Description

Technical Field

[0001] The utility model belongs to the technical field of air pumps, and in particular relates to an air pump. Background Art

[0002] An air pump, also known as an air inflator, an air pump, or an inflation pump, is a common air pump that works by the operation of a motor. When the motor is running, the valve of the communicating vessel is opened by the atmospheric pressure, and the gas enters the air cylinder. When air is inflated into the tire, the valve is closed by the air pressure in the air cylinder, and the gas enters the tire.

[0003] Now it is more common to use a motor drive mechanism to drive the piston assembly to move back and forth to achieve the inflation effect; this motor drive mechanism generally has a motor driving the outer wheel disk to rotate through a driving gear, and the outer gear disk drives the piston rod to make a linear reciprocating motion. The structural design of the driving gear and the outer wheel disk meshing and rotating on the outside leads to a larger overall space occupied, resulting in a larger overall pump volume, a less compact structure, taking up space, being inconvenient to carry, and having a certain amount of noise.

[0004] Therefore, the utility model designs an air pump. Utility Model Content
