Conventionally, an interdental brush has been used for cleaning plaque attached to an interdental part. This interdental brush is a product in which a cleaning brush is fixed to the tip of a handle with a metal wire or the like, and in a case with little gingival retraction or a molar that cannot be directly seen, the cleaning brush is attached to the interdental portion without damaging the gingiva. Cleaning by inserting and inserting into the buccal and lingual directions with fine movement in the buccal and tongue direction requires skill, which often results in breakage of the interdental brush and damage of the papillary gingiva.

A cleaning brush unit including a brush in which a synthetic fiber is twisted and stopped on a metal torsion wire, and a ring-shaped crank wheel (for inserting an eccentric cam and sliding a slider) at the other end; A head member molded into a shape that is deformed into a two-dimensional or three-dimensional bent shape and passes through so that an arbitrary angle is formed with respect to the main body (the main body long axis direction), and is inserted into a slider that passes through the head member. An elliptical eccentric cam is fitted on the other end of the slider to slide the cleaning brush, which fits the inner circle of the crankwheel. An electric motor comprising a face gear, a motor provided with a spur gear for rotating the face gear to provide power, and a main body equipped with a battery for driving the motor and holding it with fingers during use. With the interdental brush, the cleaning brush of the electric interdental brush only needs to be inserted and held in the interdental portion in order to perform a piston movement (automatic cleaning movement) in the longitudinal direction by the power of the motor. Plaque control is possible without the need for a fine pull-in / pull-out movement of the fingers on the cheek-lingual side as in a conventional interdental brush. For this reason, even in cases with little gingival retraction or in molars where direct vision is not possible, plaque control is possible simply by inserting and holding a cleaning brush in the interdental area, which not only prevents damage to the interdental papillary gums, but also prevents Since unnecessary pressure is not applied to the brush itself or the brush portion and the body-joining portion, breakage of the interdental brush itself can be prevented.

It is possible to set the bending angle of the head member forming the outer shell from 0 degree to 135 degrees by setting the shape of the head member of the brush as a combination of a straight line, a bent shape having a radius of 5 mm or less, and a linear shape. Can be composed of Therefore, the head member (the linear portion and the first bent portion immediately adjacent to the cleaning brush) in the vicinity of the cleaning brush in the longitudinal direction is reduced in size, and the major axis in the cleaning brush in the longitudinal direction can be shortened. The cleaning brush can be easily inserted into the interdental portion of the molar part without interfering with the cheek or tongue.

By providing the mechanism of the above, the brush angle with respect to the main body long axis direction (main body long axis direction) can be arbitrarily set variably from the front teeth to the molar teeth according to the cleaning site in the oral cavity. The cleaning brush can be easily inserted into the interdental area from a direction that is easy to avoid and approach. Also, when there is crowding and the direction of insertion of the cleaning brush is regulated, the interdental brush can be easily inserted into the interdental area without damaging the interdental papillary gum by setting the brush angle in accordance with the interdental space buccal tongue penetration direction It becomes possible to insert into.

In the drawings, the portions denoted by the same reference numerals as those in the drawings represent the same components, and the basic configuration is the same as that of the conventional one shown in the drawings. However, the feature of this illustrated example is that
As shown in FIGS. 1 and 2, the power of the motor 9 rotates the face gear 6 fixed by the gear bearing of the main body 3 by the spur gear 8. This rotational power is transmitted to the eccentric cam 7 by the gear shaft 11 and is converted into a sliding motion parallel to the long axis direction of the main body by the crank wheel 5 fitted outside the eccentric cam 7 guided by the main body 3. The sliding motion of the crank wheel 7 is propagated to the slider 4 axially passing through the head member 2 and causes the cleaning brush 1 inserted at the tip to slide. At this time, the direction of the sliding motion parallel to the main body 3 of the crank wheel 5 is
It is set by the two-dimensional or three-dimensional bending shape of the head member 2 through which the elastic slider 4 passes. When the cleaning brush 1 is inserted into the interdental portion while gripping the main body 3 of the electric interdental brush in the illustrated example, the cleaning brush 1 slides by the driving force of the motor 9, and the cleaning brush is finely moved in the buccolingual direction by hand pressure. Automatically cleans interdental plaque in a stationary state without exercise.

Thus, the bending angle of the bending portion 13 of the head member 2 of the head member 2 forming the outer shell can be set in a range of 0 to 135 degrees. Therefore, the shape of the head member 2 can be constituted by a combination of a straight line, a bent portion 13 of the head member having a radius of 5 mm or less, and a straight portion 14 of the head member, and the long diameter 15 of the rear head member in the cleaning brush long axis direction (cleaning). The linear portion and the first bent portion in the immediate vicinity of the brush are reduced in size, and the major axis in the major axis direction of the cleaning brush is reduced. When inserting the head member 2 having the long diameter 15 of the rear side head member in the longitudinal direction of the short cleaning brush into the oral cavity and inserting the head member 2 into the interdental portion of the molar teeth, the tooth space is not pressed out along the occlusal plane without removing the cheek or tongue. Insert the cleaning brush 1 into the section.

With this, the cleaning brush angle with respect to the main body long axis direction (main body long axis direction) can be set arbitrarily according to the cleaning site in the oral cavity from the front teeth to the molars, and then the cleaning brush can be used while avoiding the cheeks and tongue. Insert into the space. If there is crowding and the insertion direction of the cleaning brush is regulated, the cleaning brush is inserted into the interdental portion with a variable setting in advance in accordance with the interdental space buccal tongue penetration direction.

The vertices are directed toward the insertion direction molded with synthetic resin or porous material, etc., which elastically deforms at the tip of the tooth, and the extraction direction opposite to the insertion direction. Four interdental insertion guide wings 18a (fins) that move in a pantograph-like manner are arranged in a general shape obtained by combining the conical shapes joined by the largest protruding portions 18b, and the interdental insertion guide wings 18a are fins. The interdental insertion guide at the end of the interdental insertion direction is integrated at the spherical head portion 17 and is fixed to the cleaning brush 1 by the interdental insertion guide and the metal torsion wire insert portion 19. When the cleaning brush is inserted, the interdental portion insertion guide spherical head portion 17 is dull because of the dullness of the gingiva, and the interdental portion insertion guide spherical head portion 17 of the cleaning brush 1 is moved to the adjacent tooth axial surface. When pushed into the trap formed by the prosperity of the tooth, the interdental insertion guide blade 18a is compressed and deformed into the shape of the interdental solid space, guides the cleaning brush 1 to the interdental part, and easily slides into the interdental part. Also, when the cleaning brush 1 is pulled out from the interdental portion, the interdental portion insertion guide blade 18a is compressed and deformed and can be easily extracted.
