Abstract

PROBLEM TO BE SOLVED: To prevent scald caused by hair removal with laser (1), to reduce time for hair-removing treatment (2) and to eliminate irregularity of hair removal in hair-removing treatment (3). SOLUTION: (1) This hair-removing equipment eliminates irregularity of hair removal by removing the hair by plane by scanning the hair in a transverse direction with a line laser beam. (2) By irradiating a hair-removing treatment part with intense pulse beams of solid state laser without using the waveguide of an optical fiber, etc., the hair-removing treatment can be accelerated. In the hair-removing equipment, a compact laser oscillator is mounted on a laser irradiation tip part for realizing intense laser pulse light. (3) The equipment irradiates the hair with laser beams by synchronizing a moving speed and a laser beam irradiation time with each other so as to irradiate the hair removing treatment part with the laser beam after changing an irradiating position so as to avoid fixing of the laser beam to a single place.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aesthetics, medical, and hair removal device for animals.

[0002]

2. Description of the Related Art In the current field of beauty treatment, an operator holds a laser irradiation end and irradiates the skin to be hair-removed with laser light. At this time, inadvertently prolonging the irradiation time often caused deep burns to the skin. In addition, since the shape of the laser beam irradiated onto the skin is circular, it is necessary to superimpose the laser beams at a high rate in order to eliminate the laser irradiation leakage. Therefore, it takes a long time to remove hair on a wide hair removal area such as human legs, arms, and armpits.

[0003]

When the hair is removed, the operator's carelessness causes burns at the hair removal site due to excessive irradiation of laser light.

Since the shape of the laser beam to the hair removal site is circular, in order to irradiate all hair removal sites with laser light, it is necessary to superimpose the laser beams at a high rate, and it takes a long time for hair removal. ing.

Since a large-sized laser device has been necessary for the laser hair removal device, an optical fiber, an optical waveguide and the like have been indispensable. Therefore, in order to prevent damage to the optical fiber and the waveguide, the high energy giant pulse cannot be used. Further, a large energy loss occurs because the laser light is transmitted through the optical fiber and the waveguide.

[0006]

In order to solve the above problems, the present invention is characterized by having the following configuration.

The laser epilation apparatus of the present invention mounts a compact laser transmitter and an optical system for forming a linear laser beam on a movable table which is movable on the skin. 1) In the device, the moving table is moved by the motor power via the wheels. The interlock is released when the wheel is placed on the skin. By stepping on the foot switch, electric power is supplied from the control box to the motors that move the wheels, and the mobile platform starts moving. The sensor detects the rotation angle of the wheel, and sends a signal synchronized with the rotation angle to the Q switch in the laser oscillator to oscillate a laser pulse. 2) This laser pulsed light is shaped into a linear laser beam of uniform energy via waveform shaping optics. Irradiate this line laser beam to the skin area where you want to remove hair
It is a device for removing hair by moving the linear laser beam. 3) This device automatically moves and synchronizes with the laser pulse to irradiate the designated laser energy to the same place, thereby preventing burns caused by the laser. 4) Also, by moving the linear laser beam,
Allows uniform hair removal on a wide skin surface. By using high-repetition, high-energy laser pulsed light by the Q switch, hair removal with less hair loss can be achieved in a short time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic view of this device. 1 is a compact Q-switched laser device and 2 is a laser beam shaping optics mounted on a movable table. By placing the moving table 3 on the skin to be hair-removed, the interlock attached to the wheel shaft 6 of the wheel 4 is released. In this state,
The laser irradiation is ready.

Reference numeral 5 denotes a foot switch, and when the foot switch 5 is stepped on, the motor of the wheel 4 starts to move. Then, the moving table 3 starts moving on the skin. When the wheel 4 starts to rotate, the encoder attached to the wheel shaft 6 causes the wheel 4 to rotate.
The rotation angle detection pulse signal of can be detected by the ROM 8 in the control box 7. Upon receiving the rotation angle sensing pulse signal, a Q switch signal for generating the number of laser pulses designated by the ROM 8 is sent to the laser device 1.

The laser device 1 receiving the Q switch signal oscillates a pulse laser. This laser light is reflected by the mirror 9, guided vertically downward, and enters the laser beam shaping optics 2. The laser beam shaping optics 2 shapes the laser beam into a linear laser beam having a uniform energy distribution.

It is possible to achieve uniform hair removal on the surface of the skin to be removed by moving the laser in a lateral direction of the line while irradiating the line laser beam having a uniform energy distribution with pulses.

FIG. 2 shows an operation signal histogram of the developed device. When the power switch is turned on, power is supplied to the cooling unit of the laser device and cooling is started. The hair removing device can be operated when the set cooling temperature is reached.

When the moving table 3 is placed on the hair-removing skin, the interlock attached to the wheel shaft 6 is released. When the foot switch is stepped on in that state, a signal is input from the controller to the motors for moving the wheels, and the moving platform moves at the specified speed. At this time, the encoder attached to the rotary shaft 6 sends a rotation angle detection signal of the rotary shaft 6 to the control box, and the ROM 8 sends a Q switch-on signal to generate a laser pulse corresponding to the rotation angle. generate.
