[0062] See also Figure 1-Figure 2 , Figure 2 This is a schematic diagram of the structure of the cleaning host 100 provided in an embodiment of the present application from a front perspective. Figure 2 The schematic diagram of the structure of the cleaning main body 100 provided in the embodiment of the present application from the back view. The back of the cleaning main body 100 is the bottom surface facing the ground when the cleaning main body 100 is supported on the ground, and the front of the cleaning main body is the top surface that can be observed when the cleaning main body 100 is supported on the ground.

[0063] The embodiment of the present application provides a cleaning host 100, which can be any one of a sweeping robot, a mopping robot, a floor washing robot, or a sweeping and mopping robot.

[0064] The cleaning host 100 provided in the embodiment of the present application includes multiple working modes, at least one of which is a vacuuming mode. In some other examples, the working mode of the cleaning host 100 can also be at least one of a mopping mode, a washing mode or a dust pushing mode.

[0065] Regarding the dust suction mode, it can be understood that the dust on the ground is sucked into the dust box 104 of the cleaning host 100 by vacuum suction.

[0066] In some examples, the cleaning host 100 further includes a roller brush 105 , which rotates to sweep and vacuum the floor debris into a dust box 104 of the cleaning host 100 .

[0067] Specifically, the cleaning host 100 provided in the embodiment of the present application includes a body 101 , a filter 102 and a dust suction fan 103 .

[0068] The body 101 may be understood as a supporting frame of the cleaning host 100 , and components of the cleaning host 100 , such as the filter 102 , the dust suction fan 103 and the dust box 104 , are supported on the body 101 .

[0069] See also Figure 1 The machine body 101 is provided with a dust outlet 1012 and an air outlet 1013; see Figure 2 A dust suction port 1011 is also provided on the body 101. When the cleaning host 100 provided in the embodiment of the present application is in dust suction mode, the dust suction fan 103 in the cleaning host 100 is started, and the air in the environment can be sucked in through the dust suction port 1011, and the air flow passes through the dust box 104, the filter 102 and the dust suction fan 103 and is discharged through the air outlet 1013, and the garbage on the ground enters the dust box 104 in the cleaning host 100 through the dust suction port 1011 along with the air flow.

[0070] In one example, see Figure 1 The dust outlet 1012 and the air outlet 1013 are both arranged on the outer circumferential side of the body 101. With the moving direction of the cleaning host 100 as the front, the dust outlet 1012 and the air outlet 1013 are close to the rear side of the body 101, and the dust outlet 1012 and the air outlet 1013 are arranged at intervals along the circumferential direction of the body 101.

[0071] When the cleaning host 100 is in the dust collection mode, the filter 102 filters the dust, and the clean air is discharged from the air outlet 1013 to avoid dust pollution. However, after a period of use, the dust will gradually block the pores of the filter 102, resulting in increased resistance of the filter 102, affecting the dust collection efficiency of the whole machine.

[0072] Based on the above problems, the cleaning host 100 provided in the embodiment of the present application also includes a cleaning mode. When the cleaning host 100 runs the cleaning mode, the filter 102 can be cleaned to reduce the clogging of the mesh of the filter 102.

[0073] Specifically, when the cleaning host 100 is in the cleaning mode, the air outlet 1013 receives the active airflow, and the active airflow passes through the filter 102 and is finally discharged from the dust outlet 1012. Dust and other debris on the filter 102 are removed by backblowing to reduce the blockage of the mesh of the filter 102 and achieve cleaning of the filter 102.

[0074] In some examples, when the cleaning host 100 is in the cleaning mode, a storage device is provided at the air outlet 1013 , and the storage device is used to store dust and other debris blown off the filter 102 .

[0075] Regarding active airflow, it can be understood that the active airflow is the airflow blown into the cleaning host 100 from the air outlet 1013. For example, in some examples, when the cleaning host 100 is in the cleaning mode, an airflow generating device is provided at the air outlet 1013, and the airflow generating device can be a fan assembly, and when the airflow generating device is started, airflow can be blown into the air outlet 1013.

[0076] Regarding the dust exhaust port 1012 on the cleaning host 100, the dust exhaust port 1012 is connected to the dust box 104 through an air duct. Air is exhausted at the dust exhaust port 1012 to extract the garbage in the dust box 104 on the cleaning host 100, thereby cleaning the garbage in the dust box 104.

[0077] In some examples, the cleaning host 100 cooperates with a cleaning base station, which is a docking station for the cleaning host 100 and is used to perform preset operations for the cleaning host 100, such as charging the cleaning host 100, recycling garbage in the dust box 104 of the cleaning host 100, replenishing water for the cleaning host 100, cleaning the rag on the cleaning host 100, and other operations.

[0078] In some examples, the cleaning host 100 can walk autonomously, without direct human control and operation when performing cleaning work, and also has functions such as path planning, automatic obstacle avoidance, human-computer interaction, and return charging. The bottom of the cleaning host 100 is provided with a driving structure such as a driving wheel and / or a crawler to achieve automatic walking.

[0079] In some examples, the cleaning host 100 is highly intelligent and can minimize user operations. After the cleaning host 100 has been working for a period of time, when the cleaning host 100 determines that the garbage in the dust box 104 needs to be recovered and / or the rag needs to be cleaned, the cleaning host 100 can automatically return to the cleaning base station to recover the garbage in the dust box 104 and / or clean the rag at the cleaning base station.

[0080] Regarding the garbage collection in the dust box 104 by the cleaning base station, specifically, when the cleaning host 100 is located in the cleaning base station, the dust exhaust port 1012 on the cleaning host 100 is connected with the dust collection port 2011 on the cleaning base station. When the cleaning host 100 receives an instruction to collect the garbage in the dust box, the dust collection fan 202 on the cleaning base station is started, and the garbage in the dust box 104 is sucked into the dust bin 2013 in the cleaning base station under the action of negative pressure.

