[0059] To make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail with reference to the accompanying drawings.

[0060] The present application provides a skin care device, which is mainly used for caring the skin, and the skin can be the skin of face, hands or legs or other parts of the human body.

[0061] Referring to FIG. 1, and FIG. 3 to FIG. 6, the skin care device provided by an embodiment of the present application comprises a handle shell 10, a light emitting device 20 and a light-transmitting skin contact member 30. The handle shell 10 comprises a top portion 11, a bottom portion 12 and a peripheral portion 13 between the top portion 11 and the bottom portion 12, the peripheral portion 13 is connected with the top portion 11 and the bottom portion 12, and the peripheral portion 13 and the top portion 11 and the bottom portion 12 form a receiving cavity 15, the surface area of the peripheral portion 13 is greater than the surface area of the top portion 11, and / or the surface area of the peripheral portion 13 is greater than the surface area of the bottom portion 12, and the peripheral portion 13 is provided with a light outlet 14 which is in communication with the receiving cavity 15; the light emitting device 20 is arranged in the receiving cavity 15 and is arranged to emit light towards the light outlet 14; the light-transmitting skin contact member 30 is arranged at the light outlet 14 and is arranged to allow the light emitted by the light emitting device 20 to pass through.

[0062] In use, the light emitting device 20 arranged in the receiving cavity 15 of the handle shell 10 emits light of a specific wavelength, and the light passes through the light-transmitting skin contact member 30 arranged at the light outlet 14 and is emitted out of the handle shell 10 to act on the skin to achieve the purpose of skin care. Since the light outlet 14 of the skin care device is arranged on the peripheral portion 13 of the handle shell 10, the surface area of which is greater than the surface area of the bottom portion 12 and / or the surface area of the top portion 11, and the light emitting device 20 is arranged in the receiving cavity 15 of the handle shell 10 and emits light towards the light outlet 14, the skin care device can realize lateral light emission, can make full use of the side area of the handle shell 10, can increase the light emitting area of the skin care device, can achieve the effect of large-area light emission, and can improve the skin care efficiency, such as hair removal efficiency. In addition, the light emitting device 20 is arranged in the receiving cavity 15 of the handle shell 10, which can make full use of the space in the handle shell 10 to arrange a large-volume light emitting device 20, is beneficial to simplify the head of the skin care device, and can effectively avoid the problem of large head size and heavy head and light foot of the skin care device, thereby facilitating the user to hold and operate.

[0063] The handle shell 10 of the skin care device serves as the main external frame of the skin care device and is used to mount and protect various components of the skin care device. Specifically, the handle shell 10 comprises a top portion 11, a bottom portion 12 and a peripheral portion 13 between the top portion 11 and the bottom portion 12, the peripheral portion 13 is connected with the top portion 11 and the bottom portion 12, and the peripheral portion 13 and the top portion 11 and the bottom portion 12 form a receiving cavity 15, various components of the skin care device can be accommodated in the receiving cavity 15 of the handle shell 10 to be integrated as a whole. The handle shell 10 can also serve as a protective shell to protect the internal components. In specific use of the skin care device, the handle shell 10 generally serves as a hand-held portion, and the handle shell 10 can be designed in a columnar shape or other shape which is suitable for hand holding.

[0064] The light outlet 14 of the skin care device is located on the peripheral side 13 of the handle housing 10. Of course, in some embodiments, the light outlet 14 may also be located on other parts of the handle housing 10, such as the top 11 or the bottom 12.

[0065] In some embodiments, the peripheral side portion 13 includes a first side portion 131, a second side portion 132 disposed opposite to 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, smaller than the surface area of ​​the second side portion 132, larger than the surface area of ​​the top portion 11, and larger than the surface area of ​​the bottom portion 12. The light outlet 14 is disposed on the first side portion 131 or the second side portion 132. With the above structural configuration, the large area of ​​the handle housing 10 can be fully utilized to increase the light-emitting area of ​​lateral light emission, effectively achieving a large-area light emission effect. Of course, in some embodiments, the light outlet 14 can also be disposed on other sides of the peripheral side portion 13, which can also utilize the side of the handle housing 10 to a certain extent to increase the light-emitting area and achieve a large-area light emission effect.

[0066] In some embodiments, the distance between the light outlet 14 and the top 11 is less than the distance between the light outlet 14 and the bottom 12. With this structural arrangement, sufficient handholding area can be provided for the user to use the skin care device. The area where the light outlet 14 is located on the handle housing 10 serves as the working section, while the remaining sections serve as the handhold section. This facilitates handholding operation by the user and makes it easier to control the light-transmitting skin-adhesive part 30 at the light outlet 14 of the device to adhere to the skin for skin care.

