The device includes a handle and a head, with a light outlet formed on the end surface of the head and a light-emitting device disposed within the head for emitting light toward the light outlet.

[0004] The skin care devices provided by the aforementioned related art have the following drawbacks in specific applications: The placement of the light-emitting device on the head and the emission of light from the end face of the head results in a relatively large head size and a relatively small light-emitting area. Increasing the light-emitting area and the volume of the light-emitting device further increases the size and weight of the head, making the skin care device bulky and inconvenient to use. Summary of the Invention

[0005] The main purpose of this application is to propose a skin care device, aiming to solve the technical problem of large head size of skin care devices in related technologies.

[0006] To achieve the above objectives, the present application proposes a skin care device, comprising:

[0007] The handle housing includes a top portion, a bottom portion, and a peripheral side portion located between the top portion and the bottom portion, wherein the peripheral side portion is connected to the top portion and the bottom portion, and the peripheral side portion, the top portion, and the bottom portion enclose an accommodating cavity, wherein the surface area of the peripheral side portion is greater than the surface area of the top portion, and / or the surface area of the peripheral side portion is greater than the surface area of the bottom portion, and the peripheral side portion is provided with a light outlet communicating with the accommodating cavity;

[0010] The skin care device of the technical solution of the present application can achieve a design effect of lateral light emission of the skin care device by arranging the light outlet on the circumferential side of the handle shell where the surface area is larger than the bottom and / or top surface area, and arranging the light-emitting device in the accommodating cavity of the handle shell and emitting light toward the light outlet. In addition, the side area of the handle shell can be fully utilized to increase the light emission area of the skin care device and achieve a large-area light emission effect. In addition, by arranging the light-emitting device in the accommodating cavity of the handle shell, the space in the handle shell of the skin care device can be fully utilized to arrange a large-volume light-emitting device, which is conducive to simplifying the head of the skin care device, effectively avoiding the undesirable phenomenon of the head of the skin care device being too large and top-heavy, and thus facilitating handheld operation by the user.

[0032] In some embodiments, the first air inlet is formed on the peripheral side portion, which can realize side air intake, facilitate the configuration of a large-sized air inlet, and ensure the heat dissipation effect and normal operation of the light-emitting device.

[0033] In some embodiments, the first air inlet and the light outlet are arranged on the same side, thereby facilitating air intake over a large area, while shortening the distance between the air inlet, the heat dissipation device and the light outlet, thereby improving the heat dissipation effect.

[0034] In some embodiments, the handle housing has a second air inlet, which is formed at the bottom. The air entering from the second air inlet can dissipate heat from the components at the bottom of the handle housing, thereby improving the heat dissipation effect and facilitating handheld use.

[0063] The present application provides a skin care device, which is mainly used for caring for skin, and the skin may be facial skin, hand skin, leg skin or skin of other parts of the human body.

[0064] Reference Figure 1 ,as well as Figures 3 to 6The skin care device provided in one embodiment of the present application includes a handle housing 10, a light emitting device 20 and a light-transmitting skin-adhering member 30. The handle housing 10 includes a top 11, a bottom 12 and a peripheral side portion 13 located between the top 11 and the bottom 12. The peripheral side portion 13 is connected to the top 11 and the bottom 12, and the peripheral side portion 13, the top 11 and the bottom 12 surround a receiving cavity 15. The surface area of the peripheral side portion 13 is larger than that of the top 11, and / or the surface area of the peripheral side portion 13 is larger than that of the bottom 12. The peripheral side portion 13 is provided with a light outlet 14 connected to the receiving cavity 15. The light emitting device 20 is provided in the receiving cavity 15 and is used to emit light toward the light outlet 14. The light-transmitting skin-adhering member 30 is installed at the light outlet 14. The light-transmitting skin-adhering member 30 is used to allow light emitted by the light emitting device 20 to pass through so as to be emitted out of the handle housing 10.

[0065] When the skin care device is in use, the light emitting device 20 located in the accommodating cavity 15 of the handle housing 10 emits light of a specific wavelength, and then the light is emitted from the outside of the handle housing 10 through the light-transmitting skin-contacting member 30 provided at the light outlet 14, and acts on the skin to achieve the purpose of skin care. Particularly, since the light outlet 14 of the skin care device is provided on the circumferential side portion 13 of the handle housing 10, whose surface area is larger than the surface area of the bottom 12 and / or the surface area of the top 11, the light emitting device 20 is provided in the accommodating cavity 15 of the handle housing 10 and emits light toward the light outlet 14, so that the skin care device can achieve lateral light emission, and can make full use of the side area of the handle housing 10, increase the light emission area of the skin care device, achieve the effect of large-area light emission, and improve skin care efficiency, such as hair removal efficiency. In addition, the light-emitting device 20 in the skin care device is arranged in the accommodating cavity 15 of the handle shell 10, which can fully utilize the space in the handle shell 10 to arrange a large-volume light-emitting device 20, which is conducive to simplifying the head of the skin care device and effectively avoiding the problem of the head of the skin care device being too large and top-heavy, thereby facilitating user hand-held operation.

[0066] The handle shell 10 in the skin care device serves as the main external frame of the skin care device, and is used to install and protect the various components of the skin care device. Specifically, the handle shell 10 includes a top 11, a bottom 12, and a peripheral side portion 13 located between the top 11 and the bottom 12. The peripheral side portion 13 is connected to the top 11 and the bottom 12, and is surrounded by the top 11 and the bottom 12 to form a receiving cavity 15. The various components of the skin care device can be accommodated in the receiving cavity 15 of the handle shell 10 to form a whole. The handle shell 10 can also serve as a protective shell to protect the various internal components. When the skin care device is used, the handle shell 10 is generally used as a hand-held portion. The handle shell 10 can be designed to be a cylindrical shape or other shape suitable for hand-holding.

