Description

Technical Field

[0001] This utility model belongs to the technical field of ceramic daily necessities and intelligent electronic accessories. Specifically, it relates to an intelligent ceramic cup that can be wirelessly powered and whose light changes with temperature. It is suitable for daily drinking, gift customization, home decoration, cultural and creative display and other scenarios. Background Technology

[0002] Ceramic mugs are widely used in daily life, business gifts, and cultural and creative gifts, characterized by their safe materials, high-temperature resistance, beautiful appearance, and strong cultural attributes. However, existing ceramic mugs on the market are relatively simple in function, usually only having the basic function of holding drinking water or beverages, lacking in intelligence, fun, and practicality.

[0003] Existing smart ceramic products mainly suffer from the following problems: First, some ceramic cups with lighting effects use a built-in lithium battery with wired charging, resulting in exposed charging ports. Long-term use makes them prone to water and dust accumulation, leading to short circuits or damage. Frequent plugging and unplugging of the charging cable is inconvenient, and lithium batteries also pose safety hazards such as bulging and aging. Second, in existing technologies, some ceramic cups with lighting displays place the display unit or light-transmitting window on the outer surface of the cup body, increasing structural complexity and affecting the cup's sealing and waterproofing performance. Temperature-changing ceramic cups using a thermal coating for physical color change suffer from low color-changing accuracy, large temperature difference ranges, and difficulty in accurately reflecting water temperature. Furthermore, the coating is prone to peeling and fading under long-term high-temperature erosion, resulting in poor durability. Third, traditional smart ceramic cups have relatively fixed lighting modes and cannot dynamically adjust the color and brightness according to water temperature, resulting in insufficient interactivity and visual appeal. Fourth, the split power supply structure has poor sealing, and the rough connection between the cup body and electronic components makes it easy for dust and water to enter, making it difficult to clean and failing to meet daily-use ceramic hygiene standards.

[0004] Therefore, existing ceramic cups suffer from problems such as easy damage due to wired charging and potential battery safety hazards, inaccurate temperature display, limited lighting effects and poor interactivity, complex structure due to the need to place the display unit or light-transmitting window on the outer surface of the cup, which is not conducive to sealing and waterproofing, and poor durability of the heat-sensitive coating. It is necessary to develop a smart ceramic cup with wireless power supply, precise temperature control, dynamic lighting display, simplified structure, and integrated sealing. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned defects in the existing technology and provide a smart ceramic cup that can be wirelessly powered and switches lights according to temperature changes. This solves the technical problems of traditional ceramic cups, such as easy damage from wired charging, safety hazards of batteries, inaccurate temperature display, monotonous lighting effects, complex structure due to the display unit or light-transmitting window being set on the outer surface of the cup body, which is not conducive to sealing and waterproofing, and poor durability of heat-sensitive coating. The new model achieves wireless and seamless power supply, accurate water temperature monitoring, temperature-linked light switching, overall sealing and waterproofing, simplified structure, and integrated design.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smart ceramic cup that can be wirelessly powered and whose light changes with temperature includes a ceramic cup. The bottom wall of the ceramic cup is provided with a delicate eye carved by a fine carving technique. Below the bottom wall of the cup, there is a sealed mounting cavity (7) formed by a ceramic sealing sheet (8) and the bottom foot of the ceramic cup through a seamless sealing process, so that a completely sealed waterproof cavity is formed between the bottom wall of the cup and the ceramic sealing sheet. The sealed mounting cavity is provided with a main control circuit board, a wireless power supply module and a temperature detection module. The main control circuit board integrates the main control module and is provided with a driving circuit for the light display module.

[0008] The main control module includes a main control chip disposed on the main control circuit board; a wireless receiving coil is soldered and fixed to the bottom of the main control circuit board;

[0009] The wireless power supply module includes the wireless receiving coil and the Qi standard wireless charging receiving chip. The Qi standard wireless charging receiving chip is electrically connected to the wireless receiving coil and is used to supply power to the main control module, the temperature detection module and the light display module.

[0010] The temperature detection module includes a high-precision patch temperature sensor and a sampling conditioning circuit. The high-precision patch temperature sensor is closely attached to the bottom wall of the cup body and is electrically connected to the main control chip through the sampling conditioning circuit.

