[0084] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments.

In addition, ordinary technicians in this field can know that with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0085] In the description of the present application, it should be understood that, unless otherwise defined, all technical and scientific terms used in the present application have the same meaning as those commonly understood by those skilled in the art of the present application. In addition, any terminology used is only for the purpose of describing specific embodiments and is not intended to limit the present application.

[0086] In addition, in order to better illustrate the present application, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0087] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0088] In view of the defects of the above-mentioned prior art, the applicant, based on many years of rich practical experience and professional knowledge in the design and manufacture of such products, and in conjunction with the application of theory, actively conducts research and innovation, hoping to develop a technology that can solve the defects of the prior art and make the beauty instrument more practical. After continuous research and design, and after repeated trial production and improvement, the present utility model with real practical value was finally created.

[0089] Please refer to Figure 1-8 The utility model provides a multifunctional beauty instrument, which is characterized by comprising a beauty instrument body 1 (such as Figure 3 ) and two different types of beauty heads, the two different types of beauty heads are an ion beauty head 2 with a micro-current beauty function (as shown in FIG. Figure 4-5 As shown) and a water light beauty head 3 with a moisturizing and penetration beauty function (as shown Figure 6 shown);

[0090] The beauty instrument body 1 includes a first housing 101 and a circuit board 102 disposed in the first housing 101 . The first housing 101 includes a first conductive portion 103 . The first conductive portion 103 is electrically connected to the circuit board 102 .

[0091] The ion beauty head 2 and the water light beauty head 3 are respectively detachably mounted on the first housing 101; or, the water light beauty head 3 is mounted on the first housing 101, and the ion beauty head 2 covers the water light beauty head 3 and is detachably mounted on the outside of the water light beauty head 3, such as Fig.24 As shown;

[0092] The ion beauty head 2 includes a second conductive portion 202 . When the ion beauty head 2 is installed outside the first housing 101 or the water light beauty head 3 , the second conductive portion 202 is electrically connected to the circuit board 102 .

[0093] It is understandable that when Figure 4 and 5 The ion beauty head 2 shown is installed in the Figure 3 When the beauty instrument body 1 is shown, the beauty instrument that can be obtained is an ion introduction and export beauty instrument, such as Figure 1 As shown. Figure 6 The water light beauty head 3 shown is installed to Figure 3 When the beauty instrument body 1 is installed, the beauty instrument that can be obtained is a water light beauty instrument, which can also be called a water light instrument. Figure 2 shown.

[0094] It should be noted that in order to make the beauty instrument have two functions to meet two different skin care needs, realize multi-purpose of one device, reduce the cost of use, facilitate storage management and carrying, and enhance the user experience, the present embodiment improves the beauty instrument from the original non-detachable structure design to a detachable structure design, that is, the beauty instrument consists of a beauty instrument main body 1 and a beauty head detachably mounted on the beauty instrument main body 1. Since the beauty head can be removed from the beauty instrument main body 1 at any time, the beauty instrument main body 1 can be selectively plugged and connected with any one of the ion beauty head 2 and the water light beauty head 3 at any time, so that the user can choose to install the corresponding beauty head to the beauty instrument main body 1 according to different skin care needs to achieve different beauty effects.

[0095] Since the ion beauty head 2 in this embodiment needs to use microcurrent, that is, it needs to be connected to a power source, and the power source is generally arranged in the first housing 101 with sufficient space, there needs to be an electrical connection between the ion beauty head 2 and the power source located in the first housing 101. The combination of the second conductive part and the circuit board 102 constructs a path for the electrical connection between the ion beauty head 2 and the power source located in the first housing 101, so that when the ion beauty head 2 is installed on the outside of the first housing 101 or the water light beauty head 3, the second conductive part 202 is connected to the circuit board 102, and the power source can supply electric energy to the ion beauty head 2. It can be understood that the power source may not be directly arranged in the first housing 101, and the ion beauty head 2 is electrically connected to the external power source by electrically connecting the circuit board 102 in the first housing 101, and the external power source provides power to the ion beauty head 2.

[0096] With respect to the first setting mentioned above, that is, the two beauty heads, the ion beauty head 2 and the water light beauty head 3, are detachably mounted on the first shell 101, respectively, the volume of the product can be reduced, making the entire beauty instrument compact and light, and convenient for storage, management and carrying; with respect to the second setting mentioned above, that is, the water light beauty head 3 is mounted on the first shell 101, and the ion beauty head 2 covers the water light beauty head and is detachably mounted on the outside of the water light beauty head, the integrity of the beauty instrument can be improved, making the entire beauty instrument more coordinated and unified in appearance and use, and more convenient to carry and store.

[0097] In the second setting, on the one hand, the water light beauty head 3 can be detachably mounted on the first housing 101, and on the other hand, the water light beauty head 3 can also be non-detachably mounted on the first housing 101. For the ion beauty head 2, whether the water light beauty head 3 is detachably mounted on the first housing 101 does not affect its operation, because even if the water light beauty head 3 is non-detachably mounted on the first housing 101, it is only necessary to ensure that the second conductive part 202 of the ion beauty head 2 can be electrically connected to the circuit board 102 when the ion beauty head 2 covers the water light beauty head 3 and is detachably mounted on the outside of the water light beauty head 3.

[0098] It is understandable that the circuit board 102 can be a whole board or a small board, depending on the design and functional requirements of the beauty instrument. A whole board may contain more circuit elements and a more complex circuit design, while a small board may be more concise and focused on a specific function. Whether it is a whole board or a small board, they play a vital role to ensure the stable operation and function realization of the beauty instrument.

[0099] Optionally, a sensor for sensing the human body may be provided on the ion beauty head 2. When the ion beauty head 2 contacts the human skin, the sensor senses the human body, and the circuit board 102 is able to control the power supply to supply electrical energy to the ion beauty head 2, thereby avoiding the ion beauty head 2 from doing ineffective work, that is, avoiding the ion beauty head 2 from still outputting microcurrent when the user forgets to turn off or accidentally turns on the beauty instrument, thereby saving energy consumption and improving the intelligence of the beauty instrument.

[0100] The sensor may be selected from but not limited to infrared sensors, temperature sensors, and distance sensors. The sensor detects the human epidermis or the distance between the product and the human body. When the human epidermis cannot be detected or the detection distance does not meet the conditions, the circuit board 102 controls the power supply to stop supplying power to the ion beauty head 2. When the human epidermis is detected or the detection distance meets the conditions, the circuit board 102 controls the power supply to supply power to the ion beauty head 2.

[0101] It is understandable that the specific function of other structural designs in the beauty instrument body 1, such as the charging device, indicator light, etc., is to ensure the normal operation of various functions of the beauty instrument body 1. In view of the fact that these structural designs have been implemented in many existing technologies and are not the focus of the design of this solution, they will not be elaborated in depth here.

[0102] Please refer again Figure 4-5 In this embodiment, further, the ion beauty head 2 includes a second shell 201 , the second shell 201 is installed outside the first shell 101 or the water light beauty head 3 , and the second conductive part 202 is arranged in the second shell 201 .

[0103] Please refer again Figure 7 In a first embodiment, the first conductive portion 103 may be a conductive member disposed on the surface of the first housing 101;

[0104] Please refer again Figure 8 In the second embodiment, part or all of the first housing 101 may be made of a conductive material to form the first conductive portion 103;

[0105] It should be noted that, regardless of the first embodiment or the second embodiment, the purpose of their design is to achieve that the first shell 101 is connected to the human body after contacting the skin of the human hand, so that the ion beauty head 2 can form a current loop after contacting the human face skin, thereby ensuring the realization of the ion import and export functions.

[0106] It should be noted that, when in use, the first conductive part 103 and the second conductive part 202 form a closed loop through the human body, and the user selects the ion beauty working mode of the beauty instrument to achieve the introduction of beauty ingredients or the export of skin dirt, thereby improving the skin condition. In this way, a single ion beauty head can meet two different beauty needs, improve the convenience of product use, and thus enhance the user experience. It is understandable that the ion beauty head can be set to have only a single import function or export function. In this case, it is only necessary to set the first conductive part 103 and the second conductive part 202 to a single polarity.

[0107] The principle of ion introduction is as follows: after the ion introduction mode is turned on, the second conductive part 202 of the ion beauty head 2 is the positive electrode, and the first conductive part 103 of the beauty instrument body 1 is the negative electrode. When the user holds the beauty instrument body 1 and contacts the first conductive part 103, and the second conductive part 202 contacts the skin, the human body, the first conductive part 103, the circuit board 102 and the second conductive part 202 form a current loop, and the microcurrent flows out from the circuit board 102, is transmitted to the second conductive part 202, and returns to the circuit board 102 from the first conductive part 103 after passing through the human body. Under the influence of the electric field, the positively charged active ingredients in the nutritional essence applied on the skin are repelled by the second conductive part 202 of the same polarity, move to the skin, and penetrate deep into the skin, thereby achieving the purpose of promoting the absorption of the nutritional essence, and then achieving the effect of beauty and skin care.

[0108] Principle of ion export (same as ion introduction): After the ion export mode is turned on, the first conductive part 103 of the beauty instrument body 1 is the positive pole, and the second conductive part 202 is the negative pole. When the user holds the beauty instrument body 1 and touches the first conductive part 103, and the second conductive part 202 touches the skin, the human body, the first conductive part 103, the circuit board 102 and the second conductive part 202 form a current loop, and the microcurrent flows out from the circuit board 102, is transmitted to the first conductive part 103, passes through the human body, and returns to the circuit board 102 from the second conductive part 202. Dirt with negative ions in human skin is repelled by human skin of the same polarity under the influence of the electric field and discharged from the skin, thereby achieving the effect of sewage removal and cleaning.

