Abstract
The invention discloses a method for preventing drop of brush hair of a whiteboard eraser and the whiteboard eraser thereof. Two clamping doors which are electrically controlled are arranged for clamping the brush hair, and meanwhile a brush hair clamping switch is used for controlling the tightness degree for the clamping door to clamp the brush hair so as to realize the aim of preventing the drop of the brush hair. The whiteboard eraser comprises an erasing plate (6), wherein a plurality of layers of protruding brush hair (4) are arranged on the front surface of the erasing plate (6); a battery (3) is arranged on a battery jar in the back surface of the erasing plate (6); two clamping doors (5) for clamping the plurality of layers of brush hair (4) on the erasing plate (6) are respectively arranged on the two sides of the erasing plate (6). By adopting the method in the technical scheme disclosed by the invention, the drop of the brush hair of the whiteboard can be prevented during teaching of a teacher; the utilization efficiency of the whiteboard eraser is improved; the clamping doors and the electric whiteboard eraser can share one battery, so the structure is compact; meanwhile, the whiteboard eraser is attractive in appearance, convenient to use and worthy of promotion.
Description
Technical field
The present invention relates to teaching aid technical field, relate in particular to the method that the anti-snag of a kind of whiteboard eraser comes off and the snag anticreep whiteboard eraser improved according to the method.
Background technology
At present, the teaching white board wiping that school of China uses has various, but all there is certain problem.Wherein traditional whiteboard eraser is time-consuming, effort, service life are short and snag is easy to come off with wiping board come; Long-Time Service affects the operating efficiency of teachers and students, and snag uses for a long time can be very dirty, impact teaching.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming and method that the anti-snag of a kind of whiteboard eraser that provides comes off and the snag anticreep whiteboard eraser that improves according to the method.
Object of the present invention and solve its technical problem underlying and realize by the following technical solutions:
The present invention first proposed the method that the anti-snag of a kind of whiteboard eraser comes off, the method clamps snag by arranging two fans by the clamping door of Electronic control, opened the elasticity controlling clamping door clamping snag by snag clamping switch simultaneously, thus the object that realization prevents snag from coming off.
According to such method, the present invention proposes a kind of snag anticreep whiteboard eraser of improvement, it comprises wiping board, is provided with protruding multilayer snag, in the battery case at the back side of wiping board, is provided with battery in the front of wiping board; A fan is respectively provided with for described multilayer snag being clamped in the clamping door on wiping board in the both sides of wiping board.
Further, the multilayer snag of projection clamps by described clamping door in the middle part of two side direction of wiping board.
Further, multilayer snag is connected with wiping board by tumbler with biparting clamping door.
Further, tumbler has two, is symmetricly set on the side of wiping board.
Owing to have employed technical scheme of the present invention, can prevent teacher's the coming off of whiteboard eraser snag in teaching process, improve whiteboard eraser service efficiency, wipe due to clamping door and electric whiteboard and can share a battery, structure is also very compact.Meanwhile, this whiteboard eraser handsome in appearance, easy to use, is worthy to be popularized.

Fig. 1 is whiteboard eraser front view of the present invention;
Fig. 2 is whiteboard eraser side view of the present invention.
Description of reference numerals: 1-motor switch, 2-snag clamping switch, 3-battery, the snag of 4-multilayer; 5-clamps door, 6-wiping board, 7-tumbler.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
First see Fig. 1 and Fig. 2, Fig. 1 illustrates the front view of whiteboard eraser of the present invention, and Fig. 2 illustrates the side view of whiteboard eraser of the present invention.As can be seen from the figure, this whiteboard eraser of the present invention mainly comprises wiping board 6, multilayer snag 4, clamping door 5, and multilayer snag 4 and clamping door 5 are connected on wiping board 6 by tumbler 7, and multilayer snag 4 forms bulge-structure in the front of wiping board 6.The back side of wiping board 6 is provided with battery case, battery 3 is housed in battery case, battery 3 may be used for the electric cleaning that this electric whiteboard is wiped, also can be used for the clamping clamping door 5, therefore, it is provided with two switches, and one is the motor switch 1 realizing electric cleaning, and another is the snag clamping switch 2 realizing clamping snag.
Preferably, this electric whiteboard is wiped and is of a size of 12.8*7*6.2cm, wiping board 6 adopts ABS engineering plastics, and wiping effect is even, sturdy and durable, and save time, laborsaving, snag anticreep design prevents hand of making dirty, visual effect is good.
One embodiment of the present of invention:
This whiteboard eraser of the present invention, when wiping, provides power supply by battery 3, drives multilayer snag 4 to carry out wiping by motor switch 1.When loosening appears in multilayer snag 4, control biparting clamping door 5 by snag clamping switch 2 and snag is clamped.When multilayer snag 4 changed by needs, also control clamping door 5 by snag clamping switch 2 and unclamp, thus replacing is taken off in multilayer snag 4.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, anyly do not depart from technical solution of the present invention content, the any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
Claims (5)
1. the method that comes off of the anti-snag of whiteboard eraser, it is characterized in that: it clamps snag by arranging two fans by the clamping door of Electronic control, opened the elasticity controlling clamping door clamping snag by snag clamping switch simultaneously, thus the object that realization prevents snag from coming off.
