Description

Technical Field

[0001] This utility model relates to a sleeping bag, and more particularly to a detachable multi-layer sleeping bag, belonging to the technical field of daily necessities. Background Technology

[0002] A sleeping bag is a piece of sleep gear designed specifically for outdoor activities. It is typically filled with insulating materials such as down or synthetic fibers and features a zipper or buckle closure to provide a windproof and warm sleeping environment. Its core function is to ensure even distribution of the filling through techniques such as lining cuts, preventing cold spots from forming.

[0003] Traditional sleeping bags are typically one-piece structures, which have certain drawbacks. For example, each sleeping bag is basically assigned a single temperature rating, making it unable to flexibly adapt to varying environmental temperatures. The limited temperature rating also results in poor adaptability. Users who need to cope with different seasons or environments with large temperature differences often need to purchase multiple sleeping bags with different temperature ratings, which is costly and inconvenient to carry. Frequent washing can damage the filling and down-proof fabric, affecting their lifespan, and cleaning and maintenance are extremely inconvenient. In addition, traditional sleeping bags cannot provide differentiated warmth for different parts of the body due to temperature differences, resulting in low thermal efficiency and poor comfort. Although some sleeping bags offer removable padding, they do not achieve true zoning management and flexible warmth coordination in their structure.

[0004] To address the above issues, it is necessary to improve the structure of sleeping bags to enhance their usability. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned problems by providing a detachable multi-layer sleeping bag, which improves the problems of single temperature rating, poor adaptability, inconvenience in cleaning and maintenance, and high usage costs, thereby improving its performance.

[0006] The technical solution of this utility model is: a detachable multi-layer sleeping bag, including a first sleeping bag body and a second sleeping bag body, both of which are made of windproof, waterproof and breathable fabric. The first sleeping bag body and the second sleeping bag body are fixedly connected along one side to form an integral connection side; the other opposite side of the first sleeping bag body and the second sleeping bag body are movably connected by a hidden zipper assembly to form an opening and closing side. The first sleeping bag body and the second sleeping bag body together form a sleeping bag structure for accommodating the user by closing the hidden zipper assembly; the interior of both the first sleeping bag body and the second sleeping bag body is provided with one or more detachable thermal insulation layers.

[0007] Furthermore, in the aforementioned detachable multi-layer sleeping bag, the outer or inner surface of the first sleeping bag body is provided with a chest temperature control zone corresponding to the human chest, an abdominal temperature control zone corresponding to the human abdomen, and a first foot temperature control zone corresponding to the human feet, arranged sequentially from top to bottom.

[0008] Furthermore, in the aforementioned detachable multi-layer sleeping bag, the outer or inner surface of the second sleeping bag body is provided with a back temperature control zone corresponding to the back of the human body and a second foot temperature control zone corresponding to the feet of the human body, from top to bottom.

[0009] Furthermore, in the aforementioned detachable multi-layer sleeping bag, a sleeping cap is provided at the upper end of the first sleeping bag body, and the sleeping cap is movably connected to the upper end of the first sleeping bag body via a Velcro fastener.

[0010] Furthermore, in the aforementioned detachable multi-layer sleeping bag, the first foot temperature control area on the first sleeping bag body and the second foot temperature control area on the second sleeping bag body together form a complete foot receiving cavity when the sleeping bag body is closed.

[0011] Furthermore, in the aforementioned detachable multi-layer sleeping bag, the detachable insulating structure layer is a multi-layer structure, including an outer layer, a middle layer, and an inner layer, each layer being made of different insulating materials and capable of being independently disassembled and assembled.

[0012] Furthermore, in the aforementioned detachable multi-layer sleeping bag, the chest temperature control zone, abdominal temperature control zone, first foot temperature control zone, back temperature control zone, and second foot temperature control zone are independently controlled zoned electric heating units. Each unit is equipped with an electric heating element, a temperature sensor, and an independent power interface. Each unit is connected to a central controller via a flexible circuit. The central controller has a user interface for adjusting the temperature of each zone and the control mode.

