Problems solved by technology

[0002] Multimedia teaching means that in the teaching process, according to the teaching objectives and the characteristics of the teaching objects, through teaching design, rationally select and use modern teaching media, and organically combine with traditional teaching methods, participate in the whole teaching process together, use various media information For students, form a reasonable teaching process structure to achieve the optimal teaching effect; multimedia English teaching is the concept of education based on the combination of computers, projectors, audio and other equipment with modern educational technology; when teachers conduct multimedia English teaching, they generally use The multimedia equipment and the blackboard are used for teaching at the same time. When using the blackboard, chalk dust will be generated. After long-term use, the projection cloth of the projector will be stained with chalk dust, which will affect the projection effect of the projector, so that the students can not see the projection screen clearly, and then It affects the teaching effect; in the prior art, the dust on the curtain cannot be collected after brushing off the dust, so that the dust floats in the air, which will affect the health of the human body after inhalation

[0003] For example, a Chinese patent with the application number CN202021297744.1 discloses a projection screen that can realize speed-adjustable rewinding of the curtain, including a rewinding and dust removal device, a wall plate, a hook and a base plate; the wall plate is arranged on the base plate; The hook is set at the lower end of the side of the wall plate, and the winding and dust removal device is set at the upper end of the side of the wall plate and above the hook; in this technical solution, the dust on the projection screen is removed by the dust removal component, and the projection screen is lightly and gently moved by the roll-up component. When the projection screen is rolled up, the uncleaned side of the projection screen and the cleaned one Side contact, so that the side of the projection screen after cleaning is stained with dust, which cannot achieve the effect of cleaning the dust on the screen, which in turn causes the limitations of this solution
