Abstract
The utility model relates to an automatic dust removal blackboard eraser without dynamic, and the wipe roll which is made into a ring-shaped with a special roller structure which is capable of being turned from outer side into the inner side by rolling side wheel on the blackboard through the roller structure after being adhered with chalk dust which will be cleaned by the hair brush inside the blackboard and fall into a dust-storing box automatically, and then the cleaned wipe roll will be turned to outer side to be used again. The utility model has compact structure, convenient usage, low costs, and fits for all schools.
Description
Technical field the utility model is a kind of blackboard eraser that does not need power to realize dedusting.
The blackboard eraser that background technology is traditional is to do shell by an iron sheet or plastics, and waste and old cotton making herbs into wool hair dress is made within it.Chalk dust flies upward everywhere when erasing the board, and its main cause chalk dust amasss on the blackboard eraser surface and is difficult to remove, and in order to wipe clean blackboard, the user has to beat repeatedly blackboard eraser comes off dust, and this has a strong impact on health and environmental sanitation.The electric dust absorption blackboard eraser that has come into the market is the energy with the dry cell, with hairbrush make dust floating by battery-driven motor with the dust sucking-off, facts have proved that the too big cost of poor effect and battery consumption is too high, be difficult to popularize; Therefore electrostatic precipitation blackboard eraser effect is poorer, and most schools still use traditional blackboard eraser, still the experience evil of chalk dust of Faculty and Students.
The summary of the invention the purpose of this utility model be to provide a kind of fully without power, can realize easily that automatic dedusting and cost are low, be convenient to promote unpowered from dust-removing blackboard eraser.
The purpose of this utility model is achieved in that to be done wiper circlewise, by special roller structure, can move to inside easily after making the wiper Outboard Sections be stained with chalk dust, by placing inner hairbrush dust out to fall in the stored ash box, clean wiper inside part of while forwards the outside to and re-uses.
Description of drawings concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a schematic appearance of the present utility model, and Fig. 2 is a section of structure.
Describe the thin of the concrete device that the utility model proposes in detail below in conjunction with Fig. 1 and Fig. 2 Joint and working condition.
This device comprises panel (1), base (2), side wheel (3), wiper (4), storage Ash box (5), pinion (7), master gear (8), master rotor (9), middle gear (10), Intermediate roll (11) and hairbrush (12). Master rotor (9) is cylinder with intermediate roll (11) Shape hard plastic tube or metal tube, its two ends closely insert respectively moulding with cylindrical socket and axle Expect gear master gear (8) and middle gear (10), be installed in parallel in the inside of panel (1), Middle gear is coupled with two master gears simultaneously, can in the same way synchronized rotation to guarantee two master rotors.
Wiper (4) is done circlewise by the cloth of rub resistance, and------intermediate roll top---master rotor bottom, right side---panel becomes two S shapes to master rotor bottom, left side, and folded by master rotor and intermediate roll in turn around panel.Be installed in concentric pinion (7) and master gear (8) coupling are arranged on the side wheel (3) of the left and right sides of blackboard eraser, strip hairbrush (12) and the parallel contact of wiper (4) are arranged on the base (2), the flat transparent plastic stored ash box (5) of recording quantity is equipped with in the bottom of panel (1) and base (2), directly be enclosed within on the projection (6) of panel and base, when filling chalk dust, can extract and remove chalk dust easily.
4 side wheels (3) are made by rubber or flexible plastic, are installed in the edge, the left and right sides in blackboard eraser front, and each side wheel is all by pinion on it (7) and master gear (8) coupling.Plane, side wheel place is a little less than panel (1), a little more than base both sides of the edge plate washers (13), make that side wheel does not contact with blackboard when erasing the board, raise one side of blackboard eraser, the another side side wheel can roll along the blackboard surface, by pinion (7), master gear (8) and middle gear (10), make master rotor (9) and intermediate roll (11) make backward rotation, cause wiper (4) to move, the chalk dust that glue its outside forwards to and is fallen into stored ash box (5) after inside is removed by hairbrush.
The employing of specific embodiment the utility model is rolled on blackboard by side wheel and is driven the structure that wiper moves, dust on the wiper is removed in blackboard eraser inside, can stop dust floating in air effectively, and does not use the energy fully, with low cost, be easy to penetration and promotion.
Claims (2)
1, a kind of unpowered be by panel from dust-removing blackboard eraser, base, side wheel, wiper, master rotor, intermediate roll, hairbrush, compositions such as stored ash box, it is characterized in that: there are two equal cylindrical master rotors (9) and an intermediate roll (11) in the inside of panel, master rotor is positioned at the both sides of intermediate roll, master rotor, the port of intermediate roll has master gear (8), middle gear (10), middle gear is coupled with two master gears simultaneously, concentric pinion (7) and master gear (8) coupling are arranged on the side wheel (3) of the left and right sides of blackboard eraser, the ring-type wiper of being made by wear-resisting cloth (4) passes through panel front and folded by master rotor and intermediate roll, become two S shapes, strip hairbrush (12) and the parallel contact of wiper (4) are arranged on the base (2), and stored ash box (5) is equipped with in the bottom of panel and base.
2, according to claim 1 unpowered from dust-removing blackboard eraser, it is characterized in that side wheel is that rubber or flexible plastic are made, the end, omited in panel plane, a little more than the base both sides of the edge in its plane, place.
