Description

Technical Field

[0001] The utility model relates to the field of fire fighting equipment, in particular to a multifunctional automatic smoke exhaust system. Background Art

[0002] In the field of firefighting equipment, smoke exhaust systems refer to systems used to effectively exhaust smoke and harmful gases when a fire occurs. Smoke exhaust systems play a key role inside buildings, helping firefighters to better fight fires and evacuate people. The construction and use of smoke exhaust systems comply with fire safety standards, can reduce smoke damage and casualties in fires, and improve the efficiency and success rate of fire fighting.

[0003] However, most traditional smoke exhaust systems have relatively simple functions and can only discharge fire smoke. Moreover, most traditional smoke exhaust systems are usually manually or timed controlled, lack intelligent control systems, and cannot automatically exhaust smoke and alarm according to specific circumstances.

[0004] Therefore, those skilled in the art provide a multifunctional automatic smoke exhaust system to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a multifunctional automatic smoke exhaust system is proposed. Compared with most traditional smoke exhaust systems, the smoke exhaust system is provided with a plurality of infrared smoke detectors, which can detect the smoke generated when a fire occurs.

In normal use, the processing control module will control the smoke exhaust fan to rotate at a low speed. By regularly rotating the smoke exhaust fan at a low speed, it can be detected whether the working state of the smoke exhaust system is normal. The low-speed rotating smoke exhaust fan can also circulate and convect the air indoors and outdoors, thereby further improving the safety of the use of the smoke exhaust system.
