Examples of the embodiments are shown in the drawings, where the same or similar reference numerals indicate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0030] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the applicability of other processes and / or the use of other materials.

[0031] Next, a base station 100 according to an embodiment of the present invention will be described with reference to the drawings.

[0032] As Figure 1 - Figure 2 and Figure 4As shown, the base station 100 according to an embodiment of the present utility model includes a sewage discharge device 2 and a filtering device 3; the sewage discharge device 2 is formed with a sewage inlet and a sewage outlet 2a, and the sewage discharge device 2 is further formed with a mounting opening 2b, and the mounting opening 2b is disposed at an interval between the sewage inlet and the sewage outlet 2a; the filtering device 3 is detachably mounted at the mounting opening 2b and extends into the sewage discharge device 2. Thus, the sewage flowing into the sewage discharge device 2 from the sewage inlet will be filtered by the filtering device 3 and discharged from the sewage outlet 2a, which can effectively reduce impurities in the sewage such as large-sized particles and hair, etc., and can reduce the collision or friction of the impurities in the sewage with the inner walls of the corresponding pipelines such as the pipeline connected to the sewage outlet 2a or components such as the first sewage discharge member or the third sewage discharge member 23 below during the sewage discharge process, and can, to a certain extent, avoid the accumulation and blockage of sundries in the corresponding pipelines or components, reduce the risk of blockage in the corresponding pipelines or components, and is beneficial to ensuring the smoothness of the sewage discharge process, thereby reducing the loss of the base station 100, and being beneficial to improving the service life and product quality of the base station 100. Secondly, the filtering device 3 is detachably mounted at the mounting opening 2b, which is convenient for the user to operate and handle the sundries collected by the filtering device 3, and improves the user experience.

[0033] For example, in combination with Figure 1 - Figure 2 and Figure 4 , taking the cooperation between the base station 100 and the cleaning device 101 as an example for illustration, the cleaning device 101 can be detachably cooperated with the base station 100. The cleaning device 101 includes a sewage tank 1011, and the sewage tank 1011 has a sewage discharge outlet. The sewage outlet 2a of the base station 100 is connected to the corresponding sewage pipeline, and the sewage pipeline discharges the sewage to the sewer. When the cleaning device 101 is placed on the base station 100, the cleaning device 101 cooperates with the base station 100, and the sewage discharge outlet of the sewage tank 1011 is communicated with the sewage inlet of the sewage discharge device 2. The sewage in the sewage tank 1011 will be transferred into the sewage discharge device 2. Then the sewage in the sewage tank 1011 flows from the sewage discharge outlet to the sewage inlet. The filtering device 3 in the sewage discharge device 2 filters the sundries in the sewage and collects them on the filtering device 3. The filtered sewage flows from the sewage outlet 2a to the sewage pipeline and then to the sewer, thereby reducing the blockage of the sewage pipeline and the sewer by the sundries in the sewage, avoiding the mildew, deterioration or peculiar smell caused by the retention or blockage of sundries to a certain extent, and reducing the damage of the sundries to the inner wall of the sewage pipeline, and improving the service life of the sewage pipeline.

[0034] In the above technical solution, by providing a detachable filtering device 3 inside the sewage discharge device 2, the sewage flowing into the sewage discharge device 2 from the sewage inlet is filtered by the filtering device 3 and then discharged from the sewage outlet 2a. This can effectively reduce the impurities in the sewage, reduce the collision or friction between the impurities in the sewage and the inner walls of the corresponding pipelines or components during the sewage discharge process, and to a certain extent avoid the accumulation and blockage of sundries in the corresponding pipelines or components, reducing the risk of blockage of the inner walls of the corresponding pipelines or components, facilitating the smooth sewage discharge process, thereby reducing the loss of the base station 100 and being beneficial to improving the service life and product quality of the base station 100. Secondly, the filtering device 3 is detachably installed at the installation port 2b, facilitating the user to operate and handle the sundries collected by the filtering device 3 and improving the user experience.

