Description

Technical Field

[0001] The present invention relates to a working method of a beauty instrument, a beauty instrument and a storage medium. Background Art

[0002] Radiofrequency beauty devices are a mainstream technology for facial rejuvenation. To achieve their effects of lifting, firming, and wrinkle reduction, they must deliver wide, fast, even, deep, accurate, and long-lasting results.

[0003] Wide - electrode heating area. The heating surface cannot be too small, otherwise the operating efficiency will be too low.

[0004] Fast - the heating rate of the skin is high. If it is too slow, it will also affect the operating efficiency.

[0005] Uniform - The temperature distribution in the heating area is uniform. If it is uneven, the efficacy will be affected due to the presence of low-temperature areas, and the safety will be affected due to the presence of over-temperature areas.

[0006] Deep – The depth of heating applied to the skin. The goal of a radiofrequency beauty device is to heat the dermis and stimulate collagen regeneration. The depth of the facial dermis ranges from 1 to 3mm. If the heating depth does not reach 3mm, the efficacy will be affected.

[0007] Accurate - precise heating temperature for the skin. Collagen begins to be damaged and the wound healing response is initiated at 41-42°C. However, at 43-44°C, heat-induced erythema and a noticeable burning sensation can occur in just a few seconds. For sensitive skin, temperatures exceeding 42°C can aggravate skin sensitivity. Therefore, home radiofrequency beauty devices need to achieve an effective temperature of 41°C while strictly and accurately controlling the upper temperature limit. In addition, the energy required for radiofrequency energy in the eyes is relatively low. On the one hand, the skin in these areas is very thin, allowing radiofrequency energy to easily reach the subcutaneous tissue; on the other hand, radiofrequency energy easily accumulates on spherical tissues and organs, and the skin around the eyes is very fragile. Therefore, the skin around the eyes requires dedicated and precise energy parameters.

[0008] Long--the effective thermal effect on the skin can be maintained for a long enough time. The principle of radio frequency stimulation of collagen regeneration is based on moderate heating to damage collagen. The determining factors of thermal damage to collagen are the heating temperature and duration. Limited by the accuracy requirements of the above heating temperature, the heating temperature of the skin by home radio frequency beauty devices can only be controlled at 41-43°C, which is far from the medical 45-65°C, and the effectiveness is greatly reduced. Therefore, the effect of home radio frequency beauty devices can only be ensured if the heat effect duration is maintained long enough. Often, the areas that users pay attention to are also the areas where sagging and wrinkles are more obvious. It has become an obvious need to extend the duration of radio frequency action for these areas, or even to continue heating to ensure efficacy.

[0009] However, existing home radio frequency beauty devices all have the following problems and cannot meet the aforementioned needs.

[0010] The temperature zones of existing home RF beauty devices are uneven: Existing RF beauty devices are basically equipped with multiple pairs of bipolar RF electrodes. When the power and electrode spacing conditions allow, the bipolar RF electrodes form a nearly semicircular temperature zone, which is wide on the outside and narrow on the inside, and uneven on the inside and outside. When the power and electrode spacing conditions do not allow, a discontinuous temperature zone is formed near the bottom of the two electrodes, which is uneven on the left and right, and the heating depth is shallower. This is especially true for small devices with an output power of only about 10W, such as Figure 1 As shown in Figure 1, it is not easy to form a continuous temperature zone when the electrode spacing is greater than 6 mm, which is manifested as uneven temperature zones. Figure 2 As shown in the figure, when the electrode spacing is 6mm>4mm, a semicircular temperature zone is formed, and there is a significant difference in temperature difference and heating area between the skin surface and 3mm below the skin because the surface and the inside are uneven; when the electrode spacing is less than 4mm, the temperature zone is too concentrated, the temperature rises too quickly, and the skin is easily damaged. Summary of the Invention

[0011] The first technical problem to be solved by the present invention is to provide a working method of a beauty device that can heat the skin more evenly and deeply in response to the above-mentioned prior art.

[0012] The second technical problem to be solved by the present invention is to provide a beauty instrument that applies the working method of the above-mentioned beauty instrument in response to the above-mentioned prior art.

[0014] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a working method of a beauty instrument, characterized in that: when working, the radio frequency electrode group is controlled to act on the skin, and the pulse light is controlled to act on the skin between the two electrodes of the radio frequency electrode group.

[0018] The working method of the deep heating advancement stage is: the wavelength of the pulsed light is adjusted according to the set cycle, so that the pulsed light gradually heats the skin from the surface to the inner layer, thereby deepening the heating depth of the skin;

[0019] The working method in the stable working stage is: detect the temperature of different positions in the skin heating area, and adjust the RF electrode group and the wavelength of the pulse light according to the detected temperature to make the temperature of each position in the skin heating area uniform.

[0020] As an improvement, in the working method of the stable working stage, when the temperature differences at different positions of the detected skin heating area are less than the set threshold, it is judged that the temperatures at various positions of the skin heating area are uniform; otherwise, the working parameters of the radio frequency electrode group and the pulsed light are controlled and adjusted.

