[0044] Figure 1 This is a schematic side cross-sectional view of a magnesium rod structure according to an exemplary embodiment, such as... Figure 1 As shown, the magnesium rod structure includes: magnesium rod 1, support 2, pull-out box 3, and water pump 4.

[0045] Magnesium rod 1 is inserted into the water storage tank of the water heater. The bottom of magnesium rod 1 is fitted onto bracket 2. Pull-out box 3 is installed on bracket 2 at a position corresponding to the bottom of magnesium rod 1. The bottom of magnesium rod 1 is inserted into the cavity of pull-out box 3.

[0046] In this embodiment, the magnesium rod 1 is used to protect the inner tank of the water heater from corrosion. The magnesium rod 1 reacts chemically with calcium and magnesium ions in the water, preventing these ions from reacting with the metal of the inner tank. When the magnesium rod is depleted, it needs to be replaced to ensure the normal operation of the water heater and extend its service life.

[0047] In this embodiment, the bracket 2 is provided with a hole of a size equivalent to the cross-sectional size of the magnesium rod 1. The bottom of the magnesium rod 1 passes through the hole and is fitted onto the bracket 2. The pull-out box 3 is snapped onto the bracket 2 and is provided corresponding to the bottom of the magnesium rod 1. The bottom of the magnesium rod 1 is inserted into the cavity of the pull-out box 3.

[0048] The magnesium rod 1 has a hollow pipe 101 inside. The opening of the hollow pipe 101 is located on the side wall of the magnesium rod 1. The hollow pipe 101 is connected to the water inlet of the water pump 4. The water outlet of the water pump 4 is connected to the cavity of the pull-out box 3. The water pump 4 is used to drain the water remaining in the water storage tank into the pull-out box 3 during the replacement of the magnesium rod.

[0049] In this embodiment, the hollow pipe 101 has openings at both ends. One opening is located near the bottom of the magnesium rod 1, specifically on the side wall of the portion of the magnesium rod 1 that is inserted into the water heater's storage tank. The other opening is located on the bottom surface of the magnesium rod 1. The hollow pipe 101 connects the water heater's storage tank to the inlet of the water pump 4. The outlet of the water pump 4 is connected to the cavity of the pull-out box 3 via a connecting pipe. The water pump 4 is fixed to the bottom surface of the magnesium rod 1. Before the magnesium rod 1 needs to be replaced, a command is sent to the water pump 4, which draws the residual water in the storage tank into the pull-out box 3 through the hollow pipe 101, preventing residual water from flowing out during the replacement of the magnesium rod 1.

[0050] In an optional embodiment, such as Figure 2 As shown, the bottom of the magnesium rod 1 is provided with a protruding edge, which is snapped into the inner side of the bracket 2. The magnesium rod structure also includes a pressure cap 12; the pressure cap 12 is used to cooperate with the inner wall of the bracket 2 to fix the protruding edge.

[0051] In this embodiment, the pressure cap 12 is a hollow plate structure. One side of the protruding edge is attached to the inner side of the bracket 2, and the other side is attached to the pressure cap 12. The bottom of the magnesium rod 1 is fixed by the cooperation of the pressure cap 12 and the bracket 2 to press the protruding edge. In addition, the pressure cap 12 can be fixed to the bracket 2 by screws set at the four corners.

[0052] As can be seen from the above, in this embodiment of the present disclosure, the magnesium rod 1 can be fixed by snap-fitting the protruding edge at the bottom of the magnesium rod 1. The pressure cap 12 cooperates with the inner wall of the bracket 2 to fix the protruding edge at the bottom of the magnesium rod 1, thereby fixing the magnesium rod 1 and the bracket 2.

[0053] In an optional embodiment, the bracket 2 has sidewalls around its perimeter, and these sidewalls are perpendicular to the surface of the bracket 2 used to hold the pull-out box 3. Figure 2 As shown, the magnesium rod structure also includes: cover plate 5, elastic element 6, and spring cover 7.

