[0045] This application provides a beauty atomizing device 1.

[0046] Please see Figures 1 to 6 The beauty atomizing device 1 includes an ultrasonic head 10, a main unit 20, and a sealing element 40.

[0047] The ultrasonic head 10 includes an ultrasonic transducer 11 and a vibrating element 12 connected to each other. The ultrasonic transducer 11 is used to generate acoustic vibrations, and the vibrating element 12 has a vibrating end face 12a at the end away from the ultrasonic transducer 11.

[0048] The host 20 includes a housing assembly 21 and a power supply assembly 22 disposed within the housing assembly 21.

[0049] The ultrasonic head 10 is an independent, replaceable module that is detachably connected to the housing assembly 21 along a first direction. The ultrasonic head 10 is also detachably connected to the power supply assembly 22.

[0050] The seal 40 is disposed between the ultrasonic head 10 and the housing assembly 21.

[0051] The ultrasonic transducer 11 can receive electrical signals from the power supply component 22 and convert them into high-frequency mechanical vibrations, i.e., acoustic vibrations. The vibrating element 12 is used to receive the acoustic vibrations from the ultrasonic transducer 11 and act on the atomized liquid or skin through the vibrating end face 12a.

[0052] The beauty atomizing device 1 can contact the skin or atomized liquid through the vibrating end face 12a to perform skincare for the user. Here, the atomized liquid can be a beauty serum, toner, lotion, essence, hydrogel, whitening lotion, or other beauty serums, or it can be a medicinal liquid. The atomized liquid is atomized by ultrasonic vibration, which promotes the penetration of the atomized liquid into the skin, increases the skin's absorption of the atomized liquid, and enhances the skincare effect.

[0053] Understandably, the beauty atomizing device 1 can be applied to various skincare scenarios. For example, it can come into contact with the skin through the vibrating end face 12a to help remove dirt and oil deep in the pores; or, it can atomize beauty serum through the vibrating end face 12a to increase the absorption of skincare products and allow active ingredients to penetrate deeper into the skin; of course, it can also come into contact with the skin through the vibrating end face 12a to promote blood circulation and accelerate the self-repair of sensitive skin.

[0054] The material of the ultrasonic transducer 11 is not limited. Exemplarily, the ultrasonic transducer 11 includes a piezoelectric element, such as piezoelectric ceramic, which generates high-frequency mechanical vibration. The vibrating element 12 amplifies the particle displacement or velocity of the mechanical vibration of the ultrasonic transducer 11 and concentrates the ultrasonic energy on the vibrating end face 12a, thereby allowing it to contact the skin or atomized liquid through the vibrating end face 12a.

[0055] The shape of the vibrating end face 12a is not limited. For example, the shape of the vibrating end face 12a may include one of the following: rectangle, ellipse, or oval. An oval is a closed figure formed by dividing a circle through its center into two semicircular arcs that are translated in opposite directions and connecting the endpoints of the two semicircular arcs with two parallel lines of equal length.

[0056] The housing assembly 21 serves as the exterior component of the beauty atomizing device 1, providing protection for components such as the power supply assembly 22 housed therein, thereby reducing the likelihood of impact damage to the power supply assembly 22 and other components.

[0057] The ultrasonic head 10 is an independent, replaceable module that is detachably connected to the housing assembly 21 along the first direction. This means that the ultrasonic head 10 is detachably connected to the main unit 20 through the detachable connection with the housing assembly 21. The ultrasonic head 10 can be connected to the housing assembly 21 as a whole, or it can be detached from the housing assembly 21. When it is necessary to use ultrasonic heads 10 with different powers or to maintain the ultrasonic head 10, the connection between the ultrasonic head 10 and the housing assembly 21 can be disconnected to achieve different usage effects or increase the working reliability of the ultrasonic head 10.

[0058] The ultrasonic head 10 and the power supply assembly 22 are detachably connected, that is, the electrical connection between the ultrasonic head 10 and the power supply assembly 22 is detachable, which facilitates the detachable connection between the ultrasonic head 10 and the housing assembly 21 without damaging the power supply assembly 22.

