[0023] A heating plate is a food container with heating and heat preservation functions, which can keep food at a suitable temperature, thereby maintaining the quality and taste of the food.

[0024] However, existing heating plates lack voice control, positioning functionality, and other related dietary management features. Furthermore, the heating elements in existing heating plates generate significant electromagnetic radiation during operation, interfering with nearby electronic modules. This leads to problems such as decreased positioning accuracy, inaccurate voice recognition, and signal transmission interruptions, severely impacting the reliability and usability of the device. Therefore, integrating dietary management functions despite the presence of electromagnetic interference from the heating element is an important research direction.

[0025] In order to at least solve the problem of integrating diet management functions in the presence of electromagnetic interference in the heating element, embodiments of this application propose a heating plate 100 that can reduce the electromagnetic interference of the heating element 30 to the functional components 40, so that the heating plate can integrate diet management functions in the presence of electromagnetic interference.

[0026] The heating plate 100 of this application embodiment is described below with reference to the accompanying drawings.

[0027] Combination Figure 1 , Figure 2 and Figure 3 As shown, this application proposes a heating plate 100, including: a mounting base 10, a plate body 20, a heating element 30, and a functional component 40. The mounting base 10 defines a shielding cavity 11 and a mounting cavity 12, the shielding cavity 11 being used to shield interference signals. The plate body 20 is detachably mounted to the mounting base 10. The heating element 30 is disposed within the shielding cavity 11 and is used to heat the plate body 20. The functional component 40 includes a positioning module 41, a voice module 42, and a signal transmission module 43, all of which are disposed within the mounting cavity 12.

[0028] The shielding cavity 11 is used to shield interference signals. As one implementation, the mounting base 10 can be a one-piece molded metal or plastic housing, with internal partitions or wall structures dividing the internal space into the shielding cavity 11 and the mounting cavity 12. The inner wall of the shielding cavity 11 can be coated with a conductive material, such as conductive paint or a metal plating, to enhance the reflection and absorption of electromagnetic waves, thereby suppressing electromagnetic interference. The shielding cavity 11 can completely shield interference signals, or it can shield partial signals while the functional component 40 is functioning normally.

[0029] The heating element 30 is disposed within the shielding cavity 11 and is used to heat the disk 20. As one implementation, the heating element 30 can be a resistance wire heater, where current flows through the resistance wire to generate heat, which is then transferred to the disk 20 via conduction or radiation. The resistance wire heater can be fixed to the bottom or side wall of the shielding cavity 11, maintaining a distance from or in direct contact with the bottom of the disk 20. Alternatively, the heating element 30 can be a positive temperature coefficient (PTC) heating element, which has self-limiting temperature characteristics and transfers heat to the disk 20 through contact with the bottom or through a heat transfer medium, ensuring the stability and safety of the heating process. Yet another implementation, the heating element 30 can be an electromagnetic induction coil, which generates an alternating magnetic field to induce eddy currents at the bottom of the disk 20, thus generating heat.

[0030] Functional component 40 includes a positioning module 41, a voice module 42, and a signal transmission module 43, all of which are housed within the mounting cavity 12. In one implementation, the positioning module 41 can employ a Global Positioning System (GPS) module to obtain location information by receiving satellite signals; the voice module 42 can include a microphone and speaker for user voice input and system voice output; and the signal transmission module 43 can employ a Bluetooth or Wi-Fi module for short-range or local area network data communication with other smart devices. Alternatively, the positioning module 41 can employ a cellular network-based location services (LBS) module to obtain location information via a mobile communication network; the voice module 42 can integrate a voice recognition chip and a voice synthesis chip to enable voice interaction; and the signal transmission module 43 can employ a LoRa module for data transmission in short-range scenarios. The positioning module 41, voice module 42 and signal transmission module 43 can be installed independently in different positions within the mounting cavity 12 and electrically connected by wires. Alternatively, the positioning module 41, voice module 42 and signal transmission module 43 can be integrated into one unit and fixed on the support structure within the mounting cavity 12.

