Abstract
The utility model discloses a multipurpose inflator pump which comprises a support, an air pump motor is fixedly installed at the bottom of the support, a driven inner gear is rotationally arranged on the support through a bearing B, a driving gear rotating synchronously is installed at the output end of the top of the air pump motor, and the driving gear extends to the inner side of the driven inner gear. The driving gear and the driven inner gear are in meshing transmission, the driven inner gear is eccentrically provided with a driven gear connecting rod connecting shaft, and two air vents are designed between the three-way pipe and the cylinder sleeve and are matched with two movement check valves, so that the air flow of the air pump is increased, and the air inflation efficiency is improved; bearings are arranged at the mounting position of the driven inner gear and the support and the connecting shaft position of the connecting rod and the driven gear connecting rod, so that rotation is smoother, friction force is reduced, and energy loss is reduced. And the driven gear adopts internal teeth, has the advantage of low noise, and is in meshing transmission with the driving gear on the inner side, so that the space is reduced, and the structure distribution is more compact.
