[0186] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions 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, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, it is known to those of ordinary skill in the art 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.

[0187] In the description of this application, it should be understood that, unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by those skilled in the art to which this application belongs. In addition, any terminology used is only for the purpose of describing specific embodiments and is not intended to limit this application.

[0188] In addition, numerous specific details are provided in the detailed description below to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0189] The technical solution of the present application will be further explained below with reference to the accompanying drawings and through specific implementation methods.

[0190] In view of the aforementioned shortcomings of the related art, the applicant, drawing upon years of extensive practical experience and expertise in the design and manufacture of such products, combined with the application of academic knowledge, has actively engaged in research and innovation, hoping to develop a technology that can address these shortcomings and make beauty devices more practical. Through continuous research and design, and through repeated trial production and refinement, the present invention has been finally created, which possesses truly practical value.

[0191] Referring to Figures 1-8 , an embodiment of the present application provides a multifunctional beauty instrument, characterized by comprising a beauty instrument body 1 (as shown in Figure 3 ) and two different types of beauty heads, the two different types of beauty heads being an ion beauty head 2 with a microcurrent beauty function (as shown in Figures 4-5 ) and a water light beauty head 3 with a hydrating and penetration-promoting beauty function (as shown in Figure 6 );

[0192] 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 , which is electrically connected to the circuit board 102 .

[0193] The ion beauty head 2 and the water light beauty head 3 are 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 , as shown in FIG24 ;

[0194] The ion beauty head 2 includes a second conductive portion 202 . When the ion beauty head 2 is mounted 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 .

[0195] It is understood that when the ion beauty head 2 shown in Figures 4 and 5 is installed on the beauty device body 1 shown in Figure 3, the resulting beauty device is an ion introduction and export beauty device, as shown in Figure 1. When the water light beauty head 3 shown in Figure 6 is installed on the beauty device body 1 shown in Figure 3, the resulting beauty device is a water light beauty device, which can also be called a water light device, as shown in Figure 2.

[0196] 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 usage costs, facilitate storage management and carrying, and enhance user experience, this embodiment improves the beauty instrument from the original non-detachable structural design to a detachable structural 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 to 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.

[0197] Since the ion beauty head 2 in this embodiment utilizes microcurrent, it requires a power source. This power source is typically located within the first housing 101, where ample space is available. Therefore, an electrical connection is required between the ion beauty head 2 and the power source located within the first housing 101. The combination of the second conductive portion and the circuit board 102 creates a pathway for electrical connection between the ion beauty head 2 and the power source located within the first housing 101. When the ion beauty head 2 is mounted on the outside of the first housing 101 or the water-light beauty head 3, the second conductive portion 202 conducts electricity to the circuit board 102, allowing the power source to supply electrical energy to the ion beauty head 2. It is understood that the power source may not be located directly within the first housing 101. Instead, the ion beauty head 2 may be electrically connected to an external power source via the circuit board 102 within the first housing 101, with the external power source providing power to the ion beauty head 2.

[0198] 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. This can reduce the volume of the product, making the entire beauty instrument compact and lightweight, 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. This can improve the integrity of the beauty instrument, making the entire beauty instrument more coordinated and unified in appearance and use, and more convenient to carry and store.

[0199] In the second configuration, the water light beauty head 3 can be detachably mounted on the first housing 101, or it can 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. 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 portion 202 of the ion beauty head 2 is 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.

[0200] It is understood that circuit board 102 can be a full board or a smaller board, depending on the design and functional requirements of the beauty device. A full board may contain more circuit components and a more complex circuit design, while a smaller board may be more concise and focused on a specific function. Whether full board or smaller board, they both play a vital role in ensuring the stable operation and functional performance of the beauty device.

[0201] Optionally, a sensor for sensing the human body may be provided on the ion beauty head 2. When the ion beauty head 2 comes into contact with human skin, the sensor senses the human body, and the circuit board 102 controls the power supply to supply power to the ion beauty head 2, thereby preventing the ion beauty head 2 from doing ineffective work. That is, when the user forgets to turn off or accidentally turns on the beauty instrument, the ion beauty head 2 still outputs microcurrent, thereby saving energy consumption and improving the intelligence of the beauty instrument.

[0202] The sensor may be, but is not limited to, an infrared sensor, a temperature sensor, or a distance sensor. The sensor detects the human skin or the distance between the product and the human body. If the human skin 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. If the human skin 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.

[0203] 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 the various functions of the beauty instrument body 1. In view of the fact that these structural designs have been implemented in many related technologies and are not the focus of the design of this solution, they will not be elaborated in depth here.

[0204] Please refer to Figures 4-5 again. In this embodiment, the ion beauty head 2 further includes a second shell 201. The second shell 201 is installed outside the first shell 101 or the water light beauty head 3. The second conductive part 202 is provided in the second shell 201.

[0205] Please refer to FIG7 again. In the first embodiment, the first conductive portion 103 may be a conductive member provided on the surface of the first housing 101.

[0206] Please refer to FIG8 again. 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.

[0207] It should be noted that, regardless of the first or second embodiment, the design purpose is to achieve electrical conduction between the first shell 101 and 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.

[0208] It should be noted that, during use, the first conductive portion 103 and the second conductive portion 202 form a closed circuit through the human body. Depending on the user's selection of the ion beauty mode, the beauty device can either introduce beauty ingredients or remove skin impurities, thereby improving skin condition. In this way, a single ion beauty head can meet two different beauty needs, improving product convenience and enhancing the user experience. It is understood that the ion beauty head can be configured to have only a single introduction or export function. In this case, it is only necessary to set the first conductive portion 103 and the second conductive portion 202 to a single polarity.

[0209] The principle of iontophoresis is as follows: when iontophoresis mode is activated, the second conductive portion 202 of the ion beauty head 2 serves as the positive electrode, and the first conductive portion 103 of the beauty device body 1 serves as the negative electrode. When the user grips the beauty device body 1 and contacts the first conductive portion 103, and the second conductive portion 202 contacts the skin, a current loop is formed between the body, the first conductive portion 103, the circuit board 102, and the second conductive portion 202. A microcurrent flows from the circuit board 102, travels to the second conductive portion 202, passes through the body, and returns to the circuit board 102 from the first conductive portion 103. Under the influence of the electric field, the positively charged active ingredients in the nutrient essence applied to the skin are repelled by the second conductive portion 202 of the same polarity, moving toward the skin and penetrating deep into the skin, thereby promoting absorption of the nutrient essence and achieving a beautifying and nourishing effect.

[0210] The principle of ion extraction (similar to ion introduction): When ion extraction mode is activated, the first conductive portion 103 of the beauty device body 1 serves as the positive electrode, and the second conductive portion 202 serves as the negative electrode. When the user grips the beauty device body 1 and touches the first conductive portion 103, and the second conductive portion 202 contacts the skin, a current loop is formed between the body, the first conductive portion 103, the circuit board 102, and the second conductive portion 202. A microcurrent flows from the circuit board 102, is transmitted to the first conductive portion 103, passes through the body, and then returns to the circuit board 102 through the second conductive portion 202. Under the influence of the electric field, dirt carrying negative ions in the human skin is repelled by the skin of the same polarity and discharged, achieving a cleansing effect.

[0211] It's important to note that, in practical applications, the selection and use of conductive parts or conductive materials must take into account factors such as safety, conductivity, and durability to ensure the stability and safety of the beauty device. Furthermore, the design of the conductive parts or conductive materials must be coordinated with the overall design and functional requirements of the beauty device to achieve the best user experience and results.

[0212] In this embodiment, the specific forms of the first conductive portion 103 and the second conductive portion 202 are further refined.

[0213] On the one hand, the first conductive part 103 can be in the form of a conductive electrode sheet, that is, the conductive member provided on the surface of the first shell 101 is a conductive electrode sheet, and the second conductive part 202 can also be in the form of a conductive electrode sheet;

[0214] It should be noted that the conductive electrode sheet generally has high electrical conductivity and stability, and can ensure stable and reliable current transmission between the beauty instrument body 1 and the ion beauty head 2.

[0215] 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, while the second conductive part 202 is still in the form of a conductive electrode sheet.

[0216] It should be noted that the conductive film, such as a hydroplated film, has good conductivity and flexibility and can cover the entire surface or a portion of the first housing 101, thereby increasing the conductive area and conductive performance of the beauty device. The second conductive portion 202 is in the form of a conductive electrode sheet, which ensures a stable connection with the first conductive portion 103.

[0217] It's important to note that the choice of conductive film and conductive electrode sheet should be determined based on the specific application scenario and requirements. Conductive film may be more suitable for applications requiring large-area or flexible conductivity, while conductive electrode sheets may be more suitable for applications requiring high conductivity and stability. Furthermore, the specific shape, size, and layout of the conductive film and conductive electrode sheets should be designed and optimized based on the overall design and functional requirements of the beauty device.

