Problems solved by technology
[0002] Electric fan is a kind of heating equipment commonly used in winter. People can use electric fan for heating in colder weather in winter. Since the electric fan sold in the market must be connected to the power supply to be used, this limits the scope of use of the electric fan. Producing an electric heating fan with a battery can solve the above problems well. At the same time, in order to check the remaining power of the electric heating fan so that it can be charged in time when the power is insufficient, a charging fan that can display the remaining power can be produced. electric fan
