具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明的一部分实施例， 而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明提出一种浮潜呼吸器。请参阅图1至3，在本发明实施例中，该浮潜呼吸器1包括面罩10、第一呼吸管组件20和呼气单向阀30。其中，面罩10包括外面罩11和呼吸罩12，呼吸罩12设于外面罩11内，且呼吸罩12设有呼吸腔121。第一呼吸管组件20包括第一呼吸管21和吸气单向阀22，第一呼吸管21通过吸气单向阀22与呼吸罩12连接；或者，吸气单向阀22设于第一呼吸管21内，第一呼吸管21与呼吸罩12直接连接。呼气单向阀30与外面罩11和呼吸罩12连接安装。吸气时，吸气单向阀22导通，呼气单向阀30截止，外部空气由第一呼吸管21进入呼吸腔121；呼气时，呼气单向阀30导通，吸气单向阀22截止，呼出的气体由呼吸腔121流向外面罩11的外部。
需要强调的是，在第一呼吸管21通过吸气单向阀22与呼吸罩12连接的情况下，吸气单向阀22设置得相对呼吸罩12距离比较近，相对于吸气单向阀22设置得相对呼吸罩12距离比较远的情况，能够在吸气时减少漏气，形成更明显的负压，从而吸入更多的外界气体，实现更好的换气效果。
具体地，面罩10用于穿戴，帮助人们在水下自由呼吸。外面罩11主要用于保护面部，通常，外面罩11整体采用透明材料制成，以便于在水中具有较好的视野，当然也可仅使对应眼部的部分采用透明材料制成，使得造型多变。呼吸罩12安装于外面罩11内，用于呼吸穿戴，呼吸罩12设有呼吸腔121，使用时通过呼吸腔121进行呼吸，同时通过呼吸罩12将呼吸部分与眼部分隔，避免呼出的气体作用于外面罩11上产生雾气，影响视野。优选地，呼吸罩12采用硅胶材料制成。
为改善浮潜呼吸器1的呼吸结构，避免吸入的空气与呼出的二氧化碳气体混合，本实施例中采用了第一呼吸管组件20和呼气单向阀30。
第一呼吸管组件20包括第一呼吸管21和吸气单向阀22(也称正向单向阀)，使第一呼吸管21设于外面罩11的外侧，同时在外面罩11上设置第一安装孔111，以实现第一呼吸管21与吸气单向阀22的安装。在此，第一呼吸管21与吸气单向阀22可采用两种安装方式：一种是使第一呼吸管21通过吸气单向阀22穿过第一安装孔111与呼吸罩12连接安装，以连通呼吸腔121和外界环境，吸气单向阀22可安装于第一呼吸管21的任意位置，优选地， 吸气单向阀22设置于第一呼吸管21的底端，以使第一呼吸管21具有最长的长度，使用中对浮潜深度具有较好的灵活性和适应性。另一种是将吸气单向阀22设置于第一呼吸管21内，第一呼吸管21穿过第一安装孔111与呼吸罩12连接安装。通过采用吸气单向阀22，使吸气时，第一呼吸管21向呼吸腔121的方向连通，空气只能通过第一呼吸管21流入至呼吸腔121，形成进气通道。
呼气单向阀30(也称反向单向阀)与外面罩11和呼吸罩12连接安装，使呼吸腔121与外界连通。在呼气时，气体通过呼气单向阀30呼出至外部，防止气体的回流，并且直接通过呼气单向阀30呼出，由于呼出通道较短，气体能够被迅速排出，进一步避免空气与呼出气体的混合。并且，由于后述V形条14与防护垫13的设置，使得面部与外面罩11及呼吸罩12更为紧贴，这样能够防止呼气时气体从外面罩11与面部之间的缝隙漏出，影响直接从呼气单向阀30排气的效果；另外，也能够防止呼气时气体从V形条14与面部之间的缝隙漏出到眼部区域(即后述的空腔112)，影响排气效果。
由此可见，通过采用第一呼吸管组件20和呼气单向阀30，分别形成第一呼吸管21与呼吸罩12连通的进气通道，空气只能进；呼气单向阀30形成的呼出通道，空气可瞬间、大量、迅速排出。将呼吸系统中的呼、吸机械式分离，有效避免呼吸罩12内的呼、吸气体混合。
本发明技术方案通过采用面罩10、第一呼吸管组件20和呼气单向阀30，一方面，使第一呼吸管组件20中的第一呼吸管21通过吸气单向阀22与面罩10的呼吸罩12连接，或者使吸气单向阀22设于第一呼吸管21内，第一呼吸管21与呼吸罩12连接，以在吸气时，吸气阀导通，空气通过第一呼吸管21流入至呼吸腔121内；另一方面，使呼气单向阀30与面罩10的外面罩11和呼吸罩12连接安装，以在呼气时，呼气单向阀30导通，呼出气体通过呼气单向阀30流出至外部。通过第一呼吸管20安装了吸气单向阀22，使空气只能进；同时二氧化碳的呼出通过呼出单向阀30瞬间、大量排出，气体顺畅排出，并且不进水。特别针对呼吸系统进行了创新，将呼、吸进行机械式分离，保证呼吸腔121内永远是新鲜空气，将生命安全真正的通过该系统得到保证，提高呼吸器1的安全使用性能，真正实现水下自由呼吸。
