[0028] In the field of power maintenance technology, the power industry often works outdoors or even in the wilderness, especially under extreme climatic conditions, such as extreme cold, hot summer or long-term continuous operation. The temperature difference between the external environment and the human body is huge, or the body sweats a lot, heats up or feels cold due to high-intensity labor. These will have a direct impact on the health and work efficiency of the operators, and in extreme cases may even threaten the life safety of the operators. In addition, most clothing fabrics on the market are made of natural fibers (such as cotton or wool) and blended yarns with polyester (PET) fibers. Clothing made of these materials is not only heavy, but also lacks windproof, waterproof and breathable properties. At the same time, the production of these materials and the difficulty of degrading finished clothing also pose a potential threat to the environment.
[0029] Current solutions rely mainly on choosing appropriate clothing based on the current weather conditions. However, this approach raises new problems. Since the weather is difficult to predict accurately and the temperature may fluctuate dramatically within a day, coupled with the variability of the working environment and the significant difference in temperature at different altitudes, workers have to frequently adjust their clothing to adapt to the changing working conditions. In order to reduce the impact on the environment, the clothing manufacturing industry is working hard to use more degradable materials, but it is still difficult to completely avoid the use of materials that may pollute the environment.
[0030] Therefore, how to more conveniently provide operators wearing work clothes with better working conditions becomes a problem to be solved urgently.
[0031] In view of this, the present application provides a wearable device based on phase change material, which is used to solve the technical problems of inconvenience and poor experience in the prior art. In order to achieve one or part or all of the above purposes or other purposes, the present application proposes a wearable device based on phase change material, a wearable device based on phase change material, and the wearable device includes a work constant temperature vest, a work constant temperature helmet and a local constant temperature protective gear. The work constant temperature vest includes a vest body and a first attachment, and the vest body is covered by the first attachment; the work constant temperature helmet includes a helmet body and a second attachment, the helmet body is formed with a semicircular depression, and the second attachment is arranged at the bottom of the depression; the local constant temperature protective gear includes a fixing part and a third attachment, the third attachment has two opposite side edges, the fixing part is arranged at the edge, and is used to fix the two side edges; the material of the first attachment, the second attachment and the third attachment is at least partially phase change material.
[0032] The following will be combined Figures 1 to 4 , the power fault detection system provided in the embodiment of the present application is described in detail through specific examples. Figure 1 Schematic diagram of the structure of a working constant temperature vest for a wearable device based on phase change material provided in an embodiment of the present application Figure 1 ; Figure 2 Schematic diagram of the first attachment structure of a wearable device based on phase change material provided in an embodiment of the present application Figure 2 ; Figure 3 A schematic diagram of the upward structural view of a working thermostatic helmet of a wearable device based on a phase change material provided in an embodiment of the present application; Figure 4 Schematic diagram of the structure of the local constant temperature protective gear for wearable devices based on phase change materials provided in the embodiment of the present application Figure 3 . One embodiment of the present invention proposes a wearable device based on phase change material, and the wearable device (not shown in the figure) includes a working constant temperature vest 10, a working constant temperature helmet 30 and a local constant temperature protective gear 50. The working constant temperature vest 10 includes a vest body 11 and a first attachment 13, and the vest body 11 is covered by the first attachment 13; the working constant temperature helmet 30 includes a helmet body 31 and a second attachment 33, and the helmet body 31 is formed with a semicircular depression, and the second attachment 33 is arranged at the bottom of the depression; the local constant temperature protective gear 50 includes a fixing part 51 and a third attachment 53, and the third attachment 53 has two opposite side edges, and the fixing part 51 is arranged at the edge and is used to fix the two side edges; the material of the first attachment 13, the second attachment 33 and the third attachment 53 is at least partially phase change material.
