Description

Technical Field

[0001] The present invention relates to the technical field of masks, and in particular to an antibacterial and warm-keeping mask and its production process. Background Art

[0002] A mask is a sanitary product, generally referring to a product worn over the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, droplets, viruses and other substances, and is made of gauze, paper, etc. The mask has a certain filtering effect on the air entering the lungs. Wearing a mask is very useful during the epidemic of respiratory infectious diseases and when working in a polluted environment such as dust.

[0003] In the prior art, in order to conveniently fix the mask on the face, a nose bridge strip is usually pasted on the upper edge of the mask. By deforming the nose bridge strip, the mask is deformed to make the mask fit the nose wings, preventing the mask from dropping.

[0004] However, this method is only applicable to the case where the mask is relatively thin. For a warm-keeping mask, in order to ensure its warm-keeping performance, it is usually relatively thick. When using the nose bridge strip to drive the mask to deform, due to the relatively thick mask, it is difficult to make the mask fit the nose wings completely. As a result, cold air is likely to directly enter the mask from the gap between the mask and the nose wings, which not only affects the dust-proof effect of the mask, but also affects the warm-keeping effect of the mask. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the first object of the present invention is to provide an antibacterial and warm-keeping mask.

[0006] The above invention object of the present invention is achieved by the following technical solutions:

[0007] An antibacterial and warm-keeping mask, comprising a left piece and a right piece connected to the left piece. A connecting piece buckled on the nose bridge is arranged between the left piece and the right piece. The left piece and the right piece are rotatably connected through the connecting piece. A bent portion fitting the nose bridge is arranged on the inner side of the connecting piece. Hanging straps are arranged on both the left piece and the right piece.

[0008] By adopting the above technical solutions, the left piece and the right piece are connected through the connecting piece. The bent portion is arranged on the connecting piece and fits the nose bridge, so that after wearing the antibacterial and warm-keeping mask, the antibacterial and warm-keeping mask is relatively sealed with the face. The left piece and the right piece are separately arranged, and the overall fit of the mask with the face can be realized by adjusting the shape and angle of the connecting piece itself, thus avoiding the problem of poor fit between the mask and the face caused by the relatively large thickness of the mask. The dust-proof, antibacterial and warm-keeping effects of the mask are ensured.

[0009] Preferably, the connecting piece includes a fixing part at the upper part and a breathing part at the lower part. The fixing part includes a fixing layer, a deformation layer arranged inside the fixing layer, and an elastic layer arranged between the fixing layer and the deformation layer. The elastic modulus of the fixing layer is greater than that of the deformation layer.

[0010] By adopting the above technical solution, an elastic layer is arranged between the fixing layer and the deformation layer. After the elastic layer is extruded by squeezing the deformation layer and the fixing layer, the elastic layer undergoes elastic deformation. After recovery, since the elastic modulus of the fixing layer is greater than that of the deformation layer, under the action of the elastic layer, the deformation layer is extruded by the elastic layer and thus moves away from the fixing layer. When a person wears the mask, the hand squeezes the connecting piece to make the connecting piece fit as closely as possible to the bridge of the nose and the nose wings. At this time, the elastic layer undergoes elastic deformation. After letting go, the elastic layer recovers, so that the deformation layer has a tendency to move towards the bridge of the nose and the nose wings, thereby further improving the fit between the antibacterial and warm-keeping mask and the human face.

[0011] Preferably, a support strip is arranged on the side of the fixing layer away from the deformation layer, a protective layer is arranged on the outer side of the fixing layer, and a support groove for embedding the support strip is formed on the protective layer.

[0012] By adopting the above technical solution, through the arrangement of the support strip, the structural strength of the fixing layer is enhanced, thereby improving the anti-deformation ability of the fixing layer. Therefore, when the elastic layer squeezes the fixing layer and the deformation layer, the deformation amount of the deformation layer is much larger than that of the fixing layer, improving the fit effect between the connecting piece and the human face. At the same time, through the cooperation of the support strip and the support groove, the protective layer arranged outside the fixing layer is limited, improving the tightness of the connection between the protective layer and the fixing layer.

[0013] Preferably, a skin-friendly layer is arranged inside the deformation layer, and fixing films are arranged on both the upper edge and the lower edge of the skin-friendly layer away from the deformation layer.

