Description

Technical Field

[0001] The present invention relates to the technical field of air purification, and in particular to an air purification and deodorization device. Background Art

[0002] Air purification and deodorization devices commonly found on the market are primarily used in indoor environments, and are widely used to improve air quality, particularly in homes, offices, and public places. These devices typically use filtration technology to remove harmful substances from the air, such as dust, particulate matter, bacteria, viruses, and harmful gases.

[0003] Some existing air purification and deodorization equipment utilize single- or double-sided air inlet designs. Due to the fixed airflow direction, the front working surface of the filter cartridge, facing the air inlet, gradually becomes saturated, accumulating large amounts of airborne particulate matter, microorganisms, and other impurities, while the rear area, facing away from the air inlet, remains relatively clean. These pollutants are unevenly distributed across the filter cartridge surface, resulting in significant variations in the degree of wear across different parts of the filter cartridge, thus affecting the equipment's purification efficiency.

[0004] Secondly, during actual use, the surface of the air inlet filter plate of the equipment housing easily accumulates a lot of dust and dirt. However, the air inlet filter plates of existing equipment are mostly fixed in design, which is not convenient for disassembly and maintenance, causing many inconveniences during daily cleaning.

[0005] Furthermore, existing air purification and deodorization equipment typically utilizes integrated multi-layer filter cartridges. When a portion of the filter layer reaches the end of its service life due to accumulation of dirt, users must replace the entire filter cartridge. However, often only a portion of the filter layer in a multi-layer filter cartridge actually fails, while the remaining layers remain usable. This complete replacement method increases maintenance costs for users. Summary of the Invention

DETAILED DESCRIPTION

[0023] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0024] See also Figure 1-18The present invention provides an air purification and deodorization device, comprising a lower shell 1 and a filter cartridge 3. The front and right sides of the lower shell 1 are detachably connected to an air inlet filter plate 2. The interior of the lower shell 1 is detachably connected to a fixing frame 4. The inner side of the fixing frame 4 is connected to a rotating assembly 5 for driving the filter cartridge 3 to rotate. The lower end of the fixing frame 4 is connected to a limiting assembly 6 for limiting the rotation of the filter cartridge 3. The lower end opening of the lower shell 1 is fixedly connected to a fixing frame 7. The inner side of the fixing frame 7 is detachably connected to a bottom cover plate 71. The upper end of the lower shell 1 is fixedly connected to an upper shell 8. A fan assembly 81 is fixedly installed inside the upper shell 8. The fixing frame 4 includes an upper fixing plate 41 and a lower fixing plate 42, and the upper fixing plate 41 and the lower fixing plate 42 are connected by a side telescopic frame 43, and the side telescopic frame 43 is detachably connected to the inside of the lower shell 1. The rotating assembly 5 includes an upper turntable 51 and a lower turntable 52. The upper turntable 51 is rotatably connected to the lower surface of the upper fixing plate 41. The surfaces of the upper fixing plate 41 and the upper turntable 51 are respectively provided with a second air outlet 411 and a third air outlet 514. The lower turntable 52 is rotatably connected to the upper surface of the lower fixing plate 42. The filter cartridge 3 is clamped between the upper turntable 51 and the lower turntable 52. The lower end of the lower turntable 52 is fixedly connected to the rotating cylinder 53. A rotating hole 421 is opened through the center position of the surface of the lower fixing plate 42, and the rotating cylinder 53 rotates through this hole. The filter cartridge 3 is composed of an outer layer cartridge 31, a middle layer cartridge 32 and an inner layer cartridge 33 from the outside to the inside. Each layer is independent of each other, and a buffer spacing of 5-10 mm can be retained between each layer to balance wind resistance and filtration efficiency. The upper and lower ends of the outer layer cartridge 31, the middle layer cartridge 32 and the inner layer cartridge 33 are detachably connected to the upper turntable 51 and the lower turntable 52 respectively.