[0033] It is understandable that the work thermostatic vest 10 is used to protect the torso of the operator, the work thermostatic helmet 30 is used to protect the head of the operator, and the local thermostatic protective gear 50 is used to protect the persimmon of the operator, wherein the number of local thermostatic protective gear 50 can be multiple, and this application does not make specific restrictions on this. Specifically, the helmet body 31 is used to ensure the structural strength of the work thermostatic helmet 30 itself and protect the operator to avoid collisions that may be caused by the head; the vest body 11 is used to ensure the structural strength of the work thermostatic vest 10 itself and protect the operator to avoid possible collisions toward the torso; the second attachment 33 and the first attachment 13 corresponding to the helmet body 31 and the vest body 11 are used to buffer and absorb the impact force while isolating the influence of the temperature in the external environment on the operator as much as possible, and respectively keeping the head and torso of the operator warm. On the other hand, considering the various activities that may exist in the limbs of the operator in the actual working conditions, the possibility of the limbs being impacted is small, so the local thermostatic protective gear 50 is directly set to take into account the functions of shock absorption, protection and heat preservation with the third attachment 53 at the same time.
[0034] It should be noted that the fixing parts 51 arranged on the two opposite sides of the third attachment 53 enable the two opposite sides of the third attachment 53 to be fixedly connected after being wrapped around the torso. In this way, it can be flexibly used according to the different limb sizes of the operators, ensuring a stable fixing effect, thereby improving the flexibility of use of the local constant temperature protective gear 50 and the phase change-based wearable device.
[0035] It should be noted that phase change materials (PCM) are special substances that have the ability to absorb or release a large amount of latent heat through phase transition (for example, from solid to liquid) within a specific temperature range. The phase change process of this material not only involves the storage of energy, but also the ability to release this energy when needed, thus playing an important role in temperature regulation and thermal energy management. The composition of PCM can be organic or inorganic, covering a wide range of chemical substances. Specifically, they can be organic substances such as paraffin, fatty acids, polyethylene glycol, or inorganic substances such as hydrated salts, metals or alloys. The selection of these materials depends on the required phase change temperature range, thermal stability, cost-effectiveness and other specific application requirements. The material of the first attachment 13, the second attachment 33 and the third attachment 53 is at least partially phase change material, and specifically, the phase change material can be integrated into the fabric or fiber so that it can undergo phase change (usually conversion between solid and liquid) according to changes in ambient temperature. When the temperature rises, the phase change material absorbs heat and changes from solid to liquid; when the temperature drops, the phase change material releases heat and changes from liquid back to solid, thereby achieving automatic regulation of the fabric temperature and moderating the microclimate between the human body and clothing over a certain period of time, creating a more suitable temperature environment, thereby achieving the heat preservation effect of the wearable device based on phase change materials on the workers.
[0036] Specifically, the phase change material used in the present application can be prepared by selecting a eutectic phase change material with high energy storage, high thermal conductivity, no phase separation, no supercooling phenomenon and high density. Eutectic phase change materials are usually a crystalline mixture formed by two or more substances with similar melting points during the crystallization process. Its advantage is that the phase change temperature can be accurately controlled by adjusting the ratio of different components. For example, by mixing tetradecane with octadecane, heneicosane, and docosane for crystallization, a phase change temperature adjustment range of about 10°C can be achieved; when caprylic acid and lauric acid are mixed in a volume ratio of 90:10 and 60:40, the phase change temperatures are 3.77°C and 6.20°C, respectively, and the phase change latent heats are 151.5 J / g and 173.2 J / g, respectively. In this way, the wearable device using the phase change material can adjust the temperature of the supercooled or overheated external environment to a level suitable for the human body, thereby achieving the heat preservation effect of the wearable device based on the phase change material on the operator, improving the operator's work efficiency, and adapting to the variability of the working environment.
[0037] As a feasible implementation, the phase change material parts of the first attachment 13, the second attachment 33 and the third attachment 53 are provided in the form of phase change energy storage microcapsules.
