Electric inflator

The utility model relates to an electric inflator, in particular to a high efficiency electric inflator with multiple cylinders, which comprises a power source which is connected with a first inflating device which comprises an electric motor, a transmission gear group and a piston type cylinder while the power source and the input port of the electric motor are linked by a conducting wire. The gear wheel on the shaft of the electric motor engages with the transmission gear wheel group. The transmission gear wheel group drives the piston type cylinder. The outlet of the cylinder is connected with the air-out device for inflating. The power source is at least connected with a second inflating device which is the same to the first inflating device while their cylinders work in with each other. The second inflating device is in parallel connection with the first inflating device. The advantages of the utility are that the efficiency of inflation is high, the time of inflating can be saved by half or more in comparison with a normal one-cylinder inflator, the needed effect of inflating can be made in a short time, and the functions of illumination and flashing are provided.
