[0028] Please refer toFigures 1 to 3 The embodiment of the present application provides a window cleaning robot 100 which is used for cleaning a wall of a building, and the wall can be a glass curtain wall which is composed of large glass panels, aluminum or steel structural frames and sealing materials. The window cleaning robot 100 can also be applied in other different environments and situations, and is not limited to cleaning the wall in the present application, but also can be used for cleaning the outer surface of other objects such as windows, and the specific use object can be selected according to actual needs, which is not limited herein.

[0029] Please refer to Figures 1 to 3 The window cleaning robot 100 comprises a main machine 101, a sensing mechanism 30 connected to the main machine 101 and a cleaning cloth 10 made of flexible material. It can be understood that the main machine 101 can be adsorbed on the surface to be cleaned such as the glass curtain wall through a vacuum pump or a fan, and the sensing mechanism 30 is used for sensing the position of the main machine 101 such as the edge of the glass curtain wall. The material of the cleaning cloth 10 can be cotton, so that the cleaning cloth 10 can clean the sundries and dirt on the glass curtain wall in the moving process of the main machine 101.

[0030] Please refer to Figures 1 to 3 The sensing mechanism 30 comprises a sensor in the main machine 101, a detection piece 31 slidably connected to the main machine 101 and an elastic piece 32 connected to the detection piece 31. The cleaning cloth 10 is connected to the main machine 101 and covers the detection piece 31; it can be understood that the glass curtain wall is vertically arranged, and the main machine 101 is adsorbed on the glass curtain wall, so that the sliding direction of the detection piece 31 is along the direction perpendicular to the glass curtain wall, the elastic piece 32 has elastic restoring force, which can be compressed and deformed under the adsorption force of the main machine 101, and the two ends of the elastic piece 32 are connected to the detection piece 31 and the main machine 101 respectively, so that the elastic piece 32 can apply the elastic force to the detection piece 31, and the detection piece 31 has the tendency to move outward from the main machine 101.

[0031] Please refer to Figures 1 to 3, the detection piece 31 has a retracted state and an extended state, when the detection piece 31 is in the retracted state, the elastic piece 32 is compressed and deformed and drives the detection piece 31 to press the cleaning cloth 10; that is, when the host 101 is located on the glass curtain wall and away from the edge of the glass curtain wall, the host 101 is adsorbed on the glass curtain wall, and the cleaning cloth 10 contacts the glass curtain wall, the elastic piece 32 is compressed, the detection piece 31 presses the cleaning cloth 10 towards the glass curtain wall under the action of the elastic force applied by the elastic piece 32, so that the cleaning cloth 10 is in close contact with the glass curtain wall, and the detection piece 31 does not contact the glass curtain wall, so that the detection piece 31 can avoid scratching the glass curtain wall. When the host 101 moves the cleaning cloth 10, the cleaning effect of the cleaning cloth 10 on the glass curtain wall can be improved. Since the position of the detection piece 31 is also covered by the cleaning cloth 10, there is no cleaning dead angle during cleaning, and the cleaning effect is improved.

[0032] It can be understood that when the detection piece 31 is in the extended state, the detection piece 31 triggers the inductor, that is, when the host 101 moves to the edge of the glass curtain wall, the cleaning cloth 10 partially separates from the glass curtain wall, and at this moment the detection piece 31 is in a suspended state. Since the cleaning cloth 10 is made of flexible material, the elastic piece 32 cannot drive the detection piece 31 to extend outward, and the detection piece 31 triggers the inductor during the extension, and the host 101 changes the moving direction and retreats according to the information of the inductor, thereby avoiding the risk of crashing.

[0033] Please refer to Figures 1 to 3 The window cleaning robot 100 provided by the embodiment of the application can improve the cleaning effect and reliability of the cleaning cloth 10, reduce the risk of scratching the glass curtain wall, trigger the inductor when the host 101 moves to the edge of the glass curtain wall without a frame, prevent the window cleaning robot 100 from crashing, and improve the safety of the window cleaning robot 100.

[0034] It can be understood that the window cleaning robot 100 provided by the application can clean the glass curtain wall with a frame and the glass curtain wall without a frame.

[0035] Please refer to Figures 1 to 3 In some embodiments, the detection piece 31 includes a detection rod 311 slidably connected to the host 101 at one end and a detection head 312 located at the other end of the detection rod 311, and the detection head 312 presses the cleaning cloth 10 when the detection piece 31 is in the retracted state.

[0036] Optionally, the outer diameter of the detection rod 311 is smaller than the outer diameter of the detection head 312, so that the detection head 312 has a larger contact area with the cleaning cloth 10, ensuring that the cleaning cloth 10 is uniformly pressed when pressed, avoiding excessive compression or loosening, improving the effect of pressing the cleaning cloth 10, and further improving the cleaning effect of the cleaning cloth 10.

