[0027] It should be noted that all directional indications (such as up-down-left-right-front-back...) in the embodiments of the present application are only used to explain the relative positional relationship between the components, the movement condition, etc. in a certain posture (as shown in the drawings). If the certain posture changes, the directional indications also change accordingly. The connection can be direct connection or indirect connection.

[0028] As Figures 1-7As shown, a filter screen quick release assembly for quick release of a filter screen, comprising a housing 1 and a first mounting bracket 2 and a second mounting bracket 3 fixed on the housing 1, the first mounting bracket 2 and the second mounting bracket 3 are oppositely arranged and a filter screen 4 is clamped therebetween, a receiving hole 21 is formed in the middle of the first mounting bracket 2, a clamping plate 5 is arranged in the receiving hole 21 and slides along the receiving hole 21, the clamping plate 5 abuts against the end of the filter screen 4 to clamp the filter screen 4, and an elastic assembly 6 is arranged at the end of the clamping plate 5 away from the filter screen 4, the elastic assembly 6 provides elastic force so that the clamping plate 5 is clamped at the end of the filter screen 4.

[0029] By arranging the telescopic clamping plate 5 in the middle of the first mounting bracket 2 and clamping the end of the filter screen 4 by the clamping plate 5, the filter screen 4 is clamped and fixed in the housing 1; when disassembling, the filter screen 4 can be pulled out and disassembled by overcoming the resistance between the clamping plate 5 and the filter screen 4 through external force, so that the filter screen 4 can be fixed during use and quickly disassembled during disassembly; when replacing, the new filter screen 4 is pushed into the space between the clamping plate 5 and the second mounting bracket 3, the filter screen 4 presses the clamping plate 5 so that the clamping plate 5 is retracted into the receiving hole 21, thereby facilitating the installation of the filter screen 4 between the first mounting bracket 2 and the second mounting bracket 3, and through the cooperation of the above structure, the disassembly and installation of the filter screen 4 are facilitated.

[0030] Specifically, a guide slope 51 is arranged at the end of the clamping plate 5 close to the filter screen 4. During installation of the filter screen 4, the end of the clamping plate 5 close to the second mounting bracket 3 is inserted into the area between the first mounting bracket 2 and the second mounting bracket 3 when the filter screen 4 is not installed, at this time the filter screen 4 is pushed into the space between the first mounting bracket 2 and the second mounting bracket 3 by external force, the filter screen 4 slides along the guide slope 51 and presses the clamping plate 5, so that the clamping plate 5 is retracted into the receiving hole 21; the guide slope 51 is arranged to guide the filter screen 4 to slide and press the clamping plate 5 to retract into the receiving hole 21.

[0031] Specifically, a first limiting rib 22 protruding towards the second mounting bracket 3 is arranged on the first mounting bracket 2, and a second limiting rib 31 protruding towards the first mounting bracket 2 is arranged on the second mounting bracket 3, the first limiting rib 22 and the second limiting rib 31 are used to limit the outer wall of the filter screen 4 by matching the shape of the filter screen 4; an open structure is formed on the first limiting rib 22 and the second limiting rib 31 to avoid the filter screen 4 when the filter screen 4 is radially extracted.

Avoiding that the clamping plate 5 moves too much when the filter screen 4 is removed, the guide inclined surface 51 is away from the accommodating hole 21, so that the clamping plate 5 and the second mounting frame 3 form a step, which is not conducive to the installation of the filter screen 4.

[0034] Specific, the elastic component 6 includes a fixed cylinder 61 fixed on the shell and a telescopic column 62 slidably connected in the fixed cylinder 61, the telescopic column 62 is fixed on the clamping plate 5, the fixed cylinder 61 is provided with a spring 63, and the spring 63 is abutted against the end of the telescopic column 62 away from the clamping plate 5. The spring 63 provides elastic force, so that the telescopic column 62 abuts against the clamping plate 5 and is clamped on the filter screen 4 in the direction of the second mounting frame 3.

[0035] Specific, the filter screen 4 is cylindrical, and the first limiting rib 22 and the second limiting rib 31 are semicircular and match the outer circle of the filter screen 4.

[0036] Specific, the shell 1 is clamped with a cover plate 11, and the cover plate 11 is arranged opposite to the open end of the first limiting rib 22. By removing the cover plate 11, the filter screen 4 in the shell 1 can be taken out and replaced. Specifically, the shell 1 is also provided with a ventilation grid hole, so that air enters the shell 1 and is filtered by the filter screen 4.

[0037] The utility model also provides a kind of filter, it includes above quick release assembly.
