It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0056] This utility model embodiment provides a beauty device 100, which can be used for skin care on the face and other areas.

[0057] like Figures 1 to 3 As shown, the beauty device 100 includes a main unit 1, a beauty head 2, and a light-emitting module 3. The main unit 1 includes a main housing 11, and the beauty head 2 is disposed on the main housing 11. The beauty head 2 includes multiple electrical contacts 21 and multiple spaced-apart light-emitting holes 221. Each electrical contact 21 includes a connecting end (not shown) and a care end (not shown). The connecting end of each electrical contact 21 corresponds to each light-emitting hole 221, and the care end of each electrical contact 21 protrudes from one end of the beauty head 2 to form a care surface that conforms to the skin. For example, the connecting end of each electrical contact 21 can be inserted into the corresponding light-emitting hole 221, and the care end can protrude from the skin-facing side of the beauty head 2 to form a care surface.

[0058] In this embodiment, the light-emitting module 3 is configured to emit a target beam, which is emitted from the periphery of the corresponding electrical contact 21 through each light-emitting hole 221 to the beauty head 2. Understandably, a hollow light column can be formed around each electrical contact 21. Thus, during the treatment process by the beauty head 2, each electrical contact 21 not only provides microcurrent stimulation to the skin but also simultaneously provides phototherapy to the skin around its periphery. This allows the beauty head 2 to achieve a synergistic effect of microcurrent stimulation and phototherapy, enhancing the skin's ability to absorb skincare products. Furthermore, when the target beam acts on the skin for phototherapy, the skin experiences a warm sensation, which can alleviate the irritation caused by the microcurrent stimulation of the electrical contact 21. Therefore, emitting the target beam from the periphery of the connection end of each electrical contact 21, making the treatment end of each electrical contact 21 equivalent to a light energy column, effectively enhances the user experience of the contact between the electrical contact 21 and the skin, significantly improving the user experience.

[0059] It should be noted that the light-emitting module 3 mentioned here can be a large light-emitting component so that the target beam can be emitted from each light-emitting hole 221. The light-emitting module 3 can also be multiple light-emitting units 31, with each light-emitting hole 221 corresponding to at least one light-emitting unit 31. The target beam emitted by the light-emitting unit 31 corresponding to each light-emitting hole 221 can be emitted from the light-emitting hole 221.

[0060] In summary, compared with existing technologies, this beauty device 100 has at least the following beneficial effects:

[0061] The beauty device 100 has multiple spaced light-emitting holes 221 on the beauty head 2, and the connection ends of each electrical contact 21 are correspondingly set with each light-emitting hole 221. The care end of each electrical contact 21 protrudes from the beauty head 2 to form a care surface that fits the skin. The target beam emitted by the light-emitting module 3 is emitted from the beauty head 2 through each light-emitting hole 221 and exits from the periphery of the connection end of the corresponding electrical contact 21, so as to form a hollow light column around the care end of each electrical contact 21. In this way, the beauty device 100 can not only achieve the synergistic effect of microcurrent stimulation and phototherapy, which is conducive to improving the absorption effect of skin care products, but also make each electrical contact 21 and its surrounding light column form a light energy column with a warm and microcurrent stimulation, which is conducive to improving the experience of each electrical contact 21 touching the skin, thereby improving the user experience.

[0062] To enable those skilled in the art to better understand the present invention, the following will be described in conjunction with the appendix. Figures 1 to 6 The technical solution in Embodiment 1 of this utility model will be clearly and completely described below. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0063] In some embodiments, such as Figures 3 to 5 As shown, to enable the target light beam to exit the beauty head 2 from the periphery of the corresponding electrical contact 21 through the light emission hole 221, the beauty head 2 includes a shell body 22, which serves as a light shield and has multiple spaced light emission holes 221. One end (corresponding to the connection end) of each electrical contact 21 is inserted into the light emission hole 221, and the other end (corresponding to the care end) of each electrical contact 21 protrudes from the shell body 22, together forming a care surface that conforms to the skin. A light emission channel 23 communicating with the outside is formed between the outer wall of each electrical contact 21 and the wall of the corresponding light emission hole 221. Thus, because each light emission channel 23 is located on the periphery of the corresponding electrical contact 21, the target light beam incident on the light emission hole 221 can exit the shell body 22 from the periphery of each electrical contact 21 through the light emission channel 23.

