[0026] The door leaf with ventilation function in the utility model is similar to the existing door leaf structure, such as the patent with announcement number CN218563530U discloses a door with ventilation function. The main improvement of the utility model is that the ventilation window 2 is set on the door leaf body 1, and the ventilation window 2 is opened or closed by moving the baffle assembly 5 up and down, and the baffle assembly 5 can also be disassembled for inspection or replacement of the cleaning brush 8. Figures 1 to 8As shown, the door leaf with ventilation function in the utility model, when in use, first pinch the first L-shaped fixing block 507 and the second L-shaped fixing block 508 at the same time, so that the second plate 505 and the third plate 506 move inward along the H-shaped slide groove 502 until the front ends of the first L-shaped fixing block 507 and the second L-shaped fixing block 508 are received in the H-shaped slide groove 502, at this time, the first spring 503 and the second spring 504 are compressed to store energy, and then the first plate 501 is placed in the ventilation window 2, and the first L-shaped fixing block 507 and the second L-shaped fixing block 508 are released. The first spring 503 and the second spring 504 release energy and push the first L-shaped fixing block 507 and the second L-shaped fixing block 508 outward, so that the first L-shaped fixing block 507 and the second L-shaped fixing block 508 slide into the sliding cavity 4, thereby fixing the baffle assembly 5. When the ventilation window 2 needs to be opened, the baffle assembly 5 can be moved upward along the sliding cavity 4, so that the fixing assembly 6 can also be Move upward and pull the pull rod 607 outward so that the slider 605 slides into the circular slide groove 603, and the third spring 604 is compressed. When the front end of the connecting rod 602 is on the surface of the door leaf body 1, the pull rod 607 is released and the baffle assembly 5 continues to move upward. When the slider 605 slides to the first circular hole 7, under the action of the third spring 604, the slider 605 slides into the first circular hole 7, thereby fixing the baffle assembly 5 on the door leaf body 1, so that the ventilation window 2 is opened. To close the ventilation window 2, you only need to pull the pull rod 607 outward and then move the baffle assembly 5 downward. You can also use the cleaning brush 8 to clean the insect-proof net 302 by moving the baffle assembly 5 up and down. When the baffle assembly 5 closes the ventilation window 2, by pinching the first L-shaped fixing block 507 and the second L-shaped fixing block 508 at the same time, the front ends of the first L-shaped fixing block 507 and the second L-shaped fixing block 508 are retracted into the H-shaped slide groove 502, and the baffle assembly 5 can be removed by pulling it outward.

[0027] like Figure 1 or Figure 2 As shown, the ventilation windows 2 are divided into two groups, each group has two ventilation windows, and they are arranged in a linear array in the horizontal and vertical directions.

[0030] Specifically, the support frame 301 changes the ventilation window 2 into several small windows, thereby improving the firmness of the door leaf body 1 and preventing people from putting their hands into the house through the ventilation window 2 to open the lock. The insect-proof net 302 can isolate the insects from the external environment and prevent the insects from entering the room.

[0031] like Figure 3 , Figure 4 Figure 5 or Figure 8 As shown, the baffle assembly 5 includes a first plate 501 arranged in the sliding cavity 4, an H-shaped sliding groove 502 is opened inside the first plate 501, a plurality of first springs 503 are fixedly connected to the left side of the H-shaped sliding groove 502, a plurality of second springs 504 are fixedly connected to the left side of the H-shaped sliding groove 502, the output end of the first spring 503 is fixedly connected to the second plate 505, the output end of the second spring 504 is fixedly connected to the third plate 506, the right side of the second plate 505 is fixedly connected to the first L-shaped fixing block 507, and the right side of the third plate 506 is fixedly connected to the second L-shaped fixing block 508.

[0032] Specifically, pinch the first L-shaped fixing block 507 and the second L-shaped fixing block 508 at the same time, so that the second plate 505 and the third plate 506 move inward along the H-shaped slide groove 502 until the front ends of the first L-shaped fixing block 507 and the second L-shaped fixing block 508 are received in the H-shaped slide groove 502. At this time, the first plate 501 can be placed in the ventilation window 2, and the first L-shaped fixing block 507 and the second L-shaped fixing block 508 can be released, so that the front ends of the first L-shaped fixing block 507 and the second L-shaped fixing block 508 can be slid into the sliding cavity 4, thereby sliding the baffle assembly 5 to the door leaf body 1, and the baffle assembly 5 can be removed by performing the reverse operation.

[0033] like Figure 7 As shown, a cleaning brush 8 is fixedly connected to the inner surface of the first plate 501 .

[0034] Specifically, the baffle assembly 5 can be moved up and down to allow the cleaning brush 8 to clean the anti-insect net 302.

[0035] like Figure 6 or Figure 8 As shown, the fixing assembly 6 includes an L-shaped support rod 601 fixed on the surface of the first plate 501, the upper end of the L-shaped support rod 601 is fixedly connected to a connecting rod 602, a circular slide groove 603 is provided inside the connecting rod 602, a third spring 604 is fixedly connected to the inner wall of the circular slide groove 603, a slider 605 is fixedly connected to the output end of the third spring 604, a second circular hole 606 is provided on the surface of the connecting rod 602, the second circular hole 606 is connected to the circular slide groove 603, a pull rod 607 is slidably connected in the second circular hole 606, and the front end is fixedly connected to the slider 605.

[0036] Specifically, when the ventilation window 2 needs to be opened, the baffle assembly 5 is moved upward along the sliding cavity 4, so that the fixing assembly 6 can also be moved upward, and the pull rod 607 is pulled outward to make the slider 605 slide into the circular sliding groove 603, and the third spring 604 is compressed. When the front end of the connecting rod 602 is on the surface of the door leaf body 1, the pull rod 607 is released, and the baffle assembly 5 continues to be moved upward. When the slider 605 slides to the first circular hole 7, under the action of the third spring 604, the slider 605 slides into the first circular hole 7, thereby fixing the baffle assembly 5 on the door leaf body 1, so that the ventilation window 2 is opened. The baffle assembly 5 can be made to slide down by the opposite operation, thereby closing the ventilation window 2.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
