Description

Technical Field

[0001] This utility model relates to the technical field of drinking water equipment, and in particular to a drinking water equipment that precisely controls the water output. Background Technology

[0002] As people's living standards continue to improve and the demand for diverse functions of drinking water equipment in various specific scenarios increases, the precise control of water output from drinking water equipment has become increasingly urgent. In home settings, when parents prepare formula for infants, they must strictly control the water volume according to a specific ratio, such as 30ml of water to 1 scoop of formula. Traditional drinking water equipment, due to its inherent error margin, may result in inaccurate formula concentration, which could adversely affect the health of infants. In the commercial sector, coffee shops, tea shops, and other establishments also need to precisely control the amount of water added to ensure consistent taste for different beverages (such as Americano and latte).

[0003] However, existing drinking water equipment has many shortcomings in terms of water output control. On the one hand, environmental factors have a significant impact on water output; for example, different ambient temperatures can cause changes in the pump's drive value, leading to fluctuations in water output. On the other hand, while some existing patented technologies attempt to solve the water output control problem, they have obvious flaws. For example, the control method proposed in patent CN120231727A, which combines temperature compensation and dynamic calibration, relies on static fitting for its water output model. This leads to significant errors in nonlinear scenarios, especially at extreme temperatures (such as below 5℃ or above 40℃), where the fitting error increases significantly, resulting in inaccurate calculation of the water output rate. Furthermore, the calibration process requires users to manually input the actual water output, which is cumbersome and prone to human error. If automatic calibration relies on sensors, additional hardware is required, contradicting the design principle of "low cost." For example, patent CN215914173 adds an electromagnetic flow meter inside the water dispenser. The electromagnetic flow meter calculates the amount of water flowing through it to control the start and stop of the water dispensing switch. Although it can achieve a certain degree of accurate water dispensing, the electromagnetic flow meter may be affected by impurities in the water, magnetic fields and other factors, which may lead to measurement errors. If the water contains a lot of ferromagnetic impurities, it will seriously interfere with the measurement accuracy of the electromagnetic flow meter.

[0004] Therefore, developing a drinking water device that can achieve high-precision water output control without being affected by environmental factors such as water temperature and water pressure, and that has a simple implementation process without introducing easily damaged components, is of great practical significance. Utility Model Content

[0005] In view of the above-mentioned problems with existing drinking water equipment, the aim is to provide a drinking water equipment that can accurately control the water output.

[0006] The specific technical solution is as follows: A drinking water device for precisely controlling water output includes a body, a water storage device and a control device mounted on the body, a water receiving platform with a cup holder on the platform, and a water outlet located directly above the cup holder. The control device is connected between the water storage device and the water outlet for controlling the water output. The device also includes: An electronic scale is installed inside the cup holder and has a weighing platform on top to support the cup. The electronic scale has a wireless communication module and is connected to the control device via the wireless communication module to transmit the weight of the water in the cup to the control device so that the control device can control the water output from the outlet.

[0007] As a further improvement and optimization of this solution, it also includes: The water receiving platform has a pull-out groove on its side that communicates with the cup holder. One end of the pull-out platform is slidably disposed in the pull-out groove, and the electronic scale is disposed on the top of the pull-out platform.

[0008] As a further improvement and optimization of this solution, the top of the other end of the pull-out platform has a limiting plate, which can be matched with the side of the water receiving platform for limiting. When the limiting plate is matched with the side of the water receiving platform, the electronic scale is located in the pull-out groove.

[0009] As a further improvement and optimization of this solution, the distance between the top of the weighing platform and the top of the pull-out platform is equal to the distance between the top of the pull-out platform and the top inner wall of the pull-out groove.

[0010] As a further improvement and optimization of this solution, the cup groove is a rectangular groove.

[0014] As a further improvement and optimization of this solution, a placement groove is formed on the top of the weighing platform, and the size of the placement groove is larger than the size of the water cup.

[0015] The positive effects of the above technical solution compared with the existing technology are: (1) By setting an electronic scale with a wireless communication module in the cup slot, this utility model can detect the weight change of the water receiving container in real time and accurately, and transmit the data to the control device quickly, so that the control device can accurately control the water output without being affected by environmental factors such as water temperature and water pressure, thus improving the control accuracy of the water output.

[0022] Figure 1 This is a schematic diagram of the structure of a drinking water device for precisely controlling the water output according to this utility model; Figure 2 This is a flowchart illustrating the water intake process of a drinking water device for precisely controlling water output according to this utility model. Figure 1-2 The figure shows a preferred embodiment of a drinking water device for precisely controlling water output, including a body 1, a water storage device (not shown) and a control device (not shown) on the body 1, a water receiving platform 11 on the body 1, a cup holder 12 on the water receiving platform 11, and a water outlet (not shown) on the body 1, located directly above the cup holder 12. The control device is connected between the water storage device and the water outlet to control the water output. The device also includes an electronic scale 2, which is located in the cup holder 12 and has a weighing platform 21 on its top for supporting the cup. The electronic scale 2 has a wireless communication module and is connected to the control device via the wireless communication module to transmit the weight of the water cup to the control device so that the control device can control the water output.

