[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 1-5 This utility model provides an embodiment of a sloping roof ventilation and exhaust device, including an outer frame 1. Several sets of adjusting rods 2 are equidistantly installed inside the outer frame 1. First baffles 3 are fixedly connected to the outer side of each adjusting rod 2. An angle adjusting component 5 is provided on the outer side of the adjusting rod 2. The angle adjusting component 5 includes a gear 503 and a rack 504. A movable groove 501 is opened inside the outer frame 1. A servo motor 502 is installed inside the movable groove 501. The gears 503 are equidistantly arranged in the movable groove 501. The rack 504 is installed on the outer side of the gears 503. By controlling the angle of the multiple sets of first baffles 3, natural wind is introduced into the room.

[0025] This device, through the setting of angle adjustment component 5, solves the drawbacks of poor air circulation between the inside and outside of the house after installation, poor ventilation performance inside the house, and inability to adjust according to inclement weather.

[0026] Furthermore, the first baffle 3 is arc-shaped, and its bottom is attached to and overlaps with the top of another set of first baffles 3. This design of multiple sets of first baffles 3 can guide the airflow while reducing wind resistance and improving the safety of the device. Figure 2 As shown, this structure is used to utilize the shape features of the first baffle 3, combined with the laying pattern of the tiles, so that when rainwater falls on the surface of the first baffle 3, it falls through the curvature of the first baffle 3, preventing it from falling into the interior of the outer frame 1, thus enhancing the waterproof effect.

[0027] Furthermore, the inner wall of gear 503 is fixedly connected to adjusting rod 2, rack 504 is movably sleeved on each set of gears 503, and the output end of servo motor 502 is fixedly connected to gear 503, with gear 503 and rack 504 meshing with each other. Figure 4As shown, this structure is used to drive the gear 503 to rotate by starting the servo motor 502. The gear 503 meshes with the rack 504, so that multiple sets of gears 503 rotate synchronously, thereby causing the adjusting rod 2 to drive the first baffle 3 to rotate. The arc shape of the first baffle 3 is used to introduce natural wind into the room, so that the air in the room can circulate.

[0028] Furthermore, a retaining ring 6 is installed inside the outer frame 1 at a position corresponding to the adjusting rod 2. Several sets of ball bearings 7 are rotatably mounted on the inner wall of the retaining ring 6, and the adjusting rod 2 passes through the retaining ring 6. Figure 5 As shown, this structure is used to reduce the friction between the adjusting rod 2 and the fixed ring 6 and the ball 7, so that the adjusting rod 2 can drive the first baffle 3 to rotate stably.

[0029] Furthermore, a second baffle 8 is fixedly connected to the inner wall of the outer frame 1, and the second baffle 8 is located between the contact positions of the two sets of first baffles 3. Figure 3 As shown, this structure is used to improve the dustproof effect of the device by setting the second baffle 8.

[0030] Furthermore, the second baffle 8 has an inverted L-shaped cross-section, and its bottom is located above the adjusting rod 2, which can limit the rotation angle of the first baffle 3. Figure 3 As shown, this structure is used to allow rainwater to fall into the second baffle 8, and then be guided by the second baffle 8 to another set of first baffles 3, so that the rainwater can be discharged.

[0031] Furthermore, an exhaust fan 4 is installed inside the outer frame 1, and the exhaust fan 4 and servo motor 502 are connected to an external PLC controller via wires. For example... Figure 2 and Figure 4 As shown, this structure is used to control the start of exhaust fan 4 and servo motor 502 through a PLC controller, and to start exhaust fan 4 to exhaust air.

[0032] Working principle: When using, such as Figure 1 and Figure 4 As shown, based on weather conditions, the servo motor 502 is started via the PLC controller, driving the gear 503 to rotate. The gear 503 meshes with the rack 504, causing multiple sets of gears 503 to rotate synchronously. This, in turn, causes the adjusting rod 2 to rotate the first baffle 3. The arc shape of the first baffle 3 guides natural wind into the room, improving air circulation. Figure 2 and Figure 3As shown, the exhaust fan 4 can also be activated to exhaust air. When it rains, the first baffle 3 is closed. When rainwater falls on the surface of the first baffle 3, it falls through the arc of the first baffle 3, preventing it from falling into the interior of the outer frame 1 and enhancing the waterproof effect. The rainwater falls into the second baffle 8 and is then guided by the second baffle 8 to another set of first baffles 3, so that the rainwater is discharged. The above is the complete working principle of this utility model.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
