Description

Technical Field

[0001] This utility model relates to the field of small household appliance technology, and in particular to a liquid heating container. Background Technology

[0002] In traditional cooking, a regular kettle heats water using a heating plate at the bottom to dissolve nutrients in the food, thus extracting them. However, the release of some nutrients involves complex chemical reactions that require time to complete. Therefore, within the limited cooking time, not all nutrients can be effectively extracted, potentially leading to underutilization or even waste.

[0003] Traditional heating methods typically heat only from the bottom, which can result in uneven or inefficient heat transfer to the food, further affecting the effective extraction of nutrients. To overcome these problems, it is necessary to explore new heating technologies and methods to more effectively utilize cooking time and ensure that more nutrients are fully preserved and extracted. Utility Model Content

[0004] To address the aforementioned technical problems, this application proposes a design that uses two electrode sections (a positive electrode section and a negative electrode section) spaced apart in the kettle and connected to an electronic control device. This accelerates the movement of negative particles from the food towards the positive electrode section and positive particles towards the negative electrode section, thereby achieving extraction. To ensure effective operation of both electrode sections, they must be completely submerged in the liquid simultaneously. However, in actual use, as the user gradually pours out the liquid, the water level drops, potentially causing the electrode sections to emerge from the water. Ensuring that both electrode sections remain submerged at all times, thus guaranteeing effective extraction of nutrients, is a further challenge faced by this design.

[0005] The main purpose of this invention is to provide a liquid heating container that solves the problem that the liquid heating container cannot perform extraction normally when the water level drops.

[0006] To achieve the above objectives, the liquid heating container proposed in this utility model includes: The pot body has a receiving cavity with an opening at the top; A first electrode portion and a second electrode portion, one of which is configured as an anode and the other as a cathode, are disposed on the pot body or inside the receiving cavity, and at least one of the first electrode portion and the second electrode portion is movably disposed inside the receiving cavity in the vertical direction; Heating assembly for heating the liquid within the receiving cavity; and, An electronic control device is electrically connected to the first electrode section and the second electrode section.

[0007] In one embodiment, the first electrode portion is disposed on the kettle body, and the second electrode portion is disposed within the receiving cavity; The liquid heating container also includes a lid covering the opening, and an adjustment structure is provided between the lid and the second electrode portion so that the position of the second electrode portion can be adjusted in the vertical direction.

[0008] In one embodiment, the lid of the kettle is provided with a limiting hole in the vertical direction, and the adjustment structure includes a mounting shaft. The upper end of the mounting shaft passes through the limiting hole, and the lower end of the mounting shaft is connected to the second electrode part. The mounting shaft is movably arranged in the vertical direction to drive the second electrode part to move up and down. A limiting structure is provided between the lid and the mounting shaft, the limiting structure being used to limit the mounting shaft in the vertical direction.

[0009] In one embodiment, the limiting structure includes a first magnetic part and a second magnetic part respectively disposed on the lid and the second electrode part, wherein the first magnetic part is used to magnetically attract the second magnetic part when the second electrode part is close to the lid.

[0010] In one embodiment, the limiting structure includes an internal thread formed on the inner wall of the limiting hole; The mounting shaft is provided with an external thread that is screwed into the internal thread.

[0011] In one embodiment, the limiting structure further includes a limiting member installed on the lid of the kettle. The limiting member is disposed on the side of the mounting shaft and is used to abut against the side of the mounting shaft to radially limit the mounting shaft.

[0012] In one embodiment, the limiting structure further includes a positioning part and a plurality of mating parts respectively disposed on one side of the limiting hole and the mounting shaft. The plurality of mating parts are spaced apart in the vertical direction. When the mounting shaft moves up and down, the positioning part can be positioned and mated with each of the mating parts.

[0013] In one embodiment, the adjustment structure includes a telescopic shaft that can be extended and retracted, the upper end of the telescopic shaft being connected to the lid of the kettle, and the lower end of the telescopic shaft being connected to the second electrode portion.

[0014] In one embodiment, the liquid heating container further includes a driving device having a driving part movably disposed in the vertical direction, the driving part being connected to the second electrode part to drive the second electrode part to move up and down.

[0015] In one embodiment, the adjustment structure further includes a rotating part and a traction member. One end of the traction member is connected to the rotating part and is wound around the rotating part. The other end of the traction member is connected to the second electrode part. The rotating part is rotatably arranged about a rotation axis extending in a first horizontal direction, and is used to wind and unwind the traction member so that the second electrode part can move up and down.

