Description

Technical Field

[0001] This utility model relates to the field of beauty equipment technology, and in particular to a beauty instrument. Background Technology

[0002] Nowadays, beauty devices are the core products in the home beauty field. With their ability to regulate and improve the condition of the body and facial skin according to the body's physiological functions, they have become a popular choice for consumers' daily beauty care. Moreover, their beauty functions are constantly expanding, covering multiple dimensions such as whitening, skin rejuvenation, spot removal, wrinkle removal, and hair removal. At the same time, based on different technical principles such as ultrasonic induction, photon skin rejuvenation, and RF radiofrequency skin tightening, a wide variety of product types have been derived.

[0003] To enhance ease of use and maintenance flexibility, beauty devices often employ a detachable and modular structure for the main body and auxiliary heads. This allows for convenient maintenance and extends the device's lifespan by disassembling or replacing the auxiliary heads. In related technical solutions, the auxiliary head and main body of the beauty device typically house the beauty component and heat conduction component, respectively. After the auxiliary head and main body are assembled, the beauty component and heat conduction component must fit together snugly to achieve the corresponding beauty function. Specifically, the heat conduction component can absorb heat from the beauty component to create a cooling effect on the skin; alternatively, it can transfer heat to the beauty component to create a warming effect on the skin.

[0004] However, in existing technologies, the fit between the beauty components and the heat conduction components is often not tight enough. This defect directly leads to a reduction in the heat conduction efficiency between the two, which in turn seriously affects the actual effect of the beauty device's cold or hot compress function. Utility Model Content

[0005] The main purpose of this utility model is to propose a beauty device that aims to solve the technical problems of current beauty devices that use a detachable combination structure of the body and the auxiliary head, resulting in poor adhesion between the beauty components and the heat conduction components, low heat conduction efficiency, and affecting the beauty effect.

The fuselage is provided with a heat conduction component, which is exposed on the inner wall of the mounting cavity.

[0008] The accessory head is provided with a beauty component. The accessory head is adapted to the mounting cavity and is detachably disposed in the mounting cavity through the cavity opening. The accessory head has a first end and a second end opposite to each other. The first end is inserted into the mounting cavity, and the second end is exposed at the cavity opening.

[0022] A heat-conducting element is movably disposed on the side of the cooling chip facing the second opening, and the heat-conducting element protrudes from the inner wall of the mounting cavity through the mounting port. The light-transmitting element presses the heat-conducting element to make the heat-conducting element abut against the first thermally conductive silicone sheet.

[0023] Optionally, the heat-conducting component includes a heat-conducting cover, the heat-conducting cover including a main body and a protruding edge extending from the edge of the main body;

[0029] In this utility model beauty device, the auxiliary head is adapted to the mounting cavity on the device body and is detachably installed in the mounting cavity through the cavity opening. The first end of the auxiliary head is inserted into the mounting cavity, and the second end is exposed at the cavity opening. The cross-sectional area of ​​the mounting cavity gradually decreases along the direction from the cavity opening toward its bottom wall, so that the outer wall of the auxiliary head and the inner wall of the mounting cavity are wedge-shaped and tightly squeezed together. This causes the light-transmitting component on the auxiliary head to fit tightly with the heat conduction component exposed on the inner wall of the mounting cavity, thereby improving heat conduction efficiency and ensuring the beauty effect.

[0038] The solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0039] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0040] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0041] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0042] like Figure 1 As shown, in related technologies, the connection scheme between the auxiliary head and the body mostly adopts a snap-fit ​​structure, specifically a matching structure design of a slot and a hook 332. Although it achieves a detachable function, in actual use, the user needs to precisely align the hook 332 with the slot and apply force to engage it during assembly, and find a specific unlocking position and apply appropriate force during disassembly. The disassembly and assembly process is cumbersome and time-consuming, and it is also easy for the hook to break or deform due to improper operation, affecting the connection stability and normal use of the equipment.

[0043] Reference Figure 2 This utility model embodiment proposes a beauty device 100, which has a conveniently detachable accessory head 120. Through an innovative design of the connection structure between the main body 110 and the accessory head 120, the drawbacks of traditional snap-fit ​​connections are solved, enabling quick assembly and disassembly and stable fixation of the accessory head 120. It can be widely used in home beauty care scenarios. Specifically, the beauty device 100 can be a hair removal device, including but not limited to this.

