[0059] The present application further provides a control method for a beverage output device, which can be used for any of the above beverage output devices, such as Figure 3 shown Figure 3 is a schematic flowchart of an embodiment of the control method for the beverage output device of the present application. The control method of this embodiment specifically includes the following steps:

[0060] Step S31: respectively obtain the first radius of the cup mouth of the water receiving container located in the water receiving area and the second radius of the cup bottom of the water receiving container.

[0061] The control mechanism respectively obtains the first radius of the cup mouth of the water receiving container located in the water receiving area and the second radius of the cup bottom of the water receiving container.

[0062] Optionally, in this embodiment, the image information of the water receiving container placed in the water receiving area can be obtained through an image sensor arranged above the water receiving area. The image sensor feeds the image information back to the control mechanism, and the control mechanism identifies the cup mouth image of the water receiving container from the image information, and further obtains the first radius of the cup mouth based on the cup mouth image.

[0063] In an application scenario, only one image sensor is arranged on the base of the beverage output device, and the first radius determined by the control mechanism based on the image information obtained by the image sensor is the first radius of the cup mouth of the water receiving container.

[0064] In another application scenario, multiple different image sensors can be arranged at multiple different positions on the base of the beverage output device. The control mechanism fuses and processes the image information obtained by the multiple image sensors to obtain the image information of the water receiving container, and obtains the first radius of the cup mouth of the water receiving container based on the image information; or the control mechanism obtains the corresponding first radius for each cup based on each image information, and then combines the position information of the multiple image sensors and the corresponding first radius to obtain the first radius of the cup mouth of the water receiving container.

[0065] The image sensor periodically obtains the image information of the water receiving container after the beverage output device is powered on. After the control mechanism determines that there is a water receiving container placed in the water receiving area, it can obtain the image information of the water receiving container after beverage output from the image information fed back by the image sensor; or after the control mechanism determines that there is a water receiving container placed in the water receiving area, it controls the image sensor to obtain the image information of the water receiving container; or the control mechanism controls the image sensor to obtain the image information of the water receiving container in response to the user's beverage output operation or beverage output instruction, and so on.

[0066] Optionally, in this embodiment, an infrared array sensor or the like provided on the water receiving area may be used to obtain the occlusion area of the water receiving container placed on the water receiving area on the water receiving area, and the control mechanism obtains the second radius of the bottom of the water receiving container based on this occlusion area.

[0067] Optionally, the first radius is the inner diameter of the cup mouth, and the second radius is the inner diameter of the cup bottom to improve the control accuracy; or the first radius is the outer diameter of the cup mouth, and the second radius is the outer diameter of the cup bottom to improve the data processing efficiency of the control mechanism.

[0068] Step S32: In response to the beverage output device outputting a beverage, obtain the liquid level information in the water receiving container.

[0069] The control mechanism controls the beverage output mechanism to output a beverage in response to a user's beverage output operation or a beverage output instruction or the like, and periodically obtains the liquid level information in the water receiving container after the beverage output mechanism outputs the beverage.

[0070] Optionally, after the control mechanism controls the beverage output mechanism to output a beverage, it may control an image sensor to obtain the image information of the water receiving container, and obtain the liquid level information in the water receiving container based on this image information; or the image sensor periodically obtains the image information of the water receiving container after the beverage output device is powered on, and the control mechanism obtains the liquid level information in the water receiving container after the beverage is output from the image information fed back by the image sensor after the beverage output mechanism outputs the beverage; or the control mechanism controls the image sensor to obtain the image information of the water receiving container in response to a user's beverage output operation or a beverage output instruction, and obtains the liquid level information in the water receiving container based on this image information, and so on.

[0071] Step S33: Determine whether the current beverage output meets the stop output condition based on the first radius, the second radius, and the liquid level information.

[0072] The control mechanism determines whether the current beverage output meets the stop output condition based on the first radius, the second radius, and the liquid level information.

[0073] Optionally, the liquid level information in this embodiment includes the liquid level radius, and this embodiment may implement step S33 through the method shown in Figure 4 The method of this embodiment includes steps S41 to S43.

[0074] Step S41: Compare the first radius with the second radius.

[0075] Step S42: In response to the first radius being greater than the second radius, obtain the first ratio between the liquid level radius and the first radius.

[0076] Step S43: In response to the first ratio being greater than the first preset ratio, it is determined that the current beverage output meets the stop output condition; wherein, the first preset ratio is less than 1 and greater than 0.7.

