Multifunctional smoking pavilion with micro-negative pressure smoke control system

Abstract

This invention discloses a multifunctional smoking pavilion with a micro-negative pressure smoke control system, comprising a pavilion body defining a smoking space; an anteroom located between the smoking space and the external environment, the anteroom having an automatic sliding door; at least one air inlet located at the lower part of the pavilion body; a filter module located at the upper part of the pavilion body and connected to at least one exhaust port; at least one exhaust device connected to the exhaust port; a differential pressure sensor detecting the pressure difference value within the smoking space relative to the external environment; and a control module adjusting the operating parameters of the exhaust device based on the comparison result of the pressure difference value with a preset pressure difference range to stably maintain a micro-negative pressure. Through anteroom isolation, automatic sliding door, bottom-inlet and top-outlet directional flow field, and differential pressure feedback control, it effectively prevents smoke from escaping and integrates multi-layer filtration purification, air quality monitoring, and smart network monitoring functions.
