Further, the rubber ring 231 is provided with a deformation groove 232, the deformation groove 232 is communicated with the channel in the female connector 2, when part of the gas enters the deformation groove 232 of the rubber ring 231, the rubber ring 231 will further deform towards the side close to the connecting pipe 13, so that the sealing between the connecting pipe 13 and the female connector 2 is further improved.

[0031] In order to improve the stability of the connection between the male connector 1 and the female connector 2, the connecting assembly 3 comprises a limiting ring 31, the axis of the limiting ring 31 is coaxial with the axis of the connecting pipe 13, the limiting ring 31 is spaced apart along the axis direction of the connecting pipe 13, and two limiting rings 31 are formed between the two limiting rings 31. Further, the two limiting rings 31 are provided with a relief groove 33, the relief groove 33 is provided with two on the corresponding limiting ring 31, and the relief groove 33 on the two limiting rings 31 is communicated with the limiting groove 32.