[0067] The light outlet 14 of the skin care device is located on the peripheral side portion 13 of the handle housing 10. In some embodiments, the peripheral side portion 13 includes a first side portion 131, a second side portion 132 disposed opposite the first side portion 131, and a third side portion 133 connecting the first side portion 131 and the second side portion 132. The surface area of the third side portion 133 is smaller than the surface area of the first side portion 131, the surface area of the third side portion 133 is smaller than the surface area of the second side portion 132, the surface area of the third side portion 133 is larger than the surface area of the top portion 11, and the surface area of the third side portion 133 is larger than the surface area of the bottom portion 12. The light outlet 14 is located on the first side portion 131 or the second side portion 132. Through the above structural arrangement, the large side area of the handle housing 10 can be fully utilized to increase the light output area of the side light, effectively achieving a large-area light output effect. Of course, in some embodiments, the light outlet 14 can also be located on other side portions of the peripheral side portion 13, which can also utilize the side portion of the handle housing 10 to increase the light output area to a certain extent, achieving a large-area light output effect.

[0068] In some embodiments, the distance between the light outlet 14 and the top 11 is smaller than the distance between the light outlet 14 and the bottom 12. Through this structural setting, sufficient hand-holding area can be left for users to use the skin care device. The area section where the light outlet 14 is located on the handle shell 10 is used as the working section, and the remaining area sections can be used as hand-holding sections, which can facilitate user hand-held operation and facilitate the control of the translucent skin-contacting part 30 at the light outlet 14 of the device to fit the skin for skin care care.

[0069] In order to facilitate handheld operation and skin-friendly use, the distance from the center of gravity of the skin care device to the top 11 can be designed to be greater than the distance to the bottom 12, so that gravity can be used to fit the skin during use, making it easier to hold the device in hand.

[0070] In some embodiments, the peripheral side portion 13 may be designed to have a protruding boss 1312, with the light outlet 14 disposed on the boss. Specifically, the first side portion 131 of the handle housing 10 may be designed to include a first surface 1311 and a boss 1312 protruding from a portion of the first surface 1311. The boss 1312 has a contact surface 1313 spaced apart from the first surface 1311, and the light outlet 14 is formed on the contact surface 1313. Since the thickness direction (or light emitting direction) of the light outlet 14 generally includes at least a light-transmitting skin-contacting part 30, a light-emitting device 20 and a light-emitting cover, and in order to accommodate the components, the thickness required for the position corresponding to the light outlet 14 on the handle shell 10 is generally greater than the remaining parts, and by arranging the light outlet 14 on the protruding boss 1312 on the peripheral side portion 13, sufficient space can be provided for accommodating and arranging the components, and at the same time, it is beneficial to reduce the volume of the skin care device to make it more convenient to hold; in addition, the light outlet 14 serves as the main working window of the skin care device, and the protruding design of the light outlet 14 on the peripheral side portion 13 can facilitate the light-transmitting skin-contacting part 30 at the light outlet 14 to contact the skin, which is beneficial for the user to slide and use, and it is easy for the user to identify the main working window when using it, thereby achieving accurate control.

[0071] Considering that if the height of the protrusion is too high, the position height of the cooling component is also higher, which is not conducive to the heat conduction and heat dissipation of the heat dissipation copper tube, and the higher the height of the boss is, the higher the height of the structure that needs to be isolated from the side is, which is not conducive to preventing light leakage from the side. In addition, the height of the light-transmitting skin-approaching part is generally less than 2mm, and the cooling component can dissipate heat through the light-transmitting skin-approaching part. If the protruding height of the boss is too high, it is not conducive to the heat dissipation of the light-transmitting skin-approaching part. Therefore, the protruding height of the boss 1312 can be controlled within 0.2mm~15mm, such as 0.2mm, 0.5mm, 1mm, 1.2mm, 1.5mm, 2mm, 3mm, 5mm, 7mm, 8mm, etc. mm, 10mm, 12mm, 15mm, etc., or the distance between the contact surface 1313 and the first surface 1311 is controlled within 0.2mm to 15mm, such as 0.5mm, 1mm, 1.2mm, 2mm, 4mm, 4mm, 7mm, 9mm, 11mm, 12mm, 13mm, etc. By controlling the protruding height of the boss within the above range, it is beneficial to the heat dissipation of the protrusion and prevention of light leakage from the side, and at the same time, it can avoid the lamp tube 21 being placed on the protrusion, which is not conducive to heat dissipation; and the protruding design allows the light-transmitting skin-contacting part to protrude from the side and contact the skin, which is convenient for close contact with the skin and accurate control during use.

[0072] In addition, the light outlet 14 is the main working window of the skin care device. Its area (i.e., the light outlet area) affects the skin care efficiency and the degree of skin care refinement that can be achieved. If the area of the light outlet 14 is too small, the skin care efficiency is low. If the area of the light outlet 14 is too large, it is difficult to achieve refined operation. In this regard, the area of the light outlet 14 can be controlled to be greater than or equal to 5cm 2 and less than or equal to 8cm2 , such as the area of the light outlet 14 can be controlled to 5cm 2 , 5.5cm 2 , 6cm 2 , 7cm 2 , 7.5cm 2 , 8cm 2 Etc., without affecting delicate operations, providing a large window light output area, improving skin care efficiency and saving skin care time.

