[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] With the improvement of people's living standards and the increasing demand for clean living environments, cleaning equipment is being used more and more widely in daily life. In order to meet users' cleaning needs, this embodiment provides a cleaning device, which includes a base station, a first cleaning device, and a second cleaning device. Both the first and second cleaning devices can return to the base station and be charged through the base station so that they can continue cleaning next time.

[0035] In this embodiment, the first cleaning device is described using a cleaning robot as an example, and the second cleaning device is described using a handheld vacuum cleaner as an example. The cleaning robot includes at least a sweeping function, and may also include mopping functions.

[0036] To facilitate the collection of garbage, the cleaning robot is equipped with a dust box, and the handheld vacuum cleaner is also equipped with a dust box, so that garbage can be sucked in and temporarily stored during the cleaning process, thereby improving the continuity of the cleaning work.

[0037] To reduce the frequency of users emptying their trash, the base station is equipped with a dust collection bin, an air pump, and a three-ventilation duct structure. When the cleaning robot and handheld vacuum cleaner return to the base station, the three ducts of the three-ventilation duct structure connect to the dust collection bin, the dust box of the cleaning robot, and the dust box of the handheld vacuum cleaner, respectively. At this time, the air pump starts, sucking the trash from the dust boxes of the cleaning robot and the handheld vacuum cleaner into the base station's dust collection bin. Because the dust collection bin of the base station is relatively large, users can dispose of the trash in one go after multiple cleaning sessions, greatly reducing the cleaning workload for users.

[0038] However, if the cleaning robot is working or the user is using a handheld vacuum cleaner, the airflow in the other airflow will be reduced due to one air duct being open, making it impossible to suck the garbage in the dust box into the dust collection chamber, thus affecting garbage disposal.

[0039] like Figure 1 and Figure 2 As shown, to solve the above problems, the three-ventilation duct structure provided in this embodiment includes a duct assembly 1 and a switching assembly 2. The duct assembly 1 includes a connecting part 11 with a switching cavity 111, a main duct 12, a first sub-duct 13 and a second sub-duct 14 connected to the switching cavity 111. The main duct 12 is connected to the dust collection chamber, the first sub-duct 13 is connected to the dust box of the cleaning robot, and the second sub-duct 14 is connected to the dust box of the handheld vacuum cleaner. The switching assembly 2 includes a sealing switching member 21. The sealing switching member 21 is rotatably disposed in the switching cavity 111 to have a first position and a second position. When the sealing switching member 21 is in the first position, the sealing switching member 21 is in sealed contact with the first sub-duct 13. When the sealing switching member 21 is in the second position, the sealing switching member 21 is in sealed contact with the second sub-duct 14.

[0040] The sealing switch 21 can close the sub-duct corresponding to the cleaning device that is currently cleaning, as needed, to increase the airflow in the sub-duct corresponding to the cleaning device that needs to be cleaned. For example, when the user is using a handheld vacuum cleaner, the sealing switch 21 rotates to the second position, at which point the air pump starts and can suck the debris from the cleaning robot's dustbin into the dust collection chamber. When the user is using the cleaning robot, the sealing switch 21 rotates to the first position, at which point the air pump starts and can suck the debris from the handheld vacuum cleaner's dustbin into the dust collection chamber.

[0041] It is worth noting that if it is necessary to clean the dust box of the cleaning robot and the dust box of the handheld vacuum cleaner at the same time, the sealing switch 21 can be stopped at any position between the first position and the second position. At this time, the first sub-air duct 13 and the second sub-air duct 14 are both connected to the main air duct 12.

[0042] Understandably, since the sealing switching element 21 selects which sub-duct to close by rotating, the sealing side differs when the sealing switching element 21 closes different sub-ducts. If a single annular sealing structure is used to seal two sub-ducts, local deformation is likely to occur because the force directions of the sealing structure are frequently reversed. Figure 3 and Figure 4 As shown, in order to improve the sealing performance, the sealing switching component 21 includes a first sealing part 2122 and a second sealing part 2123 that are spaced apart. When the sealing switching component 21 is in the first position, the first sealing part 2122 is in sealing contact with the first sub-air duct 13. When the sealing switching component 21 is in the second position, the second sealing part 2123 is in sealing contact with the second sub-air duct 14.

[0043] The sealing switching component 21 is provided with a first sealing part 2122 for the first sub-air duct 13 and a second sealing part 2123 for the second sub-air duct 14, so that the sealing structure of the sealing switching component 21 for the two sub-air ducts does not affect each other. That is to say, the first sealing part 2122 and the second sealing part 2123 can play a sealing role respectively, thus avoiding the situation where the same sealing ring seals two sub-air ducts and the sealing is not tight, thereby improving the reliability of the three-air duct structure.

[0044] Furthermore, along the radially outward direction of the sealing switching member 21, the first sealing part 2122 is inclined away from the second sealing part 2123. This structure allows the first sealing part 2122 to open under the pressure between the first sub-duct 13 when sealing it, ensuring that the first sealing part 2122 can press against the end face of the first sub-duct 13 or the inner wall of the switching cavity 111 to close the first sub-duct 13.

[0045] Similarly, along the radial outward direction of the sealing switching member 21, the second sealing part 2123 is inclined away from the first sealing part 2122. This structure allows the second sealing part 2123 to open under the pressure between the two when sealing the second sub-duct 14, ensuring that the second sealing part 2123 can press against the end face of the second sub-duct 14 or the inner wall of the switching cavity 111 to close the second sub-duct 14.

