Description

Technical Field

[0001] This utility model relates to the field of magnesium rod technology for electric water heaters, and in particular to a double-hole oxide rod. Background Technology

[0002] Magnesium rods, commonly known as magnesium anodes or magnesium anode blocks, are used to prevent corrosion of the metal inner tank and soften water. When using a Tiscoelastic or manganese steel metal inner tank, the principle of sacrificial anode protection of the cathode is utilized, with the magnesium rod acting as the anode and the metal inner tank as the cathode. In water heaters, the magnesium rod is installed in the middle of the metal inner tank. When the enamel coating on the surface of the metal inner tank is intact, the enamel shields the metal inner tank, and the insulation resistance between the magnesium rod and the metal inner tank can reach over 2MΩ, with the magnesium (rod) anode output current almost zero. However, when a crack appears in the enamel inner tank, a small resistance is formed between the magnesium anode and the metal inner tank through the water, and the magnesium anode begins to output current. This current flows to the exposed metal inner tank, creating a polarization film that repairs the damaged enamel, insulating the metal inner tank and preventing corrosion. Because the magnesium anode itself consumes current during output, this method is called the sacrificial anode method.

[0003] Currently, most electric water heaters on the market use a design where the magnesium rod and the mounting base are molded as a single piece. From a materials perspective, the mounting base is usually made of corrosion-resistant, high-strength special engineering plastics or metal alloys, which are themselves quite expensive. When the magnesium rod reaches the end of its service life, even if the mounting base still has good physical properties and usability, it must be discarded along with the magnesium rod, resulting in a large amount of material waste and exacerbating resource consumption and environmental pressure.

[0004] In terms of cost, the one-piece molding design significantly increases replacement costs. The magnesium rod, being a consumable part, needs to be replaced periodically depending on water quality and usage frequency. Furthermore, the material cost of the mounting bracket accounts for a considerable portion of the overall replacement cost, forcing users to pay extra for the still-usable bracket each time a replacement is needed. Over the long term, the accumulated replacement costs place a significant financial burden on consumers.

[0005] Furthermore, the disassembly and installation process is cumbersome, time-consuming, and labor-intensive. Because the mounting bracket is tightly connected to the inner tank of the water heater, disassembly requires the use of various specialized tools to carefully separate the one-piece molded magnesium rod and the mounting bracket from the complex internal structure. The slightest carelessness may damage the inner tank of the water heater. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dual-pore oxide rod.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A dual-hole oxide rod includes a fixed base and a magnesium rod body. A fixed ring is fixedly provided inside the fixed base, and a movable ring is provided between the fixed base and the fixed ring. A movable seat is provided inside the fixed base, and multiple disassembly blocks are fixedly provided on the movable seat. Multiple disassembly ports corresponding to the disassembly blocks are provided on the fixed ring, and multiple mounting slots are provided on the movable seat. Each mounting slot is provided with a mounting bracket that is fixedly connected to the magnesium rod body.

[0009] Preferably, multiple springs are provided between the fixed base and the fixed ring, and both ends of the multiple springs are respectively connected to the fixed base and the outer wall of the movable ring.

[0010] Preferably, a positioning rod is fixedly provided on the disassembly block, and a positioning hole corresponding to the positioning rod is provided on the fixing ring.

[0011] Preferably, the number of the disassembly port, disassembly block, positioning hole, positioning rod and spring are all four, and the number of the mounting groove, mounting bracket and magnesium rod body are all two.

[0012] Preferably, the four disassembly ports, disassembly blocks, positioning holes, positioning rods and springs are all circumferentially spaced at equal intervals, and the two mounting slots, mounting brackets and magnesium rod bodies are also circumferentially spaced at equal intervals.

[0013] Preferably, the four disassembly ports and positioning holes are staggered, the vertical cross-section of the mounting groove is T-shaped, and the vertical cross-section of the mounting bracket is I-shaped.

[0014] The beneficial effects of this utility model are:

[0015] This dual-hole oxide rod features a detachable structure for both the magnesium rod body and the mounting base. When the magnesium rod reaches the end of its service life, only the magnesium rod body needs to be replaced, while the mounting base can be reused. This avoids waste of the mounting base, effectively reduces replacement costs, and minimizes material loss, which aligns with environmental protection principles.

[0016] Through the ingenious design of the disassembly blocks, disassembly ports, positioning rods, and positioning holes, combined with the elastic potential energy of the springs, the movable seat and the fixed seat can be quickly installed and disassembled. During installation, only simple rotation and pressing are required; during disassembly, lifting and rotating are sufficient for separation. Compared with traditional one-piece structures, this significantly shortens installation and replacement time, reduces operational difficulty, facilitates user self-maintenance, and reduces maintenance costs for professionals.

