Description
Technical field
The utility model relates to a kind of device for blackboard eraser that is used for water-soluble chalk, and it belongs to the teaching aid technical field.
Background technology
The micro-ion of tradition chalk dust has very strong germ adsorption capacity, and chalk dust contains compositions such as heavy metal cadmium, lead, manganese simultaneously.In order to solve the problem that traditional chalk dust flies away, a lot of manufacturers propose dust-free chalk, micronic dust chalk, liquid chalk.Now dust-free chalk of selling on the market or micronic dust chalk adopt and add the method that grease or polyalcohols material are made binder in original chalks, make its proportion bigger, be difficult for dispersing, but actual conditions are unsatisfactory.Chalk write with erase process in can produce a large amount of dust, swim in for a long time aerial, the severe contamination room air.The liquid chalk adopts the design concept of blank pen, adopts independent ink storehouse structure, repeatedly the can ink.Serve as a teacher when using and make it unlatching and provide ink to nib by the spring valve of written transfer function power to ink storehouse.But the liquid chalk needs special-purpose black (green) plate, perhaps pastes special-purpose pad pasting on existing blackboard or green plate surface, need carry out the blackboard transformation, and chalk liquid can shoal very soon through the volatilization writing after writing, and the classmate in recoil often reflection does not see the writing on the blackboard content.The liquid chalk is normally imparted knowledge to students owing to problems affect such as a liquid supply is not smooth usually appear in the writing process in the structural design reason.
A kind of water-soluble chalk of exploitation does not produce dust in use now, just can clean with wet cloth, and thing followed problem is that traditional blackboard eraser has not satisfied instructions for use.
Summary of the invention
In order to solve the problem that above-mentioned prior art exists, the utility model provides a kind of device for blackboard eraser that is used for water-soluble chalk.This device for blackboard eraser aims at wipes the water-soluble chalk design, easy to use, does not produce dust, Environmental Safety.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of device for blackboard eraser that is used for water-soluble chalk mainly comprises a blackboard eraser, and it also comprises a special implement for the blackboard eraser service.Described special implement comprises that a housing, one deposit dirty drawer and a wave heave sponge, deposit dirty drawer is positioned at below, blackboard eraser chamber from the end insertion of the housing of perforate cavity, it is indoor that the wave heave sponge is placed on blackboard eraser, blackboard eraser place the wave heave sponge above; Described housing is provided with a dirt-scraping plate,, is provided with in the bottom of putting dirty groove and makes soiling solution flow into the dirty hole of putting of depositing in the dirty drawer for putting dirty groove in the both sides of dirt-scraping plate.
Described blackboard eraser is provided with the wiper that can take off cleaning.
A described end of depositing dirty drawer is provided with a drawer attacker.
The handgrip of described blackboard eraser is provided with side direction concave arc and end concave arc.
The beneficial effects of the utility model are: this device for blackboard eraser that is used for water-soluble chalk, it mainly comprises a blackboard eraser and the special implement for the blackboard eraser service.Special implement comprises that a housing, one deposit dirty drawer and a wave heave sponge, deposits dirty drawer and inserts from an end of housing, and it is indoor that the wave heave sponge is placed on the blackboard eraser that has water, blackboard eraser place the wave heave sponge above.Moistening blackboard eraser wiper is after use is dirty, and one scrapes on ad hoc dirt-scraping plate, and soiling solution can flow into automatically deposit dirty drawer.This device for blackboard eraser aims at wipes the water-soluble chalk design, easy to use, does not produce dust, Environmental Safety.
