    Abstract: A steam brush head and a cleaning apparatus. The steam brush head comprises: a brush seat assembly, which is provided with a chamber communicated with the outside, and a first channel and a second channel which are communicated with the outside, a plurality of notches (14) being formed on an outer edge of an opening end of the brush seat assembly; and a brush head assembly, provided in the chamber of the brush seat assembly and communicated with the second channel. The first channel is used for forming a dust removal channel (3); the second channel is used for forming a cleaning channel (4) for conveying steam or cleaning water; the opening end of the brush seat assembly can be pressed to cover a surface to be cleaned, such that the chamber and said surface cooperate to define a cleaning chamber (15); the notches (14) and said surface cooperate to define air vents communicated with the cleaning chamber; the second channel and the first channel are both communicated with the cleaning chamber (15); steam or cleaning water sprayed out from the second channel enters the cleaning chamber (15) to clean said surface; and waste steam or wastewater after cleaning is completed flows into the first channel through the cleaning chamber (15).

    Abstract: A radar decorative cover assembly (100), comprising: mounting bases (2) and nozzle assemblies (10). Each of the mounting bases (2) is provided with a first mounting hole (21) extending in a preset direction. Each of the nozzle assemblies (10) comprises a telescopic nozzle (1) and a nozzle decorative lid (6); the nozzle decorative lid (6) is connected to a free end of the telescopic nozzle 1; the nozzle decorative lid (6) is used to match a through hole (41) of a radar decorative cover (4); and the telescopic nozzle (1) is movably provided between a retracting position and an extending position in the preset direction, wherein at least part of the peripheral surface of the telescopic nozzle (1) located at the retracting position is located in the first mounting hole (21), and at least part of the peripheral surface of the telescopic nozzle (1) located at the retracting position matches at least part of the peripheral wall surface of the first mounting hole (21). Also disclosed are a lidar device (300) having the radar decorative cover assembly and a vehicle. The radar decorative cover assembly can reduce a reserved gap between the nozzle decoration lid and the through hole of the radar decoration cover, thereby effectively reduce the entry of dust into the radar decorative cover.