[0067] To facilitate handheld operation and skin contact, 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 adhere to the skin during use, thus making it easier to hold and use.

[0068] In some embodiments, the peripheral side portion 13 may be designed to have a protruding boss 1312, and the light outlet 14 is disposed on the boss 1312. 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 light-emitting port 14 generally includes at least a light-transmitting skin-feeling element 30, a light-emitting device 20, and a light-emitting cover along its thickness direction (or light-emitting direction), the thickness required at the position corresponding to the light-emitting port 14 on the handle housing 10 is generally greater than the rest of the part in order to accommodate the components. Therefore, by setting the light-emitting port 14 on the protruding boss 1312 on the peripheral part 13, sufficient space can be provided for the arrangement of components, and it is also beneficial to reduce the size of the skin care device, making it easier to hold. In addition, as the main working window of the skin care device, the protruding design of the light-emitting port 14 on the peripheral part 13 facilitates the contact between the light-transmitting skin-feeling element 30 at the light-emitting port 14 and the skin, which is beneficial for the user to slide and use, and makes it easy for the user to clearly identify the main working window and achieve accurate operation.

[0069] Considering that if the protrusion is too high, the height of the cooling component will also be higher, which is not conducive to the heat conduction and dissipation of heat by the heat dissipation copper pipe. Furthermore, the higher the protrusion, the higher the height of the side light-blocking structure needs to be, which is not conducive to preventing light leakage from the sides. Additionally, the height of the light-transmitting skin-like component is generally less than 2mm, allowing the cooling component to dissipate heat through it. If the protrusion height is too high, it will hinder the heat dissipation of the light-transmitting skin-like component. Therefore, the protrusion height of the 1312 protrusion can be controlled between 0.2mm and 15mm, such as 0.2mm, 0.5mm, 1mm, 1.2mm, 1.5mm, 2mm, 3mm, 5mm, 7mm, and 8mm. The protrusion height can be controlled within the range of 0.2mm to 15mm, such as 0.5mm, 1mm, 1.2mm, 2mm, 3mm, 4mm, 7mm, 9mm, 11mm, 12mm, 13mm, etc. By controlling the protrusion height of the boss within the above range, it is beneficial to heat dissipation of the protrusion and prevent light leakage from the side. At the same time, it can avoid the lamp tube 21 being placed in the protrusion, which is not conducive to heat dissipation. In addition, the protrusion 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 operation during use.

[0070] Furthermore, the light outlet 14, as the main working window of the skin care device, significantly affects the efficiency and precision of skin care. If the light outlet 14 is too small, the skin care efficiency is low; if it is too large, precise operation becomes difficult. Therefore, the area of ​​the light outlet 14 can be controlled to be greater than or equal to 5 cm². 2And less than or equal to 8cm 2 For example, the area of ​​the light outlet 14 can be controlled to be 5cm². 2 5.5cm 2 6cm 2 7cm 2 7.5cm 2 8cm 2 This allows for precise operation while providing a large light-emitting area, improving skin care efficiency and saving skin care time.

[0071] Referring to Figures 1 and 2, in some embodiments, the peripheral portion 13 is provided with a contact surface 1313 for contacting the skin. The contact surface 1313 forms a contact detection part 1313a, a light detection part 1313b, and a light outlet 14. The light-transmitting skin-adhesive part 30 is installed in the light outlet 14. The contact detection part 1313a and the light detection part 1313b are distributed around 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 disposed in the receiving cavity 15 and is disposed opposite to the contact detection part 1313a. 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 disposed in the receiving cavity 15 and is disposed opposite to the light detection part 1313b. The light detection device 40 is used to perform optical detection on the skin.

[0072] By forming a contact detection section 1313a, a light detection section 1313b, and a light outlet 14 on the contact surface 1313, when the device is in use, the light-emitting device 20 inside the handle housing 10 emits light through the light-transmitting skin-contact piece 30 at the light outlet 14 to care for the skin. The contact detection device is set to detect the contact state between the contact surface 1313 and the skin through the contact detection section 1313a, and the light detection device 40 is set to perform optical detection on the skin through the light detection section 1313b. Thus, the skin care device has both skin care function, skin contact detection function, and optical detection function, which can realize skin contact and movement detection of the skin care device and facilitate light emission control. Furthermore, since the contact detection unit 1313a and the light detection unit 1313b are located on the periphery of the light outlet 14, and the contact detection devices are correspondingly distributed along the contact detection unit 1313a, the limited space of the detection surface can be utilized to rationally distribute the detection areas of the contact detection devices and the light detection devices 40. Moreover, the combined use of the contact detection devices and the light detection devices 40 can improve the accuracy of contact detection, thereby improving the skin care effect of the skin care device.

