Description

Description: TECHNICAL FIELD The present invention relates to a low-frequency beauty device that applies low-frequency waves to the human body to perform facial treatment, beautiful skin treatment, or treatment.

(Prior Art) Conventionally, a low-frequency facial beauty device that performs a skin-cleansing action on a human body, particularly a face, outputs a low-current low-frequency signal such as a rectangular wave and gives this signal to the human body. This low-frequency signal flows through the closed circuit formed between the circuit output in the body of the low-frequency facial device and the human body to perform facial effects, etc., and whether such a low-frequency signal is actually output. In order to detect this, an attachment for giving a low frequency signal from the main body circuit to the human body is brought into contact with the human body, and there is a pain due to the current, or an indicator is provided to display the current that has flowed into the human body. Check that the meter is displaying the current value.

However, even if such an facial device is operated and the attachment is brought into contact with the human body, the person does not feel the pain,
If the indicator displays the current value OmA, that is, if the closed circuit through the human body is not formed, the cause is the setting error such as the push button switch operation on the user side, or the connection error of the attachments. There is a tendency that it is difficult for the user to easily determine whether it is a failure of the main circuit or a disconnection of the attachment cords.

(Object of the Invention) The present invention solves the above-mentioned technical problem, and by displaying the display means indicating that the circuit for outputting a low-frequency signal is normally operating and is in the energization output ready state, the attachment is brought into contact with the human body. A closed circuit is formed so that the display means showing that the human body is energized is also used as the preset current value display means provided on the main body side so that the user can easily check the usage state. The object is to provide a low frequency beauty device.

(Structure of the Invention) The present invention provides a low-frequency output means for outputting a low-frequency signal given to a human body, a setting means for variably setting a current or a frequency of the low-frequency signal, and a low-frequency signal set by the setting means. Display means for displaying the current value or frequency, output detection means for detecting that the low-frequency signal is output from the low-frequency output means, and contact detection means for detecting that the attachment contacts the human body. In addition, at least a part of the display means is made to blink in different cycles according to a signal from the output detection means or a signal from the contact detection means.

With this configuration, the blinking cycle of the display means differs between the state where the low-frequency signal is normally output from the low-frequency output means and the state where the attachment is in contact with the human body and is energized. You can

Next, the operation of this embodiment will be described with reference to the flow chart shown in FIG. In step S ₁ , the power plug 9 of the main body 1 is inserted into an AC power outlet (not shown),
The power switch 2 is turned on, the power supply in step S ₂ is illuminated lamp (not shown) indicating that it is turned is turned on. In step _{S 3,} CPU 17 enters the operating state, this time, the current value indicator 5 is initial setting, the number "0.
"0" is displayed. That is, the current value indicator lamp 5 indicates that the low frequency signal from the low frequency constant current output circuit 16 is 0.0 mA. Further, in the step _{S 3,} up pushbutton switch 3 and a down push-button switch 4 is input receivable state with respect to CPU 17.

In step S _4, by pressing the up pushbutton switch 3 or Down push button switch 4 sets the current value of the low-frequency signal to be energized to the human body A. The set current value is displayed on the current value indicator lamp 5. For example, if the current value is 3.0 mA, the current value indicator lamp 5 displays "3.0".

In step S _5, CPU 17 is thereby set the current value data corresponding to the current value displayed on the current value indicator 5 on the low-frequency constant current output circuit 16, and state accepting input a start / stop push button switch 6 . In step _{S 6,} CPU 17 is a start / stop push button switch 6 is determined whether or not turned on, when it is turned on proceeds to step _{S 7,} CPU 17 is a current output relay coil 1
