Abstract
Description
Technical Field
[0001] This invention relates to the field of drinking water equipment technology, specifically a one-button water dispensing tea bar machine. Background Technology
[0002] Tea bar machines, as convenient drinking water devices, are widely used in various scenarios such as homes, offices, and teahouses. Their core function is to realize the storage, heating, cooling, and water dispensing control of bottled water, providing users with drinking water at different temperatures. As people's living standards improve, users have put forward higher quality requirements for the convenience, accuracy, and safety of tea bar machines.
[0003] Currently, there are many types of tea bar machines on the market, and related technologies are constantly being optimized. For example, a tea bar machine with publication (announcement) number CN114052495A achieves universal assembly of warm and cold door shells by reserving buckles and reinforcing ribs in the door shell. The cold cabinet is foamed separately and then assembled with the machine body, solving the problem of incompatibility between the overall foaming process tea bar machine and the warm tea bar machine. At the same time, it ensures the refrigeration and heat preservation effect. However, its core improvement is concentrated on the assembly structure of the machine body and door and the adaptation of the refrigeration function. It does not involve key technical points such as the convenience of water dispensing operation, the accuracy of temperature and flow control, and the design to prevent accidental touch. The water dispensing operation still follows the traditional cumbersome process, and the layout of functional modules has not been optimized, which has the potential problems of large internal space occupation and messy wiring.
[0004] Another patent, CN107853994A, describes a tea bar machine. This patent achieves flexible switching between moving and fixed modes by setting a floating support plate, guide rod, and return spring in the water tank's accommodating cavity. It also optimizes the faucet's anti-misoperation structure and the inlet pipe's dust cover design, reducing the risk of misoperation and bacterial entry, and improving safety and water quality. However, this patent also fails to address the core defects of cumbersome water dispensing operation and low temperature and flow control accuracy. Water dispensing requires rotating the faucet to switch the circuit, making the operation process complex. Furthermore, it lacks a coordinated control mechanism for temperature and flow, resulting in significant fluctuations in water temperature and flow rate. Additionally, it lacks modular design, has poor functional expandability, and is difficult to adapt to the personalized needs of different scenarios.
[0005] In addition to the shortcomings of the two comparative documents mentioned above, existing tea bar machines still have many common technical defects: the water dispensing operation is often cumbersome, with some products requiring users to press buttons and adjust parameters multiple times to dispensing water, making them unsuitable for elderly people, children, and other people with weaker operational abilities. Furthermore, some tea bar machines lack anti-accidental touch design for the water dispensing buttons, which can easily lead to water waste or equipment malfunction due to accidental touches. In terms of temperature and water output control, existing tea bar machines mostly use single temperature control or single flow control methods, lacking the coordinated operation of the two, resulting in large fluctuations in water temperature and difficulty in accurately controlling the water output, which can easily lead to problems such as water that is too hot, too cold, or overflowing. The core functional modules are mostly laid out in a decentralized manner, which not only occupies a lot of internal space but also easily leads to a high failure rate of equipment operation due to messy wiring, making maintenance inconvenient.
[0006] In view of the deficiencies in the existing technology and comparative documents, there is an urgent need to develop a one-button water dispensing tea bar machine that can solve the above problems, achieve one-button accurate water dispensing, stable temperature and flow control, reasonable module layout, comprehensive safety protection and high space utilization, so as to fill the gap in the existing technology and meet the needs of the market and users.

Detailed Implementation
[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0024] The one-button water dispensing tea bar machine of the present invention integrates various functional modules into the operating table 20 and the control console 30, and with the temperature-flow dual closed-loop collaborative control algorithm, it realizes one-button accurate water dispensing, multi-mode heating, and full-process safety protection. At the same time, it adapts to the operating habits of different people, improving the convenience and safety of use. Its specific implementation is as follows.
[0025] like Figure 1 As shown, the one-button water dispensing tea bar machine of the present invention includes a tea bar machine body 10. The tea bar machine body 10 serves as an integral installation carrier and has a three-layer structure from the outside to the inside. It is made of stainless steel, a foamed anti-epidemic layer, and 304 stainless steel in one piece. The foamed anti-epidemic layer is made of PU foam, which effectively ensures a long water quality cycle and makes drinking water healthier. It has a rectangular structure, which is convenient to place on the table or floor in home, office and other scenarios. The upper part is fixedly equipped with an operating table 20, a control console 30 and a back seat 40. The three are connected to the tea bar machine body 10 by a snap-fit, which is convenient for disassembly and maintenance. A sealing ring is set at the connection to improve the overall sealing performance.
