Abstract
The present invention provided a laser depilating device for performing quick are sure depilating processing expected by a person who wants depilation. This optical system of a depilating laser irradiation port is combined with a semiconductor laser generating element to realize the quick and sure depilating processing expected by the depilation wisher.
Description
The present invention relates to a kind of apparatus for laser depilation that effectively loses hair or feathers and handle.
In the past, in normally used apparatus for laser depilation, the high heat that utilizes laser to have made the Rhizoma Imperatae damage of skin inside and hair was removed.
But, when laser that general employed apparatus for laser depilation sends a little less than, and when once the laser area that shone in the left and right sides is narrow and small at large, situation about handling according to the hope depilation, handling in order all to lose hair or feathers needs spended time to finish.But, grow later virgin wool under many circumstances again having finished the place that depilation is handled.In order not destroy Rhizoma Imperatae, the laser that this mode is sent a little less than.
Therefore, the apparatus for laser depilation that on market, provides the performance that can solve following shortcoming to increase substantially.In this device, in order to improve the operability at the laser irradiation position that connects with cable near depilation laser master device (below, be called the laser irradiation position), control as one hand, can move freely, need make its volume little and in light weight.Further, in order to make the laser loss that sends terminate in Min., for example the optical fiber that sends laser near depilation laser master device does not import to the laser irradiation position, can be luminous at the laser irradiation position, irradiation, opticator laser transmittance at this irradiation mouth improves as shown in the figure, thereby effectively.
The invention provides addressing the above problem useful device.In order to realize fast, positively to lose hair or feathers, at first to select laser.
Though several theories that caused depilation about why by laser are arranged, generally have following situation.The melanin that exists around Rhizoma Imperatae can react with laser.There is Rhizoma Imperatae the epidermis inside of human body, and near the melanin that surrounds its periphery forms thick-layer.In order to destroy Rhizoma Imperatae, the melanin thick-layer that exists around Rhizoma Imperatae will inevitably fully absorb the heat energy of laser.And, if the absorbance of this heat energy is too high, burnt in the place of irradiation.
Therefore, can make the laser that sends have the wavelength (for example 750 nanometers-900 nanometer) of suitable near infrared region, adopt the semiconductor laser of favourable miniaturization and.And, in order to reduce laser loss, in the optical system of laser irradiation mouth, adopt the non-spherical lens and the cylinder mirror of new ideas.
The basic comprising of the optical system of depilation laser irradiation mouth of the present invention is that semiconductor laser, inner face are reflecting mirror cylindraceous and aspheric lens.And, can singlehanded control the lose hair or feathers structure of the miniaturization and handled and the main device part of profile and apparatus for laser depilation thereof of laser irradiating part and be connected by the optical fiber winding.
Adopt near the protruding simple lens the focal length f=25 millimeter, the optical system of the apparatus for laser depilation miniaturization that becomes, thereby price becomes cheap.Semiconductor laser 2 of the present invention is to be made of hundreds of laser cells, and the lighting angle of these single laser cells is about 40 ° an of vertical direction, about 20 ° of horizontal direction, and it is luminous to carry out ellipse.Consider that there is following process in optical system, for example its diameter of standard convex lens of f=25 millimeter is below 25 millimeters, because its diameter is little, vertical direction is that 40 ° light can produce loss when inciding lens.Therefore can adopt the f=25 mm dia is 40 millimeters lens, non-spherical lens 4.Zhou Bian light exhales from lens like this, and it is big that the loss of laser becomes.At this moment, under need not the state of following reflecting mirror 3, the transmitance of laser be below 70%.
Therefore, outwards not disperse in order making at the laser of aspherical mirror 4 peripheries, to consider to adopt columnar reflecting mirror, the laser of periphery is assembled at aspherical mirror 4, has realized the transmitance more than 90%.
Fig. 1 is the sketch map of the optical system of depilation laser irradiation mouth of the present invention;
Fig. 2 is in the optical system of depilation laser irradiation mouth of the present invention, and the surface becomes the sketch map of the embodiment of oval non-spherical lens;
Fig. 3 is the sectional drawing of III among Fig. 2-III direction;
Fig. 4 is the sectional drawing of IV among Fig. 2-IV direction;
Fig. 5 is that the surface becomes the sketch map of the embodiment of parabolical non-spherical lens in the optical system of depilation laser irradiation mouth of the present invention;
Fig. 6 is the sectional drawing of VI among Fig. 5-VI direction;
Fig. 7 is the sectional drawing of VII among Fig. 5-VII direction.
Fig. 1 is the sketch map of the laser irradiation mouth of apparatus for laser depilation, and the reflecting mirror 3 of drum and non-spherical lens 4 make up at semiconductor laser 2 places.The number of the employed optical system of this invention (parts) tails off as shown in Figure 1, and the loss of sending laser so also diminishes, thereby reaches the purpose of the miniaturization and of this laser part and irradiation mouth.
In embodiment as shown in Figure 1, the skin area that laser can shine is 10 millimeters angles, and irradiation energy is 10-50 joule/square centimeter, and this performance is compared with existing known technology, and price and performance are more superior.
Fig. 2 is the sketch map of the laser irradiation mouth of apparatus for laser depilation, wherein has the surface to become oval non-spherical lens, and Fig. 5 becomes the sketch map of parabolical non-spherical lens for the surface.
From above-mentioned detailed description as can be known, semiconductor laser generation array emitted laser loss of the present invention is less, wishes that by irradiation the place of depilation can obtain effect preferably.Like this, just provide a kind of apparatus for laser depilation, given and wish that the epilator carries out quick, certain depilation that they expected and handles.
