Automatic mosquito-repelling device and method

Abstract

The invention relates to an automatic mosquito-repelling device and method. The device includes a voice recognition module, a driving control module and a sound-wave play module; the voice recognition module is used for receiving outside sound and converting the sound into an audio spectrum to analysis whether or not the audio spectrum is within the vibration frequency range of mosquito wings, a starting control signal is sent when the audio spectrum is within the frequency range, and an inhibiting control signal is sent when the audio spectrum is not within the frequency range; the driving control module is used for receiving the starting control signal or the inhibiting control signal sent by the voice recognition module, and achieves start and inhibition of the sound-wave play module; the sound-wave play module is used for playing voices with ultrasonic frequencies to repel mosquitoes, wherein the ultrasonic frequencies are within the most sensitive frequency range of mosquitoes. The automatic mosquito-repelling device can repel mosquitoes, is high in automation and intelligence, manual intervention is not needed, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of electronic control, and in particular relates to an automatic mosquito repelling device and method. Background technique [0002] The hot weather in summer is especially suitable for mosquito breeding. In addition to causing short-term pain and long-term itching to the skin, mosquitoes may also infect many blood diseases. There are many mosquito repelling methods in the prior art, and the most common ones are mosquito coils and spray insecticides. These medicaments are more or less harmful to human health, and open flame mosquito coils also have certain potential safety hazards. In order to overcome the above-mentioned defects, there are devices on the market that emit ultrasonic waves of a certain frequency to drive away mosquitoes, which are harmless to the human body, but most of these devices activate the ultrasonic generating device by manual buttons, resulting in the inability to activate the ultra...

There are many mosquito repelling methods in the prior art, the most common of which are mosquito coils and spray insecticides. These agents are more or less harmful to human health, and there are certain safety hazards in open flame mosquito coils.

In order to overcome the above-mentioned defects, there are devices on the market that emit ultrasonic waves of a certain frequency to drive away mosquitoes, which are harmless to the human body, but most of these devices activate the ultrasonic generating device by manual buttons, resulting in the inability to activate the ultrasonic generating device in time to drive away mosquitoes. Mosquitoes or forget to turn off after starting, resulting in waste of electricity and shortening the use time
