[0021] Referring to Figs. 1-3As shown, an improved N95 mask includes an N95 mask body 1, and ear hanging ropes 2 connected on both sides of the N95 mask body 1. Each of the two ear hanging ropes 2 is connected with a tightness adjusting assembly 3; the tightness adjusting assembly 3 includes a spring buckle 31 and a rope anti-pulling sleeve 32 abutting one end of the spring buckle 31, and the outer periphery of the rope anti-pulling sleeve 31 is further wrapped with a skin-friendly protective sleeve 33. The ear hanging ropes 2 on the same side are disconnected from the middle part and divided into two, and the ends of the two ear hanging ropes 2 are respectively correspondingly inserted from both ends of the rope anti-pulling sleeve 32, and are drawn out from the middle part of the rope anti-pulling sleeve 32, and are gathered and connected on the spring buckle 31, and the tightness of the ear hanging ropes 2 is adjusted through the spring buckle 31; in order to make the rope anti-pulling sleeve 32 more fit the contour of the human ear, the rope anti-pulling sleeve 32 is designed as a pipe with a C-shaped structure, and the two ends of the C-shaped rope anti-pulling sleeve 32 are provided with rope inlet ports 321, and the outer side of the middle part of the C-shaped rope anti-pulling sleeve 32 is provided with a rope outlet port 322; since the skin-friendly protective sleeve needs to be wrapped outside the rope anti-pulling sleeve, the skin-friendly protective sleeve 33 is matched with the shape of the rope anti-pulling sleeve 32, and is also a tubular structure with a C-shaped structure, the skin-friendly protective sleeve 33 is made of cotton or silica gel material, and the rope anti-pulling sleeve 32 can be made of rubber material, and has moderate hardness, and can be easily inserted into the skin-friendly protective sleeve 33 during installation, and then the ends of the two ear hanging ropes 2 are respectively inserted from the two rope inlet ports 321 and drawn out from the rope outlet port 322; when worn, the rope anti-pulling sleeve is located behind the ear and above and below the ear, and the C-shaped structure can form good wrapping protection, reduce the compression force of the ear hanging ropes 2 on the auricle in the pulling state, and prevent the ear from being pulled. The N95 mask body 1 is provided with a plastic strip 11 corresponding to the position of the human nose bridge inside, and the inner side surface of the N95 mask body is fixedly connected with a water-absorbing cotton strip 12 corresponding to the position of the plastic strip 11, and the two ends of the water-absorbing cotton strip 12 extend to the two side edges of the N95 mask body 1, and the position of the water-absorbing cotton strip 12 corresponds to the nose bridge to the zygomatic bone on both sides of the cheek, and the water-absorbing cotton strip 12 can improve the fit and comfort of the mask on the nose bridge, and at the same time can form a sealed band that blocks exhaled air, so that even if the exhaled gas passes through, most of the water vapor can be isolated, preventing the phenomenon of fogging of glasses. The inner side of the N95 mask body 1 is fixedly connected with a skin-friendly protective film 13 matching in shape along the edge; the skin-friendly protective film 13 is made of silica gel material, and the skin-friendly protective film 13 and the N95 mask body 1 can be fixedly connected by adhesion or heat fusion, and the edge contour of the N95 mask body 1 is located inside the skin-friendly protective film 13, such as Fig. 2As shown, the dotted line represents the edge outline of the N95 mask body 1. When the edge of the N95 mask body 1 is in contact with the human face, due to prolonged wear, the edge will be pressed into the human cheek. The edges of existing N95 masks are relatively hard, which can easily leave indentations or even cause peeling. However, the skin-friendly protective soft sheet 13 can provide good protection when the edge is in contact with the face, reducing local pressure and preventing indentations, peeling, or even pressure sores.
[0022] This invention uses a spring buckle 31 to adjust the tightness of the ear loops 2, which can be adjusted according to different head sizes to ensure a close fit between the mask and the face. Furthermore, the ear loops 2 are fitted with anti-stretching loop sleeves 32, and these sleeves are covered with a skin-friendly protective cover 33. When worn, the anti-stretching loop sleeves 32 are positioned behind and above the ears, reducing the pressure on the earlobes when the ear loops 2 are pulled, thus preventing ear chafing. A skin-friendly protective soft sheet 13 is also provided where it contacts the face to prevent pressure sores caused by the hard material at the edges of the N95 mask body 1. An absorbent cotton strip 12 is designed in the nose bridge area, which, with the help of the shaping strip 11, fits the nose bridge better, improving comfort and sealing, and preventing exhaled air from spraying upwards and causing fogging in the eyes.
[0023] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of the technical solution of this utility model.
