Independent-type smoke sensing detector

Abstract

The invention discloses an independent-type smoke sensing detector. According to the independent-type smoke sensing detector, novel and fine structural design is adopted, so that a shell, a middle buckle and a base can be detachably combined and fixed, and a PCB, a loudspeaker and the middle buckle are detachably combined and fixed; and therefore, the spatial arrangement of the independent-type smoke sensing detector is compact, the internal structure of the independent-type smoke sensing detector is firm, the limiting of components is stable, and assembly production and installation and maintenance are facilitated. A smoke sensing assembly, adopted as an internal core, is of an integrated structure; the PCB, a maze, a receiving tube shielding cover, an infrared emission tube and an infrared receiving tube are connected through surface-mounting processing so as to form an integrated body, and the integrated body is arranged in the middle buckle, so that the detector body of the detector can be assembled; yield is high; production efficiency is high; surface-mounting process difficulty and detector body assembly difficulty are greatly reduced; the internal structure of the independent smoke sensing product is more integrated; the modular production of the independent smoke sensing product is realized; the production efficiency of the independent smoke sensing product is improved; and the structure optimization design and function extension, research and development of the independent smoke sensing product are promoted. The independent-type smoke sensing detector is suitablefor intelligent fire protection.

Description

technical field [0001] The invention relates to the technical field of intelligent fire protection, in particular to an independent smoke detector. Background technique [0002] With the continuous improvement of people's living standards and the rapid development of the economy, various modern household appliances are increasing, and fire accidents that threaten our lives are also increasing. Therefore, the safety problems of residential buildings, office buildings and other places are becoming more and more serious People are paying more and more attention to it. People are equipped with monitoring and alarm devices in order to be able to detect in advance to avoid heavy loss of life and property. [0003] The smoke detector is an extremely important one of many monitoring and alarm devices. The independent smoke detector in the prior art is produced by a photoelectric sensor with a special structural design and an SMD chip processing technology, and has high sensitivity, ...

AI Technical Summary

Problems solved by technology

[0004] In the production process of independent smoke detectors, due to the precision and variety of internal components, its patch production and overall assembly are difficult, which not only limits its own production efficiency, hinders manufacturers from becoming bigger and stronger, but also restricts to a certain extent Structural optimization design and function expansion research and development of independent smoke detector products