[0038] It should be noted that phase change microcapsule fabric is an advanced intelligent temperature regulating material that achieves intelligent temperature regulation by encapsulating phase change material (PCM) in a microcapsule structure and integrating it into textiles. The core of this fabric lies in its microcapsule technology, which contains core materials that can undergo phase change, such as n-octadecane. These microcapsules are wrapped by a layer of wall material, which is usually composed of polymers to protect the core material and ensure its function. When the external ambient temperature changes, the phase change microcapsule fabric can regulate the temperature through the phase change behavior of the core material. Specifically, when the external temperature rises, the core material will change from solid to liquid, absorbing a large amount of heat in the process, thereby effectively reducing the temperature of the skin surface and bringing a cool feeling to the wearer. Conversely, when the external temperature decreases, the core material will change from liquid to solid, releasing the previously absorbed heat, helping to maintain the temperature of the wearer's body surface and keep warm. Compared with other methods of directly applying phase change materials to fabrics, the microencapsulated structure significantly improves the washability of phase change materials. This means that even after multiple washes, phase change microcapsule fabrics can still maintain their temperature regulating function, extending the service life of the product. Although microcapsule finishing may have a certain impact on the breathability of the fabric, through careful design and finishing, the negative impact on breathability can be minimized while maintaining the comfort of the fabric. In addition, the microcapsule structure of the phase change microcapsule fabric also provides other advantages, such as improving the durability and protection of the material, so that it can maintain stable performance under various environmental conditions. In this way, the user experience of the operator using the wearable device based on phase change materials is further improved.
[0039] Specifically, the core material of the phase change microcapsule fabric includes but is not limited to n-octadecane, n-hexadecane, etc., and the wall material includes but is not limited to melamine-formaldehyde-urea (MFU) resin, etc., and the present application does not make specific limitations on this.
[0040] As a feasible implementation method, phase change energy storage microcapsules are obtained by a microcapsule spinning method.
[0041] As a feasible implementation method, phase change energy storage microcapsules are obtained by a microcapsule post-processing method.
[0042] It is understandable that the formation process of the phase change energy storage microcapsule may include but is not limited to a microcapsule spinning method or a microcapsule finishing method. Preferably, different methods may be selected to prepare the phase change energy storage microcapsule according to different design standards.
[0043] Specifically, microcapsule spinning technology is an innovative method that encapsulates phase change materials (PCMs) in microcapsule structures and integrates them into the fiber production process. The core of this technology is to mix microcapsules containing phase change materials with fiber-forming polymer solutions and then convert them into fibers through a spinning process. The entire process can be divided into three main steps: microcapsule preparation, microcapsule mixing with polymer solution, and the final spinning process. First, the preparation of microcapsules is the basis of the entire technology. In this step, the phase change material (core material) is encapsulated in a layer of polymer wall material to form microcapsules. The size of these microcapsules is usually controlled between 1 and 5 microns to ensure that they can be evenly distributed in the fiber while maintaining sufficient mechanical stability. The preparation of microcapsules involves precise chemical and physical processes to ensure that the core material is completely encapsulated and the thickness and strength of the wall material are sufficient to protect the core material. Secondly, the prepared microcapsules need to be evenly mixed with the fiber-forming polymer solution. This step is crucial to ensure the uniform distribution of the microcapsules in the fiber. The fiber-forming polymer solution can be a variety of different polymers, such as polyacrylonitrile, polyethylene, etc., which can form a continuous fiber structure during the spinning process. The mixing of microcapsules and polymer solutions needs to be carried out under specific conditions to ensure uniform mixing and not destroy the structure of the microcapsules. Finally, the mixed solution containing microcapsules is spun into fibers using traditional spinning methods, such as wet spinning or melt spinning. In this process, the fiber will be evenly coated with phase change microcapsules to form a new type of smart fiber. This fiber has the functions of heat storage and temperature regulation because it is wrapped with phase change microcapsules. The phase change energy storage microcapsule fiber obtained by the microcapsule spinning method shows better stability in subsequent processing and use due to the protective effect of the outer fiber material. This stability is crucial to improving the washing resistance of heat storage and temperature regulation fabrics because it ensures that the microcapsules can maintain their structure and function even after multiple washings, thereby extending the service life and performance of the fabric. The phase change energy storage microcapsules obtained by this method have better stability in subsequent processing due to the protective effect of the fiber material, which is beneficial to improving the washing resistance of heat storage and temperature regulation fabrics.
[0044] On the other hand, the microcapsule finishing method is mainly achieved through two methods: coating and padding. This method does not involve integrating microcapsules into the fiber during the spinning process, but instead adds microcapsules to the fabric surface through a finishing process after the textile production is completed. The phase change energy storage microcapsules obtained by this method are simple to operate, can distribute the microcapsules more evenly in the fabric, and have good protection and stability.