[0044] Reference Figure 3 and Figure 4 The beauty device 100 includes:

[0045] The fuselage 110 has a mounting cavity 111 and a cavity opening 112 communicating with the mounting cavity 111. The cavity opening 112 is located at one end of the fuselage 110 and is disposed opposite to the bottom wall of the mounting cavity 111. The cross-sectional area of ​​the mounting cavity 111 gradually decreases along the direction of the cavity opening 112 toward its bottom wall.

[0046] The accessory head 120 is provided with a beauty component 121. The accessory head 120 is adapted to the mounting cavity 111 and is detachably disposed in the mounting cavity 111 through the cavity opening 112. The accessory head 120 has a first end and a second end opposite to each other. The first end is inserted into the mounting cavity 111 and the second end is exposed at the cavity opening 112.

[0047] like Figure 3 and Figure 4 As shown, the beauty device 100 in this embodiment includes two core components: a body 110 and an accessory head 120. The two are detachably connected through a matching structural design. The body 110 serves as the main support and functional control carrier of the beauty device 100, and is shaped like a handle for the user to hold. The body 110 has an internal mounting cavity 111 for mounting the accessory head 120, and one end of the body 110 has an opening 112 communicating with the mounting cavity 111. The opening 112 is positioned opposite to the bottom wall of the mounting cavity 111, meaning that the mounting cavity 111 is a cavity structure with one open end and one closed end, with the open end being the opening 112 and the closed end being the bottom wall.

[0048] The structural feature of the mounting cavity 111 is that, along the direction from the cavity opening 112 towards the bottom wall, the cross-sectional area of ​​the mounting cavity 111 continuously and uniformly decreases, forming a gradually narrowing cavity structure with a wide entrance and a narrow bottom. The core purpose of this structural design is to form a wedge-shaped fit with the auxiliary head 120, providing a structural basis for plug-in connection. The cross-sectional shape of the mounting cavity 111 can be flexibly set according to actual design requirements, including but not limited to polygons such as circles, regular hexagons, squares, and trapezoids.

[0049] The auxiliary head 120 serves as the carrier for the beauty component 121. Its shape is perfectly matched to the mounting cavity 111 of the main body 110. Specifically, the cross-sectional shape of the auxiliary head 120 is identical to that of the mounting cavity 111, and the variation trend of the cross-sectional dimensions of the auxiliary head 120 along its length perfectly matches the variation trend of the cross-sectional area of ​​the mounting cavity 111. For example, if the mounting cavity 111 is a gradually changing circular cavity, the auxiliary head 120 has a frustum-shaped structure, ensuring that the auxiliary head 120 can be smoothly inserted into the mounting cavity 111 along the opening 112 and fits tightly against the inner wall of the mounting cavity 111 after insertion. The beauty component 121 mounted on the auxiliary head 120 is configured according to functional requirements, including but not limited to hair removal components, photon skin rejuvenation components, ultrasonic induction components, and current care components.

[0050] The auxiliary head 120 is divided into a first end and a second end arranged opposite to each other along its length. The first end is the insertion end. The overall length of the auxiliary head 120 is adapted to the depth of the mounting cavity 111. That is, after the first end is fully inserted into the mounting cavity 111, the end face can fit against the bottom wall of the mounting cavity 111 to realize the structural connection and functional docking between the auxiliary head 120 and the body 110. For example, the first end of the auxiliary head 120 is provided with a conductive terminal, which contacts the conductive contact provided on the bottom wall of the mounting cavity 111. The second end is the exposed end. After the first end is inserted into the mounting cavity 111, the second end is always exposed outside the cavity opening 112 of the body 110, which facilitates the user to insert and remove the auxiliary head 120.

[0051] The installation principle of the auxiliary head 120 is as follows:

[0052] The user holds the second end of the auxiliary head 120 and aligns the first end with the cavity 112 of the body 110 (precise alignment is not required, because the mounting cavity 111 has a gradient structure and the size of the cavity 112 is larger than the size of the first end, which has a certain degree of centering tolerance).

