Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular discloses a food heating spoon with an independently detachable battery module. Background Technology

[0002] Traditional heating spoons typically use an integrated battery and handle design, which has three significant drawbacks: First, the energy system is not replaceable; when the battery performance degrades or is completely depleted, the entire device becomes unusable. Second, the electrode connection stability is insufficient, and power outages are easily caused by vibration during frequent use. Third, functional expandability is poor; users cannot flexibly select battery modules of different capacities according to their usage scenarios. Especially when handling low-temperature solid foods, existing products suffer from a sharp drop in heating efficiency due to insufficient power supply, failing to meet the demands of high-intensity use. These structural defects severely limit the product's lifespan and user experience. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a heating device designed for taking high-viscosity, semi-solid foods. Specifically, it involves a heating spoon that enables quick replacement of battery components through a modular power supply system, which is especially suitable for kitchen scenarios that require instant heating, such as scooping ice cream and softening butter.

[0004] To achieve the above objectives, this utility model provides a battery module-independent detachable food heating spoon, comprising a handle and a spoon head assembly disposed on the handle. The handle contains a control module, and the spoon head assembly has a heating module electrically connected to the control module. It also includes a battery module, comprising a battery compartment, a lithium battery disposed within the battery compartment, and a first electrode for electrical connection with the lithium battery. The control module has a second electrode for electrical connection with the first electrode. The handle has a mounting cavity, and the control module is located within the mounting cavity. The lithium battery is detachably mounted within the mounting cavity via the battery compartment. When the battery compartment and lithium battery are installed in place, the first electrode and the second electrode contact and conduct to supply power to the control module and the heating module.

[0005] Furthermore, a magnetic attraction structure is provided between the battery module and the control module. The magnetic attraction structure includes a first magnet disposed on the battery compartment of the battery module and a second magnet disposed on the control module and / or the mounting cavity. The first magnet and the second magnet cooperate to attract and align the first electrode and the second electrode.

[0006] Furthermore, the battery module also includes a second bracket that can be detachably installed in the battery compartment. The second bracket has a mounting slot for accommodating the lithium battery. The first end of the second bracket is provided with a third electrode for contacting and conducting with the positive electrode of the lithium battery. The second end of the second bracket, away from the first end, is provided with a fourth electrode for contacting and conducting with the negative electrode of the lithium battery. The fourth electrode is used to electrically conduct with the first electrode when the second bracket is assembled into the battery compartment.

[0007] Furthermore, the spoon head assembly is detachably connected to the handle, the spoon head assembly is provided with a moving electrode group electrically connected to the heating module, and the control module has a stationary electrode group for electrically cooperating with the moving electrode group. The moving electrode group and the stationary electrode group contact and are electrically connected when the spoon head assembly is assembled with the handle on which the control module is mounted.

[0008] Furthermore, the control module includes a first bracket and a first circuit board disposed on the first bracket, the second electrode is disposed on the first bracket and electrically connected to a first end of the first circuit board; the static electrode group is disposed at a second end of the first circuit board.

[0009] Furthermore, the battery module also includes a charging circuit board and a charging interface disposed on the charging circuit board. The charging circuit board is disposed on the second bracket, and the power output terminal of the charging interface is electrically connected to the third electrode.

[0010] Furthermore, the food heating spoon also includes an end cap disposed at one end of the handle, the end cap being used to encapsulate the battery module and control module within the mounting cavity of the handle.

[0011] Furthermore, the spoon head assembly includes a base disposed at the end of the handle away from the mounting cavity and a spoon body disposed on the base. The heating module includes a heating element disposed between the spoon body and the base and a heat insulation pad used in conjunction with the heating element. The heating element is disposed close to the spoon body, and the heat insulation pad is disposed close to the base.

[0012] Furthermore, the food heating spoon also includes a switch module electrically coupled to the control module on the handle. The control module has a tactile switch, and the side wall of the handle has a first hole corresponding to the tactile switch. The switch module includes an external button movably disposed in the first hole, which is used to trigger the tactile switch when pressed.

[0013] Furthermore, the food heating spoon also includes a blind insertion structure, which includes a guide groove on the outer wall of the battery compartment and a guide rib on the inner wall of the mounting cavity of the handle. One end of the guide groove is provided with a guide groove communicating with it, and the width of the guide groove gradually increases along the direction in which the battery compartment is inserted into the mounting cavity.

