Specifically, in the present embodiment, 8 air holes are provided on the rotating disk, and Arabic numerals "1, 2, 3, 4, 5, 6, 7, 8" are marked in the counterclockwise direction. Since the 8 air holes are evenly arranged, the number "1" and the number "5" are located on the same diameter, the number "2" and the number "6" are located on the same diameter, the number "3" and the number "7" are located on the same diameter, and the number "4" and the number "8" are located on the same diameter; at the same time, the outer wall of the shell is correspondingly provided with an alignment mark; when the number "1" rotates to the outside of the shell and is aligned with the alignment mark on the outer wall of the shell, the air hole corresponding to the number "5" is located on the gas channel inside the shell; similarly, the number "2" is aligned with the alignment mark on the shell When timing, the air hole corresponding to the number "6" is located on the gas channel inside the shell; when the number "3" is aligned with the alignment mark on the shell, the air hole corresponding to the number "7" is located on the gas channel inside the shell; when the number "4" is aligned with the alignment mark on the shell, the air hole corresponding to the number "8" is located on the gas channel inside the shell; when the number "5" is aligned with the alignment mark on the shell, the air hole corresponding to the number "1" is located on the gas channel inside the shell; when the number "6" is aligned with the alignment mark on the shell, the air hole corresponding to the number "2" is located on the gas channel inside the shell; when the number "7" is aligned with the alignment mark on the shell, the air hole corresponding to the number "3" is located on the gas channel inside the shell; when the number "8" is aligned with the alignment mark on the shell, the air hole corresponding to the number "4" is located on the gas channel inside the shell.
