Description

Technical Field

[0001] The invention relates to the field of masks, and more particularly to a cordless medical mask with a service life reminder function. Background Art

[0002] The sealing and wearing comfort of traditional protective masks have always been difficult to reconcile. Due to individual differences among users, the bandages are prone to being too tight or too loose. A bandage that is too tight will bring great pressure to the user's ears and face, causing indentations and tissue deformation, and wearing it for a long time will aggravate the pain; a bandage that is too loose will cause a gap between the protective mask and the user's face, making it impossible to form a sealing effect, and harmful gases or pollutants enter the mask through the gaps, thus failing to produce a protective function.

[0003] The wearing structure of ordinary protective masks is mostly ear-hanging or behind-the-head style, and the straps are made of rubber ropes or other elastic thin straps. Users will have disadvantages when wearing such masks - the straps put pressure on the human ears, which is inconvenient for people wearing glasses to wear. There are only four connection points between the bandage and the mask body, which will cause the force points to be too concentrated when worn, and it is easy to leak. In order to improve the leakage situation, people add metal or plastic nose strips to the bridge of the nose of the protective mask to clamp the user's nose bridge, but this itself also brings certain risks of causing personal injury.

[0004] At the same time, the existing masks do not have a service life reminder function. During use, they cannot effectively remind users to replace them, and the safety protection is poor. For this reason, we propose a cordless medical mask with a service life reminder function to solve the above problems. Summary of the invention

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a cordless medical mask with a service life reminder function. The function can be realized through the mutual cooperation between a silicone connecting part with a magnetic suction groove and a sealing frame and a pressing frame with a magnetic suction strip. Compared with the traditional technology, when the present invention is used, it is only necessary to separate the silicone connecting part and the pressing frame, and place the filter core layer at the notch of the silicone connecting part. At this time, the pressing frame is buckled, and the filter core layer can be quickly replaced and installed through the magnetic suction force between the magnetic suction strip and the magnetic suction groove, wherein the filter core layer is a disposable product, and the pressing frame and the silicone connecting part can be disinfected and reused repeatedly, which effectively reduces the manufacturing cost of the mask, avoids waste of resources, has high environmental protection, has market prospects, and is suitable for promotion and application.

[0007] 2. Technical solution

[0008] To solve the above problems, the present invention adopts the following technical solutions.

[0009] A cordless medical mask with a service life reminder function comprises a silicone connecting part, a pressing frame and a filter core layer detachably fixed to the inner side of the silicone connecting part by the pressing frame, a sealing frame is arranged on one side of the silicone connecting part, an adhesive layer is coated on the sealing frame, a notch matching the filter core layer is arranged on the side of the silicone connecting part away from the sealing frame, a magnetic suction groove is arranged in the notch, a magnetic suction strip matching the magnetic suction groove is arranged on one side of the pressing frame, a plurality of support frames and an elastic frame are arranged in sequence on the side of the pressing frame away from the magnetic suction strip, a plurality of ventilation grooves are evenly spaced between the support frame and the elastic frame, the elastic frame is in a bow-shaped structure, the support frame is in a straight structure, two ends of the elastic frame are fixedly connected to one side of the support frame, two liquid storage bins are symmetrically arranged in the support frame, and the liquid storage bins A first elastic plate and a second elastic plate are respectively provided on both sides of the warehouse wall, and the first elastic plate and the second elastic plate are arranged in rotational symmetry. Openings corresponding to the end points of the first elastic plate and the second elastic plate are respectively provided on both sides of the liquid storage warehouse, and an extrusion convex point is fixed on the inner wall of the second elastic plate on the side opposite to the first elastic plate. A bow-shaped liquid channel is provided in the elastic frame, and the bow-shaped liquid channel is connected to the opening of the second elastic plate. The bow-shaped liquid channel is filled with a plurality of magnetic beads. The filter core layer includes an inner non-woven fabric layer, a melt-blown layer and an outer non-woven fabric layer from the inside to the outside. A plurality of color-developing interlayers are provided in the outer non-woven fabric layer, and a plurality of display beads are provided in the color-developing interlayer. Antibacterial fibers are fixed on the circumferential surface of the display beads, and the display beads are suspended and fixed in the color-developing interlayer through the antibacterial fibers.

