Description

Technical Field

[0001] This invention relates to the field of medical masks, and more specifically, to a mask with active antibacterial function and its method of use. Background Technology

[0002] Medical masks are mostly made of one or more layers of nonwoven fabric composites. The main production processes include meltblown, spunbond, hot air or needle punching, etc. They have the effects of resisting liquids, filtering particulate matter and bacteria, and are a kind of medical protective textile. Medical masks consist of a mask body and a tightening strap. The mask body is divided into three layers: inner, middle and outer. The inner layer is a skin-friendly material (ordinary sanitary gauze or nonwoven fabric), the middle layer is an isolation and filtration layer (ultra-fine polypropylene fiber meltblown material layer), and the outer layer is a special antibacterial layer (nonwoven fabric or ultra-thin polypropylene meltblown material layer).

[0003] The middle filter layer filters air containing bacterial particles through diffusion deposition, interception deposition, inertial deposition, and electrostatic attraction deposition before it is inhaled or exhaled. However, in actual use, the following problems exist.

[0004] Current medical masks only allow airborne bacteria particles to accumulate on the middle filter layer through respiration, without eliminating them. It's difficult for users to completely avoid touching the mask during extended wear, especially when removing it. Once touched, the bacteria deposited on the middle filter layer easily transfer to the user's hands and can cause infection through contact with the eyes, nose, and mouth. This is particularly dangerous for active children. Furthermore, in most households, used masks are simply thrown away without proper disposal facilities, allowing bacteria to be carried indoors and spread, posing a significant risk. Even if antibacterial microbial particles are coated onto the middle filter layer during production, these particles easily evaporate during long-term storage, rendering them ineffective for the user and requiring stringent storage conditions. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the present invention aims to provide a mask with active antibacterial function and its method of use. By improving the original mask structure, a high-elasticity mesh film is laid on the filter layer of the mask. A disposable extrusion mechanism is connected to the outside of the high-elasticity mesh film. During use, antibacterial microparticles filled in the disposable extrusion mechanism are manually squeezed out along with extrusion gas into the high-elasticity mesh film. During prolonged wear and breathing, the airflow causes slight deformation of the high-elasticity mesh film, squeezing the antibacterial microparticles into the filter layer. The diffusion effect of the breathing airflow then diffuses the extruded antibacterial microparticles into a small, localized area nearby. During the diffusion process, the antibacterial particles come into contact with and kill the bacteria. Through the extrusion-type active antibacterial effect of this type of mask during use, bacteria deposited on the mask's filter layer are actively killed, effectively improving the contact safety factor of the mask during use. It is especially suitable for active children who are likely to come into contact with the mask. The mask can also be thrown away directly after use, without worrying about bringing outdoor bacteria indoors and spreading the risk of infection indoors. At the same time, the antibacterial particles are stored in the disposable extrusion mechanism when not in use, which also effectively reduces the possibility of the antibacterial particles being directly coated on the filter layer and volatilizing and becoming ineffective during long-term storage of the mask, increasing the storage time of the mask and reducing the difficulty of storage.

[0007] Technical solution

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

[0009] A mask with active antibacterial function includes an inner protective layer, an outer protective layer, and a filter layer. The filter layer is sandwiched between the inner and outer protective layers. A high-elasticity mesh film is bonded to one side of the filter layer located on the inner protective layer. A connecting hose is fixedly connected to the inlet end of the high-elasticity mesh film. The connecting hose passes through the filter layer and the outer protective layer in sequence and extends to the front side of the outer protective layer. A disposable extrusion mechanism is fixedly connected to the inlet end of the connecting hose. The disposable extrusion mechanism includes an extrusion airbag and a disposable extrusion head. The connecting hose is fixedly connected to the outlet end of the disposable extrusion head. The extrusion airbag is fixedly connected to the inlet end of the disposable extrusion head. The extrusion airbag is filled with a large number of antibacterial microparticles and extrusion gas that is filled in along with the antibacterial microparticles. The extrusion gas diffuses into the disposable extrusion head.

[0010] Furthermore, a fixing member is snapped into the inner wall of the disposable extrusion head near the connecting hose. A tension spring is fixedly connected to the end of the fixing member away from the extrusion airbag, and a pressure ball is fixedly connected to the end of the tension spring away from the fixing member. The pressure ball abuts against the outlet end of the disposable extrusion head. A disposable sealing film is fixedly connected to the inner wall of the disposable extrusion head near the connecting hose. When the user squeezes the extrusion airbag, the combined pressure of the antibacterial microparticles and the extrusion gas will stretch the tension spring, causing the pressure ball to push towards the disposable sealing film. The pressure ball will rupture the disposable sealing film, allowing the antibacterial microparticles to smoothly fill the entire high-elasticity mesh film under the guidance of the extrusion gas. At the same time, the rupture of the disposable sealing film also means that the disposable extrusion mechanism loses its sealing effect, effectively reducing the possibility of the mask being recycled by criminals and reused with refilled antibacterial microparticles, thus improving the safety of product use.

