They primarily remove particulate matter through filtration, adsorption, and combined technologies, which can improve air quality to some extent. However, the purification effect of existing devices still has room for improvement and is insufficient to meet increasingly stringent air quality requirements and people's high demands for healthy breathing. Summary of the Invention

[0004] This invention provides an air purification device and method, aiming to solve the problem of poor purification effect of current air purification devices mentioned in the background art.

[0008] Preferably, the rotary exhaust mechanism includes: an exhaust pipe rotatably mounted on the exhaust pipe via a sealed bearing, wherein a first ball bearing is embedded at the bottom edge of the exhaust pipe and the first ball bearing contacts an annular groove on the exhaust pipe; a first gear fixedly sleeved on the exhaust pipe; a second transmission rod rotatably mounted in the housing via a sealed bearing, wherein a second gear meshing with the first gear is fixedly mounted on the second transmission rod; and second bevel teeth fixedly mounted on the second transmission rod and the first transmission rod respectively and meshing with each other.

[0009] Preferably, staggered baffles are fixedly installed inside the partition frame to separate the air passages, the air passages are interconnected, and a number of air holes are opened on the air guide shell.

[0010] Preferably, the filter box is provided with a filter bag for filtering impurities, a sealing plate is fixed to one side of the filter box by screws, the filter bag is detachably installed in the filter box, the filter plate is at least one of HEPA filter plate or activated carbon filter plate, and the filter plate is detachably connected to the partition frame.

[0011] Preferably, a shield is fixedly installed on the top of the housing by bolts, and the shield has an opening adapted to the air outlet pipe. The shield is used to shield and protect the first gear and the second gear.

[0012] Preferably, the planting box has at least one layer of mesh plate, and the filter material carried on the mesh plate is at least one of activated carbon particles, quartz sand or ceramsite, and the green plants planted in the planting cup are herbaceous plants with air purification function.

[0013] Preferably, an insect-proof net cover is fixedly installed on the planting box to protect the green plants, and a drain pipe for draining accumulated water is fixedly connected to the bottom of the box, with a valve installed on the drain pipe.

[0014] Preferably, a method for using an air purification device includes the following steps: Step 1: Start the motor inside the chamber. The motor output shaft drives the first transmission rod to rotate. The first transmission rod drives the first rotating rod to rotate through the meshing first bevel teeth, which in turn drives the fan blades inside the air guide shell to rotate, creating a negative pressure around the air guide shell and guiding the outside air into the purification process. Step 2: External air first enters the planting box, passes through the insect-proof net, and comes into contact with the green plants in the planting cup. The green plants absorb some of the pollutants in the air, and then the air is discharged through the air holes on the planting cup. Next, it undergoes preliminary filtration through the filter material carried on the mesh plate to remove large particulate impurities in the air. Step 3: The air, after being initially purified by the planting box, enters the filter box through a duct. The filter bag inside the filter box further filters out fine impurities, and then enters the box through the air inlet pipe. Step 4: The air entering the chamber enters the air guide shell through the air holes on the air guide shell. Under the guidance of the fan blades, it flows into the interlaced air channels in the partition frame. During the flow of the air in the air channels, the air passes through the filter plate for deep filtration in sequence to remove fine particulate matter such as PM2.5 and PM10. At the same time, the germicidal lamp is activated to sterilize and disinfect the air, completing the deep purification. Step 5: The deeply purified air enters the exhaust pipe at the top of the chamber. At the same time, the first transmission rod drives the second transmission rod to rotate through the meshing second bevel teeth. The second transmission rod drives the exhaust pipe to rotate around the exhaust pipe through the meshing of the second gear and the first gear, so that the purified air is evenly discharged to the external environment through the rotating exhaust pipe. Step Six: During the purification process, if water accumulates inside the chamber, open the valve on the bottom drain pipe to drain the water. When the filter bag inside the filter chamber is clogged or malfunctions, remove the sealing plate on one side of the filter chamber and replace it with a new filter bag to ensure filtration efficiency.

