Abstract

The invention discloses a blackboard eraser. The blackboard eraser comprises two guide rails and an eraser, wherein the two guide rails are fixed at the upper and lower edges of a blackboard respectively; the eraser can slide left and right along the two guide rails; the eraser comprises a strip-shaped plate, two stepping motors, erasing cotton and a dust collector; the length of the strip-shaped plate is matched with the width of the blackboard; the two stepping motors are fixed at the two ends of the strip-shaped plate respectively; pulleys are arranged on rotating shafts of the two stepping motors; the pulleys are matched with the corresponding guide rails; the strip-shaped plate is clamped on the two guide rails by the pulleys; the erasing cotton is detachably arranged on the inner side of the strip-shaped plate and is closely fitted with the blackboard; the dust collector is arranged on the inner side of the strip-shaped plate on the two sides of the erasing cotton. The blackboard eraser has an erasing area and has no dust.

Description

Blackboard eraser
Technical field
The present invention relates to teaching equipment field, particularly a kind of blackboard eraser.
Background technology
The teaching occasions of the overwhelming majority, blackboard can't do without obtaining educational aid, at present, traditional blackboard is manual, and writer writes has expired monoblock blackboard, oneself is picked up blackboard eraser and erases the board, the result caused is that chalk produces a large amount of dust, descends slowly and lightly on the body of people, is scattered on the ground, most importantly writer can suck respiratory system the dust of chalk, produces great harm to the respiratory system of human body.And traditional blackboard eraser is all very little one piece, the process of wiping often needs for a long time, wastes valuable instructional blocks of time.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide a kind of blackboard eraser, erasing area is large, without dust.
For achieving the above object, the invention provides a kind of blackboard eraser, comprising: two guide rails, it is separately fixed at the lower edges of blackboard surface; And eraser, it can horizontally slip along two guide rails, and eraser comprises: stripe board, and its length is mated with the width of blackboard surface; Two stepper motors, it is separately fixed at the two ends of stripe board, and the turning cylinder of two stepper motors is equipped with pulley, and pulley coordinates with corresponding guide rail, and stripe board is fastened on two guide rails by pulley; Erasing is cotton, and it is dismountable is located at the inner side of stripe board and is adjacent to blackboard surface; And dust catcher, it is located at the inner side of the stripe board of wiping cotton both sides.
Preferably, two stepper motors are embedded with single-chip microcomputer, the rotating of Single-chip Controlling stepper motor.
Preferably, blackboard surface both sides be equipped with button, button sends rotating signal to single-chip microcomputer.
Compared with prior art, the present invention has following beneficial effect: by arranging moveable eraser, eraser can be moved left and right by driving stepper motor, and can by pressing key control, and realize erasing automation, wiping is fast, saves time.Dust catcher is set simultaneously, in the process of wiping, siphons away dust, clean hygiene simultaneously, healthy.

Fig. 1 is the schematic diagram according to blackboard eraser of the present invention;
Fig. 2 is the structural representation of the eraser according to blackboard eraser of the present invention.
Main Reference Numerals illustrates:
1-staple, 2-guide rail, 3-eraser, 4-blackboard surface, 5-wipes cotton, 6-dust catcher, 7-stepper motor, 8-button.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole description and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or part, and do not get rid of other element or other part.
As shown in Figures 1 and 2, according to a kind of blackboard eraser of the specific embodiment of the invention, comprise two guide rails 2 and eraser 3, wherein two guide rails 2 are separately fixed at the lower edges of blackboard surface 4, and particularly, guide rail 2 can be fixed by staple 1.Eraser 3 can horizontally slip along two guide rails 2, eraser comprises stripe board (unmarked in figure), two stepper motors 7, erasing cotton 5 and dust catchers 6, particularly, the length of stripe board is mated with the width of blackboard surface 4, two stepper motors 7 are separately fixed at the two ends of stripe board, the turning cylinder of two stepper motors 7 is equipped with pulley, and pulley coordinates with corresponding guide rail 2, and stripe board is fastened on two guide rails 2 by pulley.Erasing cotton 5 is dismountable to be located at the inner side of stripe board and to be adjacent to blackboard surface 4, and erasing cotton 5 is replaceable, and dust catcher 6 is located at the inner side of the stripe board of wiping cotton 5 both sides.
In addition, the blackboard eraser of the present embodiment can realize automation, namely single-chip microcomputer is embedded with at two stepper motors 7, Single-chip Controlling stepper motor 7 rotating, now, blackboard surface 4 both sides be equipped with button 8, button 8 sends rotating signal to single-chip microcomputer, particularly, press the button 8 in left side, Single-chip Controlling stepper motor 7 drives eraser 3 to be moved to the left, and in like manner, presses the button 8 on right side, Single-chip Controlling stepper motor 7 drives eraser 3 to move right, meanwhile, Single-chip Controlling dust catcher 6 works, and can siphon away the dust wiping cotton 5 both sides.
To sum up, the blackboard eraser of the present embodiment is by arranging moveable eraser 3, and eraser 3 can be driven by stepper motor 7 and move left and right, and can be controlled by button 8, and realize erasing automation, wiping is fast, saves time.Dust catcher is set simultaneously, in the process of wiping, siphons away dust, clean hygiene simultaneously, healthy.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
