Abstract

The utility model relates to a dust-absorbing blackboard eraser. The purpose is to solve the problems of large dust at blackboard wiping time and resource saving. The utility model is composed of an eraser board, a trademark, a handle, a chalk dust groove, a chalk dust casing, a magnetic layer, a chalk cover and a chalk. The utility model is characterized in that the lower end of the chalk dust casing is stuck and arranged on the upper end of the magnetic layer, the lower end of the magnetic layer is stuck and arranged on the back side of the eraser board, the bottom side of the chalk dust groove is stuck and arranged in the chalk dust casing, and the upper part of the chalk dust casing is directly arranged below the chalk cover. The utility model uses equipment of the daily service processing factory to produce in bulk so as to satisfy the requirement of the educational circles.

Description

Dust-sucking eraser

(1) technical field:

The utility model relates to dust-sucking eraser, divides the technical field of the cleaning device group that belongs to blackboard or slabstone by International Patent Classification (IPC) (IPC).

(2) background technology:

At present, the technology about the cleaning device group of blackboard or slabstone existing and that once had was all done very fruitful effort to the needs of dust-sucking eraser, also once designed many outstanding technical schemes.As on September 15th, 2004 Decree of Patent Office of China by the side according to declaring, Granted publication is that CN2640768Y China Patent No. (ZL) is: ZL02227314.X number utility model patent title is the utility model patent of " blackboard erasing machine ", the technical scheme that is adopted, technical elements in the cleaning device group of blackboard or slabstone is a routine of great value invention, and it has solved the technical problem of clean cleaning blackboard effectively.But still have some deficits, dust was big when its also very difficult solution erased the board, and saved the technical problem of resource.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of dust-sucking eraser.Dust is big when erasing the board with solution, saves the technical problem of resource.

The new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is: dust-sucking eraser of the present utility model mainly is made of wiping board, trade mark, handle, an ash-pit, the grey shell of pen, magnetosphere, cap, chalk.

In shape, structure and combination thereof, the total essential features of dust-sucking eraser of the present utility model and immediate prior art is: the bottom of handle paste be installed in trade mark above, the following stickup of trade mark is installed in the back side of wiping board, be combined into the integrative-structure of blackboard eraser shape, function has been the effect that erases the board.In shape, structure and combination thereof, the dust-sucking eraser of the present utility model technical characterictic different with immediate prior art is: the upper end that is installed in magnetosphere is pasted in the lower end of the grey shell of pen, the back side that is installed in wiping board is pasted in the lower end of magnetosphere, be combined into the fixed structure of rectangular shape, function has been that an ash that will have magnetic drinks up, and prevents the effect of dust.The inside that is installed in the grey shell of pen is pasted in the bottom surface of ash-pit, be directly installed on above the grey shell of pen cap below, be combined into the bascule of rectangular shape, function has been to utilize chalk dust to reproduce into the effect of chalk use.Dust is big when so just having reached the erasing the board of dust-sucking eraser of the present utility model, and saves the purpose of resource.

The beneficial effect of the dust-sucking eraser of utility model is that the utility model is that to solve when erasing the board dust big, and the technical scheme that technical problem adopted of saving resource has been compared two place's advantage and improvement with existing with the technology about the cleaning device group of blackboard or slabstone that once had:

First, paste the upper end that is installed in magnetosphere owing to designed the lower end of the grey shell of pen in the technical scheme of dust-sucking eraser of the present utility model, the back side that is installed in wiping board is pasted in the lower end of magnetosphere, be combined into the fixed structure of rectangular shape, drink up so easier solution will have an ash of magnetic, prevent the technical problem of dust.

Second, paste the inside that is installed in the grey shell of pen owing to designed the bottom surface of an ash-pit in the technical scheme of dust-sucking eraser of the present utility model, the pen grey shell above be directly installed on cap below, be combined into the bascule of rectangular shape, so easier solution utilizes chalk dust to reproduce into the technical problem that chalk uses.

(5) specific embodiment:

Below in conjunction with accompanying drawing, dust was big when dust-sucking eraser of the present utility model was erased the board for realizing solving, and the optimal way of the technical scheme that the technical problem of saving resource is taked is described further:

Its static structure: see also accompanying drawing: as shown in the figure, dust-sucking eraser of the present utility model mainly is made of wiping board 1, trade mark 2, handle 3, an ash-pit 4, the grey shell 5 of pen, magnetosphere 6, cap 7, chalk 8.Its major part wiping board 1, trade mark 2, handle 3 are selected for use by market.Its ash-pit 4 is semi-cylindrical form, is material with plastics, through the thermoforming processing and manufacturing.Its grey shell 5 of pen is rectangular shapes, is material with plastics, through the thermoforming processing and manufacturing.Its magnetosphere 6 is rectangular shapes, is material with magnet, through the machining manufacturing.Its chalk 8 is cylindrical shapes, is material with an ash of being with magnetic, through the machining manufacturing.

In shape, structure and combination thereof, the total essential features of dust-sucking eraser of the present utility model and immediate prior art is: the bottom of handle 3 paste be installed in trade mark 2 above, the following stickup of trade mark 2 is installed in the back side of wiping board 1, be combined into the integrative-structure of blackboard eraser shape, function has been the effect that erases the board.In shape, structure and combination thereof, the dust-sucking eraser of the present utility model technical characterictic different with immediate prior art is: the upper end that is installed in magnetosphere 6 is pasted in the lower end of the grey shell 5 of pen, the back side that is installed in wiping board 1 is pasted in the lower end of magnetosphere 6, be combined into the fixed structure of rectangular shape, function has been that an ash that will have magnetic drinks up, and prevents the effect of dust.The inside that is installed in the grey shell 5 of pen is pasted in the bottom surface of ash-pit 4, be directly installed on above the grey shell 5 of pen cap 7 below, be combined into the bascule of rectangular shape, function has been to utilize chalk dust to reproduce into the effect of chalk use.

Below by using method, further set forth dust-sucking eraser dynamic structure relation of the present utility model: in use, when needs erase the board, according to physical principle, at first pick up the handle 3 of blackboard eraser, be placed on the blackboard then, erase the board then again, thereby finish erasing the board of task.

In use, when needs reproduce chalk,, at first erase the board, put into the bond pen then, cover cap 7 more then and handle, thereby finish the task of reproducing chalk according to physical principle.Dust is big when so just having realized the erasing the board of dust-sucking eraser of the present utility model, and saves the technical scheme of the technical problem of resource.

Realize that preferred plan of the present utility model is is material with plastics, iron, utilize the basic equipment of daily processing factory, take small serial production,, so just can realize the practical value and the economic worth of dust-sucking eraser of the present utility model better with the demand of supply educational circles.
