When the sliding sash 2 is closed, the guide plate 5 on the sliding sash 2 and the guide plate 5 on the fixed bracket 9 overlap, so that the side of the sliding sash 2 is sealed with the sealing strip 10. The guide plate 5 is generally S-shaped or Z-shaped. When the sliding sash 2 moves, the guide plate 5 on the sliding sash 2 contacts and squeezes the guide plate 5 on the fixed bracket 9, causing the sliding sash 2 to move to the side and seal with the sealing strip 10.

[0038] The rear end of the guide plate 5 is provided with a screw hole, and the guide plate 5 is installed on the side of the push-pull fan 2 or on the fixed plate 9 by screws.

[0039] The guide wheel 8 is used to guide the sliding sash 2 to move toward the side of the window frame 1 with the sealing strip 10. The guide piece 5 is used to fix the position of the sliding sash 2 when it is closed, ensuring that the sliding sash 2 always maintains a tight fit with the sealing strip 10.

[0040] like Figures 4-6 As shown, based on the above embodiment, a further optimization is made: the upper and lower ends of the sliding fan 2 are provided with guide wheel devices 4 to prevent the sliding fan 2 from rubbing against the side wall of the window frame 1. Two guide wheel devices 4 are respectively provided at the upper and lower ends of the sliding fan 2.

[0041] like Figures 4-6As shown, based on the above embodiment, further optimization is made: the guide wheel device 4 includes a guide wheel base 46 mounted on the push-pull fan, a guide wheel frame 41 mounted on the guide wheel base 46, and guide wheel bodies 42 mounted on both sides of the guide wheel frame 41; one guide wheel body 42 is fixedly mounted, and the other guide wheel body 42 is mounted on a guide wheel movable seat 43, the guide wheel movable seat 43 is movably mounted on a mounting shaft 44, and a spring 45 is provided on the mounting shaft 44 to abut against the guide wheel movable seat 43.
