Description

Technical Field

[0002] An air filter refers to an air filtering device, which is generally used in clean workshops, clean factories, laboratories and clean rooms, or for dust prevention of electronic machinery communication equipment, etc.

[0003] For the cleaning of the filter screen in the existing indoor air filter, the filter screen needs to be removed first, and then reinstalled after cleaning. During the disassembly and assembly process, the air filter cannot be used continuously. There are also those that clean the dust and impurities on the surface of the filter screen during the operation of the air filter. However, the cleaned dust and impurities are easily reattached to the surface of the filter screen, resulting in poor cleaning effect on the surface of the filter screen. Moreover, the cleaned dust and impurities still remain in the air environment. If only various filter layers are used to filter the air, the dust and impurities in the air are likely to cause frequent replacement of the filter layer, resulting in a relatively high daily use cost of the air filter.

[0017] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further introduced in detail below with reference to the accompanying drawings.

[0018] Embodiment: Please refer to Figure 1 - Figure 7 , an indoor air filter, including a body 1 and an air duct 2 installed on the inner wall of one side of the body 1, and further including: a first partition 3, which is installed inside the body 1, a rotating cylinder 4 is installed on the top of the first partition 3, two through openings are provided on the outer wall of the rotating cylinder 4, and a filter screen 5 is installed inside the through openings; a wind guiding mechanism, which includes an air extraction pipe 6 installed inside the first partition 3 and a negative pressure fan 7 installed inside the air extraction pipe 6, the air extraction pipe 6 is located inside the rotating cylinder 4, and the air inlet end faces the air duct 2; By starting the negative pressure fan 7, the indoor air enters the inside of the air extraction pipe 6 through the air duct 2 and the right filter screen 5, and the filter screen 5 filters the dust and impurities in the air.

[0019] A driving mechanism, which is installed on the top of the first partition 3 and is used to drive the rotating cylinder 4 to rotate. The driving mechanism includes a gear ring 17 fixedly sleeved outside the rotating cylinder 4 and a motor 18 installed at the bottom of the first partition 3. The output end of the motor 18 is fixedly connected with a gear 19, and the gear 19 meshes with the gear ring 17; When it is necessary to replace the filter screen 5 on the right side, the motor 18 is controlled to drive the gear 19 to rotate. Through the meshing effect between the gear 19 and the gear ring 17, the rotating cylinder 4 is driven to rotate 180°, so that another filter screen 5 rotates to the left side of the air duct 2, and then the filter screen 5 is replaced to filter the air.

[0020] The second partition plate 8 is installed inside the machine body 1, and the top of the rotating cylinder 4 is rotatably connected to the bottom of the second partition plate 8; The linkage air control mechanism includes an air cylinder 9 installed at the bottom of the second partition plate 8, a first piston 10 installed inside the air cylinder 9, and a lifting frame 11 installed on the top of the first piston 10. A damping spring 20 is installed at the bottom of the air cylinder 9, and the top end of the damping spring 20 is connected to the bottom of the first piston 10. A side of the top of the air cylinder 9 is provided with an air inlet pipe 21, and a first one-way valve 22 is installed on the air inlet pipe 21. The setting of the first one-way valve 22 enables external air to enter the inside of the air cylinder 9 through the air inlet pipe 21, and the air inside the air cylinder 9 cannot be discharged through the air inlet pipe 21; When the rotating cylinder 4 rotates to the point where the through hole on the right side is completely disconnected from the air duct 2, the incomplete sealing cylinder 14 seals the through hole. At this time, the rotating cylinder 4 is sealed. As the negative pressure fan 7 continues to operate, the first piston 10 is driven to move downward along the inner wall of the air cylinder 9, and the damping spring 20 is compressed accordingly. Air is pumped into the inside of the air cylinder 9 through the air inlet pipe 21, and at the same time, the lifting frame 11 is driven to move downward; After another filter screen 5 rotates to the left side of the air duct 2, the solenoid valve 29 is controlled to open. Through the resilience of the damping spring 20, the first piston 10 is driven to move upward slowly, and the air inside the air cylinder 9 is gradually discharged through the air guide hose 28. After the air inside the air cylinder 9 is completely discharged, the solenoid valve 29 is controlled to close.

