However, the existing dust removal method requires the dust collection station to provide dust removal power, and the dust collection station needs to be equipped with a motor, a dust removal channel or components connected to the motor, etc., which makes the internal structure of the dust collection station complicated and increases the production cost of the dust collection station.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0069] The present invention provides a vacuum cleaner system 100, combined with Figures 1 to 4 As shown, the vacuum cleaner system 100 includes a dust collecting station 1, a vacuum cleaner device 2, an air duct switching structure 4, a detection device (not shown in the drawings) and a control device 1000. The dust collecting station 1 can be connected to the vacuum cleaner device 2, and the dust collecting station 1 provides a placement position for the vacuum cleaner device 2, and the vacuum cleaner device 2 can be cleaned by the dust collecting station 1; the vacuum cleaner device 2 includes a device body 21, and a dust cup assembly 22 and a suction device 3 arranged on the device body 21, and the air inlet end of the suction device 3 is connected to the air outlet end of the dust cup assembly 22; the air duct switching structure 4 is movably arranged between the air outlet end of the dust cup assembly 22 and the air inlet end of the suction device 3 The air duct switching structure 4 is connected to the passage and has at least a first working state in which the suction device 3 and the dust collecting station 1 are connected; the detection device is used to detect the position state of the air duct switching structure 4; the control device 1000 is electrically connected to the detection device and the air duct switching structure 4; when the dust collecting station 1 and the vacuum cleaner device 2 are docked, the control device 1000 can control the air duct switching structure 4 to enter the first working state according to the position state of the air duct switching structure 4 detected by the detection device, so that the suction device 3 is connected to the dust collecting station 1, and a negative pressure is formed in the dust collecting station 1 through the suction device 3 to suck the dirt in the dust cup assembly 22 of the vacuum cleaner device 2, so that the vacuum cleaner device 2 enters the sewage discharge state.

[0070] In this embodiment, when the vacuum cleaner device 2 is connected to the dust collecting station 1 or after the connection, the position state of the air duct switching structure 4 can be detected by the detection device, so that the control device 1000 can control the air duct switching structure 4 to move according to the position state of the air duct switching structure 4 obtained by the detection device, so that the air duct switching structure 4 can move to make the suction device 3 and the dust collecting station 1 conductive, and then, the suction device 3 of the vacuum cleaner device 2 provides suction power, so that negative pressure is formed in the dust collecting station 1, and the dust collecting station 1 is connected to the dust cup assembly 22. Under the action of the negative pressure in the dust collecting station 1, the dirt in the dust cup assembly 22 can enter the dust collecting station 1, and the dust cup assembly 22 can be self-cleaned. Therefore, there is no need to set a power device in the dust collecting station 1 to provide cleaning power for the self-cleaning of the dust cup assembly 22, the structure of the dust collecting station 1 can be simpler, the cost is lower, and the dust collecting station 1 can be easier to maintain.

[0071] It can be understood that the vacuum cleaner device 2 also has a cleaning function, and the suction device 3 of the vacuum cleaner device 2 can be directly or indirectly connected to the dust cup assembly 22. Figures 5 to 7 As shown, the air duct switching structure 4 also has a second working state that conducts the dust cup assembly 22 and the suction device 3. The control device 1000 can control the air duct switching structure 4 to enter the second working state according to the position state of the air duct switching structure 4 detected by the detection device, so as to enter the dust collection state. Specifically, when the vacuum cleaner device 2 needs to perform cleaning work, for example, the user issues a cleaning command (turns on the cleaning button or issues a voice cleaning command, etc.), the detection device will first detect the position state of the air duct switching structure 4 to ensure that when the air duct switching structure 4 is in the second working state, the suction device 3 is started to work to avoid the inaccurate position of the air duct switching structure 4, which may cause misoperation. When the air duct switching structure 4 enters the second working state, the suction device 3 is connected with the dust cup assembly 22, and a dust suction port is also provided on one side of the vacuum cleaner device 2, which is connected with the dust cup assembly 22. When the suction device 3 is working, a negative pressure is formed in the dust cup assembly 22, and external dirt is sucked into the dust cup assembly 22 from the dust suction port. The clean airflow can enter the suction device 3 after being discharged from the dust cup assembly 22, thereby realizing the cleaning work of the vacuum cleaner device 2.

[0072] This embodiment monitors the working state of the air duct switching structure 4 through the detection device, so that the control device 1000 can better control the operation of the air duct switching structure 4, and the air duct switching structure 4 can more accurately enter the corresponding working mode, with intelligent adjustment operation, which makes the user operation more worry-free and provides a better user experience.