[0073] Specifically, the contact surface 1313 has a first edge 1313c, a second edge 1313d, a third edge 1313e, and a fourth edge 1313f. The first edge 1313c and the third edge 1313e are spaced apart and opposite to each other, and the second edge 1313d and the fourth edge 1313f are also spaced apart and opposite to each other. The lengths of the first edge 1313c and the third edge 1313e are both greater than the length of the second edge 1313d and the fourth edge 1313f, respectively. That is, the first edge 1313c and the third edge 1313e are long edges, and the second edge 1313d and the fourth edge 1313f are short edges. The first edge 1313c, the second edge 1313d, the third edge 1313e, and the fourth edge 1313f can be rounded to improve the comfort of the contact surface 1313 in contact with the skin. The first edge 1313c and the third edge 1313e can be specifically arranged to extend along the length direction of the handle housing 10 in order to make full use of the lateral space of the handle housing 10 in the length direction.

[0074] The light detection unit 1313b extends along the length direction of the first edge 1313c, and the light detection unit 1313b is located between the light outlet 14 and the first edge 1313c or between the light outlet 14 and the third edge 1313e.

[0075] When a user controls the movement of a skin care device, the probability of movement along the first edge 1313c and the third edge 1313e is greater than the probability of movement along the second edge 1313d and the fourth edge 1313f. Therefore, the light detection unit 1313b is positioned between the light outlet 14 and the first edge 1313c or between the light outlet 14 and the third edge 1313e, ensuring that the light detection unit 1313b remains within the skin area during the movement of the skin care device. This facilitates the detection function of the light detection device 40 and improves the accuracy of the detection.

[0076] The light detection device 40 includes a motion detection sensor 41, which is disposed in the receiving cavity 15 of the handle housing 10 and is disposed opposite to the light detection unit 1313b. The motion detection sensor 41 is used to detect the movement information of the light detection unit 1313b relative to the skin through the light detection unit 1313b.

[0077] In some embodiments, the motion detection sensor 41 can detect the movement speed of the skin care device, changes in position, different pressing postures, etc., and then transmit the signal to the controller. If the controller detects that the skin care device has stopped or the sliding speed is very slow, 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 the normal operation of the skin care device is detected again, the normal output will be restored immediately, thus ensuring the user's experience.

[0078] The motion detection sensor 41 is centered relative to the first edge 1313c along the length direction of the first edge 1313c; or, the motion detection sensor 41 is centered relative to the third edge 1313e along the length direction of the third edge 1313e.

[0079] In some embodiments, the motion detection sensor 41 is positioned near the center of the first edge 1313c or the third edge 1313e, such that the motion detection sensor 41 is always in contact with the skin area during the movement of the contact surface 1313 relative to the skin, thereby further improving the accuracy of motion detection.

[0080] In some embodiments, the light detection device 40 further includes a color sensor 42, which is disposed in the receiving cavity 15 of the handle housing 10 and is disposed opposite to the light detection unit 1313b. The color sensor 42 is disposed along the length direction of the first edge 1313c between the second edge 1313d and the motion detection sensor 41. The color sensor 42 is used to detect skin color information through the light detection unit 1313b.

[0081] Because the length of hair and the density of hair follicles are uneven, the reflected light from the skin is also uneven. Therefore, the color sensor 42 can detect comprehensive parameters including the skin's color brightness and color type based on the reflected light from the skin, and finally reflect the skin information and hair information of the skin to be tested.

[0082] The color sensor 42 may include, but is not limited to, an RGB sensor. The color sensor 42 is used to receive reflected light from the skin of the area to be treated, perform spectral analysis on the reflected light to obtain the skin color value of the skin of the area to be treated, and send the skin color value to the controller. The controller controls the intensity of the light emitted by the light-emitting device 20 based on the skin color value to provide treatment for users with different skin colors.

[0083] Since different users have different skin tones, users with darker skin tones will absorb more heat when using the same amount of heat light for skin care, which may cause their skin to be burned. The color sensor 42 detects the skin tone of the area to be cared for, and controls the light-emitting device 20 of the skin care device to emit light of different heat intensities to care for the user's skin, thus achieving the purpose of targeted care for areas with different skin tones.

