[0042] This utility model proposes an auxiliary head, referring to... Figures 1 to 6 The accessory head 800 includes:

[0043] A cover 100 is detachably connected to the main body 701 of the skin care device 700. The cover 100 includes a first end face 110, a second end face 120 spaced apart from the first end face 110, and a peripheral side portion 130 connected between the first end face 110 and the second end face 120. The periphery of the peripheral side portion 130 gradually expands along the direction from the first end face 110 to the second end face 120. The first end face 110 and the peripheral side portion 130 form a cavity 140 for the cover 100 to cover the main body 701 of the skin care device 700.

[0044] The cosmetic assembly 200 is arranged on the cover 100 and is used for skin care.

[0045] The skin care device refers to a machine capable of improving and adjusting human skin according to human physiological functions. According to the cosmetic effect, the skin care device includes but is not limited to a depilating instrument, a whitening instrument, a skin tenderizing instrument, a wrinkle removing instrument, a freckle removing instrument, etc. In some embodiments, one skin care device can have one or more cosmetic effects. For example, one skin care device can have the effects of depilation and skin tenderizing at the same time, or the effects of depilation, whitening and skin tenderizing at the same time.

[0046] The main body 701 of the skin care device 700 is a working end for playing a main function, which can also be referred to as a working head. For example, as shown in the figure, Figure 1 When the accessory head 800 is mounted on the main body 701, the cover 100 is arranged on the main body 701, and at this time, the skin care device completes the skin care work through the accessory head 800. In the utility model, the accessory head 800 is detachably connected with the main body 701 through the cover 100. When a user needs to use the accessory head 800 to care for the skin, the accessory head 800 can be directly mounted on the main body 701, and the skin is cared for through the cosmetic assembly 200 on the accessory head 800. When the user does not need to use the accessory head 800 or needs to directly use the main body 701 of the skin care device to care for the skin, the accessory head 800 can be detached from the main body 701.

[0047] Referring to Figure 4 and Figure 6 , the cover 100 includes a first end face 110, a second end face 120 and a peripheral side part 130 between the two, the second end face 120 is an annular face, so that the cover 100 is enclosed to form a concave cavity 140 with an opening, so that at least part of the main body 701 is accommodated in the concave cavity 140, and then the fixation between the accessory head 800 and the skin care device is completed. The shape of the second end face 120 and the concave cavity 140 can be set according to design requirements. For example, the thickness of each position of the peripheral side part 130 can be controlled, so that the side wall of the concave cavity 140 is fitted with the outer surface of the main body 701, and the stability after the accessory head 800 is mounted is improved.

[0048] The size and shape of the first end face 110 are related to the effect to be achieved by the accessory head 800. If the accessory head 800 acts on a smaller skin area, such as the arm, forehead and other parts, the area of the first end face 110 is usually smaller, and can be set as a curved surface with a certain curvature according to the different parts. Correspondingly, if the accessory head 800 acts on a larger skin area, such as the thigh, cheek and other parts, the area of the first end face 110 can be enlarged.

[0049] The peripheral side 130 of the cover body 100 extends from the first end surface 110 to the second end surface 120 with a tendency of gradually expanding in the periphery, that is, the cover body 100 as a whole has a stepped shape with a narrow upper part and a wide lower part, which can be a regular circular or prismatic frustum, or an irregular shape. Since the second end surface 120 surrounded by the ring has a larger area, that is, the opening of the cavity 140 is larger, the user can more conveniently install the accessory head 800 on the skin care device, and the smaller first end surface 110 also facilitates the user to care for the skin in a smaller area.

[0050] The accessory head 800 is detachably connected to the skin care device through the cover body 100. There are various ways of detachable connection, for example, the connection part of the cover body 100 and the main body 701 is provided with a threaded structure, and the cover body 100 is screwed onto the main body 701 by rotation, thereby forming a stable connection, and the reverse rotation can complete the disassembly, which is simple to operate and firm in connection; or a socket is provided on the side wall of the cavity 140, and a plug is provided on the corresponding part of the skin care device, and the plug and the socket are matched to form a stable connection, which is simple in structure and low in cost; or reusable adhesive material such as Velcro can be used to connect the cover body 100 and the main body 701, which is more convenient to use.

