[0061] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0062] The present application provides a heating component 100, which can be applied to seats 200, sofas, mattresses, etc. The heating component 100 of the present application is achieved by arranging temperature-regulating particles 30 in the filling layer 12 and opening an air flow channel 40 on the filling layer 12. When the heater 20 arranged in or on the filling layer 12 is heated, the heat is absorbed by the temperature-regulating particles 30. In the process of the air flow on the lower side of the filling layer 12 passing through the filling layer 12 via the air flow channel 40, the air flow will exchange heat with the temperature-regulating particles 30. Since the temperature-regulating particles 30 have a temperature regulation function, the temperature of the air flow after heat exchange with the temperature-regulating particles 30 is relatively stable and will not fluctuate greatly, thereby improving the stability of the heat conduction temperature and enhancing comfort. It also at least partially solves the technical problem of unstable heat conduction temperature felt by users in the prior art, resulting in low comfort.

[0063] like Figure 1 As shown, Figure 11 is a structural diagram of a filling layer 12 provided in the exemplary embodiment 1 of the present application. The filling layer 12 can be sponge, foam material, fiber material, etc. The filling layer 12 is used to provide support and comfort.

[0064] The filling layer 12 is provided with temperature-regulating particles 30. These particles 30 are particles with a temperature-regulating function, such as phase-change material particles. The temperature-regulating particles 30 primarily function based on the properties of phase-change materials. Phase-change materials undergo a physical phase change, such as from solid to liquid or vice versa, when the temperature reaches a specific value. During this process, they absorb or release a large amount of heat, thereby regulating the temperature. For example, when the ambient temperature rises, the temperature-regulating particles 30 absorb heat and undergo a phase change, storing the heat and preventing the temperature from rising too high. When the ambient temperature drops, the temperature-regulating particles 30 release heat, slowing the temperature drop and achieving a certain degree of temperature regulation. Of course, the temperature-regulating particles 30 can also be particles with special physical or chemical properties, such as ceramic particles with excellent thermal insulation properties or metal oxide particles that absorb and reflect heat. These particles influence temperature characteristics through different mechanisms, such as reducing heat transfer or reflecting thermal radiation, thereby regulating the temperature to a certain extent.

[0065] The filling layer 12 is provided with an airflow channel 40, through which air flows through the filling layer 12. Specifically, the main function of the airflow channel 40 is to facilitate the circulation of air. The airflow channel 40 may be through the thickness of the filling layer 12, or it may not be through. For example, a blind channel may be provided on the upper or lower surface of the filling layer 12 as the airflow channel 40, or the airflow channel 40 may be provided inside the filling layer 12.

[0066] In this embodiment, the airflow channel 40 penetrates the filling layer 12 along the thickness direction of the filling layer 12. In other words, the airflow channel 40 runs through the thickness direction of the filling layer 12, allowing airflow on one side of the filling layer 12 to flow smoothly to the other side through the airflow channel 40, for example, from the bottom to the top, or from the top to the bottom. The structure of the airflow channel 40 will be described in detail later.

[0067] The present application provides temperature-regulating particles 30 in the filling layer 12 and opens an air flow channel 40 that penetrates the filling layer 12. When the heater 20 heats, the heat will be absorbed by the temperature-regulating particles 30. In the process of the air flow on the lower side of the filling layer 12 passing through the filling layer 12 via the air flow channel 40, the air flow will exchange heat with the temperature-regulating particles 30. Since the temperature-regulating particles 30 have a temperature regulation function, the temperature of the air flow after heat exchange with the temperature-regulating particles 30 is relatively stable and will not fluctuate greatly, thereby improving the stability of the heat conduction temperature and enhancing comfort. It also at least partially solves the technical problem of unstable heat conduction temperature felt by users in the prior art, resulting in low comfort.

[0068] The structure of the air flow channel 40 is described in detail below.

[0069] In some embodiments, as Figure 2 As shown, at least a portion of the airflow channel 40 extends in a non-linear direction. That is, the airflow channel 40 does not pass straight through the filling layer 12, but is at least partially non-linear and curved. At least a portion of the airflow channel 40 bends in the thickness direction of the filling layer 12. By making at least a portion of the airflow channel 40 extend in a non-linear direction, the length of the airflow channel 40 is increased, thereby increasing the time for the airflow to pass through the filling layer 12. Correspondingly, the heat exchange time between the airflow and the temperature-regulating particles 30 is increased, thereby improving heat exchange efficiency.

