Description

Technical Field

[0001] The utility model particularly relates to a mask supporting frame and a mask which can adapt to facial changes, and belongs to the technical field of protective equipment. Background Art

[0002] Smog is a mixture of fog and haze. Since the core substances of haze are smoke, dust and other substances suspended in the air, it reduces visibility. Moreover, haze can directly enter the nostrils with the gas and adhere to the lower respiratory tract and lung lobes of the human body, thus causing harm to human health.

[0003] Haze weather is primarily caused by human-induced environmental pollution. It typically occurs under natural conditions such as low temperatures and low winds, making it difficult for air pollutants to disperse and linger in a specific area for extended periods. To mitigate the effects of haze on the respiratory system, people wear masks when exercising outdoors or traveling to reduce the inhalation of dust particles. However, ordinary masks do not provide a good seal, allowing tiny pollutant particles to enter the respiratory system through the gap between the mask and the face. Consequently, many masks with high sealing properties have emerged on the market. Patent application number CN03142937.8 discloses a mask with excellent airtightness. The mask comprises a mask body, a face seal, and a frame. The outer edges of the mask body and the face seal are joined together. The face seal is formed by laminating an airtight soft resin onto an elastic fabric made of nylon or polyester fibers. The frame is inserted along the connecting portion between the outer edges of the mask body and the face seal. However, existing mask frames require a certain degree of structural strength to support the mask body and maintain its three-dimensional shape. However, these overly stable frames only maintain a seal with the human face in a specific posture and cannot adapt to facial movements. Utility Model Content

[0004] The main purpose of the utility model is to provide a mask support frame and a mask that can adapt to facial changes, thereby overcoming the shortcomings of the prior art.

Unless otherwise specified, the mask support frame, mask body, facial seal and ear straps that can adapt to facial changes mentioned in the embodiments of the present invention can all be obtained by processing means known in the art, and their specific structures, sizes, etc. are not limited here.

[0031] The embodiment of the present invention provides a mask support frame that can adapt to facial changes and is used to support the mask body. The mask support frame is a three-dimensional structure, which can enable the mask body to present a desired three-dimensional shape.

[0032] In a more specific implementation case, please refer to Figures 1-4The mask support frame that can adapt to facial changes includes: a support ring 100, a main beam 200, a dynamic buffer beam 300 and a plurality of ribs 400. The two ends of the main beam 200 are fixedly connected to the support ring 100. The plurality of ribs 400 are respectively arranged on both sides of the main beam 200. One end of each rib 400 is fixedly connected to one of the support ring 100 and the main beam 200, and the other end is fixedly connected to the other of the support ring 100 and the main beam 200 or another rib 400. 200 and a plurality of the ribs 400 are connected to form a required three-dimensional structure, the main beam 200 includes a plurality of main beam sections 210, the dynamic buffer beam 300 is arranged between two adjacent main beam sections 210 and is fixedly connected to the two main beam sections 210 respectively, wherein the dynamic buffer beam 300 can undergo recoverable deformation along the extension direction of the main beam 200 under the action of external force, and when the support ring 100 is subjected to tension applied from the central area to the peripheral area, the dynamic buffer beam 300 can be compressed along the extension direction of the main beam 100.

[0033] For details, please refer to Figure 3 and Figure 4 The support ring 100 has a fitting surface that contacts the human face (the contact here can be direct contact or indirect contact), and the contour and shape of the fitting surface are adapted to the contour of the human face. Figure 2-Figure 4 The support ring 100 as a whole includes a first support segment 110, a second support segment 120, a third support segment 130 and a fourth support segment 140. The first support segment 110 is adapted to the nose area of ​​the human body, the second support segment 120 and the fourth support segment 140 are adapted to the cheek area of ​​the human body, and the third support segment 130 is adapted to the chin area of ​​the human body. The two ends of the main beam 200 are fixedly connected to the first support segment 110 and the third support segment 130 respectively, and a plurality of ribs 400 are distributed between the main beam 200 and the second support segment 120 and the fourth support segment 140.

[0034] It should be noted that the present invention divides the support ring 100 as a whole into a first support segment 110, a second support segment 120, a third support segment 130 and a fourth support segment 140 arranged along its own circumference. The first support segment 110, the second support segment 120, the third support segment 130 and the fourth support segment 140 can be connected end to end in sequence. Of course, the support ring 100 can also include other functional segments, and the first support segment 110, the second support segment 120, the third support segment 130 and the fourth support segment 140 and other functional segments are fixedly connected.

[0035] Specifically, the support ring 100 is an axisymmetric structure, and the symmetry axis AA of the support ring 100 passes through the two ends of the main beam 200 and the two connection points of the support ring 100, wherein the second support segment 120 and the fourth support segment 140 are axially symmetrically arranged with the symmetry axis AA of the support ring 100 as the axisymmetric axis. More specifically, the first support segment 110 and the third support segment 130 are mirror-symmetrical structures, and their symmetry axes are also the symmetry axes AA. It can be understood that the connection position of the main beam 200 and the first support segment 110 and the third support segment 130 is located in the midpoint area of ​​the first support segment 110 and the third support segment 130.

[0036] It should be noted that the structure of the fitting surface of the support ring 100 adapted to the human facial contour is well known in the art, and its specific contour structure and shape are not limited here.

[0037] Specifically, the main beam 200 as a whole is an arc-shaped structure that bends from the side of the mask support frame facing the human face to the side facing away from the human face. The arc structure of the main beam 200 corresponds to the central axis of the human face. The specific structural parameters of the main beam 200 can be set according to specific needs and are not limited here.