[0051] The cosmetic assembly 200 is a structure for caring for the skin on the accessory head 800, which can be a structure for assisting the main body 701 to achieve the cosmetic effect, or a structure for directly achieving the cosmetic effect, and the arrangement of the cosmetic assembly 200 will change according to the different functions. For example, if the skin care device is a hair removal instrument that achieves hair removal by light irradiation, the cosmetic assembly 200 can only be a filter, which is accommodated in a hole formed in the cover body 100, so that the strong pulsed light emitted by the main body 701 needs to be filtered by the filter before irradiating the skin, filtering out the light (such as ultraviolet light) harmful to the human body, or filtering different wavelengths of light for different parts of the skin, adjusting the heating effect on different depths of hair follicles, thereby achieving different hair removal effects more targetedly; if the skin care device is a micro-current cosmetic instrument, the micro-current can stimulate facial muscles, and the cosmetic assembly 200 can be a discharge structure arranged on the first end surface 110, which is electrically connected to the skin care device when the accessory head 800 is installed on the main body 701, so that the discharge structure on the accessory head 800 cares for the skin.

[0052] The utility model discloses technical scheme through the detachable connection of accessory head 800 and skin care equipment, so that the user can adjust the function of skin care equipment through the mode of installing accessory head 800, so that skin care equipment can carry out targeted nursing to the skin of different parts, and the human and material resources cost of user purchase, carrying multiple skin care equipment is reduced, the periphery of the circumferential side part 130 of cover body 100 gradually expands along the direction of first end surface 110 extending to second end surface 120, and the larger size of second end surface 120 makes the opening of recess cavity 140 of accessory head 800 larger, so that the user can more easily set accessory head 800 on main body 701, and smaller first end surface 110 is convenient for the user to nurse the skin of smaller area, meanwhile, the distance of main body 701 extending into accessory head 800 is larger, and the distance between the light emitting part on main body 701 and the light transmission piece 220 on accessory head 800 is smaller, and the light loss of the light emitting part on main body 701 irradiating to the skin through the light transmission piece 220 on accessory head 800 is smaller.

[0053] As shown in Figure 2 and Figure 4 In some embodiments, the cosmetic assembly 200 includes a plurality of electrodes 210, which are spaced apart on the first end surface 110, and the outer edge of the first end surface 110 is a polygon with more than four sides.

[0054] Since the electrodes 210 are usually required to be symmetrically arranged on the first end surface 110, the outer edge of the first end surface 110 is set as a polygon, which facilitates the positioning and installation of the electrodes 210, so that the current generated after the two corresponding electrodes 210 come into contact with the skin can pass through and stimulate the skin, completing the nursing of the skin. At the same time, the first end surface 110 with a polygonal outer edge also facilitates the arrangement of the electrodes 210 with a polygonal outer edge, that is, the opposite edges between the two opposite electrodes 210 are straight lines, which not only makes the arrangement of the electrodes 210 more compact, but also facilitates the generation of regular current, ensuring the cosmetic effect.

[0055] Further, a plurality of edges can be extended from the vertices of the first end surface 110, so that the outer surface of the cover body 100 is divided into a plurality of surfaces, which not only facilitates the placement of the accessory head 800, but also provides a larger friction force, facilitating the user to hold, and the user can more easily adjust the direction and angle of the accessory head 800, and perform more accurate nursing. Preferably, the outer edge of the first end surface 110 is a regular octagon, which makes the accessory head 800 look more regular, improves the overall appearance of the accessory head 800, and compared with a polygon with fewer sides, the regular octagon has a larger area and a larger contact surface with the skin, thereby improving the cosmetic efficiency.

[0056] As shown in Figure 4 and Figure 5As shown, in some embodiments, the peripheral side 130 comprises a first ring portion 131 and a second ring portion 132 connected in sequence, the first ring portion 131 comprises a plurality of first side faces 131a connected in sequence in the circumferential direction, and the second ring portion 132 comprises a plurality of second side faces 132a connected in sequence in the circumferential direction and corresponding to the first side faces 131a, one end of each first side face 131a is connected to one end of a corresponding second side face 132a, and the other end of the first side face 131a is connected to an edge of the first end face 110;

[0057] Wherein, the first side face 131a is an inclined plane or curved surface extending from the first end face 110 to the second side face 132a, and the second side face 132a is an inclined plane or curved surface extending from the first side face 131a to the edge of the second end face 120.

