Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0019] The base station provided in this application can be used for various household appliances with cleaning systems, such as floor scrubbers and kitchen appliances. It is not limited whether the cleaning system has a host. That is, the cleaning system can include a base station and a host, or it can only include a base station. The following will take the base station used in a cleaning system with a host as an example for introduction.

[0020] This application first proposes a base station of a cleaning system, such as Figures 1 to 6 As shown, Figure 1 This is a structural diagram of an embodiment of a base station of the present application; Figure 2 yes Figure 1 A schematic side view of an embodiment;

[0021] Figure 3 yes Figure 1 A schematic cross-sectional view of an embodiment; Figure 4 yes Figure 1 A schematic cross-sectional view of a portion of the structure of an embodiment; Figure 5 yes Figure 1 A schematic top view of an embodiment; Figure 6 The figure is a schematic structural diagram of an embodiment of a volute in a base station of the present application. The base station includes a volute 10 and a first fan. A first inlet 101 of the volute 10 is used to input waste, and a first outlet 102 of the volute 10 serves as a sewage outlet for the base station. The first fan includes a first impeller 20 and a wet / dry motor 30. The first impeller 20 is disposed within the volute 10. A drive shaft 31 of the wet / dry motor 30 extends into the volute 10 and is in transmission connection with the first impeller 20 to drive the first impeller 20 to rotate. The drive shaft 31 is sealed and rotatably connected to the volute 10. When the wet / dry motor 30 drives the first impeller 20 to operate, waste enters the volute 10, which serves as a sewage collection chamber, through the first inlet 101. The waste within the volute is then sucked into the first impeller 20 and stirred by the first impeller 20 to be discharged through the sewage outlet.

[0022] When the first impeller 20 is working, it can generate negative pressure in the volute 10, and can suck the dirt in the host into the volute 10 through the first inlet 101 of the volute. The dirt in the volute 10 is sucked into the first impeller 20 and stirred by the first impeller 20 to the sewage outlet (i.e., the first outlet 102) of the base station for discharge.

[0023] In some embodiments, the cleaning system includes a sweeping machine system, a washing machine system, a washing and drying machine system, a sweeping and mopping machine system, etc., without specific limitation. Among them, the host includes a cleaning device for cleaning the surface or object to be cleaned, such as a washing machine, a sweeping machine, etc. The dirt in the host can be a liquid such as sewage, a solid such as dust or debris, or a solid-liquid mixture formed by a mixture of particulate matter and sewage, etc., without specific limitation; in some application scenarios, the base station can charge the host or clean or dry at least some components of the host, such as a washing machine base station, a sweeping machine base station, etc., which can charge cleaning equipment such as washing machines and sweeping machines. For example, the washing machine base station can clean and dry the cleaning cloth on the washing machine host, etc., without specific limitation.

[0024] In some embodiments, multiple hosts may share the same base station, and the hosts include a sweeper, a floor scrubber, a dryer-washer, a sweeper-mop, etc., without specific limitation.

[0025] In one application scenario, the host is physically docked with the base station, and the sewage outlet of the host and the first inlet 101 of the volute 10 can be in corresponding positions. When the wet and dry dual-purpose motor 30 drives the first impeller 20 to work, negative pressure is generated in the volute 10. Under the action of the negative pressure, the sewage outlet of the host and the first inlet 101 are connected. Under the action of the negative pressure, the dirt in the host enters the volute 10 through the sewage outlet of the host and the first inlet 101. The dirt in the volute 10 is sucked into the first impeller 20 and stirred by the first impeller 20 to the sewage outlet of the base station (i.e., the first outlet 102) and discharged to the external environment. For example, the first outlet 102 can be used to connect to the drainage system in the environment to discharge the dirt into the external environment such as the sewer.

[0026] The wet / dry motor 30 is a specially designed motor that can operate stably in both dry and wet environments. This motor is typically well sealed and waterproof and dustproof, preventing moisture and dust from entering the motor, thereby ensuring normal operation and extending its service life.

[0027] The wet and dry dual-purpose motor 30 is applied to the cleaning system, so that the cleaning system can adapt to a variety of working environments. For example, when the wet and dry dual-purpose motor is applied to a smart home cleaning system, the practicality of the cleaning system in multiple scenarios can be improved in working environments with high humidity such as kitchens and bathrooms, as well as in relatively dry working environments such as living rooms and bedrooms, so that the cleaning system can provide more comprehensive cleaning services.