[0059] It is understood that the first direction is any direction. The first direction refers to the docking direction between the ultrasonic head 10 and the housing assembly 21, and does not limit the docking method between the ultrasonic head 10 and the housing assembly 21. For example, the first direction can be the axial direction of the housing assembly 21, which is the same as the axial direction of the beauty atomizing device 1.

[0060] The seal 40 is disposed between the ultrasonic head 10 and the housing assembly 21. For example, the deformation of the seal 40 makes it difficult for leakage at the joint between the ultrasonic head 10 and the housing assembly 21, thereby improving the sealing performance at the joint and reducing the probability of liquid entering the beauty atomizing device 1 from the joint and causing damage to the internal components when the beauty atomizing device 1 is working or being cleaned and disinfected. This increases the structural reliability of the beauty atomizing device 1.

[0061] The material of the seal 40 is not limited; for example, the seal 40 can be a waterproof component such as silicone or rubber.

[0062] It should be noted that both the ultrasonic head and the housing assembly are made of rigid materials, which makes it easy for liquid to enter at the interface. This can lead to liquid entering the beauty atomizing device during use, cleaning, or disinfection, affecting its normal operation or causing damage to internal components.

[0063] The beauty atomizing device 1 provided in this application embodiment has an ultrasonic head 10 that is detachably connected to the main unit 20. Different power ultrasonic heads 10 can be replaced as needed, allowing one main unit 20 to be compatible with multiple ultrasonic heads 10 to achieve different effects. This also facilitates maintenance of the ultrasonic heads 10, increasing the reliability and flexibility of the beauty atomizing device 1. Secondly, by providing a seal 40 at the connection between the housing assembly 21 and the ultrasonic head 10, leakage is prevented. The connection between the housing assembly 21 and the ultrasonic head 10 is relatively simple, and liquid is less likely to enter the beauty atomizing device 1 from the connection point and damage internal components. This results in good operational stability for the beauty atomizing device 1, improving the user experience. The ultrasonic transducer 11 can drive the vibrating element 12 with relatively low energy, requiring no large driving energy and ensuring high operational reliability.

[0064] The detachable docking method between the housing assembly 21 and the ultrasonic head 10 is not limited, and can be snap-fit, riveted, threaded, magnetically attached, etc., without any restrictions.

[0065] In some embodiments, the housing assembly 21 is snap-fitted to the ultrasonic head 10.

[0066] For example, one of the housing assembly 21 and the ultrasonic head 10 is formed with a slot, and the other is formed with a buckle. The ultrasonic head 10 and the housing assembly 21 are detachably connected through the cooperation of the slot and the buckle.

[0067] In this embodiment, the ultrasonic head 10 and the housing assembly 21 are detachably connected through the cooperation of the slot and the buckle. The slot and the buckle have a simple structure, which facilitates assembly and increases assembly efficiency. When it is necessary to disconnect the connection between the housing assembly 21 and the ultrasonic head 10, it is only necessary to disconnect the slot and the buckle, which is convenient to operate.

[0068] It is understandable that the housing assembly 21 may have a slot and the ultrasonic head 10 may have a buckle, or the ultrasonic head 10 may have a slot and the housing assembly 21 may have a buckle; there is no limitation on this.

[0069] In other embodiments, the housing assembly 21 is threadedly connected to the ultrasonic head 10.

[0070] For example, one of the housing assembly 21 and the ultrasonic head 10 has an internal thread and the other has an external thread, and the ultrasonic head 10 and the housing assembly 21 are detachably connected by the engagement of the internal and external threads.

[0071] In this embodiment, the ultrasonic head 10 and the housing assembly 21 are detachably connected by the cooperation of the internal and external threads.

