Description
Technical field
The invention belongs to culture and education fixture fields, be specifically related to a kind of high-efficiency cleaning blackboard eraser.
Background technology
Remain employing chalk-writing mode in a lot of middle and primary schools at present to impart knowledge to students, especially in the school of rural area.
Generally after blackboard chalk inputs, the blackboard eraser using rag formula is needed to wipe.But, these wipe work base
Originally it is that student on duty for the day is carried out, and teacher writes and compares firmly sometimes, during erasing chalk writing, wastes time and energy, student's length on duty for the day
Time also can suck substantial amounts of chalk dust before staying in blackboard surface.
Although having occurred in that on market that a lot of form is multiple, can effectively reduce dust produce blackboard eraser, but its
Price costly, and is easily damaged, and is not particularly suited for poverty-stricken area.For this reason, it may be necessary to a kind of use cost is low, can be efficient
Rate is removed chalk writing, is reduced student on duty for the day and erase the board the blackboard eraser of durable practicality of time.
Summary of the invention
Present invention aims to the deficiency that prior art exists, it is provided that a kind of simple in construction, use cost be low,
Durable, practical, student on duty for the day can be reduced erase the board the high-efficiency cleaning blackboard eraser of time.
To achieve these goals, present invention employs techniques below scheme:
A kind of high-efficiency cleaning blackboard eraser, including blackboard eraser main body and rag；Described rag is arranged on the middle position of blackboard eraser main body,
And on the edge of the blackboard eraser main body of rag both sides, it is respectively equipped with row's clumps of bristles；The end face of described clumps of bristles is than fixing peace
The end face of the rag installed exceeds 1～2mm.
The present invention further illustrates, and leading flank and trailing flank in blackboard eraser main body are respectively provided with and grip blackboard eraser main body
Groove.Groove is set, facilitates student on duty for the day to grip blackboard eraser, and the fingernail avoiding student on duty for the day rubs with blackboard
Phenomenon, protects the finger of student on duty for the day.
The present invention further illustrates, and described clumps of bristles uses animal hard hair or plastic material to copy hair and make.
In the present invention, two row's clumps of bristles, and the end of clumps of bristles it are additionally arranged at the edge of traditional rag formula blackboard eraser
Face outline is higher than the end face of rag, so when erasing chalk writing, is first contacted with chalk writing by clumps of bristles, and rub letter written with chalk
Mark, is made chalk dust loosen, then is wiped by rag, and the most disposably nuzzling up just can be by clean for chalk writing erasing, and save time province
Power, cleaning efficiency is high.In order to avoid chalk dust too much produces, some water can be sprayed on blackboard and just may be used before erasing the board
With.
Advantages of the present invention:
Simple in construction, use cost are low, cleaning effect good, efficiency is high, time saving and energy saving, it is possible to reduce student on duty for the day when erasing the board
Between, also avoid student on duty for the day and be in for a long time in dust atmosphere.
