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.

[0043] The water supply and drainage module 10 according to the first aspect embodiment of the present invention will be described below with reference to the drawings.

[0044] As Figures 1 to 5As shown, the water supply and drainage module 10 according to the first aspect embodiment of the present utility model is used for cleaning the base station 20. The cleaning base station 20 has a first water inlet joint 20a and a first sewage discharge joint 20b. The water supply and drainage module 10 is detachably connected to the cleaning base station 20 and is located outside the cleaning base station 20. That is to say, the water supply and drainage module 10 can be installed on the cleaning base station 20 to enable the cleaning base station 20 to have the function of water supply and drainage. Users can flexibly choose whether to install the water supply and drainage module 10 according to their usage requirements. In addition, since the water supply and drainage module 10 is located outside the cleaning base station 20, it can avoid the water supply and drainage module 10 occupying the internal space of the cleaning base station 20, and at the same time, it can reduce the difficulty of installing the water supply and drainage module 10 on the cleaning base station 20, such as without having to disassemble the casing 6 of the cleaning base station 20 to put the water supply and drainage module 10 into the inside of the cleaning base station 20.

[0045] The water supply and drainage module 10 includes: a housing 1, a water inlet unit 2 and a sewage discharge unit 3. The water inlet unit 2 is arranged in the housing 1 and includes a water inlet pipeline 21. One end of the water inlet pipeline 21 has a second water inlet joint 211 adapted to be connected to an external water source, and the other end of the water inlet pipeline 21 has a third water inlet joint 212 adapted to be connected to the first water inlet joint 20a. That is to say, the water inlet pipeline 21 is connected to the cleaning base station 20 through the connection of the third water inlet joint 212 and the first water inlet joint 20a, so that a connected flow path can be formed among the external water source, the water inlet pipeline 21 and the cleaning base station 20. The water flow at the external water source can enter the cleaning base station 20 through the water inlet pipeline 21 to inject clean water into the cleaning base station 20. That is, the water supply and drainage module 10 can add a water supply function to the cleaning base station 20 through the water inlet unit 2. Among them, the external water source can be a faucet, a water pipe, etc. that can provide water flow, and no specific limitation is made here.

[0046] The sewage discharge unit 3 is arranged in the housing 1 and includes a sewage discharge pipeline 31 and a sewage pump 32 arranged on the sewage discharge pipeline 31. One end of the sewage discharge pipeline 31 has a second sewage discharge joint 311 for discharging sewage, and the other end of the sewage discharge pipeline 31 has a third sewage discharge joint 312 adapted to be connected to the first sewage discharge joint. That is to say, the sewage discharge pipeline 31 is connected to the cleaning base station 20 through the connection of the third sewage discharge joint 312 and the first sewage discharge joint 20b, and the second sewage discharge joint 311 can be connected to a sewage discharge channel such as a sewer, so that a connected flow path can be formed among the cleaning base station 20, the sewage discharge pipeline 31 and the sewer. The sewage pump 32 can apply a driving force to the sewage in the cleaning base station 20 through the sewage discharge pipeline 31, and the sewage in the cleaning base station 20 is discharged into the sewer through the sewage discharge pipeline 31 under the drive of the sewage pump 32. That is, the water supply and drainage module 10 can add a sewage discharge function to the cleaning base station 20 through the sewage discharge unit 3.

[0047] Thus, the user can install the water supply and drainage module 10 on the cleaning base station 20 according to the usage requirements to add an automatic water supply and drainage function to the cleaning base station 20. That is, on the basis of the original cleaning base station 20, the user only needs to purchase the water supply and drainage module 10 and install it, so as to save the cost of the user purchasing an additional cleaning base station 20 with an automatic water supply and drainage function, and further reduce the transformation cost of the cleaning base station 20. In addition, the water supply and drainage module 10 is located outside the cleaning base station 20, with low installation difficulty and convenient for later maintenance.

[0048] The water supply and drainage module 10 according to the first aspect embodiment of the present invention is detachably connected to the cleaning base station 20. The user can install the water supply and drainage module 10 on the cleaning base station 20 according to the usage requirements to add an automatic water supply and drainage function to the cleaning base station 20, so as to save the cost of the user purchasing an additional cleaning base station 20 with an automatic water supply and drainage function, and further reduce the transformation cost of the cleaning base station 20. In addition, the water supply and drainage module 10 is located outside the cleaning base station 20, with low installation difficulty and convenient for later maintenance.

[0049] In some embodiments, the second water inlet joint 211 is communicated with an external water source through a three-way valve 60. One of the other two water outlets of the three-way valve 60 is connected to a water pipe, and the other of the other two water outlets of the three-way valve 60 is connected to a faucet, so as to ensure that the water pipe can supply water to the water supply and drainage module 10 while ensuring the normal use of the faucet.