[0077] Steps S41 to S43 are introduced together: The control mechanism compares the first radius of the cup mouth of the water receiving container with the second radius of the cup bottom. If the first radius of the cup mouth of the water receiving container is greater than the second radius of the cup bottom, that is, the water receiving container is a container with a larger upper part and a smaller lower part, the control mechanism obtains the liquid surface radius, that is, the first ratio between the current liquid surface radius and the first radius of the cup mouth; if the first ratio is greater than the first preset ratio, the control mechanism determines that the current beverage output meets the stop output condition; wherein, the first preset ratio is less than 1 and greater than 0.7. Otherwise, it is determined that the current beverage output does not meet the stop output condition.

[0078] Among them, the first preset ratio can specifically be 0.9, 0.85, 0.8, 0.75, etc.

[0079] In other embodiments, the first preset ratio can be adjusted based on usage requirements.

[0080] In this embodiment, for a water receiving container with a large cup mouth and a small cup bottom, the ratio between the liquid surface radius in the water receiving container and the first radius of the cup mouth is used to determine the height of the solution in the water receiving container, which can improve the accuracy of determining the stop of beverage output; further, when the ratio between the liquid surface radius and the first radius of the cup mouth is greater than the first preset ratio, it can be determined that the liquid surface is close to the end face of the cup mouth, so as to determine that the current beverage output of the beverage output device meets the stop output condition, which can improve the problem of beverage overflow and premature stop of beverage output due to insufficient beverage volume in the water receiving container.

[0081] In one embodiment, the liquid surface information includes the liquid surface radius, and step S33 can also be implemented by the method as Figure 5 shown. The method of this embodiment includes steps S51 to S53.

[0082] Step S51: Compare the first radius with the second radius.

[0083] Step S52: In response to the first radius being less than the second radius, obtain the second ratio between the liquid surface radius and the second radius.

[0084] Step S53: In response to the second ratio being less than the second preset ratio, it is determined that the current beverage output meets the stop output condition; wherein, the second preset ratio is greater than 0 and less than 0.3.

[0085] Steps S51 to S53 will be introduced together: The control mechanism compares the first radius of the cup mouth of the water receiving container with the second radius of the cup bottom; if the first radius of the cup mouth of the water receiving container is smaller than the second radius of the cup bottom, that is, the water receiving container is a container with a smaller upper part and a larger lower part, the control mechanism obtains the liquid surface radius, that is, the second ratio between the current liquid surface radius and the second radius of the cup bottom; if the second ratio is smaller than the second preset ratio, the control mechanism determines that the current beverage output meets the stop output condition; wherein, the second preset ratio is greater than 0 and less than 0.3. If not, it is determined that the current beverage output does not meet the stop output condition.

[0086] Among them, the second preset ratio can specifically be 0.25, 0.2, 0.15, 0.1, etc.

[0087] In other embodiments, the second preset ratio can be adjusted based on usage requirements.

[0088] In this embodiment, for a water receiving container with a small cup mouth and a large cup bottom, the ratio between the liquid surface radius in the water receiving container and the second radius of the cup bottom is used to determine the height of the beverage in the water receiving container, which can improve the accuracy of determining the stop of beverage output; further, when the ratio between the liquid surface radius and the second radius of the cup bottom is smaller than the second preset ratio, it can be determined that the liquid surface is close to the end face of the cup mouth, so as to determine that the current beverage output of the beverage output device meets the stop output condition, which can improve the problem of beverage overflow and premature stop of beverage output due to insufficient beverage volume in the water receiving container.

[0089] In one embodiment, the liquid surface information in this embodiment includes the liquid surface radius, and this embodiment can implement step S33 through the method shown in Figure 6 The method of this embodiment includes steps S61 to S64.

[0090] Step S61: Compare the first radius with the second radius.

[0091] For specific implementation manners, reference can be made to the above embodiments.

[0092] Step S62: In response to the first radius being equal to the second radius, obtain the first volume of the beverage output by the beverage output device.

[0093] If the first radius of the cup mouth is equal to the second radius of the cup bottom, the control mechanism further obtains the first volume of the beverage output by the beverage output device.

[0094] Specifically, the control mechanism obtains the flow rate, radius and beverage output duration of the beverage output port of the beverage output mechanism, and the control mechanism calculates the product of the flow rate, radius and beverage output duration as the first volume of the beverage output by the beverage output device.

[0095] Among them, the flow rate, radius, etc. of the beverage outlet can be pre-stored in the control mechanism. Or the flow rate of the beverage outlet can be obtained in real time through a flow meter.

