[0054] Currently, 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.

[0055] 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.

[0056] 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.

[0057] In order to illustrate the technical scheme of the present application, the following will be described in conjunction with specific drawings and embodiments.

[0058] Please refer to Figures 1 to 11 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.

[0059] 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 communication cavity 113, a main air flow channel 1111 in communication with the communication cavity 113, and a plurality of branch air flow channels 1121 in communication with the communication cavity 113, the main air flow channel 1111 is in communication with the dust collecting space 21, and the branch air flow channels 1121 are used to communicate with dust outlets of cleaning devices; the switching assembly 12 comprises a ball valve 121, the ball valve 121 is rotatably arranged in the communication cavity 113, and at least one branch air flow channel 1121 can be in communication with the main air flow channel 1111 through the ball valve 121 with rotation of the ball valve 121.

[0060] In some embodiments, the main air flow channel 1111 and the plurality of branch air flow channels 1121 are circumferentially spaced apart in the communication cavity 113, and the ball valve 121 is rotatably arranged in the communication cavity 113 in a distribution direction of the main air flow channel 1111 and the branch air flow channels 1121.

[0061] It should be noted that the main air flow channel 1111 and the plurality of branch air flow channels 1121 are circumferentially spaced apart in the communication cavity 113, and the main air flow channel 1111 and the branch air flow channels 1121 are both in communication with the communication cavity 113, the ball valve 121 is accommodated in the communication cavity 113, and an outer wall surface of the ball valve 121 is attached to an inner wall surface of the communication cavity 113. In the embodiments of the present application, the outer wall surface of the ball valve 121 is not continuously arranged in the distribution direction of the main air flow channel 1111 and the plurality of branch air flow channels 1121, that is, a gap 1211 is formed on the ball valve 121 in the distribution direction of the main air flow channel 1111 and the plurality of branch air flow channels 1121. When the outer wall surface of the ball valve 121 covers the communication position of the main air flow channel 1111 and the communication cavity 113, the main air flow channel 1111 is closed; when the gap 1211 on the ball valve 121 is directed to the communication position of the main air flow channel 1111 and the communication cavity 113, the main air flow channel 1111 is opened; when the outer wall surface of the ball valve 121 covers the communication position of the branch air flow channel 1121 and the communication cavity 113, the branch air flow channel 1121 is closed; when the gap 1211 on the ball valve 121 is directed to the communication position of the branch air flow channel 1121 and the communication cavity 113, the branch air flow channel 1121 is opened. With rotation of the ball valve 121, the above-mentioned gap 1211 can be directed to the communication position of the main air flow channel 1111 and the communication cavity 113 (so that the gap 1211 is in communication with the main air flow channel 1111), and the gap 1211 can be directed to the communication position of at least one branch air flow channel 1121 and the communication cavity 113 (so that the gap 1211 is in communication with the at least one branch air flow channel 1121), so that the at least one branch air flow channel 1121 is in communication with the main air flow channel 1111 through the ball valve 121.

[0062] Please refer toFigure 1 、 Figure 2 and Figure 4 In the embodiment of the present application, the pipeline assembly 11 comprises a main airflow pipe 111 and a plurality of branch airflow pipes 112. 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 112. One end of each branch airflow pipe 112 is connected to the main airflow pipe 111, and the other end of each branch airflow pipe 112 is used to be connected to a cleaning device. The main airflow pipe 111 is provided with a main airflow passage 1111, each branch airflow pipe 112 is provided with a branch airflow passage 1121, and a communication cavity 113 is provided at the connection between the main airflow pipe 111 and each branch airflow pipe 112. Each branch airflow passage 1121 can form an air path together with the communication cavity 113 and 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 outlets of different cleaning devices at one end and are connected to the same dust collecting space 21 at the other end. When the branch airflow passage 1121 is opened by rotating the ball valve 121 and the branch airflow passage 1121 is connected to the main airflow passage 1111 through the ball valve 121, the air path in which the opened branch airflow passage 1121 is located is conducted. When the branch airflow passage 1121 is closed by rotating the ball valve 121, the air path in which the closed branch airflow passage 1121 is located is closed.

