[0029] The following is combined Figures 1 to 3 The following describes embodiments of the present invention.

[0030] According to an embodiment of the present invention, an electronic scale is provided, comprising: a housing 1, wherein a wireless charging component and a battery 3 are disposed inside the housing 1, the wireless charging component is electrically connected to the battery 3, the wireless charging component includes a wireless magnetron 2, the wireless magnetron 2 cooperates with a wireless charger 10 to charge the battery 3.

[0031] Specifically, the housing 1 is equipped with a wireless charging component and a battery 3. When the electronic scale needs to be charged, the wireless charger 10 is placed at the bottom of the housing 1 and corresponds to the wireless magnet 2 inside the housing 1. The wireless charger 10 has an electromagnetic transmitter with a high-frequency alternating magnetic field. This magnetic field penetrates the housing 1 and induces a current in the wireless magnet 2. The wireless magnet 2 transmits the current to the battery 3 to complete the charging of the battery 3.

[0032] By setting up a wireless charging component and battery 3 inside the housing 1, wireless charging of battery 3 is achieved, eliminating the need for a wired charging interface in the housing 1. This avoids the problems of corrosion and liquid infiltration that wired charging interfaces are susceptible to in humid environments, greatly improving the reliability and safety of the electronic scale in humid environments and extending the lifespan of the electronic scale.

[0033] In one embodiment, a weighing pan 4 is also included, which is disposed above the housing 1. The weighing pan 4 has a weighing sensor 5, which is disposed inside the housing 1 and is electrically connected to the battery 3.

[0034] Specifically, such as Figures 1 to 3 As shown, the weighing pan 4 is positioned above the housing 1. The upper surface of the weighing pan 4 has a weighing position. The weighing sensor 5 is positioned at the bottom of the weighing pan 4. The weighing sensor 5 can accurately sense the weight of the item on the weighing position. One end of the weighing sensor 5 penetrates the side wall of the housing 1 and extends into the housing 1. The weighing pan 4 is fixedly connected to the housing 1 through the weighing sensor 5. The weighing sensor 5 is connected to the battery 3, and the battery 3 can supply power to the weighing sensor 5.

[0035] The weighing sensor 5 is independently installed at the bottom of the weighing pan 4 and extends into the housing 1. It is directly connected to the battery 3, which not only ensures the accuracy of weighing, but also enables the device to operate independently by being directly powered by the battery 3 without the need for an external power cord, thereby effectively reducing the risk of circuit aging in humid environments.

[0036] In one embodiment, the connection between the weighing sensor 5 and the housing 1 has a sealing structure.

[0037] Specifically, the sealing structure (not shown) is structural adhesive, which fills the gap between the load cell 5 and the side wall of the housing 1, forming a tight waterproof barrier. The structural adhesive effectively prevents moisture or liquid in humid environments from seeping into the housing 1 through the connection, avoiding short circuits or corrosion of electrical components caused by liquid intrusion, and further improving the stability and durability of the electronic scale in humid environments.

[0038] In one embodiment, the housing 1 has a control structure 6, the battery 3 is electrically connected to the control structure 6, and the weighing sensor 5 is electrically connected to the control structure 6.

[0039] Specifically, such as Figure 3 As shown, battery 3 is electrically connected to control structure 6, thereby supplying power to control structure 6. Weighing sensor 5 is also electrically connected to control structure 6. Weighing sensor 5 transmits the weight data of the items on the weighing position to control structure 6. Control structure 6 acquires this information, processes and analyzes it, and transmits the data to a host computer or display for observation by relevant personnel. Preferably, control structure 6 is a circuit board containing code to implement the above functions.

[0040] The control structure 6 is integrated into the housing 1 and is directly powered by the battery 3, which avoids the problem of external power lines being susceptible to corrosion in humid environments. At the same time, the direct connection between the weighing sensor 5 and the control structure 6 ensures the stability and real-time performance of data transmission, effectively improving the overall performance and reliability of the electronic scale.

[0041] In one embodiment, a display structure 7 is provided on the housing 1, and the control structure 6 is electrically connected to the display structure 7. The display structure 7 is used to display the weight of the items on the weighing pan 4 and the power of the battery 3.

[0042] Specifically, such as Figure 3 As shown, the display structure 7 is embedded in the outer surface of the housing 1. Its display interface is clear and easy to read, and the connection between the display structure 7 and the housing 1 also has a waterproof sealing structure. The control structure 6 transmits the processed weighing data and the battery power information of the battery 3 to the display structure 7. The display structure 7 displays the weight of the item and the remaining power of the battery 3 intuitively through an LED display screen or LCD screen, which makes it convenient for staff to obtain key information in real time, know the weight of the item on the weighing position and the battery power, facilitate accurate beverage proportioning and timely battery charging, improve work efficiency, and enhance the practicality and convenience of the electronic scale.

[0043] In one embodiment, the housing 1 is disposed inside the cavity of the water receiving tray 8, and the upper end face of the water receiving tray 8 is provided with a through hole 9 communicating with the cavity, and the weighing pan 4 is adapted to extend out of the cavity from the through hole 9.

[0044] Specifically, such as Figure 1 As shown, the water receiving tray 8 is hollow inside, forming a cavity. The top of the water receiving tray 8 has a drain hole, and the top of the water receiving tray 8 has a through hole 9 for the weighing pan 4 to extend out. The drain hole is located on the outer periphery of the through hole 9. The weighing pan 4 extends out of the cavity from the through hole 9, so that the weighing position is located above the water receiving tray 8, which is convenient for placing the item to be weighed. The water receiving tray 8 can effectively catch any liquid that may drip from the weighing pan 4, such as water droplets or residual liquid splashed during the beverage preparation process.

[0045] In one embodiment, the outer contour of the weighing pan 4 matches the contour of the through hole 9.

