[0035] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0036] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. In the description of the present application, the orientations or positional relationships such as "top" and "bottom" are orientations or positional relationships based on normal use. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The descriptions such as "first" and "second" in the embodiments of the present application are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of the present application, the meaning of "multiple" is at least two, that is, including two and more than two, such as two or three, etc., unless otherwise clearly and specifically limited.

[0037] For the first aspect of the embodiment of the present application, please refer to Figures 1 to 4 , provides a dust exhaust control method for a cleaning system, wherein the cleaning system includes a base station 1 and a vacuum cleaner 2, the base station 1 includes a first fan assembly 11, and the vacuum cleaner 2 includes a second fan assembly 21.

[0038] The base station 1 is used to receive the debris discharged by the vacuum cleaner 2. It can be understood that the debris refers to garbage, dust, etc. absorbed by the vacuum cleaner 2.

[0039] Understandably, please refer to Figures 1 to 3 The vacuum cleaner 2 has a dust cup 22, which is used to hold debris.

[0040] For example, the dust collection principle of the vacuum cleaner 2 is as follows: the second fan assembly 21 of the vacuum cleaner 2 is driven at high speed to discharge the air in the impeller of the second fan assembly 21 out of the second fan assembly 21 at high speed, and at the same time, the air in the vacuum cleaner 2 is continuously replenished into the second fan assembly 21. In this way, a higher pressure difference can be formed with the outside world. Debris is sucked into the vacuum cleaner 2 along with the air, and the debris is collected in the dust cup 22.

[0041] That is to say, after the debris is collected in the dust cup 22 , the debris in the dust cup 22 is cleaned by connecting the dust cup 22 with the base station 1 .

[0042] The method in which the base station 1 cleans the debris in the vacuum cleaner 2 is not limited.

[0043] Exemplarily, after the base station 1 is connected to the dust cup 22 of the vacuum cleaner 2, the dust cup 22 is located above the base station 1, and the debris can be discharged into the base station 1 under the action of gravity, so that the base station 1 can collect the debris.

[0044] Exemplarily, the dust collection principle of the base station 1 is as follows: the first fan assembly 11 of the base station 1 is driven at high speed to discharge the air in the impeller of the first fan assembly 11 out of the first fan assembly 11 at high speed, and at the same time, the air in the base station 1 is continuously replenished into the first fan assembly 11. In this way, a higher pressure difference can be formed with the outside world. Because the base station 1 is connected to the vacuum cleaner 2, the debris in the dust cup 22 of the vacuum cleaner 2 is sucked into the base station 1 along with the air, and the debris is collected in the base station 1.

[0045] The dust discharge control method comprises a first dust collection stage, a first reversing suction stage and a convection cleaning stage, wherein the first reversing suction stage is located before the convection cleaning stage and after the first dust collection stage.

[0046] Step S1, the first dust collection stage: confirm that the vacuum cleaner 2 is successfully docked with the base station 1; control the first fan assembly 11 to be in a running state, and control the second fan assembly 21 to be in a closed state.

[0047] Specifically, after confirming that the vacuum cleaner 2 is successfully docked with the base station 1, by controlling the first fan assembly 11 to operate and controlling the second fan assembly 21 to shut down, the base station 1 can be controlled to collect dust from the vacuum cleaner 2, thereby achieving timely and accurate cleaning of debris accumulated in the vacuum cleaner 2.

[0048] Step S2, first reversing suction stage: controlling the first fan assembly 11 to be in a closed state, and controlling the second fan assembly 21 to be in a running state.

[0049] It is understandable that during the initial dust collection stage, the base station can clean up most of the debris in the vacuum cleaner, but inevitably there will be a small amount of debris located in the dead corners of the dust cup or entangled in the dust cup, such as hair, fluff, etc., which are difficult to be cleaned well by the base station during the initial dust collection stage.

[0050] Specifically, in the first reversing suction stage, the second fan assembly 21 disturbs the debris in the dead corners of the dust cup 22 or the debris entangled in the dust cup 22, loosens the debris in the dead corners of the dust cup 22 or the debris entangled in the dust cup 22, and paves the way for cleaning the debris in the subsequent convection cleaning stage.

[0051] It should be noted that in the first reversing suction stage, the vacuum cleaner 2 is connected to the base station 1, and the first fan assembly 11 is in a closed state. The base station 1 will not suck the vacuum cleaner 2. By controlling the second fan assembly 21 to be in an operating state, the airflow in the vacuum cleaner 2 can produce a directional flow, thereby disturbing the debris in the blind corners of the dust cup 22 or the debris entangled in the dust cup 22.