[0073] The vacuum cleaner device 2 can be configured as a vacuum cleaner, preferably a handheld vacuum cleaner. Figure 2 and Figure 5As shown, the device body 21 of the vacuum cleaner device 2 includes a shell, a handle structure formed on one side of the shell, and a receiving cavity formed above the handle structure. The suction device 3 is arranged in the receiving cavity, and a vent hole is arranged on the cavity wall of the receiving cavity. The air outlet end of the suction device 3 is connected to the vent hole, and the airflow discharged by the suction device 3 can be discharged from the vacuum cleaner device 2 through the vent hole. The dust cup assembly 22 is arranged roughly in a cylindrical shape, and the handle structure is connected to one side of the dust cup assembly 22. It should be noted that when the vacuum cleaner device 2 is working normally, the axial direction of the dust cup assembly 22 is arranged in the up-down direction, the suction device 3 is arranged near the upper part of the dust cup assembly 22 and is connected to the upper part of the dust cup assembly 22, and a dust suction port is arranged on the peripheral side of the dust cup assembly 22, and the dust suction port and the handle structure are respectively located on two opposite sides of the dust cup assembly 22, for example, the handle structure is arranged on the left side of the dust cup assembly 22, and the dust suction port is located on the right side of the dust cup assembly 22, so that when the user holds the handle structure, the dust suction port can be better oriented to the surface to be cleaned. The description of the orientation in the present invention can be referred to as above unless otherwise specified.

[0074] Furthermore, if Figure 5 As shown in , the dust cup assembly 22 includes a dust cup cavity 221, a first filter 222, a second filter 223 and a third filter 224. The dust cup cavity 221 is cylindrical and hollow inside. The first filter 222 is arranged on the inner side of the dust cup cavity 221 and is cylindrical. Preferably, the first filter 222 is arranged as a filter cylinder and is coaxially arranged with the dust cup cavity 221. The second filter 223 is arranged on the inner side of the first filter 222 and is connected to the air outlet side of the first filter 222. Preferably, the second filter 223 is arranged as a multi-cone filter, and the air inlet side of the multi-cone filter is connected to the air outlet side of the first filter 222; the third filter 224 is arranged outside the dust cup cavity 221 and is connected to the air outlet end of the second filter 223. Preferably, the third filter 224 is arranged as a hepa, and the hepa is arranged in a circular ring shape, the inner ring side of the hepa is the air inlet side, and the outer ring side of the hepa is the air outlet side. The air outlet side of the multi-cone filter is connected to the inner ring side of the HEPA, and the dust outlet of the multi-cone filter is connected to the dust cup cavity 221. Figure 5 As shown in the figure, the dotted arrow indicates the direction of air flow. When the vacuum cleaner device 2 is performing cleaning work, the suction airflow can enter the dust cup cavity 221 through the dust suction port, enter the multi-cone filter after the first filtration through the first filter 222, and pass through the multi-cone filter for a second filtration. The filtered dust falls into the dust cup cavity 221, and the filtered airflow flows toward the inner ring side of the HEPA, enters the suction device 3 through the air duct switching structure 4 after the third filtration through the HEPA, and is finally discharged from the vacuum cleaner device 2, forming an airflow cycle to realize the cleaning operation of the vacuum cleaner device 2.

[0075] Preferably, in the first working state, that is, when the vacuum cleaner equipment 2 is connected to the dust collecting station 1 and the suction device 3 is connected to the dust collecting station 1, the air duct switching structure 4 blocks the connecting passage between the dust cup assembly 22 and the suction device 3 to prevent part of the airflow from entering the dust cup assembly 22, causing the dust port to suck in dirt while the dust cup assembly 22 is discharging dirt, causing the discharge operation to last too long, affecting the discharge efficiency; and it can avoid the airflow diversion formed by the suction device 3, and the suction force formed in the dust collecting station 1 is greater, thereby improving the discharge efficiency.

[0076] In the second working state, that is, the suction device 3 of the vacuum cleaner device 2 is connected to the dust cup assembly 22, the air duct switching structure 4 blocks the connecting passage between the dust collecting station 1 and the suction device 3, so that when the vacuum cleaner device 2 is vacuuming, the connecting passage between the dust collecting station 1 and the suction device 3 is blocked, to prevent the dirt in the dust cup assembly 22 from leaking into the connecting passage between the dust collecting station 1 and the suction device 3 to cause pipeline blockage or to prevent the dirt from leaking out to cause secondary pollution; it can also avoid the separation of airflow, and can ensure that the dust suction force is stronger, the cleaning effect of the vacuum cleaner device 2 is better, and the cleaning efficiency is higher.