[0016] In one embodiment, the liquid heating container further includes a bottom plate and sidewalls surrounding the receiving cavity, wherein at least a portion of the bottom plate is made of a conductive material, and at least a portion of the bottom plate constitutes the first electrode portion; and / or, The first electrode and the second electrode are made of titanium alloy, platinum alloy or carbon rod.

[0017] In the technical solution of this utility model, the first and second electrode parts inside the pot can effectively adsorb positive and negative particles of food in the liquid through the action of electric field and electrostatic attraction, thereby enhancing the solubility of food in the liquid or releasing nutrients. By setting at least one electrode part to be movable in the vertical direction, it remains submerged even when the user pours the liquid to the lowest water level. The movable electrode part automatically or manually adjusts its height according to the real-time water level, always being submerged in the liquid together with the fixed electrode, thereby maintaining a stable electric field and avoiding electrode exposure or electric field interruption due to water level drop. This ensures the continuity and integrity of nutrient extraction and solves the problem that the liquid heating container cannot perform extraction normally when the water level drops.

[0025] Traditional heating methods typically heat only from the bottom, which may result in uneven or inefficient heat transfer to the food. This application proposes using two electrodes (a positive electrode and a negative electrode) connected to an electronic control device, spaced apart in the middle of the kettle. This accelerates the movement of negative particles from the food towards the positive electrode and positive particles towards the negative electrode, thus achieving extraction. To ensure effective operation of both electrodes, they must be completely submerged in the liquid. However, in actual use, as the user gradually pours out the liquid, the water level drops, potentially exposing the electrodes. Ensuring that both electrodes remain submerged at all times to guarantee effective nutrient extraction is a further challenge this design faces.

[0026] This invention proposes a liquid heating container 100, which aims to solve the problem that the liquid heating container cannot perform extraction normally when the water level drops.

[0027] Please see Figure 1In one embodiment of this utility model, the liquid heating container 100 includes a pot body 1, a first electrode portion 10, a second electrode portion 20, a heating assembly 2, and an electronic control device 3. The pot body 1 has a receiving cavity a with an opening at the upper end. One of the first electrode portion 10 and the second electrode portion 20 is set as an anode, and the other is set as a cathode. The first electrode portion 10 and the second electrode portion 20 are disposed on the pot body 1 or in the receiving cavity a. At least one of the first electrode portion 10 and the second electrode portion 20 is movably disposed in the receiving cavity a in the vertical direction. The heating assembly 2 is used to heat the liquid in the receiving cavity a. The electronic control device 3 is electrically connected to the first electrode portion 10 and the second electrode portion 20.

[0028] It is understood that the vessel body 1 is an open container with an internal cavity a for holding the liquid to be heated. The vessel body 1 may be made of a high-temperature resistant material, and its bottom or side walls may be provided with a support structure to fix other components.

[0029] It should be noted that the liquid heating container 100 can be a health pot or an electric kettle, or it can be an electric slow cooker, a heating cup or a food processor, etc. Of course, other possible household appliances can also be used. The specific method can be determined according to the actual situation. This specification does not limit this embodiment.

[0030] The first electrode section 10 and the second electrode section 20 are the anode and the cathode, respectively. Negative particles are adsorbed near the anode, and positive particles are adsorbed near the cathode. This is used to accelerate the directional movement of positive and negative ions in the liquid through the action of an electric field to achieve the extraction of nutrients.

[0031] The two electrode sections are spaced a certain distance apart within the receiving cavity a to ensure effective current flow in the liquid. It is understood that the two electrode sections can be spaced apart vertically, horizontally, or even at an angle. As long as the two electrode sections are spaced apart and arranged opposite each other, an electric field can be generated in the water when energized.

[0032] At least one electrode is movably disposed in the receiving cavity a in the vertical direction via a sliding guide rail, telescopic rod or similar structure, so as to adjust its immersion depth according to changes in the liquid level.

[0033] For example, the first electrode part 10 can be driven to move up and down along the guide groove on the side wall of the pot body 1 by a screw screw or electric push rod, or its height can be adjusted by a manual knob.

[0034] It should be noted that the electrode part can be made of conductive metal (such as stainless steel or copper) and can be set in the shape of a rod, sheet or other suitable shape to enhance the contact area with the liquid.

