[0018] The technical solution according to the exemplary embodiments of the present utility model solution is described clearly and completely below with reference to the accompanying drawings. Obviously, the described exemplary embodiments represent only a portion of the possible embodiments of the present utility model solution, but not its entire range. All further embodiments developed by a person skilled in the art without creative effort are protected under the present utility model. Example

[0019] How Fig. As shown, an embodiment of the present utility model device comprises an intelligent device unit for nutritional combination of foods, comprising the following components: Envelope 1, which has a recording chamber 11 and a display window 12 on its front. Magnetically attached module 2, integrated into housing 1; A touchscreen 3, which is located in the recording chamber 11 and whose display surface is aligned with the display window 12.

[0020] Both the main control module 4 and the UPS power supply module 5 are located in the receiving chamber 11 and are electrically connected to the touch display 3 and the UPS power supply module 5.

[0021] How Fig. As shown, the main control module 4 is a Raspberry Pi 5 in some versions.

[0022] As in Fig. As shown, the housing unit 1 in some embodiments comprises an outer housing 13 and a rear cover plate 14 which is detachably connected to the outer housing 13; the magnetic fastening module 2 is arranged on the side of the rear cover plate 14 which is oriented outwards towards the outer surface of the outer housing 13.

[0023] The housing unit 1 consists of the outer housing 13 and the rear cover 14 as separate components. The rear cover 14 is detachably connected to the outer housing 13. The receiving chamber 11 is located inside the outer housing 13, and the magnetic mounting module 2 is arranged directly on the rear side of the rear cover 14, facing the outer housing 13.

[0024] The separate housing design 1 facilitates the assembly of the individual components inside the devices and subsequent maintenance. By integrating the magnetic mounting module 2 on the outside of the rear cover 14, the device can adhere directly and securely to ferromagnetic surfaces such as a refrigerator door during installation. This allows the usage scenarios to be precisely adapted to the storage locations of the food and significantly simplifies operation.

[0025] How Fig. As shown, in some embodiments the magnetic fastening module 2 comprises at least two fastening slots 21 arranged on the rear cover 14, each containing an embedded magnet 22.

[0026] The shape of the magnet 22 is adapted to that of the fixed handle 21 and is firmly embedded in it, so that the attraction plane of the magnet 22 protrudes slightly outwards.

[0027] By inserting the magnet 22 into the fixed mounting slots 21, its position can be precisely controlled and an even distribution of the attractive force can be ensured. Embedding the magnet 22 in the slots 21 effectively prevents it from shifting or falling off during use, thus ensuring a reliable long-term magnetic attachment, which in turn keeps the device firmly attached to the wing surface.

[0028] How Fig. As shown, in some embodiments, clamping blocks 15 are arranged at all four corners of the receiving chamber 11, while at the four corners of the back of the cover plate 14 a clamping lock 16 is provided which is locked precisely with each clamping block 15.

[0029] In the four corners of the cavity 11 formed by the housing 13, protruding locking areas 15 are provided. At the four corresponding corners of the rear cover 14, which project outwards into the cavity 11, there are inwardly directed locking elements 16. During the assembly process, the locking elements 16 of the rear cover 14 are aligned and inserted into the locking areas 15 of the housing 13, thereby achieving secure locking and fastening between the two components.

[0030] The use of a locking mechanism with a four-angled clamping block 15 and clamping lock 16 enables quick and secure, tool-free installation and removal between the housing 13 and the back cover 14. This design simplifies the assembly process, avoids visual defects that could arise from the use of screws, and thus ensures a slimmer, more attractive appearance as well as easier maintenance.

[0031] As in Fig. In some embodiments, a main control plate 17 is also provided in the receiving chamber 11, on which both the main control module 4 and the UPS power supply module 5 are mounted.

[0032] In the receiving chamber 11 of the housing 1, a self-contained main control plate 17 is arranged, on which the main control module 4 and the UPS power supply module 5 are mounted using screws. The main control plate 17 serves as an independent support structure and integrates the central electronic control components (main control module 4) and the power supply components (UPS power supply module 5) into a single unit. This modular assembly allows for organized wiring of the devices, increases the utilization of the interior space, enhances the structural stability and vibration damping of the core components, and also facilitates mass production and assembly.

