Description

濾油器及用於濾油器的蓋體Oil filter and cover for oil filter

本發明係與汽車用的濾油器有關；特別是指一種便於拆裝且能夠避免拆裝過程滴油的濾油器及用於濾油器的蓋體。The invention relates to an oil filter for automobiles; in particular, it refers to an oil filter and a cover body for the oil filter which is convenient for disassembly and assembly and can avoid oil dripping during disassembly and assembly.

為了讓汽車引擎順暢地運轉，會加入機油至該引擎的各個零件當中，以增加潤滑效果。機油在潤滑機械的同時也容易帶走零件上的雜質，因此汽車會加裝一濾油器，用以過濾機油中的雜質，使汽車引擎保持正常運作。In order to make the car engine run smoothly, oil is added to various parts of the engine to increase the lubrication effect. While lubricating machinery, oil is also easy to take away impurities on parts, so the car will be equipped with an oil filter to filter impurities in the oil and keep the car engine running normally.

已知濾油器通常設置於汽車引擎處之一容置部位，該容置部位具有一入油口與一出油口，其中該容置部位的入油口對應該濾油器的導入口，該容置部位的出油口對應該濾油器的導出口，機油經該出油口輸出該容置部位並經該導入口進入該濾油器內，經過濾油器內的濾芯進行過濾後，濾清後的機油自該導出口離開該濾油器，並自該入油口再次進入該容置部位中，以供汽車引擎使用。A known oil filter is usually installed at an accommodating part of an automobile engine, and the accommodating part has an oil inlet and an oil outlet, wherein the oil inlet of the accommodating part corresponds to the inlet of the oil filter, The oil outlet of the accommodating part corresponds to the outlet of the oil filter. The oil is output from the accommodating part through the oil outlet and enters the oil filter through the inlet port. After being filtered by the filter element in the oil filter , the filtered oil leaves the oil filter from the lead-out port, and enters the accommodating part again from the oil inlet port to be used by the automobile engine.

然，習知過濾器內的濾芯需要被替換時，需要將濾油器自該容置部位上拆下，而許多汽車引擎的該容置部位多設置於後座坐墊底下，導致於拆卸過程常常將過濾器內殘留的機油滴染於坐墊或是後座的腳踏毯上；此外，習知在替換濾芯的過程中，需要以手去抓取濾芯才能自該容置部位中或是該濾油器中移出，容易弄髒使用者雙手，造成不便。However, when the filter element in the conventional filter needs to be replaced, the oil filter needs to be removed from the accommodating part, and the accommodating part of many automobile engines is mostly arranged under the rear seat cushion, resulting in the frequent disassembly process. Dye the oil remaining in the filter on the seat cushion or the back seat carpet; in addition, it is known that in the process of replacing the filter element, it is necessary to grab the filter element by hand to remove the filter element from the accommodating part or the filter element. If it is removed from the oiler, it is easy to soil the hands of the user and cause inconvenience.

除此之外，對於一些習知過濾器而言，其過濾器的外殼與位於外殼內的濾芯為一體成型的結構，如此一來，當過濾器的濾芯需要被替換時，要將整個過濾器丟棄，上述情況不僅造成資源上的浪費，還相當不環保。是以，上述問題時有解決之必要。In addition, for some conventional filters, the housing of the filter and the filter element located in the housing are integrally formed. In this way, when the filter element of the filter needs to be replaced, the entire filter element needs to be replaced.

藉由上述結構設計，於下說明該濾油器100濾清該汽車之機油的方法。如圖7A與8所示，機油自該容置部位200第二開口200b流入該濾油器100中。機油於經第二導口O2後進入該第二腔室S2當中，並再於經該第一通道A1但不經該第二通道A2，且受該過濾筒體34過濾掉機油中的雜質後，進入該第一腔室S1中。於該第一腔室S1中的機油自該第一導口O1流出濾油器100，並於經該第一開口200a後，回到該汽車的引擎中。此外，在機油進入第一腔室S1時，該芯柱326可對機油產生擾流作用，可增加該過濾筒體34與機油的接觸時間，藉以提升濾淨效果。With the above-mentioned structural design, the method for filtering the oil of the automobile by the oil filter 100 is described below. As shown in FIGS. 7A and 8 , the oil flows into the oil filter 100 from the second opening 200 b of the accommodating portion 200 . The oil enters the second chamber S2 after passing through the second guide port O2, and then passes through the first channel A1 but not the second channel A2, and is filtered by the filter cylinder 34 to remove impurities in the oil , into the first chamber S1. The oil in the first chamber S1 flows out of the oil filter 100 from the first guide port O1, and returns to the engine of the automobile after passing through the first opening 200a. In addition, when the oil enters the first chamber S1, the stem 326 can disturb the flow of the oil, which can increase the contact time between the filter cylinder 34 and the oil, thereby improving the filtering effect.

