Air valve device

Abstract

An air valve is composed of shell, a fan and a motor. Said shell has a first and a second air holes, an airflow chamber communicated to said two air holes, a flow guide part between two air holes andcommunicated to said airflow chamber, and a barrier in the airflow chamber between two air holes. Said fan is in said airflow chamber between two air holes. Said motor is used to drive the fan.

Description

【Technical field】 [0001] The invention relates to a gas valve device. 【Background technique】 [0002] Because general users often hope that the items they use can function normally in the use state, and can have the smallest occupied volume in the non-use state, or when they will not be used temporarily, so as to facilitate the user's life. Packing, such as inflatable beds, inflatable boats, swimming rings, etc., because these inflatable items must be filled with air to occupy a large volume when they are used, so the user will basically release the gas inside the item after using the item. Add to favorites. In addition, because these items must be filled with gas before they can be used, and can only be stored after the gas is released, the faster and easier the filling and deflation process, the better. However, the requirements and emphasis of some existing charging and deflation motors are nothing more than making the motor rotate as fast as possible, or replacing it w...

AI Technical Summary

Problems solved by technology

However, the requirements and emphasis of some existing charging and deflation motors are nothing more than making the motor rotate as fast as possible, or replacing it with a motor of a larger size, but this is often reflected in the cost of the item first. In fact, generally speaking, the higher the efficiency and the higher the speed of the motor, the higher the price will be. The reason for this is that the fan generally used to drive the motor is nothing more than a centrifugal fan. , or axial flow fans, because these fans will generate a huge air pressure during the process of filling and deflation, so that the motors driving these fans must use greater force to overcome the strong air pressure and make the fan to turn

[0003] Therefore, some existing inflation and deflation devices often have a phenomenon of heating and burning after a few seconds of use, and the general device must be assembled with a high-priced motor, which increases the cost.
