[0027] Based on this, the present invention provides an electrically heated container, as shown in the following embodiment. Figure 1 , Figure 1 This is a schematic diagram of the basic structure of the electric heating container of this utility model.

[0028] In this embodiment, the electric heating container includes a kettle body 10, a power supply device 20, a first electrode part 30, and a second electrode part 40; The vessel body 10 is used to hold liquid, and a low-pressure insulation layer is provided on the outer wall of the vessel body 10; The first electrode portion 30 and the second electrode portion 40 are both disposed in the internal space of the pot body 10, and there is a gap between the first electrode portion 30 and the second electrode portion 40; The power supply device 20 includes a voltage output terminal and a ground terminal. The voltage output terminal is connected to the first electrode plate, and the ground terminal is connected to the second electrode plate. The power supply device 20 is used to create a pressure difference between the first electrode plate and the second electrode plate to electrolyze the liquid in the vessel 10.

[0029] It should be noted that in this embodiment, the electric heating container can be an electric kettle, a health pot, a food processor, a soy milk maker, etc. Although these different types of electric heating containers differ in appearance and functional focus, they can all include the core structure and working principle described in this embodiment. The electric heating container includes a kettle body 10, a power supply device 20, a first electrode part 30, and a second electrode part 40. The kettle body 10 is used to hold a conductive liquid, which can be simple water or a mixed liquid containing various solid ingredients. For example, when making health drinks, the kettle body may contain water with added ingredients such as red dates and goji berries. The exterior of the kettle body 10 is provided with a low-voltage insulation layer, which can insulate against a voltage of at least 1.2V. During daily use, even if there is a slight leakage inside the electric heating container, this insulation layer can effectively prevent current from being conducted to the outside of the kettle body, thus avoiding the risk of electric shock to the user due to contact with the leaking part, providing strong protection for the user's personal safety. The first electrode portion 30 and the second electrode portion 40 are both located within the internal space of the kettle body 10, and there is a gap between them. Both the first electrode portion 30 and the second electrode portion 40 are made of conductive material, and their shapes are not further limited; they can be plates. The power supply device 20, which may be of a certain type or other shape, includes a voltage output terminal and a ground terminal. The voltage output terminal is connected to the first electrode 30, and the ground terminal is connected to the second electrode 40. When liquid is present in the electric heating container, and the liquid fills the gap between the first electrode 30 and the second electrode 40, and the power supply device 20 is started, the first electrode 30 is energized. The first electrode 30 and the second electrode 40 are connected through the liquid in the electric heating container. Due to the pressure difference between the first electrode 30 and the second electrode 40, the liquid in the electric heating container can be electrolyzed, thereby promoting the dissolution of substances in the liquid and making the nutrients in the liquid better absorbed.

[0030] In this embodiment, when heating a liquid using an electric heating container, the power supply device 20 is energized, causing the first electrode 30 in the electric heating container to become energized. The first electrode 30 and the second electrode 40 are connected by the liquid in the gap, forming a pressure difference to electrolyze the liquid in the electric heating container. This allows the electric heating container to perform the basic function of heating liquid while also having the function of electrolysis, providing users with a more diversified and efficient user experience.

[0031] In some embodiments, the first electrode portion 30 and the second electrode portion 40 are plate-shaped. The first electrode portion 30 is disposed on the upper part of the inside of the pot body near the spout, and the second electrode portion 40 is disposed on the bottom part of the inside of the pot body, so that the gap between the first electrode portion 30 and the second electrode portion 40 is maximized, thereby improving the efficiency of electrolysis.

[0032] In another feasible embodiment, the bottom of the pot body 10 includes a base plate, at least a portion of which is a first electrode portion 30, and a second electrode portion 40 extends upward from the base plate. That is, both the first electrode portion 30 and the second electrode portion 40 are located at the lower end of the pot body 10. Even when the liquid level is low, the first electrode portion 30 and the second electrode portion 40 can be ensured to always be immersed in the liquid, maintaining an effective electric field effect, ensuring that the extraction efficiency of nutrients is not affected, and releasing nutrients for as long as possible. Users do not need to worry about insufficient extraction due to insufficient water.

