Description

Technical Field

[0001] This application relates to the field of healthy home technology, specifically to the field of a freely combinable graphene bamboo charcoal heating module. Background Technology

[0002] Traditional heating and physiotherapy equipment encompasses a variety of forms, from ancient heated brick beds (kang) to modern electric blankets and electric heated brick beds. For example, traditional bluestone kang uses natural stone as the heating panel, releasing heat by heating the stone. While this design can provide a relatively uniform heat distribution and has certain health benefits, its installation conditions are demanding, requiring specific space and structural support. Once installed, it is difficult to move or rearrange, lacking flexibility and making it difficult to apply on a large scale.

[0003] On the other hand, electric blankets are popular as a convenient heating tool due to their portability. However, electric blankets often suffer from uneven heating, although some products use water as a medium to improve heating uniformity. Nevertheless, they also pose serious safety hazards such as overheating and potential fires.

[0004] Therefore, in the field of healthy home furnishings for heating and therapy, there is a demand for products that are easy to install and can improve health benefits. Summary of the Invention

[0005] To address the aforementioned needs, this application proposes a freely combinable graphene bamboo charcoal heating module. The aim is to utilize graphene as the heating element and bamboo charcoal as the heat-conducting panel to form a uniform and efficient heating module. The module is designed with a secure protective shell and an easily combinable power supply module, allowing for free combination and improving its flexibility and adaptability.

[0006] To achieve the above objectives, the present application adopts the following technical solution:

[0007] A freely combinable graphene bamboo charcoal heating module can be freely combined and spliced ​​to expand the heating area. It includes a flat bottom shell, which has a stepped layered structure, divided into an upper mounting part and a lower receiving part.

[0008] It also includes a bamboo charcoal board partially nested and fixed in the mounting part, a graphene heating film attached to the bottom of the bamboo charcoal board, and a flame-retardant layer formed by filling the receiving part with a foaming agent and foaming and curing in situ. The graphene heating film is provided with a power connector, which is located on the outer periphery of the receiving part.

[0009] The tree-branch power cord assembly includes a main power cord and multiple branch power cords corresponding to the power connectors of each heating module. When the heating modules are assembled, the power cord assembly can be routed through the outer periphery of the receiving part.

[0010] Thus, through modular structural design and flexible splicing methods, the heating area can be freely expanded and the spatial layout can be personalized, improving the product's applicability. The heating module adopts a stepped, layered bottom shell structure, with bamboo charcoal boards embedded in the upper mounting section, forming an efficient heat conduction path with the graphene heating film attached to its bottom. At the same time, a composite layer with flame-retardant, heat-insulating, and buffering functions is formed in situ by filling the lower housing section with foaming agent, which not only enhances the safety and stability of the overall structure but also provides support for the tight splicing between modules.

[0011] Meanwhile, by utilizing the stepped bottom shell design and the outer periphery of its lower housing, the power connector and tree-branch power cable assembly are unified, enabling multiple heating modules to achieve independent power supply or collaborative operation in parallel, and facilitating wiring connections, maintenance, and replacement.

[0012] Furthermore, graphene, as a highly efficient heating material, combined with the far-infrared radiation characteristics of the bamboo charcoal panel, not only ensures rapid and uniform heating but also provides excellent health and therapeutic functions. Meanwhile, the flame-retardant layer integrated into the bottom shell effectively enhances the system's fire resistance and service life.

[0013] In some possible implementations, the heating module has standardized geometric dimensions, with its length and width being multiples of A or B, where A and B are basic modular units. When the heating modules are spliced ​​together, they can be linearly expanded along the A or B direction, and multiple heating modules can be spliced ​​together in a rectangular array by combining A×n or B×m, where n and m are positive integers.

[0014] In some possible implementations, A is 300 mm and B is 400 mm.

[0015] In some possible implementations, a metal heat-conducting plate is also included, which is disposed at the bottom of the bamboo charcoal plate and covers the bamboo charcoal plate.

[0016] In some possible implementations, the bottom of the bamboo charcoal board is provided with a plurality of non-through blind holes.

[0017] In some possible implementations, the clearance hole is a cylindrical hole with a diameter of 1 to 5 mm.

[0018] In some possible implementations, the graphene heating film has a mesh-like structure.

[0019] In some possible implementations, a decorative panel may also be provided on top of the bamboo charcoal panel. Attached Figure Description

[0030] The following examples further illustrate the features of this application and other related features in detail, so as to facilitate understanding by those skilled in the art:

[0031] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions in the attached diagrams, while the terms “bottom surface,” “top surface,” “inner,” and “outer” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0032] Furthermore, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this case based on the specific circumstances.

