Timed quantified circular toothbrush for child

Abstract

The invention relates to a timed quantified circular toothbrush for a child. An inner rod is arranged in an outer rod, a switch is fixed to the bottom end of the inner rod, a battery, a timer and a buzzer are arranged at the bottom of the inner rod, toothpaste is arranged at the upper part of the outer rod, the top of the outer rod is connected with a toothbrush head, a motor is arranged in the toothbrush head, an inner circular brush is fixed to the top end of a shaft of the motor, a gear reducer is mounted on the shaft of the motor and is connected with a toothbrush disc, and an outer circular brush is arranged on the toothbrush disc. According to the timed quantified circular toothbrush for the child, the toothpaste in the outer rod is extruded into the brush head part through spiral rising of the inner rod, the toothpaste is extruded out from a discharging opening of the brush head, the toothpaste can be quantitatively extruded through one or half circle of spiral turning, and theinternal wall of the outer rod has spiral threads which correspond to those of the surface of the inner rod. The toothbrush head is divided into two parts, i.e., the outer circular brush and the innercircular brush, the inner circular brush is directly driven by the motor, and the outer circular brush is subjected to speed reduction by the speed reducer and then is driven, so that the toothbrushhead can adapt to different positions needing cleaning in oral cavities, the interestingness is improved, the interest of tooth brushing of the child is improved, and teeth can be better protected.

Description

technical field [0001] The present invention relates to a toothbrush for children, in particular to a round toothbrush for children whose toothpaste can be precisely dosed by rotating and propelling the inner rod, and a rotating fast inner circle brush and a slow speed outer circle brush are installed on the toothbrush head. . Background technique [0002] Today's children are just beginning to learn to brush their teeth. When they squeeze toothpaste, they either have a lot or very little, and they can't master the brushing time well. Although there are children's electric toothbrushes, they are the same as adult electric toothbrushes. Function, so it is very unfavorable to the protection of children's teeth. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a toothpaste that can be accurately quantified by rotating the inner rod, and a timing quantitative circle with a rotating fast inner ...
