Abstract

PROBLEM TO BE SOLVED: To brush a narrow part or a complicated part tends to be difficult and insufficient because a gripping part and a brush part are integrated and have the same operation in a conventional brush. In particular, many toothpaste methods have been proposed for brushing teeth, but many people suffer from caries, gingivitis, and alveolar pus leakage due to insufficient brushing.
SOLUTION: A brush part or a grip part having a cylindrical insertion shaft with a protrusion, and a grip part or brush part having a hollow cylinder having a curved groove or a cut-in hole on an inner peripheral wall, the protrusion being the groove or When the gripping part moves back and forth, the brush part moves little or stops due to friction and pressure with the object to be treated and the surroundings when the gripping part moves back and forth. At this time, the protrusion moves along the groove or the cut hole. Since the groove or the cut hole has a curved shape, the reciprocating motion of the gripping portion is converted into the circumferential motion or torsional motion of the brush portion by the movement of the protrusion, and various brushing can be performed.

Description

  The present invention relates to a brush that improves brushing effects such as cleaning, painting, and tooth brushing by a mechanism that converts the reciprocating motion of the grip portion in the axial direction into the vertical circumferential motion of the brush portion.

  In conventional brushes, the gripping part and the brush part are integrally formed, so that the movement of the gripping part is transmitted to the brush part as it is, and if the processing surface is in a narrow place or has a complicated shape, washing, Brushing such as painting and cleaning is difficult, and it is difficult to obtain a sufficient effect. Especially for toothbrushing, the shape of the teeth and gums are complicated and the oral cavity is narrow, so many toothbrushing methods such as the rolling method, scraping method, bath method, and Fornes method have been proposed. Despite this, patients continue to suffer from tooth decay, gingivitis, and alveolar pus leakage due to inappropriate brushing.

  As a brush that does not integrally mold the brush part with the grip part, the toothbrush of JP-A-2000-116438 can be seen, but the movement of the brush part is because the shape of the cut part of the grip part is collinear with the direction of the toothbrush body. The movement of the brush part is vertical and the same as the direction of movement of the gripping part, but it is devised to be smaller than the movement of the gripping part, but the brush part cannot move circumferentially, and the movement of the gripping part is in a different direction It cannot be converted.

  As an example of changing the movement direction of the brush, there is a special table 2004-503319 as a toothbrush accompanied by a movement conversion from the vertical direction to the horizontal direction, but in the present invention, the gripping part and the brush head are formed integrally, It is a structure in which a large number of brushes planted in a ring shape are attached to the brush head at a predetermined angle, there is no change in the direction of movement of the brush head itself, and only the attached ring-shaped brush moves in the lateral direction This is different from that in which the movement direction of the brush portion itself is changed in conjunction with the movement of the gripping portion of the present invention. The invention has a complicated structure, and it is difficult to supply a toothbrush that is inexpensive.

Problems that the device tries to solve

  In conventional brushes in which the brush part and gripping part are integrally molded, the movement direction of the gripping part and the movement direction of the brush part are the same, so brushing from multiple directions, such as when cleaning narrow or complex parts Tends to be difficult and insufficient brushing. In particular, in the case of tooth brushing, although many tooth brushing methods have been proposed, for many reasons, many patients suffer from diseases such as tooth decay, gingivitis, and alveolar pyorrhea due to insufficient tooth brushing.

  In view of such problems, the present invention does not require any special device or power, and gives the brush part a movement different from the movement direction of the gripping part due to the movement of the hand. The purpose of the present invention is to provide a brush that can be efficiently cleaned at a low cost, and a toothbrush that can be cleaned in the oral cavity more efficiently and has less unpolished material.

Means for solving the problem

  A brush part having a cylindrical insertion shaft provided with a protrusion, and a grip part having a hollow cylinder with a curved groove or cut hole formed in an inner peripheral wall, and the protrusion of the insertion axis of the brush part is the grip part. When the gripping part reciprocates back and forth in a brush in which the insertion shaft of the brush part and the gripping part are slid together, the object to be processed and the surroundings are inserted. The movement of the brush part is less than that of the gripping part or stops due to friction and pressure. At this time, the insertion shaft-like protrusion smoothly moves along the groove or the cut hole of the inner peripheral wall of the hollow cylinder, so that the difference between the movement amount of the gripping part and the movement amount of the brush part corresponds to the curve of the groove or the cut hole. The protrusion moves along. In the present invention, since the groove or the notch hole is provided in a curved shape, the reciprocating motion of the gripping portion can be converted into the circumferential motion or torsional motion of the brush portion by the movement of the protrusion of the insertion shaft.
