Description

Technical Field

[0001] This invention relates to wearable cooling devices, specifically to an integrated, water-repellent, sweat-wicking, multi-layered cooling vest. Background Technology

[0002] Currently, the mainstream cooling clothing on the market mainly falls into the following three categories: Air-cooled clothing has limitations such as being severely affected by the environment, not fitting snugly and affecting movement, and relying on a power source.

[0003] Ice pack vests rely on melting ice to absorb heat, but they suffer from problems such as short cooling time, poor user experience, need for frequent replacement or freezing for regeneration, and lack of flexibility.

[0004] Regular PCM cooling clothing: Compared to air-cooled clothing and ice pack vests, it has improvements in all aspects, but still has problems such as condensation affecting comfort and excessive absorption of external heat leading to a shorter cooling time.

[0005] The above three types of products struggle to balance portability, battery life, and user experience, limiting their application in a wider range of scenarios. The market urgently needs an all-in-one cooling vest that strikes a good balance between efficient cooling and long battery life, while also being water-repellent, heat-insulating, sweat-wicking, and easy to wear, to meet the individual thermal management needs of outdoor work, sports protection, and special environments. Summary of the Invention

[0006] The technical problem to be solved by this invention is to provide an integrated water-repellent and sweat-wicking multi-layer cooling vest. The three-layer structure can not only effectively delay the time of external heat conduction into the body, but also reduce the direct contact between external heat and the middle PCM cooling and cold storage layer, thereby improving cooling efficiency and durability, thus effectively achieving a good balance between efficient cooling and long battery life.

[0007] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: an integrated water-repellent and sweat-wicking multi-layer cooling vest, including a front piece and a back piece, with shoulder straps connected to each other on both sides of the upper end of the front piece and the back piece, and waist belts connected to each other on both sides of the lower end of the front piece and the back piece, each of the front piece and the back piece including an outer layer, a middle layer and an inner layer, the outer layer being a reflective heat insulation layer, the middle layer being a PCM cooling and cold storage layer, and the inner layer being a sweat-wicking and moisture-wicking layer.

[0008] The beneficial effects of this invention are as follows: both the front and rear layers are designed with a multi-layer structure to achieve a synergistic effect of heat insulation, cooling and sweat absorption and moisture wicking. The outer layer blocks external heat radiation, the middle layer continuously absorbs body heat to achieve long-lasting cooling, and the inner layer quickly wicks away sweat and moisture to ensure that the body surface is dry and comfortable. The three-layer structure can not only effectively delay the time of external heat conduction inward, but also reduce the direct contact between external heat and the middle PCM cooling and cold storage layer, thereby improving cooling efficiency and durability, thus achieving a good balance between efficient cooling and long-lasting battery life.

[0009] Furthermore, the bottom and sides of the outer layer are fixedly connected to the bottom and sides of the inner layer to form a pocket-shaped structure with an open top, and the middle layer is laid flat inside the pocket-shaped structure.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the outer and inner layers form a pocket shape with an open top, which can effectively accommodate the middle PCM cooling and cold storage layer, ensuring that the PCM cold storage layer does not shift during use. At the same time, it facilitates the quick disassembly and replacement of the PCM cooling and cold storage layer, allowing the PCM cooling and cold storage layer with the corresponding phase change temperature to be flexibly replaced according to different ambient temperatures or individual needs, effectively improving the flexibility and adaptability of the vest.

[0011] Furthermore, the outer layer is police mesh fabric with reflective strips on its outer side.

[0012] The beneficial effects of adopting the above-mentioned further solutions are as follows: Police mesh fabric is generally made of nylon or polyester with high gloss. It can not only effectively block solar radiation and reflect most of the heat, reducing the heat absorption of the outer layer, but also has a certain water-repellent property, which can effectively prevent raindrops from penetrating. In addition, its mesh structure also ensures good breathability. The reflective strips further reflect sunlight and effectively enhance nighttime visibility, thus effectively improving the safety performance of wearing the garment.

[0013] Furthermore, the middle layer includes a waterproof soft film and multiple PCM cooling and cold storage units disposed on the waterproof soft film.

[0014] The beneficial effects of adopting the above-mentioned further solution are: the waterproof soft film can effectively prevent the condensate generated by the PCM cooling and cold storage unit during the phase change process from seeping out, thereby improving its dry and wet separation effect. At the same time, the waterproof soft film can also isolate the PCM cooling and cold storage unit, preventing it from coming into contact with sweat or air, which would cause it to deteriorate and affect the cooling effect. In addition, multiple PCM cooling and cold storage units can precisely control the temperature of multiple areas on the body surface, avoiding local overcooling or waste of cold energy, and effectively improving the comfort and cooling efficiency.

