[0036] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0037] The scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0039] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0040] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0041] Please refer to Figures 1 to 3 The present invention proposes a beauty instrument 100, including a shell 10, a circuit component 20 and an electrode component 30. A beauty head 11 is formed at one end of the shell 10; the circuit component 20 is arranged in the shell 10; the electrode component 30 is at least partially exposed outside the beauty head 11 and is electrically connected to the circuit component 20. The electrode component 30 is used to output radio frequency current to the skin.

[0042] The length of the housing 10 is 19mm-39mm, the width is 19mm-39mm, and the height is 93mm-113mm. For example, the length of the housing 10 can be 20mm, the width is 20mm, and the height is 95mm. The beauty instrument 100 of this size is relatively small and relatively high in height, and can accommodate internal structures such as batteries, circuit boards and other components, and the smaller length and width are convenient for handheld operation; the length of the housing 10 is 29mm, the width is 29mm, and the height is 103mm. This size has a certain area on the plane, and the placement is relatively stable. At the same time, the height is moderate, and the design is more conducive to accommodating internal components with various functions, and the user can also control it well when holding it; the length of the housing 10 is 38mm, the width is 38mm, and the height is 110mm. This beauty instrument 100, which is close to the upper limit of the size, can accommodate a larger capacity battery or a more complex circuit system inside, and the larger plane size can also make the beauty instrument 100 more stable in contact with the skin during use. In addition, the length and width of the shell 10 can also be of different sizes, for example, the length is 25mm, the width is 30mm, and the height is 98mm. The use of different lengths and widths can make the shape of the beauty instrument 100 more personalized. This asymmetrical design is more attractive in appearance. At the same time, it can also be reasonably laid out according to the actual shape of the internal components, making the internal space more efficiently utilized.

[0043] Of course, the length, width and height of the housing 10 are merely exemplary and may be other sizes within a range of values, which are not limited in the embodiments of the present application.

[0044] In this embodiment, the length of the housing 10 is in the range of 19 mm to 39 mm, and the width is in the range of 19 mm to 39 mm, so that the beauty instrument 100 is relatively small in the horizontal direction. Compared with those large beauty instruments, the beauty instrument 100 of this size can be easily held in the hand, and is very convenient in terms of gripping with the palm and manipulation with the fingers. In daily travel, the beauty instrument 100 can be more easily placed in an ordinary cosmetic bag or handbag. For example, it can be easily placed in the compartment of a common small cosmetic bag, and carried together with cosmetics and tools such as lipstick and powder, without taking up too much space, and it is convenient for users to switch and use it at any time as needed during the makeup process.

[0045] For example, before using foundation, the user can first use the beauty instrument 100 to take care of the face, and then perform makeup and other operations. The entire operation process is smooth and natural, and there will be no operational inconvenience caused by the excessive size of the beauty instrument 100.

[0046] The height of the housing 10 is between 93 mm and 113 mm, which is not too long, so that the beauty instrument 100 can be placed in a bag more regularly, and will not protrude from the edge of the bag due to being too long, reducing the risk of damage due to collision. Moreover, when traveling, whether it is placed in a small corner of a suitcase or in a small backpack, it is relatively convenient to carry, which can meet the needs of users for beauty care at any time during the journey.

[0047] Since the size of the beauty instrument 100 is relatively moderate, it is relatively easy for the user to hold the beauty instrument 100 for operation. The hand can hold the housing 10 well, and it will not be difficult to control because the beauty instrument 100 is too large, nor will it feel loose to hold because it is too small. For beauty treatments that require delicate operations on the face and other parts, such as using the electrode assembly 30 to output radio frequency current in areas such as the eye area and the corners of the mouth, the appropriate size allows the user to more accurately control the movement direction and strength of the beauty instrument 100.

[0048] In this embodiment, the size of the beauty head 11 (affected by the size of the housing 10) is also relatively suitable, and can be easily fitted to different parts of the skin. For example, when massaging larger areas such as the cheeks and forehead, the beauty head 11 can cover an appropriate area to reduce the operation time; and when treating relatively delicate areas such as the sides of the nose and around the eyes, it can also be flexibly rotated and adjusted in angle to ensure good contact between the electrode assembly 30 and the skin and effectively output radio frequency current.

