Description

隔膜泡沫泵
本發明屬於泡沫泵(foam pump)的領域,其中能發泡的液體和空氣混合以產生泡沫產品。更具體地,本發明與隔膜泡沫泵有關,其中通過電動馬達驅動元件,隔膜被造成重複地塌陷和膨脹,從而交替地將能發泡的液體和空氣抽入隔膜內的混合室中,並迫使混合物成為泡沫產品出來。
很多年來,從保持再填充單元的分配器殼體分配液體,例如肥皂、消毒劑、清潔劑、殺菌劑等是已知的,該再填充單元容納液體並提供用於分配液體的泵機構。用於這樣的分配器的泵機構一般為在致動器移動時僅分配預定量的液體的液泵。最近,為了效率和節約的目的,以通過將空氣注入液體中而產生的泡沫的形式分配液體變成所希望的。因此,標準液泵讓位於產生泡沫的泵,其必定需要用於以產生期望的泡沫的方式合併空氣和液體的裝置。
一般,泡沫分配器通過將能發泡的液體流和空氣流泵送到混合區域並迫使混合物通過篩子來產生泡沫,以更好地將空氣成為氣泡分散在能發泡的液體內,並產生更均勻的泡沫產品。氣泡越小和越多,泡沫就越厚和越軟,雖然太多或太少的空氣可能使泡沫有不良的品質。形成期望的泡沫產品的關鍵是强烈混合能發泡的液體和空氣,以將氣 泡分散在液體內。很多現有的泡沫泵設計使用活塞型機構,其導致泡沫泵的每次致動產生的固定量的泡沫,而沒有任何調節能力。因此,存在對一種泡沫泵的需要,該泡沫泵提供能力來調節泡沫泵的每次致動所提供的泡沫的量。
一種隔膜泡沫泵包括隔膜,隔膜由撓性材料製成,界定混合室,並具有入口開口和出口開口。入口通道與包含能發泡的液體的貯器和入口開口流體相通,且入口通道在其內具有單向閥。泵還包括與出口開口流體相通並在其內具有單向閥的出口通道,且入口通道中的空氣入口具有單向閥。隔膜泡沫泵進一步包括電動馬達和與該電動馬達連接的電動馬達驅動的元件。致動該電動馬達驅動該電動馬達驅動的元件以使隔膜重複地塌陷和膨脹,且其中隔膜的膨脹產生真空,使能發泡的液體和空氣流入混合室中,而隔膜的塌陷使液體和空氣混合物被迫通過出口通道成為泡沫出來。
根據本發明的概念的分配器在圖1中示出並通常由數字10表示。分配器10包括具有隔膜12的泡沫泵11,隔膜12通常是圓頂形狀的。隔膜12由撓性和彈性材料製成,隔膜12在引入外力時塌陷,接著,當力被除去時, 返回到其原始形狀。適當的材料包括例如矽樹脂、熱塑性彈性體等。隔膜12界定其內的內部混合室14,這將在下面更詳細討論。隔膜12可安裝在提供安裝機構以及用於固定分配器10的其它部件的分配器殼體(未示出)中。
分配器10也包括具有旋轉電動馬達軸18的電動馬達16。電動馬達16可為具有旋轉軸的任何已知的電動馬達,包括例如設置有電池電源19的DC電動馬達。電動馬達16可包括電動馬達驅動電路17以控制對其的致動(例如持續時間、速度等)。電動馬達16的驅動電路17可由免持致動傳感器激勵,如在本領域中已知的。凸輪20固定到旋轉軸18,使得旋轉軸18使凸輪20旋轉。在圖1和2中,示出凸輪20偏心地安裝在軸18上,以便軸18的旋轉能夠產生作用在隔膜12上的線性力,隔膜12因而像凸輪從動件一樣起作用。然而,如在圖3中看到的,凸輪也可為具有適當的突出部分的簡單的中央安裝的輪,如在凸輪20’所示的。
如在圖1中看到的,電動馬達16定位成使得軸18相鄰於隔膜12延伸,軸18與隔膜12分開一段選定的距離,以便在軸18(且如此凸輪20)的全程旋轉期間的至少一個點處,隔膜12可呈現其完全膨脹的形狀。當電動馬達16的軸18旋轉時,凸輪20重複地將力施加在隔膜12上,從而使隔膜12在凸輪20旋轉到隔膜12中時塌陷,且當凸輪20繼續其旋轉時,隔膜20接著膨脹回其原始位置。
