Description

Ash-collecting blackboard eraser

(1) technical field:

The utility model relates to ash-collecting blackboard eraser, divides the technical field that belongs to the group that the sucking chalk powder device is arranged by International Patent Classification (IPC) (IPC).

(2) background technology:

At present, the technology about group that the sucking chalk powder device is arranged existing and that once had need all be done very fruitful effort to ash-collecting 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 number is CN2216933Y, China Patent No. (ZL) is: No. 94218538.2 utility model title is the utility model patent of " blackboard wiper ", the technical scheme that is adopted, at group's technical elements that the sucking chalk powder device is arranged is a routine of great value invention, and it has solved the technical problem that can wipe the blackboard eminence easily effectively.But still have some deficits, but it also is difficult to solve dust suction, the easily fixed technical problem of holding.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of ash-collecting blackboard eraser.But to solve dust suction, the easy fixed technical problem of holding.

The new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is: ash-collecting blackboard eraser of the present utility model, mainly store place, blackboard wiper, dust catcher storeroom, dust catcher, air suction opening, lead by blackboard eraser lid, handle, switch, battery and constitute.

In shape, structure and combination thereof, the total essential features of ash-collecting blackboard eraser of the present utility model and immediate prior art is: the whole upper end fixed bonding of blackboard wiper is in the lower end of blackboard eraser lid, be combined into the integrative-structure of blackboard eraser shape, function has been the effect that erases the board.In shape, structure and combination thereof, the ash-collecting blackboard eraser of the present utility model technical characterictic different with immediate prior art is: the upper end of air suction opening is fixedly mounted on the lower end of dust catcher, the integral body that is installed in air suction opening is inserted in the inside of blackboard wiper, the terminals of dust catcher are connected the connector lug of power supply and switch with lead, wherein the overall fixed of dust catcher is placed in the dust catcher storeroom, the power supply fixed placement is in battery stores the place, be combined into OBL combining structure, but function has been the effect of dust suction.The upper surface of blackboard eraser lid is fixedly mounted on the two ends of handle, and the upper surface of handle is fixedly mounted on the integral body of switch, is combined into the combining structure of arcuate zone cell body shape, and function has been the fixed effect of easy holding.But so just reached ash-collecting blackboard eraser dust suction of the present utility model, easily the fixed purpose of holding.

But the beneficial effect of the ash-collecting blackboard eraser of utility model is the utility model is to solve dust suction, and easily the fixed technical scheme that technical problem adopted of holding has been compared two place's advantage and improvement with existing with the technology about group that the sucking chalk powder device is arranged that once had:

First, because the upper end of having designed air suction opening in the technical scheme of ash-collecting blackboard eraser of the present utility model is fixedly mounted on the lower end of dust catcher, the integral body that is installed in air suction opening is inserted in the inside of blackboard wiper, the terminals of dust catcher are connected the connector lug of power supply and switch with lead, wherein the overall fixed of dust catcher is placed in the dust catcher storeroom, the power supply fixed placement is combined into OBL combining structure in battery stores the place, so but the technical problem of easier solution dust suction.

Second, because the upper surface that has designed the blackboard eraser lid in the technical scheme of ash-collecting blackboard eraser of the present utility model is fixedly mounted on the two ends of handle, the upper surface of handle is fixedly mounted on the integral body of switch, be combined into the combining structure of arcuate zone cell body shape, so the fixed technical problem of the easy holding of easier solution.

(4) description of drawings:

Accompanying drawing provides the structural representation of ash-collecting blackboard eraser of the present utility model:

7 dust catchers, 8 air suction openings, 9 leads

(5) specific embodiment:

Below in conjunction with accompanying drawing, but ash-collecting blackboard eraser of the present utility model is solved dust suction for realization, the optimal way of the technical scheme that the easy fixed technical problem of holding is taked is described further:

Its static structure: see also accompanying drawing: as shown in the figure, ash-collecting blackboard eraser of the present utility model mainly stores place 4, blackboard wiper 5, dust catcher storeroom 6, dust catcher 7, air suction opening 8, lead 9 by blackboard eraser lid 1, handle 2, switch 3, battery and constitutes.Its major part switch 3, battery store place 4, blackboard wiper 5, dust catcher storeroom 6, dust catcher 7, lead 9 and are selected for use by market.Its blackboard eraser lid 1 is rectangular interior trough of belt shape, is material with plastics, through the machining manufacturing.Its handle 2 is arcuate zone cell body shapes, is material with plastics, through the machining manufacturing.Its air suction opening 8 is elongate in shape, is material with plastics, through the machining manufacturing.

In shape, structure and combination thereof, the total essential features of ash-collecting blackboard eraser of the present utility model and immediate prior art is: the whole upper end fixed bonding of blackboard wiper 5 is in the lower end of blackboard eraser lid 1, be combined into the integrative-structure of blackboard eraser shape, function has been the effect that erases the board.In shape, structure and combination thereof, the ash-collecting blackboard eraser of the present utility model technical characterictic different with immediate prior art is: the upper end of air suction opening 8 is fixedly mounted on the lower end of dust catcher 7, the integral body that is installed in air suction opening 8 is inserted in the inside of blackboard wiper 5, the terminals of dust catcher 7 are connected the connector lug of power supply and switch 3 with lead 9, wherein the overall fixed of dust catcher 7 is placed in the dust catcher storeroom 6, the power supply fixed placement is in battery stores place 4, be combined into OBL combining structure, but function has been the effect of dust suction.The upper surface of blackboard eraser lid 1 is fixedly mounted on the two ends of handle 2, and the upper surface of handle 2 is fixedly mounted on the integral body of switch 3, is combined into the combining structure of arcuate zone cell body shape, and function has been the fixed effect of easy holding.

Below by using method, further set forth ash-collecting blackboard eraser dynamic structure relation of the present utility model: in use, in the time of the needs dust suction, according to physical principle, at first dust catcher 7 is fixedly mounted on blackboard eraser and covers in the groove of 1 inside, then lead 9 is connected, open switch 3 more then and make dust catcher 7 work, by air suction opening 8 dust is sucked, thereby finish the task of dust suction.But so just realized ash-collecting blackboard eraser dust suction of the present utility model, the technical scheme of the technical problem that easy holding is fixed.

Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of stationery factory, take to produce by batch in a large number,, so just can realize the practical value and the economic worth of ash-collecting blackboard eraser of the present utility model better with the demand of supply educational circles.
