Patent ID: 10271699

Abstract:
The present disclosure relates to an autonomous cleaning device and a wind path structure for use in the autonomous cleaning device. The wind path structure includes: a cleaning component for cleaning cleaned objects, a cleaned object storage container for storing the cleaned objects, and a power component for generating a wind, the cleaning component, the cleaned object storage container, and the power component being arranged sequentially in a moving direction of the autonomous cleaning device; a first-level wind duct located between the cleaning component and the cleaned object storage container, wherein the first-level wind duct is coupled with the power component such that the cleaned objects are delivered to the cleaned object storage container by the wind generated by the power component; and a second-level wind duct located between the cleaned object storage container and the power component, wherein the second-level wind duct has a bell-mouth shape and includes an inner wall, the inner wall including an arc-shaped segment facing toward the wind coming from the cleaned object storage container to direct the wind to an air inlet of the power component.
