Description

The present invention relates to a massage machine, and more particularly, to a portable massage machine having a high-potential generating circuit.

[Prior Art] As a portable massage machine of this kind, the present applicant has previously incorporated a high-potential generating circuit and disclosed a shade as a treatment section as described in Japanese Utility Model Application Laid-Open No. 61-184431. An electrode and a handle provided with a positive electrode on the handle are proposed.

In this method, when the user grips the handle portion and brushes or puts on the body surface, a high negative potential can be repeatedly applied to the skin surface via the brush portion. As a result, the potential distribution of the skin can be restored to normal, and the fatigued skin can be activated.

[Problem to be Solved by the Invention] Such a portable massage machine can activate a tired skin by applying a high negative potential, but in order to further reduce the degree of skin fatigue, or In order to sufficiently activate the inside of the skin (for example, a depth of about 5 mm from the skin surface), a more effective massage has been desired.

By the way, recently, a thermal effect by far-infrared rays has attracted attention. For example, there is a case where the body core is warmed up when entering a sauna or bath where far infrared rays are radiated. This is due to the fact that far infrared rays penetrate not only on the surface of the body but also inside, thereby increasing the temperature.

The present invention has been made for the purpose of enhancing the massage effect using the far infrared rays.

Configuration of the Invention The configuration of the present invention that achieves the above object will be described below.

[Means for Solving the Problems] The portable massage machine of the present invention includes a high-potential generating circuit, a treatment section is formed as a negative electrode of the high-potential generating circuit, and a handle of the high-potential generating circuit is provided on a handle.

In the case of a configuration in which a heat source is provided, the heat source can be realized by a heat storage material such as phosphate or water housed or attachable to the mixing member, or a heater such as barium titanate or mica supplied by an external power supply. .

When a conductive brush is provided on the surface of the mixing member, the conductive brush may be a composite fiber kneaded with carbon, sulfonate or polyethylene glycol, or an acrylic resin adsorbing monovalent copper ions. Alternatively, it can be made of an antistatic-treated nylon fiber or the like.

The mixing member is formed by mixing at least a synthetic resin, a conductive substance, and a far-infrared radiating substance. The conductive substance and the far-infrared radiating substance are desirably pulverized and mixed as finely as possible, and it is more desirable to use fine particles of about 8 to 10 [microns]. Also,
The far-infrared emitting material is sufficiently effective if the content is 5% or more.

Examples of the synthetic resin that is a main component of the mixing member include various resins such as a fluorine resin and an ABS resin in addition to a vinyl chloride resin.

Examples of the conductive substance include powders of carbon, nickel, silver, copper, and the like.

Examples of far-infrared radiating materials include cordierite, β-spodumene, aluminum titanate and other ceramics having a low coefficient of thermal expansion and heat resistance, and transition element oxide-based ceramics having a large coefficient of thermal expansion but a high emissivity (one example). As Mn
O2 60%, Fe2 O3 20%, CuO 10%, CoO 10%). These can increase the radiation intensity by increasing the temperature by providing a separate heat source. In addition, silicon carbide, Sb2O5

It emits far-infrared rays to the human body and heats the inside of the skin.

Example In order to further clarify the configuration and operation of the present invention described above, a preferred example of a portable massage machine of the present invention will be described below. FIG. 1 is a sectional view of a portable massage machine as a first embodiment of the present invention, and FIG. 2 is an electric circuit diagram thereof.

In the figure, A indicates a handle, and B indicates a head. The head portion B is elastically supported by the handle portion A via a metal leaf spring 1 covered with a soft vinyl chloride cover.

The handle A is placed in a case 2 formed of a synthetic resin.
As shown in FIG. 1, a high-potential generating circuit 3 and the like are incorporated, and a part of the case 2 is provided with a lid 5 for inserting and removing the dry battery 4. This lid 5 is made of conductive AB

On the other hand, the head portion B includes a head case 15 made of synthetic resin,
The treatment section 17 is screwed to the head case 15 with the leaf spring 1 interposed therebetween. The treatment section 17 has a shape in which a plurality of projections are formed on the front surface, and the projections have a conical shape with a rounded tip. In addition, treatment section 17
Is formed by kneading powder of 20% carbon and 10% zirconia ceramics into 70% vinyl chloride as the main component. This zirconia-based ceramic has the characteristic of far-infrared emissivity shown in FIG. 3 (measured at a temperature of 79 ° C.). The zirconia ceramic powder used in this embodiment is fine particles of about 8 to 10 [μm]. Since the treatment section 17 has conductivity, it is electrically connected to the anode of the high potential generation circuit 3 via the leaf spring 1.

The leaf spring 1 functions as a conductive path from the high-potential generating circuit 3 to the treatment section 17, and as an original function of the leaf spring,
Good putting is realized by grasping the handle part A and hitting the head part B to the head in small increments.

Next, the configuration and operation of the high potential generation circuit 3 will be described. As shown in FIG. 2, the high potential generation circuit 3
