具体实施方式
本发明通过实施例结合附图加以说明
实施例1
参见图1图2和图3，本发明包括有口罩本体1、拉紧带2、口呼吸部3、鼻呼吸部4、口鼻呼吸隔离部5a。本实施例中口鼻 呼吸隔离部5a由片状体结构部构成，其构成方式是将裁制的片状体材料段，在口罩本体1内里侧将其设置的边缘部与口罩本体1相应位置水平向相连接，余部成自由松散状，形成了口罩片状体结构部，所述结构部设置在人体口鼻部之间上唇部位置处，口罩使用时在拉紧带2拉紧力作用下，所述结构部以人体上唇部为受力支撑贴附在皮肤表面同口罩本体1围设在人体面部对口鼻部形成了隔离，与此同时也使口罩内形成了相互隔离的口呼吸部3与鼻呼吸部4，使口鼻呼吸可以相互隔离进行，因此，所述片状体结构部构成了本实施例中的口鼻呼吸隔离部5a。虽然本实施例中拉紧带2与口鼻呼吸隔离部5a是分离设置的，但在具体实施时相互连接形成一体也是可以的。
实施例2
参见图4图5，本实施例与实施例1基本相同，所不同的是本实施例中口鼻呼吸隔离部5b由叠加体结构部造成，其构成方式是先将口罩本体材料设置成上下两段体，将上段体置外、下段体置内，在设定位置处形成局部叠加状再将上段体的下边缘部与下段体相连接，连接后的两段体构成了口罩本体1，叠加部分则形成了口罩的叠加体结构部。所述结构部设置在人体口鼻之间上唇部位置处，口罩使用时在拉紧带2拉紧力作用下，所述结构部以上唇部为受力支撑贴附在皮肤表面同口罩本体1围设在人体面部对口鼻部形成了隔离，与此同时也使口罩内形成了相互隔离的口呼吸部3与鼻呼吸部4，使口鼻呼吸可以相互隔离进行，因 此，所述叠加体结构部构成了本实施例中的口鼻呼吸隔离部5b。
在本实施例中拉紧带2与口罩呼吸隔离部5b是分离设置的，在具体实施时相互连接形成一体也是可以的。
实施例3
参见图6图7，本实施例与实施例1基本相同，所不同的是本实施例中口罩的口鼻呼吸隔离部5c由中空体结构部构成，其构成方式是将窄条状材料体在口罩本体1内里侧设定位置处将其两边缘部分别与口罩本体1水平向相连接，形成了两边封闭两端通透的中空体结构部，拉紧带2-2从其两端穿过，所述结构部设置在人体口鼻部之间上唇部位置处，口罩使用时在拉紧带2-2拉紧力作用下，所述结构部以上唇部为受力支撑贴附在皮肤表面同口罩本体1围设在人体面部对口鼻部形成了隔离，与此同时也使口罩内形成了相互隔离的口呼吸部3与鼻呼吸部4，使口罩内口鼻呼吸可以相互隔离进行，因此，所述中空体结构部构成了本实施例中的口鼻呼吸隔离部5c。虽然在本实施例中所述中空体结构部设置在口罩本体1内里侧，在具体实施时将所述结构部设置在口罩本体1的外侧面也是可以的。
实施例4
参见图8图9，本实施例与实施例1基本相同，所不同的是本实施例中口鼻呼吸隔离部5d由绳状体结构部构成，其构成方式是在口罩本体1设定位置处设置一对孔形开口6，将一段绳状体从中穿过挂置附着在口罩本体1外表面形成了绳状体结构部， 所述结构部设置在人体口鼻之间上唇部位置处，口罩使用时通过拉紧结构中的绳状体使结构部以上唇部为受力支撑同口罩本体1围设在人体面部对口鼻部形成了隔离，与此同时也使口罩内形成了相互隔离的口呼吸部3与鼻呼吸部4，使口鼻呼吸可以相互隔离进行，因此，所述绳状体结构部构成了本实施例中的口鼻呼吸隔离部5d。本实施例中在口罩本体设置的是孔状开口，在具体实施时设置成1字形开口、或设置成环绊或耳绊等可将绳状体定位的其他连接方式都是可以采用的，在具体实施时将绳状体改成带状体也是可以的。
实施例5
参见图10图11，本实施例与实施例1基本相同，所不同的是本实施例中口罩的口鼻隔离部5e是由金属质填充体结构部构成的，其构成方式是将一段可塑形的金属质直条形材料体设置填充在口罩本体面料夹层内形成填充体结构部，所述结构部设置在人体口鼻之间上唇部位置处，口罩使用时在拉紧带2拉紧力与金属质填充体塑形作用下，所述结构部以上唇部为受力支撑贴附在皮肤表面同口罩本体1围设在人体面部对口鼻部形成了隔离，与此同时也使口罩内形成了相互隔离的口呼吸部3与鼻呼吸部4，使口鼻呼吸可以隔离进行，因此，所述金属质填充体结构部在本实施例中构成了口罩的口鼻呼吸隔离部5e。虽然本实施例中口鼻呼吸隔离部5e采用的是直条形金属质填充体，但在具体实施时采用U形或V形或弧形或环形等金属质填充体也是可以的。
实施例6
参考图12图13，本实施例与实施例1基本相同，所不同的是口鼻呼吸隔离部5f，由非金属质填充体结构部构成，其构成方式是将一段可弹性变形的非金属质空心状直条形硅胶体，设置在口罩本体1面料夹层中形成填充体结构部，所述结构部设置在人体口鼻之间上唇部位置处，口罩使用时在拉紧带2拉紧力及硅胶体弹性力作用下，所述结构部以上唇部为受力支撑贴附在皮肤表面同口罩本体1围设在人体面部对口鼻部形成隔离，与此同时也使口罩内形成了相互隔离的口呼吸部3与鼻呼吸部4，使口鼻呼吸可以隔离进行。因此，所述非金属质填充体结构部构成了本实施例中的口鼻呼吸隔离部5f。虽然在本实施例中口鼻呼吸隔离部5f采用的是非金属质空心状直条形硅胶填充体，具体实施时采用U形或V形或弧形或环形等空心或非空心或其它适宜的非硅胶填充体也是可以的。
综上所述，在本发明中由于设置了口鼻呼吸隔离部，使口罩内口鼻呼吸可以相互隔离独立进行，使用者可避免呼出的气体再吸入，因此，有益于使用者呼吸健康特别是有益于需长时间使用口罩的医护工作者的呼吸健康。
本发明中的口呼吸部与鼻呼吸部可以独立设置使用。
