Description

Technical Field

[0001] The invention relates to the technical field of masks, and in particular to a novel mask with laser disinfection and sterilization functions. Background Art

[0002] Existing medical masks usually consist of a mask body and a tensioning strap, and the mask body is divided into three layers: inner, middle and outer. The inner layer is made of skin-friendly material, such as ordinary sanitary gauze or non-woven fabric; the middle layer is an isolation filter layer, made of ultra-fine polypropylene fiber melt-blown material, which has the function of blocking particles; the outer layer is a special material antibacterial layer, such as non-woven fabric or ultra-thin polypropylene melt-blown material layer, which has a certain antibacterial effect and can block most droplets, dust and other tiny particles, thereby reducing the risk of viruses invading the human body through the respiratory tract.

[0003] Although existing medical masks provide effective protection against droplets, dust and other tiny particles in terms of design and material, there is still a safety hazard of incomplete disinfection. This is because there may be tiny gaps or damage in the masks, and the virus may still enter the human respiratory system through these gaps. At the same time, if the mask material itself is defective or aged, its protective effect will also decrease. If the virus survives the disinfection process or enters the human respiratory system through the tiny gaps in the mask, it may cause infection. In addition, if the mask is contaminated or damaged during wearing, its protective effect will be greatly reduced, further increasing the risk of virus invasion of the human body.

[0004] In summary, the incomplete disinfection of existing medical masks is a major safety hazard. In order to ensure the protective effect of the masks, improving the mask disinfection technology is a technical problem that urgently needs to be solved in this field. Summary of the invention

[0005] Based on this, in response to the above problems, the present invention provides a new mask with laser disinfection and sterilization function, which has higher disinfection and sterilization efficiency and a wider range of applications, and can provide users with more comprehensive and effective respiratory protection effects.

[0006] To achieve the above-mentioned purpose, the present invention provides a new mask with laser disinfection and sterilization function, comprising a body and a first optical fiber buried in the body, wherein a laser emitter is connected to the upstream of the optical path of the first optical fiber, the laser emitter emits laser and couples into the first optical fiber, the first optical fiber comprises a first light leakage section bent in the body, the laser leaks from the first light leakage section and covers the entire breathing area of ​​the body.

[0007] In one specific embodiment, a reinforcement body for covering part of the nose wing is also provided above the main body, a second optical fiber is buried in the reinforcement body, the second optical fiber includes a second light leakage segment bent in the reinforcement body, laser leaks out from the second light leakage segment and covers the entire breathing area of ​​the reinforcement body.

[0008] In one of the specific embodiments, the first light leakage segment and / or the second light leakage segment adopts at least one of the following methods to achieve uniform distribution of laser in the breathing area: the first method: the first light leakage segment and / or the second light leakage segment is a light leakage optical fiber, which can transmit the laser downstream while leaking the laser uniformly along its length direction; the second method: the cladding of the first light leakage segment and / or the second light leakage segment is locally corroded to form a roughened surface, so that the laser can leak to the surroundings through the roughened surface when passing through the fiber core; the third method: the first light leakage segment and / or the second light leakage segment is provided with uniformly distributed light leakage holes.

[0009] In one specific embodiment, the first optical fiber is arranged in a wave shape, a grid shape, or a spiral shape in the body, and the second optical fiber is arranged in a wave shape, a grid shape, or a spiral shape in the reinforcement body, and the first optical fiber is connected to the second optical fiber.

[0010] In one specific embodiment, the curved portion of the first optical fiber and / or the second optical fiber is in a smooth arc shape.

[0011] In one specific embodiment, laser reflection layers are provided on the inner and outer sides of the first optical fiber and / or the second optical fiber, which can be used to reflect the laser back to the optical fiber layer, increase the intensity and coverage of the laser curtain, ensure the disinfection and sterilization effect of the air, and can also be used to inhibit the laser from leaking out of the mask.

