[0033] Reference below Figure 1-Figure 5 Description According to the inner liner structure 100 of the embodiment of the utility model, the temperature sensor 4 can be tightly installed on the inner liner body 1 by setting the elastic member 3 and the fixing buckle 2, which can improve the output reliability of the temperature sensor 4, and the temperature sensor 4 is easy to install and facilitate disassembly and replacement.

[0034] like Figure 1-Figure 5 As shown, the inner liner structure 100 according to the embodiment of the utility model includes: an inner liner body 1, a fixing buckle 2 and an elastic member 3.

[0035] The inner tank body 1 can be used to store fluid media, such as storing liquid substances such as water or storing gas substances such as hydrogen. Specifically, the inner tank structure 100 can be applied to a water heater, so that the inner tank body 1 can be used to store hot water, and the water stored in the inner tank body 1 can be heated by a heating rod. At the same time, a temperature sensor 4 can be installed outside the inner tank body 1. The temperature sensor 4 can detect the change in the water temperature in the inner tank body 1, and thus feed back the temperature to the control center, so that the water heater can stably provide hot water for users to use.

[0036] The fixing buckle 2 is connected to the outer peripheral wall of the inner liner body 1, and the fixing buckle 2 and the inner liner body 1 define a plug-in cavity 21, and the plug-in cavity 21 is used to plug the temperature sensor 4. In other words, the fixing buckle 2 is connected to the outer peripheral wall of the inner liner body 1, and one side of the fixing buckle 2 is open and defines a certain installation space with the outer peripheral wall of the inner liner body 1, that is, forming the plug-in cavity 21, so that the temperature sensor 4 can be plugged in.

[0037] Furthermore, the elastic member 3 is installed on the fixing buckle 2, and the elastic member 3 is suitable for elastically pressing against the temperature sensor 4 so that the temperature sensor 4 is kept in the plug-in cavity 21. The elastic member 3 can be installed in the plug-in cavity 21 first, and the temperature sensor 4 is plugged between the elastic member 3 and the inner tank body 1, or the elastic member 3 and the temperature sensor 4 are installed in the plug-in cavity 21 at the same time, and the elastic force of the elastic member 3 is used to make the elastic member 3 press against the temperature sensor 4 on one side and press against the fixing buckle 2 on the other side, so that the temperature sensor 4 presses against the outer peripheral wall of the inner tank body 1 and is kept in the plug-in cavity 21, so as to achieve the limiting effect on the temperature sensor 4 and prevent the temperature sensor 4 from shaking or falling off spontaneously. Thus, the temperature sensor 4 can be pressed against the inner tank body 1 of the water tank by the elastic member 3 to achieve the installation of the temperature sensor 4, and in the process of installing and removing the temperature sensor 4, it is not necessary to use screws and other connectors, so the connection efficiency is higher and the disassembly is more convenient.

[0038] Among them, the temperature sensor 4 is plugged into the plug-in cavity 21, and the wiring harness connected to the temperature sensor 4 is more convenient to connect, which is conducive to improving the reliability of the output of the temperature sensor 4. At the same time, the fixing buckle 2 can be pre-installed on the outer wall of the inner tank body 1, that is, there is no need to set screws and other connecting parts to penetrate the outer wall of the inner tank body 1, and then there is no need to perform a sealing operation on the position where the temperature sensor 4 is set on the inner tank body 1, which is conducive to ensuring the sealing effect of the inner tank body 1.

[0039] According to the inner liner structure 100 of the utility model, a plug-in cavity 21 is defined by the fixing buckle 2 and the outer peripheral wall of the inner liner body 1 to form an installation space for the temperature sensor 4, so that the temperature sensor 4 can be plugged into the plug-in cavity 21, and the temperature sensor 4 can be pressed against the outer peripheral wall of the inner liner body 1 by the elastic member 3 to fix the temperature sensor 4, making the installation and disassembly of the elastic member 3 more convenient, thereby facilitating the installation and disassembly of the temperature sensor 4, and the installation of the temperature sensor 4 by plug-in fixing can improve the reliability of the output line of the temperature sensor 4.

[0040] In some embodiments, the elastic member 3 is formed with a card interface 31, and the elastic member 3 is configured to be connected to the fixing buckle 2 at the card interface 31, that is, a card interface 31 is formed at one end of the elastic member 3, and the opening size of the card interface 31 can be set to be larger than the thickness size of the fixing buckle 2, so that the elastic member 3 can be smoothly connected to the fixing buckle 2 at the card interface 31. The structure is simple and the installation is convenient, which is conducive to improving the installation convenience of the elastic member 3 and the fixing buckle 2.