[0109] It should be noted that in actual applications, the selection and use of the conductive part or conductive material needs to take into account factors such as safety, conductivity, and durability to ensure the stability and safety of the beauty instrument. In addition, the design of the conductive part or conductive material also needs to be coordinated with the overall design and functional requirements of the beauty instrument to achieve the best user experience and effect.

[0110] In this embodiment, the specific forms of the first conductive portion 103 and the second conductive portion 202 are further refined.

[0111] On the one hand, the first conductive part 103 can be in the form of a conductive electrode sheet, that is, the conductive member disposed on the surface of the first housing 101 is a conductive electrode sheet, and the second conductive part 202 can also be in the form of a conductive electrode sheet;

[0112] It should be noted that the conductive electrode sheet usually has high conductivity and stability, and can ensure stable and reliable current transmission between the beauty instrument body 1 and the ion beauty head 2.

[0113] On the other hand, the first conductive part 103 may be in the form of a conductive film, that is, the conductive member disposed on the surface of the first housing 101 is a conductive film, and the second conductive part 202 is still in the form of a conductive electrode sheet.

[0114] It should be noted that the conductive film, such as a water-plated film, has good conductivity and flexibility, and can cover the entire surface or a part of the first housing 101, thereby increasing the conductive area and conductive performance of the beauty instrument. The second conductive part 202 is in the form of a conductive electrode sheet, which can ensure a stable connection with the first conductive part 103.

[0115] It should be noted that the selection of conductive film and conductive electrode sheet should be determined according to the specific application scenario and requirements. Conductive film may be more suitable for situations that require large-area conductivity or flexible conductivity, while conductive electrode sheet may be more suitable for situations that require high conductivity and stability. At the same time, the specific shape, size and layout of the conductive film and conductive electrode sheet should also be designed and optimized according to the overall design and functional requirements of the beauty instrument.

[0116] In this embodiment, the first housing 101 further includes a contact terminal 6 electrically connected to the circuit board 102. Figure 3 As shown, the ion beauty head 2 also includes a connection terminal 5 electrically connected to the second conductive part 202, such as Figure 5 As shown, the second conductive part 202 is electrically connected to the circuit board 102 through the connecting terminal 5 and the contact terminal 6;

[0117] Alternatively, the water light beauty head 3 further includes a contact terminal 6 electrically connected to the circuit board 102 , and the ion beauty head 2 further includes a connection terminal 5 electrically connected to the second conductive part 202 , and the second conductive part 202 is electrically connected to the circuit board 102 via the connection terminal 5 and the contact terminal 6 .

[0118] It should be noted that, since the ion beauty head 2 is detachably connected to the first shell 101 or the outer side of the water light beauty head 3, if it is to be ensured that the second conductive part 202 of the ion beauty head 2 can be stably and effectively electrically connected to the circuit board 102, it is necessary to provide a connection terminal 5 and a contact terminal 6 that can be conductive after contacting each other.

[0119] In this embodiment, the structure of the first housing 101 is further designed in view of the fact that the ion beauty head 2 and the water light beauty head 3 are detachably installed in the first housing 101. Specifically, the first housing 101 includes a special installation position 4, such as Figure 3 As shown, the design of the mounting position 4 enables the ion beauty head 2 and the water light beauty head 3 to be detachably mounted thereon. This design not only improves the modularity of the beauty instrument, allowing users to flexibly replace the beauty heads according to their needs, but also ensures the stability of the installation and the convenience of use.

[0120] Through such a design, users can easily replace the ion beauty head 2 or the water light beauty head 3 according to their personal skin care needs to achieve different skin care effects. At the same time, due to the standardized design of the installation position 4, the replacement process of the beauty head is simple and fast, without complicated operations, further improving the user experience.

[0121] In this embodiment, the design of the mounting position 4 is further refined. Specifically, a mounting groove 12 is provided on the mounting position 4. Figure 3 As shown, the design of the mounting groove 12 is to ensure that the ion beauty head 2 and the water light beauty head 3 can be smoothly installed and tightly combined with the mounting position 4. The shape of the mounting groove 12 matches the shape of the ion beauty head 2 and the water light beauty head 3, so that the stability and accuracy of the installation can be guaranteed.

[0122] In addition, another design scheme is considered, that is, the ion beauty head 2 and the water light beauty head 3 are respectively provided with mounting grooves 12, and the mounting position 4 is designed to be a shape matching these mounting grooves 12. In this design scheme, the mounting position 4 can be smoothly installed in the mounting groove 12 of the ion beauty head 2 or the water light beauty head 3, and a tight and stable installation effect can also be achieved.

[0123] Both of these design solutions can effectively improve the modularity and ease of use of the beauty instrument. The user can select a suitable beauty head according to the needs and conveniently install it on the beauty instrument. At the same time, due to the matching design of the shape of the installation slot 12 and the beauty head, the installation process is simpler and faster, which improves the user experience.

[0124] It is understood that, in addition to the above-mentioned snap-on connection, there are multiple options for connecting the ion beauty head 2 and the water light beauty head 3 with the first housing 101. Among them, threaded connection and magnetic connection are both common and practical connection methods. It is understood that two connection methods can also be used at the same time, for example, a magnetic method can be added on the basis of the snap-on connection to further ensure the connection reliability between the beauty head and the first housing 101.

[0125] For the threaded connection, the bottom or side of the ion beauty head 2 and the water light beauty head 3 can be designed with threads (such as external threads), and the mounting position 4 on the first shell 101 is also correspondingly designed with threads (such as internal threads). By rotating the ion beauty head 2 or the water light beauty head 3, they can be tightly connected to the first shell 101. This connection method has high stability and durability, and can ensure that it is not easy to loosen or fall off during use.

[0126] For magnetic connection, magnets can be embedded in the bottom of the ion beauty head 2 and the water light beauty head 3, and the mounting position 4 of the first shell 101 is provided with magnetic material or made of magnetic material. When the ion beauty head 2 or the water light beauty head 3 is close to the mounting position 4, they will automatically be attracted together due to the attraction of magnetic force, achieving a fast and stable connection. This connection method is easy to operate and has a good user experience, and is especially suitable for users who pursue speed and convenience.

[0127] In this embodiment, in order to ensure a stable connection between the ion beauty head 2 and the first housing 101 and to ensure the accuracy and reliability of the circuit connection, the mounting position 4 further has a first bonding surface 13 in contact with the ion beauty head 2, such as Figure 3 As shown, the first joint surface 13 will fit closely with the ion beauty head 2 when it is installed, ensuring the stability of the installation and the reliability of the contact. At the same time, the contact terminal 6 is cleverly designed on the first joint surface 13, so that when the ion beauty head 2 is installed in place, the connection terminal 5 inside it can directly contact the contact terminal 6 to achieve circuit connection.

[0128] Correspondingly, the ion beauty head 2 also has a second bonding surface 14 in contact with the first bonding surface 13. Figure 5 The second joint surface 14 matches the first joint surface 13 in shape and size to ensure that the two can fit tightly. The connecting terminal 5 is located on the second joint surface 14. When the ion beauty head 2 is installed in the installation position 4, the connecting terminal 5 can be accurately connected with the contact terminal 6 to achieve the transmission of electrical signals.

[0129] In addition, the surface of the ion beauty head 2 connected to the first housing 101 can be designed to be flush with the surface of the first housing 101, so that the ion beauty head 2 and the surface of the first housing 101 are integrated and more beautiful. The water light beauty head 3 has the same design.

[0130] Please refer again Figure 8 This embodiment further refines the specific structural design style of the first shell 101.

[0131] The first housing 101 is divided into three main parts: a beauty head connecting part 1011, a middle part 1012 and a hand-held part 1013. These three parts are sequentially connected together by a certain connection method (such as integral molding, screw fixing, etc.), forming the basic frame of the beauty instrument body 1.

[0132] The beauty head connecting part 1011 is a key part for connecting the beauty instrument body 1 and the beauty head, and its structural design should ensure that the beauty head can be firmly installed on the beauty instrument body 1.

[0133] The middle part 1012 is located between the beauty head connection part 1011 and the handheld part 1013. It adopts a concave curved surface design, which not only makes the appearance of the beauty instrument more elegant and beautiful, but more importantly, it provides a natural hand-holding position for the user. When the user holds the handheld part, the concave curved surface can perfectly fit the user's fingers, providing the user with a more comfortable and stable holding experience. It is understandable that multiple concave curved surfaces can be set around the middle part 1012 to be suitable for cooperating with a variety of holding gestures to meet the different holding habits of different users. At the same time, the middle part 1012 also plays the role of a bridge, tightly connecting the beauty head connection part 1011 and the handheld part 1013 together to ensure the stability and durability of the overall structure.

[0134] The hand-held portion 1013 is the portion that the user directly holds, and forms an angle with the beauty head connecting portion 1011. Optionally, the angle is set to be less than 180 degrees. Its design should take into account factors such as comfort, anti-slip and portability. At the same time, this portion can also serve as a support and fixing structure for internal components such as the circuit board 102.

