Description

Technical Field

[0001] This utility model belongs to the field of cooling clothing technology, and in particular relates to a multifunctional cooling protective suit. Background Technology

[0002] In hot summer or high-temperature environments, when the ambient temperature exceeds 32℃, the body's thermoregulation system will be the first to show a significant stress response. The body surface will feel hot, and at the same time, it will be difficult to concentrate, the mind will be easily fatigued, the flexibility of limbs will also decrease, and the overall physical comfort will be greatly reduced.

[0003] As in existing technology, Chinese utility model patent CN201700436U describes a multi-functional protective suit for mines. The inner side of the protective jacket has four or more pockets, each containing a cold storage bag. This cold storage bag is small, lightweight, and environmentally friendly, providing uniform, stable, and long-lasting cooling to meet human comfort requirements. The outer insulation plate and the cold storage bag also provide efficient insulation and heat preservation, maintaining a cooling temperature of 5-20℃ for 4-6 hours in a 30℃ environment. The outer side of the protective jacket has one or more self-illuminating warning signs that can continuously emit light for more than 12 hours in the dark. The luminous intensity and duration are 30-50 times that of traditional luminescent materials, exhibiting excellent stability and weather resistance. The protective suit also possesses high antistatic properties, good breathability, and high conductivity.

[0004] While existing technologies achieve cooling through cold storage bags, their fixed-size design can lead to issues such as the bag being too tight for users with large waist / chest circumference deviations, affecting their comfort, or too loose, reducing its cooling effect. This makes it unsuitable for people of different body types. Furthermore, the cold storage material inside the bag is a single unit; therefore, when placed inside the pockets of protective clothing, it can hinder the worker's movements, thus reducing the comfort of the protective clothing during work. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the above-mentioned technical problems, this utility model proposes a multi-functional cooling protective suit.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: multiple internal storage pockets are sewn inside the main body of the protective suit, and each internal storage pocket contains a cold storage bag and a buffer bag for delaying cooling. The cold storage bag is placed inside the buffer bag for delaying cooling. The cold storage bag is provided with a dividing line, which allows the cold storage bag to be folded. The main body of the protective suit is provided with an elastic adjustment belt along the waist circumference. The front of the main body of the protective suit is provided with Velcro. The two ends of the elastic adjustment belt are respectively fixedly connected to the Velcro.

[0007] Optionally, the cushioning bag for delaying cooling is made of cotton or transparent TPU material, with three sides closed and the remaining side forming an opening to create a containment space that is open at one end and closed at the other three.

[0008] Optionally, when the cushioning bag is made of transparent TPU material, multiple airbags are evenly distributed on both sides of the cushioning bag along the thickness direction, and ventilation holes are opened in the gaps between adjacent airbags.

[0009] Optionally, the Velcro has a hook side and a loop side. The loop side is fixed to the inside of the protective clothing body, while the hook side moves with the elastic adjustment band. The area of ​​the loop side is larger than that of the hook side.

[0010] Optionally, each internal storage pocket opening has a Velcro closure smaller than or equal to the pocket edge.

[0011] Optionally, the main body of the protective suit is connected to a protective helmet via a detachable connecting component on the back of the collar, and a dust mask is connected to the outside of the protective helmet via a detachable connecting component. The top of the inner side of the protective helmet is provided with a layer, and inside the layer are placed a cold storage bag and a cushioning bag that matches the size of the protective helmet.

[0012] Optionally, internal storage pockets are distributed on both sides inside the main body of the protective suit, with four pockets on the inner wall near the back and two pockets on the inner wall near the front.

[0013] Optionally, sleeves are provided on both sides of the main body of the protective suit. The sleeves are made of the same mesh, porous or fine-pore material as the main body of the protective suit, and the sleeves are connected to the main body of the protective suit by a detachable connecting component.

[0014] Optional, detachable connecting components include Velcro, zippers, or snaps.

[0015] Optionally, the outer wall of the protective suit body is equipped with reflective strips, and the protective suit body is equipped with multiple external storage pockets.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. By incorporating an elastic adjustment band along the waistline on the exterior of the protective suit, combined with a Velcro design where the surface area of ​​the loop is larger than the hook area, multiple tightness adjustments can be achieved to accommodate different body types and effectively solve the problem of fixed sizes in existing technologies. Furthermore, the elastic adjustment adapts to the body's movements, improving limb flexibility by over 30% compared to existing technologies and significantly optimizing wearing comfort.

[0018] 2. The design of the dividing lines allows for adaptive folding during staff movement, thus making the internal cooling material fit the human body more closely.

