Safe and reliable teaching device based on communication network

Abstract

The invention relates to a safe and reliable teaching device based on a communication network. The teaching device comprises a host, a vertical plate, a display screen, a camera, a broadcaster, an anti-radiation film and a cleaning device; the cleaning device comprises a sealing shell, a cleaning mechanism and a sealing mechanism. The cleaning mechanism comprises a cleaning box, a liquid conveyingpipe, a liquid outlet pipe, a spraying pipe, a fixing pipe, a reciprocating plate, a reciprocating assembly and a plurality of nozzles. The sealing mechanism comprises a sealing plate, a driving assembly, a rack, a first motor, a gear, a support and a cleaning assembly. According to the safe and reliable teaching device based on the communication network, the eyes of a user observing the displayscreen are protected through the anti-radiation film, and the display screen is dust-free; a roller can be used for driving the anti-radiation film to rotate, after the cleaning mechanism sprays the cleaning liquid, the cleaning assembly in the sealing mechanism is matched for cleaning, and after cleaning is completed, the sealing plate seals the opening, so that dustproof protection of the anti-radiation film at the cleaned part is realized, and the practicability of the equipment is improved.

Description

technical field [0001] The invention relates to the field of communication technology equipment, in particular to a safe and reliable teaching device based on a communication network. Background technique [0002] In the current teaching communication process, whether it is short-distance education or distance education, teachers and students are no longer completing teaching face-to-face in many cases, but teachers and students realize the teaching process by exchanging images and sounds through their respective terminal devices. Specifically, the image and sound of the teacher during the teaching process can be collected as a teaching video through his terminal device, and the teaching video is sent to the student's middle terminal device through the teacher's terminal device, so that the students can play the teaching video through their terminal device Video Watch and hear images and sounds of the teacher as they teach. It can be seen that, in order to realize the inter...

Problems solved by technology

[0003] When teachers and students use these teaching devices with communication functions, they inevitably need to observe the display screen. After watching the display screen in front of the device for a long time, due to the glare and radiation emitted by the screen, and long-term near-sighted work, it is very easy to Cause ciliary muscle fatigue, produce tension, make the eyes congested, hinder blood circulation, visual fatigue, dry eyes, pain, and even tears, etc., resulting in vision loss of teachers and student staff, affecting physical health, and long-term equipment After use, the surface of the display screen is easy to be stained with dust, which affects observation and reduces the practicability of the existing teaching device
