Description

technical field [0001] The invention relates to the field of photovoltaic solar energy, in particular to a combined smoke exhaust air duct device for preventing smoke backflow. Background technique [0002] Existing manual craft production has thick walls and heavy weight, which is not conducive to transportation and installation, while manual production requires high labor intensity, uneven product quality, negative pressure or static pressure at the air inlet is reduced; open the kitchen to absorb oil In the case of a hood or exhaust fan, a jet is generated at the air inlet to form a negative pressure or reduce the static pressure in the pipe. Effectively improves the exhaust gas volume and prevents the backflow of the flue gas. Contents of the invention [0003] In view of the above problems, the technical problem to be solved by the present invention is to provide a simple in structure, economical and durable combined smoke exhaust duct device for preventing smoke bac...