[0031] The heating plate 100 of this application embodiment defines a shielding cavity 11 and a mounting cavity 12 within the mounting base 10. The heating element 30 is placed in the shielding cavity 11, and the positioning module 41, the voice module 42, and the signal transmission module 43 are disposed in the mounting cavity 12. When the heating element 30 is working, the shielding cavity 11 can shield the electromagnetic interference generated by the heating element 30, thereby reducing the interference to the positioning module 41, the voice module 42, and the signal transmission module 43, enabling the heating plate 100 to integrate diet management functions in the presence of electromagnetic interference.

[0032] As examples, the heating plate 100 of this embodiment can be applied in the field of medical care. In hospitals or rehabilitation institutions, the voice module 42 can record and play dietary orders or patient needs, the positioning module 41 and the signal sending module 43 can locate the position of the heating plate 100, thereby avoiding confusion between the heating plates 100. The positioning module 41 and the signal sending module 43 can also push the meal collection status to medical staff according to the location, thereby ensuring that patients eat on time.

[0033] As other examples, the heating plate 100 of this embodiment can be used in daily life. After one or more family members prepare a meal, they place the food on the heating plate 100. The voice module 42 can record and play messages. The positioning module 41 and the signal sending module 43 can locate the position of the heating plate 100 and can be linked to a mobile app to push the food retrieval status of the heating plate 100 according to the location.

[0034] It should be noted that the user information and data involved in this application are all information and data that have been fully understood and authorized by the user, and the collection, use and processing of the relevant data must comply with the relevant laws, regulations and standards of the relevant countries and regions.

[0035] Combination Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 9 As shown, in some embodiments, the mounting base 10 includes a base body 13, a panel 14, and a shielding plate 15. The panel 14 abuts against the disk body 20, and the shielding plate 15 is located between the shielding cavity 11 and the mounting cavity 12. The panel 14, the shielding plate 15, and the base body 13 define the shielding cavity 11, and the shielding plate 15 and the base body 13 define the mounting cavity 12.

[0036] The base 13, serving as the fundamental support structure of the entire heating plate 100, can be made using various materials and molding processes. For example, the base 13 can be made of engineering plastic through injection molding, or of metal through stamping, welding, or other processes, to provide stable structural support and good durability. The panel 14 abuts against the plate 20, and its main function is to achieve effective heat transfer. The panel 14 can be made of a metal material with excellent thermal conductivity, such as stainless steel or aluminum alloy, to ensure that the heat generated by the heating element 30 can be efficiently transferred to the plate 20; alternatively, it can be made of high-temperature resistant ceramic or special glass materials to meet specific usage requirements and aesthetic needs. The shielding plate 15 is located between the shielding cavity 11 and the mounting cavity 12, forming a physical isolation and effectively blocking electromagnetic interference. The shielding plate 15 can be made of a metal material with good electrical conductivity, such as copper, aluminum, or galvanized steel plate, with grounding further enhancing the shielding effect; alternatively, it can be made of a non-metallic material with a conductive coating on its surface to ensure shielding performance while also considering lightweight or cost control requirements. The panel 14, shielding plate 15, and base 13 work together to define a shielding cavity 11, which effectively confines the electromagnetic radiation generated by the heating element 30 within it, forming a relatively enclosed shielding space. Furthermore, the shielding plate 15 and base 13 define a mounting cavity 12, thereby providing an independent and protected working environment for the functional component 40.

[0037] The shielding plate 15 is disposed between the shielding cavity 11 and the mounting cavity 12, thereby structurally achieving effective isolation between the shielding cavity 11 where the heating element 30 is located and the mounting cavity 12 where the functional component 40 is located. This ensures that the electromagnetic interference signal generated by the heating element 30 during operation is confined within the shielding cavity 11 and is unlikely to leak into the mounting cavity 12, thus significantly reducing interference to the functional components 40 such as the positioning module 41, the voice module 42, and the signal transmission module 43 within the mounting cavity 12.

