Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6A shopping mall exhaust system based on PLC control includes a housing 1, a control component 11, and an exhaust component 12. The exhaust component 12 includes a motor and an exhaust fan. The control component 11 is connected to the shopping mall's PLC control system, which can control the start and stop of the control component 11. Simultaneously, the control component 11 can drive the start and stop of the motor. The control component 11 and the exhaust component 12 are installed inside the housing 1. A filter plate 29 is installed inside the housing 1 to filter dust, preventing large amounts of dust and impurities from entering the exhaust system and affecting subsequent exhaust operations. The housing 1 has two rotatable threaded rods 2, which rotate to move threaded sliders 21. Threaded sliders 21 are threaded onto the outer sides of the two threaded rods 2. A collection box 22 is fixed to the top of the two threaded sliders 21. The bottom of the inner wall of the collection box 22 has a slope. When the baffle 32 is opened, dust can fall into a cleaning box 3. The collection box 22 can collect and process the dust. The collection box 22 is located... Below the filter plate 29, a rotating rod 23 is provided inside the collection box 22. A cleaning brush 24 is installed on the outside of the rotating rod 23, and the cleaning brush 24 is attached to the bottom end of the filter plate 29. A gear 25 is installed on the outside of the rotating rod 23. A toothed plate 26 is fixedly provided on the inner wall of the box 1. By translating the rotating rod 23, the gear 25 can move on the outside of the toothed plate 26, thereby rotating. The gear 25 and the toothed plate 26 mesh with each other. An opening is provided on the side of the box 1. A square trough 15 is provided. A cleaning box 3 is installed on the side of the box body 1 near the square trough 15. An inclined plate 31 is installed inside the cleaning box 3. A baffle 32 is rotatably provided on the side of the collection box 22 near the square trough 15. A connecting rod 33 is fixedly provided on the outside of the baffle 32. The connecting rod 33 and the inclined plate 31 are on the same horizontal line. When the connecting rod 33 contacts the inclined plate 31, the baffle 32 will flip open as the collection box 22 and the connecting rod 33 move, and the dust will fall into the cleaning box 3 along the slope.

[0027] Slots 4 are provided around the inner wall of the housing 1. The filter plate 29 is movably inserted into the slots 4, and the slots 4 can limit the position of the filter plate 29. An installation plate 41 is fixedly attached to the outer side of the filter plate 29. A sealing gasket 42 is fixedly attached to the side of the installation plate 41 near the housing 1. The sealing gasket 42 can ensure the sealing of the housing 1. Bolts 43 distributed in a rectangular array are threaded into the installation plate 41. The bolts 43 are inserted through the outer side of the housing 1. The bolts 43 can be used to easily install and remove the filter plate 29, thereby facilitating its maintenance and replacement.

[0028] A louvered fan 14 is installed on the inner wall of the bottom end of the housing 1. The louvered fan 14 can prevent large impurities from entering the device and can also change the airflow direction. An installation plate 13 is installed and fixed on the top of the housing 1. The installation plate 13 can be easily connected to the external exhaust duct.

[0029] The top of the collection box 22 is fixed with symmetrically distributed side plates 27, which can guide dust into the collection box 22.

[0030] A cleaning plate 35 is detachably installed on the side of the cleaning box 3 away from the box body 1, and the cleaning plate 35 can clean dust.

[0031] A motor 28 is installed on the outside of the housing 1. The end of the output shaft of the motor 28 is inserted through the housing 1 and fixedly connected to one of the threaded rods 2, so that the rotation of the end of the output shaft of the motor 28 causes the rotation of one of the threaded rods 2 to provide power output.

[0032] The two threaded rods 2 have the same thread direction and are connected to the synchronous belt via a synchronous pulley, so that the two threaded rods 2 rotate synchronously via the synchronous pulley and the synchronous belt.

[0033] The baffle 32 is equipped with symmetrically distributed counterweights 34 on its outer side. Under the action of the counterweights 34, the baffle 32 will always be closed and installed on the outside of the collection box 22 when the baffle 32 is not subjected to external force.

[0034] In use, first connect the device to the mall's ventilation system via the installation panel 13. Simultaneously, connect the control component 11 to the mall's PLC system. The PLC system controls the start and stop of component 11, which in turn controls the start and stop of the ventilation component 12, facilitating easy opening and closing. During ventilation, the ventilation component 12 exhausts air from the mall, filtering dust through the filter plate 29. When cleaning the dust on the outside of the filter plate 29 is required, start the motor 28. The output shaft of the motor 28 rotates, driving one of the threaded rods 2 to rotate. This rotation, via a synchronous pulley and belt, causes both threaded rods 2 to rotate synchronously. The rotation of the threaded rods 2 moves the threaded slider 21. The movement of the slider 21 drives the collection box 22 to move, which in turn drives the rotating rod 23 and the cleaning brush 24 to move. Simultaneously, the rotating rod 23 drives the gear 25 to move, which in turn rotates under the action of the toothed plate 26. This rotation of the gear 25, in turn, drives the rotating rod 23 and the cleaning brush 24 to rotate. The cleaning brush 24 cleans the dust on the outside of the filter plate 29 and collects it into the collection box 22. Finally, when the collection box 22 moves to the square groove 15, the connecting rod 33 contacts the inclined plate 31. As the collection box 22 moves, the connecting rod 33 drives the baffle 32 to rotate, allowing the dust in the collection box 22 to enter the cleaning box 3, thus facilitating dust cleaning and centralized treatment.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
