Optionally, the elastic restoring member 300 is a restoring spring. Because of the changeability of the spring, the elasticity is large, and the vibration and the impact quantity can be absorbed, even if the telescopic part 210 retracts suddenly, the overlarge shaking can not be generated, and the stable bouncing of the heating lunch box 400 is facilitated. Of course, the invention is not limited thereto, and in other embodiments, the elastic restoring element 300 may also be an elastic sheet.

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
