Abstract
The utility model relates to the field of teaching tools, specifically to a dust-free motor-driven eraser, which is capable of preventing pollution of air by dust. The dust-free motor-driven eraser comprises a housing and dust erasing heads disposed on the housing; the lower surface of the housing is provided with a plurality of dust collection holes; the inward side of the dust collection holes is provided with a dust collection device and the outward side of the dust collection holes is provided with the dust erasing heads; rotating shafts of the dust erasing heads are connected with an output shaft of a motor; the dust collection device and the motor are disposed in an installation box on one end of the housing; the other end of the housing is provided with a battery box; and a switch is disposed between the installation box and the battery box. The motor drives the dust erasing heads to rotate and clean a black board and dust falling during erasing is collected by the dust collection device in the installation box, so the dust is prevented from scattering in air and environment for teaching and student learning is improved.
Description
Technical field
The utility model relates to the teaching aid field, is specifically related to a kind of dustless electric eraser.
Background technology
At present, the most of schools of China also do not have the penetration of electron projecting apparatus, the chalk blackboard instrument of giving lessons that still is absolutely necessary, and during the teaching, total bound blackboard several times of wiping.But common blackboard eraser is difficult to blackboard eraser clean, and the time spent relatively requires great effort, and dust flies upward in air everywhere, teacher and classmate's health is brought injury, very not environmental protection.
The utility model content
The purpose of the utility model provides a kind of dustless electric eraser, avoids the pollution of dust to air.
For realizing above-mentioned purpose, the utility model adopts following technical scheme, a kind of dustless electric eraser; Comprise the brush head on housing and setting and the housing, the lower surface of described housing is provided with several air suction openings, and the inboard of air suction opening is provided with dust collect plant; The arranged outside brush head of air suction opening, the rotating shaft of brush head connects the output shaft of motor, and dust collect plant and motor are located in the mounting box of housing one end; The housing other end is provided with battery case, is provided with switch between mounting box and the battery case.
Through above technical scheme; Thereby driven by motor brush head rotates blackboard is carried out wiping; The dust that drops in the wiping process is collected by the dust collect plant in the blackboard eraser mounting box, has prevented that effectively dust from flying upward in air everywhere, has improved teaching and Students'learning environment.

The specific embodiment
Further describe the utility model below in conjunction with accompanying drawing
A kind of dustless electric eraser; Comprise the brush head 20 on housing 10 and setting and the housing 10, the lower surface of housing 10 is provided with several air suction openings 11, and air suction opening 11 communicates with the inner chamber of housing 10; The inboard of air suction opening 11 is provided with dust collect plant 30; The arranged outside brush head 20 of air suction opening 11, the rotating shaft of brush head 20 connects the output shaft of motor 40, and dust collect plant 30 is located in the mounting box 12 of housing 10 1 ends with motor 40; Housing 10 other ends are provided with battery case 13, are provided with switch 14 between mounting box 12 and the battery case 13.When touch switch 14, motor will drive brush head 20 and rotate, and brush head 20 just can carry out wiping to blackboard like this, and in wiping process, the aerial diffusion of dust has been avoided in the inside that the dust that drops is collected housing 10 by dust collect plant 30.Dust collect plant 30 is installed in the mounting box in the housing 10 with motor 40, has reduced dustless electric eraser volume, has made things convenient for teacher or student's use.Thereby being used to install battery, battery case 13 electric energy is provided for motor.
In order to strengthen the wiping effect of brush head 20, brush head 20 is two, and the turning cylinder of the turning cylinder of two brush heads 20 and motor 40 all is connected with travelling gear 50, and each travelling gear 50 is meshing with each other.So just can the electric energy of motor 40 be converted into the mechanical energy of brush head 20 motions, motor effectively has been delivered to power on each brush head 20, guarantee the completion of wiping action.
Described dust collect plant 30 comprises dust catcher 31; The air entry of dust catcher 31 is provided with the inside upper part of air suction opening 11; The exhaust outlet of dust catcher 31 is communicated with the inside box mouth of dust Storage Box 32, and downside and its outer box mouth that dust storage box 32 is located at motor 13 are positioned on the housing 10.Dust catcher 31 starts with motor 40 synchronously; As long as motor 40 drives 20 work of brush head, dust catcher 31 will suck the dust that drops in the dust Storage Box 32, when filling dust in the dust Storage Box 32; Can its taking-up be cleared up it, and then put back to and continue in the housing 10 to use.
Further, in order to prevent that in wiping process the dust that is scattered is diffused in the air, the outer peripheral of described brush head 20 is provided with dust shield case 60, and the wiping portion of brush head 20 is revealed in the box mouth place of dust shield case 60.So just can more effectively prevent being scattered of dust.
Teacher or the dustless electric eraser of student's grasping for ease, described switch 14 push switch that left and right sides shell fragment constitutes of serving as reasons.In to the blackboard eraser grasping, as long as a little firmly clamping switch 14 just can make motor 40 dust catcher 31 work.
The foregoing description, just the preferred embodiment of the utility model is not to be used for limiting the utility model practical range, so all equivalences of being done with the said content of the utility model claim change, all should be included within the utility model claim scope.
