Technical field

It the utility model is related to a kind of kitchen gas stove, and in particular to a kind of safety fuel gas equipment.

Background technology

Now for the gas-cooker all used in most of families, substantial amounts of safety problem, main safety problem be present It is gas leakage, so as to cause fire and combustion gas to be poisoned, the serious security of the lives and property for jeopardizing people, in present family There is an urgent need to a kind of combustion gas auxiliary equipment, to prevent the leakage of coal gas.

The content of the invention

For above-mentioned the shortcomings of the prior art, the purpose of this utility model is to provide a kind of safety fuel gas equipment, comes Ensure the safety of gas-cooker.

To achieve the above object, the technical solution adopted in the utility model：Safety fuel gas equipment, including gas-cooker, combustion gas Pipeline, pressure-reducing valve, single-chip microcomputer, described gas-cooker are used with gas pipeline junction and are threadedly coupled, gas-cooker and gas pipeline Junction is fixed with seal box（The top of seal box is welded with gas-cooker, and the bottom of seal box and Gas Pipe are close by sealing ring Envelope, wherein following seal box uses transparent plastic box）, liquid is put into seal box（The immiscible liquid with combustion gas, such as Water）, liquid floods gas-cooker and gas pipeline threaded connection place, the gas of liquid upper in seal box drained and sealed, Seal box upper strata forms vacuum layer；Use and be threadedly coupled and in pressure-reducing valve between the pressure-reducing valve upper/lower terminal and gas pipeline The junction of upper/lower terminal and gas pipeline is respectively and fixedly provided with seal box, and liquid has equally been put into seal box, and liquid floods decompression The junction of valve and gas pipeline, vacuumize to form vacuum layer in seal box, the interface of fuel gas bottle and gas pipeline is fixed with Magnetic valve（Screw thread is provided with the import and outlet of magnetic valve, import, the outlet of magnetic valve lead to fuel gas bottle, gas pipeline respectively Cross threaded connection）, magnetic valve is connected with single-chip microcomputer by wire；Electronic nose, electronic nose are fixed with wall above gas-cooker Apart from ground 1.5 meters (height of human nose), single-chip microcomputer is connected with electronic nose by wire, and smoke exhaust ventilator is fixed on kitchen It is interior, and be in communication with the outside, single-chip microcomputer is also connected with lampblack absorber by wire.

Compared with prior art, the utility model has the advantage of by the way of fluid-tight, can timely discover interface Go out whether gas leakage, the combustion gas that human nose can't smell can be detected using electronic nose, while the stream of combustion gas can be interrupted Go out, intelligentized control makes combustion gas safe when kitchen uses.

Embodiment

In conjunction with accompanying drawing, the utility model is further elaborated.

As Figure 1-3, safety fuel gas equipment, including gas-cooker 1, gas pipeline 2, pressure-reducing valve 5, single-chip microcomputer 6, it is described For gas-cooker 1 with gas pipeline 2 using being threadedly coupled, gas-cooker 1 is fixed with seal box 3 with the junction of gas pipeline 2（Seal box 3 Top fixed with gas-cooker 1 by screw, be lined with rubber ring, the bottom of seal box 3 between the top of seal box 3 and gas-cooker 1 Sealed between gas pipeline 2 by sealing ring）, liquid is put into seal box 3（The immiscible liquid with combustion gas, such as water）, Liquid floods gas-cooker 1 and the threaded connection place of gas pipeline 2, and the gas of liquid upper in seal box 3 is drained and sealed, close The upper strata of jacket 3 forms vacuum layer 4；Used between the upper/lower terminal of pressure-reducing valve 5 and gas pipeline 2 and be threadedly coupled and depressurizing The junction of the upper/lower terminal of valve 5 and gas pipeline 2 is respectively and fixedly provided with seal box 3（Seal box 3 is sealed by sealing ring）, seal box 3 Liquid is inside equally put into, liquid floods the junction of pressure-reducing valve 5 and gas pipeline 2, vacuumizes to form vacuum layer in seal box 3 4；Fuel gas bottle 10 and the interface of gas pipeline 2 are fixed with magnetic valve 9（Screw thread, electromagnetism are provided with the import and outlet of magnetic valve Import, the outlet of valve are connected through a screw thread with fuel gas bottle 10, gas pipeline 2 respectively）, magnetic valve 9 connected with single-chip microcomputer 6 by wire Connect；Electronic nose 7 is fixed with the wall of the top of gas-cooker 1, electronic nose 7 is apart from ground 1.5 meters (height of human nose), monolithic Machine 6 is connected with electronic nose 7 by wire, and smoke exhaust ventilator 8 is fixed in kitchen, and is in communication with the outside, and single-chip microcomputer 6 is gone back and lampblack absorber 8 are connected by wire.

The practical single-chip microcomputer 6 of the utility model is STC11F60XE, the model ZCD-2 of magnetic valve 9, the type of electronic nose 7 Number it is CPR-100.

When in use, when routine use, when people is around gas-cooker 1, when the generation coal gas of interface When leakage, due to the vacuum layer 4 in seal box 3, the air pressure in gas pipeline 2 is more than the air pressure in seal box 3, Gas Pipe Combustion gas in road 2 is slowly escaped through, and bubble is produced in the liquid of seal box 3, after people is by being visually observed bubble, and timely Interface is repaired, when being the gas leakage caused by closing the rupture of the upper tube wall of gas pipeline 2 or pressure-reducing valve 5, due to combustion The density of gas is less than air, and combustion gas can ramp, and when electronic nose 7 detects combustion gas, electronic nose 7 feeds back information to monolithic Machine 6, single-chip microcomputer 6 control magnetic valve 9 to close with starting smoke exhaust ventilator 8 simultaneously, combustion gas are discharged outdoor.
