Self-measurement-control mosquito expelling and killing device

Abstract

The invention discloses a self-measurement-control mosquito expelling and killing device which comprises a mosquito sound positioning assembly, an ultrasonic expelling assembly, a mosquito sucking and killing assembly and an assembly control module. The assembly control module is connected with the mosquito sound positioning assembly, the ultrasonic expelling assembly and the mosquito sucking and killing assembly. The mosquito sound positioning assembly comprises audio sensors, an operational amplifier module and an AD module which are sequentially connected. The assembly control module calculates the sound source position and the frequency and phase of a sound source through the different linear distances between at least two audio sensors in the mosquito sound positioning assembly and the sound source and drives the ultrasonic expelling assembly or the mosquito sucking and killing assembly to work according to the distance, frequency and phase information. When the ultrasonic expelling assembly works, the ultrasonic expelling assembly gives out same-phase or reverse-phase low-frequency modulation ultrasound wave signals or low-frequency signals with the same frequency as that of the sound source of mosquitoes. The self-measurement-control mosquito expelling and killing device can react on mosquitoes of different types and genders in different regions and reach the mosquitoes intelligently to achieve the optimal culling effect; the mosquitoes can be expelled or killed intelligently, efficiently and quickly through sound-light alarm.

Description

technical field [0001] The invention relates to a mosquito killer, in particular to a self-measurement and control mosquito repellent. Background technique [0002] Existing electric mosquito traps and mosquito suction devices all belong to passive waiting or manual operation in structure, so there is missed catch, which increases the probability of people being bitten by mosquitoes. Since there is no early warning and alarm function, this probability also makes The device lost its ability to meet user expectations, affecting its sales. [0003] The use of sound to repel mosquitoes (such as the ultrasonic mosquito repellent that simulates bats), due to the single sound frequency, the mosquito repellent effect is not long-lasting, and the sound energy and sound frequency are used to repel mosquitoes, the energy is small, and the effect is not obvious. [0004] The photocatalyst mosquito killer simulates human body information (breathing, body temperature, smell, etc.), combi...