[0011] The "delicate eye" is located at the center of the bottom wall of the cup body, and the number of the "delicate eye" is at least one; when there are multiple "delicate eyes", the multiple "delicate eyes" are evenly distributed in a ring around the center of the bottom wall of the cup body, and the number of them evenly distributed around the center is 5 to 12.

[0012] The lighting display module includes full-color LED beads and the driving circuit. The full-color LED beads are mounted on the top of the main control circuit board and face the Linglong Eye. The full-color LED beads are electrically connected to the main control chip through the driving circuit.

[0013] The main control chip has a preset temperature threshold and controls the light display module to switch the light display state according to the temperature detected by the temperature detection module.

[0014] The intricate eye design ensures that the light emitted through the eye is evenly distributed in all directions within the cup and the water, creating a uniform and soft overall lighting effect. The ceramic sealing sheet can be an ultra-thin zirconia ceramic disc, which is impact-resistant and thermally conductive. The entire smart ceramic cup achieves an IP67 waterproof rating, allowing for direct washing or immersion.

[0015] Preferably, the wireless power supply module further includes a voltage regulator circuit and an energy storage capacitor. The Qi standard wireless charging receiver chip integrates a rectification and voltage regulation circuit and a protocol communication circuit. The wireless power supply module uses pure wireless electromagnetic induction for power, without a built-in lithium battery or charging interface, relying on the energy storage capacitor and voltage regulator circuit for continuous power supply.

[0016] Preferably, the high-precision patch temperature sensor is an NTC temperature sensor. The sampling and conditioning circuit is located on the main control circuit board and is used to sample and condition the signal output by the temperature sensor before sending it to the main control chip.

[0017] Preferably, the main control chip has three preset temperature thresholds: a low-temperature mode (0℃ to 30℃) controls the full-color LED beads to display blue cool light; a normal-temperature mode (greater than 30℃ and less than or equal to 40℃) controls the full-color LED beads to display green warm light; and a high-temperature mode (greater than 40℃) controls the full-color LED beads to display red warning light. Furthermore, at temperatures above 60℃, the red warning light is controlled to flash at a frequency of approximately 1Hz. Simultaneously, the main control chip can also fine-tune the light brightness according to temperature changes, with higher temperatures resulting in higher light brightness.

[0018] Preferably, the ceramic cup employs an ultra-thin, translucent ceramic glaze process, with thin-walled sidewalls. Light, diffused through the light source, shines evenly through the sidewalls and the water inside, avoiding localized light spots and glare. Furthermore, the sidewalls of the ceramic cup feature engraved textures, which are highlighted when light shines through, achieving a creative lighting display effect.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Wireless power supply, convenient and safe to use. This utility model abandons the traditional wired charging and built-in lithium battery structure, and adopts electromagnetic induction wireless power supply technology. It is compatible with universal wireless charging devices, realizing contactless charging and use anytime, anywhere. There is no charging interface, no battery bulging or aging risks, and it can effectively solve problems such as water damage and circuit failure, thus improving the service life of the device.

[0021] 2. Precise temperature control and strong visualization effect. It adopts a high-precision electronic temperature sensor to replace the traditional thermochromic coating, which ensures accurate and stable temperature detection and eliminates the problems of coating peeling and fading. Different colored lights are used to intuitively indicate the water temperature range, reducing the risk of scalding from hot drinking water.

[0022] 3. Intelligent lighting linkage adds a lot of fun. The lights dynamically switch between blue, green, and red according to the water temperature, and the brightness is adjusted accordingly. The light is diffused by the ceramic's soft light, resulting in a better texture. This breaks away from the limitations of the traditional ceramic cup's monotonous appearance, combining decorative and interactive features, making it suitable for cultural and creative gifts and home décor.

