Scraping head of surface cleaning device and surface cleaning device

The invention discloses a scraping head of a surface cleaning device and the surface cleaning device. The scraping head of the surface cleaning device comprises a scraping head shell, an upper scraping strip and a lower scraping strip. The scraping head shell is provided with a first air channel connected with a vacuum source. One end of the upper scraping strip and one end of the lower scraping strip are both fixed to the scraping head shell to serve as the fixed ends. The other ends, capable of moving relative to the fixed ends, of the upper scraping strip and the lower scraping strip serveas the free ends. The first surface of the upper scraping strip and the first surface of the lower scraping strip get close to each other to form a suction port communicating with the first air channel. At least the free end of the lower scraping strip is provided with wavy wrinkles. Thus, the scraping head has the advantages of being easier to manufacture and lower in manufacturing cost. 本发明公开了一种表面清洁器的刮头及其表面清洁器，其中，该表面清洁器