[0017] The T-shaped and I-shaped design of the mounting slot and mounting bracket creates a good limiting effect, ensuring that the magnesium rod body will not move arbitrarily during use; at the same time, the compression of the moving ring by the spring makes the positioning rod firmly locked into the positioning hole, further enhancing the stability of the overall structure, ensuring that the magnesium rod continues to function when the electric water heater is working, and extending its service life.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4 A dual-hole oxide rod includes a fixed base 1 and a magnesium rod body 7. A fixed ring 8 is fixedly provided inside the fixed base 1. A movable ring 11 is provided between the fixed base 1 and the fixed ring 8. A movable base 2 is provided inside the fixed base 1. Multiple disassembly blocks 3 are fixedly provided on the movable base 2. Multiple disassembly ports 9 corresponding to the disassembly blocks 3 are provided on the fixed ring 8. Multiple mounting slots 5 are provided on the movable base 2. Each mounting slot 5 is provided with a mounting bracket 6 that is fixedly connected to the magnesium rod body 7.

[0025] Multiple springs 12 are provided between the fixed base 1 and the fixed ring 8, with both ends of the springs 12 connected to the fixed base 1 and the outer wall of the movable ring 11, respectively. The elastic potential energy provided by the springs 12 enables the movable ring 11 to be pressed down. When the disassembly block 3 is between the fixed ring 8 and the movable ring 11, and the disassembly block 3 is offset from the disassembly port 9 and corresponds to the positioning rod 4 and the positioning hole 10, the positioning rod 4 can be pushed into the positioning hole 10.

[0026] A positioning rod 4 is fixedly provided on the disassembly block 3, and a positioning hole 10 corresponding to the positioning rod 4 is provided on the fixing ring 8. When the positioning rod 4 is in the positioning hole 10, the movable seat 2 is installed in the fixed seat 1, the mounting bracket 6 is in the mounting groove 5, and the arc-shaped outer wall is restricted by the inner wall of the fixed seat 1 and will not move.

[0027] There are four disassembly / assembly ports 9, four disassembly / assembly blocks 3, four positioning holes 10, four positioning rods 4, and four springs 12. There are two mounting slots 5, two mounting brackets 6, and two magnesium rod bodies 7. The four disassembly / assembly ports 9, four disassembly / assembly blocks 3, four positioning holes 10, four positioning rods 4, and four springs 12 are all circumferentially evenly spaced. The two mounting slots 5, two mounting brackets 6, and two magnesium rod bodies 7 are also circumferentially evenly spaced.

[0028] The four disassembly ports 9 and the positioning holes 10 are staggered. With the staggered distribution, the movable seat 2 can rotate relative to the fixed seat 1 to realize the rotation adjustment of the disassembly block 3, so that it corresponds to the disassembly port 9 or the positioning hole 10.

[0029] The vertical cross-section of mounting slot 5 is T-shaped, while the vertical cross-section of mounting bracket 6 is I-shaped. This configuration has a limiting effect, allowing mounting bracket 6 to be installed and removed from mounting slot 5 only by moving horizontally.

[0030] In use, the magnesium rod body 7 is fixedly mounted on the mounting bracket 6, which is located within the mounting groove 5. The movable seat 2 is located within the fixed seat 1, and the arc-shaped outer wall of the mounting bracket 6 contacts the arc-shaped inner wall of the fixed seat 1. At this time, the mounting bracket 6 cannot move relative to the mounting groove 5, thus achieving stable installation of the magnesium rod body 7 relative to the movable seat 2. The disassembly block 3 enters between the fixed ring 8 and the movable ring 11 through the disassembly port 9, and pushes the movable ring 11, compressing the spring 12. The disassembly block 3 rotates 45 degrees with the movable seat 2, and then the disassembly block 3 is misaligned with the disassembly port 9. The positioning rod 4... As the disassembly block 3 rotates to align with the positioning hole 10, it stops pushing the movable seat 2 and other components. The spring 12 returns to its original position, causing the movable ring 11 to descend and press the disassembly block 3. The disassembly block 3 then moves the positioning rod 4 into the positioning hole 10, thus completing the installation of multiple components. During disassembly, the movable seat 2 and other components are pushed up to disengage the positioning rod 4 from the positioning hole 10. Then, the movable seat 2 and other components are rotated so that the disassembly block 3 aligns with the disassembly port 9, allowing the fixed seat 1 and movable seat 2 and other components to be vertically separated. Finally, the mounting bracket 6 and other components are moved horizontally relative to the mounting groove 5 to complete the disassembly of the magnesium rod body 7 and other components.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
