Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] This utility model provides an air purifier with a pull-out filter cartridge, see reference. Figures 1-8 An air purifier with a pull-out filter cartridge includes an air purifier body 1, a pull-out bracket 4, and a protective mechanism.

[0032] An installation box 2 is fixedly installed on the air purifier body 1. A pull-out bracket 4 is inserted into the installation box 2. A door 3 is rotatably installed on the air purifier body 1. One side of the door 3 is in contact with the pull-out bracket 4. A handle is fixedly connected to one side of the pull-out bracket 4. One side of the handle is in contact with the door 3. The handle not only facilitates the door 3 to block and limit the pull-out bracket 4, but also facilitates the user to disassemble and assemble the pull-out bracket 4. An installation groove is opened on the pull-out bracket 4. A purification filter element 12 is installed in the installation groove. A protective mechanism is provided on the pull-out bracket 4. The protective mechanism is connected to the purification filter element 12. Through the cooperation between the air purifier body 1 and the purification filter element 12, the air purification effect can be achieved. The air purifier body 1 is common in daily life and belongs to the prior art. The specific structure and working principle of the air purifier body 1 can be referred to the document with publication number CN210278541U proposed in this application. It is clear and feasible for those skilled in the art, and will not be described in detail here.

[0033] The protective mechanism includes a rotating shaft 5, a limiting plate 6, a winding roller 7, a dustproof cloth 8, an iron block 9, a magnetic block 10, and a torsion spring 11. Both sides of the pull-out bracket 4 are provided with mounting slots 2, and the rotating shaft 5 is rotatably connected in both mounting slots 2. Through the coordinated design between the air purifier body 1, the mounting box 2, the door 3, the pull-out bracket 4, and the protective mechanism, not only can the purification filter 12 be quickly replaced, but also the dust on one side of the purification filter 12 can be prevented from falling and flying during the replacement of the purification filter 12, thereby avoiding the impact on the surrounding environment and the air purifier body 1.

[0034] In this method, both rotating shafts 5 are fixedly connected to limiting plates 6. One side of each limiting plate 6 is in contact with one side of the purification filter element 12 to limit and fix the purification filter element 12. One side of each limiting plate 6 is equipped with a sealing gasket and is in contact with the purification filter element 12 to improve the sealing performance. Both ends of each rotating shaft 5 are fixedly installed with bearings and are connected to the pull-out bracket 4 to facilitate the rotation of the two rotating shafts 5.

[0035] In this method, one of the two limiting plates 6 has a cavity, and a take-up roller 7 is rotatably connected inside the cavity. A dustproof cloth 8 is fixedly wound on the take-up roller 7. One end of the dustproof cloth 8 passes through the corresponding limiting plate 6 and is fixedly connected to an iron block 9. A storage groove is opened on one side of one of the two limiting plates 6, and the storage groove is adapted to the iron block 9. Through the function of the dustproof cloth 8, when the purification filter element 12 is replaced, it can protect the dust attached to one side, thereby preventing the dust from falling and flying. Both ends of the take-up roller 7 are fixedly fitted with bearings and connected to the corresponding limiting plate 6, which facilitates the take-up roller 7 to wind up and unwind the dustproof cloth 8.

[0036] In this method, one of the two limiting plates 6 has a groove, and a magnetic block 10 is fixedly installed in the groove. The magnetic block 10 corresponds to the iron block 9. The magnetic force of the magnetic block 10 can limit the iron block 9 and make the dustproof cloth 8 taut.

[0037] In this method, torsion springs 11 are fixedly sleeved at both ends of the two rotating shafts 5, and the four torsion springs 11 are fixedly connected to the pull-out bracket 4. Through the elastic potential energy of the four torsion springs 11, the two rotating shafts 5 can be restored to their original state.

