[0058] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0059] like Figures 1 to 11 As shown, a vacuum cleaning workbench includes a workbench body 10 and an electrical control box 17. A roller 11 is installed at each of the four corners of the lower end face of the workbench body 10. The four rollers 11 allow the workbench body 10 to be moved, facilitating position adjustment and improving usability. A grid surface 12 is installed on the workbench body 10.
[0060] A filter cartridge 14 is installed in the workbench body 10 below the grid table 12 via a filter cartridge bracket 41613. A dust collection trough 15 is installed in the workbench body 10 below the filter cartridge 14, and a dust collection drawer 16 is slidably installed in the dust collection trough 15.
[0061] A dust extraction fan 32 is installed inside the workbench body 10 on one side of the filter cartridge 14. A backflushing installation chamber 21 and a dust extraction fan installation chamber 31 are provided inside the workbench body 10 below the grille surface 12.
[0062] The backwash installation chamber 21 and the dust extraction fan installation chamber 31 are arranged side by side in the workbench body 10, with the backwash installation chamber 21 located between the filter cartridge 14 and the dust extraction fan installation chamber 31.
[0063] The backflushing mounting chamber 21 has a first through hole 211 communicating with the interior of the filter cartridge 14 and a second through hole 212 communicating with the vacuum cleaner mounting chamber 31. A backflushing mechanism 22 is installed in the backflushing mounting chamber 21 for extending into the filter cartridge 14 through the first through hole 211 to backflush it. The electrical control box 17 is electrically connected to the vacuum cleaner 32 and the backflushing mechanism 22.
[0064] In this embodiment, the backflushing mechanism 22 includes an air tank 221 and a pulse valve 222 disposed on the air tank 221. The injection port 223 of the pulse valve 222 extends into the filter cartridge 14 through the first through hole 211. The electrical control box 17 is electrically connected to the pulse valve 222.
[0065] The vacuum cleaner fan 32 is installed in the vacuum cleaner fan installation chamber 31, which has an air outlet. The air outlet is formed on the right end face of the workbench body 10. In this embodiment, the vacuum cleaner fan 32 is a diagonal flow vacuum cleaner fan, and the air inlet 323 of the diagonal flow vacuum cleaner fan is provided and connected to the second through hole 212. The diagonal flow vacuum cleaner fan includes a diagonal flow impeller 321 and a motor 322 for driving the diagonal flow impeller 321 to rotate. The motor 322 is electrically connected to the electrical control box 17. The air inlet 323 of the diagonal flow vacuum cleaner fan is formed on the diagonal flow impeller 321, and the diagonal flow vacuum cleaner fan has a fan outlet 324, with an obtuse angle between the fan outlet 324 and the air inlet 323. When the motor 322 drives the diagonal flow impeller 321 to rotate, the axial air coming in from the second through hole 212 enters the diagonal flow impeller 321 through the air inlet 323 and enters the dust collection fan installation chamber 31 at an angle from the fan outlet 324.
[0066] It also includes a sound-absorbing device 40 for absorbing sound from the vacuum cleaner fan 32, which is installed on the right side of the workbench body 10. The sound-absorbing device 40 has an air inlet 401 and an air outlet 402, the air inlet 401 being connected to the air outlet, and an exhaust pipe 50 being provided on the sound-absorbing device 40, which is connected to the air outlet 402.
[0067] The sound-absorbing device 40 is located on the right side of the workbench body 10. The sound-absorbing device 40 includes a housing 41 and a plurality of sound-absorbing panels 41 arranged at intervals within the housing 41. In this embodiment, the sound-absorbing panels 41 are arranged side by side with equal intervals from front to back.
[0068] The air inlet 401 is formed on the left end face of the housing 41, and the air outlet 402 is formed on the upper end face of the housing 41.
[0069] In this embodiment, the sound-absorbing panel 41 has a cross-section that is narrower on the right and wider on the left, resembling a right-angled trapezoid. The sound-absorbing panel 41 includes a first galvanized perforated plate 411, a second galvanized perforated plate 412, and a first double-layer fiberglass cloth 413, glass wool 414, and a second double-layer fiberglass cloth 415 located between the first galvanized perforated plate 411 and the second galvanized perforated plate 412. Preferably, the sound-absorbing panel 41 further includes a support 416 with front and rear openings. The first galvanized perforated plate 411 and the second galvanized perforated plate 412 are respectively installed at the front and rear openings of the support 416, and the first double-layer fiberglass cloth 413, glass wool 414, and second double-layer fiberglass cloth 415 are located within the support 416.
[0070] The working principle will be explained in general terms below:
[0071] When the vacuum cleaner fan 32 is working, the dust-laden gas enters the workbench body 10 through the grille surface 12. Larger and heavier dust particles settle into the dust collection drawer 16 in the dust collection trough 15 due to gravity. When the gas containing finer dust passes through the filter cartridge 14, the dust is trapped and the gas is purified. The purified gas enters the backwash installation chamber 21, and then enters the vacuum cleaner fan installation chamber 31 under the action of the inclined flow vacuum cleaner fan. Finally, it is discharged through the sound absorption device 40 and the exhaust pipe 50.
[0072] The key design feature of this utility model is that it mainly uses a backflushing mechanism to backflush the filter cartridge, which helps to enhance the purification capacity of the filter cartridge. Moreover, with the cooperation of a sound-absorbing device, it can achieve quiet operation during the dust collection process, greatly improving the user's processing comfort.
[0073] Secondly, the use of casters enables the worktable to be movable, greatly improving ease of use.
[0074] Furthermore, the dust collection drawer allows for timely cleaning of accumulated dust.
[0075] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
