Example Embodiment

[0033] The technical solutions in the embodiments of the present invention will be apparent from the drawings in the embodiment of the present invention.

[0034] The embodiment of the present invention is achieved, such as figure 1 The sucking-inhaled firing fire detection device, including:

[0035] The housing member 1 is provided inside an probe chamber;

[0036] The cycle detecting member 2 provided in the housing member 1 extends outside the casing member 1 for inside the air in the outer fire space of the shell member 1, and The inhaled air is recycled.

[0037] In the actual application, the casing member 1 is mounted in a space requiring to detect fires: such as machine room, library, cold storage, distribution box, etc., the cycle detection 2 will inhale the air outside the housing In the probe cavity in the body member 1, the air intake the air in the probe cavity is then recycled, thereby improving the sensitivity and accuracy of the detection, thereby reducing fire ha...

Abstract

The invention relates to an air-breathing smoke-sensing fire detection device, and belongs to the technical field of smoke-sensing detection. The device comprises a shell part which is internally provided with a detection cavity; and a circulating detection part which is arranged in the shell part, has one end extending to the outside of the shell part, and is used for sucking air in the fireproof space outside the shell part into the detection cavity and carrying out circulating detection on the sucked air. Circulating detection is carried out through a particulate matter sensor, the detection is very sensitive and is 1000 times more sensitive than traditional fire detection, and very early fire can be detected; and meanwhile, detection cost performance is high, installation and debugging are convenient, and life and property safety of people can be protected to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of smoke detection, in particular to an aspirating smoke detection device and method. Background technique [0002] Fire refers to the disaster caused by burning out of control in time or space. Among various disasters, fire is one of the main disasters that most frequently and commonly threaten public safety and social development. [0003] In order to prevent fires as much as possible and give timely notification when a fire occurs, which can greatly reduce the damage caused by fire, corresponding fire detection is required. Traditional fire detection devices include ion smoke sensing devices, infrared photoelectric smoke sensing devices, ultraviolet or infrared flame detection devices. [0004] The current fire detection devices still have certain defects. Their common shortcoming is low sensitivity. The sensitivity of point-type infrared photoelectric smoke generally adopts a shading rate of 2% obs / m-2...
