[0054] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0056] It should be noted that the terms "setting," "installing," and "connecting" in the embodiments of this invention should be interpreted broadly. Those skilled in the art can reasonably determine the specific meaning of the above terms in the embodiments of this invention in conjunction with the specific content of the technical solution. For example, the term "connection" can be a mechanical connection, an electrical connection, or a connection that allows for mutual communication; it can be a direct connection or an indirect connection through an intermediate medium.

[0057] It should be noted that the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0058] Robotic vacuum cleaners, also known as automatic cleaning machines, smart vacuum cleaners, or robotic vacuums, are a type of smart home appliance. Leveraging artificial intelligence, they can automatically clean floors throughout a room. With technological advancements, robotic vacuum cleaners have gradually become a part of people's daily lives as a cleaning system. After collecting a significant amount of dust and debris during floor cleaning, the dustbin of a robotic vacuum cleaner needs to be emptied. Currently, some robotic vacuum cleaners require manual emptying of the dustbin, while others return to a base station for automatic cleaning. However, both methods generally suffer from poor dust collection efficiency, often leaving small pieces of paper, lint, and other debris inside.

[0059] Based on this, embodiments of the present invention provide a cleaning system that can improve the dust collection effect of the base station on the cleaning robot.

[0060] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0061] An embodiment of the present invention provides a cleaning system, referring to Figure 1 As shown, the cleaning system includes a cleaning robot 100 and a base station 200, wherein:

[0062] Reference Figure 3 and Figure 5 The cleaning robot 100 includes a roller brush 110, a dust box 120 and a main fan. The dust box 120 is provided with a dust box suction port 121 communicating with the roller brush 110, a first outlet 122 communicating with the main fan, and a second outlet 123 for discharging dust from inside the dust box 120.

[0063] Base station 200 includes a base station fan for collecting dust from inside dust box 120 from second outlet 123 when cleaning robot 100 is docked at base station 200;

[0064] Specifically: When the cleaning robot 100 docks at the base station 200, it controls both the main unit fan and the base station fan to start during the first time period. During the second time period, it controls the main unit fan to stop while keeping the base station fan running. After the second time period, it controls both the main unit fan and the base station fan to stop. It can be understood that the second time period follows the first time period. Furthermore, the cleaning robot 100 is typically equipped with a main unit controller, and the base station 200 is equipped with a base station controller. Therefore, the main unit fan is generally controlled by the main unit controller on the cleaning robot 100, and the base station fan is generally controlled by the base station controller on the base station 200. Thus, the coordinated control of the main unit fan and the base station fan requires communication and coordination between the main unit controller and the base station controller.

[0065] According to the cleaning system provided in this embodiment of the invention, when the cleaning robot 100 moves to the outside to clean the ground, under the negative pressure generated by the main fan, a suction airflow circuit is formed that flows sequentially through the roller brush 110, the dust box suction port 121, the interior of the dust box 120, the first outlet 122 of the dust box 120, and the main fan, so that dust is collected inside the dust box 120. When there is a lot of dust and debris inside the dust box 120, after the cleaning robot 100 returns to the base station 200, the base station fan, together with the main fan, transfers the dust and debris inside the dust box 120 to the base station 200. Specifically, the main fan and the base station fan are turned on simultaneously in the first time period. Under the negative pressure, a dust collection circuit is formed, flowing from inside the dust box 120 through the second outlet 123 of the dust box 120 to the dust collection device in the base station 200. At the same time, a suction airflow circuit is also formed by the opening of the main fan, which makes it easier for dust and garbage inside the dust box 120 to be discharged under the turbulence of the suction airflow circuit. Then, in the second period, the main fan is controlled to be turned off, and only the negative pressure generated by the base station fan collects the dust and garbage inside the dust box 120. This avoids light paper scraps, lint, etc. being adsorbed at the first outlet 122 due to the negative pressure generated by the main fan and not being carried away by the negative pressure generated by the base station fan, which can effectively improve the dust collection effect of the base station 200 on the cleaning robot 100.

