A scraping element and a window scraper, the widow scraper comprising: a window scraper main unit (1) and a scraping element (2); the window scraper main unit (1) is provided with a liquid collection box (3) and a suction machine unit (4); the scraping element (2) comprises a scraping element housing (21), which contains a suction channel (211) and is provided with an upper scraping strip (22) and a lower scraping strip (23). A suction opening (212) is formed between a first surface (223) of the upper scraping strip (22) and a first surface (236) of the lower scraping strip (23), and is in communication with the suction channel (211). A second surface (235) on the reverse side of the first surface of the lower scraping strip (23) is provided with several channels (231) and/or through holes (237) arranged at intervals along the lengthwise direction of the lower scraping strip (23). The channels (231) pass through a front end surface (232) of the lower scraping strip (23) and the through holes (237) pass through the first surface (236) of the lower scraping strip (23). The suction machine unit (4) is in communication with the suction channel (211) so as to create a suction force at the suction opening (212) when the suction machine unit (4) is in operation, and the liquid collection box (3) is provided with a cavity. By providing the channels (231) and/or through holes (237) in the lower scraping strip (23), when cleaning a glass surface, the liquid collected below the lower scraping strip (23) passes through the channels (231) and/or the through holes (237) and is suctioned by the suction opening (212), thereby improving the suction effect. |