[0028] The beneficial effect of the above-mentioned arrangement is that the first impeller 20 is arranged in the volute 10, and negative pressure can be generated in the volute 10 during operation, so that the dirt enters the volute 10 serving as a sewage collecting chamber through the first inlet 101 under the action of negative pressure. The dirt in the volute 10 is sucked into the first impeller 20 and stirred by the first impeller 20 to be discharged to the sewage outlet of the base station. Therefore, there is no need to set up a special sewage collecting chamber, which can simplify the sewage discharge structure of the base station, facilitate the miniaturization of the base station, and improve the user experience; further, the setting of the wet and dry dual-purpose motor 30 facilitates automatic sewage discharge, and the wet and dry dual-purpose motor 30 can work stably in dry and wet environments, which can improve the multi-scenario practicality of the base station and improve the user's convenience; the drive shaft 31 is sealed and connected to the volute 10 and can be rotatably arranged, which can improve the position stability of the wet and dry dual-purpose motor 30 during operation and improve reliability.

[0029] In some embodiments, see Figure 4 A mounting groove 103 is provided on the side of the volute 10 close to the wet and dry dual-purpose motor 30, and a mounting through-hole 104 is provided at the bottom of the mounting groove 103. The drive shaft 31 passes through the mounting groove 103 and the mounting through-hole 104 and extends into the volute 10; the base station also includes a bearing 60 and an oil seal 70. The bearing 60 is provided in the mounting groove 103 and rotatably connects the drive shaft 31 and the volute 10; the oil seal 70 is provided on the side of the bearing 60 close to the wet and dry dual-purpose motor 30 to seal the connection between the bearing 60 and the drive shaft 31.

[0030] The setting of the mounting through hole 104 facilitates the drive shaft 31 to extend into the volute 10 and connect with the first impeller 20; the bearing 60 is provided to facilitate fixing the relative position of the drive shaft 31 with the volute 10 when driving the first impeller 20 to rotate, thereby improving the stability of the drive shaft 31 and facilitating the transmission connection between the drive shaft 31 and the first impeller 20; the setting of the oil seal 70 can improve the stability and sealing of the connection between the bearing 60 and the drive shaft 31. This setting facilitates improving the waterproof effect of the wet and dry dual-purpose motor 30 and improving reliability.

[0031] In some embodiments, the base station also includes a sealing ring 80, which is arranged in the mounting hole 104 to seal the drive shaft 31 and the inner wall of the mounting hole 104. This arrangement facilitates improving the waterproof effect of the wet and dry dual-purpose motor 30 and improving reliability.

[0032] The provision of the sealing ring 80 can further improve the stability of the relative position between the drive shaft 31 and the volute 10 .

[0033] In some embodiments, the first impeller 20 comprises a centrifugal impeller.

[0034] The centrifugal impeller can generate centrifugal force through the rotation of the impeller, thereby changing the flow direction of the airflow or dirt entering from the air inlet of the centrifugal impeller in the volute 10, and can make the airflow or dirt entering the volute 10 be discharged in a direction perpendicular to the air inlet of the centrifugal impeller; wherein, the position of the air inlet of the centrifugal impeller is usually located on the rotation axis a of the centrifugal impeller to reduce the flow deflection of the airflow or dirt. It should be noted that in this embodiment, the air inlet or air outlet of the centrifugal impeller is not limited to the air inlet and outlet. The centrifugal impeller is used here to generate negative pressure and guide the flow of airflow or dirt in the volute 10. The blades of the centrifugal impeller are usually fixed on a circular impeller, and the impeller is installed in a volute-shaped casing (i.e., the volute 10 of the present application). This design makes it easy for the centrifugal impeller to generate higher wind pressure and improve the suction effect on the airflow or dirt.

[0035] In some embodiments, see Figure 2 and Figure 4 The axial directions of the first inlet 101 and the first outlet 102 of the volute 10 are both arranged parallel to the rotation axis a of the first impeller 20 .

[0036] The axial direction of the first inlet 101 of the volute 10 is arranged parallel to the rotation axis a of the first impeller 20, so that the airflow or dirt entering from the first inlet 101 can be consistent with the air inlet direction of the centrifugal impeller, thereby reducing the kinetic energy loss caused by the turning. For example, the axis of the first inlet 101 can be arranged on the same straight line as the rotation axis a of the centrifugal impeller. The axial direction of the first outlet 102 of the volute 10 is arranged parallel to the rotation axis a of the first impeller 20, so that when the first outlet 102 and the first inlet 101 are connected to other pipelines and other components, they can be connected to other pipelines and other components in a direction parallel to the rotation axis a, thereby reducing the size of the base station in a direction perpendicular to the rotation axis a. For example, when the rotation axis a of the first impeller 20 is parallel to the direction of gravity, this arrangement facilitates the first outlet 102 and the first inlet 101 to share the space in the vertical direction when connecting to other pipelines and other components, thereby reducing the space occupied by the base station in the horizontal direction. At this time, the axial direction of the first outlet 102 is parallel to the direction of gravity, so that the effect of gravity is used to increase the sewage discharge speed and improve the user experience.