[0066] It is understandable that the base station fan is located inside base station 200. Further reference... Figure 2 In the cleaning system provided in some embodiments of the present invention, the base station 200 is provided with a dust collection port 210 that generates negative pressure when the base station fan is turned on; see reference Figure 3 The cleaning robot 100 is equipped with a dust collection duct 130. One end of the dust collection duct 130 located inside the cleaning robot 100 is used to connect with the second outlet 123, and the other end of the dust collection duct 130 located outside the cleaning robot 100 is used to connect with the dust collection port 210.

[0067] Combination Figure 7 As shown in the airflow circuit diagram, the dust suction airflow circuit formed when the main unit fan is turned on is as follows: Figure 7 As shown by the solid arrow, the airflow carrying dust passes through the roller brush 110 and enters the dustbin 120 through the dustbin suction port 121, then flows to the main fan from the first outlet 122 of the dustbin 120. It is understood that a filter is installed at the first outlet 122 of the dustbin 120, which traps dust, paper scraps, lint, and other debris carried in the airflow inside the dustbin 120. The airflow then passes through the main fan and is finally discharged from the outlet of the main fan to the outside of the cleaning robot 100. Additionally, the dust collection circuit formed when the base station fan is turned on is as follows... Figure 7As shown by the dotted arrow, the dust, paper scraps, lint, etc. inside the dust box 120 flow from the second outlet 123 of the dust box 120 to the dust collection duct 130, and finally from the dust collection port 210 of the base station 200 to the dust collection device inside the base station 200.

[0068] Understandably, due to size and space constraints, the dustbin 120 of the cleaning robot 100 is generally not very large, while the base station 200 can be made larger. Therefore, the base station 200 can have a larger dust collection device inside, such as a dust bag or dust collection box. When the cleaning robot 100 is cleaning the floor, if there is a lot of dust, paper scraps, lint, etc. collected in the dustbin 120, it can return to the base station 200, where the base station fan, together with the main unit fan, will transfer the dust and debris inside the dustbin 120 to the base station 200, and then the floor cleaning work can be carried out again.

[0069] In the cleaning system provided in some embodiments of the present invention, during the first period, the speed of the main fan is switched to change the airflow inside the dust box 120. It is understood that the change in airflow inside the dust box 120 can help to stir up the dust and debris inside the dust box 120, and prevent dust and debris in the corners inside the dust box 120 from not being sucked away due to an overly stable airflow.

[0070] In the cleaning system provided in some embodiments of the present invention, during a first time period, the speed of the main fan is sequentially switched to a first speed setting, a second speed setting, and back to the first speed setting; the airflow speed of the second speed setting is greater than or less than the airflow speed of the first speed setting. It is understood that when the airflow speed of the second speed setting is greater than the airflow speed of the first speed setting, the main fan speed setting first switches from a low speed setting to a high speed setting, and then switches back from a high speed setting to a low speed setting, thereby changing the airflow inside the dust box 120; when the airflow speed of the second speed setting is less than the airflow speed of the first speed setting, the main fan speed setting first switches from a high speed setting to a low speed setting, and then switches back from a low speed setting to a high speed setting, thereby changing the airflow inside the dust box 120; both of these situations can achieve the same effect and function. It should be noted that the above two modes of switching the main fan are only two preferred switching schemes. In actual applications, there can be other switching schemes, such as switching from the first fan speed to the second fan speed, then from the second fan speed to the third fan speed, then from the third fan speed to the fourth fan speed, and finally switching back to the first fan speed in sequence.

[0071] In this embodiment, by controlling the main fan to switch between high speed and low speed during the first period of the main fan's operation, a turbulent airflow is generated inside the dust box 120, which helps to stir up the dust and debris inside the dust box 120 and avoids the dust and debris in the corners of the dust box 120 not being sucked away due to an overly stable airflow.

[0072] In the cleaning system provided in some embodiments of the present invention, the speed of the base station fan is switched during a first or second time period to change the airflow inside the dust box 120. Similarly, switching the speed of the base station fan can also change the airflow inside the dust box 120, thereby helping to stir up the dust and debris inside the dust box 120 and preventing dust and debris in the corners of the dust box 120 from being unable to be sucked away due to overly stable airflow.

