Description
技术领域technical field
本实用新型是关于一种空气滤清器构造，尤指一种具有油气过滤部的空气滤清器构造。The utility model relates to an air filter structure, in particular to an air filter structure with an oil and gas filtering part.
背景技术Background technique
摩托车为一种由引擎或马达驱动，利用手把操纵方向的二轮或三轮车辆，由于有着操纵简单、行动方便及价格低廉的特点，成为目前最常利用的交通工具。A motorcycle is a two-wheeled or three-wheeled vehicle driven by an engine or a motor and controlled by a handlebar. Due to its simple operation, convenient movement and low price, it has become the most commonly used means of transportation.
在现有摩托车结构设计中，会配置油气分离机构来过滤从引擎的吹漏气管排放的油气混合气体，确保将引擎的曲轴箱的机油油气回吸至引擎再利用时，使吸入进气岐管的油气混合气体中的油气含量再次减低，避免引擎发生积碳及作动不良等现象。In the structural design of the existing motorcycle, an oil and gas separation mechanism is configured to filter the oil and gas mixture discharged from the blow-by air pipe of the engine, so as to ensure that the oil and gas in the crankcase of the engine are sucked back into the engine for reuse, so that the intake air can be sucked into the air. The oil and gas content in the oil-air mixture of the manifold is reduced again, preventing the occurrence of carbon deposits and poor operation of the engine.
一般来说，油气分离机构可区分为外挂式及内置式两种，其中，内置式主要在空气滤清器内部区隔一油气分离空间，使油气在油气分离空间内再次分离及凝结，而分离后的凝结液态油及凝结水气则是通过集油管收集后，于维修时清理，然而，由于常规油气分离空间易受到引擎进气时的负压变化所影响，导致机油油气容易大量地被从引擎被吸出，造成机油吐出量过多而影响机油油气的再利用燃烧。Generally speaking, the oil and gas separation mechanism can be divided into two types: plug-in type and built-in type. Among them, the built-in type mainly separates an oil and gas separation space inside the air filter, so that the oil and gas can be separated and condensed again in the oil and gas separation space. The condensed liquid oil and condensed water vapor are collected through the oil collecting pipe and cleaned up during maintenance. However, because the conventional oil and gas separation space is easily affected by the negative pressure change during the intake of the engine, the oil and gas are easily removed from the engine in large quantities. The engine is sucked out, resulting in too much oil spit out and affecting the reuse and combustion of oil and gas.
为了改善上述问题，本创作人思及一种空气滤清器构造，利用空气滤清器构造内所形成的空气清净室，使其连通由第一油气过滤构件与第二油气过滤构件所共同形成的腔室，可有效减少引擎负压对于引擎机油吐出量的影响，确保机油油气回收燃烧的过程中，不会有过量油气被吸出，进而改善引擎零件的运动效能，创作人缘因于此，本于积极创作的精神，亟思一种具有上述功能的空气滤清器构造，几经研究实验终至完成本实用新型。In order to improve the above problems, the author of the present invention has thought of an air filter structure, which uses the air clean room formed in the air filter structure to communicate with the first oil and gas filter member and the second oil and gas filter member. The chamber can effectively reduce the impact of engine negative pressure on the output of engine oil, and ensure that during the process of oil and gas recovery and combustion, no excess oil and gas will be sucked out, thereby improving the movement performance of engine parts. In the spirit of active creation, an air filter structure with the above functions was urgently thought, and the present utility model was finally completed after several researches and experiments.

The partition plate 12 is arranged on the box body 11, and together with the box body 11 forms an air cleaning chamber C which is communicated with the air outlet. The partition plate 12 has a mounting hole 121. , the oil and gas filter part 13 is located between the box body 11 and the partition plate 12, and forms a chamber with an inner oil and gas channel P1 and an outer oil and gas channel P2 that communicate with each other. The oil and gas filter part 13 includes an oil and gas inlet A, a A first opening A1, a second opening A2, a third opening A3 and a fourth opening A4, the inner oil and gas passage P1 communicates with the blow-by air pipe of the engine of the motorcycle through the oil and gas inlet A, and the outer oil and gas passage P2 passes through The first opening A1 and the second opening A2 communicate with the air cleaning chamber C, and the cross-sectional area of the first opening A1 is larger than the cross-sectional area of the second opening A2. Therefore, when the air cleaning chamber C becomes a negative pressure state, it is located in the oil and gas filter. The gas in the chamber formed by the part 13 will flow toward the first opening A1 with less air resistance.