[0135] It should be noted that the beauty head connection part 1011 and the second shell 201, or the beauty head connection part 1011 (equivalent to a fixed part) and the third shell 301 (equivalent to a movable part) can be combined to form a beauty care part, which may include a beauty care functional component for skin care, and optionally, the beauty care functional component can be arranged in the second shell 201 or the third shell 301. It is understandable that the beauty care part can be designed as a structure in which the beauty head connection part 1011 and the second shell 201 (or the third shell 301) are fixedly installed, or can be designed as a structure in which the beauty head connection part 1011 and the second shell 201 (or the third shell 301) can be detachably installed from each other.

[0136] Exemplarily, the beauty care functional component can be at least one of a microneedle device, a spray device (or mist device), a photoelectric care device, an ultrasonic care device, and a massage care device. For example, when the beauty care functional component is an electric care device, the beauty instrument can become an ion (or microcurrent, radio frequency) beauty instrument; when the beauty care functional component is a microneedle device and a spray device, the beauty instrument can become a water light beauty instrument.

[0137] In this embodiment, whether the first housing 101 is entirely or partially made of a conductive material will be described in more detail in this embodiment.

[0138] When the entire first housing 101 is made of conductive material, it means that the beauty head connecting part 1011, the middle part 1012 and the hand-held part 1013 will all be made of conductive material. This design can ensure that the entire beauty instrument body 1 is conductive, so that it can be connected to the human body after contacting the human hand skin at any position. In addition, the design of all conductive materials can also improve the beauty and overall sense of the beauty instrument, making it look more high-end and fashionable.

[0139] However, the design of all conductive materials may increase the cost and manufacturing difficulty. Therefore, in actual production, it may be considered to design only part of the first shell 101 as a conductive material. In this case, there may be a variety of combinations. For example, both the middle part 1012 and the handheld part 1013 can be made of conductive materials, while the beauty head connecting part 1011 is made of non-conductive materials. Alternatively, only the middle part 1012 is made of conductive material, and the handheld part 1013 and the beauty head connecting part 1011 are made of non-conductive materials. Alternatively, only the handheld part 1013 is made of conductive material, while the middle part 1012 and the beauty head connecting part 1011 are made of non-conductive materials.

[0140] This partially conductive material design can reduce costs and manufacturing difficulty while maintaining a certain level of conductivity.

[0141] It should be noted that whether you choose a design with fully conductive materials or partially conductive materials, you need to consider factors such as safety, conductivity, and durability. The selection and use of conductive materials should ensure the stability and safety of the beauty instrument.

[0142] In addition, the specific structural design style of the first shell 101 can also be designed in a more diversified manner according to factors such as product positioning, user groups and market demand to meet the usage habits and aesthetic needs of different users.

[0143] Please refer again Figure 6 In this embodiment, further, the water light beauty head 3 includes a third shell 301, and the third shell 301 is installed in the first shell 101;

[0144] The water light beauty head 3 also includes a micro-needle device 302 and / or a mist outlet device;

[0145] The microneedle device 302 and / or the mist outlet device are disposed at an end of the third housing 301 away from the first housing 101 .

[0146] Furthermore, the water light beauty head 3 is also provided with an atomization outlet 303 opened in the third shell 301, which is used to discharge the mist generated by the mist outlet device. The microneedle device 302 is provided with a mist outlet 312 corresponding to and connected to the atomization outlet 303; and / or, the atomization outlet 303 is arranged near the microneedle device 302. Specifically, the atomization outlet 303 can be designed to surround the microneedle device 302 to be close to the microneedle device 302; or, as Figure 6 and Fig. 9 As shown, the microneedle device 302 is provided with at least one through avoidance hole, and this avoidance hole can also be used as the above-mentioned mist outlet 312. Of course, the atomization outlet 303 can also be arranged side by side and close to the microneedle device 302. It can be understood that the atomization outlet 303 can be set only at a position close to the microneedle device 302, or the atomization outlet 303 can be opened only at the position of the third shell 301 corresponding to the microneedle device 302, and then the microneedle device 302 correspondingly opens a mist outlet 312 connected to the atomization outlet 303.

[0147] It should be noted that when the ion beauty head 2 is installed on the beauty instrument body 1, the combination of the first shell 101 and the second shell 201 is the entire shell of the beauty instrument; similarly, when the water light beauty head 3 is installed on the beauty instrument body 1, the combination of the first shell 101 and the third shell 30 is the entire shell of the beauty instrument.

[0148] The microneedle device 302 may include a microneedle wafer or other forms of microneedles. The microneedle wafer technology is a high-tech medical cosmetic technology. The microneedle wafer is also called "nano-microneedle" or "wafer microneedle". It is made of biocompatible nanoporous silicon material. The needle tip diameter is less than 100 nanometers and only penetrates the stratum corneum of the skin, so it is relatively safe. The water light beauty head 3 can use the microneedle wafer to stimulate the skin and form a fine skin channel on the skin surface so that nutrients or drugs (collectively referred to as essence) can penetrate into the skin to achieve a cosmetic effect.

[0149] Since mist essence can be better and more evenly distributed on the skin than liquid essence, and is easier to penetrate into the skin and be absorbed by the skin to bring moisture and soothing to the skin, the essence in the water light beauty head 3 needs to be atomized before contacting the skin, and the setting of the mist outlet device is convenient for achieving this purpose.

[0150] It is understandable that when only the microneedle device 302 or the mist outlet device is set in the water light beauty head 3, the beauty instrument can independently perform microneedle penetration care or atomization supply care. When only a single function care is desired, the use experience and care effect will not be reduced due to the mutual influence between the components for realizing different care functions. Although the microneedle device 302 and the mist outlet device can be set separately, in order to achieve better skin care effects, the water light beauty head 3 can be provided with a microneedle device 302 and a mist outlet device at the same time. The mist outlet device is used in combination with the microneedle device 302, that is, while the microneedle device 302 is used to open a deep channel for the skin, atomized essence can be provided through the mist outlet device, so that the essence can penetrate the skin through the skin channel opened by the microneedle device 302 at the first time, thereby improving the care efficiency and the care effect. In addition, if the third shell 301 is detachably mounted on the first shell 101, the water light beauty head 3 can be designed as a disposable product, and the user can replenish the essence or replace the microneedle device by replacing the water light beauty head, thereby improving the convenience of user care and beauty, and also improving hygiene and safety. If the third housing 301 is non-detachably mounted on the first housing 101, a structure for easily replenishing the essence can be designed on the third housing 301. For example, a liquid replenishing port can be provided, through which the user can directly add essence to the water light beauty head 3 without removing the water light beauty head 3 from the first housing 101.

[0151] Please refer again Figure 7-8 In this embodiment, further, the beauty instrument body 1 further includes an air supply mechanism 8 disposed in the first shell 101;

[0152] The gas supply mechanism 8 is electrically connected to the circuit board 102 , and the gas supply mechanism 8 is connected to the water light beauty head 3 for delivering gas to the mist outlet device.

[0153] It should be noted that the air supply mechanism 8 plays a vital role in the implementation of pneumatic atomization. When negative pressure aspiration atomization is adopted, the flow path of the gas provided by the air supply mechanism 8 is isolated from the flow path of the essence liquid, and the purpose is to use high-speed gas to generate negative pressure at the outlet of the flow path of the essence liquid, so that the essence liquid can be sucked out of the flow path, and by combining with the essence liquid, the essence liquid is turned into small molecule aerosol, thereby realizing the atomization of the essence liquid.

[0154] When high-pressure air atomization is adopted, the flow path of the gas provided by the air supply mechanism 8 is connected with the flow path of the essence, and at the end, the gas and the essence will share a flow path, aiming to realize the atomization of the essence by utilizing high-speed gas to spray the essence in the same flow path into tiny droplets.

[0155] Since the droplets produced by negative pressure suction atomization are usually smaller and evenly distributed, they can better cover the human facial skin, while the droplets produced by high-pressure blowing atomization may be larger in size and the distribution may also be affected by the airflow, which is not as uniform as negative pressure suction atomization. Therefore, this embodiment prefers negative pressure suction atomization as the atomization method.

[0156] It is understandable that when setting the air supply mechanism 8, it is taken into consideration that if the air supply mechanism 8 is set in the hyaluronic acid beauty head 3, the structure of the hyaluronic acid beauty head 3 will be very complicated and the volume will be large, the design difficulty will increase, and the reliability will be reduced. At the same time, when the hyaluronic acid beauty head 3 is damaged after long-term use and needs to be replaced, or when the hyaluronic acid beauty head 3 needs to be designed as a disposable product, the disposal cost of the hyaluronic acid beauty head 3 composed of too many parts will be very high. Therefore, this embodiment chooses to set the air supply mechanism 8 in the beauty instrument body 1 to maximize the utilization of the air supply mechanism 8, so as to reduce the structural complexity of the hyaluronic acid beauty head 3 and reduce the disposal cost.

[0157] Exemplarily, the air supply mechanism 8 may be an air pump.

[0158] Please refer to Figure 9-11 In this embodiment, further, the mist outlet device includes a gas flow channel 304 and a liquid flow channel 305 provided in the third shell 301;

[0159] A liquid outlet 306 is provided at one end of the liquid flow channel 305;

[0160] An air inlet 307 is disposed at one end of the gas flow channel 304, and an air outlet 308 is disposed at the other end of the gas flow channel 304. The air inlet 307 is connected to the gas supply mechanism 8, and the air outlet 308 is disposed near the liquid outlet 306. For example, the air outlet 308 is disposed around part or all of the liquid outlet 306. Fig.10 As shown, the air outlet 308 is annular and is arranged around the liquid outlet 306; or, the air outlet 308 includes one or more and is arranged on the side around the liquid outlet 306, or, the air outlet 308 and the liquid outlet 306 are arranged side by side, or, the liquid outlet 306 is arranged around part or all of the air outlet 308, or, the liquid outlet 308 includes one or more and is arranged on the side around the air outlet 308.

