Description

The blackboard eraser of sucking chalk powder

(1) technical field:

The utility model relates to the blackboard eraser of sucking chalk powder, presses the technical field that International Patent Classification (IPC) (IPC) is divided the cleaning device group that belongs to blackboard or slabstone.

(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 the blackboard eraser of sucking chalk powder, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China on the 23rd October in 2002 by University Of Shanxi, Granted publication is that CN2517592Y China Patent No. (ZL) is: ZL01274676.2 number utility model patent title is the utility model patent of " a kind of dust-collecting type blackboard eraser ", the technical scheme that is adopted, technical elements in the cleaning device group of blackboard or slabstone is a routine of great value invention, it has solved the pollution that dust from flying causes, the technical problem of good dedusting effect effectively.But still have some deficits, it is unclean that it also is difficult to solve wiping, antihygienic technical problem.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of blackboard eraser of sucking chalk powder unclean to solve wiping, antihygienic technical problem.

The technical scheme that above-mentioned technical problem to be solved in the utility model adopted is achieved in that the blackboard eraser of sucking chalk powder of the present utility model, mainly is made of lid, box body, cotton pad, dust catcher, switch, battery cover, battery, lead.

In shape, structure and combination thereof, the total essential features of the blackboard eraser of sucking chalk powder of the present utility model and immediate prior art is: the top of cotton pad is connected to the bottom of box body, the top of box body is connected to the bottom of lid, be combined into the integrative-structure of square shape, function has been the effect that erases the board.In shape, structure and combination thereof, the blackboard eraser of the sucking chalk powder of the present utility model technical characterictic different with immediate prior art is: the inside that is installed in the box body is inserted in the outside of dust catcher, the bottom of switch is installed in the top of lid, the structure that is combined into one, function has been the effect of sucking chalk powder.The inside that is installed in lid is inserted at the two ends of battery, and the external card of battery cover is installed in the middle part of lid, and the structure that is combined into one, function have been the effects of power supply.The wiping of blackboard eraser that has so just reached sucking chalk powder of the present utility model is unclean, antihygienic purpose.

The beneficial effect of the blackboard eraser of the sucking chalk powder of utility model is that the utility model is solve to wipe untotally, and the technical scheme that antihygienic technical problem adopted 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, insert the inside that is installed in the box body owing to designed the outside of dust catcher in the technical scheme of the blackboard eraser of sucking chalk powder of the present utility model, the bottom of switch is installed in the top of lid, and the structure that is combined into one is so the technical problem of easier solution sucking chalk powder.

The second, insert the inside that is installed in lid owing to designed the two ends of battery in the technical scheme of the blackboard eraser of sucking chalk powder of the present utility model, the external card of battery cover is installed in the middle part of lid, and the structure that is combined into one is so the technical problem of easier solution power supply.

(4) description of drawings:

Accompanying drawing provides the structural representation of the blackboard eraser of sucking chalk powder of the present utility model:

Fig. 1: the whole sectional structure schematic diagram that is the blackboard eraser of sucking chalk powder of the present utility model;

The label declaration at each position in the schematic diagram:

1 lid, 2 box bodies, 3 cotton pad 4 dust catchers

5 switches, 6 battery covers, 7 batteries, 8 leads

(5) specific embodiment:

Below in conjunction with accompanying drawing, unclean for realizing solving wiping to the blackboard eraser of sucking chalk powder of the present utility model, the optimal way of the technical scheme that antihygienic technical problem is taked is described further:

Its static structure: see also accompanying drawing: as shown in the figure, the blackboard eraser of sucking chalk powder of the present utility model mainly is made of lid 1, box body 2, cotton pad 3, dust catcher 4, switch 5, battery cover 6, battery 7, lead 8.The cotton pad 3 of its major part, dust catcher 4, switch 5, battery cover 6, battery 7, lead 8 are selected for use by market.Its lid 1 is a square shape, is material with plastics, through the thermoforming processing and manufacturing.Its box body 2 is square shapes, is material with plastics, through the thermoforming processing and manufacturing.

In shape, structure and combination thereof, the total essential features of the blackboard eraser of sucking chalk powder of the present utility model and immediate prior art is: the top of cotton pad 3 is connected to the bottom of box body 2, the top of box body 2 is connected to the bottom of lid 1, be combined into the integrative-structure of square shape, function has been the effect that erases the board.In shape, structure and combination thereof, the blackboard eraser of the sucking chalk powder of the present utility model technical characterictic different with immediate prior art is: the inside that is installed in box body 2 is inserted in the outside of dust catcher 4, the bottom of switch 5 is installed in the top of lid 1, the structure that is combined into one, function has been the effect of sucking chalk powder.The inside that is installed in lid 1 is inserted at the two ends of battery 7, and the external card of battery cover 6 is installed in the middle part of lid 1, and the structure that is combined into one, function have been the effects of power supply.

Below by using method, further set forth the dynamic structure relation of the blackboard eraser of this practical sucking chalk powder: in use, when needs erase the board, according to theory of mechanics, at first put battery 7, open switch 5 then, erase the board then again, thereby finish erasing the board of task.The wiping of blackboard eraser that has so just realized sucking chalk powder of the present utility model is unclean, the technical scheme of antihygienic technical problem.

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