補充說明的是，圖8所示之機油於第二腔室S2中係朝穿出紙面的方向X流動，機油於第一腔室S1係朝進入紙面的方向O流動。It is supplemented that the oil shown in FIG. 8 flows in the direction X passing through the paper surface in the second chamber S2 , and the oil flows in the direction O entering the paper surface in the first chamber S1 .

長期使用下來，該過濾筒體34的濾紙上之孔洞會受機油中的雜質慢慢阻塞，使得機油漸漸無法自該第二腔室S2於經該第一通道A1通過後流入該第一腔室S1當中。為了保持該汽車引擎可以順暢地運作，如圖9所示，機油會朝該第二通道A2的方向流動，並且給予該移動件364一外部壓力（未繪示）。當該外部壓力大於或等於一預定壓力（未繪示）時，該液壓開關36會自該關閉狀態轉為該開啟狀態，於第二腔室S2內的機油於經該第二通道A2後，流至該第一腔室S1中。然，於此同時，於該第二腔室S2中的部分機油可自該第一通道A1流至該第一腔室S1，亦可為，於該第二腔室S2中的機油皆自該第二通道A2流至該第一腔室S1。After long-term use, the holes on the filter paper of the filter cylinder 34 will be slowly blocked by impurities in the oil, so that the oil gradually cannot flow into the first chamber from the second chamber S2 after passing through the first channel A1 Among S1. In order to keep the automobile engine running smoothly, as shown in FIG. 9 , the oil will flow in the direction of the second passage A2 and give an external pressure (not shown) to the moving member 364 . When the external pressure is greater than or equal to a predetermined pressure (not shown), the hydraulic switch 36 will turn from the closed state to the open state, and the oil in the second chamber S2 passes through the second passage A2, into the first chamber S1. However, at the same time, part of the oil in the second chamber S2 may flow from the first channel A1 to the first chamber S1, or the oil in the second chamber S2 may all flow from the The second channel A2 flows to the first chamber S1.

請參圖10至圖12所示為本發明第二較佳實施例之濾油器300。該濾油器300中之液壓開關36A同樣具有一固定件362A、一移動件364A及一彈性件366A，該濾油器300的液壓開關36A與第一較佳實施例之濾油器100的液壓開關36差異在於，該移動件364A係抵接於該固定件362A靠近該蓋體20A之一側的端緣，意即該移動件364A的至少一部位位於該中心筒體32A外。該彈性件366A則位於該中心筒體32A中，且該彈性件366A的一端緣卡設於該移動件364A的頭部與該移動件364A的一凸部365A之間，另一端緣則卡抵於該芯柱326A的一凸部327A，進而使該彈性件366A的兩端緣保持連接該移動件364A與該芯柱326A。Please refer to FIG. 10 to FIG. 12 , which show an oil filter 300 according to a second preferred embodiment of the present invention. The hydraulic switch 36A of the oil filter 300 also has a fixed part 362A, a moving part 364A and an elastic part 366A. The hydraulic switch 36A of the oil filter 300 is the same as the hydraulic pressure of the oil filter 100 of the first preferred embodiment. The difference of the switch 36 is that the moving member 364A abuts on the edge of the fixing member 362A close to one side of the cover 20A, which means that at least a part of the moving member 364A is located outside the central cylinder 32A. The elastic member 366A is located in the central cylinder 32A, one end edge of the elastic member 366A is clamped between the head of the moving member 364A and a convex portion 365A of the moving member 364A, and the other end edge is clamped against A protruding portion 327A of the core column 326A keeps both ends of the elastic member 366A connected to the moving member 364A and the core column 326A.

該濾油器300所應用的汽車引擎的容置部位400與該濾油器100所應用的汽車引擎的容置部位200差異在於，該容置部位400的第一開口400a為汽車引擎的出油口，第二開口400b為汽車引擎的入油口。因此，當該液壓開關36於該關閉狀態時，機油係自該第一開口400a進入該濾油器300中，而後，機油於經第一導口O1後進入該第一腔室S1當中，並再於經該第一通道A1且受該過濾筒體34A過濾掉機油中的雜質，再進入該第二腔室S2中。而後，於該第二腔室S2中之機油從該第二導口O2離開該濾油器300，並於經該第二開口400b後，回到該汽車的引擎中。The difference between the accommodating part 400 of the car engine applied by the oil filter 300 and the accommodating part 200 of the car engine applied by the oil filter 100 is that the first opening 400a of the accommodating part 400 is the oil outlet of the car engine The second opening 400b is the oil inlet of the automobile engine. Therefore, when the hydraulic switch 36 is in the closed state, the oil enters the oil filter 300 from the first opening 400a, and then the oil enters the first chamber S1 through the first guide port O1, and After passing through the first channel A1 and being filtered by the filter cylinder 34A, the impurities in the oil are filtered out, and then enter the second chamber S2. Then, the oil in the second chamber S2 leaves the oil filter 300 from the second guide port O2, and returns to the engine of the automobile after passing through the second opening 400b.

