Description
(1) technical field
The utility model relates to a kind of teaching aid, specifically a kind of blackboard eraser that has dust-absorbing function.
(2) background technology
Blackboard eraser is a kind of and blackboard is used the educational aid of wiping the chalk writing on the blackboard to scrape.Along with the development of society, the simple scraping structure that blackboard eraser has been made up of bristle and hair brush base progressively develops into the educational aid of multi-functionals such as having scraping and dust suction concurrently.But up to the present, because general applicability is not fine, so the blackboard eraser that has dust-absorbing function concurrently does not have penetration and promotion and comes.
(3) summary of the invention
Technical assignment of the present utility model is at the deficiencies in the prior art, and a kind of reasonable in design, compact conformation, easy to use, the blackboard eraser that has dust-absorbing function that pick-up performance is good are provided.
The technical scheme that its technical problem that solves the utility model adopts is:
The blackboard eraser that has dust-absorbing function, comprise bristle, hair brush base, dust absorption fan, fan shroud, motor, charge power supply, guard shield, handle, screen pack and dust storehouse, bristle is arranged on the upper surface of hair brush base, offer several dust through holes on the hair brush base, the lower surface of hair brush base is provided with fan shroud, be provided with the dust absorption fan that is connected with motor in the fan shroud, motor be connected with charge power supply and be arranged on guard shield that fan shroud is connected in, between motor and charge power supply, be provided with power switch, below guard shield, be provided with handle, top at fan shroud is provided with screen pack, bottom at fan shroud offers collection hole, and the below of fan shroud is provided with the dust storehouse and communicates by collection hole.
The above-mentioned blackboard eraser that has dust-absorbing function, its charge power supply has the charging plug of rotary and telescopic structure.
The above-mentioned blackboard eraser that has dust-absorbing function, its screen pack is made by the fine and close smooth cloth of multilayer.
Before the use, by charging plug charge power supply is charged earlier.During use, a hand-held handle, the another hand turns on the power switch, machine operation, drive dust absorption fan rotation produces suction, and the dust that utilizes bristle to swipe to get off enters in the fan shroud by the dust through hole on the hair brush base, air is discharged by the screen pack at fan shroud top, is isolated the collection hole of dust bottom fan shroud that gets off and enters in the dust storehouse.Finish using, open the dust storehouse, pour out dust and get final product.
A kind of blackboard eraser that has a dust-absorbing function of the present utility model compared with prior art, the beneficial effect that is produced is: reasonable in design, compact conformation, cheap, easy to use and pick-up performance is good, adaptability is strong.