[0096] Step S63: Obtain the second volume of the water receiving container based on the liquid level information.

[0097] Optionally, the control mechanism can obtain the liquid level area change rate based on the liquid level information and obtain the flow rate of the beverage in the water receiving container; obtain the height of the water receiving container based on the liquid level area change rate and the flow rate; determine the second volume of the water receiving container based on the first radius, the second radius, and the height.

[0098] In an application scenario, the control mechanism can obtain the liquid level area based on the liquid level image, and can obtain the liquid level area change rate based on the liquid level area corresponding to the previous moment, the liquid level area corresponding to the current moment, and the time duration between the previous moment and the current moment; the control mechanism obtains the flow rate of the beverage outlet based on the flow rate and radius of the beverage outlet, and can obtain the flow rate of the beverage in the water receiving container based on the flow rate of the beverage outlet and the liquid level radius; the control mechanism obtains the height of the water receiving container based on the liquid level area change rate and the flow rate, and determines the second volume of the water receiving container based on the first radius, the second radius, and the height.

[0099] Step S64: Determine whether the current beverage output meets the stop output condition based on the first volume and the second volume.

[0100] In this embodiment, when the radius of the cup mouth is the same as the radius of the cup bottom, it is determined whether the current beverage output of the beverage output mechanism meets the stop output condition by outputting the beverage volume, that is, the first volume and the volume of the water receiving container, that is, the second volume. Since the volume relationship is the most direct and accurate way to determine whether the beverage overflows, this embodiment can improve the accuracy of determining the stop of beverage output.

[0101] Optionally, this embodiment can implement step S63 through the method as Figure 7 shown. The method of this embodiment includes step S71 and step S72.

[0102] Step S71: Calculate the third ratio between the first volume and the second volume.

[0103] Step S72: In response to the third ratio being less than the third preset ratio, determine that the current beverage output meets the stop output condition; where the third preset ratio is less than 1 and greater than 0.7.

[0104] Steps S71 and S72 are introduced together: The control mechanism calculates and outputs the volume of the drink, that is, the third ratio between the first volume and the volume of the water-receiving container, that is, the second volume. If the third ratio is less than the third preset ratio, the control mechanism determines that the current drink output meets the stop output condition. If not, it is determined that the current drink output does not meet the stop output condition.

[0105] Among them, the third preset ratio can specifically be 0.9, 0.85, 0.8, 0.75, etc.

[0106] In other embodiments, the third preset ratio can be adjusted based on usage requirements.

[0107] In another embodiment, regardless of the size between the first radius of the cup mouth and the second radius of the cup bottom, the ratio between the liquid surface radius and the first radius of the cup mouth can be directly obtained to determine whether the current drink output of the drink output device meets the stop output condition based on this ratio and the preset ratio.

[0108] For example, for a water-receiving container with a large cup mouth and a small cup bottom, if the ratio between the liquid surface radius and the first radius of the cup mouth is greater than the third preset ratio, it is determined that the current drink output of the drink output device meets the stop output condition; for a water-receiving container with a small cup mouth and a large cup bottom, if the ratio between the liquid surface radius and the first radius of the cup mouth is greater than the fourth preset ratio, it is determined that the current drink output of the drink output device meets the stop output condition; among them, the third preset ratio is greater than the fourth preset ratio.

[0109] In other embodiments, the corresponding difference can be used instead of the above ratio.

[0110] In another embodiment, step S33 can be implemented by the method as Figure 8 shown. The method of this embodiment includes steps S81 to S83.

[0111] Step S81: Obtain the first volume of the drink output by the drink output device.

[0112] Specifically, the control mechanism obtains the flow rate, radius, and output drink duration of the drink output port of the drink output mechanism, and the control mechanism calculates the product of the flow rate, radius, and output drink duration as the first volume of the drink output by the drink output device.

[0113] Step S82: Determine the second volume of the water-receiving container based on the first radius, second radius, and liquid surface information.

[0114] The control mechanism can obtain the liquid surface area change rate based on the liquid surface information and obtain the flow rate of the liquid in the water-receiving container; obtain the height of the water-receiving container based on the liquid surface area change rate and the flow rate; determine the second volume of the water-receiving container based on the first radius, second radius, and height.

[0115] The control mechanism can also directly determine the height of the water receiving container based on the first volume, the first radius, and the second radius.

[0116] For specific implementation details, refer to step S63.

[0117] Step S83: Determine whether the current beverage output meets the stop output condition based on the first volume and the second volume.

