[0020] Furthermore, there are two groups of intake pipes 2 symmetrically distributed, and each group of intake pipes 2 has two symmetrically distributed, which facilitates the intake and combustion of different channels.

[0021] Furthermore, a through hole is formed on the outer wall of the support plate 3 , and the support plate 3 is connected to the air intake pipe 2 via a valve, so that the air intake port of the air intake pipe 2 can be controlled conveniently via the valve.

[0022] Furthermore, the support rods 4 are welded to the support plate 3 and the support frame 5 respectively, and the support rods 4 are distributed at equal angles along the axial center line of the support plate 3, which facilitates the support plate 3, the support rods 4 and the support frame 5 to support the drive motor 6.
