In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0033] 1 , a mobile water station 10 provided in one embodiment of the present application includes a first docking module 11 and a water tank 12 . The first docking module 11 is disposed on the water tank 12 , and is used to dock with a second docking module outside the mobile water station 10 .

[0034] It should be noted that there are multiple ways to set the first docking module 11. Optionally, the first docking module 11 is detachably mounted on the water tank 12. Optionally, the first docking module 11 is fixedly mounted on the water tank 12. Optionally, the first docking module 11 and the water tank 12 are integrally formed.

[0035] The second docking module can be arranged on the cleaning equipment, so that when the first docking module 11 and the second docking module are docked, the mobile water station 10 and the cleaning equipment can be directly connected successfully to realize the functions of adding clean water and discharging sewage. The second docking module can also be arranged on a fixed workstation, so that the mobile water station 10 and the fixed workstation form a workstation with the functions of independently completing the functions of adding clean water and discharging sewage, and there is no need to access the clean water source and the sewage discharge channel separately. After the cleaning equipment is successfully docked with the fixed workstation, the functions of adding clean water and discharging sewage to the cleaning equipment can be realized. The second docking module can also be arranged on other equipment, for example, a fixed base, and the base can realize the water and electricity connection with the cleaning equipment or the fixed workstation. In this way, after the mobile water station 10 is successfully docked with the base, it can be indirectly connected to the cleaning equipment through the base to realize the functions of adding clean water and discharging sewage to the cleaning equipment. Of course, the second docking module can also be arranged on other fixed or mobile equipment, which is not specifically limited here.

[0036] In one embodiment, referring to Figures 1 and 2, the first docking module 11 is provided with a first clean water connecting port 1111, a first sewage connecting port 1121 and a first conductive portion 113, and the first conductive portion 113 is used to dock with the second conductive portion on the second docking module to determine the docking state of the first docking module 11 and the second docking module.

[0037] Specifically, referring to FIG. 2 , the first docking module 11 is provided with a first mounting hole and a second mounting hole. A first clean water connector 111 is provided in the first mounting hole, and the first clean water connector 111 is provided with a first clean water communication port 1111.

The clean water chamber 1211 is in communication with the second clean water communication port 1213, and the sewage chamber 1212 is in communication with the second sewage communication port 1214. The first clean water communication port 1111 is in communication with the second clean water communication port 1213, and the first sewage communication port 1121 is in communication with the second sewage communication port 1214.

[0039] Specifically, the water tank 12 is provided with a third mounting hole, a second clean water connector is provided in the third mounting hole, and the second clean water connector is provided with a second clean water connecting port 1213. By providing the second clean water connector, it is convenient to connect with the first clean water connector 111.

As shown in FIG. 4, the second sewage connecting port 1214 is the same opening as the water inlet of the sewage chamber 1212, which simplifies the structural design of the sewage chamber 1212 and facilitates the sewage to enter the sewage chamber 1212.

[0040] When in use, the first docking module 11 is docked with the second docking module outside the mobile water station 10, and the first conductive part 113 is in contact with the second conductive part, so as to judge the docking state of the first docking module 11 and the second docking module. When the first docking module 11 and the second docking module are docked, the water in the clean water chamber 1211 can flow out through the second clean water connecting port 1213 and the first clean water connecting port 1111, and the mobile water station 10 realizes the function of adding clean water to the external cleaning equipment. The sewage outside the mobile water station 10 can also flow into the sewage chamber 1212 through the first sewage connecting port 1121 and the second sewage connecting port 1214, and the mobile water station 10 realizes the sewage receiving function. In this way, by setting the first docking module 11, it is convenient for the mobile water station 10 to dock with other equipment for water and electricity.

[0041] 2 and 7 , the first conductive portion 113 includes a first conductive contact 1131 , and the second conductive portion 23 includes a second conductive contact 231 . When the first docking module 11 and the second docking module 20 are docked, the first conductive contact 1131 and the second conductive contact 231 are in contact.

[0042] Of course, in other embodiments, the first conductive portion 113 and the second conductive portion 23 may also be other structures. For example, the first conductive portion 113 and the second conductive portion 23 are both conductive contacts, but the present invention is not limited thereto.

[0043] It should be noted that the number of the first conductive contacts 1131 and the second conductive contacts 231 can be set according to actual needs and is not specifically limited here.

[0044] Optionally, referring to Figures 2 and 7, there are two first conductive contacts 1131 and four second conductive contacts 231. When the first docking module 11 is docked with the second docking module 20, one of the first conductive contacts 1131 contacts with two of the second conductive contacts 231, and another first conductive contact 1131 contacts with the other two second conductive contacts 231.

