Description
Technical field
The utility model relates to a kind of checkout gear, specifically is a kind of gas safe electronic detecting device that is used for gas-cooker.
Background technology
In recent years, along with the develop rapidly of China's urban and rural economies, combustion gas is applied in national economy every field and the urban and rural households life more and more widely.Be accompanied by the large-scale application of combustion gas, how not only safe but also use combustion gas economically, become the problem of people's extensive concern.Especially in family used, not only may there be leakage in fuel gas pipeline, when also having infusion gruel, gruel overflows gas-cooker is extinguished, and can cause gas leakage equally, can not in time find as the user, not only cause combustion gas waste, when serious even the personal safety that jeopardizes the user of resident family.
Summary of the invention
The utility model for can safety, use combustion gas economically, a kind of gas safe electronic detecting device is provided.
The utility model is to adopt following technical scheme to realize: the gas safe electronic detecting device, comprise operating mechanism and control circuit, described operating mechanism comprises tubular valve rod, and it axially has two adjacent passages the tubular valve rod upper edge, is provided with partition between two passages in the tubular valve rod; In being with, establishes tubular valve rod the tubular valve body of boss outward, between tubular valve rod and the tubular valve body, the boss both sides of the tubular valve body retainer ring that is used to fix rubber seal that is respectively equipped with rubber seal and cooperates with the tubular valve body inner thread, the side of giving vent to anger of tubular valve rod is fixed with solenoid, be provided with back-moving spring between tubular valve body and the solenoid, the air inlet side of tubular valve rod is provided with the limited block that is used to limit the tubular valve body moving range, is between two passages in the give vent to anger rubber seal of side of tubular valve rod; Described control circuit comprises and is parallel to being surveyed the sound and light alarm switch module and be fixed in the tubular valve rod current supply circuit that solenoid series connection on the side constitutes of giving vent to anger by gas combustion range ignition switch, combustion gas of power supply E two ends, the solenoid two ends are parallel with existing igniting contact, and the gas combustion range ignition switch ends is parallel with the temperature detect switch (TDS) that is arranged at gas-cooker port place.
During use, the utility model is installed on the air inlet pipe place at the gas-cooker back side, be communicated with fuel gas pipeline and gas-cooker, rotate the gas combustion range ignition switch, make the current supply circuit conducting of control circuit, solenoid gets, tubular valve body is produced suction, the tubular valve body band rubber seal and is moved along the direction of tubular valve rod to solenoid, two passages on the tubular valve body are between two rubber seal, make the air inlet side of tubular valve rod and the side of giving vent to anger be in conducting state, gas-cooker is in normal state of ventilation, and igniting contact is lighted the gas-cooker port; As because during infusion gruel, gruel overflows gas-cooker is extinguished, temperature descends, the temperature detect switch (TDS) that is in normally off that is arranged at gas-cooker port place disconnects, the current supply circuit of control circuit is disconnected, the solenoid dead electricity, suction to tubular valve body disappears, under the effect of back-moving spring, the tubular valve body band rubber seal and is moved along the direction of tubular valve rod to limited block, stops until propping up limited block, is in again between two passages in the give vent to anger rubber seal of side of tubular valve rod, the air inlet side of tubular valve rod and the side of giving vent to anger are in by state, reach the purpose of turn-offing fuel gas pipeline; Work as gas pipeline leakage, and when concentration acquires a certain degree, the disconnection of sound and light alarm switch module is surveyed in the combustion gas that is in normally off, the current supply circuit of control circuit is disconnected, and as above-mentioned process, fuel gas pipeline is turn-offed, send sound and light alarm information simultaneously, remind the user to note, to reach the purpose of safe handling.Described temperature detect switch (TDS) is existing known products, and original state is an off-state, is in closure state when temperature reach a certain height, disconnect when temperature is low, and can be by buying on the market; It is existing known products that the sound and light alarm switch module is surveyed in described combustion gas, original state is a closure state, has the function of gas monitoring, can carry out sound and light alarm when gas concentration transfinites, and finish corresponding disconnection, closed switching manipulation, can be by buying on the market.
The utility model is simple and reasonable for structure, and result of use is good, has market popularization value well.
