本公开包含申请日为2020年03月16日、中国专利申请的申请号为“202010180258.X”相关的主题，通过引用将该在先专利申请的全部内容并入本申请中。
技术领域
本公开属于防护装置技术领域，涉及一种加热过滤式面罩及其使用方法。
背景技术
随着流感病毒或各种新型病毒等致病源的大范围流行，佩戴口罩成为大部分人群的首选。目前可以有效阻挡致病源的防护器件包括各种类型的防护口罩，包括：一次性医用防护口罩以及N95口罩等等。
然而，在寒冷的地方，特别是室外，戴口罩时呼出的水蒸气在口罩上凝结成冷水、甚至冻结成冰，堵塞气孔，冰冷和呼吸不畅让佩戴者很不舒服。更严重的是凝结的水破坏了医用防护口罩里的静电荷，降低了医用防护口罩对于致病源的吸附作用，同时有研究表明，有些新型病毒在低温下存活的时间更长。在低温场景下，医用防护口罩对于耐低温致病源的吸附效果变差。
对于携带病毒的病人而言，呼出的病毒在口罩里富集，形成浓度更大的病毒源，随着呼吸过程的持续病毒再次进入人体，吸入的冷空气更有助于病毒的感染，加重病人的病情，或延缓康复时间。对于健康人而言，口罩表面病毒富集，医用防护口罩里静电荷降低，病毒更容易进入人体，吸入的冷空气加大了病毒感染几率，冷空气的吸入除了不舒服外，冷却降低呼吸道及肺部温度，为病毒感染提供条件。另外，用过的口罩如果处理不当，会成为更加严重的污染源。
而现有技术中还没有一种能够有效解决上述技术问题的防护用具结构，因此，基于上述技术问题，亟需研发一种新型面罩结构，提升舒适度、 有效灭杀病毒并做好后续处理。

为使本公开的目的、技术方案和优点更加清楚明白，以下结合具体实施例，并参照附图，对本公开进一步详细说明。
参见图1至图5所示；
实施例一：
该实施例一主要介绍了加热过滤式面罩的具体结构。
本公开的加热过滤式面罩，该面罩包括：面罩本体1以及呼吸筒2。
面罩本体1具有弧度，弧度的内侧形成容置腔体。面罩本体1具有弧度的一侧呈开放结构，上述容置腔体在佩戴时可以作为呼吸腔。在一实施例中，面罩本体上设置有用于使用者佩戴的佩戴件，例如图1所示例的系带结构101。
呼吸筒2设置于面罩本体1表面，在图1中以呼吸筒2设置于面罩本体1的前端进行示例。
呼吸筒2内集成有面料结构4和加热结构3。
呼吸筒2为分体式结构，其包括与面罩本体1固连的第一筒体201、以及与第一筒体201装配固定的第二筒体202。
第一筒体201内嵌装有面料结构4、第二筒体202内嵌装有加热结构3；或第一筒体201内嵌装有加热结构3、第二筒体202内嵌装有医用口罩的面料结构4。
加热结构3具有加热体301、以及固定于加热体301表面的传热透气体。
传热透气体的表面积大于加热体301的表面积。
加热体301内置或外置控制电路，且加热体301通过控制电路控制加热温度处于预设范围，针对特定病毒，预设范围优选为20℃至60℃。在他实施例中，可以针对不同的病毒类型变化上述温度范围，同时温度不能过高，以保证人体佩戴的舒适度。
加热体301的控制电路电性连接有电源线303，且该电源线303延伸 至外部。
电源线303的输入端与外部供电设备电性连接以通过外部供电设备为加热体301供电，并使得加热结构3中的加热体301将电能转化为热能。
具体的，本实施例公开了一种能够实时加热的加热过滤式面罩，该面罩的面罩主体1具有弧度，弧度的内侧形成容置腔体，另一侧连通有呼吸筒2，将其佩戴后呼气和吸气都是通过呼吸筒2实现气流交换。同时，在呼吸筒2内集成了面料结构4和加热结构3，其中的面料结构4可以选用医用口罩面料，例如无纺布、聚丙烯熔喷无纺布，透气性较好。而加热结构3也嵌装于呼吸筒2内，其能够实时加热面料结构4，既能够保证舒适的佩戴温度，还可以实现杀菌消毒作用。更为具体的是，本实施例一种的呼吸筒2采用分体式结构，目的是为了方便更换内部配件，如上述的面料结构4和加热结构3，而面料结构4和加热结构3原则上并不局限于必须安装在哪个筒体内。同时，加热结构3由加热体301和传热透气体组成，为了确保传热效果和传热面积，能够有效地将热量传递给面料结构4，该传热透气体的面积需要大于加热体301，而且一般根据筒体的结构而定。同时，为了实现佩戴和消毒，加热体301的加热温度范围在20℃至60℃为最佳。