[0035] In some embodiments of the present application, relative to the sewage outlet 2a, the filtering device 3 is disposed adjacent to the first sewage outlet 2a; and / or, the filtering device 3 and the sewage discharge device 2 are connected by screw connection, threaded fastener connection, snap connection, or magnetic attraction connection.

[0036] In the description of the embodiments of the present application, the term "and / or" is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this article, the character " / " generally represents an "or" relationship between the associated objects before and after.

[0037] In some examples, relative to the sewage outlet 2a, the filtering device 3 is disposed adjacent to the first sewage outlet 2a. Thus, the filtering device 3 is adjacent to the sewage tank 1011, and the sewage discharged from the sewage tank 1011 can be filtered as soon as possible, which is beneficial to reducing the length of the sewage discharge flow path of the base station 100, reducing the damage length of the inner wall of the pipeline by the sundries in the sewage, and reducing the damage area of the base station 100, thereby being beneficial to improving the service life of the base station 100.

[0038] In some examples, the filtering device 3 and the sewage discharge device 2 are connected by screw connection, threaded fastener connection, snap connection, or magnetic attraction connection. Thus, the connection method between the filtering device 3 and the sewage discharge device 2 has various forms, facilitating adaptation to the application environment of the base station 100 and improving the applicability of the base station 100.

[0039] In some embodiments of the present application, the sewage discharge device 2 includes a first sewage discharge member 22. The first sewage discharge member 22 has a bottom wall 221 and a surrounding wall 222. The surrounding wall 222 is disposed around the bottom wall 221, and the installation port 2b is formed on the surrounding wall 222. The sewage discharge device 2 is configured such that the water flowing to the first sewage discharge member 22 flushes the surrounding wall 222 and / or the filtering device 3.

[0040] For example, in combination with Figure 1 andFigure 2 The first sewage discharge member 22 has a bottom wall 221 and a surrounding wall 222. The surrounding wall 222 is arranged around the bottom wall 221 so that the first sewage discharge member 22 is formed into a cavity structure. The position where sewage flows into the first sewage discharge member 22 from the sewage inlet is misaligned with the sewage outlet 2a. When the sewage flows from the sewage inlet to the sewage outlet 2a, the sewage rotates inside the first sewage discharge member 22 to wash the surrounding wall 222. Wherein, the installation opening 2b is formed on the surrounding wall 222, and the filtering device 3 extends into the sewage discharge device 2 from the installation opening 2b. The rotating sewage will also wash the filtering device 3, which is beneficial to improving the cleanliness of the filtering device 3.

[0041] In the above technical solution, by setting the water in the first sewage discharge member 22 to wash the surrounding wall 222 and / or the filtering device 3, it is possible to utilize the flow of sewage to achieve self-cleaning of the first sewage discharge member 22 or the filtering device 3, and reduce the deposition of sundries such as small-sized particles on the surrounding wall 222 or the filtering device 3, which is beneficial to improving the cleanliness of the first sewage discharge member 22 and the filtering device 3.

[0042] In some embodiments of the present application, in combination with Figure 1 the bottom wall 221 includes a first wall portion 2211 and a second wall portion 2212. The first wall portion 2211 is higher than the second wall portion 2212. A first cavity 2c is formed between the first wall portion 2211 and the surrounding wall 222, and a second cavity 2d is formed between the second wall portion 2212 and the surrounding wall 222. The first cavity 2c and the second cavity 2d are communicated and arranged in sequence along the liquid flow direction. The installation opening 2b is formed on the part of the surrounding wall 222 corresponding to the second cavity 2d. The filtering device 3 is arranged in the second cavity 2d, and at least part of the filtering device 3 is located below the first wall portion 2211.

