[0030] This invention proposes a base station that is used in conjunction with a cleaning robot. The base station can not only clean the cleaning components (mop, roller brush, etc.) on the cleaning robot, but also charge the cleaning robot, add cleaning fluid to the cleaning robot, and perform other tasks on the cleaning robot, which will not be listed here.

[0031] It is worth noting that there are various types of cleaning robots mentioned above. These cleaning robots can be sweeping robots, mopping robots, or even integrated sweeping and mopping robots. They can also be other types of cleaning robots. No specific limitation is made on the type of cleaning robot here.

[0032] Please see together Figures 1 to 2The base station 100 includes a base station body 110, a suction and processing device 120, and a waste storage tank 130. The suction and processing device 120 and the waste storage tank 130 are installed on the base station body 110. The suction and processing device 120 is used to pulverize solid waste from the cleaning robot 200 and suck the pulverized solid and liquid waste into the waste storage tank 130. The base station body 110 can have various shapes, such as L-shaped, I-shaped, wedge-shaped, and others, without specific limitations. The base station body 110 can be made of metal, high-hardness plastic, or other materials, without specific limitations.

[0033] The base station body 110 has a parking space 111 for the cleaning robot 200 to dock. The parking space 111 refers to the area on the base station body 110 where the cleaning robot 200 can be parked. The parking space 111 is mainly used to support the cleaning robot 200. The cleaning robot 200 can be parked completely on the parking space 111, or it can be partially located on the parking space 111. There is no limitation on the specific way the cleaning robot 200 is parked. The parking space 111 can have various shapes, such as being flat or wedge-shaped. There is no specific limitation, as long as the parking space 111 can support the cleaning robot 200. The parking space 111 can be formed by recessing the surface of the base station body 110. The parking space 111 can also be installed on the base station body 110 in a detachable manner. Preferably, the parking space 111 is installed on the base station body 110 in a detachable manner, so that the parking space 111 can be removed as needed, thereby facilitating the cleaning of the parking space 111.

[0034] There are various types of parking spaces 111. The parking space 111 can be an open parking space 111, a semi-enclosed parking space 111, or a fully enclosed parking space 111.

[0035] The open parking space 111 is in a completely open state. The open parking space 111 only provides support for the cleaning robot 200 and does not impose constraints on the cleaning robot 200 in other directions. Specifically, the open parking space 111 can be formed by a plane extending horizontally on the base station body 110, or it can be formed by a plane inclined vertically on the base station body 110. No specific limitation is made here.

[0036] The semi-enclosed parking bay 111 is partially open. It not only provides support for the cleaning robot 200 but also imposes constraints on the robot in other directions. For example, a portion of the side surface of the base station body 110 is recessed to form a cleaning chamber with an open side end, and the space inside the cleaning chamber forms the semi-enclosed parking bay 111. Alternatively, the upper surface of the base station body 110 can also be partially recessed downwards to form a cleaning chamber with an open upper end, thus creating the semi-enclosed parking bay 111.

[0037] The fully enclosed parking bay 111 is completely enclosed. After the cleaning robot 200 is parked, the fully enclosed parking bay 111 is completely closed, so that the cleaning robot 200 is in a completely enclosed environment. Compared with the semi-enclosed parking bay 111, the fully enclosed parking bay 111 adds a door to the semi-enclosed parking bay 111. There can be one or more doors, and the doors can open or close the space where the parking bay 111 is located.

[0038] When the base station 100 is equipped with a charging electrode, the charging electrode includes a positive charging electrode and a negative charging electrode. The positive charging electrode and the negative charging electrode can be two contacts that are spaced apart in the horizontal or vertical direction, or they can be spaced apart inside and outside. There are no restrictions on the installation of the positive charging electrode and the negative charging electrode.

[0039] The suction processing device 120 is installed on the base station body 110. There are many ways to install the suction processing device 120 on the base station body 110. The suction processing device 120 can be installed on the base station body 110 by screw connection, the suction processing device 120 can also be installed on the base station body 110 by snap connection, and the suction processing device 120 can also be installed on the base station body 110 by other methods. No specific limitation is made here.

[0040] The waste collection box 130 is installed on the base station body 110. There are many ways to install the waste collection box 130 on the base station body 110. It can be installed using screws, clips, or other methods; no specific limitation is made here. The waste collection box 130 can also have various shapes, including cylindrical, cuboid, or other shapes; no specific limitation is made here.