[0038] Combination Figure 2 , Figure 8 and Figure 9 As shown, in some embodiments, the base 13 is provided with an antenna hole 131, which penetrates the base 13 along the wall thickness direction. The functional component 40 also includes an antenna 44, which includes a base portion 441 and a protrusion 442 connected to each other. The protrusion 442 is embedded in the antenna hole 131, and the base portion 441 is disposed in the mounting cavity 12. The positioning module 41 and the signal transmission module 43 are both signal connected to the base portion 441.

[0039] Antenna aperture 131 is an opening provided on the base 13 for accommodating antenna 44 and allowing signal penetration. Antenna aperture 131 extends through the base 13 along its wall thickness, thereby reducing signal attenuation and shielding effects caused by the material of the base 13. As an example, antenna aperture 131 can be a circular or rectangular through-hole, formed on the base 13 by casting or machining. The size and shape of antenna aperture 131 should match the protrusion 442 of antenna 44 to ensure a tight fit and efficient signal transmission. Furthermore, antenna aperture 131 can also have a chamfered structure to facilitate the installation and positioning of the protrusion 442 of antenna 44.

[0040] Antenna 44 includes an interconnected base portion 441 and a protrusion 442, thereby optimizing signal reception and internal connectivity. The base portion 441 can be the main body of antenna 44; for example, it may include the feed point and matching circuitry of antenna 44. The protrusion 442 can be the radiating portion of antenna 44. For example, the protrusion 442 can be integrally formed with the base portion 441, such as through welding, bonding, or co-molding. The base portion 441 can be designed to be flat to facilitate layout within the mounting cavity 12 and connection to other modules.

[0041] The protrusion 442 is embedded within the antenna hole 131, ensuring a stable installation of the antenna 44 on the base 13 and effectively exposing the radiating portion of the antenna 44 to the external environment, thus reducing signal obstruction by the base 13 material. As an example, the protrusion 442 can be embedded in the antenna hole 131 using an interference fit, secured by friction. Alternatively, the protrusion 442 can be fixed to the antenna hole 131 by means of snap-fit, threaded connection, or adhesive bonding, thereby improving the reliability and stability of the installation.

[0042] Both the positioning module 41 and the signal transmitting module 43 are signal-connected to the base 441, enabling the positioning module 41 to receive satellite signals for positioning via the antenna 44, and the signal transmitting module 43 to transmit data signals via the antenna 44. As an example, the signal connection can be achieved using coaxial cable, FPC cable, or direct soldering to ensure low signal loss and high reliability. During the connection process, impedance matching circuits can be used to optimize the signal transmission efficiency between the antenna 44 and the positioning module 41 and signal transmitting module 43, reducing signal reflection and loss.

[0043] By providing a through-hole antenna hole 131 on the base 13 and embedding the protrusion 442 of the antenna 44 into the antenna hole 131, the antenna 44 can effectively penetrate the shielding of the base 13, significantly reducing the signal attenuation and interference caused by the material of the base 13. The base 441 of the antenna 44 is located inside the mounting cavity 12, facilitating a direct and stable signal connection with the positioning module 41 and the signal transmission module 43. This allows the positioning module 41 to receive satellite signals more accurately, improving positioning accuracy and stability; and the signal transmission module 43 to transmit data more reliably, ensuring the integrity and real-time performance of data transmission.

[0044] Combination Figure 4 , Figure 8 and Figure 9 As shown, in some embodiments, the base 13 is also provided with a switching hole 132, and the functional component 40 also includes a battery 45 and a mounting module 46. The mounting module 46 is bonded to the base 13 and electrically connected to the mounting module 46. The battery 45 is installed on the mounting module 46 and corresponds to the switching hole 132. The mounting base 10 also includes a mounting cover 16, which is installed on the base 13 in a detachable manner.

