Background technology

Blackboard eraser is that one of common tool in teaching, school or enterprise typically require when using black board teaching or record and to the vestige of wiping on blackboard thus realize again writing by blackboard eraser.Traditional blackboard is wiped in use, manual operation is needed to make it wipe the vestige on blackboard, but, if user is shorter, then it then can be relatively difficult when erasing the board, and when its people use blackboard eraser wiping written trace, often causing chalk dust to fly upward in classroom, the chalk dust descended slowly and lightly can be sucked by operator, and dust enters respiratory tract, enter human lung, health is existed hidden danger.Therefore, these problems occurred in use based on current blackboard eraser, study a kind of blackboard eraser that can solve these problems, there is important practical significance.

Notification number CN204383023U discloses the multifunctional blackboard eraser of a kind of automatic dust absorption, including blackboard eraser body, spongy layer, vacuum cleaner and accumulator；Described spongy layer is located at blackboard eraser body upper surface；Described vacuum cleaner and accumulator are equipped with in blackboard eraser body, and storage battery connects vacuum cleaner；Described blackboard eraser body side is provided with electronic clock and switch key, storage battery connects electronic clock, switch key accesses the power supply circuits between accumulator and vacuum cleaner, but this blackboard eraser cannot meet classmate or teacher's wiping to blackboard of different height, and the absorption relying solely on spongy layer can not more efficient comprehensive wiping chalk dust.

Utility model content

In view of this, the purpose of this utility model is for the deficiencies in the prior art, it is provided that a kind of scalable, can regulate blackboard eraser height, inhale chalk dust effect collect substantially, timely erase the board during produced chalk dust the blackboard eraser that prevents chalk dust from splashing.

For reaching above-mentioned purpose, this utility model by the following technical solutions:

nullA kind of blackboard eraser，Including blackboard eraser body and handle，Described blackboard eraser body is included wiper successively by front to the back side、Sponge、Vibrating plate、Vacuum cleaner、Battery case and blackboard eraser bottom，Described wiper and sponge arrange multiple through hole being interconnected，Described vibrating plate includes the first vibrating plate and the second vibrating plate，Between described first vibrating plate and the second vibrating plate, dust absorption passage is set，Described dust absorption passage is connected with described vacuum cleaner，Described blackboard eraser body side arranges dust box，Described dust box communicates with vacuum cleaner，In the middle part of described blackboard eraser bottom, groove is set，Described blackboard eraser bottom both sides arrange multiple finger groove，Described groove is provided with expansion link，Described handle is fixing with blackboard eraser bottom to be connected，Described handle arranges the first switch and second switch，Described first switch and vibrating plate、Battery case is sequentially connected electrically，Described second switch and vacuum cleaner、Battery case is sequentially connected electrically.

Preferably, described sponge upper surface arranges drainage screen.

Preferably, described expansion link includes two sections of concentric hollow cylinders, and internal layer cylinder one end is fixing with groove to be connected, and the other end is connected with outer layer cylindrical slid.

Preferably, in described battery case, chargeable storage is set.

Preferably, described blackboard eraser body being provided with charging inlet, described charging inlet electrically connects with battery case.

The beneficial effects of the utility model are:

null1. this utility model arrange vacuum cleaner can collect timely erase the board during produced chalk dust flying dust，Prevent chalk dust from splashing，It is operated with manual switches，Control more flexible，Thus be prevented effectively from and erase the board to student or the threat of teacher's health，Expansion link can regulate the use height of blackboard eraser，The classmate of the different height of guarantee or teacher can clip the top half of blackboard，The not used time，May be collapsible in blackboard eraser，Do not affect the overall use of blackboard eraser，Arranging of vibrating plate can chalk dust on significantly more efficient removing blackboard，When blackboard eraser is in the top half of blackboard，Exert oneself due to bad，The now vibrations of vibrating plate just can more preferable blackboard wiping，Dust absorption passage is reserved between first vibrating plate and the second vibrating plate，The chalk dust that vibrations wiping or sponge friction wiping are got off can preferably be absorbed by vacuum cleaner.

2. this utility model wiper and sponge arrange multiple through hole being interconnected, the vibrations dust removing effects that vibrations bring is also ensure that while sponge damping vibration sheet shockproofness to a certain extent, multiple through holes add the vacuum cleaner absorption to chalk dust, preventing owing to sponge and wiper entirety permeability be not strong, hole is less and blocks the vacuum cleaner absorption to chalk dust.

3. this utility model blackboard eraser bottom arranges multiple finger groove, facilitates finger force so that more firm stable during use, and power supply uses chargeable storage, and is provided with charging inlet, adds recycling number of times and the service life of blackboard eraser.
