At present, in the teaching process of China school, what still extensively adopt is the teaching method of being write on blackboard with chalk by teacher, the blackboard eraser that is adopted still usefulness be the iron sheet box structure of traditional band felt, when blackboard wiping, dust from flying in the classroom easily by in people's suction body, works the mischief to teachers and students' health.For this reason, people improve traditional blackboard eraser, have invented the blackboard eraser of various band dust exhaust apparatuses, but because its structure is reasonable not enough, pick-up performance is not satisfactory, fails to be applied.For example:
Granted publication number discloses a kind of dust absorption blackboard eraser in the Chinese patent of CN2579679Y, by cover body, exhaust fan, the motor of wiping board, double as pedestal, advance the dirt passage, go out the dirt passage, dust filtration device forms; The wiping board and the exhaust fan that are arranged in the cover body are coaxial, the shared drive motors of exhaust fan and wiping board, dust filtration device is arranged on the tubaeform reverse bag in the no end at exhaust fan rear, between wiping board cover body and exhaust fan by advancing the dirt channel connection, between exhaust fan and dust filtration device by going out the dirt channel connection.
Adopt such technology certainly to realize the purpose of dust absorption blackboard eraser, but with the tubaeform reverse bag in the no end as dust filtration device, be dry dust removal, still have dust, filter dirt is undesirable; Blackboard eraser and blackboard are not an integral body, and it is convenient not enough to use.
The utility model content
Be the existing weak point of the blackboard eraser that overcomes prior art, the utility model provides a kind of wet dust removal, pick-up performance good; Blackboard eraser and blackboard are an integral body, use ash-collecting blackboard eraser more easily.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of ash-collecting blackboard eraser comprises wiping board, wiping board cover body, exhaust fan, pedestal, exhaust fan drive motors, wiping board drive motors, advances the dirt passage, goes out dirt passage, dust filtration device; The wiping board that is arranged in the wiping board cover body is connected with the wiping board drive motors, and exhaust fan is connected with the exhaust fan drive motors and all is arranged on the pedestal with dust filtration device; Between exhaust fan and dust filtration device by going out the dirt channel connection, between wiping board cover body and exhaust fan by advancing the dirt channel connection; It is characterized in that: also comprise the track-type facilities that connects pedestal and blackboard; Dust filtration device is a water tank, and the outlet that goes out the dirt passage is arranged on the appropriate location of water surface below in the water tank; The dirt passage that advances that is arranged between wiping board cover body and exhaust fan is a soft pipeline.
Described track-type facilities is to be provided with a traverse rod above blackboard; Traverse rod connects pedestal by the traverse rod roller that is arranged on the traverse rod.
Described wiping board be no less than one be located at disk in the wiping board cover body and the wiping board drive motors of respective numbers is connected, one side is provided with reasonable quantity, arranges suitable thorn-like and wipe thorn on the disk, the center of disk another side is connected with wiping board drive motors accordingly.
It is described that to go out the dirt passage be that pedestal is provided with a cylindrical shape exhaust fan chamber, one of exhaust fan chamber with advance the dirt channel connection, the other end is provided with wireway and is connected to water tank.
Described wireway is to stretch into the water from water tank water surface top, and the wireway opening is located at the underwater.
The beneficial effects of the utility model are: because dust filtration device comprises a water tank, the outlet that goes out the dirt passage is arranged on water surface below in the water tank, adopt wet dust removal, pick-up performance is good; Because be provided with the track-type facilities that connects cover body and blackboard, blackboard eraser and blackboard are an integral body, use more convenient; Can improve classroom environment effectively, reduce dust pollution, the assurance teachers and students' is healthy.
