[0028] Reference below Figure 1-Figure 3 The inner tank structure 100 according to the embodiment of the utility model is described. The reaction rod 12 and the electric heating element 13 are staggered in the accommodating cavity 11 to avoid interference between the two, thereby ensuring the reliability of the operation of the reaction rod 12 and the electric heating element 13.

[0029] like Figure 1 As shown, an inner liner structure 100 according to an embodiment of the present invention includes: an inner liner body 1, a reaction rod 12 and an electric heating element 13.

[0030] A receiving cavity 11 is formed in the inner tank body 1. Specifically, the inner tank body 1 is a cylindrical structure, and a receiving cavity 11 is formed in the inner tank body 1, that is, the receiving cavity 11 is also a cylindrical cavity, and the receiving cavity 11 can be used to receive a fluid medium, that is, it can be used to receive a liquid substance or a gas substance. In the utility model, the inner tank structure 100 can be applied to a water heater, that is, the receiving cavity 11 can be used to receive hot water.

[0031] The reaction rod 12 is installed in the accommodating chamber 11, and the reaction rod 12 extends in the accommodating chamber 11 along the first direction. Specifically, the reaction rod 12 is arranged in the accommodating chamber 11, and the reaction rod 12 is used to combine with oxygen ions in the water, so that the water in the accommodating chamber 11 is oxygen-free water, which will not cause corrosion to other components in the accommodating chamber 11 and the inner wall of the accommodating chamber 11, and plays a role in protecting the water tank, and the reaction rod 12 is installed in the accommodating chamber 11, so that it is relatively fixed with the accommodating chamber 11, so as to avoid its movement in the accommodating chamber 11 and collision with the liner body 1 or other components in the liner body 1, causing damage and failure of the liner body 1 or other components in the liner body 1. And, the reaction rod 12 is arranged to extend along the first direction, and the first direction can be the axial direction of the accommodating chamber 11, that is, the reaction rod 12 is arranged to extend along the axial direction of the accommodating chamber 11, or the first direction can be set to the radial direction of the accommodating chamber 11, that is, the reaction rod 12 is arranged to extend along the radial direction of the accommodating chamber 11.

[0032] It should be noted that the reaction rod 12 can be constructed as a magnesium rod, which can release magnesium ions into water and combine with oxygen ions in the water.

[0033] The electric heating element 13 is installed on the inner container body 1 . The electric heating element 13 extends into the accommodating cavity 11 and extends along the second direction in the accommodating cavity 11 . The electric heating element 13 and the reaction rod 12 are staggered in distribution.

[0034] Specifically, the electric heating element 13 can convert electric energy into heat energy to heat the water in the accommodating chamber 11. The electric heating element 13 is set to extend along the second direction in the accommodating chamber 11, that is, the electric heating element 13 can extend along the radial direction of the accommodating chamber 11. When the first direction is the axial direction of the accommodating chamber 11, the second direction can be set to be staggered with the first direction, such as the second direction is set to be along the radial direction of the accommodating chamber 11 and inclined at a certain angle, or when the first direction is the radial direction of the accommodating chamber 11, the second direction can also be set to be along the axial direction of the accommodating chamber and inclined at a certain angle, so that the reaction rod 12 and the electric heating element 13 can be extended in different directions, and thus the reaction rod 12 and the electric heating element 13 are staggered inside the accommodating chamber 11, so that the two can be spaced apart to avoid interference, and the reliability of the reaction rod 12 reacting with water and the electric heating element 13 heating water can be further ensured.

[0035] Thus, by forming a receiving chamber 11 in the inner liner body 1 to store water, and arranging a reaction rod 12 in the receiving chamber 11 to react with water, damage to the inner liner body 1 or other components in the inner liner body 1 is avoided. At the same time, an electric heating element 13 is installed on the inner liner body 1, and the electric heating element 13 is extended to the inside of the receiving chamber 11 to heat the water, and the reaction rod 12 and the electric heating element 13 are extended in different directions in the receiving chamber 11, and the two are staggered to avoid interference between the two. Thus, the reaction rod 12 and the electric heating element 13 are arranged to extend in different directions, and the reaction rod 12 can be arranged to have a larger extension length along the first direction, so that the reaction rod 12 has a larger reaction area along the first direction, and the reaction effect of the reaction rod 12 in the receiving chamber 11 is enhanced, thereby increasing the protective effect of the reaction rod 12 on the receiving chamber 11. At the same time, the electric heating element 13 is configured to have a larger extension length along the second direction so that the electric heating element 13 has a larger heating surface area along the second direction, thereby enhancing the heating surface of the electric heating element 13 in the accommodating cavity 11 and thereby increasing the heating effect of the electric heating element 13.

