Description

[0002] Nowadays, portable skin treatment devices have been popularized into people's daily life. These devices use light to act on the skin, which can achieve the functions of hair removal and / or skin rejuvenation, etc. For example, a portable skin treatment device can remove hair on the body by emitting light of a specific wavelength, while a portable skin rejuvenation device can change the skin state by emitting light of a specific wavelength to achieve the effect of skin rejuvenation, etc.

[0003] In these skin treatment devices, sometimes an additional accessory head needs to be connected to adjust the size of the light output of the skin treatment device or to convert and adjust the emitted light to meet the hair removal needs of different parts. Some skin treatment devices are equipped with multiple accessory heads of different types. When the skin treatment device is equipped with an accessory head of a different type, the skin treatment device needs to be adjusted to the corresponding working mode to achieve better care effect. The existing skin treatment devices usually set sensors on the care end of the skin treatment device to identify the type of the accessory head installed on the hair removal device by sensing the corresponding sensing piece on the accessory head. However, the above identification scheme needs to set additional sensors on the care end, and the use of sensors increases the cost, and the installation of sensors requires slotting or hole opening on the care end, which reduces the appearance of the care end of the skin treatment device.

[0034] Portable skin treatment devices (hair removal devices, skin rejuvenation devices, etc.) have been popularized into people's daily life, and these skin treatment devices use light to act on the skin to achieve hair removal and / or skin rejuvenation functions. In these skin treatment devices, sometimes an additional accessory head needs to be connected to adjust the size of the light emitted by the skin treatment device or to convert and adjust the emitted light to meet the hair removal needs of different parts. Some skin treatment devices are equipped with multiple accessory heads of different types, and when the skin treatment device is assembled with an accessory head of a different type, the skin treatment device needs to be adjusted to the corresponding working mode to make the skin treatment device achieve better care effect.

[0035] The existing skin treatment device usually sets a sensor on the treatment end of the skin treatment device, and identifies the type of the accessory head installed on the epilator through the sensor sensing the corresponding sensing piece on the accessory head. However, the above identification scheme needs to additionally set a sensor on the treatment end, and the use of the sensor increases the cost, and the installation of the sensor needs to groove or hole on the treatment end, which reduces the appearance of the treatment end of the skin treatment device.

[0036] To solve the above problems, the applicant of the present application proposes a new skin treatment device, which does not need to additionally set a sensor on the treatment end to identify the type of the accessory head, reduces the cost of the skin treatment device, avoids grooving or hole on the treatment end, and improves the appearance of the skin treatment device.

[0037] Reference Figures 1 to 3 In the embodiment, the skin treatment device includes a housing 10, a color recognition assembly 40, a plurality of accessory heads 20 and a controller 30, and the embodiment Figure 1 In the embodiment, the skin treatment device includes a housing 10, a color recognition assembly 40, a plurality of accessory heads 20 and a controller 30, and the embodiment

[0038] The housing 10 includes a treatment end 11, the treatment end 11 has an action surface 111, the action surface 111 is provided with an energy output window 1111 and a light transmission window 1112; the color recognition assembly 40 is arranged in the housing 10, and is used for detecting light entering through the light transmission window 1112. When the action surface 111 directly adheres to the skin, the color recognition assembly 40 emits detection light from the light transmission window 1112, the detection light is reflected after irradiating on the skin, and the color recognition assembly 40 determines the skin color of the current action area according to the color parameter of the skin reflection light entering through the light transmission window 1112.

[0039] Multiple accessory heads 20 can be selectively installed on the treatment end 11. Each accessory head 20 has a feature portion 22 corresponding to the position of the light-transmitting window 1112, and an accessory window 21 corresponding to the energy output window 1111. When the skin treatment device is equipped with the accessory head 20, the skin treatment device outputs energy to the skin through the accessory window 21. The feature portions 22 of each accessory head 20 are different, each used to form light of different colors or combinations of colors directed towards the light-transmitting window 1112. For example, the feature portion 22 reflects light to form light of the corresponding color or combination of colors directed towards the light-transmitting window 1112; or, for example, light reflected from the skin passes through the feature portion 22 to form light of the corresponding color or combination of colors directed towards the light-transmitting window 1112. In this embodiment, a color combination refers to a combination of multiple colors, such as red-green, red-blue, yellow-green, yellow-blue, red-yellow-green, red-yellow-blue, etc.