[0043] For example, in combination with Figure 1 and Figure 2 the bottom wall 221 includes a first wall portion 2211 and a second wall portion 2212. The first wall portion 2211 is connected to the second wall portion 2212. A first cavity 2c is formed between the first wall portion 2211 and a part of the surrounding wall 222, and a second cavity 2d is formed between the second wall portion 2212 and another part of the surrounding wall 222. The first wall portion 2211 is higher than the second wall portion 2212, so part of the space of the second cavity 2d is lower than the first wall portion 2211. The first cavity 2c and the second cavity 2d are communicated and arranged in sequence along the liquid flow direction, so the sewage first passes through the first cavity 2c and then through the second cavity 2d. The installation opening 2b is formed on the part of the surrounding wall 222 corresponding to the second cavity 2d. The filtering device 3 can be installed in the installation opening 2b and extend into the second cavity 2d. The upper side edge of the filtering device 3 is flush with the first wall portion 2211, so that the filtering device 3 can be fitted into the space of the second cavity 2d lower than the first wall portion 2211, which can reduce the influence of the filtering device 3 on the sewage flow and is convenient for the filtering device 3 to collect the sundries in the sewage.

[0044] In the above technical solution, by arranging at least a part of the filtering device 3 below the first wall portion 2211, the influence of the filtering device 3 on the flow of sewage can be reduced, and it is convenient for the filtering device 3 to collect the sundries in the sewage.

[0045] In some embodiments of the present application, in combination with Figure 1 , a first communication port 222a is formed on the peripheral wall of the first chamber 2c. The first communication port 222a is located on a side of the first chamber 2c away from the second chamber 2d. A second communication port 221c is formed on the bottom wall 221 of the second chamber 2d. Among them, the first communication port 222a is configured as an inlet for sewage, or the first communication port 222a is communicated with the inlet for sewage, and the second communication port 221c is configured as a sewage discharge port 2a, or the second communication port 221c is communicated with the sewage discharge port 2a.

[0046] For example, in combination with Figure 1 , the bottom wall 221 includes a first wall portion 2211 and a second wall portion 2212. A first chamber 2c is formed between the first wall portion 2211 and the surrounding wall 222, and a second chamber 2d is formed between the second wall portion 2212 and the surrounding wall 222. A first communication port 222a is formed on the peripheral wall of the first chamber 2c. The first communication port 222a is located on a side of the first chamber 2c away from the second chamber 2d. A second communication port 221c is formed on the bottom wall 221 of the second chamber 2d. The first chamber 2c is communicated with the second chamber 2d, and the first chamber 2c and the second chamber 2d are arranged in sequence along the direction of sewage flowing from the first communication port 222a to the second communication port 221c. In this way, sewage flows into the first chamber 2c from the first communication port 222a, and then the sewage flows from the first chamber 2c to the second chamber 2d and flows out from the second communication port 221c.

[0047] Among them, the first communication port 222a and the second communication port 221c are spaced apart, and the second communication port 221c is formed on the bottom wall 221 of the second chamber 2d. The first wall portion 2211 is higher than the second wall portion 2212, so the second communication port 221c is lower than the first wall portion 2211. Therefore, when the sewage flows from the first communication port 222a towards the second communication port 221c, the sewage will form a vortex at the second communication port 221c to wash the surrounding wall 222 and the filtering device 3.

[0048] In the above technical solution, by arranging the first communication port 222a on a side of the first chamber 2c away from the second chamber 2d, and a second communication port 221c is formed on the bottom wall 221 of the second chamber 2d, when the sewage flows from the first communication port 222a towards the second communication port 221c, the sewage will form a vortex or the like at the second communication port 221c to wash the surrounding wall 222 and the filtering device 3, so as to realize the self-cleaning of the first sewage discharge member 22 and the filtering device 3.

[0049] Optionally, in combination with Figure 1 andFigure 2 Part of the side wall of the second chamber 2d is in limiting cooperation with the filtering device 3, and the second communication port 221c is located below the filtering device 3. Thus, part of the side wall of the second chamber 2d can carry and limit the filtering device 3, ensuring the stability of the filtering device 3 disposed in the first sewage discharge member 22, so that the cooperation between the filtering device 3 and the sewage discharge device 2 is more compact. At the same time, the sewage flowing to the second communication port 221c can first pass through the filtering device 3, which can improve the sewage filtering and collection capacity of the base station 100 and enhance the applicability of the base station 100.

[0050] In some embodiments of the present application, the second communication port 221c is arranged towards the side where the first chamber 2c is located. Thus, when the sewage in the first chamber 2c flows towards the second communication port 221c, it is beneficial for the sewage to flow into the second communication port 221c better, which can reduce the loss of the flowing energy of the sewage and is conducive to improving the self-cleaning effect of the sewage.