[0025] Specifically, the filter cartridge 3 is clamped between the upper turntable 51 and the lower turntable 52. By rotating the rotating cylinder 53, the manual axial rotation adjustment of the filter cartridge 3 can be indirectly achieved, so that the user can adjust the orientation of the working surface of the filter cartridge 3 according to the actual use situation, thereby optimizing the filtering effect. Specifically, after the equipment has been used for a period of time, the front working surface of the filter cartridge 3 facing the air inlet 11 will gradually become saturated, accumulating a large amount of particulate pollutants, microorganisms and other impurities in the air, while the rear area facing away from the air inlet 11 remains relatively clean. At this time, the user can rotate the filter cartridge 3 by rotating the rotating cylinder 53, so that the originally saturated working surface is turned to the inside of the lower shell 1, and at the same time adjust the clean working surface to the position of the air inlet 11, thereby restoring and maintaining an efficient filtering effect. After the adjustment is completed, the position of the filter cartridge 3 after rotation adjustment can be firmly locked by the limit assembly 6 to prevent it from shifting during operation.

[0026] By providing the fixing frame 4, the upper fixing plate 41 and the lower fixing plate 42 are connected by the side telescopic frame 43, which not only ensures a secure clamping of the filter cartridge 3, but also simplifies the assembly and disassembly process of the filter cartridge 3, making it more efficient and convenient. When the filter cartridge 3 needs to be removed, the overall length of the side telescopic frame 43 is simply adjusted to increase the distance between the upper fixing plate 41 and the lower fixing plate 42, and the filter cartridge 3 can be easily removed.

[0027] Each of the three filter cartridges can be independently removed and installed. After a period of operation, the user can selectively replace or clean the three filter cartridges according to their different usage conditions. For example, if the mesh surface of the outer cartridge 31 is heavily contaminated, the user can simply remove it for cleaning without having to replace the entire unit, significantly reducing maintenance costs.

[0028] Specifically, when the device is in operation, the fan assembly 81 in the upper housing 8 begins to operate, forming a stable negative pressure airflow. During this process, external air will first enter the lower housing 1 through the air inlet filter plate 2 (the air inlet filter plate 2 acts as a primary filter, intercepting larger particles of dirt or impurities). Then, the air filtered by the air inlet filter plate 2 will pass through the filter cartridge 3 and enter the interior of the filter cartridge 3. During the filtration process of the filter cartridge 3, dust, impurities, odors, bacteria, and other harmful substances in the air will be adsorbed and blocked by the filter material of the filter cartridge 3, achieving the effect of air purification and deodorization. Subsequently, the air that has completed the purification process is released into the indoor environment under the continuous suction action of the fan assembly 81.

[0029] It should be noted that the fan assembly 81 and the control circuit structure installed inside the upper shell 8 adopt conventional technical means in this field, and their specific structures will not be described in detail herein.

[0030] Furthermore, the front side wall and the right side wall of the lower shell 1 are penetrated by the air inlet 11, and the middle position of both sides of the air inlet 11 is provided with a square groove 111, and the upper and lower ends of the square groove 111 are provided with a fixing hole 112. The air inlet filter plate 2 is symmetrically fixed with longitudinal rods 21 on both sides. The interior of each group of longitudinal rods 21 is longitudinally penetrated by a through hole 211, and the upper and lower ends of the side walls of the longitudinal rods 21 are provided with a movable groove 212 connected to the through hole 211. The interior of the through hole 211 is symmetrically slidably provided with a fixing rod 22. The two groups of fixing rods 22 are fixedly connected by a spring 1 23. The two groups of fixing rods 22 are elastically abutted against the fixing hole 112 on the corresponding side under the elastic action of the spring 1 23. The side walls of the opposite ends of the two groups of fixing rods 22 are fixedly connected with a movable block 221, which is slidably connected to the movable groove 212 on the corresponding side, and the side of the movable block 221 away from the fixing rod 22 is fixedly connected with a shift block 222.

