TECHNICAL FIELD

[0002] A beverage preparation equipment is a kind of equipment for making and processing various beverages (such as coffee, tea, juice, soy milk, milkshake, etc.). Taking a coffee machine as an example, the height of the liquid outlet of the coffee machine affects the coffee production effect and the use experience. At present, most coffee machines use sensors to detect the height of the cup and then control the lifting of the liquid outlet. This method often uses infrared, laser or ultrasonic sensors to measure the height of the cup by emitting signals and receiving reflected signals. However, in actual application, on the one hand, cups made of different materials will interfere with the reception of sensor signals due to their different surface reflection characteristics, resulting in detection deviation; on the other hand, environmental factors will also cause the sensor detection data to be inaccurate. Low detection accuracy will lead to poor matching between the liquid outlet and the height of the cup, resulting in problems such as coffee splashing and uneven liquid output, which not only affects the user experience but also causes coffee waste, and it is difficult to meet the user's demand for high-quality coffee production.

[0023] The technical solution provided by this invention has at least the following advantages: The present invention provides a method for adjusting the dispensing device of a beverage preparation equipment. First, the weight of the container is obtained. Before dispensing, the dispensing device is controlled to move from its initial position towards the side closest to the container. During the movement of the dispensing device, the container is weighed in real time using a weighing unit to obtain a first detected weight. The pressure change of the dispensing device on the container is detected using the container's weight and the first detected weight. Using pressure contact as the basis for determining the relative position of the dispensing device and the container, position sensing is achieved through physical contact, avoiding the cumulative error of indirect height detection. This allows the dispensing device to be precisely adjusted to a position suitable for the container opening, thus preventing coffee spillage and uneven dispensing. Simultaneously, the position is dynamically adjusted based on the actual contact pressure between the dispensing device and the container. Containers of different sizes and shapes can be adaptively matched through pressure feedback, improving the compatibility of the beverage preparation equipment with various containers. Furthermore, using the existing weighing unit of the beverage preparation equipment for weight detection eliminates the need for additional sensing elements, simplifying the structure of the equipment. Moreover, the weighing unit can be used to adjust the position of the dispensing device and the dispensing volume, forming a coherent operating logic and improving the overall coordination and reliability of the equipment.

[0027] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0028] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0029] Beverage and processing equipment 100 is a type of equipment used for making and processing various beverages (such as coffee, tea, juice, soy milk, milkshakes, etc.). The specific form of beverage and processing equipment 100 is not limited; for example, it can be a common coffee machine, soy milk maker, or blender. Beverage and processing equipment 100 can integrate required functions according to actual needs, such as grinding, brewing, heating, and cooling functions.

[0030] The beverage preparation equipment 100 includes a body and a weighing device. The body includes a casing, on which a liquid dispenser is movably mounted. The liquid dispenser has a beverage outlet, which is generally oriented downwards and allows the beverage prepared in the beverage preparation equipment 100 to be discharged outwards.

[0031] The casing typically includes a receiving platform below the dispensing device. This platform is used to support containers such as cups, bottles, bowls, and jars. These containers hold the beverages dispensed from the dispensing device. The receiving platform can be defined by a combination of a box and a grid, depending on the specific needs. The box can be a water collection box, a residue collection box, etc., with no restrictions. The grid serves to filter solid residue and also to stabilize the containers.

[0032] Before dispensing, the dispensing device needs to be adjusted to ensure the optimal height difference between the beverage outlet and the container opening, thus avoiding problems such as coffee splashing and uneven dispensing.

[0033] In order to improve the position adjustment accuracy of the liquid dispenser, the present invention mainly improves the adjustment method of the liquid dispenser. The adjustment method of the liquid dispenser will be described in detail below with reference to the accompanying drawings.

[0034] It should be noted that the weighing part of the weighing device includes a receiving platform and a pressure sensing unit. The receiving platform is generally installed facing upwards, with its top surface used for placing containers, and the pressure sensing unit is installed on it. When the container is placed on the receiving platform, it comes into contact with and is pressed against the pressure sensing unit, allowing the pressure sensing unit to measure the weight of the container.

[0035] The beverage preparation equipment 100 also includes a control device 1. The control device 1 can be built into the housing or placed outside the housing. The control device 1 can be combined with preset in-situ sensors to intelligently identify the real-time weight of the container and the moving position of the dispensing device, so that the dispensing device can be precisely adjusted to a position that matches the opening of the container before dispensing liquid.

