Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0034] As mentioned in the background section, existing atomizing devices suffer from the problem of difficulty in precisely controlling the atomization volume. The inventors' research revealed that this problem arises because the atomization volume of existing atomizing devices is often a fixed value, such as atomizing beauty devices and atomizing skincare devices. When the user is close to the atomizing device, the atomization volume is too large, causing liquid to accumulate on the user's skin. When the user is far from the atomizing device, the atomization volume is too small, preventing the aerosol from reaching the user's skin.

[0035] To address the above problems, embodiments of the present invention provide a method for controlling the amount of atomization. Please refer to [link to relevant documentation]. Figure 1 The control method includes steps S102 to S106.

[0036] S102, obtain the atomization distance between the atomizing device and the atomizing object.

[0037] It is understood that the atomized object refers to the target area of ​​the atomizing device, such as the user's hands, face, or other skin. The problem in the background technology is that the atomization amount does not adjust with changes in atomization distance, necessitating the acquisition of the atomization distance before adaptive adjustments to the atomization amount can be made. Optionally, the atomization distance can be obtained using a ranging sensor, such as an ultrasonic ranging sensor or an infrared ranging sensor. To obtain precise atomization distances for different user-required atomized areas, an image acquisition device and a position adjustment device can be installed on the atomizing device. The position adjustment device is used to adjust the ranging direction of the ranging sensor. The image acquisition device is used to acquire user images. The user image is acquired through the image acquisition device; image recognition processing is performed on the user image based on the area selection command to determine the location of the target area; the position adjustment device is controlled based on the location of the target area to ensure the ranging sensor points towards the target area. The user can send area selection commands to the atomizing device through interaction.

[0038] S104, determine the target atomization power based on the atomization distance.

[0039] In this embodiment, when the atomization distance is greater than or equal to a first threshold, the target atomization power is the maximum atomization power of the atomizing device. When the atomization distance is less than the first threshold, the target atomization power is determined based on the positive correlation between atomization distance and atomization power. It can be understood that the first threshold is the farthest atomization distance at which the atomizing device can effectively act on the atomized object. Considering the upper limit of the atomization power of the atomizing device, the waste of energy due to excessive atomization power, and the fact that much aerosol will dissipate into the air, resulting in the atomization medium not being effectively utilized, when the atomization distance is above the first threshold, it is impossible to ensure that the atomized object is effectively acted on by the aerosol by further increasing the power of the atomizing device. In some embodiments, a prompt signal is issued when the target atomization power is less than or equal to the maximum atomization power. Since it is difficult for the user to accurately perceive the distance between themselves and the atomizing device, a prompt signal can be used to notify the user that the atomization distance between them and the atomizing device is too far, and the user needs to adjust their position. The prompt signal can be issued by a reminder unit installed on the atomizing device, which can be a buzzer, a vibration motor, and / or an LED light.

[0040] S106, control the power of the atomizing device according to the target atomizing power, so as to adjust the atomization amount of the atomizing device.

[0041] Specifically, the atomizing device includes an atomizing unit, which atomizes the atomizing medium. The higher the power of the atomizing unit, the greater the atomization volume of the atomizing device. Therefore, the atomization volume of the atomizing device can be adjusted by changing the power of the atomizing unit. Furthermore, the above steps can be repeated multiple times throughout the user's use of the atomizing device, allowing for real-time acquisition of the atomization distance and adjustment of the target atomization power, thus achieving dynamic adjustment of the atomization volume.

[0042] Based on the control method of the atomizing device in this embodiment, when the atomization distance is less than a first threshold, the power of the atomizing device is increased to adaptively adjust the atomization amount, ensuring that the aerosol can effectively act on the atomized object and avoiding problems such as liquid accumulation due to being too close to the atomized object or the aerosol failing to contact the atomized object due to being too far away. When the atomization distance is greater than or equal to the first threshold, the atomizing device is maintained at its maximum atomization power, which avoids waste of atomizing medium and energy, thereby saving energy and reducing the amount of atomizing medium used.

[0043] In one embodiment, the step of controlling the power of the atomizing device according to the target atomization power further includes: if the atomization distance is greater than a first threshold for a preset time, then turning off the atomizing device. It is understood that if the atomization distance is greater than the first threshold for a long period, the atomizing device will be difficult to effectively function for the user, wasting energy and failing to achieve good results. Therefore, in the situation described in this embodiment, turning off the atomizing device achieves the effect of saving energy. In one specific embodiment, the preset time is 30 seconds.

[0044] In one embodiment, steps S202 and S204 are included before the step of determining the target atomization power based on the atomization distance.

[0045] S202, obtain parameters that affect atomization.

