[0002] Water dispensers are a common household appliance. As living standards continue to improve, water dispensers are becoming increasingly popular, and users have higher and higher requirements for their functions. In addition to providing hot water, water dispensers also need to ensure the safety of users during use.

[0003] Currently, most water dispenser switches use a structure where a spindle with a return spring is hinged to the control handle. By pressing down or lifting the handle, the spindle valve is moved to control the opening and closing of the water dispensing valve. This type of water dispenser switch has a simple principle and is easy to operate.

[0004] However, there is a risk of being scalded by hot water in many situations, such as when the user accidentally touches the handle or when the water outlet is not aligned with the water container. Summary of the Invention

[0024] Optionally, if the detected object exists within the target range, determining whether the detected object contains the target container includes:

[0025] Determine the number of objects to be detected;

[0026] If the number of detected objects is greater than the preset number, the operation of controlling the water dispenser to turn on the water dispensing function will not be executed;

[0027] If the number of objects being detected is equal to the preset number, determine whether the objects being detected contain the target container.

[0028] Optionally, when the target container is included in the object being detected, determining the offset of the target container relative to the water dispenser's outlet includes:

[0029] If the object being detected contains a target container, determine the number of times the target container shakes within a preset time period;

[0030] If the number of shaking events is less than or equal to a third threshold, the offset of the target container relative to the water outlet of the water dispenser is determined.

[0031] Optionally, after controlling the water dispenser to turn on the water dispensing function when the offset is less than or equal to the first threshold, the method further includes:

[0032] Determine the second plane where the opening of the target container is located;

If it is determined that there is a detected object within the target range and the detected object includes the target container, the system further determines the offset between the target container and the water dispenser's outlet. If the offset is less than a first threshold, the system then controls the water dispenser to start the water dispensing function.

[0054] Method Implementation Examples

[0055] The water dispenser control method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0056] Reference Figure 1 The diagram illustrates a flowchart of a water dispenser control method according to an embodiment of this application. Figure 1 As shown, the method specifically includes steps S101 and S105:

[0057] Step S101: Upon receiving a water dispensing command, acquire the target image within the target range corresponding to the water dispenser.

[0058] In this embodiment, the water dispenser may include a detection component, a control component, and a water dispensing command acquisition component. Both the detection component and the water dispensing command acquisition component are communicatively connected to the control component. The water dispensing command acquisition component may include at least one of a function button and a voice recognition unit. The control component may receive a user-inputted water dispensing command using the function button or the voice recognition unit, and acquire a target image within the target range corresponding to the water dispenser through the detection component.

[0059] The detection component may include an image acquisition unit, which may be a camera, scanner or other functional unit with image acquisition capabilities; the control component may be any component with data processing and control capabilities.

[0060] It should be noted that the water dispensing command can be for different water temperatures. For example, the water dispensing command can be for room temperature water (around 20°C), for warm water (30°C to 40°C), or for hot water (70°C to 100°C).

[0061] As an example, a water dispenser may include at least two water outlets, each corresponding to a different water temperature. Specifically, room temperature water corresponds to the first water outlet, and hot water corresponds to the second water outlet. The water dispensing command acquisition component includes a first function button corresponding to the first water outlet and a second function button corresponding to the second water outlet. The control component can acquire the room temperature water dispensing command through the first function button and the hot water dispensing command through the second function button. Alternatively, the water dispensing command acquisition component may also include a voice recognition unit. The user can directly input the room temperature water dispensing command or the hot water dispensing command to the control component of the water dispenser through the voice recognition unit. When the control component receives the room temperature water dispensing command or the hot water dispensing command through the voice recognition unit, it can, in step S105, control the first water outlet of the water dispenser to dispense room temperature water based on the room temperature water dispensing command, or control the second water outlet of the water dispenser to dispense hot water based on the hot water dispensing command, provided that the offset is less than or equal to a first threshold.

