  • Publication number: 20190350355
    Abstract: A drop-shaped brush head assembly is revealed. The drop-shaped brush head assembly includes a drop-shaped brush head which is formed by a plurality of bristles and a handle connected to each other. The bristles are used for combing hair and the handle is for support. The handle consists of a plurality of discharge holes on top thereof and a mounting space therein. A paint in the mounting space flows through the discharge holes of the handle and the bristles to be applied to target area. The drop-shaped design of the brush head has a pointy end on top and a larger end on bottom thereof. The pointy end allows users to control the operating angle easily while grooming fine-hair area and the larger end is used to apply the paint to large area conveniently. Thereby the brush head assembly is more convenient to use.
