Technical Field
The utility model belongs to the technical field of show, specifically relate to a hidden interface panel subassembly of oral cleaning utensil to and manufacturing method thereof.
Background
There is typically a user interface panel on the handle of the oral cleaning implement through which indicia associated with various conditions are provided to the user, e.g., the interface panel of the oral cleaning implement displays different cleaning modes or brush head speeds and amplitudes, and power levels, etc. through the indicia.
Some oral cleaning implements have a hidden interface panel that is completely blank and does not display any indicia when the oral cleaning implement is closed, and illuminated indicia are visible on the interface panel when the oral cleaning implement is activated, which increases the appeal and aesthetics of the oral cleaning implement.
As shown in figure 1, a sectional structure schematic diagram of a hidden interface panel, the panel comprises a transparent plastic bottom plate 1, a dark first coating layer 3 covering the surface of the plastic bottom plate 1 and a light second coating layer 2 covering the first coating layer 3, a mark 4 area is reserved on the dark first coating layer, the mark area is not coated with the dark first coating layer 3, an LED lamp body 5 is arranged on the inner side of the plastic bottom plate 1, when the LED lamp body 5 emits light, the light is carried through the mark area, the light shadow same as the mark can be observed on the outer side of the panel, and the state of the oral cleaning appliance is shown. To prevent the problem of light channeling, baffle structures are provided around each LED that confine the light generated by each LED to its associated front panel indicia.
The hidden interface panel has the disadvantages that the hidden interface panel also has the problems of light leakage and too bright and dazzling LED light, when the LED lamp body 5 under a certain mark emits light, light shadow with certain brightness also appears in the adjacent mark area, so that the marks in the adjacent areas emit light to cause user confusion, and the direct light of the LED lamp is too bright and dazzling, and one solution is to improve the structure of the light source baffle plate, but a new structure, a new process and cost are inevitably increased. Meanwhile, as the light-colored second coating 2 covers the mark area, in order to display the mark area, the second coating 2 needs to be transparent, so that the color of the handle shell is presented by the first coating 3, the first coating 3 needs to have the effects of shading and presenting the visual color of the handle, and the color and the material of the first coating are limited, so that the color which is liked by various users cannot be presented.
SUMMERY OF THE UTILITY MODEL
To the technical problem who exists among the prior art, the utility model aims at providing a hidden interface panel subassembly of oral cavity cleaning appliance, can solve the mark light leak or the too bright problem of LED light among the user hidden interface panel of oral cavity cleaning appliance.

wherein the second layer of paint is provided with a laser engraved area defining indicia representing a plurality of states of the oral cleaning implement, the laser engraved area extending to an outer surface of the panel housing, light generated by the light emitting element being visible to a user through the first layer of paint, the panel housing and the laser engraved area.
The technical effect of the technical scheme is that the first coating layer on the inner surface of the panel shell is used, light generated by the light-emitting element firstly passes through the first coating layer, the light can be uniformly dispersed in the first coating layer, the light shadow of the lighted associated mark is more uniform and softer, the dazzling problem of the light is reduced, meanwhile, the first coating layer enables the light scattered to the adjacent mark to be weakened to the extent that the light is not seen by a user, the user is prevented from confusing which mode is actually selected, and the light source baffle is not required to be structurally improved and set.
In an example of the technical solution, the first coating layer is a light diffusion coating, so that light leakage can be avoided and the mark corresponding to the unselected state can be illuminated.
The light diffusion coating is a coating with a high refractive index, and the light diffusion coating can emit directional light rays to the associated mark from the light-emitting element, and the directional light rays can penetrate through the light diffusion coating because the directional light rays are perpendicular to the light diffusion coating or have small incident angles, so that the directional light rays are more uniform; by refracting and reflecting scattered light rays emitted to adjacent marks, light leakage can be avoided, so that the adjacent marks are also illuminated or partially illuminated, the actually illuminated marks are not easily confused by a user, the LED light is softer, and the manufacturing process is simple.
In one example of the technical scheme, a color development layer enabling the panel shell to present required visual colors is further covered on the outer surface of the second coating layer, and the laser etching area extends through the color development layer.
Furthermore, the color development layer is an electroplated layer and/or a pigment layer. The electroplated layer makes the panel shell of the oral cleaning appliance present a metallic luster, and the pigment layer makes the panel shell present a required visual color. The color development layer enables the color selectivity of the panel shell to be wide, reduces the requirement on the second coating layer, only needs the second coating layer to block light, and has no requirement on appearance color.
Further, the color developing layer may have the same color as or a color close to that of the first coating layer. Because the two are in the same or close colors, when the light-emitting element is not illuminated, the visual colors of the mark and the panel shell are consistent, and the effect of better hiding the mark is achieved.
In an example of the technical scheme, the protective coating layer is covered on the color development layer, and the protective coating layer is a clear coating layer made of polyurethane or similar materials and used for protecting the panel from abrasion.
In one example of the technical scheme, the color development layer is not needed, the color of the second coating layer is used as the panel shell to present the required visual color, and the protective coating layer is coated on the second coating layer in a covering mode. Because there is no color development layer, the requirement for the second coating layer is higher, namely, the requirement for shading is needed, and the appearance color of the handle is also needed. The second coating layer may have the same color or a color close to that of the first coating layer. Because the two are in the same or close colors, when the light-emitting element is not illuminated, the visual colors of the mark and the panel shell are consistent, and the effect of better hiding the mark is achieved.
In an example of the technical solution, the color development layer may also be an electroplated layer and a pigment layer, so that the bottom color of the pigment layer is the color of the electroplated layer, thereby enabling the panel housing to present a color with a metal color.
In one example of this solution, the light emitting elements are LEDs, one for each mark.
