Description
Technical field
The utility model relates to a kind of novel blackboard eraser, belongs to realia technical field of structures.
Background technology
The educational aid of indispensability when blackboard eraser is teachers' instruction, existing wiping blackboard structure design is single, the bristle only comprising base and be installed on base, mainly there is following defect in this kind of structure: dust from flying when 1, erasing the board, and affects the healthy of teacher and student; When 2, erasing the board, hold base, comfortable feel is poor; 3, especially mathematics teacher, frequent needs on blackboard large length enumerate some formula or algorithm, when giving lessons, erasing part formula or data may be needed, because area the relative single file formula of existing blackboard eraser bristle is comparatively large, therefore, wiping may cause the formula of other adjacent lines or data to be wiped out, teacher also will continue to supplement, bothers very much.
Summary of the invention
The purpose of this utility model is the weak point solving prior art existence, a kind of smart structural design is provided, comfortable feel during use, can not only absorb the chalk powder produced in blackboard-cleaning process, and nearer formula or data can not wipe the novel blackboard eraser of adjacent lines formula or data by mistake at wiping interval.
The utility model is achieved through the following technical solutions:
A kind of novel blackboard eraser, comprise base 1 and be installed on the bristle 2 below base 1, its special character is that the upper surface of base 1 is connected with cover body 3, cover body 3 comprises two protruding cavity I4 of hump shape separately, protruding cavity II5, connection hand strap 6 for preventing blackboard eraser from dropping when wiping is installed between protruding cavity I4 and protruding cavity II5, base 1 is laid with multiple air-vent 7, place near base 1 in cover body 3 is provided with screen pack 8, fan 9 for dust adsorption is installed in cover body 3, the outside of cover body 3 is provided with the motor 10 for driving fan 9 to work, interlayer I11 is provided with in protruding cavity I4, interlayer I11 is provided with the bristle I12 of rounded arrangement, it is outside that bristle I12 is positioned at protruding cavity I4, interlayer II13 is provided with in protruding cavity II5, interlayer II13 is provided with the bristle II14 of rectangular arrangement, it is outside that bristle II14 is positioned at protruding cavity II5,
In order to make blackboard eraser more comfortable in use, the interval region between described protruding cavity 14 and protruding cavity II5 is provided with sweat absorbing cotton layer of cloth 15;
Described protruding cavity I4 and protruding cavity II5 is all connected with lid.
A kind of novel blackboard eraser of the present utility model, reasonable in design, when erasing the board, starter motor, driven by motor fan work, dust is sucked in cover body by air-vent, effectively prevent dust from wantonly dispersing, after wiping, only cover body need be taken off, pour out dust, during wiping, palm is held in protruding cavity I, between protruding cavity II, the hand strap that is connected again uses, comfort level during use can not only be improved, and can prevent blackboard eraser skidding from flying out, the bristle I of rounded arrangement and the bristle II of rectangular arrangement can use as required, prevent formula or the data of wiping adjacent lines at the nearer formula in wiping interval or data mistiming, in sum, the utility model reasonable in design, easy to use, at teaching field, there is good application prospect.