详细而言，油气过滤部13的内油气通道P1及外油气通道P2的腔室是由一第一油气过滤构件131及一第二油气过滤构件132所形成，第一油气过滤构件131与箱体11为一体成形的结构，第二油气过滤构件132与隔板12为一体成形的结构，箱体11上的第一油气过滤构件131及隔板12上的第二油气过滤构件132共同形成具有相互连通的内油气通道P1及外油气通道P2的油气过滤部13，第二油气过滤构件132具有连通内油气通道P1及外油气通道P2的第三开口A3，其位于内油气通道P1的上侧，且第二油气过滤构件132具有连通内油气通道P1及外油气通道P2的第四开口A4，其位于内油气通道P1的下侧。In detail, the chambers of the inner oil and gas passage P1 and the outer oil and gas passage P2 of the oil and gas filtering portion 13 are formed by a first oil and gas filtering member 131 and a second oil and gas filtering member 132 . The first oil and gas filtering member 131 is connected to the casing. 11 is an integrally formed structure, the second oil and gas filter member 132 is an integrally formed structure with the partition plate 12, the first oil and gas filter member 131 on the box body 11 and the second oil and gas filter member 132 on the partition plate 12 together form a mutual The oil and gas filter part 13 of the inner oil and gas passage P1 and the outer oil and gas passage P2 that are communicated, the second oil and gas filtering member 132 has a third opening A3 that communicates with the inner oil and gas passage P1 and the outer oil and gas passage P2, and is located on the upper side of the inner oil and gas passage P1, And the second oil and gas filter member 132 has a fourth opening A4 that communicates with the inner oil and gas passage P1 and the outer oil and gas passage P2, which is located on the lower side of the inner oil and gas passage P1.
承上，第一开口A1位于远离滤芯构件14的一侧，第三开口A3位于远离第一开口A1的一侧，第四开口A4位于邻近集油口111的一侧，因此，使第一油气过滤构件131及第二油气过滤构件132共同形成的腔室，能够利用由内层结构所包围形成的内油气通道P1，以及内层结构及外层结构所包围形成的外油气通道P2来进行油气过滤，可以避免机油油气大量地被从引擎被吸出，有效地将油气混合气体进行过滤并分离。On the other hand, the first opening A1 is located on the side away from the filter element 14, the third opening A3 is located on the side away from the first opening A1, and the fourth opening A4 is located on the side adjacent to the oil collecting port 111. The chamber formed by the filter member 131 and the second oil and gas filter member 132 can utilize the inner oil and gas channel P1 surrounded by the inner layer structure and the outer oil and gas channel P2 surrounded by the inner layer structure and the outer layer structure to carry out oil and gas. Filtration can prevent a large amount of oil and oil from being sucked out of the engine, and effectively filter and separate the oil-air mixture.
滤芯构件14设置于安装孔121上，壳体15设置于箱体11上，并具有一依序连通滤芯构件14及空气清净室C之入气口，且隔板12及滤芯构件14位于箱体11及壳体15之间，过滤材料16设置于第一油气过滤构件131及第二油气过滤构件132之间，并位于内油气通道P1内，因此，滤芯构件14过滤从外部环境所吸入的空气，使空气清净室C内的气体不会残留外部环境带来的异物等杂质，而过滤材料16过滤油气进气口A所导入的油气混合气体，使空气清净室C内的气体油气含量降低，因而改善引擎的运转效能。The filter element 14 is arranged on the mounting hole 121 , the casing 15 is arranged on the box body 11 , and has an air inlet connecting the filter element 14 and the air cleaning chamber C in sequence, and the partition plate 12 and the filter element 14 are located in the box body 11 and the housing 15, the filter material 16 is arranged between the first oil and gas filtering member 131 and the second oil and gas filtering member 132, and is located in the inner oil and gas passage P1, therefore, the filter element 14 filters the air sucked in from the external environment, So that the gas in the air cleaning room C will not leave impurities such as foreign objects brought by the external environment, and the filter material 16 filters the oil and gas mixture introduced by the oil and gas inlet A, so that the gas oil and gas content in the air cleaning room C is reduced, so Improve engine performance.
