The chemical filter of the purifier needs to be replaced regularly to ensure the best effect of air adsorption, so a long-life chemical filter is needed.

[0003] The structure of existing chemical filters mostly uses an alloy frame to cover the chemical filter and then install it in the purifier. The alloy frame and the chemical filter are fixed and non-detachable structures, which are inconvenient to install and disassemble, and may reduce its service life. In addition, the filter mostly adopts a single-layer structure, with low filtration efficiency and reduced practicality. Utility Model Content

[0004] The purpose of the utility model is to provide a long-life chemical filter to solve the problem that the structure of the existing chemical filter proposed in the above background technology mostly adopts an alloy frame to cover the chemical filter and then install it in the purifier.

In addition, the filter mostly adopts a single-layer structure, the filtration efficiency is low, and the practicality is reduced.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a long-life chemical filter, including a mounting plate, wherein both sides of the top and bottom of the mounting plate are provided with slots, round rods are fixedly installed inside the slots, both sides of the surface of the round rods are movably sleeved with sliders, the tops of the sliders are fixedly installed with a card plate, a locking spring is fixedly installed between the sliders and the slots, the inner surface of the locking spring is movably connected to the outer surface of the round rod, the top and bottom of the mounting plate are movably installed with filters, and the four corners of the bottom of the filter are fixedly installed with blocks.

[0006] Preferably, a filter plate is movably installed inside the mounting plate, fixing blocks are fixedly installed at both ends of the filter plate, fixing grooves are opened on both sides of the top of the mounting plate, and the fixing blocks are matched with the fixing grooves.

[0007] Preferably, a bolt is rotatably mounted on the top of the fixing block, and the bottom of the bolt passes through the fixing block and extends to the inside of the mounting plate.

[0008] Preferably, both sides of the interior of the mounting plate are provided with strip grooves, and telescopic rods are fixedly installed inside the strip grooves.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] During daily use of the long-life chemical filter, the operator moves the filter, and the movement of the filter will drive the card block to slide synchronously. At this time, the card block is aligned between the card slot and the card plate, and then the card block is continuously pressed down. At the same time, the outer surface of the card block will continuously squeeze the outer surface of the card plate. Due to the limiting effect of the round rod, the card plate will drive the slider to move oppositely inside the card slot, thereby squeezing the locking spring to put it in a compressed state. When the card block is placed between the card plates, the locking spring will rebound and the mounting plate can be installed through the card plate and the card block, which is convenient for replacement, thereby extending its service life.

[0013] During daily use, the long-life chemical filter is distributed at the top and bottom of the mounting plate, and the mesh numbers and sizes of the filters are different. At the same time, when used in conjunction with the filter plate in the middle, multiple filtration can be achieved, thereby improving its filtration efficiency and increasing its practicality.

A card plate 5 is fixedly installed on the top of the slider 4, and the slider 4 will drive the card plate 5 to slide synchronously when sliding, and a locking spring 6 is fixedly installed between the slider 4 and the card slot 2, and the slider 4 will squeeze the locking spring 6 when sliding, so that it is in a compressed state. The inner surface of the locking spring 6 is movably connected to the outer surface of the round rod 3. The top and bottom of the mounting plate 1 are movably installed with filter screens 7. There are two filter screens 7. The mesh numbers and sizes of the two filter screens 7 are different. Blocks 8 are fixedly installed at the four corners of the bottom of the filter screen 7. The mounting plate 1 can be installed through the block 8 and the card plate 5. A filter plate 9 is movably installed inside the mounting plate 1. The filter plate 9 can cooperate with the filter screen 7 to achieve multiple filtration. Fixed blocks 10 are fixedly installed at both ends of the filter plate 9. Fixed grooves 11 are provided on both sides of the top of the mounting plate 1, and the fixed blocks 10 are adapted to the fixed grooves 11. When the filter plate 9 slides, it will drive the fixed block 10 to slide synchronously.

[0021] The top of the fixing block 10 is rotatably mounted with a bolt 12, and the bottom of the bolt 12 penetrates the fixing block 10 and extends to the inside of the mounting plate 1. The bolt 12 is rotated and screwed into the inside of the fixing block 10 and the mounting plate 1 to install the filter plate 9. Both sides of the inside of the mounting plate 1 are provided with strip grooves 13, and the inside of the strip grooves 13 are fixedly installed with telescopic rods 14. Both sides of the top and bottom of the mounting plate 1 are provided with square grooves 17, which are connected to the strip grooves 13, and the inside of the square grooves 17 are movably installed with movable blocks 15, which are movable. The block 15 is adapted to the strip groove 13, and a movable spring 16 is fixedly installed between the movable block 15 and the strip groove 13, and the inner surface of the movable spring 16 is movably connected to the outer surface of the telescopic rod 14. The movable block 15 will squeeze the movable spring 16 when sliding, so that it is in a compressed state. A movable groove 18 is opened at one end of the mounting plate 1. The number of the movable grooves 18 is four, and the four movable grooves 18 have the same size. The movable groove 18 is adapted to the block 8, and the movable filter 7 can drive the block 8 to slide out from the inside of the movable groove 18.

[0022] Working principle: When the chemical filter needs to be installed and used, the operator moves the filter plate 9, and the filter plate 9 will drive the fixed block 10 to move. At this time, the fixed block 10 is placed between the inside of the fixed groove 11 and the mounting plate 1, and the bolt 12 is placed on the top of the fixed block 10. Then the bolt 12 is turned and screwed into the inside of the fixed block 10 and the mounting plate 1 to install the filter plate 9. Next, the operator moves the filter screen 7, and the movement of the filter screen 7 will drive the block 8 to slide synchronously. At this time, align the block 8 between the slot 2 and the card plate 5, and then continue to press down the block 8. At the same time, the outer surface of the block 8 will continuously squeeze the outer surface of the card plate 5. Due to the limiting effect of the round rod 3, the card plate 5 will drive the slider 4 to move back and forth inside the slot 2. The locking spring 6 is compressed when the clamping block 8 is placed between the clamping plates 5, and the locking spring 6 rebounds, so that the mounting plate 1 can be installed through the clamping plate 5 and the clamping block 8. Finally, the operator slides the filter screen 7, and the movement of the filter screen 7 drives the clamping block 8 to slide synchronously, which drives the movable block 15 to slide inside the strip groove 13, thereby squeezing the telescopic rod 14 and the movable spring 16, so that the movable block 15 is inside the strip groove 13, and at the same time drives the clamping block 8 at the other end to reach the inside of the movable groove 18, and then pulls the filter screen 7 upward or downward to drive the clamping block 8 to disengage from the inside of the square groove 17, so that it can be disassembled, thereby regularly replacing the mounting plate 1 to extend its service life.
