Description

口罩
本申请要求于2022年4月12日在中国专利局提交的、申请号为202220837522.7的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请属于卫生用品技术领域，更具体地说，是涉及口罩。
 背景技术
口罩是一种卫生用品，一般佩戴在口鼻部位用于过滤进入口鼻的空气，以达到阻挡有害的气体、气味、飞沫、病毒等物质的作用，以纱布或纸等材料做成。口罩对进入肺部的空气有一定的过滤作用，在呼吸道传染病流行时，在粉尘等污染的环境中作业时，戴口罩具有非常好的过滤净化空气作用。
由于人体呼出的气体中含有大量的水汽，在长时间使用口罩后，水汽容易凝结在口罩内侧，使口罩内侧容易粘附在皮肤上，使用者容易产生黏肤感、闷湿感，影响了口罩的使用体验。
 技术问题
本申请实施例的目的在于提供一种口罩，以解决现有技术中存在的口罩内侧易粘附在皮肤上，并影响口罩使用体验的技术问题。
 技术解决方案
为实现上述目的，本申请采用的技术方案是：
提供一种口罩，包括内面料层和连接于所述内面料层的外侧的外面料层，所述内面料层的内侧面用于与使用者接触且形成有多个彼此间隔的凹坑。
作为上述技术方案的进一步改进：
可选的，所述凹坑凸出于所述内面料层的外侧面。
可选的，所述内面料层包括基面部和形成所述凹坑的凹面部，所述凹坑的深度大于所述基面部的厚度。
可选的，多个所述凹坑形成多组凹坑组，每一组所述凹坑组中包括多个沿直线间隔布置的凹坑，各所述凹坑组平行间隔布置。
可选的，所述凹坑为椭圆形凹坑。
可选的，所述内面料层和外面料层之间还设有中面料层。
可选的，所述内面料层和外面料层为纺粘无纺布面料层，所述中面料层为熔喷无纺布面料层。
可选的，所述口罩包括口罩基体、可折叠连接于所述口罩基体的上折叠部、可折叠连接于所述口罩基体的且位于所述上折叠部的下方的下折叠部，所述口罩基体、上折叠部和下折叠部均设有所述内面料层。
可选的，所述口罩基体、上折叠部和下折叠部形成为一体结构。
可选的，所述口罩还包括用于使用者佩戴的系带，所述系带连接于所述口罩基体上。
本申请提供的口罩的有益效果在于：
本申请提供一种口罩，包括内面料层和连接于内面料层的外侧的外面料层，内面料层的内侧面用于与使用者接触且形成有多个彼此间隔的凹坑。其中，内面料层是指使用时与使用者皮肤接触的面料层；外面料层是指使用时背离使用者皮肤的面料层；内面料层的内侧面在使用时能够与使用者皮肤接触，内面料层的外侧面在使用时不与使用者皮肤接触。内面料层的内侧面形成有多个彼此间隔的凹坑，从而减小了内面料层的内侧面与使用者皮肤接触的面积，减轻了内面料层对使用者皮肤的黏肤感，提升了该口罩的使用体验。内面料层的内侧面的凹坑还起到了增大过滤面积的作用。在投影面积相同的条件下，凹坑的表面积相比于普通平顺面料的表面积更大，因此，具有凹坑的内面料层具有更大的过滤面积，单位时间内能够过滤更多的空气，具有更好的透气性，还能减轻口罩长时间使用产生的闷湿感，提升了该口罩的使用体验。
相比于传统的口罩，本申请的口罩具有减少与使用者皮肤的接触面积，减轻对使用者皮肤的黏肤感；具有更好的透气性，还能减轻口罩长时间使用产生的闷湿感。相比于传统的口罩，本申请的口罩具有更好的使用体验。
本申请的口罩还具有以下优点：
（1）本申请的口罩相比于传统的口罩，能够降低约20%的口罩面料的使用，从而减少口罩面料的消耗，减少口罩面料生产工艺产生的废气废水，具有节能环保、生产成本低的优点。
（2）本申请的口罩在长时间使用后，即使内面料层粘附有使用者的口水，但由于内面料层的凹坑降低了与使用者皮肤的接触面积，因此，能减少口水粘附到使用者皮肤上，降低口罩佩戴时的湿黏感。
（3）由于减少了内面料层与皮肤的接触面积，因此能够减少内面料层与皮肤的摩擦面积，从而减少内面料层因摩擦产生的布料毛刺，使内面料层柔顺舒适，避免使用者佩戴后产生痒感。

