Description

Technical Field

[0001] This invention relates to the field of air purification, and more particularly to a clog-resistant negative ion air purification device. Background Technology

[0002] Existing negative ion air purifiers release electrons through a special circuit. These electrons combine with oxygen molecules in the atmosphere to form negative ions. The core of these devices is the generation of negative ions, which purify the air by utilizing their dust-removing, sterilizing, and detoxifying properties. However, existing negative ion purifiers only use a negative ion generator to emit negative ions for purification. This method takes a long time and has low purification efficiency. In dusty environments, a combination of filters and negative ions would be more effective. However, with filters, dust can adhere to the filter, causing blockage and reducing purification efficiency. Chinese invention patent CN111467935A provides a clog-resistant negative ion air purifier. This device generates more negative ions through rotating water spray, achieving better purification. The water injection mechanism saves water resources and keeps the water level inside the casing stable.

[0003] However, the water spraying method in the existing technology can easily make the purified air too humid, which will aggravate the air humidity in the southern region. The traditional method of dispersing negative ions has a small contact area with the air and cannot achieve a good purification effect. The effect of using negative ions to purify fine dust is not ideal, and it can easily affect the life of the negative ion generator and is difficult to clean. Therefore, there is an urgent need for such a clogging-proof negative ion air purification device. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention discloses an anti-clogging negative ion air purification device, comprising a housing, a collection box, a filter zone, an air inlet zone, a negative ion degradation zone, and an air outlet zone. Air passes through these zones sequentially and is finally discharged from the air outlet zone. A filter screen is slidably mounted in the filter zone. A cylinder is fixedly mounted on the housing, with its cylinder arm fixedly connected to the filter screen. The filter screen is arc-shaped. A cleaning plate is fixedly mounted on the lower side of the filter zone. The cleaning plate has an arc-shaped groove, with an arc-shaped rack on one side of the groove. A straight groove is located below the arc-shaped groove, with a rack on one side of the straight groove. A cleaning motor is slidably mounted in the straight groove, and a cleaning gear is fixedly mounted on the motor's shaft, meshing with the rack. A driven gear is movably mounted in the arc-shaped groove, meshing with the rack. A cleaning brush is fixedly mounted on the shaft of the driven gear, and a sliding groove is rotatably mounted on the cleaning brush. A slider is vertically slidably mounted on the sliding groove, rotatably connected to the shaft of the cleaning gear. A spring is installed between the slider and the sliding groove.

[0005] Furthermore, multiple baffles I are rotatably installed between the filtration zone and the air inlet zone. Each baffle I is fixedly equipped with a gear I. A vertical rack is slidably installed between the filtration zone and the air inlet zone, and the vertical rack meshes with all gears I. A small spring is installed between the upper end of gear I and the housing. A connecting rod is hinged to the upper end of the vertical rack, and a transverse rack is hinged to the connecting rod. The transverse rack is slidably installed on the housing. Multiple gears II mesh with the lower end of the transverse rack, and baffles II are fixedly installed on gears II. Under normal conditions, there are gaps between the multiple baffles I and there is a seal between the multiple baffles II. When the filter screen rises, the upper end of the filter screen presses against the lower end of the vertical rack, causing the vertical rack to rise. After that, the baffles I are sealed, and there are gaps between the baffles II.

[0006] Furthermore, a motor II is fixedly mounted on the housing, above multiple baffles II, and a gear VII is fixedly mounted on the shaft of the motor II. A gear VI meshes with one side of the gear VII, and a fan blade III is fixedly mounted on the lower side of the gear VI. The fan blade III rotates to blow air into the filter area.

[0007] Furthermore, the negative ion degradation zone is equipped with a connecting pipe that connects the air inlet zone and the air outlet zone. The connecting pipe is U-shaped and its bottom is close to the bottom of the box. A negative ion generator is installed inside the connecting pipe.

[0008] Furthermore, a fan blade I is installed between the filtration zone and the air intake zone.

[0009] Furthermore, a fan blade II is provided between the outer side of the housing and the air outlet area.

[0010] Furthermore, both fan blade I and fan blade II are driven by motors to assist in ventilation.

