Description

可加热式呼吸面罩 技术领域
本发明涉及保健器具和医疗器械技术领域，尤其是涉及一种可加热式呼吸面罩。
背景技术
申请人此前申请了专利号为ZL202011121121.3、名称为“加热鼻罩”的中国发明专利，该加热鼻罩解决了在天气较冷干燥时，使用者佩戴防寒面罩、围巾或者口罩之类的防护用品无法达到理想的舒适温度和湿度的技术问题，并解决了鼻炎、鼻塞一类跟呼吸相关疾病的患者在外出时，病情容易复发并影响生活和生产的技术问题。
然而，该加热鼻罩只能罩盖住人体鼻部，人体口部等则是裸露在外的，这样一来，一方面外部有害的粉尘、飞沫、病毒等物质仍将通过人体口部大幅侵入人体，从而对人体产生各种危害，另一方面人体口部呼出的气体(例如唾沫等)将直接飞向周围环境，容易对周围人群造成危害，再一方面冬天户外使用时不能起到挡风作用。而且，该加热鼻罩也不能对人体口部吸入的空气进行过滤。为此产品功能尚不完善，有待于进一步设计改良。
发明内容
本发明的目的在于克服上述现有技术之不足，提供一种功能更加完善且结构设计合理、安装和制作方便、拆卸清理和维护容易的可加热式呼吸面罩。

具体实施方式
下面结合附图给出的实施例对本发明作进一步详细说明。
如图1至图12所示，本实施例提供的一种可加热式呼吸面罩，包括至少可覆盖人体口部和鼻部的面罩本体1，面罩本体1上对应人体鼻部的位置设有鼻部密封环2，鼻部密封环2的内周限定一安装孔3，安装孔3内安装有暖鼻罩4，暖鼻罩4具有可供人体鼻部放入的鼻部容纳空间41， 暖鼻罩4还具有将鼻部容纳空间41与外部连通的呼吸通道42，该呼吸通道42内设有加热部件43，该加热部件43能对自呼吸通道42吸入鼻部容纳空间41的外部空气进行加热，面罩本体1的两侧设置有用以将面罩本体固定在人体面部的佩戴部5。
该可加热式呼吸面罩还包括一可覆盖人体口部和鼻部的柔性过滤罩6，该柔性过滤罩6可选择性地与面罩本体1结合使用或不结合使用。当该柔性过滤罩6与面罩本体1结合使用时，该柔性过滤罩6置于面罩本体1的内侧，并且具体的，该柔性过滤罩6具有鼻罩部分61和口罩部分62，可以将该柔性过滤罩6的鼻罩部分61塞入鼻部容纳空间41内，从而保持柔性过滤罩6在面罩本体1上的固定，接着再通过佩戴部5将该结合有柔性过滤罩6的面罩本体1佩戴到人体面部即可，这样一来，柔性过滤罩6上并不需要额外设置佩戴部件。此外，柔性过滤罩6的材质可以参考现有普通医用防护口罩来设计。
如上所述，当结合有柔性过滤罩6的面罩本体1佩戴到人体面部上使用时，一方面可以通过暖鼻罩4中的加热部件43对人体鼻部吸入的空气进行加热，另一方面可以通过面罩本体1对人体口、鼻等部的遮挡而阻止外部有害物质大幅侵入人体口、鼻部，以及对人体口部呼出的气体如唾沫等进行吸附，并改变人体口部呼出的气体的方向，且起到挡风作用，再一方面还可以通过柔性过滤罩6对人体口、鼻部吸入的空气进行过滤。
当然，用户也可以根据自身情况选择不将柔性过滤罩6与面罩本体1结合使用，此时，将柔性过滤罩6取下即可。此情况下，虽然会失去柔性过滤罩6的空气过滤功能，但面罩的透气性会相对更好。
本实施例中，面罩本体1的内表面上还设有若干位于鼻部密封环2左右两侧的防滑凸筋7。由于在具体制作时，为了确保气密性，鼻部密封环2的内侧面相对于面罩本体1的内表面呈一定厚度凸起，所以防滑凸筋7的设置可以填补面罩本体1两侧临近鼻部密封环2的内表面部分与鼻部密封环2内侧面的厚度差，从而使面罩本体1更好地与人体面部贴合固定，并防止打滑。
本实施例中，暖鼻罩4包括一仿鼻形罩体4a和一底盖4b，仿鼻形罩体4a包括一周壁4a1和一底壁4a2，周壁4a1的内侧表面与底壁4a2的上表面之间形成所述鼻部容纳空间41，底盖4b与底壁4a2的下侧可拆卸 地卡合在一起，呼吸通道42包括开设于底盖4b上的进气口421、开设于底壁4a2上的出气口422和形成于底盖4b与底壁4a2之间且连通于进气口421和出气口422之间的暖鼻罩内部容腔423，加热部件43设置在该暖鼻罩内部容腔423内。
