They also lack components that visually display the operating status, making it difficult for users to monitor the device's operation. Overall, the user experience and safety need improvement. 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 spoon that is easy to install and remove batteries.

[0004] To achieve the above objectives, the present invention provides a heating spoon with an easy-to-install and remove battery, comprising a handle assembly, a spoon body assembly and a back cover assembly respectively disposed at both ends of the handle assembly, wherein the back cover assembly is detachably connected to the handle assembly, the spoon body assembly is provided with a heating module, and the handle assembly includes a spoon handle with a hollow cavity, wherein the spoon handle contains a control module and a lithium battery, and the control module is electrically connected to the lithium battery and the heating module respectively.

[0005] By designing the back cover assembly and handle assembly as detachable connections, the lithium battery is easily installed and removed, facilitating battery replacement or maintenance. The hollow cavity of the spoon handle provides reasonable housing space for the control module and lithium battery, resulting in a compact overall structure. The electrical connection design between the control module, lithium battery, and heating module ensures stable heating function, meeting users' basic needs for a heated spoon, while the rational structural layout facilitates miniaturization.

[0006] Furthermore, the handle assembly also includes a support frame located in the hollow cavity of the spoon handle and a battery compartment located on the support frame. The control module is located on the support frame, and the battery compartment is used to house a lithium battery.

[0007] The support frame provides a stable mounting base for the control module and battery compartment, improving the structural stability of internal components and reducing shaking and collisions during use.

All these connection methods ensure a reliable fit between the back cover assembly and the spoon handle, while simplifying battery replacement, improving the user experience, and enhancing the product's practicality and adaptability.

[0010] Furthermore, the battery compartment has a first electrode group and a second electrode group at opposite ends. The first electrode group is electrically connected to the control module and the lithium battery, and the second electrode group is electrically connected to the lithium battery. The lithium battery has a protrusion and a groove at both ends. The first electrode group includes a first electrode plate on the support frame, an electrode hole on the first electrode plate, and a telescopic spring coaxially arranged with the electrode hole. The second electrode group has an electrical protrusion. When the lithium battery compresses the telescopic spring, the protrusion passes through the telescopic spring and abuts against the electrode hole. The electrical protrusion abuts against the groove.

[0011] The precise fit between the electrode assembly and the lithium battery end structure ensures the stability and reliability of the circuit connection. The telescopic spring design allows the lithium battery to be firmly held in place during installation, preventing poor contact due to vibration, and facilitating easy insertion and removal. The fit between the protrusions and electrode holes, and between the protrusions and recesses, enables directional installation of the lithium battery, preventing reverse installation and ensuring safety. This structural design guarantees good conductivity while improving the ease of battery installation and removal, enhancing product safety and usability.

[0012] Furthermore, the second electrode assembly includes a second electrode sheet disposed in the battery compartment and a third electrode sheet disposed in the rear cover assembly. The second electrode sheet is snapped into the battery compartment and has a through hole for inserting the lithium battery into the battery compartment. The third electrode sheet is circumferentially provided with a pressure spring for pressing the second electrode sheet. The second electrode sheet and the third electrode sheet are electrically connected through the pressure spring.

[0013] The snap-fit ​​design between the second electrode and the battery compartment facilitates the installation and fixation of the electrode, while the perforated structure does not interfere with the insertion of the lithium battery. The pressure spring ensures a tight electrical connection between the second and third electrode plates, guaranteeing stable conductivity even under slight vibrations during use. This split electrode design simplifies the battery compartment structure, ensures reliable electrode connections, and facilitates the assembly and disassembly of the back cover and handle components, improving product assembly efficiency and operational stability.

[0014] Furthermore, the spoon body assembly and the handle assembly are detachably connected. The spoon body assembly is provided with a moving electrode group electrically connected to the heating module, and the handle assembly is provided with a static electrode group electrically connected to the control module. The moving electrode group and the static electrode group are electrically connected. The support frame is provided with a support column, and both the static electrode group and the moving electrode group are provided with mounting holes corresponding to the support column.

