[0038] To explain the technical solutions provided in the present application, the following detailed description is given with reference to specific drawings and examples.

[0039] In one embodiment (ie, embodiment 1) of the present application, referring to FIGS. 1-17, a water exchange station 30 is provided for automatically connecting with a smart vacuum cleaner 40 .

[0040] 1, 9 and 16, the water exchange base 30 includes a main body 300, a wastewater exchange port 101, a fresh water exchange port 102, a first wastewater connection port 201, a first fresh water connection port 202, and a water supply valve for controlling fresh water to enter the water exchange base 30 or the smart vacuum cleaner 40. The wastewater exchange port 101 is used to abut the wastewater inlet 45 of the smart vacuum cleaner 40, and the fresh water exchange port 102 is used to abut the fresh water inlet 44 of the smart vacuum cleaner 40. In some embodiments, the main body 300 may be generally rectangular. The smart vacuum cleaner 40 may have an integrated vacuuming and floor mopping function, a single floor mopping function, or a single cleaning function.

[0041] 1 and 9, the first fresh water connection port 202 is used to connect to an external water source. Specifically, the first fresh water connection port 202 is connected to a fresh water pipe connection port of a faucet or a faucet converter via a water pipe (not shown), and fresh water is sent to the first fresh water connection port 202 via the faucet. Here, the first fresh water connection port 202 can be connected to the fresh water exchange port 102 via a water pipe or other device, and is not limited thereto.

[0042] 1 and 9, the first sewage connection port 201 is connected to the sewage exchange port 101 and is used to discharge sewage to the outside. Specifically, the first sewage connection port 201 is connected to a pool, a toilet, a drain, or the like via a water pipe (not shown). Here, the first sewage connection port 201 can be connected to the sewage exchange port 101 via a water pipe or other device, and is not limited thereto.

[0043] In the present application, communication may be direct communication with each other, indirect communication, or communication controlled by a valve or a pump, etc., and communication may be constant communication or communication in a certain state (water supply state or water intake state), and it should be understood that this is not limited thereto.

[0044] Referring to Figures 1, 9 and 16, when the fresh water port 44 of the smart vacuum cleaner 40 abuts against the fresh water exchange port 102 of the water exchange base 30 and is in a fresh water supply state, the first fresh water connection port 202 is connected to the fresh water exchange port 102, and fresh water from the faucet is supplied to the inside of the smart vacuum cleaner 40 through the first fresh water connection port 202 and the fresh water exchange port 102, eliminating the need for the smart vacuum cleaner 40 and the water exchange base 30 to manually refill water, making it easier to use and greatly improving the user experience.

[0045] 1, 9 and 16, when the sewage outlet 45 of the smart vacuum cleaner 40 is in contact with the sewage exchange port 101 of the water exchange base 30 and in the sewage discharge state, the sewage inside the smart vacuum cleaner 40 is taken out through the sewage exchange port 101 and discharged to the outside through the first sewage connection port 201, eliminating the need to manually treat or clean the sewage inside the smart vacuum cleaner 40 and the water exchange base 30, which is convenient to use and greatly improves the user experience. In addition, the sewage inside the water exchange base 30 can be quickly discharged and cleaned, and bacteria and unpleasant odors are less likely to form inside the water exchange base 30.

[0046] 1, 10, 11 and 16, in another embodiment of the present application, the main body 300 is provided with a pump 230, which may be provided inside or outside the main body 300. When the wastewater outlet 45 of the smart vacuum cleaner 40 abuts against the wastewater exchange port 101 and is in a wastewater discharge state, the pump 230 provides power to extract wastewater from the smart vacuum cleaner 40 through the wastewater exchange port 101 and discharge the wastewater to the outside through the first wastewater connection port 201, thereby realizing automatic wastewater discharge. Here, the pump 230 may be a pump structure such as a self-priming pump or a diaphragm pump.

[0047] In another embodiment, there is no pump in the water exchange base 30. In this case, after the smart vacuum cleaner 40 comes into contact with the water exchange base 30, the height difference is used to automatically discharge the dirty water in the smart vacuum cleaner 40 into the water exchange base 30, and the water exchange base 30 removes the dirty water from the smart vacuum cleaner 40.

[0048] 1, 11, 13, 14 and 16, the main body 300 is provided with a sewage treatment device 220, and a sewage inlet 220a and a sewage outlet 220b are provided on the outer wall of the sewage treatment device 220, which are connected to the interior of the sewage treatment device 220.