[0035] The heating component 2 is disposed at the bottom or side wall of the kettle body 1, for example, a heating plate or heating tube, and is used for conventional heating of the liquid in the receiving cavity a. The heating component 2 can be configured as an electric heating tube, an electric heating plate, an electric heating wire, a ceramic heating element, or induction heating, etc. The specific design can be based on actual conditions, and this specification does not limit it in this embodiment.

[0036] The electronic control device 3 includes a power supply module, a control circuit, and a switch module, used to provide DC or AC power to the electrode section and control the polarity (anode / cathode) switching of the electrode section. Furthermore, the electronic control device 3 can integrate a water level detection sensor (such as a float switch or a capacitive liquid level sensor) to monitor the liquid level in real time and control the raising and lowering of the movable electrode section in conjunction with the liquid level, ensuring that it is always submerged in the liquid.

[0037] For example, when the water level is detected to have dropped to a preset threshold, the electronic control device 3 drives the movable electrode to move downwards below the new water level line to maintain the effectiveness of the electric field.

[0038] Specifically, when the electronic control device 3 is powered on, current flows through the two electrode sections, forming an electric field. The presence of this electric field exerts a force on surrounding charged particles. If the first electrode section 10 carries a positive charge (or exhibits a positive charge through current), it will attract nearby negatively charged particles. If the second electrode section 20 carries a negative charge (or exhibits a negative charge through current), it will attract nearby positively charged particles. Electrochemical reactions occur between the ions in the liquid; cations (positive particles) in the food move towards the cathode, and anions (negative particles) in the food move towards the anode.

[0039] In the technical solution of this utility model, the first electrode part 10 and the second electrode part 20 inside the pot body 1 can effectively adsorb positive and negative particles of food in the liquid through the action of electric field and electrostatic attraction, thereby enhancing the solubility of food in the liquid or releasing nutrients. By setting at least one electrode part to be movable in the vertical direction, it remains submerged even when the user pours the liquid to the lowest water level. The movable electrode part automatically or manually adjusts its height according to the real-time water level, and is always submerged in the liquid together with the fixed electrode, thereby maintaining a stable electric field and avoiding electrode exposure or electric field interruption caused by water level drop. This ensures the continuity and integrity of nutrient extraction and solves the problem that the liquid heating container 100 cannot perform extraction normally when the water level drops.

[0040] It is understandable that charged particles are released within the containing cavity a, meaning that positively charged particles move towards the negative electrode and negatively charged particles move towards the positive electrode. The movement of these charged particles is itself a manifestation of electric current. Therefore, a microcurrent will be formed in the liquid within the vessel 1. Figures 11 to 18 This is a graph showing the relationship between microcurrents and time detected in the liquid within the receiving cavity a for various types of food ingredients. Figure 11 and Figure 12 Let's take an example to illustrate: Figure 11 These are the microcurrent values ​​detected by existing technology for hibiscus flowers in liquid at different times. Figure 12 These are the microcurrent values ​​detected in the hibiscus flower at different times in the liquid when the first electrode part 10 and the second electrode part 20 of this utility model are energized.

[0041] according to Figure 11 It can be seen that when the food is submerged in the liquid for 1 minute, the detected microcurrent is approximately 172uA; after 2 minutes, the detected microcurrent is approximately 170uA; after 3 minutes, the detected microcurrent is approximately 172uA; and after 4 minutes, the detected microcurrent is approximately 170uA.

[0042] according to Figure 12 It can be seen that during the period from 1 minute to 5 minutes when the food was submerged in the liquid, the detected microcurrent rapidly increased from about 150uA to about 420uA; at 10 minutes, the detected microcurrent was about 420uA; at 15 minutes, the detected microcurrent was about 350uA; and at 20 minutes, the detected microcurrent was about 300uA.

[0043] Data shows that, under the same conditions, when using the microcurrent extraction function of the electrode section to brew hibiscus tea, the microcurrent value in the tea water will increase rapidly in a short period of time, indicating that the concentration of charged particles in the tea water will increase rapidly, thus accelerating the nutrient extraction effect.

[0044] Specifically, in one embodiment, the first electrode portion 10 is disposed on the kettle body 1, and the second electrode portion 20 is disposed in the receiving cavity a; the liquid heating container 100 further includes a kettle lid 5 covering the opening, and an adjustment structure 4 is provided between the kettle lid 5 and the second electrode portion 20 so that the position of the second electrode portion 20 can be adjusted in the vertical direction.

