Toothbrush with brush head capable of rotating

Abstract

The invention relates to a toothbrush with a brush head capable of rotating, and belongs to the technical field of living goods. The toothbrush comprises a brush handle, the brush head installed on the bottom surface of the front end of the brush handle and bristles arranged on the bottom surface of the brush head. The toothbrush is characterized in that a through hole is formed in the front end of the brush handle from the top surface to the bottom surface, a pin shaft perpendicular to the top surface of the brush head is fixed to the top surface of the brush head, and the pin shaft penetrates through the through hole to achieve rotating connection of the brush head and the brush handle. The brush head of the toothbrush can rotate to be perpendicular to the brush head or located on the same line with the brush head, and a user can conveniently brush all teeth in the mouth cavity in the direction parallel with the slits between the teeth without opening the mouth largely in the tooth brushing process, so that bacteria and food residues in the mouth cavity are thoroughly cleared away, periodontitis, gingivitis and other tooth diseases are effectively prevented, and the teeth are better protected.