[0046] Factors affecting atomization include environmental parameters and / or the type of atomizing medium. Specifically, environmental parameters can be physical quantities such as temperature and humidity outside the atomizing device that affect the atomization rate of the atomizing medium. Additionally, the atomization rates of various atomizing media under the same environmental parameters and power of the same atomizing device can be tested, and those with similar atomization rates can be grouped into the same atomizing medium type. As explained above, when the power of the atomizing devices is the same, but the factors affecting atomization are different, the atomization rates of the atomizing media will all be different. Environmental parameters can be obtained using temperature sensors, humidity sensors, and other appropriate sensors. Commonly used atomizing media types can be categorized and included in the product manual, allowing users to input the atomizing medium type through interaction with the atomizing device. Different atomizing media types contain specific chemical components; therefore, electrochemical sensors can be installed in the atomizing device to detect the composition of the atomizing medium, enabling the device to automatically identify the atomizing medium type. Taking environmental parameters including temperature as an example, for temperatures T1 > T2, before the target atomization power reaches its maximum, the candidate curve L1 corresponding to temperature T1 is higher than the candidate curve L2 corresponding to temperature T2. That is, before the target atomization power reaches its maximum, for the same atomization distance, the target atomization power of candidate curve L1 is higher than that of candidate curve L2. Taking environmental parameters including humidity as an example, for humidity M1 > humidity M2, before the target atomization power reaches its maximum, the candidate curve L1 corresponding to humidity M1 is lower than that of candidate curve L2 corresponding to humidity M2. That is, before the target atomization power reaches its maximum, for the same atomization distance, the target atomization power of candidate curve L1 is lower than that of candidate curve L2.

[0047] S204: Select the curve that corresponds to the atomization parameters from multiple candidate curves as the control curve.

[0048] The control curve is used to obtain the target atomization power based on the atomization distance. It can be understood that the control curve reflects the one-to-one correspondence between atomization distance and target atomization power. In this embodiment, determining the target atomization power based on atomization distance is achieved through the control curve. However, since the atomization parameters affecting the atomization device vary depending on the user's usage, multiple candidate curves can be stored in the atomization device. Each candidate curve is obtained through experiments and analysis based on its corresponding atomization parameters. After acquiring the atomization parameters, the atomization device can select one of these candidate curves as the control curve, enabling the atomization device to accurately select the target atomization power under various environments and atomization media types.

[0049] In one embodiment, the control curve includes a first control curve, see [link to relevant documentation]. Figure 3 The first control curve is:

[0050]

[0051] In the formula, x is the atomization distance, y(x) is the target atomization power corresponding to the atomization distance, D1 is the first threshold, and W max For maximum atomization power, f1(x) reflects the positive correlation between atomization distance and atomization power, and the slope of f1(x) decreases as the atomization distance increases. It can be understood that when the atomization distance is less than the first threshold, the target atomization power increases non-linearly with increasing atomization distance. When the atomization distance is small, the target atomization power increases rapidly initially, preventing users from experiencing insufficient atomization at the beginning. Each candidate curve can have a similar shape to the first control curve, the difference being the different parameters of f1(x) and / or the first threshold in each candidate curve. The parameters in each f1(x) can be obtained by fitting experimental data. Fitting can be achieved using neural networks or machine learning algorithms.

[0052] In one embodiment, the control curve includes a second control curve; see [link to relevant documentation]. Figure 4 The second control curve is:

[0053]

[0054] In the formula, x is the atomization distance, y(x) is the target atomization power corresponding to the atomization distance, D1 is the first threshold, and W maxFor maximum atomization power, f2(x) reflects the positive correlation between atomization distance and atomization power, and the slope of f2(x) remains constant. It can be understood that when the atomization distance is less than the first threshold, the target atomization power increases linearly with increasing atomization distance, ensuring a uniform change in atomization volume as the atomization distance changes. Each candidate curve can have a similar shape to the second control curve, the difference being the different parameters of f2(x) and / or the first threshold in each candidate curve. The parameters in each f2(x) can be obtained by fitting experimental data.

[0055] In one embodiment, the atomizing device includes an atomizing unit and a driving unit. The driving unit outputs a driving signal, and the atomizing unit atomizes the atomizing medium according to the driving signal. The step of controlling the power of the atomizing device according to a target atomizing power includes: outputting a control signal to the driving unit according to the target atomizing power. The control signal is used to adjust the driving signal to adjust the power of the atomizing unit. It can be understood that the power supply of the atomizing device outputs a driving signal to the atomizing unit through the driving unit; by changing the control signal to change the driving signal, the power of the atomizing element can be adjusted.

[0056] It should be understood that, although Figure 1 and Figure 2 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figure 1 and Figure 2 At least some of the steps in the process may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but may be executed at different times. The execution order of these steps or stages is not necessarily sequential, but may be executed in turn or alternately with other steps or at least some of the steps or stages in other steps.

