Detailed Description of Embodiments

[0021] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the embodiments described herein are not limited to the present invention.The specific embodiments described are only for illustration and explanation of the present invention, and the scope of protection of the present invention is not limited to the specific embodiments described below.

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of the present invention are used to distinguish similar objects, rather than to limit a specific order or sequence. It should be understood that the above terms can be interchanged where appropriate so that the embodiments described in the present invention can be implemented in an order other than that described in the present invention. In addition, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or devices.

[0023] As shown in FIG3, the cleaning system includes a cleaning device 100 and a cleaning base station 200 arranged in cooperation. The cleaning device 100 includes a body and a cleaning fan 101, a dust collection assembly 102 and a cleaning filter 103 disposed on the body. The cleaning fan 101 is disposed corresponding to the dust collection assembly 102, and an air duct is provided on the body. The air duct is sequentially connected to the dust suction port of the cleaning device 100, the dust collection assembly 102, the cleaning filter 103 and the cleaning fan 101, so that the cleaning device 100 can be cleaned by forming a negative pressure through the cleaning fan 101. The cleaning station 200 has a dust collection function. The cleaning filter 103 is installed in the air duct between the cleaning fan 101 and the dust collection assembly 102 to effectively clean the exhaust air. The cleaning station 200 includes a dust collection fan 201 and a dust collection container 202. The dust collection fan 201 is installed in relation to the dust collection container 202, and the dust collection container 202 is installed in relation to the dust collection assembly 102. When the cleaning equipment 100 and the cleaning station 200 are in a docked state, the switch between the dust collection container 202 and the dust collection assembly 102 is opened, so that an air duct is formed between the dust collection container 202 and the dust collection assembly 102. The operation of the dust collection fan 201 can generate negative pressure. Under the action of negative pressure, the dust and dirt in the dust collection assembly 102 can be sucked into the dust collection container 202 through the air duct, thereby realizing the centralized collection of dust, fine particles, hair and other dirt collected by the cleaning equipment 100 by the cleaning station 200.

[0024] It should be noted that the dust collection assembly 102 includes, but is not limited to, a dust collection box or a dust collection bag; the cleaning filter 103 includes, but is not limited to, a HEPA filter. It is conceivable that the cleaning filter 103 may also include a sponge filter layer, a composite filter assembly, etc. Specification 4 / 11 pages 8 CN 121549693 A

[0025] In addition, the cleaning equipment includes, but is not limited to, mobile cleaning robots and handheld cleaning devices, wherein the cleaning equipment at least has a vacuuming function, for example, the cleaning equipment is a sweeping robot or a handheld vacuum cleaner.

[0026] The first aspect of the present invention provides an automatic dust collection method applied to the above-mentioned cleaning system, as shown in FIG1. ​​The automatic dust collection method includes the following steps:

[0027] S101, detecting that the cleaning device 100 and the cleaning base station 200 are properly docked and obtained a first dust collection command signal; S102, in response to the first dust collection command signal, controlling the cleaning fan 101 to blow air towards the cleaning filter 103 to blow the dirt on the cleaning filter 103 into the dust collection assembly 102, and then controlling the dust collection fan 201 to extract the dirt in the dust collection assembly 102 into the dust collection container 202. By detecting the docking signal between the cleaning equipment 100 and the cleaning base station 200, when the two are docked, the cleaning fan 101 of the cleaning equipment 100 can be controlled to blow air towards the cleaning filter 103, that is, the cleaning fan 101 can be controlled to reverse (opposite to the rotation direction of the cleaning fan 101 that performs the dust suction function of the cleaning equipment 100). This can blow the dirt on the cleaning filter 103 into the dust collection assembly 102 of the cleaning equipment 100, and also make the dust and dirt in the dust collection assembly 102 rise, so that the dust collection fan 201 of the base station 200 can draw the dirt in the dust collection assembly 102 into the dust collection container 201 of the cleaning base station 200. Without setting up an additional air duct, only the original air duct between the cleaning fan 101 and the dust collection assembly 102 is used, and the dust collection assembly 102 and the dust collection container 202 are in the docked state of the cleaning equipment 100 and the cleaning base station 200. The air duct between the two can improve the cleanliness of the dust collection component 102 and clean the HEPA filter element at the same time through the automatic dust collection method of the present invention, avoiding the problem of increasing the complexity of structural improvement due to the additional air duct between the cleaning equipment and the cleaning base station.

