Abstract
An automatic blackboard eraser relates to the field of school things and comprises an outer housing (1), a battery device (2), a motor control device (3), a belt (4), a rotating shaft (5), a circular cylinder shaft (6), a cylindrical erasing cloth (7), a fixed support frame (8), a dustproof board (9) and an erasing switch (10). In the utility model, the motor control device, the circular cylinder shaft, the cylindrical erasing cloth and the dustproof board are added. When the erasing switch is turned on, the motor control device controls the circular cylinder shaft to drive the cylindrical erasing cloth, thus erasing the chalk words on the blackboard, and the dustproof board is adopted to reduce the chalk dust fly; therefore, the utility model saves time and labor, improves the teaching efficiency of the teachers and relatively improves the learning efficiency of the students in the classroom.
Description
Technical field:
The utility model relates to the schooling apparatus field, is specifically related to a kind of automatic blackboard eraser.

In the classroom in the class, the teacher not only wants conscientious preparing lessons, also handlebar prepare lessons in have emphasis at the enterprising andante book of blackboard, at this time, some special exercise question topic types, need classmates in the notes of classroom, to remember, when particularly carrying out senior high school period study, blackboard writing on the blackboard content is always many, the teacher constantly writes some emphasis sentences at that time at school the time in addition, because the writing on the blackboard of blackboard design needs, always will constantly will wipe then, at this moment blackboard eraser has been maximum instrument that the teacher uses, present blackboard eraser is to be provided with cleaning wiping cloth under plastics or the iron sheet outer casing, but the blackboard wiping that always needs the teacher constantly to exert oneself, to reach letter written with chalk on the blackboard is wiped, effort, every class is used in the last time that firmly erases the board with respect to whole class, and the time also is many, reduce the efficient that the teacher gives a lesson, increased the labour intensity that the teacher gives a lesson.The teacher uses the blackboard eraser that uses now on class owing to there is not dust guard in addition, and causes chalk dust to fly upward after wiping the examination blackboard everywhere, just as having descended a white chalk dust-shower, influences teacher classmate's health.
The utility model content:
The purpose of this utility model provides a kind of automatic blackboard eraser, it can solve the existing problem of background technology, it adopts is increasing motor control assembly, circular cylinder axle, tubular wiping examination cloth, dust excluding plate, after opening the wiping switch, then motor control assembly control circular cylinder axle drives tubular and wipes examination cloth, thereby letter written with chalk on the blackboard is wiped out, reducing chalk dust by dust excluding plate flies upward, time saving and energy saving, improved teacher's efficient of giving a lesson, also with respect to improving students classroom learning efficient.
In order to solve the existing problem of background technology, the utility model is that it comprises outer casing 1, cell apparatus 2, motor control assembly 3, belt 4, rotating shaft 5, circular cylinder axle 6, tubular is wiped examination cloth 7, fixing support rack 8, dust excluding plate 9, wipe runin and close 10, cell apparatus 2, motor control assembly 3 is arranged in the outer casing 1, outer casing 1 both sides are provided with fixing support rack 8, circular cylinder axle 6 is passed in rotating shaft 5, belt 4 one ends connect rotating shaft 5, one end is connected on the motor of motor control assembly 3, dust excluding plate 9 is arranged on both sides, outer casing 1 front and back, tubular is wiped examination cloth 7 and is installed on the circular cylinder axle 6, wipes runin pass 10 and is installed in a side on the outer casing 1.It adopts the utility model at increase motor control assembly, circular cylinder axle, tubular wiping examination cloth, dust excluding plate, after opening the wiping switch, then motor control assembly control circular cylinder axle drives tubular and wipes examination cloth, thereby letter written with chalk on the blackboard is wiped out, reducing chalk dust by dust excluding plate flies upward, time saving and energy saving, improved teacher's efficient of giving a lesson, also with respect to improving students classroom learning efficient.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
It comprises outer casing 1 this specific embodiment, cell apparatus 2, motor control assembly 3, belt 4, rotating shaft 5, circular cylinder axle 6, tubular is wiped examination cloth 7, fixing support rack 8, dust excluding plate 9, wipe runin and close 10, cell apparatus 2, motor control assembly 3 is arranged in the outer casing 1, outer casing 1 both sides are provided with fixing support rack 8, circular cylinder axle 6 is passed in rotating shaft 5, belt 4 one ends connect rotating shaft 5, one end is connected on the motor of motor control assembly 3, dust excluding plate 9 is arranged on both sides, outer casing 1 front and back, tubular is wiped examination cloth 7 and is installed on the circular cylinder axle 6, to wipe runin pass 10 and be installed in a side on the outer casing 1. its adopts the utility model at the increase motor control assembly, the circular cylinder axle, tubular is wiped examination cloth, dust excluding plate, after opening the wiping switch, then motor control assembly control circular cylinder axle drives tubular and wipes examination cloth, thereby letter written with chalk on the blackboard is wiped out, reducing chalk dust by dust excluding plate flies upward, time saving and energy saving, improved teacher's efficient of giving a lesson, also with respect to improving students classroom learning efficient.
When in use, at first press and wipe the runin pass, by the energising pool device, motor control assembly control motor is started working, and the driven by motor belt drives rotating shaft 5 rotations, and rotating shaft drives the circular cylinder axle and passs on moving, the circular cylinder axle drives tubular and wipes the work of examination cloth, at this moment just can allow the letter written with chalk on the blackboard carry out wiping automatically, the chalk dust after the wiping is owing to be subjected to stopping of dust excluding plate, and can not float everywhere.Thereby reach the good effect of wiping, also improved teacher's efficient on class and student's the efficient of listening to the teacher.
