Insecticide belongs to inflammable and explosive materials, and the mosquito killing racket is composed of three layers of metal mesh, which can generate a voltage of up to 3000V instantly after being electrified.

　　Under normal circumstances, the indicator light in the middle of the electric pen will be on when the electric pen contacts the charged object and the finger touches the other end of the electric pen. But when the electric pen is close to the electrified mosquito killing racquet, the indicator light of the electric pen has been on. At this time, the distance between the electric pen and the mosquito killing racquet metal net is still three or four centimeters. With such high voltage, there is no place for mosquitoes to hide, and the danger also comes: when it touches some conductive objects of mosquitoes, it will generate electric sparks, which are dangerous to some extent.

　　After the mosquito swatter is charged with electricity, the metal head of the screwdriver touches the metal net of the mosquito swatter, and an electric spark is generated instantly. How powerful is such an electric spark? At this time, if the mosquito swatter meets a can of insecticide, the fire starts instantly.

　　Insecticidal aerosol contains some combustible components of lipids, which will produce open fire when encountering the spark generated by mosquito swatter. Its principle is similar to that of a lighter. The high-pressure arc of the lighter interacts with the metal head of the air jet nozzle to produce obvious bright light. At the same time, the combustible gas in the lighter is ejected to form an open fire.

　　If the insecticide is sprayed in a closed space, and then the mosquito swatter is used, the consequences will be more serious.

　　Only in this way can the mosquito swatter be used safely!

　　1. When it is on, do not touch the network surface by hand. Its instantaneous discharge may reach 2000V, and the safety voltage of human body is less than 36V.

　　2. Do not touch the grid surface when it is closed, because there is still charge between the two layers of metal grid to generate residual electricity, and it is easy to get electric shock when touching the positive and negative poles.

　　3. Do not beat, hit, burn, etc.

　　4. It can not be used in places where there may be flammable gas, flammable liquid and explosive dust.

　　5. Avoid using with insecticide and flower dew at the same time, which will cause electric spark and easy to burn.

　　6. If there are mosquito residues on the mesh, shake the racquet to make it fall off or clean it with a brush. Do not wash it with water to prevent short circuit.

　　7. Do not press the switch or the touch screen when charging.

　　8. The charging time shall not exceed 15 hours.

　　9. Keep away from children and avoid electric shock when children's fingers reach into the metal grid.

　　10. Do not continue to use when the metal mesh of mosquito swatter is damaged or deformed.
