The floor cleaning device includes a mopping device, which includes a mopping unit, and the mopping unit includes a mopping component for mopping the floor. The mopping unit and / or the walking device are oscillatingly connected to the chassis of the cleaning robot so that the mopping component of the mopping unit can maintain contact with the ground by oscillating according to the unevenness of the ground.

[0003] The aforementioned robot is unable to scrape off and collect dirt adhering to the ground during the ground cleaning process, resulting in the inability to remove highly adhesive dirt from the ground. Furthermore, the robot needs to return to the base station to clean its cleaning components during the cleaning process, thereby reducing cleaning efficiency. Summary of the Invention

[0004] The present invention provides a cleaning robot and system thereof to solve the technical problems described in the background section above.

[0005] The purpose and effectiveness of the cleaning robot and its system of the present invention are achieved by the following specific technical means: A cleaning robot and its system includes a body, a chassis, and a motion component.

[0008] Furthermore, a partition is fixedly connected to the center of one side of the water storage cavity, and the partition divides the water storage cavity into a sewage cavity and a clean water cavity. At the same time, the clean water cavity and the sewage cavity are respectively connected to the water pipe. A cleaning liquid cavity is opened on the other side of the water storage cavity, and the cleaning liquid cavity is aligned with the clean water cavity. At the same time, a through hole is opened on the inner wall between the cleaning cavity and the clean water cavity.

[0009] Furthermore, the bottom of the wiper blade is in contact with the ground and the bottom of the wiper blade is smooth. An air outlet is provided on the outer wall in front of the wiper blade. The top of the wiper blade is connected to the built-in air channel. An electrically controlled valve is provided in the air outlet of the wiper blade. At the same time, the air outlet of the wiper blade is tilted downward to blow air.

[0010] Furthermore, the bottom of the dust baffle is in contact with the ground, and the bottom of the dust baffle is smooth. The dust baffle has a semi-enclosed structure, and the top of the dust baffle is connected to the built-in air duct. At the same time, the airflow generated by the air outlet in the dust baffle will form a ring airflow at the bottom of the chassis.

[0011] Furthermore, the cleaning assembly includes a roller groove and a cleaning roller. The roller groove is formed in the outer wall of the bottom of the chassis, and slots for installing the cleaning roller are formed in the center of both sides of the roller groove. At the same time, the slot on one side of the roller groove is connected to the cleaning chamber. The cleaning roller is rotatably connected in the roller groove, and a transmission air passage is formed on the inner wall of the top of the roller groove. One side of the transmission air passage is connected to the built-in air passage in the chassis, and the inner wall of the roller groove on the other side of the transmission air passage is provided with a drain outlet that is unidirectionally connected to the sewage chamber.

[0012] Furthermore, the cleaning roller includes a roller body and a cleaning sleeve. The roller body has a hollow structure inside, and a connecting shaft is fixedly connected to the center of both sides of the roller body. At the same time, the connecting shaft on one side of the roller body has a through hole that communicates with the groove on one side of the roller groove, and an array of water guide ports are provided on the inner wall of the cleaning roller body. The cleaning sleeve is made of elastic rubber and is fitted onto the outside of the roller. Cleaning cotton is fixedly connected to the outer wall of the cleaning sleeve, and a water supply pipe is provided in the inner wall of the cleaning sleeve, which is aligned with the water inlet.

[0013] Furthermore, the action component includes a limiting ring and a power ball.

The power ball is rotatably connected to the center of the limiting ring, and a meshing groove is opened in the center of the power ball body, and a rack is fixedly connected to the side wall on one side of the meshing groove.