[0070] Specifically, the specific structures of the airflow channel 40 include at least the following types.

[0071] The first one:

[0072] like Figure 3 As shown, the airflow channel 40 includes a first channel section 41 and a second channel section 42. The second channel section 42 is connected to the first channel section 41. The first channel section 41 and the second channel section 42 extend in different directions. Because the first channel section 41 and the second channel section 42 extend in different directions, the airflow must turn after passing through the second channel section 42 before entering the first channel section 41. This turn reduces the flow velocity of the airflow, increasing the time it takes to pass through the filling layer 12. Correspondingly, it increases the heat exchange time between the airflow and the temperature-regulating particles 30, allowing for more complete heat exchange between the second channel section 42 and the first channel section 41, thereby improving heat exchange efficiency.

[0073] Specifically, the first channel section 41 and the second channel section 42 are both straight channels, and the first channel section 41 and the second channel section 42 form a substantially V-shaped airflow channel 40 .

[0074] The second type:

[0075] like Figure 3As shown, the airflow channel 40 includes a first channel section 41, a second channel section 42, and a third channel section 43. The third channel section 43 connects the first channel section 41 and the second channel section 42. At least the extension direction of the third channel section 43 is different from that of the first channel section 41, and at least the extension direction of the third channel section 43 is different from that of the second channel section 42.

[0076] Since the extension direction of the third channel section 43 is different from the extension directions of the first channel section 41 and the second channel section 42, the airflow needs to turn after passing through the second channel section 42 to enter the third channel section 43, and then needs to turn from the third channel section 43 to enter the first channel section 41. Through two turns, the extension direction of the third channel section 43 is set to be different from the extension directions of the first channel section 41 and the second channel section 42, so as to reduce the flow speed of the airflow and increase the time for the airflow to pass through the filling layer 12. Correspondingly, the heat exchange time between the airflow and the temperature-regulating particles 30 is increased, thereby improving the heat exchange efficiency.

[0077] It is understandable that the first channel section 41 and the second channel section 42 may extend in the same or different directions. The third channel section 43 extends in a direction different from the thickness direction of the filling layer 12. By setting the extension direction of the third channel section 43 to be different from the thickness direction of the filling layer 12, the length of the airflow channel 40 is increased.

[0078] In this embodiment, the first channel segment 41 and the second channel segment 42 extend in the same direction, both along the thickness direction of the filling layer 12, while the third channel segment 43 extends in a direction perpendicular to the thickness direction of the filling layer 12. Of course, in other embodiments, the extending directions of the first channel segment 41, the second channel segment 42, and the third channel segment 43 are not limited to the above, as long as the extending direction of the middle segment is set to be different from the extending directions of the two end segments, and the specific setting can be made as needed.

[0079] The third type:

[0080] like Figure 4 As shown, the airflow channel 40 includes a first channel section 41, a second channel section 42, and a third channel section 43. The third channel section 43 connects the first channel section 41 and the second channel section 42. The extending direction of the first channel section 41 is different from the thickness direction of the filling layer 12, and the extending direction of the second channel section 42 is different from the thickness direction of the filling layer 12.

[0081] By setting the extension direction of the first channel section 41 and the second channel section 42 to be different from the thickness direction of the filling layer 12, the airflow enters the third channel section 43 after passing through the second channel section 42, and then enters the first channel section 41 from the third channel section 43. Since the extension direction of the first channel section 41 and the second channel section 42 is different from the thickness direction of the filling layer 12, the overall length of the airflow channel 40 can be increased, and the time for the airflow to pass through the filling layer 12 can be increased. Correspondingly, the heat exchange time between the airflow and the temperature-regulating particles 30 is increased, thereby improving the heat exchange efficiency.

[0082] In some embodiments, the cross-sectional area of ​​the third channel section 43 is greater than the cross-sectional area of ​​the first channel section 41, and / or the cross-sectional area of ​​the third channel section 43 is greater than the cross-sectional area of ​​the second channel section 42. In other words, the cross-sectional area of ​​the third channel section 43 may be greater than only the cross-sectional area of ​​the first channel section 41 or the cross-sectional area of ​​the second channel section 42, or may be greater than both the cross-sectional area of ​​the first channel section 41 and / or the cross-sectional area of ​​the second channel section 42. By setting the cross-sectional area of ​​the third channel section 43 to be greater than the cross-sectional area of ​​the first channel section 41 and / or the second channel section 42, the airflow can be disturbed when it enters the third channel section 43 after passing through the second channel section 42, reducing the airflow velocity and further increasing the time it takes for the airflow to pass through the filling layer 12. Correspondingly, the heat exchange time between the airflow and the temperature-regulating particles 30 is increased, thereby improving heat exchange efficiency.

