Description

Technical Field

[0001] The utility model relates to the technical field of ventilation equipment, and more specifically, to a ventilation structure for indoor buildings. Background Art

[0002] In architectural design, daily ventilation work is generally completed by windows. Opening windows allows air exchange and circulation between inside and outside. However, when it is windless or hot and humid, the natural air flow is small. In order to ensure good indoor ventilation, ventilation devices are usually used to enhance the air circulation in the building.

[0003] The existing exhaust duct is provided with a filter layer. During use, a lot of dust and debris are attached to the filter layer and the inside of the exhaust duct. The above exhaust duct is only convenient for replacing and cleaning the filter layer, but it is not easy to clean the exhaust duct.

[0004] After searching, a Chinese patent with publication number CN219841621U discloses a ventilation structure for indoor buildings. The filter layer of the utility model can filter and purify the air entering the inside of the pipe from the interface. The purified air enters the room from the air outlet. The swirl air guide plate allows the airflow to diffuse into the house in a swirl form, allowing the clean air to cover a larger area in the room. The second driving member drives the filter layer to move up and down, and the brush cleans the inner wall of the pipe. The cleaned dust enters the annular dust hopper. The staff then cleans the dust in the annular dust hopper to complete the cleaning of the pipe.

[0005] However, when the above ventilation structure is actually used, since the air inlet is usually set at a higher position, dust and debris may accumulate on the surface of the filter of the air inlet. At the same time, after multiple filters filter the air, it is inconvenient to clean the multiple filters and the filters on the air inlet, which affects the ventilation efficiency.
