Detailed description of the embodiments

[0035] The embodiments of the present disclosure will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present disclosure and should not be construed as limiting the present disclosure.

[0036] Reference will be made below to Figures 1 - 5 Describe the cleaning system 100 according to the embodiments of the present disclosure.

[0037] Please refer to Figures 1 - 3 , Figure 1 Schematic structural diagram of the cleaning system according to an embodiment of the present disclosure; Figure 2 is Figure 1 Schematic structural diagram of the cleaning base station of the cleaning system shown in Figure 3 isFigure 1 Simplified structural diagram of the cleaning system shown. The cleaning system 100 according to an embodiment of the present disclosure includes a cleaning base station 20, the cleaning base station 20 includes a first air duct 201, a dust collection assembly 21 and a first fan 22, the dust collection assembly 21 is arranged in the first air duct 201, and the first end (for example, the air outlet) of the first air duct 201 is communicated with the air inlet of the first fan 22. When the first fan 22 operates, dust, garbage and other wastes can enter the dust collection assembly 21 through the first air duct 201 under the action of negative pressure, so that dust, garbage and other wastes can be collected into the dust collection assembly 21.

[0038] The cleaning system 100 further includes a cleaning device 30, the cleaning device 30 includes a dust box 31 and a dirt suction channel, the dust box 31 has an inlet, a first air outlet 311, a second air outlet 312 and a filter element 32, the inlet is communicated with the dirt suction channel, and the filter element 32 is arranged at the second air outlet 312. When the cleaning device 30 operates, the air with dust, garbage and other wastes can enter the dust box 31 from the inlet through the dirt suction channel under the action of negative pressure. Under the filtering action of the filter element 32, dust, garbage and other wastes can be left in the dust box 31, and the relatively clean air can flow out from the second air outlet 312.

[0039] Wherein, the cleaning base station 20 further includes an air passing channel 202, the first end (for example, the air inlet) of the air passing channel 202 is communicated with the air outlet of the first fan 22. When the cleaning device 30 moves to the docking position of the cleaning base station 20 and performs a dust collection operation and is in the first dust collection mode, the first air outlet 311 of the dust box 31 is communicated with the second end (for example, the air inlet) of the first air duct 201, and the second air outlet 312 is communicated with the second end (for example, the air outlet) of the air passing channel 202, so as to clean the filter element 32 through the air flow formed when the first fan 22 operates.

[0040] That is to say, when the cleaning device 30 moves to the docking position of the cleaning base station 20, the cleaning device 30 is docked with the cleaning base station 20 and starts to perform a dust collection operation. When the cleaning base station 20 is in the first dust collection mode and the first fan 22 of the cleaning base station 20 operates, the dust, garbage and other wastes in the dust box 31 of the cleaning device 30 can enter the dust collection assembly 21 through the first air duct 201 under the action of negative pressure, and the dust, garbage and other wastes are collected into the dust collection assembly 21, while the relatively clean air is discharged from the air outlet of the first fan 22 and enters the air passing channel 202. The air flow in the air passing channel 202 can enter the dust box 31 of the cleaning device 30 from the second air outlet 312, and then enter the first air duct 201 again, so as to form an air flow cycle and achieve a dust collection effect.

[0041] During the process that the airflow in the air passage 202 enters the dust box 31 from the second air outlet 312, the airflow can impact the filter element 32 at the second air outlet 312, so as to blow the dust and other garbage attached to the filter element 32 into the dust box 31, realizing the cleaning of the filter element 32. The dust blown off from the filter element 32 can finally follow the airflow and be collected into the dust collection assembly 21 together with the garbage in the dust box 31.

[0042] According to the cleaning system 100 of the present disclosure embodiment, by providing the air passage 202, when the cleaning device 30 is docked with the cleaning base station 20, the second air outlet 312 of the dust box 31 of the cleaning device 30 and the air outlet of the first air duct 201 of the cleaning base station 20 can be communicated through the air passage 202. During the execution of the first dust collection mode, the airflow discharged from the first air duct 201 can be introduced to the second air outlet 312 of the dust box 31 through the air passage 202, so as to clean the filter element 32 at the second air outlet 312, extend the service life of the filter element 32. On the one hand, the self-cleaning of the filter element 32 can be realized, which can reduce the number of times for the user to manually clean or replace the filter element 32, and is beneficial to improving the user experience. On the other hand, it can avoid the cleaning power of the cleaning device 30 from decreasing due to the blockage of the filter element 32, and ensure the cleaning effect and cleaning efficiency of the cleaning device 30.

[0043] Wherein, in the first dust collection mode, the first fan 22 can be controlled to work at a fixed power; or the first fan 22 can be first controlled to work at a high power and then controlled to work at a low power, so as to reduce the noise as much as possible when cleaning the filter element 32.

[0044] Please refer to Figure 4 , Figure 4 FIG. is a simplified structural diagram of the cleaning system 100 according to another embodiment of the present disclosure. The cleaning base station 20 further includes a first exhaust air passage 203. When in the second dust collection mode, the first air outlet 311 is communicated with the second end (for example, the air inlet) of the first air duct 201, the first end (for example, the air inlet) of the first exhaust air passage 203 is communicated with the air outlet of the first fan 22, and the second end (for example, the air outlet) of the first exhaust air passage 203 is communicated with the outside.

