Description
Technical field
The present invention relates to a kind of fire alarms, belong to field of fire fighting equipment.
Background technology
Economic with society continues to develop, and the continuous improvement of living standard, countless household electrical appliances are come into people's lives,
While the facility that the science and technology that indulges in luxuriousness to one's heart's desire is brought, the awareness of the importance of fire prevention of people gradually fades away people, and the hidden danger moment of fire is adjoint
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 to realize warning function by smoke sensor device, passes through
It the phenomenon that often will appear false alarm, can alarm as smoke sensor device detects smoke from cigarette also.
Invention content
The technical problem to be solved by the present invention is to provide a kind of fire report simple in structure, alarm accuracy rate is high
Alert device.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of fire alarm, including babinet, the body side offer blow vent, are provided in the babinet
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 babinet is cuboid.
The blow vent is located on the side wall of the babinet.
Beneficial effects of the present invention：A kind of fire alarm provided by the invention, existing smoke monitoring is become
Pressure monitoring, alarm accuracy rate are high.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of fire alarm of the present invention.
Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings, and following embodiment is only used for clearly illustrating the present invention
Technical solution, and not intended to limit the protection scope of the present invention.
As shown in Figure 1, a kind of fire alarm, including babinet 1,1 side of babinet offers blow vent 2, in babinet 1
It is provided with cavity 3, controller 8 and electric bell 9,1 outer wall of babinet is provided with warning lamp 10, and 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, pressure is connected with 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
The battery powered to controller 8, warning lamp 10, pressure sensor 7 and electric bell 9 is provided in body 1 or by externally fed
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 3 inside of cavity offers the groove slided up and down for protrusion 8.
The shape of babinet 1 is cuboid.
Blow vent 2 is located on the side wall of babinet 1.
The operation principle of the present invention is that：Since temperature is not high under normal condition, thermal expansion layer will not expand, and pressure passes at this time
Sensor is not under pressure signal, and when a fire, thermal expansion layer expands, and drives movable plate to move upwards, movable plate
With pressure sensor contacts, controller receives the signal of pressure sensor, opens the power switch of electric bell and warning lamp, realizes
The function of alarm.
The above is only a preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
