[0029] The present disclosure provides a magnesium rod assembly 1000. As illustrated in FIG. 1, FIG. 2, and FIG. 4, the magnesium rod assembly 1000 includes a magnesium rod 1100, a first conductor 1200, a stop member 1300, and an insulation member 1600. The first conductor 1200 is connected to the magnesium rod 1100 and includes a first portion 1210. The stop member 1300 is disposed at the first portion 1210. By taking a length direction of the magnesium rod assembly 1000 as an axial direction, the stop member 1300 protrudes with respect to the first portion 1210 in a radial direction. The first portion 1210 and the stop member 1300 are molded in the insulation member 1600.

[0030] The stop member 1300 is disposed at the first portion 1210 of the first conductor 1200 and protrudes with respect to the first portion 1210 in the radial direction. When the insulation member 1600 wraps the first portion 1210 and the stop member 1300, a bonding force between the insulation member 1600 and the first conductor 1200 can be enhanced, effectively preventing the first conducive member 1200 from being separated from the insulation member 1600.

[0031] Specifically, the magnesium rod assembly 1000 is described in detail below by taking a water heater as an example. Orientations in the present disclosure are referenced to a use environment in which the water heater is mounted. A side close to ground is a lower side (bottom), while a side away from the ground is an upper side (top).

[0032] The magnesium rod assembly 1000 includes a magnesium rod 1100, a first conductor 1200, a stop member 1300, a resistor 1500, a second conductor 1400, and an insulation member 1600. The magnesium rod 1100 serves as an anode to be consumed and can be made of various materials. For example, the magnesium rod 1100 may be made of a rare earth magnesium alloy containing magnesium alloy and rare earth. It should be understood that the magnesium alloy inevitably contains impurities in a preparation process. The impurities include at least one of iron, copper, silicon, nickel, or the like. By adding the rare earth to the magnesium alloy, an impurity content in the rare earth magnesium alloy can be advantageously reduced, which attenuates a corrosion effect of the impurities on the magnesium alloy, allowing the prepared magnesium rod 1100 to have a high current efficiency. In addition, a corrosion rate of the magnesium rod 1100 and shedding of particles from the magnesium rod 1100 can be reduced, prolonging a service life of the magnesium rod 1100 and improving use safety of the magnesium rod 1100.

[0033] The first conductor 1200 and the second conductor 1400 are made of a conductive material. For example, the first conductor 1200 and the second conductor 1400 are both made of carbon steel. The first conductor 1200 is connected to the magnesium rod 1100. The second conductor 1400 is connected to the inner tank of the water heater. An end of the resistor 1500 is connected to the first conductor 1200, and the other end of the resistor 1500 is connected to the second conductor 1400. By disposing the resistor 1500, a resistance value of the magnesium rod assembly 1000 can be increased to reduce a current intensity and thus to slow down the corrosion rate of the magnesium rod 1100, thereby prolonging the service life of the magnesium rod 1100. It should be understood that the resistance value of the resistor 1500 may be set as desired and is not limited herein. In some embodiments, the resistance value of the resistor 1500 may range from 100 ohms to 200 ohms, e.g., 100 ohms, 150 ohms, or 200 ohms.

[0034] The first conductor 1200 includes a first portion 1210. The second conductor 1400 includes a second portion 1410. An end of the resistor 1500 is connected to the first conductor 1200 by connecting the end of the resistor 1500 to the first portion 1210, and the other end of the resistor 1500 is connected to the second conductor 1400 by connecting the other end of the resistor 1500 to the second portion 1410. A connection between the resistor 1500 and the first portion 1210 and a connection between the resistor 1500 and the second portion 1410 may be achieved through winding, welding, a direct connection, or a wire. Of course, the connection may be realized in other ways.

[0035] Under the premise that the resistor 1500 is provided, the insulation member 1600 is disposed to protect the resistor 1500 and to connect and fix the first conductor 1200 and the second conductor 1400. The first portion 1210, the resistor 1500, and the second portion 1410 are molded in the insulation member 1600. The insulation member 1600 wraps the first portion 1210 and the second portion 1410 to connect and fix the first portion 1210 and the second portion 1410. The insulation member 1600 wraps the resistor 1500 in such a manner that the resistor 1500 is less likely to be disconnected from the first conductor 1200 and / or the second conductor 1400, ensuring the conduction of circuit. It should be understood that the insulation member 1600 is made of an insulation material, such as plastic, ceramic, or rubber.

