Description

Technical Field

[0001] This utility model relates to the field of luminous cup manufacturing technology, specifically to a luminous cup. Background Technology

[0002] Induction-activated illuminated cups work by placing a sensor and a light-emitting element at the bottom of the cup. The sensor detects the liquid level inside the cup to create a corresponding light effect. For example, when the cup is empty, the light-emitting element does not emit light; when liquid is present, the element emits light. Alternatively, the light-emitting effect may vary depending on the depth of the liquid inside the cup.

[0003] However, because electrical components need to be installed inside the bottom of the cup, the bottom of existing luminous cups is often designed to be frosted and semi-transparent in order to conceal these components. Therefore, on the one hand, this affects the overall transparency of the cup, detracting from its aesthetics; on the other hand, the light effect is obscured, resulting in insufficient brightness of the light. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a luminous cup that enhances the overall transparency and aesthetics when not emitting light, and improves the illumination effect of light on the cup body and the liquid inside the cavity when emitting light.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A luminous cup, comprising:

[0007] The cup body has a transparent base and a cavity defined inside the cup body. The cup body includes a cup wall that defines the sides of the cavity and a cup bottom that defines the bottom of the cavity.

[0008] A light-emitting encapsulation module is placed at the bottom of the cup. The light-emitting encapsulation module is transparent in the center of the bottom of the cup to form a light-transmitting area. The light-emitting encapsulation module includes an electrical component and an encapsulation body encapsulated outside the electrical component and connected to the bottom of the cup. The encapsulation body is transparent at least in the light-transmitting area. The electrical component includes several electrical devices electrically connected through a control circuit. The electrical devices include:

[0009] The capacitive sensing sheet is located at least partially within the light-transmitting area, and is transparent at least within the light-transmitting area. The capacitive sensing sheet is used at least to sense the liquid state within the cavity. The capacitive sensing sheet is electrically connected to the control circuit outside the light-transmitting area to prevent solder joints from affecting the light transmittance of the light-transmitting area.

[0010] The control chip, battery, and light-emitting element are located on the periphery of the light-transmitting area.

[0011] This application discloses a luminous cup, the principle of which is as follows: a capacitive sensing element detects the liquid state within the cavity and sends a signal to a control chip. The control chip then controls the luminous state of the light-emitting element according to preset control logic. A battery powers the electrical components. Due to the design of the light-transmitting area, when the light-emitting element is not emitting light, the bottom of the cup corresponding to the light-transmitting area is transparent, maximizing its resemblance to ordinary transparent cups and improving the overall aesthetic appeal compared to existing luminous cups that obscure the bottom. When the light-emitting element emits light, the emitted light penetrates unobstructed through the center of the bottom of the cup, enhancing the illumination effect on the cup body and the liquid within the cavity. Furthermore, the capacitive sensing element and electrical components are encapsulated within a package, ensuring waterproof sealing.

[0012] Furthermore, in this application, a luminous cup also includes a charging coil, which surrounds the light-transmitting area. As a preferred embodiment, the charging coil charges the battery, and is encapsulated within a package. The charging coil also features a ring-shaped distribution, effectively saving space to maximize the light-transmitting area.

[0013] Furthermore, one luminous cup in this application also includes a shielding sheet located below the capacitive sensing sheet. As a preferred embodiment of this application, the shielding sheet is provided to prevent accidental contact with the bottom of the cup from causing the luminous element to emit light unnecessarily.

[0014] Furthermore, in a light-emitting cup of this application, the capacitive sensing sheet includes a positive sensing sheet and a negative sensing sheet surrounding the outer periphery of the positive sensing sheet. The positive sensing sheet is disposed in the light-transmitting area, and the positive sensing sheet has a pin extending outward from the light-transmitting area. One end of the pin extending outward from the light-transmitting area is electrically connected to the control circuit.

