    • Foam dispensers, refill units for foam dispensers, and liquid pumps for use in foam dispensers are disclosed herein. In one embodiment, an inverted foam pump includes a compression chamber having an inlet valve and an outlet valve. The compression chamber is in fluid communication with a flow restrictor, an atomizer, a mixing chamber, a foaming chip and an outlet. The inlet valve, outlet valve, flow restrictor, atomizer, mixing chamber, foaming chip and outlet extend along a common axis. An air inlet is included that extends into the mixing chamber; the air inlet is an opening to atmospheric pressure. During operation, the liquid pump is located below the liquid container and liquid flowing from the compression chamber is accelerated and atomized. The atomized liquid enters the mixing chamber at a velocity sufficient to draw in air from the air inlet to mix with the liquid to form a foam.
    • 本文公开了泡沫分配器,泡沫分配器的补充单元和用于泡沫分配器的液体泵。 在一个实施例中,倒置的泡沫泵包括具有入口阀和出口阀的压缩室。 压缩室与限流器,雾化器,混合室,发泡芯片和出口流体连通。 入口阀,出口阀,限流器,雾化器,混合室,发泡芯片和出口沿公共轴线延伸。 包括延伸到混合室中的空气入口; 进气口为大气压力开口。 在操作期间,液体泵位于液体容器的下方,并且从压缩室流出的液体被加速和雾化。 雾化液体以足以从空气入口吸入空气的速度进入混合室,以与液体混合以形成泡沫。

    • Foam dispensers, refill units for foam dispensers and liquid pumps for use in foam dispensers are disclosed herein. A refill unit for refilling a foam dispenser system is also disclosed herein. The foam dispenser has an air compressor secured thereto and the air compressor is not disposed of with the refill unit. The refill unit includes a liquid pump and a container for holding a foamable liquid that is connected to the liquid pump. The liquid pump includes a pump housing and a mixing chamber having an inlet check valve and an outlet check valve. The mixing chamber has an extended position with a first volume and a contracted position with a second volume. The pump housing includes an aperture therethrough configured to receive air from an air compressor that does not form part of the refill unit. One or more one-way sealing members are located within the pump housing between the aperture and the mixing chamber for preventing liquid from passing through the aperture in the pump housing for receiving air. A foaming element and outlet nozzle are located downstream of the mixing chamber. The refill unit is configured to be received by a foam dispenser having an air compressor located therein and configured to receive pressurized air from the air compressor through the first aperture. In addition, the refill unit may be disposed of without disposing of the air compressor.
    • 本文公开了泡沫分配器,用于泡沫分配器的泡沫分配器的补充单元和液体泵。 本文还公开了用于重新填充泡沫分配器系统的再填充单元。 泡沫分配器具有固定在其上的空气压缩机,并且空气压缩机不与再填充单元一起处理。 再填充单元包括液体泵和用于保持连接到液体泵的可发泡液体的容器。 液体泵包括泵壳体和具有入口止回阀和出口止回阀的混合室。 混合室具有延伸位置,具有第一容积和具有第二容积的收缩位置。 泵壳体包括穿过其构造成从不形成再填充单元的一部分的空气压缩机接收空气的孔。 一个或多个单向密封构件位于泵壳体内的孔和混合室之间,用于防止液体通过泵壳体中的孔以接收空气。 发泡元件和出口喷嘴位于混合室的下游。 再填充单元构造成由具有位于其中的空气压缩机的泡沫分配器容纳,并且构造成通过第一孔从空气压缩机接收加压空气。 此外,可以在不处理空气压缩机的情况下处理替换单元。
