fig. 2 is a schematic structural view of the swing pin according to the present invention.

Detailed Description

For better understanding of the technical solutions of the present invention, the following describes the embodiments of the present invention in detail with reference to fig. 1 and 2.

Example 1: an electric toothbrush, comprising: motor 1, eccentric pivot 2, swing arm 3 and toothbrush head 4, motor 1 with eccentric pivot 2 rotates the connection, eccentric pivot 2 with swing arm 3 connects, swing arm 3 with toothbrush head 4 connects. In this embodiment, motor 1 rotates, drives eccentric pivot 2 rotates, eccentric pivot 2 drives swing arm 3 swings, toothbrush head 4 passes through first swing pin 6 with swing arm 3 connects, makes toothbrush head 4 simulation manual mode of brushing teeth, and free swing can deep clean tooth guarantee.

Example 2: an electric toothbrush, comprising: motor 1, eccentric pivot 2, swing arm 3 and toothbrush head 4, motor 1 with eccentric pivot 2 rotates and connects, eccentric pivot 2 with swing arm 3 connects, swing arm 3 through first swing pin 6 with toothbrush head 4 connects, toothbrush head 4 uses first swing pin 6 to swing as the central point multi-angle.

In this embodiment, the toothbrush head 4 is connected with the swing arm 3 through the first swing pin 6, the toothbrush head 4 can swing at multiple angles through the first swing pin 6, and in the using process, how a human hand holds the main housing 9 can enable the toothbrush head 4 to be always attached to teeth, so that the teeth can be cleaned deeply.

On the basis of the embodiment, more specifically, the lower end of the swing arm 3 is provided with a groove, the upper end of the eccentric rotating shaft 2 is provided with a convex ball, and the convex ball on the eccentric rotating shaft 2 slides in the groove at the lower end of the swing arm 3. In other embodiments, it is fluted to swing arm 3 lower extreme, 2 upper ends of eccentric pivot have a protruding ball, and this protruding ball can swing arm 3 lower extreme fluted of sliding, will swing arm 3 with eccentric pivot 2 is connected, works as when eccentric pivot 2 rotates, the protruding ball of 2 upper ends of eccentric pivot is in swing arm 3 lower extreme fluted of sliding, thereby drives swing arm 3's swing, and then drive toothbrush head 4 swings, carries out deep cleanness to the tooth.

In addition to the above embodiments, a second swing pin 5 is provided at the upper portion of the concave groove of the swing arm 3, and the swing arm 3 swings left and right around the second swing pin 5. In other embodiments, the second swing pin 5 is located at the upper portion of the groove of the swing arm 3, and when the convex sphere at the upper end of the eccentric rotating shaft 2 slides in the groove at the lower end of the swing arm 3, the swing arm 3 can swing left and right around the second swing pin 5, so that the toothbrush head 4 can swing up and down along the gap between teeth during use.