由于人体呼出的气体中含有大量的水汽，在长时间使用口罩后，水汽容易凝结在口罩内侧，使口罩内侧容易粘附在皮肤上，使用者容易产生黏肤感、闷湿感，影响了口罩的使用体验。
如图1至图4所示，本实施例提供一种口罩，包括内面料层1和连接于内面料层1的外侧的外面料层2，内面料层1的内侧面用于与使用者接触且形成有多个彼此间隔的凹坑3。
其中，内面料层1是指使用时与使用者皮肤接触的面料层；外面料层2是指使用时背离使用者皮肤的面料层；内面料层1的内侧面在使用时能够与使用者皮肤接触，内面料层1的外侧面在使用时不与使用者皮肤接触。
内面料层1的内侧面形成有多个彼此间隔的凹坑3，从而减小了内面料层1的内侧面与使用者皮肤接触的面积，减轻了内面料层1对使用者皮肤的黏肤感，提升了该口罩的使用体验。
内面料层1的内侧面的凹坑3还起到了增大过滤面积的作用。在投影面积相同的条件下，凹坑3的表面积相比于普通平顺面料的表面积更大，因此，具有凹坑3的内面料层1具有更大的过滤面积，单位时间内能够过滤更多的空气，具有更好的透气性，还能减轻口罩长时间使用产生的闷湿感，提升了该口罩的使用体验。
相比于传统的口罩，本申请的口罩具有减少与使用者皮肤的接触面积，减轻对使用者皮肤的黏肤感；具有更好的透气性，还能减轻口罩长时间使用产生的闷湿感。相比于传统的口罩，本申请的口罩具有更好的使用体验。
本申请的口罩还具有以下优点：
（1）本申请的口罩相比于传统的口罩，能够降低约20%的口罩面料的使用，从而减少口罩面料的消耗，减少口罩面料生产工艺产生的废气废水，具有节能环保、生产成本低的优点。
（2）本申请的口罩在长时间使用后，即使内面料层1粘附有使用者的口水，但由于内面料层1的凹坑3降低了与使用者皮肤的接触面积，因此，能减少口水粘附到使用者皮肤上，降低口罩佩戴时的湿黏感。
（3）由于减少了内面料层1与皮肤的接触面积，因此能够减少内面料层1与皮肤的摩擦面积，从而减少内面料层1因摩擦产生的布料毛刺，使内面料层1柔顺舒适，避免使用者佩戴后产生痒感。
本实施例提供的内面料层1适用于普通纱布口罩、工业防尘口罩、家用防尘口罩、医用口罩、平面型口罩、折叠型口罩、碗型口罩等。
如图4所示，在一个实施例中，凹坑3凸出于内面料层1的外侧面，即在内面料层1的外侧面形成与凹坑3对应的凸起，内面料层1的厚度均匀，防止内面料层1形成的凹坑3处厚度减小，而降低内面料层1的过滤作用。还能确保凹坑3的表面与使用者的皮肤之间具有足够的距离，防止内面料层1湿软后，凹坑3的表面粘附到使用者的皮肤上。在其他实施例中，也可根据内面料层1不同的生产工艺，使内面料层1的外侧面不形成凸起。
如图4所示，在一个实施例中，内面料层1包括基面部11和形成凹坑3的凹面部12，凹坑3的深度h 1大于基面部11的厚度h 2。
其中，基面部11是指内面料层1上与使用者皮肤接触的部分，凹面部12是指内面料层1上形成凹坑3不与使用者皮肤接触的部分。凹坑3的深度h 1大于基面部11的厚度h 2，以使内面料层1的外侧面能够形成与凹坑3对应的凸起，确保凹面部12的表面与使用者的皮肤之间具有足够的距离，防止凹面部12湿软后，凹面部12的表面粘附到使用者的皮肤上。
如图4所示，在一个实施例中，凹面部12的厚度h 3大于基面部11的厚度h 2，不仅有助于保持凹坑3的凹坑结构，防止凹坑3容易被压平，还有助于增加空气通过凹面部12的过滤距离增加，从而提高凹面部12的过滤效果。
应当注意的是，凹面部12的厚度大于基面部11的厚度只是本申请的一种优选实施例，在其他实施例中，凹面部12的厚度小于或等于基面部11的厚度也应落入本申请的保护范围。