[0083] The temperature regulating particles 30 are introduced in detail below. The following features of the temperature regulating particles 30 can be combined with the structure of any of the aforementioned air flow channels 40 and will not be introduced in detail here.

[0084] In some embodiments, the temperature regulating particles 30 include phase change microcapsules 31 .

[0085] Phase-change microcapsules 31 are particles with a core-shell structure, encapsulating a phase-change material (core material) within a tiny capsule using microencapsulation technology. Phase-change microcapsules 31 typically consist of a shell and a core. The shell forms a closed cavity, and the core is filled with phase-change material.

[0086] To meet different temperature control needs and application environment requirements, the phase change microcapsules 31 can use different types of phase change materials as the capsule core to achieve different phase change temperature ranges. For example, paraffin phase change materials with different chain lengths can be selected for temperature control. For example, if a capsule core with a phase change point of 20 degrees Celsius is required, paraffin with a carbon chain length of 16-18 can be selected; if a capsule core with a phase change point of 28 degrees Celsius is required, paraffin with a carbon chain length of 20-22 can be selected; if a capsule core with a phase change point of 36 degrees Celsius is required, paraffin with a carbon chain length of 24-26 can be selected; and if a capsule core with a phase change point of 42 degrees Celsius is required, paraffin with a carbon chain length of 28 can be selected.

[0087] Of course, in addition to paraffin, there are other phase change materials that can be used for temperature control, such as molten salt, hydrated salt, low-melting-point metals, etc.

[0088] In some embodiments, the phase change temperature of the phase change microcapsule 31 is set to 30-45 degrees Celsius in combination with the heating temperature of the heater 20. The phase change temperature refers to the thermodynamic transition temperature of the phase change material in the phase change microcapsule 31 during solid-liquid, liquid-solid or other phase transitions. At this temperature point, the phase change microcapsule 31 absorbs or releases latent heat to achieve temperature regulation, so that the surface temperature of the temperature control area tends to a relatively stable state. By setting the phase change temperature of the phase change microcapsule 31 to 30-45 degrees Celsius, the heating temperature matching requirements of the heater 20 can be better met, thereby improving user comfort.

[0089] like Figure 6 As shown, in some embodiments, the temperature-regulating particles 30 include at least two phase-change microcapsules 31 , namely, first phase-change microcapsules 311 and second phase-change microcapsules 312 . Different types of phase-change microcapsules 31 have different phase-change temperatures.

[0090] It can be understood that the "types" of phase change microcapsules 31 are two or more, and the number of individuals of each phase change microcapsule 31 can be multiple. Since the phase change temperatures of various types of phase change microcapsules 31 are different, thermal regulation can be achieved in multiple temperature ranges during use. For example, when the temperature regulating particles 30 contain two types of phase change microcapsules 31, the temperature is maintained stable near the two phase change temperature points; when three types of phase change microcapsules 31 are included, the temperature regulation function can be provided near the three phase change temperature points, thereby helping to achieve a wider range and more precise temperature control. It should be noted that "the temperature is maintained near the phase change temperature" means that the temperature is relatively stable in a certain set phase change temperature range within a certain time scale, and is not constant.

[0091] Each phase-change microcapsule 31 has a different phase-change temperature. This design allows each phase-change microcapsule 31 to enter a different phase-change stage at different ambient temperatures, thereby achieving multi-temperature zone control. Specifically, as the ambient temperature changes, the phase-change microcapsules 31 with different phase-change temperatures sequentially absorb or release heat, maintaining relatively stable temperatures across multiple temperature zones. This enables more precise temperature control in practical applications and improves the overall user experience.

[0092] In some embodiments, as Figure 5As shown, the temperature-regulating particles 30 include two phase-change microcapsules 31, namely, first phase-change microcapsules 311 and second phase-change microcapsules 312. For example, the first phase-change microcapsules 311 can have a lower phase-change temperature, while the second phase-change microcapsules 312 can have a higher phase-change temperature, suitable for different temperature sensations. By setting the first phase-change microcapsules 311 and second phase-change microcapsules 312 to have different phase-change temperatures, the system can be adapted to different temperature environments or for users with different needs.

