When the moving column 402 moves, the moving column 402 drives the dust suction pipe 104 to adjust and move to the desired position, so as to vacuum cars at different distances, so as to realize the function of the dust suction mechanism to vacuum cars at different distances, so that the dust suction mechanism can adjust the distance between the dust suction pipes 104 according to the distance of the car when in use, so that the dust suction mechanism can better meet the user's usage needs.

[0032] Subsequently, the dust on the surface of the car is sucked into the dust collecting chamber 107 under the action of the dust suction head 108, and the dust is centrally stored in the dust collecting chamber 107. At this time, the input end of the pump body 3031 is away from the inside of the dust guide tube 106. After the dust on the surface of the car is adsorbed, the user operates the control button 101 again, so that the control button 101 controls the first electric push rod 105 to work, and the fixed frame 102 is driven to move under the action of the first electric push rod 105, so that the fixed frame 102 drives the input end of the pump body 3031 to be inserted into the dust guide tube 106. The user operates the control button 101 again, so that the control button 101 controls the pump body 3031 to work, and under the action of the pump body 3031, the dust inside the dust collecting chamber 107 is sucked into the inside of the holding chamber 301 through the dust guide tube 106. Subsequently, The dust enters the dust box 3032 through the through hole body 3033, and the dust is collected in a centralized manner by the dust box 3032. When the user needs to deal with the dust in the dust box 3032, the user pulls the door body to remove the door body from the surface of the fixed frame plate 102, and then pulls the dust box 3032, so that the dust box 3032 drives the guide slider 302 to slide on the inner wall of the fixed frame plate 102, thereby pulling the dust box 3032 out of the fixed frame plate 102, and the dust in the dust box 3032 is processed to realize the dust collection function of the dust collection mechanism, so that the dust collection mechanism can collect the sucked dust and other impurities together when in use, thereby avoiding the phenomenon that the collected dust is difficult to be cleaned during the use of the dust collection mechanism, and making the dust collection mechanism more convenient to use.

[0033] Subsequently, when the dust suction pipe 104 vacuums the dust on the surface of the car, some noise will be generated. The user places the silencer box 201 on the inner wall of the dust suction mechanism body 1 respectively, tightens the mounting studs 202 on the surface of the silencer box 201, and mounts the silencer box 201 on the inner wall of the dust suction mechanism body 1. The user pulls the baffle 205 to remove the baffle 205 from the surface of the silencer box 201, and places the sound-absorbing cotton 203 inside the silencer box 201 so that the sound-absorbing cotton 203 is stuck to the inside of the silencer box 201. Under the action of the sound-absorbing cotton 203, the noise generated by the dust suction pipe 104 when working is absorbed and reduced through the fixing hole 204, so as to realize the sound-absorbing and noise-reducing function of the dust suction mechanism, so that the dust suction mechanism can silence the noise generated during suction when in use, avoiding the phenomenon of huge noise during the use of the dust suction mechanism, and finally completing the use of the dust suction mechanism.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
