Description

A household photoelectric smoke detector

technical field

The utility model relates to the technical field of detectors, in particular to a household photoelectric smoke detector.

Background technique

Photoelectric smoke detector is a device for detecting smoke in fire alarm equipment. Its function is to sense the smoke in the surrounding environment and send out an alarm signal when the smoke reaches a certain concentration to prevent fires. The key part of the photoelectric smoke detector is the maze used to detect smoke. The maze is generally composed of two parts: the labyrinth seat and the upper cover of the maze. The photoelectric smoke detector is also a point detector. It uses the smoke generated during a fire to change the light It was developed based on the basic property of propagation characteristics. According to the absorption and scattering of light by smoke particles. Photoelectric smoke detectors are divided into two types: shading type and astigmatism type. The general point type photoelectric smoke detector belongs to the astigmatism type, and the linear beam detector is the shading type. At present, most of the photoelectric smoke detector mazes on the market are too compact, considering space saving and other issues, resulting in the size of the maze. Too small, there is not enough space to design the labyrinth loop structure or the loop is too simple, or even cancel the loop structure and replace it with a filter. Such structures will greatly reduce the dustproof performance of the labyrinth and the residence time of smoke in the cavity, which is not conducive to The receiving device collects data, which greatly affects the performance and stability of the detector.

However, the existing smoke detectors require a certain inclined position during operation, so the reflection area of the smoke is greatly reduced, and then the sensitivity of the detector body is reduced. When the smoke rises and enters the interior of the detector body, it takes a long time , so that the time from the fire to the alarm signal is longer, which greatly affects people's property losses. Since the detector body is exposed to the air for a long time, the air will enter the detector body through the smoke inlet. , thus causing the detector body to fail, so people will clean it, which brings great inconvenience to users.

Therefore, how to design a household photoelectric smoke detector has become a problem to be solved at present.
