Abstract
An autorotation roller type dust absorption blackboard eraser comprises a blackboard eraser body and a control system. Electricity is supplied to a motor through a battery pack. A drive motor drives a pair of roller shafts to rotate through the fact that a primary reduction gear pair and a secondary reduction gear pair, wherein the pair of roller shafts are provided with roller erasers installed in a sleeved mode. Each roller eraser is a cylindrical wiping roller composed of a spongy body and a layer of soft abrasion resistant fibers, wherein the spongy body has an absorption function, and the layer of soft abrasion resistant fibers surrounds the spongy body. A dust absorption motor drives an air suction fan to rotate. Chalk dust stuck to the roller erasers is absorbed through a dust adsorption port and enters a dust accumulation box through a dust outlet. When the dust accumulation box is full of the chalk dust, a position sensor sends out a signal for warning. The dust accumulation box is pulled out and the chalk dust is poured. A blackboard eraser handheld cover is easy to hold in shape. Decorative patterns used for increasing friction are arranged on the blackboard eraser handheld cover in an engraved mode. The blackboard eraser handheld cover is connected with the blackboard eraser body through bolts. A switch capable of being easily pressed by an index finger is installed on the blackboard eraser handheld cover. Magnetic force strips are installed on the periphery of the lower side of the blackboard eraser body. The magnetic force is controlled through a magnetic force controller and the switch. The autorotation roller type dust absorption blackboard eraser has the advantages of being compact in structure and good in motion performance, relieving labor intensity of a teacher for wiping a blackboard, reducing the amount of spreading chalk dust, and being environment-friendly, healthy and the like.
Description
Technical field
The technology of the present invention relates generally to a kind of electric blackboard eraser, is specially adapted to a lot of occasion of chalk writing, belongs to culture and education utensil field.
Background technology
The chalk dust problem has had a strong impact on the healthy of people, also environment has been caused certain pollution.Electric dustless blackboard eraser mainly contains two types in the market: the one, and electronic dust suction blackboard and supporting blackboard eraser.It is the derivatives that exchange the miniature electronic dust catcher, the high pressure dust-absorbing plate is placed in Glass blackboard or wooden blackboard back, use the ordinary blackboard eraser blackboard wiping made from hairbrush or porous material, play equally the effect of absorption dust, dust is adsorbed in 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 wiping process is drawn in the blackboard eraser chamber, because the relative low pressure that blade produces is sent into dust in dust bag, reaches the effect of dust suction.
Although the said goods has been tending towards ripe technically and in the educational system extensive use of the 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 problem of the environmental pollution 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 effectively collecting and catching.For 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 simple in structure, electric dustless blackboard eraser that pick-up performance is good.
Summary of the invention
