Implementation

The specific implementation of the present invention is described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

Example 1:

Referring to Figures 1 to 3, the present embodiment provides a luminous ceramic cup, including a cup body 1 and a cup cover 2, the cup body 1 includes an inner cup body 11, a light guide layer 12 and an outer cup body 13 nested in sequence, and the outer cup body 13 is made of translucent ceramic; the light guide layer 12 is provided with a plurality of scattered light points, the top surface where the light guide layer 12 and the cup cover 2 abut against each other is the light incident surface, and the outer side surface where the light guide layer 12 and the outer cup body 13 abut against each other is the light exit surface; a luminous body 21 is provided around the light guide layer 12 at the bottom of the cup cover 2, and the light emitted by the luminous body 21 enters the interior of the light guide layer 12 from the light incident surface, is scattered through the scattered light points, and is emitted from the light exit surface, so as to be uniformly projected on the outer cup body 13, thereby converting a point-shaped or strip-shaped light source into a surface light source, thereby enhancing the luminous effect of the ceramic cup. In the present embodiment, the luminous body 21 is arranged at the bottom of the cup cover 2, and the light guide layer 12 is arranged in the cup body 1, so as to realize the split design of the light-emitting device, thereby facilitating cleaning or replacement of components, and having higher practicality and convenience.

Referring to Figures 3 and 5, a number of scattered light spots are engraved on the light guide layer 12 by laser. If the light guide layer 12 is directly bonded to the inner cup body 11 and the outer cup body 13 with ordinary glue, the liquid glue will enter the scattered light spots, thereby blocking the scattered light spots and preventing the light from being emitted, which ultimately affects the light scattering effect, resulting in poor luminous effect of the outer cup body 13 and an abnormal phenomenon of local dark areas. In order to solve this problem, in this embodiment, a protective film 14 is provided between the light guide layer 12 and the inner cup body 11 and the outer cup body 13. The protective film 14 is bonded to the light guide layer 12 by a first adhesive 141, and is bonded to the inner cup body 11 or the outer cup body 13 by a second adhesive 142. The first adhesive 141 and the protective film 14 together constitute a protective barrier that isolates the light guide layer 12 from the second adhesive 142, thereby preventing the second adhesive 142 from directly contacting the light guide layer 12 and blocking the scattered light spots.

Referring to Figures 3 and 5, specifically, the protective film 14 is preferably a PET film, the first adhesive 141 is a polyurethane adhesive, and the second adhesive 142 is an epoxy resin glue. The polyurethane adhesive does not immediately have a high bonding strength during bonding, and it needs to be cured. The so-called curing refers to the process of liquid adhesive becoming solid. The curing process also includes a post-ripening process, that is, the reactive groups in the adhesive after preliminary curing further react or crystallize to obtain the final cured strength. For polyurethane adhesives, the curing process is a process in which the NCO groups in the glue react completely, or the solvent evaporates completely and the polyurethane molecular chains crystallize, so that the adhesive and the substrate have a sufficiently high bonding force. The specific manufacturing method is as follows: first, a polyurethane adhesive is coated on the side of the PET film facing the light guide layer 12, and the polyurethane adhesive is solidified to form a solid adhesive layer with high adhesion; then, an appropriate amount of water is sprayed on the solid adhesive layer, and the light guide layer 12 is placed on the solid adhesive layer. After the water molecules on the solid adhesive layer evaporate, the light guide layer 12 can be firmly bonded to the PET film. Since the polyurethane adhesive has been solidified at this time, it will not block the scattered light points; finally, the PET films on the inner and outer sides of the light guide layer 12 are bonded to the inner and outer cup bodies with liquid epoxy resin glue, thereby realizing the production of the cup body 1. Epoxy resin glue is not only low in toxicity, low in volatility, easy to operate, and has strong adhesion, but also has high light transmittance, and will not affect the light guiding effect of the light guide layer 12. The PET film plays a role in isolating the epoxy resin glue and the light guide layer 12, which can prevent the liquid epoxy resin glue from blocking the scattered light points.

3 and 4 , the light guide layer 12 includes a side enclosure 121, a bottom plate 122 and a connecting plate 123. The side enclosure 121 is vertically connected to the outer peripheral edge of the bottom plate 122 through the connecting plate 123. A main reflector 124 inclined at 45° is provided inside the connecting plate 123. The main reflector 124 reflects most of the vertical light emitted by the light emitting body 21 on the top surface of the side enclosure 121 into the bottom plate 122 to form horizontal light, thereby allowing the bottom of the outer cup body 13 to emit light evenly, thereby presenting a good visual effect of being transparent throughout.

Referring to Figures 1 and 2, based on the three-layer cup body structure of the luminescent ceramic cup, two important factors that affect the light guiding effect of the light guiding layer 12 are the light transmittance of the outer cup body 13 and the light intensity of the light source 21. From the top of the cup body 1 to the bottom of the cup body 1, as the emission distance of the light source 21 increases, the light intensity will gradually weaken, so the outer cup body 13 may have uneven light emission from top to bottom. In order to solve this problem, the present embodiment starts with the light transmittance of the outer cup body 13, and adjusts the wall thickness of the outer cup body 13 so that it gradually increases with the increase of the emission distance of the light source 21. As a result, the light transmittance of the outer cup body 13 gradually increases with the increase of the emission distance of the light source 21, so that the outer cup body 13 presents a uniform light emitting effect that is consistent from top to bottom.

