下，可朝泵的某一方向彈性壓縮。且，該泵室透過一排出 . 閥直接或間接與一排出件相連接，以排出一定量的介質； 又，該泵室透過一流入閥直接或間接與該儲藏容器相連 接。 又，本發明係有關於一種配給器單元，該配給器單元 用來排放液態狀，粘稠狀或泡沫狀介質，其中，該介質以 參 液態狀或粘稠狀放置於儲藏容器内。該配給器單元具有一 配給器殼體，該配給器殼體内可設置一填充頭，該填充頭 最好由一儲藏容器以及位於該儲藏容器上之吸泵組成，且 該儲藏容器係藉由吹塑成型方法製成。在掀開殼蓋之後， 將填充頭置入配給器殼體内，從而在整個安裝過程中，透 過一插入裝置夾住吸泵頭部，並最終將其與一操作裝置相 連接。其中，該插入裝置由一所謂的「捕捉夾」構成，而 該操作裝置可為一機械壓鍵，如「推鍵」，其透過一杠桿 3 201008541 與該插入裝置相連接。或者，亦可設置一非接觸性操作裝 置，此時，使用者藉由觸動一感測器來驅動一電動驅動 器，從而操作吸泵。 【先前技術】 EP 1 711 094係揭示了一種該類型之配給器單元，此 外，上述吸泵一般被稱為為波紋管泵，其具有一泵室，該 泵室具有一橡膠壁，通常藉由手工擠壓壓縮該橡膠壁，並 擠出泵室内的介質。該種波紋管泵具有製作簡單，生產成 本低的優點。 然，傳統波紋管泵亦具有以下之缺陷：用手很容易實 現的擠壓運動，用機械結構較難實現，為了防止排出口側 移，只能透過附加導件，故波紋管泵並非完全適用於排出 裝置内。又，波紋管泵在用於精確配給一定量的介質時也 有問題，因為，為了避免損壞彈性壁，通常情況下，泵室 並不能被徹底壓緊，故，排出體積與彈性壁之變形狀況有 關。 波紋管泵之另一缺陷在於：在連接配給器單元的過程 中，不容易安裝填充頭（由儲藏容器和與之相連的吸泵構 成）。若將填充頭推入打開的配給器殼體内，則插入裝置 擠壓泵之功能部件，以透過一「捕捉夾」連接操作裝置或 驅動器與泵構件。在安裝填充頭的過程中，即使安裝過程 201008541 沒有認真實施，也必須保證泵與操作裝置或驅動器之間的 ： 機械連接，否則配給器之功能則無法實施。 ' 在運用波紋管泵時，由於泵下部部件的壁具有彈性， 故「捕捉夾」的夾持位置可能會有變化，尤其是當泵橫向 擺放時，透過操作配給器雖然可以壓縮彈性壁，但該介質 . 將以垂直於預定的方向輸出供應至配給器殼體内。又，「捕 捉夾」也可能只是部分夾住泵底部。上述兩種情況顯然都 ® 會導致配給器失去其功效。 【發明内容】 本發明之主要目的在於提供一種具有彈性壁之吸泵以 及一配給器單元，該吸泵結構簡單，生產成本低，且可盡 可能無缺陷地用於一排出裝置内，尤指一配給器單元内； 又，本發明之配給器單元，可供帶有彈性泵室之吸泵盡可 φ 能無缺陷地安裝進去。 為達到本發明之吸泵之目的，其係設置數個導件，在 壓縮泵體過程中，該導件可阻止泵體之彈性壁產生垂直於 果方向的偏移。 為達到本發明之配給器之目的，該配給器殼體係設有 一插入裝置，以使與操作裝置共同作用的吸泵頭在推入過 程中，透過將填充頭推向最終位置，而被一插入裝置自動 夾住，又，藉由導件可避免彈性泵室彎曲。 5 201008541 透過本發明之吸泵，可將習知之活塞泵之優點與波紋 管泵相聯繫。透過導件可將壓縮運動限制在泵運動之優先 方向上，習知之配給器之優先方向為垂直方向。同時，將 儲藏容器與吸泵向下，掛到配給器殼體内，且，儘管泵壁 具有彈性，但導件依然可以避免橫向上之偏移。泵體只在 垂直方向上被壓縮，從而，將插入裝置安裝到吸泵頭的過 程中，即使在摩擦力作用下，吸泵頭也不會產生橫向偏移。 吸泵尤其簡單之構造為：泵室由一彈性壁，一頭部以 及一底部所構成。底部位於倒立設置的填充頭上部並設有 一流入閥，該流入閥在拉伸泵室時，可將介質由儲藏容器 吸入泵室内，並在壓縮泵室時鎖閉。該頭部設有一排出 閥，其在壓縮泵室時配給介質，並在拉伸泵室時關閉。尤 其，也可在頭部，或者也可是底部，設置其他功能件，以 將介質泡沫化，或避免配給完成之後仍有介質滴下。 在本發明之吸泵之一較佳實施例中，導件至少要作用 於吸泵頭部，且吸泵底部相對於配給器殼體固定。又，透 過導件，可確保吸泵頭部，相對於吸泵之固定底部，在泵 優先方向上運動。 透過安裝導件，且導件只在一個方向上施加導向力， 可確保配給器之功能。在上述之配給器單元中，透過導件 可以避免安裝填充頭時所引起的偏移現象，從而，導向裝 置只是提供一與安裝運動反作用之支架。故，在將填充頭 201008541 從前向殼體後壁安裝過程中，導件必須避免波紋管栗頭部 朝"又體後壁運仃。為了提高功能安全性，最好在整個運行 過程中，都對果頭部進行引導。應在整個移動路徑和垂直 於泵優先方向來對泵頭部進行引導。 吸果之頭部可具有一外凸邊緣，其在安裝進配給器殼 =的過程中’可被-插人裝置，尤指「捕捉夾」夾住。該 Φ ’緣可為触，透過該邊緣，可避免插人裝置損壞彈性 壁。按照壁之不同構造，泉之頭部可為盤狀，或者，亦可 -有盤狀部’其可透過—間隔塊，與泵頭部和彈性壁之 交界部分相連接。 導件既可為内導件，也可為外導件。若導件為外導件， ^吸U果體’且栗室設於㈣上。最簡單的方法 是：本體由底部形成，導件以導桿之形式，通過在頭部設 置的箱眼，從底部開始朝頭部方向延伸，從而實現導向功 能。 、此外’導件也可以由泵體壁形成，其可象手風琴一樣， 伸縮才干的形式擠到一起。又，頭部亦可具有一活塞式外 之邊緣’該邊緣在柱狀果體内，被引向果優先方向，同 、’頭部之另一部分，即頭部背離栗室之活塞式部分，連 =以作裝置上’且該部分在頭部所有位置從該圓柱區域 〜可為排出管，且，該排出管在其底部設有侧邊 犬出的盤狀邊緣’插人裝置設置在該邊緣上。 7 201008541 或者，頭部亦可具有一由底部方向向上突出之柱狀壁 部，該壁部與一盤狀部連接，該盤狀部又與泵室之彈性壁 相連接。又，頭部之柱狀壁朝向泵體或者底部。 為了確保吸泵在輸送過程中的安全性，該實施例之吸 泵底部可移動到輸送位置，此時，柱狀環體之高度至少相 當於泵室之高度，從而使底部可以被推至環體之上邊緣， 並最終將整個泵室置於該圓柱狀環體内。 或者，具有輸送安全裝置之吸泵也可具有一鐘狀底 部，其向頭部方向延伸，且，泵室之彈性壁連接于底部之 鐘狀部下部。為了形成一輸送安全裝置，泵室壁之彈性部 分與頭部一起向内翻轉，以使頭部與底部相互靠近，並使 泵失去功效。 在安裝過程中，插入輔助裝置亦可以不僅夾住頭部之 一邊緣，使其與操作裝置相連接，而且還可以在裝入過程 中，使輸送安全裝置失去功效，並在第一次推入過程中， 使頭部運行很長一段路程，從而使泵室之彈性壁部又向外 翻轉。 該發明之結構之優點在於：其係透過流入閥和排出閥 之推桿形成導件。流入閥與排出閥分別設置一推桿，該推 桿具有閥部件，如密封膜片。推桿長於閥部件部分，並在 超出部分設有一導部，該導部受導件引導，且，按照推桿 是流入閥之推桿，還是排出閥之推桿，導件可分別位於泵 201008541 體，泵頭部或底部。又導向裝置之相應部分最好設有箱 眼，導部位於箱眼内，且可沿泵優先方向移動。 泵發明之另一較佳實施例中，流入閥與排出閥可共同 設有一推桿，該推桿最好為穿過泵室之中心推桿，且，開 關部件在其中一個閥門之側面與該推桿固定連接，在另一 . 閩門之侧面可移動式支承於推桿上。例如，開關部件可在 排出閥側面與推桿固定連接，而在流入閥之側面，可移動 ® 式的設置在推桿上，從而使流入閥與排出閥可以單獨的在 壓力作用下動作。在壓縮波紋閥門時，推桿可以伸入儲藏 容器内，亦可伸入吸泵和儲藏容器之中間區域。 上述之實施例，可透過下列方式製成：流入閥之開關 部件可具有一管狀部分，其用於縱向導向推桿。透過設置 限位元，可限制開關部件在推桿之二方向上的相對移動， 同時，可以確定波紋泵之整個壓縮運動，從而避免彈性壁 材料藉由過分變形而損壞。又該結構中，最好藉由一個或 兩個閥門之閥座，即透過流入閥或排出閥之閥座，來支承 該推桿。或者，推桿也可以在泵的優先方向上，活動支承 於泵室内或泵室外而形成一（附加）導向裝置。 排出閥在所有實施例中都可設一推桿，該推桿在背離 泵室之方向上延伸，並在底部具有一盤狀區域，透過該盤 狀區域，可將推桿與配給器之操作裝置相連接。當然，也 不一定非要設置一盤狀區域，推桿亦可以透過其他機械式 9 201008541 的裝置與配給器之操作裝置相連接。 本發明之操作裝置與之前發明中所述之操作裝置同， 其可為任何形式的閥門操作裝置，尤其可以為一機械壓鍵 或一電動驅動器，該電動驅動器透過一感測器觸發。