[0012] In one of the specific embodiments, laser shielding layers are provided on both the inner and outer sides of the main body and / or the reinforcement body, and are made of a material that can absorb or reflect laser light, so as to prevent the laser from leaking out of the mask.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0028] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0029] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figure 1As shown, this embodiment provides a new mask with laser disinfection and sterilization function, including a body 10 and a first optical fiber 20 buried in the body 10. A laser emitter 30 is connected to the optical path upstream of the first optical fiber 20. The laser emitter 30 emits laser and couples into the first optical fiber. The laser emitter 30 can be installed on the body 10 or on an ear hanging mechanism such as a tensioning belt 101, or can be arranged in other devices outside the mask, such as a user's hat, clothes or backpack. The first optical fiber 20 includes a first light leakage section 201 bent in the body 10. The laser leaks out from the first light leakage section 201 and covers the entire breathing area of ​​the body 10. The first optical fiber 20 is attached to gauze or non-woven fabric by an adhesive to form a first optical fiber layer. After air contacts the body 10, it flows through the first optical fiber layer formed by the first optical fiber 20. The laser leaking from the first light leakage section 201 forms a laser curtain covering the entire air circulation area. Viruses, bacteria and other microorganisms in the air are irradiated by the laser curtain and directly irradiated into the cell nucleus, causing the cell nucleus to denature, thereby destroying the DNA and RNA of the microorganisms, achieving the effect of disinfection and sterilization. The disinfected air then enters the human respiratory system, ensuring the health of the human body. The embodiment provides a new mask with laser disinfection and sterilization function, which combines laser disinfection and sterilization technology with the protective function of the mask. Compared with traditional masks, it has higher disinfection and sterilization efficiency and a wider range of applications, and eliminates the influence of aging of the mask material layer on the disinfection effect. The laser disinfection device can maintain long-term disinfection and sterilization of the air, and can provide users with more comprehensive and effective respiratory protection effects, greatly reducing the health risks caused by respiratory diseases.

[0031] like Figure 2-Figure 4 As shown, in one of the specific embodiments, a reinforcement body 40 is further provided above the main body 10, and the reinforcement body 40 is used to cover part of the nose wing and fit the nose wing line. A second optical fiber 50 is buried in the reinforcement body 40, and the second optical fiber 50 is attached to the gauze or non-woven fabric by an adhesive. The second optical fiber 50 includes a second light leakage segment 501 bent in the reinforcement body 40, and the laser leaks out from the second light leakage segment 501 and covers the entire breathing area of ​​the reinforcement body 50. Ordinary masks usually have gaps on the upper part of the nose wing, and unsterilized air may enter the respiratory system through the gaps. In order to reduce the health risks caused by viruses, bacteria and other microorganisms contained in the air entering the nasal cavity and then entering the respiratory system through the gaps on the upper part of the nose wing, the reinforcement body 40 is tightly blocked above the nose wing to prevent viruses, bacteria and other microorganisms from entering the nasal cavity from the upper part of the nose wing, providing users with a more comprehensive and effective respiratory protection effect and ensuring the health and safety of the human body.

[0032] like Figure 5-Figure 6As shown, in one of the specific embodiments, the first light leakage section 201 and / or the second light leakage section 501 adopts at least one of the following methods to achieve uniform distribution of laser in the breathing area: the first method: the first light leakage section 201 and / or the second light leakage section 501 is a light leakage optical fiber, which can evenly leak laser along its length direction while transmitting laser downstream, and the light leakage optical fiber only includes a core, and the core in the body or the reinforcement body leaks the laser to produce a stronger laser curtain with a wider coverage, thereby ensuring the disinfection and sterilization effect on the air; the second method: the cladding of the first light leakage section 201 and / or the second light leakage section 501 is locally corroded to form a roughened surface, so that the laser can leak to the surroundings through the roughened surface when passing through the core; the third method: the first light leakage section 201 and / or the second light leakage section 501 are provided with evenly distributed light leakage holes, and the distance between two adjacent light leakage holes 100 is not greater than 5 mm.

