Description
Technical field
This utility model relates to realia field, particularly to a kind of automatic blackboard eraser.
Background technology
Chalk dust not only can produce serious injury to human body, also the environment of surrounding can be caused the biggest destruction simultaneously.Through investigation display, what current most schools used be still is stained with mao matter by plastic casing or traditional blackboard that floss material is made is wiped.This easy blackboard eraser can cause dust to fly upward everywhere in wiping process, and the dust being detained after wiping is not easy cleaning very much, thus it is many unfavorable to bring to the teaching of teacher.In view of the various drawbacks of this blackboard eraser, occur in that the various blackboard eraser improving dedusting present situation in terms of different on the market.As improved its structure, improving its hairbrush material, even also have blackboard and blackboard eraser are made of one.Though these blackboard erasers are respectively arranged with advantage, but all do not have really be promoted on the market, through investigation, its main cause has: efficiency of dust collection is the lowest, technical to be the most well combined with practicality, cost is the highest, environmental protection and energy saving aspect shortcoming etc..
Utility model content
Technical problem to be solved in the utility model is to provide a kind of automatic blackboard eraser to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, this utility model provides following technical scheme: a kind of automatic blackboard eraser includes blackboard eraser main body and housing, described blackboard eraser main body includes Wiping mechanism and dust collection mechanism, described Wiping mechanism is positioned at the bottom of blackboard eraser main body, described Wiping mechanism includes motor, shaft coupling and round brush, described round brush is connected with motor by shaft coupling, described dust collection mechanism is positioned at above Wiping mechanism, including dust suction pump and the dust-collecting box that is connected with dust suction pump, the bottom of described blackboard eraser main body arranges air suction opening, described housing is provided above battery case, described battery case bottom arranges switch
Preferably, described housing arranges louvre.
Preferably, described blackboard eraser body top arranges arcuation groove.
Preferably, it is covered with one layer of soft rubber in described arcuation groove.
Preferably, described motor front end is provided with square groove, arranges non-hydrophilic lubricant grease in described square groove.
Above technical scheme is used to provide the benefit that: to the utility model discloses a kind of automatic blackboard eraser, on described housing, louvre is set, can allow motor radiating, it is made to have longer life, described blackboard eraser body top arranges arcuation groove, it is easy to hold force, one layer of soft rubber it is covered with in described arcuation groove, there is spring function, make palm more comfortable, described motor front end is provided with square groove, non-hydrophilic lubricant grease is set in described square groove, it is possible to prevent dust and the globule to enter motor, motor is played effectively protection, this automatic blackboard eraser has control effective, laborsaving, the advantage that automaticity is high, there is wide market prospect.
