Implementation Method

[0029] The specific embodiments of the present invention are 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.

[0030] Example 1:

[0031] 1 to 3 , this embodiment provides a luminous ceramic cup, comprising a cup body 1 and a cup lid 2. The cup body 1 comprises an inner cup body 11, a light-guiding layer 12, and an outer cup body 13 nested in sequence. The outer cup body 13 is made of translucent ceramic. The light-guiding layer 12 is provided with a plurality of scattered light points. The top surface where the light-guiding layer 12 and the cup lid 2 abut against each other is the light-entering surface, and the outer side surface where the light-guiding layer 12 and the outer cup body 13 abut against each other is the light-emitting surface. A luminous body 21 is provided around the light-guiding layer 12 at the bottom of the cup lid 2. The light emitted by the luminous body 21 enters the interior of the light-guiding layer 12 from the light-entering surface, is scattered by the scattered light points, and is emitted from the light-emitting surface, thereby evenly projected onto the outer cup body 13, thereby converting a point-like or strip-like light source into a surface light source, thereby enhancing the luminous effect of the ceramic cup. In this embodiment, the luminous body 21 is arranged at the bottom of the cup lid 2, and the light-guiding layer 12 is arranged inside the cup body 1, thereby realizing a split design of the light-emitting device, which is convenient for cleaning or replacing components, and has higher practicality and convenience.

[0032] Referring to Figures 3 and 5 , the light guide layer 12 is laser-engraved with several scattered light spots. If ordinary glue is used to directly bond the light guide layer 12 to the inner and outer cups 11 and 13, the liquid glue will enter the scattered light spots, blocking them and preventing light from escaping. This ultimately affects the light scattering effect, resulting in poor luminescence from the outer cup 13 and the appearance of abnormal localized dark areas. To address this issue, the present embodiment provides a protective film 14 between the light guide layer 12 and both the inner and outer cups 11 and 13. The protective film 14 is bonded to the light guide layer 12 via a first adhesive 141 and to either the inner or outer cup 11 and 13 via a second adhesive 142. The first adhesive 141 and the protective film 14 together form 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.

[0033] 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. Polyurethane adhesive does not immediately have a high bonding strength during bonding and needs to be cured. The so-called curing refers to the process of liquid adhesive becoming solid. The curing process also includes a post-curing 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 production method is as follows: first, a polyurethane adhesive is applied to the side of the PET film facing the light guide layer 12, and the 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, liquid epoxy resin glue is used to bond the PET films on the inner and outer sides of the light guide layer 12 to the inner and outer cup bodies, 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 serves to isolate the epoxy resin glue and the light guide layer 12, thereby preventing the liquid epoxy resin glue from clogging the scattered light points.

[0034] 3 and 4 , the light guide layer 12 includes a side panel 121, a bottom plate 122 and a connecting plate 123. The side panel 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 panel 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.

[0035] 1 and 2 , based on the three-layer cup 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 luminous body 21. From the top of the cup body 1 to the bottom of the cup body 1, as the emission distance of the luminous body 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, this embodiment starts with the light transmittance of the outer cup body 13, and by adjusting the wall thickness of the outer cup body 13, it gradually increases with the increase of the emission distance of the luminous body 21, thereby making the light transmittance of the outer cup body 13 gradually increase with the increase of the emission distance of the luminous body 21, so that the outer cup body 13 presents a uniform light-emitting effect that is consistent from top to bottom.

[0036] 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, according to the set pattern, a protrusion or recess 131 is set in the corresponding area of ​​the inner side surface of the outer cup body 13, so that the light transmittance of the corresponding area of ​​the outer cup body 13 changes significantly, thereby projecting the set pattern; second, according to the set pattern, a reflective film 111 is set in the corresponding area of ​​the outer side surface of the inner cup body 11, so that the light intensity of the corresponding area is significantly enhanced, thereby projecting the set pattern. In actual applications, these two schemes can be used alone or at the same time. 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.

[0037] Referring to Figures 2 and 3, the bottom of the cup lid 2 is provided with an annular groove 20 for mounting a light source 21. This groove 20 is equipped with a removable transparent cover 22. When the light source 21 needs to be replaced, the transparent cover 22 can be removed. The light source 21 is preferably an LED light strip, and the necessary components, such as the battery and circuit board, are housed within the cup lid 2.

[0038] 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 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 in different temperature ranges can be set, so that the luminescent ceramic cup has the function of temperature detection 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 type of solution.

[0039] 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, the inner cup body 11 is made of stainless steel in this embodiment.

[0040] 3 to 5 , as a preferred embodiment, the light guide layer is made of a special glass fiber light guide plate.

[0041] Example 2:

[0042] 6 to 8 , this embodiment differs from the first embodiment in the following aspects:

[0043] (1) In order to improve the problem of the outer cup body 13 gradually weakening due to the increase of the emission distance, 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 with the increase of the emission distance of the light source 21. By providing the 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 the existing reflective film 111 preparation process, which is not limited here.

[0044] (2) In order to make the outer cup body 13 project a distinctive pattern, this embodiment provides 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 that of other areas, thereby significantly changing the light transmittance and projecting the set pattern.

[0045] (3) In the first embodiment, a main reflector 124 inclined at 45 degrees is provided inside the connecting plate of the light-guiding layer 12, so that the bottom of the cup body 1 emits 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 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 light emitting element 21 toward the bottom edge of the outer cup 13. A second secondary reflector 127 is provided at the inner corner of the second side panel 1232, inclined at 45°. The third inclined surface forms an angle b with the bottom surface of the third side panel 1233, and a third secondary reflector 128 is provided on the third inclined surface. Part of the vertical light emitted by the light emitting element 21 is reflected by the second secondary reflector 127 into the second side panel 1232, forming horizontal light. The light is then reflected by the third secondary reflector 128 toward the bottom edge of the outer cup 13. Thus, by providing multiple secondary reflectors that cooperate with the primary reflector 124, light from the light emitting element 21 can be refracted to varying degrees at the bottom of the cup 1. This solves the problem of dark areas at the bottom edge of the cup 1 (particularly at the bottom angle) caused by the primary reflector 124, further improving the overall lighting effect of the cup 1. In practical applications, the primary 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. Preferably, the angles a and b are both within a range of 15°-30°, ensuring that the light is refracted to the bottom edge of the cup body 1.

[0046] The above is only a specific implementation 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.