[0081] In the embodiment of the present application, the cleaning mode is run by the cleaning host so that the active airflow can pass through the filter 102, and the dust and other debris on the filter 102 are removed by backblowing to reduce the blockage of the mesh of the filter 102 and achieve the cleaning of the filter 102.

[0082] Regarding the active airflow, in one embodiment, the active airflow is supplied intermittently and / or the flow rate of the active airflow is adjustable.

[0083] In one example, the active airflow is intermittently supplied, that is, active airflow intermittently flows in from the air outlet 1013. For example, in one scenario, when the filter 102 of the cleaning host 100 needs to be dusted, active airflow is blown into the air outlet 1013 every t seconds, where the value range of t can be greater than 0 and less than 5 seconds.

[0084] In one example, when the active airflow is intermittently supplied, the time of each air supply may be different and / or the time of each interval may be different.

[0085] When the air flows through the filter 102, the filter 102 will be elastically deformed to a certain extent under the blowing of the air flow, and the filter 102 will be reset when the air flow is stopped from flowing into the air outlet 1013. By setting the active air flow to be intermittently supplied, the filter 102 will vibrate due to the repeated switching between deformation and reset, thereby achieving the effect of vibration dust removal, which is conducive to better cleaning of the filter 102.

[0086] In one example, the flow rate of the active airflow is adjustable, that is, when the active airflow blows into the air outlet 1013, the flow rate of the active airflow is not a fixed value, but a variable value.

[0087] For example, in one scenario, the active airflow can be set to repeatedly increase and then decrease, or, in other scenarios, the active airflow is blown into the air outlet 1013 at a flow rate V1 and the blowing time is t1 seconds, and then the active airflow is blown into the air outlet 1013 at a flow rate V2 and the blowing time is t2 seconds. By setting the active airflow to repeatedly switch between the flow rate V1 and the flow rate V2, where V1>V2>0, the flow rate of the active airflow can be adjusted.

[0088] When the air flow rate is relatively large, the elastic deformation of the filter 102 is large. When the air flow rate is relatively small, the elastic deformation of the filter 102 is small. The filter 102 continuously switches between large deformation and small deformation, so that the filter 102 can produce a vibration effect, thereby achieving the effect of vibration dust removal, which is conducive to better cleaning of the filter 102.

[0089] In one example, the active airflow is intermittently supplied and the flow rate of the active airflow is adjustable. The intermittent supply of the active airflow means that the active airflow flows in intermittently from the air outlet 1013, and when the active airflow blows into the air outlet 1013, the flow rate of the active airflow is adjustable, thereby achieving the intermittent supply of the active airflow and the adjustable flow rate of the active airflow.

[0090] For example, in one scenario, when the filter 102 needs to be cleaned, the active airflow is controlled to blow into the air outlet 1013 every time interval t. When the active airflow blows into the air outlet 1013, the flow rate of the active airflow can be controlled to change in the form of a sine wave or a triangular wave.

[0091] In this example, when active airflow is blown into the air outlet 1013, since the flow rate of the active airflow is adjustable, the filter 102 continuously switches between large deformation and small deformation, so that the filter 102 can produce a vibration effect; when the active airflow is supplied intermittently, since the filter 102 switches between deformation and resetting, the filter 102 can produce a vibration effect, thereby achieving the effect of vibration dust removal, which is conducive to better cleaning of the filter 102.

[0092] See also Figure 3 , is a schematic diagram of the internal structure of the cleaning host 100 provided in an embodiment of the present application.

[0093] In one embodiment, the rotation direction of the dust suction fan 103 is controlled differently in the dust suction mode and the cleaning mode; in other embodiments, the dust suction fan 103 may be controlled not to start in the cleaning mode, and the cleaning host 100 actively blows the impeller of the dust suction fan 103 to rotate when the cleaning mode is running. The following mainly uses the example of controlling the rotation direction of the dust suction fan 103 differently in the dust suction mode and the cleaning mode as an example for explanation.

[0094] The dust suction fan 103 includes a dust suction fan first end 1031 and a dust suction fan second end 1032, see Figure 3 , showing the second end 1032 of the dust suction fan. When the cleaning host 100 is in the dust suction mode, the dust suction fan 103 is started, the first end 1031 of the dust suction fan is the suction end, and the second end 1032 of the dust suction fan is the exhaust end. At this time, the direction of the impeller in the dust suction fan 103 can be considered to be the positive direction, and the air in the environment is sucked in through the dust suction port 1011, and the airflow flows to the first end 1031 of the dust suction fan after passing through the dust box 104 and the filter box 102, and then flows to the air outlet 1013 after being discharged from the second end 1032 of the dust suction fan. When the cleaning host 100 runs the cleaning mode, the active airflow is blown into the air outlet 1013. At this time, the dust suction fan 103 can be controlled to rotate in the opposite direction. At this time, the second end 1032 of the dust suction fan is the suction end, and the first end 1031 of the dust suction fan is the exhaust end. The airflow flowing in from the air outlet 1013 flows to the second end 1032 of the dust suction fan, and is discharged from the first end 1031 of the dust suction fan and then flows to the dust exhaust port 1012 after passing through the filter 102 and the dust box 104.

[0095] In one example, see Figure 3A host second air duct 1014 and a host third air duct 1015 are also provided in the body 101 , the filter 102 and the dust suction fan 103 are connected through the host second air duct 1014 , and the dust suction fan 103 and the air outlet 1013 are connected through the host third air duct 1015 .

[0096] In one example, see Figure 3 A fourth air duct 1016 of the main machine is also provided in the machine body 101 , and the fourth air duct 1016 of the main machine is connected to the dust box 104 and the dust exhaust port 1012 .