[0054] Cover plates 5 are fixed to the inner sides of both the first and second side walls. The first and second side walls are two side walls that are arranged opposite to each other on the bracket 2.

[0055] In this embodiment, the first sidewall and the second sidewall can be two opposing sidewalls of the bracket 2, either vertically or horizontally. There are two cover plates 5, one cover plate 5 fixed to the inner side of the first sidewall and the other cover plate 5 fixed to the inner side of the second sidewall.

[0056] A spring element 6 is provided below the cover plate 5. The spring element 6 passes through the hollow part on the corresponding side wall. The spring cover 7 cooperates with the hollow part. One end of the spring element 6 is connected to the cover plate 5, and the other end is connected to the spring cover 7.

[0057] In this embodiment, both cover plates 5 have cavities below them, and each cover plate 5 has an elastic member 6 below it. The first and second side walls each have a hollow portion for the elastic member 6 below the corresponding cover plate 5 to pass through. There are also two spring covers 7, with each cover plate 5 equipped with one spring cover 7, and both spring covers 7 are matched with the shape of the hollow portion.

[0058] In this embodiment, the cover plate 5, elastic member 6, and spring cover 7 on one side of the first sidewall are arranged symmetrically with those on the second sidewall. Taking the cover plate 5, elastic member 6, and spring cover 7 on the first sidewall as an example, one end of the elastic member 6 is connected to the cover plate 5 on that side, and the other end is connected to the spring cover 7 on that side. One end of the spring cover 7 is located in the cavity below the cover plate 5, and the other end passes through the hollow part, allowing it to extend out of the first sidewall under the elastic force of the elastic member 6. Since the cover plate 5 is inside the first sidewall, and the end of the spring cover 7 located below the cover plate 5 is also inside the first sidewall, to prevent the end of the spring cover 7 located below the cover plate 5 from detaching from the cover plate 5 and the first sidewall under the elastic force of the elastic member 6, a limiting edge is also provided at the end of the spring cover 7 located below the cover plate 5. The width of the limiting edge is greater than the hollow part on the first sidewall. When the cover 7 is subjected to an external force opposite to the elastic force of the elastic member 6, the cover 7 will be completely pressed into the inner side of the first side wall.

[0059] In this embodiment, since the cover plate 5, elastic member 6 and spring cover 7 on the second sidewall are exactly the same as those on the first sidewall, they will not be described in detail here.

[0060] Based on the above, in this embodiment of the present disclosure, by providing cover plates 5 in the two side walls that are oppositely arranged on the bracket 2, and elastically connecting the cover plates 5 and the spring cover 7 by elastic members 6, the spring cover 7 can be moved by applying an external force in opposite directions; by providing elastic members 6 through the hollow parts on the corresponding side walls, and setting the spring cover 7 to cooperate with the hollow parts, the spring cover 7 can move back and forth in the hollow parts when subjected to an external force in opposite directions or an elastic force in opposite directions, so as to realize the installation and separation of the magnesium rod body structure from the water heater.

[0061] In an optional embodiment, the elastic element 6 is a spring; both the cover plate 5 and the spring cover 7 are provided with snap-fit ​​parts at the positions where they are connected to the spring, and the snap-fit ​​parts are used to snap the ends of the spring.

[0062] As can be seen from the above, in this embodiment of the present disclosure, by setting a snap-fit ​​component at the position where the cover plate 5 and the spring cover 7 are connected to the spring, the end of the spring can be fixed and positioned to prevent the end of the spring from shifting during the deformation of the spring.

[0063] In an optional embodiment, guide members are provided inside both sides of the hollow portion, and the two sides of the spring cover 7 are respectively connected to the guide members, which are used to limit the movement direction of the spring cover 7.

[0064] In this embodiment, the positions where the two sides of the spring cover 7 are connected to the guide are the limiting edges of the spring cover 7, and the moving direction of the guide and the spring cover 7, that is, the elastic force direction of the elastic member 6, are parallel.

