The paster and the portion of subsides of bandeau 6 cooperate, are convenient for improve bandeau 6's installation effectiveness, and simultaneously, be convenient for realize automatic installation bandeau 6, help improving protective facial mask's production efficiency.

The utility model discloses a theory of operation is:

because the existing mask is mostly a plane mask, a lot of inconveniences still exist when the mask is used, the space formed between the mask and the face is small, so that a user feels uncomfortable, and under the action of internal pressure or external force, the mask is easy to shake, and the protection effect of the mask is influenced, therefore, a reinforcing part 3 with parallel folding lines 2 is arranged on the inner side of the mask body 1, the area above the folding lines 2 and the area below the folding lines 2 are ensured, a three-dimensional structure is kept when the mask is used, a large space can be formed between the mask and the face, a nose bridge and a mouth are just covered by a protruding part at the front end of the mask body 1, a certain space is reserved between the nose bridge and the mouth, the mask is more favorable for breathing and communication, the contact area between the gas exhaled by a human body and a filter layer on the inner side of the mask body 1 is, the breathing airflow is smoother, and the comfort of wearing the mask is improved; the plurality of reinforcing parts 3 are adopted, so that the overall strength of the mask can be improved, the mask body 1 can bear internal pressure or external force within a preset range, a complete three-dimensional structure is always kept, and the probability of shaking or deformation of the mask in use is reduced; in addition, when the cover body 1 is used, the cover body 1 is a semi-elliptical ball, the perimeter of the cover body 1 is gradually reduced along the direction from the top of the cover body 1 and also gradually reduced along the direction from the folding line 2 to the bottom of the cover body 1, in order to match the structure of the cover body 1, the length of one part of the reinforcing part 3 is also gradually reduced along the direction from the folding line 2 to the top of the cover body 1, and the length of the other part of the reinforcing part 3 is also gradually reduced along the direction from the folding line 2 to the bottom of the cover.

Example 2

The difference from example 1 is: the broken line 2 of this embodiment sets up in the middle part of the cover body 1, and a plurality of reinforcement 3 uses broken line 2 to set up as symmetry axis symmetry, and buffer 5 is the silica gel piece, and the filter layer is for melting the non-woven fabrics. The folding line 2 is transversely arranged in the middle of the mask body 1, the mask body 1 adopts a design taking the folding line 2 as a symmetry axis, and in order to adapt to the symmetrical design, the plurality of reinforcing parts 3 are symmetrically arranged by taking the folding line 2 as the symmetry axis, so that the mechanical strength of the upper area and the lower area of the folding line 2 is equally increased, and the mask is made into a vertically symmetrical three-dimensional structure; the two polypropylene non-woven fabrics are respectively positioned at the outermost layer and the innermost layer of the mask body, the melt-blown non-woven fabric and the common non-woven fabric are respectively positioned between the two polypropylene non-woven fabrics, and the common non-woven fabric is in contact with the polypropylene non-woven fabric at the inner layer, so that the number of filter layers between the adjacent non-woven fabrics can be increased according to the actual product requirements; the silica gel piece has better cushioning effect, helps improving the comfort level of contacting with the nose to improve the travelling comfort of wearing the gauze mask.

The other structures are the same as those of embodiment 1, and are not described again here.

Example 3

The difference from example 1 is: the folding line 2 of the embodiment is transversely arranged in the middle of the cover body 1, and the number of the reinforcing parts 3 on the upper side of the folding line 2 is less than or equal to that of the reinforcing parts 3 on the lower side of the folding line 2. In order to adapt to the vertically asymmetric design, the number of the reinforcing parts 3 on the upper side of the folding line 2 is less than or equal to that of the reinforcing parts 3 on the lower side of the folding line 2, so that the requirements of different reinforcing areas are met, and the mask is more diversified.

Variations and modifications to the above-described embodiments may become apparent to those skilled in the art from the disclosure and teachings of the above description. Therefore, the present invention is not limited to the above-mentioned embodiments, and any obvious modifications, replacements or variations made by those skilled in the art on the basis of the present invention belong to the protection scope of the present invention.