[0015] The detachable connection between the spoon body assembly and the handle assembly facilitates cleaning, replacement, or individual maintenance of the spoon body, enhancing the product's practicality and lifespan. The cooperation between the moving and stationary electrode groups ensures effective circuit conduction when the spoon body assembly and handle assembly are connected, guaranteeing normal operation of the heating function. The fit between the support post and the mounting hole enables precise positioning and installation of the spoon body assembly and handle assembly, preventing misalignment during connection that could lead to poor electrode contact, thus improving assembly convenience and connection stability.

[0016] Furthermore, the first connecting part and the second connecting part are connected by a snap-fit ​​to achieve a detachable fit. The back cover assembly has an encapsulated back cover, the encapsulated back cover is provided with a screw-fit part, and the spoon handle is provided with a snap-fit ​​part. The encapsulated back cover and the spoon handle are engaged after being screwed together by the screw-fit part and the snap-fit ​​part.

[0017] The snap-fit ​​connection is simple to operate; users can install and remove the back cover assembly simply by rotating it, saving time and effort. The cooperative design of the screw-on and snap-fit ​​parts ensures that the sealed back cover and spoon handle are both securely and reliably connected, while also allowing for quick separation and easy battery replacement. This connection structure requires no additional tools, improving user convenience while ensuring a tight connection to prevent the back cover from accidentally falling off during use, thus enhancing product safety.

[0018] Furthermore, the inner side of the encapsulation cover is provided with encapsulation ribs for encapsulating lithium batteries, and the outer side of the encapsulation cover is provided with a pull ring for easy handling.

[0019] The encapsulation ribs further secure and limit the lithium battery, preventing it from shifting within the handle and ensuring stable electrode connections, while also enhancing the battery's encapsulation effect. The pull ring design provides a convenient point of leverage for removing the back cover assembly, making the disassembly process easier, especially for users with less hand strength. These thoughtful design details improve the product's ease of use and safety, enhancing the user experience.

[0020] Furthermore, the control module includes a PCB assembly mounted on a support frame. The support frame is provided with a limiting member for limiting the PCB assembly and a threaded post for fixing the PCB assembly. The threaded post cooperates with a screw to screw the PCB assembly onto the support frame.

[0021] The limiting components precisely position the PCB assembly, ensuring accurate mounting on the support frame and facilitating circuit connections with other components. The threaded posts and screws securely fix the PCB assembly, preventing loosening or displacement due to vibration during use and ensuring stable operation of the control module. This fixing method is simple in structure, reliable in connection, and facilitates PCB assembly installation and maintenance, improving production efficiency and ease of maintenance.

[0022] Furthermore, a display component electrically connected to the control module is embedded in the spoon handle, and a waterproof structure is provided between the control module and the display component; waterproof rings are provided between the handle assembly and the spoon body assembly, and between the handle assembly and the back cover assembly.

[0023] The display component allows users to intuitively understand the heating spoon's operating status, such as temperature and battery level, improving ease of use. The waterproof structure and waterproof ring effectively prevent water or other liquids from entering the internal circuitry and battery area, preventing short circuits or damage and ensuring product safety and lifespan. These designs enable the heating spoon to adapt to more humid environments, enhancing product reliability and safety.

[0024] Furthermore, the inner wall of the battery compartment is provided with guide ribs extending along the length direction, and the outer peripheral surface of the battery is provided with guide grooves adapted to the guide ribs. The guide ribs and guide grooves cooperate to restrict the circumferential rotation of the battery within the battery compartment.

[0025] The guide ribs inside the battery compartment work in conjunction with the guide grooves on the outer periphery of the battery to effectively restrict the battery's circumferential rotation within the compartment. This prevents the battery from shifting due to movement, ensuring the stability of electrode contact and reducing the possibility of poor circuit contact. Simultaneously, the guide structure acts as a guide during battery installation, helping users quickly align the battery in the installation position, improving battery installation and removal efficiency. This is especially beneficial for users unfamiliar with the product structure, reducing the probability of operational errors.

[0026] The beneficial effects of this utility model are as follows: The heating spoon features a detachable back cover and handle, and offers multiple connection methods, facilitating lithium battery installation, removal, and maintenance.

