Description

Technical Field

[0001] This utility model relates to the field of protective mask technology, specifically a comfortable medical protective mask. Background Technology

[0002] Since the outbreak of the pandemic, the global cumulative number of confirmed cases has exceeded 700 million. Medical protective masks have become core equipment for blocking the spread of respiratory infectious diseases. In the field of medical protection, correctly wearing a qualified mask can reduce the risk of respiratory virus transmission by 65%-82%. Traditional medical protective masks typically adopt a flat structure design, mainly consisting of the mask body and ear loops. The mask body is usually made of single or multiple layers of material, and the ear loops are used to secure the mask to the face. However, this traditional design has many shortcomings:

[0003] When worn, the mask fits directly against the mouth and nose. When breathing, the inner wall of the mask is prone to friction with the lips and nasal mucosa. Wearing it for a long time can cause skin redness, dryness, or even damage. The sealed space formed by the flat mask and the face is small. When exhaling, hot and humid air accumulates inside the mask, causing the internal temperature to rise and breathing resistance to increase.

[0004] Traditional masks concentrate stress on areas such as the bridge of the nose and behind the ears. Clinical observations show that after prolonged wear, about 45% of users experience tenderness in the bridge of the nose, and 28% experience redness, swelling, and ulceration of the skin behind the ears.

[0005] To ensure protective effectiveness, traditional meltblown fabric filter layers often employ a high-density fiber structure, which leads to increased air permeability resistance. Utility Model Content

[0006] The purpose of this invention is to provide a comfortable medical protective mask to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a comfortable medical protective mask, comprising a mask body, a mask surface, and ear loops. The mask body includes a mask surface and two plastic frames symmetrically arranged on both sides of the mask surface. Both plastic frames have parallel facial plastic support strips fixedly connected to the mask surface on their inner sides. Each of the two plastic frames has an ear loop on one side via a mating protrusion. An adjustment block is installed on the ear loop. The tops of the two ear loops are respectively provided with a first strap and a second strap. The top of the first strap has a buckle, and the top of the second strap has a fixing strip that matches the buckle.

[0008] The mask surface includes an outer protective layer and an inner comfort layer, and an intermediate filter layer is provided between the outer protective layer and the inner comfort layer. The inner comfort layer adopts a three-layer structure, namely a silk protein fiber layer that contacts the skin, an intermediate seaweed fiber moisture-absorbing layer, and a breathable non-woven fabric layer near the intermediate filter layer.

[0009] Preferably, the outer protective layer is composed of a wear-resistant and water-resistant polytetrafluoroethylene (PTFE) film and colored spunbond nonwoven fabric.

[0010] Preferably, the intermediate filter layer comprises nanofiber meltblown fabric and granular activated carbon uniformly disposed inside the nanofiber meltblown fabric.

[0011] Preferably, both plastic frame one and plastic frame two have grooves on their inner sides, and polyurethane foam strips are provided inside both grooves, with the thickness of the polyurethane foam strips being greater than the depth of the grooves.

[0012] Preferably, a shape memory alloy strip is provided at the bridge of the nose on the mask surface, and a silicone sleeve is provided on the inner side of the shape memory alloy strip.

[0013] Preferably, both ends of the hook are provided with a mating buckle, and the inner side of each mating buckle is provided with a mating groove that matches the mating protrusion.

[0014] Preferably, one side of the fixing strip is symmetrically provided with matching Velcro raw hairs and Velcro barbs.

[0015] This invention provides a comfortable medical protective mask, which has the following significant advantages compared with the prior art:

[0016] 1. This invention features two symmetrical plastic frames (frame 1 and frame 2) on both sides of the mask surface, with a facial support strip fixedly connected to the mask surface on its inner side. When unfolded, this creates a three-dimensional space inside the mask surface. This effectively avoids direct contact between the mask surface and the mouth and nose, significantly reducing breathing resistance and stuffiness. Compared to traditional flat masks, this invention provides a more comfortable breathing experience, making it especially suitable for medical personnel and general users who wear masks for extended periods.

[0017] 2. The polyurethane foam strips installed on the inner sides of plastic frames one and two are thicker than the depth of the grooves, effectively cushioning the contact pressure between the plastic frames and facial skin, preventing skin discomfort or pressure marks caused by prolonged wear. These details not only improve wearing comfort but also reduce the risk of skin damage caused by friction.