[0033] like Figure 1 , Figure 3 As shown, the first optical fiber 20 is wavy in the body 10 and arranged back and forth in the longitudinal direction of the body 10. Figure 2 , Figure 4 As shown, the optical fibers 50 may be arranged in a grid shape in the longitudinal and transverse directions of the main body 10, or may be arranged in a spiral shape. Similarly, the second optical fiber 50 may be arranged in a wavy, grid, or spiral shape in the reinforcement body. The first optical fiber 20 is connected to the second optical fiber 50. The curved layout of the first optical fiber 20 and the second optical fiber 50 not only increases the coverage of the laser, but also improves the uniformity and strength of the laser curtain, ensuring that viruses, bacteria and other microorganisms in the air can be effectively irradiated and killed when passing through the laser curtain.

[0034] like Figure 3-Figure 4 As shown, in one specific embodiment, the bending portion of the first optical fiber 20 and / or the second optical fiber 50 is in a smooth arc shape to reduce energy loss of laser when transmitting in the bending portion of the optical fiber.

[0035] like Figure 7-Figure 8 As shown, in one specific embodiment, a laser reflection layer 60 is provided on both inner and outer sides of the first optical fiber 20 and / or the second optical fiber 50. The laser reflection layer 60 is a mesh reflection layer with a first vent 200 made of silver, aluminum, copper, aluminum alloy, nickel-copper alloy, silicon carbide, silicon, polyimide or polytetrafluoroethylene, or a mesh reflection layer containing nanoparticles of silver, aluminum, copper, aluminum alloy, nickel-copper alloy, silicon carbide, silicon, polyimide or polytetrafluoroethylene. On the one hand, it is used to reflect the laser back to the optical fiber layer, increase the intensity and coverage of the laser curtain, and ensure the disinfection and sterilization effect of the air; on the other hand, it inhibits the laser from leaking out of the mask to a certain extent to avoid damage to the human body caused by the laser.

[0036] like Fig. 9As shown, in one specific embodiment, a laser shielding layer 70 is provided on both the inner and outer sides of the main body 10 and / or the reinforcement body 40. The laser shielding layer 70 is a mesh shielding layer with a second ventilation hole 300 made of silver, aluminum, copper, aluminum alloy, nickel-copper alloy, silicon carbide, silicon, polyimide or polytetrafluoroethylene, activated carbon, to prevent the laser from leaking out of the mask and causing damage to the human body. At the same time, a part of the laser energy is converted into heat in the laser shielding layer 70, although the heat is so small that it can be almost ignored.

[0037] In one embodiment, the mesh reflective layer and the mesh shielding layer can be mesh coatings made of the above materials and adhered to gauze or non-woven fabric.

[0038] like Fig.10 As shown, in one of the specific embodiments, after the laser reflecting layer 60 and the laser shielding layer 70 are stacked and arranged in the mask, the positions of the ventilation holes of the laser reflecting layer 60 and the laser shielding layer 70 are staggered, that is, the first ventilation hole 200 and the second ventilation hole 300 are staggered, which can not only ensure the circulation of air, but also prevent the laser from leaking from the ventilation hole and causing damage to the human body. The shapes of the first ventilation hole 200 and the second ventilation hole 300 are not limited, and can be circular, elliptical, triangular, square, trapezoidal, T-shaped, inverted T-shaped, etc.

[0039] In one specific embodiment, the laser emitter 30 is a semiconductor laser emitter, which emits a laser with a power of 70mW to 200mW and a wavelength of 240nm-270nm. Lasers of this wavelength can penetrate the cell membrane of microorganisms and directly act on the cell nucleus, causing the cell nucleus to denature, thereby destroying the DNA and RNA of the microorganisms and achieving the effect of disinfection and sterilization; the optical fiber is a fluoride glass optical fiber, which can maintain a low loss under a laser with a wavelength of 240nm-270nm and effectively transmit laser energy to the breathing area of ​​the mask.

[0040] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and therefore it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any reference numerals in the claims should not be regarded as limiting the claims involved.

The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope.
