This scheme specifically relates to a building flue ventilation device with filtering function;

[0003] When the existing building flue ventilation device is in use, the long-term use of the filter will easily cause the filtered dirt to accumulate and become clogged. It needs to be fixed with bolts, which is not convenient for the quick installation and removal of the filter. In addition, the dust and dirt in the flue gas easily adhere to the inner wall of the flue body, which is not convenient to scrape and clean, which has a certain impact on actual use.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a building flue ventilation device with filtering function comprises a flue body 1, a filtering mechanism 2 is installed on the top of the flue body 1, a cleaning mechanism 3 is installed inside the flue body 1, the filtering mechanism 2 comprises four supporting columns 4, the four supporting columns 4 are installed on the top of the flue body 1, a top plate 5 is installed on the top of the four supporting columns 4, a protective cover 6 is installed on the top of the top plate 5, a positioning frame 7 is movably installed on both sides and the front and back parts of the bottom of the top plate 5, sliding grooves 8 are provided on the inner walls of both sides of the positioning frame 7, a limiting groove 9 is provided on the inside of the positioning frame 7 near the top, a card slot 10 is provided on the top of the flue body 1 near the front and rear ends and on both sides, a filter screen 11 is movably installed inside the positioning frame 7, and a push block 12 is installed on the outer side of the filter screen 11 near the bottom.

[0023] In this embodiment, the top of the positioning frame 7 is connected to the top plate 5 via a hinge, and the positioning frame 7 is located at the bottom of the top plate 5 and is movably rotatable. The rotation of the positioning frame 7 facilitates the rapid installation and removal of the filter 11.

[0024] In this embodiment, four positioning frames 7 are installed in a rectangular surrounding shape, and the filter screen 11 is slidably arranged between the two slide grooves 8. Through the four filter screens 11, the smoke is filtered through the filter screen 11 to reduce the diffusion of dust particles outward.

[0025] In this embodiment, the top of the filter screen 11 matches the limiting groove 9, and the bottom of the filter screen 11 is snap-connected with the slot 10. When the positioning frame 7 is vertical, the filter screen 11 is automatically snapped into the slot 10 under the action of gravity for quick fixation.

[0026] In this embodiment, the cleaning mechanism 3 includes a screw 13 and two fixing frames 14. The screw 13 is movably installed inside the flue body 1. A motor 15 is installed at the top of the screw 13 and on the top of the top plate 5. One of the fixing frames 14 is sleeved on the periphery of the screw 13, and the other fixing frame 14 is fixedly installed inside the flue body 1 near the bottom. Positioning frames 16 are fixedly installed on both sides and the front and back parts of the fixing frames 14 sleeved on the periphery of the screw 13. Scrapers 17 are movably installed on both sides and the front and back parts of the bottom of the positioning frame 16. Two springs 18 are connected between the top of each scraper 17 and the positioning frame 16. A collecting box 19 is installed at the bottom of the flue body 1. A door panel 20 is movably installed at the front of the collecting box 19. A positioning bolt 21 is movably installed at the bottom of the front of the door panel 20. The corresponding fixing frame 14 is driven to rise and fall by the screw 13, so that the scraper 17 scrapes off the dust adhered to the inner wall of the flue body 1.

[0027] In this embodiment, the fixing frame 14 is sleeved on the outer periphery of the screw rod 13 and is threadedly connected. The scraper 17 is connected to the positioning frame 16 by a hinge. When the fixing frame 14 descends, the outer end of the scraper 17 is attached to the inner wall of the flue body 1 for scraping. When the fixing frame 14 rises, the scraper 17 rotates and separates from the inner wall of the flue body 1.

[0028] In this embodiment, the inner surface of the collection box 19 near the bottom is inclined, and the positioning bolt 21 passes through the door panel 20 and is threadedly connected. The scraped dust is collected by the collection box 19, which is convenient for regular cleaning.

[0029] It should be noted that the utility model is a building flue ventilation device with filtering function. When in use, firstly install four filter screens 11 in the corresponding positioning frame 7, and filter the smoke discharged from the flue body 1 through the filter screen 11. When installing, rotate the positioning frame 7 to make the bottom end of the positioning frame 7 unfold outward, and then insert the filter screen 11 between the two slide grooves 8 in the positioning frame 7, so that the top of the filter screen 11 slides into the limit groove 9, and the positioning frame 7 is rotated to a vertical state, and the filter screen 11 is pushed downward or slides downward under the action of gravity and is stuck in the card slot 10, so that the positioning frame 7 is rotated to a vertical state, and then the filter screen 11 is pushed downward or slides downward under the action of gravity and is stuck in the card slot 10, so that the positioning frame 7 is rotated to a vertical state, and then the filter screen 11 is rotated to a vertical state, and then the positioning frame 7 is rotated to a vertical state, and then the positioning frame 7 is rotated to a vertical state, and then the positioning frame 7 is rotated to a vertical state, and then the positioning frame 7 is rotated to a vertical state, and then the positioning frame 7 is rotated to a vertical state, and then the positioning frame 7 is rotated to a vertical state, and then the positioning frame 7 is rotated to a vertical state, and then the positioning frame 7 is rotated to a vertical state, and then the positioning frame 7 is rotated to a vertical state, and then the positioning frame 1 ... The frame 7 and the filter screen 11 are fixed. Since the dirt such as oil droplets and dust in the flue gas adheres to the inner wall of the flue body 1, when cleaning, the screw 13 is rotated by starting the motor 15, and the corresponding fixing frame 14 is driven to slide downward. Under the action of the spring 18, the scraper 17 is unfolded and contacts the inner wall of the flue body 1 to scrape the inner wall of the flue body 1. When the fixing frame 14 slides upward, the dirt passes through the inclined scraper 17, causing the scraper 17 to rotate flexibly, and is scraped off in sequence when it descends again. The scraped dust falls into the collection box 19 for collection, and is opened through the door panel 20 for regular cleaning.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
