Title:
CENTRIFUGAL SWING DISC, SPRAYING DEVICE AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/119244
Kind Code:
A1
Abstract:
Disclosed are a centrifugal swing disc (100), a spraying device and an unmanned aerial vehicle. The centrifugal swing disc (100) is used for rotating and spraying a liquid pesticide, and comprises an upper swing disc (1) and a lower swing disc (2), which are arranged concentrically, wherein a channel for spaying the liquid pesticide is formed between the upper swing disc (1) and the lower swing disc (2), and a flow guide groove (11) is arranged on a side, facing the lower swing disc (2), of the upper swing disc (1). When the centrifugal swing disc (100) centrifugally sprays the liquid pesticide, the flow guide groove (11) serves as a block on an outer side of the top of a place where the liquid pesticide tends to gather, and can thus prevent the liquid pesticide splashing out from a gap between the flow guide groove (11) and a lower surface of the upper swing disc (1) from having an impact on the flow guide efficiency of the flow guide groove (11), thereby improving the atomization effect.