[0032] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0033] Please see Figures 1 to 4As shown, the present invention provides a heating spoon with easy battery installation and removal, comprising a handle assembly 1, a spoon body assembly 2 and a back cover assembly 3 respectively disposed at both ends of the handle assembly 1, the back cover assembly 3 being detachably connected to the handle assembly 1, the spoon body assembly 2 being provided with a heating module 4, the handle assembly 1 including a spoon handle 5 having a hollow cavity, the spoon handle 5 containing a control module 7 and a lithium battery 9, the control module 7 being electrically connected to the lithium battery 9 and the heating module 4 respectively.

[0034] In actual use, the lithium battery 9 serves as the power source, providing electrical energy to the entire heating spoon. When heating is required, the control module 7 receives an operation command (such as a user-triggered switch), then obtains and regulates electrical energy from the lithium battery 9, transmitting a stable current to the heating module 4 in the spoon body assembly 2. After the heating module 4 is powered on, its internal heating elements (such as heating wires, PTC heating elements, etc.) convert electrical energy into heat energy, raising the temperature of the spoon body to meet the needs of heating food. When heating is not required or the power is insufficient, the control module 7 can cut off the circuit and stop the heating module 4 from working. The detachable design of the back cover assembly 3 and the handle assembly 1 allows for easy removal of the lithium battery 9 for charging or replacement when the lithium battery 9 is depleted, ensuring continuous use of the heating spoon. Throughout the process, the hollow spoon handle 5 provides installation space for the control module 7 and the lithium battery 9, while also protecting the internal components from external impacts and contamination.

[0035] In actual use, after the heating spoon has finished retrieving materials (such as frozen ice cream, frozen grease, etc.), the spoon body component 2 needs to be cleaned. At this time, the user removes the back cover component 3, takes out the lithium battery 9, and then reinstalls the back cover component 3. The heating spoon can then be placed in clean water or cleaning solution for cleaning. After cleaning, the heating spoon should be allowed to air dry. Once dry, the lithium battery 9 can be reinserted into the spoon handle 5.

[0036] Specifically, the handle assembly 1 also includes a support frame 6 disposed in the hollow cavity of the spoon handle 5 and a battery compartment 8 disposed on the support frame 6. The control module 7 is disposed on the support frame 6, and the battery compartment 8 is used to accommodate a lithium battery 9.

[0037] During assembly and use, the support frame 6 is fixedly installed inside the hollow cavity of the spoon handle 5. Its main function is to provide a stable mounting platform for the control module 7 and the battery compartment 8, preventing internal components from shifting or being damaged due to shaking during the use of the heating spoon. The battery compartment 8 is fixed on the support frame 6, and the lithium battery 9 can be directly placed into the battery compartment 8. The size of the battery compartment 8 matches that of the lithium battery 9, which can position and limit the lithium battery 9, preventing it from shaking freely inside the spoon handle 5 and ensuring the stability of the electrical connection between the lithium battery 9 and the control module 7.

[0038] The control module 7 is fixed to the support frame 6 by screws and other connectors, ensuring the stability of the control module 7 during operation and preventing poor contact between the control module 7 and the lithium battery 9 and heating module 4 due to vibration. When the lithium battery 9 needs to be replaced, after removing the back cover assembly 3, the old lithium battery 9 can be directly taken out from the battery compartment 8, and then the new lithium battery 9 can be placed into the battery compartment 8. The operation is convenient and does not require disassembling the entire handle assembly 1, which greatly improves the efficiency of battery replacement. At the same time, the presence of the support frame 6 also makes the internal component layout more organized, which is convenient for later maintenance and repair.

[0039] Specifically, the spoon handle 5 is provided with a first connecting part 11, and the rear cover assembly 3 is provided with a second connecting part 12 adapted to the first connecting part 11. The first connecting part 11 and the second connecting part 12 are detachably connected by threaded connection, snap-fit ​​connection or magnetic connection.