[0026] The backrest 40 is vertically fixed to the upper rear end of the tea bar machine body 10. Two preset installation positions are symmetrically arranged on its left and right sides for fixing two one-touch water dispensing buttons 41. The one-touch water dispensing buttons 41 adopt a press-type self-resetting anti-accidental touch structure. The button travel is set to 3-5mm to adapt to the pressing habits of people with different operating abilities, such as the elderly and children, and avoid inconvenience caused by excessive or insufficient pressing travel. The button surface is integrally molded with anti-slip texture to increase the friction when pressing and prevent hand slippage. At the same time, the button adopts a waterproof and dustproof sealing structure with a protection level of IPX4, which can effectively prevent water stains and dust from entering the button and extend its service life.
[0027] like Figures 2-5 As shown, the control panel 20 and control console 30 integrate an input command module 1, a main controller module 2, a function execution module 3, a display module 4, a protection module 5, a power supply module 6, and a sensor detection module 7. These modules are connected via PCB circuit boards, resulting in a rational layout that saves installation space and reduces the risk of malfunctions caused by messy wiring. The specific structure and working principle of each module are as follows: The input instruction module 1 is integrated inside the console 30 and uses an STM32F103 microcontroller as the core control chip. Its input terminal is electrically connected to the one-button water dispensing button 41 to collect the trigger signal of the one-button water dispensing button 41 in real time, and convert the collected button command into an electrical signal and transmit it to the main controller module 2. At the same time, the input instruction module 1 can be expanded to connect to the voice control unit and the double-click sensing unit to realize multiple command input methods and improve the convenience of operation.
[0028] The main controller module 2 is integrated inside the console 30 and is electrically connected to the input instruction module 1, the sensor detection module 7, the function execution module 3, the display module 4, the protection module 5, and the power supply module 6. As the control core of the entire tea bar machine, it adopts the STM32F407 microcontroller, which has the characteristics of fast computing speed, high control accuracy, and strong anti-interference ability.
[0029] The main controller module 2 has a built-in temperature-flow dual closed-loop collaborative control algorithm. This algorithm integrates the PID temperature adjustment formula and the flow calculation algorithm, which is one of the core technologies of this invention. Most existing tea bar machines use single temperature control or single flow control, which cannot achieve the collaborative linkage of the two. This invention, through this dual closed-loop algorithm, can dynamically adjust the operating status of the function execution module 3 according to the real-time water temperature and water output, so as to achieve precise control.
[0030] The PID temperature control formula is as follows: ; In the formula, u(t) is the drive power output by the main controller. This is a proportionality coefficient, with a value ranging from 0.5 to 2.0. To set the difference between the set water temperature and the real-time water temperature; The integral time constant has a value ranging from 10 to 30 s; The differential time constant has a value ranging from 1 to 5 seconds; it can be adjusted... , , These three parameters enable rapid and stable control of water temperature, preventing excessive temperature fluctuations.
[0031] The formula for the flow calculation algorithm is: ; In the formula, Q is the real-time water output, in L / min; ΔP is the flow coefficient, with a value ranging from 0.8 to 1.2, preset according to the model of the water intake unit; ΔP is the pressure difference between the inlet and outlet of the water intake unit, in Pa, which is collected in real time by the sensor detection module 7; ρ is the density of water, with a value of 1000 kg / m³; the main controller module 2 uses this formula to convert the pressure difference data collected by the sensor detection module 7 into the real-time water output, thereby realizing accurate monitoring and control of the water output.
[0032] The function execution module 3 is integrated inside the operating console 20 and the control console 30. It includes a heating unit, a cooling unit, and a water intake unit. In some embodiments, a heat preservation unit and an ultraviolet disinfection unit can be added. Each unit is electrically connected to the main controller module 2, receives the drive instructions from the main controller module 2, and executes the corresponding working actions.
