC and resistance R 1 is connected with mosquito sound receiving circuit 1, and wherein adjustable resistance W1 sets the frequent rate of separating of frequency-selector IC1; Adjustable resistance W2, capacitor C 2, C3 and low-frequency oscillator IC2 form control circuit 3, are connected with frequency selection circuit 2 with capacitor C 2 through adjustable resistance W2, and wherein adjustable resistance W2 sets the operating frequency of low-frequency oscillator IC2; The oscillating circuit 4 that adjustable resistance W3, capacitor C 4, C5 and resonant oscillator IC3 form is connected with control circuit 3 with capacitor C 4 by adjustable resistance W3, and wherein adjustable resistance W3 sets the operating frequency of resonant oscillator IC3; Resistance R 2, triode Q1 form amplifying circuit 5, are connected with oscillating circuit 4 through resistance R 2; Amplifying circuit 5 connects electroacoustic transducer CR.IC1 is a kind of extensive cmos device, and it has mixed simulation and digital circuit unit, is specifically designed to audio decoder.The 8th pin output Gao Ping when IC1 receives the mosquito tone signal, make the low-frequency oscillator 4 pin set of IC2 composition with this high level, low-frequency oscillator work, operating frequency is at 20Hz/S, the output signal of IC2 is directly modulated the resonant oscillator of being made up of IC3, what IC3 exported is interrupted signal wave, can strengthen the effect that wipes out the flies and mosquitoes like this, can also economize on electricity, after the amplifier that IC3 output is made up of Q1 amplifies, by CR electroacoustic transducer output sound wave, remove the wing resonance with mosquitos and flies,, make it can't bite people and animals to destroy the flight rule of mosquitos and flies, and then destroyed the physiological structure of mosquitos and flies, reach and drive the purpose that wipes out the flies and mosquitoes.
