(3) summary of the invention:
The purpose of this utility model is to provide a kind of dust absorption blackboard eraser.To solve the convenient dust of inhaling; Store the technical problem of dust.
The new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is: the utility model dust absorption blackboard eraser, main blackboard eraser backboard, skylight, dividing plate, piston, base plate, powder feeding band, dust catcher, switch, power supply, suction powder hole, blackboard wiper, lead constitute.Its major part piston, powder feeding band, dust catcher, switch, power supply, blackboard wiper, lead are selected for use by market.Its blackboard eraser backboard is a rectangular shape, is material with plastics, through the machined manufacturing.Its skylight, dividing plate, base plate are elongate in shape, are material with plastics, through the machined manufacturing.
In shape, structure and combination thereof, the total essential features of dust absorption blackboard eraser of the present utility model and immediate prior art is: the integral position of blackboard wiper is fixedly mounted on the lower end of blackboard eraser backboard, be combined into the integrative-structure of blackboard eraser shape, function has been the effect of blackboard eraser.In shape, structure and in conjunction with last, the dust absorption blackboard eraser of the present utility model technical characterictic different with immediate prior art is: hollow shape is processed into mechanical means in the centre position of blackboard eraser panel, and above the blackboard eraser backboard, process a cavity and the integral body in skylight is installed, the dust catcher overall structure is fixedly mounted on the upper surface of base plate of the inside of blackboard eraser backboard, and be installed in the floor on power supply be installed in blackboard eraser behind the switch in the plate outside link to each other, constitute the closed-loop path, the lower plate of base plate processes with mechanical means inhales the powder hole, being convenient to dust sucks, be combined into the combining structure of blackboard eraser shape, function has been the effect that makes things convenient for dust suction.The bosom position of blackboard eraser backboard is divided into two parts with dividing plate, need not lead tube cell dust catcher and the flour opening of depositing powder box are sealed with piston, is combined into formless combining structure, and function has been the effect that stores dust.So just reached the convenient dust of inhaling of dust absorption blackboard eraser of the present utility model; Store the purpose of dust.
The beneficial effect of the dust absorption blackboard eraser of utility model is that the utility model is to solve the convenient dust of inhaling; The technical scheme that technical problem adopted that stores dust has been compared two place's advantage and improvement with existing with the technology about the cleaning device group of blackboard or slabstone that once had:
First, be processed into hollow shape owing to designed the centre position of blackboard eraser panel in the technical scheme of dust absorption blackboard eraser of the present utility model with mechanical means, and above the blackboard eraser backboard, process a cavity and the integral body in skylight is installed, the dust catcher overall structure is fixedly mounted on the upper surface of base plate 5 of the inside of blackboard eraser backboard, and be installed in the floor on power supply be installed in blackboard eraser behind the switch in the plate outside link to each other, constitute the closed-loop path, the lower plate of base plate processes with mechanical means inhales the powder hole, be convenient to dust and suck, so the convenient technical problem of inhaling dust of easier solution.
Second, be divided into two parts owing to designed the bosom position of blackboard eraser backboard in the technical scheme of dust absorption blackboard eraser of the present utility model with dividing plate, need not lead tube cell dust catcher and the flour opening of depositing powder box are sealed with piston, so easier solution stores the technical problem of dust.
