Description
Technical field
The utility model relates to a kind of blackboard, is specifically related to a kind of can fast erasing and the new type blackboard of anti-dust.
Background technology
The length and width of the blackboard of teaching are all larger, teacher uses chalk to write above, then blackboard eraser is used to be wiped by letter written with chalk, normally used is all that small blackboard is wiped, erasing is wasted time and energy, wipe more difficult for short student or teacher, and produce a lot of chalk dusts when wiping, it is very unfavorable to health to suck in human body.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of easy to use, can fast wipe and the new type blackboard of anti-dust.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
Fast can wipe and the new type blackboard of anti-dust, comprise blackboard body; The blackboard eraser that can laterally slide is provided with before described blackboard body; Described blackboard eraser is provided with the cavity of hollow, and this cavity is connected with the water bottle being located at blackboard eraser top; Blackboard eraser is just provided with felt to the one side of blackboard body, and this face of blackboard eraser offers multiple aperture leading to cavity, and felt covers on aperture.
Further, described blackboard eraser is just provided with longitudinal two row's felts to the one side of blackboard body, and a row is wherein dry felt, and described aperture is located on the blackboard eraser face that another row's felt covers.
Further, blackboard body is close to by described felt, and the width of the height of felt and blackboard body is basically identical.
Further, the diameter of described cavity is no more than 3mm.
Further, under on blackboard eraser, the diameter of described aperture from large to small.
Further, the bottom of described blackboard eraser is provided with handle.
Further, described water bottle is laterally placed, and its bottleneck is provided with switch, and this switch is connected with handle by the straight-bar of a longitudinal direction, the rotating bottom being located at blackboard eraser of handle.
Further, the both sides up and down of described blackboard body are respectively provided with the slideway of a transverse direction, and the two ends up and down of blackboard eraser are respectively provided with a pulley mated with slideway.
Further, the side, bottom of described blackboard body be provided with can upper and lower 90 degree upset supports.
The beneficial effect adopting technique scheme to produce is:
The utility model can by the letter written with chalk on blackboard disposable erasing clean, to save time and laborsaving, solve the teacher heavy or short teacher of task that erases the board and wipe problem less than place, blackboard top, and occur without dust when wiping, can not be detrimental to health.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, 2, the utility model discloses a kind of can fast erasing and the new type blackboard of anti-dust, comprise blackboard body 1; The blackboard eraser 2 that can laterally slide is provided with before blackboard body 1; Blackboard eraser 2 is provided with the cavity of hollow, and this cavity is connected with the water bottle 8 being located at blackboard eraser 2 top; Blackboard eraser 2 is just provided with felt 7 to the one side of blackboard body 1, and this face of blackboard eraser 2 offers multiple aperture leading to cavity, and felt 7 covers on aperture.Blackboard body 1 is close to by felt 7, and the width of the height of felt 7 and blackboard body 1 is basically identical.Water bottle 8 is for water filling in the cavity to blackboard eraser 2, and water infiltrates felt 7 from aperture, makes felt 7 be wet all the time, and that not only wipes is cleaner, and chalk dust can be adsorbed on felt surface, prevents chalk dust to be detrimental to health.
Further, blackboard eraser 2 is just provided with longitudinal two row's felts 7 to the one side of blackboard body 1, and a row is wherein dry felt, and described aperture is located on the blackboard eraser 2 that another row's felt covers, and namely another row's felt is wet hair felt.Wet hair felt is used for fast by clean for the letter written with chalk erasing in blackboard body 1, and without dust, the washmarking that dry felt is used for when being wiped by wet hair felt absorbs cleanly.
The diameter of cavity is no more than 3mm.This is because water flows in cavity from top to bottom, and because the gravity of water self, as cavity diameter is excessive, easily cause cavity bottom to be full of water and cavity top does not have the situation of water, so just make felt uniform water absorption not soak into, therefore cavity diameter is no more than 3mm, cavity can be made to have water to exist up and down all the time, the moisture that felt even suction is appropriate, thus cleaner during wiping, and wiping complete after can not leave washmarking and affect and write on blackboard.Under on blackboard eraser 2, the diameter of aperture from large to small, is also to make water uniformly penetrating in felt.
The both sides up and down of blackboard body 1 are respectively provided with the slideway 3 of a transverse direction, and the two ends up and down of blackboard eraser 2 are respectively provided with a pulley 4 mated with slideway 3; Water bottle 8 is laterally placed, and its bottleneck is provided with switch, and this switch is connected with handle 6 by the straight-bar of a longitudinal direction, the rotating bottom being located at blackboard eraser 2 of handle 6.When needs erasing chalk word, can first turning handle 6, so straight-bar pulls the switch on bottleneck downwards, water in water bottle 8 can inject cavity, makes felt moistening, then touches handle 6 along blackboard, blackboard eraser 2 is made laterally to slide into the other end from one end of blackboard body 1, the disposable erasing of letter written with chalk in whole blackboard body 1 is clean, to save time and laborsaving, solve the teacher heavy or short teacher of task that erases the board and wipe problem less than place, blackboard top.After clashing, counter-rotation handle 6, the switch of straight-bar upwardly on bottleneck, water bottle 8 is closed, and does not have water and injects cavity.
The side, bottom of blackboard body 1 is provided with can the supports 5 of upper and lower 90 degree of upsets, and support 5 is installed in bottom on the right side of blackboard body 1 by hinge, when not using, support 5 upwards can be overturn and fold up, walk not affect teacher on dais; When it is desired to be used, support 5 is turn to level downwards, support 5 can be placed the thing such as chalk holder and common blackboard eraser, make these objects have fixing deposit position, be unlikely to leave about, can not find when needing.