[0097] In the embodiment of the present application, by controlling the rotation direction of the dust suction fan 103 to be different in the dust suction mode and the cleaning mode, it is helpful to reduce the resistance of the active airflow when it flows to the dust suction fan 103.

[0098] See also Figure 4-Figure 8 , Figure 4 This is a schematic diagram of the internal structure of the cleaning host 100 provided in an embodiment of the present application. Figure 4 Schematically shows the interior of the dust box 104; Figure 5 for Figure 4 A partial enlarged view of the middle A; Figure 6 A cross-sectional schematic diagram of a cleaning host 100 provided in an embodiment of the present application; Figure 7 This is a schematic diagram of the internal structure of the cleaning host 100 provided in an embodiment of the present application. Figure 7 The valve structure 106 is not shown; Figure 8 A schematic diagram of airflow flowing in a cleaning host 100 provided in an embodiment of the present application.

[0099] In one embodiment, see Figure 7 The dust box 104 is provided with a dust box inlet 10411, the body 101 is provided with a host first air duct, the host first air duct connects the dust suction port 1011 and the dust box inlet 10411, and a valve structure 106 is provided on the host first air duct or at the dust box inlet 10411.

[0100] In one example, see Figure 3 The dust box 104 includes a dust box top plate 1043, and the dust box top plate 1043 is configured to be detachable. Figure 4 , is a schematic diagram of the dust box top plate 1043 being disassembled.

[0101] In this embodiment, the valve structure 106 can be arranged on the first air duct of the host, or the valve structure 106 can be arranged on the dust box inlet 10411. In this case, the valve structure 106 is installed on the dust box 104. Figure 4 and Figure 6 , illustrating that the valve structure 106 is installed on the dust box 104.

[0102] When the cleaning host 100 is in the vacuum mode, the valve structure 106 is in an open state, and external air enters through the dust box inlet 10411 and flows to the dust box 104 along the first air duct of the host through the valve structure 106; when the cleaning host 100 is in the cleaning mode, the valve structure 106 is in a closed state to prevent the active airflow flowing into the dust box 104 through the air outlet 1013 from flowing to the dust suction port 1011 through the first air duct of the host, thereby preventing dust and other debris from being discharged to the external environment through the air outlet 1013 when the filter 102 is being removed.

[0103] In one example, the valve structure 106 is a solenoid valve. When the cleaning host 100 is in a vacuuming mode, the controller of the cleaning host 100 controls the valve structure 106 to be in an open state; when the cleaning host 100 is in a cleaning mode, the controller of the cleaning host 100 controls the valve structure 106 to be in a closed state.

[0104] In one example, the valve structure 106 is a one-way valve, and the conducting direction of the valve structure 106 is from the first air duct of the host to the filter 102 .

[0105] When the cleaning host 100 is in the vacuum mode, the vacuum fan 103 is started, and air enters through the vacuum port 1011 and flows to the first air duct of the host. Under the action of the airflow flowing in the first air duct of the host, the valve structure 106 opens; when the cleaning host 100 is in the cleaning mode, the valve structure 106 prevents the active airflow flowing into the dust box 104 through the air outlet 1013 from flowing to the vacuum port 1011 through the first air duct of the host.

[0106] In this example, by setting the valve structure 106 as a one-way valve, the valve structure 106 can be opened under the action of the airflow flowing in the first air duct of the main unit, and the one-way valve 106 is closed under the action of the active airflow, thereby preventing the garbage and dust in the dust box 104 from flowing back to the dust suction port 1011 due to the active airflow. At the same time, setting the valve structure 106 as a one-way valve can simplify the control of the cleaning main unit 100.

[0107] In one embodiment, see Figure 5 , the valve structure 106 is rotatably connected to the dust box 104, see Figure 6 The surface of the dust box 104 on which the valve structure 106 is installed is an inclined surface, and the valve structure 106 is in a state of closing the dust box inlet 10411 under the action of gravity.

[0108] The side plate of the dust box 104 for the valve structure 106 is a dust box mounting plate 1041, see Figure 4-Figure 6The valve structure 106 is installed on the inner side of the dust box mounting plate 1041. In one example, the entire dust box mounting plate 1041 is tilted, that is, the entire inner side of the dust box mounting plate 1041 is an inclined surface; in other examples, a partial area of ​​the inner side of the dust box mounting plate 1041 is an inclined surface, a dust box inlet 10411 is arranged on the inclined surface and the valve structure 106 is supported on the inclined surface.

[0109] From top to bottom, the inclined surface is inclined toward the inner side of the dust box 104. For example, the entire inner side of the dust box mounting plate 1041 is an inclined surface. Figure 6 , Figure 6 The dust box inner cavity 1042 is schematically shown in the figure. From top to bottom, the dust box mounting plate 1041 is inclined toward the dust box inner cavity 1042 so that the valve structure 106 is supported on the inner side of the dust box mounting plate 1041.

[0110] When the cleaning host 100 is in the dust collection mode, the dust collection fan 103 is started, and air enters through the dust collection port 1011 and flows to the first air duct of the host. Under the action of the airflow flowing in the first air duct of the host, the valve structure 106 is pushed to rotate relative to the dust box 104 so that the valve structure 106 opens the dust box inlet 10411; when the cleaning host 100 is in the cleaning mode, the valve structure 106 is in a state of closing the dust box inlet 10411 under the action of gravity, and the active airflow flowing into the dust box 104 through the air outlet 1013 will blow toward the valve structure 106, and under the action of air pressure, the valve structure 106 will fit tightly against the inner side of the dust box mounting plate 1041.

[0111] In one example, see Figure 5 The valve structure 106 is plate-shaped as a whole, and the valve structure 106 can cover the dust box inlet 10411.

