[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] See attached document Figure 1 - Appendix Figure 4 The present invention provides a display back cover, comprising:

[0026] The monitor back cover body 1 has two ventilation slots 2 on the front side of the monitor back cover body 1, and each ventilation slot 2 is equipped with a filter screen 3.

[0027] The cleaning mechanism is located inside the two ventilation slots 2 and is used to scrape dust off the surface of the filter screen 3.

[0028] The cleaning mechanism includes a crossbar 4, which is located on the front side of the monitor rear shell body 1. Two horizontal plates 5 are fixedly connected to the front side of the monitor rear shell body 1. A limit rod 6 is fixedly connected between the two horizontal plates 5. A lifting lever 7 is sleeved on the outside of the limit rod 6. The lifting lever 7 is fixedly connected to the crossbar 4.

[0029] In this embodiment, by using the user to pull down the lifting lever 7, the two scrapers 11 are moved down to scrape off the dust accumulated on the surface of the filter screen 3 inside the ventilation slot 2, so that the dust enters the collection box 17 for cleaning and collection.

[0030] To achieve the purpose of dust cleaning, this device adopts the following technical solution: The cleaning mechanism also includes two connecting rods 8, which are fixedly connected to both sides of the crossbar 4. The inner sides of the two ventilation slots 2 are provided with connecting slots 9, and the two connecting rods 8 are respectively embedded in the two connecting slots 9. The cleaning mechanism also includes two connecting plates 10, which are respectively embedded in the two ventilation slots 2. The two connecting plates 10 are respectively fixedly connected to the outer ends of the two connecting rods 8. The two ventilation slots 2 are each provided with scrapers 11, and the two scrapers 11 are respectively located on the outer side of the two connecting plates 10. The front side of the display back cover body 1 is provided with two collection boxes 17, which are respectively connected to the two ventilation slots 2. The front side of the two collection boxes 17 is provided with a cover plate 18.

[0031] The user pulls down the lifting lever 7, which moves the horizontal plate 5 and the horizontal bar 4 downward. The horizontal bar 4 moves down, which moves the two connecting rods 8 downward. The two connecting rods 8 move down, which moves the two connecting plates 10 and the scraper 11 downward. The two scrapers 11 move down inside the ventilation slot 2, causing the dust accumulated on the surface of the filter screen 3 to fall down and enter the collection box 17.

[0032] To achieve the goal of fully removing dust, the device employs the following technical solution: two sliders 12 are fixedly connected to the inner sides of each of the two scrapers 11; two grooves are opened on the outer sides of each of the two connecting plates 10; the sliders 12 are embedded in the grooves and slide against the connecting plates 10; multiple sliding rods 13 are fixedly embedded in the grooves and slide against the sliders 12; multiple springs 14 are fixedly embedded in the grooves and are connected to one side of each slider 12; a first magnet 15 is fixedly connected to the outer sides of each of the two scrapers 11; a second magnet 16 is fixedly embedded in the two ventilation slots 2; and the first magnet 15 and the second magnet 16 attract each other.

[0033] When the scraper 11 moves down to its maximum position, the first magnet 15 and the second magnet 16 attract each other, causing the two scrapers 11 to move away from the filter screen 3. This allows the dust trapped between the scraper 11 and the filter screen 3 to fall off completely, preventing dust from being trapped and remaining between the scraper 11 and the filter screen 3.

[0034] The usage process of this utility model is as follows: By pulling down the lifting lever 7, the two scrapers 11 move down to scrape off the dust accumulated on the surface of the filter screen 3 inside the ventilation slot 2, allowing the dust to enter the collection box 17 for cleaning and collection. The user pulls down the lifting lever 7, which moves the horizontal plate 5 and the horizontal bar 4 down. The horizontal bar 4 moves down, which moves the two connecting rods 8 down, which in turn moves the two connecting plates 10 and the scrapers 11 down. The two scrapers 11 move down inside the ventilation slot 2, causing the dust accumulated on the surface of the filter screen 3 to fall off and enter the collection box 17. When the scrapers 11 move down to their maximum position, the first magnet 15 and the second magnet 16 attract each other, causing the two scrapers 11 to move away from the filter screen 3, thus allowing the dust trapped between the scrapers 11 and the filter screen 3 to fall off completely, preventing dust from being trapped and remaining between the scrapers 11 and the filter screen 3.

[0035] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above.