[0073] See also Figure 1 and Figure 2 In some embodiments, the peripheral side portion 13 is provided with a contact surface 1313 for contacting the skin, and the contact surface 1313 is formed with a contact detection portion 1313a, a light detection portion 1313b and a light outlet 14, and the translucent skin-contacting member 30 is installed at the light outlet 14; the contact detection portion 1313a and the light detection portion 1313b are distributed on the periphery of the light outlet 14; the skin care device also includes a contact detection device and a light detection device 40, the contact detection device is arranged in the accommodating cavity 15 and is arranged opposite to the contact detection portion 1313a, and the contact detection device is used to detect the contact state between the contact surface 1313 and the skin; the light detection device 40 is arranged in the accommodating cavity 15 and is arranged opposite to the light detection portion 1313b, and the light detection device 40 is used to perform optical detection on the skin.

[0074] By forming a contact detection part 1313a, a light detection part 1313b and a light outlet 14 on the contact surface 1313, when the device is in use, the light-emitting device 20 in the handle housing 10 emits light through the translucent skin-contacting part 30 at the light outlet 14 to care for the skin, and a contact detection device is provided for detecting the contact state between the contact surface 1313 and the skin through the contact detection part 1313a, and a light detection device 40 is provided for performing optical detection of the skin through the light detection part 1313b, so that the skin care device has both skin care function and skin contact detection function and optical detection function, which can realize skin contact and movement detection of the skin care device, and is conducive to light control. In addition, since the contact detection part 1313a and the light detection part 1313b are respectively located on the periphery of the light outlet 14, the contact detection device is distributed correspondingly along the contact detection part 1313a. In this way, the limited space of the detection surface can be utilized to reasonably distribute the detection areas of the contact detection device and the light detection device 40. The combined use of the contact detection device and the light detection device 40 can improve the accuracy of contact detection, thereby helping to improve the skin care effect of the skin care device.

[0075] Specifically, contact surface 1313 includes a first edge 1313c, a second edge 1313d, a third edge 1313e, and a fourth edge 1313f. First edge 1313c and third edge 1313e are spaced apart and opposed to each other, while second edge 1313d and fourth edge 1313f are spaced apart and opposed to each other. The lengths of first edge 1313c and third edge 1313e are both greater than the length of second edge 1313d, and greater than the length of fourth edge 1313f. That is, first edge 1313c and third edge 1313e are long edges, while second edge 1313d and fourth edge 1313f are short edges. First edge 1313c, second edge 1313d, third edge 1313e, and fourth edge 1313f may be rounded to enhance the comfort of contact between contact surface 1313 and skin. The first edge 1313c and the third edge 1313e may be specifically extended along the length direction of the handle housing 10 to fully utilize the side space of the handle housing 10 in the length direction.

[0076] The light detection portion 1313b is extended along the length direction of the first edge 1313c and is located between the light outlet 14 and the first edge 1313c or between the light outlet 14 and the third edge 1313e.

[0077] When a user controls the movement of the skin care device, the probability of moving along the first edge 1313c or the third edge 1313e is greater than the probability of moving along the second edge 1313d or the fourth edge 1313f. Therefore, by positioning the light detection unit 1313b between the light outlet 14 and the first edge 1313c or between the light outlet 14 and the third edge 1313e, the light detection unit 1313b remains within the skin area during movement of the skin care device, facilitating detection by the light detection device 40 and improving detection accuracy.

[0078] The light detection device 40 includes a movement detection sensor 41, which is arranged in the accommodating cavity 15 of the handle housing 10 and is arranged opposite to the light detection part 1313b. The movement detection sensor 41 is used to detect the movement information of the light detection part 1313b relative to the skin through the light detection part 1313b.

[0079] In some embodiments, the motion detection sensor 41 can detect the movement speed, changes in different positions, different pressing postures and other states of the skin care device, and then transmit the signal to the controller. If it is found that the skin care device stops or slides very slowly, which may burn the user, the controller will immediately stop the light emission output of the light-emitting device 20 to avoid burning the user's skin; when it is detected that the skin care device is moving normally again, it will immediately resume normal output to ensure the user's usage experience.

[0080] The motion detection sensor 41 is centrally disposed relative to the first edge 1313c along the length direction of the first edge 1313c; or, the motion detection sensor 41 is centrally disposed relative to the third edge 1313e along the length direction of the third edge 1313e.

[0081] In some embodiments, the motion detection sensor 41 is disposed near the center of the first edge 1313c or the third edge 1313e, so that when the contact surface 1313 moves relative to the skin, the motion detection sensor 41 is always in contact with the skin area, further improving the accuracy of motion detection.

[0082] In some embodiments, the light detection device 40 also includes a color sensor 42, which is disposed in the accommodating cavity 15 of the handle housing 10 and is arranged opposite to the light detection portion 1313b, and the color sensor 42 is disposed between the second edge 1313d and the movement detection sensor 41 along the length direction of the first edge 1313c. The color sensor 42 is used to detect the color information of the skin through the light detection portion 1313b.

[0083] Since the length of hair and the density of hair follicles are uneven, the reflected light of the skin is also uneven. Therefore, the color sensor 42 can detect comprehensive parameters including the color brightness and color type of the skin based on the reflected light of the skin, and finally reflect the skin information and hair information about the skin to be tested.

[0084] Color sensor 42 may include, but is not limited to, an RGB sensor. It is used to receive reflected light from the skin of the area being cared for, perform spectral analysis on the reflected light, determine the skin color value of the area being cared for, and transmit the skin color value to the controller. The controller then controls the intensity of light emitted by light-emitting device 20 based on the skin color value to provide care for users with different skin tones.

