It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0049] In addition, the terms "first", "second", etc. are used only for descriptive purposes and do not connote or imply relative importance or a quantity of the indicated elements. Thus, a feature defined with "first", "second", etc. can include one or more of the features implicitly or explicitly.

[0050] Reference within the specification of this application to "one embodiment", "an embodiment" or "the embodiment", means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. Thus, the appearances of the phrases "in one embodiment", "in an embodiment", "in some embodiments", "in other embodiments", etc. in various places throughout this specification are not necessarily all referring to the same embodiment, unless otherwise specifically stated. Furthermore, the particular features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0051] At present, household cleaning systems such as sweeping robots, vacuum cleaners and floor washing machines have gradually become standard household appliances. In order to meet various cleaning needs in the family, most families will configure multiple household cleaning systems such as sweeping robots, vacuum cleaners and floor washing machines at the same time.

[0052] In the related art, household cleaning systems such as sweeping robots, vacuum cleaners and floor washing machines are independent as a whole, and each cleaning system has a cleaning device and a base station for storing dust and debris collected by the cleaning device, which results in the need for multiple base stations in families that simultaneously configure multiple household cleaning systems, thereby causing multiple household cleaning systems to occupy a large space.

[0053] In view of the above problems, the embodiments of the present application provide a base station and a cleaning system, aiming to solve the technical problem that the cleaning system occupies a large space.

[0054] In order to illustrate the technical solutions of the present application, the following will be described in conjunction with specific drawings and embodiments.

[0055] Please refer to Figure 1 , Figure 2 and Figure 3 , the embodiments of the present application provide a base station for cooperating with a cleaning device, the base station comprising an air path switching mechanism 1 and a dust collecting pile 2, the dust collecting pile 2 having a dust collecting space 21; the air path switching mechanism 1 comprising a pipeline assembly 11, a switching assembly 12 and a sensing assembly 13.

[0056] The pipeline assembly 11 is connected with the dust collecting bin 2, the pipeline assembly 11 has a main airflow channel 1111 communicated with the dust collecting space 21 and a plurality of branch airflow channels 1121 communicated with the main airflow channel 1111, and the branch airflow channels 1121 are used for being communicated with dust outlets of the cleaning devices; the switching assembly 12 is used for opening or closing the branch airflow channels 1121; and the sensing assembly 13 is used for detecting the opening and closing states of the branch airflow channels 1121.

[0057] In the embodiment of the present application, each branch airflow channel 1121 can form an air path with the main airflow channel 1111, different air paths are communicated with different dust outlets of the cleaning devices at one end and communicated with the same dust collecting space 21 at the other end, so as to form a plurality of air paths in the air path switching mechanism 1; when the switching assembly 12 opens the branch airflow channel 1121, the air path in which the opened branch airflow channel 1121 is located is conducted; when the switching assembly 12 closes the branch airflow channel 1121, the air path in which the closed branch airflow channel 1121 is located is closed; the switching assembly 12 can open all the branch airflow channels 1121 to open all the air paths, the switching assembly 12 can close all the branch airflow channels 1121 to close all the air paths, and the switching assembly 12 can open any one or more branch airflow channels 1121 to selectively open the air paths; the air paths can be switched by changing the number and positions of the branch airflow channels 1121 opened by the switching assembly 12.

[0058] If it is needed to store the dust and sundries collected by the cleaning devices into the dust collecting space 21, the switching assembly 12 needs to open the branch airflow channel 1121 communicated with the cleaning device to be discharged, and the switching assembly 12 needs to close the remaining branch airflow channels 1121.

[0059] For example, in the embodiment shown in Figures 1 to 10 , the base station can be connected with two cleaning devices, the two cleaning devices are respectively a first cleaning device (including but not limited to the sweeping device 4a) and a second cleaning device (including but not limited to the dust collecting device 4b); the air path switching mechanism 1 has two branch airflow channels 1121, the two branch airflow channels 1121 are respectively a first branch airflow channel 1121a used for being communicated with the second cleaning device and a second branch airflow channel 1121b used for being communicated with the second cleaning device.

