The air intake device 6 comprises an air intake pipe 9 fixedly connected to the upper side of the Roots blower body 5, a second driving motor 12 fixedly installed on the front end surface of the air intake pipe 9, a second belt 13 drivingly connected to the output end of the second driving motor 12, a rotating shaft 15 drivingly connected to the second belt 13 away from the second driving motor 12, a cam 14 fixedly sleeved on the output end of the second driving motor 12 and one side of the rotating shaft 15, a filtering device arranged on the inner wall of the air intake pipe 9, and a cleaning device arranged on one side of the inner wall of the air intake pipe 9 for cleaning the surface of the filtering device. The cleaning device includes a second slide bar 23 fixedly connected to one side of the inner wall of the air inlet pipe 9, two sleeves 16 slidably sleeved on the outside of the second slide bar 23, an industrial cleaning brush 17 fixedly connected to the upper side of the sleeve 16, a first slide bar 18 slidably sleeved on the side of the sleeve 16 away from the second slide bar 23, and a plurality of springs 19 sleeved on the outside of the second slide bar 23 and the first slide bar 18. The collecting device 7 includes a collecting box 20 fixedly connected to the upper side of the air inlet pipe 9, a dust suction fan 21 embedded in the right side of the collecting box 20, and an adsorption pad 22 slidably clamped in the middle of the inner wall of the collecting box 20.

[0025] Among them, the driving device includes a first driving motor 2 fixedly installed on the upper right end of the supporting base 1, an output shaft 3 fixedly connected to the output end of the first driving motor 2 and a first belt 4 transmission-connected to the outside of the output shaft 3, the filtering device includes a fixed plate 10 fixedly connected to the inner wall of the air inlet pipe 9, and a dust filter screen cylinder 11 fixedly connected to the right side of the fixed plate 10. The right end of the lower side of the Roots blower body 5 is connected with the exhaust pipe 8, and a plurality of through holes are opened inside the fixed plate 10. The air inlet end of the Roots blower body 5 passes through the right side of the air inlet device 6 and extends to the inside of the dust filter screen cylinder 11. The exhaust end of the Roots blower body 5 is interconnected with the left side of the exhaust pipe 8. The side of the first belt 4 away from the output shaft 3 is transmission-connected to the output end of the Roots blower body 5.

A plurality of springs 19 are divided into two groups in pairs, and the right side of the dust filter screen cylinder 11 is fixedly connected to the right end surface of the inner wall of the air inlet pipe 9.

[0026] It should be noted that the multiple through holes opened on the surface of the fixed plate 10 can effectively allow the inhaled gas to be evenly filtered through the dust filter cylinder 11 into the Roots blower body 5 and discharged from the exhaust pipe 8. The adsorption pad 22 is made of a mixture of sponge and cotton, which can effectively adsorb dust and impurities and avoid contact with the dust suction fan 21 for protection. When not in use, the adsorption pad 22 can be slid out from the upper side of the collection box 20 for replacement and cleaning. The industrial cleaning brush 17 itself has air holes that can cooperate with the left side pipe of the collection box 20 to clean the surface of the dust filter cylinder 11, which reduces the need for manual cleaning and improves the working efficiency of the Roots blower body 5.

[0027] The working principle of the above embodiment is:

[0028] The first drive motor 2 drives the Roots blower body 5 to operate through the first belt 4, and the gas enters the interior from the upper left end of the intake pipe 9, and passes through the dust filter cylinder 11 to absorb dust and impurities in the air and is discharged from the exhaust pipe 8. During the operation of the intake pipe 9, the output end of the second drive motor 12 drives the two cams 14 to rotate and contact the left surface of the sleeve 16 through the second belt 13. The sleeve 16 is pushed to the right with the thrust, and the industrial cleaning brush 17 moves to the right to clean the surface of the dust filter cylinder 11, and the right side of the sleeve 16 contacts the spring 19. The industrial cleaning brush 17 is pressed against the surface of the dust filter 11 to remove dust and impurities from the filter 11. The dust filter 11 is then cleaned by the industrial cleaning brush 17. The cleaning process is repeated several times. During the cleaning process, the dust suction fan 21 is started and connected to the upper side of the industrial cleaning brush 17 to absorb the cleaned dust and impurities and discharge them into the collection box 20. The dust and impurities are then adsorbed and collected on the surface of the adsorption pad 22, thereby reducing the blockage on the surface of the dust filter 11 and achieving the purpose of automatically cleaning the surface of the dust filter 11.