[0018] 3. This invention features adjustable blocks on the ear loops, allowing the ear loop length to be adjusted according to the user's head size. Furthermore, the design of straps one and two, through the cooperation of the fixing strip and the buckle, assists in securing the mask, further reducing the pressure of the ear loops on the ears. This effectively solves the ear pain problem caused by prolonged wearing of traditional mask ear loops, improving the overall wearing experience.

[0019] 4. This utility model adopts a modular design for the ear loops and mask surface. Through the cooperation of the mating protrusions and the mating buckles, the ear loop module can be easily disassembled and connected with the replaced mask surface module. This not only facilitates the cleaning and disinfection of the mask, but also extends the service life of the mask, reduces the generation of medical waste, and has environmental protection significance.

[0020] 5. The mask features a multi-layered structure consisting of an outer protective layer, a middle filter layer, and an inner comfort layer. The outer protective layer is made of a wear-resistant and water-resistant polytetrafluoroethylene (PTFE) membrane combined with colored spunbond nonwoven fabric, providing strong protective performance. The middle filter layer contains nanofiber meltblown fabric and evenly distributed granular activated carbon, effectively filtering bacteria and viruses and adsorbing harmful gases. The inner comfort layer has a three-layer structure, including a silk protein fiber layer that contacts the skin, a seaweed fiber moisture-absorbing layer, and a breathable nonwoven fabric layer, ensuring both good breathability and enhanced wearing comfort.

[0021] 6. A shape memory alloy strip is placed at the bridge of the nose on the mask, and a silicone sleeve is placed inside it. It can adaptively adjust according to the shape of the user's nose bridge, ensuring a tight fit between the mask and the face, effectively preventing gas leakage, and improving the overall sealing and protective effect of the mask.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] Please see Figure 1-4 An embodiment of this utility model provides a comfortable medical protective mask, including a mask body 1, a mask surface 8, and ear loops 10. The mask body 1 includes the mask surface 8 and plastic frame 1 4 and plastic frame 2 9 symmetrically arranged on both sides of the mask surface 8. The inner sides of plastic frame 1 4 and plastic frame 2 9 are both provided with grooves 2, and polyurethane foam strips 3 are provided inside both grooves 2. The thickness of polyurethane foam strips 3 is greater than the depth of groove 2.

[0030] Both plastic frame 1 (4) and plastic frame 2 (9) have parallel facial plastic support strips 5 that are fixedly connected to the mask face 8.

[0031] A shape memory alloy strip 6 is provided at the bridge of the nose on the mask face 8, and a silicone sleeve 7 is provided on the inside of the shape memory alloy strip 6.

[0032] like Figure 1 As shown, the mask body 1 mainly includes a mask surface 8, a first plastic frame 4, and a second plastic frame 9. The mask surface 8 is made of multi-layer composite material, which has good filtration performance and breathability. The first plastic frame 4 and the second plastic frame 9 are symmetrically arranged on both sides of the mask surface 8 to enhance the overall structural strength and wearing stability of the mask.

[0033] Both plastic frame 1 (4) and plastic frame 2 (9) have grooves 2 on their inner sides. The depth of the grooves 2 is designed to ensure that the polyurethane foam strips 3 can be securely embedded within them. The interior of each groove 2 is lined with a polyurethane foam strip 3, which is greater than the depth of the groove 2, thus providing better cushioning during wear and reducing the pressure of the plastic frames on the face.

[0034] The polyurethane foam strip 3 is made of a highly elastic and breathable material. Its thickness is greater than the depth of the groove 2, ensuring that it can fully fill the groove 2 during wear to form a good sealing effect, while providing a soft touch and improving wearing comfort.

[0035] Both plastic frames 4 and 9 have parallel face support strips 5 on their inner sides, which are fixedly connected to the mask face 8. The function of the support strips 5 is to further enhance the three-dimensional effect of the mask face 8 and ensure sufficient space.

[0036] A shape memory alloy strip 6 is provided at the bridge of the nose on the mask face 8. The shape memory alloy strip 6 has good shape memory function and elasticity, and can adjust to the shape of the bridge of the nose when worn, ensuring a tight fit between the mask and the bridge of the nose. A silicone sleeve 7 is provided on the inside of the shape memory alloy strip 6, which has good softness and sealing properties, and can effectively prevent air from leaking from the bridge of the nose, further improving the protective effect of the mask.

