Abstract

The invention discloses a dust-free environment-friendly blackboard eraser, which comprises an eraser housing and an eraser cotton main body; the eraser cotton main body is arranged below the eraser housing; the eraser cotton main body is in transmission connection with the eraser housing; an atomizing nozzle is arranged below the eraser housing to penetrate through the eraser housing; and a pressing pump is arranged inside the eraser housing and is fixedly connected in the eraser housing. According to the dust-free environment-friendly blackboard eraser, a transmission block is arranged belowthe eraser cotton main body and provided with a piston, one end of the piston is fixedly connected with the transmission block, a water suction pipe is arranged, when a blackboard is erased, the eraser cotton main body is stressed to move the transmission block downwards and the piston thus generates air pressure difference in the pressing pump, and the water suction pipe pressurizes electrostatic liquid in a liquid storage cavity into an atomizing spray head, each action causes the blackboard eraser to continuously spray water mist under the pressure during work, and small water droplets andchalk dust are bonded together, so that the chalk dust falls under the gravity, and the health of a user is prevented from being endangered by the dust.

Description

technical field [0001] The invention relates to the technical field of dust-free and environment-friendly, in particular to a dust-free and environment-friendly blackboard eraser. Background technique [0002] The so-called blackboard eraser is used to write on it with specific writing materials such as chalk. The blackboard is mostly black, dark green, white or beige, and the chalk is mostly white. Using it can make teachers and students wipe off the chalk writing easily and conveniently. According to preliminary statistics, only the potential sales volume in the school market is more than 10 million units, plus The market potential is huge for the needs of places such as homes or offices. [0003] However, the design of the existing blackboard eraser is not reasonable enough, and the efficiency of the existing blackboard eraser is low. When the blackboard is being wiped, dust is caused to fly, and a layer of white chalk dust is often left on the teacher's hands, sleeves, ...