[0050] According to some embodiments of the present invention, the water inlet unit 2 further includes a first control valve 22 provided on the water inlet pipeline 21. The first control valve 22 is used to control the on-off of the water inlet pipeline 21. That is to say, the on-off of the water inlet pipeline 21 can be controlled by the on-off of the first control valve 22, so that the water inlet unit 2 can flexibly control the water addition and stop the water addition according to the water usage requirements of the cleaning base station 20. Specifically, when it is necessary to add water to the cleaning base station 20, the first control valve 22 is controlled to be in a conducting state, that is, the water inlet pipeline 21 is in a conducting state at this time, so as to form a connected water flow channel between the external water source, the water inlet pipeline 21 and the cleaning base station 20, and the water flow at the external water source can enter the cleaning base station 20 through the water inlet pipeline 21 to realize water supply; when the cleaning base station 20 does not need to add water, the first control valve 22 is controlled to be in a cut-off state, that is, the water inlet pipeline 21 is in a cut-off state at this time, so as to cut off the connection between the external water source and the cleaning base station 20 to avoid waste caused by water overflow. In a specific example, the first control valve 22 is a solenoid valve, and the first control valve 22 is electrically connected to the first circuit board 5 of the water supply and drainage module 10.

[0051] According to some embodiments of the present utility model, the water inlet unit 2 further includes a pressure reducing valve 23, and the pressure reducing valve 23 is arranged in the water inlet pipeline 21. Among them, the pressure reducing valve 23 can preferably adjust the water pressure in the water inlet pipeline 21 to make the water pressure stable. For example, when the external water source is a water pipe, the water pressure in the water pipe is relatively high, and the pressure reducing valve 23 can reduce the water pressure in the water inlet pipeline 21, thereby avoiding the impact on the components downstream of the water inlet pipeline 21 caused by too high water pressure, which is beneficial to improving the safety performance of the water supply and drainage module 10 during use.

[0052] According to some embodiments of the present utility model, the pressure reducing valve 23 is located on the upstream side of the first control valve 22. That is, after the external water source enters the water inlet pipeline 21, it first flows through the pressure reducing valve 23 and then through the first control valve 22. In other words, the external water source has been depressurized by the pressure reducing valve 23 before flowing to the first control valve 22. It can be understood that when the first control valve 22 is in the conducting state, the greater the water pressure flowing through the first control valve 22, the greater the resistance to closing the first control valve 22, and the more difficult it is for the first control valve 22 to switch to the cut-off state. Therefore, by arranging the pressure reducing valve 23 on the upstream side of the first control valve 22, the risk of the first control valve 22 being difficult to close and leaking due to too high external water source pressure can be avoided, thereby ensuring the stable operation of the first control valve 22 and being beneficial to improving the reliability of the water inlet unit 2.

[0053] According to some embodiments of the present utility model, the sewage discharge unit 3 further includes a check valve 33, and the check valve 33 is arranged in the sewage discharge pipeline 31 and is unidirectionally conductive in the direction from the third sewage discharge joint 312 to the second sewage discharge joint 311. That is to say, the sewage located on the upstream side of the check valve 33 in the sewage discharge pipeline 31 can flow through the check valve 33 to the downstream side of the check valve 33, and the sewage on the downstream side of the check valve 33 cannot flow through the check valve 33 towards the upstream side of the check valve 33. Thus, the reverse flow of sewage can be preferably avoided to improve the stability of sewage discharge of the sewage discharge unit 3, and at the same time, the risk of pollution caused by the reverse flow of sewage in the sewage discharge pipeline 31 can be reduced.

[0054] According to some embodiments of the present utility model, the check valve 33 is located on the downstream side of the sewage pump 32 and is arranged adjacent to the second sewage discharge joint 311. That is to say, the sewage in the sewage discharge pipeline 31 first flows through the sewage pump 32 and then flows through the check valve 33 to the second sewage discharge joint 311 during the discharge process, and the check valve 33 is located between the sewage pump 32 and the second sewage discharge joint 311. It can be understood that the second sewage discharge joint 311 is connected to a sewage discharge pipeline such as a sewer. Thus, the check valve 33 can preferably block the reverse flow of sewage into the sewage pump 32, and at the same time, can preferably reduce the residual sewage in the sewage discharge pipeline 31, thereby reducing the risk of pollution caused by the connection of sewage in the sewage discharge pipeline 31.

