For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0027] Refer to the following Figure 1-Figure 7The structure of a combination knob according to some embodiments of the present application is described.

[0028] A structure of a combination knob is provided. The combination knob is mounted on a knob hole 2 of an electrical appliance housing 1 and includes a knob 3, a knob base 4, an encoder 5, a PCB control board 6, a button 7, an LED bracket 8, an electronic screen 9, a light ring 10, a touch switch 26, and a light 27.

[0029] The encoder 5 is soldered to the PCB control board 6. The knob base 4 is connected to the encoder outer ring 5a via a first snap-fit ​​structure 11, which consists of a first protrusion 12 on the knob base 4 and a first groove 13 on the encoder outer ring 5a. A second protrusion 14 on the knob base 4 engages with a second groove 15 on the encoder outer ring 5a, preventing the knob base 4 and the encoder outer ring 5a from rotating relative to each other. The knob 3 is connected to the knob base 4 via a second snap-fit ​​structure 16, which consists of a first clip 17 on the bottom of the knob 3 and a step 18 on the outer wall of the knob base 4. A third protrusion 19 on the outer wall of the knob base 4 engages with a third groove 20 on the inner wall of the knob 3, preventing the knob base 4 and the knob 3 from rotating relative to each other. The encoder outer ring 5a is a rotatable structure. Therefore, when the combination knob is assembled, the knob base 4 can be rotated by rotating the knob 3, which in turn drives the encoder outer ring 5a to rotate, generating a signal that is input into the PCB control board 6. By compiling a program as needed, the function of controlling different modes or gears of the machine by rotating the knob 3 can be realized.

[0030] The button 7 is connected to the LED bracket 8 via a third snap-fit ​​structure 21, which is composed of a raised ring 22 at the bottom of the button 7 and a second snap 23 on the side wall of the LED bracket 8. The LED bracket 8 is sleeved within the encoder inner ring 3b, which is a non-rotatable structure. The first axial protrusion 24 of the encoder inner ring 3b matches the second axial protrusion 25 below the LED bracket 8, so that the LED bracket 8 can only move axially. The touch switch 26 is welded to the PCB control board 6 and is located opposite the center of the LED bracket 8. When the combination knob is assembled, you only need to press the button 7 to force the LED bracket 8 downward, and then touch the touch switch 26 to start or shut down the machine, realizing the function of turning the machine on and off by pressing the button 7.

[0031] A limiting slot 28 is provided on the LED bracket 8, and the electronic screen 9 is snapped onto the limiting slot 28 and is located below the button 7. There is excess space between the LED bracket 8 and the PCB control board 6, and a guide block 29 is provided. The guide block 29 is provided with a first through hole 30 and a second through hole 31, and the first through hole 30 is passed through by the touch switch 26. A metal wire extends from the bottom of the electronic screen 9, passes through the LED bracket 8 and the second through hole 31 of the guide block 29, and is welded to the PCB control board 6. The metal wire receives instructions from the PCB control board 6, and the electronic screen 9 displays information. The button 7 is made of a transparent material, and the display of the electronic screen 9 can be seen from the outside through the button 7, realizing the function of the machine's electronic display.

[0032] The inner edge of the light ring 10 is raised, and the outer edge forms a circular step. The bottom of the light ring 10 is supported by the PCB control board 6, and the inner edge of the light ring 10 protrudes from the knob hole 2. Lamp 27 is soldered to the PCB control board 6, receiving commands and emitting different light levels based on the commands. The light ring 10 is made of a translucent material. The light emitted by lamp 27 is refracted and scattered by the light ring 10, making it visible outside the combination knob, thus conveying information through the light color while creating an aesthetic effect.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