[0028] In step S102, the duration and / or number of times the cleaning fan 101 blows air towards the cleaning filter element 103 can be preset to ensure the cleaning effect of the cleaning filter element 103.

[0029] Further, after the first dust collection command signal is executed, the present invention obtains the filter element cleaning detection signal. The method also includes: S103, in response to the filter element cleaning detection signal, controlling the cleaning fan 101 to blow air towards the cleaning filter element 103; S104, detecting the wind force signal before and after passing through the cleaning filter element 103, obtaining the wind force attenuation value, and comparing the wind force attenuation value with the preset value; if the wind force attenuation value is higher than the preset value, obtaining and executing the first dust collection command signal again; if the wind force attenuation value does not exceed the preset value, ending the filter element cleaning detection operation.

[0030] That is, after the first integrated command signal is completed, the cleaning fan 101 is controlled to backflush again. Since the blown airflow will pass through the cleaning filter 103, and the cleaning filter 103 has wind resistance, the airflow after passing through the cleaning filter 103...The wind force will decrease, and the resistance of the cleaning filter 103 to airflow is affected by the degree of clogging of its filter gaps by dust particles. Therefore, by measuring the wind force signals before and after the cleaning filter 103, the cleanliness of the cleaning filter 103 can be determined based on the magnitude of the wind force attenuation value. That is, if the wind force attenuation value is higher than the preset value, the dust particles on the cleaning filter 103 are not cleaned sufficiently, which has a significant impact on the wind force. At this point, the first integrated command signal is executed to clean the cleaning filter. The preset value of the wind force attenuation value can be set with a compensation value based on the wind force attenuation value obtained from testing the unused cleaning filter 103. For example, it can be compensated by 5% to 10%. This value is for illustration only, and the specific value can be set according to actual needs. The aforementioned wind force signals can be obtained by setting wind force sensors in the air ducts corresponding to the front and rear ends of the cleaning filter 103. These wind force sensors include, but are not limited to, wind speed sensors and wind pressure sensors.

[0031] It should be noted that the wind force signal detection method of the above-mentioned cleaning filter 103 can be continuous detection, which can effectively improve the judgment response speed and make it more accurate and timely; it is conceivable that the wind force signal detection method of the above-mentioned cleaning filter 103 can also be intermittent detection, that is, setting a fixed frequency and detecting according to the set time. Compared with continuous detection, it can reduce the energy consumption of the wind sensor, save energy, and improve the service life of the wind sensor. The specific detection time interval can be set according to the actual situation.

[0032] On the basis of setting a wind sensor, in step S102, during the process of controlling the cleaning fan 101 to blow air towards the cleaning filter 103, the wind force attenuation value at the front and rear ends of the cleaning filter 103 can be detected in real time. The running time of the cleaning fan 101 can be set until the wind force attenuation value decreases to a preset value.

[0033] It should be noted that after prolonged use, the cleaning filter 103 cannot be effectively cleaned even after being backflushed by the cleaning fan 101, and needs to be replaced. After responding to and executing the filter cleaning detection signal multiple times, such as three, four, or five times (the specific number of times can be set according to actual needs), the wind force attenuation value always exceeds the preset value. Alternatively, in the embodiment where the wind force attenuation value is detected in real time in step S102 above to control the running time of the cleaning fan 101 according to the wind force attenuation value, if the wind force attenuation value cannot be reduced to the preset value within the set time, the cleaning system is controlled to issue a prompt signal to remind the user to replace the cleaning filter 103, so that the air outlet of the cleaning fan 101 is clean, the equipment is prevented from overheating, and the dust collection function of the cleaning equipment 100 is ensured to operate normally. This prompt signal includes, but is not limited to, sound prompts, warning light prompts, text prompts, and remote operation terminal (e.g., mobile phone, tablet) information prompts.