[0015] Furthermore, in one of the light-emitting cups in this application, both the negative electrode sensor and the positive electrode sensor are located within the light-transmitting area, and both the negative electrode sensor and the positive electrode sensor are provided with pins that extend beyond the light-transmitting area and are electrically connected to the control circuit.

[0016] Furthermore, in one luminous cup of this application, the negative electrode sensing sheet has an opening, through which leads extending from the positive electrode sensing sheet pass. As a preferred embodiment of this application, the negative electrode sensing sheet is C-shaped. If the negative electrode sensing sheet is annular, the leads extending from the positive electrode sensing sheet would overlap longitudinally with the negative electrode sensing sheet, affecting the detection accuracy of the capacitive sensing sheet. With the above structure, the longitudinal overlap between the leads on the positive electrode sensing sheet and the negative electrode sensing sheet can be avoided, thereby improving detection accuracy.

[0017] Furthermore, in one of the luminous cups in this application, the pins and the capacitive sensing sheet are integrally formed, and the whole is transparent.

[0018] Furthermore, in one of the luminous cups of this application, the electrical components include a PCB board, and the control circuit is disposed on the PCB board. At least the light-transmitting area of ​​the PCB board is transparent.

[0019] Furthermore, in one type of luminous cup in this application, the luminous element is ring-shaped and arranged around the periphery of the light-transmitting area.

[0020] Preferably, in one of the luminescent cups of this application, the luminescent encapsulation module is filled at the bottom of the cavity, and the encapsulation body is a cured colloid.

[0021] Preferably, in one of the luminous cups of this application, a mounting groove is provided at the bottom of the cup, and a luminous encapsulation module is filled in the mounting groove.

[0022] Furthermore, in one luminescent cup of this application, the mounting groove extends radially outward beyond the inner diameter of the bottom of the cup wall to form an annular shielding area. Electrical components located outside the light-transmitting area are disposed within the annular shielding area, and the light-transmitting area covers the bottom of the cavity. As a preferred embodiment of this application, based on the above structure, the light-transmitting area can cover the bottom of the cavity, maximizing the light-transmitting area and ensuring the transparency and light transmission effect of the cup.

[0023] Furthermore, in one of the luminous cups in this application, the thickness of the cup wall gradually increases from top to bottom. This is a preferred embodiment of the application to avoid the cup wall becoming too thick at the top due to the presence of a ring-shaped shielding area, which would negatively impact the user experience.

[0024] Furthermore, one type of luminous cup in this application also includes decorative patterns or ornaments placed on the cup body and / or the luminous encapsulation module. It should be noted that even if the decorative patterns or ornaments are placed within the luminous encapsulation module, they are not components of the luminous encapsulation module described in this application.

[0025] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0026] This invention provides a luminous cup, the principle of which is as follows: a capacitive sensing element detects the liquid state within the cavity and sends a signal to a control chip. The control chip then controls the luminous state of the light-emitting element according to preset control logic. A battery powers the electrical components. Due to the design of the light-transmitting area, when the light-emitting element is not emitting light, the bottom of the cup corresponding to the light-transmitting area is transparent, maximizing its resemblance to ordinary transparent cups and improving the overall aesthetic appeal compared to existing luminous cups that obscure the bottom. When the light-emitting element emits light, the emitted light penetrates unobstructed through the center of the bottom of the cup, enhancing the illumination effect on the cup body and the liquid within the cavity. Furthermore, the capacitive sensing element and electrical components are encapsulated within a package, ensuring waterproof sealing. Attached Figure Description

Detailed Implementation

[0034] Combination Figures 1 to 2 The illuminated cup shown includes:

[0035] The cup body 1 has a transparent base and a cavity 10 defined inside the cup body 1. The cup body 1 includes a cup wall 11 that defines the sides of the cavity 10 and a cup bottom 12 that defines the bottom of the cavity 10.

