    • 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.
    • 提供了一种空气幕辅助排气方法及其装置。 气帘发生器被放置在工作台上以将包围的区域包围在工作台中。 接收罩设置在工作台的上方,其中接收罩的外缘的垂直下部部分完全覆盖环绕的区域。 然后,启动气帘发生器朝向接收罩的开口吹出气帘,开始接收罩吸入空气流。 屏蔽空间由接收罩和气帘吸引的气流限定,使得空气幕可以将屏蔽空间内产生的烟引导到待排气的接收罩,从而达到辅助排气的效果, 可能限制屏蔽空间中的烟雾,以防止烟横向扩散。
