 Wherein, the bristles are conical.

 Wherein, the bristles have a triangular pyramid shape.

 Wherein, the bristles are arranged equidistantly on the outer ring surface of the brush bar.

 Wherein, the plurality of through holes are arranged equidistantly.

 The utility model has the beneficial effects:

 1. The utility model adopts a hollow structure brush and a hose design, which can be easily squeezed, does not need to adhere to the mascara liquid multiple times, and the action of the piston rod and the spring, together with the tightness of the outer cover , can be very convenient for users to use.

 3. The bristles and brush bars of the utility model are integrally formed by soft material injection, which can effectively simplify the process and accurately arrange the bristles evenly on the brush, effectively solving the precision in the process of rolling the traditional brush bristles. Problems that are difficult to control.

 With regard to the technology, the means and the functions of the present invention, the preferred embodiment and the detailed description of the drawings are as follows. It is believed that the above objects, structures and features of the present invention can be obtained from Specific understanding. DRAWINGS
