Description

[Detailed Description of the Invention] The present invention relates to a small-sized low-frequency treatment device, and more particularly to a small-sized low-frequency treatment device that converts a low-frequency signal into mechanical vibration and performs treatment by applying this vibration to a person.

Conventionally, various types of treatment devices have been devised, including acupressure point stimulators that stimulate acupuncture points, and a variety of devices designed to stimulate the human skin and nerves by applying low-frequency pressure to the human body. . However, this type of treatment device has various problems, such as the large size of the device and the fact that the electrodes are separated from the main body.

Therefore, the present invention has been made to eliminate such conventional drawbacks, and an object thereof is to provide a small and inexpensive low frequency treatment device.

The present invention will be described in detail below based on embodiments shown in the drawings.

1 and 2 schematically illustrate the general structure of the treatment device according to the present invention from the front and back sides, respectively. A power switch 2 is arranged on the front surface of the housing 1, and a pressure vibration switch is placed on the left side of the housing 1. A level switch 3 is provided to adjust the strength of the power, and a power supply section 4 made of a solar cell is further disposed in the lower part. Further, a lighting lamp made of a neon tube is arranged on the upper right side of the power switch 2. Further, on the back surface, a first electrode 10 and a second electrode 11 are arranged as shown in FIG.

An electrical circuit diagram used in a treatment device having such a configuration is shown in FIG. 3. In the same figure, an oscillation circuit 20 is provided, and this oscillation circuit 20 generates a low frequency signal of, for example, 3 Hz (which can be made variable), and this signal is increased in thickness via a transformer 21 and guided to a piezoelectric element 22. This causes the piezoelectric element 22 to mechanically vibrate according to the oscillation frequency. The electrode 22a of this piezoelectric element 22 is connected to the electrode 11 shown in FIG.
b is connected to ground and corresponds to electrode 10 in FIG. Further, on the secondary side of the transformer 21, a neon tube 23 corresponding to the lamp 5 in FIG. 1 and a resistor R are connected in parallel thereto. Furthermore, a battery 2 made of nickel cadmium is placed on the primary side of the oscillation circuit.
4 and a battery 25 corresponding to the solar cell 4 in FIG. 1 are connected in parallel. "The piezoelectric element 22 and the electrode 10,
11 is illustrated in detail in FIG. 4, one end of the piezoelectric element 22 is connected to the electrode 10 (corresponding to electrode 22b in FIG. 3), and the other end is connected to the electrode 11.
(corresponding to the electrode 22a in FIG. 3).
In addition, what is indicated by the reference numeral 30 in FIG. 4 is an insulator. In such a configuration, when the switch 2 is turned on, the oscillation circuit 20 generates a low frequency signal, which is increased in thickness via the transformer 21 and causes the piezoelectric element 22 to mechanically vibrate. For example, when the electrode 10 is applied to a person's skin or a pot, and the power source is activated, the electrode 10 makes minute vibrations due to the piezoelectric element 22, and this vibration is transmitted to the inside of the person, making it possible to obtain a good treatment device. . In this case, the piezoelectric element also serves as a sound source,
Generates a pleasant low frequency sound. Also, electrodes 10 and 1
When both 1 are brought into contact with the human skin, a weak pulse current based on a piezoelectric element flows as is well known, which moderately stimulates acupuncture points, nerves, or muscles to provide even better treatment. becomes possible.

Furthermore, when the electrodes 10 and 11 are placed near the pot, the resistance at the pot becomes low and the electrodes 10 and 11 become conductive, thereby turning off the neon tube 23. It also becomes possible to detect their presence.

Further, according to the present invention, since the solar cell 25 is incorporated, there is no need to replenish or change the power source together with the normal battery 24, and the device can be operated at all times. It is also possible to charge the nickel-cadmium battery 24 with this solar cell.

In addition to the shapes shown in FIGS. 1 and 2, the therapeutic device according to the present invention may have various designs such as a lipstick container shape or a pencil shape.

In this way, in the present invention, a display tube that changes the display state when the resistance between the first and second electrodes of the piezoelectric element becomes low is connected in parallel to the piezoelectric element. The low resistance part of the object can be detected by the change in the display state of the display tube when the object comes into contact with the low resistance part of the object, and therefore the presence of acupuncture points on a person can be easily detected.

Further, in the present invention, a signal with increased thickness is applied between the first and second electrodes of the piezoelectric element to vibrate the piezoelectric element at a frequency corresponding to the low frequency signal, and
The piezoelectric element can vibrate and send a weak current to the object that comes into contact with the electrode, so by applying the piezoelectric element to the acupuncture points on the human body, it is possible to give appropriate stimulation to the acupuncture points, which can improve health and improve health. It becomes possible to enhance the beauty effect. Therefore, by applying the electrodes of the piezoelectric element to pressure points, beauty effects and health promotion can be measured, and in some cases, it is also possible to mainly enhance the beauty effects by cutting off the current.

Furthermore, since this invention uses solar cells, it has a semi-permanent lifespan, is small and lightweight, and has low power consumption.Furthermore, the piezoelectric element makes it possible to obtain a stable sound pressure and a good sound source. Become.
