[0010] In an improved solution, the main air intake pipe is positioned higher than the first and second auxiliary air pipes, the lower side wall of the front part of the main air intake pipe is connected to the transverse pipe section of the second auxiliary air pipe, and the lower side wall of the middle part of the main air intake pipe is connected to the supporting ribs, so that the main air intake pipe can be supported by the connection between the supporting ribs and the second auxiliary air pipes, and the overall structural reliability is better.

[0011] In an improved solution, the distance between the rear end of the main air intake pipe and the inlets of the two three-way valves is equal, which is beneficial to improving the flow stability of the gas from the main air intake pipe to the first main branch pipe and the second main branch pipe.
