Without more limitations, the element defined by the statement "including a" does not exclude the presence of additional identical elements in the process, method, article or apparatus including the element. "Multiple" means greater than or equal to two.

[0037] Please refer to Figures 1 to 4 The embodiment of the present application provides a cleaning base station, which comprises a main body 10 and a cleaning assembly 20.

[0038] The main body 10 has a containing cavity 11 for parking the cleaning device. That is, the containing cavity 11 of the main body 10 is used for parking the cleaning device.

[0039] In some embodiments, the functions of the cleaning base station include but are not limited to charging, dust removal, drying, disinfection, cleaning, etc. of the cleaning device.

[0040] It should be noted that the cleaning device is used to walk on the ground to clean the ground by suction and / or mopping, and the cleaning device is used to clean the ground by sucking the garbage on the ground into the dust collecting cavity in the cleaning device and using the cleaning part on the cleaning device to scrub the ground, for example, the cleaning device can be a sweeper, a mop, etc.

[0041] The cleaning assembly 20 is arranged at the bottom of the accommodating cavity 11, facilitating the cleaning equipment to drive above the cleaning assembly 20, so that the cleaning assembly 20 can clean the cleaning part of the cleaning equipment. The cleaning part can be a cloth, a roller or the like.

[0042] Please refer to Figure 2 、 Figure 3 and Figure 4 , the cleaning assembly 20 includes a cleaning disc 21 and a filter assembly 22. The cleaning disc 21 includes a sewage collection groove 211 for collecting liquid and a drainage passage for draining the liquid in the sewage collection groove 211. The filter assembly 22 is detachably arranged in the sewage collection groove 211 as a whole. That is, the liquid discharged into the sewage collection groove 211 needs to pass through the filtering effect of the filter assembly 22 first, so as to reduce the garbage in the liquid entering the sewage collection groove 211, thereby reducing the possibility of the drainage passage being blocked and improving the sewage drainage effect in the sewage collection groove 211. Moreover, the filter assembly 22 is detachably arranged in the sewage collection groove 211 as a whole, facilitating the filter assembly 22 to be detached to clean the filter screen 221 alone, which helps to ensure the filtering effect of the filter screen 221.

[0043] Please refer to Figure 3 and Figure 4 , the filter assembly 22 includes a filter screen 221 arranged on the top side of the groove bottom wall 2111 of the sewage collection groove 211. The filter screen 221 allows the garbage in the sewage to be intercepted on the upper surface of the filter screen 221.

[0044] It should be noted that the interval between the filter screen 221 and the groove bottom wall 2111 in the height direction is relatively small, the liquid in the sewage collection groove 211 has interfacial tension, and the filter screen 221 is easy to adhere to the groove bottom wall 2111 under the action of the interfacial tension of the liquid, thereby reducing the filtering effect of the filter screen 221, and even possibly causing the liquid in the sewage collection groove 211 to be difficult to drain in time. Therefore, in some embodiments of the present application, the cleaning assembly 20 includes a spacing structure 30 arranged between the filter screen 221 and the groove bottom wall 2111. The spacing structure 30 has a stop effect on the filter screen 221, preventing the filter screen 221 from contacting the groove bottom wall 2111, thereby facilitating the improvement of the sewage drainage effect and the guarantee of the filtering effect of the filter screen 221.

[0045] It should be noted that the height direction is the direction from the top to the bottom in Figure 1 , that is, it includes the direction from the top to the bottom, and also includes the direction from the bottom to the top.

[0046] In some embodiments, the main body 10 comprises a negative pressure source, which is in communication with the drainage channel, and is configured to form a negative pressure in the drainage channel to suck the liquid in the sewage collection tank 211. The negative pressure formed in the drainage channel has a suction effect on the liquid in the sewage collection tank 211, which helps to improve the drainage efficiency. The negative pressure source can be a water pump, for example.