[0021] The cleaning mechanism includes a first housing 12 installed on the inner wall of the other side of the machine body 1 and an elastic telescopic scraper 13 installed inside the first housing 12. The bottom end of the lifting frame 11 extends into the inside of the first housing 12 and is fixedly connected to the top of the elastic telescopic scraper 13. A dust guide port 23 is opened inside the elastic telescopic scraper 13, and a dust guide hose 24 is installed at the bottom of the elastic telescopic scraper 13; inclined slots are opened at the top and bottom of one end of the elastic telescopic scraper 13 close to the second housing 15, and one end of the elastic telescopic scraper 13 is adapted to the outer wall of the filter screen 5; the elastic telescopic scraper 13 includes a sliding seat slidably connected inside the first housing 12, a chute opened inside the other end of the sliding seat, and a slider slidably connected inside the chute. A plurality of springs are fixedly connected inside the chute, and the other ends of the springs are fixedly connected to the outer wall of the slider; When the first piston 10 drives the lifting frame 11 to move downward, it drives the elastic telescopic scraper 13 to move downward synchronously along the outer wall of the rotating cylinder 4. When the right filter screen 5 rotates to the right side of the first housing 12, due to the elastic action of the elastic telescopic scraper 13, one end of the elastic telescopic scraper 13 abuts against the outer wall of the filter screen 5. When the lifting frame 11 moves upward, it drives the elastic telescopic scraper 13 to move upward synchronously along the outer wall of the filter screen 5 to scrape off the dust and impurities on the outer wall of the filter screen 5. And when the inclined groove at the top of the elastic telescopic scraper 13 abuts against the upper edge of the through port, the elastic telescopic scraper 13 moves to the right and separates from the filter screen 5 and abuts against the outer wall of the rotating cylinder 4, without affecting the subsequent rotation of the rotating cylinder 4.

[0022] The directional dust removal mechanism includes an incomplete sealing cylinder 14 fixedly connected to the bottom of the second partition plate 8, a second housing 15 fixedly connected to the outer wall of one side of the incomplete sealing cylinder 14, and a nozzle 16 installed inside the second housing 15. The outer wall of the incomplete sealing cylinder 14 abuts against the inner wall of the rotating cylinder 4. The top of the nozzle 16 is fixedly connected to a driven rod 25, and the top end of the driven rod 25 extends to the outside of the second housing 15. When the lifting frame 11 moves downward and abuts against the top end of the driven rod 25, it drives the driven rod 25 and the nozzle 16 to move downward; a linkage rod 26 is installed at the bottom of the nozzle 16, a return spring 27 is sleeved outside the linkage rod 26, the top end of the return spring 27 is fixedly connected to the bottom of the nozzle 16, and the bottom end of the return spring 27 is fixedly connected to the inner wall of the bottom of the second housing 15. The bottom end of the linkage rod 26 extends to the outside of the second housing 15; a gas guide hose 28 is also installed at the top of the nozzle 16, the other end of the gas guide hose 28 is connected to the top of the air cylinder 9, and a solenoid valve 29 is installed on the gas guide hose 28; When the first piston 10 drives the lifting frame 11 to move downward, after the lifting frame 11 descends a certain distance, it abuts against the top end of the driven rod 25 and starts to drive the driven rod 25 to move downward. The nozzle 16 and the linkage rod 26 move downward accordingly, and the return spring 27 is compressed. Since the nozzle 16 starts to descend after the lifting frame 11 descends a certain distance, after the nozzle 16 descends, its lower edge is at the same horizontal height as the upper edge of the elastic telescopic scraper 13. Thus, when the lifting frame 11 moves upward, the elastic telescopic scraper 13 moves upward synchronously. During the process of scraping the surface of the filter screen 5, the return spring 27 drives the nozzle 16 to move upward synchronously by its rebounding force, and the lower edge of the nozzle 16 is at the same horizontal height as the upper edge of the elastic telescopic scraper 13. Furthermore, the air discharged from the inside of the air cylinder 9 blows towards the top of the elastic telescopic scraper 13 through the gas guide hose 28 and the nozzle 16, and the scraped dust and impurities are blown off the surface of the filter screen 5 in a directional manner. The blown-off dust and impurities are directly discharged into the dust settling tank 30 through the dust guide hose 24.