[0063] With the rotation of the ball valve 121, all branch airflow passages 1121 can be opened at the same time, and all branch airflow passages 1121 can be connected to the main airflow passage 1111 through the ball valve 121. With the rotation of the ball valve 121, any one branch airflow passage 1121 or any multiple branch airflow passages 1121 can be selectively opened and connected to the main airflow passage 1111 through the ball valve 121. The air path can be switched by rotating the ball valve 121.

[0064] If it is needed to store the dust and sundries collected by the cleaning device into the dust collecting space 21, the ball valve 121 needs to be rotated to open the air path connected to the cleaning device to be discharged.

[0065] For example, in Figures 1 to 11In the shown embodiment, the pipeline assembly 11 comprises two branch airflow pipes 112, which are respectively 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; the second branch airflow pipe 112b is provided with a second branch airflow passage 1121b. The base station can be connected with two cleaning devices, which are respectively a first cleaning device 3a and a second cleaning device 3b; the first cleaning device 3a is connected with the first branch airflow pipe 112a, and the 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 with the second branch airflow pipe 112b, and the dust outlet in the second cleaning device 3b is in communication with the second branch airflow passage 1121b.

[0066] Please refer to Figure 1 , Figure 2 and Figure 4 , 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 ball valve 121 is rotated, so that the gap 1211 on the ball valve 121 is aligned with the communication between the first branch airflow passage 1121a and the communication cavity 113, the communication between the second branch airflow passage 1121b and the communication cavity 113, and the communication between the main airflow passage 1111 and the communication cavity 113; so that the first branch airflow passage 1121a and the second branch airflow passage 1121b are both in communication with the main airflow passage 1111 through the ball valve 121, so that the dust and sundries in the first cleaning device 3a can flow into the dust collecting space 21 through the first branch airflow passage 1121a, the ball valve 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 through the second branch airflow passage 1121b, the ball valve 121 and the main airflow passage 1111.

[0067] Please refer to Figure 1 , Figure 6 and Figure 8 , when the dust collecting bin 2 needs to store the dust and sundries collected by the first cleaning device 3a, the ball valve 121 is rotated, so that the gap 1211 on the ball valve 121 is aligned with the communication between the first branch airflow passage 1121a and the communication cavity 113, and the communication between the main airflow passage 1111 and the communication cavity 113; so that the first branch airflow passage 1121a is in communication with the main airflow passage 1111 through the ball valve 121, so that the dust and sundries in the first cleaning device 3a can flow into the dust collecting space 21 through the first branch airflow passage 1121a, the ball valve 121 and the main airflow passage 1111.

[0068] Please refer to Figure 1 , Figure 9 and Figure 11When the dust collecting post 2 is required to store the dust and debris collected by the second cleaning device 3b, the ball valve 121 is rotated so that the gap 1211 on the ball valve 121 is aligned with the connection between the second branch air flow passage 1121b and the communication cavity 113 and the connection between the main air flow passage 1111 and the communication cavity 113; so that the second branch air flow passage 1121b is communicated with the main air flow passage 1111 through the ball valve 121, so that the dust and debris in the second cleaning device 3b can flow into the dust collecting space 21 through the second branch air flow passage 1121b, the ball valve 121 and the main air flow passage 1111.

[0069] 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.

[0070] In the base station provided in the present application, at least one branch air flow passage 1121 can be opened and communicated with the main air flow passage 1111 through the ball valve 121 by rotating the ball valve 121, so that the cleaning device communicated with the opened branch air flow passage 1121 can be communicated with the dust collecting post 2, thus, one base station can be connected with at least one cleaning device, so as to reduce the total number of base stations in a multi-functional cleaning system, so as to realize the integration of the multi-functional cleaning system and reduce the total space occupied by the multi-functional cleaning system.

[0071] Please refer to Figure 11 and Figure 12 In some embodiments, the gap 1211 includes at least three communication holes, the communication holes are communicated with each other, and the communication holes are arranged at intervals around the rotation axis of the ball valve 121, and with the rotation of the ball valve 121, one of the communication holes can be communicated with the main air flow passage 1111, and at least one of the communication holes can be communicated with one branch air flow passage 1121.