[0036] According to the inner tank structure 100 of the embodiment of the utility model, the water in the accommodating chamber 11 is heated by setting an electric heating element 13 to meet the user's needs, and a reaction rod 12 is set in the accommodating chamber 11 to react with water, so as to protect the inner tank body 1 and other components in the inner tank body 1, and the reaction rod 12 and the electric heating element 13 are staggered to avoid interference between the two, thereby improving the reliability of the operation of the reaction rod 12 and the electric heating element 13.

[0037] In some embodiments, the reaction rod 12 is connected to the inner end surface of the accommodating cavity 11 and is extended along the axial direction of the liner body 1 .

[0038] Specifically, by connecting the reaction rod 12 to the inner end surface of the accommodating chamber 11, the reaction rod 12 can be connected to the inner liner body 1, and the reaction rod 12 and the inner liner body 1 can be fixedly connected to improve the connection strength between the two. It can also prevent the reaction rod 12 from shaking or moving in the accommodating chamber 11, colliding with or interfering with the inner liner body 1 or other components in the inner liner body 1, and preventing the reaction rod 12, the inner liner body 1 or other components in the inner liner body 1 from being damaged and failing. And by extending the reaction rod 12 along the axial direction of the inner liner body 1, that is, extending it along the length direction of the inner liner body 1, the length of the reaction rod 12 can be increased, and the service life of the reaction rod 12 can be extended.

[0039] It should be noted that in Figure 1 and Figure 2 In the illustrated embodiment, the reaction rod 12 is connected to the inner end surface of the accommodating chamber 11 and connected by bolts 18 to improve the connection strength between the reaction rod 12 and the inner liner body 1. In addition, the reaction rod 12 extends along a first direction in the accommodating chamber 11 and extends along the axial direction of the inner liner body 1, that is, the first direction is the axial direction of the inner liner body 1.

[0040] The electric heating element 13 is connected to the peripheral wall of the inner pot body 1 , and a radial line of the inner pot body 1 passing through the electric heating element 13 forms an angle with the extension direction of the electric heating element 13 .

[0041] Specifically, the electric heating element 13 is connected to the peripheral wall of the inner pot body 1, and the electric heating element 13 can be installed on the inner pot body 1. The electric heating element 13 and the inner pot body 1 can be fixedly connected to improve the connection strength between the two, and the electric heating element 13 can be prevented from shaking or moving in the inner pot body 1, colliding or interfering with the inner pot body 1 or other components in the inner pot body 1, and preventing the electric heating element 13, the inner pot body 1 or other components in the inner pot body 1 from being damaged and failing. And there is an angle between the radial line of the inner pot body 1 passing through the electric heating element 13 and the extension direction of the electric heating element 13, that is, the electric heating element 13 extends along a plane parallel to the inner end surface of the inner pot body 1 and does not pass through the center of the plane, so as to avoid interference between the electric heating element 13 and the reaction rod 12, causing the reaction rod 12 or the electric heating element 13 to fail, so as to improve the reliability of their respective work.

[0042] In some embodiments, the electric heating element 13 includes a heating portion 131 and a mounting portion 132. The heating portion 131 extends into the accommodating cavity 11, and the mounting portion 132 is connected to the end of the heating portion 131. The peripheral wall of the inner tank body 1 is provided with a mounting hole 14, and the mounting portion 132 is detachably mounted at the mounting hole 14. Figure 3 As shown, the heating portion 131 can be configured as a heating tube, and the mounting portion 132 can be configured as a mounting block, which can be threadedly matched with the mounting hole 14, or detachably connected by other means.