[0015] Furthermore, the waterproof soft film is stacked with two layers of the same shape, and the inner waterproof soft film is provided with a receiving groove. The PCM cooling and cold storage unit includes PCM cold storage agent, which is filled in the receiving groove. The two layers of waterproof soft film are heat-pressed together to seal the receiving groove.

[0016] The beneficial effects of adopting the above-mentioned further solution are: after the two layers of waterproof soft rubber sheets are hot-pressed together, the receiving groove is sealed, so that the filled PCM cooling and cold storage unit is completely sealed, effectively preventing displacement or leakage during use, and further improving safety and stability. The PCM cold storage agent in the PCM cooling and cold storage unit is generally composed of inorganic hydrated salts (such as CaCl2·6H2O, NaNO3·10H2O, Na2SO4·10H2O, etc.) or organic phase change materials (such as paraffin wax, fatty acids), which utilize the absorption or release of a large amount of latent heat during the phase change process to achieve the temperature control effect. Therefore, by adjusting the ratio of each component of the PCM cold storage agent in the cold storage and cooling bag, different phase change temperatures (such as 28℃, 25℃, 22℃, etc.) can be controlled. Therefore, by selecting PCM cold storage agents with different component ratios as PCM cooling and cold storage units, the set temperature of the cold storage and cooling vest can be changed to meet different needs.

[0017] Furthermore, the receiving slots include multiple slots, and gaps are provided between each receiving slot.

[0018] The beneficial effects of adopting the above-mentioned further solution are: multiple receiving slots independently accommodate each PCM cooling and cold storage unit, which can effectively avoid mutual friction and wear between adjacent PCM cooling and cold storage units, extend service life, and the gap between each receiving slot not only helps air circulation, improves heat dissipation efficiency of the body surface, and enhances cooling comfort, but also effectively avoids excessive concentration of cold sensation, reduces discomfort caused by local low temperature, and each receiving slot also has a massage function, further improving the wearer's experience.

[0019] Furthermore, the waterproof soft film is also provided with multiple through holes, each of which is located in the gap between adjacent receiving grooves.

[0020] The beneficial effects of adopting the above-mentioned further solutions are: the through-hole design not only improves the breathability of the waterproof soft film, but also effectively reduces the risk of condensation inside the material due to temperature differences, further enhancing wearing comfort.

[0021] Furthermore, the inner layer is composed of a sweat-absorbing and breathable fleece surface and a waterproof and moisture-wicking smooth surface, with the sweat-absorbing and breathable fleece surface located on the outside of the pocket-shaped structure and the waterproof and moisture-wicking smooth surface located on the inside of the pocket-shaped structure.

[0022] The beneficial effects of adopting the above-mentioned further solution are: the sweat-absorbing and breathable fleece can quickly absorb moisture from the skin, and its soft and skin-friendly texture greatly improves the comfort of use. The waterproof and moisture-wicking smooth surface is used to prevent the condensation water generated by the PCM cooling and cold storage unit during the cooling process from seeping back into the human skin through the sweat-absorbing and breathable fleece and affecting the comfort of wearing, thereby further realizing the effect of dry and wet separation.

[0023] Furthermore, the shoulder straps and waist belts of the front piece are integrally formed with their outer layers, and the shoulder straps and waist belts of the rear piece are integrally formed with their outer layers. The shoulder straps of the front piece and the waist belts of the rear piece are all connected by detachable connectors.

[0024] The beneficial effects of adopting the above-mentioned further solutions are: the one-piece molding design of the shoulder strap and waist belt improves the overall structure and durability, while the detachable connectors enable convenient assembly and separation of the front and back pieces, making it easy to wear, clean and replace, and effectively extending the overall service life of the product.

[0025] Furthermore, the detachable connector is one of Velcro, straps, cords, or buckles.

[0026] The beneficial effects of adopting the above-mentioned further solutions are: Velcro, straps, ties, and buckles are not only simple in structure and easy to operate, greatly improving the convenience of putting on and taking off vests, but also have low manufacturing costs, which is conducive to large-scale promotion and application. At the same time, the tightness can be flexibly adjusted according to the body shape of different users, effectively improving the fit and comfort of wearing. Attached Figure Description

[0030] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0031] Example 1 like Figures 1-4 As shown, this embodiment provides an integrated water-repellent, sweat-wicking, multi-layer cooling vest, including a front piece 1 and a back piece 2. The upper sides of the front piece 1 and the back piece 2 are provided with interconnected shoulder straps 3, and the lower sides of the front piece 1 and the back piece 2 are provided with interconnected waist belts 4. The front piece 1 and the back piece 2 each include an outer layer 5, a middle layer 6, and an inner layer 7. The outer layer 5 is a reflective heat insulation layer, the middle layer 6 is a PCM cooling and cold storage layer, and the inner layer 7 is a sweat-wicking and moisture-wicking layer.

