[0065] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0066] Reference below Figures 1-13 The thermal insulation assembly 10 for the joint device 20 according to an embodiment of the present application is described. The thermal insulation assembly 10 includes an insulation tube 11 and an insulation member 12. The insulation tube 11 is formed with a first channel 111 arranged axially therethrough. The insulation member 12 includes a plurality of insulation plates 121. The insulation plates 121 are at least partially radially arranged in the first channel 111. The insulation member 12 and / or the insulation tube 11 form a limiting portion 118. The limiting portion 118 is suitable for limiting the radial movement of the insulation member 12 relative to the insulation tube 11.

[0067] like Figure 1-Figure 3 As shown, specifically, the insulation assembly 10 may include an insulation tube 11 and an insulation part 12. A first channel 111 may be formed in the insulation tube 11. The first channel 111 may be arranged to penetrate the insulation tube 11 in the axial direction. The first channel 111 may be used for liquid flow. In some embodiments, the insulation tube 11 may be arranged at the joint at the water inlet end or the water outlet end of the water heater 30. The insulation tube 11 may reduce the heat inside the water tank 31 when the water heater 30 is statically insulated, and perform heat exchange with the external environment through the water pipe joint 21.

[0068] like Figure 3 and Figure 4 As shown, the thermal insulation member 12 may include a thermal insulation sheet 121. The thermal insulation sheet 121 may be constructed in plurality. The plurality of thermal insulation sheets 121 may be spaced apart in the axial direction or in the extension direction of the thermal insulation member 12, wherein the axial direction may be the axial direction of the thermal insulation tube 11. In some embodiments, the extension direction of the thermal insulation member 12 may be the same direction as the axial direction of the thermal insulation tube 11.

[0069] like Figure 2 and Figure 3 As shown, at least a portion of the thermal insulation sheet 121 can be radially arranged in the first channel 111. It should be noted that the material of the thermal insulation sheet 121 is relatively soft. When water flows through the first channel 111, the thermal insulation sheet 121 can achieve the circulation of water by bending. When the water heater 30 is statically insulated, the thermal insulation sheet 121 can reduce the heat exchanged between the inside of the water tank 31 and the low-temperature water in the first channel 111, thereby reducing the heat loss of the water heater 30 during the insulation period.

[0070] Furthermore, a limiting portion 118 can be formed on the thermal insulation member 12 or the thermal insulation tube 11, and the limiting portion 118 can limit the movement of the thermal insulation member 12 relative to the thermal insulation tube 11. For example, a limiting portion 118 can be formed on the thermal insulation member 12, and the limiting portion 118 can cooperate with the thermal insulation tube 11 to limit the relative radial movement between the thermal insulation member 12 and the thermal insulation tube 11, or a limiting portion 118 can be formed on the thermal insulation tube 11, and the limiting portion 118 can cooperate with the thermal insulation member 12 to limit the relative radial movement between the thermal insulation tube 11 and the thermal insulation member 12. In some embodiments, a limiting portion 118 can be formed on both the thermal insulation member 12 and the thermal insulation tube 11, and the relative radial movement between the thermal insulation member 12 and the thermal insulation tube 11 is limited by the limiting portion 118, thereby ensuring the fitting strength and fitting effect between the thermal insulation member 12 and the thermal insulation tube 11, so that the thermal insulation member 12 can effectively achieve the thermal insulation function, thereby improving the service life of the thermal insulation assembly 10.

[0071] In short, the thermal insulation assembly 10 of the embodiment of the present application includes an insulation tube 11 and an insulation member 12. The insulation member 12 may be provided with an insulation sheet 121 extending into the interior of the insulation tube 11, wherein a limiting portion 118 may be formed on the insulation member 12 and / or the insulation tube 11. The limiting portion 118 may be used to limit the relative movement between the insulation member 12 and the insulation tube 11, thereby improving the fitting strength between the insulation member 12 and the insulation tube 11, ensuring the insulation efficiency of the insulation member 12, and thereby improving the service life and reliability of the thermal insulation assembly 10.

[0072] In some embodiments of the present application, the limiting portion 118 can abut against the inner wall of the first channel 111 to achieve positioning between the thermal insulation sheet 121 or the thermal insulation component 12 and the thermal insulation tube 11. Specifically, the limiting portion 118 abuts against the inner wall of the first channel 111 in the radial direction, wherein the radial direction refers to the radial direction of the thermal insulation tube 11. The limiting portion 118 can extend in the axial direction, and one side of the limiting portion 118 in the radial direction can abut against the inner wall of the first channel 111, thereby achieving positioning between the thermal insulation sheet 121 or the thermal insulation component 12 and the thermal insulation tube 11, thereby limiting the thermal insulation component 12 from separating from the thermal insulation tube 11.

[0073] Furthermore, if Figure 2 and Figure 3As shown, the limiting portion 118 may include a first protrusion 1211, and at least one thermal insulation sheet 121 may be provided with a first protrusion 1211 that abuts against the inner wall of the first channel 111 on at least one side facing toward or away from the thermal insulation sheet 121 adjacent thereto. It should be noted that at least one thermal insulation sheet 121 may be provided with a first protrusion 1211, and the first protrusion 1211 may be provided on one side or both sides of one thermal insulation sheet 121 facing toward or away from another thermal insulation sheet 121. The first protrusion 1211 may extend axially, and one side of the first protrusion 1211 in the radial direction may abut against the inner wall of the first channel 111, thereby limiting the thermal insulation component 12 from separating from the thermal insulation tube 11.

[0074] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, the first protrusion 1211 can abut against the inner wall of the first channel 111 on the side facing therefrom to limit the movement of the thermal insulation member 12. The first protrusion 1211 can be formed with a guide surface 1212 on the side away from the inner wall of the first channel 111. The guide surface 1212 can facilitate installation. During actual assembly, the thermal insulation member 12 and the thermal insulation tube 11 are mated by pressing. Since the first protrusion 1211 may interfere with the first protrusion 1211, the provision of the guide surface 1212 facilitates pressing the first protrusion 1211 into the first channel 111, thereby improving assembly efficiency and reducing wear on the first protrusion 1211. In a specific embodiment, the guide surface 1212 can be configured as an arcuate surface to further reduce friction during assembly and facilitate assembly of the thermal insulation member 12.

