As shown in FIG. 8, the pressing member 3 has a pressing surface 3a whose upper surface is curved upward, and has a pressing surface 3b at the front end which comes into contact with the impact portion of the piezoelectric element unit. Further, at the upper rear end of the pressing member 3, an engaging portion 3 that engages with the rear end edge of the opening 2a of the lid body 2 is provided.
c is formed, and an engaging portion 3d that engages with the front edge of the opening 2a is formed at the upper front end.

As particularly shown in FIG.
b, and is fixed to the base 1 in an obliquely upwardly inclined state. Then, the conductor 5 connected to the positive side of the piezoelectric element unit 4 is connected to the contact portion 1c.
The leading end of the conductive wire 5 is positioned at the lower end opening of the through hole 1d, and the terminal 6 connected to the negative side of the piezoelectric element unit 4 is inserted through the terminal insertion hole 1e. , the tip portion is exposed on the outer peripheral surface of the contact portion 1c.

A metal circular tube 7 is fitted into the contact portion 1c, and the tip of the terminal 6 is in contact with the inner circumferential wall of the circular tube 7.

The lid body 2 has the engaging protrusion 1 of the base 1 in the fitting recess 2b.
f are respectively fitted, and the engagement grooves 2c on the inner wall of the tip end and the inner wall of the rear end are engaged with the locking protrusions 1h of the base 1, thereby being locked to the base 1. .

The pressing member 3 has a pressing surface 3a that is connected to the opening 2 of the lid body 2.
is exposed to the outside from a, and is attached to the lid body 2 so that it cannot fall off outward by engaging the engaging portions 3d and 3c with the front edge or the rear edge of the opening 2a, respectively. . And the pressing surface 3b of the pressing member 3
is brought into contact with the head of the impact portion 4b of the piezoelectric element unit 4, and the tip of the pressing member 3 is biased toward the outside of the lid 2 by a spring built into the piezoelectric element unit.

The base 1, the lid 2, and the pressing member 3 are all made of non-conductive synthetic resin.

As shown in FIG. 3, in the electrotherapy device, when the pressing surface 3a at the tip of the pressing member 3 is pressed downward (arrow A), the leading end of the pressing member 3 is centered around the engaging portion 3c at the rear end. As a result, the pressing surface 3b presses the impact portion 4b of the piezoelectric element unit 4 and pushes it into the main body as shown by the chain line in FIG. A high voltage current is generated, and a discharge occurs between the tip of the conducting wire 5 and the tip of the metal circular tube 7 at the tip of the contact portion 1c.
Note that when the pressure of the pressing member 3 is released, the impact portion 4b is
returns to its original position, and along with this, the pressing member 3 returns to its original position.

When the above-mentioned electric therapy device is used by pressing the contact portion 1c against the skin, especially acupoints, the nerves are stimulated by the high-voltage electricity discharged toward the skin, resulting in effects similar to those of firmness treatment, for example. It can treat stiff shoulders, neuralgia, etc.

Note that since the base 1 and the lid 2 are engaged without using adhesive, disassembly is also easy. As a result, the ceramic inside the piezoelectric element unit 4 is vulnerable to external shocks, and even if the piezoelectric element unit 4 is damaged due to charge accumulation due to blank firing, it can be easily replaced. It is possible.

As mentioned above, this device can easily obtain the same therapeutic effect as firmness treatment using electrical stimulation using a simple device, and since it has a simple structure and is made of synthetic resin, the product price is low. It has various excellent effects such as being able to reduce costs, and since it is assembled without the use of adhesives, it is easy to disassemble, making repair and replacement of piezoelectric element units, etc. very easy. It is something.
