阅读说明：本技术 一种无人机 (Unmanned aerial vehicle ) 是由 刘利剑 于 2018-10-30 设计创作，主要内容包括：一种无人机,包括：机身(10)、旋翼(11)、气罩(12)、冲洗气道(13)以及抽吸气道(14)；其中,机身(10)包括相对的第一侧和第二侧,旋翼(11)设置于机身(10)的第一侧；气罩(12)设置于机身(10)的第二侧,与旋翼(11)的位置相对,用于将旋翼(11)产生的旋翼气流设置在气罩(12)内；冲洗气道(13)设置于气罩(12)内,与旋翼(11)相对设置,用于将部分旋翼气流转变成高速的冲洗气流,将待清洁装置上的杂物冲洗至气罩(12)内；抽吸气道(14)设置于气罩(12)内,与旋翼(11)相对设置,用于将气罩(12)内的杂物抽吸到抽吸气道(14)内。该无人机可以用于清洁待清洁装置,不仅清洁效率较高,还可以避免对待清洁装置表面的损伤。(An unmanned aerial vehicle, comprising: the aircraft comprises a fuselage (10), a rotor wing (11), an air hood (12), a flushing air passage (13) and a suction air passage (14); the aircraft comprises a fuselage (10), a rotor wing (11), a first connecting piece and a second connecting piece, wherein the fuselage (10) comprises a first side and a second side which are opposite to each other, and the rotor wing (11) is arranged on the first side of the fuselage (10); the air hood (12) is arranged on the second side of the fuselage (10) and is opposite to the position of the rotor wing (11) and used for arranging the rotor wing airflow generated by the rotor wing (11) in the air hood (12); the flushing air passage (13) is arranged in the air hood (12) and is opposite to the rotor wing (11) and used for converting partial rotor wing airflow into high-speed flushing airflow and flushing sundries on the device to be cleaned into the air hood (12); the air suction channel (14) is arranged in the air hood (12) and is opposite to the rotor wing (11) and used for sucking sundries in the air hood (12) into the air suction channel (14). This unmanned aerial vehicle can be used for the cleanness to treat cleaning device, and not only clean efficiency is higher, can also avoid treating the damage on cleaning device surface.)
