Title:
DUST COLLECTION BOX USED FOR CLEANING APPARATUS, AND CLEANING APPARATUS HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2023/035565
Kind Code:
A1
Abstract:
A dust collection box (100) used for a cleaning apparatus (200), and the cleaning apparatus (200) having same. The dust collection box (100) comprises a box body (1) and a flow guide plate (2), wherein the box body (1) is internally provided with a dust collection chamber (10), and is also provided with an air inlet (11) and a dust outlet (12) which are separately in communication with the dust collection chamber (10); the flow guide plate (2) is arranged in the dust collection chamber (10), and is suitable for guiding an airflow entering from the air inlet (11) to two sides or corners of the dust collection chamber (10); the lower end of the flow guide plate (2) is spaced apart from the bottom wall of the dust collection chamber (10); the flow guide plate (2) is at least partially constructed as a flexible member; and when the airflow pressure at the air inlet (11) is greater than a preset value, the flexible member deforms, such that a gap between the lower end of the flow guide plate (2) and the bottom wall of the dust collection chamber (10) becomes wider. By means of at least partially constructing the flow guide plate (2) as a flexible member, the airflow guide effect of the flow guide plate (2) is cleverly combined with the circulation property of the airflow, thereby improving the functionality of the flow guide plate (2); and the flow guide plate (2) can not only improve the airflow guide effect, thereby improving the capability of cleaning side edges and corners of the dust collection chamber (10), but can also ensure the circulation property of the airflow, thereby preventing the blockage of an air duct.