[0014] By adopting the above technical solution, through the arrangement of the skin-friendly layer, the comfort of the mask is improved. The fixing film has good adhesion to the skin. Therefore, through the arrangement of the fixing film, the inner edge of the mask can fit better with the human face. After wearing the mask, a relatively airtight space can be formed between the mask and the human face covered by the mask, and the outside air cannot directly enter the nasal cavity and oral cavity of the human body through the mask.

[0015] Preferably, a deformation groove is formed on the side of the fixing film away from the deformation layer.

[0016] By adopting the above technical solution, when wearing the mask, by squeezing the mask, the deformation groove undergoes a certain deformation, and the air in the deformation groove is extruded. After releasing, a negative pressure space is formed between the skin and the deformation groove, so that the fixing film is adsorbed on the skin, improving the fit between the mask and the skin.

[0017] Preferably, air guiding grooves are formed on the inner sides of the left piece and the right piece, and the air guiding grooves penetrate through the left edge of the left piece and the right edge of the right piece.

[0018] By adopting the above technical solution, through the arrangement of the air guiding grooves, after wearing the mask, the airtightness between the mask and the face is relatively good. Through the opening of the air guiding grooves, a more direct channel is provided for the exhaled air, thus ensuring unobstructed breathing while wearing the mask.

[0019] Preferably, breathing rubber strips are respectively connected to the left side edge of the left piece and the right side edge of the right piece, and the breathing rubber strips are respectively arranged on the side of the left piece away from the air guiding groove and the side of the right piece away from the air guiding groove.

[0020] By adopting the above technical solution, when exhaling, the exhaled air blows open the breathing rubber strips through the guiding action of the air guiding grooves, so as to exhale smoothly. And since the space between the mask and the face is in a positive pressure state, external impurities are not easily introduced into the space between the mask and the face along the air guiding grooves; when inhaling, since the space between the mask and the face is in a relatively negative pressure state, the sucked breathing rubber strips fit against the face to seal the air guiding grooves, thus preventing external impurities from entering the space between the mask and the face, achieving a dust-proof effect, and the inhaled air enters the human body only after being filtered by the mask.

[0021] Preferably, the left piece and the right piece include a waterproof layer on the outer layer, a filter layer on the middle layer, and an antibacterial layer on the inner layer.

[0022] By adopting the above technical solution, through the arrangement of the waterproof layer, it can prevent rainwater from entering the mask when it rains. At the same time, since water is an important carrier of impurities or bacteria, it can also reduce the entry of impurities or bacteria; through the arrangement of the filter layer, the external air is filtered to block the impurities in the air; through the arrangement of the antibacterial layer, the inner layer of the mask has an antibacterial effect. On the one hand, the antibacterial layer is in direct contact with the human skin to protect the human skin. On the other hand, it further filters the air entering the mask from the outside, blocking or killing the vast majority of bacteria, improving the safety of wearing the mask.

[0023] The second object of the present invention is to provide a production process for an antibacterial and warm-keeping mask:

[0024] The above-mentioned object of the present invention is achieved by the following technical solutions:

[0025] A production process of an antibacterial and warm-keeping mask, comprising the following steps:

[0026] S1: Procure raw materials, prepare various types of fabrics required for producing antibacterial masks, and store them separately for standby;

[0027] S2: Three-dimensional knitting, use a three-dimensional knitting machine to produce a variety of composite fabrics required for antibacterial masks;

[0028] S3: Cutting, use a fabric cutting machine to cut a variety of composite fabrics into left pieces, right pieces

[0029] and connecting pieces according to size specifications;

[0030] S4: Mask forming, form and connect the left piece, right piece and connecting piece;

[0031] S5: Sterilization and packaging, sterilize the formed masks with ultraviolet lamps and perform vacuum packaging.

[0032] Preferably, S4 specifically includes: ultrasonically hot-pressing and forming the left piece, right piece and connecting piece at one time.

[0033] By adopting the above technical solution, the left piece, right piece and connecting piece are ultrasonically hot-pressed and formed, realizing the connection and forming of the left piece and the connecting piece, and the right piece and the connecting piece at one time. The antibacterial and warm-keeping mask adopts a one-time forming process, greatly improving the processing efficiency. At the same time, compared with ordinary sewing, there is no need for sewing threads, the appearance is good-looking, and the structure is stable. Description of the Drawings

Detailed implementation manners

[0040] The present invention will be further described in detail below with reference to the accompanying drawings.

