[0001] The utility model relates to the technical field of blinds, and in particular to a ventilation blind capable of preventing electromagnetic interference. Background Art

[0002] With the popularization of modern electronic devices, the problem of electromagnetic interference is becoming increasingly serious. Especially in some places that need to maintain a clean, dust-free, and electromagnetic interference-free environment, such as laboratories and electronic production lines, the impact of electromagnetic interference is more significant. In order to solve this problem, various anti-electromagnetic interference equipment and technologies continue to emerge.

[0003] Among them, ventilation shutters, as a common ventilation equipment, are often affected by electromagnetic interference while maintaining indoor air circulation. Traditional ventilation shutters are generally composed of metal blades. Although they have good conductivity, the electromagnetic shielding effect is not ideal. Therefore, how to improve the anti-electromagnetic interference performance of ventilation shutters has become an urgent problem to be solved. Utility Model Content