参阅图2，浮潜呼吸器1还包括第二呼吸管组件40，第二呼吸管组件40 包括第二呼吸管41和单向阀42，第二呼吸管41通过单向阀42与呼吸罩12连接；或者，单向阀42设于第二呼吸管41内，第二呼吸管41与呼吸罩12连接。采用第二呼吸管组件40，通过第二呼吸管41与呼吸罩12连通，可增加呼吸罩12的进气量或呼气量，提高浮潜呼吸器1的使用性能。
本实施例中，单向阀42可采用吸气单向阀22，第二呼吸管41通过吸气单向阀22与呼吸罩12连接；或者，吸气单向阀22设于第二呼吸管41内，第二呼吸管41与呼吸罩12连接。由于浮潜运动在水下的时间较长，通过增加呼吸罩12的空气进气量，有利于显著提高产品的使用体验。因此，第二呼吸管组件40中单向阀42采用吸气单向阀22，使空气通过第二呼吸管41流入至呼吸腔121，保证了呼吸腔121中的空气量，提高使用效果。当然了，单向阀42也可采用呼气单向阀30，以提高呼气排出率。
参阅图2及图3，外面罩11的内侧面与呼吸罩12的外侧面之间形成有空腔112，呼吸罩12设有连通空腔112与呼吸腔121的通孔122。通过呼吸罩12安装于外面罩11内，使外面罩11内形成不同的区域，呼吸罩12内有呼吸腔121，呼吸罩12外与外面罩11之间形成有空腔112。在呼吸罩12上设置通孔122，使呼吸腔121与空腔112连通，可使进入呼吸腔121的空气通过通孔122流入空腔112，形成临时的空气存放空间，增加空气的存放量。以在水没入第一呼吸管21和第二呼吸管41时，延长于水下的使用时间，提升产品的使用效果。
参阅图3，此外，浮潜呼吸器1还包括V形条14，V形条14设于呼吸罩12的上部以用于与人脸贴合。通过V形条14，使呼吸罩12与人脸具有更好的贴合效果，不仅有利于增强密封效果，而且使穿戴更加舒适，有利于提升穿戴体验。硅胶具有较好的柔韧度，V形条14优选采用硅胶材料。
在一个实施例中，如图1及图2所示，呼气单向阀30包括第一呼气单向阀31和第二呼气单向阀32。采用两个呼气单向阀30，使两个呼气单向阀30均与呼吸罩12和外面罩11连接安装，以在呼气时，至少一呼气单向阀30导通，即可根据需要，在实际应用中，使一个呼气单向阀30导通，或者两个呼气单向阀30同时导通，或者其中一个呼气单向阀30导通，使另一呼气单向阀30根据呼气量控制呼气单向阀30的导通或关闭。通过呼气单向阀30的设置改变或增加呼出气体的流出空间，使呼出气体能够迅速排出，显著提高呼 气效率，有效避免空气与呼出气体在呼吸腔121内的混合。两个呼气单向阀30可设置于呼吸罩12的任意位置，在本实施例中，使第二呼气单向阀32正对于口部设置于呼吸罩12，第一呼气单向阀31正对于鼻子设置于呼吸罩12的下部，使其沿呼出气体的流动方向进行设置，进一步提高气体的流出速率。
由于呼气单向阀30直接将呼吸腔121与外部导通，使气体流出的距离较短；并且两个呼出单向阀30同时导通增大气体的流出体积，使呼出气体能够迅速流出，从而显著提高呼气效率，避免空气与呼出气体的混合，使发生胸闷、窒息的不适感明显减少，极大的提升了呼吸器的安全使用性能。
可选地，呼气时，第一呼气单向阀31导通；第二呼气单向阀32连接安装有气流感应器(图未示)，以根据呼气量控制第二呼气单向阀32的导通或关闭。通过采用气流感应器，在呼气量大时，第二呼气单向阀32感应到气流增大后导通，增大气体的流出空间，使呼出气体迅速流出；呼气量小时，第二呼气单向阀32关闭，呼出气体通过第一呼气单向阀31排出，增加了使用的灵活度，使得设计更加人性化。
在另一本实施中，如图4所示，面罩10具有与呼吸腔121相连通的穿戴开口120，穿戴开口120可与人体的脸部相贴合，并使得人体的嘴、鼻子、眼睛位于呼吸腔121内。当使用者佩戴浮潜呼吸器1游泳或潜水时，面罩10的穿戴开口120与人体的脸部密封贴合，从而防止水进入呼吸腔121内。
