Description of drawings
Fig. 1 is circuit theory diagrams of the present invention.
The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Referring to Fig. 1; A kind of igniting of gas kitchen ranges and brake apparatus; Comprise battery power circuit, it comprises battery B and switch S, and battery B is 1.5V in the present embodiment; Its negative pole is connected to the negative pole of electronic ignition device 2 and the negative pole of deceleration of electrons device 3; Positive pole is connected to an end of switch S, and the other end of switch S is connected to the operating voltage anodal (+1.5V end) of electronic ignition device 2, the anode of thermocouple T and the casing 1 of gas kitchen ranges, and promptly the anode of thermocouple T also is connected with the casing 1 of gas kitchen ranges.Break-make through switch S is switched between battery and the civil power realizing back and forth.
The two ends of thermocouple T are connected in parallel to magnetic valve Jm, and the anode of thermocouple T connects the positive pole of magnetic valve Jm, and the negative terminal of thermocouple T connects the negative pole of magnetic valve Jm.Because during braking; Stalling current is fixing and unique through the direction of magnetic valve Jm; Therefore the brake voltage positive pole of deceleration of electrons device 3 is connected the negative terminal of thermocouple T, i.e. the negative pole of magnetic valve Jm, the operating voltage of deceleration of electrons device 3 anodal (+1.5V end) is connected to casing 1.
Be short-circuited in order to prevent that electronic ignition device 2 and deceleration of electrons device 3 directly is connected with battery B, thereby cause and to light a fire and the fault of braking etc., between the operating voltage positive pole of the negative pole of battery B and electronic ignition device 2; Be parallel with clamped spacer assembly; Clamped spacer assembly defines the minimum output voltage of battery power circuit, is short-circuited avoiding, and clamped spacer assembly can use diode, triode etc.; In the present embodiment, clamped spacer assembly is a diode.Because battery B is 1.5V; And the forward voltage drop during diode current flow is generally 0.7V; Therefore, clamped spacer assembly comprises three diodes of D1, D2, D3 of series aiding connection, and the negative pole of diode D1 is connected to the negative pole of battery power circuit; The positive pole of diode D3 is connected to the positive pole of battery power circuit, the voltage of later pressure drop greater than battery B of connecting.Alternately, when adopting the battery B of other voltages, the quantity of diode changes thereupon, as long as guarantee to connect the voltage of later pressure drop greater than battery B.
The mains ac power supply of 220V converts the operating voltage anodal (+1.5V end) that is connected to deceleration of electrons device 3 behind the direct current of 1.5V to through transformer; Be provided with microprocessor in the deceleration of electrons device 3; When civil power just often; The microprocessor gauge tap S of deceleration of electrons device 3 opens after igniting, uses mains supply; When city's electrical anomaly, the microprocessor gauge tap S of deceleration of electrons device 3 is closed, uses battery B as power supply.
The principle of the present invention and the course of work are following:
When city's electrical anomaly used battery B as the power supply of electronic-controlled installation 3, microprocessor gauge tap S was in closure state all the time.After gas kitchen ranges is lighted a fire successfully, keep the adhesive of magnetic valve Jm through the voltage that thermocouple T produces, thereby guarantee the unobstructed of combustion gas, can heat pan etc.After the timing of gas kitchen ranges arrives; Microprocessor sends signal to deceleration of electrons device 3, the brake voltage positive pole of controlling deceleration of electrons device 3 thus to one of magnetic valve Jm output during with operate as normal through the opposite electric current of current polarity of magnetic valve Jm, promptly electric current flows to positive pole from the negative pole of magnetic valve Jm; This moment is because the clamped effect of diode; Avoid battery B short circuit, thereby realized the shared of priming supply and braking power, the simple and safe practicality of circuit structure.Magnetic valve Jm under the state of adhesive logical during opposite polarity electric current, when the magnetic force that is produced, enough offset the magnetic force of original adhesive after, magnetic valve Jm discharges and closes, and breaks off the path of combustion gas, thereby cuts off burning things which may cause a fire disaster.
The above is merely preferred implementation of the present invention, should be pointed out that for those of ordinary skill in the art, not breaking away under the principle prerequisite of the present invention, can also make various deformation and improvement, and this also should be regarded as protection scope of the present invention.