[0013] Compared with existing technologies, by adopting the technical solution of this utility model, by adding, subtracting or replacing the insulation layer, the sleeping bag can cover various temperature scales from hot summer to cold winter, solving the limitation of one sleeping bag corresponding to one temperature scale. Moreover, modular and zoned temperature control is implemented for different parts of the body to meet their temperature needs. The zoned insulation design allows users to configure according to their own physiological characteristics, effectively solving problems such as cold feet and overheated back, and improving overall sleep comfort.

Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings to make it easier to understand and master. The sleeping cap 6, Velcro 7, and hidden zipper assembly 8 involved are all commonly used components that are generally recognized by those skilled in the art, and there are no special requirements for them in this case.

[0022] like Figures 1-4 As shown, this utility model provides a detachable multi-layer sleeping bag, including a first sleeping bag body 1 and a second sleeping bag body 2. The outer fabric of both is made of windproof, waterproof and breathable fabric. The first sleeping bag body 1 and the second sleeping bag body 2 are fixedly connected along one side to form an integral connection side. The other opposite side of the first sleeping bag body 1 and the second sleeping bag body 2 are movably connected by a hidden zipper assembly 8 to form an opening and closing side.

[0023] According to the technical solution of this utility model, the first sleeping bag body 1 and the second sleeping bag body 2 together form a sleeping bag structure for the user to accommodate by closing the hidden zipper assembly 8; the interior of the first sleeping bag body 1 and the second sleeping bag body 2 is provided with one or more detachable thermal insulation layers (if the interior of the first sleeping bag body 1 and the second sleeping bag body 2 is not filled with thermal insulation layers, it can be freely switched between multiple modes such as single sleeping bag, double sleeping bag or quilt to meet more scenario needs); the outer or inner surface of the first sleeping bag body 1 is provided with a chest temperature control zone 9 corresponding to the human chest, an abdominal temperature control zone 10 corresponding to the human abdomen, and a first foot temperature control zone 11 corresponding to the human feet in sequence from top to bottom; the outer or inner surface of the second sleeping bag body 2 is provided with a back temperature control zone 12 corresponding to the human back and a second foot temperature control zone 13 corresponding to the human feet in sequence from top to bottom.

[0024] Preferably, in the above structure: a sleeping cap 6 is provided at the upper end of the first sleeping bag body 1, and the sleeping cap 6 is movably connected to the upper end of the first sleeping bag body 1 by a Velcro 7, which is suitable for keeping the head warm.

[0025] Preferably, in the above structure: the first foot temperature control zone 11 on the first sleeping bag body 1 and the second foot temperature control zone 13 on the second sleeping bag body 2 together form a complete foot receiving cavity when the sleeping bag body is closed, so as to improve the foot warmth retention efficiency.

[0026] Preferably, such as Figure 5 As shown in the above structure: the detachable insulation layer is a multi-layer structure, including an outer layer 3, a middle layer 4 and an inner layer 5. Each layer is made of different insulation materials and can be disassembled and assembled independently.

[0027] Specifically, in the above-mentioned insulation structure, without the use of local heating, using the inner layer 5 alone results in a temperature range of approximately 15℃ to 20℃+ (suitable for summer / indoor use); using the middle layer 4 alone results in a temperature range of approximately 0℃ to 10℃ (suitable for late spring / early autumn); using the inner layer 5 and the middle layer 4 results in a temperature range of approximately -5℃ to 5℃ (suitable for spring / autumn / high-altitude summer); using the middle layer 4 and the outer layer 3 results in a temperature range of approximately -10℃ to 0℃ (suitable for winter / high-altitude use); and using the inner layer 5, the middle layer 4, and the outer layer 3 results in a temperature range of approximately -20℃ to -10℃ (suitable for extremely cold environments). By combining different layers, the insulation structure of the sleeping bag can achieve extremely high flexibility and a wide temperature range coverage.