[0031] Specifically, after the equipment has been running for a period of time, the air inlet filter plate 2 is easily contaminated with dust and needs to be removed and cleaned regularly. The specific disassembly process is to simultaneously manipulate the two sets of shifting blocks 222 located on the same side of the longitudinal rod 21 to bring them closer together. The two sets of shifting blocks 222 respectively drive the fixed rod 22 closer together through the movable block 221, causing the fixed rod 22 to gradually disengage from the fixing hole 112 and retract into the through hole 211. At this time, the spring 1 23 is in a compressed state, thus completing the disassembly of one side of the air inlet filter plate 2. Next, manipulate the two sets of shifting blocks 222 on the other side to move closer together, thereby completing the disassembly of the other side of the air inlet filter plate 2. After cleaning the air inlet filter plate 2, reinstall it at the air inlet 11. The specific installation process is to first retract the two sets of fixed rods 22 into the through hole 211 using the two sets of shifting blocks 222, and then place the longitudinal rod 21 into the square groove 111. After being placed in place, the two sets of shift blocks 222 are released, and the spring 1 23 recovers its deformation, thereby elastically squeezing the two sets of fixing rods 22 into the fixing holes 112 on the corresponding side, thus completing the installation of the air inlet filter plate 2. The disassembly and assembly process is simple and convenient, and the air inlet filter plate 2 can be quickly disassembled and assembled, greatly improving the efficiency of cleaning and maintenance.

[0032] In addition, the front side wall and the right side wall of the lower shell 1 are penetrated by an air inlet 11, and the rear side wall and the left side wall are designed as a back panel, which is convenient for users to move the device to a wall or a corner for use.

[0033] Furthermore, the outer cylinder 31 is a pre-filtration layer, the middle cylinder 32 is a purification layer, and the inner cylinder 33 is a deodorization layer. The interior of the inner cylinder 33 is connected to the air outlet 3 514. The upper end openings of the outer cylinder 31, the middle cylinder 32 and the inner cylinder 33 are fixedly connected with the upper fixed ring seat 34, and the lower end openings of the outer cylinder 31, the middle cylinder 32 and the inner cylinder 33 are fixedly connected with the lower fixed ring seat 35. The lower surface of the upper turntable 51 is provided with three groups of concentric and annular upper mounting grooves 511. The three groups of upper fixed ring seats 34 are movably inserted into the three groups of upper mounting grooves 511 respectively, and three groups of concentric and annular lower mounting grooves 521 are opened on the upper surface of the lower turntable 52. The three groups of lower fixed ring seats 35 are movably inserted into the three groups of lower mounting grooves 521 respectively. The upper surface of the upper fixed ring seat 34 is bonded with a main annular magnet piece 342, and the inner side of the upper mounting groove 511 is bonded with a secondary annular magnet piece 513 that magnetically matches the main annular magnet piece 342. The lower surface of the lower fixed ring seat 35 is bonded with an annular sealing gasket 351.

[0034] Specifically, the outer cylinder 31 can be made of a high-density nylon mesh to trap larger airborne particles like PM10, such as dust and pollen. The middle cylinder 32 can utilize a pleated HEPA filter. This structure increases the surface area of ​​the filter material, significantly improving filtration efficiency. It is primarily used to filter out tiny particles like PM2.5 and bacteria. The inner cylinder 33 can be filled with activated carbon granules to absorb gaseous pollutants like formaldehyde and odors, further purifying and deodorizing the air and improving indoor air quality.

[0035] In addition, the upper ends of the three groups of filter cartridges are magnetically attracted to the upper mounting groove 511 via the upper fixed ring seat 34. When disassembly is required, it can be removed by applying appropriate external force, which is convenient and quick, reducing the operational complexity during the disassembly process. An annular sealing gasket 351 is provided between the lower fixed ring seat 35 and the lower mounting groove 521 at the lower end of each of the three groups of filter cartridges, which can effectively enhance their sealing. The side walls of the upper mounting groove 511 and the lower mounting groove 521 are each provided with a slot 512. The side walls of the upper fixed ring seat 34 and the lower fixed ring seat 35 are fixedly connected to the side walls of the upper fixed ring seat 34 and the lower fixed ring seat 35, which are plugged into the slot 512. After the three groups of filter cartridges are installed in place, the pin 341 is synchronously inserted into the slot 512 at the corresponding position. At this time, the upper fixed ring seat 34 and the upper turntable 51, and the lower fixed ring seat 35 and the lower turntable 52 can only rotate synchronously.

