A fan device with air guide function, which contains at least a fan device and is characterized by comprising an air guide frame, wherein the said air guide frame is composed of at least two layers inclined guide which are configured as a symmetrical geometrical shape or at least two layers of arc-overlapped inclined guide which forms a arc-overlapped air guide frame, and are both connected by the securing elements. By the combination of the fan device and both embodiments of the air frame guide, the present invention is applicable to guide the air flow propelled from the fan with a prolonged air path in the space and provides higher air molecule freedom by the effect of more frequent collision which results each loose air molecule has larger surface area existing and moving in the air flow, enables a better indoor air circulation and forms comfortable and nature breeze.
