Description

Technical Field

[0001] The invention relates to a hair removal device, a working method thereof and a storage medium. Background Art

[0002] Laser hair removal device is a beauty device for hair removal. The working principle of the hair removal device is to use the photothermal power principle, utilize the heat energy emitted by the laser, and irradiate the skin to allow the melanin on the hair to absorb the laser energy, thereby converting it into heat energy and penetrating deeply into the hair follicles, causing the skin hair follicles to be damaged and the hair to lose its ability to regenerate, thereby achieving the purpose of hair removal.

[0003] For example, the Chinese utility model patent "A hair removal device with adjustable output frequency" with the authorization announcement number CN219184088U (application number 202223489036.X) includes a laser emitting device, a detachable and replaceable light head and a sensing device. A marking piece is provided on the light head, and the sensing device adjusts the output power of the laser emitting device based on the sensing signal of the marking piece. Although the hair removal device can adjust the output power of the laser emitting device, it is determined based on the detection of the marking piece on the light head, and it is not determined based on the hair characteristics of the area where hair removal is required. When the user does not replace the light head for a long time or does not know how to determine the light head based on what conditions, it will cause the laser power to be mismatched with the hair characteristics of the hair removal area. Even if the user is familiar with the conditions for replacing the light head, the disassembly and installation operations are relatively complicated. And when the light head is determined, the light outlet is fixed, and the light range cannot be adjusted according to the distribution area of ​​the hair, and precise adjustment cannot be achieved to adapt to the hair removal needs of different areas. Summary of the invention

[0009] The two reflectors are axially symmetrically arranged on the upper and lower sides of the pulse lamp, and the driving mechanism is drivingly connected to the reflectors to drive the reflectors to swing up and down relative to the light outlet.

[0010] The structure is simple. The driving mechanism comprises a motor and a connecting shaft. The connecting shaft is connected to the driving end of the motor and is connected to the reflective plate.

[0011] In order to ensure the stability of driving the reflector, the connecting shaft is connected to the middle of the side of the reflector.

[0014] Preferably, at least two image collectors are provided and are evenly distributed within the range of the light outlet.

[0015] The technical solution adopted by the present invention to solve the third technical problem is: a working method of a hair removal device, characterized in that: the hair removal device as claimed in claim 5 or 6 is used, and the working method of the hair removal device comprises the following steps:

[0018] Control the rotation of the reflector so that the light emission range of the pulse lamp from the light outlet matches the hair distribution range;

[0019] The pulse lamp is controlled to work and hair removal is performed on the hair within the hair distribution range.

[0020] In order to improve the hair removal effect, the hair density is obtained according to the skin image, and the working power of the pulse lamp is adjusted according to the hair density.

BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Figure 1 It is a stereoscopic diagram of the hair removal device in the embodiment of the present invention.

[0031] Figure 2 It is a three-dimensional exploded view of the hair removal device in the embodiment of the present invention. DETAILED DESCRIPTION

[0032] The present invention is further described in detail below with reference to the accompanying drawings.

[0033] like Figure 1 and Figure 2 As shown, the hair removal device in this embodiment includes a casing 1 with a light outlet 11, a light-transmitting plate 2 covering the light outlet 11, a pulse lamp 3 arranged in the casing 1 corresponding to the light outlet 11, a control module arranged in the casing 1, two reflectors 4 arranged in the casing 1, a driving mechanism 5 arranged corresponding to each reflector 4, and an image collector 8 arranged in the casing 1 facing the light outlet 11, wherein the pulse lamp 3, each driving mechanism 5, and the image collector 8 are all connected to the control module by electrical signals.

[0034] For easy installation, a mounting seat 652 extending along the length direction of the pulse lamp 3 is provided in the housing 1 behind the pulse lamp 3, and a reflector 7 with an arc-shaped cross section extending along the length direction of the pulse lamp 3 is provided on the mounting seat 652, so that the light irradiated by the pulse lamp 3 to the rear can be re-emitted from the light outlet 11 through the action of the reflector 7, thereby providing irradiation light intensity. The pulse lamp 3 and the driving mechanism 5 are both arranged on the mounting seat 652.

