摘要： A smokeless ashtray system includes a vacuum manifold connecting a plurality of ashtrays to a charcoal filter and a vacuum blower/motor assembly. The vacuum manifold includes spiral wound metal flexible metal tubing segments secured to connectors by heat shrink tubing. L connectors connect end most ashtray locations to the manifold, T connectors connect intermediate ashtray locations, and a four-way connector connects a central ashtray location to the manifold and to the charcoal filter and blower/motor assembly. Each ashtray location includes a flue member having a first end threaded into the associated connector and a second end inserted within a recess formed centrally in a bottom surface of a cup-shaped ashtray. A connector mounting bracket includes locating apertures engaging alignment pins extending from a flat upper surface of the connector, and a flange on the flue member clamps the bracket to the connector. Screws secure mounting flanges of the bracket to the underside of a table or other mounting surface. A central chimney in the ashtray includes a shield dome covering an open top end to prevent ashes and other debris from entering the air flow path. A replaceable disposable coalescing filter element in the flue member filters smoke prior to passage into the manifold, thus substantially reducing tar fouling of the system. A control box includes an on/off switch, a power on LED, and a service needed LED activated by monitoring load on the motor to indicate filter clogging.

摘要翻译： 无烟烟灰缸系统包括将多个烟灰缸连接到炭过滤器和真空鼓风机/电动机组件的真空歧管。 真空歧管包括通过热缩管固定到连接器的螺旋缠绕金属柔性金属管段。 L连接器将大多数烟灰缸位置连接到歧管，T连接器连接中间烟灰缸位置，四通连接器将中央烟灰缸位置连接到歧管以及炭过滤器和鼓风机/电机组件。 每个烟灰缸位置包括烟道构件，其具有螺纹连接到相关联的连接器中的第一端和插入在杯形烟灰缸的底部表面中央形成的凹部内的第二端。 连接器安装支架包括定位孔，其接合从连接器的平坦上表面延伸的对准销，并且烟道部件上的凸缘将支架夹持到连接器。 将支架的安装法兰固定到工作台或其他安装表面的下侧。 烟灰缸中的中央烟囱包括覆盖开放顶端的防护罩，以防止灰烬和其他碎屑进入空气流动路径。 烟道构件中的可更换的一次性聚结过滤元件在通入歧管之前对烟雾进行过滤，从而大大减少系统的焦油结垢。 一个控制箱包括一个开/关开关，一个通电指示灯和一个服务需要的LED通过监视电机上的负载来激活以指示过滤器堵塞。