[0072] For example, by applying an external force to either the housing assembly 21 or the ultrasonic head 10, causing it to rotate, the internal and external threads engage, thereby achieving a stable connection and positioning between the housing assembly 21 and the ultrasonic head 10. When it is necessary to disengage the connection between the housing assembly 21 and the ultrasonic head 10, an external force is applied to either the housing assembly 21 or the ultrasonic head 10 again, causing it to rotate in the opposite direction, disengaging the internal and external threads, thereby achieving disassembly between the housing assembly 21 and the ultrasonic head 10. Thus, the assembly and disassembly of the housing assembly 21 and the ultrasonic head 10 are simple, quick, and highly convenient. Furthermore, the engagement of the internal and external threads conceals the connection internally, without affecting the appearance of the beauty atomizing device 1.

[0073] It is understandable that the form of internal and external threads is not limited; they can be coarse threads, fine threads, trapezoidal threads, or sawtooth threads, etc., and there are no restrictions here.

[0074] In this embodiment, the housing assembly 21 and the ultrasonic head 10 are detachably connected via internal and external threads, meaning that a reliable installation connection can be achieved without the use of screws. Furthermore, when disassembly is required, only the engagement of the internal and external threads needs to be released, resulting in high assembly and disassembly efficiency. Simultaneously, the form of the internal and external threads facilitates the compression deformation of the seal 40 during connection, increasing the sealing reliability at the mating point between the housing assembly 21 and the ultrasonic head 10.

[0075] It is understandable that when the housing assembly 21 is provided with internal threads, the ultrasonic head 10 is provided with external threads; when the housing assembly 21 is provided with external threads, the ultrasonic head 10 is provided with internal threads.

[0076] The ultrasonic head 10 is not limited to any part that can be detachably connected to the housing assembly 21; it can be an ultrasonic transducer 11 or a vibrating element 12.

[0077] For example, in some embodiments, please refer to Figure 2 , Figure 5 and Figure 6 The side of the vibrating element 12 away from the vibrating end face 12a is open to form an open space 12b.

[0078] The ultrasonic transducer 11 is disposed within the open space 12b, and a portion of the housing assembly 21 extends into the open space 12b.

[0079] The inner wall of the open space 12b is provided with an internal thread 12c, and the part of the housing assembly 21 located in the open space 12b has an external thread 211a. The housing assembly 21 or the vibrating element 12 can rotate relative to each other under the action of external force to realize the threaded connection between the internal thread 12c and the external thread 211a, and realize the electrical connection between the power supply assembly 22 and the ultrasonic head 10.

[0080] In this embodiment, the ultrasonic head 10 is detachably connected to the housing assembly 21 via the vibrating element 12.

[0081] The ultrasonic transducer 11 is disposed in the open space 12b, which facilitates connection with the vibrating element 12. The open space 12b can protect the ultrasonic transducer 11, reduce the probability of damage to the ultrasonic transducer 11, facilitate the normal operation of the ultrasonic transducer 11, and facilitate the rapid transmission of vibration to the vibrating end face 12a.

[0082] Please refer to the following when docking: Figure 5 The portion of the housing assembly 21 with the external thread 211a is inserted into the open space 12b to engage with the internal thread 12c of the open space 12b. By rotating the housing assembly 21 or the ultrasonic head 10, a tight fit between the ultrasonic head 10 and the housing assembly 21 is achieved. After the housing assembly 21 and the ultrasonic head 10 are engaged, the power supply assembly 22 can also be electrically connected to the ultrasonic head 10 so that the power supply assembly 22 can provide power to the ultrasonic head 10.

[0083] In this embodiment, by providing an internal thread 12c in the open space 12b and an external thread 211a in the housing assembly 21, the ultrasonic head 10 is connected to the housing assembly 21. The internal thread 12c can be hidden inside the vibrating element 12, making it easier to expose the outer surface of the vibrating element 12 to the outside of the beauty atomizing device 1, thus increasing operational reliability. At the same time, it also makes it easier to hide the electrical connection between the ultrasonic head 10 and the power supply assembly 22 inside, thus increasing safety during use.

