[0037] The present application proposes a magnesium rod assembly 1000, combined with Figure 1 , Figure 2 and Figure 4 As shown, the magnesium rod assembly 1000 includes a magnesium rod 1100, a first conductive member 1200, a stopper 1300 and an insulating member 1600. The first conductive member 1200 is connected to the magnesium rod 1100, and the first conductive member 1200 includes a first part 1210. The stopper 1300 is arranged in the first part 1210, with the length direction of the magnesium rod assembly 1000 as the axial direction, and the stopper 1300 is protruded relative to the first part 1210 along the radial direction, and the insulating member 1600 wraps the first part 1210 and the stopper 1300.

[0038] The stopper 1300 is disposed on the first portion 1210 of the first conductive member 1200, and the stopper 1300 protrudes radially relative to the first portion 1210. When the insulating member 1600 covers the first portion 1210 and the stopper 1300, the bonding force between the insulating member 1600 and the first conductive member 1200 can be enhanced, thereby effectively preventing the first conductive member 1200 from being separated from the insulating member 1600.

[0039] Specifically, the magnesium rod assembly 1000 is described in detail below using a water heater as an example. The orientation in this article is based on the installation environment of the water heater. The side close to the ground is the lower (bottom), and the side away from the ground is the upper (top).

[0040] The magnesium rod assembly 1000 includes a magnesium rod 1100, a first conductive member 1200, a stopper 1300, a resistor 1500, a second conductive member 1400 and an insulating member 1600. The magnesium rod 1100 is consumed as an anode. There are many materials for preparing the magnesium rod 1100. For example, the magnesium rod 1100 can be prepared from a rare earth magnesium alloy material. The rare earth magnesium alloy material includes a magnesium alloy and a rare earth. It can be understood that the magnesium alloy inevitably contains impurities during the preparation process. The impurities include at least one of iron, copper, silicon, and nickel. By adding rare earth to the magnesium alloy, it is beneficial to reduce the impurity content in the rare earth magnesium alloy material, thereby reducing the corrosion effect of impurities on the magnesium alloy, so that the prepared magnesium rod 1100 has high current efficiency, and can reduce the corrosion rate of the magnesium rod 1100 and reduce the shedding of particles of the magnesium rod 1100, which has the effect of improving the service life and safety of the magnesium rod 1100.

[0041] The first conductive member 1200 and the second conductive member 1400 are made of conductive materials, for example, the first conductive member 1200 and the second conductive member 1400 are made of carbon steel. The first conductive member 1200 is connected to the magnesium rod 1100, the second conductive member 1400 is connected to the inner tank of the water heater, one end of the resistor 1500 is connected to the first conductive member 1200, and the other end of the resistor 1500 is connected to the second conductive member 1400. By setting the resistor 1500, the resistance of the magnesium rod assembly 1000 can be increased, thereby reducing the current intensity, and then slowing down the corrosion rate of the magnesium rod 1100, so as to achieve the effect of extending the service life of the magnesium rod 1100. It can be understood that the resistance of the resistor 1500 can be set according to actual needs, and is not limited here. In some embodiments, the resistance of the resistor 1500 can be 100 ohms to 200 ohms, for example, the resistance of the resistor 1500 is 100 ohms, 150 ohms or 200 ohms.

[0042] The first conductive member 1200 includes a first portion 1210, the second conductive member 1400 includes a second portion 1410, one end of the resistor 1500 is connected to the first conductive member 1200, and the other end of the resistor 1500 is connected to the second conductive member 1400. Specifically, this can be achieved by connecting one end of the resistor 1500 to the first portion 1210 and 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 can be achieved by winding or by welding, can be directly connected, can be connected by wires, and of course can be connected in other ways.

