[0001] This utility model relates to the technical field of building ventilation devices, and in particular to a building ventilation device. Background Technology

[0002] Building ventilation is divided into natural ventilation and mechanical ventilation. Natural ventilation refers to the direct or purified exhaust of polluted indoor air to the outside, followed by the replenishment of fresh air, thereby maintaining the indoor air environment in accordance with hygiene standards. Currently, most buildings use mechanical ventilation during construction to increase ventilation efficiency. Corresponding ventilation ducts are laid inside the building, and corresponding fans are installed at the air outlets to drive air circulation and accelerate air exchange. Therefore, a building ventilation device is needed.

[0003] Existing building ventilation systems typically have filters installed inside the ventilation ducts to filter solid impurities in the air. When used for an extended period, the filters need to be replaced and removed. However, since the fans are usually fixed in place, the entire unit needs to be disassembled to remove the filters, which is quite troublesome. Utility Model Content