[0036] When the magnesium rod assembly 1000 is mounted inside an inner tank of a water heater, the second conductor 1400 is connected to the inner tank of the water heater. For example, the second conductor 1400 further includes a fourth portion 1420. The fourth portion 1420 is connected to the inner tank of the water heater through threads, in such a manner that the magnesium rod assembly 1000 is suspended and is mounted inside the inner tank of the water heater. In this case, the second conductor 1400, the insulation member 1600, the first conductor 1200, and the magnesium rod 1100 are arranged from top to bottom. Due to the certain weight of the magnesium rod 1100, gravity of the magnesium rod 1100 is borne by the first conductor 1200. To prevent the first conductor 1200 from being separated from the insulation member 1600 under the weight of the magnesium rod 1100 subsequent to a long-term use of the magnesium rod assembly 1000, the stop member 1300 is provided in the present embodiment. The stop member 1300 is disposed at the first portion 1210. By taking a length direction of the magnesium rod assembly 1000 as an axial direction, the stop member 1300 is disposed to protrude with respect to the first portion 1210 in a radial direction. Not only the first portion 1210, the resistor 1500, and the second portion 1410, but also the stop member 1300 are molded in the insulation member 1600. A surface of a structure formed by the first portion 1210 and the stop member 1300 in combination is of an uneven shape. In this way, a bonding force between the first conductor 1200 and the insulation member 1600 can be intensified to improve pulling performance. In this way, the first conductor 1200 is less likely to be separated from the insulation member 1600.

[0037] The first portion 1210, the stop member 1300, the resistor 1500, and the second portion 1410 can be wrapped by the insulation member 1600 in various manners. For example, the first portion 1210, the stop member 1300, the resistor 1500, and the second portion 1410 may be wrapped by the insulation member 1600 in a way of connecting separate parts; or the first portion 1210, the stop member 1300, the resistor 1500, and the second portion 1410 may be wrapped by the insulation member 1600 in a molding process of the insulation member 1600 to further reinforce bonding strength. That “the first portion 1210, the stop member 1300, the resistor 1500, and the second portion 1410 are wrapped by the insulation member 1600 in the molding process of the insulation member 1600” may mean that the first portion 1210, the stop member 1300, the resistor 1500, and the second portion 141 are placed into a mold, and a material for preparing the insulation member 1600 is injected into the mold for molding, to simultaneously wrap the first portion 1210, the stop member 1300, the resistor 1500, and the second portion 1410.

[0038] In some embodiments, the first portion 1210 is a screw rod, and the stop member 1300 is a nut. In particular, that “the first portion 1210 is a screw rod” means that the first portion 1210 is a cylinder having a spiral groove cut on an outer surface of the cylinder, which is simple in structure and easy to process. The stop member 1300 is the nut, and thus the stop member 1300 is disposed at the first portion 1210 by rotating and screwing into the first portion1210, which is easy to operate. It should be understood that, when the first portion 1210 is the screw rod and the stop member 1300 is the nut, the stop member 1300 needs to be rotated and screwed to move along the first portion 1210. When the stop member 1300 is wrapped by the insulation member 1600, the stop member 1300 is less likely to rotate, effectively preventing the stop member 1300 from being separated from the first portion 1210. In addition, due to the spiral groove on the outer surface of the first portion 1210, an uneven structure is also formed, which further intensifies a bonding force between the first portion 1210 and the insulation member 1600 in conjunction with wrapping of the insulation member 1600.

[0039] As illustrated in FIG. 1 and FIG. 2, in some embodiments, the first conductor 1200 further includes a third portion 1220. The magnesium rod 1100 wraps the third portion 1220 to realize a connection and a fixation. Specifically, a large contact area between the magnesium rod 1100 and the third portion 1220 can be formed through wrapping the third portion 1220 by the magnesium rod 1100, which advantageously increases a bonding force between the third portion 1220 and the magnesium rod 1100. It should be understood that the third portion 1220 may be wrapped by the magnesium rod 1100 in various ways. For example, the third portion 1220 is placed into a mold for preparing the magnesium rod 1100, and a material for preparing the magnesium rod 1100 is injected into the mold, to wrap the third portion 1220 in a molding process of the magnesium rod 1100. Alternatively, the magnesium rod 1100 may be prepared separately and has a corresponding hole, and the third portion 1220 is connected to the corresponding hole and thus wrapped by the magnesium rod 1100.