[0060] Please refer to Figure 1 , Figure 2 and Figure 3When the dust collecting pile 2 needs to store the dust and sundries collected by the second cleaning device, the switching assembly 12 opens the first branch air flow passage 1121a and closes the second branch air flow passage 1121b; and the opening and closing states of the first branch air flow passage 1121a and the second branch air flow passage 1121b are determined according to the detection result of the sensing assembly 13, if the first branch air flow passage 1121a is in the open state and the second branch air flow passage 1121b is in the closed state, the base station can be started; otherwise, the switching assembly 12 is continuously adjusted until the first branch air flow passage 1121a is in the open state and the second branch air flow passage 1121b is in the closed state.

[0061] Please refer to Figure 1 , Figure 5 and Figure 6 When the dust collecting pile 2 needs to store the dust and sundries collected by the second cleaning device, the switching assembly 12 closes the first branch air flow passage 1121a and opens the second branch air flow passage 1121b; and the opening and closing states of the first branch air flow passage 1121a and the second branch air flow passage 1121b are determined according to the detection result of the sensing assembly 13, if the first branch air flow passage 1121a is in the closed state and the second branch air flow passage 1121b is in the open state, the base station can be started; otherwise, the switching assembly 12 is continuously adjusted until the first branch air flow passage 1121a is in the closed state and the second branch air flow passage 1121b is in the open state.

[0062] Please refer to Figure 1 , Figure 8 and Figure 9 When the dust collecting pile 2 needs to store the dust and sundries collected by the second cleaning device and the second cleaning device, the switching assembly 12 opens the first branch air flow passage 1121a and the second branch air flow passage 1121b, and the opening and closing states of the first branch air flow passage 1121a and the second branch air flow passage 1121b are determined according to the detection result of the sensing assembly 13, if the first branch air flow passage 1121a and the second branch air flow passage 1121b are in the open state, the base station can be started; otherwise, the switching assembly 12 is continuously adjusted until the first branch air flow passage 1121a and the second branch air flow passage 1121b are in the open state.

[0063] In other embodiments, the air path switching mechanism 1 has three branch air flow passages 1121, four branch air flow passages 1121 or more branch air flow passages 1121, so that the base station can be applied to a cleaning system with three cleaning devices, four cleaning devices or more cleaning devices.

[0064] The air path switching mechanism 1 provided in the first aspect of the present application can adjust the switching assembly 12 according to the detection result of the sensing assembly 13, so that the switching assembly 12 closes or opens all branch air flow channels 1121, or so that the switching assembly 12 opens one or more branch air flow channels 1121 that are in communication with the dust outlet of the cleaning device to be cleaned. In this way, one base station can be connected to multiple cleaning devices, thereby reducing the total number of base stations in a multi-functional cleaning system, and achieving integration of the multi-functional cleaning system and reducing the total space occupied by the multi-functional cleaning system.

[0065] For reference Figure 2 In some embodiments, the sensing assembly 13 includes a plurality of sensors 132, and each sensor 132 corresponds to one branch air flow channel 1121. The sensor 132 is configured to sense the opening and closing state of the branch air flow channel 1121 and output physical information indicating the opening and closing state.

[0066] In some embodiments, the sensor 132 provides a physical signal (such as a light signal or a pattern signal) that can be intuitively perceived by a user. When the sensor 132 senses that the branch air flow channel 1121 is in an open state, the sensor 132 can react and output a physical signal. When the sensor 132 senses that the branch air flow channel 1121 is in a closed state, the sensor 132 can react and change the output physical signal, so that the user can determine the opening and closing state of the branch air flow channel 1121 corresponding to the sensor 132 according to the physical signal.

[0067] In the above embodiments, each sensor 132 corresponds to one branch air flow channel 1121, so that the sensing assembly 13 can individually detect the opening and closing state of each branch air flow channel 1121, thereby improving the detection reliability of the sensing assembly 13.

[0068] By using the above scheme, the sensing assembly 13 can quickly sense the state of the branch air flow channel 1121 following the movement of the switching assembly 12. The user can timely know the working state of the cleaning system according to the physical information provided by the sensor 132.

[0069] In some embodiments, the physical signal provided by the sensor 132 that can be intuitively perceived by a user is a light signal. The sensor 132 displays different colors of light to correspond to the state of the branch air flow channel 1121. For example, the sensor 132 displays green light to indicate that the branch air flow channel 1121 corresponding to the sensor 132 is in an open state, and the sensor 132 displays red light to indicate that the branch air flow channel 1121 corresponding to the sensor 132 is in a closed state.