[0015] Compared with related technologies, the air purification device and method provided by the present invention have the following beneficial effects: The filter media carried by the mesh plate inside the planting box works in conjunction with the purifying green plants inside the planting cup to achieve initial natural purification and physical filtration of the air. The filter bag inside the filter box further intercepts impurities, and together with the filter plate in the partition frame and the germicidal lamp, it forms a multi-stage purification process to effectively improve air cleanliness. The motor drives the fan blades of the air guiding mechanism to guide the airflow, the exhaust pipe of the rotating exhaust mechanism to evenly exhaust air, and the cleaning brush of the cleaning mechanism to clean the insect-proof net cover through transmission components such as the first transmission rod and the second transmission rod, thus achieving power reuse and simplified structure. The angle adjustment of the air guide plate of the sweeping mechanism is combined with the rotation of the exhaust pipe to expand the coverage of clean air. The shield and protective shell ensure the stability of the transmission components, and the drain pipe prevents water accumulation. Attached Figure Description

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This invention provides an air purification device comprising: a housing 1; an air inlet pipe 2 fixedly connected to one side of the housing 1, the air inlet end of the air inlet pipe 2 being fixedly connected to a filter box 4; a planting box 5 fixedly installed on the housing 1 and fixedly connected to the filter box 4 via a conduit 6; the planting box 5 being provided with a mesh plate 7 for separating space and carrying filter material and a planting cup 8 for planting green plants; an exhaust pipe 20 fixedly connected to the top of the housing 1 for discharging purified air; a purification mechanism disposed within the housing 1 for deep air purification; and a rotary exhaust mechanism disposed on the exhaust pipe 20.

[0020] In this embodiment, during use, the power component of the purification mechanism inside the box 1 is activated, which drives the airflow. External air first enters the planting box 5. The mesh plate 7 inside the planting box 5 carries the filter material to perform preliminary adsorption and filtration of the air. At the same time, the green plants in the planting cup 8 adsorb some pollutants in the air, so that the air completes the preliminary purification. The preliminarily purified air enters the filter box 4 through the duct 6. The filter structure inside the filter box 4 further filters the air and removes impurities from the air. Then the air enters the interior of the box 1 through the air inlet pipe 2. The air entering the chamber 1 is guided by the purification mechanism into the deep purification zone. The filter components in the purification mechanism perform fine filtration of the air, removing fine particulate matter such as PM2.5 and PM10. At the same time, the sterilization components in the purification mechanism sterilize the air, making the air cleaner. The air that has completed deep purification enters the exhaust pipe 20. The rotary exhaust mechanism on the exhaust pipe 20 starts to work, driving the air outlet component to rotate and diffuse the purified air into the surrounding space. Throughout the purification process, the greenery in planting box 5 works in conjunction with the filter media to combine natural purification with physical filtration, enhancing the initial purification effect. The multi-stage processing of the purification mechanism further improves air cleanliness, and the rotating exhaust mechanism allows the purified air to be distributed more evenly within the usable space, reducing local air quality differences. Through reasonable connection and cooperation, the various components form a coherent purification process.

[0021] In a further preferred embodiment of the present invention, the purification mechanism includes: an assembly plate 9 fixedly installed inside the housing 1 and having through holes; an air guide shell 10 fixed to the assembly plate 9 by bolts; a partition frame 11 fixed inside the housing 1 to separate the air guide channel; and a filter plate 12 and a germicidal lamp 13 disposed inside the partition frame 11.

