一种口罩a mask

技术领域technical field

本发明属于口罩生产技术领域，涉及一种基于强化过滤和人体工学的新型口罩。The invention belongs to the technical field of mask production, and relates to a novel mask based on enhanced filtration and ergonomics.

背景技术Background technique

口罩是一种卫生用品，是戴在口鼻部位用来过滤进入口鼻的空气，从而拦截飞沫、病毒、有害气体和粉尘等。A mask is a sanitary product that is worn on the mouth and nose to filter the air entering the mouth and nose, thereby intercepting droplets, viruses, harmful gases and dust.

现有口罩从总体形状上看有杯型、平板型等，从细部看有褶皱型和无褶皱型。褶皱型口罩为立体过滤，过滤面积大，且过滤面刚性好，不易贴着脸部，保证有效过滤面积。无褶皱型口罩为平面过滤，过滤面积小，且易贴着脸部而缩小有效过滤面积。现有杯型口罩一般都为无褶皱型。平板型口罩有褶皱型和无褶皱型。然而，现有的有褶皱型口罩使用时往往被拉平，很大部分被拉至下颚甚至更低，覆在颈部而失去过滤作用。有效过滤面积的缩小，必将增大过滤阻力而影响呼吸。另外，传统的口罩呼出的湿气难以排出口罩，使口罩受潮，过滤阻力进一步增大，佩戴时间越长，呼吸阻力越大，且病菌易于存活。再者，传统口罩未充分考虑人体工学，口罩四周特别是鼻梁两侧的密封性差，容易产生漏气，使吸气短路，影响口罩的防护性能，而且与此同时，呼出的湿气会经过鼻梁两侧的通道向上排出，经过眼镜，水汽冷凝在镜片上，影响佩戴眼镜者视线。Existing masks are cup-shaped, flat-shaped, etc. in terms of overall shape, and wrinkled and wrinkled-free in detail. The pleated mask is a three-dimensional filter, with a large filtering area and good rigidity of the filtering surface, which is not easy to stick to the face, ensuring an effective filtering area. The non-fold mask is a flat filter with a small filtering area, and it is easy to stick to the face to reduce the effective filtering area. Existing cup-shaped masks are generally wrinkle-free. Flat masks are available in pleated and unwrinkled types. However, the existing pleated masks are often flattened when used, and a large part is pulled to the lower jaw or even lower, covering the neck and losing the filtering effect. The reduction of the effective filtration area will inevitably increase the filtration resistance and affect breathing. In addition, the moisture exhaled from the traditional mask is difficult to be discharged from the mask, which makes the mask damp, and the filtration resistance further increases. The longer the wearing time, the greater the breathing resistance, and the bacteria are easy to survive. Furthermore, traditional masks do not fully consider ergonomics. The sealing around the mask, especially on both sides of the bridge of the nose, is poor, which is prone to air leakage, short-circuiting the inhalation, and affecting the protective performance of the mask. At the same time, the exhaled moisture will pass through the bridge of the nose. The channels on both sides are discharged upwards, passing through the glasses, and the water vapor condenses on the lenses, which affects the vision of the wearer.

具体实施方式Detailed ways

为使本新型口罩的结构优点能更加清晰的表达，下面结合附图对该新型口罩进一步说明。In order to make the structural advantages of the novel mask more clearly expressed, the novel mask is further described below in conjunction with the accompanying drawings.

如图1和图2所示为横向褶皱型口罩的正面和沿对称轴的纵剖面图。如图3和4所示为竖向褶皱型口罩的正面和沿对称轴的纵剖面图。所述的一种新型口罩包括罩体2和系带1。所述罩体2由多层单向滤布制成的褶皱面4、平边3、弹性软衬垫5、限拉弹性线7和鼻梁条6组成。As shown in Figure 1 and Figure 2, the front face and longitudinal section along the axis of symmetry of the transversely pleated mask are shown. Figures 3 and 4 show the front face and longitudinal section along the axis of symmetry of the vertically pleated mask. The new type of mask includes a cover body 2 and a strap 1 . The cover body 2 is composed of a pleated surface 4 made of multi-layer unidirectional filter cloth, a flat edge 3 , an elastic soft pad 5 , a tension-limiting elastic thread 7 and a nose bridge strip 6 .

罩体2的主体为褶皱面4，褶皱面4四周为没有皱褶的平边3，能紧密贴合脸部皮肤，保证密封性。其中上边沿平边3上设置有鼻梁条6。鼻梁条6以罩体2的对称轴为中心对称设置。The main body of the cover body 2 is a wrinkled surface 4, and the surrounding of the wrinkled surface 4 is a flat edge 3 without wrinkle, which can closely fit the skin of the face and ensure airtightness. The upper edge flat edge 3 is provided with a nose bridge strip 6 . The nose bridge strip 6 is symmetrically arranged with the axis of symmetry of the cover body 2 as the center.