[0058] The peripheral side 130 of the accessory head 800 is gradiently arranged, that is, through the segmented design of the first ring portion 131 and the second ring portion 132, the gravity distribution of the accessory head 800 can be controlled by controlling the extension length of the first ring portion 131 and the second ring portion 132, so as to improve the stability of the accessory head 800, and the accessory head 800 can also be arranged in a shape convenient for the user to hold, thereby improving the user experience. At the same time, the first ring portion 131 and the second ring portion 132 divide the cover body 100 into different areas, which facilitates planning the installation positions of different components on the accessory head 800, for example, the first ring portion 131 is used for installing the beauty assembly 200, and the second ring portion 132 is used for installing a connecting assembly connected with the main body 701, so that the structural design of the accessory head 800 is more reasonable and compact.

[0059] The first ring portion 131 and the second ring portion 132 also make the change in the shape of the accessory head 800 between the first end face 110 and the second end face 120 more smooth, which helps to reduce stress concentration and avoid breakage or wear caused by impact during use, thereby prolonging the service life of the accessory head 800. Moreover, the gradient design makes the appearance of the accessory head 800 more hierarchical, has a three-dimensional sense and aesthetic appearance, and increases the visual appeal of the product.

[0060] If the first side face 131a and the second side face 132a are inclined planes, the vertical distance between the first end face 110 and the second end face 120 and the size of the cavity 140 can be adjusted by controlling the slope, and the design and manufacture of the cover body 100 are relatively simple; if the first side face 131a and the second side face 132a are curved surfaces, the wear and stress concentration of the cover body 100 can be reduced, and the service life of the accessory head 800 is further prolonged. It can be understood that the first side face 131a and the second side face 132a can both be curved surfaces, or both be planes, or one be a curved surface and the other be a plane, which can be set according to actual needs, and the utility model does not limit this.

[0061] As shown in the drawings, in some embodiments, the first side surface 131a is a curved surface recessed from the middle of the first side surface 131a to the edge of the second side surface 132a and the first end surface 110; and / or, Figures 2 to 4

[0062] The second side surface 132a is a curved surface recessed from the middle of the second side surface 132a to the opposite sides of the second side surface 132a connected with the second end surface 120.

[0063] The concave curved surface is more in line with the user's fingers when holding, allowing the user to more easily grasp the accessory head 800 and improving the user's experience. At the same time, the curved surface is also easier to disperse stress when impacted, which can largely avoid damage to the cover body 100. In addition, the concave curved surface occupies less space and is more aesthetically pleasing. It can be understood that the degree of recess of the first side surface 131a and the second side surface 132a can be set according to actual needs. If the recess is shallow, the effect of facilitating holding is not obvious enough. If the recess is deep, it will affect the strength of the cover body 100 at the recessed part. Therefore, taking the first side surface 131a as an example, the thickness of the thinnest part of the first side surface 131a is set to be greater than half the thickness of the thickest part of the first side surface 131a.

[0064] As shown in the drawings, in some embodiments, the periphery of the first ring part 131 gradually expands in the extension direction of the first end surface 110 to the second ring part 132, the periphery of the second ring part 132 gradually expands in the extension direction of the first ring part 131 to the second end surface 120, and the slope of the inner wall of the first ring part 131 is greater than the slope of the inner wall of the second ring part 132. Figure 3

[0065] Since the slope of the inner wall of the first ring part 131 is larger, the first ring part 131 can enclose a larger cavity, which is convenient for installing components such as the beauty assembly 200, and at the same time, the center of gravity of the cover body 100 is biased to the first end surface 110, which helps to increase the overall stability of the accessory head 800. The slope of the inner wall of the second ring part 132 is smaller, so that the second ring part 132 can further provide a supporting effect without rapidly increasing the space occupied by the cover body 100, thereby improving the portability of the accessory head 800.

[0066] As shown in the drawings, in some embodiments, the second end surface 120 is provided with a plurality of convex buckles 121, and the plurality of convex buckles 121 are used for buckle connection with the skin care equipment; and / or, Figure 1 Figure 6 A plurality of convex buckles 121 are arranged on the second end surface 120, and the plurality of convex buckles 121 are used for buckle connection with the skin care equipment.

[0067] The concave cavity 140 is provided with a magnetic attraction piece 141, and the magnetic attraction piece 141 is used for magnetic connection with the skin care equipment.

