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 incorporates 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 in the food towards the positive electrode section and positive particles towards the negative electrode section, thereby accelerating the extraction of charged particles from the food and improving extraction efficiency. A further challenge of this design is ensuring that the microcurrent extraction module avoids unnecessary energy consumption when the lid is separated from the kettle body. Additionally, the design aims to quickly and reliably restore the microcurrent extraction function when the lid is reinstalled onto the kettle body.

[0005] The main purpose of this invention is to provide a liquid heating container that can improve safety, energy efficiency, and ease of use.

[0006] To achieve the above objectives, the liquid heating container proposed in this utility model includes:

[0007] The kettle body assembly includes a kettle body and a first electrode portion. The kettle body has a receiving cavity with an opening at the upper end, and a first contact portion electrically connected to the first electrode portion is provided on the kettle body.

[0008] A cover assembly includes a cover and a support member mounted on the cover. The support member is used to hold food ingredients, and at least part of the support member is configured as a second electrode portion, which is disposed opposite to a first electrode portion. The cover also has a second contact portion electrically connected to the second electrode portion. When the cover assembly is closed over the opening, the second contact portion can connect to the first contact portion.

[0009] An electronic control device is electrically connected to the first electrode section and the second contact section.

[0010] In one embodiment, the kettle body is provided with a first mounting portion, and the first mounting portion is provided with a first power receiving portion;

[0011] The cover is provided with a second mounting part, and the second mounting part is provided with a second power receiving part;

[0012] When the lid is placed on the open end of the pot body, the first electrical contact part and the second electrical contact part are connected and conduction is established.

[0013] In one embodiment, the first mounting portion and the second mounting portion are respectively provided with positioning grooves and positioning protrusions on their two end faces that are arranged opposite to each other;

[0014] The first electrical contact is installed in the positioning groove, and the second electrical contact is installed in the positioning protrusion.

[0015] In one embodiment, both the first and second electrical contacts are configured as plug terminals, one of which is configured as a female plug terminal and the other as a male plug terminal;

[0016] The liquid heating container further includes at least one conductive wire, through which the first electrode portion or the second electrode portion is connected to the corresponding plug-in terminal.

[0017] In one embodiment, the conductive line is provided with a switch for turning the conductive line on and off.

[0018] In one embodiment, the liquid heating container further includes a handle mounted on the body of the container, and the upper end of the handle is provided with the first electrical contact portion;

[0019] A conductive mounting part is provided on the inner side of the cover, and a second electrical receiving part is provided on the lower outer side of the cover, which is opposite to the first electrical receiving part. The conductive mounting part and the second electrical receiving part are electrically connected.

[0020] The second electrode portion is detachably mounted on the conductive mounting portion.

[0021] In one embodiment, the carrier includes a filter screen that extends from the opening into the receiving cavity, and the second electrode portion is disposed on the filter screen.

[0022] In one embodiment, the liquid heating container further includes a base plate, at least a portion of which is made of a conductive material;

[0023] The liquid heating container further includes a heating assembly connected to the base plate for heating the liquid in the containment cavity, and at least a portion of the base plate is the first electrode portion.

[0024] In one embodiment, the distance between the first electrode portion and the second electrode portion is D, where 10mm ≤ D ≤ 100mm.

[0025] In one embodiment, the first electrode portion and the second electrode portion are made of titanium alloy, platinum alloy or carbon rod.

[0026] In one embodiment, the liquid heating container includes an electric kettle or a health-preserving kettle.

[0027] In this invention, the pot body is equipped with a first electrode and a second electrode. Through the action of an electric field and electrostatic attraction, the first and second electrodes effectively adsorb positive and negative particles of the food in the liquid, enhancing the solubility of the food or releasing nutrients. Before extraction, the food is placed in a carrier, and then the lid assembly is placed over the pot opening. The second electrode contacts the first electrode, and the electronic control device detects the connection and starts supplying power, initiating the microcurrent extraction process. After extraction, the user can easily remove the lid assembly for cleaning or replacing the food. During this process, because the first and second electrodes are separated, the electronic control device automatically cuts off power, improving safety and convenience, thus providing a liquid heating container that enhances safety, energy efficiency, and ease of use.

