DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described. FIG. 1 is an exploded view of each part of a toothbrush with an interdental brush according to the present invention. FIG. 2 is a rear view in which the respective parts according to FIG. 1 are united for portable use. FIGS. 3, 4, 5, and 6 are implementation views at the time of use according to FIGS. FIG. 7 is an enlarged perspective view showing the state of separation and combination of the interdental brushes related to the interdental brush storage section 4. FIG. It is an end view. A cut is made in a U-shape from the tip of the grip portion of the toothbrush body 1 in the separation view shown in FIG. 1 to form the interdental brush storage section 4 and the interdental brush body 2 to the rotating shaft 6.
・ The 6 ′ and the bearings 5 ・ 5 ′ of the toothbrush body 1 are connected and stored. The fulcrum 7 of the grip portion of the toothbrush and the fulcrum support 8 of the interdental brush storage cover 3 are connected to each other to form the interdental brush cover 3.
When covered, the embodiment at the time of storage is shown in FIG. 3, which is a portable form at the time of uniting. FIG. 4 shows that, when used, the interdental brush housing cover 3 is opened, and the interdental brush main body 2 is rotated by 180 degrees about the rotation axis 6, 6 'of the interdental brush main body 2 so that the brush portion of the interdental brush main body 2 is located at the tip of the toothbrush main body 1. It is taken out from the portion, the interdental brush housing cover 3 is closed, and the interdental brush main body 2 is fixed so as not to move before use. FIG. 5 shows that when the interdental brush main body 2 is made to be perpendicular to the toothbrush main body 1, the interdental brush housing cover 3 is fixed by rotating the rotating shafts 6, 6 'of the interdental brush main body 2 by 90 degrees around the fulcrum. . In FIG. 6, by opening the interdental brush housing cover 3, the angle of the interdental brush main body 2 can be freely changed and the interdental brush can be cleaned by changing the angle. FIG. 7 is an enlarged perspective view of the interdental brush housing 4. When the toothbrush main body 1 and the interdental brush main body 2 are separated and used separately, the bearings 5 and 5 'of the toothbrush main body 1 are expanded. The two rotating shafts 6 and 6 'are separated from the bearings 5.5 and 5' and separated. FIG. 8 is an enlarged perspective view showing a use situation at the time of the union shown in FIG. 7. Cover and fix the storage cover 3. When the brush portion of the interdental brush main body 2 is used, it is rotated 180 degrees from the rotation shaft 6.6 'of the interdental brush as a base point from the above-mentioned storage, and the interdental brush storage cover body 3 is used.

[0007]

According to the present invention, the toothbrush main body 1 and the interdental brush main body 2 conventionally carried separately can be carried together. (B) The toothbrush main body 1 and the interdental brush main body 2 can be carried and used separately while being separated from each other. (C) The toothbrush main body 1 or the interdental brush main body 2 can be freely replaced by a structure that can be freely separated and combined. (D) The interdental brush main body 2 is rotatable by the interdental brush rotating shafts 6 and 6 '. When the interdental brush storage cover 3 is opened, the angle can be freely set and the interdental brush can be used. E Since the interdental brush main body 2 is located at the tip of the toothbrush main body 1, it is possible to clean a deep portion of the mouth. (F) The interdental brush storage cover 3 is provided as a fixture for maintaining the hygiene of the grip portion and for fixing the interdental brush body 2.
