Embodiment Construction

[0021] As mentioned earlier, this wind driven roof ventilator can be used to create positive and negative air pressures to draw in air and expel air. The wind-driven roof ventilator includes an aerodynamically shaped symmetrical curved cap, so that when the wind flows through the back of the symmetrical cap, a negative pressure area will be generated at the front opening of the symmetrical cap, thereby exhausting the gas in the indoor place; The wind flows through the front opening of the symmetrical cap, and the symmetrical cap will guide the air, thereby realizing the inhalation of air. Therefore, the present wind-driven roof ventilator can generate positive and negative air pressure without external power supply, fan and / or turbine equipment. The direction change of the symmetrical cap relative to the wind force can be controlled by the directional tail, see below for details.

[0022] Such as figure 1 As shown, the wind-driven roof ventilator includes a symmetrical cap a...

Abstract

A wind-powered rooftop ventilator that can create both positive and negative pressures to enable the exhaust and intake of air is described. The wind-powered rooftop ventilator includes a symmetrical cap that is aerodynamically shaped such that, when wind flows against the back of the symmetrical cap, a negative pressure area is created at the front opening of the symmetrical cap, thereby enabling the exhaust of air from an indoor area. When wind flows against the front opening of the symmetrical cap, the wind is captured by the symmetrical cap, thereby enabling the intake of air into an indoor area. As such, the wind-powered rooftop ventilator can create both positive and negative pressures without use of an external power source, fan, and / or worm gear.

Description

technical field [0001] The present invention relates to ventilators, especially roof wind-driven ventilators capable of generating positive and negative air pressures. Background technique [0002] Common roof ventilators are mostly used to exhaust indoor places, such as bathrooms, kitchens, and industrial plants, to generate heat, bad gases, and turbid gases to promote air circulation. This air circulation does a good job of removing built-up moisture, which prevents structural decay and bacterial growth. Common roof vents are not pretty and are chosen as a roost by birds and insects. In addition, the design height of common roof ventilators is too high, and the structure is multi-piece, which is difficult to install and cannot adapt to different roof slopes. Also, roof ventilators must be of strong construction to withstand the stresses of transport and operation. [0003] Common roof ventilators can be divided into active and passive types. Active roof ventilators can...
