Please refer to Figures 1-3. In order to maintain the dust removal and ventilation effect of the equipment, the cleaning mechanism 3 in this embodiment includes a protective plate 308 fixed to the upper surface of the filter box 1, a driving component arranged on the filter box 1 and the protective plate 308, and a cleaning component arranged on the driving component.

Among them, the driving component includes two threaded rods 301 rotatably connected between the upper and lower sides of the inner wall of the filter box 1, a forward and reverse motor 302 fixed to the left side of the upper surface of the protective plate 308, a first transmission wheel 303 fixed to the top of the outer surface of the left end threaded rod 301, a second transmission wheel 304 fixed to the top of the outer surface of the right end threaded rod 301, and a conveyor belt 305 connected between the first transmission wheel 303 and the second transmission wheel 304, which is convenient for driving the two adjustment sliders 306 to move so as to drive the cleaning brush 307 to move, so as to facilitate the subsequent cleaning of the filter net 4, thereby improving the dust removal effect.

At the same time, the cleaning component includes an adjusting slider 306 threadedly connected to the outer surface of the threaded rod 301 and a cleaning brush 307 fixed to the right side of the adjusting slider 306. The right side of the cleaning brush 307 slides and fits with the left side of the filter 4. The two cleaning brushes 307 can move to clean the dust on the two filters 4 respectively, avoiding the long-term accumulation of dust on the surface of the filter 4 and affecting the dust removal effect.

In addition, the output shaft of the forward and reverse motor 302 is fixed to the top of the left-end threaded rod 301, and the top of the right-end threaded rod 301 is rotatably connected to the right side of the inner top wall of the protective plate 308, which can make the two threaded rods 301 more stable when rotating, and thus can more stably drive the adjustment slider 306 located on its outer surface to move, which is convenient for subsequent dust removal.

In addition, the cross-section of the protective plate 308 is U-shaped, and the first transmission wheel 303, the second transmission wheel 304 and the conveyor belt 305 are all located inside the protective plate 308, providing protection for the first transmission wheel 303 and the second transmission wheel 304, so that they can work more stably.

The working principle of the above embodiment is:

When the fan 5 is started, the air and the impurities and dust contained in the air are sucked into the filter box 1 through the ventilation duct 2 under the high pressure generated by the high-speed rotation inside the fan 5, and then the impurities and dust contained in the air are intercepted and filtered for multiple times through the two filter screens 4 in turn, so as to improve the dust filtering effect in the air, and then the air after double filtration and interception is transmitted to the water tank 8 through the air inlet pipe 6 and the air outlet pipe 7, so that the dust in the air at this time is further adsorbed and filtered, so as to further improve the dust removal effect, and then the purified and dust-removed air can be discharged through the air outlet pipe 9, so as to effectively avoid the problem that dust enters the workshop and affects the production of electronic components, and indirectly improve the production quality. At the same time, the forward and reverse motors 302 can be started to drive the left end threaded rod 301 and the first transmission wheel 303 to rotate, and then the first transmission wheel 303 is driven by the conveyor belt 305. The second transmission wheel 304 is driven to rotate, which can drive the right end threaded rod 301 to rotate. At this time, the first transmission wheel 303, the second transmission wheel 304 and the conveyor belt 305 are all located inside the protective plate 308, so that the first transmission wheel 303 and the second transmission wheel 304 can be protected to a certain extent, and can more stably drive the right end threaded rod 301 to rotate. At the same time, since the inner right side wall of the top protective plate 308 of the right end threaded rod 301 is rotatably connected, the rotation of the right end threaded rod 301 is more stable, and then the two adjusting sliders 306 and the two cleaning brushes 307 can be driven to move more stably. Since the right side of the cleaning brush 307 is slidably fitted with the left side of the filter screen 4, the cleaning brush 307 can clean the filter screen 4 in a timely and stable manner, reduce the possibility of dust adsorbed on the filter screen 4, and prevent dust from accumulating on the surface of the filter screen 4 for a long time, affecting the dust removal effect.
