The positioning plane 121 extends along the axial direction of the annular protrusion 12 to the end of the annular protrusion 12 close to the second component 2. Therefore, the outer peripheral wall profile of the annular protrusion 12 is not circular, similar to a D shape. The axial direction of the annular protrusion 12 is parallel to the axis of the gas nozzle 11. The second component 2 is provided with a groove 22 that cooperates with the annular protrusion 12. The inner peripheral wall profile of the groove 22 matches the outer peripheral wall profile of the annular protrusion 12.

[0043] When the first component 1 and the second component 2 are assembled, the groove 22 is sleeved on the annular protrusion 12 along the axial direction of the annular protrusion 12, which can achieve precise positioning. In the case of precise positioning, the gas nozzle 11 can be smoothly inserted into the air inlet channel 21 without damaging the gas nozzle 11.

[0044] When the first component 1 and the second component 2 are assembled, the groove 22 will first contact the annular protrusion 12. After the position is aligned, the gas nozzle 11 will be inserted into the air inlet channel 21.

[0045] In this embodiment, the air inlet channel 21 includes a sealing ring 211 and an adapter 212 provided on the second component 2. The end of the sealing ring 211 away from the first component 1 is connected to the adapter 212, and the air nozzle 11 is inserted into the sealing ring 211; the sealing ring 211 can seal the outer periphery of the air nozzle 11, and the gas output from the air nozzle 11 is transmitted to the adapter 212 through the sealing ring 211 and transported to a preset position by the adapter 212.

[0046] Preferably, an annular slope 213 is provided on the second component 2, and the annular slope 213 is located at the end of the sealing ring 211 away from the adapter 212. The annular slope 213 is arranged around the through hole of the sealing ring 211, and the diameter of the annular slope 213 gradually increases in the direction away from the sealing ring 211; the annular slope 213 can guide the air nozzle 11 to be inserted into the sealing ring 211.

[0047] In this embodiment, a transition hole 214 is provided between the smaller end of the annular slope 213 and the sealing ring 211, and the air nozzle 11 is inserted into the sealing ring 211 through the transition hole 214;

In other words, the gap between the transition hole 214 and the nozzle 11 is smaller than the interference fit between the nozzle 11 and the sealing ring 211, making it difficult for the nozzle 11 to puncture the sealing ring 211 when inserted.

[0049] In this embodiment, a gap is left between the air nozzle 11 and the adapter 212 ; after assembly, the air nozzle 11 will not hit the adapter 212 , thereby preventing the air nozzle 11 from being damaged.
