Inflator with motor fixing ring

Abstract

An inflator with a motor fixing ring includes a casing, and a core and a motor installed in the casing. The motor is for driving the core to inflate an external object. The inflator further includes a motor fixing ring sheathed on the motor and clamped between the motor and the casing. An air gap is formed between an outer surface of the motor and an inner surface of the casing. During the use of the inflator, the motor fixing ring is sheathed on the motor, and the motor is installed into the casing, so that the motor fixing ring is clamped between the motor and the casing. A cooling fan of the inflator is provided for flowing air along the air gap to dissipate the heat generated by the motor, so as to improve the cooling efficiency of the motor and the performance of the inflator.
