1. A detection air faucet, comprising a working chamber and a source port in communication with the working chamber, the working chamber provided with a pressure sensing member for sensing a change in a pressure therein, the pressure in the working chamber affected by an object connected to the source port, and the pressure sensing member is provided with a working pressure range, the detection air faucet is characterized in that:
the detection air faucet comprises a working pressure maintaining mechanism implemented by a pressure release structure and a pressure maintaining structure arranged on the detection air faucet, when the pressure in the working chamber exceeds 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 enters into the working chamber by the pressure maintaining structure.
