按，習用之「液體抽吸裝置之改良結構」如中華民國專利申請案號第０９３２０９０００，一種液體抽吸裝置之改良結構，係由外桶、桶蓋、唧筒、活塞、導氣桿及作用桿組成；其中：
外桶，為一中空之ㄩ形桶體，於其上端預設一抽吸孔
，此抽吸孔可供連結有抽吸管之封蓋嵌入者；
桶蓋，為螺設於外桶上方且上端面中央設有提把之蓋體，此桶蓋之底面中心設一凸塊，此凸塊之中心上、下方分別設以一套環及一豎向之導氣槽，另桶蓋之提把下方設一貫通導氣槽上段之橫向導氣孔，於橫向導氣孔之中段預設一豎向穿孔，且豎向穿孔下方吊設一浮球者；另提把對應上述套環之位置預設一穿管孔者；又橫向導氣孔之外端預設一嵌凹槽，此嵌凹槽可供一固件環嵌入且迫緊定位，其固件環之中心可供一穿桿由內向外穿貫，且穿桿之穿貫端套組有彈性體，並作用桿外端復與一調整鈕螺合者；
唧筒，係內壁上端可與桶蓋底面之凸塊螺合之中空筒體，且唧筒之內壁下端組固一封筒環者；
活塞，係上、下活動於唧筒內部之氣體抽真空作用構造，於活塞中心穿管孔四周環設有數逆止閥者；
導氣桿，係內部預設導氣孔之氣體導出桿，其導氣桿下端穿貫活塞之穿管孔復與螺帽螺合，且導氣桿之內壁下端設一逆止閥，另導氣桿之上端由下向上穿貫桶蓋之穿管孔者；
其特徵在於：
作用桿，係中段與導氣桿頂端Ｔ形固結之中空桿體，於其中空部分形成一後半段可與導氣桿連通之空氣通道，此空氣通道前端開口乃套固有一進氣嘴，此進氣嘴之上端設有一可扳轉之控制開關，且於該空氣通道中段形成一頸縮段，該頸縮段之另一側則可供一降壓閥配合迫緊環容置塞固，其中該降壓閥中央預設有一與空氣通道相連通且內徑較空氣通道細之閥孔，此閥孔乃呈現前端窄、後端寬之狀態，且該空氣通道之末端則套設一消音器者；
藉由上述作用桿與導氣桿之配合，可兼具手動、氣動雙重切換選擇之功能，進而達到快速抽吸與缺乏動力源下仍可操作抽吸液體之功效增進者。
其上述所述之「液體抽吸裝置之改良結構」，該使用作動的過程中，主要的氣體流動皆須經由作用桿內的結構來流通，此在操作使用上較為不便，且容易阻礙操作，而操作過程中產生的作用係直接與動作同步，故如操作不當則無挽救機會，為其有待改良之弊端。According to the "improved structure of the liquid suction device", as in the Republic of China Patent Application No. 093209000, an improved structure of the liquid suction device is composed of an outer tub, a bucket lid, a cylinder, a piston, a gas guide rod and a rod Composition; among them:

本發明液體吸抽設備，於實施將外部流體抽吸入時，〔請參閱第二圖〕將上切換閥（２）與下切換閥（３）分別拉出封蓋（１２）與底座（１３）外，以令上孔道（１２１）可直接與上活動孔（１２２）相通，而下孔道（１３１）則可直接與下通孔（１３３）相通，繼以俾操作桿（５）由下向上拉提，而在拉提的同時，由於塞體（５３）瞬間向上拉，使唧桶（４）內塞體（５３）下方部分的空間瞬間成真空狀態，進而使桶身（１１）內的氣體經由上活動孔（１２２）至上孔道（１２１）進入中心孔（１２４）流進唧桶（４）內，該流體再通過逆止閥（５４）往底座（１３）排出，經此將操作桿（５）反復上下作動，假設接頭（７２）處預先銜接有他端容器，繼可一併帶動他端容器內的液體被桶身（１１）內的壓力而經由抽吸管（７１）被吸入，亦或，可在桶身（１１）內的氣體完全被排出使桶身（１１）內成真空狀態，再令接頭（７２）銜接他端容器，來將他端容器內的液體一併被桶身（１１）內的壓力而經由抽吸管（７１）被完全吸入桶身（１１）內，進以達成抽吸入的作動者。
本發明液體吸抽設備，於實施將內部流體逼壓出時，〔請參閱第三圖〕假設接頭（７２）處預先銜接有他端容器，首先將上切換閥（２）與下切換閥（３）分別按壓入外桶（１）之封蓋（１２）與底座（１３）內，以令上通孔（１２３）可通過上環孔（２２）進入上穿孔（２３）與上孔道（１２１）相通，而下孔道（１３１）則可通過下穿孔（３３）進入下環孔（３２）至下活動孔（１３２）與導管（６）相通，繼以俾操作桿（５）由上向下壓，令桿體（５２）推動塞體（５３）在唧桶（２）內向下移動，藉由塞體（５３）可讓唧桶（２）內的氣體往底座（１３）方向移動，而該氣體經由下孔道（１３１）通過下穿孔（３３）進入下環孔（３２）至下活動孔（１３２），最後由導管（６）把氣體充至桶身（１１）內，而由於在塞體（５３）向下移動的同時，在塞體（５３）上方的唧桶（４）內空間可形成一壓力來俾使封蓋（１２）外處的氣體經由上孔道（１２１）通過上穿孔（２３）進入上環孔（２２），進而由上通孔（１２３）處被吸入，繼之，將操作桿（５）反復上下作動，可讓氣體不斷地充至桶身（１１）內，且氣體自然地係存在於桶身（１１）內上部，進而使氣體在桶身（１１）內由上向下漸漸逼迫流體經由抽吸管（７１）經接頭（７２）而導出他端的容器內，以達成逼壓出的作動，且當若流體導出速度較慢，而氣體充至桶身（１１）內的速率過快而導致氣體於桶身（１１）內的壓力過大時，洩壓體（８）則可同時受壓力影響向上擠壓，繼使氣體可暫時經由洩壓體（８）上端處的縫隙排出，藉以達到使用上的安全功效，而其洩壓體（８）在桶身（１１）內恢復正常壓力時便可回復至原本位置以供正常操作者。
本發明液體吸抽設備，其優點在於，由於該抽吸設備在使用時必須先同時切換上切換閥（２）與下切換閥（３）二者，之後才可對此設備進行抽吸的作用，進而形成一道使用前的安全手續，而此外，由於流體的流動皆係在外桶（１）內進行，故在使用上亦較為順手便利者。
綜上所述，當知本發明具有新穎性，且本發明未見之於任何刊物，當符合專利法第２１、２２條之規定。
唯以上所述者，僅為本發明之一較佳實施例而已，當不能以之限定本發明之範圍。即大凡依本發明申請專利範圍所作之均等變化與修飾，皆應仍屬本發明專利涵蓋之範圍內。The invention relates to a liquid suction device, (see the first figure) mainly comprising:

