Description

Technical Field

[0001] 〔Cross - References to Related Applications〕 This disclosure claims priority to a Chinese patent application with application number 202111501079.2, filed on December 9, 2021, and titled "Hair Removal Device and Hair Removal Method", and all the contents of the Chinese patent application are incorporated herein by reference.

[0002] This disclosure relates to the technical field of personal device care, and particularly to hair removal devices, hair removal methods, and related devices.

Background Art

[0003] Hair removal refers to using hair removal techniques and products to remove hair on parts such as the armpits, legs, and hands, bringing a clean and beautiful effect. Currently, due to the pursuit of fashionability, handheld hair removal devices are widely used for daily hair removal in family life. However, most of the currently commercially available hair removal devices require the user to actively adjust the light energy level during use, and the direction and angle of the light outlet are fixed. In actual use, the user cannot monitor the hair removal state and skin characteristics. Therefore, when continuously irradiating strong light, the skin around the hair follicles often turns red or swells, resulting in a tingling sensation and deteriorating the user experience. Also, during the hair removal process, due to individual differences in hair density, skin condition, and distribution, it is impossible to ensure the concentration of the light source on the skin that requires hair removal, resulting in incomplete hair removal or damage to parts that do not require hair removal. Moreover, strong light cannot be irradiated on skin with melanin pigmentation, moles, or wounds. If this part of the skin is not covered during the use of the hair removal device, it may damage the user's skin.

[Modes for carrying out the invention]

[0036] The technical solutions in the embodiments of this disclosure are described below clearly and completely with reference to the accompanying drawings of the embodiments of this disclosure, although obviously the embodiments described are only a selection, and not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art without creative effort based on the embodiments of this disclosure are within the scope of the protection of this disclosure. [Example 1] Referring to Figures 1 to 8, the hair removal device in this embodiment includes a housing 10 and further includes a light outlet 20, a lamp assembly 30, a camera assembly, a light shield 40, and a control module (not shown). The light outlet 20 is located at the front end of the housing 10, the lamp assembly 30 is located inside the light outlet 20, the light shield 40 is located outside the light outlet 20, the control module is connected to the camera assembly to control the collection of skin images and to identify skin features based on the skin images, the control module is connected to the lamp assembly 30 to control the light output intensity and / or light output time by adjusting the light output level according to the skin features, and the control module controls the area 90 irradiated onto the skin by adjusting the position of the light shield 40 according to the skin features.

[0037] In this embodiment, the control module includes an MCU chip. The MCU chip receives skin images collected by the camera assembly and identifies skin features based on stored algorithms and data (any existing technology can be used). The skin features include one or more of the following: skin color, hair follicle size, hair follicle density, melanin pigmentation, moles, and open wounds. Depending on the skin features such as hair follicle size and hair follicle density, the light output level is automatically adjusted, i.e., the light output intensity and / or light output time are controlled. Furthermore, the MCU chip determines, based on the skin features, whether there are melanin pigmentation, moles, and open wound areas 100 on the skin, and if they are present, these areas should be covered before exposure to light to prevent damage to the skin. Furthermore, based on skin color, the MCU chip determines whether there is redness or swelling on the skin during the hair removal process, and if there is redness or swelling, it automatically reduces the light output level, reduces the light output intensity, and / or shortens the light output time.

[0038] In another embodiment, the control module also includes network terminal devices such as mobile phone terminals and computer terminals. The MCU chip transmits the collected skin images and recognition results to the network terminal device, and displays and saves the skin images and recognition results on the network terminal device's software interface, allowing the user to intuitively observe skin characteristics and hair loss status. The MCU chip can also upload the collected skin images to the network terminal device for image recognition to obtain results, or it can directly analyze the skin images to obtain results.

[0039] Furthermore, the light-shielding plate 40 includes one or more light-shielding plates, and the light-shielding plate 40 is connected to the control module via an expandable assembly.

