Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of sleeping appliances, in particular to a sleeping bag with carbon fibers. Background Art
[0002] Carbon fiber electric heating sleeping bags, thanks to their rapid heating, efficient heat conversion, and energy-saving and environmentally friendly features, have become a key product in modern outdoor equipment and medical care. Compared to traditional resistance wire heating technology, carbon fiber heating elements offer rapid heating (reaching the set temperature in 3-5 minutes), high thermal efficiency (heat conversion rate ≥ 98%), and exceptional flexibility (able to bend over 100,000 times), making them widely used in extreme cold environments, emergency rescue, and medical rehabilitation.
[0003] However, current carbon fiber heated sleeping bags still have significant limitations: a lack of personalized temperature control for different populations. Specifically, they offer a single-sided temperature regulation scheme: most products only support overall temperature regulation, failing to provide differentiated heating for different body parts (such as joints, core, limbs, and feet). For example, arthritis patients need to maintain a temperature in cold-sensitive areas like the knees and elbows (recommended 38-40°C), but conventional sleeping bags lack the ability to precisely regulate local temperature, potentially exacerbating pain. Women with cold constitutions often require greater warmth in the waist, abdomen, or feet, but existing products lack the ability to specifically enhance heating in these areas, resulting in a poor user experience. Furthermore, patients with external hypothermia need to rapidly raise their core body temperature (e.g., to 37-39°C in the chest and abdomen), but the uniform heating pattern of conventional sleeping bags presents drawbacks. Rapidly raising the surface temperature can cause the surface temperature to expand, leading to a return of cooler peripheral blood to the heart, further lowering the core temperature. In these situations, restoring core temperature must be prioritized.
[0004] In response to the above technical problems, how to design a sleeping bag with carbon fiber that can meet multiple application scenarios such as medical rehabilitation, outdoor first aid, and women's health, and improve user experience is a technical problem that needs to be solved urgently in the existing technology. Summary of the Invention
[0005] In order to solve the problems existing in the above background technology, the present invention provides a sleeping bag with carbon fiber, which mainly includes: It includes a cover area, a sleeping pad area, a temperature control component and a power supply; The cover area is fixedly connected to one end of the sleeping pad area, the cover area is provided with a left zipper, and the sleeping pad area is provided with a right zipper; The cover area comprises, from top to bottom, an upper cover surface layer, a thermal insulation material layer, a cover inner core layer, and an upper cover inner layer. The upper cover surface layer is made of polyurethane material.

The sleeping pad surface layer is made of a flexible material, the sleeping pad inner core layer is an electrically heated fabric made of carbon fiber yarn, and the sleeping pad bottom layer is made of polyurethane material. The temperature control component is arranged in the sleeping pad area, and the temperature control component is connected to the carbon fiber filaments and the electric heating fabric.
[0006] Furthermore, the core layer inside the cover body is provided with an upper cover area, a middle cover area, a lower cover area, and a tail cover area, and the upper cover area, the middle cover area, the lower cover area, and the tail cover area are all provided with the carbon fiber filaments, and the carbon fiber filaments in the upper cover area, the middle cover area, the lower cover area, and the tail cover area are all connected to the temperature control component.

[0007] Furthermore, the carbon fiber filaments in the electrically heated fabric in the sleeping pad area are distributed in series in an S-shape.

By adjusting the distance between two adjacent groups of carbon fiber filaments within the electrically heated fabric within the sleeping pad area, the heating efficiency of the sleeping bag can be improved and energy consumption reduced.
[0009] Furthermore, the temperature control component also includes a temperature detection device. When the real-time temperature signal detected by the temperature detection device is greater than T1, the temperature control component switches to a low-power mode; when the real-time temperature signal detected by the temperature detection device is less than T1 and greater than T2, the temperature control component switches to a power-saving mode; when the temperature detection device detects that the temperature is lower than T2, the temperature control component switches to a high-power mode. By adjusting the mode of the temperature control component through the temperature detection device, the user experience can be further enhanced.
[0010] Furthermore, it also includes a hypothermia pillow, the outer surface of the hypothermia pillow is flexible cotton cloth, the interior of the hypothermia pillow is carbon fiber filaments, the hypothermia pillow is provided with a pillow connecting part, the sleeping pad area is provided with a sleeping pad connecting part that cooperates with the pillow connecting part, and the hypothermia pillow and the sleeping pad area are detachably connected; when the hypothermia pillow and the sleeping pad area are connected through the pillow connecting part and the sleeping pad connecting part, the temperature control component can control the hypothermia pillow to generate heat, and the core temperature of the hypothermia patient can be preferentially increased through the hypothermia pillow, thereby improving the efficiency of treatment.