[0033] How Fig. As shown, in some embodiments a switch button 18 is arranged on one side of the housing 13, below which the power connection socket 19 is located.

[0034] A hole for mounting the physical button 18 is provided on the side of the housing 13. The power connection socket 19 is located on the housing 13 in close proximity to the button. The physical button 18 and the power connection socket 19 are concentrated on the same side of the housing 13, which facilitates user access and allows them to quickly locate the device's basic control and power connection points. The physical button 18 enables direct and reliable control of the power connection, thus increasing the user's sense of security when operating the device.

[0035] As in Fig. As shown, in some embodiments a loudspeaker hole 131 is provided on one side of the housing 13, and inside the receiving chamber 11 there is a loudspeaker 111 which corresponds to the position of the loudspeaker hole 131.

[0036] Several finely arranged loudspeaker tubes 131 are provided on the front of the housing 13. Loudspeakers 111 are installed in the receiving chamber 11 of the housing 1, corresponding to the positions of the loudspeaker tubes 131, with the loudspeakers 111 being oriented such that their loudspeaker openings are either directed directly at the loudspeaker tubes 131 of the housing 13 or are connected to them via a sound conductor.

[0037] Through the special speaker opening 131 on the housing 13, which is precisely aligned with the internal speaker 111, voice prompts, operating feedback, and other audio signals are clearly and undisturbed transmitted to the outside world of the device. This provides the user with an additional, important information channel alongside the visual interaction via the touchscreen display 3, thus improving the user experience.

[0038] As in Fig. As shown, a touch device 132 is arranged on one side of the housing 13, on the side of the loudspeaker 131. Inside the receiving chamber 11 is a fixed holder 112, which corresponds to the position of the touch device 132, and a touch switch 113 is integrated therein.

[0039] Specific touch sensors 132 are printed or engraved on the front panel of the housing plate 13 near the loudspeaker 131. A fixing bracket 112 is attached directly behind the area of ​​the touch sensors 132 on the inner wall of the receiving chamber 11. A touch switch 113 is mounted in this bracket 112, its receiving surface being precisely aligned with the touch sensors 132 on the inside of the housing plate 13.

[0040] The touch marker 132 on the housing 13 guides the user intuitively: Touching the marker area triggers the internal touch switch 113 via capacitive induction. The fixing holder 112 ensures precise and stable positioning of the switch. This design enables quick and user-friendly functions – such as voice activation – expands the interaction possibilities, and simultaneously ensures a clean, uncluttered appearance for the device.

[0041] As in Fig. As shown, connecting horns 31 are attached to the top and bottom of the touch display 3 in some embodiments. In the receiving chamber 11, fastening straps 114 are provided at the upper and lower positions of the display window 12, the ends of which are equipped with screw holes 115 that fit the connecting horns 31.

[0042] The frame of the touch display 3 has connecting horns 31 with through holes 32 on its upper and lower edges. In the housing 13, in the receiving chamber 11, horizontal mounting straps 114 are attached along the upper and lower edges of the display window 12, with screw holes 115 provided at both ends of each mounting strap 114. During the assembly process, the touch display 3 is attached to the mounting rod 114 via its connecting horn 31 and inserted into the screw recess 115 of the mounting rod 114 with a screw that passes through the through hole 32 of the connecting horn 31, thereby firmly anchoring the touch display 3.

[0043] Connecting the connecting tube 31 to the mounting disc 114 with screws provides the touch display 3 with a stable and removable mount. This mounting method effectively dampens vibrations and shocks during use, prevents the display from loosening or shifting, and thus ensures the tightness of the display window 12 and the structural reliability of the entire system. At the same time, the replaceability and repairability of the touch display 3 remain unaffected.

[0044] As in Fig. In some embodiments, the touch switch 113, the loudspeaker 111 and the switch button 18 are each electrically connected to the main control module 4.

[0045] The touch switch 113, the speaker 111 and the physical button 18 are electrically connected via conductors or flexible circuit boards to the corresponding control, audio output and power supply connections of the main control module 4.

[0046] As in Fig. As shown, at least two positioning steps 116 are provided on each side of the inner wall of the receiving chamber 11. Corresponding pressure pieces 171 are attached to the positioning steps 116 on the main control plate 17, which lock into place with the positioning steps 116.