[0077] The control device 1000 can control the air duct switching structure 4 to switch between the first working state and the second working state according to the position state of the air duct switching structure 4 detected by the detection device, so that the vacuum cleaner device 2 can enter the sewage discharge state and the cleaning state respectively. For example, when the vacuum cleaner device 2 is docked with the dust collecting station 1, the detection device can first detect the position state of the air duct switching structure 4. If the air duct switching structure 4 is in the first working state, the state of the air duct switching structure 4 is kept unchanged. At this time, the suction device 3 and the dust collecting station 1 are in the conducting state, so that the suction device 3 can be turned on to enter the sewage discharge state; if the detection device detects that the air duct switching structure 4 is in the second working state, the working state of the air duct switching structure 4 can be switched by the control device 1000 first, so that the air duct switching structure 4 enters the first working state, and then the sewage discharge operation is performed. Accordingly, it can be ensured that before the vacuum cleaner device 2 enters the sewage discharge state, the air duct switching structure 4 is in the first working state to ensure that the suction device 3 and the dust collecting chamber are in conduction, so as to better realize the sewage discharge of the dust cup assembly 22, and intelligently adjust the position of the air duct switching structure 4, so that the vacuum cleaner system 100 works more intelligently.

[0078] Preferably, combined Figure 3 and Figure 6As shown in the figure, a first channel 5 connecting the air outlet of the dust cup assembly 22 and the air inlet of the suction device 3 is formed in the device body 21, and a second channel connecting the suction device 3 and the dust collecting station 1 is formed. The air outlet of the dust cup assembly 22 specifically refers to the air outlet of the third filter 224, and the first channel 5 is a passage between the air outlet of the third filter 224 and the suction device 3. The first channel 5 is arranged in an arc shape to match the shape of the dust cup cavity 221. The first channel 5 is arranged on the outer ring side of the third filter 224 and has a first opening 51 connected to the air outlet end of the third filter 224. A second opening 52 is also opened on the first channel 5. The second opening 52 is a docking port connected to the dust collecting station 1. In the flow direction of the dust extraction airflow (that is, the direction of the airflow when the vacuum cleaner device 2 performs cleaning work), the second opening 52 is arranged closer to the suction device 3 than the first opening 51. A first channel 5 connecting the suction device 3 and the dust cup assembly 22 is formed between the suction device 3 and the first opening 51, and a second channel connecting the suction device 3 and the dust collecting station 1 is formed between the suction device 3 and the second opening 52. It can be understood that by blocking the passage between the first opening 51 and the second opening 52 of the first channel 5, the communication passage between the suction device 3 and the dust cup assembly 22 can be blocked, and by blocking the second opening 52, the communication passage between the suction device 3 and the dust collection station 1 can be blocked, so as to realize the switching of the two working states of the vacuum cleaner device 2. At this time, the detection device can monitor the working state of the air duct switching structure 4 by detecting the conduction and blocking states of the first channel 5 and the second channel.

[0079] Specifically, for the air duct switching structure 4, combined with Figure 3 and Figure 6 As shown, the air duct switching structure 4 includes a first blocking part 41 and a second blocking part 42, a connecting rod structure 43 connected to the first blocking part 41 and the second blocking part 42, and a trigger member 44. The first blocking part 41 and the second blocking part 42 are both rotatably arranged in the device body 21. When the connecting rod structure 43 is moved by an external force, the first blocking part 41 and the second blocking part 42 can be driven to move. The passage between the suction device 3 and the dust cup assembly 22 can be opened and blocked through the first blocking part 41, and the passage between the suction device 3 and the dust collecting station 1 can be opened and blocked through the second blocking part 42. The trigger member 44 is movably arranged on the vacuum cleaner device 2 or the dust collecting station 1 to apply a force to the connecting rod structure 43.

[0080] Specifically, the detection device can be used to detect the position state of the trigger member 44. When the trigger member 44 is in the first trigger position, the trigger member 44 and the connecting rod structure 43 are in a state of being away from each other, and the air duct switching structure 4 is in the second working state. When the trigger member 44 is in the second trigger position, the trigger member 44 acts on the connecting rod structure 43 to drive the connecting rod structure 43 to move, thereby prompting the first blocking portion 41 and the second blocking portion 42 to move, so that the air duct switching structure 4 is in the first working state. The position state of the trigger member 44 is obtained by the detection device, so that the working state of the air duct switching structure 4 can be known. The control device 1000 can be electrically connected to the trigger member 44. The control device 1000 controls the movement of the trigger member 44 according to the position state detected by the detection device, and realizes the automatic switching of the state of the air duct switching structure 4 by controlling and monitoring the position of the trigger member 44.