隔膜12包括在其基部23上的入口開口22,入口開口與入口通道24流體相通,入口通道24與容納能發泡的液體S的容器26流體相通。如所示,入口通道24是在一端浸沒在能發泡的液體S中的管。單向閥28設置在入口通道24中,以允許流體流入混合室14中,同時阻止流體在相反的方向上朝著貯器26流動。單向閥28可為本領域中已知的任何這樣的閥,並可包括例如球閥、鴨嘴閥、擋板閥等。入口通道24也在其中包括空氣入口30,其允許空氣被抽到入口通道24中並在入口通道24中與能發泡的液體S混合,如將在下面從進一步的公開中認識到的。空氣入口30包括類似於閥28的單向閥32,以阻止空氣或液體從入口通道24漏出。
雖然被示意性地示出以粗略地公開本發明的概念,應認識到,隔膜12是習知的泵結構,且如已知的,可固定到容器,以提供通常被稱為分配器殼體的再填充單元的東西。特別在肥皂和消毒劑分配領域中,通常提供適合於接納再填充單元的分配器殼體,該再填充單元主要由肥皂或消毒劑容器組成,而隔膜泵固定到該容器。可使用這樣的再填充單元,並以這裏公開的方式對隔膜起作用以分配產品。
出口通道36與基部23中的出口開口38流體相通。出口通道36為管的形式,並在開口40終止。單向閥42設置在出口通道36中,以允許流體從隔膜12流出,但阻止流體在相反的方向上流動。與單向閥28一樣,閥42可 為本領域中已知的任何這樣的閥,並可包括例如球閥、鴨嘴閥、擋板閥等。
當致動電動馬達16時,軸18和凸輪20在固定的一段時間內旋轉,這由控制電路所控制。當凸輪20旋轉到隔膜12中並從隔膜12旋轉出時,凸輪20的旋轉引起隔膜12的重複和快速的塌陷和膨脹。每當隔膜12塌陷時,混合室14的減少的內部容積產生高壓,該高壓迫使混合室14的容納物通過單向閥42出來,並進入出口通道36中。當隔膜12膨脹回到其原始位置時,混合室14的內部容積增加,產生真空。真空沿著入口通道24抽空氣和能發泡的液體,並通過單向閥28將它們抽入混合室14中。空氣在開口30處通過單向閥32被抽入入口通道24中。在一個實施方式中,空氣僅由於液體通過開口30的運動,即,依靠文托利效應(Venturi effect)而被抽入通道24中。如本領域中具有通常知識者已知的,通過將通道24內的流量限制器(flow restrictor)在與空氣入口30相鄰處,以增加流動的速度,從而降低在被限制流處的壓力,可增强文托利效應。可選地,空氣泵34可用於在空氣入口30處提供加壓的空氣。空氣泵34可由電動馬達16的控制電路17控制,以便電動馬達16的啟動同時引起空氣泵34的致動。
被抽入入口通道24的空氣與能發泡的液體S粗略地混合。由於凸輪20的高速旋轉,因而由於隔膜12膨脹和塌陷的快速頻率,空氣和能發泡的液體在它們通過混合室 14循環時被强烈地攪動和更徹底地混合。該混合物前進到開口40並成為泡沫被分配。電動馬達致動的時間段可通過改變控制電路17來調節,以控制在泡沫泵10的每次致動時分配的泡沫的量。旋轉速率也可對給定的液體/空氣混合物改變,因為可能發現不同的混合物在較小或較大的攪動下變成泡沫。
出口通道36可以可選地包括與開口40相鄰的至少一個網篩44,用於在分配之前擠出空氣和能發泡的液體混合物。然而應理解,在一些實施方式中並對於一些液體和空氣混合物,由於液體和空氣在混合室14中的徹底混合和攪動,將不需要網篩。可以按混合匣46的形式設置所述的至少一個網篩44,混合匣46由在兩端以網篩44為界的中空管48組成。如果設置了混合匣46,則可進一步均質化所形成的混合物,以提高在開口40處被分配的泡沫產品的品質。
在圖14中示出用於使隔膜12快速膨脹和塌陷的可選實施方式,其中電動馬達16驅動往復式活塞50,以壓在隔膜12上並允許其返回到其膨脹狀態,非常像凸輪20的旋轉。這種往復運動在圖4中由雙向箭頭表示。因此,概括地,電動馬達16驅動由電動馬達驅動的元件來使隔膜12快速塌陷和膨脹,以將空氣和液體抽入混合室中,在混合室內强烈地混合它們,並使它們成為泡沫排出到出口。
根據前述內容,應清楚,本發明提供了泡沫泵領域中的改進。雖然為了教導發明性概念的目的在這裏公開了特 定的實施方式,但應認識到,本發明不限於所示和所述的任何特定的結構或被該結構限制。更確切地,申請專利範圍應當用於限定本發明。