[0045] In one embodiment, referring to FIG. 2 and FIG. 7 , the first docking module 11 is further provided with a first alignment portion 114, and the first alignment portion 114 is used to connect with the second alignment portion 24 on the second docking module 20. When the first docking module 11 is docked with the second docking module 20, the first alignment portion 114 is connected with the second alignment portion 24 to prevent the first docking module 11 from being separated from the second docking module 20, thereby ensuring the reliability of the docking between the first docking module 11 and the second docking module 20.

[0046] It should be noted that the number of the first alignment parts 114 and the second alignment parts 24 can be set according to actual needs.

[0047] Optionally, referring to FIG. 2 , two first alignment parts 114 are provided, and the two first alignment parts 114 are spaced apart along the length direction or width direction of the first docking module 11, and the first clean water communication port 1111, the first sewage communication port 1121 and the first conductive part 113 are all provided between the two first alignment parts 114. Two second alignment parts 24 are provided, and the two second alignment parts 24 are spaced apart along the length direction or width direction of the second docking module 20. Such an arrangement can ensure the reliability of docking between the first docking module 11 and the second docking module 20. Of course, in other embodiments, one, three or more first alignment parts 114 and the second alignment parts 24 can also be provided, and are not limited thereto.

[0048] Optionally, the docking method of the first alignment part 114 and the second alignment part 24 includes at least one of magnetic connection, clamping, plug-in and threaded connection. A magnetic attraction piece is provided on at least one of the first alignment part 114 and the second alignment part 24, and an adsorption piece is provided on the other. The magnetic attraction piece and the adsorption piece cooperate to achieve the docking of the first alignment part 114 and the second alignment part 24. Alternatively, the first alignment part 114 and the second alignment part 24 are connected by clamping, and a buckle part is provided on one of the first alignment part 114 and the second alignment part 24, and a clamping part is provided on the other, and the buckle part and the clamping part are engaged to achieve connection. Alternatively, the first alignment part 114 and the second alignment part 24 are connected by plugging, and a plug connector is provided on one of the first alignment part 114 and the second alignment part 24, and a plug slot is provided on the other, and the connection is achieved by plugging. Of course, the plug connector and the plug slot can be in an interference fit state, so as to strengthen the tightness of the connection between the first alignment part 114 and the second alignment part 24. Alternatively, the first alignment portion 114 and the second alignment portion 24 may be connected by threads, with a threaded hole being provided on one of the first alignment portion 114 and the second alignment portion 24, and a screw being provided on the other, so as to achieve a stable connection between the first alignment portion 114 and the second alignment portion 24. Of course, other connection methods may also be used, which will not be described in detail here.

[0049] In one embodiment, the first alignment portion 114 is provided with an alignment groove, and the second alignment portion 24 is provided with an alignment protrusion. Alternatively, referring to FIG. 2 and FIG. 7 , the first alignment portion 114 is provided with an alignment protrusion 1141, and the second alignment portion 24 is provided with an alignment groove 241. When the first docking module 11 is docked with the second docking module 20, the alignment protrusion 1141 is arranged in the alignment groove 241, and the groove wall of the alignment groove 241 plays a limiting role on the alignment protrusion 1141, which is conducive to improving the stability of the docking between the first docking module 11 and the second docking module 20.

[0050] Furthermore, the alignment protrusion 1141 is provided with a magnetic attraction member; and / or the bottom and / or the wall of the alignment groove 241 are provided with a magnetic attraction member. When the first docking module 11 is docked with the second docking module 20, the alignment protrusion 1141 and the alignment groove 241 are magnetically matched, further improving the docking stability of the first docking module 11 and the second docking module 20.

[0051] In one embodiment, referring to FIG. 3 and FIG. 5 , the mobile water station 10 further includes a liquid level sensor 13. The liquid level sensor 13 is mounted on the water tank 12, and the liquid level sensor 13 is used to detect the liquid level in the sewage chamber 1212. When in use, the liquid level sensor 13 detects the liquid level in the sewage chamber 1212 in real time, and if the liquid level in the sewage chamber 1212 exceeds a preset liquid level, the user is reminded to drain the water in the sewage chamber 1212 in time.

[0052] In one embodiment, referring to FIG. 4 , FIG. 5 and FIG. 9 , the liquid level sensor 13 is a float type liquid level sensor. Specifically, the liquid level sensor 13 includes a sensor plate 132 and a float switch 131. The sensor plate 132 is mounted on the water tank 12. The float switch 131 is disposed in the sewage chamber 1212, and the float switch 131 is electrically connected to the sensor plate 132. When the liquid level in the sewage chamber 1212 changes, the float of the float switch 131 will move accordingly, thereby driving the main body to move. At the same time, the magnet at the other end of the float will control the magnetic switch on the rod and send a signal to the sensor plate 132. The sensor plate 132 cooperates with the float switch 131 to detect the liquid level in the sewage chamber 1212. The float switch 131 is operated by magnetic force, has no mechanical connectors, is simple and reliable in operation, and has a long service life.

