Description

Technical Field

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

[0002] Existing photon beauty devices all use light waves of specific wavelengths to irradiate the skin to achieve skin care or hair removal effects. In order to ensure the effectiveness of skin care or hair removal, the light-emitting part of the beauty device needs to send a large amount of energy to the skin through strong light in a short period of time. However, since different skin tones have different light absorption rates, the requirements for parameters such as the output power and duration of the beauty device are also different. If the output power is too high, it will cause the user's skin to feel stinging, or even burns. If the output power is too low, it will not be able to achieve the desired skin care or hair removal effect.

[0003] Existing photon beauty devices only offer a few output levels or modes for users to choose from. However, since users are not professionals, their choices are often inaccurate, which affects the effectiveness of the beauty device to some extent. The user experience needs further improvement.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] See Figure 1 This application provides a photon beauty device, comprising a body 1, a first replacement head 2, and a second replacement head 3, wherein the first replacement head 2 and the second replacement head 3 can be selectively mounted on the body 1. The body 1 contains a controller 12 and a light emitter 13. When using the photon beauty device for beauty treatment, the first replacement head 2 is first mounted on the body 1, and the user's skin color is detected by a skin color detector 22 on the first replacement head 2, thereby obtaining a skin color signal, which is transmitted to the controller 12. Then, the first replacement head 2 is replaced with the second replacement head 3, and the controller 12 controls the operating parameters of the light emitter 13 according to the received skin color signal, causing the light emitter 13 to emit beauty light with specific parameters. The beauty light is then irradiated onto the user's skin through the first light outlet 321 on the second replacement head 3, achieving beauty treatment. With this configuration, the photon beauty device can accurately control the operating parameters of the light emitter 13 according to the user's skin color, matching the operating parameters of the light emitter 13 with the skin color, improving the beauty treatment effect, and avoiding stinging sensations and burns, thus enhancing the user experience. Beauty treatments can include skin care or hair removal. The operating parameters of the light emitter 13 include output power, operating time, and wavelength of the beauty light.

[0027] See Figure 2 and Figure 3 The device 1 includes a housing 11, a controller 12, and a light emitter 13. A mounting cavity 114 is formed inside the housing 11, and a second light outlet 1131 is provided on the housing 11, connecting the mounting cavity 114 and the outer surface of the housing 11. The controller 12 and the light emitter 13 are mounted within the mounting cavity 114, and the beauty light emitted by the light emitter 13 can shine onto the user's skin through the second light outlet 1131.

[0028] The outer casing 11 has a connected handheld portion 115 and a working portion 116. The working portion 116 is located at one end of the handheld portion 115, and the handheld portion 115 and the working portion 116 form an approximately T-shaped structure. The dimensions of the handheld portion 115 are designed for comfortable gripping by the user, allowing for easy holding and beauty treatments. The controller 12 and the emitter 13 are both located inside the working portion 116, and the dimensions of the working portion 116 can be designed according to the installation space required for the controller 12 and the emitter 13. This design ensures that even when the installation space required for the controller 12 and the emitter 13 is large, the dimensions of the handheld portion 115 will not be affected, thus guaranteeing user comfort when holding the photon beauty device. In other embodiments, when the installation space required for the controller 12 and the emitter 13 is small, the overall shape of the outer casing 11 can also be designed to be easily gripped by the user.

[0029] The second light outlet 1131 is provided at the front end of the working part 116, so that the beauty light emitted by the light emitter 13 can be emitted from the front end of the working part 116. The front end of the working part 116 is provided with a mounting position 1132 for mounting the first replacement head 2 and the second replacement head 3 at the location corresponding to the second light outlet 1131.

[0030] In one embodiment, the outer casing 11 includes a first half-shell 111, a second half-shell 112, and a front casing 113. The first half-shell 111 and the second half-shell 112 have identical structures and are mirror images of each other. The first half-shell 111 and the second half-shell 112 are fixedly connected, and together they form a mounting cavity 114 with an opening at one end. The front casing 113 is fixedly connected to the first half-shell 111 and the second half-shell 112 and is located at the opening of the mounting cavity 114. A mounting position 1132 and a second light outlet 1131 are disposed on the front casing 113. The first half-shell 111 and the second half-shell 112 can be connected by screws or by snap-fit ​​connections, and the front casing 113 can also be connected to the first half-shell 111 and the second half-shell 112 by screws or by snap-fit ​​connections. The outer shell 11 is divided into a first half shell 111, a second half shell 112 and a front shell 113. This makes it easier for the first half shell 111 and the second half shell 112 to be demolded during injection molding, reducing manufacturing difficulty, and ensuring the positional accuracy of the mounting position 1132 for connection with the first and second replacement heads 3.