[0070] In some embodiments, the physical signal provided by the sensor 132 that can be intuitively perceived by the user is a pattern signal, and the sensor 132 displays different visible information corresponding to the state of the branch airflow passage 1121. For example, the sensor 132 displays "open" to indicate that the branch airflow passage 1121 corresponding to the sensor 132 is in an open state; and the sensor 132 displays "closed" to indicate that the branch airflow passage 1121 corresponding to the sensor 132 is in a closed state.

[0071] In other embodiments, the physical signal provided by the sensor 132 that can be intuitively perceived by the user is a sound signal, and the sensor 132 outputs different sentences corresponding to the state of the branch airflow passage 1121. For example, the sensor 132 outputs the sentence "sweeping passage open" to indicate that the branch airflow passage 1121 corresponding to the sensor 132 is in communication with the dust outlet of the sweeping device and is in an open state; and the sensor 132 outputs the sentence "sweeping passage closed" to indicate that the branch airflow passage 1121 corresponding to the sensor 132 is in communication with the dust outlet of the sweeping device and is in a closed state.

[0072] Please refer to Figure 4 In some embodiments, the sensing assembly 13 further comprises a moving piece 131 connected to the switching assembly 12, and at least a part of the moving piece 131 moves to the sensing area of the sensor 132 corresponding to the closed branch airflow passage 1121 when the switching assembly 12 closes the branch airflow passage 1121.

[0074] Please refer to Figure 4 In some embodiments, each sensor 132 comprises a signal transmitter 1321 for transmitting a signal in real time and a signal receiver 1322 for receiving a signal, and the area between the signal transmitter 1321 and the signal receiver 1322 is the sensing area.

[0075] In the initial state, the branch air flow passage 1121 is in the open state, the signal receiver 1322 can receive the signal transmitted by the signal transmitter 1321, and the inductor 132 provides a physical signal, for example, the inductor 132 displays green light or the inductor 132 displays "open". When the switching assembly 12 closes the branch air flow passage 1121, the moving piece 131 moves to block the signal propagating in the corresponding inductor 132, so that the signal receiver 1322 in the inductor 132 cannot receive the signal transmitted by the signal transmitter 1321, and the inductor 132 changes the physical signal it provides, for example, the inductor 132 displays red light or the inductor 132 displays "closed".

[0076] Optionally, the signal in the above embodiment can be an infrared light signal or a laser signal.

[0077] Please refer to Figure 2 In some embodiments, the inductor 132 is an optical inductor 132, the signal transmitter 1321 and the signal receiver 1322 are arranged opposite to each other in each inductor 132, and when the switching assembly 12 closes the branch air flow passage 1121, the moving piece 131 moves to the position between the signal transmitter 1321 and the signal receiver 1322.

[0078] Optionally, in some embodiments, the inductor 132 is an optical inductor 132, each inductor 132 includes a signal transmitter 1321, a signal receiver 1322 and a reflector; the area between the signal transmitter 1321 and the reflector and the area between the signal receiver 1322 and the reflector are the sensing areas. The signal transmitter 1321 and the signal receiver 1322 are arranged on the same side of the signal reflector, the signal reflector is used to reflect the signal transmitted by the signal transmitter 1321 to the signal receiver 1322, when the switching assembly 12 closes the branch air flow passage 1121, the moving piece 131 moves to the position between the signal receiver 1322 and the signal reflector, or the moving piece 131 moves to the position between the signal transmitter 1321 and the signal reflector.

[0079] Please refer to Figures 2 to 7 In the embodiment shown, the air path switching mechanism 1 has two branch air flow passages 1121, the two branch air flow passages 1121 are respectively a first branch air flow passage 1121a and a second branch air flow passage 1121b, and the inductor assembly 13 includes two inductors 132, the two inductors 132 are respectively a first inductor 132a and a second inductor 132b, the first inductor 132a corresponds to the position of the first branch air flow passage 1121a, and the second inductor 132b corresponds to the position of the second branch air flow passage 1121b.

