[0016] Optionally, the inner wall of the cavity is provided with a positioning component, which includes a first positioning part, and a first electrode and a second electrode are fixedly disposed in the cavity at a distance from each other through the first positioning part.

[0017] Optionally, the shell is a cylinder, and at least one bottom surface of the cavity is provided with a plurality of ribs arranged radially along the shell.

Each first positioning part forms at least two positioning bands intersecting the axis of the shell along the radial direction of the shell. The mounting hole is provided on one of the bottom surfaces of the shell and the axis of the mounting hole coincides with the axis of the shell.

[0018] The first electrode and the second electrode are spaced apart and are bent along the circumference of the housing and pass through the positioning strip. The first terminal and the second terminal extend from the mounting hole and are spaced apart on both sides of the axis of the housing.

[0019] Optionally, the positioning component may further include a second positioning part and a third positioning part.

[0020] The second positioning part is fixed to the inner wall of the cavity and abuts against the end of the first electrode away from the mounting hole, so as to restrict the first electrode from moving circumferentially along the housing.

[0021] The third positioning part is fixed to the inner wall of the cavity and spaced apart from the second positioning part. The third positioning part abuts against the end of the second electrode away from the mounting hole to restrict the second electrode from moving circumferentially along the housing.

[0022] Optionally, the kettle body includes a partition plate with through holes. The partition plate is disposed in the receiving cavity and divides the receiving cavity into a first receiving part and a second receiving part communicating with the first receiving part.

[0028] This utility model has the following beneficial effects:

[0029] In this embodiment, the electric kettle is used by placing a heating element inside the kettle's cavity. An external power source is connected to the power supply unit to power the heating unit, which then heats the element inside the cavity. Furthermore, when the power supply unit is connected to the external power source, the first electrode is electrically connected to the power supply unit via a first terminal, and the second electrode is electrically connected to the power supply unit via a second terminal. This creates a potential difference between the first and second electrodes, electrolyzing the water in the cavity and producing hydrogen gas at the cathode, thus generating negative hydrogen water.

[0030] Because the first and second electrodes are spaced apart and do not contact each other, each surface of both electrodes can participate in the reaction. The first and second electrodes can fully utilize their surface areas for electrolysis, thus increasing the electrolysis area between them. Simultaneously, the electrolysis assembly can operate concurrently with the heating unit. The heating unit's heating of the material increases the temperature within the containment cavity, thereby promoting the electrolysis reaction. Therefore, the electric kettle provided by this invention improves electrolysis efficiency, increases hydrogen production, and increases the hydrogen content of the negative hydrogen water.

Detailed Implementation

[0039] The technical solutions of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0040] In this utility model, descriptions involving "first," "second," etc., 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 that feature.

[0041] While reactive oxygen species (ROS) in the human body play a role in immunity, excessive amounts can damage normal cells and tissues, leading to various diseases such as heart disease, Alzheimer's disease, Parkinson's disease, and tumors. In daily life, radiation, ultraviolet rays, electromagnetic waves, radiation therapy received by cancer patients, and environmental pollution can all generate large amounts of harmful ROS in the body.

[0042] Negative hydrogen water is water rich in hydrogen. Research has shown that the active hydrogen in negative hydrogen water can effectively remove harmful reactive oxygen species (ROS) from the body. The hydrogen molecules in negative hydrogen water are so small that they can enter the body and quickly permeate throughout the body. After penetrating cell membranes, hydrogen molecules neutralize harmful ROS and are excreted as water, without affecting other beneficial ROS or bodily functions. Simultaneously, hydrogen molecules can repair damaged cells and cell membranes. Therefore, regular consumption of negative hydrogen water can effectively promote metabolism, maintain the health of each cell, remove blemishes, and delay aging.

[0043] Electric kettles are common small household appliances, and there are currently many types and brands available, offering consumers a wide variety of choices. To enhance competitiveness among electric kettles with similar functions and performance, and to gain consumer favor, consumers are demanding new features beyond simply boiling water. Among these, the ability to generate negative hydrogen water in electric kettles has become a focus for manufacturers, reflecting the growing emphasis on health.

[0044] Existing electric kettles have multiple electrode plates installed inside the kettle, with diaphragms between each electrode plate to produce negative hydrogen water through electrolysis between the electrode plates. However, the electrode plates in existing electric kettles are blocked by the diaphragms, and can only utilize a portion of their surface for electrolysis, resulting in low electrolysis efficiency.

[0045] See Figures 1 to 2 As shown, this embodiment provides an electric kettle 100, including a kettle body 110 with a receiving cavity 111, a heating unit 112 fixed to the kettle body 110, a power supply unit for supplying power to the heating unit 112, and an electrolysis assembly disposed in the receiving cavity 111.

