The button cell 53 provides electric power to the integrated temperature display module 52, and the metal heat-conducting strip 51 is connected to the integrated temperature display module 52 through at least 1 metal heat-conducting wire 54. The integrated temperature display module 52 may be an integrated temperature display module that is lighted when touched, and the metal heat-conducting strip 51 and the metal heat-conducting wire 54 are used to conduct the temperature inside the thermo jug 100, and then the temperature information is displayed on the integrated temperature display module 52. In addition, the integrated temperature display module 52 and the button cell 53 should be properly treated so that they do not come into contact with water.

Optimizing:

the switch body 60 includes an outer tub 10. The outer tube 10 includes an upper tube 11, a middle tube 12, and a lower tube 13. The upper barrel 11 has an outer diameter and an inner diameter both larger than those of the middle barrel 12 so that the upper barrel 11 and the middle barrel 12 are connected by an upper transition step 14. The middle cylinder 12 has an outer diameter and an inner diameter both larger than those of the lower cylinder 13 so that the middle cylinder 12 and the lower cylinder 13 are connected by a lower transition step 15. That is, from the top down, the diameter of the outer cylinder 10 is reduced in a stepwise manner, and the upper transition step 14 and the lower transition step 15 are preferably horizontal.

A sealing sleeve 20 is arranged in the inner cavity of the upper barrel 11, the upper part of the sealing sleeve 20 is provided with a containing cavity 21 with an upward opening, and the bottom of the containing cavity 21 is provided with a transition through hole 211.