[0041] The suction and processing device 120 is installed on the base station body 110. The suction and processing device 120 has a suction port 121 and a discharge port 122. The suction port 121 is used to collect solid and liquid waste cleaned by the cleaning robot 200. The discharge port 122 is connected to the waste storage tank 130. The location of the discharge port 122 can vary; it can be located inside the waste storage tank or on the surface of the waste storage tank 130. No specific limitation is made here.

[0042] The technical solution of this invention employs a suction and processing device 120 installed on the base station 100. This device 120 is mounted on the base station body 110 and has a suction port 121 and a discharge port 122. The suction port 121 collects solid and liquid waste cleaned by the cleaning robot 200, while the discharge port connects to a waste storage tank 130. The suction and processing device 120 pulverizes the solid waste before pumping it into the waste storage tank 130. This configuration allows the suction and processing device 120 to not only pump solid and liquid waste from the cleaning robot 200 but also pulverize solid waste, thereby optimizing the structure of the base station 100 and improving the overall assembly efficiency of the base station 100.

[0043] In some embodiments of the present invention, please refer to the accompanying document. Figures 3 to 5 The suction and treatment device 120 includes a pipe 123, a fan blade 124, and a drive motor 125. The pipe 123 is provided with a suction port 121 and a discharge port 122. The drive motor 125 is fixedly installed inside the pipe 123. The fan blade 124 is fixedly connected to the output shaft of the drive motor 125. Under the drive of the drive motor 125, the fan blade 124 drives the airflow and crushes the solid waste sucked into the pipe 123. With this configuration, the fan blade 124 can crush the solid waste and discharge the crushed solid waste into the waste storage tank 130, thereby optimizing the structure of the base station 100 and improving the assembly efficiency of the entire base station 100.

[0044] The duct 123 can take many forms. It can be formed from the base station body 110, or it can be installed on the base station body 110 in a detachable manner. It can also be partially formed from the base station body 110 and partially installed on it in a detachable manner; no specific limitation is made here. The fan blade 124 can be made from various materials. It can be made of metal and high-hardness plastic, or it can be made of high-hardness plastic, or it can be made of other materials; no specific limitation is made here. The drive motor 125 can be of various types. It can be a hydraulic motor, a high-speed motor, or a pneumatic motor; no specific limitation is made here.

[0045] In some embodiments of the present invention, please refer to the accompanying document. Figures 3 to 5 The fan blade 124 includes a connecting shaft 124a and at least one blade 124b. The connecting shaft 124a is fixedly connected to the output shaft of the drive motor 125. Each blade 124b is connected to the peripheral wall of the connecting shaft 124a and is arranged at intervals along the circumference of the connecting shaft 124a. Each blade 124b has a cutting edge 124c on its windward side and / or on its side away from the connecting shaft 124a. This arrangement helps the blade 124b to crush garbage when rotating, thereby improving the efficiency of the fan blade 124 in crushing garbage.

[0046] There are many ways to form the cutting edge 124c. The cutting edge 124c can be formed by concave grinding on the side of the blade 124b facing the wind and / or the side away from the connecting shaft 124a. The cutting edge 124c can also be formed by convex grinding on the side of the blade 124b facing the wind and / or the side away from the connecting shaft 124a. The cutting edge 124c can also be formed by large flat grinding on the side of the blade 124b facing the wind and / or the side away from the connecting shaft 124a. No specific limitation is made here.

[0047] Considering that the garbage inside the cleaning robot 200 may contain hard solid debris, the fan blades 124 may not be hard enough to crush these hard solid debris during rotation, potentially even causing damage to the fan blades 124. Therefore, please refer to the following... Figures 3 to 5The fan blade 124 includes a connecting shaft 124a and at least one blade 124b. The connecting shaft 124a is fixedly connected to the output shaft of the drive motor 125. Each blade 124b is connected to the peripheral wall of the connecting shaft 124a and is arranged at intervals along the circumference of the connecting shaft 124a. At least one blade 124b is made of metal. With this arrangement, the high hardness of the metal material allows the blade 124b to crush harder solid waste when rotating, and the metal material is not easily worn, which improves the service life of the blade 124b.