[0045] The switching hole 132 can be a circular or rectangular opening, and the size of the switching hole 132 is larger than the external size of the battery 45 to match so that the battery 45 can be inserted or removed through the switching hole 132.

[0046] Battery 45 is an independent power unit that provides electrical energy, ensuring that functional components 40 can function normally without an external power connection, providing mobility and independence. As an example, battery 45 can be a rechargeable lithium-ion battery or a nickel-metal hydride battery to support the reusability of the device; battery 45 can also be a disposable battery, such as an alkaline battery, a button battery, or a carbon-zinc battery, to simplify power management.

[0047] The functional component 40 also includes a mounting module 46, which is used to fix and support the battery 45 and may provide an electrical connection interface. The mounting module 46 enables the battery 45 to be stably mounted within the housing 13 and provides a reliable electrical path between the battery 45 and the functional component 40. As an example, the mounting module 46 may be a PCB board integrating battery 45 management circuitry, with the battery 45 directly soldered or connected to the PCB board via a connection structure. The mounting module 46 is bonded to the housing 13 using adhesive, providing a strong and relatively permanent fixation to prevent loosening or displacement during device operation. For example, structural adhesives, such as epoxy resin or polyurethane adhesive, can be used to bond the mounting module 46 to the inner wall of the housing 13; alternatively, double-sided tape or pressure-sensitive adhesive can be used to form an adhesive between the mounting module 46 and the housing 13.

[0048] Mounting base 10 also includes a mounting cover 16, which covers and protects the components inside the switching hole 132 and mounting cavity 12, preventing dust, liquids, and other external substances from entering the device, protecting the battery 45 and functional components 40 from physical damage, and improving the overall aesthetics of the device. As an example, the mounting cover 16 can be a plastic or metal cover that matches the appearance of the base 13, secured by screws or clips; alternatively, the mounting cover 16 can be a waterproof or dustproof sealing cover that engages with the base 13 via a sealing ring, providing enhanced protection. The mounting cover 16 is detachably mounted to the base 13, ensuring quick and easy opening and closing when the battery 45 needs to be replaced or internal components need maintenance, thus improving the maintainability of the device.

[0049] A switching hole 132 is provided on the base 13 of the heating plate 100, and a battery 45 and a mounting module 46 are installed therein, so that the battery 45 is stably fixed by the mounting module 46 and reliably electrically connected to the functional component 40. The corresponding design of the switching hole 132 and the battery 45 position allows users to quickly and conveniently replace the battery 45 through the switching hole 132, greatly simplifying the maintenance process and saving maintenance time. The detachable mounting cover 16 not only protects the internal battery 45 and functional component 40 from the influence of the external environment, but also further improves the convenience of battery 45 replacement and internal maintenance, ensuring long-term stable operation of the equipment. As an independent power source, the battery 45 ensures that the functional component 40 can continue to operate when there is no external power source, enhancing the portability and flexibility of the equipment.

[0050] like Figure 3 , Figure 5 , Figure 7 and Figure 10 As shown, in some embodiments, the functional component 40 further includes a circuit board 47, in which the positioning module 41, the voice module 42, and the signal transmission module 43 are integrated. The mounting base 10 includes a socket 18 and a terminal block 17. The terminal block 17 is disposed in the mounting cavity 12. The positioning module 41, the voice module 42, and the signal transmission module 43 are all electrically connected to the terminal block 17. The socket 18 is disposed on the side wall of the base body 13 and is electrically connected to the terminal block 17.

[0051] It should be noted that, Figure 10 The diagram only provides an illustrative division of the positioning module 41, the voice module 42, and the signal transmission module 43. Those skilled in the art will understand that the positions of the positioning module 41, the voice module 42, and the signal transmission module 43 can be interchanged, and the positioning module 41, the voice module 42, and the signal transmission module 43 can also be mixed together.

