[0028] In one preferred embodiment described above, the support 1 forms a chamber 102 by opening a recess along the axial direction, the connecting cavity 304 of the protective frame 3 is installed to cooperate with the chamber 102, and an extension rod 306 is integrally molded to the side wall of the protective frame 3 on the side of the connecting cavity 304, the end of which extends into the chamber 102, and at least a portion of the thermostat 7 reaches the chamber 102.

[0029] The above technical solution, by installing the chamber 102, better protects the thermostat 7 and prevents the bag from being deformed by external pressure, which would affect the normal operation of the thermostat 7.

[0030] In one preferred embodiment described above, the support 1 is made of die-cast aluminum and may be a integrally molded structure, and a heat dissipation section is provided on the outside of the support 1. To improve heat dissipation, a heat dissipation structure such as heat dissipation fins 103 is provided on the outside of the support 1, and heat dissipation ribs 104 are provided on the heat dissipation fins 103. A gap 105 is provided between the heat dissipation fins 103 and the outer wall of the chamber 102, and the support 1 comprises the chamber 102 and a support member 106. The first mounting portion 101 is opened on the support member 106 in a U-shape, and the heat dissipation fins 103 connect the support 1 and the outer wall of the chamber 102.

[0031] In other embodiments, the support 1 may be formed of a thermally conductive material such as copper or iron.

[0032] The first mounting portion 101 is provided with a first mounting groove for assembling the heating tube 2. Here, both side walls of the first mounting groove may abut the heating tube 2 facing inward so that the heating tube 2 can be stably mounted within the first mounting groove.

[0033] The second mounting portion 301 is provided with a second mounting groove for attaching the support 1.

[0034] In one preferred embodiment described above, the protective frame 3 is provided with a position limiting portion for limiting the position of the support frame and the heating tube 2.

[0036] In one preferred embodiment described above, the protective frame 3 comprises a first frame 307 and a second frame 308 that are buckle-connected.

[0037] In one preferred embodiment described above, the coupler body 4 comprises a plug-in structure 401 and a flexible connector 402 located at least partially outside the plug-in structure 401. The flexible connector 402 is provided with a connecting groove 601, and the protective frame 3 is provided with a connecting projection 602 that cooperates with the connecting groove 601 to limit the position of their engagement. This flexible portion may be made of PVC material. A face cover 403 is rotatably connected to the outside of the plug-in structure 401.

[0038] Here, at least a portion of the outer wall of the protective frame 3 located in the connecting cavity 304 has an engaging mounting portion 310 formed therein for engaging with the outer wall of the chamber 102, and a plurality of perforations 309 are provided on the outside of the protective frame 3.

[0039] This utility model has a simple structure, and preferably, the aluminum die-cast support 1 and the heating tube 2 can be assembled and installed, thus simplifying the installation process. Furthermore, since the coupler body 4 is integrated with the heating tube 2 via the protective frame 3, the heating structure inside the bag is integrated, making manufacturing and installation easier.

[0040] In other words, in this utility model, the heating element 2 is assembled onto an aluminum die-cast support 1, then the thermostat 7 is assembled inside the chamber 102, and then the protective frame 3 and coupler body 4 are attached. The coupler body 4 is integrated with the heating element 2 via a third connecting part and heated.

[0041] Here, the plug-in structure 401 includes a joint 801 having three chambers 807, and two electrodes 802, which function as positive and negative electrodes respectively, are located in two of the three chambers 807 (i.e., the first and second positions in the three chambers 807). A baffle 805 is located in the third position in the three chambers 807 and separates the two electrodes 802 that function as positive and negative electrodes. Thus, the two electrodes 802 that function as positive and negative electrodes respectively, and the installation electrode 804 are each located inside one of the chambers 807.

[0042] In the above technical solution, since the recess 803 is located in the joint 801 of the existing hot water bottle, small conductive impurities such as screws can easily enter the recess 803, potentially causing a short circuit when the power cord is connected, as the positive and negative terminals connect. In this utility model, by adding a baffle 805, firstly, it prevents elongated impurities from falling in, and secondly, even if impurities do fall in, the baffle 805 separates the positive and negative terminals, effectively preventing a short circuit.

[0043] The plug-in structure 401 further comprises a ground electrode 804, and the baffle 805 separates the positive electrode, negative electrode, and ground electrode 804 into pairs.

[0044] The positive electrode, negative electrode, and ground electrode 804 are arranged in a triangular shape, and the baffle 805 is Y-shaped and attached to the recess 803 to separate the positive electrode, negative electrode, and ground electrode 804.

[0045] Here, the baffle 805 comprises a baffle sheet 806, the first ends of the three baffle sheets 806 are connected, and the second ends have adaptive grooves 808 that fit into the inner wall of the recess 803.

[0046] The baffle 805 may be integrally molded with the inner wall of the recess 803, or the baffle 805 may be manufactured separately and mounted inside the recess 803.

[0047] This heating structure further comprises a plug 9 that fits into the joint 801, the plug 9 being provided with a projection 901 that fits into a recess 803.
