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.

[0046] 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.

[0047] 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.

[0048] See also Figure 1 and Figure 2 As shown, a cleaning device 100 corresponding to a preferred embodiment of the present invention is used for cleaning operations. The cleaning device 100 includes but is not limited to a floor scrubber, a floor sweeper, and a vacuum cleaner, etc., and the following will mainly describe the cleaning device 100 as a floor scrubber as the main scenario.

[0049] The cleaning device 100 includes a cleaning main body 110, which includes a main body 113 and a floor brush 114 connected to the main body 113. A suction device 111 and a recovery container 112 are provided on the main body 113. The suction device 111 can act on the recovery container 112 to suck the dirt generated during the cleaning process of the floor brush 114 into the recovery container 112. The recovery container 112 can be directly formed on the main body 113, or be a box structure detachably connected to the main body 113, which is not limited by the present invention.

[0050] Preferably, the cleaning device 100 further includes a switching structure 120, referring to Figure 3 and Figure 6 As shown, the switching structure 120 includes a first air inlet 1211, a second air inlet 1212 and an air outlet 1213, and the air outlet 1213 can be selectively connected to the first air inlet 1211 and / or the second air inlet 1212. The suction device 111 is suitable for docking with the air outlet 1213, the recovery container 112 is suitable for docking with the first air inlet 1211, and the second air inlet 1212 is suitable for being connected to an external device. In this embodiment, the external device specifically refers to the base station 200. Of course, in other embodiments, the external device can also be other devices that require negative pressure.

[0051] The utility model sets a switching structure 120. During normal cleaning operations, the suction device 111 can act on the recovery container 112 through the air outlet 1213 and the first air inlet 1211, so that the dirt in the cleaning process can be sucked into the recovery container 112; when performing a dirt recovery operation, the cleaning device 100 is connected to an external device, so that the second air inlet 1212 is connected to the external device, and the suction device 111 can act on the external device through the air outlet 1213 and the second air inlet 1212 to recover the dirt in the recovery container 112 to the external device; a single suction device 111 can realize the suction of dirt into the recovery container 112, or the extraction of dirt from the recovery container 112, which effectively reduces the production cost of the cleaning system, simplifies the structure of the cleaning system, and is more convenient to assemble and maintain.

[0052] Furthermore, a first docking port 1151 communicating with the second air inlet 1212 is provided on the cleaning host 110 . The first docking port 1151 is located outside the cleaning host 110 and is suitable for docking with an external device.

[0053] Specifically, refer to Figure 4 and Figure 7 As shown, a first docking member 115 is provided on the cleaning host 110, and the first docking member 115 includes a first end 1152 and a second end 1153 which are connected to each other, and a first flow channel 1154 is formed between the first end 1152 and the second end 1153, the first end 1152 is docked with the second air inlet 1212, and the first docking port 1151 is formed at the second end 1153.

[0054] Of course, in other embodiments, the first docking member 115 may also be disposed on the switching structure 120, and the first docking port 1151 is formed on the switching structure 120. However, compared with disposing the first docking port 1151 on the switching structure 120, it is obviously more in line with conventional usage habits to dispose the first docking port 1151 on the cleaning host 110.

[0055] Furthermore, in one embodiment, the switching structure 120 and the cleaning host 110 can be separately provided, and the two are connected through an air pipe (not shown), and the switching structure 120 may not move synchronously with the cleaning host 110 during the cleaning process to reduce the weight on the cleaning host 110. However, with the above structure, the cleaning host 110 is inconvenient to move and store due to the air pipe, and the air flow path between the two is long, which is not conducive to the efficient operation of the suction device 111.

[0056] Preferably, in this embodiment, the switching structure 120 is disposed on the cleaning host 110 and is located between the suction device 111 and the recovery container 112. The suction device 111 and the recovery container 112 are directly connected to the switching structure 120, thereby avoiding the need to add an air pipe, facilitating the movement and storage of the cleaning host 110, and effectively reducing the flow path of the airflow, thereby improving the working performance of the suction device 111. At this time, the first docking port 1151 can be formed on the cleaning host 110 or the switching structure 120, and the utility model is not limited thereto.

