Abstract

The utility model discloses a full automatic teaching blackboard wiper. The technical proposal of the utility model is that a rolling brush which has the same height with the blackboard and is contacted with the black board is movably connected with the frame of the normal blackboard through a track and a gear; the rolling brush is correspondingly provided with an outer cover, a dust collecting box and a touch switch; and the rolling brush moves in parallel and rotates to automatically wipe the blackboard and suck dust in effect of a motor and a speed reducer. With the above structure, the utility model has the advantages of automatically wiping the writing on the blackboard conveniently and fast, saving labor and time, no dust pollution and being beneficial for health.

Description

Full-automatic blackboard for education wiper

The utility model is a kind of new-type teaching aid, specifically is meant a kind of " full-automatic blackboard for education wiper ".

For a long time, blackboard, blackboard eraser and chalk are that school teacher gives the student impart knowledge, and the common tool of teaching demonstration content, this apparatus have to write in teaching clearly easily to be recognized, promptly write and promptly wipe convenient and practical characteristics.Yet, at present school's blackboard eraser commonly used is the blackboard eraser of one side box structure villous, and in use there is following shortcoming in this blackboard eraser: (1) when blackboard wiping, dust from flying often, cause a large amount of dusts of the passive breathing of academics and students, the utmost point is unfavorable for physical and mental health; (3) wipe the class period that the examination blackboard will delay many preciousnesses, the muscle power that also consumes teacher; Behind (3) one class, usually cause on teacher's head, on the clothes, be full of dust on the face.For addressing this problem, Patent Office of the People's Republic of China discloses a kind of " dust absorption blackboard eraser ", it is in the inside of blackboard eraser micromachine to be set and dust exhaust apparatus reaches the dust suction effect, its weak point is: (1) is owing to be provided with motor, dust exhaust apparatus battery etc. in blackboard eraser, its volume is inevitable big, deal is heavier, uses effort, poor effect; (2) quality time that still will spend the teacher removes to wipe the examination blackboard, does not save time, and is also not laborsaving.

The purpose of this utility model provides a kind of writing on cleaning off a blackboard automatically quickly and easily, not only saves time but also laborsaving, does not have dust pollution again, is beneficial to the blackboard for education wiper of teachers and students' health.

The purpose of this utility model is achieved in that it is by being movably connected in the roller brush 2 on blackboard 1 frame and being fixedly connected on that roller is brushed motor 3, decelerator 4, the gear 5 on 2 terminations and the outer cover 6, laying dust box 7, the touching switch 8 that are fixed on the roller brush body are formed, it is characterized in that: described roller brush is a length and surperficial and the blackboard surface parallel hollow brush body that contacts identical with the blackboard height, described blackboard frame is provided with the track 9 isometric with frame, and the gear 5 that roller is brushed on 2 terminations flexibly connects by track 9 and blackboard.

Described outer cover 6 is shape and roller brush 2 corresponding housings, leaves the space but outside sealing between this housing and the roller brush, and the outer cover the inside is provided with three dedusting gussets, and bristle and gusset touched when the roller brush rotated, and flicked off dust.The lower end of housing flexibly connects a laying dust box 7, and laying dust box 7 communicates with outer cover.

Described roller brush 2 is hollow cylinders made from timber or plastics, and what its surface planted certain density hunts mane or nylon mane.Roller brush axostylus axostyle upper end flexibly connects with decelerator driving wheel axostylus axostyle lower end; Roller brush rotational velocity is identical with motor speed, about 300-600 rev/min.

Described gear 5 links to each other with the follower axostylus axostyle of decelerator 4, angle is vertical with the roller brush, because the effect of decelerator, when motor and roller brush rotate, gear is covered whole process (about 3 meters) to walk about along track (having tooth bar) than jogging speed (60-180 rev/min) about about 10 seconds.

Described track 9 is made with angle bar or aluminium alloy extrusions, be as the criterion can firmly be installed on blackboard upper and lower side frame or the wall and can bear constant weight, on it rail the inside also must setting-in with walk the tooth bar that moving gear matches, its down rail then need only smooth smooth energy regular and guiding roller two truckles brushing the lower end get final product.

The using method and the course of action of this utility model are as follows:

Press the startup push button, driven by motor decelerator and walking gear rotate simultaneously, and the decelerator driving wheel drives the roller brush and rotates blackboard wiping, and decelerator follower driven gear is steadily walked along tooth bar simultaneously, two trundles in roller brush lower end then roll in lower railway and walk, and cover whole process about ten seconds.In the time of will arriving the blackboard edge, the automatic shutdown on roller brush device top is bumped the little plate washer that button is arranged on the blackboard edge and is depressed, and finishes automatic outage shutdown.No matter left to the right, the user need only click the startup push button gently, and all the other actions are finished automatically, and are easy to operate laborsaving.
