Detection air faucet

Abstract

The invention provides a detection air faucet, including a working chamber and a source port in communication with the working chamber. The working chamber is provided with a pressure sensing member for sensing a change in the pressure in the chamber, and the pressure in the working chamber is affected by an object connected to the source port. The pressure sensing member is provided with a working pressure range. Furthermore, the detection air faucet includes a working pressure maintaining mechanism implemented by a pressure release structure and a pressure maintaining structure. When the pressure in the working chamber exceeding the working pressure range, the working chamber discharges air by the pressure release structure, and when the pressure in the working chamber is lower than a pressure outside the detection air faucet, the air outside the detection air faucet entering into the working chamber by the pressure maintaining structure.