[0055] According to some embodiments of the present utility model, the water inlet pipeline 21 extends along the first direction e1, and the water inlet unit 2 and the sewage discharge unit 3 are arranged along the second direction e2, and the second direction e2 is perpendicular to the first direction e1. Thus, the water inlet unit 2 and the sewage discharge unit 3 can make full use of the space inside the housing 1 in the second direction e2, with a compact structure. At the same time, the interference risk during the installation of the water inlet unit 2 and the sewage discharge unit 3 can be reduced, which is beneficial to improving the assembly efficiency of the water supply and drainage module 10.

[0056] According to some embodiments of the present utility model, the second water inlet joint 211 and the second sewage discharge joint 311 are located on different sides of the housing 1. Thus, the second water inlet joint 211 and the second sewage discharge joint 311 are exposed outside the housing 1, facilitating the connection of the second water inlet joint 211 and the second sewage discharge joint 311. At the same time, the distance between the second water inlet joint 211 and the second sewage discharge joint 311 can be preferably increased, so that a larger operating space can be provided for the connection of the second water inlet joint 211 to an external water source and the connection of the second sewage discharge joint 311 to a sewer. Moreover, since the second water inlet joint 211 is connected to an external water source such as a faucet and a water pipe, and the second sewage discharge joint 311 is communicated with a sewage discharge pipe such as a sewer, and the external water source and the sewer are usually in different positions. For example, the sewer is usually arranged on the ground, while the faucet and the like are usually arranged on the wall surface. Arranging the second water inlet joint 211 and the second sewage discharge joint 311 on different sides of the housing 1 facilitates the connection of the water supply and drainage module 10 to the external water source and the sewer in different positions, which is beneficial to reducing the installation difficulty of the water supply and drainage module 10.

[0057] According to some embodiments of the present utility model, the third water inlet joint 212 and the third sewage discharge joint 312 are located on the same side of the housing 1. Among them, both the third water inlet joint 212 and the third sewage discharge joint 312 are used to connect to the cleaning base station 20. Therefore, during the assembly process of the water supply and drainage module 10 and the cleaning base station 20, there is no need to turn over the water supply and drainage module 10. For example, when the side where the third water inlet joint 212 and the third sewage discharge joint 312 are arranged faces upward, the installer can see both the third water inlet joint 212 and the third sewage discharge joint 312 at the same time, and the installer can sequentially connect the third water inlet joint 212 to the first water inlet joint 20a and the third sewage discharge joint 312 to the first sewage discharge joint 20b, which is beneficial to improving the installation efficiency of the water supply and drainage module 10.

[0058] According to some embodiments of the present utility model, the water supply and drainage module 10 further includes: a first electronic control board, and the sewage pump 32 is electrically connected to the first electronic control board, so that the sewage pump 32 can be powered and an instruction to start or stop can be sent to the sewage pump 32 through the first electronic control board to control the switching of the sewage discharge unit 3 between the standby state and the sewage discharge state. A docking interface 51 is formed on the first electronic control board, and the cleaning base station 20 has a second electronic control board, and the docking interface 51 is adapted to be electrically connected to the second electronic control board. That is to say, after the water supply and drainage module 10 is installed on the cleaning base station 20, the first electronic control board is electrically connected to the second electronic control board through the docking interface 51, so that the second electronic control board can transmit current and control signals to the first electronic control board, and then the sewage pump 32 can be controlled through the first electronic control board. Thus, the cost of the device for powering the water supply and drainage module 10 can be preferably saved, and at the same time, communication between the water supply and drainage module 10 and the cleaning base station 20 can be realized through the electrical connection between the first circuit board 5 and the second circuit board, so that the water supply and drainage module 10 can be adjusted to the corresponding state according to the operating state of the cleaning base station 20 to ensure the operation of the cleaning base station 20. In a specific example, the first control valve 22 is electrically connected to the first circuit board 5 to control the sewage discharge valve and the first control valve 22 through the first circuit board 5 at the same time.

[0059] Specifically, a cooperation bin 61 for cooperating with a cleaning device 200 such as a sweeping robot is formed in the cleaning base station 20, and a cleaning tank for cleaning a mopping member of the cleaning device 200 is provided in the cooperation bin 61. When the cleaning base station 20 is short of water, the second circuit board transmits a water supply signal to the first circuit board 5, and the first circuit board 5 controls the water inlet unit 2 to supply water to the cleaning base station 20; when it is necessary to discharge the sewage in the cleaning base station 20, the second circuit board transmits a sewage discharge signal to the first circuit board 5, and the first circuit board 5 controls the sewage discharge unit 3 to extract and discharge the sewage in the cleaning base station 20.