进一步地，如图4所示，穿戴开口120上设置有防护垫13，防护垫13沿穿戴开口120的边缘延伸呈环状设置，且防护垫13套设于穿戴开口120边缘的外周面上；穿戴开口120边缘的外周面上套设有压圈140。如图4至图7所示，压圈140的内周面包括沿其轴向依次设置的固定部141和压接部142，压接部142靠近穿戴开口120设置，固定部141与穿戴开口120边缘的外周面相连接，压接部142将防护垫13密封压持固定于穿戴开口120边缘的外周面。
设置防护垫13的目的是为了更好地实现穿戴开口120与人体脸部的贴合，从而达到密封效果和提高人体的接触舒适度。该防护垫13为弹性或柔性材料所制成，其中防护垫13优选为质地柔软的硅胶件，硅胶件具有防水性好、对人体皮肤无毒无害的优点，从而既能起到密封防水的左右，又可与人体皮肤紧密接触提高人体的接触舒适度。
压圈140套设于穿戴开口120边缘的外周面，从而将防护垫13压持固定 于面罩本体10上。为了保证压圈140能够可靠地将压圈140固定在面罩本体10上，本实施例中，压圈140的内周面包括固定部141和压接部142，压接部142将防护垫13密封压持固定于穿戴开口120边缘的外周面；固定部141与穿戴开口120边缘的外周面相连接，从而保证压圈140与面罩10的可靠连接，从而确保防护垫13能够可靠地夹持于压圈140和面罩10之间，减少防护垫13松动的风险，从而保障防护垫13具有较佳的密封效果。
在本实施例中，上述压圈140应具有较高的强度，以将防护垫13牢靠地压持于面罩本体10上。工程塑料具有强度高、密度小、成本低廉等优点，进而该压圈140可以是由工程塑料所制成的。其中，制备该压圈140的工程塑料包括但不限于聚乙烯(PE)、聚丙烯(PP)、聚氯乙烯(PVC)、聚碳酸酯(PC)、ABS塑料。
进一步地，为了保证压圈140的固定部141与面罩10的可靠连接，参照图5至图7，上述固定部141包括自压圈140的内周面沿周向朝内凸设的第一环形挡筋143和第二环形挡筋144，第一环形挡筋143和第二环形挡筋144之间间隔形成一环形插槽145；穿戴开口120边缘的外周面设有与环形插槽145相插接配合的环形固定筋130。如此一来，环形固定筋130与环形插槽145相配合，从而将压圈140固定于面罩10上，防止压圈140从面罩10上脱落，使得防护垫13能紧密地夹持于压圈140和面罩10之间。
可以理解的是，上述环形固定筋130可密封插设于环形插槽145内，从而在压圈140和面罩10之间形成第一道密封防水结构，从而减少面罩10的穿戴开口120处漏水的几率。
在另一个实施例中，如图8所示，第一呼吸管组件20可转动地安装在面罩10上，如此一来，第一呼吸管组件20可相对面罩10转动，从而当使用者调整游泳姿态时，能保证第一呼吸管组件20的进气口211可始终位于水面之上。也就是说，浮潜呼吸器1不仅适用于自由泳、蛙泳等游泳姿势，还适用于仰泳的游泳姿势，从而使得浮潜呼吸器1的使用场景更加广泛，大大提高了浮潜呼吸器1的适用性。
在一些较佳实施方式中，该第一呼吸管组件20可相对面罩10进行360度转动，从而更便于使用者对第一呼吸管组件20的转动位置进行调节，以适应更多的游泳姿态。
如上所述，第一呼吸管组件20可以直接安装在呼吸罩12上，或者第一呼吸管21采用连接件间接地安装在呼吸罩12上。在本实施例中，上述第一呼吸管组件20优选通过吸气单向阀22间接地安装在呼吸罩12上，其具体安装结构如下：
如图8所示，浮潜呼吸器1包括吸气单向阀22，吸气单向阀22具有呈相对设置的第一端和第二端，呼吸罩12上设有第一安装孔111，第一端与安装孔111密封连通，第二端与第一呼吸管21的一端密封连通，且第一呼吸管21的一端与第二端转动连接。
可以理解的是，吸气单向阀22不需要相对呼吸罩12转动，从而提高了吸气单向阀22的第一端与呼吸罩12的连接密封性，同时也简化了呼吸罩12的结构，有助于降低面罩10的注塑制造成本。
此外，在本实施例中，优选在吸气单向阀22内设置单向阀膜片，该单向阀膜片用以在人体吸气时将第二端和第一端依次单向导通。即当人体吸气时，呼吸腔121内产生负压，从而使得单向阀膜片朝呼吸腔121的一侧收缩卷绕，从而使得第二端和第二端依次单向导通，空气从第一呼吸管组件20经过吸气单向阀22吸入呼吸腔121内；当人体呼气(或单发阀膜片处于常规状态时)，单向阀膜片展开于吸气单向阀22内，从而将吸气单向阀22内部隔离，使得第一端和第二端无法导通，避免呼吸腔121内的空气经过吸气单向阀22从第一呼吸管组件20排出。
