Abstract

The utility model relates to a scanning laser face care instrument, particularly a scanning carbon dioxide laser face care instrument which can generate various geometrical figures can control the depth and the area of the evaporated skin. The utility model is mainly composed of a laser generator, a light guide arm, a scanner and an operating handle. The utility model is characterized in that two reflecting glasses lenses of the scanner are parallel with two rotary shafts with a motor; vertical shaft faces of each motor are fixed with spring fixed racks; a plurality of springs are respectively fixed between the spring fixed racks and glasses lens installation racks. The utility model can generate various scanning patterns which are used for evaporating the cuticle of the skin, removing the scar, etc.

Description

A kind of scanning type laser beautifying device

This utility model relates to a kind of beautifying device, refers to a kind of scan-type carbon dioxide laser beautifying device that can produce various geometric figures and can control vaporization skin depth and area especially.

Present scan-type carbon dioxide laser beautifying device mainly is made up of laser generator [1], light-conducting arm [2], scanning device [3] and operating grip [4], as shown in Figure 1.Its scanning device is made of two motors [5], [6], reflecting optics [7], [8], focusing lens [9] and control power supply [11], as shown in Figure 2.The vertical installation of turning cylinder of this reflecting optics and motor, two motors provide constant DC by control power supply [11] and press during use, make it respectively with angular velocity omega ₁And ω ₂Rotation after laser beam [12] passes through two reflecting mirrors and lens, is gone up Li Shayu (Lissajous) figure that generation circle shape shrinks at target surface [10].The weak point of this beautifying device is to produce single scanning patter, and promptly Yuan Xing scanning patter has very big limitation in practical application, and its scanning speed and the difficult accurately control of size.

The purpose of this utility model is to provide a kind of not only can produce the circular scan figure, and can produce the laser cosmetic instrument of multiple scanning patters such as square, rectangle, triangle, and each scanning patter can have different scan sizes and sweep time.

Content of the present utility model is: a kind of scan-type carbon dioxide laser beautifying device, form by laser generator, light-conducting arm, scanning device and operating grip, it is characterized in that: two reflecting optics in the scanning device by two eyeglass installing racks respectively with the parallel installation of the turning cylinder of two motors, fix a spring installing rack on the vertical axial plane of each motor, several springs are separately fixed between spring anchorage bracket and the eyeglass installing rack, and the control power supply links to each other with two motors.

Advantage of the present utility model and effect: two motors that the control power supply of this scanning type laser beautifying device is given scanning device are during with the alternating voltage of different frequency and amplitude or pulsed drive voltage, the moment that magnetic force moment that motor produces and spring produce interacts, drive the reciprocating motion of reflecting optics generation around motor rotation axis, according to the synthetic principle of motion, when laser beam passes through the eyeglass of such two mutual double vibrationses, can on target surface, produce circular, square, rectangle, multiple figure such as triangle, and with the frequency of the driving voltage of two motors of one-chip computer control, phase place, pulse width, voltage amplitude can accurately be controlled the figure that produced and the physical dimension and the graph scanning time of figure.The degree of depth and the area size of may command vaporization skin when this beautifying device of practical application.

Below in conjunction with accompanying drawing for an embodiment:

Fig. 1 is an overall construction drawing of the present utility model.

Fig. 2 is the structural representation of the scanning device of existing laser cosmetic instrument.

Fig. 3 is the structural representation of the scanning device in this utility model.

Fig. 4 is the motor axial of the scanning device in this utility model.

Embodiment:

A kind of scan-type carbon dioxide laser beautifying device mainly is made up of laser generator [1], light-conducting arm [2], scanning device [3] and operating grip [4], as shown in Figure 1.Scanning device is made of two motors [13], [14], reflecting optics [15], [16], focusing lens [17] and control power supply [24], two reflecting optics [15], [16] by eyeglass installing rack [18], [19] respectively with the parallel installation of turning cylinder of two motors [13], [14], fix a spring anchorage bracket [20], [21] on the vertical axial plane of each motor, spring [22], [23] are separately fixed between spring anchorage bracket [20], [21] and eyeglass installing rack [18], [19], control power supply [24] is connected with two motors [13], [14], as shown in Figure 3, Figure 4.

During use, operator as required, parameters such as the voltage magnitude of selected drive motors and frequency, pulsewidth can be determined the scanning patter of scanning device, dimension of picture, sweep time.

As when the needs circular scan pattern, then the driving voltage amplitude of selected two motors is 1V, and frequency is 100HZ, and the phase contrast of two voltages is when being pi/2, and can obtain diameter is 2mm, and the scan period is the circle of 10ms.

During as the square scan pattern of needs 3 * 3mm then the driving voltage amplitude of a selected motor be 3V, frequency is 100HZ, the driving voltage cycle of another motor is 10ms, when increment value was the stepped-up voltage of 0.5V, scan synthesis was the square of 3 * 3mm.

In like manner can obtain multiple different scanning patter as required.

This instrument can be used to the keratodermatitis of vaporizing, and wrinkle is shunk, and removes cicatrix.
