Description

Technical Field

[0001] The utility model belongs to the technical field of building ventilation, and in particular relates to a building ventilation and air exchange device. Background Art

[0002] If a building's interior is left without ventilation for extended periods, harmful substances such as carbon dioxide, formaldehyde, ammonia, bacteria, dust mites, and various volatile organic compounds (VOCs) can accumulate in the air. Poor indoor air quality can lead to discomfort, dizziness, fatigue, and even respiratory illnesses. Ventilation removes polluted air and introduces fresh outdoor air, effectively improving indoor air quality and creating a positive indoor environment.

[0003] Most of the existing pipes are fixed structures and rely on the main fan in the machine room for ventilation. As a result, the ventilation effect of pipes that are far away from the main fan is poor. In addition, due to the vibration generated during air supply, some pipes of fixed structures are prone to loosening or even breaking, further affecting the ventilation effect. Utility Model Content
