Description of the invention: [Technical field to which the invention pertains] The present invention relates to an ink guiding device, and more particularly to an ink jetting ink guiding device which is manufactured in a continuous ink supply system. Soil [Prior Art] - In general, 'inkjet printers are popular with consumer A because they are easy to operate and can be printed on a variety of Hemo media, but inkjet printers use - after the day' The ink E needs to be replaced because the ink is out of ink. The current common replacement method is to discard the old ink and then Amnon's new ink E to provide ink, which not only causes waste of ink, but also The cost of the ink E is intangible and invisibly increases the user's overhead. In order to save printing costs and avoid capital, the continuous ink supply system that has closed the ink cartridges has been created. The existing continuous ink supply systems are external continuous ink supply systems, which are arranged outside the ink jet printer - the ink supply container, and the ink supply container and the ink jet printer (4) are connected by a line. The principle of "true" ink will make the ink supply from the ink supply container to the ink, and then visually observe the ink consumption and ink consumption and timely replenish the ink into the ink supply container to achieve continuous uninterrupted ink supply. For the purpose of ink supply. ' However, the above continuous ink supply system has many limitations and inconveniences in use. The height of the first ink supply container must be placed on the same plane as the inkjet printer and the ink liquid of 仏墨谷益The surface must be slightly lower than the nozzle of the inkjet printer to prevent the ink from overflowing due to the excessive hydraulic pressure from the ink supply container. However, after standing for a while, the ink will often be due to its =ic The liquid level is relatively the same and is returned to the ink supply container, which not only seriously affects the ink supply complaint, but also wastes _quantitative ink when re-use, so that the ink squeezing force can restore balance and smoothly supply ink.

包含塞蓋容置端141、供墨室142及套環置入口 143。而 彈性元件12可為一彈簧，但不以此為限，任何具有彈力 之元件，皆可用於本案作為彈性元件12。 請參閱第一圖⑻並配合第一圖（d)，栓塞11為一具有 彈性之軟性材質，例如橡膠，但不以此為限，且其包括一 塞蓋端111、連接柱112及卡合端113,其中塞蓋端111及 卡合端113係位於連接柱112之相對兩側，且塞蓋端111 具有第一側面Π11及第二側面1Π2，其係位於該塞蓋端 111之兩相對側，其中第一側面1111係鄰接於該墨水匣1 内部之墨水腔10並與該墨水腔10之墨水或泡綿（未圖示） 12 200808562 相接觸’且第一側面1 η 1的多 妁表面更具有一凹槽1113，用 以於組=至谷置結構14上時軸向旋轉調整检塞u之角 度’而第二側面1112係相對於第一側Φ 1111並與連接柱 112連接’此外，塞蓋端lu之第一側面！出的面積實質 上大於第二側面1112之面積，於本實施例中，塞蓋端⑴ 為0錐台，不以此為限’換言之，任何第—側面仙 面積大於第二側面1112面積之形狀’皆可作為本案之塞蓋 • 端1U ’以便組裝於容置結構Μ之塞蓋容置端141時藉^ 面積較大的第-側面仙提供—個良好的封閉的作用。 請再參閱第-圖⑷，栓塞Η的卡合端U3係位於連 接柱112相對於塞蓋端lu之另一端，包括複數個反彈塊 1131與一底座1132，其中底座1132之寬度li小於其長 度L2’於本實施例中，底座脱實質上為擴圓形，但不 以此為限，任何長寬具有差異之形狀，例如長方形等，皆 可作為本案底座1132之形狀。