Description
Technical field
This utility model relates to a kind of novel blackboard eraser, belongs to teaching aid field.
Background technology
The blackboard eraser of school there is no the function of dust suction at present, blackboard is by after wiping, the dust of substantial amounts of chalk can fall other corners on the person of blackboard wiping or classroom, the most unhygienic teaching environment also having had a strong impact on classroom, and the dust of chalk can affect the healthy of people after being sucked by people, teacher notably suffers from occupation disease due to the long-term dust sucking chalk.
Summary of the invention
This utility model is in order to make up the defect of prior art, it is provided that a kind of novel blackboard eraser.
This utility model is achieved by the following technical solution:
A kind of novel blackboard eraser, including box body and the two pieces of parallel baffles being arranged in box body, this dividing plate is divided into three parts housing hollow, this cavity mid portion be erasing body cavity be the water storage cavity that structure is identical with both sides, it is characterized in that: bottom described dividing plate, leave water channel, the upper end of dividing plate connects the press device being positioned at box body top by a connecting rod, for being flexibly connected between connecting rod with box body, and the lower position at two connecting rod intersection points is fixed with a spring, the lower contact point of spring is on box body outer wall.
Wherein:
Described water storage cavity top also has a circular hole, and circular hole is arranged over block.Described erasing body cavity is used for installing sponge or the fabric such as felt, cloth；In terms of front, the lateral length of this erasing body cavity is more than the lateral length of arbitrary water storage cavity.
The beneficial effects of the utility model are: simple in construction, easy to use；The erasing body of water suction makes dust be unlikely to everywhere to fly upward, and improves teaching environment, protects health；Design ingenious rationally, low cost, it is simple to promote.
