DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0009]
FIG. 1 shows an overall view of a complex skin beautifying apparatus embodying the present invention.
The complex skin beautifying apparatus connects the probe 30 to the side surface of the main body 10 via the cable 20.
The main body 10 has a built-in control circuit 40, a probe storage section 50 and an operation panel 60 are provided on the upper surface, and a lid 70 is attached on the upper side.
[0010]
The operation panel 60 includes a power switch S1, a standby state changeover switch S2, and an irradiation time setting switch S3, respectively, on the panel surface.
In addition, an LED power lamp L1, a standby state lamp L2, and an irradiation time lamp L3 for displaying six levels of irradiation time are installed corresponding to each switch.
Irradiation time lamp L3 uses a red and green LED chip in one lamp, and one or both of them are lit to emit red, green, yellow or orange (amber) light. To do.
[0011]
The power switch S1 turns on / off the power supply of the main body 10.
At this time, the power lamp L1 is turned on when turned on and turned off when turned off.
[0012]
The standby state changeover switch S2 switches the standby state of the probe 30. When the standby state changeover switch S2 is turned on, the standby state is changed to the standby state, and when the probe 30 is turned off, the standby state is released.
At this time, the standby state lamp L2 is turned on when turned on and turned off when turned off.
The initial standby state when the power switch S1 is turned on is set to off.
When the standby state changeover switch S2 is turned on, the timer count starts. When a predetermined time (for example, 20 minutes) elapses, the standby state changeover switch S2 is automatically turned off.
[0013]
The irradiation time setting switch S3 switches the irradiation time for one irradiation of laser light to 1 to 6 steps every time the switch is pressed.
At this time, the display of the irradiation time lamp L3 is switched in the order of green lighting, green flashing, orange lighting, orange flashing, red lighting, and red flashing corresponding to the irradiation time of 1 to 6 steps. The irradiation time setting switch S3 can be operated to set the irradiation time even when the standby state changeover switch S2 is on.
The initial irradiation time when the power switch S1 is turned on is set as the first irradiation time.
In addition, the time interval of intermittent irradiation is set to a preset number of seconds (for example, 1.5 seconds).
[0014]
2, 3, and 4 are a front view, a rear view, and a side view with a part cut away of a probe embodying the present invention.
The probe 30 has a head portion H projecting from the front, and push switches S4 and S5 are attached to the left and right side surfaces.
Further, ventilation holes a and b are provided on the lower side and the back side of the head portion H, respectively.
[0015]
The head portion H has an opening at the center thereof, and a ball lens 31 is inserted thereinto. A tip tube 32 whose tip is to be brought into contact with the skin is integrally attached to the outer periphery of the ball lens 31.
A cylindrical electrode 33 is embedded in the tip of the front tube 32 so that the tip protrudes forward from the opening end surface.
A heat sink 34 is attached to the rear of the ball lens 31, and a semiconductor laser diode 35 is inserted into the inner part of the shaft center with a through hole.
A fan 36 for cooling the heat sink 34 is installed behind the fan 36.
[0016]
The spherical lens 31 condenses the laser light of the semiconductor laser diode 35 and focuses it on the opening end surface of the front tube 32. However, since the focal length is shorter than that of a normal lens, the optical power is reduced to a narrow range with a small focal depth. You can narrow down.
On the contrary, it spreads at the same angle from the position past the focal point, and the optical power is dispersed over a wide range.
For this reason, since the energy density becomes low and the optical power decreases at a position past the focal point, the risk of damaging the living body is reduced even if it is accidentally irradiated.
[0017]
The heat sink 34 diffuses heat generated during operation of the semiconductor laser diode 35 by heat conduction to suppress a decrease in output.
Therefore, it casts with aluminum or its alloy with good heat conduction efficiency, and provides some dummy through-holes to improve heat dissipation efficiency.
[0018]
The semiconductor laser diode 35 is excited by applying a current directly to a PN junction diode using a compound semiconductor such as GaAs to obtain laser oscillation. In addition, laser light having a peak wavelength of 600 to 1600 nm and an optical output of 5 mW to 3 W is output, and the thermal efficiency is good and sufficient photothermal reaction is caused on the skin.
In addition to thermal reactions, there are photoelectric reactions, photomagnetic reactions, photodynamic reactions, photochemical reactions, photoimmune reactions, photoenzymatic reactions, etc., and photobiological activation promotes metabolism of living tissues to promote skin circulation. It has high skin penetration because it is not easily absorbed by water or blood.