[0014] Furthermore, the system operation method is as follows: S1: The robot cleans the ground along the cleaning route according to the system control, and avoids obstacles on the route using obstacle avoidance radar; S2: During the robot's movement, the air pump inside the suction nozzle generates suction to draw debris from the ground into the collection chamber, and transfers excess air to the chassis. The dust baffle creates a spiral airflow in the space at the suction nozzle. S3: During the robot's movement, the cleaning component will wash and mop the floor after vacuuming, and combined with the detector to observe the area of ​​water stains remaining on the floor, it will control whether the air vent in the squeegee is turned on to dry the floor. S4: The built-in air passage in the chassis transmits air to the transmission air passage to clean the outer surface of the cleaning roller. The high-speed airflow transmits the residual sewage and stains on the outer surface of the cleaning roller to the sewage chamber for storage. S5: After the cleaning work is completed, the system will automatically return to the starting point to recharge, drain sewage, and replenish cleaning resources according to the system settings.

[0015] Beneficial effects: 1. The robot is equipped with a chassis, and its internal cleaning fluid and water are replenished through a storage compartment on top and cleaning fluid and water pipes on the inner wall of its rear. The cleaning fluid enters the cleaning chamber for storage along the cleaning fluid pipe. The clean water enters the cleaning chamber for storage through the pipe above the water pipe. When there is sewage in the sewage chamber, the pipe below the water pipe drains the sewage from the robot's interior, thus facilitating the replenishment of the robot's internal cleaning energy.

[0016] 2. The system features a collection chamber. The suction nozzle on the bottom inner wall and the suction pump inside generate suction force to draw dust and debris from the ground into the collection chamber for storage. The air entering the collection chamber is then transmitted through the leaks on the inner walls on both sides of the collection chamber to the exhaust pipe and the built-in air duct inside the chassis. Combined with the semi-enclosed design of the dust baffle, the airflow forms a spiral airflow at the front of the chassis, which facilitates the guidance of dirt to the area below the suction nozzle.

[0017] 3. By incorporating a cleaning component, the mixed cleaning agent is introduced into the roller body via a connecting shaft on one side, and then transferred to the cleaning sleeve through a water inlet. During the robot's movement, the cleaning roller will contact the ground for cleaning. Combined with a damper on the connecting shaft on one side of the roller body, the overall rotation speed of the cleaning roller is controlled, thus avoiding excessive rotation speed of the cleaning roller and reducing the cleaning force on the ground.

[0018] 4. By incorporating a cleaning component, air from the exhaust pipe is transported through a transmission air passage located on the inner wall of the roller trough top. The diameter of this transmission air passage is smaller than that of the chassis's built-in air passage, thus compressing the air and increasing its transmission speed. As the air moves at high speed through the transmission air passage, it agitates the cleaning cotton, pushing and transporting the dirt and adhering wastewater onto the cotton towards the drain inlet and into the wastewater chamber for storage.

Implementation

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example

[0032] As attached Figure 1 To be continued Figure 10 As shown: A cleaning robot and its system include a body 1, a chassis 2, and a motion assembly 3. The body 1 has a hollow cavity with an open bottom, and an obstacle avoidance radar 101 is embedded in the front side wall of the body 1.

An internal air passage is formed in the inner wall of the chassis 2, and an exhaust pipe 211 is connected to both sides of the chassis 2 and the storage cavity 201.

[0033] A dust baffle 215 and a wiper blade 216 are snapped onto the inner wall of the bottom of the chassis 2, and a cleaning assembly 213 is provided on the inner wall of the chassis 2 between the dust baffle 215 and the wiper blade 216. Cleaning liquid pipes 207 and water pipes 208 are respectively connected to the two sides of the back of the storage compartment 201, and the ends of the cleaning liquid pipes 207 and water pipes 208 extend to the outside of the body 1. The storage compartment 201 is divided into a collection chamber 205 and a water storage chamber 202. A suction nozzle 209 extending to the outside of the bottom of the chassis 2 is fixedly connected to the center of the bottom of the collection chamber 205, and an air pump is fixedly connected inside the suction nozzle 209. Filter holes communicating with the exhaust pipe 211 are opened on the top inner walls of both sides of the collection chamber 205.