[0045] When the cleaning base station 20 is in the second dust collection mode, the first fan 22 of the cleaning base station 20 works. The dust, garbage and other garbage in the dust box 31 of the cleaning device 30 can enter the dust collection assembly 21 through the first air duct 201 under the negative pressure, and the dust, garbage and other garbage are collected into the dust collection assembly 21. The relatively clean air is discharged from the air outlet of the first fan 22 and enters the first exhaust air passage 203, and finally is discharged to the outside through the first exhaust air passage 203.

[0046] In the above technical solution, by providing the first exhaust passage 203, the first exhaust passage 203 can be used to connect the air outlet of the first fan 22 and the outside. When the cleaning base station 20 is in the second dust collection mode, the air flow entering the dust collection assembly 21 can be exhausted to the outside through the first exhaust passage 203 after being filtered, achieving the air pressure balance inside and outside the dust collection assembly 21 and ensuring that the dust collection assembly 21 can collect dust normally.

[0047] Please refer to again Figure 4 , in some embodiments, the cleaning base station 20 further includes a switching component 23, and the switching component 23 is configured to selectively connect the air outlet of the first fan 22 to the air passing passage 202 or the first exhaust passage 203. Among them, the switching component 23 can be an electromagnetic switching valve or two on-off valves.

[0048] Specifically, when the switching component 23 switches to the state where the air outlet of the first fan 22 is connected to the air passing passage 202, the cleaning base station 20 can execute the first dust collection mode. When the switching component 23 switches to the state where the air outlet of the first fan 22 is connected to the first exhaust passage 203, the cleaning base station 20 can execute the second dust collection mode. Therefore, by providing the switching component 23, the switching between the first dust collection mode and the second dust collection mode can be achieved.

[0049] For ease of understanding, the following describes an embodiment in which the cleaning base station 20 includes an air passing passage 202 and a first exhaust passage 203. In this embodiment, the cleaning base station 20 can have a first dust collection mode and a second dust collection mode.

[0050] Specifically, in the first dust collection mode, the air inlet of the air passage 202 is connected to the air outlet of the first fan 22, the first air inlet 311 of the dust box 31 is connected to the air inlet of the first air duct 201, the second air inlet 312 of the dust box 31 is connected to the air outlet of the air passage 202, the first fan 22 of the cleaning base station 20 can operate at a fixed power, or the first fan 22 of the cleaning base station 20 can first operate at a first operating power (denoted as P1) and then operate at a second operating power (denoted as P2, where P2 can be less than P1). Dust, garbage, etc. in the dust box 31 of the cleaning device 30 can enter the dust collection assembly 21 through the first air duct 201 under the action of negative pressure, and the dust, garbage, etc. are collected into the dust collection assembly 21, while the relatively clean air is discharged from the air outlet of the first fan 22 and enters the air passage 202. The air flow in the air passage 202 can enter the dust box 31 of the cleaning device 30 from the second air inlet 312, and then enter the first air duct 201 again, thus forming an air flow cycle to achieve the dust collection effect. At the same time, the air flow in the air passage 202 enters the dust box 31 from the second air inlet 312, which can impact the filter element 32 at the second air inlet 312, and the dust and other garbage attached to the filter element 32 are blown into the dust box 31, realizing the cleaning of the filter element 32.

[0051] In the second dust collection mode, the first air inlet 311 is connected to the air inlet of the first air duct 201, one end of the first exhaust air passage 203 is connected to the air outlet of the first fan 22 and the other end is connected to the outside. The first fan 22 of the cleaning base station 20 can operate at a third operating power (denoted as P3, where P3 can be less than P1). Dust, garbage, etc. in the dust box 31 of the cleaning device 30 can enter the dust collection assembly 21 through the first air duct 201 under the action of negative pressure, and the dust, garbage, etc. are collected into the dust collection assembly 21, while the relatively clean air is discharged from the air outlet of the first fan 22 and enters the first exhaust air passage 203, and finally is discharged to the outside through the first exhaust air passage 203.

[0052] That is to say, when the cleaning base station 20 executes the first dust collection mode, in addition to collecting the garbage in the dust box 31 into the dust collection assembly 21, it can also clean the filter element 32 at the second air inlet 312 of the dust box 31; when the cleaning base station 20 executes the second dust collection mode, it can collect the garbage in the dust box 31 into the dust collection assembly 21.

[0053] When the cleaning device 30 moves to the docking position of the cleaning base station 20, the user can select a dust collection mode as needed. For example, the user can control the cleaning base station 20 to separately execute the first dust collection mode, so that the garbage in the dust box 31 can be collected into the dust collection assembly 21, and the filter element 32 at the second air outlet 312 of the dust box 31 can be cleaned; for another example, the user can control the cleaning base station 20 to separately execute the second dust collection mode, so that the garbage in the dust box 31 can be collected into the dust collection assembly 21; for still another example, the user can control the cleaning base station 20 to first execute the first dust collection mode and then execute the second dust collection mode, or control the cleaning base station 20 to first execute the second dust collection mode and then execute the first dust collection mode.

