1. by the setting of dirt case and blower fan, substantial amounts of dust can be adsorbed, passes through setting at least two blower fan
Put, it is ensured that sufficient air quantity, while by the setting of Universal pipe, can arbitrarily change the position of inlet scoop on Universal pipe,
The best position of adsorption effect is obtained according to actual conditions；, can be when detecting dust, certainly by the setting of dust sensor
Dynamic control blower fan is opened, while by the setting of independent current source, the drawbacks of eliminating power-limited connection, and independent current source uses
Can directly it be changed when finishing.
2. by the setting of attractive gel, the adsorption effect of blackboard eraser can be further lifted, while by attractive gel
Middle setting metal derby, then by the setting of electromagnet, electromagnet adsorbing metal block can be used, and then attractive gel is adsorbed
In bottom portion of groove, when needing to be changed, electromagnet is closed, attractive gel is tear-away changed.
3. present invention installation is light, changes conveniently, without specially safeguard；Simple laborsaving, convenient and efficient is used, will not
Caused by the factors such as height, blackboard position part blackboard eraser not, wipe the situation such as unclean；Compared with existing frequently-used common holding
Blackboard eraser, it has the advantages of time saving quick, dust is few, clean environment firendly again;Product function is rationally and practical, is readily produced and pushes away
Extensively.