[0085] Since the skin color of different users is different, users with darker skin will absorb more heat when using light of the same heat for skin care, causing skin burns. The color sensor 42 is used to detect the skin color of the skin of the care area, and the light-emitting device 20 of the skin care device is controlled to emit light of different heat intensities to perform skin care on the user according to the detection results, thereby achieving the purpose of providing targeted care for the care areas with different skin colors.

[0086] In some embodiments, the light detection device 40 may further include a distance sensor 43, which is disposed in the accommodating cavity 15 of the handle housing 10 and is arranged opposite to the light detection portion 1313b, and the distance sensor 43 is disposed between the second edge 1313d and the movement detection sensor 41 along the length direction of the first edge 1313c. The distance sensor 43 is used to detect the distance information of the nursing working part relative to the skin through the light detection portion 1313b.

[0087] The distance sensor 43 may be an infrared distance measuring sensor or a laser distance measuring sensor, etc., which determines the distance between the contact surface 1313 of the skin care device and the skin by emitting light and detecting the reflection of the light.

[0088] In some embodiments, a distance sensor 43 can be connected to a controller to detect the distance between the contact surface 1313 and the skin. Specifically, if the distance between the contact surface 1313 and the skin is less than a preset value, the controller turns the skin care device on; if the distance between the contact surface 1313 and the skin is greater than the preset value, the controller turns the skin care device off. This allows the skin care device to automatically turn on and off, reducing power consumption.

[0089] In some embodiments, the light detection portion 1313b is a first through-hole extending through the contact surface 1313. The skin care device further includes a light guide 44 connected to the handle housing 10 and covering the first through-hole. Light emitted by the light detection device 40 during operation is emitted through the light guide 44 and irradiated onto the skin. The light guide 44 guides the light, making the emitted light more uniform. Furthermore, the light guide 44 prevents impurities such as gel and dust from entering the skin care device, protecting the light detection device 40 from damage.

[0090] In addition, the skin care device may further include a display portion 45, which may be specifically disposed on the side of the peripheral side portion 13 facing away from the light outlet 14; and / or, the peripheral side portion 13 may further include a fourth side portion 134 disposed opposite the third side portion 133 and connecting the first side portion 131 and the second side portion 132. The skin care device may further include a button disposed on the third side portion 133 or the fourth side portion 134. The provision of the display portion 45, and its placement on the side of the peripheral side portion 13 facing away from the light outlet 14, allows the user to easily understand information such as the skin care condition and the operating status of the skin care device during use. The light outlet 14 of the skin care device may be disposed on the first side portion 131 or the second side portion 132. By arranging the button on the side of the handle housing adjacent to the side where the light outlet is located, user operation may be facilitated.

[0091] In one embodiment, the skin care device is a hair removal device, and the light-emitting device 20 is a device used for hair removal. For example, the light-emitting device 20 can be a device that emits pulsed light or laser light. The pulsed light or laser light emitted by the light-emitting device 20 irradiates the hair follicles on the user's skin to achieve hair removal. In specific applications, as an alternative embodiment, the skin care device can also be a beauty device.

[0092] A light emitting device 20 is disposed within the accommodating cavity 15 of the handle housing 10. The light emitting device 20 is configured to emit light of a predetermined wavelength toward the light outlet 14. The light passes through the light outlet 14 and acts on the skin to achieve skin care. In actual production, the wavelength of light required to achieve the desired skin care needs can be determined based on skin care requirements, and a light emitting device 20 capable of emitting light of a specific wavelength (e.g., red light, infrared light, or other wavelengths) can be selected.

[0093] The light emitting device 20 can be a lamp tube 21 or other forms of light emitting device 20. Based on the location of the light emitting device 20 (specifically, it is located in the accommodating cavity 15 of the handle housing 10) and the light emission method of the device (side light emission), the lamp tube 21 can be used as the light emitting device 20 to facilitate structural integration with the accommodating structure handle housing 10, while at the same time achieving large-area light emission with the light emission method.

[0094] The number of lamps 21 in the light-emitting device 20 can be designed according to skin care requirements and can be one, two, three, or more. In some embodiments, the light-emitting device 20 includes at least two lamps 21, and each lamp 21 is arranged side by side in the accommodating cavity 15 of the handle housing 10 to emit light toward the light outlet 14. By adopting a design with multiple lamps 21, the light-emitting surface area and light intensity can be increased, improving skin care efficiency, and being suitable for skin care that requires high-intensity light, such as hair removal; each lamp 21 is arranged side by side in the accommodating cavity 15 of the handle housing 10, which helps to improve the regularity of the structural arrangement within the handle housing 10.

[0095] For example, refer to Figures 4 to 6 The light emitting device 20 includes two lamp tubes 21, which are spaced apart and arranged side by side in the receiving cavity 15 of the handle housing 10. This can expand the light output area and ensure light output efficiency. At the same time, the light emitting device 20 is not too large, and the volume of the handle housing 10 does not need to be increased too much, thereby facilitating handholding. Of course, the number of lamp tubes 21 in the light emitting device 20 can also be other multiples.

