Example 1

The embodiment provides a heat dissipation structure of a beauty instrument, which is used for solving the problems of serious heating, poor heat dissipation capability and influence on use experience of the beauty instrument in the related technology.

Referring to fig. 1 to 3, a heat dissipation structure of a cosmetic apparatus includes: cooling channel 120, reflector assembly 200, and semiconductor cooling assembly 300. The end of the cooling channel 120 is provided with a light emitting assembly 500; the end part of the cooling channel 120 is also provided with a light guide block 110, and the light emitting component 500 can be abutted against the light guide block 110; cooling air flows through the cooling duct 120. The light reflecting assembly 200 is wound around the outside of the light emitting assembly 500. The semiconductor cooling assembly 300 is disposed in the cooling channel 120, and an end of the semiconductor cooling assembly 300 abuts against the light guide block 110 and is disposed near the light reflecting assembly 200.

Specifically, the heat dissipation structure of the beauty instrument of the embodiment can effectively cool and dissipate heat of the beauty instrument. The light emitting component 500 in the cosmetic instrument is usually a tungsten filament lamp, and the tungsten filament lamp emits light with a wide spectrum when in operation, and carries infrared radiation heat, so that the heat of the tungsten filament lamp and the surrounding is very high, that is, the main heat source in the cosmetic instrument is the light emitting component 500.

After the light emitting assembly 500 starts to operate, since the light reflecting assembly 200 is wound outside the light emitting assembly 500, the light reflecting assembly 200 can effectively isolate the light emitted by the light emitting assembly 500, so that most of the light is reflected to a designated direction under the guidance of the light reflecting assembly 200, namely, is reflected to the light guiding block 110, thereby reducing the contact between other structures and the light, avoiding the heat generated by other structures under the irradiation of the light, and reducing the heat productivity of the beauty instrument from the root.

The semiconductor cooling assembly 300 is abutted to the light guide block 110, and can cool and dissipate heat of the light guide block 110 synchronously when the light guide block 110 is irradiated by light to generate heat, so that the light can penetrate through the light guide block 110 and irradiate the skin of a user to stimulate the skin, and the beautifying effect is realized. The light guide block 110 is cooled by the semiconductor cooling assembly 300, so that the temperature of the light guide block 110 is kept appropriate, the light guide block 110 is convenient to be attached to the skin of a user, the use experience of the user is improved, and meanwhile, the beauty instrument can be continuously used without worrying about heating.

Furthermore, the light reflecting component 200 and the semiconductor cooling component 300 are both disposed in the cooling channel 120, and the cooling air flowing in the cooling channel 120 can continuously exchange heat between the light reflecting component 200 and the semiconductor cooling component 300, cool and dissipate heat, so as to improve the heat dissipation capability of the heat dissipation structure of the beauty instrument of the embodiment. When cooling air flows through the cooling channel 120, the cooling air can also flow through the light emitting module 500 and the light guide block 110, and thus, the cooling air is matched with the light reflecting module 200 and the semiconductor cooling module 300 to cool and dissipate heat, so that the heat dissipation capacity of the embodiment is improved.

It should be noted that, the light emitting component 500 in the beauty instrument is generally configured as a tungsten filament lamp, and the tungsten filament lamp can emit milk light, i.e. light with a near infrared spectrum (peak 1300 nm) of 900-1800mm, and such light acts on water in the middle-deep dermis of the skin. When the surface layer of water is irradiated with milk, the distance between each water molecule increases, making the liquid "more fluid". Mitochondria are energized by an enzyme that binds to their cell membrane. The enzyme rotates like a molecular turbine, and being surrounded by more fluid water can make it easier to turn, thereby producing more ATP.

ATP (adenosine triphosphate) promote the repair and regeneration of organism cells, ATP, adenosine triphosphate, belongs to a coenzyme, is a direct source of energy required by all vital activities of tissue cells in the body, can promote the repair and regeneration of cells in the body, promote the enhancement of the bioactivity of collagen fibers, redistribute dermis layers, repair damaged skin and enable the skin to be an excellent reflector, thereby indirectly increasing the refractive index of the surface of the skin, and further enabling the skin to whiten and tender.

