Abstract
The invention discloses a dust-free eraser, and relates to the technical field of educating instruments. The dust-free eraser comprises a closed lower chamber and an upper chamber connected with the lower chamber. The lower chamber communicates with the upper chamber by virtue of a through hole. A water feeding hole is formed in the lower chamber. A blanking cap is arranged on the water feeding hole. A base is arranged in the upper chamber. Eraser plates are arranged in the base, and extend out of a housing of the upper chamber. A water absorption layer is arranged outside the housing of the upper chamber. Micropores are formed in the water absorption layer and communicate with the upper chamber. Compared with the prior art, the dust-free eraser can solve the problem that at present, too much dust is generated when a blackboard is erased with an eraser.
Description
Technical field
The present invention relates to educate apparatus manufacturing technology field, a kind of blackboard eraser for imparting knowledge to students.
Background technology
In today that computer technology is universal, particularly some middle and primary schools in some schools, teachers still adopt chalk method of writing words on blackboard and impart knowledge to students, it is known that, after chalk is write on blackboard, can fall many chalk dusts with blackboard eraser wiping, chalk dust causes healthy hidden danger to teacher and classmate on duty for the day.
Summary of the invention
It is an object of the invention to provide a kind of Dustless eraser, it can solve the problem that when current blackboard eraser erases the board, dust is big.
In order to solve the problems referred to above, the technical solution used in the present invention is:
This Dustless eraser, including the lower chambers closed and the upper chamber being connected with described lower chambers, described lower chambers is connected with described upper chamber by through hole, and described lower chambers is provided with water inlet, and described water inlet is provided with blanking cover；Being provided with pedestal in described upper chamber, be provided with blackboard eraser sheet in described pedestal, described blackboard eraser sheet stretches out outside described upper chamber housing, and described upper chamber hull outside is provided with water accepting layer；Described water accepting layer is provided with micropore and connects with described upper chamber.
In above technical scheme, further scheme may is that described water accepting layer is made up of sponge, and described water accepting layer surface is provided with a plurality of groove.
Further: described upper chamber housing and water accepting layer are divided into movable part and standing part, and wherein the housing of both sides movable part is by hinge and described lower chambers housing hinge.
Further: described blackboard eraser sheet is connected with described base runner.
Further: described blackboard eraser sheet is fixing with described pedestal to be connected.
Further: described lower chambers housing and described upper chamber housing are made up of plastic material；Described blackboard eraser sheet is made up of elastomeric material.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
1, the present invention is divided into upper and lower two chambers, and wherein lower chambers is water filling chamber, and upper chamber is provided with dismountable movable wiping board, is provided with sponge, is provided with micropore, is provided with through hole between upper and lower chamber between upper chamber and sponge outside it；The water of bottom chamber enters upper chamber by through hole, and enters sponge by micropore；2, the sponge outside upper chamber of the present invention is provided with groove, and chalk dust falls through in groove, can greatly reduce the probability sucked by people when chalk dust drops；3, upper chamber of the present invention is provided with hinge from both sides, makes upper chamber can open to both sides, it is simple to change blackboard eraser sheet.
