DETAILED DESCRIPTION OF THE INVENTION
With reference to FIGS. 1-7, a lighting eyelash curler according to the present invention includes a main board 1 with left and right sidewalls. A space 15 is defined in a rear end of the main board 1. A circuit board 2 is fixed in the space 15. Two power contacts 21 are provided on a top face of a rear end of the circuit board 2 and respectively connected to the positive and negative poles of a power source 100. Two power output contacts are provided on a front end of the circuit board 2. A U-shaped fence 11 is provided on a front end of the main board 1. A compartment 12 is defined between a left sidewall of the fence 11 and the left sidewall of the main board 1. Another compartment 12 is defined between a right sidewall of the fence 11 and the right sidewall of the main board 1. Light-emitting diodes (LED) 3 are mounted in at least one of the compartments 12 and have two power contacts electrically connected to the power output contacts of the circuit board 2.
A movable clamp 4 is mounted to the front end of the main board 1. The front end of the main board 1 includes a movement hole 18 slideably receiving the movable clamp 4. A rear end of the movable clamp 4 is received in the U-shaped fence 11. Each of the left and right sidewalls of the fence 11 has a support seat 111. A turnover plate 10 is mounted to the support seats 111 and includes a rotating plate 101 at the front, a catch 103 at the rear, and a rotating shaft 102 between the rotating plate 101 and the catch 103. Through-holes are defined in a rear end of the rotating plate 101 and in a front end of the catch 103. An intermediate portion of the rotating shaft 102 is received in the through-holes of the rotating plate 101 and the catch 103. Two ends of the rotating shaft 102 abut with the support seats 111. A catch hole 42 is defined in the rear end of the movable clamp 4 and receives the catch 103.
A fixed clamp 7 is mounted to the front end of the main board 1 and includes a fixing board 71 at the rear, a pressing board 73 at the front, and two links 72 between the fixing board 71 and the pressing board 73. The fixing board 71 of the fixed clamp 7 is fixed to an intermediate portion of an upper face of the main board 1. The links 72 are spaced from each other and each have two ends respectively connected to the fixing board 71 and the pressing board 73. A receiving space defined by the fixing board 71, the links 72, and the pressing board 73 and matches with the front end of the turnover plate 10. An intermediate portion of a lower face of each link 72 includes a first recess 75 and a second recess 74 for matching with the support seats 111 and the light-emitting diodes E. The intermediate portions of the link 72 cover the compartments 12 formed by the left and right sidewalls of the main board 1 and the U-shaped fence 11. A lid 8 and a power source lid 9 are mounted to the upper face of the main board 1. The lid 8 is located in an intermediate portion of the upper face of the main board 1 and engages with the main board 1. The power source lid 9 is located in a rear end of the upper face of the main board 1 and engages with the lid 8.
In use, the power source lid 9 is removed from the rear end of the upper face of the main board 1, and the power source 100 is mounted to the circuit board 2. Thus, the circuit board 2 can control lighting of the light-emitting diodes E on the front end of the lighting eyelash curler. The turnover plate 10 is turned by its front end, pivoting the turnover plate 10 about an axis defined by the rotating shaft 102. The catch 103 at the rear end of the turnover plate 10 pushes the movable clamp 4 to move forward/rearward along the left and right sidewalls of the U-shaped fence 11. When the catch 103 pushes the movable clamp 4 forward so that the front end of the movable clamp 4 is adjacent to the fixing board 71 of the fixed clamp 7, trimming of eyelashes can be carried out. By such an arrangement, eyelash trimming can be done with illumination, avoiding poor trimming in a dark area and, hence, avoiding poor image resulting from poor light.
With reference to FIG. 6, the movable clamp 4 includes a movement groove 41 in an intermediate portion thereof. A guard 16 is formed on an intermediate portion of the movement hole 18. The guard 16 matches with the movement groove 41 and located in the movement hole 41. An elastic element is received in the movement groove 41 and includes a front end abutting against the fence 16 and a rear end abutting against a rear end of the movement groove 41. Through provision of the movement groove 41 and the elastic element, the movable clamp 4 is biased by the elastic element towards the rear end of the U-shaped fence 11. When the turnover plate 10 of the lighting eyelash curler provides no active force, the movable clamp 4 can be reset under the action of the elastic element to retain the lighting eyelash curler in the open state. When operating the lighting eyelash curler, eyelash trimming can be carried out by simply closing the lighting eyelash curler. The operation is more convenient by resetting the movable clamp 4 under the action of the elastic element.
The elastic element is a spring 5 in the form shown. A positioning peg 43 is provided on the rear end of the movement groove 41. The guard 16 includes left and right sidewalls 161 extending therefrom. The front end of the spring 5 is fixed in a compartment defined between the guard 16 and the left and right sidewalls 161. The rear end of the spring 5 is mounted around the positioning peg 43. Use of the spring 5 is convenient and useful. The spring 5 fixed in the movement groove 41 avoids undesired shifting of the spring 5 due to vibration during use. Thus, the movable clamp 4 can be reliably returned.
A groove 44 is defined in the front end of the movable clamp 4 and receives a rubber pad 6. When using the lighting eyelash curler to trim eyelashes, the eyelashes of the human body are located between the front end of the movable clamp 4 and the pressing board 73 of the fixed clamp 7. By mounting the rubber pad 6 on the front end of the movable clamp 4, soft contact can be provided between the eyelashes and the movable clamp 4 to adjust the clamping force between the movable clamp 4 and the fixed clamp 7.
The circuit board 2 includes a switch contact. A mounting hole 191 is defined in the main board 1 or the lid 8. In the form shown, the mounting hole 191 is defined in the main board 1 and receives a button 19 aligned with the switch contact on the circuit board 2. The lower face of the main board 1 can include a pattern corresponding to a shape of the button 19 to provide easy handling and aesthetically pleasing effect. Opening and closing of the circuit can be controlled through the button 19.
The circuit board 2 further includes an IC chip for controlling the lighting patterns of the light-emitting diodes 3.
The rear end of the main board 1 includes a mounting hole 13 receiving another rubber pad 6. The rubber pad 6 is a spare pad for replacement when the rubber pad 6 at the front end of the movable 4 is worn out, avoiding adversely affect to the makeup.
Two engagement blocks 14 are provided in the space 15 and fixed to left and right sidewalls of the main board 1. Each engagement block 14 includes an engagement notch 141 for engagement with the circuit board 2. The circuit board 2 is engaged with the engagement blocks 14. By securely fixing the circuit board 2 in the space 15 with the engagement blocks 14, impingement and damage to the circuit board 2 during use of the lighting eyelash curler can be avoided.
A connecting board 76 is connected between the links 72 and includes an intermediate portion fixed to the front end of the main board 1. The connecting board 76 reinforces the relative fixed position between the links 72. Furthermore, the connecting board 76 fix the fixed clamp 7 to the main board 1, preventing loosening of the fixed clamp 7.
Although specific embodiments have been illustrated and described, numerous modifications and variations are still possible without departing from the essence of the invention. The scope of the invention is limited by the accompanying claims.