[0036] In one embodiment, the beverage preparation equipment 100 also includes a display component electrically connected to the weighing unit to display the measurement results of the weighing unit. The display component can display any suitable information as needed, such as directly displaying the actual measurement data of the weighing unit in real time, displaying correlated data obtained by conversion from the actual measurement data, or displaying the status information of the weighing function of the weighing unit. The display component can be integrated into the weighing device, or it can be separate from the weighing device, for example, externally mounted on the casing.

[0037] Following the above, the user places the container on the receiving platform of the weighing unit. When the weighing unit is in operation, it needs to check whether there is a container on the receiving platform before each adjustment action. When the weight of the empty cup of the container is detected, the system will record the weight of the empty cup. After one adjustment and dispensing of the liquid dispenser is completed, the system will reset the weighing value of the weighing unit to zero.

[0038] In one embodiment, depending on actual needs, the beverage preparation equipment 100 may further include a timer. The timer may be directly electrically connected to the weighing unit, or indirectly associated with the weighing status of the weighing unit through, for example, an electrical connection to the control device 1. The timer is configured to have a timing mode and a non-timing mode. When in timing mode, the timer can record any desired time point and duration during the weighing process of the weighing unit.

[0039] In one embodiment, the beverage preparation device 100 further includes an input module. Some parameters that need to be pre-input can be input using the touch-screen LCD display of the beverage preparation device 100 as the input module. Alternatively, they can be input from connected external devices, such as mobile phones, tablets, laptops, PDAs, etc., forming the input module. In a preferred embodiment, the beverage preparation device 100 is equipped with a touch-screen LCD display, which can selectively display the aforementioned parameters and allows for parameter input via touch.

[0040] The beverage preparation equipment 100 also includes a display and control module. At least the display and control panel of the module is exposed outside the housing for manual operation by the user. The control buttons of the display and control module constitute the aforementioned input module; the display section can display preset numbers, text, and patterns to help the user understand the status of the beverage preparation equipment 100 during parameter calibration, parameter adjustment, and normal operation. The control interface of the display and control module will be described in detail below with reference to the accompanying drawings.

[0041] The control device 1 includes a memory 15, a processor 11, and a debugging program for the beverage preparation equipment 100 stored in the memory 15 and executable on the processor 11. Please refer to... Figure 8 , Figure 8 This is a schematic diagram of the structure of the control device 1 of the hardware operating environment involved in the embodiment of the present invention.

[0042] The control device 1 may include: a processor 11, such as a central processing unit (CPU), a communication bus 12, a user interface 13, a network interface 14, and a memory 15. The communication bus 12 is used to enable communication between these components. The user interface 13 may include a display screen or an input unit such as a keyboard; optionally, the user interface 13 may also include a standard wired interface or a wireless interface. The network interface 14 may include a standard wired interface or a wireless interface (such as a Wi-Fi interface). The memory 15 may be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as a disk storage device. Alternatively, the memory 15 may be a storage device independent of the aforementioned processor 11.

[0043] Based on the different functional configurations of the beverage preparation equipment 100, corresponding sensors and functional modules can be set to measure or monitor the above parameter values ​​and transmit them to the processor 11 in real time or in a predetermined manner to realize various functional combinations between different parameter modules.

[0044] Those skilled in the art will understand that Figure 8 The structure shown does not constitute a limitation on the control device 1, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0045] like Figure 8 As shown, the memory 15, which serves as a storage medium, may include an operating system, a network communication module, a user interface 13 module, and a debugging program for the beverage preparation equipment 100.

[0046] exist Figure 8 In the control device 1 shown, the network interface 14 is mainly used for data communication with the network server; the user interface 13 is mainly used for data interaction with the user; the processor 11 and the memory 15 in the control device 1 of the present invention can be set in the beverage preparation equipment 100. The control device 1 calls the debugging program of the beverage preparation equipment 100 stored in the memory 15 through the processor 11 and executes the liquid dispensing device adjustment method of the beverage preparation equipment 100 provided in the embodiment of the present invention.

[0047] It should be noted that the above-described structural components do not constitute a limitation on the specific form of the beverage preparation equipment 100. In practical applications, the beverage preparation equipment 100 can be an automated beverage preparation equipment 100 that includes all the above-described modules, such as a coffee machine or a soy milk maker, which has grinding, brewing, and weighing functions.

[0048] Please see Figures 1 to 5 The present invention also provides a method for adjusting the liquid dispenser of a beverage preparation device. This beverage preparation device can be any of the beverage preparation devices described in the above embodiments; it can also be other beverage preparation devices.

