Description

Technical Field

[0001] This disclosure relates to the field of beauty device technology, and in particular to a mode switching method, system and beauty device based on state recognition. Background Technology

[0002] Radio frequency (RF) beauty devices are instruments that apply power radio frequency energy based on specific waveforms to human skin. When in use, RF output electrodes are applied to human skin to generate RF current, which causes conduction current and displacement current to flow through human skin to form internal heating, thereby achieving the effect of skin care.

[0003] When the radiofrequency current passes through the epidermis and reaches the dermis, it is blocked by the resistance of the cells. The water molecules in the cells instantly oscillate at high speed. The high-frequency oscillation generates heat energy, which denatures the collagen in the dermis, thereby stimulating the body's healing mechanism to generate new collagen from elastic fiber cells.

[0004] In related technologies, beauty devices typically have adjustment buttons on the handle, requiring users to control the device's parameters. Since users have varying facial care needs, they frequently need to switch between different modes during facial treatments. However, the existing technology cannot adaptively match the user's usage patterns. Therefore, improving the flexibility of mode switching in beauty devices is a crucial issue that urgently needs to be addressed. Summary of the Invention

[0005] To overcome the problems existing in related technologies, embodiments of this disclosure provide a mode switching method, system, and beauty device based on state recognition.

[0006] In a first aspect, this application provides a mode switching method based on state recognition, the method being applied to a beauty device, the method comprising: determining that the working mode of the beauty device is in a first preset mode among preset working modes, the preset working modes including the first preset mode and a second preset mode; detecting a first state parameter of the beauty device in the first preset mode; and switching the working mode of the beauty device from the first preset mode to the second preset mode when the first state parameter meets a first preset condition; the first preset condition including the change amplitude of the first state parameter being greater than a first threshold or the first state parameter being less than a first preset value.

[0009] The detection module is used to detect the first state parameter of the beauty device in the first preset mode;

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this invention are used to explain the invention, but are not intended to limit the invention.

[0026] In related technologies, the beauty device has a speed adjustment button on the handle. Users need to adjust the working parameters of the beauty device by pressing the button. Since users have different facial care needs, they need to switch between multiple modes frequently during facial care. However, the related technologies cannot adaptively match the user's usage status of the beauty device.

[0027] This application provides a mode switching method based on state recognition, which can improve the flexibility of mode switching in a beauty device. The mode switching method provided in the embodiments of this disclosure will be described in detail below.

[0028] Figure 1 This is a flowchart illustrating the mode switching method provided in an embodiment of this disclosure. See also... Figure 1 The present disclosure provides a mode switching method based on state recognition, which may include the following steps:

[0029] Step 101: Determine that the beauty device is in the first preset mode among the preset working modes. The preset working modes include the first preset mode and the second preset mode.

[0030] See Figure 2The temperature control method provided in this embodiment can be applied to radio frequency beauty devices. The radio frequency beauty device transmits radio frequency energy to the deep subcutaneous tissue through electrodes, generating an alternating electromagnetic field at a specific depth in the subcutaneous tissue. The alternating electromagnetic field acts on the water molecules in the collagen, and the water molecules generate heat during the vibration and rotation process. The therapeutic effect is achieved through the tissue thermal effect, causing the collagen fibers in the skin tissue to contract.

[0031] An increase in local skin temperature can create pseudo-trauma within the skin tissue. The skin tissue can then repair and regenerate the skin with this pseudo-trauma, and the resulting collagen proliferation can repair the aging and damaged collagen layer.

[0032] See Figure 2 The beauty device is in a preset working mode, which is a facial lifting mode. Within one control cycle of the lifting mode, multiple preset working modes can be included. These multiple preset working modes can include a first preset mode and a second preset mode. The first preset mode is an electroporation mode, and the second preset mode is a microcurrent mode; or, the first preset mode is a microcurrent mode, and the second preset mode is an electroporation mode.

[0033] In this embodiment of the disclosure, microcurrent mode refers to the mode in which the electrodes of the beauty device output microcurrent, radio frequency mode refers to the mode in which the electrodes of the beauty device output radio frequency current, and electroporation mode refers to the mode in which the electrodes of the beauty device output high-voltage pulse current.

[0034] In electroporation mode, the beauty device outputs high-voltage pulsed current through electrodes and flows to the skin. As the high-voltage pulsed current passes through the skin surface, under the action of a high-intensity electric field, it instantly increases the permeability of cell membranes, causing instantaneous changes in the skin structure and achieving the effect of promoting the absorption and penetration of essence.

[0035] Step 102: Detect the first state parameters of the beauty device in the first preset mode.

[0036] For example, in the first preset mode, a sensor is used to detect the first state parameter of the beauty device in real time. The parameter type of the first state parameter may include the load or speed of the beauty device.