[0062] As an example, the water dispenser may include only one water outlet. The function buttons in the water dispensing command acquisition component include a water temperature control area and a water dispensing control area. The control component can obtain the water temperature input by the user through the water temperature control area and obtain the water dispensing command corresponding to the water temperature input by the user through the water dispensing control area. Based on the water temperature and the water dispensing command corresponding to the water temperature, the water dispensing command in step S101 is obtained. In step S105, if the offset is less than or equal to the first threshold, the water dispenser is controlled to start the water dispensing function according to the water dispensing command. At this time, the water temperature of the water dispenser is equal to the water temperature input by the user. Of course, the water dispensing command acquisition component may also include a voice recognition unit. Users can directly input a normal temperature water dispensing command or a hot water dispensing command to the control component of the water dispenser through the voice recognition unit. When the control component receives a normal temperature water dispensing command or a hot water dispensing command through the voice recognition unit, it can control the water dispenser to dispense normal temperature water based on the normal temperature water dispensing command or hot water based on the hot water dispensing command, provided that the offset is less than or equal to the first threshold in step S105.

[0063] The target area can be below the water outlet of the water dispenser, and includes the area of ​​the water outlet. In this embodiment, to avoid accidental water discharge from the water outlet, the image acquisition unit can be placed near the water outlet of the water dispenser, and the image within the target area near the water outlet acquired by the image acquisition unit is the target image.

[0064] It should be noted that the target image is a real-time image within the target range acquired by the image acquisition unit after the control component receives the water dispensing command. Specifically, after receiving the water dispensing command and before controlling the water dispenser to turn off the water dispensing function, the control component can continuously acquire the target image within the target range according to a preset cycle, and perform the operations corresponding to steps S102 to S105 based on the target image.

[0065] As an example, refer to Figure 2 This illustration shows a schematic diagram of the image acquisition unit's location according to an embodiment of this application. The water dispenser 10 includes a first water outlet 12-1 and a second water outlet 12-2. The image acquisition unit 11 in the water dispensing command acquisition component is located between the first water outlet 12-1 and the second water outlet 12-2, and is used to acquire a target image within a target range corresponding to the water dispenser. The target range includes a first range corresponding to the first water outlet 12-1 and a second range corresponding to the second water outlet 12-2.

[0066] Step S102: Based on the target image, determine whether there is a detected object within the target range.

[0067] The object to be detected can be any object other than the background that the image acquisition unit can acquire. The background includes, but is not limited to, the water dispenser itself, the tabletop, and the ground. Specifically, if there are no other objects in the target image besides the background, the control component can determine that there is no object to be detected in the target area; if there are other objects in the target image besides the background, the control component can determine that there is an object to be detected in the target area.

[0068] Before step S102, an image database can be established in advance. This image database may include, but is not limited to, background images, target container images, human body part images (e.g., an adult's hand, an adult's arm, a child's hand, a child's arm, etc.), and various pet images that can be acquired by the image acquisition unit.

[0069] In the process of determining whether a detected object exists within the target area based on the target image, the control component can match each object in the target image with images in the image database. If an object in the target image only matches a background image in the image database, it can be determined that no detected object exists within the target area. If an object in the target image matches an image other than a background image in the image database, it can be determined that a detected object exists within the target area.

[0070] In this embodiment of the application, if the control component determines that there is a detected object within the target range, it executes step S103; if it determines that there is no detected object within the target range, it does not execute the operation of controlling the water dispenser to turn on the water dispensing function.

[0071] Step S103: If the object to be detected exists within the target range, determine whether the object to be detected contains the target container.

[0072] Specifically, if the detection object is determined to exist within the target range through step S102, the control component can further match each object in the detection object with the image in the image database in turn; if any object in the detection object matches the target container image in the image database, the control component can determine that the detection object contains the target container; if none of the objects in the detection object match the target container image in the image database, the control component can determine that the detection object does not contain the target container.

[0073] The target container can be any water container, such as a water cup, kettle, or water bottle.

[0074] In this embodiment, if the control component determines that the detected object contains the target container, it executes step S104; if it determines that the detected object does not contain the target container, it does not execute the operation of controlling the water dispenser to start dispensing water. For example, in scenarios where a child touches the water function button out of curiosity, a pet accidentally touches the function button, or the voice recognition unit misinterprets the water dispensing command, if the control component determines in step S103 that the detected object does not contain the target container, it will not execute the operation of controlling the water dispenser to start dispensing water. This can effectively avoid the risk of children or pets being scalded, and can also avoid problems such as water waste caused by the water dispenser accidentally dispensing water.

[0075] Step S104: If the target container is included in the object being detected, determine the offset of the target container relative to the water outlet of the water dispenser.

[0076] In this embodiment of the application, when the object being detected includes a target container, the control component can further determine the offset of the target container relative to the water outlet of the water dispenser, and continue to execute step S105 based on the offset.