[0043] On the premise of setting the resistor 1500, the resistor 1500 is protected and the connection and fixation between the first conductive member 1200 and the second conductive member 1400 is achieved by setting the insulating member 1600. The insulating member 1600 wraps the first part 1210, the resistor 1500 and the second part 1410. The insulating member 1600 wraps the first part 1210 and the second part 1410 to achieve the connection and fixation between the first part 1210 and the second part 1410. The insulating member 1600 wraps the resistor 1500 so that the resistor 1500 is not easily disconnected from the first conductive member 1200 and / or the second conductive member 1400, thereby ensuring the conduction of the circuit. It can be understood that the insulating member 1600 is made of insulating material, for example, made of plastic material, ceramic material or rubber material.

[0044] When the magnesium rod assembly 1000 is installed inside the water heater tank, the second conductive member 1400 is connected to the water heater tank. For example, the second conductive member 1400 also includes a fourth portion 1420, and the fourth portion 1420 is connected to the water heater tank by a threaded connection. In this way, the magnesium rod assembly 1000 is suspended and installed inside the water heater tank. At this time, the second conductive member 1400, the insulating member 1600, the first conductive member 1200 and the magnesium rod 1100 are arranged from top to bottom. Since the magnesium rod 1100 has a certain weight, the gravity exerted on the magnesium rod 1100 is borne by the first conductive member 1200. In order to avoid the magnesium rod assembly 1000 from being used for a long time, the first conductive member 1200 is placed on the magnesium rod 1100. Under the action of weight, the insulating part 1600 is separated. In the present embodiment, a stopper 1300 is provided, and the stopper 1300 is arranged on the first part 1210. The length direction of the magnesium rod assembly 1000 is axial, and the stopper 1300 is convex relative to the first part 1210 along the radial direction. The insulating part 1600 not only wraps the first part 1210, the resistor 1500 and the second part 1410, but also wraps the stopper 1300. The surface of the structure formed by the combination of the first part 1210 and the stopper 1300 is concave and convex, so that the bonding force between the first part 1210 and the insulating part 1600 can be enhanced, thereby improving the pulling performance, making it more difficult for the first conductive part 1200 to separate from the insulating part 1600.

[0045] There are many ways for the insulating part 1600 to wrap the first part 1210, the stopper 1300, the resistor 1500 and the second part 1410. For example, the insulating part 1600 wraps the first part 1210, the stopper 1300, the resistor 1500 and the second part 1410 by connecting the split parts. Alternatively, the insulating part 1600 wraps the first part 1210, the stopper 1300, the resistor 1500 and the second part 1410 during the molding process to further improve the bonding strength. The insulating part 1600 can wrap the first part 1210, the stopper 1300, the resistor 1500 and the second part 1410 during the molding process by placing the first part 1210, the stopper 1300, the resistor 1500 and the second part 141 in a mold, injecting the material constituting the insulating part 1600 into the mold for molding, and simultaneously wrapping the first part 1210, the stopper 1300, the resistor 1500 and the second part 1410.

[0046] In some embodiments, the first part 1210 is a screw and the stopper 1300 is a nut. Specifically, the first part 1210 is a screw, that is, the first part 1210 is a cylinder with a spiral groove cut on the outer surface, which has a simple structure and is easy to process. The stopper 1300 is a nut, so the stopper 1300 is set on the first part 1210 in a rotating and twisting manner, which is easy to operate. It can be understood that when the first part 1210 is a screw and the stopper 1300 is a nut, the stopper 1300 needs to be rotated and twisted to move along the first part 1210. When it is wrapped by the insulating member 1600, the stopper 1300 is difficult to rotate, which effectively prevents the stopper 1300 from detaching from the first part 1210. In addition, since the outer surface of the first part 1210 has a spiral groove, it also constitutes a concave-convex structure, which cooperates with the wrapping of the insulating member 1600 to further enhance the bonding force between the first part 1210 and the insulating member 1600.

