Suction nozzle and hard-surface suction apparatus

The aim of the invention is to improve the manipulation of a suction nozzle, in particular for a portable hard-surface suction apparatus comprising a suction device, for cleaning hard surfaces. According to the invention, the suction nozzle has a suction opening connected to a suction channel, wherein the end of the suction channel facing away from the suction opening can be connected to the suction device. In order to achieve said aim, it is proposed that a joint is disposed or formed between the suction opening and the end of the suction channel so as to move the suction opening relative to the end of the suction channel and that a blocking device is provided for the force- and/or form-fitting blocking of the joint in at least one blocking position. The invention further relates to an improved hard-surface suction apparatus. 种吸嘴，特别是用于包括吸净装置的可携带的硬面吸净设备的吸嘴，该吸嘴具有抽吸开口，抽吸通道连到该抽吸开口上，抽吸通道的背离抽吸开口的抽吸通道端部能与吸净装置连接，为了改进在清洁硬面时对上述吸嘴的操作而提出，在抽吸开口与抽吸通道端部之间布置或构造有铰接部，其用于使抽吸开口相对抽吸通道端部运动，并且设置有闭锁装置，其用于将铰接部力锁合和/或形状锁合地闭锁在至少个闭锁位置中。