[0057] This invention also provides an atomizing device; please refer to [link / reference]. Figure 5The atomizing device includes an atomizing unit 10, a ranging unit 30, and a controller 50. The atomizing unit 10 is used to atomize the atomizing medium. The atomizing unit 10 can be based on principles such as ultrasonic atomization, mesh atomization, or compression atomization. The atomizing medium can be a mixture of water, various skincare essential oils, skincare liquids, etc. The ranging unit 30 is used to detect the atomization distance between the atomizing device and the atomized object. In one specific embodiment, the ranging unit 30 includes an infrared ranging sensor, an ultrasonic ranging sensor, and / or a laser distance sensor. The controller 50 is used to control the power of the atomizing unit 10 to adjust the atomization amount of the atomizing device. It includes a memory and a processor. The memory stores a computer program. When the processor executes the computer program, it performs the following: obtaining the atomization distance between the atomizing device and the atomizing object; determining the target atomization power based on the atomization distance; wherein, when the atomization distance is greater than or equal to a first threshold, the target atomization power is the maximum atomization power of the atomizing device, and when the atomization distance is less than the first threshold, the target atomization power is determined based on the positive correlation between the atomization distance and the atomization power; and controlling the power of the atomizing device based on the target atomization power to adjust the atomization amount of the atomizing device.

[0058] Based on the atomizing device in this embodiment, when the atomization distance is less than a first threshold, the power of the atomizing device is increased to adaptively adjust the atomization amount, ensuring that the aerosol can effectively act on the atomized object and avoiding problems such as liquid accumulation due to being too close to the atomized object or the aerosol failing to contact the atomized object due to being too far away. When the atomization distance is greater than or equal to the first threshold, the atomizing device is maintained at its maximum atomization power, which avoids wasting atomizing medium and energy, thereby saving energy and reducing the amount of atomizing medium used.

[0059] In one embodiment, the controller 50 is also used to implement the steps in any of the above-described control method embodiments of the atomizing device.

[0060] In one embodiment, the atomizing device further includes a driving unit. The driving unit outputs a driving signal, and the atomizing unit 10 atomizes the atomizing medium according to the driving signal. For a specific embodiment, please refer to... Figure 6The driving unit includes a boost converter chip U4. The DC-EN pin of controller 50 is connected to the control terminal of switching transistor Q4 via resistor R18. The source of switching transistor Q4 is grounded. The drain of switching transistor Q4 is connected to the control terminal of switching transistor Q3 and to the power supply VBAT_OUT of the atomizing device via resistor R15. The source of switching transistor Q3 is connected to VBAT_OUT. The drain of switching transistor Q3 is grounded via capacitors C11, C12, and C14. The drain of switching transistor Q3 is also connected to the input pin IN and the enable pin EN of boost converter chip U4. The drain of switching transistor Q3 is also connected to the LX pin of boost converter chip U4 via inductor L1. The GND pin of boost converter chip U4 is grounded, and the LX pin of boost converter chip U4 is connected to the input terminal of Schottky diode D1. The output of Schottky diode D1 is grounded via resistors R14 and R19, and also via capacitors C15 and C16. The output of Schottky diode D1 outputs a drive signal to atomizing unit 10 via resistor R20. The VDAJ_PWM pin of controller 50 is connected to the common terminal of resistors R14 and R19 via resistors R17 and R16, and then connected to the feedback pin FB of boost chip U4 via the common terminal of resistors R14 and R19. The common terminal of resistors R17 and R16 is also grounded via capacitor C13.

[0061] The circuit described above works as follows: Controller 50 enables boost chip U4 via the DCDC_EN pin, and then adjusts the control signal output by the VADJ_PWM pin to change the drive signal output by boost chip U4. Controller 50 obtains the voltage and current of the drive signal by connecting the ADC sampling pin to the two ends of resistor R20, calculates the real-time power of atomizing unit 10, and determines whether atomizing unit 10 has reached the target atomization power based on the real-time power of atomizing unit 10.

[0062] Please see Figure 7 This invention provides a device for controlling the amount of atomization. The device includes a distance acquisition module 120, a target atomization power determination module 140, and an adjustment module 160. The distance acquisition module 120 acquires the atomization distance between the atomizing device and the atomized object. The target atomization power determination module 140 determines the target atomization power based on the atomization distance. Specifically, when the atomization distance is greater than or equal to a first threshold, the target atomization power is the maximum atomization power of the atomizing device; when the atomization distance is less than the first threshold, the target atomization power is determined based on the positive correlation between atomization distance and atomization power. The adjustment module 160 controls the power of the atomizing device according to the target atomization power to adjust the amount of atomization.

[0063] Based on the atomization quantity control device in this embodiment, when the atomization distance is less than a first threshold, the power of the atomizing device is increased to adaptively adjust the atomization quantity, ensuring that the aerosol can effectively act on the atomized object and avoiding problems such as liquid accumulation due to being too close to the atomized object or the aerosol failing to contact the atomized object due to being too far away. When the atomization distance is greater than or equal to the first threshold, the atomizing device is maintained at maximum atomization power, which can avoid wasting atomization medium and energy, thereby saving energy and reducing the amount of atomization medium used.

The control curve is used to obtain the target atomization power based on the atomization distance.

[0065] In one embodiment, the atomizing device includes an atomizing unit 10 and a driving unit.