[0037] In other embodiments, the axial direction of the first inlet of the volute may be arranged parallel to the rotation axis of the first impeller, and the first outlet of the volute may be arranged perpendicular to the rotation axis, wherein the first impeller includes a centrifugal impeller.

[0038] The axial direction of the first inlet 101 of the volute 10 is set to be parallel to the rotation axis a of the first impeller 20, so that the airflow or dirt entering from the first inlet 101 can be consistent with the air inlet direction of the centrifugal impeller, reducing the kinetic energy loss caused by turning. For example, the axis of the first inlet 101 can be set to extend on the same line as the rotation axis a of the centrifugal impeller; further, the first outlet 102 of the volute 10 is set perpendicular to the rotation axis a, so that the airflow or dirt can be consistent with the air outlet direction of the centrifugal impeller when flowing out from the first outlet 102, reducing the kinetic energy loss caused by turning and improving the sewage discharge efficiency. For example, the axis of the first outlet 102 can be set to extend on the same line as the axis of the air outlet of the centrifugal impeller.

[0039] In other embodiments, the axial direction of the first inlet of the volute and the axial direction of the first outlet of the volute may be changed based on the structural requirements of the base station or the space requirements of the external environment, which will not be repeated here.

[0040] In some embodiments, see Figure 2 and Figure 4 The first inlet 101 of the volute 10 has a first projection in a vertical plane of the rotation axis a of the first impeller 20 located within a second projection of the first impeller 20 in the vertical plane, and the third projection of the first outlet 102 of the volute 10 in the vertical plane is located outside the second projection; wherein the first impeller 20 includes a centrifugal impeller.

[0041] Among them, the vertical plane of the rotation axis a of the first impeller 20 refers to a plane perpendicular to the rotation axis a, the projection of the first inlet 101 of the volute 10 in the plane is the first projection, the projection of the first impeller 20 in the plane is the second projection, and the projection of the first outlet 102 of the volute 10 in the plane is the third projection; the third projection is located outside the second projection, which means that the third projection does not overlap with the second projection, for example, they can be arranged at intervals or in contact on the plane.

[0042] The first projection is arranged to be located within the second projection, so as to facilitate setting the airflow or dirt to enter the first inlet 101 along the air inlet direction of the centrifugal impeller. For example, the first projection can be arranged to be located at the center of the second projection, so as to facilitate setting the rotation axis a of the centrifugal impeller to pass through the first inlet 101, so as to facilitate setting the axis of the air inlet of the centrifugal impeller and the axis of the first inlet 101 to be on the same straight line, thereby reducing the kinetic energy loss of the airflow or dirt caused by turning during the flow process, and improving the sewage discharge efficiency; the third projection is arranged to be located outside the second projection, so as to facilitate setting the centrifugal impeller to guide the airflow or dirt to the first outlet 102 along the air outlet direction of the centrifugal impeller. For example, the third projection can be arranged to be located in the peripheral area of ​​the second projection, so as to facilitate setting the position of the first outlet 102 closer to the air outlet position of the centrifugal impeller, thereby reducing the turning of the airflow or dirt when flowing out of the volute 10, reducing the kinetic energy loss, and improving the sewage discharge efficiency.

[0043] For example, in one application scenario, it is not limited whether the axial direction of the first inlet 101 and the axial direction of the first outlet 102 are parallel or perpendicular to the rotation axis a of the first impeller 20. The third projection is located outside the second projection, which is convenient for setting the first outlet 102 on the outer peripheral side of the centrifugal impeller, so as to facilitate the diversion of airflow or dirt directly out of the volute 10.

[0044] In other embodiments, the positional relationship among the first projection, the third projection, and the second projection may be changed based on the structural requirements of the base station or the spatial requirements of the external environment.

[0045] In some embodiments, the first outlet 102 and the first inlet 101 of the volute 10 are located on one side of the first impeller 20 , and the wet / dry dual-purpose motor 30 is located on the other side of the first impeller 20 .

