Abstract

The invention relates to a ventilator, in particular to a fireproof thin roof ventilator which comprises mounting frames. An emergency ventilation mechanism is arranged on the mounting frames, the emergency ventilation mechanism comprises a mounting plate fixed between the mounting frames, a transverse plate fixed to the mounting plate through a mounting seat and a top plate fixed to the transverse plate, and a through groove is formed in the mounting frame; and a sliding rail is fixed to the inner wall of the through groove, a moving plate matched with the transverse plate is slidably connected to the sliding rail, and a first driving mechanism used for driving the moving plate is arranged on the mounting plate. According to the fireproof thin roof ventilator in the technical scheme, thedefects that in the prior art, the ventilation quantity cannot be adjusted, and the waterproof performance is poor can be effectively overcome.

Description

technical field [0001] The invention relates to a ventilator, in particular to a fireproof thin roof ventilator. Background technique [0002] Roof ventilator is also called roof natural ventilator, roof natural ventilator, etc. It mainly revolves around the theory of aerodynamic wind carrier type that "when the wind acts on an object, the windward side is the pressure, and the leeward side and the side along the wind direction are the suction". Roof ventilators are usually divided into strip roof ventilators and spherical roof ventilators, among which strip roof ventilators are divided into streamlined roof ventilators and thin roof ventilators. [0003] Ventilation is very important to human health, and poor ventilation will make it difficult for various pollutants to dilute and diffuse. If people stay in this environment for a long time, the damage to the body is self-evident. It is obviously useless to stay indoors for a long time to avoid air pollution from the outside...