[0218] In this embodiment, the first housing 101 further includes a contact terminal 6 electrically connected to the circuit board 102, as shown in FIG3 . The ion beauty head 2 further includes a connection terminal 5 electrically connected to the second conductive portion 202. As shown in FIG5 , the second conductive portion 202 is electrically connected to the circuit board 102 via the connection terminal 5 and the contact terminal 6.

[0219] 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 through the connection terminal 5 and the contact terminal 6.

[0220] It should be noted that since the ion beauty head 2 is detachably connected to the first housing 101 or the outer side of the water light beauty head 3, in order to ensure that the second conductive portion 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.

[0221] In this embodiment, the structure of the first housing 101 has been further redesigned to accommodate the detachable mounting of the ion beauty head 2 and the water-light beauty head 3. Specifically, the first housing 101 includes a dedicated mounting position 4, as shown in Figure 3. This mounting position 4 allows for the detachable mounting of the ion beauty head 2 and the water-light beauty head 3. This design not only enhances the modularity of the beauty device, allowing users to flexibly replace the beauty heads according to their needs, but also ensures stable installation and ease of use.

[0222] This design allows users to easily swap between the ion beauty head 2 and the water light beauty head 3 according to their skincare needs, achieving different skincare effects. Furthermore, the standardized design of the mounting position 4 makes the beauty head replacement process simple and quick, eliminating the need for complex operations, further enhancing the user experience.

[0223] In this embodiment, the design of the mounting position 4 has been further refined. Specifically, a mounting groove 12 is provided on the mounting position 4, as shown in Figure 3. This groove 12 is designed to ensure that the ion beauty head 2 and the water light beauty head 3 can be smoothly installed and tightly integrated with the mounting position 4. The shape of the groove 12 matches the shapes of the ion beauty head 2 and the water light beauty head 3, thus ensuring stable and precise installation.

[0224] Another design solution is also considered, whereby mounting grooves 12 are respectively provided on the ion beauty head 2 and the water light beauty head 3, and the mounting position 4 is designed to match the shape of these mounting grooves 12. In this design solution, 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.

[0225] Both designs effectively enhance the modularity and ease of use of the beauty device. Users can select the appropriate beauty head according to their needs and conveniently install it on the device. Furthermore, the matching shape of the mounting slot 12 and the beauty head makes installation easier and faster, enhancing the user experience.

[0226] It is understood that in addition to the aforementioned snap-on connection, there are a variety of other options for connecting the ion beauty head 2 and the water light beauty head 3 to the first housing 101. Threaded and magnetic connections are both common and practical connection methods. It is also understood that both connection methods can be used simultaneously, for example, by combining a snap-on connection with a magnetic connection to further ensure the connection reliability between the beauty head and the first housing 101.

[0227] For a threaded connection, the bottom or side of the ion beauty head 2 and the water light beauty head 3 can be designed with threads (e.g., external threads), while the mounting position 4 on the first housing 101 is also designed with corresponding threads (e.g., internal threads). By rotating the ion beauty head 2 or the water light beauty head 3, they can be tightly connected to the first housing 101. This connection method is highly stable and durable, ensuring that it is not likely to loosen or fall off during use.

[0228] For a magnetic connection, magnets can be embedded in the bottoms of the ion beauty head 2 and the water light beauty head 3, while the mounting area 4 of the first housing 101 is provided with or made of magnetic material. When the ion beauty head 2 or the water light beauty head 3 is brought close to the mounting area 4, they automatically attach due to magnetic attraction, achieving a quick and secure connection. This connection method is easy to use and provides a good user experience, making it particularly suitable for users who value speed and convenience.

[0229] In this embodiment, to ensure a secure connection between the ion beauty head 2 and the first housing 101 and to ensure accurate and reliable circuit connection, the mounting position 4 further includes a first engaging surface 13 for contact with the ion beauty head 2. As shown in FIG3 , this first engaging surface 13 tightly mates with the ion beauty head 2 during installation, ensuring stable installation and reliable contact. Furthermore, the contact terminals 6 are cleverly designed on the first engaging surface 13 so that when the ion beauty head 2 is properly installed, the internal connecting terminals 5 can directly contact the contact terminals 6, achieving circuit connection.

[0230] Correspondingly, the ion beauty head 2 also has a second bonding surface 14 that contacts the first bonding surface 13, as shown in Figure 5. This second bonding surface 14 matches the first bonding surface 13 in shape and size, ensuring a tight fit between them. The connection terminal 5 is located on the second bonding surface 14. When the ion beauty head 2 is installed in the mounting position 4, the connection terminal 5 can precisely mate with the contact terminal 6, enabling electrical signal transmission.

[0231] In addition, the surface where the ion beauty head 2 connects 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 seamlessly integrated, which is more beautiful. The water light beauty head 3 has the same design.

[0232] Please refer to FIG. 8 again. This embodiment further refines the specific structural design of the first shell 101 .

[0233] The first housing 101 is divided into three main parts: a beauty head connecting portion 1011, a middle portion 1012, and a handheld portion 1013. These three parts are sequentially connected together through a certain connection method (such as integrated molding, screw fixing, etc.), forming the basic framework of the beauty instrument body 1.

[0234] The beauty head connecting portion 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.

[0235] The middle portion 1012, located between the beauty head connection portion 1011 and the handheld portion 1013, features a concave curved surface. This not only adds an elegant aesthetic to the beauty device but, more importantly, provides a natural grip for the user's hand. When the user grips the handheld portion, the concave curved surface perfectly conforms to the user's fingers, providing a more comfortable and stable grip. It is understood that multiple concave curved surfaces can be provided around the middle portion 1012 to accommodate a variety of gripping gestures and meet the diverse gripping habits of different users. Furthermore, the middle portion 1012 acts as a bridge, tightly connecting the beauty head connection portion 1011 and the handheld portion 1013, ensuring the overall structure is stable and durable.

[0236] The handheld portion 1013 is the part that the user directly grasps. It forms an angle with the beauty head connecting portion 1011. Optionally, this angle is set to be less than 180 degrees. Its design should take into account factors such as comfort, anti-slip properties, and portability. It also serves as a support and fixing structure for internal components such as the circuit board 102.

[0237] It should be noted that the beauty head connection portion 1011 and the second shell 201, or the beauty head connection portion 1011 (equivalent to a fixed portion) and the third shell 301 (equivalent to a movable portion) can be combined to form a beauty care portion, which may include a beauty care functional component for skin care. Optionally, the beauty care functional component can be provided on the second shell 201 or the third shell 301. It is understood that the beauty care portion can be designed as a structure in which the beauty head connection portion 1011 and the second shell 201 (or the third shell 301) are fixedly mounted, or can be designed as a structure in which the beauty head connection portion 1011 and the second shell 201 (or the third shell 301) are detachably mounted to each other.

[0238] 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 electrical care device, the beauty instrument can be an ion (or microcurrent, or radiofrequency) beauty instrument; and when the beauty care functional components are both a microneedle device and a spray device, the beauty instrument can be a water light beauty instrument.

[0239] 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.

[0240] When the entire first housing 101 is made of a conductive material, this means that all three components, including the beauty head connection portion 1011, the middle portion 1012, and the handle portion 1013, are also made of conductive materials. This design ensures that the entire beauty device body 1 is conductive, ensuring that electrical conduction is achieved in any position upon contact with the skin of the hand. Furthermore, the all-conductive design enhances the aesthetics and overall appearance of the beauty device, making it appear more high-end and stylish.

[0241] However, a design with all conductive materials may increase costs and manufacturing difficulty. Therefore, in actual production, it may be considered to design only part of the first shell 101 with a conductive material. In this case, there are many possible 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.

[0242] This partially conductive material design can reduce costs and manufacturing difficulty while maintaining a certain degree of conductivity.

[0243] It should be noted that whether choosing a fully conductive material or a partially conductive material design, factors such as safety, conductivity, and durability must be considered. The selection and use of conductive materials should ensure the stability and safety of the beauty device.

[0244] 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.

[0245] Please refer to FIG6 again. In this embodiment, the water light beauty head 3 further includes a third shell 301. The third shell 301 is installed on the first shell 101.

[0246] The water light beauty head 3 also includes a micro needle device 302 and / or a mist device;

[0247] 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 .

[0248] Furthermore, the water light beauty head 3 is also provided with an atomization outlet 303 provided on the third housing 301 for discharging 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 provided near the microneedle device 302. Specifically, the atomization outlet 303 can be designed to surround the microneedle device 302 so as to be close to the microneedle device 302; or, as shown in Figures 6 and 9, the microneedle device 302 is provided with at least one escape hole extending therethrough, which can also serve as the aforementioned mist outlet 312. Of course, the atomization outlet 303 can also be provided side by side with and close to the microneedle device 302. It is understood that the atomization outlet 303 can be provided only near the microneedle device 302, or it can be provided only at a position on the third housing 301 corresponding to the microneedle device 302, and the microneedle device 302 can then provide a corresponding mist outlet 312 connected to the atomization outlet 303.