[0049] In addition, the appropriate size of the beauty head 11 is also conducive to close contact with the skin, ensuring that the radio frequency current can effectively penetrate the stratum corneum of the skin and stimulate the regeneration of collagen, thereby achieving beauty effects such as firming the skin and reducing wrinkles. Moreover, during the beauty care process, since the beauty instrument 100 is of appropriate size, the user can operate it more stably, making the contact between the electrode assembly 30 and the skin more continuous and stable, further improving the beauty effect.

[0050] In this embodiment, the electrode assembly 30 is exposed outside the beauty head 11, and its size and distribution are affected by the size of the housing 10. Within this size range, the electrode assembly 30 can be reasonably designed according to the area of ​​the beauty head 11. For example, it can ensure that there is a suitable spacing between the electrodes 31. When the radio frequency current is output to the skin, this spacing can make the radio frequency energy evenly distributed on the skin surface, avoiding the situation where the local energy is too high or too low.

[0051] It should be noted that the electrode assembly 30 is at least partially exposed on the beauty head 11, which may include a situation where the electrode assembly 30 is protruding from the beauty head 11, or a situation where the electrode assembly 30 is flush with the surface of the beauty head 11, or a situation where the electrode assembly 30 is recessed at a certain distance from the surface of the beauty head 11. The purpose is to enable the electrode assembly 30 to output radio frequency current to the skin during the contact between the electrode assembly 30 and the skin.

[0052] In some embodiments, the electrode assembly 30 includes a plurality of electrodes 31 , and the plurality of electrodes 31 are distributed around the central axis of the beauty head 11 .

[0053] In this embodiment, the multiple electrodes 31 are distributed around the central axis of the beauty head 11, which can make the radio frequency current more uniform when acting on the skin, helping to avoid excessive heating of the local skin or excessive energy, thereby reducing possible damage to the skin. For example, when performing radio frequency beauty care, if the electrodes 31 are unevenly distributed, some skin areas may receive too much radio frequency energy, causing skin burns, redness and swelling and other adverse reactions; however, through the multiple electrodes 31 distributed around the central axis, the radio frequency energy can be evenly transmitted to the entire skin area covered by the beauty head 11, so that the skin can receive beauty care in a gentle and balanced environment.

[0054] In some embodiments, the diameter of the electrode 31 is preferably 4 mm to 8 mm, and the distance between the electrode 31 and the central axis is preferably 8 mm to 12 mm.

[0055] In this embodiment, the diameter of the electrode 31 is 4 mm-8 mm. This size range can ensure that the electrode 31 has sufficient contact area with the skin and effectively transmits the radio frequency current to the inside of the skin. The distance between the electrode 31 and the central axis is 8 mm-12 mm, which ensures the distribution range of the electrode 31 in the beauty head 11, and enables the electrode 31 to cover a sufficient skin area around the beauty head 11. Such a distance range allows the radio frequency current to cover the skin at the edge of the beauty head 11, avoiding the situation where the skin at the edge of the beauty head 11 cannot effectively receive the radio frequency energy, thereby ensuring that the skin in the entire area covered by the beauty head 11 can be fully cared for.

[0056] Since the size of the beauty head 11 is limited, by reasonably setting the diameter of the electrode 31 and the distance from the central axis, the best layout of the electrode 31 can be achieved within the limited space of the beauty head 11. For example, if the diameter of the electrode 31 is too large or the distance from the central axis is too far, the electrodes 31 may be squeezed against each other or exceed the range of the beauty head 11, affecting the normal use of the beauty device 100.

[0057] In some embodiments, the electrode assembly 30 includes four electrodes 31 , and the four electrodes 31 are evenly distributed around the central axis of the beauty head 11 .

[0058] In this embodiment, since the distance between the electrodes 31 is relatively fixed and uniform, the output of the radio frequency current is more stable and acts on the skin more evenly, and there will be no current fluctuation or instability caused by unreasonable position of the electrodes 31.

