Problems solved by technology

However, this kind of air pump can only inflate the airbag usually, but cannot deflate. When wanting to deflate, people usually can only squat on the ground, press the one-way valve of the air pump manually, make it open, and deflate , very inconvenient to operate
Even if the solenoid valve is used to automatically open the one-way valve, the air in the airbag cannot be completely discharged, and the airbag needs to be squeezed manually. For large inflatable products such as air beds, this deflation method is very laborious.

Abstract

An air exchange device for inflating air bag or releasing air from the air bag is composed of air pump and its base with air hole, and one-way valve for controlling if air can pass through the air hole. When an air bag is being inflated, the air inlet of air pump is communicated to the space outside the air bag and its air outlet is communicated to inside of air bag while the one-way valve is opened. When the air is being released from air bag, the air outlet of air pump is communicated with the space outside the air bage and its air inlet is communicated with inside of air bag while the one-way valve is opened.

Description

technical field [0001] The invention relates to a ventilation device, that is, a device for inflating and deflated air beds or other inflatable items. Background technique [0002] There are many inflatable articles on the market, such as air beds, etc., which are inflated by an inflator when in use. Generally, the inflation device includes an external air pump or a built-in air pump. The external air pump needs to be inflated manually, which is time-consuming and laborious, and has been gradually replaced by the air pump built in the air bag of the inflatable product. However, this kind of air pump can only inflate the airbag usually, but cannot deflate. When wanting to deflate, people usually can only squat on the ground, press the one-way valve of the air pump manually, make it open, and deflate , it is very inconvenient to operate. Even if the solenoid valve is used to automatically open the one-way valve, the air in the airbag cannot be completely discharged, and the...
