Description

Technical Field

[0001] This utility model belongs to the field of drainage valve technology, and specifically relates to a cover plate illuminated button structure. Background Technology

[0002] Smart toilets are becoming increasingly popular, but they have many functions, so some buttons need to be set up. When the environment is dark or when using them at night, users may not be able to quickly and accurately find the corresponding buttons to operate the relevant functions. Summary of the Invention

[0003] To overcome the shortcomings of the prior art described in the background section, this utility model provides a cover plate light-emitting button structure, including a housing, a cover body, a PCB board, and a light guide. The PCB board is mounted on the housing and has multiple LED light emitters. The light guide is fixed to the PCB board so that the light generated by the LED light emitters is guided out through the light guide. The cover body is fixed to the housing by a snap-fit ​​structure and has at least one elongated through hole. The light guide can pass through the through hole to achieve light emission from the outside of the cover body.

[0004] Furthermore, the cover has two through holes in the transverse direction.

[0005] Furthermore, the operation buttons of the cover are located on the cover body, and the two through holes are located on the upper and lower sides of the operation buttons.

[0006] Furthermore, the light guide consists of two light guide sheets and a fixing strip connecting the two light guide sheets.

[0007] Furthermore, one end face of the light guide sheet abuts against the LED light emitter, and the other end face passes through the through hole, with its thickness and length matching the through hole.

[0008] Compared with the prior art, the technical solution adopted in this utility model has the following advantages: By setting light guides on the upper and lower sides of the control buttons on the cover, not only is a night-light illumination effect achieved, but the control buttons on the cover are also clearly visible at night, allowing users to quickly and accurately perform relevant functions without accidental operation.

[0009] Figure 1 This is an overall schematic diagram of the cover plate illuminated button structure of this utility model; Figure 2 This is an exploded view of the cover plate illuminated button structure of this utility model; Figure 3 This is a front view of the cover of the cover plate illuminated button structure of this utility model. Detailed Implementation

[0010] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0011] like Figure 1-3 As shown, the cover plate light-emitting button structure of this utility model includes a housing 1, a cover 2, a PCB board 3, and a light guide 4. The housing 1 is recessed to form a cavity. The PCB board 3 is installed in the cavity of the housing 1. The PCB board 3 is provided with multiple LED light emitters 30. The PCB board is used to control the light emission of the LEDs. The light guide 4 is fixed on the PCB board 3 so that the light generated by the LED light emitters 30 is guided out through the light guide 4. Specifically, the light guide 4 is composed of two light guide sheets 40 and a fixing strip 41 connecting the two light guide sheets. One end face of the light guide sheet 40 abuts against the LED light emitter, so that the light guiding effect of the light guide sheet 40 is optimal. In this embodiment, two rows of LED light emitters 30 are arranged on the PCB board 3 so that both light guide sheets 40 can guide the light. The cover 2 has two slender through holes 20 in the transverse direction. The cover 2 is fixed to the housing 1 by a snap-fit ​​structure. At this time, the other end face of the light guide 40 passes through the through hole 20 to realize the light emission from the outside of the cover 2. The thickness and length of the light guide 40 are adapted to the through hole 20, making the product aesthetically pleasing.

[0012] The operation button 21 of the cover is set on the cover body 2, and the two through holes 20 on the cover body 2 are set on the upper and lower sides of the operation button 21, so that when the light guide sheet 40 shines through the through hole 20, all the buttons can be clearly seen at night, so that users can quickly and accurately perform related functions without misoperation.

[0013] The assembly sequence of the cover plate light-emitting button structure of this utility model is as follows: first, the PCB board 3 is installed in the cavity of the housing 1, then the light guide 4 is placed on the PCB board 3, then the PCB board 3 and the light guide 4 are fixed on the housing 1 by potting glue, and finally the through hole 20 of the cover 2 is aligned with the light guide 40 and installed, and the cover 2 and the housing 1 are snapped together.

[0014] The above provides a detailed description of the cover plate illuminated button structure provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
