Title:
DIAPHRAGM PUMP AND PLANT PROTECTION UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2020/098061
Kind Code:
A1
Abstract:
A plant protection unmanned aerial vehicle (1000), comprising a diaphragm pump (100). The diaphragm pump (100) comprises a pump body assembly (10), a motor assembly (20) and a liquid discharge assembly (30). The pump body assembly (10) is provided with a liquid outlet (11), the motor assembly (20) is connected to the pump body assembly (10) and is used to drive the pump body assembly (10) to pump a liquid from the liquid outlet (11), and the motor assembly (20) comprises a motor base (22). The liquid discharge assembly (30) is in communication with the liquid outlet (11) and is used to discharge the liquid, and the liquid discharge assembly (30) is in contact with the motor base (22), and uses the liquid to conduct heat generated by the motor assembly (20). The liquid discharge assembly (30) of the diaphragm pump (100) is in contact with the motor base (22), so that when the liquid from the liquid outlet (11) flows through the liquid discharge assembly (30), the heat generated by the motor assembly (20) can be conducted, thereby effectively dissipating the heat of the motor assembly (20). The diaphragm pump (100) does not need to be additionally provided with a heat dissipation structure, and the weight of the diaphragm pump (100) is not increased, facilitating the installation of the diaphragm pump (100).