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0043] In addition, the descriptions involving "first", "second", etc. in the present invention are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions appears to be contradictory or unable to be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0044] In the present invention, unless otherwise clearly defined and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0045] Refer to Figures 1 to 5, an antibacterial and warm-keeping mask disclosed by the present invention, includes a left piece 1, a right piece 2, and a connecting piece 3 for connecting the left piece 1 and the right piece 2. A bending part 31 is arranged on the inner side of the connecting piece 3, and the connecting piece 3 is buckled on the bridge of the nose through the bending part 31 and fits with the bridge of the nose and the nose wings. Hanging straps 4 are sewn on both the left piece and the right piece.

[0046] The connecting piece 3 includes an upper fixing part 37 and a lower breathing part 38. An outer fixing layer 32 and an inner deformation layer 33, an elastic layer 34 is arranged between the fixing layer 32 and the deformation layer 33, and the fixing layer 32 and the elastic layer 34, and the elastic layer 34 and the deformation layer 33 are bonded by glue. The elastic modulus of the fixing layer 32 is greater than that of the deformation layer 33. In this embodiment, the fixing layer 32 is made of stainless steel sheet, the deformation layer 33 is made of aluminum alloy sheet, and the elastic layer 34 is made of natural latex.

[0047] After the elastic layer 34 is extruded by squeezing the deformation layer 33 and the fixing layer 32, the elastic layer 34 undergoes elastic deformation. After recovery, due to the fact that the elastic modulus of the fixing layer 32 is greater than that of the deformation layer 33, under the action of the elastic layer 34, the deformation layer 33 is extruded by the elastic layer 34 and thus moves in a direction away from the fixing layer 32. When a person wears the mask, the hand squeezes the connecting piece 3 to make the connecting piece 3 fit with the bridge of the nose and the nose wings as much as possible. At this time, the elastic layer 34 undergoes elastic deformation. After letting go, the elastic layer 34 recovers, so that the deformation layer 33 has a tendency to move in a direction close to the bridge of the nose and the nose wings, thereby further improving the fitting property of the antibacterial and warm-keeping mask with the human face.

[0048] A support bar 321 is welded horizontally on the side of the fixing layer 32 away from the deformation layer 33. A protective layer 35 is arranged on the outside of the fixing layer 32, and a support groove 351 is opened on the inner side of the protective layer 35. The support bar 321 is embedded in the support groove 351. The protective layer 35 is made of SMMS non-woven fabric and is bonded to the fixing layer 32.

[0049] Through the arrangement of the support bar 321, the structural strength of the fixing layer 32 is enhanced, thereby improving the anti-deformation ability of the fixing layer 32. Therefore, when the elastic layer 34 squeezes the fixing layer 32 and the deformation layer 33, the deformation amount of the deformation layer 33 is much larger than that of the fixing layer 32, improving the fitting effect of the connecting piece 3 with the human face. At the same time, through the cooperation of the support bar 321 and the support groove 351, the protective layer 35 arranged outside the fixing layer 32 is limited, improving the connection tightness between the protective layer 35 and the fixing layer 32.

[0050] The inner side of the deformation layer 33 is pasted with a skin-friendly layer 36, which is made of natural latex. The skin-friendly layer 36 extends to the inner sides of the entire fixing part 37 and the breathing part 38. Fixed films 39 are pasted on both the upper edge and the lower edge of the skin-friendly layer 36 on the side far from the deformation layer 33. A deformation groove 391 is formed on the side of the fixed film 39 far from the deformation layer 33. In this embodiment, the deformation groove 391 is an arc-shaped groove with a depth of 1-1.5 mm.

[0051] Through the arrangement of the skin-friendly layer 36, the comfort of the mask is improved. The fixed film 39 has good skin-fitting performance. Therefore, through the arrangement of the fixed film 39, the inner edge of the mask can better fit the human face. After wearing the mask, a relatively airtight space can be formed between the mask and the human face covered by the mask, and the outside air cannot directly enter the human nasal cavity and oral cavity without passing through the mask. At the same time, when wearing the mask, by squeezing the mask, the deformation groove 391 deforms to a certain extent, and the air in the deformation groove 391 is squeezed out. After releasing, a negative pressure space is formed between the skin and the deformation groove 391, so that the fixed film 39 is adsorbed on the skin, improving the fitting performance of the mask and the skin.