[0084] In some embodiments, the light detection device 40 may further include a distance sensor 43, which is disposed in the receiving cavity 15 of the handle housing 10 and is disposed opposite to the light detection unit 1313b. The distance sensor 43 is disposed along the length direction of the first edge 1313c between the second edge 1313d and the motion detection sensor 41. The distance sensor 43 is used to detect the distance information between the care work part and the skin through the light detection unit 1313b.

[0085] The distance sensor 43 can be an infrared distance sensor or a laser distance 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.

[0086] 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, when the distance between the contact surface 1313 and the skin is less than a preset value, the controller controls the skin care device to be turned on; when the distance between the contact surface 1313 and the skin is greater than the preset value, the controller controls the skin care device to be turned off. This allows for automatic power-on and power-off of the skin care device, reducing power consumption.

[0087] In some embodiments, the light detection unit 1313b is a first through hole extending through the contact surface 1313; the skin care device also includes a light guide 44, which is connected to the handle housing 10 and covers the first through hole. Thus, the light emitted by the light detection device 40 during operation is emitted through the light guide 44 and irradiates the skin. The light guide 44 serves to guide light, making the emitted light more uniform. Simultaneously, 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.

[0088] In addition, the skin care device may also include a display unit 45, which may be specifically disposed on the side of the peripheral portion 13 opposite to the light outlet 14; and / or, the peripheral portion 13 may also include a fourth side portion 134 disposed opposite to the third side portion 133 and connecting the first side portion 131 and the second side portion 132. The skin care device also includes a button 71, which is disposed on the third side portion 133 or the fourth side portion 134. The placement of the display unit 45 on the side of the peripheral portion 13 opposite to the light outlet 14 facilitates user access to information such as skin care procedures and the operating status of the skin care device. The light outlet 14 of the skin care device may be located on the first side portion 131 or the second side portion 132. By placing the button 71 on the side of the handle housing adjacent to the side where the light outlet is located, user operation is facilitated.

[0089] In one implementation, the skin care device is a hair removal device, and the light-emitting device 20 is a device used for hair removal treatment of the skin. 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 of the user's skin to achieve hair removal. In specific applications, as an alternative implementation, the skin care device can also be a beauty device.

[0090] The housing 15 of the handle shell 10 is equipped with a light-emitting device 20. The light-emitting device 20 is used to emit light of a predetermined wavelength toward the light outlet 14. After passing through the light outlet 14, the light acts on the skin to achieve the purpose of skin care. Furthermore, in actual production, the wavelength of light required to achieve the corresponding skin care requirements can be determined according to the skin care requirements, thereby selecting a light-emitting device 20 that can emit light of a specific wavelength (such as red light, infrared light, or other wavelengths).

[0091] The light-emitting device 20 can be a lamp tube 21 or other forms of light-emitting device 20. Based on the position of the light-emitting device 20 (specifically located in the receiving cavity 15 of the handle housing 10) and the light emission method of the device (side light emission), a lamp tube 21 can be used as the light-emitting device 20 to facilitate structural integration with the receiving structure handle housing 10, and at the same time, to achieve large-area light emission in conjunction with the light emission method.

[0092] The number of lamps 21 in the light-emitting device 20 can be designed according to skincare requirements, and can be one, two, three, or other multiple. In some embodiments, the light-emitting device 20 includes at least two lamps 21, and each lamp 21 is arranged side by side at intervals within the receiving cavity 15 of the handle housing 10 to emit light towards the light outlet 14 respectively. By adopting a multi-lamp design, the light-emitting surface area and light intensity can be increased, improving skincare efficiency, and it is suitable for skincare treatments such as hair removal that require high-intensity light; the arrangement of each lamp 21 side by side at intervals within the receiving cavity 15 of the handle housing 10 helps to improve the regularity of the internal structural arrangement of the handle housing 10. Optionally, the distance between the multiple lamps and the light-transmitting skin-applying component is equal, which can make the light intensity of the lamps more uniform, improve the skincare effect, and avoid uneven light intensity that could damage the skin.

[0093] For example, referring to Figures 4 to 6, the light-emitting device 20 includes two lamps 21, which are arranged side-by-side with a gap between them within the receiving cavity 15 of the handle housing 10. This expands the light-emitting area and ensures light-emitting efficiency, while preventing the light-emitting device 20 from becoming too large, thus avoiding excessively increasing the size of the handle housing 10 and facilitating handheld operation. Of course, the number of lamps 21 in the light-emitting device 20 can also be multiple, such as three, four, or five.