[0161] It should be noted that, in this embodiment, the third shell 301 is provided with an atomizing bin 321, and the mist outlet device may also be referred to as an atomizing mechanism or a liquid outlet mechanism, which includes an atomizing bin 321 arranged on the third shell 301. The first design of the atomizing bin 321 in this embodiment is that the atomizing bin 321 includes a main body 322, and the main body 322 is provided with an air inlet 307, an air outlet 308, a liquid outlet 306, a gas flow channel 304 and a liquid flow channel 305. The main body 322 is a medium delivery pipeline. The second design is that the atomization chamber 321 can also include an atomization nozzle 323 interconnected with the main body 322, the liquid outlet 306 and the gas outlet 308 are arranged at the atomization nozzle 323, the main body 322 is provided with a gas flow channel 304 and a liquid flow channel 305, the liquid outlet 306 is connected to the liquid flow channel 305, and the gas outlet 308 is connected to the gas flow channel 304. It can be understood that when the atomization nozzle 323 and the main body 322 in the second design of the atomization chamber 321 of this embodiment are designed as an integrated whole, it is the first design of the atomization chamber 321 of this embodiment.

[0162] In addition, it should be noted that the third shell 301 and the mist outlet device are at least part of the essence bottle, and the third shell 301 is equivalent to the bottle body of the essence bottle. The mist outlet device and the third shell 301 can be combined to form an atomization device, and the air supply mechanism 8, the mist outlet device and the third shell 301 can be combined to form a pneumatic atomization device.

[0163] The air inlet 307 of the gas flow channel 304 is connected to the air supply mechanism 8. The gas provided by the air supply mechanism 8 enters the gas flow channel 304 from the air inlet 307 of the gas flow channel 304, and then flows out from the air outlet 308 of the gas flow channel 304, so that negative pressure is formed at the liquid outlet 306. At this time, the essence in the liquid flow channel 305 can flow out from the liquid outlet 306 under the action of the negative pressure, and after combining with the gas, it becomes a small molecule mist and is sprayed to reach the human face.

[0164] It is understandable that the atomized essence can be introduced into the dermis, opening millions of channels in the epidermis of several square millimeters without damaging the epidermis of the skin, allowing the active ingredients of the essence to effectively penetrate the skin, stimulate collagen proliferation and cell regeneration, and repair aging cells. After the essence is fully atomized, it can ensure the uniformity of the nutrient solution penetrating into the skin, avoid the waste of essence, and improve the beauty and skin care effect.

[0165] In the design of the beauty instrument, the positional relationship between the air outlet 308 and the liquid outlet 306 is an important factor affecting the atomization effect of the essence. The air outlet 308 is arranged around part or all of the liquid outlet 306, or a plurality of air outlets 308 are arranged along the circumference of the liquid outlet 306, so that a uniform and soft atomization effect can be achieved. The air outlet 308 and the liquid outlet 306 are arranged side by side, and because the air outlet is relatively concentrated, under the same output power of the air supply mechanism 8, the gas flow rate is faster than that of the annularly arranged air outlet 308, so the atomization speed can be increased. The liquid outlet 306 is arranged around part or all of the air outlet 308, or a plurality of liquid outlets 306 are arranged along the circumference of the air outlet 308, so that the atomization area and the atomization flow rate can be expanded as much as possible while ensuring a high atomization speed.

[0166] Specifically, when the gas outlet 308 is arranged around part or all of the liquid outlet 306, or when multiple gas outlets 308 are arranged along the peripheral side of the liquid outlet 306, the gas surrounds the essence, forming a "gas surround" effect, so that the essence is more evenly wrapped and atomized by the gas. This method can ensure that the essence is fully atomized, thereby improving its permeability and utilization rate. At the same time, due to the effect of gas surround, the atomization process of the essence is gentler and less irritating to the skin.

[0167] When the gas outlet 308 and the liquid outlet 306 are arranged side by side, this positional relationship can make the mixing of the essence and the gas more direct and rapid, thereby increasing the speed of atomization.

[0168] When the liquid outlet 306 is arranged around part or all of the gas outlet 308, or multiple gas outlets 308 are arranged along the periphery of the liquid outlet 306, the essence can flow to the gas outlet 308 from multiple directions, increasing the outflow of the essence per unit time and the contact area between the essence and the gas. Such a design can not only ensure that more essence flows out and is fully atomized, but also achieve a uniform atomization effect over a wider area.

[0169] In the actual production process, the appropriate layout can be selected according to specific needs and product characteristics to achieve the best atomization effect.

[0170] In this embodiment, further, the distance between the liquid outlet 306 and the gas outlet 308, and / or the range of their area ratio needs to meet certain misting conditions, which affects the misting effect. By reasonably designing these two parameters, it can be ensured that the misting device can produce a uniform and delicate atomization effect, thereby improving the skin care effect and user experience.

[0171] Optionally, the distance between the liquid outlet 306 and the gas outlet 308 can be set within a range. For example, the distance between the liquid outlet 306 and the gas outlet 308 can be 0.01mm, 0.25mm or 0.5mm. Optionally, the distance range between the liquid outlet 306 and the gas outlet 308 can be set based on the required mist output. For example, when the required mist output is large, the distance between the liquid outlet 306 and the gas outlet 308 can be set to 0.01mm; when the required mist output is medium, the distance between the liquid outlet 306 and the gas outlet 308 can be set to 0.25mm; when the required mist output is small, the distance between the liquid outlet 306 and the gas outlet 308 can be set to 0.5mm.

[0172] It should be noted that this spacing determines the contact mode and speed of the essence and gas. If the spacing is too large, the essence and gas may not be able to fully contact and mix, resulting in poor atomization effect; if the spacing is too small, the essence may mix with the gas too quickly, also affecting the atomization effect. Therefore, this spacing range is to ensure that the essence and gas can mix at an appropriate speed and distance, thereby achieving efficient atomization.

[0173] The mist discharge condition that needs to be satisfied by the area ratio of the liquid outlet 306 to the gas outlet 308 is that the area ratio of the liquid outlet 306 to the gas outlet 308 is in the range of 0.2-0.7.

[0174] It should be noted that this area ratio range means that the ratio of the area of ​​the liquid outlet 306 to the area of ​​the gas outlet 308 should be maintained within this ratio range. This ratio determines the degree of mixing of the essence and the gas. For example, the area ratio of the liquid outlet 306 to the gas outlet 308 can be set to 0.2, 0.45 or 0.70. Optionally, the area ratio of the liquid outlet 306 to the gas outlet 308 can be set based on the required mist output. For example, when the required mist output is small, the area ratio of the liquid outlet 306 to the gas outlet 308 can be set to 0.2; when the required mist output is medium, the area ratio of the liquid outlet 306 to the gas outlet 308 can be set to 0.45; when the required mist output is large, the area ratio of the liquid outlet 306 to the gas outlet 308 can be set to 0.70. If the area ratio is too small (for example, less than 0.2), the essence of the liquid outlet 306 may be less, resulting in a small amount of mist output; if the area ratio is too large (for example, greater than 0.7), the essence of the liquid outlet 306 may be more, which may result in excessive mist output and waste, or even cause the essence to fail to be fully atomized and produce droplets. Therefore, this ratio range is to ensure that the essence and gas can be evenly and fully mixed, so as to produce an ideal atomization effect.

[0175] Please refer again Fig. 9 and 25In the present embodiment, further, for the design of an atomizing nozzle 323, the atomizing nozzle 323 may include a liquid outlet part 318 and a socket part 319, the socket part 319 is sleeved on the outer peripheral side of the liquid outlet part 318, the liquid outlet port 306 penetrates the liquid outlet part 318, an air outlet cavity 320 is arranged between the socket part 319 and the liquid outlet part 318, the air outlet cavity 320 is connected to the gas flow channel 304, and the air outlet 308 is formed at one end of the air outlet cavity 320 away from the gas flow channel 304.

[0176] It should be noted that the design of the air outlet cavity 323 is more conducive to uniform airflow at the air outlet 308 .

[0177] In this embodiment, the design of the beauty instrument is further expanded and improved.

[0178] Regarding the design of the liquid storage structure, please refer to Figure 9-11 , and combined with reference Fig. 22 In the first embodiment, a liquid storage chamber 309 is further provided in the third housing 301, which may also be referred to as a liquid storage chamber. The liquid storage chamber 309 is used to store the essence;

[0179] The other end of the liquid flow channel 305 is provided with a liquid inlet 310, and the liquid inlet 310 is connected to the liquid storage chamber 309. Fig. 22 shown.

[0180] It should be noted that, in this embodiment, by setting a liquid storage chamber 309 in the third shell 301, a certain storage space can be provided for the essence, thereby increasing the storage capacity of the essence in the water light beauty head 3, thereby increasing the use time of the water light beauty head 3 and reducing the frequency of changing the beauty head or replenishing the liquid.

[0181] In addition, the liquid storage chamber 309 and the third shell 301 are of an integral design and cannot be disassembled, which improves the integrity of the structure, avoids errors caused by human assembly, and reduces the risk of leakage.

