[0022] One end of the top spring 39 away from the plug 38 is fixedly connected to a fixed cover 32 through a fixing frame, the position of the top spring 39 is restricted by the fixing frame, the top of the fixed cover 32 is fixedly connected to the inner wall of the mixing shell 1, the inner wall of the fixed cover 32 is slidably connected to the outer wall of the plug 38, and the bottom of the fixed seat 34 is fixedly connected to the top of the mixing shell 1.

[0023] The adjusting assembly 4 includes a baffle 41. The inner wall of the baffle 41 is rotatably connected to a fixed cylinder 42 through a rotating shaft. The outer wall of the baffle 41 is fixedly connected to an adjusting handle 44. The outer wall of the adjusting handle 44 is slidably connected to a limiting plate 45. The outer wall of the baffle 41 is slidably connected to the inner wall of the shunt pipe 2. The inner wall of the adjusting handle 44 is slidably connected to a plug 46. The outer wall of the plug 46 is slidably connected to the inner wall of the limiting plate 45. The inner wall of the shunt pipe 2 is fixedly connected to a stop block 43.

The outer wall of the fixed cylinder 42 is fixedly connected to the inner wall of the shunt pipe 2. The outer wall of the shunt pipe 2 is fixedly connected to the outer wall of the limiting plate 45.

[0024] Working principle:

[0025] During use, first, the opening degree of the shunt pipe 2 is adjusted through the adjusting assembly 4, thereby adjusting the amount of waste gas passing through the shunt pipe 2. Subsequently, the waste gas flow of the four adjusting assemblies 4 of the shunt pipe 2 can be adjusted through the opening and closing assembly 3 at the top of the mixing housing 1.

[0026] When using the adjusting assembly 4, first, the plug 46 on the adjusting handle 44 is slid out of the limiting plate 45 to release the locking of the adjusting handle 44. Then, the position of the adjusting handle 44 can be adjusted to make the baffle 41 rotate along the fixed cylinder 42, thereby changing the opening angle of the baffle 41 in the shunt pipe 2. After the position of the baffle 41 is adjusted, the plug 46 is slid back into the groove in the limiting plate 45 to re-lock the position of the adjusting handle 44. It should be noted that when the baffle 41 touches the stop block 43, it means that the baffle 41 is closed in place.

[0027] When using the opening and closing assembly 3, first, the stop rod 37 is slid out of the positioning block 36 to release the restriction on the lever 35. Then, the position of the lever 35 can be adjusted. Just rotating the lever 35 can synchronously drive the pressing block 33 to rotate along the fixed seat 34, so as to press the pressing column 31 through the pressing block 33. There are two pressing columns 31 below the pressing block 33. When the pressing block 33 presses one pressing column 31, the oppression on the other pressing column 31 is released.

[0028] When the pressing column 31 is released, it will push the plug 38 upward under the push of the top spring 39, so that the plug 38 fits on the fixed cover 32 to block the waste gas from passing through the fixed cover 32. When the pressing column 31 is oppressed, it will push the plug 38 downward to slide out of the fixed cover 32, and the waste gas can enter the mixing housing 1 through the fixed cover 32.

[0029] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art and related fields based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.
