Dustless electric blackboard

Abstract

The invention discloses a dustless electric blackboard. The dustless electric blackboard comprises a machine body, and a first cavity formed in the machine body; a second cavity is arranged above thefirst cavity; a first rotating shaft, extending left and right, is arranged in the first cavity; the tail end of the right side of the first rotating shaft is in power connection with a motor slidingly arranged in the right side end wall of the first cavity; a first bevel gear is fixedly arranged at the tail end of the left side of the first rotating shaft; and a second rotating shaft, extending up and down, is rotationally arranged between the first cavity and the second cavity. The equipment is simple in structure, uses an electric energy driving mechanical structure for realizing automaticswitching of the blackboard as needed, realizes automatic wiping without needing manual operation, and meanwhile, uses a centrifugal pump for extracting dust generated in wiping of the blackboard to prevent the influence on the health of teaching staff and students by a lot of dust; and through switching of two blackboards, the effective writing area of the teaching staff is guaranteed, and meanwhile, the automation degree and the practicability of the equipment are improved.

Description

technical field [0001] The invention relates to the field of education and office work, in particular to a dust-free electric blackboard. Background technique [0002] Although with the large investment in education funds, multimedia teaching methods continue to increase, but the traditional blackboard writing is still irreplaceable, but the traditional blackboard writing is written with chalk, and when the educational staff or students wipe the blackboard, a large amount of dust will be generated, causing education staff and The physical health of students is affected, and the burden on educational staff and students is also increased, so a low-cost device is needed to solve such problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dust-free electric blackboard, which can solve the above-mentioned problems in the prior art. [0004] The present invention is achieved through the following technical soluti...