[0048] The connecting shaft 124a can have various shapes, including cylindrical, stepped, and hemispherical. No specific limitations are made here. The connecting shaft 124a can also be made of various materials, including metal and hard plastic. No specific limitations are made here. The connecting shaft 124a can be fixedly connected to the output shaft of the drive motor 125 in various ways. It can be connected by a key, a pin, or other methods. No specific limitations are made here.

[0049] Considering that the different materials used to form the blades 124b result in different weights, the center of gravity of the fan blade 124 is not on the output shaft of the drive motor 125 when it rotates. This causes the drive motor 125 to vibrate, thus affecting the suction and pulverizing effects of the suction processing device 120. Therefore, the number of blades 124b is at least two, and the two symmetrically arranged blades 124b are both made of metal. For this arrangement, please refer to [reference needed]. Figure 5 The symmetrical blades 124b are made of metal so that the center of gravity of the fan blades 124 is on the output shaft of the drive motor 125 when they rotate, thereby avoiding vibration of the drive motor 125, which in turn allows the suction and processing device 120 to operate stably and improves the suction and crushing effect of the suction and processing device 120.

[0050] Considering that when the output end of the drive motor 125 is exposed outside the pipe 123, it is easy for waste to be drawn into the output end from the exposed part. This can easily lead to a decrease in the output efficiency of the drive motor 125 or even damage to the drive motor 125, thereby causing the suction processing device 120 to malfunction. Therefore, please refer to... Figure 5The outer diameter of the connecting shaft 124a is larger than the outer diameter of the drive motor 125. With this configuration, the connecting shaft 124a can effectively cover the output end of the drive motor 125, thereby preventing the drive motor 125 from being affected by garbage.

[0051] Considering that base station 100 may need to clean the cleaning components of cleaning robot 200, the suction port 121 of suction processing device 120 needs to clean the cleaning wastewater. Simultaneously, the suction port 121 of suction processing device 120 also needs to clean the solid waste from cleaning robot 200. Therefore, please refer to... Figure 3 The sludge suction port 121 of the pipe 123 includes a solid waste collection port 121a and a liquid waste collection port 121b. The fan blade 124 and the drive motor 125 are installed inside the pipe 123 to drive air to flow from the solid waste collection port 121a to the sludge discharge port 122. The parking station 111 has a recessed cleaning tank 111a on the side facing the cleaning robot 200. The base station 100 also includes a water pump 126. The water outlet of the water pump 126 is connected to the pipeline of the liquid waste collection port 121b, and the water inlet of the water pump 126 is connected to the cleaning tank 111a.

[0052] With this configuration, the cleaning wastewater from the cleaning robot 200 cleaned by the base station 100 will collect in the cleaning tank 111a, thus avoiding pollution of the environment by the cleaning wastewater. At the same time, the cleaning wastewater will be drawn by the water pump 126 and enter the liquid waste collection port 121b of the pipe 123 through the pipeline. The solid waste from the cleaning robot 200 will enter the solid waste collection port 121a of the pipe 123 under the drive of the fan blade 124 and the drive motor 125. Finally, the solid waste and cleaning wastewater will enter the wastewater storage tank 130 through the sewage outlet 122 of the pipe 123. In this way, the base station 100 can clean the solid waste and cleaning wastewater from the cleaning robot 200 at the same time.

[0053] It should be noted that there are many types of water pump 126. Water pump 126 can be a centrifugal pump, water pump 124b vane pump, water pump 126 can also be a vacuum pump, and no specific limitation is made here.

[0054] In some embodiments of the present invention, please refer to Figure 5The pipe 123 includes a solid waste inlet section 123a, a liquid waste inlet section 123b, and a sewage discharge section 123c arranged in parallel in the vertical direction. The lower end of the solid waste inlet section 123a forms a solid waste collection port 121a, and the upper end of the solid waste inlet section 123a is connected to the upper end of the sewage discharge section 123c. One end of the liquid waste inlet section 123b is connected to the middle of the sewage discharge section 123c, and the end of the liquid waste inlet section 123b away from the sewage discharge section 123c forms a liquid waste collection port 121b. The lower end of the sewage discharge section 123c forms a sewage discharge port 122. The fan blade 124 and the drive motor 125 are located on the side of the sewage discharge section 123c near the sewage discharge port 122.