The liquid suction device of the present invention, when the internal fluid is forced out, [see the third figure] assumes that the joint end (72) is pre-attached with the other end container, firstly the upper switching valve (2) and the lower switching valve ( 3) Pressing into the cover (12) and the base (13) of the outer tub (1) respectively, so that the upper through hole (123) can enter the upper through hole (23) and the upper hole (121) through the upper ring hole (22). The bottom tunnel (131) can pass through the lower perforation (33) into the lower ring hole (32) to the lower movable hole (132) to communicate with the conduit (6), and then the upper operating lever (5) is pressed from top to bottom. , the rod body (52) pushes the plug body (53) to move downward in the bowl (2), and the gas in the bowl (2) is moved to the base (13) by the plug body (53), and the The gas enters the lower ring hole (32) to the lower movable hole (132) through the lower perforation (33) through the lower perforation (131), and finally the gas is filled into the barrel (11) by the conduit (6), and (53) Move down At the same time, a space may be formed in the space inside the bowl (4) above the plug body (53) so that the gas outside the cover (12) enters the upper ring hole through the upper hole (23) through the upper hole (121) ( 22), and then sucked in by the upper through hole (123), and then the operating lever (5) is repeatedly actuated up and down, so that the gas is continuously charged into the barrel (11), and the gas is naturally present in the barrel. The upper part of the body (11) further causes the gas to gradually push the fluid from the top to the bottom in the barrel (11) through the suction pipe (71) through the joint (72) to be led out of the container at the other end to achieve the forced action. And if the fluid is exported at a slow rate and the rate of gas filling into the barrel (11) is too fast and the pressure of the gas in the barrel (11) is too large, the pressure relief body (8) can be simultaneously pressurized. Influencing the upward extrusion, the gas can be temporarily discharged through the gap at the upper end of the pressure relief body (8), thereby achieving safety in use, and the pressure relief body (8) returns to normal pressure in the barrel (11) Can return To its original position for normal operator.
The liquid suction device of the invention has the advantage that since the suction device has to switch both the upper switching valve (2) and the lower switching valve (3) at the same time, the suctioning action of the device can be performed. Further, a safety procedure before use is formed, and in addition, since the flow of the fluid is carried out in the outer tub (1), it is also convenient to use.
In summary, it is understood that the present invention is novel, and the present invention is not found in any publication, and is in compliance with the provisions of Articles 21 and 22 of the Patent Law.
The above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto. That is, the equivalent changes and modifications made by the invention in accordance with the scope of the invention are still within the scope of the invention.
