Cutting-off type single-droplet generating device

The invention discloses a cut-off type single droplet generating device, and relates to the technical field of fluid mechanics, in particular to a cut-off type single droplet generating device which comprises a barrel, a liquid inlet structure is arranged in the barrel, a first reset spring is arranged at the bottom of the liquid inlet structure, and a one-way conduction device is arranged on the side, away from the liquid inlet structure, of the first reset spring. A second reset spring is arranged on the side, away from the first reset spring, of the one-way conduction device, a liquid outlet structure is arranged on the side, away from the one-way conduction device, of the second reset spring, a supporting plate is fixedly installed at the bottom of the barrel, and a base is fixedly installed at the bottom of the supporting plate. According to the cut-off type single droplet generating device, the liquid passage time is controlled by adjusting the rotating speed of the movable rotating disc, liquid forms a