[0052] Step S3, convection cleaning stage: control the first fan assembly 11 of the base station 1 and the second fan assembly 21 of the vacuum cleaner 2 to be in operation.

[0053] Specifically, the vacuum cleaner 2 in the convection cleaning stage is connected to the base station 1, and the first fan assembly 11 and the second fan assembly 21 operate simultaneously, forming convection between the vacuum cleaner 2 and the base station 1, further disturbing the debris located in the dead corners of the dust cup 22 or the debris entangled in the dust cup 22, so that the debris located in the dead corners of the dust cup 22 or the debris entangled in the dust cup 22 can be separated from the dead corners or no longer entangled in the dust cup 22.

[0054] The dust discharge control method of the cleaning system of the embodiment of the present application, in the initial dust collection stage, most of the debris is absorbed by the operation of the first fan assembly 11 of the base station 1, and in the first reversing suction stage, the debris in the dead corner of the dust cup 22 or the debris entangled in the dust cup 22 is loosened in advance by the operation of the second fan assembly 21 of the vacuum cleaner 2, and in the convection cleaning stage, convection is generated in the dust cup 22 of the vacuum cleaner 2 by controlling the simultaneous operation of the first fan assembly 11 and the second fan assembly 21, so that the debris located in the dead corner of the dust cup 22 or the debris entangled in the dust cup 22 is separated from the dead corner or no longer entangled in the dust cup 22, thereby improving the dust collection effect of the base station 1; in addition, by utilizing the second fan assembly 21 of the vacuum cleaner 2 to generate convection with the first fan assembly 11, there is no need to set other additional structures on the vacuum cleaner 2, thereby saving costs.

[0055] There is no limitation to the method of confirming that the vacuum cleaner 2 is successfully connected to the base station 1 .

[0056] In some embodiments, the successful docking of the vacuum cleaner 2 and the base station 1 is determined by the connection state of the dust collection port of the base station 1 and the dust discharge port of the dust cup 22. Exemplarily, the dust discharge port is connected to the dust collection port, and the vacuum cleaner 2 and the base station 1 are successfully docked.

[0057] In other embodiments, successful docking is determined by in-place detection of the vacuum cleaner 2, wherein in-place detection refers to detecting whether the vacuum cleaner 2 is in the target position. The target position refers to the position of the vacuum cleaner 2 when the dust collection port of the base station 1 and the dust discharge port of the dust cup 22 are connected.

[0058] In some embodiments, the cleaning system includes a sensing mechanism 3 for detecting the presence of the vacuum cleaner 2 .

[0059] Specifically, in some embodiments, the sensing mechanism 3 includes a first electrode sheet and a second electrode sheet. The first electrode sheet is arranged on the base station 1, and a first sensing circuit electrically connected to the first electrode sheet is arranged on the base station 1. The second electrode sheet is arranged on the vacuum cleaner 2, and a second sensing circuit electrically connected to the second electrode sheet is arranged on the vacuum cleaner 2. When the electrode sheets on the two are connected, the first sensing circuit and the second sensing circuit are turned on, and a sensing signal indicating that the vacuum cleaner 2 is at the target position is sent to the dust exhaust control device.

[0060] In other embodiments, the sensing mechanism 3 includes a position sensor, such as an infrared sensor. A transmitting component of the infrared sensor can be installed on one of the base station 1 and the vacuum cleaner 2, and a receiving component of the infrared sensor can be installed on the other. When the receiving component receives the infrared ray emitted by the transmitting component, a sensing signal indicating that the vacuum cleaner 2 is at the target position is sent to the dust exhaust control device.

[0061] In this way, after receiving the sensing signal, the dust discharge control device can confirm that the vacuum cleaner 2 and the base station 1 are connected, and the judgment is timely and accurate, thereby improving the control accuracy of the dust discharge control device.

[0062] In some embodiments, after the convection cleaning stage, the dust exhaust control method further includes a dust collection stage.

[0063] Step S4, dust collection stage: control the first fan assembly 11 to be in a running state, and control the second fan assembly 21 to be in a closed state.

[0064] It can be understood that during the convection cleaning stage, the convection generated by the simultaneous operation of the first fan assembly and the second fan assembly, although the debris located in the dead corner of the dust cup or the debris entangled in the dust cup is out of the dead corner or no longer entangled in the dust cup, this part of the debris is affected by the first fan assembly and the second fan assembly at the same time, and is easily retained in the dust cup under the influence of convection, and cannot flow toward the base station.

