[0030] Reference Figure 1-5This utility model embodiment proposes a household air purifier filter that is easy to assemble and disassemble, including a plug plate 1. A filter cover 2 is embedded through one side of the outer wall of the plug plate 1. A filter layer 3 is provided on the inner side wall of the filter cover 2. Two guide strips 6 are symmetrically arranged at the top and bottom of the plug plate 1. An air purifier is provided on the outer side of the plug plate 1 for insertion. A lock hole for a locking block 55 to be inserted is opened on the inner side wall of the air purifier, and a guide groove for the guide strips 6 to be slidably inserted is opened on the inner side wall of the air purifier. Through the cooperation of the plug plate 1 and the air purifier, the plug plate 1 is connected to the air purifier, which facilitates the assembly and disassembly of the plug plate 1. The plug plate 1 can be accurately inserted into the air purifier through the guidance of the guide strips 6.

[0031] The insert plate 1 has a cavity 4 that is connected to its top and outer side wall. The bottom of the cavity 4 is provided with an active spring 51 in the self-locking plug 5. The top of the active spring 51 is provided with a pressure plate 52. One side of the pressure plate 52 is provided with an L-shaped bend, and the other side of the pressure plate 52 is provided with an upward vertical part. The L-shaped bend makes it easy to apply pressure to the pressure plate 52 with fingers when disassembling the insert plate 1, thereby moving the pressure plate 52. The vertical part provides space for the lifting and lowering movement of the locking block 55. The top of the pressure plate 52 has a groove 53. The bottom of the groove 53 is provided with a passive spring 54. The top of the passive spring 54 is provided with a locking block 55. One side of the top of the locking block 55 has an inclined surface. The inclined surface ensures that when the locking block 55 comes into contact with the air purifier, the locking block 55 can move vertically downward.

[0032] Four circular holes 7 and four outer arc grooves 8 are axially and equally spaced on one side of the outer wall of the insert plate 1, near the outer circumference of the filter screen cover 2. Each circular hole 7 is connected to its corresponding outer arc groove 8. An inner arc groove 9 is formed inside the insert plate 1 near the four outer arc grooves 8, and the inner arc grooves 9 are connected to the outer arc grooves 8. Four support blocks 10 are axially and equally spaced on one side of the outer wall of the filter screen cover 2. A round rod 11 is provided on the outer wall. The inner frame of the outer arc groove 8 and the outer diameter of the round rod 11 are the same, ensuring that the round rod 11 can move axially and circumferentially within the outer arc groove 8. A disc 12 is provided at one end of the round rod 11. The inner diameter of the round hole 7 and the disc 12 is the same as the inner width of the inner arc groove 9, ensuring that the disc 12 can move circumferentially within the inner arc groove 9 after being inserted into the round hole 7. A counterweight 13 is provided on the inner side wall of the filter screen cover 2 near the filter screen layer 3.

[0033] The specific implementation method is as follows: When installing the filter layer 3 between the filter layer 3 and the air purifier, first insert the filter cover 2 on the outer wall of the filter layer 3 through the insert plate 1. When inserting and connecting, adjust the counterweight 13 on the filter cover 2 to a 45-degree tilt position, and then align the disc 12 with the round hole 7. After the disc 12 passes through the round hole 7, it is inserted into the inner arc groove 9. Rotate the filter cover 2 and rotate it 45 degrees. The counterweight 13 rotates to the bottom. The outer arc groove 8 limits the disc 12, which can prevent the filter cover 2 from falling off. When disassembling, simply rotate the filter cover 2 in the opposite direction by 45 degrees, and then pull the filter cover 2 out horizontally. The filter cover 2 is easy to install and remove.

[0034] Align the insert plate 1 with the corresponding slot on the air purifier, and use the guide strip 6 for guidance and limiting. As the insert plate 1 is inserted, the locking block 55 contacts the air purifier. After being pressed, the locking block 55 moves vertically downward along the pressure plate 52, and the passive spring 54 is compressed. When the locking block 55 moves directly below the lock hole on the air purifier, the pressure lost by the locking block 55 disappears. Under the action of the rebound force of the passive spring 54, the passive spring 54 pushes the locking block 55 into the lock hole, realizing the positioning and installation of the insert plate 1. When disassembling, use two fingers to insert into the cavity 4 and press the two pressure plates 52 to move towards each other. The pressure plates 52 drive the locking block 55 to disengage from the lock hole. Then, pull out the insert plate 1 to realize convenient disassembly and assembly of the insert plate 1.
