Abstract
The utility model discloses a high pressure inflator which is composed of an inner air cylinder and an outer air cylinder, wherein an air inlet channel is formed between the inner air cylinder and the outer air cylinder. The upper part of the outer air cylinder is fixedly connected with a handle, and the lower part of the outer air cylinder is assembled with an outer cylinder cap with air inlet holes. A sealing plug is arranged on the inner air cylinder. A one-way control valve which controls the on-off of an air storage chamber and an air discharge chamber composed of the inner air cylinder and the outer air cylinder is arranged in the sealing plug. The lower part of the inner air cylinder is fixed on a base of which the middle part is provided with a transversal conduit, and the transversal conduit is respectively communicated with the air discharge chamber and an output pipe. A sealing ring of which the section forms a V shape is arranged between the sealing plug and the inner wall of the outer air cylinder. The high pressure inflator has the advantages of reasonable design, strong sealability and good inflating effect, can prevent the air from returning and can save time and power without fuel filling when used, so the high pressure inflator does not make the user smeary.
