Description

过滤结构 技术领域
本发明是有关于一种过滤结构，尤指一种具有良好的透气度与过滤效果的过滤结构。
背景技术
过滤结构一直是民众常常会使用到的日常用品之一，例如口罩，现今空气污染越来越严重，不管是工业废气或汽机车所排放的废气等等，其皆对环境造成极大的影响，且对于人的身体健康也影响相当大，所以对骑乘机车的机车骑士而言，口罩是不可或缺的必需品。另外，对于医疗方面而言，医疗口罩也是不可或缺，例如好几年前有流行过SARS与禽流感的流行性传染病毒，因为此种病毒会造成死亡，所以当时口罩是供不应求。
现在的口罩的种类繁多，有纸口罩、外科口罩、N95口罩与活性碳口罩等等，各式各样的口罩基本上都具有防尘与过滤脏空气的基本功能。口罩是为了人们的健康而设计，其用于阻止对人体有害的可见或不可见物质进入人体。
一般口罩的阻尘效率是以对微细粉尘的阻隔效率为标准。因为直径小的粉尘能直接进入肺泡，对人体健康造成的影响最大。一般的防尘口罩，其阻尘方式是机械式过滤，就是当粉尘冲撞到口罩时，经过一层层纱布的阻隔，大颗粒粉尘就会被阻隔在纱布中。但是，一些微细粉尘就会从纱布的缝隙中穿过去，进入呼吸系统。现今有部分防尘口罩，其滤材由具有静电的纤维组成，微细粉尘在穿过此种滤材的过程中，其会被静电吸引而吸附在滤材，如此即可以有效阻隔微细粉尘，真正达到阻尘作用。
一般而言，良好的口罩应具备下列几种条件：一口罩与使用者的面部密合良好、二过滤效果佳、三呼吸阻力小与配戴舒适佳等等。口罩的过滤材料分为很多种包括普通织物、动物毛与无纺布等。
就现有习知技术而言，口罩的滤材一般都是织物，这种滤材要达到高的阻尘效率，唯一的方法就是增加厚度与密度，而增加厚度与密度的负面作用就是会提高呼吸阻力，所以透气度低，如此使用者配戴口罩时会呼吸不顺，而感到不舒适。
故，本发明针对以上现有习知技术的缺点做进一步的改良，本发明提出一种过滤结构，其主要利用具有多个皱褶的皱褶层增加过滤结构的过滤面积及透气度，有效改善以上现有习知技术的缺点，且本发明的过滤结构具有避免所述皱褶变形的设计，而避免透气度降低，因此其为一种具有新 颖性及进步性的发明。

实现发明的最佳方式
为更进一步阐述本发明为达成预定发明目的所采取的技术手段及功效，以下结合附图及较佳实施例，对依据本发明提出的过滤结构其具体实施方式、结构、特征及其功效，详细说明如后。
请参阅图1，其为本发明的第一实施例的过滤结构的示意图；如图所示，本实施例提供一种过滤结构1，过滤结构1包含面罩本体10与皱褶层20，皱褶层20具有多个皱褶210，并设置于面罩本体10，其中面罩本体10呈立体状，而皱褶层20同样也呈立体状，如图1所示，本实施例的面罩本体10及皱褶层20均呈杯状，所以本实施例的皱褶层20的几何形状(杯状)对应面罩本体10的几何形状(杯状)，然本实施例的面罩本体10及皱褶层20在未组装之前，两者即呈立体状。
本实施例的过滤结构1的皱褶层20因具有所述皱褶210，所以皱褶层20的表面积大于面罩本体10的表面积，而降低过滤结构1的内侧与过滤结构1的外侧间的压力差，如此过滤结构1具有高透气度，以避免用户配戴过滤结构1时发生闷热与呼吸困难等不舒服现象，而提高用户配戴过滤结构1时的舒适度。然后因皱褶层20的表面积大于面罩本体10的表面积，所以也增加过滤结构1的过滤面积，进而提升过滤结构1的过滤效果。
本实施例的面罩本体10包含呈杯状的第一定型层110。然本实施例的皱褶层20设置于第一定型层110的内侧，第一定型层110固定皱褶层20的几何形状，使皱褶层20维持呈立体状。因皱褶层20用于过滤从过滤结构1的外侧进入其内侧的空气，所以其材质可为任何种类的滤材。由于皱褶层20的材 质为滤材，其强度较为不足，所以皱褶层20容易因受外力而产生变形。然本实施例的皱褶层20通过第一定型层110支撑与保护，而皱褶层20可避免因受外力而产生变形。
本实施例的面罩本体10的第一定型层110的周缘已具有第一结合部130，而皱褶层20的周缘已具有定型部250，其中定型部250固定皱褶层20的所述皱褶210，即定型部250用于定型所述皱褶210，以有效避免所述皱褶210产生变形。当皱褶层20设置于第一定型层110时，第一结合部130与定型部250利用超音波、重力或热能的能量，并以滚动压合或直接压合的方式压合，使第一结合部130与定型部250相结合。除了上述结合第一结合部130及定型部250的方法外，另可运用胶合或车缝方式结合第一结合部130及定型部250，并结合第一结合部130及定型部250。当用户配戴过滤结构1而面罩本体10产生变形时，皱褶层20的所述皱褶210不会直接受到面罩本体10的变形的影响，所以可避免所述皱褶210产生变形，如此较不影响过滤结构1的过滤效果及透气度。