[0043] Specifically, the electric heating element 13 includes two parts, namely a heating part 131 and a mounting part 132. The heating part 131 can convert electrical energy into thermal energy. The heating part 131 is extended into the accommodating cavity 11, and the water in the accommodating cavity 11 can be heated by the heating part 131. The mounting part 132 is connected to the end of the heating part 131, and the electric heating element 13 can be installed at the end of the heating part 131. The electric heating element 13 can be connected to the inner pot body 1 here, and the heating part 131 can be placed entirely inside the accommodating cavity 11, thereby increasing the contact area between the electric heating element 13 and the water, thereby improving the efficiency of heating the water. A mounting hole 14 is provided on the peripheral wall of the inner pot body 1, so that the electric heating element 13 is connected to the inner pot body 1 through the cooperation between the mounting hole 14 and the mounting portion 132, and the mounting portion 132 and the mounting hole 14 are detachably connected, so that the mounting portion 132 can be flexibly installed and removed relative to the mounting hole 14, so that the electric heating element 13 can be replaced when it is damaged and fails.

[0044] Furthermore, when installing the electric heating element 13, the mounting portion 132 can be passed through the mounting hole 14, and the mounting portion 132 can be connected to the mounting hole 14, so that the electric heating element 13 can be installed on the inner tank body 1, and when the electric heating element 13 is damaged, the damaged electric heating element 13 can be removed from the inner tank body 1, and then a new electric heating element 13 can be reinstalled. It should be noted that the heating portion 131 and the mounting portion 132 can be fixedly connected, or the two can be directly constructed as one, so as to improve the connection strength between the two.

[0045] In some embodiments, the extension length of the heating portion 131 is greater than the radius of the accommodating cavity 11 .

[0046] Specifically, Figure 3 As shown, the heating part 131 of the electric heating element 13 is located in the accommodating cavity 11, and is in direct contact with the water in the accommodating cavity 11, converting its own electrical energy into thermal energy to heat the water. By setting the extension length of the heating part 131 to be greater than the radius of the accommodating cavity 11, the length of the heating part 131 can be increased, and then the contact area between the heating part 131 and the water can be increased, thereby improving the heating efficiency, shortening the user's waiting time, and improving the user experience.

[0047] In some embodiments, an axial direction of the mounting hole 14 forms an angle with a radial line of the liner body 1 passing through the mounting hole 14 .

[0048] Specifically, the electric heating element 13 is installed on the inner tank body 1 through the cooperation between the mounting hole 14 and the mounting portion 132, that is, the position of the mounting hole 14 can determine the position of the electric heating element 13, and there is an angle between the axial direction of the mounting hole 14 and the radial line of the inner tank body 1 passing through the mounting hole 14, that is, there is an angle between the axial direction of the electric heating element 13 and the radial line passing through the mounting hole 14, which can avoid interference between the heating portion 131 of the electric heating element 13 and the reaction rod 12, causing failure of the reaction rod 12 or the electric heating element 13, so as to improve the reliability of the operation of the reaction rod 12 and the electric heating element 13.

[0049] In some embodiments, the mounting hole 14 is configured as a threaded hole, the mounting portion 132 is formed with an external thread and threadedly matched with the mounting hole 14, and the axial direction of the threaded hole is the same as the extension direction of the heating portion 131. In other words, the mounting hole 14 and the mounting portion 132 can be connected by the threaded hole and the external thread.

[0050] Specifically, the mounting hole 14 is constructed as a threaded hole, and the outer peripheral wall of the mounting portion 132 is constructed as an external thread, so that the mounting hole 14 and the mounting portion 132 are connected by the threaded connection between the threaded hole and the external thread, and the electric heating element 13 can be installed on the inner tank body 1, and the connection method is simple and reliable. At the same time, the mounting hole 14 is threadedly connected to the mounting portion 132, and the mounting portion 132 is connected to the heating portion 131, that is, the axial direction of the mounting hole 14 coincides with the axial direction of the mounting portion 132, and the axial direction of the mounting portion 132 is the same as the extension direction of the heating portion 131, that is, the axial direction of the threaded hole is the same as the extension direction of the heating portion 131, that is, the setting position of the threaded hole on the inner tank body 1 can be controlled to control the extension direction of the heating portion 131 in the accommodating cavity 11, and then the extension direction of the heating portion 131 can be controlled to avoid interference between the electric heating element 13 and the reaction rod 12, so as to improve the reliability of the operation of the electric heating element 13 and the reaction rod 12.

[0051] In some embodiments, a sealing groove 141 is formed at the mounting hole 14, a sealing element 142 is disposed in the sealing groove 141, and a limiting step 1321 is disposed at the mounting portion 132. The limiting step 1321 is suitable for pressing against the sealing element 142 after the mounting portion 132 and the mounting hole 14 are screwed together.

