The invention discloses a maintenance-free automobile refrigerant quantity observer which comprises a pressure gauge, a cap body and a pressing body, the pressure gauge is arranged at the top of the cap body, the pressing body is arranged in the cap body, and an air channel is formed in the end face of the bottom end of the pressing body. The top end of the air channel penetrates through the cap body and extends to the top surface of the cap body to be communicated with the pressure gauge, when the cap body is screwed at the filling port, the pressing body extrudes the valve core to open the valve core, the cap body comprises a cover body and a cylinder body, the cylinder body is arranged on the bottom surface of the cover body, and the driving assembly is arranged on the cylinder body. The containing cavity is formed in the cover body, the air channel is divided into the two sections, the two sections of air channels are communicated through the channel in the cover body, the sealing assembly is arranged to be used for opening or closing the air channel, and therefore refrigerant leakage caused by long-term opening of the air channel can be prevented. The maintenance-free automobile refrigerant quantity observer has the effects of controlling opening or closing of the air channel and preventing refrigerant leakage.