[0040] In actual assembly and disassembly operations, there are specific implementation procedures for different connection methods. If a threaded connection is used, the first connecting part 11 of the spoon handle 5 has an external thread structure, and the second connecting part 12 of the rear cover assembly 3 has an internal thread structure. During assembly, align the second connecting part 12 of the rear cover assembly 3 with the first connecting part 11 of the spoon handle 5, and rotate the rear cover assembly 3 clockwise to gradually engage the threads until the rear cover assembly 3 and the spoon handle 5 are tightly fitted together, thus achieving fixation. During disassembly, rotate the rear cover assembly 3 counterclockwise to remove it from the spoon handle 5. If a snap-fit ​​connection is used, the first connecting part 11 has an elastic snap, and the second connecting part 12 has a corresponding slot. During assembly, align the rear cover assembly 3 with the spoon handle 5 and press it down. The elastic snap deforms under pressure and snaps into the slot, completing the fixation. During disassembly, pinch a specific part of the spoon handle 5 or the rear cover assembly 3 to disengage the elastic snap from the slot, thus separating the two.

[0041] If a magnetic connection is used, the first connecting part 11 and the second connecting part 12 are respectively equipped with mutually attractive magnets (such as neodymium iron boron magnets) with opposite polarities. During assembly, simply bring the back cover assembly 3 close to the spoon handle 5, and under the action of magnetic force, the second connecting part 12 and the first connecting part 11 will automatically adhere and fit together, achieving a quick connection. During disassembly, apply a certain external force to overcome the magnetic force, and the back cover assembly 3 can be removed. All three connection methods can achieve convenient assembly and disassembly of the back cover assembly 3 and the handle assembly 1, meeting the needs of different usage scenarios, while ensuring the sealing and stability after connection.

[0042] Specifically, the battery compartment 8 has a first electrode group 13 and a second electrode group 14 at opposite ends. The first electrode group 13 is electrically connected to the control module 7 and the lithium battery 9, respectively, and the second electrode group 14 is electrically connected to the lithium battery 9. The lithium battery 9 has a protrusion and a groove at both ends. The first electrode group 13 includes a first electrode plate 15 disposed on the support frame 6, an electrode hole 16 disposed on the first electrode plate 15, and a telescopic spring 17 coaxially disposed with the electrode hole 16. The second electrode group 14 has an electrical protrusion 18. When the lithium battery 9 compresses the telescopic spring 17, the protrusion passes through the telescopic spring 17 and abuts against the electrode hole 16. The electrical protrusion 18 abuts against the groove.

[0043] During the installation and power supply process of the lithium battery 9, the end of the lithium battery 9 with the protrusion is first aligned with the end of the battery compartment 8 where the first electrode group 13 is located. During installation, the lithium battery 9 is pushed into the battery compartment 8, and the protrusion contacts and compresses the telescopic spring 17 of the first electrode group 13. As the lithium battery 9 continues to be pushed in, the telescopic spring 17 continues to be compressed until the protrusion passes through the telescopic spring 17 and precisely engages with the electrode hole 16 on the first electrode plate 15. At this time, under the elastic force of the telescopic spring 17, the lithium battery 9 is tightly pressed, ensuring stable contact between the protrusion and the electrode hole 16, realizing the electrical connection between the first electrode group 13 and the lithium battery 9. The first electrode group 13 has been pre-connected to the control module 7, thereby establishing a current path between the lithium battery 9 and the control module 7.

[0044] Meanwhile, the end of the lithium battery 9 with the groove is opposite to the end of the battery compartment 8 where the second electrode group 14 is located. When the lithium battery 9 is fully installed in the battery compartment 8, the electrical protrusion 18 of the second electrode group 14 precisely matches and abuts against the groove of the lithium battery 9, realizing the electrical connection between the second electrode group 14 and the lithium battery 9. Through this dual electrode connection structure, the electrical contact stability between the lithium battery 9 and the electrode group can be effectively guaranteed, avoiding poor contact caused by vibration or shaking, ensuring stable power transmission to the control module 7, and thus powering the heating module 4. When removing the lithium battery 9, pull the lithium battery 9 outward, the protrusion disengages from the electrode hole 16, the telescopic spring 17 returns to its original state, the electrical protrusion 18 disengages from the groove, and the lithium battery 9 can be easily removed. The operation is simple and convenient.

