[0029] Furthermore, the threaded sleeve 501 is threadedly connected to the outer wall of the long rod 58, a through hole is opened at the bottom of the air outlet pipe 56, and the through holes are distributed in a circular array, and a circular hole is opened at the bottom of the air inlet plate 4 corresponding to the air outlet pipe 56 to facilitate better exhaust.

[0030] Furthermore, an opening matching the transfer square tube 52 is provided on the back of the air intake plate 4. The transfer square tube 52 is fixedly connected to the inner wall of the opening. The transfer square tube 52 is connected to the inner wall of the air intake channel 51 through the air intake pipe 53, so as to facilitate better gas transportation.

[0031] Furthermore, a connecting hole is opened on the front side of the air inlet channel 51, and the air inlet channel 51 is connected with the long tube 54 through the connecting hole, and the long tube 54, the short tube 55 and the air outlet pipe 56 are connected with each other.
