Document Type and Number:
Japanese Patent JP2023078535
Kind Code:
A
Abstract:
To provide a liquid type specification device and a liquid container with improved merchantability.SOLUTION: A liquid type specification device includes: a propagation body 10 arranged at a position opposite to a bottom 3a of a container 3 and having a propagation surface 11 on which a surface wave Ws propagates; a piezoelectric element 30 that generates the surface wave Ws by imparting vibration to the propagation body 10 to detect a reflected surface wave Ws; and a control unit 2 for specifying a type of a liquid 4 based on a propagation time of the surface wave Ws detected by the piezoelectric element 30. The propagation surface 11 is a non-flat surface toward a liquid level 4a side of the liquid 4 as it is separated from the piezoelectric element 30.SELECTED DRAWING: Figure 2
