Abstract

The utility model discloses a dust suction blackboard eraser which solves the problems of small dust removal area, environment pollution of dust, high labor intensity and the like of the existing blackboard eraser. The dust suction blackboard eraser is characterized in that a brush body (1) takes a shape of square strip; the width of the both ends of the brush body (1) is equal to that of the blackboard; the middle part of the brush body is provided with an inserted connecting port (3); a box (2) in which a miniature dust collector and a battery are arranged and a dust storage box (4) are arranged in the middle of the brush body; both ends of the brush body are provided with sliding chain wheels; and the sliding chain wheels are arranged in tracks on both sides of the blackboard, are matched with pulley blocks (5) arranged at the top end of the blackboard by chains and are controlled by electric power or a hand line (9). The dust suction blackboard eraser has the advantages of simple structure, large clearing area, good erasing effect and basically no dust and can be widely applied to classroom teaching in the school.

Description

Intelligent blackboard is wiped

One, technical field

The utility model belongs to realia, relates in particular to a kind of intelligent blackboard and wipes.

Two, background technology

In daily teaching and work, traditional blackboard eraser wiping area is little, and great majority all are to take artificial erasing, and teacher and classmates make chalk dust fly upward when erasing the board easily, so just cause dust pollution, have a strong impact on the healthy of teacher and classmates.The patent report of relevant blackboard eraser is very many, but still there is the structure more complicated in its major part, and the effect of removing chalk dust is still not obvious, and defective face such as erasing is difficult to be promoted smoothly automatically.

Main purpose of the present utility model is that a kind of simple to operate, wiping area is big, the intelligent blackboard of environmentally-friendly sanitary is wiped for market provides.Main technical schemes is: be provided with above the blackboard in being arranged at the classroom on the body of wall one with the wide strip blackboard eraser of blackboard, the centre of described brush body is provided with the plug-in type connector, its one side that bristle is installed is over against blackboard, face is provided with box and the dust-collecting box that micro-cleaner and battery are installed in addition, its two ends are provided with the slip sprocket wheel and place in the track that is installed on the blackboard both sides, match by chain with the assembly pulley that is placed in the blackboard top, the normal off-position of blackboard brush is put and also is provided with the scrubbing brush sliding tray above a side of blackboard simultaneously, described assembly pulley is both by the motor transmission, control by the switch that is arranged on the body of wall, also can carry out transmission by the rope that pulls that is arranged at assembly pulley.

The beneficial effects of the utility model are: not only simple in structure, easy to use, with low cost, and can carry out automatic or manual erasing blackboard, simultaneously chalk dust is sucked in the wiping board dust-collecting box and concentrate, both reduced the labour intensity of teacher or classmates' blackboard wiping, and also avoided chalk dust to fly upward everywhere and caused environmental pollution.

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

Four, description of drawings

Fig. 1 is the utility model structural representation.

Among the figure, 1 is brush body, and 2 is box, and 3 is connector, and 4 is dust-collecting box, and 5 is assembly pulley, and 6 is sliding tray, and 7 is switch, and 8 is bristle, and 9 for pulling rope.

Five, specific embodiments

As shown in Figure 1, select for use metal material to make the track on blackboard both sides, and blackboard eraser brush body 1, brush body 1 be with body of wall on the wide strip of blackboard, and be provided with plug-in type connector 3 in the centre, bristle 8 is planted in the front of two sections brush bodies 1, and the box 2 and the dust-collecting box 4 of an arrangement dust catcher and battery are set at its back side, and two ends are equipped with the slip sprocket wheel and place in the track of both sides.Be provided with assembly pulley 5 above blackboard, match by the sprocket wheel of chain with brush body 1 two ends, described assembly pulley 5 is controlled by the switch 7 that is arranged on the body of wall by electric-motor drive, also is provided with simultaneously to pull rope 9 and manually control on assembly pulley 5.The normal off-position of blackboard brush is put and also is provided with scrubbing brush sliding tray 6 above a side of blackboard, makes brush body 1 reach two sections brush bodies in can spurring about it and connects or separate.When implementing the utility model, press power switch 7 and connect power supply, assembly pulley 5 rotates under the drive of motor blackboard eraser is moved up and down, open the dust catcher switch simultaneously, the chalk powder of bristle 8 under smearing on blackboard sucked in the dust-collecting box 4, can reach the writing of in erasing blackboard process, both having removed on the blackboard, guarantee the sanitation and hygiene in classroom again.The utility model when the letter written with chalk that need the office of wiping produces, just the blackboard eraser brush body 1 of a side can be drawn inside and outside sliding tray 6 make in the middle of the plug-in type connector disconnect, blackboard eraser is divided into two, wipe unwanted part; During writing on needing the full scale clearance blackboard, make the brush body 1 of a side be reset to blackboard eraser and form an integral body, turn on the power switch 7, blackboard eraser is swept and descend, remove the letter written with chalk on the blackboard from sliding tray 6 places.
