具体实施方式
下面结合具体实施例对本发明作进一步说明，以使本领域的技术人员可以更好的理解本发明并能予以实施，但所举实施例不作为对本发明的限定。
请参阅图1、图2及图3，分别为本发明第一实施例的立体分解示意图、另一视角的立体分解示意图、以及使用状态示意图。本发明提供一种结构改进的个人用空气过滤装置，其用以配置于人体鼻孔下方(如图3所示)，可将人体于呼吸时所吸入的空气先予以过滤后，再供人体吸入，以确保所吸入的空气的洁净度，并可进一步避免人体呼吸道因不洁的空气所造成的感染等问题。该个人用空气过 滤装置包括一滤器壳体1、一控制单元2、以及一过滤单元3；其中：
该滤器壳体1内呈中空，并可由一前盖10与一后盖11相互盖合而成，该滤器壳体1上还设有进气孔100与出气孔110。在本发明所举的实施例中，所述进气孔100设于前盖10上，并可通过一装饰件13覆盖于所述进气孔100前方但须维持进气孔100的畅通，而所述出气孔110设于后盖11上。且该滤器壳体1因其内部中空而形成有一容腔111，该容腔111可通过前盖10与后盖11相互盖合后而形成，而所述进气孔100、出气孔110均与该容腔111相通，以供进气孔100与出气孔110可分别作为空气进、出入容腔111内所用。另，所述进气孔100或出气孔110均可设置为一个或多个、或其它任何可供空气通过的型态。
该控制单元2设于上述滤器壳体1的容腔111内，并可包含一进气控制阀20与一出气控制阀21。在本实施例中，该进气控制阀20又包含一进气阀门200与一进气阀塞201，该进气阀塞201控制进气阀门200作单向的开启或闭合而设于其上，该进气阀门200上具有进气口202，可设有纳米杀菌网(图略)；该出气控制阀21亦包含一出气阀门210与一出气阀塞211，该出气阀塞211控制出气阀门210作单向的开启或闭合而设于其上，该出气阀门210上具有出气口212，且出气阀塞211控制的方向与进气阀塞201相反。此外，该进气阀门200与出气阀门210可横向并列而构成一片状体。
另，如图6所示，该进气控制阀20与上述进气孔100之间于容腔111内形成有进气流道101，该进气控制阀20与出气控制阀21之间于容腔111内形成有供气流道102，而如图7所示，该出气控制阀21与上述出气孔110之间于容腔111内则形成有出气流道103，故进气流道101可通过进气控制阀20的开启而以单向连通至气通道102连通，而供气流道102可通过出气控制阀21的开启而以单向连通至出气通道103。又，如图1及图5所示，为了便于空气于容腔111内的流向，可于控制单元2上设有一位于进气流道101内的阀板4，该阀板4与呈片状体的控制单元2叠置而一并组设于后盖11上，且该阀板4相对于出气阀门210而具有一分隔部40、相对于进气阀门200则具有一缺口部41，分隔部40可防止进入的空气不慎通过出气阀门210，而缺口部41则可供进入的空气确实通过进气阀门200。
该过滤单元3设于上述滤器壳体1的进气流道101内，以阻隔于滤器壳体1 的进气孔100与控制单元2的进气控制阀20之间，借以确保被吸入滤器壳体1内的空气，可先通过该过滤单元3进行过滤，该过滤单元3可为一活性碳组合过滤网。此外，亦可于该过滤单元3表面上涂抹如香精油等香料(图略)，以提供洁净的空气进一步的清香气味。
再者，上述滤器壳体1上方设有对应人体鼻孔的呼吸管12，以对应并插入人体鼻孔内，且所述呼吸管12连通至滤器壳体1的容腔111内，并连通至容腔111的供气流道102。又，呼吸管12内具有一吸气孔120，呼吸管12上可进一步套设一鼻塞套121，且鼻塞套121仍维持吸气孔120与人体鼻孔的畅通。而在本实施例中，该呼吸管12设于滤器壳体1的后盖11上方，且该二呼吸管12间的距离可作调整，以配合不同的使用者使用。
因此，借由上述的构造组成，即可得到本发明的结构改进的个人用空气过滤装置。
据此，请一并参阅图4、图5及图6所示，当人体吸入空气时，外界的空气会由上述滤器壳体1的进气孔100进入其内，并先通过上述过滤单元3进行过滤，以获得洁净的空气。之后，空气再由容腔111内的进气流道101推抵进气控制阀20的进气阀塞201，因为进气控制阀20控制单向的原故，使得空气仅得由此方向推开进气阀塞201而通过进气阀门200，以来到供气流道102，再借由呼吸管12供人体吸入所述洁净的空气。
反之，当人体将上述所吸入的空气吐出时，所吐出的空气由呼吸管12来到供气流道102，此时因出气阀塞211控制的方向与进气阀塞201相反，因此进气阀塞201会闭合进气阀门200，并推抵出气控制阀21的出气阀塞211，因为出气控制阀21控制单向的原故，使得空气仅得由此方向推开出气阀塞211而通过出气阀门210，以来到出气流道103，进而由出气孔110排出滤器壳体1外。附带一提的是：于上述吸气时，因出气阀塞211会闭合出气阀门210，所以外界的空气不会由出气孔110通过出气控制阀21而进入供气流道102。
此外，如图3所示，本发明可还包括一配戴件5，该配戴件5连接于上述滤器壳体1二端处上，以方便供人体配戴时固定于脸部上。
再者，如图8及图9所示，为本发明的第二实施例。其中，请一并参阅图10及图11所示，该控制单元2仅具有上述出气控制阀21，所述进气流道101则 形成于的该控制单元2与上述进气孔100之间的容腔111内，且上述呼吸管12直接与进气流道101连通；通过所述过滤单元3设于该进气流道101内且阻隔于进气孔100与呼吸管12之间，使人体吸气时，外界的空气由进气孔100通过过滤单元3进行过滤后，能直接由进气流道101进入呼吸管12并供人体吸入洁净后的空气。反之，如图12所示，当人体吐气时，所吐出的空气由呼吸管12来到腔室11，此时因出气阀塞211控制的方向可被吐出的空气推开，使得空气能通过出气阀门210来到出气流道103，进而由出气孔110排出滤器壳体1外。
因此，借由本发明结构改进的个人用空气过滤装置，不仅可具有较小的体积，在配戴上也仅会占用人体鼻孔下方，不会因过大的体积而占据人体口部等其它部位、甚至影响谈话或发声等动作，故可适合于个人随身使用来提供洁净的空气，以兼具携带上的便利性。
以上所述实施例仅是为充分说明本发明而所举的较佳的实施例，本发明的保护范围不限于此。本技术领域的技术人员在本发明基础上所作的等同替代或变换，均在本发明的保护范围之内。本发明的保护范围以权利要求书为准。