[0075] In some embodiments of the present application, the maximum dimension of the radially overlapping portion of the first protrusion 1211 and the thermal insulation tube 11 in the extension direction of the thermal insulation tube 11 is S, and its dimension satisfies the relationship: 0.2mm≤S≤1mm, that is, the radially overlapping portion of the first protrusion 1211 and the thermal insulation tube 11 can be the portion of the first protrusion 1211 that actually plays a limiting role, and the maximum dimension of this portion in the extension direction of the thermal insulation tube 11 can be the interference of the first protrusion 1211 relative to the thermal insulation tube 11. It can be understood that the radially overlapping portion of the first protrusion 1211 and the thermal insulation tube 11 in the extension direction of the thermal insulation tube 11 is The maximum dimension on the thermal insulation tube 11 is any value between 0.2 mm and 1 mm. For example, the maximum dimension of the radially overlapping part of the first protrusion 1211 and the thermal insulation tube 11 in the extension direction of the thermal insulation tube 11 can be but not limited to 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, 1 mm, etc. If the above-mentioned maximum dimension S is too large, it will increase the difficulty of installing the thermal insulation component 12. If the above-mentioned maximum dimension S is too small, it will cause the limit between the thermal insulation component 12 and the thermal insulation tube 11 to not meet the requirements. Therefore, by setting the above-mentioned maximum dimension S within the above-mentioned range, the fitting strength between the thermal insulation component 12 and the thermal insulation tube 11 can be guaranteed.

[0076] like Figure 1 and Figure 3 As shown, the thermal insulation member 12 may further include a connector 123, which may be arranged on the thermal insulation tube 11, and the connector 123 may be capable of extending axially along the thermal insulation tube 11, wherein a plurality of thermal insulation sheets 121 may be formed on the inner side surface of the connector 123 facing the first channel 111, and the plurality of thermal insulation sheets 121 may extend radially, and the plurality of thermal insulation sheets 121 may be spaced apart in the extension direction of the connector 123, optionally, the thermal insulation sheets 121 and the connector 123 may be constructed as an integral structure, or the thermal insulation sheets 121 and the connector 123 may be fixed by bonding or other connection methods.

[0077] like Figure 4 As shown, in some embodiments of the present application, the outer wall of the heat-insulating tube 11 is further formed with a mounting groove 1120, and the mounting groove 1120 can be recessed toward the first channel 111. By providing the mounting groove 1120, the occupied space of the heat-insulating tube 11 can be reduced, which is conducive to installing the heat-insulating tube 11 in the water pipe joint 21. The connecting piece 123 can cooperate with the mounting groove 1120 to realize the installation of the heat-insulating element 12 on the heat-insulating tube 11. Optionally, the connecting piece 123 and the mounting groove 1120 can be detachably connected by snapping or plugging. Further, the mounting groove 11 The bottom wall of 20 may be formed with a mounting hole 1121, and the mounting hole 1121 may be arranged to penetrate in the radial direction, and the heat insulation sheet 121 may extend into the first channel 111 through the mounting hole 1121. During actual installation, the first protrusion 1211 may also extend into the first channel 111 through the mounting hole 1121 and abut against the inner wall of the first channel 111. In some embodiments, the mounting hole 1121 may be constructed in plurality, and the plurality of mounting holes 1121 may be arranged in a one-to-one correspondence with the plurality of heat insulation sheets 121 so as to extend the plurality of heat insulation sheets 121 into the first channel 111.

[0078] like Figure 4-Figure 6 As shown, in some embodiments of the present application, the limiting portion 118 may include a second protrusion 1122, and the inner walls of the mounting groove 1120 on both sides of the circumference of the thermal insulation tube 11 may be constructed as a first side wall 1123 and a second side wall 1124. A second protrusion 1122 may be provided on at least one of the first side wall 1123 and the second side wall 1124. The second protrusion 1122 may extend toward the connector 123 and abut against the connector 123. The second protrusion 1122 may realize circumferential limitation between the connector 123 and the mounting groove 1120, thereby improving the fitting strength between the thermal insulation component 12 and the thermal insulation tube 11, and limiting the circumferential movement of the thermal insulation component 12 relative to the thermal insulation tube 11. The second protrusion 1122 may also increase the friction between the connector 123 and the side wall of the mounting groove 1120, thereby preventing the thermal insulation sheet 121 from easily falling off from the thermal insulation tube 11.

[0079] Furthermore, the second protrusion 1122 can be constructed as multiple, and the multiple second protrusions 1122 can be arranged at intervals in the axial direction. By providing multiple second protrusions 1122, the fitting strength between the thermal insulation component 12 and the thermal insulation tube 11 can be further improved to achieve the function of limiting the circumferential movement of the thermal insulation component 12 relative to the thermal insulation tube 11. In some embodiments, the second protrusions 1122 can be constructed as 4 or more to ensure the fitting strength between the thermal insulation component 12 and the thermal insulation tube 11. Among them, the maximum dimension of the second protrusion 1122 in the circumferential direction is L, satisfying the relationship: 0.2mm≤L≤1mm, that is, the maximum dimension of the second protrusion 1122 in the circumferential direction is any value between 0.2mm and 1mm. For example, the maximum dimension of the second protrusion 1122 in the circumferential direction can be but not limited to 0.2mm, 0.4mm, 0.6mm, 0.8mm, 1mm, etc. This setting can ensure that the second protrusion 1122 does not affect the assembly of the thermal insulation component 12, and can also improve the circumferential limiting effect between the connecting component 123 and the mounting groove 1120.

