Description

Technical Field

[0001] The utility model relates to the technical field of inflators, and particularly relates to a piston-type inflator. Background Art

[0002] An inflator, also known as an air compressor, a gas pump, or an inflator pump, is a common air pump that operates by the rotation of a motor. When the motor rotates and sucks air, the valve of the connector is pushed open by the atmospheric pressure, and the gas enters the air cylinder. When inflating a tire, the valve is closed by the air pressure in the air cylinder, and the gas enters the tire.

[0003] However, traditional air pumps have low flow rates, slow inflation speeds, large sizes, heavy weights, and are not convenient to carry. Traditional air pumps use single power supply and cannot be used after the battery runs out. Moreover, when inflating an inflatable product, the inflatable product cannot automatically stop inflating after being fully inflated, which easily causes damage to the inflatable product.
