[0039] See Figures 1 to 5This embodiment provides a skin care device, which includes a housing 1 and a care light source 2. The housing 1 is constructed as a shell structure of the skin care device, and the interior of the housing 1 is hollow to accommodate relevant functional components and structural components of the skin care device.

[0040] In some embodiments, the housing 1 is annular, so that the housing 1 forms a through irradiation channel 12 along its axial direction, and the irradiation channel 12 is used to accommodate the torso of the user to be cared for. The torso can be the user's arms, legs, neck, waist and other parts. During beauty treatment, the torso of the user extends into the irradiation channel 12, and the inner peripheral wall of the irradiation channel 12 surrounds the torso.

[0041] In some embodiments, the shell 1 may be in a circular ring shape, a rectangular ring shape, a triangular ring shape, etc., as long as a through irradiation channel 12 can be formed along the axial direction to facilitate the user's torso to enter.

[0042] In this embodiment, the shell 1 is annular, and the irradiation channel 12 formed by the inner peripheral wall of the shell 1 is a circular channel to facilitate the insertion of the torso. The outer peripheral wall contour of the shell 1 is circular to avoid the formation of sharp edges that may cause harm to the user.

[0043] In some embodiments, the housing 1 is provided with an annular cavity 13, and the inner and outer circumferential walls of the annular cavity 13 correspond to the inner and outer circumferential walls of the housing 1. The inner circumferential wall of the annular cavity 13 is provided with a light-transmitting area, which can transmit light waves.

[0044] In some embodiments, the housing 1 may include a first half shell 10 and a second half shell 11. The first half shell 10 and the second half shell 11 may be fan-shaped, and both the first half shell 10 and the second half shell 11 have fan-shaped ring cavities. The first half shell 10 and the second half shell 11 are assembled opposite to each other to form the housing 1, and the two fan-shaped ring cavities are enclosed to form a ring cavity 13. The first half shell 10 and the second half shell 11 may have the same structure, and the corresponding central angle may be 180 degrees, which is convenient for improving manufacturing efficiency.

[0045] In some embodiments, a grip portion 8 is convexly provided on the outer peripheral wall of the housing 1, so that the user can operate the skin care device through the grip portion 8, and the grip portion 8 provides a point of force for the user. The grip portion 8 can be U-shaped, with both ends connected to the outer peripheral wall of the housing 1, so that the user can hold the grip portion 8 when operating. The grip portion 8 can be connected to the housing by screws, or welded to the housing, or can be integrally formed with the housing.

[0046] In some embodiments, the holding portion 8 can be separately provided on the first half-shell 10 or the second half-shell 11. It can also be partially located on the first half-shell 10 and partially located on the second half-shell 11. When the first half-shell 10 and the second half-shell 11 are assembled to form the housing 1, the two parts of the holding portion 8 can be combined to form a complete holding portion 8.

[0047] In some embodiments, the skin care light source 2 is disposed in the annular cavity 13. The skin care light source 2 can emit light waves of a specific wavelength toward the light-transmitting area. The light waves can irradiate the human torso accommodated in the irradiation channel 12 through the light-transmitting area, so as to perform beauty care on the skin on the torso by using the light waves.

[0048] In this embodiment, the light-transmitting area can be annular, so that the light-transmitting area forms an annular light-emitting surface. The skin care light source 2 can perform omnidirectional irradiation on the trunk part in the irradiation channel 12 without leaving any dead corners, avoiding the situation of discontinuous and uneven skin beautification areas, and greatly improving the skin beautification effect.

[0049] It should be noted that the skin care light source 2 emits light waves with specific wavelengths for skin care purposes. For example, the skin care light source 2 can generate red light with a wavelength of 660 nm, blue light with a wavelength of 415 nm, yellow light with a wavelength of 590 nm, etc. The corresponding functions can improve skin color uniformity, regulate sebum secretion and inhibit melanin formation, so as to achieve the effect of skin care. Users can select light waves of different wavelengths according to their needs. Of course, the wavelengths of the light waves can also be other specific wavelengths, which will not be elaborated here. The skin care light source 2 can also emit intense pulsed light. The intense pulsed light is colored light with wavelengths ranging from 475 - 1200 nm, which has a hair removal effect and combines multiple treatment functions.

