In summer, although many people use mosquito repellents to drive away mosquitoes, they do not know what the working principle of mosquito repellents is? What is the principle of outdoor mosquito repellents? In fact, most electronic mosquito repellents are based on bionic developed on the basis of scientific principles.
Animals and plants in nature are diverse, interdependent and mutually restrictive. Humans have created bionics by observing and studying the characteristics of animals and plants and using the principle of mutual growth and inhibition between them. It is a good application to use the volatilization of essential oils of natural plants to avoid mosquitoes.
After studying a lot of data, it has been shown that the most ruthless mosquito bites in summer are the female mosquitoes during pregnancy. At this time, the female mosquitoes will avoid the male mosquitoes. Using this feature, an electronic frequency conversion circuit is designed to make the mosquito repellent generate ultrasonic waves similar to the male mosquitoes flapping their wings. , to achieve the purpose of repelling female mosquitoes.
Based on these basic principles of biology and bionics, high-tech circuits are used to simulate the sound of male mosquitoes and dragonfly wings fluttering. At the same time, these two sounds are integrated into a special ultrasonic wave to make mosquitoes flee. Since the frequency of ultrasonic waves is constantly changing in a large range, it can adapt to various mosquitoes without causing “adaptability” and “immunity”, and does not harm the human body