[0034] In step S102, during the operation of controlling the cleaning fan 101 to blow air towards the cleaning filter 103 to blow the dirt on the cleaning filter 103 into the dust collection assembly 102, the present invention operates the cleaning fan 101 at intervals at a set frequency. The cleaning fan 101 can have two operating modes with opposite blowing directions. As a specific implementation of interval operation, the cleaning fan 101 can operate at intervals with a single blowing direction to vibrate the cleaning filter 103 and improve the shaking effect of dust particles attached to the cleaning filter 103. As another specific implementation of interval operation, the cleaning fan 101 can achieve alternating interval operation with opposite blowing directions. By switching the airflow direction back and forth, the vibration effect of the cleaning filter 103 is further enhanced, and the shaking effect of dust particles attached to the cleaning filter 103 is further improved. In addition, the above-mentioned intermittent operation can be achieved by controlling the control current signal of the cleaning fan 101; when a connecting pipe is provided between the cleaning fan 101 and the cleaning filter 103, a solenoid valve can also be provided in the connecting pipe, and the intermittent operation of the cleaning fan 101 can be achieved by controlling the on and off of the solenoid valve through the current signal. As shown in Figure 2, the automatic dust collection method of the present invention further includes: S201, detecting that the cleaning equipment 100 and the cleaning base station 200 are properly connected and obtaining a second dust collection command signal; S202, responding to the second dust collection command signal, controlling the dust collection fan 201 to extract the dirt in the dust collection component 102 into the dust collection container 202.

[0035] It should be noted that the execution priority of the second dust collection command signal and the execution priority of the first integrated command signal can be set according to the actual situation. Through the second dust collection command signal, the dirt in the dust collection component 102 can be further cleaned, achieving double cleaning and ensuring that the dirt in the dust collection component 102 is thoroughly cleaned.

[0036] Preferably, the execution priority of the second dust collection command signal is higher than that of the first dust collection command signal, so that before cleaning the cleaning filter 103, the dust and dirt in the dust collection assembly 102 can be collected into the base station 200 first, reducing the amount of dirt in the dust collection assembly 102; when the first dust collection command signal is executed again, the probability of the raised dust re-attaching to the cleaning filter 103 is effectively reduced, further improving the cleaning efficiency and cleanliness of the cleaning filter 103.

[0037] Further, in step S202, in response to the second dust collection command signal, after controlling the cleaning fan 101 to run and raise the dirt in the dust collection assembly 102, the dust collection fan 201 is then controlled to extract the dirt in the dust collection assembly 102 into the dust collection container 202. Instruction manual, pages 6 / 11, 10 CN 121549693 A

[0038] When the cleaning device 100 and the cleaning base station 200 are docked, the cleaning of the cleaning device 100 can be controlled.The operation of the fan 101 can lift the dirt in the dust collection assembly 102. The dust floats in the dust collection assembly 102, which can shake the heavier dirt at the bottom of the dust collection assembly 102 and break up the dirt that has accumulated together. This makes it easier for the dust collection fan 201 to draw the dirt in the dust collection assembly 102 into the dust collection container 202. Without setting up additional air ducts, by only using the original air duct between the cleaning fan 101 and the dust collection assembly 102, and the air duct between the dust collection assembly 102 and the dust collection container 202 when the cleaning equipment 100 and the cleaning base station 200 are connected, the cleanliness of the dust collection assembly 102 can be effectively improved by the automatic dust collection method of the present invention. This avoids the problem of increasing the complexity of structural modifications caused by adding additional air ducts between the cleaning equipment and the cleaning base station.