[0022] In this embodiment, when in use, the air entering the housing 1 through the air inlet pipe 2 first comes into contact with the assembly plate 9. The through holes on the assembly plate 9 provide a flow path for the air and guide the air to the air guide shell 10. The air guide shell 10 is fixed to the assembly plate 9 by bolts. Its structure plays a role in gathering and guiding the air, so that the air can enter the subsequent purification stage more concentratedly, reducing the disorderly diffusion of air in the housing 1 and improving the purification efficiency. Air guided by the air guide shell 10 enters the partition frame 11, which separates independent air guide channels within the housing 1. As the air flows along the air guide channels, it passes through the filter plate 12 and the germicidal lamp 13 in sequence. The filter plate 12 performs fine filtration of fine particulate matter such as PM2.5 and PM10 in the air, while the germicidal lamp 13 is activated to sterilize the air. Through the synergistic effect of filtration and sterilization, the cleanliness of the air is further improved. In the entire purification mechanism, the cooperation between the assembly plate 9 and the air guide shell 10 ensures smooth airflow and avoids air stagnation; the air guide channel formed by the partition frame 11 ensures that the air can fully contact the filter plate 12 and the germicidal lamp 13, improving the sufficiency of filtration and sterilization; the components are fixedly installed to form a stable purification unit, which works in conjunction with other structures in the housing 1 to further optimize the overall purification process and provide a reliable guarantee for the subsequent rotary exhaust mechanism to discharge clean air, which is suitable for air quality improvement needs in multiple scenarios.

[0023] In a further preferred embodiment of the present invention, the purification mechanism further includes an air guiding mechanism, which includes: a first rotating rod 15 rotatably mounted on the air guiding shell 10 via a sealed bearing; a fan blade 16 fixed on the first rotating rod 15; a motor 17 disposed in the housing 1, the output shaft of the motor 17 being fixed to a first transmission rod 18 via a coupling; and a first bevel tooth 19 respectively fixed on the first transmission rod 18 and the first rotating rod 15 and meshing with each other.

[0024] In this embodiment, when in use, the motor 17 inside the housing 1 is started, and the output shaft of the motor 17 drives the first transmission rod 18 to rotate through the coupling; since the first bevel gear 19 is fixed on the first transmission rod 18 and the first rotating rod 15 respectively and meshes with each other, the rotation of the first transmission rod 18 will drive the first bevel gear 19 to drive, thereby causing the first rotating rod 15 to rotate around the sealed bearing on the air guide shell 10, providing stable power for the air guide mechanism; When the first rotating rod 15 rotates, it will drive the fan blade 16 fixed on it to rotate synchronously. The fan blade 16 rotates inside the air guide shell 10, forming an airflow guiding force, which allows the air entering the air guide shell 10 through the through hole of the assembly plate 9 to be quickly pushed and flow towards the partition frame 11, reducing the residence time of air in the air guide shell 10 and improving the air circulation efficiency in the purification mechanism.

[0025] In a further preferred embodiment of the present invention, the rotary exhaust mechanism includes: an exhaust pipe 14 rotatably mounted on the exhaust pipe 20 via a sealed bearing, wherein a first ball bearing 41 is embedded in the bottom edge of the exhaust pipe 14 and the first ball bearing 41 contacts an annular groove on the exhaust pipe 20; a first gear 21 fixedly sleeved on the exhaust pipe 14; a second transmission rod 22 rotatably mounted in the housing 1 via a sealed bearing, wherein a second gear 23 meshing with the first gear 21 is fixedly mounted on the second transmission rod 22; and second bevel teeth 24 fixedly fixed on the second transmission rod 22 and the first transmission rod 18 and meshing with each other.

[0026] In this embodiment, during use, the air processed by the purification mechanism enters the exhaust pipe 20. At the same time, the first transmission rod 18 rotates, driving the meshing second bevel gear 24 to drive the transmission. The second bevel gear 24 drives the second transmission rod 22 to rotate around the sealed bearing inside the housing 1. Since the second gear 23 fixed on the second transmission rod 22 meshes with the first gear 21 fixedly sleeved on the exhaust pipe 14, the rotation of the second transmission rod 22 will drive the first gear 21 to rotate, thereby causing the exhaust pipe 14 to rotate around the sealed bearing on the exhaust pipe 20, providing rotational power for the exhaust process. During the rotation of the exhaust pipe 14, the first ball bearing 41 embedded at its bottom edge contacts and rolls with the annular groove on the exhaust pipe 20, reducing the frictional resistance between the exhaust pipe 14 and the exhaust pipe 20, making the rotation of the exhaust pipe 14 smoother; the clean air entering the exhaust pipe 20 is discharged through the rotating exhaust pipe 14. The rotation of the exhaust pipe 14 changes the direction of air discharge, allowing the clean air to diffuse more evenly into the surrounding space, avoiding local air cleanliness differences caused by exhaust in one direction.