优选的，本实施例中面罩本体1采用硅胶材质。
面罩本体1的前侧一体成型有第一筒体201，且第一筒体201内部为中空结构，第一筒体201内的中空结构被配置为第一腔室。第一筒体201例如为圆筒结构或者其他截面形状的筒状结构。
第二筒体202与第一筒体201连接，且第二筒体202内部为中空结构，第二筒体202内的中空结构被配置为第二腔室。第一腔室和第二腔室连通。连接方式例如为螺纹连接。
示例性的，第一腔室内嵌装有面料结构4；第二腔室内嵌装有加热结构3。
第一筒体201朝向面罩本体1一端形成有第一呼吸口。第二筒体202远离第一筒体201一端形成有第二呼吸口。
第一呼吸口和第二呼吸口同轴布置，且第一呼吸口和第二呼吸口通过第一腔室和第二腔室连通以实现呼吸。
另外，上述的第一呼吸口和第二呼吸口整体呈轮状镂空结构，且第一呼吸口和第二呼吸口沿其周向间隔布置有多条间隔板20101，间隔板20101沿径向延伸。第一呼吸口和第二呼吸口均通过多条间隔板20101形成上述轮状镂空结构。相邻间隔板20101之间的空间为呼吸孔20102。
该处详细介绍了面罩本体1和呼吸筒2的结构，其中，考虑到佩戴的舒适度，面罩本体1选用硅胶材料为最佳，而呼吸筒2为了能够便于后期维护和更换内部配件，呼吸筒2采用分体式结构，第一筒体201和第二筒体202均为圆筒结构，且内部中空，分别将面料结构4和加热结构3嵌入后，以螺纹紧固的方式将两者组合为一体，此时，面料结构4和加热结构3相互靠近，而且为了保证透气效果好，呼吸口处设计为整体镂空的结构，提高透气性。
优选的，本实施例中面料结构4的材质为医用面料。
面料结构4的截面形状和尺寸与第一呼吸口匹配并覆盖于第一呼吸口的内侧面。
面料结构4配设有O型密封压圈20103。
面料结构4嵌入第一腔室时，通过O型密封压圈20103紧固于第一腔室内、并与第一呼吸口贴靠。
面料结构4的材料取材方便，将其裁剪到合适尺寸后，直接嵌入对应的筒体内，然后利用O型压圈20103压持住边缘，这样就不会再使用时出现脱落或移位，为O型压圈20103和筒体的内壁以过盈配合的方式装配，能够提高结构稳定性。
其中，上述的加热结构3包括加热体301以及位于加热体301表面的两片传热透气体，两片传热透气体将加热体301夹于中间。
加热体301为碳纤维布加热片，且加热体301的尺寸为40mm×40mm，或者为其他尺寸，例如35mm×35mm～45mm×45mm之间。
加热体的材料为外表面防水绝缘的发热材料；传热透气体的材料包括具有网孔的导热材料，网孔被配置为透气孔。
在一实施例中，传热透气体选用铜网302。
在一实施例中，传热透气体采用目数为30至100目的铜网302。
加热体301内部集成有防水绝缘的碳纤维发热布，该碳纤维发热布通 过电源线303与外部供电设备电性连接以将电能转化为热能。
传热透气体的表面被配置为加热体301的传热表面。
传热透气体的表面积至少与面料结构4的表面积匹配。
传热透气体的目孔被配置为透气孔。
加热体301外表面包裹有绝缘层。