[0080] like Figure 7-Figure 9 As shown, in some embodiments of the present application, a first limiting portion 1125 can be formed on the bottom wall of the mounting groove 1120, and a second limiting portion 122 can be formed on the connecting member 123, and the second limiting portion 122 can be arranged corresponding to the first limiting portion 1125, and the second limiting portion 122 can also cooperate with the first limiting portion 1125, thereby limiting the movement of the connecting member 123 relative to the bottom wall of the mounting groove 1120, thereby improving the cooperation effect between the connecting member 123 and the mounting groove 1120. Further, one of the first limiting portion 1125 and the second limiting portion 122 can be constructed as a limiting hole, and the other of the first limiting portion 1125 and the second limiting portion 122 can be constructed as a limiting protrusion. In a specific embodiment, a limiting hole can be formed on the bottom wall of the mounting groove 1120, and a limiting protrusion that cooperates with the limiting hole can be formed on the connecting member 123, wherein the limiting hole can be constructed as a circular hole or a polygonal hole to facilitate processing and assembly of the limiting hole, such as Figure 13 As shown, in other embodiments, the limiting holes can also be constructed into other irregular shapes. It should be noted that the limiting holes can be applied to a variety of scenarios. For example, when the thermal insulation component 12 is processed and transported to the factory for assembly with the water pipe joint 21, the limiting holes and limiting protrusions can prevent the thermal insulation component 12 from separating from the thermal insulation tube 11 during transportation, or, in an environment with high water pressure, the limiting holes and limiting protrusions can prevent the thermal insulation component 12 from being washed away by water or deformed by impact, so that the thermal insulation component 12 and the thermal insulation tube 11 are assembled more firmly.

[0081] Furthermore, if Figure 10-12As shown, at least one of the limiting hole and the limiting protrusion can be formed with a third protrusion 1126 extending toward each other, and the third protrusion 1126 can realize the limiting cooperation between the limiting hole and the limiting protrusion. In some embodiments, the inner wall of the limiting hole can be formed with a third protrusion 1126 extending toward the limiting protrusion, and the free end of the third protrusion 1126 can abut against the outer peripheral wall of the limiting protrusion, thereby realizing the limiting cooperation between the limiting hole and the limiting protrusion. The third protrusion 1126 can be constructed in multiple ways, and multiple third protrusions 1126 can be arranged at intervals in the circumferential direction. By arranging multiple third protrusions 1126, the cooperation effect between the limiting hole and the limiting protrusion can be further improved, that is, the cooperation effect between the connecting member 123 and the mounting groove 1120 is improved.

[0082] In some embodiments of the present application, the thermal insulation sheet 121 is constructed as a rubber part. Specifically, the thermal insulation sheet 121 can be made of EPDM rubber, NBR, fluororubber, etc. The hardness of the thermal insulation sheet 121 can be designed to be between 40-70. This configuration can ensure that the thermal insulation sheet 121 can be deformed when there is water pressure, so that the first channel 111 is fully opened to ensure the circulation of water flow, and avoid the problem of partial deformation of the thermal insulation sheet 121 resulting in incomplete opening and interception of the entire water channel. The minimum deformation stress to ensure that the thermal insulation sheet 121 is fully deformed needs to be less than the water pressure in normal use scenarios, for example 0.01 MPa. When there is no water flow and pressure passing through the first channel 111, the thermal insulation sheet 121 can return to its original state, thereby reducing the heat loss inside the water tank 31. In addition, when the thermal insulation component 12 is installed, the interference position between the thermal insulation sheet 121 and the insulation tube 11 is easier to install due to the softer material design of the thermal insulation sheet 121, thereby improving assembly efficiency and reducing assembly difficulty.

[0083] The following briefly describes the connector device 20 according to the embodiment of the present application.

[0084] According to the embodiment of the present application, the connector device 20 is provided with a water pipe connector 21 and the thermal insulation component 10 of the above embodiment.

Since the connector device 20 of the embodiment of the present application is provided with the water pipe connector 21 and the thermal insulation component 10 of the above embodiment, the connector device 20 is provided with an insulation tube 11 and an insulation member 12. A limiting portion 118 can be formed on the insulation member 12 and / or the insulation tube 11. The limiting portion 118 can be used to limit the relative movement between the insulation member 12 and the insulation tube 11, thereby improving the fitting strength between the insulation member 12 and the insulation tube 11, ensuring the thermal insulation efficiency of the insulation component 10, and thereby improving the service life and reliability of the connector device 20.

A limiting portion 118 can be formed on the insulation member 12 and / or the insulation tube 11, thereby improving the fitting strength between the insulation member 12 and the insulation tube 11, ensuring the insulation efficiency of the insulation assembly 10, and thereby improving the service life and reliability of the joint device 20.

[0087] Reference below Figures 1-18 A connector device 20 for a water heater 30 according to an embodiment of the present application is described. The connector device 20 includes a water pipe connector 21, an insulating tube 11 and an insulating member 12. An axially extending mounting channel 211 is formed in the water pipe connector 21. The insulating tube 11 is arranged in the mounting channel 211 and at least a portion of the insulating tube 11 is spaced apart from the inner circumferential wall of the water pipe connector 21 to form a balancing chamber 212. The insulating tube 11 is formed with a first channel 111 extending axially therethrough. The insulating member 12 is arranged on the insulating tube 11 and at least a portion of the insulating member 12 is located in the balancing chamber 212. The insulating member 12 includes a plurality of insulating sheets 121, at least a portion of the insulating sheets 121 extends into the first channel 111, wherein a flow channel 119 is provided on the insulating tube 11 for connecting the balancing chamber 212 with the first channel 111.

[0088] like Figure 14 and Figure 15 Specifically, the connector device 20 may include a water pipe connector 21, an insulation tube 11, and an insulation member 12. A mounting channel 211 may be formed in the water pipe connector 21. The mounting channel 211 may extend axially of the water pipe connector 21. The insulation tube 11 may be disposed within the mounting channel 211. The insulation tube 11 may reduce heat within the water tank 31 during static heat preservation of the water heater 30, thereby enabling heat exchange with the external environment through the water pipe connector 21. The water pipe connector 21 may be either the water inlet or outlet connector of the water heater.