[0053] Pushing the auxiliary head 120 towards the bottom wall of the mounting cavity 111, the first end of the auxiliary head 120 automatically fits against the inner wall of the mounting cavity 111 during insertion, generating pressure on the inner wall in the insertion direction. This increased pressure leads to increased friction between the outer peripheral wall of the auxiliary head 120 and the inner wall of the mounting cavity 111. Furthermore, as the insertion depth increases, the contact area between the auxiliary head 120 and the mounting cavity 111 gradually increases, resulting in a tighter fit. Once the auxiliary head 120 is fully inserted, the self-locking characteristic of the wedge fit kicks in. Due to the gradual change in cross-sectional area of ​​the mounting cavity 111, the pressure exerted on the cavity wall by the auxiliary head 120 increases along the depth direction, creating a stable frictional force. This reduces the likelihood of the auxiliary head 120 dislodging itself without external force, achieving reliable fixation.

[0054] The disassembly principle of the auxiliary head 120 is as follows:

[0055] During disassembly, the user simply holds the second end of the accessory head 120 and applies a pulling force away from the bottom wall of the mounting cavity 111. The pulling force only needs to overcome the friction of the wedge fit, such as 1N to 3N, which is ergonomically designed and does not require excessive force. Because the mounting cavity 111 has a gradient structure, under the action of the pulling force, the first end of the accessory head 120 will smoothly detach along the cavity wall without jamming or sudden changes in resistance.

[0056] In this embodiment of the beauty device 100, the auxiliary head 120 is adapted to the mounting cavity 111 on the body 110 and is detachably disposed in the mounting cavity 111 via the cavity opening 112. The first end of the auxiliary head 120 is inserted into the mounting cavity 111, and the second end is exposed at the cavity opening 112. The cross-sectional area of ​​the mounting cavity 111 gradually decreases along the direction of the cavity opening 112 toward its bottom wall, so that the outer side wall of the auxiliary head 120 and the inner side wall of the mounting cavity 111 have a wedge-shaped fit. The auxiliary head 120 can be easily inserted into the mounting cavity 111 during installation without precise alignment, simplifying the operation steps and saving time. The disassembly process is also convenient, reducing the difficulty of operation. At the same time, compared with the snap-fit ​​structure, while ensuring the stability of the connection, the wedge-shaped fit avoids damage problems such as snap hook breakage and deformation caused by complex operation, ensuring normal use of the device and improving the ease of use and maintenance flexibility of the beauty device 100.

[0057] In some embodiments, refer to Figure 3 and Figure 4 The body 110 is equipped with a heat conduction component, which is exposed on the inner wall of the mounting cavity 111, providing a contact basis for heat transfer; the beauty component 121 is mated and fitted with the heat conduction component. Specifically, the beauty component 121 is correspondingly arranged with the heat conduction component on the side of the body 110, so as to form a mating fit after assembly to achieve heat transfer.

[0058] The heat conduction component can be used for cold compresses, meaning it absorbs heat from the beauty component 121, causing a cooling sensation. When the beauty device 100 comes into contact with the skin, it can provide cold compress treatment. Alternatively, the heat conduction component can be used for hot compresses, meaning it transfers heat to the beauty component 121, causing a warming sensation. When the beauty device comes into contact with the skin, it can provide hot compress treatment. The structure and function of the heat conduction component can be set according to actual conditions, and this embodiment does not limit this.

[0059] The core improvement of this solution lies in the matching structure design of the mounting cavity 111 of the body 110 and the auxiliary head 120. Through the gradient cross-section design of the mounting cavity 111, the outer wall of the auxiliary head 120 and the inner wall of the mounting cavity 111 form a wedge fit. The self-tightening characteristics of the wedge structure generate a tight squeezing force, thereby ensuring the fit between the beauty component 121 and the heat conduction component.

