[0037] Further, the clamping portion 350 includes: a first clamping position 351 and a second clamping position 352, which are arranged at intervals along the axial direction of the first column 110; when the valve cover 100 is pressed from being matched with the first clamping position 351 to being matched with the second clamping position 352, the first column 110 pushes against the second column 320, so that the second column 320 pulls the rib 330 and drives the clamping jaw 311 to shrink along the radial direction of the second column 320.

[0038] When the waterproof and breathable valve needs to be disassembled, the valve cover 100 is first pressed, so that it is pressed from being matched with the first clamping position 351 to being matched with the second clamping position 352, at this time the buckle 310 is unlocked, and then the valve cover 100 and the valve body 300 are pulled outwards, so that the valve body 300 can be pulled out of the mounting hole of the shell 400.

[0039] Further, the valve cover 100 is provided with a sleeve portion 120 surrounding the plurality of support portions 340, and the inner wall of the sleeve portion 120 is provided with a clamping ring 130 matched with the clamping portion 350. In the initial assembly state, the clamping ring 130 is matched with the first clamping position 351; when the waterproof and breathable valve needs to be disassembled, the valve cover 100 can be pressed until the clamping ring 130 is matched with the second clamping position 352, at this time the buckle 310 will be in the unlocked state of radial shrinkage.

[0040] In addition, the valve body 300 is provided with an annular groove 360 corresponding to the sleeve portion 120, and when the valve cover 100 is pressed, the sleeve portion 120 can be inserted into the annular groove 360, so that the compactness of the structure is improved.