[0064] In some embodiments, the target light beam may include at least two types of light, so that different layers of the skin can be treated separately through the synergistic effect of the two types of light. Optionally, one of the two types of light is yellow light of 590nm±10nm and the other is red light of 630nm±10nm. Yellow light can improve blood circulation in the surface layer, promote cell metabolism, even out skin tone, and soothe the skin. Red light can penetrate deep into the skin to repair and awaken its activity. Thus, through the synergistic effect of yellow and red light, the skin condition can be effectively improved, allowing skincare and / or cosmetic products to adhere better to the skin during makeup application.

[0065] Based on the premise that the target beam can be emitted from the periphery of each electrical contact 21 through the light emission channel 23 and exit the shell body 22, in order to realize that the target beam can finally be emitted from the beauty head 2 and applied to the skin, at least the following specific implementation methods are available:

[0066] In the first embodiment, the beauty head further includes a protective shell, which is disposed on the light-emitting side of the shell body. The protective shell has multiple clearance holes for corresponding electrical contacts to pass through. The protective shell is a light-shielding component, with each clearance hole corresponding to a light-emitting hole, and the size of each clearance hole being greater than or equal to the size of the corresponding light-emitting hole. Each electrical contact is fitted with a light-transmitting sealing ring within its corresponding light-emitting hole. The light-transmitting sealing ring is configured to seal the gap between the light-emitting hole and the electrical contact while allowing the target light beam to pass through. Understandably, the light-transmitting sealing ring is located within the light-emitting channel. On the one hand, the light-transmitting sealing ring seals the light-emitting channel, ensuring that liquids, dust, and other substances do not enter the beauty head through the light-emitting channel, thus improving the safety and lifespan of the beauty device. On the other hand, the target light beam within the light-emitting channel can pass through the light-transmitting sealing ring and the clearance holes through the protective shell to exit the beauty head and reach the skin.

[0067] It should be noted that the light-transmitting sealing rings mentioned here include, but are not limited to, sealing rings made of optically transparent silicone.

[0068] In the second specific implementation, such as Figures 3 to 5 As shown, the beauty head 2 also includes a protective shell 24, which has multiple spaced protrusions 241 protruding towards the shell body 22 (see...). Figure 3 and Figure 4 Each protrusion 241 has a mounting hole 2411 communicating with the outside along its height direction. The protective shell 24 is a light-transmitting component and is disposed on the light-emitting side of the shell body 22. Each protrusion 241 is inserted into the corresponding light-emitting hole 221, and each electrical contact 21 is inserted into the mounting hole 2411 of the corresponding protrusion 241 along its length direction. Understandably, each protrusion 241 corresponds to each light-emitting hole 221, and on the periphery of each electrical contact 21, each protrusion 241 is located in the light-emitting channel 23 between the corresponding light-emitting hole 221 and the corresponding electrical contact 21. Since the protective shell 24 is a light-transmitting component, each protrusion 241 can also transmit light. In this way, the target beam of light incident on each light-emitting hole 221 can be emitted through the protrusion 241 in the corresponding light-emitting channel 23 and emitted from the beauty head 2 to the skin.

[0069] In some embodiments, each electrical contact 21 is cylindrical, and the projection of each electrical contact 21 along its axial direction onto the housing body 22 is located within the light emission hole 221. In this way, on the one hand, it facilitates the emission of the target beam from the light emission channel 23, and on the other hand, the light column formed around each electrical contact 21 can be hollow cylindrical, which is beneficial for concentrating light energy to improve the beauty and skin care effect.