[0036] Furthermore, the side telescopic frame 43 includes a main fixing rod 431 and a secondary fixing rod 432. The upper end of the main fixing rod 431 is fixedly connected to the rear side of the upper fixing plate 41, and the lower end of the secondary fixing rod 432 is fixedly connected to the rear side of the lower fixing plate 42. The secondary fixing rod 432 is slidably connected to the inner lower end of the main fixing rod 431, and the main fixing rod 431 and the secondary fixing rod 432 are fixed by two groups of elastic limiters 433 and two groups of fixing bolts 434. Threaded holes 4312 are opened on both sides of the upper end of the main fixing rod 431, and locking holes 4322 are opened on both sides of the lower end of the secondary fixing rod 432. The end thread of the fixing bolt 434 passes through the threaded hole 4312 and extends to abut against the inside of the locking hole 4322.

[0037] Specifically, when the filter cartridge 3 needs to be removed, only the overall length of the side telescopic frame 43 needs to be adjusted. First, the fixing bolt 434 is unscrewed so that the end of the fixing bolt 434 disengages the locking hole 4322. At this time, the fixed position between the main fixing rod 431 and the secondary fixing rod 432 is lost. Next, the secondary fixing rod 432 is pulled downward. Under the action of the pulling force, the elastic limiter 433 loses its elastic limit, thereby increasing the overall length of the side telescopic frame 43. Conversely, when the filter cartridge 3 needs to be installed, the secondary fixing rod 432 is pushed toward the main fixing rod 431 until the elastic limiter 433 elastically limits the secondary fixing rod 432. At this time, the threaded hole 4312 and the locking hole 4322 are aligned. The user can directly use the fixing bolt 434 to fix the two, thereby reducing the time cost required for positioning and installation, making installation more efficient and convenient.

[0038] Furthermore, movable holes 4311 are provided on both sides of the lower end of the main fixing rod 431, and limiting holes 4321 are provided on both sides of the left and right sides of the secondary fixing rod 432. The elastic limiting part 433 includes a sleeve seat 4331, a limiting pin 4332 and a cylinder cover 4334. The sleeve seat 4331 is located on the outside of the movable hole 4311 on the corresponding side and is fixedly connected to the main fixing rod 431. The limiting pin 4332 is slidably connected to the inside of the movable hole 4311 on the corresponding side. A spring 2 4333 is installed inside the sleeve seat 4331, and the cylinder cover 4334 is threadedly connected to the outside of the sleeve seat 4331. One end of the spring 2 4333 abuts against the limiting pin 4332, and the other end of the spring 2 4333 abuts against the inner top wall of the cylinder cover 4334.

[0039] Specifically, when the secondary fixing rod 432 is pulled downward, the stop pin 4332 gradually disengages from the stop hole 4321 and is completely squeezed into the movable hole 4311, compressing the second spring 4333. Furthermore, the sleeve cover 4334 is threadedly connected to the sleeve seat 4331, facilitating easy replacement and maintenance of the stop pin 4332 and the second spring 4333.

