Abstract

The invention relates to a brush head-replaceable electric toothbrush which comprises a brush handle and a brush head, wherein a pair of meshed driving gear and driven gear are mounted at the head part of the brush handle; a motor for driving the brush head to rotate and a power module electrically connected with the motor are also mounted in the brush handle; an output shaft of the motor is connected with a worm meshed with the driving gear; and a rotation shaft of the driving gear is in movable detachable connection with the lower end part of the brush head, and a rotation shaft of the driven gear is in movable detachable connection with the upper end part of the brush head, so that the upper end part and the lower end part of the brush head rotate in opposite directions respectively. In the brush head-replaceable electric toothbrush provided by the invention, the rotation shafts of two gears are driven to rotate by the motor and the worm so as to drive the brush head to rotate, wherein the rotation is relatively slow, and the gum is not hurt; moreover, the bristles on the brush head are clean and have large cleaning area and high efficiency; and meanwhile, the brush head can be regularly replaced, thus the cost of repurchasing the whole electric toothbrush is saved.

Description

A kind of electric toothbrush of replaceable brush

Technical field

The present invention relates to a kind of electric toothbrush of replaceable brush.

Background technology

Electric toothbrush more can thoroughly remove dental plaque, reduce gingivitis and gingival hemorrhage compared to ordinary toothbrush; It passes through fast rotational; Make bristle produce dither, moment is resolved into trickle foam with toothpaste, deeply cleans teeth space; The vibration of bristle simultaneously can promote the blood circulation in oral cavity, and gingiva tissue is had beyond thought massage effect.But electric toothbrush in the market is the medium position of brush can rotatablely move; Rotating mechanism generally adopts two bevel gears that are meshed of motor direct-drive, because rotary speed is too fast, therefore is easy to damage gingiva; And the cleaning area is less, and cleaning efficiency is too low.

Summary of the invention

In view of the deficiency of prior art, the object of the present invention is to provide and a kind ofly can not damage gingiva, the cleaning area is big and the electric toothbrush of the replaceable brush that efficient is high.

To achieve these goals; Technical scheme of the present invention is: a kind of electric toothbrush of replaceable brush; Comprise brush holder and brush; The head of said brush holder is equipped with a pair of driving gear that is meshed and driven gear, and the power module that is used to drive the brush motor rotating and electrically connects with motor also is installed in the said brush holder, and the output shaft of said motor is connected with the worm screw that is meshed with driving gear; The bottom activity releasable connection of the rotating shaft of said driving gear and brush, the upper end activity releasable connection of the rotating shaft of said driven gear and brush makes the upper end of brush and bottom do in the opposite direction rotatablely moving respectively.

Further, offer first through hole that matches with a rotating shaft and second through hole that matches with another rotating shaft on the said brush.

Further, said rotating shaft is Z-shaped axle, and an end of said rotating shaft is positioned at the locating slot on the brush holder, and the other end of said rotating shaft is provided with and is used to block brush so that the protruding medicated cap of changing brush head more.

Further, said motor is a direct current generator, and said power module is aneroid battery, lithium battery or accumulator.

Further, said brush holder is provided with and is used to control the power control switch that motor opens and closes.

Compared with prior art; The present invention has the following advantages: the electric toothbrush of this replaceable brush is done in the opposite direction rotatablely moving respectively through upper end and bottom that motor and worm screw drive two rotary gear shaft rotations and then drive brush; Not only the worm and wormwheel deceleration transmission greatly reduces the rotary speed of brush; Can not hurt gingiva; And the cleaning of the bristle on brush area is big, clean and efficient is high, can also regularly replace brush simultaneously, has saved the expense of purchasing whole electric toothbrush again.

Below in conjunction with accompanying drawing and embodiment the present invention is done further elaboration.

Among the figure: 1-brush holder, 1-1-locating slot, 2-brush, 3-driving gear, 4-driven gear, 5-motor, 5-1-output shaft, 6-power module, 7-worm screw, 8-rotating shaft, the protruding medicated cap of 8-1-, 9-first through hole, 10-second through hole, 11-power control switch.

The specific embodiment

With reference to figure 1 ~ 4; A kind of electric toothbrush of replaceable brush; Comprise brush holder 1 and brush 2; The head of said brush holder 1 is equipped with a pair of driving gear that is meshed 3 and driven gear 4, also is equipped with in the said brush holder 1 to be used to the power module 6 that drives brush 2 motor rotating 5 and electrically connect with motor 5, and the output shaft 5-1 of said motor 5 is connected with the worm screw 7 that is meshed with driving gear 3; The rotating shaft 8 of said driving gear 3 and the bottom activity releasable connection of brush 2, the rotating shaft 8 of said driven gear 4 and the upper end activity releasable connection of brush 2 make the upper end of brush 2 and bottom do in the opposite direction rotatablely moving respectively.

In the present embodiment; Said rotating shaft 8 is Z-shaped axle; Offer first through hole 9 that matches with a rotating shaft 8 and second through hole 10 that matches with another rotating shaft 8 on the said brush 2; One end of said rotating shaft 8 is positioned at the locating slot 1-1 on the brush holder 1, and the other end of said rotating shaft 8 is provided with and is used to block brush 2 so that the protruding medicated cap 8-1 of changing brush head 2 more.When brush 2 was installed, first through hole 9 was passed in two rotating shafts 8 respectively, brush 2, easy accessibility are blocked by protruding medicated cap 8-1 in second through hole, 10 backs.

In the present embodiment, said motor 5 is a direct current generator, and said power module 6 is aneroid battery, lithium battery or accumulator etc., user's replaceable battery or charge; Said brush holder 1 is provided with and is used to control the power control switch 11 that motor 5 opens and closes, and said power control switch 11 can be arranged at the bottom of brush holder 1, can avoid the user to be not intended in use run into power control switch 11, but be not limited to this.

Work process of the present invention is following: motor 5 drives worm screw 7 and rotates; Worm screw 7 drives driving gear 3 and rotates; Driving gear 3 drives driven gear 4 and does backward rotation, and driving gear 3 drives rotating shaft 8 rotations separately with driven gear 4, and the bottom that the rotating shaft 8 of driving gear 3 drives brush 2 is done and is rotated counterclockwise; The upper end that the rotating shaft 8 of driven gear 4 simultaneously drives brush 2 is done and is turned clockwise, and then the bristle on the realization brush 2 is cleared up tooth.

Need to prove especially, can certainly be that dextrorotation is done in the bottom of brush 2 then the upper end is done and is rotated counterclockwise.Brush realizes clockwise and rotation synchronously counterclockwise simultaneously, cleaning teeth better, and cleaning effect is better.

The above is merely preferred embodiment of the present invention, and all equalizations of doing according to claim of the present invention change and modify, and all should belong to covering scope of the present invention.