[0040] In some embodiments, the third portion 1220 is a screw rod. That is, the third portion 1220 is a cylinder having a spiral groove cut at an outer surface of the third portion 1220, which is simple in structure and easy to process. Since the outer surface of the third portion 1220 has the spiral groove, an uneven structure is also formed, which further intensifies the bonding force between the magnesium rod 1100 and the third portion 1220 in conjunction with the wrapping of the magnesium rod 1100. When the third portion 1220 is the screw rod, the third portion 1220 can be wrapped by the magnesium rod 1100 in the molding process of the magnesium rod 1100; or the third portion 1220 can also be connected to the magnesium rod 1100 by screwing into the magnesium rod 1100, enabling the third portion 1220 to be wrapped by the magnesium rod 1100 (i.e., the magnesium rod 1100 has a corresponding hole having an internal thread, and the third portion 1220 is screwed into the corresponding hole of the magnesium rod 1100 to be wrapped by the magnesium rod 1100).

[0041] As illustrated in FIG. 1, FIG. 2, and FIG. 3, in some embodiments, the third portion 1220 includes a first head portion 1221 and a first rod portion 1222. The first head portion 1221, the first rod portion 1222, and the first portion 1210 are arranged sequentially. A first step space 1223 is formed between the first head portion 1221 and the first rod portion 1222.

[0042] Specifically, the first conductor 1200 is integrally molded. That is, the first portion 1210 and the third portion 1220 of the first conductor 1200 are integrally formed, and the third portion 1220 includes the first head portion 1221 and the first rod portion 1222. The first head portion 1221, the first rod portion 1222, and the first portion 1210 are arranged sequentially. When the magnesium rod assembly 1000 is suspended and mounted, the first portion 1210, the first rod portion 1222, and the first head portion 1221 are arranged from top to bottom. By forming the first step space 1223 between the first head portion 1221 and the first rod portion 1222, i.e., by enabling the first head portion 1221 to protrude with respect to the first rod portion 1222 in the radial direction, an uneven structure is formed on a surface of the third portion 1220, which intensifies the bonding force between the third portion 1220 and the magnesium rod 1100 to improve the pulling performance. In this way, the magnesium rod 1100 is less likely to be separated from the first conductor 1200. When the third portion 1220 includes the first head portion 1221 and the first rod portion 1222, the first rod portion 1222 may be designed as the screw rod, and thus the bonding force between the magnesium rod 1100 and the third portion 1220 can be intensified in conjunction with the wrapping of the magnesium rod 1100.

[0043] In some embodiments, the second portion 1410 is a screw rod. That is, the second portion 1410 is a cylinder having a spiral groove cut at an outer surface of the second portion 1410, which is simple in structure and easy to process. With such an arrangement, an uneven structure is formed at the outer surface of the second portion 1410, which intensifies a bonding force between the insulation member 1600 and the second portion 1410 in conjunction with the wrapping of the insulation 1600. When the magnesium rod assembly 1000 is suspended and mounted, the second portion 1410 (the second conductor 1400) is located above the insulation member 1600, and thus the insulation member 1600 is less likely to be separated from the second portion 1410.

[0044] As illustrated in FIG. 1, FIG. 4, and FIG. 5, in some embodiments, the second portion 1410 includes a second head portion 1411 and a second rod portion 1412. The second head portion 1411 and the second rod portion 1412 are arranged sequentially in a direction away from the first conductor 1200. A second step space 1413 is formed between the second head portion 1411 and the second rod portion 1412.

