Description

Technical Field

[0001] The utility model relates to the field of air pumps, in particular to a compact inflator pump. Background Art

[0002] An inflator pump is a device used to fill air into objects, usually for items that need to be inflated such as car tires, air beds, inflatable toys, etc. When the inflator pump works, it operates through the rotation of an internal motor. When the motor rotates, it drives a piston to reciprocate in a piston chamber. In existing inflator pumps, the pump body is often horizontally arranged on the side of the piston rod below the cylinder, and the end of the piston rod is driven to move circumferentially around the drive shaft of the pump body through a gear set, so as to drive the end of the piston rod to move repeatedly in the cylinder. However, this horizontal arrangement of the pump body relative to the cylinder and other components will make the horizontal size of the pump body relatively large, occupying a relatively large space when carried outdoors. At the same time, the relatively wide shell shape also makes it impossible for the user to effectively and stably hold the inflator pump with only one hand during the inflation operation, affecting the user experience. At the same time, existing inflator pumps often design air guide channels on other side walls of the pump shell different from the inflation port, and these air guide channels arranged on other side walls are affected to varying degrees by the user's hand holding the air pump and surrounding clothes during the operation of the inflator pump, which also affects the user's holding and operation of the air pump.
