[0024] The effect achieved by the entire embodiment 1 is as follows: Figure 2As shown, in actual use, the glass fiber layer 105 is located on the top of the first fixing plate 106 and on both sides, while the foam plastic layer 107 is located at the bottom of the first fixing plate 106 and also on both sides. Then, through the cooperation of the two, when the air flow passes through, its sound waves will be reflected multiple times in the pores, thereby reducing the noise. There are multiple pores that are evenly distributed inside the intake pipe body 101, so that the noise problem can be fully solved.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, dampers 112 are fixedly installed at the front and rear positions of the outer surfaces of both sides of the connecting plate 110, and the protruding ends of the dampers 112 are fixedly connected to the connecting rods 113, and the outer surfaces of the connecting rods 113 are fixedly connected to the buffer pads 108, and the outer surfaces of the buffer pads 108 are slidably connected to the inner surface wall of the intake pipe body 101. The outer surface of the damper 112 is sleeved with a buffer spring 111, and one end of the buffer spring 111 is fixedly connected to the outer surface of the buffer pad 108, and the other end of the buffer spring 111 is fixedly connected to the outer surfaces of both sides of the connecting plate 110. The outer surface of the intake pipe body 101 is fixedly connected to the positions of the two sides near the rear side with the clamping blocks 104, and the outer surface of the clamping blocks 104 A threaded hole 103 is provided near the center of the surface, and the equipment component 2 includes an air filter body 201. A sealing ring 202 is fixedly connected to the center of the front outer surface of the air filter body 201, and a card groove 203 is provided at the center of the inner surfaces on both sides of the sealing ring 202. Bolts 204 are threadedly penetrated at the positions of the card grooves 203 on the outer surfaces of the sealing ring 202 on both sides. The outer surface of the bolt 204 is threadedly penetrated through the outer surface of the block 104. The outer surface of the sealing ring 202 is slidably connected to the outer surface of the intake pipe body 101, the outer surface of the bolt 204 is threadedly connected to the inner surface wall of the threaded hole 103, and the inner surface wall of the card groove 203 is slidably connected to the outer surface of the block 104.

[0026] The effect achieved by the entire embodiment 2 is that, through the mutual cooperation of the damper 112, the buffer spring 111, the connecting plate 110, the second fixed plate 109, the connecting rod 113 and the buffer pad 108, it is possible to absorb the energy of mechanical vibration, thereby reducing the transmission and amplification of vibration, and through the setting of the sealing ring 202, it is possible to increase the sealing of the connection between the intake pipe body 101 and the air filter body 201.

[0027] Working principle: When in use, the user first aligns the block 104 with the slot 203, and then actively puts the air intake pipe body 101 into the sealing ring 202. After being put in, the block 104 will enter the slot 203, and then the user screws the bolt 204 into the corresponding threaded hole 103. Screwing in can limit the position of the air intake pipe body 101, so that it can be stably in the sealing ring 202, and at the same time indirectly ensures that it can be stably in the front side of the air filter body 201. Then in the actual use process, through the setting of the filter 102, it can be achieved to intercept dust or particulate matter in the air to prevent both from entering the equipment together. Figure 2 As shown, air will flow to the position of the first fixed plate 106 and pass through the pores on the glass fiber layer 105 and the foam plastic layer 107. When passing through, the sound waves will be reflected multiple times in the pores, so that the noise can be reduced. Through the mutual cooperation of the damper 112, the buffer spring 111, the connecting rod 113 and the buffer pad 108, the energy of the mechanical vibration can be reduced, thereby reducing the transmission of the vibration.