[0045] The first electrode part 10 is fixedly installed on the side wall or bottom of the pot body 1, while the second electrode part 20 is suspended inside the receiving cavity a by a support structure. The second electrode part 20 can be moved in the vertical direction by the adjustment structure 4 to dynamically adjust the distance between it and the first electrode part 10.

[0046] The adjustment structure 4 is mechanically connected to the second electrode section 20, for example, through a gear-rack structure, electric push rod, screw screw, or slide rail to achieve up-and-down driving. The adjustment structure 4 can be manually driven or controlled by the electronic control device 3. Based on the real-time water level data detected by the liquid level sensor, it automatically adjusts the second electrode section 20 to a suitable height so that it is always submerged in the liquid along with the first electrode section 10.

[0047] The second electrode 20 can dynamically adjust its height through the adjustment structure 4, so that it can always maintain the optimal distance from the electrode on the bottom plate 11. At the same time, it can adjust the distance according to the water level, so as to ensure that the electric field intensity uniformly covers the liquid volume, thereby improving the ion migration efficiency and the nutrient extraction effect.

[0048] Specifically, please refer to Figures 4 to 9 In some embodiments, the lid 5 has a limiting hole b extending vertically; the adjusting structure 4 includes a mounting shaft 41, the upper end of which passes through the limiting hole b, and the lower end of which is connected to the second electrode part 20. The mounting shaft 41 is movably arranged vertically to drive the second electrode part 20 to move vertically; a limiting structure 6 is provided between the lid 5 and the mounting shaft 41, which is used to limit the mounting shaft 41 in the vertical direction.

[0049] It is understood that the lid 5 covers the opening of the body 1 and has a through-hole b for the mounting shaft 41 to pass through. The diameter of the through-hole b is slightly larger than the outer diameter of the mounting shaft 41 to allow the mounting shaft 41 to slide freely, while the limiting structure 6 (such as a groove or threaded locking element) prevents the mounting shaft 41 from radially shifting.

[0050] The lower end of the mounting shaft 41 is mechanically connected to the second electrode part 20, such as by threaded fixing or snap-fit ​​structure. By rotating or sliding up and down, the mounting shaft 41 can be moved up and down, thereby adjusting the height of the second electrode part 20.

[0051] The limiting structure 6 is disposed between the lid 5 and the mounting shaft 41, for example, by a baffle on the inner side of the lid 5 or a boss on the mounting shaft 41, to limit the vertical movement range of the mounting shaft 41.

[0052] This embodiment provides a limiting hole b on the lid 5 and connects the second electrode 20 via a mounting shaft 41, allowing the user to manually or automatically adjust the electrode position according to the current water volume, ensuring it remains submerged in the liquid and maintaining the electric field effect. Simultaneously, the limiting structure 6 effectively controls the vertical movement range of the mounting shaft 41, preventing the second electrode 20 from detaching from the liquid or impacting the bottom of the kettle body due to improper operation or accidental contact.

[0053] Further, please refer to Figure 5In this embodiment, the limiting structure 6 includes a first magnetic attraction part 61 and a second magnetic attraction part 62 respectively disposed on the lid 5 and the second electrode part 20. The first magnetic attraction part 61 is used to magnetically attract the second magnetic attraction part 62 when the second electrode part 20 is close to the lid 5.

[0054] With this configuration, when the second electrode 20 moves upward with the mounting shaft 41 and approaches the lid 5, a magnetic attraction is generated between the two magnetic components, thereby stably holding the second electrode 20 at a certain height. This magnetic attraction can provide auxiliary positioning during user adjustment or automatic equipment control, preventing unnecessary displacement of the second electrode 20 due to liquid fluctuations or vibrations.

[0055] By setting a magnetic attraction limiting structure between the lid 5 and the second electrode part 20, the second electrode part 20 can be automatically attracted and fixed when it rises to a specific position, making the electrode less prone to shaking or displacement and improving the stability after adjustment.

[0056] Specifically, please refer to Figures 1 to 3 In one specific embodiment, the limiting structure 6 includes an internal thread formed on the inner wall of the limiting hole b; the mounting shaft 41 is provided with an external thread that is screwed into the internal thread.

