Description

Technical Field

[0001] This invention relates to the field of personal care technology, and in particular to a hair removal device and method. Background Technology

[0002] Hair removal refers to the removal of hair from areas such as the armpits, legs, and hands using hair removal techniques and products to achieve a clean and aesthetically pleasing result. Currently, due to the pursuit of fashion, handheld hair removal devices are commonly used for daily hair removal at home. However, most hair removal devices on the market require users to actively adjust the light energy level, and the direction and angle of the light output are fixed. In actual use, because users cannot monitor the hair removal process and skin characteristics, the skin around the hair follicles often becomes red and swollen under continuous strong light exposure, causing a stinging sensation and a poor user experience. Furthermore, during the hair removal process, due to individual differences in the density of body hair, skin condition, and distribution, it is impossible to ensure the light source is concentrated on the skin that needs hair removal, resulting in incomplete hair removal and damage to other areas that do not require hair removal. In addition, strong light exposure should not be applied to skin with pigmentation, moles, or open wounds. If these areas are not covered during the use of a hair removal device, it can cause skin damage. Summary of the Invention

[0042] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0043] (1) The present invention acquires skin images through a camera component and identifies skin features through a control module. It automatically adjusts the light output level (i.e., adjusts the light output intensity and light output time) according to the skin features, and adjusts the area of ​​the skin to be irradiated through a light shield.

[0045] (3) By dividing the skin image into sections and according to the ratio of the skin image size to the actual hair removal area, the present invention can accurately calculate the location of melanin deposition, moles or open wounds, thereby accurately controlling the moving distance of the light-blocking plate. On the one hand, it can cover the areas of melanin deposition, moles or open wounds, and on the other hand, it can minimize the area of ​​the covered skin to avoid affecting the hair removal effect of other skin.

[0046] (4) The camera component of the present invention can be directly mounted on the light-blocking plate. When it is necessary to acquire an image, the light-blocking plate is extended and the camera component is activated. When it is necessary to illuminate, the light-blocking plate is retracted to protect the camera component.

[0069] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0070] Example 1

[0071] See Figures 1 to 8 As shown in the figure, this embodiment of a hair removal device includes a housing 10, and further includes: a light outlet 20, a lamp assembly 30, a camera assembly, a light-blocking plate 40, and a control module (not shown in the figure); 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-blocking plate 40 is disposed outside the light outlet 20; the control module is connected to the camera assembly to control the acquisition of skin images and to identify skin features based on the skin images; the control module is connected to the lamp assembly 30 to adjust the light emission level according to the skin features to control the light intensity and / or light emission time; the control module adjusts the position of the light-blocking plate 40 according to the skin features to control the area 90 of the irradiated skin.

[0072] In this embodiment, the control module includes an MCU chip. The MCU chip receives skin images captured by the camera component and identifies skin features based on stored algorithms and data (any existing technology can be used). These skin features include one or more of skin color, hair follicle size, hair follicle density, melanin deposition, moles, and open wounds. Based on skin features such as hair follicle size and density, the light emission level is automatically adjusted, i.e., the light intensity and / or light emission time is controlled. Furthermore, the MCU chip determines whether there are areas of melanin deposition, moles, or open wounds 100 on the skin based on these skin features. If so, these areas need to be covered before light emission to prevent damage to the skin. Even further, the MCU chip determines whether there is redness or swelling on the skin during the hair removal process based on skin color. If so, the light emission level is automatically lowered, reducing the light intensity and / or the light emission time.

[0073] In another embodiment, the control module further includes a network terminal device, such as a mobile phone terminal or a computer terminal. The MCU chip sends the acquired skin images and recognition results to the network terminal device. The software interface of the network terminal device displays and stores the skin images and recognition results, allowing users to intuitively observe skin features and hair removal status. Alternatively, the MCU chip can either upload the acquired skin images to the network terminal device for image recognition to obtain results, or it can directly analyze the skin images to derive results.

[0074] Furthermore, the light-blocking plate 40 includes one or more pieces; the light-blocking plate 40 is connected to the control module via a telescopic component.

[0075] In this embodiment, the light-blocking plate 40 comprises two pieces arranged on the left and right sides. Of course, the light-blocking plate 40 can also be configured as two pieces, one on top and one on the bottom. In this embodiment, the light-blocking plate 40 is configured as two pieces. Firstly, the structure is easy to implement. Secondly, when areas of skin including melanin deposition, moles, and open wounds are located on one side of the light outlet 20, only one light-blocking plate 40 needs to be moved, preventing the blocking of excess light and thus avoiding insufficient hair removal and low hair removal efficiency. In other embodiments, multiple light-blocking plates 40 can be configured as needed, such as four pieces on the left, right, top, and bottom, or even more smaller pieces. The more light-blocking plates 40 are configured, the smaller the area covered while simultaneously blocking melanin deposition, moles, and open wounds.

