Description
(1) technical field:
The utility model relates to dust-proof blackboard eraser, divides by International Patent Classification (IPC) (IPC) to belong to operation; Department of Transportation, printing branch is write or plotter; The big class of office appliance is write or the drawing article group, the device technical group field of the cleaning of blackboard or slabstone.
(2) background technology:
At present, the technology about the device group of the cleaning of blackboard or slabstone existing and that once had was all done very fruitful effort to the demand of dust-proof blackboard eraser, also once designed many outstanding technical schemes.Declare as being kindly helped secure the success of by car of the Decree of Patent Office of China in 1996, Granted publication is CN2219799Y, and China Patent No. (ZL) is: No. 95230044.3 utility model patent title is the utility model patent of " dust absorption blackboard eraser ", the technical scheme that is adopted.Technical elements in the device group of the cleaning of blackboard or slabstone is a routine of great value invention, and it has solved the technical problem of blackboard eraser dust suction effectively.But still have some deficits, it also is difficult to solve the too big technical problem of dust when erasing the board.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of dust-proof blackboard eraser.The too big technical problem of dust when erasing the board with solution.
The dust-proof blackboard eraser that the new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is achieved in that this utility model mainly by: plank, box, Small-sized suction cleaner, big screw, Screw, brush, lead, press button constitute.Its major part Small-sized suction cleaner, big screw, Screw, lead, press button are selected for use by market.Its plank is a rectangular shape, is material with timber, through the machining manufacturing.Its box is a rectangular shape, is material with the iron sheet, through the machining manufacturing.Its brush is a bar shape, is material with useless cloth, through manual bind processing and manufacturing.
In shape, structure and combination thereof, the total essential features of dust-proof blackboard eraser of the present utility model and immediate prior art is: the tip position of box is installed in the position of the bottom of this plate with big screw, the bonding position that is installed in the top of brush of the bottom position of box, be combined into the syndeton of Brush Shapes, function has been the effect that plank, box, brush are fused.The bonding position that is installed in the bottom of box of the tip position of brush is combined into the syndeton of cube shaped, and function has been the effect that erases the board.In shape, structure and combination thereof, the dust-proof blackboard eraser of the present utility model technical characterictic different with immediate prior art is: the tip position of Small-sized suction cleaner is installed in the position of the bottom of plank with Screw, the bottom position of Small-sized suction cleaner hangs the position at the middle part that is installed in box, be combined into the syndeton of " recessed " word shape, function has been to absorb the effect of dust to box.One end position welded and installed of lead is in the position of the inside of Small-sized suction cleaner, the other end position welded and installed of lead is in the position of the bottom of press button, be combined into the syndeton of circuitry shapes, function has been to connect press button and lead, makes the logical effect of circuit.The tip position of box is installed in the position of the bottom of plank with big screw, and the bonding position that is installed in the top of brush of the bottom position of box is combined into the syndeton of blackboard eraser shape, and function has been the effect of the dust that absorbs of dress dust catcher.So just realized that dust-proof blackboard eraser of the present utility model solves the purpose of the technical problem that dust is too big when erasing the board.
The beneficial effect of the dust-proof blackboard eraser of utility model is that to be the solution technical scheme that technical problem adopted that dust is too big when erasing the board compared three place's advantage and improvement with existing with the technology about the device group of the cleaning of blackboard or slabstone that once had to the utility model:
First, because the tip position that has designed Small-sized suction cleaner in the technical scheme of dust-proof blackboard eraser of the present utility model is installed in the position of the bottom of plank with Screw, the bottom position of Small-sized suction cleaner hangs the position at the middle part that is installed in box, be combined into the syndeton of " recessed " word shape, so easier solution absorbs the technical problem of dust to box.
Second, owing to designed the position of an end position welded and installed of lead in the technical scheme of dust-proof blackboard eraser of the present utility model in the inside of Small-sized suction cleaner, the other end position welded and installed of lead is in the position of the bottom of press button, be combined into the syndeton of circuitry shapes, so easier solution connects press button and lead, make the logical technical problem of circuit.
The 3rd, because the tip position that has designed box in the technical scheme of dust-proof blackboard eraser of the present utility model is installed in the position of the bottom of plank with big screw, the bonding position that is installed in the top of brush of the bottom position of box, be combined into the syndeton of blackboard eraser shape, so the technical problem of the dust that easier solution dress dust catcher absorbs.
