Description

The dust suction chalkboard eraser

(1) technical field:

The utility model relates to the dust suction chalkboard eraser, divides by International Patent Classification (IPC) (IPC) to belong to operation; Department of Transportation, printing branch is write or drawing appliance; The big class of office appliance is write or drawing article; The assistant product group of writing or draw, the cleaning device technical group field of 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 demand of dust suction chalkboard eraser, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Wang Weidong, Granted publication is CN2229359Y, China Patent No. (ZL) is: No. 95239745.5 utility model patent title is the utility model patent of " omnipotent erasing rubber ", 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 omnipotent technical problem of erasing rubber effectively.But still have some deficits, it also is difficult to solve the technical problem that absorbs chalk dust.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of dust suction chalkboard eraser.To solve the technical problem that absorbs chalk dust.

The dust suction chalkboard eraser that the new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is achieved in that this utility model mainly by: hairbrush, switch, chalkboard eraser box, brush plate, battery, aperture, mini-fan, lead, hinge constitute.Its major part switch, battery, lead, hinge, mini-fan are selected for use by market.Its hairbrush is the slice shape, is material with the fiber, through the pull processing and manufacturing.Its chalkboard eraser box is a rectangular shape, is material with timber, through the turner processing and manufacturing.Its brush plate is that cuboid contains hole shape, is material with timber, through the turner processing and manufacturing.

In shape, structure and combination thereof, the total essential features of dust suction chalkboard eraser of the present utility model and immediate prior art is: the long end position outpost of the tax office, the left side of brush plate is installed in the position of the long end in the right side of chalkboard eraser box, two fan position screws of hinge are installed in the long end in the right side of brush plate, chalkboard eraser box, the position of Zuo Changduan, be combined into the fixed structure of box-like shape, function has been the effect that does not make brush plate movable arbitrarily.The integral position screw of switch is installed in the position of the long end bottom, the right side of chalkboard eraser box, is combined into the fixed structure of switch shape, and function has been the effect of control power supply.In shape, structure and combination thereof, the dust suction chalkboard eraser of the present utility model technical characterictic different with immediate prior art is: the both positive and negative polarity position of battery is connected electrically in the position of depositing the battery place of chalkboard eraser box, the end positions of switch is connected electrically in the position at the two ends of lead, be combined into the line construction of closed circuit shape, function has been the effect of energising.The integral position screw of mini-fan is installed in the position of the inside of chalkboard eraser box, and the end positions of lead is connected electrically in the position of the binding post of mini-fan, is combined into the line construction of closed circuit shape, and function has been the effect to the mini-fan energising.So just realized that dust suction chalkboard eraser of the present utility model solves the purpose of the technical problem that absorbs chalk dust.

The beneficial effect of the dust suction chalkboard eraser of utility model is that to be the solution technical scheme that technical problem adopted that absorbs chalk dust compared two place's advantage and improvement with existing with the technology about the cleaning device group of blackboard or slabstone that once had to the utility model:

First, because the both positive and negative polarity position of having designed battery in the technical scheme of dust suction chalkboard eraser of the present utility model is connected electrically in the position of depositing the battery place of chalkboard eraser box, the end positions of switch is connected electrically in the position at the two ends of lead, be combined into the line construction of closed circuit shape, so the technical problem of easier solution energising.

Second, because the integral position screw that has designed mini-fan in the technical scheme of dust suction chalkboard eraser of the present utility model is installed in the position of the inside of chalkboard eraser box, the end positions of lead is connected electrically in the position of the binding post of mini-fan, be combined into the line construction of closed circuit shape, so easier solution is to the technical problem of mini-fan energising.