[0033] The heating unit uses a stainless steel heating tube with an adjustable power range of 500-1500W. It is installed in the heating zone inside the operating table 20 to heat the water. The cooling unit uses a semiconductor cooling chip and is installed in the cold water zone inside the operating table 20 to cool the water to 5-25℃. The water dispensing unit uses a miniature booster pump, installed inside the operating table 20, and connected to the bottled water in the water tank cabinet 12 at the bottom of the tea bar machine body 10 to draw water and dispensing it. Both the heating and cooling units use DC low-noise devices with an operating noise of ≤35dB, improving the user experience.
[0034] The sensor detection module 7 is integrated inside the control panel 20 and includes a temperature sensor and a pressure sensor. In some embodiments, a water level detection submodule and a leakage detection submodule can be added. Each sensor is bidirectionally electrically connected to the main controller module 2 to collect various operating data in the tea bar machine in real time and feed them back to the main controller module 2 to provide data support for the dual closed-loop control algorithm.
[0035] The temperature sensor uses a PT100 platinum resistance sensor, which is installed on the water pipes between the heating and cooling units to collect real-time water temperature data. The measurement range is 0-100℃, and the measurement accuracy is ±0.5℃. The pressure sensor is installed at the inlet and outlet of the water intake unit to collect the pressure difference ΔP between the inlet and outlet. The measurement range is 0-0.1MPa, and the measurement accuracy is ±0.001MPa. The collected data is processed by the signal conditioning circuit of the sensing and detection module 7 and then transmitted to the main controller module 2.
[0036] The display module 4 is integrated inside the control panel 20 and the control console 30. It includes a touch display sub-screen and LED status indicators. The touch display sub-screen is embedded in the middle of the control panel 20 and uses a 5-inch IPS touch screen. It is electrically connected to the main controller module 2 and is used to visually display the set temperature. Real-time water temperature The device displays real-time water output (Q), equipment operating mode, disinfection status, and other information. It also supports users to manually input and set the temperature and switch operating modes. The LED status indicator is integrated on the side of the control panel 30 and features three colors: blue, red, and green. Blue indicates cold water mode, red indicates heating mode, and green indicates heat preservation mode. In case of abnormal conditions, the indicator flashes at different frequencies to provide an alarm, making it easy for users to quickly identify the equipment status.
[0037] The control console 30 is also equipped with a temperature display screen 31, which is an LED high-definition digital display screen that is linked in real time with the sensing module 7 to display the temperature synchronously. and The display accuracy is ±0.5℃, allowing users to quickly view water temperature information without operating the touch display sub-screen.
[0038] The protection module 5 is integrated inside the control console 30 and electrically connected to the main controller module 2 and the power supply module 6. It includes over-temperature protection submodules, over-current protection submodules, water leakage protection submodules, and low water level protection submodules, providing safety protection throughout the entire equipment operation process. When the real-time water temperature is fed back by the sensing module 7... When the temperature exceeds the preset safety threshold (105℃), the over-temperature protection submodule is triggered and immediately cuts off the power supply to the heating unit to prevent dry burning or overheating damage to the equipment. When the overcurrent protection submodule detects that the circuit current exceeds the preset threshold (5A), it immediately cuts off the power supply to the power module 6 to prevent short circuit damage to the module. When the water leakage detection submodule detects water leakage at the water connection or the water level detection submodule detects that the water level is lower than the preset threshold, it immediately cuts off the power supply output of the power module 6 and controls the display module 4 to issue an audible and visual alarm to remind the user to handle the situation in time.
[0039] Power module 6 is integrated inside console 30. It uses an AC-DC converter, providing AC220V to DC24V / DC5V conversion, supplying stable DC power to all modules including input command module 1, main controller module 2, function execution module 3, display module 4, protection module 5, and sensor detection module 7. Power module 6 also features quadruple protection against overvoltage, overcurrent, overload, and short circuit, ensuring stable operation of all modules and extending equipment lifespan. Main controller module 2 allocates drive power to each unit of function execution module 3 based on a power allocation algorithm. The power allocation algorithm formula is: ; In the formula, Punit is the power allocated to a single unit, Ptotal is the total output power of the power module (value is 2000W), and Tmax is the maximum heating temperature of the tea bar machine (value is 100℃). Through this formula, the power of the heating unit can be dynamically allocated according to the difference between the set temperature and the real-time temperature, so as to achieve energy saving and consumption reduction while improving the temperature control accuracy.
