[0002] With the widespread adoption of smart home appliances, humidifiers have become a core device for improving indoor humidity levels.

[0003] In related technologies, when users add water to a humidifier, they often need to manually turn off the humidifier to stop the fan from working, and then manually turn it back on after adding water to resume the fan's operation.

[0004] The above method of adding water is cumbersome and inefficient. Furthermore, if the user forgets to turn off the fan before adding water, water may splash, compromising the safety of the process. Summary of the Invention

[0006] According to a first aspect of the embodiments of this application, a humidifier control method is provided, comprising: Monitor the user's movement status information within the target area, which is determined based on the location of the humidifier; Based on motion status information, detect whether the user has the intention to add water to the humidifier within the target area; If the system detects that a user intends to add water to the humidifier within the target area, it will reduce the operating power of the humidifier's fan.

[0007] In some embodiments of this application, monitoring the user's movement status information within a target area includes: The radar module in the humidifier acquires the micro-Doppler characteristics of the detected targets within the target area. Based on micro-Doppler characteristics, determine whether the target being detected is a user; If the target is a user, the radar module collects echo signals to monitor the user's movement status within the target area.

[0008] In some embodiments of this application, the target area includes a first area and a second area, the distance between the first area and the humidifier is greater than the distance between the second area and the humidifier, and the motion state information includes the user's first motion state information in the first area and the user's second motion state information in the second area. Based on motion status information, detect whether the user intends to add water to the humidifier within the target area, including: Based on the first motion state information, detect whether the user has the intention to add water to the humidifier within the first area; If the system detects that the user intends to add water to the humidifier in the first area, it then detects that the user intends to add water to the humidifier in the second area based on the second motion state information.

[0009] In some embodiments of this application, the first motion state information includes the user's first motion speed within a first area; Based on the first motion state information, detect whether the user has the intention to add water to the humidifier within the first area, including: If the user's first movement speed in the first area is greater than or equal to a preset speed threshold, it is determined that the user has the intention to add water to the humidifier in the first area.

[0010] In some embodiments of this application, the second motion state information includes the user's second motion speed and dwell time within the second area; If the system detects that the user intends to add water to the humidifier within the first area, based on the second motion state information, it detects whether the user intends to add water to the humidifier within the second area, including: If the user is detected to have the intention to add water to the humidifier within the first area, the user's rate of change of speed is determined based on the first and second movement speeds. If the rate of change of speed is within the preset range and the dwell time is greater than the preset duration, it is determined that the user has the intention to add water to the humidifier in the second area.

[0011] In some embodiments of this application, if it is detected that a user intends to add water to the humidifier within the target area, the operating power of the humidifier's fan is reduced, including: If the system detects that a user intends to add water to the humidifier within the first area, the operating power of the humidifier's fan will be reduced to the first target power, which is not zero. If the system detects that the user intends to add water to the humidifier in the second area, the first target power will be reduced to zero.

[0012] In some embodiments of this application, the method further includes: If the system detects that the user has left the target area, it will increase the operating power of the humidifier's fan according to the preset waiting time.

[0013] In some embodiments of this application, before detecting whether a user intends to add water to the humidifier within the target area based on motion state information, the method further includes: Collect water level information in the humidifier's water tank; Based on motion status information, detect whether the user intends to add water to the humidifier within the target area, including: The system detects whether the water level corresponding to the water level information is lower than the preset water level and obtains the water level detection result. Based on motion status information and water level detection results, the system can detect whether the user intends to add water to the humidifier within the target area.

[0017] In the humidifier control method described above, the humidifier can monitor the user's movement status within a target area and detect whether the user intends to add water to the humidifier. If this intention is detected, the humidifier's fan power is reduced, allowing the fan to be shut off before the user adds water. This eliminates the need for the user to manually turn off the humidifier when adding water, simplifying the process and improving efficiency. Furthermore, reducing the fan's efficiency when the user's intention to add water is detected prevents water from splashing, enhancing safety during the water-adding process.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0020] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

It should be understood that there is no logical or temporal dependency between "first," "second," and "nth," nor does it limit the quantity or execution order. It should also be understood that although the following description uses the terms "first," "second," etc., to describe various objects, these objects should not be limited by the terms.

[0022] These terms are simply used to distinguish one object from another. For example, without departing from the various examples, a first action can be called a second action, and similarly, a second action can be called a first action. Both the first and second actions can be actions, and in some cases, they can be separate and distinct actions.

"Multiple" refers to two or more actions. For example, multiple actions can be two actions, three actions, or any integer number of actions greater than or equal to two.