[0051] In some embodiments of the present application, combined with Figure 1 , the first wall portion 2211 and the second wall portion 2212 are arranged in sequence along the first horizontal direction, the installation port 2b is formed on one side of the surrounding wall 222 in the second horizontal direction, the size of the filtering device 3 in the first horizontal direction is smaller than its size in the second horizontal direction, and the filtering device 3 is configured to be insertable into the installation port 2b along the second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction.

[0052] For example, combined with Figure 1 , taking the first horizontal direction as the front-back direction and the second horizontal direction as the left-right direction as an example for illustration. The first wall portion 2211 and the second wall portion 2212 are arranged in sequence along the front-back direction. A first chamber 2c is formed between the first wall portion 2211 and the surrounding wall 222, a second chamber 2d is formed between the second wall portion 2212 and the surrounding wall 222, the first chamber 2c and the second chamber 2d are communicated and arranged in sequence along the front-back direction, the installation port 2b is formed on the part of the surrounding wall 222 corresponding to the second chamber 2d, and the installation port 2b is located on the right side part of the surrounding wall 222.

[0053] Wherein, the size of the filtering device 3 in the front-back direction is smaller than its size in the left-right direction, and the filtering device 3 can be inserted into the installation port 2b along the left-right direction. Thus, the cooperation between the filtering device 3 and the first sewage discharge member 22 in the front-back direction is compact, which can reduce the space occupied by the filtering device 3 in the first sewage discharge member 22 in the front-back direction to reduce the influence of the filtering device 3 on the flow of sewage.

[0054] In the above technical solution, by setting the size of the filtering device 3 in the first horizontal direction to be smaller than its size in the second horizontal direction, and the filtering device 3 is configured to be insertable into the mounting opening 2b along the second horizontal direction, the filtering device 3 and the first sewage discharge member 22 are tightly matched in the front-rear direction, which can reduce the space occupied by the filtering device 3 in the first sewage discharge member 22 in the front-rear direction, so as to reduce the influence of the filtering device 3 on the flow of sewage.

[0055] In some embodiments of the present application, in combination with Figure 1 and Figure 2 , a filtering groove 31b is formed by the part of the filtering device 3 extending into the first sewage discharge member 22 being recessed toward the second wall portion 2212, and a plurality of spaced-apart outlets 312 are formed at the bottom of the filtering groove 31b. Thus, the filtering device 3 can collect debris in the sewage through the filtering groove 31b, and the debris can be processed by disassembling and assembling the filtering device 3.

[0056] In some embodiments of the present application, in combination with Figure 2 , the filtering device 3 includes a filtering structure 31 and a mounting structure 32. The mounting structure 32 is provided at one end of the filtering structure 31 and is fitted to the mounting opening 2b. The filtering structure 31 is provided in the sewage discharge device 2, and the other end of the filtering structure 31 abuts against the inner side wall of the sewage discharge device 2 opposite to the mounting opening 2b.

[0057] For example, in combination with Figure 2 , the mounting structure 32 cooperates with the mounting opening 2b. A threaded structure is formed on the outer peripheral wall of the mounting structure 32, and a threaded structure is also formed on the inner side wall surface of the mounting opening 2b. Thus, the mounting structure 32 can be operated to dispose the filtering structure 31 in the sewage discharge device 2, and the mounting structure 32 can be threadedly engaged with the inner side wall surface of the mounting opening 2b to stably mount the filtering structure 31 on the mounting opening 2b.

[0058] Optionally, in combination with Figure 2 , the mounting structure 32 is provided at one length end of the filtering structure 31. The mounting structure 32 includes an operation part 321 and a sealing part 322. The sealing part 322 is formed as a circular structure and is connected to the filtering structure 31. The sealing part 322 can abut and cooperate with the inner side wall of the mounting opening 2b to achieve sealing between the mounting structure 32 and the side wall of the mounting opening 2b. The operation part 321 is located on the side of the sealing part 322 away from the filtering structure 31. The user can operate the mounting structure 32 through the operation part 321 to control the filtering device 3 to pass through the mounting opening 2b and be mounted in the sewage discharge device 2.