[0081] Among them, Figure 6 As shown in , a through hole 53 is formed on the channel section between the first opening 51 and the second opening 52. When in the first working state, the first blocking portion 41 blocks the through hole 53, and the second blocking portion 42 opens the second opening 52; when in the second working state, the first blocking portion 41 opens the through hole 53, and the second blocking portion 42 blocks the second opening 52. The first blocking portion 41 has a first blocking surface, which has a first conducting position for conducting the first channel 5 and a first blocking position for blocking the first channel 5, and the through hole 53 can be opened and blocked by the first blocking surface; the second blocking portion 42 has a second blocking surface, which has a second conducting position for conducting the second channel and a second blocking position for blocking the second channel, and the second opening 52 can be opened and blocked by the second blocking surface. Preferably, the detection device can also be set corresponding to the through hole 53 and / or the second opening 52, and directly detects at the blocking position of the two channels, so that the detection result is more accurate and reliable.

[0082] Among them, the vacuum cleaner system 100 also includes a sensing part arranged on the air duct switching structure 4, and the detection device includes a detector. When the sensing part is in the detection area of ​​the detector, the air duct switching structure 4 is in a first working state; when the sensing part is outside the detection area of ​​the detector, the air duct switching structure 4 is in a second working state, so that the working state of the air duct switching structure 4 can be accurately identified, so that the vacuum cleaner device 2 can better enter the corresponding working state to work.

[0083] In one embodiment, the sensing part is arranged on at least one of the first blocking part 41 and the second blocking part 42, and the detector is arranged corresponding to the first blocking position, and / or the second blocking position, and / or the first conduction position, and / or the second conduction position. For example, when the sensing part is arranged on the first blocking part 41, and the detector is arranged corresponding to the first blocking position, when the first blocking part 41 blocks the through hole 53, that is, the sensing part moves to the first blocking position together with the first blocking part 41, the detector at the first blocking position can detect the sensing part, thereby confirming that the air duct switching structure 4 is in the first working state; when the first blocking part 41 leaves the first blocking position, the detector cannot detect the sensing part, thereby confirming that the air duct switching structure 4 enters the second working state. In this way, the sensing part and the detector at the first blocking part and / or the second blocking part 42, and / or the first blocking position, and / or the second blocking position, and / or the first conduction position, and / or the second conduction position can be implemented with reference to the above embodiment, and the specific number of settings can be arranged according to actual needs, and no specific limitation is made here.

[0084] Preferably, the detection device can be set as a position sensor, and the sensing part can be set as a sensing block. When the sensing block is in the sensing area of ​​the position sensor, the position sensor can issue a first instruction, and when the sensing block is outside the sensing area of ​​the position sensor, the position sensor will issue a second instruction. The control device 1000 can control the air duct switching structure 4 to work according to different instructions issued by the position sensor, so that the vacuum cleaner device 2 can enter different working states.

[0085] In one embodiment, the first blocking portion 41 and the second blocking portion 42 are both connected to the same rotating shaft 431, and the connecting rod structure 43 is connected to the rotating shaft 431. When the connecting rod structure 43 is moved by an external force, the first blocking portion 41 and the second blocking portion 42 can be driven to rotate. The first blocking portion 41 and the second blocking portion 42 are arranged at an angle, that is, the first blocking portion 41 and the second blocking portion 42 are not on the same plane, and the relative position is fixed. The detection device can confirm the state of the air duct switching structure 4 by obtaining the rotation angle of the rotating shaft 431. For example, two sensing parts are provided on the air duct switching structure 4, and the two sensing parts are provided on the rotating shaft 431 and are arranged at intervals along the circumference of the rotating shaft 431. The detection device may include a detector, which may be provided on a rotating groove in which the equipment body 21 and the rotating shaft 431 are socketed. When one of the sensing parts is in the detection area of ​​the detector, that is, one sensing part is opposite to the detector, the air duct switching structure 4 is in the first working state; when the other sensing part is in the detection area of ​​the detector, that is, the rotating shaft 431 is rotated so that the other sensing part is opposite to the detector, the air duct switching structure 4 is in the second working state, so as to realize the monitoring of the switching of the two working states of the air duct switching structure 4.

