Description

Technical Field

[0001] The present invention relates to the technical field of nursing and protective products, in particular to an intelligent pressure-dividing breathing mask structure with a multi-segment elastic sealing ring. Background Art

[0002] As a key isolation device between the human body and the external environment, the core function of a respirator is to maintain internal pressure stability through a sealing structure while ensuring user comfort. In existing technologies, the sealing performance of respirators primarily relies on a single-layer or double-layer integrated silicone sealing ring, which elastically deforms to conform to the facial contours. While this design can achieve basic sealing, it suffers from the following significant drawbacks: Insufficient adaptability: The material hardness and deformation range of the integrated sealing ring are fixed, making it difficult to adapt to the facial features of different users (such as nose bridge height, cheekbone protrusion, etc.), which can easily lead to local air leakage or compressive pain, and poor comfort when worn for a long time.

[0003] Uneven pressure distribution: Traditional masks distribute air pressure evenly, failing to dynamically adjust to the varying pressure tolerances of different facial regions (such as the nose and jaw). High-pressure areas can easily cause skin redness and swelling, while low-pressure areas can lead to air leaks, compromising treatment and protection.

[0004] Lack of intelligence: Existing masks mostly rely on external equipment (such as ventilators) to adjust the overall air pressure. They lack real-time monitoring and feedback of the sealing status and are unable to actively optimize pressure distribution or warn of leakage risks. Summary of the Invention

[0005] In view of this, the present invention provides a breathing mask that can dynamically adjust the sealing pressure distribution, adapt to facial contours and has intelligent leakage compensation, so as to solve the problems of insufficient sealing, comfort and intelligence of traditional masks.

[0006] The present invention is achieved through the following technical solutions: The intelligent pressure-dividing breathing mask structure of the multi-segment elastic sealing ring includes: Mask body, segmented sealing frame, intelligent partial pressure adjustment system and micro-groove array; The segmented sealing frame includes a nose bridge sealing ring, a cheekbone sealing ring, and a mandibular sealing ring. The nose bridge sealing ring is made of 25A Shore hardness silicone material, the cheekbone sealing ring is made of 35 Shore hardness silicone material, and the mandibular sealing ring is made of 45A Shore hardness silicone material. A honeycomb micro-airbag structure is provided inside each sealing ring. When the micro-airbag structure is compressed, it generates a deformation of ±1.5mm to compensate for differences in facial contours. The intelligent partial pressure regulating system comprises 8-16 groups of piezoresistive sensors embedded inside the sealing ring, 2-5 groups of independent micro air pumps and a solenoid valve control module, wherein the sensors monitor the contact pressure of each area in real time and feed back to the air pump (32), thereby stabilizing the total pressure at 4-20 cmH2O by regulating the internal pressure of the sealing ring; The micro-groove array is molded on the contact surface of the sealing ring and consists of a V-shaped symmetrical groove (41) and a rib-groove structure arranged in a manner similar to shark skin scales. The V-shaped symmetrical groove (41) has a height of 0.2-0.5 mm and a spacing of 50-200 μm. The rib-groove structure has a rib spacing of 0.1-0.3 mm and a groove depth of 0.05-0.15 mm, forming a multi-level guide channel and an antibacterial barrier.

[0007] The nose bridge area sealing ring, cheekbone area sealing ring and mandibular area sealing ring of the segmented sealing frame are integrally formed by gradient modulus silicone material, and flexible hinges are provided between each sealing ring to allow adjacent areas to produce ±5° relative deflection.

[0008] The honeycomb micro-airbag structure is composed of hexagonal units, and the volume of a single airbag is 0.05-0.2 mL. When under pressure, the leakage is controlled to below 15 mL / min through directional deformation.

[0009] The detection accuracy of the piezoresistive sensor is ±0.54-20 cmH2O, and each group of piezoresistive sensors (31) is linked to the corresponding micro air pump through a PID algorithm closed loop, with a response time of ≤0.1s.

[0010] The mask body and the breathing tube are connected with double insurance by magnetic coupling and rotating buckle. The separation force of the magnetic coupling is ≥15N, and the locking angle of the rotating buckle is 30°±2°.