[0060] According to some embodiments of the present utility model, the docking interface 51, the second water inlet joint 211, and the second sewage discharge joint 311 are located on different sides of the housing 1. Thus, the docking interface 51, the second water inlet joint 211, and the second sewage discharge joint 311 are exposed on the outside of the housing 1, facilitating the connection of the docking interface 51, the second water inlet joint 211, and the second sewage discharge joint 311. At the same time, the distance between the docking interface 51, the second water inlet joint 211, and the second sewage discharge joint 311 can be preferably increased, so as to provide a larger operating space for the connection between the docking interface 51 and the cleaning base station 20, the connection between the second water inlet joint 211 and an external water source, and the connection between the second sewage discharge joint 311 and a sewer. Moreover, the cleaning base station 20, the external water source, and the sewer are usually in different positions. By arranging the docking interface 51, the second water inlet joint 211, and the second sewage discharge joint 311 on different sides of the housing 1, it is convenient for the water supply and drainage module 10 to be connected to the cleaning base station 20, the external water source, and the sewer in different positions, which is conducive to reducing the installation difficulty of the water supply and drainage module 10.

[0061] According to some embodiments of the present utility model, the docking interface 51, the third water inlet joint 212, and the third sewage discharge joint 312 are located on the same side of the housing 1. Among them, the docking interface 51, the third water inlet joint 212, and the third sewage discharge joint 312 are all used to connect to the cleaning base station 20. Therefore, during the assembly process of the water supply and drainage module 10 and the cleaning base station 20, there is no need to turn over the water supply and drainage module 10. For example, when the side where the docking interface 51, the third water inlet joint 212, and the third sewage discharge joint 312 are arranged faces upward, the installer can see the third water inlet joint 212 and the third sewage discharge joint 312 at the same time. Then the installer can sequentially connect the docking interface 51 to the second circuit board, connect the third water inlet joint 212 to the first water inlet joint 20a, and connect the third sewage discharge joint 312 to the first sewage discharge joint 20b, which is conducive to improving the installation efficiency of the water supply and drainage module 10.

[0062] According to some embodiments of the present utility model, the sewage discharge pipeline 31 is in an L shape. A receiving space is defined between the sewage discharge pipeline 31 and the inner side surface of the housing 1. The first electronic control board is arranged in the receiving space, and the sewage pump 32 is located outside the receiving space. That is to say, the first electronic control board and the sewage pump 32 are respectively located on the inner and outer sides of the receiving space. Thus, the distance between the first electronic control board and the sewage pump 32 can be preferably increased, so as to reduce the interference between the first electronic control board and the sewage pump 32 during the installation process, which is conducive to improving the assembly efficiency of the water supply and drainage module 10.

[0063] According to some embodiments of the utility model, the upper and lower water modules 10 also include: a cleaning liquid supply unit arranged in the shell 1, the cleaning liquid supply unit includes a liquid storage tank 41, a liquid supply pipeline 42 and a liquid supply pump 43, the liquid storage tank 41 is used to store the cleaning liquid, one end of the liquid supply pipeline 42 is connected to the liquid storage tank 41, the cleaning base station 20 has a first liquid supply connector 20c, the other end of the liquid supply pipeline 42 has a second liquid supply connector 421 suitable for connecting to the first liquid supply connector 20c, and the liquid supply pump 43 is arranged in the liquid supply pipeline 42. That is, the liquid supply pipeline 42 is connected between the liquid storage tank 41 and the second liquid supply connector 421, and the liquid supply pipeline 42 is connected to the cleaning base station 20 through the connection between the second liquid supply connector 421 and the first liquid supply connector 20c. The liquid supply pump 43 is used to drive the cleaning liquid in the liquid supply pipeline 42 to flow from the liquid storage tank 41 toward the second liquid supply connector 421. Therefore, when the liquid supply pump 43 is turned on, a connected liquid flow path is formed between the liquid storage tank 41, the liquid supply pipeline 42 and the cleaning base station 20, so that the cleaning liquid in the liquid storage tank 41 can be transported toward the cleaning base station 20 through the liquid supply pipeline 42 under the drive of the liquid supply pump 43. In other words, the upper and lower water modules 10 can replenish the cleaning liquid for the cleaning base station 20 through the cleaning liquid supply unit, so as to improve the cleaning efficiency and effect of the cleaning base station 20 on the mopping and wiping parts through the cleaning liquid entering the cleaning base station 20.

[0064] In a specific example, a adding port 411 is formed on the liquid storage tank 41 , and the adding port 411 and the second water inlet connector 211 are located on the same side of the housing 1 .