[0059] In the above technical solution, by setting the mounting structure 32 to cooperate with the mounting opening 2b, and the other end of the filtering structure 31 abuts against the inner side wall of the sewage discharge device 2 opposite to the mounting opening 2b, the filtering device 3 can be stably mounted on the sewage discharge device 2.

[0060] Optionally, in combination with Figure 1 , the filtering structure 31 includes a cylindrical portion 31a. A filtering groove 31b is formed in the cylindrical portion 31a. An inlet 311 and a plurality of spaced-apart outlets 312 are formed in the peripheral wall of the cylindrical portion 31a. The opening area of the inlet 311 is larger than the opening area of the outlet 312. Thus, by setting the opening area of the inlet 311 to be larger than the opening area of the outlet 312, it is convenient for sewage to flow smoothly into the inlet 311, and the plurality of outlets 312 formed in the cylindrical portion 31a cause the cylindrical portion 31a to be formed into a structure similar to a net structure, so that the cylindrical portion 31a can filter debris in the sewage and collect the debris in the cylindrical portion 31a.

[0061] For example, in combination with Figure 2 , the filtering structure 31 includes a cylindrical portion 31a. The upper side edge of the peripheral wall of the cylindrical portion 31a forms an inlet 311. The peripheral wall of the cylindrical portion 31a also forms a plurality of spaced-apart outlets 312. The opening area of the inlet 311 is larger than the opening area of all the outlets 312, so that the cylindrical portion 31a is formed into a structure similar to a net structure, so that there is a certain accommodation space in the cylindrical portion 31a, so that the cylindrical portion 31a can filter debris in the sewage and collect the debris in the cylindrical portion 31a.

[0062] Optionally, in combination with Figure 1 and Figure 2 , the edge of the filtering structure 31 is flush with the edge of the first wall portion 2211, which can reduce the influence of the filtering structure 31 on the flow of sewage and is beneficial to improving the self-cleaning effect of the sewage discharge device 2.

[0063] Optionally, in combination with Figure 2 , the base station 100 further includes a sealing ring 4.

[0065] In some embodiments of the present application, in combination with Figure 1 and Figure 2 , the surrounding wall 222 includes a first side wall 2221 and a second side wall 2222. A first communication port 222a is formed on the first side wall 2221. The second side wall 2222 includes a third wall portion 2222a and a fourth wall portion 2222b. The third wall portion 2222a corresponds to the first chamber 2c, and the fourth wall portion 2222b corresponds to the second chamber 2d. An installation port 2b is formed on the fourth wall portion 2222b. The fourth wall portion 2222b is recessed into the first sewage discharge member 22 relative to the third wall portion 2222a until the fourth wall portion 2222b is opposite to the first communication port 222a.

[0066] For example, in combination with Figure 1 and Figure 2 , the first side wall 2221 is connected to the second side wall 2222, and a first communication port 222a is formed on the first side wall 2221. The first communication port 222a is communicated with the sewage inlet. The second side wall 2222 includes a connected third wall portion 2222a and a fourth wall portion 2222b. The third wall portion 2222a is connected to the first side wall 2221. The fourth wall portion 2222b is located on the side of the third wall portion 2222a away from the first side wall 2221, and a part of the fourth wall portion 2222b opposite to the first communication port 222a of the surrounding wall 222 is connected. The third wall portion 2222a corresponds to the first chamber 2c, and the fourth wall portion 2222b corresponds to the second chamber 2d. The fourth wall portion 2222b is recessed inward relative to the third wall portion 2222a, that is, the fourth wall portion 2222b is recessed into the second chamber 2d relative to the third wall portion 2222a, so that the connected part of the third wall portion 2222a and the fourth wall portion 2222b is opposite to the first communication port 222a. Thus, the sewage flowing into the first sewage discharge member 22 from the first communication port 222a will act on the fourth wall portion 2222b, and the sewage rotates in the first sewage discharge member 22 so that the water flow flushes and cleans the surrounding wall 222, thereby improving the self-cleaning ability of the sewage to the surrounding wall 222. To a certain extent, it can avoid the accumulation or adhesion of sundries on the surrounding wall 222, which may cause mildew, deterioration or peculiar smell, etc., reduce the breeding of bacteria, and improve the cleanliness of the first sewage discharge member 22. Of course, when the sewage rotates in the first sewage discharge member 22, the water flow can flush and clean the filtering device 3 to realize the self-cleaning of the filtering device 3.