補充說明的是，圖11所示之機油於第二腔室S2中係朝進入紙面的方向X流動，機油於第一腔室S1係朝穿出紙面的方向O流動。It is supplemented that the oil shown in FIG. 11 flows in the direction X entering the paper in the second chamber S2, and the oil flows in the direction O passing out of the paper in the first chamber S1.

相同於第一實施例中之移動件364，如圖12所示，當該移動件364A受一大於或等於一預定壓力的外部壓力時，會導致該液壓開關36A於該開啟狀態，該第二通道A2被開啟。此時，本實施例中之移動件364A不接觸該固定件362A且該彈性件366A被拉伸，機油則能自該第一腔室S1，於經該第二通道A2後，流至該第二腔室S2中。Similar to the moving member 364 in the first embodiment, as shown in FIG. 12 , when the moving member 364A is subjected to an external pressure greater than or equal to a predetermined pressure, the hydraulic switch 36A will be in the open state, and the second Channel A2 is turned on. At this time, the moving member 364A in this embodiment does not contact the fixing member 362A and the elastic member 366A is stretched, and the oil can flow from the first chamber S1 to the second passage A2 after passing through the second passage A2. in the second chamber S2.

值得一提的是，一些汽車的容置部位上已設置有一濾心組件，且該濾心組件具有相同於第一較佳實施例中之凹部。在這種情況下，可應用第一或第二較佳實施例中之殼體及蓋體的結構，將該殼體罩設於該濾心組件外，且該殼體不具有該放置口之一端連接於該汽車的容置部位。而該蓋體的外螺紋段與該殼體的內螺紋段結合，該蓋體的凸部卡設於該濾心組件的凹部，使得該蓋體以可拆離的方式結合於該濾心組件。另於其他實際應用上濾心組件可具有凸部，蓋體可具有凹部。It is worth mentioning that a filter element is already installed on the accommodating part of some automobiles, and the filter element has the same concave part as that in the first preferred embodiment. In this case, the structure of the casing and the cover in the first or second preferred embodiment can be applied, the casing is placed outside the filter element, and the casing does not have the placement opening. One end is connected to the accommodating part of the automobile. The outer threaded section of the cover is combined with the inner threaded section of the housing, and the convex part of the cover is clamped to the concave part of the filter element, so that the cover is detachably combined with the filter element . In other practical applications, the filter element may have a convex portion, and the cover body may have a concave portion.

The cover body 20B has an external thread segment 22B, the housing 602 has an internal thread segment 604, and the external thread segment 22B is locked to the internal thread segment 604, so that the cover body 20B is detachable from the housing Body 602 binds. The method of filtering the oil in this embodiment is the same as the method of filtering the oil in the first embodiment, which will not be described.

補充說明的是，該容置部位600設置有一定位部606，該定位部606係用以供該濾心組件30B的過濾筒體34A卡合定位，增加整體濾心組件30B的穩定性。It is added that the accommodating portion 600 is provided with a positioning portion 606, and the positioning portion 606 is used for engaging and positioning the filter cylinder 34A of the filter element 30B to increase the stability of the overall filter element 30B.

於其他實際應用上，第三實施例之過濾器500中所採用的濾心組件，除了可同於第一實施例中之濾心組件30的設計之外，亦可同於第二實施例中之濾心組件30B的設計。此外，上述第一實施例至第三實施例中之蓋體與中心筒體亦可為一體成型者，而非以可拆離的方式彼此結合。再者，上述有關可拆離式的結合關係並不限於內外螺紋段之配合，或是凸凹部之配合。In other practical applications, the filter element used in the filter 500 of the third embodiment can also be the same as the design of the filter element 30 in the second embodiment except for the design of the filter element 30 in the first embodiment. The design of the filter element 30B. In addition, the cover body and the central cylinder body in the above-mentioned first to third embodiments can also be integrally formed instead of being detachably combined with each other. Furthermore, the above-mentioned detachable coupling relationship is not limited to the cooperation of the inner and outer thread segments, or the cooperation of the convex and concave portions.

值得一提的是，一些汽車的容置部位上已設置有一濾油器，換言之，該汽車的容置部位上設置有相當於第一至第三較佳實施例之任一者中所述之殼體與濾心組件。在這種情況下，可應用本發明之用於濾油器的蓋體，將該蓋體的外螺紋段與該殼體的內螺紋段連接，使得該蓋體以可拆離的方式結合於該殼體，且該蓋體的凸部與該濾心組件的凹部結合，使得該蓋體以可拆離的方式結合於該濾心組件。另於其他實際應用上，本發明之殼體可具有外螺紋段，蓋體可具有內螺紋段；蓋體可具有凹部，濾心組件可具有凸部。It is worth mentioning that an oil filter is already installed on the accommodating part of some automobiles.