[0077] Specifically, the first position of the image acquisition unit in the water dispenser, the second position of the water outlet, and the first positional relationship between the image acquisition unit and the water outlet can be predetermined. When the control component determines the target container within the target range from the target image, it can further determine the second positional relationship between the container opening of the target container and the first position based on the first position of the image acquisition unit. With the first position fixed, the control component can further calculate the third positional relationship between the container opening of the target container and the water outlet based on the first and second positional relationships. If the third positional relationship indicates that the container opening of the target container is directly below the first water outlet, the control component can determine that the offset of the target container relative to the water outlet of the water dispenser is 0. If the third positional relationship indicates that the container opening of the target container is not directly below the first water outlet, the control component can determine that the offset of the target container relative to the water outlet of the water dispenser is 1. Here, 0 indicates that the container opening of the target container and the water outlet are aligned; 1 indicates that the container opening of the target container and the water outlet are not aligned.

[0078] Step S105: If the offset is less than or equal to the first threshold, control the water dispenser to turn on the water dispensing function.

[0079] In this embodiment, the first threshold can be set to 0, or any value between 0 and 1. If the offset of the target container relative to the water outlet of the water dispenser is 0, it indicates that the container opening and the water outlet of the target container are aligned, and the control component controls the water dispenser to turn on the water dispensing function based on the water dispensing command received in step S101; if the offset of the target container relative to the water outlet of the water dispenser is 1, it indicates that the container opening and the water outlet of the target container are not aligned, and the control component does not perform the operation of controlling the water dispenser to turn on the water dispensing function, so as to avoid the problem of scalding or water waste caused by turning on the water dispensing function when the container opening and the water outlet are not aligned.

[0080] In addition, the water dispenser may also include a voice prompt component. If, in step S103, it is determined that the target container is not included among the detected objects, the control component, while not performing the operation of controlling the water dispenser to start dispensing water, can also prompt the user via the voice prompt component to remove the detected object within the target range. If, in step S105, it is determined that the offset is greater than a first threshold, the control component, while not performing the operation of controlling the water dispenser to start dispensing water, can also prompt the user via the voice prompt component to align the target container with the water outlet.

[0081] In related technologies, most water dispenser switches use a structure where a spindle with a return spring is directly hinged to the control handle. By pressing down or lifting the handle, the core valve moves to control the opening and closing of the water valve. However, if the user accidentally touches the handle, the water dispenser will dispense water directly, which can easily cause injury. For example, if a child touches the switch out of curiosity, or a pet accidentally touches the switch, or if the user's container opening is not aligned with the water dispenser's outlet, the dispenser will directly control the water dispenser to dispense water based on the received water dispensing command, posing a risk of scalding the user and also causing unnecessary waste of water resources. In this embodiment, after receiving a water dispensing command, before controlling the water dispenser to start the water dispensing function, the system first determines the offset between the target container and the water dispenser's outlet based on the target image within the target range corresponding to the water dispenser. If it is determined that there is a detected object within the target range and the detected object includes the target container, the system further determines the offset between the target container and the water dispenser's outlet. If the offset is less than a first threshold, the system then controls the water dispenser to start the water dispensing function. This avoids the problem of users being scalded by hot water due to accidentally touching the water dispenser's water dispensing switch or due to various reasons causing the water outlet to be misaligned with the target container when dispensing water. This realizes the intelligent control method of the water dispenser, which not only avoids unnecessary water waste but also improves the safety of users when using the water dispenser.

[0082] Reference Figure 3 The flowchart illustrates another water dispenser control method provided in an embodiment of this application, as shown below. Figure 3 As shown, the method specifically includes steps S201 and S219:

[0083] Step S201: Upon receiving a water dispensing command, acquire the target image within the target range corresponding to the water dispenser.

[0084] This step can be referred to in the detailed description of step S101, and will not be repeated here.

[0085] Step S202: Based on the target image, determine whether there is a detected object within the target range.

[0086] This step can be referred to in the detailed description of step S102, and will not be repeated here.

[0087] If the control component determines that there is a target object within the target range, it executes step S204; if it determines that there is no target object within the target range, it executes step S203.

[0088] Step S203: Do not perform the operation of controlling the water dispenser to turn on the water dispensing function.

[0089] Specifically, if the control component determines in step S202 that there is no object to be detected within the target range, it will not execute the operation of controlling the water dispenser to start the water dispensing function based on the received water dispensing command, so as to avoid the water dispenser dispensing water when there is no object to be detected within the target range, thus avoiding waste of water resources.

