Description

[Detailed description of the invention] This invention relates to a brush that is implanted with magnetic bristles to enable magnetic therapy.

BACKGROUND ART Magnetic therapy has been known for treating diseases by applying a magnetic field to living bodies, pathways, and acupuncture points. One type of magnetic therapy is a pasting method in which magnet pieces are applied and fixed directly or indirectly to the patient's skin using adhesive tape, cloth or resin bands, or the like. For example, by placing a piece of magnet directly on your head,
Alternatively, you can sew a piece of magnet onto a fabric hat, then
There is a device that can be used to treat diseases such as hypertension by applying a magnetic field to the hole in the head.

However, with this method of attachment, it is necessary to apply the magnet piece directly to the head or to wear a hat with the magnet piece sewn on, which is not only troublesome but also difficult to wear in the summer. There was a problem with sweating when it was hot.

Therefore, in view of this problem, there was a strong demand for something that would allow a magnetic field to be applied to the hole in the head without directly applying a magnet piece or wearing a hat.

Therefore, in order to realize this request, a magnet was installed on the inner surface of the body that was molded integrally with the handle, and a storage lid was attached to the body so as to cover this magnet, and insertion holes were formed distributed in the storage lid. Magnetic bristles are inserted through the holes, and the opposing sides of the magnet and the bristles are made of magnetic poles of the same polarity, so that the bristles move elastically due to the repulsive force of the magnet. A brush was proposed that could also be used for magnetic therapy.

However, with a device in which magnetic bristles are simply fixed, it is difficult to fit the tips of the entire bristles to the scalp during brushing, and the magnetic therapeutic effect cannot be expected to be that great. .

Therefore, in the present invention, magnetic bristles are planted in the transplanted part, and an elastic body is used in the transplanted part so that the tips of the bristles fit against the scalp during brushing, and the bristles are made to slide freely in the axial direction. With this structure, the magnetic treatment effect can be efficiently exerted by fitting the hair to the scalp during brushing.

Hereinafter, this invention will be explained with reference to the drawings. FIGS. 1 and 2 are drawings showing a conventional example.
In this drawing, numeral 2 is a hairbrush;
This hairbrush 2 includes a handle 4 and a body 6 extending longitudinally from the handle 4, which are integrally molded from a suitable material such as resin, wood, or metal. A flocked portion 8 is formed inside the body 6.
The bristles 8 are made of a flexible elastic member such as rubber so that the bristles 10 are elastically fitted to the scalp during brushing. A countless number of bristles 10 are implanted in the bristles 8, and the bristles 10 are magnetic and can be used for magnetic therapy during brushing.

That is, each of the bristles 10, 10... has a T-shaped retaining part 12 at one end, and is preferably made of spinodal decomposition type semi-hard material of Fe-Cr-Co alloy with high plastic workability. Or, it is composed of a hard permanent magnet. This permanent magnet magnetizes the bristles as a whole into a large number of poles in the longitudinal direction. In this embodiment, the magnetic poles of all the bristles are aligned to the same polarity to strengthen the penetrating power of the magnetic lines of force, and to It is best to have a magnetic force of 500 to 2000 Gauss or more.

Hereinafter, a method for manufacturing the bristles 10 used in this invention will be explained with reference to FIG.

As shown in Fig. 3, raw materials for Fe-Cr-Co alloy spinodal decomposition type magnets are melted (process), agglomerated (process) is performed to obtain an ingot, and this ingot is hot-processed (process). For example, 1~2mm
φ rod and annealed at a temperature of 800 to 1200℃ (process)
After that, one end is forged into a T-shape and plastically worked (process) to draw the wire to a predetermined diameter, followed by solution treatment (process) if necessary, and isothermal magnetic field treatment (process) at 630 to 680°C. The bristles are then subjected to an aging treatment (step) in which the temperature is successively lowered in several steps or continuously to 600 to 540° C., and then magnetized (step) is performed to obtain magnetized bristles.