[0041] Specifically, Figure 4 As shown, the right end of the elastic member 3 is provided with a card interface 31, that is, the elastic member 3 may include two parts, the two parts are respectively located on both sides of the card interface 31, and one end of the card interface 31 is open. In this way, when the elastic member 3 is actually installed, as shown in Figure 2, a part of the elastic member 3 is extended into the plug-in cavity 21 from the open end of the card interface 31, and the other part of the elastic member 3 is extended into the outside of the fixing buckle 2, so that the inner wall of the card interface 31 is pressed and matched with the upper edge of the fixing buckle 2, that is, the upper edge of the fixing buckle 2 can be extended into the card interface 31 to limit the two parts of the elastic member 3, so that the elastic member 3 can be installed in the fixing buckle 2 by card connection. Therefore, when the elastic member 3 is installed in the fixing buckle 2, the two can be carded and matched, and the installation efficiency is higher. When disassembling, the elastic member 3 can be separated from the fixing buckle 2 from the card interface 31, and the disassembly is also easier.

[0042] In some embodiments, the elastic member 3 includes a snap-fitting portion 32 and an elastic pressing portion 33, a snap-fitting portion 32 and an elastic pressing portion 33 defining a snap-fitting interface 31, the snap-fitting portion 32 snaps and presses against the outer side of the fixing buckle 2, the elastic pressing portion 33 extends into the plug-in cavity 21 and is suitable for elastically pressing between the fixing buckle 2 and the temperature sensor 4.

[0043] Specifically, Figure 4 As shown in FIG. 1 , the upper part of the elastic member 3 is a clamping portion 32, and the lower part is an elastic pressing portion 33. The clamping portion 32 and the elastic pressing portion 33 are arranged opposite to each other, and the clamping portion 32 and the elastic pressing portion 33 are connected to define a clamping interface 31. The length of the clamping portion 32 is smaller than the length of the elastic pressing portion 33, so that it is convenient to install and remove the elastic member 3 from the outside. When the elastic member 3 is actually installed, as shown in FIG. Figure 2 and Figure 3As shown, the elastic member 3 is installed and snap-fitted with the fixing buckle 2 at the card interface 31, so that the snap-fitting portion 32 is snap-fitted and pressed against the outer wall of the fixing buckle 2, and the elastic pressing portion 33 extends into the plug-in cavity 21, and one side of the elastic pressing portion 33 presses against the inner wall of the fixing buckle 2, and the other side presses against the temperature sensor 4, thereby making the elastic pressing portion 33 press between the fixing buckle 2 and the temperature sensor 4, wherein the elastic pressing portion 33 is constructed to be elastically deformable, that is, when the elastic pressing portion 33 presses between the fixing buckle 2 and the temperature sensor 4, it can utilize its own elastic deformation to achieve elastic pressing between the fixing buckle 2 and the temperature sensor 4, thereby facilitating the elastic force to keep the fixing buckle 2 and the temperature sensor 4 in a relatively stable position, that is, to stably press the temperature sensor 4 into the fixing buckle 2.

[0044] Thus, the snap-fitting with the fixing buckle 2 can be realized on the outside of the fixing buckle 2 by the snap-fitting portion 32, and at the same time, the temperature sensor 4 can be installed and fixed inside the fixing buckle 2 by utilizing the elastic deformation force through the elastic pressing portion 33. The structure is simple and the installation process is easy to realize.

[0045] In some embodiments, the elastic pressing portion 33 includes a first inner segment 331, a second inner segment 332 and a third inner segment 333. The first inner segment 331 is connected to the clamping portion 32. The first inner segment 331, the second inner segment 332 and the third inner segment 333 are bent in sequence and connected, that is, the elastic pressing portion 33 is formed by three inner segments that are bent in sequence to form a certain angle and connected.

[0046] Specifically, Figure 4 As shown, the elastic pressing portion 33 is composed of three inner sections, one end of the first inner section 331 is connected to the clamping portion 32, and the clamping interface 31 is formed between the first inner section 331 and the clamping portion 32, the other end of the first inner section 331 is connected to the second inner section 332, the first inner section 331 is inclined at a certain angle in the direction away from the clamping portion 32, and at the same time, the second inner section 332 is inclined at a certain angle from the other end connected to the first inner section 331 to the end away from the first inner section 331 in the direction close to the clamping portion 32, so that the ends of the first inner section 331 and the second inner section 332 are bent and connected to form an obtuse angle protruding in the direction away from the clamping portion 32. And the third inner section 333 is bent and connected to the end of the second inner section 332 away from the first inner section 331, and the connection between the third inner section 333 and the second inner section 332 also forms an obtuse angle, and the obtuse angle at this position is opposite to the protruding direction of the obtuse angle at the connection between the first inner section 331 and the second inner section 332.

