Description

Gauze mask

Technical Field

The utility model relates to a health protection articles for use technical field especially relates to a gauze mask.

Background

Because large-scale urban construction, industrial production and motor vehicles are greatly increased in recent years, serious physical pollution and chemical pollution are brought. In recent years, haze pollution continuously occurs in most areas of China. The particles with the aerodynamic equivalent diameter less than or equal to 2.5 mu m, also called fine particles (PM 2.5), are easy to enrich harmful substances in the air due to small particles and large specific surface area, can enter the human body along with respiration, even enter pulmonary alveoli or blood circulation systems of the human body, directly cause diseases of cardiovascular and respiratory systems and the like, and are the basic cause of damaging the human health in urban atmospheric pollutants. In addition to reducing the source of PM2.5, protection against PM2.5 is also an important aspect, and for daily life, the most widespread means of protection is by the choice of wearing a mask.

Two types of masks are commonly used in the market at present, one type of mask is provided with a plastic framework, the mask utilizes the framework to separate a certain space from a human face, and a user can breathe relatively more smoothly, but the mask is inconvenient to store and is complex in production operation due to the plastic framework; the other type is a mask without a framework, the mask is convenient to store, but the breathing resistance is relatively high due to the fact that no framework supports the mask, the mask is easy to fit with a human face, and inconvenience in use is caused.

Optionally, the mask further comprises ear lines at two ends of the main body of the mask, in addition to the main body.

The utility model provides a five layers of stack designs of gauze mask main part can stable support certain space before inlayer and face nasal part, guarantees getting rid of that the waste gas of exhalation can be smooth and easy, avoids glasses fog etc. in winter. Set up two-layer filter layer from top to bottom at flexible skeleton, guarantee that inspiratory gas obtains abundant filtration, avoid the side leakage, and convenient storage, the machining of being convenient for saves the cost.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without inventive exercise.

Fig. 1 is a schematic structural view of a mask body material provided in an embodiment of the present invention.

Fig. 2 is a schematic structural view of a mask provided by an embodiment of the present invention.

Illustration of the drawings: the filter comprises a main body 1, an ear line 2, an aluminum strip 11, a first filter layer 12, a second filter layer 13, a flexible framework 14, a third filter layer 15 and an inner support layer 16.

Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and obviously, the embodiments described below are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1 and 2, in this embodiment, the main body 1 of the mask has a five-layer structure, and includes a first filter layer 12, a second filter layer 13, a flexible skeleton layer 14, a second filter layer 15, and an inner support layer 16, which are sequentially disposed; namely, the second filter layer 13 is arranged below the first filter layer 12, and a flexible skeleton layer 14, a third filter layer 15 and an inner support layer 16 are arranged below the first filter layer 12 in sequence.

Further, all layers of the main body 1 of the mask are mutually independent and are sequentially laminated and compounded, and the laminating and compounding mode can be one or more of ultrasonic bonding, high-temperature hot-pressing sewing and adhesive compounding modes.

Furthermore, the first filter layer 12 is a PP nonwoven fabric layer, which not only can play a role of primary filtration, but also can effectively filter particles with a particle size of less than 3 microns; can also be used as an external decorative layer, can be printed with trademarks, patterns and the like, and achieves the effect of propaganda and beauty. The second filter layer 13 is a first melt-blown cotton layer and is used for filtering PM2.5 (particulate matters with the particle size of less than 2.5 microns).

Furthermore, the third filter layer 15 is a second melt-blown cotton layer, which not only can filter the air filtered twice again, but also can filter the air entering from the side face, so as to prevent side leakage. The inner supporting layer 16 is a non-woven fabric layer, the non-woven fabric layer is used as a new generation of environment-friendly material, and the mask has the advantages of moisture resistance, air permeability, flexibility, no toxicity, no irritation and the like, is very suitable for being used as a mask manufacturing material, and can play a role in further filtering.

Further, the flexible skeleton layer 14 is a warp-knitted spacer fabric structure, so that a certain space is formed between the first filter layer 12 and the second filter layer 13 and between the third filter layer 15 and the inner support layer 16, and a sufficient flowing space is reserved for air between the second filter layer 13 and the third filter layer 15, so that when the main body 1 of the mask sucks external air, the external air is firstly filtered by the first filter layer 12, and then is filtered again by the second filter layer 13, and smoothly circulates in the three-dimensional space of the flexible skeleton 14 and is sucked after being filtered by the third filter layer 15 and the inner support layer 16, so that the air suction of a user is smoother, the condition that the mask main body is attached to a surface is avoided, and the mask is convenient for mechanical production and convenient for storage.

Further, an aluminum strip 11 is transversely arranged in the main body 1 at the position where the main body 1 contacts the bridge of the nose.

The mask further comprises ear lines 2 at two ends of the main body of the mask, in addition to the main body 1.

The gauze mask of this embodiment not only can guarantee getting rid of that the waste gas of exhalation can be smooth and easy, avoids glasses fogging etc. in winter. Can also guarantee that inspiratory gas obtains abundant filtration, avoid the edge leakage, and convenient storage, the machining of being convenient for saves the cost. Not only can reach efficient barrier propterty, but also has higher wearing comfort level and wide market space.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the embodiments of the present invention.
