Background

Painting and calligraphy are popular in families as traditional special skills, and daily cleaning and maintenance of paintbrushes are inconvenient and cannot be effectively solved. The cleaning mode of the painting brush is mainly divided into two types: one is to wipe with rag or paper towel after repeatedly moistening with a large amount of color-adjusting oil; the other method is to wash the painting pen by using tap water, and in the washing process, after a pen point is smeared with soap, the pen point is rotated in the palm according to one direction, and the pigment in the pen is extruded by using fingers. Although the first method is simple in steps, the use of color mixing oil, cleaning cloth and paper towels wastes resources and generates garbage polluting the environment, in addition, the method is only suitable for cleaning the oil painting brush which is used repeatedly in a short time, if the oil painting brush is not used for a long time after being cleaned by the method, the color mixing oil remained at the pen point can be solidified, and the aging of the oil painting brush is accelerated. Although the second method is suitable for cleaning oil painting brushes which are not used for a long time, in the cleaning process, a pen point is easy to hurt the palm of a cleaner, in addition, in the cleaning process, pigment is easy to splash on clothes, in addition, in the cleaning process, a water tap is always in an open state, because the painting brush is used for coating soap and pressing for several times, the mixture of the pigment and the soap needs to be cleaned in time, the time for cleaning one oil painting brush is averagely six minutes, a large amount of waste of water resources is caused, in winter, tap water is cold to stab bones, the number of the painting brushes cleaned at one time is usually more than five, and after the oil painting brush is cleaned, the hands of the cleaner are often frozen and injured.