本实施例的面罩本体10与皱褶层20在未组装前就已经预先成型为立体状，当然本实施例的面罩本体10与皱褶层20在未组装前可为平面状，然后面罩本体10与皱褶层20堆叠设置于立体模具，利用超音波、重力或热能的能量，并以滚动压合或直接压合的方式压合面罩本体10与皱褶层20，面罩本体10及皱褶层20同时成型为立体状，使面罩本体10的第一定型层110与皱褶层20的周缘同时分别形成第一结合部130及定型部250，也使第一结合部130与定型部250相结合。
此外，本实施例的皱褶层20可经过静电处理，使皱褶层20带有静电荷。当用户配戴过滤结构1时，皱褶层20的所述静电荷可吸附由过滤结构1的外侧进入过滤结构1的内侧的空气内所含有的细小粉尘，以增进过滤结构1的过滤效果。
请参阅图2A与图2B，其是本发明的第二实施例的过滤结构的皱褶层的示意图；如图所示，第一实施例的皱褶层20为单片皱褶片并经压合处理而形成立体状的皱褶层20，而本实施例的皱褶层20包含第一皱褶片220与第二皱褶片230，第一皱褶片220及第二皱褶片230均具有多个皱褶210，第一皱褶片220具有第一接合边221，而第二皱褶片230具有第二接合边231，第一皱褶片220的第一接合边221与第二皱褶片230的第二接合边231相接合。其中第一接合边221与第二接合边231连接所述皱褶210，以固定所述皱褶210，进而避免第一皱褶片220及第二皱褶片230被撑开后，所述皱褶210因被撑开而产生变形。其中，本实施例的第一接合边221与第二接合边231呈弧形，其也可为其他形状，例如直线，在此不再赘述。
当撑开第一皱褶片220及第二皱褶片230时，并将已撑开的第一皱褶片 220及第二皱褶片230设置于立体模具上并利用压合处理形成立体状的皱褶层20，皱褶层20的几何形状与面罩本体10的几何形状相对应。
上述第一皱褶片220或第二皱褶片230由成型片经成皱处理，以形成具有所述皱褶210的成型片，进而形成第一皱褶片220或第二皱褶片230，其中成型片240的材质为无纺布、网状织物或其他材质。下述以第一皱褶片220为例，请一并参阅图3A到图3D，其绘示第一皱褶片220的剖面图，每一个成型片240经成皱处理而形成所述皱褶210，进而形成第一皱褶片220，所述皱褶210的形状可呈连续的波浪状(如图3A)、连续的锯齿状(如图3B及图3C)、不连续的锯齿状(如图3D)、不连续的波浪状或不规则状，在此不限制所述皱褶210的几何形状。
请参阅图4及图5，其是本发明的第六实施例的过滤结构的皱褶层的剖面图及第一皱褶片的示意图；如图所示，上述实施例的皱褶层20的第一皱褶片220与第二皱褶片仅分别由单一成型片240制作，而本实施例的皱褶层20的第一皱褶片220或第二皱褶片是由多个成型片240叠合而成，然后所述成型片240经由成皱处理而形成所述皱褶210，所述成型片240的所述皱褶210相叠合，如此可增加第一皱褶片220或第二皱褶片的所述皱褶210的结构强度，避免所述皱褶210产生变形，也可以提高过滤结构1的过滤效果，其中所述成型片240的材质可为无纺布、网状织物或其他硬性材质与软性材质的组合。
请参阅图6，其为本发明的第七实施例的过滤结构的皱褶层的示意图；如图所示，本实施例的皱褶层20与上述实施例的皱褶层20不同在于，本实施例的皱褶层20包含多个皱褶片211(三片以上)，每一个皱褶片211具有所述皱褶210与至少一个接合边2110，每一个皱褶片211的接合边2110与相邻的所述皱褶片211的所述接合边2110相接合，如此撑开后的所述皱褶片211经压合处理可形成立体状的皱褶层20。