[0249] 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.

[0250] Microneedle device 302 may include a microneedle wafer or other microneedle form. Microneedle wafer technology is a high-tech medical cosmetic technique. Microneedle wafers, also known as "nano-microneedles" or "wafer microneedles," are made of biocompatible nanoporous silicon material. Their tips are less than 100 nanometers in diameter and penetrate only the stratum corneum, offering enhanced safety. The water-light beauty head 3 utilizes the microneedle wafer to stimulate the skin, creating microscopic channels on the surface that allow nutrients or medications (collectively, essences) to penetrate deep into the skin, achieving a cosmetic effect.

[0251] Since mist essence can be better evenly distributed on the skin than liquid essence, and is easier to penetrate into the skin and be absorbed by the skin, bringing moisturizing 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.

[0252] It is understood that when only the microneedle device 302 or the mist device is installed in the water light beauty head 3, the beauty device can independently perform microneedle penetration enhancement care or atomization supply care. When only single-function care is desired, the user experience and care effect will not be reduced due to the mutual influence between the components that realize different care functions. Although the microneedle device 302 and the mist device can be installed separately, in order to achieve better skin care effects, the water light beauty head 3 can be equipped with both the microneedle device 302 and the mist device. The mist device and the microneedle device 302 can be used in combination. That is, while the microneedle device 302 is used to open deep channels for the skin, the mist device can also provide atomized essence. This allows the essence to penetrate the skin through the skin channels opened by the microneedle device 302 immediately, improving the efficiency and effectiveness of the care. 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. The user can replenish the essence or replace the microneedle device by replacing the water light beauty head, thereby improving the convenience of the user's beauty care and also improving hygiene and safety. If the third housing 301 is non-detachably mounted on the first housing 101, a structure for easily adding essence can be designed on the third housing 301. For example, a liquid filling port can be provided so that the user can directly add essence to the hydrating beauty head 3 through the liquid filling port without removing the hydrating beauty head 3 from the first housing 101.

[0253] Please refer to Figures 7-8 again. In this embodiment, the beauty instrument body 1 further includes an air supply mechanism 8 disposed in the first shell 101;

[0254] The air supply mechanism 8 is electrically connected to the circuit board 102 , and the air supply mechanism 8 is connected to the water light beauty head 3 for delivering gas to the mist outlet device.

[0255] It should be noted that the air supply mechanism 8 plays a crucial role in the implementation of pneumatic atomization. When using negative pressure aspiration atomization, the gas flow path provided by the air supply mechanism 8 is isolated from the essence flow path. The purpose is to use high-speed gas to generate negative pressure at the outlet of the essence flow path, which can draw the essence out of the flow path and combine with the essence to transform the essence into a small molecule mist, thereby achieving atomization of the essence.

[0256] When high-pressure air atomization is used, the flow path of the gas provided by the air supply mechanism 8 is connected to the flow path of the essence, and at the end, the gas and the essence will share a flow path, aiming to achieve atomization of the essence by utilizing high-speed gas to spray the essence in the same flow path into tiny droplets.

[0257] 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.

[0258] 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 inside the hyaluronic acid beauty head 3, the structure of the hyaluronic acid beauty head 3 will be very complex and the volume will be large, the design difficulty will increase, and the reliability will also 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 cost of discarding 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 inside 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 cost of discarding.

[0259] Exemplarily, the air supply mechanism 8 may be an air pump.

[0260] 9-11 , in this embodiment, the mist outlet device further includes a gas flow channel 304 and a liquid flow channel 305 provided in the third housing 301 ;

[0261] A liquid outlet 306 is provided at one end of the liquid flow channel 305;

[0262] An air inlet 307 is provided at one end of the gas flow channel 304, and an air outlet 308 is provided at the other end of the gas flow channel 304. The air inlet 307 is connected to the air supply mechanism 8, and the air outlet 308 is provided near the liquid outlet 306. For example, the air outlet 308 is provided around part or all of the liquid outlet 306. As shown in FIG10 , the air outlet 308 is annular and provided around the liquid outlet 306. Alternatively, the air outlet 308 includes one or more air outlets and is provided around the liquid outlet 306. Alternatively, the air outlet 308 is provided side by side with the liquid outlet 306. Alternatively, the liquid outlet 306 is provided around part or all of the air outlet 308. Alternatively, the liquid outlet 306 includes one or more air outlets and is provided around the air outlet 308.

[0263] It should be noted that, in this embodiment, the third shell 301 is provided with an atomizing bin 321, a mist outlet device, which can also be called 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 air outlet 308 are arranged on 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 air 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 integral whole, it is the first design of the atomization chamber 321 of this embodiment.

[0264] Furthermore, it should be noted that the third housing 301 and the mist dispensing device constitute at least part of the essence bottle, with the third housing 301 acting as the body of the essence bottle. The mist dispensing device and the third housing 301 can be combined to form an atomizing device, and the air supply mechanism 8, the mist dispensing device, and the third housing 301 can be combined to form a pneumatic atomizing device.

[0265] 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 a 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 out to reach the human face.

[0266] 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, stimulating collagen proliferation and cell regeneration, and repairing 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.

[0267] 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 as to achieve a uniform and soft atomization effect. 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 as to increase the atomization speed. 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 as to expand the atomization area and atomization flow rate as much as possible while ensuring a high atomization speed.

[0268] Specifically, when the gas outlet 308 surrounds part or all of the liquid outlet 306, or when multiple gas outlets 308 are arranged along the periphery of the liquid outlet 306, the gas surrounds the essence, creating a "gas surround" effect, allowing the essence to be more evenly encapsulated and atomized. This approach ensures that the essence is fully atomized, thereby improving its permeability and utilization rate. Furthermore, due to the gas surround effect, the essence atomization process is gentler and less irritating to the skin.

[0269] 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.

[0270] When the liquid outlet 306 is arranged around some or all of the gas outlet 308, or when multiple gas outlets 308 are arranged around the liquid outlet 306, the essence can flow toward the gas outlet 308 from multiple directions, increasing the amount of essence flowing out per unit time and the contact area between the essence and the gas. This design not only ensures that more essence flows out and is fully atomized, but also achieves a uniform atomization effect over a wider area.

[0271] In the actual production process, the appropriate layout can be selected according to specific needs and product characteristics to achieve the best atomization effect.

[0272] In this embodiment, the distance between the liquid outlet 306 and the gas outlet 308, and / or the ratio of their areas, must meet certain misting conditions, which affect the misting effect. By properly designing these two parameters, the misting device can ensure that it can produce a uniform and delicate atomization effect, thereby improving skin care effects and user experience.

[0273] Optionally, the distance between the liquid outlet 306 and the air outlet 308 can be set within a range. For example, the distance between the liquid outlet 306 and the air outlet 308 can be 0.01mm, 0.25mm or 0.5mm. Optionally, the distance range between the liquid outlet 306 and the air 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 air outlet 308 can be set to 0.01mm; when the required mist output is medium, the distance between the liquid outlet 306 and the air outlet 308 can be set to 0.25mm; when the required mist output is small, the distance between the liquid outlet 306 and the air outlet 308 can be set to 0.5mm.

[0274] It's important to note that this spacing determines the contact method and speed between the serum and the gas. If the spacing is too large, the serum and gas may not fully contact and mix, resulting in poor atomization. If the spacing is too small, the serum and gas may mix too quickly, also affecting atomization. Therefore, this spacing range is designed to ensure that the serum and gas mix at the appropriate speed and distance for efficient atomization.

[0275] 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.

[0276] 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 remain within this ratio. This ratio determines the degree of mixing between 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 may cause the essence to not be fully atomized and produce droplets. Therefore, this ratio range is to ensure that the essence and gas can be evenly and fully mixed, thereby producing an ideal atomization effect.

[0277] Please refer to Figures 9 and 25 again. In this embodiment, further, for the design with 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 306 passes through the liquid outlet part 318. An air outlet cavity 320 is provided between the socket part 319 and the liquid outlet part 318. The air outlet cavity 320 is connected to the gas flow channel 304. The air outlet 308 is formed at the end of the air outlet cavity 320 away from the gas flow channel 304.

[0278] It should be noted that the design of the air outlet cavity 323 is more conducive to uniform airflow at the air outlet 308 .

[0279] In this embodiment, the design of the beauty instrument is further expanded and improved.

