Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0026] Please refer to Figure 1 and Figure 2A cleaning robot provided by an embodiment of the present invention includes: a robot body 201; a walking device 202, which is arranged on the robot body 201 and is used to drive the robot body 201 to walk along a working surface; a cleaning device 203, including a suction cup 204, an air suction hole 205 and a nozzle 206, the suction cup 204 is arranged on the robot body 201, a cavity 207 is formed in the suction cup 204, the air suction hole 205 and the nozzle 206 are arranged in the cavity 207, the nozzle 206 is used to spray cleaning liquid onto an object to be cleaned, and the air suction hole 205 is used to suck air to inhale the cleaning liquid so that the suction cup 204 can be adsorbed on the object to be cleaned.

[0027] The cleaning robot in this embodiment can drive the robot body 201 to walk along the working surface through the walking device 202, and perform cleaning operations on the objects to be cleaned through the cleaning device 203. During the cleaning process, air suction through the suction hole 205 can form a negative pressure in the cavity 207 so that the suction cup 204 is adsorbed on the object to be cleaned, and the cleaning liquid is sprayed to the object to be cleaned through the nozzle 206, thereby cleaning the object to be cleaned. The used cleaning liquid will be sucked by the suction hole 205, thereby completing the thorough cleaning of the object to be cleaned. Since the suction cup 204 is adsorbed on the object to be cleaned, the cleaning liquid will not flow out of the suction cup 204, which is conducive to the complete recovery of the cleaning liquid, thereby improving the use effect of the cleaning robot.

[0028] In this embodiment, preferably, the cleaning device 203 further includes a bracket 208 and a rotating shaft 209, the bracket 208 and the rotating shaft 209 are located in the cavity 207, the bracket 208 is rotatably connected to the suction cup 204 through the rotating shaft 209, the rotating shaft 209 is used to drive the bracket 208 to rotate, and there are multiple nozzles 206, and the multiple nozzles 206 are arranged on the bracket 208. Therefore, the bracket 208 is driven to rotate by the rotating shaft 209, which is conducive to improving the spraying force, spraying range and uniformity of the cleaning liquid, thereby further improving the cleaning effect.

[0029] In this embodiment, preferably, the rotating shaft 209 is arranged along the axial direction of the suction cup 204, the bracket 208 extends along the radial direction of the suction cup 204, and the plurality of nozzles 206 are evenly distributed on the bracket 208. Thus, it is beneficial for the cleaning liquid to evenly cover the range defined by the cavity 207 during the spraying process, thereby further improving the cleaning effect.

[0030] In this embodiment, preferably, the bracket 208 is cross-shaped, and the rotating shaft 209 is connected to the intersection of the cross, so that the bracket 208 has a simple structure, saves materials, and can make the cleaning liquid evenly cover the range defined by the cavity 207 during the spraying process.

[0031] In this embodiment, preferably, there are a plurality of air suction holes 205, and the plurality of air suction holes 205 are evenly distributed along the circumference of the suction cup 204. This can improve the adsorption force of the suction cup 204 and improve the recovery effect of the cleaning liquid.

[0032] In this embodiment, preferably, the suction cup 204 is a rubber suction cup 204. Therefore, when the suction cup 204 is adsorbed with the object to be cleaned, it can be deformed according to the shape of the surface of the object to be cleaned, thereby improving the fit with the object to be cleaned, improving the adsorption effect, and more effectively preventing the cleaning liquid from flowing out of the suction cup 204.

[0033] Please refer to Figure 3 In this embodiment, preferably, the cleaning robot further includes a recovery pipe 210, a first end of the recovery pipe 210 is connected to the suction cup 204 and communicated with the suction hole 205, a second end of the recovery pipe 210 is used to be connected to the containing device, the suction hole 205 is used to suck the cleaning liquid into the recovery pipe 210, and the recovery pipe 210 is used to transport the cleaning liquid to the containing device. Thus, through the suction effect of the suction hole 205, the used cleaning liquid can be sucked into the recovery pipe 210 and transported to the containing device located outside the cleaning robot through the recovery pipe 210, so that there is no need to store the used cleaning liquid in the cleaning robot, which is conducive to reducing the weight of the cleaning robot.

