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, by a lot of occasion of chalk writing, belong to culture and education fixture fields.
Background technology
Chalk dust problem has had a strong impact on the healthy of people, also causes certain pollution to environment.Electric dustless blackboard eraser mainly contains two types in the market: one is electronic dust suction blackboard and supporting blackboard eraser.It is the derivatives exchanging miniature electronic dust catcher, high pressure dust-absorbing plate is placed in after Glass blackboard or wooden blackboard, with the ordinary blackboard eraser blackboard wiping made with hairbrush or porous material, play the effect of adsorption of dust equally, dust is adsorbed in blackboard eraser.Principle is that dust is attached on plate face in the high-voltage electrostatic field that plate face is formed, and its charge polarity is in neutral.When the blackboard eraser that dust is moved has been wiped, its charge polarity is identical with hardboard polarity and be ostracised, because blackboard eraser polarity under the effect of highfield corona of movement is contrary with hardboard polarity, so the dust wiped by the polarity repulsion of high-pressure polar plate in blackboard eraser hairbrush or porous material, blackboard eraser plays the effect of dust suction; Two is ash-collecting blackboard erasers.Principle utilizes the rotating vane bottom blackboard eraser to rotate to produce air suction, and be drawn into by the dust produced in wiping process in blackboard eraser chamber, dust is sent in dust bag by the relative low pressure produced due to blade, reaches the effect of dust suction.
Although the said goods has been tending towards ripe and technically 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 first should be made to depart from from the appearance dirt face of blackboard eraser; Secondly the chalk dust that reply departs from carries out effective collection and catches.For above problem, on the basis that existing blackboard eraser product is investigated, in conjunction with the knowledge of learned machinery and dust removal by ventilation related fields, invent the electric dustless blackboard eraser that a kind of structure is simple, pick-up performance is good.
Summary of the invention
Proposition of the present invention, is intended to solve the use problem that existing blackboard eraser wiping labour intensity is large, chalk dust is large.
