Description
(1) technical field:
The utility model relates to novel blackboard eraser, divides by International Patent Classification (IPC) (IPC) to belong to operation, Department of Transportation, and printing branch is write or drawing appliance; The big class of office appliance is write or drawing article; The assistant product group of writing or draw, big group of the cleaning device of blackboard or slabstone has the technical field of the group of sucking chalk powder device.
(2) background technology:
At present, have now and big group of the cleaning device that once had, have the technology of the group of sucking chalk powder device that the demand of novel blackboard eraser was all done very fruitful effort, also once designed many outstanding technical schemes about blackboard or slabstone.As declaring of the Decree of Patent Office of China in 1996 by Chen Jiqun, Granted publication number is CN2225975Y, China Patent No. (ZL) is: No. 95243406.7 utility model patent title is the utility model patent of " not having electricity health care teaching brush ", the technical scheme that is adopted.Big group of the cleaning device of blackboard or slabstone, the technical elements that the group of sucking chalk powder device is arranged are routine of great value inventions, and it has solved the teaching brush does not effectively have the technical problem that electricity keeps healthy.But still have some deficits, it also is difficult to solve the primary grades classmate and wipes less than blackboard top; That wipes is clean, and chip removal is technical problem easily.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of novel blackboard eraser.Wipe less than blackboard top to solve the primary grades classmate; That wipes is clean, and chip removal is technical problem easily.
The novel 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: connecting tube, spring, dress powder box, floss hole, delivery pipe, frame plate, wiping place, starch absorbing device constitute.Its major part spring, frame plate, connecting tube, floss hole are selected for use by market.Its dress powder box is the square shape, is material with timber, through the planing operation manufacturing.Its starch absorbing device is a rectangular shape, is material with cotton, cloth, through the compression molding processing and manufacturing.Its delivery pipe is elongated side's shape, is material with timber, through the planing operation manufacturing.
In shape, structure and combination thereof, the total essential features of novel blackboard eraser of the present utility model and immediate prior art is: the upper position of frame plate is fixedly connected on the lower position of wiping examination place, the interior location of wiping examination place is fixedly mounted on the lower position of starch absorbing device, be combined into the combining structure of rectangular shape, function has been to wipe the effect that powder is inhaled in examination.The inner side of connecting tube is movably connected in the external position of spring, and the bottom of spring is fixedly mounted on the position of the left end of frame plate, is combined into the handle shape combining structure, and function has been the effect that mobile blackboard is wiped.In shape, structure and combination thereof, the novel blackboard eraser of the present utility model technical characterictic different with immediate prior art is: the lower position of starch absorbing device is fixedly connected on the upper end position of dress powder box, the lower end position of dress powder box is movably connected in the upper end position of floss hole, be combined into the combining structure of ink bottle shape, function has been the effect of inhaling powder dress powder.The lower end position of dress powder box is movably connected in the middle end position of floss hole, and the lower end position of floss hole is movably connected in the upper end position of delivery pipe, is combined into the combining structure of straight formula spade shape, and function has been the effect of row's powder.The solution primary grades classmate who has so just realized novel blackboard eraser of the present utility model wipes less than blackboard top; That wipes is clean, and chip removal is the purpose of technical problem easily.
The beneficial effect of the novel blackboard eraser of utility model is: the utility model is wiped less than blackboard top for solving the primary grades classmate; That wipes is clean, and big group of chip removal technical scheme that technical problem adopted easily and the existing and cleaning device about blackboard or slabstone that once had have the technology of the group of sucking chalk powder device to compare two advantages and improvement:
First, owing to designed the upper end position that the lower position of starch absorbing device is fixedly connected on the dress powder box in the technical scheme of novel blackboard eraser of the present utility model, the lower end position of dress powder box is movably connected in the upper end position of floss hole, be combined into the combining structure of ink bottle shape, so can easier solution inhale the technical problem that powder is adorned powder.
Second, because the lower end position that has designed the dress powder box in the technical scheme of novel blackboard eraser of the present utility model is movably connected in the middle end position of floss hole, the lower end position of floss hole is movably connected in the upper end position of delivery pipe, be combined into the combining structure of straight formula spade shape, thus can be easier the technical problem of solution row powder.