[0068] ​​​The protruding buckle 121 and the magnetic clasp 141 serve different connecting functions to ensure that the accessory head 800 can be securely installed on the skin care device. The protruding buckle 121 is a mechanical snap-fit ​​connector, which can be made of plastic or metal. Exemplarily, in this embodiment, one end of the protruding buckle 121 is disposed on the second end face 120, and the other end of the protruding buckle 121 is provided with a hook portion extending into the cavity 140. When the accessory head 800 is connected to the body 701 of the skin care device, the protruding hook portion can engage with the corresponding slot or hole on the skin care device, thereby fixing the relative position between the accessory head 800 and the skin care device. It is understood that there are various ways to connect the protruding buckle 121 to the first end face 110, such as welding, bonding, or threaded connection, or it can be integrally formed; this utility model does not limit this. Preferably, there are multiple protruding buckles 121, and the multiple protruding buckles 121 are symmetrically arranged on the second end face 120, thereby improving the connection strength between the accessory head 800 and the skin care device.

[0069] The magnetic element 141 is a magnet or an object that can be attracted by a magnet. Correspondingly, the skin care device is provided with a structure that can attract the magnetic element 141 to provide sufficient attraction when the accessory head 800 is installed on the skin care device. The number and position of the magnetic elements 141 can be selected according to actual needs. For example, in this embodiment, there are multiple magnetic elements 141, and the multiple magnetic elements 141 are evenly arranged around the first ring portion 131 to connect with the top of the main body 701. This can improve the stability of the connection and eliminate the need to connect the accessory head 800 and the main body 701 at a fixed angle, simplifying the installation steps of the accessory head 800. Of course, the magnetic element 141 can also be provided in the second ring portion 132, in which case the magnetic element 141 is usually connected to the side of the main body 701.

[0070] It is understandable that the protruding buckle 121 and the magnetic attachment 141 can be set at the same time, or only one of them can be set, depending on the actual needs.

[0071] like Figures 1 to 5 As shown, in some embodiments, the beauty component 200 includes a light-transmitting element 220. The first end face 110 has a light-transmitting hole 111 that penetrates the cover 100. The light-transmitting element 220 is disposed in the light-transmitting hole 111. The light-transmitting element 220 has a light-emitting end face 221 that is exposed outside the cover 100. The light-transmitting element 220 is used to allow light emitted from the body 701 to pass through when the auxiliary head 800 is connected to the main body 701 for skin care.

[0072] The light-transmitting hole 111 can be designed in a circular shape, an elliptical shape, a polygonal shape, or other irregular shapes, depending on the distribution requirements of the light.

[0073] The light-transmitting member 220 is made of a crystal material, such as sapphire, K9 glass, crystal glass, or other materials that meet the requirements of light-transmitting crystals. The shape and size of the light-transmitting member 220 are determined according to the light-transmitting hole 111. The light-transmitting member 220 is usually embedded in the light-transmitting hole 111 and tightly combined with the light-transmitting hole 111 through adhesion or interference fit, to prevent the light-transmitting member 220 from loosening or shifting. In actual use, the accessory head 800 is installed on the skin care device, and then the light-emitting structure in the skin care device is controlled to emit light, which passes through the light-transmitting hole 111 and the light-transmitting member 220 in the light-transmitting hole 111, and then is emitted from the light-emitting end face 221 and irradiated on the user's skin, thereby achieving skin care.

[0074] As shown in Figure 7 some embodiments, the light-transmitting member 220 includes a light-entering end face 222 opposite to the light-emitting end face 221, and a plurality of recesses 222a are arranged in a honeycomb pattern on the light-entering end face 222.

[0075] The honeycomb pattern of the recesses 222a means that a plurality of hexagonal recesses 222a are arranged in a close arrangement on the light-entering end face 222 of the light-transmitting member 220, and each recess 222a shares an edge with the surrounding recesses 222a, forming a honeycomb-like arrangement structure. The size and depth of the recesses 222a can be adjusted according to specific requirements. Generally, the diameter of the recesses 222a is small, to ensure that each recess 222a can effectively capture and guide the light, so that the light becomes more uniform when passing through the light-transmitting member 220. The depth of the recesses 222a can be designed according to the requirements of light refraction and reflection, to optimize the transmission effect of the light. Specifically, when the light-emitting structure in the skin care device emits light to the recesses 222a, the hexagonal structure of the honeycomb pattern of the recesses 222a guides the light to the light-emitting end face 221 of the light-transmitting member 220, thereby concentrating the light and improving the intensity and penetration of the light, to improve the cosmetic effect.

[0076] As shown in Figure 5 some embodiments, the first end face 110 is provided with a mounting plate 112, and the side of the mounting plate 112 opposite to the first end face 110 is formed with a plurality of mounting grooves 112a arranged at intervals. The cosmetic assembly 200 further includes a plurality of electrodes 210 arranged in the mounting grooves 112a. In use, at least part of the plurality of electrodes 210 can be in contact with the skin and output micro-current and / or radio frequency current to care for the skin.