[0040] In this embodiment, two light-shielding plates 40 are arranged on the left and right sides. Of course, two light-shielding plates 40 can also be arranged vertically. In this embodiment, since the light-shielding plates 40 consist of two plates, on the one hand, the structure is easy to implement, and on the other hand, if melanin pigmentation, moles, and open wound areas in the skin are on one side of the light outlet 20, only one of the light-shielding plates 40 needs to be controlled and moved to prevent excess light from being blocked, which would result in insufficient hair removal or low hair removal efficiency. In other embodiments, multiple light-shielding plates 40 can be provided as needed, such as four plates on the left, right, top, and bottom, or more small light-shielding plates 40 can be provided, and the more light-shielding plates 40 are provided, the smaller the area covered while still covering melanin pigmentation, moles, and open wound areas.

[0041] Furthermore, the camera assembly includes a camera 50 and a fill light 60. The camera assembly is positioned on the housing or the light shield 40. Since positioning the camera assembly on the housing is an existing mounting method, a detailed explanation is omitted in this embodiment. In this embodiment, the camera assembly is positioned on the light shield 40, and in particular, the camera 50 and the fill light 60 may be positioned in the center of the light shield 40.

[0042] In this embodiment, the camera assembly includes two sets. That is, each light-shielding plate 40 is provided with one set of camera assemblies.

[0043] In this embodiment, the hair removal device further includes a telescopic assembly for driving the light-shielding plate 40 to move. Specifically, the telescopic assembly may include a motor 70, a screw 80, and the like. The control module controls the motor 70 to move the screw 80, and the screw 80 moves the light-shielding plate 40.

[0044] Based on the hair removal device described above, the hair removal method according to this embodiment, as shown in Figure 9, includes the following:

[0045] S901, when it detects that the light outlet of the hair removal device is in close contact with or near the skin, controls the camera assembly to collect a skin image.

[0046] S902 identifies the current skin features based on the collected skin images, the skin features including one or more of skin color, hair follicle size, hair follicle density, melanin pigmentation, moles, and open wounds.

[0047] S903, adjust the light output level and / or irradiation area according to the skin characteristics.

[0048] Specifically, the control entity for the hair removal method may be a control module, which specifically includes an MCU chip or the like. Specifically, it is possible to detect whether the light outlet is in contact with or close to the skin using a capacitive sensing located at the light outlet. After the hair removal device of this embodiment is powered on, when it is detected that the light outlet of the hair removal device is in contact with or close to the skin, the camera assembly is controlled to collect a skin image, the control module receives the image and identifies skin features, and then the lamp assembly is activated to output light.

[0049] In one embodiment, if the identified skin features include only hair follicle size, adjusting the light output level and / or irradiation area according to the skin features specifically means, The identified hair follicle size is compared to a pre-set hair follicle size to determine the hair follicle size grade, and Based on the aforementioned hair follicle size grade, the corresponding light output level is obtained, This includes controlling the light output intensity and / or light output duration of the lamp assembly based on the aforementioned light output level.

[0050] In another embodiment, if the identified skin features include hair follicle density, adjusting the light output level and / or irradiation area according to the skin features specifically means, The hair follicle density grade is determined by comparing the identified hair follicle density with a pre-set hair follicle density. Based on the aforementioned hair follicle density grade, the corresponding light output level is obtained. This includes controlling the light output intensity and / or light output duration of the lamp assembly based on the aforementioned light output level.

[0051] In yet another embodiment, if the identified skin features include hair follicle size and hair follicle density, adjusting the light output level and / or irradiation area according to the skin features specifically means, The hair follicle density grade is determined by comparing the identified hair follicle density with a pre-set hair follicle density. The identified hair follicle size is compared to a pre-set hair follicle size to determine the hair follicle size grade, and Based on the aforementioned hair follicle density grade and hair follicle size grade, the corresponding light output level is obtained, This includes controlling the light output intensity and / or light output duration of the lamp assembly based on the aforementioned light output level.