[0060] The user inserts the auxiliary head 120 into the cavity 112 of the body 110. Since both the mounting cavity 111 and the auxiliary head 120 are similar to conical structures, they form a wedge fit. During insertion, the inner wall of the mounting cavity 111 generates a uniform radial constraint force on the outer wall of the auxiliary head 120. This constraint force guides the auxiliary head 120 to move along the axial direction of the mounting cavity 111. As the insertion depth increases, the squeezing force of the wedge structure gradually increases. When the auxiliary head 120 is inserted to the bottom of the mounting cavity 111, the squeezing force reaches a stable value, so that the beauty component 121 and the heat conduction component form a tight fit without gaps. While completing the assembly and positioning, it realizes the reliable and tight docking of the heat conduction interface, improves the heat conduction efficiency, and ensures the beauty effect.

[0061] In some embodiments, refer to Figure 3 and Figure 4 The body 110 has a first end face D1 and a first side face C1 that are connected to each other. The cavity 112 is located on the first end face D1. The insertion and removal direction of the auxiliary head 120 is perpendicular to the first end face D1.

[0062] The mounting cavity 111 extends through the first side surface C1 and forms a first opening 113 on the first side surface C1. The auxiliary head 120 has a light-emitting surface 120M and a light-emitting port 120K located at the light-emitting surface 120M. The light-emitting surface 120M is exposed at the first opening 113.

[0063] In this embodiment, the fuselage 110 is generally square in shape, having a first end face D1 and a first side face C1 that are perpendicular to each other and integrally formed. The first end face D1 is the end plane of the fuselage 110, preferably a square face, the size of which is adapted to the main body size of the fuselage 110, serving as the bearing surface of the cavity 112. The first side face C1 is the circumferential sidewall of the fuselage 110, extending along the length of the fuselage 110, and is connected to the first end face D1 by an arc transition or a right angle transition.

[0064] The cavity 112 is located on the side (or center) of the first end face D1. The shape of the cavity 112 matches the cross-sectional shape of the mounting cavity 111, and its size matches the maximum cross-sectional size of the mounting cavity 111, ensuring smooth insertion of the auxiliary head 120. The insertion / removal direction of the auxiliary head 120 is perpendicular to the first end face D1. That is, when inserting the auxiliary head 120, the user needs to apply force in a direction perpendicular to the first end face D1 (if the first end face D1 is the top surface of the body 110, the insertion / removal direction is "vertical axis"). This direction is the same as the extension direction of the first side surface C1 of the body 110, forming a spatial layout of end-face insertion / removal and side-face light emission. The user can easily insert or remove the auxiliary head 120 by holding the circumferential side wall of the body 110 and at the end of the body 110.

[0065] The mounting cavity 111, based on the wedge-shaped gradient cavity, extends radially through the first side surface C1 of the body 110, forming a rectangular first opening 113 on the first side surface C1. The shape of the first opening 113 on the side surface is consistent with the shape of the light-emitting surface 120M of the auxiliary head 120 (if the light-emitting surface 120M is rectangular, the first opening 113 is also rectangular). After the auxiliary head 120 is inserted into the mounting cavity 111, its light-emitting surface 120M is precisely aligned with the first opening 113 of the first side surface C1 of the body 110 and is exposed in the first opening 113. With the light-emitting surface 120M exposed in the first opening 113 of the first side surface C1, the user only needs to face the first side surface C1 towards the skin, and the light-emitting surface 120M can directly adhere to the skin without flipping the body 110 or adjusting the hand angle, making it convenient to use.

[0066] In some embodiments, refer to Figure 3 and Figure 4 The mounting cavity 111 has three inner sidewalls located between the bottom wall and the cavity opening 112 and connected in sequence. The width of at least one of the inner sidewalls gradually decreases along the direction from the cavity opening 112 toward the bottom wall, and the width direction of the inner sidewall is perpendicular to the insertion and removal direction of the accessory head 120.

[0067] The accessory head 120 has a first end wall, a second end wall, and four outer side walls located between the first end wall and the second end wall and connected in sequence. The first end wall is located at the first end, and the second end wall is located at the second end. The width of at least one of the outer side walls gradually decreases along the direction from the second end towards the first end.

[0068] The mounting cavity 111 has a cavity structure consisting of a bottom wall, circumferential side walls, and a cavity opening 112. Its circumferential side walls are composed of three sequentially connected inner side walls. These three inner side walls, together with the side wall containing the first opening 113, enclose the circumferential boundary of the mounting cavity 111, and are all located between the bottom wall and the cavity opening 112. The width direction of the inner side walls is defined as radial, perpendicular to the insertion / removal direction of the accessory head 120. At least one inner side wall has a width that gradually decreases along the direction from the cavity opening 112 towards the bottom wall. The remaining inner side walls can be set to a uniform width or an adaptive gradient structure to ensure that the overall shape of the mounting cavity 111 matches the shape of the accessory head 120.