[0019] 3. By placing a cooling bag inside the interlayer, the worker's head can be kept cooler, thus reducing the perceived temperature. This effect further lowers the body temperature. The protective helmet, connected by a detachable component, can be installed or removed as needed.

[0020] 4. By setting up a buffer bag, a buffer layer is formed, which can not only effectively block the cold energy inside the cold storage bag from being rapidly conducted to the outside to prevent frostbite, but also absorb the impact from the outside when the cold storage bag is hit or squeezed.

[0021] 5. By attaching a dust mask to the safety helmet via a detachable connecting component, the flexibility of the protective clothing is improved, making it adaptable to a variety of different working environments.

[0022] 6. External storage pockets are provided on the front and abdomen of the protective suit to allow for the categorized storage of personal items such as mobile phones and tools; the Velcro openings of the internal storage pockets allow for quick access to cushioning bags and cold storage bags, which is convenient to operate and prevents the cushioning bags and cold storage bags from shifting during activities.

[0023] 7. The detachable connecting components allow the sleeves on both sides to be installed or not, depending on the actual usage environment and the needs of the staff. Removing the sleeves in high-temperature environments can improve heat dissipation efficiency, while installing the sleeves in outdoor environments can provide anti-scratch and insect-proof functions.

[0024] 8. The reflective strips sewn onto the outer wall of the back of the protective suit are made of PVC microprism material, which has a retroreflective coefficient that is much higher than that of existing self-luminous warning signs. At night or in low light conditions, they can form a clear visual warning signal after being illuminated by external light, which can effectively remind surrounding vehicles or personnel to pay attention and significantly reduce safety hazards in high-temperature outdoor work scenarios.

Detailed Implementation

[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0037] like Figure 1-2 The diagram shows a preferred embodiment of a multifunctional cooling protective suit. This multifunctional cooling protective suit includes sleeves 102 on both sides of the main body 100. A detachable connecting component 101 is provided between the sleeves 102 and the main body 100, allowing the sleeves 102 to be detached. A reflective strip 108 is provided on the outer wall of the main body 100. Velcro 103 is provided on the front of the main body 100. Multiple external storage pockets 104 are provided on the main body 100. In this embodiment, the detachable connecting component 107 allows the sleeves 102 to be selected for use based on the actual environment and worker needs. The reflective strip 108 serves as a warning, increasing safety during construction.

[0038] like Figure 1-2 As shown, in order to make the sleeves 102 on both sides more comfortable to wear, in this embodiment, the sleeves 102 are made of mesh, porous or finely porous material. The mesh, porous or finely porous material makes the breathability better and the wearing more comfortable.

[0039] like Figure 1-2 As shown, in order to make the protective suit body 100 adaptable to people of different body types, in this embodiment, the protective suit body 100 is provided with two elastic adjustment straps 105 along the waist circumference. The two ends of the elastic adjustment straps 105 are fixedly connected to Velcro 103. In this embodiment, the elastic adjustment straps 105 on the outside of the protective suit body 100 are adjusted for tightness through Velcro 103. When the wearer's body shape changes, the elastic adjustment straps 105 can stretch and contract with the waist curve, and the Velcro 105 can be moved laterally to change the circumference of the closure, so that a good fit can still be maintained even when the size is not suitable, thereby improving the comfort and cooling effect of wearing the protective suit.

[0040] like Figure 2 , Figure 5 , Figure 6 As shown, this is a schematic diagram of the cooling cap structure in this embodiment. The protective suit body 100 is connected to the protective safety helmet 107 via a detachable connecting component 101 on the back of the collar. The outer side of the protective safety helmet 107 is connected to the dust mask 111 via a detachable connecting component. The inner top of the protective safety helmet 107 is provided with a layer, and a cold storage bag 106 is placed inside the layer. In this embodiment, by placing the cold storage bag 106 inside the layer, the worker's head can be cooler, thereby reducing the perceived temperature and achieving a cooling effect. The dust mask 111 is provided on the outer side of the protective safety helmet 107 via the detachable component 101, which expands the application scenarios of this utility model. The protective safety helmet 107 and the dust mask 111 connected by the detachable connecting component 101 can be installed or removed according to actual needs.

[0041] like Figure 2 , Figure 5 , Figure 6 As shown, in order to improve the cooling effect of the protective helmet 107, in this embodiment, the protective helmet 107 is made of a mesh, porous or finely porous material, which makes the protective helmet 107 more breathable.

[0042] It is worth noting that the aforementioned detachable connecting component 107 is a Velcro 103, a zipper, or a snap, and in this embodiment, a Velcro 103 is preferred.

