Description

Technical Field

[0001] This utility model relates to the field of sleeping bag technology, specifically to an outdoor camping warm sleeping bag. Background Technology

[0002] Outdoor camping sleeping bags are pieces of equipment designed to provide warmth and comfortable sleep in outdoor environments. They typically consist of an outer layer of windproof and waterproof fabric, an inner layer of soft, skin-friendly material, and a middle layer of insulating filling (such as down or synthetic cotton). They are often mummy-shaped (fitting to the body's contours) or envelope-shaped (more spacious) to reduce heat loss and enhance warmth.

[0003] Existing traditional thermal sleeping bags typically only provide insulation, relying on filling materials such as down or synthetic fibers to create a static insulating air layer to slow down heat loss from the body. However, this design has significant limitations: it cannot dynamically adjust thermal performance according to changes in ambient temperature, the user's activity level, or metabolic rate, easily leading to uneven heat distribution and even localized insulation failure, affecting overall comfort and sleep quality. Utility Model Content

[0004] The purpose of this utility model is to provide an outdoor camping warm sleeping bag to solve the problem mentioned in the background art that traditional warm sleeping bags rely solely on down or synthetic fiber cotton to form a static insulation layer, passively slowing down heat loss, which easily leads to uneven heat distribution and local insulation failure, affecting comfort and sleep quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an outdoor camping warm sleeping bag, comprising a sleeping bag body, a groove on the inner side of the sleeping bag body, a rotating rod rotatably connected to the inner cavity of the groove, a roll fixedly connected to the outer surface of the rotating rod, a blanket installed on the outer surface of the roll, a first Velcro fastener installed on the side of the blanket away from the roll, a second Velcro fastener that is adhered to the first Velcro fastener on the inner side of the sleeping bag body, and a protective component installed on the outer surface of the sleeping bag body.

[0006] Furthermore, the protective component comprises, from the outside to the inside, a first outer layer, an adhesive layer, a second outer layer, a thermal insulation layer, a breathable cavity, a breathable layer, and a sterilization layer, with an adhesive layer adhered to the bottom of the first outer layer.

[0007] Furthermore, a second outer layer is adhered to the bottom of the adhesive layer, and a thermal insulation layer is adhered to the bottom of the second outer layer.

[0008] Furthermore, a breathable layer is installed at the bottom of the insulation layer, and several breathable cavities are formed between the breathable layer and the insulation layer.

[0009] Furthermore, a sterilization layer is adhered to the bottom of the breathable layer, and the bottom of the sterilization layer is adhered to the outer surface of the sleeping bag body.

[0010] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0011] This invention achieves a synergistic effect of active wrapping and passive protection through a wrapping function consisting of a blanket, a roll, and a rotating rod, combined with a composite structure comprised of multiple protective components (including a double-layered windproof outer layer, a sealing adhesive layer, a high-efficiency insulation layer, a breathable cavity, and a breathable layer). Users can manually adjust the blanket's coverage area according to their needs, dynamically optimizing localized insulation. Simultaneously, the multi-layered protection system effectively blocks the intrusion of cold air, locks in body heat, and wicks away moisture, significantly improving overall warmth and microclimate comfort. This design balances flexibility and adaptability, allowing users to obtain an efficient, stable, and personalized warmth experience in different ambient temperatures and usage scenarios.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] Example: An outdoor camping thermal sleeping bag, such as Figures 1-4 As shown, the sleeping bag includes a sleeping bag body 1. A groove 2 is provided on the inner side of the sleeping bag body 1. A rotating rod 3 is rotatably connected to the inner cavity of the groove 2. The groove 2 is located on the inner side of the sleeping bag body 1 to achieve the purpose of installing the rotating rod 3. A roll 4 is fixedly connected to the outer surface of the rotating rod 3. A blanket 5 is installed on the outer surface of the roll 4. For example, the blanket 5 can be completely covered on the outer surface of the roll 4 for use, thereby achieving a double warmth effect for the user through the blanket 5.

