Problems solved by technology

[0003] At present, with the development of the times, people's living standards are constantly improving, and people's requirements for the teaching environment are getting higher and higher. Projectors are also widely used in education and teaching, and during the use of projectors, due to internal and external The temperature difference causes a layer of fog on the inner mirror of the projector lens. Because the fog is attached to the inner mirror, it affects the clarity of the projector when projecting, interferes with it, and is not convenient for people to watch, thus affecting people's viewing experience At the same time, the effect of teaching is reduced, and because there are many uncontrollable factors in the outside world, when external objects collide with it, the traditional device lacks protective devices to effectively protect it, resulting in damage to the device , which in turn affects people's teaching effect, so it cannot meet the needs of users. Therefore, it is necessary to further improve

Abstract

The invention provides a projector lens anti-interference device for teaching. The device comprises a shell, a supporting base assembly is fixedly installed at the bottom of the shell, a driving power supply assembly is installed in the shell, a projection assembly is installed on the right side of the shell, a mist cleaning assembly is installed on the inner wall of the projection assembly, a linkage induction assembly and a driving assembly are installed in the mist cleaning assembly, and the linkage induction assembly comprises a fixed base. According to the projector lens anti-interference device for teaching, kinetic energy is generated through a driving mechanism, and a cleaning air bag is extruded by driving a telescopic rod, so that airflow in the cleaning air bag is transmitted to a cleaning head, and then the airflow is sprayed out at a high speed through the cleaning head, so that the airflow can automatically blow water mist on a projection lens, water mist on the projection lens can be blown and wiped clean, pictures projected by a projection mechanism are clear, and the teaching effect on people is further improved.

Description

technical field [0001] The invention belongs to the technical field of projectors, in particular to an anti-interference device for teaching projector lenses. Background technique [0002] Education is one of the most important issues that people are most concerned about. The quality of education is crucial to China's modernization drive, and also plays a key factor in the future development of individuals. Therefore, parents pay special attention to the quality of their children's education. [0003] At present, with the development of the times, people's living standards are constantly improving, and people's requirements for the teaching environment are getting higher and higher. Projectors are also widely used in education and teaching, and during the use of projectors, due to internal and external The temperature difference causes a layer of fog on the inner mirror of the projector lens. Because the fog is attached to the inner mirror, it affects the clarity of the proj...
