The utility model adopts the following technical scheme:
the utility model provides an electric toothbrush with reciprocating rotation brush head, include the handle, set up in positive reverse motor in the handle, with handle swing joint's brush-holder stud and with brush-holder stud swing joint's brush head, be equipped with deflection mechanism and slewing mechanism in the brush-holder stud, the pivot of positive reverse motor is connected deflection mechanism's one end, deflection mechanism's the other end is connected slewing mechanism's one end, slewing mechanism's the other end is connected brush head, positive reverse motor drives deflection mechanism rotation mechanism with brush head reciprocating rotation.
Preferably, the deflection mechanism comprises an eccentric wheel, an eccentric column is arranged on the eccentric wheel, and the eccentric column is connected with one end of the rotating mechanism.
Preferably, the rotating mechanism comprises a rotating seat and a rotating rod, one end of the rotating rod is fixedly connected with the rotating seat, and the eccentric column is inserted into the rotating seat.
Preferably, a groove is formed in the bottom of the rotating seat, the eccentric column is inserted into the groove, and the other end of the rotating rod is movably connected with the brush head; wherein, the eccentric column drives the rotating seat, the rotating rod and the brush head to rotate in a reciprocating manner.
Preferably, a cavity is arranged in the brush rod, the rotating mechanism is arranged in the cavity and opposite to the cavity, and the brush rod rotates in a reciprocating manner.
The beneficial effects of the utility model reside in that: the utility model provides an electric toothbrush connects the dwang through setting up the eccentric wheel, drives the brush head and controls the rotation, and the manual mode of brushing teeth of simulation protects tooth surface and gum, because the motor is quick just reversing, improves the brush hair and comes the frequency of back-brushing to the tooth surface simultaneously, improves the tooth cleanliness yet, can not harm the gum.

Detailed Description
The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed embodiments and the specific operation processes are provided, but the protection scope of the present invention is not limited to the present embodiment.
In this embodiment, as shown in fig. 1 to 6, an electric toothbrush with a reciprocating rotating brush head comprises a handle 1, a forward and reverse rotating motor 2 arranged in the handle 1, a brush rod 3 movably connected with the handle 1, and a brush head 4 movably connected with the brush rod 3, wherein a deflection mechanism 5 and a rotating mechanism 6 are arranged in the brush rod 3, a rotating shaft of the forward and reverse rotating motor 2 is connected with one end of the deflection mechanism 5, the other end of the deflection mechanism 5 is connected with one end of the rotating mechanism 6, the other end of the rotating mechanism 6 is connected with the brush head 4, and the forward and reverse rotating motor 2 drives the deflection mechanism 5, the rotating mechanism 6 and the brush head 4 to rotate in a reciprocating manner.
Furthermore, the deflecting mechanism 5 comprises an eccentric wheel 51, an eccentric column 52 is arranged on the eccentric wheel 51, and the eccentric column 52 is connected with one end of the rotating mechanism 6.
Furthermore, the rotating mechanism 6 includes a rotating seat 61 and a rotating rod 62, one end of the rotating rod 62 is fixedly connected with the rotating seat 61, and the eccentric column 52 is inserted into the rotating seat 61.
Furthermore, a groove 63 is formed at the bottom of the rotating seat 61, the eccentric column 52 is inserted into the groove 63, and the other end of the rotating rod 62 is movably connected with the brush head 4; wherein, the eccentric column 52 drives the rotating seat 61, the rotating rod 62 and the brush head 4 to rotate in a reciprocating manner.
It should be noted that the eccentric column is far away from the center of a circle of the eccentric wheel, is clamped with the long groove, generates a rotating force when the forward and reverse rotation motor rotates forward and reverse, and drives the rotating rod connected with the eccentric wheel to rotate in a reciprocating manner.
In this embodiment, a cavity is formed in the brush rod 3, the rotating mechanism 5 is disposed in the cavity, and the brush rod 3 rotates reciprocally relative to the cavity.
It should be noted that the rotating mechanism is accommodated in the brush rod, when the eccentric wheel and the rotating rod rotate, the brush rod is kept still, the eccentric wheel and the rotating rod rotate in a reciprocating manner relative to the eccentric wheel and the rotating rod, and the top end of the brush rod can be provided with a hole for the brush head connected with the rotating rod to extend out.
It should be noted that the inside connecting key that matches with the joint groove that is equipped with in brush-holder stud bottom can make the brush-holder stud connect on the brush holder through joint groove and connecting key looks joint, the brush head is removable setting, and the change can be dismantled from the dwang to the brush head.
The electric toothbrush with the reciprocating rotating brush head has the working principle that:
for positive and negative motor access power, positive and negative rotation of motor drives the synchronous positive and negative rotation of eccentric wheel, the eccentric wheel pass through eccentric post with the dwang is connected and is driven dwang reciprocating rotation, and the brush head also reciprocating rotation simultaneously of being connected with the dwang, user grip handle with the brush-holder stud transversely and stretch into the oral cavity, the tooth surface is pressed close to the brush head, the relative tooth of brush head is rotated from top to bottom, cleans the tooth.
The electric toothbrush in this embodiment drives the brush head and rotates about through setting up the eccentric wheel and connecting the dwang, simulates the mode of manual brushing teeth, also can protect the tooth surface when cleaning the tooth, simultaneously because the motor is positive and negative to rotate fast, improves the brush hair and comes the frequency of back-brushing to the tooth surface, improves the tooth cleanliness, also can not harm the gum.
Various corresponding changes and modifications can be made by those skilled in the art according to the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