[0039] It should be noted that in step S202, the cleaning fan 101 can rotate forward, reverse, or alternately. The duration and / or number of times the cleaning fan 101 operates can be set according to actual needs, as long as the dirt in the dust collection assembly 102 is sufficiently lifted.

[0040] Further, in a preferred embodiment, step S202 specifically includes: S202-1, responding to the second dust collection command signal, controlling the cleaning fan 101 to operate and lift the dirt in the dust collection assembly 102; S202-2, detecting the dust concentration signal in the dust collection assembly 102 in real time and obtaining the rate of change of the dust concentration signal; S202-3, responding to the rate of change of the current dust concentration signal being less than or equal to a preset value, controlling the dust collection fan 201 to extract the dirt in the dust collection assembly 102 into the dust collection container 202.

[0041] In this embodiment, a dust sensor can be installed in the dust collection component 102. The dust sensor emits a light signal. The degree of interference of dust particles of different concentrations in the dust collection component 102 on the light signal is different. The higher the dust concentration, the higher the light intensity attenuation. After the light signal is captured by the photodetector, the relative attenuation rate of the electrical signal is analyzed and the dust concentration is calculated. When the dust and dirt attached to the dust collection component 102 are lifted, the dust concentration in the dust collection component 102 will increase. After the dust and dirt are lifted, the dust concentration will tend to a relatively stable value. Thus, the change rate of the dust concentration signal can be used to determine whether the dust and dirt in the dust collection component 102 are sufficiently lifted. When the change rate of the dust concentration signal is less than or equal to a preset value, the cleaning fan 101 is stopped and the dust collection fan 201 is controlled to run to extract the lifted dust and dirt, which effectively improves the cleanliness of the dust collection component 102 and can lift enough dust to clean the base station 200. It can also effectively improve the dust collection efficiency and reduce the operating energy consumption.

[0042] Further, after the first dust collection command signal or the second dust collection command signal of the present invention is executed, a dust collection component cleaning detection signal is obtained. The method further includes:In response to the cleaning detection signal of the dust collection component, the detection signal of the cleanliness detection sensor inside the dust collection component 102 is acquired to determine the cleanliness inside the dust collection component 102; when the cleanliness inside the dust collection component 102 is lower than the preset value, the second dust collection command signal is acquired and executed again; when the cleanliness inside the dust collection component 102 is greater than or equal to the preset value, the dust collection component cleaning detection operation ends.

[0043] The operating conditions of the cleaning equipment 100 are different each time, and the accumulation of dirt inside the dust collection component 102 is also different. If there is a lot of dirt and it is difficult to clean, the cleanliness inside the cleaning box 102 can be effectively known through the above-mentioned dust collection component cleaning detection signal. In the case of insufficient cleanliness, the dirt inside the cleaning box 102 can be effectively cleaned by executing the second dust collection command signal multiple times to ensure the stable operation of the next vacuuming operation. If the cleanliness of the dust collection component 102 still fails to meet the cleaning requirements after responding to and executing the dust collection component cleaning detection signal multiple times, such as three, four, or five times (the specific number of times can be set according to actual needs), the dust collection component cleaning detection signal can be stopped, and the cleaning system can be controlled to issue a prompt signal (page 7 / 11 of the manual, CN 121549693 A) to remind the user that there is a malfunction in cleaning the dirt inside the dust collection component 102, prompting the user to troubleshoot the fault or manually disassemble the dust collection component 102 for cleaning. This prompt signal includes, but is not limited to, sound prompts, warning light prompts, text prompts, and information prompts from remote operation terminals (such as mobile phones and tablets).

[0044] Specifically, as a specific embodiment of the cleanliness detection sensor, the cleanliness detection sensor includes a pressure sensor, which is adapted to monitor the weight signal of the dust collection assembly 102. The step of obtaining the detection signal of the cleanliness detection sensor in the dust collection assembly 102 to determine the cleanliness of the dust collection assembly 102 includes: obtaining the weight value of the dust collection assembly 102, obtaining the weight value of the dirt in the dust collection assembly 102, and comparing the weight value of the dirt with a preset value; if the weight value of the dirt does not exceed the preset value, determining that the cleanliness of the dust collection assembly 102 is greater than or equal to the preset value; if the weight value of the dirt is higher than the preset value, determining that the cleanliness of the dust collection assembly 102 is lower than the preset value.

