Abstract
The utility model relates to a rotating-roller type dust-collection eraser, which comprises an eraser body and a control system. A battery pack supplies power for motors. A driving motor drives roller shafts of a pair of matched roller brushes to rotate through a first-level reducing gear pair and a second-level reducing gear pair, and each roller brush is a tubular erasing roller which is formed by winding a layer of soft wear-resisting fibers outside a sponge body with an adsorption function. A dust collection motor drives a suction fan to rotate to suck chalk dust on the roller brushes through a dust collection port, and the chalk dust enters a dust collecting box through a dust outlet. When the dust collecting box is full of the chalk dust, a position sensor sends a signal for alarming, and the dust collecting box is pulled out to discard the chalk dust. An eraser grasping cover is easy to hold, and patterns for increasing friction are carved on the eraser grasping cover. The eraser grasping cover is connected with the eraser body through screws, and a switch, which is easily pressed by an index finger, is installed on the eraser grasping cover. Magnetic bars are installed around the lower side of the eraser body, and the magnetic force is controlled by a magnetic controller and the switch. The rotating-roller type vacuum eraser has the advantages of compact structure, good motion performance, environmental protection and the like, relieves the labor intensity of a teacher for erasing a blackboard, and reduces flying chalk dust.
Description
Technical field
The utility model technology relates generally to a kind of electric blackboard eraser, is specially adapted to belong to culture and education utensil field with a lot of occasion of chalk writing.
Background technology
The chalk dust problem has had a strong impact on the healthy of people, also environment has been caused certain pollution.Electric dust-less blackboard is wiped and is mainly contained two types in the market: the one, and electronics dust-absorbing blackboard and supporting blackboard eraser.It is the derivatives that exchange the miniature electronic dust catcher, the high pressure dust-absorbing plate is placed Glass blackboard or wooden blackboard back, with having the ordinary blackboard eraser blackboard wiping that hairbrush or porous material are made, play the effect of absorption dust equally, dust is adsorbed in the blackboard eraser.Principle is that dust is attached on the plate face in the high-voltage electrostatic field that the plate face forms, and it is neutral that its charge polarity is.When the blackboard eraser that dust is moved is wiped time-out, its charge polarity is identical with hardboard polarity and be ostracised, because mobile blackboard eraser polarity under the effect of highfield corona is opposite with hardboard polarity, so in blackboard eraser hairbrush or porous material, blackboard eraser plays the effect of dust suction to the dust of having wiped by the polarity repulsion of high-pressure polar plate; The 2nd, ash-collecting blackboard eraser.Principle is to utilize the rotating vane rotation of blackboard eraser bottom to produce air suction, and the dust that produces in the wiping process is drawn in the blackboard eraser chamber, because the relative low pressure that blade produces is sent into dust in the dust bag, reaches the effect of dust suction.
Though the said goods has been tending towards ripe technically and in the educational system extensive use of developed country such as American-European-Japanese, the structure of dust collector more complicated of above-mentioned electric blackboard eraser, expensive, be difficult to apply in China.
Solve the environmental pollution problems of removing chalk dust, dust is broken away from from the appearance dirt face of blackboard eraser; Secondly the chalk dust of reply disengaging carries out effective collection and catches.At above problem, on the basis that existing blackboard eraser product is investigated, in conjunction with the knowledge of the machinery of learning and dust removal by ventilation related fields, invented a kind of electric dust-less blackboard simple in structure, that pick-up performance is good and wiped.