[0090] Step S204: Determine the number of objects to be detected.

[0091] Specifically, the control component can determine the number of objects to be detected based on the differences in features such as color and shape among the objects to be detected in the target image.

[0092] Step S205: If the number of detected objects is greater than the preset number, the operation of controlling the water dispenser to turn on the water dispensing function will not be executed.

[0093] Step S206: When the number of detected objects is equal to the preset number, determine whether the detected objects contain the target container.

[0094] In this embodiment of the application, when the control component determines whether the detected object contains the target container when there is a detected object within the target range, it can first determine the number of detected objects based on the target image; then, if the number of detected objects is greater than a preset number, step S205 is executed, and if the number of detected objects is equal to the preset number, step S206 is executed.

[0095] The preset quantities include 1 and 2. Specifically, the case where the number of detected objects is equal to 1 corresponds to a normal user water-collecting scenario, such as a user placing the target container under a water outlet to collect water. Therefore, the control component can match the detected object with the image database to confirm whether the detected object is the target container. If the detected object is the target container, then it is determined that the detected object contains the target container. The case where the number of detected objects is equal to 2 also corresponds to a normal user water-collecting scenario, such as a user holding the target container under a water outlet to collect water. The control component can match each of the 2 detected objects with the image database. If either of the 2 detected objects matches the target container image in the image database, then it is determined that the detected object contains the target container.

[0096] If the control component determines in step S206 that the detected object contains the target container, then it executes step S208; if it determines that the detected object does not contain the target container, then it executes step S207.

[0097] The water dispenser control method provided in this application, when determining that there are detected objects within the target range, first determines the number of detected objects. If the number of detected objects is greater than a preset number, for example, three or more detected objects, it indicates that the situation does not meet the normal water dispensing scenario. In this case, the operation of controlling the water dispenser to start the water dispensing function is not executed, preventing scalding caused by hot water from the water dispenser. This also reduces the operation of the control component matching multiple detected objects with the image database, reducing unnecessary operating overhead of the control component. If the number of detected objects is equal to the preset number, for example, when the user places the target container under the water outlet to dispense water, or when the user holds the target container under the water outlet to dispense water, it indicates that the situation meets the normal water dispensing scenario. The control component can further determine whether the detected objects include the target container. Thus, while ensuring the safety of the user during the use of the water dispenser, unnecessary image database matching operations are reduced, improving the data processing efficiency of the control component in the water dispenser.

[0098] Step S207: Do not perform the operation of controlling the water dispenser to turn on the water dispensing function.

[0099] In this embodiment of the application, when the number of objects to be detected is equal to the preset number, but the target container is not included among the objects to be detected, the control component may not perform the operation of controlling the water dispenser to turn on the water dispensing function, so as to avoid the occurrence of problems such as accidental water dispensing and scalding.

[0100] Step S208: Identify the container opening of the target container and the first center position of the container opening.

[0101] Step S209: Determine the second center position of the water outlet of the water dispenser.

[0102] Step S210: Determine the first offset distance of the first center position relative to the second center position, and determine the first offset distance as the offset of the target container relative to the outlet.

[0103] In this embodiment of the application, the control component can determine the offset of the target container relative to the outlet by determining the first offset distance of the first center position of the container opening of the target container relative to the second center position of the outlet.

[0104] Specifically, the control component can acquire an image of the container opening of the target container from the target image, and determine the first center position of the container opening from the container opening image. The first center position is the location of the center point of the container opening. With the second position of the outlet fixed, the second center position of the outlet's center point can be determined based on the outlet's diameter.

[0105] In determining the first offset distance between the first center position and the second center position, the control component can first project the line connecting the first position and the first center position of the image acquisition unit onto the reference plane to obtain a first projection line segment, and then project the line connecting the first position and the second center position onto the reference plane to obtain a second projection line segment. It is understood that the first projection line segment and the second projection line segment intersect at least one endpoint, and the intersecting endpoint is the first projection point corresponding to the first position. Then, the offset distance between the second projection point other than the first projection point in the first projection line segment and the third projection point other than the first projection point in the second projection line segment is determined as the first offset distance.