[0040] Among them, the multiple auxiliary heads 20 include at least two kinds of auxiliary heads 20, and each auxiliary head 20 includes one or more.

[0041] The controller 30 of the skin treatment device is electrically connected to the color recognition component 40, and determines the skin color and / or the type of the attached accessory head 20 based on the signal fed back by the color recognition component 40. When the accessory head 20 is not installed on the treatment end 11 of the housing 10, when the application surface 111 is in contact with the skin, the color recognition component 40 emits detection light from the light transmission window 1112 and shines it onto the skin. The skin reflects the detection light back to the corresponding reflected light entering through the light transmission window 1112. The color recognition component 40 detects and identifies the skin reflected light entering through the light transmission window 1112 to obtain the skin color. When the accessory head 20 is installed on the treatment end 11 of the housing 10, the feature portion 22 of the accessory head 20 will generate light of the corresponding color or a combination of colors that enters through the light transmission window 1112. The color recognition component 40 detects and identifies the light generated by the feature portion 22 to obtain the corresponding color feature information. Based on this color feature information, the type of accessory head 20 can be determined, i.e., which accessory head 20 it is.

[0042] In this embodiment of the skin treatment device, each accessory head 20 is provided with a feature portion 22 corresponding to the light-transmitting window 1112, and the feature portions 22 of each accessory head 20 are different, so as to form light of different colors or different color combinations that are directed toward the light-transmitting window 1112. Thus, when the treatment end 11 is equipped with an accessory head 20, the feature portion 22 of the accessory head 20 will form light of the corresponding color or color combination that is directed toward the light-transmitting window 1112. The color recognition component 40 can identify the corresponding color or color combination based on the light entering from the light-transmitting window 1112 and feed back a signal corresponding to the identified color or color combination to the controller 30. The controller 30 can then determine the type of accessory head 20 equipped based on the signal fed back by the color recognition component 40. When the treatment end 11 is not equipped with an accessory head 20, the light entering the light-transmitting window 1112 is skin-colored reflected light, and the color recognition component 40 identifies the skin color based on the light entering from the light-transmitting window 1112. Compared to existing skin treatment devices, this embodiment utilizes the existing color recognition component 40 of the skin treatment device to complete the type recognition of the auxiliary head 20, eliminating the need for additional sensors and effectively reducing the cost of the skin treatment device. Furthermore, the care end 11 of the skin treatment device no longer needs to be slotted or drilled to install sensors, making the care end 11 of the skin treatment device more aesthetically pleasing.

[0043] Reference Figure 4In some embodiments, the skin treatment device further includes a first accessory head 201, which has a colorless transparent portion 221 corresponding to the position of the light-transmitting window 1112 and an accessory window 21 corresponding to the energy output window 1111. When the first accessory head 201 is mounted on the treatment end 11, although the colorless transparent portion 221 of the first accessory head 201 has no color, when the skin treatment device is in use, the colorless transparent portion 221 will produce a small amount of reflection of the detection light emitted from the light-transmitting window 1112 by the color recognition component 40. The light reflected by the colorless transparent portion 221 enters through the light-transmitting window 1112, and the color recognition component 40 can identify the difference between the light received when the accessory head 201 is not installed by detecting and identifying the light entering from the light-transmitting window 1112, thereby determining that the treatment end 11 is equipped with the first accessory head 201 with the colorless transparent portion 221. Of course, most of the detection light from the color recognition component 40 will pass through the colorless transparent portion 221 and illuminate the skin, causing skin reflection light to pass through the colorless transparent portion 221 and return to the light transmission window 1112. Since the colorless transparent portion 221 has very little influence on the detection light and skin reflection light, the color recognition component 40 can still correctly identify the skin color based on the skin reflection light. In addition, when it is determined that the first auxiliary head 201 is installed, the reflected light received by the color recognition component 40 can be compensated accordingly (for example, the controller 30 sets a compensation coefficient corresponding to the first auxiliary head 201) to make the color recognition component 40 maintain more accurate skin color recognition.

