[0055] 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.

[0056] 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 to place multiple base stations at the same time in a family that configures multiple household cleaning systems at the same time, thereby causing multiple household cleaning systems to occupy a large space.

[0057] In view of the above problems, the present application provides a base station and a cleaning system, aiming to solve the technical problem that the cleaning system occupies a large space.

[0058] In order to illustrate the technical scheme of the present application, the following will be described in conjunction with specific drawings and embodiments.

[0059] Please refer to Figures 1 to 9 The embodiment of the present application provides 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.

[0060] The dust collecting pile 2 has a dust collecting space 21; the air path switching mechanism 1 comprises a pipeline assembly 11 and a switching assembly 12. The pipeline assembly 11 is connected with the dust collecting pile 2, and the pipeline assembly 11 has a main air flow channel 1111 and a plurality of air inlets 113, at least part of the air inlets 113 are arranged at a circumferential interval of the main air flow channel 1111, the main air flow channel 1111 is communicated with the dust collecting space 21, and the air inlets 113 are used for being communicated with dust outlets of the cleaning device; the switching assembly 12 comprises a switching pipe 121, the switching pipe 121 is arranged in the main air flow channel 1111 in a rotatable manner around an axial direction of the main air flow channel 1111, and the switching pipe 121 is communicated with the main air flow channel 1111, when the switching pipe 121 rotates, the communication state of at least one air inlet 113 with the main air flow channel 1111 can be changed.

[0061] It should be noted that the communication state of the air inlet 113 with the main air flow channel 1111 includes that the air inlet 113 is communicated with the main air flow channel 1111, the air inlet 113 is partially communicated with the main air flow channel 1111 or the air inlet 113 is closed relative to the main air flow channel 1111.

[0062] It should be noted that the air inlet 113 is arranged on an inner wall surface of the main air flow channel 1111, the direction of the air inlet 113 can be but is not limited to perpendicular to the axial direction of the main air flow channel 1111, and the outer space of the pipeline assembly 11 and the main air flow channel 1111 are both communicated with the air inlet 113; the switching pipe 121 is accommodated in the main air flow channel 1111, and the switching pipe 121 is attached to the inner wall surface of the main air flow channel 1111.

[0063] In the embodiment of the present application, in the direction in which the plurality of air inlets 113 are distributed, the pipe wall of the switching pipe 121 is not continuously arranged, that is, in the direction in which the plurality of air inlets 113 are distributed, the pipe wall of the switching pipe 121 is formed with a gap 1211. When the pipe wall of the switching pipe 121 covers the air inlet 113, the air inlet 113 is closed; when the gap 1211 on the switching pipe 121 faces the air inlet 113, the air inlet 113 is opened, the air inlet 113 can be communicated with the switching pipe 121 through the gap 1211, that is, the air inlet 113 can be communicated with the main air flow channel 1111 through the switching pipe 121. With the rotation of the switching pipe 121, the above-mentioned gap 1211 can face one of the air inlets 113, the above-mentioned gap 1211 can face a plurality of air inlets 113, and the above-mentioned gap 1211 can face all the air inlets 113, so that at least one air inlet 113 is opened and communicated with the main air flow channel 1111 through the switching pipe 121.

[0064] Please refer to Figure 2 and Figure 3In the embodiment of the present application, the pipeline assembly 11 comprises a main airflow pipe 111 and a plurality of branch airflow pipes. One end of the main airflow pipe 111 is connected to the dust collecting bin 2, and the other end of the main airflow pipe 111 is connected to the plurality of branch airflow pipes. One end of each branch airflow pipe is connected to the main airflow pipe 111, and the other end of each branch airflow pipe is used to be connected to a cleaning device. The main airflow pipe 111 is provided with a main airflow passage 1111, and each branch airflow pipe is provided with a branch airflow passage 1121 which is in communication with the main airflow passage 1111. The air inlet 113 is a communication port of the branch airflow passage 1121 and the main airflow passage 1111. Each branch airflow passage 1121 can form an air path together with the main airflow passage 1111 to form a plurality of air paths in the air path switching mechanism 1. Different air paths are connected to different dust outlet ports of different cleaning devices at one end and are connected to the same dust collecting space 21 at the other end. When the air inlet 113 is opened by rotating the switching pipe 121, the air path in which the opened air inlet 113 is located is conducted. When the air inlet 113 is closed by rotating the switching pipe 121, the air path in which the closed air inlet 113 is located is closed.

