Abstract

The utility model discloses a temperature measuring device and a cooking utensil, the temperature measuring device comprises a housing and a temperature sensing element extending into the housing, the housing is provided with a top wall and a side wall, at least three insulating layers are arranged between the temperature sensing element and the top wall, an insulating shell is also arranged in the housing, at least part of the insulating shell is arranged between the temperature sensing element and the side wall, and the insulating layer is arranged between the top wall and the side wall. The insulating layers are arranged on the inner side and the outer side of the insulating shell so as to increase the creepage distance between the temperature sensing element and the side wall. The insulating shell is arranged between the temperature-sensing element and the shell, so that the creepage path of current at the temperature-sensing element can reach the side wall only by crossing the insulating shell along the surface of the insulating shell, and the creepage distance between the temperature-sensing element and the shell is further increased. According to the utility model, the heat of the housing is transmitted to the temperature sensing element through heat radiation, the temperature sensing sensitivity and the temperature measurement accuracy of the temperature sensing element are improved, the internal space of the housing can be effectively saved, and the manufacturing cost is reduced.