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0047] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0048] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0049] Two electrode sections (positive and negative electrodes) connected to the electronic control device are spaced apart in the kettle to accelerate the movement of negative particles in the food towards the positive electrode section and positive particles towards the negative electrode section, thereby accelerating the precipitation of charged particles in the food and improving extraction efficiency. How to ensure that the microcurrent extraction module avoids unnecessary energy consumption when the lid of the kettle is separated from the kettle body; and how to quickly and reliably restore the microcurrent extraction function when the lid is reinstalled on the kettle body are further problems faced by this design.

[0050] This utility model proposes a liquid heating container 100, which aims to provide a liquid heating container that can improve safety, energy saving effect and ease of use.

[0051] Please see Figures 1 to 3 In one embodiment of this utility model, the liquid heating container 100 includes a pot body assembly 1, a lid assembly 2, and an electronic control device 3. The pot body assembly 1 includes a pot body 11 and a first electrode portion 10. The pot body 11 has a receiving cavity a with an opening at the upper end. A first contact portion 12 electrically connected to the first electrode portion 10 is provided on the pot body 11. The lid assembly 2 includes a lid 21 and a support member 22 installed on the lid 21. The support member 22 is used to hold food, and the support member 22 is at least partially configured as a second electrode portion 20. The second electrode portion 20 is arranged opposite to the first electrode portion 10. A second contact portion 23 electrically connected to the second electrode portion 20 is also provided on the lid 21. When the lid assembly 2 is closed on the opening, the second contact portion 23 can be connected to the first contact portion 12. The electronic control device 3 is electrically connected to the first electrode portion 10 and the second contact portion 23.

[0052] 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.

[0053] The upper end of the pot body 11 is open to form a receiving cavity a for holding liquids and ingredients to be heated or extracted.

[0054] The first electrode portion 10 is located inside or at the bottom of the vessel body 11 and is electrically connected to the electronic control device 3, serving as one electrode in the extraction process. The first electrode portion 10 may be a part made of a metal sheet or other conductive material integrated onto the bottom plate 13 of the vessel body 11.

[0055] The first contact portion 12 is disposed at an appropriate position on the kettle body 11 (e.g., near the top edge) and is electrically connected to the first electrode portion 10. The function of the first contact portion 12 is to establish an electrical connection with the second contact portion 23 when the lid assembly 2 is placed over the opening of the kettle body 11.

[0056] The lid 21 covers the opening of the pot body 11, ensuring a tight seal and safety during use. The support member 22 is installed below the lid 21 and is used to support the food. At least a portion of the support member 22 is configured as the second electrode 20 so that it works opposite to the first electrode 10 during the extraction process.

[0057] The carrier 22 can be designed into different shapes and sizes according to actual needs, such as filters, baskets, etc., to adapt to the extraction needs of different types of ingredients.

[0058] The second electrode 20 serves as the other electrode in the extraction process, cooperating with the first electrode 10. The second electrode 20 may be made of magnetic material or other materials with good electrical conductivity.

[0059] The second electrical contact 23 is disposed on the cover 21 and electrically connected to the second electrode 20. When the cover assembly 2 is placed over the opening of the pot body 11, the second electrical contact 23 can accurately connect with the first electrical contact 12, thereby enabling the electronic control device 3 to supply power to the two electrode parts.

[0060] The electronic control device 3 is electrically connected to the first electrode 10 and the second contact 23, and is responsible for controlling the current supply throughout the extraction process. The electronic control device 3 adjusts the output current magnitude and duration according to a preset program or user input to optimize the extraction effect of nutrients.

[0061] It should also be noted that since the nutrients in food are charged particles, during the microcurrent extraction process, these charged particles will be released due to the electric field force and the increased permeability of the cell membrane itself. In other words, positively charged particles move towards the negative electrode, and negatively charged particles move towards the positive electrode.

