Description

Dust-free black board eraser

The utility model relates to dust-free black board 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 B43L 21/02.

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-free black board eraser, also once designed many outstanding technical schemes.As being declared by Gao Enji of the Decree of Patent Office of China in 1996, Granted publication number is CN2235906Y, and China Patent No. (ZL) is: 95230897.No. 5 utility model title is the utility model patent of " electric dust absorption blackboard eraser ", 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 of blackboard eraser electric dust absorption effectively.But still have some deficits, the blackboard before it also is difficult to solve has brushed the problem that dust is everywhere.

The purpose of this utility model is to provide a kind of dust-free black board eraser.Brushed the problem that dust is everywhere to solve former blackboard.

The purpose of this utility model is to realize like this; This utility model dust-free black board eraser.Mainly constitute by screw, water inlet, lower box body, burlap, screw, upper cartridge body, cavernous body.Its major part screw, screw, burlap are by selecting for use on the market.Its upper cartridge body, lower box body are square shapes, make material with plastics, through the Plastic Forming processing and manufacturing.Its cavernous body is a square shape, makes material with sponge, through shearing processing and manufacturing.The upper cartridge body of its square shape adopts the screw attachment method to be installed on the lower box body of square shape.Form the draw bail of a square shape.The cavernous body of its square shape adopts embedding grammar to be installed in the upper cartridge body inside of square shape.Form the draw bail of a cubic box-like shape.The burlap of its square shape adopts the outer cover method to be installed on the lower box body of square shape.Form the draw bail of a square shape.The water inlet of its T shape shape adopts adhesive method to be installed on the upper cartridge body of square shape.Form the draw bail of a square shape.Its water inlet acts on cavernous body by upper cartridge body.Thereby make cavernous body satisfy the requirement of suction.Its upper cartridge body acts on lower box body by screw.Thereby make upper cartridge body finish the task of assembling.So just realized the purpose of this utility model.

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

The first, because the utility model has designed burlap in technical scheme, so solved the cleaner problem of wiping;

The second, because the utility model has designed water inlet in technical scheme, so solved the problem that can keep the sponge water-filling;

The 3rd, because the utility model has designed upper cartridge body and lower box body in technical scheme, so solved the problem that structure is tightly played.Thereby the blackboard before just more effectively having solved has brushed the problem that dust is everywhere.

Accompanying drawing provides structural representation of the present utility model:

Fig. 1 is the agent structure schematic diagram of the utility model dust-free black board eraser;

The numbering of parts explanation in the schematic diagram: 1 screw, 2 water inlets, 3 lower box bodies, 4 burlaps, 5 screws, 6 upper cartridge bodies, 7 cavernous bodies

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

As shown in the figure, the utility model dust-free black board eraser.Mainly constitute by screw 1, water inlet 2, lower box body 3, burlap 4, screw 5, upper cartridge body 6, cavernous body 7.Its major part screw 1, screw 5, burlap 4 are by selecting for use on the market.Its upper cartridge body 6, lower box body 3 are square shapes, make material with plastics, through the Plastic Forming processing and manufacturing.Its cavernous body 7 is square shapes, makes material with sponge, through shearing processing and manufacturing.The upper cartridge body 6 of its square shape adopts the screw attachment method to be installed on the lower box body 3 of square shape, forms the draw bail of a square shape.The cavernous body 7 of its square shape adopts embedding grammar to be installed in upper cartridge body 6 inside of square shape.Form the draw bail of a cubic box-like shape.The burlap 4 of its square shape adopts the outer cover method to be installed on the lower box body 3 of square shape.Form the draw bail of a square shape.The water inlet 2 of its T shape shape adopts adhesive method to be installed on the upper cartridge body 6 of square shape.Form the draw bail of a square shape.Its water inlet 2 acts on cavernous body 7 by upper cartridge body 6.Thereby make cavernous body 7 satisfy the requirement of suction.Its upper cartridge body 6 acts on lower box body 3 by screw 5.Thereby make upper cartridge body 6 finish the task of assembling.So just realized the purpose of this utility model.Thereby the blackboard before just having solved has brushed the problem that dust is everywhere.

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

Embodiment 1, in force, if use should be novel the time, opens water inlet 2, and water is poured into upper cartridge body 6, and infiltration cavernous body 7 penetrates on the burlap 4 by the hole under the upper cartridge body 6, thereby makes burlap 4 be in dampness, comes blackboard wiping with it then.

Embodiment 2, in force, if adopt the method blackboard wiping, because burlap 4 is moist, do not play dust when therefore erasing the board, the phenomenon that can not cause chalk dust disorderly to fly, thus help health, and wiping is cleaner.Thereby just can realize the purpose of this utility model.

Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of plastic processing factory, take Plastic Forming to produce by batch, the demand with supply consumption circle so just can realize practical value of the present utility model and economic worth better.