[0011] The support frame of the mask body is made of a composite of nickel-titanium memory alloy wire and thermoplastic polyurethane (TPU), with a bending angle of ±30° and adaptable to facial contours with a curvature radius of 50-150mm.

[0012] The V-shaped symmetrical grooves of the micro-groove array are orthogonally superimposed on the rib-groove structure arranged in an arrangement imitating shark skin shield scales, forming a physical antibacterial layer with a surface contact area reduced by more than 90%.

[0013] The intelligent partial pressure regulation system also includes a wireless transmission module for uploading pressure data to an external terminal in real time and receiving remote control instructions to adjust the flow parameters of the micro air pump.

[0014] The beneficial effects of the present invention are: The present invention adopts a segmented sealing frame with different hardness, so that the contact pressure with the face is more adapted to the facial features of the human body, while ensuring the sealing effect and improving the comfort; at the same time, the present invention adopts an internal honeycomb micro-airbag structure, and produces a deformation of ±1.5mm when under pressure to compensate for the differences in facial contours, thereby further improving the comfort and adaptability; in addition, the intelligent partial pressure adjustment system is used to monitor the pressure of the segmented sealing frame in real time and make targeted fine-tuning, so as to realize intelligent and precise adjustment of the contact pressure. Finally, the micro-groove array contact surface is used to isolate bacteria, prevent the invasion of external pathogens, and prevent the escape of pathogens brought by the patient, thereby further improving the safety of the present invention.

[0015] In summary, the present invention solves the problems of insufficient sealing, comfort and intelligence of traditional masks by improving the sealing, comfort and intelligence of the mask, and comprehensively improves the safety, comfort and convenience of using the breathing mask.

DETAILED DESCRIPTION

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0020] like Figure 1-6 As shown, an embodiment of the present invention provides: an intelligent pressure-dividing breathing mask structure with a multi-segment elastic sealing ring, which includes: a mask body 1, a segmented sealing frame 2, an intelligent pressure-dividing adjustment system 3 and a micro-groove array 4, specifically: The segmented sealing frame 2 is located on the inner side of the mask, and specifically includes a sealing ring 21 in the nasal bridge area, a sealing ring 22 in the zygomatic area, and a sealing ring 23 in the mandibular area. Each sealing ring is made of silicone material with a Shore hardness of 25A, 35A, and 45A, respectively. That is, the Shore hardness of the sealing ring 21 in the nasal bridge area is 25A, the Shore hardness of the sealing ring 22 in the zygomatic area is 35A, and the Shore hardness of the sealing ring 23 in the mandibular area is 45A. This allows each area to have its own adaptive hardness, adapting to the morphology of the respective area, greatly improving adaptability; In particular, a honeycomb micro-airbag structure 24 is provided inside the segmented sealing frame 2. The micro-airbag structure 24 can change the pressure condition, preferably generating a deformation of ±1.5mm to compensate for differences in facial contours. This is specifically controlled by an intelligent partial pressure adjustment system. The intelligent partial pressure regulation system 3 of this embodiment includes 8-16 groups of piezoresistive sensors 31 embedded inside the sealing ring, 2-5 groups of independent micro air pumps 32 and a solenoid valve control module 33. The piezoresistive sensors 31 monitor the contact pressure of each area in real time and feed back to the micro air pump 32. By adjusting the internal pressure of the sealing ring, the total pressure is stabilized within the range of 4-20 cmH2O, so that the pressure is intelligently controlled, ensuring a sealed state and comfort under any circumstances. To reduce weight, this embodiment can try to adopt lighter sensors and micro air pumps. Their models and specifications are not limited and can be selected according to existing actual lightweight manufacturing capabilities. For example, the sensor uses a Kulite pressure sensor, some models of which weigh less than 0.2 grams and are suitable for use in confined space environments. The air pump uses a Wildflow Pump lightweight air pump, which weighs only 17 grams, thereby reducing the overall weight of the mask and improving comfort.

