Beschreibung
Zusammenfassung:	The detection mechanism comprises a main body piece, an air source and a pressure sensor, a detection cavity is formed in the main body piece, an air inlet and an air outlet are formed in the main body piece, the detection cavity is used for communicating the air inlet, the air outlet and a communicating opening of the electrode holder, and the pressure sensor is arranged on the main body piece. The main body part is provided with an air inlet and an air outlet, the communication port is used for covering the electrode cap, the air source is arranged on the main body part, the air source is communicated with the air inlet and is used for conveying air to the detection cavity, and the pressure sensor is arranged on the main body part and is used for detecting the air pressure value at the air outlet. According to the technical scheme provided by the utility model, by testing the air pressure value of the air outlet, when the electrode cap falls off, the gas in the detection cavity leaks from the communication