[0047] As shown in Figs. 1 and 2, the cleaning assembly 20 comprises a pipe 23, the inlet end of which extends into the sewage collection tank 211 from top to bottom, and the space in the pipe 23 constitutes at least part of the drainage channel. Figure 3 Figure 4 As shown in Figs. 1 and 2, the cleaning assembly 20 comprises a pipe 23, the inlet end of which extends into the sewage collection tank 211 from top to bottom, and the space in the pipe 23 constitutes at least part of the drainage channel.

[0048] In some embodiments, the main body 10 comprises a sewage tank, which is provided with a sewage interface 111 in communication with the pipe 23, and is configured to drain the liquid in the pipe 23 to the sewage tank.

[0049] It can be understood that in other embodiments, the liquid in the sewage collection tank 211 can also flow out of the sewage collection tank 211 under the action of gravity, in which case, a drainage hole can be formed at the junction of the tank bottom wall 2111 and the tank side wall 2112, or at the end of the tank side wall 2112 close to the tank bottom wall 2111.

[0050] It can be understood that in this embodiment, since the liquid in the sewage collection tank 211 can flow out of the sewage collection tank 211 under the action of gravity, a negative pressure source does not need to be provided, thereby reducing the manufacturing cost.

[0051] In some embodiments, the spacing structure 30 is fixed to the tank bottom wall 2111. Since the filter screen 221 needs to be disassembled, fixing the spacing structure 30 to the tank bottom wall 2111 helps to maintain the stability of the spacing structure 30.

[0052] Of course, in other embodiments, the spacing structure 30 can also be fixed to the bottom side of the filter screen 221; or the position of the spacing structure 30 is not fixed, i.e. the spacing structure 30 is neither connected to the cleaning disc 21 nor connected to the filtering assembly 22, and the spacing structure 30 is placed as an independent component between the filter screen 221 and the tank bottom wall 2111, and the position of the spacing structure 30 can be moved after the filtering assembly 22 is removed. ​

[0053] In some embodiments, the spacing structure 30 is integrated with the bottom wall 2111 of the sump. In this way, the stability of the spacing structure 30 is further improved, and the assembly of the spacing structure 30 is avoided, which facilitates the fixation of the spacing structure 30 to the bottom wall 2111 of the sump.

[0054] In some embodiments, as shown in Figure 3 and Figure 4 , a portion of the bottom wall 2111 of the sump is concave downward to form a notch 24, and the inlet of the drainage channel is communicated with the notch 24. The notch 24 has a collection effect on the liquid, which helps to improve the drainage effect of the drainage channel.

[0055] In the embodiments in which the cleaning assembly 20 includes the pipe 23, the inlet end of the pipe 23 is inserted into the notch 24, and the collection effect of the notch 24 on the liquid helps to improve the suction efficiency of the pipe 23.

[0056] The specific shape of the spacing structure 30 is not limited, as long as it can stop the filter screen 221 in the height direction to prevent the filter screen 221 from contacting the bottom wall 2111 of the sump.

[0057] For example, in some embodiments, the spacing structure 30 can include a protrusion, which can include at least one of a ball structure, a cylinder extending in the height direction, a circular truncated cone, and a conical structure.

[0058] In some embodiments, as shown in Figure 3 and Figure 4 , the spacing structure 30 includes a rib, one end of the rib extending to the edge of the notch 24. The rib can guide the liquid in the sump 211 to the notch 24, which helps to improve the drainage effect, and the guiding effect of the rib helps to improve the distribution of the liquid in the sump 211, such as reducing the local concentration of the liquid in the sump 211, which helps to alleviate the adsorption of the liquid in the sump 211 due to interfacial tension, so as to make the liquid as much as possible to be guided to the notch 24 by the rib, thereby reducing the residue of the liquid in the sump 211 to improve the drainage effect.

[0059] The rib can extend in a straight line, or in a curved line, or in a broken line, etc., which is not limited here.