[0024] Currently, with the widespread adoption of smart home appliances, humidifiers have become a core device for improving indoor humidity levels. In current technology, users often need to manually turn off the humidifier to stop the fan when adding water, and then manually turn it back on after adding water. This method is cumbersome and inefficient. Furthermore, if the user forgets to turn off the fan before adding water, water may splash, compromising the safety of the process.

[0025] To address the problems in the aforementioned related technologies, this application provides a humidifier control method that can reduce the operating efficiency of the humidifier's fan when it detects that a user intends to add water to the humidifier within a target area, thereby preventing water from splashing in the humidifier and improving the safety of the water-adding operation.

[0026] The executor of the above-mentioned humidifier control method can be the humidifier itself, its internal control unit, or a server connected to the humidifier. The following section will elaborate on the humidifier control method using the humidifier as the executor. Figure 1 As shown, Figure 1 This is a flowchart illustrating a humidifier control method provided in an embodiment of this application.

[0027] like Figure 1 As shown, the humidifier control method in this embodiment may include S101 to S103, as follows: S101 monitors the user's movement status information within the target area, which is determined based on the location of the humidifier.

[0028] S102, based on motion status information, detects whether the user has the intention to add water to the humidifier within the target area.

[0029] S103, if it is detected that the user intends to add water to the humidifier in the target area, the operating power of the humidifier's fan is reduced.

[0030] First, the target area can be pre-determined based on the location of the humidifier itself. The target area is a preset area around the humidifier, and the range of the target area can be flexibly set according to actual needs. For example, the target area can be set to an area no more than 1.5 meters away from the humidifier.

[0031] Then, when the user is in the target area, the humidifier can detect whether the user intends to add water to the humidifier within the target area, and thus control the operating power of the humidifier's fan.

[0032] Specifically, the humidifier can monitor the user's motion status information in real time. The motion status information is used to characterize the user's motion behavior characteristics and can reflect the user's intention to add water to the humidifier. The motion status information can include one or more of the following: motion speed, dwell time, and rate of change of speed.

[0033] Furthermore, the humidifier can detect whether the user intends to add water to the humidifier based on the monitored user's movement within the target area. This intention can characterize the user's subjective tendency to add water. For example, if the user's movement speed gradually decreases to a low speed within the target area, it can be determined that the user intends to add water to the humidifier. Conversely, if the user's movement speed remains high within the target area, it can be determined that the user does not intend to add water. As another example, if the user's movement speed gradually decreases to a low speed within the target area and then remains there for a period of time, it can be determined that the user intends to add water to the humidifier.

[0034] If the system detects that a user intends to add water to the humidifier within the target area, the humidifier can reduce the operating power of its internal fan to shut it off before the user performs the water addition operation, thus preventing water from splashing and improving the user's safety during the water addition process.

[0035] Therefore, in the above-described humidifier control method, the humidifier can monitor the user's movement status information within the target area and detect whether the user intends to add water to the humidifier. If this intention is detected, the humidifier's fan power is reduced, allowing the fan to be shut off before the user adds water. This eliminates the need for the user to manually turn off the humidifier when adding water, simplifying the process and improving efficiency. Furthermore, reducing the fan's efficiency when the user's intention to add water is detected prevents water from splashing, enhancing safety during the water-adding process.

[0036] In some embodiments of this application, S101 relates to a scenario where, in addition to the user, the target area may also contain moving objects such as a robot vacuum cleaner or sliding tables and chairs. Therefore, the humidifier can incorporate a radar module to accurately determine whether a detected target is a user, thereby eliminating interference from non-user moving objects and effectively monitoring the user's movement status information in the target area. S101 may include S1011 to S1013, as detailed below.

[0037] S1011 uses the radar module in the humidifier to acquire the micro-Doppler characteristics of the detected target within the target area.

[0038] S1012, based on micro-Doppler characteristics, determines whether the detected target is a user.

[0039] S1013 If the target is a user, monitor the user's movement status information within the target area based on the echo signal collected by the radar module.

[0040] The radar module in the humidifier can acquire the micro-Doppler characteristics of a detected target within the target area. These micro-Doppler characteristics can characterize the motion attributes of the detected target. Specifically, the radar module can transmit continuous electromagnetic wave signals towards the target area and receive the echo signals returned after the target is detected. Then, the signal processing unit within the radar module can extract the Doppler frequency shift component generated by the detected target in the echo signal, thereby obtaining the micro-Doppler characteristics of the detected target.