[0057] Preferably, the first docking member 115 is detachably connected to the cleaning host 110 and / or the switching structure 120, so that different types of first docking members 115 can be replaced as needed to improve the adaptability of docking with different external devices.

[0058] Further, refer to Figure 3 and Figure 6 As shown, the switching structure 120 includes a switching body 121 and a switching member 122 movably connected to the switching body 121. The switching body 121 is a hollow structure, and a wind cavity 1214 is formed inside it. The first air inlet 1211, the second air inlet 1212 and the air outlet 1213 are all provided on the switching body 121 and communicated with the wind cavity 1214. The first air inlet 1211 and the second air inlet 1212 are both located on the movement path of the switching member 122.

[0059] The switching member 122 is adapted to move to different preset positions under the drive of external force to block the first air inlet 1211 or the second air inlet 1212, so that the suction force of the suction device 111 can act entirely on the recovery container 112 or entirely on the external device as required, thereby improving the suction effect. Preferably, the switching member 122 can also be moved to other preset positions so that the first air inlet 1211 and the second air inlet 1212 are at least partially opened at the same time, at which time both the recovery container 112 and the external device can operate, thereby improving the cleaning efficiency and adapting to different usage requirements.

[0060] Furthermore, the switching member 122 can be driven by an electric drive member or a manual drive member, which is not limited in the present invention. In addition, the switching member 122 can be arranged in the air cavity 1214 or outside the air cavity 1214 according to actual needs. In this embodiment, the switching member 122 is preferably arranged in the air cavity 1214 to reduce the overall volume of the switching structure 120, avoid the switching member 122 from being disturbed by the outside world, and improve the reliability of the switching.

[0061] The active connection between the switching member 122 and the switching body 121 may include a variety of motion modes, for example, the switching member 122 may reciprocate linearly relative to the switching body 121, or may rotate relative to the switching body 121, or a combination of the two motion modes.

[0062] When the switching member 122 reciprocates linearly relative to the switching body 121, at least part of the inner wall of the air cavity 1214 is a plane, and the switching member 122 is in close contact with the plane. The first air inlet 1211 and the second air inlet 1212 are arranged on the plane at intervals along the movement direction of the switching member 122 to facilitate opening or closing of the air inlet during the movement of the switching member 122.

[0063] Preferably, the first air inlet 1211 and the air outlet 1213 are located on an extension line of the same straight line, and / or the second air inlet 1212 and the air outlet 1213 are located on an extension line of the same straight line, so as to reduce the bending of the airflow in the flow path and improve the smoothness of the airflow.

[0064] However, the linear reciprocating method is used, and it is inconvenient to adjust the state of the switching member 122. A slide rail structure needs to be set between the switching member 122 and the switching body 121. The space required for installation is large, the structure is complex, and the switching member 122 requires a large movement space, which makes it difficult to reduce the volume of the switching body 121 and meet the mainstream market demand.

[0065] Preferably, in this embodiment, the switching member 122 is rotatably connected to the switching body 121, so as to reduce the volume of the switching body 121 and make state adjustment more convenient and controllable.

[0066] Specifically, in one embodiment, referring to Figures 3 to 5 As shown, the switching member 122 includes a shaft portion 1221 and a shielding portion 1222. The shaft portion 1221 is rotatably disposed on the switching body 121 and is at least partially located in the wind cavity 1214. The shielding portion 1222 is accommodated in the wind cavity 1214 and is fixedly connected to the shaft portion 1221. The shaft portion 1221 is suitable for rotating under the action of an external force and driving the shielding portion 1222 to rotate, thereby realizing the opening and closing of the air inlet.

[0067] Preferably, at least part of the inner wall of the wind cavity 1214 is an arc-shaped surface, the first air inlet 1211 and the second air inlet 1212 are both located on the arc-shaped surface, and the shielding portion 1222 is suitable for fitting in contact with the arc-shaped surface and can move along the arc-shaped surface to improve the smoothness of the movement of the switching member 122 and the reliability of opening and closing the air inlet.