[0040] The lower part of the tea bar machine body 10 is equipped with a storage cabinet 11 and a water bucket cabinet 12, arranged in an upper and lower structure. The storage cabinet 11 is located above the water bucket cabinet 12 and is embedded in the lower inner side of the tea bar machine body 10. The interior of the storage cabinet 11 has detachable and height-adjustable layered shelves for storing tea sets, water cups, tea canisters, and other items. The cabinet door adopts a magnetic silent opening and closing structure, which is noiseless when opening and closing and has good sealing performance. The water bucket cabinet 12 is located at the bottom of the tea bar machine body 10 and is an embedded sealed structure, which is suitable for 5L-18L bottled water. The bottom of the cabinet is equipped with an anti-tipping buckle and a water leakage sensor. The water leakage sensor is electrically connected to the protection module 5. When the water leakage protection is triggered, the display module 4 will simultaneously display an alarm interface. Each of the four corners of the bottom of the tea bar machine body 10 is equipped with a shock-absorbing support foot 13. The shock-absorbing support foot 13 is made of silicone and has anti-slip texture on the bottom, which can effectively reduce the vibration and noise of the equipment during operation and ensure the stability of the equipment.
[0041] When using the device, first place the bottled water into the water tank 12, connect the water pipe, and connect the mains power supply to the power module 6. The power module 6 completes the AC-DC conversion to power each module, and the device enters the standby state. The LED status indicator of the display module 4 is solid green, and the temperature display screen 31 displays the current ambient temperature.
[0042] When the user needs to dispense cold water, they press the blue one-button water dispensing button 41 on the left side of the backrest 40. The input command module 1 collects the cold water dispensing command and transmits it to the main controller module 2. The main controller module 2 drives the cooling unit of the function execution module 3 to work in coordination with the water dispensing unit. The cooling unit cools the water to a preset room temperature or low temperature, and the water dispensing unit draws the water flow and discharges cold water from the water outlet of the control panel 20. At the same time, the sensor detection module 7 collects the real-time water temperature. The water intake flow rate data is fed back to the main controller module 2. The main controller module 2 calculates the real-time water output Q using a flow calculation algorithm and displays it synchronously on the display module 4. When the user releases the button or the real-time water output Q reaches the preset threshold (2L), the main controller module 2 cuts off the power supply to the water intake unit and the cooling unit, stops water output, and the equipment returns to standby mode.
[0043] When a user needs hot water, they first input the set temperature through the touch screen 32 of the control panel 30. (Range 25℃-100℃, adjustment step 1℃). After setting, press the red one-button water dispensing button 41 on the right side of the back seat 40. The input command module 1 collects the heating-linked water dispensing command and transmits it to the main controller module 2. The main controller module 2 drives the heating unit and water dispensing unit of the function execution module 3 to work according to the preset heating and water dispensing mode: If it is mode one (water dispensing and heating simultaneously), the water dispensing unit starts dispensing water first, and the heating unit starts synchronously. The main controller module 2 adjusts the temperature according to the feedback from the sensor detection module 7 using the PID temperature adjustment formula. and The difference e(t) is used to dynamically adjust the driving power u(t) of the heating unit until... achieve The heating unit switches to heat preservation mode and continuously discharges hot water; if it is mode two (preheating and rapid discharge), the main controller module 2 first drives the heating unit to preheat the water to the specified temperature. The system maintains a heat preservation state before driving the water intake unit to discharge hot water, achieving rapid water heating. During the water heating process, the sensor detection module 7 collects data in real time, and the protection module 5 monitors the equipment status in real time. If an abnormality occurs, the protection mechanism is immediately triggered to stop the equipment operation and sound an alarm.
[0044] To more clearly demonstrate the specific implementation of the present invention, and in consideration of the needs of different usage scenarios, two sets of differentiated embodiments are provided below, corresponding to the basic practical version and the upgraded multi-functional version, respectively. Both sets of embodiments are based on the core structure and technical principles of the above specific implementation methods, and differ only in functional configuration and detailed design, so as to reflect the practicality, adaptability and scalability of the present invention.
