Description

Technical Field

[0001] This utility model relates to an energy-saving intelligent drinking water management coaster with automatic recording function, belonging to the field of mechanical technology, specifically the field of intelligent healthy drinking water management equipment technology. Background Technology

[0002] As users' awareness of health management continues to increase, drinking assistance devices based on weight detection principles are gradually being applied in office and home settings, with some products implementing basic drinking behavior reminder functions. However, through investigation and technology comparison, it has been found that existing technologies still have the following prominent problems in terms of structural integration, power consumption control capabilities, and adaptability:

[0003] 1. Low structural integration: Existing drinking water management equipment generally adopts a separate modular layout, with weight sensing, power management, communication and reminder structures being independent of each other, which makes packaging difficult and susceptible to environmental interference;

[0004] 2. Weak energy consumption control structure: Most devices lack an event-driven wake-up mechanism, resulting in short battery life in resident mode and difficulty in long-term independent operation;

[0005] 3. Redundancy in communication module configuration: Traditional Bluetooth communication structures require long-term pairing and connection, resulting in high power consumption and poor compatibility with different terminals;

[0006] 4. Limited reminder structure: Most only provide LED reminder functions, without forming a multi-channel reminder mechanism, resulting in limited reminder effect and weak adaptability to different scenarios;

[0007] 5. Insufficient structural versatility and external compatibility: Some products are designed for specific sizes of water cups or custom containers, making it difficult to adapt to regular water cups of different shapes and materials, which limits the actual promotion scenarios such as office gifts.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, while the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0040] like Figures 1 to 2As shown, this utility model provides an energy-saving smart drinking water management coaster with automatic recording function, including an upper shell 11, a lower shell 12, and a weighing sensor 2 disposed between them. The weighing sensor 2 is connected to the lower shell 12 and the upper shell 11 respectively by fixing screw 13 and fixing screw 14. The weighing sensor 2 is used to detect the weight change of the container it supports in real time. A PCB circuit board 3 is installed inside the upper shell 11 by double-sided tape, a limiting bracket, or a slot. The PCB circuit board 3 is sequentially arranged with a main control chip 4, an analog-to-digital converter 5, a reset button 6, an LED reminder 7, and a Type-C charging port 8. The main control chip 4 is connected to the weighing sensor 2 and is used to collect and analyze data and coordinate the operation of various modules. The analog-to-digital converter 5 is used to convert the signal from the weighing sensor 2 into a processable signal. The main control chip 4 is connected to a WiFi communication module, which is used for... The system exchanges drinking water data and control commands with remote terminals (such as client APP or server). The reset button 6 is used to wake up the main control chip 4. The LED reminder 7 is used to output drinking water reminder or status prompt signals. The Type-C charging port 8 is located on the outer edge of the upper shell 11. The PCB circuit board 3 is also equipped with a battery management module, which includes a lithium battery, a power detection unit and a charging management circuit, to power each part and adjust the power consumption according to the working status. The battery assembly 1 is fixedly installed in the lower shell 12 with double-sided tape, limit bracket or card slot. The battery assembly 1 is connected to the battery management module through wires to form a complete power supply path. The Type-C charging port 8 is connected to the battery management module by soldering or ribbon cable, forming a power supply path with the battery management circuit and the battery assembly 1, thereby realizing external power supply and charging functions, and supporting real-time voltage monitoring and overvoltage protection functions.

[0041] like Figures 3 to 5 As shown, both the upper shell 11 and the lower shell 12 are provided with fixing holes 15. The load cell 2 is connected to the upper shell 11 and the lower shell 12 through fixing screws passing through the fixing holes 15. This is also the only mechanical connection structure between the upper and lower shells. In this embodiment, the load cell 2 adopts a long strip-shaped metal strain gauge structure. Its body is arranged vertically on the central axis of the device structure. When the water cup 9 is placed on the coaster, its weight will be transmitted through the upper shell 11 → load cell 2 → lower shell 12 → tabletop, ensuring that the source of sensing data is singular and the force transmission path is stable, thereby improving the accuracy and anti-interference ability of weight change detection. The entire coaster structure does not use edge buckles, studs or interlocking structures. The load cell 2 undertakes the main structural connection and mechanical transmission functions of the upper and lower shells.

[0042] like Figure 6As shown, to improve user accuracy and the weighing recognition precision of the device, a positioning mark ring 10 is provided in the center area of ​​the top of the upper shell 11. The positioning mark ring 10 is a circular groove or printed mark, preferably 30mm in diameter (15mm in radius), used to guide the user to accurately place the cup in the center area of ​​the weighing sensor, avoiding displacement that causes sensing errors, thereby improving the accuracy and consistency of weight detection. To enhance the device's protection against condensation or liquid spillage, an annular flange liquid-blocking ring 17 is provided around the positioning mark ring 10, which adopts an integral injection molding structure, and the outer edge is preferably a rounded corner with a radius of 2mm. The transition design features a chamfered structure on the inner side, preferably with a radius of 2mm, to form a gently sloping liquid barrier area. This effectively guides liquid outflow or limits its diffusion into the circuit area, improving protection reliability without affecting the stability of the water cup 9. An edge limiting ring 16 is provided on the outer perimeter of the upper shell 11. This is a relatively wide circular visual boundary marker structure used to limit the maximum placement range of the cup, guiding users to avoid placing containers that exceed the size on the device surface, ensuring weighing accuracy and equipment safety. The positioning marker ring 10, the edge limiting ring 16, and the annular flange liquid barrier ring 17 work together to guide user operation and ensure stable equipment operation.

[0043] The upper shell 11 of this utility model is the upper pressure-bearing part of the device. It is preferably made of high-gloss ABS material by injection molding, and is disc-shaped with a smooth surface, providing good visual texture and surface finishing effect. To enhance the physical stability of the device in a desktop environment, the bottom outer surface of the lower shell 12 is provided with an injection-molded one-piece anti-slip textured structure, preferably an array of annular raised dots or a diamond grid pattern, to increase the coefficient of friction with the desktop contact surface and adapt to various usage scenarios (such as desktops made of glass, wood, metal, etc.).

[0044] In actual use, the main control chip 4 enters a low-power sleep state by default during operation and is only woken up when any of the following conditions are met:

[0045] 1. A sudden change in the output value of weighing sensor 2 indicates a physical disturbance or a change in the placement of the cup;

[0046] 2. When the preset timed task is reached (such as uploading on the hour or synchronization time);

[0047] 3. The user can manually wake up the device by pressing the physical reset button 6 on the device. The reset button 6 is located in an accessible position on the device casing and is connected to the interrupt pin of the main control chip 4. The chip is woken up by triggering a hardware interrupt.

[0048] After being woken up, the main control chip 4 collects and judges the sensor data. If it is a valid drinking behavior, the following functions are triggered:

[0049] 1. Output flashing or lighting reminder signals via LED lights;

[0050] 2. Cache drinking behavior records locally;

[0051] If the communication module is connected to the network normally, the records will be uploaded to a remote server or the user's app via WiFi. When communication is interrupted, the system will save the records in a local cache, supporting offline data retention and batch upload mechanisms to ensure that data is not lost and to maintain continuous tracking of the user's drinking behavior.

[0052] The above-described solutions are merely descriptions of preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily implemented by those skilled in the art within the scope described in this application without altering the basic principles involved in the claims should be covered within the scope of protection of this application. That is, the scope of protection of this application should be determined by the scope of protection of the claims.
