The first light-transmitting element 2 covers the light-emitting elements 6. Multiple function icons 7 are arranged in a ring on the first light-transmitting element 2. Detection triggers 4, light-emitting elements 6, and function icons 7 are correspondingly arranged. When a light-emitting element 6 emits light, it acts on the corresponding function icon 7, which is then displayed through the display window 3. When the knob rotation mechanism rotates to the corresponding position, the corresponding detection trigger 4 acts on the detection component 5, causing the control panel 1 to control the corresponding light-emitting element 6 to emit light and act on the corresponding function icon 7. The display window 3 also moves to the position of the corresponding function icon 7, allowing the corresponding function icon 7 to be displayed through the display window 3. Rotating the knob mechanism adjusts the speed. The function icons 7 (i.e., menu functions) include stir-frying, steaming, soup making, simmering, low heat, keep warm, and slow cooking.

[0030] The knob fixing mechanism includes a housing 8 and a second light-transmitting element 9 disposed on the surface of the housing 8. The housing 8 is rotatably mounted on the knob rotation mechanism. The second light-transmitting element 9 covers the display window 3 and the detection trigger element 4. Multiple indicator marks are distributed in a ring on the second light-transmitting element 9. The function mark 7 on the display window 3 can be seen through the second light-transmitting element 9.

[0031] The first light-transmitting element 2 is a transparent sticker, which is attached to the bracket 19. The second light-transmitting element 9 is a semi-transparent sticker, which is attached to the surface of the outer shell 8.

[0032] Multiple mounting slots 10 are distributed in a ring on the outer casing 8, and the detection trigger 4 is installed in the mounting slot 10.

[0033] The detection trigger 4 is a magnet, the detection component 5 is a Hall sensor, the light-emitting component 6 is an LED bead, and one Hall sensor is set. The Hall sensor senses the position of the magnet to realize the precise function display and function adjustment of the knob. Multiple magnets trigger one Hall sensor to control the control board 1 to adjust the display and send control signals to the smoke machine.

[0034] It also includes a power supply component 11 and a power board 12 mounted on the knob fixing mechanism. The power supply component 11 and the power board 12 are electrically connected to the control board 1. The power board 12 is provided with a charging port 13 for connecting to an external charging terminal. The knob fixing mechanism is provided with a clearance hole 14 corresponding to the position of the charging port 13. The power supply component 11 is a battery that can power the detection component 5 and the light-emitting component 6. The charging port 13 can charge the power supply component 11.

[0035] Alternatively, the inner shell assembly is provided with a lead wire hole 15, through which the wire from the control board 1 passes and connects to the pulse box of the stove; the control board 1 is provided with a communication module; the communication module is used in conjunction with the Internet of Things to provide information reminders for the stove and range hood matched with the knob to turn on, off, or be left unattended for a long time through the material network; the communication module can also be connected to the pulse box of the stove to realize information alarm and control gas shut-off through the wireless data transmission function (such as Wi-Fi) of the pulse box.

[0036] In this embodiment, the communication module is a transmitting module for sending signals to the range hood. The range hood is equipped with a receiving module, and the transmitting module is communicatively connected to the receiving module. When the knob adjusts the heat level, it sends a corresponding signal to the receiving module of the range hood through the transmitting module. After receiving the corresponding signal, the receiving module of the range hood controls the exhaust intensity of the range hood through its built-in control board to match the exhaust intensity of the range hood with the heat level of the gas stove, thereby realizing the linkage function between the range hood and the gas stove. The transmitting module and the receiving module can be connected by a line or a wireless network. The above structure is prior art and will not be described in detail here.

[0037] It also includes a base 16 for fixing to the cooktop panel. The knob body a is mounted on the base 16 and moves up and down. The knob body a is provided with a fastener 17. The lower part of the fastener 17 is provided with an elastic element, which is a spring. The lower end of the elastic element abuts against the base 16. When the knob body a is pressed down, it compresses the elastic element. When the knob body a is released from the press, the knob body a returns to its original position under the elastic force of the elastic element.

[0038] The rotating shaft 20 of the knob body a is connected to the valve body of the stove. The knob in this embodiment is the same as the traditional knob. Before rotating the outer shell assembly, the knob body a needs to be pressed to unlock the outer shell assembly so that the outer shell assembly can be rotated. The knob in this embodiment can be used for precise flame control menu displays with 180-degree axis and 270-degree axis on the market.

[0039] The knob fixing mechanism includes an inner shell 18 and a bracket 19. The bracket 19 is fixed on the inner shell 18.
