Abstract
The utility model relates to an electric and mechanical eraser which belongs to the technical field of eraser cleaning devices for writing or drawing appliances. The utility model is composed of a fan, a motor, a guide track, a sliding board, a crossed rotary brush and a dust storing device and is characterized in that when the utility model is in a working state, a button is pressed down, the motor is started, part of motive power is transferred to pulley wheels on the sliding board through a speed changer to make the sliding board make reciprocating motion left and right, and part of the motive power is transferred to the crossed rotary brush to make the crossed rotary brush rotate to erase words. In addition, the utility model also has the advantages of simple structure, easy manufacture and wide use and is an electric and mechanical eraser with practical value.
Description
The utility model relates to an a kind of electrically powered machine blackboard eraser.Belong to by International Patent Classification (IPC) (IPC) and to write or the technical field of drawing article blackboard eraser cleaning device.Be numbered B43L21/00.
At present, have now with the technology about the dust-collecting type electric eraser that once had and to reducing dust very fruitful effort was all done in the requirement of teachers and students' harm, the technology of many aspects is used having obtained certain promising result in production and the teaching practice.Aspect dust suction, the dust control technology be a routine of great value invention as existing Chinese patent application No. 94241441.1 disclosed " dust-collecting type electric blackboard erasers ", it has solved effectively wipes dust quilt collected difficulty again.But still have some deficits, it also be difficult to solve teacher (or student) requirement big to the arm power moving amount when manually erasing the board, (especially to the physique chump), and to the course of a large amount of writings on the blackboard of needs, erasing the board just seems wastes time and energy.
The purpose of this utility model is to provide a kind of electrically powered machine blackboard eraser, replaces erasing the board by hand and preventing dust the problem of dust suction to solve with machinery.It helps to facilitate aspect culture and education.
The purpose of this utility model is achieved in that a kind of electrically powered machine blackboard eraser of this utility model.Mainly constitute by guide rail, cross rotating brush, fan, motor, slide plate.The cross rotating brush is installed on slide plate, slide plate is connected on the guide rail, connect on fan, rotating brush and the slide plate by motor, make the automatic move left and right of slide plate, fan and brush rotate, and then reach and finish the requirement that dust is removed in automatic blackboard cleaning and suction, so just realized the purpose of this utility model better.
The utility model has been compared two advantages and improvement with the technology of original electric dust absorption blackboard eraser; The first, this novel blackboard eraser replaces manual labor merit by mechanical device fully, and the second, adopt the cross rotating brush will improve the efficient of blackboard eraser greatly, save the classroom quality time.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the overall structure schematic diagram of a kind of electrically powered machine blackboard eraser of the utility model;
Fig. 2 is the slide plate A-A structural representation of a kind of electrically powered machine blackboard eraser of the utility model;
The numbering of parts explanation in the schematic diagram:＜1〉fan＜2〉motor＜3〉guide rail＜4〉slide plate＜5〉cross rotating brush＜6〉dust storage device
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, a kind of electric eraser of the present utility model is mainly by fan＜1 〉, motor＜2 〉, guide rail＜3, slide plate＜4, cross rotating brush＜5, dust storage device＜6 consist of, In blackboard＜7〉up and down both sides guide rail＜3 are installed, in guide rail＜3〉install slide plate＜4 〉, in slide plate＜4〉cross rotating brush＜5 are installed, slide plate＜4〉lower end motor is installed＜2 〉, slide plate＜4〉upper end is equipped with fan＜1 and dust storage device＜6, motor＜2 〉, revolve Turn to brush＜5 〉, fan＜1 implement with being electrically connected. Slide plate when not working＜4〉be in position A's Push button is pressed in ultra-Left original position when work, motor is activated, by speed changer, with a part Power is passed to slide plate＜4〉on pulley so that slide plate＜4〉about move back and forth a part of power Pass to cross rotating brush＜5 〉, make its rotation wipe font, another part power is passed to fan＜1 〉, Suck dust storage device＜6 with wiping the dust that falls〉in. So just realized the purpose of this utility model. From And just can solve the machine automatization problem dustproof, dust suction that erases the board.
Below by embodiment, the utility model is done more detailed description:
Embodiment 1, in use, if the capacity gauge of dust descends, can open dust storage device＜6〉remove the dust collected, can reuse then, font wipe ability drop, can change cross rotating brush＜5 〉, this shows that this electric machine blackboard eraser can reach high service life.
Utilize the basic equipment of common mechanical factory, take continuous productive process to produce by batch,, so just can realize practical value of the present utility model and economic worth better to supply the demand of vast culture and education circle.