[0059] During the beauty treatment, the four electrodes 31 work together to ensure that the radio frequency energy received by each part of the skin is roughly the same, avoiding the situation where the local energy is too high or too low, thereby reducing skin discomfort or damage caused by uneven energy. For example, when performing facial beauty care, the evenly distributed electrodes 31 can allow the forehead, cheeks, chin and other parts to receive the same degree of radio frequency stimulation, promote the uniform production of collagen, and make the skin firmness of the entire face more consistent.

[0060] In addition, the design of the four electrodes 31 can improve the efficiency of beauty treatment. Specifically, compared with a smaller number of electrodes 31, the four electrodes 31 can cover a larger skin area and output radio frequency current at the same time, which means that more skin areas can be effectively treated in the same amount of time. For example, during a beauty treatment, the four electrodes 31 can stimulate different parts of the skin at the same time, speeding up the production of collagen, thereby shortening the time required to achieve the desired beauty effect. Moreover, since the electrodes 31 are evenly distributed, the user does not need to frequently move the beauty head 11 when using the beauty instrument 100, so that more skin areas can be treated, further improving the convenience and efficiency of use.

[0061] It should be noted that the number of electrodes 31 can also be 2, 3 or more, which can be selected and set according to actual needs, and is not limited in the embodiments of the present application.

[0062] In some embodiments, please refer to Figure 3 and Figure 4 The circuit assembly 20 includes a radio frequency circuit board 21 , which is accommodated in the housing 10 and fits the inner side of the beauty head 11 .

[0063] In this embodiment, the RF circuit board 21 is arranged in contact with the inner side of the beauty head 11. This layout makes full use of the space in the housing 10, making the overall structure of the beauty instrument 100 more compact. Specifically, since the beauty instrument 100 usually needs to be portable, the compact layout can reduce the volume of the beauty instrument 100, making it easier for users to carry and use it.

[0064] At the same time, the fitting design of the beauty head 11 and the RF circuit board 21 helps to dissipate heat. Specifically, during the operation of the beauty instrument 100, the RF circuit board 21 will generate a certain amount of heat. If the heat cannot be dissipated in time, it may affect the performance and service life of the beauty instrument 100. The beauty head 11 is usually in contact with the skin and has good heat dissipation performance. The RF circuit board 21 is arranged to fit the inner side of the beauty head 11, which can quickly conduct heat to the beauty head 11 and then dissipate it through the beauty head 11, thereby ensuring the stability and reliability of the beauty instrument 100 during operation.

[0065] In some embodiments, the beauty head 11 is provided with a through hole 110 connected to the interior of the housing 10, and the electrode 31 is plugged into the RF circuit board 21 through the through hole 110. This connection method makes it very convenient to install and remove the electrode 31. If the electrode 31 fails or needs to be replaced, the user can easily unplug the electrode 31 from the RF circuit board 21 through the through hole 110 for repair or replacement.

[0066] In addition, this plug-in method is also convenient for the production and assembly of the beauty instrument 100. During the production process, workers can first install the RF circuit board 21 in the housing 10, and then insert the electrode 31 into the RF circuit board 21 through the through hole 110, thereby improving production efficiency.

[0067] Please refer to Figure 3 and Figure 5 In some embodiments, the through hole 110 includes a first hole segment 111 and a second hole segment 112, the second hole segment 112 is located between the first hole segment 111 and the interior of the housing 10, the aperture of the first hole segment 111 is larger than the aperture of the second hole segment 112, and a step 113 is formed at the connection between the first hole segment 111 and the second hole segment 112;

[0068] The electrode 31 includes a rod portion 311 and a brim portion 312 protruding from the outer periphery of the rod portion 311 . The rod portion 311 is plugged into the RF circuit board 21 through the second hole section 112 . The brim portion 312 is received in the first hole section 111 and abuts against the step 113 .

[0069] In this embodiment, by designing the through hole 110 to include a first hole section 111 and a second hole section 112, and the aperture of the first hole section 111 is larger than the aperture of the second hole section 112, the step 113 formed at the connection of this structure provides a clear positioning for the installation of the electrode 31. When the rod 311 of the electrode 31 is plugged into the RF circuit board 21 through the second hole section 112, the brim 312 protruding from the outer periphery of the rod 311 is accommodated in the first hole section 111 and abuts against the step 113, ensuring that the position of the electrode 31 on the beauty head 11 is stable and will not shake or shift during use. For example, when using the beauty instrument 100 for facial care, even if the hand shakes slightly, the electrode 31 can still maintain a stable position due to the close fit between the electrode 31 and the step 113 structure of the through hole 110, thereby ensuring that the RF current can accurately act on the skin and improve the beauty effect.