[0076] Furthermore, the camera assembly includes a camera 50 and a fill light 60. The camera assembly is disposed on the housing or the light-blocking plate 40. Disposing the camera assembly on the housing is a conventional implementation and will not be specifically described in this embodiment. In this embodiment, the camera assembly is disposed on the light-blocking plate 40; specifically, the camera 50 and the fill light 60 may be disposed at the center of the light-blocking plate 40.

[0077] In this embodiment, the camera assembly includes two sets. That is, each light-blocking plate 40 is equipped with one set of camera assemblies.

[0078] In this embodiment, the hair removal device further includes a telescopic component for driving the light-blocking plate 40 to move. Specifically, the telescopic component may include a motor 70, a screw 80, etc. The control module controls the motor 70 to drive the screw 80 to move, and the screw 80 drives the light-blocking plate 40 to move.

[0079] Based on the hair removal device described above, see [link to relevant documentation]. Figure 9 As shown, this embodiment of a hair removal method includes:

[0080] S901, when the light outlet of the hair removal device is detected to be close to or pressed against the skin, the camera component is controlled to capture a skin image;

[0081] S902, Based on the acquired skin image, identify the skin features of the current skin; the skin features include one or more of the following: skin color, hair follicle size, hair follicle density, melanin deposition, moles, and open wounds;

[0082] S903, adjust the light output level and / or irradiation area according to the skin characteristics.

[0083] Specifically, the control unit of the hair removal method can be a control module, including an MCU chip, etc. Specifically, whether the light outlet is in close contact with the skin can be detected by capacitive sensing at the light outlet. In this embodiment, after the hair removal device is powered on, when the light outlet of the hair removal device is detected to be in close contact with the skin, the camera component is controlled to acquire a skin image. The control module receives the image, identifies the skin features, and then activates the light component to emit light.

[0084] In one embodiment, when the identified skin features only include hair follicle size, adjusting the light output level and / or irradiation area based on the skin features specifically includes:

[0085] The identified hair follicle size is compared with the preset hair follicle size to determine the hair follicle size level;

[0086] Based on the hair follicle size level, the corresponding light emission level is obtained;

[0087] The light intensity and / or light emission time of the lamp assembly are controlled based on the light emission level.

[0088] In another embodiment, when the identified skin feature includes hair follicle density, the light output level and / or irradiation area are adjusted according to the skin feature, specifically including:

[0089] The identified hair follicle density is compared with the preset hair follicle density to determine the hair follicle density level.

[0090] Based on the hair follicle density level, the corresponding light emission level is obtained;

[0091] The light intensity and / or light emission time of the lamp assembly are controlled based on the light emission level.

[0092] In another embodiment, when the identified skin features include hair follicle size and hair follicle density, the light output level and / or irradiation area are adjusted according to the skin features, specifically including:

[0093] The identified hair follicle density is compared with the preset hair follicle density to determine the hair follicle density level.

[0094] The identified hair follicle size is compared with the preset hair follicle size to determine the hair follicle size level;

[0095] Based on the hair follicle density level and hair follicle size level, the corresponding light emission level is obtained;

[0096] The light intensity and / or light emission time of the lamp assembly are controlled based on the light emission level.

[0097] The following explanation considers skin characteristics, including hair follicle size and density. Based on the current hair follicle size and density of the skin area, hair follicle size is defined as fine, medium, and coarse; hair follicle density is defined as sparse, medium, and dense. The light output levels are divided into nine levels, primarily based on hair follicle density into three main levels, and each main level is further divided into three sub-levels based on hair follicle size. If the current hair follicle size is coarse and the density is dense, the setting will automatically increase by one level to ensure hair removal effectiveness. If the current hair follicle size is fine and the density is sparse, the setting will automatically decrease by one level to reduce the risk of skin damage.

[0098] Furthermore, when the skin feature also includes skin color, adjusting the light output level and / or irradiation area based on the skin feature further includes:

[0099] The system determines whether the skin color has turned red based on the collected skin images. If so, it lowers the light output level. Based on the adjusted light output level, it controls the light intensity and / or light output time of the lamp assembly.

[0100] Specifically, if the skin in a certain area becomes red and swollen due to repeated irradiation during use, the control module will identify that the skin color at the current detection location is significantly redder than the previously recorded skin color. In this case, it will automatically lower the current setting by one level and control the hair removal device to emit an audible / visual prompt to alert the user to the current skin condition.

[0101] Furthermore, when the skin characteristics include hair follicle size and / or hair follicle density, and include hair follicle melanin deposition, moles, or open wounds, the light emission level and / or irradiation area are adjusted according to the skin characteristics, specifically including:

[0102] Based on the location of melanin deposits, moles, or open wounds in the skin image, obtain the actual location of the melanin deposits, moles, or open wounds in the hair removal area.

[0103] Control the movement of the light-blocking plate located outside the light outlet to cover melanin deposits, moles, or open wounds;

[0104] Based on the hair follicle density and / or hair follicle size, obtain the corresponding light emission level;

[0105] The light intensity and / or light emission time of the lighting component are controlled based on the light emission level.

[0106] For a detailed flowchart of the hair removal method in this embodiment, please refer to [link / reference]. Figure 10 As shown.

