Description

[Technical field]

[0001] [Cross reference to related applications] This disclosure claims priority to a Chinese patent application entitled "Hair Removal Apparatus and Method," filed on December 9, 2021, with application number 202111501079.2, the entire contents of which are incorporated herein by reference.

[0002] The present disclosure relates to the technical field of personal device care, and in particular to hair removal apparatus, methods and related devices. [Background technology]

[0003] Hair removal refers to the use of hair removal techniques and products to remove hair from areas such as the armpits, legs, and hands, resulting in a clean and beautiful effect. Currently, due to the pursuit of fashion, handheld hair removal devices are widely used for daily hair removal in home life. However, most hair removal devices currently on the market require users to actively adjust the light energy level during use, and the direction and angle of the light outlet are fixed, and in actual use, users cannot monitor the state of hair removal and the characteristics of the skin. Therefore, continuous irradiation of strong light often causes the skin around the hair follicles to become red and swollen, resulting in a tingling sensation and worsening the user experience. In addition, during the hair removal process, due to individual differences in the thickness, skin condition, and distribution of body hair, the light source cannot be concentrated on the skin that needs to be removed, resulting in incomplete hair removal or damage to areas that do not need to be removed. In addition, strong light cannot be irradiated on skin with melanin pigmentation, moles, and wounds, and if this part of the skin is not covered during the use of the hair removal device, it may cause damage to the user's skin.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0036] The technical solutions in the embodiments of the present disclosure are clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure, but obviously, the described embodiments are only a part, not all, of the embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts are within the scope of protection of the present disclosure. Example 1 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 disposed at the front end of the housing 10, the lamp assembly 30 is disposed inside the light outlet 20, the light shield 40 is disposed outside the light outlet 20, the control module is connected to the camera assembly to control collection of skin images and identify skin characteristics based on the skin images, the control module is connected to the lamp assembly 30 to adjust the light output level according to the skin characteristics to control the light output intensity and / or light output time, and the control module adjusts the position of the light shield 40 according to the skin characteristics to control the area 90 irradiated on the skin.

[0037] In this embodiment, the control module includes an MCU chip. The MCU chip receives the skin image collected by the camera assembly and identifies the skin characteristics based on stored algorithms and data (any existing technology can be used). The skin characteristics include one or more of skin color, hair follicle size, hair follicle density, melanin pigmentation, moles, and open wounds. According to the skin characteristics such as hair follicle size, hair follicle density, the light output level is automatically adjusted, i.e., the light output intensity and / or the light output time is controlled. Furthermore, the MCU chip determines through the skin characteristics whether there are melanin pigmentation, moles, and open wound areas 100 on the skin, and if there are, these areas need to be covered before applying light to prevent damage to the skin. Furthermore, the MCU chip determines whether there is redness or swelling on the skin during the process of hair removal based on the skin color, and if there is redness or swelling, 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 a network terminal device, such as a mobile phone terminal, a computer terminal, etc. The MCU chip transmits the collected skin images and the recognition results to the network terminal device, and displays and stores the skin images and the recognition results in the software interface of the network terminal device, so that the user can intuitively observe the skin characteristics and hair removal state. The MCU chip can also upload the collected skin images to the network terminal device for image recognition to obtain the results, or directly analyze the skin images to obtain the results.

[0039] Further, the gobo 40 includes one or more gobos, and the gobo 40 is connected to the control module via a telescoping assembly.

[0040] In this embodiment, two light shielding plates 40 are arranged on the left and right. Of course, two light shielding plates 40 can also be arranged on the top and bottom. Since the light shielding plate 40 in this embodiment is composed of two plates, on the one hand, the structure is easy to implement, and on the other hand, when the melanin pigmentation, moles and open wound areas contained in the skin are on one side of the light outlet 20, it is only necessary to control and move one of the light shielding plates 40 to prevent excess light from being blocked, resulting in insufficient hair removal and low hair removal efficiency. In other embodiments, multiple light shielding plates 40 can be provided, such as four on the left, right, top and bottom, as needed, 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 covering the melanin pigmentation, moles and open wound areas.