The photothermal effect promotes pigment metabolism and decomposition, the photothermal effect generated by milk light can enhance blood vessel function, expand micro blood vessels, accelerate blood circulation, increase oxygen content of blood, accelerate metabolite removal, and realize cosmetic effect by the way.

In one embodiment, as shown in fig. 6 and 7, the light reflecting component 200 includes a first light reflecting member 210 and a second light reflecting member 220, wherein the first light reflecting member 210 is wound around the outside of the light emitting component 500, and an opening is provided on the first light reflecting member 210; the second light reflecting member 220 is disposed at the opening of the first light reflecting member 210. The first reflecting member 210 is disposed outside the light emitting assembly 500, so that the light generated by the light emitting assembly 500 can be prevented from being irradiated onto other structures, which results in heating of the main body of the beauty instrument. In addition, be provided with the opening on the first reflection of light piece 210 to be provided with the second reflection of light piece 220 in the opening part, can pass through first reflection of light piece 210, the cooperation of second reflection of light piece 220, lead the light that luminous subassembly 500 produced to appointed direction, when realizing the cooling function, can also concentrate the light that luminous subassembly 500 produced, improve the result of use of beauty instrument.

In one embodiment, as illustrated in fig. 6 and 7, the first light reflecting member 210 is provided in a semi-cylindrical shape, and an axis of the first light reflecting member 210 coincides with an axis of the light emitting assembly 500. The coaxiality of the first reflecting piece 210 and the light emitting assembly 500 is controlled, so that the direction of the first reflecting piece 210 to the light generated by the light emitting assembly 500 can be controlled, the first reflecting piece 210 and the light emitting assembly 500 are coaxially arranged, the light generated by the light emitting assembly 500 can be uniformly reflected, and the light is emitted from the opening of the first reflecting piece 210.

In one embodiment, as shown in fig. 6 and 7, the second light reflecting member 220 is illustratively provided in a cylindrical shape, an end of the second light reflecting member 220 abuts against the opening of the first light reflecting member 210, and an end of the second light reflecting member 220 far from the first light reflecting member 210 abuts against the light guiding block 110. The light emitted from the first light reflecting member 210 may enter the second light reflecting member 220, the second light reflecting member 220 is configured in a cylindrical shape, and the light entering the second light reflecting member 220 may be guided by the second light reflecting member 220 to be emitted into the light guiding block 110 and emitted from the light guiding block 110. Thus, the light is effectively prevented from leaking to the outside of the second reflecting member 220, not only the heating of the external structure can be avoided, but also the light can be concentrated, and the beautifying effect is ensured.

It can be appreciated that, in actual production, the first light reflecting member 210 and the second light reflecting member 220 can be set to any shape according to the actual shape of the light emitting assembly 500 and the condition of the internal space of the beauty treatment apparatus, so long as the light generated by the light emitting assembly 500 can be prevented from leaking and the light generated by the light emitting assembly 500 can be guided. In the present embodiment, the first light reflecting member 210 is configured to be semi-cylindrical, and the second light reflecting member 220 is configured to be cylindrical, so that the processing is facilitated, and the production cost is reduced.

In one embodiment, the first and second reflectors 210 and 220 are each provided with a reflective coating inside, for example. The reflective coating is arranged in the first reflective member 210 and the second reflective member 220, so that the reflective capability of the inner walls of the first reflective member 210 and the second reflective member 220 to light is improved, the light is prevented from directly passing through the inner walls and irradiating the external structure, and meanwhile, the light can be guided through the reflective capability, so that the light is irradiated to the target position. The reflective coating can be selected, and materials with different materials can be flexibly selected as the reflective coating according to different light rays. In the embodiment, aiming at milk light with the wavelength of 900-1800mm, the aluminum-based silver-plated reflecting film is selected as the reflecting coating, so that the optical efficiency of light reflected on the reflecting surface each time can be improved, and the heat generation is reduced.

It is worth mentioning that the efficacy of skin care is mainly determined by the energy density, and the greater the energy density, the better the effect within the safe range of values. The energy density is affected by the energy and the spot size, the larger the energy density, and the smaller the spot size, the larger the energy density. Therefore, the embodiment of changing the energy density is to change the intensity of the energy and the size of the light spot area, and the reduction of the size of the opening of the light reflecting component 200 is the most important change on the premise of ensuring the heat dissipation capability of the light guiding component. The minimum limit value of the spot size is the cross-sectional size of the reflector 200 tangential to the outer diameter of the lamp tube by the reflection of the light by the reflector 200, and such light can pass through the light guide to act on the skin, thereby improving the cosmetic effect of the present embodiment.