[0044] Reference Figure 5 In some embodiments, the various accessory heads 20 include a second accessory head 202. The characteristic portion 22 of the second accessory head 202 is a colored reflective portion 222, which is a reflective portion having color. In this embodiment, when the second accessory head 202 is installed on the nursing end 11, the colored reflective portion 222 of the second accessory head 202 reflects the detection light emitted by the color recognition component 40 to form colored light corresponding to the color of the colored reflective portion 222, which is directed towards the light-transmitting window 1112. The color recognition component 40 receives the colored light reflected by the colored reflective portion 222 from the light-transmitting window 1112. By detecting and identifying the color of the received colored light, the color recognition component 40 determines that the accessory head 20 installed on the nursing end 11 is the second accessory head 202 based on the correspondence between the color and the accessory head 20. The number of second accessory heads 202 can be one or more.

[0045] In some embodiments, there are multiple second auxiliary heads 202. The colored reflective portions 222 of the second auxiliary heads 202 may be of a single color, and the colors of the colored reflective portions 222 of each second auxiliary head 202 may be different. For example, if there are three second auxiliary heads 202, the colors of the colored reflective portions 222 of the three second auxiliary heads 202 may be red, green, and yellow, respectively. Alternatively, the colored reflective portions 222 may have multiple colors, and the color combinations of the colored reflective portions 222 of the multiple second auxiliary heads 202 may be different. For example, if there are three second auxiliary heads 202, the color combinations of the colored reflective portions 222 of the three second auxiliary heads 202 may be red-yellow, red-green, and yellow-green, respectively.

[0046] In this embodiment of the skin treatment device, when different second auxiliary heads 202 are installed on the treatment end 11, the color recognition component 40 detects and identifies the color or color combination of the received colored light (i.e., the reflected light from the colored reflective part 222 of the second auxiliary head 202), and determines which model of the auxiliary head 20 installed on the treatment end 11 is based on the correspondence between the color or color component and the auxiliary head 20. Since the color or color combination of the colored reflective part 222 of each second auxiliary head 202 is different, that is, each second auxiliary head 202 has a unique corresponding color or color combination, each second auxiliary head 202 can be a different model, such as different sizes of auxiliary windows 21, that is, the size of the auxiliary windows 21 of each second auxiliary head 202 is different; in this way, the skin treatment device can be equipped with more types and models of auxiliary heads 20.

[0047] In some embodiments, the colored reflective portion 222 may be a reflective coating disposed on the inner side of the second accessory head 202 (i.e., the side facing the light-transmitting window 1112). The reflective coatings of each second accessory head 202 may have different colors or color combinations. The reflective coating may be a coating of the same color, a coating of multiple colors mixed together, or a reflective coating divided into multiple areas of different colors.

[0048] In some embodiments, the colored reflective portion 222 may also be a reflective film attached to the inner surface of the second accessory head 202. The reflective film of each second accessory head 202 has a different color or color combination. The reflective film may be a monochrome reflective film, a multi-colored reflective film, or the reflective film may be divided into multiple areas of different colors.

[0049] Of course, in some other embodiments, the colored reflective portion 222 may also be other colored reflective structures disposed inside the second auxiliary head 202.

[0050] In some embodiments, the plurality of accessory heads 20 includes a second accessory head 202. The feature portion 22 of the second accessory head 202 is a colored reflective portion 222. There are multiple second accessory heads 202, and the reflectivity of the colored reflective portions 222 of the multiple second accessory heads 202 is different. For example, there are four second accessory heads 202, and the reflectivity of the colored reflective portions 222 of the four second accessory heads 202 are 30%, 50%, 70%, and 85%, respectively. The colored reflective portions 222 of each second accessory head 202 may be made of different materials to achieve different reflectivity, or other methods may be used to achieve different reflectivity. In this embodiment, the colored reflective portions 222 of each second accessory head 202 may be the same color, or they may be different colors or combinations of colors.

[0051] In this embodiment of the skin treatment device, when the second auxiliary head 202 is installed on the nursing end 11, the color recognition component 40 receives the colored light reflected by the colored reflective part 222 of the second auxiliary head 202. By detecting and recognizing the received colored light, the color of the colored light is obtained. Based on the correspondence between the color and the type of auxiliary head 20, it is determined that the installed auxiliary head 20 is the second auxiliary head 202. If multiple second auxiliary heads 202 have colored reflective portions 222 of the same color, and since the reflectivity of the colored reflective portions 222 of the multiple second auxiliary heads 202 is different, the intensity of the colored light reflected by the colored reflective portions 222 of the second auxiliary heads 202 will be different when different second auxiliary heads 202 are installed on the nursing end 11. The color recognition component 40 can further determine which second auxiliary head 202 is installed on the nursing end 11 by analyzing the intensity of the received colored light and according to the correspondence between the colored reflective portions 222 and the reflectivity of each second auxiliary head 202.