[0015] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be noted that relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
[0016] Example 1 This embodiment provides a sleeping bag with carbon fiber, such as Figure 1-6 As shown, it mainly includes: a cover area 1, a sleeping pad area 2, a temperature control component 3 and a power supply; the cover area 1 is fixedly connected to one end of the sleeping pad area 2, the cover area 1 is provided with a left zipper 11, and the sleeping pad area 2 is provided with a right zipper 22; the cover area 1 is composed of an upper cover surface layer 12, a thermal insulation material layer 6, a cover inner core layer 14 and an upper cover inner layer 15 from top to bottom, the upper cover surface layer 12 is made of polyurethane material, the cover inner core layer 14 includes a PVC coated cloth layer with an opening in the middle and a grid-like layer covering the upper cover. The carbon fiber filaments 5 are on the opposite sides of the PVC coated cloth layer, and the inner layer 15 of the upper cover is a flexible material; the sleeping mat area 2 is composed of a sleeping mat bottom layer 23, a thermal insulation material layer 6, a sleeping mat inner core layer 25 and a sleeping mat surface layer 26 from bottom to top, the sleeping mat surface layer 26 is a flexible material, the sleeping mat inner core layer 25 is an electrically heated fabric made of carbon fiber filaments 5, and the sleeping mat bottom layer 23 is a polyurethane material; the temperature control component 3 is arranged in the sleeping mat area 2, and the temperature control component 3 is connected to the carbon fiber filaments 5 and the electrically heated fabric.
[0017] Specifically, in this embodiment, the cover area 1 is fixedly connected to one end of the sleeping pad area 2, the cover area 1 is provided with a left zipper 11, and the sleeping pad area 2 is provided with a right zipper 22. When the user lies down in the sleeping bag, the sleeping bag can be closed by the left zipper 11 of the cover area 1 and the right zipper 22 of the sleeping pad area 2. The cover area 1 comprises, from top to bottom, an upper cover surface layer 12, a thermal insulation material layer 6, a core layer 14 in the cover body, and an upper cover inner layer 15; the sleeping pad area 2 comprises, from bottom to top, a sleeping pad bottom layer 23, a thermal insulation material layer 6, a sleeping pad inner core layer 25, and a sleeping pad surface layer 26. The sleeping pad surface layer 26 is a flexible material, wherein the upper cover surface layer 12 and the sleeping pad bottom layer 23 are both made of polyurethane material, which can be windproof and waterproof, preventing moisture in the air or moisture on the ground from entering the interior of the sleeping bag, thereby improving moisture-proof performance; the core layer 14 in the cover body comprises a PVC coated cloth layer with an opening in the middle and carbon fiber filaments 5 covered in a grid on the opposite sides of the PVC coated cloth layer, which can generate heat through the carbon fiber filaments 5. It has the special effects of fast heating, softness and foldability, and can emit 5-20μm far infrared rays after being powered on, and has the function of health care and physical therapy. A thermal insulation material layer 6 is provided between the core layer 14 of the cover body and the upper surface layer 12 of the upper cover, and a thermal insulation material layer 6 is provided in the sleeping pad area 2, wherein the thermal insulation material layer 6 can be selected from materials such as cotton wool or artificial chemical fiber, or other materials with high thermal resistance, which can improve thermal resistance and reduce the rate of heat loss; in addition, the inner layer 15 of the upper cover and the surface layer 26 of the sleeping pad are set as flexible materials, both of which are in direct contact with the human body, and can be set as wool textiles or cotton textiles or artificial fiber products or a mixture of multiple materials therein, with the characteristics of softness, lightness and comfort, thereby improving user comfort. In addition, a temperature control component 3 is provided in the sleeping pad area 2, and the temperature control component 3 is connected to the carbon fiber filaments 5 and the electric heating fabric. The heating conditions of the carbon fiber filaments 5 and the electric heating fabric can be adjusted by the temperature control component 3 to meet the needs of different users.
[0018] In some implementations of this embodiment, the core layer 14 inside the cover body is provided with an upper cover area 141, a middle cover area 142, a lower cover area 143, and a tail cover area 144. Among them, the upper cover area 141, the middle cover area 142, the lower cover area 143, and the tail cover area 144 are all provided with the carbon fiber filaments 5, and the carbon fiber filaments 5 in the upper cover area 141, the middle cover area 142, the lower cover area 143, and the tail cover area 144 are all connected to the temperature control component 3. In this embodiment, by providing the upper cover area 141, the middle cover area 142, the lower cover area 143, and the tail cover area 144 on the core layer 14 inside the cover body, the sleeping bag can have a variety of different usage modes, thereby meeting the needs of different types of users. For example, in the "female mode", for women who need to heat their abdomens, the temperature control component 3 can make the power of the carbon fiber filaments 5 in the middle cover area 142 be increased. The power of the carbon fiber filaments 5 in the upper area 141 of the cover body can be further increased through the temperature control component 3, thereby increasing the temperature of the chest and back of patients with mild hypothermia, thereby improving the efficiency of treatment. For example, in the "foot mode", the power of the carbon fiber filaments 5 in the tail of the cover body can be further increased through the temperature control component 3, thereby increasing the temperature of the feet, thereby improving the comfort of sleep. In addition, the temperature control component 3 can simultaneously increase the temperature of one or more areas of the upper area 141, the middle area 142, the lower area 143, and the tail area 144 of the cover body, that is, the user can control the heating power of one or more areas through the temperature control component 3 according to his or her own needs, thereby further improving the user's needs.