Figure 4 shows 23% Cr, 15% Co, 23% Cr, 15% Co,
This shows the relationship between the mechanical properties (elongation, tensile strength, Vickers hardness) and annealing temperature of a spinodal decomposition type permanent magnet with a composition of 2% V, 0.3% Ti and residual Fe (both weight %). It is clear that it has good workability and toughness. When using the bristles 10 as a brush as shown in FIGS. 5 and 6, which will be described later, they may be directly polished and used, but the surface may be coated with a resin such as polycitrafluoroethylene or painted. Alternatively, it is also possible to use a material coated with various types of plating, such as noble metals, or a material coated with ceramics. Further, the bristles 10 do not need to be made entirely of a permanent magnetic material, but only a portion of the rear end, that is, the retaining portion 12 or the vicinity thereof, is made of a permanent magnetic material having a magnetic pole in the axial direction, thereby making the brush portion on the tip side A ferromagnetic material such as a piano wire may be mechanically bonded or welded, or may be coated with a resin. If the magnetic bristles have the latter configuration, the magnet at the rear end need not be a magnet that is mechanically plastically workable, and may be, for example, an alnico magnet.

Next, the effect will be explained.

When using a magnetic hairbrush, as you brush, the tips of each bristles fit into the scalp, and the holes on the head receive a magnetic field, which relieves long-term tension on the nerves that causes hypertension. As a result, it may have a therapeutic effect on symptoms such as dizziness and headaches. Also, since hemoglobin in the blood is favorably affected by magnetic fields, it may improve blood circulation and reduce gray hair and hair loss. It is preferable that an effect such as a reduction in hair loss can be expected, and that such an effect can be simultaneously produced as the hair is brushed. The brush of the present invention is also useful as a scrubber or brush for brushing the skin of the limbs, chest, abdomen, and back.

5 and 6 show an embodiment of the invention.

In this embodiment, a body 14 and a storage lid 16 made of an elastic material having insertion holes for inserting a large number of bristles 24 made of a magnetic material, which will be described later, form a storage chamber 18 as a bristle-planting section. A pair of magnet pieces 20 and 22 housed in the magnet pieces 20 and 22 are repelled from each other to make the permanent magnet or ferromagnetic bristles 24 extending from one of the magnet pieces 22 magnetized, and the bristles 24 are urged to move. be.

That is, a large number of repulsion magnet pieces 20 are planted on the inner surface of the body 14, and the tips of the magnet pieces 20 protrude alternately with different polarities. Further, a cup-shaped solid or flexible storage lid 16 is removably and elastically engaged with a groove 26 formed on the inner peripheral edge of the body 14, thereby forming a storage chamber 18 as a flocked portion inside. There is. A repulsion magnet piece 22 is housed in the housing chamber 18, and bristles 24 extend from the magnet piece 22, and the bristles 24 pass through the loose insertion hole 27 of the housing lid 16 in a freely sliding manner in the axial direction. There is. bristles 2
4 has at its center an iron needle bar 30 which is fitted into the hole 28 of the repelled magnet piece 22 and attached by other mechanical means or various welding methods, and the periphery of this needle bar 30 is covered with resin. ing.

According to the brush of this embodiment, the pair of magnet pieces 2
Since the bristles 24 expand and contract against the repulsive force of the magnets 20 and 22, they fit well on the scalp and provide soft and comfortable stimulation.
may be one that cannot be plastically worked.

In addition, in the second embodiment, the housing chamber 18 is formed by the body 14 and the housing lid 16, but instead of forming a housing chamber, a solid housing lid is used, and the bristles are The insertion hole may be formed only in the portion where the slider slides.

That is, the surface portion of the storage lid has an insertion hole large enough to allow the linear portion of the bristles to slide, and the hole is large enough to allow the T-shaped retaining portion to slide in the portion corresponding to the axial direction of the bristles inside the storage lid. Similar effects can be obtained even if the structure is configured such that an insertion hole is formed.

It goes without saying that this invention is not limited to the above-mentioned embodiments, and can be modified in various ways. For example, the bristles and body of a brush for pine surge may be mixed with minute particles of the aforementioned various types of permanent magnets, permalloy, etc. during resin molding. Further, the brush of the present invention can also be used as a toothbrush for gingival pine surge.

As is clear from the above description, according to this invention, in a brush having a body etc. integrally molded with a handle, a flocked part is formed, and this flocked part has the following features:
The brush is made with magnetic bristles, so
Eliminates the hassle of attaching magnetic pieces directly or indirectly to the head exclusively for magnetic therapy,
It fits well on the scalp during habitual brushing, receives a magnetic field on the head and has a positive effect on the nerves and blood, activating it, making magnetic therapy excellent for treating gray hair, hair loss, and diseases such as hypertension. There is an effect that can be obtained.

Note that there is no problem in using the brush of the present invention as a brush for animals such as dogs, cats, horses, and cows.
