As shown in fig. 2, the filter 21 comprises a switching assembly 22 and several filter segments. The plurality of filter segments can be filter segments which are arranged in response to special conditions, or can be filter segments which are used at ordinary times, and at least one filter segment which is arranged in response to special conditions.

Specifically, the dust filtering section 23 performs a dust-proof action when the vehicle 2 is in a dust weather or road condition, including: the first ash leakage valve 232 is opened to open the sand outlet so that sand can be discharged from the sand outlet. For example, when the air filter intake pipe assembly 20 is controlled to perform the sand prevention mode in order to prevent sand from entering the air intake system 1 when the air filter intake pipe assembly is currently located at a construction site, the switching component 22 drives the sand filter segment 23 to be communicated with (or conducted with) the intake pipe 90, and then the first ash leakage valve 232 is controlled to be opened so that the sand outlet is opened, and a large amount of sand is blocked by the first filter screen 231 and discharged from the sand outlet.

Thus, the sand filtering section 23 can filter out sand in advance, prevent sand from entering the air intake system 1, thereby causing the function of the air intake system 1 to be attenuated or even damaged, and finally causing the engine 3 to be damaged to different extents, so that the requirements of users on the vehicle 2 in sand road conditions and weather can be met.

Specifically, when the vehicle 2 is in rainy weather or road conditions, the rain filter segment 24 performs a rain-proof action including: the first cyclone sheet 241 is controlled to be started, and the drain valve 242 is controlled to be opened, so that rainwater in the second filter pipe 240 is firstly rotationally separated to the pipe wall of the second filter pipe 240 through the first cyclone sheet 241, and then is discharged through a rainwater outlet. For example, when the air filter intake pipe assembly 20 is controlled to perform a waterproof mode in order to prevent rainwater from entering and affecting the normal operation of the air intake system 1 in overcast and rainy weather, the switching component 22 drives the rainwater filter section 24 to be communicated with the air intake pipe 90, then controls the first cyclone sheet 241 to be started, and controls the drain valve 242 to be opened, and after rainwater enters the second filter pipe 240, the rainwater is separated onto the pipe wall of the second filter pipe 240 through the first cyclone sheet 241, and then the rainwater is discharged from the rainwater outlet.

Thus, the rainwater filtering section 24 can filter rainwater in advance, prevent rainwater from entering the air inlet system 1, so that functions of the air inlet system 1 are attenuated or even damaged, and finally, the engine 3 is damaged to different degrees, and thus, the requirements of users on the vehicle 2 in the case of rainwater road conditions and weather can be met.