[0106] In the case where the first projection line segment and the second projection line segment overlap, the control component can determine the absolute value of the length difference between the first projection line segment and the second projection line segment as the first offset distance; in the case where the first projection line segment and the second projection line segment do not overlap, the control component can project the first projection line segment onto the straight line where the second projection line segment is located to obtain the third projection line segment, and determine the absolute value of the length difference between the third projection line segment and the second projection line segment as the first offset distance; the control component can also determine the distance from the second projection point to the straight line where the second projection line segment is located as the first offset distance, but this embodiment does not specifically limit this.

[0107] It should be noted that the reference plane can be the first plane where the water outlet is located, the third plane where the image acquisition unit is located, or any other plane other than the first and second planes. The first plane where the water outlet is located is a plane parallel to the diameter of the water outlet and perpendicular to the water outlet direction; the third plane where the image acquisition unit is located is a plane parallel to the first plane.

[0108] Optionally, step S210, determining the first offset distance between the first center position and the second center position, includes steps B11 to B13:

[0109] Step B11: Establish a two-dimensional plane coordinate system in the first plane where the water outlet is located, with the second center position as the origin.

[0110] Step B12: Obtain the projection position of the first center position in the two-dimensional plane coordinate system.

[0111] Step B13: Determine the second offset distance of the projected position relative to the origin as the first offset distance of the first center position relative to the second center position.

[0112] In this embodiment, the control component can also determine the first offset distance through steps B11 to B13. Specifically, a two-dimensional plane coordinate system is established in the first plane where the outlet is located, with the second center position as the origin, including mutually perpendicular X-axis and Y-axis. In this embodiment, the positive directions of the X-axis and Y-axis are not limited.

[0113] In the process of determining the first offset distance based on the two-dimensional plane coordinate system established in step B11, the control component can obtain the projection position of the first center position in the two-dimensional plane coordinate system, and determine the second offset distance of the calculated projection position relative to the origin as the first offset distance of the first center position relative to the second center position.

[0114] Specifically, the control component can determine the second offset distance as a first offset sub-distance in the X-axis direction relative to the origin and a second offset sub-distance in the Y-axis direction relative to the origin. The control component also calculates the distance between the projected position and the origin based on the coordinates of the projected position in the two-dimensional plane coordinate system, and determines this distance as the second offset distance.

[0115] Step S211: Identify the container opening of the target container and the first center position and edge position of the container opening.

[0116] Step S212: Determine the first distance between the edge position of the container opening and the first center position.

[0117] Step S213: Calculate the product of the first distance and the preset coefficient to obtain the first threshold; the preset coefficient is less than or equal to the second threshold.

[0118] In this embodiment of the application, before determining whether the offset of the target container relative to the outlet is greater than the first threshold, the control component may also determine the first threshold through steps S211 to S213.

[0119] Specifically, the control component can identify the container opening of the target container in the target image, the first center position and the edge position of the container opening, and the first distance between the edge position and the first center position based on the target image. Wherein, if the shape of the container opening edge is a perfect circle, the first distance is the radius of the circle; if the shape of the container opening edge is an ellipse or a polygon, the first distance is the shortest distance from the edge of the ellipse or polygon to the first center position.

[0120] It should be noted that, when the thickness of the container opening is not negligible, the edge position is the inner wall edge of the container opening, and the first distance is the distance between the inner wall of the container opening and the first center position.

[0121] The second threshold can be any value greater than 0 and less than 1. For example, the second threshold can be any value among 1 / 2, 2 / 3, and 3 / 5. It is understood that, under the premise of ensuring that the water flowing from the outlet smoothly flows into the container opening, the preset coefficient can be taken as large as possible to reduce the difficulty for users to align the target container and the outlet during the water filling process.

[0122] Step S214: Determine whether the offset is less than or equal to the first threshold.

[0123] Specifically, if the offset is greater than or equal to the first threshold, it indicates that the water flowing from the outlet can smoothly flow into the target container. If the control component determines that the offset is less than or equal to the first threshold, it can execute step S216 to control the water dispenser to turn on the water dispensing function. If the offset is greater than the first threshold, it indicates that the water flowing from the outlet may flow outside the target container. If the control component determines that the offset is greater than the first threshold, it can execute step S215 and not execute the operation of controlling the water dispenser to turn on the water dispensing function.

[0124] Step S215: Do not perform the operation of controlling the water dispenser to turn on the water dispensing function.

[0125] Specifically, if the offset exceeds the first threshold, to prevent water from flowing out of the outlet and scalding the user due to misalignment between the outlet and the target container, the control component may not execute the operation to turn on the water dispenser's water dispensing function.