进一步地，参照图8及图9，上述吸气单向阀22包括沿轴向依次设置的第一连接段310、隔挡部320及第二连接段330，第一连接段310适配贯穿第一安装孔111，隔挡部320凸出于第一连接段310的外周面，以限制第一连接段310的插入深度；浮潜呼吸器1还包括位于呼吸腔121内的固定套筒50，固定套筒50可拆卸地安装至第一连接段310的外周面，以将吸气单向阀22压持固定于第一安装孔111处；第一呼吸管组件20的一端与第二连接段330相连接。
可以理解的是，第一连接段310靠近第一端设置，第二连接段330靠近第二端设置，固定套筒50可通过螺纹配合的方式安装在第一连接段310的外周面上，此时第一安装孔111的两侧分别与隔挡部320和固定套筒50抵接，即第一安装孔111的孔壁夹持固定于隔挡部320和固定套筒50之间，从而将 吸气单向阀22安装至呼吸罩12上。
在另一实施例中，请参阅图10至图14，吸气单向阀22具体包括：
阀体221，阀体221呈筒状设置，阀体221轴向上的两端呈敞口设置，阀体221内设置有安装板222，安装板222的周缘连接阀体221的内壁，安装板222上开设有通气孔223；
阀片224，阀片224安装于安装板222上，以将通气孔223打开或盖合，阀体221内且位于安装板222的两侧均设置有可容纳阀片224的容纳空间。
具体而言，安装板222可以与阀体221一体成型，也可以通过焊接、粘接等方式将安装板222固定于阀体221上，也可以通过可拆卸的安装方式固定在阀体221上。为了生产方便，提高加工效率，较佳地，安装板222与阀体221一体成型设置。通气孔223的形状没有严格要求，只要能够通气即可。较佳地，安装板222上平均分隔有八个呈三角形状的通气孔223，如此使得安装板222具有较高的强度，且使得通气孔223占有较大的空间，使得通气较顺畅。阀片224安装于安装板222上的方式没有严格限制，只要是可拆卸的安装方式即可，如此可以将阀片224设置在安装板222的任何一侧，当需要调整吸气单向阀22的通气方向时，只需要将阀片224安装到安装板222的另一侧，即可调整吸气单向阀22的通气方向。例如：当阀片224放置在安装板222的一侧时，吸气单向阀22则实现进气的功能，当阀片224设置在安装板222的另一侧时，吸气单向阀22则实现排气的功能，如此使得吸气单向阀22的通气方向可以改变，不局限于单一方向通气。
本发明通过将吸气单向阀22的阀体221内安装板222的两侧均设置有可容纳阀片224的容纳空间，使得吸气单向阀22的阀片224可以放置在安装板222的任一侧。将阀片224放置在安装板222的不同侧，可以实现不同方向的通气，进而实现通气方向的切换，不再只限制于单一方向的通气。
为了便于阀片224安装于安装板222上，在一实施例中，请继续参阅图10至图14，安装板222的中部开设有第二安装孔225，阀片224包括片体224a和连接片体224a的安装柱224b，安装柱224b穿过第二安装孔225固定于安装板222上。安装柱224b上设置有卡槽，安装柱224b通过卡槽将阀片224卡设于安装板222上，进而将阀片224固定在阀体221上。
进一步地，安装板222的周缘与阀体221的内壁之间还设置有一环柱体 226，片体224a搭接于环柱体226轴向上的其中一个端面上。片体224a可以搭接于环柱体226轴向上的任一一个端面上，搭接在不同的端面上则可以实现不同的通气方向。通过设置环柱体226，使得片体224a搭接在环柱体226上，在吸气单向阀22不通气的情况下，片体224a与环柱体226之间具有较好的密封性。
为了使片体224a与环柱体226之间具有更佳的配合关系，在其中一较佳的实施例中，请参阅图10、图12和图13，环柱体226轴向上的端面上凸设有一凸筋226a，所述凸筋226a的截面呈三角形设置。所述片体224a上靠近其周缘处则搭接在所述凸筋226a上，对片体224a与环柱体226之间具有进一步的密封效果，在不通气的情况下，具有双重的密封效果。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
