Description

Technical Field

[0001] The present application relates to the technical field of gas stove shutdown devices, and more specifically, to an automatic shutdown device. Background Art

[0002] As a commonly used cooking utensil, the gas stove is closely related to our life. Whether it is boiling water or cooking, the gas stove is indispensable. Since the knob switch of the gas stove is mainly manual operation, during the kitchen cooking process, people often encounter situations where they are too busy or have to leave the cooking scene due to urgent matters. At this time, they will forget to turn off the gas stove, thus posing potential safety hazards such as overheating and fire. Therefore, universities and various research institutions have added a dry-burning prevention function inside the gas stove. The main method is to use control devices such as single-chip microcomputers and PLCs, combined with technologies such as pressure sensors, temperature detection, thermocouples, and solenoid valves, to develop corresponding software programs to transform the gas stove, which can achieve functions such as automatic ignition, timed shutdown, firepower adjustment, dry-burning prevention, and empty-burning prevention. In order to be more intelligent and display various parameters through a display screen, information such as the size of the fire, the ignition time, and the timed shutdown time can be observed through the display screen. However, a problem has been overlooked, that is, when the gas stove shutdown device is in use, during ignition and shutdown, the human-machine interface (display screen) will rotate together with the ignition knob, which brings inconvenience to people during use and does not conform to ergonomics.

[0003] The prior art document with the publication number CN 219976504 U provides an automatic shutdown device. This device realizes that when the ignition rotary cover, ignition transmission part, ignition rod sleeve, and ignition rod rotate synchronously together, the base, motor base, lower-layer circuit board, and upper-layer circuit board remain stationary. Thus, during the use of the gas stove shutdown device, whether during ignition and automatic shutdown, the human-machine interface (display screen) and the ignition rotary cover do not rotate together, which conforms to ergonomics and meets the needs of people's high-quality life.

[0004] Although the above prior art solution can achieve the relevant beneficial effects through the structure of the prior art, there are still the following defects: the structure for keeping the display screen interface from deflecting is relatively complex, and it will cause inconvenience in maintenance once it is damaged.

[0005] In view of this, we propose an automatic shutdown device. Utility Model Content

[0030] The present application will be further described in detail below with reference to the accompanying drawings of the specification.

[0031] An automatic flameout device includes an ignition rotary cover 1, a base 2, an ignition rod 3, a transparent cover 4 and a display screen 5. The ignition rotary cover 1 includes a rotary cover 11 and a top cover 12 detachably connected to the rotary cover 11. The transparent cover 4 is fixed on the top cover 12. A detachable support rod 53 is rotatably connected between the non-display surface of the display screen 5 and the rotary cover 11. A plurality of second magnets 51 are annularly distributed on the non-display surface of the display screen 5 with the support rod 53 as the axis. A plurality of first magnets 21 magnetically attracted to and corresponding to the second magnets 51 are annularly distributed on the base 2.

[0032] Referring to Figures 1-7 , after the base 2 is fixed on the panel of the gas stove, under the magnetic attraction of the first magnet 21 and the second magnet 51, the display screen 5 is rotatably arranged in the rotary cover 11 with the support rod 53 as the fulcrum. Therefore, when the ignition rotary cover 1 and the ignition rod 3 rotate, under the magnetic attraction, the display screen 5 will not rotate with the rotary cover 11. And through the detachable connection between the top cover 12 and the rotary cover 11, and the detachable connection of the support rod 53, it is convenient for disassembly and maintenance, and the overall structure is simpler and more convenient for maintenance.

[0033] A plurality of connecting rods 52 annularly distributed with the connecting rod 52 are fixed on the lower non-display surface of the display screen 5. The second magnet 51 is fixed at the lower end of the connecting rod 52. The second magnet 51 is close to the first magnet 21 and does not contact the lower surface of the rotary cover 11.

[0034] Referring to Figure 2 and Figure 6 , the connecting rod 52 can make the second magnet 51 close to the first magnet 21, improving the magnetic attraction intensity. And the second magnet 51 does not contact the rotary cover 11, so that no frictional force is generated between the second magnet 51 and the rotary cover 11 when the rotary cover 11 rotates, preventing the second magnet 51 from being driven to rotate under the action of the frictional force when the rotary cover 11 rotates.

[0035] The support rod 53 includes a ridge rod 531 rotatably connected to the non-display surface of the display screen 5 and a sleeve 532 adapted to the ridge rod 531. Third magnets 533 magnetically attracted to each other are fixed at the lower ends of the sleeve 532 and the ridge rod 531.

[0036] Referring to Figure 2 and Figure 6 andFigure 7 , through the sliding insertion fit between the prism rod 531 and the sleeve 532, it is convenient for the disassembly and assembly of the support rod 53. At the same time, through the magnetic attraction of the two third magnets 533, it is convenient to fix the prism rod 531 in the sleeve 532.

[0037] Bearings 54 are connected between the prism rod 531 and the display screen 5, and between the sleeve 532 and the rotary cover 11.

[0038] Refer to Figure 5 , the prism rod 531 is fixed to the inner ring of the upper bearing 54, the outer ring of the upper bearing 54 is fixed to the bottom of the display screen 5, the sleeve 532 is fixed to the inner ring of the lower bearing 54, and the outer ring of the lower bearing 54 is coaxially fixed in the rotary cover 11, so as to realize the rotational connection between the support rod 53 and the rotary cover 11 and the display screen 5 through the two bearings 54.

[0039] The rotary cover 11 is threadedly connected to the top cover 12.

[0040] Refer to Figure 2 and Figure 4 , through the threaded connection between the rotary cover 11 and the top cover 12, it is convenient for the disassembly of the top cover 12.

[0041] Working principle: The base 2 is fixed on the panel of the gas stove, and the display screen 5 faces the operator. When the operator rotates the ignition rotary cover 1 and the ignition rod 3, under the action of magnetic attraction, the first magnet 21 and the second magnet 51 cause the rotary cover 11 to rotate around the support rod 53 and the ignition rod 3. At the same time, under the action of magnetic attraction, the display screen 5 will not rotate with the rotary cover 11 to ensure that the display screen 5 always faces the operator. When the display screen 5 needs to be maintained, the top cover 12 is screwed off, and then the display screen 5 is pulled upward to separate the two third magnets 533.
