    • An ashtray has a base with a lid hinged thereto. A filter is in the lid in order to accommodate an easy filter replacement. An air duct in the lid enables a fan in the base to draw smoke through the filter and out the base. The fan is operated in response to raising the lid to an upright position. The intake to the air duct is far enough from debris in the ashtray to preclude drawing the debris into the air duct. The lid tends to seal in odors when it is closed. An area in the base may also receive a filter in order to provide a compatibility with preexisting filters.
    • 烟灰缸具有与其铰接的盖的基部。 过滤器在盖子中,以适应容易的过滤器更换。 盖子中的风道使得底座中的风扇能够通过过滤器抽出烟雾并从底部吸出烟雾。 响应于将盖抬高到直立位置,风扇被操作。 进入风道的进气距离烟灰缸中的碎片足够远,以排除将碎屑吸入风道。 当盖子闭合时,盖子将密封在气味中。 基座中的区域也可以接收过滤器以提供与预先存在的过滤器的兼容性。
