When the secondary structure 1212 is a first slider 12122 and the driven structure 12211 is a second slider 122112, the angle between the first segment 12111 and the second segment 12112 changes.

As an embodiment, when the connecting member 1221 is driven to rotate by the connecting member 121, the connection portion between the first segment 12111 and the second segment 12112 is elastically deformed, and the position of the limiting member 124 corresponding to the connection portion between the first segment 12111 and the second segment 12112 defines a deformation space 1241, and the first segment 12111 and/or the second segment 12112 can deform to a certain extent in the deformation space 1241, so that the connecting member 1221 can be driven to rotate smoothly by the connecting member 121.

It can be appreciated that the connection between the first segment 12111 and the second segment 12112 can be elastically deformed, so that the linkage member 121 can play a role in buffering, and prevent the connecting member 1221 from rotating too hard and stimulating, thereby improving the uniformity of rotation of the cleaning member 1222 and further improving the use experience of the electric toothbrush 1.

As another example, the first segment 12111 is rotatably connected to the second segment 12112, and when the linkage 121 rotates the connecting member 1221, the second segment 12112 rotates within a certain threshold relative to the first segment 12111. It will be appreciated that the rotational connection of the first segment 12111 and the second segment 12112 allows the linkage 121 to provide a cushioning effect, and prevents the connector 1221 from rotating too hard and irritating, thereby improving the uniformity of rotation of the cleaning member 1222 and thus improving the use experience of the electric toothbrush 1.

The arc-shaped design of the side of the linkage member 121, which is close to the gear 122111, can increase the contact distance between the tooth slot 12121 and the gear 122111, so that the rotation angle of the gear 122111 is further increased, and the cleaning force of the electric toothbrush 1 is further ensured. The opposite sides of the gear 122111 are provided with tooth grooves 12121, which can further improve the rotation force of the driving gear 122111, thereby further ensuring the cleaning force of the electric toothbrush 1.

Specifically, when the auxiliary structure 1212 is a tooth slot 12121 and the driven structure 12211 is configured as a gear 122111, the gear 122111 is disposed on a side of the connecting member 1221 facing away from the cleaning member 1222. That is, the output shaft 1121 drives the connecting rod 1211 to axially reciprocate through the connecting sleeve 1213, so as to drive the tooth slot 12121 to axially reciprocate, and the tooth slot 12121 drives the gear 122111 to rotate in the same direction, and the gear 122111 rotates to drive the connecting member 1221 to integrally and coaxially rotate, and the connecting member 1221 drives the cleaning member 1222 to rotate.