[0070] Moreover, the presence of the step 113 can prevent the electrode 31 from being over-inserted into the RF circuit board 21. Without the restriction of the step 113, the electrode 31 may damage the RF circuit board 21 or affect the normal operation of the beauty instrument 100 due to being inserted too deeply. Therefore, the step 113 in this embodiment plays a role of a mechanical limiter, ensuring that the insertion depth of the electrode 31 is just right, so that it can have good contact with the RF circuit board 21 without causing damage to the circuit board. For example, when assembling the beauty instrument 100, workers can quickly determine whether the electrode 31 is installed in place by observing the contact between the brim 312 of the electrode 31 and the step 113, thereby improving production efficiency and product quality.

[0071] In addition, the design of the brim portion 312 being accommodated in the first hole section 111 and abutting against the step 113 can also enhance the sealing performance of the beauty head 11 to a certain extent. Since the aperture of the first hole section 111 is relatively large, a certain amount of accommodation space can be provided for the brim portion 312, so that the gap between the brim portion 312 and the through hole 110 is smaller, which can reduce the possibility of dust, moisture and other impurities entering the interior of the beauty instrument 100, and protect the RF circuit board 21 and other internal components from damage. For example, in daily use, if the beauty instrument 100 accidentally contacts water or is in a humid environment, good sealing can prevent moisture from penetrating into the interior of the beauty instrument 100, reducing the risk of equipment failure due to water ingress.

[0072] In some embodiments, one of the RF circuit board 21 and the rod 311 is provided with a screw 313 , and the other is provided with a screw hole 211 , and the screw 313 is screwed into the screw hole 211 to connect the electrode 31 to the RF circuit board 21 .

[0073] In this embodiment, the connection between the RF circuit board 21 and the electrode 31 is achieved by screwing the screw 211 and the screw hole 313. This connection method can provide a very strong fixing effect, reduce the loss and interference during signal transmission, and improve the output quality and stability of the RF current. During the use of the beauty instrument 100, it may be affected by various external forces, such as shaking of the hand, slight collision, etc. This strong connection can ensure that the electrode 31 will not loosen or fall off easily, ensuring the stability and reliability of the beauty instrument 100.

[0074] When using the radio frequency beauty device 100, if the temperature of the electrode 31 is too high, it may cause burns or other injuries to the skin.

[0075] To solve this problem, in some embodiments, please refer to Figure 6 The beauty instrument 100 also includes a temperature sensor 50 for detecting the temperature of the electrode 31. The temperature sensor 50 is electrically connected to the RF circuit board 21. The RF circuit board 21 is used to receive the temperature of the electrode 31 detected by the temperature sensor 50 and adjust the power output to the electrode 31 according to the temperature of the electrode 31.

[0076] In this embodiment, the temperature sensor 50 can monitor the temperature change of the electrode 31 in time and send it to the RF circuit board 21. The RF circuit board 21 adjusts the power output to the electrode 31 according to the received data of the electrode 31, so as to avoid the electrode 31 from being too hot and ensure the safety of the beauty process. For example, when the temperature sensor 50 detects that the surface temperature of the electrode 31 is close to the critical value that may cause burns, the RF circuit board 21 will automatically reduce the power output to the electrode 31 to prevent the temperature of the electrode 31 from continuing to rise, which can effectively protect the user's skin and avoid adverse consequences caused by excessive temperature.

[0077] Since different people's skin has different sensitivity and tolerance to temperature, the presence of the temperature sensor 50 enables the beauty instrument 100 to perform personalized beauty care according to each person's specific situation. The RF circuit board 21 can adjust the output power according to the temperature data of the electrode 31 fed back by the temperature sensor 50 to adapt to the skin needs of different users. For example, for users with more sensitive skin, the RF circuit board 21 can operate at a lower temperature to reduce skin irritation; and for users with stronger skin tolerance, the output power can be appropriately increased to enhance the beauty effect. This personalized beauty care can better meet the needs of users and improve the beauty effect.

