Smoke alarm with spraying function

Abstract

The invention relates to the technical field of fire fighting equipment, in particular to a smoke alarm with a spraying function. The smoke alarm comprises an electromagnetic valve, a connecting pipe, a water tank, a main control room, a centrifugal fan, a detection room and an air pipe; the main control chamber is mounted in the mounting groove of the water tank, and the air pipe penetrates out of the middle of the main control chamber, so that equipment damage caused by equipment melting or scorching due to too high indoor temperature in a fire disaster can be effectively avoided; meanwhile, when the temperature sensor detects that the smoke exceeds a preset threshold value, a signal is sent to the controller, the controller controls the centrifugal fan to start and the button to bounce, so that the two electromagnets are powered off, the folded air pipe falls and is opened under the action of gravity, the air pipe can suck smoke at a lower height into the detection chamber, the sensing speed of smoke detection is increased, alarming is advanced, and the centrifugal fan only works when detection is needed, so that resources are effectively saved.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to a smoke alarm with a spray function. Background technique [0002] The smoke alarm is usually installed on the ceiling of the house. When a fire breaks out, the smoke diffuses into the smoke alarm on the ceiling and sends a signal after detecting the smoke. However, due to the poor air circulation of the house, when a fire breaks out in the house, It takes a long time for the smoke to diffuse to the position of the smoke alarm, which reduces the reliability of the smoke alarm to a certain extent and cannot sense the smoke at the first time. At the same time, after the smoke alarm is installed on the ceiling of the house, due to the inconsistent height of the room space, the smoke rising from the fire source on the ground of the house cannot quickly reach the position where the detection sensor seat is located, making the induction effect not ideal, which will lead...

Problems solved by technology

[0002] The smoke alarm is usually installed on the ceiling of the house. When a fire breaks out, the smoke diffuses into the smoke alarm on the ceiling and sends a signal after detecting the smoke. However, due to the poor air circulation of the house, when a fire breaks out in the house, It takes a long time for the smoke to diffuse to the position of the smoke alarm, which reduces the reliability of the smoke alarm to a certain extent and cannot sense the smoke in the first place

At the same time, after the smoke alarm is installed on the ceiling of the house, due to the inconsistent height of the room space, the smoke rising from the fire source on the ground of the house cannot quickly reach the position where the detection sensor seat is located, making the induction effect not ideal, which will lead to detection The induction time is too long, so reasonable smoke alarms should be improved in structure to increase the induction speed and make the alarm earlier

[0003] The smoke alarm is installed on the ceiling of the house, and is usually exposed vertically to the outside. When an indoor fire occurs, it can only be used as an alarm, and it cannot be protected by itself. When the indoor temperature is too high, it will be melted. or scorched, causing damage to the device