[0049] The parameter values ​​obtained by the weighing unit can be stored in the memory of the control device, or they can be stored separately and independently in the memory of the control device. Of course, the values ​​can also be obtained by the user by entering them on-site or pre-entering them in the manner described above.

[0050] The above parameters can be preset based on the calibration before use of the beverage preparation equipment, or they can be adjusted in real time during the use of the beverage preparation equipment. Once the preset parameter values ​​are determined and multiple parameter values ​​form a closed loop, any change or modification of any parameter will break the closed loop formed by multiple parameter values, and the settings and calibration will need to be reset.

[0051] Please see Figure 1 , Figure 1 A flowchart illustrating a first embodiment of a liquid dispensing device adjustment method for a beverage preparation apparatus provided by the present invention. In the first embodiment, the liquid dispensing device adjustment method includes: S10: Get the weight of the container; S40: Controls the liquid outlet to move down from its initial position; S50: Obtain the first detected weight of the container; S60: Adjust the control strategy of the liquid dispenser based on its own weight and the first detected weight.

[0052] The beverage dispensing device adjustment method provided by this invention first obtains the weight of the container; before dispensing, the dispensing device is controlled to move downwards from its initial position towards the side closest to the container. During the movement of the dispensing device, the container is weighed in real time using a weighing unit to obtain the first detected weight of the container. The pressure change of the dispensing device on the container is detected by using the weight and the first detected weight. Using pressure contact as the basis for determining the relative position of the dispensing device and the container, physical contact is used to achieve position sensing, avoiding the cumulative error when indirectly detecting height. This allows the dispensing device to be accurately adjusted to a position that matches the container opening, thereby avoiding problems such as coffee splashing and uneven dispensing.

[0053] Meanwhile, the position is dynamically adjusted by the actual contact pressure between the dispenser and the container. Since the actual contact pressure between the container and the dispenser can be detected regardless of the container's height, size, or whether the rim is regular, containers of different sizes and shapes can be adaptively matched through pressure feedback, thereby improving the beverage preparation equipment's compatibility with various containers.

[0054] Furthermore, traditional height detection relies on the coordinated operation of multiple sensors (such as infrared sensors and distance sensors), and requires the preset height data of a large number of different containers for matching calculations. This results in a complex system design and is prone to adjustment failures due to sensor malfunctions or data matching errors. In contrast, the solution of this invention utilizes the existing weighing unit of the beverage preparation equipment for weight detection, eliminating the need for additional sensing elements. This simplifies the structure of the beverage preparation equipment, reduces the amount of data collected, simplifies the data processing flow, lowers the probability of system errors, and improves operational stability. The weighing unit enables adjustments to the position and volume of the dispensing device, forming a coherent operational logic and improving the overall coordination and reliability of the equipment.

[0055] Specifically, step S60, which adjusts the movement strategy of the dispensing device based on its own weight and the first detected weight, includes: S600: Based on its own weight and the first detected weight, obtain the first pressure value generated by the dispensing device on the container; S601: Adjust the control strategy of the liquid outlet based on the first pressure value and the maximum pressure value.

[0056] Understandably, when the dispenser is in its initial position, the weight detected by the weighing unit is the container's own weight. As the dispenser moves downwards towards the side closest to the container, the weighing unit detects the container's real-time weight. When the first detected weight equals the container's own weight, it is determined that the dispenser is not in contact with the container; at this point, the dispenser does not exert pressure on the container, and the first pressure value is 0.

[0057] When the initial detected weight exceeds the container's own weight, it is determined that the dispensing device is in contact with the container. At this point, the dispensing device will exert pressure on the container, with a first pressure value greater than 0. The control strategy of the dispensing device is adjusted based on the first pressure value and the maximum pressure value.

[0058] More specifically, step S601, which adjusts the control strategy of the liquid outlet based on the first pressure value and the maximum pressure value, includes: S6010: When the first pressure value is less than 0, control the liquid outlet to continue moving downward; S6011: When the first pressure value is greater than 0 and less than the maximum pressure value, control the liquid outlet to continue to move downward; S6012: When the first pressure value is greater than or equal to the maximum pressure value, control the liquid outlet to start moving upward to the target position.

[0059] It is understandable that containers made of different materials (such as ceramic cups, glass cups, paper cups, plastic cups, etc.) have different pressure resistance. For example, paper cups and thin plastic cups are relatively fragile, and if too much pressure is applied, the rim may deform or break. On the other hand, ceramic cups and thick glass cups are more pressure resistant and can withstand slightly greater pressure.

