The specific embodiment:

The self-timing shutoff device of gas kitchen ranges of the present utility model comprises mechanical timer, and the timing disc 1 of band groove 2 is housed on the timer central shaft, and the next door of groove 2 is provided with another little groove 3; Comprise the timing action disk 14 that is fixed on the kitchen range ignition switch axle, the timing reset dish 15 that has cam, clutch block 17 is arranged on the timing reset dish, it can be meshing with each other or separate with the clutch block 18 of Range switch axle, and being equipped with on the timing reset dish can be with the return spring 16 of timing reset dish pop into position.Also comprise the U-shaped connecting rod 4 that connects timing reset dish 15 and timing disc 1, above-mentioned U-shaped connecting rod 4 has a moving fulcrum 12, an end of connecting rod have with timing reset dish 15 on resetting of acting on mutually of cam argue for the sake of arguing 22 and play the regularly impact block 23 of closing function; The other end of U-shaped connecting rod has with timing disc 1 act on the swing arm 5 that can swing mutually between two link stopper 6, on the top of this swing arm 5 roller 11 is installed, and the swing arm side of U-shaped connecting rod is provided with stage clip 7.On the U-shaped connecting rod, be fixed with spring 13, be used for keeping connecting rod elastic impact power.Reset 22 sides of arguing for the sake of arguing of U-shaped connecting rod are equipped with tooth bar 19, and the closing motion piece 20 that acts on mutually with foregoing impact block 23 is housed on the tooth bar.Tooth bar 19 slides up and down in the chute 21 of support 24.Regularly action disk 14 is provided with gear, and itself and above-mentioned tooth bar interact.When pushing downwards when opening ignition switch, ignition switch is opened, and drives regularly action disk 14 and rotates, and timing reset dish 15 is rotated because of the clutch block 17 on the 18 engagement timing reset dishes of the clutch block on the ignition switch axle; Regularly move on gear driven tooth bar 19 on the action disk 14 and the closing motion piece 20, cam jack-up on the reseting disk resets and argues for the sake of arguing 22 simultaneously, at this moment connecting rod interlock, the roller 11 of the groove 2 that is arranged in timing disc 1 is broken away from groove 2, and under the effect of the stage clip 7 of connecting rod, enter in the little groove 3, because roller enters in the little groove, even kitchen range are subjected to necessarily shaking also can not producing misoperation like this.At this moment kitchen range igniting finishes, and when unclamping ignition switch, the clutch block 17 on the timing reset dish separates with clutch block 18 on the Range switch axle, the timing reset dish original position of rebounding under the effect of return spring 16.Rotate timer as required, the effect that roller in little groove is rotated by timing disc, swing to the other end from an end of stage clip elastic force effect, make the grab 9 on the U-shaped connecting rod block the fixture block 8 of swing arm 5 ends, this fixture block 8 preferably is formed on the oblique angle structure of swing arm 5 ends.When timer regularly finished, the roller of swing rod end resetted in groove 2, and grab 9 separates with fixture block 8 under the effect of a fixing grab declutcher control lever 10 simultaneously.At this moment, under the interlock effect of connecting rod, the resetting of connecting rod argued for the sake of arguing and 22 moved down, and makes that closing impact block 23 presses down closing motion piece 20 on the tooth bar, and tooth bar acts on gear, and then rotates ignition switch is closed.

In sum, compared with prior art, the utility model provides an automatic timer, timer itself and kitchen range point Fire can link each other by a connecting rod between the switch, therefore, uses again igniting behind the timer needn't carry out timer Switch resets, but directly enables the kitchen range ignition switch, can normally use, and is safe and simple and made things convenient for user, maximum Limit guarantees that the user is by original custom operation.
