Document Type and Number:
WIPO Patent Application WO/2023/035746
Kind Code:
A1
Abstract:
An anti-collision mechanism, a cleaning head, and a cleaning appliance. The anti-collision mechanism comprises a protective cover (3) that is rotatably connected to a cleaning head main body (1), wherein a baffle (4) is arranged between the protective cover (3) and a roller (2), and a horizontal collision absorption component and a vertical collision absorption component are arranged between the protective cover (3) and the baffle (4). When in use, an end portion of the cleaning head moves forward. When the cleaning head is located at a corner, such as in contact with the corner of wall, the protective cover (3) deforms to a certain extent in a horizontal direction, and an action force of a collision is absorbed by the horizontal collision absorption component, thereby reducing the force transmitted to the baffle (4); and when the cleaning head is in a space with a small height, the top of the cleaning head is in contact with an object, and energy is absorbed by the vertical collision absorption component.