[0094] To maximize the light-emitting surface of the lamp tube 21 facing the light outlet 14 and fully utilize its light output, 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 disposed 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 all extend along the length direction of the handle housing 10, and the first side portion 131 connects the third side portion 133 and the fourth side portion 134, and the light outlet 14... 4 is located on the first side 131; the spacing of at least two lamp tubes 21 is along the direction from the third side 133 toward the fourth side 134. This can reduce or even avoid the problem that if one lamp tube in the light-emitting device 20 is arranged side by side with another lamp tube away from the light outlet, the lamp tube near the light outlet 14 will block the light emitted by the lamp tube behind it from the light outlet 14, thus affecting the light output. This can ensure the light output intensity, improve the light output efficiency of the light-emitting device 20, facilitate the realization of large-area light output, and thus improve the skin care effect.

[0095] The light-emitting device 20 generates heat during operation, causing its temperature to rise. The spacing between the lamp tubes 21 not only affects the device temperature but also influences the light intensity and skincare effect. Specifically, if the center-to-center spacing between adjacent lamp tubes 21 is too close, the lamp tubes 21 are prone to overheating and are not conducive to forming a large area of ​​light emission; conversely, if the center-to-center spacing between adjacent lamp tubes 21 is too large, uneven light intensity in certain areas can occur. Excessive light energy in some areas can damage the skin, while insufficient light energy in others fails to provide a skincare effect. Therefore, in some embodiments, the center-to-center spacing between two adjacent lamp tubes 21 in the light-emitting device 20 is controlled to be greater than or equal to 5.3 mm and less than or equal to 20 mm, such as 5.5 mm, 6 mm, 8 mm, 10 mm, 13 mm, 15 mm, 18 mm, 20 mm, etc., to avoid overheating while ensuring light intensity and skincare effect.

[0096] In addition, the outer diameter of the lamp tube 21 can be controlled within 4.3mm ± 0.5mm, which controls the structural size while ensuring the luminous intensity, thereby reducing the size of the device and making it easier to operate by hand.

[0097] In order to make full use of the light emitted by the light-emitting device 20 and direct the light out toward the light outlet 14, the skin care device may also include a reflector 22. The reflector 22 is disposed in the receiving cavity 15 of the handle housing 10 and covers the side of the light-emitting device 20 that is away from the light outlet 14. Thus, 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.

[0098] The reflector 22 is positioned close to the light-emitting device 20 to reflect the light emitted by the light-emitting device 20 towards the light outlet 14. However, the distance between the reflector 22 and the light-emitting device 20 affects the reflection 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 is too large, the reflection efficiency is low, resulting in significant energy loss. To address this, a distance of greater than or equal to 2 mm and less than or equal to 20 mm can be set between the reflector 22 and the light-emitting device 20. By controlling the distance within this range, effective reflection can be achieved, energy loss can be reduced, and safety can be ensured, preventing the reflector 22 from being damaged by the light energy emitted by the light-emitting device 20 if the distance is 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.

[0099] The light emitted by the light-emitting device 20 will cause the reflector 22 to heat up when it hits the reflector 22. Referring to 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 can be omitted.

[0100] 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 direction, and with the light outlet 14 located on the peripheral side 13 of the handle housing 10 where the surface area of ​​the upper surface is larger than the surface area of ​​the bottom 12 and the top 11, the side area of ​​the handle housing 10 can be fully utilized to expand the light-emitting surface area. On the other hand, the light emission of the light-emitting device 20 can be fully utilized to improve the light emission efficiency, and the size of the device can be reduced, making it more convenient to hold.

[0101] Referring to 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 second side 132 of the handle housing 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 housing 10.

[0102] Skin care devices generate a lot of heat during operation. If the heat cannot be effectively dissipated, it may affect the performance of the device. Therefore, in order to achieve heat dissipation, the skin care device may also include a heat dissipation device 50. The heat dissipation device 50 is located in the receiving cavity 15 of the handle housing 10, and the heat dissipation device 50 is at least used to dissipate heat from the light-emitting device 20 to prevent the light-emitting device 20 from emitting light and causing the device temperature to be too high, thus affecting the performance.

[0103] 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. The light-emitting device 20 is disposed between the heat dissipation device 50 and the first air outlet 17 along the length direction of the handle housing 10. Thus, the heat dissipation device 50 can directly blow heat to the light-emitting device 20, thereby improving the heat dissipation effect. In particular, when the light-emitting device 20 is composed of multiple lamp tubes 21, by placing the light-emitting device 20 between the heat dissipation device 50 and the first air outlet 17, the heat dissipation effect is improved, which can help ensure the normal operation of the multiple lamp tubes 21 and achieve large-area light emission.