[0033] Please refer to Figure 1 , Figure 2 and Figure 8This application discloses a freely combinable graphene bamboo charcoal heating module, which will be referred to as a heating module in the following description. The heating module has a regular square structure, which can be freely combined and spliced ​​to expand the heating area. Specifically, the heating module has standardized geometric dimensions, with its length and width being multiples of A or B, where A and B are basic modular units. When splicing, the heating module can be linearly expanded along the A or B direction, and multiple heating modules can be spliced ​​in a rectangular array by combining A×n or B×m, where n and m are positive integers.

[0034] For example, if A chooses 300mm and B chooses 400mm, then as optional dimensions, the module sizes that can be made can be various multiples of 300mm and 400mm, such as 600*1200mm, 300*300mm, 400*400mm, 300*400mm, and 400*800mm. Please refer to [reference needed]. Figures 9 to 14 The arrangement of a1 to a9 in the attached diagram is an exemplary example of 2 to 9 heating modules when the present application uses a size specification of 600*1200mm. Of course, sizes such as 750*1500mm and 500*1000mm can also be used.

[0035] Furthermore, in practical applications, the size of the tiles used will be matched with the existing floor tile structure. For example, standard floor tiles of 300*300mm, 600*600mm, and 800*800mm have a square structure, which is actually an A=B structural form. Please refer to [reference needed]. Figures 15 to 16 b1~b4 are exemplary examples of heating modules with a size specification of 600*600mm.

[0036] Because they share the same basic modular unit, their shapes and sizes can be freely combined, such as... Figure 8 In the middle, different combinations are used to form an extended heating module with dimensions of 1000*1500mm. For ease of description, Figure 8 The diagram shows the components in their spread-out state; in actual application, the heating modules will be tightly joined together. The precisely designed graphene bamboo charcoal heating module can be widely used in various scenarios (homes, nurseries, offices, game rooms, nursing homes, kindergartens, medical clinics, health and wellness stores, etc.).

[0037] To achieve the freely combinable heating modules described above, issues related to heating uniformity, safety, and power wiring need to be addressed.

[0038] Please refer to the following for details. Figures 1 to 4This application discloses a freely combinable graphene bamboo charcoal heating module, comprising a flat-lying base shell 1. The base shell 1 has a stepped, layered structure, divided into an upper mounting section 11 and a lower accommodating section 12. The material can be ABS (acrylonitrile-butadiene-styrene copolymer), with PC (polycarbonate) added as needed to improve its impact resistance and heat resistance, making it more suitable for combinable heating modules. The addition ratio can be 5-15%.

[0039] The panel accessible to the user also includes a bamboo charcoal board 2 that can be nested into and fixed to the mounting part 11. The thickness of the bamboo charcoal board 2 can be selected to be relatively thick, ranging from 15 to 30 mm. Bamboo charcoal has a rich microporous and mesoporous structure with a large specific surface area (usually 300-400 m² / g), which can effectively absorb harmful gases such as formaldehyde and benzene, as well as odors and moisture in the air, and promote blood circulation.

[0040] Furthermore, bamboo charcoal has a moisture absorption rate of 10-15%, which allows it to absorb or release moisture according to the ambient humidity, maintaining a humidity balance of ±5%RH. At the same time, it inhibits the growth of bacteria and mold, effectively suppressing Escherichia coli and Staphylococcus aureus.

[0041] Bamboo charcoal materials calcined at 800℃ do not burn when exposed to open flames, and when heated, the surface microcurrent can release 1000-5000 negative oxygen ions / cm³, which helps to improve air quality.

[0042] A decorative panel 21 can be added to the top of the bamboo charcoal board 2. For example, a black walnut wood veneer decorative panel 21 with a thickness of 0.5-2mm can be used according to the home style. This has little impact on the bamboo charcoal board 2 and achieves a good appearance.

[0043] As the heating element, a graphene heating film 3 is attached to the bottom of the bamboo charcoal board 2. Graphene boasts a 95% electrothermal conversion rate and a far-infrared emissivity of up to 89%. Furthermore, a 1mm thick graphene sheet can peel off approximately 3 million graphene particles, resulting in a high specific surface area, theoretically reaching 2630㎡ / g. After 90,000 hours of operation, the surface area decays by ≤1%, ensuring its continued use. The emitted far-infrared rays, with a wavelength of 4-16µm, can penetrate deep into human tissue at room temperature, reaching a depth of 5-7cm to provide heat therapy directly to the cartilage layer. This activates the body's cell nuclei, proteins, and other biomolecules, improving blood circulation, detoxifying, reducing inflammation, and relieving pain.

[0044] Preferably, the graphene heating film 3 has a mesh structure, which can effectively improve the uniformity of current distribution and reduce local thermal resistance. Metal conductive plates 31 are connected to both ends of the graphene heating film 3, and the metal conductive plates 31 are used to achieve electrical connection with the external power connector 32 and to provide current sharing. Specifically, the metal conductive plates 31 can be made of copper.

[0045] Thus, graphene, as a highly efficient heating material, combined with the far-infrared radiation characteristics of bamboo charcoal board 2, not only ensures rapid and uniform heating but also has good health and therapeutic functions.