[0060] Please refer to Figure 3 and Figure 4 , the cleaning disc 21 has a cleaning area 212, and the cleaning assembly 20 includes a cleaning mechanism 25 arranged in the cleaning area 212. The cleaning mechanism 25 is used for scraping and / or extruding the cleaning part of the cleaning device, so as to clean the garbage and stains attached to the cleaning part.

[0061] In some embodiments, the cleaning mechanism 25 can include one or more cleaning brushes 251. The cleaning brushes 251 are movable relative to the cleaning tray 21, for example, rotatable, or linearly movable, etc., and are used to clean the cleaning elements during movement.

[0062] The cleaning area 212 has a communication port 2121 through which liquid in the cleaning area 212 is drained to the filter screen 221. The communication port 2121 and the drainage channel are located on opposite sides of the sewage collection tank 211 in the first direction. That is, the drainage channel is arranged away from the cleaning area 212 in the first direction, which helps to reduce the influence of the sewage in the drainage channel on the cleaning area 212.

[0063] Exemplarily, the first direction is the direction shown in Figure 3 and Figure 4 . It can be understood that the first direction can also be understood as the direction in which the cleaning device enters or exits the containing cavity 11.

[0064] In some embodiments, the spacing structure 30 includes one or more ribs, and at least one rib extends in the first direction. That is, the ribs guide the liquid to the drainage channel in the first direction, which can make the liquid flow to the drainage channel faster, thereby helping to improve the drainage efficiency.

[0065] In some embodiments, in the embodiment in which the spacing structure 30 includes a plurality of ribs, the plurality of ribs are arranged at intervals in a second direction, wherein the second direction is perpendicular to the first direction. The interval formed by the adjacent two ribs can better guide the liquid, thereby helping to improve the drainage effect.

[0066] Exemplarily, the second direction is the direction shown in Figure 3 and Figure 4 . It should be noted that the second direction is perpendicular to the first direction, which means that the second direction is approximately perpendicular to the first direction, that is, there is a certain installation error.

[0067] It can be understood that in other embodiments, the number of ribs can also be one, three, four, five, etc., which can be set according to the volume of the sewage collection tank 211 or the area of the tank bottom wall 2111.

[0068] In some embodiments, referring to Figure 2 , Figure 3 and Figure 4 , the filter assembly 22 includes a first connecting structure 222 arranged at a first end 2211 of the filter screen 221 in the first direction, and the first connecting structure 222 is detachably connected with the cleaning tray 21. In this way, the entire filter assembly 22 is detachably arranged in the sewage collection tank 211.

[0069] In some embodiments, the first connecting structure 222 further has a force applying part 2221, which is located outside the sewage collecting tank 211. By applying force to the force applying part 2221, the first connecting structure 222 can be disassembled, and the force applying part 2221 is located outside the sewage collecting tank 211, so that the operator can avoid contacting the sewage in the sewage collecting tank 211 or the garbage on the filter screen 221 as much as possible when installing or disassembling the filter assembly 22, thereby facilitating the operator to disassemble or assemble the filter assembly 22.

[0070] For example, referring to Figure 3 and Figure 4 , the sewage collecting tank 211 has a tank side wall 2112, the first connecting structure 222 includes an elastic hook 2222, the elastic hook 2222 can be elastically deformed in the first direction and abut against the inner surface of the tank side wall 2112 under the action of its own elastic force, and the force applying part 2221 is connected to the free end of the elastic hook 2222 and extends out of the sewage collecting tank 211 from the top edge of the tank side wall 2112 in the first direction. In this way, when the filter assembly 22 needs to be disassembled, force is applied to the force applying part 2221 in the first direction, so that the elastic hook 2222 is compressed and moves away from the inner surface of the tank side wall 2112, and the filter assembly 22 can be removed; when the filter assembly 22 needs to be assembled, the elastic hook 2222 is also compressed, and the filter assembly 22 is placed in the sewage collecting tank 211 as a whole, so that the elastic hook 2222 abuts against the inner surface of the tank side wall 2112 under the action of its own elastic force, and the filter assembly 22 can be assembled. The disassembly and assembly processes are convenient and fast.