[0057] The inner wall of the limiting hole b is machined with internal threads, and the outer surface of the mounting shaft 41 is correspondingly provided with external threads. Through the screw engagement of the internal and external threads, the rotational motion of the mounting shaft 41 is converted into a lifting motion. By rotating the mounting shaft 41, the height of the second electrode section 20 can be adjusted. Simultaneously, the thread pitch and direction design ensure that the mounting shaft 41 moves only axially during vertical movement, avoiding lateral offset.

[0058] This embodiment achieves precise positioning and height adjustment of the mounting shaft 41 through the cooperation of internal and external threads. Its self-locking function can prevent the mounting shaft 41 from shifting due to gravity or liquid disturbance in the non-operating state, while simplifying the mechanical structure and improving operating accuracy and durability.

[0059] Furthermore, in this embodiment, the lid 5 includes a lid body 51 and a limiting sleeve 52. The lid body 51 has a mounting hole c extending vertically, the limiting sleeve 52 is installed in the mounting hole c, and the limiting hole b is formed on the limiting sleeve 52.

[0060] It is understood that the lid 5 is divided into two parts, including the main body 51 and the limiting sleeve 52. The lid 51 has a through mounting hole c in the center to accommodate the limiting sleeve 52; the limiting sleeve 52 is fixed in the mounting hole c by means of threads, snaps or plugs, and a limiting hole b is machined in the middle to allow the mounting shaft 41 to pass through.

[0061] On the one hand, the limiting sleeve 52 can be disassembled, facilitating maintenance such as replacing worn threaded parts. More importantly, since the lid 5 is generally made of plastic, and the mounting shaft 41 is threaded with the lid 5, to prevent wear on the threaded structure during adjustment of the lid 5 and the mounting shaft 41, the limiting sleeve 52 and the mounting shaft 41 can be made of high-strength and hard wear-resistant metal materials, depending on the actual situation, to ensure a precise fit between the limiting hole b and the mounting shaft 41.

[0062] Furthermore, in this embodiment, the kettle body 1 is provided with a first electrical contact part 71, which is used to connect to one pole of a power source; the lid 51 is provided with a second electrical contact part 72, which is used to conduct electricity with the first electrical contact part 71 when the lid 51 is placed on the kettle body 1; the limiting sleeve 52 and the mounting shaft 41 are made of conductive material, and the limiting sleeve 52 is conductively connected to the second electrical contact part 72.

[0063] The opening end of the kettle body 1 is provided with a first contact part 71, such as a metal contact or a conductive ring, for connecting one pole of an external power source, such as a positive or negative pole. The edge of the lid 51 is provided with a second contact part 72, such as a conductive sheet or a spring contact. When the lid 5 is closed, the second contact part 72 is in direct contact with the first contact part 71 or connected through a conductive path to form a power circuit.

[0064] The limiting sleeve 52 is installed in the mounting hole c of the cover 51. Both the limiting sleeve 52 and the mounting shaft 41 are made of conductive material. The upper end of the limiting sleeve 52 is in contact with the second electrical contact part 72 of the cover 51, and the lower end is connected to the mounting shaft 41 through the external and internal threads, so as to transmit current to the mounting shaft 41. The mounting shaft 41 further conducts the current to the second electrode part 20 connected to its lower end, thereby realizing a complete circuit path of one pole of the power supply through "first electrical contact part 71 → second electrical contact part 72 → limiting sleeve 52 → mounting shaft 41 → second electrode part 20".

[0065] This design, by making the limiting sleeve 52 and the mounting shaft 41 conductive materials and utilizing the electrical connection structure between the pot body 1 and the lid 51, achieves an integrated design of the power supply path for the electrode section. No additional wires are required; the mechanical structure itself is conductive, which simplifies the complexity of the circuit connection and ensures the reliability of current transmission.

[0066] Furthermore, in this embodiment, the side wall of the mounting shaft 41 is provided with a limiting protrusion; the inner wall of the limiting hole b is provided with a stop, the stop being located above the limiting protrusion, and used to stop the limiting protrusion when the mounting shaft 41 moves downward, so as to limit the mounting shaft 41 to the lower limit position.

[0067] The side wall of the mounting shaft 41 is provided with an annular limiting protrusion along the circumferential direction. Its height is slightly lower than the total length of the mounting shaft 41, and it is used to cooperate with the stop part of the limiting hole b.

[0068] The inner wall of the limiting hole b has a limiting stop, such as an annular boss or a groove, protruding near the top of the lid 5. The position is directly above the limiting protrusion of the mounting shaft 41. When the mounting shaft 41 moves downward to the limit position, the limiting protrusion contacts the stop and stops, preventing the mounting shaft 41 from moving downward too much.

