During the dust removal process, the operator can observe the instrument through the observation window 2 made of transparent glass in the side groove. The sliding observation window 2 allows for observation of the dust removal process inside the device from different angles, ensuring normal operation. Dust is blown into the dust collection hopper 15 by the airflow generated by the blower, and then enters the dust collection bags 17 arranged in an array below through the dust outlet 16 at the bottom of the hopper 15. The dust collection bags 17 effectively collect dust and prevent leakage. The control valve 18 controls the amount of dust entering the dust collection bags 17 according to actual conditions. After dust removal is completed, press switch 8 to turn off the equipment. When the dust collection bags 17 have collected a certain amount of dust, they can be cleaned or replaced by opening the inspection window 19 on the rear side of the bottom box 10. The dust collection hopper 15 should also be inspected regularly and cleaned if necessary. The entire process involves the coordinated operation of components corresponding to their respective part numbers, achieving efficient dust removal, stable fixation, and effective dust collection and treatment for the LCD instrument.

[0035] like Figure 1-2 and Figure 4 As shown, a placement net 14 is provided in the middle of the main body 1 of the dust removal device, a bottom box 10 is provided at the bottom of the main body 1 of the dust removal device, and a positioning net 11 is provided above the placement net 14. The placement net 14 is made of woven metal wire, and the positioning net 11 is made of woven nylon rope. Insertion plates 12 are provided on the left and right sides of the positioning net 11, and sliding grooves 13 are provided on the left and right sides of the placement net 14. The insertion plates 12 and sliding grooves 13 are slidably connected. A dust collection hopper 15 is provided at the top of the bottom box 10, and a dust outlet 16 is provided at the bottom of the dust collection hopper 15. Four dust collection bags 17 are arranged in an array at the bottom of the dust outlet 16. A control valve 18 is provided at the top of the dust collection bags 17. An inspection window 19 is provided at the rear of the bottom box 10.

[0036] Preferably, the wire mesh 14 has high strength, which can stably support the LCD instrument and ensure its stability during dust removal. It will not shake due to airflow disturbances inside the device, providing a good foundation for dust removal work. The nylon rope woven positioning mesh 11 is soft and can prevent scratching the instrument surface when fixing it, thus providing protection. Simultaneously, the positioning mesh 11 is slidably connected to the groove 13 on the placement mesh 14 via the plug-in plate 12. This structure facilitates the installation and removal of the positioning mesh 11 and allows for flexible adjustment according to different sizes of LCD instruments, enhancing the versatility of the device. The dust collection hopper 15 located above the bottom box 10 has a special shape. The design effectively collects dust blown down from above, concentrating it at the dust outlet 16 to improve dust collection efficiency. Four dust collection bags 17 are arrayed at the bottom of the dust outlet 16, with control valves 18 at the top of each bag. These valves allow for flexible control of the amount of dust entering each bag based on dust collection conditions. The simultaneous operation of multiple dust collection bags 17 increases dust collection capacity and facilitates subsequent cleaning and replacement. An inspection window 19 at the rear of the bottom box 10 allows for regular inspection, cleaning, and maintenance of the interior, ensuring timely removal of dust from the dust collection hopper 15 and dust collection bags 17, guaranteeing normal operation of the device and extending its service life.

[0037] like Figure 3-4 As shown, an observation window 2 is provided at the upper front side of the main body 1 of the dust removal device, and side grooves 3 corresponding to the observation window 2 are provided on the left and right sides of the main body 1 of the dust removal device. The observation window 2 is slidably connected to the main body 1 of the dust removal device through the side grooves 3. The observation window 2 is made of transparent glass.

[0038] Preferably, the observation window 2, made of transparent glass, has good visibility.

The operator can slide the observation window 2 along the side groove 3 according to actual needs to observe the inside of the device from different angles and fully understand the dust removal process. Compared with a fixed observation window, the sliding observation window 2 greatly increases the flexibility and comprehensiveness of observation, better meets the observation needs in actual operation, and further improves the practicality and convenience of the dust removal device.

[0039] like Figure 1-4 As shown, slots 6 are arranged in an array inside the top cover 4, and filters 5 are nested inside the slots 6.

[0040] Optionally, the recessed slots 6 arranged in an array inside the top cover 4 provide a stable and precise installation position for the filter screen 5. This array design allows multiple filter screens 5 to be evenly distributed inside the top cover 4, thereby more comprehensively filtering the air entering the device. At the same time, the structure of the recessed slots 6 can tightly hold the filter screen 5, ensuring that the filter screen 5 will not easily shift or fall off during device operation, even if it is subjected to airflow impact or external vibration, thus ensuring the stability and reliability of the filtration system. The filter screen 5 is nested inside the recessed slots 6. This connection method is not only easy to install, but also facilitates the disassembly and replacement of the filter screen 5 later. When the filter screen 5 has been used for a period of time and has absorbed a lot of dust, resulting in a decrease in filtration effect, it can simply be easily removed from the recessed slot 6 and replaced with a new filter screen 5. No complicated tools or operations are required, reducing maintenance costs and improving the maintainability of the equipment. In addition, the nested connection can also ensure the sealing between the filter screen 5 and the top cover 4, preventing unfiltered air from entering the device from the edge gaps, effectively improving the air filtration effect, and thus ensuring the dust removal environment quality of the LCD instrument.
