Description
Technical field
The utility model relates to a kind of blackboard eraser, particularly a kind of automatic blackboard eraser being provided with position sensor.
Background technology
In our daily life at ordinary times and study, especially when school sessions, erasing the board is the indispensability work of every class substantially.When we help teacher to erase the board at every turn, usually can make oneself health to adhere to a large amount of dust and people is felt that arm is ached.But used blackboard eraser often can only realize erasure task, the attachment of dust can not be avoided and alleviate manual labor, harm teacher and classmates healthy.Devise a kind of automatic blackboard eraser being provided with position sensor for above-mentioned present situation, its intelligence is mainly reflected in its automatic blackboard cleaning, automatically turning to close to during blackboard frame.The powder can collecting chalk alleviates pollution to environment, reduces the labour of people, reduces dust when erasing the board to the harm of human body simultaneously.
Summary of the invention
The purpose of this utility model is exactly need manual operation, workload large for existing blackboard eraser, can not realize the problem automatically run, propose a kind ofly can automatically to run, running into blackboard frame can the automatic blackboard eraser of auto-returned.
Its technical scheme is: a kind of automatic blackboard eraser being provided with position sensor, primarily of housing, circular felt, dish type felt box, motor, permanent magnet, knob, position sensor, sensor support base, battery case, battery, bracing frame, bolt, rounded tabs, fixed head, power switch forms, described circular felt is positioned in dish type felt box, described motor is connected with annular felt box, described knob is connected with permanent magnet by the through hole of housing upper end, described battery is positioned in battery case, described sensor is positioned in the groove of sensor support base, described permanent magnet is positioned on bracing frame.
The interior lower end of above-mentioned housing is provided with circular groove, and circular groove is provided with three through holes.
Be provided with a through hole in the middle of above-mentioned circular felt, along the circumferential direction evenly branch 20 long-narrow triangular mesh slotted eyes.
Above-mentioned dish type felt box lower end is cylinder, and offered many along the circumferential direction equally distributed small through hole on the cylinder, dish type felt box upper end is provided with petal gland, and centre is hollow-core construction.
Above-mentioned power switch is positioned at the dead astern of back side of shell battery.
The beneficial effects of the utility model: automatic blackboard eraser employing Double-sucker mechanism utilizes speed discrepancy to realize and moves around.It can be regulated the absorption affinity of blackboard by regulating the angle of permanent magnet N/S pole and blackboard.Be provided with position sensor, can position signalling be detected when blackboard eraser runs into blackboard frame thus avoid bumping against blackboard frame., wiped white powder can also be collected, to prevent it from entering contaminated air in air, harm people's is healthy meanwhile.

Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As shown in figures 1 to 6, a kind of automatic blackboard eraser being provided with position sensor of the utility model, primarily of housing 1, circular felt 2, dish type felt box 3, motor 4, permanent magnet 5, knob 6, position sensor 7, sensor support base 8, battery case 9, battery 10, bracing frame 11, bolt 12, rounded tabs 13, fixed head 14, power switch 15 forms, described circular felt 2 is positioned in dish type felt box 3, described motor 4 is connected with annular felt box 3, described knob 6 is connected with permanent magnet 5 by the through hole of housing upper end, described battery 10 is positioned in battery case 9, described position sensor 7 is positioned in the groove of sensor support base 8, described permanent magnet 5 is positioned on bracing frame 11.
Preferably, described housing 1 interior lower end is provided with circular groove, and circular groove is provided with three through holes.
Preferably, be provided with a through hole in the middle of described circular felt 2, along the circumferential direction evenly branch 20 long-narrow triangular mesh slotted eyes.
Preferably, described dish type felt box 3 lower end is cylinder, and offered many along the circumferential direction equally distributed small through hole on the cylinder, dish type felt box 3 upper end is provided with petal gland, and centre is hollow-core construction.
Preferably, described power switch 15 is positioned at the dead astern of housing 1 back side battery.
Described automatic blackboard eraser will adopt the blackboard containing iron powder materials when using, catch 13 at blackboard on the surface, is positioned in three through holes of housing 1 lower end circular groove by the magnetic absorption utilizing permanent magnet 5.Turn on the power switch 15, motor 4 starts to rotate, and drives the circular felt 2 in dish type felt box 3 to rotate, and adopts Double-sucker mechanism can utilize speed discrepancy to realize and move around by arranging motor 4 rotating speed.By regulating the N/S pole of permanent magnet 5 and the angle of blackboard to regulate it to the absorption affinity of blackboard, and then control the translational speed of automatic blackboard eraser.The position sensor 7 be provided with in the groove of sensor support base 8 can detect when blackboard eraser is about to run into blackboard frame that position signalling changes direction, thus avoids bumping against blackboard frame.The white dust produced when erasing the board, through the long-narrow triangular mesh slotted eye of circular felt 2 along the circumferential direction even branch, then enters in housing 1 by the small through hole of dish type felt box 3, finally falls into the circular groove of housing 1 lower end.Turn off power switch 15 after wiping blackboard, after turning knob 6 reduces absorption affinity, take off blackboard eraser, finally take off the catch 13 of blackboard eraser, clean out white dust in empty capsid 1.Meanwhile, automatic blackboard eraser can also collect wiped white powder, and to prevent it from entering contaminated air in air, harm people's is healthy.
Be illustrated the utility model by way of example above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
