    • A hand-actuated multiple-container trigger sprayer includes a sprayer head assembly removably connected to a plurality of fluid containers. The sprayer head assembly has an outer housing, a nozzle attached to the housing, pump mechanism enclosed within the housing, and tubing fluidly connecting each of the plurality of fluid containers with the pump mechanism in the housing. A trigger or lever actuates the pump mechanism to draw fluid through the tubing from each of the plurality of fluid containers and to discharge the fluid through the nozzle. A metering device is located between the fluid containers and the pump mechanism and is accessible externally from the housing to selectively control the amount of fluid drawn from the containers. The metering device includes flow paths to the pump mechanism for each of the fluid containers. The diameter and length of at least one of the flow paths can be controlled to selectively control the amount of fluid drawn from the fluid containers.
    • 手动多容器触发式喷雾器包括可移除地连接到多个流体容器的喷雾头组件。 喷雾器头组件具有外壳,连接到壳体的喷嘴,封闭在壳体内的泵机构,以及将多个流体容器中的每一个与壳体中的泵机构流体连接的管道。 触发器或杠杆致动泵机构以从多个流体容器中的每个流体通过管道抽取流体并且通过喷嘴排出流体。 计量装置位于流体容器和泵机构之间,并且可从壳体外部进入,以选择性地控制从容器抽取的流体的量。 计量装置包括到每个流体容器的泵机构的流动路径。 可以控制至少一个流动路径的直径和长度以选择性地控制从流体容器抽取的流体的量。
