DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(6) With reference to the drawings and in particular to FIGS. 1 to 3, a light solidifying device in accordance with the present invention comprises a body 1, a magnetic slide cover unit 2, a control unit 3, and a light solidifying unit 4. The body 1 has an outer case 11 having a first opening 110. A slide slot 111 is defined around the first opening 110 of the body 1 and points toward the first opening 110. The outer case 11 further has an engaging slot 112. An inner case 12 is a polygonal case and is disposed in the outer case 11. The inner case 12 has a second opening 120 and an inclined sidewall 121. The inclined sidewall 121 of the inner case 12 is arranged to face to the finger nails, especially to the thumb nail, in a direction perpendicular to the inclined sidewall 121. A base 13 has multiple pads 131 connected thereto, and the outer case 11 and the inner case 12 are mounted to the base 13.

(7) The magnetic slide cover unit 2 has a top part 21 with a ridge 211 which is engaged with the engaging slot 112 of the outer case 11. The top part 21 has a reception slot 210. The magnetic slide cover unit 2 further has a slide cover 22 which has a third opening 220. The slide cover 22 has a boss 221 which is a cylindrical member and engaged with the slide slot 111 of the outer case 11. The boss 221 is connected to a fixing member 222 which positions the boss 221, so that the boss 221 is not disengaged from the slide slot 111. The slide cover 22 is slidably movable toward the first opening 110 of the outer case 11 by moving the boss 221 along the slide slot 111. The slide cover 22 has a first magnetic member 223 and the outer case 11 has two second magnetic member 224 which respectively are located at both ends of the outer case 11 parallel to the slide slot 111 and corresponding to the first magnetic member 223. The first magnetic member 223 contacts the reception slot 210 of the top part 21 when the slide cover 22 moves to a top end of the slide slot 111. The first magnetic member 223 is a magnetic metal and the second magnetic member 224 is a magnet which can attract the first magnetic member 223. The third opening 220 of the slide cover 22 is located corresponding to the first opening 110 of the outer case 11 and the second opening 120 of the inner case 12.

(8) The control unit 3 is connected to the body 1 and has a receptacle 30, a circuit board 32 and a control member 31 connected to the circuit board 32. The control member 31 is a button and is exposed out from the outer case 11.

(9) The light solidifying unit 4 is disposed in the body 1 and has a light emitting diode module 41. The light emitting diode module 41 includes a heat dissipating member 42 and a light emitting diode (LED) 40 located in opposite to the heat dissipating member 42 and connected to the wall of the inner case 12, so that the LED 40 irradiates an interior of the inner case 12. The light solidifying unit 4, the receptacle 30 of the control unit 3 and the circuit board 32 are electrically connected.

(10) As shown in FIG. 4, when in use, a user's hand 9 with liquid gel coated on the nails is inserted into the device via the first and second openings 110, 120 and put on the base 13. The slide cover 22 is then moved downward and masked the first and second openings 110, 120. The third opening 220 of the slide cover 22 is kept opened for the insertion of the user's hand 9. Therefore, the gap between the hand 9 and the third opening 220 is small enough to stop the light rays from escaping out from the device to stimulate the user's eyes and skin. The position of the slide cover 22 can be adjusted according to practical needs. When the slide cover 22 is adjusted to the topmost or the lowermost position, the first magnetic member 223 is attracted by the second magnetic member 224 to position the slide cover 22. The magnetic force is suitable to let the user easily move the slide cover 22, while the slide cover 22 can be positioned at a predetermined place if no external force is applied thereto.

(11) Then, the user can start to operate the control member 31 of the control unit 3 to activate the light emitting diode 40 to proceed with the solidification and sterilization process. The light solidifying device of the present invention has advantages of no solvent vaporization during the solidification cross-linking process, a shorter required solidification time, no ripple or deformed gel formed on the nails, and good solidification performance.

(12) Because the inner case 12 is a polygonal case and the inclined sidewall 121 of the inner case 21 is arranged to face to the finger nails, especially to the thumb nail, in a direction perpendicular to the inclined sidewall 121, each of the finger nails can be fully irradiated by the UV light rays.

(13) Although the present invention has been described with reference to the preferred embodiment thereof, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention which is intended to be defined by the appended claims.