[0055] With this setup, after the cleaning robot 200 stops at parking station 111, the solid waste from the cleaning robot 200 will enter the solid waste collection port 121a of pipe 123 under the drive of fan blade 124 and drive motor 125. At the same time, the cleaning wastewater will be drawn by water pump 126 and enter the liquid waste collection port 121b of pipe 123 through the pipeline. Since the fan blade 124 and drive motor 125 are located between the drain port 122 and the liquid waste collection port 121b, the cleaning wastewater will pass through the fan blade 124 and drive motor 125 and then through the drain port 122 into the waste storage tank 130. This allows the cleaning wastewater to wash away the solid waste attached to the inner wall of the fan blade 124 and the drain section 123c, thereby avoiding the accumulation of waste on the inner wall of the fan blade 124 and the drain section 123c, which would require manual cleaning, thus improving the user experience.

[0056] It should be noted that the solid waste inlet section 123a is divided into an upper end and a lower end along the direction towards the ground, and the waste discharge section 123c is divided into an upper end, a middle section and a lower end along the direction towards the ground.

[0057] In some embodiments of the present invention, the pipe 123 has at least a drain section 123c extending vertically. The fan blade 124 and the drive motor 125 are disposed within the drain section 123c. The base station 100 also includes a water spray nozzle 140, which is disposed within the drain section 123c and located above the fan blade 124. The water spray nozzle 140 is used to spray water onto the inner peripheral wall of the fan blade 124 and / or the drain section 123c. With this configuration, the water spray nozzle 140 can spray water onto the inner wall of the fan blade 124 and / or the drain section 123c to clean up the debris adhering to the inner wall of the fan blade 124 and / or the drain section 123c, thereby preventing the accumulation of debris on the inner wall of the fan blade 124 or the drain section 123c and reducing the suction efficiency of the suction treatment device 120. At the same time, it can also reduce the number of times manual cleaning is required and improve the user experience.

[0058] There are many types of water spray nozzles 140. The water spray nozzle 140 can be a diffuser nozzle, a stationary nozzle, or a spray nozzle. No specific limitation is made here.

[0059] In some embodiments of the present invention, please refer to Figure 5 The inner peripheral wall of the sewage discharge section 123c is provided with an annular pipe 123d extending circumferentially thereon. Water spray nozzles 123e are formed on the annular pipe 123d and distributed circumferentially along the sewage discharge section 123c. The sewage discharge section 123c also has a water inlet 123f. The outlet end of the water inlet 123f is connected to the annular pipe 123d, and the inlet end of the water inlet 123f is connected to the water source pipeline. With this configuration, when water flows through the annular pipe 123d, water can be evenly sprayed onto the inner peripheral wall of the sewage discharge section 123c through the circumferentially distributed water spray nozzles 123e, thereby improving the cleaning efficiency of the water spray head 140 on the inner peripheral wall of the sewage discharge section 123c.

[0060] It should be noted that the water source can be water stored in the water storage chamber formed by the base station body 110, or water obtained through a connection to a faucet pipe. Preferably, the water source is water stored in the water storage chamber formed by the base station body 110, thus allowing the base station 100 to operate without a water source, thereby expanding its application range. The water storage chamber can have various shapes; it can be cylindrical, cuboid, or other shapes, without specific limitations. The water storage chamber can be formed by a cavity structure on the base station body 110, or it can be formed by a box structure, without specific limitations. Preferably, the water storage chamber is formed by a detachable box structure, allowing the box structure to be removed as needed for easy cleaning of the interior space of the water storage chamber.

[0061] The water source can be purified water or disinfected water. Preferably, the water source is disinfected water, so that the inner wall of the sewage discharge section 123c and / or the fan blades 124 can be disinfected to prevent bacterial growth.

[0062] In some embodiments of the present invention, the surface of the sludge storage tank 130 near the suction processing device 120 is recessed with a relief groove 131, and the suction processing device 120 is located in the relief groove 131. With this arrangement, the suction processing device 120 is exposed outside the base station body 110, which is beneficial to the assembly and maintenance of the suction processing device 120, and at the same time reduces the space occupied by the suction processing device 120 in the base station body 110, thereby optimizing the structure of the base station 100.

