The electric mosquito swatter is a kind of small household appliances. The electronic high-voltage mosquito swatter is practical, convenient, effective in killing mosquitoes (flies or moths, etc.), has no chemical pollution, and is safe and hygienic. It is an indispensable tool for daily pest control and has become a best-selling small household appliance in summer.
Can the blue violet light of the electric mosquito swatter attract mosquitoes?
The principle of mosquito killing lamp is to lure mosquitoes through ultraviolet light waves or carbon dioxide, bionic attractants (generally containing lactic acid, sweat acid, stearic acid, compound amino acids and other ingredients that simulate human body odor), and then through high-voltage electric shock or air-drying , Let the mosquitoes die, the substances used in it are non-toxic to the human body, so the correct use of purple mosquito killer lamps is non-toxic. Generally, the wavelength of ultraviolet mosquito killer lamps is 365nm, which belongs to the UVA band with longer wavelengths.
The circuit of the electric mosquito swatter is mainly composed of three parts: a high-frequency oscillation circuit, a triple voltage rectification circuit and a high-voltage shock net DW. When the power switch SB is pressed, the high-frequency oscillator composed of the triode VT and the transformer T is energized to work, turning the 3V direct current into a high-frequency alternating current of about 18kHz, which is boosted to about 800V by T (discharge distance estimation), and then After diodes VD2~VD4 and capacitors C1~C3 triple voltage rectification, it is raised to about 2500V, and then added to the metal mesh DW of the mosquito swatter. When mosquitoes and flies touch the high-voltage power grid, the insect body will cause a short circuit in the power grid and will be shocked by electric current, electric arc, or corona, or electrocuted immediately.