[0089] like Figure 15 As shown, at least a portion of the insulation tube 11 can be spaced apart from the inner circumferential wall of the water pipe joint 21, and a balance cavity 212 is formed between at least a portion of the insulation tube 11 and the inner circumferential wall of the water pipe joint 21. A first channel 111 can also be formed on the insulation tube 11. The first channel 111 can be set through the insulation tube 11 in the axial direction. The first channel 111 can be used for the flow of low-temperature liquid. It should be noted that the axial direction of the water pipe joint 21 is the same as the axial direction of the insulation tube 11.

[0090] The thermal insulation member 12 can be arranged on the thermal insulation tube 11. Optionally, the thermal insulation member 12 and the thermal insulation tube 11 can form a detachable connection by snapping or plugging. The thermal insulation member 12 can include a thermal insulation sheet 121. The thermal insulation sheet 121 can be constructed in multiple numbers. The multiple thermal insulation sheets 121 can be spaced apart in the axial direction or in the extension direction of the thermal insulation member 12. In some embodiments, the extension direction of the thermal insulation member 12 can be the same direction as the axial direction of the thermal insulation tube 11.

[0091] Furthermore, if Figure 15 As shown, at least part of the thermal insulation member 12 can be located in the balancing chamber 212, and a circulation channel 119 can be provided on the thermal insulation tube 11, and the circulation channel 119 can connect the balancing chamber 212 with the first channel 111. It should be explained that when water flows through the first channel 111, the pressure in the first channel 111 will output pressure to the thermal insulation member 12, making it easy for the thermal insulation member 12 to separate from the thermal insulation tube 11. To this end, by providing the circulation channel 119, it can be ensured that when water flows through the first channel 111, part of the water flow can flow into the balancing chamber 212 through the circulation channel 119, so that the balancing chamber 212 is filled with water, and then the water pressure in the balancing chamber 212 is balanced with the water pressure in the first channel 111, ensuring that the thermal insulation member 12 will not be deformed or separated from the thermal insulation member 12 due to water pressure, thereby improving the fitting strength between the thermal insulation member 12 and the thermal insulation tube 11.

[0092] In short, the connector device 20 of the embodiment of the present application includes a water pipe connector 21, an insulation tube 11, and an insulation member 12 arranged on the insulation tube 11. The insulation tube 11 can be arranged inside the water pipe connector 21 and spaced apart from the inner wall of the water pipe connector 21 to form a balance chamber 212. A first channel 111 and a circulation channel 119 can be formed in the insulation tube 11. The circulation channel 119 can connect the balance chamber 212 and the first channel 111. Therefore, after water is passed through the connector device 20, the water pressure in the balance chamber 212 and the water pressure in the first channel 111 can be kept balanced, thereby preventing the insulation member 12 from being deformed or separated from the insulation tube 11, thereby improving the connection strength between the insulation member 12 and the insulation tube 11 and the reliability of the connector device 20.

[0093] In some embodiments of the present application, the thermal insulation member 12 can be passed through the circulation channel 119, and the thermal insulation member 12 can extend into the first channel 111. It can be understood that the circulation channel 119 can provide a certain space for the installation of the thermal insulation member 12, and the circulation channel 119 after the installation of the thermal insulation member 12 can still realize the function of circulating water flow, thereby reducing the number of openings on the thermal insulation tube 11, and ensuring that the circulation channel 119 can effectively communicate with the balance chamber 212.

[0094] In some embodiments of the present application, the shortest distance between the outer wall of the thermal insulation member 12 and the inner circumferential wall of the water pipe joint 21 is D1, which satisfies the relationship: 0.05mm≤D1≤0.5mm. It can be understood that the shortest distance between the outer wall of the thermal insulation member 12 and the inner circumferential wall of the water pipe joint 21 can be any value between 0.05mm and 0.5mm. For example, the shortest distance between the outer wall of the thermal insulation member 12 and the inner circumferential wall of the water pipe joint 21 can be but not limited to 0.05mm, 0.1mm, 0.3mm, 0.5mm, etc. If the distance between the outer wall of the thermal insulation member 12 and the inner circumferential wall of the water pipe joint 21 is less than 0.05mm, the shortest distance between the outer wall of the thermal insulation member 12 and the inner circumferential wall of the water pipe joint 21 is less than 0.05mm. If the distance is too small, the thermal insulation member 12 may interfere with the inner wall of the water pipe joint 21 during installation, thereby causing deformation or damage to part of the thermal insulation member 12. If the distance between the outer wall of the thermal insulation member 12 and the inner wall of the water pipe joint 21 is too large, it will be difficult to prevent the thermal insulation member 12 from falling off. Therefore, by setting the shortest distance between the outer wall of the thermal insulation member 12 and the inner wall of the water pipe joint 21 within the above range, the thermal insulation member 12 can be further prevented from being deformed or separated from the insulation pipe 11 while ensuring that the installation of the thermal insulation member 12 does not interfere, thereby improving the reliability of the joint device 20.

[0095] like Figure 15 and Figure 16 As shown, in some embodiments of the present application, a first mating portion 13 may be formed on the outer circumferential wall of the thermal insulation tube 11, and a second mating portion 14 may be formed on the inner circumferential wall of the water pipe connector 21. The second mating portion 14 can be arranged correspondingly and mated with the first mating portion 13, thereby restricting the movement of the thermal insulation tube 11 relative to the water pipe connector 21. Optionally, the first mating portion 13 and the second mating portion 14 can be detachably connected by plugging or snapping. The provision of the first mating portion 13 and the second mating portion 14 can improve the mating strength between the thermal insulation tube 11 and the water pipe connector 21.