The sewage treatment device 220 is connected to a pump 230, and in a sewage discharge state, the pump 230 extracts sewage from the smart vacuum cleaner 40 into the sewage treatment device 220. Specifically, when the sewage outlet 45 of the smart vacuum cleaner 40 abuts against the sewage exchange port 101 of the water exchange base 30 and is in a sewage discharge state, the pump 230 operates, and the sewage in the smart vacuum cleaner 40 flows into the sewage treatment device 220 through the sewage exchange port 101 and the sewage inlet 220a, and then the sewage in the sewage treatment device 220 is discharged to places such as a pool, toilet or floor drain through the sewage outlet 220b, the sewage discharge pipe 222 and the first sewage connection port 201, thereby realizing automatic discharge of sewage.

[0049] Furthermore, there is no need to manually treat the wastewater in the wastewater treatment device 220, making it convenient to use. The wastewater in the wastewater treatment device 220 can be discharged and cleaned in a timely manner, making it less likely for bacteria and unpleasant odors to form in the wastewater treatment device 220, greatly improving the user experience.

[0050] In a specific embodiment, referring to FIG. 10, the pump 230 is connected to the wastewater discharge pipe 222 , and of course, the pump 230 may be connected between the wastewater inlet 220 a and the wastewater exchange port 101 .

[0051] 1, 10, 13, 15, and 16, the wastewater treatment device 220 is provided with an upper storage chamber 223 and a lower storage chamber 224 that communicate with each other, and the lower storage chamber 224 is in contact with the wastewater inlet 220a so that wastewater is introduced from the wastewater inlet 220a into the lower storage chamber 224. The upper storage chamber 223 is in contact with the wastewater outlet 220b so that the wastewater filtered in the upper storage chamber 223 is discharged from the wastewater outlet 220b. A filter assembly 240 is provided between the upper storage chamber 223 and the lower storage chamber 224. The pump 230 extracts wastewater from the smart vacuum cleaner 40, causes the wastewater to flow through the wastewater inlet 220a, passes through the lower storage chamber 224, the filter assembly 240, and the upper storage chamber 223 in this order, and filters the wastewater through the filter assembly 240. The filtered wastewater is then discharged from the wastewater outlet 220b, the wastewater discharge pipe 222, and the first wastewater connection port 201 to a pool, toilet, floor drain, or other location. Specifically, the filter assembly 240 can filter out impurities such as large dust particles and large sludge in the wastewater, and the filtered wastewater passes through the pump 230 without clogging or damaging the pump 230. Furthermore, after the wastewater is filtered by the filter assembly 240 in the wastewater treatment device 220, the wastewater is discharged by a single pump 230 (a pump 230 for extracting wastewater from the smart vacuum cleaner, which is a self-priming pump), eliminating the need to simultaneously install a vacuum pump for extracting wastewater from the smart vacuum cleaner 40 to the water exchange base 30, an impeller pump for discharging wastewater from the water exchange base 30, and a wastewater tank for storing wastewater, which saves costs, reduces the volume of the water exchange base 30, and simplifies the installation of the water exchange base 30.

[0102] Specifically, referring to Figures 3, 6 and 16, when the sewage outlet 45 and fresh water outlet 44 of the smart vacuum cleaner 40 abut against the sewage exchange outlet 101 and fresh water exchange outlet 102 respectively, an impact force acts on the sewage exchange outlet 101 and fresh water exchange outlet 102, and the elastic plate 130 is elastically deformed, so that the fresh water exchange outlet 102 and the sewage exchange outlet 101 can elastically float through the elastic plate 130 and finely adjust their own position, so that the fresh water exchange outlet 102 and the sewage exchange outlet 101 can not only accurately abut against the fresh water outlet 44 and the sewage outlet 45 of the smart vacuum cleaner 40, but also can cushion the impact force caused by the movement of the smart vacuum cleaner 40.

[0103] Furthermore, the elastic plate 130 may be made of elastic plastic or other elastic material, and an elastic member (for example, a spring) may be connected to the elastic plate 130 so that the elastic plate 130 can move elastically.

A fixing member 135 presses the mounting ring 131 to be fixedly connected to the base housing 100, thereby fixing the elastic plate 130 to the first mounting hole 105 and providing a strong attachment. The fixing member 135 may be fixed to the inner wall of the base housing 100 by engagement, adhesion, screwing, or other methods.