[0047] The main control plate 17 is adjusted to the limit step 116 by the pressure piece 171 attached to it and clamped in place, thus achieving an initial positioning of the plate. After the rear cover 14 is locked to the housing 14, the main control plate 17 is further compressed to ensure its final fixation.

[0048] The hardware equipment mainly comprises the core control unit, the human-machine interaction unit, and the structural mounting unit. First, the Raspberry Pi 5 processing unit, serving as the main control module 4, and the UPS power supply module 5, which provides a stable power supply, are mounted and secured together on the hard drive 17 of the main control module, thus creating the central electronic control module; then, the entire module is installed in the receiving chamber 11 of the housing 13. Subsequently, a touchscreen 3 is installed in the prepared display window 12 on the front of the housing 13, which serves as the central interface for information output and manual input. A physical switch button 18 for controlling the device's power supply is located on the side of the housing 13, supplemented by an integrated touch switch module 113 for quick function activation.A fixed magnet 22 is installed and secured in the designated mounting slot 21 in the rear housing 14, thus completing the assembly of the device housing. This enables convenient and stable attachment to ferromagnetic surfaces such as refrigerators.

[0049] The main control module 4 (Raspberry Pi 5) implements a complete software system on the hardware platform. This integrates a large language modeling engine (LLM), quantitative calculation algorithms based on nutritional science, and control programs for the individual functional modules, together enabling the following core functions: Module for entering ingredient information: It offers an input mode with two options. The user can either enter data manually via the touch display area 3 or activate voice input by pressing the touch switch 113. The collected voice commands are analyzed by the integrated large language model to process natural language. This allows ingredient names, quantities, and other important data to be precisely recognized and extracted – a simple and reliable way to capture ingredient information. Module for defining user requirements: It offers a structured human-machine interaction to allow the input of personal physiological data such as age, gender, to support body size and weight. In addition, multidimensional nutritional goals are offered via a checkbox selection, covering health care, body control, specific groups (e.g., pregnant women and women in postpartum care, people with chronic illnesses), and personal taste preferences. Furthermore, users can manually enter allergens, agreed-upon foods, and specific cooking conditions—such as low oil or no spices—to create a comprehensive profile of their individual needs.

[0050] Module for holistic food management: When entering ingredients, users can synchronously set their purchase date and expiration date or recommended storage time. The system automatically integrates all entered information and generates a dynamic, visual inventory list. Using integrated time and comparison algorithms, the system automatically sends a notification via a pop-up window on the touchscreen 3 when the expiration date is approaching, thus proactively preventing food waste.

[0051] Intelligent Recipe Generation (Data Processing): This module acts as the system's central decision-making hub, combining semantic understanding and association recommendation functions from large language models with the scientific calculation of logic-based nutritional formulas from classical nutritional science. By linking the user's defined individual needs and nutritional goals with current ingredient inventory data, the module performs a comprehensive analysis and intelligent allocation, generating one or more personalized meal plans that take into account the current availability of ingredients, individual health goals, and personal taste preferences. The results are then displayed on touchscreen 3, allowing the user to use them for orientation and selection.

[0052] To operate the device, the user first starts it using a physical button. They can then enter the available ingredients either manually via the touchscreen 3 or using voice commands via touch switch 113. Next, the user enters their personal data, nutritional goals, and dietary restrictions, guided by the touchscreen 3. Once the settings are complete, an automatically generated inventory list of available ingredients is displayed on the main interface, accompanied by automatic expiration warnings. Users can request the creation and use of personalized recipe plans at any time, based on their current inventory and personal profile.

[0053] In summary, the magnetic mounting module 2, integrated into the housing 1, allows the device to be easily and securely attached to a surface such as a refrigerator. The operating scenarios are perfectly suited to food storage and are particularly practical. The combination of two input methods—the touch display 3 and voice control via the touch switch 113—supplemented by the physical switch 18 on the housing 13, accommodates different user preferences. The low barrier to entry and the modular design—consisting of the main control module 4 and the UPS power supply module 5, which are attached to the hard drive module 17 via a removable housing 1, a terminal block 15, and a clamping mechanism 16—significantly simplify installation and maintenance.This ensures the reliability of the design and the accuracy of the system interaction, creating a stable, user-friendly hardware base for managing food and nutritional combinations.
