Technical Field

The utility model relates to a health supplies and labor protection field, concretely relates to self-adaptation type nose gauze mask.

Background

Because of the environmental pollution problem and the global outbreak and spread of novel coronavirus, people pay more and more attention to the protection against bacteria, viruses, pollutants and the like, and the mask plays a vital role in daily protection. In order to provide effective protection, it is necessary to prevent leakage of exhaled air and intrusion of external air during use of the mask. And in fact, wear ordinary gauze mask, because the bridge of the nose of wearer is higher, can be with gauze mask center department jack-up to make gauze mask and the relative part in bridge of the nose both sides not laminate, produce huge gap, influence the sealed effect and the filter effect of gauze mask. When the mask is worn, particularly when the mouth or the jaw of a wearer moves up and down in a conversation, the wearing position is easy to be misplaced, so that the purposes of preventing exhalation leakage and external air invasion are achieved, an effective protection effect cannot be achieved, meanwhile, the misplacement during wearing also brings uncomfortable experience to the wearer, and the user protects the wearing mask to generate the emotion resistance.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the defects of the prior art and providing a nasal mask with high comfort level and good airtight effect.

The technical scheme of the utility model is that: the self-adaptive nose mask comprises a framework system, a filtering system and a wearing and fixing system, wherein the framework system is used for manufacturing a framework outline according to the basic shape of a nose of a human face, and the filtering system is positioned at the inner side of the framework system and covers the mouth and nose of a wearer; a laminating system made of flexible materials is arranged on the outer side of the framework system; the wearing and fixing system is arranged on the left side and the right side of the skeleton system and is formed by a belt-shaped telescopic material.

The fit system forms a U-shaped structure in its extension. The U-shaped structure is an outer U-shaped structure or an inner U-shaped structure.

The wearing fixing system is fixed with the framework system through the linking part.

Wear fixed system and laminating system integrated into one piece.

The surfaces of the inner sides of the skeletal system and the filtration system are not in contact with the skin of the wearer.

The fit system forms wings on the nose and on both sides of the nose.

The utility model has the advantages that the framework system is formed by making the framework outline according to the basic shape of the nose of the human face, the covering area of the mask surface of the nose is small, and the comfort level of the mask is improved; meanwhile, the fitting system on the periphery of the framework system is tightly fitted with the face of a wearer, the adopted material has elastic deformation, and the opening and closing mouth or jaw of the wearer cannot be dislocated during up-and-down movement during conversation, so that a good and comfortable closed system can be formed even if the wearing position is dislocated, and the safety and the comfort of mask protection are improved.

Detailed Description

The utility model discloses self-adaptation type nose and mouth mask mainly includes laminating system 1, skeleton system 2, filtration system 3 and wears fixed system 4, and skeleton system 2 manufactures the skeleton profile according to the basic shape of human facial nostril department, and the material of material for relative stereoplasm that adopts, like metal, composite fiber, plastics etc. all can regard as skeleton system 2's material, skeleton system 2 plays the supporting role. The filtering system 3 is a nose and mouth shield protection core, is positioned on the inner side of the framework system 2, is supported by the framework system 2, covers the mouth and nose parts of a wearer after being worn, and plays a role in filtering the gas exhaled by the user to block the spray. The surface of the inner side of the framework system 2 and the filtering system 3 is not contacted with the skin of a wearer, the problems of discomfort caused by the fact that the mask is contacted with the mouth and the nose and the filtering effect is reduced are avoided, and the comfort and the protection effect of the nose mask are improved. Laminating system 1 sets up in skeleton system 2 outside, is made by flexible material, and elastic material such as silica gel, rubber, latex, elastic foaming, TPU, elastic engineering plastics, leather, synthetic leather (PU) can be chooseed for use to flexible material, utilizes laminating system 1 flexible material's deformation, makes nose mask and nose mouth department facial laminating reach comfortable perfect laminating. After wearing the nose mask, the attaching system 1 can be closely attached to the nose and the face, so that the sealing effect is achieved, and the breathing leakage and the external gas invasion are prevented. In order to further enhance the fit of fit system 1, in addition to selecting a suitable flexible material, this may be accomplished by designing the structure of fit system 1 itself. In the first structure, as shown in fig. 5, the attachment system 1 extends to form an outer U-shaped 6 structure, the U-shaped structure is located outside the face contact surface, the U-shaped design makes the elastic deformation space range of the attachment system 1 larger, and the attachment effect is better. In the second structure, as shown in fig. 6, the fitting system 1 is extended to form an inner U-shaped 7 structure, i.e. the U-shaped structure is located at the inner side of the face contact surface, the inner U-shaped 7 structure can increase the deformability of the fitting system 1, and the inward-folded structure makes the mask smaller and more beautiful.

The mask is most prone to air leakage at the nose bridge and two sides, and the nose bridge is not safe in protection due to exhalation leakage, glasses of a user wearing the glasses are fogged, sight is affected, and safety and comfort of the mask are reduced. In this embodiment, the attaching system 1 forms the blocking wings 9 on both sides of the nose, as shown in fig. 7, the blocking wings 9 conform to the skeleton system 2 and the attaching system 1, the concave part 8 of the nose of the mask is correspondingly concave, the blocking wings 9 have elastic deformability, the nose of a user has height difference, the skeleton system 2 designed by using the 3D printing technology can adapt to most people, but when the basic shape with too large difference cannot be perfectly adapted, the blocking wings 9 have malleability in the vertical direction to the face and in the direction to the bridge of the nose, when the nose is high, the blocking wings 9 are completely unfolded and sealed, when the nose is short, the blocking wings 9 are slightly unfolded or even compressed, the sealing attachment is maintained, and the sealing effect and reliability at the bridge of the nose can be improved.

The utility model discloses wear fixing system 4 and set up in the left and right sides of skeleton system 2, form by banded elasticity material, fix nose mask at ear or head. In the embodiment, two connection and fixing modes between the wearing and fixing system 4 and the mask main body are provided, the first mode is that the wearing and fixing system 4 is connected with the mask main body in a split mode, as shown in fig. 1, the wearing and fixing system 4 is fixed with the framework system 2 through a link part 5; secondly, the wearing fixing system 4 is connected with the mask body as a whole, and as shown in fig. 3, the wearing fixing system 4 and the fitting system 1 are integrally formed.

The utility model discloses a nose gauze mask structural design is reasonable, and laminating system 1, skeleton system 2 and filtration system 3 combine together, keep closely laminating with facial when making gauze mask coverage area reduce, and the travelling comfort is good, and the protection safety degree is high.