[0062] When the electronic control device 3 is powered on, current flows through the two electrode sections, creating an electric field in the liquid within the receiving cavity a. The presence of this electric field exerts a force on surrounding charged particles (such as ions). If the first electrode section 10 carries a positive charge (or is made positively charged by current), it attracts nearby negatively charged particles. If the second electrode section 20 carries a negative charge (or is made negatively charged by current), it attracts nearby positively charged particles. Positive particles in the food move towards the cathode, and negative particles move towards the anode.

[0063] When the lid assembly 2 is removed from the pot body 11, the first power contact 12 and the second power contact 23 separate, automatically cutting off the power supply to ensure safety and avoid energy waste; when the lid 21 is put back in place, the two come into contact again, restoring the power supply and immediately restoring the microcurrent extraction function.

[0064] In this invention, the pot body 11 is provided with a first electrode 10 and a second electrode 20. The first electrode 10 and the second electrode 20, through the action of an electric field and electrostatic attraction, can effectively adsorb positive and negative particles of the food in the liquid, enhancing the solubility of the food in the liquid or releasing nutrients. Before extraction, the food is placed in the carrier 22, and then the lid assembly 2 is placed over the opening of the pot body 11. The second contact part 23 contacts the first contact part 12. Upon detecting the connection, the electronic control device 3 starts supplying power, initiating the microcurrent extraction process. After extraction, the user can easily remove the lid assembly 2 for cleaning or replacing the food. During this process, because the first contact part 12 separates from the second contact part 23, the electronic control device 3 automatically cuts off the power, improving safety and convenience. This provides a liquid heating container 100 that enhances safety, energy efficiency, and ease of use.

[0065] 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 11. Figures 7 to 14 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 7 and Figure 8 Let's take an example to illustrate:

[0066] Figure 7 These are the microcurrent values ​​detected by existing technology for hibiscus flowers in liquid at different times. Figure 8These 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.

[0067] according to Figure 7 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.

[0068] according to Figure 8 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 430uA; 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.

[0069] 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.

[0070] For details, please continue reading Figures 1 to 3 In one embodiment, the kettle body 11 is provided with a first mounting part 41, and the first mounting part 41 is provided with a first electrical contact part 12; the lid body 21 is provided with a second mounting part 42, and the second mounting part 42 is provided with a second electrical contact part 23; when the lid body 21 is placed on the open end of the kettle body 11, the first electrical contact part 12 and the second electrical contact part 23 are connected and conductive.

[0071] It is understood that the first mounting part 41 is located in a specific area of ​​the kettle body 11 near the opening, and is used for mounting the first electrical connection part 12. The first mounting part 41 may be part of the kettle body 11 or a separate additional component.

[0072] The position and shape of the first mounting part 41 should facilitate alignment with the second mounting part 42 on the cover 21, and ensure good mechanical stability and electrical contact.

[0073] The first contact portion 12 is integrated within the first mounting portion 41 and serves as one of the electrical connection points, electrically connected to the first electrode portion 10, and further connected to the electronic control device 3. The first contact portion 12 may employ a metal sheet, spring contact, or other forms of conductive element to ensure a reliable electrical connection.

[0074] The second mounting part 42 is located below the lid 21 near the edge and is used for mounting the second electrical connection part 23. The position of the second mounting part 42 must precisely correspond to the first mounting part 41 on the pot body 11 so that the lid 21 can be accurately aligned when it is placed over the opening of the pot body 11.

[0075] It should be noted that the second mounting part 42 can be designed with a certain degree of flexibility to compensate for manufacturing tolerances and ensure good electrical contact.

[0076] The second electrical contact 23 is integrated within the second mounting portion 42 and serves as a second electrical connection point, electrically connected to the second electrode portion 20. The second electrical contact 23 matches the first electrical contact 12 to ensure a stable electrical connection between them.

