Description

Facial mask

This creation is related to masks.

Masks can effectively filter the air to isolate harmful substances such as bacteria, viruses, particles, droplets, etc., to ensure that the air inhaled by the wearer is clean. Depending on the timing and purpose of use, masks can be divided into: general masks for cleaning, surgical masks that can block more than 90% of 5 micron particles, activated carbon masks that remove odor and toxic dust, and more than 95% of sub-micron particles. N95 masks.

Traditionally common masks are mainly flat in order to facilitate stacking, storage and transportation. However, such flat masks have poor fit when used, and can easily cause gaps when they cannot match face changes, and they put great pressure on the face. , The strong airflow resistance leads to undesirable conditions such as difficulty breathing and heat accumulation.

Therefore, it is necessary to provide a novel and progressive mask to solve the above-mentioned problems.

The main purpose of this creation is to provide a mask that can effectively provide a three-dimensional space for the wearer and give the wearer a sense of comfort.

In order to achieve the above-mentioned purpose, this creation provides a mask, including: a mask body, a nose bridge, and a molding part. The mask body includes at least two crimping areas; the nose bridge strip is arranged on the mask body, the nose bridge strip is used for pressing on the nose; the molding part is arbitrarily bent and shaped by the outside, and the molding part is spaced from the nose bridge. Located on the mask body, the plastic part includes two ends and a middle section. The two ends are respectively positioned in the at least two crimping areas. The middle section is connected between the two ends and can be used for the two ends. The part is a fulcrum that swings freely relative to the mask body.

The following examples are only used to illustrate the possible implementation of this creation, but it is not intended to limit the scope of protection of this creation, and it is first described.

Please refer to FIGS. 1 to 4, which show an embodiment of this creation. The mask of this creation includes: a mask body 1, a nose bridge 2 and a molding part 3.

The mask body 1 includes at least two crimping areas 11. The nose bridge strip 2 is arranged on the mask body 1, and the nose bridge strip 2 is pressed on the nose, so that the upper periphery of the mask body 1 can stably fit the nose bridge and face of the wearer. The plastic part 3 can be bent and shaped arbitrarily by the outside world. The plastic part 3 is arranged on the mask body 1 with the nose bridge 2 separated. The plastic part 3 includes two ends 31 and a middle section 32. The two ends The portions 31 are respectively positioned in the at least two crimping regions 11, the middle section 32 is connected between the two end portions 31 and can swing freely relative to the mask body 1 with the two end portions 31 as fulcrums.

By bending the molding part 3, the mask body 1 can be supported and arched, so that the mask body 1 can be kept spaced from the nostrils and mouth of the wearer. In other words, the mask body 1 in a planar shape passes through the molding part 3 The plastic type maintains a three-dimensional shape, providing more three-dimensional space margin, ensuring that the wearer will not feel no pressure, smooth breathing, and no heat accumulation. More importantly, the middle section 32 can swing correspondingly with the face of the wearer, so that the mask body 1 can fit the face more closely, improve the fit and reduce the gap, and can better adapt to different wearers. Establish a three-dimensional space model that meets the needs.

For example, but not limited to, swinging the middle section 32 to the tip of the nose can increase the contact area with the nose and have better stable support. Or, swinging the middle section 32 to the chin to tighten the mask body 1 can effectively prevent the mask body 1 from expanding or contracting with the airflow, ensuring the maintenance of the three-dimensional space.

The mask body 1 defines a length direction 41 and a width direction 42. In detail, the mask body 1 includes two opposite first sides 16 in the length direction 41, and the mask body 1 includes in the width direction 42 There are two opposite second sides 17, the two first sides 16 are transversely connected to the two second sides 17, the number of the at least two crimping areas 11 is four, and the two crimping areas 11 are along the width direction 42 Extending on the two first side edges 16, the other two crimping regions 11 extend on the two second side edges 17 along the length direction 41.

In more detail, the nose bridge 2 is confined to the crimping area 11 of a second side edge 17, and the molded part 3 extends from a first side edge 16 to another along the length direction 41. In the length direction 41 of the first side edge 16, the length of the molded part 3 is greater than the length of the nose bridge 2.

In the first embodiment, the molded part 3 is in a straight strip shape, and the ratio of the length of the molded part 3 to the length of the nose bridge 2 is between 1.2 and 1.7, which can have better shaping ability ; Among them, the width of the plastic part 3 is equal to the width of the nose bridge 2 to facilitate overall planning and manufacturing.

It is understandable that the at least two crimping regions 11 are formed by welding and pressing. Preferably, the two ends 31 of the plastic part 3 are simultaneously pressed and positioned on the mask body 1 during the welding and pressing process. At the same time, the two ends of the two ear straps 18 are respectively positioned on the two crimping areas 11 of the two first side edges 16, so the two ear straps 18 and the plastic part 3 can be fixed at the same time during the welding and crimping process. Effectively simplify processing steps and improve production efficiency.

Please further refer to the second embodiment shown in FIGS. 5-6. The difference from the first embodiment is that the shape of the plastic part 3A is different. Specifically, the two end portions 31A are strip-shaped, and the middle portion 32A is The plate-shaped middle section 32A can provide more area for the wearer to decide whether to increase the mutual contact area, and the plate-shaped middle section 32A can provide more support for the mask body 1, and Can have better shaping ability.

Preferably, the middle section 32A includes a plurality of vents 33, the opening direction of each vent 33 is equivalent to a filtering direction 43, the filtering direction 43 is perpendicular to the length direction 41 and the width direction 42, each of the vents 33 in order to ensure the smoothness of air flow during breathing.

Please further refer to the first embodiment shown in FIGS. 1 to 4. The mask body 1 includes two surface layers 12 and at least one inner layer 13. The at least one inner layer 13 is sandwiched between the two surface layers 12, and the two surface layers The at least one inner layer 12 and the at least one inner layer 13 are welded and connected into a whole through the at least two crimping regions 11; wherein, the molded part 3 is located between the at least one inner layer 13 and the surface layer 12.

More specifically, the mask body 1 has a plurality of pleats 14 recessed along the width direction 42. The pleats 14 of the surface layer 12 are not sinked into the pleats 14 of the at least one inner layer 13, and then the pleats 14 are in the plural pleats. 14 Before being stretched, the surface layer 12 and the at least one inner layer 13 define a movable space 15 in the filtering direction 43. Therefore, when the mask body 1 is not stretched and worn, the middle section 32 of the plastic part 3 It is already possible to move freely in the activity space 15. The above-mentioned structural configuration allows the plastic part 3 to have a better degree of freedom of movement at each stage of use, and can ensure that the plastic part 3 will not be back-folded by the machine during the process of manufacturing the plurality of folds 14 The structure of the plastic part 3 can be kept intact.

More specifically, before the mask body 1 is stretched, the molded part 3 is located within a range of the pleat 14 in the width direction 42 without protruding, so as to maintain the structure of the pleat 14. Moreover, in the width direction 42, the two end portions 31 are respectively positioned at the center of the two first side edges 16 before being stretched, so that the vertical swing range can be taken into consideration.

It is worth mentioning that, please refer to the third embodiment of FIG. 7 and the fourth embodiment of FIG. 8, the molding parts 3B, 3C can also be used outside the mask body 1B, 1C, which allows the wearer to change Directly control the adjustment position.