[0045] After the dust collection fan 201 extracts the dirt from the dust collection assembly 102, the dust and dirt in the dust collection assembly 102 will be in a state of being raised. In order to avoid the dirt not falling into the dust collection assembly 102, preferably, the weight value of the dirt can be detected after the dust collection fan 201 has stopped running for a certain period of time, to ensure that the cleanliness judgment result of the dust collection assembly 102 is accurate and to improve the cleanliness of the dirt in the dust collection assembly 102.

[0046] Specifically, as another specific embodiment of the cleanliness detection sensor, the cleanliness detection sensor includes a photoelectric sensor. The photoelectric sensor is suitable for monitoring the dust concentration signal in the dust collection assembly 102 and obtaining the cleanliness of the dust collection assembly 102.The cleanliness detection sensor's detection signal, used to determine the cleanliness of the dust collection assembly 102, includes the following steps: acquiring the dust concentration of the dust collection assembly 102 and comparing it with a preset concentration; if the dust concentration does not exceed the preset concentration, determining that the cleanliness of the dust collection assembly 102 is greater than or equal to the preset value; if the dust concentration is higher than the preset concentration, determining that the cleanliness of the dust collection assembly 102 is lower than the preset value.

[0047] In contrast to the pressure sensor, to ensure the accuracy of the photoelectric sensor's determination of the cleanliness of the dust collection assembly 102, preferably, the dust concentration signal of the dust collection assembly 102 can be detected immediately after the dust collection fan 201 stops running, so as to obtain data under the condition that the dust and dirt are sufficiently raised.

[0048] The above-mentioned photoelectric sensor can be an optocoupler sensor or a dust sensor; wherein, the optocoupler sensor is based on the principle of optical coupling and is composed of a light-emitting diode and a phototransistor. It controls the switching logic by detecting the on / off state of the light beam. The penetrating power of light of different wavelengths is different. The corresponding wavelength of light can be set according to the set dust concentration so that when the dust concentration does not exceed the preset concentration, the light signal can irradiate the phototransistor to form a photocurrent. When the dust concentration is higher than the preset concentration, the light of this wavelength cannot penetrate the dust to irradiate the phototransistor to form a photocurrent, thereby judging the relationship between the cleanliness of the dust collection component 102 and the preset value; the dust sensor is based on the principle of light heat dissipation and uses a laser or LED light source to irradiate air particles. The higher the dust concentration, the higher the light intensity attenuation. After the light signal is captured by the photodetector, the relative attenuation rate of the electrical signal is analyzed and the dust concentration is calculated.

[0049] It should be noted that the two specific implementations of the above-mentioned cleanliness detection sensor can be set separately, that is, only a pressure sensor or a photoelectric sensor can be set; or both can be set. Through the dual detection of the pressure sensor and the photoelectric sensor, the cleanliness judgment structure of the dust collection component 102 can be made more accurate. As long as the detection signal of one of the pressure sensor and the photoelectric sensor meets the trigger condition of insufficient cleanliness, the second dust collection command signal can be acquired and executed again to clean the dust collection component 102 again.

[0050] In the above steps 101 and 201, the docking signal between the cleaning device 100 and the cleaning base station 200 can be determined by the docking current signal between the two to determine whether the docking is in place. Specifically, a pair of electrical connection terminals are provided between the tail end of the cleaning device 100 and the cleaning base station 200. When this pair of electrical connection terminals are in contact, a docking current signal is formed between the two. Alternatively, a displacement sensor may be installed on the cleaning base station 200. When the cleaning equipment 100 docks with the cleaning base station 200, the displacement sensor is used to detect the displacement signal of the cleaning equipment 100 so as to send a docking signal when it moves to the docking position.