[0035] In order to facilitate the adjustment of the emission range of the pulse lamp 3 from the light outlet 11, the two reflectors 4 in this embodiment are axially symmetrically arranged on the upper and lower sides of the pulse lamp 3, and the driving mechanism 5 is connected to the reflector 4 to drive the reflector 4 to swing up and down relative to the light outlet 11. The driving mechanism 5 drives the two reflectors 4 to swing up and down, thereby adjusting the light emission range of the pulse lamp 3. When the rear ends of the two reflectors 4 are butted together, the two reflectors 4 are in a V-shaped posture opened forward, and the emission range of the pulse lamp 3 reaches the maximum. When the front sides of the two reflectors 4 are both tilted upward, the emission range of the pulse lamp 3 is in the upper area of ​​the light outlet 11, and the emission range is different based on the different inclination angles. When the front sides of the two reflectors 4 are both tilted downward, the emission range of the pulse lamp 3 is in the lower area of ​​the light outlet 11, and the emission range is different based on the different inclination angles. When the front sides of the two reflectors 4 are relatively close to each other, the emission range of the pulse light decreases, and the emission range gradually decreases based on the decrease in the distance between the two. Based on this, by driving the two reflectors 4 up and down, the different irradiation ranges at the light outlet 11 can be adjusted. The reflector 4 is provided with a reflective layer on the side facing the pulse lamp 3, which can reflect the light emitted by the pulse light thereon, thereby achieving the purpose of enhancing the intensity of the emitted light.

[0036] The structure is simple. The driving mechanism 5 in this embodiment includes a motor 51 and a connecting shaft 52. The connecting shaft 52 is connected to the driving end of the motor 51 and connected to the reflector 4. In order to ensure the stability of driving the reflector 4, the connecting shaft 52 is connected to the middle of the side of the reflector 4.

[0037] When performing hair removal, the image collector 8 is used to collect the skin image of the skin to be hair removed at the light outlet 11. The skin image is processed and calculated using the existing image processing algorithm, and the distribution range of hair, the density of hair and the relevant characteristic information of the light can be obtained, so as to facilitate the adjustment of the emission range of the pulse light and the working power of the pulse lamp 3. In order to facilitate the adjustment of the working power of the pulse lamp 3, a power adjustment circuit unit connected to the electrical signal of the pulse lamp 3 is provided in the control module. When working, the power adjustment circuit unit adjusts the working parameters based on the instructions of the control module, so as to achieve the purpose of adjusting the input power supplied to the pulse lamp 3.

[0038] The number of image collectors 8 is specifically determined according to the size of the area of ​​the light outlet 11. For example, when the area of ​​the light outlet 11 is large, one image collector 8 cannot collect all images of the skin located at the light outlet 11. In this case, at least two image collectors 8 can be provided and evenly distributed within the range of the light outlet 11. Then the control module can control the collection range of each image collector 8 so that the images collected by each image collector 8 can be combined into a complete skin image.

[0039] The working method of the aforementioned hair removal device comprises the following steps.

[0040] First, the user holds the hair removal device and aligns the light outlet 11 with the skin to be treated with hair removal. Then the control module controls the image collector 8 to collect the skin image at the light outlet 11. The control module obtains the hair distribution range according to the skin image based on the existing image processing algorithm. Based on the hair distribution range, the reflector 4 can be controlled to rotate so that the light output range of the pulse lamp 3 from the light outlet 11 matches the hair distribution range; the pulse lamp 3 is controlled to work and the hair within the hair distribution range is removed.

[0041] For ordinary hair removal devices, the reflector 4 can be directly adjusted so that the light output range of the pulse lamp 3 from the light output port 11 matches the distribution range of all hairs in the skin to be treated with hair removal, and the pulse lamp 3 can be controlled to perform hair removal according to a fixed working power.

[0042] However, different people and different skin locations have different hair densities. If the pulse lamp 3 is controlled to work at a fixed working power, the skin may feel uncomfortable due to excessively high power or the hair removal time may be long and the effect may be poor due to too low power.

