[0002] An air purifier is a device that can remove impurities and purify polluted air. It is also called air purification equipment or air cleaning equipment. Its main functions include filtering out or killing pollutants in the air, such as suspended particulate matter, bacteria, viruses, fungal spores, pollen, asbestos, radon decay products, etc., to improve air cleanliness and improve indoor air quality. It is widely used in indoor places, cars and other places. In homes, it can help remove odors, formaldehyde and other harmful gases generated after decoration; in cars, it can effectively remove smoke, odor and other harmful substances in the car to protect the health of drivers and passengers.

[0003] After searching, a Chinese patent with announcement number CN219531106U discloses an air purification device. Since a certain amount of dust is mixed in the indoor air, the dust will be blocked on the outside of the filter component during use. After a period of use, a large amount of dust will adhere to the surface of the outside of the filter component, causing blockage of the filter component, affecting the normal use of the filter component, and greatly reducing the actual service life of the filter component. Therefore, the dust attached to the outer surface of the air filter component can be removed, avoiding the blockage of the air filter component caused by a large amount of dust accumulation, ensuring the normal use of the air filter component, and improving the service life of the air filter component.

[0038] The disassembly and assembly assembly includes a fixing plate 3, which is fixedly connected to the inside of the purification housing 1. An activated carbon filter element 4, a fiber filter element 5 and a fine-pore filter element 6 are arranged below the fixing plate 3. The activated carbon filter element 4 is arranged inside the fiber filter element 5, and the fiber filter element 5 is arranged inside the fine-pore filter element 6, so as to facilitate the gradual purification and filtration of the air.

[0039] One side of the purification housing 1 is rotatably connected to a stud 7, one end of the stud 7 is fixedly connected to a knob 8, and the other side of the purification housing 1 is fixedly connected to a fixing rod 9. The outside of the fixing rod 9 and the stud 7 are both provided with a connecting frame 10, one of the connecting frames 10 and the fixing rod 9 is slidably connected, and the other connecting frame 10 and the stud 7 are threadedly connected. The fixing rod 9 plays a role in limiting the movement of the opening and closing cover 11;

[0040] One end of one of the connecting frames 10 is rotatably connected to the opening and closing cover 11, and the upper surface of the opening and closing cover 11 is provided with an outer ring groove 12, a middle ring groove 13 and an inner ring groove 14. The outer ring groove 12 is arranged outside the middle ring groove 13, and the middle ring groove 13 is arranged outside the inner ring groove 14. One end of the other connecting frame 10 is penetrated by a through rod 15, and the through rod 15 penetrates one side of the opening and closing cover 11. One end of the through rod 15 is provided with a threaded groove 16, and the external thread of the threaded groove 16 is connected to a threaded cover 17. The outer ring groove 12, the middle ring groove 13 and the inner ring groove 14 are convenient for engaging with the bottom of the fine-pore filter element 6, the fiber filter element 5 and the activated carbon filter element 4. The through rod 15 is convenient for fixing the opening and closing cover 11 by using the threaded groove 16 and the threaded cover 17.

[0041] As attached Figure 1 As shown, maintenance components are provided on both sides of the purification housing 1, and the maintenance components include two air intake plates 18. The two air intake plates 18 are provided on both sides of the purification housing 1, and connecting blocks 19 are fixedly connected on both sides of the air intake plates 18. An air outlet 29 is provided on the upper surface of the purification housing 1, and the connecting blocks 19 facilitate the disassembly and assembly of the air intake plates 18.

[0042] As attached Figure 7 As shown, holes 20 are provided on both sides of the connecting block 19 to facilitate engagement with the clamping rod 27 .

[0043] As attached Figure 8 As shown, both sides of the purification shell 1 are fixedly connected with installation boxes 21, two through grooves 22 are provided on both sides of the installation box 21, and two slide grooves 23 are provided on one side of the installation box 21. The installation box 21 facilitates the connection and installation of the connecting block 19, and the slide groove 23 facilitates the sliding of the slider 28.

[0044] As attached Figure 3 As shown, one side of the mounting box 21 is rotatably connected to a bidirectional screw 24, one end of the bidirectional screw 24 is fixedly connected to a knob 25, both ends of the bidirectional screw 24 are threadedly connected to a movable frame 26, and the threads at both ends of the bidirectional screw 24 are set in opposite directions. The movement of the movable frame 26 facilitates the movement of the clamping rod 27.

[0045] As attached Figure 9 As shown, both ends of the mobile frame 26 are fixedly connected with a clamping rod 27, and one side of the mobile frame 26 is fixedly connected with a slider 28. The slider 28 slides inside the slide groove 23 to facilitate limiting the movement of the mobile frame 26.

[0046] Working principle: After the air purification device has been used for a long time, when the internal filter element needs to be taken out, the device is first turned upside down, and then the knob 8 is turned, so that the knob 8 drives the stud 7 to rotate. When the stud 7 rotates, it is convenient to drive the opening and closing cover 11 to move under the limiting action of the fixing rod 9 through the connecting frame 10, so that the opening and closing cover 11 is separated from the purification housing 1, so that the activated carbon filter element 4, the fiber filter element 5 and the fine-pore filter element 6 are respectively separated from the corresponding inner ring groove 14, the middle ring groove 13 and the outer ring groove 12, and then the threaded cover 17 is turned to separate the threaded cover 17 from the threaded groove 16, so as to release the limit of the through-rod 15, and then the through-rod 15 is pulled out of one side of the opening and closing cover 11, so as to release the limit of the opening and closing cover 11, and then the opening and closing cover 11 is rotated to open, and then the filter element inside the purification housing 1 is taken out, so as to facilitate the removal of the filter element. The operation during installation is reversed, and there is no need to use a screwdriver to twist the screws, which is conducive to reducing the difficulty of removing the filter element;

[0047] When the air purification device uses the air intake plate 18 to intake air for a long time, resulting in a lot of dust adhering to the holes of the air intake plate 18 and requiring disassembly and maintenance, the knob 25 is turned so that the knob 25 can drive the bidirectional screw 24 to rotate. When the bidirectional screw 24 rotates, the threads at both ends of the bidirectional screw 24 in opposite directions are used to facilitate the sliding of the slider 28 in the limiting action of the slide groove 23, driving the two movable frames 26 away from each other. At this time, the movable frame 26 will drive the corresponding clamping rod 27 to disengage from the inside of the hole groove 20, so that the connecting block 19 is released from the fixed limit, and then the connecting block 19 is pulled out from the inside of the installation box 21, so that the connecting block 19 can drive the air intake plate 18 to be removed, thereby facilitating the cleaning and maintenance of the air intake plate 18 and reducing the blockage of the air intake holes on the air intake plate 18.

[0048] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