[0036] A light-emitting encapsulation module 2 is placed at the bottom of the cup 12. The light-emitting encapsulation module 2 is transparent at the center of the bottom of the cup 12 to form a light-transmitting area 20. The light-emitting encapsulation module 2 includes an electrical component and an encapsulation body 22 encapsulated outside the electrical component and connected to the bottom of the cup 12. The encapsulation body 22 is transparent at least within the light-transmitting area 20. The electrical component includes several electrical devices electrically connected through a control circuit. The electrical devices include:

[0037] The capacitive sensing sheet is located at least partially within the light-transmitting area 20. The capacitive sensing sheet within the light-transmitting area 20 is transparent. The capacitive sensing sheet is used at least to sense the liquid state within the cavity 10. The capacitive sensing sheet is electrically connected to the control circuit outside the light-transmitting area.

[0038] The control chip, battery 23, and light-emitting element 24 are located around the light-transmitting area 20.

[0039] The principle of this luminous cup is as follows: a capacitive sensing element detects the liquid state within the cavity 10 and sends a signal to a control chip. The control chip controls the luminous state of the luminous element 24 according to preset control logic. A battery 23 powers the electrical components. Due to the light-transmitting area 20, when the luminous element 24 is not luminous, the bottom 12 of the cup corresponding to the light-transmitting area 20 is transparent, maximizing its resemblance to ordinary transparent cups and improving the overall aesthetics compared to existing luminous cups that obscure the bottom. When the luminous element 24 is luminous, the light emitted by the luminous element 24 can penetrate the center of the bottom 12 of the cup without obstruction, thus enhancing the illumination effect on the cup body 1 and the liquid within the cavity 10. Furthermore, the capacitive sensing element and the electrical components are encapsulated within a package 22, ensuring waterproof sealing. Specifically, the light-transmitting area 20 is generally circular, but in other embodiments, it can also be designed as a polygon.

[0040] Combination Figure 2 As shown, further, in this embodiment, the electrical device also includes a charging coil 25, which surrounds the light-transmitting area 20. The charging coil 25 is used to charge the battery 23. The charging coil 25 is encapsulated within the package 22 to achieve the charging function while ensuring sealing. The charging coil 25 also has a ring-shaped structural distribution, which effectively saves space to maximize the area of ​​the light-transmitting area 20.

[0041] In one embodiment, the control circuit is as follows Figure 4 As shown, the charging coil 25 is connected to the P1 interface, the battery 23 is connected to the P2 interface, the positive electrode induction plate 211 and the negative electrode induction plate 212 are connected to pins 1 and 2 of the P3 interface respectively, and the light-emitting element 24 is connected to the P4 interface. Figure 4 In the chip: XKT-R2 is a wireless charging receiver chip, BRCL3130MC is a single-cell lithium-ion / lithium polymer rechargeable battery pack protection chip, TC301F is a capacitive sensing chip, and BCR401UW6 is an LED constant current driver chip.

[0042] Combination Figure 2 As shown, in this embodiment, a shielding sheet 27 is further included, located below the capacitive sensing sheet. The shielding electrode sheet 27 is provided to prevent accidental contact of the bottom of the cup body 1 from causing the light-emitting element 24 to emit light unnecessarily. Specifically, the shielding electrode sheet 27 is transparent and placed inside the package 22. The materials of the capacitive sensing sheet and the shielding electrode sheet 27 are ITO. In other embodiments, the shielding sheet 27 may be opaque.

[0043] Combination Figure 2As shown, further in this embodiment, the capacitive sensing element includes a positive sensing element 211 and a negative sensing element 212 surrounding the outer periphery of the positive sensing element 211. The positive sensing element 211 is disposed within the light-transmitting area 20, and has a pin 210 extending outward from the light-transmitting area 20. One end of the pin 210 extending outward from the light-transmitting area 20 is electrically connected to the control circuit. Specifically, the positive sensing element 211 is circular. During use, the potential distribution corresponding to the capacitive sensing element is as follows... Figure 4 and Figure 5 As shown. The capacitance C1 when there is no water in the cavity 10 is 1.1305 × 10⁻¹¹ pF, and the capacitance C2 when there is no water in the cavity 10 is 1.9355 × 10⁻¹¹ pF. C2 > C1, therefore, the presence or absence of water in the cup can be sensitively detected. In one embodiment, the specific control logic monitors the presence of water and the light-emitting element 24 emits light, while it does not emit light when there is no water. In other embodiments, changes in the amount of water in the cavity 10 can be monitored to control changes in the brightness or color of the light-emitting element 24.

