It will be appreciated that in some embodiments, the number of the fool-proof positioning members may be one, that is, the indicator 421 indicates that the filtering device 40 is installed in place when the fool-proof positioning members are matched with the fool-proof limiting members 46, otherwise, the indicator 421 indicates that the filtering device 40 is not installed in place, which is advantageous for further simplifying the structure.

In the above embodiment, the filtering device 40 is detachably disposed in the cleaning tank 22, and the filtering device 40 can be detached from the cleaning tank 22 for cleaning, maintenance or replacement, so that the operation is simple and convenient.

Further, as shown in fig. 12, the filtering device 40 may be disposed at the bottom of the cleaning tank 22, which is advantageous for improving the thoroughness of the filtering device 40 for filtering the liquid in the cleaning tank 22.

Wherein, the filter device 40 can be located at least one side of the cleaning tank 22, i.e. the filter device 40 can be only arranged at the bottom of one side of the cleaning tank 22, or the filter devices 40 are arranged at the bottoms of two sides of the cleaning tank 22, and the different setting positions of the filter device 40 can meet the requirements of different structures of the filter device 40 and different filtering efficiencies of the cleaning tank 22, so that the application range of the product is enlarged.

In some possible embodiments provided by the present invention, as shown in fig. 13, the bottom of the cleaning tank 22 is provided with a mounting groove, and a part of the filtering device 40 is adapted to be located inside the mounting groove, and the first fool-proof locating member 241 and the second fool-proof locating member 242 are disposed above the mounting groove, for example, the first fool-proof locating member 241 and the second fool-proof locating member 242 are disposed on the inner side wall of the cleaning tank 22, and the first fool-proof locating member 241 is located above the second fool-proof locating member 242. The indicator 421 may comprise a planar structure located above the fool-proof limiter 46, e.g. the indicator 421 is the top surface of the filter device 40. When the user is installing the filter device 40, for example, simply placing the filter device 40 in the installation groove without applying a downward pressure to the filter device 40, the fool-proof stopper 46 is abutted by the first fool-proof positioning member 241. At this time, the indication member 421, i.e. the planar structure above the fool-proof limiting member 46 is higher than the top 221 of the cleaning tank 22, indicates that the filtering device 40 is not installed in place, i.e. the sidewall of the filtering device 40 near the inside of the cleaning tank 22 protrudes from the bottom of the cleaning tank 22, and at this time, the liquid at the bottom of the cleaning tank 22 outside the installation tank may not smoothly flow through the filtering device 40 under the shielding of the sidewall, and the filtering device 40 needs to be reinstalled. Since the indicator 421 protrudes significantly from the cleaning tank 22, the user can be alerted that the filter device 40 is not in place. Upon indication by the user, downward pressure may be applied to the filter apparatus 40 to urge the fool-proof limiter 46 downwardly and into engagement with the second fool-proof retainer 242, i.e., the fool-proof limiter 46 is located on the lower surface of the second fool-proof retainer 242. At this time, the indication member 421, i.e. the plane structure of the fool-proof limiting member 46, is located in the cleaning tank 22, i.e. the plane structure is located below the tank top 221 of the cleaning tank 22 or is flush with the tank top 221, to indicate that the filtering device 40 is installed in place, and at this time, the liquid at the tank bottom of the cleaning tank 22 located outside the installation tank can smoothly flow through the filtering device 40 to realize filtering.

Wherein, the indicator 421 is a planar structure above the fool-proof limiting member 46, and the planar structure is convenient for comparing with the flatness of other components, so that a user can confirm whether the filtering device 40 is installed in place or not through the planar structure, and the planar structure is convenient to process, easy to realize and suitable for popularization and application. Further, the planar structure may be colored or provided with an indicator light or the like to further play a role of reminding and facilitating recognition, such as coloring the planar structure with yellow, red or other relatively bright color, so that the user can quickly and accurately find the position of the planar structure and determine whether the planar structure protrudes from the groove top 221 of the cleaning groove 22 to determine whether the filtering device 40 is in place.

