Abstract

The invention discloses an air inflation device and an air inflation method. The air inflation device comprises a base; an upper cover, wherein a first cylinder body comprising a first compression chamber and a second compression chamber is arranged between the upper cover and the base, and the second compression chamber communicates with a first outer pipe; a switching valve, arranged in a ventilation cavity of the upper cover, wherein the ventilation chamber unidirectionally communicates with an air inflation channel arranged on the upper cover. Whether the compression chamber is connected with the air inflation channel or not can be controlled by adjusting different positions of the switching valve; the air inflation channel is directly connected with an inflated device so as to achievethe air inflation of the inflated device, so that the compression cavities communicating with the air inflation channel can be gradually reduced in the air inflation process, and a user can graduallyreduce the number of the compression cavities used for air inflation along with gradual increase of the air pressure in the inner air inflation device.

Description

Technical field [0001] The present invention relates to a technology in the field of inflatable pumps, and more specifically, to an inflatable device and an inflating method. Background technique [0002] The air pump (hand-drawn air cylinder) can be inflated in both directions, that is, the piston in the cylinder body can be inflated in both strokes of the upward movement and the downward movement. When the air pressure in the inflated device is high, it is difficult for the user to lift the inflatable handle to inflate the device during the upward movement stroke. With the existing inflator pump, the user cannot choose to inflate in the upward stroke or the downward stroke according to the situation. Summary of the invention [0003] In view of the problems in the prior art, the purpose of the present invention is to provide an inflator and an inflating method, which can be controlled by adjusting the different positions of the switching valve to control whether the compression...