[0072] In the above embodiment, the plurality of communication holes are arranged at intervals around the rotation axis of the ball valve 121, so that the pipe wall of the ball valve 121 is not continuously arranged, and the plurality of communication holes constitute the above-mentioned notch 1211. When the outer wall surface of the ball valve 121 between the orifices of the communication holes covers the communication between the main gas flow channel 1111 and the communication cavity 113, the main gas flow channel 1111 is closed; when the orifices of the communication holes on the ball valve 121 face the communication between the main gas flow channel 1111 and the communication cavity 113, the main gas flow channel 1111 is opened; when the outer wall surface of the ball valve 121 between the orifices of the communication holes covers the communication between the branch gas flow channel 1121 and the communication cavity 113, the branch gas flow channel 1121 is closed; when the orifices of the communication holes on the ball valve 121 face the communication between the branch gas flow channel 1121 and the communication cavity 113, the branch gas flow channel 1121 is opened. With the rotation of the ball valve 121, the orifice of one of the communication holes faces the communication between the main gas flow channel 1111 and the communication cavity 113, and the orifice of one of the communication holes faces the communication between one of the branch gas flow channels 1121 and the communication cavity 113, so that one of the branch gas flow channels 1121 is communicated with the main gas flow channel 1111 through the ball valve 121; with the rotation of the ball valve 121, the orifice of one of the communication holes faces the communication between the main gas flow channel 1111 and the communication cavity 113, and the orifices of the plurality of communication holes face the communications between the plurality of branch gas flow channels 1121 and the communication cavity 113, respectively, so that the plurality of branch gas flow channels 1121 are communicated with the main gas flow channel 1111 through the ball valve 121; with the rotation of the ball valve 121, the orifice of one of the communication holes faces the communication between the main gas flow channel 1111 and the communication cavity 113, and the orifices of the rest of the communication holes face the communications between the branch gas flow channels 1121 and the communication cavity 113, respectively, so that all the branch gas flow channels 1121 are communicated with the main gas flow channel 1111 through the ball valve 121.

[0073] Please refer to Figure 11 and Figure 12 In some embodiments, the notch 1211 includes three communication holes, which are a first communication hole 12111, a second communication hole 12112 and a third communication hole 12113, respectively, the second communication hole 12112 and the third communication hole 12113 are located on the two sides of the first communication hole 12111, respectively, and the branch gas flow channel 1121 is provided with two, which are arranged on the two sides of the main gas flow channel 1111, respectively.

When the ball valve 121 is rotated from the state shown in FIG. 12A clockwise, the ball valve 121 is rotated to a state in which the orifice of the first communication hole 12111 faces the communication between the first branch airflow passage 1121a and the communication cavity 113, and the orifice of the third communication hole 12113 faces the inner wall surface of the communication cavity 113 (as shown in FIG. 12B). In this state, the first branch airflow passage 1121a is in communication with the main airflow passage 1111 through the ball valve 121. Figure 14 and Figure 2When the state shown is rotated clockwise by an angle of the first included angle, the ball valve 121 is rotated to a state where the orifice of the second communication hole 12112 is directed to the communication between the main airflow passage 1111 and the communication cavity 113 (as shown in Figures 1 to 12 and Figure 1 the state shown), the orifice of the first communication hole 12111 is directed to the communication between the first branch airflow passage 1121a and the communication cavity 113, and the orifice of the third communication hole 12113 is directed to the inner wall surface of the communication cavity 113, so that the first branch airflow passage 1121a is communicated with the main airflow passage 1111 through the ball valve 121. When the ball valve 121 is rotated counterclockwise by an angle of the first included angle from Figure 2 and Figure 4 the state shown, the ball valve 121 is rotated to a state where the orifice of the third communication hole 12113 is directed to the communication between the main airflow passage 1111 and the communication cavity 113 (as shown in Figure 1 and Figure 6 the state shown), the orifice of the first communication hole 12111 is directed to the communication between the second branch airflow passage 1121b and the communication cavity 113, and the orifice of the second communication hole 12112 is directed to the inner wall surface of the communication cavity 113, so that the second branch airflow passage 1121b is communicated with the main airflow passage 1111 through the ball valve 121.