排出 閥之從泵室伸出之推桿，背離泵室延伸，並，最好為空心 柱狀，從而透過該推桿將介質送到出口，在此，推桿形成 介質輸出通道。為了防止多餘介質滴出，不管該輸出通道 由推桿形成，還是為一獨立通道，都可以在輸出通道内另 外設置一密封件或閥門件，在此可考慮設置一密封膜片。 本發明之配給器單元包括一殼體，填充頭可置於殼體 内。如前所述，該填充頭由儲藏容器和其内設置之吸泵構 成。吸泵為波紋管泵，並具有一頭部，該頭部可朝向底部 之方向移動，以傳送操作力，該操作力或者透過一電動驅 動器，或者透過一推鍵形成。同時，吸泵亦具有導件，以 確保頭部向泵優先方向移動。通常情況下，填充頭與吸泵 向下放於殼體内，從而使泵優先方向為向下之垂直方向， 最終使排出介質直接由排出方向滴向使用者手上。 該配給器單元最好具有一插入裝置，其可由一「捕捉 夾」形成，該捕捉夾為一具有圓形或弧形角之u字形夾， 在將填充頭置入配給器單元内時，捕捉夾從後面夾住吸泵 活動部分之邊緣，尤指夾住頭部指邊緣。而插入裝置又與 殼體機械功能性連接，借此，可透過操作裝置之運動，帶 201008541 動與插入裝置相連接之吸泵邊緣的運動。從而，壓縮泵室 並將介質藉由泵優先方向，排出泵室。 若吸泵具有上述之輸送安全裝置，則配給器單元亦可 另外設置一插入輔助裝置，其與另外一插入件一起作用於 吸泵之活動部分。該另設之插入輔助裝置可作用於第一段 .路程，使泵室之彈性壁向外翻轉，以使輸送安全裝置失 效，在裝入過程中，外設之插入件沿著另一插入輔助裝置 ® 之導向面滑動，並使頭部移動到使用位置。 或者，外設之插入輔助裝置也可串接在第一插入輔助 裝置上，該第一裝置「捕捉夾」，且該捕捉夾具有向泵優 先方向彎曲之弧形角。 又，該吸泵可具有一漏滴保護，其位於泵室後面並可 由一密封膜片構成，例如該密封膜片可象心臟瓣膜一樣， 藉由數個，如三個瓣膜構成，且瓣膜在靜止狀態時，相互 翁 合併成一封閉回路；而在排出介質壓力作用下，在排出方 向上相互分開。又，瓣膜又透過邊緣與排出通道壁連接， 其中該邊緣與其他瓣膜隔離，且，瓣膜在靜止狀態時，與 其相應邊緣疊合。 · 當介質穿過密封件時，該折疊式瓣膜朝壁方向打開， 以使介質穿過。當壓力減小時，瓣膜在彈性回復力作用 下，重新關閉。藉由與流動方向相反之運動，介質重新被 吸回排出通道，從而避免多餘介質滴落。 201008541 當然’也可以採用其他方法來形成—漏滴保護或類似 之功能，如排出通道内之吸管式回流震置，或闕門，或闕 片’該類裝置在封閉方向上藉由彈簧作用，並透過菜麼予 以開啟。 【實施方式】 如第1圖所示’本發明之配給器單元具有一配給器殼

Description of the Invention: [Technical Field of the Invention] The present invention relates to a suction pump, and more particularly to a bellows pump of a dispenser unit, wherein the dispenser unit is for discharging a viscous, foamy shape and Liquid medium such as liquid soap, skin lotion or other liquid skin cleansers or skin care products. The suction pump has a fixing member and a pump chamber, and the fixing member seals and fixes the suction pump to the 储藏 storage container containing the liquid medium, the pump chamber has an elastic wall, and the pump chamber is pumping Under the action, it can be elastically compressed in one direction of the pump. Moreover, the pump chamber is directly or indirectly connected to a discharge member through a discharge valve to discharge a certain amount of medium; and the pump chamber is directly or indirectly connected to the storage container through an inflow valve. Further, the present invention relates to a dispenser unit for discharging a liquid, viscous or foamy medium in which the medium is placed in a liquid or viscous state in a storage container. The dispenser unit has a dispenser housing, and a filler head is disposed in the dispenser housing. The filler head preferably comprises a storage container and a suction pump located on the storage container, and the storage container is Made by blow molding. After the cover is opened, the filling head is placed in the dispenser housing so that the suction pump head is clamped through an insertion device and finally connected to an operating device throughout the installation. The insertion device is constituted by a so-called "capture clip", and the operation device can be a mechanical press key, such as a "push button", which is connected to the insertion device via a lever 3 201008541. Alternatively, a non-contact operating device may be provided, in which case the user operates the suction pump by actuating a sensor to drive an electric drive. [Prior Art] EP 1 711 094 discloses a dispenser unit of this type. Further, the suction pump is generally referred to as a bellows pump having a pump chamber having a rubber wall, usually by The rubber wall is compressed by hand and extruded into the medium in the pump chamber. This type of bellows pump has the advantages of simple manufacture and low production cost. However, the conventional bellows pump also has the