Equipment for computer multimedia teaching

Abstract

The invention relates to the field of teaching equipment, in particular to equipment for computer multimedia teaching. The equipment comprises a bottom plate, a projection mechanism, a dust removing mechanism and a teaching blackboard. A lifting mechanism is arranged at the top of the bottom plate and comprises a mounting plate and two symmetrically-arranged material transferring assemblies. Two side plates are arranged at the bottoms of the two ends of the mounting plate correspondingly. The dust removing mechanism comprises a mist-spraying dust fall assembly and a dust collector. A teachingtable is arranged at the top of the bottom plate and internally provided with an accommodating cavity, and a computer is arranged in the accommodating cavity. The equipment for computer multimedia teaching has the beneficial effects that the projection angle of a projector can be automatically adjusted through the projection mechanism, a teacher does not need to conduct manual adjustment, and thusconvenience is brought to the teacher; and dust generated by using chalk can be automatically subjected to mist spraying and electrostatic dust removing treatment through the dust removing mechanism,so that the situation that large potential safety hazards are brought to the teacher and students due to the excessive dust is avoided.

Description

technical field [0001] The invention relates to the field of teaching equipment, in particular to equipment for computer multimedia teaching. Background technique [0002] Existing multimedia teaching equipment usually projects electronic courseware onto the screen of the podium through a projector. The content displayed by the projector can only be placed on a fixed screen, which cannot fully meet the observation needs of students from all angles in the classroom. It is cumbersome to manually adjust the projector at a high place; after teachers use chalk to write on the blackboard, it is easy to generate flying dust, especially in summer when excessive use of chalk will generate more dust, and teachers and students will inhale dust for a long time, which will be harmful to their health It will bring great influence to teachers and students. In the prior art, JP 2011-136422A discloses a multifunctional electronic blackboard, which integrates an adjustable projector and a bl...

[0002] Existing multimedia teaching equipment usually projects electronic courseware onto the screen of the podium through a projector. The content displayed by the projector can only be placed on a fixed screen, which cannot fully meet the observation needs of students from all angles in the classroom. It is cumbersome to manually adjust the projector at a high place; after teachers use chalk to write on the blackboard, it is easy to generate flying dust, especially in summer when excessive use of chalk will generate more dust, and teachers and students will inhale dust for a long time, which will be harmful to their health Bringing impact, bringing greater safety hazards to teachers and students

In the prior art, JP 2011-136422A discloses a multifunctional electronic blackboard, which integrates an adjustable projector and a blackboard. Since it is an electronic blackboard, the problem of dust generated by chalk is not considered. CN101508220A discloses The use of water nozzles to wipe the blackboard reduces the existence of dust, but it consumes a lot of water and needs to be dried automatically, which is inefficient. The environmental protection teaching blackboard disclosed by CN107364258A utilizes the characteristics of static electricity, and absorbs dust through the static net to avoid Dust is scattered everywhere, but it is passive vacuuming, and the adsorption space and adsorption capacity are limited, which is far from meeting the needs of avoiding dust pollution indoors. Moreover, there are resource waste problems caused by different dust levels in the prior art, which cannot be automatically Controllable dust control