[0069] The accessory head 120 is provided with a first end wall (located at the first end, facing the bottom wall when inserted into the mounting cavity 111) and a second end wall (located at the second end, exposed at the cavity opening 112) along the axial direction. It is composed of four sequentially connected outer side walls (enclosing to form the circumferential outline of the accessory head 120 and located between the first and second end walls). The width of at least one of the outer side walls gradually decreases along the direction from the second end to the first end. Its gradient trend and width dimension are adapted to the gradient inner side wall of the mounting cavity 111, ensuring that the outer side wall and the inner side wall fit tightly and the insertion and removal are smooth when the accessory head 120 is inserted.

[0070] In this embodiment, the inner sidewall of the mounting cavity 111 with its gradually changing width forms a wedge-shaped guide fit with the corresponding outer sidewall of the accessory head 120. When the accessory head 120 is inserted, it does not need to be precisely aligned in the circumferential position, as the gradually changing sidewall can automatically guide and position it.

[0071] In some embodiments, refer to Figure 3 The fuselage 110 has a mounting portion 110A at one end, which protrudes from the side of the fuselage 110. At least a portion of the mounting cavity 111 is formed in the mounting portion 110A.

[0072] In this embodiment, a mounting portion 110A is formed at one end of the fuselage 110 near the first end face D1 (i.e., the end face where the cavity 112 is located), along a direction perpendicular to the length of the fuselage 110 (i.e., the radial direction of the fuselage 110). The mounting portion 110A protrudes outward from the side of the fuselage 110, forming an asymmetrical structure between the main body of the fuselage 110 and the partially protruding mounting portion 110A. This can be achieved by either a portion of the mounting cavity 111 being formed in the mounting portion 110A, or by the entire mounting cavity 111 being formed in the mounting portion 110A, depending on actual requirements. By constructing the protruding mounting portion 110A as a carrier for the mounting cavity 111, the fuselage 110 can reserve more space in its main body to accommodate core components, such as a large-size cooling fan, thereby improving heat dissipation performance. Furthermore, the mounting part 110A only protrudes partially at one end of the body 110. The main body of the body 110, except for the mounting part 110A, maintains a uniform shape in other areas. When the user holds the device, the mounting part 110A can naturally isolate the hand from the light outlet 120K to avoid blocking the emitted light and affecting the beauty effect.

[0073] In some embodiments, refer to Figure 3 and Figure 4 The two opposite sides of the second end are respectively provided with a fastening part 122. The fastening part 122 extends outward and bends to form a fastening groove 122C. The corresponding side of the cavity 112 is inserted into the fastening groove 122C.

[0074] In this embodiment, the second end of the accessory head 120 has a fastening portion 122 formed on its opposite sides along the radial direction. Specifically, the fastening portion 122 extends horizontally outward from the side of the second end, and the end of the extension is bent in the direction toward the first end to form a U-shaped fastening groove 122C. The fastening groove 122C is shaped with an opening toward the cavity 112 and can accommodate the corresponding side of the cavity 112.

[0075] When the auxiliary head 120 is inserted into the mounting cavity 111, it achieves positioning and fit through a wedge-shaped engagement. It continues to be pushed in until the latching part 122 at the second end contacts the side of the cavity opening 112, and finally, the latching groove 122C engages with the side of the cavity opening 112. When pulling it out, a slight force deforms the latching part 122, causing the latching groove 122C to disengage from the side of the cavity opening 112, and then it smoothly disengages along the guide of the wedge-shaped engagement. The latching engagement between the latching groove 122C and the side of the cavity opening 112 enhances the installation stability of the auxiliary head 120.

[0076] In some embodiments, refer to Figure 3 and Figure 4 The second end also has pinching portions 123 on its opposite sides, and the surface of the pinching portions 123 is provided with a textured structure; or,

[0077] The inner wall of the mounting cavity 111 is provided with a magnetic attractor, which is used to magnetically attract the auxiliary head 120.