[0093] Specifically, for example, the phase change temperature of the first phase change microcapsule 311 phase change microcapsule 31 can be set to 33-39 degrees Celsius, such as 33, 34, 35, 36, 37, 38, and 39 degrees Celsius. In addition, the phase change temperature of the second phase change microcapsule 312 phase change microcapsule 31 can be set to 40-44 degrees Celsius, such as 40, 41, 42, 43, and 44 degrees Celsius. For example, at the beginning of winter, the user may need low-speed hot air heating, turn on the low speed of the heater 20, and the heater 20 continues to heat. The first phase change microcapsule 311 phase change microcapsule 31 and the second phase change microcapsule 312 phase change microcapsule 31 absorb heat and continue to absorb heat. The airflow through the airflow channel 40 exchanges heat with the first phase change microcapsule 311 phase change microcapsule 31 and the second phase change microcapsule 312 phase change microcapsule 31.

[0094] For example, at the beginning of winter, the user can turn on the low-speed heating of the heater 20. The first phase change microcapsule 311 can absorb heat from the heater 20 and store the heat through the phase change process of the first phase change microcapsule 311. This effectively suppresses the temperature increase caused by the high heating temperature or long heating time of the heater 20, and controls the temperature at 33-39 degrees Celsius. The airflow through the airflow channel 40 exchanges heat with the first phase change microcapsule 311. The temperature of the airflow is also relatively more stable, making the user feel more comfortable and improving the overall comfort of use.

[0095] For example, in the cold winter, the user can turn on the high-end heating of the heater 20. The first phase change microcapsule 311 phase change microcapsule 31 and the second phase change microcapsule 312 phase change microcapsule 31 can absorb heat from the heater 20 and store the heat through the phase change process of the second phase change microcapsule 312 phase change microcapsule 31, thereby effectively suppressing the temperature increase caused by the high heating temperature or long heating time of the heater 20, and controlling the temperature at 40-44 degrees Celsius. The airflow through the airflow channel 40 exchanges heat with the second phase change microcapsule 312 phase change microcapsule 31, and the temperature of the airflow is also relatively more stable, making the user feel more comfortable and improving the overall comfort of use.

[0096] In some embodiments, the phase transition temperature of the first phase-change microcapsule 311 is specifically set to 36 degrees Celsius; and / or the phase transition temperature of the second phase-change microcapsule 312 is specifically set to 42 degrees Celsius. In other embodiments, the phase transition temperatures of the first phase-change microcapsule 311 and the second phase-change microcapsule 312 can also be set to other temperatures, which are selected according to specific needs and are not limited here.

[0097] In some embodiments, in order to improve the heat exchange efficiency between the heater 20 and the phase-change microcapsules 31 , the thermal conductivity of the shell of the phase-change microcapsules 31 is set to be greater than or equal to 0.5 W / (mK).

[0098] Watts per meter per degree (W / (m·K)) is the unit of thermal conductivity of a material. It's used to quantify how efficiently a material conducts heat. A higher value indicates a material's greater heat transfer capability.

[0099] The thermal conductivity of ordinary phase change microcapsules 31 is 0.1-0.2W / (mK), which is not high. Therefore, by setting the shell of the phase change microcapsule 31 with a thermal conductivity greater than or equal to 0.5W / (mK), the heat exchange efficiency between the heater 20 and the phase change microcapsule 31 is improved. After the heater 20 is heated, the phase change microcapsule 31 can exchange heat more quickly with the phase change microcapsule 31, and the phase change microcapsule 31 can also exchange heat with the airflow in the airflow channel 40 more quickly after absorbing heat, thereby improving the heating effect of the heating component 100 and enhancing the overall comfort.

[0100] In some embodiments, to improve the heat exchange efficiency between the heater 20 and the phase-change microcapsules 31, the thermal conductivity of the shell of the phase-change microcapsules 31 is set to be greater than or equal to 0.7 W / (mK). By using phase-change microcapsules 31 with higher thermal conductivity, the heat exchange efficiency between the heater 20 and the phase-change microcapsules 31 is further improved, further enhancing the heating effect of the heating assembly 100 and improving overall comfort.

[0101] In some embodiments, the shell of the phase-change microcapsule 31 contains at least one of carbon nanotubes, graphene oxide, and cellulose nanocrystal emulsion combined with polypyrrole.

