Title:
CLEANING TOOL
Document Type and Number:
WIPO Patent Application WO/2020/211337
Kind Code:
A1
Abstract:
A cleaning tool, comprising a tool body (20), a fan assembly (22) provided on the tool body (20) and a dust collecting device (24) that communicates gas with the fan assembly (22); the cleaning tool also comprises a rolling brush assembly provided in the tool body (20), the rolling brush assembly comprising a rolling brush (26); the cleaning tool also comprises a lower cover (44) provided on the tool body (20), a scraping strip (46) fixedly provided on the lower cover (44) and a swing arm (48) movably provided on the lower cover (44); the scraping strip (46) and the rolling brush (26) define a channel that communicates gas with the dust collecting device (24). A surface on which the cleaning tool travels is a working surface; once the swing arm (48) contacts the working surface and is pressed against so as to float, the swing arm (48) abuts against the scraping strip (46) to thereby drive the scraping strip (46) to float. The described cleaning tool has low traveling resistance on any working surface, and has a better sealing and dust guiding effect, which greatly improves the dust suction performance.
