  • Patent number: 11896174
    Abstract: An autonomous cleaning device, including: a casing, a cover, and a switch. The cover is arranged on the casing and protrudes from a top of the casing. The cover and the casing are connected in a manner enabling the cover to be movable downwards and backwards; and the cover has an acting portion. A trigger position of the switch is located at a moving path of the acting portion, and the cover is configured to trigger the switch by the acting portion during movement of the cover. The switch comprises at least two first switches, configured to be triggered in a horizontal direction. A horizontal circumferential trigger range formed by all the at least two first switches is greater than or equal to 180 degrees.
