Of the present utility model without dust Combined blackboard eraser, by the following technical solutions:
This blackboard eraser, comprise water storage cylinder, piston rod and cleaning head, cleaning head is arranged on one end of water storage cylinder, piston rod is arranged in water storage cylinder, and stretched out by the other end, cleaning head is provided with xerotripsis body, hole for water spraying and wet rubbing body, and the two ends of hole for water spraying are communicated with wet rubbing body with water storage cylinder respectively, and xerotripsis body and wet rubbing body are respectively in the both sides of hole for water spraying.
Water filling in water storage cylinder, promote piston rod and make wet rubbing body moistening, first by moistening wet rubbing body wiping chalk writing, adsorbing powder dust, on wet rubbing body, can not cause and fly upward.Then the wiping one time again of xerotripsis body is used, by the water stain wiped clean on blackboard.
The utility model structure is simple, easy to use, both chalk writing thoroughly can have been put in order clean, and can not fly up again, polluting, ensure that the physical and mental health of academics and students to having dust.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model without dust Combined blackboard eraser.
Wherein: 1, water storage cylinder, 2, piston rod, 3, wet rubbing body, 4, hole for water spraying, 5, xerotripsis body.
Detailed description of the invention
Fig. 1 gives the structure of the utility model without dust Combined blackboard eraser, and mainly comprise water storage cylinder 1, piston rod 2 and cleaning head, cleaning head is arranged on one end of water storage cylinder 1, and piston rod 2 is arranged in water storage cylinder 1, and is stretched out by the other end.Cleaning head is provided with xerotripsis body 3, hole for water spraying 4 and wet rubbing body 5, and hole for water spraying 4 is communicated with water storage cylinder 1, and hole for water spraying 4 is positioned at centre, and xerotripsis body 3 and wet rubbing body 5 are respectively in the both sides of hole for water spraying 4, and hole for water spraying 4 is communicated with wet rubbing body 5, and isolates with xerotripsis body 3.All with the soft cloth absorbed water of wiping on xerotripsis body 3 and wet rubbing body 5.
