The strong pulse light (intense pulsed light, IPL) is a broad light formed by focusing and filtering a light source with high intensity, and the wavelength of the IPL is 500-1200 nm. The principle of hair removal of the beauty instrument is to use photothermal separation of strong pulsed light, as melanocytes in hair follicles can selectively absorb light in specific wave bands. And the beauty instrument emits IPL light to penetrate the epidermis and directly reach the hair follicle of the dermis. Thus, the light energy is absorbed by melanocytes in the hair follicle within the dermis and converted to heat energy, raising the temperature of the hair follicle. 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.

The LED light (Light Emitting Diode) is a safe cosmetic way by utilizing the luminescence emitted by a narrow-spectrum light source to convert the light energy into the cell energy under the conditions of not generating high heat and not burning the skin. The common LED light in the market at present mainly comprises red light, blue light, filtering light and orange light. 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 green light wave band is absorbed by skin, has tranquilization effect, and helps to lighten pigmentation spots. Exhibiting brighter skin tone. The sedative also has antiinflammatory effect, and can relieve skin surface.

The laser beauty treatment is to make laser beams with specific wavelength penetrate epidermis and dermis to destroy pigment cells and pigment particles, and the fragments are absorbed by macrophages in the body, so that the purposes of safety, no scar left and high efficiency of whitening are achieved.

The beauty instrument of the present disclosure may integrate at least one of three light sources of intense pulsed light, LED light and laser, i.e., the beauty instrument of the present disclosure may provide at least one of the functions of intense pulsed light, LED light and laser by setting the light emitting assembly.

For ease of understanding, the following will be described by taking the example of the cosmetic instrument providing intense pulsed light for depilation.

The luminous principle of the beauty instrument is as follows: the capacitor is connected with the power supply, the voltage of the capacitor is boosted by the voltage transformation component to charge the capacitor, when the capacitor is charged to reach a preset value, and the controller receives a trigger signal, electric energy in the capacitor is released, the instantaneous voltage can reach hundreds of volts, and then the lamp tube is excited to instantly release strong pulse light, so that primary light emission is completed.

As shown in fig. 1, the beauty treatment instrument of the present disclosure mainly includes a housing assembly 100, a power supply assembly 200, a light emitting assembly 300, a cold compress assembly 400, and a heat dissipating assembly 500. Wherein the housing assembly 100 is used to house and carry the various components of the cosmetic device to maintain the various components of the cosmetic device in a predetermined mounting position and to provide protection for the various components of the cosmetic device. The power supply assembly 200 can supply a voltage required for light emission to the light emitting assembly 300 of the beauty instrument by being connected to an external power source. The light emitting assembly 300 may emit a target light (i.e., a strong pulse light) after being energized, through which the cosmetic instrument performs a depilatory function. Since hair follicles can feel a burning sensation to the skin during the rise in temperature of light energy, a cold compress assembly 400 is also provided in the cosmetic device to reduce or even eliminate such burning sensation. The light emitting assembly 300 generates a large amount of heat when emitting strong pulse light and the cold pack assembly 400 generates heat when cooling, so the heat radiating assembly 500 provided in the beauty treatment instrument can reduce the heat generated from the light emitting assembly 300 and the cold pack assembly 400.

As shown in fig. 1 and 2, the housing assembly 100 mainly includes an upper case 101, a lower case 102, a front cover 103, and a rear cover 104. Wherein, the upper shell 101 and the lower shell 102 form a hollow shell structure with two open ends after being buckled, the front end opening is used for arranging the front cover 103, and the rear end opening is used for arranging the rear cover 104. The front cover 103 is provided with a light outlet for emitting the target light out of the beauty instrument. Specifically, the front cover 103 defines a mounting cavity therein within which the cold compress assembly 400 may be received. In some embodiments, the inner wall of the mounting cavity may form a locating structure to cooperate with the cold pack assembly to effect securement of the cold pack assembly. A power connection port may be provided on the rear cover 104 for connection with an external power source. After the upper case 101 and the lower case 102 are fastened, a left case 105 and a right case 106 may be provided on the left and right sides, respectively.

As shown in fig. 3, the light emitting assembly 300 in the beauty instrument of the present disclosure mainly includes a light source 301 (pulse lamp) and a light reflecting member 302 (light reflecting cup). The light source 301 may be a pulse lamp. The reflector 302 may be an arc-shaped housing structure surrounding one side of the light source 301. The filter 303 may have a hard sheet structure or a soft film structure. The light emitting principle of the light emitting assembly 300 is as follows: the light source 301 emits strong pulse light after being energized; the light reflecting member 302 is disposed around the light source 301 for reflecting the strong pulse light emitted from the light source 301 to a predetermined light emitting direction.