而複數個反彈塊 1131之整 • 體輪廓的寬度實質上與底座1132之寬度L1相同但長度略 小於底座1132之長度L2，且底座1132及反彈塊1131兩 者之面積皆小於塞蓋端111，又反彈塊1131之厚度較底座 1132為薄，以便栓塞n沿軸向朝墨水腔1〇方向進行位移 時可彎曲變形（如第二圖所示）。 請參閱第一圖⑻並配合第一圖（c)，栓塞u之塞蓋端 111及卡合端113係利用連接柱H2相連，於本實施例中， 連接柱112為一直徑實質上等於卡合端113之底座n32 見度L1之圓柱，但不以此為限。而連接柱112位於其軸 13 200808562 心處具有第一流道1121 (如第一圖（c)所示），而在接近卡合 端113處具有一第二流道1122,於本實施例中，第一流道 1121大致為圓錐狀，但不以此為限，且第一流道1121係 軸向延伸貫穿卡合端113,而第二流道1122係平行於卡合 端113之底座1132長度L2方向且垂直軸向地貫穿連接柱 112並與第一流道1121相通以構成一 T形流道。此外，在 第一流道1121中延軸心設有一剛性材質之抵頂柱1123, _ 用以於墨水匣1安裝至墨水匣承載座（未圖示）上時配合一 外來結構，例如頂針結構，使第一流道Π21及墨水匣承 載座間得以疏通，而在第一流道1121之侧壁上則具有凸 出之抵頂面1124(如第一圖（c)所示），其中抵頂面1124係 用以承受外來作用力以使栓塞11產生一軸向位移（如第二 圖所示)。 請再參閱第一圖（a)並配合第一圖（d)，套環13大致上 呈圓柱狀，且為具彈性之軟性材質，例如橡膠，但不以此 φ 為限。套環13具有第一側面131、開口 132、卡合端容置 槽133及第二侧面134,其中套環13之第一侧面131包括 複數個卡固塊1311，以卡固彈性元件12。而套環13更具 有開口 132,其係位於第一侧面131上並横越第一侧面 131，且開口 132之兩相對侧壁上具有凸塊1321，凸塊1321 之位置係對應於栓塞11之第二流道1122。此外，開口 132 之寬度L3實質上等於栓塞11之卡合端113的底座1132 寬度L1且小於底座1132之長度L2，而卡合端容置槽133 之寬度L4實質上約等於卡合端113之底座1132之長度 14 200808562 L2，換言之，開口 132之寬度L3小於卡合端容置槽133 之寬度L4,因此開口 132及卡合端容置槽133可構成一倒 T形的空間，而卡合端容置槽133之高度則是大約等於整 個卡合端113之厚度，是以栓塞11軸向旋轉至底座1132 寬度L1與套環13之開口 132寬度L3對齊時，整個卡合 端113可穿過套環13之開口 132進入卡合端容置槽133， 並在栓塞11實質上軸向旋轉90°後卡合且容置於卡合端容 _ 置槽133中，於此同時，栓塞11之第二流道1122則與套 環13開口 132上之凸塊1321密合，以封閉第二流道1122。 此外，套環13之第二侧面134的周圍具有複數個定位塊 1341而轴心處有一出墨口 1342(如第一圖（d)所示），其中定 位塊1341係用以將套環13定位於墨水匣1上，而出墨口 1342則用以釋出來自第一流道1121之墨水。 接著請參閱第一圖（b)並配合第一圖（c)及（d)，墨水匣1 内具有墨水腔1〇及一容置結構14,容置結構14包含第一 φ 端面及第二端面，係用以容置栓塞11、彈性元件12及套 環13，而容置結構14更包括塞蓋容置端141(第一端面）、 供墨室142及套環置入口 143(第二端面），其中塞蓋容置端 141鄰近墨水腔10且具有一隔板1411，並透過位於隔板 1411上之供墨口 1412連通墨水腔10及供墨室142，而供 墨口 1412其形狀實質上與栓塞11卡合端113相同且小於 栓塞11之塞蓋端111，此外，塞蓋容置端141之形狀實質. 上與栓塞11之塞蓋端Π1相同，且其側壁上具有複數個凹 陷之引流槽1413，因此當栓塞11之卡合端113及連接柱 15 200808562 112穿過供墨口 1412而使塞蓋端111容置於塞蓋容置端 141時，可藉由塞蓋端111確實地封閉塞蓋容置端141之 供墨口 1412及引流槽1413,避免墨水自墨水腔10經由引 流槽1413及供墨口 1412流入供墨室142。供墨室142相 對於塞蓋容置端141之另一端則為套環置入口 143，而供 墨室142及套環置入口 143於垂直軸向之截面積大小實質 上與套環13相等，且套環置入口 143之周圍具有複數個 _ 相對應於套環13定位塊1341之定位口 1431，以定位套環 13並避免套環13的軸向轉動。 請參閱第一圖（c)並配合第一圖（d)，如圖所示，首先提 供具有墨水腔10及容置結構14之墨水匣1以及栓塞11 與套環13,並將套環13及彈性元件12由墨水匣1之容置 結構14的套環置入口 143置入供墨室142中，且將套環 13固定於墨水匣1上，其中彈性元件12係藉卡固塊1311 固定於套環13之第一侧面131上，而套環13則藉由其定 φ 位塊1341與套環置入口 143之定位口 1431相配合，以避 免套環13軸向轉動。於本實施例中，套環13係以旋轉之 方式固定於墨水匣1上，當套環13之位置固定後，此時 彈性元件12便大致抵頂於塞蓋容置端141的隔板1411， 以提供一個緩衝及牵引的功能，且由於套環置入口 143於 垂直轴向之截面積大小實質上與套環13相等，因此套環 13可封閉套環置入口 143(亦即第二端面）及供墨室142而 避免供墨室142的墨水自套環置入口 143滲出至墨水匣1 外0 16 200808562 另一方面，栓塞11需轴向旋轉調整至其卡合端113 對準容置結構14之塞蓋容置端141的供墨口 1412，由於 供墨口 1412之形狀等於卡合端113之底座1132且小於塞 蓋端111，又連接柱112之直徑實質上等於卡合端113之 底座1132的寬度L1，因此僅卡合端113及連接柱112可 穿過供墨口 1412進入供墨室142，而塞蓋端111則留置於 墨水腔10之一側。當卡合端113進入供墨室142之一定 _ 距離時，會與套環13相接觸，而由於卡合端113之底座 1132寬度L1大致等於套環13之開口 132寬度L3(如第一 圖（a)所示），因此需將栓塞11轴向旋轉調整至適當位置， 亦即令卡合端113之底座1132的寬度L1對準開口 132之 寬度L3，方可使卡合端113穿過套環13之開口 132而進 入卡合端容置槽133,接著利用塞蓋端111之第一側面1111 之凹槽1113再度軸向轉動調整栓塞11，使卡合端113之 底座1132的長度L2平行於套環13之卡合端容置槽133 φ 的寬度L4,由於底座1132的長度L2大致等於卡合端容置 槽133的寬度L4且大於開口 132之寬度L3，且卡合端容 置槽133之高度大致等於卡合端113之厚度，因此整個卡 合端113可容置於卡合端容置槽133中並與套環13之開 口 132產生十字型的卡固效果，故栓塞11與套環13得以 連結並避免脫落，同時亦使栓塞11之塞蓋端111恰好容置 於塞蓋容置端141(亦即第一端面）中，且栓塞11之第二流 道1122與套環13之凸塊1321相互卡合。 