[0047] Therefore, a first clamping protrusion 334 is formed at the connection between the first inner section 331 and the second inner section 332, and the first clamping protrusion 334 is used to press the temperature sensor 4. A second clamping protrusion 335 is formed at the connection between the second inner section 332 and the third inner section 333, and the second clamping protrusion 335 is used to press the inner wall of the fixing buckle 2. That is to say, when installing the temperature sensor 4, the elastic pressing part 33 can be first extended into the plug-in cavity 21, and then the temperature sensor 4 can be inserted between the elastic pressing part 33 and the outer peripheral wall of the inner tank body 1, so that the first clamping protrusion 334 is pressed against the temperature sensor 4, and the second clamping protrusion 335 is pressed against the inner wall of the fixing buckle 2. As a result, the elastic pressing part 33 presses the temperature sensor 4 between the inner wall of the fixing buckle 2 and the outer peripheral wall of the inner tank body 1, reducing the gap between the temperature sensor 4 and the inner tank body 1, making the temperature sensor 4 fit closely with the inner tank body 1, and realizing that the temperature sensor 4 is pressed tightly against the inner tank body 1, which can realize the stable installation of the temperature sensor 4, and is conducive to reducing the gap between the temperature sensor 4 and the inner tank body 1, thereby improving the accuracy of temperature detection.

[0048] Specifically, Figure 4 As shown, a first pressing protrusion 334 is formed at the connection between the first inner section 331 and the second inner section 332, and a second pressing protrusion 335 is formed at the connection between the second inner section 332 and the third inner section 333. The protruding directions of the first pressing protrusion 334 and the second pressing protrusion 335 are opposite. When the elastic member 3 is installed, as shown in FIG. Figure 3 As shown, the first clamping protrusion 334 protrudes toward the temperature sensor 4 and presses on the temperature sensor 4, and the second clamping protrusion 335 protrudes toward the inner wall of the fixing buckle 2 and presses on the inner wall of the fixing buckle 2. The two clamping protrusions fix two positions respectively, so that one side of the temperature sensor 4 presses against the first clamping protrusion 334 of the elastic member 3, and the other side of the temperature sensor 4 presses against the outer wall of the inner tank body 1, so that the position of the temperature sensor 4 in the plug-in cavity 21 is fixed, and the temperature sensor 4 is clamped and fixed. The structure is simple and the installation is convenient.

[0049] In some embodiments, the extension length of the second inner section 332 is greater than the extension length of the third inner section 333 and less than the extension length of the first inner section 331. Figure 4As shown, the extension length of the first inner section 331 is the longest, and the extension length of the first inner section 331 is greater than the extension length of the clamping portion 32. In the specific structure, the extension length of the first inner section 331 can be set to be twice the extension length of the clamping portion 32, and the extension length of the second inner section 332 is shorter than the extension length of the first inner section 331, or the extension length of the second section can also be set to be longer than the extension length of the first inner section 331, and the extension length of the third inner section 333 is the shortest. Since the angle between the first inner section 331 and the second inner section 332 is large, the first inner section 331 and the second inner section 332 can be set to have a longer length extending along the installation direction of the temperature sensor 4, thereby allowing the elastic pressing portion 33 to extend into the plug-in cavity 21. The first clamping protrusion 334 can press against the middle position of the temperature sensor 4 in the plug-in cavity 21, and the second clamping protrusion 335 can press against the inner wall of the fixing buckle 2 near the edge position, and the two clamping protrusions are separated by a certain distance to increase the stability of fixing the temperature sensor 4.

[0050] Specifically, Figure 3 As shown, after the elastic member 3 is installed between the temperature sensor 4 and the fixing buckle 2, the first pressing protrusion 334 presses against the middle position of the temperature sensor 4, and the second pressing protrusion 335 presses against the inner wall of the fixing buckle 2 near the edge, so that the temperature sensor 4 is pressed between the outer peripheral wall of the inner tank body 1 and the elastic member 3 as a whole and stably. It should be noted that the extension length of the first inner section 331, the extension length of the second inner section 332, and the extension length of the third inner section 333 are not limited to those described in this embodiment, and can be flexibly set according to actual needs and space size.

[0051] In some embodiments, the clamping portion 32 includes a first outer segment 321 and a second outer segment 322, the first outer segment 321 is connected to the elastic pressing portion 33, the first outer segment 321 and the second outer segment 322 are bent and connected, and a third clamping protrusion 323 for pressing the outer wall of the fixing buckle 2 is formed at the connection between the first outer segment 321 and the second outer segment 322.

