Abstract

The utility model particularly relates to an electric toothbrush, which comprises a brush head and a brush handle. An power supply circuit composed of a motor, a battery and a switch is arranged in the brush handle; a first transmission tooth is connected with the tail end of a transmission shaft of the motor, and kneaded with a transmission tooth disk; a bent shaft is connected with the transmission tooth disk and a thin sheet arranged on the upper surface of the brush head; brush hair is mounted on the thin sheet and driven by the bent shaft to move upwards and downwards; a second transmission tooth is also kneaded with the transmission tooth disk, and connected with another bent shaft; the bent shaft is connected with another thin sheet arranged on the upper surface of the brush head; and brush hair is mounted on the thin sheet and driven by the bent shaft to move leftwards and rightwards. After the utility model adopts the technical proposal, two parts of brush hair on the brush head respectively carry out different movement manners; the brush hair moving upwards and downwards can clean the surfaces of the teeth while the brush hair moving leftwards and rightwards can clean teeth grooves, so that the movement has not only high cleaning efficiency, but also small abrasion to the teeth.

Description

A kind of electric toothbrush

Technical field

This utility model relates to the daily living article technical field, refers in particular to a kind of cleaning efficiency height, the electric toothbrush little to tooth wear.

Background technology

Existing electric toothbrush mostly is single rotary-type, and its shortcoming is: the first, and single rotation mode does not meet the action of brushing teeth, and is difficult to comprehensive cleaning oral cavity; The 2nd, after the normal phase practicality of this motion mode, can cause very big wearing and tearing to tooth.

Summary of the invention

The purpose of this utility model provides a kind of cleaning efficiency height, the electric toothbrush little to tooth wear.

For achieving the above object, the technical scheme that this utility model provides is: include brush and brush holder, be provided with the power circuit of motor, battery, switch formation in the brush holder, the end of motor transmission shaft is connected with first driving cog, this first driving cog and a transmission fluted disc are mediated, and the transmission fluted disc is connected with a bent axle, and this bent axle is connected with the thin slice of being located at the brush upper surface, on this thin slice bristle is housed, the bristle that this bent axle drives on the thin slice moves up and down; The transmission fluted disc has also been mediated one second driving cog, and this second driving cog is connected with another bent axle, and this bent axle is connected with another thin slice of being located at the brush upper surface, on this thin slice bristle is housed, and this bent axle drives the bristle side-to-side movement on this thin slice.

After this utility model adopts technique scheme, two parts bristle on the brush is done different motion modes respectively, but that part of bristle teeth surfaces that moves up and down, that part of bristle of side-to-side movement can clean alveolus, such motion is the cleaning efficiency height not only, and little to the wearing and tearing of tooth.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, present embodiment includes brush 1 and brush holder 2, be provided with the power circuit of motor 3, battery 4, switch 5 formations in the brush holder 2, the end of motor transmission shaft is connected with first driving cog 6, this first driving cog 6 and a transmission fluted disc 7 are mediated, and transmission fluted disc 7 is connected with a bent axle 8, and this bent axle 8 is connected with the thin slice 9 of being located at the brush upper surface, on this thin slice 9 bristle 10 is housed, the bristle 10 that this bent axle 8 drives on the thin slice 9 moves up and down; Transmission fluted disc 7 is also mediated one second driving cog 11, this second driving cog 11 is connected with another bent axle 12, this bent axle 12 is connected with another thin slice 13 of being located at the brush upper surface, on this thin slice 13 bristle 14 is housed, and the bristle 14 that this bent axle 12 drives on this thin slice 13 is done side-to-side movement.During work, first driving cog 6 is by motor 3 driven rotary, transmission fluted disc 7 rotates under the drive of first driving cog 6 again, second driving cog 11 rotates under the drive of transmission fluted disc 7 again, and the transmission fluted disc 7 and second driving cog 6 drive bent axle 8,12 motion separately respectively, thus by bent axle 8,12 control that part of bristle on the thin slice 9,13 separately do respectively about, the side-to-side movement action of brushing teeth.

Claims (1)

1, a kind of electric toothbrush, include brush and brush holder, be provided with the power circuit of motor, battery, switch formation in the brush holder, it is characterized in that: the end of motor transmission shaft is connected with first driving cog, this first driving cog and a transmission fluted disc are mediated, and the transmission fluted disc is connected with a bent axle, and this bent axle is connected with the thin slice of being located at the brush upper surface, on this thin slice bristle is housed, the bristle that this bent axle drives on the thin slice moves up and down; The transmission fluted disc has also been mediated one second driving cog, and this second driving cog is connected with another bent axle, and this bent axle is connected with another thin slice of being located at the brush upper surface, on this thin slice bristle is housed, and this bent axle drives the bristle side-to-side movement on this thin slice.
