[0028] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0029] The present utility model proposes a knob switch 10 with a light display. By connecting a light guide column 121 with a knob cover 11, a transmission passage is formed between the light guide column 121 and the lamp group, and the light of the lamp group is transmitted out from the light-emitting surface of the light guide column 121. The indicator light can rotate with the rotation of the knob 111, and the current gear position can be displayed intuitively and clearly.

[0030] like Figures 1 to 6 As shown, the knob switch 10 with light display provided by the present invention includes: a knob cover 11, which is made of an opaque material; a light panel 13 with an indicator light group 131, which can display light according to the power supply status and different gear positions; a potentiometer 14 with a rotating shaft core 141, which can be turned on or off or the gear position can be adjusted by rotating the rotating shaft core 141; and a light guide 12 with a light-transmitting function, one end of which is a light guide column 121 made of a light-transmitting material. The light panel 13 is disposed on the potentiometer 14 and is electrically connected to the potentiometer 14. The light panel 13 can be powered by a power supply connected to the potentiometer 14. The light guide 12 is disposed on the light panel 13, and the light guide column 121 is disposed directly above the indicator light group 131. The light emitted by the indicator light group 131 passes through the light receiving surface of the light guide column 121 and the light emitted by the indicator light group 131 is always aligned with the light receiving surface of the light guide column 121. The light emitting surface of the light guide column 121 is fixedly connected to the front end surface of the knob cover 11, forming an indicator light on the rotating cover. The rear end surface of the knob cover 11 is connected to the rotating shaft core 141, which drives the rotating shaft core 141 to rotate to adjust the potentiometer 14.

[0031] Specifically, if Figure 3As shown, the light guide 12 also includes an opaque base 122, and the light guide column 121 is arranged on the base 122; there is a through hole in the middle position of the base 122, and the light receiving surface of the light guide column 121 is assembled in the through hole of the base 122 by interference fit; the base 122 is assembled on the light board 13 by a fixed connection. In addition, in order to fully concentrate the light on the light receiving surface of the light guide column 121, a device or texture pattern that is conducive to light concentration can also be provided on the inner side of the base 122, such as a focusing ring or lens or other patterns or elements that can concentrate light. The light emitted by the indicator light group 131 on the light board 13 can diffuse outward through the light guide column 121.

[0032] like Figure 4 As shown, the light board 13 is provided with a through hole 132 on the side away from the indicator light group 131. The diameter of the through hole 132 is the same as the diameter of the rotating shaft core 141. The rotating shaft core 141 can pass through the through hole 132 and is connected to the through hole 132 by interference fit. At the same time, in order to facilitate the fixing of the light board 13 to the potentiometer 14, a limiting groove 133 is provided on the back side of the light board 13 away from the through hole 132. Figure 5 As shown, the potentiometer 14 is provided with a positioning post 142 inserted into the limiting groove 133. When fixedly connected, the rotating shaft core 141 passes through the through hole 132, and the limiting groove 133 is inserted into the positioning post 142, thereby fixing the light board 13 and the potentiometer 14.

[0033] In this embodiment, when the light panel 13 is connected to a power source through the potentiometer 14 and powered on, the indicator light group 131 lights up. The indicator light group 131 is a plurality of LED light groups of the same color or the indicator light group 131 is a plurality of LED light groups of different colors. When the indicator light group 131 is a plurality of LED light groups of the same color, the indicator light group 131 can be set so that all LED light groups are all lit after power is turned on, and the brightness of the LED light group will not change when the gear is adjusted; or it can be set so that only one LED light is lit after power is turned on, indicating that it is currently in a working state, and the brightness of the LED light group changes as the gear is adjusted. When the indicator light group 131 is a plurality of LED light groups of different colors, the indicator light group 131 can be set to use LED lights of different colors to indicate the current working state and to indicate different gears.

[0034] like Figure 6As shown, the knob cover 11 includes a knob 111 and a knob ring 112 that is interference-fitted with the knob 111. The knob 111 and the knob ring 112 are both made of opaque materials to reduce light loss caused by the divergence of light toward the outer side of the knob cover 11. An opening 113 is provided on the front end face of the knob 111. The light-emitting surface of the light guide column 121 can be installed in the opening 113. The light-emitting surface of the light guide column 121 is in the same plane as the front end face of the knob 111 and is fixedly connected to the knob 111. Therefore, when the knob 111 is rotated, the indicator light formed by the light guide column 121 can rotate together, and there is always a lighting display function. A straight slot is provided at the top of the rotating shaft core 141, and a mounting shaft core is provided at the rear end of the knob 111. The mounting shaft core may be E-shaped and can be sleeved onto the rotating shaft core 141, with the middle portion of the mounting shaft core engaging the straight slot of the rotating shaft core 141. The mounting shaft core and the rotating shaft core 141 are fixedly connected by an interference fit, so that rotating the knob 111 can drive the rotating shaft core 141 to rotate.

[0035] like Figure 7 As shown, the present invention also provides a humidifier, which includes at least a bottom shell 20, a water tank 30 arranged above the bottom shell 20, and a mist outlet 40 is provided at the top of the water tank 30, and the outer shell of the bottom shell 20 is provided with a knob switch 10 with light display provided by the present invention.

[0036] When the humidifier is turned on by turning on the knob 10, the power oscillator plate of the bottom housing 20 begins to operate, oscillating the water in the water tank 30 above the bottom housing 20 to produce mist, which is then discharged through the mist outlet 40 at the top of the water tank 30. During operation, the indicator light on the knob 10 illuminates, and the indicator light rotates with the rotation of the knob 111, providing a clear and intuitive display of the current gear position.

[0037] The present invention provides a knob switch 10 and a humidifier with light display, which are connected to a rotating cover plate via a light guide 12. Light can be displayed on the rotating cover plate, and the light can not only prompt the switching process of the power supply; but also the indicator light can rotate with the rotation of the knob 111, and can intuitively and clearly display the current gear position. Especially when used at night, it is easier to find the position of the knob 111 and adjust the gear position, which is convenient for users to adjust the gear position.

[0038] Although preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concepts. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