[0046] The above arrangement makes the first outlet 102 and the first inlet 101 of the volute 10 located on the same side of the first impeller 20, which is convenient for saving layout space; the drive shaft 31 of the wet and dry dual-purpose motor 30 is connected to the first impeller 20, so as to drive the first impeller 20 to rotate; the first outlet 102 and the first inlet 101 of the volute 10 are located on one side of the first impeller 20, and the wet and dry dual-purpose motor 30 is located on the other side of the first impeller 20, so as to reduce the interference of the position of the wet and dry dual-purpose motor 30 on the position of the first inlet 101, and to facilitate setting the axial direction of the first inlet 101 to extend along the rotation axis a of the first impeller 20, so as to reduce the flow diversion of airflow or dirt; the first outlet 102 and the first inlet 101 of the volute 10 are located on one side of the first impeller 20, and the wet and dry dual-purpose motor 30 is located on the other side of the first impeller 20, so as to reduce the interference of dirt discharged from the first outlet 102 on the reliability of the wet and dry dual-purpose motor 30, so this arrangement can improve the reliability and safety of use of the wet and dry dual-purpose motor 30.

[0047] In some embodiments, the drive shaft 31 of the wet / dry dual-purpose motor 30 , the first inlet 101 of the volute 10 , and the rotation axis a of the first impeller 20 are coaxially arranged.

[0048] The above arrangement facilitates the wet / dry dual-purpose motor 30 to drive the first impeller 20 to rotate, and facilitates the axis of the first inlet 101 to be in the same straight line with the air inlet direction of the first impeller 20, thereby facilitating the use of the negative pressure effect to guide the airflow or waste into the volute 10.

[0049] In some embodiments, the base station also includes a second impeller 40, and the two ends of the drive shaft 31 of the wet and dry dual-purpose motor 30 are respectively connected to the first impeller 20 and the second impeller 40 to drive the first impeller 20 and the second impeller 40 to rotate synchronously; the second impeller 40 is arranged on the side of the wet and dry dual-purpose motor 30 away from the first impeller 20.

[0050] The setting of the second impeller 40 facilitates the heat dissipation of the wet and dry dual-purpose motor 30, and can improve the reliability and safety of the use of the wet and dry dual-purpose motor 30; the second impeller 40 is arranged on the side of the wet and dry dual-purpose motor 30 away from the first impeller 20, so that the second impeller 40 and the first impeller 20 share the drive shaft 31 of the wet and dry dual-purpose motor 30, which is convenient for simplifying the structure and facilitating the wet and dry dual-purpose motor 30 to drive the first impeller 20 and the second impeller 40 to rotate simultaneously.

[0051] It should be noted that the drive shaft 31 can be the output shaft of the wet and dry dual-purpose motor 30. In other embodiments, the wet and dry dual-purpose motor can also be connected to the first impeller and the second impeller through a rotating component. The rotating component includes a rotating shaft, etc., which will not be repeated here; in other embodiments, the position of the second impeller can also be adjusted according to layout requirements, which will not be repeated here.

[0052] In some embodiments, the base station further comprises a filter 50 , wherein a second inlet of the filter 50 is connected to the input waste, and a second outlet of the filter 50 is connected to the first inlet 101 of the volute 10 .

[0053] In one application scenario, the filter 50 is used to filter the dirt flowing out from the sewage outlet of the main unit. The dirt enters the second inlet of the filter 50 from the sewage outlet of the main unit, and after flowing into the filter 50, flows out from the second outlet of the filter 50 to the first inlet 101 of the volute 10, and then enters the volute 10.

[0054] In some embodiments, the filter 50 also includes a first opening, which is arranged at the top of the filter 50, and a second inlet is arranged on the side wall of the filter 50, so as to facilitate taking out the filter 50 after the filtration is completed. The filter cavity inside the filter 50 can be cleaned through the first opening. In some application scenarios, the second outlet can also be used as a filter hole of the filter 50.

[0055] In some embodiments, the second outlet of the filter 50 is disposed opposite to the first opening of the filter 50 , and the second outlet of the filter 50 is disposed on the bottom wall of the filter 50 , so as to utilize gravity to increase the filtering speed.

[0056] In some embodiments (not shown), the filter further comprises a cover body, which covers the first opening. The filter further comprises a filter housing and a filter element. The filter housing defines a first opening, a second inlet, a second outlet, and a filter cavity, which communicates with the first opening, the second inlet, and the second outlet. The filter element is detachably mounted on the cover body and extends into the filter cavity. This arrangement facilitates cleaning of the filter element.

[0057] In one application scenario, dirt enters the filter chamber through the second inlet, is filtered once after passing through the filter element, and the filtered liquid or solid-liquid mixture flows out of the filter through the second outlet.

