The protective circuit for the disabled ignition of the gas stove can not only resolve the problem of difficult ignition of the gas stove with a thermocouple extinguishment protective function, but also resolve the potential safety hazard caused by gas leakage due to effectiveness losing of components.
Description
Technical field
The utility model relates to the gas-cooker field, particularly a kind of gas combustion range ignition circuit with blowout protection.
Background technology
Fig. 1 is the fast ignitor of gas-cooker on the existing market, comprises igniter, thermocouple, button ignition switch, delay circuit, magnetic valve, driving circuit for electromagnetic valve.When user's button ignition switch of pressing and outward winding, by the igniter igniting, delay circuit can keep magnetic valve to open about 10 seconds, guarantee that thermocouple obtains good flame induction, subsequently, driving circuit for electromagnetic valve is stopped power supply, thermocouple produces the unlatching that electric current is kept magnetic valve, and burning is continued.This design makes and need not to pin for a long time button ignition switch when the user lights a fire.
Capacitor discharge finishes in delay circuit, and driving circuit for electromagnetic valve will quit work, and this moment, gas-cooker was kept the unlatching of magnetic valve by the flame heat thermocouple, had still satisfied the requirement of blowout protection in theory.But; because any components and parts all have the possibility of inefficacy; electronic switch in above-mentioned driving circuit for electromagnetic valve is short-circuited; (battery electric quantity exhaust before) then within a certain period of time; the coil of blowout protection valve can be in "on" position all the time; the extinguish protection function of gas-cooker will lose efficacy, and the major safety risks of gas leakage and blast are arranged.
Therefore, how when realizing quick ignition function, to guarantee that unaffected those skilled in the art of being of extinguish protection function of magnetic valve need the technical problem of solution badly.
The utility model content
The technical problems to be solved in the utility model provides a kind of gas combustion range ignition fail-safe circuit, not only can realize quick igniting, and can solve above-mentioned safety problem.
The utility model proposes a kind of gas combustion range ignition fail-safe circuit; comprise power supply, the igniter that links to each other with power supply and magnetic valve, the button ignition switch of between power supply and magnetic valve, connecting, delay circuit, driving circuit for electromagnetic valve; it is characterized in that, also comprise the holding circuit in parallel with driving circuit for electromagnetic valve.
Further, holding circuit comprises resistance R 5 and the metal-oxide-semiconductor TS3 that is connected in series, and wherein, resistance R 5 links to each other with delay circuit, and metal-oxide-semiconductor TS3 links to each other with magnetic valve.
Further, metal-oxide-semiconductor can be replaced with electronic switches such as relay or triodes.
Further, the electromagnetic valve coil two ends are in parallel with above-mentioned electronic switch.
Further, also comprise being connected in parallel of a plurality of driving circuit for electromagnetic valve and holding circuit.
The utility model not only can solve the problem of band thermocouple extinguish protection function gas combustion range ignition difficulty, has also solved the potential safety hazard of the gas leakage that produces owing to the components and parts inefficacy.Entire circuit is simple in structure, and is with low cost, applicable to any electric power system more than the 1.2V.
Description of drawings
Below be that the utility model is described in further detail in conjunction with the accompanying drawings:
Fig. 1 is the fast ignitor of gas-cooker on the existing market.
Fig. 2 is a kind of cold run holding circuit schematic diagram that the utility model provides.
Fig. 3 is the utility model cold run holding circuit physical circuit figure.
The specific embodiment
Specifically; Fig. 2 is the schematic diagram of a kind of cold run holding circuit of providing of the utility model; igniter (3) that comprise power supply (1), links to each other and magnetic valve (8), the button ignition switch (2) of between described power supply and described magnetic valve, connecting, delay circuit (4), driving circuit for electromagnetic valve (7) with described power supply; it is characterized in that, also comprise the holding circuit in parallel (6) with driving circuit for electromagnetic valve.
Holding circuit comprises resistance R 5 and the metal-oxide-semiconductor TS3 (referring to Fig. 3) that is connected in series, and wherein, metal-oxide-semiconductor TS3 can also replace with electronic components such as relay or triodes.Holding circuit can only be controlled closed electromagnetic valve, and can not control its unlatching.When driving circuit for electromagnetic valve work and holding circuit disconnection, electromagnetic valve coil can be worked.
The protection philosophy that the utility model provides is, electromagnetic valve coil two ends electronic switch in parallel.When button ignition switch is not pressed, when delay circuit was not worked, electronic switch was in closure state, and electromagnetic valve coil is by short circuit, and this moment, no matter whether drive circuit moved, and magnetic valve all can not worked.
Below in conjunction with Fig. 3 the concrete annexation of the utility model cold run holding circuit is described.
When button ignition switch (2) is pressed, igniter (3) work produces high-voltage pulse, capacitor C in the delay circuit (4) 1 charging simultaneously also is full of rapidly, the C1 positive pole presents high level makes metal-oxide-semiconductor TS3 source electrode and drain electrode produce high impedance and while turn-on transistor TS1, triode TS2 conducting in the TS1 conducting output low level control driving circuit for electromagnetic valve (7), magnetic valve (8) coil electricity makes that magnetic valve is held.
After unclamping button ignition switch, capacitor C 1 is slowly discharged by resistance R 1, R4, magnetic valve (8) coil continues energising and keeps holding of magnetic valve, after thermocouple (5) has obtained enough flame inductions, the adhesive that thermocouple (5) keeps magnetic valve for magnetic valve (8) coil power supply, that guarantees to burn continues.
When capacitor C 1 was discharged to voltage and is lower than the triode threshold voltage, TS1 closed, and TS2 also closes thereupon, and TS3 source electrode and drain electrode simultaneously produces Low ESR makes the coil of magnetic valve (8) by short circuit, guarantees that magnetic valve (8) is controlled by thermocouple only.
When component failure causes TS1 or the unexpected unlatching of TS2, because capacitor C 1 positive pole is in low level, present Low ESR between TS3 source electrode and drain electrode, magnetic valve (8) coil has been guaranteed the normal of gas combustion range flameout defencive function by short circuit.And because the short circuit of TS3, battery electric quantity can exhaust rapidly, and the user can find in time that this is unusual.
The utility model when being applied to multiple head, only needs many these holding circuits of cover to realize applicable to single burner or multiple head, promptly also comprises being connected in parallel of a plurality of driving circuit for electromagnetic valve and holding circuit.Such as, when being applied to two burners, only needing two these drive circuits of cover, three burners are exactly three covers, and the rest may be inferred, has extremely strong extensibility.
The above only is a preferred implementation of the present utility model; should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model principle; described holding circuit is made some improvements and modifications; such as replacing metal-oxide-semiconductor TS3 etc. with electronic components such as relay or triodes, these improvements and modifications also should be considered as protection domain of the present utility model.
