The purpose is to ensure safety in use by eliminating electrical shock caused by handling by children.

Hereinafter, the present invention will be explained based on drawings showing embodiments thereof.

In FIG. 1, 1 and 2 are a main casing and a lower casing constituting a circular thin casing, 3 is a printed circuit board having an electronic circuit 4 that generates electric waveforms for treatment, and 5 is a printed circuit board for electronic circuit 4. A driving battery power source, 6 is a storage section provided in the lower casing 2 and stores the battery power source 5, 7 is a lid provided in the main casing 1 and closes the battery power storage section 6, 8 is the above-mentioned battery power source; This is a knob for adjusting the output of the electronic circuit 4 provided on the printed circuit board 3.

The printed circuit board 3 is sandwiched and fixed between the main housing 1 and the lower housing 2 that constitute a circular thin housing, and the output adjustment knob 8 is connected to the output regulator 9. engaged and integrated.

The main casing 1 and the lower casing 2 are tightly fixed by sandwiching the printed circuit board 3 therebetween and tightening them with screws 11 via a rubber ring 10.

In addition, a large diameter rubber ring (not shown) is inserted into the outer periphery of the mating parts of the main housing 1, the lower housing, and the lower housing 2 to prevent water from entering from the sides of the housing. .

Figure 2 shows the outer components of the integrated thin case, with reference numerals 12 and 12' representing a pair of output electrodes, and output coupling wires 13 and 13' being connected to the back surface of the pair of output electrodes. .

A pair of hydrous treatment electrodes 14.14' are made of polyvinyl formal resin and are pressed against the output electrodes 12.12', respectively.

Reference numeral 15 denotes an electrode holding member that holds the hydrous treatment electrodes 14 and 14';
．． A pair of windows 16 and 16' are provided to expose the windows 14', and protrusions 17.16' are provided at opposing positions on the outer peripheral surface.
17' is provided.

Further, peripheral frame-shaped ribs 18, 18' are provided on the outer circumference of the lower housing 2 constituting the circular thin housing, and the ribs 18, 18' of the brackets are provided with the electrode holding member 15. A notched hole 19.19' is provided in which the provided projection 17.17' fits.

Furthermore, the lower housing 2 is provided with holes 20, 20' through which the output coupling wires 13.13' of the output electrodes 12.12' are passed.

Said output electrode 12.12' has its output coupling line 13.13
' is passed through the hole 20.20' of the lower housing 2, and the end of the output coupling line 13.13' is coupled to the output of the printed circuit board 3 having the electronic circuit 4.

In addition, the output electrode 12.12' is inserted into the inner side of the peripheral frame-shaped glue 118, 18' provided on the lower housing 2, and the output electrode 12.12' is inserted into the pin 21.21' provided on the lower housing 2 through the hole 22.22'. are fitted together and adhered to the lower housing 2 with an adhesive to seal the holes 20 and 20' of the lower housing 2.

The output electrode 12.12' adhered to the lower housing 2 is electrically connected to the hydrous treatment electrode 14.14' by being pressed from the outside, and the electrode holding member 15 is connected to the protrusion 17.17.
The hydrous treatment electrode 14.14' is retained by fitting and attaching the electrode 14.14' in the cutout hole 19.19'.

By having the above structure, the output electrode 12.1
Even if moisture leaks from the hydrous treatment electrode 14.14' pressed against the output electrode 12.2' during use of the treatment device, the output electrode 12.
Since the outside of the lower housing 2 is sealed by 12', it is possible to prevent moisture from entering the inside of the lower housing 2.

Furthermore, since the electrode holding member 15 of the hydrous treatment electrode 14.14' pressed against the output electrode 12.12' is removably attached to the lower housing 2, it is extremely difficult to replace or clean it. It can be done easily.

On the other hand, as shown in FIG. 3, the electrode holding member 15 is provided with protruding frames 23, 23' at the center and both sides of the back surface to separate leakage water from the hydrous treatment electrodes 14, 14'. There is.

This makes it possible to prevent leakage current between the electrodes due to the presence of leakage water between the hydrous therapeutic electrodes 14, 14'.

FIG. 4 shows the lower housing 2 at different perspective angles, and shows notched holes 19 provided in the peripheral frame-shaped ribs 18, 18' and engaged with the protrusions 17 and 17' of the electrode holding member 15. ．．
19'.

FIG. 5 shows the outer components of the integrated thin casing, and only the points that are different from FIG. 2 will be explained.

That is, FIG. 5 shows the hydrous treatment electrode 14 of FIG.
In place of 14', a pair of storage sheets 24, 24' are provided which cover the output electrodes 12, 12' in an insulating manner.

This storage sheet) 24.24' is, for example, vinyl chloride,
This storage sheet is made of an insulating resin sheet such as polyester, and the electrode holding member 15 is attached to peripheral frame-shaped ribs 18, 18' provided on the lower casing 2.
24.24' is a pair of output electrodes 12.1.
2' to prevent direct exposure of this output electrode 12.12'.

As a result, even if there is unexpected contact with the human body when treatment is not required, or if a child who is not involved in low-frequency treatment is exposed to the electric current, they will not feel the current shock, and as a result, it will be safer to use. It is something that can be done.

As described above, according to the present invention, a pair of output electrodes are disposed outside the housing, and when treatment is not required, a pair of insulating storage sheets are installed in place of a pair of hydrous treatment electrodes. Since the treatment electrodes are attached using the treatment electrode holding member, the pair of output electrodes are insulated and covered by the storage sheet, and as a result, there is a risk of unexpected contact with the human body when treatment is not required, and low frequency Even if a child who is not involved in the treatment is given the electric current shock, they will not feel the electric shock, and therefore safety in use can be easily ensured with a simple configuration.