[0023] In this application, by setting an electronic scale 2 with a wireless communication module in the cup trough 12, the weight change of the water receiving container can be detected in real time and accurately, and the data can be quickly transmitted to the control device. This allows the control device to accurately control the water output, unaffected by environmental factors such as water temperature and water pressure, thus improving the control accuracy of the water output.

[0024] Furthermore, as a preferred embodiment, in order to facilitate the taking and placing of the electronic scale 2, it also includes: a pull-out platform 3, the side of the water receiving platform 11 has a pull-out groove 13 communicating with the cup groove 12, one end of the pull-out platform 3 is slidably disposed in the pull-out groove 13, and the electronic scale 2 is disposed on the top of the pull-out platform 3.

This arrangement allows the electronic scale 2 to be easily removed or placed through the pull-out platform 3.

[0027] Furthermore, as a preferred embodiment, the cup holder 12 is a rectangular groove. The rectangular groove design can better accommodate common shaped water cups, allowing the water cup to be placed stably in the cup holder 12, reducing the impact of water cup shaking on the weighing of the electronic scale 2, improving the stability and accuracy of weighing, and facilitating precise control of the water output.

[0028] Furthermore, as a preferred embodiment, the wireless communication module is NFC. Using NFC wireless communication technology, a stable and reliable wireless connection can be established with the control device. It should be noted that the electronic scale 2 with NFC wireless communication function in this application is an existing mature device, and its specific structure and principles will not be described in detail herein.

[0029] Furthermore, as a preferred embodiment, the water storage device is connected to the water outlet via a water outlet valve, and the control device is electrically connected to the water outlet valve to control the opening and closing of the water outlet valve and the degree of opening. The control device controls the opening and closing of the water outlet valve and the degree of opening through electrical connection, and combined with the weight data transmitted by the electronic scale 2, achieves precise control of the water output, meeting the water output needs of different users.

[0030] Specifically, the water storage device can be a water storage tank, located above the water outlet. The water storage tank is connected to the water inlet of the water outlet valve, and the water inlet and outlet of the water outlet valve are connected by pipes. Furthermore, as a preferred embodiment, the water outlet valve is an electric valve.

[0031] Furthermore, as a preferred embodiment, the top of the weighing platform is formed with a placement groove, the size of which is larger than the size of the water cup, for collecting water that may be accidentally spilled during the water collection process.

[0032] Based on the above, this utility model also has the following embodiments: In the aforementioned drinking water equipment that precisely controls water output, the control device achieves high-precision dynamic adjustment of the water output through the coordinated operation of multiple components, combining real-time data from the electronic scale 2 with a preset algorithm. Its specific control process and principle are as follows: I. Core Components and Data Flow of the Control Device 1. Hardware Architecture Central Processing Unit (CPU): As the control core, it is responsible for data calculation, strategy execution, and instruction generation.

[0033] Storage module: Pre-stores a database of "weight-water conversion relationship" (e.g., 1g water ≈ 1ml) and water outlet valve control strategy (e.g., flow rate-time curve).

[0034] Wireless communication module: Establishes a real-time data connection with the electronic scale 2 and receives weight change signals.

[0035] Control circuit: Connects to the outlet valve and executes the opening / closing and flow rate adjustment commands generated by the CPU.

[0036] 2. Data Flow Path Electronic scale 2 → Control device: Transmits the initial weight of the water container and incremental data during the water filling process in real time via NFC wireless communication.

[0037] Control device → Water outlet valve: Generates control signals based on calculation results to adjust the valve opening degree and opening / closing time.

[0038] II. Control Logic and Procedures 1. Initial Setup Phase User input target volume: Set the target water output volume (e.g., 300ml) via touchscreen or button.

[0039] Empty cup weighing: Electronic scale 2 measures and transmits the weight of the empty container to the control device, which stores it as a reference value.

[0040] Strategy invocation: The CPU retrieves the corresponding target amount of water valve control strategy from the storage module (e.g., flow rate 50ml / s, duration 6 seconds).

[0041] 2. Dynamic control of the water receiving process Real-time weight monitoring: The electronic scale 2 continuously detects the weight increment of the container and transmits it to the control device every second.

[0042] Water volume conversion and error correction: The CPU calculates the current amount of water collected based on the "weight-water conversion relationship" (e.g., each gram increment corresponds to 1 ml of water).

[0043] If a flow rate deviation is detected (such as the actual flow rate being lower than 50ml / s due to water pressure fluctuations), the CPU dynamically adjusts the valve opening or extends the water output time to ensure that the cumulative water volume accurately matches the target value.

[0044] Early termination mechanism: When the calculated remaining water volume is less than the minimum valve adjustment precision (e.g., 5ml), the CPU closes the valve in advance to avoid over-flushing.

[0045] 3. Termination Condition Determination Weight target trigger: When the total weight increment of the container reaches the theoretical weight corresponding to the target amount (e.g., 300g), the CPU immediately sends a stop signal to the water outlet valve.

[0046] Abnormal Handling: If communication between the electronic scale 2 and the control device is interrupted during water dispensing, the CPU will trigger an emergency stop to prevent unlimited water dispensing.

[0047] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