[0033] In other embodiments, the first electrode portion 30 is annular and located around the lower end of the second electrode portion 40, surrounding the bottom of the second electrode portion 40 and situated outside it. The second electrode portion 40 extends upward from the base plate 2, forming a columnar or rod-shaped structure perpendicular to the base plate 2.

[0034] Thus, the annular arrangement of the first electrode portion 30 not only increases the contact area between the first electrode portion 30 and the liquid, allowing more liquid molecules to participate in the electric field, but also provides a more uniform electric field distribution. Since the first electrode portion 30 surrounds the second electrode portion 40, it ensures a more uniform distribution of the electric field in the liquid, thereby improving the efficiency of particle movement and the extraction effect of nutrients.

[0035] In other embodiments, the first electrode portion 30 is arranged in the form of a disk.

[0036] The first electrode part 30 is configured as a planar circular structure with a large horizontal surface area and a large contact area, which allows the current to diffuse more evenly into the surrounding liquid, thereby improving the efficiency of particle movement and the extraction effect of nutrients.

[0037] In addition, the first electrode part 30 is set as a disk, which can also avoid the formation of sharp parts in the structure and avoid the formation of areas with high current density in sharp areas, which would intensify the exchange between particles and electrons and make the corrosion rate higher.

[0038] Furthermore, in one feasible implementation, please refer to Figure 2 The electric heating container also includes a handle 50; The handle 50 is connected to the kettle body 10, and a wire passes through the handle 50; The voltage output terminal of the power supply device 20 is connected to the first electrode part 30 via a wire in the handle 50.

[0039] In this embodiment, the handle 50 is located on the outside of the pot body 10 and connected to the pot body 10. A wire can pass through the handle 50. The voltage output terminal of the power supply device 20 is connected to the first electrode part 30 through the wire in the handle 50. This allows the first electrode part 30 to be located inside the upper part of the pot body 10, forming a larger gap between it and the second electrode part 40. This makes the distribution of the power in the liquid more gradual, avoids the risk of overheating caused by local current concentration, and can also increase the efficiency of power supply.

[0040] Specifically, in an electrically heated container with a handle 50, in order to bring the first electrode 30 closer to the spout, wires can be routed through the handle 50, with one end of the wire connected to the power supply 20 from the lower end of the handle 50 and the other end connected to the first electrode 30 from the upper end of the handle 50. This avoids messy internal wiring and also avoids the cost problem that may be increased by needing to route wires between the inner and outer walls of the side of the container.

[0041] Furthermore, in one feasible implementation, please refer to Figure 2 The electric heating container also includes a filter 60, which is placed in the internal space of the pot body 10, and the voltage output terminal of the power supply device 20 is connected to the filter 60 so that the filter 60 acts as the first electrode part 30.

[0042] It should be noted that in this embodiment, the filter 60 is made of conductive material and can be connected to the output terminal of the power supply device 20 as the first electrode part 30. The filter 60 can be a metal filter screen. Metal has good conductivity, which can ensure that the current passes through smoothly, thereby ensuring the stable operation of the entire circuit system. Moreover, the design of the filter screen structure not only meets the basic requirements of filtration and can effectively intercept impurities in the liquid, but also gives full play to its conductivity advantage during the electrolysis process.

[0043] In this embodiment, the filter 60 is connected to the voltage output terminal of the power supply device 20. After the power supply device 20 is started, the first electrode 30 forms a circuit with the second electrode 40 through the liquid in the electric heating container to electrolyze the liquid. Compared with other forms of first electrode 30, the filter 60 is usually designed as a filter screen structure, with its surface covered with many small mesh holes. These mesh holes greatly increase its contact area with the liquid. The larger contact area between the filter 60 and the liquid can improve the efficiency of electrolysis. In addition, the filter 60 usually has a certain length and extends inside the container. In actual use, when the liquid in the container is small, ordinary electrodes may not be able to make sufficient contact with the liquid, thus failing to use the electrolysis function normally. However, due to its extended length, the filter 60 can still contact the liquid even when the liquid volume is small, thus ensuring that the electrolysis function can still be used normally. In this way, no matter how much liquid is in the container, the filter 60 can effectively electrolyze the liquid, greatly improving the applicability and practicality of the electric heating container. It can meet the user's electrolysis needs whether a large amount of liquid needs to be electrolyzed or a small amount of liquid is required.

