DETAILED DESCRIPTION

[0053] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some structures related to the present application are shown in the accompanying drawings, rather than all structures. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0054] The terms "including" and "having" and any variations thereof in this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0055] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0056] See also Figure 1As shown, the cleaning system includes but is not limited to a sweeper, a scrubber, a vacuum cleaner, etc. Taking the cleaning system as a scrubber as an example, it usually includes a cleaning host 200 and a base station 300. The cleaning host 200 is mainly used to perform cleaning tasks. The cleaning host 200 includes a suction source 210 and a recycling box 220. The suction source 210 is a negative pressure generating structure such as a fan. Under the action of the suction source 210, negative pressure can be generated inside the recycling box 220 to suck out the dirt generated during the working process of the cleaning host 200; the base station 300 mainly provides cleaning liquid to the cleaning host 200, recovers and processes dirt, and stores and provides electricity to the cleaning host 200. A suction source 210 is usually also provided on the base station 300. When the cleaning host 200 and the base station 300 are docked, the suction source 210 on the base station 300 can form a negative pressure inside the base station 300 and recycle the dirt in the recycling box 220 into the base station 300.

[0057] However, with the above structure, a suction source 210 for applying suction force to the dirt needs to be provided on both the cleaning host 200 and the base station 300, which has a complex structure, high cost, and is not conducive to installation and maintenance.

[0058] Preferably, the utility model provides an air duct switching structure 100, which is used in the above-mentioned cleaning system, referring to Figures 2 to 5 As shown, the air duct switching structure 100 includes a first air duct 110 and a second air duct 120. The air duct switching structure 100 can selectively present the first air duct 110 or the second air duct 120. The first air duct 110 is suitable for connecting the suction source 210 and the recovery box 220 of the cleaning host 200, and the second air duct 120 is suitable for connecting the suction source 210 and the base station 300 of the cleaning host 200 when the cleaning host 200 and the base station 300 are docked.

[0059] When the cleaning host 200 performs a dirt suction task, the air duct switching structure 100 presents the first air duct 110, and the suction source 210 acts on the recovery box 220 to generate a negative pressure in the recovery box 220 and suck the dirt generated during the working process; when it is necessary to discharge the dirt in the recovery box 220, the cleaning host 200 is docked with the base station 300, the air duct switching structure 100 presents the second air duct 120, and the suction source 210 acts on the base station 300 to generate a negative pressure in the base station 300 and suck the dirt in the recovery box 220.

[0060] By setting up the air duct switching structure 100, a single suction source 210 can draw dirt into the recovery box 220, or draw dirt in the recovery box 220 into the base station 300, effectively reducing the production cost of the cleaning system, simplifying the structure of the cleaning system, and making assembly and maintenance more convenient.

[0061] Further, the air duct switching structure 100 can be arranged on the cleaning host 200 or the base station 300. Since the suction source 210 is located on the cleaning host 200, when the cleaning host 200 performs cleaning operations, it will be separated from the base station 300 and move freely. Preferably, in this embodiment, the air duct switching structure 100 is arranged on the cleaning host 200. Compared with being arranged on the base station 300, when the cleaning host 200 performs cleaning operations in this embodiment, the air duct switching structure 100 can reliably maintain the connection between the suction source 210 and the recovery box 220, and the air duct switching structure 100 will not restrict the movement of the cleaning host 200.

[0062] Further, the air duct switching structure 100 is a hollow structure, so as to form the first air duct 110 and the second air duct 120 therein. The air duct switching structure 100 has an axial direction and a radial direction, and the extension direction of the first air duct 110 and the second air duct 120 is the axial direction or the radial direction of the air duct switching structure 100. With the above structure, the first air duct 110 and / or the second air duct 120 has no bends or has fewer bends, and the circulation is smoother. In addition, the overall structure of the air duct switching structure 100 is compact, the installation space required is small, the adaptability is good, the air duct path is short, and the loss of the suction source 210 during operation is effectively reduced.

[0063] Preferably, the first air duct 110 and / or the second air duct 120 is bent at most once inside the air duct switching structure 100 .

[0064] Specifically, in one embodiment, the extension directions of the first air duct 110 and the second air duct 120 are both axial to the air duct switching structure 100 . At this time, the extension directions of the first air duct 110 and the second air duct 120 are parallel, and the first air duct 110 and the second air duct 120 have no bends inside the air duct switching structure 100 .

[0065] In another embodiment, the extension directions of the first air duct 110 and the second air duct 120 are both radial directions of the air duct switching structure 100 , and the extension directions of the first air duct 110 and the second air duct 120 are parallel. At this time, there are no bends in the first air duct 110 and the second air duct 120 inside the air duct switching structure 100 .