[0077] When the lid 21 is placed over the open end of the pot body 11, the first mounting part 41 and the second mounting part 42 are aligned, so that the first electrical contact part 12 and the second electrical contact part 23 are precisely connected and conductive. This arrangement not only ensures the reliability of the electrical connection, but also improves the convenience of use.

[0078] In addition, to enhance the stability of electrical contact, elastic materials (such as spring contacts) or surface plating (such as gold plating) can be added to the contact surfaces of the first contact part 12 and the second contact part 23 to reduce contact resistance and improve conductivity.

[0079] Further, please refer to Figure 2 and Figure 3 In this embodiment, the first mounting part 41 and the second mounting part 42 are respectively provided with positioning groove b and positioning protrusion 421 on their two end faces that are arranged opposite to each other; the first power receiving part 12 is installed in the positioning groove b, and the second power receiving part 23 is installed in the positioning protrusion 421.

[0080] The first mounting part 41 includes the positioning groove b, which not only serves a mechanical positioning function but also provides an installation position for the first electrical connection part 12. It should be noted that the positioning groove b needs to consider accuracy and stability to ensure accurate alignment with the positioning protrusion 421 on the second mounting part 42 when the cover assembly 2 is installed.

[0081] The second mounting portion 42 includes the positioning protrusion 421, which not only serves a mechanical positioning function but also provides a mounting position for the second electrical connection portion 23. It should be noted that the positioning protrusion 421 matches the positioning groove b on the first mounting portion 41 to ensure a stable mechanical and electrical connection between them.

[0082] When the cover 21 is placed on the open end of the pot body 11, the positioning protrusion 421 on the second mounting part 42 inserts into the positioning groove b of the first mounting part 41, so that the first electrical contact part 12 and the second electrical contact part 23 are precisely connected and conductive. By providing the positioning groove b and the positioning protrusion 421 on the first mounting part 41 and the second mounting part 42 respectively, not only can efficient and accurate mechanical alignment be achieved, but also the reliability and stability of the electrical connection can be ensured.

[0083] Specifically, to provide more diverse connection options and simplify the external structure of the liquid heating container 100, please refer to [link / reference needed]. Figure 4 and Figure 5 In another embodiment, both the first electrical contact 12 and the second electrical contact 23 are configured as plug terminals, one of which is configured as a female plug terminal and the other as a male plug terminal; the liquid heating container 100 further includes at least one conductive wire 5, and the first electrode part 10 or the second electrode part 20 is connected to the corresponding plug terminal through the conductive wire 5.

[0084] The first electrical connection part 12 and the second electrical connection part 23 are respectively configured as male and female plug terminals to ensure that when the cover assembly 2 is placed on the opening end of the pot body 11, the two can quickly and accurately connect and conduct electricity.

[0085] The connectors need to be designed to prevent incorrect or reverse insertion. This can be achieved, for example, through an asymmetrical shape design.

[0086] To enhance the stability of electrical contact, spring contacts or other elastic materials can be added inside the plug terminals to reduce contact resistance and improve conductivity.

[0087] The liquid heating container 100 further includes at least one conductive wire 5 for connecting the first electrode portion 10 and the second electrode portion 20 to the corresponding first contact portion 12 and second contact portion 23, respectively.

[0088] The selection of the conductive wire 5 should take into account its high temperature resistance, corrosion resistance, and other properties to ensure reliability under long-term use. Commonly used materials include copper wire with an outer insulating layer.

[0089] Before extraction, the ingredients are placed in the carrier 22, and then the lid assembly 2 is placed over the opening of the pot body 11. At this time, the two ends of the conductive wire 5 are precisely connected to the male and female connectors respectively, and the electronic control device 3 detects the connection and starts supplying power to initiate the microcurrent extraction process.

[0090] After extraction, the user can easily unplug both ends of the conductive wire 5 and remove the cover assembly 2 for cleaning or replacing ingredients. In this way, there is no need to form a specific structure on the cover 21 to facilitate the connection of the two electrical contacts. The positions of the two electrical contacts can be flexibly set as needed, and the conductive wire 5 provides flexibility for connecting the circuit.

