Description

Technical Field

[0001] This utility model belongs to the field of aviation oxygen supply masks, specifically relating to a low-profile aviation oxygen supply mask body that improves physiological state at high altitudes. Background Technology

[0002] Existing aviation oxygen supply masks are connected to the oxygen supply system via oxygen supply pipes. At high altitudes, due to the influence of external environmental pressure, the cabin air pressure is no longer sufficient to provide oxygen. The oxygen supply system must then provide the required oxygen to the personnel through the aviation oxygen supply mask. The mask is worn on the pilot's face, covering the mouth and nose, to provide oxygen for breathing. As the aviation oxygen supply mask is closest to the human body, it is a critical point of human-machine interface, and its protective performance is crucial to the safety of the pilot during high-altitude flight.

[0003] When pilots ascend or descend rapidly, a series of physiological reactions occur. Rapid changes in altitude interfere with the inner ear's balance mechanism, leading to dizziness, nausea, ear pain, and hearing loss. This can be addressed by pinching the nose, closing the mouth, and gently exhaling to equalize middle ear pressure. However, to meet safety, sealing, and oxygen supply efficiency requirements at high altitudes, aviation oxygen masks typically use a rigid shell. This makes it impossible for pilots to quickly pinch their nose in case of physiological reactions. Furthermore, due to significant differences in facial features (nose bridge height and facial contours), existing oxygen masks cannot perfectly fit everyone's face, resulting in poor sealing and insufficient oxygen concentration. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a low-profile aviation oxygen supply mask body that improves the physiological state at high altitudes, significantly improves the pilot's operational efficiency and physiological comfort in high-altitude environments, conforms to the facial curves, optimizes airflow guidance, and enhances airtightness.

[0005] The purpose of this utility model is achieved through the following technical solution: a low-profile aviation oxygen supply mask body for improving physiological state at high altitudes, comprising inner and outer silicone rubber parts and a mask shell that fit together.

[0006] Silicone rubber components include a mask body that mates with the mask shell and a face mask body that fits into the human face.

[0007] The upper side of the mask shell has a protruding part, and the two sides of the protruding part facing the side end of the mask shell have a side straight inclined part. The protruding part facing the upper end of the mask shell has an upper straight inclined part, and the protruding part facing the lower end of the mask shell has a lower straight inclined part. The two sides of the lower straight inclined part facing the edge of the mask shell have compression holes corresponding to the two sides of the nose wings.

[0008] A further improvement of this utility model is that the mask shell is located at the edge position on both sides of the nose wings in an inwardly curved arc shape.

[0009] A further improvement of this utility model is that: one side of the straight inclined surface has an inhalation valve hole, the other side of the straight inclined surface has an exhalation valve hole, the upper straight inclined surface has a residual pressure interface hole, and the lower straight inclined surface has a communication component mounting hole.

[0010] A further improvement of this utility model is that: the mask fitting body includes a fitting part that cooperates with the mask shell and a supporting connecting part that connects to the face fitting body. There is a groove between the fitting part and the supporting connecting part that accommodates the edge of the mask shell. The supporting connecting part is located at the lower edge of the mask shell and extends outward along the extension direction of the edge of the mask shell.

[0011] A further improvement of this utility model is that the face patch is smoothly bent inward along the edge of the support connection, and the upper inner side of the face patch has an extension that fits against the forehead of the human body.

[0012] A further improvement of this utility model is that the face-fitting body and the mask-fitting body are integrally molded structures, and the hardness of the face-fitting body is less than that of the mask-fitting body.

[0013] This utility model has the following advantages compared with the prior art:

[0014] 1. This utility model has compression holes on both sides of the lower straight sloping face of the mask shell, corresponding to the sides of the nose wings. The two compression holes facilitate the pilot's quick nose pinching at high altitudes, which not only ensures the overall strength of the aviation oxygen supply mask, but also quickly and effectively improves the pilot's operational efficiency and physiological comfort in high-altitude environments. Secondly, the silicone rubber component set on the inner side of the mask shell in this application fits tightly against the human face, ensuring sealing while improving facial contact comfort and meeting the usage needs of different face shapes.

[0015] 2. Because the contour of the human face naturally curves inward from the forehead to the chin, the mask shell is designed with a gradually tapering shape through the inclusion of protruding parts, side straight bevels, upper straight bevels, and lower straight bevels. This design allows for a better fit to the physiological structure of the face. The protruding parts act as reinforcing ribs, resisting deformation of the mask body under external pressure, reducing air leakage, ensuring efficient oxygen input, guiding oxygen directly to the mouth and nose area, reducing turbulence, improving breathing efficiency, and avoiding excessive pressure on the bridge of the nose and cheeks, thus extending wearing time and reducing fatigue.

