Intelligent ultrasonic mosquito dispelling method

Abstract

The invention discloses an intelligent ultrasonic mosquito dispelling method. According to the method, an electronic mosquito dispeller is adopted, and comprises an MCU which has an embedded memory and a timer, an ultrasonic buzzer, a driving circuit and a power supply circuit; after the electronic mosquito dispeller is powered on, the power supply circuit supplies power to the MCU and the ultrasonic buzzer; at first, the MCU is initialized through internal resetting; after the resetting is finished, the MCU randomly selects a set of ultrasonic frequency from various sets of default ultrasonic frequency saved in the MCU; through the driving circuit and the ultrasonic buzzer, the selected ultrasonic frequency is outputted; meanwhile, the MCU selects a set of running time from various sets of default running time saved in the MCU; after the ultrasonic buzzer starts to work, the internal timer of the MCU starts timing, and the accumulative running time is always compared with the time written into a saving module of the MCU; when the accumulative running time reaches the selected time, the current cycle is finished and the MCU enters the next round, that is, the MCU reselects ultrasonic frequency and running time.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an intelligent ultrasonic mosquito repelling method. Background technique [0002] The problem of mosquitoes is a problem faced by every family and individual. At present, the commonly used mosquito repellent methods cannot meet the requirements of safety, environmental protection, health, and timeliness. Mosquito coils and insecticides are slightly toxic, and mosquito repellent lamps are dangerous. Mosquito medicine has a pungent smell and has varying degrees of impact on the human body. At present, there are electronic mosquito repellents in the market, but according to the test, there are problems such as low mosquito repellent efficiency and short distance. At the same time, the sound frequency and time pattern of electronic mosquito repellents that are common in the market are relatively fixed, and the effect will deteriorate after long-term use.