[0037] Step 103: When the first state parameter meets the first preset condition, switch the working mode of the beauty device from the first preset mode to the second preset mode; the first preset condition includes the change range of the first state parameter being greater than the first threshold or the first state parameter being less than the first preset value.

[0038] In the lifting mode of facial care, users can start from the initial position of the lifting process, hold the beauty device and slowly lift it upwards while keeping it close to the skin surface. After one upward lift, users can remove the beauty device from the skin surface and move it downwards to the initial position of the lifting process. From the initial position, hold the beauty device close to the skin surface and continue to move upwards for the next lift.

[0039] When the decrease in the load of the beauty device exceeds a first threshold, or when the load of the beauty device falls below a first preset value, it indicates that the user has removed the beauty device from the skin surface. When the decrease in the moving speed of the beauty device exceeds a first threshold, or when the moving speed of the beauty device falls below a first preset value, it indicates that the user has stopped lifting the beauty device upwards.

[0040] For example, the first preset mode is electroporation mode, and the second preset mode is microcurrent mode. In electroporation mode, a sensor is used to detect the load or speed of the beauty device in real time. If the change in the load or speed of the beauty device exceeds a first threshold, the working mode of the beauty device is switched from electroporation mode to microcurrent mode.

[0041] For example, the first preset mode is microcurrent mode, and the second preset mode is electroporation mode; in microcurrent mode, a sensor is used to detect the load or speed of the beauty device in real time. If the change in the load or speed of the beauty device exceeds a first threshold, the working mode of the beauty device is switched from microcurrent mode to electroporation mode.

[0042] The mode switching method provided in this application defines the preset working modes of the beauty device as a first preset mode and a second preset mode. When the beauty device is in the first preset mode, a first state parameter of the beauty device is detected. If the first state parameter meets a first preset condition, the working mode of the beauty device is switched from the first preset mode to the second preset mode. This allows for dynamic matching of the user's usage status of the beauty device, thereby improving the flexibility of mode switching.

[0043] In practical applications, steps A101 to A103 can be implemented using a processor, which can be at least one of the following: Application Specific Integrated Circuit (ASIC), Digital Signal Processor (DSP), Digital Signal Processing Device (DSPD), Programmable Logic Device (PLD), Field Programmable Gate Array (FPGA), Central Processing Unit, Controller, Microcontroller, and Microprocessor.

[0044] Figure 3 A timing diagram of a mode switching method provided in an embodiment of this disclosure is shown below. Figure 3 The operating modes provided in this embodiment include a first preset mode and a second preset mode. When the beauty device is in the first preset mode, the change in the load of the beauty device is detected. If the change in load determines that the electrode is moving away from the skin, it indicates that the facial skin has lost contact with the electrode head, and the first preset mode is stopped. If the change in load determines that the electrode is moving closer to the skin, it indicates that the facial skin has regained contact with the electrode head, and the operating mode of the beauty device is switched from the first preset mode to the second preset mode.

[0045] In practical applications, users can perform multiple lifting and sliding motions on the same skin area. During this process, the device dynamically switches between various preset modes, sampling different modes within a continuous time period to treat the skin area, thus improving the flexibility of mode switching. After completing the treatment on one skin area using various modes, the user can move the device to another skin area and apply the same treatment.

[0046] Figure 4 A timing diagram of a mode switching method provided in an embodiment of this disclosure is shown below. Figure 4 The preset operating modes provided in this embodiment include a first preset mode, a second preset mode, and a third preset mode. The priority order is the first preset mode, the second preset mode, and the third preset mode.

[0047] See Figure 4The system determines that the beauty device is in the second preset mode out of the preset working modes, and detects the change in the load on the device. If the load change indicates that the electrodes are moving away from the skin, the second preset mode is stopped. If the load change indicates that the electrodes are moving closer to the skin, it means that the facial skin and electrode heads are in contact again, and the beauty device's working mode is switched from the second preset mode to the third preset mode.

[0048] Figure 5 A schematic diagram of the load change curve of a beauty device provided in an embodiment of this disclosure is shown below. Figure 5 The device operates in two preset modes: a first preset mode and a second preset mode. The load on the beauty device is monitored in real time. When the load changes, the device calculates whether the load value corresponds to facial skin impedance, thus identifying the working state of the electrode heads. The electrode head working state includes whether the electrodes are close to or far from the skin. When the electrodes are close to the skin, the device is controlled to continuously release energy in the same working mode.

[0049] Figure 6 A schematic diagram of the load change curve of a beauty device provided in an embodiment of this disclosure is shown below. Figure 6 The preset working modes include a first preset mode, a second preset mode, and a third preset mode. The priority order is the first preset mode, the second preset mode, and the third preset mode.

