An autonomous cleaning device, a method of control the autonomous cleaning device, and a storage medium are provided. The device includes a body, and a cleaning assembly, a driving assembly, wheels, a plurality of detection sensors and a controller on the body. The plurality of detection sensors are configured to transmit detection signals and receive reflection data of the detection signals reflected by an obstacle. The controller is configured to obtain reflection data reflected by the obstacle and received by the plurality of detection sensors, determine whether the obstacle has a gap according to the reflection data received by the detection sensors, and in response to the obstacle having the gap, control the autonomous cleaning device to travel, by sending control instructions to driving assembly, according to the reflection data at different time points and basic information of the autonomous cleaning device.

Autonomous cleaning device, method for travel control for autonomous cleaning device, and storage medium

An autonomous cleaning device and a noise reduction air duct device are provided for autonomous cleaning device. The autonomous cleaning device includes a body and a motor arranged on the body, and the noise reduction air duct device is mounted on the body. The noise reduction air duct device includes an upper housing, a lower housing and a support noise reduction structure made of elastic material. The lower housing and the upper housing enclose to form an air duct, an air inlet is arranged at a position of the air duct corresponding to the motor, and an air outlet is arranged on a side of the air duct away from the air inlet; the support noise reduction structure has a first end fixed on the lower housing, and a second end abutting against a lower surface of the upper housing.

Autonomous cleaning device and noise reduction air duct device thereof

Cleaning device

An automatic cleaning apparatus includes: a chassis; a front housing arranged at a front end of the chassis; and a sensing device capable sensing movement of the front housing and sending a signal to a control mainboard of the automatic cleaning apparatus when the front housing touches an obstacle and moves relative to the chassis. The sensing device includes a dust blocking member and a rocker arm that triggers the sensing device to send the signal. The rocker arm has a first end rotatably arranged inside the sensing device, and a second end passing through the dust blocking member and extending out of the sensing device. A front housing reset device is arranged on the chassis and capable of biasing the front housing toward an initial position of the front housing.

Automatic cleaning apparatus

A dust scraping device for a cleaning apparatus includes a dust cup and a removable cyclone separation unit arranged in the dust cup. The dust scraping device includes a dust scraping member. The dust scraping member has a connection portion extending in a removal direction of the cyclone separation unit, and a dust scraping portion extending to an interior of the dust cup in a direction perpendicular to the removal direction and slidably abutting against the cyclone separation unit. The dust scraping device is mounted at the dust cup, and the dust scraping portion scrapes off at least part of debris on an outer side of the cyclone separation unit when the cyclone separation unit is removed from the dust cup.

Dust scraping device and cleaning apparatus

A partition skirt device for a cleaning apparatus includes an inner ring and a skirt body. The skirt body includes: a root connected to the inner ring; an edge part arranged at an end of the skirt body away from the inner ring; and a plurality of collapsing parts arranged at intervals between the root and the edge part along a circumferential direction of the skirt body, and each extending along a radial direction of the skirt body. Along a thickness direction of the skirt body, the collapsing part protrudes relative to the skirt body on a first side surface of the skirt body and is recessed relative to the skirt body on a second side surface of the skirt body. On the first side surface of the skirt body, a size of a portion of the collapsing part protruding from the skirt body gradually decreases from the root to the edge part.

Partition skirt device and cleaning apparatus

A cyclonic separating device includes first and second cyclonic separating units. The first cyclonic separating unit is fitted over the second cyclonic separating unit. The second cyclonic separating unit includes first cyclones and second cyclones respectively arranged in a ring shape. Dust falling ends of the first cyclones define an accommodation space therebetween. The second cyclones partially extend into the accommodation space. Each first cyclone comprises first, second and third cone sections, each of which has a cone structure; airflow sucked in the first cyclones is sequentially separated by the first, second and third cone sections, and dust in the airflow is discharged from the third cone section; a central axis of the first cone section is parallel to a longitudinal axis of the dust cup; and an angle between a central axis of the second cone section and a central axis of the third cone section is 5°-20°.