[0069] When the user moves the mounting shaft 41 downwards, the limiting protrusion moves downwards synchronously with the mounting shaft 41 until it touches the stop in the limiting hole b. At this time, the mounting shaft 41 is locked at the lower limit position to avoid excessive interference between the electrode and the bottom plate 11 of the kettle body 1, which could cause a short circuit.

[0070] Specifically, please refer to Figure 6 In another specific embodiment, the mounting shaft 41 and the limiting hole b are clearance-fitted; the limiting structure 6 further includes a limiting member 63 installed on the lid 5, the limiting member 63 being disposed on the side of the mounting shaft 41 to abut against the side of the mounting shaft 41 to radially limit the mounting shaft 41.

[0071] It is understood that a small gap is reserved between the outer diameter of the mounting shaft 41 and the inner diameter of the limiting hole b, allowing the mounting shaft 41 to slide freely when moving up and down, while the limiting member 63 offsets the risk of radial wobble caused by the gap.

[0072] The limiting component 63 can be a ring spring, a rubber washer, or a bellows, etc., which is sleeved on the side of the mounting shaft 41. Its outer diameter is slightly larger than the inner diameter of the limiting hole b, or it can be fixed to the inner wall of the limiting hole b through a slot. When the mounting shaft 41 moves up and down, the limiting component 63 is deformed by pressure and continuously applies radial pressure to the mounting shaft 41, so that it always maintains close contact with the inner wall of the limiting hole b, thereby eliminating the radial clearance of the clearance fit, preventing the mounting shaft 41 from tilting or shifting, and ensuring its precise axial sliding.

[0073] Of course, the limiting member 63 can also be a side component of the mounting shaft 41, which is movable in the direction of approaching and away from the mounting shaft 41. When it is necessary to position the mounting shaft 41, the limiting member 63 can be brought close to the side of the mounting shaft 41, so that the mounting shaft 41 is clamped and limited between the inner wall of the limiting hole b and the limiting member 63.

[0074] By using the clearance fit between the mounting shaft 41 and the limiting hole b, combined with the radial limiting of the limiting component 63, the smooth up and down movement of the mounting shaft 41 is ensured, while eliminating the shaking problem caused by the clearance, so as to achieve stepless adjustment.

[0075] Specifically, please refer to Figure 7In another embodiment, the limiting structure 6 further includes a positioning part 64 and a plurality of mating parts 65 respectively disposed on one side of the limiting hole b and the mounting shaft 41. The plurality of mating parts 65 are spaced apart in the vertical direction. When the mounting shaft 41 moves up and down, the positioning part 64 can be positioned and mated with each of the mating parts 65.

[0076] The side wall of the mounting shaft 41 is provided with at least one positioning part 64, which can be configured as an annular boss or a snap fastener. The inner wall of the limiting hole b is provided with multiple mating parts 65 at intervals in the vertical direction. The mating parts 65 can be configured as grooves or holes that match the positioning parts 64. When the mounting shaft 41 moves up and down, the positioning part 64 can engage with the mating parts 65 at different heights, for example, by elastic deformation or mechanical snap fasteners, so that the mounting shaft 41 stops at one of a number of preset discrete height positions to correspond to different standard water level lines.

[0077] Specifically, please refer to Figure 8 In another embodiment, the adjustment structure 4 includes a telescopic shaft 42 that can be extended and retracted. The upper end of the telescopic shaft 42 is connected to the lid 5, and the lower end of the telescopic shaft 42 is connected to the second electrode part 20.

[0078] The upper end of the telescopic shaft 42 is fixedly connected to the lid 5, and the lower end is connected to the second electrode part 20, allowing the second electrode part 20 to move vertically as the telescopic shaft 42 is stretched or compressed. The telescopic shaft 42 can employ a multi-sleeve structure internally, or combine elastic components (such as springs) and limit buckles to achieve height adjustment while maintaining structural stability and reset capability. The user can manually pull or control the length of the telescopic shaft 42 through a drive device, thereby causing the second electrode part 20 to adapt to changes in the liquid level within the containment cavity, always maintaining its submerged state.

[0079] By using a retractable telescopic shaft 42 as an adjustment structure, the second electrode part 20 can move up and down flexibly according to the liquid height. It is simple to operate, has a sensitive response, and can effectively adapt to the electrode position requirements under different water volume conditions.