[0105] In a specific embodiment, referring to Figures 5 and 7, the fixing member 135 has a plurality of first connecting holes 136 extending therethrough, and a plurality of first screw posts 105a are provided on the inner wall of the base housing 100, and the threaded rods of each first screw (not shown) pass through the first connecting holes 136 and are screwed into the threaded holes of the first screw posts 105a, thereby fixing the fixing member 135 to the inner wall of the base housing 100, and the structure is simple.

[0106] Furthermore, referring to Figures 6 and 7, the mounting ring 131 is provided with an annular groove 132, and the inner wall of the base housing 100 is provided with an annular protrusion 106 around the first mounting port 105. The annular protrusion 106 engages with the annular groove 132, thereby firmly fixing the elastic plate 130 to the inner wall of the base housing 100 and stabilizing the structure.

[0107] Preferably, referring to FIGS. 6 and 7, the cross section of the elastic plate 130 is wavy so that the elastic plate 130 has good elasticity.

[0108] 6 and 7, the support frame 140 includes a first support plate 141 and a second support plate 142. The first support plate 141 and the second support plate 142 are respectively fixed to opposite sides of the elastic plate 130, and the wastewater exchange port 101 and the fresh water exchange port 102 are provided on the first support plate 141. Specifically, the first support plate 141 and the second support plate 142 may be fixed to opposite sides of the elastic plate 130 by means of engagement, adhesion, or screwing. Here, referring to FIGS. 13 and 14, the wastewater exchange port 101 and the fresh water exchange port 102 may be integral with the first support plate 141, or may be separate structures provided that the structure is strong, and are not limited thereto.

[0109] 6 and 7, a mounting hole 133 is formed through the center of the elastic plate 130, and the first support plate 141 and the second support plate 142 press against the peripheral edges on both sides of the mounting hole 133, respectively, and the first support plate 141 and the second support plate 142 are fixed by means of engagement, adhesion, screwing, or the like, so that the first support plate 141 and the second support plate 142 are firmly connected to opposite sides of the elastic plate 130.

[0110] In a specific embodiment, referring to Figures 6 and 7, the second support plate 142 is provided with a plurality of second connecting holes 143 penetrating therethrough, and the first support plate 141 is provided with a plurality of second screw posts 144, and the threaded rods of each second screw pass through the second connecting holes 143 and are screwed into the threaded holes of the second screw posts 144 to fasten the first support plate 141 and the second support plate 142 together, resulting in a simple structure.

Specifically, when the sewage inlet 45 and the fresh water inlet 44 of the smart vacuum cleaner 40 move to abut against the sewage exchange port 101 and the fresh water exchange port 102 respectively, the first support plate 141 moves toward the inside of the base housing 100, the elastic plate 130 elastically deforms toward the inside of the base housing 100, and the first support plate 141 does not move until it abuts against the limiting structure 137, preventing the first support plate 141 from moving too far, thereby preventing the fresh water exchange port 102 and the sewage exchange port 101 from moving too far, and ensuring that the fresh water exchange port 102 and the sewage exchange port 101 abut accurately against the fresh water inlet 44 and the sewage inlet 45 of the smart vacuum cleaner 40. When the smart vacuum cleaner 40 moves and disengages from the contact between the dirty water exchange port 101 and the purified water exchange port 102, the first support plate 141 moves to the outside of the base housing 100, the elastic plate 130 elastically deforms to the outside of the base housing 100, and the second support plate 142 does not move until it contacts the position limiting structure 137, thereby avoiding the second support plate 142 from moving too much and ensuring that the elastic plate 130 elastically deforms within an appropriate range.

[0112] Furthermore, referring to Figures 3 and 16, a first elastic sealing material 107 is fitted into one end of each of the sewage exchange port 101 and the fresh water exchange port 102 extending outside the base housing 100, thereby sealingly connecting the sewage exchange port 101 to the sewage port 45 of the smart vacuum cleaner 40, and sealingly connecting the fresh water exchange port 102 to the fresh water port 44 of the smart vacuum cleaner 40, thereby performing a sealing function and preventing leakage of fresh water or sewage water.

[0113] In another embodiment, referring to Figures 3, 7 and 16, a first elastic seal member 107 is also fitted to one end of the graywater inlet 170 extending outside the base housing 100, sealingly connecting the graywater inlet 170 to the graywater port 46 of the smart vacuum cleaner 40 and preventing the graywater from leaking to the outside.

[0114] 3 and 16, in another embodiment of the present application, the contact structure further includes a contact head 160.

