Abstract
The utility model discloses a smoke alarm device, including smoke transducer and audible -visual annunciator, still include air exhauster, bellows and controller, be equipped with a grid in the bellows, the grid divide into air inlet side and air -out side with bellows, the air inlet side of bellows is equipped with the air intake, and the air -out side of bellows is equipped with the air outlet, the air outlet and the air exhauster of bellows are close to the middle part of air inlet side one side through air -out union coupling, smoke transducer dress at the grid, the air outlet of bellows passes through the space that the air -supply line intercommunication was detected, and smoke transducer and audible -visual annunciator are connected with the controller electricity, passes through controller drive audible -visual annunciator when smoke transducer detects smoke signal and reports to the police, the utility model discloses it detects and reports to the police to carry out smog to depressurized environment.
Description
Technical field
This utility model is related to smoke alarm unit.
Background technology
Laboratory or factory in some subnormal ambients, air-flow therein from installation gas channel at flow away,
Once the generation condition of a fire, the ashes that it produces can first flow away from gas channel, is difficult to be installed in top in the initial period of the condition of a fire
The smoke alarm of routine capture the signal of the condition of a fire, miss the Best Times of fire fighting, lead to larger infringement.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of smoke alarm unit, and it carries out cigarette for subnormal ambient
Mist detection and warning.
For reaching above-mentioned purpose, the technical solution of the utility model is: a kind of smoke alarm unit, including Smoke Sensor
And audible-visual annunciator, also include air exhauster, bellows and controller；It is provided with a grid, bellows are divided into inlet side by grid in bellows
And air side；The inlet side of bellows is provided with air inlet, and the air side of bellows is provided with air outlet；The air outlet of bellows is led to air exhauster
Cross discharge pipe to connect, Smoke Sensor is contained in the middle part near inlet side one side for the grid；The air outlet of bellows is by blast pipe even
Logical detected space, Smoke Sensor and audible-visual annunciator are electrically connected with the controller, and Smoke Sensor detects smoke signal
When by controller drive audible-visual annunciator report to the police.
Improve further, the inlet side of described bellows is provided with multiple air inlets, each air inlet is connected with a blast pipe
Connect, multi-point monitoring can be carried out.
Improve further, described bellows are square or cylindrical.
Improve further, described controller is plc.
Improve further, blast pipe connects a flaring air intake part away from one end of bellows, facilitates air intake.
This utility model is provided with a grid in bellows, and bellows are divided into inlet side and air side by grid；The air intake of bellows
Side is provided with air inlet, and the air side of bellows is provided with air outlet；The air outlet of bellows is connected by discharge pipe with air exhauster, and smog passes
Sensor is contained in the middle part near inlet side one side for the grid；The air outlet of bellows is by the detected space of blast pipe connection, this reality
With new blast pipe multi-point monitoring, once there being the condition of a fire to occur, in the presence of air exhauster, smog quickly enters bellows, and smog passes
After sensor senses smog, Smoke Sensor detects and drives audible-visual annunciator to report to the police by controller during smoke signal, this reality
With the fire safety evaluating situation in monitoring place under the new subnormal ambient in laboratory or Factory Building etc., find fire to shortening
Time, fire extinguishing early has important effect.
Brief description
Fig. 1 is this utility model structural representation.
Specific embodiment
With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
Shown in Fig. 1, a kind of smoke alarm unit, including Smoke Sensor 1, audible-visual annunciator 2, air exhauster 3, bellows 4 and
Controller 5, bellows 4 can be square or cylindrical, and described controller 5 is plc.It is provided with a grid 41, grid 41 will in bellows 4
Bellows 4 are divided into inlet side and air side；The inlet side of bellows 4 is provided with multiple air inlets 42, each air inlet 42 and one
Blast pipe 6 is connected, and blast pipe 6 connects a flaring air intake part 61 away from one end of bellows 4.The air side of bellows 4 sets
There is air outlet 43, the air outlet 43 of bellows 4 is connected by discharge pipe 7 with air exhauster 3, and it is close that Smoke Sensor 1 is contained in grid 41
The middle part of inlet side one side；The air outlet 43 of bellows 4 passes through detected space, Smoke Sensor 1 and the acousto-optic of blast pipe 6 connection
Alarm 2 is electrically connected with controller 5, and Smoke Sensor 1 detects and drives audible-visual annunciator 2 by controller 5 during smoke signal
Report to the police, remind the appearance of people's condition of a fire, people's discovery condition of a fire early can be made, reduce property loss, protect life security.
The above is only one preferred embodiment of this utility model, those skilled in the art presses what claim work was equal to
Change the protection domain both falling within this case.