[0021] As an improvement, in the working method of the stable working stage, the working parameter of the radio frequency electrode group is adjusted to be the duty cycle of the radio frequency wave signal output by the radio frequency electrode group, and the working parameter of the pulse light is adjusted to be the duty cycle of the pulse light;

[0022] Detecting and obtaining a first temperature T1 near the two electrodes of the radio frequency electrode group, and detecting and obtaining a second temperature T2 at the center of the two electrodes of the radio frequency electrode group;

[0023] If T1≥T0H or T2≥T0H, the control stops the beauty work;

[0024] If T1≤T0L and T2≤T0L, the duty cycle of the radio frequency wave signal output by the radio frequency electrode group is controlled to be increased simultaneously, and the duty cycle of the pulse light is increased;

[0025] Otherwise, if T1<T2, the duty cycle of the radio frequency wave signal output by the radio frequency electrode group is controlled to increase; if T2<T1, the duty cycle of the pulse light is controlled to increase.

[0026] As an improvement, in the working method of the deep heating advancement stage, the wavelength of the pulsed light is periodically adjusted from small to large, or the concave curvature of the focused ultrasonic transducer that generates the pulsed light is periodically adjusted from small to large.

[0027] As an improvement, when the deep heating advancement stage is carried out, after the number of times the pulse light action parameters are adjusted reaches the set number, the work is switched to the stable working stage.

[0028] As an improvement, when the working time of the initial preheating stage reaches the set time, or when it is detected that the temperature difference at different positions of the skin heating area is less than the set threshold, the work will enter the deep heating advancement stage.

[0041] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0042] The beauty device in this embodiment includes a body, a radio frequency component mounted on the body, a multi-wavelength pulsed light source, a temperature sensor, a controller, and a memory. To facilitate user application on the skin, the body is typically provided with an application head having an application surface, and the application ends of the radio frequency component, pulsed light source, and temperature sensor are embedded in the application head's application surface, thereby facilitating application to the skin.

[0043] The RF assembly includes at least one RF electrode group. Multiple temperature sensors are evenly spaced between two RF electrodes in each RF electrode group. These temperature sensors can detect the skin temperature between the two RF electrodes, thereby determining the uniformity of the skin heating temperature. In this embodiment, each RF electrode group includes at least a first temperature sensor positioned proximate to the RF electrode and a second temperature sensor positioned centrally between the two RF electrodes.

[0044] The pulse light source can be a plurality of xenon lamp tubes with different wavelengths, a plurality of LED lamps with different wavelengths, or a plurality of laser light sources with different wavelengths.

[0045] The controller is electrically connected to the RF component, pulse light source, temperature sensor, and memory. The controller can control the working status and working parameters of the RF component, pulse light source, and temperature sensor. At the same time, the controller can also obtain temperature data detected by the temperature sensor. The memory stores control instructions, and the controller can read the control instructions in the memory and execute the working method of the beauty instrument as described below.

[0046] like Figure 3As shown, the beauty device operates as follows: during operation, two RF electrodes in the RF electrode group are controlled to operate. The RF electrode group acts on the skin, generating RF waves between the two RF electrodes, thereby heating the skin between the two RF electrodes. To ensure a relatively large skin surface area, the spacing between the two RF electrodes must be increased. If only the RF electrode group is operated, a high temperature point will form at the two RF electrode locations, while the skin temperature between the two RF electrodes will be significantly lower than that at the two RF electrode locations, resulting in uneven heating. In this embodiment, however, pulsed light is simultaneously controlled to act on the skin between the two electrodes of the RF electrode group. The pulsed light will preheat the tissue in the middle area between the two RF electrodes and then reduce its impedance, thereby guiding the RF energy to concentrate in the middle area. Even with a wider electrode width, the RF can form a continuous current and form a wider and deeper skin heating area. At the same time, because the initial pulsed light concentrates on heating the shallow layer under the stratum corneum, the RF can first form a continuous electric field at the fastest speed and begin to heat the skin. Then, as the wavelength of the pulsed light is adjusted, the pulsed light temperature field can be pushed into the skin, guiding the RF electric field to distribute deeper into the skin until the temperature field continues to act at the targeted depth.

[0047] In addition, in this embodiment, the pulsed light is controlled to act on the skin between the two electrodes of the radio frequency electrode group in a pulse signal. As needed, the pulsed light is a square wave signal or a triangular wave signal. The pulsed light energy outputs energy to the skin intermittently based on the pulses. In this way, when the pulsed light energy output is intermittent, due to the large distance between the radio frequency electrodes and / or the small radio frequency power, the skin temperature zone tends to be distributed near the two radio frequency electrodes. When the pulsed light energy is output, the skin temperature zone is concentrated in the middle of the two radio frequency electrodes. In this way, based on the intermittent output of the pulsed light, the skin temperature zone presents an alternating distribution of "both sides" and "middle", thereby achieving a uniform pulsating heating state of the skin.

[0048] Specifically, the working method of the beauty instrument in this embodiment includes an initial preheating working stage, a deep heating advancing stage, and a stable working stage.

