Description

Ash-collecting blackboard eraser

The utility model relates to ash-collecting blackboard 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 ash-collecting blackboard eraser, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Gao Enji, Granted publication number is CN2235906Y, China Patent No. (ZL) is: No. 95230897.5 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 how it solved the electronic problem that erases the board effectively.But still have some deficits, how its also very difficult solution reduces chalk dust when erasing the board flies upward, and the chalk dust that flies upward is collected in the unified together problem of handling.

The purpose of this utility model is to provide a kind of ash-collecting blackboard eraser.How when erasing the board, to reduce chalk dust with solution and fly upward, the chalk dust that flies upward is collected in the unified together problem of handling.

The purpose of this utility model is achieved in that this utility model ash-collecting blackboard eraser.Mainly constitute by dust suction sieve, fan blade, storage flour bag, motor, press button, battery case, battery, iron block, wedge shape lid, lead, motor binding post, blackboard eraser box, column, spring.Its major part motor, battery, spring lead, iron block are by selecting for use on the market.The dust suction sieve is made with the die casting of foam type Sha material.Blackboard eraser box, fan blade are made with plastics.New blackboard is wiped main body and is made of square hollow blackboard eraser box, blackboard eraser box Far Left is equipped with the dust suction sieve, the blackboard eraser box is inserted with the wedge shape lid backmost, blackboard eraser box lower left is stained with square hollow storage flour bag, blackboard eraser box lower right is equipped with battery case, battery is equipped with in the battery case the inside, the battery case outside is connected with draws lead, one of lead end is connected with press button, and press button is inserted in the column, is with spring above the column, two ends of lead are connected on the iron block, be equipped with motor in the middle of the blackboard eraser box, be equipped with two binding posts on the motor, motor is connected with fan blade by motor shaft.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 dust suction sieve in technical scheme, solved and adsorbed the problem of flying upward chalk dust;

The second, because the utility model has designed the storage flour bag in technical scheme, solved the problem of collecting chalk dust.How when erasing the board, to reduce chalk dust and fly upward thereby just can more effectively solve, the chalk dust that flies upward is collected in the unified together problem of handling.

Accompanying drawing provides structural representation of the present utility model:

Fig. 1 is the sectional structure schematic diagram of the utility model ash-collecting blackboard eraser;

Fig. 2 is the on-off circuit sectional structure schematic diagram of the utility model ash-collecting blackboard eraser;

The numbering of parts explanation in the schematic diagram: 1 dust suction is sieved 2 fan blade, 3 storage flour bags, 4 motors, 5 press buttones, 6 battery cases, 7 batteries, 8 iron blocks, 9 wedge shapes and is covered 10 leads, 11 motor binding posts, 12 blackboard eraser boxes, 13 columns, 14 springs

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

As shown in the figure, the utility model ash-collecting blackboard eraser.Mainly constitute by dust suction sieve (1), fan blade (2), storage flour bag (3), motor (4), press button (5), battery case (6), battery (7), iron block (8), wedge shape lid (9), lead (10), motor binding post (11), blackboard eraser box (12), column (13), spring (14).Its major part motor (4), battery (7), spring (14) lead (10), iron block (8) are by selecting for use on the market.Dust suction sieve (1) is made with the die casting of foam type Sha material.Blackboard eraser box (12), fan blade (2) are made with plastics.New blackboard is wiped main body and is made of square hollow blackboard eraser box (12), blackboard eraser box (12) Far Left is equipped with dust suction sieve (1), blackboard eraser box (12) is inserted with wedge shape lid (9) backmost, blackboard eraser box (12) lower left is stained with square hollow storage flour bag (3), blackboard eraser box lower right is equipped with battery case (6), battery (7) is equipped with in battery case (6) the inside, battery case (6) outside is connected with draws lead (10), one of lead (10) end is connected with press button (5), press button (5) is inserted in column (13) lining, be with spring (14) above the column (13), two ends of lead (10) are connected on the iron block (8), be equipped with motor (4) in the middle of the blackboard eraser box (12), be equipped with two binding posts (11) on the motor (4), motor (4) is connected with fan blade (2) by motor shaft.So just realized the purpose of this utility model.How when erasing the board, to reduce chalk dust and fly upward thereby just can solve, the chalk dust that flies upward is collected in the unified together problem of handling.