[0102] Carbon nanotubes (CNTs) are a unique one-dimensional quantum material composed primarily of several to dozens of layers of coaxial circular tubes of carbon atoms arranged in a hexagonal pattern. CNTs have radial dimensions on the order of nanometers and axial dimensions on the order of micrometers, and are typically sealed at both ends.

[0103] Graphene oxide is an oxidized derivative of graphene or functionalized graphene, and is a complex compound generated by an oxidation reaction of graphene.

[0104] Cellulose nanocrystals (CNCs) are nanoscale rod-shaped crystalline particles extracted chemically or mechanically from natural cellulose (such as plant fibers, wood, cotton, algae, etc.). Polypyrrole is a typical conductive polymer (conjugated polymer) formed from pyrrole monomers through oxidative polymerization or electrochemical polymerization.

[0105] Specifically, conventional phase-change microcapsules 31 are modified by adding at least one of carbon nanotubes, graphene oxide, and cellulose nanocrystal emulsion combined with polypyrrole to the shells of phase-change microcapsules 31. Experimental data shows that adding carbon nanotubes and / or graphene oxide to the shells of conventional phase-change microcapsules 31 with a thermal conductivity of 0.12 W / (mK) can increase the thermal conductivity to 0.75 W / (mK). Furthermore, adding cellulose nanocrystal emulsion combined with polypyrrole to the shells of conventional phase-change microcapsules 31 with a thermal conductivity of 0.1 W / (mK) can increase the thermal conductivity to 0.75 W / (mK).

[0106] At least one of carbon nanotubes, graphene oxide, and cellulose nanocrystal emulsion combined with polypyrrole is added to ordinary phase change microcapsules 31 to improve the thermal conductivity of the phase change microcapsules 31. By adopting phase change microcapsules 31 with higher thermal conductivity, the heat exchange efficiency between the heater 20 and the phase change microcapsules 31 is further improved, the heating effect of the heating component 100 is further improved, and the overall comfort is enhanced.

[0107] The present application also provides a heating assembly 100 . The heating assembly 100 can be applied to a seat 200 , a sofa, a mattress, etc. The heating assembly 100 includes a body 10 and a heater 20 . The heater 20 is used to heat the body 10 .

[0108] Specifically, the body 10 includes the aforementioned filling layer 12 .

[0109] The heater 20 may be a resistance heater 20, a semiconductor heater 20, or an electromagnetic heater 20. In this embodiment, the heater 20 is described as a resistance heater 20.

[0110] The heater 20 can be set in two ways.

[0111] Method 1:

[0112] like Figure 6 As shown, the heater 20 is stacked with the filling layer 12 , for example, it is arranged on the upper surface or the lower surface of the filling layer 12 , and the specific arrangement can be determined as needed.

[0113] Because the filling layer 12 is provided with temperature-regulating particles 30, when the heater 20 heats, the heat is absorbed by the temperature-regulating particles 30. For example, the temperature-regulating particles 30 are phase-change material particles. When the heater 20 heats, the heat is absorbed by the temperature-regulating particles 30, i.e., the phase-change material particles, within the filling layer 12. Due to the properties of the phase-change material, the phase-change material particles continuously absorb heat emitted by the heater 20. When the temperature reaches a specific value, a physical state change occurs, such as from solid to liquid. During this process, the phase-change material particles absorb a large amount of heat, but the temperature does not continue to rise, achieving a stable temperature.

[0114] At the same time, when the airflow on the lower side of the filling layer 12 passes through the filling layer 12 through the airflow channel 40, the airflow will exchange heat with the temperature regulating particles 30, i.e., the phase change material particles. The phase change material particles will release a large amount of heat, and the airflow temperature will increase. Since the temperature will remain stable when the phase change temperature of the phase change material particles is reached, the temperature of the airflow after heat exchange with the phase change material is also relatively stable and will not fluctuate greatly, thereby improving the stability of the heat conduction temperature and enhancing comfort. It at least partially solves the technical problem of unstable heat conduction temperature felt by users in the prior art, resulting in low comfort.

[0115] Method 2:

[0116] like Figure 7 As shown, the heater 20 is disposed within the filling layer 12 .