[0112] For a specific example, see Figure 5 The valve structure 106 includes a main body 1061 and a connecting ear 1062. The two connecting ears 1062 are connected to the main body 1061. The area of ​​the main body 1061 is larger than the area of ​​the dust box inlet 10411, that is, the main body 1061 can cover the dust box inlet 10411; see Figure 5 A mounting portion 107 is provided on the inner side of the dust box mounting plate 1041 , and two connecting ears 1062 are respectively inserted into the corresponding mounting portions 107 and each connecting ear 1062 is rotatably connected to the corresponding mounting portion 107 , thereby realizing the rotatable connection between the valve structure 106 and the dust box 104 .

[0113] In one example, the two connecting ears 1062 are relatively arranged on the left and right sides of the main body 1061, and the two connecting ears 1062 are close to the top of the main body 1061; in other examples, see Figure 5The two connecting ears 1062 are disposed at the top of the main body 1061 , and the two connecting ears 1062 are disposed far away from each other.

[0114] In one example, the two connecting ears 1062 are integrally formed with the main body 1061 .

[0115] In one example, see Figure 5 , the mounting portion 107 is in an arc shape, a C shape, or a U shape, and both ends of the mounting portion 107 are connected to the inner side surface of the dust box mounting plate 1041; in other examples, the mounting portion 107 is a hook structure.

[0116] In one example, the mounting portion 107 is detachably connected to the dust box mounting plate 1041 ; in other examples, the mounting portion 107 is connected to the dust box mounting plate 1041 by welding or bonding or is an integrally formed structure.

[0117] In this embodiment, by providing the valve structure 106 to close the dust box inlet 10411 under the action of gravity, the valve structure 106 can be simplified and the processing and manufacturing of the valve structure 106 can be facilitated.

[0118] In one embodiment, see Figure 7 The filter 102 is installed on the dust box 104, and the filter 102 is arranged opposite to the dust box inlet 10411.

[0119] When the cleaning host 100 is in the dust collection mode, the air entering from the dust collection port 1011 can enter the dust box 104 through the dust box inlet 10411, and the air in the dust box 104 is discharged from the air outlet 1013 through the filter 102 and the dust collection fan 103. In this embodiment, the filter 102 is arranged opposite to the dust box inlet 10411, so that the air entering the dust box 104 through the dust box inlet 10411 can flow out of the dust box 104 through the filter 102.

[0120] In one example, see Figure 7 , schematically shows the fourth air duct 1016 of the main unit, which connects the dust box 104 and the dust outlet 1012. A valve body is provided at a position on the dust box 104 that is connected to the fourth air duct 1016 of the main unit, or a valve body is provided on the fourth air duct 1016 of the main unit, and when the cleaning main unit 100 is in the dust suction mode, the valve body is in a closed state; when the cleaning main unit 100 is in the cleaning mode, the valve body is in an open state.

[0121] In one example, see Figure 7 The dust box inlet 10411 and the filter 102 are arranged opposite to each other and are respectively located on the sides of the dust box 104 in the length direction. One end of the dust box 104 in the length direction is connected to the fourth air duct 1016 of the main unit.

[0122] See also Figure 8 , illustrates the flow of active airflow in the cleaning host 100 when the active airflow is blown into the air outlet 1013 in the cleaning host 100. The active airflow passes through the third air duct 1015 of the host, the dust suction fan 103, the second air duct 1014 of the host, and the filter 102 to flow to the dust box 104, and then passes through the dust box 104 and is discharged to the dust outlet 1012 through the fourth air duct 1016 of the host.

[0123] In one embodiment, the cleaning host 100 further includes a detection device for detecting whether the filter 102 is dirty or clogged. The cleaning host 100 sends a filter cleaning instruction in response to the dirty or clogged condition of the filter 102 detected by the detection device. The filter cleaning instruction is used to control the occurrence of active airflow.

[0124] That is, the detection device detects the dirtiness and blockage of the filter 102, and feeds back the detection result to the controller of the cleaning host 100. The controller judges the information sent by the detection device. When it is determined that the dirtiness and blockage of the filter 102 meets the cleaning conditions, the controller sends a filter cleaning instruction.

[0125] In one example, the detection device is a wind resistance detection device, which evaluates the blockage of the filter 102 by detecting the pressure difference before and after the air passes through the filter 102. When the filter 102 is dirty and blocked, the resistance of the air passing through the filter 102 will increase, resulting in an increase in the pressure difference.

[0126] In one example, the detection device detects the working current of the dust suction fan 103. When the filter 102 is severely clogged, the working current of the dust suction fan 103 increases. When the working current of the dust suction fan 103 is greater than a preset threshold (for example, 10%, 20% or 30% higher than the standard working current, etc.), the fan is considered to be clogged.

[0127] In this embodiment, a detection device for detecting whether the filter screen 102 is dirty or clogged is provided so that the filter screen 102 can be cleaned in time when the filter screen 102 is dirty or clogged.

[0128] See also Fig. 9 , Fig. 9 A schematic diagram of a portion of the structure of a cleaning base station provided in an embodiment of the present application.

[0129] In one embodiment, the active airflow is generated by the dust collection fan 202 in the cleaning base station when it is in operation.

[0130] In this example, see Fig. 9 The cleaning base station is provided with an exhaust port 2012, which is used to connect with the air outlet 1013 on the cleaning host 100. By starting the dust collecting fan 202, an active airflow can be provided to the cleaning host 100.

[0131] It should be noted here that starting the dust collecting fan 202 can be based on the dust collection demand, for example, when the garbage in the dust box 104 is saturated, or after a cleaning is completed, the dust collecting fan 202 is started when the cleaning base station collects the garbage in the dust box 104; or starting the dust collecting fan 202 can also be based on the cleaning demand of the filter 102.

