As a small household appliance product, the electric mosquito swatter can effectively eliminate mosquitoes by generating high voltage. Its working principle is to use the DC voltage output by the battery through the boost and voltage doubling device, and finally produce high voltage electricity up to 2000V or more in the metal grid. When mosquitoes come into contact with this high-voltage power grid, they will be stunned or killed by the current, so as to achieve the effect of insect eradication. Electric mosquito swatting is not only practical and convenient, but also safe and hygienic without chemical pollution, so it is widely welcomed. In addition, the electric mosquito bat also has a power protection switch, safe and reliable use, and environmental protection and energy saving, suitable for various environmental use.