That is, in the base station 20 provided by the embodiment of the invention, by arranging the installation groove at the groove bottom of the cleaning groove 22, whether the filtering device 40 is accurately installed in place relative to the cleaning groove 22 can be determined by utilizing the relative position relationship between the top surface of the filtering device 40 and the groove top 221 of the cleaning groove 22, such as whether the top surface of the filtering device 40 protrudes out of the cleaning groove 22, so that the base station has a simple structure, good prompting function and accurate prompting result, and is convenient for a user to confirm whether the filtering device 40 is installed in place.

The first foolproof locating piece 241, the second foolproof locating piece 242 and the foolproof locating piece 46 can limit the movement of the filtering device 40 relative to the cleaning groove 22, for example, limit the movement of the filtering device 40 relative to the cleaning groove 22 along the vertical upward direction, thereby being beneficial to realizing the pre-locating of the installation process of the filtering device 40, and the reliable connection of the filtering device 40 and the base station body 21, and has simple structure and easy realization.

In the embodiment of the present invention, the second fool-proof positioning member 242 may also function to fix the filter device 40 when the filter device 40 is properly mounted to the mounting groove. In addition, the first fool-proof locating piece 241 is located above the second fool-proof locating piece 242, so that when the fool-proof limiting piece 46 is jacked up by the first fool-proof locating piece 241, a user can be more obviously prompted that the user filtering device 40 is not correctly installed to the cleaning slot 22, which is beneficial to improving the reliability of the operation of the base station 20.

In the above embodiment, as shown in fig. 8 and 10, the filtering device 40 includes the connecting portion 47 extending to the upper portion of the installation groove, and the fool-proof limiting member 46 is disposed on the connecting portion 47, so that the problem that the filtering effect is affected because part of the liquid cannot flow through the filtering device 40 due to the fact that the fool-proof limiting member 46 is located in the installation groove and the gap between the filtering device 40 and the installation groove is large is avoided, that is, the limiting member 46 located above the installation groove is matched with the second fool-proof positioning member 242, connection tightness between the filtering device 40 and the installation groove is improved, and good filtering effect is ensured.

In the above embodiment, the fool-proof limiting member 46 includes a buckle structure, the first fool-proof positioning member 241 and the second fool-proof positioning member 242 are both elastic members, where the first fool-proof positioning member 241 includes a first abutting portion 243 adapted to abut against the fool-proof limiting member 46, the second fool-proof positioning member 242 includes a second abutting portion 245 adapted to abut against the fool-proof limiting member 46, and the first abutting portion 243 is located above the second abutting portion 245, so that the movement of the filtering device 40 relative to the base station body 21 can be limited by abutting the fool-proof limiting member 46 with the first abutting portion 243 and the second abutting portion 245, and the pre-positioning and detachable connection between the filtering device 40 and the base station body 21 can be achieved by using the elasticity of the first fool-proof positioning member 241 and the second fool-proof positioning member 242.

For example, in the assembly process of the filter device 40, when the fastening structure of the fool-proof limiting member 46 abuts against the first abutting portion 243 of the first fool-proof positioning member 241, the planar structure of the connecting portion 47 of the filter device 40 above is higher than the top 221 of the cleaning slot 22, which indicates that the filter device 40 is not installed in place. Because the first fool-proof positioning member 241 is an elastic member, the elastic force of the first fool-proof positioning member 241 acting on the fool-proof limiting member 46 is overcome, and the filtering device 40 is continuously pressed downwards, so that the fastening structure of the fool-proof limiting member 46 is abutted with the second abutting portion 245 of the second fool-proof positioning member 242, the planar structure of the connecting portion 47 of the filtering device 40 above will be located in the cleaning groove 22, for example, the planar structure is flush with the groove top 221 of the cleaning groove 22, or the planar structure is lower than the groove top 221 of the cleaning groove 22, which indicates that the filtering device 40 is installed in place. The filtering device 40 can be reliably and stably limited in the mounting groove by utilizing the elastic force of the second fool-proof locating piece 242 acting on the fool-proof limiting piece 46, so that the reliable connection between the filtering rotating shaft and the base station body 21 is realized.

Further, as shown in fig. 8 and 9, the inner side wall of the installation groove is provided with a groove structure, the outer wall of the filtering device 40 is provided with a protrusion structure 422 which is matched with the groove structure, and the assembly of the filtering device 40 and the installation groove can be pre-positioned through the matching of the groove structure and the protrusion structure 422, so that the assembly efficiency of the filtering device 40 and the installation groove can be improved.