[0052] The following explanation is based on an example where skin characteristics include hair follicle size and hair follicle density. Depending on the size and density of hair follicles in the current skin area, hair follicle size is defined as including three types: thin, medium, and thick, and hair follicle density is defined as including three types: sparse, medium, and dense. Then, the light output level is divided into nine levels, first divided into three large levels based on hair follicle density, and then each large level is divided into three small levels based on hair follicle size. If the current hair follicle size is thick and the hair follicle density is dense, the current setting level is automatically increased by one level to ensure hair removal effectiveness. If the current hair follicle size is thin and the hair follicle density is sparse, the current setting level is automatically decreased by one level to reduce the risk of skin damage.

[0053] Furthermore, if the skin characteristics include skin color, adjusting the light output level and / or irradiation area according to the skin characteristics is: The system further includes determining, based on the collected skin images, whether the skin color has become red, and if so, adjusting the light output level, and controlling the light output intensity and / or light output time of the lamp assembly based on the adjusted light output level.

[0054] Specifically, if repeated exposure during use causes redness and swelling in a specific area of ​​the skin, and the control module recognizes that the skin color at the currently detected location is significantly redder than previously recorded, it will automatically lower the current setting level by one level and control the hair removal device to emit sound / light as a warning, alerting the user to pay attention to the current skin condition.

[0055] Furthermore, if the skin features include hair follicle size and / or hair follicle density, and include melanin pigmentation, moles, or open wounds in the hair follicles, adjusting the light output level and / or irradiation area according to the skin features specifically means, To obtain the actual location of melanin pigmentation, moles, or open wounds within the hair loss area, according to the location of melanin pigmentation, moles, or open wounds within the skin image, Controlling a light-shielding plate located outside the light outlet to move it to a position that covers melanin pigmentation, moles, or open wounds, Based on the aforementioned hair follicle density and / or hair follicle size, the corresponding light output level is obtained, This includes controlling the light output intensity and / or light output duration of the lamp assembly based on the aforementioned light output level.

[0056] A detailed flowchart of the hair removal method according to this embodiment is shown in Figure 10.

[0057] In this embodiment, the light-shielding plates include two symmetrical plates, each equipped with a camera assembly. When the melanin pigmentation, mole, or open wound is located on one side of the hair removal area, the corresponding light-shielding plate is controlled (i.e., if the melanin pigmentation, mole, or open wound is identified as being on the left side, the left light-shielding plate is controlled and moved; if the melanin pigmentation, mole, or open wound is identified as being on the right side, the right light-shielding plate is controlled and moved) to a position that covers the melanin pigmentation, mole, or open wound. The distance L of the light-shielding plates is as follows:

[0058]

number

[0059] Here, D represents the width of the acquired skin image, X represents the ratio of the size of the actual hair removal area to the size of the skin image, M represents the number of cells that divide the width of the skin image equally, N represents the number of cells in which the starting position of melanin pigmentation, moles, or open wound areas is located, and ΔN represents the number of cells occupied by melanin pigmentation, moles, or open wound areas. X, M, and N are integers.

[0060] As shown in detail in Figure 11, the distance calculated above is only the distance traveled by one side of the light-shielding plate. If melanin pigmentation, moles, or open wound areas are included on both the left and right sides, both light-shielding plates must each move by a corresponding distance based on the size and position of these areas on both sides. In particular, in the example of two light-shielding plates and two cameras, X may be 1, i.e., the ratio of the size of the actual hair removal area to the size of the skin image is 1, and in this case,

[0061]

number

[0062] That is the case.

