Description
technical fieldthe utility model belongs to classroom apparatus technical field, relates to a kind of electric dust-absorbing blackboard eraser device.
background technologythe structure of prior art blackboard eraser comprises an oval or rectangular base, and described base is provided with the wiping thing that the vestige of letter written with chalk on blackboard can be removed by hairbrush or sponge etc., and the blackboard eraser of this structure facilitates durable, has use in the school of China various places.But also there are some drawbacks, the chalk powder rubbed dances in the air all over the sky, the physical and mental health of serious harm student; Erasing the board is that classmate by duty for the day completed in break, and break allows classmate be used for having a rest, going to toilet, and the classmate erased the board can not get having a rest and has a strong impact on the efficiency of next class; For at primary school or shorter classmate, also need to step on stool when wiping eminence, dangerous property.
summary of the inventionthe purpose of this utility model solves prior art and there is chalk powder health risk when erasing the board, affect the technical problem that student has a rest, danger is high, provides a kind of electric dust-absorbing blackboard eraser device, to overcome the deficiencies in the prior art.
To achieve these goals, a kind of electric dust-absorbing blackboard eraser device of the utility model, it comprises blackboard and is close to the box groove of blackboard; Its main points are that the left and right sides of described blackboard is provided with travel switch, and upper and lower both sides are respectively equipped with slide rail and glidepath; Described upper slide rail is spline-simulating; Described box groove is in " Contraband " font, and inside is provided with the rotating shaft being wound around hairbrush; The upper end of described rotating shaft is provided with angular wheel; The upper end of described box groove is provided with air inlet, is provided with motor above; The power transmission shaft of described motor is provided with successively with the intermeshing angular wheel of described rotating shaft upper end angular wheel and with upper slide rail tooth bar pitch wheel; Lower end and the glidepath of described box groove are slidably connected, and are connected with holding box below by dropping channel; Described dropping channel is provided with blast pipe; Screen pack and air-introduced machine is provided with in described blast pipe; The two ends up and down of described rotating shaft are connected with box groove inwall by bearing block.
It is in parallel with motor wire that box cell wall is close to by the wire of described air-introduced machine, and motor and air-introduced machine are started simultaneously.
Described box groove and blackboard contact site are provided with sealing joint strip, prevent from raising outside chalk powder.
The utility model reasonable in design, easy to use, power is provided by motor, the chalk powder that hairbrush brushes off concentrates in holding box, efficiently solves to there is chalk powder health risk time prior art erases the board, affect that student has a rest, dangerous high technical problem.
accompanying drawing explanationfig. 1 is the utility model structural representation front view;
Fig. 2 is the left TV structure schematic diagram of Fig. 1.
In figure 1, motor 2, air inlet 3, box groove 4, blackboard 5, glidepath 6, dropping channel 7, air-introduced machine 8, screen pack 9, holding box 10, travel switch 11, upper slide rail 12, gear 13, hairbrush 14, angular wheel 15, rotating shaft
detailed description of the inventionaccording to Fig. 1 and Fig. 2, a kind of electric dust-absorbing blackboard eraser device of the utility model, it comprises blackboard 4 and is close to the box groove 3 of blackboard 4; The left and right sides of described blackboard 4 is provided with travel switch 10, and upper and lower both sides are respectively equipped with slide rail 11 and glidepath 5; Described upper slide rail is spline-simulating; Described box groove is in " Contraband " font, and inside is provided with the rotating shaft 15 being wound around hairbrush; The upper end of described rotating shaft 15 is provided with angular wheel; The upper end of described box groove is provided with air inlet 2, is provided with motor 1 above; The power transmission shaft of described motor 1 is provided with successively with the intermeshing angular wheel of described rotating shaft upper end angular wheel 14 and with upper slide rail tooth bar pitch wheel 12; Lower end and the glidepath 5 of described box groove 3 are slidably connected, and are connected with holding box 9 below by dropping channel 6; Described dropping channel 6 is provided with blast pipe; Screen pack 8 and air-introduced machine 7 is provided with in described blast pipe; The two ends up and down of described rotating shaft 15 are connected with box groove inwall by bearing block; It is in parallel with motor wire that box cell wall is close to by the wire of described air-introduced machine 7; Described box groove 3 is provided with sealing joint strip with blackboard 4 contact site.
During use, power-on switch, motor and air-introduced machine start simultaneously, the gear be connected with motor is walked on the tooth bar of upper slide rail, drive motor is walked together with box groove, and angular wheel drives axis of rotation, and the hairbrush in rotating shaft is by under letter written with chalk brush, chalk powder moves downward along box groove inwall along air-flow under the drive of air-introduced machine, finally falls into holding box.Touch travel switch when box groove moves to blackboard opposite side edge, motor reversal, run in opposite direction and again wipe a blackboard, box groove returns the motion of rear touching travel switch to be stopped.The utility model is positioned at blackboard one lateral edges at ordinary times, can not take blackboard space, periodic cleaning holding box, efficiently solves to there is chalk powder health risk when prior art erases the board, affect that student has a rest, dangerous high technical problem.