following drawbacks: the squeeze movement which is easily realized by hand is difficult to realize with a mechanical structure, and the bellows pump is not fully applicable in order to prevent the discharge port from moving laterally only by the additional guide member. In the discharge device. Moreover, the bellows pump is also problematic when used for accurately dispensing a certain amount of medium, because in order to avoid damage to the elastic wall, the pump chamber cannot be completely pressed under normal circumstances, so the discharge volume is related to the deformation state of the elastic wall. . Another disadvantage of the bellows pump is that it is not easy to install the filling head (consisting of the storage container and the suction pump connected thereto) during the connection of the dispenser unit. If the filling head is pushed into the open dispenser housing, the insertion device squeezes the pump's functional components to connect the operating device or the actuator to the pump member through a "catch clamp". During the installation of the filling head, even if the installation process 201008541 is not implemented carefully, the mechanical connection between the pump and the operating device or the drive must be ensured, otherwise the function of the dispenser cannot be implemented. ' When using the bellows pump, the clamping position of the "capture clip" may change due to the elasticity of the wall of the lower part of the pump, especially when the pump is placed laterally, although the elastic adapter can be compressed by operating the dispenser, However, the medium will be supplied to the dispenser housing in a direction perpendicular to the predetermined direction. Also, the "catch catch" may only partially pinch the bottom of the pump. Obviously both of these conditions will cause the dispenser to lose its effectiveness. SUMMARY OF THE INVENTION The main object of the present invention is to provide a suction pump with an elastic wall and a dispenser unit, which has a simple structure, low production cost, and can be used as far as possible without defects in a discharge device, especially In the dispenser unit, the dispenser unit of the present invention can be installed in a suction pump with an elastic pump chamber so that it can be installed without defects. For the purpose of the suction pump of the present invention, a plurality of guide members are provided which prevent the elastic wall of the pump body from being displaced perpendicular to the direction of the fruit during compression of the pump body. For the purpose of the dispenser of the present invention, the dispenser housing is provided with an insertion device such that the suction pump head cooperating with the operating device is inserted during the pushing process by pushing the filling head to the final position. The device is automatically clamped and, in turn, the flexible pump chamber is prevented from bending by the guide. 5 201008541 The advantages of conventional piston pumps can be linked to bellows pumps by the suction pump of the present invention. The guide movement restricts the compression movement to the preferential direction of the pump movement. The preferred direction of the conventional dispenser is the vertical direction. At the same time, the storage container and the suction pump are lowered downward into the dispenser housing, and although the pump wall is elastic, the guide can avoid lateral displacement. The pump body is only compressed in the vertical