[0050] See Figure 2 and Figure 3 , in some embodiments, the skin care instrument further includes a control component. The control component can include a controller 6 and a control line 7. The controller 6 is disposed outside the housing 1. The controller 6 is electrically connected to the skin care light source 2 through the control line 7 to control the skin care light source 2 to emit light waves.

[0051] Among them, the controller 6 can include a controller housing 61 and a control main board 62. The controller housing 61 includes a controller upper shell 610 and a controller lower shell 611 covered thereon, so that a control cavity is formed inside the controller housing 61. The control main board 62 is disposed in the controller housing 61, which is convenient for installing the control main board 62. The control main board 62 is electrically connected to the skin care light source 2 located in the annular cavity 13 through the control line 7. A function button 63 is provided on the controller housing 61. The function button 63 is connected to the control main board 62. There can be multiple function buttons 63 to respectively select the on / off of the skin care light source 2 or the beauty care mode, etc., so as to control the skin care instrument and facilitate user operation.

[0052] In this embodiment, the controller 6 located outside the housing 1 is electrically connected to the skin care light source 2 inside the housing 1 through the control line 7, so that when the skin care instrument is set on the trunk, the skin care instrument can be remotely controlled at a distance, avoiding the user from bending down to operate the skin care instrument, thereby improving the use experience of the skin care instrument.

[0053] See Figures 6 to 8 , in some other embodiments, the holding part 8 is hollow inside and forms an installation cavity 80 communicating with the annular cavity 13. The controller can be arranged in the installation cavity 80, so as to use the holding part 8 to accommodate the controller and make the skin care instrument more concise.

[0054] It can be understood that when the controller 6 is arranged in the installation cavity 80, the controller 6 can only include the control main board 62, and the controller housing 61 can be removed, and the holding part 8 protects the control main board 62. The control main board 62 can be electrically connected to the skin care light source 2 through a wire from the installation cavity 80 to the annular cavity 13. Correspondingly, the outer wall of the holding part 8 is provided with a function button 63 connected to the control main board 62. Installation holes can be arranged on the outer wall of the holding part 8, and the function button 63 can be clamped in the installation holes and extend into the installation cavity 80 to be connected to the control main board 62. By arranging the control main board 62 in the holding part 8, it is integrated with the housing 1, making the structure of the skin care instrument more integrated and facilitating the storage of the skin care instrument.

[0055] In some embodiments, the skin care instrument further includes a lens 3, and the lens 3 can allow light waves to pass through. An annular notch is provided on the inner peripheral wall of the housing 1, and the lens 3 is connected in alignment with the annular notch, so that the lens 3 is installed on the housing 1. The lens 3 constitutes a light transmission area, and the light waves pass through the lens 3 and irradiate the trunk part of the human body located in the irradiation channel 12. The lens 3 can focus the light waves to increase the light intensity. The inner side surface of the lens 3 constitutes the inner wall of the irradiation channel 12, and the outer side surface of the lens 3 constitutes a part of the inner peripheral wall of the annular cavity 13.

[0056] In some embodiments, the skin care light source 2 has a plurality of light emitting parts, and the plurality of light emitting parts are circumferentially spaced along the annular cavity 13. The light emitting parts can emit light waves for skin beautification towards the light transmission area, thereby increasing the light intensity of each area in the light transmission area, so that good irradiation and skin beautification effects can be achieved on each position area on the circumference of the trunk part extending into the irradiation channel 12. Among them, the plurality of light emitting parts can be circumferentially and evenly spaced along the annular cavity 13, so that each area is irradiated by uniform light waves.