[0034] Please refer to Figure 4 and Figure 5 In this embodiment, preferably, the cleaning robot also includes an adsorption device 100, the adsorption device 100 includes an adsorption member 101, a connecting plate 102 and an elastic member 103, the adsorption member 101 is used to be adsorbed on the working surface, and the two ends of the elastic member 103 are respectively connected to the adsorption member 101 and the connecting plate 102, and the elastic member 103 is supported between the connecting plate 102 and the adsorption member 101 so that the connecting plate 102 and the adsorption member 101 can maintain a relative positioning state; the walking device 202 is a crawler device, and a connecting portion is provided on the crawler device, and the connecting portion is connected to the connecting plate 102, and the elastic member 103 extends along the radial direction of the crawler device so that the adsorption member 101 is located outside the crawler device.

[0035] Through the expansion or contraction of the elastic member 103, the adsorption member 101 and the connecting plate 102 can move relative to each other. When the crawler device walks on a non-planar working surface, the adsorption member 101 will be subjected to the pressure of the working surface. Under the action of the pressure and the elastic force of the elastic member 103, the adsorption member 101 will move relative to the connecting plate 102, so that the adsorption member 101 can fit the working surface, thereby helping to improve the adsorption force of the adsorption member 101 on the working surface, preventing the crawler device from detaching from the working surface and falling off, and improving the reliability of use. At the same time, under the support of the elastic member 103, the stability of the crawler device can be guaranteed.

[0036] In this embodiment, preferably, there are multiple adsorption devices 100, and the multiple adsorption devices 100 are arranged at intervals along the circumference of the crawler device. The crawler device is adsorbed and supported on the working surface by the multiple adsorption devices 100, which can improve the adsorption strength of the crawler device on the working surface, thereby improving the reliability and stability of the crawler device walking on the working surface.

[0037] In this embodiment, preferably, the crawler device also includes a guide device 104, the guide device 104 includes a connecting rod 105 and a first pin 106, the first end of the connecting rod 105 is hinged to the adsorption member 101 through the first pin 106, and the first pin 106 is perpendicular to the setting direction of the elastic member 103; a through hole 107 is provided on the connecting plate 102, and the connecting plate 102 is sleeved between the first end and the second end of the connecting rod 105 through the through hole 107, and the connecting rod 105 can be extended and retracted in the through hole 107. When the crawler device moves on a non-planar working surface, the adsorption member 101 will be subjected to the pressure of the working surface. Under the action of the pressure and the elastic force of the elastic member 103, the adsorption member 101 will drive the connecting rod 105 to expand and contract in the perforation 107, and the adsorption member 101 will rotate relative to the connecting plate 102 with the first pin 106 as the center, so that the adsorption member 101 can fit with the working surface, thereby facilitating the adsorption force of the adsorption member 101 on the working surface, preventing the crawler device from detaching from the working surface and falling, and improving the reliability of use. In addition, the guide device 104 limits the direction of relative movement of the adsorption member 101 and the connecting plate 102, thereby improving the supporting force of the adsorption device 100.

[0038] In this embodiment, preferably, the connecting plate 102 is arranged along the width direction of the crawler device, the first pin shaft 106 is perpendicular to the width direction of the crawler device, and there are multiple guide devices 104, and the multiple guide devices 104 are arranged at intervals along the width direction of the crawler device. Since the first pin shaft 106 is perpendicular to the width direction of the crawler device, the guide device 104 limits the relative movement of the adsorption member 101 and the connecting plate 102 in the direction perpendicular to the radial and width directions of the crawler device, further improving the supporting force of the adsorption device 100. Multiple guide devices 104 are arranged at intervals along the width direction of the crawler device, which can effectively prevent the adsorption member 101 from rotating relative to the connecting plate 102 with the connecting rod 105 as the center, thereby improving the stability and reliability of the use of the adsorption device 100.

