Abstract

The utility model relates to an electric toothbrush. The utility model is provided with a bush head 13 which can be moved vertically, horizontally and inwards and outwards relative to a handle 10. The movements are generated by a rotating arm 14. The rotating arm is moved along the cycle track under the drive of a motor which is positioned at the center of longitudinal axis A. The rotating arm is mechanically connected with a relaxation support push rod 16 through a driving medium 20. the push rod 16 is limited to be moved inwards and outwards along a longitudinal axis B.

Description

Electric toothbrush

Technical field

This utility model relates to a kind of electric toothbrush.

Background technology

Electric toothbrush is widely used, and in use makes brush transverse movement or whirling vibration usually.Once the someone propose a kind of laterally and the brush that combines of translational motion, still, this device has brought the problem of complex mechanical construction very and quite high cost.

Brief summary of the invention

The purpose of this utility model is to overcome or alleviate this problem at least.

This utility model provides a kind of electric toothbrush, it has the elongate handle with a motor, one cover driving device is arranged in handle, pass motion to the end and connecting the elongated brush holder of this handle, with simultaneously to brush holder provide with respect to handle from left to right and motion from the inside to surface, the parts of forming driving device comprise: the turning arm of the motor of ining succession, and can be around the first central longitudinal axis rotation on the handle; The push rod of the brush holder of ining succession is placed along parallel with the first longitudinal axis second central longitudinal axis, and push rod connects loosely away from that end of brush holder, so as can to rotate and respectively side-to-side movement to move along described second; The elongated driving member of axle is along the longitudinal connecting the end of above-mentioned turning arm and above-mentioned push rod, when turning arm rotates to brush holder transmission rotation and axially-movable.

The second central longitudinal axis can depart from the first central longitudinal axis to be arranged so that driving device about brush holder transmits simultaneously, about and about motion.

Elongated driving member can have a joint at each end, and an end of turning arm and push rod has the groove that matches with joint separately.

Can in handle, center on the sealing member of push rod placement of flexible.

Brush holder is more suitable for adopting dismountable form with being connected of push rod.

Can there be the Flexible clamp that fuses with it brush holder inside so that brush holder is clipped on the push rod.One end of brush holder can have a formed matrix adapter of cavity and a convex adapter that fuses with push rod one end to match, and matrix adapter and convex adapter form the sucking fit connecting device, loosely brush holder is connected on the push rod.

The accompanying drawing summary

Below in conjunction with drawings and Examples the electric toothbrush in this utility model is described:

Fig. 1 is the profilograph of toothbrush;

Fig. 2 is the partial enlarged drawing of Fig. 1;

Fig. 3 is the flat sectional drawing of electric toothbrush;

Fig. 4 is the part sectioned view of another kind of electric toothbrush;

Fig. 5 is the part sectioned view of another electric toothbrush;

Fig. 6 is the partial enlarged drawing of another electric toothbrush.

Preferred embodiment is described

Referring to accompanying drawing, at Fig. 1, in 2 and 3, toothbrush has the elongate handle that has motor 11 10 of a hollow.An elongated brush holder 12 links to each other with elongate handle 10 ends.Driving device is arranged in the toothbrush, can make the brush 13 that is positioned at brush holder 12 ends do with respect to elongate handle 10 about, about and about motion.

This driving device comprises a turning arm 14, and it can rotate around the first longitudinal axis A that is fixed in motor 11 rotating shafts in the handle 10.In the turning arm fluted 15.Push rod 16 is limited in sliding along the second longitudinal axis B, the second longitudinal axis B but offset placement parallel with the first longitudinal axis A.Push rod 16 is also spacing rotationally by

steering spindle

17 and 18, with the rectangular plane of longitudinal axis B on move.One end and the groove 19 of push rod fuse.

Driving member 20 with respect to axle A and B longitudinal extension can be with the

joint

21 and 22 of its end, embed with joint matches separately groove 15 and 19 in.When turning arm 14 rotation, about driving member 20 makes that an end of push rod 16 is done with respect to elongate handle 10, about and the motion of front and back.The result is that these motions send brush 13 to.Between the inside of the outside of push rod and handle housing 10, a flexible seal head 23 is arranged, can prevent that the aqueous vapor of porch from entering in the handle housing 10.

It should be noted that driving device is made up of simple assemblies, generally form, in the manufacture process of toothbrush, can be connected at an easy rate and assemble by molded plastic material.Such driving device can make that toothbrush cost in the mill is relatively low, and have the advantage that brush 13 can move in three dimensions, thus strengthened toothbrush in use scrub function.Because do not have gear drive or mechanical collision, thus above-mentioned toothbrush when operation itself (if not talkative it's not true) can not produce sizable noise.

Brush holder 12 adopts dismountable connected mode with more being suitable for being connected of push rod 16.Fig. 4 and Fig. 5 show two kinds of types of attachment between brush holder 12 and the push rod 16.In Fig. 4, brush holder 12 is made of reverse clip 24, this clip be positioned at convex adapter 25 on push rod 16 ends around.When brush holder was firmly spurred, convex adapter 25 was separated from from clip 24.Like this, clip 24 and adapter 25 forms and embeds the bindiny mechanism that cooperates, with removably with on the brush holder passageway handle housing 10.In Fig. 5, brush holder and hook 26 fuse, and hook 26 flexibly is engaged in the groove 27 of push rod 16 1 ends.When needs were removed and/or replace brush holder 12, if very strong brushing the housing 10 from handle spurs brush holder, the shape of hook 26 can make it eject from groove 27.

In Fig. 6, show same mechanism.The difference of itself and above-mentioned toothbrush essence is that the first longitudinal axis A and the second longitudinal axis B are in line.The result is, in the use of toothbrush, can pass to simultaneously brush holder from left to right, motion from the inside to surface.

Claims

1. electric toothbrush, it has the elongate handle with a motor, one cover driving device is arranged in handle, pass motion to end and connecting the elongated brush holder of this handle, with give brush holder provide simultaneously with respect to handle from left to right and motion from the inside to surface, the parts of forming driving device comprise: the turning arm of the motor of ining succession, and can be around the first central longitudinal axis rotation on the handle; The push rod of the brush holder of ining succession is placed along the second central longitudinal axis parallel with first longitudinal axis, and push rod is loosening away from that end connection of brush holder, so that can do rotation and the motion from a side to opposite side around above-mentioned two longitudinal axiss respectively; The elongated driving member of axle is along the longitudinal connecting the end of above-mentioned turning arm and above-mentioned push rod, when turning arm rotates to brush holder transmission rotation and axially-movable.