[0096] like Figure 17 As shown, further, the first matching portion 13 can be constructed as one of the claw 113 and the slot, and the second matching portion 14 can be constructed as the other of the claw 113 and the slot, and the outer wall of the claw 113 abuts the inner wall of the slot to achieve the snap-fitting of the claw 113 and the slot. In a specific embodiment, the first matching portion 13 can be constructed as the claw 113, and the second matching portion 14 can be constructed as the slot, and the claw 113 is snap-fitted with the slot, and the claw 113 is accommodated in the slot, and the outer surface of the claw 113 abuts the inner surface of the slot to limit the movement of the claw 113, thereby achieving the limiting between the insulation tube 11 and the water pipe joint 21.

[0097] like Figures 8-12As shown, in other embodiments of the present application, the outer peripheral wall of the insulation tube 11 can be formed with a claw 113, and the claw 113 can cooperate with the inner peripheral wall of the water pipe joint 21, thereby limiting the movement of the insulation tube 11 relative to the water pipe joint 21. It can be understood that the outer surface of the claw 113 can abut against the inner peripheral wall of the water pipe joint 21 to increase the friction between the claw 113 and the inner peripheral wall of the water pipe joint 21, that is, the friction between the insulation tube 11 and the water pipe joint 21, thereby limiting the movement of the insulation tube 11 relative to the water pipe joint 21.

[0098] like Figure 10-12 As shown, in some embodiments of the present application, a deformation hole 114 can be formed on the insulation tube 11, the claw 113 can be set on the inner wall of the deformation hole 114, and the end of the claw 113 can extend into the deformation hole 114, and the claw 113 can selectively move in the deformation hole 114. It can be understood that the claw 113 can move relative to the deformation hole 114 in the direction toward or away from the first channel 111. For example, when the insulation tube 11 is installed in the water pipe joint 21, the claw 113 can first move a certain distance toward the first channel 111, and after the claw 113 and the slot correspond, it can move in the direction away from the first channel 111 so that the claw 113 and the slot cooperate. Therefore, the above structure can facilitate the installation of the insulation tube 11, that is, avoid interference between the claw 113 and the water pipe joint 21 during installation of the insulation tube 11.

[0099] like Figure 10-12 、 Figure 16 As shown, in some embodiments of the present application, the claw 113 may include a connecting arm 1131 and a clamping head 1132, the connecting arm 1131 can be connected to the inner wall of the deformation hole 114 and extend toward the deformation hole 114, the clamping head 1132 can be set at the free end of the connecting arm 1131, and the clamping head 1132 can protrude toward the inner circumferential wall of the water pipe connector 21, wherein the outer diameter of the outer edge of the clamping head 1132 is D2, satisfying the relationship: 1.2mm≤D2≤1.5mm. It can be understood that the outer diameter of the outer edge of the clamping head 1132 can be any value between 1.2mm and 1.5mm. For example, the outer diameter of the outer edge of the clamping head 1132 can be but not limited to 1.2mm, 1.3mm, 1.4mm, 1.5mm, etc. This arrangement can ensure that after assembly, the clamping head 1132 can directly abut the inner wall of the water pipe connector 21 and generate a large force, so that the insulation pipe 11 is not easy to fall off after installation.

[0100] In some embodiments of the present application, the thermal insulation tube 11 can be constructed as a cylinder. This configuration can facilitate the installation of the thermal insulation tube 11 in the water pipe joint 21. In addition, it can also reduce the space occupied by the thermal insulation tube 11. The material of the thermal insulation tube 11 can be polyethylene (PE), polypropylene (PP), cross-linked polyethylene (PEX) and other polymer materials with relatively soft hardness. The use of the above materials can ensure that the claws 113 of the thermal insulation tube 11 are easy to deform during installation, and the installation process will not be damaged due to the brittleness of the material.

[0101] The water heater 30 according to the embodiment of the present application is briefly described below.

[0102] According to the embodiment of the present application, the water heater 30 is provided with the joint device 20 of the above-mentioned embodiment. Since the water heater 30 of the embodiment of the present application is provided with the joint device 20 of the above-mentioned embodiment, the joint device 20 of the water heater 30 includes a water pipe joint 21, an insulation tube 11 and an insulation component 12 arranged on the insulation tube 11. The insulation tube 11 can be arranged inside the water pipe joint 21 and spaced apart from the inner wall of the water pipe joint 21 to form a balancing chamber 212. A first channel 111 and a circulation channel 119 can be formed in the insulation tube 11. The circulation channel 119 can connect the balancing chamber 212 and the first channel 111. Therefore, after water is passed through the joint device 20, the water pressure in the balancing chamber 212 and the water pressure in the first channel 111 can be kept balanced, thereby preventing the insulation component 12 from being deformed or separated from the insulation tube 11, thereby improving the reliability of the water heater 30.

[0103] Reference below Figures 1-18 A connector device 20 for a water heater 30 according to an embodiment of the present application is described. The connector device 20 includes a water pipe connector 21 and an insulation tube 11. An axially extending installation channel 211 is formed in the water pipe connector 21. One end of the water pipe connector 21 is suitable for communicating with the water tank cavity 313. The insulation tube 11 is arranged in the installation channel 211 and a gap is provided between at least a portion of the insulation tube 11 and the inner circumferential wall of the water pipe connector 21, wherein at least one of the inner circumferential wall of the water pipe connector 21 and the outer circumferential wall of the insulation tube 11 is provided with a protrusion 115 extending toward each other, and the protrusion 115 is suitable for abutting against the inner circumferential wall of the water pipe connector 21 or the outer circumferential wall of the insulation tube 11 to seal the water pipe connector 21 and the insulation tube 11.