[0065] As can be seen from the above, by providing guide members inside both sides of the hollow portion in this embodiment, the spring cover 7 can move stably in the guiding direction of the guide members when it is subjected to pressure, thus avoiding deviation in the movement direction of the spring cover 7.

[0066] In one specific implementation, the magnesium rod 1, bracket 2, pull-out box 3, water pump 4, pressure cap 12, cover plate 5, elastic element 6 and spring cover 7 can be regarded as a replacement unit, called the magnesium rod body structure. When replacing the magnesium rod, the magnesium rod body structure can be removed as a whole.

[0067] In an optional embodiment, such as Figure 3 As shown, the pull-out box 3 has a handle 301 on the outside.

[0068] In this embodiment, the handle 301 and the pull-out box 3 are integrally formed, and the pull-out box 3 can be pulled by pulling the handle 301.

[0069] As can be seen from the above, in this embodiment of the present disclosure, by providing a handle 301 on the outside of the pull-out box 3, the user can easily move the pull-out box 3, and by engaging the pull-out box 3 with the bracket 2, the magnesium rod body structure can be removed as a whole, thereby replacing the magnesium rod.

[0070] In an optional embodiment, such as Figure 4 As shown, the magnesium rod structure also includes: a pressure plate 8 and a movable cover 9.

[0071] The pressure plate 8 is sleeved on the outside of the bracket 2. The pressure plate 8 is provided with a receiving groove for receiving the movable cover 9. The inner edge of the movable cover 9 is set towards the spring cover 7, and the outer edge of the movable cover 9 is flush with the outer surface of the pressure plate 8. The movable cover 9 compresses the elastic member 6 through the spring cover 7 so that the spring cover 7 retracts into the side wall of the bracket 2.

[0072] In this embodiment, the pressure plate 8 has two receiving slots and two movable covers 9, each receiving slot accommodating one movable cover 9. The number of movable covers 9 corresponds to the number of spring covers 7. The movable covers 9 are movably connected to the pressure plate 8 and are distributed on the outside of the spring covers 7, with their inner edges facing the spring covers 7. When an external force is applied to the movable covers 9, they move inward into the pressure plate 8, pressing the spring covers 7 and pressing one end of the spring cover 7 extending beyond the side wall of the bracket 2 into the side wall of the bracket 2 under the elastic force of the elastic member 6. Correspondingly, the pressure plate 8 also has two spring cover receiving cavities, each for accommodating one end of the spring cover 7 extending beyond the side wall of the bracket 2. The receiving slots communicate with the spring cover receiving cavities. The outer edge of the movable cover 9 can be flush with the outer surface of the pressure plate 8 to maintain an aesthetically pleasing appearance.

[0073] Based on the above, in this embodiment of the present disclosure, by setting a pressure plate 8 and setting a receiving groove on the pressure plate 8, a receiving space can be provided for the movable cover 9. By setting the inner edge of the movable cover 9 toward the spring cover 7, the spring cover 7 can be pressed by pressing the movable cover 9, and the spring cover 7 can be pressed back into the side wall of the bracket 2, changing the snap-fit ​​state between the spring cover 7 and the bracket 2, so as to remove the magnesium rod body structure.

[0074] In an optional embodiment, such as Figure 4 As shown, the magnesium rod structure also includes: a spring piece 10; the spring piece 10 is disposed between the movable cover 9 and the side wall of the receiving groove.

[0075] In this embodiment of the disclosure, in order to realize the return of the movable cover 9, a spring piece 10 is provided between the movable cover 9 and the side wall of the receiving groove. After the external force applied to the movable cover 9 disappears, the spring piece 10 pops the movable cover 9 out.

[0076] In this embodiment, to prevent the movable cover 9 from detaching from the pressure plate 8 under the elastic force of the spring piece 10, the movable cover 9 is also provided with a limiting edge on its side, which engages with the side of the receiving groove of the pressure plate 8.