[0047] Combination Figure 1 and Figure 2As shown, in some embodiments, the first conductive member 1200 further includes a third portion 1220, and the magnesium rod 1100 wraps the third portion 1220 to connect and fix. Specifically, the magnesium rod 1100 wraps the third portion 1220, so that the magnesium rod 1100 and the third portion 1220 have a larger contact area, which is conducive to increasing the bonding force between the third portion 1220 and the magnesium rod 1100. It can be understood that the magnesium rod 1100 wrapping the third portion 1220 can be achieved in a variety of ways, such as placing the third portion 1220 in a mold for preparing the magnesium rod 1100, injecting the material constituting the magnesium rod 1100 into the mold, and the magnesium rod 1100 wrapping the third portion 1220 during the molding process, or the magnesium rod 1100 can be prepared separately, and the magnesium rod 1100 has a corresponding hole position, and the third portion 1220 is connected to the hole position so as to be wrapped by the magnesium rod 1100.

[0048] In some embodiments, the third part 1220 is a screw, that is, the third part 1220 is a cylinder with a spiral groove cut on the outer surface, which has a simple structure and is easy to process. Since the outer surface of the third part 1220 has a spiral groove, it also forms a concave-convex structure, which cooperates with the wrapping of the magnesium rod 1100 to further enhance the bonding force between the magnesium rod 1100 and the third part 1220. When the third part 1220 is a screw, in addition to being wrapped by the magnesium rod 1100 during the molding process of the magnesium rod 1100, the third part 1220 can also be connected to the magnesium rod 1100 in a screwing manner so as to be wrapped by the magnesium rod 1100 (the magnesium rod 1100 has a corresponding hole position, the hole position has an internal thread, and the third part 1220 is screwed into the hole position of the magnesium rod 1100 so as to be wrapped by the magnesium rod 1100).

[0049] Combination Figure 1 , Figure 2 and Figure 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 in sequence, and a first step space 1223 is arranged between the first head portion 1221 and the first rod portion 1222 .

[0050] Specifically, the first conductive member 1200 is an integrally formed member, that is, the first conductive member 1200 is integrally formed with a first portion 1210 and a third portion 1220, and the third portion 1220 includes a first head 1221 and a first rod 1222. The first head 1221, the first rod 1222 and the first portion 1210 are sequentially arranged, and when the magnesium rod assembly 1000 is suspended and installed, the first portion 1210, the first rod 1222 and the first head 1221 are arranged from top to bottom, and a first step space 1223 is arranged between the first head 1221 and the first rod 1222, that is, the first head 1221 is convexly arranged relative to the first rod 1222 along the radial direction, so that the surface of the third portion 1220 forms a concave-convex structure, strengthens the bonding force between the third portion 1220 and the magnesium rod 1100, improves the pulling performance, and makes it difficult for the magnesium rod 1100 to separate from the first conductive member 1200. On the premise that the third part 1220 includes the first head 1221 and the first rod 1222 , the first rod 1222 can be designed as a screw, which, together with the wrapping of the magnesium rod 1100 , can further enhance the bonding force between the magnesium rod 1100 and the third part 1220 .

[0051] In some embodiments, the second part 1410 is a screw. That is, the second part 1410 is a cylinder with a spiral groove cut on the outer surface, which has a simple structure and is easy to process. By setting it in this way, the outer surface of the second part 1410 forms a concave-convex structure, which cooperates with the wrapping of the insulating member 1600 to enhance the bonding force between the insulating member 1600 and the second part 1410. When the magnesium rod assembly 1000 is suspended and installed, the second part 1410 (the second conductive member 1400) is located above the insulating member 1600, and the insulating member 1600 is not easy to separate from the second part 1410.

[0052] Combination Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, the second part 1410 includes a second head 1411 and a second rod 1412. The second head 1411 and the second rod 1412 are arranged in sequence in a direction away from the first conductive member 1200, and a second step space 1413 is provided between the second head 1411 and the second rod 1412.