[0045] Specifically, the coating method is a technology that directly integrates phase change microcapsule materials into the surface of fabrics. This method involves mixing phase change microcapsule materials into a coating liquid, and then using adhesion to evenly apply the mixture to the surface of the fabric. After a proper drying process, a film containing phase change microcapsules will be formed on the surface of the fabric, thereby giving the fabric a temperature regulating function. The advantage of this method is that it is simple and quick to operate, and a thin film can be formed on the surface of the fabric according to specific needs. This film not only provides a temperature regulating effect, but also can adjust the thickness and performance of the film according to design requirements. However, the coating method may have a certain impact on the feel and breathability of the fabric. Since the phase change microcapsules are physically attached to the surface of the fabric, the washability of this connection method is relatively poor, and the microcapsules may gradually fall off after multiple washings, affecting the temperature regulating performance and service life of the fabric. The padding method is another technology that integrates phase change microcapsule materials into fabrics. This method involves immersing the fabric in a solution containing phase change microcapsules, then squeezing out the excess solution through a roller, followed by post-treatment steps such as drying and soaping to fix the phase change microcapsules on the fabric. The advantage of the padding method is that the microcapsules can be distributed more evenly in the fiber structure of the fabric, and through post-treatment steps such as soaping, the bonding strength between the microcapsules and the fabric fibers can be significantly improved, enhancing its washability and durability. However, the operation process of the padding method is relatively complicated and involves multiple steps, including dipping, rolling, drying and soaping. These steps not only increase the complexity of the production process, but also may have a certain impact on the feel and air permeability of the fabric. In addition, chemical treatment steps such as soaping may cause certain changes to the original properties of the fabric, and this effect needs to be minimized through precise process control. In summary, the coating method and the padding method each have their advantages and limitations. The coating method is favored for its simple operation and rapid imparting of temperature regulating function to the fabric, while the padding method has advantages for its uniform distribution of microcapsules and improved bonding strength. When choosing a suitable processing method, it is necessary to consider the specific application requirements, cost-benefit analysis and the impact on fabric performance.
[0046] As a feasible implementation, the phase change material parts of the first attachment 13, the second attachment 33 and the third attachment 53 are pure bio-based phase change materials.
[0047] It should be noted that pure bio-based phase change materials are a new type of material that is processed and manufactured using renewable biomass resources through biological, chemical and physical methods. These biomass resources include but are not limited to the contents of crops, trees, plants and animals, and their residues. The development and application of such materials not only respond to the urgent global demand for sustainable development and environmental protection, but also show great potential in many fields due to their unique characteristics. The main characteristics of pure bio-based phase change materials are their green properties, environmental friendliness, renewability of raw materials and ultimate biodegradability. These characteristics enable such materials to return naturally to the ecosystem after the end of their life cycle, thereby reducing the burden on the environment. For example, biomass-based composite phase change materials, which cleverly use the natural pore structure of biomass materials as carriers, not only provide stable support for phase change materials, but also help improve the thermal properties of materials. Because these materials are derived from biomass, they are naturally renewable, which means that they can be continuously replenished by planting and harvesting new biomass without depleting limited resources. In addition, these materials can be naturally decomposed after use, converted into harmless substances and returned to nature, which is in stark contrast to those materials that may have long-term impacts on the environment. Some traditional phase change materials may be difficult to degrade or produce harmful byproducts during the production process, posing potential risks to the environment and human health. In this way, the first attachment 13, the second attachment 33 and the third attachment 53, which are provided with pure bio-based phase change materials, have good renewable performance, that is, the environmental friendliness of the wearable device based on phase change materials is further improved.
[0048] As a possible implementation, the pure bio-based phase change material is % bio-based nylon 66 polymer.