[0041] Further, the camera assembly includes a camera 50 and a fill light 60. The camera assembly is disposed on the housing or the shading plate 40. Since disposing the camera assembly on the housing is an existing mounting method, a detailed description thereof will be omitted in this embodiment. In this embodiment, the camera assembly is disposed on the shading plate 40, and in particular, the camera 50 and the fill light 60 may be disposed at the center of the shading plate 40.

[0042] In this embodiment, the camera assembly includes two sets, that is, each light shield 40 is provided with one set of camera assembly.

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

[0044] Based on the above hair removal apparatus, as shown in FIG. 9, the hair removal method according to this embodiment includes:

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

[0046] S902, identifying skin features of the current skin 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, adjusting the light output level and / or the irradiation area according to the skin characteristics.

[0048] Specifically, the control entity of the hair removal method may be a control module, specifically including an MCU chip, etc. Specifically, the capacitance sensing located at the light outlet can be used to detect whether it is in close contact with or close to the skin. 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 close contact with or close to the skin, the camera assembly is controlled to collect a skin image, and the control module receives the image to identify skin features, and then activates the lamp assembly to output light.

[0049] In one embodiment, if the identified skin features include only hair follicle size, adjusting the light output level and / or illumination area in response to said skin features may specifically include: Comparing the identified hair follicle size to a preset hair follicle size to determine a hair follicle size grade; obtaining a corresponding light output level based on the hair follicle size grade; Controlling a light output intensity and / or a light output duration of a lamp assembly based on the light output level.

[0050] In another embodiment, if the identified skin characteristics include hair follicle density, adjusting the light output level and / or illumination area in response to said skin characteristics may specifically include: Comparing the identified hair follicle density with a preset hair follicle density to determine a hair follicle density grade; obtaining a corresponding light output level based on the hair follicle density grade; Controlling a light output intensity and / or a light output duration of a lamp assembly based on the light output level.

[0051] In yet another embodiment, where the identified skin characteristics include hair follicle size and hair follicle density, adjusting the light output level and / or illumination area in response to said skin characteristics specifically includes: Comparing the identified hair follicle density with a preset hair follicle density to determine a hair follicle density grade; Comparing the identified hair follicle size to a preset hair follicle size to determine a hair follicle size grade; obtaining a corresponding light output level based on the hair follicle density grade and the hair follicle size grade; Controlling a light output intensity and / or a light output duration of a lamp assembly based on the light output level.

[0052] The following is based on an example in which the skin features include hair follicle size and hair follicle density. According to the size and density of the hair follicles in the current skin area, the hair follicle size is defined to include three types, namely, thin, medium, and thick, and the hair follicle density is defined to include three types, namely, thin, medium, and dense. Then, the light output level is divided into nine levels, and is first divided into three large levels based on the density of the hair follicles, and each large level is divided into three small levels based on the 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 the hair removal effect. If the current hair follicle size is thin and the hair follicle density is thin, the current setting level is automatically decreased by one level to reduce the risk of skin damage.

[0053] Furthermore, when the skin characteristics include skin color, adjusting the light output level and / or the illumination area in response to the skin characteristics may include: The method further includes determining whether the skin color has become red based on the collected skin image, and if so, adjusting a light output level, and controlling a light output intensity and / or a light output time of the lamp assembly based on the adjusted light output level.

[0054] Specifically, when a specific location on the skin becomes red and swollen due to repeated exposure during use, and the control module recognizes that the skin color at the current detection location is significantly redder than the previously recorded skin color, it automatically lowers the current setting level by one level and controls the hair removal device to emit sound / light to warn the user, thereby warning the user to pay attention to the current skin condition.

[0055] Furthermore, when the skin characteristics include hair follicle size and / or hair follicle density, and include melanin pigmentation of hair follicles, moles or open wounds, adjusting the light output level and / or irradiation area according to the skin characteristics can specifically include: Obtaining actual locations of the melanin pigmentation, moles, or open wounds in the hair removal area according to the locations of the melanin pigmentation, moles, or open wounds in the skin image; Controlling a light shielding plate provided outside the light outlet to move it to a position covering the melanin pigmentation, mole, or open wound; obtaining a corresponding light output level based on the hair follicle density and / or hair follicle size; Controlling a light output intensity and / or a light output duration of a lamp assembly based on the light output level.

