Description

Technical Field

[0001] This utility model relates to the field of purification filter technology, and in particular to a novel purification filter. Background Technology

[0002] Air filters, also known as air purification filters, are divided into four types: coarse, medium, sub-high efficiency, and high efficiency. Depending on the air volume, different numbers of air filters are installed in a duct. The filter section is installed in a central air conditioning system to filter out dust particles from the air supplied to the room, thereby achieving high-quality indoor air.

[0003] Existing air purification filters and frames are mostly integrated structures or connected by bolts. When the filter needs to be replaced or cleaned, the frame and filter must be disassembled together. After disassembly, the filter can be removed for cleaning and replacement. However, the frame structure is relatively complex to install, requiring multiple screws for fastening. Furthermore, some installation locations are quite narrow, making installation and disassembly difficult, and failing to achieve a filter structure that allows for easy removal and disassembly. To overcome these disadvantages, this utility model provides a novel air purification filter. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel purification filter.

[0006] Furthermore, ear plates are fixedly connected to the four corners of the mounting frame.

[0007] Furthermore, the filter assembly includes a connecting frame, a filter screen is fixedly connected inside the connecting frame, and sealing grooves are provided on both the front and rear sides of the filter screen, with grooves provided on both sides inside the sealing grooves.

[0008] Furthermore, the limiting component includes a fixed frame that is rotatably connected to the second limiting frame. The fixed frame has slots on both sides of its bottom end, and each slot has a locking component inside it.

[0009] Furthermore, a second spring is fixedly connected to the middle position inside the slot, and limit rods are fixedly connected to both sides inside the slot. A sliding groove is provided on the front side of the slot.

[0010] Furthermore, the locking assembly includes a mounting block slidably connected to the limiting rod, the mounting block being fixedly connected to the second spring, a sealing frame being bolted to the bottom of the slot, a locking block being fixedly connected to the bottom of the mounting block, a connecting plate being fixedly connected to the upper end of the mounting block and slidably connected to the slide groove, a push plate being fixedly connected between the connecting plates, and a locking bolt being threaded onto the push plate.

[0011] Furthermore, sealing grooves are provided on both the front and rear sides of the connecting frame, and sealing rings are fixedly connected to both the front side of the third limiting frame and the rear side of the fixing frame.

[0012] The beneficial effects of this utility model are:

[0013] In use, this novel purification filter can improve the sealing performance between the limiting component, the sealing component, and the third sealing frame through the setting of the sealing ring and sealing groove.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-10 As shown, a novel purification filter is disclosed, comprising an installation frame 1, a first limiting frame 5 fixedly connected inside the installation frame 1, a second limiting frame 7 fixedly connected inside the first limiting frame 5, a third limiting frame 9 fixedly connected inside the second limiting frame 7, slots 6 being provided at both ends of the bottom inner side of the first limiting frame 5, a first spring 8 fixedly connected to the middle position of the front side of the second limiting frame 7, a limiting component 4 rotatably connected inside the first limiting frame 5, and a filter component 3 disposed inside the second limiting frame 7.

[0029] As shown in the figure, ear plates 2 are fixedly connected to the four corners of the mounting frame 1. The device can be fixed to the air intake pipe through the ear plates 2 to filter the air entering the air intake pipe.

[0030] As shown in the figure, the filter assembly 3 includes a connecting frame 23, a filter screen 24 is fixedly connected inside the connecting frame 23, and sealing grooves 25 are provided on both the front and rear sides of the filter screen 24. Grooves 26 are provided on both sides inside the sealing grooves 25. Sealing grooves 25 are provided on both the front and rear sides of the connecting frame 23. Sealing rings 10 are fixedly connected to the front side of the third limiting frame 9 and the rear side of the fixed frame 11. After the sealing assembly is placed on the second limiting frame 7, the limiting assembly 4 is closed. The sealing rings 10 can be engaged with the sealing grooves 25, thereby improving the sealing performance.

[0031] As shown in the figure, the limiting component 4 includes a fixed frame 11 rotatably connected to the second limiting frame 7. The fixed frame 11 has slots 19 on both sides of its bottom end, and each slot 19 contains a locking component 16. A second spring 21 is fixedly connected to the middle position inside the slot 19. Limiting rods 22 are fixedly connected to both sides inside the slot 19. A sliding groove 20 is provided on the front side of the slot 19. The locking component 16 includes a mounting block 17 slidably connected to the limiting rod 22. The mounting block 17 is fixedly connected to the second spring 21. A sealing frame 15 is bolted to the bottom end of the slot 19. The bottom end of the mounting block 17... A locking block 18 is fixedly connected. A connecting plate 14 that is slidably connected to the slide groove 20 is fixedly connected to the upper end of the mounting block 17. A push plate 12 is fixedly connected between the connecting plates 14. A locking bolt 13 is threadedly connected to the push plate 12. When the sealing assembly needs to be disassembled, the locking bolt 13 is loosened and the push plate 12 is pushed upward. The connecting plate 14 moves along the slide groove 20, which drives the mounting plate to compress the spring along the limit rod 22. This allows the locking block 18 to disengage from the slot 6. The first spring 8 can drive the fixing frame 11 to pop outward, thereby releasing the fixing of the sealing assembly.

[0032] Working principle: During use, the sealing ring 10 and sealing groove 25 improve the sealing performance between the limiting component 4, the sealing component, and the third limiting frame 9. Specifically, after placing the sealing component on the second limiting frame 7 and then closing the limiting component 4, the sealing ring 10 can engage with the sealing groove 25, thereby improving the sealing performance. The limiting component 4 can limit and fix the sealing component, and the limiting component 4 is engaged with the slot 6 via the locking block 18, facilitating disassembly and installation, and thus making it easy to disassemble, replace, and clean the sealing component. Specifically, the fixing frame 11 rotates around the first limiting frame 5, and the locking block 18 contacts the first limiting frame 5. Afterwards, the arc-shaped structure of the locking block 18 can slide along the first limiting frame 5, thereby driving the mounting block 17 to push the second spring 21 to retract along the limiting rod 22 until the locking block 18 is locked inside the slot 6. Then, tighten the locking bolt 13 to fix the fixed frame 11 and then the sealing assembly. When the sealing assembly needs to be disassembled, loosen the locking bolt 13, push the push plate 12 upward, and move the connecting plate 14 along the slide groove 20 to drive the mounting plate to compress the spring along the limiting rod 22, thereby allowing the locking block 18 to disengage from the slot 6. The first spring 8 can drive the fixed frame 11 to pop outward, thereby releasing the fixation of the sealing assembly.