[0182] It is understandable that if the water light beauty head 3 is designed for liquid replenishment, in order to facilitate the replenishment of essence liquid in the liquid storage chamber 309, a liquid replenishment port connected to the liquid storage chamber 309 is also opened on the third shell 301.

[0183] Please refer again Figure 8-9 , in this embodiment, further, the gas flow channel 304 surrounds part or all of the liquid flow channel 305;

[0184] The liquid storage chamber 309 surrounds part or all of the liquid flow channel 305 .

[0185] It should be noted that, in order to increase the reliability of use and ensure the atomization effect, the gas flow channel 304 needs to ensure the gas output volume and gas output speed, and the gas flow channel 304 needs to be arranged around the liquid flow channel 305. On the one hand, it can surround part of the liquid flow channel 305, and on the other hand, it can also surround the entire liquid flow channel 305. Fig.23 As shown, this design can increase the cross-sectional area of ​​the gas flow channel 304 and increase the total ventilation volume, which can increase the flow rate at the gas outlet 308, increase the negative pressure of the environment near the gas outlet 308, and ensure the atomization effect.

[0186] Fig. 9 The figure shows the case where the gas flow channel 304 surrounds part of the liquid flow channel 305. In this case, one gas flow channel 304 may be arranged to surround part of the liquid flow channel 305, or at least two gas flow channels 304 may be arranged to surround part of the liquid flow channel 305. The number and shape of the gas flow channels 304 may be specifically set according to actual needs. Fig. 9 In the embodiment, the number of gas flow channels 304 is set to two, and the shape is crescent-shaped and symmetrically arranged. Figure 10-11 In the embodiment, the number of the air outlet 308 and the air inlet 307 are also set to two symmetrical ones, and the shapes are crescent-shaped.

[0187] It should be noted that, in order to increase the storage capacity of the essence and ensure that it can be used for a longer period of time, on the one hand, the liquid storage cavity 309 can surround part of the liquid flow channel 305, and on the other hand, the liquid storage cavity 309 can surround the entire liquid flow channel 305. The liquid storage cavity 309 surrounding the entire liquid flow channel 305 can obtain a larger liquid storage space.

[0188] Of course, the location of the liquid storage chamber 309 is not limited to the third housing 301. In fact, it is also a feasible option to set it in the first housing 101. By setting the liquid storage chamber 309 in the first housing 101, the following two advantages can be achieved:

[0189] First, the first housing 101 usually has a relatively large internal space, which provides sufficient space for the design of the liquid storage chamber 309. By arranging the liquid storage chamber 309 here, this space can be fully utilized to maximize the storage capacity, thereby ensuring long-term use without frequent replenishment of essence.

[0190] Secondly, from the perspective of maintenance and replenishment of essence, it may be more convenient to arrange the liquid storage chamber 309 in the first housing 101. The user may more easily access and operate the liquid storage chamber 309 located in the first housing 101, especially when the essence needs to be replenished or replaced. This design takes into account the convenience of the user and makes the maintenance process easier.

[0191] Regarding the design of the liquid storage structure, please refer to Figure 12-15 In the second embodiment, the other end of the liquid flow channel 305 is closed, and the liquid flow channel 305 is used to store the essence.

[0192] It is understandable that the difference between the second embodiment and the first embodiment is that the second embodiment does not provide a liquid storage chamber 309 specifically for storing essence, but directly stores the essence in the liquid flow channel 305 .

[0193] It should be noted that the closed end of the liquid flow channel 305 can be a design without a liquid inlet 310, which corresponds to a design without liquid replenishment, or it can be a design with a liquid inlet 310 but the liquid inlet 310 can be blocked, which corresponds to a design for liquid replenishment.

[0194] Specifically, if the design is for liquid replenishment, the liquid inlet 310 of the liquid flow channel 305 can be used as the entrance for liquid replenishment, so as to facilitate the replenishment of essence liquid into the liquid flow channel 305. After replenishment, the liquid inlet 310 of the liquid flow channel 305 can be sealed by the sealing plug 311 to ensure that no leakage occurs. Fig.14 shown.

[0195] In addition, it should be noted that the gas flow channel 304 and the liquid flow channel 305 are isolated from each other;

[0196] The liquid flow channel 305 penetrates one end of the main body 322 to form a liquid flow channel outlet;

[0197] The gas flow channel 304 penetrates through the opposite ends of the main body 322 to form a gas flow channel outlet and a gas flow channel inlet respectively;

[0198] The gas flow channel outlet and the liquid flow channel outlet are disposed at the same end of the main body 322 .

[0199] Furthermore, the liquid inlet 310 is disposed at an end of the main body 322 away from the outlet of the liquid flow channel.

[0200] Please refer again Fig.13 and Fig.15 In this embodiment, further, the liquid flow channel 305 can be arranged in a straight manner or in a circuitous manner.

[0201] Exemplarily, when the liquid flow channel 305 is arranged straight, the liquid flow channel 305 includes a liquid sub-flow channel (52);

[0202] The liquid sub-channel (52) is arranged in a straight line;

[0203] When the liquid flow channel 305 is arranged in a tortuous shape, the liquid flow channel 305 includes at least two liquid sub-flow channels (52);

[0204] A plurality of liquid sub-flow channels (52) are connected end to end in sequence to form a tortuous shape.

[0205] It should be noted that the tortuous shape means that the design of the liquid flow channel 305 is not a straight line, but has a plurality of bends, turns or curves, such as Fig.13 As shown, the essence will flow from port a at one end of a liquid flow channel 305 to port b at the other end, then from port b to port c at one end of another liquid flow channel 305, and then from port c through the liquid flow channel 305 to the other end of the liquid flow channel 305, and so on. Compared with the liquid flow channel 305 extending straight from the liquid inlet 310 of the liquid flow channel 305 to the liquid outlet 306, the tortuous design can increase the length and accommodation space of the liquid flow channel 305, which is conducive to increasing the storage capacity of the essence, thereby increasing the use time of the water light beauty head 3 and reducing the frequency of changing the beauty head or replenishing the liquid.

[0206] Please refer again Figure 6 and 9 In the present embodiment, further, the microneedle device 302, the liquid outlet 306 and the gas outlet 308 are all arranged at the end of the third shell 301 away from the first shell 101; so that the microneedle device 302 can be arranged near the position where atomization is formed on the beauty instrument (i.e., the liquid outlet 306 and the gas outlet 308). When the product is used, the skin area acted upon by the microneedle device 302 and the essence atomized particles at least partially overlaps, thereby improving the care efficiency.

[0207] It should be noted that there are two possible design methods for the relative positional relationship between the microneedle device 302 and the liquid outlet 306 and the gas outlet 308 .

[0208] In the first design method, they can be arranged in space in a side-by-side manner. This design has a simple structure and maintains a certain distance between each other to ensure the independence of their respective functions and non-interference.

[0209] In the second design, they can also be arranged in a stacked manner in space. This means that the microneedle device 302 is located in the mist outlet direction and is stacked with the liquid outlet 306 and the gas outlet 308 in the mist outlet direction. This design can make more compact use of space, reduce the overall size, and may make some internal connections and layouts more concise. This embodiment takes the second design as an example. Figure 6 and 9 shown.

[0210] Please refer again Figure 8-9In the present embodiment, further, the distance between the liquid outlet 306 and the end of the third shell 301 facing the first shell 101 is greater than the distance between the gas outlet 308 and the end of the third shell 301 facing the first shell 101, that is, the gas outlet 308 is closer to the end of the third shell 301 facing the first shell 101 than the liquid outlet 306, and the liquid outlet 306 is closer to the microneedle device 302 than the gas outlet 308.

[0211] It should be noted that, since the negative pressure zone will be formed at a certain distance from the air outlet 308, that is, the negative pressure zone will be in front of the air outlet 308, the liquid outlet 306 needs to be designed to be slightly protruding relative to the air outlet 308, so that the liquid outlet 306 can be closer to the negative pressure zone, which is more conducive to mist discharge.

[0212] Please refer again Figure 6 , 9 and 16, this embodiment is a further structural refinement of the microneedle device 302, the liquid outlet 306 and the gas outlet 308 being spatially arranged in an overlapping manner.

[0213] In this embodiment, the third housing 301 includes a first portion 3011 and a second portion 3012 connected to each other. Fig.16 As shown;

[0214] The liquid outlet 306 and the gas outlet 308 are provided in the first portion 3011;

[0215] The microneedle device 302 is mounted on the second portion 3012;

[0216] The second part 3012 covers the liquid outlet 306 and the gas outlet 308, and is provided with an atomization outlet 303 corresponding to the liquid outlet 306 or the gas outlet 308. The microneedle device 302 is provided with an avoidance hole corresponding to the position of the atomization outlet 303 for discharging the mist generated by the atomization chamber 321. At this time, the avoidance hole of the microneedle device 302 can be understood as the mist outlet 312.

[0217] It should be noted that the area where the microneedle device 302 is located needs to cover the area where the atomization outlet 303 is located, and an avoidance hole is opened at the position of the microneedle device 302 corresponding to the atomization outlet 303, so that the atomized essence can be sprayed out from the atomization outlet 303 and the avoidance hole in turn, and finally reach the skin area stimulated by the microneedle device 302, that is, the area where the microneedle device 302 and the essence spray act on the skin overlaps, so that the essence spray can form a fine skin channel on the skin through the microneedle device 302 in time to penetrate into the human skin, thereby enhancing the coordinated effect of microneedle care and atomization care, and further improving the skin care efficiency.

