Abstract

The invention discloses an unpowered ventilation device which comprises a ventilation channel (3), a transmission rod (4), wind catchers (5) and air exchange paddles (6). One end of the transmission rod (4) is connected with the wind catchers (5), and the other end of the transmission rod (4) is connected with the air exchange paddles (6). The air exchange paddles (6) are arranged in the ventilation channel (3), the wind catchers (5) are arranged outside the ventilation channel (3), and the transmission rod (4) is connected with the ventilation channel (3) through a bearing. The unpowered ventilation device is simple in structure and good in wind catching effect.

Description

Technical field [0001] The present invention relates to a new type of non-powered ventilation device, specifically, a new type of non-powered ventilation device that uses natural wind to drive ventilation blades through the rotation of a wind catcher to extract indoor air to achieve the purpose of ventilation. Power ventilation device. Background technique [0002] With the improvement of living standards and quality, more and more attention is paid to the building physical environment closely related to comfort. Due to the ubiquity and increasing of indoor air pollution, strengthening indoor ventilation has attracted more and more attention. Among them, natural ventilation is most popular with people because of its comfortable, energy-saving and natural characteristics. [0003] At present, the conventional unpowered hood uses the blades on the turbine blade shell to capture the wind on the windward side to push the blade shell to rotate. The turbine blade shell generates centri...
