Use method of clamping head capable of improving breathability of plane mask

Abstract

A use method of the clamping head capable of improving the air permeability of the plane mask comprises the following steps: step 1, preparation work, specifically, 1, designing a liner block mold, specifically, selecting a paper sheet cutting machine capable of conducting stamping cutting on paperboard with the thickness larger than 0.3 mm, conducting paper sheet cutting mold design and machining according to the figure 1 and the figure 2 respectively; (2) gasket block stamping: according to the process requirements, performing one-time stamping forming on card paper with the thickness of about 0.3 mm to form the gasket block; 3) disinfection and sterilization: carrying out disinfection and sterilization on the processed liner block by using ultraviolet rays; step 2, clamping head forming: 1) forming the clamping head hung on the mask for use: a pad block is taken, and the pad head is folded along a second crease line; the inner layer of the planar mask faces the liner body, and the long edge, with the metal strip, of the planar mask is placed in a groove formed after the liner head is folded; the gasket head is positioned in the middle of the long edge of the metal strip; the pad main body is rolled up in the reverse direction of the pad head to form a semi-cylindrical shape. The effective inspiration area of the mask can be effectively expanded.

Description

technical field [0001] The invention relates to the field of epidemic prevention equipment, in particular to a method for using a clamping head capable of improving the air permeability of a flat mask. Background technique [0002] During the epidemic, wearing masks that meet the medical standards of YY 0469-2011 "Medical Surgical Masks" can reduce the risk of infection with the new coronavirus. [0003] Medical surgical masks can not only prevent contact with virus carriers from spraying droplets, reduce the volume and spray speed of droplets, but also block virus-containing droplet nuclei and prevent wearers from inhaling them. During the period when the new crown epidemic is not over, people will be required to wear medical surgical masks for daily travel. [0004] However, when wearing a mask to exercise or engage in strenuous work, people's metabolism and lung capacity will increase, and the demand for oxygen will also increase. When the wearer of the mask inhales vio...

Problems solved by technology

Although this technology can form a certain distance between the front of the nose and the mask, the main body of the liner itself is airtight. Even if the main body of the liner is provided with a plurality of air holes, the ventilation area of ​​the mask is still greatly reduced, and the improvement of the ventilation effect is not ideal. , and this technology "when wearing a mask, by clipping the ends of the left and right side ear strips into the folds inside the mask... the mask liner of the present utility model is easily fixed on the inner surface of the mask"; the left and right side ear strips If it does not have a certain hardness, the main body of the liner cannot be fixed. If it has a certain hardness, the edges on both sides of the mask will not fit well with the face and there will be gaps, and the outside air will be filtered by the mask without being filtered by the mask. user inhalation defect

[0007] The existing public technology (authorized announcement number: CN207948981U) "a mask with increased internal filter area" increases the filter area by pleating the filter layer. Although this method can increase the filter area of ​​the mask, reduce breathing resistance and improve ventilation However, it also increases the difficulty of production, increases the production cost, and increases the thickness of the mask, and the user cannot guarantee that the pleated filter layer will not be squeezed and overlapped, and the pleated filter layer will overlap after being squeezed. , the function of reducing breathing resistance and improving air permeability not only cannot be realized, but may also increase breathing resistance and reduce air permeability
