A smoke maze used for smoke detectors and smoke detectors

Abstract

The invention discloses a smoke inlet labyrinth for a smoke detector and a smoke detector. The smoke inlet labyrinth comprises a base and an upper cover; a cavity for detecting the concentration of smog is arranged between the base and the upper cover; a plurality of baffle plates are arranged at the periphery of the cavity; the baffle plates are uniformly arranged along the circumferential direction of the periphery of the cavity; a smoke inlet channel for allowing external air to enter the cavity is formed between two adjacent baffle plates; the baffle plates comprise a plurality of specially-shaped plates; convex plates for changing smoke inlet effects of the corresponding smoke inlet channels are arranged on the specially-shaped plates; and the convex plates extend into the cavity. Thesmoke inlet labyrinth can enable the smog in the air to enter or flow out of the detector or the labyrinth more easily; and the structures of the multiple baffle plates arranged in the labyrinth, thesmoke inlet effect of the smoke inlet labyrinth is more uniform.

Description

technical field [0001] The invention relates to the field of smoke detection, in particular to a smoke maze used for a smoke detector and smoke detection. Background technique [0002] With the rapid development of the economy, there are more and more application occasions for smoke alarms and independent smoke alarms; however, there are more or less defects in the maze used on the existing smoke alarms: 1. Direction consistency Bad: The ratio of the same concentration of smoke in each direction is close to the limit of 1.6, or the ratio of the same alarm value of multiple alarms in the same direction is relatively large. 2. Different problems such as difficult entry and exit of smoke: when there is smoke, it is difficult to enter the maze due to structural problems and the required alarm is not realized, or the smoke alarm is difficult to recover after the smoke enters the maze and it is difficult to get rid of the alarm. Contents of the invention [0003] The object of ...

[0002] With the rapid development of the economy, there are more and more application occasions for smoke alarms and independent smoke alarms; however, there are more or less defects in the maze used on the existing smoke alarms: 1. Direction consistency Bad: The ratio of the same concentration of smoke in each direction is close to the limit of 1.6, or the ratio of the same alarm value of multiple alarms in the same direction is relatively large

2. Different problems such as difficulty in getting in and out of smoke: when there is smoke, it is difficult to enter the maze due to structural problems and the required alarm is not realized, or the smoke alarm is difficult to recover after the smoke enters the maze and it is difficult to get rid of the alarm.
