Abstract
The utility model relates to an electric blackboard eraser which comprises a casing, a motor arranged in the casing, an eraser body driven by the motor and a dust collector arranged in the casing, wherein the casing is in a hollow truncated cone shape whose lower end surface is opened, one end of the upper end surface of the casing is upwards projected, and is gradually inclined and contracted towards the horizontal direction to form a handle, and a switch is arranged on the upper end of the handle. A motor is mounted on the middle portion in the casing, and a disc-shaped eraser body is sleeved on the drive shaft of the motor. A rechargeable battery is arranged on the rear inner wall of the casing, namely the projected lateral inner wall of the upper end of the casing. A small-sized dust collector is mounted on the front inner wall of the casing, and a dust-collecting bin is communicated at the dust collector. The electric blackboard eraser has smart volume and light weight, can absorb dust on a blackboard without leakage, and can be cyclically used through the rechargeable battery.
Description
One, technical field:
The utility model relates to a kind of electric blackboard eraser.
Two, background technology:
The dust-free chalk that uses of teaching now still can produce a large amount of dust when writing and wipe, teacher and the student who is sitting in the front row just inevitably can suck a large amount of dust, thereby causes PUD D.
Three, summary of the invention:
The purpose of this utility model is to propose a kind of easy to use, electric blackboard eraser that pick-up performance is good.
The purpose of this utility model is achieved in that electric blackboard eraser comprises housing, is installed in the motor in the housing, by motor-operated rub body, and is installed in the interior dust catcher of housing.Housing is the uncovered cavity truncated cone-shaped in lower surface, projection on its upper surface one side direction, and tilt, shrink to horizontal direction gradually, form handle, at handle upper end installing switch.Middle part installing motor in housing, socket disc rub body on its power transmission shaft.At housing rear side inwall, promptly convex side inwall place in upper end installs rechargeable battery.At inwall place, housing front side installing Small-sized suction cleaner, the other dust compartment that is communicated with of dust catcher.
The utility model volume is small and exquisite, in light weight, can accomplish dead-tight absorption to the dust on the blackboard, by rechargeable battery, capable of circulationly repeatedly uses.
Four, description of drawings:
Concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is an electric blackboard eraser external structure schematic diagram;
Fig. 2 is an electric blackboard eraser internal structure schematic diagram.
Legend: 1, power line, 2, housing, 3, switch, 4, handle, 5, motor, 6, dust compartment, 7, dust catcher, 8, universal wheel, 9, rub body, 10, rechargeable battery.
Five, the specific embodiment:
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, 2, electric blackboard eraser comprises housing 2, is installed in the motor 5 in the housing 2, the rub body 9 that drives by motor 5, and be installed in dust catcher 7 in the housing 2.Housing 2 is the uncovered cavity truncated cone-shaped in lower surface, projection on its upper surface one side direction, and tilt, shrink to horizontal direction gradually, form handle 4, at handle 4 upper ends installing switch 3.Middle part installing motor 5 in housing 2, socket disc rub body 9 on its power transmission shaft.At housing 2 rear side inwalls, promptly convex side inwall place in upper end installs rechargeable battery 10.At inwall place, housing 2 front side installing Small-sized suction cleaner 7, the dust catcher 7 other dust compartments 6 that are communicated with, dust compartment 6 is embedded on the housing 2.Rechargeable battery 10 is equipped with power line 1, and motor 5 and dust catcher 7 are connected with switch 3 respectively, connects with dropping resistor, rechargeable battery 10 in turn again.Outer wall place, toroidal shell body 2 lower end installing universal wheel 8, universal wheel 8 bottom a little more than rub body 9 bottom.
During use, give rechargeable battery 10 chargings by power line 1 earlier, can use behind to be charged the finishing.Hold handle 4, actuating motor 5, dust catcher 7, this moment, rub body 9 rotated with motor 5.Rub body 9 is close to blackboard, and universal wheel 8 bottoms contact simultaneously in the blackboard surface.The electric blackboard eraser that moves around, dust catcher 7 absorbs the chalk dust that drops, and is collected in the dust compartment 6.After treating to have wiped blackboard, dust compartment 6 is emptied so that use next time at every turn.
Above technical characterictic has constituted most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease inessential technical characterictic according to actual needs, satisfies the needs of different situations.
