Description

Technical Field

[0001] The invention relates to a foldable nose mask, in particular to a foldable nose mask which completely covers the front end of a user's nose and covers the sides of two nostrils of the user. Background Art

[0002] In order to block the inhalation of pollutants, allergens, and even pathogens in the air, people generally use masks to filter these harmful substances in the air; however, since the mask has a large area and needs to be fixed with additional straps, the cost of materials and manufacturing is increased. In addition, the mask will cover the user's mouth and nose and easily touch the eyes when used. In addition to affecting the appearance and social perception, it is not convenient for normal life activities such as talking, exercising, sleeping, seeing a dentist, or eating, and it is easy to cause discomfort such as humidity and stuffiness. In particular, the use of N95 masks will leave indentations on the face. Moreover, the mask is easily affected by the contour of the face, making it difficult to achieve good airtightness when worn.

[0003] In order to improve the above-mentioned problems, many nasal plugs containing filter materials have been developed to improve portability and aesthetics. However, although such products can significantly reduce the size, they are not easy to wear for a long time due to their high invasiveness, and are easy to wear incorrectly due to their complex structure and composition. In addition, they are fixed at the user's nasal entrance, especially the front part of the nose, which not only easily affects the smoothness of breathing, but are also more likely to fall off, and cannot completely prevent the nasal cavity from contacting harmful substances in the air.
