Cup-shaped hollow protective mask and preparation method

Abstract

The invention is applicable to the technical field of medical treatment, and provides a cup-shaped hollow protective mask and a preparation method. The mask comprises: a mask body forming a filter layer, a nose bridge strip fixedly connected to the upper portion of the mask body and used for forming a bent structure, and ear bands fixedly connected to the two ends of the mask body and used for being connected with the ears for wearing the mask body, wherein the mask body comprises an inner filter layer and an outer filter layer, the area of the inner filter layer is smaller than that of the outer filter layer, and the edges of the inner filter layer and the outer filter layer are hermetically connected to form a hollow structure. The technical design of the hollow structure is added between the inner filter layer and the outer filter layer in the mask body, and then a large amount of air can be stored in the hollow part of the inner filter layer and the outer filter layer; therefore, when a user inhales, the air in the hollow part can provide resistance buffering, and the problem that the health is affected due to the fact that inhaling is difficult and unsmooth because the resistance is too large and the air volume is insufficient when the user inhales can be solved and relieved through the mask body modified through the hollow technology.

Description

technical field [0001] The invention belongs to the field of medical technology, in particular to a cup-shaped hollow protective mask and a preparation method. Background technique [0002] For a long time, masks have been widely used for the prevention of colds, or for preventing the adsorption of dust. In addition, masks are also used to alleviate hay fever in spring when pollen is scattered. As we all know, masks are protective equipment, which is an indispensable protective equipment for workers in the source of infection and dusty environment. If the design is not good, the resistance will be too large, which will cause breathing difficulties and harm the health of users, let alone Conducive to the healthy development of the industry. For the existing cup-shaped masks, they all adopt a one-time molding design. The one-time molding product has a large breathing resistance, which makes it difficult for the user to breathe, and the product defects are obvious. One is th...