[0039] In this embodiment, preferably, the adsorption device 100 also includes a limiter 108, which is connected between the second end of the connecting rod 105 and the connecting plate 102 to limit the connection plate 102 from moving toward the second end of the connecting rod 105; the elastic member 103 is a spring, and each connecting rod 105 is sleeved with a spring, which is used to apply elastic pressure to the adsorption member 101 and the connecting plate 102 so that the adsorption member 101 and the connecting plate 102 can maintain a relative positioning state. Thus, the spacing between the connecting plate 102 and the adsorption member 101 can be limited by the limiter 108, so that the spring can maintain a compressed state, and then the spring can apply elastic pressure to the adsorption member 101 and the connecting plate 102 so that the adsorption member 101 and the connecting plate 102 can maintain a relative positioning state, thereby improving the supporting force of the adsorption device 100. Since the spring is sleeved on the connecting rod 105, the connecting rod 105 can provide support force to the spring, prevent the spring from being damaged due to excessive deformation, and improve the reliability of the use of the adsorption device 100. In addition, since the multiple guide devices 104 are arranged at intervals along the width direction of the track device, the springs mounted on the connecting rod 105 are naturally also arranged at intervals along the width direction of the track device. Therefore, the supporting force for the adsorption component 101 and the connecting plate 102 can be improved, so that the connecting plate 102 and the adsorption component 101 can better maintain a relative positioning state, thereby improving the reliability of the use of the adsorption device 100.

[0040] In this embodiment, preferably, the limiting member 108 is a limiting nut, and the connecting rod 105 is provided with a threaded section, and the limiting nut is threadedly matched with the threaded section. During the assembly process of the adsorption device 100, the connecting rod 105 can be first hinged to the adsorption member 101 through the first pin 106, and then the spring is sleeved on the connecting rod 105, and then the connecting plate 102 is sleeved on the connecting rod 105 through the perforation 107, and then the limiting nut is sleeved on the threaded section, and the limiting nut is rotated to move along the threaded section to press the connecting plate 102, so that the spring is kept in a compressed state, thereby making it easy to assemble and adjust the adsorption device 100. Of course, the limiting member 108 is also a limiting protrusion set on the connecting rod 105.

[0041] In this embodiment, preferably, the adsorption device 100 also includes a guide wheel 109, the adsorption member 101 extends along the width direction of the crawler device, and the guide wheel 109 is connected to the end of the adsorption member 101 through a second pin shaft 110, and the second pin shaft 110 is parallel to the first pin shaft 106. When the crawler device walks on a non-planar working surface, the adsorption member 101 will be subjected to the pressure of the working surface. Under the action of the pressure and the elastic force of the elastic member 103, the adsorption member 101 will rotate relative to the connecting plate 102 with the first pin shaft 106 as the center. During the rotation of the adsorption member 101 relative to the connecting plate 102, the guide wheel 109 will contact the working surface and slide on the working surface. At this time, the guide wheel 109 can rotate relative to the adsorption member 101 with the second pin shaft 110 as the center, thereby effectively avoiding the end of the adsorption member 101 directly colliding with the working surface to cause damage, and making the crawler device move more smoothly on the working surface.

[0042] In this embodiment, preferably, the bottom surface of the adsorption member 101 is used to contact the working surface, and the bottom end of the guide wheel 109 is located below the bottom surface of the adsorption member 101, thereby reducing the friction between the adsorption member 101 and the working surface.

[0043] In this embodiment, preferably, the adsorption member 101 includes a frame 111 and a magnetic block 112, both of which extend along the width direction of the crawler device, the guide wheel 109 is connected to the two ends of the frame 111 through the second pin 110, the magnetic block 112 is connected to the frame 111 and is located between the two ends of the frame 111, and the magnetic block 112 is used to be adsorbed on the working surface. As a result, the adsorption member 101 has a simple structure, reliable adsorption, and is easy to assemble. Of course, the magnetic block 112 can also be replaced by the vacuum adsorption device 100.
