Multifunctional projection device for Internet of Things education and working mode of multifunctional projection device

Abstract

The invention discloses a multifunctional projection device for Internet of Things education and a working mode of the multifunctional projection device, and relates to the technical field of education equipment. The multifunctional projection device specifically comprises a projector body, a circuit board is arranged in the projector body, an air inlet hole is formed in the bottom of the inner wall of the projector body, heat dissipation structures are arranged on the two sides of the projector body, and the heat dissipation structures are movably clamped on the surface of the circuit board. By arranging the heat dissipation structures, the effect of effectively conducting and rapidly dissipating heat on the circuit board is achieved, by arranging a storage box, a pull wire structure and a rotating plate structure, lifting of the projector body drives the rotating plate structure to close or open the storage box, the projector body is stored through the storage box, and the effects that the projector body is stored and dust entering the projector body is reduced are achieved. A telescopic rod, an adjusting structure A, an adjusting structure B and a rotating structure are arranged, and multi-position automatic adjustment of the height, the levelness, the inclination angle and the projection direction of the projector body is achieved.

Description

technical field [0001] The invention relates to an educational device, in particular to a multi-functional Internet of Things educational projection device and its working method. Background technique [0002] As the name implies, educational equipment is a kind of equipment used for teaching, including computers, sand tables and projection equipment, etc. Among them, projection equipment is a very convenient teaching equipment. Its advantage is that it has a large projection surface. The price advantage, the existing educational projection equipment has the function of the Internet of Things, it is connected to the network itself, no need to use an additional computer for switching, and can be operated by voice, which greatly improves the convenience. [0003] In the prior art, a large amount of heat will come out of the educational projection equipment when it is working. The current method of dissipating this heat is air cooling, which has low efficiency and is difficult ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, a large amount of heat will come out of the educational projection equipment when it is working. The current method of dissipating this heat is air cooling, which has low efficiency and is difficult to use the projection equipment for a long time, and the projection equipment is used for a long time. Using under high temperature will easily cause damage to the equipment, and the existing educational projection equipment is hoisted at the top of the classroom. There are many people in the classroom, which is likely to cause relatively large flying dust. When the educational projection equipment is not in use, it is only turned off. It is still exposed outside, which will cause relatively large dust to enter the interior of the educational projection equipment, which will affect its service life. The most important thing is that the existing educational projection equipment cannot achieve full automatic adjustment. In many cases, people need to manually adjust it. It also increases the inconvenience of educational projection equipment in use
