The specific implementation mode is as follows:

in order to enhance the understanding of the present invention, the following detailed description will be made in conjunction with the embodiments and the accompanying drawings. The utility model discloses the accessible is implemented as follows:

referring to fig. 1-4, a rotary toothbrush head comprises a bristle-implanting base assembly 1, wherein outer ring bristles, inner ring bristles and center bristles are sequentially inserted into the bristle-implanting base assembly 1 along the radial direction inwards.

The outer ring bristles and the inner ring bristles respectively comprise a plurality of inclined bristles 2 which are circumferentially distributed and have the same inclined direction and a vertical non-inclined bristle 3, and the vertical non-inclined bristle 3 is vertical at 90 degrees and has no inclination. The design can improve the contact surface between the toothbrush head and the teeth, so that the toothbrush head can go deep into the gaps between the teeth from a plurality of angles to clean food residues and bacteria. The inclined rotating directions of the inclined bristles 2 of the outer ring bristles and the inner ring bristles are opposite to each other to form two opposite bristle directions, so that the cleaning effect is enhanced in the process of back-and-forth tooth brushing. The number of the outer ring bristles is 16, the number of the inner ring bristles is 8, and each bristle is a round hole implanted bristle with the diameter of 1.5 mm. The rotation inclination angle of the inclined bristles 2 of the outer ring bristles and the inner ring bristles is more than 0 degree and less than or equal to 15 degrees. The optimum scheme of the rotation inclination angle of the inclined bristles 2 of the outer ring bristles and the inner ring bristles is 15 degrees.

A plurality of clusters of inclined bristles 2 of the outer ring bristles and the inner ring bristles are divided into long bristles 21 and short bristles 22, the long bristles 21 and the short bristles 22 are distributed at intervals, the difference degree of contact surfaces of the toothbrush head and teeth is further increased, and the cleaning effect is further enhanced.

The central brush hair is four vertical brush hair 4 with the end surfaces in a pyramid shape. The end of the central brush hair with the reduced size faces to the circle center. This design can not only increase the contact surface of brush hair and tooth, and the radian of the one end of its size grow is laminated more with the radian between tooth and the gum, when electric toothbrush drives the clean tooth of toothbrush head rotation work, can more effectual clean tooth face, improves clean effect.

As shown in fig. 5, the roots of the inclined bristles 2, the vertical non-inclined bristles 3 and the vertical bristles 4 are provided with copper 5 for reinforcing the bristles. When the bristles are planted, the bristles and the copper seeds 5 are planted on the bristle planting disc together. The copper 5 can play a stable supporting role and can improve the lodging resistance of the brush hair.

The hair-planting seat assembly 1 comprises a hair-planting disk 11 and a hair-planting lower seat assembly 12 sleeved on the hair-planting disk 11, and outer ring bristles, inner ring bristles and center bristles are planted on the hair-planting disk 11. The hair planting disc 11 is provided with brush pores for implanting outer ring bristles, inner ring bristles and central bristles. The bristle holes include circular holes 111 having the same number as the outer ring bristles and the inner ring bristles, and pyramid-shaped holes 112 having the same number as the central bristles.