[0065] With the rotation of the switching pipe 121, all the air inlets 113 can be opened at the same time. With the rotation of the switching pipe 121, any one air inlet 113 or any multiple air inlets 113 can be selectively opened. By changing the number and position of the opened air inlets 113, the air path can be switched.

[0066] If it is needed to store the dust and sundries collected by the cleaning devices into the dust collecting space 21, the switching pipe 121 needs to be rotated to open the air inlets 113 in the air paths which are in communication with the cleaning devices to be discharged, and to close the air inlets 113 in the remaining air paths.

[0067] For example, in the case of cleaning the floor, the switching pipe 121 needs to be rotated to open the air inlets 113 in the air paths which are in communication with the floor cleaning devices, and to close the air inlets 113 in the air paths which are in communication with the window cleaning devices. Figures 1 to 9In the shown embodiment, the pipeline assembly 11 comprises two branch airflow pipes, i.e., a first branch airflow pipe 112a and a second branch airflow pipe 112b; the first branch airflow pipe 112a is provided with a first branch airflow passage 1121a, and the second branch airflow pipe 112b is provided with a second branch airflow passage 1121b. The base station is connectable to two cleaning devices, i.e., a first cleaning device 3a and a second cleaning device 3b; the first cleaning device 3a is connected to the first branch airflow pipe 112a, and a dust outlet in the first cleaning device 3a is in communication with the first branch airflow passage 1121a; the second cleaning device 3b is connected to the second branch airflow pipe 112b, and a dust outlet in the second cleaning device 3b is in communication with the second branch airflow passage 1121b. The air inlet 113 is provided with two air inlets, i.e., a first air inlet 113a and a second air inlet 113b; the first air inlet 113a is a communication port of the first branch airflow passage 1121a and the main airflow passage 1111, and the second air inlet 113b is a communication port of the second branch airflow passage 1121b and the main airflow passage 1111.

[0068] Please refer to Figure 1 , Figure 2 and Figure 3 When the dust collecting bin 2 needs to store the dust and sundries collected by the first cleaning device 3a, the switching pipe 121 is rotated so that the notch 1211 on the switching pipe 121 is aligned with the first air inlet 113a; the first branch airflow passage 1121a is in communication with the main airflow passage 1111 via the switching pipe 121, so that the dust and sundries in the first cleaning device 3a can flow into the dust collecting space 21 via the first branch airflow passage 1121a, the switching pipe 121 and the main airflow passage 1111.

[0069] Please refer to Figure 1 , Figure 4 and Figure 5 When the dust collecting bin 2 needs to store the dust and sundries collected by the first cleaning device 3a and the second cleaning device 3b, the switching pipe 121 is rotated so that the notch 1211 on the switching pipe 121 is aligned with the first air inlet 113a and the second air inlet 113b; the first branch airflow passage 1121a and the second branch airflow passage 1121b are both in communication with the main airflow passage 1111 via the switching pipe 121, so that the dust and sundries in the first cleaning device 3a can flow into the dust collecting space 21 via the first branch airflow passage 1121a, the switching pipe 121 and the main airflow passage 1111, and the dust and sundries in the second cleaning device 3b can flow into the dust collecting space 21 via the second branch airflow passage 1121b, the switching pipe 121 and the main airflow passage 1111.