Specifically, the smart vacuum cleaner 40 is provided with a corresponding alignment groove, and the contact head 160 is properly inserted into the alignment groove of the smart vacuum cleaner 40 to position and contact the smart vacuum cleaner 40, thereby accurately contacting the fresh water exchange port 102 and the waste water exchange port 101 with the fresh water inlet 44 and the waste water inlet 45 of the smart vacuum cleaner 40, or accurately contacting the charging part 47 and the charging connector 150 of the smart vacuum cleaner 40, thereby preventing misalignment and ensuring a reliable structure.

[0115] Preferably, referring to Figures 3 and 16, the contact head 160 is mounted on the first support plate 141 and positioned beside the dirty water exchange port 101 and the fresh water exchange port 102 so as to be positioned and abutted against the smart vacuum cleaner 40.

In this embodiment, the control circuit board 151 can be configured using a PLC or an integrated chip according to actual production needs. Since the control circuit board 151 is a technically established and mature technology in the prior art, those skilled in the art should be familiar with and understand how the control circuit board 151 controls the operation of the water exchange base 10, and therefore the control principle thereof will not be described herein.

[0117] In another embodiment of the present application (i.e., embodiment 2), referring to Figures 18-20, the water exchange station 30 preferably includes an accumulation mechanism including an accumulation housing 300a, a wastewater treatment device 220 provided in the accumulation housing 300a, a wastewater input / output control device 900, and a water supply valve (e.g., a three-way valve 310).

[0118] 18-20, the water supply valve can be connected to the sewage treatment device 220 and used to control the input of fresh water to flush the sewage treatment device 220, and / or the water supply valve can be connected to the first fresh water tank 210 of the water exchange station 30 and used to control the input of fresh water to replenish the first fresh water tank 210 of the water exchange station 30 with fresh water.

[0119] 20-27, the sewage inlet / outlet control device 900 is connected to the sewage treatment device 220 and controls the sewage to enter the sewage treatment device 220, and / or controls the sewage to be discharged outside the sewage treatment device 220 after flushing the sewage treatment device 220.

[0120] Compared with the prior art, the one or more technical solutions used in the integrated mechanism of the water exchange station 30 according to the embodiment of the present application have at least one of the following technical advantages:

[0121] 18-21, the sewage treatment device 220, the sewage inlet / outlet control device 900, and the water supply valve are integrated into an integrated housing 300a to form an integrated mechanism, which makes the overall structure of the integrated mechanism compact and easy to install. By applying this integrated mechanism to the water exchange station 30, the water exchange station 30 occupies less space and its volume can be reduced, making it easier to use.

[0122] 22, 23, and 25, in another embodiment of the present application, the sewage inlet / outlet control device 900 includes a first connection port 940, a second connection port 950, a valve body, and a third connection port 960. The third connection port 960 is connected to the sewage treatment device 220. The valve body controls the introduction of sewage into the sewage treatment device 220 through the first connection port 940 and the third connection port 960, and / or controls the sequential discharge of sewage after flushing the sewage treatment device 220 through the third connection port 960 and the second connection port 950. Here, the third connection port 960 may be two independent connection ports or a single connection port, and may be determined according to actual usage conditions. The sewage inlet / outlet control device 900 may be a single structural device, or a combination of multiple structural devices to control the introduction of sewage into the sewage treatment device 220 and / or the discharge of sewage after flushing the sewage treatment device 220.

[0123] Referring to FIG. 19, the first connection port 940 is connected to external sewage (e.g., sewage inside the smart vacuum cleaner) for inputting sewage. As can be understood, the first connection port 940 is connected to the sewage connection port (e.g., including the sewage exchange port 101) of the water exchange base 30 via a water pipe, and by abutting against the smart vacuum cleaner via the sewage connection port, the sewage inside the smart vacuum cleaner can be input from the first connection port 940.

[0124] 22, 23, and 25, the sewage inlet / outlet control device 900 further includes a control housing 9100. The valve body includes a first valve body 910 and a second valve body 920. A sewage passage 930 is provided within the control housing 9100. A first connection port 940, a second connection port 950, and a third connection port 960 are provided on the outer wall of the control housing 9100 and all communicate with the sewage passage 930. The first valve body 910 is provided at the first connection port 940 and controls sewage so that it is sequentially introduced into the sewage treatment device 220 from the first connection port 940, the sewage passage 930, and the third connection port 960. The second valve body 920 is provided at the second connection port 950 and controls sewage so that after rinsing the sewage treatment device 220, it is sequentially discharged to the outside from the third connection port 960, the sewage passage 930, and the second connection port 950. As can be understood, the second connection port 950 is connected to the wastewater connection port of the water exchange station 30 via a water pipe, and then the wastewater can be discharged through the wastewater connection port to a pool, toilet, floor drain, etc., thereby making the structure simple.