[0031] In other embodiments, the housing 11 includes a first half-shell 111 and a second half-shell 112. The first half-shell 111 and the second half-shell 112 have identical structures and are mirror images of each other. The first half-shell 111 and the second half-shell 112 are fixedly connected, and their front ends form mounting positions 1132 for mounting the first replacement head 2 and the second replacement head 3. The second light outlet 1131 is located at the mounting position 1132. Dividing the housing 11 into the first half-shell 111 and the second half-shell 112 facilitates the draft molding process of the first half-shell 111 and the second half-shell 112 during injection molding, reducing manufacturing difficulty.

[0032] Both the controller 12 and the emitter 13 are fixedly connected to the outer casing 11. The emitter 13 is positioned near the second light outlet 1131 on the outer casing 11, facilitating the emission of the cosmetic light emitted by the emitter 13. The controller 12 is positioned on the side of the emitter 13 facing away from the second light outlet 1131. This arrangement makes the placement of the controller 12 and the emitter 13 on the outer casing 11 more rational.

[0033] The controller 12 is a processor with an internal control program, such as a microcontroller.

[0034] The light emitted by the light emitter 13 includes, but is not limited to, one or more of the following: red light in the 630-640nm band, blue light in the 410-450nm band, green light in the 530-550nm band, yellow light in the 580-590nm band, and laser light in the 694-1200nm band.

[0035] In one embodiment, the device body 1 further includes a rechargeable battery 14, which is electrically connected to the controller 12, enabling the rechargeable battery 14 to provide power for the operation of the controller 12 and the light emitter 13. The rechargeable battery 14 is disposed inside the handheld part 115, making full use of the space inside the handheld part 115 and resulting in a more compact overall structure of the photon beauty device.

[0036] In one embodiment, the body 1 further includes a display screen 15, which is disposed on the working part 116 and electrically connected to the controller 12. The display screen 15 is used to display the operating parameters of the emitter 13 and the user's skin color detected by the skin color detector 22. In other embodiments, the display screen 15 may also be used only to display the operating parameters of the emitter 13 or the user's skin color detected by the skin color detector 22. A mounting opening may be provided on one of the first half-shell 111 or the second half-shell 112, the shape of the display screen 15 is adapted to the mounting opening, and the display screen 15 is mounted at the mounting opening.

[0037] A first electrical connector 16 is provided at the mounting position 1132 of the housing 11. The first electrical connector 16 is located on one side of the second light outlet 1131 and is electrically connected to the controller 12. The first electrical connector 16 is used for electrical connection with the first replacement head 2. In one embodiment, the first electrical connector 16 is a socket structure or a contact structure and is provided on the front cover 113.

[0038] See Figure 4 and Figure 5 The first replacement head 2 includes a first replacement head housing 21 and a skin tone detector 22. The first replacement head housing 21 is detachably connected to the mounting position 1132 of the main housing 11. The first replacement head housing 21 has a clearance hole 2111 communicating with its outer surface. The skin tone detector 22 is disposed inside the first replacement head housing 21, and the detection light emitted by the skin tone detector 22 can pass through the clearance hole 2111 to illuminate the user's skin. The detection light reflected from the user's skin surface can also pass through the clearance hole 2111 to reach the skin tone detector 22. When the first replacement head 2 is connected to the mounting position 1132, the skin tone detector 22 is electrically connected to the first electrical connector 16, realizing the electrical connection between the skin tone detector 22 and the controller 12.

[0039] The first replacement head housing 21 includes a front replacement head housing 211 and a rear replacement head housing 212. The front replacement head housing 211 has a cavity with an opening at one end. The rear replacement head housing 212 is connected to the cavity of the front replacement head housing 211 and seals the opening of the cavity, thus forming a mounting cavity 213 between the rear replacement head housing 212 and the front replacement head housing 211 for mounting the skin color detector 22. The front replacement head housing 211 has a first connecting portion 2112 formed at the edge of the cavity opening for connection with the mounting position 1132. The connection between the first replacement head housing 21 and the mounting position 1132 is achieved through the cooperation of the first connecting portion 2112 with the mounting position 1132.