[0019]
On the back side of the head portion H, a conical vibrating body 37 having a trapezoidal cross section having a flat front end surface is formed by opening the back surface of the probe 30, and an ultrasonic transducer 38 made of piezoelectric ceramics is fixed to the inside.
[0020]
The back side of the head portion H is formed of an electrically insulating material made of a flexible elastic material such as synthetic resin, and the vibration body 37 attached to the opening is mechanically insulated so as not to restrain the vibration of the vibration body 37.
[0021]
The vibrating body 37 is formed of a metal such as a thin and flexible stainless steel plate, light and hard aluminum, titanium, duralumin, or a thin copper plate, and is subjected to a surface treatment such as hard chrome plating.
[0022]
FIG. 5 shows a block diagram of a control circuit of the complex skin beautifying apparatus embodying the present invention.
The control circuit 40 incorporates a memory 42 and a timer circuit 43 in the CPU 41, a standby state changeover switch S2, an irradiation time setting switch S3, push switches S4 and S5 of the probe 30 on the input side of the I / O port 44, A touch sensor circuit 45 that detects contact of the electrode 33 with the human body is connected, and a drive circuit 46 that controls the operating current of the semiconductor laser diode 35 and an excitation power source 47 of the ultrasonic transducer 38 are connected on the output side.
[0023]
The touch sensor circuit 45 includes a high-frequency oscillation circuit and a switching circuit that turns the output on and off depending on the presence or absence of oscillation.
Then, the electrode 33 is connected to one end of the oscillation coil of the high-frequency oscillation circuit, and the output of the switching circuit is switched from on to off using the fact that the oscillation stops when the electrode 33 touches the human body.
In addition to this, the touch sensor circuit 45 may be one that detects contact by a change in impedance such as capacitance or resistance, or one that detects contact by a switch or a piezoelectric element.
[0024]
The excitation power supply 47 amplifies the oscillation output of the oscillator with an amplifier and applies a high frequency current to the ultrasonic transducer 38.
The oscillation frequency and oscillation output of the oscillator are controlled by feeding back the current flowing through the ultrasonic transducer 38 to the input side.
[0025]
The CPU 41 also performs timer control to turn on / off the operating current of the drive circuit 46 by the interruption of the timer circuit 43.
The timer control includes a treatment time control in which a treatment time is set to turn on / off the operating current, and an irradiation time control in which the operation current is turned on / off by setting a single irradiation time of intermittent irradiation. .
One irradiation time of intermittent irradiation is set by an irradiation time setting switch S3.
[0026]
The composite skin beautifying apparatus of the present invention is configured as described above. When performing a treatment, first, the power switch S1 of the main body 10 is turned on.
Next, the irradiation time setting switch S3 is pressed to switch the irradiation time, the pressing of the switch is stopped at the desired irradiation time, and one irradiation time of intermittent irradiation is set.
Next, the standby state selector switch S2 is turned on to place the probe 30 in the standby state.
[0027]
When performing skin beautification treatment with laser light, the probe 30 is held in the hand, the front head portion H is directed at a right angle to the skin surface, and the tip of the tip tube 32 is pressed to bring the electrode 33 into close contact with the skin.
When the push switch S4 is pressed in this state, the semiconductor laser diode 35 is lit for the set number of seconds and then rests for a specified number of seconds.
The skin is intermittently irradiated with laser light while repeating this irradiation and pause.
In this way, the electrode 33 is brought into contact with the skin, the laser beam is irradiated, and the treatment is performed while sequentially moving the position.
[0028]
When performing skin beautification treatment by ultrasonic vibration, a medium such as cream or gel is applied to the treatment site or the surface of the vibrating body 37 of the probe 30 to enhance the propagation efficiency of ultrasonic waves.
Next, the front and rear of the probe 30 are reversed and held in the hand, the vibrating body 37 on the back is directed toward the skin surface, and the push switch S5 is pressed.
As a result, a high-frequency current from the excitation power supply 47 is applied to the ultrasonic vibrator 38, and the vibrating body 37 undergoes bending deformation to ultrasonically vibrate.
When the ultrasonic vibration starts, the probe 30 is moved along the skin surface so as to slowly draw a circle while pressing the vibrating body 37 lightly at right angles to the skin surface.
The probe 30 may be attached so that the head portion H can freely turn and when the treatment of laser light and ultrasonic vibration is switched, the head portion H may be reversed back and forth.

[0030]
In addition, the composite skin beautifying device of the present invention is provided with a hand switch for operating on / off of the excitation power source and the excitation power source separately on the probe. Therefore, according to the present invention, the power source can be turned on / off by the hand holding the probe.