[0077] The mounting plate 112 is arranged on the first end surface 110, and the electrodes 210 arranged on the mounting plate 112 are in contact with the skin. The shape of the mounting plate 112 can be arranged according to the design of the first end surface 110, so as to cover the required skin contact area of the electrodes 210. It can be understood that, since the light transmission hole 111 is arranged on the first end surface 110 to enable the light to pass through and irradiate the skin, a hole can also be arranged on the mounting plate 112 corresponding to the light transmission hole 111 to enable the light to pass through, thereby achieving multi-aspect care of the skin.

[0078] The mounting plate 112 can be fixed on the first end surface 110 in a non-detachable manner such as bolt connection or adhesion, and the connection is more firm and stable, or can be fixed on the first end surface 110 in a detachable manner such as magnetic connection or slot clamping, which is convenient for replacement or cleaning. In the embodiment, the mounting plate 112 can provide a stable surface to ensure that the electrodes 210 can uniformly contact the skin and avoid discomfort caused by uneven current distribution.

[0079] The number and size of the mounting grooves 112a on the mounting plate 112 are generally matched with the number and size of the electrodes 210, and each electrode 210 corresponds to a mounting groove 112a. Preferably, the mounting grooves 112a are uniformly distributed on the mounting plate 112 to ensure that the electrodes 210 can provide uniform current output, thereby improving the cosmetic effect. Further, in the embodiment, the mounting grooves 112a are arranged in four, and the four mounting grooves 112a are arranged around the light transmission hole 111, which can not only avoid the influence of the electrodes 210 on the light passing through the light transmission hole 111, but also ensure that the current output by the electrodes 210 is more uniform and is not easy to interfere with each other. The electrodes 210 can be fixed in the mounting grooves 112a by means of buckling, adhesion or threaded connection, and the utility model does not limit this. The electrodes 210 are fixed through the mounting grooves 112a, which ensures that they are not easy to shift or fall off during use, thereby ensuring the continuity and stability of skin care.

[0080] As shown in FIGS. Figure 3 and Figure 5 In some embodiments, the accessory head 800 further comprises an LED light strip 300, the LED light strip 300 is arranged in the recessed cavity 140, and the LED light strip 300 is used to form a light circle on the light transmission piece 220 to indicate the working state of the accessory head 800; and / or,

[0081] The accessory head 800 further comprises a circuit board 400, the circuit board 400 is arranged in the recessed cavity 140, and the plurality of electrodes 210 are respectively electrically connected with the circuit board 400.

[0082] The LED light strip 300 is housed within the recess 140 of the accessory head 800. This concealed installation not only protects the light strip from external environmental influences but also enhances the aesthetics of the accessory head 800. For example, in practical use, after the accessory head 800 is installed on the skin care device, the light-emitting structure in the skin care device emits light that passes through the light-transmitting element 220. Since this light is difficult to observe with the naked eye, the LED light strip 300 is activated along with the light-emitting structure. The light emitted by the LED light strip 300 is then visible to the user, clearly indicating that the skin care device is on, thus enhancing the user experience. Preferably, the LED light strip 300 can be designed to be monochrome or multi-color, allowing the skin care device to indicate different operating states or modes through different light colors and brightness levels, such as power-on, working, standby, charging, or malfunction. The intuitive visual feedback provided by the LED light strip 300 helps users understand the status of the skin care device in real time, improving ease of use.

[0083] Furthermore, the LED light strip 300 can be arranged around the light-transmitting element 220, so that the light emitted by the LED light strip 300 is evenly scattered on the light-transmitting element 220, forming a clear light ring and improving the visual prompting effect.

[0084] The electrode 210 on the accessory head 800 is connected to the circuit board 400, allowing the circuit board 400 to control the intensity and frequency of the microcurrent and / or radio frequency current output by the electrode 210. This enables precise current adjustment, ensuring that the current output by the electrode 210 meets the skincare requirements, thereby achieving a stable and effective skincare effect. Understandably, when the accessory head 800 is installed on a skincare device, the circuit board 400 is electrically connected to the skincare device, enabling the skincare device to control the electrode 210 on the accessory head 800.

[0085] like Figure 3 and Figure 5 As shown, in some embodiments, the auxiliary head 800 also includes a transparent glass element 500. The circuit board 400 has a mounting hole 410. The transparent glass element 500 is installed in the mounting hole 410 and covers the mounting hole 410. The transparent glass element 500, together with the inner wall of the peripheral side 130, the light-transmitting element 220, and the circuit board 400, form a sealed cavity 600. The LED light strip 300 is located inside the sealed cavity 600.