[0051] A second aspect of the present invention also provides an automatic dust collection system applied to a cleaning system. The cleaning system includes a cleaning device 100 and a cleaning base station 200 configured in cooperation. The cleaning device 100 includes a body and a cleaning fan 101, a dust collection component 102, and a cleaning filter 103 disposed on the body. The cleaning fan 101 is disposed corresponding to the dust collection component 102, and the cleaning filter 103 is disposed on the air duct between the cleaning fan 101 and the dust collection component 102. The cleaning base station 200 includes a dust collection fan 201 and a dust collection container 202. The dust collection fan 201 is disposed corresponding to the dust collection container 202, and the dust collection container 202 is configured to cooperate with the dust collection component 102. Referring to FIG4, the automatic dust collection system 1 includes: an instruction acquisition module 2, used to detect that the cleaning device 100 and the cleaning base station 200 are properly docked and acquire a first dust collection instruction signal. The control module 3 is used to control the cleaning fan 101 to blow air towards the cleaning filter 103 in response to the first dust collection command signal, so as to blow the dirt on the cleaning filter 103 into the dust collection assembly 102, and then control the dust collection fan 201 to extract the dirt in the dust collection assembly 102 into the dust collection container 202.

[0052] Further, the automatic dust collection system of the present invention is also provided with a wind force sensor, which includes, but is not limited to, a wind speed sensor and a wind pressure sensor. The control module 3 is configured to: acquire the filter cleaning detection signal after the first dust collection command signal is executed; control the cleaning fan 101 to blow air towards the cleaning filter 103 in response to the filter cleaning detection signal; detect the wind force signal before and after the cleaning filter 103, obtain the wind force attenuation value, and compare the wind force attenuation value with a preset value; if the wind force attenuation value is higher than the preset value, acquire and execute the first dust collection command signal again; if the wind force attenuation value does not exceed the preset value, end the filter cleaning detection operation.

[0053] Based on the wind force sensor, the control module 3 can detect the wind force attenuation value at the front and rear ends of the cleaning filter 103 in real time while controlling the cleaning fan 101 to blow air towards the cleaning filter 103. The running time of the cleaning fan 101 can be set until the wind force attenuation value decreases to a preset value.

[0054] It should be noted that when the instruction acquisition module 2 detects that the cleaning device 100 and the cleaning base station 200 are properly connected, it will also acquire a second dust collection instruction signal. The control module 3 is also configured to: respond to the second dust collection instruction signal and control the dust collection fan 201 to extract the dirt in the dust collection component 102 into the dust collection container 202; the control module 3 executes the second dust collection instruction signal with higher priority than the first integrated instruction signal, so that before cleaning the cleaning filter 103, the dust and dirt in the dust collection component 102 can be collected into the base station 200 first, reducing the amount of dirt in the dust collection component 102; when the first integrated instruction signal is executed, the control module 3 executes the second dust collection instruction signal with higher priority than the first integrated instruction signal.When the dust collection command signal is received, the probability of the raised dust re-attaching to the cleaning filter element 103 is effectively reduced, further improving the cleaning efficiency and cleanliness of the cleaning filter element 103.

[0055] Further, the control module 3 is configured to: respond to the second dust collection command signal, control the cleaning fan 101 to run and raise the dirt in the dust collection assembly 102, and then control the dust collection fan 201 to extract the dirt in the dust collection assembly 102 into the dust collection container 202.

[0056] In a preferred embodiment, the automatic dust collection system of the present invention is equipped with a dust sensor, which responds to the second dust collection command signal, controls the cleaning fan 101 to run and raise the dirt in the dust collection assembly 102; detects the dust concentration signal in the dust collection assembly 102 in real time, and obtains the rate of change of the dust concentration signal; responds to the fact that the rate of change of the dust concentration signal is less than or equal to a preset value, controls the dust collection fan 201 to extract the dirt in the dust collection assembly 102 into the dust collection container 202.