[0132] In some examples, after the cleaning host 100 has been working for a period of time, when the cleaning host 100 determines that the filter 102 needs to be cleaned, the cleaning host 100 can automatically return to the cleaning base station to clean the filter 102 at the cleaning base station.

[0133] In one example, the air outlet of the dust collecting fan 202 is always connected to the exhaust port 2012; in other examples, the cleaning base station is also provided with an external exhaust port, which can be switched to the air outlet of the dust collecting fan 202 being connected to the exhaust port 2012 or to the air outlet of the dust collecting fan 202 being connected to the external exhaust port by controlling the switching mechanism in the cleaning base station. The following mainly takes the example that the air outlet of the dust collecting fan 202 is always connected to the exhaust port 2012 as an example for explanation.

[0134] The dust collecting fan 202 on the cleaning base station is started, and the dust collecting fan 202 sucks the air in the dust bin 2013. Under the action of negative pressure, the garbage in the dust box 104 is sucked into the dust bin 2013 in the cleaning base station along with the air flow. The airflow discharged by the dust collecting fan 202 flows through the exhaust port 2012 to the air outlet 1013 of the cleaning host 100, and then flows through the dust fan 103 and the filter 102 to the dust box 104. When the airflow passes through the filter 102, it has the effect of back-blowing and dust removal on the filter 102, and the dust and other debris blown off the filter 102 flows to the dust box 104, and can finally be collected in the dust bin 2013.

[0135] In one example, when the cleaning base station receives an instruction from the cleaning host 100 to recycle garbage in the dust box, the cleaning base station controls the dust collecting fan 202 to start, and controls the dust collecting fan 202 to run at a constant speed.

[0136] In one example, when the cleaning base station receives a filter cleaning instruction issued by the cleaning host 100, the cleaning base station controls the dust collecting fan 202 to start, and controls the dust collecting fan 202 to run at a constant speed; in other examples, when the cleaning base station receives a filter cleaning instruction issued by the cleaning host 100, the cleaning base station controls the dust collecting fan 202 to start, and controls the dust collecting fan 202 to work intermittently and / or change speed. The intermittent operation of the dust collecting fan 202 can realize intermittent supply of active airflow, and the variable speed operation of the dust collecting fan 202 can realize adjustable flow rate of the active airflow.

[0137] Regarding the intermittent operation and / or variable speed operation of the dust collecting fan 202, it means that the dust collecting fan 202 can be controlled to work intermittently, and the speed of the dust collecting fan 202 can be kept at a certain value when it rotates; or, the dust collecting fan 202 can be controlled to work at a variable speed; or, the dust collecting fan 202 can be controlled to work intermittently and the speed of the dust collecting fan 202 can be controlled to change when it rotates.

[0138] The cleaning base station receives the command sent by the cleaning host 100. In one example, the cleaning host 100 only sends the command to collect the garbage in the dust box; in other examples, the cleaning base station sends both the command to collect the garbage in the dust box and the command to clean the filter. When the cleaning host 100 only sends the command to collect the garbage in the dust box, the dust collecting fan 202 is started, and the filter 102 can also be cleaned.

[0139] Here, it should be noted that when the cleaning host 100 only sends an instruction to recycle the garbage in the dust box, the dust collection fan 202 is started, and the garbage in the dust box 104 can be recycled into the dust bin 2013 of the cleaning base station. At the same time, the filter 102 can be cleaned, which is equivalent to utilizing the airflow generated when the cleaning base station collects dust and outputting it into the cleaning host 100. On the one hand, it can clean the filter 102, and on the other hand, it can also be regarded as a secondary utilization of the airflow that was originally discharged directly to the outside, thereby achieving the purpose of energy saving.

[0140] In one example, the cleaning host 100 sends a filter cleaning instruction in response to the dirty or clogged condition of the filter 102 detected by the detection device.

[0141] In one example, the cleaning host 100 sends an instruction to recycle the garbage in the dust box in response to the amount of garbage in the dust box 104 detected by the garbage detection device; in other examples, the cleaning host 100 responds to the cleaning host 100 returning to the cleaning base station detected by the position detection device and sends an instruction to recycle the garbage in the dust box.

[0142] In one example, when the cleaning base station receives an instruction to recycle garbage in the dust box and an instruction to clean the filter at the same time, the dust collecting fan 202 is controlled to start, and the dust collecting fan 202 runs at a constant speed.

[0143] In one example, when the cleaning base station receives an instruction to recycle garbage in the dust box and an instruction to clean the filter at the same time, the dust collecting fan 202 is started, and the dust collecting fan 202 works intermittently and / or at a variable speed.

[0144] In one example, when the cleaning base station receives an instruction to recycle garbage in the dust box and a filter cleaning instruction at the same time, the dust collecting fan 202 is controlled to start, and the dust collecting fan 202 is controlled to run at a constant speed for T1 time, and then the dust collecting fan 202 is controlled to work intermittently and / or at a variable speed for T2 time.

[0145] In one example, when the cleaning base station receives an instruction to recycle garbage in the dust box and a filter cleaning instruction at the same time, the dust collecting fan 202 is controlled to start, and the dust collecting fan 202 is controlled to work intermittently and / or operate at a variable speed for T1 time, and then the dust collecting fan 202 is controlled to run at a constant speed for T2 time.

[0146] In one example, when it is determined that the filter 102 is cleaned, the cleaning host 100 sends a filter cleaning completion instruction to the cleaning base station; when it is determined that the garbage in the dust box 104 is cleaned, the cleaning host 100 sends a dust box garbage cleaning completion instruction to the cleaning base station.

