Description
Technical field
The utility model relates to a kind of signal that is produced when survey leaking combustion gas or flame temperature and the device of control burnt gas valve and foamite container valve, especially a kind of household kitchen extinguishing device.
Background technology
At present, household kitchen fire-fighting equipment product on the market has Fuel Gas Leak Alarm, and when combustible gas leakage took place, it can be sounded, the caution people, but can not prevent fuel gas to continue to leak, the palpus people more can not put out a fire for closing gas valve.Second kind is the gas leakage controller, and it can not only leak combustion and report to the police, and closes gas valve simultaneously, and blast tube is cut off, and prevents to continue to leak.But when gas furnace catches fire when causing fire, more than two kinds of products all have and can not put out a fire.
In addition, China utility model CN233740Y discloses a kind of kitchen automatic fire extinguisher, it records the flame that is burnt and produce accidentally by oil in the cooker automatically by the fire detector that is installed in the gas-cooker top, and to the signal of driver output breaking out of fire, driver is opened the extinguishing chemical cylinder valve immediately, extinguishing chemical passes through plumbing nozzle, and by the direction of setting, extinguishes the blaze.Simultaneously, close the supply valve of the gas-cooker of breaking out of fire automatically, prevent the secondary resume combustion.
Yet, this extinguishing device can not be surveyed gas leakage, and, (for example fire temperature is not set at 180 degree when temperature reaches fire temperature as yet, this moment, local temperature was 60 degree), not necessarily will start extinguishing device this moment puts out a fire, but has certain danger, only needs gas valve is cut off and can remove the dangerous condition.At this moment, this kind extinguishing device just is unable to cope with.
Summary of the invention
The utility model overcomes the deficiencies in the prior art, and a kind of kitchen automatic fire extinguisher is provided, and this device can not only detect the leakage of combustion gas, automatically shut down blast tube when finding gas leakage, and can carry out temperature detection, when breaking out of fire, spraying fire-extinguishing agent is put out a fire automatically.Specifically, the utility model is achieved by following technical proposals: a kind of household kitchen extinguishing device, has hygrosensor, the extinguishing chemical storage container, pipeline, nozzle, the motor-driven container value, controller, the source of the gas stop valve, especially, described controller comprises testing circuit, charging circuit, relay, warning circuit, photoelectric switching circuit, the fuel gas shutoff circuit, motor-drive circuit, wherein, its input of described testing circuit respectively with charging circuit, the signal input part of relay circuit is connected, the output of described testing circuit respectively with described warning circuit, photoelectric switching circuit, the signal input part of motor-drive circuit is connected; Described photoelectric switching circuit output is connected with the signal input part of described fuel gas shutoff circuit, and described its output of fuel gas shutoff circuit is connected with the output of described charging circuit, relay, warning circuit, motor-drive circuit respectively.
Compare with existing kitchen extinguishing device, substantive distinguishing features that the utlity model has and technological progress are conspicuous: described device can be closed gas valve at once and be sent alarm sound immediately when gas leakage takes place, and prevents that combustion gas from continuing to leak; When gas-cooker causes the condition of a fire because of some reason, especially when temperature reached first threshold value, this device can be closed the combustion valve at once and be sent alarm sound; When the intensity of a fire continued to increase the temperature rising above second threshold value, this device can discharge extinguishing chemical immediately and extinguish the blaze.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail; The utility model relates to a kind of household kitchen extinguishing device, has hygrosensor 5, combustible gas probe 6, extinguishing chemical storage container 2, pipeline 3, nozzle 4, motor-driven container value 1, controller 7, source of the gas stop valve 10, wherein, described controller 7 comprises testing circuit 73, charging circuit 71, relay circuit 72, warning circuit 76, photoelectric switching circuit 77, fuel gas shutoff circuit 79, motor-drive circuit 78, and, described testing circuit 73 its inputs respectively with charging circuit 71, the signal input part of relay circuit 72 is connected, the output of described testing circuit 73 respectively with described warning circuit 76, photoelectric switching circuit 77, the signal input part of motor-drive circuit 78 is connected; Described photoelectric switching circuit 77 outputs are connected with the signal input part of described fuel gas shutoff circuit 79, and described fuel gas shutoff circuit 79 its outputs are connected with the output of described charging circuit 71, relay circuit 72, warning circuit 76, motor-drive circuit 78 respectively.The hygrosensor 5 and the combustible gas probe 6 that in described testing circuit 73, also comprise at least more than one, and an end of described hygrosensor 5 is connected with described motor-drive circuit 78.On the body of described extinguishing chemical storage container 2, also be provided with the Interface Terminal 21 that is connected with described motor-driven container value 1.In addition, between described charging circuit 71 and relay 72, be provided with one group have two above contact A, B's and have the conversion switch of rechargeable battery 7A.In the practice,, just do not need pressure-reducing valve 9 if adopt pipeline liquefied gas or natural gas system.Controller 7 links to each other with combustible gas probe 6, hygrosensor 5 respectively by line; Combustible gas probe 6 and hygrosensor 5 carry out double check, and pass through the setting of controller 7, control source of the gas stop valve 10 and motor-driven container value 1.Rise to first threshold value and control source of the gas stop valve 10 and close source of the gas when detecting combustible gas leakage or temperature, after temperature rose to second threshold value, drive motors drove the fire extinguishing of container value 1 spraying fire-extinguishing agent.When combustible gas probe 6 detects gas leakage, gas sensing resistance resistance in the combustible gas probe 6 descends, high by testing circuit 73 outputs, trigger fuel gas shutoff circuit 79 by photoelectric switching circuit 77, close origin stop valve 10, cut off blast tube, avoid combustion gas to continue to leak, and give the alarm.On the other hand, when room temperature rises above first threshold value, hygrosensor 5 (generally adopting thermistor) heated resistance diminishes, by testing circuit 73 output high level, trigger fuel gas shutoff circuit 79 by photoelectric switching circuit 77, close source of the gas stop valve 10, cut off blast tube, avoid gas to continue to leak, and give the alarm.Rise when the room temperature continuation, when surpassing second threshold value, hygrosensor 5 (generally adopting thermistor) resistance further diminishes, testing circuit output high level, and conducting motor-drive circuit 78 is opened dispenser valve, discharges extinguishing chemical and extinguishes the blaze.Wherein first threshold value is set up defences and is decided to be 50 degree, and second threshold settings is 80 degree.
In Fig. 2, provide power supply for entire circuit by transformer.When civil power just often, switch connects the A point, rechargeable battery 7A carries out intermittent charge, the lamp of indication power supply is bright.When civil power hinders and can not normal power supply the time, relay loses power supply for some reason, its normally-closed contact connects, and switch connects the B point, and rechargeable battery 7A provides stand-by power supply for entire circuit.
Although the utility model has been done detailed explanation and quoted concrete example as proof,, obviously can make all replacement schemes, modification and change according to above-mentioned explanation for those of ordinary skill in the art.Therefore, all these replacement schemes, correction and change all should be included within the spirit and scope of claim.
