Dreame Innovation Technology (Suzhou) Co., Ltd.

The present application provides an air guiding structure and an air handling device, which relates to the technical field of air handling devices. The air guiding structure is mounted at an air outlet of an air handling device and includes: an adjusting assembly, including a carrier and air guiding vanes movably connected to the carrier, where the carrier extends along a length direction of the air outlet, and the air guiding vanes are sequentially provided along a plate surface of the carrier; and a driving assembly, which drives the carrier to change its position relative to the air outlet, and which drives each air guiding vane to change its position relative to the carrier.

The present disclosure provides a cleaning robot and a movement control method thereof. Based on the method, during travel of the cleaning robot, three-dimensional information of an obstacle is acquired through a sensor system. When the obstacle moves within the detection range of the sensor system, when a distance between the obstacle and the cleaning robot along a central axis of the cleaning robot is less than a first preset detection threshold, and when a maximum value among included angles between connection lines constituted by a first reference point of the cleaning robot and second reference points of the obstacle and a current traveling direction of the cleaning robot is greater than a third preset detection threshold, an action away from the obstacle is intelligently performed.

The present disclosure provides a control method for cleaning robot, the method comprises: in case where a wet cleaning assembly performs a cleaning task on the operating surface at least in a mopping state, the cleaning robot is being hijacked and the time of being hijacked is greater than a preset time, the wet cleaning assembly changes from the mopping state to a mop folding state, wherein the being hijacked means that the cleaning robot leaves the operating surface; the cleaning robot quits being hijacked and continues to perform the cleaning task, in case where the operating surface is a floor or ceramic tile, the cleaning assembly switches from the mop folding state to the mopping state; in case where the operating surface is a carpet, the cleaning assembly remains in the mop folding state, the mopping state means that the mop is in the state of being released.

A method and apparatus for identifying a ground feature by an automatic cleaning device. The method includes collecting a rolling-brush current and a side-brush current; performing weighted calculation according to the rolling-brush current and the side-brush current, so as to obtain a ground identification coefficient; and according to the ground identification coefficient, identifying a feature of whether the ground on which the automatic cleaning device is located is carpet or a non-carpet dielectric surface. Software optimization is carried out on the basis of current detection technology, thus reducing the false identification rate without additional cost.

Provided is a cleaning robot, including a robot body and a side brush assembly. The side brush assembly includes a driving mechanism, a swing arm, and a cleaning member. The swing arm is rotatably connected to the robot body about a first rotation axis, and the cleaning member is disposed on the swing arm and is adapted to perform a cleaning operation; the driving mechanism is adapted to drive the swing arm to rotate about the first rotation axis, so that the swing arm moves between an extended position and a retracted position relative to the robot body; the cleaning member is farther away from the robot body when the swing arm is in the extended position than when it is in the retracted position; and when the swing arm is in the extended position, the cleaning member can clean a corner between an edgewise path and a preset obstacle.

The present disclosure provides a control method for cleaning robot, the method comprises: in case where a wet cleaning assembly performs a cleaning task on the operating surface at least in a mopping state, the cleaning robot is being hijacked and the time of being hijacked is greater than a preset time, the wet cleaning assembly changes from the mopping state to a mop folding state, wherein the being hijacked means that the cleaning robot leaves the operating surface; the cleaning robot quits being hijacked and continues to perform the cleaning task, in case where the operating surface is a floor or ceramic tile, the cleaning assembly switches from the mop folding state to the mopping state; in case where the operating surface is a carpet, the cleaning assembly remains in the mop folding state, the mopping state means that the mop is in the state of being released.