[0086] In another embodiment, a sensing part may be provided on the air duct switching structure 4, and the detection device includes two detectors. When the sensing part is in the detection area of ​​one of the detectors, the air duct switching structure 4 is in the first working state; when the sensing part is in the detection area of ​​the other detector, the air duct switching structure 4 is in the second working state. For example, a detector may be provided at the second opening 52 and the through hole 53, respectively, and the first blocking part 41 and the second blocking part 42 are integrally provided shielding plates, the sensing part is provided on the shielding plate, and the second opening 52 and the through hole 53 are blocked by a shielding plate, respectively, so that when the detector located at the second opening 52 detects the sensing part, it indicates that the air duct switching structure 4 is in the second working state, and when the detector located at the through hole 53 detects the sensing part, it indicates that the air duct switching structure 4 is in the first working state.

[0087] The first blocking portion 41 is configured as a first blocking plate 411, and the second blocking portion 42 is configured as a second blocking plate 421. As for the connecting rod structure 43, the connecting rod structure 43 can be used to drive the first blocking plate 411 and the second blocking plate 421 to move when the connecting rod structure 43 itself moves under the action of an external force. The connecting rod structure 43 includes a connecting component 432 and a transmission component 433. The connecting component 432 connects the transmission component 433, the first blocking portion 41 and the second blocking portion 42. When the transmission component 433 moves under the action of an external force, the connecting component 432 can be driven to move, thereby driving the first blocking portion 41 and the second blocking portion 42 to move, so that the air duct switching structure 4 can achieve the switching of two working states.

[0088] And preferably, combined with Figure 4 , Figure 7 and Figure 8As shown, the movement of the connecting rod structure 43 can drive the rotating shaft 431 connected to the first blocking plate 411 and the second blocking plate 421 to rotate, so that the first blocking plate 411 and the second blocking plate 421 can rotate together. The transmission component 433 includes a first transmission shaft 4331 and a first connecting rod 4332 arranged on one side of the first transmission shaft 4331, and the connecting component 432 includes a second connecting rod 4321 and a third connecting rod 4322 hinged at one end, the other end of the second connecting rod 4321 is hinged to the first connecting rod 4332, and the other end of the third connecting rod 4322 is connected to the rotating shaft 431, and the first connecting rod 4332 and the third connecting rod 4322 are parallel. The first transmission shaft 4331, the first connecting rod 4332, the second connecting rod 4321, the third connecting rod 4322 and the rotating shaft 431 form a double rocker mechanism, so that when the first transmission shaft 4331 rotates, the rotating shaft 431 can be driven to rotate, and the double rocker mechanism and the first blocking part 41 and the second blocking part 42 can be staggered in the up and down directions to occupy less space in the radial direction of the rotating shaft 431, thereby occupying less space in the vacuum cleaner device 2, so that the volume of the vacuum cleaner device 2 can be smaller.

[0089] The detection device may be arranged corresponding to the rotating shaft 431, and / or the first connecting rod 4332, and / or the second connecting rod 4321, and / or the third connecting rod 4322, and / or the first transmission shaft 4331 to detect the rotation angle or position of the rotating shaft 431, and / or the first connecting rod 4332, and / or the second connecting rod 4321, and / or the third connecting rod 4322, and / or the first transmission shaft 4331, so as to determine the position of the first blocking plate 411 and / or the second blocking plate 421, thereby determining the working state of the air duct switching structure 4, so as to better confirm the working state of the vacuum cleaner device 2. The specific setting method can refer to the above embodiment, which will not be described in detail here.

[0090] In another embodiment of the air duct switching structure 4, combined with Fig. 9 and Fig.10As shown, the vacuum cleaner device 2 is formed with an annular air duct 240, and the suction side of the suction device 3 is connected to the annular air duct 240. The annular air duct 240 is arranged in an annular shape to have a first side wall 225 and a second side wall 226 arranged opposite to each other in the radial direction. The dust collecting station 1 is connected to the first side wall 225 to form a first connecting port 225a, and the dust cup cavity 221 is connected to the second side wall 226 to form a second connecting port 226a. The air duct switching structure 4 includes a blocking portion 45, and the blocking portion 45 is movably arranged in a first direction between the first connecting port 225a and the second connecting port 226a to have a first position for blocking the first connecting port 225a and a second position for blocking the second connecting port 226a. When in the first position, the suction side of the suction device 3 is connected to the dust cup cavity 221 via the annular air duct 240, and when in the second position, the suction side of the suction device 3 is connected to the dust collecting station 1 via the annular air duct 240.

