[0035] Support member 1;

[0036] A flexible pipeline 2, the flexible pipeline 2 is coiled on the support member 1 and fixed by a positioning assembly, a circulation channel 5 is provided in the flexible pipeline 2, a heat transfer medium flows through the circulation channel 5, and a liquid injection port 3 is provided on the flexible pipeline 2, the heat transfer medium flows into the circulation channel 5 through the liquid injection port 3;

[0037] A heating element 4 is disposed in the circulation channel 5, the maximum temperature of the heating element 4 is lower than the boiling point of the heat transfer medium, both ends of the heating element 4 protrude from the support member 1 and are electrically connected to a power supply component 6; and

[0038] The protective member is wrapped around the outer peripheral side of the heating element 4, and is used to isolate the heating element 4 from the heat transfer medium, and is used to conduct the heat of the heating element 4 to the heat transfer medium.

[0039] The support member 1 is used to provide a coiling position for the flexible pipe 2 and can support the flexible pipe 2. The flexible pipe 2 injects heat transfer medium into the flow channel 5 inside the flexible pipe 2 through the injection port 3 opened thereon, and the heating element 4 is powered by the power supply component 6. After being powered on, the heating element 4 emits heat and transfers the heat to the heat transfer medium through the protective member, thereby heating the heat transfer medium, thereby heating the overall structure and achieving the heating effect of the water electric blanket. In addition, the maximum heating temperature of the heating element 4 is lower than the boiling point of the heat transfer medium, thereby ensuring that the heat transfer medium will not evaporate into water vapor during use, and also ensuring the safety and reliability of the overall use of the device.

[0040] Among them, the heat transfer medium can be any working fluid, such as water or oil, etc., and the heat transfer medium in the embodiment of the present application adopts water. The protective member is used to protect the heating element 4 located in the heat transfer medium, and it can adopt any component that can achieve a protective effect, such as silicone or rubber, etc. Of course, since the flexible pipeline 2 is coiled and arranged on the support member 1, the heating element 4 located inside the flexible pipeline 2 is preferably a flexible heating body structure, so as to avoid damage to the heating element 4 caused by the flexible pipeline 2 when coiling. The heating element 4 can also adopt any component in the prior art that can generate heat by energizing, such as a resistance wire or a heating wire. In addition, the water electric blanket provided in the present application can also absorb part of the electrical radiation of the heating wire by arranging the heating wire inside the water pipe formed by the flexible pipeline 2.

The setting of the closing pieces is used to isolate the heat transfer medium from the power supply component 6, thereby reducing the possibility of the heat transfer medium contacting the power supply component 6, and improving the safety of the overall structure.

[0045] A sealing member is also provided between the sealing member and the heating member 4, and the isolation effect of the heat transfer medium is further improved by the provision of the sealing member. Of course, optionally, a sealing member is also provided between the sealing member and the flexible pipe 2.

Thus, the flexible pipe 2 is coiled and arranged on the support 1, and the maximum coiling effect can be achieved to achieve the maximum heating effect of the water electric heating blanket.

[0050] In some embodiments, the flexible pipe 2 is coiled and arranged on the support 1, and is fixed by a positioning assembly; the flexible pipe 2 is fixed on the support 1 by the positioning assembly, so as to ensure the reliability of the flexible pipe 2 after coiling. Among them, the positioning assembly can select a suitable positioning method according to the different materials of the support 1. For example, when the support 1 is made of a hard material, the positioning assembly can be an annular lock or glue, so as to fix the flexible pipe 2 on the support 1. It can be known that when the positioning assembly adopts an annular lock, a plurality of positioning assemblies are provided, and the plurality of annular locks are arranged at intervals in the arrangement direction of the flexible pipe 2 to ensure the positioning effect. When the positioning assembly adopts glue, the part of the flexible pipe 2 used to contact the support 1 can be coated with glue, so as to bond the flexible pipe 2 to the support 1.
