Description

Technical Field

[0001] This utility model relates to the field of air purifier technology, specifically to an air purifier filter with a quick-release structure. Background Technology

[0002] With increasing attention being paid to air quality issues, air purifiers have become an indispensable purification device in homes, offices, and other places. As the core filtration component of air purifiers, the filtration effect of the filter directly determines the purification efficiency of the purifier.

[0003] However, the filters in existing air purifiers need to be replaced or cleaned regularly. There are some shortcomings in the design of the disassembly and assembly structure. Traditional filters are mostly installed in the purifier by screws, clips, or direct plugging and unplugging. The disassembly and assembly process often requires special tools such as screwdrivers, which is cumbersome, time-consuming and laborious. When disassembling, the filter is often tightly attached to the inner wall of the installation cavity after long-term use, or the clips are too tight, making it difficult to manually grasp or unlock. It requires force to pry it off, which not only increases the difficulty of operation, but also easily causes filter deformation, clip breakage and other damage, reducing the service life of the filter and the purifier. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an air purifier filter with a quick-release structure, which solves the problem of cumbersome disassembly of existing air purifier filters.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An air purifier filter with a quick-release structure includes: a purifier, wherein a grille is fixedly connected to the inner wall of the purifier by screws, and a filter element holder is slidably connected to the inner wall of the purifier; an installation cavity is formed in the inner wall of the purifier, and slots are symmetrically formed on the inner wall of the side of the installation cavity; guide blocks are symmetrically fixedly connected to the inner wall of the installation cavity, and sliding cavities are symmetrically formed on the inner wall of the guide blocks; a top plate is slidably connected to the inner wall of the sliding cavity; a pressure spring is fixedly connected to the outer wall of the top plate, and a top rod is fixedly connected to the outer wall of the top plate on the side away from the pressure spring.

[0006] Preferably, the outer wall of the push rod is slidably connected to the inner wall of the guide block, and the outer wall of the pressure spring on the side away from the top plate is fixedly connected to the inner wall of the slide cavity. When the push rod is squeezed, it retracts into the slide cavity after being pressed, pushing the top plate to compress the pressure spring. At this time, the pressure spring stores elastic potential energy to prepare for subsequent disassembly and opening.

[0007] Preferably, a filter screen is fixedly connected to the inner wall of the filter element frame, guide grooves are symmetrically opened on the outer wall of the filter element frame, sliding grooves are symmetrically opened on the outer wall of the side of the filter element frame, sliding rods are symmetrically fixedly connected to the inner wall of the sliding grooves, a pressing plate is slidably connected to the outer wall of the sliding rod, a locking block is fixedly connected to the outer wall of the pressing plate, and compression springs are symmetrically fixedly connected to the outer wall of the pressing plate on the side away from the locking block.

[0008] Preferably, the outer wall of the compression spring pressing plate is fixedly connected to the inner wall of the slide groove, the outer wall of the filter element frame is slidably connected to the inner wall of the mounting cavity, the inner wall of the guide groove is slidably connected to the outer wall of the guide block, the inner wall of the guide groove is in contact with the outer wall of the top rod, the guide groove of the outer wall of the filter element frame is aligned with the guide block of the inner wall of the mounting cavity, the filter element frame is manually pushed into the mounting cavity along the guide block, the outer wall of the locking block is slidably engaged with the inner wall of the locking groove, when the filter element frame is pushed into the preset depth, the locking block and the locking groove are precisely aligned, at this time the compression spring compressed by the pressing plate releases elastic potential energy, pushes the pressing plate to slide along the slide rod towards the locking groove, and finally drives the locking block to insert into the locking groove and form a sliding engagement.

[0009] This invention provides an air purifier filter with a quick-release structure. It has the following advantages: (I) This filter cartridge holder, through the cooperation of "guide blocks and guide grooves", the elastic snap-fit ​​of "compression springs and locking blocks and slots", and the spring-opening assistance of "pressure springs and push rods", completely eliminates the dependence of traditional filters on tools. During installation, simply align the guide structure and push it in, and the locking blocks will automatically snap into place. The entire operation does not require screw removal and is quick. During disassembly, simply press the press plate with both hands to unlock the locking mechanism, and the pressure spring will automatically spring open the filter cartridge holder, preventing the filter from being too tightly fitted to the installation cavity and difficult to grasp.

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.

[0013] Please see Figures 1-6 This utility model provides a technical solution: an air purifier filter with a quick-release structure, comprising: a purifier 1, a grille plate 2 fixedly connected to the inner wall of the purifier 1 by screws, a filter element holder 3 slidably connected to the inner wall of the purifier 1; an installation cavity 11 is opened in the inner wall of the purifier 1, and slots 12 are symmetrically opened on the inner wall of the side of the installation cavity 11; guide blocks 13 are symmetrically fixedly connected to the inner wall of the installation cavity 11; sliding cavities 14 are symmetrically opened on the inner wall of the guide blocks 13; a top plate 15 is slidably connected to the inner wall of the sliding cavity 14; a pressure spring 16 is fixedly connected to the outer wall of the top plate 15; and a top rod 17 is fixedly connected to the outer wall of the top plate 15 on the side away from the pressure spring 16.

