In the second mode, after outputting an electric signal to the first second electrode unit 122-1 and the second second electrode unit 122-2, the first second electrode unit 122-1 and the third second The operation of outputting the electrical signal to the electrode unit 122-3 is repeated a total of 7 times, and a break of about 10 seconds is provided in the middle of the repetition.

Accordingly, in the second mode, the waveform continuously output from the first electrode part 121 and the second runtime (C-) in the first second electrode part 122-1 and the second second electrode part 122-2 2; 1 minute) and the waveforms output during the second runtime (C-2; 1 minute) from the first second electrode unit 122-1 and the third second electrode unit 122-3 By crossing the shoulder and trapezius, it can give the effect of cross-stimulating.

In this example, stimulation by an electrical signal is set at 6 to 9 times per second, and the voltage of the electrical signal is set between 20 and 120V, so that an excessive current flows by direct contact between the electrode and the human body so that the user does not feel pain. It may be set to maintain a constant micro-current (about 0.06 mA) per unit area.

In the third mode, an electric signal is continuously output at a predetermined period to the first electrode unit 121 , and the first cycle and the first cycle are sequentially applied to the plurality of second electrode units 122-1, 122-2, 122-3. After outputting an electrical signal having an intensity, a second period shorter than the first period and a second intensity greater than the first intensity are sequentially applied to the plurality of second electrode units 122-1, 122-2, 122-3. An electrical signal can be output.

Also, the third mode is constant for all of the plurality of second electrode units 122-1, 122-2, and 122-3 or one of the plurality of second electrode units 122-1, 122-2, 122-3. After outputting an electric signal continuously with a periodicity, and outputting an electric signal having a first period and a first intensity to the first electrode unit 121 , a second period and a second period shorter than the first period are outputted to the first electrode unit 121 . An operation of outputting an electrical signal having a second intensity greater than one intensity may be repeated.

Hereinafter, the operation of the third mode will be described, but will be described as an operation in which the voltage of the first electrode unit 121 is set to +.

7, in the third mode, the first electrode unit 121 conducts 1600u sec with a period (B-3) of 142m sec for 15 minutes for the total operation time (C-3) (A-3). ) and output 710 , and at the same time outputting 400u sec of conduction (A-31) with a 142m sec period (B-3) in the first second electrode part 122-1 and the second second electrode part At (122-2), the continuity (A-32) of 400 u sec is output with a period (B-3) of 142 m sec, and at the same time, the third second electrode part (122-3) has a period of 142 m sec (B-3) ) to output 400u sec continuity (A-33). Here, when the second electrode part is divided into four, the remaining second electrode part (not shown) outputs conduction (A-34) of 400 u sec with a period (B-3) of 142 m sec (720 to 750).

The sum of conduction (A-31), conduction (A-32), conduction (A-33), and conduction (A-34) is set to be equal to conduction (A-3).

The third mode is a plurality of second modes while the first electrode unit 121 outputs conduction (A-3) of 1600 u sec with a period (B-3) of 142 m sec for 15 minutes for a total operation time (C-3) of the first electrode unit 121 . 400u sec of conduction (A-31 to A-34) is output for 5 minutes with a 142m sec cycle (B-3) from the electrode parts 122-1, 122-2, 122-3, and after a break of about 10 seconds, 71m 400u sec of conduction (A-4) is output for 4 minutes with a sec period (B-4) (760), and after a break of about 10 seconds, 400u sec of conduction (A-5) with a 35.5 m sec period (B-5) is output for 2 minutes (770), and after a break of about 10 seconds, 7 seconds at a 142 m sec cycle (B-3), 7 seconds at a 71 m sec cycle (B-4), 7 seconds at a 35.5 m sec cycle (B-5) is repeated 10 times.

The third mode can increase the intensity of stimulation transmitted to the shoulder and trapezius by gradually outputting an electrical signal in a short cycle, thereby giving the effect of stimulating the shoulder and trapezius from a weak intensity to a strong intensity.

In this example, stimulation by an electrical signal is set at 6 to 9 times per second, and the voltage of the electrical signal is set between 20 and 120V, so that an excessive current flows by direct contact between the electrode and the human body so that the user does not feel pain. It may be set to maintain a constant microcurrent (about 0.06mA) per unit area.