[0044] Furthermore, in one feasible implementation, please refer to Figure 2 The pot body 10 includes a pot body 11 and a pot lid 12, and the pot lid 12 is provided with a low-pressure insulation layer on the outside.

[0045] It should be noted that, in this embodiment, the low-voltage insulation layer needs to be able to block at least 1.2V of voltage.

[0046] In this embodiment, the kettle body 10 includes a kettle body 11 and a kettle lid 12. The kettle body 11 is mainly used to contain liquid, while the kettle lid 12 serves to seal the kettle body, prevent liquid from splashing out, and facilitate pouring. During the electrolysis process, a complex electric field and current distribution will be formed inside the electric heating container. Due to its position and material, the kettle lid 12 may come into contact with the liquid in the kettle, which may lead to leakage. To avoid the risk of electric shock caused by this leakage, a low-voltage insulation layer is provided on the outside of the kettle lid 12. When the electric heating container is in operation, even if the kettle lid 12 accidentally comes into contact with the liquid in the kettle, it can prevent the current from being transmitted to the user's body through the kettle lid 12, thus avoiding the risk of electric shock.

[0047] For example, when electrolyzing some liquids with a certain degree of conductivity, the ions in the liquid will move under the influence of the electric field, which may form a weak current on the surface of the lid 12. Without the protection of the low-voltage insulation layer, the user may feel an electric shock when touching the lid 12. With this low-voltage insulation layer, the risk of electric shock can be greatly reduced, providing the user with a safer and more reliable operating environment. At the same time, this insulation layer also has a certain degree of wear resistance and corrosion resistance, which can maintain the stability of its insulation performance during long-term use, ensuring that the safety of the electric heating container is always guaranteed.

[0048] In some feasible embodiments, the lid 12 includes a mounting portion, on which the second electrode portion 40 is detachably mounted. The second electrode portion 40 extends from the lid 12 into the interior of the pot body and is disposed opposite to the first electrode portion 30.

[0049] Furthermore, in one feasible embodiment, the power supply device 20 is embedded between the outer wall and the inner wall of the kettle body 10, and the kettle body 10 is provided with a power interface. The input end of the power supply device 20 is connected to the mains power or an AC generator through the power interface.

[0050] In this embodiment, the power supply device 20 can be embedded between the outer and inner walls of the kettle body 10 in the integrated electric heating container. This embedding method makes full use of the structural space of the kettle body 10, making the entire electric heating container more concise and compact in appearance. Specifically, the setting position of the power supply device 20 is not fixed, but has multiple options. The power supply device 20 can be set at the bottom, and the relatively concealed position at the bottom also helps to protect the power supply device 20 from external collisions and interference. It can also be set on the side. For some electric heating containers with special requirements for spatial layout or limited bottom space, this side setting method can better adapt to different design needs, and also facilitates reasonable layout and connection with other components. The kettle body 10 is provided with a power interface. The input end of the power supply device 20 is connected to the mains power or an AC generator through the power interface to supply power to the power supply device 20. From the perspective of structural design, the integrated setting greatly reduces the use of connecting parts. Integrating the power supply device 20 into the container can reduce connecting parts, reduce costs, and eliminate the need for connecting parts such as couplers 80, resulting in no contact resistance and less energy loss.

[0051] In another feasible implementation, please refer to Figure 2 The electric heating container also includes a base 70; The base 70 is connected to the kettle body 10 via a coupler 80; The power supply unit 20 is disposed in the base 70 and is connected to the first electrode part 30 and the second electrode part 40 via the coupler 80.