[0040] Furthermore, the upper end opening of the lower shell 1 is fixedly connected to the top plate 13, and the center position of the top plate 13 is penetrated by an air outlet 131, and the lower surface of the top plate 13 is fixedly connected to the outside of the air outlet 131 with a ring seat 132, and the lower surface of the ring seat 132 is provided with an annular groove 1321, and the upper surface of the upper fixed plate 41 is fixedly connected to the outside of the air outlet 2 411 with an annular seat 412, and the annular seat 412 is movably inserted into the annular groove 1321, and the lower end of the lower fixed plate 42 is connected to the protective cylinder 422 by bolts, and the lower surface of the protective cylinder 422 is fitted to the upper surface of the bottom cover 71, and the lower end of the rotating cylinder 53 sequentially passes through the protective cylinder 422 and the bottom cover 71, and the inner rear side wall of the lower shell 1 is fixedly connected to the longitudinal slide rail 12, and the rear side of the main fixing rod 431 is fixedly connected to the slide bar 44, and the slide bar 44 is slidably connected to the inside of the slide rail 12.

[0041] Specifically, the fixing bracket 4 is sandwiched between the top plate 13 and the bottom cover 71. When the filter cartridge 3 needs to be replaced or cleaned, the bottom cover 71 is simply removed. The lower end of the fixing bracket 4 is now free of its retaining position, allowing the fixing bracket 4 to be lowered and removed from the lower housing 1. During removal, the main fixing rod 431 drives the slide bar 44 to slide within the slide rail 12. The slide rail 12 guides and limits the slide bar 44, ensuring that the fixing bracket 4 can be smoothly installed in the predetermined position in the lower housing 1. Next, when the fixing bracket 4 needs to be installed, the slide bar 44 is simply aligned with the slide rail 12 and inserted, and the fixing bracket 4 is pushed toward the top plate 13 until the annular seat 412 is inserted into the annular groove 1321. A sealing gasket can be added to the annular groove 1321 to enhance the seal, thereby ensuring that the filtered and purified air within the filter cartridge 3 can flow smoothly through the air outlet 3 514, the air outlet 2 411, and the air outlet 1 131, in that order, to the fan assembly 81.

[0042] Furthermore, the limiting assembly 6 includes an outer gear ring 61 and a fixed plate 62. The outer gear ring 61 is fixedly sleeved on the outer side of the rotating cylinder 53. The fixed plate 62 is fixedly connected to the lower surface of the lower fixed disk 42. A movable plate 63 is slidably provided on the lower surface of the fixed plate 62. A fixed seat 64 is fixedly connected to the left side of the lower surface of the fixed plate 62. The movable plate 63 is located on the right side of the fixed seat 64 and two sets of elastic telescopic rods 65 are sandwiched between the two. The elastic telescopic rod 65 includes an upper cylinder, a lower cylinder and a spring. The upper cylinder is slidably provided on the inner upper end of the lower cylinder. The spring is fixedly connected between the upper cylinder and the lower cylinder. The right side of the movable plate 63 is fixedly connected with a limit tooth 66. The limit tooth 66 elastically abuts against the tooth groove of the outer gear ring 61. The center position of the lower surface of the fixed plate 62 is rotatably connected with an operating rod 68. The upper end of the operating rod 68 is fixedly sleeved on the outside with a limit seat 69 for limiting the sliding of the movable plate 63. The limit seat 69 is designed in the shape of a rectangular parallelepiped, and both sides of the rectangular parallelepiped are set as semicircular arc edges. The lower end of the operating rod 68 passes through the protective tube 422 and the bottom cover plate 71 in sequence.

[0043] Specifically, when it is necessary to restrict the movement of the movable plate 63, the operating lever 68 is simply rotated 90 degrees to adjust the long side of the limit seat 69 to a 90-degree angle with the movable plate 63. At this time, the movable plate 63 is fixed under the action of the limit seat 69 and cannot slide laterally. At this time, the limit teeth 66 are firmly stuck in the tooth grooves of the outer gear ring 61, preventing the outer gear ring 61 from further rotation. When it is necessary to release the limit of the movable plate 63, the operating lever 68 is rotated 90 degrees in the opposite direction to adjust the long side of the limit seat 69 to a parallel state with the movable plate 63, and the movable plate 63 is restored to its movable state.