如上所述，底盖4b的上端设有凸起结构的第一环形结合部4b1，底壁4a2的下端设有凹陷结构的第二环形结合部4a21，第一环形结合部4b1上沿周向间隔设置有多个卡筋4b11，第二环形结合部4a21上沿周向间隔设置有多个卡槽4a22。底盖4b与底壁4a2连接时，第一环形结合部4b1嵌入第二环形结合部4a21，且第一环形结合部4b1上的多个卡筋4b11对应卡入第二环形结合部4a21上的多个卡槽4a22，从而实现底盖4b与底壁4a2的可拆卸卡合连接。当需要打开暖鼻罩4时，只需稍用力将仿鼻形罩体4a与底盖4b向脱离方向掰开，让卡筋4b11脱出卡槽4a22即可，这样设计方便对暖鼻罩内部容腔423内的相关结构进行拆卸清理及维护。
该可加热式呼吸面罩还包括控制器8、电缆9、第一导电弹簧片10、第二导电弹簧片11，电缆9一端与控制器8连接、另一端伸入暖鼻罩内部容腔423内。面罩本体1的一侧内表面上设有用以固定电缆9的固定线卡12，从而使电缆9不会任意摆动而影响使用。加热部件43为电热片，第一导电弹簧片10和第二导电弹簧片11分别可拆卸地卡接在该电热片上，电缆9的伸入端设置有第一连接端子91和第二连接端子92，第一连接端子91和第二连接端子92的下端分别与第一导电弹簧片10和第二导电弹簧片11抵接，第一连接端子91和第二连接端子92的上端分别固定在仿鼻形罩体4a的底壁4a2上，这样设计既能确保第一连接端子91和第二连接端子92与加热部件43之间电连接的可靠性，又能方便加热部件43的拆卸清理或更换。
进一步的，加热部件43与仿鼻形罩体4a的底壁4a2及底盖4b之间均设有隔热柱13，这样可以减少加热部件43的热量传导至底壁4a2及底盖4b上，底盖4b的内壁上还设有限位柱4b2，加热部件43上开设有用以供限位柱4b2插入的限位孔431，通过限位柱4b2与限位孔431的配合使得加热部件43不会在暖鼻罩内部容腔423内晃动。
在其它再选实施例中，为了实现加热部件43的定位，也可以是在仿鼻形罩体4a的底壁4a2下表面设置与限位孔431插配的限位柱，或者是在仿鼻形罩体4a的底壁4a2下表面和底盖4b的内壁上同时设置该限位 柱结构。
该可加热式呼吸面罩还包括温度传感器22和传感器保护壳23，传感器保护壳23可拆卸设置在暖鼻罩内部容腔423内，温度传感器22固定安装在传感器保护壳23内，电缆9的伸入端还设置有第三连接端子93和第四连接端子94，温度传感器22上连接有第一导线221和第二导线222，第一导线221和第二导线222穿出传感器保护壳23并分别可拆卸地连接于第三连接端子93和第四连接端子94。这样设计，一方面有利于保护温度传感器22不容易损坏，另一方面助于温度传感器22的拆卸更换。
如上所述，该可加热式呼吸面罩可通过控制器8上的调温按钮来设定加热部件43的加热温度，具体的，该设定的加热温度一般是佩戴者个人使用舒适的一个温度值。加热部件43加热时，温度传感器22用于检测暖鼻罩内部容腔423内的温度数据，并将检测到的温度数据传输给控制器8，当温度数据高于或低于设定的加热温度时，控制器8则控制加热部件43调低或调高加热温度，从而使其保持在该设定温度值，即在设定的加热温度下实现恒温控制，由此可使人体吸入舒适温度的空气。此外，控制器8的具体结构可参照现有技术设计，本发明不再详细赘述。
该可加热式呼吸面罩还可包括与控制器8相适配且通过充电线可拆连接的移动电源19，移动电源19具体可以是充电宝，便于随身携带补充电力。
本实施例中，电缆9伸入端及第一连接端子91、第二连接端子92、第三连接端子93和第四连接端子94均通过注塑工艺固定在仿鼻形罩体4a的底壁4a2上，这样可以更好地避免电缆9伸入端及各端子在使用中出现松动。
本实施例中，底盖4b的内壁上还设有自进气口421向仿鼻形罩体4a的底壁4a2延伸的环形凸台4b3，该环形凸台4b3的外周面与底盖4b的内壁之间形成有储液腔4b4，且该环形凸台4b3与加热部件43之间留有一定距离的注液间隙4b5。使用时，可以将水溶液自进气口421和注液间隙4b5注入储液腔4b4内，从而对人体鼻部吸入的空气起到加湿作用。若将水溶液替换成药液，还可以对人体呼吸系统起到药熏治疗作用。
