Description

Technical Field

[0001] This invention relates to a nail art device, and more specifically to a nail art phototherapy device with zoned light sources and easy disassembly and maintenance. Background Technology

[0002] The UV curing device is the core equipment for professional nail art, specifically designed for the rapid curing of various UV gels. It utilizes the special wavelengths of UV or LED light sources to activate the photosensitive components within the gel, causing the gel to complete the curing reaction in a short time, forming a hard and wear-resistant nail surface. This instant curing function not only creates a long-lasting and glossy nail effect but also enables multi-layer layering techniques. For example, when creating gradient nail art, each layer can be precisely cured to ensure a natural color transition without mixing.

[0003] Most mainstream nail gel lamps on the market rely on LED light sources for their core curing function. The specific wavelength of blue-violet light emitted by the LED light source is essential for triggering the curing of the gel. Compared to traditional UV light sources, LED light sources significantly improve the curing speed of the gel. LED light sources are generally fixedly installed inside the gel chamber of the nail gel lamp. For example, Chinese Patent CN206166101U discloses an LED nail gel lamp that includes a base plate and a molded inner shell. The rear and side edges of the inner shell are respectively connected and fixed to the base plate, and the front edge of the inner shell is bent and open to the base plate. The inner shell is designed in an open shape. An outer cover is fitted onto the outer surface of the inner shell. The outer cover has a control main board, an operation panel, and a DC power interface. The inner shell has several LED substrates. The operation panel, the LED substrates, and the DC power interface are electrically connected to the control main board. The LED substrates are symmetrically arranged between the inner shell and the outer cover about the horizontal central axis of the inner shell. The LED substrates are fixedly connected to the inner shell. The inner shell has several sets of light-transmitting and reflecting holes that cooperate with the LED substrates. Each LED substrate has two or more sets of LED light sources, and the wavelengths of each set of LED light sources on any LED substrate are different.

[0004] The LED light source in the above technical solution is fixed to the inner shell by an LED substrate. The applicant found that this design has the following defects: Since the LED light sources share the same physical substrate, when any LED light source fails due to aging, overload or broken solder joints, the LED substrate circuit may form a partial open circuit or abnormal current distribution, causing undamaged adjacent LED light sources to also decay faster due to current overload. Furthermore, the rigid fixing design of the LED substrate and the inner shell means that the large inner shell must be removed from the base plate for maintenance, which not only increases the difficulty of maintenance, but also makes the large inner shell and base plate prone to damage during repeated disassembly and assembly. Summary of the Invention

[0005] To address the above issues, and to overcome the problem that current nail light source devices use LED substrates to fix the LED light source onto the inner shell of the nail light therapy device, requiring the large inner shell to be disassembled from the base plate for maintenance, which not only increases the difficulty of maintenance but also easily causes damage to the large inner shell and base plate during repeated disassembly and assembly, the purpose of this utility model is to provide a nail light therapy device where the LED light source is separately integrated onto multiple LED substrates, achieving a partitioned design, and multiple installation areas are set on the inner wall of the light therapy chamber for independent installation. This allows for convenient and targeted maintenance when the LED light source fails, reducing maintenance difficulty and minimizing damage to other components caused by repeated disassembly and assembly.

[0008] Preferably, a limiting protrusion is formed sequentially on the side wall of the substrate mounting area, and a limiting groove is formed between the limiting protrusion and the bottom wall of the substrate mounting area, and the LED substrate is embedded in the limiting groove through the side edge.

[0009] Preferably, a positioning cavity is formed on one side wall of the substrate mounting area, and a snap-fit ​​portion is formed on the other opposite side wall.

[0010] Preferably, the snap-fit ​​part includes a snap-fit ​​cavity, in which a support plate is formed.

The upper snap fastener is L-shaped and engages with the support plate.

[0011] Preferably, the phototherapy chamber includes an inner wall comprising a transverse sidewall, an oblique sidewall, a longitudinal sidewall, and a top wall. The oblique sidewall and the longitudinal sidewall each have two sets. The two sets of oblique sidewalls are located on the left and right sides of the transverse sidewall and are respectively connected to the two sets of longitudinal sidewalls. An opening is formed between the two sets of longitudinal sidewalls. The top wall is located at the top of the transverse sidewall, the oblique sidewall, and the longitudinal sidewall.

[0012] Preferably, the height of the transverse sidewall, the oblique sidewall, and the longitudinal sidewall is 7.2 cm, the angle between the oblique sidewall and the transverse sidewall is 130°, and the angle between the oblique sidewall and the adjacent longitudinal sidewall is 140°.

[0013] Preferably, heat dissipation holes are provided in the substrate mounting area.

[0014] Preferably, the surface of the light guide plate is coated with a chrome plating.