[0078] In this embodiment, optionally, the second end of the auxiliary head 120 is further configured with gripping portions 123 on its radially opposite sides. Specifically, the gripping portions 123 are protruding structures and are integrally injection molded with the second end. The surface of the gripping portions 123 is provided with anti-slip textures, which can be horizontal textures or diagonal cross textures, etc., depending on actual needs. The gripping portions 123 can be offset from the fastening portions 122 to avoid the deformation area of ​​the fastening portions 122. The user can operate the insertion or removal of the auxiliary head 120 from the mounting cavity 111 by gripping the gripping portions 123 at the second end of the auxiliary head 120.

[0079] Optionally, a magnetic attractor may be provided within the mounting cavity 111 of the housing 110, located on the inner wall of the mounting cavity 111. For example, the magnetic attractor may be a magnet, one or more of which are embedded in a pre-set groove on the inner wall, with the surface of the magnetic attractor flush with the inner wall. The outer wall of the accessory head 120 is provided with a magnetically attractable metal sheet corresponding to the position of the magnetic attractor. When the accessory head 120 is inserted into the mounting cavity 111, the magnetic attractor magnetically attracts the accessory head 120 (e.g., the metal sheet on the accessory head 120), and the resulting magnetic force helps to fix the accessory head 120 within the mounting cavity 111.

[0080] In some embodiments, refer to Figure 3 and Figure 4 The auxiliary head 120 is provided with a light outlet 120K and a second opening 120A. The second opening 120A and the light outlet 120K are located on different outer side walls of the auxiliary head 120. The beauty component 121 includes a light-transmitting element 1211, which is installed in the light outlet 120K and exposed through the second opening 120A.

[0081] The heat conduction components include:

[0082] The cooling component 130 is aligned with the second opening 120A and is in contact with the light-transmitting component 1211.

[0083] In this embodiment, the outer wall of the auxiliary head 120 is provided with a light-emitting port 120K and a second opening 120A, which are located on different side walls. For example, the light-emitting port 120K is located on the side wall of the auxiliary head 120 facing the first opening 113 of the first side C1, for emitting light. The second opening 120A is located on the other side wall adjacent to the side wall where the light-emitting port 120K is located, facing the inner side wall of the mounting cavity 111, to ensure no functional interference. The light-transmitting element 1211 of the beauty component 121 is adapted to be installed in the light-emitting port 120K for allowing light to pass through, and part of the light-transmitting element 1211 extends to and is exposed through the second opening 120A.

[0084] The cooling component 130 is fixed to the inner wall of the mounting cavity 111 of the body 110 and precisely aligned with the second opening 120A of the auxiliary head 120. After the auxiliary head 120 is inserted into the mounting cavity 111, the cooling surface of the cooling component 130 directly contacts the exposed portion of the light-transmitting element 1211 through the second opening 120A. The light-transmitting element 1211 is prone to heating under the action of beauty energy (such as light energy). By cooling the light-transmitting element 1211 through the cooling component 130, cold compress care of the skin can be achieved, avoiding burns and ensuring safety during use. Furthermore, the cooling component 130 is integrated into the body 110 rather than the auxiliary head 120, resulting in low operating costs if the auxiliary head 120 is damaged and needs replacement.

[0085] In some other embodiments, the light-transmitting element 1211 can also be used to conduct heat to the skin for hot compresses. It is understood that when light transmission is not required, a skin-adhesive element can be installed at the location where the light-transmitting element 1211 is installed. This skin-adhesive element can be made of ceramic or metal and is used to conduct heat or cold flow to the skin to achieve hot or cold compresses.

[0086] In some embodiments, refer to Figure 4 and Figure 5 The inner side of the mounting cavity 111 is provided with a mounting port 1111, and the cooling assembly 130 includes:

[0087] A cooling pad 131 is provided with a first thermally conductive silicone sheet 1311 attached to the side of the cooling pad 131 facing the second opening 120A;

[0088] The heat-conducting element 132 is movably disposed on the side of the cooling plate 131 facing the second opening 120A, and the heat-conducting element 132 protrudes from the inner wall of the mounting cavity 111 through the mounting port 1111. The light-transmitting element 1211 presses the heat-conducting element 132 so that the heat-conducting element 132 abuts against the first thermally conductive silicone sheet 1311.