[0070] In some embodiments, such as Figures 2 to 5 As shown, at the positions corresponding to each light-emitting hole 221, the protective shell 24 has a light-emitting cover 242 protruding from the shell body 22. The projection of the light-emitting cover 242 along its height direction on the protective shell 24 covers the light-emitting hole 221. The protective shell 24 also has a clearance hole 2421 on the light-emitting cover 242 for the power supply contact 21 to pass through. Understandably, each light-emitting cover 242 has a cavity (not shown in the figure) formed at the corresponding light-emitting hole 221 position. This cavity communicates with the light-emitting hole 221 of the shell body 22 and the clearance hole 2421 of the protective shell 24. In this way, the target light beam that hits the light-emitting hole 221 can enter the cavity and pass through the light-emitting cover 242 to reach the skin after exiting the shell body 22 through the corresponding light-emitting channel 23 and the protrusion 241. Since the projection of the light-emitting cover 242 on the protective shell 24 covers the light-emitting hole 221, the target light beam can be diffused to a certain extent after entering the cavity. Therefore, it is beneficial to expand the coverage area of ​​the target light beam emitted from the beauty head 2 around each electrical contact 21, thereby improving the care effect of the beauty device 100 and further improving the skin feel of the electrical contact 21.

[0071] In some embodiments, to make the structure of the beauty head 2 more compact and to ensure that the user has a good skin feel, the center lines of each electrical contact 21 and the corresponding light emission hole 221, mounting hole 2411 and clearance hole 2421 are on the same straight line.

[0072] In some embodiments, the structure of the electrical contact 21 has at least the following specific implementations:

[0073] In the first specific implementation, such as Figures 2 to 5 As shown, each electrical contact 21 includes a spring-loaded needle head 211. One end of the spring-loaded needle head 211 (corresponding to the nursing end of the electrical contact 21) protrudes from the light cover 242, and the other end of the spring-loaded needle head 211 (corresponding to the connecting end of the electrical contact 21) is inserted into the mounting hole 2411 of the boss 241. The outer peripheral wall of the spring-loaded needle head 211 and the hole wall of the mounting hole 2411 are sealed by a sealing ring 25. It should be noted that the spring-loaded needle head 211 is elastic. For example, the extension length of the spring-loaded needle head 211 can be adjusted according to the curvature of different parts of the user's face to facilitate the ergonomic design of the nursing surface formed by all the spring-loaded needle heads 211, thereby improving the user's experience.

[0074] In the second specific implementation, such as Figure 6 As shown, each electrical contact 21 includes a connecting rod 212, an elastic element 213, a connector 214, and a contact head 215. One end of the connecting rod 212 (the end facing away from the protective shell 24) is inserted into the mounting hole 2411 of the boss 241, and an axial deformation cavity 2121 is formed at one end of the connecting rod 2122. The elastic element 213 is built into the axial deformation cavity 2121, which allows the connecting rod 212 to move axially. The other end of the connecting rod 212 extends out of the mounting hole 2411 and is covered by the light emitter hood 242. The other end of the connecting rod 212 is connected to one end (e.g., the lower end) of the contact head 215 through the connector 214 (including but not limited to screws or bolts), and the other end of the connecting rod 212 and one end of the contact head 215 are sealed by a seal (not shown in the figure). The other end (e.g., the upper end) of the contact head 215 protrudes from the light emitter hood 242 to allow contact with the skin.

[0075] Of course, in practical applications, the structure of the electrical contact 21 can also be other existing or newly created structures, and no special limitation is made here.

[0076] It should be noted that the sealing element mentioned here can be a sealing ring 25 or a cured sealant, as long as it can prevent substances from entering the inner cavity of the beauty head 2 from the light emission channel 23.

[0077] In some embodiments, to improve the user's skin feel, the ergonomic design of the care surface of the beauty head 2 is implemented, such as... Figure 2As shown, the side of the beauty head 2 facing the skin is divided into at least a first zone 26, a second zone 27, and a third zone 28. The first zone 26 is located in the middle of the beauty head 2, the second zone 27 is located on the outer periphery of the first zone 26, and the third zone 28 is located on the outer periphery of the second zone 27. When each electrical contact 21 includes a spring needle head 211, the spring needle heads 211 set in the first zone 26, the second zone 27 and the third zone 28 are respectively the first spring needle head 2111 spring needle head 211, the second spring needle head 2112 spring needle head 211 and the third spring needle head 2113 spring needle head 211. On the side close to the skin, the height of the end of the first spring needle head 2111 spring needle head 211, the height of the end of the second spring needle head 2112 spring needle head 211 and the height of the end of the third spring needle head 2113 spring needle head 211 gradually increases. In this way, the care surface formed by all electrical contacts 21 can be a concave arc surface that matches the care area, which is conducive to further improving the user's skin feel.