[0054] Please refer to again Figure 3 and Figure 4 According to some embodiments of the present disclosure, a heating element 24 is provided in the air passage 202, and the heating element 24 is used to heat the air flow in the air passage 202, and the heating element 24 operates for a preset duration in the first dust collection mode.

[0055] The heating element 24 can heat the air flow in the air passage 202, so as to increase the air flow temperature. The air flow with a higher temperature enters the dust box 31 and the dust collection assembly 21, which can not only dry the filter element 32 and the interior of the dust box 31, but also dry the dust, garbage, etc. in the dust collection assembly 21, avoiding the interior of the dust box 31 and the dust collection assembly 21 from emitting an odor.

[0056] In addition, since it takes a long time for the heating element 24 to completely dry the interior of the dust box 31, the first fan 22 also works for a long time synchronously with the heating element 24, and it is inevitable that a certain amount of noise is generated when the first fan 22 works; in the above technical solution, by controlling the working duration of the heating element 24, the working duration of the first fan 22 can be indirectly controlled, avoiding the first fan 22 from affecting the user due to too long working time.

[0057] Please refer to again Figure 1 According to some embodiments of the present disclosure, the interior of the cleaning device 30 has a second air duct 302, and the housing of the cleaning device 30 has a ventilation part 3021. The second air duct 302 communicates with the second air outlet 312 of the dust box 31 and the ventilation part 3021.

[0058] When the cleaning device 30 works, the air with dust, garbage, etc. can enter the dust box 31 from the inlet through the dirt suction channel under the negative pressure. Under the filtering action of the filter element 32, the dust, garbage, etc. can stay in the dust box 31, and the relatively clean air can flow out of the dust box 31 from the second air outlet 312, enter the second air duct 302, and finally be discharged to the outside from the ventilation part 3021.

[0059] Further, in a state where the cleaning device 30 moves to the docking position of the cleaning base station 20 and is in the first dust collection mode, the air outlet of the air passage 202 is disposed opposite to and communicated with the ventilation part 3021, so that the air outlet of the air passage 202 is communicated with the second air outlet 312, that is, the air outlet of the air passage 202 and the second air outlet 312 of the dust box 31 are communicated through the second air duct 302.

[0060] When the first fan 22 of the cleaning base station 20 works, dust, garbage, etc. in the dust box 31 of the cleaning device 30 can enter the dust collection assembly 21 through the first air duct 201 under the action of negative pressure, and the dust, garbage, etc. are collected into the dust collection assembly 21, while the relatively clean air is discharged from the air outlet of the first fan 22, flows through the air passage 202 and the second air duct 302 in sequence, and then enters the dust box 31 from the second air outlet 312, and the dust, garbage, etc. attached to the filter element 32 are blown into the dust box 31, so as to realize the cleaning of the filter element 32.

[0061] In the above technical solution, by arranging the second air duct 302 inside the cleaning device 30, the second air duct 302 can be reasonably arranged according to the relative position between the second air outlet 312 of the dust box 31 and the ventilation part 3021, so that the ventilation part 3021 is communicated with the second air outlet 312 of the dust box 31, so that when the cleaning device 30 moves to the docking position of the cleaning base station 20, the air outlet of the air passage 202 can be communicated with the second air outlet 312 of the dust box 31.

[0062] Please refer to again Figure 1 , in some embodiments, the ventilation part 3021 includes a plurality of ventilation holes 3022, and the plurality of ventilation holes 3022 are arranged at intervals on the peripheral wall of the housing of the cleaning device 30.

[0063] Thus, by arranging the ventilation part 3021 to include a plurality of ventilation holes 3022, on the one hand, foreign objects with larger volume can be prevented from entering the internal air duct of the cleaning device 30 through the ventilation part 3021, ensuring the smoothness of the air duct, and fingers can also be prevented from reaching into the internal air duct, reducing potential safety hazards. On the other hand, the plurality of ventilation holes 3022 can disperse the air flow, avoiding discomfort caused by direct blowing.

[0064] In some embodiments, a sealing ring (not shown in the figure) is provided between the peripheral wall of the housing of the cleaning device 30 and the wall body where the air outlet of the air passage 202 of the cleaning base station 20 is located, and the sealing ring surrounds the second end (for example, the air outlet) of the air passage 202 and the periphery of the ventilation holes 3022.

[0065] Among them, the sealing ring can be installed on the peripheral wall of the housing of the cleaning device 30 or on the wall body where the air outlet of the air passing channel 202 is located. For example, an annular groove is provided on the outer surface of the peripheral wall of the housing of the cleaning device 30, and the annular groove surrounds the outer periphery of the ventilation part 3021, that is, the annular groove surrounds the outside of the plurality of ventilation holes 3022; alternatively, an annular groove is provided on the wall body where the air outlet of the air passing channel 202 is located, and the annular groove surrounds the outside of the air outlet of the air passing channel 202, and the annular groove is used for installing the sealing ring.

