At the same time, when the gas filter 3 is hit or impacted, it will not directly affect the intake pipe 2, and will not cause the intake pipe 2 to twist or deform.

[0028] It is worth mentioning that: the outside of the gas filter 3 is provided with an anti-collision component for protecting it; the anti-collision component includes a pillar 8 arranged around the gas filter 3, the surface of the pillar 8 is provided with a card slot, the outside of the pillar 8 is provided with an elastic protection belt 9 through the card slot sleeve, the elastic protection belt 9 is arranged corresponding to the gas filter 3, the interior of the pillar 8 is a metal rod structure, and the outside is a rubber sleeve, which has the characteristics of being strong inside and tough outside.