[0078] In some embodiments, the first, second, and third needle tips 2111 and 2121, and 21131, generate different intensities of electromuscular stimulation on the skin. For example, when treating a large area, if the stimulation intensity of the first and third needle tips 2111 and 2121 is relatively low, it is less likely to cause toothache in the user. Furthermore, if the stimulation intensities of the first, second, and third needle tips 2111 and 2121, and 21131, are different, it can create multi-gradient, zoned intensity stimulation, which more easily improves the cosmetic and skincare effects.

[0079] In some embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, the ends of each electrical contact 21 that are in contact with the skin are rounded with a radius of 0.5mm-1.0mm. This effectively reduces the irritation felt by the user when the electrical contact 21 contacts the skin, thus improving the user's experience.

[0080] In some embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, the ends of each electrical contact 21 that contact the skin are rounded at the corners 2114 to form a contact surface 2115 that contacts the skin. Understandably, the middle portion of the end face of each electrical contact 21 that contacts the skin is flat; that is, the electrical contact 21 makes surface contact with the skin. This effectively reduces the user's irritation when the electrical contact 21 contacts the skin, thus improving the user experience.

[0081] In some embodiments, such as Figures 3 to 5As shown, each electrical contact 21 and the light-emitting module 3 is electrically connected to the circuit board 29, and when the beauty head 2 is mounted on the main housing 11, the circuit board 29 is electrically connected to the host 1. In this way, the beauty head 2 can emit a target beam of light through the light-emitting module 3.

[0082] In addition, the light-emitting module 3 includes multiple light-emitting units 31. To make the structure of the beauty head 2 more compact, at least one light-emitting unit 31 is arranged around the periphery of each electrical contact 21 to emit a target beam of light toward the corresponding light-emitting hole 221. For example, as... Figure 5 As shown, each electrical contact 21 is surrounded by four light-emitting units 31. That is, four light-emitting units 31 are arranged circumferentially around each electrical contact 21 on the circuit board 29, and each light-emitting hole 221 corresponds to four light-emitting units 31 emitting target beams toward it.

[0083] In other embodiments, to enable the target light beam to exit the cosmetic head through the light-emitting holes from the periphery of the corresponding electrical contacts, the cosmetic head includes a first housing and a second housing. The first housing is a light-shielding member, and the second housing is a light-transmitting member. The first housing has multiple spaced-apart light-emitting holes configured to allow the target light beam to exit through it. The second housing is located on the light-emitting side of the first housing and has multiple electrical contacts spaced apart thereon; that is, the electrical contacts are directly disposed on the second housing, so that they are disposed together with the second housing on the light-emitting side of the first housing.

[0084] Each electrical contact on the second housing corresponds to one of the light-emitting holes on the first housing, and the size of the end of each electrical contact near the light-emitting hole is smaller than the size of the corresponding light-emitting hole, so as to form a light-emitting channel at the opening of the corresponding light-emitting hole. Understandably, each electrical contact and the opening of the corresponding light-emitting hole have a circumferential gap, which together with the light-emitting hole can form a light-emitting channel. The target beam can directly exit the first housing through the light-emitting hole and pass through the second housing through the circumferential gap, thereby forming a light column surrounding the electrical contact.

[0085] It should be noted that each electrical contact can be smaller than the light-emitting aperture, or the end of each electrical contact near the light-emitting aperture can be smaller than the light-emitting aperture, so as to form a circumferential gap with the light-emitting aperture at the opening of the light-emitting aperture to allow the target beam to pass through the second housing.

[0086] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of the claims of the present invention.