[0015] Preferably, the electronic control assembly includes a control circuit board, a battery, a charging interface, a power switch, a timer switch, and a display panel.

[0020] Compared with the prior art, the advantages of the present invention are as follows:

[0021] This invention integrates LED light sources separately onto multiple LED substrates, thereby allowing for zoned adjustment of the LED light source 301. Each LED substrate and its corresponding light guide plate are detachably connected to the substrate mounting area. Even if the LED light source on the LED substrate fails, the LED substrate can be independently removed from the substrate mounting area for targeted maintenance after the light guide plate is removed, thus protecting the other LED substrates that are still functioning normally from being affected. This not only reduces maintenance difficulty and improves maintenance efficiency but also reduces damage to other components caused by repeated disassembly and reassembly, extending the overall service life of the equipment.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0038] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the purpose of simplifying the description and do not indicate or imply that the orientation is a specific orientation or specific orientation structure and operation. Therefore, they should not be construed as limiting this utility model.

[0039] like Figure 1 and Figure 3As shown, this utility model relates to a nail phototherapy device with zoned light sources and easy disassembly and maintenance. It includes a housing 1, with a phototherapy chamber 101 at the front for placing the palm. An electronic control assembly 2 is located inside the housing 1. Each side wall of the phototherapy chamber 101 has a substrate mounting area 102. LED substrates 3 and light guide plates 4 are detachably mounted sequentially from the outside to the inside of each substrate mounting area 102. The substrate mounting area 102 is closed by the mounted light guide plate 4, and each substrate mounting area 102 is connected to the interior of the housing 1 for wiring. Multiple LED light sources 301 are arranged evenly on their corresponding LED substrates 3. The LED substrates 3 are electrically connected to the electronic control assembly 2 to control the illumination of the LED light sources 301. Light-transmitting holes 401 are opened on the light guide plate 4, opposite to the LED light sources 301. The LED light sources 301 emit near-ultraviolet light with a wavelength of 395-405nm. The light is projected into the phototherapy chamber 101 through the light-transmitting hole 401. The near-ultraviolet light of this wavelength can precisely match the wavelength required for the curing of the phototherapy adhesive, which significantly improves the curing speed of the phototherapy adhesive. The cold light source characteristics of the LED light source 301 can also avoid the high temperature burning sensation during the curing process, increasing the comfort and safety of the palm. At the same time, the lifespan of the light source is relatively longer. In addition, this utility model integrates the LED light source 301 separately on multiple LED substrates 3, thereby adjusting the LED light source 301 in sections. Each LED substrate 3 and the corresponding light guide plate 4 are detachably connected to the substrate mounting area 102. Even if the LED light source 301 on the LED substrate 3 fails, the LED substrate 3 can be independently removed from the substrate mounting area 102 for targeted maintenance after removing the light guide plate 4, so that the other LED substrates 3 that can work normally are not affected. This not only reduces the maintenance difficulty and improves the maintenance efficiency, but also reduces the damage to other components caused by repeated disassembly and reassembly, and extends the overall service life of the equipment.

[0040] like Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, a limiting protrusion 102a is formed on the side wall of the substrate mounting area 102. There is a gap between the limiting protrusion 102a and the bottom wall of the substrate mounting area 102, which forms a limiting groove 102b. The LED substrate 3 is embedded in the limiting groove 102b through the side edge, thereby being accurately installed in the substrate mounting area 102. At the same time, it is easy to disassemble and is firmly fixed with the light guide plate 4. In other words, the LED substrate 3 ensures installation stability through the above-mentioned double limiting and facilitates subsequent disassembly and maintenance.

[0041] like Figures 4 to 7 as well as Figure 9As shown, a positioning cavity 103 is formed on one side wall of the substrate mounting area 102, and a snap-fit ​​portion 104 is formed on the other opposite side wall. A positioning block 402 corresponding to the positioning cavity 103 and a snap fastener 403 corresponding to the snap-fit ​​portion 104 are formed on the light guide plate 4. The positioning block 402 is inserted into the positioning cavity 103, allowing the positioning block 402 to rotate within the positioning cavity 103 in the engaged state. The snap fastener 403 engages with the snap-fit ​​portion 104. During installation, the positioning block 402 of the light guide plate 4 is first inserted into the positioning cavity 103 to form a rotation fulcrum, and then... Rotating the light guide plate 4 afterwards allows the buckle 403 and the latching part 104 to be securely engaged. After installation, the positioning cavity 103 and the positioning block 402, as well as the latching part 104 and the buckle 403, will generate two positioning points, thus securing the light guide plate 4. When disassembling, the light guide plate 4 is rotated in the opposite direction with the positioning cavity 103 as the fulcrum. First, the buckle 403 and the latching part 104 are released from their engagement state, and then the light guide plate 4 can be easily removed by moving it along the opening direction of the positioning cavity 103. In other words, disassembly and assembly can be completed in two steps, greatly improving the convenience of subsequent maintenance.