[0044] During actual operation, when the rotating drum 53 indirectly drives the filter drum 3 to rotate, it also drives the outer gear ring 61 to rotate synchronously. As the outer gear ring 61 rotates, the limiting teeth 66 drive the movable plate 63 to move back and forth along the lower surface of the fixed plate 62. At this time, the elastic telescopic rod 65 will expand and contract as the movable plate 63 slides, ensuring sufficient elastic support for the movable plate 63 during its sliding process. After the filter drum 3 is adjusted, the operating lever 68 is manually rotated, which drives the limiting seat 69 to rotate 90 degrees. The movable plate 63 is now limited by the limiting seat 69 and cannot slide, causing the limiting teeth 66 to be stuck in the tooth grooves of the outer gear ring 61.

[0045] The cam 684 is fixedly connected to the outside of the main rod 681 and the cam 685 is fixedly connected to the outside of the main rod 681. Among them, spring three 683 keeps the slider 684 at the lower end position of slide groove one 6711 or slide groove two 6712 in a natural state. When the slider 684 slides to the upper end along slide groove one 6711, it can move along the arc-shaped slide groove 6713 to slide groove two 6712, and slide downward to the lower end of slide groove two 6712 under the action of spring three 683 to realize rotation locking.

[0046] Specifically, when the operating lever 68 needs to rotate the limit seat 69, the first step is to press upward on the rotating head 685. The rotating head 685 drives the main rod 681 to slide upward relative to the auxiliary rod 682. At this time, the main rod 681 drives the slider 684 to slide upward along the first slide 6711 and compress the third spring 683. When the slider 684 moves to the top of the first slide 6711, the rotating head 685 is rotated, which indirectly drives the slider 684 to continue sliding along the arc-shaped slide 6713 until it slides to the upper end of the second slide 6712. Then, the rotating head 685 is released, and the third spring 683 recovers its deformation, pressing the main rod 681 downward to reset it. The main rod 681 drives the slider 684 to slide from the upper end to the lower end of the second slide 6712, thus achieving the rotation lock of the operating lever 68.

[0047] Furthermore, threaded adjustment holes 70 are provided at the four corners of the lower surface of the fixing frame 7. The two sets of threaded adjustment holes 70 on the rear side are detachably connected to the inside of moving wheels 72, and the two sets of threaded adjustment holes 70 on the front side are detachably connected to the inside of feet 73.

[0048] Specifically, the moving wheel 72 can be a universal wheel, and a long threaded rod is fixedly connected to the upper end of its wheel frame or the upper end of the anchor base. The long threaded rod is threadedly installed inside the threaded adjustment hole 70. By adjusting the length of the long threaded rod in the threaded adjustment hole 70, the actual height of the moving wheel 72 and the anchor 73 can be changed to adapt to different usage environments and needs.

[0049] Furthermore, the upper end opening of the upper shell 8 is detachably connected to the upper cover plate 9, and the center of the upper cover plate 9 is penetrated by an air outlet 91. The interior of the air outlet 91 is detachably connected to an air outlet filter plate 92. The upper end of the upper cover plate 9 is detachably connected to a deflector 10 for changing the wind direction. The upper end of the upper cover plate 9 and the outer side of the air outlet 91 are fixedly connected with a fixing ring 93. The deflector 10 includes a connecting ring 101 and a cover shell 102. The connecting ring 101 is threadedly sleeved on the inner side of the fixing ring 93, and the cover shell 102 is rotatably sleeved on the outer side of the connecting ring 101. At the upper side end, a side air outlet 1021 is opened through one side of the cover shell 102, and the inner top wall of the cover shell 102 is fixedly connected with a U-shaped seat 103. The opening of the U-shaped seat 103 is consistent with the direction of the side air outlet 1021. The interior of the U-shaped seat 103 is detachably connected with a fragrance box 104. Guide grooves are opened on the inner sides of both side edges of the U-shaped seat 103. The left and right sides of the fragrance box 104 are fixedly connected with guide strips that cooperate with the guide grooves. A magnet sheet is bonded to the inner side of the horizontal edge of the U-shaped seat 103, and the back side of the fragrance box 104 is made of iron material.