[0104] In some embodiments, the skin care device may further include a light-blocking element 23 disposed between the first air outlet 17 and the light-emitting device 20. By providing the light-blocking element 23 between the light-emitting device 20 and the first air outlet 17, light emitted by the light-emitting device 20 can be prevented from leaking out of the first air outlet 17; and the light-blocking element 23 and the reflector 22 are not integrally designed, which facilitates the flow of air from the direction of the light-blocking element 23 during the heat dissipation process to carry away the heat generated by the light-emitting device 20.

[0105] The light-blocking component 23 is mainly used to prevent light leakage. In some embodiments, the light-blocking component 23 can be a reflective component. The reflective component 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.

[0106] In addition to specific wavelengths of light suitable for skin care, the light emitted by the light-emitting device 20 may also contain harmful light and / or other wavelengths that do not provide skin care benefits. Therefore, the skin care device may include a filter 24 to filter out the light emitted by the light-emitting device 20 and directed towards the light outlet 14, allowing light of the specific wavelengths to pass through the filter 24 and then through the light-transmitting skin-contacting component 30 to act on the skin. Specifically, the filter 24 is located within the receiving cavity 15 of the handle housing 10, positioned between the light-emitting device 20 and the light-transmitting skin-contacting component 30. During use, the light emitted by the light-emitting device 20 passes sequentially through the filter 24 and the light-transmitting skin-contacting component 30 before exiting the handle housing 10. The filter 24 effectively filters out harmful and / or non-skin-contacting light, thereby improving the safety and reliability of the skin care device.

[0107] For example, if the light-emitting device 20 uses a strong pulsed light source, the emitted light includes ultraviolet and visible light. Ultraviolet light can easily damage the skin; therefore, it can be filtered out by the filter element 24. Specifically, a distance greater than 0 mm and less than or equal to 5 mm can be designed between the filter element 24 and the light-emitting device 20 to improve the filtering efficiency of the filter element 24 and fully filter out unwanted light. For example, the distance between the filter element 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.

[0108] Furthermore, a gap greater than 0 mm and less than or equal to 2 mm can be designed between the light filter 24 and the light-transmitting skin-like component 30. By controlling the gap between the light filter 24 and the light-transmitting skin-like component 30 within this range, the light-transmitting skin-like component 30 is closer to the light-emitting device 20, which facilitates the conduction of heat emitted by the light-emitting device 20 to the light-transmitting skin-like component 30, and then the heat is conducted away through the light-transmitting skin-like component 30 to achieve sufficient heat dissipation. For example, the gap between the light filter 24 and the light-transmitting skin-like component 30 can be 0.5 mm, 1 mm, 1.5 mm, 1.8 mm, 2 mm, etc. Additionally, the gap between the light filter 24 and the light-emitting device 20 can be controlled to be greater than the gap between the light filter 24 and the light-transmitting skin-like component 30. The material of the light filter 24 can be optically laminated or acrylic.

[0109] The light emitted by the light-emitting device 20 is emitted through the light-transmitting skin-adhesive part 30 provided at the light outlet 14 and acts on the skin. The light-transmitting skin-adhesive part 30 is a part that comes into direct contact with the skin when the skin care device is used. It is suitable for contact with the skin and does not block the light emitted by the light-emitting device 20. The light can be emitted through the light-transmitting skin-adhesive part 30.

[0110] The light energy density of the translucent skin-penetrating component 30 also affects the skincare effect. If the light energy density is too low, the skincare effect will not be achieved; if the energy density is too high, it may damage the skin. Therefore, the light energy emitted by the light-emitting device 20 after passing through the translucent skin-penetrating component 30 can be controlled to be 1.96 J / cm². 2 ~5.88J / cm 2 This ensures safety while achieving effective skincare. For example, the light emitted by the light-emitting device 20 can be controlled to have an output energy of 1.96 J / cm² after passing through the translucent skin-penetrating patch 30. 2 2J / cm 2 2.5J / cm 2 3J / cm 2 3.5J / cm 2 4J / cm 2 5.88 J / cm 2 .

[0111] The translucent skin-applied component 30 can be made of a transparent material to facilitate the transmission of light emitted by the light-emitting device 20. The transparent material can be a transparent polymer such as PC or transparent ABS, or a transparent inorganic material such as glass, sapphire, ruby, or diamond. Sapphire is preferred for the translucent skin-applied component 30 because its high light transmittance reduces energy attenuation and thus improves light emission efficiency; additionally, sapphire's good thermal conductivity enhances the cooling effect of the translucent skin-applied component 30.