[0011] The beneficial effects of this invention compared with the prior art are: (1) The filter screen of this invention is arc-shaped, which can increase the filtration area, and the cleaning brush driven by the connecting rod cleans the filter screen, preventing the filter screen from becoming clogged due to long-term use; (2) The baffle I and baffle II set in this invention can control ventilation or not ventilation. During the cleaning of the filter screen, baffle I is closed to prevent dust from flying into the air intake area and affecting subsequent steps, and also to protect the negative ion generator. (3) This invention can blow air onto the filter screen to blow the dust that has not been brushed off into the collection box, further preventing the filter screen from becoming clogged; (4) The connecting pipe of this invention is a U-shaped pipe, and a negative ion generator is set in the connecting pipe, which can purify the air with negative ions over a long distance and ensure the purification effect.

Detailed Implementation

[0027] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] Example: A clog-resistant negative ion air purifier includes a housing 48, which contains a collection box 1, a filter zone 3, an air inlet zone 4, a negative ion degradation zone 6, and an air outlet zone 5. Air passes through these zones sequentially and is finally discharged from the air outlet zone 5. The filter zone 3 contains a filter screen 8 for initial filtration. A connecting pipe 42 connects the air inlet zone 4 and the air outlet zone 5. A negative ion generator 43 is installed in the connecting pipe 42 to remove harmful substances from the air. The air is then discharged through the air outlet zone 5, thus completing the purification process.

[0029] The filter zone 3 is equipped with a pressure sensor 21. A filter screen 8 is vertically slidably mounted in the filter zone 3. A cylinder 7 is fixedly mounted on the housing 48. The cylinder arm of the cylinder 7 is fixedly connected to the filter screen 8. The cylinder 7 drives the filter screen 8 to move up and down. The filter screen 8 is arc-shaped to increase the filtration area. A cleaning plate 9 is also fixedly mounted in the filter zone 3. The cleaning plate 9 is provided with an arc-shaped groove 15. An arc-shaped rack 14 is provided on the arc-shaped groove 15. The arc-shaped rack 14 and the arc-shaped groove 15 are adapted to the shape of the filter screen 8. A straight groove 16 is provided on the lower side of the arc-shaped groove 15. A rack 12 is provided on one side of the straight groove 16. A cleaning motor 10 is slidably mounted in the straight groove 16. A cleaning gear 11 is fixedly mounted on the rotating shaft of the filter 10. A slider 18 is rotatably mounted on the cleaning gear 11. The cleaning gear 11 meshes with the rack 12. A driven gear 13 is fitted in the arc-shaped groove 15. The driven gear 13 meshes with the arc-shaped rack 14. A cleaning brush 17 is fixedly mounted on the shaft of the driven gear 13. A sliding groove 20 is rotatably mounted on the cleaning brush 17. The sliding groove 20 is slidably connected to the slider 18. A spring 19 is fixedly mounted between the slider 18 and the sliding groove 20. When the cleaning motor 10 is started, the cleaning motor 10 slides in the straight groove 16. Through the slider 18 and the sliding groove 20, the cleaning brush 17 is driven to rotate and slide in the arc-shaped groove 15, thereby cleaning the filter screen 8.

[0030] Multiple baffles I 28 are rotatably mounted between the filter zone 3 and the air inlet zone 4. Multiple baffles II 29 are rotatably mounted between the collection box 1 and the outside of the box body 48. Gear I 23 is fixedly mounted on baffle I 28, and gear II 27 is fixedly mounted on baffle II 29. A vertical rack 22 is slidably mounted on the box body 48, and the vertical rack 22 meshes with gear I 23. The upper end of the vertical rack 22 is connected to the box body 48 through a small spring 24. A connecting rod 25 is hinged to the upper end of the vertical rack 22, and a horizontal rack 26 is hinged to the connecting rod 25. The horizontal rack 26 is slidably mounted on the box body. On body 48, the transverse rack 26 meshes with gear II 27. During normal use, there are gaps between all baffles I 28 and all baffles II 29 are sealed. Air enters the air intake area 4 from the filter area 3 for filtration and removal. When the filter screen 8 is clogged with dust, it is cleaned by the cleaning brush 17 and then rises. After the filter screen 8 rises to the designated position, its upper end contacts the lower end of the vertical rack 22 and drives the vertical rack 22 to rise. The vertical rack 22 drives the transverse rack 26 to slide. At this time, the baffles I 28 are sealed and there are gaps between the baffles II 29.

