A humidifying mechanism, including a humidifying pipe 2, is fixed at the rear end of the exhaust box 1. A valve mechanism, including a fan plate 8, is fixed at the rear end of the exhaust box 1. Moving the telescopic inner rods 6 causes the two side stop blocks 25 to move away from the exhaust box 1, so that the stop blocks 25 abut against the inner walls of both sides of the window, thus completing the fixation.

[0022] refer to Figure 4 The telescopic inner rod 6 has a locking hole 601 on the side of its outer circumference away from the abutment block 25. A second support spring 23 is fixed to the bottom inner wall of the locking hole 601. A connecting plate 18 is welded to the top of the second support spring 23, and a semi-circular protrusion 19 is engaged with the top of the connecting plate 18. Limiting holes 401 are evenly distributed on the outer circumference of the telescopic outer tube 4, and the limiting holes 401 and the semi-circular protrusion 19 are compatible. By engaging the semi-circular protrusion 19 with the limiting holes 401 at different positions, the extension length of the telescopic inner rod 6 can be controlled, thereby changing the distance between the two abutment blocks 25. This is suitable for different windows and meets the needs of different spaces. Users can place it in the place where purification is most needed, which enhances the product's market competitiveness.

[0023] refer to Figure 4 Each loading hole 101 has a movable hole 103 on the side away from the abutment block 25. A gasket 21 is fixed to the inner wall of the movable hole 103 on the side away from the telescopic outer tube 4. A support spring 20 is welded to the side of the gasket 21 near the telescopic outer tube 4, and a second gasket 22 is welded to the side of the support spring 20 near the telescopic outer tube 4. By setting the support spring 20, it is ensured that the abutment block 25 can fit tightly against the inner walls of both sides of the window, improving the support force and providing a certain buffering capacity, avoiding hard contact between the telescopic outer tube 4 and the exhaust box 1, and improving the safety of the device.

[0024] refer to Figure 3The exhaust mechanism includes a fixed frame 3. The fixed frame 3 is fixed to the front center of the exhaust box 1 by bolts.

A retaining strip 5 is engaged at the end of the curtain 24 away from the roller 16, and a limiting post 17 is evenly fixed at the end of the retaining strip 5 near the abutment 25. A retaining groove 2501 is evenly opened at the end of the abutment 25 near the retaining strip 5, and the retaining groove 2501 and the limiting post 17 are compatible. By setting the curtain 24, the gap between the exhaust box 1 and the abutment 25 can be sealed, preventing air from flowing through the gap and allowing outside air that may carry pollutants, dust, and pollen to mix into the room, which would reduce the purifier's efficiency.

[0026] refer to Figure 3 The filtration mechanism includes a roller 28. A loading hole 3 106 is opened on one side of the exhaust box 1 near the bottom rear end, and the roller 28 is inserted into the inner wall of one side of the loading hole 3 106.

Movable grooves 105 are opened on both sides of the exhaust box 1 near the top of the loading hole 3 106, and a locking hole 104 is opened on the inner wall of one end of the movable groove 105 near the top. The locking hole 104 and the locking rod 27 are compatible. Dragging the locking rod 27 moves the locking rod 27 to engage with the locking hole 104, raising the filter cloth 10, which can complete the filtration of the exchanged air. According to different needs, filter cloths 10 with different pore sizes and effects can be replaced to provide targeted filtration methods to meet the needs of different groups of people.

[0027] refer to Figure 7The humidification mechanism includes a humidification pipe 2. The humidification pipe 2 is snapped onto the top of the exhaust box 1 near the movable slot 105, and a water inlet pipe 26 is inserted into one side of the humidification pipe 2. A water outlet slot 202 is opened on the inner circumference of the humidification pipe 2 near the bottom, and the water outlet slot 202 is connected to the movable slot 105. A separation pipe 36 is rotatably inserted into the inner circumference of the humidification pipe 2 away from the water inlet pipe 26, and water outlet holes 3601 of different diameters are evenly opened on the outer circumference of the separation pipe 36. A sliding rod 37 is snapped onto the outer circumference of the separation pipe 36 near the middle of the top, and a sliding hole 201 is opened on the outer circumference of the humidification pipe 2 near the middle of the top, and the sliding hole 201 and the sliding rod 37 are compatible. By setting water outlet holes 3601 of different diameters, different water output speeds can be controlled to wet the filter cloth 10, thereby adjusting the air humidity.

[0028] refer to Figure 6 A cleaning groove 107 is provided at the rear end of the exhaust box 1 near the bottom, and a scraper 30 is inserted into the cleaning groove 107. A base plate 31 is fixed to the end of the scraper 30 away from the exhaust box 1 near both sides by bolts.

A limit bolt 35 is screwed to the middle of one end of the fixing plate 34. By setting the scraper 30, when tightening, the filter cloth 10 can be wound up so that the scraper 30 can scrape the surface of the filter cloth 10, clean the water stains or contaminants on the surface of the filter cloth 10, and ensure the purity of the filter cloth 10.

[0029] refer to Figure 8 The valve mechanism includes a loading plate 38. The rear end of the exhaust box 1 is bolted to the loading plate 38. A second rotating shaft 42 is evenly inserted into the inner circumference of the end of the loading plate 38 furthest from the exhaust box 1. A fan plate 8 is rotatably connected to the outer circumference of each rotating shaft 42. A first rotating shaft 40 is inserted into the arc-shaped outer wall of each fan plate 8 furthest from the loading plate 38. A connecting arm 41 is rotatably connected to the outer circumference of each rotating shaft 40. A third rotating shaft 43 is inserted into the end of each connecting arm 41 furthest from the first rotating shaft 40. The loading plate 38... Fixed posts 39 are evenly inserted at the end away from the exhaust box 1 and offset from the fan plate 8. The outer circumference of several fixed posts 39 is rotatably connected to the same rotating ring 7. One end of the rotating ring 7 is evenly opened with connecting holes near the inner circumference, and the connecting holes are connected to the rotating shaft 43. By setting the fan plate 8, users can select the appropriate ventilation rate according to the room size and air quality to achieve the best purification effect. When the air quality is good, the ventilation rate can be reduced to reduce energy consumption, keep quiet, and extend the service life of the filter.

[0030] Working principle: First, move the device to the exhaust window where air purification is needed, pull out the telescopic inner rod 6, and let the abutment 25 abut against the inner walls on both sides of the window to complete the initial fixation. Then, change the connection position of the limiting hole 401 and the semi-circular protrusion 19 so that the telescopic outer tube 4 squeezes the support spring 20 to complete the final fixation. When only ventilation is needed, roll up the filter cloth 10 to avoid the filter cloth 10 from obstructing the ventilation rate. When air filtration is needed, drag the clamp 27 into the clamp hole 104 to raise the filter cloth 10 and complete the filtration. After injecting clean water along the water injection pipe 26, wet the filter cloth 10 to increase the humidity of the circulating air. Rotate the slide rod 37 to adjust the water outlet holes 3601 of different diameters to fit with the water outlet tank 202 so that the filter cloth 10 has different wettability and changes the indoor air humidity. Rotate the rotating ring 7 to make the fan plate 8 rotate along the rotating shaft 42 to change the closure degree of each fan plate 8 and adjust the ventilation rate of the device.
