Abstract
Description
Technical Field
[0001] This utility model relates to the field of comforter cores, specifically to a bidirectional phase change temperature regulating comforter core. Background Technology
[0002] The comforter core refers to the part between the inner filling material of the comforter and the outer cover. It can also be understood as the internal structure or inner filling of the comforter. It is a key part that constitutes the main body of the comforter. It is usually filled with warming materials such as cotton, down, chemical fibers, wool, silk, camel hair, etc. The main function of the comforter core is to provide a comfortable sleeping environment and ensure that the human body can get enough warmth during sleep.
[0003] However, traditional comforters often have the problem of balancing warmth and breathability. They cannot effectively retain heat in cold environments, and cannot dissipate heat in time when it is hot. This causes users to frequently toss and turn or wake up due to temperature discomfort during sleep, which seriously affects sleep quality.
[0004] Therefore, it is necessary to invent a bidirectional phase change temperature-regulating comforter. Utility Model Content
[0005] Therefore, this utility model provides a bidirectional phase change temperature-regulating quilt core, which integrates phase change material into the quilt core and utilizes its unique property of absorbing or releasing heat through a change of state at a specific temperature to achieve automatic temperature regulation of the quilt core. This breaks through the limitation of traditional quilt cores that rely solely on the heat retention or breathability of the material itself to regulate temperature, thereby solving the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a bidirectional phase change temperature regulating quilt core, comprising a core layer, a first insulation layer fixed to the top of the core layer, a second insulation layer fixed to the bottom of the core layer, a first bidirectional phase change temperature regulating layer fixed to the bottom of the second insulation layer, and a second bidirectional phase change temperature regulating layer fixed to the top of the first insulation layer.
[0007] Preferably, the first insulation layer is made of Tencel cotton wadding, the first insulation layer has a size of 53*53cm, and the amount of the first insulation layer is 190g / ㎡-220g / ㎡.
[0008] Preferably, the second insulation layer is made of DuPont cotton wadding, the second insulation layer has a size of 53*53cm, and the amount of the second insulation layer is 190g / ㎡-220g / ㎡.
[0009] Preferably, both the first bidirectional phase change temperature regulating layer and the second bidirectional phase change temperature regulating layer are configured as phase change temperature regulating cotton wadding, the specifications of the first bidirectional phase change temperature regulating layer and the second bidirectional phase change temperature regulating layer are both 53*53cm, and the dosage of the first bidirectional phase change temperature regulating layer and the second bidirectional phase change temperature regulating layer are both 190g / ㎡-220g / ㎡.
[0010] The beneficial effects of this utility model are as follows: By using the core layer, the first insulation layer, the second insulation layer, the first bidirectional phase change temperature regulating layer, and the second bidirectional phase change temperature regulating layer in combination, the phase change material absorbs or releases heat by undergoing a physical change at a specific temperature, thus automatically regulating the temperature inside the quilt core. When the body temperature rises, the phase change material absorbs and stores heat; when the body temperature drops, the phase change material releases the previously stored heat, thereby always keeping the temperature inside the quilt core within a comfortable range for the human body. This effectively solves the technical problem of poor temperature regulation capability of traditional quilt cores, bringing users a comfortable and stable sleeping environment.

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0016] Please refer to the appendix. Figures 1-3 The present invention provides a bidirectional phase change temperature regulating quilt core, including a core layer 1, a first heat insulation layer 2 fixed to the top of the core layer 1, a second heat insulation layer 3 fixed to the bottom of the core layer 1, a first bidirectional phase change temperature regulating layer 4 fixed to the bottom of the second heat insulation layer 3, and a second bidirectional phase change temperature regulating layer 5 fixed to the top of the first heat insulation layer 2.
[0017] Furthermore, the first insulation layer 2 is made of Tencel cotton batting, the first insulation layer 2 has a size of 53*53cm, and the amount of the first insulation layer 2 is 190g / ㎡-220g / ㎡. It should be noted that the amount of Tencel cotton batting is preferably set to 200g / ㎡, which can play a role in keeping warm.
[0018] Furthermore, the second insulation layer 3 is made of DuPont fleece wadding, the size of the second insulation layer 3 is 53*53cm, and the amount of the second insulation layer 3 is 190g / ㎡-220g / ㎡. It should be noted that the amount of DuPont fleece wadding is preferably set to 200g / ㎡, which can play a role in heat preservation.
[0019] Furthermore, both the first bidirectional phase change temperature regulating layer 4 and the second bidirectional phase change temperature regulating layer 5 are configured as phase change temperature regulating cotton batting. The dimensions of both layers are 53*53cm, and the dosage of both is 190g / ㎡-220g / ㎡. It should be noted that phase change temperature regulating fiber is a textile material that uses phase change materials (PCMs) for temperature regulation. The core lies in the embedded phase change materials (such as paraffin wax, fatty acids, etc.). These materials undergo physical state changes (solid-liquid conversion) within a specific temperature range. When body temperature rises, the phase change materials melt and absorb heat, preventing overheating of the body surface; when the temperature decreases... Phase change materials release heat upon solidification, maintaining stable body temperature. This material intelligently absorbs and releases heat, acting like a "heat sponge," dynamically balancing body surface temperature and reducing temperature fluctuations. The preferred amount of phase change temperature-regulating cotton filling is set at 200g / ㎡. This means that the comforter core utilizes the property of phase change materials to absorb or release heat during a phase change at a specific temperature, automatically regulating the temperature inside the comforter core. When body temperature rises, the phase change material absorbs and stores heat; when body temperature drops, the phase change material releases the previously stored heat, thus always maintaining the temperature inside the comforter core within a comfortable range for the human body. This effectively solves the technical problem of poor temperature regulation capabilities in traditional comforters, providing users with a comfortable and stable sleep environment.
[0020] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