[0046] The electrolysis assembly includes at least one electrode unit fixed in the receiving cavity 111. Each electrode unit includes a first electrode 132 fixed in the receiving cavity 111 and a second electrode 133 spaced apart from the first electrode 132. The first electrode 132 has a first terminal 132a, and the second electrode 133 has a second terminal 133a spaced apart from the first terminal 132a. The first terminal 132a and the second terminal 133a are electrically connected to a power supply unit to form a potential difference between the first electrode 132 and the second electrode 133.

[0047] It should be noted that, in this embodiment, the receiving cavity 111 of the kettle body 110 is used to hold the heating material, such as drinking water, tea, or traditional Chinese medicine. The heating unit 112 is used to heat the heating material inside the kettle body 110, and the heating unit 112 can be a heating tube, etc. In the electrolysis assembly, one of the first electrode 132 and the second electrode 133 serves as the cathode, and the other serves as the anode. The materials of the first electrode 132 and the second electrode 133 can be selected according to the application requirements, and this application does not impose any restrictions.

[0048] In this embodiment, the electric kettle 100 is used such that a heating element is placed in the receiving cavity 111 of the kettle body 110. An external power supply is connected to the power supply unit to power the heating unit 112, so that the heating unit 112 heats the heating element in the receiving cavity 111. Furthermore, when the power supply unit is connected to the external power supply unit, the first electrode 132 is electrically connected to the power supply unit through the first terminal 132a, and the second electrode 133 is electrically connected to the power supply unit through the second terminal 133a, thereby generating a potential difference between the first electrode 132 and the second electrode 133. This electrolyzes the water in the receiving cavity 111 and produces hydrogen gas at the cathode, generating negative hydrogen water.

[0049] In this embodiment, the first electrode 132 and the second electrode 133 are spaced apart and do not contact each other. Therefore, each surface of the first electrode 132 and the second electrode 133 can participate in the reaction. Furthermore, this embodiment does not provide a diaphragm between the first electrode 132 and the second electrode 133, so there is no external obstruction between them, allowing them to fully utilize their own surfaces for electrolysis. Thus, the electrolysis assembly in this embodiment increases the electrolysis area between the first electrode 132 and the second electrode 133, improves electrolysis efficiency and hydrogen production, and increases the hydrogen content of the negative hydrogen water. Simultaneously, the electrolysis assembly can operate simultaneously with the heating unit 112. The heating unit 112's heating of the heated material increases the temperature within the receiving cavity 111, thereby promoting the electrolysis reaction of the electrolysis assembly, further improving electrolysis efficiency and hydrogen production, and consequently increasing the hydrogen content of the negative hydrogen water.

[0050] Optionally, to further increase the hydrogen content of the negative hydrogen water, the electrolysis component is fixed at the bottom of the receiving cavity 111 so that the hydrogen generated by electrolysis diffuses from the bottom to the top of the receiving cavity 111, extending the contact time between the hydrogen and the liquid in the receiving cavity 111.

[0051] See Figures 3 to 5As shown, in one embodiment, to increase the electrolytic area of ​​the first electrode 132 and the second electrode 133, at least one of the first electrode 132 and the second electrode 133 is bent, or the first electrode 132 and the second electrode 133 are bent simultaneously. The first electrode 132 and the second electrode 133 can be bent into a wavy shape, a spiral shape, or a ring-shaped spiral shape. Of course, in other embodiments, multiple electrode units can be provided to increase the electrolytic area and improve electrolysis efficiency by increasing the number of electrodes.

[0052] In one embodiment, to further increase the electrolytic area of ​​the first electrode 132 and the second electrode 133 and reduce the resistance, the first electrode 132 and the second electrode 133 are respectively arranged in a spiral shape around the same center line, the center line extending along the thickness direction of the wall of the pot body 110, and the first electrode 132 and the second electrode 133 at least partially overlap in the direction along the center line.

[0053] It should be noted that by configuring both the first electrode 132 and the second electrode 133 in a spiral shape, the electrolytic area of ​​the electrodes can be further increased without increasing the number of electrodes. That is, one electrode corresponds to one terminal; reducing the number of electrodes reduces the number of terminals, thereby lowering contact resistance and improving electrolytic efficiency. Furthermore, when the first electrode 132 and the second electrode 133 overlap at least partially along the centerline, the contact resistance can be further reduced, thus improving electrolytic efficiency.

[0054] In one embodiment, to further reduce the contact resistance between the two spiral electrodes and improve the electrolysis efficiency, the spacing between the first electrode 132 and the second electrode 133 is set to a gradual process.

