As used herein, the singular is also intended to include the plural unless the context clearly indicates otherwise, and furthermore, it is to be understood that the terms "comprises" and/or "comprising" when used in this specification are taken to specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof.

The present utility model provides a skin treatment device, please refer to fig. 1 to 27, the skin treatment device comprises a housing assembly 10, a light transmissive member 20, a first light emitting assembly 30 and a second light emitting assembly 40; the housing assembly 10 has an exit port 11; the light-transmitting member 20, the first light-emitting component 30 and the second light-emitting component 40 are all arranged in the shell component 10, and the light-transmitting member 20 comprises an emergent surface 21; the first light emitting component 30 is configured to emit a first light toward the light transmitting member 20, so that the light transmitting member 20 emits at least a portion of the first light through the emitting surface 21 and the emitting opening 11 for phototherapy on skin, thereby enabling the skin treatment device to have a phototherapy instrument function; i.e. the first light emitting component 30 is a phototherapy component; the second light emitting component 40 is configured to emit a second light toward the light transmitting member 20, so that the light transmitting member 20 emits at least a portion of the second light through the emitting surface 21 and the emitting opening 11 for depilating and/or rejuvenating the skin, thereby enabling the skin treatment device to function as a depilatory instrument and/or a skin rejuvenating instrument; that is, the second light emitting component 40 is a depilating component, a skin rejuvenating component, or a component having both depilating and skin rejuvenating functions.

The skin treatment device not only can carry out phototherapy on skin, but also can carry out dehairing and/or skin rejuvenation, and the first light ray and the second light ray of the skin treatment device can be emitted from the emergent surface 21, so that the first light ray and the second light ray emitted from the emergent surface 21 and the emergent port 11 can act on the same skin part at the same time, and the skin treatment device can carry out different skin treatments on the same skin part at the same time or sequentially; that is, the skin treatment device of the present application can simultaneously perform phototherapy on a skin portion to be dehaired, and also can timely perform phototherapy on a dehaired skin portion, so as to improve the use experience. Therefore, the skin treatment device has better experience, and solves the problem that the skin treatment device in the prior art has poorer use experience because the skin treatment device cannot simultaneously depilation and phototherapy on the same skin part.

In addition, the existing skin treatment device needs to additionally provide a light transmission area of the second light on the light-emitting end surface of the shell component, and the light transmission area of the second light necessarily occupies a part of the light-emitting end surface, so that the size of the light-emitting opening is limited by the light transmission area of the second light; the first light and the second light are emitted from the emitting surface 21 and the emitting opening 11, so that the light transmission area of the second light is omitted, the size of the emitting opening 11 is not limited, and the emitting opening 11 and the emitting surface 21 are increased; that is, the ratio of the emitting surface 21 to the emitting port 11 on the emitting end surface 12 of the housing assembly 10 (for example, more than 90%) is advantageously increased, and the emitting end surface 12 is the surface of the housing assembly on which the emitting port 11 is located, so that the effective emitting area on the emitting end surface 12 is advantageously increased.

In addition, the blank area on the light emitting end face of the existing skin treatment device is large, and the blank area is an area indicating the outer periphery side of the light emitting opening on the light emitting end face, so that when the light emitting end face moves upwards on the skin, the position of the light emitting face and the next action area of the light emitting opening on the skin are inconvenient; the blank area on the light emitting end face 12 of the skin treatment device is smaller, so that the next action area of the light emitting opening 11 and the light emitting face 21 on the skin can be accurately positioned, and great convenience is brought to the skin treatment process.

Specifically, the transparent member 20 is a transparent crystal, and the transparent crystal is made of at least one of sapphire, quartz glass, and crystal. The sapphire has good skin-friendly touch feeling, and can reach low temperature close to zero degree through matching with a refrigerating piece, so that the temperature of the skin near the outlet 11 is infinitely close to a freezing point, the burning sensation of the skin is greatly relieved, and skin damage is not caused by short-time contact; the cooperation of sapphire and refrigeration piece means that refrigeration piece and sapphire heat conduction are connected to make refrigeration piece carry out cooling to the sapphire.

Optionally, the second light emitting component 40 is a IPL (Intense Pulsed Light) light emitting light source component, so that the second light is strong pulsed light, which is also called pulsed strong light; the strong pulse light is a broad light formed by focusing and filtering a light source with high intensity, the wavelength of IPL is 400nm to 200nm, and different wavelengths have different effects. For example, when the IPL has a wavelength of 690nm to 1200nm, it mainly uses the photothermolysis principle of intense pulsed light to have an epilation effect; since melanocytes in hair follicles can selectively absorb light of a specific wavelength band, and IPL light can penetrate epidermis and directly reach into hair follicles of dermis; the light energy is absorbed by melanocytes in hair follicles in dermis and converted into heat energy, raising the temperature of hair follicles; when the temperature of the hair follicle rises to be high enough, the hair follicle structure is irreversibly destroyed, and the destroyed hair follicle naturally falls off after a period of time, so that the hair growth is delayed or even the extension is stopped in a short period of time. IPL has a skin rejuvenating effect mainly when the wavelength of IPL is 560nm to 640 nm. Alternatively, the second light emitting element 40 is a laser light emitting element so that the second light is a laser light to achieve depilation by the laser.