[0280] Regarding the design of the liquid storage structure, please refer again to Figures 9-11 and in combination with Figure 22. In the first embodiment, a liquid storage cavity 309, also referred to as a liquid storage tank, is further provided in the third housing 301. The liquid storage cavity 309 is used to store the essence.

[0281] A liquid inlet 310 is provided at the other end of the liquid flow channel 305, and the liquid inlet 310 is connected to the liquid storage chamber 309, as shown in Figure 22.

[0282] It should be noted that this embodiment provides a certain storage space for the essence by setting a liquid storage chamber 309 in the third shell 301, 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.

[0283] 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.

[0284] It is understandable that if the water light beauty head 3 is designed for liquid replenishment, in order to facilitate the replenishment of essence into the liquid storage chamber 309, a liquid replenishment port connected to the liquid storage chamber 309 is further opened on the third shell 301.

[0285] Please refer to Figures 8-9 again. In this embodiment, further, the gas flow channel 304 surrounds part or all of the liquid flow channel 305;

[0286] The liquid storage chamber 309 surrounds part or all of the liquid flow channel 305 .

[0287] 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 outlet volume and gas outlet speed. The gas flow channel 304 needs to be arranged around the liquid flow channel 305. On the one hand, it can be around part of the liquid flow channel 305, and on the other hand, it can be around the entire liquid flow channel 305. As shown in Figure 23, 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.

[0288] Figure 9 illustrates a situation where gas flow channel 304 partially surrounds liquid flow channel 305. In this case, one gas flow channel 304 can surround a portion of liquid flow channel 305, or at least two gas flow channels 304 can surround a portion of liquid flow channel 305. The number and shape of gas flow channels 304 can be specifically set according to actual needs. In Figure 9, the number of gas flow channels 304 is set to two, and the shape is symmetrical and quasi-crescent. Correspondingly, in Figures 10-11, the number of gas outlets 308 and gas inlet 307 are also set to two symmetrically, and the shape is quasi-crescent.

[0289] It should also 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, the liquid storage cavity 309 can surround part of the liquid flow channel 305, or it can surround the entire liquid flow channel 305. The liquid storage cavity 309 surrounding the entire liquid flow channel 305 can provide a larger liquid storage space.

[0290] 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:

[0291] First, the first housing 101 generally 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 the need for frequent replenishment of essence.

[0292] Secondly, from the perspective of maintaining and replenishing the essence, placing the liquid reservoir 309 within the first housing 101 may be more convenient. Users may find it easier to access and operate the liquid reservoir 309 located in the first housing 101, especially when replenishing or replacing the essence. This design takes user convenience into consideration and simplifies maintenance.

[0293] Regarding the design of the liquid storage structure, please refer to Figures 12-15 again. 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.

[0294] 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 the essence, but directly stores the essence in the liquid flow channel 305 .

[0295] 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 non-liquid replenishment design, or it can be a design with a liquid inlet 310 but the liquid inlet 310 can be blocked, which corresponds to a liquid replenishment design.

[0296] 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 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, as shown in Figure 14.

[0297] In addition, it should be noted that the gas flow channel 304 and the liquid flow channel 305 are isolated from each other;

[0298] The liquid flow channel 305 passes through one end of the main body 322 to form a liquid flow channel outlet;

[0299] The gas flow channel 304 passes through the opposite ends of the main body 322 to form a gas flow channel outlet and a gas flow channel inlet respectively;

[0300] The gas flow channel outlet and the liquid flow channel outlet are disposed at the same end of the main body 322 .

[0301] Furthermore, the liquid inlet 310 is provided at an end of the main body 322 away from the outlet of the liquid flow channel.

[0302] Please refer to FIG. 13 and FIG. 15 again. In this embodiment, further, the liquid flow channel 305 can be arranged in a straight direction or in a circuitous manner.

[0303] Exemplarily, when the liquid flow channel 305 is arranged straight, the liquid flow channel 305 includes a liquid sub-flow channel (52);

[0304] The liquid sub-channel (52) is arranged straight;

[0305] 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);

[0306] Several liquid sub-flow channels (52) are connected end to end in sequence to form a tortuous shape.

[0307] It should be noted that the term "tortuous" refers to the design of the liquid flow channel 305 being not linear but rather having multiple bends, turns, or curves. As shown in FIG13 , the essence will flow from port a at one end of one 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, then from port c through that liquid flow channel 305 to the other end of the liquid flow channel 305, and so on. Compared to a liquid flow channel 305 extending straight from the liquid inlet 310 to the liquid outlet 306 of the liquid flow channel 305, the tortuous design can increase the length and storage space of the liquid flow channel 305, thereby increasing the storage capacity of the essence, thereby extending the use time of the water light beauty head 3 and reducing the frequency of beauty head replacement or refilling.

[0308] Please refer to Figures 6 and 9 again. In this embodiment, further, the microneedle device 302, the liquid outlet 306, and the air 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 set near the position where atomization is formed on the beauty instrument (i.e., the liquid outlet 306 and the air outlet 308). When using the product, the skin area acted by the microneedle device 302 and the essence atomized particles at least partially overlap, thereby improving care efficiency.

[0309] It should be noted that there are two possible designs for the relative positional relationship between the microneedle device 302 and the liquid outlet 306 and the gas outlet 308 .

[0310] 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.

[0311] In a second design, they can also be arranged spatially in a stacked manner. This means that the microneedle device 302 is located in the direction of mist discharge and is stacked with the liquid outlet 306 and the gas outlet 308 in the direction of mist discharge. This design can make more compact use of space, reduce the overall size, and may make certain internal connections and layouts more concise. This embodiment takes the second design as an example, as shown in Figures 6 and 9.

[0312] Please refer to Figures 8-9 again. In this 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 air outlet 308 and the end of the third shell 301 facing the first shell 101. That is, the air 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 air outlet 308.

[0313] 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.

[0314] Please refer to Figures 6, 9 and 16 again. 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.

[0315] In this embodiment, the third housing 301 includes a first portion 3011 and a second portion 3012 connected to each other, as shown in FIG16 ;

[0316] The liquid outlet 306 and the gas outlet 308 are provided in the first portion 3011;

[0317] The microneedle device 302 is mounted on the second portion 3012;

[0318] The second part 3012 covers the liquid outlet 306 and the air outlet 308, and is provided with an atomization outlet 303 corresponding to the liquid outlet 306 or the air outlet 308. The microneedle device 302 is provided with an avoidance hole at the position corresponding to 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.

[0319] 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 skin care efficiency.

[0320] Optionally, a bypass hole is located at the center of the microneedle device 302 and is coaxially arranged with the atomization outlet 303. This ensures that the mist generated by the atomization chamber 321 can be discharged directly through the bypass hole on the microneedle device 302. This more effectively utilizes the fine channels formed by the microneedles in the skin, allowing the essence in the mist to penetrate deeper into the skin, enhancing the beauty effect. Furthermore, the integration of the mist outlet 312 and the microneedle device 302 makes the entire device more compact and easier to operate.

[0321] Furthermore, in other embodiments, the mist outlet 312 may also be disposed close to the microneedle device 302 .

[0322] It should be noted that the mist outlet 312 is located near the microneedle device 302, but is not directly integrated with the microneedle device 302. This design can maintain the independence of the microneedle device 302 and facilitate replacement or cleaning.

[0323] Regardless of the design chosen, multiple factors must be considered, including user convenience, device cleaning and maintenance, and serum penetration. In this embodiment, by cleverly designing the relationship between the microneedle device 302 and the mist outlet 312, the serum bottle ensures effective serum penetration while providing a good user experience, achieving a perfect combination of cosmetic effects and operational convenience.

[0324] 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, this 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. This ensures 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). This can reduce the discomfort caused by the microneedles on the microneedle device 302 irritating the skin to a large extent, thereby improving the user experience.

[0325] Please refer to Figure 7 again. In this embodiment, the beauty instrument body 1 further includes a driving mechanism 7 arranged in the first shell 101. 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.

[0326] Since the mesotherapy beauty 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 beauty 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 beauty head 3, that is, the mesotherapy beauty 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 beauty head 3 will return under the action of the elastic reset member, thereby realizing reciprocation. At this time, the reciprocating driving device includes the driving device 701 and the elastic reset member.

[0327] Exemplarily, the elastic return member may be a spring.

[0328] 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.

[0329] In addition, similarly, when setting the driving mechanism 7, it is taken into consideration that if the driving mechanism 7 is set inside the hyaluronic acid beauty head 3, the structure of the hyaluronic acid beauty head 3 will be very complex and the volume will be large, the design difficulty will increase, and the reliability will also 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 cost of discarding 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 inside the beauty instrument body 1 to reduce the structural complexity of the hyaluronic acid beauty head 3 and reduce the cost of discarding.

