Description

Technical Field

[0001] This invention relates to the field of nail art equipment technology, and in particular to a nail art phototherapy system with skin care function. Background Technology

[0002] In existing nail art processes, UV lamps are an essential piece of equipment. Traditional UV lamps typically use LED light sources of specific wavelengths (mainly ultraviolet wavelengths, such as 365nm or 405nm) to irradiate nails coated with gel polish, using photoinitiators to quickly cure the gel polish.

[0003] However, existing phototherapy equipment has significant drawbacks. Because ultraviolet (UV) light has high energy, prolonged or frequent exposure to UV light on the hands can easily lead to melanin deposition (commonly known as "black hands"), and in severe cases, can even cause dry skin, aging, and an increased risk of skin diseases. Although some UV-protective gloves are available on the market, these gloves typically block all light, preventing users from enjoying the beneficial light waves (such as red and near-infrared light) that may be present during phototherapy. Furthermore, the light source arrangement of existing phototherapy machines is often relatively simple, making it difficult to simultaneously achieve rapid nail hardening and precise protection or care for non-nail areas of the hands.

[0004] Therefore, there is an urgent need for an intelligent nail phototherapy system that can efficiently cure nails, effectively block harmful ultraviolet rays, and allow cosmetic light to penetrate. Summary of the Invention

Those skilled in the art will understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] Please see Figure 1 and Figure 2 This invention provides a nail phototherapy system with skincare functions. The system mainly includes a phototherapy machine body 10, a light source component 20 disposed inside the phototherapy machine body 10, and a filter component 30 used in conjunction with it.

[0029] The phototherapy machine body 10 includes an outer shell assembly and an inner liner assembly 15 disposed inside the outer shell assembly. The outer shell assembly is formed by fastening an upper cover shell 13 and a base 14 together, which are fixedly connected by fasteners or snaps to form a receiving space with a bottom opening. The inner liner assembly 15 is installed in this receiving space, and its inner surface forms a hemispherical concave structure 12, which defines a light-emitting cavity 11 for accommodating a hand or foot. The edge of the inner liner assembly 15 fits tightly against the front opening edge of the base 14, forming a smooth passage for the hand to enter. The base 14 may also be provided with a magnetic or removable base plate for easy cleaning.

[0030] The light source assembly 20 is distributed along the hemispherical concave structure 12, specifically including a top array module 21 and a side projection module 22.

[0031] The top array module 21 serves as the first light source, emitting wavelengths in the ultraviolet region (e.g., 365nm to 405nm) to provide ultraviolet curing light for the nail area. Mechanically, a flexible circuit board or curved aluminum substrate is provided on the back (i.e., the raised surface) of the inner liner assembly 15, and light-transmitting holes are provided on the inner liner assembly 15 corresponding to the position of each LED bead. The LED beads of the top array module 21 are mounted on the circuit board and positioned corresponding to the light-transmitting holes, allowing light to illuminate the nail surface located at the bottom of the light-emitting cavity 11 vertically or nearly vertically.

[0032] The lateral projection module 22 serves as a second light source, emitting wavelengths in the visible light (such as red light above 600nm) or infrared region to provide wide-angle coverage of the back of the hand with cosmetic lighting. Figure 2 As shown, the side projection module 22 includes at least two high-power lamp heads symmetrically arranged on both sides of the upper inner wall of the illumination cavity 11. Mechanically, the side projection module 22 employs an independent heat dissipation mounting structure, including a metal heat sink bracket 222 and a COB light source plate 223. The metal heat sink bracket 222 is fixedly connected to the outer sides of the two side walls of the base 14 or the inner liner assembly 15 and has a preset tilt angle. This tilt angle is configured so that the optical axis of the COB light source plate 223 points to the central bottom surface of the illumination cavity 11, i.e., the area where the thumb of the hand is usually located. A finned heat dissipation structure is attached to the back of the metal heat sink bracket 222, utilizing the space inside the housing for heat exchange. Furthermore, a condenser cup structure 221 is provided around the lamp heads of the side projection module 22 to further control the beam range, focusing on covering the skin area on the side of the hand.

