Description

a toothbrush

technical field

The utility model relates to the technical field of daily necessities, in particular to a toothbrush.

Background technique

The current toothbrush includes a brush rod and bristles. When people brush their teeth, the part of the brush rod is exposed outside the oral cavity, and there is no shield between the oral cavity and the hand holding the toothbrush. When the toothbrush is used, the foam generated in the mouth will flow and drip along the rod. To the arm that holds the toothbrush, the arm and sleeve are dirty, and the foam that the bristles pop up from the mouth will splash directly on the arm, and it will also stain the arm and sleeve.