[0078] Please refer to Figure 3 and Figure 5In some embodiments, a temperature sensor 50 is provided on each electrode 31 , and the temperature sensor 50 is located in the corresponding electrode 31 , and the distance from the temperature sensor 50 to the top surface 314 of the electrode 31 is less than 1 mm.

[0079] Among them, each electrode 31 has a temperature sensor 50, and the position is inside the electrode 31, less than 1mm from the top surface 314 inside the electrode 31. This layout allows the temperature sensor 50 to be very close to the surface of the electrode 31 in contact with the skin. When the beauty instrument 100 is working, the electrode 31 contacts the skin and generates radio frequency energy, and the temperature of the electrode 31 will change. Due to heat conduction, the temperature sensor 50 inside the electrode 31 close to the surface can quickly and accurately sense this temperature change, so that the radio frequency circuit board 21 can accurately adjust the power based on the temperature information closest to the skin contact area, thereby improving the working accuracy of the entire beauty instrument 100.

[0080] In this embodiment, through the temperature sensor 50 and power adjustment, the beauty instrument 100 can maintain the temperature of the electrode 31 within a range that is conducive to promoting beauty effects, because the appropriate temperature can better stimulate the proliferation of collagen in the deep layer of the skin, reduce wrinkles, and improve skin firmness. In addition, since each electrode 31 is provided with an independent temperature sensor 50, the temperature of the electrode 31 can be monitored and fed back in real time with great accuracy, thereby preventing a single electrode 31 from overheating.

[0081] In some embodiments, the beauty instrument 100 is equipped with multiple gear settings, and different gears correspond to different power output ranges. For users with more sensitive skin, a low gear can be selected. In the low gear, after the RF circuit board 21 receives the feedback from the temperature sensor 50, it will control the power of the electrode 31 at a low level, so that the temperature increase of the electrode 31 is small, which can effectively avoid irritation or damage to sensitive skin, and gently achieve skin care effects, such as slightly promoting skin metabolism and enhancing skin barrier function. For users with better skin tolerance, a high gear can be selected. In the high gear, although the power output is high, the temperature sensor 50 continues to work. When the temperature has an overheating trend, the system can adjust the power in time to ensure that while improving the skin care effect (such as deep stimulation of collagen production, more significant skin tightening, reducing deep wrinkles, etc.), it will not cause adverse effects on the skin due to excessive temperature. This mode of working in coordination with the temperature sensor 50 fully considers the differences in skin sensitivity of different users, provides strong support for personalized skin care, and enables each user to obtain the most suitable skin care experience under the premise of safety.

[0082] In some embodiments, the circuit assembly 20 also includes a main control circuit board 22 and a battery 23. The main control circuit board 22 and the battery 23 are respectively extended along the height direction of the shell 10, and the RF circuit board 21 is extended along the width direction or length direction of the shell 10. The RF circuit board 21 is plugged into the main control circuit board 22.

[0083] In this embodiment, the main control circuit board 22 and the battery 23 are arranged to extend along the height direction of the housing 10, making full use of the longitudinal space of the housing 10 of the beauty instrument 100. Such a layout can make the beauty instrument 100 more compact in the height direction, while also leaving more lateral space for other components. For example, in some small cosmetic bags, the space in the height direction is relatively easy to use, while the lateral space may be relatively limited. This layout makes the beauty instrument 100 easier to store and carry.

[0084] The RF circuit board 21 is extended along the width direction or the length direction of the housing 10, which makes full use of the lateral space of the housing 10. Since the RF circuit board 21 usually requires a certain area to arrange circuit components, this layout can provide sufficient space for the RF circuit without increasing the overall height of the beauty instrument 100. In this way, the appearance of the beauty instrument 100 can be flatter, which is convenient for holding and operation.

[0085] In this embodiment, different circuit boards are extended in different directions to achieve clear functional division. Specifically, the main control circuit board 22 is responsible for controlling the operation of the entire beauty instrument 100, including receiving user input, processing data from the temperature sensor 50, controlling the output power of the radio frequency circuit board 21, etc. The main control circuit board 22 is arranged in the height direction to make it relatively independent from other components, which is convenient for circuit design and troubleshooting.