[0014] Furthermore, a first waterproof component is provided between the outer button and the side wall of the handle, the first waterproof component being used to seal the gap between the outer button and the first hole.

[0015] Furthermore, the spoon body and the base are detachably installed and fitted by means of snap-fit ​​connection, interference fit connection or bolt connection, and a second waterproof component is provided between the spoon body and the base to seal the gap between the spoon body and the base.

[0016] Furthermore, the end cap is connected to the battery compartment, and the end cap is used to drive the battery compartment and the lithium battery contained in the battery compartment into the mounting cavity of the handle under the action of external force.

[0017] Furthermore, a third waterproof component is provided at one end of the first bracket. When the first bracket and the first circuit board are assembled into the mounting cavity, the third waterproof component is used to seal the gap between the first bracket and the mounting cavity.

[0018] The essence of this invention lies in reconstructing the power supply architecture of the heating spoon through modular design. Specifically, the traditional integrated structure is decomposed into three independent functional units: the battery module serves as an independent energy unit, carrying a lithium battery through a battery compartment, and forming a planar contact conductive circuit with the second electrode of the control module inside the handle via the first electrode at the end; the control module adopts an integrated design, fixing the first circuit board and electrode connector to a dedicated bracket to form a complete power control hub; and the spoon head module achieves blind-plug docking through an innovative electrode group distribution.

[0019] The beneficial effects of this utility model are as follows: In terms of ease of use, users can flexibly replace battery modules of different capacities according to actual needs, and the anti-misinsertion design of the interface effectively avoids incorrect assembly; in terms of product reliability, the unique electrode docking structure keeps the contact resistance at a stable low level, ensuring tight contact between the electrodes and effectively avoiding local overheating and energy loss caused by poor contact, thus extending the product's service life; in terms of economy, the modular design significantly extends the service life of the core control unit, while the standardized interface greatly reduces maintenance costs. This innovative design, by reconstructing the energy supply method of the heating spoon, achieves professional-grade equipment performance output while maintaining product portability.

[0029] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0030] Please see Figures 1 to 7As shown, this utility model discloses a battery module-independent detachable food heating spoon, comprising a handle 1, a spoon head assembly 2, a control module 10, and a battery module 3. The handle 1 is made of insulating material such as ABS plastic or nylon, and is roughly cylindrical in shape, with its diameter gradually tapering from one end to the other for easy gripping. It has an internal cylindrical mounting cavity 11. The mounting cavity 11 extends from one end of the handle 1 to the other. The control module 10 is fixedly mounted at the bottom of the mounting cavity 11. The control module 10 includes a first circuit board 104 and a microcontroller for managing power distribution and heating control.

[0031] The spoon head assembly 2 is connected to the front end of the handle 1 by threads or snaps. It contains a heating module 21 made of metal resistance foil or PTC ceramic, which is electrically connected to the output of the control module 10 via wires. The crucial battery module 3 is independent of the handle 1 body and includes a battery compartment 31 also made of engineering plastic, containing a standard cylindrical lithium battery 32 (such as an 18650 battery). The rear of the battery compartment 31 is embedded with metal spring pins (preferably four in this embodiment) serving as the first electrode 33. This first electrode 33 is connected to a fourth electrode 343 on the second bracket 34 via nickel strip spot welding or wires, thus serving as the negative output terminal of the battery module 3.

[0032] Accordingly, a connector serving as the second electrode 101 and four elastic pins are provided on the front end of the first circuit board 104 of the control module 10. When the user inserts the battery compartment 31 along the axial direction of the mounting cavity 11, the first electrode 33 and the second electrode 101 make physical contact and achieve circuit conduction, thereby establishing a complete power supply circuit from the lithium battery 32 to the control module 10 and finally to the heating module 21.

[0033] Compared to the fixed design where the battery and handle 1 are integrated in the existing technology, this solution uses a detachable independent battery module 3, which allows users to quickly replace the battery when it is depleted. This solves the problem of device power interruption caused by non-replaceable batteries and greatly improves the ease of use and practicality of the product.

