Description
Technical field
The utility model relates to a kind of blackboard eraser, particularly relates to a kind of electronic without the synchronous dust absorption blackboard eraser of dead angle wiping.
Background technology
Blackboard eraser is requisite teaching aid in teaching process, needs the hand-held blackboard eraser of teacher to utilize the reciprocal wiping of manpower in use, wastes time and energy; The a large amount of dust meeting serious harm teachers produced in wiping process are healthy, the data display of Center for Disease Control of China, the illness rate of the teachers in primary and middle schools' asthma worked more than 5 years is 43%, the illness rate of rhinitis is 39%, the illness rate of pneumoconiosis is 11.76%, bronchitic illness rate is 8%.
Authorization Notice No. is that the Chinese patent of CN203126295 U discloses one " electric blackboard eraser ", comprise housing, 2 motorized pulleys, the hairbrush be wrapped in outside cylinder, dust suction air inlet, dust receiver and handles, it achieve electric erasing blackboard and dust suction, but can not effective erasing chalk writing, can not erasing blackboard edge and eminence writing.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of electronic without the synchronous dust absorption blackboard eraser of dead angle wiping.
The technical scheme in the invention for solving the above technical problem is: a kind of electronic without the synchronous dust absorption blackboard eraser of dead angle wiping, it is characterized in that comprising blackboard eraser body, hairbrush, suction port, power switch, handle, motor, impeller and storage dirt bag.Described hairbrush totally 4, is arranged on corner, blackboard eraser body front respectively, and described hairbrush edge all protrudes from blackboard eraser body; Described suction port is arranged at blackboard eraser body front; Described power switch is arranged on handle; Described handle is connected to the blackboard eraser body back side, its adjustable in length; Described motor, impeller and storage dirt bag are all arranged at blackboard eraser body inside.
Compared with prior art, the beneficial effects of the utility model are: 1. blackboard eraser electric erasing blackboard, and do not need to utilize the reciprocal wiping of manpower, alleviate teacher's hand labour intensity, time saving and energy saving, operating efficiency is high.2. synchronous automatic dust absorption when erasing the board, avoids chalk dust to fly away everywhere, is conducive to teacher healthy.3. hairbrush edge protrudes from beyond blackboard eraser body, erasable blackboard edge writing; Utilize adjustable in length handle, erasable blackboard eminence writing, thus realize the object without dead angle wiping.The utility model structure is simple, is suitable for practical application.

Detailed description of the invention
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
As Fig. 1,2,3, the utility model is a kind of electronic without the synchronous dust absorption blackboard eraser of dead angle wiping, comprises blackboard eraser body 1, hairbrush 2, suction port 3, power switch 4, handle 5, motor, impeller and storage dirt bag.Described hairbrush 2 is totally 4 i.e. hairbrush 2.1, hairbrush 2.2, hairbrush 2.3 and hairbrush 2.4, and be arranged on corner, blackboard eraser body 1 front respectively, its edge all protrudes from blackboard eraser body 1; Described suction port 3 is arranged at blackboard eraser body 1 front; Described power switch 4 is arranged on handle 5; Described handle 5 is connected to blackboard eraser body 1 back side, its adjustable in length; It is inner that described motor, impeller and storage dirt bag are all arranged at blackboard eraser body 1.
Operation principle: power-on switch 4, motor work impeller is rotated, near suction port 3, form negative pressuren zone; Hairbrush 2.1 turns clockwise simultaneously, and hairbrush 2.2 is rotated counterclockwise, and produces larger frictional force between hairbrush and blackboard surface, and chalk writing is wiped, and chalk dust is brought to suction port 3 and sucks storage dirt bag; Hairbrush 2.3 turns clockwise, and hairbrush 2.4 is rotated counterclockwise, and is brought to suction port 3 sucks storage dirt bag by the chalk dust wiped.The edge of hairbrush 2.1 ~ 2.4 all protrudes from blackboard eraser body 1, therefore erasable blackboard edge writing.The length of regulating handle 5, hand-held handle 5 moves on blackboard, can erasing blackboard eminence chalk writing.After using a period of time, storage dirt bag is taken off, concentrate cleaning chalk dust.