[0060] The maximum pressure value can be designed according to the different materials of the container, thus setting a target clamping force for the container. For example, a lower maximum pressure value (e.g., 0.5N) can be set for more fragile containers, while a slightly higher maximum pressure value (e.g., 2N) can be set for more robust containers. In this way, it can not only avoid damage to the container due to excessive pressure, but also expand the equipment's adaptability to various types of containers.

[0061] Furthermore, in actual operation, when the dispenser gets very close to the container, external interference (such as slight shaking of the container or vibration of the equipment) may cause the weighing unit to detect a slight pressure fluctuation, which may be misinterpreted as the dispenser pressing against the container, thus triggering unnecessary position adjustments.

[0062] By setting a maximum pressure value, if the first pressure value is less than the maximum pressure value, it can be determined that the dispenser is contacting the container but not pressing it firmly against it. Only when the first pressure value is equal to or greater than the maximum pressure value can it be determined that the dispenser is pressing firmly against the container. In this way, invalid pressure signals caused by environmental interference or accidental contact can be effectively filtered out, ensuring the reliability of pressure detection and avoiding false triggering of the adjustment logic.

[0063] When the first pressure value is less than the maximum pressure value, the dispenser contacts the container but does not press firmly against it. At this point, the dispenser can be controlled to continue moving downwards towards the side closer to the container. When the first pressure value is equal to or greater than the maximum pressure value, it can be determined that the dispenser is pressing firmly against the container. At this point, the dispenser meets the requirements for position adjustment, and the dispenser can be controlled to move upwards towards the side farther from the container to the target position.

[0064] Understandably, once the dispenser contacts the container, it continues to move downwards. This further increase in the downward pressure distance results in a gradual increase in the pressure exerted by the dispenser on the container, leading to a rise in the pressure detected by the weighing unit. In other words, pressure and downward pressure distance are positively correlated. For containers of the same specifications, the set maximum pressure value corresponds to a maximum downward pressure distance.

[0065] When the first pressure value equals the maximum pressure value, it can be determined that the dispenser has moved down the maximum downward distance and is pressed firmly against the container. At this point, the dispenser meets the requirements for position adjustment. When the dispenser is moved upward to the target position, the relative positional relationship between the dispenser and the container corresponds to a target pressure value. Therefore, the user can first determine a suitable target pressure value based on the container specifications, and then adjust the dispenser according to the target pressure value to bring it to the target position.

[0066] In one embodiment, please refer to Figure 2 , Figure 2 This is a flowchart of a second embodiment of a method for adjusting the dispensing device of a beverage preparation apparatus provided by the present invention. In the second embodiment, step S6012, which controls the dispensing device to move upward to the target position when the first pressure value equals the maximum pressure value, includes: S60121: Controls the upward movement of the liquid outlet; S60122: Obtain the second detected weight of the container; S60123: Based on its own weight and the second detected weight, obtain the second pressure value generated on the container when the liquid outlet moves upward; S60124: When the second pressure value reaches the target pressure value, control the liquid outlet to stop moving upward and maintain it at the target position.

[0067] In this embodiment, after the dispensing device starts to move upward, the weighing unit weighs the container in real time to obtain the second detected weight of the container. The pressure change of the dispensing device on the container is detected by the self-weight and the second detected weight, thereby obtaining the second pressure value generated by the dispensing device on the container when it moves upward. When the second pressure value reaches the target pressure value, the relative position between the dispensing device and the container reaches the target state. That is, the downward pressure distance of the dispensing device is adaptively matched with the characteristics of the container, ensuring that the dispensing device is in the optimal position.

[0068] The present invention does not impose specific restrictions on the target position. In some embodiments, the target position can be set to the position where the liquid outlet slightly touches the container. At this time, the target pressure value is greater than 0, and the liquid outlet will generate a small pressure on the container.

[0069] In another embodiment, the target position can be set to the critical position where the dispenser just contacts the container, at which point the target pressure value is equal to 0, and the dispenser will not exert a small amount of pressure on the container.

[0070] As mentioned above, in actual operation, external interference (such as slight shaking of the container or vibration of the equipment) will affect the detection of the weighing part, causing fluctuations in the detected pressure, which may lead to misjudgment that the liquid outlet has moved down to the maximum downward pressure distance, thus triggering unnecessary position adjustments.

[0071] To avoid misjudgment, in one embodiment, before step S60121 of controlling the liquid dispenser to start moving upward, the following method is further included: S60120: Controls the liquid dispenser to remain in the current position for a preset duration.

