[0027] In this embodiment, the width of the second limiting ring 8 is the same as that of the first screw opening 4 , and the width of the feed pipe 9 is the same as the distance between the clamping blocks 13 .

[0028] Specifically, the width of the first limiting ring 5 is the same as that of the first screw hole 4, thereby increasing the sealing performance at the connection between the two. The width of the feed pipe 9 is the same as the distance between the block 13, thereby further increasing the sealing performance between the pipe body and the tower body.

[0029] In this embodiment, a discharge pipe 15 is provided at the lower left end of the tower body, and a first screw hole 4, a second limiting ring 8, and a nut 11 are provided at the connection between the discharge pipe 15 and the tower body 2, and the structure of the nut 11 is consistent with the nut 11 at the feed pipe 9.