[0045] This embodiment is the basic model, fulfilling the core functions of one-button water dispensing and precise temperature and flow control. Its specific structure is as follows: The main body 10 of the tea bar machine is made of ABS flame-retardant material. The upper part is fixedly equipped with the operating table 20, the control panel 30 and the back seat 40. Two one-button water dispensing buttons 41 are symmetrically installed on the left and right sides of the back seat 40. The blue button corresponds to cold water and the red button corresponds to hot water. The buttons adopt a press-type self-resetting anti-accidental touch structure with a stroke of 4mm. The surface is provided with anti-slip embossing and the protection level is IPX4.

These modules are connected via a PCB circuit board.

During the operation of the device, the protection module 5 monitors in real time to avoid over-temperature and over-current faults, and the display module 4 displays the device status simultaneously.
[0049] This embodiment is an upgraded version. Based on embodiment 1, it adds voice control, double-tap control, ultraviolet disinfection, and all-dimensional protection functions to improve convenience and safety. The specific structure is as follows: The main body 10 of the tea bar machine is made of ABS flame-retardant material. The upper part is fixedly equipped with the operating table 20, the control panel 30 and the back seat 40. Two one-button water dispensing buttons 41 are symmetrically installed on the left and right sides of the back seat 40. The structure is the same as that of Embodiment 1. A double-click sensing unit is added to the side of the operating table 20. It adopts a capacitive touch design. Double-clicking triggers the start and stop of water dispensing to avoid accidental touch by children.
[0050] The modules integrated within the control panel 20 and control console 30 are optimized based on Embodiment 1: Input command module 1 integrates a voice control unit with a built-in noise-canceling microphone and Chinese voice recognition chip, with an effective recognition distance of ≤3 meters. It supports voice commands such as "dispense cold water," "dispense hot water," "stop water dispensing," and "adjust temperature to XX℃," and has the ability to resist environmental noise interference; Main controller module 2 optimizes the dual closed-loop algorithm parameters, with Kp=1.5, Ti=15s, and Td=2s in the PID temperature adjustment formula and Kv=1.1 in the flow calculation algorithm, improving the calculation speed by 30%; Function execution module 3 adds a heat preservation unit and an ultraviolet disinfection unit.

The water bucket cabinet 12 is located at the bottom and is suitable for 5L-18L bottled water. A water leakage sensor is added to the bottom and is electrically connected to the protection module 5. When a water leakage is triggered, the display module 4 will pop up an alarm interface and sound and light alarms. The shock-absorbing support feet 13 at the bottom of the tea bar machine body 10 are optimized to be made of thickened silicone material, which improves the noise reduction effect and the working noise is ≤30dB.
[0052] Working principle: After power is connected, the device is in standby mode. Users can control water dispensing in three ways: press the one-button water dispensing button 41, double-click the double-click sensing unit on the side of the control panel 20, or issue a voice command. When dispensing hot water, users can select mode two (preheating and quick dispensing) via the touch screen 32 to quickly dispense hot water, while the heat preservation unit maintains a stable water temperature. Before and after each water dispensing, the ultraviolet disinfection unit automatically starts disinfection to ensure the hygiene of the dispensed water. During device operation, the sensor detection module 7 collects water level, leakage, water temperature, and flow data in real time, and the protection module 5 monitors in real time. If abnormalities such as low water level, leakage, overheating, or overcurrent occur, the power is immediately cut off, triggering an audible and visual alarm. The display module 4 synchronously displays the disinfection status, real-time data, and device status. Users can adjust the temperature and switch modes via the touch screen or voice commands, making operation convenient.

At the same time, the temperature-flow dual closed-loop collaborative control algorithm built into the main controller module 2 integrates PID temperature adjustment and flow calculation algorithms to achieve precise linkage control of real-time water temperature and water output, effectively improving the shortcomings of low temperature and flow control accuracy in existing tea bar machines.
[0055] This invention, through the establishment of a comprehensive protection module 5, integrates multiple protection sub-modules such as over-temperature, over-current, water leakage, and low water level protection. Combined with the real-time data feedback from the sensing and detection module 7, it can achieve full-process safety protection for the equipment, avoiding damage to the equipment due to abnormal conditions such as overheating, short circuits, and water leakage, while also preventing users from suffering safety risks due to equipment malfunctions.
