Abstract

An electric tooth-brush is composed of handle, brush bar and brush head, and features that its drive mechanism in handle is adjustable and it has a trace controller which can make brush head do different movements such as longitudinal or transverse linear reprocating one, planar circumferential one, or planar elliptical ones for higher cleaning effect.

Description

Electric toothbrush

The present invention relates to a kind of toothbrush, particularly a kind of by power-actuated toothbrush.

Existing electric toothbrush, the movement locus of its brush is made molding once brushing tool and promptly is fixed, can't in use change, as the vertical straight reciprocating motion of simple brush, the horizontal straight reciprocating motion of brush, planar circumferential motion or plane elliptic motion.Chinese patent application CN90100097 " electric toothbrush ", the flat 6-245819 of Japanese patent application TOHKEMY " electric toothbrush " disclose the patent application that a kind of brush rotates respectively, Chinese patent application CN92107095 " electric toothbrush " discloses the patent application of the vertical straight reciprocating motion of a kind of brush, but their movement locus in use can't change.The single movement locus of these electric toothbrushes has limited the effect of brushing teeth, can't utilize the toothbrushing effect complementation of various movement locus, moreover user is because the difference of oral conditions or have a preference for certain movement locus of brushing teeth, and above-mentioned electric toothbrush can't provide multiple choices.

The object of the present invention is to provide a kind of electric toothbrush, the movement locus of brush can be controlled, and can make multiple forms of motion, makes the toothbrushing effect of various movement locus obtain complementation.

The object of the present invention is achieved like this: electric toothbrush 1. of the present invention is made up of handle, brush holder, brush, and handle is a tubular shell, and interior device has battery, motor, reducing gear, brush holder driving mechanism, TRAJECTORY CONTROL mechanism and electric switch.2. brush holder driving mechanism and TRAJECTORY CONTROL mechanism lay respectively at the both sides of brush holder, and motor drives the brush holder driving mechanism by reducing gear.3. the change of the formation of brush holder driving mechanism and drive form is realized by following steps, rotate synchronously by at least two of the driven in synchronism gear drive parallel eccentric component of being separated by, this member can be a kind of in eccentric shaft, camshaft, the crank axle, the eccentric end of eccentric component is inserted respectively in the concave groove of combination chute one side that is hinged on the brush holder, hinged centre-to-centre spacing equals the centre-to-centre spacing of eccentric component, the sliding tray width of cloth of combination chute by its opposite side matches with TRAJECTORY CONTROL mechanism, and this sliding tray width of cloth can be a kind of in dovetail groove, emboss pit, the TC type groove.The combination chute both sides sliding tray direction vertical mutually, by bearing pin brush holder is placed between two grooves hinged, corresponding to the combination chute different angle positions, the forms of motion respective change of brush holder.When the axis of the concave groove that inserts eccentric end is vertical with the brush holder longitudinal axis, brush holder drive brush in the plane of vertical bristle work along brush holder linear reciprocating motion track longitudinally.When two axial lines was parallel, brush holder drove brush and does along the horizontal linear reciprocating motion track of brush holder in the plane of vertical bristle.When two axial lines became miter angle, brush holder drove brush and makes circular motion track in the plane of vertical bristle.When two axial lines became other angle, brush holder drove brush and makes multiple elliptical trajectory in the plane of vertical bristle.4. the formation of TRAJECTORY CONTROL mechanism and control are realized by following steps, the active synchronization control gear of selecting button is housed by an axle head, under spring action, be meshed with driven Synchronization Control gear and the lock gear that is fixed on the housing simultaneously, be provided with and make up the sliding tray pair that chute is complementary at Synchronization Control gear shaft terminal with the eccentric component coaxial line.Move axially the selection button, active synchronization control gear and lock gear break away from, and rotate and select button, the Synchronization Control gear rotates by the moving combination of axle head sliding tray subband chute, decontrols and selects button, under the effect of spring force, the Synchronization Control gear is meshed with lock gear, and selected corner is locked.5. be provided with the ripple sealing shroud in the exit that brush holder stretches out handle, make by fluid-tight flexibility or elastomeric material.Brush and brush holder adopt and flexibly connect.Be provided with reducing gear between motor and the brush holder driving mechanism, this reducing gear can be made of one-level conical gear and secondary column gear transmission or one-level conical gear and primary cylinder gear drive mechanism, also can be made of three grades or secondary column gear transmission mechanism.Electric switch just has to be changeed, reverse, stop three kinds of states, is used to control turning to and stopping of motor.

The invention has the beneficial effects as follows: owing to adopted adjustable brush holder driving mechanism and TRAJECTORY CONTROL mechanism, can make brush produce vertical, horizontal straight reciprocating motion track, planar circumferential movement locus and multiple plane elliptical trajectory, and can select arbitrarily at any time, can make the effect of the multiple movement locus of brushing teeth obtain complementation like this, make the better effects if of brushing teeth, simultaneously also for wanting that the user of attempting some brush teeth movement locus and certain movement locus of brushing teeth of preference provides multiple choices.

synchronism gear

16,15,14 and rotate synchronously, the eccentric end of eccentric shaft is inserted respectively in the concave groove 19,20 of combination chute one side that is hinged on the brush holder 2.Concave groove 19, with dovetail groove 34, bearing pin 36, concave groove 20, with dovetail groove 26, bearing pin 28 is formed two combination chutes respectively, hinged centre-to-centre spacing equals the centre-to-centre spacing of eccentric shaft, the combination chute matches with TRAJECTORY CONTROL mechanism 10 by the sliding tray width of cloth, the sliding tray width of cloth is respectively by

dovetail groove

34,35 and 26,27 form, the both sides sliding tray direction of combination chute is vertical mutually, by bearing

36,28 place two combination chutes concave grooves 19 separately with brush holder 2, dovetail groove 34 and concave groove 20, hinged between the dovetail groove 26, corresponding to the different angle positions of combination chute, the forms of motion respective change of brush holder 2.When the axis of the concave groove 19 that inserts eccentric end is vertical with brush holder 2 longitudinal axis, brush holder 2 drive brushes 1 in the plane of vertical bristle 8 work along brush holder 2 linear reciprocating motion track longitudinally.When two axial lines was parallel, brush holder 2 drove brush 1 and does along brush holder 2 horizontal linear reciprocating motion tracks in the plane of vertical bristle 8.When two axial lines became miter angle, brush holder 2 drove the planar circumferential movement locus that brush 1 is made vertical bristle 8.When two axial lines became other angle, brush holder 2 drove brushes 1 and makes multiple elliptical trajectory in the plane of vertical bristle 8.4. the formation of TRAJECTORY CONTROL mechanism 10 and control are realized by following steps, promote to select button 11 to press spring 32, the lock gear that is fixed on the housing 13 31 and the internal tooth of active synchronization control gear 30 are separated, rotate and select button 11, active synchronization control gear 30 drives driven Synchronization Control gear 29,33 and
