Abstract

The invention relates to the technical field of air exhaust, in particular to a wind-powered exhaust system. The invention solves the problem that the prior exhaust system can not achieve on-time and overall exhaust and ventilation by providing a wind-powered exhaust system capable of preventing exhausted air from being recharged. The wind-powered exhaust system comprises a fixed air passage, an exhaust fan and air outlet, wherein an upper end of the fixed air passage is connected with a rotary air passage, and an air door is arranged at the air outlet. The wind-powered exhaust system has the advantages of no secondary pollution, environmental protection, simple maintenance and reduced labor cost, economization and practicality, effective and complete discharge of dirt air in the air passage, prevention of air-flow recharge, and ensured smooth air discharge and freshness of air.

Description

technical field [0001] The invention relates to the technical field of exhaust, in particular to a pneumatic exhaust system. Background technique [0002] In order to improve the living environment, the buildings are generally equipped with exhaust devices with different specifications. However, the existing exhaust devices have fixed air outlets, resulting in no way to change the direction of the wind. When the wind direction changes, when the exhaust air When the windward face faces the ground and the external wind is strong, it will cause difficulty in exhausting the air, which will easily cause the backflow of the airflow, and the air cannot be updated in time, resulting in poor exhaust, which will block the airflow and affect the exhaust effect, which is not conducive to the people living in it. people's health. Contents of the invention [0003] The present invention aims to solve the problem that the existing exhaust system cannot exhaust and ventilate in a timely ...
