Abstract

The invention discloses an automatic-sprinkler blackboard, comprising a blackboard body, a sliding frame, an eraser seat, an eraser, a collecting tank, a water storage cavity, a mandril and a control device, wherein the water storage cavity is arranged inside the eraser seat, while a permeable hole is arranged on bottom of eraser seat; permeable hole is provided with a membrane which consists of a pair of rubber sheets, whose middle parts are overlaid on each other. The mandril is arranged inside the collecting tank, with a penetrating hollow structure; the water-outlet component has a cavity, a posticum with aperture of 0.2-0.4 mm on front end and a circular frame thrusting forward on peripheral margin of the front end; the blackboard body support on end of the mandril, while the other end of mandril provides pressure on membrane, making the rubber sheet pairs separate with each other, besides, the water storage cavity is connected with water-outlet component through the mandril. The automatic-sprinkler blackboard realizes to erase chalk marks on the blackboard automatically.

Description

technical field [0001] The invention relates to a blackboard with automatic water spraying.