[0084] The installation method of seal 40 is not limited.

[0085] In some embodiments, please refer to Figure 2 and Figure 5 The ultrasonic head 10 has a first end face 12d on the side away from the vibration end face 12a, and the housing assembly 21 has a second end face 211b. The first end face 12d and the second end face 211b are arranged face to face. The first end face 12d is recessed in the axial direction toward the vibration end face 12a to form a groove 12e. The sealing member 40 is disposed in the groove 12e and sandwiched between the first end face 12d and the second end face 211b.

[0086] For example, the first end face 12d may be formed on the vibrating member 12.

[0087] In this embodiment, the groove 12e allows for the installation and positioning of the seal 40, ensuring accurate and reliable positioning and increasing its sealing reliability. During assembly, the seal 40 can be placed in the groove 12e first, and then the ultrasonic head 10 and the seal 40 can be docked with the housing assembly 21. This prevents displacement of the seal 40 during docking of the housing assembly 21 and the ultrasonic head 10, resulting in high sealing reliability.

[0088] The seal 40 can be a sealing ring, such as a waterproof ring, and the groove 12e can be formed as an annular groove 12e.

[0089] The power supply component 22 provides power to the ultrasonic head 10 in any way.

[0090] In some embodiments, please refer to Figure 4 and Figure 6 The vibrating element 12 is a metal part. The main unit 20 includes a first conductive spring needle 23 and a second conductive spring needle 25. The first conductive spring needle 23 and the second conductive spring needle 25 are spaced apart in the housing assembly 21 along the second direction. One end of the first conductive spring needle 23 is electrically connected to the power supply assembly 22, and the other end of the first conductive spring needle 23 is connected to the ultrasonic transducer 11. One end of the second conductive spring needle 25 is electrically connected to the power supply assembly 22, and the other end of the second conductive spring needle 25 is connected to the vibrating element 12 to form a closed loop. The first direction is perpendicular to the second direction.

[0091] The vibrating element 12 is a metal part, meaning that the vibrating element 12 has electrical conductivity. For example, the vibrating element 12 can be made of materials such as copper and copper alloys, iron and iron alloys, aluminum and aluminum alloys.

[0092] One end of the first conductive spring pin 23 is electrically connected to the power supply component 22, and the other end is connected to the ultrasonic transducer 11, thus forming the first electrode. One end of the second conductive spring pin 25 is electrically connected to the power supply component 22, and the other end is connected to the vibrating element 12, thus forming the second electrode. The first and second electrodes together provide electrical energy to the ultrasonic transducer 11, and the polarity of the first and second electrodes is not limited. For example, in some embodiments, the first electrode is the positive electrode and the second electrode is the negative electrode, so as to transmit power to the ultrasonic transducer 11. Thus, electrical connection can be achieved without welding electrodes to the ultrasonic transducer 11. The first conductive spring pin 23 can abut against the ultrasonic transducer 11 to achieve power transmission, reducing damage to the ultrasonic transducer 11 and reducing the difficulty of disassembly and assembly, making it easier to achieve a separable electrical connection between the ultrasonic head 10 and the power supply component 22.

[0093] The first conductive spring pin 23 and the second conductive spring pin 25 can serve as a bridge connecting the ultrasonic head 10 and the power supply assembly 22, increasing the reliability of the electrical connection, eliminating the need for wiring, and reducing assembly difficulty. The first conductive spring pin 23 and the second conductive spring pin 25 have a certain degree of elasticity, which facilitates stable docking with the ultrasonic transducer 11 and the vibrating component 12, respectively.

[0094] The first conductive spring pin 23 and the second conductive spring pin 25 are arranged at intervals, that is, the first electrode and the second electrode do not interfere with each other and are arranged at intervals, which can increase the reliability of power supply.

[0095] The second direction is perpendicular to the first direction, which makes it easier to make full use of space and reduce the size of the beauty atomizing device 1 along the first direction.

