Description

technical field [0001] The invention relates to an inflator used for pumping gas into tires and other inflated objects, in particular to a portable inflator which is small in size and easy to carry. Background technique [0002] A general air pump generally includes a pump, a head mounted on the pump, and an air nozzle connector with one end connected to the head. The gas nozzle connector is connected to the gas nozzle of the object to be inflated, and the compressed gas is generated by operating the pump, and then the gas is inflated into the object to be inflated through the head and the air delivery tube. [0003] Based on the consideration of portability, some pumps are designed to be small in size. Such as Image 6 The air pump shown in the prior art includes a cylinder A, a handle B, a head C, a chuck valve D and a crank E arranged on the head. When inflating, put the chuck air nozzle D on the inflatable nozzle 6 of the object to be inflated, and then pull the crank ...
