Description
Technical field
The present invention relates to teaching specific purpose tool technical field, specially a kind of teaching Special dust sucking formula erasers.
Background technology
From small to large, the study career that we pass by very long all the way along with blackboard always, but allow student and teacher one
The something directly perplexed is to generate many dust pollutions during chalkboard eraser blackboard wiping.Especially when erasing the board, powder
Ash is easy to drift so that the student and teacher to erase the board very feels bad.
And chalk dust is quite serious to the harm of human body:(1) harm of the dust to teachers and students' body, with the most commonly seen powder of lung
Ash is inhaled into after lung, and majority is delayed in alveolar, and lung damage, pulmonary ventilation are caused by series of chemical effect
Function reduction;(2) at present among the ingredient of market chalk, the content of cadmium metal is higher, and after cadmium is sucked by human body, major storage exists
Apparent to these histologic lesions in liver, kidney bone tissue, major lesions caused by Long Term Contact cadmium compound are pulmonary emphysema and kidney damage
Evil.Cadmium is also one of the metallic element for most easily leading to cancer simultaneously.
Successively all there are many solutions to propose for existing market:For example write on special blackboard using ink pens, make
With dust-free chalk etc..Two schemes drawback is it is clear that the former ink pens price is higher with respect to chalk, and writing is unclear
It is clear, effect of attending class is influenced, and dust-free chalk is not avoided that generation dust, dust suction chalk also occur much more or less, but
It is some effect unobvious of these dust suction chalks, some are expensive, some devices are fine, it is often necessary to repair, practical value
It is low.、
The eraser with means for absorbing chalk dust that many eraser with means for absorbing chalk dust also meet the tendency of, but are widely used at present at present, there is also
Major defect is mainly reflected in the following aspects:
(1) pick-up performance of unregulated power chalkboard eraser is poor, often generates blocking, needs often to repair, use value is low;
(2) dust-absorption cushion does not have cleaning plant, and after leading to long-time use, dust-absorption cushion is easy to happen dust suction blocking, uses the longevity
It orders low, and influences pick-up performance.