[0055] It should be noted that when the first electrode 132 and the second electrode 133 are set in a spiral shape, the resistance between the ends of the first electrode 132 and the second electrode 133 closer to the center line is greater and the current is smaller. Therefore, setting the spacing between the first electrode 132 and the second electrode 133 to a gradual process can balance the contact resistance and improve the electrolysis efficiency.

[0056] The distance between the first electrode 132 and the second electrode 133 gradually decreases or increases from their ends near the center line to their ends away from the center line. Of course, in other embodiments, the distance between the first electrode 132 and the second electrode 133 can also be increased or decreased from their ends toward the middle.

[0057] Optionally, to improve electrolysis efficiency and the negative hydrogen content of the purified negative hydrogen water, the distance between the first electrode 132 and the second electrode 133 is set to 0.5 mm to 5 mm.

[0058] In one embodiment, to facilitate the processing of the two spiral electrodes and to balance the contact resistance, the distance between the first electrode 132 and the second electrode 133 is equal. A first terminal 132a is located at the middle position of the first electrode 132, and the distance from the middle position of the first electrode 132 to both ends of the first electrode 132 is equal. Similarly, a second terminal 133a is located at the middle position of the second electrode 133, and the distance from the middle position of the second electrode 133 to both ends of the second electrode 133 is equal. That is, when the distance between the first electrode 132 and the second electrode 133 is equal, the spiral first electrode 132 is unfolded, giving it length. The first terminal 132a is located at the middle position of the unfolded first electrode 132, and the distance from the first terminal 132a to the two ends of the first electrode 132 spaced apart along its length is equal. Accordingly, the spiral-shaped second electrode 133 is unfolded to give it length, and the second terminal 133a is positioned at the middle of the unfolded second electrode 133, such that the distance from the second terminal 133a to the two ends of the second electrode 133 that are spaced apart along its length is equal. This arrangement facilitates the processing of the first electrode 132 and the second electrode 133, and also ensures that the contact resistance between the first electrode 132 and the second electrode 133 is balanced after energization, thereby improving electrolysis efficiency.

[0059] In one embodiment, to facilitate connection of the electrolysis assembly to the power supply unit, the distance between the first electrode 132 and the second electrode 133 gradually decreases from their ends near the center line to their ends away from the center line. A first terminal 132a is located at the end of the first electrode 132 near the center line, and a second terminal 133a is located at the end of the second electrode 133 near the center line. That is, by placing the first terminal 132a and the second terminal 133a near the center line, it is easier to connect them to the power supply unit and to reduce the space occupied by the electrolysis assembly.

[0060] In one embodiment, to facilitate the fixing of the first electrode 132 and the second electrode 133 within the receiving cavity 111, the electrolysis assembly further includes a housing 131. The housing 131 is fixed within the receiving cavity 111, and the first electrode 132 and the second electrode 133 are fixed within the housing 131 and spaced apart. That is, by installing the first electrode 132 and the second electrode 133 into the receiving cavity 111 through the housing 131, the assembly and disassembly of the first electrode 132 and the second electrode 133 can be achieved by directly disassembling and assembling the housing 131, resulting in high assembly efficiency. The housing 131 can be a plate-like structure or a groove-like structure. The housing 131 can be fixed within the receiving cavity 111 by means of fastening, snap-fitting, threading, screwing, or connection via connectors.

[0061] In other embodiments, to improve the connection stability between the housing 131 and the receiving cavity 111, the housing 131 may also be integrally formed with the receiving cavity 111.

[0062] In one embodiment, to prevent particulate matter within the containment cavity 111 from obscuring the surfaces of the first electrode 132 and the second electrode 133, the housing 131 is provided with a cavity 134 and a mounting hole 135 communicating with the cavity 134. The first electrode 132 and the second electrode 133 are spaced apart within the cavity 134 of the housing 131, and the first terminal 132a and the second terminal 133a extend out of the mounting hole 135 and are electrically connected to the power supply unit. At least a portion of the wall surface of the housing 131 is used to allow the liquid from the containment cavity 111 to enter the cavity 134 for electrolysis.

[0063] It should be noted that when the heating material loaded in the receiving cavity 111 contains particulate matter, such as tea leaves added when heating tea, the shell 131 can prevent the tea leaves and other particulate matter from entering the cavity 134 and obstructing the surfaces of the two electrodes, thus avoiding affecting the electrolytic performance of the electrolysis assembly. Simultaneously, to meet the electrolysis requirements, the wall surface of the shell 131 needs to allow the liquid in the receiving cavity 111 to enter the cavity for electrolysis, and for the hydrogen gas generated by electrolysis to enter the receiving cavity 111 to form negative hydrogen water, while preventing particulate matter in the receiving cavity 111 from entering the cavity 134. For example, the shell 131 can be mesh-like, with the mesh opening diameter smaller than the particle size.