[0096] In order to make the light emitting surface of the lamp tube 21 more toward the light outlet 14 and make full use of the light emitting of the lamp tube 21, in some embodiments, the handle housing 10 has a first side portion 131, and a third side portion 133 and a fourth side portion 134 respectively provided on opposite sides of the first side portion 131; the first side portion 131, the third side portion 133 and the fourth side portion 134 are all extended along the length direction of the handle housing 10, the first side portion 131 connects the third side portion 133 and the fourth side portion 134, and the light outlet 1 4 is provided on the first side portion 131; the spacing arrangement direction of at least two lamp tubes 21 is along the third side portion 133 toward the fourth side portion 134. This can reduce or even avoid the problem that one lamp tube in the light-emitting device 20 is arranged side by side along the side of another lamp tube away from the light outlet, resulting in the lamp tube near the light outlet 14 blocking the rear lamp tube from emitting light toward the light outlet 14, thereby affecting the light output. Therefore, the light output intensity can be guaranteed, the light output efficiency of the light-emitting device 20 is improved, and light output over a large area is achieved, thereby improving the skin care effect.

[0097] The light-emitting device 20 generates heat during operation, causing the device temperature to rise, wherein the spacing of the lamp tubes 21 not only affects the device temperature, but also affects the light output intensity and skin care effect. Specifically, if the center spacing between adjacent lamp tubes 21 is too close, it is easy for the temperature of the lamp tube 21 to be too high, and it is not conducive to the formation of large-area light output; and if the center spacing between adjacent lamp tubes 21 is too large, the problem of uneven local light output intensity is easy to occur, wherein the local light energy is too large, which is easy to damage the skin, and the local light energy is too small, it cannot play a skin care role. To this end, in some embodiments, the center spacing between two adjacent lamp tubes 21 in the light-emitting device 20 is controlled to be greater than or equal to 5.3mm and less than or equal to 20mm, such as 5.5mm, 6mm, 8mm, 10mm, 13mm, 15mm, 18mm, 20mm, etc., to avoid excessive temperature, while helping to ensure light output intensity and skin care effect.

[0098] In addition, the outer diameter of the lamp tube 21 can be controlled within 4.3 mm ± 0.5 mm, thereby ensuring the luminous intensity while controlling the structural dimensions to reduce the size of the device and facilitate handheld operation.

[0099] In order to make full use of the light emitted by the light-emitting device 20 and make the light emitted toward the light outlet 14, the skin care device may further include a reflector 22. The reflector 22 is arranged in the accommodating cavity 15 of the handle housing 10, and the reflector 22 is arranged on the side of the light-emitting device 20 facing away from the light outlet 14. Therefore, the light emitted by the light-emitting device 20 to the reflector 22 can be reflected to the light outlet 14 through the reflective effect of the reflector 22, thereby improving the light utilization rate.

[0100] The reflector 22 is positioned near the light-emitting device 20 to reflect light emitted by the light-emitting device 20 toward the light outlet 14. However, the distance between the reflector 22 and the light-emitting device 20 affects the reflective efficiency and device performance. Specifically, if the distance between the reflector 22 and the light-emitting device 20 is too small, the reflector 22 is easily damaged by the light emitted by the light-emitting device 20. If the distance between the reflector 22 and the light-emitting device 20 is too large, the reflective efficiency is low and energy loss is large. To address this issue, a distance between the reflector 22 and the light-emitting device 20 of greater than or equal to 2 mm and less than or equal to 20 mm can be set. By controlling the distance between the reflector 22 and the light-emitting device 20 within this range, effective reflection can be achieved, energy loss can be reduced, and safety can be ensured. This avoids the situation where the reflector 22 is damaged by the light energy emitted by the light-emitting device 20 due to the distance being too small. For example, the distance between the reflector 22 and the light-emitting device 20 can be 2 mm, 5 mm, 8 mm, 10 mm, 15 mm, 18 mm, 20 mm, etc.

[0101] The light emitted by the light emitting device 20 hits the reflector 22, which causes the temperature of the reflector 22 to rise. Figure 5 In this embodiment, a first heat dissipation fin 221 is provided on the outer surface of the reflector 22 facing away from the light emitting device 20. Thus, the first heat dissipation fin 221 is provided to facilitate heat dissipation of the reflector 22. Of course, in some embodiments, the first heat dissipation fin 221 may be omitted.

[0102] In addition, in some embodiments, the length direction of the light emitting device 20 can be designed to be consistent with the length direction of the handle housing 10. By designing the light emitting device 20 and the handle housing 10 to be consistent in length, and coordinating the light outlet 14 to be located on the side portion 13 of the handle housing 10, which has a surface area larger than the bottom 12 and top 11, the side area of the handle housing 10 can be fully utilized to expand the light output surface area. On the other hand, the light output of the light emitting device 20 can be fully utilized to improve the light output efficiency, and the device can be reduced in size, making it more convenient to hold.

[0103] Reference Figures 4 to 6 In this embodiment, the light-emitting device 20 includes two lamp tubes 21 arranged side by side at intervals. The two lamp tubes 21 are arranged side by side at intervals along the direction from the second side 132 of the handle shell 10 toward the third side 133, and the length direction of the two lamp tubes 21 is consistent with the length direction of the handle shell 10.

[0104] A large amount of heat will be generated during the operation of the skin care device. If the heat cannot be effectively dissipated, the performance of the device may be affected. Furthermore, in order to achieve heat dissipation, the skin care device may further include a heat dissipation device 50. The heat dissipation device 50 is arranged in the accommodating cavity 15 of the handle shell 10, and the heat dissipation device 50 is at least used to dissipate heat to the light-emitting device 20 to avoid the light-emitting device 20 from emitting light and causing the device temperature to be too high, thereby affecting the performance.