[0052] In this embodiment, the electric heating container can be a split type, and also includes a base 70. The base 70 is connected to the kettle body 10 through a coupler 80. The power supply device 20 is disposed in the base 70 and is connected to the first electrode part 30 and the second electrode part 40 through the coupler 80. From a mechanical connection point of view, the coupler 80 can ensure that the kettle body 10 is placed stably on the base 70, preventing the kettle body 10 from shaking or tipping over during use. From an electrical connection point of view, the coupler 80 is used for power transmission. It can safely and stably transmit the electrical energy in the base 70 to the kettle body 10. Placing the power supply device 20 in the base 70 can effectively protect the power supply device 20 from the influence of the external environment, such as preventing water splashes and dust from entering, thereby improving the service life and reliability of the power supply device 20. When the kettle body 10 needs to be cleaned, the user only needs to remove the kettle body 10 from the base 70 without worrying about the power supply device 20 being corroded by water.

[0053] Furthermore, in one feasible implementation, please refer to Figure 3 The coupler 80 is disposed at the bottom of the base 70 or the body 10, and the coupler 80 includes: NTC signal line 81 connects the NTC signal output terminal of power supply device 20 and the control chip of power supply device 20. Neutral wire 82 is used to provide a current loop for power supply device 20; Live wire 83 is used to supply power to power supply device 20; The micro power signal line 84 is used to control the output and shutdown of the power supply device 20 according to the control signal of the control chip. Ground wire 85, connected to the grounding terminal, is used for grounding.

[0054] It should be noted that, in this embodiment, the NTC signal line 81 is the signal line in the power supply device 20 that detects the resistance change of the negative temperature coefficient thermistor NTC. The negative temperature coefficient thermistor NTC is a type of sensor resistor whose resistance decreases as the temperature increases. In the electric heating container, by detecting the resistance change of the NTC in real time through the NTC signal line 81, the internal temperature change of the electric heating container can be accurately grasped. Once abnormal temperature fluctuations occur, the power supply device 20 can adjust its working state in a timely manner according to these changes, thereby ensuring that the electric heating container is always in a safe and stable operating environment.

[0055] In this embodiment, when the electric heating container is a split type, the coupler 80 is located at the bottom of the base 70 or the body 10. The coupler 80 includes an NTC signal line 81, which is used to detect the resistance change of the NTC in the power supply device 20 and transmit it to the control chip. The neutral wire 82 and the live wire 83 of the coupler 80 form a complete circuit in the power supply device 20. The micro power signal line 84 is used to control the output and shutdown of the power supply device 20 according to the control signal in the control chip. When the control chip determines that the power output needs to be adjusted based on the information fed back by various sensors, it will send corresponding control commands to the power supply device 20 through the micro power signal line 84. The power supply device 20 then accurately controls the on / off state of the output terminal according to these commands to achieve precise control of the electrolysis function. The ground wire 85 is connected to the grounding terminal for grounding. Grounding can effectively prevent leakage. When an accidental leakage occurs inside the electric heating container, the current will be conducted to the ground through the ground wire 85, thereby preventing electric shock to the user and ensuring the user's personal safety.

[0056] When the electric heating container is powered by the base 70, the kettle body 10 can be removed separately for cleaning without plugging or unplugging the power cord, making it more convenient to use.

[0057] Furthermore, in one feasible implementation, please refer to Figure 4 , Figure 4 This is a schematic diagram of the power supply device 20. The power supply device 20 also includes an input terminal and a first step-down module 21 and a second step-down module 22. The input side is connected to the mains power or an AC generator via the first step-down module 21; The other side of the input terminal is connected to the voltage output terminal through the second step-down module 22, which is used to step down the mains power to a preset safe voltage.

[0058] In this embodiment, the input terminal of the power supply device 20 is connected to the mains power or an AC generator via the first step-down module 21. The voltage output by the mains power or AC generator is usually too high to be directly used to power the internal circuitry of the power supply device 20. The first step-down module 21 can precisely step down the high voltage of the mains power or AC power to a voltage value suitable for the operation of the internal circuitry of the power supply device 20. The voltage of the mains power or AC power stepped down by the first step-down module 21 to a voltage suitable for powering the internal circuitry of the power supply device 20 is usually set to 5V. 5V is a relatively common and stable voltage value that can meet the requirements of the power supply device 20. The normal operation of various internal electronic components ensures that the power supply unit 20 can operate stably and efficiently. Then, the other side of the input terminal is connected to the voltage output terminal through the second step-down module 22, which is used to further step down the voltage after the first step-down to a safe voltage for electrolysis, which can usually be set to 1.2V. The electrolysis process has strict requirements on voltage. Too high a voltage may cause the electrolysis reaction to be too violent, or even cause a safety accident; while too low a voltage may prevent the electrolysis reaction from proceeding normally. Therefore, controlling the voltage at 1.2V can ensure the effective progress of the electrolysis reaction and maximize the safety of use.