[0010] The present invention cooperates with the silicone connecting part with the magnetic suction groove and the sealing frame and the pressing frame with the magnetic suction strip. Compared with the traditional technology, when in use, the present invention only needs to separate the silicone connecting part and the pressing frame, and place the filter core layer at the notch of the silicone connecting part. At this time, the pressing frame is buckled, and the filter core layer can be quickly replaced and installed through the magnetic suction force between the magnetic suction strip and the magnetic suction groove. The filter core layer is a disposable product, and the pressing frame and the silicone connecting part can be disinfected and reused repeatedly, which effectively reduces the manufacturing cost of the mask, avoids waste of resources, has high environmental protection, has market prospects, and is suitable for promotion and application.

[0011] Furthermore, the interior of the magnetic beads is a hollow structure, the display beads are iron beads, the buoyancy of the magnetic beads in the liquid is greater than their own gravity, and the adsorption force of the magnetic beads on the display beads is greater than the traction force of the antibacterial fiber on the display beads.

[0012] Furthermore, the outer wall of the display bead is coated with a coating that is easy to observe, and the outer wall of the display bead is provided with trivalent iron ions.

[0013] By setting an appropriate amount of trivalent iron ions on the outer wall of the display beads, when part of the water vapor produced by the user's exhalation comes into contact with the trivalent iron ions through the outer non-woven fabric layer, the iron hydroxide colloid produced by the hydrolysis of water and trivalent iron ions has an adsorption effect and can adsorb the particles passing through the outer non-woven fabric layer, further improving the filtering performance of the mask.

[0014] Furthermore, the horizontal height of the middle part of the arcuate liquid channel is higher than the horizontal heights of both ends thereof, and the inner diameter of the arcuate liquid channel is larger than the outer diameter of the magnetic beads.

[0015] Furthermore, the liquid storage tank is filled with a water-absorbing sponge, and the water-absorbing sponge is an antibacterial sponge structure.

[0016] The suspended display beads are connected by antibacterial fibers, and the coating color of the display beads can be observed on the outside of the outer non-woven fabric layer. Under long-term breathing, the water vapor collected in the liquid storage tank is pushed to the bow-shaped liquid channel for accumulation, which causes the liquid level on both sides of the bow-shaped liquid channel to gradually rise. When the liquid level rises to the top of the middle of the bow-shaped liquid channel, the magnetic beads use their own buoyancy to follow the rise of the liquid level and accumulate in the middle of the bow-shaped liquid channel. Since the elastic frame has a bow-shaped structure, the middle of the elastic frame is closest to the filter element layer. At this time, the magnetic force of the magnetic beads accumulated in the bow-shaped liquid channel reaches the maximum, and then the display beads will be adsorbed to overcome the traction force of the antibacterial fiber and approach the magnetic beads and move away from the outside of the outer non-woven fabric layer. Due to the light transmittance of the outer non-woven fabric layer, the display beads will no longer show color after moving away from the outside of the non-woven fabric layer, which can intuitively remind the user that the service life of the filter element layer has reached the maximum and needs to be replaced.

[0017] Furthermore, a mutual magnetic attraction force is provided between the magnetic attraction groove and the magnetic attraction strip, a convex edge is provided on one side of the magnetic attraction strip, and a groove matching the convex edge is provided on the magnetic attraction groove.

[0018] Furthermore, the sealing frame is an elastic frame structure customized according to the facial contour of the user, and a plurality of suction cup structures are provided on the side of the sealing frame that contacts the user's face.

[0019] Furthermore, the adhesive layer is medical silicone gel.

[0020] Through the sealing frame with a suction cup structure and the adhesion layer structure of medical silicone gel, the position where the sealing frame contacts the user's face adopts two adsorption methods: vacuum adsorption of the node by the suction cup and adhesive adsorption of the medical silicone gel. On the one hand, the structural strength of the connection is improved. On the other hand, the medical silicone gel has antibacterial and breathable functions and strong skin-friendliness, which makes it less likely for the user's face to contact with discomfort. At the same time, the sealing frame is an elastic frame structure customized according to the user's facial contour. It is highly tight to wear and not easy to produce wearing gaps. Compared with traditional medical masks, it has more airtightness and effectively improves the protective performance of the mask. At the same time, it adopts a cordless connection method, which is not easy to generate traction on the wearer's ears, avoids the feeling of being strangled when wearing on the ears, and further improves the wearing comfort.