[0027] In a further preferred embodiment of the present invention, staggered baffles are fixedly installed inside the partition frame 11 to separate the air passages, the air passages are interconnected, and a plurality of air holes are provided on the air guide shell 10.

[0028] In this embodiment, during use, the air guiding mechanism drives the air flow. The air first contacts the air guiding shell 10. Several air holes on the air guiding shell 10 provide multiple flow inlets for the air, so that the air can enter the interior of the air guiding shell 10 more evenly, avoiding the concentrated congestion of air caused by a single inlet. At the same time, in conjunction with the guiding function of the air guiding shell 10, it prepares the air flow to the partition frame 11. Air guided by the air guide shell 10 enters the partition frame 11. The staggered baffles fixedly installed inside the partition frame 11 divide the internal space into multiple air channels, and the air channels are interconnected. After entering, the air needs to flow along the staggered air channels. During this process, the staggered structure of the air channels prolongs the residence time of the air in the partition frame 11, so that the air can come into more full contact with the filter plate 12 and the germicidal lamp 13 inside the partition frame 11, thereby improving the filtration and sterilization effect. In the entire structure, the air vents of the air guide shell 10 and the staggered air channels of the partition frame 11 work together to optimize the entire airflow path from entry: the air vents ensure the uniformity of air entry and avoid insufficient purification caused by excessive local air; the air channels formed by the staggered baffles enhance the efficiency of the filter plate 12 and the germicidal lamp 13 by extending the airflow path; the combination of the two further improves the overall purification capacity of the purification mechanism, and works with other components of the device to better meet the air quality improvement needs in multiple scenarios and ensure the cleanliness of the exhaust air.

[0029] In a further preferred embodiment of the present invention, a filter bag 3 for filtering impurities is provided inside the filter box 4, a sealing plate is fixed to one side of the filter box 4 by screws, the filter bag 3 is detachably disposed inside the filter box 4, the filter plate 12 is at least one of HEPA filter plate or activated carbon filter plate, and the filter plate 12 is detachably connected to the partition frame 11.

[0030] In this embodiment, during use, the air initially purified by the planting box 5 enters the filter box 4 through the duct 6. The filter bag 3 installed in the filter box 4 filters the impurities remaining in the air, intercepting particulate matter and dust in the air, reducing the total amount of pollutants entering the box 1. At the same time, the filter plate 12, as at least one of HEPA filter plate or activated carbon filter plate, further treats the fine particulate matter or harmful gases when the air flows through the partition frame 11. Through the graded filtration of the filter bag 3 and the filter plate 12, the air cleanliness is gradually improved. After the filter bag 3 has been used for a period of time, the screws on the sealing plate on one side of the filter box 4 can be unscrewed, the sealing plate can be opened, and the filter bag 3 can be taken out from the filter box 4 for replacement or cleaning. After cleaning, the new filter bag 3 can be put into the filter box 4 and the sealing plate can be reinstalled. If the filter plate 12 has a reduced filtration efficiency, since the filter plate 12 and the partition frame 11 are detachably connected, the filter plate 12 can be directly taken out from the partition frame 11 for replacement. The operation is simple and does not require disassembling the entire device. In the entire structure, the filter bag 3 is designed to provide pre-filtration protection before the air enters the housing 1, reducing the filtration burden on the subsequent filter plate 12; different types of filter plates 12 can be selected to adapt to the purification needs of different pollution scenarios, improving the applicability of the device; the detachable design makes the maintenance of filter bag 3 and filter plate 12 more convenient.

[0031] In a further preferred embodiment of the present invention, a shield 31 is fixedly installed on the top of the housing 1 by bolts. The shield 31 has an opening adapted to the air outlet pipe 14. The shield 31 is used to shield and protect the first gear 21 and the second gear 23.

