[0002] Electric toothbrushes are new products that have appeared in recent years. Surveys show that electric toothbrushes are more scientific and effective than ordinary toothbrushes. They can more thoroughly remove dental plaque, reduce gingivitis and gum bleeding, and are currently popular daily necessities in many European and American countries. Electric toothbrushes rotate rapidly to produce high-frequency vibrations on the brush head, instantly breaking down toothpaste into fine foam and deeply cleaning the gaps between teeth; at the same time, the vibration of the bristles can promote blood circulation in the oral cavity and have an unexpected massage effect on the gum tissue.

[0003] Currently, the brush head of an electric toothbrush is generally a fixed structure, which is usually fixed at the front end of the handle. A vibration device is provided inside the handle, and the vibration device generates vibration and transmits it to the brush head, so that the brush head vibrates to brush the teeth. Since the brush head of this structure can only vibrate and cannot move, the brush head can only brush the teeth in a single direction. If the teeth are to be brushed in all directions, the user needs to move the entire toothbrush back and forth, which is very time-consuming and labor-intensive.

[0046] The working principle of this embodiment is described in detail as follows:

[0047] During use, apply toothpaste on the brush head group 60, and insert the support frame 12 into the oral cavity so that the brush head group 60 abuts against the teeth. When this product is turned on, the battery 70 supplies power to the driving device 30 and the vibration device 40, causing the driving device 30 and the vibration device 40 to start working. The driving device 30 drives the rotating member 51 to rotate. The rotation of the rotating member 51 drives the movable frame 52 to move back and forth, causing the two piston rods 522 to move back and forth. The back-and-forth movement of the two piston rods 522 drives the two swing rods 53 to alternately open or close with each other. When the two swing rods 53 open with each other, the two swing rods 53 drive the two brush head groups 60 to move forward along the track 13 respectively. When the two swing rods 53 close with each other, the two swing rods 53 drive the two brush head groups 60 to move backward along the track 13 respectively. In this way, the two brush head groups 60 move back and forth to horizontally wash the teeth. At the same time, the vibration device 40 works to generate vibration, and the vibration is transmitted to the two brush head groups 60 through the support frame 12, causing the two brush head groups 60 to move up and down to vertically wash the teeth. The combination of vertical washing and horizontal washing realizes a three-dimensional and all-round washing of the teeth, making the brushing cleaner and faster. At the same time, the user does not need to repeatedly move the product back and forth, saving time and effort.

[0048] The design focus of the present utility model lies in that: the transmission mechanism in this product is composed of a rotating member, a movable frame and two swing rods. By directly installing the rotating member at the output end of the driving device and driving the rotation by the driving device, and matching the clamping points on the movable frame with the track grooves on the rotating member to drive the movable frame to move back and forth, the overall structure of this product is greatly simplified, with fewer components, easier assembly, lower cost, and higher stability and reliability at the same time.

[0049] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
