The invention discloses a dust sucking environment-friendly blackboard eraser and belongs to the technical field of blackboard erasers. The dust sucking environment-friendly blackboard eraser comprises a handle, a shell, an adsorbing assembly, a main roller set, an auxiliary roller, felt cloth and a dust collecting assembly; one end of the shell is provided with an opening, and the handle is installed at the other end of the shell; the main roller set is rotationally installed in the shell and is parallel with the length direction of the opening of the shell; the auxiliary roller and the mainroller set are arranged in parallel; the felt cloth is annularly arranged and is encircled on the main roller set and the auxiliary roller; the dust collecting assembly comprises a dust collecting frame, a first electrostatic adsorbing piece, a second electrostatic adsorbing piece and an ash taking plate; the dust collecting frame is arranged in the shell and is located on the side where the mainroller set is screwed in; the dust collecting frame is provided with a long opening corresponding to the width of the felt cloth and faces the opening of the shell; the ash taking plate is arranged onthe side, opposite to the first electrostatic adsorbing piece, on the dust collecting frame; one end of the ash taking plate is fixed to the dust collecting frame; the other end of the ash taking plate makes contact with the felt cloth; and the width of the ash taking plate corresponds to that of the felt cloth. The dust sucking environment-friendly blackboard eraser is an electrostatic environment-friendly blackboard eraser which is simple and can prevent dust from falling in an electrostatic manner.
Description
technical field [0001] The invention relates to the technical field of blackboard erasers, in particular to a dust-absorbing environment-friendly blackboard eraser. Background technique [0002] According to relevant national reports, the statistical data in 1993 showed that the teachers and students of my country would inhale about 200 grams of chalk dust per person every year in class, and suffer from about 20% / year of respiratory tract, lung disease and cancer. This shows how great the health hazards of chalk dust are to teachers and students. At the same time, the flying chalk dust pollutes the personal hygiene of teachers and students very large, such as the flying chalk dust makes the collars, cuffs, hair, and bodies of teachers and students unable to do without its annoying shadow. [0003] Patent 201310103069.2 discloses a self-rotating roller dust-absorbing blackboard eraser, including a blackboard eraser and a control system, the motor is powered by a battery pack...