[0032] In this embodiment, when the device is running, the exhaust pipe 14 passes through the opening into the shield shell 31 and rotates to exhaust air. The size of the opening is adapted to the exhaust pipe 14, which not only provides rotation space for the exhaust pipe 14, but also reduces the entry of external dust and impurities into the shield shell 31 through the opening. At the same time, the shield shell 31 encloses the first gear 21 and the second gear 23 inside, preventing the first gear 21 and the second gear 23 from being directly exposed to the outside during meshing transmission, and reducing the interference of external factors on the gear transmission. In the entire structure, the fixed installation of the shield shell 31 provides a stable protective space for the first gear 21 and the second gear 23, preventing gear failure due to collision, dust accumulation or foreign object entrapment, and extending the service life of the gears; the matching design of the inlet and the exhaust pipe 14 ensures the exhaust function while also taking into account the protective effect.

[0033] In a further preferred embodiment of the present invention, at least one layer of mesh plate 7 is provided in the planting box 5, and the filter material carried on the mesh plate 7 is at least one of activated carbon particles, quartz sand or ceramsite, and the green plants planted in the planting cup 8 are herbaceous plants with air purification function.

[0034] In this embodiment, external air first enters the planting box 5 and passes through the branches and leaves of the herbaceous plants in the planting cup 8. The plants adsorb some of the harmful gases and dust in the air through their own physiological processes. Subsequently, the air continues to permeate downwards and passes through the filter material on the mesh plate 7. The filter material further intercepts impurities in the air through physical adsorption. Through the synergistic effect of the plants (such as common air-purifying herbaceous plants such as pothos, spider plants, and ivy, whose leaves adsorb dust and whose root microorganisms degrade harmful gases) and the filter material, the air is initially purified, reducing the total amount of pollutants entering the subsequent filtration stages. In the entire structure, the setting of at least one layer of mesh plate 7 can increase the amount of filter media laid according to the purification needs, thereby improving the adsorption effect. The selection of different types of filter media can adapt to different pollution scenarios and enhance the applicability of the device. Herbaceous plants with air purification function can achieve natural purification and improve the appearance of the device. The combination of green plants and filter media forms a dual preliminary purification.

[0035] In a further preferred embodiment of the present invention, an insect-proof net cover 25 is fixedly installed on the planting box 5 to protect the green plants, and a drain pipe 43 for draining accumulated water is fixedly connected to the bottom of the box body 1, and a valve is provided on the drain pipe 43.

[0036] In this embodiment, the insect-proof net cover 25 prevents external insects such as mosquitoes and moths from entering the planting box 5, avoiding the leaves of the green plants from being eaten or the roots from being damaged, and ensuring the normal growth of the green plants to maintain the air purification capacity; if excess water leaks into the box 1 after watering the planting box 5, or if air condenses and forms water accumulation, the valve on the drain pipe 43 can be opened to allow the water in the box 1 to be discharged through the drain pipe 43, preventing water from stagnating in the box 1 and causing parts to rust or bacteria to grow.

[0037] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments: In another embodiment of the present invention, a cleaning mechanism for cleaning the insect-proof net cover 25 is also provided. The cleaning mechanism includes: a second rotating rod 26 rotatably mounted on the insect-proof net cover 25 via bearings; a cleaning brush 27 fixed on the second rotating rod 26; a third transmission rod 28 rotatably mounted in the shielding shell 31 via bearings; a third bevel tooth 29 respectively fixed on the third transmission rod 28 and the second transmission rod 22 and meshing with each other; a fourth bevel tooth 30 respectively fixed on the third transmission rod 28 and the second rotating rod 26 and meshing with each other; and a protective shell 32 fixed on one side of the shielding shell 31 for shielding the fourth bevel tooth 30.