[0045] Specifically, the second electrode group 14 includes a second electrode sheet 19 disposed in the battery compartment 8 and a third electrode sheet 21 disposed in the rear cover assembly 3. The second electrode sheet 19 is snapped into the battery compartment 8 and has a through hole for inserting the lithium battery 9 into the battery compartment 8. The third electrode sheet 21 is circumferentially provided with a pressure spring 22 for pressing the second electrode sheet 19. The second electrode sheet 19 and the third electrode sheet 21 are electrically connected through the pressure spring 22.

[0046] During the assembly and electrical connection of the second electrode assembly 14, the second electrode piece 19 is first fixed in the battery compartment 8 by a snap-fit ​​mechanism. The snap-fit ​​structure ensures that the second electrode piece 19 is fixed in position within the battery compartment 8, preventing displacement. The perforated design on the second electrode piece 19 facilitates the smooth passage of the lithium battery 9 during installation, ensuring that the lithium battery 9 can be properly installed into the battery compartment 8.

[0047] During assembly of the back cover assembly 3, the third electrode plate 21 is first fixed inside the back cover assembly 3, with the circumferential pressure spring 22 of the third electrode plate 21 facing the second electrode plate 19. When the back cover assembly 3 is connected and fixed to the handle assembly 1, the back cover assembly 3 moves the third electrode plate 21 closer to the second electrode plate 19 until the pressure spring 22 contacts and is compressed against the second electrode plate 19. Under the elastic force of the pressure spring 22, the third electrode plate 21 and the second electrode plate 19 are tightly pressed together. Since the electrode plates are all made of conductive material, a stable electrical connection is achieved between the second electrode plate 19 and the third electrode plate 21.

[0048] This press-fit electrical connection structure, achieved through the pressure spring 22, effectively compensates for dimensional errors during assembly. Even with slight assembly deviations, the spring force of the pressure spring 22 ensures tight contact between the two components, preventing poor contact. Furthermore, when the rear cover assembly 3 is disassembled, the third electrode plate 21 detaches from the second electrode plate 19, and the pressure spring 22 returns to its original position, without affecting subsequent reassembly and electrical connection. In addition, the snap-fit ​​structure between the second electrode plate 19 and the battery compartment 8 facilitates future maintenance or replacement of the second electrode plate 19. Simply remove the old second electrode plate 19 from the snap-fit ​​position in the battery compartment 8 and replace it with a new one; the operation is convenient.

[0049] Specifically, the spoon body assembly 2 is detachably connected to the handle assembly 1. The spoon body assembly 2 is provided with a moving electrode group 23 electrically connected to the heating module 4, and the handle assembly 1 is provided with a static electrode group 24 electrically connected to the control module 7. The moving electrode group 23 is electrically connected to the static electrode group 24. The support frame 6 is provided with a support column 25, and both the static electrode group 24 and the moving electrode group 23 are provided with mounting holes 26 corresponding to the support column 25.

[0050] During the assembly, electrical connection, and use of the spoon body assembly 2 and the handle assembly 1, the static electrode assembly 24 is first aligned with the support column 25 on the support frame 6 through its assembly hole 26. The static electrode assembly 24 is then fitted onto the support column 25 and fixed to ensure that the static electrode assembly 24 is in a stable position and electrically connected to the control module 7. Subsequently, the moving electrode assembly 23 of the spoon body assembly 2 is similarly fitted onto the support column 25 through its assembly hole 26, so that the moving electrode assembly 23 and the static electrode assembly 24 are precisely aligned.

[0051] Due to the cooperation between the support column 25 and the mounting hole 26, the moving electrode group 23 and the stationary electrode group 24 can be quickly positioned, ensuring accurate contact between their electrode contacts, thereby achieving electrical connection between the moving electrode group 23 and the stationary electrode group 24. At this time, the control module 7 can transmit electrical energy to the heating module 4 of the spoon body assembly 2 through the stationary electrode group 24 and the moving electrode group 23, supplying power to the heating module 4 and realizing the heating function.

[0052] When it is necessary to replace the spoon assembly 2 (e.g., to replace it with a spoon of a different size or shape) or to clean the spoon assembly 2, simply pull the spoon assembly 2 off the support column 25. This will separate the moving electrode assembly 23 from the stationary electrode assembly 24, thus completing the disassembly of the spoon assembly 2. This detachable connection and electrode assembly structure not only facilitates the replacement and maintenance of the spoon assembly 2 but also ensures the stability of the electrical connection, preventing poor electrode contact due to spoon shaking during use and thus avoiding impact on heating performance. Simultaneously, the support column 25 also provides support and protection for the moving electrode assembly 23 and the stationary electrode assembly 24, extending the service life of the electrode assembly.