[0096] It is understandable that the surface of the ultrasonic transducer 11 that comes into contact with the first conductive spring needle 23 may be coated with a conductive coating to improve the reliability of the electrical connection between the ultrasonic transducer 11 and the first conductive spring needle 23.

[0097] It is understandable that the first conductive spring pin 23 and the second conductive spring pin 25 can be directly electrically connected to the power supply component 22, or they can be electrically connected to the power supply component 22 through an intermediate conductive structure.

[0098] In some embodiments, please refer to Figure 4 and Figure 6 The host 20 includes a first conductive elastic component 24. One end of the first conductive elastic component 24 is electrically connected to the end of the first conductive spring needle 23 away from the ultrasonic transducer 11, and the other end of the first conductive elastic component 24 is electrically connected to the power supply component 22. The first conductive spring needle 23 can maintain an electrical connection with the ultrasonic transducer 11 under the action of the elastic force of the first conductive elastic component 24.

[0099] In this embodiment, the first conductive elastic component 24 enables the first conductive spring pin 23 to be electrically connected to the power supply component 22, thereby achieving the electrical connection between the ultrasonic transducer 11 and the power supply component 22. At the same time, it can also compensate for assembly tolerances by relying on its own elastic deformation capability, so that the first conductive spring pin 23 can maintain a reliable electrical connection with the ultrasonic transducer 11. In addition, it can also provide positioning support for the ultrasonic transducer 11, with minimal impact on the load of the ultrasonic transducer 11.

[0100] For example, the end of the first conductive spring needle 23 away from the first conductive elastic component 24 abuts against the ultrasonic transducer 11.

[0101] In some embodiments, please refer to Figure 4 and Figure 6The main unit 20 includes a second conductive elastic component 26. One end of the second conductive elastic component 26 is electrically connected to the end of the second conductive spring needle 25 away from the vibrating element 12, and the other end of the second conductive elastic component 26 is electrically connected to the power supply component 22. The second conductive spring needle 25 can maintain an electrical connection with the vibrating element 12 under the action of the elastic force of the second conductive elastic component 26.

[0102] In this embodiment, the second conductive elastic component 26 not only enables the second conductive spring pin 25 to be electrically connected to the power supply component 22, thereby forming a stable closed circuit, but also compensates for the assembly defects by its own elastic deformation capability, so that the second conductive spring pin 25 can maintain a reliable electrical connection with the vibrating component 12. At the same time, it can also provide positioning support for the vibrating component 12 and have little impact on the load of the vibrating component 12.

[0103] The end of the second conductive spring pin 25 away from the second conductive elastic component 26 can directly contact the vibrating element 12, or it can be connected to the vibrating element 12 through an intermediate structure.

[0104] For example, in some embodiments, please refer to Figure 4 and Figure 6 The main unit 20 includes a connecting post 27, which passes through the housing assembly 21 and is located between the second conductive spring pin 25 and the vibrating element 12. That is, the second conductive spring pin 25 is stably electrically connected to the vibrating element 12 through the connecting post 27. The outer diameter of the connecting post 27 can be larger than the outer diameter of the second conductive spring pin 25. This allows the second conductive spring pin 25 to be connected to the vibrating element 12 in a limited space, reducing assembly limitations caused by the structure of the second conductive spring pin 25 and the vibrating element 12, and compensating for assembly tolerances. At the same time, the connecting post 27 can also easily isolate the first conductive spring pin 23 and the second conductive spring pin 25, increasing assembly reliability.

[0105] For example, please refer to Figure 4 and Figure 6 The main unit 20 may be equipped with a support frame 28, which is connected to the housing assembly 21 to support and position the first conductive spring pin 23 and the second conductive spring pin 25.

[0106] The specific structure of the first conductive elastic component 24 and the second conductive elastic component 26 is not limited. They can be conductive springs or conductive sheets, etc. For example, the first conductive elastic component 24 and the second conductive elastic component 26 are conductive springs. One end of the first conductive elastic component 24 is sleeved on the end of the first conductive spring needle 23 away from the ultrasonic transducer 11, and one end of the second conductive elastic component 26 is sleeved on the end of the second conductive spring needle 25 away from the ultrasonic transducer 11.