[0034] Specifically, in this embodiment, to ensure the accuracy and convenience of the battery module 3 when docking with the control module 10, a magnetic attraction structure 4 is added. This structure includes a pair of permanent magnets, wherein the first magnet 41 is preferably a neodymium iron boron strong magnet, which is fixed to the outer peripheral wall of the front end of the battery compartment 31 by adhesive bonding or insert injection molding. The second magnet 42 is correspondingly fixed to the first bracket 103 of the control module 10 opposite to the first magnet 41 in the same way. In actual manufacturing, it can also be directly fixed to the inner wall of the mounting cavity 11 of the handle 1, in which case the position of the first magnet 41 can be adjusted to match it.

[0035] When the battery compartment 31 is inserted into the mounting cavity 11 and is close to being in place, the strong magnetic attraction between the first magnet 41 and the second magnet 42 will guide the battery compartment 31 to produce a small radial displacement and angular deflection, automatically correcting any possible assembly deviations, and ensuring that the first electrode 33 on the battery compartment 31 and the second electrode 101 on the control module 10 can be accurately aligned and in close contact.

[0036] Compared to the existing technology that relies solely on mechanical guides and user visual alignment for insertion, this solution utilizes the self-alignment properties of magnetism to achieve a "blind insertion" effect for electrode connections. This not only significantly reduces assembly difficulty but also effectively avoids problems such as arcing, increased resistance, and power reduction caused by poor contact by ensuring full contact of the electrodes, thereby improving the reliability and safety of electrical connections.

[0037] Specifically, in this embodiment, the internal structure of the battery module 3 has been optimized by introducing a detachable second bracket 34. This second bracket 34 is typically made of flame-retardant PC plastic and has an arc-shaped mounting slot 341 that matches the shape of a common cylindrical lithium battery 32. In actual manufacturing, it can be installed into the battery compartment 31 as a whole by sliding or snapping.

[0038] Specifically, at the end of the second bracket 34 facing the positive electrode of the lithium battery 32, a metal electrode sheet serving as the third electrode 342 is provided, which is connected to the circuit of the charging circuit board 35 via a wire; at the tail end of the second bracket 34, i.e. the end away from the positive electrode, a metal conductive sheet serving as the fourth electrode 343 is provided, which is used to contact the negative electrode of the lithium battery 32.

[0039] When the second bracket 34 carrying the lithium battery 32 is pushed into the battery compartment 31, the fourth electrode 343 will contact and conduct with the first electrode 33 (which serves as the main output electrode of the battery compartment 31) pre-fixed at the tail of the battery compartment 31. This hierarchical assembly structure of "battery-bracket-battery compartment 31" allows users to pre-install the lithium battery 32 on the second bracket 34 to form a standard power sub-module.

[0040] Compared to existing technologies where users directly insert bare cells into the battery compartment 31 by hand, which may lead to electrode scratches or reverse polarity, this solution uses a standardized second bracket 34 to not only standardize the battery loading direction and prevent misinstallation, but also provide additional cushioning and protection for the battery, thereby improving the assembly safety and service life of the entire power module.

[0041] In this embodiment, the functionality of the battery module 3 is further expanded by integrating an independent charging system. Specifically, a small charging circuit board 35 is fixed to one side of the second bracket 34 by screws or clips. The charging circuit board 35 integrates a lithium battery 32 charging management chip (such as TP4056), corresponding peripheral circuits, and a universal Micro-USB interface or a more advanced Type-C interface as a charging interface 351.

[0042] The positive and negative terminals of the power output of the charging interface 351 are electrically connected to the third electrode 342 (positive) and the fourth electrode 343 (negative) on the second bracket 34 via wires, respectively. Even without installing the battery module 3 into the handle 1, the user can use a standard data cable to connect the charging interface 351 to a 5V power source such as a mobile phone charger to directly charge the lithium battery 32 installed on the second bracket 34 independently.

[0043] Compared to existing technologies that require the entire heating spoon to be placed on a dedicated base or charged via a specific interface on the handle 1, this solution enables the battery module 3 to charge independently of the main device, greatly enhancing its flexibility. Users can prepare multiple fully charged battery modules 3 for rotation, achieving "ready to use and unlimited battery life," making it particularly suitable for scenarios where charging is inconvenient, such as outdoor picnics and long-distance travel.

