[0002] Air purifiers, also known as air cleaners, air fresheners, and purifiers, refer to products that can absorb, decompose or transform various air pollutants and effectively improve air cleanliness. They can be used in home, commercial, industrial, building and other scenarios. The principle of air purifiers is to physically filter indoor air. Polluted air enters the machine through the air inlet, is filtered by the filter, and then the clean air is discharged from the air outlet. The filter life of an air purifier is generally only half a year, and it needs to be replaced regularly. If it is not replaced, it will cause secondary pollution. Small air purifiers can be placed on indoor desktops for use.

[0003] For example, a small indoor formaldehyde pollution purifier with the authorization announcement number CN216204096U and the authorization announcement date 2022.04.05 includes an outer shell, an upper dustproof net, a lower dustproof net, an activated carbon plate, a partition, a purification pipe, an air plate and a fan. The outer shell is cylindrical with both ends through, and the upper and lower ends of the outer shell are respectively installed with an upper dustproof net and a lower dustproof net. An activated carbon plate is installed inside the outer shell below the upper dustproof net, and a partition is installed inside the outer shell below the activated carbon plate. A number of evenly distributed ventilation holes are provided on the partition, and a purification pipe with a hollow tubular interior is installed at the bottom of the ventilation hole.

[0004] The shell and the air outlet cover of the air purifier are mostly connected by screws when assembled. Therefore, when cleaning or replacing the filter box, it is necessary to remove the multiple screws connecting the shell and the air outlet cover to separate the shell and the air outlet cover to replace the filter box. The operation process is relatively troublesome. Therefore, it is urgent to design a small air purifier to solve the above problems. Utility Model Content

[0024] The utility model provides a small air purifier, including a shell 1, an air outlet cover 2 is clamped on the top of the shell 1, and the shell 1 is provided with a cavity 3 inside which is slidably connected with an insert block 4, a socket 5 is integrally connected to the outer wall of the bottom of the air outlet cover 2, and the insert block 4 is inserted into the inside of the socket 5, a pull rod 6 is welded on the outer wall of one side of the insert block 4, and the pull rod 6 extends to the outside of the cavity 3, a first spring 7 connected to the insert block 4 is welded on the inner wall of the cavity 3, and the first spring 7 is sleeved on the outside of the pull rod 6, the pull rod 6 is pulled to drive the insert block 4 away from the inside of the socket 5, the air outlet cover 2 can be pulled up and removed from the shell 1 to replace the filter box 9, and there is no need to remove the screws, which is more convenient.

[0025] Beneficial effect: Pull the pull rod 6 to drive the plug block 4 away from the inside of the socket 5, move the air outlet cover 2 upward, and the air outlet cover 2 can be removed from the shell 1 to replace the filter box 9 without removing the screws, making the operation process more convenient.

[0026] In one embodiment provided by the present utility model, Figure 2 As shown, a support block 8 is provided on the inner wall of the shell 1, and a filter box 9 is placed on the top of the support block 8, and a supporting block 13 is provided on the outer wall of the bottom of the air outlet cover 2, which is in contact with the outer wall of the top of the filter box 9. After the air outlet cover 2 is fixed on the shell 1, the support block 8 and the supporting block 13 cooperate to clamp and fix the filter box 9.

[0027] In another embodiment provided by the present utility model, Figure 2 As shown, a coarse filter 10, a fine filter 11 and an activated carbon layer 12 are sequentially arranged on the inner wall of the filter box 9 from bottom to top, and a fan 14 is fixed to the inner wall of the housing 1 by bolts.

[0028] In another embodiment provided by the present utility model, Figure 1 , 2 and Figure 4 As shown, dust covers 15 are clamped on the outer walls of both sides of the shell 1, and connecting blocks 16 are integrally connected to the outer walls of the top and bottom of the dust cover 15, so that the dust cover 15 can play a dustproof effect.

[0029] In one embodiment provided by the present utility model, Figure 4 As shown, the interior of the connecting block 16 is slidably connected with a fixing block 17 , and a second spring 20 connected to the fixing block 17 is welded on the inner wall of the connecting block 16 .
