Description

Automatic oil painting brush

Technical Field

The invention relates to an automatic oil painting brush, and belongs to the technical field of oil painting brushes.

Background

At present, the known oil painting brushes are ones with traditional structures which have been existed for hundreds of years, and the traditional oil painting structure is formed by combining a wooden/plastic penholder, a bristle/howline/nylon fiber pen point, a metal connecting accessory and glue. Traditional oil painting brush, itself does not have pigment, need squeeze pigment to the color palette on, reuse oil painting brush dips in the color palette and transfers pigment to mix colours the drawing. The traditional oil painting has the disadvantages that the working procedure is complicated, the painting brush and the tube-packed pigment occupy more space, and the work of washing the painting brush after each use is very dirty and troublesome. The common traditional oil painting brush has the use habit of multi-color in one stroke, which is not beneficial to the maintenance and the differentiation of colors.

Disclosure of Invention
