Description

Technical Field

[0001] This application relates to the technical field of building ventilation, and more particularly, to a building ventilation structure. Background Art

[0058] The ventilation plates 20 are provided with two and are symmetrically located at the ends rotatably connected to the air duct 11. When the two ventilation plates 20 are in the vertical state, one ends of the two ventilation plates 20 are in smooth contact with each other and close the end of the air duct 11. The slider 26 is slidably connected to the inner wall of the ventilation cavity 12, the fixed block 31 is fixedly connected to the side wall of the slider 26, and the cleaning roller 34 is installed on the fixed block 31.

[0059] In order to adjust the inclination angle of the ventilation plates 20, an adjusting member is further provided, and the adjusting member includes: a protective housing 14, an adjusting shaft 21, a belt pulley 23, a belt 24, and an adjusting motor 22.

[0060] The protective housing 14 is fixedly connected to the outer wall of the air duct 11. There are two adjusting shafts 21 which are respectively fixedly connected to the end walls of the two ventilation plates 20. The two adjusting shafts 21 respectively extend into the protective housing 14 and are rotatably connected to the protective housing 14. There are two belt pulleys 23 which are respectively fixedly connected to the two adjusting shafts 21. The belt 24 is tightly sleeved on the two belt pulleys 23. The belt pulley 23 is provided with first teeth, and the belt 24 is provided with a plurality of second teeth meshing with the first teeth at equal intervals. The adjusting motor 22 is fixedly connected to the inside of the protective housing 14, and the output rotating shaft of the adjusting motor 22 is fixedly connected to one of the adjusting shafts 21.

[0061] In order to drive the slider 26 to move and the cleaning roller 34 to rotate, a driving member is further provided, and the driving member includes: a rack 25, a driving motor 27, a driving shaft 28, a driving gear 29, a first bevel gear 30, a connecting shaft 32, and a second bevel gear 33.

[0062] The rack 25 is fixedly connected to the side wall of the ventilation cavity 12. The rack 25 penetrates through the slider 26 and the slider 26 is in sliding contact with the rack 25 relatively. The driving motor 27 is fixedly connected to the side wall of the slider 26. The driving shaft 28 is fixedly connected to the output rotating shaft of the driving motor 27. The driving gear 29 is fixedly connected to the driving shaft 28 and meshes with the rack 25. The first bevel gear 30 is fixedly connected to one end of the driving shaft 28. The connecting shaft 32 is rotatably connected to the fixed block 31. The connecting shaft 32 is fixedly connected to the cleaning roller 34. The second bevel gear 33 is fixedly connected to the connecting shaft 32. The second bevel gear 33 meshes with the first bevel gear 30.

[0063] Working or installation process:

[0064] When it is necessary to adjust the air intake volume of the air inlet of the ventilation cavity 12, the adjustment motor 22 is started. The output rotating shaft of the adjustment motor 22 drives one of the adjustment shafts 21 to rotate. The adjustment shaft 21 drives the pulley 23 located on the adjustment shaft 21 to rotate. The pulley 23 drives another pulley 23 to rotate through the belt 24, and the other pulley 23 drives another adjustment shaft 21 to rotate. The two adjustment shafts 21 synchronously drive the two ventilation plates 20 to rotate. The ventilation plates 20 rotate around the axis of their own adjustment shafts 21 and tilt, so that the end walls of the two ventilation plates 20 no longer contact smoothly. The ventilation plates 20 rotate and tilt, and the ventilation plates 20 no longer close the ventilation cavity 12. When the ventilation plates 20 rotate and tilt to an appropriate angle, the adjustment motor 22 stops working and activates the self-locking function, so that the adjustment shaft 21 of the output rotating shaft of the adjustment motor 22 cannot rotate; by adjusting the tilt angle of the ventilation plates 20, the air intake volume entering the ventilation cavity 12 is adjusted; and during the process of the ventilation plates 20 rotating and tilting, a part of the ventilation plates 20 extends outside the end of the air duct 11 and blocks the air inlet of the ventilation cavity 12, thus playing a rain-proof function and preventing rainwater from splashing into the ventilation cavity 12 from the air inlet of the ventilation cavity 12;

[0065] During the ventilation of the building, the fan 13 is started, and the filter plate 18 filters the air entering the ventilation cavity 12. When the filter plate 18 is used for a long time, a large amount of dust adheres to the filter plate 18, resulting in a reduction in the filtering effect of the filter plate 18, and the filter plate 18 needs to be cleaned; at this time, the driving motor 27 is started. The output rotating shaft of the driving motor 27 drives the driving shaft 28 to rotate. The driving shaft 28 drives the driving gear 29 and the first bevel gear 30 to rotate. The driving gear 29 drives the slider 26 to move along the extension direction of the rack 25 through meshing with the rack 25. The slider 26 drives the fixed block 31 to move synchronously, and the fixed block 31 drives the connecting shaft 32 to move synchronously; during the rotation of the first bevel gear 30, it drives the second bevel gear 33 to rotate through meshing with the second bevel gear 33. The second bevel gear 33 drives the connecting shaft 32 to rotate, and the connecting shaft 32 drives the cleaning roller 34 to rotate, so that the cleaning roller 34 rotates around the axis of its own connecting shaft 32 and moves synchronously from top to bottom following the slider 26. The cleaning roller 34 brushes the surface of the filter plate 18, thereby brushing off the dust adhering to the surface of the filter plate 18. The dust brushed off by the cleaning roller 34 falls downward and enters the dropping groove 19, and the dust passes through the dropping groove 19 and finally drops into the collection box 16.

[0066] When the cleaning roller 34 moves from top to bottom until it moves below the filter plate 18, the driving motor 27 starts in the reverse direction. The output rotating shaft of the driving motor 27 drives the driving shaft 28 to move in the reverse direction, so that the slider 26 moves above the filter plate 18 again.

[0067] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) disclosed in the embodiments of the present disclosure that have similar functions.