[0043] Based on this, in order to better match hair of different densities, improve the hair removal effect, and at the same time ensure the comfort during the hair removal process as much as possible, in this embodiment, the control module obtains the hair density on the skin to be removed based on the processing and calculation of the skin image, and adjusts the working power of the pulse lamp 3 according to the hair density, so that the working power of the pulse lamp 3 is more matched with the hair density, while ensuring the hair removal effect and comfort requirements.

[0044] However, the hair on the skin to be depilated may have a variety of hair density distributions. Based on this, any of the following methods can be used in this embodiment to achieve refined processing of the hair and improve user experience.

[0045] First, preset different hair density ranges and preset the working powers of the pulse lamp 3 corresponding to different hair density ranges;

[0046] One method is: perform hair density calculation processing on the skin image, and divide the skin image into hair distribution areas in different hair density ranges corresponding to different preset hair density ranges. Because the light emission range of the pulse lamp 3 in this embodiment is adjustable up and down, the division of the hair distribution areas in different hair density ranges is achieved based on the up and down directions, and then the hair distribution areas in different hair density ranges in the up and down directions are obtained. The reflector 4 is controlled to rotate so that the light emission range of the pulse lamp 3 from the light outlet 11 matches each hair distribution area respectively. When matching a hair distribution area, the pulse lamp 3 is controlled to work according to the working power of the pulse lamp 3 corresponding to the hair density range of the current hair distribution area.

[0047] For example, if based on the processing of the skin image, it can be known that the range of hair on the skin to be depilated has three hair distribution areas in different hair density ranges, namely, upper, middle and lower. Then, the driving mechanism 5 is used to drive the reflector 4 to make the light emission range of the pulse light match the range of hair in the upper hair distribution area, and then the pulse lamp 3 is controlled to work with the working power corresponding to its hair density, thereby achieving the depilation process. Then, based on the same means, the depilation process is performed in turn for the range of hair in the middle hair distribution area and the range of hair in the lower hair distribution area.

[0048] Another method is to divide the area first, and then perform hair removal treatment on each area separately.

[0049] Specifically, the skin image is divided into at least two areas from top to bottom, and the hair density calculation process is performed on the skin image of each area to obtain the average hair density data Mi corresponding to each area, where i is the area number, and the pulse lamp 3 working power Pi corresponding to each area is obtained according to the hair density range of the average hair density data Mi.

[0050] The reflector 4 is controlled to rotate so that the light emission range of the pulse lamp 3 from the light outlet 11 matches the hair distribution range corresponding to each area. When matching the hair distribution range corresponding to an area, the pulse lamp 3 is controlled to work according to the working power Pi of the pulse lamp 3 in the current area.

[0051] However, there may be adjacent areas in the same hair density range. If they are treated separately, the efficiency will be low. Based on this, in order to reduce the number of working areas and improve the hair removal efficiency, n adjacent areas in the same hair density range are merged into a combined action area, and the reflector 4 is controlled to rotate so that the light output range of the pulse lamp 3 from the light output port 11 matches the hair distribution range corresponding to the combined action area, and the pulse lamp 3 is controlled to work according to the working power of the pulse lamp 3 corresponding to the hair density range of the combined action area.

[0052] The present invention also relates to a storage medium storing a computer program, characterized in that when the computer program is read and executed by a processor, the working method of the hair removal device as described above is implemented.

[0053] The hair removal device in the present invention can adjust the light output range of the pulse lamp 3 by driving the reflector 4 through the driving mechanism 5, and then adjust the light output range based on the range of hair distribution, so as to make the hair removal treatment range more accurate, avoid the hairless parts from being heated by the pulse light, and improve the comfort during the hair removal process.

[0054] On this basis, the hair distribution range can be determined by the image collector 8, thereby realizing the automation and accuracy of the light output range adjustment. The image collector 8 can also detect the hair distribution density, and then adjust the power of the pulse lamp 3 based on the hair distribution density, so that the hair removal treatment is more targeted and the hair removal effect is better.