[0053] Specifically, the first connecting part 11 and the second connecting part 12 are connected by a snap-fit ​​to achieve a detachable fit. The back cover assembly 3 has an encapsulated back cover 27, the encapsulated back cover 27 is provided with a screw-fit part 28, and the spoon handle 5 is provided with a snap-fit ​​part 29. The encapsulated back cover 27 and the spoon handle 5 are engaged and snap-fitted together after being screwed on by the screw-fit part 28 and the snap-fit ​​part 29.

[0054] In the specific implementation process of using snap-fit ​​connection to assemble and disassemble the back cover assembly 3 and the handle assembly 1, the encapsulated back cover 27 is the main component of the back cover assembly 3, and its screw-fit part 28 can be designed as a protrusion structure with a guide bevel, while the snap-fit ​​part 29 of the spoon handle 5 is designed as an L-shaped slot that matches the protrusion.

[0055] During assembly, first align the screw-on portion 28 of the encapsulated back cover 27 with the entrance position of the snap-fit ​​portion 29 of the spoon handle 5. Then, rotate the encapsulated back cover 27 clockwise. The protrusion of the screw-on portion 28 slides along the guide slope of the snap-fit ​​portion 29. As the rotation angle increases, the protrusion gradually enters the transverse section of the L-shaped slot. When rotated to a preset angle (e.g., 90 degrees), the protrusion reaches the end of the L-shaped slot. At this point, the encapsulated back cover 27 can no longer rotate, and the screw-on portion 28 and the snap-fit ​​portion 29 engage, fixing the encapsulated back cover 27 to the spoon handle 5. This screw-on and snap-fit ​​structure effectively prevents the encapsulated back cover 27 from falling off due to vibration or collision during use, ensuring the stability of the connection.

[0056] During disassembly, simply rotate the encapsulated back cover 27 counterclockwise to retract the protrusion of the screw-on part 28 along the transverse section of the L-shaped slot to the inlet position. Then, pull the encapsulated back cover 27 outward to remove it from the spoon handle 5. The operation is simple and convenient, requiring no tools. Simultaneously, after the encapsulated back cover 27 is connected to the spoon handle 5, it provides a sealing protection for components such as the lithium battery 9 and control module 7 inside the spoon handle 5, preventing dust and moisture from entering and affecting the normal operation of the components.

[0057] Specifically, the inner side of the encapsulation cover 27 is provided with encapsulation ribs 31 for encapsulating the lithium battery 9, and the outer side of the encapsulation cover 27 is provided with a pull ring 32 for easy handling.

[0058] In the actual use and operation of the encapsulation cover 27, the role of the encapsulation rib 31 is crucial. After the encapsulation cover 27 is connected and fixed to the spoon handle 5, the encapsulation rib 31 on the inner side of the encapsulation cover 27 abuts against the end of the lithium battery 9 in the battery compartment 8. The encapsulation rib 31 is made of a material with a certain degree of elasticity (such as silicone, elastic plastic, etc.). During the abutment process, the encapsulation rib 31 will produce slight elastic deformation, applying a certain pressure to the lithium battery 9, and firmly fixing the lithium battery 9 in the battery compartment 8. This prevents the lithium battery 9 from losing contact with the electrode assembly due to shaking or vibration during the use of the heating spoon, ensuring the stability of the electrical connection.

[0059] Meanwhile, the encapsulation ribs 31 can also fill the gap between the lithium battery 9 and the encapsulation cover 27, playing a sealing role and preventing external dust and moisture from entering the battery compartment 8 through the connection gap between the encapsulation cover 27 and the spoon handle 5, thus affecting the performance and lifespan of the lithium battery 9. The pull ring 32 on the outside of the encapsulation cover 27 plays an important role in removing the encapsulation cover 27.