[0065] According to some embodiments of the utility model, the water inlet pipeline 21 extends along the first direction e1, the liquid storage tank 41 is located on one side of the water inlet unit 2 in the second direction e2, the second direction e2 is perpendicular to the first direction e1, and the sewage unit 3 and the liquid supply pump 43 are located on the side of the water inlet unit 2 away from the liquid storage tank 41 in the second direction e2. That is to say, in the second direction e2, the sewage unit 3 and the liquid storage tank 41 are located on opposite sides of the water inlet unit 2, and the liquid supply pump 43 and the liquid storage tank 41 are also located on opposite sides of the water inlet unit 2. As a result, the water inlet unit 2, the sewage unit 3 and the cleaning liquid supply unit can make full use of the space in the second direction e2 in the housing 1, with a compact structure and a reasonable layout. At the same time, a larger installation space can be reserved for the liquid storage tank 41 on the side of the water inlet unit 2 away from the sewage unit 3 and the liquid supply pump 43, so that a larger volume of the liquid storage tank 41 can be installed on the side of the water inlet unit 2 away from the sewage unit 3 and the liquid supply pump 43, which is conducive to improving the ability of the upper and lower water modules 10 to store cleaning liquid, so as to reduce the frequency of adding cleaning liquid.

[0066] According to some embodiments of the present utility model, the water inlet unit 2 further includes a first control valve 22 provided on the water inlet pipeline 21. In the second direction e2, the first control valve 22 protrudes from the outer peripheral surface of the water inlet pipeline 21 in a direction away from the sewage discharge unit 3. An avoidance groove for avoiding the first control valve 22 is formed on the liquid storage tank 41, and at least a part of the first control valve 22 protruding from the outer peripheral surface of the water inlet pipeline 21 is located in the avoidance groove. Thus, the interference between the first control valve 22 and the liquid storage tank 41 can be preferably avoided through the avoidance groove, and at the same time, the space on the side of the water inlet pipeline 21 away from the liquid storage tank 41 in the second direction e2 occupied by the first control valve 22 can be avoided, and the internal structure of the water supply and drainage module 10 is compact.

[0067] According to some embodiments of the present utility model, the sewage discharge pipeline 31 includes a first pipe section extending along the first direction e1 and a second pipe section extending along the second direction e2. One end of the first pipe section is connected to one end of the second pipe section. The end of the first pipe section far from the second pipe section has a second sewage discharge joint 311. The other end of the second pipe section extends in a direction away from the water inlet unit 2 and has a third sewage discharge joint 312. An accommodation space is defined between the first pipe section and the second pipe section and the inner side surface of the housing 1 for the liquid supply pump 43 to be located in the accommodation space. That is to say, in the second direction e2, the first pipe section is located between the liquid supply pump 43 and the water inlet unit 2, and the liquid supply pump 43 is also located on the side of the second pipe section close to the third sewage discharge joint 312 in the first direction e1. Thus, the liquid supply pump 43 can make full use of the space at the included angle position of the first pipe section and the second pipe section, the compactness of the internal structure of the water supply and drainage module 10 can be improved, and thus the overall size of the water supply and drainage module 10 can be reduced to reduce the installation space occupied by the water supply and drainage module 10.

[0068] In a specific example, the sewage discharge pump 32 is connected to the connection position of the first pipe section and the second pipe section and is located outside the accommodation space.

[0069] According to some embodiments of the present utility model, the third water inlet joint 212, the third sewage discharge joint 312, and the second liquid supply joint 421 are located on the same side surface of the housing 1. Among them, the third water inlet joint 212, the third sewage discharge joint 312, and the second liquid supply joint 421 are all used for connecting with the cleaning base station 20. Therefore, during the assembly process of the water supply and drainage module 10 and the cleaning base station 20, there is no need to turn over the water supply and drainage module 10. For example, when the side surface where the third water inlet joint 212, the third sewage discharge joint 312, and the second liquid supply joint are arranged faces upward, the installer can see the third water inlet joint 212, the third sewage discharge joint 312, and the second liquid supply joint at the same time, and the installer can sequentially connect the third water inlet joint 212 with the first water inlet joint 20a, the third sewage discharge joint 312 with the first sewage discharge joint 20b, and the second liquid supply joint 421 with the first liquid supply joint 20c, which is beneficial to improving the installation efficiency of the water supply and drainage module 10.

[0070] According to some embodiments of the present utility model, the second water inlet joint 211, the second sewage discharge joint 311 and the second liquid supply joint 421 are located on different sides of the housing 1. Thus, the second water inlet joint 211, the second sewage discharge joint 311 and the second liquid supply joint 421 are exposed outside the housing 1, facilitating the connection of the second water inlet joint 211, the second sewage discharge joint 311 and the second liquid supply joint 421. At the same time, the distance between the second water inlet joint 211, the second sewage discharge joint 311 and the second liquid supply joint 421 can be better increased, so as to provide a larger operating space for the connection between the second water inlet joint 211 and an external water source, the connection between the second sewage discharge joint 311 and a sewer, and the connection between the second liquid supply joint 421 and the first liquid supply joint 20c. Moreover, the cleaning base station 20, the external water source and the sewer are usually in different positions. Setting the second water inlet joint 211, the second sewage discharge joint 311 and the second liquid supply joint 421 on different sides of the housing 1 facilitates the connection of the water supply and drainage module 10 to the cleaning base station 20, the external water source and the sewer in different positions, which is conducive to reducing the installation difficulty of the water supply and drainage module 10.

