Description

Technical Field

[0001] The utility model relates to the technical field of heat preservation devices, in particular to a heat preservation device for drinking water in a vehicle. Background Art

[0002] Some long-distance buses and trucks use thermos bottles for drinking water or ice water. These bottles are easy to tip over, break, or spill, making them inconvenient and unsafe to use. It is not convenient to place thermos bottles in small vehicles such as sedans.

[0003] For example, a vehicle-mounted water cup insulation device in the prior art (publication number: CN106864338B) can heat drinking water while driving; the pressure sensor transmits a signal to the controller, and the controller starts the heating of the heating wire, that is, the controller starts the heating of the heating wire only when the heating wire is pushed out. After the heating wire retracts into the protective cover tube, the pressure sensor cannot collect a signal, and the controller turns off the heating of the heating wire to prevent the heating wire from burning dry.

[0004] In the process of heating a water cup or a baby bottle, if the radius of the water cup or the baby bottle is small, it is easy for the water cup or the baby bottle to be loosely fixed and shake. At the same time, when the heating wire is working all the time, it wastes electricity and is easy to cause a fire. Utility Model Content
