TECHNICAL FIELD
[0001] The present application relates to a cosmetic instrument and a control method thereof, and a storage medium. BACKGROUND
[0002] Radio frequency cosmetic instrument is the mainstream technology product of facial rejuvenation. In order to achieve the effect of lifting, tightening, wrinkle removal and wrinkle lightening, the radio frequency cosmetic instrument needs to do well in six aspects of wide, fast, uniform, deep, accurate and long.
[0003] Wide - electrode heating area. The heating area cannot be too small, otherwise the operation efficiency will be too low.
[0004] Fast - high heating rate of skin. If it is too low, it will also affect the operation efficiency.
[0005] Uniform - uniform temperature distribution in the heating area. If it is not uniform, on the one hand, it will affect the effect because of the existence of low temperature area, and on the other hand, it will affect the safety because of the existence of over temperature area.
[0006] Deep - heating depth of skin. The function target of radio frequency cosmetic instrument is to heat the dermis layer and stimulate collagen regeneration. The depth of human facial dermis layer is not equal to 1-3mm, if the heating depth does not reach 3mm, the effect will be affected.
[0007] Accurate - accurate heating temperature of skin. Collagen starts to be damaged and initiates wound healing response at 41-42℃, but at 43-44℃, only a few seconds can cause thermal erythema and obvious burning sensation, and more than 42℃ will increase the sensitivity of sensitive skin. Therefore, the household radio frequency cosmetic instrument needs to strictly and accurately control the upper limit of temperature while reaching the effective temperature of 41℃. In addition, the energy required by radio frequency energy in the eye area is relatively low. On the one hand, the skin in these parts is very thin, and the radio frequency energy is easy to reach the subcutaneous tissue; on the other hand, the radio frequency energy is easy to gather on the spherical tissue organs, and on the other hand, the skin in the eye area is very fragile. Therefore, the skin in the eye area needs to set special accurate energy parameters.
[0008] Long - the effective heat effect on the skin can be maintained for a long time. The principle of radio frequency stimulating collagen regeneration is based on moderate heating damage to collagen. The determining factor of collagen thermal damage is heating temperature and time, which is limited by the accuracy requirement of heating temperature. Therefore, the heating temperature of household radio frequency cosmetic instrument can only be controlled at 41-43℃, which is far from the medical 45-65℃, and the effectiveness is greatly discounted. Therefore, only by keeping the heating time long enough, can the effect of household radio frequency cosmetic instrument be ensured. Often the parts that users pay attention to are also the parts where the sagging and wrinkle problems are more obvious. For these parts, the radio frequency action time is prolonged, and even the heating is continuously stopped, so as to ensure the effect, which is also the obvious demand.
[0009] Existing beauty devices typically use single-wavelength radio frequency (RF) electrodes, which presents the following problems: low-frequency heating is deep but slow, resulting in low operational efficiency; while high-frequency heating is fast but shallow, failing to effectively stimulate collagen regeneration in the dermis, and the concentrated heat on the surface can easily cause burns. Furthermore, due to the skin's high impedance, this RF approach initially generates heat in the stratum corneum beneath the two electrodes. As the stratum corneum is heated and its impedance decreases, the heat diffuses further, reducing the impedance of the dermis and gradually advancing towards the center, ultimately resulting in a relatively slow overall process. Summary of the Invention
[0010] The first technical problem to be solved by the present invention is to provide a beauty device that heats up faster, deeper, wider and more evenly than the above-mentioned prior art.
[0011] The second technical problem to be solved by the present invention is to provide a working method for a beauty device that can achieve radio frequency heating with a large working area, faster, more uniform and deeper, in contrast to the above-mentioned prior art.
[0012] The third technical problem to be solved by the present invention is to provide a storage medium that stores computer instructions that can be executed to implement the working method of the aforementioned beauty device, in contrast to the prior art.
[0013] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a beauty device, including a body with a working surface, characterized in that: at least two sets of electrode pairs with varying working frequencies are arranged sequentially along one direction on the working surface, and during beauty work, the electrode pairs are controlled to work alternately and cyclically in order of working frequency from high to low.