[0073] In the cleaning system provided in some embodiments of the present invention, during a first or second time period, the speed of the base station fan is sequentially switched to a first speed, a second speed, and a first speed again; the wind speed of the second speed is greater than or less than the wind speed of the first speed. Similarly, when the wind speed of the second speed is greater than the wind speed of the first speed, the speed of the base station fan first switches from a low speed to a high speed, and then switches from a high speed to a low speed, thereby changing the airflow inside the dust box 120; when the wind speed of the second speed is less than the wind speed of the first speed, the speed of the base station fan first switches from a high speed to a low speed, and then switches from a low speed to a high speed, thereby changing the airflow inside the dust box 120; both of these situations can achieve the same effect and function.

[0074] Similarly, in this embodiment, by controlling the base station fan to switch between high speed and low speed during the first and second periods of the base station fan's operation, turbulent airflow is generated inside the dust box 120 and in the dust collection circuit. This helps to lift dust and debris inside the dust box 120 and at the corners of the dust collection circuit, preventing the dust and debris in the corners of the dust box 120 from not being sucked up due to overly stable airflow, and preventing light paper scraps and lint from adhering to the filter screen at the first outlet 122 of the dust box 120 and not being sucked up.

[0075] In the cleaning system provided in some embodiments of the present invention, the roller brush 110 is controlled to rotate during a first or second time period.

[0076] In this embodiment, during the first or second period when the base station fan is turned on to collect dust at the base station 200, the roller brush 110 is controlled to rotate so that the dust, paper scraps and lint adsorbed on the roller brush 110 can be carried away into the dust box 120 as the roller brush 110 rotates, and further sucked away by the negative pressure generated by the base station fan; moreover, the rotation of the roller brush 110 can also bring airflow disturbance and vibration of the body of the cleaning robot 100, which is conducive to the discharge of debris in the dust box 120.

[0077] It is understandable that, in the first time period, the operations of controlling the main unit fan to switch its speed sequentially to the first, second, and first speed settings, the operations of controlling the base station fan to switch its speed sequentially to the first, second, and first speed settings, and the operations of controlling the rotation of the roller brush 110, can be performed alternately or simultaneously. Similarly, in the second time period, the operations of controlling the base station fan to switch its speed sequentially to the first, second, and first speed settings, and the operations of controlling the rotation of the roller brush 110, can be performed alternately or simultaneously. Specifically, it is preferable that the above operations be performed simultaneously, which can produce a better dust collection effect.

[0078] In the cleaning system provided in some embodiments of the present invention, in a first time period, the rotational speed of the roller brush 110 is positively correlated with the rotational speed of the main fan or the base station fan; or, in a second time period, the rotational speed of the roller brush 110 is positively correlated with the rotational speed of the base station fan. Specifically, when the rotational speed of the roller brush 110 is positively correlated with the rotational speed of the main fan, the higher the rotational speed of the main fan, the higher the rotational speed of the roller brush 110; the lower the rotational speed of the main fan, the lower the rotational speed of the roller brush 110. Similarly, when the rotational speed of the roller brush 110 is positively correlated with the rotational speed of the base station fan, the higher the rotational speed of the base station fan, the higher the rotational speed of the roller brush 110; the lower the rotational speed of the base station fan, the lower the rotational speed of the roller brush 110.

[0079] It is understandable that the rotation speed of the roller brush 110 is positively correlated with the rotation speed of the host fan or base station fan. When the roller brush 110 rotates too much, causing a lot of dust, paper scraps and lint to be lifted, there can be a sufficiently large airflow to carry away the lifted dust, paper scraps and lint, preventing the lifted dust, paper scraps and lint from being re-adsorbed by the roller brush 110.

[0080] Reference Figure 3 In some embodiments of the cleaning system provided by the present invention, the second outlet 123 is provided with a first baffle that automatically opens under the negative pressure generated when the base station fan is turned on. It should be noted that when the base station fan is not turned on, the first baffle should be in a closed state for the second outlet 123. Related technologies have various structures that can achieve this function, such as using a torsion spring to apply force so that the first baffle is in a closed state for the second outlet 123 when no other external force is applied. When the base station fan is turned on, the airflow generated by the negative pressure overcomes the force applied by the torsion spring, thereby pushing the first baffle to open automatically. The first baffle being in a closed state when the base station fan is not turned on can prevent the leakage of dust and debris collected inside the dust box 120.