[0089] In this embodiment, an installation port 1111 is formed on the inner wall of the mounting cavity 111 at the position corresponding to the second opening 120A of the auxiliary head 120. The installation port 1111 can be rectangular or the like, adapted to the shape of the heat-conducting component 132. The cooling element 131 is fixed inside the body 110 and aligned with the installation port 1111. The cooling element 131 can be a semiconductor cooling element 131, which is electrically connected to the control system of the beauty device 100. The side of the semiconductor cooling element 131 facing the second opening 120A is the cold side, which completely adheres to the first thermally conductive silicone sheet 1311. The other side of the cooling element 131 facing away from the second opening 120A is the hot side. When the semiconductor cooling element 131 is powered on, heat is transferred from its cold side to its hot side.

[0090] When the auxiliary head 120 is inserted into the mounting cavity 111, the light-transmitting element 1211 of the auxiliary head 120 moves synchronously with the second opening 120A to align with the mounting opening 1111. As the auxiliary head 120 continues to be pushed in, the light-transmitting element 1211 contacts the end of the heat-conducting element 132 protruding from the mounting cavity 111 and applies pressure, pushing the heat-conducting element 132 along the axial direction of the mounting opening 1111 towards the cooling element 131, until the other end of the heat-conducting element 132 is completely pressed against the first thermally conductive silicone sheet 1311, forming a thermally conductive path of light-transmitting element 1211 - heat-conducting element 132 - first thermally conductive silicone sheet 1311 - cooling element 131. When the auxiliary head 120 is pulled out of the mounting cavity 111, the heat-conducting element 132 loses its pressure and can reset under the elastic action of the first thermally conductive silicone sheet 1311, protruding from the inner wall of the mounting cavity 111.

[0091] During the use of the beauty device 100, the heat on the light-transmitting component 1211 can be transferred to the cold side of the cooling plate 131 via the heat-conducting component 132 and the first heat-conducting silicone sheet 1311. By activating the cooling plate 131, the heat from the cold side is transferred to the hot side, thereby achieving rapid heat dissipation of the light-transmitting component 1211. When the auxiliary head 120 is inserted into the mounting cavity 111, the light-transmitting component 1211 presses against the heat-conducting component 132 and the first heat-conducting silicone sheet 1311, eliminating gaps between components, reducing thermal resistance in the heat conduction path, and ensuring efficient heat dissipation. Simultaneously, the auxiliary head 120 can be tightened within the mounting cavity 111, improving the stability of the auxiliary head 120's installation.

[0092] In some embodiments, refer to Figures 5 to 7 The heat-conducting component 132 includes a heat-conducting cover 1321, which includes a main body 13211 and a protruding edge 13212 protruding from the edge of the main body 13211.

[0093] The main body 13211 protrudes from the inner wall of the mounting cavity 111 through the mounting port 1111. The edge of the mounting port 1111 limits the protruding edge 13212 to prevent the heat conduction cover 1321 from detaching from the mounting port 1111. The body 110 is provided with a space 114 for the protruding edge 13212 to move, so that the heat conduction cover 1321 can be movably covered on the first heat conduction silicone sheet 1311.

[0094] In this embodiment, the heat-conducting cover 1321 is integrally formed and includes a main body 13211 and a protruding edge 13212. The main body 13211 is a cover-shaped structure adapted to the mounting opening 1111 for direct contact and heat transfer with the light-transmitting element 1211. The protruding edge 13212 protrudes vertically outward along the outer peripheral edge of the main body 13211, forming a limiting structure. For example, two protruding edges 13212 are provided, respectively located on opposite sides of the main body 13211 along its length direction. The mounting opening 1111 on the inner sidewall of the mounting cavity 111 is an opening adapted to the main body 13211, through which the main body 13211 passes and protrudes into the mounting cavity 111. The edge of the mounting opening 1111 forms a stepped surface, and the protruding edge 13212 can overlap this stepped surface. The stepped surface prevents the protruding edge 13212 from moving into the mounting cavity 111, thereby restricting the heat-conducting cover 1321 from detaching from the mounting opening 1111. At the same time, a movable space 114 is reserved inside the body 110 corresponding to the position of the protruding edge 13212, so that the heat-conducting cover 1321 can move flexibly along the axial direction of the mounting opening 1111 and always cover the outside of the first thermally conductive silicone sheet 1311.