[0218] Optionally, the avoidance hole is opened at the center of the microneedle device 302, and the avoidance hole is coaxially arranged with the atomization outlet 303 to ensure that the mist generated by the atomization chamber 321 can be directly discharged through the avoidance hole on the microneedle device 302, thereby more effectively utilizing the fine channels formed by the microneedles on the skin, so that the essence in the mist penetrates deeper into the skin, thereby improving the beauty effect. At the same time, due to the combination of the mist outlet 312 and the microneedle device 302, the entire device is more compact and easy to operate.

[0219] Furthermore, in other embodiments, the mist outlet 312 may also be disposed close to the microneedle device 302 .

[0220] It should be noted that the mist outlet 312 is arranged near the microneedle device 302, but is not directly integrated on the microneedle device. Such a design can maintain the independence of the microneedle device 302, and is convenient for replacement or cleaning.

[0221] No matter which design is chosen, multiple factors need to be considered, such as user convenience, cleaning and maintenance of the device, and the penetration effect of the essence. In this embodiment, by cleverly designing the relationship between the microneedle device 302 and the mist outlet 312, the essence bottle can ensure the effective penetration of the essence and provide a good user experience, thus achieving a perfect combination of beauty effect and operational convenience.

[0222] In addition, since the microneedle device 302 will contact and act on the skin at a high frequency when the water light beauty head 3 is in use, in order to reduce the subjective differences in the feelings of different users about the microneedle device 302 acting on the skin, the present embodiment is designed with a buffer structure, that is, the second part 3012 is elastically connected to the first part 3011 through the spring 11, so that even if the user uses too much force or operates improperly, the microneedle device 302 can move relative to the skin after contacting the skin (at the same time, the microneedle device 302 and the second half shell 3012 move relative to the first half shell 3011 under the action of the spring 11), so that the discomfort caused by the microneedles on the microneedle device 302 irritating the skin to a large extent can be reduced, thereby improving the user experience.

[0223] Please refer again Figure 7 In this embodiment, further, the beauty instrument body 1 also includes a driving mechanism 7 arranged in the first shell 101, and the driving mechanism 7 is used to drive the water light beauty head 3 to move outward relative to the first shell 101, so that the microneedle device 302 can contact and act on the skin at a high frequency.

[0224] Since the mesotherapy head 3 needs to be in reciprocating contact with the skin to better promote the absorption of the essence, in this embodiment, the driving mechanism 7 may include a driving device 701, and the driving device 701 alone can provide a reciprocating driving force to the mesotherapy head 3. In this case, the driving device 701 is a reciprocating driving device. Alternatively, the driving mechanism 7 may include a driving device 701 and an elastic reset member, and the two cooperate with each other to realize the reciprocating drive of the mesotherapy head 3, that is, the mesotherapy head 3 moves outward for a certain stroke under the drive of the driving device 701. After the driving force of the driving device 701 is withdrawn, the mesotherapy head 3 will return under the action of the elastic reset member, thereby realizing reciprocation. In this case, the reciprocating driving device includes the driving device 701 and the elastic reset member.

[0225] Exemplarily, the elastic return member may be a spring.

[0226] It can be understood that no matter which of the above reciprocating drive settings is used, compared with the user manually operating the beauty instrument to make the water light beauty head 3 reciprocate on the human facial skin, the automated method can provide a more uniform and stable reciprocating drive, while eliminating the manual reciprocating movement operation, thereby improving the user experience.

[0227] In addition, similarly, when setting the driving mechanism 7, it is considered that if the driving mechanism 7 is set in the hyaluronic acid beauty head 3, the structure of the hyaluronic acid beauty head 3 will be very complicated and the volume will be large, the design difficulty will increase, and the reliability will be reduced. At the same time, when the hyaluronic acid beauty head 3 is damaged after long-term use and needs to be replaced, or when the hyaluronic acid beauty head 3 needs to be designed as a disposable product, the disposal cost of the hyaluronic acid beauty head 3 composed of too many parts will be very high. Therefore, this embodiment chooses to set the driving mechanism 7 in the beauty instrument body 1 to reduce the structural complexity of the hyaluronic acid beauty head 3 and reduce the disposal cost.

[0228] Please refer again Figure 7-8 , and combined with reference Fig.16 In this embodiment, further, the air inlet 307 is connected to the air supply mechanism 8 through the air delivery hose 9.

[0229] It should be noted that, when in use, the water light beauty head 3 is driven by the driving mechanism 7 as a whole to move outward, but at the same time the water light beauty head 3 needs to be supplied with gas by the gas supply mechanism 8 to atomize the essence. Therefore, in order to adapt to the outward movement, the air inlet 307 of the gas flow channel 304 is connected to the gas supply mechanism 8 through a gas supply hose 9 with good flexibility to improve the structural reliability and durability, thereby ensuring a stable gas supply.

[0230] Please refer again Fig.16 , and combined with reference Figure 20-21 In this embodiment, further, it also includes a connecting component 702 disposed in the first housing 101;

[0231] The driving mechanism 7 comprises a driving device 701;

[0232] One end of the connecting component 702 is connected to the third housing 301, and the other end of the connecting component 702 is connected to the driving device 701;

[0233] It should be noted that the driving device 701 is a core power source, which is electrically connected to the circuit board 102 to provide stable and continuous power output. It can be precisely controlled according to the needs of the user or the preset program to ensure that the water light beauty head 3 moves at a suitable speed and strength.

[0234] The connection component 702 is responsible for connecting the driving device 701 and the water light beauty head 3. One end of the connection component 702 is connected to the third shell 301 to ensure that the power can be accurately transmitted to the water light beauty head 3; the other end is connected to the driving device 701 to ensure a stable connection between the power source and the moving parts. This connection method not only ensures the efficiency of power transmission, but also makes the replacement and maintenance of the water light beauty head 3 more convenient and quick.

[0235] In this embodiment, further, the driving device 701 includes an output shaft 703, the driving device 701 is arranged transversely in the first direction, the output shaft 703 is parallel to the first direction, and the movement direction of the connecting component 702 is parallel to the second direction;

[0236] The connecting assembly 702 is eccentrically connected to the output shaft 703 of the driving device 701;

[0237] Wherein, the first direction is a direction perpendicular to the reciprocating motion direction of the microneedle device 302;

[0238] The second direction is the reciprocating direction of the microneedle device 302 .

[0239] Exemplarily, the driving device 701 may include a motor, and the motor and the connecting assembly 702 may be combined to form a reciprocating driving device.

[0240] It should be noted that the horizontal arrangement of the driving device 701 in a direction perpendicular to the reciprocating motion direction of the microneedle device 302 reduces the space utilization of the driving mechanism 7 in the motion direction of the microneedle device 302, and is also beneficial to the arrangement of other components in the first shell 101 in a direction perpendicular to the linear reciprocating motion direction of the microneedle device 302, thereby helping to reduce the overall volume of the beauty instrument, realize a miniaturized design, and facilitate holding, storage and carrying.

[0241] It is understandable that if the water light beauty head 3 is designed to be detachable, the third shell 301 and the connecting component 702 need to be connected in a detachable manner, such as a snap connection, a magnetic connection, etc.

[0242] Please refer again Fig.16 , 20 -21, in this embodiment, further, the connecting assembly 702 includes a connecting piece 7022, and the gas supply mechanism 8 is connected to the mist outlet device through the connecting piece 7022, and is used to transport gas into the mist outlet device through the connecting piece 7022;

[0243] The driving mechanism 7 is connected to the connecting member 7022 and is used to drive the connecting member 7022 to move, so as to drive the third housing 301 to move;

[0244] The air delivery hose 9 passes through the middle portion 1012 and is connected between the air supply mechanism 8 and the connector 7022 , thereby connecting the air supply mechanism 8 and the mist outlet device.

[0245] The connecting member 7022 includes a first sleeve portion 70221 and a connecting portion 70222 connected to each other;

[0246] The third housing 301 is inserted into the first sleeve portion 70221;

[0247] The output shaft 703 is connected to the connecting portion 70222;

[0248] Specifically, the first sleeve portion 70221 is used to conveniently connect with the third housing 301 by plugging. This plug-in connection method not only ensures the stability of the connection, but also makes the replacement and maintenance of the third housing 301 (i.e., the water light beauty head 3) simpler and more convenient.

[0249] The connecting portion 70222 is responsible for connecting with the output shaft 703. The output shaft 703, as the power output end of the driving device 701, is tightly connected with the connecting member 7022 through the connecting portion 70222, thereby ensuring the stable transmission of the driving force. This connection method ensures the efficient transmission of the driving force, and also makes the movement of the entire driving mechanism 7 more stable and controllable.

[0250] Please refer again Fig.16 , 20 -21, in this embodiment, further, the connecting assembly 702 further includes an eccentric wheel 7021;

[0251] The connecting member 7022 further includes a second sleeve connecting portion 70223, and the first sleeve connecting portion 70221, the connecting portion 70222 and the second sleeve connecting portion 70223 are connected in sequence;

[0252] The eccentric wheel 7021 is located in the second sleeve portion 70223 , and the eccentric wheel 7021 is connected to the output shaft 703 of the driving device 701 .

