The meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0035] Please refer to Figures 1 to 3The embodiment of the present application provides a window cleaning robot 100, which is used for cleaning a cleaning area, and the cleaning area can be a wall body, and the wall body can be an outer surface of a building. The wall body can be a glass curtain wall, and the glass curtain wall is usually composed of large glass panels, structural frames made of aluminum or steel materials and sealing materials. The glass curtain wall has a suspended edge, and the intersection of two glass curtain walls can also form a corner edge. The window cleaning robot 100 can also be used for cleaning the outer surface of other objects, which is not limited here and can be selected according to actual conditions.

[0036] Please refer to Figures 1 to 3 The window cleaning robot 100 comprises a main machine shell 10, a probe foot 20 and a cleaning cloth. The main machine shell 10 is arranged relative to the cleaning area. Usually, the cleaning area is arranged in a vertical direction, and the main machine shell 10 is arranged in the vertical direction relative to the cleaning area, and the main machine shell 10 can move along the cleaning area with the aid of a running mechanism 40.

[0037] Please refer to Figures 1 to 3 The cleaning cloth is connected to the surface of the main machine shell 10 facing the cleaning area. The cleaning cloth is made of a flexible material and can clean the cleaning area. The flexible material can be cotton.

[0038] Please refer to Figures 1 to 3 The probe foot 20 is slidably connected to the edge of the main machine shell 10 in a predetermined direction and is connected and fixed to the cleaning cloth. The probe foot 20 has a retracted state in the cleaning area and an extended state outside the cleaning area. It can be understood that when the probe foot 20 is in the retracted state, the probe foot 20 abuts against the cleaning cloth towards the cleaning area, so that the cleaning cloth can move with the main machine shell 10 and clean the cleaning area. When the main machine shell 10 moves to the edge of the cleaning area, the probe foot 20 leaves the cleaning area. Here, the probe foot 20 is switched from the retracted state to the extended state under the action of an external force, and at this time, the running mechanism 40 is triggered to change the running direction, so as to avoid the crash of the window cleaning robot 100. The predetermined direction is the direction perpendicular to the plane of the cleaning area. In the embodiment, the predetermined direction is the horizontal direction, and in other embodiments, the predetermined direction can be selected according to actual conditions, which is not limited here.

[0039] Please refer to Figures 1 to 3The probe foot 20 further has a guide surface 22 arranged on the side surface thereof and inwardly, the guide surface 22 is convexly curved and used for guiding the probe foot 20 to return to the cleaning area. The guide surface 22 is arranged inwardly, that is, the guide surface 22 is directed to the center position of the main machine shell 10, and when the probe foot 20 is in the extended state, the guide surface 22 abuts against the edge of the cleaning area, and after the running structure changes the running direction, the guide surface abuts against the edge of the cleaning area. Since the guide surface is arranged in a convexly curved manner, the probe foot 20 can be guided to slide in the horizontal direction, so that the probe foot 20 is switched from the extended state to the retracted state until the probe foot 20 is completely returned to the cleaning area.

[0040] Please refer to Figures 1 to 3 The window-cleaning robot 100 provided by the embodiment of the present application has the guide surface 22 arranged on the inner side surface of the probe foot 20, the guide surface 22 is convexly curved, and when the probe foot 20 leaves the cleaning area and is in the extended state, the guide surface 22 can guide the probe foot 20 to return to the cleaning area smoothly. The probe foot 20 is connected to the cleaning cloth, so that the area of the cleaning cloth covering the probe foot 20 is increased, the dead angle of the window-cleaning robot 100 during the working process is avoided, and the convenience of using the window-cleaning robot 100 is improved. In some embodiments, the guide surface 22 is spherical and surrounds the probe foot 20 along the circumferential part of the probe foot 20.

[0041] Please refer to Figures 1 to 3 Optionally, the guide surface 22 is spherical, the center of the sphere determined by the guide surface 22 is located in the probe foot 20, and the guide surface 22 at least partially surrounds the probe foot 20 along the circumferential part of the probe foot 20, so that the probe foot 20 can be guided and returned to the cleaning area by the guide surface 22 at any angle, and the instability factors caused by friction and inappropriate angles are also reduced. The guide surface 22 arranged in a spherical manner effectively avoids the collision or jamming of the probe foot 20 with the edge of the cleaning area, and improves the convenience and flexibility of using the window-cleaning robot 100.

[0042] Please refer to Figures 1 to 3 In some embodiments, the probe foot 20 further has a mounting surface 21, the mounting surface 21 is located on the end surface of the probe foot 20 facing the cleaning area and is connected to the cleaning cloth.

[0043] Please refer to Figures 1 to 3Optionally, in the embodiment, the mounting surface 21 is arranged in a vertical direction and in a planar shape, and the cleaning cloth part is connected to and covers the mounting surface 21 completely, so that the connecting area of the cleaning cloth and the probe foot 20 can be improved, and the stability of the cleaning cloth can be improved. Of course, in the embodiment, the cleaning cloth is in a rectangular shape, and the cleaning cloth is connected to the mounting surface 21 at the right-angle position, so that the edge of the cleaning cloth is not easy to curl in the working process, and the cleaning effect of the cleaning cloth is improved. The connection between the planar mounting surface 21 and the cleaning cloth makes the connection between the cleaning cloth and the probe foot 20 more stable, reduces the possibility of loosening or falling off of the cleaning cloth in the operation process, and improves the cleaning efficiency and the overall performance of the window cleaning robot 100.

[0044] Please refer to Figures 1 to 3 In some embodiments, the window cleaning robot 100 further comprises a connecting layer 50 arranged on the mounting surface 21, the connecting layer 50 connects and fixes the cleaning cloth, and the shape of the connecting layer 50 is adapted to the shape of the mounting surface 21.

[0045] Optionally, by arranging the connecting layer 50 on the mounting surface 21, the fixing and stability between the cleaning cloth and the probe foot 20 are strengthened. The adaptability of the shape of the connecting layer 50 to the mounting surface 21 makes the connection between the cleaning cloth and the mounting surface 21 more close, so that the cleaning cloth can be fixed with the maximum area, and the edge of the cleaning cloth is not easy to curl in the working process, and the cleaning effect of the cleaning cloth is improved.

[0046] Please refer to Figures 1 to 3 In the embodiment, the connecting layer 50 is a magic tape, one side surface of the magic tape can be glued to the mounting surface 21 and basically covers the mounting surface 21 completely, and the hook surface of the other side of the magic tape is detachably connected to the cleaning cloth. The flexible magic tape covers the entire mounting surface 21, avoiding scratching the glass in the cleaning area by the probe foot 20. Of course, the connecting layer 50 can also be a gluing layer, which is not limited here and can be selected according to the actual situation.

[0047] Please refer to Figures 1 to 3 In some embodiments, the probe foot 20 further has an outwardly expanded surface 23 located on the side surface thereof, the outwardly expanded surface 23 is arranged outwardly, the guide surface 22 and the outwardly expanded surface 23 are located on opposite sides of the probe foot 20 respectively, and the outwardly expanded surface 23 extends and intersects the mounting surface 21.