[0066] In the above technical solution, by providing the sealing ring, it is ensured that the peripheral wall of the cleaning device 30 and the wall body where the air outlet of the air passing channel 202 is located can be hermetically fitted, thereby avoiding air leakage and being beneficial to ensuring the cleaning effect on the filter element 32.

[0067] In some embodiments, the air outlet of the air passing channel 202 is an arc-shaped hole extending along the circumferential direction of the housing of the cleaning device 30. In the state where the cleaning device 30 moves to the docking position of the cleaning base station 20, the hole edge of the air outlet of the air passing channel 202 can be matched with the peripheral wall where the ventilation part 3021 of the cleaning device 30 is located, so as to ensure the sealing performance of the cooperation between the hole edge of the air outlet of the air passing channel 202 and the peripheral wall of the cleaning device 30, avoid air leakage, and be beneficial to ensuring the cleaning effect on the filter element 32. Moreover, by setting the air outlet of the air passing channel 202 as an arc-shaped hole, the air volume passing through the air passing channel 202 per unit time can also be increased, so that more airflows impact the filter element 32 at the second air outlet 312, thereby being beneficial to improving the cleaning effect on the filter element 32.

[0068] In some embodiments not shown in the figure, the interior of the cleaning device 30 has a second exhaust air channel, the housing of the cleaning device 30 has an exhaust part, and the second air outlet 312 and the exhaust part are communicated through the second exhaust air channel.

[0069] Among them, the cleaning device 30 further includes a second fan 33. When the second fan 33 operates, the airflow formed drives the garbage on the surface to be cleaned to enter the dust box 31 from the inlet through the dirt suction channel, and the airflow is discharged from the exhaust part after being filtered by the filter element 32.

[0070] Specifically, when the second fan 33 operates, a negative pressure area can be formed at a local position upstream of the dirt suction channel. The air with dust, garbage, etc. can enter the dust box 31 from the inlet through the dirt suction channel under the action of the negative pressure. Under the filtering action of the filter element 32, the dust, garbage, etc. can stay in the dust box 31, and the relatively clean air can flow out of the dust box 31 from the second air outlet 312 and enter the second exhaust air channel, and finally be discharged to the outside from the exhaust part.

[0071] In the above technical solution, by providing a second exhaust passage inside the cleaning device 30, the second exhaust passage can be reasonably arranged according to the relative positions of the second air outlet 312 of the dust box 31 and the exhaust part, so that the exhaust part communicates with the second air outlet 312 of the dust box 31. Thus, when the cleaning device 30 moves to the docking position of the cleaning base station 20, the air outlet of the air passage 202 can communicate with the second air outlet 312 of the dust box 31.

[0072] In some examples, the second exhaust passage is provided independently of the second air duct 302, and the exhaust part and the ventilation part 3021 have different structures. That is to say, the second exhaust passage and the exhaust part exhaust air when the cleaning device 30 performs a cleaning task, and the second air duct 302 and the ventilation part 3021 intake air when the cleaning device 30 docks with the cleaning base station 20 to perform a dust collection task.

[0073] With such an arrangement, the second exhaust passage, the second air duct 302, the exhaust part, and the ventilation part 3021 can be designed separately according to the design requirements of exhaust and intake, so as to meet different design requirements.

[0074] Specifically, when the cleaning device 30 performs a cleaning task, the second fan 33 operates, and the air with dust, garbage, etc. can enter the dust box 31 from the inlet through the sewage suction passage under the action of negative pressure. Under the filtering action of the filter element 32, the dust, garbage, etc. can be retained in the dust box 31, and the relatively clean air can flow out of the dust box 31 from the second air outlet 312 and enter the second exhaust passage, and finally be discharged to the outside from the exhaust part.

[0075] When the cleaning device 30 moves to the docking position of the cleaning base station 20 and the dust collection operation is started, it is in the first dust collection mode. The first fan 22 operates, and the dust, garbage, etc. in the dust box 31 of the cleaning device 30 can enter the dust collection assembly 21 through the first air duct 201 under the action of negative pressure, and the dust, garbage, etc. are collected into the dust collection assembly 21. The relatively clean air is discharged from the air outlet of the first fan 22, then flows through the air passage 202, enters the second air duct 302 from the ventilation part 3021, and then enters the dust box 31 from the second air outlet 312, blowing the dust and other garbage attached to the filter element 32 into the dust box 31 to clean the filter element 32.

[0076] In other examples, the second exhaust passage and the second air duct 302 are the same passage, and the exhaust part and the ventilation part 3021 are the same structure. That is to say, the second air duct 302 and the ventilation part 3021 can both exhaust air when the cleaning device 30 performs a cleaning task and intake air when the cleaning device 30 docks with the cleaning base station 20 to perform a dust collection task.

[0077] Such a setting can reduce the occupied space of the internal air duct of the cleaning device 30, simplify the structure of the internal air duct of the cleaning device 30, and is conducive to reducing the processing difficulty.

[0078] Please refer to again Figure 1 and further refer to Figure 5 , Figure 5 is a structural block diagram of a cleaning device according to an embodiment of the present disclosure. The second exhaust passage and the second air duct 302 are the same passage. The cleaning system 100 further includes a reverse rotation prevention control module 36. When in the first dust collection mode, the reverse rotation prevention control module 36 is used to control the circuit where the motor of the second fan 33 is located to be open or the positive and negative poles of the motor of the second fan 33 to be short-circuited.