[0034] A partition 210 is fixedly connected to the center of one side of the water storage chamber 201, and the partition 210 divides the water storage chamber 201 into a sewage chamber 203 and a clean water chamber 204. The clean water chamber 204 and the sewage chamber 203 are respectively connected to the water pipe 208. A cleaning liquid chamber 206 is opened on the other side of the water storage chamber 201, and the cleaning liquid chamber 206 is aligned with the clean water chamber 204. A through hole is opened on the inner wall between the cleaning chamber 206 and the clean water chamber 204. The bottom of the wiper blade 216 is in contact with the ground, and the bottom of the wiper blade 216 is smooth. An air outlet is opened on the outer wall of the front of the wiper blade 216. The top of the wiper blade 216 is connected to the built-in air channel 214, and an electrically controlled valve is installed in the air outlet of the wiper blade 216. The air outlet of the wiper blade 216 is tilted downward.

[0035] The bottom of the dust baffle 215 is flush with the ground and has a smooth bottom surface. The dust baffle 215 has a semi-enclosed structure, and its top is connected to the built-in air duct 214. The airflow generated by the air outlet in the dust baffle 215 will form a ring-shaped airflow at the bottom of the chassis 2. The cleaning assembly 213 includes a roller groove 219 and a cleaning roller 220. The roller groove 219 is opened in the outer wall of the bottom of the chassis 2, and slots for installing the cleaning roller 220 are opened in the center of both sides of the roller groove 219. At the same time, the slot on one side of the roller groove 219 is connected to the cleaning chamber 204. The cleaning roller 220 is rotatably connected in the roller groove 219, and a transmission air duct 221 is opened on the inner wall of the top of the roller groove 219. One side of the transmission air passage 221 is connected to the built-in air passage 214 in the chassis 2, and the inner wall of the roller groove 219 on the other side of the transmission air passage 221 is provided with a drain outlet 222 that is unidirectionally connected to the sewage chamber 203.

[0036] The robotic vacuum cleaner, located in the base station, replenishes its internal components with cleaning fluid and water via cleaning fluid pipes 207 and 208 on its rear inner wall. The cleaning fluid flows along cleaning fluid pipe 207 into the cleaning chamber 206 for storage. The water flows through a pipe above water pipe 208 into the cleaning chamber 204 for storage. When there is wastewater in the wastewater chamber 203, the pipe below water pipe 208 drains the wastewater from the robot's interior. Simultaneously, the robot's internal power supply is charged via a wireless charging module.

[0037] After the robot's energy supplies are replenished, it will move along the planned route and clean the ground along the path. At this time, the suction pump in the suction nozzle 209 will operate, generating suction to draw dust and debris from the ground into the collection chamber 205 for storage. Air entering the collection chamber 205 will be transmitted through perforations on the inner walls of both sides of the collection chamber 205 to the exhaust pipe 211, and then to the built-in air duct 214 inside the chassis 2. Simultaneously, when sticky stains adhere to the ground, the dust baffle 215 on the bottom of the chassis 2 will scrape them off, and the scraped stains will be blown forward by the air outlet in front of the dust baffle 215. The semi-enclosed design of the dust baffle 215 creates a spiral airflow at the front of the chassis 2, facilitating the suction nozzle 209 to draw the stains into the collection chamber 205.

[0038] During the robot's movement, the cleaning fluid in the cleaning fluid chamber 206 will mix with the clean water stored in the clean water chamber 204 through the opening on the inner wall between the cleaning fluid chamber 206 and the clean water chamber 204 to form a mixed cleaning fluid with a low concentration, and then be transferred to the cleaning assembly 213 through the channel in the chassis 2 on one side of the cleaning chamber 204.