[0117] The principle is similar to that of method 1. Because the filling layer 12 is provided with temperature-regulating particles 30, when the heater 20 heats, the heat is absorbed by the temperature-regulating particles 30. As the airflow from the lower side of the filling layer 12 passes through the filling layer 12 via the airflow channel 40, it exchanges heat with the temperature-regulating particles 30. Since the temperature-regulating particles 30 have a temperature-regulating function, the temperature of the airflow after the heat exchange with the temperature-regulating particles 30 is relatively stable and does not fluctuate significantly. This improves the stability of the heat transfer temperature and enhances comfort. It also at least partially solves the technical problem of unstable heat transfer temperature and low comfort experienced by users in the prior art.

[0118] The heating component 100 of the present application is achieved by providing a filling layer 12, and stacking a heater 20 on the filling layer 12 or providing the heater 20 in the filling layer 12. When the heater 20 heats, the heat is absorbed by the temperature-regulating particles 30. During the process of the airflow on the lower side of the filling layer 12 passing through the filling layer 12 via the airflow channel 40, the airflow will exchange heat with the temperature-regulating particles 30. Since the temperature-regulating particles 30 have a temperature regulating function, the temperature of the airflow after heat exchange with the temperature-regulating particles 30 is relatively stable and will not fluctuate greatly, thereby improving the stability of the heat conduction temperature and enhancing comfort. It also at least partially solves the technical problem of unstable heat conduction temperature felt by users in the prior art, resulting in low comfort.

[0119] The following describes the layout of the heater 20 and the temperature-regulating particles 30 . This layout is applicable to any of the aforementioned arrangements of the airflow channel 40 and the temperature-regulating particles 30 .

[0120] First, the structure of the main body 10 is introduced. In this embodiment, Figure 8 As shown, the body 10 includes a cover 11 in addition to a filling layer 12. The filling layer 12 includes a buffer layer 121 and a support layer 122. The buffer layer 121 is located between the cover 11 and the support layer 122. If the cover 11 is located at the top, the buffer layer 121 is located in the middle, and the support layer 122 is located at the bottom.

[0121] The following describes the setting method.

[0122] First way:

[0123] In some embodiments, the heater 20 is located between the buffer layer 121 and the support layer 122 , and the buffer layer 121 and the support layer 122 are provided with temperature-regulating particles 30 .

[0124] Because the buffer layer 121 and the support layer 122 are provided with temperature-regulating particles 30, when the heater 20 is heating, heat is absorbed by the buffer layer 121 located above the heater 20 and the temperature-regulating particles 30 located within the support layer 122 located below the heater 20. As the airflow from the underside of the filling layer 12 passes through the filling layer 12 via the airflow channel 40, it exchanges heat with the temperature-regulating particles 30. Since the temperature-regulating particles 30 have a temperature-regulating function, the temperature of the airflow after heat exchange with the temperature-regulating particles 30 is stable and does not fluctuate significantly. This improves the stability of the heat transfer temperature and enhances comfort. This also at least partially resolves the technical problem in the prior art of unstable heat transfer temperature and resulting low comfort experienced by users.

[0125] Second way:

[0126] In some embodiments, as Figure 9 As shown, the heater 20 is located in the supporting layer 122 , and at least the supporting layer 122 of the buffer layer 121 and the supporting layer 122 is provided with temperature regulating particles 30 .

[0127] exist Figure 8 The figure shows the support layer 122 being provided with temperature-regulating particles 30. When the heater 20 is heating, the heat is absorbed by the temperature-regulating particles 30 within the support layer 122. As the airflow from the underside of the filling layer 12 passes through the filling layer 12 via the airflow channel 40, it exchanges heat with the temperature-regulating particles 30. Because the temperature-regulating particles 30 have a temperature-regulating function, the temperature of the airflow after heat exchange with the temperature-regulating particles 30 is stable and does not fluctuate significantly. This improves the stability of the heat transfer temperature and enhances comfort. This also at least partially resolves the technical problem of unstable heat transfer temperature and low comfort experienced by users in the prior art.

[0128] It is understandable that the buffer layer 121 may also be provided with temperature-regulating particles 30 . When the heater 20 is heating, the heat will be absorbed by the temperature-regulating particles 30 in the support layer 122 and the buffer layer 121 at the same time.

[0129] The third way:

[0130] In some embodiments, as Figure 10 As shown, the heater 20 is arranged between the buffer layer 121 and the face cover 11 , and at least the buffer layer 121 of the buffer layer 121 and the support layer 122 is provided with temperature regulating particles 30 .

