[0031] As described in the background technology, a gas stove is a device that uses gas for cooking. It is usually composed of a gas nozzle, an ignition device, a control valve and a burner. The working principle of the gas stove is to adjust the gas flow rate through a control valve so that the gas is mixed with air and then burned in the burner to generate heat energy for heating food. During the use of the gas stove, leaving the gas stove without extinguishing the flame is the main cause of fire. In order to enable the gas stove to automatically extinguish the flame when a problem occurs, most existing gas stoves will choose to add a gas alarm and a gas shut-off valve as safety devices of the gas stove. When the gas alarm detects a gas leak, it will control the gas shut-off valve to close to extinguish the gas stove. However, the above method requires the modification of the gas pipeline, which is not only costly, but also time-consuming and laborious to install.

[0032] See also Figures 1 to 4As shown, in order to solve the above-mentioned problem, according to one aspect of the present application, an embodiment of the present application provides a gas stove safety device, which is used to turn off the ignition knob 50 of the gas stove. The gas stove safety device comprises: a main body 10, a knob driving part 20 and an electromagnetic driving part 30, wherein the knob driving part 20 is movably installed on the main body 10, and the knob driving part 20 has a driving state connected to the ignition knob 50 and a avoidance state for avoiding the ignition knob 50. In the driving state, the knob driving part 20 can drive the ignition knob 50 to turn off the ignition knob 50; the electromagnetic driving part 30 is arranged on the main body 10, and the knob driving part 20 can switch from the avoidance state to the driving state under the drive of the electromagnetic driving part 30. The gas stove safety device provided in the present embodiment is achieved by movably mounting the knob driving part 20 on the main body 10, and arranging the electromagnetic driving part 30 on the main body 10, so that the knob driving part 20 provided in the present embodiment can be driven by the electromagnetic driving part 30 to quickly switch from the avoidance state to the driving state when a problem occurs with the gas stove, so that the ignition knob 50 can be turned off in time under the drive of the knob driving part 20. At the same time, since the gas stove safety device provided in the present embodiment realizes the shutdown of the gas stove through the ignition knob 50 on the gas stove, there is no need to modify the gas pipeline, which is not only low in cost, but also convenient to install and saves time and effort.

[0033] In an optional embodiment, the electromagnetic driving part 30 provided in this embodiment is an electromagnetic push rod. Since the response speed of the electromagnetic push rod is relatively fast, the knob driving part 20 provided in this embodiment can be quickly switched from the avoidance state to the driving state under the drive of the electromagnetic push rod.

[0034] In a specific embodiment, after the electromagnetic push rod provided in this embodiment is powered on, the output end of the electromagnetic push rod can extend a preset distance in the direction close to the knob driving part 20, so that the knob driving part 20 can switch from the avoidance state to the driving state. After the electromagnetic push rod is powered off, the output end of the electromagnetic push rod can automatically reset to avoid the knob driving part 20. Of course, in other embodiments, the output end of the electromagnetic push rod provided in this embodiment can also be pivotally connected to the knob driving part 20, so that the knob driving part 20 can switch between the avoidance state and the driving state under the drive of the electromagnetic push rod.

[0035] In order to enable the knob driving unit 20 provided in this embodiment to maintain the avoidance state without being acted upon by external forces, the gas stove safety device in this embodiment further includes an elastic reset unit 40, which is arranged on the main body 10 and connected to the knob driving unit 20, and is used to apply an elastic force to the knob driving unit 20 in a direction away from the ignition knob 50, so that the knob driving unit 20 can maintain the avoidance state without being acted upon by external forces. By arranging the elastic reset unit 40 on the main body 10 provided in this embodiment and connecting the elastic reset unit 40 to the knob driving unit 20, the knob driving unit 20 provided in this embodiment can maintain the avoidance state by the elastic force applied by the elastic reset unit 40 without being acted upon by external forces. At the same time, by arranging the knob driving unit 20 provided in this embodiment to maintain the avoidance state without being acted upon by external forces, the gas stove safety device can be prevented from affecting the normal use of the ignition knob 50.

[0036] In an optional embodiment, the elastic reset portion 40 provided in this embodiment is a tension spring. Of course, in other embodiments, the elastic reset portion 40 provided in this embodiment can also be a compression spring or other device that can apply an elastic force to the knob drive portion 20 away from the ignition knob 50.

When the knob driving unit 20 is in a driving state, the knob driving wheel 23 can abut against the ignition knob 50 and drive the ignition knob 50. By movably mounting the driving bracket 21 provided in the present embodiment on the main body 10, arranging the driving motor 22 on the driving bracket 21, rotatably mounting the knob driving wheel 23 on the driving bracket 21, and drivingly connecting the driving motor 22 with the knob driving wheel 23, the knob driving wheel 23 provided in the present embodiment can rotate under the drive of the driving motor 22. When the knob driving part 20 provided in the present embodiment is used to close the ignition knob 50, it is only necessary to set the knob driving part 20 provided in the present embodiment to a driving state. At this time, the knob driving wheel 23 can abut against the ignition knob 50. When the knob driving wheel 23 is fully abutted against the ignition knob 50, the knob driving wheel 23 can be driven by the driving motor 22 to rotate in a preset direction. Since the knob driving wheel 23 abuts against the ignition knob 50, the rotating knob driving wheel 23 can drive the ignition knob 50 to rotate in the closing direction, thereby realizing the closing of the gas stove.