direction, so that the insertion device is installed in the suction pump head, and the suction pump head does not have a lateral offset even under the action of friction. The suction pump is particularly simple in that the pump chamber consists of an elastic wall, a head and a bottom. The bottom portion is located above the inverted filling head and is provided with an inflow valve which, when the pump chamber is stretched, draws the medium from the storage container into the pump chamber and locks when the pump chamber is compressed. The head is provided with a discharge valve that dispenses the medium when the pump chamber is compressed and closes when the pump chamber is stretched. In particular, other functional parts may be provided on the head or the bottom to foam the medium or to prevent the medium from dripping after the dispensing is completed. In a preferred embodiment of the suction pump of the present invention, the guide member acts on at least the suction pump head and the bottom of the suction pump is fixed relative to the dispenser housing. Further, the guide member ensures that the suction pump head moves in the pump priority direction with respect to the fixed bottom of the suction pump. By installing the guides and guiding the guides in only one direction, the function of the dispenser is ensured. In the above-described dispenser unit, the guide member can avoid the offset caused by the mounting of the filling head, and thus the guiding device only provides a bracket that reacts with the mounting motion. Therefore, during the installation of the filling head 201008541 from the front to the rear wall of the casing, the guide must avoid the bellows head toward the rear wall. In order to improve the functional safety, it is best to guide the fruit head throughout the running process. The pump head should be guided throughout the path of travel and perpendicular to the pump priority. The head of the fruit sucker may have a convex edge which can be inserted into the device, especially the "capture clip", during installation into the dispenser housing. The Φ' edge can be a contact through which the insertion device can be prevented from damaging the elastic wall. Depending on the configuration of the wall, the head of the spring may be disc-shaped or, alternatively, may have a disk-like portion permeable to the spacer block that is connected to the interface between the pump head and the resilient wall. The guide can be either an inner guide or an outer guide. If the guide is an outer guide, the suction body is 'the body' and the chestnut chamber is placed on the (four). The easiest way is to form the body from the bottom, and the guides are guided in the form of guides through the box eyes provided at the head and from the bottom toward the head. In addition, the 'guides can also be formed by the wall of the pump body, which can be squeezed together like an accordion in a telescopic manner. In addition, the head may also have a piston-shaped outer edge 'the edge is in the columnar fruit body, and is led to the fruit priority direction, the same, 'the other part of the head, that is, the piston part of the head away from the chestnut chamber, Connected to the device and the portion from the cylindrical region at all positions of the head - may be a discharge tube, and the discharge tube is provided with a disc-shaped edge of the lateral dog at the bottom thereof. On the edge. 7 201008541 Alternatively, the head portion may have a cylindrical wall portion projecting