Description

Technical Field

[0001] The utility model relates to the field of building ventilation, in particular to a ventilation device for building automatic control. Background Art

[0002] At present, a Chinese utility model with the announcement number CN217503895U discloses a ventilation device for building automatic control, including an air duct, a mounting structure, an air inlet unit, an air inlet extension unit, an air outlet unit and a closing plate; the air duct is used to connect the indoor environment of the building with the external environment, so as to discharge the air in the building; the air duct is suspended and installed on the top of the indoor environment of the building through the mounting structure; the air in the building is sucked in through the air inlet unit; the air inlet unit is extended through the air inlet extension unit, so that the corresponding indoor air area of ​​the building can be focused on; the air in the building is discharged through the air outlet unit, and at the same time, foreign matter is prevented from entering the air duct; the air outlet unit is closed by the closing plate when the indoor air of the building is not discharged; air is introduced into the air duct through the air inlet; the air in the air duct is discharged through the air outlet; and the air in the air duct is circulated by the fan;

[0003] Although the existing ventilation device can intercept foreign matter through the filter, there are still other problems during use, such as the inability to adjust the internal ventilation volume. Even if the fan inside the device is in a stopped state, there will be air circulation. In cold weather or when the external air is polluted, it cannot prevent its entry. The applicability is poor, and it does not have the function of removing impurities and self-cleaning. After the device is used for a long time, dust in the air will adhere to the bottom of the filter. However, since the device is at a high place, people below need to use a ladder to contact and clean the filter, which is time-consuming and labor-intensive. In order to solve the above-mentioned problems, we propose a ventilation device for building automatic control. Utility Model Content

[0004] The utility model aims to provide a building automatic control ventilation device, which solves the problem that the existing ventilation device does not have the air volume adjustment function and does not have the impurity removal and self-cleaning function.

[0006] The above technical solution can provide an air volume adjustment function, allowing personnel to block and reduce air circulation in cold weather or when external air is polluted, thereby improving the applicable environment and flexibility of the device. At the same time, it can have a debris removal and self-cleaning function, which is simple and labor-saving to operate, reduces the workload of personnel, and is highly practical.

[0009] The utility model is further configured as follows: a protective cover is bolted to the front of the fixing frame.

[0010] By adopting the above technical solution and providing a protective cover, the second motor can be protected to prevent dust in the air from adhering to it.

[0011] The utility model is further configured that: the surfaces of the fixing frame and the fixing cylinder are coated with anti-corrosion paint.

[0012] By adopting the above technical solution and providing the anti-corrosion coating, the anti-corrosion effect on the surface of the fixing frame and the fixing cylinder can be improved, thereby extending the service life of the fixing frame and the fixing cylinder.

[0016] By adopting the above technical solution, through the provision of the inspection slot and the inspection plate, it is convenient for personnel to install and inspect the components inside the fixed frame.

[0017] The utility model is further configured as follows: the rotating shaft and the baffle are both made of stainless steel.

[0018] By adopting the above technical solution, the rotating shaft and the baffle have the characteristics of high strength, low density and excellent corrosion resistance.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. The utility model fixes the fixing frame to the designated position of the building first, and then starts the second motor after the fixing frame is fixed. After starting, the second motor drives the rotating shaft to rotate, and the rotating shaft drives the baffle to rotate together when rotating. When rotating, the baffle cooperates with the mounting seat to adjust the ventilation volume of the opening in the fixing frame, and can have the function of adjusting the air volume, so that personnel can block and reduce air circulation in cold weather or when the external air is polluted, thereby improving the applicable environment and flexibility of the device;

[0021] 2. The utility model starts the first motor, and after starting, the first motor will drive the second gear and the rotating rod to rotate with the cooperation of the first gear. When the rotating rod rotates, it will drive the brush body to rotate together. Since the cleaning surface of the brush body faces upward and fits with the bottom of the filter screen, the brush body will scrape off the dust and odor at the bottom of the filter screen when rotating, and can have the function of removing impurities and self-cleaning. The operation is simple and labor-saving, which reduces the workload of personnel and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
