At present, a PVC plastic pipe is basically arranged between an upper metal shell and a lower metal shell, a wire penetrates through the PVC plastic pipe, and sealing cannot be directly realized between the PVC plastic pipe and the upper metal shell and the lower metal shell, so that sealing is realized by filling the inside of the PVC plastic pipe with glue. Glue filling holes are usually formed in the surface of the metal upper shell for filling glue. In addition, the upper and lower metal shells and the filling hole are sealed by filling glue. However, the thermal expansion ratios of the three materials are different, and the three materials can expand and contract repeatedly along with the repeated heating and cooling of the hot water bag, so that gaps are generated among the three materials due to inconsistent shrinkage, and the glue can age after long-term repeated heating and cooling, so that the sealing effect can not be realized any more. In addition, after glue is poured in, the temperature controller and the heating tube are wrapped, so that the sensitivity of the temperature controller can be reduced, the heating efficiency of the heating tube can be reduced, and meanwhile, substances decomposed out of the glue after being heated can corrode the temperature controller, so that the temperature controller is invalid.
