DETAILED DESCRIPTION

[0025] The following is a specific embodiment of the present application and further describes the technical solution of the present application in combination with the drawings, but the present application is not limited to these embodiments.

[0026] A simple air filter that can be easily disassembled and assembled, as shown in Figures 1 to 6 includes an outer shell 1, the outer shell 1 is provided with a filter core 2, the outer shell 1 is formed by splicing an upper shell 111 and a lower shell 112, the lower surface of the upper shell 111 abuts against the upper surface of the lower shell 112, so as to ensure the relative stability of the two.

[0027] The lower shell 112 is provided with a limiting groove 16 for limiting the filter core 2, the limiting groove 16 is matched with the filter core 2, the filter core 2 is limited by the limiting groove 16, thereby ensuring the stability of the filter core 2.

[0028] The lower shell 112 is provided with an air inlet 3 and an air outlet 4, and the upper shell 111 is provided with a spare port 14. A plug 15 is detachably connected to the upper shell 111 to block the spare port 14. In this embodiment, the plug 15 is clamped on the upper shell 111 and can be disassembled by external force. Alternatively, the plug 15 is threadedly connected to the upper shell 111. Under normal circumstances, the spare port 14 is blocked by the plug 15 to prevent air and external impurities from entering. During maintenance, the plug 15 can be removed to balance the air pressure inside and outside the shell 1, thereby facilitating the disassembly of the upper shell 111 and the lower shell 112 and reducing the operation difficulty and risk.

[0029] The sidewall of the upper shell 111 is provided with a plurality of locking blocks 5 uniformly distributed along the circumference of the upper shell 111. The sidewall of the lower shell 112 is provided with a plurality of limiting blocks 6 corresponding to the locking blocks 5, which are uniformly distributed along the circumference of the lower shell 112. When the upper shell 111 rotates relative to the lower shell 112, the locking blocks 5 and the limiting blocks 6 can be cooperatively locked or unlocked.

[0030] As to how the locking blocks 5 and the limiting blocks 6 cooperatively lock, it should be noted that the locking block 5 includes a locking portion 51 and a limiting portion 52. The locking block 5 is in the shape of "L" and has a certain deformation capacity. When the upper shell 111 rotates relative to the lower shell 112, the upper surface of the locking portion 51 can abut against the lower surface of the limiting block 6. At this time, the relative locking force formed by the interaction of the locking portion 51 and the limiting block 6 prevents the upper shell 111 and the lower shell 112 from separating. Since the lower surface of the upper shell 111 abuts against the upper surface of the lower shell 112 in the combined state, the upper shell 111 and the lower shell 112 can maintain a relatively stable state when the locking blocks 5 and the limiting blocks 6 cooperatively lock.

[0031] Further, when the upper shell 111 rotates relative to the lower shell 112, the sidewall of the limiting portion 52 can abut against the sidewall of the limiting block 6. It should be noted that the limiting of the limiting block 6 by the limiting portion 52 ensures the stable relative position of the limiting portion 52 and the locking portion 51 during assembly, thereby reducing the operation difficulty and improving the assembly efficiency. Moreover, it can further ensure that the locking blocks 5 and the limiting blocks 6 stably cooperatively lock.

[0032] Furthermore, the sidewall of the upper shell 111 is provided with a deformable portion 8, and the deformable portion 8 is provided with a positioning block one 9. The sidewall of the lower shell 112 is provided with a plurality of positioning block twos 10. The sidewall of the positioning block one 9 can abut against the sidewall of any one of the positioning block twos 10 to limit the rotation of the upper shell 111 relative to the lower shell 112.

[0033] It should be noted that after the upper shell 111 and the lower shell 112 are assembled, the lower surface of the upper shell 111 abuts against the upper surface of the lower shell 112, the upper surface of the locking portion 51 abuts against the lower surface of the limiting block 6, the upper shell 111 and the lower shell 112 cannot move towards each other or move in the opposite direction, and the side wall of the limiting portion 52 abuts against the side wall of the limiting block 6, and the side wall of the positioning block one 9 abuts against the side wall of one of the positioning block twos 10. At this time, the upper shell 111 and the lower shell 112 cannot rotate relative to each other, that is, the upper shell 111 and the lower shell 112 remain relatively fixed after being assembled.

[0034] The locking portion 51 is provided with a guide inclined surface 7 for guiding the limiting block 6. The guide inclined surface 7 extends from low to high from the side wall of the locking portion 51 to the upper surface of the locking portion 51. During assembly, as the upper shell 111 rotates, the limiting block 6 on the lower shell 112 moves along the guide inclined surface 7. Through the guiding effect of the guide inclined surface 7 on the limiting block 6, it is ensured that the upper surface of the locking portion 51 can abut against the lower surface of the limiting block 6 smoothly, the cooperation and locking of the locking block 5 and the limiting block 6 are completed, and the difficulty of assembly is reduced.

[0035] As to how to release the locking of the locking block 5 and the limiting block 6, it should be noted that the upper shell 111 is rotated relative to the lower shell 112 by overcoming the relative locking force formed by the interaction of the locking portion 51 and the limiting block 6 through external force, the locking portion 51 moves away from the limiting block 6 until they are separated, and at this time the locking of the locking block 5 and the limiting block 6 is released.

[0036] It should be noted that during disassembly, the deformable portion 8 is deformed by external force, and then the positioning block one 9 moves away from the positioning block two 10, so that when the upper shell 111 is rotated, the side wall of the positioning block one 9 cannot abut against the side wall of the positioning block two 10.

[0037] Further, the deformable portion 8 is provided with a force applying portion 13, and the operator can hold the force applying portion 13 to deform the deformable portion 8, which is convenient for the operator to operate.

[0038] The side wall of the lower shell 112 is provided with a plurality of support blocks 11 for supporting the positioning block one 9. The plurality of support blocks 11 are uniformly distributed along the circumference of the lower shell 112. In this way, not only the structural strength of the lower shell 112 can be improved, but also after the deformable portion 8 is deformed and then the upper shell 111 is rotated, the outer side wall of the support block 11 abuts against the inner side wall of the positioning block one 9, thereby supporting the positioning block one 9, that is, the deformable portion 8 can still be restricted to restore without external force.

[0039] The side wall of the positioning block one 9 relative to the support block 11 is provided with an inclined surface 12, which is gradually inclined outward from top to bottom. When the upper shell 111 and the lower shell 112 are separated after the locking of the locking block 5 and the limiting block 6 is released, the support block 11 will move along the inclined surface 12, thereby reducing the resistance caused by the contact between the support block 11 and the positioning block one 9 when the upper shell 111 and the lower shell 112 are separated.

[0040] During assembly, the upper shell 111 and the lower shell 112 are combined, and then the upper shell 111 is rotated, so that the upper surface of the locking part 51 abuts against the lower surface of the limiting block 6, until the side wall of the limiting part 52 abuts against the side wall of the limiting block 6, that is, the assembly is completed; during disassembly, only the deformable part 8 is deformed by holding the force applying part 13 and applying external force, and then the upper shell 111 is reversely rotated, so that the locking part 51 is away from the limiting block 6 until they are separated, and then the upper shell 111 and the lower shell 112 are separated, that is, the disassembly is completed, which is simple in operation, convenient in disassembly and assembly, and can effectively improve the disassembly and assembly efficiency.

[0041] The specific embodiments described herein are merely illustrative of the spirit of the utility model; those skilled in the art to which the utility model belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the utility model or exceed the range defined by the appended claims.
