In this utility model, a sliding window is taken as an example for detailed description.

As shown in FIG. 1 , the push-pull device 1 includes a first slide 10 and a first push-pull fan 20 . Wherein, from the indoor to the outdoor direction, the first slide 10 includes a first frame 101 , a first slide rail 102 and a second frame 103 in sequence. The first sliding fan 20 includes a first fan frame 201 and a second fan frame 202 . The first push-pull fan 20 can be installed on the first slide 10 , so that the first push-pull fan 20 can slide on the first slide 10 . In the installed state, the first sash frame 201 is located between the first slide rail 102 and the second frame 103 , and the second frame 103 is located between the first sash frame 201 and the second sash frame 202 .

In wind and rain, after rainwater seeps into the room, it flows into the "U"-shaped second tank body 400 along the glass. As shown in Figure 2, since the closed isobaric chamber 300 is in a closed state, a pressure difference is formed between the indoor and the outdoor, and as the rainwater seeping into the room gradually increases, the rainwater flowing into the "U"-shaped second tank 400 The formed pressure is gradually equal to the outdoor pressure, forming an equal pressure. If rainwater further infiltrates into the "U"-shaped second tank body 400, the water pressure in the "U"-shaped second tank body 400 is greater than the outdoor pressure, so that the third frame 302 and the second slide rail 301 The one-way drain valve at the through hole on the roof will be opened, and the rainwater will be discharged outside.
