The safe voltage that human body can withstand is only 36V. Will it hurt if human body accidentally touches the electric mosquito racket with 2200V working voltage? The electric mosquito racket is different from the high voltage electricity on the transmission line. It raises the voltage through the booster device. Although the voltage looks very high, the electric energy in it is very little. With the protection circuit, the electric current is very small, so it hardly harms the human body.

　　Electric mosquito racket can kill mosquitoes, mainly because it generates high voltage when working to form an electric field, which is attractive to small organisms such as mosquitoes. When mosquitoes are adsorbed to the electric mosquito racket, it is equivalent to a resistance, which causes a short circuit to the circuit inside, and the current will pass through it instantaneously. Such a weak current is lethal enough for mosquitoes, but there is no sense of contact with the human body, and generally qualified products will have internal protection circuits, which can protect the human body, so it will not cause harm.

　　Electric mosquito racket is a low-voltage power supply, similar to the cell phone charger commonly used by people, which is converted into high-frequency voltage by electronic circuit. Now the electric mosquito racket on the market is generally charged, safer than the power-on type, and generally does not occur danger. But it is also related to human condition. People with heart disease should be more careful when using it. If they accidentally get electric shock, they should turn to 120 for help in time.

　　In addition, when purchasing electric mosquito rackets, we should pay attention to the quality of products and select qualified products produced by regular manufacturers. Charged mosquito racket should not be used when connected to power supply. If the aging of components occurs, do not contact the human body when electrified. In order to ensure safety, new products should be replaced in time.