[0060] When it is necessary to remove the back cover 27 to replace or recharge the lithium battery 9, the user only needs to hook the pull ring 32 with their finger and apply outward pulling force (if it is a screw-on or snap-fit ​​structure, rotate it first and then pull) to easily remove the back cover 27 from the spoon handle 5. The design of the pull ring 32 increases the contact area between the hand and the back cover 27, reducing the difficulty of disassembly. Especially when the back cover 27 is tightly connected to the spoon handle 5 or the hands are wet, it can effectively prevent slippage, improve the convenience of disassembly, and enhance the user experience.

[0061] Specifically, the control module 7 includes a PCB assembly disposed on the support frame 6. The support frame 6 is provided with a limiting member 34 for limiting the PCB assembly and a threaded post 35 for fixing the PCB assembly. The threaded post 35 cooperates with a screw to screw the PCB assembly onto the support frame 6.

[0062] During the assembly and fixing of the control module 7, the PCB assembly (printed circuit board assembly, integrating electronic components such as control chips, capacitors, and resistors) is first placed on the carrier frame 6. The limiting components 34 on the carrier frame 6 (such as limiting bosses, limiting baffles, etc.) will block and position the PCB assembly around its perimeter, enabling the PCB assembly to quickly find the accurate installation position on the carrier frame 6, avoiding displacement of the PCB assembly during assembly, and ensuring that the interfaces and solder joints on the PCB assembly can accurately connect with other components (such as the lithium battery 9 and the electrode group of the heating module 4).

[0063] After positioning, using the threaded post 35 on the support frame 6, pass the screw through the preset mounting hole on the PCB assembly, align it with the threaded post 35, and tighten it clockwise. The screw and the threaded post 35 engage, generating a tightening force to firmly fix the PCB assembly on the support frame 6, preventing the PCB assembly from shifting or falling off due to vibration or shaking during the use of the heating spoon, and ensuring the stability of the control module 7.

[0064] This method of positioning via limiters 34 and fixing via threaded posts 35 and screws not only ensures high assembly precision but also facilitates later maintenance. When a PCB assembly malfunctions and requires repair or replacement, simply unscrew the screws counterclockwise to remove the PCB assembly from the support frame 6. After repair, re-fix it following the same steps. The operation is convenient and eliminates the need for damaging disassembly of the support frame 6 or other components, reducing maintenance costs. Simultaneously, the stable fixing structure protects the electronic components on the PCB assembly from damage caused by collisions and vibrations, extending the service life of the control module 7.

[0065] Specifically, a display component 36 electrically connected to the control module 7 is embedded on the spoon handle 5, and a waterproof structure 37 is provided between the control module 7 and the display component 36; waterproof rings 38 are provided between the handle assembly 1 and the spoon body assembly 2, and between the handle assembly 1 and the back cover assembly 3.

[0066] During the operation of the display component 36 and the waterproofing of each component, the display component 36 (such as an LED display screen, digital tube, etc.) is embedded in the spoon handle 5 and electrically connected to the control module 7 via wires. During operation, the control module 7 converts relevant operating parameters of the heating spoon (such as current temperature, remaining power, heating level, etc.) into electrical signals and transmits them to the display component 36. After being powered on, the display component 36 displays these parameters intuitively in the form of numbers, icons, etc., allowing users to understand the working status of the heating spoon in real time and adjust the operation as needed.

[0067] The waterproof structure 37 (such as waterproof adhesive, waterproof sealing ring, waterproof connector, etc.) between the control module 7 and the display component 36 can effectively prevent external moisture and liquids from entering the connection points between the two, preventing short circuits and component damage caused by moisture intrusion, and ensuring that the display component 36 can normally receive signals transmitted by the control module 7 and operate stably. At the connection points between the handle assembly 1 and the spoon body assembly 2, and between the handle assembly 1 and the back cover assembly 3, waterproof rings 38 (made of elastic waterproof materials such as silicone and rubber) are respectively installed on the corresponding connection surfaces.