[0031] A motor II 44 is fixedly mounted on the housing 48. The motor II 44 is located above the baffle II 29. A gear VII 47 is fixedly mounted on the shaft of the motor II 44. A fan blade III 46 is meshed on one side of the gear VII 47. The fan blade III 46 is rotatably mounted on the housing 48. The fan blade III 46 is fixedly mounted on the gear VI 45. When the motor II 44 is started, it drives the fan blade III 46 to rotate. The fan blade III 46 blows air towards the filter screen 8, blowing the dust attached to the filter screen 8 downwards and into the collection box 1. An air outlet 50 is provided at the top of the housing 48. The air outlet 50 allows air to enter so that the fan blade III 46 can blow air onto the filter screen 8.

[0032] The negative ion degradation zone 6 is equipped with a connecting pipe 42, which connects the air inlet zone 4 and the air outlet zone 5. The connecting pipe 42 is U-shaped, with its bottom close to the bottom of the housing 48. A negative ion generator 43 is installed inside the connecting pipe 42. A fan blade I 36 is installed between the filtration zone 3 and the air inlet zone 4. A fan blade II 41 is installed between the outer side of the housing 48 and the air outlet zone 5. A motor I 30 is fixedly mounted on the housing 48. A gear III 31 is fixedly mounted on the shaft of the motor I 30. Gears IV 32 and V 37 mesh on both sides of gear III 31. A bevel gear I 34 is fixedly mounted on gear IV 32 through shaft I 33. A bevel gear II 35 meshes on one side of bevel gear I 34. Bevel gear II 35 is fixedly connected to fan blade I 36. A gear V 37 is connected to the fan blade I 36 through a rotating shaft I 33. Shaft II 38 is fixedly equipped with bevel gear III 39, and bevel gear IV 40 meshes with one side of bevel gear III 39. Bevel gear IV 40 is fixedly connected to fan blade II 41. The air filtered by dust is sent into the air inlet zone 4 through fan blade I 36. Negative ions are generated in the air inlet zone 4 through the negative ion generator 43 in the connecting pipe 42 to remove harmful substances. Finally, the purified air is discharged from the box 48 through fan blade II 41. An air inlet plate 2 is set on one side of the collection box 1 for air intake. A heat dissipation mesh 49 is set on the box 48 to dissipate part of the heat for the negative ion degradation zone 6.

[0033] Working principle: Under normal conditions, motor I30 is started, which drives gear III31, which in turn drives gears IV32 and V37 to rotate. This, in turn, drives fan blades I36 and II41 to rotate via bevel gears. Air enters through the air inlet plate 2, is filtered by the filter screen 8, and then drawn into the air inlet zone 4 by fan blade I36. The air is further purified by the negative ion generator 43 through the connecting pipe 42, and then discharged from the air outlet zone 5 by fan blade II41, completing the purification process. During long-term use, the filter screen 8 inevitably becomes clogged. The air pressure sensor 21 detects an increase in air pressure within the filter zone 3. At this time, cylinder 7 is activated, causing the filter screen 8 to descend and contact the cleaning brush 17. Then, the cleaning motor 10 is activated. The cleaning motor 10 slides within the straight groove 16 through the cooperation of the cleaning gear 11 and rack 12, driving the vertical gears... As the cleaning brush 17 moves, the spring 19 is compressed, and the cleaning brush 17 moves with the spring 19. The passive gear 13 on the cleaning brush 17 cooperates with the arc-shaped rack 14, causing the cleaning brush 17 to rotate and move, cleaning the dust on the filter screen 8. The dust falls into the collection box 1. The reverse start cylinder 7 drives the filter screen 8 to rise. The upper end of the filter screen 8 finally contacts the lower end of the vertical rack 22, driving the vertical rack 22 to rise and drive the gear I 23 to rotate. All the baffles I 28 close together. The vertical rack 22 drives the horizontal rack 26 to slide through the connecting rod 25. The horizontal rack 26 drives the gear II 27 to rotate. The gear II 27 drives the baffles II 29 to open the gap. Then the motor II 44 is started. The motor II 44 drives the gears VII 47, VI 45 and the fan blade III 46 to rotate, further blowing the dust on the filter screen 8 into the collection box 1.