[0052] Specifically, the mounting hole 14 is connected and cooperated with the mounting portion 132, and a sealing groove 141 is formed at the mounting hole 14. A sealing element 142 is arranged in the sealing groove 141. The sealing element 142 can be used to seal the gap between the mounting hole 14 and the mounting portion 132 to reduce the probability of water in the accommodating chamber 11 flowing out of the gap between the mounting hole 14 and the mounting portion 132, and a limiting step 1321 is arranged on the mounting portion 132. The limiting step 1321 can be pressed against the sealing element 142 to limit the installation position of the mounting portion 132, and then the installation position of the electric heating element 13 can be limited to avoid the heating portion 131 extending into the accommodating chamber 11. The shorter the length, the lower the heating efficiency, and the interference between the electric heating element 13 and the reaction rod 12 can be avoided, causing damage and failure of both.

[0053] In such Figure 3 In the illustrated embodiment, the mounting hole 14 is configured to extend outward from the outer peripheral wall of the liner body 1, and an angle exists between the axial direction of the mounting hole 14 and a radial line of the liner body 1 passing through the mounting hole 14, so that the electric heating element 13 and the reaction rod 12 can be staggered to avoid interference between the electric heating element 13 and the reaction rod 12, thereby improving the reliability of their respective operations, and the limiting step 1321 can press the sealing element 142 on the side facing the liner body 1 to limit the position of the mounting portion 132.

[0054] It should be noted that the sealing element 142 can be made of elastic materials such as rubber.

[0055] In some embodiments, the angle between the radial line of the electric heating element 13 of the inner pot body 1 and the extension direction of the electric heating element 13 is less than or equal to 45°. In other words, the radial line of the electric heating element 13 of the inner pot body 1 is different from the extension direction of the electric heating element 13.

[0056] Specifically, the radial line of the electric heating element 13 of the inner pot body 1 is set to be different from the extension direction of the electric heating element 13, which can avoid interference between the heating part 131 of the electric heating element 13 and the reaction rod 12, causing damage and failure of both, and the angle between the two is set to be less than or equal to 45°, so that the angle between the extension direction of the electric heating element 13 and the radial line of the electric heating element 13 of the inner pot body 1 can be as small as possible while ensuring that the two do not interfere with each other, and then the length of the heating part 131 of the electric heating element 13 can be made as long as possible, so as to improve the efficiency of heating water, reduce the waiting time of users, and improve user experience.

[0057] In some embodiments, the axis of the inner container body 1 coincides with the axis of the reaction rod 12 , and the electric heating element 13 and the reaction rod 12 are vertically distributed in the accommodation space.

[0058] Specifically, the axis of the inner liner body 1 coincides with the axis of the reaction rod 12, that is, the reaction rod 12 is installed at the center position of the end of the inner liner body 1, so that the reaction rod 12 reacts with water and protects the inner liner body 1 and other components inside the inner liner body 1, and the electric heating element 13 is arranged on a plane parallel to the end face of the inner liner body 1, that is, the electric heating element 13 and the reaction rod 12 are spatially vertically distributed in the accommodating cavity 11, so that the electric heating element 13 and the reaction rod 12 can be located in different directions in the inner liner body 1, and an angle is set between the extension direction of the electric heating element 13 and the radial line of the inner liner body 1 through the electric heating element 13, so as to avoid interference between the electric heating element 13 and the reaction rod 12, thereby improving the reliability of their respective work.

[0059] And, it should be noted that if Figure 2 As shown, a water inlet valve 15 and a water outlet valve 16 are also provided on the peripheral wall of the inner tank body 1. The water inlet valve 15 extends to the interior of the accommodating chamber 11 to inject water into the accommodating chamber 11. The water outlet valve 16 is used to allow water to flow out from it for the convenience of users. In addition, a sewage valve 17 is also provided on the peripheral wall of the inner tank body 1 to discharge impurities in the accommodating chamber 11 from it to ensure the cleanliness and hygiene of the water quality.

[0060] The utility model also provides a hot water tank.

The water in the accommodating chamber 11 is heated by arranging the electric heating element 13 to meet the needs of users, and the reaction rod 12 is arranged in the accommodating chamber 11 to react with the water, so as to protect the inner tank body 1 and other components in the inner tank body 1, and an angle is arranged between the radial line of the electric heating element 13 of the inner tank body 1 and the extension direction of the electric heating element 13 to avoid interference between the two, thereby improving the reliability of the reaction rod 12 and the electric heating element 13 working separately.