[0032] In this embodiment, both the front layer 1 and the rear layer 2 are designed with a multi-layer structure to achieve the synergistic effect of heat insulation, cooling and sweat absorption and moisture wicking. The outer layer 5 blocks external heat radiation, the middle layer 6 continuously absorbs body heat to achieve long-term cooling, and the inner layer 7 quickly wicks away sweat and moisture to ensure that the body surface is dry and comfortable. The three-layer structure can not only effectively delay the time of external heat conduction inward, but also reduce the direct contact between external heat and the PCM cooling and cold storage layer of the middle layer 6, thus improving the cooling efficiency and durability, thereby achieving a good balance between efficient cooling and long-lasting battery life.

[0033] Example 2 like Figure 1 and 3 As shown, based on Embodiment 1, in this embodiment, the bottom and sides of the outer layer 5 are fixedly connected to the bottom and sides of the inner layer 7 to form a pocket-shaped structure with an open top, and the middle layer 6 is laid flat inside the pocket-shaped structure.

[0034] In this embodiment, the outer layer 5 and the inner layer 7 form a pocket shape with an open top, which can effectively accommodate the PCM cooling and cold storage layer of the middle layer 6, ensuring that the PCM cooling and cold storage layer does not shift during use. At the same time, it facilitates the quick disassembly and replacement of the PCM cooling and cold storage layer, allowing the PCM cooling and cold storage layer with the corresponding phase change temperature to be flexibly replaced according to different ambient temperatures or individual needs, effectively improving the flexibility and adaptability of the vest.

[0035] Example 3 like Figure 2 and 4 As shown, based on Embodiment 2, the outer layer 5 in this embodiment is a police mesh fabric with reflective strips 8 on its outer side.

[0036] In this embodiment, the police mesh fabric is generally made of nylon or polyester with high gloss. It can not only effectively block solar radiation and reflect most of the heat, reducing the heat absorption of the outer layer 5, but also has a certain water-repellent property, which can effectively prevent raindrops from penetrating. Its mesh structure also ensures good breathability. The reflective strip 8 further reflects sunlight and effectively enhances nighttime visibility, thus effectively improving the safety performance of wearing the garment.

[0037] Example 4 like Figure 5 and 6 As shown, based on Embodiment 2, the middle layer 6 in this embodiment includes a waterproof soft film 61 and a plurality of PCM cooling and cold storage units 62 disposed on the waterproof soft film 61.

[0038] In this embodiment, the waterproof soft rubber sheet 61 can effectively prevent the condensate generated by the PCM cooling and cold storage unit 62 during the phase change process from seeping out, thereby improving its dry and wet separation effect. At the same time, the waterproof soft rubber sheet 61 can also isolate the PCM cooling and cold storage unit 62 to prevent it from coming into contact with sweat or air, which would cause it to deteriorate and affect the cooling effect. In addition, multiple PCM cooling and cold storage units 62 can precisely control the temperature of multiple areas on the body surface, avoiding local overcooling or waste of cold energy, and effectively improving the comfort and cooling efficiency.

[0039] Example 5 like Figure 6 As shown, based on Example 4, the waterproof soft film 61 in this example has two layers of the same shape stacked together. The inner waterproof soft film 61 is provided with a receiving groove 63. The PCM cooling and cold storage unit 62 includes PCM cold storage agent. The PCM cold storage agent is filled in the receiving groove 63. The two layers of waterproof soft film 61 are hot-pressed together to seal the receiving groove 63.

[0040] In this embodiment, the receiving groove 63 is sealed after the two layers of waterproof soft rubber sheets 61 are hot-pressed together, so that the filled PCM cooling and cold storage unit 62 is completely sealed, effectively preventing displacement or leakage during use, and further improving safety and stability. The PCM cold storage agent in the PCM cooling and cold storage unit 62 is generally composed of inorganic hydrated salts such as CaCl2·6H2O, NaNO3·10H2O, Na2SO4·10H2O, etc., or organic phase change materials such as paraffin and fatty acids. It utilizes the absorption or release of a large amount of latent heat during its phase change to achieve the temperature control effect. Therefore, by adjusting the ratio of each component of the PCM cold storage agent in the cold storage and cooling bag, different phase change temperatures such as 28℃, 25℃, 22℃, etc. can be controlled. Therefore, by selecting PCM cold storage agents with different component ratios as the PCM cooling and cold storage unit 62, the set temperature of the cold storage and cooling vest can be changed to meet different needs.

[0041] Example 6 like Figure 5 and 6 As shown, based on Embodiment 5, the receiving groove 63 in this embodiment includes multiple grooves, and gaps are provided between each receiving groove 63.

