detailed description

Hereinafter, preferred embodiments of the present utility model will be described in detail with reference to the accompanying drawings. First, reference numerals are attached to components in each drawing, and care should be taken to have the same symbols as much as possible even if the same components are shown in different drawings. In addition, although the preferable Example of this invention is demonstrated below, the technical thought of this invention is not limited or limited to this, Of course, it can change and implement variously by those skilled in the art.

Referring to FIGS. 1 and 2 , an interdental brush 100 according to an embodiment of the present invention includes a toothbrush body 110 , a toothbrush head 120 and a connecting member 130 . By fixing the toothbrush head 120 equipped with a wire 121 and a plurality of toothbrush hairs 122 fixed to the outer peripheral surface of the wire 121 to the toothbrush main body 110, and a plurality of wire segments connecting each end of the toothbrush hair 122 form a triangle, it can be easily inserted and used. The patient's gums and the area between the two teeth connected to the gums, and improve the plaque removal efficiency.

The toothbrush main body 110 may be formed in a long rod shape extending in the vertical direction, but is not limited thereto, and may be formed in a shape that is easy for the user to hold. The toothbrush head 120 can be fixed on the upper peripheral surface of the toothbrush main body 110 .

Referring to FIG. 1 to FIG. 3 , the toothbrush head 120 may include a wire 121 , toothbrush bristles 122 and a hanging part 123 .

The wire 121 can be fixed to the toothbrush main body 110 through the connection member 130 . At this time, the angle θ formed by the wire 121 fixed to the toothbrush body 110 and the toothbrush body 110 (an imaginary line A horizontal to the toothbrush body 110 (vertical direction in FIG. 3 )) is preferably an acute angle. In particular, the angle formed by the wire 121 and the toothbrush body 110 is preferably 74 degrees or more and less than 90 degrees.

In this way, the reason why the angle formed by the wire 121 and the toothbrush body 110 should be 74 degrees or more and less than 90 degrees is that when the user cleans between the teeth, the wire 121 is easily inserted between the teeth, and the wire 121 and the toothbrush body 110 are formed. When the formed angle is more than 74 degrees and less than 90 degrees, the user has no inconvenience in using the interdental brush 100. However, when the angle formed by the wire 121 and the toothbrush main body 110 is an obtuse angle of more than 90 degrees In order to insert the wire 121 between the teeth, the user needs to open the mouth relatively wide, or it is difficult to insert the wire 121 between the teeth from the inner side of the teeth. When the angle formed by the wire 121 and the toothbrush body 110 is less than 74 degrees, the toothbrush body 110 may hang on the user's chin or cheek when cleaning the incisors.

In addition, 74 degrees, which is the minimum angle formed by the wire rod 121 and the toothbrush main body 110, was calculated as follows.

The minimum angle of 74 degrees is the minimum angle at which the toothbrush main body 110 does not hang on the user's chin or cheeks when cleaning the incisors. and the maximum length from the user's front teeth to the chin.

Usually, the length from the user's incisors to the chin does not exceed 10 cm, therefore, the maximum length is set at 10 cm, and the thickness of the connecting member 130 is properly set at 1.7 cm-2.61 cm.

Then, the minimum angle was calculated by substituting the maximum length and thickness into Equation 1 below.

<Formula 1>

Minimum angle＝tan ^-1 (Lm/T)

In Equation 1, Lm is the maximum length from the user's incisors to the chin, and T is the thickness of the connecting member 130 . When 10 is substituted into Lm of Equation 1, and 2.61 is substituted into T, 75 degrees can be calculated. When 10 is substituted into Lm of Equation 1, and 1.7 is substituted into T, 74 degrees can be calculated. Therefore, the minimum angle can be 74 degrees.

In this way, if the wire 121 is fixed to the toothbrush main body 110 at an acute angle, when cleaning between the teeth, it becomes easy to insert between the teeth from the inner side of the teeth when the mouth is opened smaller than before, and The inconvenience that the toothbrush main body 110 hangs on the chin, the cheek, etc. can be eliminated.

The first toothbrush bristles 122a may extend in a first direction (direction e in FIG. 2 ) based on the wire 121 .

The second toothbrush bristles 122b can be formed by extending in a second direction (direction f in FIG. 2 ) based on the wire 121 .

The third toothbrush bristles 122c may extend in a third direction (direction g in FIG. 2 ) based on the wire 121 .

The respective lengths of the first, second, and third toothbrush bristles 122 a , 122 b , and 122 c are the same as each other, and are longer than the lengths of other toothbrush bristles among the plurality of toothbrush bristles 122 .

Accordingly, when the toothbrush hair 122 is viewed with the wire 121 as the central axis, the plurality of line segments B connecting the respective ends of the toothbrush hair 122 form a triangular shape. The interdental brush 100 using such triangular bristles 122 can be easily inserted into the user's gums and the area between two teeth connected to the gums, and can improve the removal efficiency of dental plaque.

In addition, a hook portion 123 may be provided at one end of the wire 121 in the opposite direction of the toothbrush main body 110 . When the wire 121 moves back and forth between the teeth of the user, the hanging part 123 prevents the wire 121 from completely detaching from between the teeth, and prevents the wire 121 from being inserted between the teeth again, thereby improving the convenience of brushing teeth of the interdental brush 100 sex.

The connection member 130 may have a conical shape.