[0112] In some embodiments, the handle housing 10 has 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 may be formed on the peripheral side portion 13. By arranging 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-size air inlet and increasing the amount of flowing gas entering the device, thereby improving the heat dissipation effect, ensuring the normal operation of the light-emitting device 20, and achieving large-area light emission.

[0113] Furthermore, the first air inlet 16 can be designed to be set on the same side as the light outlet 14. This allows for a large air inlet to be configured on a large side area, which can facilitate large-area air intake while shortening the distance between the air inlet, heat dissipation device 50 and light outlet 14. This facilitates effective heat dissipation of the light-emitting device 20, improves the heat dissipation effect, and ensures large-area light output.

[0114] 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. By providing a second air inlet 18 at the bottom 12 of the handle housing 10, the air intake at the second air inlet 18 at the bottom 12 can remove the heat of the components at the bottom 12, preventing the components from overheating and affecting the light output, and at the same time facilitating handheld use.

[0115] The first air outlet 17 on the handle housing 10 can be formed on the top 11 of the handle housing 10. By setting the first air outlet 17 on the top 11 of the handle housing 10, the light-emitting device 20 is arranged along the length direction of the handle housing 10 between the heat dissipation device 50 and the first air outlet 17. The heat dissipation device 50 can directly blow heat to the light-emitting device 20, which is conducive to improving the heat dissipation effect. In addition, the first air outlet 17 is not easily blocked during operation, which is conducive to the exhaust of hot air and can prevent the air outlet from being blocked and returning to the inside of the handle housing 10. The exhaust hot air does not face the user, which can improve the user experience. In addition, when the light outlet 14 is set on the first side 131 along the length direction of the handle housing 10 near 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 ensures the normal operation of the light-emitting device 20.

[0116] In some embodiments, the first air outlet 17 is formed on the peripheral side 13 of the handle housing 10, and the distance between the first air outlet 17 and the top 11 is less than the distance between the first air outlet 17 and the bottom 12, thus the air outlet is close to the light-emitting device, which is beneficial for 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 form 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 device interior. Dustproof nets can also be provided 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 provided at the first air inlet 16 and the first air outlet 17. The dustproof net 19 is located in the receiving cavity 15 of the handle housing 10. By installing 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 nets 19 installed at the first air outlet 17 can also prevent the blown hot air from flowing back into the handle housing 10.

[0117] The heat dissipation device 50 is mainly used to dissipate heat from the light-emitting device 20. Specifically, the heat dissipation device may 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. With the above structural design, an internal gas flow channel can be formed during the operation of the equipment. Specifically, the air intake from the first air inlet 16 enters the fan 51 through the third air inlet 511 and flows out from the second air outlet 512. After passing through the light-emitting device 20, the heat of the light-emitting device 20 is carried away and discharged from the first air outlet 17, thereby achieving heat dissipation for the light-emitting device 20. Furthermore, the air outlet position of the fan 51 is horizontal with the light-emitting device 20, which can directly blow heat to the light-emitting device 20, avoiding the air being blocked by the light-transmitting skin-contact part 30, ensuring the normal operation of the light-emitting device 20, and reserving space for the arrangement of other components.

[0118] In this embodiment, a heat sink 54 is provided between the second air outlet 512 and the light-emitting device 20. Thus, when in use, the air outlet of the fan 51 can be guided by the heat sink 54 and blow directly onto the light-emitting device 20, carrying away the heat of the light-emitting device 20, thereby achieving effective heat dissipation of the light-emitting device 20 and improving heat dissipation efficiency.

[0119] In addition, in this embodiment, the skin care device also includes a semiconductor cooling chip 60, which is disposed in the receiving cavity 15 of the handle housing 10, and the cold end of the semiconductor cooling chip 60 abuts against the light-transmitting skin-patterning component 30. By setting the semiconductor cooling chip 60 to abut against the light-transmitting skin-patterning component 30 for cooling, the cooled light-transmitting skin-patterning component 30 can use low temperature to apply a cold compress to the care area, effectively preventing the skin of the care area from getting too hot after being exposed to light.

