Description
Technical Field
The utility model relates to a blackboard eraser, specifically speaking can be effectual an environmental protection dustless ash handling equipment of reduction dust.
Background
According to the difference of the application, the blackboard eraser can be divided into the following eraser types, namely the traditional eraser type and the eraser type which is made of white board and water. The blackboard eraser is classified according to the material, and the blackboard eraser is made of wood, metal and other materials. The traditional blackboard eraser generates dust which is harmful to human bodies, the dust is not processed in time and is scattered everywhere and easy to be inhaled by the human bodies. The chalk dust and various dusts on the blackboard cause that many students and teachers suffer from diseases such as nose, pharyngitis and the like. At present, the market combines the four functions of dust removal, dust collection and dust removal, and a few blackboard erasers have to be upgraded. Therefore, the project still has great development prospect and great application market demand.
Disclosure of Invention
The utility model provides a dustless ash handling equipment of environmental protection, the operator opens start button earlier before the operation, and the start-up that accompanies strong magnetism DC5V precision micro motor drives the flabellum rotation, and the dust on the blackboard will get into the suction chamber along with the suction of fan, and the operator only needs to slide the blackboard eraser gently just can very easily remove the dust, has changed ordinary blackboard eraser still can not clean up the chalk dust under the condition of using very big strength in the past.
The utility model discloses a lid filter screen, back lid, USB charge interface, starting switch, protecgulum, the technical scheme who adopts lies in: the fan of the environment-friendly dust-free ash removal device is fixedly connected to the main shaft of the strong-magnetic DC5V precision micro motor through a key groove, and the two anti-leakage pieces are fixed on the front cover; the rear cover filter screen is symmetrically fixed on the rear cover, and the USB charging interface and the starting switch are arranged on the side surface of the rear cover; the strong magnetic DC5V precision micro motor is connected to the battery through a wire; the motor shell for the strong magnetic DC5V precision micromotor is fixed on the back cover, and the back cover is fixed with the motor protective cover for the strong magnetic DC5V precision micromotor; the blackboard eraser is fixed on the lower end face of the front cover, and the filter screen of the front cover is fixed on the lower end face of the front cover; the fuel cells are linearly arranged and fixed in the cell shell, and the periphery of the fuel cells is fixed by the cell protective cover.
The technical scheme comprises the following steps: the fuel cells are linearly arranged and fixed in the cell shell, and the periphery of the cells is fixed by a cell protective cover.
The strong magnetic DC5V precision micro motor and the fan rotate, dust around the eraser can be sucked into the dust box by utilizing the duckbill type suction port, the circuit discharges a certain amount of air through the exhaust port to form internal and external pressure difference, and then the dust at the suction port is sucked by centripetal force.
The leakage-proof piece can ensure that dust can not pass through and can ensure smooth air circulation due to the clearance of the leakage-proof piece.
Compared with the prior art, the utility model, following advantage effect has: (1) the absorption amount of the chalk dust by students and teachers is reduced; (2) the appearance of the blackboard eraser is that the device is fixed on the back of the existing blackboard eraser in a buckling mode, so that the device is convenient to disassemble and clean; (3) the device has simple structure and is convenient to carry; (4) besides teaching application, the cleaning tool can also be used for cleaning places which cannot be reached by people.