[0065] In this embodiment, during the dust collection stage, the second fan assembly 21 is turned off, so that the debris that has escaped from the dead corner or is no longer entangled on the dust cup 22 is only subjected to the suction action of the first fan assembly 11, and is thereby sucked into the base station 1, thereby achieving the emptying of the debris. Through the convection effect of the debris in the convection cleaning stage, the debris can be quickly cleaned by the base station 1 during the dust collection stage, thereby improving the dust removal efficiency of the base station 1.

[0066] It can be understood that in some examples, after the convection cleaning stage and before the dust collection stage, the dust exhaust control method further includes a second reversing suction stage.

[0067] The second reversing suction stage: the first fan assembly 11 is controlled to be in a closed state, and the second fan assembly 21 is controlled to be in a running state.

[0068] Specifically, after the convection cleaning stage, the debris in the dust cup 22 is loosened again by controlling the operation of the second fan assembly 21 of the vacuum cleaner 2, thereby further reducing the probability that debris is still located in the dead corner of the dust cup 22 or entangled in the dust cup 22 after the convection cleaning stage, thereby increasing the dust collection effect of the base station 1 during the dust collection stage, thereby further improving the dust removal reliability of the cleaning system.

[0069] The switching logic of each working stage is not limited.

[0070] In some embodiments, each working stage is switched by detecting the amount of debris in the dust cup 22 of the vacuum cleaner 2.

[0071] Exemplarily, the cleaning system includes a detection device for detecting the amount of debris in the dust cup 22 and generating a detection signal, and the control device can switch between various working stages according to the detection signal.

[0072] The type of the detection device is not limited. For example, the detection device can be an infrared sensor, a laser radar system, a weight sensor, or an ultrasonic sensor.

[0073] In one embodiment, the detection device may be a video monitoring device. That is, the image in the dust cup 22 is collected by a camera of the video monitoring device, and the collected image in the dust cup 22 is automatically recognized by using machine learning technology to determine the amount of debris in the dust cup 22, and then the working stage is switched according to different amounts of debris.

[0074] It is understandable that the types of detection devices are different and the locations where the detection devices are set are different.

[0075] In one embodiment, the detection device is disposed in the dust cup 22. For example, the detection device is an infrared sensor, including a transmitting end and a receiving end, which is fixedly installed in the dust cup 22. Negative pressure is formed in the dust cup 22. When the debris is discharged through the dust outlet of the dust cup 22, the transmitting end emits infrared light waves, which are scattered after being irradiated to the debris. After the receiving end collects the light, the amount of debris is calculated by comparing the changes in the light before and after.

[0076] In another embodiment, the detection device is disposed outside the dust cup 22. For example, the detection device is a weight sensor, which calculates the amount of debris by detecting the weight change of the dust cup 22.

[0077] That is to say, multiple thresholds corresponding to different working stages are determined for the amount of debris through multiple tests. Exemplarily, a first threshold and a second threshold are determined through tests, wherein the first threshold is greater than the second threshold. The amount of debris in the dust cup 22 is detected by a detection device. If the amount of debris in the dust cup 22 is less than the first threshold, the control enters the first reversing suction stage. If the amount of debris in the dust cup 22 continues to decrease to the second threshold, the control enters the convection cleaning stage.

[0078] In some embodiments, each working stage is switched by recording the operation time of the first fan assembly 11 and the second fan assembly 21 .

[0079] Exemplarily, in some embodiments, the first duration of the cleaning system in the first dust collection stage is recorded. When the first duration reaches a first preset duration, the first fan assembly 11 is turned off and the second fan assembly 21 is turned on, so that the cleaning system switches from the first dust collection stage to the first reversing suction stage.

[0080] Exemplarily, the first time duration may be the time duration that the first fan assembly 11 is in the operating state, or may be the time duration that the second fan assembly 21 is in the closed state.

[0081] The first preset time length may be a pre-set value for characterizing the time length, and is obtained, for example, by performing multiple tests on the cleaning system.

[0082] It can be understood that when the first time reaches the first preset time, the first fan assembly 11 operates for the first preset time, and the second fan assembly 21 is in the off state for the first preset time. The debris in the dust cup 22 of the vacuum cleaner 2 is basically sucked into the base station 1 by the first fan assembly 11, and a small amount of debris located in the dead corner of the dust cup 22 or the debris entangled in the dust cup 22 cannot be sucked by the first fan assembly 11. At this time, by turning off the first fan assembly 11 and turning on the second fan assembly 21, the cleaning system switches from the first dust collection stage to the first reversing suction stage, and then further discharges dust from the dust cup 22.

