Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

If the specific posture changes, the directional indicator will also change accordingly.

[0045] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0046] In one embodiment of this application, as Figures 1 to 10 As shown, a heating module for use in an electric water heater includes a connector 1, a heating element assembly 2, and a positioning connector 3.

[0047] Specifically, the connecting seat 1 has a connecting cavity 101 and a connecting channel 102 located on the right side of the connecting cavity 101 and communicating with the connecting cavity 101; the right end of the heating tube assembly 2 is connected to the connecting cavity 101 and connected to an external power source through the connecting channel 102; the positioning connecting tube 3 is located in the connecting cavity 101 and is used to position and connect the heating tube assembly 2.

[0048] This application applies to the heating module of an electric water heater, which is connected to the heating tube group 2 via the positioning connecting pipe 3, so that the right end of the heating tube group 2 can be quickly positioned and connected in the connecting cavity 101. Subsequently, an external power supply can be connected through the connecting channel 102 to achieve electrical connection. This not only enables rapid connection and assembly, but also further improves production efficiency and reduces production costs.

[0049] Furthermore, the heating tube assembly 2 includes a heating tube body 21, a conductive electrode 22, and a sealing sleeve 23;

[0050] The heating tube 21 has a closed end on the left and an open end on the right, and an electric heating film 211 is provided on its inner wall; the conductive electrode 22 has its left end located inside the heating tube 21, and its right end extends out from the right side of the heating tube 21; the sealing sleeve 23 is located at the right end of the heating tube 21 and is penetrated by the right end of the conductive electrode 22, and is used to seal the gap between the heating tube 21, the conductive electrode 22 and the connecting cavity 101.

[0051] This application utilizes the electrothermal film 211 on the inner wall of the heating tube 21 to quickly respond to changes in current and achieve rapid heating. Furthermore, since the electrothermal film 211 is directly attached to the inner wall of the heating tube 21, it has high heat transfer efficiency, reduces heat loss, and achieves efficient electrothermal conversion, thereby improving the overall heating efficiency.

[0052] In addition, the sealing sleeve 23 ensures a seal between the opening at the right end of the heating tube 21 and the conductive electrode 22, preventing the entry of air and moisture. This not only extends the service life of the heating tube assembly 2, but also ensures that the heating film 211 can work in a dry environment, avoiding short circuits or performance degradation caused by moisture.

[0053] Furthermore, a sealing colloid 2000 is provided between the heating tube 21 and the connecting cavity 101, located on the left side of the sealing sleeve 23, for sealing the gap between the heating tube 21 and the connecting cavity 101. Its advantage is that it forms a secondary seal, ensuring an absolutely sealed connection.

[0054] Furthermore, the conductive electrode 22 includes a left contact ring 221, a right contact ring 222, a connecting insulating plate 223, a left contact ring wire 224, and a right contact ring wire 225;

[0055] The left contact ring 221 is located inside the left side of the heating tube body 21, with a left break 2211 along its circumferential direction, and its outer surface is in contact with the heating film 211. The right contact ring 222 is located inside the right side of the heating tube body 21, with a right break 2221 along its circumferential direction, and its outer surface is in contact with the heating film 211. The connecting insulating plate 223 is located between the sealing sleeve 23 and the positioning connecting tube 3. The left end of the left contact ring wire 224 is connected to the left contact ring 221, and its right end is connected to the connecting insulating plate 223 and extends to the right inside the positioning connecting tube 3. The left end of the right contact ring wire 225 is connected to the right contact ring 222, and its right end is connected to the connecting insulating plate 223 and extends to the right inside the positioning connecting tube 3. The purpose is to form a closed circuit with the heating tube body 21 covered with the heating film 211, meeting the requirements for heating upon power-on.

[0056] Furthermore, the outer surface of the left touch ring 221 is provided with a silver plating layer, or a gold plating layer, preferably a silver plating layer; the outer surface of the right touch ring 222 is provided with a silver plating layer, or a gold plating layer, preferably a silver plating layer. The advantage is that metallic silver has excellent conductivity, and its cost is relatively cheaper than that of gold plating.

[0057] Furthermore, the electrothermal film 211 is a nano-electrothermal film. The material used to make the nano-electrothermal film is nano-silver. Its advantages are that nano-silver not only has outstanding conductivity, but also has outstanding characteristics such as rapid heating, energy saving, high stability, and long service life.

[0058] Furthermore, the sealing sleeve 23 has a covering and connecting cavity 231 on the left side for covering and connecting the right end of the heating tube 21, and a positioning connecting ring groove 2311 is provided on the right side inside the covering and connecting cavity 231 for positioning and connecting with the right end of the heating tube 21; the purpose of this is to adapt and connect the heating tube 21.

[0059] The sealing sleeve 23 also has a left contact wire clearance through hole 232 communicating with the covering and connecting cavity 231 to allow the left contact wire 224 to extend to the right, and a right contact wire clearance through hole 233 communicating with the covering and connecting cavity 231 to allow the right contact wire 225 to extend to the right. The purpose is to adapt for connecting the conductive electrode 22.

[0060] Furthermore, the connecting channel 102 is inclined on the left and lower on the right. The purpose of this is to position the connecting cavity 101 connected to it at a lower position, so that the heating tube assembly 2 connected to the connecting cavity 101 can be in a lower position, thereby ensuring that the heating tube assembly 2 can always be submerged in water, and thus effectively preventing dry burning.

[0061] Furthermore, the heating module used in the electric water heater also includes a temperature detector 4 mounted on the connector 1 for detecting temperature, the temperature detector 4 being located on the upper side of the heating element assembly 2. Its advantage is that it can not only detect problems with the water being heated by the heating element assembly 2 in real time, but also further prevent dry burning.

[0062] Furthermore, the heating element 21 is made of quartz glass, borosilicate glass, or ceramic, preferably quartz glass. Quartz glass has the advantages of high temperature resistance, high dielectric strength, and a low coefficient of thermal expansion, making it very suitable for the application requirements of the heating element 21.