[0011] Furthermore, the pressure ball is fixedly connected to the end wall of the disposable sealing film with a needle. When the product is used more by children in the current production batch, the pressure ball's pushing and squeezing of the disposable sealing film is improved to the needle's puncturing of the disposable sealing film. This makes the process of the disposable sealing film breaking through the squeezing of the airbag smoother, and children do not need to squeeze the airbag with great force, thus improving the children's user experience.

[0012] Furthermore, the antibacterial microparticles are made by thoroughly mixing microbial communities and water-soluble powders, granulating them using a granulation device, and polishing the surface of the antibacterial microparticles after granulation. The smooth surface of the antibacterial microparticles makes it easier for them to fill the entire high-elasticity mesh film under the extrusion gas. At the same time, they are also easier to be pressed into the filter layer under the micro-deformation of the high-elasticity mesh film, and diffuse within a small area under the influence of the user's breathing airflow. The diffused antibacterial microparticles dissolve upon contact with the water vapor carried by the user's breathing airflow, causing the microbial community to undergo secondary penetration and diffusion within a small area, further increasing the contact probability between the antibacterial microparticles and bacterial microparticles, improving the sterilization effect. In addition, the absorption of water vapor by the antibacterial microparticles also further improves the water absorption effect of the mask and improves the wearing comfort.

[0013] Furthermore, the fiber elasticity of the inner protective layer is greater than that of the outer protective layer, resulting in inconsistent bending degrees between the inner and outer protective layers under the influence of the user's breathing airflow. The inner protective layer has a greater degree of bending, while the outer protective layer has a lower degree of bending. This allows the micro-deformation process of the highly elastic mesh film to proceed smoothly, enabling the antibacterial microparticles to be easily squeezed into the filter layer, thus increasing the practicality of the product.

[0014] Furthermore, the high-elasticity mesh film has a U-shaped structure, and its open end is bonded to the filter layer. The high-elasticity mesh film contains multiple shaping filaments, all of which are bonded to the filter layer. Compared to traditional masks, the high-elasticity mesh film may reduce the fit between the mask body and the user's face. The shaping filaments offset the elastic recovery effect of the high-elasticity mesh film on the mask body. At the same time, the shaping effect of the shaping filaments makes the mask more suitable for people with different face shapes, further increasing the practicality of the product.

[0015] Furthermore, the amount of extrusion gas injected into the antibacterial microparticles is greater than the volume of the high-elasticity wire mesh film. By over-injecting the extrusion gas, the air pressure is increased, thereby increasing the gas extrusion speed, so that the antibacterial microparticles can smoothly and completely fill the entire high-elasticity wire mesh film under the action of the gas.

[0016] Furthermore, the disposable extrusion mechanism is located on the lower side of the outer protective layer to avoid the possibility of the disposable extrusion mechanism obstructing the glasses when people wearing glasses use the product, thus improving the user's wearing experience.

[0017] Furthermore, the inner protective layer, outer protective layer, and filter layer are pressed together using a hot-pressing process to improve the structural strength of the product.

[0018] Furthermore, a method for using a mask with active antibacterial function includes the following steps:

[0019] S1. Manual squeezing: After putting on the mask, the user manually squeezes the airbag forcefully.

[0020] S2. Guided filling: Under the combined pressure of a large number of antibacterial microparticles and extrusion gas filling the extrusion air bladder, the one-time extrusion head breaks, and the antibacterial microparticles are rapidly ejected along with the extrusion gas. Under the guidance of the extrusion gas, the high-elasticity wire mesh membrane is instantly filled with a large number of antibacterial microparticles, while the extrusion gas is released from the high-elasticity wire mesh membrane and the filter layer.

[0021] S3. Compression Deposition: Under the influence of the user's breathing airflow, the overall deformation of the mask will cause the high-elasticity mesh film to undergo micro-deformation, and the antibacterial particles filled in the high-elasticity mesh film will be squeezed into the filter layer.