进一步的，底盖4b的内壁上设有位于环形凸台4b3两侧的两条第一分隔筋4b6，仿鼻形罩体4a的底壁4a2下表面上设有位于出气口422两 侧的两条第二分隔筋4a23，该两条第二分隔筋4a23与该两条第一分隔筋4b6对应贴合在一起，且该两条第二分隔筋4a23与该两条第一分隔筋4b6之间围成的空间即为所述暖鼻罩内部容腔423，这样人体呼出的气体在通过呼吸通道42向外呼出时，可以减少呼出气体在仿鼻形罩体4a的底壁4a2内腔和底盖4b内腔的滞留，进而使人体呼吸更加顺畅。
本实施例中，鼻部密封环2的外侧开口201大于内侧开口202，暖鼻罩4自鼻部密封环2的外侧开口201装入安装孔3内且通过一环形卡件14可拆卸固定。此外，由于鼻部密封环2的内侧开口202小于外侧开口201，所以暖鼻罩4的内侧表面被所述内侧开口202的边缘遮挡而不会凸出于鼻部密封环2。
具体来说，鼻部密封环2的内周壁上设有一环形卡槽203，环形卡件14包括嵌入环形卡槽203的第一环形部141和套裹于暖鼻罩4外侧周缘的第二环形部142，第一环形部141与第二环形部142之间形成有与鼻部密封环2的外侧开口201贴合的环形台阶部143，暖鼻罩4的上端外侧壁上凸设有止挡部401，该止挡部401与第二环形部142的上端止挡配合且二者之间设有相互配合的第一限位凸块15和第一限位凹槽16，暖鼻罩4的底面与第二环形部142的下端之间设有相互配合的第二限位凸块20和第二限位凹槽21，第二环形部142的下端还设有向外延伸且用以托住暖鼻罩4底面的承托部17，暖鼻罩4的两侧分别设有卡块402，环形卡件14的两侧分别设有钩接于对应卡块402的卡钩144。该结构设计使得暖鼻罩4可以较为简便、稳固、美观地可拆卸安装在安装孔3内。
本实施例中，面罩本体1还可覆盖人体耳部，面罩本体1两侧对应人体耳部的位置设有细小结构的透声孔18，这样设计既可以阻止外部有害物质大幅侵入人体耳部，又可以确保人体耳部能够听到外部声音。
本实施例中，佩戴部5包括设置在面罩本体1两侧对应人体耳部位置的挂带51以及设置在面罩本体1两侧尾部的第一魔术粘带52和第二魔术粘带53，第一魔术粘带52和第二魔术粘带53可相互粘接在一起以及可相互脱开。面罩本体1在佩戴到人体面部时，两侧的挂带51分别挂置在人体两侧耳部，第一魔术粘带52和第二魔术粘带53则从人体头部两侧分别绕至后脑勺后相互粘接固定，从而使面罩本体1可以较为简便和稳固地固定在人体面部。
此外，在本实施例中，面罩本体1优选为弹性材质(例如橡胶材质 等)，这样既能确保佩戴在人体面部时的舒适性，又能保证暖鼻罩4和环形卡件14拆装的方便性。暖鼻罩4和环形卡件14则优选为塑料材质，这样容易确保相关结构的稳定性。同时，防滑凸筋7与面罩本体1以相同材质一体成型，暖鼻部密封环2也同样为弹性材质，且与面罩本体1之间可以是粘接或超声波焊接或一体成型。
如图13所示，在本发明的其它再选实施例中，加热部件43也可以设计成通电即发热且具有储液功能的电热容器24，该电热容器24具有向上敞口的储液腔241，该储液腔241的底壁上凸设有柱状通气孔242，当将该电热容器24替换上述实例中的电热片时，可以将柱状通气孔242的下端开口与暖鼻罩4中底盖4b的进气口421连通，并将柱状通气孔242的上端开口与暖鼻罩4中仿鼻形罩体4a底壁上的出气口422连通，这样一来，就不必在暖鼻罩4的底盖4b内壁上设置自进气口421向仿鼻形罩体4a延伸的环形凸台了，而且加注水溶液或药液时，只需通过进气口421和柱状通气孔242向储液腔241内注入即可。同时，电热容器24与上述实施例中电缆9的电连接方式可以参照电热片的连接方式来设计。
此外，在本发明的功能扩展中，还可以考虑在暖鼻罩内加入紫外线、红外线等灭菌装置和/或超声波雾化器等。