[0105] In order to improve the heat dissipation effect of the heat dissipation device 50 on the light-emitting device 20, in some embodiments, the handle housing 10 is formed with a first air inlet 16 and a first air outlet 17, and the light-emitting device 20 is arranged between the heat dissipation device 50 and the first air outlet 17 along the length direction of the handle housing 10, so that the heat dissipation device 50 can directly blow heat to the light-emitting device 20 to improve the heat dissipation effect. In particular, when the light-emitting device 20 is composed of multiple lamp tubes 21, the heat dissipation effect is improved by arranging the light-emitting device 20 between the heat dissipation device 50 and the first air outlet 17, which can help ensure the normal operation of the multiple lamp tubes 21 and achieve large-area light output.

[0106] In some embodiments, the skin care device may further include a light shield 23 disposed between the first air outlet 17 and the light emitting device 20. The light shield 23 disposed between the light emitting device 20 and the first air outlet 17 prevents light emitted by the light emitting device 20 from escaping from the first air outlet 17. Furthermore, the light shield 23 and the reflector 22 are not integrally formed, which facilitates heat dissipation, allowing wind to flow from the light shield 23 and remove heat generated by the light emitting device 20.

[0107] The light blocking member 23 is mainly used to prevent light leakage. In some embodiments, the light blocking member 23 may be a reflective member, which can reflect the light irradiated by the light-emitting device 20 to the light outlet 14, thereby further effectively utilizing the light emitted by the light-emitting device 20 and improving the light output efficiency.

[0108] In addition to the light of specific wavelengths that can be used for skin care, the light emitted by the light emitting device 20 may also contain light that is harmful to the skin and / or light of other wavelengths that cannot play a role in skin care. To this end, the skin care device may further include a filter 24 for filtering out light that is useless for skin care from the light emitted by the light emitting device 20 and directed toward the light outlet 14, so that light of specific wavelengths passes through the filter 24 and is emitted through the light-transmitting skin-applying member 30 to act on the skin. The filter 24 is specifically arranged in the accommodating cavity 15 of the handle housing 10, and the filter 24 is arranged between the light emitting device 20 and the light-transmitting skin-applying member 30. Then, when in use, the light emitted by the light emitting device 20 passes through the filter 24 and the light-transmitting skin-applying member 30 in sequence and then exits the handle housing 10. The filter 24 can filter out light that may cause damage to the skin and / or other light that cannot play a role in skin care, thereby improving the safety and reliability of the skin care device.

[0109] For example, if the light emitting device 20 uses an intense pulsed light source, the light it emits includes both ultraviolet and visible light. Ultraviolet light can easily damage the skin, so the ultraviolet light can be filtered out by the filter 24. Specifically, the filter 24 can be designed to have a spacing greater than 0 mm and less than or equal to 5 mm between the light emitting device 20 to improve the filter's filtration efficiency and effectively filter out unwanted light. For example, the spacing between the filter 24 and the light emitting device 20 can be 0.5 mm, 1 mm, 1.5 mm, 2 mm, 3 mm, 3.5 mm, 4 mm, 5 mm, etc.

[0110] In addition, the distance between the filter 24 and the light-transmitting skin-applying member 30 can be designed to be greater than 0 mm and less than or equal to 2 mm. By controlling the distance between the filter 24 and the light-transmitting skin-applying member 30 within the above range, the light-transmitting skin-applying member 30 is relatively close to the light-emitting device 20, which facilitates the conduction of heat emitted by the light-emitting device 20 to the light-transmitting skin-applying member 30, and then conducts the heat away through the light-transmitting skin-applying member 30 to achieve sufficient heat dissipation. For example, the distance between the filter 24 and the light-transmitting skin-applying member 30 can be 0.5 mm, 1 mm, 1.5 mm, 1.8 mm, 2 mm, etc. In addition, the distance between the filter 24 and the light-emitting device 20 can be controlled to be greater than the distance between the filter 24 and the light-transmitting skin-applying member 30. The material of the filter 24 can be optical peeling or acrylic.

[0111] The light emitted by the light-emitting device 20 is emitted through the translucent skin-adhering part 30 arranged at the light outlet 14 and acts on the skin. The translucent skin-adhering part 30 is an active component of the skin care device that is in direct contact with the skin when in use. It is suitable for contact with the skin and will not block the light emitted by the light-emitting device 20. The light can be emitted through the translucent skin-adhering part 30.

[0112] The light energy density of the light-transmitting skin-applying member 30 will also affect the skin care effect. If the light energy density is too low, the skin care effect cannot be achieved, and if the energy density is too high, it is easy to damage the skin. To this end, the light energy emitted by the light-emitting device 20 after passing through the light-transmitting skin-applying member 30 can be controlled to be 1.96 J / cm 2 ~5.88J / cm 2 For example, the light emitted by the light emitting device 20 can be controlled to have an output energy of 1.96 J / cm after passing through the light-transmitting skin-applying member 30. 2 , 2J / cm 2 , 2.5J / cm 2 , 3J / cm 2 , 3.5J / cm 2 , 4J / cm 2 , 5.88J / cm 2 .

[0113] The light-transmitting skin-applied component 30 can be made of a transparent material to facilitate the transmission of light emitted by the light-emitting device 20. Specifically, transparent polymer materials such as PC and transparent ABS, or transparent inorganic materials such as glass, sapphire, ruby, and diamond can be used for the light-transmitting skin-applied component 30. Sapphire is preferably used for the light-transmitting skin-applied component 30 because of its high light transmittance, which reduces energy attenuation and improves light extraction efficiency. Furthermore, sapphire's excellent thermal conductivity enhances the cooling effect of the light-transmitting skin-applied component 30.

