Description

  This device not only touches the teeth and gums to be brushed, but also easily penetrates into the teeth and the periodontium between the teeth and gums. A toothbrush that can easily remove plaque.

  A conventional toothbrush is formed of a handle portion gripped by a hand and a brush portion on the tip end side of the handle, and a large number of hairs for brushing teeth are implanted in the brush portion. The toothbrush handle is gripped by hand, the toothbrush is applied to the brush, the brush portion is placed in the palate, and brushed along the gums and gingiva to remove bites and plaque.

  In conventional toothbrushes, the brush part has been made slightly smaller to make it easier to move around the dentition and gums in the palate, and the brush tip is made thinner to make it easier to enter the gap between the gums and gums. There is something. In addition, there are some that are provided with an angle between the handle and the brush part and put in the palate for easy exercise. However, even with these toothbrushes, if the movement of the user's hand holding the handle is not appropriate, it cannot be polished sufficiently, and this method of moving the hand has not been easy.

  As conventional technology, in order to increase the interdental penetration of the toothbrush tip and to improve the contact comfort and the feeling of brushing, the hair bundle is made into a taper hair, and this taper hair is formed by cutting in a mountain. Is disclosed (for example, see Patent Document 1).

  In addition, a toothbrush has been developed in which the brush bundle is freely rotatable so that the brush tip is oriented in a direction that fits well into various irregularities (see, for example, Patent Document 2).

  Furthermore, a toothbrush for tooth cleaning has been proposed in which the brush portion of the toothbrush can be rotated by a rotation shaft with respect to the handle so that the entire dentition can be polished without changing the posture (for example, Patent Document 3). reference.).

  However, even with these toothbrushes, it is difficult to move the toothbrush through the palate at an appropriate speed, and the functions of these toothbrushes are not necessarily fully exhibited.

  This device is designed to change the brush part of the toothbrush to an appropriate movement while making the reciprocating movement to move the fingers gripping the handle rhythmically uniform when holding the handle of the toothbrush along the dentition and moving it left and right. An object of the present invention is to provide a toothbrush having a structure in which the tip of the toothbrush can be sufficiently inserted between the teeth and the gums and gums of the periodontal, and the toothbrush and plaque can be sufficiently scraped.

  The means of the present invention for solving the above problem is that in the means of claim 1, the brush portion 3 in which the brush bristles 4 are planted with respect to the portion of the handle 2 that grips the toothbrush 1 with the hand is arranged in the length of the handle 2 The toothbrush 1 is formed by engaging in a movable state with a play 8 in the direction.

  Further, according to the second aspect of the present invention, the play 8 described above is 3 to 5 mm longer than the length of the brush portion 3 with respect to the length of the shaft portion 5 of the handle 2 inserted through the shaft hole 6 provided in the brush portion 3. It is the toothbrush 1 of the means of Claim 1 formed.

  When brushing teeth, there are cases where the toothbrush is moved in the vertical direction between the teeth of the dentition and the gap between the teeth while the toothbrush is lightly pressed toward the teeth and gums, and may be moved left and right along the direction of the dentition. This toothpaste hand movement will move more than the length and width of one tooth. This is because the size of the hand to grip is extremely large compared to a single tooth, and there is too much difference between them, so it is naturally difficult to make fine movements. In such a case, the tip of the brush of the toothbrush does not sufficiently enter between the teeth or between the gums and gums, and moves with the toothbrush body. As a result, the bristles of the brush portion of the toothbrush inherently slip up without touching the teeth and touching plaque. Therefore, in such a case, the purpose of brushing the teeth is not achieved sufficiently, and the toothpaste and plaque accumulated between the teeth and between the gums and the gingiva can become decayed and calculus can be formed.

  On the other hand, the toothbrush of the present invention has axial play in the brush part and the handle part, so the brush part moves with a delay corresponding to this play, so it is more than the movement width of the hand. The width of the movement of the brush is reduced by the amount of play, and can be changed to fine movement. Furthermore, since the movement is delayed by the amount of play in time, the bristles of the brush part can enter between the teeth and between the gums and the gums. It can scrape out enough food and plaque. As described above, the present invention provides a play so that the movement of a large hand is replaced with a fine movement amplitude movement, and the movement of the brush is sufficiently spaced between the teeth and gums by giving time to the movement. It can be inserted into the gingiva and has an unprecedented excellent effect.

  The best mode of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a cross-sectional view showing a main part of the toothbrush of the present invention. FIG. 2 is a perspective view showing a main part of the toothbrush of the present invention. In these drawings, reference numeral 1 is a toothbrush, 2 is a handle, 3 is a brush part, 4 is a bristle, 5 is a shaft part, 6 is a shaft hole, 7 is a tip part, and 8 is play.

  The handle 2 other than the bristles 4 of the toothbrush 1 and the main body of the brush portion 3 are made of plastic. The brush portion 3 is formed at the tip portion side of the handle 2 that grips the toothbrush 1 with fingers, and has a rectangular shaft portion 5 with a thin diameter in the longitudinal direction, and the shaft portion 5 has a rectangular shaft hole 6 opened in the longitudinal direction. Through. Brush hair 4 is planted on one side of the brush portion 3. Since the shaft hole 6 of the brush portion 3 is square and the shape of the shaft portion 5 on the tip end side of the handle 5 is square, the brush portion 3 does not rotate around the shaft portion 5. The tip portion 7 of the shaft portion 5 is substantially the same size as the tip portion of the brush portion 3 rather than the shaft hole 5 so that the fitted brush portion 3 does not come off. The shaft portion 5 through which the brush portion 3 is passed is integrated by, for example, providing a hole in the handle 2 and fitting and bonding. Alternatively, the tip of the shaft portion 5 through the brush portion 3 is bonded to the tip portion 7 and integrated.

  Since the length of the shaft portion 5 thus formed is 3 to 5 mm longer than the shaft hole 6 of the brush portion 3, the length between the brush portion 3 and the handle 2 or the tip portion 7 at both ends of the shaft portion 5 is set. 3 to 5 mm of play 8 is formed. This play 8 allows the brush portion 3 to slide back and forth along the shaft portion 5.

  The usage method of the toothbrush 1 of this invention is demonstrated. A toothpaste is applied to the brush bristles 4 of the toothbrush 1, and the teeth are usually applied to the teeth and brushed. In this case, when moving the bristle 4 above and below the teeth, it is moved with fingers as in a normal toothbrush. By the way, when brushing or massaging the dentition or between the gums and gums or the gums, the toothbrush 1 is moved back and forth laterally along the dentition or between the gums and gums or along the gums. In this case, the finger moves back and forth in the normal way. By the way, the toothbrush 1 of the present invention has the play 8 between the brush part 3 and the shaft part 5, so that the back and forth movement is delayed by the play 8. In addition, the forward / backward vibration is narrowed by 3 to 5 mm of the play 8. Therefore, the movement time of the front and back of the toothbrush 1 is delayed by this play 8, and the brush hairs 4 are pressed between the teeth and between the gums and the gums during that time, and the scrapes and plaque are scraped sufficiently. You can start.

  Thus, the toothbrush 1 of the present invention can be implemented accurately without brushing the brushing of the teeth. Moreover, in the conventional toothbrush, it is necessary to train and always pay attention in order to brush the toothbrush while finely vibrating the toothbrush. However, the toothbrush 1 of the present invention has an advantage that brushing can be performed by naturally replacing the movements of the fingers with fine back-and-forth vibrations without special training.