[0064] Furthermore, to facilitate the connection between the two electrodes and the power supply unit, the housing 131 has mounting holes 135, through which the two terminals can extend into the cavity 134 and connect electrically to the power supply unit. Further, to prevent particulate matter from entering the cavity 134 through the mounting holes 135, the mounting holes 135 are blocked after the two terminals extend out. For example, the mounting holes 135 can be sealed with adhesive. To facilitate the processing of the housing 131 and improve processing efficiency, one mounting hole 135 can be machined on the housing 131, and the two terminals can extend from the same mounting hole 135 at intervals and then be sealed with adhesive. Of course, in other embodiments, to facilitate the spacing between the two terminals, two mounting holes 135 can be provided on the housing 131, with the two terminals extending from different mounting holes 135.

[0065] See Figures 3 to 6As shown, in one embodiment, to facilitate fixing the two electrodes, a positioning assembly is provided on the inner wall of the cavity 134. The positioning assembly includes a first positioning part 136, and the first electrode 132 and the second electrode 133 are fixedly positioned in the cavity 134 at a distance through the first positioning part 136. The first positioning part 136 can be a recessed portion in the inner wall of the cavity 134, in which case the first electrode 132 and the second electrode 133 are respectively embedded in different recesses to achieve a spaced arrangement. Alternatively, the first positioning part 136 can be a protrusion protruding from the inner wall of the cavity 134, with a groove formed between the two protrusions. In this case, the first electrode 132 and the second electrode 133 are respectively embedded in different grooves to achieve a spaced arrangement.

[0066] In other embodiments, when the first electrode 132 and the second electrode 133 are directly fixed to the inner wall of the receiving cavity 111, the positioning component can be directly disposed on the inner wall of the receiving cavity 111, which is equivalent to providing a recessed portion in the inner wall of the receiving cavity 111 or a protrusion protruding from the inner wall of the receiving cavity 111.

[0067] In one embodiment, to facilitate the assembly of the spiral electrode and reduce the volume of the housing 131, the housing 131 is a cylinder. At least one bottom surface of the cavity 134 is provided with a plurality of ribs 136a arranged radially along the housing 131. The interval between two adjacent ribs 136a forms a first positioning part 136. Each first positioning part 136 forms at least two positioning bands intersecting the axis of the housing 131 along the radial direction of the housing 131. The mounting hole 135 is provided on one bottom surface of the housing 131 and the axis of the mounting hole 135 coincides with the axis of the housing 131.

[0068] The first electrode 132 and the second electrode 133 are spaced apart and are bent along the circumference of the housing 131 and pass through the positioning strip. The first terminal 132a and the second terminal 133a extend from the mounting hole 135 and are spaced apart on both sides of the axis of the housing 131.

[0069] It should be noted that the cylindrical housing 131 can meet the installation requirements of the spiral electrode and saves installation space. The two positioning bands formed by the multiple first positioning parts 136 can fix the two electrodes from multiple angles, improving the installation stability of the electrodes and minimizing surface obstruction. Optionally, the two positioning bands are arranged perpendicular to each other. Meanwhile, the mounting hole 135, located on the axis of the housing 131, allows the two terminals to be led out of the housing 131 from the same mounting hole 135.

[0070] See Figure 5As shown, in one embodiment, to facilitate further fixation of the two electrodes, the positioning assembly further includes a second positioning portion 137 and a third positioning portion 138. The second positioning portion 137 is fixed to the inner wall of the cavity 134 and abuts against the end of the first electrode 132 away from the mounting hole 135, thereby restricting the first electrode 132 from moving circumferentially along the housing 131. The third positioning portion 138 is fixed to the inner wall of the cavity 134 and spaced apart from the second positioning portion 137. The third positioning portion 138 abuts against the end of the second electrode 133 away from the mounting hole 135, thereby restricting the second electrode 133 from moving circumferentially along the housing 131.

[0071] It should be noted that the second positioning part 137 and the third positioning part 138 can be configured as strip-shaped protrusions, in which case the extension direction of the strip-shaped protrusions extends radially along the housing 131. Alternatively, the second positioning part 137 and the third positioning part 138 can be configured as L-shaped protrusions, in which case one side of the L-shaped protrusion extends radially along the housing 131, and the other side of the L-shaped protrusion extends circumferentially along the housing 131. The first electrode 132 abuts against the two sides of the L-shaped protrusion of the second positioning part 137, and the second electrode 133 abuts against the two sides of the L-shaped protrusion of the third positioning part 138.