[0114] In some embodiments, the handle housing 10 is formed with a first air inlet 16 and a first air outlet 17. The light-emitting device 20 is disposed between the heat dissipation device 50 and the first air outlet 17 along the length of the handle housing 10. The first air inlet 16 can be specifically formed on the peripheral side portion 13. By configuring the first air inlet 16 on the peripheral side portion 13, air can be introduced from the side, which is conducive to configuring a large-sized air inlet and increasing the amount of flowing air entering the interior of the device, thereby improving the heat dissipation effect, ensuring the normal operation of the light-emitting device 20, and achieving light output over a large area.

[0115] Furthermore, the first air inlet 16 can be designed to be arranged on the same side as the light outlet 14, which can configure a large air inlet on the side of a large area, thereby facilitating the realization of large-area air intake while shortening the distance between the air inlet, the heat dissipation device 50 and the light outlet 14, which is beneficial to effectively dissipate heat for the light-emitting device 20, improve the heat dissipation effect, and ensure large-area light output.

[0116] The handle housing 10 may also be provided with a second air inlet 18, which is formed at the bottom 12 of the handle housing 10. Providing the second air inlet 18 at the bottom 12 of the handle housing 10 allows air entering the second air inlet 18 at the bottom 12 to take away heat from components at the bottom 12, preventing overheating of the components from affecting light output, while facilitating handheld use.

[0117] The first air outlet 17 on the handle shell 10 can be formed at the top 11 of the handle shell 10. By setting the first air outlet 17 at the top 11 of the handle shell 10, the light-emitting device 20 is set between the heat dissipation device 50 and the first air outlet 17 along the length direction of the handle shell 10. The heat dissipation device 50 can directly blow heat to the light-emitting device 20 to improve the heat dissipation effect; and the first air outlet 17 is not easily blocked during operation, which is conducive to the discharge of hot air and can prevent the air from being blocked and returning to the inside of the handle shell 10. The discharged hot air is not directed towards the user, which can improve the user experience; in addition, when the light outlet 14 is set on the first side portion 131 along the length direction of the handle shell 10 close to the end face of the top 11, the distance between the first air outlet 17 and the light outlet 14 is shortened, which is more conducive to heat dissipation and ensuring the normal operation of the light-emitting device 20.

[0118] In some embodiments, the first air outlet 17 is formed on the peripheral side portion 13 of the handle housing 10, and the distance between the first air outlet 17 and the top 11 is smaller than the distance between the first air outlet 17 and the bottom 12, so that the air outlet is close to the light-emitting device, which can facilitate heat dissipation of the light-emitting device. One or more of the first air inlet 16, the second air inlet 18, and the first air outlet 17 on the handle housing 10 can be constructed by forming a hollow structure on the handle housing 10 to construct the corresponding air outlet. The hollow structure of the air outlet can reduce the entry of external dust or other pollutants into the interior of the handle housing 10 through the air outlet, ensuring the cleanliness of the interior of the device. A dustproof net can also be set at one or more of the first air inlet 16, the second air inlet 18, and the first air outlet 17 to prevent pollutants from entering. In this embodiment, the first air inlet 16 and the first air outlet 17 are hollow structures, and a dustproof net 19 is set at the first air inlet 16 and the first air outlet 17. The dustproof net 19 is set in the accommodating cavity 15 of the handle housing 10. By setting the dustproof nets 19 at the first air inlet 16 and the first air outlet 17, external pollutants can be prevented from entering. In addition, the dustproof net 19 set at the first air outlet 17 can also prevent the blown hot air from flowing back into the handle housing 10.

[0119] The heat dissipation device 50 is mainly used to dissipate heat for the light-emitting device 20. The heat dissipation device may specifically include a fan 51. The fan 51 has a third air inlet 511 and a second air outlet 512. The third air inlet 511 faces the first air inlet 16 on the handle housing 10, and the second air outlet 512 faces the first air outlet 17 on the handle housing 10. The light-emitting device 20 can be arranged between the second air outlet 512 and the first air outlet 17 along the length direction of the handle housing 10. Through the above structural setting, a gas flow channel can be formed inside the device during the operation of the device. Specifically, the air from the first air inlet 16 enters the fan 51 through the third air inlet 511, flows out from the second air outlet 512, passes through the light-emitting device 20, takes away the heat of the light-emitting device 20, and is discharged from the first air outlet 17, thereby realizing the heat dissipation of the light-emitting device 20; and the air outlet space position of the fan 51 is horizontal with the light-emitting device 20, which can directly blow heat to the light-emitting device 20 to avoid the wind being blocked by the transparent skin-attached part 30, thereby ensuring the normal operation of the light-emitting device 20 and reserving accommodation space for the arrangement of other components.

[0120] In this embodiment, an air guide heat sink 54 is further provided between the second air outlet 512 and the light-emitting device 20. When in use, the air outlet of the fan 51 can be guided by the air guide heat sink 54 and blown directly toward the light-emitting device 20, taking away the heat of the light-emitting device 20, thereby achieving effective heat dissipation of the light-emitting device 20 and improving the heat dissipation efficiency.

[0121] In addition, in this embodiment, the skin care device also includes a semiconductor refrigeration plate 60, which is arranged in the accommodating cavity 15 of the handle shell 10, and the cold end of the semiconductor refrigeration plate 60 is in contact with the light-transmitting skin-adhesive part 30. By setting the semiconductor refrigeration plate 60 in contact with the light-transmitting skin-adhesive part 30 for cooling, the cooled light-transmitting skin-adhesive part 30 can use low temperature to perform cold compress on the care area, effectively restraining the problem of the skin of the care area being too hot due to light exposure.

