Description

Dusting blackboard eraser

The utility model belongs to teaching aid, is specifically related to a kind of ash-collecting blackboard eraser.

At present, the blackboard eraser of school in use, dust rises from all around, pollution clothes not only, main is, relates to and dyes environment, directly influences the healthy of teachers and students.

The purpose of this utility model is that a kind of ash-collecting blackboard eraser of avoiding dust pollution is provided.

The utility model is a be fastened end of on box body dust storage chamber of the blackboard wiping board that will be provided with air suction opening, at the box body other end lid that is provided with air outlet that is being fastened, in box body, be provided with battery, micro-machine placed cavity, battery, micro-machine and the switch that is located at outside the box body adopt flexible cord to be connected to each other, on the small electrical arbor, be fixed with impeller, impeller is in the air suction inlet position, be fixed with the dust-separation pad in this corresponding position, position, blackboard wiping board and blackboard eraser face are fixed as one, and make air suction opening corresponding with the wiping face.

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is a front view of the present utility model.

Fig. 2 is the vertical view after Fig. 1 dissects along A-A.

Fig. 3 is a circuit diagram of the present utility model.

As Fig. 1,2, shown in 3, the blackboard wiping board 2 that the utility model will be provided with air suction opening 5 is fastened an end of dust storage chamber 14 is arranged on box body 1, be fastened one at box body 1 other end and be provided with the lid 3 of air outlet 4, in box body 1, be provided with battery 11, micro-machine 8 placed cavities, battery 11, micro-machine 8 and the switch 10 that is located at outside the box body 1 adopt flexible cords to be connected to each other, on 8 of micro-machines, be fixed with impeller 9, impeller 9 is in air suction inlet 12 positions, be fixed with dust-separation pad 13 in this corresponding position, position, blackboard wiping board 2 is fixed as one with blackboard eraser face 6, and makes air suction opening 5 corresponding with wiping face 7.More than said dust-separation pad 13 can select materials such as gauze or sponge for use and adopt gluing or screw is fixed, blackboard eraser face 6 can be selected for use sponge or corduroy etc. to be suitable for the material of blackboard wiping and adopt gluing or screw is fixed on the blackboard wiping board 2.The utility model integral body box body 1 that is rectangle certainly, also can be square.The power line that the utility model adopts is selected flexible cord for use, and micro-machine adopts battery 11 power supplies.

The utility model in use, with 10 groups on switch or by to the position of opening, use battery 11 to connect by the circuit of flexible cord and micro-machine 8, at this moment, micro-machine 8 impeller 9 are the suction shape at air suction inlet 12 and rotate at a high speed, make dust by wiping face 7 and air suction opening 5 suction dust storage chambers 14, discharge through air outlet 4 by the air that dust-separation pad 13 purifies.Finish using, blackboard wiping board 2 is taken off the dust that can clear up in the dust storage chamber 14 from box body 1, also lid 3 can be taken off easy access micro-machine 8 simultaneously or change battery 11.

The utility model is because the ash-collecting blackboard eraser that has adopted the parts such as micro-machine, impeller, air suction opening, wiping face, dust-separation pad, dust storage chamber to form; cause the utility model to be compared with existing blackboard eraser; have when erasing the board; avoid dust pollution, protected teachers and students' the advantage such as healthy. The utility model is simple in structure, and is easy to implement.