[0040] In one embodiment, the outer surface of the housing 11 protrudes to form a mounting position 1132. The first connecting part 2112 of the replacement head front shell 211 is fitted onto the circumferential outer surface of the mounting position 1132 and engages with the outer wall surface of the mounting position 1132, thereby realizing a detachable connection between the first replacement head housing 21 and the mounting position 1132.

[0041] In one embodiment, the surface of the housing 11 is recessed to form a mounting position 1132. The first connecting part 2112 of the replacement head front shell 211 is inserted into the mounting position 1132 and engages with the inner side wall of the mounting position 1132, thereby realizing a detachable connection between the first replacement head housing 21 and the mounting position 1132.

[0042] In one embodiment, the replacement head front cover 211 and the mounting position 1132 can be connected by an interference fit to achieve a snap-fit ​​between the replacement head front cover 211 and the mounting position 1132 of the housing 11. Alternatively, a first latch is provided on the mounting position 1132, and a second latch is provided on the replacement head front cover 211, with the second latch engaging with the first latch to achieve a snap-fit ​​between the replacement head front cover 211 and the mounting position 1132 of the housing 11.

[0043] In other embodiments, a first magnetic attractor is provided on the mounting position 1132, and a second magnetic attractor is provided on the front shell 211 or the rear shell 212 of the replacement head. The second magnetic attractor can magnetically attract the first magnetic attractor, thereby realizing a detachable connection between the mounting position 1132 of the first replacement head shell 21 and the body shell 11. In this embodiment, one of the first magnetic attractor and the second magnetic attractor is a magnet, and the other is an iron sheet or a magnet.

[0044] The skin color detector 22 is fixedly connected to the rear shell 212 of the replacement head, and the clearance hole 2111 is opened on the front shell 211 of the replacement head and is located on the side opposite to the skin color detector 22 and opposite to the rear shell 212 of the replacement head.

[0045] The skin color detector 22 includes a substrate, a light-emitting end, and a receiving end. The substrate is fixed on a mounting bracket 113, and the light-emitting end and the receiving end are spaced apart and positioned on the same side of the substrate. The substrate can be a PCB board. The light-emitting end can emit detection light with multiple wavelengths, such as white light. The receiving end can receive the detection light reflected from the skin surface and entering the receiving end. Since different skin colors have different absorption rates for different wavelengths of detection light, the wavelengths of the detection light reflected from the skin surface to the receiving end are also different when the skin color is different. The skin color detector 22 determines the skin color based on the light signal formed by the detection light received by the receiving end, and thus obtains a skin color signal.

[0046] Based on skin color, skin tones are categorized into several types from light to dark. The skin tone detector 22 determines the skin color type by receiving the light reflected from the skin surface and entering the receiver. Different skin types react differently to light, therefore, appropriate wavelengths and energy settings need to be selected according to the skin type. Using different wavelengths of light for different skin tones can improve the effectiveness of beauty treatments. For example, skin color types are specifically classified as Fitzpatrick Scale Types I-VI, with six different skin tone categories: Type I: Fair skin, always gets sunburned, never tans. Type II: Light skin, very easily sunburned, rarely tans. Type III: Medium skin tone, sometimes sunburned, tans slowly. Type IV: Olive skin tone, rarely sunburned, tans quickly. Type V: Dark brown skin tone, rarely sunburned, tans quickly. Type VI: Black skin tone, never sunburned, always black.

[0047] For example, a 755nm laser is suitable for people with lighter skin tones, an 808nm laser is suitable for people with lighter to medium skin tones, and a 1064nm laser is suitable for people with darker skin tones. Different wavelengths of light are suitable for different skin tones, avoiding laser damage to the skin during the procedure.

[0048] Since the skin color detector 22 is electrically connected to the controller 12 when the first replacement head 2 is connected to the mounting position 1132, the skin color signal obtained by the skin color detector 22 can be transmitted to the controller 12. The controller 12 can control the operating parameters of the light emitter 13 according to the skin color signal transmitted by the skin color detector 22, so that the light emitter 13 emits beauty light with specific parameters to the user's skin, improving the beauty or hair removal effect and enhancing the user's experience.

