Purpose of the utility model is realized as follows: a kind of blackboard brush, including box body, felt, handle, support plate, liquid Body bottle, minim pipette, stereoplasm tube and flow control switch；Box body is hollow rectangular parallelepiped structure, is spliced by hard material；Box body Upper and lower surfaces opposite position is respectively provided with multiple equally distributed first through hole, and corresponding two first through hole are used up and down Stereoplasm tube is attached；Felt is fixedly connected on box body lower surface；The bottom of support plate is fixedly connected on cartridge upper surface, support It is equipped with flow control switch in the middle part of plate, is equipped with liquid bottles at the top of support plate；Liquid bottles bottom is equipped with multiple second through-holes；Minim pipette One end pass through the second through-hole of liquid bottles bottom and extend into inside liquid bottles, the other end passes through on flow control switch and box body The stereoplasm tube on surface is correspondingly connected with；Flow control switch is made of sliding slot and pulley；Handle both ends are fixedly connected on table on box body Face, wherein one end is close to the marginal position of cartridge upper surface, and the other end is equipped with oblong openings.

Further, support plate is two, and the two structure is identical and is placed in parallel, the bottom of support plate and cartridge upper surface It is fixedly connected at an angle, angular range is 30 to 60.

Further, liquid bottles are made of body and bottle cap, and liquid bottles two sides of the bottom are connected with two support plates respectively, liquid The central axis of body bottle is parallel with cartridge upper surface.

Further, liquid bottles are plastic material.

Further, minim pipette quantity is consistent with the quantity of cartridge upper surface first through hole, the second through-hole of liquid bottles bottom, First through hole is evenly distributed on four angles and center of cartridge upper surface.

Further, box body and support plate are hard material.

Further, box body and support plate are three-ply board.

Due to carrying out above-mentioned technical proposal, allows for the utility model and have following the utility model has the advantages that structure is simple, operation side Just, manufacturing cost is cheap, and the felt soaked by box body bottom can scrub blackboard, while the liquid on felt can be prevented Only chalk dust is spread, and is substantially reduced the chalk ash content in air, is effectively kept classroom neat and tidy, to protect teachers and students' body Body health.
