Title
(EN) DIAPHRAGM PUMP AND AGRICULTURAL UNMANNED AERIAL VEHICLE
(FR) POMPE À MEMBRANE ET VÉHICULE AGRICOLE AÉRIEN SANS PILOTE
(ZH) 隔膜泵及农业无人机
Abstract
(EN)
Provided are a diaphragm pump (100) and an agricultural unmanned aerial vehicle (1000). The diaphragm pump (100) comprises a pump body mechanism (10), a one-way valve mechanism (20), a diaphragm mechanism (30) and an eccentric mechanism (50), wherein the one-way valve mechanism (20), the diaphragm mechanism (30) and the eccentric mechanism (50) are mounted on the pump body mechanism (10); the diaphragm mechanism (30) comprises a pump cover (31) and a diaphragm (32) connected to the pump cover; the one-way valve mechanism (20) comprises a one-way valve (21) and a valve cover (22), and the one-way valve (21) is mounted on the pump body mechanism (10) via the valve cover (22); the pump cover (31) is mounted on the pump body mechanism (10) and covers the diaphragm (32) and the valve cover (22), and the diaphragm (32) is detachably connected to the eccentric mechanism (50); the pump cover (31) and the diaphragm (32) jointly form a diaphragm cavity (310), and a flow channel (313) in communication with the diaphragm cavity (310) is formed at an inner side face of the pump cover (31); and a liquid flows into or out of the diaphragm cavity (310) through the flow channel (313).