[0041] Then, the radar module can determine whether the detected target is a user based on its micro-Doppler characteristics. Specifically, the radar module can match the micro-Doppler characteristics of the detected target with a preset user feature model. The user feature model can be a feature module pre-constructed based on the micro-Doppler characteristic patterns corresponding to human vital signs and typical human limb movements. If the matching degree between the micro-Doppler characteristics of the detected target and the preset user feature model is greater than a preset threshold, then the detected target is determined to be a user. When the detected target is a user, the radar module can further analyze the acquired echo signal to extract motion state information such as the user's movement speed, dwell time, or rate of change of speed within the target area, thereby achieving monitoring of the user's motion state information within the target area.

[0042] The radar module in this embodiment can be a millimeter-wave radar sensor operating at 24 Hz. The specific configuration of the radar module in the humidifier is as follows: Figure 2 As shown, Figure 2 This is a schematic diagram of a humidifier provided in an embodiment of this application.

[0043] like Figure 2 As shown, three radar modules 201 can be installed on the top of the humidifier 200. These three radar modules 201 can correspond to different fan-shaped detection areas. By dispersing their layout, they can form a full-range coverage of the top and surrounding space of the humidifier, thereby enabling multi-directional detection of targets in the target area around the humidifier.

[0044] In some embodiments of this application, S102 is involved. When detecting whether the user has the intention to add water to the humidifier in the target area, a two-level detection mechanism based on area division can be adopted to detect the user's intention to add water to the humidifier in different areas. Based on the detected user's intention to add water to the humidifier in different areas, the fan of the humidifier can be controlled in a hierarchical manner.

[0045] The target area can be divided into a first area and a second area, where the distance between the first area and the humidifier is greater than the distance between the second area and the humidifier. For example, the second area can be set to be an area no more than 0.5 meters away from the humidifier, and the first area can be set to be an area more than 0.5 meters but no more than 1.5 meters away from the humidifier. The user's movement status information within the target area can include the user's first movement status information within the first area and the user's second movement status information within the second area. S102 can include S1021 and S1022, as detailed below.

[0046] S1021, based on the first motion state information, detect whether the user has the intention to add water to the humidifier within the first area.

[0047] S1022, if it is detected that the user has the intention to add water to the humidifier in the first area, it is detected that the user has the intention to add water to the humidifier in the second area based on the second motion state information.

[0048] The humidifier can first determine whether the user intends to add water to the humidifier based on the user's first movement state information in the first area. That is, it can detect whether the user intends to add water to the humidifier in the first area.

[0049] If it is initially determined that the user intends to add water to the humidifier—that is, if the user's intention to add water to the humidifier is detected in the first area—then, based on the user's second motion state information in the second area, it can be determined whether the user intends to add water to the humidifier in the second area. Furthermore, based on the detected user's intention to add water to the humidifier in both the first and second areas, the operating power of the humidifier's fan can be reduced.

[0050] In some embodiments of this application, if it is initially determined that the user does not have the intention to add water to the humidifier, that is, the user does not have the intention to add water to the humidifier in the first area, in order to improve the efficiency of detecting the user's intention, it is not necessary to detect whether the user has the intention to add water to the humidifier in the second area, that is, directly determine that the user does not have the intention to add water to the humidifier in the target area.

[0051] Of course, in actual humidifier usage scenarios, there may be situations where a user does not have a clear intention to add water to the humidifier in the first area, but temporarily adds water after entering the second area. Based on this, in some embodiments of this application, detecting the user's intention to add water to the humidifier in the second area may not require referring to the detection results of the intention in the first area; that is, regardless of whether the user has an intention to add water to the humidifier in the first area, the user's intention to add water to the humidifier in the second area is detected.

[0052] In some embodiments of this application, S1021 relates to a first motion state information that may include a user's first motion speed within a first area. The humidifier can detect whether the user intends to add water to the humidifier within the first area based on the user's first motion speed within the first area. Specifically, S1021 may include: determining that the user intends to add water to the humidifier within the first area if the user's first motion speed within the first area is greater than or equal to a preset speed threshold; otherwise, determining that the user does not intend to add water to the humidifier within the first area. This speed threshold can be determined based on common user behavior patterns in humidifier usage scenarios. For example, the speed threshold can be set to 1 m / s, the normal walking speed of an adult approaching a humidifier in a humidifier usage scenario.

[0053] In some embodiments of this application, S1022 is involved. The second motion state information may include the user's second motion speed and dwell time in the second area. The humidifier can detect whether the user has an intention to add water to the humidifier in the second area based on the user's first motion speed in the first area, the user's second motion speed in the second area, and the dwell time in the second area. S1022 may include S10221 and S10222, as detailed below: S10221, if it is detected that the user has the intention to add water to the humidifier in the first area, the user's speed change rate is determined based on the first movement speed and the second movement speed.