[0016] 3. The side, upper, and lower straight bevel sections all adopt a straight inward-curving design, which makes it easier to punch holes. At the same time, the straight angular structure can better resist deformation caused by compression or collision. Especially in the harsh environment of aviation lighting, it can maintain a good shape to ensure stable sealing performance. Attached Figure Description

Detailed Implementation

[0024] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0026] In this utility model, unless otherwise explicitly specified and limited, terms such as “connection,” “provided with,” and “have” should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can be described as a mechanical connection, a direct connection, or a connection through an intermediate medium. Those skilled in the art can understand the basic meaning of the above terms in this utility model according to the specific circumstances.

[0027] A low-profile aviation oxygen supply mask body for improving physiological conditions at high altitudes, referring to Figure 1 and Figure 3 It includes a silicone rubber component 1 that is bonded together internally and externally, and a mask housing 2;

[0028] The silicone rubber component 1 includes a mask body 11 that mates with the mask housing 2 and a face body 12 that mates with the human face.

[0029] The upper side of the mask housing 2 has a protruding part 21. The two sides of the protruding part 21 facing the side end of the mask housing 2 have a side straight inclined part 22. The protruding part 21 facing the upper end of the mask housing 2 has an upper straight inclined part 23. The protruding part 21 facing the lower end of the mask housing 2 has a lower straight inclined part 24. The two sides of the lower straight inclined part 24 facing the edge of the mask housing 2 have compression holes 25 corresponding to the two sides of the nose wings.

[0030] This invention features compression holes 25 on both sides of the lower straight inclined face 24, facing the edge of the mask housing 2, corresponding to the sides of the nose. The two compression holes 25 facilitate pilots to quickly pinch their noses at high altitudes, ensuring the overall strength of the aviation oxygen supply mask and effectively improving the pilot's operational efficiency and physiological comfort in high-altitude environments. Secondly, the silicone rubber component 1 on the inner side of the mask housing 2 fits tightly against the human face, ensuring a seal while improving facial contact comfort and meeting the needs of different face shapes.

[0031] Because the contour of the human face naturally curves inward from the forehead to the chin, the mask shell 2 is designed with a gradually tapering shape by setting a protruding part 21, a side straight inclined part 22, an upper straight inclined part 23, and a lower straight inclined part 24. This design can better fit the physiological structure of the human face. Among them, the protruding part 21 acts as a reinforcing rib, which can resist the deformation of the mask body when it is squeezed by external force, reduce air leakage, ensure efficient oxygen input, guide oxygen directly to the mouth and nose area, reduce turbulence, improve breathing efficiency, and at the same time avoid excessive pressure on the bridge of the nose and cheeks, prolong the wearing time, and reduce fatigue.

[0032] Among them, the side straight bevel section 22, the upper straight bevel section 23 and the lower straight bevel section 24 all adopt a straight inward design, which makes it easier to punch holes. At the same time, the straight angular structure can better resist deformation caused by extrusion or collision. Especially in the harsh environment of aviation lights, it can maintain a good shape to ensure stable sealing performance.

[0033] In this embodiment, the mask shell 2 is positioned at the edges on both sides of the nose in an inwardly curved arc shape. The inwardly curved arc shape of the mask shell 2 on both sides of the nose helps the silicone rubber body 1 fit against the human face, reducing ineffective space and improving breathing efficiency.

[0034] In this embodiment, one side of the inclined surface 22 has an inhalation valve hole 26, the other side of the inclined surface 22 has an exhalation valve hole 27, the upper inclined surface 23 has a residual pressure interface hole 28, and the lower inclined surface 24 has a communication component mounting hole 29. The inhalation valve hole 26, the exhalation valve hole 27, the residual pressure interface hole 28, and the communication component mounting hole 29 are all located on the inclined surface to ensure connection stability and connection strength.

[0035] In this embodiment, the mask fitting body 11 includes a fitting part 111 that cooperates with the mask housing 2 and a support connecting part 112 that connects to the face fitting body 12. There is a groove 113 between the fitting part 111 and the support connecting part 112 for the edge of the mask housing 2 to be embedded. The support connecting part 112 is located at the lower edge of the mask housing 2 and extends outward along the extending direction at the edge of the mask housing 2.

[0036] In this embodiment, the face patch 12 is smoothly bent inward along the edge of the support connection portion 112, and the upper inner side of the face patch 12 has an extension portion 121 that fits against the forehead of the human body. The extension portion 121 further increases the contact area between the forehead of the human body and the silicone rubber part 1, ensuring a tight fit.

[0037] In this embodiment, the face-fitting body 12 and the mask-fitting body 11 are integrally formed structures, and the hardness of the face-fitting body 12 is less than that of the mask-fitting body 11.

[0038] The edge of the mask shell 2 is embedded in the groove 113 of the mask fitting body 11. The mask fitting body 11 has a slightly higher hardness, which can effectively support the rigid mask shell 2. The face fitting body 12 has a slightly lower hardness and is more flexible, which improves the comfort of contact with the human face.

[0039] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