[0053] Specifically, the second conductive member 1400 is an integrally formed member, that is, the second conductive member 1400 is integrally formed with a second portion 1410 and a fourth portion 1420, the second portion 1410 includes a second head portion 1411 and a second rod portion 1412, and the fourth portion 1420 is used to be connected and fixed to the inner tank of the water heater, so that the magnesium rod assembly 1000 is suspended and installed inside the inner tank of the water heater. The second head 1411 and the second rod 1412 are arranged in sequence along the direction away from the first conductive member 1200, that is, when the magnesium rod assembly 1000 is suspended and installed inside the water heater, the second conductive member 1400 is located above the first conductive member 1200, the fourth part 1420 is located above the second part 1410, and the second rod 1412 is located above the second head 1411. A second step space 1413 is provided between the second head 1411 and the second rod 1412, that is, the second head 1411 is radially convex relative to the second rod 1412, so that a concave-convex structure is formed on the surface of the second part 1410, thereby strengthening the bonding force between the second part 1410 and the insulating member 1600, so that the insulating member 1600 is not easily separated from the second part 1410. On the premise that the second part 1410 includes the second head 1411 and the second rod 1412 , the second rod 1412 can be designed as a screw, which, together with the wrapping of the insulating member 1600 , can further enhance the bonding force between the insulating member 1600 and the second part 1410 .

[0054] Combination Figure 2 As shown, in some embodiments, the first conductive member 1200 is integrally formed with a first head portion 1221 and a first rod portion 1222 , and the first head portion 1221 is suitable for being formed by stamping and flattening, thereby facilitating the formation of the first step space 1223 .

[0055] Specifically, the first head 1221 is manufactured by stamping and flattening. After the first head 1221 is flattened, the first head 1221 can be radially protruded relative to the first rod 1222, so as to form a first step space 1223 between the first rod 1222. For example, the first conductive member 1200 is an integrally formed member, and the third portion 1220 is a screw. The first head 1221 can be formed by flattening the corresponding portion of the third portion 1220, and the portion that is not flattened can form the first rod 1222, which is convenient and quick.

[0056] Combination Figure 4 As shown, in some embodiments, the second conductive member 1400 is integrally formed with the second head 1411 and the second rod 1412 , and the second head 1411 is suitable for being stamped and flattened, so as to facilitate the formation of the second step space 1413 .

[0057] Specifically, the second head 1411 is manufactured by stamping and flattening. After the second head 1411 is flattened, the second head 1411 can be radially protruded relative to the second rod 1412, so as to form a second step space 1413 between the second rod 1412. For example, the second conductive member 1400 is an integrally formed member, and the second portion 1410 is a screw. The second head 1411 can be formed by flattening the corresponding portion of the second portion 1410, and the portion that is not flattened can form the second rod 1412, which is convenient and quick.

[0058] The second aspect of the present application discloses a water heater, Figures 1 to 5 As shown, the water heater includes a water heater inner tank and the above-mentioned magnesium rod assembly 1000, and the second conductive member 1400 of the magnesium rod assembly 1000 is connected to the water heater inner tank, so that the magnesium rod assembly 1000 is installed in the water heater inner tank. For example, the second conductive member 1400 includes a fourth portion 1420, and the fourth portion 1420 and the water heater inner tank are threadedly connected to fix the magnesium rod assembly 1000 to the water heater inner tank, so that the magnesium rod assembly 1000 is suspended and installed inside the water heater inner tank.

[0059] Specifically, the magnesium rod assembly 1000 includes a magnesium rod 1100, a first conductive member 1200, a stopper 1300, a resistor 1500, a second conductive member 1400 and an insulating member 1600. The magnesium rod 1100 is consumed as an anode, and there are many materials for preparing the magnesium rod 1100. For example, the magnesium rod 1100 can be prepared from a rare earth magnesium alloy material, and the rare earth magnesium alloy material includes a magnesium alloy and a rare earth. It can be understood that the magnesium alloy inevitably contains impurities during the preparation process, and the impurities include at least one of iron, copper, silicon, and nickel. By adding rare earth to the magnesium alloy, it is beneficial to reduce the impurity content in the rare earth magnesium alloy material, thereby reducing the corrosion effect of impurities on the magnesium alloy, so that the prepared magnesium rod 1100 has high current efficiency, and can reduce the corrosion rate of the magnesium rod 1100 and reduce the shedding of particles of the magnesium rod 1100, which has the effect of improving the service life and safety of the magnesium rod 1100.