In some embodiments, the light emitting assembly further includes a filter 303, where the filter 303 is disposed on the light path of the light source 301, and is used to filter out the light (such as ultraviolet) harmful to human body in the intense pulsed light. The target light filtered out of harmful light acts on human skin, can penetrate through epidermis to directly reach into hair follicle of dermis and be absorbed by melanocyte in hair follicle, thereby raising hair follicle temperature, destroying hair follicle structure and achieving the effect of inhibiting hair growth.

The cold compress assembly 400 in the cosmetic instrument of the present disclosure is located within a cavity formed by the front cover 103 of the cosmetic instrument. As shown in fig. 4-6, the cold pack assembly 400 basically includes a cold pack 401 and a cooling member 402. Wherein the cold pack 401 is made of a light-transmitting material, the cold pack 401 includes a light-in surface 4011, a light-out surface 4012, and a side peripheral surface 4013. The target light emitted from the light emitting module 300 of the cosmetic instrument can enter the cold compress 401 through the light incident surface 4011. The light emitting surface 4012 is opposite to the light entering surface 4011, and when the beauty instrument is used, the light emitting surface 4012 can be attached to the skin of a user and output the target light to the skin of the user. The side surface 4013 is located between the light incident surface 4011 and the light emergent surface 4012, and the side surface 4013 is fixedly engageable with an inner wall of a mounting cavity formed in the front cover 103 to secure the cold pack 401 to the housing assembly 100. The cooling element 402 may be a semiconductor cooling plate, and includes a cooling surface and a heat conducting surface, and after the cooling element 402 is energized, the cooling surface may generate a low temperature, and the cooling surface contacts the light inlet surface 4011 of the cold compress 401, so as to continuously cool the cold compress 401. The cold compress 401 cools the skin surface by direct contact with the skin of the human body, cooling the skin, and thus reducing or even eliminating the burning or painful sensation caused by the warming of hair follicles.

In some embodiments, the cooling element 402 may be an annular cooling plate, and the cooling surface thereof may be attached to an edge of the light inlet surface 4011, so as to reduce the temperature of the cold compress, and the target light may enter the cold compress 401 through a portion of the light inlet surface 4011 not attached by the annular cooling plate.

In the present disclosure, as shown in fig. 5, at least a part of the side circumferential surface 4013 is a microstructure surface (hatched portion in the corresponding drawing). When the target light enters the cold compress 401 through the light incident surface 4011, part of the target light directly reaches the light emergent surface 4012 and is emitted, and the light path of the other part of the target light faces the side surface, at this time, the target light reaching the side surface 4013 is reflected in all directions when being projected to the micro-structural surface due to the micro-structural surface on the side surface 4013, that is, diffuse reflection occurs. The diffuse reflection can change the propagation path of the target light reaching the side peripheral surface 4013, so that the target light is reflected back to the cold compress 401 along different directions when reaching the micro-structural surface, and one part of the reflected target light directly exits from the light-emitting surface of the cold compress 401, and the other part of the reflected target light reaches the micro-structural surface on the other side of the cold compress 401, and continuously undergoes diffuse reflection through the reflection of the micro-structural surface until exiting from the light-emitting surface.

In addition, when the target light is projected to the microstructure surface, the target light can be separated from the original movement direction, and the secondary radiation wave of the target light is scattered and distributed on the angle area according to a certain rule, namely the target light is scattered on the microstructure surface. After the target light is scattered on the microstructure surface, the target light is scattered and spread around, on one hand, the intensity of the part of the target light emitted on the side peripheral surface can be reduced, and the target light emitted from the side peripheral surface is more uniform and softer; on the other hand, a part of the target light scattered and propagated around can directly exit through the light-emitting surface of the cold compress 401, or can reach the microstructure surface on the other side of the cold compress 401, and diffuse reflection and/or scattering can continuously occur, so that the proportion of the target light exiting from the light-emitting surface of the cold compress 401 is further improved.

Therefore, the microstructure surface in the disclosure can make the target light reaching the side surface 4013 have at least one optical phenomenon of diffuse reflection and scattering, and perform multiple diffuse reflection and scattering inside, so that the path of the target light can be changed, the ratio of the target light emitted from the light emitting surface 4012 of the cold compress 401 can be improved, the utilization rate of the target light can be improved, and the dehairing efficiency can be improved; the object light emitted from the side peripheral surface can be more uniform and softer, and the intensity of the object light emitted from the side peripheral surface can be reduced.

