[0005] A blocking block, wherein the blocking block is fixed on the inner top wall of the window frame, and the blocking block is arranged to abut against the uppermost louver;

[0006] A movable block, wherein the movable block is movably inserted into the lower side wall of the window frame, and after the upper side of the movable block passes through the lower inner wall of the window frame, it is set to abut against the lowermost louver, and a plurality of abutment springs are fixed at equal intervals on the lower side wall of the movable block, and the abutment springs are embedded and fixed in the lower side wall of the window frame;

[0007] There are several worm wheels, and they are sleeved and fixed on the shafts on one side of several shutter blades in a one-to-one correspondence. A worm is meshed on one side of the worm wheel. Several worms are connected by a linkage rod, and the linkage rod is screwed into the window frame through a bearing;

[0010] Through the above technical scheme, the rear side of the window frame is inserted into the vent, and the fixed frame is fixed on the side of the vent. When ventilation is required, the driving motor is used to drive the linkage rod to rotate, and the linkage rod drives the worm gear to rotate through the worm, and the worm gear drives the louver to rotate through the shaft rod on the louver until the louver is in a parallel state. At this time, the louver pushes the sealing mechanism, so that the window frame is in a ventilated state. When the louver needs to be closed, the driving motor is started in reverse, and the driving motor drives the linkage rod to rotate in the opposite direction, so that the adjacent louvers collide with each other, and the lowermost louver pushes the movable block downward, thereby ensuring that the movable block conflicts with the lowermost louver to achieve a sealing effect, and the louver releases the sealing mechanism, and the sealing mechanism conflicts with the louver, thereby further achieving a sealing effect.

[0019] Through the above technical solution, when the louver rotates, the sealing ring and the sealing frame are pushed to move, so that the reset spring is compressed, so that the window frame is in an open state; when the louver rotates to a vertical state, the reset spring drives the sealing frame to move to one side of the louver until the sealing ring and the sealing plate contact the louver; at this time, the sealing ring on the sealing frame blocks the gap between the louver and the inner wall of the window frame, and the sealing plate blocks the gap between the two adjacent louvers, thereby improving the sealing performance.

[0020] As a further improvement of the utility model, a telescopic rod is provided inside the reset spring, and the two ends of the telescopic rod are respectively fixed on the inner wall of the slide groove and the side wall of the sealing frame;

[0021] Through the above technical solution, guidance can be provided for the return spring during its extension and retraction, thereby increasing the service life of the return spring and preventing it from bending.

[0036] The sealing mechanism 11 is arranged inside the window frame 2 , and the sealing mechanism 11 is matched with the louver 3 .

[0037] Embodiment 2:

[0038] See also Figure 2 As shown, based on Example 1, the sealing mechanism 11 includes:

[0039] A sealing frame 11-1, wherein the sealing frame 11-1 is arranged in the window frame 2, and the surrounding walls of the sealing frame 11-1 are movably embedded in the slide grooves on the inner peripheral wall of the window frame 2, and a sealing ring 11-2 is glued and fixed on the front side wall of the sealing frame 11-1, and the sealing ring 11-2 abuts against the louver 3 and the slide grooves on the surrounding walls of the window frame 2;

[0040] The reset spring 11-3 is a plurality of reset springs 11-3, which are equally and equidistantly embedded and welded in the slide grooves of the four walls of the window frame 2, and the front end of the reset spring 11-3 is fixed on the sealing frame 11-1; a telescopic rod 14 is provided inside the reset spring 11-3, and the two ends of the telescopic rod 14 are respectively fixed on the inner wall of the slide groove and the side wall of the sealing frame 11-1, which can provide guidance for the reset spring 11-3 during its expansion and contraction, thereby increasing the service life of the reset spring 11-3 and preventing it from bending;