[0091] like Fig.11 As shown in FIG. 2 , the first side wall 225 is the outer side wall of the annular air duct 240 , and the second side wall 226 is the inner side wall of the annular air duct 240 .

[0092] The first direction is a radial direction of the annular air duct 240 , and the orthographic projection of the first communication opening 225 a in the first direction at least partially overlaps with the orthographic projection of the second communication opening 226 a in the first direction, so that the blocking portion 45 can perform reciprocating translational motion along the first direction.

[0093] When the first direction is a radial direction of the annular air duct 240 as described above, the suction side of the suction device 3 is connected to a side of the annular air duct 240 away from the first connecting port 225a and / or the second connecting port 226a along the first direction.

[0094] The vacuum cleaner device 2 also has an outlet duct 230 connecting the annular air duct 240 and the dust cup chamber 221, and the outlet duct 230 is extended along the first direction. The duct switching structure 4 also includes a mounting portion 46, which is connected to the blocking portion 45, and the blocking portion 45 can be movably mounted in the annular air duct 240, and the mounting portion 46 can be movably mounted in the outlet duct 230.

[0095] The mounting portion 46 is elastically mounted in the air outlet duct 230 via an elastic member 48 . When driven by an external force, the blocking portion 45 is moved to the second position. When the external force is removed, the blocking portion 45 is driven by the elastic member 48 to return to the first position.

[0096] The outer diameter of the blocking portion 45 is larger than the diameter of the first connecting port 225a and the diameter of the second connecting port 226a, the outer diameter of the mounting portion 46 is smaller than the inner diameter of the air outlet duct 230, and at least the outer diameter of the connection between the mounting portion 46 and the blocking portion 45 is smaller than the diameter of the second connecting port 226a.

[0097] The mounting portion 46 is provided with a connecting flow channel 47 , wherein when in a first position, the connecting flow channel 47 connects the annular air channel 240 and the air outlet air channel 230 ; when in a second position, the connecting flow channel 47 connects the air outlet air channel 230 .

[0098] The connecting flow channel 47 forms an air inlet and an air outlet on the outer wall of the mounting portion 46 , and the air inlet and / or the air outlet are arranged around the circumference of the mounting portion 46 .

[0099] The third filter 224 is arranged downstream of the dust cup chamber 221 and upstream of the air outlet duct 230. The annular air duct 240 is arranged around the third filter 224 and the air outlet duct 230.

[0100] Among them, the sensing part can be set on the blocking part 45, and the detector can be set at the first connecting port 225a and / or the second connecting port 226a. Through the detection cooperation between the detector and the sensing part, the position of the blocking part 45 can be better known to obtain the working status of the air duct switching structure 4.

[0101] The present invention also provides a control device 1000 for a vacuum cleaner system, Fig.13 As shown, the control device 1000 includes a memory 1005, a processor 1001, and a control program of the vacuum cleaner system 100 stored in the memory 1005 and executable on the processor 1001, and the control program of the vacuum cleaner system 100 is configured to implement the steps of the control method of the vacuum cleaner system 100. It should be noted that the control device 1000 may include: a processor 1001, such as a CPU, a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard), and a button. The optional user interface 1003 may also include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a WI-FI interface). The memory 1005 may be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. The memory 1005 may optionally be a storage device independent of the aforementioned processor 1001 .

[0102] Those skilled in the art will understand that Fig.13 The structure of the control device 1000 shown in the figure does not constitute a limitation of the control device 1000, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0103] like Fig.13 As shown, the memory 1005 as a computer storage medium may include an operating system, a network communication module, a user interface module, and a control program of the vacuum cleaner system 100 .

[0104] exist Fig.13 In the control device 1000 shown, the control program of the vacuum cleaner system 100 stored in the memory 1005 is called by the processor 1001, and the following operations are performed:

[0105] In response to an instruction that the dust collecting station 1 and the vacuum cleaner device 2 are docked in place, obtaining a position state of the air duct switching structure 4 detected by a detection device;

[0106] The air duct switching structure 4 is controlled to move according to the position state, so that the air duct switching structure 4 can connect the dust collecting station 1 and the suction device 3.

[0107] Further, in response to the instruction that the dust collection station 1 and the vacuum cleaner device 2 are docked in place, before obtaining the position state of the air duct switching structure 4 detected by the detection device, the processor 1001 calls the control program of the vacuum cleaner system 100 stored in the memory 1005, and also performs the following operations:

[0108] Determine whether the dust collection station 1 and the vacuum cleaner device 2 are properly docked;

[0109] If the dust collection station 1 and the vacuum cleaner device 2 are docked, a first instruction is issued;

[0110] If the dust collection station 1 and the vacuum cleaner device 2 are not docked, a second instruction is issued.