In some embodiments, the microstructured surface has scattering dots configured to scatter the target light impinging thereon and diffuse reflecting dots configured to diffuse the target light impinging thereon.

In some embodiments, referring to fig. 8, the shape of the scattering dots may include at least one of circles, polygons, ovals, and wedges (not fully shown in fig. 8). Wherein the circular scattering dots have isotropic scattering; wedge-shaped scattering dots, including Rising wedges (Rising wedges) and Falling wedges (Falling wedges), can properly compensate for dispersion.

In some embodiments, referring to fig. 8, the shape of the diffuse reflecting dots may include at least one of circles, polygons, ovals, and wedges (not fully shown in fig. 8). The above-mentioned shapes such as circles, polygons, ovals, and wedges, when combined and aligned with a very small size, can form a rough surface, i.e., can be part of the microstructured surface of the present disclosure. When the target light reaches the microstructure surface of the side circumferential surface 4013, the target light is irregularly reflected by the roughened surface in various directions.

It will be appreciated that the shape and number of scattering dots on the microstructured surface of the present disclosure may be selected in combination according to the actual requirements. The shape and the number of the diffuse reflection lattice points on the microstructure surface in the disclosure can be combined, selected and set according to actual requirements. Similarly, the arrangement and the number of the scattering dots and the diffuse reflection dots on the microstructure surface in the disclosure can be selected and set in a combined way according to actual requirements.

In some embodiments, as shown in fig. 8, the arrow direction in fig. 8 is the optical path direction of the target light, and the distribution density of the scattering net points provided on the microstructure surface on the side circumferential surface 4013 gradually increases along the optical path direction of the target light. Since the target light enters the cold pack 401 through the light entrance surface 4011, that is, the light entrance surface 4011 of the cold pack 401 is adjacent to the light emitting element 300, the luminous flux is larger near the light emitting element 300, and correspondingly, the luminous flux is smaller far from the light emitting element 300. In the present disclosure, by gradually increasing the distribution density of scattering dots provided on the microstructure surface along the optical path direction of the target light on the side circumferential surface 4013, that is, in the direction from the light incident surface 4011 to the light exit surface 4012. For the target light reaching the microstructure surface far away from the light emitting component 300 on the side peripheral surface 4013, as the luminous flux is less, the distribution density of scattering dots on the microstructure surface is correspondingly improved, so that the probability of scattering the target light can be improved, the probability of emitting the target light from the light emitting surface 4012 of the cold compress 401 is improved, the utilization rate of the target light is improved, and the unhairing efficiency can be improved.

In some embodiments, a light-proof material (not shown) may also be attached to the side peripheral surface 4013. The light-proof material can be selected from black paint, light-proof protective film, etc. Since the cold pack 401 is made of a light-transmitting material, when the target light passes through the cold pack 401, a part of the target light is inevitably emitted from the side circumferential surface 4013 of the cold pack 401, and the part of the target light may be irradiated to non-dehaired parts (for example, eyes, eyelashes, eyebrows, etc.), causing a false injury. Therefore, by attaching the light-transmitting-preventing material to the side circumferential surface 4013, the target light reaching the side circumferential surface 4013 can be absorbed, the light transmittance of the target light on the side circumferential surface 4013 can be reduced, and the use safety of the cosmetic instrument can be improved. In the present disclosure, the light-transmitting preventing material may be attached to the entire region of the side circumferential surface 4013, or the light-transmitting preventing material may be attached to a partial region of the side circumferential surface 4013.

In some embodiments, a reflective metal sleeve (not shown) may be further sleeved on the side peripheral surface 4013, and the reflective metal sleeve may reflect the target light emitted out of the side peripheral surface back into the cold compress 401, so that the light transmittance of the target light on the side peripheral surface 4013 may be reduced. When the outer surface of the side circumferential surface 4013 is sleeved with the light-reflecting metal sleeve, a certain space is reserved between the side circumferential surface 4013 and the inner wall of the mounting cavity of the front cover 103 to accommodate the light-reflecting metal sleeve due to certain rigidity and thickness of the light-reflecting metal sleeve. In the present disclosure, when the light reflecting metal sleeve is provided on the side circumferential surface 4013, the light reflecting metal sleeve may be provided on the entire region of the side circumferential surface 4013, or the light reflecting metal sleeve may be provided on a partial region of the side circumferential surface 4013.