[0107] In some embodiments, please refer to Figure 2 , Figure 4 , Figure 5 and Figure 6 The host 20 includes a temperature detection module 29. One end of the temperature detection module 29 is disposed in the first conductive spring needle 23, and the other end of the temperature detection module 29 is electrically connected to the power supply component 22. The temperature detection module 29 is used to detect the temperature of the ultrasonic transducer 11 and transmit the detected temperature signal to the power supply component 22.

[0108] It is understandable that ultrasonic transducers inevitably generate heat when converting electrical energy into mechanical vibration. If the temperature is too high, it can easily damage the ultrasonic transducer itself and surrounding components, affecting its service life and efficiency.

[0109] In this embodiment, the temperature of the ultrasonic transducer 11 is detected by the temperature detection module 29. This means that by monitoring the temperature, the operating temperature of the ultrasonic transducer 11 can be controlled within a safe range, reducing the chance of the ultrasonic transducer 11 overheating and being damaged, and increasing the working reliability of the beauty atomizing device 1.

[0110] One end of the temperature detection module 29 is disposed inside the first conductive spring needle 23. The temperature detection module 29 can be disposed at the end of the first conductive spring needle 23 near the ultrasonic transducer 11 to increase the accuracy of temperature detection. The temperature signal detected by the temperature detection module 29 can be transmitted to the power supply component 22. The power supply component 22 processes and analyzes the temperature signal. If the temperature rises, it can reduce the power output to cool down, or activate the cooling mechanism of the beauty atomizing device 1, without limitation.

[0111] The specific form of the temperature detection module 29 is not limited. For example, the temperature detection module 29 can be an NTC (Negative Temperature Coefficient Thermistor) temperature sensor. NTC temperature sensors are sensitive to temperature changes and can exhibit a large resistance change within a very small range, thereby responding quickly to temperature changes.

[0112] The specific structure of the housing assembly 21 is not limited.

[0113] In some embodiments, please refer to Figures 1 to 4 , Figure 6 The housing assembly 21 includes a first housing portion 211, a bracket 212, and a second housing portion 213. The first housing portion 211 is detachably connected to the ultrasonic head 10. The second housing portion 213 is disposed on the side of the first housing portion 211 away from the vibrating end face 12a. The bracket 212 connects the first housing portion 211 and the second housing portion 213. One end of the power supply assembly 22 is fixed to the bracket 212, and the other end is disposed inside the second housing portion 213.

[0114] In this embodiment, the housing assembly 21 is detachably connected to the ultrasonic head 10 via the first housing portion 211, and the power supply assembly 22 is fixed and housed through the cooperation of the bracket 212 and the second housing portion 213. This provides sufficient installation space for the power supply assembly 22, reduces the probability of displacement, and increases installation reliability. The arrangement of the first housing portion 211, the second housing portion 213, and the bracket 212 facilitates the assembly of various parts of the main unit 20. At the same time, the bracket 212 also enhances the overall strength of the housing assembly 21.

[0115] The first conductive spring pin 23 and the second conductive spring pin 25 can be inserted into the first housing to achieve electrical connection with the ultrasonic transducer 11 and the vibrating element 12. The support frame 28 of the first conductive spring pin 23 and the second conductive spring pin 25 can be connected to the bracket 212.

[0116] For example, please refer to Figure 2 , Figure 4 and Figure 6 The host 20 includes at least one connector 30. One end of the connector 30 is connected to the power supply assembly 22, and the other end passes through the bracket 212 and is fixedly connected to the first housing 211. In this way, the power supply assembly 22, the bracket 212 and the first housing 211 can be fixed together by the connector 30, so that one end of the power supply assembly 22 is fixed on the bracket 212.