[0081] Continue to refer to Figure 3In the cleaning system provided in some embodiments of the present invention, the other end of the dust collection duct 130 is disposed on the side of the cleaning robot 100, and is provided with a second baffle 131 that can be automatically opened under the negative pressure generated when the base station fan is turned on.

[0082] Understandably, the other end of the dust collection duct 130 can also be located on the upper surface of the cleaning robot 100. It should be noted that when the base station fan is not turned on, the second baffle 131 should be in the closed state of the other end of the dust collection duct 130. The other end of the dust collection duct 130 serves as the port for connecting with the dust collection port 210 of the base station 200. When the cleaning robot 100 moves to the outside to clean the ground, it is blocked and closed by the second baffle 131, which has a better aesthetic effect.

[0083] Reference Figure 3 and Figure 5 In the cleaning system provided in some embodiments of the present invention, the cleaning robot 100 is provided with a chamber 140 for placing a dust box 120, and a roller brush 110 is installed on the side of the chamber 140 facing the forward direction of the cleaning robot 100. The side of the chamber 140 is provided with a first pair of interfaces 141 corresponding to the dust box suction port 121.

[0084] In this embodiment, the dust box 120 is placed in the upper chamber 140 of the cleaning robot 100. Therefore, the user can manually remove the dust box 120 from the chamber 140 for cleaning when needed, which improves the flexibility of use. The roller brush 110 is installed on the side of the chamber 140 facing the forward direction of the cleaning robot 100. Therefore, when the cleaning robot 100 moves forward to sweep the ground, the roller brush 110 first sweeps and stirs up the dust on the ground, and then the airflow generated by the main fan carries the dust from the first pair of interfaces 141 into the dust box 120, thereby achieving a better dust suction effect.

[0085] Reference Figure 3 and Figure 5 In the cleaning system provided in some embodiments of the present invention, the main fan is installed on the side of the chamber 140 facing the backward direction of the cleaning robot 100, and the side of the chamber 140 is also provided with a second pair of interfaces 142 corresponding to the first outlet 122.

[0086] In this embodiment, after the airflow carrying dust enters the dust box 120, it flows from the first outlet 122 of the dust box 120 through the second pair of interfaces 142 of the chamber 140 to the main fan, and finally is discharged to the outside of the cleaning robot 100 through the air outlet 180 of the main fan.

[0087] Reference Figure 3 and Figure 6In the cleaning system provided in some embodiments of the present invention, the cleaning robot 100 is further provided with two rotating mops 150 at the rear, and the air outlet 180 of the main fan faces the rear of the two rotating mops 150.

[0088] Understandably, after the two rotating mops 150 have mopped the floor, the floor will be quite damp. The air outlet 180 of the main unit's fan faces the rear of the two rotating mops 150, which can blow air onto the damp floor after mopping, which helps the floor dry quickly.

[0089] Reference Figures 2 to 4 In the cleaning system provided in some embodiments of the present invention, the rear side of the cleaning robot 100 is provided with a charging terminal 160 and a sensing module 170 for docking with the base station 200.

[0090] In this embodiment, when the cleaning robot 100 returns to the base station 200 and docks, the charging terminal 160 on the rear side of the cleaning robot 100 will connect with the corresponding power supply terminal 220 on the base station 200, thereby enabling the cleaning robot 100 to be charged and recharged. It can be understood that the rear side of the cleaning robot 100 is provided with two charging terminals 160, corresponding to the positive and negative terminals respectively. Correspondingly, the base station 200 is also provided with two power supply terminals 220, corresponding to the positive and negative terminals respectively. In addition, the rear side of the cleaning robot 100 is also provided with a sensing module 170, and the base station 200 is correspondingly provided with a base station sensing module 230. When the base station sensing module 230 senses the sensing module 170 of the cleaning robot 100, it indicates that the cleaning robot 100 has docked, thereby triggering the base station 200 to perform charging and dust collection operations on the cleaning robot 100.

[0091] It will be understood by those skilled in the art that all or some of the steps and systems in the methods disclosed above can be implemented as software, firmware, hardware, and suitable combinations thereof. Some or all of the physical components can be implemented as software executed by a processor, such as a central processing unit, digital signal processor, or microprocessor, or as hardware, or as an integrated circuit, such as an application-specific integrated circuit.