[0021] Furthermore, the second elastic plate has an elastic force close to its opening, and the first elastic plate has an elastic force away from its opening.

[0022] Furthermore, when the elastic frame is compressed, the connection node between the elastic frame and the support frame is deformed, driving the end point of the second elastic plate away from its opening, and using the extrusion protrusion to press the end point of the first elastic plate close to its opening.

[0023] Through the structural design of the liquid storage tank with the first elastic plate and the second elastic plate, when the user exhales, the exhaled air pressure pushes the filter element layer outward, and the elastic frame does not deform. At this time, most of the water vapor exhaled by the user enters the liquid storage tank through the opening at the end of the first elastic plate and is absorbed by the water-absorbing sponge. When the user inhales, the inhaled air pressure absorbs the filter element layer inward, and the elastic frame is deformed at this time. The end of the second elastic plate is affected by the node deformation of the elastic frame and moves away from its opening to open it. At this time, the extrusion convex point of the second elastic plate is deformed and displaced, which squeezes the first elastic plate on the one hand to close the opening at its end point, and squeezes the adsorbed water in the water-absorbing sponge into the bow-shaped liquid channel on the other hand. By cooperating with the user's breathing action, the water vapor in the mask can be automatically adsorbed to the liquid storage tank, which can effectively prevent the filter element layer from being affected by water vapor and reducing the filtering performance.

[0024] 3. Beneficial effects

[0025] Compared with the prior art, the advantages of the present invention are:

[0026] (1) This solution uses the mutual cooperation between the silicone connecting part with a magnetic suction groove and a sealing frame and the pressing frame with a magnetic suction strip. Compared with the traditional technology, when using the present invention, it is only necessary to separate the silicone connecting part and the pressing frame, place the filter element layer on the notch of the silicone connecting part, and then snap the pressing frame together. The filter element layer can be quickly replaced and installed through the magnetic attraction between the magnetic suction strip and the magnetic suction groove. The filter element layer is a disposable product, and the pressing frame and the silicone connecting part can be disinfected and reused repeatedly, which effectively reduces the manufacturing cost of the mask, avoids waste of resources, is highly environmentally friendly, has market prospects, and is suitable for promotion and application.

[0027] (2) Through the structural design of the liquid storage tank with the first elastic plate and the second elastic plate, when the user exhales, the exhaled air pressure pushes the filter element layer outward, and the elastic frame does not deform. At this time, most of the water vapor exhaled by the user enters the liquid storage tank through the opening at the end of the first elastic plate and is absorbed by the water-absorbing sponge. When the user inhales, the inhaled air pressure absorbs the filter element layer inward, and the elastic frame is deformed. The end of the second elastic plate is affected by the node deformation of the elastic frame and moves away from its opening to open it. At this time, the extrusion convex point of the second elastic plate is deformed and displaced. On the one hand, it squeezes the first elastic plate to close the opening at its end point, and on the other hand, it squeezes the adsorbed water in the water-absorbing sponge into the arch-shaped liquid channel. By cooperating with the user's breathing action, the water vapor in the mask can be automatically adsorbed to the liquid storage tank, which can effectively prevent the filter element layer from being affected by water vapor and reducing the filtering performance.

[0028] (3) The suspended indicator beads are connected by antibacterial fibers, and the coating color of the indicator beads can be observed on the outside of the outer non-woven fabric layer. Under the action of long-term breathing, the water vapor collected in the liquid storage tank is pushed to the bow-shaped liquid channel for accumulation, which causes the liquid level on both sides of the bow-shaped liquid channel to gradually rise. When the liquid level rises to the top of the middle of the bow-shaped liquid channel, the magnetic beads use their own buoyancy to follow the liquid level rise and accumulate in the middle of the bow-shaped liquid channel. Since the elastic frame has a bow-shaped structure, the middle of the elastic frame is closest to the filter layer. At this time, the magnetic force of the magnetic beads accumulated in the bow-shaped liquid channel reaches the maximum, and then the indicator beads will be adsorbed to overcome the traction force of the antibacterial fiber and approach the magnetic beads and move away from the outside of the outer non-woven fabric layer. Due to the light transmittance of the outer non-woven fabric layer, the indicator beads will no longer show color after moving away from the outside of the non-woven fabric layer, which can intuitively remind the user that the service life of the filter layer has reached its maximum and needs to be replaced.

