Abstract
The utility model discloses a safety timing switch for a domestic gas stove, which can be used by matching with an existing domestic gas stove and can be matched with a new productive gas stove. The switch is provided with an electric pulse igniter, and the switch can automatically close a gas valve to extinguish the fire of a stove after pressing the time required to select. When the stove suddenly extinguish the fire caused by blowing the wind or the spillover of the boiling water and vegetable soup in the course of the operation, the switch can automatically and rapidly closed the gas valve, and gas poisoning and a fire hazard are prevented. The utility model has the advantages of high safety, and low cost. The safety timing switch for the domestic gas stove is convenient, and can be matched with an alarm buzzer.
Description
The utility model relates to a kind of burner gauge tap, especially house coal steam stove gauge tap.
Be not equipped with regularly and the switch of safety during house coal steam stove product export at present, if when gas burner is stopped working, need the people and wait the switch of closing the stove burner, as away from stove, not only often look after the stove switch back and forth, sometimes it is out-of-date also can to burn, and burns out food and cooker, wastes coal gas again, if institute's boil water or vegetable soup overflow fray-out of flame in the combustion process, perhaps run into a burst of wind suddenly with fray-out of flame,, cause gas poisoning easily or lead to fire if the sole is unattended.The utility model develops on CN87214294U " house coal steam stove timing control switch " basis.
The purpose of this utility model provide a kind of economy, can be with existing house coal steam stove supporting and for the supporting electromechanical type of new production gas burner regularly, safety switch.The utility model can not only be in the selected on demand time, automatically close gas valve, make stove flame-out, and in seclected time, running into stops working suddenly overflows as institute's boil water or vegetable soup, when perhaps running into a gust of wind stove fire being extinguished, can close gas valve by automatic emergency, guard against gas poisoning and prevent that fire from taking place.The utility model is safe in utilization, convenient, is convenient to general family and uses, and also can be generalized on the similar devices and use.
The utility model is by timer (8), micromotor (7), and driving gear set (19,20,21,22,23,24,25), wiring board (12), battery (16), the power switch detent mechanism, ignition mechanism, safety device is formed.The power switch detent mechanism is by gear bush (14), sliding sleeve (15), and spacing ring (2), location fork (5), damping spring (6), cam (10), power switch (3) is formed.Ignition mechanism is by ignition switch (27), electronic impulse ignition apparatus (13), and the second button ignition switch switch (17) is formed.Safety device is by sensor (30), sensor shell frame (38), and support (32), noseplate (35), cam (28), spring (37), power switch (29) is formed.
Concrete structure and function are as follows:
Gas burner gas valve control lever (1), be inserted in gear bush (14) and the sliding sleeve (15), control lever (1) is fixing with screw (26) with sliding sleeve (15), sliding sleeve (15) can slide in gear bush (14) keyway, the position of Fig. 1 middle gear axle sleeve (14) is that gas valve is in the closed position, when valve controling rod driven gear axle sleeve (14) when clockwise rotating, and the contact of the ignition switch on the sliding sleeve (27) contact, produce the electronic impulse spark, the some coal gas.Spacing ring on the gear bush (2) is along with rotation, break away from the spring (4) on the fork of location, the location fork is outside the stressed effect swing in two ends, because the damping action of four pin damping springs (6), at any time remain static, so the location fork still is in the original position state, power switch (3) still is in open-circuit condition.Fix a cam (10) cam on timer (8) axle when 0 °-5 ° of dial (9) scales, corresponding location fork (5) is the least radius of cam with the cam contact position, during to 5 ° of scales, radius increases suddenly, and the radius of later each point is that small increase is arranged gradually.When timer knob (18) when beginning to rotate clockwise, contactor on the locator (11) begins to open, circuit breaker, when knob goes to 5 ° of scales, cam (10) promotes location fork (5) connects power switch (3), after (if can rotate during less than 5 ° seclected time surpass 5 ° then return selected scale) knob forwards required seclected time to, beginning is returned counterclockwise, cam (10) is also in company with returning, location fork (5) is still in the position that makes the power switch closure, and cam disengages with the location fork immediately.When timer knob (18) return-to-zero position, contactor (11) closure, entire circuit is connected, motor (7) starts, and driven gear group (19,20,21,22,23,24,25) makes gear bush (14) drive valve controling rod (1) and rotates counterclockwise, when gear bush turns back to original position, valve controling rod is closed gas valve, and stop collar (2) promotes location fork (5) opens circuit power switch (3), and motor stops operating.When safety device rotates at valve controling rod (1), the coal gas ignition burning, cam (28) is connected the power switch (29) of temperature sensor, when temperature sensor (30) when not using, because the axle of knob (33) is connected with sensor shell frame (38), knob (33) forwards zero on the dial (34) to, makes sensor downward, leave near the flame zone, sensor quits work.When using, knob (33) forwards 2 seconds of position preheating of dial (34) scale 1 to, the temperature control element thrermostatic bimetal-plate of sensor separates contact (31), knob forwards the position of scale 2 to then, going up wiring point by wiring point (36) on the sensor shell frame (38) and the noseplate that is fixed on support (32) (35) is connected, electric wire one end on the sensor is connected with power switch (29), the other end is connected with motor (7), if the boiling water that runs into wind or boiled, vegetable soup overflows, when making fray-out of flame, coal gas is also in outside supply, at this moment, and near the temperature decrease flame zone, bimetal leaf temperature in the sensor (30) descends, contact (31) engages, and connects circuit and makes motor start-up, passes through gear train, gear shaft drives valve controling rod (1) and rotates counterclockwise, until cam (28) is when turning back to the starting position, valve controling rod is closed gas valve, and cam (28) cuts off the power switch (29) of sensor, guards against gas poisoning and the fire generation.When regularly using simultaneously with safety device, suddenly flame-out, except that the power switch of above-mentioned cut-out sensor, simultaneously before cam (10) no show starting position, one end of location fork (5) can't enter the least radius place of cam (10), and spring (4) can promote power switch (3) and cut off the electricity supply.

Embodiment:
Embodiment 1, generally uses gas burner, and timer knob (8) does not rotate, and location fork (5) is because damping spring (6) effect is in the origin-location, and power switch (3) is in open circuit, and power supply is obstructed.Valve controling rod (1) can freely be opened on demand, lights a fire, be closed.In the time of need using peace to use device, sensor knob (33) can be forwarded to scale 1 place, be placed on 2 places then, run into when stopping working suddenly, power switch (29) connected during owing to the valve controling rod Open valve.Stove one is flame-out, and the contact of sensor (31) engage, and make motor start-up, guarantees in time to close gas valve.Simultaneously, cam (28) makes power switch (29) open circuit, motor stall.
Micromotor adopts 1.5-6 volt dc motor, and power supply can adopt dry cell, perhaps uses civil power through the transformation rectification.The second button ignition switch switch uses when being second kitchen range eyespot fire.But safe and timing switch adapted buzzer.