[0072] It is understandable that during the contact process between the dispenser and the container, external vibrations, unevenness around the container opening, or fluctuations in the downward movement rate of the dispenser may cause the initial pressure value between the dispenser and the container to reach the maximum pressure value but fail to form a stable seal.

[0073] By maintaining the pressure at its maximum value for a preset duration (e.g., 0.5 to 2 seconds) after the first pressure value reaches its maximum value, such transient interference signals can be filtered out. For example, if the first pressure value remains stable at its maximum value during the dwell period, it indicates that a true and stable contact has been formed between the dispenser and the container. Triggering the upward adjustment action at this time can avoid erroneous operations caused by fluctuating pressure signals and significantly improve the reliability of the judgment logic.

[0074] Meanwhile, for containers of different sizes, when pressed against the dispenser, they will deform (or displace) to varying degrees due to their own elasticity. Setting a preset dwell time allows the container deformation (or displacement) to stabilize, thereby making the pressure detected by the weighing unit closer to the stable value under the actual pressing state. This provides a more accurate benchmark for subsequent upward adjustment, ensuring the compatibility of the final position of the dispenser with the container.

[0075] Furthermore, the downward, stopping, and upward movements of the liquid dispenser are all performed by a drive mechanism (such as a motor, gear set, etc.). If the direction of movement is switched immediately when the first pressure value equals the maximum pressure value (from downward to upward movement directly), impact loads may be generated due to mechanical inertia, causing instantaneous wear on the components of the drive mechanism. Long-term use may affect the lifespan of the equipment.

[0076] By setting a preset dwell time, the drive mechanism can have a buffer time after stopping and moving downwards (for example, the motor can smoothly switch from running to stationary) before starting the upward movement. This can reduce mechanical shock, extend the service life of the core components of the equipment, and improve operational stability.

[0077] Understandably, once the dispensing device is activated and moved to the target position, the dispensing action can begin.

[0078] Please see Figure 1 After step S6012, where the first pressure value equals the maximum pressure value and the liquid outlet is controlled to move upward to the target position, the following steps are also included: S6013: Controls the dispenser to inject beverage into the opening of the container; S6014: Obtain the third detection weight of the container; S6015: Obtain the actual liquid weight of the injected beverage based on the third detection weight and its own weight; S6016: When the actual liquid weight equals the target liquid weight, control the liquid dispenser to stop dispensing liquid; S6017: Control the liquid outlet to move upward to the initial position.

[0079] In other words, in this embodiment, after the dispensing device is activated and moved upwards to the target position, the final position of the dispensing device has a high degree of adaptability to the container. At this time, the dispensing device is controlled to inject beverage into the opening of the container. The container is weighed in real time using a weighing unit to obtain the third detection weight of the container. The weight of the liquid injected into the container by the dispensing device is detected by the self-weight and the third detection weight. When the actual liquid weight equals the target liquid weight, it means that the liquid injection operation is completed, and the dispensing device can be controlled to stop dispensing. Afterwards, the dispensing device can be moved upwards to the initial position.

[0080] To ensure the stability and accuracy of the dispensing device adjustment, in one embodiment, please refer to... Figure 3 , Figure 3 This is a flowchart of a third embodiment of a liquid dispensing device adjustment method for a beverage preparation apparatus provided by the present invention. In the third embodiment, the liquid dispensing device has a first speed, a second speed, and a third speed, wherein the first speed is greater than the second speed, and the third speed is greater than the third speed.

[0081] Step S601, which adjusts the control strategy of the liquid outlet based on the first pressure value and the maximum pressure value, includes: S6017: When the first pressure value is 0, control the liquid dispenser to move downward toward the side closer to the container at a first speed; S6018: When the first pressure value is greater than 0 and less than the maximum pressure value, control the liquid dispenser to move downward towards the side closer to the container at a second speed; S6019: When the first pressure value is greater than the maximum pressure value, control the liquid outlet to move upwards at a third speed toward the side away from the container.

[0082] In this embodiment, when the first pressure value is 0, the dispenser is not in contact with the container and is in the empty stroke stage. By using the fastest first speed to move downward, the distance between the dispenser and the container can be quickly shortened. Especially for containers with low height (shorter empty stroke) or scenarios that require frequent container changes (such as commercial beverage machines), it can significantly reduce invalid waiting time and improve the overall efficiency of beverage preparation per batch.

[0083] When the first pressure value is greater than 0 and less than the maximum pressure value, the dispenser has contacted the container but has not yet made full contact. It then moves downwards at a second speed, slower than the first speed, to avoid instantaneous impact caused by high-speed contact. This avoids container deformation or breakage due to impact and also reduces wear on the dispenser caused by collision with the container, extending the life of the component.