[0083] In this embodiment, by recording the first duration, the working phase of the cleaning system can be adjusted according to the current dust removal demand of the vacuum cleaner 2, which is intelligent and convenient and improves the user experience.

[0084] Exemplarily, in some embodiments, the second duration of the cleaning system in the first reversing suction stage is recorded, and when the second duration reaches a second preset duration, the first fan assembly 11 is turned on to switch the cleaning system from the first reversing suction stage to the convection cleaning stage.

[0085] Exemplarily, the second time period may be the time period during which the first fan assembly 11 is in the closed state, or the time period during which the second fan assembly 21 is in the operating state.

[0086] The second preset time length may be a pre-set value for characterizing the time length, and is obtained, for example, by performing multiple tests on the cleaning system.

[0087] It can be understood that when the second time reaches the second preset time, the first fan assembly 11 is in the closed state for the second preset time, and the second fan assembly 21 is in the operating state for the second preset time. The debris located in the blind corner of the dust cup 22 or the debris entangled in the dust cup 22 is disturbed by the suction action of the second fan assembly 21, but there is still a small amount of debris entangled in the dust cup 22 that cannot be sucked by the second fan assembly 21. By turning on the first fan assembly 11, the cleaning system switches from the first reversing suction stage to the convection cleaning stage, and convection is generated to disturb the debris entangled in the dust cup 22, thereby reducing the phenomenon of stubborn debris remaining in the dust cup 22 and improving the dust collection effect of the base station 1.

[0088] In this embodiment, by recording the second time length, the working phase of the cleaning system can be adjusted according to the current dust removal demand of the vacuum cleaner 2, which is intelligent and convenient and improves the user experience.

[0089] Exemplarily, in some embodiments, the third duration that the cleaning system is in the convection cleaning stage is recorded. When the third duration reaches a third preset duration, the first fan assembly 11 is turned on and the second fan assembly 21 is turned off, so that the cleaning system switches from the convection cleaning stage to the dust collection stage.

[0090] Exemplarily, the third time duration may be the time duration during which the first fan assembly 11 is in operation, or may be the time duration during which the second fan assembly 21 is in operation.

[0091] The third preset time length may be a pre-set value for characterizing the time length, and is obtained, for example, by performing multiple tests on the cleaning system.

[0092] It can be understood that when the third time reaches the third preset time, that is, the first fan assembly 11 and the second fan assembly 21 have been running for the third preset time, the debris located in the dead corner of the dust cup 22 or the debris entangled in the dust cup 22 is disturbed by the convection of the first fan assembly 11 and the second fan assembly 21. By turning off the second fan assembly 21, the cleaning system switches from the convection cleaning stage to the dust collection stage, thereby achieving the removal of stubborn debris remaining in the dust cup 22 disturbed by the convection cleaning stage, thereby improving the dust collection effect of the base station 1.

[0093] In this embodiment, by recording the third time length, the working phase of the cleaning system can be adjusted according to the current dust removal demand of the vacuum cleaner 2, which is intelligent and convenient and improves the user experience.

[0094] In other embodiments, when the third time period reaches a third preset time period, the second fan assembly 21 may be turned on and the first fan assembly 11 may be turned off, so that the cleaning system switches from the convection cleaning stage to the second reversing suction stage.

[0095] In this way, when the first fan assembly 11 and the second fan assembly 21 are both running for the third preset time period, the debris located in the dead corner of the dust cup 22 or the debris entangled on the dust cup 22 will be separated from the dead corner or no longer entangled on the dust cup 22 due to the action of convection. By turning off the first fan assembly 11 and turning on the second fan assembly 21, the probability of there being debris located in the dead corner of the dust cup 22 or entangled on the dust cup 22 after the convection cleaning stage is further reduced, thereby increasing the dust collection effect of the base station 1.

[0096] In some examples, the fourth duration of the cleaning system in the second reversing suction stage is recorded. When the fourth duration reaches a fourth preset duration, the first fan assembly 11 is turned on and the second fan assembly 21 is turned off, so that the cleaning system switches from the second reversing suction stage to the dust collection stage.

[0097] Exemplarily, the fourth time duration may be the time duration during which the first fan assembly 11 is in the closed state, or the time duration during which the second fan assembly 21 is in the operating state.