[0111] Further, when the vacuum cleaner device 2 further includes a dust cup assembly 22, and the air duct switching structure 4 has a first working state of connecting the dust collection station 1 and the suction device 3, and has a second working state of connecting the suction device 3 and the dust cup assembly 22, the processor 1001 calls the control program of the vacuum cleaner system 100 stored in the memory 1005, and further performs the following operations:

[0112] If the detection device detects that the air duct switching structure 4 is in the first working state, the state of the air duct switching structure 4 is kept unchanged;

[0113] If the detection device detects that the air duct switching structure 4 is in the second working state, the air duct switching structure 4 is controlled to switch from the second working state to the first working state.

[0114] Combining the above hardware facilities and Fig.12As shown, the present invention further provides a control method for a vacuum cleaner system. When the vacuum cleaner system 100 includes a dust collection station 1, a vacuum cleaner device 2, a detection device, and an air duct switching structure 4, and the vacuum cleaner device 2 includes a suction device 3, the control method of the vacuum cleaner system 100 specifically includes the following steps:

[0115] S100, in response to an instruction that the dust collection station 1 and the vacuum cleaner device 2 are docked, obtaining a position state of the air duct switching structure 4 detected by a detection device;

[0116] S200 , controlling the movement of the air duct switching structure 4 according to the position state, so that the air duct switching structure 4 can conduct the dust collecting station 1 and the suction device 3 .

[0117] Specifically, in response to the instruction that the dust collecting station 1 and the vacuum cleaner device 2 are docked in place, it refers to the instruction issued by the vacuum cleaner device 2 and / or the dust collecting station 1 when or after the dust collecting station 1 and the vacuum cleaner device 2 are docked. For example, when the vacuum cleaner device 2 is placed on the dust collecting station 1, the dust collecting station 1 can sense that the vacuum cleaner device 2 is placed thereon through a position sensor or a weight sensor, and then the dust collecting station 1 issues an instruction that the vacuum cleaner device 2 is placed in place. Alternatively, after the vacuum cleaner device 2 is placed on the dust collecting station 1, the vacuum cleaner device 2 or the dust collecting station 1 can emit a prompt sound or a prompt light to indicate that the vacuum cleaner device 2 and the dust collecting station 1 are docked in place.

[0118] Then, the position state of the air duct switching structure 4 can be detected by the detection device, and the movement of the air duct switching structure 4 can be adjusted according to the detection result of the detection device to ensure that the air duct switching structure 4 is in a position to conduct the suction device 3 and the dust collecting station 1. For example, the detection device can detect the position of the trigger member 44, and / or the detection device can detect the position of the connecting rod structure 43, and / or the detection device can detect the position of the first blocking part 41 and / or the second blocking part 42, so as to know the working state of the air duct switching structure 4, and then the control device 1000 drives the trigger member 44 to move to adjust the position of the connecting rod structure 43, thereby adjusting the position of the first blocking part 41 and the second blocking part 42, so that the first blocking part 41 is in the first blocking position and the second blocking part 42 is in the second conducting position, so as to conduct the suction device 3 and the dust collecting station 1, so that negative pressure can be formed in the dust collecting station 1 for sewage discharge.

[0119] This embodiment sends a docking command after the vacuum cleaner device 2 and the dust collecting station 1 are docked, and then obtains the position state of the air duct switching structure 4 through the detection device, and then controls the air duct switching structure 4 to move through the control device 1000, so that the air duct switching structure 4 can be moved to make the suction device 3 and the dust collecting station 1 conductive, so that when the suction device 3 is working, a negative pressure can be formed in the dust collecting station 1 to perform sewage treatment. The dust collecting station 1 can automatically achieve the conduction between the dust collecting station 1 and the suction device 3 when discharging sewage, without the need for manual operation by the user, making sewage discharge more convenient, and there is no need to set a device to provide sewage discharge power in the dust collecting station 1, so that the structure of the dust collecting station 1 is also simpler.

[0120] Preferably, the vacuum cleaner device 2 further includes a dust cup assembly 22, and when the air duct switching structure 4 has a first working state of connecting the dust collecting station 1 and the suction device 3, and a second working state of connecting the suction device 3 and the dust cup assembly 22, the above step S200 specifically includes:

[0121] S210, if the detection device detects that the air duct switching structure 4 is in the first working state, the state of the air duct switching structure 4 is kept unchanged;

[0122] S220: If the detection device detects that the air duct switching structure 4 is in the second working state, the air duct switching structure 4 is controlled to switch from the second working state to the first working state.