[0014] The outer wall of the push rod 17 is slidably connected to the inner wall of the guide block 13, and the outer wall of the pressure spring 16 on the side away from the top plate 15 is fixedly connected to the inner wall of the slide cavity 14. When the push rod 17 is squeezed, the push rod 17 retracts into the slide cavity 14 after being pressed, pushing the top plate 15 to compress the pressure spring 16. At this time, the pressure spring 16 stores elastic potential energy to prepare for subsequent disassembly and popping open.

[0015] A filter screen 31 is fixedly connected to the inner wall of the filter element frame 3. A guide groove 32 is symmetrically opened on the outer wall of the filter element frame 3. A sliding groove 33 is symmetrically opened on the outer wall of the side of the filter element frame 3. A sliding rod 34 is symmetrically fixedly connected to the inner wall of the sliding groove 33. A pressing plate 35 is slidably connected to the outer wall of the sliding rod 34. A locking block 36 is fixedly connected to the outer wall of the pressing plate 35. A compression spring 37 is symmetrically fixedly connected to the outer wall of the pressing plate 35 on the side away from the locking block 36.

[0016] The compression spring 37 is fixedly connected to the outer wall of the pressing plate 35 and the inner wall of the slide groove 33. The outer wall of the filter element frame 3 is slidably connected to the inner wall of the mounting cavity 11. The inner wall of the guide groove 32 is slidably connected to the outer wall of the guide block 13. The inner wall of the guide groove 32 is in contact with the outer wall of the top rod 17. The guide groove 32 on the outer wall of the filter element frame 3 is aligned with the guide block 13 on the inner wall of the mounting cavity 11. The filter element frame 3 is manually pushed into the mounting cavity 11 along the guide block 13. The outer wall of the locking block 36 is slidably engaged with the inner wall of the locking groove 12. When the filter element frame 3 is pushed into the preset depth, the locking block 36 is precisely aligned with the locking groove 12. At this time, the compression spring 37 compressed by the pressing plate 35 releases elastic potential energy, pushing the pressing plate 35 to slide along the slide rod 34 towards the locking groove 12. Finally, the locking block 36 is inserted into the locking groove 12 and forms a sliding engagement.

[0017] In use, the mounting cavity 11 of the purifier 1 is the mounting carrier of the filter screen 31. The guide block 13 on its inner wall cooperates with the guide groove 32 of the filter element frame 3 to realize the guided installation of the installation path. The slot 12 of the mounting cavity 11 cooperates with the locking block 36 of the filter element frame 3, which is the core fixing structure after the filter screen 31 is installed. Align the filter element frame 3 with the assembled filter screen 31 with the mounting cavity 11 of the purifier 1, so that the guide groove 32 on the outer wall of the filter element frame 3 is aligned with the guide block 13 on the inner wall of the mounting cavity 11. Manually push the filter element frame 3 into the mounting cavity 11 along the guide block 13. At this time, the inner wall of the guide groove 32 will contact the end of the top rod 17 and continuously squeeze the top rod 17. After being pressured, the top rod 17 retracts into the sliding cavity 14, pushing the top plate 15 to compress the pressure spring 16. The pressure spring 16 stores elastic potential energy at this time, preparing for subsequent disassembly and opening. As the filter element holder 3 is continuously pushed in, the locking block 36 in its side slide groove 33 will gradually approach the slot 12 of the mounting cavity 11. When the filter element holder 3 is pushed in to the preset depth, the locking block 36 and the slot 12 are precisely aligned. At this time, the compression spring 37 compressed by the pressing plate 35 releases its elastic potential energy, pushing the pressing plate 35 to slide along the slide rod 34 towards the slot 12. Finally, the locking block 36 is inserted into the slot 12 and forms a sliding engagement. After the locking block 36 and the slot 12 are engaged, the filter element holder 3 is axially fixed in the mounting cavity 11 and cannot be pulled out at will. Finally, the grille plate 2 is fixed to the purifier 1 with screws, and the filter element holder 3 is fixed inside. The core of disassembly is "manually releasing the locking structure, using the elastic potential energy of the pressure spring 16 to spring open the filter element frame 3, achieving quick removal." Both hands simultaneously press the pressing plates 35 on both sides of the filter element frame 3. The pressing plates 35 slide along the slide rod 34 away from the slot 12, simultaneously compressing the compression spring 37. As the pressing plates 35 move, they cause the locking block 36 to exit from the slot 12, releasing the filter element frame 3 from the mounting cavity 11. When the locking block 36 is completely disengaged from the slot 12, the pressure spring 16 in the slide cavity 14 within the mounting cavity 11... No longer constrained by the snap-fit ​​structure, the previously stored elastic potential energy is released, pushing the top plate 15 to move out of the sliding cavity 14, thereby driving the push rod 17 to push out towards the guide groove 32; the push rod 17 applies an outward pushing force to the inner wall of the guide groove 32, popping the filter element frame 3 out of the mounting cavity 11 a short distance. After the filter element frame 3 is popped open, manually hold the exposed part of the filter element frame 3 and pull it outward along the direction of the guide block 13 to complete the disassembly of the filter screen 31. A new filter element frame 3 can be replaced or the filter screen 31 can be cleaned and maintained.