[0330] Please refer to Figures 7-8 again, and in combination with Figure 16, in this embodiment, further, the air inlet 307 is connected to the air supply mechanism 8 through the air hose 9.

[0331] 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 air 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 air supply mechanism 8 by a gas hose 9 with good flexibility to improve the structural reliability and durability, thereby ensuring a stable gas supply.

[0332] Please refer to FIG. 16 again, and refer to FIG. 20-21 . In this embodiment, further, a connecting assembly 702 is provided in the first housing 101 .

[0333] The driving mechanism 7 includes a driving device 701;

[0334] 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 ;

[0335] It should be noted that the drive device 701 serves as the core power source and is electrically connected to the circuit board 102 to provide stable and continuous power output. It can be precisely controlled according to user needs or preset programs to ensure that the water light beauty head 3 moves at an appropriate speed and force.

[0336] Connecting assembly 702 connects the drive unit 701 and the hydrating head 3. One end of the connecting assembly 702 connects to the third housing 301, ensuring accurate power transmission to the hydrating head 3. The other end connects to the drive unit 701, ensuring a stable connection between the power source and the moving parts. This connection not only ensures efficient power transmission but also makes replacement and maintenance of the hydrating head 3 much easier and faster.

[0337] In this embodiment, the driving device 701 further 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;

[0338] The connecting assembly 702 is eccentrically connected to the output shaft 703 of the driving device 701;

[0339] The first direction is perpendicular to the reciprocating motion direction of the microneedle device 302;

[0340] The second direction is the reciprocating direction of the microneedle device 302 .

[0341] Illustratively, 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.

[0342] It should be noted that the horizontal arrangement of the driving device 701 in the direction perpendicular to the reciprocating motion of the microneedle device 302 reduces the space utilization of the driving mechanism 7 in the direction of motion of the microneedle device 302, and is also beneficial to the arrangement of other components in the first shell 101 in the direction perpendicular to the linear reciprocating motion 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.

[0343] 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.

[0344] Please refer to Figures 16 and 20-21 again. In this embodiment, the connecting assembly 702 further includes a connecting piece 7022. The gas supply mechanism 8 is connected to the mist outlet device through the connecting piece 7022, and is used to deliver gas to the mist outlet device through the connecting piece 7022.

[0345] The driving mechanism 7 is connected to the connecting member 7022 and is used to drive the connecting member 7022 to move, thereby driving the third housing 301 to move;

[0346] 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.

[0347] The connecting member 7022 includes a first sleeve portion 70221 and a connecting portion 70222 connected to each other;

[0348] The third housing 301 is inserted into the first socket portion 70221;

[0349] The output shaft 703 is connected to the connecting portion 70222;

[0350] Specifically, the first sleeve portion 70221 is used to conveniently connect to the third housing 301. 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.

[0351] Connecting portion 70222 is responsible for connecting to output shaft 703. Output shaft 703, serving as the power output of drive device 701, is tightly connected to connector 7022 via connecting portion 70222, ensuring stable transmission of driving force. This connection ensures efficient transmission of driving force and also makes the movement of the entire drive mechanism 7 more stable and controllable.

[0352] Please refer to Figures 16 and 20-21 again. In this embodiment, the connecting assembly 702 further includes an eccentric wheel 7021;

[0353] The connecting member 7022 further includes a second sleeve portion 70223 , and the first sleeve portion 70221 , the connecting portion 70222 and the second sleeve portion 70223 are connected in sequence;

[0354] 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 .

[0355] It should be noted that due to the presence of the eccentric wheel 7021, when the drive device 701 drives the eccentric wheel 7021 to rotate via the output shaft 703, the eccentric wheel 7021 drives the connecting member 7022 to reciprocate along a straight line. As a result, the water light beauty head 3, driven by the connecting member 7022, repeatedly contacts and leaves the user's face, achieving a beauty action. In addition, the third housing 301, the eccentric wheel, and the connecting member 7022 are all connected in a sleeve manner, which can increase the mutual contact area, thereby improving the connection stability and further ensuring the stability of the driving movement.

[0356] 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 the vibration generated when the driving device 701 rotates on the beauty instrument and user experience, while also improving structural reliability and durability.

[0357] In this embodiment, further, the gas delivery hose 9 crosses the second sleeve portion 70223 and is connected to the connector 7022 , and the gas delivery hose 9 is communicated with the mist outlet device through the connector 7022 .

[0358] Specifically, the gas hose 9 is designed to span the second sleeve portion 70223 and connect to the connector 7022. This layout effectively utilizes the space above the second sleeve portion 70223 while allowing the gas hose 9 to fit snugly against the connector 7022, reducing the possibility of gas leakage due to hose loosening or displacement. Furthermore, the design of spanning the second sleeve portion 70223 also allows the gas hose 9 to better withstand the tensile forces during exercise, improving its durability and stability.

[0359] In this embodiment, further, the height of the driving mechanism 7 in its axial direction is not greater than the maximum width of the first sleeve portion 70221 in a direction parallel to the axial direction of the driving mechanism 7; and / or,

[0360] 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 .

[0361] 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, avoiding other components in the beauty instrument except the driving mechanism 7 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.

[0362] 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.

[0363] 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.

[0364] Specifically, the L-shaped structure optimizes spatial layout, allowing connector 7022 to occupy a relatively small volume in three-dimensional space. Furthermore, the provision of the escape space fully considers the size and installation requirements of drive device 701. By placing drive device 701 within the escape space, it avoids requiring additional space and spatial conflicts with other components, thereby ensuring stable and reliable operation.

[0365] This design also helps reduce the size and weight of the entire beauty device, making it easier to carry and use, meeting the demand for miniaturization and portability. At the same time, the compact structure also makes the connections between components more stable, improving the stability and durability of the entire device.

[0366] Please refer to Figures 7-8, 16 and 20 again. In this embodiment, further, the air inlet 307 of the gas flow channel 304, the first sleeve portion 70221 and the air supply mechanism 8 are connected in sequence.

[0367] It should be noted that the third shell 301 is detachably fixed in the first socket portion 70221, that is, there is a first socket portion 70221 between the air inlet 307 of the gas flow channel 304 and the air supply mechanism 8. In this way, it can be understood that the first socket portion 70221 is provided with a conducting hole, through which the air inlet 307 of the gas flow channel 304 and the air supply mechanism 8 are connected, so that the air supply mechanism 8 can smoothly transport the gas to the air inlet 307 of the gas flow channel 304.

[0368] 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.

[0369] Please refer to FIG16 again. In this embodiment, a first sealing member is provided at the position where the pneumatic atomizing device communicates with the air supply mechanism 8. The first sealing member is the sealing ring 10 in FIG16.

[0370] Specifically, a sealing ring 10 is provided between the third housing 301 and the first sleeve portion 70221;

[0371] Alternatively, a sealing ring 10 is provided between the third shell 301 and the air supply mechanism 8 .

[0372] It should be noted that in order to ensure that the gas coming out of the gas supply mechanism 8 will 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 air leakage.

[0373] It is understandable that the same applies to the sealing ring 10 provided between the third shell 301 and the air supply mechanism 8 .

[0374] 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;

[0375] 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 .

[0376] 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 likely 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 set 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.

[0377] It can be understood that the sealing ring 10 is sleeved on the outer periphery of the portion of the third shell 301 connected to the air supply mechanism 8 in the same manner.

[0378] Please refer to FIG9 again. In this embodiment, further, the liquid storage chamber 309 is arranged around the atomization bin 321. Two second sealing members 18 are spaced apart between the outer wall of the atomization bin 321 and the outer wall of the liquid storage bin. The liquid inlet 310 is located between the two second sealing members 18.

[0379] Alternatively, a second sealing member 18 is sleeved on the outer circumference of the liquid inlet 310 .

[0380] It should be noted that the liquid inlet 310 is provided in the atomization chamber 321 and communicates with the liquid storage chamber 309, so that the liquid in the liquid storage chamber 309 flows into the atomization chamber 321 for atomization. The position and size design of the liquid inlet 310 are very critical, which directly affects the flow rate of the liquid and the atomization effect.

[0381] 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 configurations:

[0382] In a first possible configuration, the liquid storage chamber 309 is disposed around the atomization chamber 321, as shown in FIG9 :

[0383] In this case, two second sealing members 18 are spaced apart between the outer wall of the atomizing chamber 321 and the outer wall of the liquid storage chamber 309, and the liquid inlet 310 is located between the two sealing members. This design prevents liquid from leaking outward when it flows from the liquid storage chamber 309 to the atomizing chamber 321 due to the obstruction of the two sealing members.

[0384] 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.

[0385] 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.

[0386] Please refer to FIG. 9 again. In this embodiment, further, the liquid inlet 310 is opened at a position corresponding to the bottom position of the liquid storage cavity 309 .