[0057] In this embodiment, the nursing light source 2 includes a first light source 20 and a second light source 21. The first light source 20 may include a flexible circuit board 201 and a plurality of LED lamp beads 202 disposed on the flexible circuit board 201. The LED lamp beads 202 form a light emitting portion to emit light waves. The flexible circuit board 201 is flexible and can be bent so that the flexible circuit board 201 is arranged in a ring shape. The flexible circuit board 201 is sleeved on the inner peripheral wall of the annular cavity 13, that is, sleeved on the lens 3. The plurality of LED lamp beads 202 are arranged at intervals along the circumferential direction of the flexible circuit board 201 so as to surround the light transmission area, so that each position of the light transmission area can be irradiated by the LED lamp beads 202. The light waves emitted by the LED lamp beads 202 can irradiate the human trunk part located in the irradiation channel 12 after passing through the light transmission area. The LED lamp beads 202 constitute the above-mentioned light emitting portion.

[0058] It can be understood that the plurality of LED lamp beads 202 are located on the side of the flexible circuit board 201 facing the light transmission area, so that the light waves can be irradiated towards the light transmission area. The LED lamp beads 202 are electrically connected to the flexible circuit board 201, and the flexible circuit board 201 controls the light emission of the LED lamp beads 202. The flexible circuit board 201 can be electrically connected to the control main board 62 to receive the instructions of the control main board 62 and control the light emission of the LED lamp beads 202 according to the instructions.

[0059] It can be understood that the LED lamp beads 202 can directly emit light of different colors and can generate light waves with specific wavelengths for skin care. Their energy is low and the safety is good. The red light emitted can improve skin microcirculation, promote the repair of damaged skin and wound healing. The yellow light emitted can reduce local skin sensitivity and has an anti-inflammatory effect. The blue light emitted can treat acne through the photodynamic effect.

[0060] In some embodiments, the plurality of LED lamp beads 202 may be arranged at intervals along the axial direction of the flexible circuit board 201 to form multiple groups of LED lamp beads 202. The multiple groups of LED lamp beads 202 are arranged at intervals along the circumferential direction of the flexible circuit board 201 so that the plurality of LED lamp beads 202 are evenly distributed.

[0061] In this embodiment, a plurality of avoidance positions 203 are provided at intervals along the circumferential direction of the flexible circuit board 201. The avoidance positions 203 are used for installing the second light source 21.

[0062] In this embodiment, the second light source 21 may include a plurality of xenon lamps 210. The plurality of xenon lamps 210 are respectively disposed in a plurality of avoidance positions 203. The plurality of xenon lamps 210 are circumferentially spaced along the circumference of the annular cavity 13. The xenon lamps 210 constitute the above-mentioned light-emitting part. Among them, the avoidance position 203 may be a through hole provided on the flexible circuit board 201. The light-emitting part of the xenon lamp 210 can be snapped into the avoidance position 203, so that the LED lamp beads 202 and the xenon lamps 210 do not interfere with each other, and the two can emit light separately or simultaneously.

[0063] It should be noted that the xenon lamp 210 can generate intense pulsed light, which is a kind of broadband light with a light wave wavelength between 500nm and 1200nm and relatively strong energy. It can destroy pigment cells and blood vessels in the skin with the energy of intense pulsed light, thereby improving problems such as pigmentation and blood vessel dilation. Among them, the xenon lamp 210 can be a light-emitting lamp tube filled with xenon.

[0064] Among them, the xenon lamp 210 includes a light-emitting tube body 211, a reflector 212 and a filter 213. The reflector 212 forms a reflecting cavity with one end open. The light-emitting tube body 211 is disposed in the reflecting cavity. The open end of the reflecting cavity faces the light-transmitting area, so that the light waves emitted by the light-emitting tube body 211 enter the irradiation channel 12 through the reflection of the inner wall of the reflecting cavity and then through the light-transmitting area, which can improve the light intensity of the light waves. It can be understood that the light-emitting tube body 211 is the main part of the xenon lamp 210, and xenon is filled inside to form a xenon light-emitting lamp tube. The reflector 212 can be partially snapped into the avoidance position 203 so that the light waves emitted by the light-emitting tube body 211 enter the light-transmitting area through the avoidance position 203.