[0071] The base station assembly 100 according to the second aspect embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0072] The base station assembly 100 according to the second aspect embodiment of the present utility model includes: a water supply and drainage module 10 and a cleaning base station 20.

[0073] For the base station assembly 100 according to the second aspect embodiment of the present utility model, a user can install the water supply and drainage module 10 on the cleaning base station 20 according to usage requirements to add an automatic water supply and drainage function to the cleaning base station 20, thereby saving the cost for the user to purchase an additional cleaning base station 20 with an automatic water supply and drainage function, and further reducing the transformation cost of the cleaning base station 20. In addition, the water supply and drainage module 10 is located outside the cleaning base station 20, with low installation difficulty and convenient for later maintenance.

[0074] According to some embodiments of the present utility model, the cleaning base station 20 includes a housing 6, a water storage tank 7 and a sewage tank 8 disposed inside the housing 6. The first water inlet joint 20a is communicated with the water storage tank 7, and the first sewage discharge joint 20b is communicated with the sewage tank 8. Among them, the water storage tank 7 is used to store purified water, such as clean water or a mixture of clean water and cleaning liquid, and the sewage tank 8 is used to store the sewage generated inside the cleaning base station 20. That is to say, by connecting the first water inlet joint 20a and the third water inlet joint 212, a connected flow path can be formed between the water inlet pipeline 21 and the water storage tank 7, so that the water inlet unit 2 can add water into the water storage tank 7. Therefore, when the cleaning base station 20 uses water, such as when cleaning the mopping member of the cleaning device 200, it can pump water from the water storage tank 7 for use. It can be understood that the water pressure in the water storage tank 7 is stable, and the water pumping volume can be accurately controlled. In addition, by connecting the first sewage discharge joint 20b and the third sewage discharge joint 312, a connected flow path can be formed between the sewage discharge pipeline 31 and the sewage tank 8, so that the sewage discharge unit 3 can pump out the sewage in the sewage tank 8 and discharge it into the sewer. By storing the sewage generated by the cleaning base station 20 in the sewage tank 8, the opening times of the sewage pump 32 can be reduced, thereby reducing the power of the sewage pump 32.

[0075] According to some embodiments of the present utility model, both the first water inlet joint 20a and the first sewage discharge joint 20b are disposed on the outer surface of the housing 6. That is to say, both the first water inlet joint 20a and the first sewage discharge joint 20b are exposed on the outer surface of the housing 6, which is convenient for installers or users to operate the first water inlet joint 20a and the first sewage discharge joint 20b, and is beneficial to reducing the assembly efficiency of the cleaning base station 20 and the water supply and drainage module 10.

[0076] According to some embodiments of the present utility model, the first water inlet joint 20a and the first sewage discharge joint 20b are located on the same side of the housing 6. Among them, both the first water inlet joint 20a and the first sewage discharge joint 20b are used to connect with the water supply and drainage module 10. Therefore, during the assembly process of the water supply and drainage module 10 and the cleaning base station 20, there is no need to move the cleaning base station 20. For example, when the side of the cleaning base station 20 provided with the first water inlet joint 20a and the first sewage discharge joint 20b faces the installer, the installer can see both the first water inlet joint 20a and the first sewage discharge joint 20b, and the installer can sequentially connect the third water inlet joint 212 and the first water inlet joint 20a and connect the third sewage discharge joint 312 and the first sewage discharge joint 20b, which is beneficial to improving the installation efficiency of the water supply and drainage module 10 and the cleaning base station 20.