[0044] Furthermore, in this embodiment, both the negative electrode sensing sheet 212 and the positive electrode sensing sheet 211 are located within the light-transmitting area 20, and both the negative electrode sensing sheet 212 and the positive electrode sensing sheet 211 are provided with pins 210 that extend out of the light-transmitting area 20 and are electrically connected to the control circuit.

[0045] Combination Figure 2 As shown, further in this embodiment, the negative electrode sensing sheet 212 has an opening 2120, through which the pin 210 extending from the positive electrode sensing sheet 211 passes. That is, the negative electrode sensing sheet 212 is C-shaped. If the negative electrode sensing sheet 212 were annular, the pin 210 extending from the positive electrode sensing sheet 211 would overlap longitudinally with the negative electrode sensing sheet 212, affecting the detection accuracy of the capacitive sensing sheet. With the above structure, the longitudinal overlap between the pin 210 on the positive electrode sensing sheet 211 and the negative electrode sensing sheet 212 can be avoided, thereby improving detection accuracy. Specifically, the pin 210 is integrally formed with the capacitive sensing sheet and is transparent overall.

[0046] Combination Figure 2 As shown, further, in this embodiment, the electrical component includes a PCB board 26, and the control circuit is disposed on the PCB board 26. The PCB board 26 is transparent and / or perforated at least in the light-transmitting area 20. Specifically, the PCB board 26 is made entirely of a transparent flexible circuit board material, such as polyethylene terephthalate transparent circuit board substrate.

[0047] Furthermore, in this embodiment, the light-emitting element 24 is ring-shaped and is arranged around the periphery of the light-transmitting area 20.

[0048] Combination Figure 1 and Figure 2As shown, in this embodiment, the bottom of the cup 12 is provided with a mounting groove 120, and the light-emitting encapsulation module 2 is filled in the mounting groove 120.

[0049] Furthermore, in this embodiment, the mounting groove 120 extends radially outward beyond the inner diameter of the bottom of the cup wall 11 to form an annular shielding region 1201. Electrical components located outside the light-transmitting region 20 are disposed within the annular shielding region 1201, and the light-transmitting region 20 covers the bottom of the cavity 10. Based on the above structure, the light-transmitting region 20 can cover the bottom of the cavity 10, maximizing the light-transmitting region 20 and ensuring the transparency and light transmission effect of the cup. In this embodiment, the encapsulation body 22 is a cured colloid.

[0050] Furthermore, in this embodiment, the thickness of the cup wall 11 gradually increases from top to bottom. This is to avoid the cup wall 11 becoming too thick at the top due to the setting of the annular shielding area 1201, which would affect the user experience.

[0051] Combination Figure 3 As shown, in another embodiment, the light-emitting encapsulation module 2 is filled at the bottom of the cavity 10, and the encapsulation body 22 is a cured colloid. Specifically, the encapsulation body 22 is a food-grade transparent photosensitive resin material. Furthermore, in this embodiment, a shielding layer (not shown) can be provided inside the encapsulation body 22 to shield electrical components located outside the light-transmitting area 20. To improve the aesthetics after setting the shielding layer, the shape of the shielding layer can be set as an annular shape, and the color of the shielding layer can be a reflective coating such as a metallic color or a mirror finish.

[0052] In other embodiments, decorative patterns or ornaments (not shown) are also included on the cup body and / or the light-emitting encapsulation module.