[0049] The first replacement head 2 also includes a fixing bracket 23 and a skin color detection lens 24. The fixing bracket 23 is fixed within the mounting cavity 213 of the first replacement head housing 21. The fixing bracket 23 has a mounting hole 231, which is aligned with the clearance hole 2111, ensuring that both are within the optical path of the skin color detector 22. The skin color detection lens 24 is embedded in the mounting hole 231, thus fixing the skin color detection lens 24 to the fixing bracket 23 and placing it within the optical path of the skin color detector 22. In other embodiments, the skin color detection lens 24 can also be fixed to the fixing bracket 23 using clips or screws. In other embodiments, the skin color detection lens 24 can also be directly fixed to the front housing 211 or the rear housing 212 of the replacement head.

[0050] The skin tone detection lens 24 is an optical lens with collimation and / or focusing functions. When the first replacement head 2 is used to detect the user's skin tone, the detection light emitted from the light-emitting end of the skin tone detector 22 is collimated or focused by the skin tone detection lens 24 before illuminating the skin, resulting in more concentrated light on the skin surface. Furthermore, the detection light reflected from the skin surface onto the skin tone detection lens 24 is collimated or focused by the lens 24 before entering the receiving end of the skin tone detector 22. By incorporating the skin tone detection lens 24 into the optical path of the skin tone detector 22, the accuracy of the skin tone detection is improved.

[0051] For example, the optical lens has a collimation function. The detection light emitted by the skin tone detector 22 is divergent, and after being collimated by the skin tone detection lens 24, it becomes parallel light, allowing more detection light to reach the user's skin. For example, the optical lens has a focusing function. The detection light emitted by the skin tone detector 22 is parallel light, and after being focused by the skin tone detection lens 24, the detection light reaching the user's skin is more concentrated. For example, the optical lens has both focusing and collimation functions. The detection light emitted by the skin tone detector 22 is divergent, and when the detection light enters the skin tone detection lens 24, it is collimated into parallel light; when the parallel light exits the skin tone detection lens 24, it is focused.

[0052] Preferably, when the first replacement head 2 is used to detect the user's skin color, the end face of the skin color detection lens 24 away from the skin color detector 22 contacts the user's skin, so that more detection light is reflected and enters the receiving end of the skin color detector 22, thereby improving the accuracy of the skin color detector 22 in detecting the user's skin color.

[0053] In one embodiment, one end of the skin tone detection lens 24 passes through the clearance hole 2111, and the end face of the skin tone detection lens 24 facing away from the skin tone detector 22 is flush with the outer surface of the first replacement head housing 21. This arrangement ensures that when the first replacement head 2 contacts the user's skin surface, both the end face of the skin tone detection lens 24 away from the skin tone detector 22 and the outer surface of the first replacement head housing 21 simultaneously contact the user's skin surface, increasing the contact area and improving user comfort.

[0054] The first replacement head 2 also includes a second electrical connector 25, which is fixed to the rear shell 212 of the replacement head and is electrically connected to the skin color detector 22. When the first replacement head 2 is connected to the mounting position 1132, the second electrical connector 25 is electrically connected to the first electrical connector 16, thereby realizing the electrical connection between the skin color detector 22 and the controller 12.

[0055] exist Figure 5 In the illustrated embodiment, the second electrical connector 25 is a pin structure. One end of the pin structure is located within the mounting cavity 213 and is electrically connected to the skin color detector 22. The other end penetrates through the replacement head rear housing 212 and extends to the outside of the replacement head rear housing 212. In this embodiment, the first electrical connector 16 is a socket structure. When the first replacement head 2 is connected to the mounting position 1132, the pin structure is inserted into the socket structure on the housing 11, realizing the electrical connection between the skin color detector 22 and the controller 12.

[0056] In other embodiments, the first electrical connector 16 is a contact structure, which is located at the mounting position 1132 and electrically connected to the controller 12. The second electrical connector 25 is a conductive pin structure, one end of which is located within the mounting cavity 213 and electrically connected to the skin color detector 22, and the other end penetrates through the replacement head rear shell 212 and extends to the outside of the replacement head rear shell 212. When the first replacement head 2 is connected to the mounting position 1132, the conductive pin structure abuts against the contact structure, realizing the electrical connection between the skin color detector 22 and the controller 12.