[0052] Reference Figure 6 and Figure 7In some embodiments, the plurality of auxiliary heads 20 include a second auxiliary head 202. The feature 22 of the second auxiliary head 202 is a colored reflective portion 222. There are multiple second auxiliary heads 202, and the colored reflective portions 222 of the multiple second auxiliary heads 202 have different structures facing the light-transmitting window 1112. Since the side of the colored reflective portion 222 facing the light-transmitting window 1112 (hereinafter referred to as the reflective surface for ease of description) is a reflective surface that reflects the detection light emitted by the color recognition component 40, the structure of the reflective surface affects the direction of the reflected light, and thus affects the amount of light entering the light-transmitting window 1112. The reflective surface of the second auxiliary head 202 may include smooth areas and rough areas, and the area of ​​the smooth areas in the reflective surfaces of each second auxiliary head 202 is different, so the amount of light reflected from the reflective surfaces of each second auxiliary head 202 to the light-transmitting window 1112 is different. Of course, the reflective surfaces of each second auxiliary head 202 can also be rough surfaces with different degrees of roughness, or surfaces with other structural shapes. In this embodiment, the colored reflective portions 222 of each second auxiliary head 202 can be the same color, or they can be different colors or combinations of colors.

[0053] In this embodiment of the skin treatment device, when the second auxiliary head 202 is installed on the nursing end 11, the color recognition component 40 receives colored light reflected from the colored reflective part 222 of the second auxiliary head 202. By detecting and recognizing the received colored light, the color of the colored light is obtained. Based on the correspondence between the color and the type of auxiliary head 20, the installed auxiliary head 20 is determined to be the second auxiliary head 202. If multiple second auxiliary heads 202 have the same colored reflective part 222, since the reflective surfaces of the multiple second auxiliary heads 202 have different structures, the amount of colored light received by the color recognition component 40 when different second auxiliary heads 202 are installed on the nursing end 11 will vary, that is, the intensity of the received colored light will be different. The color recognition component 40 can further determine which specific second auxiliary head 202 is installed on the nursing end 11 by analyzing the intensity of the received colored light.

[0054] In some embodiments, the multiple accessory heads 20 include a third accessory head 203. The feature portion 22 of the third accessory head 203 is a colored light-transmitting portion 223, that is, a colored light-transmitting portion. The colored light-transmitting portion 223 can be an inorganic material such as quartz or a light-transmitting organic polymer material. In this embodiment, when the third accessory head 203 is installed on the nursing end 11, the detection light of the color recognition component 40 shines on the skin through the colored light-transmitting portion 223, causing the skin to reflect light, which then shines back through the colored light-transmitting portion 223 to the light-transmitting window 1112. The light that shines back through the colored light-transmitting portion 223 to the light-transmitting window 1112 is colored light with the color of the colored light-transmitting portion 223. Thus, the color recognition component 40 receives the colored light reflected back from the colored light-transmitting portion 223 from the light-transmitting window 1112. By detecting and recognizing the color of the received colored light, and based on the correspondence between the color and the accessory head 20, it is determined that the accessory head 20 installed on the nursing end 11 is the third accessory head 203. The number of third subsidiary heads 203 is one or more.

[0055] In addition, when it is determined that the third auxiliary head 203 is installed, the colored light received by the color recognition component 40 can be compensated accordingly (for example, the controller 30 sets a compensation coefficient corresponding to the third auxiliary head 203) so that the color recognition component 40 can normally recognize the skin color according to the received colored light.

