The present invention relates to a rotary toothbrush having a circular brush body.

This invention is a common left. When brushing in the right direction, the rotatable circular brush is in contact with the skin of the mouth, and the brush surface provides the effect of contacting the teeth in the up and down directions. In particular, the present invention provides a smoother rotation of the brush body. In order to provide a plurality of friction protrusions in the eastern part of the brush body to be in contact with the mouth skin is the subject of the present invention.

The most ideal method for brushing is to clean the toothbrush in contact with the teeth in the longitudinal direction, which is the grain direction of the teeth, so that the plugs and dirt stuck in the teeth can be effectively removed and cleaned. It is a well known fact, but most people are not living up and down brushing.

Prize. Downward brushing left unsuccessful on the other hand. The most fundamental reason why right-hand brushing is habitual is that most toothbrushes are composed of brush and handle side by side. The left side of the toothbrush rather than moving up and down. Moving in the right direction is much more natural.

To solve this fundamental problem, only brush and teeth can be moved by moving the handle from side to side. A rotating toothbrush (application number. Utility Model Application No. 87-19458, Utility Model Application No. 89-1671) to be in contact with the downward direction was previously filed by the present applicant.

The above design is left. When brushing in the right direction, the circular rotating brush body comes into contact with the skin inside the mouth and is rotated by its frictional force. It provides the effect of contacting downward. In the above design, it is natural that the cleaning effect of the teeth is improved as the rotation of the brush body is desired, and it has come to recognize the necessity of a smooth rotation of the brush body than the use review result.

Accordingly, an object of the present invention is to improve the cleaning effect of the teeth by smoothly rotating the brush body by configuring a plurality of friction protrusions in the eastern part of the brush body to be in contact with the skin inside the mouth.

Hereinafter, the configuration of an embodiment of the present invention based on the accompanying drawings.

However, in the construction of the friction protrusion, which is the subject of the present invention, the fastening means between the circular brush body and the wooden body is not limited to any of the structure shown in the applicant's application and the configuration shown in the present application, and the shape of the friction protrusion And shape and size are not limited.

1 and 2 are external perspective views of an embodiment of the present invention, and FIG. 2 is in an upright state.

3 and 4 are front and bottom views of one embodiment, and 5 (a) and (b) are front and bottom views of a brush body in one embodiment, and FIGS. 6 (a) and (b) Is a front view and a bottom view of another embodiment brush body, and FIG. 7 is a cross-sectional view of the present invention.

In the present invention, the brush body cited a structure eccentric from the wooden body, but is not limited to this as described above.

As can be seen from the drawing, a fastening ring 6 in which shaft holes 7 are formed in the eastern part of the circular brush body 2 in which a plurality of brushes 1 are planted is formed, and a housing is formed in the shaft holes 7. (8) is forcibly fitted, the shaft 9 is formed on the wooden body 3, and the shaft 9 is fitted to the housing 8 so as not to be separated so that the brush body 2 is the wooden body 3 ), And a plurality of friction protrusions 5 are formed on the back of the brush body 2.

In forming the friction protrusion 5, FIG. 5 is a circular phenomenon formed on the back of the brush body 2 as an embodiment, and FIG. 6 is a friction protrusion in an arc shape on the opposite side of the brush body as another embodiment. (5) protruding structure.

Rotating toothbrush of the present invention gripping the handle (4) left. When brushing in the right direction, it rotates due to the frictional force generated by contact between the brush surface and teeth and the frictional force when contacted with the back of the brush body and the skin inside the mouth. That is, as shown in FIG. 7, the shaft 9 protruding from the wooden body 3 and the housing 6 integrally fitted with the brush body 2 are squeezed, so that the brush body 2 is left. Right-hand brushing causes slid by friction with teeth and skin in the mouth.

The friction protrusion 5 of the present invention provides a locking means for pushing and pulling the brush body in contact with the brush body back and the mouth skin. Therefore, the brush body rotates more smoothly, and the cleaning efficiency of the teeth, which is the object of the present invention, is improved.

Claims (1)

A rotating toothbrush in which a circular brush body (2) is rotatable from a wooden body (3), wherein a plurality of friction protrusions (5) are formed on the back of the brush body (2).