As described above, since at least a part of the side circumferential surface 4013 is a microstructured surface in the present disclosure. Thus, the microstructure surface may be the entire region of the side circumferential surface 4013, or may be a partial region of the side circumferential surface 4013. Accordingly, when the light-transmitting preventing material is attached to the side peripheral surface 4013, the light-transmitting preventing material may be attached to the micro-structural surface, and the light-transmitting preventing material may be attached to other areas of the side peripheral surface 4013 than the micro-structural surface. When the side peripheral surface 4013 is sleeved with the reflective metal sleeve, the reflective metal sleeve can be sleeved on the microstructure surface, and the reflective metal sleeve can also be sleeved on other areas except the microstructure surface on the side peripheral surface 4013.

In the present disclosure, the light incident surface 4011 and the light emergent surface 4012 of the cold compress 401 may be polished surfaces. Compared with the situation without polishing treatment, after polishing treatment is performed on the light incident surface 4011 and the light emergent surface 4012 of the cold compress 401, the light transmittance of the light incident surface 4011 and the light emergent surface 4012 can be improved, so that the proportion of target light incident through the light incident surface 4011 and emergent from the light emergent surface 4012 to the skin of a user is improved, and the depilating effect is also improved after the utilization rate of the target light is improved.

In the present disclosure, the material of the cold compress 401 may be a light-transmitting material such as sapphire, quartz glass, or crystal. The sapphire has good skin-friendly touch feeling, can reach low temperature close to zero degree, really enables the temperature of the skin near the light outlet to be infinitely close to the freezing point, greatly relieves the burning sensation of the skin, and can not cause skin injury in short-time contact.

In some embodiments, the cold compress 401 may be in the shape of a cylinder, prism, truncated cone, truncated pyramid, or the like.

In some embodiments, to improve the securement of the cold pack 401 to the housing assembly 100, the cold pack 401 may be designed to form a number of stepped structures connected in sequence along the direction of propagation of the target light. As shown in fig. 9, the cold pack 401 includes a first step 401-a and a second step 401-b connected in sequence along the propagation direction of the target light, and the junction of the first step 401-a and the second step 401-b forms a step surface 4014. In the present disclosure, the step surface 4014 may cooperate with a positioning structure on an inner wall of the installation cavity formed by the front cover 103, so as to limit the degree of freedom of the cold compress member along the propagation direction of the target light, and improve the firmness of fixing the cold compress member 401 to the housing assembly 100.

It is understood that the number of steps included in the cold pack 401 may be set as is practical and that the number and shape of steps shown in fig. 4-7, 9 are not limiting to the cold packs of the present disclosure.

Referring to fig. 6 to 7, the light incident surface 4011 is an end surface of the first step structure 401-a away from the second step structure 401-b, the light emergent surface 4012 is an end surface of the second step structure 401-b away from the first step structure 401-a, and the side circumferential surface 4013 includes a first side circumferential surface 4013-a of the first step structure 401-a and a second side circumferential surface 4013-b of the second step structure 401-b.

In the present disclosure, at least a part of the region of the first side circumferential surface 4013-a is a microstructured surface, and at least a part of the second side circumferential surface 4013-b is a microstructured surface. And since the side peripheral surface 4013 of the cold pack 401 includes the first side peripheral surface 4013-a and the second side peripheral surface 4013-b, the first side peripheral surface 4013-a and the second side peripheral surface 4013-b may each be a microstructured surface, only the first side peripheral surface 4013-a may be a microstructured surface, only the second side peripheral surface 4013-b may be a microstructured surface, or all of the first side peripheral surface 4013-a and the second side peripheral surface 4013-b may be a microstructured surface. It should be appreciated that one skilled in the art can select the area covered by the microstructured surface on the lateral perimeter 4013 of the cold pack 401 as desired. At this time, when the light-transmitting-preventing material is attached to the side peripheral surface 4013 of the cold pack 401, the light-transmitting-preventing material may be attached to the first side peripheral surface 4013-a, the second side peripheral surface 4013-b, or the light-transmitting-preventing material may be attached to both the first side peripheral surface 4013-a and the second side peripheral surface 4013-b. Accordingly, when a light reflecting metal sleeve is provided on the side peripheral surface 4013 of the cold compress 401, the light reflecting metal sleeve may be provided on the first side peripheral surface 4013-a, the second side peripheral surface 4013-b, or both the first side peripheral surface 4013-a and the second side peripheral surface 4013-b.

In some embodiments, at least a portion of the step surface 4014 is a microstructured surface. For example, as shown in fig. 9, the entire area of the step surface 4014 is a microstructure surface. Alternatively, a partial region of the step surface 4014 is a microstructure surface (not shown in the drawing). It will be appreciated that the person skilled in the art can choose the area covered by the microstructured surface on the step surface 4014 by himself as desired.