[0077] In some embodiments, the first included angle is greater than 0 degrees and less than 180 degrees.

[0078] Optionally, the first included angle is 60 degrees, 90 degrees, 110 degrees, etc.

[0079] In some embodiments, the rotation axis of the ball valve 121 passes through the ball center of the ball valve 121.

[0080] Please refer to Figure 8 In some embodiments, the communication holes extend in the radial direction of the ball valve 121, and the communication holes include a first end and a second end distributed in the radial direction of the ball valve 121, the first end is located at the ball center of the ball valve 121, the second end penetrates the ball valve 121, and the first ends of the plurality of communication holes are communicated with each other at the ball center of the ball valve 121.

[0081] Please refer to Figure 1 In some embodiments, the ball valve 121 is provided with a switching cavity 12114, the center of the switching cavity 12114 coincides with the ball center of the ball valve 121. The communication holes penetrate the ball valve 121, and the communication holes are communicated with the switching cavity 12114.

[0082] Please refer to Figure 9 In some embodiments, the notch 1211 can also be a through groove, the through groove penetrates the ball valve 121, and the groove orifice of the through groove extends in the circumferential direction of the ball valve.

[0083] Please refer to Figure 11In some embodiments, the base station further comprises a sensing component 13 for detecting whether the branch airflow passage 1121 is in communication with the main airflow passage 1111.

[0084] The determination of whether the branch airflow passage 1121 is in communication with the main airflow passage 1111 can be made according to the detection result of the sensing component 13, so that the user can adjust the position of the ball valve 121 according to the requirement, all the branch airflow passages 1121 are in communication with the main airflow passage 1111 through the ball valve 121, or some branch airflow passage 1121 or multiple branch airflow passages 1121 in communication with the dust outlet of the cleaning device to be cleaned are in communication with the main airflow passage 1111 through the ball valve 121.

[0085] For example, in the embodiment shown in Figure 2 , the base station can be connected to two cleaning devices, which are the first cleaning device 3a and the second cleaning device 3b; the air path switching mechanism 1 has two branch airflow passages 1121, which are the first branch airflow passage 1121a for communication with the dust outlet of the second cleaning device 3b and the second branch airflow passage 1121b for communication with the dust outlet of the second cleaning device 3b. When the first branch airflow passage 1121a and the second branch airflow passage 1121b are both in communication with the main airflow passage 1111 through the ball valve 121, the dust collecting bin 2 can store the dust and debris collected by the first cleaning device 3a and the second cleaning device 3b at the same time; when the first branch airflow passage 1121a is in communication with the main airflow passage 1111 through the ball valve 121 and the second branch airflow passage 1121b is closed by the ball valve 121, the dust collecting bin 2 can store the dust and debris collected by the first cleaning device 3a; when the second branch airflow passage 1121b is in communication with the main airflow passage 1111 through the ball valve 121 and the first branch airflow passage 1121a is closed by the ball valve 121, the dust collecting bin 2 can store the dust and debris collected by the second cleaning device 3b.

[0086] For example, in the embodiment shown in Figure 3 , Figure 15 and Figure 15When the dust collecting post 2 is required to store the dust and debris collected by the first cleaning device 3a and the second cleaning device 3b, the ball valve 121 is rotated, and it is determined according to the detection result of the sensing assembly 13 whether the first branch airflow passage 1121a and the second branch airflow passage 1121b are both communicated with the main airflow passage 1111 through the ball valve 121; if yes, the base station can be started; otherwise, the ball valve 121 is continuously rotated until the first branch airflow passage 1121a and the second branch airflow passage 1121b are both communicated with the main airflow passage 1111 through the ball valve 121, so that the dust and debris in the first cleaning device 3a can flow into the dust collecting space 21 through the first branch airflow passage 1121a, the ball valve 121 and the main airflow passage 1111, and the dust and debris in the second cleaning device 3b can flow into the dust collecting space 21 through the second branch airflow passage 1121b, the ball valve 121 and the main airflow passage 1111.