[0104] like Figure 14 and Figure 15As shown, specifically, the joint device 20 may include a water pipe joint 21 and an insulation tube 11, and an installation channel 211 is formed inside the water pipe joint 21. The installation channel 211 can extend axially of the water pipe joint 21, and one end of the water pipe joint 21 can be connected to the water tank cavity 313. The insulation tube 11 can be arranged in the installation channel 211, and at least a portion of the insulation tube 11 can be provided with a gap between the inner circumferential wall of the water pipe joint 21, wherein the insulation tube 11 can reduce the heat inside the water tank 31 when the water heater 30 is statically insulated, and perform heat exchange with the external environment through the water pipe joint 21.

[0105] Furthermore, if Figures 15-18 As shown, at least one of the inner circumferential wall of the water pipe joint 21 and the outer circumferential wall of the insulation pipe 11 can be provided with a protrusion 115, and the protrusions 115 can extend toward each other. Optionally, a protrusion 115 extending toward the inner circumferential wall of the water pipe joint 21 can be formed on the outer circumferential wall of the insulation pipe 11. The protrusion 115 can abut against the inner circumferential wall of the water pipe joint 21 and achieve sealing between the water pipe joint 21 and the insulation pipe 11. The protrusion 115 can achieve fixation between the insulation pipe 11 and the water pipe joint 21 by performing an interference fit with the insulation pipe 11. Specifically, the protrusion 115 abuts against the inner circumferential wall of the water pipe joint 21 to increase friction, thereby preventing the insulation pipe 11 from Disengage from the water pipe joint 21, or, a protrusion 115 extending toward the outer peripheral wall of the insulation pipe 11 can be formed on the inner peripheral wall of the water pipe joint 21, and the protrusion 115 can abut against the outer peripheral wall of the insulation pipe 11 to achieve fixation between the insulation pipe 11 and the water pipe joint 21, or, the inner peripheral wall of the water pipe joint 21 and the outer peripheral wall of the insulation pipe 11 are both formed with protrusions 115 extending toward each other, the protrusion 115 on the inner peripheral wall of the water pipe joint 21 can abut against the outer peripheral wall of the insulation pipe 11, and the protrusion 115 on the outer peripheral wall of the insulation pipe 11 can abut against the inner peripheral wall of the water pipe joint 21, thereby achieving relative fixation between the insulation pipe 11 and the water pipe joint 21.

[0106] In short, the connector device 20 of the embodiment of the present application is provided with a water pipe connector 21 and an insulated tube 11 installed inside the water pipe connector 21. At least one of the inner peripheral wall of the water pipe connector 21 and the outer peripheral wall of the insulated tube 11 can be provided with a protrusion 115. The protrusions 115 can extend toward each other and abut against the inner peripheral wall of the water pipe connector 21 or the outer peripheral wall of the insulated tube 11 to achieve an interference fit, thereby preventing the insulated tube 11 from detaching from the water pipe connector 21, improving the fitting strength between the insulated tube 11 and the water pipe connector 21, and ensuring the reliability of the connector device 20.

[0107] like Figure 15 and Figure 16As shown, in some embodiments of the present application, a plurality of protrusions 115 can be provided, and the plurality of protrusions 115 can be spaced apart in the axial direction of the thermal insulation tube 11. The provision of the plurality of protrusions 115 can further increase the contact area and friction between the thermal insulation tube 11 and the water pipe joint 21, thereby improving the fit strength between the thermal insulation tube 11 and the water pipe joint 21. The outer diameters of the plurality of protrusions 115 increase sequentially in the direction toward the water tank cavity 313. It is understood that the thermal insulation tube 11 is installed inward from one end of the water pipe joint 21 toward the water tank cavity 313. The configuration of the outer diameters of the plurality of protrusions 115 in this manner facilitates installation of the thermal insulation tube 11 into the water pipe joint 21.

[0108] like Figure 1 and Figure 7 As shown, in some embodiments of the present application, at least one protrusion 115 can be constructed as a ring or arc extending in the circumferential direction of the insulation tube 11. Constructing the protrusion 115 as a ring or arc can further increase the contact area and friction between the insulation tube 11 and the water pipe joint 21, thereby increasing the fitting strength between the insulation tube 11 and the water pipe joint 21.

[0109] In some embodiments of the present application, a protrusion 115 may be provided on the insulation tube 11, and the minimum outer diameter of the multiple protrusions 115 may be d1, and the inner diameter of the water pipe joint 21 may be d2, satisfying the relationship: d1>d2. It can be understood that the minimum outer diameter of the multiple protrusions 115 is larger than the inner diameter of the water pipe joint 21. Such a setting can ensure that after the insulation tube 11 is installed in the water pipe joint 21, the protrusion 115 can be interference fit with the inner wall of the water pipe joint 21, and the protrusion 115 will deform toward the insulation tube 11 to generate a radial outward force, thereby increasing the friction between the insulation tube 11 and the water pipe joint 21 and preventing the insulation tube 11 from detaching from the water pipe joint 21.

[0110] In some embodiments of the present application, the maximum outer diameter of the multiple protrusions 115 can be d3, satisfying the relationship: 1.2mm≤d3≤1.5mm. It can be understood that the maximum outer diameter of the multiple protrusions 115 is any value between 1.2mm and 1.5mm. For example, the maximum outer diameter of the multiple protrusions 115 can be but not limited to 1.2mm, 1.3mm, 1.4mm, 1.5mm, etc. If the maximum outer diameter of the protrusion 115 is too large, it will make the installation of the insulation tube 11 difficult, and the insulation tube 11 may be easily damaged during installation. If the maximum outer diameter of the protrusion 115 is too small, the fitting strength between the insulation tube 11 and the water pipe joint 21 will be insufficient, and the insulation tube 11 may easily fall out of the water pipe joint 21. Therefore, setting the maximum outer diameter of the multiple protrusions 115 within the above range can ensure that there is still an interference fit margin between the protrusion 115 of the insulation tube 11 and the water pipe joint 21, thereby ensuring that the insulation tube 11 will not fall out after installation.