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

[0057] In this embodiment, the light shielding plate includes two symmetrical plates, each of which is provided with a camera assembly, and when the melanin pigmentation, mole, or open wound is located on one side of the hair removal area, the light shielding plate on the corresponding side is controlled to move (i.e., when the melanin pigmentation, mole, or open wound is identified as being on the left side, the left light shielding plate is controlled to move; when the melanin pigmentation, mole, or open wound is identified as being on the right side, the right light shielding plate is controlled to move) to a position covering the melanin pigmentation, mole, or open wound. The moving distance L of the light shielding plate is as follows:

[0058]

number

[0059] where 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 equally divide the width of the skin image, N represents the number of cells in which the start of the melanin pigmentation, mole, or open wound area is located, and ΔN represents the number of cells occupied by the melanin pigmentation, mole, or open wound area, where X, M, and N are integers.

[0060] As shown in detail in FIG. 11, the movement distance calculated above is only the movement distance of one side shading plate. If both the left and right sides contain melanin pigmentation, moles, or open wound areas, both shading plates need to move corresponding distances based on the size and location of these areas on both sides. In particular, in the example of two shading plates and two cameras, the 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 then

[0061]

number

[0062] It is.

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

[0064] In addition, for an example in which the light shielding plate includes only one piece, and a camera assembly is provided on the light shielding plate, and the melanin pigmentation, mole, or open wound is located in a hair removal area, the light shielding plate is controlled to move to a position covering the melanin pigmentation, mole, or open wound, and the moving distance L of the light shielding plate is as follows:

[0065]

number

[0066] where 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 equally divide the width of the skin image, N represents the number of cells in which the start of the melanin pigmentation, mole, or open wound area is located, and ΔN represents the number of cells occupied by the melanin pigmentation, mole, or open wound area, where X, M, and N are integers.

[0067] That is, in an example where one camera assembly is provided for one light shield, the calculation formula for the movement of the light shield is the same as in the example where two light shields and two camera assemblies are provided.

[0068] Those skilled in the art can easily understand that the hair removal method provided in this embodiment can be realized by software, or by a combination of software and necessary hardware.Therefore, the technical solution according to the embodiment of the present disclosure can be embodied in the form of a software product, which can be stored in a non-volatile storage medium (such as CD-ROM, U-disk, mobile hard disk, etc.) or network, and includes some instructions for making a computing device (which can be a personal computer, a server, a terminal device, a network device, etc.) execute the method according to the embodiment of the present disclosure. Example 2 12 to 19, the hair removal device according to the present embodiment includes a housing 10, and further includes a light outlet 20, a lamp assembly 30, a camera assembly, a light shielding plate 40, and a control module (not shown). The light outlet 20 is disposed at the front end of the housing 10, the lamp assembly 30 is disposed inside the light outlet 20, the light shielding plate 40 is disposed outside the light outlet 20, the control module is connected to the camera assembly to control collection of skin images and identify skin characteristics based on the skin images, the control module is connected to the lamp assembly 30 to adjust a light output level according to the skin characteristics to control light output intensity and / or light output time, and the control module adjusts the position of the light shielding plate 40 according to the skin characteristics to control the area of ​​the skin to be irradiated.

[0069] The difference between this embodiment and the first embodiment is that the camera assembly includes only one set, that is, one of the two light shielding plates 40 is provided with a camera assembly.

[0070] In this embodiment, as shown in FIG. 20, the light shielding plate is composed of two symmetrical plates, and only one light shielding plate is provided with a camera assembly. When the melanin pigmentation, mole, or open wound is located on one side of the hair removal area 100, the light shielding plate on the corresponding side is controlled to move to a position covering the melanin pigmentation, mole, or open wound, and the moving distance L of the light shielding plate is specifically as follows:

[0071]

number

[0072] where 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 equally divide the width of the skin image, N represents the number of cells in which the start of the melanin pigmentation, mole, or open wound area is located, and ΔN represents the number of cells occupied by the melanin pigmentation, mole, or open wound area, where X, M, and N are integers.

[0073] Note that the movement distance calculated above is only for one-sided shader. If both the left and right sides contain melanin pigmentation, moles, or open wound areas, both shaders should be moved by corresponding distances based on the size and location of these areas on both sides. The above X can be adjusted as needed.

[0074] Other configurations of the hair removal device and the specific implementation of the hair removal method according to this embodiment are similar to those of the first embodiment, so this embodiment will not be repeated again.