[0079] Specifically, when the cleaning device 30 performs a cleaning task, the second fan 33 operates. Air with dust, garbage, etc. can enter the dust box 31 from the inlet through the dirt suction passage under the action of negative pressure. Under the filtering action of the filter element 32, dust, garbage, etc. can be left in the dust box 31, and relatively clean air can flow out of the dust box 31 from the second air outlet 312 and enter the second air duct 302, and finally be discharged to the outside from the ventilation part 3021.

[0080] When the cleaning device 30 moves to the docking position of the cleaning base station 20 and the dust collection operation is started, it is in the first dust collection mode. The first fan 22 operates. Dust, garbage, etc. in the dust box 31 of the cleaning device 30 can enter the dust collection assembly 21 through the first air duct 201 under the action of negative pressure, and the dust, garbage, etc. are collected into the dust collection assembly 21, while relatively clean air is discharged from the air outlet of the first fan 22, then flows through the air passage 202, enters the second air duct 302 from the ventilation part 3021, and then enters the dust box 31 from the second air outlet 312, blowing the dust and other garbage attached to the filter element 32 into the dust box 31 to realize the cleaning of the filter element 32.

[0081] In the aforementioned first dust collection mode, when the second fan 33 rotates under the drive of the reverse air flow, the motor of the second fan 33 can be converted into a generator. If the reverse rotation prevention control module 36 can control the circuit where the motor of the second fan 33 is located to be open, since the circuit cannot form a loop, current can be prevented from being generated to burn out the motor main board, and the second fan 33 can also be stopped from rotating, reducing the working noise.

[0082] In the aforementioned first dust collection mode, when the second fan 33 rotates under the drive of the reverse airflow, the motor of the second fan 33 can be converted into a generator. If the anti-reverse control module 36 can control the positive and negative poles of the motor of the second fan 33 to be short-circuited or the circuit where the motor is located is broken, due to Lenz's law, a braking force opposite to the movement of the rotor is generated, so that the rotor can be self-locked, thereby preventing the current from burning the motor main board, and can also stop the second fan 33 from rotating, thereby reducing working noise.

[0083] In other examples, the second fan 33 is a centrifugal fan, that is, the impeller of the second fan 33 is a centrifugal impeller. When the air flow enters the second air duct 302 from the ventilation portion 3021, the centrifugal impeller hardly rotates, or swings slightly, that is, the second fan 33 will achieve self-locking and reduce working noise.

[0084] Please refer again Figure 1 and Figure 5 In some embodiments, the cleaning device 30 further includes a driving wheel 34 and an anti-reverse thrust control module 35 , and the anti-reverse thrust control module 35 is used to control the positive and negative poles of the driving motor of the driving wheel 34 to be short-circuited.

[0085] When the driving wheel 34 drives the cleaning device 30 to move to the parking position of the cleaning base station 20, the cleaning device 30 is docked with the cleaning base station 20, so that the wall where the air outlet of the air passage 202 is located is sealed with the peripheral wall of the cleaning device 30. By setting an anti-reverse thrust control module 35, the positive and negative poles of the driving motor of the driving wheel 34 are short-circuited by the anti-reverse thrust control module 35. Due to Lenz's law, a braking force opposite to the movement of the rotor is generated, so that the rotor can be self-locked and the driving wheel 34 stops rotating, thereby preventing the airflow discharged from the air outlet of the air passage 202 from blowing the cleaning device 30 and causing the cleaning device 30 to shift.

[0086] Please refer again Figure 1 and Figure 2 In some embodiments, the cleaning base station 20 further includes a limit member 25, which is located below, above or around the cleaning device 30. The limit member 25 is movable between a first position and a second position. In the first position, the limit member 25 avoids the cleaning device 30 to allow the cleaning device 30 to move. In the second position, the limit member 25 forms a stop for the cleaning device 30 to keep the cleaning device 30 in a docked position.

[0087] The limiting member 25 can rotate between the first position and the second position under the drive of the power component, or the limiting member 25 can move between the first position and the second position under the drive of the power component. The power component can be a motor, a solenoid valve or other structures.

[0088] In an embodiment where the limiting member 25 is located below the cleaning device 30, the limiting member 25 can be used to block structures such as the drive wheels 34, omnidirectional wheels, or cleaning assemblies of the cleaning device 30; in an embodiment where the limiting member 25 is located above the cleaning device 30, the limiting member 25 can be used to block structures such as the radar of the cleaning device 30; in an embodiment where the limiting member 25 is located on the peripheral side of the cleaning device 30, the limiting member 25 can be used to block the peripheral wall of the cleaning device 30 or structures on the peripheral wall, etc.

[0089] In the above technical solution, by providing the movable limiting member 25, when the cleaning device 30 moves to the docking position of the cleaning base station 20, the limiting member 25 can be moved to the second position, and the limiting member 25 can be used to block part of the structure of the cleaning device 30, so as to avoid the airflow discharged from the air outlet of the air passage 202 blowing the cleaning device 30 and causing the cleaning device 30 to shift; when the cleaning device 30 needs to perform a cleaning task, the limiting member 25 can be moved to the first position, so that the limiting member 25 avoids the cleaning device 30, and thus the cleaning device 30 can be moved out of the cleaning base station 20.