[0084] When the first pressure value is greater than the maximum pressure value, the dispenser presses against the container. It then moves upward at a third speed slower than the first speed to avoid overshooting caused by rapid upward movement (such as the dispenser moving too far upward due to inertia, causing it to exceed the target position). This ensures that the dispenser accurately stops at the target position, thus enabling fine-tuning.

[0085] Thus, during the empty stroke phase, the dispensing device moves downward at high speed, reducing the impact of external interference on the timing of contact (the shorter the time before contact, the smaller the window for environmental interference). After the dispensing device contacts the container, the speed is adjusted to low, allowing the pressure to rise slowly with the displacement. This facilitates the control system's real-time monitoring of pressure changes and allows for early prediction of whether the maximum pressure value is approaching, reducing the probability of overpressure upon contact. After the dispensing device is in contact with the container, the dispensing device moves upward at low speed, allowing the pressure to drop slowly to the target pressure value. This not only ensures the accuracy of the position adjustment but also makes the entire adjustment process smoother.

[0086] It should be noted that steps S6017~S6019 and steps S6010~S6011 can be performed in one step. Steps S6012~S6016 follow steps S6017~S6019.

[0087] In one embodiment, please refer to Figure 4 , Figure 4 This is a flowchart of a fourth embodiment of a dispensing device adjustment method for a beverage preparation apparatus provided by the present invention. In this fourth embodiment, the beverage preparation apparatus further includes a position detection unit and an alarm notification unit. The position detection unit is used to detect the actual position of the dispensing device, and the alarm notification unit is used to notify the user of an operational abnormality. The dispensing device has a maximum downward displacement distance.

[0088] Step S601, which controls the movement of the liquid dispenser based on the first pressure value and the maximum pressure value, includes: S6020: When the liquid outlet moves down the maximum distance and the first pressure value is still 0, control the liquid outlet to stop moving down and control the alarm prompt unit to issue an alarm prompt.

[0089] In some usage scenarios, when a user places a container on the receiving platform, the container may be completely off-center from the dispensing nozzle. In this case, the dispensing nozzle may continue to move downwards without contacting the container. If the dispensing nozzle moves downwards without restriction, it is highly likely that the dispensing nozzle will continue to move downwards until it touches the bottom of the equipment, which may cause the dispensing nozzle drive mechanism to be damaged due to stalling and overload, or the dispensing pipe itself to be deformed or broken due to hard impact.

[0090] By setting a maximum movement distance, when the dispenser moves down the maximum distance but the first pressure value remains 0, it indicates an abnormality with the container placed on the receiving platform. This stops the dispenser from moving downwards and triggers an alarm. This limits the dispenser's movement, preventing structural wear or breakage caused by excessive movement and extending the equipment's lifespan. Simultaneously, the alarm alert helps users quickly identify the abnormality and facilitates timely problem resolution.

[0091] It should be noted that there is no obvious sequential relationship between step S6020 and steps S6010~S6019, and step S6020 can be carried out throughout the entire process of the liquid outlet moving downward.

[0092] As mentioned above, before adjusting the dispensing device, the container's weight is obtained. This invention does not impose specific restrictions on the method of obtaining the container's weight. In some application scenarios, such as commercial beverage preparation equipment, the container specifications are relatively uniform, and containers of the same specification have the same weight. Users can pre-input the weights corresponding to different container specifications based on all available specifications, and then simply call the corresponding weight parameter during beverage preparation.

[0093] In other application scenarios, such as home beverage preparation equipment, the containers come in various sizes. In such cases, a weighing device can be used to detect the weight of the empty cup of the container, thereby obtaining the container's own weight.

[0094] In one embodiment, please refer to Figure 5 , Figure 5 This is a flowchart of a fifth embodiment of a method for adjusting the dispensing device of a beverage preparation apparatus provided by the present invention. In the fifth embodiment, step S10, which involves obtaining the weight of the container, includes: S101: The weight of the empty cup of the container on the receiving platform is detected by the weighing unit and taken as the weight of the container itself.

[0095] Specifically, the beverage preparation equipment also has an alarm notification unit, which is used to alert the user to any abnormalities in the current operation.

[0096] After step S10 of obtaining the container's own weight and before step S30 of controlling the dispensing device to move downward from its initial position, the following steps are also included: S20: When the weight of the empty cup meets the preset weight range, control the liquid dispenser to start moving downward; S30: When the weight of the empty cup exceeds the preset weight range, control the liquid dispenser to shut off and control the alarm prompt unit to issue an alarm prompt.

