Air inflation device

Abstract

The invention is applicable to the technical field of air inflation devices and provides an air inflation device convenient to operate during deflation. The air inflation device provided by the invention comprises an air bag and an air valve. The interior of the air bag is hollow and communicates with a valve cavity of the air valve. The air valve comprises an upper valve body, an upper valve pad,a key, a rotary disk, a lower valve body, a lower valve pad, a push part and a reset spring. The upper valve body is provided with an air inlet. The upper valve pad is arranged at the bottom of the upper valve body and used for sealing the air inlet and can be opened unidirectionally. The lower valve body is provided with an air outlet. The lower valve pad is arranged at the bottom of the lower valve body and used for sealing the air outlet and can be opened unidirectionally. The key and the rotary disk are arranged in the upper valve body in the axial direction. The push part is arranged between the upper valve pad and the lower valve pad. The reset spring is arranged between the push part and the lower valve body in an abutting mode. When the key is pressed to a preset travel, the rotary disk moves axially to push the upper valve pad open and push the lower valve pad open through the push part and meanwhile rotates circumferentially to get stuck on the upper valve body, and then continuous deflation is achieved.

Description

technical field [0001] The invention belongs to the technical field of inflators, in particular to an inflator with simple deflation operation. Background technique [0002] With more and more opportunities for people to go out to work or travel, many inflatable products, such as inflatable toys, swimming rings, inflatable pillows, inflatable mattresses, etc., are used more and more widely, and the air in the products will be emptied when not in use. It is convenient to carry and store in order to reduce the volume. When it needs to be used, it is necessary to inflate the product. The most primitive way of inflating is to blow air through the mouth of the person against the air inlet nozzle on the product, but this is time-consuming and laborious, and it is also unhygienic. If you use tools such as pumps to inflate, it will save time and effort, but it is more troublesome to carry tools such as pumps. [0003] In order to be able to inflate conveniently, there are currentl...