[0098] The fourth preset time length may be a pre-set value for characterizing the time length, and is obtained, for example, by performing multiple tests on the cleaning system.

[0099] It can be understood that when the fourth time period reaches the fourth preset time period, the first fan assembly 11 is in the closed state for the fourth preset time period, and the second fan assembly 21 is in the operating state for the fourth preset time period, further reducing the probability of debris being located in the dead corner of the dust cup 22 or being entangled in the dust cup 22. By turning on the first fan assembly 11 and turning off the second fan assembly 21, the cleaning system switches from the second reversing suction stage to the dust collection stage, thereby achieving the removal of stubborn debris and improving the dust collection effect of the base station 1.

[0100] In this embodiment, by recording the fourth time duration, the working phase of the cleaning system can be adjusted according to the current dust removal demand of the vacuum cleaner 2, which is intelligent and convenient and improves the user experience.

[0101] According to a second aspect of an embodiment of the present application, a dust exhaust control device for a cleaning system is provided. The dust exhaust control device includes a determination module and a control module.

[0102] It is understandable that the determination module and the control module can be independent hardware modules divided according to functions, or integrated devices with integrated functions. Different functional modules, whether independent modules or integrated devices, all belong to the protection scope of this application as long as they adopt the functions of the controller of the embodiment of this application.

[0103] The determination module is used to confirm that the vacuum cleaner 2 is successfully docked with the base station 1 and output dust removal information.

[0104] Exemplarily, the determination module can confirm that the vacuum cleaner 2 is successfully docked with the base station 1 by determining that the dust collection port of the base station 1 and the dust discharge port of the dust cup 22 are connected, thereby outputting dust discharge information.

[0105] The control module is used to control the first fan assembly 11 to be in an operating state and the second fan assembly 21 to be in an off state according to the dust exhaust information, so that the cleaning system enters the first dust collection stage; after the first dust collection stage, the first fan assembly 11 is controlled to enter the first reversing suction stage, and after the first reversing suction stage, the first fan assembly 11 of the base station 1 and the second fan assembly 21 of the vacuum cleaner 2 are controlled to be in an operating state, so that the cleaning system enters the convection cleaning stage.

[0106] In some embodiments, the dust exhaust control device further includes a timing module, and the timing module is used to record the first duration of the cleaning system in the first dust collection stage.

[0107] Exemplarily, the timing module may be a timer made of a crystal oscillator commonly used in the market.

[0108] The determination module is used to compare the first time length with the first preset time length, and when the first time length reaches the first preset time length, it is determined that the cleaning system intends to enter the first reversing suction stage.

[0109] It should be noted that intended entry refers to preparation for entry. After the determination module makes a judgment, the cleaning system is controlled by the control module to enter the first reversing suction stage.

[0110] The control module is used to: according to the information of the determination module that the first reversing suction stage is to be entered, control the first fan assembly 11 to be turned off and the second fan assembly 21 to be turned on, so that the cleaning system switches from the initial dust collection stage to the first reversing suction stage.

[0111] That is to say, after the first preset duration of the first dust collection stage, the cleaning system determines that the module sends a signal to end the first dust collection stage, and controls the first fan assembly 11 to be turned off and the second fan assembly 21 to be turned on through the control module, and the cleaning system enters the first reversing suction stage.

[0112] It can be understood that when the first time reaches the first preset time, the first fan assembly 11 operates for the first preset time, and the second fan assembly 21 is in the off state for the first preset time. The debris in the dust cup 22 of the vacuum cleaner 2 is basically sucked into the base station 1 by the first fan assembly 11, and a small amount of debris located in the dead corner of the dust cup 22 or the debris entangled in the dust cup 22 cannot be sucked by the first fan assembly 11. At this time, by turning off the first fan assembly 11 and turning on the second fan assembly 21, the cleaning system switches from the first dust collection stage to the first reversing suction stage, and then further discharges dust from the dust cup 22.

[0113] In some embodiments, the timing module is further used to record a second duration of the cleaning system in the first reversing suction phase.

[0114] The determination module is used to compare the second time length with the second preset time length, and when the second time length reaches the second preset time length, it is determined that the cleaning system intends to enter the convection cleaning stage.

[0115] The control module is used to: according to the information of the determination module that the convection cleaning stage is to be entered, control the first fan assembly 11 of the base station and the second fan assembly 21 of the vacuum cleaner to be in operation, so that the cleaning system switches from the first reversing suction stage to the convection cleaning stage.