請參閱第一圖（d)，當栓塞11之卡合端113穿過供墨 17 200808562 口 1412而容置並卡合於套環13之卡合端容置槽133後， 卡合端113之反彈塊1131及底座1132分別與卡合端容置 槽133之兩相對側面接觸，而栓塞η之塞蓋端ηι則容置 於塞蓋容置端141中，並藉由塞蓋端ln之第一侧面lln 及第二侧面1112分別密封塞蓋容置端141及其供墨口 1412，使墨水腔1〇的墨水無法藉由供墨口 1412進入供墨 室142;同時，由於栓塞u之連接柱112的第二流道η]] _ 亦藉由套環13之凸塊U21封閉，因此供墨室142中的墨 水亦無法自第二流道1122進入第一流道1121而由套環= 之出墨口 1342流出至墨水g i外部。故此一設計確實地 封閉了墨水匣1，使墨水Ε !在停止供墨的狀況下不致於 / Μ㈣第二圖’其係為本案第—較佳實施例連續供墨 糸統，水ϋ之導墨裝置於導墨狀態下之示意圖。由於本案 之才王基η及套壤13係為兩個獨立之構件，故當墨水匿1

端容置槽133的一侧彎曲變形，而栓塞11之第二流道1122 則會脫離套環13之凸塊1321而與供墨室142相連通，且 栓塞11之塞蓋端111亦會因位移而與塞蓋容置端141產生 一間距，使塞蓋端111之第二侧面1112不再封閉塞蓋容置 端141之供墨口 1412，是以墨水腔10中的墨水可如第二 圖之虛線箭頭所示，經由塞蓋容置端141與塞蓋端111之 間距藉由引流槽1413及供墨口 1412流至供墨室142中， 再透過栓塞11之連接柱112上的第二流道1122流入第一 流道1121，最終則經由套環13之出墨口 1342或經由銜接 於第一流道1121中之墨水匣承載座上的頂針結構（未圖示） 而將墨水腔10中的墨水導流而出，以完成導墨的動作。 同樣地，如第一圖（d)所示，當該外來結構所提供之作 用力消失時，由於栓塞11之卡合端113的反彈塊1131具 有彈力，因此反彈塊1131會還原成原形，而使卡合端113 φ 因反彈塊1131的彈力作用而退回至套環13之卡合端容置 槽133中，同時亦將栓塞11之塞蓋端111拉回容置結構 14之塞蓋容置端141，因此可藉由栓塞11之塞蓋端111 的第一側面1111阻斷塞蓋容置端141，並藉由塞蓋端111 之第二侧面1112阻斷塞蓋容置端141的供墨口 1412，故 墨水腔10中的墨水便無法再進入供墨室142中，此為第 一斷墨處。當然，在栓塞11之反彈塊1131的彈力帶動下， 塞蓋端111復位至塞蓋容置端141的同時，栓塞11之連接 柱112上的第二流道1122亦與套環13上的凸塊1321再度 19 200808562 卡合，使供墨室142中的墨水無法藉由第二流道1122經 第一流道1121而輸出，此為第二斷墨處。此外，外來作 用力的消失會相對於套環13產生一牵引的力量而將套環 13上的屏障物，例如一薄膜，牽引回原位或凸起，因此亦 可當作一斷墨處。是以墨水匣1可利用該些斷墨處阻斷墨 水的流出，以，避免殘存於墨水腔10中的墨水滲溢所造成 的污染或浪費。 綜上所述，本案適用於連續供墨系統之墨水匣導墨裝 置於導墨狀態時，係利用一外力作用抵頂栓塞之抵頂面， 由於栓塞之反彈塊為具有彈性之軟性材質，因此可變形使 栓塞得以產生軸向位移，使塞蓋端離開塞蓋容置端且第二 流道脫離凸塊之卡固，故可同時開放容置結構之供墨口及 栓塞之第二流道，因此墨水腔中的墨水得以經由供墨口進 入供墨室再依序經第二、第一流道並經由套環之出墨口出 墨。 而墨水匣之導墨裝置於欲停止供墨時，可藉由除去外 來作用力進行斷墨，且隨著外來作用力的消失，墨水匣内 部之栓塞會因其卡合端之反彈塊的彈力作用還原而歸位 至套環之卡合端容置槽中，同時帶動栓塞之塞蓋端回到塞 蓋容置端，並使栓塞之第二流道與套環之凸塊再度卡合， 因此可利用塞蓋端之第一及第二侧面分別密封塞蓋容置 端及供墨口所形成的第一斷墨處以及栓塞之第二流道與 套環之凸塊緊密結合所形成的第二斷墨處來阻斷墨水腔 中的墨水流出，故可確實的密封墨水匣端，此結構不但可 20 200808562 防止漏墨污染喷墨印表機内部，亦可避免墨水的浪費。 此外，由於本案墨水匣具有良好的斷墨機制，相對地 簡化了墨水匣補墨的難度，例如使用者可自墨水匣承載座 上卸下墨水匣補墨而不會有漏墨之問題，故無須如習知技 術般經由複雜的管線進行補墨，因此不會有管線鬆脫影響 供墨之困擾，亦不會因管線的纏繞影響喷墨印表機之外 觀。又透過本案之導墨結構的設計，墨水匣可重複多次利 用，不但避免了貨源的浪費，亦節省了使用者的開銷，使 墨水匿之使用更臻完備，是以本案極具產業之價值，爰依 法提出申請。 縱使本發明已由上述之實施例詳細敘述而可由熟悉 本技#之人士任施匠思而為諸般修飾，然皆不脫如附申請 專利範圍所欲保護者。 200808562 【圖式簡單說明】 第一圖（a):其係為本案第一較佳實施例之栓塞、彈簧及套 環之結構示意圖。 第一圖（b):其係為本案第一較佳實施例之墨水匣容置結構 之透視圖。

(4) The second diagram 'is the first embodiment of the present invention - the preferred embodiment of the continuous ink supply system Schematic diagram of the ink device in the state of ink guiding. Since the Wang Ji η and the Tuo Lin 13 series of the present case are two independent members, when the ink is blocked, the ink guiding device is to be assembled onto the ink bearing seat (not shown) for the wing to be utilized - the external structure For example, the ink is needle: :; 3 is for the production of T: the force is applied after 11 to make the remainder: the produced axial displacement to release the ink in the ink chamber 1〇. = 'When one of the external forces (solid arrow) passes through the cavity in the first flow channel (10), the movement occurs in the direction away from the collar ', that is, toward the engagement end of the ink on the raft base 11 The bounce block 18 200808562 1131 is a soft material and has elasticity, so that it can be bent and deformed along one side of the engaging end receiving groove 133 of the collar 13, and the second flow path 1122 of the plug 11 is disengaged from the collar 13 The bump 1321 is in communication with the ink supply chamber 142, and the plug end 111 of the plug 11 is also displaced from the cap receiving end 141 by displacement, so that the second side 1112 of the cap end 111 is no longer sealed. The ink supply port 1412 of the occlusion cover receiving end 141 is such that the ink in the ink chamber 10 can be as shown by the dotted arrow in the second figure, and the distance between the accommodating end 141 and the sluice end 111 via the sluice cover is through the drainage groove 1413. And the ink supply port 1412 flows into the ink supply chamber 142, and then flows into the first flow path 1121 through the second flow path 1122 on the connecting post 112 of the plug 11, and finally passes through the ink outlet 1342 of the collar 13 or through the connection The ejector structure (not shown) on the ink cartridge holder in the first-stage track 1121 directs the ink in the ink chamber 10 To complete the operation of the ink guide. Similarly, as shown in the first figure (d), when the force provided by the foreign structure disappears, since the rebounding block 1131 of the engaging end 113 of the plug 11 has an elastic force, the rebounding block 1131 is restored to the original shape, and The engaging end 113 φ is retracted into the engaging end receiving groove 133 of the collar 13 by the elastic force of the rebounding block 1131, and the plug end 111 of the plug 11 is also pulled back to the cover of the receiving structure 14 The end 141 can be blocked by the first side 1111 of the plug end 111 of the plug 11, and the cover end 141 can be blocked by the second side 1112 of the cover end 111. The ink port 1412, so the ink in the ink chamber 10 can no longer enter the ink supply chamber 142, which is the first ink break. Of course, under the elastic force of the rebounding block 1131 of the plug 11, the plug end 111 is reset to the capping end 141, and the second channel 1122 on the connecting post 112 of the plug 11 is also convex with the collar 13. Block 1321 again 19 200808562 is engaged, so that the ink in the ink supply chamber 142 cannot be output through the second flow path 1122 through the first flow path 1121, which is the second ink break. In addition, the disappearance of the external force will cause a pulling force relative to the collar 13 to pull the barrier on the collar 13, such as a film, back into place or