[0050] The system monitors the load on the beauty device in real time. When the load changes, it calculates whether the load value corresponds to facial skin impedance, thereby identifying the working state of the electrode heads. The working state of the electrode heads includes whether the electrodes are close to or far from the skin. When the electrodes are close to the skin, the beauty device is controlled to continuously release energy in the same working mode.

[0051] In one embodiment, when the first state parameter meets the first preset condition, switching the working mode of the beauty device from the first preset mode to the second preset mode may include the following steps:

[0052] Step 201: When the first state parameter meets the first preset condition, detect the movement direction of the beauty device.

[0053] Step 202: If the change in the direction of movement of the beauty device within the preset time is greater than the preset angle, switch the working mode of the beauty device from the first preset mode to the second preset mode.

[0054] Figure 7 This is a schematic diagram illustrating the direction of motion of a beauty device provided in an embodiment of this disclosure. See also... Figure 7If the change in the load of the beauty device exceeds a first threshold, the movement direction of the beauty device is detected. If the change in the movement direction of the beauty device within a preset time period exceeds a preset angle, the working mode of the beauty device is switched from the first preset mode to the second preset mode.

[0055] In one embodiment, after switching from the first preset mode to the second preset mode, the method further includes:

[0056] Step 301: Detect the second state parameter of the beauty device in the second preset mode. The parameter type of the second state parameter includes the load or speed of the beauty device.

[0057] Step 302: When the second state parameter meets the second preset condition, switch the working mode of the beauty device from the second preset mode to the first preset mode; the second preset condition includes the change range of the second state parameter being greater than the second threshold or the second state parameter being less than the second preset value.

[0058] In one embodiment, switching the working mode of the beauty device from the second preset mode to the first preset mode when the second state parameter meets the second preset condition may include the following steps:

[0059] Step 401: When the second state parameter meets the second preset condition, detect the movement direction of the beauty device.

[0060] Step 402: If the change in the direction of movement of the beauty device within the preset time is greater than the preset angle, switch the working mode of the beauty device from the second preset mode to the first preset mode.

[0061] In one embodiment, see Figure 8 The beauty device includes multiple electrodes arranged in an array, comprising a central electrode and peripheral electrodes, with the peripheral electrodes consisting of multiple electrodes arranged around the central electrode; the above mode switching method may further include the following steps:

[0062] Step 501: In the first preset mode, keep the polarity of the central electrode unchanged; determine the positional order of multiple electrodes arranged around the central electrode according to the adjacency relationship of the electrodes in the peripheral electrodes.

[0063] Step 502: Control the electrodes in the peripheral electrodes to switch from the suspended state to the target electrode state in sequence according to the position order and preset time period; the polarity of the target electrode state is opposite to that of the central electrode.

[0064] See Figure 8The electric field strength between the positive and negative electrodes depends on the output voltage and the electrode spacing, being directly proportional to the output voltage and inversely proportional to the electrode spacing; while the factors affecting the action time include pulse width, number of pulses, number of pulse groups, duty cycle, etc.

[0065] In one embodiment, the parameter type of the first state parameter includes the moving speed of the beauty device. The mode switching method provided in this embodiment may further include the following steps: controlling the radio frequency of the radio frequency current output by the beauty device according to the moving speed of the beauty device; the radio frequency of the radio frequency current and the moving speed of the beauty device are negatively correlated.

[0066] The higher the radio frequency (RF) frequency of the radio frequency current, the weaker its penetration into the skin; conversely, the lower the RF frequency, the stronger its penetration. In this embodiment, the RF frequency of the RF current and the moving speed of the beauty device are negatively correlated. When the moving speed of the beauty device is greater, the RF frequency of the RF current is lower, and thus the RF current penetrates the skin more strongly. Conversely, when the moving speed of the beauty device is smaller, the RF frequency of the RF current is higher, and thus the RF current penetrates the skin less strongly.

[0067] The faster the beauty device moves, the higher the user's facial skin temperature. The user consciously holds the device and slides it across different areas of their face to reduce the burning sensation caused by the high skin temperature. Conversely, the slower the beauty device moves, the lower the user's facial skin temperature. The user consciously holds the device and performs skincare on the same area of ​​their face to promote the warming of that area and reduce the burning sensation.

[0068] The faster the beauty device moves, the lower the radio frequency (RF) current frequency. In this case, the RF current penetrates the skin more effectively, resulting in a lower rate of skin warming at the same RF power. Conversely, the slower the beauty device moves, the higher the RF current frequency. In this case, the RF current penetrates the skin less effectively, resulting in a higher rate of skin warming at the same RF power.