[0039] The cleaning roller 220 includes a roller body 223 and a cleaning sleeve 226. The roller body 223 has a hollow internal structure, and connecting shafts 224 are fixedly connected to the center of both sides of the roller body 223. A through hole is provided on one side of the connecting shaft 224 of the roller body 223, communicating with the groove opening on one side of the roller groove 219. An array of water guide ports 225 are provided on the inner wall of the cleaning roller 220. The cleaning sleeve 226 is made entirely of elastic rubber and is fitted onto the outside of the roller body 220. A cleaning cotton 228 is fixedly connected to the outer wall of the cleaning sleeve 226, and a water delivery pipe 227 is provided in the inner wall of the cleaning sleeve 226, aligned with the water guide ports 225.

[0040] The roller 223 receives the mixed cleaning agent through a connecting shaft 224 on one side, and the cleaning agent is transferred to the cleaning sleeve 226 via a water inlet 225 on the roller 223. A water pipe 227 in the cleaning sleeve 226 guides the cleaning solution into the cleaning cotton 228 on the outer surface of the cleaning sleeve 226. During the robot's movement, the cleaning roller 220 contacts the ground for cleaning and rotates upon contact. A damper is installed on the connecting shaft 224 on one side of the roller 223 to control the overall rotation speed of the cleaning roller 220, preventing it from rotating too fast and reducing the cleaning force on the ground.

[0041] The moving component 3 includes a limiting ring 301 and a power ball. The limiting ring 301 has motor compartments 304 on its front and sides, and a drive motor 305 is fixedly connected to each motor compartment 304. The drive motors 305 on both sides of the limiting ring 301 are engaged with guide wheels 303 extending into the steering groove 218, while the drive motor 305 on the front of the limiting ring 301 is engaged with guide wheels 303 extending inwards from the limiting ring 301. The power ball 302 is rotatably connected to the center of the limiting ring 301, and a meshing groove 306 is formed at the center of the power ball 302. A rack 307 is fixedly connected to the side wall of one side of the meshing groove 306.

[0042] During movement, the robot's guide wheel 303 is driven to rotate by the drive motor 305 at the center of the limiting ring 301. This causes the guide wheel 303 to rotate in the meshing groove 306 at the center of the power ball 302 and mesh with the rack 307, thus driving the robot to rotate and enabling the robot to move in a directional manner. Simultaneously, when the robot needs to turn or make minor path adjustments, the control terminal adjusts the orientation of the motion components 3 at the four corners of the chassis 2. This causes the limiting ring 301 to move in the steering groove 218 with the cooperation of the drive motors 305 on both sides and the guide wheel 303, changing the angle of movement of one or more motion components 3, thereby changing the robot's direction of movement. Example

[0043] As attached Figure 6 To be continued Figure 7 As shown: The cleaning roller 220 includes a roller body 223 and a cleaning sleeve 226. The roller body 223 has a hollow internal structure, and connecting shafts 224 are fixedly connected to the center of both sides of the roller body 223. A through hole is provided on one side of the connecting shaft 224 of the roller body 223, communicating with the groove opening on one side of the roller groove 219. An array of water guide ports 225 are provided on the inner wall of the cleaning roller 220. The cleaning sleeve 226 is made entirely of elastic rubber and is fitted onto the outside of the roller body 220. A cleaning cotton 228 is fixedly connected to the outer wall of the cleaning sleeve 226, and a water delivery pipe 227 is provided in the inner wall of the cleaning sleeve 226, aligned with the water guide ports 225.

[0044] The transmission air passage 221 in the inner wall of the top of the roller trough 219 transmits air from the exhaust pipe 211 into it. Since the diameter of the transmission air passage 221 is smaller than the diameter of the built-in air passage 214 in the chassis 2, the air is compressed, increasing the air transmission speed. As the air moves at high speed in the transmission air passage 221, it blows the cleaning cotton 228, thereby pushing the dirt and adhering wastewater on the cleaning cotton 228 towards the guide inlet 225 and transmitting it to the wastewater chamber 203 for storage. The air entering the wastewater chamber 203 is discharged through the exhaust hole at the top of one side of the wastewater chamber 203. Example