[0120] To further improve the heat dissipation effect of the skin care device, the heat dissipation device 50 may also include a heat dissipation copper pipe 52. The heat dissipation copper pipe 52 is disposed in the receiving cavity 15 of the handle housing 10. One end of the heat dissipation copper pipe 52 is attached to the hot end of the semiconductor cooling chip 60, and the other end of the heat dissipation copper pipe 52 is disposed between the third air inlet 511 and the first air inlet 16. The section of the heat dissipation copper pipe 52 that is attached to the semiconductor cooling chip 60 has a flat structure, and / or the section of the heat dissipation copper pipe 52 located between the third air inlet 511 and the first air inlet 16 has a flat structure. The section of the heat dissipation copper pipe 52 that is in contact with the thermoelectric cooler 60 is designed with a flat structure, which can increase the contact area with the thermoelectric cooler 60, improve the heat dissipation effect, and at the same time reduce the space occupied by the heat dissipation copper pipe 52 on the side, ensuring a large area of ​​light output. The end of the heat dissipation copper pipe 52 away from the thermoelectric cooler 60 is located between the third air inlet 511 and the first air inlet 16. During operation, the heat of the thermoelectric cooler 60 can be conducted to the heat dissipation copper pipe 52, and then the heat is carried away by the air intake from the first air inlet 16 as it passes through the heat dissipation copper pipe 52. The flat structure of this section of the heat dissipation copper pipe 52 can increase its contact area with the air intake, which is conducive to heat dissipation and can reduce the space occupied by the thickness, making it easy to use by hand.

[0121] In this embodiment, the heat dissipation device 50 further includes a second heat dissipation fin 53, which is disposed within the receiving cavity 15 of the handle housing 10 and located between the third air inlet 511 and the first air inlet 16. The end of the heat dissipation copper pipe 52 away from the thermoelectric cooler 60 is thermally connected to the second heat dissipation fin 53. The end of the heat dissipation copper pipe 52 away from the thermoelectric cooler 60 can be positioned to contact the second heat dissipation fin 53 for thermal connection, or it can be designed to pass through and connect to the second heat dissipation fin 53. By setting the second heat dissipation fin 53 to the heat dissipation copper pipe 52 for thermal connection, and with the second heat dissipation fin 53 located between the third air inlet 511 and the first air inlet 16, the heat from the heat dissipation copper pipe 52 can be conducted to the second heat dissipation fin 53. The air intake from the first air inlet 16 passes through the second heat dissipation fin 53, carrying away the heat and thus improving the heat dissipation effect of the heat dissipation copper pipe 52.

[0122] The second heat dissipation fin 53 can be further designed to cover the first air inlet 16, and the dust filter 19 is located between the first air inlet and the second heat dissipation fin 53. This ensures that the incoming air passes through the second heat dissipation fin 53 to the maximum extent, quickly carrying away the heat from the second heat dissipation fin 53, effectively dissipating heat from the copper pipe 52, ensuring the cooling effect of the large-area light outlet 14, and achieving large-area light emission while avoiding skin damage. Of course, in some embodiments, the second heat dissipation fin 53 can also be omitted.

[0123] Additionally, the skin care device may include a circuit board 70, which is disposed within the receiving cavity 15 of the handle housing 10 and located on the side of the light-emitting device 20 opposite to the light outlet 14. The circuit board 70 is electrically connected to the lamp tube 21 and can function as a controller, at least for controlling the on and off of the lamp tube 21. Furthermore, 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 placing the circuit board 70 within the receiving cavity 15 of the handle housing 10 and on the side of the light-emitting device 20 opposite to the light outlet 14, it is convenient to provide power to the electrical device without affecting the light output and handheld operation.

[0124] In addition, the handle housing 10 can be designed with a power socket that is electrically connected to the circuit board 70. The skin care device also includes a power cord that can be connected between the power socket of the handle housing 10 and a computer USB interface 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, the power supply device such as the power adapter can also be set separately from the skin care device. On the one hand, this can reduce the size of the skin care device for easy handheld use, and on the other hand, it eliminates the need for heat dissipation of the power supply device such as the power adapter, thus saving energy.

[0125] In addition, this application also provides a skin care system, which includes the skin care device as described in any of the above embodiments. The skin care system further includes at least one of a charging component, a control device, a placement bracket, and a protective cover. The charging component is disposed outside the skin care device and is electrically connected to the device to supply power. The control device is disposed within or outside the receiving cavity of the skin care device and is communicatively connected to the light-emitting device. The placement bracket is used to house the skin care device. The protective cover protects the light-emitting device of the skin care device.

[0126] Specifically, the charging component can be an energy box, charging base, data cable plug, etc., which can be used to charge the skin care device and control the energy output of the skin care device; 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 the table or other surface in a vertical, tilted or flat position, and can separate the skin care device from the surface to prevent the skin care device from contacting water or dirt on the surface.