In the above embodiment, as shown in fig. 13, the first fool-proof positioning member 241 further includes the first supporting portion 244 connecting the first abutting portion 243 and the base station body 21, which is beneficial to improving the reliability of the connection of the first abutting portion 243 and the base station body 21. The second fool-proof positioning member 242 further includes a second supporting portion 246 connecting the second abutting portion 245 and the base station body 21, which is beneficial to improving the reliability of the connection between the second abutting portion 245 and the base station body 21. It can be appreciated that the first supporting portion 244 and the first abutting portion 243 may be in an integral structure or a split structure, the second supporting portion 246 and the second abutting portion 245 may be in an integral structure or a split structure, that is, the first fool-proof positioning member 241 may be in an integral structure or a split structure, and the second fool-proof positioning member 242 may be in an integral structure or a split structure, wherein the integral structure is convenient for production, simplifies the assembly process, and is beneficial to reducing the manufacturing cost; the split structure is beneficial to reducing maintenance and replacement cost. Further, the first fool-proof positioning piece 241 and the second fool-proof positioning piece 242 can be integrated with the base station body 21, so that the processing is convenient, the assembling process is simplified, and the manufacturing cost is reduced.

The first supporting portion 244 and/or the second supporting portion 246 may be elastic bending structures, that is, by utilizing elastic deformation of the bending structures, the first abutting portion 243 and/or the second abutting portion 245 can move relative to the base station body 21, so that the first abutting portion 243 and/or the second abutting portion 245 can reliably and tightly abut against the fastening structure of the foolproof limiting member 46, or the fastening structure can be smoothly separated from the first abutting portion 243 and/or the second abutting portion 245, and the structure is simple, easy to implement and low in cost.

Specifically, the bending structure is at least one of L-type, Z-type, V-type, N-type, and M-type, and different shapes of the bending structure can meet the requirements of different positions and different structures of the first abutting portion 243 and/or the second abutting portion 245. The first abutting portion 243 and/or the second abutting portion 245 may be protrusions, clamping grooves, or other structures meeting the requirements, and embodiments of the present invention are not limited in particular.

Specifically, as shown in fig. 13, the side wall of the installation groove is provided with a track groove 23 for the cleaning assembly 30 to pass through, and the first fool-proof positioning piece 241 and the second fool-proof positioning piece 242 are arranged near one end of the track groove 23, so that the influence of the first fool-proof positioning piece 241 and the second fool-proof positioning piece 242 on the movement range of the cleaning assembly 30 can be reduced, the movement range of the cleaning assembly 30 can be increased to a greater extent, and the cleaning effect can be improved.

On the other hand, the filter screen 42 and the shell 43 are of an integrated structure, so that the production is convenient, the assembly operation is simplified, and the production efficiency is improved. It will be appreciated that in the case of a unitary construction of the filter screen 42 and the housing 43, the impact force of the liquid may be used to clean the sediment deposited in the receiving chamber. And for larger particulate solid impurities remaining on the filter screen 42, the cleaning can be directly performed due to the outside of the accommodating cavity.

Alternatively, the float assembly 41 may also be in communication with the receiving chamber.

Further, when the filtering device 40 is disposed in the cleaning tank 22 and the liquid surface in the cleaning tank 22 is within a specific range, the non-contact sensing element can sense the non-contact sensed element, which indicates that the filtering device 40 is accurately mounted on the base station body 21, and the water level in the cleaning tank 22 is within a specific range, for example, the water level in the cleaning tank 22 is at a safe position and does not affect the normal operation of the base station. Namely, the detection device composed of the float assembly 41, the non-contact type sensing element and the non-contact type sensed element can detect the liquid level in the cleaning tank 22 and the current position of the filtering device 40 at the same time, so that the functions of the float assembly 41 are enlarged, the setting of the detection device is simplified, namely, the structure of a product is simplified, the system software program and algorithm are simplified, the cost can be effectively saved, and the detection device is suitable for popularization and application.

That is, in the base station 20 provided by the embodiment of the present invention, the float assembly 41 is disposed on the filtering device 40 and is matched with the non-contact sensing element and the non-contact sensed element, so that the base station 20 can detect whether the filtering device 40 is installed in the cleaning tank 22 and whether the water level in the cleaning tank 22 is in a normal range at the same time, and the structure of the base station 20 is simplified.