[0063] The movement of the light-shielding plate may be from the center to both sides, or from both sides to the center. After the camera collects an image (it can be controlled to start collecting images after the light-shielding plate is completely closed), if the control module directly controls the corresponding light-shielding plate to move left or right according to the melanin pigmentation, mole, or open wound area, if there is no melanin pigmentation, mole, or open wound area, the light-shielding plate is moved to the edge so that the light outlet is fully open. In this case, N refers to the number of cells in which the starting position of the melanin pigmentation, mole, or open wound area, starting from the center, is located. After the camera collects an image (it can be controlled to start collecting images after the light-shielding plate is completely closed), the control module first moves the light-shielding plate to the edge to fully open the light outlet, and then moves the corresponding light-shielding plate inward to the left or right according to the melanin pigmentation, mole, or open wound area. In this case, N refers to the number of cells in which the starting position of the melanin pigmentation, mole, or open wound area, starting from the side, is located.

[0064] Furthermore, in the case of an example in which only one light-shielding plate is included, and a camera assembly is provided on the light-shielding plate, and the melanin pigmentation, mole, or open wound is located in the hair loss area, the light-shielding plate is controlled to move to a position that covers the melanin pigmentation, mole, or open wound, and the movement distance L of the light-shielding plate is as follows.

[0065]

number

[0066] Here, D represents the width of the acquired skin image, X represents the ratio of the size of the actual hair removal area to the size of the skin image, M represents the number of cells that divide the width of the skin image equally, N represents the number of cells in which the starting position of melanin pigmentation, moles, or open wound areas is located, and ΔN represents the number of cells occupied by melanin pigmentation, moles, or open wound areas. X, M, and N are integers.

[0067] That is, in the example where one camera assembly is provided on one light-shielding plate, the formula for calculating the movement of the light-shielding plate is the same as in the example with two light-shielding plates and two camera assemblies.

[0068] Those skilled in the art will readily understand that the hair removal method provided in this embodiment can be implemented by software or by a combination of software and necessary hardware. Accordingly, the technical solutions according to the embodiments of the present disclosure can be embodied in the form of a software product which can be stored on a non-volatile storage medium (such as a CD-ROM, U disk, or mobile hard disk) or on a network and includes several instructions for causing a computing device (which may be a personal computer, server, terminal device, or network device) to perform the method according to the embodiments of the present disclosure. [Example 2] Referring to Figures 12 to 19, the hair removal device according to this embodiment includes a housing 10, and further includes a light outlet 20, a lamp assembly 30, a camera assembly, a light shield 40, and a control module (not shown). The light outlet 20 is located at the front end of the housing 10, the lamp assembly 30 is located inside the light outlet 20, the light shield 40 is located outside the light outlet 20, the control module is connected to the camera assembly to control the collection of skin images and to identify skin features based on the skin images, the control module is connected to the lamp assembly 30 to control the light output intensity and / or light output time by adjusting the light output level according to the skin features, and the control module controls the area irradiated onto the skin by adjusting the position of the light shield 40 according to the skin features.

[0069] The difference between this embodiment and Embodiment 1 is that the camera assembly includes only one set. That is, the camera assembly is provided on one of the two light-shielding plates 40.

[0070] In this embodiment, as shown in Figure 20, the light-shielding plates consist of two symmetrical plates, and a camera assembly is provided on only one of the light-shielding plates. When the melanin pigmentation, moles, or open wounds are located on one side of the hair removal area 100, the corresponding light-shielding plate is controlled to move to a position that covers the melanin pigmentation, moles, or open wounds. The movement distance L of the light-shielding plates is specifically as follows.

[0071]

number

[0072] Here, D represents the width of the acquired skin image, X represents the ratio of the size of the actual hair removal area to the size of the skin image, M represents the number of cells that divide the width of the skin image equally, N represents the number of cells in which the starting position of melanin pigmentation, moles, or open wound areas is located, and ΔN represents the number of cells occupied by melanin pigmentation, moles, or open wound areas. X, M, and N are integers.

[0073] Note that the movement distance calculated above is only for the single-sided light-shielding plate. If melanin pigmentation, moles, or open wound areas are present on both the left and right sides, both light-shielding plates must be moved by the corresponding distance based on the size and location of these areas on both sides. The above X can be adjusted as needed.