[0045] Specifically, the second conductor 1400 is integrally molded. That is, the second portion 1410 and the fourth portion 1420 of the second conductor 1400 are integrally formed, and the second portion 1410 includes the second head portion 1411 and the second rod portion 1412. The fourth portion 1420 is connected and fixed to the inner tank of the water heater. In this way, the magnesium rod assembly 1000 is suspended and mounted inside the inner tank of the water heater. The second head portion 1411 and the second rod portion 1412 are arranged sequentially in the direction away from the first conductor 1200. That is, when the magnesium rod assembly 1000 is suspended and mounted inside the water heater, the second conductor 1400 is located above the first conductor 1200, the fourth portion 1420 is located above the second portion 1410, and the second rod portion 1412 is located above the second head portion 1411. By forming the second step space 1413 between the second head portion 1411 and the second rod portion 1412, i.e., by enabling the second head portion 1411 to protrude with respect to the second rod portion 1412 in the radial direction, an uneven structure is formed at a surface of the second portion 1410, which intensifies the bonding force between the second portion 1410 and the insulation member 1600. In this way, the insulation member 1600 is less likely to be separated from the second portion 1410. Under the premise that the second portion 1410 includes the second head portion 1411 and the second rod portion 1412, the second rod portion 1412 may be designed as the screw rod, which further intensifies the bonding force between the insulation member 1600 and the second portion 1410 in conjunction with the wrapping of the insulation member 1600.

[0046] As illustrated in FIG. 2, in some embodiments, the first head portion 1221 and the first rod portion 1222 of the first conductor 1200 are integrally formed, and the first head portion 1221 is adapted to be stamped into a flat shape, facilitating the formation of the first step space 1223.

[0047] Specifically, the first head portion 1221 is manufactured through stamping into a flat shape. When the first head portion 1221 is stamped into a flat shape, the first head portion 1221 can protrude with respect to the first rod portion 1222 in the radial direction, facilitating the formation of the first step space 1223 between the first head portion 1221 and the first rod portion 1222. For example, the first conductor 1200 is integrally formed and the third portion 1220 is the screw rod. The first head portion 1221 is formed by a corresponding part of the third portion 1220 that is flattened, while the first rod portion 1222 is formed by a part of the third portion 1220 that is not subjected to flattening, which is convenient and quick.

[0048] As illustrated in FIG. 4, in some embodiments, the second head portion 1411 and the second rod portion 1412 of the second conductor 1400 are integrally formed. The second head portion 1411 is adapted to be stamped into a flat shape, facilitating the formation of the second step space 1413.

[0049] Specifically, the second head portion 1411 is manufactured through stamping into a flat shape. When the second head portion 1411 is flattened, the second head portion 1411 can protrude with respect to the second rod portion 1412 in the radial direction, which facilitates the formation of the second step space 1413 between the second head portion 1411 and the second rod portion 1412. For example, the second conductor 1400 is integrally formed and the second portion 1410 is the screw rod. The second head portion 1411A is formed by a corresponding part of the second portion 1410 that is flattened, while the second rod portion 1412 is formed by a part of the second portion 1410 that is not subjected to the flattening, which is convenient and quick.

[0050] In a second aspect of the present disclosure, the water heater is disclosed. As illustrated in FIG. 1 to FIG. 5, the water heater includes an inner tank and the above-mentioned magnesium rod assembly 1000. The second conductor 1400 of the magnesium rod assembly 1000 is connected to the inner tank of the water heater, to mount the magnesium rod assembly 1000 to the inner tank of the water heater. For example, the second conductor 1400 includes a fourth portion 1420. The fourth portion 1420 is connected to the inner tank of the water heater through threads to fix the magnesium rod assembly 1000 to the inner tank of the water heater. In this way, the magnesium rod assembly 1000 is suspended and mounted inside the inner tank of the water heater.

[0051] Specifically, the magnesium rod assembly 1000 includes a magnesium rod 1100, a first conductor 1200, a stop member 1300, a resistor 1500, a second conductor 1400, and an insulation member 1600. The magnesium rod 1100 serves as an anode to be consumed and can be made of various materials. For example, the magnesium rod 1100 may be made of a rare earth magnesium alloy containing magnesium alloy and rare earth. It should be understood that the magnesium alloy inevitably contains impurities in the preparation process. The impurities include at least one of iron, copper, silicon, nickel, or the like. By adding the rare earth to the magnesium alloy, the impurity content in the rare earth magnesium alloy can be advantageously reduced, which attenuates the corrosion effect of the impurities on the magnesium alloy, allowing the prepared magnesium rod 1100 have a high current efficiency. In addition, a corrosion rate of the magnesium rod 1100 and shedding of particles from the magnesium rod 1100 can be reduced, prolonging a service life of the magnesium rod 1100 and improving use safety of the magnesium rod 1100.

