  • Patent number: 12144415
    Abstract: A toothbrush includes an anisotropic deformation portion (70) on a rear end side from the bristle tufting surface (11), and a bending strength in a first direction orthogonal to the bristle tufting surface that is smaller than a bending strength in a second direction orthogonal to the long axis direction and the first direction. The anisotropic deformation portion includes an elastic deformation portion (90) that connects a first region on the tip end side from the anisotropic deformation portion and a second region on the rear end side from the anisotropic deformation portion. The elastic deformation portion is elastically deformable in the first direction and the second direction, and bending load when the head portion is displaced in the first direction is lower than a bending load when the head portion is displaced in the second direction.

  • Patent number: 12137798
    Abstract: A toothbrush includes a head portion (10) having a bristle tufting surface; a grip portion (30) disposed on a rear end side from the head portion; a neck portion (20) disposed between the bristle tufting surface (11) and the grip portion; and a sensing portion (70) for sensing that an external force in a first direction orthogonal to the bristle tufting surface exceeds a threshold value. A reversal portion (80) connects a first region and a second region, and snaps, buckles, and reverses as the head portion is displaced on a rear surface side due to the external force exceeding the threshold value. An elastic deformation portion (90) connects the first region and the second region, and elastically deforms at least up to the external force at which the reversal portion snaps, buckles, and reverses.

  • Publication number: 20220015531
    Abstract: A toothbrush enables an appropriate brushing pressure and includes a sensing portion for sensing that an external force in a first direction orthogonal to the bristle tufting surface exceeds a predetermined value on a rear end side from the bristle tufting surface. The sensing portion changes a relationship between a displacement amount of the head portion when a load is applied to the head portion and a repulsive force generated according to the displacement amount from an increase to a decrease in the repulsive force at a first threshold value. The first threshold value relates to an increase in the displacement amount, and stops the decrease in the repulsive force at a second threshold value. The second threshold value relates to when the displacement amount is larger than the first threshold value.
