具自動回中功能之閥芯結構Spool structure with automatic return function

本創作係涉及一種閥芯結構，特別是指一種具自動回中功能之創新結構型態揭示者。The present invention relates to a valve core structure, and more particularly to an innovative structural type revealer with an automatic return function.

按，可依使用者選擇而供應冷水或熱水之雙溫水龍頭，由於其使用方便且兼具調節出水溫度之功能，因此，長期以來一直是廚房與浴室不可或缺之給水設備。Pressed, the double-temperature faucet that can supply cold water or hot water according to the user's choice. Because of its convenient use and the function of adjusting the water temperature, it has long been an indispensable water supply equipment for kitchens and bathrooms.

而達到前述選擇出水溫度之最主要結構，便是雙溫水龍頭中所設置之陶瓷控水閥。習知雙溫水龍頭業者所一直沿用之陶瓷控水閥結構設計，當其位於中段位置時，若使用者在此位置開啟陶瓷控水閥，其供水的狀態是冷、熱水相混合狀態，此種使用狀態於雙溫水龍頭產品結構設計上雖已沿革許久，但吾人卻發現此種結構型態其實存在一些問題點；其原因在於，若要讓雙溫水龍頭於扳起把手時為供應冷水狀態，使用者當然可以透過先將把手擺轉至全冷水之出水位置，再扳起的正確操作方式來達成。假設使用者在不經意或不知情（如幼兒、老年人等）的情況下，於中間段位置向上扳起習知雙溫水龍頭把手，按理而言其所流出者應為冷、熱水平均混合的溫水狀態，但實際使用上卻存在不穩定因素，例如：此時若冷水端之水壓小於熱水端之水壓大時，實際上就會變成熱水模式，如此一來就有燙傷使用者的潛在危險。再者，使用者在中間段位置扳起把手時，由於冷、熱水入水孔道均僅局部開通，如此，對於熱水部份而言也可能因為水壓不足，而無法於熱水器中達到點燃瓦斯的標準，進而容易引發瓦斯漏氣的問題；即使瓦斯能夠順利點燃，若使用者僅是要洗手而已，當熱水尚未流出或才剛流出，使用者通常便已完成洗手動作，並關閉雙溫水龍頭，而將加溫後之熱水留存於管路中，這無疑是一種能源的浪費。The most important structure to achieve the aforementioned selection of the outlet water temperature is the ceramic water control valve provided in the double temperature faucet. The structure of the ceramic water control valve that has been used by the dual-temperature faucet industry has been designed. When the user is in the middle position, if the user opens the ceramic water control valve at this position, the water supply state is the mixed state of cold and hot water. Although the state of use has been in the design of the dual-temperature faucet product for a long time, we have found that there are some problems in this type of structure; the reason is that if the double-temperature faucet is to supply the cold water when the handle is pulled The user can of course achieve this by first turning the handle to the position of the outlet of the cold water and then pulling it up. Assume that the user raises the conventional double-temperature faucet handle in the middle position in the case of inadvertent or uninformed (such as children, the elderly, etc.), and it is reasonable that the outflow should be an average of cold and hot water. Warm water, but there are unstable factors in actual use. For example, if the water pressure at the cold water end is lower than the water pressure at the hot water end, it will actually become hot water mode, so there will be burns. The potential danger of the person. Moreover, when the user raises the handle at the middle position, since the cold and hot water inlet channels are only partially opened, the hot water portion may not be able to reach the ignition gas in the water heater due to insufficient water pressure. The standard is easy to cause gas leakage problems; even if the gas can be ignited smoothly, if the user only needs to wash his hands, when the hot water has not flowed out or just flowed out, the user usually has finished the hand washing action and closes the double temperature faucet. And retaining the heated hot water in the pipeline, this is undoubtedly a waste of energy.