[0049] It should be noted that % bio-based nylon 66 polymer is a nylon material prepared by bioengineering methods using renewable biomass resources as raw materials. Specifically, it refers to the two main monomers in nylon 66: adipic acid (AA) and hexamethylenediamine (HMD), both of which are extracted and produced from biomass resources. During the production process, bio-based AA can reduce greenhouse gas emissions by 85% compared with traditional petroleum-based AA. Compared with traditional petroleum-derived HMD, bio-based HMD can reduce greenhouse gas emissions by 50%. In this way, the first attachment 13, the second attachment 33 and the third attachment 53 provided with % bio-based nylon 66 polymer have good renewable performance, that is, the environmental friendliness of the wearable device based on phase change material is further improved.
[0050] As a feasible implementation manner, the phase change material parts of the first attachment 13, the second attachment 33 and the third attachment 53 are phase change materials with a phase change temperature of 28 degrees Celsius to 31 degrees Celsius.
[0051] It is understandable that the phase change temperature of the phase change material refers to the temperature at which the material undergoes a phase change between a solid and a liquid. Specifically, this temperature marks the specific temperature point at which the material changes from a solid state to a liquid state (melting) or from a liquid state to a solid state (solidification). The phase change temperature of the phase change material portion of the first attachment 13, the second attachment 33, and the third attachment 53 is set to 28 degrees Celsius to 31 degrees Celsius. This temperature range is close to the human body's comfortable temperature, which is conducive to regulating the temperature of the human body's microenvironment, thereby improving the wearing comfort of the wearable device based on phase change materials.
[0052] As a possible implementation, please also refer to Figure 1 and Figure 2 , the vest body 11 and the first attachment 13 are fixedly connected; or, the vest body 11 and the first attachment 13 are detachably connected.
[0053] As a feasible implementation method, please refer to Figure 3 The helmet body 31 and the second attachment 33 are fixedly connected; or, the helmet body 31 and the second attachment 33 are detachably connected.
[0054] It is understandable that the fixedly connected vest body 11 and the first attachment 13 or the helmet body 31 and the second attachment 33 have a longer service life; the detachably connected vest body 11 and the first attachment 13 or the helmet body 31 and the second attachment 33 have a higher flexibility of use, and the damaged parts can be replaced separately without replacing the other. Preferably, different methods can be selected for connecting the vest body 11 and the first attachment 13 or the helmet body 31 and the second attachment 33 according to different design standards, and this application does not specifically limit this.
[0055] As a feasible implementation method, combined with reference Figure 4 The fixing member 51 includes a Velcro tape 511 and a hook and thorn buckle 513 , and the Velcro tape 511 and the hook and thorn buckle 513 are correspondingly arranged on two opposite sides of the third attachment 53 .
[0056] It is understandable that the surface of one side of the hook and thorn buckle 513 is equipped with a plurality of hard and hooked bristles, which enables it to cooperate with the corresponding surface of the Velcro 511, which is a surface with a plurality of fine annular fibers. This structure allows the hook and thorn buckle 513 to be firmly connected with the Velcro 511 through a simple snapping action. Similarly, this design can also be reversed, that is, one side surface of the Velcro 511 is equipped with hooked bristles, and the corresponding surface of the hook and thorn buckle 513 is equipped with fine annular fibers. This application does not specifically limit this interchangeable design to adapt to different usage scenarios and user needs. In a wearable device based on phase change material, this combination of the hook and thorn buckle 513 and the Velcro 511 makes the wearable device more convenient to wear and take off. By applying appropriate pressure at both ends, the bristles of the hook and thorn buckle 513 can easily penetrate the annular fibers of the Velcro 511, or vice versa, to achieve a reversible connection process. This design not only simplifies the wearing process of the wearable device, but also improves the flexibility and comfort of the wearable device. In addition, this combination of hook and barb buckle and Velcro is also highly adaptable and can be adjusted according to the user's body shape and wearing habits to ensure the best fit and comfort. During the use of the wearable device, the user can easily adjust the position of the hook and barb buckle 513 and Velcro 511 as needed to adapt to different activities and environmental conditions. In this way, during the use of the wearable device based on phase change material, a reversible connection process can be achieved by applying pressure at both ends to achieve the buckling process, thereby improving the flexibility of use of the wearable device based on phase change material.
[0057] The above disclosure is only the preferred embodiment of the present application, which certainly cannot be used to limit the scope of rights of the present application. Therefore, equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