Optionally, the first light includes at least one of red light, blue light, yellow light; wherein, the wavelength of blue light is 450nm to 490nm, the wavelength of yellow light is 567nm to 607nm, and the wavelength of red light is 620nm to 660nm.

For example, the first light ray, which includes LED (Light Emitting Diode) light, is luminescence emitted by a narrow spectrum light source, and converts light energy into cellular energy without generating high heat and burning skin, which is a safe cosmetic way. Wherein, the LED red light wave band can promote whitening and tendering skin, and lighten spots and remove wrinkles; the LED blue light wave band can promote deep sterilization and balance grease; the LED orange light wave band can supplement cell energy, strengthen muscles, improve relaxation and the like; the LED green light wave band is absorbed by skin, has tranquilization effect, is helpful for lightening pigmentation spots, and shows brighter skin color, and the tranquilization effect also has antiinflammatory effect, and can relieve skin surface.

In an embodiment, the light-transmitting member 20 further includes a light-incident surface 22 disposed opposite to the light-emitting surface 21, and the second light-emitting component 40 is configured to emit a second light toward the light-incident surface 22.

Specifically, the second light emitting assembly 40 includes a second light emitting portion 41 for emitting a second light, where the second light emitting portion 41 is disposed opposite to the light incident surface 22, so that the second light emitted by the second light emitting portion 41 is incident into the light transmitting member 20 through the light incident surface 22 and then is emitted through the light emitting surface 21.

In an embodiment, the light-transmitting member 20 further includes a side portion 23 connected between the light-emitting surface 21 and the light-incident surface 22, and the first light-emitting component 30 is configured to emit a first light toward the side portion 23.

Specifically, the side surface 23 includes a first side surface 231, the first light emitting assembly 30 includes a first light emitting portion 31 for emitting a first light, and the first light emitting portion 31 is disposed opposite to the first side surface 231 to emit the first light into the light transmitting member 20 through the first side surface 231.

Because the first light-emitting component 30 and the second light-emitting component 40 are respectively disposed at different orientations of the transparent member 20, the incident orientations of the first light and the second light are different, and the emergent paths of the first light and the second light passing through the transparent member 20 are different, but the emergent surfaces are the same, so that the first light and the second light can realize different functional superposition of the skin treatment device, but the structures of the first light-emitting component 30 and the second light-emitting component 40 are not mutually affected. For example, the first light emitting assembly 30 and the second light emitting assembly 40 may be turned on simultaneously to achieve a superposition of phototherapy with depilatory and/or skin rejuvenation functions. It is also possible to turn on only the first light emitting element 30 to achieve a phototherapy function; it is also possible to switch on only the second light emitting assembly 40 for achieving a depilatory and/or skin rejuvenation function.

Alternatively, at least one side 230 among the remaining sides 230 except the first side 231 among the plurality of sides 230 is a diffuse reflection surface so that the side 230 which is a diffuse reflection surface can be diffusely reflected; for example, at least one side 230 is a roughened surface with microstructures to form a diffuse reflecting surface. The light entering the light transmitting member 20 is emitted through the emitting surface 21 after being diffusely reflected and/or reflected by the reflective film provided on the side surface 230 or the side surface 230 is made to be a diffuse reflection surface, so that the light extraction efficiency is further improved, and the loss of the first light and/or the second light is reduced. In addition, the diffuse reflection effect of the diffuse reflection surface can improve the uniformity and softness of the light and ensure the light-emitting rate.

Specifically, the reflective film may be a metal reflective film or a total dielectric reflective film, or may be a reflective film in which a metal reflective film and a total dielectric reflective film are combined.

Optionally, the thickness of the reflective film is d,0.1 mm.ltoreq.d.ltoreq.0.2 mm. The thickness of the reflective film is thinner, so that light reflection can be realized, and heat dissipation of the light-transmitting piece 20 is not affected.

Alternatively, the side portion 23 includes four side surfaces 230 connected in sequence; preferably, the light-transmitting member 20 is a rectangular parallelepiped. Alternatively, the light transmissive member 20 is a cylinder or prism.