[0147] In one example, when the cleaning base station simultaneously receives an instruction to recycle garbage in the dust box and an instruction to clean the filter, the dust collecting fan 202 is controlled to start, and the dust collecting fan 202 runs at a constant speed; when the cleaning base station first receives an instruction to complete cleaning of garbage in the dust box, the dust collecting fan 202 is controlled to work intermittently and / or at a variable speed, and when the cleaning base station first receives an instruction to complete cleaning of the filter, the dust collecting fan 202 is controlled to continue running at a constant speed.

[0148] In one example, when the cleaning base station simultaneously receives an instruction to recycle garbage in the dust box and an instruction to clean the filter, the dust collecting fan 202 is controlled to start, and the dust collecting fan 202 is controlled to continue to work intermittently and / or work at a variable speed; when the cleaning base station first receives an instruction to complete cleaning of garbage in the dust box, the dust collecting fan 202 continues to be controlled to work intermittently and / or work at a variable speed, and when the cleaning base station first receives an instruction to complete cleaning of the filter, the dust collecting fan 202 is controlled to run at a constant speed.

[0149] As described above, in one example, an external exhaust port is also provided on the cleaning base station, and the air outlet of the dust collecting fan 202 can be switched to be connected to the exhaust port 2012 or the air outlet of the dust collecting fan 202 can be switched to be connected to the external exhaust port by controlling the switching mechanism in the cleaning base station.

[0150] In this example, when the cleaning base station receives an instruction to collect the garbage in the dust box, the dust collecting fan 202 is started, and the switching mechanism is controlled so that the air outlet of the dust collecting fan 202 is connected to the external exhaust port, and the air discharged from the air outlet of the dust collecting fan 202 is discharged to the external environment through the external exhaust port. When the cleaning base station receives an instruction to clean the filter, the dust collecting fan 202 is controlled to start, and the switching mechanism is controlled so that the air outlet of the dust collecting fan 202 is connected to the exhaust port 2012.

[0151] In one example, the filter cleaning instruction has a higher priority than the instruction for collecting the garbage in the dust box, that is, when the cleaning base station receives the instruction for collecting the garbage in the dust box and the filter cleaning instruction at the same time, the dust collecting fan 202 is controlled to start, and the switching mechanism is controlled so that the air outlet of the dust collecting fan 202 is connected to the exhaust port 2012. When the cleaning base station receives the instruction for collecting the garbage in the dust box while executing the filter cleaning instruction, the air outlet of the dust collecting fan 202 is still controlled to be connected to the exhaust port 2012. When the cleaning base station receives the filter cleaning instruction while executing the instruction for collecting the garbage in the dust box, the switching mechanism is controlled so that the air outlet of the dust collecting fan 202 is switched from being connected to the external exhaust port to being connected to the air outlet of the dust collecting fan 202.

[0152] In one embodiment, a body sealing structure is provided on the body 101, an intermediate flow channel is formed in the body sealing structure, one end of the body sealing structure is connected to the air outlet 1013, and the other end of the body sealing structure is used to be connected to the exhaust port 2012 of the cleaning base station. When the cleaning host 100 is located in the cleaning base station, the air outlet 1013 and the exhaust port 2012 are connected through the body sealing structure.

[0153] In an example, the body sealing structure includes a body connecting portion and an elastic deformation portion, wherein the body connecting portion is disposed at one end of the elastic deformation portion, and the body connecting portion is connected to the body 101 .

[0154] In one example, when the cleaning host 100 is located in the cleaning base station, the elastic deformation part abuts against the cavity wall of the cleaning base station accommodating cavity 2017, and the elastic deformation part undergoes elastic deformation; in other examples, when the cleaning host 100 is located in the cleaning base station, the elastic deformation part is inserted into the exhaust port 2012 and sealed with the exhaust port 2012.

[0155] In one example, the body connection portion is connected to one end of the third air duct 1015 of the host, and the elastic deformation portion is inserted into the air outlet 1013 and sealed with the air outlet 1013 .

[0156] In this embodiment, a body sealing structure is provided on the body 101 so that the airflow discharged from the air outlet 2012 flows to the air outlet 1013 .

[0157] See also Figure 10-13 , Fig.10 A schematic diagram of a partial structure of a cleaning base station provided in an embodiment of the present application from a front perspective; Fig.11 A schematic diagram of a partial structure of a cleaning base station provided in an embodiment of the present application from a rear side perspective; Fig.12 Another schematic diagram of a partial structure of a cleaning base station provided in an embodiment of the present application (dust bin door 2014 is not shown); Fig.13This is a schematic diagram of the cleaning host 100 provided in an embodiment of the present application when located at a cleaning base station.

[0158] The cleaning base station provided in this embodiment cooperates with the cleaning host 100. The cleaning base station is a docking station for the cleaning host 100 and is used to perform preset operations for the cleaning host 100, such as charging the cleaning host 100, collecting dust in the dust box 104 of the cleaning host 100, replenishing water for the cleaning host 100, washing the rag of the cleaning host 100, etc. In the embodiment of the present application, the cleaning base station can also clean the filter 102 on the cleaning host 100.

[0159] Specifically, see Fig.10 The cleaning base station provided in this embodiment includes a station body 201. The station body 201 can be understood as a supporting frame of the cleaning base station. Components of the cleaning base station, such as a dust collecting fan 202, are supported on the station body 201.

[0160] See also Fig.10 A dust collecting port 2011 and an air exhaust port 2012 are provided on the station body 201 , wherein the dust collecting port 2011 is used to connect with the dust exhaust port 1012 of the cleaning host 100 , and the air exhaust port 2012 is used to connect with the air outlet 1013 on the cleaning host 100 .

[0161] In one example, see Fig.10 A accommodating cavity 2017 is formed on the station body 201. When the cleaning host 100 returns to the cleaning base station, the cleaning host 100 is located in the accommodating cavity 2017, and the dust collection port 2011 of the cleaning base station is connected with the dust exhaust port 1012 of the cleaning host 100, and the air outlet 1013 of the cleaning host 100 is connected with the air exhaust port 2012 on the cleaning base station.