[0067] In the above technical solution, by setting the fourth wall portion 2222b to be recessed into the first sewage discharge member 22 relative to the third wall portion 2222a until the fourth wall portion 2222b is opposite to the first communication port 222a, the sewage flowing from the first sewage discharge member 22 to the first sewage discharge member 22 will act on the fourth wall portion 2222b, and the sewage rotates in the first sewage discharge member 22, so that the water flow flushes and cleans the surrounding wall 222, thereby realizing the self-cleaning effect of the surrounding wall 222.

[0068] In some embodiments of the present application, in combination with Figure 1 and Figure 2 , the sewage discharge device 2 includes a first sewage discharge member 22 and a second sewage discharge member 21. The second sewage discharge member is configured as a tubular structure and has a sewage inlet formed at one end. The first sewage discharge member is connected to the end of the second sewage discharge member away from the sewage inlet, and the flow area of the first sewage discharge member is larger than that of the second sewage discharge member. The installation port 2b is formed on the first sewage discharge member.

[0069] In the above technical solution, by setting the flow area of the first sewage discharge member to be larger than that of the second sewage discharge member, it is convenient for sewage to flow quickly from the second sewage discharge member into the first sewage discharge member, which is beneficial to improving the sewage discharge efficiency of the sewage in the sewage tank 1011. Secondly, the installation port 2b is formed on the first sewage discharge member, and the flow area of the first sewage discharge member is relatively large, which is beneficial for the first sewage discharge member to have a suitable space for accommodating the filtering device 3, and is beneficial for the filtering device 3 to have a relatively large volume for collecting sundries, reducing the replacement or cleaning frequency of the filtering device 3, thereby being beneficial to improving the sewage discharge effect of the base station 100 and the sundries collection amount of the filtering device 3.

[0070] Optionally, in combination with Figure 1 , the first sewage discharge member 22 is formed as a cavity structure, and the volume of the first sewage discharge member 22 is larger than that of the second sewage discharge member 21, so that the first sewage discharge member 22 has a certain storage capacity. When the filtering device 3 filters sewage, the flow rate of the sewage will be slowed down so that the first sewage discharge member 22 can store a certain amount of sewage, ensuring the normal sewage discharge of the base station 100.

[0071] Optionally, in combination with Figure 1 and Figure 2 , the sewage discharge device 2 includes a third sewage discharge member 23. The third sewage discharge member 23 is configured as a tubular structure, and a sewage discharge port 2a is formed at one end of the third sewage discharge member 23. The other end of the third sewage discharge member 23 is connected to the bottom wall 221 of the second cavity 2d and communicates with the second communication port 221c. Among them, the third sewage discharge member 23 is located below the bottom wall 221, and the included angle between the third sewage discharge member 23 and the bottom wall 221 is an acute angle. Thus, the sewage in the first sewage discharge member 22 first passes through the filtering device 3, and then flows into the third sewage discharge member 23 through the second communication port 221c and flows towards the sewage discharge port 2a, which is beneficial to improving the spinning effect of the sewage in the first sewage discharge member 22, improving the self-cleaning ability of the first sewage discharge member 22 using sewage, and the filtering device 3 can effectively filter the sundries in the sewage.

The cleaning device 101 is detachably cooperated with the base station 100. The cleaning device 101 includes a sewage tank 1011. A sewage discharge outlet is formed in the sewage tank 1011, and the sewage discharge outlet is communicated with the sewage inlet. Thus, the sewage in the cleaning device 101 can flow to the sewage discharge device 2 through the sewage discharge outlet to achieve sewage discharge and filtration treatment of the sewage.

[0073] In the above technical solution, by adopting the above base station 100, the service life of the cleaning system 200 can be improved.