[0022] S4. Breathing diffusion: The antibacterial microparticles squeezed into the filter layer diffuse to both sides in a small range under the influence of the user's breathing airflow;

[0023] S5. Contact sterilization: The diffused antibacterial particles come into contact with bacterial particles deposited on the filter layer due to prolonged breathing by the user, killing the bacteria.

[0024] Beneficial effects

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

[0026] (1) This solution improves the original mask structure by laying a high-elasticity mesh film on the filter layer of the mask. The high-elasticity mesh film is connected to a disposable extrusion mechanism. During use, the antibacterial microparticles filled in the disposable extrusion mechanism are squeezed out along with the extrusion gas into the high-elasticity mesh film by manual squeezing. When the user wears the mask for a long time and breathes, the breathing airflow causes the high-elasticity mesh film to undergo slight deformation, squeezing the antibacterial microparticles into the filter layer. The diffusion effect of the breathing airflow diffuses the antibacterial microparticles squeezed into the filter layer to a small local area nearby. During the diffusion process, the antibacterial microparticles come into contact with bacterial microparticles and are then absorbed into the filter layer. The mask kills bacteria through an extrusion-based active antibacterial effect, effectively eliminating bacteria deposited on the filter layer and improving the safety of contact during use. It is especially suitable for active children who are more likely to come into contact with the mask. The mask can also be discarded after use, eliminating concerns about bringing outdoor bacteria indoors and spreading infection risks. Furthermore, the antibacterial microparticles are stored in the disposable extrusion mechanism when not in use, which effectively reduces the possibility of the antibacterial microparticles being directly coated on the filter layer and volatilizing and becoming ineffective during long-term storage. This increases the storage time of the mask and reduces the difficulty of storage.

[0027] (2) When the user squeezes the airbag, the combined pressure of the antibacterial microparticles and the extrusion gas will stretch the tension spring, which will push the pressure ball towards the disposable sealing film. The pressure ball will break the disposable sealing film, so that the antibacterial microparticles can be smoothly filled into the entire high elastic mesh film under the guidance of the extrusion gas. At the same time, the breaking of the disposable sealing film also means that the disposable extrusion mechanism loses its sealing effect, which effectively reduces the possibility of the mask being recycled by criminals and refilled with antibacterial microparticles for reuse, thus improving the safety of product use.

[0028] (3) The pressure ball is fixedly connected to the end wall of the disposable sealing film with a needle. When the product is used more by children in the current production batch, the pressure ball pushes and squeezes the disposable sealing film to puncture the disposable sealing film with the needle. This makes the process of the disposable sealing film breaking through the squeezing of the air bag smoother. Children do not need to squeeze the air bag with great force, thus improving the children's user experience.

[0029] (4) The antibacterial microparticles are made by fully mixing microbial groups and water-soluble powders and granulating them using granulation equipment. After granulation, the surface of the antibacterial microparticles is polished. The smooth surface of the antibacterial microparticles makes it easier to fill the entire high-elasticity mesh film under the extrusion gas. At the same time, it is also easier to be pressed into the filter layer under the micro-deformation of the high-elasticity mesh film. Under the influence of the user's breathing airflow, the antibacterial microparticles diffuse in a small area. The diffused antibacterial microparticles dissolve upon contact with the water vapor carried by the user's breathing airflow, causing the microbial groups to undergo secondary penetration and diffusion in a small area. This further increases the contact probability between the antibacterial microparticles and bacterial microparticles, improving the sterilization effect. In addition, the absorption of water vapor by the antibacterial microparticles further improves the water absorption effect of the mask and improves the wearing comfort.

[0030] (5) The fiber elasticity of the inner protective layer is greater than that of the outer protective layer, so that the bending degree of the inner and outer protective layers is inconsistent under the influence of the user's breathing airflow. The bending degree of the inner protective layer is greater and the bending degree of the outer protective layer is less. In this way, the micro-deformation process of the high elasticity mesh film can proceed smoothly, which also allows the antibacterial particles to be squeezed into the filter layer smoothly, increasing the practicality of the product.

[0031] (6) The high-elasticity mesh film has a U-shaped structure and its open end is bonded to the filter layer. The high-elasticity mesh film has multiple shaping filaments inside, and all the shaping filaments are bonded to the filter layer. Compared with traditional masks, the elasticity of the high-elasticity mesh film may reduce the fit between the mask body and the user's face. The shaping filaments are used to offset the elastic recovery effect of the high-elasticity mesh film on the mask body. At the same time, the shaping effect of the shaping filaments makes the mask more suitable for people with different face shapes, further increasing the practicality of the product.