[0028] More specifically, the chest temperature control zone 9, the abdominal temperature control zone 10, the first foot temperature control zone 11, the back temperature control zone 12, and the second foot temperature control zone 13 are independently controlled zoned electric heating units. Each unit is equipped with an electric heating element, a temperature sensor, and an independent power interface. Each unit is connected to a central controller via a flexible circuit. The central controller has a user interface for adjusting the temperature and control mode of each zone, so as to intelligently adjust the local temperature of the human body.

[0029] The key technical aspect of this invention lies in the combination of the multi-layered sleeping bag, the detachable thermal insulation layer within each sleeping bag, and the modular temperature control zone. Figures 1-4 The focus of the exhibition is on the components involved in the detachable sleeping bag. Figure 5The diagram shows the specific structure of the insulation layer. Depending on the ambient temperature and user needs, appropriate quantities and / or types of insulation layers are selected and installed inside the first sleeping bag body 1 and the second sleeping bag body 2. For components such as the sleeping cap 6, Velcro 7, and concealed zipper assembly 8, those skilled in the art can perform conventional setups based on existing technology; this case does not have special requirements regarding their model selection or combination.

[0030] Thus, by adopting the technical solution of this utility model, before using the sleeping bag, the user first needs to configure the insulation performance of the sleeping bag according to the ambient temperature, personal cold resistance and usage mode. The first sleeping bag body 1 and the second sleeping bag body 2 are fully unfolded, and the selected number of insulation structural layers (the corresponding inner layer 5, middle layer 4 and outer layer 3 are selected according to the needs) are installed into the interior of the inner layer 5, middle layer 4 and outer layer 3 respectively through the connectors (such as zippers, Velcro, straps or snaps) set on their edges, ensuring that the insulation structural layers are laid flat without curling or wrinkles, so as to achieve the best insulation effect. Then, lay the unfolded first sleeping bag body 1 and second sleeping bag body 2 flat on the sleeping mat or moisture-proof mat. Pull the zipper assembly 8 to close the movable connecting side of the first sleeping bag body 1 and the second sleeping bag body 2, so that the two are combined into a complete sleeping bag. At this time, the first foot temperature control zone 11 and the second foot temperature control zone 13 together form a complete foot cavity (the feet are the extremities that are easily cold. Users can increase the thickness of the first foot temperature control zone 11 and the second foot temperature control zone 13 at the same time to provide the feet with insulation protection far exceeding that of other parts of the body). The user enters the sleeping bag through the opening of the zipper assembly 8. After lying down completely, the user's chest, abdomen, and instep naturally fall within the chest temperature control zone 9, abdomen temperature control zone 10, and first foot temperature control zone 11 of the first sleeping bag body 1. The user's back and soles naturally fall within the back temperature control zone 12 and second foot temperature control zone 13 of the second sleeping bag body 2. The user interface uses the central controller to adjust the temperature of each zone to improve warmth and comfort. If the head feels cold, the detachable sleeping cap 6 can be attached to the first sleeping bag body 1 via Velcro 7 and worn on the head. After using the sleeping bag, the above steps are reversed: first, open the zipper assembly 8 to unfold the sleeping bag, then remove the insulation layers from the inside of the first sleeping bag body 1 and the second sleeping bag body 2 respectively. Roll up or compress each insulation layer and each bag body separately for storage to save space.

[0031] As can be seen from the above description, compared with the prior art, by adopting the technical solution of this utility model, by adding, removing, or replacing the insulation layer, the sleeping bag can cover various temperature scales from hot summer to cold winter, solving the limitation of one sleeping bag corresponding to one temperature scale. Moreover, modular and zoned temperature control is implemented according to the different temperature needs of different parts of the body. The zoned insulation design allows users to configure according to their own physiological characteristics, effectively solving problems such as cold feet and overheated back, and improving overall sleep comfort. In addition, the components in the detachable sleeping bag structure can be used individually, which can also effectively improve the efficiency of cleaning and maintenance of the sleeping bag, avoid frequent washing, and effectively extend the service life of the sleeping bag.

[0032] The technical solution, working process and implementation effect of this utility model have been described in detail above. It should be noted that the described example is only a typical example of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