[0045] As attached Figure 11 As shown: The system operation steps are as follows: S1: The robot cleans the ground along the cleaning route according to the system control, and avoids obstacles on the route using obstacle avoidance radar; S2: During the robot's movement, the air pump inside the suction nozzle generates suction to draw debris from the ground into the collection chamber, and transfers excess air to the chassis. The dust baffle creates a spiral airflow in the space at the suction nozzle. S3: During the robot's movement, the cleaning component will wash and mop the floor after vacuuming, and combined with the detector to observe the area of ​​water stains remaining on the floor, it will control whether the air vent in the squeegee is turned on to dry the floor. S4: The built-in air passage in the chassis transmits air to the transmission air passage to clean the outer surface of the cleaning roller. The high-speed airflow transmits the residual sewage and stains on the outer surface of the cleaning roller to the sewage chamber for storage. S5: After the cleaning work is completed, the system will automatically return to the starting point to recharge, drain sewage, and replenish cleaning resources according to the system settings.

[0046] Working principle: The robotic vacuum cleaner replenishes its internal components with cleaning fluid and water via cleaning fluid pipe 207 and water pipe 208 on its rear inner wall within the base station. The cleaning fluid flows along cleaning fluid pipe 207 into the cleaning chamber 206 for storage. Water flows through a pipe above water pipe 208 into the cleaning chamber 204 for storage. When there is wastewater in the wastewater chamber 203, the pipe below water pipe 208 drains the wastewater from the robot's interior. The robot's internal power supply is charged via a wireless charging module. After the robot's energy supply is completed, the robot drives the guide wheel 303 to rotate via the drive motor 305 at the center of the limit ring 301. This causes the guide wheel 303 to rotate in the meshing groove 306 at the center of the power ball 302 and mesh with the rack 307, thus causing the robot to rotate and move in a directional manner. When the robot needs to turn or make minor adjustments to its path, the control terminal will adjust the position of the motion components 3 at the four corners of the bottom of the chassis 2. This causes the limit ring 301 to move in the steering groove 218 with the cooperation of the drive motors 305 on both sides and the guide wheel 303, changing the angle of movement of one or more motion components 3, thereby changing the robot's direction of movement and cleaning the ground along its path.

[0047] The suction pump in the suction nozzle 209 of the robot chassis will generate suction force to draw dust and debris from the ground into the collection chamber 205 for storage. Air entering the collection chamber 205 will be transmitted through perforations on the inner walls of both sides of the collection chamber 205 to the exhaust pipe 211, and then to the built-in air duct 214 inside the chassis 2. When sticky stains adhere to the ground, the dust baffle 215 on the bottom of the chassis 2 will scrape them off, and the scraped stains will be blown forward by the air outlet in front of the dust baffle 215. The semi-enclosed design of the dust baffle 215 creates a spiral airflow at the front of the chassis 2, making it easier for the suction nozzle 209 to draw the stains into the collection chamber 205.

[0048] During the robot's movement, its internal cleaning roller 220 will contact the ground to clean it, and will rotate when in contact with the ground. A damper is provided on the connecting shaft 224 on one side of the roller body 223 to control the overall rotation speed of the cleaning roller 220. If the ice surface cleaning roller 220 rotates too fast, it will reduce the cleaning force on the ground.

[0049] After the cleaning roller 220 cleans the floor, as it rotates to the top of the roller trough 219, the transmission air passage 221 in the inner wall of the top of the roller trough 219 transmits air from the exhaust pipe 211 into it. Since the diameter of the transmission air passage 221 is smaller than the diameter of the built-in air passage 214 in the chassis 2, the air is compressed, increasing the air transmission speed. As the air moves at high speed in the transmission air passage 221, it blows the cleaning cotton 228, thereby pushing the dirt and adhering wastewater on the cleaning cotton 228 towards the guide inlet 225 and transmitting it to the wastewater chamber 203 for storage. The air entering the wastewater chamber 203 is discharged through the exhaust hole at the top of one side of the wastewater chamber 203, thus cleaning the outer surface of the cleaning cotton 228 and improving the cleaning effect on the floor.