褶皱面4的两边与平边3光滑过渡固定，褶间有一定间隙，褶呈弧状突出，增大了过滤面积，减小呼吸阻力。口罩褶皱面4上的褶数至少为5，褶皱面4拉开时，褶高为5～15mm，褶皱的高宽比为0.5～1.5。褶皱面4上的褶皱可以是横向的也可是竖向的，形成立体过滤，以增大过滤面积，减小吸气阻力。The two sides of the pleated surface 4 and the flat edge 3 are smoothly transitioned and fixed, there is a certain gap between the pleats, and the pleats are protruding in an arc shape, which increases the filtering area and reduces the breathing resistance. The number of pleats on the pleated surface 4 of the mask is at least 5. When the pleated surface 4 is opened, the pleat height is 5-15mm, and the height-width ratio of the pleats is 0.5-1.5. The pleats on the pleated surface 4 can be horizontal or vertical to form a three-dimensional filter, so as to increase the filter area and reduce the suction resistance.

限拉弹性线7设置在褶皱面4上，并且贯穿于褶皱面4上的所有褶皱，使各褶皱均与限拉弹性线7连接，限拉弹性线7具有一定的弹性，即不影响褶皱面的褶皱拉开，又由限拉弹性线7限制各褶皱的拉开程度，以免褶皱面4被拉至下颚或更低的位置而覆在颈部失去过滤作用。较佳地设置在褶皱面4的对称轴上，限拉弹性线7的两端固定在上、下或左、右相对的两平边3上。The stretch-limiting elastic thread 7 is arranged on the pleated surface 4 and runs through all the folds on the pleated surface 4, so that each pleat is connected with the stretch-limiting elastic thread 7, and the tension-limiting elastic thread 7 has a certain elasticity, that is, it does not affect the pleated surface. The folds are pulled apart, and the pulling degree of each fold is limited by the stretch-limiting elastic thread 7, so as to prevent the folded surface 4 from being pulled to the lower jaw or lower and covering the neck to lose its filtering effect. It is preferably arranged on the symmetry axis of the pleated surface 4, and the two ends of the tension-limiting elastic wire 7 are fixed on the upper, lower or left and right opposite flat sides 3.

口罩的上边沿平边3内侧设有弹性软衬垫5。较佳地，弹性软衬垫5为对称设置的两个，两个弹性软衬垫5分别位于鼻梁条6的两端。弹性软衬垫5由柔软而富有弹性的布料制成，具有强化口罩密封的效果，同时确保佩戴的舒适性。口罩佩戴后，弹性软衬垫5对称位于鼻翼上方的鼻梁条6两侧，防止漏气且符合人体工学。The upper edge of the mask is provided with an elastic soft pad 5 on the inner side of the flat edge 3 . Preferably, two elastic soft pads 5 are arranged symmetrically, and the two elastic soft pads 5 are located at two ends of the nose bridge strip 6 respectively. The elastic soft pad 5 is made of soft and elastic cloth, which has the effect of strengthening the sealing of the mask, while ensuring the comfort of wearing. After the mask is worn, the elastic soft pads 5 are symmetrically located on both sides of the bridge strip 6 above the nose alar to prevent air leakage and conform to ergonomics.

弹性软衬垫5的宽度为5～10mm。The width of the elastic soft pad 5 is 5-10 mm.

口罩打开使用时呈碗形，形成立体呼吸，且便于折叠包装。口罩可折叠成平面，以减小体积，易于储运。When the mask is opened and used, it is bowl-shaped, forming three-dimensional breathing, and it is easy to fold and pack. The mask can be folded into a flat surface to reduce the volume and facilitate storage and transportation.

单向滤布是单面经过拉绒后表面呈现绒毛状的布料，口罩外侧有绒毛，内侧没有绒毛。吸气时绒毛闭合，起过滤作用。呼气时张开，没有过滤作用，此时呼气阻力小，同时呼出的水汽可以及时排出，减少口罩受潮，使口罩保持低过滤阻力状态，且抑制病菌的存活。另外，由于水汽容易通过单向滤布呼出，且鼻梁两侧的密封性好，可以很好地防止水汽从鼻梁两侧呼出而避免眼镜起雾。One-way filter cloth is a cloth with fluffy surface after brushing on one side. There is fluff on the outside of the mask and no fluff on the inside. The villi close when inhaling and act as a filter. Open when exhaling, there is no filtering effect, the exhalation resistance is small at this time, and the exhaled water vapor can be discharged in time, reducing the dampness of the mask, keeping the mask in a state of low filtering resistance, and inhibiting the survival of germs. In addition, because the water vapor is easily exhaled through the one-way filter cloth, and the sealing on both sides of the bridge of the nose is good, it can well prevent the water vapor from being exhaled from both sides of the bridge of the nose and avoid fogging of the glasses.
