Problems solved by technology

[0003] However, although the current multimedia all-in-one machine can use the multimedia display screen and the blackboard in combination, when the multimedia display screen is used up, the sliding blackboard is usually slid to close directly, so that the multimedia display screen will be enclosed in the frame. As a result, the heat on the multimedia display screen cannot be effectively dissipated, thereby reducing the service life of the multimedia display screen, and the heat dissipation holes on the current multimedia display screen are easy to attach a large amount of chalk dust and other sundries, and these chalk dust Such sundries cannot be cleaned automatically, thereby reducing the ventilation effect at the cooling holes on the multimedia display

Abstract

The invention provides a multimedia teaching device based on a middle vocational and higher vocational joint course, and relates to the technical field of teaching devices. The left end and the right end of the front side in the frame body are each fixedly connected with a fixed blackboard, the upper end face and the lower end face of the front side in the frame body are each provided with a sliding groove, and two sliding blackboards are slidably connected between the two sliding grooves in a bilateral symmetry mode. Through cooperation of the pressing switch and the air conveying mechanism, heat dissipated by heat dissipation holes in the multimedia display screen can be discharged in time, the service life of the multimedia display screen is prolonged, through arrangement of the cleaning mechanism and the sweeping part, blocked chalk dust and other sundries can be automatically cleaned, and the practicability is high. The problems that after an existing multimedia display screen is used up, a sliding blackboard is usually and directly closed in a sliding mode, so that heat on the multimedia display screen cannot be dissipated, and the service life of the multimedia display screen is shortened are solved.

Description

technical field [0001] The invention relates to the technical field of teaching devices, in particular to a multimedia teaching device for connecting courses based on secondary and higher vocational education. Background technique [0002] Multimedia teaching means that in the teaching process, according to the characteristics of teaching objectives and teaching objects, through teaching design, rationally select and use modern teaching media, and organically combine them with traditional teaching methods. In the process of multimedia teaching, multimedia integration is usually used. machine. [0003] However, although the current multimedia all-in-one machine can use the multimedia display screen and the blackboard in combination, when the multimedia display screen is used up, the sliding blackboard is usually slid to close directly, so that the multimedia display screen will be enclosed in the frame. As a result, the heat on the multimedia display screen cannot be effecti...