[0068] When the handle assembly 1 is connected and fixed to the spoon body assembly 2 and the back cover assembly 3, the connecting surfaces press against each other to create a waterproof ring 38, causing the waterproof ring 38 to undergo elastic deformation and tightly fill the gaps at the connection points, forming a sealing barrier. This sealing structure effectively prevents external water, soup, dust, and other impurities from entering the handle assembly 1, avoiding damage to internal components such as the control module 7, lithium battery 9, and electrode assembly due to moisture or contamination. This greatly improves the waterproof performance and service life of the heating spoon, allowing it to be used safely in humid environments such as kitchens, and even to a certain extent, it can be washed and cleaned (subject to meeting the product's waterproof rating requirements).

[0069] The working principle of this utility model is as follows: In daily use, the heating spoon is powered by a lithium battery 9, and the power regulation and function triggering are achieved through the control module 7 inside the handle assembly 1. Before use, the lithium battery 9 must be inserted into the battery compartment 8 on the support frame 6 inside the hollow cavity of the spoon handle 5: align the end of the lithium battery 9 with the protrusion with the first electrode group 13 of the battery compartment 8, and compress the telescopic spring 17 during the pushing process until the protrusion passes through the spring and abuts against the electrode hole 16 of the first electrode plate 15. At the same time, the end of the lithium battery 9 with the groove precisely matches the electrical protrusion 18 of the second electrode group 14. The spring force and electrode structure ensure a stable electrical connection between the lithium battery 9 and the control module 7. Then, the spoon handle 5 is sealed by the detachable connection (thread, snap, or magnetic) between the back cover assembly 3 and the spoon handle 5. At this time, the sealing ribs 31 on the inner side of the back cover 27 further tighten the lithium battery 9 to prevent it from shaking, and the outer pull ring 32 provides a convenient operation point for subsequent disassembly.

[0070] When heating is required, the user triggers an operation command (such as pressing a switch). The control module 7 (whose core is a PCB assembly fixed on the support frame 6, positioned by the limiter 34 and secured by the threaded post 35 and screws) receives the command, obtains electrical energy from the lithium battery 9, and performs voltage stabilization and current limiting regulation. Then, through the static electrode group 24 of the handle assembly 1 and the moving electrode group 23 of the spoon body assembly 2 (the two are precisely connected by the support post 25 and the mounting hole 26), a stable current is transmitted to the heating module 4 of the spoon body assembly 2. After the heating element or PTC heating element inside the heating module 4 is energized, it quickly converts electrical energy into heat energy, raising the temperature of the spoon body to meet the heating needs of freezing ice cream and melting grease. At the same time, the display component 36 on the spoon handle 5 is electrically connected to the control module 7, displaying parameters such as the current temperature and remaining power in real time, allowing the user to easily monitor the working status. The waterproof structure 37 between the two prevents water vapor from affecting signal transmission and component safety.

[0071] When the heating spoon needs cleaning after handling materials, or when the lithium battery 9 is depleted, its structural design allows for convenient maintenance and continuous use. Before cleaning, the user can remove the back cover assembly 3 by pulling the ring 32 (e.g., by screwing on the threads, pressing the buckle, or overcoming the magnetism) and directly remove the lithium battery 9 from the battery compartment 8. Then, the user can reinstall the back cover assembly 3. The waterproof ring 38 at the connection between the handle assembly 1, the back cover assembly 3, and the spoon body assembly 2 forms a sealed barrier, allowing the heating spoon to be placed in clean water or cleaning solution for cleaning, preventing internal components from getting damp. The waterproof ring 38 fills the connection gaps through elastic deformation, and together with the waterproof structure 37 of the display assembly 36, it protects the core components such as the control module 7 and the electrode assembly from water contamination.

[0072] After cleaning and drying or after the lithium battery 9 has been fully charged, reinsert the lithium battery 9 into the battery compartment 8 and close the back cover assembly 3. The heating spoon can then be used again. If a spoon with a different function needs to be replaced, simply pull the spoon assembly 2 off the support column 25 to separate the moving electrode group 23 from the stationary electrode group 24. After replacement, reattach the support column 25 through the assembly hole 26 to complete the connection, ensuring a stable electrical connection. Throughout the process, the hollow spoon handle 5 provides installation and protection space for the internal components, while the support frame 6 enhances component stability through its orderly layout, ultimately achieving an integrated user experience that features controllable heating function, convenient battery installation and removal, and safe cleaning and maintenance.