出气管17设置于出气口上，并与摩托车引擎的进气岐管连通，入气管18设置于入气口上，可导入外部环境之空气依序流动至滤芯构件14及空气清净室C，集油管19设置于集油口111上，用以收集第一油气过滤构件131及第二油气过滤构件132的过滤残留物。The air outlet pipe 17 is arranged on the air outlet and communicated with the intake manifold of the motorcycle engine. The air inlet pipe 18 is arranged on the air inlet port, and the air that can be introduced into the external environment flows to the filter element 14 and the air cleaning chamber C in sequence, and collects the air. The oil pipe 19 is disposed on the oil collecting port 111 for collecting the filtering residues of the first oil and gas filtering member 131 and the second oil and gas filtering member 132 .
接下来，参阅图5，其为本实用新型的空气滤清器构造的油气混合气体流动方向示意图，同时配合参阅图1至图4进行说明。Next, refer to FIG. 5 , which is a schematic diagram of the flow direction of the oil-air mixture of the air filter structure of the present invention, and is also described with reference to FIGS. 1 to 4 .
首先，在摩托车的引擎运转时，从引擎的吹漏气管所排出的油气混合气体会被引导流动至第一油气过滤构件131的油气进气口A处，由第一油气过滤构件131之内油气通道P1处，经过过滤材料16进行过滤后，到达第二油气过滤构件132的内油气通道P1处，此时，油气混合气体已分离成油气及凝结液态油，气体状态的油气会经由第二油气过滤构件132的第三开口A3流动至外油气通道P2，而液体状态的凝结液态油则是经由第二油气过滤构件132的第四开口A4流动至外油气通道P2。First of all, when the engine of the motorcycle is running, the oil-air mixture discharged from the blow-by air pipe of the engine will be guided to flow to the air-air inlet A of the first oil-air filter member 131, and the air-air mixture will be discharged by the first oil-air filter member 131. At the inner oil and gas channel P1, after being filtered by the filter material 16, it reaches the inner oil and gas channel P1 of the second oil and gas filter member 132. At this time, the oil and gas mixture has been separated into oil and gas and condensed liquid oil, and the gas in the gas state will pass through the first oil and gas. The third opening A3 of the second oil and gas filtering member 132 flows to the outer oil and gas passage P2, and the condensed liquid oil in liquid state flows to the outer oil and gas passage P2 through the fourth opening A4 of the second oil and gas filtering member 132.
承上，在摩托车的引擎运转的同时，引擎的进气岐管透过出气管17会将空气清净室C内的气体吸入至引擎的燃烧室使用，因而使空气清净室C持续处于负压状态，空气清净室C的负压状态会促使从入气管18导入的外部空气流动至空气清净室C内。On the other hand, while the engine of the motorcycle is running, the intake manifold of the engine will suck the gas in the clean air chamber C into the combustion chamber of the engine through the air outlet pipe 17, so that the clean air chamber C is continuously under negative pressure. state, the negative pressure state of the clean air chamber C causes the outside air introduced from the air intake pipe 18 to flow into the clean air chamber C.
此时，由于第一油气过滤构件131及第二油气过滤构件132共同形成的腔室的第一开口A1的截面积大于第二开口A2的截面积，因此过滤后的油气及凝结液态油会因空气清净室C的负压朝向空气阻力小的第一开口A1侧流动，同时，在外油气通道P2内，经由第一开口A1被空气清净室C的负压所带走的气体会促使第二开口A2处吸入空气清净室C内的气体。At this time, since the cross-sectional area of the first opening A1 of the chamber formed by the first oil and gas filtering member 131 and the second oil and gas filtering member 132 is larger than the cross-sectional area of the second opening A2, the filtered oil and gas and condensed liquid oil will be The negative pressure of the air cleaning room C flows toward the side of the first opening A1 with the small air resistance, and at the same time, in the outer oil and gas passage P2, the gas taken away by the negative pressure of the air cleaning room C through the first opening A1 will promote the second opening. At A2, the gas in the air cleaning room C is sucked.