[0071] In this embodiment, as shown in Figure 2 , the force applying part 2221 extends out of the sewage collecting tank 211 from the top edge of the tank side wall 2112 in the first direction, which can avoid the force applying part 2221 contacting the sewage in the sewage collecting tank 211 or the garbage on the filter screen 221 as much as possible, and on the other hand, the top edge of the tank side wall 2112 can provide support to the force applying part 2221, which helps to enhance the stability of the installation of the filter screen 221 assembly.

[0072] In some embodiments, referring to Figure 3 and Figure 4 , the filter screen 221 has a second end 2212, which is oppositely arranged to the first end 2211 in the first direction, and the position of the first end 2211 is higher than that of the second end 2212. In this way, the position of the force applying part 2221 can be higher, so as to further avoid the force applying part 2221 contacting the sewage in the sewage collecting tank 211 or the garbage on the filter screen 221 as much as possible.

[0073] In some embodiments, the filter assembly 22 comprises a clamping portion 223 arranged at the second end 2212, and the cleaning area 212 is provided with a clamping hole (not shown in the figure) for the clamping portion 223 to be inserted into the side wall of the sewage collection tank 211. In this way, when the filter assembly 22 is installed, the clamping portion 223 can play a role of pre-positioning, and after the assembly is completed, the clamping portion 223 inserted into the clamping hole also helps to make the structure of the filter assembly 22 stable, so as to improve the use stability of the cleaning assembly 20.

[0074] In some embodiments, as shown in Figure 1 , the main body 10 comprises a detection element 112. As shown in Figure 3 and Figure 4 , the cleaning assembly 20 comprises a magnetic element 27. The detection element 112 is used to detect the magnetic field signal of the magnetic element 27. The detection element 112 judges whether the cleaning assembly 20 is assembled in place through the detected magnetic field signal.

[0075] It can be understood that the detection element 112 can be at least one of a Hall sensor, a magnetoresistance sensor or a fluxgate sensor.

[0076] In some embodiments, the magnetic element 27 is arranged at the filter assembly 22. In this way, not only can it be detected whether the cleaning assembly 20 is installed in place, but also whether the filter assembly 22 is missing.

[0077] In this embodiment, as shown in Figure 3 , the magnetic element 27 can be arranged at the first end 2211 of the filter screen 221, which helps to ensure that the magnetic element 27 is within the detection range of the detection element 112, thereby improving the detection accuracy.

[0078] In some embodiments, the cleaning assembly 20 comprises a first pole piece 261 and a second pole piece 262 (see Figure 3 ), which are used to contact the liquid in the sewage collection tank, and the main body 10 comprises a detection circuit, a first spring sheet 113 and a second spring sheet (not shown in the figure) electrically connected to the detection circuit, the first pole piece 261 is electrically connected to the first spring sheet 113, and the second pole piece 262 is electrically connected to the second spring sheet. The first pole piece 261 and the second pole piece 262 are used to establish a conductive path through the liquid in the sewage collection tank 211 under the condition that the liquid level in the sewage collection tank 211 reaches a set threshold, so as to make the detection circuit generate a water full detection signal. In this way, it helps to avoid that the liquid in the sewage collection tank 211 exceeds the set threshold or even overflows to the outside of the sewage collection tank 211.

[0079] It can be understood that the set threshold of the liquid level in the sewage collection tank 211 can be set according to actual conditions, and the embodiments of the present application are not limited.

[0080] In some embodiments, referring to Figure 3 The first and second polar plates 261 and 262 are arranged on opposite sides of the groove side wall 2112 of the sewage collecting groove 211 in the second direction. The first and second elastic plates 113 and 114 are arranged on opposite sides of the side wall of the accommodating cavity 11 of the main body 10, so that the first polar plate 261 and the first elastic plate 113 are electrically connected, and the second polar plate 262 and the second elastic plate 114 are electrically connected.
