Abstract
The utility model provides an automatic blackboard eraser which is formed by a blackboard, an electric blackboard eraser body, slide rails, travel switches, a dust collecting groove and a switch. A blackboard is in a rectangular shape. The slide rails are arranged on two sides of the blackboard. The travel switches are arranged on the upper end portions and the lower end portions of the slide rails. The dust collecting groove is arranged on the lower portion of the blackboard. The switch is arranged on one side of the blackboard. When the switch is started, the electric blackboard eraser body moves up and down to erase the blackboard. When the electric blackboard eraser body moves to the travel switch arranged on the lower portions of the slide rails, the electric blackboard eraser body stops, and then moves upward to reset, the electric blackboard eraser body moves to the upper portion of the blackboard, contacts with the travel switches on the upper portions of the slide rails and stops, and then the erasing of the blackboard is finished. The automatic blackboard eraser is simple in structure, convenient to operate, reasonable in design, and strong in practicability, and reduces damages caused by splashing of dust, does not pollute environment, reduces burden of manual blackboard erasing, and improves blackboard erasing efficiency.
Description
Technical field
The utility model relates to a kind of blackboard eraser, relates in particular to a kind of automatic blackboard eraser.
Background technology
Blackboard eraser is the specific purpose tool that is used for erasing the board, the structure of blackboard eraser is all very simple, constitute by sponge and shell, the use of conveniently taking, be easy to the dust on the blackboard is wiped clean, in the blackboard wiping process, the dust of wiping can fly away with the wind, if these dust are scattered on the clothes, the meeting intractable is clean; If be drawn in the lung by people with air, can damage healthyly, the mode that this manually-operated erases the board is the not high but also waste muscle power of efficient not only.
Summary of the invention
Main purpose of the present utility model is to solve above-mentioned blackboard eraser problem in use, and a kind of automatic blackboard eraser is provided.
The technical scheme that its technical problem that solves the utility model adopts is:
Form by blackboard, electric eraser, slideway, travel switch, dust collection groove and switch, blackboard integral body is rectangular, the both sides of blackboard are installed slideway respectively, electric eraser moves along slideway, install micromachine in the electric eraser, drive the electric eraser operation, install sponge on the electric eraser, the sponge of electric eraser closely contacts with the plate face of blackboard, wipes the letter written with chalk on the blackboard during operation.
Travel switch is installed at the both ends up and down of the slideway of both sides respectively separately, and the control electric eraser is in the interior operation of scope of blackboard, and the dust collection groove is installed in the bottom of blackboard, and the dust collection groove is collected the chalk powder that the electric blackboard eraser wiping is got off.
One side of blackboard is installed switch, the starting switch electric eraser moves blackboard wiping from top to bottom, run to the travel switch that is installed in the slideway bottom, electric eraser stops at once, and upwards operation resets, electric eraser runs to the top of blackboard, touches the travel switch that is installed in slideway top and stops at once, and blackboard wiping finishes.
The utility model is an automatic blackboard eraser.Simple in structure, easy to operate, reasonable in design, practical, reduced the harm that dispersing of dust brought, do not pollute the environment, reduced the burden that manually erases the board, improved the efficient that erases the board.
