Abstract
The utility model relates to a blackboard capable of carrying out erasure automatically, wherein the blackboard comprises an erasing device, a pouring mist device and a blowing device. The erasing device utilizes a motor to drive an erasing roll by a chain to make reciprocating motions, wherein the erasing roll is slided on the backboard by pulleys. The pouring mist device is formed by connection of a spraying pipe and a water pump in a water pool; the spraying pipe is arranged above the blackboard and orifices are arranged at an interval. The blowing device is arranged at the side of the backboard and is formed by connection of a blower and a horn-shaped air opening. According to the blackboard capable of carrying out erasure automatically provided by the utility model, the existing blackboard is improved by mechanical and electrical equipment to realize automatic erasing of the blackboard and effectively prevent dust generation; the provided blackboard has a rapid and convenient erasing effect, thereby effectively relieving physical troubleness of teachers and students due to blackboard erasing and saving time for lecturing of teachers.
Description
Technical field