[0023] On the inner wall at the bottom of the body 1, a deep dust removal mechanism is installed. The deep dust removal mechanism includes a dust settling tank 30 installed on the inner wall at the bottom of the body 1 and a water control tank 31 arranged on one side of the dust settling tank 30; the bottom end of the dust guiding hose 24 extends into the interior of the dust settling tank 30; on the inner wall at the top of the dust settling tank 30, a spraying assembly 41 is installed; inside the water control tank 31, a second piston 32 is installed. The bottom end of the linkage rod 26 extends into the interior of the water control tank 31 and is fixedly connected to the top of the second piston 32. On the top of the water control tank 31, a water guiding pipe 33 is installed. The other end of the water guiding pipe 33 is connected to the spraying assembly 41. A second one-way valve 36 is installed on the water guiding pipe 33. The setting of the second one-way valve 36 enables the water inside the water control tank 31 to be supplied to the spraying assembly 41 through the water guiding pipe 33, and the water inside the spraying assembly 41 cannot flow back into the water control tank 31 through the water guiding pipe 33. On the inner wall at the bottom of the body 1, a water storage tank 34 is also installed. Between the top of the water control tank 31 and the bottom of the water storage tank 34, they are connected through a water supply pipe 37. A third one-way valve 38 is installed on the water supply pipe 37. The setting of the third one-way valve 38 enables the water inside the water storage tank 34 to enter the water control tank 31 through the water supply pipe 37, and the water inside the water control tank 31 cannot flow back into the water storage tank 34 through the water supply pipe 37; on one side at the bottom of the body 1, a sewage tank 35 is installed. On the top of the sewage tank 35, a sewage discharge pipe 42 is installed. The sewage discharge pipe 42 is connected to the dust settling tank 30. On the top of the dust settling tank 30, a return pipe 39 is installed. The return pipe 39 is connected to the air extraction pipe 6; on the inner wall at the bottom of the body 1, a filter layer 40 is also installed. The bottom end of the air extraction pipe 6 is connected to the filter layer 40. The filter layer 40 can not only filter the residual dust impurities but also adsorb the bacteria in the air; When the linkage rod 26 moves downward, it drives the second piston 32 to move downward along the inner wall of the water control tank 31, pumping the water inside the water storage tank 34 into the water control tank 31 through the water supply pipe 37. During the process that the linkage rod 26 drives the second piston 32 to move upward, water is supplied to the spraying assembly 41 through the water guiding pipe 33. Thus, during the process that the dust guiding hose 24 discharges the dust impurities into the interior of the dust settling tank 30, the spraying assembly 41 performs dust settling treatment on the dust impurities discharged into the interior of the dust settling tank 30. The air after the dust settling treatment enters the interior of the air extraction pipe 6 through the return pipe 39 and is discharged into the interior of the filter layer 40 together with the air filtered by the filter net 5 inside the air extraction pipe 6 for further air filtration treatment.

[0024] Working principle: When in use, start the negative pressure fan 7 to draw the indoor air into the inside of the exhaust pipe 6 through the air duct 2 and the filter screen 5 on the right side. The filter screen 5 filters the dust and impurities in the air. After the air filter runs for a long time, a large amount of dust and impurities will accumulate on the surface of the filter screen 5, resulting in a slower air passing speed. By controlling the motor 18 to drive the gear 19 to rotate, through the meshing effect between the gear 19 and the gear ring 17, the rotating cylinder 4 is driven to rotate 180°, so that another filter screen 5 rotates to the left side of the air duct 2, and then the filter screen 5 is replaced to filter the air. During this process, when the rotating cylinder 4 rotates to the right through-hole and is completely disconnected from the air duct 2, the incomplete sealing cylinder 14 seals the through-hole. At this time, the rotating cylinder 4 is sealed. With the continuous operation of the negative pressure fan 7, the first piston 10 is driven to move downward along the inner wall of the air cylinder 9, and the damping spring 20 is compressed accordingly. The air is drawn into the inside of the air cylinder 9 through the air inlet pipe 21. At the same time, the lifting frame 11 is driven to move downward. When the lifting frame 11 moves downward, the elastic telescopic scraper 13 is driven to move downward synchronously along the outer wall of the rotating cylinder 4. When the filter screen 5 on the right side rotates to the right side of the first housing 12, through the elastic action of the elastic telescopic scraper 13, one end of the elastic telescopic scraper 13 abuts against the outer wall of the filter screen 5. At the same time, after the lifting frame 11 descends a certain distance, it abuts against the top end of the driven rod 25 and starts to drive the driven rod 25 to move downward. The air nozzle 16 and the linkage rod 26 move downward accordingly, and the return spring 27 is compressed. Since the air nozzle 16 starts to descend after the lifting frame 11 descends a certain distance, the lower edge of the air nozzle 16 is at the same horizontal height as the upper edge of the elastic telescopic scraper 13 after the air nozzle 16 descends. Therefore, when the lifting frame 11 moves upward, the elastic telescopic scraper 13 moves upward synchronously. During the process of scraping the dust on the surface of the filter screen 5, the air nozzle 16 is driven to move upward synchronously by the rebounding force of the return spring 27, and the lower edge of the air nozzle 16 is at the same horizontal height as the upper edge of the elastic telescopic scraper 13. Furthermore, the air discharged from the inside of the air cylinder 9 blows towards the top of the elastic telescopic scraper 13 through the air guide hose 28 and the air nozzle 16, and the scraped dust and impurities are directed to be blown off the surface of the filter screen 5. The blown dust and impurities are directly discharged into the dust settling tank 30 through the dust guide hose 24. The dust settling component 41 performs dust settling treatment on the dust and impurities discharged into the dust settling tank 30. The air after dust settling treatment enters the inside of the exhaust pipe 6 through the return pipe 39, and is discharged into the filter layer 40 together with the air filtered by the filter screen 5 inside the exhaust pipe 6 for further air filtration treatment.
