Description

Technical Field

[0001] The utility model relates to the technical field of buildings, in particular to a building ventilation structure. Background Art

[0002] Ventilation is a basic condition that must be met in residential or office spaces. Only good ventilation can ensure the circulation of air in a building. Ventilation methods are divided into natural and mechanical methods. The natural method relies on the natural flow of air to achieve ventilation, while the mechanical method uses the external force generated by the ventilation structure to improve the ventilation effect.

[0003] The building ventilation structure in the prior art generally includes a filter and a fan. The airflow generated by the fan is used to introduce the external gas into the room, and then the difference in internal and external air pressure is used to discharge the indoor gas to the outside through a one-way valve, thereby achieving the effect of ventilation. The existing mechanism uses a filter to filter the outdoor gas, thereby filtering out impurities in the external air, but the filter itself has to filter dust. The dust will adhere to the filter and block the holes in the filter, thereby affecting the efficiency of the fan in guiding the gas, thereby affecting ventilation. The existing method is to clean the dust manually, which requires disassembling the structure. The process is complicated and often requires professionals. Secondly, in the existing mechanism, in extreme weather, the ventilation device is easily blocked by ice and snow, resulting in ventilation failure, and manual cleaning from the outside is required. Due to the different settings of the ventilation device, the cleaning complexity varies.