When wastewater enters the wastewater passage 930 through the first connection port 940 and enters the wastewater treatment device 220 through the third connection port 960, the wastewater can enter the wastewater passage 930 from the first connection port 940 through the first check valve, but the wastewater in the wastewater passage 930 cannot be discharged from the second connection port 950 through the second check valve. 23 and 25, when fresh water is delivered to flush the sewage treatment device 220, the sewage after cleaning the sewage treatment device 220 enters the sewage passage 930 through the third connection port 960. At this time, the sewage in the sewage passage 930 is discharged from the second connection port 950 through the second check valve, but cannot be discharged from the first connection port 940 through the first check valve. The use of the first and second check valves simplifies the structure and does not require electrical control. Here, either the first check valve or the second check valve controls the water flow to flow in or out in a specific direction.

[0126] 23 and 25, the wastewater passage 930 includes a first passage section 931 and a second passage section 932.

Both ends of the second passage section 932 are connected to a third connection port 960 and a second connection port 950, respectively, so that wastewater after rinsing the wastewater treatment device 220 is introduced into the second passage section 932 from the third connection port 960 and then discharged from the second connection port 950 via the second valve body 920, resulting in a simple structure.

[0127] In a specific embodiment, referring to FIG. 23, the first passage section 931 and the second passage section 932 are connected, and the first passage section 931 and the second passage section 932 include a common passage 933, and a part of the first passage section 931 and the second passage section 932 adopts a common passage structural method, which can reduce the overall volume of the sewage inlet and outlet control device 900, has a compact structure, and is easy to process.

[0128] 22 and 24, the control housing 9100 includes a first housing 901 and a second housing 902. The first housing 901 and the second housing 902 are appropriately joined together, and a wastewater passage 930 is formed therebetween. By forming the control housing 9100 as a combination of the first housing 901 and the second housing 902, it becomes easy to process the wastewater passage 930 and to attach the first valve body 910 and the second valve body 920. Here, the first housing 901 and the second housing 902 may be fixed to each other by means of engagement, adhesion, screwing, or the like.

[0129] Furthermore, as shown in FIG. 24, a plurality of positioning posts 903 and positioning holes 904 that can be engaged and inserted are provided between the first housing 901 and the second housing 902, and the engagement and insertion of the positioning posts 903 and the positioning holes 904 allows the first housing 901 and the second housing 902 to be assembled accurately and easily.

In other embodiments, the control housing 9100 may be attached to the integrated housing 300a in other ways, such as by screwing.

[0131] 27, in another embodiment of the present application, a filter assembly 240 is provided in the wastewater treatment device 220. Referring to FIGS. 25 to 27, a wastewater inlet 220a communicating with the interior of the wastewater treatment device 220 is provided on the outside of the wastewater treatment device 220, and the wastewater inlet 220a is connected to a third connection port 960 of the wastewater input / output control device 900. External wastewater is input into the wastewater passage 930 of the wastewater input / output control device 900 from the first connection port 940 and then input into the wastewater treatment device 220 via the third connection port 960 and the wastewater inlet 220a. The filter assembly 240 is used to filter the wastewater input into the wastewater treatment device 220, and the filter assembly 240 can filter out impurities such as large dust particles and large sludge in the wastewater.

[0132] 25-27, fresh water from outside enters the sewage treatment device 220 to clean the filter assembly 240, washing away impurities such as large dust and sludge adhering to the filter assembly 240. The cleaned sewage passes through the sewage inlet 220a and the third connection port 960, and is discharged outside through the second connection port 950 via the sewage passage 930 of the sewage input / output control device 900.

[0133] Preferably, referring to Figures 20 and 25, the sewage input / output control device 900 is installed next to the sewage inlet 220a of the sewage treatment device 220, which makes it convenient to connect the third connection port 960 to the sewage inlet 220a and has a compact structure.

