Before using, the heating rod is put into the soft rubber channel for preheating, after the heating wire reaches the set temperature, the temperature control switch 4 is automatically turned off, and the heat conduction efficiency of the far end of the tubular body 1 is higher than that of the plastic tubular body 1 because the metal heat conduction head 2 is arranged at the far end of the tubular body 1, so that the temperature of the innermost end of the preheated soft rubber channel is higher than that of the side wall of the channel, and the tubular body 1 is filled with the heat conducting cotton 5, so that the heat of the heating wire 3 is more uniformly diffused to the peripheral wall of the soft rubber channel, and the simulation degree and the comfort during use are greatly improved.

In an implementation structure, the heat conducting head 2 comprises a ball top 21 exposed at the distal end of the tubular body 1, and a tubular assembly 22 assembled in the tubular body 1, and the heat conducting cotton 5 is also filled in the assembly 22.