[0052] Specifically, Figure 4As shown, the clamping portion 32 is composed of two outer sections, a first outer section 321 and a second outer section 322. One end of the first outer section 321 is connected to the elastic pressing portion 33, and the other end is connected to the second outer section 322. The first outer section 321 and the second outer section 322 are connected at a certain angle along the installation direction of the temperature sensor 4. A third clamping protrusion 323 protruding toward the first inner section 331 is formed at the connection where the first outer section 321 and the second outer section 322 are bent and connected. When the elastic member 3 is actually installed, the clamping portion 32 extends into the outside of the fixing buckle 2, and the third clamping protrusion 323 presses on the outer wall of the fixing buckle 2. As a result, the elastic member 3 is pressed between the inner and outer walls of the fixing buckle 2 and the temperature sensor 4, and the elastic member 3 can be taken out through the second outer section 322, so that the temperature sensor 4 can be disassembled and replaced, and the installation and disassembly are convenient.

[0053] In some embodiments, an arc segment 34 is connected between the clamping portion 32 and the elastic pressing portion 33 , so that the clamping portion 32 and the elastic pressing portion 33 are connected as a whole and are arranged opposite to each other.

[0054] Specifically, Figure 4 As shown, the first outer section 321 of the clamping part 32 and the first inner section 331 of the elastic pressing part 33 are connected through the arc section 34, so that the clamping part 32 and the elastic pressing part 33 are connected to form an integral elastic member 3 structure, and the clamping part 32 and the elastic pressing part 33 can be arranged relative to each other by setting the arc section 34 transition. Figure 1 and Figure 2 As shown, when the elastic member 3 is installed to press the temperature sensor 4, the clamping portion 32 can be pressed against the outer wall of the fixing buckle 2, the elastic pressing portion 33 extends into the plug-in cavity 21 and presses between the inner wall of the fixing buckle 2 and the temperature sensor 4, and the arc segment 34 is sleeved at the upper edge of the fixing buckle 2.

[0055] In some embodiments, the fixing buckle 2 includes a main body 22 and two flange portions 23. The main body 22 is formed with a plug-in groove 221 open on one side. The two flange portions 23 are respectively connected to the two sides of the main body 22 and are respectively connected to the outer peripheral wall of the inner liner body 1, so that the main body 22 and the inner liner body 1 define a plug-in cavity 21 at the plug-in groove 221.

[0056] Specifically, Figure 5As shown, the fixing buckle 2 includes a main body 22 in the middle and two flanges 23 located on both sides of the main body 22. The two flanges 23 can be constructed to have a fitting plane, and the two flanges 23 are respectively connected to both sides of the main body 22, and the length is the same as that of the main body 22. The main body 22 can be constructed as a hollow semi-cylindrical structure, and one side is open to form a plug-in slot 221, wherein the thickness of the flange 23 can be set to be the same as that of the main body 22, that is, the main body 22 and the two flanges 23 can be integrally formed. Figure 2 As shown, when the fixing buckle 2 is actually installed on the inner liner body 1, the two flange portions 23 are tightly connected to the outer peripheral wall of the inner liner body 1, and the open side of the plug-in groove 221 of the main body 22 faces the outer peripheral wall of the inner liner body 1, and a certain space is formed between the outer peripheral wall of the inner liner body 1, that is, the plug-in cavity 21 is defined, so that the temperature sensor 4 can be inserted into the plug-in cavity 21.

[0057] In some embodiments, the insertion cavity 21 is configured to pass through the fixing buckle 2 in the up-down direction. Figure 1 and Figure 2 As shown, the plug-in cavity 21 passes through the main body 22 of the fixing buckle 2 along the up-down direction in the figure, and the direction of the plug-in cavity 21 is the same as the axial direction of the inner tank body 1, wherein the space size of the plug-in cavity 21 is larger than the size of the temperature sensor 4, thereby enabling the temperature sensor 4 to be installed in the plug-in cavity 21 through the elastic member 3 along the up-down direction in the figure.

[0058] In other words, both the upper and lower ends of the plug-in cavity 21 can be set as open ends. Therefore, during actual installation, the temperature sensor 4 can be plugged into the plug-in cavity 21 from the upper end and elastically pre-tightened by the elastic member 3, or it can be plugged into the plug-in cavity 21 from the lower end and elastically pre-tightened by the elastic member 3. The plug-in method is flexible and optional.

[0059] The utility model also provides a water heater.

Among them, the plug-in cavity 21 is defined by the fixing buckle 2 and the outer peripheral wall of the liner body 1, forming an installation space for the temperature sensor 4, so that the temperature sensor 4 can be plugged into the plug-in cavity 21, and the temperature sensor 4 can be pressed against the outer peripheral wall of the liner body 1 by the elastic member 3, and the temperature sensor 4 is fixed, which can improve the reliability of the outlet of the temperature sensor 4, ensure the sealing effect of the liner body 1, and the elastic member 3 is easy to install and disassemble, thereby facilitating the installation and disassembly of the temperature sensor 4.