[0387] It should be noted that, as mentioned above, the structural design of the first shell 101 conforms to ergonomics, that is, when the user uses the mesotherapy beauty instrument, the mesotherapy 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 position corresponding to the bottom position of the liquid storage chamber 309 can more easily drain 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.

[0388] 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 towards the lowest liquid level of the essence.

[0389] Specifically, the third housing 301 is provided with a foolproof structure;

[0390] An accommodating 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 accommodating space.

[0391] Please refer to Figures 17-19. In this embodiment, the water light beauty head 3 further includes a protective cover 313;

[0392] The protection cover 313 is disposed on the position of the third housing 301 corresponding to the microneedle device 302 .

[0393] It should be noted that by providing the protective cover 313, when the mesotherapy beauty head 3 is idle, especially when the mesotherapy beauty head 3 is removed from the beauty instrument body 1 and placed, the microneedle device 302 can be protected from contact 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 of the beauty effect being adversely affected by the outside world.

[0394] 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 .

[0395] In one embodiment, a silicone pad 314 may be disposed inside the protective cover 313 .

[0396] 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.

[0397] 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.

[0398] Please refer to Figures 18-19 again. In this embodiment, further, an anti-blocking member 315 is provided in the protective cover 313;

[0399] The anti-blocking member 315 passes through the atomizing outlet 303 and is inserted into the liquid outlet 306 .

[0400] 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 residue in the liquid outlet 306, the essence remaining in the liquid outlet 306 is easy to cause clogging of the liquid outlet 306 after drying. Once blocked, it not only affects 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 residue of essence in the liquid outlet 306; when 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 solidified material remaining in the liquid outlet 306 can also be taken out, thereby reducing the accumulation of solidified material of the essence and reducing the possibility of clogging of the liquid outlet 306.

[0401] Please refer to Figures 18-19 again, and in combination with reference Figure 25, in this embodiment, further, a first limiting structure 15 is provided on the inner side of the protective cover 313. 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 component 315 inserted into the liquid outlet 306.

[0402] It should be noted that simply inserting and removing the anti-blocking member 315 for adjustment is not sufficient. Without an effective stop mechanism, the anti-blocking member 315 may be inserted too deeply into the liquid outlet 306, which may lead to adverse consequences, such as damaging the structure of the liquid outlet or making it difficult to remove the anti-blocking member 315.

[0403] To solve this problem, this 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 acts as a block or stop, limiting the anti-blocking member 315 from further entering the liquid outlet 306.

[0404] In this way, the first limiting structure 15 ensures that the anti-blocking member 315 has an appropriate depth when inserted into the liquid outlet 306, which can not only play its anti-blocking function but also prevents it from being inserted too deeply and causing other problems. This increases the reliability and safety of the device and also makes operation easier and more accurate.

[0405] Please refer to Figures 18-19 and Figure 25 again. In this embodiment, further, the first limiting structure 15 is provided on the peripheral side of the anti-blocking member 315 away from one end of the protective cover 313, and an avoidance space is formed between the first limiting structure 15 and the anti-blocking member 315.

[0406] 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 sides of the gas outlet 308 and the liquid outlet 306. The gas outlet 308 and the liquid outlet 306 are then directly opposite the avoidance space, preventing the gas outlet 308 and the liquid outlet 306 from being damaged by interference from the first limiting structure 15, thereby affecting the mist discharge function. This 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, providing sufficient space for the liquid outlet 306 and the gas outlet 308, and ensuring the stability and reliability of the entire structure.

[0407] Please refer to Figures 18-19 again. 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.

[0408] 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 .

[0409] 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.

[0410] Please refer to Figures 6, 9 and 18 again. In this embodiment, the microneedle device 302 is further provided between the protective cover 313 and the liquid outlet 306. The water light beauty head 3 is provided with an atomization outlet 303, which is connected to the liquid outlet 306;

[0411] The microneedle device 302 has 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 .

[0412] 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 out from the atomization outlet 303 and the mist outlet 312 in turn, and finally reach the skin stimulated by the microneedle device 302.

[0413] 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.

[0414] Please refer to FIG. 9 again. In this embodiment, 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 .

[0415] 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 .

[0416] It should be noted that, first of all, the purpose of providing the air pressure regulating hole 316 in both the liquid reservoir 309 and the liquid flow channel 305 is to regulate the internal air pressure. During operation of the beauty device, the air pressure within the liquid reservoir 309 or the liquid flow channel 305 may decrease as the essence is consumed, thereby affecting the essence supply. To maintain stable air pressure, a method is required to balance the internal and external pressure differences, and the air pressure regulating hole 316 fulfills this role.

[0417] Specifically, the air pressure regulating hole 316 can be located away from the lowest level of the essence. Furthermore, the air-permeable liquid barrier 317 provided within the air pressure regulating hole 316 allows air to pass through while preventing the essence from leaking. Specifically, the air-permeable liquid barrier 317 can be made of a material that is air-permeable but liquid-impermeable, such as a special porous material or film. This allows air to flow freely through the air pressure regulating hole 316, thereby balancing the air pressure inside and outside the liquid reservoir 309 or liquid flow channel 305. The essence, however, is blocked by the air-permeable liquid barrier 317 and prevents it from leaking out of the air pressure regulating hole 316.

[0418] The design of the air pressure regulating hole 316 and the air-permeable liquid-blocking member 317 stabilizes the air pressure within the liquid reservoir 309 or liquid flow channel 305, while also preventing accidental leakage of the essence. This not only enhances the stability and safety of the beauty device, but also provides users with a more comfortable and secure skincare experience.

[0419] 1-6 , an embodiment of the present application provides a multi-purpose beauty instrument, including a beauty instrument body 1, a first beauty head 2, and a second beauty head 3. Regarding the connection between the first beauty head 2 and the second beauty head 3 and the beauty instrument body 1, there are two possible implementations:

[0420] In the first embodiment, the first beauty head 2 and the second beauty head 3 are each detachably connected to the beauty device body 1 via a first fixing structure. This design simplifies the replacement of the two beauty heads, requiring only the same operation. Furthermore, the unified fixing structure reduces manufacturing costs.

[0421] In a second embodiment, the second beauty head 3 is detachably connected to the beauty device body 1 via a first fixing structure, while the first beauty head 2 is detachably connected to the beauty device body 1 via a different second fixing mechanism. This design provides more connection options, making the beauty device more flexible to assemble. Furthermore, different fixing mechanisms can be selected to connect the beauty heads according to different beauty needs, making the beauty device more adaptable to various scenarios. For example, software or hardware design can be used to identify different beauty head types based on different fixing structures or connection methods.

[0422] It should be noted that in order to meet people's demand for multifunctional beauty devices, this embodiment proposes a detachable beauty device design. This design concept aims to achieve multi-purpose use of one device and provide users with a more flexible and convenient beauty care experience.

[0423] Traditional, non-detachable beauty devices often rely on a single function due to their monolithic design, preventing users from selecting and adjusting the device to suit their skincare needs. This not only limits the device's scope of use but also prevents users from finding targeted solutions to their diverse skincare needs.

[0424] To address this issue, this embodiment conducted in-depth research and discussion, ultimately proposing a design solution that improves the beauty device to a detachable structure. Specifically, the beauty device is divided into two parts: the beauty device body 1 and a detachable beauty head. This design allows the beauty head to be removed at any time as needed, making it convenient for users to select the appropriate beauty head for their skincare needs.

[0425] In this embodiment, the first beauty head 2 and the second beauty head 3 are two different types of beauty heads. For example, the first beauty head 2 can be a beauty head that requires a conductive connection (such as an iontophoresis beauty head with microcurrent beauty functions, a hair removal beauty head with photothermal hair removal functions, etc.), while the second beauty head 3 can be a beauty head that does not require a conductive connection (such as a water-based beauty head with minimally invasive penetration beauty functions). To facilitate a better understanding of the solution provided by this embodiment, this embodiment will be described in detail using the example of the first beauty head 2 being an iontophoresis beauty head and the second beauty head 3 being a water-based beauty head.

[0426] In the beauty field, the design and application of various beauty devices aim to satisfy people's pursuit of beauty and health. Among them, iontophoresis beauty devices and hyaluronic acid beauty devices are two devices that have attracted much attention. Although the principles and applications of these two devices are slightly different, their core goal is to provide the skin with necessary nutrients and moisture through specific technical means, thereby achieving a beautiful effect.

[0427] For example, when users need deep cleansing or ion permeation, they can choose to install the ion introduction and export beauty head; when moisturizing or nutrition infusion is needed, they can choose to install the water light beauty head. This detachable design not only improves the practicality of the beauty device, but also makes it easier for users to use it.