[0131] exist Figure 9 The figure shows the buffer layer 121 being provided with temperature-regulating particles 30. When the heater 20 is heating, the heat is absorbed by the temperature-regulating particles 30 within the buffer layer 121. As the airflow from the underside of the filling layer 12 passes through the filling layer 12 via the airflow channel 40, it exchanges heat with the temperature-regulating particles 30. Because the temperature-regulating particles 30 have a temperature-regulating function, the temperature of the airflow after heat exchange with the temperature-regulating particles 30 is stable and does not fluctuate significantly. This improves the stability of the heat transfer temperature and enhances comfort. This also at least partially resolves the technical problem of unstable heat transfer temperature and low comfort experienced by users in the prior art.

[0132] It is understandable that the support layer 122 may also be provided with temperature-regulating particles 30 . When the heater 20 is heating, the heat will be absorbed by the temperature-regulating particles 30 in the support layer 122 and the buffer layer 121 at the same time.

[0133] The position of the airflow accelerator 50 is described below.

[0134] In some embodiments, as Figure 11 As shown, in order to increase the speed of the airflow so that heat can be transferred faster when the heater 20 is turned on, the heating component 100 also includes an airflow accelerator 50. The airflow accelerator 50 is stacked with the filling layer 12, such as being arranged on the upper surface of the filling layer 12 or on the lower surface of the filling layer 12. In this embodiment, the airflow accelerator 50 is arranged on the lower surface of the filling layer 12, and the airflow is accelerated by the airflow accelerator 50 and then passes through the airflow channel 40.

[0135] By providing the airflow accelerator 50 , the speed of the airflow can be increased, and when the heater 20 is turned on, the heat can be transferred to the user more quickly, thereby improving the user's comfort.

[0136] Specifically, in this embodiment, the airflow accelerator 50 is a fan. In other embodiments, the airflow accelerator 50 can be other devices that can accelerate the flow of air, such as a blower.

[0137] The heating component 100 of the present application is achieved by providing a filling layer 12, and stacking a heater 20 on the filling layer 12 or providing the heater 20 in the filling layer 12. When the heater 20 heats, the heat is absorbed by the temperature-regulating particles 30. During the process of the airflow on the lower side of the filling layer 12 passing through the filling layer 12 via the airflow channel 40, the airflow will exchange heat with the temperature-regulating particles 30. Since the temperature-regulating particles 30 have a temperature regulating function, the temperature of the airflow after heat exchange with the temperature-regulating particles 30 is relatively stable and will not fluctuate greatly, thereby improving the stability of the heat conduction temperature and enhancing comfort. It also at least partially solves the technical problem of unstable heat conduction temperature felt by users in the prior art, resulting in low comfort.

[0138] The present application also provides a seat 200, such as Figure 12 As shown, the seat 200 includes the aforementioned filling layer 12 or heating assembly 100. The seat 200 has all the beneficial effects of the aforementioned filling layer 12 or heating assembly 100, which will not be described in detail.

[0139] By providing a heating component 100 or a filling layer 12, the seat 200 can make the heating temperature more stable and avoid large fluctuations, thereby improving the stability of the heat conduction temperature and enhancing comfort. It also at least partially solves the technical problem of unstable heat conduction temperature felt by users in the prior art, resulting in low comfort.

[0140] In some embodiments, the chair 200 further includes a seat body 210, on which a heating assembly 100 is disposed. The provision of the heating assembly 100 on the seat body 210 can enhance user comfort. Whether the backrest 220 needs to be provided with the heating assembly 100 can be determined as needed.

[0141] In some embodiments, the chair 200 further includes a backrest 220 connected to the seat body 210, and a heating assembly 100 is provided on the backrest 220. In other words, it is preferred that the backrest 220 also be provided with a heating assembly 100, so as to further improve the user's comfort.

[0142] The present application also provides a vehicle, which includes the aforementioned filling layer 12 or seat 200 or the aforementioned heating component 100. The vehicle has all the beneficial effects of the aforementioned filling layer 12 or seat 200 or heating component 100, which will not be repeated here.

[0143] By providing a filling layer 12 or a seat 200 or a heating component 100, the vehicle can make the heating temperature more stable and avoid large fluctuations, thereby improving the stability of the heat conduction temperature and enhancing comfort. It also at least partially solves the technical problem of unstable heat conduction temperature felt by users in the prior art, resulting in low comfort.
