Toothbrush head

摘要

The invention is related to a toothbrush head which comprises a head base, a head frame, and bristles. The head base comprises a front end, a back end, multiple strip-substrates, and multiple junctions. The multiple strip-substrates are aligned between the front end and the back end and each two adjacent strip-substrates link with each other with each of the multiple junctions, and each of the multiple strip-substrates comprises multiple sockets for inserting the bristles. The head frame comprises a bottom surface and multiple accommodating spaces for accommodating the head base. The toothbrush head allows the bristles to be bent into the arc shape when touching the teeth, so as to increase touching areas between the brushes and the teeth for enhancing cleaning effect and decreasing risks of causing caries.
