Whiteboard eraser structure with integrated functions of chemical erasure and physical erasure

Abstract

The invention discloses a whiteboard eraser structure with integrated functions of chemical erasure and physical erasure. The whiteboard eraser is characterized in that functions of liquid storage, chemical erasure and physical erasure are combined by the aid of the integrated whiteboard eraser so that ink marks of a whiteboard pen are erased. In particular, the integrated whiteboard eraser is an integrated device which integrates the functions of liquid storage, chemical erasure and physical erasure to be used for erasing the ink marks of the whiteboard pen. The whiteboard eraser structure consists of a liquid storage frame, liquid absorbing materials, a physical erasing block and a chemical erasing block, wherein flow of erasing liquid of the chemical erasing block is controllable. After the erasing liquid is used up, erasing liquid can be added via a liquid adding port so that the whiteboard eraser structure can be reused, the physical erasing block or the physical erasing block can be conveniently disassembled after being worn, new erasing blocks can be mounted on the whiteboard eraser structure, and a whiteboard eraser structure can be reused. The whiteboard eraser is used with the whiteboard pen, is simple in structure and convenient in use, can effectively erase the ink marks, and avoids pollution of a board, and the ink marks can be erased as soon as the ink marks are written when the whiteboard pen is used by the aid of the whiteboard eraser structure.

Description

technical field [0001] The patent of the present invention relates to a method for erasing written ink marks, specifically an eraser structure for erasing whiteboard marker ink marks, which integrates liquid storage, chemical erasing and physical erasing. Background technique [0002] Erasable ink is a new type of ink with the characteristics of dust-free and easy to erase. It can erase handwriting within a certain period of time without affecting continuous writing and visual reading. It is matched with a special writing pen and is easy to carry. It is characterized by smooth writing, easy to write and erase, and no dust pollution. It is widely used in teaching, office, academic exchange and conferences and other occasions. [0003] With the development of science and technology, the requirements of human health and environmental protection, the performance of erasable ink is also constantly evolving and improving, from the early use of toxic ketones and ester organic solve...

Problems solved by technology

On the other hand, because the moisture as a solvent is not easy to volatilize, the handwriting of water-based ink contains more moisture, which is easy to stain the board, and it is difficult to realize instant erasing and writing, especially on the matt whiteboard with a rough surface that protects eyesight. Defects are more serious, so water-based whiteboard inks are usually erased with chemical wet

Chinese patent (application number: CN201010158764.5) discloses "a water-based whiteboard pen ink and its wiper that can be dry-erased and wet-erased", this ink uses dye as a developer to write on a smooth, non-absorbent board Finally, the ink can be removed by dry wiping, but in order to solve the problem of developer penetration, it is still necessary to use a reactive eraser component to wipe the ink to prevent staining.

Chinese Patent (Application No.: CN03114634.1) "Hydrolysis Blackboard Ink Composition", the ink uses a chemical reaction method to wet erase blackboard writing. After wiping, it is necessary to wait for the board surface to dry before performing the second blackboard writing. In some occasions Inconvenient to use

[0007] Based on the above reasons, the ink of water-based whiteboard markers is usually used in a two-component way. Therefore, when using water-based whiteboard markers, the corresponding erasing liquid must be carried separately at the same time. Every time you erase, you must dip or pour the erasing liquid on the board eraser. Unable to control the amount of erasing liquid, it is very inconvenient and uneconomical to use, and the excess erasing liquid will soak the whiteboard, and you need to wait for the board to dry before you can write again, which is not convenient to use
