Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

Referring to fig. 1 to 5, the cup-shaped mask includes a mask body and a strap 1, and is characterized in that the mask body includes:

a mask 2 for fixing the strap 1, having a raised part 2a raised to the outside, the inner side of the raised part 2a forming a breathing cavity a completely covering the nose and mouth of the wearer, the mask 2 being press-molded from a skin-friendly and highly breathable fabric;

and a filter assembly 3 fixedly installed outside the mask 2, completely covering the raised part 2a of the mask 2 and forming a filter chamber B with the mask 2 for filtering air entering the mask body from the outside.

The wearer breathes and produces that the air current drives the empty filter chamber B that gets into of external world, realizes the filter effect to the air in the in-process that gets into filter chamber B, and the air that gets into in filter chamber B passes face guard 2 along with the breathing process and gets into wearer's oral cavity and nasal cavity.

Face guard 2 in this application is for being close to skin and the cloth of high gas permeability supports, and main look is guaranteed to wear the comfort level and with the facial degree of laminating of wearer, and high gas permeability is favorable to guaranteeing respiratory patency, and the filter effect can be not considered completely in the material selection of face guard 2, and the filter effect of whole gauze mask is realized by filter component 3.

The filter assembly 3 includes:

the front side closing part 3a is of a flat plate type structure made of low-permeability cloth and is vertically arranged on the front side of the mask body, and a ventilation window 3a1 communicated with the filter cavity B is arranged on the front side closing part 3 a;

a front filter member 3b which is a rectangular plate-shaped filter member made of a material having an air filtering effect, is fixedly attached to the back side of the front closure member 3a and completely covers the louver 3a 1;

the peripheral side filtering support part 3c is a closed ring formed by surrounding a flexible rectangular strip made of a material with an air filtering effect around the edge of the raised part 2a of the face mask 2, one end of the closed ring is fixedly connected with the outer side of the face mask 2, the other end of the closed ring is fixedly connected with the back side of the front side closing part 3a, and the region surrounded by the closed ring forms the filtering cavity B.

The front side filter component 3b is a rectangular wave plate made by folding the long strip rectangular composite filter cloth from the short side repeatedly at equal intervals.

The peripheral filtering support part 3c is formed by the enclosure of rectangular wave plates formed by folding the strip-shaped composite filtering cloth repeatedly at equal intervals from the short sides.

The composite filter cloth for preparing the front side filter element 3b and the peripheral side support filter element at least comprises a first outer cloth layer, a second outer cloth layer and a middle cloth layer positioned between the first outer cloth layer and the second outer cloth layer, wherein the first outer cloth layer and the second outer cloth layer are high-permeability foldable and shaped cloth layers.

The middle cloth layer can be melt-blown cloth, nano cloth or other fabrics with filtering capability.

The front closing member 3a is made of a low air permeability fabric to ensure that air introduced into the filter chamber B must be filtered by the front filter member 3B and the peripheral side filter support member 3 c. In an extreme case, the front-side closing member 3a may not consider the air permeability at all.

The front filter element 3b is in the main force direction of the breathing gas flow and acts as a main filter for the gas in the whole filter element, so that a very strong filtering capacity is required. Since the front filter element 3b is mounted on the louver 3a1, the louver 3a1 cannot be very large due to the size of the human face, and therefore the area of the front filter element 3b covered on the louver 3a1 is limited, and it is necessary to increase the filter area as much as possible in the case of a fixed area, and this scheme is adopted in which the filter material is folded to enlarge the contact area between the airflow and the front filter element 3 b. Namely, the paper or cloth with high air permeability and filtering capacity is folded and shaped, and is fixed at the position of the louver 3a1 by glue, because of the folding treatment, the area of the filtering material contacted by the air passing through the louver 3a1 with a fixed size is far larger than the area of the louver 3a1, and when the air passes through the filtering material, part of the air may pass through the filtering material for many times due to the folding effect, thereby improving the filtering capacity.

In terms of filtering capacity, the peripheral side filtering support component 3c is the same as the front side filtering component 3b, namely, a piece of paper or cloth with high air permeability and filtering capacity is folded and shaped, and finally, the peripheral side filtering support component is fixedly connected with the front side seam closing component and the face mask 2 through glue. In contrast, the peripheral side filter support member 3c has a certain support strength.

Activated carbon particles are attached to gaps of the rectangular wave plate formed by folding, and wrapping layers are bonded to the front surface, the back surface and the two long side edges of the rectangular wave plate at least and are high-air-permeability cloth layers.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the principles of the present invention may be applied to any other embodiment without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
