Technical Field

The invention relates to the technical field of drawing equipment, in particular to a spray gun device for drawing oil paintings.

Background

The oil painting is a kind of painting made by mixing fast-drying vegetable oil (linseed oil, poppy oil, walnut oil, etc.) with pigment on canvas, linen, cardboard or wood board. At present, painters generally use brushes to draw manually.

To the less drawing demand of drawing size, the manual drawing of artist can satisfy the demands, but, when drawing size is great, the manual drawing mode is consuming time and wasting effort, and artist intensity of labour is big. The drawing is with spray gun device suitable for fortune, however, among the spray gun device, the material spraying hole size of shower nozzle is certain, and the air brushing scope is certain, if material spraying hole size is great, then can not carry out meticulous drawing, if material spraying hole size is less, then can not guarantee drawing efficiency, consequently, need frequently change the shower nozzle to adapt to different drawing demands, the change process of shower nozzle is very troublesome.