[0046] Specifically, such as Figure 1 As shown, the outer edge of the weighing pan 4 is designed to match the shape and size of the through hole 9, such as a round weighing pan 4 corresponding to a round through hole 9, a square weighing pan 4 corresponding to a square through hole 9, etc., so that the weighing pan 4 can be embedded in the water receiving tray 8 for use, which not only ensures a simple and harmonious appearance, but also accurately adapts to the tea-making scene and avoids interference from surrounding liquids.

[0047] In one embodiment, the housing 1 includes an upper housing 101 and a lower housing 102. Both the upper housing 101 and the lower housing 102 have grooves. The grooves of the upper housing 101 and the lower housing 102 cooperate with each other to form a mounting cavity. The wireless charging component and the battery 3 are disposed in the mounting cavity.

[0048] Specifically, such as Figure 3As shown, the upper housing 101 and lower housing 102 are made of ABS plastic. They are fixed together by ultrasonic welding, forming a sealed mounting cavity that effectively prevents moisture or liquid from entering the interior in humid environments, protecting the wireless charging components and battery 3 from corrosion and short circuits. ABS plastic material has excellent impact resistance, heat resistance, and corrosion resistance, meeting the special requirements of the beverage equipment's operating environment. The ultrasonic welding process achieves a seamless connection between the upper and lower housings 102, ensuring not only the overall structural stability but also further improving waterproofing, ensuring long-term stable operation of the electronic scale in humid environments.

[0049] According to an embodiment of the present invention, another aspect provides a beverage device, including an electronic scale, wherein the electronic scale is the same as the one described in the above embodiment.

[0050] Furthermore, the beverage equipment also includes a main unit and multiple peristaltic pump modules. The main unit connects to each peristaltic pump module via a 485 bus. Each peristaltic pump module is responsible for conveying a specific material, and the main unit precisely controls the output of each peristaltic pump module by sending pulse commands. The main unit has a human-machine interface and an operating system, with the operating system integrated into the human-machine interface, allowing operators to run the operating system through the human-machine interface. The electronic scale has a Bluetooth communication unit, which enables wireless communication between the electronic scale and the main unit. Preferably, the Bluetooth communication unit uses the BLE communication protocol. When the main unit and the electronic scale are connected for the first time, the main unit and the weighing module will perform a one-time secure pairing process to establish a reliable connection. Thereafter, each time the equipment is powered on, the main unit will automatically scan and connect to the paired weighing module.

[0051] The host computer can send commands to the electronic scale, including: CMD_TARE: Commands the electronic scale to zero its current reading and establish a weighing reference.

[0052] CMD_GET_STABLE_WEIGHT: Requests a stable weight reading. Upon receiving this command, the scale continuously monitors weight changes until the reading fluctuates below a threshold within a preset time period, at which point it returns the stable value. This avoids inaccurate readings caused by liquid sloshing.

[0053] CMD_GET_STATUS: Queries the status of the electronic scale, such as battery level and connection status.

[0054] The electronic scale responds to the host's requests via a characteristic from the GATT (Generic Attribute Profile) service of the BLE communication protocol. The data can be encapsulated in a lightweight data format, such as a JSON string. A typical data packet might look like this: {"status": "stable", "weight_grams":20.15, "battery_pct": 85}.

[0055] Furthermore, the beverage equipment has an automatic calibration function, the steps of which are as follows: S1: Start-up process: The operator selects the "Automatic Calibration" function on the human-machine interface and can select multiple or all of the corresponding material channels that need to be calibrated.

[0056] S2: System preparation: The host sends the CMD_TARE command to the electronic scale via the BLE communication protocol to tare and zero the electronic scale, establishing an accurate zero-point reference.

[0057] S3: First Calibration Point (Discharge and Stop): Based on the currently stored calibration parameters for a specific channel, the host computer calculates the number of pulses required for the peristaltic pump to output a lower target weight (e.g., 20 grams), and commands the peristaltic pump of that channel to discharge material via the 485 bus. The peristaltic pump stops immediately after the target number of pulses is reached.

[0058] S4: First Weighing (Stabilization and Data Acquisition): After the peristaltic pump stops, the host waits a moment for the liquid to stabilize, then sends the CMD_GET_STABLE_WEIGHT command to the scale. After the scale internally completes the reading stabilization judgment, it sends the measured actual weight (e.g., 19.8 grams) to the host via the BLE communication protocol. The host records the first set of data points: (Target Pulse Count 1, Actual Weight 1).

[0059] S5: The host automatically repeats steps S2 to S4, but uses medium (e.g., target 50 grams) and high (e.g., target 100 grams) target weights, and collects two additional sets of data points through a "stop-stabilize-weigh-calculate" cycle: (target pulse count 2, actual weight 2) and (target pulse count 3, actual weight 3).

[0060] S6: Parameter Calculation and Model Update: The host computer uses three or more sets of collected data points to execute a regression algorithm (e.g., least squares linear regression) to calculate a new "pulses per gram" coefficient that more accurately reflects the current peristaltic pump performance. This calibration model based on multi-point fitting ensures higher accuracy for the peristaltic pump across the entire commonly used discharge range, compared to single-point deviation compensation in the comparison file.

[0061] S7: The newly calculated calibration coefficients are written to the host's non-volatile memory (such as Flash or EEPROM), overwriting the old parameters associated with the channel.

[0062] S8: Process Complete: The human-machine interface displays a "Calibration Complete" message. If multiple channels are selected, the system will automatically continue to perform calibration for the next channel until all are completed.

[0063] Apart from the initial startup, the entire calibration process requires no manual intervention, which greatly saves employees' time and energy, improves work efficiency, and reduces errors and operational mistakes that may be caused by manual calibration.
