Abstract

The utility model discloses a miniature inflator. The miniature inflator comprises a body, an air nozzle, a first cylinder group and a second cylinder group. When a user directly rotates the first cylinder group, the effect of transferring high-pressure and low-pressure inflating positions can be achieved by rotating the first cylinder group relative to the body. The miniature inflator has the advantages that the use is very simple and convenient, the problem that the traditional inflator needs operation of extra components in the transferring process, such as loss in mutual fastening of two extra seat bodies or loss of an extra transferring switch and the like; and the transfer to the high-pressure inflating position or the low-pressure inflating position can be achieved only by needing to operate the first cylinder group and enable the first cylinder group to rotate relative to the body.

Description

Mini inflating pump

Technical field
