Description
Technical Field
The utility model belongs to the technical field of the medical treatment, especially, relate to a cup type cavity protective facial mask.
Background
Conventionally, masks have been widely used for preventing colds, preventing dust from being adsorbed, and the like. In addition, the mask is also used to alleviate pollinosis in spring when pollen is scattered. As is well known, the mask is an indispensable protective product for workers in infection sources and dust environments, and if the mask is not designed well, the resistance is too large, so that the breathing difficulty is caused, the health of the workers is injured, and the healthy development of the industry is not facilitated. As for the existing cup-shaped mask, the one-step forming design is adopted, the one-step formed product has large breathing resistance, the breathing of a user is difficult, and the product defects are obvious. Firstly, the current cup type gauze mask that adopts one shot forming causes the resistance of breathing in too big when satisfying filtering efficiency, often causes the person of wearing, breathes unsmoothly after wearing, causes the work efficiency to reduce. Secondly, because the mask mainly has the purpose of shielding the mouth and the nose to prevent the mask from being infected by the outside and harmful substances from being inhaled, and the mask is basically in a working state when being worn generally, the breathing resistance problem and the visual field shielding problem of a wearer need to be fully considered when the mask is designed, so that the whole inhalation permeation resistance of the cup-shaped mask is too large, the breathing is difficult when the mask is worn, the smoothness of inhalation is seriously influenced, the working efficiency is finally low, and the mask becomes a physical burden for the wearer. How to adopt a new cup type cavity protective facial mask production method, reduce the smooth and easy nature of breathing of the person of wearing, improve the comfort that the gauze mask was worn, improve original one shot forming's cup type gauze mask production technology, under the prerequisite that does not reduce protective capacities, increase the resistance buffering of breathing in, reduce the respiratory resistance, improve and use the comfort and be the problem that must solve.
A general mask includes a mask body covering nostrils and a mouth of a cheek, and a rubber band for holding a hanging lug of the mask body. Conventionally, masks using nonwoven fabrics, masks having a three-dimensional shape for the purpose of improving adhesion, masks using special filters such as electrostatic filters, and the like have been used in common applications, in addition to conventional masks using gauze in a planar shape. The existing cup-shaped protective mask is produced by adopting a one-time forming technology, the breathing resistance is large under the condition of meeting the filtering effect, the comfort is very poor when the mask is worn, the oppression phenomenon during breathing can be caused, and the air resistance of the mask is large.