[0070] Please refer to Figure 1 , Figure 6 andFigure 7 When the dust bin 2 is required to store dust and debris collected by the second cleaning device 3b, the switching pipe 121 is rotated so that the notch 1211 on the switching pipe 121 is aligned with the second air inlet 113b; so that the second branch air flow passage 1121b is in communication with the main air flow passage 1111 via the switching pipe 121, so that dust and debris in the second cleaning device 3b can flow into the dust storage space 21 via the second branch air flow passage 1121b, the switching pipe 121 and the main air flow passage 1111.

[0071] 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 having three cleaning devices, four cleaning devices or more cleaning devices.

[0072] In the base station provided in the present application, the communication state between at least one air inlet 113 and the main air flow passage 1111 can be changed by rotating the switching pipe 121, so as to adjust the number and position of the air inlets 113 in communication with the main air flow passage 1111, so that the air inlets 113 in communication with the cleaning device to be operated can be in communication with the dust bin 2 via the main air flow passage 1111. In this way, one base station can be connected to multiple cleaning devices, so as to reduce the total number of base stations in a multi-functional cleaning system, so as to realize the integration of a multi-functional cleaning system and reduce the total space occupied by the multi-functional cleaning system.

[0073] In some embodiments, the switching pipe 121 has a notch 1211 on the side wall thereof, and the notch 1211 can be in communication with at least one air inlet 113 as the switching pipe 121 is rotated.

[0074] Please refer to Figure 10 and Figure 11 In some embodiments, the notch 1211 can include a plurality of communication holes 12111, and the plurality of communication holes 12111 are arranged at intervals in the direction in which the plurality of air inlets 113 are distributed, so that the pipe wall of the switching pipe 121 is not continuously arranged, and the plurality of communication holes 12111 constitute the notch 1211. When the pipe wall between the communication holes 12111 covers the air inlet 113, the air inlet 113 is closed; when the aperture of the communication hole 12111 on the switching pipe 121 faces the air inlet 113, the air inlet 113 is in communication with the communication hole 12111, and the air inlet 113 is opened, so that the air inlet 113 is in communication with the main air flow passage 1111 via the switching pipe 121.

[0075] With the rotation of the switching pipe 121, one of the air inlets 113 is communicated with one of the communication holes 12111; or with the rotation of the switching pipe 121, the air inlets 113 are communicated with the communication holes 12111 one by one; or with the rotation of the switching pipe 121, all the air inlets 113 are communicated with the communication holes 12111 one by one; so that at least one of the air inlets 113 can be opened and communicated with the main airflow channel 1111 through the switching pipe 121.

[0076] Please refer to Figures 2 to 9 In some embodiments, the air inlets 113 are provided with two, and the orientations of the two air inlets 113 are located on the same straight line, the gap 1211 includes three communication holes 12111, and the three communication holes 12111 are sequentially distributed in the circumferential direction of the main airflow channel 1111, wherein the axial directions of two of the communication holes 12111 coincide, and the axial direction of the other communication hole 12111 is not parallel to the axial directions of the two communication holes 12111.

[0077] In the above embodiments, with the rotation of the switching pipe 121, the two communication holes 12111 whose axial directions coincide are respectively oriented towards one of the air inlets 113, so that both of the air inlets 113 are communicated with the main airflow channel 1111 through the switching pipe 121 (as shown in Figure 5 and Figure 9 ); with the rotation of the switching pipe 121, the communication hole 12111 between the two communication holes 12111 whose axial directions coincide is oriented towards one of the air inlets 113, and the other air inlet 113 is covered by the pipe wall of the switching pipe 121, so that one of the air inlets 113 is communicated with the main airflow channel 1111 through the switching pipe 121, and the other air inlet 113 is closed (as shown in Figure 3 and Figure 7 ).