[0066] Preferably, in this embodiment, the extension direction of the first air duct 110 and the second air duct 120 are both radial directions of the air duct switching structure 100, and the first air duct 110 and / or the second air duct 120 are bent once inside the air duct switching structure 100. With the above structure, while ensuring smoothness of the circulation, the ends of the first air duct 110 and the second air duct 120 can be separated from each other, so that sufficient installation space can be provided between the first air duct 110 and the second air duct 120 to avoid the recycling box 220 and the base station 300 being limited to each other.

[0067] Further, the air duct switching structure 100 includes a housing 130 and a switching member 140. The housing 130 is a hollow structure. The switching member 140 is movably connected in the housing 130. The switching member 140 can move relative to the housing 130 to drive the housing 130 to present the first air duct 110 or the second air duct 120. The switching member 140 can use rotational motion and / or translational motion to achieve the switching of the air duct. In this embodiment, the switching member 140 is preferably rotatably connected to the housing 130. The switching member 140 drives the housing 130 to present the first air duct 110 or the second air duct 120 in response to the rotation operation, so as to facilitate the operation of the switching member 140 and simplify the connection structure between the switching member 140 and the housing 130. The switching member 140 can be driven by an electric drive member or a manual drive member, which is not limited by the present invention.

[0068] An air cavity 131 is formed in the housing 130. The housing 130 is provided with a first connection port 132, a second connection port 133, and a third connection port 134 that are connected to the air cavity 131. The first connection port 132 can be connected to the suction source 210, the second connection port 133 can be connected to the recovery box 220, and the third connection port 134 can be connected to the base station 300. The switching member 140 can close the second connection port 133 or the third connection port 134 in response to the rotation operation. When the third connection port 134 is closed, the first connection port 132 and the second connection port 133 are connected to form the first air duct 110. When the second connection port 133 is closed, the first connection port 132 and the third connection port 134 are connected to form the second air duct 120.

[0069] Furthermore, the axial direction of the air duct switching structure 100 is specifically the direction of the rotation axis of the switching member 140 , and the radial direction of the air duct switching structure 100 is specifically multiple directions perpendicular to the rotation axis of the switching member 140 .

[0070] When the extension direction of the first air duct 110 and the second air duct 120 are both in the axial direction of the air duct switching structure 100, the first connection port 132, the second connection port 133 and the third connection port 134 are all provided on the side wall of the housing 130 in the axial direction of the air duct switching structure 100. The first connection port 132 and the second connection port 133 are not staggered in the radial direction of the air duct switching structure 100, and the first connection port 132 and the third connection port 134 are not staggered in the radial direction of the air duct switching structure 100, thereby avoiding the existence of radial extension parts of the first air duct 110 and the second air duct 120, avoiding the existence of bends in the first air duct 110 and the second air duct 120, and being able to shorten the paths of the first air duct 110 and the second air duct 120, while the first connection port 132 and the second connection port 133 and the first connection port 132 and the third connection port 134 are far apart, thereby improving the installation adaptability of the air duct switching structure 100.

[0071] Preferably, the second connection port 133 and the third connection port 134 are located on the same side, and the first connection port 132 is located on the other side opposite to the second connection port 133 and / or the third connection port 134, so that the suction source 210 can be away from the recovery box 220 and the base station 300, reducing the probability of liquid adhering to the suction source 210 and reducing the risk of damage.

[0072] Further, when the extension directions of the first air duct 110 and the second air duct 120 are both radial directions of the air duct switching structure 100, the first connection port 132, the second connection port 133 and the third connection port 134 are all opened on the radial side wall of the housing 130 in the air duct switching structure 100. The first connection port 132, the second connection port 133 and the third connection port 134 are not staggered in the axial direction of the air duct switching structure 100, thereby avoiding the existence of axial extension parts in the first air duct 110 and the second air duct 120, and avoiding the existence of many bends in the first air duct 110 and the second air duct 120. The opening direction of at least one of the second connection port 133 and the third connection port 134 is parallel to the opening direction of the first connection port 132.

[0073] As a preferred embodiment, the opening direction of the second connection port 133 is parallel to the opening direction of the first connection port 132, the first air duct 110 has no bends inside the air duct switching structure 100, and the air duct path is short, so when the cleaning host 200 performs a cleaning operation, the suction source 210 can efficiently apply negative pressure to the recovery box 220, effectively improving the recovery efficiency of waste; the opening direction of the third connection port 134 is not parallel to the opening direction of the first connection port 132, that is, there is an angle between the opening directions of the third connection port 134 and the second connection port 133, which can drive the third connection port 134 and the second connection port 133 not to be close to each other, so as to provide sufficient space to adapt the recovery box 220 and the base station 300, so that when the base station 300 is docked with the third connection port 134, the recovery box 220 and the base station 300 are not limited, and the second air duct 120 is only bent once inside the air duct switching structure 100, so that the airflow is less obstructed during the circulation of the second air duct 120.