[0060] The first conductive member 1200 and the second conductive member 1400 are made of conductive materials, for example, the first conductive member 1200 and the second conductive member 1400 are made of carbon steel. The first conductive member 1200 is connected to the magnesium rod 1100, the second conductive member 1400 is connected to the inner tank of the water heater, one end of the resistor 1500 is connected to the first conductive member 1200, and the other end of the resistor 1500 is connected to the second conductive member 1400. By setting the resistor 1500, the resistance of the magnesium rod assembly 1000 can be increased, thereby reducing the current intensity, and then slowing down the corrosion rate of the magnesium rod 1100, so as to achieve the effect of extending the service life of the magnesium rod 1100. It can be understood that the resistance of the resistor 1500 can be set according to actual needs, and is not limited here. In some embodiments, the resistance of the resistor 1500 can be 100 ohms to 200 ohms, for example, the resistance of the resistor 1500 is 100 ohms, 150 ohms or 200 ohms.

[0061] The first conductive member 1200 includes a first portion 1210, the second conductive member 1400 includes a second portion 1410, one end of the resistor 1500 is connected to the first conductive member 1200, and the other end of the resistor 1500 is connected to the second conductive member 1400. Specifically, this can be achieved by connecting one end of the resistor 1500 to the first portion 1210 and 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 can be achieved by winding or by welding, can be directly connected, can be connected by wires, and of course can be connected in other ways.

[0062] On the premise of setting the resistor 1500, the resistor 1500 is protected and the connection and fixation between the first conductive member 1200 and the second conductive member 1400 is achieved by setting the insulating member 1600. The insulating member 1600 wraps the first part 1210, the resistor 1500 and the second part 1410. The insulating member 1600 wraps the first part 1210 and the second part 1410 to achieve the connection and fixation between the first part 1210 and the second part 1410. The insulating member 1600 wraps the resistor 1500 so that the resistor 1500 is not easily disconnected from the first conductive member 1200 and / or the second conductive member 1400, thereby ensuring the conduction of the circuit. It can be understood that the insulating member 1600 is made of insulating material, for example, made of plastic material, ceramic material or rubber material.

[0063] When the magnesium rod assembly 1000 is suspended and installed inside the inner tank of the water heater, the second conductive member 1400 is connected to the inner tank of the water heater. For example, the second conductive member 1400 also includes a fourth part 1420, and the fourth part 1420 is connected to the inner tank of the water heater by a threaded connection. In this way, the magnesium rod assembly 1000 is suspended and installed inside the inner tank of the water heater. At this time, the second conductive member 1400, the insulating member 1600, the first conductive member 1200 and the magnesium rod 1100 are arranged from top to bottom. Since the magnesium rod 1100 has a certain weight, the gravity exerted on the magnesium rod 1100 is borne by the first conductive member 1200. In order to avoid the magnesium rod assembly 1000 from being used for a long time, the first conductive member 1200 is attached to the magnesium rod 1100. Under the action of the weight, the insulating member 1600 is separated from the insulating member 1600. In the present embodiment, a stopper 1300 is provided, and the stopper 1300 is arranged on the first part 1210. With the length direction of the magnesium rod assembly 1000 as the axial direction, the stopper 1300 is convexly arranged relative to the first part 1210 along the radial direction. The insulating member 1600 not only wraps the first part 1210, the resistor 1500 and the second part 1410, but also wraps the stopper 1300. The surface of the structure formed by the combination of the first part 1210 and the stopper 1300 is concave and convex, so that the bonding force between the first part 1210 and the insulating member 1600 can be enhanced, thereby improving the pulling performance, making it more difficult for the first conductive member 1200 to separate from the insulating member 1600.

[0064] It is understandable that the water heater includes the magnesium rod assembly 1000 of the above embodiment. The magnesium rod assembly 1000 of this embodiment adopts the technical solution of the above embodiment, and therefore has at least the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.

[0065] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made based on the concept of the present application and the contents of the present application description and drawings, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