[0042] In this embodiment, multiple receiving slots 63 independently accommodate each PCM cooling and cold storage unit 62, which can effectively avoid mutual friction and wear between adjacent PCM cooling and cold storage units 62, extend service life. The gap between each receiving slot 63 not only helps air circulation, improves heat dissipation efficiency of the body surface, and enhances cooling comfort, but also effectively avoids excessive concentration of cold sensation, reduces discomfort caused by local low temperature, and each receiving slot also has a massage function, further improving the wearing experience.

[0043] Example 7 like Figure 5 and 6 As shown, based on Embodiment 6, the waterproof soft film 61 in this embodiment is further provided with a plurality of through holes 64, each through hole 64 being located in the gap between adjacent receiving grooves 63.

[0044] In this embodiment, the design of the through hole 64 not only improves the breathability of the waterproof soft rubber sheet 61, but also effectively reduces the risk of condensation inside the material due to temperature differences, further enhancing the wearing comfort.

[0045] Example 8 Based on Example 2, the inner layer 7 in this example is composed of a sweat-absorbing and breathable fleece surface and a waterproof and moisture-wicking smooth surface. The sweat-absorbing and breathable fleece surface is located on the outside of the pocket-shaped structure, and the waterproof and moisture-wicking smooth surface is located on the inside of the pocket-shaped structure.

[0046] In this embodiment, the sweat-absorbing and breathable fleece can quickly absorb moisture from the skin, and its soft and skin-friendly texture greatly improves the comfort of use. The waterproof and moisture-wicking smooth surface is used to prevent the condensation water generated by the PCM cooling and cold storage unit 62 during the cooling process from seeping back into the human skin through the sweat-absorbing and breathable fleece and affecting the comfort of wearing, thereby further realizing the effect of dry and wet separation.

[0047] Example 9 like Figures 1-4 As shown, based on Embodiment 1, in this embodiment, the shoulder strap 3 and waist belt 4 of the front piece 1 are integrally formed with its outer layer 5, and the shoulder strap 3 and waist belt 4 of the rear piece 2 are integrally formed with its outer layer 5. The shoulder straps 3 of the front piece 1 and the waist belt 4 of the rear piece 2 are connected by detachable connectors 9.

[0048] In this embodiment, the integrated design of the shoulder strap 3 and waist belt 4 enhances the overall structure and durability. At the same time, the detachable connector 9 enables convenient assembly and separation of the front piece 1 and the back piece 2, facilitating wearing, cleaning, and replacement, and effectively extending the overall service life of the product.

[0049] Example 10 like Figures 1-4 As shown, based on Embodiment 9, the detachable connector 9 in this embodiment is one of Velcro, strap, cord, or buckle.

[0050] In this embodiment, the Velcro, straps, ties, and buckles are not only simple in structure and easy to operate, greatly improving the convenience of putting on and taking off the vest, but also have low manufacturing costs, which is conducive to large-scale promotion and application. At the same time, the tightness can be flexibly adjusted according to the body shape of different users, effectively improving the fit and comfort of wearing the vest.

[0051] The working principle of this invention: Both the front layer 1 and the rear layer 2 are designed with a multi-layer structure to achieve a synergistic effect of heat insulation, cooling, and sweat absorption and moisture wicking. The outer layer 5 blocks external heat radiation, the middle layer 6 continuously absorbs body heat to achieve long-lasting cooling, and the inner layer 7 quickly wicks away sweat and moisture to ensure a dry and comfortable skin surface. The three-layer structure not only effectively slows down the time it takes for external heat to conduct inward, but also reduces the direct contact between external heat and the PCM cooling and cold storage layer in the middle layer 6, improving cooling efficiency and durability, thus achieving a good balance between efficient cooling and long-lasting operation.

[0052] Meanwhile, the outer layer uses police mesh fabric, which not only effectively blocks solar radiation and reflects most of the heat, reducing heat absorption in the outer layer 5, but also has a certain water-repellent property, effectively preventing raindrop penetration, and its mesh structure also ensures good breathability; the reflective strip 8 further reflects sunlight while effectively enhancing nighttime visibility, effectively improving the safety performance of wearing it; the PCM material in the middle layer 6 absorbs a large amount of heat during the phase change process, avoiding discomfort caused by sudden temperature drops, and the microchannel design of the through hole 64 promotes internal air circulation, further improving heat dissipation efficiency; the sweat-absorbing and breathable fleece surface of the inner layer 7 quickly absorbs moisture, and the waterproof and moisture-wicking smooth surface prevents condensation back seepage, achieving dry and wet separation and ensuring that the skin contact surface always stays dry; the shoulder straps 3 and waist belt 4 are connected by detachable connectors 9 for easy wearing, removal and washing. The overall structure takes into account comfort, durability and practicality, and is suitable for personal protection needs in long-term outdoor work or high-temperature environments.
