Description

Technical Field

[0001] The present invention relates to the technical field of e-commerce teaching, and in particular to an Internet e-commerce learning device based on an artificial intelligence large model.

[0002] Artificial intelligence big model fusion: The device applies artificial intelligence big model technology to the field of e-commerce teaching. Through deep learning and big data analysis, it provides learners with personalized learning content and suggestions to improve learning efficiency.

[0003] Projection device cleaning system: The equipment has a uniquely designed projection device cleaning system. Through the cooperation of the plug barrel, plug head, air bag and other components, it realizes automatic cleaning of the projection device lens, ensures the clarity of the projection image, and thus improves students' learning experience and teaching effects. Background Art

[0004] The emergence and development of e-commerce cannot be separated from the support of computer and network technology, and is also driven by the changes in social economy and business models. E-commerce has had a profound impact on traditional business models by reducing transaction costs and improving transaction efficiency.

[0005] With the rapid development of the e-commerce industry, new technologies, cases and strategies are constantly emerging. Projectors can easily connect to the Internet and update teaching content in real time. Projectors can display a large amount of information at one time, avoiding the situation in which teachers need to constantly write and explain in traditional teaching, saving class time. At the same time, students can browse and understand information more quickly, improving classroom efficiency.

[0006] By integrating artificial intelligence big models, e-commerce platforms can provide smarter and more personalized services to meet the diverse needs of consumers, and then project consumers' consumption needs and consumption habits through projection equipment, thereby promoting the skill level of practitioners in this field and the development of e-commerce. Since existing projectors are directly placed on the support table, when the support table or the projector is disturbed by external forces, the projector will slide on the support table and slide off the support table, causing the projector to fall to the bottom, causing damage to the projector shell, internal components and lens, resulting in the projector being unable to be used normally, affecting the teaching effect and reducing the students' learning efficiency;

[0007] In addition, when the projector is not in use, the lens of the projector is exposed to the external environment for a long time, causing dust or dirt in the air to adhere to the lens surface. The dirt will corrode the lens and affect the glossiness of the lens surface. At the same time, the Internet e-commerce learning content based on the artificial intelligence large model projected by the projector during use is blurred and has low cleanliness, affecting students' learning viewing experience and learning efficiency.