[0134] 24, 25, and 27, in a specific embodiment, the wastewater treatment device 220 includes an upper storage chamber 223 and a lower storage chamber 224 that communicate with each other, and a filter assembly 240 is disposed between the upper storage chamber 223 and the lower storage chamber 224 to separate the upper storage chamber 223 and the lower storage chamber 224. The lower storage chamber 224 communicates with the wastewater inlet 220a, and external wastewater passes through the first connection port 940, the wastewater passage 930, the third connection port 960, and the wastewater inlet 220a to enter the lower storage chamber 224, and then passes through the filter assembly 240 to enter the upper storage chamber 223, whereby the wastewater is filtered by the filter assembly 240. The wastewater flows from bottom to top for filtration, which allows subsequent filtered wastewater to flow directly out by gravity and facilitates subsequent flushing of the filter assembly 240.

[0135] 20, 25, and 27, a flushing connection port 220c communicating with the upper storage chamber 223 is provided on the outer wall of the sewage treatment device 220. The flushing connection port 220c is connected to a water supply valve. The inlet end of the water supply valve can be connected to an external water source (e.g., a faucet) to supply fresh water via the external water source (e.g., a faucet). The flushing connection port 220c is used to introduce fresh water into the sewage treatment device 220 to wash the filter assembly 240. Impurities such as large dust and sludge washed out of the filter assembly 240 fall into the lower storage chamber 224 and are then discharged to the outside via the sewage inlet 220a, the third connection port 960, the sewage passage 930, and the sewage outlet 150, thereby cleaning impurities such as large dust and sludge adhering to the filter assembly 240. This allows the filter assembly 240 to be used for a long period of time, eliminating or reducing the need for manual cleaning.

[0136] 20 and 21, the water supply valve is preferably installed beside the flush connection port 220c of the sewage treatment device 220, which makes it easy to connect the water supply valve to the flush connection port 220c and has a compact structure. Specifically, the water supply valve may be attached to the integrated housing 300a by a method such as threading or engagement.

[0137] 19, 25, and 27, the sewage treatment device 220 is connected to a pump 230. The pump 230 extracts external sewage and passes the sewage from the first connection port 940 through the sewage passage 930 of the sewage input / output control device 900, the third connection port 960, the sewage inlet 220a, the lower storage chamber 224, the filter assembly 240, and the upper storage chamber 223 in that order, so that the sewage flows from bottom to top and is filtered by the filter assembly 240. A sewage outlet 220b communicating with the upper storage chamber 223 is provided on the outer wall of the sewage treatment device 220, and the sewage outlet 220b discharges the sewage filtered by the filter assembly 240 in the upper storage chamber 223. As can be understood, the sewage outlet 220b is connected to a sewage connection port of the water exchange station 500, and the sewage connection port can discharge the sewage to a pool, a toilet, a floor drain, or other locations to discharge the sewage. The filter assembly 240 can filter out impurities such as large dust particles and large sludge in the wastewater, and the filtered wastewater will not clog or damage the pump 230 when it passes through the pump 230 .

[0138] 26 and 27, in an embodiment of the present application, the filtration assembly 240 includes a filtration layer 244 through which water can flow, and a support structure 241 provided within the filtration layer 244.

A plurality of first through grooves 242 are provided at the bottom of the support structure 241, and a filtration layer 244 covers the plurality of first through grooves 242. The first through grooves 242 allow wastewater to be transported into the support structure 241 after being filtered by the filtration layer 244. A plurality of second through grooves 243 are provided at the top of the support structure 241, and the second through grooves 243 allow filtered wastewater to be discharged from the support structure 241 to the wastewater outlet 220b of the wastewater treatment device 220. The wastewater is only discharged from the wastewater outlet 220b after being filtered by the filtration layer 244, providing a sufficient filtration effect. When rinsing the filter layer 244, fresh water enters the upper storage chamber 223 through the flushing connection port 220c, passes through the second through-groove 243 into the support structure 241, and then passes through the first through-grooves 242 to be sprayed onto the filter layer 244, washing away large dust particles and sludge adhering to the filter layer 244, thereby achieving a good washing effect. Referring to Figures 24, 25, and 27, the washed-out impurities such as large dust particles and sludge fall into the lower storage chamber 224, and finally the wastewater passes through the wastewater inlet 220a, the third connection port 960, and the wastewater passage 930 before being discharged from the second connection port 950.

[0139] Here, the filter layer 244 may be filter cotton, filter mesh, filter cloth, etc., and is not limited thereto.

The user rotates the tank lid 227 forward to lock the plurality of locking protrusions 227a into the plurality of locking grooves 226a one by one, thereby placing the tank lid 227 on the tank port 226, and then rotates the tank lid 227 backward to disengage the locking protrusions 227a from the locking grooves 226a, thereby removing the tank lid 227 from the tank port 226. This has a simple structure and is easy to operate.