[0117] In some embodiments, please refer to Figure 2 , Figure 4 and Figure 6 At least a portion of the bracket 212 is a light guide structure, and at least a portion of the light guide structure is exposed on the outer surface of the beauty atomizing device 1. The power supply component 22 includes a main board 221 and a lamp board 222. The main board 221 is electrically connected to the lamp board 222, and the lamp board 222 is connected to the bracket 212.

[0118] Here, the light panel 222 can generate light under the power of the main board 221, and the light can be exposed on the outer surface of the beauty atomizing device 1 through the bracket 212.

[0119] The mainboard 221 is the control center of the power supply component 22, which can provide power to the lamp board 222, ultrasonic head 10, etc., and control the output power.

[0120] The lamp board 222 integrates multiple electronic components and circuits, and can realize the lighting function through electronic signals and power supply. For example, the lamp board 222 may include an LED lamp board 222, a light guide plate, and a diffuser plate, etc.

[0121] The electrical connection method between the lamp board 222 and the main board 221 is not limited. For example, please refer to [link to example]. Figure 6The motherboard 221 can be equipped with a header pin 2211, and the lamp board 222 can be equipped with a header pin 2221. The electrical connection between the motherboard 221 and the lamp board 222 is achieved by plugging in the header pin 2211 and the header pin 2221.

[0122] Of course, in some embodiments, please refer to Figure 2 , Figure 4 and Figure 6 The power supply assembly 22 may also be equipped with a connecting bracket 223. The lamp board 222 can be connected to the bracket 212 through the connecting bracket 223 to reduce damage to the lamp board 222. The main board 221 can be fastened to the connecting bracket 223 by fasteners 31, thereby fixing the main board 221 and the lamp board 222. The connecting bracket 223 can be a PCBA (Printed Circuit Board Assembly) bracket.

[0123] In this embodiment, at least a portion of the bracket 212 is a light guide structure, which means that when the lamp plate 222 is working, the light can be exposed on the outer surface of the beauty atomizing device 1 through the light guide structure so that the user can know that the beauty atomizing device 1 is working, thereby indicating that the beauty atomizing device 1 is working and increasing the reliability of the operation.

[0124] The specific structure of the bracket 212 is not limited.

[0125] In some embodiments, please refer to Figure 2 , Figure 4 and Figure 6 The bracket 212 includes a first connecting part 2121 and a second connecting part 2122 that are connected to each other. A portion of the outer peripheral surface of the first connecting part 2121 forms the outer surface of the beauty atomizing device 1. One end of the first connecting part 2121 along a first direction is connected to the first shell part 211, and the other end is connected to the second shell part 213. A portion of the second connecting part 2122 is sandwiched between the first connecting part 2121 and the first shell part 211, and another portion is sandwiched between the first connecting part 2121 and the second shell part 213 to achieve a sealed fit between the first connecting part 2121 and the first shell part 211 and the second shell part 213.

[0126] In other words, part of the outer peripheral surface of the first connecting part 2121 can be seen from the outer surface of the beauty atomizing device 1 so that the lamp plate 222 can emit light through the bracket 212. The second connecting part 2122 is hidden in the internal space of the main unit 20 and is not an external part.

[0127] In this embodiment, the first connecting part 2121 is connected to the first shell part 211 and the second shell part 213 respectively, and the second connecting part 2122 is sandwiched at the connection between the first connecting part 2121 and the first shell part 211, and at the connection between the first connecting part 2121 and the second shell part 213. This can increase the sealing performance of the mating point and reduce the risk of liquid entering the interior. The first connecting part 2121 can be a structure with high hardness to increase the overall structural strength, and the second connecting part 2122 can be a structure with low hardness to achieve sealing through deformation.

[0128] The connection method between the first connecting part 2121 and the first housing part 211 and the second housing part 213 is not limited. For example, it can be a snap-fit ​​connection.

[0129] In some embodiments, the first connecting part 2121 is a rigid light guide structure, and the second connecting part 2122 is a flexible light guide structure.