[0046] In this embodiment, the outer diameter of the first sealing part 2122 is larger than the inner diameter of the first sub-air duct 13, and the outer diameter of the second sealing part 2123 is larger than the inner diameter of the second sub-air duct 14, so that both the first sealing part 2122 and the second sealing part 2123 can press against the inner wall of the switching cavity 111, ensuring the reliability of the seal and preventing the sealing switching member 21 from entering the first sub-air duct 13 or the second sub-air duct 14 due to excessive torque when rotating, thus causing the seal to fail.

[0047] In this embodiment, the switching assembly 2 further includes a drive component 22, and the sealing switching component 21 includes a rotating shaft 213, which passes through the air duct assembly 1 and is connected to the drive component 22 for transmission. The drive component 22 can provide power for the rotation of the sealing switching component 21 and pressure during sealing.

[0048] The switching cavity 111 is a spherical cavity with an inner diameter larger than that of the first sealing part 2122 and a diameter larger than that of the second sealing part 2123, ensuring that the sealing switching member 21 can rotate freely within the switching cavity 111.

[0049] Furthermore, the connection surface between the first sub-air duct 13 and the switching cavity 111 is the first sealing surface. When the sealing switching member 21 seals the first sub-air duct 13, the sealing ring line between the first sealing part 2122 and the switching cavity 111 is located on the first sealing surface. The connection surface between the second sub-air duct 14 and the switching cavity 111 is the second sealing surface. When the sealing switching member 21 seals the second sub-air duct 14, the sealing ring line between the second sealing part 2123 and the switching cavity 111 is located on the second sealing surface. The axis of the rotating shaft 213 is located on the intersection of the first sealing surface and the second sealing surface.

[0050] This structure, which makes the first sealing surface perpendicular to the axis of the first sub-duct 13 and the second sealing surface perpendicular to the axis of the second sub-duct 14, enables the pressure provided by the torque of the sealing switching element 21 to be perpendicular to the first sealing surface or the second sealing surface, which is equivalent to increasing the sealing pressure.

[0051] like Figures 3-5 As shown, the sealing switching component 21 includes a switching body 211 and a sealing kit 212. The switching body 211 is rotatably disposed in the switching cavity 111. The sealing kit 212 includes a fixing body 2121, which is fixedly connected to the switching body 211. The first sealing part 2122 and the second sealing part 2123 are disposed on the fixing body 2121.

[0052] By configuring the sealing switching component 21 into a separate switching body 211 and a sealing kit 212, the properties of different materials can be utilized to achieve normal use of the sealing switching component 21. The sealing kit 212 is made of a flexible material such as rubber, which can improve the sealing performance through its own deformation. The switching body 211 is made of a rigid material such as plastic or metal, which plays a supporting role, provides sufficient pressure for the sealing kit 212, and at the same time limits the deformation of the sealing kit 212 to ensure the sealing effect.

[0053] Furthermore, the fixing body 2121 is provided with a fixing groove 2124, and the switching body 211 is disposed in the fixing groove 2124. This structure can not only improve the reliability of the connection between the fixing body 2121 and the switching body 211, but also enable the first sealing part 2122 and the second sealing part 2123 to be located on the outer periphery of the sealing switching member 21, which facilitates sealing.

[0054] Furthermore, the fixed body 2121 is provided with a plurality of insertion slots 2111, and the switching body 211 is provided with insertion parts 2125 corresponding to the plurality of insertion slots 2111 one by one. The insertion parts 2125 are inserted and engaged with the corresponding insertion slots 2111, thereby further improving the reliability of the connection between the fixed body 2121 and the switching body 211, improving the support of the switching body 211 for the fixed body 2121, and preventing relative movement between the switching body 211 and the fixed body 2121.

[0055] In some embodiments, the switching body 211 is provided with a plurality of insertion slots 2111, and the fixing body 2121 is provided with insertion portions 2125 corresponding to the plurality of insertion slots 2111 one by one. The insertion portions 2125 are inserted and engaged with the corresponding insertion slots 2111, which can improve the reliability of the connection between the fixing body 2121 and the switching body 211, improve the support of the switching body 211 for the fixing body 2121, and prevent relative movement between the switching body 211 and the fixing body 2121.

[0056] In this embodiment, to prevent the switching body 211 from detaching from the fixing body 2121, the switching body 211 and the fixing body 2121 are fixed together by adhesive bonding.

[0057] like Figure 1 and Figure 2 As shown, for ease of installation, the duct assembly 1 includes a first housing 15 and a second housing 16, which are detachably connected. That is, after the switching assembly 2 is installed into the first housing 15 or the second housing 16, the first housing 15 and the second housing 16 can be fastened and fixed.

[0058] Furthermore, the first housing 15 is provided with a sealing groove 161, and a sealing strip is provided in the sealing groove 161. The second housing 16 is provided with a sealing protrusion, which can be inserted into the sealing groove 161 and squeeze the sealing strip. The sealing protrusion squeezing the sealing strip can improve the sealing performance between the first housing 15 and the second housing 16, thereby preventing air leakage from the gap between the air duct assembly 1 and the second housing 16.

[0059] Similarly, in some embodiments, the second housing 16 is provided with a sealing groove 161, and a sealing strip is provided in the sealing groove 161. The first housing 15 is provided with a sealing protrusion, which can be inserted into the sealing groove 161 and squeeze the sealing strip, thus also improving the sealing performance.

[0060] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
