The present invention relates to a diversion venting apparatus, and more particularly to a diversion venting apparatus mounted on a roof of a factory that directs airflow to force convection between the indoor and outdoor air.

At present, most of the large-scale factories, such as processing plants and warehouses, which are built and used by the industry, are covered with iron sheets, which makes it difficult for the interior of the plant to form a bad environment of high temperature and sultry heat due to the lack of air circulation. In order to allow the air inside the plant to circulate to avoid the accumulation of hot gas at the top of the plant, a common solution is to add a diversion venting device at the vents reserved on the roof of the plant.

The prior art diversion and exhaust device mainly uses a fan to discharge the hot air in the plant to the outside, so that the air inside and outside the plant can be convected, thereby achieving the purpose and effect of cooling. However, in addition to the need to purchase the fan, the fan needs electric drive in the future. Therefore, under long-term use, the electricity bill will be a small expense; and when the day is not good, the fan cannot be used for wind and rain outside the factory. Produce a blocking effect. Therefore, the prior art diversion and exhaust equipment still needs further improvement.