In one embodiment, as illustrated in fig. 4-6, the semiconductor cooling assembly 300 includes a TEC cooling plate 310 and a liquid cooling module, where the TEC cooling plate 310 is attached to the light guide block 110, and the liquid cooling module is capable of cooling the TEC. The TEC cooling plate 310, i.e. the semiconductor cooling plate, is characterized in that when the TEC cooling plate 310 works, one side surface refrigerates, and the other side surface heats. In this embodiment, the side surface cooled by the TEC cooling plate 310 is attached to the light guide block 110, and the liquid cooling module cools and dissipates heat to the side surface heated by the TEC cooling plate 310. Like this, through TEC refrigeration piece 310, make light guide block 110 keep suitable temperature, when the user is in use, can directly laminate light guide block 110 on skin, improve the cooling heat dissipation ability of this embodiment, and then improve the use experience of beauty instrument.

It should be noted that the cooling capacity of the TEC cooling plate 310 is affected by the supply voltage, i.e., the greater the voltage supplied to the TEC cooling plate 310, the greater the cooling capacity of the TEC cooling plate 310. On this basis, in this embodiment, a control element can be further provided, and the voltage of the TEC refrigerating plate 310 is controlled by the control element, so that when the temperature of the light guide block 110 is high, the voltage is increased, the refrigerating capacity of the TEC refrigerating plate 310 is improved, and otherwise, the voltage is reduced. Through the control to TEC refrigeration piece 310 for light guide block 110 can keep at suitable temperature, further improves the heat dispersion of this embodiment, improves the use experience of beauty instrument.

It should be noted that, the heat dissipation effect of the heated surface of the TEC refrigeration sheet 310 will affect the refrigeration effect of the refrigerated side surface in a reverse way, in this embodiment, since the heat dissipation structure of the tungsten filament lamp tube is disposed adjacent to the TEC refrigeration sheet 310, in order to prevent the heat generated by the heat dissipation of the tungsten filament lamp tube from interfering with the heat dissipation effect of the TEC refrigeration sheet 310, the heat dissipation structure and the heat dissipation structure are separated by a space isolation and heat insulation way, so that they are not affected each other, and each run, thereby ensuring that the sapphire contacted with the skin of the user obtains a good refrigeration effect.

Thus, when the liquid cooling pipeline 330 passes through the TEC refrigerating piece 310, heat exchange is performed on the heat generating part of the TEC refrigerating piece 310, the temperature of the liquid cooling pipeline 330 is low, and the temperature of the TEC refrigerating piece 310 is absorbed to cool the same. When the liquid cooling pipe 330 passes through the heat dissipating member 320, the heat dissipating member 320 dissipates heat of the warmed liquid cooling pipe 330, so as to dissipate heat carried by the fluid in the liquid cooling pipe 330 after flowing through the TEC cooling plate 310. By repeating the cycle, the TEC cooling fin 310 is cooled and dissipated.

It is understood that the heat sink 320 may be configured in any structure as long as the liquid cooling pipe 330 can be cooled. Illustratively, the heat sink 320 is configured as a heat sink fin, such that when the liquid cooling tube 330 contacts the heat sink fin, heat is transferred from the liquid cooling tube 330 to the heat sink fin, which has a larger surface area and dissipates heat faster, thereby providing a heat dissipation effect. Furthermore, the heat dissipation fins are also arranged in the cooling channel 120, and cooling air flowing in the cooling channel 120 is matched with the larger surface area of the heat dissipation fins, so that the heat dissipation fins can dissipate heat rapidly.

In one embodiment, the liquid cooling conduit 330 is illustratively provided with a power member capable of driving a liquid cooling medium along the liquid cooling conduit 330. The liquid cooling medium is driven to flow along the liquid cooling pipeline 330 through the power piece, so that the heat dissipation capacity of the liquid cooling pipeline 330 is improved. The power piece can be set as a water pump, so that the flow speed of the liquid cooling medium is improved, the heat dissipation capacity is improved, and the operation is stable and reliable.
