The electrode connecting device 2 is connected to the external suction cup type electrode 1 through the jack below. The electrode connecting device 2 electrically connects these wires 5 and the suction cup type electrode 1 therein. Accordingly, the pulse controlled by the pulse controller 3 is transmitted to the electrode connecting device 2 of the low frequency treatment device through the pulse wiring 5 and back to the suction cup type electrode 1.

FIG. 2 is an internal block diagram of the electrode connecting device 2 of the low frequency treatment device shown in FIG. 1, and FIG. 3 is a detailed circuit diagram of the block diagram shown in FIG. As shown in FIG. 2 and FIG. 3, the negative pressure generating unit for generating the negative pressure includes approximately a motor 30, a motor driving circuit 20, a rotation speed variable switch 10, a solenoid 80, and a relay 60. The electrical pulse output unit may be composed of a control unit 40, a pulse adjustment switch 70, and an electrode 90. In addition, the switch and the operation display unit 50 and the power supply unit (not shown) is configured.

Motor 30 is a core member for generating a negative pressure in the vacuum pump not shown, the motor drive circuit 20 is configured to control the rotational speed of the motor (30). In particular, the rotational speed variable switch 10 is composed of a variable resistor and is electrically connected to the motor driving circuit 20 is configured to obtain a desired negative pressure by the user to selectively operate it.

The solenoid 80 is a member that allows the generated negative pressure to be delivered to the cup 1 through intermittent (or periodic) interruption / transmission. The solenoid 80 is operated by the relay 60, the operation state of the solenoid 80 is directly affected by the frequency of the pulse signal applied to the relay 60.

The control unit 40 is provided with a reference clock generator and a counter therein to count the reference pulse at a predetermined frequency and output the trigger signal. Moreover, it has a structure which controls the electrical control of the pulse controller 3 whole.

The pulse adjustment switch 70 is composed of a variable resistor, and is configured to adjust the desired pulse by the user. The pulse signal adjusted by the pulse adjusting switch 70 is transmitted to the relay 60 and the electrode 90 connected in parallel.

The relay 60 receives the signal of the pulse adjustment switch 70 and periodically switches to operate the solenoid 80 accordingly.

The electrode 90 is installed in the suction cup 1 so as to apply low frequency stimulation directly to the user's skin. The low frequency stimulus output from the electrode 90 operates according to the output signal of the pulse adjustment switch 70.

This change in rotational speed is directly related to the generation of negative pressure to control the degree of vacuum inside the cup 1.

Then, when the user adjusts the pulse adjustment switch 70, the current of the pulse adjustment switch 70 is variable, this current is fed back to the control unit 40 and the pulse signal corresponding to the variable current is output again.

As such, the signal whose pulse frequency is adjusted is transmitted to the relay 60 and the electrode 90 connected in parallel.