[0118] For specific implementation details, refer to step S64.

[0119] In this embodiment, by using the output beverage volume, i.e., the first volume, and the volume of the water receiving container, i.e., the second volume, to determine whether the current beverage output of the beverage output mechanism meets the stop output condition. Since the volume relationship is the most direct and accurate way to determine whether the beverage overflows, this embodiment can improve the accuracy of determining the stop of beverage output.

[0120] In another embodiment, as Figure 1 shown, the control mechanism can also directly determine the beverage height based on the first volume, the first radius, and the second radius. The first volume V = (1 / 3)*π*h*(R’2 + R2

[0121] + R’*R2), where R’ is the liquid surface radius, R2 is the second radius, and h is the beverage height. The control mechanism obtains the ratio between the height of the output beverage volume and the height of the obtained water receiving container to determine whether the stop output condition is met. For example, when the height of the beverage in the water receiving container is 9 / 10 from the top, i.e., the ratio is 9 / 10, it is determined that the stop output condition is met.

[0122] Step S34: In response to the current beverage output meeting the stop output condition, control the beverage output device to stop outputting beverages.

[0123] If the current beverage output of the beverage output device meets the stop output condition, the control mechanism controls the beverage output mechanism to stop outputting beverages.

[0124] If the current beverage output of the beverage output device does not meet the stop output condition, the beverage output mechanism continues to output beverages, and the control mechanism continues the above detections and determinations.

[0125] This embodiment can determine whether the current beverage output of the beverage output device meets the stop output condition based on the radius information of the cup mouth and the cup bottom of the water receiving container and the liquid level information in the water receiving container when the beverage output device outputs the beverage. This enables the determination of water cut-off in this embodiment to consider factors such as the radius of the cup mouth and the cup bottom of the water receiving container, and further enables the determination of stopping beverage output in this embodiment to adapt to a variety of water receiving containers with different sizes and shapes. On the one hand, the control method of this embodiment can be applied to a variety of water receiving containers with different sizes and shapes, which can improve the intelligence and accuracy of the beverage output control of the beverage output device; on the other hand, it can reduce the influence of interference objects on the existing method of determining the stop of beverage output based on ultrasonic waves. Therefore, it can further improve the intelligence and accuracy of the beverage output control of the beverage output device.

[0126] In one embodiment, in the scenario where the beverage output device outputs water, as Figure 9 shown, the control mechanism detects that there is a water receiving container, such as a water cup, entering the drinking area, such as the water receiving area, based on the image information obtained by the image sensor, such as a camera, and controls the beverage output mechanism to start outputting the beverage; at the same time, the control mechanism obtains the image information of the water cup through the camera to obtain the radius of the upper diameter of the water cup, that is, the first radius R1 of the cup mouth described above, and obtains the radius of the bottom of the cup by detecting the bottom cup area through the sensor on the water receiving area, that is, the second radius R2 of the cup bottom described above; the control mechanism continuously detects the liquid level radius R' based on the image information of the camera and determines whether the liquid level radius R' meets the preset stop output condition; if so, the control mechanism controls the beverage output mechanism to stop outputting the beverage. If not, the control mechanism continues the above detection and judgment. The method for the control mechanism to determine the stop of beverage output can refer to the above embodiment.

[0127] In one embodiment, the camera continuously detects the interference objects in the water dispenser area and the entry and exit of the water receiving container. When the control mechanism detects that there is a water receiving container entering the water receiving area through the camera, it obtains the image information of the water cup through the camera and obtains the first radius R1 of the cup mouth based on the image information.

[0128] In one embodiment, the stop output condition can also be adjusted according to the actual usage scenario and test situation. The user can set the stop output condition through the APP or the screen. For example, the user can set the beverage flow rate to increase or decrease through the APP, and set the stop output condition when the volume of the beverage in the cup reaches 80%. The above conditions are freely set by the user, and the cloud calculates and judges based on the set beverage flow rate, the known radius of the beverage output port, and the values detected by the camera and the bottom sensor.

[0129] Furthermore, abnormal situations where no drink is dispensed can be determined based on the image information obtained by the camera. For example, if the object placed is an interfering object such as a hand, a covered cup, a mobile phone, a cardboard box, etc., the control mechanism will determine that no drink is dispensed, which is an advantage over ultrasonic sensors.

[0130] Meanwhile, during the process of dispensing a drink, when the camera detects an interfering object placed at the mouth of the water cup or the water cup leaves the drinking area, the water supply will automatically stop, which is safer.
