[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] This specific embodiment provides a rotary switch that solves the technical problem in the prior art where the knob and display screen are generally set separately, resulting in a relatively cramped overall panel.

[0019] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the following embodiments are not limited to those necessary for the solution of the utility model as described in the claims.

[0020] Reference Figures 1-8 This utility model provides a rotary switch, including a switch body 1. The body 1 is provided with a first knob 2, a touch screen 3, a first bracket 4, a knob bracket 5, a coaxial bracket 6, a coaxial fixing bracket 7, and a control board 8. The touch screen 3 is located in the middle of the first knob. Specifically, the first knob 2 is configured as a ring structure. The touch screen 3 is located inside the first knob 2, and the interior of the touch screen 3 is in contact with the inner sidewall of the first knob 2 so that the touch screen 3 and the first knob 2 can rotate relative to each other. The top of the touch screen 3 and the first knob 2 are flush. The control board 8 is electrically connected to the touch screen 3 to facilitate the control board 8 to receive signals from the touch screen. In order to reduce the rotation of the touch screen when the first knob 2 rotates, the touch screen 3 can always remain in the positive direction. The knob bracket 5 is rotatably mounted on the main body 1. The first knob 2 is fixedly connected to the knob bracket 5. When the first knob 2 is turned, it drives the knob bracket 5 to rotate. To ensure that the touch screen 3 can always be set in the correct orientation, the coaxial bracket 6 includes an inner ring 62 and an outer ring 61 that rotate relative to each other. That is, the outer ring 61 and the inner ring 62 can rotate relative to each other. The outer ring 61 is connected to the inner side of the knob bracket 5 by the first limiting component 18 so that the outer ring 61 rotates with the knob bracket 5. At the same time, the knob bracket 5 and the outer ring 61 are interference-fitted to fix the outer ring 61 to the knob bracket 5. The inner ring 62 is connected to the coaxial fixed bracket 7. The first bracket 4 is fixed to the body, and the inner ring 62 is fixed to the body. The first bracket 4 is fixedly connected to the coaxial fixed bracket 7. That is, the touch screen 3 is installed on the first bracket 4, and the control board 8 is installed on the coaxial fixed bracket 7. A second limiting component is provided between the two. In this way, the control board 8 can be stably installed on the coaxial fixed bracket 7. Since the coaxial fixed bracket 7 is fixedly connected to the first bracket 4, relative displacement between the control board 8 and the first bracket 4 is avoided, and relative displacement between the control board 8, the touch screen 3 and the first knob is reduced, ensuring the safety of the touch screen 3. The fixed connection can be that screws are simultaneously inserted into the coaxial fixed bracket 7 and the first bracket 4.

[0021] This design makes full use of the top position of the first knob 2, making the first knob 2 ring-shaped, and placing the touch screen 3 on top of the ring structure, thus integrating the touch screen 3 and the first knob 2 into one unit. To prevent the touch screen 3 from rotating with the first knob 2, the peripheral surface of the touch screen 3 contacts the side wall of the first knob 2. However, the rotation of the first knob 2 will not affect the touch screen 3. A coaxial bracket 6 is provided between the touch screen 3 and the first knob 2. The coaxial bracket 6 includes an inner ring 62 and an outer ring 61 that rotate relative to each other. The first knob 2 is connected to the outer ring 61 through the knob bracket 5, and the touch screen 3 is connected to the inner ring 62 through the first bracket 4 and the coaxial fixing bracket 7. Since the inner ring 62 and the outer ring 61 can rotate relative to each other, the touch screen 3 and the first knob 2 can be set coaxially, which can reduce the friction between the first knob 2 and the touch screen 3.

[0022] Furthermore, the first limiting component 18 includes a groove and a protrusion between the outer ring 61 and the knob bracket 5, such as Figure 2 As shown, the groove is provided on the inner ring 62, and the protrusion is provided on the knob bracket 5. At the same time, the protrusion can also prevent the outer ring 61 from moving downward, ensuring that the outer ring 61 and the knob bracket 5 rotate together. The second limiting component 19 is provided on the inner side wall of the inner ring 62, which facilitates cooperation with other components.

[0023] To further optimize the design, and to facilitate the mutual rotation of the outer ring 61 and the inner ring 62, the outer ring 61 is designed as a ring structure, and the inner ring 62 is also a ring structure. However, the outer circumference of the inner ring 62 includes a first connecting segment 621 and a second connecting segment 622 that are connected. The diameter of the first connecting segment 621 is larger than the diameter of the second connecting segment 622. The outer ring 61 is installed at the position of the second connecting segment 622, with one end flush with the stepped surface where the first connecting segment 621 and the second connecting segment 622 intersect, and the other end flush with the first end face of the second connecting segment 622. Since the outer ring 61 is fixedly connected to the knob bracket 5, and the outer circumference of the inner ring 62 is provided with a stepped surface, this can prevent the inner ring 62 from falling off, which would also affect the rotation of the outer ring 61.

[0024] To further optimize the solution, when the staff installs the control board 8 or its accessories, a connecting post 623 is provided on the end face of the inner ring 62 that is away from the outer ring 61. The connecting post 623 limits the position of the control board 8, thus limiting the position of the control board 8.

[0025] To further optimize the scheme, in order to identify the rotation of the first knob 2, a first encoder is set on the outer side of the outer ring 61. The first encoder is electrically connected to the control board 8, thereby feeding back the rotation of the first knob 2 to the control board 8, so that the control board 8 can control the equipment to make a corresponding response.

[0026] To further optimize the design and facilitate easy viewing of the switch position, a light guide strip 9 is also provided on the main body. The light guide strip 9 is electrically connected to the control board 8. A tri-color light is provided in the middle of the light guide strip 9. The tri-color light consists of three bulbs of the same color arranged side by side, which can present a light guide strip with a mixture of three colors. At the same time, the colors at both ends of the light guide strip 9 are relatively dark, while the brightness in the middle is relatively deep, so as to form natural diffused light and uniform brightness decay.

[0027] To further optimize the design and facilitate adjustments, multiple control buttons 10 are installed on the main body 1. The control buttons 10 are electrically connected to the control board 8, which facilitates control of the equipment's operating mode.

[0028] The design is further optimized. The main body 1 includes a shell and a smart panel. The smart panel is installed inside the shell. The first knob 2, touch screen 3, first bracket 4, knob bracket 5, coaxial bracket 6, and coaxial fixing bracket 7 are all part of the smart panel 17. The shell includes a bottom shell 11, a base 12, and a frame 13. The bottom shell 11 is installed in the wall, the base 12 is installed on the bottom shell 11, and the smart panel 17 is installed on the bottom shell 11. The frame 13 is magnetically connected to the base 12. This allows people to change the frame 13 according to their preferred color, avoiding the interference fit between protrusions and grooves used in existing technologies for fixation, and making it convenient for people to disassemble.

[0029] To further optimize the solution and enable voice control, the main body 1 also includes a voice module 14 and an amplifier box 16 installed inside the housing. The voice module 14 can recognize commands, and the amplifier box 16 is electrically connected to the voice module 14 and converts the commands into voice. At the same time, the amplifier box 16 is electrically connected to the control board 8, which facilitates the control board 8 to control the device for adjustment.
