Abstract

A bristle tuft assembly, comprising a bristle tuft, a compression plate, a base, and a base support plate, the base is configured with an accommodation chamber which has a wide top and a narrow bottom, forming a reversed splayed shape. The base support plate is placed horizontally and fits into the bottom of the accommodation chamber, the compression plate is placed vertically and fits into the accommodation chamber, the middle part of the bristle tuft is compressed and fixed between the vertically placed compression plate and the horizontally placed base support plate, both ends of the bristle tuft go through the space in the accommodation chamber and are set up and exposed outside the base. Further provided is a toothbrush device, comprising the above mentioned bristle tuft assembly. The bristle tuft assembly occupies little room, and a toothbrush device can easily accommodate multiple bristle tuft assemblies, and the bristle tuft of the assembly is firmly fastened, not easy to fall off, and the multiple bristle tuft assemblies on the toothbrush device can flexibly and independently move in different directions.