[0077] According to some embodiments of the present utility model, the base station assembly 100 further includes a water inlet connecting pipe 30 and a sewage discharge connecting pipe 40. The two ends of the water inlet connecting pipe 30 are respectively connected to the first water inlet joint 20a and the third water inlet joint 212, and the two ends of the sewage discharge connecting pipe 40 are respectively connected to the first sewage discharge joint 20b and the third sewage discharge joint 312. That is to say, the water supply and drainage module 10 is connected to the cleaning base station 20 through the water inlet connecting pipe 30 and the sewage discharge connecting pipe 40. A communicating flow path is formed between the water inlet pipeline 21 and the cleaning base station 20 through the water inlet connecting pipe 30. At the same time, a communicating flow is formed between the sewage discharge pipeline 31 and the cleaning base station 20 through the sewage discharge connecting pipe 40. The layout of the water inlet connecting pipe 30 and the sewage discharge connecting pipe 40 can be flexibly adjusted. For example, both the water inlet connecting pipe 30 and the sewage discharge connecting pipe 40 can be flexible hoses. Thus, by means of the water inlet connecting pipe 30 and the sewage discharge connecting pipe 40, the diversity of the installation position of the water supply and drainage module 10 can be better improved. For example, it can be installed on the outer side surface of the cleaning base station 20, can also be installed on the wall surface, and can also be installed on the cabinet body, etc. The installation distance only needs not to exceed the lengths of the water inlet connecting pipe 30 and the sewage discharge connecting pipe 40.

[0078] In a specific example, a liquid supply connecting pipe 50 is further included. The two ends of the liquid supply connecting pipe 50 are respectively connected to the first liquid supply joint 20c and the second liquid supply joint 421, so as to form a communicating flow between the liquid supply pipeline 42 and the cleaning base station 20 through the liquid supply connecting pipe 50.

[0079] According to some embodiments of the present utility model, the sewage tank 8 has a sewage discharge port 81 communicating with the first sewage discharge joint 20b. A second control valve 84 is provided at the sewage discharge port 81 inside the sewage tank 8. One end of the sewage discharge connecting pipe 40 away from the third sewage discharge joint 312 is detachably fitted with the sewage discharge port 81. When the sewage discharge connecting pipe 40 is fitted with the sewage discharge port 81, the sewage discharge connecting pipe 40 pushes the second control valve 84 to an open state for conducting the sewage discharge port 81; when the sewage discharge connecting pipe 40 is disengaged from the sewage discharge port 81, the second control valve 84 is in a cut-off state for closing the sewage discharge port 81. That is to say, the second control valve 84 can be synchronously switched to the conducting state when the sewage discharge connecting pipe 40 is fitted with the sewage discharge port 81, and can be switched to the cut-off state when the sewage discharge connecting pipe 40 is disengaged from the sewage discharge port 81. That is, the switching of the second control valve 84 between the conducting state and the cut-off state is controlled by the fitting and disengagement of the sewage discharge connecting pipe 40 and the sewage discharge port 81. Thus, a device for separately controlling the switching of the second control valve 84 between the conducting state and the cut-off state can be preferably omitted, which is beneficial to simplifying the structure of the cleaning base station 20. Specifically, when the sewage discharge connecting pipe 40 is fitted with the sewage discharge port 81, the second control valve 84 opens the sewage discharge port 81. Therefore, the sewage in the sewage tank 8 can enter the sewage discharge connecting pipe 40 through the sewage discharge port 81 and further be discharged through the sewage discharge unit 3. When the sewage discharge connecting pipe 40 is disengaged from the sewage discharge port 81, the second control valve 84 closes the sewage discharge port 81, thereby avoiding the overflow of the sewage in the sewage tank 8 through the sewage discharge port 81 and causing pollution.

[0080] In a specific example, when the sewage discharge connecting pipe 40 is fitted with the sewage discharge port 81, the sewage discharge connecting pipe 40 is inserted into the sewage tank 8, and a communication hole 40a is formed on the outer peripheral surface of the part of the sewage discharge connecting pipe 40 located inside the sewage tank 8. The water in the sewage tank 8 can enter the sewage discharge connecting pipe 40 through the communication hole 40a.

[0081] According to some embodiments of the present utility model, the second control valve 84 includes a valve core 841 and an elastic reset member 842. The elastic reset member 842 is provided on the side of the valve core 841 away from the sewage discharge port 81, and the elastic reset member 842 is used to drive the valve core 841 to move towards the cut-off state. That is to say, the elastic reset member 842 has a tendency to drive the valve core 841 to move towards the direction close to the sewage discharge port 81. Thus, when the sewage discharge connecting pipe 40 is disengaged from the sewage discharge port 81, that is, when the thrust acting on the valve core 841 by the sewage discharge connecting pipe 40 disappears, the elastic reset member 842 can stably push the valve core 841 close to the sewage discharge port 81 and finally close the sewage discharge port 81.