[0080] In the initial state, the first branch airflow passage 1121a is open, and the first sensor 132a provides a physical signal, for example, the first sensor 132a displays green light or the first sensor 132a displays "open". When the switching assembly 12 closes the first branch airflow passage 1121a (as shown in the embodiment), the moving part 131 moves to the sensing area of the first sensor 132a, and the first sensor 132a changes the physical signal it provides, for example, the first sensor 132a displays red light or the first sensor 132a displays "closed". Figures 2 to 4

[0081] In the initial state, the second branch airflow passage 1121b is open, and the second sensor 132b provides a physical signal, for example, the second sensor 132b displays green light or the second sensor 132b displays "open". When the switching assembly 12 closes the second branch airflow passage 1121b (as shown in the embodiment), the moving part 131 moves to the sensing area of the second sensor 132b, and the second sensor 132b changes the physical signal it provides, for example, the second sensor 132b displays red light or the second sensor 132b displays "closed". Figures 5 to 7

[0082] Please refer to Figures 8 to 10 In some embodiments, the sensing assembly 13 further includes a third sensor 132c. When the switching assembly 12 closes the first branch airflow passage 1121a or the switching assembly 12 closes the second branch airflow passage 1121b, the third sensor 132c provides a physical signal; when the switching assembly 12 simultaneously opens the first branch airflow passage 1121a and the second branch airflow passage 1121b, the moving part 131 moves to the sensing area of the third sensor 132c, and the third sensor 132c changes the physical signal it provides. In order to facilitate the user to judge whether the first branch airflow passage 1121a and the second branch airflow passage 1121b are both open.

[0083] Please refer to Figure 3 Figure 4 In some embodiments, the switching assembly 12 includes a driving part 121 and a sealing part 122 connected to the driving part 121, the sealing part 122 is accommodated in the main airflow passage 1111, and under the driving of the driving part 121, the sealing part 122 can move to cover the confluence 113 of the branch airflow passage 1121 communicating with the main airflow passage 1111.

[0084] Please refer to Figure 3 ​​​The branch air flow passage 1121 is communicated with the main air flow passage 1111 at a converging inlet 113 of the branch air flow passage 1121. When the sealing member 122 is rotated to cover the converging inlet 113 of the branch air flow passage 1121 communicated with the main air flow passage 1111, the sealing member 122 can close the branch air flow passage 1121.

[0085] In some embodiments, the sealing member 122 is connected with the moving member 131 and can drive the moving member 131 to move synchronously. Under the driving of the driving member 121, the sealing member 122 can be moved to cover the converging inlet 113 of the branch air flow passage 1121 communicated with the main air flow passage 1111, and at least part of the moving member 131 can be moved to the sensing area of the sensor 132 corresponding to the covered branch air flow passage 1121.

When the driving member 121 drives the sealing member 122 to move to close the branch air flow passage 1121, the moving member 131 can move with the sealing member 122 and move to the sensing area of the sensor 132 corresponding to the closed branch air flow passage 1121.

The sensing assembly 13 comprises three sensors 132, which are a first sensor 132a, a second sensor 132b and a third sensor 132c, respectively.

The first sensor 132a corresponds to the position of the first branch air flow passage 1121a, the second sensor 132b corresponds to the position of the second branch air flow passage 1121b, and the third sensor 132c is located between the first sensor 132a and the second sensor 132b.

[0090] Please refer toFigure 4 The rotating member 123 and the rotating shaft 134 are coaxially arranged, and the driving member 121 is configured to drive the rotating member 123 and the rotating shaft 134 to rotate synchronously.

[0091] In some embodiments, the driving member 121 is a manual member, such as a knob, a handle, etc. The driving member 121 is held by a user and is configured to drive the rotating member 123 and the rotating shaft 134 to rotate synchronously under the operation of the user.

[0092] In some embodiments, the driving member 121 is an electrical element, such as an electric motor. The driving end of the driving member 121 is connected to the rotating member 123 and / or the rotating shaft 134. The driving member 121 is configured to drive the rotating member 123 and the rotating shaft 134 to rotate synchronously.