[0097] Understandably, the preset weight range is usually related to the container specifications (capacity, height, material strength) that the device is compatible with. For example, ultralight containers may deform excessively when the dispensing device is pressed against them due to their softness, resulting in distorted pressure detection; overweight containers may not be able to properly contact the rim of the container after the dispensing device moves down because their height exceeds the design range.

[0098] By screening empty cups by weight, it is ensured that only containers that meet the design expectations enter the downward movement process, avoiding problems such as failure to adjust the position of the liquid outlet tube (e.g., inability to accurately tighten, or disordered pressure signals) and deviations in liquid volume calculation (e.g., abnormal empty cup weight causing liquid volume calculation failure) caused by mismatch in container physical characteristics, thus ensuring the reliability of core functions.

[0099] Please see Figure 6 and Figure 7 The present invention also provides a method for adjusting the dispensing device of a beverage preparation apparatus. Continuing above, the beverage preparation apparatus includes a dispensing device and a weighing unit, the weighing unit being used to hold a container collecting the solution discharged from the dispensing device. The dispensing device, the container, and the weighing unit are arranged in the same vertical direction.

[0100] Please see Figure 6 , Figure 6 A flowchart of the sixth embodiment of a liquid dispensing device adjustment method for a beverage preparation apparatus provided by the present invention. The liquid dispensing device adjustment method includes: S10': Control the liquid outlet to be in the initial liquid outlet position; S20': Obtain the real-time pressure detected by the weighing unit; S30': When the first real-time pressure detected by the weighing unit is equal to the self-weight T1 of the container, the liquid outlet is controlled to start moving downward; S40': When the liquid outlet contacts the container and the second real-time pressure T2 detected by the weighing unit is greater than T1, control the liquid outlet to move upward to the target liquid outlet position.

[0101] The beverage dispensing device adjustment method provided by this invention first sets an initial dispensing position for the dispensing device, and then controls the dispensing device to be in the initial dispensing position in the initial state. In the initial state, the weighing unit is also in the initial weighing position. It can be understood that the container height is essentially the vertical distance from the bottom to the top of the container, with the bottom of the container resting precisely on the weighing unit, and the top of the container being the position where the dispensing device first contacts the weight after it moves down.

[0102] The weighing unit detects the applied pressure. When an empty container is placed on the weighing unit, the first real-time pressure detected by the weighing unit is equal to the weight T1 of the container. Upon receiving the T1 signal, the dispensing device is controlled to move downward from its initial dispensing position, and the device records the downward movement distance S of the dispensing device in real time.

[0103] The dispensing device continues to move downwards until it just collides with the top of the container. At this point, the slight pressure generated by the collision is transmitted to the weighing unit, causing the signal T2 detected by the weighing unit to be greater than T1. The T2 signal is the trigger point when the dispensing device has contacted the top of the container. The downward movement distance S recorded by the device at this time is the vertical distance from the initial dispensing position of the dispensing device to the top of the container. Since the distance H between the dispensing device at the initial dispensing position and the weighing unit is predetermined in the initial state, the actual height of the container on the weighing unit can be obtained by detecting the downward movement distance S when the dispensing device first contacts the container and calculating the difference between H and S.

[0104] After the T2 signal is triggered, the weighing unit moves upward a preset distance, ensuring that the dispensing device maintains light contact with the top of the container rather than pressing it hard. This prevents the dispensing device from continuously compressing the container, thus avoiding container deformation or affecting subsequent dispensing. However, since the downward movement distance S of the dispensing device when it first contacts the container has already been recorded, the upward movement of the weighing unit does not affect the container height calculation; it is only for optimizing the user experience.

[0105] Simultaneously, based on the detected container height, the dispensing device is controlled to move upwards to the target dispensing position. Thus, pressure changes between the dispensing device and the container are detected using its own weight and second real-time pressure. By using pressure contact as the basis for determining the relative position of the dispensing device and the container, and employing physical contact to sense the position, cumulative errors from indirect height detection are avoided. This allows for precise adjustment of the dispensing device to a position suitable for the container opening, thereby preventing coffee spillage and uneven dispensing.

[0106] Following the above, after triggering the T2 signal, the weighing unit moves upward a preset distance, maintaining a light contact between the dispensing device and the top of the container. In other words, during dispensing, the weighing unit moves upward to the target weighing position, keeping the container in that position to receive the beverage flowing from the dispensing device. After completing one dispensing action and before the next dispensing action, the weighing unit needs to return to the initial weighing position.