[0023] 4. Fully sealed integrated design for high durability. By employing a delicate carving technique to create a "delicate eye" on the bottom wall of the ceramic cup, and mounting full-color LED beads on the top of the main control circuit board directly opposite this eye, the light is allowed to pass through the light-transmitting but waterproof properties of the eye, achieving a unified lighting display and waterproof seal. The ceramic sealing sheet and the cup base are seamlessly sealed using a sealant process, forming a completely sealed waterproof cavity between the bottom wall and the ceramic sealing sheet. The overall design achieves IP67 waterproof rating, allowing for complete washing. It is not easily damaged by everyday bumps and knocks. The ceramic body has no external openings, preserving the material advantages and aesthetic appeal of traditional ceramic cups.

[0024] 5. Simple structure, controllable cost, and easy to mass-produce. There is no need to add extra light-transmitting windows or light guides to the outer surface of the cup. Instead, the intricate holes on the bottom wall of the cup serve as the light transmission channel. The overall structure is streamlined, suitable for mass firing and automated assembly of ceramics, and can be widely used in daily-use ceramics, high-end cultural and creative gifts, and customized ceramic products.

[0025] 6. Intuitive temperature visualization and a superior user experience. Because the LED sensor is located on the bottom wall of the cup, and full-color LED beads are mounted on the top of the main control circuit board directly facing it, the light is diffused through the sensor and then evenly emitted through the cup and the water inside, giving the cup and the water a color that corresponds to the temperature. Users do not need to specifically observe any particular window; they can intuitively perceive the water temperature range simply by observing the color of the light on the cup itself or the water, achieving a direct and intuitive "temperature-sensing" experience.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The following embodiments are only used to illustrate the technical solution of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0030] Example 1

[0031] See Figure 1 and Figure 2 This embodiment provides a smart ceramic cup that can be wirelessly powered and whose light changes with temperature. The main body is a round ceramic cup body 1 fired at high temperature kaolin clay, with a smooth and rounded surface and a translucent white glaze. The bottom wall of the cup body has a delicate eye 2 formed using a delicate carving technique; the eye is translucent but not water-permeable. The delicate eye is located at the center of the bottom wall of the cup body, and the number of delicate eyes is at least one; when there are multiple delicate eyes, they are evenly distributed in a ring around the center of the bottom wall of the cup body, with a number ranging from 5 to 12. In this embodiment, the delicate eyes are located at the center of the bottom wall of the cup body, and the number is 5. A sealed mounting cavity 7 is provided below the bottom wall of the cup body, and the smart ceramic cup has no exposed openings.

[0032] The ceramic sealing sheet 8 is made of an ultra-thin zirconia ceramic disc, which is impact-resistant and thermally conductive. It is seamlessly bonded to the bottom of the ceramic cup using a high-temperature resistant and waterproof sealant, thus forming a completely sealed cavity between the bottom wall of the cup and the ceramic sealing sheet, i.e., the sealed installation cavity. This sealed installation cavity houses a main control module, a wireless power supply module, a temperature detection module, and a light display module. Specifically, it includes: a main control circuit board 3, with a wireless receiving coil 4 soldered to the bottom of the main control circuit board. The wireless receiving coils are arranged in a ring, facing the external wireless charging transmitter, and support 5V universal wireless power supply; the main control circuit board integrates the main control module, which includes a main control chip; the main control circuit board also houses the drive circuit for the light display module.

[0033] A high-precision patch temperature sensor 5 is mounted on the side of the main control circuit board. This high-precision patch temperature sensor is tightly attached to the bottom wall of the cup and is used to collect water temperature data inside the cup. The temperature detection module also includes a sampling and conditioning circuit, which is located on the main control circuit board. The high-precision patch temperature sensor is electrically connected to the main control chip through the sampling and conditioning circuit.

[0034] A full-color LED bead (6) is mounted on the top of the main control circuit board, positioned directly opposite the light display window on the bottom wall of the cup. The full-color LED bead is electrically connected to the main control chip via a driver circuit. After being diffused through the light display window, the light shines evenly through the cup and the water inside, creating a soft, diffused light effect. Users do not need to specifically observe any particular light-transmitting window; they can intuitively perceive the water temperature range simply by observing the color of the light on the cup itself or the water within.

