The specific embodiment
Below with reference to the drawings and specific embodiments, the utility model is described in further details:
Embodiment 1:
As shown in Figure 1-2, a kind of vehicle extinguishing device, comprise control circuit and fire extinguisher; Control circuit comprises power supply circuits, branch road and temperature control branch road detonate; Power supply circuits, detonate branch road and all parallel connections of temperature control branch road;
In power supply circuits, two termination car direct current power supplies of the coil of relay J 1; The central contact of relay J 1 is as the positive output end of power supply circuits; Another output of power supply circuits is ground; The normally opened contact of relay J 1 connects the anode of car direct current power supply; The normally-closed contact of relay J 1 connects the anode of automobile standby battery; Automobile standby battery and car direct current power supply are altogether;
The route temperature sensing cable 6 that detonates is in series with igniter 4, and igniter is arranged in fire extinguisher, for triggering fire extinguisher;
The coil that route temperature detect switch (TDS) 3 and relay J 2 are propped up in temperature control is in series; The normally closed switch K2 of relay J 2 correspondences is serially connected in oil supply circuit.[when relay J 2 normally closed switch disconnect, oil supply circuit opens circuit, and fuel cut-off is removed hidden danger, the protection automotive safety]
Fire extinguisher comprises the absorbing and cooling temperature layer 5 that the extinguishing chemical 2 of filling in container 1, container and container top arrange; Igniter is arranged in extinguishing chemical; Described temperature detect switch (TDS) 3 is arranged in the sidewall of container.
The material of absorbing and cooling temperature layer is magnesium carbonate; Container adopts fire-resistant cotton material; Extinguishing chemical is S type aerosol.
The automobile fire extinguishing method that vehicle extinguishing device is corresponding: adopt aforesaid vehicle extinguishing device;
Carry out electrical source exchange by relay J 1 switching; When car direct current power supply has electricity, the normally opened contact of relay J 1 and intermediate contact conducting, be branch road and the power supply of temperature control branch road of detonating by car direct current power supply; Car direct current power supply is during without electricity, and the normally-closed contact of relay J 1 and intermediate contact conducting, be detonate branch road and the power supply of temperature control branch road by automobile standby battery;
Start fire extinguisher by the branch road that detonates with temperature sensing cable and igniter, temperature sensing cable is short circuit after being heated, and igniter detonates, the spray fire extinguishing agent fire extinguishing;

The vehicle extinguishing device control principle:
Power unit: this circuit adopts the input of two-way power supply, is respectively the input of automobile DC12V power supply and internal backup battery DC12V.The switching of two-way power supply is completed by relay J 1 and contact K1.J1 obtains after vehicle-mounted 12V power supply moving K1 under normal circumstances, the central contact of K1 and normally opened contact closure, and now by vehicle power, being given fire extinguishing and cut the fuel feeding control circuit provides power supply, and reserve battery is in Light Condition.If automobile power source can not provide power supply to extinguishing device for some reason, now the coil of J1 can not get power supply, releasing contact K1, and being given fire extinguishing and cut oil supply circuit by reserve battery provides power supply.
The fire extinguishing part: before automobile during case generation fire alarm, the rear short circuit of being heated of the temperature sensing cable on deck lid, power supply makes the igniter action by temperature sensing cable, and igniter starts to trigger the extinguishing chemical release medicine and starts fire extinguishing.
Cut the fuel feeding part: the heat-sensing device on vehicle extinguishing device is in open-circuit condition under normal circumstances, and J2 is failure to actuate, and K2 is in normally off, to guarantee the oil pump normal operation.When breaking out of fire discharges extinguishing medium, heat-sensing device is subject to the high temperature triggering to be low resistance, and now J2 will move, and make K2 in off-state, stop the power supply of oil pump, cut off fuel feeding, prevent that the intensity of a fire from continuing to spread.
The effect of electric detonator is point quick-fried (startup) extinguishing medium, makes medicament start to eject;
Temperature-sensitive feedback device (also being called temperature detect switch (TDS)) belongs to off-state at ordinary times, the resistance infinity, and when temperature is elevated to 85 while spending, thermistor is considered as short circuit, makes the coil electricity of relay J 2;
Temperature sensing cable is for temperature sensor, and when external temperature moment raises and reaches the startup value, horse back starts electric detonator and spraying medicine.