upwardly from the bottom direction, the wall portion being connected to a disk portion which in turn is connected to the elastic wall of the pump chamber. Also, the cylindrical wall of the head faces the pump body or the bottom. In order to ensure the safety of the suction pump during transportation, the bottom of the suction pump of this embodiment can be moved to the conveying position, and at this time, the height of the cylindrical ring body is at least equivalent to the height of the pump chamber, so that the bottom can be pushed to the ring. The upper edge of the body, and finally the entire pump chamber is placed in the cylindrical ring. Alternatively, the suction pump having the delivery safety device may have a bell-shaped bottom portion extending in the direction of the head, and the elastic wall of the pump chamber is connected to the lower portion of the bell portion at the bottom. To form a delivery safety device, the resilient portion of the pump chamber wall is inverted inwardly with the head to bring the head and bottom closer together and to disable the pump. During the installation process, the insertion aid can also not only clamp one edge of the head to connect it with the operating device, but also disable the transport safety device during the loading process and push it in for the first time. During the process, the head is operated for a long distance, so that the elastic wall portion of the pump chamber is turned outward again. An advantage of the structure of the invention is that it forms a guide through the push rods of the inflow valve and the discharge valve. The inflow valve and the discharge valve are respectively provided with a push rod having a valve member such as a sealing diaphragm. The push rod is longer than the valve member portion, and is provided with a guide portion at the excess portion, the guide portion is guided by the guide member, and, according to whether the push rod is the push rod of the inflow valve or the push rod of the discharge valve, the guide member can be respectively located at the pump 201008541 Body, pump head or bottom. Further, the corresponding portion of the guiding device is preferably provided with a box, the guiding portion being located in the box eye and movable in the preferential direction of the pump. In another preferred embodiment of the pump invention, the inflow valve and the discharge valve may be provided together with a push rod, preferably the push rod passing through the center of the pump chamber, and the switch member is on the side of one of the valves The push rod is fixedly connected and is movably supported on the push rod on the side of the other. For example, the switch member can be fixedly connected to the push rod on the side of the discharge valve, and on the side of the inflow valve, the movable type can be placed on the push rod, so that the inflow valve and the discharge valve can be operated under pressure alone. When compressing the corrugated valve, the push rod can be inserted into the storage container or into the middle of the suction pump and the storage container. The above embodiment can be made in that the switch member of the inflow valve can have a tubular portion for the longitudinal guide pusher. By setting the limit element, the relative movement of the switch member in the direction of the push rod can be restricted, and at the same time, the entire compression movement of the ripple pump can be determined, thereby preventing the elastic wall material from being