[0123] That is, when the vacuum cleaner device 2 is docked with the dust collecting station 1, if the air duct switching structure 4 is already in the first working state, there is no need to adjust the movement of the air duct switching structure 4, and the device can directly enter the sewage discharge state to discharge the dirt in the dust cup assembly 22. When the vacuum cleaner device 2 is docked with the dust collecting station 1, if the air duct switching structure 4 is still in the second working state, it is necessary to adjust the position of the air duct switching structure 4 so that the air duct switching structure 4 enters the sewage discharge operation after being in the first working state, so as to ensure that the suction device 3 and the dust collecting station 1 are in a conductive state, so as to discharge sewage, which can better protect the vacuum cleaner system 100.

[0124] Preferably, before the above step S100, the method further includes:

[0125] S110, determining whether the dust collection station 1 and the vacuum cleaner device 2 are properly docked;

[0126] S111, if the dust collection station 1 and the vacuum cleaner device 2 are docked, a first instruction is issued;

[0127] S112: If the dust collection station 1 and the vacuum cleaner device 2 are not docked, a second instruction is issued.

[0128] After the vacuum cleaner device 2 is placed on the dust collecting station 1, the relative position of the dust collecting station 1 and the vacuum cleaner device 2 can be determined first to ensure that the vacuum cleaner device 2 and the dust collecting station 1 are properly docked before performing the sewage discharge operation to avoid sewage leakage caused by inaccurate placement of the vacuum cleaner device 2.

[0129] Specifically, when the dust collecting station 1 and the vacuum cleaner device 2 are docked in place, a first instruction is issued, wherein the first instruction can be issued by the dust collecting station 1 or the vacuum cleaner device 2. For example, the dust collecting station 1 can light up a green light to indicate that the vacuum cleaner device 2 is in place, or issue a prompt sound "placed", etc., through the first instruction to remind the user that the vacuum cleaner device 2 is in place on the dust collecting station 1. If the dust collecting station 1 and the vacuum cleaner device 2 are not docked in place, a second instruction is issued, wherein the second instruction can also be issued by the dust collecting station 1 or the vacuum cleaner device 2. For example, the dust collecting station 1 can light up a red light to indicate that the vacuum cleaner device 2 is not in place, or the dust collecting station 1 issues a "beep beep" prompt sound, etc., through the second instruction to remind the user that the vacuum cleaner device 2 is not in place on the dust collecting station 1 and should be re-placed until the dust collecting station 1 or the vacuum cleaner device 2 no longer issues the second instruction. In this way, it is ensured that the vacuum cleaner device 2 and the dust collecting station 1 are reliably aligned to avoid leakage of the dust cup assembly 22 during sewage discharge.

[0130] Preferably, a trigger 44 is further provided on the vacuum cleaner device 2, and an action part is provided on the dust collecting station 1, wherein the trigger 44 can be set as a telescopic cover plate and contact and connect with the connecting rod structure 43, and the action part can be set as an abutting protrusion on the dust collecting station 1. When the vacuum cleaner device 2 is placed on the dust collecting station 1, as the vacuum cleaner device 2 is put in, the abutting protrusion can contact and abut against the telescopic cover plate, and when the telescopic cover plate no longer moves, it indicates that the vacuum cleaner device 2 and the dust collecting station 1 are docked in place. The abutting protrusion causes the telescopic cover plate to abut against the connecting rod structure 43, and under the action of the connecting rod structure 43, the rotating shaft 431 is driven to rotate, thereby driving the first blocking part 41 and the second blocking part 42 to rotate, so that the first blocking part 41 rotates to block the through hole, and the second blocking part 42 rotates to open the second opening, so that the dust collecting station 1 and the suction device 3 are connected from the second opening. When the vacuum cleaner device 2 is put in place, the air duct switching structure 4 is just in the position of connecting the suction device 3 and the dust collecting station 1, that is, the air duct switching structure 4 can automatically be in the first working state. When the vacuum cleaner device 2 is put in place on the dust collecting station 1, the air duct switching structure 4 automatically enters the first working state, without the need for the user to adjust it multiple times, and the operation is more worry-free and intelligent. Of course, it can be re-detected and confirmed by the detection device, double confirmation, and better reliability. After it is fully confirmed that the suction device 3 is connected to the dust collecting station 1, the suction device 3 is turned on to discharge the dust cup assembly 22 on the vacuum cleaner device 2. The entire operation is safer and more reliable, and the user experience is better.