[0043] like Figure 3-4As shown, this is a schematic diagram of the internal structure of the cooling protective suit in this embodiment. The main body 100 of the protective suit has multiple internal storage pockets 110 sewn inside, and each internal storage pocket 110 has a Velcro closure 103 of equal length to the pocket edge at its opening. Each internal storage pocket 110 contains a cushioning bag 112 and a cold storage bag 106. In this embodiment, the placement of the cushioning bag 112 and cold storage bag 106 inside the multiple internal storage pockets 110 allows for cooling of the interior of the protective suit 100, thus reducing the perceived temperature. In use, the cold storage bag 106 is first frozen for 10-12 hours. After freezing, the cold storage bag 106 is placed inside the cushioning bag 112, and finally, the cushioning bag 112 is placed inside the internal storage pocket 110. The protective suit can then be worn for cooling. Cooling time: At an ambient temperature of 30℃, it can maintain a body temperature (20-28℃) for 6-8 hours.

[0044] It is worth noting that, in this embodiment, the internal storage 110 pocket has a length of 17-22 cm, a width of 14-20 cm, and an opening width of 4-8 cm; the cushioning bag 112 has a length of 16-21 cm, a width of 13-19 cm, and a thickness of 1.5-3.5 cm; and the cold storage bag 106 has a length of 15-20 cm, a width of 12-18 cm, and a thickness of 1-3 cm.

[0045] It is worth noting that the internal storage pockets 110 are distributed on both sides inside the protective suit body 100, with 4 pockets on the inner wall near the back of the protective suit body 100 and 2 pockets on the inner wall near the front of the protective suit body 100.

[0046] like Figure 2-3 As shown, in order to make the cold storage material inside the cold storage bag 106 fit the human body better, in this embodiment, the cold storage bag 106 is provided with a dividing line 109. The dividing line 109 allows the cold storage bag 106 to be folded. In this embodiment, the dividing line 109 can be set to fold adaptively when the staff moves, thereby making the cold storage material inside fit the human body better.

[0047] It is worth noting that the aforementioned cold storage material is a highly flexible phase change cold storage material, which has a large latent heat of phase change and a suitable phase change temperature. It will not harden after freezing and can maintain a suitable softness. It is described in Chinese invention patent (CN115260771B) and is existing technology.

[0048] like Figure 7 As shown, it is a schematic diagram of the buffer bag structure in this embodiment. The buffer bag 112 is made of cotton material or transparent TPU material, with three sides closed and the remaining side forming an opening to form a receiving space with one end open and three ends closed, and the space is used to accommodate the cold storage bag.

[0049] In one specific embodiment of this utility model, when the cushioning bag 112 is made of cotton, one side of the cushioning bag 112 along its thickness direction has a single-layer cotton structure (first side), and the other side has a double-layer cotton structure (second side). In this embodiment, the softness of the cotton cushioning bag 112 allows it to conform to the curves of the human body. When the cold storage bag 106 is placed into the three-sided enclosed space, the physical constraint formed by the closed sides prevents the cold storage bag 106 from lateral displacement in the horizontal plane, while the open side allows for fine-tuning of its position in the vertical direction. During human activity, the elastic deformation of the cotton material can absorb some of the impact of movement, preventing the cold storage bag 106 from colliding hard with the body surface. The structural design of the open end allows the cold storage bag to adjust its insertion depth according to body shape differences, while maintaining a constant contact area with the body surface. The second side of the double-layer cotton structure provides better heat insulation and cushioning, preventing direct conduction of the low temperature of the cold storage bag 106, while the first side of the single-layer cotton structure retains a certain heat dissipation efficiency, ensuring a uniform release of the cold storage effect.

[0050] In another specific embodiment of this utility model, when the cushioning bag 112 is made of TPU material, both sides of the cushioning bag 112 along the thickness direction adopt independent TPU airbag structures. The cushioning bag is formed into an integrated structure through an overall edge hot-press sealing process, forming a cold storage bag containing space with one end open and the other three ends closed. The thickness of the airbags on both sides is the same, 8-12 mm, and the internal gas content is 40-70%, preventing rupture under pressure while retaining its cushioning properties. Ventilation holes with a diameter of 6-9 mm are opened between adjacent airbags on each side. The edges of the ventilation holes are reinforced by secondary hot pressing to prevent air leakage due to the openings. In this embodiment, the double-sided TPU airbags conform to the human body while adapting to deformation without causing pressure. While resisting friction and impact and protecting the cold storage bag 106, they also protect the human body from hard contact with the cold storage bag 106, and prevent discomfort or frostbite caused by direct contact between the human body and the cold storage bag 106. The double airbags provide uniform cushioning and reduce the displacement of the cold storage bag 106 during activities. The airbags on the side closest to the body have ventilation holes, which can provide good breathability while ensuring heat insulation and cushioning.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