[0122] In order to further improve the heat dissipation effect of the skin care equipment, the heat dissipation device 50 may also include a heat dissipation copper tube 52, which is arranged in the accommodating cavity 15 of the handle shell 10, and one end of the heat dissipation copper tube 52 is attached to the hot end of the semiconductor refrigeration plate 60, and the other end of the heat dissipation copper tube 52 is arranged between the third air inlet 511 and the first air inlet 16; the attached section of the heat dissipation copper tube 52 with the semiconductor refrigeration plate 60 is a flat structure, and / or the section of the heat dissipation copper tube 52 located between the third air inlet 511 and the first air inlet 16 is a flat structure. Among them, the fitting section of the heat dissipation copper tube 52 and the semiconductor refrigeration plate 60 is designed to be a flat structure, which can expand the contact area with the semiconductor refrigeration plate 60 and improve the heat dissipation effect. At the same time, it can reduce the side space occupied by the heat dissipation copper tube 52 to ensure a large area of light output; the end of the heat dissipation copper tube 52 away from the semiconductor refrigeration plate 60 is arranged between the third air inlet 511 and the first air inlet 16. During operation, the heat of the semiconductor refrigeration plate 60 can be conducted to the heat dissipation copper tube 52, and then the heat is taken away by the incoming air from the first air inlet 16 when passing through the heat dissipation copper tube 52. The heat dissipation copper tube 52 of this section is designed to be a flat structure, which can increase its contact area with the incoming air, which is beneficial to heat dissipation and can reduce the thickness space occupied, making it convenient for handheld use.

[0123] In this embodiment, the heat dissipation device 50 further includes a second heat dissipation fin 53, which is disposed within the accommodating cavity 15 of the handle housing 10 and between the third air inlet 511 and the first air inlet 16. The end of the heat dissipation copper tube 52 away from the semiconductor refrigeration plate 60 is thermally connected to the second heat dissipation fin 53. The end of the heat dissipation copper tube 52 away from the semiconductor refrigeration plate 60 can be arranged to contact the second heat dissipation fin 53 to achieve a thermal connection, or can be designed to penetrate and connect the second heat dissipation fin 53. By providing a thermal connection between the second heat dissipation fin 53 and the heat dissipation copper tube 52, and the second heat dissipation fin 53 is disposed between the third air inlet 511 and the first air inlet 16, the heat of the heat dissipation copper tube 52 can be conducted to the second heat dissipation fin 53, and the air entering from the first air inlet 16 can pass through the second heat dissipation fin 53 to carry away the heat, thereby improving the heat dissipation effect of the heat dissipation copper tube 52.

[0124] The second heat sink fins 53 can be further designed to cover the first air inlet 16, and the dust screen 19 is provided between the first air inlet and the second heat sink fins 53. This ensures that the incoming air passes through the second heat sink fins 53 to the greatest extent possible, quickly removing the heat from the second heat sink fins 53, effectively dissipating the heat from the heat dissipation copper tube 52, ensuring a cooling effect for the large-area light outlet 14, achieving a large-area light output while avoiding skin damage. Of course, in some embodiments, the second heat sink fins 53 can also be omitted.

[0125] In addition, the skin care device may also include a circuit board 70. The circuit board 70 is disposed within the accommodating cavity 15 of the handle housing 10 and is located on the side of the light-emitting device 20 facing away from the light outlet 14. The circuit board 70 is electrically connected to the lamp 21. The circuit board 70 can serve as a controller, at least for controlling the on and off of the lamp 21. In addition, the circuit board 70 can also be electrically connected to the fan 51 and used to control the on and off of the fan 51. By disposing the circuit board 70 within the accommodating cavity 15 of the handle housing 10 and on the side of the light-emitting device 20 facing away from the light outlet 14, it is convenient to provide power to the electrical devices without affecting light emission and hand-holding.

[0126] In addition, the handle housing 10 may be provided with a power socket electrically connected to the circuit board 70, and the skin care device may further include a matching power cord that can be connected between the power socket of the handle housing 10 and a computer USB port to provide power, or a power adapter that is plugged into the power socket to convert AC power into DC power of a certain voltage. Of course, in some embodiments, a power supply device such as a power adapter may be provided separately from the skin care device. This can reduce the size of the skin care device for easier handholding and eliminate the need for heat dissipation of the power supply device such as the power adapter, thereby saving energy.

[0127] In addition, the present application also provides a skin care system, comprising a skin care device as described in any one of the above embodiments. The skin care system further comprises at least one of a charging assembly, a control device, a placement bracket, and a protective cover. The charging assembly is disposed outside the skin care device and electrically connected to the skin care device to power the skin care device. The control device is disposed within a receiving cavity of the skin care device or outside the skin care device and is in communication with the light-emitting device. The placement bracket is used to accommodate the skin care device. The protective cover is used to protect the light-emitting device of the skin care device.

[0128] Specifically, the charging component can be an energy box, a charging stand, a data cable plug and other devices, which can be used to charge the skin care device, control the energy output of the skin care device, etc.; the placement bracket can be a device used to stably place the charging device on a table or other surface, so that the skin care device can be stably placed on a table or other surface in a vertical, inclined or lying posture, and can separate the skin care device from the table to prevent the skin care device from coming into contact with water or dirt on the table.

[0129] The above embodiments of the present application are merely examples for the purpose of clearly illustrating the present application and are not intended to limit the implementation methods of the present application. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not possible to enumerate all implementation methods here. Any obvious variations or modifications arising from the technical solution of the present application are still within the scope of protection of the present application.