[0253] It should be noted that, due to the presence of the eccentric wheel 7021, when the driving device 701 drives the eccentric wheel 7021 to rotate through the output shaft 703, the eccentric wheel 7021 will drive the connecting member 7022 to reciprocate along a straight line, so that the water light beauty head 3 is driven by the connecting member 7022 to repeatedly contact and leave the user's face to achieve a beauty action. In addition, the third housing 301, the eccentric wheel and the connecting member 7022 are all sleeved, which can increase the mutual contact area, thereby improving the connection stability, and further ensuring the stability of the driving movement.

[0254] It is understandable that in order to reduce vibration, a shock-absorbing sleeve can be installed on the outside of the driving device 701 to reduce the impact of vibration generated when the driving device 701 rotates on the beauty instrument and user experience, while also improving structural reliability and durability.

[0255] In this embodiment, further, the gas delivery hose 9 crosses the second sleeve connection portion 70223 and is connected to the connecting piece 7022 , and the gas delivery hose 9 is connected to the mist outlet device through the connecting piece 7022 .

[0256] Specifically, the gas hose 9 is designed to cross the second sleeve portion 70223 and connect to the connector 7022. Such a layout reasonably utilizes the space above the second sleeve portion 70223, and at the same time enables the gas hose 9 to fit on the connector 7022, reducing the possibility of gas leakage caused by looseness or displacement of the hose. In addition, the design of crossing the second sleeve portion 70223 also enables the gas hose 9 to better withstand the pulling force during movement, thereby improving its durability and stability.

[0257] In this embodiment, further, the height of the driving mechanism 7 in the axial direction is not greater than the maximum width of the first sleeve portion 70221 in the direction parallel to the axial direction of the driving mechanism 7; and / or,

[0258] The maximum width of the driving mechanism 7 in a direction perpendicular to the axial direction thereof is not greater than the maximum width of the first sleeve portion 70221 in a direction perpendicular to the axial direction of the driving mechanism 7 .

[0259] It should be noted that the driving device 701 is connected to the second sleeve portion 70223 through the eccentric wheel 7021, so that the axial dimensions of the driving device 701, the eccentric wheel 7021 and the second sleeve portion 70223 in the driving mechanism 7 (specifically the driving device 701) (i.e., the height of the driving mechanism 7) can be designed to be smaller than the axial dimension of the first sleeve portion 70221 in the driving mechanism 7 (i.e., the width of the first sleeve portion 70221). In this way, the structure of the internal components of the beauty instrument can be made more compact, and other components in the beauty instrument except the driving mechanism 7 can be prevented from occupying too much space in the axial direction of the driving mechanism 7, thereby reducing the overall volume of the beauty instrument and being more conducive to the miniaturized design of the product.

[0260] Similarly, the maximum width of the driving mechanism 7 in a direction perpendicular to its axial direction is designed to be no greater than the maximum width of the first sleeve portion 70221 in a direction perpendicular to the axial direction of the driving mechanism 7, which is also in line with the trend of product miniaturization.

[0261] In this embodiment, further, the first sleeve portion 70221, the connecting portion 70222 and the second sleeve portion 70223 are connected to form an L shape and form an escape space, and the driving device 701 is located in the escape space.

[0262] It should be noted that, specifically, the L-shaped structure optimizes the spatial layout, so that the connector 7022 occupies a relatively small volume in the three-dimensional space, and the setting of the avoidance space fully considers the size and installation requirements of the drive device 701. By placing the drive device 701 in the avoidance space, it is avoided that the drive device 701 needs to occupy more space, and it also avoids spatial conflicts with other components, thereby ensuring that it can work stably and reliably.

[0263] In addition, this design also helps to reduce the size and weight of the entire beauty instrument, making it easier to carry and use, meeting the needs of miniaturization and portability. At the same time, due to the compact structure, the connection between the components is more stable, improving the stability and durability of the entire device.

[0264] Please refer again Figure 7-8 , 16 and 20, in this embodiment, further, the gas inlet 307 of the gas flow channel 304, the first sleeve portion 70221 and the gas supply mechanism 8 are connected in sequence.

[0265] It should be noted that the third shell 301 is detachably fixed in the first sleeve portion 70221, that is, there is a first sleeve portion 70221 between the air inlet 307 of the gas channel 304 and the gas supply mechanism 8. In this way, it can be understood that the first sleeve portion 70221 is provided with a conducting hole, through which the air inlet 307 of the gas channel 304 and the gas supply mechanism 8 are connected, so that the gas supply mechanism 8 can smoothly transport the gas to the air inlet 307 of the gas channel 304.

[0266] Of course, the air inlet 307 and the air supply mechanism 8 can also be directly connected without passing through the first sleeve portion 70221. For example, the first sleeve portion 70221 has a hollow design, and the air inlet 307 and the air supply mechanism 8 are directly connected through the hollow design of the first sleeve portion 70221.

[0267] Please refer again Fig.16 In this embodiment, a first sealing member is provided at the position where the pneumatic atomizing device is connected to the air supply mechanism 8. Fig.16 The sealing ring 10;

[0268] Specifically, a sealing ring 10 is provided between the third housing 301 and the first sleeve connection portion 70221;

[0269] Alternatively, a sealing ring 10 is provided between the third shell 301 and the air supply mechanism 8 .

[0270] It should be noted that in order to ensure that the gas coming out of the gas supply mechanism 8 does not leak from the junction of the third shell 301 and the first sleeve part 70221 at the air inlet 307 of the gas flow channel 304 after passing through the first sleeve part 70221, thereby affecting the atomization effect of the gas path, this embodiment is designed to provide a sealing ring 10 at the junction of the third shell 301 and the first sleeve part 70221, and the sealing ring 10 realizes the sealing of the junction to prevent gas leakage.

[0271] It is understandable that the sealing ring 10 is provided between the third shell 301 and the air supply mechanism 8 in the same manner.

[0272] Furthermore, the sealing ring 10 is sleeved on the outer circumference of the portion of the third housing 301 located inside the first sleeve portion 70221;

[0273] Alternatively, the sealing ring 10 is sleeved on the outer circumference of the portion of the third shell 301 connected to the air supply mechanism 8 .

[0274] It should be noted that, considering that if the sealing ring 10 is set in the first sleeve part 70221, the sealing ring 10 is prone to be damaged during use after the third shell 301 is plugged and unplugged many times, thereby reducing its sealing reliability, the present embodiment chooses to sleeve the sealing ring 10 on the outer periphery of the part of the third shell 301 located in the first sleeve part 70221. In this way, if the hyaluronic acid beauty head 3 is a disposable design, the sealing ring 10 will be replaced together with the hyaluronic acid beauty head 3. If the hyaluronic acid beauty head 3 is not a disposable design, it is also convenient to replace the sealing ring 10 when the sealing ring 10 is damaged during use to meet usage requirements.

[0275] It can be understood that the sealing ring 10 is sleeved on the outer circumference of the portion of the third shell 301 connected to the air supply mechanism 8 in the same manner.

[0276] Please refer again Fig. 9 In this embodiment, further, the liquid storage chamber 309 is arranged around the atomization bin 321, and two second sealing members 18 are arranged at intervals between the outer wall of the atomization bin 321 and the outer wall of the liquid storage bin, and the liquid inlet 310 is located between the two second sealing members 18;

[0277] Alternatively, a second sealing member 18 is sleeved on the outer circumference of the liquid inlet 310 .

[0278] It should be noted that the liquid inlet 310 is provided in the atomization bin 321 and communicates with the liquid storage chamber 309, so that the liquid in the liquid storage chamber 309 flows into the atomization bin 321 for atomization. The position and size design of the liquid inlet 310 are very critical, which directly affects the flow speed of the liquid and the atomization effect.

[0279] The second sealing member 18 is provided to ensure the sealing between the atomizing chamber 321 and the liquid storage chamber 309, and to prevent the liquid from leaking when it flows from the liquid storage chamber 309 into the atomizing chamber 321. According to the description of this embodiment, there are at least two possible configuration modes:

[0280] In a first possible arrangement, the liquid storage chamber 309 is arranged around the atomization chamber 321, such as Fig. 9 As shown:

[0281] In this case, there are two second seals 18 spaced apart between the outer wall of the atomizing bin 321 and the outer wall of the liquid storage chamber 309, and the liquid inlet 310 is located between the two seals. This design prevents the liquid from leaking outwards when it flows from the liquid storage chamber 309 to the atomizing bin 321 due to the obstruction of the two seals.

[0282] In a second possible arrangement, the liquid storage chamber 309 is arranged around the atomization chamber 321, or the liquid storage chamber 309 and the atomization chamber 321 are arranged side by side:

[0283] In this case, the second sealing member 18 is sleeved on the outer peripheral side of the liquid inlet 310. Although this design only provides one sealing point, since the liquid inlet is a key position, this arrangement can still effectively prevent liquid leakage.

[0284] Please refer again Fig. 9 In this embodiment, further, the liquid inlet 310 is opened at a position corresponding to the bottom position of the liquid storage chamber 309.

[0285] It should be noted that, as mentioned above, the structural design of the first shell 101 is ergonomic, that is, when the user is using the hyaluronic acid beauty instrument, the hyaluronic acid beauty head 3 is tilted, and the lowest liquid level of the essence in the liquid storage chamber 309 will be located at the bottom of the liquid storage chamber 309. At this time, the liquid inlet 310 opened at the bottom position of the corresponding liquid storage chamber 309 can more easily guide the essence concentrated at the bottom position of the liquid storage chamber 309, reduce the residual essence in the liquid storage chamber 309, improve the utilization rate of the essence, and thus reduce waste.