[0095] When the auxiliary head 120 is inserted into the mounting cavity 111, the light-transmitting element 1211 moves with the auxiliary head 120 and presses the main body 13211 of the heat-conducting cover 1321, pushing the main body 13211 inward toward the mounting opening 1111, and causing the main body 13211 to be tightly pressed against the cooling chip 131 through the first thermally conductive silicone sheet 1311. When the auxiliary head 120 is pulled out of the mounting cavity 111, under the elastic action of the first thermally conductive silicone sheet 1311, the main body 13211 protrudes outward from the mounting opening 1111. At the same time, under the limiting action of the edge of the mounting opening 1111 on the protruding edge 13212, the heat-conducting cover 1321 is restricted from detaching from the mounting opening 1111 in the direction toward the mounting cavity 111.

[0096] In some embodiments, refer to Figures 5 to 7 The beauty device 100 also includes:

[0097] The heat dissipation assembly 140 is located inside the body 110. The heat dissipation assembly 140 includes a heat dissipation fan 141, heat dissipation fins 142 and heat dissipation component 143. The heat dissipation fins 142 are arranged opposite to the air inlet or air outlet of the heat dissipation fan 141. The heat dissipation component 143 is connected to the heat dissipation fins 142 and is also connected to the cooling chip 131.

[0098] In this embodiment, the heat dissipation component 140 is integrated inside the housing 110, working in conjunction with the cooling component 130 to achieve thermal management. The heat dissipation component 143 is made of a high thermal conductivity material (such as copper or aluminum), and has a tubular or block-shaped structure. One end is directly (or through a second thermally conductive silicone pad 1312) tightly attached to the hot surface of the cooling plate 131, while the other end is welded to or integrally formed with the heat dissipation fins 142, enabling rapid heat conduction. The heat dissipation fins 142 have an array-type thin-plate structure; the number of fins and the spacing between them can be set according to actual needs, and this embodiment does not impose any limitations on this. A cooling fan 141 is installed inside the housing 110 on one side corresponding to the heat dissipation fins 142, with its air inlet or outlet facing the end face of the heat dissipation fins 142, forming a directional airflow channel. Heat dissipation holes are provided on the side wall of the housing 110 corresponding to the location of the cooling fan 141, allowing air circulation inside and outside the housing 110.

[0099] When the cooling chip 131 is powered on, the cooling fan 141 starts, drawing air through the gaps in the heat sink fins 142 to quickly carry away the heat (generated at the hot end of the cooling chip 131) from the body 110, forming a complete heat dissipation path: the hot end of the cooling chip 131 → the heat sink 143 → the heat sink fins 142 → the fan → outside the body 110.

[0100] In some embodiments, refer to Figure 8 The beauty component 121 also includes a light-emitting element 1212, a light-filtering element 1213, and a reflective element 1214;

[0101] The light-emitting element 1212 is disposed opposite to the light-emitting port 120K, the filter element 1213 is located between the light-emitting element 1212 and the light-transmitting element 1211, and the reflector element 1214 is covered on the side of the light-emitting element 1212 away from the light-emitting port 120K, so as to reflect the light projected onto it toward the light-emitting port 120K.

[0102] In this embodiment, the light-emitting element 1212 can be a lamp tube. In actual installation, the lamp tube is arranged relative to the light outlet 120K, and the plane of the lamp tube is parallel to the plane of the light outlet 120K. Further, the lamp tube can be a halogen lamp tube, a xenon lamp tube, etc. The light filter 1213 can be a filter plate or filter sheet, used to filter the light emitted by the light-emitting element 1212 to obtain light of a specific wavelength. The reflector 1214 can be a reflector, which is arc-shaped. The side of the reflector facing the light-emitting element 1212 is formed as a reflective surface. The light projected by the light-emitting element 1212 onto the reflective surface of the reflector is reflected towards the light outlet 120K through the reflective surface of the reflector.

All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
