DETAILED DESCRIPTION

[0051] In order to make the above-mentioned objects, 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 will 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, rather than all, structures related to the present application are shown in the accompanying drawings. 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.

[0052] As used herein, the terms "comprise," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0053] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0054] 1 and 2 illustrate a preferred embodiment of a cleaning device 100 of the present disclosure, which 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. The following description will primarily focus on the floor scrubber as the primary scenario.

[0055] The cleaning device 100 includes a cleaning main unit 110, which includes a main unit 113 and a floor brush 114 connected to the main unit 113. The main unit 113 is provided with a suction device 111 and a recovery container 112. 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 unit 113, or can be a box structure detachably connected to the main unit 113, which is not limited in this disclosure.

[0056] Preferably, the cleaning device 100 further includes a switching structure 120. Referring to Figures 3 and 6, 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 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 connecting with 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.

[0057] The present disclosure 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 docked 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, thereby effectively reducing the production cost of the cleaning system, simplifying the structure of the cleaning system, and making assembly and maintenance more convenient.

[0058] Furthermore, the cleaning host 110 is provided with a first docking port 1151 that is in communication with the second air inlet 1212 . The first docking port 1151 is located outside the cleaning host 110 and is suitable for docking with an external device.

[0059] Specifically, referring to Figures 4 and 7, 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 that 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.

[0060] Of course, in other embodiments, the first docking member 115 may also be disposed on the switching structure 120, in which case the first docking port 1151 is formed on the switching structure 120. However, compared to disposing the first docking port 1151 on the switching structure 120, disposing the first docking port 1151 on the cleaning host 110 is obviously more in line with conventional usage habits.

[0061] Furthermore, in one embodiment, the switching structure 120 and the cleaning main unit 110 can be provided separately and connected by an air pipe (not shown). During the cleaning process, the switching structure 120 does not need to move synchronously with the cleaning main unit 110 to reduce the weight of the cleaning main unit 110. However, with the above structure, the cleaning main unit 110 is relatively inconvenient to move and store due to the air pipe. At the same time, the air flow path between the two is long, which is not conducive to the efficient operation of the suction device 111.

[0062] Preferably, in this embodiment, the switching structure 120 is provided on the cleaning main unit 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 for an additional air pipe, facilitating the movement and storage of the cleaning main unit 110, and effectively reducing the airflow path, thereby improving the working performance of the suction device 111. In this case, the first docking port 1151 can be formed on the cleaning main unit 110 or the switching structure 120, and this disclosure is not limited thereto.

[0063] 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.

[0064] 3 and 6 , 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 having an air cavity 1214 formed therein. A first air inlet 1211, a second air inlet 1212, and an air outlet 1213 are all provided on the switching body 121 and communicate with the air 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.

[0065] The switching member 122 is adapted to be moved to different preset positions under external force to block the first air inlet 1211 or the second air inlet 1212, allowing the suction force of the suction device 111 to be fully applied to the recovery container 112 or to the external device as needed, thereby improving the suction effect. Preferably, the switching member 122 can also be moved to other preset positions to simultaneously at least partially open the first air inlet 1211 and the second air inlet 1212. In this case, both the recovery container 112 and the external device can operate, thereby improving cleaning efficiency and adapting to different usage requirements.

[0066] Furthermore, the switching member 122 can be driven by an electric drive member or a manual drive member, which is not limited in this disclosure. Furthermore, the switching member 122 can be disposed within or outside the air cavity 1214 as needed. In this embodiment, the switching member 122 is preferably disposed within the air cavity 1214 to reduce the overall volume of the switching structure 120, prevent the switching member 122 from being affected by external interference, and improve switching reliability.

[0067] The movable connection between the switching member 122 and the switching body 121 can include multiple motion modes, for example, the switching member 122 can reciprocate linearly relative to the switching body 121, or can rotate relative to the switching body 121, or a combination of the two motion modes.

[0068] 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 contact with the plane. The first air inlet 1211 and the second air inlet 1212 are arranged at intervals on the plane along the movement direction of the switching member 122 to facilitate opening or closing the air inlet during the movement of the switching member 122.

[0069] 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.

[0070] However, the linear reciprocating method makes it 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 installation space is large and the structure is complex. In addition, 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.

[0071] 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.

[0072] Specifically, in one embodiment, referring to Figures 3 to 5, the switching member 122 includes a shaft 1221 and a shielding portion 1222. The shaft 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 1221. The shaft 1221 is suitable for rotating under the action of external force and driving the shielding portion 1222 to rotate, thereby realizing the opening and closing of the air inlet.

[0073] Preferably, at least part of the inner wall of the air 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 and contacting 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 the opening and closing of the air inlet.

[0074] In another embodiment, as shown in Figures 6 to 8 , at least a portion of the outer circumference of the switching member 122 is circular, and the inner circumference of the corresponding portion 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 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 this structure, when installing the switching member 122, it only needs to be directly installed into the air cavity 1214, without the need for an additional rotating connection structure between the two, further simplifying the overall structure.