[0162] In one embodiment, see Fig.12 A dust collecting port 2011 and an air exhaust port 2012 are provided on the vertical cavity wall 20171 of the accommodating cavity 2017. The dust collecting port 2011 and the air exhaust port 2012 are arranged at intervals along the circumferential direction of the vertical cavity wall 20171.

[0163] In one example, see Fig.10 A dust bin 2013 is formed on the station body 201. The dust bin 2013 is located above the accommodating chamber 2017. The dust collecting port 2011 is connected to the dust bin 2013 through an air duct. Fig.11 , showing the second air duct 2016 of the station body, the second air duct 2016 of the station body connects the dust collecting port 2011 and the dust bin 2013. The dust collecting fan 202 includes an air suction end and an air outlet end, the air suction end of the dust collecting fan 202 is connected to the dust bin 2013, and the air outlet end of the dust collecting fan 202 is connected to the exhaust port 2012 through an air duct.

[0164] In one example, a dust bin door 2014 is provided on the dust bin 2013, see Fig.10 , indicating the dust bin door 2014. Open the dust bin door 2014 to place a dust bag in the dust bin 2013 or take out a dust bag. Fig.12 , which is a schematic diagram of the dust bin door 2014 after it is opened.

[0165] The cleaning base station provided in this embodiment can provide active airflow to the cleaning host 100. When the cleaning host 100 is located in the cleaning base station, the dust collecting fan 202 is started, and the airflow can flow through the dust box 104, the dust outlet 1012, the dust collecting outlet 2011, the dust bin 2013, the dust collecting fan 202, the air outlet 2012, the air outlet 1013, the dust suction fan 103, the filter 102 and then flow to the dust box 104. When the airflow passes through the filter 102, it has the effect of back-blowing and dust removal on the filter 102, and the dust and other debris blown off the filter 102 flow to the dust box 104, and finally can be collected in the dust bin 2013.

[0166] The cleaning base station provided in this embodiment can receive instructions sent by the cleaning host 100. When the cleaning base station receives the filter cleaning instruction and the dust box garbage collection instruction sent by the cleaning host 100, the cleaning base station controls the dust collecting fan 202 to work.

[0167] The cleaning base station provided in this embodiment is provided with an exhaust port 2012 for docking with the air outlet 1013 on the cleaning host 100, so that when the dust collecting fan 202 is working, it can provide active airflow to the cleaning host 100, and can clean the filter 102 to reduce the clogging of the mesh of the filter 102.

[0168] In one embodiment, when the cleaning base station receives an instruction to recycle garbage in the dust box, the dust collecting fan 202 is controlled to start, and the dust collecting fan 202 is controlled to run at a constant speed.

[0169] In one embodiment, when the cleaning base station receives a filter cleaning instruction, the dust collecting fan 202 is controlled to start, and the dust collecting fan 202 is controlled to run at a constant speed.

[0170] In one embodiment, when the cleaning base station receives a filter cleaning instruction, it controls the dust collecting fan 202 to start and stop intermittently and / or controls the speed of the dust collecting fan 202 to be adjustable, so as to facilitate cleaning of the filter 102 in the cleaning host 100.

[0171] For example, in one example, when the cleaning base station receives a filter cleaning instruction, the dust collecting fan 202 is controlled to start, and the dust collecting fan 202 is controlled to work intermittently, and the speed of the dust collecting fan 202 is a certain value. The intermittent operation of the dust collecting fan 202 can realize intermittent supply of active airflow, so that the filter 102 can vibrate, thereby achieving the effect of vibration dust removal, which is conducive to better cleaning of the filter 102.

[0172] For example, in one example, when the cleaning base station receives a filter cleaning instruction, the dust collecting fan 202 is controlled to start and the dust collecting fan 202 is controlled to work at a variable speed. By the variable speed operation of the dust collecting fan 202, the flow rate of the active airflow can be adjusted, so that the filter 102 can vibrate, thereby achieving the effect of vibration dust removal, which is conducive to better cleaning of the filter 102.

[0173] For example, in one example, when the cleaning base station receives a filter cleaning instruction, the dust collecting fan 202 is controlled to start, the dust collecting fan 202 is controlled to work intermittently, and the dust collecting fan 202 is controlled to work at a variable speed when the dust collecting fan 202 rotates. The intermittent operation of the dust collecting fan 202 realizes intermittent supply of active airflow; the variable speed operation of the dust collecting fan 202 realizes adjustable flow rate of the active airflow.

[0174] Regarding the variable speed operation of the dust collecting fan 202, for example, in one scenario, the speed of the dust collecting fan 202 can be set to repeatedly increase first and then decrease, or, in other scenarios, the speed of the dust collecting fan 202 is first controlled to be V1 and run for t1 seconds, and then the speed of the dust collecting fan 202 is controlled to be V2 and run for t2 seconds. By setting the speed of the dust collecting fan 202 to repeatedly switch between speed V1 and speed V2, where V1>V2>0, the flow rate of the active airflow can be adjusted.

[0175] That is, in this embodiment, by setting the dust collecting fan 202 to start and stop intermittently and / or the speed of the dust collecting fan 202 to be adjustable, the filter 102 can generate vibration, thereby achieving the effect of vibration dust removal, which is conducive to better cleaning of the filter 102.