Referring to Figures 3 and 5, in order to enrich the luminous effect of the cup body 1 and make the outer cup body 13 project an indicative pattern, the following two schemes can be adopted to supplement the design of the cup body 1: First, a protrusion or a recess 131 is set in the corresponding area of the inner side surface of the outer cup body 13 according to the set pattern, so that the light transmittance of the corresponding area of the outer cup body 13 changes significantly, thereby projecting the set pattern; second, a reflective film 111 is set in the corresponding area of the outer side surface of the inner cup body 11 according to the set pattern, so that the light intensity in the corresponding area is significantly enhanced, thereby projecting the set pattern. In practical applications, these two schemes can be used separately or simultaneously. In order to reduce the difficulty of production, the second scheme is preferred in this embodiment. It should be noted that the "indicative pattern" mentioned in this embodiment can be a personal signature, a brand logo or any pattern with a decorative effect. Therefore, the luminous ceramic cup has a wide design space and rich usage scenarios, which can meet people's diverse customization needs.

Referring to Figures 2 and 3, an annular groove 20 for installing the light-emitting body 21 is provided at the bottom of the cup cover 2, and the annular groove 20 is equipped with a detachable transparent cover 22. When the light-emitting body 21 needs to be replaced, it is only necessary to remove the transparent cover 22 to operate. The light-emitting body 21 is preferably an LED light strip, and the related accessories such as batteries or circuit boards required for its light emission are all arranged inside the cup cover 2.

Referring to Figures 2 and 3, in actual applications, the use scenarios or functions of the luminescent ceramic cup can be enriched by enriching the luminescent colors of the luminescent body 21. For example, a temperature sensing probe for detecting the temperature of the solution can be set at the bottom of the cup cover 2, and the luminescent color of the luminescent body 21 can be set in different temperature ranges, so that the luminescent ceramic cup has a temperature detection function and can emit light of different colors in different temperature ranges; buttons for different solution types can also be set on the top of the cup cover 2, so that the luminescent color of the luminescent body 21 changes according to the different solution types.

Referring to Figures 1 and 3, the inner cup body 11 is made of ceramic or stainless steel. In order to increase the structural strength of the luminous ceramic cup, this embodiment uses stainless steel to make the inner cup body 11.

Referring to Figures 3 to 5, as a preferred solution, the light guide layer is made of a special glass fiber light guide plate.

Example 2:

6 to 8 , this embodiment is different from the first embodiment in the following aspects:

(1) In order to improve the problem that the light intensity of the outer cup body 13 gradually weakens as the emission distance increases, the present embodiment is provided with a reflective film 111 on the outer side of the entire inner cup body 11, and the reflective degree of the reflective film 111 gradually increases as the emission distance of the light source 21 increases. By providing a reflective film 111 with a reflective degree gradually changing from weak to strong, a gradual reflection can be achieved, so that the light projected onto the outer cup body 13 is uniform. The reflective film 111 can be made by splicing together a plurality of reflective materials with different reflective degrees in sequence, or it can be made in one piece using an existing reflective film 111 preparation process, which is not limited here.

(2) In order to make the outer cup body 13 project an indicative pattern, the present embodiment sets a recess 131 in the corresponding area of the inner side surface of the outer cup body 13 according to the set pattern, so that the wall thickness of the corresponding area of the outer cup body 13 is significantly smaller than the wall thickness of other areas, thereby causing a significant change in the light transmittance, thereby projecting the set pattern.

(3) Embodiment 1: A main reflector 124 inclined at 45° is provided inside the connecting plate of the light-guiding layer 12 to make the bottom of the cup body 1 emit light. However, the area where the main reflector 124 is provided will have a dark area because the light is blocked. In order to solve this problem, this embodiment optimizes and improves the structure of the light-guiding layer 12 of the cup body 1 as follows: a mounting groove 125 is provided at the outer angle of the bottom of the connecting plate 123, and the mounting groove 125 has a first inclined surface, a second inclined surface and a third inclined surface. The connecting plate 123 surrounding the mounting groove 125 is correspondingly divided into a first side plate 1231, a second side plate 1232 and a third side plate 1233; the second inclined surface is provided with the main reflector 124; the first inclined surface has an angle a with the outer side surface of the first side plate 1231, and the first inclined surface is provided with a first secondary reflector 1 26, the first secondary reflector 126 reflects part of the vertical light emitted by the luminous body 21 to the bottom edge of the outer cup body 13; the second secondary reflector 127 inclined at 45° is provided at the inner corner of the second side plate 1232, the third inclined surface and the bottom surface of the third side plate 1233 form an angle b, and the third inclined surface is provided with a third secondary reflector 128, part of the vertical light emitted by the luminous body 21 is reflected by the second secondary reflector 127 into the second side plate 1232 to form horizontal light, and is reflected by the third secondary reflector 128 to the bottom edge of the outer cup body 13. It can be seen that by providing a plurality of secondary reflectors that cooperate with the main reflector 124, the light of the luminous body 21 can be refracted to different degrees at the bottom of the cup body 1, thereby solving the problem that there is a dark area at the bottom edge of the cup body 1 (especially at the bottom angle) due to the provision of the main reflector 124, and further improving the overall lighting effect of the cup body 1. In practical applications, the main reflector 124, the first secondary reflector 126, the second secondary reflector 127 and the third secondary reflector 128 can all be reflective films or reflective plates. As a preferred solution, the angles a and b are both in the range of 15°-30°, thereby ensuring that the light is refracted to the bottom edge of the cup body 1.

The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