[0063] To further improve the user experience, this invention also proposes a control method for a base station 100, which further includes a controller electrically connected to the suction processing device 120. The control method for the base station includes: Receive the signal that the cleaning robot 200 has stopped at parking station 111; The suction and processing device 120 is activated to suction solid waste from the cleaning robot 200. The control suction and processing device 120 crushes the solid waste and then pumps it into the sludge storage tank 130; Stop the suction and treatment device 120 from operating and clean the cleaning parts of the cleaning robot 200 to form liquid waste; Stop the cleaning operation and start the suction treatment device 120 to suck the liquid waste into the sludge storage tank 130.

[0064] With this configuration, after the suction and treatment device 120 finishes suctioning the solid waste in the cleaning robot 200, some solid waste will remain in the suction and treatment device 120. By suctioning the wastewater, the solid waste remaining in the suction and treatment device 120 will be cleaned into the waste storage tank 130, thereby avoiding the need for users to clean up the solid waste remaining in the suction and treatment device, and thus improving the user experience.

[0065] Specifically, the controller can be a microcontroller, a PWM controller, a microprocessor, or other devices. The controller is electrically connected to the suction processing device 120, and the controller and the suction processing device 120 can be electrically connected via wires. The controller and the suction processing device 120 can also communicate wirelessly via methods such as Wi-Fi or Bluetooth; no specific limitations are specified here. The controller can also be electrically connected to the cleaning robot 200 via wires, and the controller and the cleaning robot 200 can also communicate wirelessly via methods such as Wi-Fi or Bluetooth; no specific limitations are specified here.

[0066] There are many ways to obtain the signal that the cleaning robot 200 has stopped at the parking station 111. The signal can be obtained by the cleaning robot 200 contacting the charging electrode on the parking station 111, or by the cleaning robot 200 pressing the positioning protrusion on the parking station 111. No specific limitation is made here.

[0067] In some embodiments of the present invention, the suction processing device includes a pipe 123, a fan blade 124, and a drive motor 125. The pipe 123 connects a sludge storage tank 130 and a sludge suction port 121. The drive motor 125 is installed inside the pipe 123. The fan blade 124 is fixedly connected to the output shaft of the drive motor 125. The control method for controlling the suction processing device 120 to pulverize solid waste and then suck it into the sludge storage tank 130 includes: The drive motor 125 is controlled to drive the fan blade 124 to rotate, thereby driving airflow to suck solid waste in the cleaning robot 200 into the pipe 123. The control fan blade 124 crushes the solid waste passing through the pipe 123 and then sucks it into the sludge storage tank 130.

[0068] With this configuration, the fan blades 124 can pulverize solid waste and discharge the pulverized solid waste into the waste storage tank 130, thereby optimizing the structure of the base station 100 and improving the assembly efficiency of the entire base station 100.

[0069] In some embodiments of the present invention, the parking station 111 is recessed with a cleaning tank 111a on the side facing the cleaning robot 200. The suction and processing device 120 further includes a water pump 126, the outlet of which is connected to a pipe 123, and the inlet of which is connected to the cleaning tank 111a. The step of stopping the cleaning operation and starting the suction and processing device 120 to suck the liquid waste into the sludge storage tank 130 includes: Stop the cleaning operation and start the water pump 126 to pump the liquid waste in the cleaning tank 111a along the pipe 123 to the sludge storage tank 130.

[0070] With this configuration, the water pump 126 stops working when the drive motor 125 is operating, thereby preventing the liquid waste pumped by the water pump 126 from affecting the rotation of the fan blade 124, and thus preventing the solid waste inside the cleaning robot from not being cleaned properly. At the same time, the water pump 126 can start working again after the drive motor 125 stops working, so that the liquid waste can clean the solid waste attached to the inner wall of the fan blade 124 and the pipe 123.

[0071] In some embodiments of the present invention, the base station 100 further includes a water spray nozzle 140. After stopping the cleaning operation and starting the water pump 126 to pump the liquid waste into the sludge storage tank 130, the following steps are also included: Stop the water pump 126 and start the water spray head to clean the inner wall of the pipe 123 and / or the fan blade 124.

[0072] This design avoids the accumulation of solid debris on the inner wall of the duct 123 and / or the fan blades 124 after the base station 100 stops working, thus avoiding user intervention in cleaning and improving the user experience.

[0073] This invention proposes a cleaning machine system 1000; please refer to [link / reference]. Figure 2 The cleaning machine system 1000 includes a cleaning robot 200 and a base station 100. The specific structure of the base station 100 is as described in the above embodiments. Since the cleaning machine system 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