[0078] In some embodiments, the three communication holes 12111 are sequentially distributed in the circumferential direction of the main airflow channel 1111, and the axial directions of adjacent communication holes 12111 are arranged at an angle of 90 degrees, that is, the axial directions of two of the three communication holes 12111 coincide, and the axial direction of the other communication hole 12111 is arranged at an angle of 90 degrees.

[0080] Optionally, the first angle can be 90 degrees, 60 degrees, 45 degrees, 30 degrees, etc.

[0081] Please refer toFigure 10 and Figure 11 In some embodiments, one end of the switching pipe 121 is an open pipe mouth, and the other end of the switching pipe 121 is a closed blocking end. The pipe mouth and the blocking end are respectively located on two sides of the air inlet 113 in the axial direction of the main airflow passage 1111, and the pipe mouth is in communication with the main airflow passage 1111.

[0082] Please refer to Figure 12 In some embodiments, the notch 1211 can also be a through slot, which penetrates the switching pipe 121 in the radial direction of the main airflow passage 1111.

[0083] Please refer to Figure 13 In some embodiments, one end of the switching pipe 121 is an open pipe mouth, and the other end of the switching pipe 121 is a semi-closed blocking end. The notch 1211 is formed in the semi-closed blocking end. The blocking end is arranged in alignment with the air inlet 113 in the axial direction of the main airflow passage 1111, and the pipe mouth is in communication with the main airflow passage 1111.

In order to prevent the air inlet 113 from being in communication with the main airflow passage 1111 through the gap between the switching pipe 121 and the inner wall surface of the main airflow passage 1111.

[0087] Please refer to Figure 2 In some embodiments, the air path switching mechanism 1 further comprises a sensing assembly 13, which is used to detect whether each air inlet 113 is open.

[0088] The opening of the air inlet 113 can be determined according to the detection result of the sensing assembly 13, so that the user adjusts the position of the switching pipe 121 according to the demand, so that the switching pipe 121 closes or opens all air inlets 113, or so that the switching pipe 121 opens a certain sub-air inlet 113 or multiple air inlets 113 that are in communication with the dust outlet of the cleaning device to be cleaned; it is convenient for the user to distinguish which air inlets 113 are opened and which air inlets 113 are closed.

[0089] For example, in the embodiment shown in Figures 1 to 9 In the embodiment shown in the embodiment, the base station can be connected with two cleaning devices, and the two cleaning devices are respectively a first cleaning device 3a and a second cleaning device 3b; the air path switching mechanism 1 has two branch air flow channels 1121, and the two branch air flow channels 1121 are respectively a first branch air flow channel 1121a for communicating with the first cleaning device 3a and a second branch air flow channel 1121b for communicating with the second cleaning device 3b. The air inlet 113 is provided with two air inlets 113, and the two air inlets 113 are respectively a first air inlet 113a and a second air inlet 113b, the first air inlet 113a is a communication port of the first branch air flow channel 1121a and the main air flow channel 1111, and the second air inlet 113b is a communication port of the second branch air flow channel 1121b and the main air flow channel 1111. When the first air inlet 113a is opened, the first branch air flow channel 1121a and the main air flow channel 1111 can be communicated, so that the dust collecting bin 2 can store the dust and sundries collected by the first cleaning device 3a; when the second air inlet 113b is opened, the second branch air flow channel 1121b and the main air flow channel 1111 can be communicated, so that the dust collecting bin 2 can store the dust and sundries collected by the second cleaning device 3b.

[0090] Please refer to Figure 1 、 Figure 2 and Figure 3 When the dust collecting bin 2 needs to store the dust and sundries collected by the first cleaning device 3a, the switching pipe 121 is rotated, and the opening and closing state of the first air inlet 113a is determined according to the detection result of the sensing assembly 13. If the first air inlet 113a is in the open state, the base station can be started; otherwise, continue to rotate the switching pipe 121 until the first air inlet 113a is in the open state.