[0068] In another embodiment, referring to Figures 6 to 8As shown, at least part of the outer circumference of the switching member 122 is circular, and the inner circumference of the corresponding part of the air cavity 1214 is also circular. After the switching member 122 is installed in the air cavity 1214, the outer circumferential wall of the switching member 122 is in close contact with the inner circumferential wall of the air cavity 1214, and the switching member 122 can rotate under the guidance of the inner circumferential wall of the air cavity 1214. With the above structure, when installing the switching member 122, it only needs to be directly installed in the air cavity 1214, and there is no need to set an additional rotating connection structure between the two, which further simplifies the overall structure.

[0069] Preferably, the switching member 122 is specifically a cylindrical structure, and each cross section of the inner contour of the air cavity 1214 is circular, thereby increasing the contact area between the outer circumferential wall of the switching member 122 and the inner circumferential wall of the air cavity 1214, and making the installation and rotation reliability of the switching member 122 better. The cross-sectional dimensions of the inner contour of the air cavity 1214 are preferably the same, so as to facilitate the molding of the air cavity 1214 and the switching member 122.

[0070] The cylindrical switching member 122 has a closed inner cavity, and a plurality of openings 1223 connected to the inner cavity are provided on the outer wall of the switching member 122. During the rotation process, the outer wall of the switching member 122 can block the air inlet and / or the air outlet 1213, while the openings 1223 can realize the opening of the air inlet and / or the air outlet 1213.

[0071] For example, during the rotation of the switching member 122, when the outer wall of the switching member 122 blocks the first air inlet 1211, the opening 1223 corresponds to the second air inlet 1212 and the air outlet 1213, and the second air inlet 1212 and the air outlet 1213 are connected through the inner cavity of the switching member 122; or, when the outer wall of the switching member 122 blocks the second air inlet 1212, the opening 1223 corresponds to the first air inlet 1211 and the air outlet 1213, and the first air inlet 1211 and the air outlet 1213 are connected through the inner cavity of the switching member 122.

[0072] Further, the switching body 121 has an axial direction and a radial direction, the axial direction of the switching body 121 is the direction of the rotation axis of the switching member 122, and the radial direction of the switching body 121 is a plurality of directions perpendicular to the direction of the rotation axis of the switching member 122. There are many situations for the position setting of the first air inlet 1211, the second air inlet 1212 and the air outlet 1213, which will be described in detail below.

[0073] In one case, the first air inlet 1211 , the second air inlet 1212 and the air outlet 1213 are all located on the radial side wall of the switching body 121 , so as to open and close the first air inlet 1211 and the second air inlet 1212 during the rotation of the switching member 122 .

[0074] Specifically, in one embodiment, referring to Figure 3As shown, the first air inlet 1211, the second air inlet 1212 and the air outlet 1213 can be arranged in an axial direction without being staggered with respect to the switching body 121, that is, the three are located on the same circumferential surface, thereby avoiding the existence of axial extension parts in the flow path formed between the first air inlet 1211 and the air outlet 1213, and the flow path formed between the second air inlet 1212 and the air outlet 1213, thereby effectively reducing the bending of the flow path and the flow path, improving the suction efficiency, and making the switching body 121 more compact in the axial direction, which is conducive to reducing the volume of the switching body 121.

[0075] The air outlet 1213 and at least one of the first air inlet 1211 and the second air inlet 1212 are located on an extension line of the same straight line, so as to further reduce the flow path and the bending of the flow path.

[0076] Preferably, the first air inlet 1211 and the air outlet 1213 are located on the extension line of the same straight line, so that when the cleaning host 110 performs a cleaning operation, the suction device 111 can efficiently apply negative pressure to the recovery container 112, thereby effectively improving the recovery efficiency of waste; the second air inlet 1212 and the air outlet 1213 are not located on the extension line of the same straight line, which can drive the first air inlet 1211 and the second air inlet 1212 not to be close to each other, thereby providing sufficient space to adapt the recovery container 112 and external equipment, so that when docking with the external equipment, the recovery container 112 and the external equipment will not limit each other, and the flow path between the second air inlet 1212 and the air outlet 1213 is only bent once inside the switching body 121, so that there is less obstruction during the air flow process.