[0053] It should be noted that, referring to Figures 5 and 9, the float switch 131 and the sensor plate 132 cooperate to detect two states: the water tank is about to be full and the water tank is full. Specifically, the float switch 131 has an upper section and a lower section. When the lower section is triggered, it indicates that the water in the water tank 12 is about to be full. When both the upper section and the lower section are triggered, it indicates that the water in the water tank 12 is full.

[0054] Of course, in other embodiments, the liquid level sensor 13 may also be a capacitive liquid level sensor, but is not limited thereto.

[0055] In one embodiment, referring to FIG. 2 and FIG. 7, the mobile water station 10 further includes a control unit. When the first docking module 11 is docked with the second docking module 20, the control unit is electrically connected to the first conductive part 113 through the second conductive part 23. The control unit determines whether the first docking module 11 is docked with the second docking module 20 by obtaining the current value between the first conductive part 113 and the second conductive part 23. After the first conductive part 113 and the second conductive part 23 are connected, they are connected to the control unit. The control unit can collect the current between the first conductive part 113 and the second conductive part 23 to determine whether the docking between the first conductive part 113 and the second conductive part 23 is in place. It can be understood that when the first conductive part 113 and the second conductive part 23 are docked in place, the resistance between the two becomes smaller, and the current value after the connection becomes larger; if the first conductive part 113 and the second conductive part 23 are not docked in place, the resistance between the two is too large, and the current value after the connection is too small. In this way, by setting the current threshold, it can be determined whether the first conductive part 113 and the second conductive part 23 are docked in place.

[0056] In one embodiment, referring to FIG. 2 , FIG. 4 and FIG. 9 , the mobile water station 10 further includes a control unit 14 and a first water pump, and the first water pump is electrically connected to the control unit 14. The first water pump has a first water inlet and a first water outlet connected to the first water inlet, the first water inlet is connected to the clean water chamber 1211, and the first water outlet is connected to the first clean water communication port 1111. When in use, the control unit 14 controls the first water pump to work, and the first water pump pumps the water in the clean water chamber 1211 out of the mobile water station 10 through the second clean water communication port 1213 and the first clean water communication port 1111, thereby realizing the clean water adding function.

[0057] Optionally, the first water pump and the control unit 14 are both installed on the water tank 12, and the water tank 12 provides an installation location for the first water pump and the control unit 14. Of course, in other embodiments, the first water pump and the control unit 14 can also be arranged outside the mobile water station 10 to facilitate the transfer of the mobile water station 10.

[0058] Optionally, the first water pump is a diaphragm pump. Of course, in other embodiments, the first water pump may also be other types, which is not limited thereto.

[0059] In one embodiment, referring to FIG. 2, FIG. 4 and FIG. 9, the mobile water station 10 further includes a second water pump, and the second water pump is electrically connected to the control unit 14. The second water pump has a second water inlet and a second water outlet connected to the second water inlet, the second water inlet is connected to the first sewage communication port 1121, and the second water outlet is connected to the sewage chamber 1212. When in use, the control unit 14 controls the second water pump to work, and the second water pump pumps the sewage outside the mobile water station 10 into the sewage chamber 1212 through the first sewage communication port 1121 and the second sewage communication port 1214, thereby realizing the sewage receiving function.

[0060] Optionally, the second water pump is installed on the water tank 12, and the water tank 12 provides an installation position for the second water pump. Of course, in other embodiments, the second water pump can also be arranged outside the mobile water station 10, so that the mobile water station 10 can be transported.

[0061] Optionally, the second water pump is a diaphragm pump. Of course, in other embodiments, the second water pump may also be other types, which is not limited thereto.

[0062] In one embodiment, referring to FIG. 9 , the mobile water station 10 further includes a flow meter 15, which is used to detect the flow rate of clean water flowing out of the clean water chamber 1211. When the flow meter 15 detects that the flow rate of water flowing out of the clean water chamber 1211 is lower than a preset flow rate value, it indicates that the liquid level of the clean water chamber 1211 is low or the clean water chamber 1211 is empty. By setting the flow meter 15, the flow meter 15 can detect the clean water flow rate, and remind the user to replenish water into the clean water chamber 1211 through the clean water replenishment port 1217 in time according to the clean water flow rate.

[0063] Of course, in other embodiments, a liquid level sensor may also be provided in the water tank 12 to detect the liquid level of the clean water chamber 1211 through the liquid level sensor.

[0064] In one embodiment, referring to FIG. 3 and FIG. 4 , the water tank 12 includes a box body 121 and a cover body 122.
