Since the utility model is provided with the gas misfiring escaping sensor, the amplifying circuit and the gas source control device, signals given by the sensor turns off the power supply in the gas source control device through the amplifying circuit when the gas-cooker automatically extinguishes, thus avoiding danger.
Description
Technical field
The utility model relates to a kind of gas-cooker safety guard, particularly a kind of safety guard that prevents that combustion gas continues to escape behind the gas kitchen ranges auto extinguishing.
Background technology
Gas kitchen ranges has become the essential product of people's life, and existing gas-cooker generally can use multiple fuel gas such as coke-stove gas, liquefied petroleum gas, natural gas.But because the characteristic of these fuel gas, it reaches in air and runs into naked light after certain concentration and will burn even blast, and some gas also can make the people that intoxicating phenomenon takes place simultaneously.Therefore combustion gas continues to escape after must taking measures to prevent to use the gas-cooker auto extinguishing of these fuel gas, existing gas kitchen ranges does not also all have practical anti-flame-out combustion gas to escape device, when extinguishing owing to a variety of causes, gas-cooker can't close source of the gas automatically, once carelessness fuel gas is escaped in a large number slightly, thereby produce dangerous.
The utility model content
The purpose of this utility model is to provide a kind of gas kitchen ranges safety guard that stops working, and it can produce behind the gas-cooker auto extinguishing and close source of the gas when combustion gas escapes automatically.Avoid causing danger.
The flame-out safety guard of gas kitchen ranges of the present utility model comprises flame-out sensor, amplifying circuit and the control air source equipment of escaping of combustion gas; Described combustion gas is flame-out to escape sensor and is arranged on the gas kitchen ranges, this combustion gas is flame-out to escape sensor and is electrically connected with amplifying circuit, input as amplifying circuit, the output of amplifying circuit connects control air source equipment, control air source equipment is arranged on the gas source pipeline of gas kitchen ranges, and amplifying circuit is provided with power supply.
Above-mentioned device can also comprise warning device, and this warning device can be buzzer or indicator lamp, is arranged on the output of amplifying circuit.
This above-mentioned combustion gas is flame-out, and to escape sensor can be corresponding gas sensor, is arranged on the top of gas kitchen ranges; Can be temperature-sensitive element or light-sensitive element also, be arranged on the gas stove fire head.
Above-mentioned this amplifying circuit and power supply are arranged in the housing.
This above-mentioned control air source equipment is an electromagnetic valve, is arranged on the source of the gas pipeline of gas kitchen ranges.
This above-mentioned amplifying circuit can be provided with power switch; This power switch can be provided with on the housing, also can be arranged on the gas-cooker ignitor switch, links with ignitor switch.
The gas kitchen ranges of the present utility model safety guard that stops working; because be provided with flame-out sensor, amplifying circuit and the source of the gas control magnetic valve of escaping, when the gas-cooker auto extinguishing occurring, the signal that its sensor produces removes to control magnetic valve by amplifying circuit; close source of the gas, avoid causing danger.
Description of drawings
Fig. 1 is the user mode schematic diagram of a kind of embodiment of device of the present utility model;
Fig. 2 is the circuit diagram of control circuit of the present utility model;
Fig. 3 is the user mode schematic diagram of another kind of embodiment of the present utility model.
The specific embodiment
Embodiment 1:
As shown in Figure 1; the main body 6 of safety guard of the present utility model is a housing, is provided with amplifying circuit and battery pack (all not drawing among the figure) in this housing, and amplifying circuit is connected with magnetic valve 7 by lead; magnetic valve 7 is arranged on the fuel gas pipeline 8, as the valve of control source of the gas.And on the rotary switch 4 of gas-cooker 3, being provided with power switch (not drawing), this power switch can be used press button, rotary switch 4 interlocks of itself and gas-cooker 3.On the panel of lighting kitchen range 3 as the side that this press button can be arranged on rotary switch 4, when opening, inwardly presses rotary switch 4, just can actuation button switch connection power supply.Flame-out the escaping when sensor 2 uses gas sensor of combustion gas can be arranged on the top of the kitchen range 1 on the gas-cooker 3, and can have certain distance.This gas sensor is can exchange according to different sources of the gas, during as use natural gas or liquefied petroleum gas, uses the gas sensor of alkanes gas; When using the pipeline coke-stove gas, then use gas sensor to the carbon monoxide sensitivity.
Above-mentioned combustion gas is stopped working and is escaped sensor 2 is connected to amplifying circuit by lead 5 input.
As shown in Figure 2, the output of amplifying circuit of the present utility model not only connects magnetic valve 7, and the buzzer 9 that also is connected in parallel is reported to the police when magnetic valve moves simultaneously.
Above-mentioned device of the present utility model is installed in magnetic valve 7 on the fuel gas pipeline in use, and combustion gas is flame-out to escape the appropriate location that sensor 2 is arranged on gas-cooker 3, turns on the power switch.If gas-cooker burning at this moment, just not having combustion gas escapes, produce the light and heat of burning simultaneously, combustion gas this moment is flame-out to escape sensor 2 and can not produce and flame-outly escape signal, and magnetic valve 7 just keeps original open mode, makes the gas-cooker normal combustion, behind the gas-cooker auto extinguishing, because the combustion gas meeting continues to escape, gas sensor just can induce signal, and this signal amplifies rear drive magnetic valve 7 through amplifying circuit and closes fuel gas pipeline 8 and drive buzzer 9 warnings.This utility model that is provided with gas sensor not only can be used as the protective device that gas combustion range flameout escapes, and also can be used as the protective device use that other gas leaks.
Embodiment 2:
As shown in Figure 3, the structure of present embodiment is basic identical with embodiment 1, institute's difference is, the flame-out sensor 2 that escapes of this combustion gas uses light-sensitive element, as photo resistance, simultaneously this photo resistance is arranged on the kitchen range 1 of kitchen range, according to whether having the light of burning to judge that whether gas-cooker 3 is in burning.Simultaneously magnetic valve 7 and power switch all are arranged in the main body 6, these main body 6 integral body are arranged on the source of the gas pipeline 8 of combustion gas.After the gas-cooker of lighting extinguished naturally, this photo resistance just can produce induced signal because light disappears, and this induced signal is closed by amplifying circuit amplification back control source of the gas and reported to the police.
Substantially the same manner as Example 2, the flame-out sensor 2 that escapes of this combustion gas uses temperature-sensitive element, and as thermocouple, this thermocouple also is arranged on the Burning stove hole 1, judges that according to the temperature of kitchen range 1 whether gas-cooker 3 is in burning.