[0090] The following will describe the control method of the cleaning system 100 according to an embodiment of the present disclosure in conjunction with the attached Figures 1 - 7 The cleaning system 100 is the cleaning system 100 described in any of the above embodiments.

[0091] Please refer to Figure 6 , the control method of the cleaning system 100 according to an embodiment of the present disclosure includes the following steps:

[0092] S1. Control the cleaning device to move to the docking position of the cleaning base station;

[0093] S2. Control the cleaning base station to perform a dust collection operation on the cleaning device, and the dust collection operation includes: a first dust collection mode and / or a second dust collection mode;

[0094] Wherein, the cleaning base station 20 further includes a first exhaust air passage 203. When in the second dust collection mode, the first air outlet 311 is communicated with the air inlet of the first air passage 201, one end of the first exhaust air passage 203 is communicated with the air outlet of the first fan 22 and the other end is communicated with the outside;

[0095] S3. Control the cleaning base station to end the dust collection operation.

[0096] Specifically, please refer to Figure 1 and Figure 4, the cleaning base station 20 includes a first air duct 201, an air passing channel 202, a first exhaust air duct 203, a dust collection assembly 21, and a first fan 22. The dust collection assembly 21 is disposed in the first air duct 201. The air outlet of the first air duct 201 is communicated with the air inlet of the first fan 22. One of the air inlet of the air passing channel 202 and the first end of the first exhaust air duct 203 is communicated with the air outlet of the first fan 22. The second end of the first exhaust air duct 203 is communicated with the outside. The cleaning base station 20 further defines a receiving cavity 204, and the receiving cavity 204 has a side opening 205.

[0097] The cleaning device 30 includes a dust box 31 and a dirt suction channel. The dust box 31 has an inlet, a first air port 311, and a second air port 312. The inlet is communicated with the dirt suction channel, and a filter element 32 is provided at the second air port 312. When the cleaning device 30 moves to the stop and start position of the cleaning base station 20, the cleaning device 30 is located in the receiving cavity 204. The first air port 311 of the dust box 31 is communicated with the air inlet of the first air duct 201, and the second air port 312 of the dust box 31 is communicated with the air outlet of the air passing channel 202.

[0098] In the first dust collection mode, the air inlet of the air passing channel 202 is communicated with the air outlet of the first fan 22. The first air port 311 of the dust box 31 is communicated with the air inlet of the first air duct 201. The second air port 312 of the dust box 31 is communicated with the air outlet of the air passing channel 202. The first fan 22 of the cleaning base station 20 can work at a fixed power, or the first fan 22 of the cleaning base station 20 can first work at a first operating power (denoted as P1), and then work at a second operating power (denoted as P2, P2 can be less than P1). Dust, garbage, etc. in the dust box 31 of the cleaning device 30 can enter the dust collection assembly 21 through the first air duct 201 under the action of negative pressure, and the dust, garbage, etc. are collected into the dust collection assembly 21. The relatively clean air is discharged from the air outlet of the first fan 22 and enters the air passing channel 202. The air flow in the air passing channel 202 can enter the dust box 31 of the cleaning device 30 from the second air port 312, and then enter the first air duct 201 again. In this way, an air flow cycle is formed to achieve the dust collection effect. At the same time, the air flow in the air passing channel 202 enters the dust box 31 from the second air port 312, which can impact the filter element 32 at the second air port 312, and the dust, garbage, etc. attached to the filter element 32 are blown into the dust box 31, realizing the cleaning of the filter element 32.

[0099] In the second dust collection mode, the first air inlet 311 is communicated with the air inlet of the first air duct 201. One end of the first exhaust air passage 203 is communicated with the air outlet of the first fan 22 and the other end is communicated with the outside. The first fan 22 of the cleaning base station 20 can operate at a third operating power (denoted as P3, and P3 can be less than P1). Dust, garbage, etc. in the dust box 31 of the cleaning device 30 can enter the dust collection assembly 21 through the first air duct 201 under the action of negative pressure, and the dust, garbage, etc. are collected into the dust collection assembly 21, while the relatively clean air is discharged from the air outlet of the first fan 22 and enters the first exhaust air passage 203, and finally is discharged to the outside through the first exhaust air passage 203.

[0100] That is to say, when the cleaning base station 20 executes the first dust collection mode, in addition to collecting the garbage in the dust box 31 into the dust collection assembly 21, it can also clean the filter element 32 at the second air inlet 312 of the dust box 31; when the cleaning base station 20 executes the second dust collection mode, it can collect the garbage in the dust box 31 into the dust collection assembly 21.

[0101] When the cleaning device 30 moves to the docking position of the cleaning base station 20 and the dust collection operation is started, the user can select the dust collection mode according to needs.

[0102] For example, the user can control the cleaning base station 20 to execute the first dust collection mode alone, so that the garbage in the dust box 31 can be collected into the dust collection assembly 21, and the filter element 32 at the second air inlet 312 of the dust box 31 can be cleaned, and finally control the cleaning base station 20 to end the first dust collection mode.