本公开的加热结构3包括一片加热体301和覆盖在加热片301两侧表面的传热透气体。其中，加热体301直接选用碳纤维布加热片，该碳纤维布加热片具有发热电路，同时发热电路电性连接有电源线303，电源线303向外延伸，并且预留输入端，为了方便使用，该输入端一般选用USB接口。另外，上述的传热透气体可以选用铜网302，而铜网302的规格详见上述，但是并不局限于上述规格，其可以根据加热面罩的尺寸适当调整。本实施例的传热透气体选用铜网302的目的是：铜网302是良好的导热体，并且在导热的同时具有一定的杀菌作用，另外，设计了目数为30至100目的铜网302能够保证透气，且铜网302的面积大于加热体301的面积能够透气面，由于加热体301是透气性较差的，因此，在加热体301的两侧覆盖两片铜网302后能够利用铜网302表面均匀开设的目孔完成气流的导通，增大呼吸面，提高舒适度。最后，这样设计还有一定的防水效果。
实施例二：
本公开公开的加热过滤式面罩的使用方法，该实施例二主要介绍了加热过滤式面罩(简称为面罩)的第一种使用方法，其主要包括以下步骤：
S101、首先将面料结构4和加热结构3对应嵌装于第一筒体201和第二筒体202内，并将第一筒体201和第二筒体202装配固定；
S102、佩戴医用口罩，然后将组装好的面罩佩戴于医用口罩的外部；
S103、将加热结构3的电源线303与外部供电设备连接，加热结构3通电后将电能转化为热能持续加热，热量通过加热结构3的铜网302传递至面料结构4、并进一步传递至医用口罩；
S104、佩戴后将医用口罩和面罩同时取下，并调节加热结构3的加热温度至56℃以上以对医用口罩和面罩进行加热消毒。
本实施例二采用加热面罩和医用口罩一起佩戴的方式，具体步骤如上所述，佩戴状态下，能够实时对医用口罩和面罩加热，让佩戴区域内始终 处于较为舒适的温度范围，避免了医用口罩静电荷的破坏，提高病毒吸附性。而在非佩戴状态下，面罩内加热结构3升温至较高温度后能够对面罩和医用口罩进行消毒，实现循环利用。
实施例三：
本公开公开的加热过滤式面罩的使用方法，该实施例三具体介绍了加热过滤式面罩(简称为面罩)的第二种使用方法，其主要包括以下步骤：
S201、首先将面料结构4和加热结构3对应嵌装于第一筒体201和第二筒体202内，并将第一筒体201和第二筒体202装配固定；
S202、直接佩戴面罩；
S203、将加热结构3的电源线303与外部购电设备连接，加热结构3通电后将电能转化为热能持续加热，热量通过加热结构3的铜网302传递至面料结构4；
S204、佩戴后将面罩取下，并调节加热结构3的加热温度至56℃以上对面罩进行加热消毒。
本实施例三采用了单独使用加热面罩的佩戴方式，同理，其在加热结构3的持续加热下，能够确保佩戴区域始终处于较为舒适的温度范围，并在佩戴后能够利用加热结构对面罩进行杀菌消毒。
加热过滤式面罩可以单独佩戴，也可以与防护口罩(例如医用口罩)一起佩戴，并在加热过滤式面罩集成了面料结构和加热结构，通过加热结构持续加热，实现对佩戴医用口罩或单纯佩戴面罩的实时加热，既保证了佩戴温度适宜，还可以避免呼出水蒸气凝结破坏医用口罩内的静电荷，提高对病毒吸附能力。
本公开的加热面罩对于携带病毒的病人而言，呼出的病毒在加热面罩和口罩里富集，但高温降低了病毒的活性，缩短病毒生存时间甚至灭活；而吸入的热空气不利于病毒的生存。因此，该加热面罩不但可以防止病人病毒扩散，还可以对病人进行辅助治疗，加快康复。对于健康人而言，电热口罩外表面温度高，病毒生存几率小，不利于病毒的感染，阻止病毒性感冒的发生和流行。
综上所述，本公开提供了一种加热过滤式面罩及其使用方法，基于呼吸筒内加热结构的设置，提升了加热过滤式面罩的容置腔室的温度，能够 实现对于口罩外部的不耐高温致病源的抑制以及对于口罩内部的致病源的杀灭或缩短生存时间，在利于低温致病源的场景下实现有效防护；该加热过滤式面罩可以直接佩戴使用，或者在使用者佩戴了口罩的情况下与口罩配合，使得加热过滤式面罩位于口罩的外部，在使用完成后可以对佩戴的加热过滤式面罩，或者佩戴的加热过滤式面罩和口罩进行高温处理，能够实现加热过滤式面罩的循环使用。