[0042] like Figure 6 , Figure 7 , Figure 9 As shown, the snap-fit ​​part includes a snap-fit ​​cavity, within which a support plate is formed. The support plate 104b is horizontally placed within the snap-fit ​​cavity 104a, dividing the snap-fit ​​cavity 104a into upper and lower cavities. The width of the snap fastener 403 is smaller than that of the snap-fit ​​cavity 104a, and it is embedded within the snap-fit ​​cavity 104a. The snap fastener 403 consists of an upper snap fastener 403a and a lower snap fastener 403b, both of which are embedded within the snap-fit ​​cavity 104a. More specifically, the snap-fit ​​cavities 104a, located on the upper and lower sides of the support plate 104b respectively, are engaged by snap-fit... Cavity 104a restricts the axial movement of buckle 403. The upper buckle body 403a is L-shaped and engages with the support plate 104b. The width of buckle 403 is smaller than that of the engagement cavity 104a, allowing buckle 403 to move radially within the engagement cavity 104a. Thus, when it is necessary to disassemble the light guide plate 4, buckle 403 can be pressed to move the lower buckle body 403b along the engagement cavity 104a until the upper buckle body 403a disengages from the support plate 104b. Then, the light guide plate 4 can be rotated with the positioning block 402 and the positioning cavity 103 as the fulcrum to disassemble smoothly.

[0043] like Figure 10As shown, the phototherapy chamber 101 adopts an ergonomic design. Its inner wall consists of a transverse side wall 101a, an oblique side wall 101b, a longitudinal side wall 101c, and a top wall 101d. There are two sets of oblique side walls 101b and longitudinal side walls 101c. The two sets of oblique side walls 101b are located on the left and right sides of the transverse side wall 101a and are connected to the two sets of longitudinal side walls 101c respectively. An opening is formed between the two sets of longitudinal side walls 101c. The top wall 101d is located at the top of the transverse side wall 101a, oblique side wall 101b, and longitudinal side wall 101c. That is to say, the oblique side wall 101b forms an angle with the transverse side wall 101a and the connected longitudinal side wall 101c, so that the phototherapy chamber 101 presents a progressively converging shape, thereby matching the characteristics of the palm. When the palm is placed into the phototherapy chamber 101 through the opening, it can obtain a good sense of envelopment, significantly improving the comfort of use and the phototherapy effect.

[0044] like Figure 10 and Figure 11 As shown, the height of the transverse sidewall 101a, the oblique sidewall 101b, and the longitudinal sidewall 101c is 7.2cm, ensuring sufficient space for phototherapy even when the palm is arched. The angle between the oblique sidewall 101b and the transverse sidewall 101a is 130°, and the angle between the oblique sidewall 101b and the adjacent longitudinal sidewall 101c is 140°, giving the phototherapy chamber 101 a progressively converging shape that matches the characteristics of the palm and ensures that the optimal gap is maintained between the palm and the inner wall during treatment.

[0045] like Figure 3 and Figure 6 As shown, heat dissipation holes 102c are provided in the substrate mounting area 102. The heat dissipation holes 102c are mainly used for the rapid diffusion of heat conducted by the LED substrate 3. The heat dissipation holes 102c form a convection channel to enhance air flow efficiency and improve heat dissipation effect.

[0046] Furthermore, the surface of the light guide plate 4 is coated with a chrome plating, so that when the near-ultraviolet light emitted by the LED light source 301 is projected onto the light guide plate 4, a mirror reflection effect will be formed, avoiding the diffuse scattering loss of near-ultraviolet light, ensuring the efficient transmission of phototherapy energy, and further improving the phototherapy curing effect.

[0047] like Figure 1 , Figure 2 and Figure 12As shown, the electronic control assembly 2 includes a control circuit board 201, a battery 202, a charging interface 203, a power switch 204, a timer switch 205, and a display panel 206. The charging interface 203, power switch 204, timer switch 205, and display panel 206 are fixed to the outer wall of the housing 1. A battery compartment 107 is provided on the outer wall of the housing 1, and the battery 202 is embedded in the battery compartment 107. A battery cover 5 is provided on the battery compartment 107. The battery 202 can be removed by removing the battery cover 5 for easy replacement. The battery cover 5 protects the battery 202. The battery 202, charging interface 203, and power switch 204 are electrically connected to the control circuit board 201. The timer switch 205 and display panel 206 are integrated into the control circuit board 201. The control circuit board 201 has a wiring port 102d in the substrate mounting area 102. The wiring harness of the LED substrate 3 is electrically connected to the control circuit board 201 through the wiring port 102d to achieve hidden wiring. The user can operate the nail phototherapy device of this invention by controlling the power switch 204. After starting, the phototherapy time can be set by the timer switch 205. There are multiple timer switches 205 in this invention, and each timer switch 205 corresponds to a specific phototherapy time. The phototherapy time will be displayed on the display panel 206. The battery 202 supplies power to the entire circuit. The user can charge the battery 202 by connecting the charging interface 203 and the external power source through the data cable. It should be mentioned that phototherapy curing can still be performed while charging.