[0116] That is to say, after the second preset time in the first reversing suction stage, the cleaning system determines that the module sends a signal to end the first reversing suction stage, and the control module controls the first fan assembly 11 and the second fan assembly 21 to be in operation, and the cleaning system enters the convection cleaning stage.

[0117] It can be understood that when the second time reaches the second preset time, the first fan assembly 11 is in the closed state for the second preset time, and the second fan assembly 21 is in the operating state for the second preset time. The debris located in the blind corner of the dust cup 22 or the debris entangled in the dust cup 22 is disturbed by the suction action of the second fan assembly 21, but there is still a small amount of debris entangled in the dust cup 22 that cannot be sucked by the second fan assembly 21. By turning on the first fan assembly 11, the cleaning system switches from the first reversing suction stage to the convection cleaning stage, and convection is generated to disturb the debris entangled in the dust cup 22, thereby reducing the phenomenon of stubborn debris remaining in the dust cup 22 and improving the dust collection effect of the base station 1.

[0118] In some embodiments, the timing module is further used to record a third duration of the cleaning system in the convection cleaning stage.

[0119] The determination module is used to compare the third time length with the third preset time length, and when the third time length reaches the third preset time length, it is determined that the cleaning system intends to enter the dust collection stage.

[0120] The control module is used to: according to the information of the determination module that the dust collection stage is to be entered, control the first fan assembly 11 of the base station 1 to be in operation, and control the second fan assembly 21 of the vacuum cleaner to be turned off, so that the cleaning system switches from the convection cleaning stage to the dust collection stage.

[0121] That is to say, after the third preset time of the convection cleaning stage, the cleaning system determines that the module sends a signal to end the convection cleaning stage, controls the first fan component 11 to be in operation through the control module, controls the second fan component 21 of the vacuum cleaner to be turned off, and the cleaning system enters the dust collection stage.

[0122] It can be understood that when the third time reaches the third preset time, that is, the first fan assembly 11 and the second fan assembly 21 have been running for the third preset time, the debris located in the dead corner of the dust cup 22 or the debris entangled in the dust cup 22 is disturbed by the convection of the first fan assembly 11 and the second fan assembly 21. By turning off the second fan assembly 21, the cleaning system switches from the convection cleaning stage to the dust collection stage, thereby achieving the removal of stubborn debris remaining in the dust cup 22 disturbed by the convection cleaning stage, thereby improving the dust collection effect of the base station 1.

[0123] In some other examples, the determination module is used to compare the third time length with a third preset time length, and when the third time length reaches the third preset time length, it is determined that the cleaning system intends to enter the second reversing suction stage.

[0124] The control module is used to: according to the information of the determination module that the second reversing suction stage is to be entered, control the second fan assembly 21 of the vacuum cleaner 2 to be in operation, and control the first fan assembly 11 of the base station 1 to be turned off, so that the cleaning system switches from the convection cleaning stage to the second reversing suction stage.

[0125] That is to say, after the third preset time in the convection cleaning stage, the cleaning system determines that the module sends a signal to end the second reversing suction stage, and controls the first fan component 11 to be turned off and the second fan component 21 to be turned on through the control module, and the cleaning system enters the second reversing suction stage.

[0126] In some examples, the timing module is further used to record a fourth duration of the cleaning system in the second reversing suction phase.

[0127] The determination module is used to compare the fourth time period with the fourth preset time period, and when the fourth time period reaches the fourth preset time period, it is determined that the cleaning system intends to enter the dust collection stage.

[0128] The control module is used to: according to the information of the determination module that the dust collection stage is to be entered, control the first fan assembly 11 of the base station 1 to be in operation, and control the second fan assembly 21 of the vacuum cleaner 2 to be turned off, so that the cleaning system switches from the second reversing suction stage to the dust collection stage.

[0129] That is to say, after the fourth preset time in the second reversing suction stage, the cleaning system determines that the module sends a signal to end the second reversing suction stage, and controls the first fan assembly 11 to turn on and the second fan assembly 21 to turn off through the control module, and the cleaning system enters the dust collection stage.

Once an abnormal situation, such as a fault or overload, is found, an alarm can be sent in time to remind the operator to take corresponding measures to avoid further damage; in addition, intelligent control and adjustment are performed according to real-time data to improve energy efficiency and reduce energy consumption. For example, the speed of the first fan assembly 11 and the second fan assembly 21 is automatically adjusted according to the load conditions to achieve the best operating effect.
