Abstract
The utility model relates to an erasing device driven by a motor (1). The eraser fixes a cylindrical hair brush (3) on the shaft of the motor (2), and the outer side of the hair brush (3) is covered with a cylinder casing (6). The periphery of the casing (6) of the hair brush is provided with an erasing opening (5) and a dust discharging opening. The dust discharging opening is communicated with a dust collecting chamber (7). In use, the erasing opening (5) is contacted with the surface of the erased thing, and the motor (1) drives the hair brush (3) rotate. The hair of the hair brush (4) erases the dust, and because of the centrifugal action, the dust erased is threw out the dust discharging opening and enters the dust collecting chamber. The eraser collects the dust at the same time of erasing the objects.
Description
The utility model is with the blackboard wiping of small size motor drive and the apparatus of other objects.
Present blackboard eraser be fixed on the plank with felt rug or the iron sheet box in constitute.Driving it with manpower rubs off chalk marks.Its major defect is chalk powder can not be collected, and chalk powder flies upward everywhere, makes air pollution in the classroom, influences SH.
Remove the dust catcher that has of other body surface dust now.Dust catcher utilizes draught head to come work.Inhale not sticking in the relatively more firm dust of body surface like this, need manpower to move cleaner head dust is wiped, again it is sopped up, this dust suction mode is not case type, but opening, the dust of having wiped with cleaner head, some is leaked away inevitably, flies in the air.For example erase the board with dust catcher, always some will waft to indoor the chalk powder of having wiped.Structure of dust collector complexity in addition, the cost height, volume is big, and it is convenient inadequately to use.
The purpose of this utility model is that a kind of motor-operated wiper will be provided, rub off chalk marks or other body surface dust in, dust collection is got up, prevented the pollution of dust effectively to indoor environment.
The utility model is to realize like this, fix a cylindrical brush on a small size motor axle, with a circular housing hairbrush is covered, the periphery of hairbrush shell is opened a wiping mouth and a dust-exhausting port, the wiping mouth has just had bristle to expose, and dust-exhausting port directly communicates with dust storage chamber.During use, the wiping mouth is fully contacted with wiping the thing surface, the motor drives hairbrush rotates, and bristle is wiped chalk writing or dust at the wiping mouth, and the powder of having wiped, dust enter dust storage chamber because centrifugal action is thrown out of dust-exhausting port, are collected.Hairbrush is fixed on dual mode on the motor reel: the first is installed in motor one side with hairbrush, and motor and hairbrush link together side by side; It two is that hairbrush is enclosed within outside the motor, and motor is in the inside of brush tube.
The utility model is simple in structure, and volume is little; Can neatly things such as blackboard be wiped clean rapidly; The powder of having wiped, dust are firmly being covered by the hairbrush shell, and this dust suction mode is case type, and powder, dust all are collected, and can prevent the pollution to indoor environment of powder, dust effectively.
Concrete structure of the present utility model is provided by following drawings and Examples.
Fig. 1, Fig. 2 all are profiles of the present utility model.Fig. 1 is the profile that cylindrical brush is installed in motor one side.Fig. 2 is after the cylindrical shape hairbrush is fixed on the motor reel, with the profile of engine casing (Eng Cas) in hairbrush.
Describe the utility model concrete structure and working condition in detail below in conjunction with Fig. 1, Fig. 2.
This wiper comprises a motor (1); fix a cylindrical brush (3) on the motor reel (2); hairbrush (3) is to be inserted on the side of cylinder bracket by bristle to constitute; on motor (1), fix the hairbrush shell (6) of a circle again; hairbrush (3) is covered; the place, neighboring of hairbrush shell (6) opens a wiping mouth (5); wiping mouth (5) locates just to have bristle (4) to expose; a dust-exhausting port is opened in another place in the neighboring of hairbrush shell (6); directly communicate with dust storage chamber (7); leave the perhaps many apertures in slit (9) on the control of dust locular wall (8); be lined with filter course (10) in the control of dust locular wall (8); when blackboard wiping or other body surface; wiping mouth (5) and quilt are wiped the thing surface fully to be contacted; closed telegraph key; motor (1) drives hairbrush (3) and rotates; bristle (4) is wiped chalk writing or dust at wiping mouth (5); the powder of having wiped; dust is along with hairbrush (3) rotates in hairbrush shell (6); because centrifugal action; powder; dust is thrown out of dust-exhausting port, enters dust storage chamber (7).Enter the air in the dust storage chamber (7), see through the slit or the aperture (9) of filter course (10) and control of dust locular wall (8), discharge the external world, and powder, dust are stayed in the dust storage chamber (7), are collected.
Hairbrush (3) is fixed on dual mode on the motor reel (2): the first is installed in motor (1) one side with hairbrush (3), and motor (1) and hairbrush (3) link together side by side, as shown in Figure 1; It two is that hairbrush (3) is enclosed within outside the motor (1), and motor (1) is in the inside of brush tube, as shown in Figure 2.
Motor (1) all can with direct current generator and alternating current generator.When using direct current generator, need self-contained battery folder on this wiper; When using alternating current generator, this wiper need have long power line (11) to link to each other with the indoor power supply socket.
Claims (5)
1, a kind of electric dust absorption wiper, of the present utility model being characterised in that fixed a cylinder (or cylinder) shape hairbrush (3) on the motor reel (2), fix the hairbrush shell (6) of a circle on motor (1), hairbrush (3) is covered, there is a dust storage chamber (7) in the edge of hairbrush shell (6).
2, wiper according to claim 1 is characterized in that the place, neighboring of hairbrush shell (6) opens a wiping mouth (5) and a dust-exhausting port, and wiping mouth (5) locates just to have bristle (4) to expose, and dust-exhausting port directly communicates with dust storage chamber (7).
