Description

One-way valve type inflator pump air filter

Technical Field

The utility model relates to the technical field of air pumps, in particular to a one-way valve type air filter of an air pump.

Background

The inflator for the vehicle is also called an inflator, an inflator and an inflator pump, and works by the operation of an internal motor. The principle is that when the motor is operated and the air is pumped, the valve of the communicating vessel is flushed by the atmospheric pressure, the air enters the air cylinder, and when the air is pumped into the tire, the valve is closed by the air pressure in the air cylinder, the air enters the tire, and the principle of the atmospheric pressure is used for inflating the automobile tire, the rubber ball and the rubber boat.
