摘要：
A foam pump for pumping a foamable liquid from a foamable liquid source includes a premix chamber having an interior volume receiving the foamable liquid from the foamable liquid source. The foam pump also include a premix chamber air inlet valve, and a collapsible air chamber surrounds the premix chamber and fluidly communicates with the interior volume of the premix chamber through said premix chamber air inlet valve. The collapsible air chamber has an expanded volume and a compressed volume, and, when the collapsible air chamber is moved from its expanded volume to its compressed volume, air within the collapsible air chamber is forced into the premix chamber through the premix chamber air inlet valve and mixes with the foamable liquid received in the premix chamber. An outlet communicates with the premix chamber and, upon compression of the collapsible air chamber from its expanded volume to its compressed volume, foamable liquid and air are advanced from the premix chamber into the outlet. This foamable liquid and air mixture is homogenized into a foam product by advancement through a mesh screen.一種用於從可發泡的液體源泵抽可發泡的液體的泡沫泵,其包括預混室,該預混室具有接受來自可發泡的液體源的可發泡的液體的內部容積。該泡沫泵還包括預混室空氣進口閥以及可壓縮的空氣室,該可壓縮的空氣室包圍預混室,並且通過該預混室空氣進口閥與預混室的內部容積流體連通。該可壓縮的空氣室具有擴張容積和壓縮容積,並且當可壓縮的空氣室從其擴張容積移動至其壓縮容積時,迫使可壓縮的空氣室內的空氣通過預混室空氣進口閥進入預混室,並與在預混室中接收的可發泡的液體混合。出口與預混室連通,並且在可壓縮的空氣室從其擴張容積壓縮至其壓縮容積時,可發泡的液體和空氣從預混室被推進至出口。通過篩網推進,該可發泡的液體和空氣的混合物被均化成泡沫產品。S...液體10...泡沫泵12...容器14...底座16...預混室圓頂18...扣環20...預混室21...進口通路22...進口閥23...出口24...出口通路26...入口28...分配管尖29...出口閥30...風箱體32...可壓縮的空氣室34...預混室空氣進口閥36...空氣室進口閥40...壟部42...谷部46...篩網48...混合筒50...中空管54...彈簧56...端壁58...肋條60...肋條