[0037] It can be understood that when the detection piece 31 is in the extended state, the elastic piece 32 drives the detection head 312 to move outward, and at the same time, the detection rod 311 slides relative to the main machine 101. The detection rod 311 triggers the inductor during sliding.

[0038] Referring to Figure 2 and Figure 5 In some embodiments, the window cleaning robot 100 further comprises a connecting piece 40, and the two sides of the connecting piece 40 are connected to the cleaning cloth 10 and the detection head 312, respectively.

[0039] Optionally, the connecting piece 40 ensures that the cleaning cloth 10 and the detection head 312 are closely combined, and the cleaning cloth 10 is not easy to fall off during use, ensuring the continuity and stability of the cleaning process, and also ensuring that the cleaning cloth 10 does not have the phenomenon of edge rolling and edge folding during long-term use, thereby improving the cleaning effect.

[0040] Referring to Figure 2 and Figure 5 It can be understood that the connecting piece 40 can be a magic tape, the magic tape is glued to the detection head 312, and the hook surface of the magic tape is bonded to the cotton cleaning cloth 10.

[0041] It can also be understood that the connecting piece 40 can also be a glue piece, and the two side surfaces of the glue piece are glued to the cleaning cloth 10 and the detection head 312, respectively.

[0042] Referring to Figure 2 and Figure 5 It can also be understood that the connecting piece 40 can be a magnetic piece, the magnetic piece is glued to the cleaning cloth 10, and the material of the detection head 312 can be metal iron, so as to connect the cleaning cloth 10 and the detection head 312 through the magnetic attraction effect.

[0043] Referring to Figure 2 and Figure 5 In some embodiments, the detection head 312 is provided with a containing cavity 313, the containing cavity 313 is in an open cavity structure, and the connecting piece 40 is partially located in the containing cavity 313.

[0044] Optionally, the accommodating cavity 313 of the detection head 312 can effectively accommodate the connecting piece 40, so that the connecting piece 40 is partially located in the accommodating cavity 313, and the connecting piece 40 exposes the cleaning cloth 10 from the accommodating cavity 313, thereby effectively reducing the overall thickness of the window cleaning robot 100.

[0045] It can also be understood that the accommodating cavity 313 can also protect the connecting piece 40 from external physical damage and ensure stable connection and prevent loosening after repeated use.

[0046] Please refer to Figure 4 and Figure 5 In some embodiments, the cross-sectional area of the detection head 312 is tapered along a predetermined direction, which is the axial direction of the detection rod 311 and points to the cleaning cloth 10.

[0047] Optionally, the detection head 312 is a circular truncated cone, and the side surface of the circular truncated cone is an inclined slope 314, so that when the detection member 31 is in the extended state, the detection head 312 is suspended outside the glass curtain wall, and when the main machine 101 changes the moving direction, the side surface of the circular truncated cone can abut against the edge of the glass curtain wall and guide the detection head 312 to return to the glass curtain wall, thereby improving the convenience of use of the window cleaning robot 100.

[0048] It can be understood that when cleaning a glass curtain wall without a frame and the edge of the glass curtain wall is not a straight edge, the cooperation between the circular truncated cone and the edge of the glass curtain wall can make the detection head 312 return to the surface of the glass curtain wall without hanging outside the frame of the glass curtain wall, thereby preventing the detection head 312 from not returning to the glass curtain wall.

[0049] Please refer to Figure 4 and Figure 5 In some embodiments, the elastic member 32 is a tube spring that is sleeved on the detection rod 311, one end of the tube spring abuts against the main machine 101, and the other end of the tube spring abuts against the detection head 312.

[0050] Optionally, the tube spring can provide a stable restoring force for the detection member 31, so that the detection member 31 can tightly abut against the cleaning cloth 10 when in the retracted state, and when the main machine 101 moves to the edge of the glass curtain wall, the tube spring can drive the detection member 31 to be in the extended state, thereby preventing failure of state switching and improving the reliability of use of the window cleaning robot 100.

[0051] Optionally, the tube spring can effectively reduce the wear of the elastic member 32 and prolong the service life of the window cleaning robot 100.

[0054] Referring to Figure 2 and Figure 5 Optionally, the thickness of the cleaning cloth 10 ranges from 0.3 mm to 2.5 mm, so that not only can the appropriate thickness of the cleaning cloth 10 be flexibly selected according to different cleaning requirements and working environments, but also the adaptability of the window cleaning robot 100 to different surfaces and different degrees of dirt can be improved. Moreover, since the thickness of the cleaning cloth 10 is thin enough, the cleaning cloth 10 will not be relatively high above the main machine 101, so that the center of gravity of the window cleaning robot 100 is closer to the glass curtain wall. When the window cleaning robot 100 cleans the glass surface of the low frame, the window cleaning robot 100 will not have the risk of rushing out of the glass surface.
