Further, a lid 14 is attached to the main body box 10, and the upper surface is covered with the lid 14. A mirror 140 is attached to the lid 14 and a through hole 141 is formed.

  The operation unit 11 includes a power button 110 for turning on / off the battery power, mode buttons 111 and 112 for setting the laser light output mode, and a radio wave output button 113 for turning on / off the output from the radio wave output circuit. It is arranged on the upper surface of the box 10.

The display unit 12 includes an LCD 120 that displays an operating state of the skin beautifying device 1 and an LED lamp 121 that indicates a charging state of a battery power source.
For example, as shown in FIG. 2, the LCD 120 includes a time display unit 122 that displays a startup time after the power is turned on, a mode display unit 123 that displays a laser light output mode, and a level meter that displays an output level. 124 and a radio wave display unit 125 for displaying on / off of the radio wave output circuit. The LCD 120 starts to operate when the battery power is turned on.
In addition, the LED lamp 121 is disposed at a position where the through hole 141 comes when the upper surface of the main body box 10 is covered with the lid 14 so that the blinking state of the LED lamp 121 can be seen with the lid 14 on. This LED lamp 121 lights up or blinks when the skin beautifying device 1 is being charged.

  The probe storage unit 13 is formed by forming a recess 130 having a size that allows the probe 30 to be accommodated on the upper surface of the main body box 10 and a narrow belly holding part 131 that holds the connection part 21 between the probe 30 and the cord 20. The probe 30 is fixed to the recess 130 by the portion 130, and the probe 30 is held in the storage portion 13 by covering the upper surface with the lid 14. A storage groove 15 is formed along the side surface of the main body box 10.

Next, the probe will be described. FIG. 3 is a perspective view showing a probe of the skin beautifying apparatus according to the present invention.
The housing 31 of the probe 30 is formed in a flat and slender pen shape having an elliptical cross section, and gradually increases in diameter from the rear end to the front end to which the cord 20 is connected, and becomes the maximum diameter slightly at the front end side from the center. The diameter is configured to be small. The tip of the housing 31 is formed by a head cover 310 made of a light transmissive material. An elongated slit-shaped opening 312 is formed in the front end surface 311 of the head cover 310 in the major axis direction of an elliptical cross section. Further, the antenna electrode 33 and a pair of touch sensor electrodes 34 and 34 are attached to the distal end surface 311, and the output button 32 is provided on the surface side where the diameter of the housing 31 is maximum and on the surface side having a large curvature radius.

FIG. 4 is a cross-sectional view of the probe.
An antenna electrode 33 and a touch sensor electrode 34 are attached to the front end surface 311 of the housing 31 so as to protrude from the front end surface 311. The antenna electrode 33 is connected to a radio wave output circuit built in the main body box 10 via the cord 20. A current is supplied from the radio wave output circuit to radiate a radio wave from the antenna electrode 33.

  Radio waves vary in energy and permeability to the human body depending on the frequency. If the frequency of radio waves is higher than 100 MHz, energy may increase and local heat generation may be too large. On the other hand, the frequency is higher than 1 MHz. If it is low, a sufficient calorific value cannot be obtained and an effective skin treatment cannot be performed. Therefore, the frequency of the radio wave radiated from the antenna electrode 33 is preferably 1 MHz to 100 MHz, and preferably 3 MHz to 30 MHz. At this time, the radio wave is absorbed in a region having a depth of about 1 mm to 3 mm from the surface of the skin and causes a thermal action, so that the skin beautifying treatment can be effectively performed.

A laser light source 35 and a light transmitting body 36 having a rectangular cross section are attached inside the housing 31, and one end of the light transmitting body 36 is coupled to the light emitting surface of the semiconductor laser element 35. The tip of the light transmitting body 36 on the opening 312 side is installed so that its long side is parallel to the length direction of the slit-shaped opening 312, and the skin can be irradiated with linear laser light from this opening 312. Constitute. The light transmitting body 36 is surrounded by a reinforcing body 37 so that the light transmitting body 36 is not damaged, and the emission end is exposed from the reinforcing body 37. A through hole 370 is formed in the reinforcing body 37, and an adhesive is injected into the through hole 370 to fix the light transmitting body 36.
Further, an LED lamp 38 is attached in the vicinity of the head cover 310, and when the laser beam is irradiated or radio waves are emitted, the LED lamp 38 is turned on through the light-transmissive head cover 310, and the laser beam is output. Inform them and call attention.

Next, the usage method and operation | movement of the skin beautifying device 1 are demonstrated.
First, when the power button 110 is pressed to turn on the power, the LCD 120 is turned on, and the startup time, the laser light output mode, and the like are displayed. At this time, the output mode of the laser beam is a mode 0 in which no laser beam is output, the radio wave output circuit is also turned off, and the laser beam is not irradiated even when the output button 32 of the probe 30 is pressed. No radio waves are emitted from the electrodes.