[0014] Preferably, the electrode pair with the lower operating frequency is located outside the electrode pair with the higher operating frequency.
[0015] Optionally, each electrode pair includes a first electrode and a second electrode;
[0016] The first electrode and the second electrode are parallel linear electrodes; or
[0017] The first electrode and the second electrode are concentric ring electrodes.
[0018] Preferably, the distance between the first electrode and the second electrode in a high-frequency working electrode pair is smaller than the distance between the first electrode and the second electrode in a low-frequency working electrode pair.
[0019] Preferably, the width of the first electrode and the second electrode is A, where 2mm ≤ A ≤ 5mm;
[0020] The distance between the first and second electrodes in each electrode pair is B, where 2mm ≤ B ≤ 7mm.
[0021] Preferably, a temperature detector is provided on the working surface corresponding to the working area of each pair of electrodes.
[0022] The technical solution adopted by the present invention to solve the second technical problem mentioned above is: a working method of a beauty instrument, characterized in that: a beauty instrument as described above is used;
[0023] When starting the beauty treatment, first control the electrode pair with the highest working frequency to work, and then control each group of electrode pairs to work alternately in order of working frequency from high to low. After a group of electrode pairs reaches the set conditions, it stops working and starts working on the next group of electrode pairs.
[0024] Alternatively, the setting conditions are that the temperature of the working area of the current working electrode reaches the target temperature, and / or the working time of the current working electrode reaches the target time.
[0025] To ensure safety, the temperature T of the area where the electrode pair is currently working on the user's skin is monitored in real time during the beauty treatment. If T reaches the set safety warning temperature, the power of the current working motor pair is reduced; or the current working electrode pair is stopped and the next set of motor pairs is started.
[0026] The technical solution adopted by the present invention to solve the third technical problem mentioned above is: a computer-readable storage medium, characterized in that: the computer-readable storage medium stores computer instructions, which are used to cause the computer to execute the aforementioned beauty device working method.
[0027] Compared with existing technologies, the advantages of this invention are as follows: The beauty device and its working method of this invention include multiple sets of electrode pairs with different working frequencies. During beauty treatment, the device sequentially controls each set of electrode pairs to work alternately and cyclically according to a working frequency from high to low. This allows for rapid heating of a specific area and reduction of skin resistance, followed by gradual heating of the dermis. This achieves synergy between the high and low working frequency electrode pairs, not only increasing the area of action on the skin but also enabling faster, deeper, wider, and more even heating of the skin. Attached Figure Description
[0028] Figure 1 This is a perspective view of the beauty device in an embodiment of the present invention.
[0029] Figure 2 This is a perspective view of a beauty device with an electrode of another shape according to an embodiment of the present invention. Detailed Implementation
[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0031] likeFigure 1 and Figure 2 As shown, the beauty device in this embodiment includes a body 1 with a working surface 11. At least two sets of electrode pairs 2 with varying working frequencies are sequentially arranged on the working surface 11 along one direction. The number of electrode pairs 2 is specifically set according to the area of the working surface 11 and the desired effect. In this embodiment, three sets of electrode pairs 2 are provided, with working frequencies of 0.5MHz, 1MHz, and 2MHz for each set.
[0032] The distribution direction of these frequency-varying electrode pairs 2 on the working surface 11 can be sequentially arranged according to the required heating sequence. In order to improve the uniformity of heating, in this embodiment, the distribution direction of these frequency-varying electrode pairs 2 on the working surface 11 is from the center to the outer edge, and the electrode pairs 2 with lower operating frequencies are located outside the electrode pairs 2 with higher operating frequencies. That is, the closer the electrode pairs 2 are to the edge of the working surface 11, the lower their operating frequency.