[0176] In one embodiment, the station body 201 is provided with a first station body air duct 2015, which is connected to the dust collecting fan 202 and the exhaust port 2012; a switching mechanism is provided on the first station body air duct 2015, and the station body 201 is also provided with a switching air duct, which is connected to the switching mechanism, and the switching mechanism is adjusted to allow the airflow to be discharged through the exhaust port 2012 or discharged to the external environment through the switching air duct; in other embodiments, the first station body air duct 2015 is always connected to the dust collecting fan 202 and the exhaust port 2012, that is, the switching air duct and the switching mechanism are not provided on the station body 201. The following mainly takes the setting of the switching mechanism on the first station body air duct 2015 as an example for explanation.

[0177] In this embodiment, when the cleaning base station receives an instruction to collect garbage in the dust box, the dust collecting fan 202 is started, and the switching mechanism is controlled so that the air outlet of the dust collecting fan 202 is connected to the switching air duct, and the air discharged from the air outlet of the dust collecting fan 202 is discharged to the external environment through the switching air duct. When the cleaning base station receives an instruction to clean the filter, the dust collecting fan 202 is controlled to start, and the switching mechanism is controlled so that the air outlet of the dust collecting fan 202 is connected to the exhaust port 2012.

[0178] In one example, the filter cleaning instruction has a higher priority than the instruction for collecting garbage in the dust box, that is, when the cleaning base station receives the instruction for collecting garbage in the dust box and the filter cleaning instruction at the same time, the dust collecting fan 202 is controlled to start, and the switching mechanism is controlled so that the air outlet of the dust collecting fan 202 is connected to the exhaust port 2012. When the cleaning base station receives the instruction for collecting garbage in the dust box while executing the filter cleaning instruction, the air outlet of the dust collecting fan 202 is still controlled to be connected to the exhaust port 2012. When the cleaning base station receives the filter cleaning instruction while executing the instruction for collecting garbage in the dust box, the switching mechanism is controlled so that the air outlet of the dust collecting fan 202 is connected to the switching air duct so that the air outlet of the dust collecting fan 202 is connected to the exhaust port 2012.

[0179] In one example, the switching mechanism is a three-way valve.

[0180] In this embodiment, the switching mechanism is adjusted to allow the air flow to be discharged through the exhaust port 2012 or to be discharged to the external environment by switching the air duct, so that when the filter 102 does not need to be cleaned, the air discharged from the dust collection fan 202 can be discharged to the external environment in time.

[0181] In one embodiment, a station body sealing structure 203 is provided on the station body 201, and an intermediate flow channel is formed in the station body sealing structure 203. One end of the station body sealing structure 203 is connected to the exhaust port 2012, and the other end of the station body sealing structure 203 is used to be connected to the outlet 1013 of the cleaning host 100.

[0182] In this embodiment, a station body sealing structure 203 is provided on the station body 201 so that the air exhausted from the exhaust port 2012 flows to the air outlet 1013 , thereby providing active airflow for the cleaning host 100 .

[0183] In one embodiment, the station body sealing structure 203 includes a connecting portion and a deforming portion, wherein the connecting portion is disposed at one end of the deforming portion, the connecting portion is connected to the station body 201, and the deforming portion can be elastically deformed. When the cleaning host 100 is located in the cleaning base station, the deforming portion abuts against the outer circumferential surface of the cleaning host 100, and the deforming portion is elastically deformed.

[0184] In one example, the connecting portion is connected to one end of the first air duct 2015 of the station body, and the deforming portion passes through the exhaust port 2012 and is sealed with the exhaust port 2012 .

[0185] In this embodiment, a body sealing structure is provided on the body 101 so that the airflow discharged from the air outlet 2012 flows to the air outlet 1013 .

[0186] An embodiment of the present application provides a cleaning system, including the cleaning host 100 provided in any of the above embodiments and the cleaning base station provided in any of the above embodiments.

[0187] The cleaning host 100 includes a body 101, a filter 102 and a dust suction fan 103. The body 101 is provided with a dust suction port 1011, a dust exhaust port 1012 and an air outlet 1013. The filter 102 and the dust suction fan 103 are arranged on the body 101, and the dust suction fan 103 is respectively connected to the dust suction port 1011, the dust exhaust port 1012 and the air outlet 1013.

[0188] The cleaning base station includes a station body 201 and a dust collecting fan 202. The station body 201 is provided with a dust collecting port 2011 and an exhaust port 2012. The dust collecting fan 202 is arranged on the station body 201. The dust collecting fan 202 is connected to the dust collecting port 2011 and the exhaust port 2012 respectively. The dust collecting port 2011 is used to connect with the dust exhaust port 1012 of the cleaning host 100, and the exhaust port 2012 is used to connect with the air outlet 1013 on the cleaning host 100.

[0189] When the cleaning host 100 is outside the cleaning base station, the cleaning host can run the dust collection mode, the dust collection fan 103 works, and the airflow enters the dust box 104 of the cleaning host 100 from the dust collection port 1011, and is discharged from the air outlet 1013 after passing through the filter 102 and the dust collection fan 103. The garbage on the ground flows into the dust box 104 through the dust collection port 1011 along with the airflow.

[0190] When the cleaning host 100 is located in the cleaning base station, the cleaning host 100 can run the cleaning mode. When the cleaning host 100 sends a filter cleaning instruction to the cleaning base station, the dust collecting fan 202 is started, and the airflow flows through the dust box 104, the dust outlet 1012, the dust collecting outlet 2011, the dust bin 2013, the dust collecting fan 202, the exhaust port 2012, the air outlet 1013, the dust collecting fan 103, the filter 102 and then flows to the dust box 104. When the airflow passes through the filter 102, it has the effect of back-blowing and dust removal on the filter 102, and the dust and other debris blown off the filter 102 flow to the dust box 104 and can finally be collected in the dust bin 2013.

[0191] In the cleaning system provided in the embodiment of the present application, the cleaning base station can clean the filter 102 of the cleaning host 100 to reduce the clogging of the mesh of the filter 102.

[0192] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