[0072] See Figure 1 As shown, in one embodiment, to facilitate the installation of the heating unit 112 and the power supply unit, the kettle body 110 includes a partition plate 113 with a through hole. The partition plate 113 is disposed in the receiving cavity 111 and divides the receiving cavity 111 into a first receiving portion 111a and a second receiving portion 111b communicating with the first receiving portion 111a. The first receiving portion 111a is used to load the heating object, and the heating unit 112 and the power supply unit are fixed in the second receiving portion 111b. The outer wall of the housing 131 is provided with a boss 131c, and a mounting hole 135 is disposed in the boss 131c. The boss 131c is fixed in the through hole of the partition plate 113 to separate the first receiving portion 111a and the second receiving portion 111b.

[0073] It should be noted that the partition plate 113 divides the accommodating cavity 111 of the kettle body 110 into dry and wet parts. This not only facilitates the heating unit 112 in heating the object, but also protects the heating unit 112 and the power supply unit from corrosion by impurities and extends their service life. Furthermore, it allows the electrolysis components to generate negative hydrogen water while the electric kettle 100 is heating, thereby increasing the temperature, promoting electrolysis efficiency, and increasing the negative hydrogen content of the negative hydrogen water.

[0074] Meanwhile, to facilitate the assembly of the electrolysis assembly and the separator 113, the boss 131c of the housing 131 is embedded in the through hole of the separator 113 to achieve a fixed connection between the two, saving time and effort. At the same time, the boss 131c is located on the outer wall of the housing 131 to avoid occupying the space in the cavity 134, so as to avoid obstructing the surfaces of the two electrodes, and the side wall of the boss 131c and the through hole of the separator can seal the two receiving parts.

[0075] See Figure 3 As shown, in one embodiment, to facilitate the replacement of the electrodes in the cavity 134, the housing 131 includes a first connector 131a fixed to the receiving cavity 111 and a second connector 131b forming the cavity 134 with the first connector 131a, and the first connector 131a and the second connector 131b are detachable.

[0076] In one embodiment, to facilitate temperature control, the electric kettle 100 further includes a controller and a temperature sensor 140. The controller is electrically connected to the power supply unit, and the temperature sensor 140 is fixed to the kettle body 110 and electrically connected to the controller. That is, the temperature sensor 140 is used to detect the liquid temperature in the containing cavity 111 and feeds the detection signal back to the controller. The controller can control the heating unit 112 and the electrolysis assembly according to user-set parameters.

[0077] See Figure 1 and Figure 3 As shown, in one embodiment, the electric kettle 100 further includes a base detachably connected to the kettle body 110. The heating unit 112 is a heating element fixed to the kettle body 110. The power supply unit includes a first circuit unit fixed to the kettle body 110 and a second circuit unit fixed to the base. The first circuit unit includes a first contact point disposed outside the receiving cavity 111 and fixed to the kettle body 110. The second circuit unit includes a second contact point corresponding to the first contact point and a plug for connecting to a power source. The first terminal 132a of the first electrode 132 is electrically connected to the first circuit unit. The second terminal 133a of the second electrode 133 is electrically connected to the first circuit unit.

[0078] When the kettle body 110 is installed on the base, the plug of the power supply unit is connected to the power source, and the first contact point and the second contact point are electrically connected to conduct the first circuit unit and the second circuit unit, so that a potential difference is formed between the first electrode 132 and the second electrode 133, and then electrolysis is performed. At the same time, the heating element begins to heat the heating material in the receiving cavity 111.

[0079] See Figure 1As shown, in another embodiment, the electric kettle 100 further includes a base detachably connected to the kettle body 110. The heating unit 112 includes a magnetically conductive part fixed to the bottom of the kettle body 110 and an electromagnetic coil fixed to the base. The power supply unit includes a circuit unit fixed to the base and a plug for connecting to a power source. The first terminal 132a of the first electrode 132 and the second terminal 133a of the second electrode 133 are electrically connected to the circuit unit, respectively.

[0080] When the kettle body 110 is installed on the base, the plug of the power supply unit is connected to the power source, and a potential difference is formed between the first electrode 132 and the second electrode 133, thereby performing electrolysis. At the same time, the rapidly changing current in the circuit unit flows through the electromagnetic coil to generate a rapidly changing magnetic field. When the magnetic lines of force in the magnetic field pass through the magnetic conductive part at the bottom of the kettle body 110, a large number of strong eddy currents are generated, which in turn generate a large amount of heat, heating the heating element in the receiving cavity 111.
