Blackboard with solar dust collection frame

Abstract

The invention relates to a blackboard with a solar dust collection frame, and belongs to the technical field of teaching equipment. The blackboard comprises a blackboard body, the frame, a first dustcollection device, a second dust collection device and a solar power generation device, wherein the frame is arranged on the periphery of the blackboard body, the frame is arranged to be a hollow closed channel, the first dust collection device comprises a first dust collector, a first dust suction main pipe, a first dust suction pipe and first dust suction holes, the second dust collection devicecomprises a second dust collector, a second dust collection main pipe, a second dust collection pipe and second dust collection holes, the solar power generation device comprises a solar cell and a storage battery, and the solar cell is installed outside a window. According to the blackboard with the solar dust collection frame, the first dust suction device and the second dust suction device arearranged so that dust on the surface of the blackboard can be sucked in all directions, the dust collection efficiency is high, and the dust collection is thorough; and the solar power generation device is arranged so that energy can be effectively saved, the physical health of students in a classroom can be protected against hurt, and good teaching environments in the classroom can be kept.

Description

technical field [0001] The invention relates to a blackboard with a solar dust suction frame, which belongs to the teaching equipment technology. Background technique [0002] The blackboard is one of the indispensable teaching equipment in the school teaching work. It is easy to write and provides great convenience for teachers to write blackboard writing on the spot in the classroom. However, when the blackboard is full of writing, it is necessary to erase the handwriting for the next class. When used by teachers, chalk dust flies during the erasing process, which seriously affects the health of students in the classroom and the teaching environment in the classroom. Some electric dust removal equipment is disclosed in the prior art, but there is still a phenomenon of poor dust suction effect. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a blackboard with a solar dust-absorbing frame, which can fully absor...