[0093] In some embodiments, the switching assembly 12 further comprises a speed-reducing member 124. The input end of the speed-reducing member 124 is connected to the driving end of the driving member 121. The output end of the speed-reducing member 124 is connected to the rotating member 123 and / or the rotating shaft 134. The speed-reducing member 124 is configured to be activated by the driving member 121 and output appropriate rotating speed and torque to adjust the rotating speed and torque of the rotating member 123 and the rotating shaft 134, so as to achieve speed reduction and force increase.

[0094] Optionally, the speed-reducing member 124 can be a single-stage transmission or a multi-stage transmission. The speed-reducing member 124 can be a planetary gear transmission assembly (planetary reducer) to achieve speed reduction and force increase.

[0095] Please refer to Figure 11 In some embodiments, the sealing member 122 comprises a main plate 1221 and a sealing plate 1222 connected to the main plate 1221. The sealing plate 1222 is configured to close the branch airflow passage 1121.

[0096] Please refer to Figure 11 In some embodiments, the sealing plate 1222 comprises a main part 12221 and a sealing part 12222. The main part 12221 is connected to the main plate 1221. The sealing part 12222 is arranged around the main part 12221. The main part 12221 is configured to cover the converging inlet 113 of the branch airflow passage 1121. The sealing part 12222 is configured to abut the end face of the converging inlet 113.

[0097] At least the sealing part 12222 of the sealing plate 1222 is a deformable soft rubber member. Optionally, the sealing plate 1222 is a soft rubber member as a whole. Optionally, the material of the sealing plate 1222 is an elastic material, such as silicone or rubber.

[0098] Please refer to Figure 11 In some embodiments, the sealing part 12222 protrudes from the main part 12221 in the direction away from the main plate 1221 (X direction and Y direction in the drawings).

[0099] As shown in the Y direction of the figure, the sealing part 12222 protrudes from the main part 12221, so that the size of the sealing part 12222 is larger than the size of the inlet 113, so that the sealing part 12222 can be attached to the end face of the outer periphery of the inlet 113 to enhance the sealing performance of the sealing plate 1222 and the branch airflow passage 1121; as shown in the X direction of the figure, the sealing part 12222 protrudes from the main part 12221, so that the sealing part 12222 and the main part 12221 have a height difference, when the sealing plate 1222 covers the inlet 113, the sealing part 12222 deforms, so that the gas in the space between the sealing part 12222 and the main part 12221 is discharged to form a negative pressure, which can prevent the sealing member 122 from being blown open by high pressure.

[0100] Please refer to Figure 11 In some embodiments, the sealing plate 1222 further comprises a turning part 12223 connected between the sealing part 12222 and the main part 12221, and the main part 12221, the turning part 12223 and the sealing part 12222 enclose a buffer groove 12224 recessed towards the main plate 1221. The buffer groove is recessed towards the main plate 1221, which is more conducive to the deformation of the sealing part 12222, and more conducive to discharging the gas in the space between the sealing part 12222 and the main part 12221 to form a negative pressure, ensuring that the sealing member 122 stably blocks the inlet 113.

[0101] Please refer to Figures 2 to 10 In the embodiment shown, the gas path switching mechanism 1 has two branch airflow passages 1121, which are a first branch airflow passage 1121a and a second branch airflow passage 1121b, and the first branch airflow passage 1121a and the second branch airflow passage 1121b are spaced apart around the rotation axis of the rotating member 123, and the sealing member 122 is located between the first branch airflow passage 1121a and the second branch airflow passage 1121b. The sealing member 122 comprises two sealing plates 1222, which are respectively arranged on opposite sides of the main plate 1221, and the sealing member 122 can rotate in the main airflow passage 1111 to close the first branch airflow passage 1121a with one of the sealing plates 1222, and the sealing member 122 can rotate in the main airflow passage 1111 in the opposite direction to close the second branch airflow passage 1121b with the other sealing plate 1222.

[0102] It should be noted that, in the case that part of the branch air flow passages 1121 are opened and part of the branch air flow passages 1121 are closed, when air flows through the opened branch air flow passages 1121, the air pressure in the main air flow passage 1111 is less than the air pressure in the closed branch air flow passages 1121, and the sealing member 122 can be forced to move due to the large difference between the air pressure in the main air flow passage 1111 and the air pressure in the closed branch air flow passages 1121, causing the branch air flow passages 1121 that do not need to be opened to be opened.