為了避免前述之各項缺失，便有陶瓷閥業者將活動閥片上之水流控制槽往固定閥片之冷水導入口偏置，令陶瓷控水閥處於中段位置時，僅有冷水導入口得與水流控制槽連通。然而，不管活動閥片的結構設計得載完整，若是前一位使用者或是飯店房務人員，未確實將操控閥芯的扳桿移動到中段位置時，一切還是枉然。In order to avoid the above-mentioned defects, the ceramic valve manufacturer biases the water flow control groove on the movable valve plate to the cold water inlet of the fixed valve plate, so that when the ceramic water control valve is in the middle position, only the cold water inlet and the water flow are obtained. The control slots are connected. However, regardless of the structural design of the active valve plate, if the former user or the hotel room staff did not actually move the trigger of the valve spool to the middle position, everything is still vain.

是以，針對上述習知結構所存在之問題點，如何開發一種更具理想實用性之閥芯創新結構，實使用者所企盼，亦係相關業者須努力研發突破之目標及方向。Therefore, in view of the problems existing in the above-mentioned conventional structure, how to develop a valve core innovation structure that is more ideal and practical, is expected by users, and is also related to the industry's efforts to develop breakthrough goals and directions.

The second end 342 of the resetting element 34 abuts the second abutting end 215 and the second limiting end 332, respectively.

藉由上述結構組成設計，茲就本創作之使用作動情形說明如下：如第6A至6C圖所示，當使用者利用扳桿組20旋動活動閥片50而欲提高出水溫度時，如第6B、6C圖中箭頭方向所示，該驅動板213之第一頂抵端214會頂抵復位元件34之第一卡制端341，並於旋轉座21相對於殼體10旋轉時，利用安裝座30無法相對於殼體10旋轉，以及復位元件34之第二卡制端342受限於安裝結構33之第二限位端332之特性，開始驅動復位元件34蓄積復位能。此時閥芯結構仍持續出水，由於水壓之持續作用令活動閥片50與固定閥片70間之摩擦力相對較大，因此，復位元件34所蓄積之復位能尚無法反推旋轉座21；當扳桿組20復位並關閉活動閥片50與固定閥片70間之流道後，因作用於活動閥片50與固定閥片70間之水壓瞬間消失，導致活動閥片50與固定閥片70間之摩擦力相對變小，令復位元件34得以利用其所蓄積之復位能，透過驅動板213反推扳桿組20復位並連動活動閥片50令其自動回復到中段位置，以克服前述習用閥芯結構之缺失。又如第7A至7C圖所示，其中所示之操作方式與前述操作方式僅作動方向相反，而提供自動復位之功能完全相同，因此不再贅述。With the above structural composition design, the operation of the present invention is explained as follows: as shown in FIGS. 6A to 6C, when the user uses the trigger set 20 to rotate the movable valve piece 50 to increase the water temperature, as in the first The first abutting end 214 of the driving plate 213 abuts against the first locking end 341 of the restoring member 34, and is mounted when the rotating base 21 is rotated relative to the housing 10, as indicated by the direction of the arrow in FIGS. 6B and 6C. The seat 30 is incapable of rotating relative to the housing 10, and the second carded end 342 of the reset member 34 is limited by the characteristics of the second limit end 332 of the mounting structure 33, and begins to drive the reset element 34 to accumulate reset energy. At this time, the valve core structure continues to discharge water, and the friction between the movable valve piece 50 and the fixed valve piece 70 is relatively large due to the continuous action of the water pressure. Therefore, the resetting energy accumulated by the resetting element 34 cannot reverse the rotating seat 21 When the trigger set 20 is reset and the flow path between the movable valve piece 50 and the fixed valve piece 70 is closed, the water pressure between the movable valve piece 50 and the fixed valve piece 70 disappears instantaneously, resulting in the movable valve piece 50 and the fixed valve. The friction between the sheets 70 is relatively small, so that the resetting element 34 can use the resetting energy accumulated therein to reversely push the trigger lever group 20 through the driving plate 213 to reset and interlock the movable valve plate 50 to automatically return to the middle position to overcome The aforementioned conventional valve core structure is missing. Further, as shown in Figs. 7A to 7C, the operation mode shown therein is opposite to the operation mode of the foregoing operation mode, and the functions of providing automatic reset are completely the same, and therefore will not be described again.
