Abstract: The invention provides an apparatus (1) for cleaning a surface, the apparatus (1) comprising: a body (10) defining a cavity (10a), the body (10) terminating in a distal end (12) that is adapted, in use, to be in the vicinity of a surface to be cleaned (2) such that the surface to be cleaned (2) forms an end wall of a chamber (11) including the cavity (10a); at least one cleaning liquid inlet (14) for flow of a cleaning liquid into the chamber (11); a divider (16) located in or at the end of the cavity (10a) that divides the chamber (11) into a first portion (11a) and a second portion (11b), the second portion (11b), in use, being in fluid communication with the surface (2) to be cleaned; and an acoustic transducer associated with the first portion of the chamber (11) to introduce acoustic energy into the chamber (11); wherein the divider is adapted to permit the passage of acoustic energy therethrough from the first portion (11a) of the chamber (11) to the second portion (lib) of the chamber (11) to thereby allow pressure fluctuations to be generated at the surface (2) to be cleaned. The invention also provides a method of cleaning a surface (2).

Abstract translation: 本发明提供了一种用于清洁表面的装置（1），所述装置（1）包括：限定空腔（10a）的主体（10），所述主体（10）终止于远端（12） 使用于待清洁表面（2）附近，使得待清洁表面（2）形成包括腔（10a）的腔室（11）的端壁; 至少一个清洁液体入口（14），用于将清洁液体流入所述腔室（11）中; 位于所述腔室（10a）的端部或所述腔室（10a）的端部的分隔件（16），所述腔室（11）将所述腔室（11）分成第一部分（11a）和第二部分（11b），所述第二部分（11b） 与待清洁的表面（2）流体连通; 以及与所述腔室（11）的第一部分相关联的声学换能器以将声能引入所述腔室（11）中; 其中所述分隔件适于允许声能从所述腔室（11）的所述第一部分（11a）通过所述腔室（11）的第二部分（11b），从而允许在所述表面处产生压力波动 （2）待清洗。 本发明还提供了一种清洁表面（2）的方法。