[0021] like Figures 1-4 As shown, a first Velcro 6 is installed on the side of the blanket 5 away from the roll 4, and a second Velcro 7, which is attached to the first Velcro 6, is installed on the inner side of the sleeping bag body 1. This allows for a quick connection between the blanket 5 and the sleeping bag body 1, facilitating the covering of the user. A protective component 8 is installed on the outer surface of the sleeping bag body 1. The protective component 8, from the outside to the inside, includes a first outer layer 81, an adhesive layer 83, a second outer layer 82, a thermal layer 84, a ventilation cavity 85, a ventilation layer 86, and a sterilization layer 87. An adhesive layer 83 is attached to the bottom of the first outer layer 81, and a second outer layer 82 is attached to the bottom of the adhesive layer 83. The first outer layer 81 and the second outer layer 82 are specifically made of high-strength nylon fabric, which provides protection... With excellent water and wind resistance, it effectively blocks condensation inside the tent and rainwater from the outside. It is highly abrasion-resistant, suitable for harsh outdoor environments, lightweight, and highly compressible, meeting the needs of mountaineering and camping. The second outer layer 82 is made of Toray nylon, forming a double waterproof barrier with the first outer layer 81, ensuring the sleeping bag stays dry in extreme weather. Toray nylon is a commonly used material in high-end outdoor brands. The two layers work together to provide better wind and water resistance than a single outer layer. The adhesive layer 83 is a silicone coating, used to bond the first outer layer 81 and the second outer layer 82, ensuring a complete seal between them and preventing cold air from entering through the seams. The silicone is elastic and will not affect the sleeping bag's compressibility.

[0022] like Figures 2-4As shown, the bottom of the second outer layer 82 is covered with a warming layer 84. This warming layer 84 is made of goose down, selected high-loft goose down with a loft of over 700FP and a down content of 90%. It has an excellent warmth-to-weight ratio, providing optimal warmth for the same weight. It is compact, easy to carry, and provides long-lasting warmth. At the bottom of the warming layer 84 is a breathable layer 86, made of high-density nylon fabric with a density of over 200T. The surface is treated with graphene printing for antibacterial properties, ensuring good breathability, preventing moisture buildup, and keeping the inside of the sleeping bag dry. The graphene printing also has antibacterial and warming properties. With anti-static properties, it is comfortable against the skin, soft and skin-friendly, avoiding skin irritation. Several ventilation chambers 85 are opened between the breathable layer 86 and the insulating layer 84 to achieve air circulation and prevent overheating. A sterilization layer 87 is attached to the bottom of the breathable layer 86, and the bottom of the sterilization layer 87 is attached to the outer surface of the sleeping bag body 1. The sterilization layer 87 is made of zinc-based antibacterial material. While maintaining good breathability, the sleeping bag can also continuously inhibit bacterial growth and prevent odors and bacteria from growing inside the sleeping bag body 1, making it particularly suitable for long-term camping.

[0023] Specifically, the user can manually pull the blanket 5 to extend it, causing the roll 4 to rotate synchronously around the rotating rod 3. Once the blanket 5 is unfolded to the appropriate position, the first Velcro 6 and the second Velcro 7 are fastened together, tightly wrapping the blanket 5 around the user's body to achieve personalized wrap-around warmth and significantly improve local heat retention.

[0024] Meanwhile, the external protective structure of the sleeping bag body 1 works synergistically: the first outer layer 81 and the second outer layer 82 first form a double physical barrier against the cold air from the outside, effectively preventing the cold air from penetrating into the sleeping bag; the two are sealed together by the adhesive layer 83, further enhancing the windproof and cold-resistant performance. On this basis, the inner insulating layer 84 provides the core heat insulation function, locking in the heat emitted by the body.

[0025] To avoid stuffiness and moisture buildup, the structure also integrates a breathable cavity 85 and a breathable layer 86, which together create a micro-circulation air channel. While maintaining efficient warmth, it promotes moisture removal and air circulation, achieving a comfortable experience of "warmth without stuffiness and sweating".

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