[0086] As an energy source, the battery 23 is arranged along the height direction to make the center of gravity more stable and convenient for connection with other circuit boards. The RF circuit board 21 is specifically responsible for generating RF current. It can be arranged along the width or length direction to make it closer to the electrode 31, reduce the loss of signal transmission, and improve the efficiency of RF output.

[0087] In this embodiment, the RF circuit board 21 and the main control circuit board 22 are connected by plug-in connection, which can ensure that the electrical connection between the two circuit boards is stable and reliable, and avoid failures caused by looseness or poor contact. In the production process, this connection method is also convenient for assembly and debugging, which can improve production efficiency. When the circuit board needs to be repaired or replaced, the plug-in connection makes it more convenient for maintenance personnel to operate. They only need to separate the two circuit boards to troubleshoot or replace damaged parts without complicated welding or disassembly work.

[0088] In some embodiments, the main control circuit board 22 is electrically connected to a charging interface 222 and a button 223, which are respectively arranged at the bottom of the housing 10, so that the user can charge the beauty instrument 100 through the charging interface 222 to ensure that the beauty instrument 100 has enough power to operate normally. The button 223 is also arranged at the bottom of the housing 10, and the user can control the working state of the beauty instrument 100 by pressing different buttons 223, such as turning on or off the beauty instrument 100, switching different working modes, etc.

[0089] In this embodiment, by setting the charging interface 222 and the button 223 at the bottom of the housing 10, on the one hand, the appearance of the beauty instrument 100 can be kept simple and integrated, avoiding the abrupt feeling that may be caused by setting the interface and button 223 at other positions; on the other hand, the bottom position is relatively hidden and not easily subject to accidental collision and damage in daily use, thereby improving the durability of the beauty instrument 100. At the same time, when using the beauty instrument 100, the user can also find and operate the charging interface 222 and button 223 at the bottom more conveniently without affecting the use experience.

[0090] In some embodiments, the peripheral side of the main control circuit board 22 is covered with a shielding cover 24, which can effectively block external electromagnetic interference, ensure the normal operation of the main control circuit board 22, and ensure that it stably and accurately issues instructions to other components such as the electrode assembly 30. At the same time, the main control circuit board 22 itself will also generate electromagnetic signals during operation. The shielding cover 24 covering the peripheral side can limit the electromagnetic signals generated by the main control circuit board 22 to the inside of the shielding cover 24 to prevent them from spreading outward, thereby avoiding the impact on other components in the beauty instrument 100 such as the temperature sensor 50 and the battery 23, ensuring the normal coordinated operation of the various components, and preventing performance degradation or failure due to electromagnetic interference.

[0091] In some embodiments, the main control circuit board 22 is provided with a wireless communication module, which is used to establish a wireless connection with the APP of the user's smart terminal. The main control circuit board 22 is used to obtain the working status of the electrode 31 through the radio frequency circuit board 21 and send it to the APP to realize the real-time transmission of the use information of the beauty instrument 100. In the process of using the beauty instrument 100, the main control circuit board 22 can send various data, such as the use time, radio frequency output power, and the temperature of the electrode 31 detected by the temperature sensor 50 to the APP, and the APP can perform personalized analysis based on these data to provide users with exclusive beauty suggestions. For example, for users with different skin types, the APP can adjust the beauty plan according to the frequency of their use of the beauty instrument 100 and the skin's reaction to radio frequency, so as to achieve better collagen growth and skin firming effects. At the same time, users can intuitively understand their use of the beauty instrument 100 each time through the APP, and better grasp the beauty progress.

[0092] In addition, by using advanced algorithms and big data analysis, the APP can accurately calculate the beauty effect based on the transmitted usage information of the beauty instrument 100. By learning and analyzing a large amount of user data, the APP can establish a relationship model between different usage parameters and beauty effects. When the user enters his or her own usage, the APP can predict the possible collagen growth and skin firmness based on this model. For example, the APP can comprehensively calculate the skin firmness improvement percentage and collagen growth amount that may be achieved within a certain period of time based on factors such as the user's continuous use of the beauty instrument 100, the adjustment of the radio frequency power, and the initial state of the skin. In this way, users can see the results of their efforts more clearly and enhance their confidence and motivation to use the beauty instrument 100.