[0144] Furthermore, referring to Figures 26 and 27, a rotating part 227b is provided on the top of the tank lid 227, which makes it convenient for the user to twist the tank lid 227 and is easy to operate.

Specifically, a corresponding alignment groove is provided on the smart vacuum cleaner (not shown), and the contact bed 160 is properly inserted into the alignment groove of the smart vacuum cleaner to position and contact the smart vacuum cleaner. By using the contact bed 160 to position (limit) the smart vacuum cleaner, the water exchange base 30 does not cover the majority of the smart vacuum cleaner, and the volume of the water exchange base 30 can be reduced.

[0159] 18 and 19, the surface of the main body 300 located on the side of the dirty water exchange port 101 (dirty water inlet) or the fresh water exchange port 102 (fresh water outlet) is recessed with a contact surface 530, which is an arc-shaped surface that fits the outer arc-shaped surface of the smart vacuum cleaner. In other embodiments, the contact surface 530 may be a flat surface.

[0160] In another embodiment of the present application, referring to Figures 18 and 19, the outer wall of the first fresh water tank 210 is provided with a fresh water inlet 212 and a fresh water outlet 211 that are connected to the inside thereof, and the second water outlet 313 of the water supply valve (e.g., a three-way valve 310) is connected to the fresh water inlet 212 and controls fresh water to be introduced through the fresh water inlet 212 so as to replenish fresh water into the first fresh water tank 210, and the fresh water outlet 211 is connected to the fresh water exchange port 102 (fresh water outlet), and when the fresh water exchange port 102 abuts against the smart vacuum cleaner, the fresh water in the first fresh water tank 210 is replenished to the smart vacuum cleaner through the fresh water exchange port 102.

The third nozzle 443 of the three-way pipe 440 communicates with the fresh water exchange port 102 (fresh water outlet), and fresh water is replenished to the smart vacuum cleaner through the fresh water exchange port 102.

[0162] 21, 28, and 30, the first fresh water tank 210 is provided with a quick connector 410 for convenient connection to a water pipe. For example, the quick connector 410 may be quickly connected to the second water outlet 313 of the water supply valve in the water exchange station 30 via a water pipe, or the quick connector 410 may be quickly connected to an external water source (e.g., a faucet) via a water pipe. Referring to FIGS. 28 and 30, a first end of the quick connector 410 is a fresh water inlet 212, and a second end of the quick connector 410 is provided with a water supply passage 411.

[0163] 28-30, a water volume control device 430a is provided in the first fresh water tank 210, and one end of the water volume control device 430a is movably connected to the water supply passage 411. When the fresh water in the first fresh water tank 210 reaches a predetermined level (the predetermined level is determined based on the internal capacity of the water tank at or near the full water position of the water tank), the water volume control device 430a blocks the water supply passage 411 to prevent fresh water from entering the first fresh water tank 210, thereby preventing the water in the first fresh water tank 210 from becoming too full and overflowing, and the structure is reliable.

[0164] 19 and 29, the first fresh water tank 210 is provided with an overflow port 215 communicating with its interior. The overflow port 215 discharges excess fresh water from the first fresh water tank 210, preventing leakage due to excessive fresh water in the first fresh water tank 210. Specifically, the overflow port 215 can discharge overflowed fresh water via a water pipe to a pool, toilet, floor drain, or other location, resulting in a simple structure. In a specific embodiment, the overflow port 215 is connected to the third water connection port 333 of the manifold 330 via a water pipe, and excess fresh water from the first fresh water tank 210 flows into the manifold 330 and is discharged to the outside via the drain connection port 334.

[0168] 32 and 33, at least a portion of the water level detection element 800 is disposed in the water collection channel 121 and is electrically connected to the first control module 700. When the water level in the water collection channel 121 rises up to the water level detection element 800, the water level detection element 800 detects a leak and sends an electrical signal back to the first control module 700 to control the water exchange station 30 to stop the corresponding operation, which may include all or some of the water exchange operations, thereby informing the user that a leak has occurred in the water exchange station and requiring timely inspection of the water exchange station. This prevents the risk of electric shock if the leak is not detected in a timely manner and ensures high safety.

Water leaking from inside the main body 300 flows into the bottom cover 360 through the guiding port 111 and is collected in the water collection groove 121. The provision of the water collection groove 121 on the bottom cover 360 makes it easy to remove the bottom cover 360, allowing for easy disposal of water in the water collection groove 121 after inspection or troubleshooting.