[0428] Furthermore, to ensure ease of installation and use, this embodiment optimizes the mounting position during the design process. Through precise sizing and structural design, this embodiment ensures that the beauty head can be quickly and accurately installed on the beauty instrument body 1, while also ensuring stability and reliability during use.

[0429] In short, this detachable beauty instrument design provides users with a brand-new beauty care experience. It not only makes the beauty instrument have multiple functions to meet different skin care needs, but also enhances the user experience through the humanized design concept.

[0430] It is understood that when the first beauty head 2 shown in Figures 4 and 5 is mounted on the beauty device body 1 shown in Figure 3, the assembled beauty device becomes an iontophoresis beauty device, the appearance of which is shown in Figure 1. When the second beauty head 3 shown in Figure 6 is assembled on the beauty device body 1 shown in Figure 3, a water-light beauty device is obtained, the appearance of which is shown in Figure 2.

[0431] In this embodiment, further, one of the beauty instrument body 1 and the beauty head is provided with a mounting position 4 , and the other can be inserted into the mounting position 4 .

[0432] It should be noted that the design of mounting position 4 ensures a secure and reliable connection between the beauty head and the beauty device body 1. When the beauty head or the beauty device body 1 is inserted into mounting position 4, the contact area and interference area between the two are increased, thereby providing better stability and support. This helps to prevent the beauty device from falling off during use, ensuring safe use.

[0433] Although this embodiment limits the installation position 4 to be provided on the beauty instrument body 1 or on the beauty head, in general, the installation position 4 is preferably provided on the beauty instrument body 1 which is larger and has more space for layout, as shown in FIG3 .

[0434] In this embodiment, further, in the case where the first beauty head 2 and the second beauty head 3 are detachably connected to the beauty instrument body 1 via the first fixing structure, the first fixing structure may include a clamping block 25 and a clamping groove 26 that cooperates with the clamping block 25;

[0435] The inner wall of the mounting position 4 is provided with a snap-fit ​​block 25, and the outer wall of the portion where the beauty instrument body 1 or the beauty head (i.e., the first beauty head 2 and the second beauty head 3) is inserted into the mounting position 4 is provided with a snap-fit ​​groove 26; alternatively, the inner wall of the mounting position 4 is provided with a snap-fit ​​groove 26, and the outer wall of the portion where the beauty instrument body 1 or the beauty head (i.e., the first beauty head 2 and the second beauty head 3) is inserted into the mounting position 4 is provided with a snap-fit ​​block 25.

[0436] To facilitate a better understanding of the solution provided by this embodiment, the following describes in detail the solution provided by this embodiment by taking the example of providing a mounting position 4 on the beauty instrument body 1, and inserting the iontophoresis and derivation beauty head 2 and the water light beauty head 3 into the mounting position 4.

[0437] At this time, the first aspect may be, referring again to FIG. 4 and FIG. 6 , and in conjunction with FIG. 7 , a snap-fit ​​block 25 is provided on the inner wall of the mounting position 4 , a snap-fit ​​groove 26 is provided on the outer wall of the portion of the first beauty head 2 inserted into the mounting position 4 , and a snap-fit ​​groove 26 is provided on the outer wall of the portion of the second beauty head 3 inserted into the mounting position 4 ;

[0438] The second aspect may be that a snap-fit ​​groove 26 is provided on the inner wall of the mounting position 4 , a snap-fit ​​block 25 is provided on the outer wall of the portion where the first beauty head 2 is inserted into the mounting position 4 , and a snap-fit ​​block 25 is provided on the outer wall of the portion where the second beauty head 3 is inserted into the mounting position 4 .

[0439] It should be noted that the descriptions of the above two aspects both involve the relationship between the first beauty head 2 , the second beauty head 3 and the mounting position 4 , but the difference between them lies in the positions of the snap-fit ​​block 25 and the snap-fit ​​groove 26 .

[0440] In the first aspect, the engaging blocks 25 are provided on the inner wall of the mounting position 4, while the engaging grooves 26 are provided on the outer walls of the first and second beauty heads 2 and 3. This means that when the first and second beauty heads 2 and 3 are inserted into the mounting position 4, their engaging grooves 26 will mate with the engaging blocks 25 in the mounting position 4, thereby achieving a stable connection.

[0441] In the second aspect, the engaging groove 26 is provided on the inner wall of the mounting position 4, while the engaging block 25 is provided on the outer wall of the first beauty head 2 and the second beauty head 3. In this case, when the first beauty head 2 and the second beauty head 3 are inserted into the mounting position 4, their engaging blocks 25 will mate with the engaging groove 26 in the mounting position 4, thus achieving a stable connection.

[0442] It should be noted that although the descriptions of the first and second aspects differ slightly, their core concept is the same: the first and second beauty heads 2 and 3 are stably connected by the matching of the snap-fit ​​block 25 and the snap-fit ​​groove 26. Therefore, in actual application, the appropriate solution can be selected based on specific needs and design requirements.

[0443] In the case where the first beauty head 2 and the second beauty head 3 are detachably connected to the beauty instrument body 1 via the first fixing structure, in this embodiment, the first fixing structure may further include an internal thread and an external thread matching the internal thread;

[0444] The inner wall of the installation position 4 is provided with an internal thread, and the outer wall of the beauty instrument body 1 or the part of the beauty head inserted into the installation position 4 is provided with an external thread.

[0445] It should be noted that this threaded connection is easy to operate and disassemble. The user simply rotates the beauty head to easily connect or disconnect it from the beauty instrument body 1. This design not only improves the user experience but also facilitates daily maintenance and cleaning.

[0446] At the same time, since the matching of the internal thread and the external thread has high precision requirements, this also ensures that the connection between the beauty head and the beauty instrument body has good sealing, which can effectively prevent liquid or dust from entering the connection part, thereby ensuring the safety and hygiene of the beauty instrument.

[0447] In the case where the second beauty head 3 is detachably connected to the beauty instrument body 1 via the first fixing structure, and the first beauty head 2 is detachably connected to the beauty instrument body 1 via the second fixing mechanism, in this embodiment, the first fixing structure may include a clamping block 25 and a clamping groove 26 that is clamped and matched with the clamping block 25; the second fixing structure may include a first magnetic attraction component 27 and a second magnetic attraction component 28 that is mutually attracted to the first magnetic attraction component 27;

[0448] The second beauty head 3 is detachably connected to the beauty instrument body 1 through the first fixing structure, which is the same as the above-mentioned situation in which the first beauty head 2 and the second beauty head 3 are detachably connected to the beauty instrument body 1 through the first fixing structure, and will not be repeated here.

[0449] As for the case where the first beauty head 2 is detachably connected to the beauty instrument body 1 through the second fixing mechanism, specifically, you can refer to 6-7 again and combine it with reference to Figures 26-27. A first magnetic component 27 can be set on the beauty instrument body 1, and a second magnetic component 28 can be set on the first beauty head 2. The setting of the first magnetic component 27 and the second magnetic component 28 not only realizes the assembly connection between the beauty instrument body 1 and the first beauty head 2, but also provides a more convenient disassembly experience.

[0450] Referring again to Figures 26-27, in this embodiment, the first magnetic attraction component 27 includes a first magnet 2701 and a second magnet 2702. The first magnet 2701 and the second magnet 2702 are disposed on the beauty device body 1 in a spaced-apart manner, and the polarities of the first magnet 2701 and the second magnet 2702 are opposite.

[0451] The second magnetic attraction assembly 28 includes a third magnet 2801 and a fourth magnet 2802 . The third magnet 2801 and the fourth magnet 2802 are disposed on the first beauty head 2 in a spaced-apart manner, and the polarities of the third magnet 2801 and the fourth magnet 2802 are opposite.

[0452] It should be noted that by providing magnets with opposite polarities, fool-proofing can be achieved, effectively preventing incorrect installation.

[0453] Since the first beauty head 2 in this embodiment utilizes microcurrent, it requires a power source. This power source is typically located within the beauty device body 1, where ample space is available. Of course, the first beauty head 2 can also draw power directly from an external source via a circuit board within the beauty device body 1. Therefore, an electrical connection is required between the first beauty head 2 and the beauty device body 1. The combination of the connecting terminal 5 and the contact terminal 6 establishes a pathway for electrical connection between the first beauty head 2 and the beauty device body 1. When the first beauty head 2 is mounted on the beauty device body 1, the connecting terminal 5 and the contact terminal 6 make contact and conduction, allowing the power source to supply power to the first beauty head 2. Since the second beauty head 3 does not require a power source, it does not require an electrical connection to the beauty device body 1.

[0454] In this embodiment, a connecting terminal 5 is provided on the first beauty head 2 , and a contact terminal 6 for cooperating with and electrically connecting to the connecting terminal 5 is provided on the beauty instrument body 1 .

[0455] There are many different designs for the arrangement positions of the connecting terminals 5 and the contact terminals 6. This embodiment only uses a few of them as examples for illustration.

