[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 A window and door ventilation device includes a window frame 1, an outer frame 2 fixedly mounted on the front of the window frame 1, protective shells 3 fixedly mounted on both sides of the outer wall of the outer frame 2, a waterproof motor 12 fixedly mounted on the inner wall of the protective shell 3, a lead screw 13 fixedly mounted on the output shaft of the waterproof motor 12, a movable frame 4 provided on the inner wall of the outer frame 2, a docking groove 17 provided at both ends of the movable frame 4, a louver 5 rotatably connected to the inner wall of the movable frame 4, a rotating groove 14 provided on the outer wall of the louver 5, a connecting rod 15 rotatably connected to the inner wall of the rotating groove 14, a strip electromagnet 7 fixedly mounted on the bottom of the inner wall of the movable frame 4, a magnetic strip 6 fixedly mounted on the bottom of the louver 5, a guide rail 11 fixedly mounted on the inner wall of the outer frame 2, a glass window 10 slidably connected to the inner wall of the guide rail 11, a temperature sensor 8 and a controller 9 fixedly mounted on the back of the window frame 1, and a tension spring 16 provided on the top of the inner wall of the movable frame 4.

[0025] In the above structure, the window frame 1, outer frame 2, protective shell 3, movable frame 4, louver 5, magnetic strip 6, strip electromagnet 7, temperature sensor 8, and controller 9 are configured so that after installation, the device can be installed by removing one glass window 10 and then ventilating the room by rotating the louver 5. After ventilation, the user does not need to move the glass window 10 back; simply de-energizing the strip electromagnet 7 will reset the louver 5 to seal the window. This reduces the number of times the user moves the glass window 10, reduces wear and tear on the glass window 10 and guide rail 11, and achieves energy saving. Furthermore, the user can adjust the indoor lighting level by rotating the louver 5, thereby improving the practicality of the device.

[0026] In a preferred embodiment, the end of the tension spring 16 is connected to the top of the louver 5, and there are several louver 5s, all of which are connected to each other by a connecting rod 15.

[0027] In the above structure, by setting several louvered fan structures 5, the user can complete the sealing operation of the window by adjusting the angle of the louvered fan 5 during use. This allows the user to close the glass window 10 without moving it, whether it is raining or when it is necessary to close the glass window 10, thereby reducing the number of times the glass window 10 is moved and reducing wear and tear.

[0028] In a preferred embodiment, grooves are provided on the inner walls of both ends of the outer frame 2, and the inner walls of the grooves at both ends are slidably connected to the two ends of the movable frame 4.

[0029] In the above structure, the groove structure allows the sliding frame 4 to slide along the inner wall of the groove during operation, which is achieved by using the docking groove 17 on the sliding frame 4. This makes it easier for the user to adjust the position of the two sliding frames 4, and thus facilitates the user to fully open the window for ventilation, thereby improving the automation of the device.

[0030] In a preferred embodiment, the outer wall of the movable frame 4 has a circular hole, and the inner wall of the circular hole is threadedly connected to the outer wall of the lead screw 13.

[0031] In the above structure, the circular hole structure allows the movable frame 4 to slide along the inner wall of the groove when the lead screw 13 rotates under the drive of the output shaft of the waterproof motor 12, thereby ensuring that the movable frame 4 can move automatically, thus ensuring the normal use of the device and improving the flexibility of the movable frame 4.

[0032] In a preferred embodiment, there are two movable frames 4, which are slidably connected to each other. After installation, the movable frames 4 face the outside, and the glass window 10 faces the inside.

[0033] In the above structure, the outdoor orientation of the movable frame 4 is used to isolate rainwater and sunlight from the outside, making it easy for users to adjust the angle of the louver 5 according to their own needs, meeting the ventilation and lighting requirements of the indoor environment, and also making it easy for users to operate, further improving the practicality of the device.

[0034] In a preferred embodiment, the controller 9 is electrically connected to the temperature sensor 8 and the strip electromagnet 7, respectively, and the strip electromagnet 7 is attracted to the magnetic strip 6 when energized.

[0035] In the above structure, the user can adjust the angle of the louvered fan 5 by switching the magnetic strip 6 and the bar electromagnet 7 on and off, without the need for manual operation. This makes the device easy to operate and further improves its automation.

[0036] In a preferred embodiment, a pressure sensing strip is adhered to the outer wall of the louvered fan 5, and the pressure sensing strip is electrically connected to the controller 9.

[0037] In the above structure, the pressure sensing strip structure is impacted when it is windy or rainy, thus ensuring that the bar electromagnet 7 is always de-energized. This keeps the opening window sealed, preventing rainwater from entering the room and ensuring the rainproof effect of the device.

[0038] In a preferred embodiment, there are two lead screws 13, and both lead screws 13 are symmetrically distributed along the inner wall of the outer frame 2. The waterproof motor 12 is electrically connected to the controller 9.

[0039] In the above structure, the waterproof motor 12 allows the user to operate the waterproof motor 12 via the controller 9 to adjust the position of the movable frame 4, thereby facilitating the user to move the movable frame 4 corresponding to the open window, increasing the area connecting the indoor and outdoor spaces, and thus improving the flexibility of the movable frame 4 and the ventilation effect between the indoor and outdoor spaces.

[0040] Working principle: After the user completes the installation of the device, when the indoor temperature is low and lighting is needed, the user can energize the bar electromagnet 7 to make the magnetic strip 6 and the bar electromagnet 7 attract each other, causing the outward-facing end of the louver 5 to rotate upward, thus creating a gap to allow sunlight to enter the room, making it convenient for the user to adjust the lighting. When ventilation is needed, the user can complete the ventilation operation by following the same steps. Alternatively, the user can operate the waterproof motor 12 through the controller 9 to move the movable frame 4 corresponding to the window, thereby increasing the connection area between the indoor and outdoor environments, thus improving the automation and ventilation effect of the device. During use, the user does not need to reset the moved glass window 10; the louver 5 can be reset to complete the sealing operation, thus ensuring that the device can prevent rain in rainy weather, reducing the number of times the user moves the glass window 10, and thus reducing wear and tear.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
