preface
Mosquito bites in summer are things that make everyone's head big, and when you get up the next day when you go to bed at night, your hands and feet are full of red spots, although mosquito coils, flower water, etc. can solve the problem to a certain extent, but the pungent smell of some people can not adapt to it, and it is not very convenient to use. The electric mosquito swatter was born, and it can kill the mosquito swarm with a few shakes, which is very convenient to use and can also relieve the hatred in the heart.