[0046] Furthermore, a flame-retardant layer 4 is formed in the housing 12 by filling with a foaming agent and then foaming and curing it in situ. The flame-retardant layer 4 integrated inside the bottom shell 1 effectively improves the fire resistance and service life of the heating module.

[0047] At this point, because the bottom shell 1 has a stepped structure design, some bamboo charcoal panels 2 are not covered by the graphene heating film 3, meaning that less heat is distributed around the outer periphery of the bamboo charcoal panels 2, resulting in uneven heat distribution across the entire panel. To address this, this application provides a metal heat-conducting plate 5 covering the bottom of the bamboo charcoal panels 2. The metal heat-conducting plate 5 can be made of aluminum, and its thickness can be selected according to requirements. In this embodiment, a thickness of 2-3 mm can be selected, allowing the heat from the graphene heating film 3 to be evenly distributed to the outer periphery of the bamboo charcoal panels 2 through the metal heat-conducting plate 5. Furthermore, the entire assembly process only requires sequentially attaching the metal heat-conducting plate 5 and the graphene heating film 3 to the bottom of the bamboo charcoal panels 2, then attaching the entire bamboo charcoal panels 2 to the mounting portion 11 of the bottom shell 1, and finally filling the injection port 13 of the receiving portion 12 with foaming agent and sealing the injection port 13 to allow for foaming and molding.

[0048] Thus, through modular structural design and flexible splicing methods, the heating area can be freely expanded and the spatial layout can be personalized, improving the product's applicability. The heating module adopts a stepped layered bottom shell 1 structure, with the bamboo charcoal board 2 embedded in the upper mounting part 11, forming an efficient heat conduction path with the graphene heating film 3 attached to its bottom. At the same time, a flame-retardant layer 4 with flame-retardant, heat-insulating, and buffering functions is formed in situ by filling the lower accommodating part 12 with foaming agent, which not only enhances the safety and stability of the overall structure but also provides support for the tight splicing between modules.

[0049] As for the power supply system, please refer to the following: Figure 5 and Figure 6 The power connector 32 is located on the outer periphery of the accommodating part 12 and can be hidden from a top view. The power cord adopts a tree-branch power cord assembly, including a main power cord and multiple branch power cords corresponding to the power connectors of each heating module. When the heating modules are assembled, the power cord assembly can be routed through the outer periphery of the accommodating part 12.

[0050] Specifically, a cylindrical quick-connect connector can be used, with selectable locking methods including positioning protrusions or limiting grooves on its outer periphery for snap-fit ​​connection and fixation. Alternatively, a rotation locking function can be employed, where electrical connection and mechanical locking are achieved by rotating to a fixed angle after insertion, suitable for the rapid assembly and disassembly requirements of modular splicing systems. The cylindrical shape allows it to move freely within the space created around the assembled receiving portion 12 without obstructing the aesthetic appearance of the assembled structure.

[0051] Furthermore, in order to maintain a stable position, an anti-slip pad 14 is provided at the bottom of the bottom shell 1. It has wear resistance, anti-slip properties, shock absorption, and adaptability to different ground materials. The materials that can be used include rubber, silicone, EVA foam, etc.

[0052] Thus, by utilizing the stepped base shell 1 design, and using the outer periphery of its lower accommodating section 12 to unify the power connector 32 and the tree-branch power cord assembly, multiple heating modules can be connected in parallel to achieve independent power supply or collaborative operation, and it is also convenient for wiring connections, maintenance, and replacement. In application, it can be connected to the Mi Home smart control system to realize remote control, timed start / stop, frequency conversion energy saving, power consumption monitoring, real-time current monitoring, and other functions.

[0053] Please refer to Figure 7 Multiple non-through blind holes 22 can be provided at the bottom of the bamboo charcoal board 2. Preferably, the blind holes 22 are cylindrical holes with a diameter of 1~5mm, which can be drilled, CNC machined or laser drilled, which is convenient for mass production. More specifically, the hole spacing can be 10-50mm, and the hole depth can not exceed 3 / 4 of the total thickness of the bamboo charcoal board 2, and they can be arranged in an array, staggered, or densely arranged along the edge.

[0054] Thus, the bamboo charcoal board 2 is equipped with multiple non-penetrating blind holes 22, which effectively solves the structural failure problems such as thermal expansion stress concentration, local deformation, and even cracking that easily occur in bamboo charcoal materials during long-term heating.

[0055] Furthermore, the well-distributed open areas optimize and control the heat transfer path. Without compromising the overall strength of the bamboo charcoal board 2, it significantly improves the uniformity of the heat field distribution of the heating module during operation, resulting in a more stable and comfortable temperature on the user's contact surface, thus enhancing product safety and user experience.

[0056] As stated above, this case protects a freely combinable graphene bamboo charcoal heating module, and all technical solutions that are the same as or similar to this case should be considered to fall within the protection scope of this case.