[0093] The connection between the main control circuit board 22 and the APP not only provides practical beauty functions, but also enhances the user's sense of participation and interactivity. Users can exchange usage experience and share beauty experience with other users on the APP to form a beauty community. This interaction allows users to obtain more beauty knowledge and skills, and also increases the fun of using the beauty instrument 100.

[0094] As an implementation manner, one of the RF circuit board 21 and the main control circuit board 22 is provided with a card slot 212 , and the other is provided with a card block 221 that is engaged with the card slot 212 .

[0095] During the production and assembly process of the beauty device 100, the design of the card slot 212 and the card block 221 greatly facilitates the operation of the workers. The workers can easily align and install the RF circuit board 21 and the main control circuit board 22 together through the card slot 212 and the card block 221, which can improve production efficiency and ensure that the RF circuit board 21 and the main control circuit board 22 are closely connected to avoid poor contact or electrical failure caused by loose circuit boards.

[0096] Of course, in other implementations, the RF circuit board 21 and the main control circuit board 22 may also be connected in other ways, such as snap connection, etc., which is not limited in the embodiments of the present application.

[0097] In some embodiments, please refer to Figure 1 and Figure 2 The beauty instrument 100 further includes a cover body 40 , which is detachably connected to the beauty head 11 to cover the electrode assembly 30 .

[0098] In this embodiment, the provision of the cover 40 can effectively protect the electrode assembly 30, making the beauty instrument 100 more convenient to carry and store. When the beauty instrument 100 is not in use, or during the process of carrying or storing, the cover 40 can prevent the electrode assembly 30 from being contaminated by external collisions, scratches, dust, etc. For example, when the beauty instrument 100 is placed in a cosmetic bag and carried together with other items, the cover 40 can prevent the electrode 31 from contacting other hard objects, reduce the risk of damage to the electrode 31, help extend the service life of the electrode assembly 30, and ensure the stable performance of the beauty instrument 100.

[0099] In addition, the design of the cover 40 can add beauty and texture to the beauty instrument 100. The cover 40 of different materials, colors and shapes can match the overall design style of the beauty instrument 100 to enhance the appearance of the product.

[0100] As an embodiment, the cover body 40 and the beauty head 11 are snap-connected. This connection method is relatively strong and easy to operate, making it convenient to open and close the cover body 40. The user can easily open the cover body 40 when the beauty instrument 100 is needed, and can quickly snap it back on after use to protect the electrode assembly 30.

[0101] Of course, in other embodiments, the cover 40 and the beauty head 11 may also be detachably connected in other ways, such as magnetic attraction, etc., which is not limited in the embodiment of the present application.

[0102] In some embodiments, the cover 40 can be made of metal material, which can provide a certain shielding effect on the radio frequency of the electrode 31. Specifically, the metal material can reflect and absorb radio frequency signals. When the radio frequency signal hits the metal cover 40, an induced current will be generated on the metal surface, and this induced current will generate a reverse electromagnetic field, thereby offsetting part of the radio frequency signal, achieving a shielding effect, and preventing the beauty instrument 100 from interfering with other surrounding electronic devices when not in use.

[0103] In some embodiments, the electrode assembly 30 is also used to output a micro-current with a pulse duration of less than 30 microseconds to the skin.

[0104] In this embodiment, when the microcurrent acts on the skin, it can promote the permeability of the cell membrane, making it easier for the cells to absorb nutrients, such as moisturizing factors and repair essences in skin care products, thereby enhancing the skin's moisturizing ability and self-repair function. In addition, the microcurrent can cause slight contraction of the muscles, increase muscle firmness, and reduce skin sagging caused by muscle relaxation, especially for areas prone to sagging such as the area around the eyes and corners of the mouth.

[0105] Since the pulse duration of microcurrent is less than 30 microseconds, the energy of microcurrent is relatively low, and it will not cause burns or other serious damage to the skin under normal use, ensuring its safety and effectiveness when it works. At the same time, microcurrent with a shorter pulse duration can accurately trigger the physiological response of the skin and muscles, improving the effect of beauty and skin care.

[0106] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the embodiments here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