[0103] For another example, the user can control the cleaning base station 20 to execute the second dust collection mode alone, so that the garbage in the dust box 31 can be collected into the dust collection assembly 21, and finally control the cleaning base station 20 to end the second dust collection mode.

[0104] For yet another example, the user can control the cleaning base station 20 to first execute the first dust collection mode and then execute the second dust collection mode, and finally control the cleaning base station 20 to end the second dust collection mode; or, control the cleaning base station 20 to first execute the second dust collection mode and then execute the first dust collection mode, and finally control the cleaning base station 20 to end the first dust collection mode.

[0105] Therefore, according to the control method of the cleaning system 100 according to the embodiments of the present disclosure, when the cleaning base station 20 is controlled to operate in the first dust collection mode, the air flow discharged from the first air duct 201 can be introduced to the second air inlet 312 of the dust box 31 through the air passing channel 202, so that the filter element 32 at the second air inlet 312 can be cleaned, realizing self-cleaning of the filter element 32, reducing the number of times the user manually cleans or replaces the filter element 32, being beneficial to improving the user experience, and also avoiding the cleaning power of the cleaning device 30 from decreasing due to blockage of the filter element 32, ensuring the cleaning effect and cleaning efficiency of the cleaning device 30.

[0106] Please refer to Figure 7 , according to some embodiments of the present disclosure, controlling the cleaning base station to turn on the first dust collection mode for the cleaning device includes:

[0107] S21. Control the first fan to operate at the first operating power for the first duration;

[0108] S22. Control the first fan to operate at the second operating power and control the heating element in the air passing channel to be turned on and execute the second duration, where the second operating power is less than the first operating power and / or the second duration is greater than the first duration.

[0109] Since the first fan 22 inevitably generates noise during operation, and the noise generated when the first fan 22 operates at high power is greater than the noise generated when it operates at low power.

[0110] In order to minimize the noise generated by the first fan 22 during the entire operation process as much as possible, in the embodiments of the present disclosure, in the first dust collection mode, first control the first fan 22 to operate at the first operating power (high power) for a short time, which is beneficial to quickly collecting the garbage in the dust box 31 into the dust collection assembly 21 within a short time, that is, minimizing the time for the first fan 22 to operate at high power as much as possible, so as to reduce the time when the user is disturbed by high noise; then control the first fan 22 to operate at the second operating power (low power) for a long time, which can improve the cleaning effect on the filter element 32 on the basis of ensuring that the user is not disturbed by high noise.

[0111] Among them, the second duration is greater than the first duration. The first duration can be 10 seconds, 20 seconds, 30 seconds, etc., and the second duration can be 1 hour, 1.5 hours, 2 hours, etc.

[0112] When the first blower 22 operates at the second operating power, the heating element 24 is controlled to operate. The heating element 24 can heat the air flow in the air passage 202, thereby increasing the air flow temperature. The air flow with a higher temperature enters the dust box 31 and the dust collection assembly 21, which can not only dry the filter element 32 and the interior of the dust box 31, but also dry the dust, garbage, etc. in the dust collection assembly 21, preventing the interior of the dust box 31 and the dust collection assembly 21 from emitting an odor.

[0113] In some embodiments, controlling the cleaning base station 20 to turn on the second dust collection mode for the cleaning device 30 includes: controlling the first blower 22 to operate at a third operating power for a third duration, where the third operating power is less than the first operating power and / or the third duration is less than the first duration.

[0114] It can be understood that when the cleaning base station 20 operates in the first dust collection mode, the air passage 202, the dust box 31, the dust collection assembly 21, and the first blower 22 are in a circulating air duct. When the first blower 22 operates, the air flow generated in the circulating air duct needs to overcome the resistance of the filter element 32 on the dust box 31 and the dust collection assembly 21 to transfer the garbage in the dust box 31 to the dust collection assembly 21. Therefore, when the cleaning base station 20 operates in the first dust collection mode, the first blower 22 needs to operate at a relatively high power (the first operating power P1) to meet the wind force requirements for dust collection.

[0115] When the cleaning base station 20 operates in the second dust collection mode, the air outlet of the first blower 22 is communicated with the first end (e.g., the air inlet) of the first exhaust air passage 203, and the second end (e.g., the air outlet) of the first exhaust air passage 203 is communicated with the outside. When the first blower 22 operates, the internal air flow needs to overcome the resistance of the dust collection assembly 21, but does not need to overcome the resistance of the filter element 32 on the dust box 31 to transfer the garbage in the dust box 31 to the dust collection assembly 21. Therefore, when the cleaning base station 20 operates in the second dust collection mode, compared with the first dust collection mode, the operating power of the first blower 22 can be appropriately reduced, and the first blower 22 can operate at a relatively low power (the third operating power P3) to meet the wind force requirements for dust collection.