[0111] like Figure 15 and Figure 16 As shown, in some embodiments of the present application, the cross-section of the protrusion 115 in the extension direction can be triangular or arc-shaped. This arrangement can ensure that after the insulation tube 11 and the water pipe joint 21 are installed, the contact area between the protrusion 115 and the inner wall of the water pipe joint 21 is small, thereby facilitating the installation of the insulation tube 11.

[0112] like Figure 7-13 As shown, in other embodiments of the present application, the outer peripheral wall of the insulation tube 11 can be formed with a claw 113, and the claw 113 can cooperate with the inner peripheral wall of the water pipe joint 21, thereby limiting the movement of the insulation tube 11 relative to the water pipe joint 21. It can be understood that the outer surface of the claw 113 can abut against the inner peripheral wall of the water pipe joint 21 to increase the friction between the claw 113 and the inner peripheral wall of the water pipe joint 21, that is, the friction between the insulation tube 11 and the water pipe joint 21, thereby limiting the movement of the insulation tube 11 relative to the water pipe joint 21.

[0113] like Figure 8 As shown, in some embodiments of the present application, the thermal insulation tube 11 may include a first section 116 and a second section 117, one end of the first section 116 can be connected to the water tank cavity 313, and a claw 113 can be formed on the first section 116, the second section 117 can be connected to the first section 116, and a plurality of protrusions 115 can be provided on the second section 117, wherein a thermal insulation member 12 can be provided at the connection between the first section 116 and the second section 117. It can be understood that the protrusions 115 and the claws 113 can be respectively provided on both sides of the thermal insulation member 12 in the axial direction, and the protrusions 115 and the claws 113 can respectively realize the limiting between the thermal insulation tube 11 and the water pipe joint 21, thereby improving the fitting strength between the thermal insulation tube 11 and the water pipe joint 21.

[0114] The water heater 30 according to the embodiment of the present application is briefly described below.

[0115] According to the embodiment of the present application, the water heater 30 is provided with the joint device 20 of the above-mentioned embodiment. Since the water heater 30 of the embodiment of the present application is provided with the joint device 20 of the above-mentioned embodiment, the joint device 20 of the water heater 30 is provided with a water pipe joint 21 and an insulation tube 11 installed inside the water pipe joint 21. At least one of the inner peripheral wall of the water pipe joint 21 and the outer peripheral wall of the insulation tube 11 can be provided with a protrusion 115. The protrusions 115 can extend toward each other and abut against the inner peripheral wall of the water pipe joint 21 or the outer peripheral wall of the insulation tube 11 to achieve an interference fit, thereby preventing the insulation tube 11 from detaching from the water pipe joint 21, thereby improving the fitting strength between the insulation tube 11 and the water pipe joint 21, and thereby improving the reliability of the water heater 30.

[0116] Reference below Figures 1-20 A water heater 30 according to an embodiment of the present application is described. The water heater 30 includes a water tank 31, a water pipe connector 21 and a water inlet pipe 34. A water tank connector 311 is provided on the water tank 31, and a water inlet channel 3111 is formed in the water tank connector 311. Part of the water pipe connector 21 is accommodated in the water inlet channel 3111 and cooperates with the water tank connector 311. Part of the water inlet pipe 34 is provided in the water inlet channel 3111, wherein a first insulating member 32 is provided between the water inlet pipe 34 and the water pipe connector 21 to separate the water inlet pipe 34 from the water pipe connector 21, and a second insulating member 33 is provided between the water inlet pipe 34 and the water tank connector 311 to separate the water inlet pipe 34 from the water tank connector 311.

[0117] like Figure 19 and Figure 20 As shown, specifically, the water heater 30 may include a water tank 31, a water pipe connector 21, and a water inlet pipe 34. The water tank 31 may be provided with a water tank connector 311. Optionally, the water tank connector 311 may be fixedly connected to the water tank 31 by welding to prevent water leakage. The water tank connector 311 may have a water inlet channel 3111 formed therein. The water inlet channel 3111 may be in communication with the inner cavity of the water tank 31. A portion of the water pipe connector 21 may be received in the water inlet channel 3111, and the water pipe connector 21 may be mated with the water tank connector 311. Optionally, the water pipe connector 21 and the water tank connector 311 may be mated by threads. Part of the water inlet pipe 34 can be arranged in the water inlet channel 3111, wherein a first insulating member 32 can be arranged between the water inlet pipe 34 and the water pipe joint 21, and a second insulating member 33 can be arranged between the water inlet pipe 34 and the water tank joint 311. The first insulating member 32 can separate the water inlet pipe 34 from the water pipe joint 21, and the second insulating member 33 can separate the water inlet pipe 34 from the water tank joint 311.

[0118] The first and second insulating members 32 and 33 are respectively provided with a water tank connector 311 and a water tank connector 311. The water tank connector 311 and the magnesium rod can be indirectly connected. The water pipe connector 21 can be connected to the water tank connector 311. Therefore, the water pipe connector 21 and the magnesium rod can also be indirectly connected. The first insulating member 32 can separate the water inlet pipe 34 from the water pipe connector 21, and the second insulating member 33 can separate the water inlet pipe 34 from the water tank connector 311. It can be understood that the first insulating member 32 and the second insulating member 33 can separate the water inlet pipe 34 from the water pipe connector 21 and the water tank connector 311 and insulate them. That is, the water inlet pipe 34 will not be connected to the magnesium rod through the water pipe connector 21 and the water tank connector 311. Even if the bottom end of the water inlet pipe 34 is connected to the magnesium rod through the water inside the water tank 31, a complete electrochemical pathway cannot be constructed, so that the magnesium rod will not protect the water inlet pipe 34, thereby avoiding excessive consumption of the magnesium rod and improving the service life of the magnesium rod.

