Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-7, the present invention discloses a brush head with left and right rotation function, which comprises a brush head 1, wherein the brush head 1 is provided with a brush 11, a rotor 14 for driving the brush 11, and an eccentric rod 17 eccentrically arranged on the rotor 14 for pulling the rotor 14 to rotate.

Specifically, preforming 13 is movably sleeved on the surface of rotor 14, the number of protrusions clamped with the inner portion of brush head 1 is not less than one on preforming 13, so that rotor 14 is limited in the brush head 1, one side of rotor 14 is provided with pull plate 15, and two ends of pull plate 15 extend to one side of preforming 13, referring to fig. 4, preforming 13 enables self-clamping in the inner portion of brush head 1 to be incapable of rotating through the protrusions, and two ends of pull plate 15 contact with one side of preforming 13, so that rotor 14 is limited by preforming 13 and only can rotate in the inner portion of brush head 1, and stability of rotor 14 is guaranteed.

Specifically, the inside of arm-tie 15 is seted up the eccentric orfice 16 that a quantity is no less than one, the one end of eccentric pole 17 is cup jointed with the inside activity of one of them eccentric orfice 16, the fixed pull rod 12 that is provided with of one end that eccentric orfice 16 was kept away from to eccentric pole 17, the one end that eccentric pole 17 was kept away from to pull rod 12 is used for connecting reciprocating type actuating mechanism, refer to fig. 7, after brush head 1 is connected with the electric toothbrush main part, reciprocating type actuating mechanism pulling pull rod 12 in the electric toothbrush main part carries out up-and-down reciprocating motion, pull rod 12 pulling eccentric pole 17, eccentric pole 17 drives rotor 14 through eccentric orfice 16 and carries out reciprocating rotation, thereby make rotor 14 drive brush 11 rotate and clear up the tooth, reciprocating type eccentric mechanism adopts conventional motor, gear and eccentric transfer line to constitute, the motor drives the gear and rotates, eccentric transfer line eccentric transfer to setting on the gear, drive eccentric transfer line pulling pull rod 12 when making the gear rotate and carry out reciprocating motion.