[0126] Step S216: If the offset is less than or equal to the first threshold, control the water dispenser to turn on the water dispensing function.

[0127] This step can be referred to in the detailed description of step S105, and will not be repeated here.

[0128] Step S217: Determine the second plane where the container opening of the target container is located.

[0129] Step S218: Obtain the second distance between the water surface in the target container and the second plane.

[0130] Step S219: If the second distance is less than or equal to the fourth threshold, control the water dispenser to turn off the water dispensing function.

[0131] In this embodiment, the detection component may further include an ultrasonic scanner for detecting the distance between the water surface in the target container and the container opening.

[0132] Specifically, after the control component controls the water dispenser to turn on the water dispensing function, it can use an ultrasonic scanner to obtain the second distance between the water surface in the target container and the second plane where the container opening is located in real time. If the second distance is less than or equal to the fourth threshold, the control component controls the water dispenser to turn off the water dispensing function, which can prevent the water in the target container from overflowing or splashing out of the target container and causing scalding.

[0133] The second plane is a plane parallel to the diameter direction of the container opening; the fourth threshold can be set to 1cm, 2cm, 3cm, etc., and this application embodiment does not limit this.

[0134] Optionally, the method further includes step C11:

[0135] Step C11: Obtain the target capacity of the target container.

[0136] After controlling the water dispenser to turn on the water dispensing function when the offset is less than or equal to the first threshold as described in step S105, the method further includes:

[0137] Step C12: When the water dispenser reaches the target capacity, control the water dispenser to turn off the water dispensing function.

[0138] In this embodiment, the detection component may further include an ultrasonic scanner for detecting the capacity of the target container.

[0139] Specifically, the control component can use an ultrasonic scanner to detect the maximum capacity of the target container and determine the target capacity of the target container based on the maximum capacity. For example, the target capacity can be 90%, 80%, or 70% of the maximum capacity, etc.

[0140] After the control component obtains the target capacity through step C11, it can control the water dispenser to turn off the water dispensing function after the water volume reaches the target capacity, thus preventing water from overflowing or splashing out of the target container and causing scalding, thereby improving the safety of users when using the water dispenser.

[0141] Optionally, in step S104, if the target container is included in the object being detected, determining the offset of the target container relative to the water dispenser's outlet includes steps A11 to A12:

[0142] Step A11: If the object being detected contains a target container, determine the number of times the target container shakes within a preset time period.

[0143] Step A12: If the number of shaking events is less than or equal to the third threshold, determine the offset of the target container relative to the water outlet of the water dispenser.

[0144] In this embodiment, considering that young children, elderly people, and other users who are unable to care for themselves may experience shaking when using the target container to collect water, potentially leading to scalding. The water dispenser control method provided in this embodiment, when the detected object includes the target container, determines the offset of the target container relative to the water dispenser's outlet by first determining the number of times the target container shakes within a preset time period. If the number of shaking events exceeds a third threshold, the operation to control the water dispenser to start dispensing water is not executed; if the number of shaking events is less than or equal to the third threshold, step A12 is executed to determine the offset of the target container relative to the water dispenser's outlet.

[0145] Specifically, during the execution of step S104, the control component can continuously acquire a first image within the target range using the image acquisition unit, and record the number of times the target container shakes in the first image within a preset time period. Here, shaking of the target container refers to the situation where the target container partially or completely leaves the target range; within the preset time period, a single instance of the target container partially or completely leaving the target range is recorded as one shake; a situation where the target container shakes once, returns to the target range, and then partially or completely leaves the target range again within the preset time period is recorded as two shakes. Thus, the number of times the target container shakes within the preset time period can be obtained.

[0146] The preset time period and the third threshold can be determined according to user needs. For example, the preset time period can be 2s, 5s, 10s, 15s, etc., and the third threshold can be 1, 3, 4, etc. The embodiments of this application do not specifically limit these values.

[0147] If the number of vibrations is less than or equal to the third threshold, the control component can determine the offset of the target container relative to the water outlet of the water dispenser according to the operation corresponding to step S104 or steps S208 to S210. The embodiments of this application will not be described in detail here.

This can avoid the problem of users being scalded by hot water due to accidentally touching the water dispenser's water dispensing switch or due to various reasons causing the water outlet to be misaligned with the target container when dispensing water.