[0038] In this method, one end of each of the two rotating shafts 5 passes through the pull-out bracket 4 and is fixedly connected to a rotating plate 1. Each of the two rotating plates 1 is equipped with a limit screw 1, and one end of each limit screw 1 is connected to the pull-out bracket 4 to limit the two rotating shafts 5.

[0039] In this method, one end of the take-up roller 7 passes through the corresponding limiting plate 6 and is fixedly connected to the rotating plate 2. The rotating plate 2 has multiple limiting holes, and a limiting screw 2 is inserted into one of the multiple limiting holes. One end of the limiting screw 2 is threadedly connected to the pull-out bracket 4 to limit the take-up roller 7. The pull-out bracket 4 has a movable groove that is adapted to the take-up roller 7, so that the take-up roller 7 can rotate and move with the corresponding limiting plate 6.

[0040] Working principle: When in use, first open the box door 3 and release the limit screw two from the limit plate two, thereby releasing the limit on the take-up roller 7. At this time, the weight of the iron block 9 pulls the dust cloth 8 downward. At the same time, with the cooperation of the dust cloth, the take-up roller 7 rotates on the pull-out frame 4 and releases the dust cloth 8. (When the iron block 9 cannot smoothly pull the dust cloth 8 downward, the turn plate two can be manually rotated and the take-up roller 7 can be used to assist in releasing the dust cloth 8.) After that, when the dust cloth 8 is released, the iron block 9 is connected to the magnetic block 10, and the dust cloth 8 is taut under the action of the magnetic force.

[0041] At this time, through the cooperation between the dustproof cloth 8, the pull-out bracket 4 and the two limiting plates 6, the dust filtered by the purification filter 12 can be prevented from falling and spreading during the disassembly of the pull-out bracket 4, and the dust can be prevented from falling into the air purifier body 1.

[0042] Next, by pulling the handle on one side of the pull-out bracket 4, the pull-out bracket 4 is pulled out of the mounting box 2, thereby achieving the purpose of disassembling the pull-out bracket 4. Then, the pull-out bracket 4 is placed horizontally with the dustproof cloth 8 facing upwards. By rotating the winding roller 7 in the reverse direction, the iron block 9 is disengaged from the magnetic block 10, and the dustproof cloth 8 is wound up, thereby achieving the purpose of storing the dustproof cloth 8 and the iron block 9. Then, by sequentially releasing the two limiting screws on the two rotating plates and the two rotating shafts 5, during this process, when the limiting screws are released from the pull-out bracket 4, the elastic potential energy of the torsion springs 11 at both ends of the corresponding rotating shafts 5 causes the rotating shafts 5 to drive the limiting plates 6 to rotate 90°, thereby causing both limiting plates 6 to disengage from the purification filter element 12. Then, the purification filter element 12 is removed from the mounting slot on the pull-out bracket 4 (refer to the attached document). Figure 5 );

[0043] Next, the new purification filter element 12 is installed in the installation slot one. Then, by rotating the two rotating shafts 5 in reverse order, the four torsion springs 11 are charged and one side of the two limiting plates 6 is brought into contact with one side of the replaced purification filter element 12. The two limiting screws one and two limiting screws two are connected to the pull-out bracket 4 in sequence. At this time, through the interaction between the two limiting screws one and two and the pull-out bracket 4 and the cooperation of the two rotating plates one and two, the two rotating shafts 5 and the winding roller 7 can be limited and fixed.

[0044] Next, insert the pull-out bracket 4 into the mounting box 2, close the box door 3, and make one side of the box door 3 contact the handle on the pull-out bracket 4, thereby achieving the purpose of installing the pull-out bracket 4.

[0045] In summary, this allows for the rapid replacement of the purification filter element 12.

[0046] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, not only can the purification filter element 12 be quickly replaced, improving convenience and efficiency, but also the dust on one side of the purification filter element 12 can be prevented from falling and flying during the replacement process, thereby avoiding the impact on the surrounding environment and the main body of the air purifier 1, further enhancing convenience. Moreover, the structure is simple and more practical.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