[0054] S10222, if the rate of change of speed is within the preset range of the rate of change of speed and the dwell time is greater than the preset time, it is determined that the user has the intention to add water to the humidifier in the second area.

[0055] When the humidifier detects that the user intends to add water to the humidifier within the first area, it can determine the user's rate of change of speed based on the user's first speed within the first area and the user's second speed within the second area. A positive rate of change of speed indicates that the user is accelerating as they pass through the first and second areas, while a negative rate of change of speed indicates that the user is decelerating as they pass through the first and second areas.

[0056] In practical humidifier usage scenarios, when a user needs to add water to the humidifier, their movement is typically slowed down as they pass through the first and second zones. Therefore, the speed change rate range can be determined based on general user behavior patterns; for example, the speed change rate range can be set to [-0.8]. -0.2 ].

[0057] If the user's rate of change of speed is less than the lower limit of the speed change rate range, it indicates that the user decelerated too quickly while passing through the first and second zones. The user may be engaging in non-water-adding behaviors such as avoiding obstacles or making sudden turns, and therefore has no intention of adding water to the humidifier. If the user's rate of change of speed is greater than the upper limit of the speed change rate range, it indicates that the user did not significantly decelerate while passing through the first and second zones, and therefore has no intention of adding water to the humidifier. Conversely, if the user's rate of change of speed is within the speed change rate range, it can be determined that the user may have intended to add water to the humidifier in the second zone.

[0058] Furthermore, in actual humidifier usage scenarios, if a user needs to add water to the humidifier, they will typically linger in the second area to perform this operation, resulting in a certain dwell time. This dwell time is the duration the user spends in the second area. Therefore, the dwell time in the second area can be used to help determine the user's intention to add water to the humidifier. Specifically, if the user's rate of change is within a preset range and the dwell time exceeds a preset duration, it is determined that the user intends to add water to the humidifier in the second area. The preset duration can be determined based on general user behavior patterns; for example, it could be set to 3 seconds.

[0059] In some embodiments of this application, S103 relates to a humidifier that can perform graded control of the humidifier's fan based on the detected user's intention to add water to the humidifier in the first and second areas. Therefore, S103 may include S1031 and S1032, as detailed below: S1031, if it is detected that the user intends to add water to the humidifier in the first area, the operating power of the humidifier's fan is reduced to the first target power, which is not zero.

[0060] S1032, if it is detected that the user has the intention to add water to the humidifier in the second area, the first target power is reduced to zero.

[0061] If the system detects that a user intends to add water to the humidifier within the first area, it can reduce the humidifier's fan power to a first target power, thereby gradually decreasing the fan speed and maintaining low-speed operation. The first target power can be set based on actual needs; for example, it can be set to 30% to 50% of the rated power.

[0062] If the system detects that a user intends to add water to the humidifier in the second area, the first target power can be reduced to zero. This allows the humidifier's fan to be completely shut down before the user performs the water-adding operation, preventing water from splashing and improving the user's safety during the water-adding process.

[0063] In some embodiments of this application, if it is detected that the user does not have the intention to add water to the humidifier in the second area, the first target power of the humidifier's fan can be increased to the initial operating power of the humidifier, which refers to the operating power of the humidifier when the user is not detected entering the target area.

[0064] In some embodiments of this application, after the user completes the water filling operation, they will leave the target area. If the humidifier detects that the user has left the target area, it can resume the normal operation of the humidifier's fan.

[0065] To prevent water from splashing from the humidifier when the fan starts before the user has completely left the target area, the humidifier can increase the fan's operating power after a preset waiting time. Specifically, the current operating power can be restored to the humidifier's initial operating power, which is the operating power the humidifier operates at before detecting the user entering the target area. For example, the preset waiting time can be set to 10 seconds, 15 seconds, etc., and this application does not specify a particular timeframe.

[0066] In some embodiments of this application, S102 is involved, in addition to detecting the user's intention to add water to the humidifier based on the user's movement status information in the target area, the humidifier can also combine the water level information in the humidifier's water tank to further detect the user's intention to add water to the humidifier in the target area.

[0067] Based on this, prior to S102, the aforementioned humidifier control method further includes: collecting water level information in the humidifier's water tank. The humidifier's water tank typically integrates a water level sensor, which collects water level information from the tank. The water level sensor is not limited to capacitive water level sensors, infrared water level sensors, or float-type water level sensors.

[0068] S102 may include S1023 and S1024, as detailed below: S1023, detect whether the water level corresponding to the water level information is lower than the preset water level, and obtain the water level detection result.

[0069] S1024, based on motion status information and water level detection results, detect whether the user has the intention to add water to the humidifier within the target area.