[0038] In this embodiment, the rotation of the second transmission rod 22 drives the meshing third bevel gear 29 to drive the transmission. Since the third bevel gear 29 is fixed on the second transmission rod 22 and the third transmission rod 28 respectively, the third transmission rod 28 rotates around the bearing in the shielding shell 31. At the same time, the rotation of the third transmission rod 28 drives the meshing fourth bevel gear 30 to drive the transmission. The fourth bevel gear 30 drives the second rotating rod 26 to rotate around the bearing on the insect screen 25, providing power support for the cleaning action and realizing the transmission of power from the existing transmission system to the cleaning mechanism. When the second rotating rod 26 rotates, it will drive the cleaning brush 27 fixed on it to rotate synchronously. The cleaning brush 27 contacts the surface of the insect screen 25 and cleans the dust and impurities attached to the insect screen 25 during the rotation process, so as to prevent impurities from clogging the mesh of the insect screen 25. At the same time, the protective shell 32 fixed on one side of the shielding shell 31 shields the fourth bevel tooth 30 inside, preventing the fourth bevel tooth 30 from being exposed during the transmission process, reducing external dust interference and safety hazards. In the entire cleaning mechanism, the power of the second transmission rod 22 is reused through the cooperation of the third bevel tooth 29, the fourth bevel tooth 30 and the third transmission rod 28, without the need for additional power components, thus simplifying the device structure; the continuous cleaning of the cleaning brush 27 ensures the ventilation of the insect-proof net cover 25, ensuring that the outside air can smoothly enter the planting box 5 and maintain the efficiency of the initial purification stage.

[0039] In another embodiment of the present invention, a sweeping mechanism is also provided, the sweeping mechanism comprising: a guide plate 35 assembled in the air outlet pipe 14 via a first pin 34; a slide rod 39 slidably installed in the air outlet pipe 14; a connecting block 40 fixed on the slide rod 39; a connecting piece 37 movably connected to the guide plate 35 via a second pin 36; one end of the connecting piece 37 away from the guide plate 35 being movably connected to the connecting block 40 via a third pin 38; a sleeve 33 sleeved outside the air outlet pipe 14; the bottom of the sleeve 33 being fixedly connected to a shielding shell 31; the inner wall of the bottom of the sleeve 33 being inclined; the bottom end of the slide rod 39 forming a rolling engagement with the inner annular groove of the sleeve 33 via a second ball bearing 42; and when the air outlet pipe 14 rotates, the second ball bearing 42 rolls along the inner annular groove of the sleeve 33, driving the slide rod 39 to slide axially along the air outlet pipe 14, thereby driving the guide plate 35 to rotate around the first pin 34 to adjust the angle via the connecting block 40 and the connecting piece 37.

[0040] In this embodiment, the air outlet pipe 14 begins to rotate. The bottom of the sleeve 33, which is fitted over the air outlet pipe 14, is fixedly connected to the shielding shell 31 to maintain stability. The rotation of the air outlet pipe 14 causes the second ball bearing 42 at the bottom of the slide rod 39 to roll along the inner annular groove of the sleeve 33. Since the inner wall at the bottom of the sleeve 33 is inclined, the second ball bearing 42 causes the slide rod 39 to slide axially along the air outlet pipe 14 during the rolling process. At the same time, the connecting block 40 fixed on the slide rod 39 moves accordingly, providing a power transmission basis for the angle adjustment of the air guide plate 35, and realizing the power conversion from the rotation of the air outlet pipe 14 to the linear motion of the slide rod 39. When the slide bar 39 slides, the connecting block 40 drives the connecting piece 37 to move through the third pin 38. The end of the connecting piece 37 away from the connecting block 40 is movably connected to the air guide plate 35 through the second pin 36, thereby driving the air guide plate 35 to rotate around the first pin 34 to adjust the angle. The air guide plate 35 rotates in the air outlet pipe 14, changing the flow direction of the purified air discharged through the air outlet pipe 14, so that the purified air can diffuse in different directions and expand the coverage area after air purification.