[0059] During implementation, a switch can be installed at the output end of the power supply device 20. Through the switch, the user can manually control the on and off of the voltage output of the power supply device 20, thereby controlling the start and stop of electrolysis. This manual control method is simple and easy to understand, allowing users to control the start and stop of electrolysis at any time according to their actual needs, greatly improving the flexibility and safety of the electric heating container.

[0060] Furthermore, in one feasible implementation, please refer to Figure 5 , Figure 5 This is a schematic diagram of the specific structure of the power supply device 20. The power supply device 20 also includes: Resistor R, the first end of resistor R is connected to the input terminal, and is used for voltage division; The thermistor NTC has its first terminal connected to the first terminal of the resistor R, and its second terminal grounded. The NTC signal output terminal is connected to the first terminal of the thermistor NTC and is used to detect changes in the resistance value of the thermistor NTC.

[0061] In this embodiment, the power supply device 20 further includes a resistor R, a thermistor NTC, and an NTC signal output terminal. One end of the resistor R is connected to the input terminal, and the other end is connected to the thermistor NTC to divide the voltage of the circuit and prevent short circuits or malfunctions. The other end of the thermistor NTC is grounded and changes according to the detected temperature change of the liquid in the electric heating container. During the operation of the electric heating container, the temperature of the liquid in the container will continuously change. The thermistor NTC can sensitively sense these temperature changes. When the liquid temperature rises, the resistance value of the thermistor NTC will decrease accordingly; conversely, when the liquid temperature falls, its resistance value will increase. Through this correspondence between resistance value and temperature, the thermistor NTC can convert the temperature change of the liquid into a change in electrical signal. One end of the NTC signal output terminal is connected to the first terminal of the thermistor NTC, and the other end is connected to the control chip. The temperature of the liquid in the electric heating container is detected by detecting the voltage change at the first terminal of the thermistor NTC.

[0062] Furthermore, in one feasible implementation, the NTC signal output terminal is connected to a control chip, which is used to control the output of the safety voltage according to preset temperature conditions.

[0063] In this embodiment, the NTC signal output terminal is connected to the control chip. The control chip can convert the detected voltage change into a temperature change through a preset program, and control the output of the safe voltage at the output terminal according to the preset temperature conditions. Specifically, during the heating process of the electric heating container, the resistance of the NTC changes with the temperature, which causes the voltage at the NTC signal output terminal to change. The NTC signal output terminal transmits the voltage change to the control chip, and the control chip outputs a control signal through the micro power signal line 84 based on the preset program to control the on and off of the voltage output terminal, thereby controlling the electrolysis to start or stop.

[0064] The following specific example further illustrates this control process. During the operation of the electric heating container, different temperature conditions can be set according to different needs to control the activation of the electrolysis function. For example, it can be set that when the liquid is detected to be heated to 80 degrees Celsius, the control chip will determine that the preset temperature condition has been reached. Then, it will output a control signal through the micro power signal line 84 to activate the safe voltage output at the voltage output terminal, thereby activating the electrolysis function until the entire operation of the electric heating container ends and the circuit is de-energized. Alternatively, it can be set that when the liquid is detected to be heated to boiling, the control chip will also recognize this temperature condition and output a control signal to activate the safe voltage output, thereby activating the electrolysis function until the entire operation of the electric heating container ends and the circuit is de-energized.

[0065] Additionally, please refer to Figure 5During the operation of the electric heating container, the power supply device 20 outputs a 1.2V voltage and connects to the first electrode part 30, while the second electrode part 40 is grounded. The 1.2V voltage is connected to the ground through the liquid in the electric heating container, forming a circuit, thereby electrolyzing the liquid in the electric heating container.
