Description

Dust-free black board eraser

(1) technical field:

The utility model relates to dust-free black board 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 dust-free black board 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, it also is difficult to solve automatic dust absorption, the technical problem of collecting dust.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of dust-free black board eraser.To solve automatic dust absorption, the technical problem of collecting dust.

The new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is: dust-free black board eraser of the present utility model mainly is made of framework, skylight, dividing plate, end socket plug, base plate, sweep-up pipe, dust catcher, switch, power supply, hole, blackboard wiper, lead.

In shape, structure and combination thereof, the total essential features of dust-free black board eraser of the present utility model and immediate prior art is: the integral adhesive of blackboard wiper is at the lower surface of base plate, the upper surface of base plate is fixedly connected on the lower surface of framework, 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 dust-free black board eraser of the present utility model technical characterictic different with immediate prior art is: portal with mechanical means processing in the centre of base plate, one of them hole is just in time to the suction port place at dust catcher, the integral body of dust catcher is nested in the left side of framework, the terminals lead of dust catcher is connected on power supply, the switch, form closed circuit, be combined into the combining structure of dust catcher circuitry shapes, function has been the effect of automatic dust absorption.The interstitial hole of dividing plate is inserted with sweep-up pipe in the dust mouth of dust catcher, and dust is collected on the right side of dividing plate, be combined into rectangular in the middle of the combining structure of band partition shape, function has been the effect of collection dust.So just reached dust-free black board eraser of the present utility model for realizing automatic dust absorption, the purpose of collecting dust.

The beneficial effect of the dust-free black board eraser of utility model is that the utility model is to solve automatic dust absorption, and the technical scheme that technical problem adopted of collecting dust 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 having designed the centre of base plate in the technical scheme of dust-free black board eraser of the present utility model portals with mechanical means processing, one of them hole is just in time to the suction port place at dust catcher, the integral body of dust catcher is nested in the left side of framework, the terminals lead of dust catcher is connected on power supply, the switch, form closed circuit, be combined into the combining structure of dust catcher circuitry shapes, so the technical problem of easier solution automatic dust absorption.

Second, because the interstitial hole of dividing plate is inserted in the dust mouth of having designed dust catcher in the technical scheme of dust-free black board eraser of the present utility model with sweep-up pipe, dust is collected on the right side of dividing plate, is combined into the combining structure of rectangular middle band partition shape, so the technical problem of dust is collected in easier solution.

(5) specific embodiment:

Below in conjunction with accompanying drawing, for realizing solving automatic dust absorption, the optimal way of the technical scheme that the technical problem of collection dust is taked is described further to dust-free black board eraser of the present utility model:

Its static structure: see also accompanying drawing: as shown in the figure, dust-free black board eraser of the present utility model mainly is made of framework 1, skylight 2, dividing plate 3, end socket plug 4, base plate 5, sweep-up pipe 6, dust catcher 7, switch 8, power supply 9, hole 10, blackboard wiper 11, lead 12.Its major part sweep-up pipe 6, dust catcher 7, switch 8, battery 9, blackboard wiper 11, lead 12 are selected for use by market.Its framework 1, base plate 5 are oblong-shapeds, are material with plastics, through the machining manufacturing.Its skylight 2, dividing plate 3 are oblong-shapeds, are material with plastics, through the machining manufacturing.Its end socket plug 4 is truncated conical shape, is material with plastics, through the machining manufacturing.

In shape, structure and combination thereof, the total essential features of dust-free black board eraser of the present utility model and immediate prior art is: the integral adhesive of blackboard wiper 11 is at the lower surface of base plate 5, the upper surface of base plate 5 is fixedly connected on the lower surface of framework 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 dust-free black board eraser of the present utility model technical characterictic different with immediate prior art is: the centre of base plate 5 portals 10 with mechanical means processing, one of them hole 10 is just in time to the suction port place at dust catcher 7, the integral body of dust catcher 7 is nested in the left side of framework 1, the terminals lead 12 of dust catcher 7 is connected on power supply 9, the switch 8, form closed circuit, be combined into the combining structure of dust catcher circuitry shapes, function has been the effect of automatic dust absorption.The dust mouth of dust catcher 7 uses sweep-up pipe 6 to insert the interstitial hole of dividing plates 3, and dust is collected on the right side of dividing plate 3, is combined into the combining structure of rectangular middle band partition shape, and function has been the effect of collection dust.

Below by using method, further set forth dust-free black board eraser dynamic structure relation of the present utility model: in use, when the needs automatic dust absorption, when collecting dust, according to physical principle, at first with dust catcher 7 fixed placement in the inside left of framework 1 and connect circuit, open switch 8 then and make dust catcher 7 work, dust 10 is inhaled into along the hole, and dust is deposited the powder place by the right side that sweep-up pipe 6 leaves framework 1 in then again, thereby finish automatic dust absorption, collect the task of dust.So just realized that dust-free black board eraser of the present utility model is for solving automatic dust absorption, the technical scheme of the technical problem of collection dust.

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