Multi-function board eraser structure

Abstract

A multi-function board eraser structure includes a dust-collecting device, a flexible pipe, a wiping absorber opening and a mobile guiding track. The dust-collecting device is small in volume, has intense absorbing forces and is capable of moving about as well as being devised with a light-indicative power switch, an overload protective fuse base, an overheating protective indication lamp, and a dust-collecting chamber saturated pressure switch display. Above the dust-collecting chamber are a dust-collecting breach and a scraping plate for absorbing dust accumulated at the wiping absorber opening for restoring the wiping absorber opening to an optimal status for further usage. The wiping absorber opening has a wiping plane, which is an arched body for gathering chalk dust at a middle section of the main body during a wiping process and is made of a highly elastic material for facilitating dust collection. The wiping plane is covered by a velvet plane that is highly electrostatic and wear-resistant. Thus, the velvet plane not only favors collection of dust being wiped off but offers replacement conveniences.

Description

BACKGROUND OF THE INVENTION[0001](a) Field of the Invention[0002]The invention relates to a board eraser structure, and more particularly, to a board eraser structure having a small volume, intense absorbing forces, significant dust-collecting effects, excellent safety and convenient mobility.[0003](b) Description of the Prior Art[0004]In daily life, it is rather difficult to clean tiny dust or dirt having minute volumes, light masses and strong adhesive forces merely using common sweeping means. Thus, dirt and dust are generally cleaned by wiping or rubbing methods. During a process of wiping, dust and dirt originally attached to surfaces of an object can indeed be eliminated; however, the dust and dirt that come off the surface of the object frequently become floating in the air and are much likely be hazardous when inhaled into human lungs.[0005]Therefore, supposed dust and dirt that come off from surfaces of an object are immediately absorbed using a dust-collecting device when ...

AI Technical Summary

Benefits of technology

[0008]Furthermore, the wiping absorber opening is provided with an ergonomic box-like main body having a wiping plane, which is an arched body for gathering chalk dust at a middle section of the main body during a wiping process and is made of a highly elastic material for facilitating dust collection. The wiping plane is covered by a velvet plane that is highly electrostatic and wear-resistant. Thus, the velvet plane not only favors collection of dust being wiped off but offers replacement conveniences. More particularly, dust and dirt accumulated at a surface of the velvet plane are absorbed using a dust-collecting breach and a scraping plate disposed above the dust-collecting chamber, thereby restoring the wiping absorber opening to an optimal status for further usage.

Problems solved by technology

In daily life, it is rather difficult to clean tiny dust or dirt having minute volumes, light masses and strong adhesive forces merely using common sweeping means.

During a process of wiping, dust and dirt originally attached to surfaces of an object can indeed be eliminated; however, the dust and dirt that come off the surface of the object frequently become floating in the air and are much likely be hazardous when inhaled into human lungs.

Yet, prior board eraser structures are hardly considered as practical for that they are large in volume, have little absorbing forces and are incapable of moving about.

In addition, most prior board eraser structures lack related safety designs, such that they are prone to damages due to current overload or machinery overheating.

Also, dust located in crevices and grooves cannot be effectively eliminated using the prior board eraser structures, and are instead likely inhaled into human lungs to add another shortcoming to the prior board eraser structures.
