Description

The present invention relates to a liquid container including a detection unit that detects a liquid amount and a liquid temperature in an inner container.

In general, in order to know the amount of liquid in the inner container whose liquid level cannot be seen directly from the outside, for example, an inner container with a vacuum double bottle structure having an upper end opening and a lower end narrow mouth is provided, and a pumping pipe is set up in front of the inner container. The lower end of the pumping pipe is connected to the lower end of the inner container, the pumping pipe is provided so as to be visible from the front of the liquid container, and the amount of liquid in the inner container can be confirmed through the liquid level of the pumping pipe. There is a liquid container of construction.

However, in such a conventional liquid container, since the liquid level in the inner container can only be confirmed by the presence of the pumping pipe standing in front of the inner container in communication with the inner container, As a liquid container having a structure having only a top opening such as a vacuum double bottle and no pumping pipe communicating with the inner container, there is a problem that the liquid level in the inner container, that is, the amount of liquid cannot be known at all. .

Moreover, there is a problem that it is impossible to know at all whether the liquid temperature in the inner container, particularly in the vacuum double bottle, is maintained at a desired temperature as well as the liquid surface, that is, the liquid amount.

Therefore, the present applicant attaches a detection unit having a liquid amount detection means and a liquid temperature detection means in the inner container, and provides a space portion in the shoulder member of the liquid container, and a power source and a main control board are provided in the space portion.