[0044] Specifically, in this embodiment, a detachable modular electrical connection design is also adopted between the spoon head assembly 2 and the handle 1. Two metal contact posts serving as moving electrode groups are pre-embedded inside the base 23 of the spoon head assembly 2. These contact posts are reliably connected to the heating module 21 encapsulated inside the spoon body 24 via high-temperature resistant wires.

[0045] Correspondingly, two gold-plated spring pins or elastic copper alloy contacts, serving as static electrode groups, are provided on the front edge of the first circuit board 104 of the control module 10. When the user tightens the base 23 of the spoon head assembly 2 by screwing it in or snaps it into the front end of the handle 1 at a specific angle, the moving electrode group inside the base 23 will precisely align and press against the static electrode group on the first circuit board 104, thereby realizing the power transmission from the control module 10 to the heating module 21.

[0046] This design allows the spoon head assembly 2 to be separated from the handle 1 as an independent consumable or functional module. Compared to the existing technology where the spoon head and handle 1 are fixed together and the circuit is directly soldered through wires that are difficult to disassemble, this solution allows the spoon head assembly 2 to be easily replaced. Users can prepare spoon heads of different shapes, sizes, or materials as needed (such as soup spoons, ice cream spoons, and stir-fry spoons), and can even replace a single spoon head after it is damaged, without scrapping the entire device. This greatly enriches the product's functionality, reduces long-term usage costs, and facilitates deep cleaning or disinfection of the spoon head.

[0047] Specifically, in this embodiment, the mechanical structure of the control module 10 is described in detail. The control module 10 includes a first bracket 103 made of heat-resistant engineering plastic. The first bracket 103 is precisely positioned and fixed by engaging with a slot in the mounting cavity 11 of the handle 1 through a hook or positioning post on its outer wall.

[0048] The first circuit board 104 is mounted on the first bracket 103 by screws or clips. Its circuit layout is divided into two functional areas: the area at the rear end of the circuit board (near the insertion side of the battery module 3) is provided with the aforementioned second electrode 101, which is usually a pad or connector and is connected to the main circuit on the board through copper traces on the circuit board; the area at the front end of the circuit board (near the spoon assembly 2) is provided with the aforementioned static electrode group, which is usually an upright or side-standing spring pin connector.

[0049] The first bracket 103 plays a crucial role in supporting, positioning, and insulating the first circuit board 104, ensuring that the first circuit board 104 is in the correct position inside the handle 1 and that the second electrode 101 and the static electrode assembly on it are precisely aligned with the battery module 3 and the spoon head assembly 2, respectively.

[0050] Compared to existing technologies where circuit boards may be fixed with glue or simply clipped into the cavity, making them prone to displacement due to vibration or impact and resulting in poor contact, this solution provides a reliable mechanical foundation for the entire electrical control system through a structurally stable first bracket 103, ensuring the long-term stability of electrical connections between modules.

[0051] Specifically, in this embodiment, an end cap 5 assembly is designed for the tail end of the handle 1. This end cap 5 is typically also made of ABS plastic, and its inner wall has a threaded or snap-fit ​​structure that matches the outer wall of the battery compartment 31. The outer end face of the end cap 5 is typically designed with a raised first ring 51 or anti-slip texture to facilitate screwing on by the user.

[0052] When the battery module 3 (battery compartment 31 together with its internal second bracket 34 and lithium battery 32) is installed into the mounting cavity 11 of the handle 1, the user can indirectly apply an inward pressing force to the battery compartment 31 by tightening the end cap 5 and using the connection between the end cap 5 and the tail of the battery compartment 31. This force is ultimately transmitted through the battery compartment 31, making the first electrode 33 at its front end and the second electrode 101 of the control module 10 make a tighter and more reliable contact.

[0053] The end cap 5 serves a triple purpose: sealing the mounting cavity 11, providing dust and water protection, and ultimately locking the battery module 3. Compared to existing technologies where the battery compartment 31 may only rely on its own clips for fixation, which carries the risk of loosening, this solution, through the additional locking force provided by the end cap 5, further enhances the stability of the main power supply circuit connection and improves the overall structural integrity and protection level of the device.