[0019] In some implementations of this embodiment, the carbon fiber filaments 5 in the electrically heated fabric in the sleeping pad area 2 are distributed in a series S-shaped manner, such as Figure 5-6As shown, specifically, the experiment shows that when the carbon fiber filaments 5 are braided in different ways, the same power is used to heat the carbon fiber filaments 5, resulting in different heating effects. Specifically, under the same power and within the same time, multiple different positions are measured and the average temperature is taken. When the carbon fiber filaments 5 are distributed in a grid shape, the temperature is higher than when the carbon fiber filaments 5 are distributed in a series S shape. That is, within the same time, the carbon fiber filaments 5 are distributed in a grid shape. Compared with the carbon fiber filaments 5 in a series S shape distribution, the carbon fiber filaments 5 can increase the temperature by a higher temperature, and the heating efficiency is higher. However, when the carbon fiber filaments 5 are distributed in a series S shape, although it takes more time to reach the same temperature compared to the carbon fiber filaments 5 in a grid shape distribution, the temperature of the multiple measurement positions tends to be consistent, while when the carbon fiber filaments 5 are distributed in a grid shape, the temperature of the multiple measurement positions differs greatly. It can be seen from this that when the carbon fiber filaments 5 are distributed in a grid shape, their heating efficiency is higher, but the temperature uniformity of different temperature measurement points in the heating area is lower. When the carbon fiber filaments 5 are distributed in a series S shape, although their heating efficiency is lower than the former, the temperature difference of their multiple measurement positions is smaller, and the temperature uniformity is higher. In this embodiment, since the sleeping pad area 2 is mainly used to heat the user's entire body, temperature uniformity is more important. Distributing the carbon fiber filaments 5 in the electrically heated fabric in the sleeping pad area 2 in a series S-shaped pattern can improve the uniformity of the temperature increase in the sleeping bag, ensuring that the temperature in each part of the sleeping bag is uniformly and slowly increased, thereby improving the user experience. In addition, the cover area 1 is provided with an upper cover area 141, a middle cover area 142, a lower cover area 143, and a rear cover area 144. The areas of these areas are relatively small, and in order to adaptively enhance heating for different areas, a grid-like covering of carbon fiber filaments 5 is provided, thereby enabling rapid heating of specific areas. At the same time, since the areas of these areas are relatively small, the disadvantage of low temperature uniformity can be ignored. In this embodiment, by providing different distribution patterns of carbon fiber filaments 5 in the cover area 1 and the sleeping pad area 2, the advantages of different distribution patterns of carbon fiber filaments 5 are utilized according to the working characteristics of different areas, which can further improve the user experience and reduce energy consumption.
[0020] In some implementations of this embodiment, when the carbon fiber filaments 5 in the electric heating fabric are distributed in a series S-shaped arrangement, the distance d between two adjacent groups of carbon fiber filaments 5 in the electric heating fabric is 1.5-2.5 cm. For example, the distance between two adjacent groups of carbon fiber filaments 5 is 2 cm. Specifically, when the carbon fiber filaments 5 in the electric heating fabric are distributed in a series S-shaped arrangement for heating, the density of the arrangement of the carbon fiber filaments 5 will affect the heating efficiency. When the voltage of the power supply is fixed, if the arrangement of the carbon fiber filaments 5 is very sparse, for example, the distance d between two adjacent groups of carbon fiber filaments 5 is greater than 2.5 cm, it will cause a large difference in the heating temperature of different areas, that is, the temperature of the area close to the carbon fiber filaments 5 is higher, while the temperature of the area between the two groups of carbon fiber filaments 5 is lower, affecting the user experience. When the distance d between the carbon fiber filaments 5 gradually decreases, in fact, the length of the carbon fiber filaments 5 in the sleeping pad area 2 is also increasing, that is, the resistance of the carbon fiber filaments 5 in the same area is also increasing. According to P=U 2 / R, then when R increases, the power P will decrease. Therefore, when the distance d between the carbon fiber filaments 5 decreases and the carbon fiber filaments are arranged more densely, the heating power of the sleeping pad area 2 will gradually decrease due to the increase in resistance, affecting the user experience. Therefore, in order to achieve the best heating effect, the distance d between the two adjacent groups of carbon fiber filaments 5 in the electric heating fabric is 1.5-2.5 cm. For example, it can be set to 1.5 cm, 1.8 cm, 2 cm, 2.5 cm, etc., so as to achieve a good heating effect and ensure sufficient heating power.
