Description
Technical field
A kind of novel blackboard eraser is the utility model is related to, belongs to educational supply field.
Background technology
Blackboard is displaying apparatus important in teacher's teaching process, with society continuous development, although teaching method by

Fly away, this carrys out serious harm to human body health care belt, and the case layer for suffering from breathing problem because sucking chalk dust for a long time goes out not
Thoroughly.Wherein, a major reason for causing dust to fly away is exactly to wipe person's handwriting using dry blackboard eraser.Also have tried to use wet plate
Person's handwriting is wiped, could be used for a moment because the blackboard needs that wet blackboard eraser nuzzles up dry well, so, although being erased the board with wet blackboard eraser
Solve the problems, such as that dust flies away, but also bring inconvenience simultaneously.In order to solve these problems, it is necessary to enter to existing blackboard eraser base
One step is improved.
The content of the invention
The purpose of this utility model is to provide a kind of novel blackboard eraser, it is therefore intended that solving existing blackboard eraser can only xerotripsis
Or wet rubbing blackboard, cause the problem of inconvenient for use.
A kind of novel blackboard eraser, it is convex by fixed body, handle, water storage case, wet rubbing fixed cover, fixed plate, spanner, bias
Edge, pressing water spray switch, spiral cover, fixed cover, wet rubbing, xerotripsis fixed cover, xerotripsis, movable post, spray water belt, docking port, reset bullet
Spring, rotating shaft composition；It is characterized in that the fixed fixed cover of the forward, central part of the fixed body, and it is provided with fixed cover fixed
The wet rubbing fixed cover of wet rubbing；There are two rectangular channels both sides before fixed body, and the xerotripsis that fixed xerotripsis is provided with groove is consolidated
Fixed set；The fixed three movable posts in the back side of the xerotripsis fixed cover, and movable post passes through fixed body, and covered on movable post
Back-moving spring；Handle is installed among the rear portion of the fixed body, handle connects with the water storage case in the middle part of fixed body, and
There is pressing water spray switch on handle；Middle part is transversely mounted a rotating shaft by two fixed plates behind fixed body,
The fixed spanner in middle part of rotating shaft, the fixed eccentric band flange in both sides of rotating shaft, and eccentric band flange and the work in the middle part of xerotripsis fixed cover
End in contact after dynamic post.
There is spiral cover on the water storage case.
There is the spray water belt of connection water storage case in the middle part of the fixed cover, and have docking port and spray water belt pair on wet rubbing fixed cover
Should.
The front end of the back-moving spring is fixed on xerotripsis fixed cover, and rear end is fixed on fixed body.
The wet rubbing fixed cover can take out out of fixed cover, be convenient for changing.
The beneficial effects of the utility model are to devise a kind of novel blackboard eraser, and the blackboard eraser can realize automatic spray
Water, it is easy to wipe chalk writings, prevents dust from flying away, it can in addition contain quickly dry water mark, fast and easy uses blackboard.
In the presence of back-moving spring, xerotripsis fixed cover retraction pushes pressing water spray switch, it is necessary to when erasing the board, and water just penetrates into wet rubbing
On, now after wiping one time, spanner can be pulled upwards, in the presence of eccentric band flange, xerotripsis is solid to wipe person's handwriting with wet rubbing
Fixed set protrudes forward, now can be with xerotripsis quick wipe water mark.The utility model clever structure, it is reasonable in design, using mould
Blockization designs, and makes blackboard eraser while has two kinds of functions of xerotripsis and wet rubbing, is brought convenience to use.