[0054] Specifically, in this embodiment, the thermal management structure of the spoon head assembly 2 is detailed. The spoon head assembly 2 mainly includes a spoon body 24 made of metal (such as stainless steel or aluminum alloy) and a base 23 usually made of plastic. The heating module 21 specifically includes a heating element 211 (such as a metal thick film heating circuit or an etched foil heating element 211) attached to the inner side of the spoon body 24 and a heat insulation pad 212 placed between the heating element 211 and the base 23.

[0055] The heating element 211 is tightly attached to the inner surface of the spoon body 24 by thermally conductive silicone, ensuring that heat can be efficiently conducted to the working part of the spoon body 24. The heat insulation pad 212 is made of a material with low thermal conductivity, such as glass fiber, aerogel or high-temperature resistant silicone, and its function is to prevent heat from being transferred to the base 23 and the handle 1 connected to it.

[0056] This sandwich structure of "spoon body 24-heating element 211-heat insulation pad 212-base 23" allows the heat energy to be mainly concentrated in the working part of the spoon body 24 for rapid heating of food, while minimizing ineffective heat conduction towards the handle 1.

[0057] Compared to existing technologies where insufficient heat insulation design leads to the handle becoming hot to the touch and internal electronic components aging faster due to prolonged exposure to high temperatures, this solution, through meticulous thermal structure design, significantly improves user comfort while protecting internal circuitry and extending the device's lifespan.

[0058] Specifically, in this embodiment, a miniature tactile switch 105 is soldered onto the first circuit board 104 of the control module 10. A small hole, namely the first hole body 12, is precisely opened at a corresponding position on the side wall of the handle 1. The switch module 6 includes an external button 61, which is made of soft plastic. Its inner end is designed with a push rod for triggering the tactile switch 105, and its outer end is a curved surface for easy pressing by the user. The external button 61 is installed in the first hole body 12 through an interference fit between its peripheral flange and the first waterproof part 62 (molded in one piece of silicone, with a coverage area larger than the surface area of ​​the external button 61). It can move smoothly inward to trigger the switch when pressed, and can return to its original position when released by its own elasticity or the rebound force of the tactile switch 105.

[0059] In this embodiment, a button bracket 60 is provided at the first hole 12 as a carrier. The button bracket 60 has a button hole 601 for installing the external button 61. The external button 61 and the first waterproof component 62 are both assembled in the first button hole 601.

[0060] In this embodiment, the food heating spoon further includes a display unit, which includes a light-transmitting cover 63 covering the first hole 12. The first circuit board 104 of the control module 10 is provided with an LED display corresponding to the light-transmitting cover 63. The LED display displays the power of the battery module 3 and the heating power of the heating module 21 through the light-transmitting cover 63.

[0061] Compared to existing technologies that use mechanical levers or slide switches, which are prone to liquid ingress, dust accumulation, and a stiff feel, this solution uses a combination of a tactile switch 105 and an external button 61. This combination has a compact structure, good sealing (and can be used with waterproof components described later), a gentle and reliable operating feel, and improves the overall quality and durability of the product.

[0062] Specifically, in this embodiment, to further improve the ease of inserting the battery module 3, a mechanical blind insertion structure 7 is added. This structure includes at least one guide groove 71 provided on the outer wall of the battery compartment 31, and corresponding guide ribs 72 provided on the inner wall of the handle 1 mounting cavity 11.

[0063] The inlet end of the guide groove 71 is designed with a flared guide groove 73. The width of this groove gradually increases along the insertion direction of the battery compartment 31, forming an involute guide surface. When the user roughly aligns the battery compartment 31 with the opening of the mounting cavity 11 and inserts it, even if there is a certain angular or positional deviation, the guide rib 72 will first contact the inclined surface of the guide groove 73. During the continued insertion process, the guiding effect of the inclined surface will force the battery compartment 31 to rotate or translate slightly, eventually allowing the guide rib 72 to slide smoothly into the guide groove 71, thereby completing precise axial positioning.

[0064] This mechanical alignment structure can work in conjunction with the aforementioned magnetic alignment structure to provide dual protection. Compared to existing technologies that rely entirely on the user's visual inspection and touch for alignment, the blind insertion structure 7 in this solution greatly reduces assembly difficulty. Even in situations where it is inconvenient to observe, users can easily and quickly install the battery module 3, improving the user experience.

[0065] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