[0056] In some embodiments, there are multiple third auxiliary heads 203. The colored light-transmitting portions 223 of the third auxiliary heads 203 may be of a single color, and the colors of the colored light-transmitting portions 223 of each third auxiliary head 203 may be different. For example, if there are three third auxiliary heads 203, the colors of the colored light-transmitting portions 223 of the three third auxiliary heads 203 may be orange, blue, and purple, respectively. Alternatively, the colored light-transmitting portions 223 may be of multiple colors, and the color combinations of the colored light-transmitting portions 223 of the multiple third auxiliary heads 203 may be different. For example, if there are three third auxiliary heads 203, the color combinations of the colored light-transmitting portions 223 of the three third auxiliary heads 203 may be orange-yellow, blue-red, and purple-green, respectively.

[0057] In this embodiment of the skin treatment device, when different third auxiliary heads 203 are installed on the treatment end 11, the color recognition component 40 detects and identifies the color or color combination of the received colored light (i.e., the reflected light from the colored light-transmitting part 223 of the third auxiliary head 203), and determines which model of the third auxiliary head 203 is installed on the treatment end 11 according to the correspondence between the color or color component and the auxiliary head 20. Since the color or color combination of the colored light-transmitting part 223 of each third auxiliary head 203 is different, that is, each colored light-transmitting part 223 of the third auxiliary head 203 has a unique corresponding color or color combination, each third auxiliary head 203 can be a different model, such as auxiliary windows 21 of different shapes, that is, the shapes of the auxiliary windows 21 of each third auxiliary head 203 are different; in this way, the skin treatment device can be equipped with more types and models of auxiliary heads 20.

[0058] Reference Figure 6 In some embodiments, the entire area of ​​the colored light-transmitting portion 223 may be a colored area 2231.

[0059] Reference Figure 7 In some embodiments, the colored light-transmitting portion 223 may also include a transparent region 2232 and a colored region 2231, with the area of ​​the colored region 2231 being smaller than the area of ​​the transparent region 2232. Thus, when the third accessory head 203 is installed on the care end 11, the color recognition component 40 receives less colored light reflected from the colored light-transmitting portion 223. This ensures the color recognition component 40's identification of the type of the third accessory head 203 and also helps reduce the amount of compensation required for the colored light received by the color recognition component 40, making it easier for the color recognition component 40 to accurately identify skin color based on the received colored light. In some embodiments, the area of ​​the colored region 2231 may not exceed 5% of the area of ​​the colored light-transmitting portion 223. This results in a very small amount of colored light, having minimal impact on the color recognition component 40's skin color recognition, allowing for even less or no compensation required to maintain accurate skin color recognition.

[0060] In some embodiments, the plurality of accessory heads 20 include a third accessory head 203, wherein the feature portion 22 of the third accessory head 203 is a colored light-transmitting portion 223, and there are multiple third accessory heads 203, each with a different light transmittance of the colored light-transmitting portion 223. For example, there are four third accessory heads 203, and the light transmittance of the colored light-transmitting portions 223 of the four third accessory heads 203 are 60%, 70%, 80%, and 90%, respectively. In this embodiment, the colored light-transmitting portions 223 of each third accessory head 203 can be the same color, or they can be different colors or combinations of colors.

[0061] In this embodiment of the skin treatment device, when the third accessory head 203 is installed on the care end 11, the color recognition component 40 receives colored light reflected from the colored light-transmitting part 223 of the third accessory head 203. By detecting and recognizing the received colored light, the color of the colored light is obtained. Based on the correspondence between the color and the type of accessory head 20, it is determined that the installed accessory head 20 is the third accessory head 203. If multiple third accessory heads 203 have colored light-transmitting portions 223 of the same color, and since the light transmittance of the colored light-transmitting portions 223 of the multiple third accessory heads 203 is different, the intensity of the colored light received by the color recognition component 40 from the colored light-transmitting portions 223 of the third accessory heads 203 will differ when different third accessory heads 203 are installed on the nursing end 11. The color recognition component 40 can further analyze the intensity of the received colored light and, based on the correspondence between the colored light-transmitting portions 223 and the light transmittance of each third accessory head 203, determine which specific third accessory head 203 is installed on the nursing end 11.

[0062] In some embodiments, the skin treatment device is a hair removal device, and the energy output window 1111 is a light emission window. For example, multiple accessory heads 20 may be accessory heads 20 for hair removal on different skin areas (e.g., limbs, armpits, face, pubic area, etc.). In some embodiments, the skin treatment device may also be a skin rejuvenation device or other beauty device.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the content of this application's specification and drawings under the concept of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
