Background technology
With society and expanding economy, wealth increasingly increases, and fire is to the mankind, society and the damaging range for causing naturally Constantly expand, it not only damages material property, causes the confusion of civil order, also direct life-threatening safety, the heart for giving people Spirit causes greatly injury;Fire once occur, it is easy to occur putting out a fire to save life and property not in time, fire distinguisher lack and people on the scene lose in alarm Arrange, the unfavorable factor such as slow of escaping, ultimately result in great life and property loss;And good monitoring system and timely alarming machine System can substantially reduce the injures and deaths of personnel, and fire-alarm is developed, fire-alarm to meet this demand Effective alarm can be made for fire, reduce the injures and deaths and property loss of personnel, be one of the important means for preventing fire;But It is complicated current fire-alarm internal structure, it is relatively costly to be unfavorable for promoting the use of, and once there is fire, cut-out is existing After field ionization source, fire-alarm is to be stopped, and loses corresponding warning function, seriously threatens the life peace of the people Entirely.
Utility model content
The purpose of this utility model there is provided that a kind of safe and reliable, practicality is high, can power off the fire-alarm for using.
To reach above-mentioned purpose, the technical solution adopted in the utility model is as follows:A kind of fire-alarm, including fire inspection Device, warning device, battery pack, housing and base are surveyed, the fire detection device and the warning device are arranged at described On base;The fire detection device includes temperature sensing device and smoke sensing device;The warning device includes buzzer And luminous tube, the buzzer, the luminous tube, the battery pack be sequentially connected with the temperature sensing device by wire, The smoke sensing device is individually connected with the battery pack, forms two shunt circuits;The temperature sensing device includes gold Category piece a and sheet metal b, the sheet metal a and the sheet metal b are respectively fixedly disposed at the two of the lower recess of the housing Side, sheet metal a and sheet metal b distinguish the two ends of connecting wire, and the sheet metal a and sheet metal b are oppositely arranged, each other not Contact;The smoke sensing device is integration module, is provided with sound-light reminding device, is individually connected with the battery pack;The honeybee The wire that ring device, the luminous tube, the battery pack, the smoke sensing device and connection are used is arranged at the housing Interior, the housing is connected with the base buckle-type.
The sheet metal a and sheet metal b has the effect and electric conductivity expanded with heat and contract with cold.
A small fan is additionally provided with the housing, is connected with the temperature sensing device.
An aperture is provided with the housing, described luminous tube is set in the aperture.
Compared with prior art, the utility model has the characteristics that and advantage:
1. the principle that the utility model is expanded with heat and contract with cold using sheet metal, when there is fire, two sheet metal expanded by heating, that This contact, makes circuit communication, and buzzer and luminous tube work, and this mode is simple and convenient, it is easy to accomplish, and be conducive to the popularization to make With.
2. using battery pack as electric supply installation, prevented to be cut off the electricity supply because of generation fire makes fire alarm to the utility model The thing that device is stopped occurs.
3. the duplicate protection of the utility model temperature in use induction installation and smoke sensing device, more increases the fire report The security of alert device.
Brief description of the drawings
Accompanying drawing 1 is internal circuit diagram of the present utility model.
Accompanying drawing 2 is the utility model structure chart.
Wherein:1 base, 2 housings, 3 warning devices, 31 buzzers, 32 luminous tubes, 4 battery packs, 5 fire detection devices, 51 Temperature sensing device, 511 sheet metal a, 512 sheet metal b, 52 smoke sensing devices, 6 apertures, 7 small fans.
Specific embodiment
Brief description is made to specific embodiment of the present utility model below in conjunction with the accompanying drawings.
The device of a kind of fire-alarm, including fire detection as shown in Figure 1 and Figure 25, warning device 3, battery pack 4, housing 2 With base 1, it is characterised in that:The fire detection device 5 and the warning device 3 are arranged on the base 1;The fire Calamity detection means 5 includes temperature sensing device 51 and smoke sensing device 52;The warning device 3 includes buzzer 31 and lights Pipe 32, the buzzer 31, the luminous tube 32, the battery pack 4 are connected successively with the temperature sensing device 51 by wire Connect, the smoke sensing device 52 is individually connected with the battery pack 4, form two shunt circuits;The temperature sensing device 51 to include that sheet metal a511 and sheet metal b512, the sheet metal a511 and the sheet metal b512 are respectively fixedly disposed at described The both sides of the lower recess of housing 2, sheet metal a511 and sheet metal b512 distinguish the two ends of connecting wire, the sheet metal a511 It is oppositely arranged with sheet metal b512, is not contacted each other;The smoke sensing device 52 is integration module, if acousto-optic prompting Device, is individually connected with the battery pack 4;The buzzer 31, the luminous tube 32, the battery pack 4, the smoke sensing Device 52 and the used wire of connection are arranged in the housing 2, and the housing 2 is connected with the buckle-type of the base 1;Institute Stating the sheet metal a511 and sheet metal b512 has the effect and electric conductivity expanded with heat and contract with cold;One is additionally provided with the housing 2 Individual small fan 7, is connected with the temperature sensing device 51;An aperture 6,32 sets of described luminous tube are provided with the housing It is located in the aperture 6.
Under normal circumstances, infrared receiving tube can only receive faint infrared transmitting tube and be sent out in smoke sensing device 52 The infrared light for going out, sheet metal a511 and sheet metal b512 is separated from each other in temperature sensing device 51, and circuit is in situation about disconnecting; When fire occurs, produce smog first, the smoke sensing device 52 that smog enters in fire-alarm, smog by refraction, Reflection, makes the infrared receiving tube in smoke sensing device 52 receive the infrared light that infrared transmitting tube is sent, red when what is received When outer light sentences value more than setting, alert drives the sound-light reminding device on its integration module to send prompting.
Fire occurrence temperature is raised, and sheet metal a511 and sheet metal b512 on temperature sensing device 51 is with expanding with heat and contract with cold And the characteristics of conduction, therefore sheet metal a511 expands laterally with sheet metal b512 temperature influences, contacts with each other, and joins circuit Logical, the power supply of battery pack 4 makes buzzer 31 be worked with luminous tube 32, and buzzer 31, luminous tube 32 can pipe and flicker, play prompting Effect, gives people to strive for more evacuation times;To avoid because fire causes the too high defective component of temperature inside housing 2, in shell Body 2 is internally provided with a small fan 7, and circuit communication, small fan 7 is started working, the function with radiating;Housing 2 and base 1 Using the material of high temperature insulation, the service life of fire-alarm is improved;An aperture 6, luminous tube 32 are additionally provided with housing 2 It is socketed in aperture 6, is easy to be clearly visible that the reminding effect of luminous tube 32.
The utility model is powered using battery pack 4, and having prevented to be cut off the electricity supply because of generation fire makes fire-alarm stop work The thing of work occurs;Duplicate protection, the dual-alarm of smoke sensing device 52 and temperature sensing device 51 are employed again, are improve The security of fire-alarm, reliability, dual-alarm can more be attracted much attention, and people is withdrawn as early as possible.