[0087] Please refer to Figure 2 、 Figure 3 and Figure 2 When the dust collecting post 2 is required to store the dust and debris collected by the first cleaning device 3a, the ball valve 121 is rotated, and it is determined according to the detection result of the sensing assembly 13 whether the first branch airflow passage 1121a is communicated with the main airflow passage 1111 through the ball valve 121; if yes, the base station can be started; otherwise, the ball valve 121 is continuously rotated until the first branch airflow passage 1121a is communicated with the main airflow passage 1111 through the ball valve 121, so that the dust and debris in the first cleaning device 3a can flow into the dust collecting space 21 through the first branch airflow passage 1121a, the ball valve 121 and the main airflow passage 1111.

[0088] Please refer to Figure 3 、 Figures 2 to 12 and Figure 2 When the dust collecting post 2 is required to store the dust and debris collected by the second cleaning device 3b, the ball valve 121 is rotated, and it is determined according to the detection result of the sensing assembly 13 whether the second branch airflow passage 1121b is communicated with the main airflow passage 1111 through the ball valve 121; if yes, the base station can be started; otherwise, the ball valve 121 is continuously rotated until the second branch airflow passage 1121b is communicated with the main airflow passage 1111 through the ball valve 121, so that the dust and debris in the second cleaning device 3b can flow into the dust collecting space 21 through the second branch airflow passage 1121b, the ball valve 121 and the main airflow passage 1111.

[0089] In some embodiments, the sensing assembly 13 comprises a plurality of sensors 131 and a moving piece 132, the sensors 131 are arranged on the pipeline assembly 11 and correspond to the branch airflow passages 1121 one by one, and the moving piece 132 is connected with the ball valve 121, when the ball valve 121 is rotated to make the branch airflow passages 1121 communicate with the main airflow passage 1111, at least part of the moving piece 132 moves to the sensing area of the sensor 131 corresponding to the branch airflow passage 1121 communicating with the main airflow passage 1111.

[0090] By adopting the above technical solution, the position of the moving piece 132 changes with the rotation of the ball valve 121, so that the position of the moving piece 132 can correspond to the position of the ball valve 121. When the ball valve 121 communicates the branch airflow passage 1121 and the main airflow passage 1111, the moving piece 132 can rotate with the ball valve 121 to the sensing area of the sensor 131 corresponding to the branch airflow passage 1121 communicating with the main airflow passage 1111. And each sensor 131 corresponds to a branch airflow passage 1121, so that the sensing assembly 13 can detect whether each branch airflow passage 1121 communicates with the main airflow passage 1111 through the ball valve 121, so as to improve the detection reliability of the sensing assembly 13.

[0093] In some embodiments, the physical signal that can be intuitively perceived by the user provided by the display is a pattern signal, and the display displays different visual information corresponding to the state of the branch airflow passage 1121. Taking the example that the branch airflow passage 1121 includes the first branch airflow passage 1121a and the second branch airflow passage 1121b, the display displays “both open” to indicate that the first branch airflow passage 1121a and the second branch airflow passage 1121b are both communicated with the main airflow passage 1111 through the ball valve 121; the display displays “first branch airflow passage 1121a open” to indicate that only the first branch airflow passage 1121a is communicated with the main airflow passage 1111 through the ball valve 121; and the display displays “second branch airflow passage 1121b open” to indicate that only the second branch airflow passage 1121b is communicated with the main airflow passage 1111 through the ball valve 121.

[0094] In other embodiments, the physical signal that can be intuitively perceived by the user provided by the display is a sound signal, and the display outputs different sentences corresponding to the state of the branch airflow passage 1121. Taking the example that the branch airflow passage 1121 includes the first branch airflow passage 1121a and the second branch airflow passage 1121b, the display outputs the sentence “both open” to indicate that the first branch airflow passage 1121a and the second branch airflow passage 1121b are both communicated with the main airflow passage 1111 through the ball valve 121; the display outputs the sentence “first branch airflow passage 1121a open” to indicate that only the first branch airflow passage 1121a is communicated with the main airflow passage 1111 through the ball valve 121; and the display outputs the sentence “second branch airflow passage 1121b open” to indicate that only the second branch airflow passage 1121b is communicated with the main airflow passage 1111 through the ball valve 121.
