Description
Technical Field
The invention relates to the technical field of masks, in particular to a mask filtering structure.
Background
The filter capacity through the melt-blown cloth of valveless gauze mask most realizes the filter effect of gauze mask, and the inhaled air will be filtered through one deck melt-blown cloth, and the filter capacity of melt-blown cloth has decided the filter capacity of gauze mask promptly, and the thickness of melt-blown cloth is thicker, and the filter capacity is stronger, but can reduce the gas permeability of gauze mask when improving melt-blown cloth thickness.
The cup-shaped transmission mask is designed by three layers of non-woven fabrics, the outermost layer is a PP non-woven fabric, the middle filter layer is high-efficiency melt-blown fabric, and the inner layer is high-quality acupuncture cotton. The three layers of cloth are formed by performing ultrasonic welding on the edges after the three layers of cloth are subjected to hot-press forming and stacking layer by layer. The melt-blown fabric in the middle layer covers the whole mask area, and a relatively small breathing space is formed between the nose and the inner side of the mask due to the fact that the mask is relatively close to the nose and the mouth of a wearer, so that the mask bears air filtering work just at the position of the mouth in the wearing process, namely the middle layer flannelette in the area is used for filtering air, and the middle layer melt-blown fabric in other areas is not used for filtering air.
In addition, above-mentioned traditional gauze mask is because breathing cavity is narrow, and the gauze mask can't be passed to the steam that produces among the person's the breathing process, stops and can greatly influence the comfort level of wearing at the inboard steam of gauze mask.

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 3, a mask filter structure installed at an outer side of a mask body 1 includes:
the front side closing part 3a is a flat plate structure made of low-permeability cloth and is vertically arranged at the front side of the mask body 1, and a ventilation window 3a1 communicated with the filter cavity 2 is arranged on the front side closing part 3 a;
a front filter member 3ab 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 3ac 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 of the face mask, one end of the closed ring is fixedly connected with the outer side of the face mask, 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 2.
The front side filter component 3ab 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 side filtering and supporting component 3ac is formed by the enclosure of rectangular wave plates made by folding the strip-shaped composite filtering cloth repeatedly at equal intervals from the short side.
The composite filter cloth for preparing the front side filter component 3ab and the peripheral side support filter component 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 middle cloth layer is melt-blown cloth, and the first outer cloth layer and the second outer cloth layer are high-permeability foldable and shaped cloth layers.
The front closure member 3a is a low air permeability fabric to ensure that air entering the filter chamber 2 must be filtered by the front filter member 3ab and the peripheral side filter support member 3 ac. In an extreme case, the front-side closing member 3a may not consider the air permeability at all.
The front filter element 3ab is in the main force direction of the breathing gas flow and functions 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 member 3ab 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 member 3ab covering 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 member 3 ab. 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 capability, the peripheral side filtering support component 3ac is the same as the front side filtering component 3ab, namely, a piece of paper or cloth with high air permeability and filtering capability 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 through glue. In contrast, the peripheral side filter support member 3ac has a certain support strength.
The first outer cloth layer and the second outer cloth layer are both low-melting-point and high-melting-point mixed polyester staple fiber blended cloth, wherein the weight ratio of the low-melting-point polyester staple fibers is 40-60%, and the weight ratio of the high-melting-point polyester staple fibers is 40-60%.
Since the meltblown fabric has a poor foldable type, it is required that the first and second outer fabric layers have a good foldable type. The mixed polyester staple fiber blended fabric with low melting point and high melting point has good foldable shape and good shaping effect after being folded. In particular, the supporting requirements of the peripheral side filter support member 3ac can be satisfied.
The first outer fabric layer and the second outer fabric layer have an average grammage of 60 to 120g per square meter.
The first outer cloth layer and the second outer cloth layer are formed by hot pressing and have a thickness of 0.3 mm-0.6 mm.
It should be noted that, after the first outer cloth layer and the second outer cloth layer are hot-pressed and formed to be only 0.3 mm-0.6 mm, the folding effect is better, the folding is convenient, and the hot-pressing setting temperature range is 150 degrees-180 degrees.
The mask body 1 is formed by pressing skin-friendly and highly breathable cloth.
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 embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
