Problems solved by technology

[0004] However, the above-mentioned patents still have the following problems: 1. When the magnetic pen is writing, its magnetism will affect the adjacent magnetic sheet, resulting in different thickness of writing, which affects the use; 2. In the daily teaching of Korean, the large magnetic pen used by teachers As far as the board is concerned, it is more troublesome to use a magnetic eraser to erase; 3. Only one side can be used, and it cannot be used in reverse

Abstract

The invention relates to a magnetic type teaching board for Korean teaching. The magnetic type teaching board comprises an image display board and a magnetic ball, wherein the image display board comprises a first image display board, a second image display board, an iron copper sandwich board, a first primer layer, and a transparent film, and the magnetic ball comprises an injection molding ball, a magnetic needle, a second primer layer, and an image display paint layer. A production method of the magnetic type teaching board for the Korean teaching comprises the following steps: 1. producing the first image display board; 2. producing the second image display board; 3. producing the magnetic ball; 4. forming by fixing. A use method of the magnetic type teaching board for the Korean teaching comprises the following steps: 1: writing; 2. erasing the writing.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a magnetic suction teaching board for teaching Korean and its manufacturing method and usage method. Background technique [0002] The magnetic board is an eco-friendly, reusable writing instrument. The structure of the existing magnetic drawing board comprises a plastic frame, in which a plastic display panel, a grid, and a sliding magnet that can move back and forth laterally along the plastic frame are fixed sequentially from top to bottom in the plastic frame, and a white translucent plastic is arranged on the top. The display board is also called a magnetophoretic display board, and the grid is set under the magnetophoretic display board. Dark iron powder is placed in the grid, and a pen with a magnet at the end is used to draw and write on the magnetophoretic display board. At the same time, the iron powder in the grid will be adsorbed and attached to the bottom...