[0049] like Figure 4 and Figure 5 As shown, the working method of the initial preheating stage is as follows: the RF electrode group is controlled to operate at the first frequency and first power corresponding to the set gear, and the pulsed light is controlled to operate at the first wavelength and second power corresponding to the set gear. With the help of the pulsed light, the middle area of ​​the electrode is quickly preheated. The first wavelength used in the initial pulsed light is relatively small, and the heating is concentrated in the superficial dermis. Because the initial focused ultrasound concentrates on heating the superficial layer below the stratum corneum, it reduces the impedance of the superficial dermis, allowing a continuous electric field to be formed more quickly between the two RF electrodes, heating the skin area between the two RF electrodes.

[0050] At the same time, a wider RF spacing or a smaller first power is appropriately set so that when only RF is working, the temperature zone is concentrated in two areas close to the RF electrode side. Since the pulsed light works in a pulsed mode, the temperature zone is close to the sides when the focused ultrasound is temporarily resting, and the temperature zone is concentrated in the middle when the focused ultrasound is working. This achieves pulsating heating from the middle to the sides, obtaining a wider heating range and a more uniform skin heating temperature zone, and reduces the risk of skin burns caused by excessive concentration of the temperature zone. Based on this, it is also beneficial to expand the restrictions on the RF electrode spacing, making the heating area wider.

[0051] When the working time of the initial preheating stage reaches the set time, or when it is detected that the temperature difference at different positions of the skin heating area is less than the set threshold, the work will enter the deep heating advancement stage.

[0052] like Figure 6 and Figure 7 As shown, the working method of the deep heating advancement stage is: adjusting the wavelength of the pulse light according to the set cycle, so that the pulse light gradually heats the skin from the surface to the inner layer and deepens the heating depth of the skin.

[0053] Specifically, the wavelength of the pulsed light is periodically adjusted from small to large. The depth of action on the skin is from shallow to deep. After the pulsed light heats the deeper skin tissue, it reduces its impedance and guides the RF energy generated by the RF component to distribute to the deeper area of ​​the skin, ultimately achieving a deeper heating effect. Similarly, because the pulsed light works in a pulsed manner, the temperature zone is close to the shallow layer when the pulsed light is temporarily resting, and the temperature zone is concentrated in the deep layer when the pulsed light is working. This achieves pulsating heating from the shallow layer to the deep layer, obtains a more uniform temperature zone, and reduces the risk of burns caused by excessive concentration of the temperature zone.

[0054] When the deep heating advancement stage is in progress, after the number of times the pulse light action parameters are adjusted reaches the set number, the work enters the stable working stage.

[0055] The working method in the stable working stage is: detect the temperature of different positions in the skin heating area, and adjust the RF electrode group and the wavelength of the pulse light according to the detected temperature to make the temperature of each position in the skin heating area uniform.

[0056] As an improvement, in the stable operating phase, when the detected temperature differences at different locations within the heated skin area are all less than a set threshold, the temperature at each location within the heated skin area is determined to be uniform. Otherwise, the operating parameters of the RF electrode group and the pulsed light are controlled and adjusted. The RF electrode group operating parameter is the duty cycle of the RF wave signal output by the RF electrode group, and the pulsed light operating parameter is the duty cycle of the pulsed light.

[0057] Specifically, a first temperature T1 close to the two electrodes of the radio frequency electrode group is detected and obtained, and a second temperature T2 located at the center of the two electrodes of the radio frequency electrode group is detected and obtained.

[0058] If T1≥T0H or T2≥T0H, the control stops the beauty work.

[0059] If T1≤T0L and T2≤T0L, the duty cycle of the radio frequency wave signal output by the radio frequency electrode group is controlled to be increased simultaneously, and the duty cycle of the pulse light is increased, thereby increasing the heating temperature.

[0060] Otherwise, if T1 < T2, the duty cycle of the RF wave signal output by the RF electrode group is increased to increase the temperature at the RF electrode position. If T2 < T1, the duty cycle of the pulsed light is increased to increase the heating temperature at the middle position.

[0061] The working method of the beauty instrument in the present invention, while using radio frequency waves to heat the skin, also uses pulsed light to act on the skin between the two electrodes of the radio frequency electrode group, that is, to achieve the systematic effect of radio frequency and ultrasound on the skin, and guide the scattered radio frequency energy gathered at the two radio frequency electrodes to the center through pulsed light. By focusing ultrasound to preheat the dermal tissue with a dominant water content between the two radio frequency electrodes and reduce its impedance, the radio frequency can be guided to form a continuous and effective electric field more quickly, focusing the energy on the target tissue, guiding the rapid generation and uniform distribution of radio frequency energy, and improving the uniformity of skin heating. Based on the working method of this beauty instrument, the distance between the radio frequency electrodes can be appropriately widened, thereby increasing the skin action area. At the same time, based on the adjustment of the pulse light length, the radio frequency energy can also be guided to heat deeper parts of the skin, thereby increasing the heating depth.

[0062] The present invention also relates to a computer-readable storage medium, which stores computer instructions. The computer instructions are used to enable a computer to execute the aforementioned working method of the beauty instrument.