Further, the float assembly 41 is provided at one side of the filtering device 40, so that good detection between the non-contact type sensing element and the non-contact type sensed element can be achieved, which is advantageous for improving detection accuracy.

The non-contact type sensed element or non-contact type sensing element provided on the float body 411 may be located inside or outside the float body 411 or other positions as required, and the embodiment of the present invention is not particularly limited.

In the above embodiment, the high water level value of the cleaning tank 22 is the first preset threshold value, and the specific range is less than or equal to the first preset threshold value, that is, when the surface of the liquid in the cleaning tank 22 is lower than or equal to the high water level value of the cleaning tank 22 and the filtering device 40 is installed in the cleaning tank 22, the non-contact sensing element can sense the non-contact sensed element, which means that the filtering device 40 is installed in the cleaning tank 22 of the base station body 21, and the water level in the cleaning tank 22 is lower than or equal to the high water level value, the liquid in the cleaning tank 22 will not affect the normal operation of the base station 20, for example, the dirt liquid in the cleaning tank 22 will not overflow risk, the dirt liquid in the cleaning tank 22 will not pollute the cleaning assembly 30, and the like, and at this time, the cleaning tank 22 can continuously accommodate sundries and dirt liquid.

On the contrary, when the filtering device 40 is not installed in the cleaning tank 22 of the base station body 21, or the filtering device 40 is installed in the cleaning tank 22 of the base station body 21, and the water level in the cleaning tank 22 is higher than the specific range, the non-contact sensing element cannot sense the non-contact sensed element, which indicates that the filtering device 40 is not installed in place, or the water level in the cleaning tank 22 is higher, there is a risk of affecting the normal operation of the base station 20, at this time, the user can be reminded of installing the filtering device 40 on the base station body 21, or stopping the sundries and the sewage from being thrown into the cleaning tank 22.

In the embodiment of the present invention, the high water level value of the cleaning tank 22 may be a fixed value, i.e., the first preset threshold may be a fixed value, such as 10mm, 20mm, 30mm, 50mm, or other values that meet the requirements of the cleaning tank 22. Alternatively, the high water level value of the cleaning tank 22 is related to the tank height of the cleaning tank 22, e.g., the high water level value of the cleaning tank 22 is 0.95 times, 0.90 times, 0.85 times, or other values as desired for the tank height of the cleaning tank 22.

In the above embodiment, the base station 20 further includes a controller, the cleaning assembly 30 further includes a liquid outlet device 34 electrically connected to the controller, and in the cleaning process of the cleaning member of the cleaning assembly 30 on the cleaning system 150 of the cleaning robot 10, the liquid outlet device 34 of the cleaning assembly 30 can work simultaneously, the liquid outlet device 34 sprays the cleaning liquid onto the cleaning system 150, and the cleaning system 150 is cleaned by using the impact force of the cleaning liquid, or the cleaning system 150 is infiltrated by using the cleaning liquid, so that the cleaning effect is improved in the cleaning process of the cleaning member on the cleaning system 150. Because the cleaning assembly 30 is located above the cleaning tank 22, the cleaning solution is contained in the cleaning tank 22 after the cleaning system 150 is cleaned.

It will be appreciated that the controller of the base station 20 may also interact with information of the cleaning robot 10 or a remote control terminal (APP) or the like. In this way, the controller can reasonably control the operation of other components of the cleaning system 150 according to the sensing result of the non-contact sensing element, such as controlling the operation state of the liquid outlet device 34 according to the sensing result, for example, when the non-contact sensing element can sense the non-contact sensed element, controlling the liquid outlet device 34 to continue to operate, and when the non-contact sensing element does not sense the non-contact sensed element, controlling the liquid outlet device 34 to stop operating, so as to prevent the liquid in the cleaning tank 22 from affecting the normal operation of the base station 20. Meanwhile, when the non-contact sensing element does not sense the non-contact sensed element, the controller can also send out a reminding signal to remind a user to check whether the filtering device 40 is installed in place, so that the reliability and safety of the operation of the base station 20 are greatly improved, and the device is suitable for popularization and application.
