DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Refer to Figure 1 、 Figure 2 and Figure 3, an embodiment provided by the present utility model: a reverse-smoking electric lamp fan with a filtering function, including a connecting block 1. A lighting lamp 2 is fixedly connected to the bottom of the connecting block 1, which facilitates lighting. A dust-proof shell 3 is fixedly connected to the bottom of the lighting lamp 2, and the dust-proof shell 3 can conveniently protect the lighting lamp 2, thereby preventing the lighting lamp 2 from being polluted. A double-headed motor 17 is fixedly connected to the inside of the connecting block 1. The output end of the double-headed motor 17 is fixedly connected to a fan 4. When the double-headed motor 17 operates, it will drive the fan 4 to rotate, thereby driving the air flow direction from bottom to top. A fixing ring 7 is fixedly connected to the outer periphery of the lighting lamp 2. A sleeve 9 is fixedly connected to the outside of the fixing ring 7. A filter plate 8 is arranged in the middle of the fixing ring 7. The fixing ring 7 can conveniently fix the filter plate 8, and the filter plate 8 can filter the smoke and odor flowing from bottom to top.

[0030] Refer to Figure 3 , a movable plate one 11 is slidably connected to the inside of the sleeve 9. A movable plate two 12 is rotatably connected to the bottom of the movable plate one 11. When the movable plate one 11 moves, it will drive the movable plate two 12 to move simultaneously. One end of the movable plate two 12 away from the movable plate one 11 is rotatably connected to a clamping block 13. When the movable plate two 12 moves, it will drive the clamping block 13 to move. One side of the clamping block 13 is fixedly connected to a telescopic rod one 14, and the other end of the telescopic rod one 14 is fixedly connected to the inside of the sleeve 9. A spring one 15 is fixedly connected to the inside of the sleeve 9, and the other end of the spring one 15 is fixedly connected to one side of the clamping block 13. When the clamping block 13 moves, it will squeeze the spring one 15 and the telescopic rod one 14. At the same time, under the action of the spring one 15 and the telescopic rod one 14, the clamping block 13 can be conveniently ejected from the inside of the sleeve 9. A clamping groove 16 is opened on the outside of the filter plate 8, and the clamping groove 16 is engaged with the clamping block 13. A connecting component is arranged on the top of the movable plate one 11.

[0031] Refer to Figure 3 and Figure 4 , the connecting component includes a button 10. The button 10 is fixedly connected to the top of the movable plate one 11. The button 10 is slidably connected to the middle of the sleeve 9. The button 10 facilitates the operator to drive the movable plate one 11 to move. The output end of the double-headed motor 17 away from the fan 4 is fixedly connected to a connecting plate 5. When the double-headed motor 17 operates, it can conveniently drive the connecting plate 5 to rotate. A spring two 19 is fixedly connected to the top of the connecting plate 5, and the other end of the spring two 19 away from the connecting plate 5 is fixedly connected to a scraper 6. When the connecting plate 5 rotates, it will drive the scraper 6 to move simultaneously through the spring two 19. When the scraper 6 moves, it can scrape the surface of the dust-proof shell 3, thereby preventing the lighting lamp 2 from being affected while filtering the smoke and odor. A limiting component is arranged at the bottom of the scraper 6.

[0032] Refer to Figure 3 and Figure 4, the limiting component includes a second telescopic rod 18. The second telescopic rod 18 is fixedly connected to the bottom of the scraper 6. The bottom of the second telescopic rod 18 is fixedly connected to the top of the connecting plate 5. A second spring 19 is sleeved on the outer periphery of the second telescopic rod 18. The second telescopic rod 18 can limit the scraper 6, thereby preventing the scraper 6 from shifting when moving. There are two first telescopic rods 14 and two first springs 15. The two first springs 15 are respectively sleeved on the outer peripheries of the two first telescopic rods 14.

[0033] Referring to Figure 1 and Figure 3 , there are specifically two scrapers 6. The two scrapers 6 are both located at the bottom of the dust-proof shell 3. The two scrapers 6 can more conveniently clean the surface of the dust-proof shell 3. The clamping block 13 is slidably connected to the middle of the sleeve 9.

[0034] Working principle: When it is necessary to disassemble, clean or replace the filter plate 8, pressing the button 10 drives the first movable plate 11 to move. When the first movable plate 11 moves, it drives the second movable plate 12 to move simultaneously. When the second movable plate 12 moves, it drives the clamping block 13 to move, so that the clamping block 13 disengages from the clamping groove 16. After the clamping block 13 disengages from the clamping groove 16, the filter plate 8 can be conveniently removed, and then the filter plate 8 can be conveniently cleaned or replaced, while improving the filtering and purification effect.

[0035] When scraping the surface of the dust-proof shell 3, the double-headed motor 17 drives the fan 4 and the connecting plate 5 to rotate simultaneously. When the fan 4 rotates, it will draw the smoke and odor upward, so as to facilitate the filtering and purification of the smoke and odor. When the connecting plate 5 rotates, it drives the second telescopic rod 18 and the second spring 19 to move simultaneously. When the second telescopic rod 18 and the second spring 19 move simultaneously, they drive the scraper 6 to move. When the scraper 6 moves, it can scrape the surface of the dust-proof shell 3, thereby preventing the lighting lamp 2 from being affected while filtering the smoke and odor.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