[0057] The first replacement head 2 also includes a first signal recognition chip, which is installed inside the housing 21 of the first replacement head, specifically fixed to the front housing 211, the rear housing 212, or the mounting bracket 23. The first signal recognition chip is electrically connected to the second electrical connector 25. When the first replacement head 2 is connected in the mounting position, the controller 12 can recognize the replacement head recognition signal stored in the first signal recognition chip. Before the controller 12 controls the skin color detector 22 to detect the user's skin color, it first recognizes the replacement head recognition signal stored in the first signal recognition chip. If the recognized replacement head recognition signal is the recognition signal of the first replacement head, the controller controls the skin color detector 22 to detect the user's skin color; if the recognized replacement head recognition signal is not the recognition signal of the first replacement head, a prompt can be displayed on the screen to prevent the user from using the skin color detection function when the second replacement head 3 is installed on the device 1.

[0058] See Figure 1 The detachable connection between the second replacement head 3 and the mounting position 1132 of the housing 11 is the same as the detachable connection between the first replacement head housing 21 and the mounting position 1132 of the housing 11, and will not be described again here.

[0059] In one embodiment, multiple second replacement heads 3 are configured, each second replacement head 3 having a first light-emitting port 321, through which the cosmetic light emitted by the light emitter 13 can pass and be emitted onto the user's skin. The size or shape of the first light-emitting port 321 of the multiple second replacement heads 3 are different. The user selects a second replacement head 3 with a matching first light-emitting port 321 according to the area and shape of the desired cosmetic treatment. For example, when the user needs to perform phototherapy on small acne areas, a second replacement head 3 with a smaller first light-emitting port 321 is selected; when the user needs to perform phototherapy on larger dark spots, a second replacement head 3 with a larger first light-emitting port 321 is selected.

[0060] See Figure 6In one embodiment, the second replacement head 3 includes a second replacement head housing 31 and a light guide hood 32. The second replacement head housing 31 is provided with a second connecting portion 311, which is detachably connected to the mounting position 1132 of the body housing 11. The connection method between the second connecting portion 311 and the mounting position 1132 is the same as the connection method between the first connecting portion 2112 and the mounting position 1132. The second replacement head housing 31 is provided with a mounting through hole. The light guide hood 32 is a hollow annular structure with openings at both ends, and the light guide hood 32 is fixed in the mounting through hole. The interior of the light guide hood 32 forms a first light outlet 321. By setting the light guide hood 32, the beauty beam emitted by the light emitter 13 is more concentrated under the reflection of the light guide hood 32.

[0061] The second replacement head 3 also includes a second signal recognition chip and a third electrical connector. The second signal recognition chip is disposed inside the housing 31 of the second replacement head, and the third electrical connector is fixedly connected to the housing 31 of the second replacement head and connected to the second signal recognition chip. The third electrical connector is used for electrical connection with the first electrical connector 16. When the second replacement head 3 is connected to the mounting position 1132, the controller 12 can recognize the replacement head recognition signal stored in the second signal recognition chip. Before the controller 12 controls the emitter 13 to emit beauty light, it first recognizes the replacement head recognition signal stored in the second signal recognition chip. If the recognized replacement head recognition signal is the recognition signal of the second replacement head, the controller controls the emitter 13 to emit beauty light; if the recognized replacement head recognition signal is not the recognition signal of the second replacement head, a prompt can be displayed on the screen to prevent the user from using the beauty care function when the first replacement head 2 is installed on the body 1.

[0062] The structure of the third electrical connector is the same as that of the second electrical connector 25. The electrical connection method between the third electrical connector and the first electrical connector 16 is also the same as that between the second electrical connector 25 and the first electrical connector 16, and will not be described again here.

[0063] The photon beauty device of this application includes a body 1 and a first replacement head 2 and a second replacement head 3 detachably connected to the body 1. The body 1 is equipped with a controller 12 and a light emitter 13. When using the photon beauty device for beauty treatments or hair removal, the first replacement head 2 is first mounted on the body 1, and the skin color detector 22 on the first replacement head 2 detects the user's skin color, thus obtaining a skin color signal. The skin color detector 22 transmits the skin color signal to the controller 12. Then, the first replacement head 2 is replaced with the second replacement head 3. The controller 12 controls the operating parameters of the light emitter 13 according to the received skin color signal, so that the light emitter 13 emits beauty light with specific parameters, which is then irradiated onto the user's skin through the first light outlet 321 on the second replacement head 3. With this configuration, the photon beauty device can accurately control the operating parameters of the light emitter 13 according to the user's skin color, matching the operating parameters of the light emitter 13 with the skin color, improving the beauty treatment effect, and avoiding stinging sensations and burns, thus enhancing the user experience.