[0048] like Figure 12 As shown, the housing 1 includes an upper housing 105 and a lower housing 106. The upper housing 105 covers the top of the lower housing 106 and is fixed by threaded fasteners. The phototherapy chamber 101 is located at the front of the lower housing 106. The control circuit board 201, the battery 202, the charging interface 203, and the power switch 204 are located on the lower housing 106. The timer switch 205 and the display panel 206 are located on the upper housing 105. The upper housing 105 and the lower housing 106 can protect the control circuit board 201, the battery 202, the charging interface 203, the power switch 204, the timer switch 205, and the display panel 206 of the electronic control component 2, thereby improving the service life of the phototherapy device of this utility model.

[0049] like Figure 1 and Figure 3 As shown, it also includes a base plate 6 and a cover plate 7. The cover plate 7 is made of metal. The base plate 6 is detachably connected to the bottom of the housing 1. The cover plate 7 is placed on the base plate 6 and is bonded and fixed to the base plate 6. During the phototherapy curing process, the hand is placed on the cover plate, and the rigid cover plate 7 will provide good support for the hand.

[0050] Furthermore, magnets 9 are sequentially provided on the top of the base plate 6, and positioning screws 10 are correspondingly provided on the bottom of the housing 1. The surface of the positioning screws 10 is nickel-plated, so they can be attracted to each other with the corresponding magnets 9. The magnetic fixation method can complete the disassembly and assembly of the base plate without complicated tools or operating steps. Moreover, the magnets are stable and can be repeatedly attracted and separated from the positioning screws without affecting the fixing effect. Furthermore, the mutual attraction between multiple magnets 9 and corresponding positioning screws 10 can significantly improve the fixing effect between the base plate 6 and the housing 1.

[0051] Furthermore, both the bottom of the base plate 6 and the bottom of the housing 1 are provided with anti-slip pads 8 in sequence. There are multiple anti-slip pads 8. Each anti-slip pad 8 can increase the stability of the nail phototherapy device when it is placed, play an anti-slip role, and thus improve the phototherapy curing effect.

[0052] Combination Figures 1 to 13 When using this nail phototherapy device, the user first needs to control the power switch 204 of the electronic control component 2 to make it run. Then, the phototherapy time needs to be set through the timer switch 205. The phototherapy time will be displayed on the display panel 206. The battery 202 supplies power to the entire circuit. When its power is depleted, it can be charged by connecting to an external power source using a data cable. After the phototherapy time is set, the control circuit board 201 controls the LED light source 301 on the LED substrate 3 in the phototherapy chamber 101 to light up. The near-ultraviolet light emitted by the LED light source 301 is projected into the phototherapy chamber 101 through the light-transmitting hole 401 on the light guide plate 4. The chrome-plated coating on the surface of the light guide plate 4 can form a mirror reflection effect in the phototherapy chamber 101, avoiding the diffuse scattering loss of near-ultraviolet light and ensuring efficient transmission of phototherapy energy. At this time, the palm is placed in the phototherapy chamber 101 and supported by the base plate 6. The silicone pad provides good comfort for the hand, presenting a progressively converging shape. The treatment chamber 101 provides a better sense of envelopment for the palm, significantly improving user comfort and phototherapy effect. If any LED light source 301 on the LED substrate 3 fails, the buckle 403 of the light guide plate 4 can be pressed and moved along the locking cavity 104a to disengage the upper buckle 403a from the locking state of the support plate 104b. Then, the light guide plate 4 can be rotated with the docking position of its positioning block 402 and the positioning cavity 103 as the fulcrum. During the rotation, the buckle 403 can separate from the locking part 104, releasing the locking state. The light guide plate 4 can then be easily removed by moving it along the opening direction of the positioning cavity 103. The light guide plate 4 can be disassembled in two steps. After that, the corresponding LED substrate 3 can be moved to disengage it from the limiting slot 102b and removed from the substrate mounting area 102 for maintenance. This not only reduces the difficulty of maintenance and improves maintenance efficiency, but also reduces damage to other components caused by repeated disassembly and reassembly, extending the overall service life of the equipment.

[0053] The embodiments and descriptions above are merely illustrative of the principles and preferred embodiments of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