[0130] In this embodiment, the first connecting part 2121 has sufficient hardness and is not easily deformed, which facilitates the increase of structural strength, provides sufficient installation and connection support, and has strong impact resistance; the second connecting part 2122 can undergo a certain degree of deformation, and when it docks with the first shell part 211 and the second shell part 213, it can increase the sealing performance at the docking point with the first shell part 211 and the second shell part 213 through its own deformation, thereby improving the overall sealing performance.

[0131] Both the first connecting part 2121 and the second connecting part 2122 are light guiding structures, which can facilitate the export of light generated by the lamp board 222.

[0132] The molding method of the first connecting part 2121 and the second connecting part 2122 is not limited.

[0133] In some embodiments, the first connecting portion 2121 and the second connecting portion 2122 are formed by two-color injection molding.

[0134] Two-color injection molding refers to injecting two different materials into the same mold to create structures with different colors or functions in a single molding process.

[0135] In this embodiment, the first connecting part 2121 and the second connecting part 2122 can be made of different materials and formed by injection molding in one step.

[0136] The first connecting part 2121 is made of a material with high hardness, such as stainless steel, aluminum alloy or plastic parts with high hardness.

[0137] The second connecting part 2122 is made of a material with low hardness, such as silicone rubber or polyurethane foam.

[0138] In this embodiment, two-color injection molding is used to mold the first connecting part 2121 and the second connecting part 2122, which are made of different materials, together. This meets manufacturing requirements while avoiding multiple injection molding processes, saving time and costs. It also reduces molding defects in the first connecting part 2121 and the second connecting part 2122, resulting in good sealing at the joint and high assembly reliability. Furthermore, the reliability and dimensions of the connection can be guaranteed through the injection mold, saving assembly time.

[0139] In some embodiments, please refer to Figure 2 , Figure 4 and Figure 6 The main unit 20 also includes a connecting tube 32, which contains a cable 33. The end of the housing assembly 21 away from the vibration end face 12a has an opening 21a. A portion of the connecting tube 32 enters the housing assembly 21 through the opening 21a and is connected to the power supply assembly 22, and the opening 21a is closed. The other portion of the connecting tube 32 is exposed on the outer surface of the beauty atomizing device 1 for connection to external devices.

[0140] It is understandable that control commands can be issued through external devices to adjust the output power of the power supply component 22 or the working mode of the beauty atomizing device 1.

[0141] In this embodiment, the connecting tube 32 can integrate the cable 33 together and realize the connection between the cable 33 and the power supply component 22 and external devices, so as to increase the reliability of electrical connection and facilitate the operation of the beauty atomizing device 1.

[0142] In some embodiments, please refer to Figure 2 , Figure 4 and Figure 6 The main unit 20 includes an end cap 34 and a potting layer. The end cap 34 is sleeved on the outer periphery of the mating point between the connecting tube 32 and the housing assembly 21.

[0143] In this embodiment, the end cap 34 can guide and position the connection tube 32 to the housing assembly 21, reduce installation deviation, and increase assembly reliability.

[0144] The potting layer is used to fix the end cap 34, the connecting tube 32, and the housing assembly 21.

[0145] In some embodiments, the potting layer is constructed by potting adhesive from the inner surface of the housing assembly 21 toward the junction of the end cap 34 and the connecting tube 32 and the junction of the connecting tube 32 and the housing assembly 21.

[0146] By injecting adhesive from the inner surface of the housing assembly 21 to the joint between the end cap 34 and the connecting tube 32, and the joint between the connecting tube 32 and the housing assembly 21, an adhesive layer is formed. This can fix the connecting tube 32 to the housing assembly 21 and the end cap 34, and reduce the probability of liquid entering from the joint between the end cap 34 and the connecting tube 32, and the joint between the connecting tube 32 and the housing assembly 21. The beauty atomizing device 1 has good sealing and waterproof performance, and the electrical connection between the cable 33 and the power supply assembly 22 and external equipment can be stable and reliable.