[0116] It should be noted that the first end and the second end of the first air duct 201, the first end and the second end of the air passage 202, and the first end and the second end of the first exhaust air passage 203 are not fixedly set as the air outlet or the air inlet, but are defined according to the application scenario requirements. For example, in application scenario A, the first end of the first air duct 201 is the air outlet and the second end is the air inlet; in application scenario B, the first end of the first air duct 201 is the air inlet and the second end is the air outlet. The same explanation applies to the first end and the second end of the air passage 202 and the first end and the second end of the first exhaust air passage 203.

[0117] Please refer to Figure 1 andFigure 5 , according to some embodiments of the present disclosure, the cleaning device 30 further includes a second exhaust passage, an exhaust portion, and a second fan 33. The second air outlet 312 and the exhaust portion are communicated through the second exhaust passage; when the second fan 33 operates, the airflow drives the garbage on the surface to be cleaned to enter the dust box 31 from the inlet through the sewage suction passage, and the airflow is discharged from the exhaust portion after passing through the filter. The control method of the cleaning system 100 further includes:

[0118] During the cleaning process of the filter element 32 by the first fan 22, control the circuit where the motor of the second fan 33 is located to be open-circuited or the positive and negative poles of the motor of the second fan 33 to be short-circuited.

[0119] When the cleaning device 30 moves to the docking position of the cleaning base station 20, when the dust collection operation is started, it is in the first dust collection mode. The first fan 22 operates, and the dust, garbage, etc. in the dust box 31 of the cleaning device 30 can enter the dust collection assembly 21 through the first air duct 201 under the action of negative pressure, and the dust, garbage, etc. are collected into the dust collection assembly 21. The relatively clean air is discharged from the air outlet of the first fan 22, then flows through the air passage 202, enters the second air duct 302 from the ventilation portion 3021, and then enters the dust box 31 from the second air outlet 312, blowing the dust and other garbage attached to the filter element 32 into the dust box 31 to realize the cleaning of the filter element 32.

[0120] In the aforementioned first dust collection mode, when the second fan 33 rotates under the drive of the reverse airflow, the motor of the second fan 33 can be converted into a generator. If the anti-reverse control module 36 can control the circuit where the motor of the second fan 33 is located to be open-circuited, since the circuit cannot form a loop, current can be prevented from being generated to burn out the motor main board, and the second fan 33 can also be stopped from rotating, reducing the working noise.

[0121] In the aforementioned first dust collection mode, when the second fan 33 rotates under the drive of the reverse airflow, the motor of the second fan 33 can be converted into a generator. If the anti-reverse control module 36 can control the positive and negative poles of the motor of the second fan 33 to be short-circuited, due to the Lenz's law, a braking force opposite to the movement of the rotor is generated, so that the rotor can be self-locked. Therefore, current can be prevented from being generated to burn out the motor main board, and the second fan 33 can also be stopped from rotating, reducing the working noise.

[0122] Please refer to Figure 1 and Figure 5 , according to some embodiments of the present disclosure, the control method of the cleaning system 100 further includes:

[0123] After controlling the cleaning device 30 to move to the docking position of the cleaning base station 20, it further includes: controlling the positive and negative poles of the drive motor of the drive wheel 34 of the cleaning device 30 to be short-circuited.

[0124] When the driving wheel 34 drives the cleaning device 30 to move to the parking position of the cleaning base station 20, the cleaning device 30 is docked with the cleaning base station 20, so that the wall where the air outlet of the air passage 202 is located is sealed with the peripheral wall of the cleaning device 30. By setting an anti-reverse thrust control module 35, the positive and negative poles of the driving motor of the driving wheel 34 are short-circuited by the anti-reverse thrust control module 35. Due to Lenz's law, a braking force opposite to the movement of the rotor is generated, so that the rotor can be self-locked and the driving wheel 34 stops rotating, thereby preventing the airflow discharged from the air outlet of the air passage 202 from blowing the cleaning device 30 and causing the cleaning device 30 to shift.

[0125] See also Figure 2 According to some embodiments of the present disclosure, the cleaning base station 20 further includes a movable stopper 25, and the control method of the cleaning system 100 further includes:

[0126] After controlling the cleaning device 30 to move to the parking position of the cleaning base station 20, the method further includes: controlling the limiting member 25 to move toward a position to stop the cleaning device 30, so that the cleaning device 30 remains at the parking position.

[0127] In the above technical solution, by setting a movable limit member 25, when the cleaning device 30 moves to the parking position of the cleaning base station 20, the limit member 25 can be moved to the second position, and the limit member 25 can be used to stop part of the structure of the cleaning device 30, thereby preventing the airflow discharged from the air outlet of the air passage 202 from blowing the cleaning device 30 and causing the cleaning device 30 to shift; when the cleaning device 30 needs to perform a cleaning task, the limit member 25 can be moved to the first position, so that the limit member 25 avoids the cleaning device 30, so that the cleaning device 30 can be moved out of the cleaning base station 20.

[0128] According to the embodiment of the present disclosure, the cleaning system 100 includes a processor and a memory. The memory stores computer program instructions. When the computer program instructions are run by the processor, they are used to execute the control method of any of the above-mentioned embodiments, which can realize self-cleaning of the filter element 32, which is beneficial to improving the user experience and ensuring the cleaning effect and cleaning efficiency of the cleaning device 30.