[0086] The mounting hole 410 on the circuit board 400 can be mounted with the transparent glass piece 500 for facilitating the light emitted by the skin care device to pass through. Meanwhile, the transparent glass piece 500 is arranged on the mounting hole 410 to cover the mounting hole 410 and enclose the sealed cavity 600, so that the LED lamp strip 300 is contained in the sealed cavity 600, and the dust, moisture or other impurities in the outside are prevented from entering the sealed cavity 600, thereby protecting the internal electronic components and the LED lamp strip 300. The transparent glass piece 500 can be arranged in the mounting hole 410 and adhesively or interference-fitted with the mounting hole 410, or can be arranged on the mounting hole 410, and the utility model does not limit this.

[0087] As shown in Figure 1 , Figure 3 In some embodiments, the accessory head 800 further comprises a magnetic member 141, and a through hole is arranged on the circuit board 400, the magnetic member 141 is arranged in the through hole, and a limiting groove 131b is arranged on the inner wall of the first ring part 131, one end of the magnetic member 141 is arranged in the limiting groove 131b, and the other end of the magnetic member 141 protrudes out of the circuit board 400 and is used for magnetically connecting the main body 701.

[0088] The magnetic member 141 is arranged through the circuit board 400, so that the magnetic member 141 does not occupy too much space, and the structure inside the recess 140 is more compact. The magnetic member 141 is arranged on the first ring part 131, and the first end surface 110 is used as a reference surface, the slope of the inner wall of the first ring part 131 is smaller, and the working surface of the main body 701 is usually parallel to the first end surface 110. Therefore, when the accessory head 800 is mounted on the main body 701, the included angle between the magnetic member 141 arranged on the first ring part 131 and the working surface of the main body 701 is smaller, the magnetic member 141 is more easily connected with the working surface of the main body 701, the magnetic force generated is more uniform, the connection between the working surface of the accessory head 800 and the main body 701 is more compact, the installation position of the accessory head 800 is slightly deviated, the connection between the magnetic member 141 and the main body 701 is not affected, and the normal use of the accessory head 800 is not greatly affected, so that the difficulty of the user in mounting the accessory head 800 on the main body 701 is reduced, and the use experience of the user is improved.

[0089] In order to more stably arrange the magnetic member 141 on the first ring part 131, the limiting groove 131b is arranged on the inner wall of the first ring part 131, which is used for limiting and fixing the magnetic member 141, preventing the magnetic member 141 from deviating under the action of external force, causing damage to the circuit board 400 or affecting the connection effect with the main body 701, and facilitating the installation of the magnetic member 141.

[0090] As shown in Figure 2 , Figure 4 and Figure 6As shown, in some embodiments, a sliding groove 132c is configured on the inner wall of the second ring part 132, and a detection member 132b is arranged in the sliding groove 132c, and the detection member 132b is used to detect whether the accessory head 800 is mounted on the output end of the skin care device; and / or,

[0091] The plurality of electrodes 210 are spaced apart and arranged on the periphery of the light transmission hole 111.

[0092] The detection member 132b is mounted on the second ring part 132 and is isolated from the sealed cavity 600, so as to avoid affecting the detection effect of the components in the sealed cavity 600, and at the same time, the detection member 132b occupies the space in the sealed cavity 600, prevents the detection member 132b from shielding the light emitted by the light-emitting structure in the beauty component 200, and affects the beauty effect. It can be understood that the detection member 132b has many forms, which can be a photoelectric sensor, which can judge whether the accessory head 800 is connected with the skin care device when detecting that the light path changes; it can also be a pressure sensor, which can judge whether the accessory head 800 is connected with the skin care device by detecting whether the pressure applied by the skin care device is applied; it can also be other structures for detecting whether the accessory head is installed in place with the skin care device, and the present application does not limit this.

[0093] The sliding groove 132c is used for placing the detection member 132b, and is usually composed of two spaced-apart plate members and the side wall of the second ring part 132, so that the detection member can be mounted in a suitable position. The sliding groove 132c and the detection member 132b can be fixedly connected by adhesion or interference fit, so that the connection between the sliding groove 132c and the detection member 132b is more stable.

[0094] The skin care assembly further includes a skin care device and an accessory head 800. The specific structure of the accessory head 800 is referred to the above embodiments.