Alternatively, the exit surface 21 is a rectangular plane, or a circular plane, or an arc surface; the light incident surface 22 is a rectangular plane, a circular plane or an arc surface; the side 230 is rectangular in plan, or circular in plan, or arcuate in shape. For example, the light incident surface 22 in fig. 21 is an arc surface, that is, the cross section of the light incident surface 22 in fig. 21 is an arc; the light incident surface 22 in fig. 22 is a bending surface, and the bending surface is formed by three planes, that is, the cross section of the light incident surface 22 in fig. 22 is trapezoidal; the light incident surface 22 in fig. 23 is formed of two planes, that is, the cross section of the light incident surface 22 in fig. 23 is V-shaped; the exit face 21 and the first side 231 in fig. 24 are rectangular planes. It is noted here that the light incident surface 22 may be a curved surface constituted by two, three, or even more flat or curved surfaces. In fig. 24, the light-transmitting member 20 is a triangular prism, the top surface of the triangular prism is a first side surface 231, and two side surfaces of the triangular prism are an incident surface 22 and an emergent surface 21 respectively.

In one embodiment, the exit face 21 is located at the exit 11.

Specifically, the exit face 21 and the face where the exit port 11 is located are in the same plane; alternatively, at least part of the exit surface 21 is arranged protruding towards the outside of the housing assembly 10 with respect to the surface where the exit opening 11 is located.

Specifically, the inner wall of the exit 11 is bonded to the side surface portion 23 of the light transmitting member 20.

In an embodiment, the light incident surface 22 is a diffuse reflection surface, so that at least a portion of the first light irradiated into the light-transmitting member 20 can be emitted from the light emergent surface 21 under the diffuse reflection effect of the light incident surface 22.

Specifically, the light incident surface 22 is provided with a plurality of protruding portions 221, and the protruding portions 221 are protruding in a direction away from the light emergent surface 21, so that the light incident surface 22 is a diffuse reflection surface. Wherein one of the protrusions 221 constitutes one diffuse reflecting dot. In addition, the diffuse reflection effect of the diffuse reflection surface formed by the plurality of convex parts 221 can better guide light and diffuse reflection, thereby improving the light emitting uniformity and softness of light rays and ensuring the light emitting rate.

Specifically, the convex portion 221 is a slightly convex structure to form a rough surface.

Specifically, the boss 221 is formed by an etching process. The etching process refers to a process of removing a thin film layer not masked by a resist to obtain exactly the same pattern on the thin film as on the resist film. Etching can be performed chemically, or physically, or both, to selectively remove portions of the thin film layer not masked by the resist, thereby obtaining a pattern on the thin film that is completely consistent with the pattern on the resist film. The etching technology is mainly divided into dry etching and wet etching. The dry etching mainly uses the reaction gas and the plasma for etching; the wet etching mainly uses chemical reagents to chemically react with the etched material for etching. Etching processes are well known in the art, and are well known in the industry, thereby facilitating the reduction of manufacturing costs.

Specifically, the plurality of protruding portions 221 are spaced apart on the light incident surface 22.

Alternatively, the projection of the boss 221 on the light incident surface 22 is circular, polygonal, elliptical, or irregular in shape.

Alternatively, the projection diameter or equivalent diameter of the protrusion 221 on the light incident surface 22 has a value ranging from 20 micrometers to 50 micrometers; for example, the diameter or equivalent diameter is 20 microns, or 25 microns, or 30 microns, or 36 microns, or 40 microns, or 44 microns, or 50 microns.

Alternatively, the protruding height of the protruding portion 221 may have a value ranging from 5 micrometers to 15 micrometers; for example, the protrusion height is 5 microns, or 6 microns, or 8 microns, or 10 microns, or 11 microns, or 13 microns, or 15 microns.

Optionally, the plurality of sides 230 includes a second side 232 disposed opposite the first side 231. Since light enters the light-transmitting member 20 through the first side 231, i.e., the first side 231 is adjacent to the first light-emitting element 30, the luminous flux is larger near the first light-emitting element 30, and smaller far from the first light-emitting element 30. As shown in fig. 19, the distribution density of the protrusions 221 gradually increases from the first side 231 to the second side 232; for the light reaching the diffuse reflection surface on the light incident surface 22 far from the first light emitting component 30, as the luminous flux is less, the distribution density of the scattering dots on the diffuse reflection surface is correspondingly improved, so that the probability of scattering the light can be improved, the probability of emitting the light from the emitting surface 21 of the light transmitting member 20 is improved, the light utilization rate is improved, and the phototherapy efficiency is improved. The arrow direction in fig. 19 is the direction from the first side 231 to the second side 232. Alternatively, as shown in fig. 18, the plurality of protruding portions 221 are uniformly distributed on the light incident surface 22.