damaged by excessive deformation. In this configuration, the push rod is preferably supported by a valve seat of one or two valves, i.e., through a valve seat of the inflow valve or the discharge valve. Alternatively, the push rod can be movably supported in the pump chamber or in the pump chamber to form an (additional) guide. The discharge valve can be provided with a push rod in all embodiments, the push rod extending in a direction away from the pump chamber and having a disc-shaped region at the bottom, through which the push rod and the dispenser can be operated The devices are connected. Of course, it is not necessary to provide a disc-shaped area, and the push rod can also be connected to the operating device of the dispenser through the device of other mechanical type 9 201008541. The operating device of the present invention, like the operating device described in the previous invention, can be any type of valve operating device, particularly a mechanical press or an electric drive that is triggered by a sensor. The push rod of the discharge valve extending from the pump chamber extends away from the pump chamber and is preferably hollow cylindrically shaped to deliver the medium to the outlet through the push rod, where the push rod forms a medium output passage. In order to prevent the excess medium from dripping, whether the output passage is formed by a push rod or a separate passage, a seal or a valve member may be additionally provided in the output passage, and a sealing diaphragm may be considered. The dispenser unit of the present invention includes a housing into which the filling head can be placed. As previously mentioned, the filling head consists of a storage container and a suction pump disposed therein. The suction pump is a bellows pump and has a head that is movable toward the bottom to transmit an operating force, either through an electric drive or through a push button. At the same time, the suction pump also has a guide to ensure that the head moves in the preferred direction of the pump. Normally, the filling head and the suction pump are placed down in the housing so that the pump is preferentially oriented in a downward vertical direction, and finally the discharge medium is dripped directly from the discharge direction to the user's hand. Preferably, the dispenser unit has an insertion device formed by a "capture clip" which is a u-shaped clip having a circular or curved angle for capturing when the filling head is placed in the dispenser unit. The clip grips the edge of the active portion of the suction pump from behind, especially the edge of the head finger. The insertion device is in turn mechanically coupled to the housing, whereby the movement of the suction pump can be moved by the movement of the operating device with the 201008541. Thereby, the pump chamber is compressed and the medium is discharged from the pump chamber by the pump in a preferential direction. If the suction pump has the above-described delivery safety device, the dispenser unit may additionally be provided with an insertion aid which acts with the other insert on the movable portion of the suction pump. The additional insertion aid can act on the first section to traverse the elastic wall of the pump chamber to disable the delivery safety device. During the loading process, the insert of the peripheral device is assisted along with another insertion. The guide surface of the device® slides and moves the head to the position of use. Alternatively, the peripheral