[0052] By integrating the positioning module 41, voice module 42, and signal transmission module 43 onto the same circuit board 47, the positioning module 41, voice module 42, and signal transmission module 43 are arranged closely on the circuit board 47. This significantly reduces the physical distance between modules and the length of connecting cables, thereby reducing signal transmission loss and sensitivity to external electromagnetic interference. For example, the positioning module 41, voice module 42, and signal transmission module 43 can be directly soldered onto the circuit board 47 using surface mount technology (SMT); or the positioning module 41, voice module 42, and signal transmission module 43 can be designed as independent sub-modules and then fixed onto the main circuit board 47 by plug-in or soldering.

[0053] The positioning module 41, voice module 42 and signal transmission module 43 are all electrically connected to the terminal block 17, thereby avoiding the complexity of each module having its own cable, simplifying the internal wiring of the heating plate 100, and improving the reliability of the cable connection and the convenience of maintenance.

[0054] The socket 18 is located on the side wall of the base 13 and is electrically connected to the terminal block 17. The socket 18's location on the side wall of the base 13 makes it easily accessible from the outside, facilitating connection of external devices or power supply by users or maintenance personnel. The electrical connection between the socket 18 and the terminal block 17 enables power supply to the functional component 40.

[0055] The heating plate 100 of this application embodiment highly integrates the positioning module 41, the voice module 42 and the signal transmission module 43 onto the circuit board 47, which greatly simplifies the wiring structure inside the functional components 40, reduces the length and number of connecting cables between modules, and thus effectively reduces signal attenuation and crosstalk problems caused by complex and redundant wiring.

[0056] Furthermore, the centralized and standardized electrical interface formed by the terminal block 17 and the socket 18 simplifies the overall electrical connection management of the heating plate 100, reduces the difficulty of assembly and maintenance, and makes the connection between the functional component 40 and external equipment more convenient and safer.

[0057] Combination Figure 3 and Figure 7 As shown, in some embodiments, the functional component 40 further includes a speaker 48 and a microphone 49, both of which are located in the mounting cavity 12 and on the side of the circuit board 47 away from the shielding plate 15. Both the speaker 48 and the microphone 49 are electrically connected to the voice module 42.

[0058] By placing the speaker 48 and microphone 49 inside the mounting cavity 12, the mounting cavity 12 can effectively accommodate and protect the speaker 48 and microphone 49, protecting them from external physical damage and environmental factors.

[0059] The speaker 48 and microphone 49 are positioned on the side of the circuit board 47 away from the shielding plate 15, thereby placing the speaker 48 and microphone 49 away from the main electromagnetic interference source, thus reducing the electromagnetic interference received by the speaker 48 and microphone 49.

[0060] Combination Figure 2 , Figure 3 , Figure 6 and Figure 9 As shown, in some embodiments, the shielding plate 15 is provided with a protective part 151 and a plurality of first connecting posts 152 on the side opposite to the disk body 20. The protective part 151 covers at least a portion of the functional components 40. Along the extending direction of the protective part 151, the plurality of first connecting posts 152 are arranged sequentially at intervals. Each first connecting post 152 is connected to the protective part 151. The base body 13 is provided with a plurality of second connecting posts 133. The plurality of first connecting posts 152 and the plurality of second connecting posts 133 are connected one-to-one.

[0061] A protective portion 151 is provided on the side of the shielding plate 15 opposite to the disk body 20. The protective portion 151 can provide additional electromagnetic shielding protection for the functional components 40 within the mounting cavity 12. As an example, the protective portion 151 can be designed as a protruding structure integrally formed with the shielding plate 15, for example by stamping or injection molding, or it can be a cover manufactured separately and then mounted on the shielding plate 15 by welding, bonding, or screw fixing. The protective portion 151 covers at least a portion of the functional components 40, thereby enabling the protective portion 151 to further reduce the electromagnetic interference of at least a portion of the functional components 40.

