Abstract

The invention provides an autonomous mower, the autonomous mower including a housing; a mowing module, a traveling module, an information collection device, an energy module, a control module and the control module includes an identification unit, and an alarm module. The autonomous mower has a security patrol working mode in which the identification unit analyzes and judges whether an abnormal object exists in the working area according to the information collected by the information collection device; if the abnormal object exists, the control module controls the alarm module to send an alarm signal to the outside. Therefore, the autonomous mower can achieve a security patrol function in addition to having a function of trimming the lawn. The autonomous mower has multiple uses, so as to save the cost.

First claim

1 - 17 . (canceled)

18 . An autonomous traveling device, which automatically travels and works in a working area, including: a housing; a working module received in said housing and performing predetermined work; a traveling module supporting said housing; an image acquisition device disposed on said housing, including a lens; an energy module providing energy for working and traveling of said autonomous traveling device; and a control module connecting and controlling said working module, said traveling module, said image acquisition device and said energy module, to achieve automatic traveling and automatic working of said autonomous traveling device; wherein said autonomous traveling device further including a cleaning device for keeping said lens clean.

19 . The autonomous traveling device according to claim 18 , said autonomous traveling device further including a cleaning control unit which controls said cleaning device to clean said lens automatically according to a preset program.

20 . The autonomous traveling device according to claim 18 , said cleaning device including a shielding sheet disposed on said lens which can be moved to shield or expose said lens, and said shielding sheet is provided thereon with a cleaning element that cleans said lens when said shielding sheet is moved.

21 . The autonomous traveling device according to claim 20 , said cleaning element is a cleaning brush or flaky cleaning plate.

22 . The autonomous traveling device according to claim 20 , said cleaning element is detachably installed on said shielding sheet.

23 . The autonomous traveling device according to claim 18 , said cleaning device including a microfan disposed on said lens which produces air currents to clean said lens.

24 . The autonomous traveling device according to claim 23 , said micro fan including fan blades made of piezoelectric material, and high-frequency vibration of said fan blades produces said air currents.

25 . The autonomous traveling device according to claim 18 , said cleaning device including a transparent cover that surrounds said image acquisition device therein and a cleaning element that cleans said transparent cover.

26 . The autonomous traveling device according to claim 25 , said cleaning element including a cleaning brush fixed to one side of said image acquisition device opposite to said lens, said transparent cover is rotatable around said image acquisition device, and when said transparent cover rotates around said image acquisition device, said cleaning brush can clean said transparent cover.

27 . The autonomous traveling device according to claim 26 , said cleaning brush is detachably installed on one side of said image acquisition device opposite to said lens.

28 . The autonomous traveling device according to claim 27 , said transparent cover is driven through a motor, and automatically rotates around said image acquisition device.

29 . The autonomous traveling device according to claim 25 , said cleaning element including a cleaning brush for cleaning said transparent cover, and said cleaning brush is located on an outer side of said transparent cover facing said lens.

30 . The autonomous traveling device according to claim 29 , said cleaning brush is driven through a motor, and can reciprocate along the outer side of said transparent cover and automatically clean said transparent cover.

31 . The autonomous traveling device according to claim 25 , said cleaning element including a spray device for cleaning said transparent cover, and said spray device is located on an outer side of said transparent cover facing the lens.

32 . The autonomous traveling device according to claim 31 , said spray device including a water jet device or an air jet device, which cleans said transparent cover through sprayed water current or air current.

33 . The autonomous traveling device according to claim 19 , said cleaning control unit compares the image collected by said image acquisition device in the preset position with a preset reference image, and when judging that they are different from each other, controls said lens cleaning device to perform a cleaning task.

34 . The autonomous traveling device according to claim 19 , said autonomous traveling device including an alarm module, and said cleaning control unit compares said image acquisition device in the preset position with a preset reference image, and when judging that they are different from each other, controls said alarm module to send an alert signal.