[0080] Specifically, in another embodiment, please refer to Figure 10 The liquid heating container 100 further includes a driving device 43, which has a driving part that is movably arranged in the vertical direction. The driving part is connected to the second electrode part 20 to drive the second electrode part 20 to move up and down.

[0081] The drive device 43 can be configured as an electric push rod, a linear actuator, or a motor-screw combination. The drive part at the output end of the drive device 43 is fixed to the second electrode part 20 via a connecting rod or direct connection, driving it to move in the up-down direction. The drive part can be a push rod or a slider, etc.

[0082] The drive device 43 is electrically connected to the electronic control device 3 and receives real-time data from the liquid level sensor. When a change in liquid level is detected, the electronic control device 3 calculates the optimal height of the second electrode section 20 using a preset algorithm and drives the motor or actuator of the drive device 43 to move, causing the drive unit to automatically raise and lower the second electrode section 20 to the target position, thereby achieving dynamic optimization of the electrode spacing.

[0083] By integrating the automated drive device 43, the second electrode section 20 can be precisely and steplessly adjusted without the need for manual operation by the user, which significantly improves the intelligence level and ease of operation of the equipment.

[0084] In another embodiment, please refer to Figure 9 The adjustment structure 4 further includes a rotating part 44 and a traction member 45. One end of the traction member 45 is connected to the rotating part 44 and is wound around the rotating part 44. The other end of the traction member 45 is connected to the second electrode part 20. The rotating part 44 is rotatably arranged around a rotation axis extending along a first horizontal direction, and is used to wind and unwind the traction member 45 so that the second electrode part 20 can move up and down.

[0085] The rotating part 44 is mounted on the lid 5 or the body of the kettle and rotates around a rotation axis in the first horizontal direction, for example, by a manual knob or electric drive. One end of the traction member 45 is wound and fixed to the rotating part 44, and the other end is connected to the second electrode part 20. When the rotating part 44 rotates in the forward or reverse direction, the traction member 45 can be wound or unwound, thereby driving the second electrode part 20 to move up and down.

[0086] Understandably, the traction component 45 can be made of materials such as flexible ropes, metal wires, or high-strength straps, which have good tensile strength and flexibility to ensure a smooth and reliable lifting process.

[0087] By setting an adjustment structure in which the rotating part 44 cooperates with the traction member 45, the user or control system can precisely control the height position of the second electrode part 20 through rotation, so that it can be flexibly adjusted with the liquid level, always maintaining the submerged state and maintaining the continuity of the electric field effect.

[0088] Understandably, for the kettle body 1, the bottom plate 11 is set as a flat surface, and at least a portion of the bottom plate 11 is made of a conductive material with good thermal conductivity, such as aluminum alloy or stainless steel. At least a portion of the bottom plate 11 is set as the first electrode portion 10, and the sidewall is made of an insulating material.

[0089] The first electrode portion 10 is formed on the base plate 11 and is integrated with the base plate 11. The first electrode portion 10 can be embedded or fixed to the surface of the base plate 11, or it can be a part of the base plate 11. This arrangement integrates the first electrode portion 10 with the base plate 11, rather than suspending it in the receiving cavity a, which facilitates cleaning the kettle body 1.

[0090] Specifically, since the first electrode part 10 and the second electrode part 20 need to withstand a certain chemical reaction when current passes through them, if the material is not corrosion resistant, it may cause corrosion on the electrode surface, thereby affecting the performance and life of the device. In this embodiment, the first electrode part 10 and the second electrode part 20 are made of titanium alloy, platinum alloy or carbon rod.

[0091] Titanium alloys have excellent corrosion resistance, biocompatibility and high strength, and can work stably for a long time in high temperature and electrolytic environments, avoiding the dissolution and contamination of liquids by electrode materials.

[0092] Platinum alloys, on the other hand, are more chemically inert and have better electrical conductivity, making them suitable for applications requiring high electric field strength or long-term stable electric fields.

[0093] Carbon rods offer high conductivity, cost advantages, and good corrosion resistance, making them suitable for routine extraction needs. Titanium alloys, platinum alloys, or carbon rods ensure the durability of the electrodes under heating and electric fields, while preventing the destruction of nutrients or the precipitation of harmful substances due to material reactions, thus guaranteeing the safety and efficiency of the extraction process.

[0094] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