[0091] Please refer to Figure 1 、 Figure 4 and Figure 5When the dust collecting pile 2 needs to store the dust and debris collected by the first cleaning device 3a and the second cleaning device 3b, the switching pipe 121 is rotated, and the opening and closing states of the first air inlet 113a and the second air inlet 113b are determined according to the detection result of the sensing assembly 13. If the first air inlet 113a and the second air inlet 113b are both in the open state, the base station can be started; otherwise, the switching pipe 121 is continuously rotated until the first air inlet 113a and the second air inlet 113b are both in the open state.

[0092] Please refer to Figure 1 、 Figure 6 and Figure 7 When the dust collecting pile 2 needs to store the dust and debris collected by the second cleaning device 3b, the switching pipe 121 is rotated, and the opening and closing state of the second air inlet 113b is determined according to the detection result of the sensing assembly 13. If the second air inlet 113b is in the open state, the base station can be started; otherwise, the switching pipe 121 is continuously adjusted until the second air inlet 113b is in the open state.

[0093] Please refer to Figure 2 In some embodiments, the sensing assembly 13 includes a plurality of sensors 131 and a moving piece 132. The sensors 131 are arranged on the pipe assembly 11, and each sensor 131 corresponds to an air inlet 113. The moving piece 132 is connected to the switching pipe 121. When the switching pipe 121 is rotated to close the air inlet 113, at least part of the moving piece 132 moves to the sensing area of the sensor 131 corresponding to the closed air inlet 113.

[0094] By adopting the above technical solution, the position of the moving piece 132 changes with the rotation of the switching pipe 121, so that the position of the moving piece 132 can correspond to the position of the switching pipe 121. When the switching pipe 121 closes the air inlet 113, the moving piece 132 can be rotated to the sensing area of the sensor 131 corresponding to the closed air inlet 113.

[0095] In the above embodiments, each sensor 131 corresponds to an air inlet 113, so that the sensing assembly 13 can individually detect the opening and closing state of each air inlet 113, thereby improving the detection reliability of the sensing assembly 13.

[0096] The inductive assembly 13 further comprises a display corresponding to the inductor 131, which provides a physical signal that can be directly perceived by the user according to the detection result of the inductor 131. When the inductor 131 senses that the air inlet 113 is in the open state, the display can react and output the physical signal. When the inductor 131 senses that the air inlet 113 is in the closed state, the display can react and change the output physical signal, so that the user can determine the opening and closing state of the air inlet 113 corresponding to the inductor 131 according to the physical signal.

[0097] By adopting the above scheme, the inductive assembly 13 can quickly induct the state of the air inlet 113 by following the rotation of the switching pipe 121, and the user can know the working state of the cleaning system in time according to the physical information provided by the inductor 131.

[0098] In some embodiments, the physical signal that can be directly perceived by the user provided by the display is a light signal, and the display displays different colors of light to correspond to the state of the air inlet 113. For example, the display displays green light to indicate that the air inlet 113 corresponding to the inductor 131 is in the open state; and the display displays red light to indicate that the air inlet 113 corresponding to the inductor 131 is in the closed state.

[0099] In some embodiments, the physical signal that can be directly perceived by the user provided by the display is a pattern signal, and the display displays different visual information to correspond to the state of the air inlet 113. For example, the display displays “open” to indicate that the air inlet 113 corresponding to the inductor 131 is in the open state; and the display displays “close” to indicate that the air inlet 113 corresponding to the inductor 131 is in the closed state.

[0100] In other embodiments, the physical signal that can be directly perceived by the user provided by the display is a sound signal, and the display outputs different sentences to correspond to the state of the air inlet 113. For example, the display outputs the sentence “sweeping passage open” to indicate that the air inlet 113 corresponding to the inductor 131 is used for communication with the dust outlet of the sweeping device and is in the open state; and the display outputs the sentence “sweeping passage closed” to indicate that the air inlet 113 corresponding to the inductor 131 is used for communication with the dust outlet of the sweeping device and is in the closed state.