[0038] Specifically, one end of each of the ribs 400 is fixedly connected to one of the support ring 100 and the main beam 200, and the other end is fixedly connected to the other of the support ring 100 and the main beam 200 or another rib 400. More specifically, the multiple ribs 400 located on both sides of the main beam 200 are distributed in a mirror-symmetrical manner. As a preferred structure, the multiple ribs 400 located on both sides of the main beam 200 can be interconnected to form a mesh structure. Specifically, the multiple ribs 400 located on both sides of the main beam 200 are fixedly connected to the second support segment 120 and the fourth support segment 140, and the ribs 400 have no direct contact with the first support segment 110 and the third support segment 130. The multiple ribs 400 can ensure that the mask support frame has good structural stability in the axial direction perpendicular to the central axis of the mask support frame that can adapt to facial changes.

[0039] Specifically, the main beam 200 includes a plurality of main beam sections 210, and the dynamic buffer beam 300 is arranged between two adjacent main beam sections 210 and is fixedly connected to the two main beam sections 210 respectively, wherein the dynamic buffer beam 300 can undergo recoverable deformation along the extension direction of the main beam 200 under the action of external force, and when the support ring 100 is subjected to tension applied from the central area to the peripheral area, the dynamic buffer beam 300 can be compressed along the extension direction of the main beam 200, so that the overall shape of the support ring 100 remains basically constant, and the fitting surface of the support ring 100 always fits with the human face. It should be noted that the tension is mainly applied outward along the axis of symmetry of the support ring. The tension is generally caused when the wearer of the mask including the mask support frame that can adapt to facial changes moves his mouth. For example, when the wearer is speaking, the mask support frame that can adapt to facial changes will be affected by the tension. At this time, the dynamic buffer beam 300 will expand and contract along the extension direction of the main beam 200, thereby ensuring that the posture of the support ring 100 of the mask support frame that can adapt to facial changes remains stable, and thus always maintains a good fit with the human face and maintains a good sealing effect.

[0040] Specifically, the dynamic buffer beam 300 is a zigzag structure extending in a direction from the support ring 100 to the support ring 200. Alternatively, the dynamic buffer beam 300 is a flexible member, or an elastic member. For example, the flexible member may be a silicone member, or the elastic member may be a spring. More specifically, the dynamic buffer beam 300 includes a plurality of buffer beam segments 310 connected end to end, with two adjacent buffer beam segments 310 arranged at an angle. The plurality of buffer beam segments 310 are connected in sequence to form the zigzag structure. More specifically, the buffer beam segments 310 are linear or curved. As a preferred embodiment, the dynamic buffer beam 300 with a zigzag structure may be integrally formed with the main beam 200, that is, the dynamic buffer beam 300 may be formed by zigzagging a portion of the main beam 200. It should be noted that while the dynamic buffer beam 300 shown in the figure is generally S-shaped, it can also have other configurations, such as wavy or broken line shapes, which will not be described in detail here.

[0041] Specifically, the support ring 100, the main beam 200, the dynamic buffer beam 300 and the ribs 400 included in the support frame of the mask that can adapt to facial changes can be fixedly connected by a method known in the art, or they can be integrally arranged. For example, the support ring 100, the main beam 200, the dynamic buffer beam 300 and the plurality of ribs 400 can be integrally formed by 3D printing. Exemplarily, the material of the support frame of the mask that can adapt to facial changes can also be polyolefins such as polyethylene (PE) and its copolymers, including high-density polyethylene (HDPE), medium-density polyethylene (MDPE), low-density polyethylene (LDPE), ultra-low-density polyethylene (ULDPE), polyethylene-α-olefin copolymers, etc., polypropylene (PP) such as polypropylene homopolymer and its copolymers, polycarbonate (PC).

[0042] In a more specific implementation case, a mask includes a mask body, a facial seal, and a mask support frame that can adapt to facial changes. The mask body is covered on the mask support frame that can adapt to facial changes. The outer edge portion of the facial seal is joined to the outer edge portion of the mask body and wraps the outer edge of the mask support frame that can adapt to facial changes. The facial seal is provided with openings corresponding to the human mouth and nose, and ear straps, etc. can be fixed on the mask body.

[0043] Specifically, the face seal is fixed to one side of the mask body by ultrasonic welding (for example, the face seal is fixedly coupled to the inner layer of the mask body). Specifically, the structure of the mask body is a conventional structure known to those skilled in the art, which is known to those skilled in the art and can be produced using existing mask production equipment. It can be a disposable medical surgical mask that complies with the YY0469-2011 standard or a disposable medical mask that complies with the YY / T0969-2013 or GB 15979-2002 standard. For example, the mask body includes an inner layer, a middle layer, and an outer layer arranged in sequence, wherein the middle layer includes at least one layer of meltblown cloth, and the face seal is fixed to the side of the inner layer away from the middle layer by ultrasonic welding. The inner layer and the outer layer can be non-woven fabrics, and their thicknesses, etc. are all in accordance with standard settings. In addition, the mask body also has a folding structure formed by folding at least part of the mask body along its width direction to facilitate the user to pull the mask along the width direction when in use. Specifically, the facial seal includes a veneer layer, a filter layer and a surface layer stacked in sequence. The surface layer is located on the side of the filter layer close to the mask body. The veneer layer can directly fit the human face. The veneer layer and the surface layer are both non-woven fabrics. The filter layer includes a polytetrafluoroethylene filter membrane. The veneer layer, the filter layer and the surface layer are combined into one by bonding or ultrasonic welding; wherein the thickness of the veneer layer is 0.1-2mm, the thickness of the filter layer is 1-500μm, and the thickness of the surface layer is 0.1-2.5mm.

Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention.