[0103] For reference Figure 1 In some embodiments, the flow paths of the main air flow passage 1111 and the flow paths of the at least one branch air flow passage 1121 are at an angle to each other, so that the air path composed of the main air flow passage 1111 and the branch air flow passage 1121 is a bent air path, avoiding the sealing member 122 being forced to move due to too large negative pressure.

[0114] Please refer to Figure 1 To achieve the above object, the technical scheme adopted by the second aspect embodiment of the present application is as follows: a cleaning system comprising the base station of the first aspect embodiment and a plurality of cleaning devices.

[0115] The cleaning device is provided with a dust outlet, and the dust outlet is in communication with the branch airflow channel 1121.

[0116] By applying the base station of the first aspect embodiment to the cleaning system, the total number of base stations in the multifunctional cleaning system can be reduced, so that the integration of the multifunctional cleaning system can be realized, and the total space occupied by the multifunctional cleaning system can be reduced.

[0117] Optionally, the plurality of cleaning devices include a sweeping device, a dust collecting device, a washing device, etc.

[0118] The cleaning system of the present application will be described below in conjunction with an embodiment. Please refer to Figure 1 The cleaning system includes a base station, a sweeping device 4a, and a dust collecting device 4b. The base station includes an air path switching mechanism 1, a dust collecting bin 2, a dust extraction pipe 3, a set of fan modules 8, a set of front filters 5, a set of rear filters 6, and a set of dust bags 7.

The fan modules 8 are connected to one end of the dust collecting bin 2 away from the dust extraction pipe 3. Under the drive of the fan modules 8, air flow can flow into the dust collecting space 21 through the dust extraction passage 31, and then flow out of the dust collecting space 21 in sequence through the dust bags 7, the front filters 5, and finally through the rear filters 6 to be discharged out of the base station. The front filters 5, the rear filters 6, and the dust bags 7 can collect dust and debris in the air flow.

[0119] The cleaning system further includes a controller and a display. The controller can be a remote controller, control software on an electronic device, a control panel on the cleaning system, etc. A user can operate the controller to control the driving member 121 to work, so that the driving member 121 drives the sealing member 122 to rotate in the main air flow pipe 111 to change the opening and closing states of the first branch air flow passage 1121a and the second branch air flow passage 1121b. The display is electrically connected to the inductor 132. The display receives and displays the physical signals provided by the inductor 132 in the sensing assembly 13. For example, if the first branch air flow passage 1121a is closed, the display outputs the sentence "sweeping passage closed"; if the first branch air flow passage 1121a is open, the display outputs the sentence "sweeping passage open"; if the second branch air flow passage 1121b is closed, the display outputs the sentence "dust collecting passage closed"; and if the second branch air flow passage 1121b is open, the display outputs the sentence "dust collecting passage open".

The user can operate the controller to control the driving member 121 to work, so that the sealing member 122 rotates to open the second branch air flow channel 1121b (see FIG. 12B), the display outputs the statement "sweeping channel closed" and the statement "suction channel open", and the user can operate the controller to start the fan module 8 in the base station to work, and then the user can hold the suction device 4b to perform cleaning work, so that the air flow enters the cleaning system through the suction device 4b, and then sequentially flows through the second branch air flow channel 1121b, the main air flow channel 1111, the dust extraction channel 31, the dust bag 7, the pre-filter 5 and the post-filter 6, so as to store the dust and debris collected by the suction device 4b in the dust collection space 21 of the dust collection bin 2. After the sweeping device 4a completes the cleaning work, the sweeping device 4a moves to the base station, and the dust outlet of the sweeping device 4a communicates with the first branch air flow channel 1121a, the user can operate the controller to control the driving member 121 to work, so that the sealing member 122 rotates to open the first branch air flow channel 1121a (see FIG. 12A), the display outputs the statement "sweeping channel open" and the statement "suction channel closed", and the user can operate the controller to start the fan module 8 in the base station to work, so that the air flow enters the first branch air flow channel 1121a after passing through the sweeping device 4a, and then sequentially flows through the main air flow channel 1111, the dust extraction channel 31, the dust bag 7, the pre-filter 5 and the post-filter 6, so as to collect the dust and debris collected in the sweeping device 4a into the dust collection space 21.