[0037] Both plastic frame 4 and plastic frame 9 have a hanging ear 10 on one side via a mating protrusion 20. An adjustment block 11 is installed on the hanging ear 10. The top of the two hanging ears 10 are respectively provided with a first strap 12 and a second strap 17. The top of the first strap 12 is provided with a buckle 13, and the top of the second strap 17 is provided with a fixing strip 16 that matches the buckle 13.

[0038] The fastening strip 16 has symmetrically arranged matching Velcro raw hairs 14 and Velcro barbs 15 on one side.

[0039] Both ends of the lug 10 are provided with a mating buckle 18, and the inner side of each mating buckle 18 is provided with a mating groove 19 that matches the mating protrusion 20.

[0040] Both plastic frame 4 and plastic frame 9 have a hanging lug 10 on one side via a mating protrusion 20. An adjusting block 11 is mounted on the hanging lug 10. The adjusting block 11 has a sliding structure and its position on the hanging lug 10 can be manually adjusted to accommodate different size connection requirements. The surface of the adjusting block 11 has an anti-slip texture for easy operation.

[0041] The tops of the two loops 10 are respectively provided with a first strap 12 and a second strap 17. Both the first strap 12 and the second strap 17 are made of elastic material and have good elasticity. The top of the first strap 12 is provided with a buckle 13, which is made of metal and has high strength and durability. The top of the second strap 17 is provided with a fixing strip 16 that matches the buckle 13 for easy connection.

[0042] The fastening strip 16 has symmetrically arranged matching hook and loop fasteners 14 and hook and loop fasteners 15 on one side. The arrangement of the hook and loop fasteners 14 and hook and loop fasteners 15 allows the fastening strip 16 to fit tightly against the strap 12, thereby achieving a secure connection.

[0043] Both ends of the lug 10 are provided with a mating buckle 18, and the inner side of each mating buckle 18 is provided with a mating groove 19 that matches the mating protrusion 20. The mating buckle 18 has a snap-on structure, which can be quickly connected and separated from the mating protrusion 20 by pressing. The shape of the mating groove 19 matches the mating protrusion 20 to ensure the stability and accuracy of the connection.

[0044] When it is necessary to connect the lug 10 to the plastic frame 4 and the plastic frame 9, align the mating protrusion 20 with the mating groove 19, press the mating buckle 18, and complete the connection of the plastic frame 4 and the plastic frame 9.

[0045] The mask surface 8 includes an outer protective layer 21 and an inner comfort layer 23. The outer protective layer 21 is made of a wear-resistant and water-resistant polytetrafluoroethylene (PTFE) membrane and colored spunbond nonwoven fabric. The middle filter layer 22 includes nanofiber meltblown fabric and granular activated carbon 221 uniformly disposed inside the nanofiber meltblown fabric.

[0046] An intermediate filter layer 22 is provided between the outer protective layer 21 and the inner comfort layer 23. The inner comfort layer 23 has a three-layer structure, namely a silk protein fiber layer 233 that contacts the skin, a seaweed fiber moisture-absorbing layer 232 in the middle, and a breathable non-woven fabric layer 231 near the intermediate filter layer 22.

[0047] The outer protective layer 21 is composed of a wear-resistant and water-resistant polytetrafluoroethylene (PTFE) membrane and a colored spunbond nonwoven fabric. Specifically, the PTFE membrane has excellent wear resistance and water resistance, effectively blocking the intrusion of external liquids and particles; while the colored spunbond nonwoven fabric provides a good appearance and additional physical protection. The composite structure is formed by hot pressing or adhesive bonding, ensuring the stability and durability of the composite layer.

[0048] The intermediate filter layer 22 is the core component of this invention, comprising nanofiber meltblown fabric and granular activated carbon 221 uniformly disposed within the nanofiber meltblown fabric. The nanofiber meltblown fabric has extremely high filtration efficiency, effectively intercepting fine particulate matter in the air, such as PM2.5. The granular activated carbon 221 has strong adsorption capacity, adsorbing harmful gases and odor molecules in the air, further enhancing the protective performance of the mask.