[0170] Preferably, referring to FIG. 36, the bottom wall of the case 350 is provided with a plurality of guiding ports 111, which improve the efficiency of the leakage water flowing into the water collecting groove 121 of the bottom cover 360.

[0171] 33 and 36, the bottom wall of the case 350 is provided with a first inclined surface 112 that slopes from its edge toward the inlet 111. Water leaking from inside the main body 300 falls onto the bottom wall of the case 350, and the first inclined surface 112 guides the leaking water toward the inlet 111, where it is quickly collected and flows from the inlet 111 into the water collection groove 121 of the bottom cover 360. The first inclined surface 112 serves to merge the water and prevent it from accumulating on the top surface of the bottom wall of the case 350.

[0172] Referring to Figure 35, one side of the bottom wall of the case 350 protrudes to form a step 113, and a bottom cover 360 is installed in a notch 114 on one side of the step 113, which makes efficient use of the space in the case 350 and the bottom of the bottom cover 360 is flush with the bottom of the case 350, facilitating stable placement of the main body 300.

[0176] 32 and 36, in another embodiment of the present application, the water level detection member 800 includes a positive probe 810 and a negative probe 820 electrically connected to the first control module 700. The positive probe 810 and the negative probe 820 are symmetrically spaced apart, and at least a portion of the lower ends of the positive probe 810 and the negative probe 820 are inserted into the water collection tank 121. When the water level in the water collection tank 121 increases until it contacts the lower ends of the positive probe 810 and the negative probe 820, the positive probe 810 and the negative probe 820 are electrically connected to each other using water as a conductive medium to form a circuit, and an electrical signal is fed back to the first control module 700 to control the water exchange station to stop the corresponding operation, thereby realizing water leakage detection.

[0177] 32 and 34, the upper ends of the positive probe 810 and the negative probe 820 are both bent to form mounting portions 830, and the mounting portions 830 are fixed to the bottom of the case 350 of the main body 300. Specifically, two through holes 116 are symmetrically formed in the bottom of the case 350, and the upper ends of the positive probe 810 and the negative probe 820 respectively pass through the two through holes 116, and the mounting portions 830 are fixed to the bottom of the case 350 by means of engagement, adhesion, screws, or the like.

[0179] S11: Based on the first detection module, detect whether the water exchange base 30 and the smart vacuum cleaner 40 are in sufficient contact with each other.

[0180] Referring to Figures 3 and 16, the above-mentioned "sufficient abutment" refers to the fact that when the smart vacuum cleaner 40 enters the water exchange state, it moves to the water exchange base 30 according to the guidance of the map or the position detection sensor, and fully abuts the wastewater exchange port 101 of the water exchange base 30 with the wastewater port 45 of the smart vacuum cleaner 40, and / or fully abuts the fresh water exchange port 102 of the water exchange base 30 with the fresh water port 44 of the smart vacuum cleaner 40, and / or fully abuts the charging connector 150 of the water exchange base 30 with the charging unit 47 of the smart vacuum cleaner 40.

[0181] S12: Based on the second control module installed in the water exchange base 30, water is supplied to the fresh water outlet 44 of the smart vacuum cleaner 40 through the fresh water exchange port 102 of the water exchange base 30, and / or water is collected from the waste water outlet 45 of the smart vacuum cleaner 40 through the waste water exchange port 101 of the water exchange base 30.

[0182] Here, the first fresh water connection port 202 of the water exchange base 30 is connected to an external water source, and then fresh water is supplied to the fresh water port 44 of the smart vacuum cleaner 40 through the fresh water exchange port 102 of the water exchange base 30. The water exchange base 30 opens the water supply valve to control the fresh water to enter the water exchange base 30 or the smart vacuum cleaner 40. The whole process realizes the automatic input and output of water to the smart vacuum cleaner 40 by the water exchange base 30, which can improve the user experience.

[0183] The water exchange base 30 collects wastewater from the wastewater outlet 45 of the smart vacuum cleaner 40 through the wastewater exchange port 101, and then discharges the wastewater to the outside through the first wastewater connection port 201 of the water exchange base 30. The pump 230 of the water exchange base 30 extracts wastewater from the smart vacuum cleaner 40 through the wastewater exchange port 101. The whole process automatically discharges the wastewater of the smart vacuum cleaner 40 through the water exchange base 30, improving the user experience.

[0184] S13: Controlling the stopping of water supply and / or water collection based on the second control module at a predetermined time or based on the detection information from the smart vacuum cleaner 40.