Next, the laser beam output mode is determined by the mode buttons 111 and 112. In the present embodiment, the laser light output mode can be adjusted in three stages of mode 1 to mode 3.
When the output mode is determined, when the output button 32 is pressed by touching the touch sensor electrodes 34 and 34 of the distal end surface 311 of the probe 30 to the skin, laser light is emitted. While the laser beam is being output, the LED lamp 38 is turned on. The light beam of the laser beam spreads linearly by the light transmitting body 36, and a laser beam having an appropriate intensity can be applied over a wide range.

  Further, while the output button 32 is being pressed, the laser beam is intermittently irradiated, and the laser beam is output continuously for 3 seconds, and then the output is stopped for 2 seconds. At this time, the output level of the laser beam is modulated by the control circuit in a pattern determined in each output mode. In the present embodiment, the output level of the laser beam is variable in eight steps from L1 to L8, and the laser beam with higher intensity is irradiated when the number is larger.

  Specifically, in the mode 1, the modulation pattern of the output level is L1, L2, L3, L2, L1, L2, L3, L4, L3, L2, L1, L2, L3, L2, L1, etc. In the range of relatively weak laser intensity, the temperature is changed uniformly at intervals of 0.2 seconds, and three peaks are taken to uniformly generate a thermal effect in the range from the shallow region to the middle region of the skin. Can do.

In mode 2, it changes like L2, L3, L4, L5, L6, L5, L4, L3, L4, L5, L6, L5, L4, L3, L2, and in mode 3, it changes to L3, L4. , L5, L6, L7, L8, L7, L6, L7, L8, L7, L6, L5, L4, L3, and changes twice periodically with a relatively strong laser intensity range Take.
As a result, it is possible to cause a thermal effect in a deep region from the skin surface at a site where intensive treatment is desired due to spots and freckles, and to prevent the local calorific value from becoming too large.

When the laser beam is irradiated, the level meter 124 of the LCD 120 changes according to the output level of the laser beam. FIG. 2 shows a state in which the output level of the laser beam is L2, and the level meter 124 is displayed in black from the bottom to the second stage.
When the laser beam is radiated, the level meter 124 moves rhythmically up and down in accordance with the modulation of the output level of the laser beam, so that the change in the laser intensity can be visually recognized and treatment is performed. You can enjoy the change of display visually and never get bored.

On the other hand, when the power button 110 is turned on to determine the output mode, the timer is started, and when a certain time (for example, 10 minutes) elapses, the timer is automatically turned off. At this time, the time display section 122 of the LCD 120 displays the remaining time until the power is turned off by the timer. FIG. 2 shows that the remaining time is 10 minutes. Thereby, it can prevent that it heats too much by the treatment over a long time, and can improve safety | security.
Further, a power saving configuration is adopted in which the power is automatically turned off even when there is no input from the operation unit 11 for 2 minutes after the power is turned on.

  When the radio wave output button 112 of the operation unit 11 is pressed to turn on the radio wave output circuit, RF characters indicating that radio waves are output are displayed on the radio wave display unit 125 of the LCD 120, and the probe 30 is touched in a state where these characters are displayed. When the sensor electrode 34 is placed on the skin and the output button 32 is pressed, a current is supplied from the radio wave output circuit, and radio waves are emitted from the antenna electrode 33, so that skin beautification treatment can be performed by the dielectric heating effect. When radio waves are radiated from the antenna electrode 33, the LED lamp 38 is turned on.

  The skin beautifying device 1 configured as described above can warm different regions by the thermal effect by laser light and the dielectric heating effect by radio waves, so that the blood circulation of the skin is efficiently promoted and the metabolism is activated, A beautiful skin treatment.

  By modulating the output level of the laser beam, the heat distribution of the skin due to the thermal action can be greatly expanded in the depth direction, preventing local overheating, and the output level is modulated by changing the output mode By changing the period and the average intensity of the laser beam to be modulated, it is possible to select a depth that gives a thermal action and to obtain a desired treatment effect efficiently.

  In addition, the radio wave can warm a predetermined depth region in a wide range by its dielectric heating action, and more effective and effective treatment can be performed by using it together with the thermal action by laser light.

  Furthermore, laser treatment is intermittently performed, and the timer is turned off after a lapse of a certain time, so that excessive treatment is prevented and the skin is not overheated.

In addition, since the probe is formed in a flat and slender pen shape, it is easy to hold and excellent in handleability, and since it is elongated, it is easy to treat parts such as the circumference of the nose, A skin treatment can be performed evenly by radio waves radiated over a wide area.
Further, since the output button 32 is formed on the surface having a large radius of curvature of the housing, when the output button 32 is pushed with the thumb, the linear laser beam is changed in the length direction by rotating the wrist around the arm. The skin can be moved in a right-angle direction, and skin treatment can be performed efficiently and without unevenness.