[0052] The first conductor 1200 and the second conductor 1400 are made of a conductive material. For example, the first conductor 1200 and the second conductor 1400 are both made of carbon steel. The first conductor 1200 is connected to the magnesium rod 1100. The second conductor 1400 is connected to the inner tank of the water heater. An end of the resistor 1500 is connected to the first conductor 1200, and the other end of the resistor 1500 is connected to the second conductor 1400. By disposing the resistor 1500, a resistance value of the magnesium rod assembly 1000 can be increased to reduce the current intensity and thus to slow down the corrosion rate of the magnesium rod 1100, thereby prolonging the service life of the magnesium rod 1100. It should be understood that the resistance value of the resistor 1500 may be set as desired and is not limited herein. In some embodiments, the resistance value of the resistor 1500 may range from 100 ohms to 200 ohms, e.g., 100 ohms, 150 ohms, or 200 ohms.

[0053] The first conductor 1200 includes a first portion 1210. The second conductor 1400 includes a second portion 1410. An end of the resistor 1500 is connected to the first conductor 1200 by connecting the end of the resistor 1500 to the first portion 1210, and the other end of the resistor 1500 is connected to the second conductor 1400 by connecting the other end of the resistor 1500 to the second portion 1410. The connection between the resistor 1500 and the first portion 1210 and the connection between the resistor 1500 and the second portion 1410 may be achieved through winding, welding, a direct connection, or a wire. Of course, the connection may be realized in other ways.

[0054] Under the premise that the resistor 1500 is provided, the insulation member 1600 is disposed to protect the resistor 1500 and to connect and fix the first conductor 1200 and the second conductor 1400. The first portion 1210, the resistor 1500, and the second portion 1410 are molded in the insulation member 1600. The insulation member 1600 wraps the first portion 1210 and the second portion 1410 to connect and fix the first portion 1210 and the second portion 1410. The insulation member 1600 wraps the resistor 1500 in such a manner that the resistor 1500 is less likely to be disconnected from the first conductor 1200 and / or the second conductor 1400, ensuring the conduction of circuit. It should be understood that the insulation member 1600 is made of the insulation material, such as plastic, ceramic, or rubber.

[0055] When the magnesium rod assembly 1000 is suspended and mounted inside the inner tank of the water heater, the second conductor 1400 is connected to the inner tank of the water heater. For example, the second conductor 1400 further includes a fourth portion 1420. The fourth portion 1420 is connected to the inner tank of the water heater through threads, in such a manner that the magnesium rod assembly 1000 is suspended and mounted inside the inner tank of the water heater. In this case, the second conductor 1400, the insulation member 1600, the first conductor 1200, and the magnesium rod 1100 are arranged from top to bottom. Since the magnesium rod 1100 has a certain weight, the gravity of the magnesium rod 1100 is borne by the first conductor 1200. To prevent the first conductor 1200 from being separated from the insulation member 1600 under the weight of the magnesium rod 1100 subsequent to a long-term use of the magnesium rod assembly 1000, the stop member 1300 is provided in the present embodiment. The stop member 1300 is disposed at the first portion 1210. By taking a length direction of the magnesium rod assembly 1000 as an axial direction, the stop member 1300 is disposed to protrude with respect to the first portion 1210 in a radial direction. Not only the first portion 1210, the resistor 1500, and the second portion 1410, but also the stop member 1300 are molded in the insulation member 1600. A surface of a structure formed by the first portion 1210 and the stop member 1300 in combination is of the uneven shape. In this way, the bonding force between the first conductor 1200 and the insulation member 1600 can be intensified to improve the pulling performance. In this way, the first conductor 1200 is less likely to be separated from the insulation member 1600.

[0056] It should be understood that the water heater includes the magnesium rod assembly 1000 according to the above embodiments. The magnesium rod assembly 1000 according to the present embodiment adopts the technical solutions according to the above embodiments, the water heater at least provides the advantageous effects brought about by the technical solutions according to the above embodiments, and thus details thereof will be omitted here.

[0057] The preferred embodiments of the present disclosure are described above. However, the scope of the present disclosure is not limited to these embodiments. Without departing from the concept of the present disclosure, any equivalent structural transformation made using the contents of the specification and the accompanying drawings of the present disclosure, or any direct or indirect application of the contents of the specification and the accompanying drawings of the present disclosure in other related fields shall fall within the scope of the present disclosure.
