[0038] Through main body 10 has through cavity 11, through main body 10 is opened with air inlet 12 that communicates through cavity 11 in bottom, through main body 10 is opened with through port 13 that communicates through cavity 11 in upper portion, when, air inlet 12 and through port 13 are communicated by through cavity 11, can form a air outlet channel for passing air.

[0039] Inner sleeve 20 is fixedly arranged in through cavity 11, inner sleeve 20 is cylindrical structure, bottom is fixedly connected with the side wall of through main body 10 at through cavity 11, top is open, and the top opening of inner sleeve 20 is opposite to through port 13.In the example embodiment, air inlet 12 is multiple, with the axis of inner sleeve 20 as center, multiple air inlets 12 are distributed around the circumference, to realize multi-point air intake by multiple air inlets 12.

[0040] The first sliding member 31 is in a cylindrical structure and is slidably arranged inside the inner sleeve 20. The first sliding member 31 is provided with a first blocking member 41 at an end thereof facing the through port 13.
