The upper end of the mist channel 104 corresponds to and communicates with the mist outlet 103, and the lower end of the mist pipe 102 is necked to form a third step 105 for limiting the sealing pipe 5. The upper end of the sealing pipe 5 is sleeved on the lower end of the mist pipe 102 and corresponds to and communicates with the lower end of the mist channel 104. The sealing pipe 5 also corresponds to the third step 105. The through channel 201 corresponds to the sealing pipe 5 and the fixed pipe 501. The lower end of the sealing pipe 5 is necked to form a fixed pipe 501 and a first step 502. The fixed pipe 501 is inserted into the through channel 201, and the lower end of the through channel 201 is necked to form The second step 202 corresponds to and abuts the first step 502, and the fixed tube 501 is fixed in the through channel 201 through the first step 502 and corresponds to and abuts the second step 202. The fastening tube 4 is wrapped around the outer wall of the sealing tube 5 to fasten the sealing tube 5 to prevent the sealing tube 5 from deformation and displacement. The top end of the fastening tube 4 is closed to form a limiting wall 401 to prevent the sealing tube 5 from being pushed out of the fastening tube 4.
