In the present invention, a sliding window will be described in detail as an example.

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 sliding 10 includes a first frame 101, a first sliding rail 102 and a second frame 103 in this order. 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 mounted above the first slide 10 such that the first push-pull fan 20 can slide over the first slide 10. In the installed state, the first frame 201 is located between the first rail 102 and the second frame 103, and the second frame 103 is located between the first frame 201 and the second frame 202.

A seal is disposed between the first rail 102 and the first frame 201, and a seal is disposed between the second frame 103 and the second frame 202, such that the first rail 102, the first frame 201, and the second frame 103 are disposed. A first enclosed isostatic chamber 100 is formed between the second frame 202 and the second frame 202. At least two through holes are disposed on the first sliding rail 102, and at least two through holes in the first sliding rail 102 are provided with a drainage device (not shown) with a one-way drainage valve, and the second frame 103 is provided with at least Two through holes, at least two through holes provided in the second frame 103 are provided with drainage (not shown) with a one-way drain valve. Wherein the seal can be any seal, such as a sealing strip.

In addition, as shown in FIG. 1 , a first slot body 200 is formed between the first frame 101 and the first slide rail 102 and the first sliding fan 2 , for example, a “U”-shaped first slot body 200 for receiving Infiltration of rain.

That is, the push-pull device 1 provided by the present invention has a through hole provided on the first slide rail 102 and the second frame 103 with a drain device with a one-way drain valve, which is closed under normal conditions, so that A closed isostatic chamber 100 is formed between the first rail 102 and the second frame 103 of the first sliding 10 and the first and

second frame

201 and 202 of the first sliding fan 20.

In practice, for example, in the event of wind and rain, when the sliding window is closed, there must be a pressure difference between the indoor and outdoor. Therefore, for the sliding window, no matter how tight the seal is, the rain will enter the room under the wind and rain. And as the outdoor wind pressure increases, the rate of rainwater infiltration will also increase. In order to allow the rainwater entering the room to be smoothly discharged outside, the push-pull device provided by the present invention provides one of the above-described closed-type equal pressure chambers 100 and a "U"-shaped first tank body 200 for accommodating rainwater. In the rain and rain, after the rainwater penetrates into the room, it flows into the "U"-shaped first tank 200 along the glass. As shown in FIG. 2, since the closed type isostatic chamber 100 is in a closed state, a pressure difference is formed between the indoor and outdoor, and as the rainwater that has infiltrated into the room gradually increases, the rainwater flowing into the "U"-shaped first tank 200 is caused. The pressure formed is gradually equal to the pressure outside, forming an equal pressure. If the rainwater further penetrates into the "U"-shaped first tank body 200, the "U"-shaped first tank body 200 The water pressure is greater than the outdoor pressure, so that the one-way drain valve provided at the through hole on the first rail 102 and the second frame 103 is opened, and the rainwater is discharged outside. Specifically, as shown in FIG. 2, the rainwater in the first tank body 200 of the "U" shape is shown to flow out through the first sliding hole 102 and the through hole provided in the second frame 103, and passes through the second sliding 301. And the third frame 302 flows out of the outdoor, and its flow path is indicated by reference numeral 60. Thus, in the wind and rain state, the pressure formed by the rainwater of the "U"-shaped cavity 200 and the outdoor pressure will always remain in an equal pressure state, thereby preventing excessive rain from entering the room. When the wind and rain stop, the outdoor air pressure is reduced, so that the pressure of the rainwater formed by the first U-shaped tank body in the room is greater than the outdoor pressure, and the one-way drain valve will automatically open under the action of the pressure difference, so that " The U-shaped first tank body 200 is drained to the outside.

Further, the push-pull device provided by the present invention, when the "U"-shaped groove body 200 is disposed, the height of the first frame 101 can be set to be larger than the height of the first slide rail 102, that is, the first frame 101 is higher than the first frame 101. A slide rail 102. This makes it possible to make the height of the first groove body 200 of the "U" shape larger than the height of the seal between the first slide rail 102 and the first frame frame 201.

In practice, for example, in the event of wind and rain, when the sliding window is closed, that is, the first sliding fan 20 and the second sliding fan 40 are closed, so that the room is closed relative to the outdoor, there must be a pressure difference between the indoor and the outdoor. Therefore, for the sliding window, no matter how tight the seal is, the rain will enter the room under the wind and rain. And as the outdoor wind pressure increases, the rate of rainwater infiltration will also increase. In order to allow the rainwater entering the room to be smoothly discharged outside, the push-pull device 1 provided by the present invention further provides the above-described closed-type equal pressure chamber 300. In the rain and rain, after the rainwater penetrates into the room, it flows along the glass into the "U"-shaped second tank 400. As shown in FIG. 2, since the closed type isostatic chamber 300 is in a closed state, a pressure difference is formed between the indoor and outdoor, and as the rainwater infiltrating into the room gradually increases, the rainwater flowing into the "U"-shaped second tank 400 is caused. The pressure formed is gradually equal to the outdoor pressure, forming an equal pressure. If rainwater penetrates further In the "U"-shaped second tank 400, the water pressure in the "U"-shaped second tank 400 is greater than the outdoor pressure, so that the through holes are provided on the second rail 301 and the third frame 302. The one-way drain valve will be opened and the rain will drain out. Specifically, as shown in FIG. 2, the rainwater in the "U"-shaped second tank 400 is shown to flow out of the outdoor through the second slide 301 and the third bezel 302, as shown by reference numeral 60. Thus, in the wind and rain state, the pressure formed by the rainwater of the "U"-shaped second tank 400 and the outdoor pressure will always remain in an equal pressure state, thereby preventing excessive rain from entering the room. When the wind and rain stop, the outdoor air pressure is reduced, so that the pressure of the rainwater formed by the "U" type second tank 400 in the room is greater than the outdoor pressure, and the one-way drain valve will automatically open under the action of the pressure difference, so that " The U-shaped second tank 400 is drained to the outside.