[0062] Along the extending direction of the protective portion 151, a plurality of first connecting posts 152 are arranged sequentially at intervals, and each first connecting post 152 is connected to the protective portion 151. Thus, the strength of the shielding plate 15 can be strengthened by the first connecting posts 152 and the protective portion 151, thereby enhancing the impact resistance and vibration resistance of the shielding plate 15.

[0063] In this embodiment, the heating plate 100 has a protective portion 151 on the shielding plate 15 directly covering the functional component 40, which effectively reduces potential electromagnetic interference. Multiple first connecting posts 152 are connected to the protective portion 151 and correspondingly connected to multiple second connecting posts 133 on the base 13, forming a stable and reliable support structure. This enhances the overall structural strength of the protective portion 151 and the shielding plate 15, ensuring a tight fit between the shielding plate 15 and the base 13, thereby improving the sealing and anti-interference capabilities of the mounting cavity 12.

[0064] Combination Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, the disc body 20 includes a folded edge 21. Along the height direction of the mounting base 10, the folded edge 21 abuts against the base body 13 in a separable manner. Along the inward and outward directions of the mounting base 10, a portion of the folded edge 21 is inside the base body 13, and another portion of the folded edge 21 is outside the base body 13.

[0065] The flange 21 included in the disc body 20 is a structure that extends outward or inward from the edge of the disc body 20. The flange 21 can be an integrally formed flange, rolled edge or bent part, or it can be an additional structure connected by welding, riveting or bonding.

[0066] The folded edge 21 forms a separable abutment with the base 13 in the height direction of the mounting base 10, thereby allowing the plate 20 to be precisely positioned and stably supported in the height direction of the mounting base 10. This ensures good contact between the plate 20 and the heating element 30, thereby improving the heating efficiency and overall stability of the plate 20. Furthermore, it also ensures reliable contact between the plate 20 and the panel 14, further enhancing the structural integrity and performance of the heating plate 100.

[0067] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the plate body 20 includes a serving portion 22, a folded edge portion 21 is arranged around the serving portion 22 and connected to the serving portion 22, the serving portion 22 is installed in the base body 13 in a detachable form, and the serving portion 22 abuts against the panel 14.

[0068] Specifically, the serving section 22 is the area of ​​the plate 20 used to directly hold food. The serving section 22 can be integrally formed with the folded edge section 21, for example, by stamping, stretching or other processes to form an integral structure; or, the serving section 22 can be manufactured separately and then connected to the folded edge section 21 by welding, riveting, snap-fit ​​or other methods.

[0069] The circumferential connection of the folded edge 21 effectively enhances the structural integrity and stability of the food serving section 22. The food serving section 22 is detachably installed within the base 13, which not only facilitates cleaning and maintenance of the heating plate 100 but also ensures, through direct contact with the panel 14, that the heat generated by the heating element 30 is efficiently and evenly transferred to the food in the food serving section 22, avoiding heat loss and uneven heating. This improves the heating efficiency and ease of use of the heating plate 100.

[0070] like Figure 9 As shown, in some embodiments, the seat 13 is also provided with a plurality of reinforcing ribs 134. The plurality of reinforcing ribs 134 are spaced apart along the circumferential direction of the seat 13. One end of each reinforcing rib 134 is adapted to the shape of the folded edge portion 21 and abuts against the folded edge portion 21.

[0071] The reinforcing ribs 134 increase the resistance of the base 13 to deformation, thereby increasing the strength of the base 13. Multiple reinforcing ribs 134 are spaced apart along the circumferential direction inside the base 13 of the heating plate 100, and one end of each reinforcing rib 134 is adapted to the shape of the folded edge 21 and abuts against it. The additional support provided by the reinforcing ribs 134 makes the abutment between the plate 20 and the base 13 more stable, significantly enhancing the connection stability between the base 13 and the folded edge 21.

[0072] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