[0070] The preset water level in this embodiment can be the minimum water level required for the humidifier to operate normally, or it can be the minimum water level set by the user based on their own needs. Based on the preset water level, the humidifier can detect whether the water level corresponding to the water level information is lower than the preset water level and obtain the water level detection result.

[0071] Furthermore, the humidifier can detect whether the user intends to add water to the humidifier within the target area based on the water level detection results and the user's movement status information within the target area. Specifically, the humidifier can detect the user's intention to add water to the humidifier within the target area based on both the water level detection results and the user's movement status information within the target area, and then determine whether the user intends to add water to the humidifier within the target area based on the results of the two detections.

[0072] Specifically, when detecting a user's intention to add water to the humidifier within the target area based on water level detection results, if the water level detection result indicates that the corresponding water level is lower than the preset water level, it can be preliminarily determined that the user intends to add water to the humidifier; otherwise, it can be preliminarily determined that the user does not intend to add water to the humidifier. The relevant process for detecting a user's intention to add water to the humidifier within the target area based on the user's movement status information has been explained in the preceding content and will not be repeated here.

[0073] For example, if the humidifier detects the user's intention to add water to the humidifier based on the user's movement status information within the target area, but detects no such intention based on water level detection (i.e., the water level in the tank is higher than a preset level), then it can be determined that the user does not intend to add water to the humidifier within the target area. This is merely one embodiment provided in this application. In practical applications, the detection logic in the humidifier based on the results of the aforementioned two detections can be flexibly configured according to detection requirements to achieve the detection of the user's intention to add water to the humidifier.

[0074] The following is a detailed explanation of the overall process of the humidifier control method described above. Figure 3 As shown, Figure 3 This is a schematic diagram of the overall process of a humidifier control method provided in an embodiment of this application.

[0075] Depend on Figure 3 As shown, the humidifier can first determine whether the target in the target area is a user. If the target is not a user, no further operations are performed. If the target is a user, it can determine whether the user's first movement speed in the first area is greater than or equal to a preset speed threshold. If the user's first movement speed in the first area is not greater than or equal to the preset speed threshold, it is determined that the user does not intend to add water to the humidifier in the first area, and no further operations are performed.

[0076] If the user's first movement speed in the first area is greater than or equal to a preset speed threshold, it is determined that the user intends to add water to the humidifier within the first area, and the operating power of the humidifier's fan is reduced to a first target power. Then, based on the user's first movement speed in the first area and second movement speed in the second area, the speed change rate is determined, and it is judged whether the speed change rate falls within a preset speed change rate range and whether the user's dwell time in the second area exceeds a preset time. If the speed change rate falls within the preset speed change rate range and the user's dwell time in the second area exceeds the preset time, it is determined that the user intends to add water to the humidifier within the second area, and the first target power of the humidifier's fan is reduced to zero. Upon detecting that the user has left the target area, the operating power of the humidifier's fan is increased to the humidifier's initial operating power according to a preset waiting time.

[0077] If the rate of change of speed does not fall within the preset range and / or the user's dwell time in the second area is not greater than the preset duration, it is determined that the user does not have the intention to add water to the humidifier in the second area, and the first target power of the humidifier's fan is increased to the humidifier's initial operating power.

[0078] Therefore, in the above-described humidifier control method, the humidifier can monitor the user's movement status information within the target area and detect whether the user intends to add water to the humidifier. If this intention is detected, the humidifier's fan power is reduced, allowing the fan to be shut off before the user adds water. This eliminates the need for the user to manually turn off the humidifier when adding water, simplifying the process and improving efficiency. Furthermore, reducing the fan's efficiency when the user's intention to add water is detected prevents water from splashing, enhancing safety during the water-adding process.

[0079] In addition, the above-mentioned humidifier control method adopts a two-level detection mechanism based on zone division. By detecting the user's intention to add water to the humidifier in different zones, it realizes graded control of the humidifier's fan, thereby improving the accuracy of the fan control.

[0080] In addition, the above-mentioned humidifier control method can also combine the water level information in the humidifier's water tank to detect the user's intention to add water to the humidifier in the target area. This can avoid misjudgment of the user's intention due to non-water-adding behavior such as passing by, and improve the accuracy of the intention detection.

[0081] In some embodiments of this application, the humidifier may first detect the motion state information of the target within the target area, and detect whether the target has the intention to add water to the humidifier within the target area. Then, it may determine whether the target is a user. If so, the operating power of the humidifier's fan can be controlled according to the detected intention.

[0082] Figure 4 A schematic diagram of a humidifier control device provided in this application embodiment is shown below.
