The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of teaching writing device, comprise blackboard and blackboard eraser, opening up water tank is circumscribed with in the side of described blackboard, described opening and described blackboard eraser match, bottom in described water tank is also provided with heating wire, and the back side of described blackboard is also provided with heating wire.
Further, described water tank bottom is provided with delivery port.
Further, standing groove is provided with in the bottom of described blackboard.
Further, described heating wire has multiple, and is evenly in the back side of described blackboard.
The beneficial effects of the utility model are: a kind of teaching writing device that the utility model provides, and under the prerequisite reducing chalk dust, teaching can be kept to continue to carry out simultaneously, improve efficiency of teaching.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
In accompanying drawing, the list of parts representated by each label is as follows:
1, blackboard, 2, blackboard eraser, 3, water tank, 4, heating wire I, 5, heating wire II, 6, delivery port, 7, standing groove.
Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of teaching writing device, comprise blackboard 1 and blackboard eraser 2, opening up water tank 3 is circumscribed with in the side of described blackboard 1, described opening and described blackboard eraser 2 match, bottom in described water tank 3 is also provided with heating wire I 4, is provided with delivery port 6 bottom described water tank 3, and delivery port 6 is for changing the water in water tank 3.The back side of described blackboard 2 is also provided with heating wire II 5.When teacher writes, blackboard eraser 2 is placed on the opening of water tank 3, due to the cause of heating wire I 4 in water tank 3, water in water tank 3 can produce steam, steam rises and is adsorbed on blackboard eraser 1, and blackboard eraser 1 can be avoided directly to get wet, the phenomenon that blackboard eraser 1 wets excessively.Clean off a blackboard when 1 at needs, by blackboard eraser 2 outwash blackboard 1, because blackboard eraser 2 is that steam is got wet, so the surface of the blackboard 1 nuzzled up can be avoided excessively wet, impact is write.The evaporation of blackboard 1 surface moisture accelerated by heating wire II 5 simultaneously, then can write next plate at once, ensure that teaching continues to carry out.Described heating wire II 5 has multiple, and is evenly in the back side of described blackboard 1, accelerates the evaporation of blackboard 1 surface moisture.
Standing groove 7 is provided with, for placing chalk or other foreign material in the bottom of described blackboard 1.In sum, a kind of teaching writing device that the utility model provides, under the prerequisite reducing chalk dust, can keep teaching to continue to carry out simultaneously, improve efficiency of teaching.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