请参阅图7，其是本发明的第八实施例的过滤结构的示意图；如图所示，本实施例与上述实施例不同在于，本实施例的过滤结构1更包含第二定型层120及保护层140，即此实施例包含第一定型层110与第二定型层120，第二定型层120呈立体状，且其几何形状对应面罩本体10的第一定型层110及皱褶层20的几何形状。第二定型层120并设置于皱褶层20的内侧，而第一定型层110设置于皱褶层20的外侧，如此第二定型层120与第一定型层110相间隔，即皱褶层20设置于第一定型层110与第二定型层120之间。由此可知，第一定型层110与第二定型层120可固定皱褶层20的几何形状，如此可避免皱褶层20变形。保护层140罩设于面罩本体10的第一定型层110的外侧，并与皱褶层20相间隔，以保护面罩本体10，并防止面罩本体10沾染脏污。在本实施例中，保护层140也呈立体状，即保护层140的几何形状对应于面罩 本体10的几何形状。其中第一定型层110、第二定型层120、保护层140及皱褶层20可同时形成或者分开形成，在此不再赘述。
请参阅图8，其是本发明的第九实施例的过滤结构的示意图；如图所示，本实施例与第八实施例不同在于，面罩本体10及皱褶层20的位置相置换，皱褶层20设置于面罩本体10的外侧，如此第二定型层120设置于皱褶层20的外侧，而与面罩本体10的第一定型层110相间隔，保护层140设置于第一定型层110的内侧，而与皱褶层20相间隔。由上述图7与图8的实施例可知，不论面罩本体10及皱褶层20的放置位置为何，第二定型层120及保护层140的设置位置会随的变动，而包覆面罩本体10及皱褶层20，以保护面罩本体10及皱褶层20，进而避免皱褶层20与所述皱褶210产生变形，并固定皱褶层20与所述皱褶210的形状。
此外，第八实施例及第九实施例的第二定型层120的周缘具有第二结合部121，第二定型层120的第二结合部121可与皱褶层20的定型部250或/与面罩本体10的第一结合部130相结合，而组装为过滤结构1。然第八实施例及第九实施例的保护层140的周缘具有第三结合部141，保护层140的第三结合部141可与面罩本体10的第一结合部130、皱褶层20的定型部250或/与第二定型层120的第二结合部121相结合，而组装为过滤结构1。
请参阅图9，其是本发明的第十实施例的过滤结构的示意图；如图所示，本实施例与第九实施例不同在于，本实施例具有二个保护层140，二个保护层140分别设置于面罩本体10的第一定型层110的内侧与第二定型层120的外侧，而包覆第一定型层110及第二定型层120，进而包覆皱褶层20，第一定型层110第一结合部130和第二定型层120的第二结合部121同时与二个保护层140的二个第三结合部141相结合，以形成过滤结构1。
请参阅图10，其为本发明的第十一实施例的过滤结构的示意图；如图所示，本实施例与上述实施例不同在于，上述实施例的面罩本体10为杯状，而本实施例的面罩本体10的几何形状为鸭嘴状，然皱褶层20对应面罩本体10的几何形状，其也呈鸭嘴状，特举此例，即表示本发明的过滤结构1可应用于各种形状的口罩，如：对开式立体口罩(如图11所示)与三面式立体口罩等。
本实施例的皱褶层20包含第一皱褶片220及第二皱褶片230，且第一皱褶片220及第二皱褶片230上下叠合，第一皱褶片220的第一接合边221与第二皱褶片230的第二接合边231相接合。在本实施例中，第一皱褶片220的左右两周边为第一接合边221，而第二皱褶片230的左右周边为第二接合边231。此外，第一皱褶片220与第二皱褶片230具有所述皱褶210，并分别具有第二定型部260，本实施例的第二定型部260与上述皱褶层20的定型部250不同在于，本实施例的第二定型部260设置于第一皱褶片220或第二皱褶片 230的周缘内的所述皱褶210上，并连接第一皱褶片220或第二皱褶片230的所述皱褶210，以固定所述皱褶210，而防止所述皱褶210产生变形。在本实施例中，可利用超音波、重力或者热能的能量，以滚动压合或者直接压合的方式于所述皱褶210压出第二定型部260。除此的外，运用胶合或者车缝方式连接所述皱褶210而形成第二定型部260。
另外，所述皱褶210仅形成于皱褶层20，并未形成于面罩本体10，所以当用户配戴过滤结构1而导致面罩本体10有所变形时，可避免所述皱褶210随着面罩本体10的变形而产生变形。本实施例的第二定型部260为线性压条。另，如图12所示，在所述皱褶210上形成多个第二定型部260，每一个第二定型部260也可为一个压点，本实施例的第二定型部260仅连接相邻的所述皱褶210，与上述实施例的第二定型部260不同在于，本实施例的第二定型部260仅连接部分的所述皱褶210，所述第二定型部260呈不规则排列，当然也可呈线状排列，只要达到固定所述皱褶210的功效即可，如此可有效避免所述皱褶210产生变形而影响过滤结构1的过滤效果，第十一实施例至第十三实施例的第二定型部260也可以运用于其他实施例，在此不再赘述。