[0029] (4) By setting an appropriate amount of trivalent iron ions on the outer wall of the display bead, when part of the water vapor generated by the user's exhalation comes into contact with the trivalent iron ions through the outer non-woven fabric layer, the iron hydroxide colloid produced by the hydrolysis of water and trivalent iron ions has an adsorption effect and can adsorb particles passing through the outer non-woven fabric layer, further improving the filtering performance of the mask.

[0030] (5) Through the sealing frame with a suction cup structure and the adhesive layer structure of medical silicone gel, the position where the sealing frame contacts the user's face adopts two adsorption methods: vacuum adsorption of the node by the suction cup and adhesive adsorption of the medical silicone gel. On the one hand, the structural strength of the connection is improved. On the other hand, the medical silicone gel has antibacterial and breathable functions and strong skin-friendliness, which makes it less likely for the user's face to contact with discomfort. At the same time, the sealing frame is an elastic frame structure customized according to the user's facial contour. It is highly tight to wear and not easy to produce wearing gaps. Compared with traditional medical masks, it has better airtightness and effectively improves the protective performance of the mask. At the same time, it adopts a cordless connection method, which is not easy to generate traction on the wearer's ears, avoiding the feeling of being squeezed by the ears, and further improving the wearing comfort.

Openings corresponding to the endpoints of the first elastic plate 441 and the second elastic plate 442 are respectively provided on both sides of the liquid storage tank 45. An extrusion protrusion 443 is fixed on the inner wall of the second elastic plate 442 opposite to the first elastic plate 441. An arch-shaped liquid channel 431 is provided in the elastic frame 43. The arch-shaped liquid channel 431 is connected to the opening of the second elastic plate 442. A plurality of magnetic beads 5 are filled in the arch-shaped liquid channel 431. The filter element layer 3 includes an inner non-woven fabric layer 31, a melt-blown layer 32 and an outer non-woven fabric layer 33 from the inside to the outside. A plurality of color-developing interlayers 331 are provided in the outer non-woven fabric layer 33. A plurality of display beads 6 are provided in the color-developing interlayer 331. Antibacterial fibers 61 are fixed to the circumferential surface of the display beads 6. The display beads 6 are suspended and fixed in the color-developing interlayer 331 through the antibacterial fibers 61.

[0049] The present invention cooperates with the silicone connecting part 2 with the magnetic suction groove 21 and the sealing frame 1 and the pressing frame 4 with the magnetic suction strip 41. Compared with the traditional technology, when in use, the present invention only needs to separate the silicone connecting part 2 and the pressing frame 4, and place the filter core layer 3 at the notch of the silicone connecting part 2. At this time, the pressing frame 4 is buckled, and the filter core layer 3 can be quickly replaced and installed through the magnetic suction force between the magnetic suction strip 41 and the magnetic suction groove 21. The filter core layer 3 is a disposable product, and the pressing frame 4 and the silicone connecting part 2 can be disinfected and reused repeatedly, which effectively reduces the manufacturing cost of the mask, avoids waste of resources, has high environmental protection, has market prospects, and is suitable for promotion and application.

[0050] The second elastic plate 442 has an elastic force close to its opening, and the first elastic plate 441 has an elastic force away from its opening. When the elastic frame 43 is under pressure, the connection node between the elastic frame 43 and the support frame 44 is deformed, driving the end point of the second elastic plate 442 away from its opening, and utilizing the extrusion protrusion 443 to press the end point of the first elastic plate 441 close to its opening. The liquid storage tank 45 is filled with a water-absorbing sponge, and the water-absorbing sponge is an antibacterial sponge structure.

