Description

A kind of novel dust-sucking eraser

The utility model relates to a kind of novel dust-sucking eraser.(IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), and printing branch is write or drawing appliance, the big class of office appliance, write or drawing article, the assistant product group of writing or draw has the blackboard of sucking chalk powder device or the cleaning device technical group field of slabstone.Be numbered B43L21/02.

At present, the technology about the cleaning device of blackboard that the sucking chalk powder device is arranged or slabstone existing and that once had was all done very fruitful effort to the demand of dust-sucking eraser, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Gu Zhengwu, Granted publication number is CN2243398Y, China Patent No. (ZL) is: No. 95221145.9 utility model title is the utility model patent of " drum-type dust-absorbing blackboard brush ", the technical scheme that is adopted.Cleaning device technical elements at blackboard that the sucking chalk powder device is arranged or slabstone is a routine of great value invention, and it has solved the problem that advantage how to utilize cylinder solves blackboard brush effectively.But still have some deficits, it also is difficult to solution and how utilizes frictional electricity, utilizes the problem of the new blackboard wiping of electrostatic precipitation.

The purpose of this utility model is to provide a kind of novel dust-sucking eraser.To solve how to utilize frictional electricity, utilize the problem of the new blackboard wiping of electrostatic precipitation.

The purpose of this utility model is achieved in that a kind of novel dust-sucking eraser of this utility model.Mainly constitute by handle, blackboard eraser housing, fur, copper rod, stored ash box, pour spout.Its major part copper rod is by selecting for use on the market.Handle, blackboard eraser housing are made with molded of plastic material.Fur is made with silk.The utility model is made up of the blackboard eraser housing, and inlay blackboard eraser housing above and below the fur that easily electrifies; Is equipped with copper rod in the middle of the blackboard eraser housing, the copper rod end is welded with plastic handle, square stored ash box is arranged below the blackboard eraser housing, and the stored ash box right flank has circular little pour spout.So just realized the purpose of this utility model.

The utility model has been compared two advantages and improvement with the original blackboard that the sucking chalk powder device is arranged or the cleaning device technology of slabstone;

The first, because the utility model has designed the fur that electrifies in technical scheme, solved the problem of triboelectrification;

The second, because the utility model has designed copper rod in technical scheme, solved problem with the fur friction.Thereby just can more effectively solve how to utilize frictional electricity, utilize the problem of the new blackboard wiping of electrostatic precipitation.

Accompanying drawing provides structural representation of the present utility model:

Fig. 1 is the sectional structure schematic diagram of a kind of novel dust-sucking eraser of the utility model;

Fig. 2 is the side-looking structural representation of a kind of novel dust-sucking eraser of the utility model;

The numbering of parts explanation in the schematic diagram: 1 handle, 2 blackboard eraser housings, 3 furs, 4 copper rods, 5 stored ash box, 6 pour spouts

Below in conjunction with accompanying drawing, the utility model is described further:

As shown in the figure, a kind of novel dust-sucking eraser of the utility model. Mainly by handle 1, blackboard eraser Housing 2, fur 3, copper rod 4, stored ash box 5, pour spout 6 consist of. Its main zero Part copper rod 4 is by selecting on the market. Handle 1, blackboard eraser housing 2 usefulness molded of plastic material are made. Fur 3 usefulness silks are made. The utility model is made up of blackboard eraser housing 2, blackboard eraser housing 2 Inlay the above and below the fur 3 that easily electrifies; Be equipped with copper rod 4, copper in the middle of the blackboard eraser housing 2 Rod 4 ends are welded with plastic handle 1, square stored ash box 5 are arranged below the blackboard eraser housing 2, the storage ash Box 5 right side faces have circular little pour spout 6. So just realized the purpose of this utility model. From And just can solve how to utilize frictional electricity, utilize the problem of the new blackboard wiping of static dust suction.

Below by embodiment, the utility model is done more detailed description:

Embodiment 1, and in use, if turning handle 1, copper rod 4 and then rotates, and produces static with fur 3 frictions, just can utilize the reason of electrostatic precipitation to remove the hard nut to crack that chalk dust flies upward from everywhere when erasing the board.The dust that absorbs is stored in to be inhaled in the grey box, when attracting deposit when a certain amount of, pours out from pour spout 6.Thereby just can realize the purpose of this utility model.

Realize that preferred plan of the present utility model is is material with the silk, utilize the basic equipment of cloth processing factory, take assembling to produce by batch, the demand with supply educational circles so just can realize practical value of the present utility model and economic worth better.