[0077] Indeed, in another embodiment, referring to Figure 6 As shown, at least two of the first air inlet 1211, the second air inlet 1212 and the air outlet 1213 may also be staggered in the axial direction of the switching body 121, that is, at least two of the first air inlet 1211, the second air inlet 1212 and the air outlet 1213 are not located on the same circumferential surface, so as to provide a larger installation space for installing the suction device 111, the recovery container 112 and external equipment, thereby further improving versatility.

[0078] Preferably, the first air inlet 1211 and the air outlet 1213 are not staggered in the axial direction of the switching body 121, that is, the two are located on the same circumferential surface, so as to avoid the existence of an axial extension part and excessive bends in the flow path between the first air inlet 1211 and the air outlet 1213, shorten the flow path, and make the air flow smoother, thereby ensuring the cleaning effect of the cleaning host 110. The first air inlet 1211 and the air outlet 1213 can be located on the extension line of the same straight line, in which case the flow path between the first air inlet 1211 and the air outlet 1213 will have no bends, and the air flow and suction efficiency will be in the best state.

[0079] The second air inlet 1212 and the air outlet 1213 are staggered in the axial direction of the switching body 121, that is, the second air inlet 1212 and the air outlet 1213 have a large spacing in the axial direction of the switching body 121, which can avoid the recovery container 112 and the external equipment from limiting each other, so as to adapt to more models of recovery containers 112 and external equipment and improve versatility.

[0080] Furthermore, in another case, the first air inlet 1211, the second air inlet 1212 and the air outlet 1213 are all located on the axial end wall of the switching body 121, and are not staggered in the radial direction of the switching body 121. With such a design, the flow path between the first air inlet 1211 and the air outlet 1213 and the flow path between the second air inlet 1212 and the air outlet 1213 have no radial bends, thereby improving the smoothness of airflow.

[0081] Preferably, the first air inlet 1211 and the second air inlet 1212 are located on the same side, and the air outlet 1213 is located on the other side opposite to the first air inlet 1211 and / or the second air inlet 1212, so that the suction device 111 can be kept away from the recovery container 112 and external equipment, reducing the probability of liquid adhering to the suction device 111 and reducing the risk of damage.

[0082] Further, refer to Figure 1 As shown, the utility model also provides a cleaning system, including a base station 200, a cleaning device 100 and a switching structure 120, the cleaning device 100 includes a cleaning host 110, the cleaning host 110 includes a suction device 111 and a recovery container 112, the switching structure 120 includes a first air inlet 1211, a second air inlet 1212 and an air outlet 1213, the air outlet 1213 can be selectively connected to the first air inlet 1211 and / or the second air inlet 1212, the suction device 111 is docked with the air outlet 1213, the recovery container 112 is docked with the first air inlet 1211, and when the base station 200 and the cleaning device 100 are docked, the second air inlet 1212 is suitable for being connected with the base station 200, so that the suction device 111 can act on the recovery container 112 and / or the base station 200 as needed.

[0083] Further, refer to Figure 2 , Figures 9 to 11As shown, a sewage extraction pipeline 210 is provided inside the base station 200, and the input end of the sewage extraction pipeline 210 can be connected to the recovery container 112, and the output end of the sewage extraction pipeline 210 can be selectively connected to the sewage collection container 220, or directly connected to the external sewage discharge pipeline. When the base station 200 is provided with the sewage collection container 220, it is convenient for the base station 200 to temporarily store sewage, thereby improving the installation adaptability of the base station 200; when the base station 200 is not provided with the sewage collection container 220, the sewage extraction pipeline 210 extends out of the base station 200 to connect to the external sewage discharge pipeline, and the sewage sucked into the base station 200 can be automatically discharged to the external sewage discharge pipeline, thereby avoiding manual dumping of sewage and improving the user experience.

[0084] In addition, the base station 200 also includes a second docking interface 231 that is connected to the sewage extraction pipeline 210 and / or the sewage collecting container 220 and is used to connect to the first docking interface 1151. When the cleaning equipment 100 is docked to the base station 200, the first docking interface 1151 is connected to the second docking interface 231, and the sewage extraction pipeline 210 is connected to the recovery container 112.