insertion aid can be connected in series with the first insertion aid, the first device "captures the clip" and the capture clip has an arcuate angle that is preferentially curved toward the pump. Moreover, the suction pump can have a leak protection, which is located behind the pump chamber and can be constituted by a sealing membrane. For example, the sealing membrane can be composed of several valves, such as three valves, like a heart valve, and the valve is In the quiescent state, the mergings merge into a closed loop; and under the action of the discharge medium pressure, they are separated from each other in the discharge direction. Further, the valve is in turn connected to the wall of the drainage channel through the edge, wherein the edge is isolated from the other valves, and the valve overlaps its corresponding edge when in a resting state. • When the media passes through the seal, the folded valve opens toward the wall to allow the media to pass through. When the pressure is reduced, the valve is closed again under the elastic restoring force. By moving in the opposite direction of the flow, the medium is reabsorbed back into the discharge passage, thereby preventing excess media from dripping. 201008541 Of course, 'other methods can also be used to form - leak protection or similar functions, such as suction-type reflow in the discharge channel, or tricks, or cymbals'. These devices act by springs in the closed direction. And open it through the dishes. [Embodiment] As shown in Fig. 1, the dispenser unit of the present invention has a dispenser housing and the dispenser unit can be filled by a filling head. The filling head consists of a chestnut and a storage container 2, wherein the county is located inside the storage container. Further, the sucking fruit is a bellows having a head 3, a bottom 4 and an elastic wall 5' which is located between the head 3 and the bottom 4. Figure 2 is an enlarged view of the structure of the county of the present invention, wherein the suction is a bellows pump, and has a head 3 which is disposed relative to the dispenser housing and the head 3 is The elastic wall 5 is connected to the bottom 4. In order to prevent the movable head 3 from being displaced to the side, a guide 8 is additionally provided, and the head 3 is guided via the guide 8. And the material member 8 is connected to the bottom portion 4, and the other portion passes through the head portion 3 through the box of the head portion 3. In this way, the head 3' is prevented from loading the filling head into the dispenser housing! When offset, the direction of loading is offset to ensure reliable insertion and to avoid failure of the corrugated valve. Fig. 3 is another structural view of the corrugated valve of the present invention, in which the guide 8 is a built-in guide 8. Further, the inflow valve has a common push rod 6 at the discharge valve. Moreover, the valve member of the bellows pump flowing into the valve is placed in a sleeve, and the 12 201008541 sleeve is disposed on the common push rod 6, so that the inflow valve and the discharge valve can independently perform their functions. The bellows described above is additionally provided with a hollow cylindrical push rod 6, which in turn has a side air inlet which is located in the pump chamber. Thereby, when the elastic wall 5 is compressed, the medium in the pump chamber 7 is transmitted through the side air inlet and then passed through. The hollow push rod 6 is discharged in the pump priority direction V.
