Writing and painting device based on magnetic liquid

Abstract

The invention discloses a writing and painting device based on magnetic liquid. The writing and painting device based on the magnetic liquid comprises a writing board and a magnetic pen; the writing board comprises an upper transparent panel, a magnetic translucent membrane, a lower transparent panel, a magnetic liquid box, the magnetic liquid, a bottom shell and a demagnetization plate which is capable of dismounting from the lower portion of the bottom shell; the magnetic pen comprises a pen rod, a magnet and a magnetic conductive rod; the magnetic conductive rod comprises a connecting end which is connected with the magnet and a writing end which is used for magnetizing the parts, which are corresponding to a moving trajectory, of the magnetic translucent membrane and the magnetic liquid when the magnetic conductive rod moves on the upper transparent panel; a magnetic particle short chain rises on a magnetic liquid surface after the magnetic translucent membrane and the magnetic liquid are magnetized and the top of the magnetic particle short chain adheres to the lower transparent panel to form a handwriting; the writing end extends out of a mounting hole; the demagnetization plate comprises a handwriting removing surface with a magnetic field reverse to the writing end; when the handwriting removing surface is located below the magnetic liquid box, the magnetic translucentmembrane and the magnetic liquid are demagnetized by the reverse magnetic field to remove the magnetic particle short chain. The device is more in represented handwriting effect and stronger in art expressive force.

Description

technical field [0001] The invention relates to a painting and calligraphy device, in particular to a painting and calligraphy device based on magnetic fluid. Background technique [0002] Magnetic fluid, also known as magnetic liquid, is a new type of functional material. It is not a liquid state of magnetic materials, but highly dispersed ultrafine magnetic particles (about 10nm) treated with surfactants in the base liquid to form a magnetic colloidal solution. Magnetic particles are usually composed of metals such as Fe3O4, Σ-Fe2O3, Ni, Co, and Fe, and exhibit magnetism. The base fluid can be a liquid substance such as water, organic solution, hydrocarbon, and mercury, or a combination of formulas, which makes the magnetic fluid also have the properties of a fluid. The particle size in the ferrofluid is very small, which can be regarded as single domain or near single domain, so it has the characteristics of spontaneous magnetization. These magnetic particles are in th...

Problems solved by technology

However, both magnetic powder and magnetic beads are lacking in the control and expressiveness of handwriting, mainly due to the existence of small storage structures, which make the pixel area too large or the handwriting is not continuous

These magnetic drawing boards are difficult to meet the expressive requirements of traditional calligraphy and painting art in terms of skills and techniques, and can only be used in the field of simple calligraphy and painting