[0107] In this embodiment, the light-blocking plate comprises two symmetrical pieces, and each light-blocking plate is equipped with a camera component. When the melanin deposition, mole, or open wound is located on one side of the hair removal area, the corresponding light-blocking plate is controlled to move to cover the melanin deposition, mole, or open wound (i.e., when the melanin deposition, mole, or open wound is detected to be on the left, the left light-blocking plate is moved; when the melanin deposition, mole, or open wound is detected to be on the left, the right light-blocking plate is moved) to cover the melanin deposition, mole, or open wound; the moving distance of the light-blocking plate is... Specifically as follows:

[0108] ;

[0109] in, This indicates the width of the acquired skin image; This indicates the ratio of the actual size of the hair removal area to the size of the skin image; This indicates the number of grids into which the width of the skin image is divided equally; The grid number indicating the starting location of a melanin deposit, mole, or open wound area; This indicates the number of cells occupied by areas of melanin deposition, moles, or open wounds. , , Take the integer part.

[0110] The calculated movement distance is only the movement distance of a single-sided light-blocking plate. See details below. Figure 11 As shown. If both sides include areas of pigmentation, moles, or open wounds, then both light-blocking panels need to be moved a corresponding distance according to the size and position of these areas. Specifically, for the example of two cameras with two light-blocking panels, the aforementioned... It can be 1, meaning the ratio of the actual hair removal area size to the skin image size is 1. .

[0111] It should be noted that the movement of the light-blocking plate can be from the center to the sides or from the sides to the center. If the camera has finished capturing an image (which can be controlled by fully closing the light-blocking plate before capture), the control module directly controls the corresponding light-blocking plate to move left or right outwards based on the area of ​​melanin deposition, moles, or open wounds. If there are no areas of melanin deposition, moles, or open wounds, the light-blocking plate moves to the end, fully opening the light outlet. In this case, the aforementioned... This refers to the grid number at the starting position from the center of the area with pigmentation, moles, or open wounds. After the camera has captured an image (which can be controlled by fully closing the light-blocking plate before capture), the control module first moves the light-blocking plate all the way to fully open the light outlet, and then controls the corresponding light-blocking plate to move inwards left or right according to the area with pigmentation, moles, or open wounds. In this case, the aforementioned... This refers to the grid number of the starting position of a melaninized area, mole, or open wound, starting from the side.

[0112] Furthermore, in instances where the light-blocking plate comprises only one unit, and a camera assembly is provided on the light-blocking plate, when the melanin deposition, mole, or open wound is located in the hair removal area, the light-blocking plate is controlled to move to cover the melanin deposition, mole, or open wound; the moving distance of the light-blocking plate... Specifically as follows:

[0113] ;

[0114] in, This indicates the width of the acquired skin image; This indicates the ratio of the actual size of the hair removal area to the size of the skin image; This indicates the number of grids into which the width of the skin image is divided equally; The grid number indicating the starting location of a melanin deposit, mole, or open wound area; This indicates the number of cells occupied by areas of melanin deposition, moles, or open wounds. , , Take the integer part.

[0115] That is, in an instance where a light-blocking plate is provided with a camera component, the calculation formula for the movement of the light-blocking plate is the same as in an instance with two light-blocking plates and two camera components.

[0116] Example 2

[0117] See Figures 12 to 19As shown in the figure, this embodiment of a hair removal device includes a housing 10, and further includes: a light outlet 20, a lamp assembly 30, a camera assembly, a light-blocking plate 40, and a control module (not shown in the figure); 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-blocking plate 40 is disposed outside the light outlet 20; the control module is connected to the camera assembly to control the acquisition of skin images and to identify skin features based on the skin images; the control module is connected to the lamp assembly 30 to adjust the light emission level according to the skin features to control the light intensity and / or light emission time; the control module adjusts the position of the light-blocking plate 40 according to the skin features to control the area of ​​skin irradiated.

[0118] The difference between this embodiment and Embodiment 1 is that the camera assembly consists of only one set. That is, the camera assembly is installed on either of the two light-blocking plates 40.

[0119] In this embodiment, see Figure 20 As shown, the light-blocking plate comprises two symmetrical pieces, with only one light-blocking plate equipped with a camera component. When the melanin deposition, mole, or open wound is located on one side of the hair removal area 100, the light-blocking plate on the corresponding side is controlled to move to cover the melanin deposition, mole, or open wound; the moving distance of the light-blocking plate... Specifically as follows:

[0120] ;

[0121] in, This indicates the width of the acquired skin image; This indicates the ratio of the actual size of the hair removal area to the size of the skin image; This indicates the number of grids into which the width of the skin image is divided equally; The grid number indicating the starting location of a melanin deposit, mole, or open wound area; This indicates the number of cells occupied by areas of melanin deposition, moles, or open wounds. , , Take the integer part.

[0122] It should be noted that the calculated movement distance is only for one side of the light-blocking plate. If both sides include areas of pigmentation, moles, or open wounds, then both light-blocking plates need to be moved accordingly based on the size and location of these areas. It can be adjusted as needed.
