Example 1

An automatic ignition device of a gas stove comprises a knob 1, a rotating shaft 2, a threaded shaft 3, a rectangular frame 4 and a stepping motor 5;

referring to fig. 1, a gear 6 is arranged at the bottom of the knob 1 and is used for being meshed with a spur gear 7 on the rotating shaft 2;

referring to fig. 2, a spur gear 7 is arranged at the top end of the rotating shaft 2, a convex block 8 is arranged on the side surface of the rotating shaft 2, and a threaded hole 9 is arranged on the bottom surface of the rotating shaft 2;

a threaded rod 10 is connected to an output shaft of the stepping motor 5;

the rectangular frame 4 is fixed on the lower surface of the gas stove shell 11, a partition plate 12 is arranged in the middle of the rectangular frame 4, a hole 13 is formed in the center of the partition plate 12, and a rectangular notch 14 is formed in the side surface of the hole 13;

referring to fig. 3 and 4, after assembly, the stepping motor 5 is fixed below a partition plate 12 in the rectangular frame 4, the threaded rod 10 is matched with a threaded hole 9 at the bottom of the rotating shaft 2, a spur gear 7 at the top of the rotating shaft 2 is meshed with a gear 6 at the bottom of the knob 1, and when the gas stove knob 1 is in an initial state, a convex block 8 on the rotating shaft 2 is just positioned at a gap 14 of a central hole 13 of the rectangular frame 4.

During the concrete implementation, 6 lower surfaces of the bottom gears of the knob 1 are provided with flat plates 15, and when the top spur gears 7 of the rotating shaft 2 move downwards, the spur gears 7 push down the gas stove knob 1 through the flat plates 15 at the bottom of the traction knob 1.

In specific implementation, the length of the rotating shaft 2 is such that when the threaded rod 10 is completely screwed into the threaded hole 9 at the bottom of the rotating shaft 2, the rotating shaft 2 just completes the pressing of the knob 1.

During specific implementation, the threaded rod 10 and the threaded hole 9 are in loose fit, namely after the threaded rod 10 is screwed into the threaded hole 9, the rotating shaft 2 can vertically rock for a distance not exceeding the pitch of one threaded rod 10.

Referring to fig. 5, when the automatic ignition control system is not needed to be intervened in use, power is stepped, 5 is powered off, and the user operation is not different from that of the automatic ignition control system which is not installed; when an automatic ignition control system is needed to intervene, when a gas stove needs to be ignited from an initial position, at the moment, a convex block 8 of a rotating shaft 2 is just positioned at a gap 14 of a central hole 13 of a middle partition plate 12 of a rectangular frame 4, because a threaded rod 10 is loosely matched with a threaded hole 9, the convex block 8 falls into the gap 14 at the moment, when a stepping motor 5 rotates, the rotating shaft 2 cannot rotate, the threaded rod 10 is screwed into the threaded hole 9 at the moment to pull down the rotating shaft 2, and further to realize the pressing-down action of a knob 1, when the convex block 8 is pulled down to the lower part of the middle partition plate 12, the constraint of the gap 14 disappears at the moment, the rotation of the stepping motor 5 drives the rotating shaft 2 to rotate, the adjustment of the opening degree of a gas stove assembly valve is realized, after the rotating shaft 2 rotates for a circle, the convex block 8, lug 8 is guided to in the breach 14, step motor 5 further antiport, axis of rotation 2 is lifted up, lug 8 resumes intermediate bottom 12 tops, the regulation to gas stove firepower size can be realized to step motor 5's rotation this moment, because 2 top spur gears 7 of axis of rotation are blocked by knob 1, when needs are closed a fire, step motor 5 antiport can not realize the motion of threaded rod 10 and screw hole 9, then step motor 5's antiport can realize closing a fire or knob 1 antiport ground purpose.

Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