[0082] According to some embodiments of the present utility model, the sewage connection pipe 40 passes through the first sewage joint 20b and the sewage outlet 81. That is to say, the sewage connection pipe 40 is in plug-in fit with the first sewage joint 20b and the sewage outlet 81. The cooperation mode of the sewage connection pipe 40 with the first sewage structure and the sewage outlet 81 is simple, which is convenient for installation or disassembly. At the same time, it is convenient for the sewage connection pipe 40 to extend into the sewage outlet 81 to cooperate with the second control valve 84, so as to ensure that the sewage connection pipe 40 can control the second control valve 84 to be in a conducting state after being fitted with the sewage outlet 81. In a specific example, the first sewage joint 20b is formed as a through hole penetrating the housing 6 and is opposite to and communicated with the sewage outlet 81. The sewage tank 8 and the water storage tank 7 are arranged along the second direction e2. In the second direction e2, the sewage outlet 81 is located on the side of the sewage tank 8 facing away from the water storage tank 7, so that the opening length of the first sewage joint 20b can be shortened, and further the difficulty of inserting the sewage connection pipe 40 into the sewage outlet 81 through the first sewage joint 20b can be reduced.

[0083] According to some embodiments of the present utility model, a water filling port 71, a liquid adding port 72 and a water pumping port 73 are formed on the water storage tank 7. The cleaning base station 20 further includes a water pump, a first communication pipe 91 and a second communication pipe 92. A cleaning tank for cleaning the mopping member of the cleaning device 200 is provided in the cleaning base station 20. The water inlet of the water pump is communicated with the water pumping port 73 and is used for pumping the liquid in the water storage tank 7 into the cleaning tank to clean the mopping member. One end of the first communication pipe 91 is communicated with the water filling port 71, and the other end of the first connection pipe has a first water inlet joint 20a. One end of the second communication pipe 92 is communicated with the heating port, and the other end of the second communication pipe 92 has a first liquid supply joint 20c. Among them, the water filling port 71, the liquid adding port 72 and the water pumping port 73 are all located at the top of the water storage tank 7, so that the liquid in the water storage tank 7 can be prevented from blocking the water filling port 71 and the heating port, and the resistance of clean water and cleaning liquid entering the water storage tank 7 can be reduced.

[0084] According to some embodiments of the present utility model, a cleaning tank is formed in the cleaning base station 20. A sewage inlet 82 communicated with the cleaning tank is formed on the sewage tank 8. The sewage inlet 82 is located at the top of the sewage tank 8, so that the sewage in the sewage tank 8 can be prevented from blocking the sewage inlet 82, and further the resistance of the sewage in the cleaning tank entering the sewage tank 8 can be reduced.

[0085] According to some embodiments of the present utility model, the cleaning base station 20 further includes an air extraction unit. An air extraction port 83 is further formed on the sewage tank 8, and the air inlet of the air extraction unit is communicated with the air extraction port 83. That is to say, the air extraction pump can discharge the gas in the sewage tank 8 through the air extraction port 83 to reduce the air pressure value in the sewage tank 8, so as to form a pressure difference between the cleaning tank and the sewage tank 8. The sewage in the cleaning tank can enter the sewage tank 8 under the action of the pressure difference. Among them, the air extraction port 83 is located at the top of the sewage tank 8, which can prevent the sewage in the sewage tank 8 from blocking the air extraction port 83, so as to ensure that the air extraction pump can smoothly extract the gas in the sewage tank 8 through the air extraction port 83 to form a negative pressure state.

[0086] According to some embodiments of the present utility model, the water storage tank 7 and the sewage tank 8 are arranged along the second direction e2. A mating cavity 61 that opens forward is formed at the lower part of the machine shell 6. The cleaning device 200 is detachably mated with the mating cavity 61. A functional component 62 is provided above the mating cavity 61. Among them, the functional component 62 can be a dust collection module, a disinfection module, etc., which are not specifically limited here. The functional component 62 is located below the water storage tank 7 and the sewage tank 8.

[0087] Next, the cleaning system 1000 according to the third aspect embodiment of the present utility model will be described with reference to the accompanying drawings.

[0088] The cleaning system 1000 according to the third aspect embodiment of the present utility model includes: a base station assembly 100 and a cleaning device 200. The cleaning device 200 is detachably mated with the cleaning base station 20. Among them, the cleaning device 200 is movable and has a mopping member. The cleaning device 200 can mop the ground through the mopping member. When the mopping member is contaminated with more dirt, it can move to the cleaning base station 20 for cleaning to restore the cleanliness of the mopping member, so as to ensure the cleaning effect and efficiency of the cleaning device 200.

[0089] For the cleaning system 1000 according to the third aspect embodiment of the present utility model, the user can install the water supply and drainage module 10 on the cleaning base station 20 according to the usage requirements to add an automatic water supply and drainage function to the cleaning base station 20, so as to save the cost of the user purchasing an additional cleaning base station 20 with an automatic water supply and drainage function, and further reduce the transformation cost of the cleaning base station 20. In addition, the water supply and drainage module 10 is located outside the cleaning base station 20, with low installation difficulty and convenient for later maintenance.