[0033] Each electrode pair consists of a first electrode and a second electrode. The shapes of the first and second electrodes are specifically set as needed. For example... Figure 1 As shown, the first electrode and the second electrode are parallel linear electrodes; Figure 2 As shown, the first and second electrodes may be concentrically arranged ring electrodes. When selecting ring electrodes, they can be circular, rectangular, triangular, or irregularly shaped rings, etc. The width of the first and second electrodes is A, where 2mm ≤ A ≤ 5mm. In this embodiment, it is preferred that the width of the first and second electrodes in each electrode pair 2 is 3mm.
[0034] Furthermore, the spacing between the first and second electrodes in the high-frequency working electrode pair 2 is smaller than that in the low-frequency working electrode pair 2. The spacing between the first and second electrodes in each electrode pair 2 is B, where 2mm ≤ B ≤ 7mm. The spacing between the first and second electrodes in each electrode pair 2 is selected within this range. The higher the operating frequency and the smaller the electrode spacing, the faster the heating. Thus, when the high-frequency electrode pair 2 is working, the skin area it acts on can be heated rapidly, thereby reducing skin resistance. Conversely, the lower the operating frequency and the larger the electrode spacing, the deeper the heating depth, which is beneficial for heating the dermis layer of the skin.
[0035] In addition, in order to obtain the temperature of the skin area in a timely manner and avoid burns or inadequate skin treatment, a temperature detector is set on the working surface 11 corresponding to the working area of each group of electrode pairs 2. The temperature sensor can be an infrared temperature sensor or a thermocouple, etc., to detect the temperature of the skin in the working area of each group of electrode pairs 2 in real time.
[0036] The working method of the aforementioned beauty device is as follows.
[0037] During the beauty treatment, the electrode pairs 2 are controlled to work alternately in descending order of operating frequency. Specifically, when starting the beauty treatment, the electrode pair 2 with the highest operating frequency is controlled first. Then, the electrode pairs 2 are controlled to work alternately in descending order of operating frequency. Each electrode pair 2 stops working after reaching a set condition, and the next electrode pair 2 is activated. In this embodiment, the electrode pairs 2 are controlled to work alternately in the following frequency order: 2MHz → 1MHz → 0.5MHz.
[0038] Low-frequency electrode pairs 2 result in more dispersed heating energy, slower temperature rise, and lower operational efficiency. High-frequency electrode pairs 2 heat quickly but superficially, achieving rapid temperature rise but failing to effectively stimulate collagen regeneration in the dermis, and the concentrated heat on the surface can easily cause burns. This beauty device's working method involves first activating the central, higher-frequency electrode pair 2. Because of the higher frequency and smaller electrode spacing, heating is faster, allowing the skin tissue in the central area to heat up first and reducing skin impedance in that area. Then, the peripheral, lower-frequency electrode pairs 2 are activated. Because of the lower frequency and larger electrode spacing, heating is deeper. Since the skin impedance in the central area has already decreased, the lower-frequency electrode pairs 2 can more quickly form a continuous electric field, heating the dermis. Through the alternating and synergistic work of multiple frequency electrode pairs 2, rapid and deep skin heating is achieved, more effectively stimulating collagen regeneration.
[0039] As needed, the aforementioned settings can be set to the temperature of the working area of the current working electrode pair 2 reaching the target temperature, and / or the working time of the current working electrode pair 2 reaching the target time.
[0040] To ensure safety, during the beauty treatment, the temperature T of the area where the current working electrode pair 2 is applied on the user's skin is monitored in real time. If T reaches the set safety warning temperature, the power of the current working motor pair is reduced; or the current working electrode pair 2 is stopped and the next set of motor pairs is started. This achieves a uniform temperature field across the entire skin application surface.
[0041] The beauty device of this invention is equipped with multiple sets of electrode pairs 2 with different working frequencies. During the beauty treatment, the device controls each set of electrode pairs 2 to work alternately and cyclically in descending order of working frequency. This allows for rapid heating of a specific area and reduction of skin resistance, followed by gradual heating of the dermis layer. This achieves synergy between the high and low working frequency electrode pairs, increasing the area of action on the skin and enabling faster, deeper, wider, and more even heating.
[0042] The present invention also relates to a computer-readable storage medium storing computer instructions for causing a computer to perform the aforementioned beauty device operating method.