[0286] In addition, there is an anti-fool-proof installation design between the third shell 301 and the first shell 101. Through the anti-fool-proof design, the correct installation of the water light beauty head 3 and the beauty instrument body 1 can be guaranteed, so that the liquid inlet 310 is set toward the lowest liquid level of the essence.

[0287] Specifically, the third housing 301 is provided with a foolproof structure;

[0288] An accommodation space is provided on the first shell 101 at a position corresponding to the fool-proof structure, and the fool-proof structure is located in the accommodation space.

[0289] Please refer to Figure 17-19 In this embodiment, further, the water light beauty head 3 also includes a protective cover 313;

[0290] The protection cover 313 is disposed on a position of the third housing 301 corresponding to the microneedle device 302 .

[0291] It should be noted that, by providing the protective cover 313, when the water light beauty head 3 is idle, especially when the water light beauty head 3 is removed from the beauty instrument body 1 and placed, the microneedle device 302 can be protected from being contacted by external objects to prevent it from being damaged. At the same time, it also reduces external pollution and improves hygiene and safety, and reduces the possibility that the beauty effect is adversely affected by the outside world.

[0292] Exemplarily, the protective cover 313 is generally a buckle cover in a cylindrical shape, which is adapted to the shape of the third shell 301 .

[0293] In one embodiment, a silicone pad 314 may be disposed inside the protective cover 313 .

[0294] It should be noted that the silicone pad 314 has good shockproof performance, which can effectively reduce the vibration when the water light beauty head 3 falls or receives an impact, thereby reducing the possibility of damage to the microneedle device 302 due to strong vibration.

[0295] It is understandable that in order to better protect the microneedle device 302, the silicone pad 314 has a hollow position design, which corresponds to the microneedle device 302, so as to protect the microneedle device 302 from being affected by strong vibrations while the silicone pad 314 itself will not exert pressure on the microneedle device 302 due to contact with the microneedle device 302.

[0296] Please refer again Figure 18-19 In this embodiment, further, an anti-blocking member 315 is provided inside the protective cover 313;

[0297] The anti-blocking member 315 passes through the atomizing outlet 303 and is inserted into the liquid outlet 306 .

[0298] It should be noted that the diameter of the liquid outlet 306 is very small. After use, since there is a certain amount of essence liquid remaining in the liquid outlet 306, the essence liquid remaining in the liquid outlet 306 is easy to cause the liquid outlet 306 to be blocked after drying. Once blocked, it not only affects the use but also is inconvenient to clean. For this reason, this embodiment provides an anti-blocking member 315 in the protective cover 313. When the beauty instrument is idle, the protective cover 313 is covered on the third shell 301, and the anti-blocking member 315 passes through the atomization outlet 303 and is inserted into the liquid outlet 306, thereby reducing the essence liquid remaining in the liquid outlet 306; when it is used again, the protective cover 313 is opened, and the anti-blocking member 315 is pulled out of the liquid outlet 306, and a small amount of essence liquid solidified material remaining in the liquid outlet 306 can also be taken out, thereby reducing the accumulation of solidified material of the essence liquid and reducing the possibility of the liquid outlet 306 being blocked.

[0299] Please refer again Figure 18-19 , and combined with reference Fig.25 In this embodiment, further, a first limiting structure 15 is provided on the inner side of the protective cover 313 , and after the first limiting structure 15 contacts the mist outlet device in the third shell 301 , it can limit the depth of the anti-blocking member 315 inserted into the liquid outlet 306 .

[0300] It should be noted that it is not sufficient to simply insert and remove the anti-blocking member 315 for adjustment. Without an effective limit mechanism, the anti-blocking member 315 may be inserted too deeply into the liquid outlet 306, which may lead to some adverse consequences, such as damaging the structure of the liquid outlet or making it difficult to remove the anti-blocking member 315.

[0301] In order to solve this problem, the present embodiment introduces a first limiting structure 15. The function of this structure is that when the anti-blocking member 315 is inserted into the liquid outlet 306, once the first limiting structure 15 comes into contact with the housing 1, it will act as a block or stopper to limit the anti-blocking member 315 from further entering the liquid outlet 306.

[0302] In this way, the first limiting structure 15 ensures that the anti-blocking member 315 has a suitable depth when inserted into the liquid outlet 306, so that it can play its anti-blocking function without being inserted too deeply to cause other problems. This increases the reliability and safety of the device and also makes the operation easier and more accurate.

[0303] Please refer again Figure 18-19 ,as well as Fig.25 In the present embodiment, further, the first limiting structure 15 is arranged on the peripheral side of the anti-blocking member 315 away from one end of the protective cover 313 , and an escape space is formed between the first limiting structure 15 and the anti-blocking member 315 .

[0304] It should be noted that when the anti-blocking member 315 is inserted into the liquid outlet 306, the first limiting structure 15 abuts against the peripheral side of the gas outlet 308 and the liquid outlet 306, and the gas outlet 308 and the liquid outlet 306 are directly opposite to the avoidance space, so as to avoid the gas outlet 308 and the liquid outlet 306 from being damaged by the interference of the first limiting structure 15, thereby affecting the mist discharge function. Such a design not only ensures the functionality of the first limiting structure 15, but also avoids interference with the liquid outlet 306 and the gas outlet 308 due to the avoidance space, provides sufficient space for the liquid outlet 306 and the gas outlet 308, and ensures the stability and reliability of the entire structure.

[0305] Please refer again Figure 18-19 In this embodiment, further, a second limiting structure 16 is provided inside the protective cover 313, and a third limiting structure 17 cooperating with the second limiting structure is provided on the third housing 301;

[0306] When the protective cover 313 is covered on the third housing 301 , the second limiting structure 16 contacts the third limiting structure 17 to limit the relative position of the protective cover 313 and the third housing 301 .

[0307] It should be noted that the second limiting structure 16 and the third limiting structure 17 not only play the role of limiting the covering of the protective cover 313 and the third shell 301, but also play the role of limiting the anti-blocking component 315 from being inserted too deeply into the liquid outlet 306. The first limiting structure 15 is the first level of limiting protection, and the second limiting structure 16 and the third limiting structure 17 are the second level of limiting protection.

[0308] Please refer again Figure 6 , 9 and 18. In this embodiment, further, the microneedle device 302 is disposed between the protective cover 313 and the liquid outlet 306. The water light beauty head 3 is provided with an atomization outlet 303, and the atomization outlet 303 is connected to the liquid outlet 306;

[0309] The microneedle device 302 is provided with a mist outlet 312 at a position corresponding to the atomization outlet 303 , and the anti-blocking member 315 is inserted into the liquid outlet 306 through the mist outlet 312 .

[0310] It should be noted that in order to allow more atomized essence to be sprayed onto the skin where the microneedle device 302 acts, further promote the absorption of the atomized essence, and improve the skin care effect, the area where the microneedle device 302 is located needs to cover the area where the atomization outlet 303 is located, and the microneedle device 302 is designed to have a mist outlet 312 at the position corresponding to the atomization outlet 303, so that the atomized essence can be sprayed from the atomization outlet 303 and the mist outlet 312 in turn, and finally reach the skin stimulated by the microneedle device 302.

[0311] Optionally, the mist outlet 312 is opened at the center of the microneedle device 302, and the mist outlet 312 is coaxially arranged with the atomization outlet 303 to ensure that the skin area stimulated once by the microneedle device 302 can evenly absorb the atomized essence.

[0312] Please refer again Fig. 9 In this embodiment, further, if a liquid storage chamber 309 is designed, the liquid storage chamber 309 is provided with an air pressure regulating hole 316 , and the air pressure regulating hole 316 is provided with an air-permeable liquid-blocking member 317 .

[0313] If the liquid storage chamber 309 is not designed, the liquid flow channel 305 is provided with an air pressure regulating hole 316 , and the air pressure regulating hole 316 is provided with an air-permeable and liquid-blocking member 317 .

[0314] It should be noted that, first of all, the purpose of providing the air pressure regulating hole 316 is to regulate the internal air pressure, whether in the liquid storage chamber 309 or the liquid flow channel 305. During the operation of the beauty instrument, the air pressure in the liquid storage chamber 309 or the liquid flow channel 305 will decrease due to the consumption of the essence, thereby affecting the supply of the essence. In order to maintain the stability of the air pressure, there needs to be a way to balance the air pressure difference between the inside and the outside, and the air pressure regulating hole 316 plays such a role.

[0315] Specifically, the air pressure regulating hole 316 can be set at a place far away from the lowest liquid level of the essence. In addition, the air-permeable liquid-blocking member 317 set in the air pressure regulating hole 316 allows air to pass through while preventing the leakage of the essence. Specifically, the air-permeable liquid-blocking member 317 can be a material with air permeability but not liquid permeability, such as some special porous materials or films. In this way, at the air pressure regulating hole 316, air can flow freely, thereby balancing the air pressure inside and outside the liquid storage cavity 309 or the liquid flow channel 305; and the essence is blocked due to the presence of the air-permeable liquid-blocking member 317 and will not leak out of the air pressure regulating hole 316.

[0316] The design of the air pressure regulating hole 316 and the air-permeable liquid-blocking member 317 achieves the purpose of stabilizing the air pressure in the liquid storage chamber 309 or the liquid flow channel 305, while also preventing accidental leakage of the essence. This not only enhances the stability and safety of the beauty instrument, but also provides users with a more comfortable and secure skin care experience.
