The utility model discloses a set up water storage device in the blackboard eraser main part, erase the chalk on the blackboard, through setting up drainage board and water absorption device, prevent that the blackboard eraser main part from leaking, through set up short spring between pressurized -water board and blackboard eraser main part, cause the waste of water storage device water resource when preventing not use, adopt the sponge as water storage device and water absorption device, simple structure, it is with low costs.
Description
Technical field
The utility model relates to realia field, is specifically related to a kind of blackboard blackboard eraser.
Background technology
In use, the chalk dust of teaching flies upward blackboard eraser everywhere, and teachers and students are easily subject to the puzzlement of chalk dust, and the time has been grown, and affect the healthy of teachers and students.And blackboard eraser generally needs to wipe blackboard manually, not only can cause dust from flying, and consuming time.
The water-soluble chalk of current use, avoids the phenomenon of dust from flying, but erasing work is pretty troublesome, has great inconvenience especially in water re-using, needs constantly to add water on the one hand, easily produces on the other hand and leaks, affect the clean of blackboard.
Utility model content
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of blackboard blackboard eraser.
The technical solution adopted in the utility model is: a kind of blackboard blackboard eraser, comprise: blackboard eraser main body, the side of described blackboard eraser main body arranges water filling II, described blackboard eraser body interior is water storage device, the top of described water storage device arranges water squeezing plate, the below of described water storage device arranges water filter plate, and the below of described water filter plate arranges water absorber, and described blackboard eraser main body also arranges handle.
Further, described water squeezing plate also arranges short spring, water squeezing plate is fixedly connected with described blackboard eraser main body by short spring.
Further, described water storage device and water absorber are sponge.
Further, described water filling II place arranges gas thread.Can be connected with outer water tube by arranging gas thread, easy to use.
Further, described blackboard eraser main body and handle junction arrange elastic tape.
Further, described water filter plate is double-deck water filter plate, arranges and be spaced apart 2mm between two-layer water filter plate.
The beneficial effects of the utility model are: the utility model by arranging water storage device in blackboard eraser main body, when using blackboard eraser, the stressed rear generation pressure of handle part, by water squeezing plate, water storage device is extruded, water is contacted with blackboard, chalk on blackboard being wiped, by arranging water filter plate and water absorber, preventing blackboard eraser main body from leaking; By arranging short spring between water squeezing plate and blackboard eraser main body, when not using, blackboard blackboard eraser vertically can be placed, now water squeezing plate lifts by short spring, water squeezing plate can not extrude water storage device, cause the waste of water storage device water resource when preventing from not using; Adopt sponge as water storage device and water absorber, structure is simple, and cost is low, easy for installation; Can be connected with outer water tube by arranging gas thread, easy to use; Water filter plate adopts double-decker, effectively can carry out filter moisture to raclementum, be absorbed, prevent from occurring water leakage situation in erase process by the moisture of water absorber to filtering of below, and erasing effect is clean.
Accompanying drawing explanation
Fig. 1 is a kind of blackboard blackboard eraser front view that the utility model proposes;
Fig. 2 is a kind of blackboard blackboard eraser top view that the utility model proposes.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further detailed.
See Fig. 1 and Fig. 2, wherein Fig. 1 is a kind of blackboard blackboard eraser front view that the utility model proposes; Fig. 2 is a kind of blackboard blackboard eraser top view that the utility model proposes.
As depicted in figs. 1 and 2, a kind of blackboard blackboard eraser, comprise: blackboard eraser main body 1, the side of described blackboard eraser main body 1 arranges water filling port 2, described blackboard eraser main body 1 inside is water storage device 3, and the top of described water storage device 3 arranges water squeezing plate 4, and the below of described water storage device 3 arranges water filter plate 6, the below of described water filter plate 6 arranges water absorber 7, and described blackboard eraser main body 1 also arranges handle 8.
In the utility model embodiment, by arranging water storage device in blackboard eraser main body, when using blackboard eraser, the stressed rear generation pressure of handle part, by water squeezing plate, water storage device is extruded, water is contacted with blackboard, the chalk on blackboard is wiped, by arranging water filter plate and water absorber, prevent blackboard eraser main body from leaking.
Further, described water squeezing plate 4 also arranges short spring 5, water squeezing plate 4 is fixedly connected with described blackboard eraser main body 1 by short spring 5.
In the utility model embodiment, by arranging short spring between water squeezing plate and blackboard eraser main body, when not using, blackboard blackboard eraser vertically can be placed, now water squeezing plate lifts by short spring, water squeezing plate can not extrude water storage device, cause the waste of water storage device water resource when preventing from not using.
Further, described water storage device 3 and water absorber 7 are sponge.
In the utility model embodiment, adopt sponge as water storage device and water absorber, structure is simple, and cost is low, easy for installation.
Further, described water filling port 2 place arranges gas thread.Can be connected with outer water tube by arranging gas thread, easy to use.
Further, described blackboard eraser main body 1 arranges elastic tape 9 with handle 8 junction.Be connected and sealed by elastic tape and blackboard eraser main body.
Further, described water filter plate 6 is double-deck water filter plate, arranges and be spaced apart 2mm between two-layer water filter plate.
In the utility model embodiment, water filter plate adopts double-decker, effectively can carry out filter moisture to raclementum, be absorbed, prevent from occurring water leakage situation in erase process by the moisture of water absorber to filtering of below, and erasing effect is clean.
Above by reference to the accompanying drawings detailed inadequate explanation is done to the utility model preferred embodiment, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from the utility model aim.Do not depart from design of the present utility model and scope can make many other and change and remodeling.Should be appreciated that the utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
