Abstract

The invention provides a handheld high-tension flyswatter. The handheld high-tension flyswatter is technically characterized by comprising a 3V direct current source, a high-frequency oscillating circuit, a booster circuit, a triple voltage rectifier circuit, a high-tension net, and an operating state indicator circuit. Killing flies in physical ways are advocated to protect the environment, namely no chemicals harmful to human bodies and pollutive to environment, such as pyrethrum, various insecticides, flypaper and poison baits, are used to kill the flies. Using the chemicals are of certain effect but are of certain pollution to the environment, and are less easy to use for children, pregnant women or special populations sensitive to fly chemicals. According to the principle of killing flies by high-tension shock, the high-tension net on the flyswatter is used to kill the flies. The whole fly killing process is physical. Therefore, effectively preventing or controlling various epidemics, spread by flies, and environmental friendliness are achieved.
