[0038] In the present application, the through hole 22 is provided on the heat insulation part 20, which is in communication with the heat insulation cavity 21, so that the liquid can be injected into the heat insulation cavity 21 through the through hole 22. In this way, the liquid in the heat insulation cavity 21 can directly contact the electric heater main body 10, and the electric heater main body 10 can directly heat the liquid in the heat insulation cavity 21, so that the liquid in the heat insulation cavity 21 is heated and evaporated to form water vapor.

[0062] Specifically, the heat insulation part 20 completely shields the outer side wall surface of the tail part heat dissipation fin 11; the outer side wall surface of the tail part heat dissipation fin 11 refers to the side wall surface of the tail part heat dissipation fin 11 away from the head part heat dissipation fin of the electric oil warmer; in this way, a better anti-scald effect can be achieved.
[0063] Optionally, the heat insulation part 20 is similar in shape to the tail part heat dissipation fin 11.
[0064] In the application, the connecting part of the heat insulation part 20 and the electric heater main body 10 is provided with the edge covering structure 25, so that the edge covering structure 25 wraps and seals the connecting part of the heat insulation part 20 and the electric heater main body 10; in this way, the sealing property of the heat insulation cavity 21 can be ensured, and the heat insulation part 20 and the electric heater main body 10 are convenient to weld.
