Folding drawing board with drying and air-drying functions and working method of folding drawing board

Abstract

The invention discloses a folding drawing board with drying and air-drying functions and a working method of the folding drawing board. The folding drawing board comprises a drawing board body, wherein the drawing board body is formed by hinging two drawing board modules, and a heating resistance wire, a relay, a temperature sensor, a control panel, a vacuum generator and a sucking disc are arranged in each drawing board module; a function key and a sucking disc mounting hole for allowing the sucking disc part to extend out are arranged on the surface of each drawing board module; each relay is connected with the corresponding heating resistance wire and controls the opening / closing of the corresponding heating resistance wire, and each control panel is simultaneously connected with the corresponding relay, the corresponding temperature sensor, the corresponding vacuum generator and the corresponding function key; the opening / closing of each relay can be controlled according to signals of the corresponding temperature sensor and the corresponding function key, and meanwhile the opening / closing of each vacuum generator is controlled through the corresponding function key.

Description

technical field [0001] The invention relates to the technical field of painting equipment, in particular to a folding drawing board with a drying and air-drying function and a working method thereof. Background technique [0002] Art students need to bring their own drawing boards when they take the art joint examination. The current general drawing boards are 4K specifications, which are large in size and inconvenient to carry and transport. At the same time, candidates often need to apply multiple layers of paint on a piece of drawing paper when painting. If the previous layer of paint is not dry before applying the next layer of paint, the colors of the two layers of paint will mix, affecting the color of the painting. Candidates can only Waiting for the paint to dry before continuing to paint is a waste of precious exam time; moreover, if the paint is diluted, the paint will scratch and bleed through the paper, and the longer the paint is allowed to dry, the more effecti...
