Abstract

PROBLEM TO BE SOLVED: To solve the problem that if ultrasonic vibration is continued with a probe off the skin, the probe is heated by the ultrasonic vibration and the problem that continued usage of the probe makes the skin dull to the stimulation. SOLUTION: The ultrasonic face massager is provided with an ultrasonic vibration element, a probe 1 to be used in contact with the skin, a main power source switch 12 and a push button switch 20 on a grip section 19 of the probe. When the push button switch is pressed with the power source switch on, oscillation is output from an ultrasonic oscillating circuit to the ultrasonic vibration element. A combination of a plurality of power distribution time signals with different ultrasound output time is made to be one cycle and several cycles per second are output, keeping a constant ultrasound output.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic cosmetic device.

[0002]

2. Description of the Related Art A conventional ultrasonic cosmetic device uses a probe for irradiating an ultrasonic wave to irradiate an ultrasonic wave to irradiate an ultrasonic wave, thereby improving a moisture content and elasticity of the skin by a heating effect and a vibration effect. Equipment.

[0003]

However, if ultrasonic vibration is continued while the probe is not in contact with the skin,
The probe generates heat due to the ultrasonic vibration, and it is dangerous to apply the probe directly to the skin. In order to solve this problem, there is a device provided with a means for detecting whether the probe is in contact with the skin, but the control becomes complicated.
Also, when the probe is separated from the skin during the movement of the probe, a warning sound is emitted or the vibration is stopped, which is inconvenient. For another purpose, if the probe is continuously applied to the skin, the skin becomes accustomed to stimulation, so that a countermeasure is required.

[0004]

In order to achieve the above object, according to the first aspect of the present invention, there is provided a probe provided with an ultrasonic vibrator and used in contact with the skin, a main power switch,
A push button switch provided on a grip portion of the probe is provided, and when the push button switch is pressed when the main power switch is turned on, oscillation is output from the ultrasonic oscillation circuit to the ultrasonic transducer. In the invention of claim 2,
With the ultrasonic output kept constant, a combination of a plurality of energization time signals having different ultrasonic output times was defined as one cycle, and several cycles were output per second.

[0005]

An embodiment of the present invention will be described with reference to the drawings. FIGS. 1A and 1B are a front view and a side view of an ultrasonic beautifier according to the present invention, showing a probe 1 having a built-in ultrasonic oscillation circuit for generating ultrasonic waves. The metal probe head 10 that comes into contact with the skin is processed into a cylindrical shape having a bottom surface by drawing or shaving, and is fixed to the probe 1. An ultrasonic vibration element that vibrates according to an output signal from the ultrasonic oscillation circuit is attached to the back surface of the surface of the probe head 10 that contacts the skin.

[0006] A grip portion 19 is formed on the lower side of the probe 1 in the figure so as to be easily held by hand. Grip part 1
9 is provided with an operation panel 11, a power switch 12, a strength selection button 13, a lamp 14 which is turned on when the probe head 10 is ultrasonically vibrated, and an LED 1
5, 16, 17, and 18 are provided. LED15
Is turned on when the power switch 12 is pressed and the power is turned on. By pressing the strength selection button 13, the average output energy to the ultrasonic vibration element can be changed, and if the selected mode is "good", the LED 1
6 is turned on, the LED 17 is turned on in the case of "normal", and the LED 18 is turned on in the case of "good". When the selected mode is “good”, the average output energy of the ultrasonic wave is 0.4 W / CmCm when “normal” is 0.9 W / CmCm, and when “good” is 1.4 W.
/ CmCm is set.

A push button switch 20 is provided on the upper side of the grip portion 19 of the probe 1 at a position where a finger inevitably comes to use. When the probe 1 is gripped while the power is turned on, the push button switch 20 is turned on. The push button switch 20 is pressed by a finger, and the probe head 10 is configured to perform ultrasonic vibration. With this configuration, it is possible to prevent the probe head 10 from overheating due to carelessness of the user. A cord 21 is connected to the lower surface of the probe 1, and power is supplied to the probe 1 from a power supply unit (not shown).

FIG. 2 is a circuit block diagram of the present invention. Electricity is supplied to the probe 1 from a general AC power supply via a cord 21. In the constant voltage circuit 30, a voltage according to the mode selection is selected by the output level control circuit 31, and a pulse that is ON / OFF controlled by the duty control circuit 32 is input. The pulse generated by the duty control circuit 32 is sent from the constant voltage circuit 30 to the ultrasonic oscillation circuit 33 at the voltage of the selected level, and the ultrasonic vibration element 34 is driven.

In the duty control circuit 32, oscillation is turned on.
The ratio between the time and the oscillation OFF time is made variable, and control is performed so as to prevent the living body from becoming accustomed to stimulation by ultrasonic waves. Specifically, 16.384 msec is set as one energization, and the energization time of one energization is increased in eight steps from 8/32 to 24/32, and thereafter, a cycle of similarly decreasing to eight levels is repeated. By making only the energizing time variable, the energy amount can be changed while the ultrasonic output is fixed. By changing the amount of output energy in this way,
It is possible to prevent the stimulation of the living body from being used. In the present embodiment, the energizing pulse width is varied stepwise, but it is also possible to use 1 / F fluctuation or the like.

[0010]

According to the present invention, the heating of the probe head can be prevented with a simple structure, and the stimulus during use can be prevented.