[0033] The main control circuit board 16 is also installed in the top space inside the main body 10 of the phototherapy machine. The top array module 21 and the side projection module 22 are electrically connected to the main control circuit board 16 through wire harnesses. The main control circuit board 16 integrates a power management and logic control module, which is used to independently control the on / off state and intensity of the ultraviolet light source and the beauty light source according to user instructions.

[0034] II. Optical Performance of Filter Components To complement the aforementioned light source components and achieve the function of "curing nails while simultaneously beautifying and caring for the skin," this system is equipped with a special light filter component 30. The light filter component 30 is made of a specific light filter material that has significant spectral selectivity transmission characteristics.

[0035] Please see Figures 3 to 5 Spectral test diagram and Figures 6 to 8 Physical test image.

[0036] Figure 3 The test data for acrylic sheets as the base material is shown. Without the addition of specific light-filtering factors, the substrate has a transmittance of 86.5% at 365nm, indicating that ordinary transparent materials cannot block harmful ultraviolet rays. Figure 6 and Figure 8 Physical testing further validated this.

[0037] Figure 4 The measured data of the material used in the filter component 30 of this invention are presented. The curves show that the material exhibits extremely high blocking efficiency in the ultraviolet region and extremely high transmittance in the beauty red light region. Specifically, at 365 nm, the transmittance is only 0.5% (e.g., ...). Figure 7The actual test results show a transmittance of 0.3%, effectively blocking harmful ultraviolet rays; at 600nm, the transmittance rapidly increases to 85.3%, and at 940nm, the transmittance reaches as high as 88.8%. This meets the requirements of the filter material having a transmittance of less than 5% for the first light source and a transmittance of more than 50% for the second light source.

[0038] Figure 5 The test results of the component and the acrylic composite structure were shown. The results showed that ultraviolet rays were completely blocked in the UV blocking region (T<1%), while in the band marked as the "effective transmission region of beauty red light", the transmittance remained at a high level of 78.9% to 82.4%.

[0039] III. Specific Forms and Usage of Filter Components Please see Figure 9 In this embodiment, the light-filtering component 30 is manufactured in the form of a phototherapy glove. This phototherapy glove includes a palm portion 31 and finger portions 32. The finger portions 32 correspond to the five fingers of the human body, and each finger portion 32 has a nail exposure opening 33 at its end. The edges of the nail exposure openings 33 are tightened by a strap 34. The strap 34 can be an elastic rubber band or a Velcro structure, used to tightly fit the user's finger base area, preventing ultraviolet light from leaking into the skin through gaps.

[0040] During use, the user places their hand inside the phototherapy glove, with only the nails to be cured exposed through the nail exposure opening 33. When the hand, wearing the filter assembly 30, is placed into the light-emitting cavity 11, the ultraviolet light emitted by the top array module 21 can only reach the exposed nails to cure the nail polish, while the ultraviolet light reaching the skin of the hand is completely blocked by the phototherapy glove. At the same time, the red or infrared light emitted by the side projection module 22 penetrates the glove material and acts on the dermis of the hand, promoting collagen regeneration and achieving skin rejuvenation and anti-wrinkle cosmetic effects.

[0041] In addition, in some embodiments, the surface of the filter component 30 may also be coated with a photocatalytic coating or a fluorescence conversion coating. The fluorescence conversion coating has a wavelength conversion function, capable of absorbing the ultraviolet light emitted from the top array module 21 and exciting it into a visible light band that is beneficial to the skin.

[0042] In summary, this invention, through its unique optical structure design, light source arrangement, and combination of special filter materials, completely solves the problem of UV damage to hands while ensuring nail polish curing efficiency, and innovatively introduces a synchronized phototherapy beauty function.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