此外，本实施例的面罩本体10及皱褶层20分别具有第一结合部130及定型部250，皱褶层20置放于面罩本体10时，第一结合部130与定型部250相对应并进而相结合，以形成鸭嘴状的过滤结构1。其中，本实施例的第一结合部130及定型部250与第一实施例不同在于，本实施例的第一结合部130及定型部250非往面罩本体10的外侧凸出的凸缘。
请参阅图13及图14，其是本发明的第十四实施例的过滤结构的皱褶层的示意图及皱褶布的示意图；如图所示，本实施例提供另一种过滤结构1，其包含皱褶层20及固定层30，皱褶层20设置于固定层30，固定层30与皱褶层20的周缘内的多个皱褶210间具有至少一个连接部310，连接部310连接固定层30与皱褶层20，其中固定层30也可设置于皱褶层20的内侧。然皱褶层20及固定层30均呈立体状，其通过皱褶布40经压合处理而形成，皱褶布40包含皱褶片410及固定片420，本实施例的皱褶片410与上述实施例的皱褶片相同，其均由至少一个成型片经成皱处理而形成具有多个皱褶210的皱褶片410，皱褶片410的制造方式已在上述实施例说明，在此不再赘述。然固定片420设置于皱褶片410上，利用超音波、重力或热能的能量，并以滚动压合或直接压合的方式压合固定片420及皱褶片410，且与固定片420与皱褶片410之间形成连接部310，其中连接部310位于皱褶片410的相邻的二个皱褶210间的凹陷处220，如此使皱褶片410的所述皱褶210固定于固定片420上而形成皱褶布40，以使皱褶片410的所述皱褶210不会散开，进而不会降低利用皱褶布40制成的过滤结构1的过滤效果及透气度。当然连接部310的位置可依据制造过程的设定而位于皱褶片410的所述皱褶210的任一位置，并不 限于位于相邻的二个皱褶210间的凹陷处220。
最后将皱褶布40设置于立体模具，然利用超音波、重力或热能的能量，并以滚动压合或直接压合的方式压合皱褶布40，并形成呈立体状的过滤结构1，即同时形成呈立体状的固定层30及皱褶层20，然固定层30及皱褶层20的周缘形成定型部250。本实施例的过滤结构1的固定层30可固定所述皱褶层20的所述皱褶210，同时也保护皱褶层20的表面并维持皱褶层20为立体状，即同时具有上述实施例的定型层及设置于皱褶层的第二定型部的功能，所以使本实施例的过滤结构1的结构较为简单，也能简化过滤结构1的制造过程。当然本实施例的皱褶布40利用压合处理为上述实施例的皱褶层，并应用于上述实施例中，举例说明：若欲形成第二实施例的皱褶层也可利用二个皱褶布40经压合处理形成，其中每一个皱褶布40的边缘为接合边，每一个皱褶布40的接合边相接合，同理，第七实施例的皱褶层也可利用四皱褶布40相接合并经压合处理形成。此外，上述实施例的定型层或保护层等结构可应用于本实施例中，在此不再赘述。
综上所述，本发明是一种过滤结构，其主要将皱褶层设置于面罩本体，皱褶层因具有多个皱褶，使其表面积大于面罩本体的表面积，而有效提升过滤结构的过滤面积，进而提高过滤效果，且降低过滤结构的内外压差，进而提升过滤结构的透气度与使用舒适度。此外，皱褶层呈立体状，而设置于面罩本体，以避免皱褶层的所述皱褶变形而导致透气度降低。另外，皱褶层更具有定型部，而用于固定皱褶层的所述皱褶，以避免所述皱褶变形，如此避免透气度降低。然皱褶层的表面更设有固定层，固定层与皱褶层的所述皱褶之间利用所述连接部连接，并可省略定型层、保护层及第二定型部的设置，以简化过滤结构的结构及制造方法。
以上所述，仅是本发明的较佳实施例而已，并非对本发明做任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专业的技术人员，在不脱离本发明技术方案范围内，当可利用上述揭示的技术内容做出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所做的任何简单修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
