[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-3 This utility model provides a technical solution: a nail light therapy lamp, including a bottom shell 1, a top cover 2 on the top of the bottom shell 1, an isolation plate 3 in the middle of the inner cavity of the bottom shell 1, four isolation plates 3, a plurality of first mounting holes 4 are opened on the top surface of the inner cavity of the bottom shell 1 between two adjacent isolation plates 3, and a first ultraviolet lamp bead 5 is arranged in the inner cavity of each first mounting hole 4. A plurality of third mounting holes 13 are opened on both sides of the inner cavity of the bottom shell 1 near the two ends, and a second ultraviolet lamp bead 14 is arranged in the inner cavity of each third mounting hole 13. An MCU controller 6 is arranged on one side of the inner cavity of the bottom shell 1, and three first through holes 7 are opened on one side of the top surface of the top cover 2. A control button 8 is arranged in the inner cavity of each first through hole 7, and the bottom end of the control button 8 is connected to the MCU controller 6. A hand support assembly 10 is arranged at the bottom of the bottom shell 1.
[0023] The bottom shell 1 provides a mounting base for the top cover 2, four isolation plates 3, and MCU controller 6, and also provides space for multiple first mounting holes 4, multiple third mounting holes 13, and three first through holes 7. Since each first mounting hole 4 has a first ultraviolet lamp 5 inside, and multiple third mounting holes 13 are provided on both sides of the inner cavity of the bottom shell 1 near the ends, and each third mounting hole 13 has a second ultraviolet lamp 14 inside, when the fingernails need to be irradiated, the user first places their hand on the hand support assembly 10 with their fingers spread apart. At the same time, through the cooperation of the control button 8 and the MCU controller 6, the user can flexibly turn on the second ultraviolet lamp 14 and the first ultraviolet lamp 5 on the left or right side depending on whether the user has left or right hand. Then, the multiple isolation plates 3 separate the light areas of each finger, thereby avoiding excessive light leakage from each area to the finger skin. The hand support assembly 10 provides support for the bottom shell 1 and makes it convenient for the user to place their fingers.
[0024] See Figure 3 The bottom surface of the bottom shell 1 is provided with a plurality of second mounting holes 11, and each second mounting hole 11 is provided with a magnet block 12 in its inner cavity, and the magnet block 12 is magnetically connected to the handle assembly 10.
[0025] The magnet 12 inside the second mounting hole 11 can be magnetically connected to the handle assembly 10, thereby facilitating the user to disassemble and separate the handle assembly 10 and the bottom shell 1.
[0026] See Figure 1 , Figure 3 and Figure 4 The hand support assembly 10 includes a magnetic finger support plate 101, which is magnetically connected to a magnet block 12. The magnetic finger support plate 101 has multiple finger slots 102.
[0027] The magnetic finger support plate 101 in the hand support assembly 10 can sit stably in the designated position and can be connected to the magnet block 12, so that the magnetic finger support plate 101 can be stably attached to the bottom shell 1. Through multiple finger grooves 102, users can easily find the position of each finger separately, and thus easily irradiate the fingers.
[0028] See Figure 2 A battery 9 is installed on one side of the inner cavity of the bottom shell 1, and the battery 9 is electrically connected to the MCU controller 6. Through the battery 9, the device can be powered by the MCU controller 6, thereby improving the device's battery life.
[0029] See Figure 3 A charging port is embedded in one side wall of the top cover 2. The charging port is electrically connected to the MCU controller 6. An external power supply can be connected through the MCU controller 6, so that the battery 9 can be charged through the MCU controller 6.
[0030] See Figure 3 A control switch 15 is embedded on one side of the top cover 2. The control switch 15 is electrically connected to the MCU controller 6. The operation of the MCU controller 6 can be flexibly turned on or off through the control switch 15.
[0031] See Figure 3 The bottom surface of the bottom shell 1 has multiple stepped holes 16, and each stepped hole 16 has a mounting screw 17 inserted into its inner cavity. The top of the mounting screw 17 is rotatably connected to the top cover 2. Through multiple mounting screws 17, the bottom shell 1 and the top cover 2 can be smoothly and firmly connected together, thereby preventing them from separating.
[0032] During operation, the bottom shell 1 provides a mounting base for the top cover 2, four isolation plates 3, and MCU controller 6, and also provides space for multiple first mounting holes 4, multiple third mounting holes 13, and three first through holes 7. Since each first mounting hole 4 has a first ultraviolet lamp 5 inside, and multiple third mounting holes 13 are provided on both sides of the inner cavity of the bottom shell 1 near the ends, and each third mounting hole 13 has a second ultraviolet lamp 14 inside, when it is necessary to irradiate the fingernails, the user first places their hand on the hand support assembly 10 with their fingers spread apart. At the same time, through the cooperation of the control button 8 and the MCU controller 6, the user can flexibly turn on the second ultraviolet lamp 14 and the first ultraviolet lamp 5 on the left or right side depending on whether the user has left or right hand. Then, the multiple isolation plates 3 separate the light areas of each finger, thereby avoiding excessive light leakage from each area to the finger skin. The hand support assembly 10 provides support for the bottom shell 1 and makes it convenient for the user to place their fingers.
[0033] The magnet 12 inside the second mounting hole 11 can be magnetically connected to the handle assembly 10, thereby facilitating the user to disassemble and separate the handle assembly 10 and the bottom shell 1.
[0034] The magnetic finger support plate 101 in the hand support assembly 10 can sit stably in the designated position and can be connected to the magnet block 12, so that the magnetic finger support plate 101 can be stably attached to the bottom shell 1. Through multiple finger grooves 102, users can easily find the position of each finger separately, and thus easily irradiate the fingers.
[0035] The device can be powered by the MCU controller 6 via the battery 9, thereby improving the device's battery life. The MCU controller 6 can be connected to an external power source, allowing it to charge the battery 9. The MCU controller 6 can be flexibly turned on or off via the control switch 15. The bottom shell 1 and the top cover 2 can be smoothly and securely connected together via multiple mounting screws 17, thus preventing them from separating.
[0036] In summary, the device uses multiple isolation plates 3 to separate the finger light areas, thereby preventing excessive cross-contamination of ultraviolet light from each area onto the finger skin.
[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
