Description

Technical Field

[0001] The present application relates to the technical field of inflation devices, and in particular to an inflation device. Background Art

[0002] An air pump, also known as an air pump, inflator, or inflator, operates through the operation of a motor and is a type of inflation tool. The operating principle of an air pump is as follows: when the motor is running and pumping air, the valve of the connecting device is pushed open by atmospheric pressure, allowing air to enter the cylinder. When inflating the device to be inflated, the valve is closed by the air pressure within the cylinder, allowing air to enter the device. Air pumps are widely used in applications such as automobiles, motorcycles, bicycles, balls, paddleboards, and inflatable boats. Currently, commercially available air pumps generally suffer from poor heat dissipation, which reduces their service life and reduces the continuity of inflation. Utility Model Content
