Abstract
The utility model relates to an electrical sound-wave mosquito-broom device, which belongs to the mosquito-broom device. The electrical mosquito-broom device is provided with a stable power supply which is connected with an electrical vibrating device through a switch; the output terminal of the electrical vibrating device is connected with an electrical vocalizing device; after being connected with the power supply, the electrical vibrating device of the electrical mosquito-broom device can create the ultrasonic with stated bandwidth sound wave, which provides two functions: one is to use the attenuation frequency spectrum signal with 2.6KHz just like the sound produced by the similar natural enemies of the mosquito to remove or threat the mosquito; the other function is to use the attenuation frequency spectrum signal with 21KHz to compel the mosquito loss control. The integrative function for the two sound wave signals are to keep the mosquito around the body away or fall in a faint; so the device is with the better mosquito-broom function, as well as favorable adaptability to the environment; because of the adoption of the display and stable-pressure electrical circuit principle, even if the battery scope changes greatly, the working performance of the electrical circuit is still stable.
Description
Technical field
The utility model relates to a kind of mosquito expelling equipment, particularly a kind of electroacoustic wave mosquito expelling equipment.
Background technology
The seventies in 20th century, the Japanese adopted the acoustic resonance principle, produce the electronic mosquito expelling worm device of forming by electronic devices and components, make mosquito can not certain area coverage near the electronic mosquito repellent place in, the people who is in the regional extent that electronic mosquito repellent controls can not be subjected to the attack of mosquito, reaches the purpose that prevents bite by mosquitos with this.Electronic mosquito repellent of the prior art mainly has two problems:
1, because the kind of mosquito is more, and the eigentone of itself flight changes with the region is different, and existing mosquito expelling equipment can only send a kind of ripple of fixed frequency, therefore can only drive the mosquito of this fixed frequency, and universality is poor.
2, the frequency of oscillation of electronic mosquito repellent and oscillation intensity change with battery electric quantity decline, the circuit working instability, oscilator drift is serious, control range was dwindled with the end that falls of battery electric quantity, frequency of oscillation after the drift has exceeded the frequency range of expelling mosquito, does not have the effect of expelling mosquito.
Summary of the invention
The purpose of this utility model is will solve that existing electronic mosquito repellent frequency of oscillation is single, circuit working is unstable and technical problem that can not expelling mosquito.
The purpose of this utility model is achieved in that this electronic mosquito repellent has a stabilized power source, and stabilized power source is connected with electro coupled oscillator by switch, and the output of electro coupled oscillator is connected with electronic acoustical generator.
Stabilized power source has a direct current power supply, and dc source is connected the minus earth of light emitting diode by switch, resistance (R5) with light emitting diode.
Electro coupled oscillator is made of resistance, electric capacity, triode, resistance (R1), (R2), (R3), (R4) are connected with resistance (R5) simultaneously, resistance (R1) is connected with electric capacity (C1) with the colelctor electrode of triode (Q1) simultaneously, and the grounded emitter of triode (Q1) also is connected with GND; Base stage is connected with resistance (R2) with electronic acoustical generator (Y) simultaneously, and electronic acoustical generator is connected the grounded emitter of triode with the colelctor electrode of triode (Q2) with resistance (R4) simultaneously; Base stage is connected with resistance (R3) with electric capacity (C1) simultaneously.
Electronic acoustical generator is piezoelectric patches or miniature loudspeaker or buzzer.
Beneficial effect: owing to adopted such scheme, after the electronic mosquito repellent power connection, electro coupled oscillator produces the sound wave-ultrasonic with certain bandwidth, bandwidth 1.9KHz-30KHz, and this signal makes sound wave that piezoelectric patches or buzzer send upper frequency near around the human body through power amplification.This signal has two kinds of functions, one utilizes the signal with attenuation spectrum about the 2.6KHz that the natural enemy of similar mosquito produces to drive and threaten mosquito, it two utilizes the signal that has attenuation spectrum about 21KHz to force the mosquito that flies person of modern times's body out of hand, the result of the comprehensive function of these two kinds of acoustic signals make around the human body mosquito away from and go or fall in a swoon.This electroacoustic wave mosquito expelling equipment adopts the natural enemy signal of mosquito, and the ultrasonic signal that resonance takes place with mosquito is combined as a whole, and produces good repelling effect, and relatively good to the adaptability of environment.Owing to adopt demonstration and voltage stabilizing to take into account the type circuit theory, even if the battery changes in amplitude is bigger, the service behaviour of circuit is still stable.Reached the purpose of this utility model.