[0049] The uniform setting of granular activated carbon 221 is achieved by mixing activated carbon granules with nanofiber meltblown fabric during the manufacturing process, ensuring that the activated carbon granules are evenly distributed inside the meltblown fabric, thereby improving the overall filtration effect.

[0050] The inner comfort layer 23 adopts a three-layer structure design, namely the silk protein fiber layer 233 that comes into contact with the skin, the middle seaweed fiber moisture-absorbing layer 232, and the breathable non-woven fabric layer 231 near the middle filter layer 22.

[0051] Silk protein fiber layer 233: This layer comes into direct contact with the user's skin. Silk protein fibers are soft and skin-friendly, which can effectively reduce discomfort when wearing a mask, while also having good breathability.

[0052] Seaweed fiber moisture-absorbing layer 232: Located between silk protein fiber layer 233 and breathable non-woven fabric layer 231, seaweed fiber has good moisture absorption properties and can absorb exhaled moisture to keep the inside of the mask dry and comfortable.

[0053] Breathable nonwoven fabric layer 231: Located near the middle filter layer 22, the main function of this layer is to further ensure the breathability of the mask, and at the same time, it serves as a transition layer between the inner comfort layer and the middle filter layer, ensuring the stability of the overall structure.

[0054] When this application embodiment is used,

[0055] Plastic frames 4 and 9 are placed on both sides of the mask surface 8 and fixed in position using ultrasonic welding. Polyurethane foam strips 3 are embedded in the grooves 2 of plastic frames 4 and 9, with the foam strip thickness exceeding the depth of the grooves 2 to ensure the foam portion is exposed to cushion facial pressure. On the inside of plastic frames 4 and 9, a facial plastic support strip 5 is sewn parallel to the mask surface 8, with both ends welded to the plastic frames to form a three-dimensional support structure, creating a breathing space inside the mask. A shape memory alloy strip 6 is sewn to the nose bridge position of the mask surface 8, with a silicone sleeve 7 wrapped around the inside of the alloy strip and fixed with hot melt adhesive, ensuring the shape memory alloy strip can bend with the shape of the nose bridge and the silicone sleeve conforms to the skin to reduce pressure.

[0056] Weld mating protrusions 20 to the outside of plastic frame 1 (4) and plastic frame 2 (9). Align the mating buckles 18 at both ends of the ear loop 10 with the mating protrusions 20 and press them into the mating grooves 19 to achieve a detachable connection between the ear loop and the plastic frame. Install an adjusting block 11 in the middle of the ear loop 10. The adjusting block 11 can slide along the ear loop. Sew a first strap 12 and a second strap 17 to the top of the ear loop 10. A metal buckle 13 is sewn to the top of the first strap 12. A fixing strip 16 is attached to the top of the second strap 17. The fixing strip 16 has Velcro raw hair 14 and Velcro barbs 15 symmetrically arranged on one side. When in use, the fixing strip 16 is passed through the buckle 13 and then folded back. The Velcro is then glued and fixed to help distribute the pressure on the ear.

[0057] Slide adjustment block 11 to adjust the length of ear loop 10 to fit the head size, ensuring no tightness after wearing. Hold plastic frame 1 4 and plastic frame 2 9, and cover the mouth and nose with the mask surface 8, ensuring that the shape memory alloy strip 6 in the bridge of the nose is aligned with the center line of the bridge of the nose, and the facial plastic support strip 5 naturally conforms to the cheeks. Use your index fingers to press the shape memory alloy strip 6 from the center of the bridge of the nose to both sides, making it conform to the contour of the bridge of the nose, and the silicone sleeve 7 contacts the skin to form an airtight seal. Hang the ear loops 10 on both ears, wrap the straps 1 12 and 2 17 around the head, pass the fixing strip 16 through the buckle 13, fold it back, and then fasten it with the Velcro 14 and Velcro 15, adjusting the tightness to no pressure. When breathing normally, the mask surface 8 should rise and fall slightly with breathing, and the facial plastic support strip 5 should maintain three-dimensional space to prevent the mask from sticking tightly to the mouth and nose.

[0058] When replacing the mask face, discard the old mask face 8. When replacing with a new one, repeat the docking steps to ensure that the docking protrusion 20 and the docking groove 19 are fully engaged.
