The effect of mosquito repellent fan is quite good. An electric mosquito-repellent incense is installed at a proper position on the shell of the original electric fan, and a mosquito-repellent sheet is placed on it. When the power supply is turned on, the electric mosquito repellent heats up, so that the mosquito repellent sheet heats up and the medicine spreads, thus achieving the effect of mosquito repellent. The motor and mosquito repellent of the electric fan are controlled by two independent power switches, so that the two functions of blowing and mosquito repellent can work simultaneously and separately, which is very effective and convenient to use.