[0021] In particular, in order to improve safety, this embodiment provides a micro-groove array 4 in the sealing ring contact area. The micro-groove array 4 is molded on the sealing ring contact surface and consists of a V-shaped symmetrical groove 41 and a rib-groove structure 42 arranged like shark skin scales. More preferably, the V-shaped symmetrical groove 41 has a height of 0.2-0.5 mm and a spacing of 50-200 μm. The ribs 43 of the rib-groove structure 42 have a spacing of 0.1-0.3 mm and a depth of 0.05-0.15 mm. The criss-crossing ribs and the V-shaped symmetrical grooves 41 form a multi-level diversion channel and an antibacterial barrier.

[0022] This embodiment adopts a segmented sealing frame 2 with different hardness, so that the contact pressure with the face is more adapted to the facial features of the human body, while ensuring the sealing effect and improving the comfort; at the same time, this embodiment adopts an internal honeycomb micro-airbag structure 24, and produces a deformation of ±1.5mm when under pressure to compensate for the difference in facial contours, thereby further improving the comfort and adaptability; in addition, the intelligent partial pressure adjustment system 3 is used to monitor the pressure of the segmented sealing frame 2 in real time and make targeted fine-tuning to achieve intelligent and precise adjustment of the contact pressure. Finally, the micro-groove array contact surface is used to isolate bacteria, prevent the invasion of external pathogens, and prevent the escape of pathogens brought by the patient, thereby further improving the safety of the present invention.

[0023] In summary, this embodiment comprehensively improves the safety, comfort and ease of use of the breathing mask by improving the sealing, comfort and intelligence of the mask.

[0024] As an improvement of this embodiment, the nose bridge area sealing ring 21, the zygomatic area sealing ring 22 and the mandibular area sealing ring 23 of the segmented sealing frame 2 are all integrally formed by gradient modulus silicone injection molding, and the contact areas with the zygomatic bone, nose bridge and mandibular are provided with corresponding outer contours to reduce the deformation of the internal airbag during use. In particular, a flexible hinge 25 is provided between the sealing rings in adjacent areas, allowing adjacent areas to produce a relative deflection of ±5°. This structure makes the connection between the various areas more natural, and can also adapt to various external forces. It can ensure the sealing of the internal space and prevent the invasion of bacteria or the escape of pathogens under any circumstances, further improving the safety during use and avoiding the risk of cross infection.

[0025] As an improvement to this embodiment, the honeycomb micro-airbag structure 24 is composed of hexagonal units, with a single airbag volume of 0.05-0.2 mL. When pressurized, it deforms in a directional manner, controlling leakage to below 15 mL / min. Multiple independent honeycomb micro-airbag structures 24 allow for both shape adjustment and control over the range and size of adjustment, ensuring reliable and effective regulation.

[0026] As an improvement to this embodiment, the piezoresistive sensors 31 have a detection accuracy of ±0.54-20 cmH2O. Each set of piezoresistive sensors 31 and the corresponding micro air pump 32 operate in a closed-loop PID algorithm, with a response time of ≤0.1s. This enables timely and accurate response to any situation, ensuring sealing capability at all times.

[0027] As an improvement to this embodiment, the mask body 1 and the breathing tube 5 are connected using a dual-safety mechanism: a magnetic coupling 51 and a rotating buckle 52. The separation force of the magnetic coupling 51 is ≥ 15N, and the locking angle of the rotating buckle 52 is 30°±2°. This further enhances the convenience and speed of operation.

[0028] As an improvement of this embodiment, the support frame 11 of the mask body 1 is made of a composite of nickel-titanium memory alloy wire 111 and thermoplastic polyurethane TPU, and can be bent at an angle of ±30° to adapt to facial contours with a curvature radius of 50-150 mm.

[0029] As an improvement to this embodiment, the V-shaped, symmetrical grooves 41 of the microgroove array 4 are orthogonally superimposed with a rib-groove structure 42 that mimics the scales of shark skin. The longitudinal ribs 43 are spaced 0.1-0.3 mm apart, and the transverse grooves 44 are 0.05-0.15 mm deep. This creates a multi-level diversion channel, reducing secretion retention. By disrupting bacterial biofilm formation, experimental data demonstrates a significant inhibition of E. coli attachment.

[0030] As an improvement to this embodiment, the intelligent partial pressure regulating system 3 further includes a wireless transmission module 34 for uploading pressure data to an external terminal in real time and receiving remote control instructions to adjust flow parameters of the air pump 32 .

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
