[0024] In the specific implementation process, Figure 1 and Figure 2 As shown, a plurality of hair implantation holes 31 are connected with brush filaments 4, and the top ends of the plurality of brush filaments 4 are designed in a semi-moon arc shape.

[0025] It should be noted that: there are seventeen hair planting holes 31 on the hair planting surface 3, and the seventeen hair planting holes 31 are used to receive brush filaments;

[0026] The ten hair-planting holes 31 on the periphery are arranged along the edge line to form a ring shape;

[0027] The seven hair-planting holes 31 inside the ring are divided into two areas, and the three hair-planting holes 31 in one area are arranged vertically and diagonally on both sides to form a triangular area.

[0028] The three hair-planting holes 31 in the second zone are arranged vertically and diagonally on both sides to form a triangular area;

[0029] The two triangular areas are symmetrically distributed, and when the brush filaments 4 move forward or backward to brush the teeth, the cleaning ability in the two directions remains consistent;

[0030] The tops of the multiple brush filaments 4 are cut into a half-moon arc, with the lowest point of the half-moon arc located on the brush filament 4 in the middle of the hair planting hole 31, and gradually rising to both sides. After reaching the highest point, the brush filaments 4 at both ends continue to extend straight outward to form a plane, so that the height of the brush filaments 4 gradually increases from the base of the triangle to the tip, forming a height difference.

[0031] refer to Figure 1 and Figure 4 As shown, the neck of the brush installation position 25 is provided with two reinforcing ribs 21, the upper part of the brush installation position 25 is provided with two through holes 22, the brush piece 2 is provided with a glue overflow groove 23, and the brush installation position 25 is provided with an ultrasonic line 24.

[0032] It should be noted that the two reinforcing ribs 21 can increase the strength of the brush head and enhance the bendability of the brush head. This prevents the brush head from bending and breaking when accidentally dropped, making the brush head stronger.

[0033] The upper section of the brush piece mounting position 25 has two through holes 22 for the glue injection holes during soft glue injection, thereby avoiding the need to inject the soft glue from the outside, ensuring the overall beauty of the outer surface, and also avoiding the impact of the use experience due to unclean glue injection points.

[0034] refer to Figure 4 and Figure 5 As shown, the soft glue installation position 26 is formed by the maximum external offset of the brush head, and the shape of the soft glue installation position 26 is consistent with that of the brush head.

[0035] It should be noted that the soft rubber mounting position 26 is formed by a maximum external offset of 0.7mm from the brush head. Attached to the brush head surface, the soft rubber cover 5 acts as a shock absorber, reducing vibration stimulation and preventing tooth damage or tooth abrasion. This prevents discomfort caused by strong vibrations of the brush head hitting the teeth.

[0036] refer to Figure 1 and Figure 6 As shown, a tail hole is provided at the tail position of the brush handle 1, and a tail plug 6 is installed and connected in the tail hole. An outer disc is provided at the bottom end of the tail plug 6, and a cone 62 is provided on the outside of the outer disc. A circle of convex rings 65 is provided on the cone 62, and a rotation-stop groove 64 is provided on the cone 62. The upper end of the cone 62 is a D-shaped column 63, and the front section of the D-shaped column 63 is a square upper and lower fixing block 61.

[0037] It should be noted that: there are openings on both sides of the D-shaped column 63 that communicate with the shaft center mounting hole, and the center of the opening is a spring piece 71, which is used to adjust the tightness of the shaft center mounting;

[0038] The front section of the D-shaped column 63 is a square upper and lower fixing block 61, which together with the upper and lower fixing cavities fix the tail plug 6 to prevent it from moving up and down;

[0039] A raised ring 65 is provided on the cone 62 to ensure that the tail plug 6 is more convenient and secure during installation.

[0040] refer to Figure 1 and Figure 6 As shown, a D-shaped cavity is provided in the tail hole, a limiting bone is provided on each side of the D-shaped cavity, a square cavity is provided at the front end of the D-shaped cavity, an axial mounting hole 7 is provided inside the D-shaped column 63, a spring piece 71 is provided on the inner side wall of the axial mounting hole 7, and a protrusion is provided on the spring piece 71.

[0041] It should be noted that there is a D-shaped cavity in the tail hole for installing the D-shaped column 63;

[0042] There is a limiting bone on each side of the D-shaped cavity, called the left and right limiting bones, which are used to limit the left and right displacement of the D-shaped column 63.

[0043] There is a square cavity at the front end of the D-shaped cavity, which is an upper and lower fixed cavity. It interacts with the upper and lower fixing blocks 61 of the tail plug 6 to fix the tail plug 6 so that it cannot move left and right or up and down, avoiding vibration due to looseness.

[0044] The tail plug 6 is conical, with a large bottom and a small head;

[0045] The spring piece 71 is designed with a convex point, which is matched with the concave position of the main body axis to prevent the main body axis from escaping from the tail plug 6 during use.

[0046] The working principle of the copper-free rubber-coated electric toothbrush head provided by the present invention is as follows: the ultrasonic line 24 is used to drive multiple brush wires 4 to vibrate accordingly. When the brush wires 4 move forward or backward to brush the teeth, the semi-lunar arc at the top of the brush wire 4 fits the tooth surface, and the brush wires 4 at both ends swing with a larger amplitude relative to the brush wire 4 in the middle position. The long brush wires 4 with a larger swing amplitude can enter the gaps between teeth, thereby achieving excellent cleaning of dirt deep inside.
