Abstract: The air duct comprises a body and at least an airflow guiding member. The airflow guiding member is detachably configured in a slot outlet of the body. The airflow guiding member comprises a guiding ditch with a receiving section, a regulating section, and a guiding section. An airflow flowing in the body is received by the receiving section into the regulating section and then thrusts out of the body after sequentially compressed by the regulating and guiding sections. An air wall is as such formed above the body to confine the pollutants dispersed in the air.

Abstract: An air curtain-assisted exhaust method and a device thereof are provided. Air curtain generators are disposed on a worktable to enclose an encircled area in the worktable. A receiving hood is disposed above the worktable, wherein the vertical lower part of the outer edge of the receiving hood completely covers the encircled area. Then, the air curtain generators are started to blow out air curtains toward an opening of the receiving hood, and the receiving hood is started to suck an air flow. A shielding space is defined by the air flow sucked by the receiving hood and the air curtains, so that the air curtains may guide a smoke generated inside the shielding space to the receiving hood to be exhausted, thereby achieving the effect of auxiliary exhaust, and may restrict the smoke in the shielding space to prevent the smoke from diffusing laterally.
Abstract: A vehicle lighting device is mounted in a bicycle. The lighting device includes a cantilever, a light-emitting lamp, and a power generating unit. The cantilever is fixed on a frame of the bicycle, so as to support the power generating unit to urge the power generating unit against a wheel of the bicycle constantly. The power generating unit includes an induction coil winding, a magnetic rotor, and a roller. The induction coil winding is wound around a winding axis. A rotating axis of the magnetic rotor is perpendicular to the winding axis. When wheels of the bicycle rotate, the roller and the magnetic rotor are driven to rotate relative to the induction coil winding, such that the induction coil winding generates an inductive electric power, which is supplied to the light-emitting lamp. Thus, a low-cost and labor-saving vehicle lighting device is developed.