根据不同生产工艺，可控制凹面部12的厚度大于基面部11的厚度。例如使用热压工艺时，通过上模和下模的热力压合，使内面料层1形成基面部11和凹面部12。基面部11的厚度取决于形成基面部11的上模和下模的间隙，凹面部12的厚度取决于形成凹面部12的上模和下模的间隙。因此，只需控制形成凹面部12的上模和下模的间隙大于形成基面部11的上模和下模的间隙，即可生产出凹面部12的厚度大于基面部11的厚度的内面料层1。
如图1和图3所示，在一个实施例中，多个凹坑3形成多组凹坑组，每一组凹坑组中包括多个沿直线间隔布置的凹坑3，各凹坑组平行间隔布置。
多个凹坑3沿直线间隔布置能够有效利用内面料层1的内侧面面积，增加内侧面上凹坑3的布置密度，也有利于内面料层1更加贴合面部曲面的变化，防止内面料层1与使用者皮肤之间产生较大的间隙或空腔。
在其他实施例中，多个凹坑3还可以沿其他图案或形状的纹路彼此间隔排布，以提高口罩的美观性。
如图3所示，在一个实施例中，凹坑3为椭圆形凹坑。在其他实施例中，凹坑3还可以为其他几何形状的凹坑3，例如圆形凹坑、多边形凹坑等。
如图1、图2和图3所示，在一个实施例中，内面料层1和外面料层2之间还设有中面料层4。中面料层4有助于加强内面料层1和外面料层2的过滤作用，从而提高本申请的口罩的过滤净化性能。
在一个实施例中，内面料层1和外面料层2为纺粘无纺布面料层，中面料层4为熔喷无纺布面料层。在其他实施例中，内面料层1、外面料层2和中面料层4还可以为纱布、活性炭布、滤纸等。
纺粘无纺布是将涤纶和丙纶聚合物挤出、拉伸，形成连续长丝后，长丝铺设成网，纤网再经过自身粘合、热粘合、化学粘合或机械加固方法，使纤网变成无纺布，具有耐高/低温性能好、耐老化、抗紫外线、延伸率高、稳定性和透气性好、耐腐蚀、隔音、防蛀、无毒等优点。
熔喷无纺布被称为口罩的“心脏”，起到主要的过滤、吸附微型颗粒的作用。熔喷无纺布是将聚丙烯熔融挤出，形成聚丙烯纤维，聚丙烯纤维随机交织堆叠，形成聚丙烯纤维网，并依靠聚丙烯纤维的余热互相熔融黏合，形成熔喷无纺布。内面料层1和外面料层2的纺粘无纺布的纤维直径较粗，在20微米左右;中面料层4的熔喷无纺布的纤维直径较细，只有2微米左右。熔喷无纺布相比纺粘无纺布具有更小的颗粒透过孔径，更好的过滤性，是生产口罩的核心原料。
如图5至图10所示，在一个实施例中，口罩包括口罩基体5、可折叠连接于口罩基体5的上折叠部6、可折叠连接于口罩基体5的且位于上折叠部6的下方的下折叠部7，口罩基体5、上折叠部6和下折叠部7均设有内面料层1。
使用时，分别将上折叠部6和下折叠部7展开，口罩基体5、上折叠部6和下折叠部7形成能够与面部适配的曲面结构。通过内面料层1减轻口罩基体5、上折叠部6和下折叠部7对使用者产生的黏肤感和闷湿感。
在一个实施例中，上折叠部6上还设有鼻梁筋。使用时，鼻梁筋与使用者鼻梁部位对应。鼻梁筋用于使口罩完全贴合鼻梁及面部，隔绝内外部，避免外部飞沫与空气中的病菌通过口罩缝隙进入鼻腔和口腔，同时也能够防止佩戴人的飞沫及病菌往外传播。鼻梁筋由镀锌铁丝制成，部分镀锌铁丝外侧还包裹有PVC或PP材料。
如图10所示，在一个实施例中，口罩基体5、上折叠部6和下折叠部7形成为一体结构。口罩基体5、上折叠部6和下折叠部7通过超声波焊接或热压焊接形成为一体结构，使口罩具有结实可靠、使用方便、便于批量生产的优点。在其他实施例中，口罩基体5、上折叠部6和下折叠部7也可通过粘结带、系绳、按扣等实现彼此可拆卸连接。
如图5、图6和图10所示，在一个实施例中，口罩还包括用于使用者佩戴的系带8，系带8连接于口罩基体5上。
系带8通过超声波焊接或热压焊接固定在口罩基体5上。系带8用于挂在使用者双耳或箍套在使用者的头部，以将口罩固定并遮盖在使用者的口鼻部位。系带8的材质有氨纶、涤纶、硅胶等。在其他实施例中，系带8还可以是系绳、系片等。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
