Abstract

PROBLEM TO BE SOLVED: To provide an outward unprojecting, safe and easily manufacturable cleaning brush having variety in the cleaning direction by arranging a tip of a conductor inside a hair material extending in a radial shape to the four sides. SOLUTION: A tip part of wires 2 of a torsional brush is rolled in by a single turn or more to constitute a cleaning brush 1. Since the tip part of the wires 2 is rolled in, the wires 2 does not project outside, so that the cleaning brush is safe. Since a hair material 3 of a rolling-in part extends in a radial shape to the four sides, cleaning work can be performed in all directions. The hair material 3 is arranged only in the rolling-in part of the wires 2, and the other end side having no hair material 3 is extended in a straight line shape to form a grip 4 to be formed as an intraoral cleaning brush. Since a part of the hair material 3 is an almost spherical shape and expands in a radial shape, the hair tip is applied to all parts in the oral cavity to stimulate a mucous membrane to be efficiently cleaned.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a torsion brush for cleaning comprising a hair material sandwiched between two core wires, twisting the core wires and spirally arranging the hair material.

[0002]

2. Description of the Related Art Conventionally, a torsion brush formed by sandwiching a bristle material between two core wires, twisting the core wires and spirally arranging the bristle material has been known as U.S. Pat.
2. Description of the Related Art Scouring scissors which are bent in a letter shape and are connected at both ends of a cord are well known. This scourer has a problem that the end portion of the core wire is exposed and may be in contact with the object to be cleaned and may be damaged. Further, for example, for cleaning the oral cavity of a sick person such as a so-called bedridden elderly person, conventionally, there is no special device, and a toothbrush or a cotton swab is used. Cleaning of the oral cavity of bedridden elderly people is not only necessary for hygiene, but also attracts attention as stimulation by contact with the brush bristles improves blood circulation of the oral mucosa and provides good stimulation to the brain. ing. In view of such applications, toothbrushes are not suitable for sick people without teeth, and are not suitable for cleaning the entire oral cavity because they are implantable and have only one direction of hair. Swabs are less irritating and cannot be used repeatedly.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a safe and versatile cleaning direction in which the ends of the cords are arranged inside the bristle material extending radially in all directions so that they do not protrude outward. It is an object to provide a cleaning brush which is easy to manufacture.

[0004]

According to the present invention, in order to solve the above-mentioned problems, a cleaning brush is formed by winding one or more turns of the end portions of the core wires 2 and 12 of the torsion brush.
Since the end portions of the core wires 2 and 12 are entangled, the core wires do not protrude to the outside and are safe, and the hair materials 3 and 13 of the entangled portion extend radially, so that cleaning work can be performed in all directions. I can do it.

[0005] Further, when the bristle material 3 is arranged only at the portion where the core wire 2 is wound, and the handle 4 is formed by linearly extending the other end side without the bristle material 3, such as in the mouth. Suitable for cleaning space. When used for cleaning the oral cavity, the size is set so that it can be inserted. Since the portion of the hair material has a substantially spherical shape and spreads radially, it is possible to stimulate the mucous membrane by applying the hair tip to any part in the oral cavity and to wash it efficiently.

Further, a bristle material 13a having a longer bristle foot than the others is disposed at the end of the winding portion of the core wire 12, and the long bristle material 13a protrudes from the vicinity of the center of the winding portion in a direction perpendicular to the winding surface to be washed. When the brush 11 is used, the cleaning operation can be performed with a single brush by selecting the long part 13a and the short part 13b of the bristle material according to the application. In this case, if the bristle material 13a having long bristle feet is formed of a material harder than the other bristle material 13b, the central portion can be used as a substitute for Sasara.

[0007]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of an intraoral cleaning brush to which the present invention is applied, and FIG. 2 is a side view of the intraoral cleaning brush.

In the figure, a torsion brush 1, which is a brush for cleaning the oral cavity, sandwiches a bristle material 3 between two cores 2 (in the example shown, one folded at one end), and And the bristle material 3 is spirally arranged. The tip of the core wire 2 is spirally wound into about 1.5 turns. The bristle material 3 is arranged only at the portion where the core wire 2 is wound, and the other end without the bristle is a handle 4 extending linearly.
The length of the bristle material 3 is about 15 mm to 20 mm, and is set to a size suitable for insertion into the oral cavity and cleaning work. The bristle material 3 spreads almost equally in a ball shape in all directions. Although it is technically difficult to manufacture a brush with a bristle material spreading in all directions in an implanted structure, it can be manufactured extremely easily by involving a torsion brush. In the oral cavity, the hair material 3 comes in contact with all parts of the inner surface with substantially equal pressure, and removes dirt and stimulates the blood to promote blood circulation. Since the distal end of the core wire 2 is entangled inward and does not protrude outward, there is no danger of damaging the inside of the oral cavity, which is safe. If it is washed and disinfected, it can be used repeatedly.

3 to 5 show a brush for cleaning a cooking utensil or the like to which the present invention is applied. FIG. 3 is a front view, FIG. 4 is a side view, and FIG. 5 is a plan view of the brush before twisting a cord. FIG.

Referring to FIG. 1, a torsion brush 11, which is a brush for cleaning cooking utensils and the like, has a bristle material 13 sandwiched between two core wires 12 and twists the core wires 12 as shown in FIG. Lumber 1
3 are formed in a spiral shape. The core wire 2 is spirally wound into about 1.5 turns. A thick and hard bristle material 13a having a longer bristle foot than the others is disposed in a predetermined range of the leading end of the core wire 12 on the winding side, and protrudes from the vicinity of the center of the winding portion in a direction perpendicular to the winding surface. In the illustrated example, the length of the long bristle material 13a is about 45 mm, and the length of the other bristle material 13b is about 94 mm.

This brush is suitable for washing work of cooking utensils such as pots, and uses a portion of the long bristle material 13a in the center like a sasara, and uses the other parts in the same manner as a normal scourer. Note that a structure in which the bristle material 13a having a long bristle foot is protruded only on one side may be employed.

[0012]

As described above, according to the present invention, the cords 2, 12 are provided inside the bristle members 3, 13 extending radially in all directions.
It is possible to provide an easy-to-manufacture cleaning brush that is safe, does not protrude outward, and is safe and has various cleaning directions.