[0107] In one embodiment, when the beverage processing equipment is started, or when the weighing unit does not detect a container placed on it, the weighing unit is controlled to return to its initial weighing position. That is, before each dispensing, the weighing unit needs to return to its initial weighing position to ensure the accuracy of the container height measurement, thereby ensuring the accuracy of the dispensing device position adjustment.

[0108] It should be noted that the present invention does not impose specific restrictions on the initial position of liquid dispensing. The initial position of liquid dispensing can be the highest position on the moving stroke of the liquid dispenser; the initial position of liquid dispensing can also be the middle position on the moving stroke of the liquid dispenser.

[0109] The target liquid outlet position can be lower than or higher than the initial liquid outlet position. Furthermore, the target liquid outlet position can be a fixed position or a real-time position calculated based on the actual height of the container on the weighing unit. The calculation of the target liquid outlet position based on the actual height of the container has already been explained in detail above and will not be repeated here.

[0110] In one embodiment, the dispensing device has a highest position in the vertical direction, and the initial dispensing position is located below the highest position. That is, the initial dispensing position is located at the middle position of the dispensing device's travel distance.

[0111] In some applications, the container is a regular cup, and when the cup is placed on the weighing unit, the rim of the cup is much lower than the dispensing device. When the first real-time pressure detected by the weighing unit equals the weight T1 of the container, the dispensing device can be directly controlled to move downwards.

[0112] In other application scenarios, the container is a very tall cup. When the cup is placed on the weighing unit, the rim of the cup is higher than the dispensing device. When the first real-time pressure detected by the weighing unit equals the weight T1 of the container, the dispensing device is controlled to move upward from the initial dispensing position to the highest position. At this point, the dispensing device is higher than the rim of the cup. Then, the dispensing device is controlled to move downward, thereby ensuring accurate measurement of the cup's height.

[0113] Continuing from the above, by controlling the dispensing device to move upwards to the target dispensing position, dispensing can begin. In one embodiment, please refer to... Figure 7 , Figure 7 A flowchart of the seventh embodiment of a liquid dispensing device adjustment method for a beverage preparation apparatus provided by the present invention. After step S40' of controlling the liquid dispensing device to move upward to the target liquid dispensing position, the method includes: S50': Control the liquid dispenser to dispense liquid and inject beverage into the container; S60': When the weighing unit detects a third real-time pressure T3, and the third real-time pressure T3 is equal to the sum of the container's own weight T1 and the preset beverage weight, the dispensing device is controlled to stop dispensing liquid. S70': Control the liquid outlet to move to the initial liquid outlet position.

[0114] In this embodiment, a preset dispensing weight is set according to the type of beverage selected by the user. After the dispensing device dispenses liquid, the beverage flowing from the dispensing device is injected into the container. The weighing unit detects a third real-time pressure T3. When the third real-time pressure T3 equals the sum of the container's own weight T1 and the preset beverage weight, it indicates that the beverage flowing from the dispensing device has reached the preset dispensing weight, and at this time, the dispensing device is controlled to stop dispensing. After completing this dispensing action, the dispensing device is controlled to move back to the initial dispensing position to prepare for the next dispensing adjustment action.

[0115] Specifically, step S70', which controls the liquid dispenser to move to the initial liquid dispensing position, includes: S701': Compare the target liquid outlet position with the initial liquid outlet position; S702': When the target liquid outlet position is lower than the initial liquid outlet position, control the liquid outlet to move upward to the initial liquid outlet position; S703': When the target liquid outlet position is higher than the initial liquid outlet position, the third real-time pressure detected by the weighing unit is obtained; S704': Based on the third real-time pressure and when it is determined that the user has taken the container from the weighing unit, control the liquid dispenser to move downward to the initial liquid dispensing position.

[0116] As mentioned above, when the third real-time pressure T3 is equal to the sum of the container's own weight T1 and the preset beverage weight, it means that the beverage flowing out of the dispensing device has reached the preset dispensing weight. At this time, the dispensing device is controlled to stop dispensing and needs to be moved back to the initial dispensing position.

[0117] Since the dispensing device is at the target dispensing position during dispensing, it is necessary to compare the target dispensing position with the initial dispensing position before controlling the dispensing device to reset. When the target dispensing position is lower than the initial dispensing position, the dispensing device can be directly controlled to move upward to the initial dispensing position. When the target dispensing position is higher than the initial dispensing position, the dispensing device needs to be controlled to move downward to the initial dispensing position when it is determined that the user has removed the container from the weighing unit, thereby avoiding interference from the container in the resetting of the dispensing device.

[0118] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
