A single-headed bevel gear rod 23 is slidably connected to the middle part of the inner side of the adjusting gear 22, and one end of the rear side of the single-headed bevel gear rod 23 is meshingly connected to a double-headed bevel gear rod 24, and one end of the double-headed bevel gear rod 24 is meshingly connected to one end of the rear side of the fixing rod 26. The rear side of the positioning column block 12 is fixedly connected to the middle part of the front side of the cross fixing plate 15, and the fixing rod 26 is rotatably connected to the middle part of the positioning column block 12. A protective filter screen 16 is fixedly connected to the outer side of the cross fixing plate 15, and a connecting ring groove 17 is provided at the connection between the mounting ring column 2 and the vent housing 1, and one end of the motor 19 is fixedly connected to a supporting hanging plate 18.
[0022] In this embodiment: when adjusting the size of the vent, the electric telescopic rod 20 contracts and drives the bevel gear 21 fixedly connected on one side to be clamped on the driving swivel 11, and then the motor 19 drives the bevel gear 21 to rotate through the electric telescopic rod 20 fixedly connected to the output end, and the rotating bevel gear 21 will drive the driving swivel 11 meshing on one side to rotate, and the rotating driving swivel 11 will drive the helical gear 27 meshing on the inner side to rotate, and the rotating helical gear 27 will drive the fan-shaped valve plate 14 fixedly connected at one end to rotate at a certain angle, thereby opening a hole of a specified size at the position blocked by the fan-shaped valve plate 14, and then the electric telescopic rod 20 pushes the bevel gear 21 away from the outer surface of the driving swivel 11, so that the adjusting gear 22 fixedly connected to the rear side of the bevel gear 21 can be clamped to the rear side of the mounting ring column 2, and then the motor 19 drives the bevel gear 21 through the electric telescopic rod 20 and the bevel gear 21 connected to the electric telescopic rod 20. The adjusting gear 22 fixedly connected to the rear side of the wheel 21 rotates, and the rotating adjusting gear 22 drives the meshing mounting ring column 2 to rotate. At the same time, the rotating adjusting gear 22 drives the single-headed bevel gear rod 23 of the clamp to rotate. The rotating single-headed bevel gear rod 23 drives the fixing rod 26 meshingly connected to one end of the double-headed bevel gear rod 24 through the double-headed bevel gear rod 24 meshingly connected to the rear side to rotate. The rotating fixing rod 26 drives the four fixedly connected fan blades 13 to rotate. The wind force generated by the rotation of the four fan blades 13 pushes the air entering through the fan-shaped valve plate 14 into the filter layer. When the wind speed needs to be adjusted, the fan-shaped valve plate 14 is adjusted to a position parallel to the inclination angle of the fan blades. The rotating mounting ring column 2 drives the fan valve plate 14 adjusted inside to rotate. The wind force generated by the rotation of the fan blades 13 cooperates with each other, which is conducive to promoting the speed at which the air entering through the vent flows into the room.
[0023] When the tooth grooves on the rotating bevel gear 21 are engaged with the driving ring 11, the meshing driving ring 11 is driven to rotate. When the tooth grooves on the bevel gear 21 are separated from the driving ring 11, the driving ring 11 stops rotating, so that the driving ring 11 can generate intermittent rotation. The intermittently rotating driving ring 11 drives the fan-shaped valve plate 14 to generate intermittent rotation.
[0024] Please refer to Figure 1 , Figure 2 and Figure 4A docking ring plate 3 is clamped on one side of the mounting ring column 2, and four clamping plates 4 are evenly distributed on the outside of the docking ring plate 3. A docking tenon 10 is opened in the middle of the clamping plate 4, and a tenon 25 is clamped on the inner side of the docking tenon 10. A protective ring 9 is fixedly connected to the rear side of one end of the tenon 25, and a filter layer clamp ring three 5 is provided on the front side of the protective ring 9. A filter layer clamp ring two 6 is provided on the front side of the filter layer clamp ring three 5, and a filter layer clamp ring one 8 is provided on the front side of the filter layer clamp ring two 6. A filter layer 7 is clamped on the inner sides of the filter layer clamp ring one 8, the filter layer clamp ring two 6 and the filter layer clamp ring three 5.
[0025] In this embodiment: during installation, the docking ring plate 3 is clamped to one side of the mounting ring column 2, and then the position where the docking ring plate 3 contacts the inner wall of the vent housing 1 is fixed by a nut, and then the protective ring 9, the filter layer clamp ring three 5, the filter layer clamp ring two 6 and the filter layer clamp ring one 8 are clamped to the inner side of the clamp plate 4 in sequence, so that the tenons 25 fixedly connected on the protective ring 9, the filter layer clamp ring three 5, the filter layer clamp ring two 6 and the filter layer clamp ring one 8 can be clamped into the docking tenon groove 10 opened in the middle part of the inner surface of the clamp plate 4, thereby fixing the protective ring 9, the filter layer clamp ring three 5. The filter layer clamp ring 2 6 and the filter layer clamp ring 1 8 are fixed on the docking ring plate 3. During ventilation, when the air passes through the protective filter screen 16 and enters the vent, the protective filter screen 16 filters the air for the first time. When the wind force generated by the rotating fan blades 13 pushes the incoming air into the filter layer clamp ring 3 5, the filter layer clamp ring 3 5, the filter layer clamp ring 2 6 and the filter layer 7 of the inner clamp of the filter layer clamp ring 1 8 filter the air for the third time. The filtered air enters the room through the ventilation pipe, which is beneficial to prevent outdoor dust from entering the room through the ventilated air.
