Abstract

The utility model relates to a toothbrush enabling a brush head 7 to carry out reciprocating motion on the upper end of a brush neck 11. A handle 12 is held, a switch 16 is turned on, a power 15 is switched on, a motor 17 and an output shaft 18 can be directly connected with a cylindrical cam 19 to enable the cylindrical cam 19 to rotate, and the cylindrical cam 19 rolls with a rolling wheel 3 and drives a push rod 1 to enable the brush head 7 which is tightly connected with the push rod 1 to move up and down under the action of a pressing spring 5 simultaneously; when brush bristles are attached to teeth and particularly attached to the commutative rugged curved parts of teeth and gingivae, the brush bristles can carry out the reciprocating motion along the parts to clean dirt out of the parts; the brush bristles carry out reciprocating motion within a short range on the teeth in a transversal direction and clean over the tooth surfaces repetitiously in a large area; when the power applied on the tooth surfaces by the brush bristles is overlarge, the reciprocating motion of the brush bristles can be stopped; so the teeth and the gingivae can be protected from damaging.

Description

Follower lever promotes the reciprocating toothbrush of brush

The armature that the end face that this utility model relates to a kind of motor-driven cylindrical cam or disc cam holds out against follower lever or alternating electromagnet connects follower lever, makes the reciprocating toothbrush of brush, belongs to field of electric toothbrushes.

Cup type brush about the diameter 10mm that Germany Bo Lang produces, electric toothbrush with 7600 times/minute left-right rotation, be difficult to when brushing teeth with cup-shaped brush put into exactly with the equal tooth in rim of a cup footpath on, during the brush rotation to gingiva oppositely brush do not meet perpendicular brush method along interdental brush.

This novel shortcoming that overcomes above-mentioned electric toothbrush makes brush (identical with the head shapes of ordinary toothbrush) straight line swing in short distance (0-5mm), when the vertical tooth brushing tooth, bristle is through unlimited paddling on facing, particularly: bristle is along tooth and the curvilinear motion of gingiva junction, remove the dirt at its curve place, make repeatedly the paddling bristle cover the facing of being brushed, improve the brushing efficiency several times.

The technical scheme that the technical problem of this novel solution adopts is: in the brush shin reciprocating follower lever is housed, output shaft by motor-driven mechanism, drive the rotation of eccentric or cam, withstand the lower end of push rod, and under the effect of stage clip, the brush on the push rod is moved back and forth in (0-5mm).When bristle is done small linear reciprocating motion on facing, cooperate perpendicular brush method the dirt of tooth and gingiva junction and ditch nest can be cleaned out.

Below in conjunction with drawings and Examples this utility model is further specified.

Fig. 1, Fig. 2, Fig. 3, Fig. 4 are respectively cylindrical cams, three limit disc cams, hexagon disc cam, tractive magnet drive the follower lever mechanical schematic diagram of a half period of motion.Fig. 5 is Fig. 1, Fig. 2, and Fig. 3, Fig. 4 cam or solenoid actuated follower lever arrive low from low to high ... do the theory curve of linear reciprocating motion.Fig. 6 is: the vertical section structural map of this novel first embodiment.Fig. 7-Figure 13 is respectively AA, BB, CC, DD, EE, FF, the GG cutaway view of Fig. 6.Figure 14, Figure 15 is respectively: the longitudinal section of this novel the second, the three embodiment.Figure 16-Figure 21 is respectively Figure 13, the AA of Figure 14, BB, CC, DD, EE, FF cutaway view.Figure 22 is the longitudinal section of this novel the 4th embodiment.At Fig. 1, Fig. 2, Fig. 3 is respectively cylindrical cam 19 among Fig. 4, disc cam 6, tractive magnet (armature movable core) (20) drive follower lever 1 under the elastic force effect of compression spring 5, make follower lever from low → high → low ... move back and forth.Fig. 5 is a follower lever by low (H) → high (H) → low ... back and forth do the theoretical diagram (only representing 1 half period among the figure) of periodic movement.

Follower lever 1 lower end connects the spin 21 of support 4 in Fig. 6, as Figure 11, shown in the FF, spin 21 is by rotating shaft 22 back-up roller shaft supporting frames 23, spin 21 is rolled (being applicable to cylindrical cam mechanism) or roller 3 and directly be that slick sphere termination is directly made in the termination of follower lever with support 4 to all directions in that bracing frame is cofree, above follower lever 1, be inserted in the boss 24 of compression spring 5 to support 4, upper end with follower lever 1, penetrate brush shin 11 cavitys from handle 12 lower end cavitys, to be contained in motor 17 again and directly be connected cylindrical cam 19 with output shaft 18, (translating cam is wound into cylindrical cam), cylindrical end face withstands spin 21, the elastic force of stage clip 5 is adjusted in selection, stage clip 5 upper ends are withstood on brush shin 11, concave station 25 places, with screw 26 masterpiece of motor shaft 18 follower levers 1 is used for axle 18, so on the rotor termination, be equipped with and push away (pressure) mechanical axis and hold 27, follower lever 1 is exposed to brush shin 11 junctions, with gum elastic 2 sealings, when follower lever 1 in brush shin 11 during play, gum elastic 2 is also done elastic expansion thereupon, flexible, in case dirt enters in the follower lever 1 smooth inner chamber brush shin 11, for reducing follower lever 1 in brush shin inner chamber internal friction power, at they glade plane space place adding lubricating oil, when cylindrical cam 19 rotations, cylindrical end holds out against spin 21 under the effect of stage clip 5, support roller bearing 23 cofree rotations at rotating shaft 22, for preventing that follower lever 1 from producing rotation when brush shin 11 cavitys are done linear reciprocating motion, non-cylindrical is made in the follower lever cross section, as Fig. 7-Fig. 9 cutaway view.Drive the reciprocal play of bristle head being connected by gum elastic 9 when making follower lever 1 play at the brush shin 8 of bristle head 7 with brush shin oversheath 10.When follower lever 1 play drives brush 7 plaies, gum elastic 2 and gum elastic 9 be also with doing stretching motion, when need changing brush head 7, pulls up again and plug (shown in Fig. 6 left side) and get final product.Handle 12 is opened switch 16, and energized 15 " motor " rotation makes " cam " drive follower lever 1 and drives brush 7 back and forth first motion at a high speed.

At Figure 14, shown in Figure 15 second, among the 3rd embodiment, (motor output shaft connects two conical gears when motor-driven mechanism, bent tooth conical gear, helical gear, worm and wormwheel or the like, or directly by the direct driving shaft 14 of motor driver) 13, drive the cam 6 that is connected one with output shaft 14, disc cam is 3,4,5,6 ... every limit of N polygon is that convex is slick, makes cam 6 and ball wheel 3 rotate the power of reducing friction mutually, follower lever traction directly is connected, when armature is done linear reciprocating motion follower lever 1 play (on brushing in the shin thereupon with follower lever 1 by the armature slide core 28 of electric magnet 20, following play).