[0032] (7) The amount of extrusion gas injected into the antibacterial microparticles is greater than the volume of the high elasticity wire mesh film. By over-injecting the extrusion gas, the air pressure is increased, thereby increasing the gas extrusion speed, so that the antibacterial microparticles can smoothly and completely fill the entire high elasticity wire mesh film under the action of the gas.

[0033] (8) The disposable extrusion mechanism is located on the lower side of the outer protective layer to avoid the possibility of the disposable extrusion mechanism blocking the glasses when people wearing glasses use the product, thus improving the user's wearing experience.

[0034] (9) The inner protective layer, outer protective layer and filter layer are pressed together by hot pressing process to improve the structural strength of the product. Attached Figure Description

[0051] Please see Figure 1-10 A mask with active antibacterial function and its method of use are disclosed. The mask includes an inner protective layer, an outer protective layer, and a filter layer. The filter layer is sandwiched between the inner and outer protective layers. A high-elasticity mesh film 1 is bonded to one side of the filter layer located on the inner protective layer. A connecting hose 3 is fixedly connected to the inlet end of the high-elasticity mesh film 1. The connecting hose 3 passes through the filter layer and the outer protective layer in sequence and extends to the front side of the outer protective layer. A disposable extrusion mechanism 2 is fixedly connected to the inlet end of the connecting hose 3. The disposable extrusion mechanism 2 includes an extrusion airbag 201 and a disposable extrusion head 202. The connecting hose 3 is fixedly connected to the outlet end of the disposable extrusion head 202. The extrusion airbag 201 is fixedly connected to the inlet end of the disposable extrusion head 202. The extrusion airbag 201 is filled with a large number of antibacterial microparticles 4 and extrusion gas that is filled in along with the antibacterial microparticles 4. The extrusion gas diffuses into the disposable extrusion head 202.

[0052] A method for using a mask with active antibacterial function includes the following steps:

[0053] S1. Manual squeezing: After putting on the mask, the user manually squeezes the airbag 201 forcefully.

[0054] S2. Guided filling: Under the combined pressure of a large number of antibacterial microparticles 4 filled in the extrusion air bladder 201 and the extrusion gas, the one-time extrusion head 202 ruptures, and the antibacterial microparticles 4 are rapidly ejected along with the extrusion gas. Under the guidance of the extrusion gas, the high-elasticity wire mesh membrane 1 is instantly filled with a large number of antibacterial microparticles 4, while the extrusion gas is released from the high-elasticity wire mesh membrane 1 and the filter layer.

[0055] S3. Squeezing and Deposition: Under the influence of the user's breathing airflow, the overall deformation of the mask will cause the high-elasticity mesh film 1 to undergo slight deformation, and the antibacterial particles 4 filled in the high-elasticity mesh film 1 will be squeezed into the filter layer.

[0056] S4. Breathing diffusion: The antibacterial particles 4, squeezed into the filter layer, diffuse to both sides in a small range under the influence of the user's breathing airflow.

[0057] S5. Contact sterilization: The diffused antibacterial particles 4 come into contact with bacterial particles deposited on the filter layer due to prolonged breathing by the user, killing the bacteria.

[0058] This invention improves upon the existing mask structure by laying a high-elasticity mesh membrane 1 on the mask's filter layer. The high-elasticity mesh membrane 1 is externally connected to a disposable extrusion mechanism 2. During use, antibacterial microparticles 4, filled within the disposable extrusion mechanism 2, are manually extruded along with extrusion gas into the high-elasticity mesh membrane 1. During prolonged wear and breathing, the airflow causes slight deformation of the high-elasticity mesh membrane 1, extruding the antibacterial microparticles 4 into the filter layer. The diffusion effect of the breathing airflow further disperses the extruded antibacterial microparticles 4 into a small, localized area, where they come into contact with bacterial particles. This type of mask kills bacteria through its extrusion-based active antibacterial effect, effectively increasing the safety factor of the mask during use. It is especially suitable for active children who are more likely to come into contact with the mask. The mask can also be thrown away directly after use, so there is no need to worry about bringing outdoor bacteria indoors and spreading the risk of infection. At the same time, the antibacterial particles 4 are stored in the disposable extrusion mechanism 2 when not in use, which also effectively reduces the possibility of the antibacterial particles 4 being directly coated on the filter layer and volatilizing and becoming ineffective during long-term storage of the mask. This increases the storage time of the mask and reduces the difficulty of storage.

