[0035] Clamping block 38 and clamping groove 36 are slidably connected, and disc 34 is located between first ventilation pipe 1 and second ventilation pipe 2, and the upper end of filter screen disc 37 is attached to the lower end of first ventilation pipe 1, and the lower end of filter screen disc 37 is attached to the upper end of second ventilation pipe 2.

[0036] In the embodiment, filter screen disc 37 is limited in the inside of circular groove 35 by the mutual cooperation of clamping block 38 and clamping groove 36, first ventilation pipe 1 and second ventilation pipe 2 are connected into a whole by disc 34, and the inside air of first ventilation pipe 1 and second ventilation pipe 2 is in the state of mutual communication by filter screen disc 37.

[0037] Example 2

[0038] As Figures 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the auxiliary component 4 includes a second connecting plate 41 fixedly connected to the outer surface of the lower edge of the first ventilation pipe 1, a first electric push rod 42 fixedly connected to the outer edge of the second connecting plate 41, an auxiliary block 43 fixedly connected to the output end of the first electric push rod 42, an arc-shaped block 44 fixedly connected to the outer end of the auxiliary block 43, the arc-shaped block 44 being located on the inner edge of the filter screen 37, and the arc-shaped block 44 being in contact with the inner edge of the filter screen 37.