[0050] Specifically, the provision of the air deflector 10 allows the user to adjust the air flow direction of the air outlet 91 as needed. Furthermore, the air deflector 10 effectively shields the area directly above the air filter disc 92, forming a physical barrier that prevents external debris from passing through the air filter disc 92 and falling back into the fan assembly 81 within the upper housing 8, thereby extending the service life of the device.

[0051] Specifically, when the wind direction needs to be changed, the cover shell 102 can be installed by simply threading the connecting ring 101 with the fixing ring 93. Then, by rotating the cover shell 102, the direction of its side air outlet 1021 can be changed, thereby achieving the purpose of changing the wind direction. Secondly, a U-shaped seat 103 for fixing the fragrance box 104 is also installed on the inner top wall of the cover shell 102. The user can choose whether to install the fragrance box 104 according to actual needs. When installing the fragrance box 104, it is only necessary to align the guide strips on both sides of the fragrance box 104 with the guide grooves and insert them. After the fragrance box 104 is inserted into place, the magnet sheet will firmly magnetically attract the fragrance box 104 to the inside of the U-shaped seat 103. A fragrance sheet can be placed inside the fragrance box 104, and the fragrance is carried by the continuously blown air and then flows out through the side air outlet 1021, thereby creating a fresh air environment indoors and enhancing the user's experience and comfort.

[0052] Working principle: During operation, the fan assembly 81 within the upper housing 8 begins to operate, creating a stable negative pressure airflow. During this process, external air enters the lower housing 1 through the inlet filter plate 2. The filtered air then passes through the outer cylinder 31, the middle cylinder 32, and the inner cylinder 33, undergoing three layers of filtration, purification, and deodorization before entering the interior of the filter cylinder 3. Finally, under the continuous suction of the fan assembly 81, the purified and deodorized air is released into the indoor environment through the outlet filter disc 92 at outlet 3 514, outlet 2 411, outlet 1 131, and outlet 4 91.

[0053] After the equipment has been running for a period of time, the working surface of the filter cartridge 3 facing the air inlet 11 will gradually become saturated, accumulating a large amount of particulate pollutants, microorganisms and other impurities in the air. At this time, the user can first use the joystick 68 to release the limit of the movable plate 63, so that the movable plate 63 and the limiting teeth 66 can slide horizontally. Then rotate the rotating cylinder 53. The rotating cylinder 53 drives the filter cartridge 3 and the upper turntable 51 to rotate synchronously through the lower turntable 52, so that the originally saturated working surface is turned to the inside of the lower shell 1, and at the same time, the clean working surface is adjusted to the position of the air inlet 11, thereby restoring and maintaining an efficient filtering effect. After the adjustment is completed, the user indirectly limits the movable plate 63 again through the joystick 68. The limiting teeth 66 after limiting are firmly abutted in the tooth groove of the outer gear ring 61. At this time, the outer gear ring 61 and the rotating cylinder 53 will not be able to rotate, thereby firmly locking the position of the filter cartridge 3 after rotation adjustment.

[0054] When the filter cartridge 3 needs to be disassembled and cleaned, the bottom cover 71 is first removed. At this time, the position restriction of the fixing frame 4 is no longer restricted, and the fixing frame 4 can be downwardly removed from the lower housing 1. Next, the overall length of the side telescopic frame 43 is adjusted so that the secondary fixing rod 432 gradually separates from the main fixing rod 431. During the separation process, the lower fixing ring seat 35 at the lower end of the outer tube 31, middle tube 32, and inner tube 33 will separate from the lower turntable 52. Then, the upper fixing ring seat 34 at the upper end of the outer tube 31, middle tube 32, and inner tube 33 can be manually removed from the upper turntable 51, and the filter cartridge 3 can be cleaned.

[0055] In order to ensure long-term efficient and stable operation of the equipment, users also need to regularly remove the air inlet filter plate 2 of the air inlet 11 and the air outlet filter plate 92 of the air outlet 91 for cleaning.

[0056] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