[0119] In short, the water heater 30 of the embodiment of the present application is provided with a water tank 31, a water pipe joint 21 and a water inlet pipe 34. A water tank joint 311 is provided on the water tank 31. The water inlet pipe 34 can be arranged in the water tank joint 311, and a first insulating member 32 is provided between the water inlet pipe 34 and the water pipe joint 21, and a second insulating member 33 is provided between the water inlet pipe 34 and the water tank joint 311. The first insulating member 32 and the second insulating member 33 can respectively separate the water inlet pipe 34 from the water pipe joint 21 and the water tank joint 311, so that a complete electrochemical path cannot be formed between the magnesium rod and the water inlet pipe 34, thereby avoiding excessive consumption of the magnesium rod and improving the service life of the magnesium rod.

[0120] like Figure 20 As shown, in some embodiments of the present application, a first flange portion 341 can be formed at one end of the water inlet pipe 34 close to the water pipe joint 21. The first flange portion 341 can extend and protrude in the radial direction of the water inlet pipe 34. The first flange portion 341 can be abutted against the first insulating member 32 and the second insulating member 33 respectively, thereby realizing the first insulating member 32 and the second insulating member 33 to limit the first flange portion 341. In some embodiments, the first flange portion 341 can be constructed in a ring shape, and the first flange portion 341 can realize the function of limiting and installing the water inlet pipe 34.

[0121] like Figure 20As shown, in some embodiments of the present application, the water heater 30 may include an insulated tube 11, which may be arranged inside the water pipe joint 21, and a first insulating member 32 may be formed at one end of the insulated tube 11 close to the water pipe joint 21. The first insulating member 32 may extend radially, and one side of the first insulating member 32 may be abutted against the first flange portion 341. In some embodiments, a flange may be formed at one end of the insulated tube 11 close to the water pipe joint 21, and the flange may be constructed as the first insulating member 32, that is, the first insulating member 32 and the insulated tube 11 are constructed as an integral structure to facilitate processing and installation. The first insulating member 32 may separate the first flange portion 341 from the water pipe joint 21 and serve as an insulator.

[0122] like Figure 20 As shown, in some embodiments of the present application, the second insulating member 33 may include a first insulating portion 331 and a second insulating portion 332. The first insulating portion 331 may be arranged inside the water inlet channel 3111, and the first insulating portion 331 may be located between the water inlet pipe 34 and the inner wall of the water tank joint 311. The first insulating portion 331 may separate the water inlet pipe 34 from the inner wall of the water tank joint 311 and realize insulation between the water inlet pipe 34 and the water tank joint 311. The second insulating portion 332 can be disposed at an end of the first insulating portion 331 proximal to the insulated tube 11 and can extend radially, where the radial direction can be the radial direction of the insulated tube 11. The second insulating portion 332 can abut against the first flange portion 341. It is understood that the second insulating portion 332 can separate the first flange portion 341 from the inner wall of the water tank joint 311 and provide insulation. In some embodiments, the first insulating member 32 and the second insulating portion 332 can be located on either side of the first flange portion 341 in the axial direction of the water inlet pipe 34, thereby facilitating the first insulating member 32 and the second insulating portion 332 to axially limit the first flange portion 341.

At the same time, the second insulating portion 332 can also separate the outer periphery of the first flange portion 341 from the inner peripheral wall of the water tank joint 311 and achieve insulation. Furthermore, an extension portion 333 can be formed on the outer periphery of the second insulating portion 332, and the extension portion 333 can extend toward the first insulating member 32, and the free end of the extension portion 333 can abut against the first insulating member 32 to completely wrap the outer periphery of the first flange portion 341, thereby ensuring the insulation effect of the second insulating member 33.

When the first insulating portion 331 is installed inside the water tank 31, the third limiting portion 3311 can deform inward, thereby generating a force on the inner wall of the water tank 31, increasing the friction between the first insulating portion 331 and the water tank 31, and preventing the first insulating portion 331 from detaching from the water tank 31. Furthermore, the third limiting portion 3311 can be configured as a plurality of third limiting portions 3311, and the plurality of third limiting portions 3311 can be spaced apart in the axial direction of the water inlet pipe 34. By providing multiple third limiting portions 3311, the fit strength between the first insulating portion 331 and the water tank 31 can be further improved, preventing the first insulating portion 331 from detaching.

[0125] like Figure 20 As shown, in some embodiments of the present application, the inner wall of the water tank joint 311 can be formed with a step surface 312, and the second insulating portion 332 can abut between the step surface 312 and the first flange portion 341. The step surface 312 can provide an axial force for the second insulating portion 332, thereby achieving axial limitation of the second insulating portion 332 and the first flange portion 341. In some embodiments, the step surface 312 can be constructed as an annular surface, and the step surface 312 can also provide a certain space for the installation of the second insulating portion 332.

[0126] Furthermore, the water tank joint 311 may include a first joint section 3112 and a second joint section 3113. The first joint section 3112 may be arranged on the water tank 31, and the interior of the first joint section 3112 may be abutted against the first insulating portion 331. Specifically, the inner wall of the first joint section 3112 may be abutted against the first insulating portion 331 in the axial direction. The second joint section 3113 may be connected to one end of the first joint section 3112 close to the thermal insulation pipe 11. The second joint section 3113 may be connected to the water pipe joint 21, and a step surface 312 is formed at the connection between the second joint section 3113 and the first joint section 3112, wherein the inner diameter of the second joint section 3113 may be larger than that of the first joint section 3112 to facilitate the installation of the thermal insulation pipe 11.

[0127] like Figure 19 and Figure 20As shown, in some embodiments of the present application, the water heater 30 may further include an insulation component 314, and a water tank cavity 313 may further be formed inside the water tank 31, the water tank cavity 313 may be used to accommodate part of the water inlet pipe 34, and a magnesium rod may further be provided on the water tank 31, the magnesium rod may extend into the water tank cavity 313, and the magnesium rod may be in contact with the water in the water tank cavity 313, the insulation component 314 may be provided on the outer peripheral wall of the water tank 31, the insulation component 314 may play a role in heat insulation, and the outer wall of the insulation component 314 may be provided with a decorative component 315, and the decorative component 315 may be provided corresponding to the water pipe joint 21.