[0035] The wireless power supply module includes a wireless receiving coil and a Qi standard wireless charging receiver chip. The Qi standard wireless charging receiver chip is electrically connected to the wireless receiving coil and is used to power the main control module, temperature detection module, and light display module. The wireless power supply module also includes a voltage regulator circuit and an energy storage capacitor. The Qi standard wireless charging receiver chip integrates a rectification and voltage regulation circuit and a protocol communication circuit, and can also integrate one or more of overvoltage protection, overcurrent protection, and overheat protection.

[0036] See Figure 2 The specific circuit implementation of each module is as follows: The wireless receiving coil receives electrical energy emitted by the external wireless charging base through electromagnetic induction. The Qi standard wireless charging receiving chip is electrically connected to the wireless receiving coil, rectifies and regulates the received AC power, and outputs DC power, which is then supplied to the main control module, temperature detection module, and light display module via a voltage regulator circuit and energy storage capacitor. In the temperature detection module, the NTC temperature sensor is closely attached to the bottom wall of the cup, and its resistance changes with temperature. The sampling and conditioning circuit is located on the main control circuit board and is used to sample and condition the voltage signal output by the NTC temperature sensor before sending it to the main control chip. In the main control module, the main control chip has a preset temperature threshold. After receiving the temperature signal from the sampling and conditioning circuit, it judges and decodes the signal through threshold comparison and color decoding circuit, and outputs the corresponding control signal to the drive circuit of the light display module. In the light display module, the drive circuit receives the control signal output by the main control chip and drives the full-color LED beads to emit light. The full-color LED beads adopt an RGB segmented plus constant white light mode, and can switch between blue, green, and red light according to the control signal.

[0037] Preferably, this embodiment also includes a 60°C determination and red LED flashing control circuit. This circuit includes a comparator U3 (preferably TLV3201), a timer U4 (preferably LTC6991), and a switching transistor Q4. When the temperature signal reaches the 60°C determination threshold, comparator U3 outputs a trigger signal to timer U4. Timer U4 outputs a pulse signal of approximately 1Hz to control the switching transistor Q4, causing the red LED to flash at approximately 1Hz. The threshold comparison and color decoding circuit can use comparator U1 (preferably TLV1704), whose output is an open-collector output.

[0038] During operation, the ceramic cup is placed on a universal wireless charging base. The wireless receiving coil obtains power through electromagnetic induction, which is then regulated by a voltage regulator circuit to power the main control module, temperature detection module, and light display module. The temperature sensor collects the water temperature inside the cup in real time and transmits the temperature signal to the main control chip via a sampling and conditioning circuit. The main control chip has preset temperature thresholds. When the water temperature is in the cold water range of 0℃ to 30℃, the main control chip controls the full-color LED beads to emit a soft blue light; when the water temperature is above 30℃ but below or equal to 40℃ (suitable for drinking), the main control chip controls the full-color LED beads to emit a warm green light; when the water temperature is above 40℃ (high temperature range), the main control chip controls the full-color LED beads to emit a bright red light, serving as a high-temperature warning. Furthermore, when the water temperature is above 60℃, the main control chip can control the red light to flash at a frequency of approximately 1Hz to enhance the warning effect. The main control chip can also fine-tune the light brightness according to temperature changes, with higher temperatures resulting in brighter lights.

[0039] In this embodiment, the smart ceramic cup has no exposed circuit structure, can be directly washed with water, is waterproof and drop-proof, and will not fade or malfunction after long-term use. The light shines through the ceramic cup to create a uniform and soft light effect.

[0040] Example 2

[0041] This embodiment is basically the same as Embodiment 1 in structure and working principle, the difference being that: the ceramic cup body adopts a colored engraving ceramic process, with cultural and creative patterns such as landscapes, buildings, figures, and flowers engraved on the cup body. When light shines through, the engraved texture can be highlighted, combining light with the ceramic engraving process to enhance the cultural and creative value of the product, making it suitable for high-end customized gifts and craft ceramic products.

[0042] In addition, the main control module in this embodiment also features a new breathing and flashing light mode. Under high temperatures, the red light flashes slowly, and the flashing speed increases with higher temperatures, thereby further enhancing the warning effect, preventing accidental scalding, and improving product safety.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, any modifications, substitutions, and improvements made without departing from the principles of this utility model should fall within the protection scope of this utility model.