[0074] Further, as a preferred embodiment, referring to Figures 6 to 10 As shown, the air duct switching structure 100 further includes a docking member 150 fixedly connected to the housing 130, a third air duct 151 is formed in the docking member 150, one end of the third air duct 151 is connected to the second air duct 120, and the other end is formed with a docking port 152 for docking with the base station 300. The docking member 150 can be detachably fixed to the housing 130 by a threaded connector or a clamping structure, and one end of the third air duct 151 is connected to the second connection port 133.

[0075] By providing a docking piece 150 that is detachably connected to the housing 130, the adaptability of the air duct switching structure 100 can be improved, so that different docking pieces 150 can be replaced as needed to meet the docking requirements of different models of base stations 300, without having to adjust or replace the entire air duct switching structure 100, thereby reducing costs.

[0076] Preferably, the third air duct 151 extends in a direction away from the first air duct 110 , and the docking port 152 is located at the extended end of the third air duct 151 , thereby further increasing the distance between the docking port 152 and the second connection port 133 , further improving the adaptability of the cleaning host 200 and the base station 300 .

[0077] Preferably, the opening direction of the docking interface 152 is parallel to the docking direction of the air duct switching structure 100 and the base station 300. When the cleaning host 200 is docked with the base station 300, the docking interface 152 can be synchronously docked to the preset interface of the base station 300, reducing the operation steps and improving the user experience. In addition, when the cleaning host 200 is in the docking state, the docking interface 152 is preferably arranged downward, and is tightly pressed against the preset interface under the gravity of the cleaning host 200, thereby improving the tightness of the connection between the docking interface 152 and the preset interface.

[0078] Specifically, a pipe joint 310 is provided on the base station 300, and the pipe joint 310 is connected to the sewage pipeline 320 inside the base station 300. The pipe joint 310 includes a second plug-in portion 311 located outside the base station 300, and the docking piece 150 includes a first plug-in portion 153. The docking port 152 is formed on the first plug-in portion 153, and the second plug-in portion 311 is suitable for plugging and cooperating with the first plug-in portion 153 to conduct the pipe joint 310 and the docking port 152, so that the suction source 210 can act on the sewage pipeline 320 to suck the dirt in the recovery box 220 into the sewage pipeline 320.

[0079] The first plug-in portion 153 can be sleeved outside the second plug-in portion 311, or the first plug-in portion 153 can be inserted into the second plug-in portion 311 to achieve plug-in fit between the two.

[0080] In this embodiment, the first plug-in portion 153 is preferably inserted into the second plug-in portion 311. While satisfying the same circulation effect, the size of the first plug-in portion 153 can be made smaller, which is convenient for molding the first plug-in portion 153 on the docking piece 150, and can also avoid the first plug-in portion 153 affecting other plug-in structures adjacent to the second plug-in portion 311 after docking.

[0081] Preferably, the inner contour of the second plug-in portion 311 is non-circular to prevent fooling and ensure accurate docking of the second plug-in portion 311 and the first plug-in portion 153. The inner contour of the second plug-in portion 311 can be square or oval, etc., and is preferably oval in this embodiment. Correspondingly, the outer contour of the first plug-in portion 153 is also oval to improve the smoothness of circulation.

[0082] Preferably, a sealing structure 154 may be provided on the inner peripheral wall of the second plug-in portion 311 and / or the outer peripheral wall of the first plug-in portion 153 to improve the sealing performance therebetween, and the material of the sealing structure 154 includes but is not limited to rubber, silicone and plastic with a certain elasticity. In this embodiment, the sealing structure 154 is arranged around the outer peripheral wall of the first plug-in portion 153 to facilitate cleaning, and a plurality of sealing structures 154 may be arranged at intervals along the plug-in direction to improve the sealing effect.

[0083] Further, return Figure 1 As shown, the utility model also provides a cleaning device, including a cleaning host 200 and an air duct switching structure 100, and the air duct switching structure 100 is arranged on the cleaning host 200. Preferably, when the cleaning host 200 is in a cleaning state or a docking state, the first connecting port 132 is located above the second connecting port 133 and the third connecting port 134, thereby effectively reducing the probability of dirt flowing to the suction source 210 along with the suction airflow, and ensuring the normal operation of the suction source 210.