[0057] After the first dust collection command signal or the second dust collection command signal is executed, the dust collection component cleaning detection signal is acquired. The control module 2 is configured to: acquire the dust collection component cleaning detection signal; in response to the dust collection component cleaning detection signal, acquire the detection signal of the cleanliness detection sensor in the dust collection component 102 to determine the cleanliness in the dust collection component 102; when the cleanliness in the dust collection component 102 is lower than the preset value, acquire and execute the second dust collection command signal again; when the cleanliness in the dust collection component 102 is greater than or equal to the preset value, end the dust collection component cleaning detection operation.

[0058] Specifically, as a specific embodiment of the cleanliness detection sensor, the cleanliness detection sensor includes a pressure sensor, which is adapted to monitor the weight signal of the dust collection assembly 102, obtain the detection signal of the cleanliness detection sensor in the dust collection assembly 102, and the control module 2 is used to obtain the weight value of the dust collection assembly 102, obtain the weight value of the dirt in the dust collection assembly 102, and compare the weight value of the dirt with a preset value; if the weight value of the dirt does not exceed the preset value, it is determined that the cleanliness in the dust collection assembly 102 is greater than or equal to the preset value; if the weight value of the dirt is higher than the preset value, it is determined that the cleanliness in the dust collection assembly 102 is lower than the preset value.

[0059] As another specific embodiment of the cleanliness detection sensor, the cleanliness detection sensor includes a photoelectric sensor, which can be an optocoupler sensor or a dust sensor. The photoelectric sensor is suitable for monitoring the dust concentration signal in the dust collection assembly 102. The control module 2 is used to acquire the dust concentration in the dust collection assembly 102 and compare the dust concentration with a preset concentration. If the dust concentration does not exceed the preset concentration, it is determined that the cleanliness in the dust collection assembly 102 is greater than or equal to the preset value; if the dust concentration is higher than the preset concentration, it is determined that the cleanliness in the dust collection assembly 102 is lower than the preset value.

[0060] A third aspect of the present invention provides a cleaning system, as shown in FIG3. The cleaning system includes a controller 300, a cleaning device 100 and a cleaning base station 200 configured in conjunction with the cleaning device 100. The cleaning device 100 includes a body and a cleaning fan 101, a dust collection assembly 102 and a cleaning filter 103 disposed on the body. The cleaning fan 101 is disposed corresponding to the dust collection assembly 102, and the cleaning filter 103 is disposed on the air duct between the cleaning fan 101 and the dust collection assembly 102. The cleaning base station 200 includes a dust collection fan 201 and a dust collection container 202. The dust collection fan 201 is disposed corresponding to the dust collection container 202, and the dust collection container 202 is configured to cooperate with the dust collection assembly 102. The controller 300 is configured to: upon detecting that the cleaning device 100 and the cleaning base station 200 are properly connected, acquire a first dust collection command signal. In response to the first dust collection command signal, the cleaning fan 101 is controlled to blow air towards the cleaning filter 103 to blow the dirt on the cleaning filter 103 into the dust collection assembly 102, and then the dust collection fan 201 is controlled to extract the dirt in the dust collection assembly 102 into the dust collection container 202.

[0061] It should be noted that the controller 300 described above can be a controller corresponding to the cleaning device 100 and the cleaning base station 200 respectively, so as to control the operation of their respective components. For example, the controller 300 of the cleaning device 100 can control the operation of the cleaning fan 101, and the cleaning base station 200 can control the operation of the dust collection fan 201. When the cleaning device 100 and the cleaning base station 200 are connected, they can transmit data to their respective controllers, thereby executing the automatic dust collection method provided in the first aspect of the present invention; or, the controller 300 is only the controller of one of the cleaning device 100 and the cleaning base station 200, and the other device is equipped with a wireless communication module or a wired communication module, so that centralized control of the two can be achieved through a single controller, thereby executing the automatic dust collection method provided in the first aspect of the present invention.