[0021] In some embodiments, the temperature control component 3 also includes a temperature detection device. When the real-time temperature signal detected by the temperature detection device is greater than T1, the temperature control component 3 switches to a low-power mode; when the real-time temperature signal detected by the temperature detection device is less than T1 and greater than T2, the temperature control component 3 switches to a power-saving mode; when the temperature detection device detects that the temperature is lower than T2, the temperature control component 3 switches to a high-power mode. Adjusting the mode of the temperature control component 3 by using the temperature detection device can further enhance the user experience. Specifically, in this embodiment, the distance d between the two adjacent groups of carbon fiber filaments 5 is set to 2cm. Multiple experiments have shown that when the power supply voltage is lower than 14V, the heating power of the carbon fiber filaments 5 will increase significantly as the power supply voltage increases. When the power supply voltage is higher than 14V and lower than 18V, as the power supply voltage increases, the heating power of the carbon fiber filaments 5 will only increase slowly due to the processing method and material of the carbon fiber filaments 5 even if the voltage is further increased. It can be seen that when the distance d between the two adjacent groups of carbon fiber filaments 5 is set to 2cm, controlling the power supply voltage at 14V can achieve the highest energy consumption ratio. When it is lower than 14V, the heating power is lower. When it is higher than 14V, although the processing power increases, the energy consumption is also better, and the cost performance is reduced. Therefore, in this embodiment, the distance d between two adjacent groups of carbon fiber filaments 5 is set to 2 cm. When the real-time temperature signal detected by the temperature detection device is greater than T1, the temperature control component 3 switches to low-power mode, that is, the power supply voltage is controlled to be lower than 14V, such as 8V, 10V, etc.; when the real-time temperature signal detected by the temperature detection device is less than T1 and greater than T2, the temperature control component 3 switches to power-saving mode, that is, the power supply voltage is controlled to 14V; when the temperature detection device detects a temperature lower than T2, the temperature control component 3 switches to high-power mode, that is, the power supply voltage is controlled to be higher than 14V, such as 16V, 18V, etc., to achieve the effect of rapid temperature increase. In this embodiment, the specific temperature values of T1, T2, and T3 can be adjusted. In addition, when the distance d between the two adjacent groups of carbon fiber filaments 5 changes, for example, when it is adjusted to other values, the voltage value of its highest energy consumption ratio will also be adjusted.
[0022] In this embodiment, the mode of the temperature control component 3 can be adjusted by the temperature detection device. This embodiment can also be mixed with the cover area 1 for adjustment. For example, the sleeping pad area 2 is set to one of the high power mode, power saving mode, and low power mode, while the cover area 1 is set to one or more of the aforementioned "female mode", "mild hypothermia mode", "foot mode", and "arthritis mode". There is no restriction in this embodiment, and the user can adjust it by himself.
[0023] In some embodiments, a hypothermic pillow 4 is also included, such as Figure 7As shown, the outer surface of the hypothermia pillow 4 is made of flexible cotton cloth, and the interior of the hypothermia pillow 4 is made of carbon fiber filaments 5. The hypothermia pillow 4 is provided with a pillow connecting portion, and the sleeping pad area 2 is provided with a sleeping pad connecting portion that cooperates with the pillow connecting portion. The hypothermia pillow 4 and the sleeping pad area 2 are detachably connected; when the hypothermia pillow 4 is connected to the sleeping pad area 2 through the pillow connecting portion and the sleeping pad connecting portion, the temperature control component 3 can control the hypothermia pillow 4 to generate heat. Specifically, for some patients with severe hypothermia, it is not enough to just rewarm the body surface, but it is necessary to prioritize core rewarming. In this embodiment, after the hypothermia pillow 4 is connected to the sleeping pad area 2 through the pillow connecting portion and the sleeping pad connecting portion, the temperature control component 3 controls the hypothermia pillow 4 to generate heat. Placing the hypothermia pillow 4 under the armpits and groin of a patient with severe hypothermia can prioritize raising the patient's core temperature, preventing lactic acid accumulation caused by rapid rewarming of the body surface, thereby improving the patient's recovery efficiency and making it more suitable for outdoor first aid scenarios.