[0051] Through the structural design of the liquid storage tank 45 with the first elastic plate 441 and the second elastic plate 442, when the user exhales, the exhaled air pressure pushes the filter element layer 3 outward, and the elastic frame 43 does not deform. At this time, most of the water vapor exhaled by the user enters the liquid storage tank 45 through the opening at the end of the first elastic plate 441 and is absorbed by the water absorbent sponge. When the user inhales, the inhaled air pressure absorbs the filter element layer 3 and pushes it inward. At this time, the elastic frame 43 is deformed, and the end of the second elastic plate 442 is affected by the node deformation of the elastic frame 43 and moves away from its opening to open it. At this time, the squeezing convex point 443 of the second elastic plate 442 is deformed and displaced, squeezing the first elastic plate 441 to close the opening at its end point on the one hand, and squeezing the adsorbed water in the water absorbent sponge into the bow-shaped liquid channel 431 on the other hand. By cooperating with the user's breathing action, the water vapor in the mask can be automatically adsorbed to the liquid storage tank 45, which can effectively prevent the filter element layer 3 from being affected by water vapor and reducing the filtering performance.

[0052] The interior of the magnetic bead 5 is a hollow structure, and the display bead 6 is an iron bead structure. The buoyancy of the magnetic bead 5 in the liquid is greater than its own gravity. The adsorption force of the magnetic bead 5 on the display bead 6 is greater than the traction force of the antibacterial fiber 61 on the display bead 6. The outer wall of the display bead 6 is coated with a coating for easy observation. The outer wall of the display bead 6 is provided with trivalent iron ions. The middle horizontal height of the bow-shaped liquid channel 431 is higher than the horizontal heights of its two ends. The inner diameter of the bow-shaped liquid channel 431 is greater than the outer diameter of the magnetic bead 5.

[0053] The suspended display beads 6 are connected by antibacterial fibers 61, and the coating color of the display beads 6 can be observed on the outside of the outer non-woven fabric layer 33. Under the action of long-term breathing, the water vapor collected in the liquid storage tank 45 is pushed to the arcuate liquid channel 431 for accumulation, thereby causing the liquid level on both sides of the arcuate liquid channel 431 to gradually rise. When the liquid level rises to the middle top of the arcuate liquid channel 431, the magnetic beads 5 use their own buoyancy to follow the liquid level rise and accumulate in the middle of the arcuate liquid channel 431. 3 is an arch-shaped structure, and the middle part of the elastic frame 43 is closest to the filter core layer 3. At this time, the magnetic force of the magnetic beads 5 accumulated in the arch-shaped liquid channel 431 reaches the maximum, and then the display beads 6 are adsorbed to overcome the traction force of the antibacterial fiber 61 and approach the magnetic beads 5 and move away from the outside of the outer non-woven fabric layer 33. Due to the light transmittance of the outer non-woven fabric layer 33, the display beads 6 will no longer show color after moving away from the outside of the non-woven fabric layer 33, thereby intuitively reminding the user that the service life of the filter core layer 3 has reached the maximum and needs to be replaced.

[0054] By setting a proper amount of trivalent iron ions on the outer wall of the display bead 6, when part of the water vapor generated by the user's exhalation comes into contact with the trivalent iron ions through the outer non-woven fabric layer 33, the iron hydroxide colloid produced by the hydrolysis of water and trivalent iron ions has an adsorption effect and can adsorb the particles passing through the outer non-woven fabric layer 33, thereby further improving the filtering performance of the mask.

[0055] There is a mutual magnetic attraction force between the magnetic suction groove 21 and the magnetic suction strip 41, a convex edge is provided on one side of the magnetic suction strip 41, and a groove matching the convex edge is provided on the magnetic suction groove 21. The sealing frame 1 is an elastic frame structure customized according to the facial contour of the user. A plurality of suction cup structures are provided on the side of the sealing frame 1 that contacts the user's face, and the adhesive layer is medical silicone gel.

[0056] Through the sealing frame 1 with a suction cup structure and the adhesive layer structure of medical silicone gel, the position where the sealing frame 1 contacts the user's face adopts two adsorption methods: vacuum adsorption of the node by the suction cup and adhesive adsorption of the medical silicone gel. On the one hand, the structural strength of the connection is improved. On the other hand, the medical silicone gel has antibacterial and breathable functions and strong skin-friendliness, which makes it less likely for the user's face to contact with discomfort. At the same time, the sealing frame 1 is an elastic frame structure customized according to the user's facial contour. It is highly tight to wear and not easy to produce wearing gaps. Compared with traditional medical masks, it has more airtightness and effectively improves the protective performance of the mask. At the same time, it adopts a cordless connection method, which is not easy to generate traction on the wearer's ears, avoids the feeling of being strangled when wearing on the ears, and further improves the wearing comfort.

[0057] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