[0058] In some embodiments, the filter element includes a filter grid disposed adjacent to the second inlet and between the second inlet and the second outlet.

[0059] Specifically, after the dirt enters the filter chamber through the second inlet, it is filtered once at the filter grating. The large particles filtered out are retained in the area between the second inlet and the filter grating. The filtered solid-liquid mixture or liquid continues to flow in the filter chamber after passing through the filter grating until it flows to the second outlet and is discharged from the filter chamber.

[0060] In one application scenario, the second outlet can also be set to multiple filter holes to achieve secondary filtration of dirt.

[0061] In some embodiments, the base station also includes a first shell 500 and a second shell 300. The first shell 500 forms a first accommodating chamber and a third inlet 501 and a third outlet connected to the first accommodating chamber. The filter 50 is arranged in the first accommodating chamber. The third inlet 501 is used to input dirt and is connected to the second inlet. The third outlet is used to connect the second outlet and the first inlet 101; the second shell 300 forms a second accommodating chamber for accommodating a wet and dry dual-purpose motor 30; wherein the first shell 500 and the second shell 300 are detachably connected, and the volute 10 and the second shell 300 are detachably connected; the volute 10 and the second shell 300 are arranged along the rotation axis a of the first impeller 20, and the first shell 500 and the second shell 300 are arranged in a direction perpendicular to the rotation axis a.

[0062] Specifically, dirt reaches the second inlet of the filter 50 through the third inlet 501 and then flows into the filter cavity. Dirt that flows out of the filter cavity through the second outlet can flow through the third outlet to the first inlet 101 of the volute 10. For example, in one application scenario, the second outlet is provided at the bottom of the filter 50, and the third outlet is provided at the bottom of the first housing 500. The bottom of the filter 50 is spaced apart from the bottom of the first housing 500. Dirt that flows out of the filter cavity through the second outlet enters the first accommodating cavity, then flows to the third outlet, and then flows to the first inlet 101 connected to the third outlet.

[0068] This application further proposes a cleaning system, such as Figures 1 to 6 The cleaning system includes the above-mentioned base station.

[0069] The specific implementation and working principle of the base station can be found in the above embodiments and will not be described again here.

[0070] In some embodiments, the cleaning system includes a host and a base station, and the first inlet 101 of the volute 10 is used to communicate with the sewage outlet of the host.

[0071] Among them, the cleaning system includes sweepers, scrubbers, integrated washing and drying machines, integrated sweepers and mops, etc., without specific limitations. Among them, the host includes cleaning equipment for cleaning the surface or object to be cleaned, such as a scrubber host, a sweeper host, etc. The dirt in the host can be liquids such as sewage, solids such as dust or debris, or a solid-liquid mixture formed by a mixture of particulate matter and sewage, etc., without specific limitations; in some application scenarios, the base station can charge the host or clean or dry at least some components of the host, such as a scrubber base station, a sweeper base station, etc., which can charge cleaning equipment such as a scrubber host and a sweeper host. For example, the scrubber base station can clean and dry the cleaning cloth on the scrubber host, etc., without specific limitations.

[0072] In one application scenario, the host is physically docked with the base station, and the sewage outlet of the host and the first inlet 101 of the volute 10 can be in corresponding positions. When the wet and dry dual-purpose motor 30 drives the first impeller 20 to work, negative pressure is generated in the volute 10. Under the action of the negative pressure, the sewage outlet and the first inlet 101 of the host are connected. The dirt in the host enters the volute 10 through the first inlet 101 under the action of the negative pressure. The dirt in the volute 10 is sucked into the first impeller 20 and stirred by the first impeller 20 to the sewage outlet (i.e., the first outlet 102) of the base station for discharge.

[0073] Different from the prior art, the first impeller of the present application is arranged in the volute, and negative pressure can be generated in the volute during operation, so that the dirt enters the volute serving as a sewage collecting chamber through the first inlet under the action of negative pressure. The dirt in the volute is sucked into the first impeller and stirred by the first impeller to be discharged to the sewage outlet of the base station. Therefore, there is no need to set up a special sewage collecting chamber, which can simplify the sewage discharge structure of the base station, facilitate the miniaturization of the base station, and improve the user experience; further, the setting of the wet and dry dual-purpose motor facilitates automatic sewage discharge, and the wet and dry dual-purpose motor can work stably in dry and wet environments, which can improve the multi-scenario practicality of the base station and improve the user's convenience; the drive shaft is sealed and connected to the volute and can be rotatably arranged, which can improve the position stability of the wet and dry dual-purpose motor during operation and improve reliability.
