Description

Dust absorption blackboard eraser

(1) technical field:

The utility model relates to dust absorption blackboard 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 absorption blackboard eraser, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Liu Guojia, Granted publication is that CN2216933Y China Patent No. (ZL) is: ZL94218538.2 number utility model patent title is the utility model patent of " blackboard wiper ", 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 large tracts of land cleaning blackboard effectively.But still have some deficits, it also is difficult to solve chalk dust and wafts in air the technical problem that can not collect.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of dust absorption blackboard eraser.Waft the technical problem that can not collect in air to solve chalk dust.

The new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is: dust absorption blackboard eraser of the present utility model mainly is made of plastic housing, power pack, switch, motor, dust-absorbing fan, shoulder pad net, collection box, hairbrush.

In shape, structure and combination thereof, the total essential features of dust absorption blackboard eraser of the present utility model and immediate prior art is: the root of hairbrush is bonded in the lower surface of blackboard eraser, be combined into the integrative-structure of blackboard eraser shape, function has been the effect that erases the board.In shape, the structure and in conjunction with last, the dust absorption blackboard eraser of the present utility model technical characterictic different with immediate prior art is: the right-hand member lead of power pack is connected the lower end of switch, the lower end lead of switch is connected the left end of motor, the lower end of motor is threaded in the upper end of dust-absorbing fan, the lower end of dust-absorbing fan is threaded in the internal thread place, upper end of shoulder pad net, power pack and switch, motor, dust-absorbing fan links to each other by lead, constitute closed circuit, each component fixedly is nested in the inside of plastic housing, the structure that is combined into one, function is the effect of starting power dust suction.The lower end of plastic housing is embedded in the upper end of collecting box, and the lower end of collecting box is bonded at the upper end of hairbrush, is combined into the integrative-structure of rectangular box-like shape, and function has been the effect of collecting dust.Waft in air the purpose that can not collect like this with regard to the chalk dust that has reached dust absorption blackboard eraser of the present utility model.

The beneficial effect of the dust absorption blackboard eraser of utility model is that the utility model is to solve chalk dust to waft in air, and the technical scheme that technical problem adopted that can not collect 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:

Second, because the right-hand member lead that has designed power pack in the technical scheme of dust absorption blackboard eraser of the present utility model is connected the lower end of switch, the lower end lead of switch is connected the left end of motor, the lower end of motor is threaded in the upper end of dust-absorbing fan, the lower end of dust-absorbing fan is threaded in the internal thread place, upper end of shoulder pad net, power pack links to each other by lead with switch, motor, dust-absorbing fan, constitute closed circuit, each component fixedly is nested in the inside of plastic housing, the structure that is combined into one is so the technical problem of easier solution power dust suction.

Second, be embedded in the upper end of collecting box owing to designed the lower end of plastic housing in the technical scheme of dust absorption blackboard eraser of the present utility model, the lower end of collecting box is bonded at the upper end of hairbrush, is combined into the integrative-structure of rectangular box-like shape, so the technical problem of dust is collected in easier solution.

(4) description of drawings:

Accompanying drawing provides the structural representation of dust absorption blackboard eraser of the present utility model:

Fig. 1: the overall structure schematic diagram that is dust absorption blackboard eraser of the present utility model;

The label declaration at each position in the schematic diagram:

1 plastic housing, 2 power packs, 3 switches, 4 motors

5 dust-absorbing fans, 6 shoulder pad nets 7 are collected box 8 hairbrush

(5) specific embodiment:

Below in conjunction with accompanying drawing, for realizing that solving chalk dust wafts in air, the optimal way of the technical scheme that the technical problem that can not collect is taked is described further to dust absorption blackboard eraser of the present utility model:

Its static structure: see also accompanying drawing: as shown in the figure, dust absorption blackboard eraser of the present utility model mainly is made of plastic housing 1, power pack 2, switch 3, motor 4, dust-absorbing fan 5, shoulder pad net 6, collection box 7, hairbrush 8.Its major part power pack 2, switch 3, motor 4, dust-absorbing fan 5, shoulder pad net 6 are selected for use by market.Its plastic housing 1 is rectangular hull shape shape, is material with plastics, through the thermoforming processing and manufacturing.Its collection box 7 is rectangular box-like shapes, is material with plastics, through the thermoforming processing and manufacturing.Its hairbrush 8 is elongate in shape, is material with plastics, through the machining manufacturing.

In shape, structure and combination thereof, the total essential features of dust absorption blackboard eraser of the present utility model and immediate prior art is: the root of hairbrush 8 is bonded in the lower surface of blackboard eraser, be combined into the integrative-structure of blackboard eraser shape, function has been the effect that erases the board.In shape, the structure and in conjunction with last, the dust absorption blackboard eraser of the present utility model technical characterictic different with immediate prior art is: the right-hand member lead of power pack 2 is connected the lower end of switch 3, the lower end lead of switch 3 is connected the left end of motor 4, the lower end of motor 4 is threaded in the upper end of dust-absorbing fan 5, the lower end of dust-absorbing fan 5 is threaded in the internal thread place, upper end of shoulder pad net 6, power pack 2 and switch 3, motor 4, dust-absorbing fan 5 links to each other by lead, constitute closed circuit, each component fixedly is nested in the inside of plastic housing 1, the structure that is combined into one, function is the effect of starting power dust suction.The lower end of plastic housing 1 is embedded in the upper end of collecting box 7, and the lower end of collecting box 7 is bonded at the upper end of hairbrush 8, is combined into the integrative-structure of rectangular box-like shape, and function has been the effect of collecting dust.

Below by using method, further set forth dust absorption blackboard eraser dynamic structure relation of the present utility model: in use, when needs erase the board, according to pneumatic power principle, at first install each component, open switch 3 and connect circuit, hairbrush 8 erases the board then, the chalk dust inspiration that dust-absorbing fan 5 turning handles are wiped of power by motor 4 is collected in the box 7 then again, thereby finishes the task of dust suction.Waft in air the technical scheme of the technical problem that can not collect like this with regard to the chalk dust of having realized dust absorption blackboard eraser of the present 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 mass production,, so just can realize the practical value and the economic worth of dust absorption blackboard eraser of the present utility model better with the demand of supply educational circles.