[0041] A method for using an air purification device, the purification method comprising the following steps: Step 1: Start the motor 17 inside the housing 1. The output shaft of the motor 17 drives the first transmission rod 18 to rotate. On one hand, the first transmission rod 18 drives the first rotating rod 15 to rotate through the meshing first bevel teeth 19, which in turn drives the fan blades 16 inside the air guide shell 10 to rotate, creating a negative pressure around the air guide shell 10 and guiding external air into the purification process. On the other hand, the first transmission rod 18 drives the second transmission rod 22 to rotate through the meshing second bevel teeth 24, providing power for the rotary exhaust mechanism and the cleaning mechanism. Step 2: External air first enters the planting box 5, passes through the insect-proof net cover 25, and comes into contact with the green plants inside the planting cup 8. The green plants absorb some of the pollutants in the air, and then the air is discharged through the air holes on the planting cup 8. Next, it undergoes preliminary filtration through the filter material carried on the mesh plate 7 to remove large particulate impurities from the air. At the same time, the second drive rod 22 drives the third drive rod 28 to rotate through the meshing third bevel teeth 29. The third drive rod 28 drives the second rotating rod 26 to rotate through the meshing fourth bevel teeth 30, thereby causing the cleaning brush 27 to rotate synchronously and clean the dust and impurities attached to the surface of the insect-proof net cover 25 to prevent the mesh from being blocked and affecting the air intake. Step 3: The air, after being initially purified by the planting box 5, enters the filter box 4 through the duct 6. The filter bag 3 inside the filter box 4 further filters out fine impurities, and then enters the box body 1 through the air inlet pipe 2. Step 4: The air entering the chamber 1 enters the air guide shell 10 through the air holes on the air guide shell 10. Under the guidance of the fan blades 16, it flows into the interlaced air channels in the partition frame 11. During the flow of the air in the air channels, the air passes through the filter plate 12 for deep filtration in sequence to remove fine particulate matter such as PM2.5 and PM10. At the same time, the germicidal lamp 13 is activated to sterilize and disinfect the air, completing the deep purification. Step 5: The deeply purified air enters the exhaust pipe 20 at the top of the box 1. At the same time, the second transmission rod 22 drives the exhaust pipe 14 to rotate around the exhaust pipe 20 through the meshing of the second gear 23 and the first gear 21. When the exhaust pipe 14 rotates, the second ball 42 at the bottom of the slide rod 39 inside it rolls along the inner annular groove of the housing 33 (the inner wall of the bottom of the housing 33 is inclined), which drives the slide rod 39 to slide along the axial direction of the exhaust pipe 14. The slide rod 39 drives the air guide plate 35 to rotate around the first pin 34 to adjust the angle through the connecting block 40 and the connecting piece 37. Finally, the purified air is evenly discharged to the external environment through the rotating and adjustable exhaust pipe 14. Step Six: During the purification process, if water accumulates in the chamber 1, the valve on the bottom drain pipe 43 can be opened to drain the water through the drain pipe 43; when the filter bag 3 in the filter box 4 is clogged or malfunctions, the sealing plate on one side of the filter box 4 can be removed and a new filter bag 3 can be replaced; if the cleaning effect of the insect screen 25 decreases, the protective shell 32 can be opened to check the transmission status of the third transmission rod 28 and the fourth bevel tooth 30 to ensure the normal operation of the cleaning mechanism and maintain the purification efficiency of the device.

[0042] In summary, compared with related technologies, the filter material carried by the inner mesh plate 7 of the planting box 5, in conjunction with the purifying green plants in the planting cup 8, achieves preliminary natural purification and physical filtration of the air; the filter bag 3 in the filter box 4 further intercepts impurities, and together with the filter plate 12 in the partition frame 11 and the germicidal lamp 13, a multi-stage purification process is formed, effectively improving air cleanliness; the motor 17, through the first transmission rod 18, the second transmission rod 22 and other transmission components, simultaneously drives the fan blade 16 of the air guiding mechanism to guide the airflow, the exhaust pipe 14 of the rotating exhaust mechanism to uniformly exhaust air, and the cleaning brush 27 of the cleaning mechanism to clean the insect-proof net cover 25, achieving power reuse and a simplified structure; the angle adjustment of the air guide plate 35 of the sweeping mechanism and the rotation of the exhaust pipe 14 are combined to expand the coverage of clean air; the shield shell 31 and the protective shell 32 ensure the stability of the transmission components, and the drain pipe 43 prevents water accumulation.