[0456] For example, in the first embodiment, when the inner wall of the mounting position 4 is provided with a snap-fit ​​block 25 and the outer wall of the portion of the first beauty head 2 inserted into the mounting position 4 is provided with a snap-fit ​​groove 26, please refer to FIG4 and FIG7 . The snap-fit ​​groove 26 on the outer wall of the first beauty head 2 is provided with a connecting terminal 5, and the snap-fit ​​block 25 on the inner wall of the mounting position 4 is provided with a contact terminal 6 for cooperating with and electrically connecting to the connecting terminal 5.

[0457] In the second embodiment, when a snap-fit ​​groove 26 is provided on the inner wall of the mounting position 4 and a snap-fit ​​block 25 is provided on the outer wall of the portion of the first beauty head 2 inserted in the mounting position 4, a connecting terminal 5 is provided on the snap-fit ​​block 25 on the outer wall of the first beauty head 2, and a contact terminal 6 for cooperating with and electrically connecting to the connecting terminal 5 is provided in the snap-fit ​​groove 26 on the inner wall of the mounting position 4.

[0458] It should be noted that the design of the connection terminals 5 and contact terminals 6 is crucial to achieving a stable electrical connection. The connection terminals 5 are typically made of metal, which has sufficient conductivity and durability to ensure long-term reliability. The contact terminals 6 are designed to match the connection terminals 5 to ensure close contact and a stable electrical connection between the two, thereby ensuring the stability and reliability of the ion introduction process.

[0459] Optionally, the connecting terminal 5 is a ring-shaped structure surrounding the outer wall of the first beauty head 2;

[0460] And / or, the contact terminal 6 is an annular structure surrounding the inner wall of the mounting position 4 .

[0461] It should be noted that, with the above design, as long as at least one of the connecting terminal 5 and the contact terminal 6 is a ring-shaped structure, current can be effectively transferred to the first beauty head 2 even if misalignment occurs, thereby achieving efficient ion introduction and extraction. Furthermore, the ring-shaped design can improve current stability and reduce current loss and interference.

[0462] In addition, the connecting terminal 5 and the contact terminal 6 may also include a plurality of independent segments, which are connected by flexible materials to improve the flexibility and adaptability of the structure.

[0463] In the third embodiment, when the beauty instrument body 1 is provided with a first magnetic component 27 and the first beauty head 2 is provided with a second magnetic component 28, please refer to Figures 3 and 5. The first beauty head 2 is provided with a connecting terminal 5, and the beauty instrument body 1 is provided with a contact terminal 6 for cooperating with and electrically connecting to the connecting terminal 5.

[0464] In actual use, the user only needs to bring the first beauty head 2 close to the beauty instrument body 1. Through the action of magnetic attraction, the first beauty head 2 will automatically connect to the beauty instrument body 1. At the same time, the connecting terminal 5 and the contact terminal 6 will contact and conduct, achieving electrical connection. This quick and easy connection method brings a better user experience.

[0465] Please refer to FIG7 again. In this embodiment, the beauty instrument body 1 includes a first shell 101, a circuit board 102 and a first conductive electrode 103;

[0466] The circuit board 102 is arranged in the first housing 101, and the first conductive electrode 103 and the contact terminal 6 are arranged outside the first housing 101;

[0467] The first conductive electrode 103 and the contact terminal 6 are electrically connected to the circuit board 102 respectively.

[0468] It can be understood that the first conductive electrode 103 and the contact terminal 6 are arranged on the outside of the first shell 101. It should be understood that at least part of the structure of the first conductive electrode 103 and the contact terminal 6 is exposed to the outer surface of the first shell 101, so that the first conductive electrode 103 and the contact terminal 6 can be electrically connected to other conductive components.

[0469] It should be noted that when the first beauty head 2 is mounted on the beauty instrument body 1 , the first beauty head 2 is electrically connected to the contact terminal 6 via the connection terminal 5 , thereby being electrically connected to the circuit board 102 .

[0470] Optionally, a sensor for sensing the human body may be provided on the first beauty head 2. When the first beauty head 2 comes into contact with human skin, the sensor senses the human body, and the circuit board 102 controls the power supply to supply power to the first beauty head 2, thereby preventing the first beauty head 2 from performing ineffective work. That is, when the user forgets to turn off or accidentally turns on the beauty instrument, the first beauty head 2 is prevented from still outputting radio frequency current, thereby saving energy consumption and improving the intelligence of the beauty instrument.

[0471] The sensor may be, but is not limited to, an infrared sensor or a temperature sensor. The sensor detects the human epidermis. When no human epidermis is detected, the circuit board 102 controls the power supply to stop supplying power to the first beauty head 2. When human epidermis is detected, the circuit board 102 controls the power supply to supply power to the first beauty head 2.

[0472] 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 the various functions of the beauty instrument body 1. In view of the fact that these structural designs have been implemented in many related technologies and are not the focus of the design of this solution, they will not be elaborated in depth here.

[0473] Optionally, the first shell 101 is in a curved arc shape, so that the user can hold it easily without getting tired or slipping.

[0474] Please refer to FIG. 4 and FIG. 26 again. In this embodiment, the first beauty head 2 includes a second shell 201 and a second conductive electrode 202;

[0475] The second conductive electrode 202 is disposed in the second housing 201 and is electrically connected to the connecting terminal 5;

[0476] The first conductive electrode 103 and the second conductive electrode 202 are connected to each other through the human body.

[0477] It should be noted that, when in use, the first conductive electrode 103 contacts the human hand, and the second conductive electrode 202 contacts the human face, forming a circuit through the human body to achieve the lead-in or lead-out function of the second conductive electrode 202 .

[0478] Please refer to Figures 6 and 7 again, and in conjunction with Figure 9, in this embodiment, a driving mechanism 7 and an air supply mechanism 8 are further provided in the beauty instrument body 1, and the driving device 11 and the air supply mechanism 8 are electrically connected to the circuit board 102 respectively;

[0479] The second beauty head 3 includes a microneedle wafer 302 and an atomizing device;

[0480] The driving device 11 is used to drive the microneedle device 302 to reciprocate, and the gas supply mechanism 8 is connected to the atomizing device to supply gas to the atomizing device.

[0481] Specifically, the second beauty head 3 also includes a third shell 301, and the atomization device includes a gas flow channel 304, a liquid flow channel 305, a liquid outlet 306, an air inlet 307 and an air outlet 308. The end of the third shell 301 away from the first shell 101 is provided with a microneedle chip 302, and an atomization outlet 303 is opened; the gas flow channel 304 and the liquid flow channel 305 are provided in the third shell 301; the liquid outlet 306 of the liquid flow channel 305 is connected with the atomization outlet 303; the air inlet 307 and the air outlet 308 are respectively provided at both ends of the gas flow channel 304, the air inlet 307 is connected with the air supply mechanism 8, and the air outlet 308 surrounds part or all of the liquid outlet 306 of the liquid flow channel 305.

[0482] The gas provided by the gas supply mechanism 8 enters the gas flow channel 304 from the air inlet 307 and then flows out from the air outlet 308, causing a negative pressure to be formed at the liquid outlet 306 of the liquid flow channel 305. At this time, the essence in the liquid flow channel 305 can flow out from the liquid outlet 306 of the liquid flow channel 305 under the action of the negative pressure, and is sprayed into a small molecule mist to reach the human face.

[0483] It should be noted that because the second beauty head 3 utilizes microneedle wafers 302 to stimulate the skin, forming tiny skin channels on the skin's surface to allow nutrients or medications (collectively, essence) to penetrate the skin's interior and achieve a cosmetic effect, the microneedle wafers 302 must reciprocate in contact with the skin to promote the absorption of the essence. This necessitates the provision of a drive mechanism 7. Specifically, the drive mechanism 7 reciprocates by driving the second beauty head 3, thereby reciprocating the microneedle wafers 302. This stimulates the skin with the microneedle device 302, further allowing the atomized essence molecules to penetrate the skin.

[0484] 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, stimulating collagen proliferation and cell regeneration, and repairing 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.

These terms are used only to more conveniently describe and explain the essence of this application; interpreting them as any additional limitations is contrary to the spirit of this application.

[0486] The present application provides a multi-purpose beauty instrument, in which the main body of the beauty instrument can be detachably installed with two beauty heads, namely an ion introduction head and a water light needle head; since the beauty head has two beauty heads with different functions, the beauty instrument has multiple uses, realizing the versatility of the beauty instrument, so that users can flexibly choose to use different beauty heads according to their own skin care needs, which is both convenient and practical; at the same time, this design reduces the user's usage cost, facilitates management and carrying, significantly improves the user's usage experience, has high economic value and practicality, and can meet the needs of a large number of users.