[0077] As can be seen from the above, in this embodiment of the present disclosure, by providing a spring piece 10 between the movable cover 9 and the side wall of the receiving groove, the movable cover 9 portion that is pressed back into the receiving groove can be pushed out of the receiving groove by the elastic force of the spring piece 10, so as to realize the return of the movable cover 9.

[0078] In an optional embodiment, such as Figure 5 The magnesium rod structure further includes: a base 11; the base 11 is used to install the bracket 2 on the outer wall of the water storage tank, and the pressure plate 8 is fixedly connected to the base 11.

[0079] In this embodiment, the base 11 is fixedly connected to the outer wall of the water storage tank of the water heater. The base 11 has a hollow structure. The magnesium rod 1 on the bracket 2 passes through the hollow structure of the base 11 and is inserted into the water storage tank. The base 11 plays a supporting role for the bracket 2.

[0080] In this embodiment, the four corners of the pressure plate 8 are fixedly connected to the four corners of the base 11 by screws.

[0081] Based on the above, in this embodiment of the present disclosure, by setting the base 11, a mounting seat can be provided for the bracket 2, or the magnesium rod body structure, so as to install the bracket 2 to the outside of the water heater; by fixing the pressure plate 8 to the base 11, the pressure plate 8 can be fixed to the base 11, so that the movable cover 9 inside the pressure plate 8 can assist in the installation and separation of the magnesium rod body structure from the water heater.

[0082] In one specific embodiment, the pressure plate 8, movable cover 9, spring piece 10, and base 11 can be considered as a whole, referred to as the disassembly assistance structure, which assists in disassembling the magnesium rod body structure. The magnesium rod structure disclosed herein includes a magnesium rod body structure and a disassembly assistance structure. The magnesium rod body structure includes a magnesium rod 1, a bracket 2, a pull-out box 3, a water pump 4, a pressure cover 12, a cover plate 5, an elastic element 6, and a spring cover 7. The disassembly assistance structure includes a pressure plate 8, movable cover 9, spring piece 10, and base 11.

[0083] Specifically, the magnesium rod structure disclosed herein is used as follows: The disassembly assistance structure is fixed to the water tank of the water heater via the base 11. One end of the spring cover 7 extending from the side wall of the bracket 2 in the magnesium rod body structure is inserted into the pressure plate 8 in the disassembly assistance structure. The magnesium rod body structure is engaged with the pressure plate 8 in the disassembly assistance structure via the spring cover 7. When the magnesium rod needs to be replaced, firstly, a command is issued to the water pump 4 to draw the residual water in the water tank into the pull-out box 3. Then, the movable covers 9 on both sides of the disassembly assistance structure are manually pressed. The movable covers 9 press the end of the spring cover 7 extending from the side wall of the bracket 2 into the inside of the bracket 2. Then, the magnesium rod body structure is removed via the handle 301 on the pull-out box 3. The magnesium rod 1 is replaced and the pull-out box 3 is cleaned. The movable covers 9 automatically return to their original position under the action of the spring piece 10. After replacement, manually press down the spring covers 7 on both sides of the magnesium rod body structure so that the outer end of the spring cover 7 is flush with the side wall of the bracket 2, and insert the magnesium rod body structure into the base 11. After the outer end of the spring cover 7 is aligned with the position on the pressure plate 8 that accommodates the outer end of the spring cover 7, the outer end of the spring cover 7 will automatically pop out of the bracket 2 under the action of the elastic element 6 and insert into the pressure plate 8 of the disassembly assistance structure, so as to realize the snap-fit ​​between the magnesium rod body structure and the disassembly assistance structure and complete the installation.

[0084] Secondly, this disclosure also provides a water heater including the aforementioned magnesium rod mechanism.

[0085] In this embodiment of the disclosure, such as Figure 5 As shown, the magnesium rod mechanism is installed at the bottom of the water heater 13. The water heater can be an electric water heater, a gas water heater, or other types of water heaters.