bulge, and thus can also be used as a break. Therefore, the ink cartridge 1 can be used to block the outflow of the ink by the ink breakage, so as to avoid contamination or waste caused by the overflow of the ink remaining in the ink chamber 10. In summary, the present invention is applicable to the ink supply device of the continuous ink supply system in the state of guiding the ink, and an external force is applied to the top surface of the plug, since the rebounding block of the plug is a soft material having elasticity, The deformation can cause the plug to generate axial displacement, so that the plug end is separated from the plug cover end and the second flow path is disengaged from the bump, so that the ink supply port of the accommodating structure and the second flow path of the plug can be simultaneously opened. Therefore, the ink in the ink chamber can enter the ink supply chamber through the ink supply port and then sequentially pass through the second and first flow paths and discharge the ink through the ink outlet of the collar. When the ink guiding device of the ink cartridge stops the ink supply, the ink can be broken by removing the external force, and as the external force disappears, the plug inside the ink cartridge will be elastic due to the rebounding block of the engaging end. The action is restored and returned to the engaging end receiving groove of the collar, and the plug end of the plug is brought back to the receiving end of the plug cover, and the second flow channel of the plug is re-engaged with the protruding block of the collar. Therefore, the first and second sides of the plug cover can be used to seal the first cover of the cover end and the ink supply port, and the second flow path of the plug is tightly combined with the protrusion of the collar. The second broken ink breaks the ink outflow in the ink chamber, so the ink end can be sealed reliably. This structure can not only prevent the ink from polluting the inside of the inkjet printer, but also avoid the waste of ink. In addition, since the ink cartridge of the present invention has a good ink-breaking mechanism, the ink filling ink is relatively simplified, for example, the user can remove the ink from the ink cartridge carrier and fill the ink without leaking ink. It is not necessary to refill the ink through complicated pipelines as in the prior art, so there is no problem that the looseness of the pipeline affects the ink supply, and the appearance of the inkjet printer is not affected by the entanglement of the pipeline. Through the design of the ink guiding structure of the case, the ink cartridge can be repeatedly used, which not only avoids the waste of the source of goods, but also saves the user's overhead, and makes the use of the ink more complete, which is the industrial value of the case. , 提出 apply in accordance with the law.