[0059] Please see Figure 5A fixing member 2021 is snapped into the inner wall of the disposable extruder 202 near the connecting hose 3. A tension spring 2022 is fixedly connected to the end of the fixing member 2021 away from the extrusion air bladder 201. A pressure ball 2023 is fixedly connected to the end of the tension spring 2022 away from the fixing member 2021. The pressure ball 2023 abuts against the outlet end of the disposable extruder 202. A disposable sealing film 2024 is fixedly connected to the inner wall of the disposable extruder 202 near the connecting hose 3. When the user squeezes the extrusion air bladder 201, the antibacterial particles 4 and the extruded material are released. The combined pressure of the gas stretches the tension spring 2022, which in turn pushes the pressure ball 2023 toward the disposable sealing film 2024. The pressure ball 2023 ruptures the disposable sealing film 2024, allowing the antibacterial microparticles 4 to be successfully filled into the entire high-elasticity mesh film 1 under the guidance of the extrusion gas. At the same time, the rupture of the disposable sealing film 2 also means that the disposable extrusion mechanism 2 loses its sealing effect, effectively reducing the possibility of the mask being recycled by criminals and reused by refilling the antibacterial microparticles 4, thus improving the safety of product use.

[0060] The pressure ball 2023 is fixedly connected to the end wall of the disposable sealing film 2024 with a needle 5. When the product is used more by children in the current production batch, the pushing and squeezing of the disposable sealing film 2024 by the pressure ball 2023 is improved to the puncturing of the disposable sealing film 2024 by the needle 5. This makes the process of the disposable sealing film 2024 breaking through the squeezing of the air bag 201 smoother. Children do not need to squeeze the air bag 201 with great force, thus improving the user experience for children.

[0061] Please see Figure 7 , Figure 9 and Figure 10 The antibacterial microparticles 4 are made by thoroughly mixing microbial communities and water-soluble powders and granulating them using granulation equipment. After granulation, the surface of the antibacterial microparticles 4 is polished. The smooth surface of the antibacterial microparticles 4 makes it easier to fill the entire high-elasticity mesh membrane 1 under the action of extrusion gas. At the same time, it is also easier to be pressed into the filter layer under the slight deformation of the high-elasticity mesh membrane 1. Under the action of the user's breathing airflow, they diffuse in a small area. The diffused antibacterial microparticles 4 dissolve upon contact with the water vapor carried by the user's breathing airflow, causing the microbial community to undergo secondary penetration and diffusion in a small area. This further increases the contact probability between the antibacterial microparticles 4 and bacterial particles, improving the sterilization effect. In addition, the absorption of water vapor by the antibacterial microparticles 4 further improves the water absorption effect of the mask and improves the wearing comfort.

[0062] Please see Figure 8The fiber elasticity of the inner protective layer is greater than that of the outer protective layer, which causes the inner and outer protective layers to bend at different degrees under the influence of the user's breathing airflow. The inner protective layer bends more and the outer protective layer bends less. This allows the micro-deformation process of the high-elasticity mesh film 1 to proceed smoothly, which in turn allows the antibacterial particles 4 to be squeezed into the filter layer, increasing the practicality of the product.

[0063] Please see Figure 7 and Figure 9 The high-elasticity mesh film 1 has a U-shaped structure, and its open end is bonded to the filter layer. The high-elasticity mesh film 1 contains multiple shaping filaments 101, and all the shaping filaments 101 are bonded to the filter layer. Compared with traditional masks, the elasticity of the high-elasticity mesh film 1 may reduce the fit between the mask body and the user's face. The shaping filaments 101 offset the elastic recovery effect of the high-elasticity mesh film 1 on the mask body. At the same time, the shaping effect of the shaping filaments 101 makes the mask more suitable for people with different face shapes, further increasing the practicality of the product.

[0064] Please see Figure 6 The amount of extrusion gas injected into the antibacterial microparticles 4 is greater than the volume of the high-elasticity wire mesh film 1. By over-injecting the extrusion gas, the air pressure is increased, thereby increasing the gas extrusion speed, so that the antibacterial microparticles 4 can smoothly and completely fill the entire high-elasticity wire mesh film 1 under the action of the gas.

[0065] Please see Figure 1 The inner protective layer, outer protective layer, and filter layer are pressed together using a hot-pressing process to improve the structural strength of the product.

[0066] Please see Figure 2 The disposable extrusion mechanism 2 is located on the lower side of the outer protective layer to avoid the possibility of the disposable extrusion mechanism 2 obstructing the glasses when people wearing glasses use the product, thus improving the user's wearing experience.

[0067] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