[0065] In some embodiments, notches may be correspondingly provided on two opposite side walls of the reflector 212, and the notches are opened towards the light-transmitting area. When installing the light-emitting tube body 211, both ends of the light-emitting tube body 211 are clamped in the corresponding notches, and the light-emitting part of the light-emitting tube body 211 is located in the reflecting cavity.

[0066] Since the xenon lamp 210 emits a kind of broadband light, when beautifying the skin, it is necessary to filter out light waves with unnecessary wavelengths to select the light waves with the required wavelengths. Therefore, by providing the filter 213, the filter 213 covers the open end of the reflecting cavity so that the light waves emitted by the light-emitting tube body 211 can be filtered by the filter 213 before being emitted to the light-transmitting area, thereby obtaining light waves with specific wavelengths.

[0067] In this embodiment, by simultaneously providing the first light source 20 and the second light source 21, the skin care instrument can have more skin care functions, which is convenient for users to select and enable the corresponding first light source 20 and / or second light source 21 according to their skin care needs, improving the use experience of the skin care instrument.

[0068] In some other embodiments, the skin care light source 2 may also only include the first light source 20 and not be provided with the second light source 21. When only the second light source 21 is provided, the flexible circuit board 201 is not provided with an avoidance position 203, the flexible circuit board 201 is in a complete ring shape, and a plurality of LED lamp beads 202 are arranged at intervals along the circumferential direction of the flexible circuit board 201 and are located on the side of the flexible circuit board 201 facing the light-transmitting area. The LED lamp beads 202 alone constitute the above-mentioned light-emitting part.

[0069] In some other embodiments, the skin care light source 2 may also only include the second light source 21 and not be provided with the first light source 20. When the first light source 20 is not provided, a plurality of xenon lamp tubes 210 are distributed at intervals along the circumferential direction of the annular cavity 13, and the xenon lamp tubes 210 alone constitute the above-mentioned light-reflecting part.

[0070] In some embodiments, the skin care instrument further includes a capacitor 4. The capacitor 4 is arranged in the annular cavity 13, and the capacitor 4 is electrically connected to the skin care light source 2 to supply power to the skin care light source 2 through the electric energy stored in the capacitor 4, so that the skin care light source 2 can emit light waves for skin beautification. Specifically, the capacitor 4 is electrically connected to the first light source 20 and the second light source 21 to supply power to the first light source 20 and the second light source 21. Two capacitors 4 can also be provided, which extend along the axis direction of the housing 1 and are arranged in the annular cavity. The two capacitors 4 can be respectively electrically connected to the first light source 20 and the second light source 21 to supply power to them respectively. It can be understood that the capacitor 4 is also electrically connected to the control main board 62 to supply power to the control main board 62, so that the control main board 62 can control the light emission of the skin care light source 2.

[0071] In some embodiments, the skin care instrument further includes a fan 5. The fan 5 is arranged in the annular cavity 13. A heat dissipation hole 14 communicating with the outside is provided on the outer circumferential wall of the annular cavity 13. The annular cavity 13 convects with the outside air through the heat dissipation hole 14. The fan 5 can accelerate the convection speed of the air in the annular cavity 13 with the outside through the heat dissipation hole 14, so that the fan 5 is used to dissipate heat from the annular cavity 13 through the heat dissipation hole 14, avoiding overheating of the skin care light source 2 after long-term operation, so as to protect the skin care instrument. It can be understood that two fans 5 can be provided, and the two fans 5 are symmetrically arranged with respect to the annular cavity 13, so that the air in the annular cavity 13 is evenly fanned by the fan blades of the fan 5. A plurality of heat dissipation holes 14 are arranged at intervals along the circumferential direction of the housing 1 and can be opposite to the position of the fan 5.