而因空气清净室C的负压所产生的气体流动现象，不但促使邻近第四开口A4处的凝结液态油流动至集油口111处，也促使空气清净室C内所产生的冷凝水或未被滤芯构件14成功过滤的沙粒等杂质，会经由第二开口A2流动进入外油气通道P2的下侧，并朝向集油口111处流动，再以设置于集油口111上的集油管19将凝结液态油、冷凝水及沙粒等杂质收集处理，因而提升引擎运转时所使用的燃烧气体品质，进而改善引擎的运转效能。The gas flow phenomenon caused by the negative pressure in the air cleaning chamber C not only promotes the condensed liquid oil near the fourth opening A4 to flow to the oil collecting port 111, but also promotes the condensed water or untreated water generated in the air cleaning chamber C to flow to the oil collecting port 111. The impurities such as sand particles successfully filtered by the filter element 14 will flow into the lower side of the outer oil and gas passage P2 through the second opening A2, and flow toward the oil collecting port 111, and then the oil collecting pipe 19 provided on the oil collecting port 111 will flow. It collects and treats impurities such as condensed liquid oil, condensed water and sand particles, thereby improving the quality of combustion gas used in engine operation, thereby improving the operating efficiency of the engine.
另外，在本实用新型中虽以第一油气过滤构件131及一第二油气过滤构件132来构成油气过滤部13，使其具有相互连通的内油气通道P1及外油气通道P2的结构来稳定地进行过滤，但并不仅限于此，也可将油气过滤部13以单一构件形成，也就是说，使单一构件的油气过滤部13具有油气进气口A、第一开口A1、第二开口A2、第三开口A3、第四开口A4、内油气通道P1及外油气通道P2的结构，并设置于箱体11及隔板12之间，同样地可以产生相同的气体流动现象，并发挥相同的过滤效果。In addition, in the present invention, although the first oil and gas filter member 131 and a second oil and gas filter member 132 are used to form the oil and gas filter portion 13, it has the structure of the inner oil and gas passage P1 and the outer oil and gas passage P2 that are connected to each other to stably For filtering, but not limited to this, the oil and gas filtering part 13 can also be formed by a single component, that is, the oil and gas filtering part 13 of a single component has the oil and gas inlet A, the first opening A1, the second opening A2, The structure of the third opening A3, the fourth opening A4, the inner oil and gas passage P1 and the outer oil and gas passage P2 are arranged between the box body 11 and the partition plate 12, which can also produce the same gas flow phenomenon and exert the same filtering effect. Effect.
由上述内容可知，本实用新型在第一油气过滤构件131及第二油气过滤构件132共同形成的腔室内，形成内外双层的内油气通道P1及外油气通道P2，内油气通道P1再次过滤从引擎的吹漏气管所排出的油气混合气体，外油气通道P2则是作为缓冲区域，可以使油气混合气体在内油气通道P1中稳定地受到过滤，不被空气清净室C的负压所影响而吸出过多油气混合气体，有效地再次分离吹漏气管所排出的油气混合气体，进而提升用于引擎的燃烧气体品质，并改善引擎零件之作动效能。It can be seen from the above content that the present invention forms an inner and outer double-layered inner oil and gas passage P1 and an outer oil and gas passage P2 in the chamber jointly formed by the first oil and gas filtering member 131 and the second oil and gas filtering member 132, and the inner oil and gas passage P1 is filtered again from The oil and gas mixture discharged from the blow-by air pipe of the engine, the outer oil and gas channel P2 is used as a buffer area, so that the oil and gas mixture can be stably filtered in the inner oil and gas channel P1, and is not affected by the negative pressure of the air cleaning room C. Excessive oil-air mixture is sucked out, and the oil-air mixture discharged from the blow-by air pipe is effectively separated again, thereby improving the quality of combustion gas used in the engine and improving the operating performance of engine parts.