[0091] Please see Figure 6 In another embodiment, the conductive wire 5 is provided with a switch 6 for turning the conductive wire 5 on and off.

[0092] The switch 6 is installed on the conductive wire 5 for manually controlling the connection and disconnection of the conductive wire 5. The switch 6 can be a mechanical push-button switch 6, a slide switch 6, or other types of switch 6, depending on the requirements of the actual application scenario.

[0093] By installing the switch 6 on the conductive line 5, users can manually control the connection and disconnection of the electrical connection as needed, greatly improving the flexibility and safety of use.

[0094] Please see Figure 1 and Figure 2 In this embodiment, the liquid heating container 100 further includes a handle 7 installed outside the pot body 11, the upper end of the handle 7 is provided with the first electrical contact part 12; the inner side of the cover 21 is provided with a conductive mounting part 24, the lower outer side of the cover 21 is provided with a second electrical contact part 23 opposite to the first electrical contact part 12, the conductive mounting part 24 is electrically connected to the second electrical contact part 23; the second electrode part 20 is detachably installed on the conductive mounting part 24.

[0095] The handle 7 is installed on the outside of the pot body 11, making it easy for the user to hold and move the container. The handle 7 not only provides physical support, but also integrates the first electrical contact part 12 at its upper end.

[0096] The first electrical contact 12 is located at the upper end of the handle 7, ensuring precise connection and conductivity with the second electrical contact 23 when the lid assembly 2 is placed over the opening of the kettle body 11. The first electrical contact 12 can be securely mounted on the handle 7 by welding or other fixing methods, and is electrically connected to the first electrode part 10 through internal wiring. For example, a wiring channel is formed inside the handle 7, and the lower end of the handle 7 communicates with the base of the electronic control device 3 installed at the bottom of the kettle body 11. The connecting wire can be run through the handle 7, with its upper end connected to the first electrical contact 12 and its lower end connected to the electronic control device 3.

[0097] The conductive mounting portion 24 is located inside the cover 21 and is used to support and fix the second electrode portion 20. The conductive mounting portion 24 must have good conductivity to ensure the reliability of the electrical connection.

[0098] The conductive mounting part 24 can adopt a snap-fit, thread or other form of fixing mechanism, so that the second electrode part 20 can be easily disassembled and installed.

[0099] Thus, the conductive mounting part 24 serves as the mounting point for the second electrode part 20, and the conductive mounting part 24 also functions as part of the circuit connection, simplifying the structure.

[0100] Please see Figure 1 , Figure 2 and Figure 4 In one embodiment, the carrier 22 includes a filter screen that extends from the opening into the receiving cavity a, and the second electrode portion 20 is disposed on the filter screen.

[0101] The filter screen, as part of the support member 22, extends downward from the opening of the cover 21 into the receiving cavity a of the pot body 11. The filter screen is made of food-grade materials, such as stainless steel or food-grade plastic, to ensure that it is harmless to the human body and corrosion-resistant.

[0102] It should be noted that the filter screen needs to balance filtration efficiency and water flow. Typically, the filter screen is designed with a mesh structure with appropriate pore size to effectively block large particles while allowing the liquid to flow freely.

[0103] The second electrode portion 20 is directly integrated into the filter screen, thus achieving an effective distribution of the electric field without adding extra complexity. The second electrode portion 20 can be part of the filter screen, or it can be fixed to the filter screen by other means (such as welding or crimping).

[0104] In this embodiment, please refer to Figure 1 The liquid heating container 100 also includes a base plate 13, at least a portion of which is made of a conductive material; the liquid heating container 100 also includes a heating component 8, which is connected to the base plate 13 and is used to heat the liquid in the receiving cavity a, and at least a portion of the base plate 13 is the first electrode part 10.

[0105] With this configuration, the base plate 13 is heated by the heating component 8. In addition to transferring the heat from the heating component 8, the base plate 13 also has the function of heating the liquid inside the pot body 11 and serves as an electrode for extraction.