[0075] Preferably, the switching member 122 is cylindrical in structure, and each cross-section of the inner contour of the air cavity 1214 is circular. This increases the contact area between the outer circumferential wall of the switching member 122 and the inner circumferential wall of the air cavity 1214, thereby improving the reliability of the installation and rotation of the switching member 122. The cross-sections of the inner contour of the air cavity 1214 are preferably of the same size to facilitate the molding of the air cavity 1214 and the switching member 122.

[0076] The cylindrical switching member 122 has a sealed 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.

[0077] 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.

[0078] Furthermore, 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. The positions of the first air inlet 1211, the second air inlet 1212, and the air outlet 1213 can be arranged in various ways, which will be described in detail below.

[0079] 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 .

[0080] Specifically, in one embodiment, as shown in Figure 3, the first air inlet 1211, the second air inlet 1212 and the air outlet 1213 may not be staggered in the axial direction of the switching body 121, that is, the three are located on the same circumferential surface, 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, effectively reducing the flow path and the bending of 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.

[0081] 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.

[0082] 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 efficiency of waste recovery; 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 to be not close to each other, so as to provide sufficient space to adapt the recovery container 112 and the external device, so that when the external device is docked, the recovery container 112 and the external device 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 the air flow is less obstructed during the circulation process.

[0083] Indeed, in another embodiment, as shown in Figure 6, at least two of the first air inlet 1211, the second air inlet 1212 and the air outlet 1213 can 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.

[0084] Preferably, the first air inlet 1211 and the air outlet 1213 are not staggered axially with respect to the switching body 121, that is, they are located on the same circumferential surface. This avoids axial extension and excessive bends in the flow path between the first air inlet 1211 and the air outlet 1213. This shortens the flow path while ensuring smoother airflow, thereby ensuring the cleaning effect of the cleaning main unit 110. The first air inlet 1211 and the air outlet 1213 can be located on an extension of the same straight line. In this case, the flow path between the first air inlet 1211 and the air outlet 1213 is free of bends, achieving optimal airflow and suction efficiency.

[0085] 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.

[0086] 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 the airflow.

[0087] 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 chance of liquid adhering to the suction device 111 and reducing the risk of damage.

[0088] Further, as shown in Figure 1, the present disclosure 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.

[0089] Furthermore, referring to Figures 2 and 9 to 11, a sewage extraction pipeline 210 is provided inside the base station 200. 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 a sewage collection container 220, or directly connected to an external sewage pipe. When the base station 200 is provided with a 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 a sewage collection container 220, the sewage extraction pipeline 210 extends out of the base station 200 to connect to an external sewage pipe. The sewage sucked into the base station 200 can be automatically discharged to the external sewage pipe, thereby avoiding manual dumping of sewage and improving the user experience.

[0090] 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. The suction device 111 can act on the sewage collecting container 220 and / or the sewage extraction pipeline 210 through the air outlet 1213, the second air inlet 1212, the first docking interface 1151 and the second docking interface 231, so that the sewage collecting container 220 and / or the sewage extraction pipeline 210 generate negative pressure. Under the action of the negative pressure, the dirt in the recovery container 112 is collected and concentrated in the sewage collecting container 220, or enters the sewage pipe along the sewage extraction pipeline 210.

[0091] Specifically, a second docking piece 230 and a suction duct 240 are provided on the base station 200. The second docking piece 230 includes a third end 232 and a fourth end 233 that are connected to each other. A second flow channel 234 is formed between the third end 232 and the fourth end 233. The third end 232 is located outside the base station 200 and is formed with a second docking port 231. The fourth end 233 is located inside the base station 200 and is connected to the suction duct 240. The suction duct 240 is suitable for being connected to the sewage extraction pipeline 210 and / or the sewage collecting container 220, so that the suction device 111 provides negative pressure to the sewage collecting container 220 or the sewage extraction pipeline 210 to extract the dirt in the recovery container 112.

[0092] Preferably, the opening direction of the first docking interface 1151 is parallel to the docking direction of the switching structure 120 and the base station 200. When the cleaning device 100 is docked with the base station 200, the first docking interface 1151 can be synchronously docked to the second docking interface 231, reducing the operation steps and improving the user experience.

[0093] In addition, when the cleaning device 100 is in the docking state, the first docking port 1151 is preferably arranged downward, and the second docking port 231 is preferably arranged upward, so that under the action of the gravity of the cleaning device 100, the first docking port 1151 and the second docking port 231 can be tightly abutted against each other, thereby improving the tightness of the connection between the two. The first docking port 1151 and the second docking port 231 can be connected by plugging, snapping, etc., which is not limited in this disclosure, and a sealing structure can also be provided between the two to improve the sealing effect after docking.
