Description

Electric toothbrush head Technical Field The utility model belongs to the field of electric toothbrushes, and particularly relates to an electric toothbrush head. Background The electric toothbrush generally transmits vibration to the brush head through the operation of the motor, and drives the electric toothbrush head to generate corresponding vibration so as to clean teeth. In the brushing process, the middle area of the brush head often serves as a main force point, the upper part and the left and right side parts of the middle area of the brush head often need a larger degree of freedom to penetrate into gaps between teeth for cleaning, and the lower part of the middle area of the brush head is used less frequently than other positions, so that the corresponding cleaning effect is weaker. The toothbrush heads in the prior art are rich in forms, the brush hair of the toothbrush heads are diversified respectively on the toothbrush heads, but in most toothbrush heads, the bristle planting part is an integral body, namely, the brush hair implanted into the integral body has the same elastic degree of freedom, and cannot be adapted to the use mode of the toothbrush in the tooth brushing process, so that the cleaning effect is poor, and the user experience is poor. Disclosure of utility model The present utility model has been made in view of the above-mentioned needs of the prior art, and an object of the present utility model is to provide an electric toothbrush head for improving cleaning efficiency and use experience. In order to solve the above problems, the technical solution provided by the present utility model includes: The electric toothbrush head comprises a soft rubber, a bristle planting part, a second bristle planting part and bristles, wherein the bristle planting part is at least partially arranged in the soft rubber, the bristle planting part comprises a first bristle planting part and a second bristle planting part, a coverage area of the first bristle planting part comprises a central bristle planting area and a lower bristle planting area, the central bristle planting area is distributed in the middle of the front face of the toothbrush head, the lower bristle planting area is distributed at the position below the toothbrush head, the bristle planting part corresponding to the central bristle planting area is connected with the bristle planting part corresponding to the lower bristle planting area, the second bristle planting part is distributed on the periphery of the front face of the toothbrush head, the second bristle planting part is arranged independently of the first bristle planting part, the bristles are arranged on the bristle planting parts, the top ends of the bristles in each bristle planting area extend out of the soft rubber, and the bristle tufts are formed by aggregation. Through the arrangement, the bristles in the first bristle planting area and the bristles in the second bristle planting area act independently of each other so as to adapt to different degrees of freedom required by different areas in the tooth brushing process, and in addition, as the frequency of the area corresponding to the lower bristle planting area in the tooth brushing process is lower than that of other parts, the association between the bristle planting part in the central area and the bristle planting part in the lower area is established by arranging the first bristle planting area so as to generate influence.
