Atomizing disc, atomizing device having same, and drone

摘要

An atomizing disc, an atomizing device having the same, and a drone, the atomizing disc comprising: a bottom disc (1), an upper surface of the bottom disc (1) being provided with a liquid intake space (b); a plurality of ribs (2), the plurality of ribs (2) being disposed on the upper surface of the bottom disc (1) and being spaced apart in the circumferential direction of the bottom disc (1); a centrifugal flow passage (a) that is in communication with the liquid intake space (b) is defined between two adjacent ribs (2) and the bottom disc (1); an end of a rib (2) that is close to an edge of the bottom disc (1) is provided with a first groove (5) that penetrates a side portion of the rib (2) so as to cut the fluid flowing through the centrifugal flow passage (a). The atomizing disc causes the particle size of discharged droplets to be smaller and causes spraying to be more uniform, thereby improving the spraying efficiency of the atomizing disc.