[0052] The left piece 1 and the right piece 2 include a waterproof layer 11 on the outer layer, a filter layer 12 on the middle layer, and an antibacterial layer 13 on the inner layer. Each layer is sewn and connected by a three-dimensional knitting machine. The waterproof layer 11 is made of SMMS non-woven fabric, the filter layer 12 is made of pure cotton gauze, and the antibacterial layer 13 is made of natural latex. The breathing part 38 has the same structure as the left piece 1 and the right piece 2 and is sewn and connected to the fixing part 37.

[0053] Through the arrangement of the waterproof layer 11, it can prevent rainwater from entering the mask when it rains. At the same time, since water is an important carrier of impurities or bacteria, it can also reduce the entry of impurities or bacteria; through the arrangement of the filter layer 12, the outside air is filtered to block the impurities in the air; through the arrangement of the antibacterial layer 13, the inner layer of the mask has an antibacterial effect. On the one hand, the antibacterial layer 13 is in direct contact with the human skin to protect the human skin. On the other hand, it further filters the air entering the mask from the outside, blocking or killing the vast majority of bacteria, improving the safety of wearing the mask.

[0054] Air guiding grooves 14 are formed on the inner sides of the left piece 1 and the right piece 2. The air guiding groove 14 of the left piece 1 penetrates the left edge of the left piece 1, and the air guiding groove 14 of the right piece 2 penetrates the right edge of the right piece 2. The left side edge of the left piece 1 and the right side edge of the right piece 2 are bonded with breathing rubber strips 15, and the breathing rubber strips 15 are respectively arranged on the side of the left piece 1 far from the air guiding groove 14 and the side of the right piece 2 far from the air guiding groove 14.

[0055] During exhalation, the exhaled air blows open the breathing strip 15 through the guiding action of the air guiding groove 14, enabling smooth exhalation. Since the pressure between the mask and the face is positive, external impurities are not easily introduced between the mask and the face along the air guiding groove 14. During inhalation, since the pressure between the mask and the face is relatively negative, the inhaled breathing strip 15 adheres to the face, sealing the air guiding groove 14, thereby preventing external impurities from entering between the mask and the face, achieving a dust-proof effect, and the inhaled air enters the human body only after being filtered by the mask.

[0056] The present invention also discloses a production process for an antibacterial and warm-keeping mask:

[0057] S1: Procure raw materials, prepare various types of fabrics required for producing antibacterial masks, and store them separately for standby.

[0058] S2: Three-dimensional knitting, use a three-dimensional knitting machine to produce various composite fabrics required for antibacterial masks.

[0059] S3: Cutting, use a fabric cutting machine to cut various composite fabrics into a left piece 1, a right piece 2, and a connecting piece 3 according to size specifications.

[0060] S4: Mask forming, form and connect the left piece 1, the right piece 2, and the connecting piece 3.

[0061] S5: Sterilization and packaging, sterilize the formed mask using an ultraviolet lamp and perform vacuum packaging.

[0062] Among them, S4 specifically refers to integrally ultrasonic thermocompression molding of the left piece 1, the right piece 2, and the connecting piece 3.

[0063] Through ultrasonic thermocompression molding of the left piece 1, the right piece 2, and the connecting piece 3, the connection and molding of the left piece 1 and the connecting piece 3, and the right piece 2 and the connecting piece 3 are achieved at one time. The antibacterial and warm-keeping mask adopts a one-time molding process, greatly improving the processing efficiency. At the same time, compared with ordinary sewing, there is no need for sewing threads, the appearance is good-looking, and the structure is stable.

[0064] In the solution of the present invention, the left piece 1 and the right piece 2 are connected through the connecting piece 3. A bending portion 31 is provided on the connecting piece 3, and the bending portion 31 fits the bridge of the nose, thereby achieving relative sealing between the antibacterial and warm-keeping mask and the face after wearing the antibacterial and warm-keeping mask. The left piece 1 and the right piece 2 are separately arranged, and the overall fit of the mask to the face can be achieved by adjusting the shape and angle of the connecting piece 3 itself, thereby avoiding the problem of poor fit between the mask and the face caused by the relatively large thickness of the mask. The dust-proof, antibacterial, and warm-keeping effects of the mask are ensured.