[0106] Please see Figure 4 In one embodiment, the distance between the first electrode portion 10 and the second electrode portion 20 is D, where 10mm ≤ D ≤ 100mm.

[0107] The distance between the first electrode portion 10 and the second electrode portion 20 is defined as D, and its range is set from 10 mm to 100 mm. Setting D within this range can better balance the relationship between electric field strength and current distribution uniformity, ensuring the best extraction effect.

[0108] If the spacing is too small (less than 10 mm), it may lead to excessive local current density, causing excessive corrosion or electrolysis on the electrode surface; if the spacing is too large (greater than 100 mm), it may weaken the electric field strength and reduce the extraction efficiency.

[0109] Therefore, a reasonable spacing range helps maintain a stable current density and a uniform electric field distribution, thereby improving the extraction efficiency of nutrients.

[0110] Furthermore, it should be noted that the liquid heating container 100 is equipped with a minimum water level mark to indicate the minimum amount of water required for normal operation of the liquid heating container 100. This water level mark not only ensures the safe operation of the liquid heating container 100, but also ensures that both the first electrode section 10 and the second electrode section 20 can be completely submerged in water.

[0111] The electrode spacing D can be adjusted according to the lowest water level to ensure that both electrodes are fully submerged in water even under the lowest water level conditions. This design not only ensures the effectiveness and safety of the electrical connection but also avoids adverse consequences (such as dry burning or short circuits) caused by partial electrode exposure to air.

[0112] For example, assuming the height corresponding to the lowest water level is H, when selecting the electrode spacing D, it must be ensured that D is less than or equal to H so that under the lowest water level conditions, both the first electrode part 10 and the second electrode part 20 can be covered by water.

[0113] It should also be noted that the height H corresponding to the lowest water level line can be specifically set according to the shape and size of the vessel body 11. If the liquid heating container 100 is short and stout, the lowest water level line is set lower; if the liquid heating container 100 is tall and slender, the lowest water level line is set higher.

[0114] Specifically, since the first electrode portion 10 and the second electrode portion 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 lifespan of the device. In this embodiment, the material of the first electrode portion 10 and the second electrode portion 20 is set to a corrosion-resistant material.

[0115] It should be noted that corrosion-resistant materials refer to materials that can resist chemical corrosion and physical wear. These materials typically possess good chemical stability and are not easily damaged even in harsh environments (such as humid, high-temperature, acidic or alkaline media). Corrosion-resistant materials include stainless steel, titanium alloys, nickel alloys, and certain coating materials (such as polymer coatings), etc.

[0116] In this embodiment, the first electrode portion 10 and the second electrode portion 20 are made of titanium alloy, platinum alloy or carbon rod.

[0117] Titanium alloys possess excellent corrosion resistance, especially in acidic and salt water environments, resulting in a long service life for titanium alloy electrodes during electrochemical reactions. Furthermore, titanium alloys exhibit high strength and low density, making them both lightweight and robust, suitable for applications requiring weight reduction.

[0118] Platinum alloys possess excellent electrical conductivity, enabling efficient current transfer and ensuring the formation and maintenance of an electrostatic field. Simultaneously, platinum alloys can withstand high-temperature environments, making them suitable for operations requiring heating, such as the heating component 8 in this design. Furthermore, platinum alloys are chemically very stable, rarely reacting with other substances, thus avoiding contamination and changes in taste, and guaranteeing the quality of the extraction process.

[0119] Carbon rods possess excellent electrical conductivity, making them effective as electrodes, especially maintaining stable current transmission under low voltage conditions. Compared to precious metal alloys, carbon rods are less expensive and easier to process into various shapes, making them suitable for mass production and customized designs. They are also free of heavy metals, meeting the requirements of modern green manufacturing.

[0120] Therefore, titanium alloys, platinum alloys, and carbon rods can all conduct current well, but they do not carry any charge themselves. Thus, they will not interfere with the electrostatic field formed by the first electrode part 10 and the second electrode part 20, ensuring the effectiveness and stability of the nutrient extraction process.

[0121] 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.
