People at one's side, in recent years, fire frequently occurs, and the life and property to people cause huge loss, to the people with
Carry out grave danger.Existing fire alarm generally adds controller by smoke sensor device to realize warning function, passes through
It the phenomenon that often will appear false alarm, will call the police as smoke sensor device detects smoke from cigarette also.
Utility model content
The technical problems to be solved in the utility model is to provide the fire that a kind of structure is simple, alarm accuracy rate is high
Calamity alarm.
In order to solve the above technical problems, the technical solution adopted by the utility model is:
A kind of fire alarm, including cabinet, the body side offer blow vent, are provided in the cabinet
Cavity, controller and electric bell, the cabinet exterior are provided with warning lamp, and thermal expansion layer is provided in the cavity, and the heat is swollen
It is provided with movable plate on swollen layer, pressure sensor, the pressure sensor and institute are connected with below the inside cavity upper surface
It states controller to be connected, the controller is connected with the power switch of the electric bell and warning lamp.
The shape of the cavity is cylinder.
The material of the cavity is stainless steel.
The movable plate side is connected with protrusion, and the inside cavities offer the groove slided up and down for the protrusion.
The shape of the cabinet is cuboid.
The blow vent is located on the side wall of the cabinet.
The utility model has the beneficial effects that a kind of fire alarm provided by the utility model, by existing smog
Monitoring becomes pressure monitoring, and alarm accuracy rate is high.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of fire alarm of the utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawing, following embodiment is only used for clearly illustrating this
The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
As shown in Figure 1, a kind of fire alarm, including cabinet 1,1 side of cabinet offers blow vent 2, in cabinet 1
It is provided with cavity 3, controller 8 and electric bell 9,1 outer wall of cabinet is provided with warning lamp 10, thermal expansion layer 4 is provided in cavity 5, heat
Expanding layer 4 is chosen as polythene material.It is provided with movable plate 5 on thermal expansion layer 4, is connected with pressure below 3 inside upper surface of cavity
Force snesor 7, pressure sensor 7 are connected with controller 8, and controller 8 is connected with the power switch of electric bell 9 and warning lamp 10.Case
It is provided in body 1 to the battery of controller 8, warning lamp 10, pressure sensor 7 and electric bell 9 power supply or by external power supply
Mode.
The shape of cavity 3 is cylinder.
The material of cavity 3 is stainless steel.
5 side of movable plate is connected with protrusion 6, and the groove slided up and down for protrusion 8 is offered on the inside of cavity 3.
The shape of cabinet 1 is cuboid.
Blow vent 2 is located on the side wall of cabinet 1.
The working principle of the utility model are as follows: since temperature is not high under normal condition, thermal expansion layer will not expand, and press at this time
Force snesor is not under pressure signal, and when a fire, thermal expansion layer expands, and movable plate is driven to move upwards, living
Movable plate and pressure sensor contacts, controller receive the signal of pressure sensor, open the power switch of electric bell and warning lamp,
Realize the function of alarm.
The above is only the preferred embodiment of the utility model, it should be pointed out that: for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
