Japanese Patent JP7359304

B2

The present disclosure indicates a bubble generating device (1) that is attached to a liquid tank and generates, by vibration, fine bubbles in a liquid in the liquid tank. The bubble generating device (1) includes a vibration plate (2), a first cylindrical body (31), a spring (32), a second cylindrical body (33), and a piezoelectric element (4). The vibration plate (2) has a plurality of pores, is in contact with a liquid on one surface, and is in contact with a gas on another surface. The first cylindrical body (31) holds, at one end, the vibration plate (2). The spring (32) having a plate shape supports another end of the first cylindrical body (31). The second cylindrical body (33) supports, at one end, a position of the spring (32) outside a position where the first cylindrical body (31) is supported. The piezoelectric element (4) is provided at another end of the second cylindrical body (33) and vibrates the second cylindrical body (33).
