[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 4 As shown in the illustration, this embodiment provides a water system including a main housing 1, a first water pump assembly 2, and a second water pump assembly 3. The main housing 1 includes a receiving space, within which both the first water pump assembly 2 and the second water pump assembly 3 are placed. The main housing 1 is provided with a first connector 11, a second connector 12, a third connector 13, and a fourth connector 14, and a first conductive end 15 and a second conductive end 16 are provided on the side wall of the main housing 1. The first water pump assembly 2 includes a first water pump 21. When the first water pump assembly 2 is placed in the receiving space, the inlet and outlet ends of the first water pump 21 are respectively connected to the first connector 11 and the second connector 12, and the first conductive end 15 is electrically connected to the first water pump 21. The power supply in the floor scrubber can then supply power to the first water pump 21 through the first conductive end 15, thus powering on the first water pump 21. The first water pump assembly 2 is detached from the main housing 1. Since the first connector 11 and the second connector 12 are both located on the main housing 1, when the first water pump assembly 2 is completely removed from the main housing 1, the inlet and outlet ends of the first water pump 21 are pulled out from the first connector 11 and the second connector 12 respectively, allowing maintenance personnel to quickly disassemble the first water pump 21. When the first water pump assembly 2 is assembled into the receiving space of the main housing 1, the inlet and outlet ends of the first water pump 21 are respectively inserted into the first connector 11 and the second connector 12, completing the assembly of the water circuit of the first water pump assembly 2.

Maintenance personnel can quickly assemble and disassemble the water circuit and circuit of the first water pump assembly 2, improving the maintenance efficiency of the first water pump assembly 2 in the water system.

[0037] The second water pump assembly 3 includes a second water pump 31. When the second water pump 31 is placed in the receiving space, its inlet and outlet ends are respectively connected to the third connector 13 and the fourth connector 14, and the second conductive end 16 is electrically connected to the second water pump 31. The power supply in the floor scrubber can supply power to the second water pump 31 through the second guide end, thus powering on the second water pump 31. The second water pump assembly 3 is detachably connected to the main housing 1. The third connector 13 and the fourth connector 14 are both located on the main housing 1. When the second water pump assembly 3 is completely removed from the main housing 1, the inlet and outlet ends of the second water pump 31 are pulled out from the third connector 13 and the fourth connector 14, respectively, allowing for quick disassembly of the second water pump 31. When the second water pump assembly 3 is assembled into the receiving space of the main housing 1, the inlet and outlet ends of the second water pump 31 are respectively plugged into the third connector 13 and the fourth connector 14 to complete the assembly of the water circuit of the second water pump assembly 3. The second water pump 31 and the second conductive end 16 are connected to complete the assembly of the circuit of the second water pump assembly 3. Maintenance personnel can quickly complete the assembly and disassembly of the water circuit and circuit of the second water pump assembly 3, improving the maintenance efficiency of the second water pump assembly 3 in the water system.

[0038] Meanwhile, the second connector 12 and the fourth connector 14 are connected through the conduit 4. The second connector 12 is connected to the liquid outlet of the first water pump 21, and the fourth connector 14 is connected to the liquid outlet of the second water pump 31. In this way, the liquid transported by the first water pump 21 and the liquid transported by the second water pump 31 can be mixed. Without affecting the disassembly and assembly efficiency of the first water pump assembly 2 and the second water pump assembly 3, the water circuit of the first water pump assembly 2 and the water circuit of the second water pump assembly 3 are mixed, thereby improving the rationality of the water circuit system design.

[0039] The water system provided in this embodiment, by setting a first connector 11, a second connector 12, a third connector 13, and a fourth connector 14 on the main housing 1, and setting a first conductive end 15 and a second conductive end 16 on the side wall of the main housing 1, when the first water pump assembly 2 is assembled in the receiving space, the inlet and outlet ends of the first water pump 21 are respectively plugged into the first connector 11 and the second connector 12, and the first water pump 21 is electrically connected to the first conductive end 15, thus completing the assembly of the water circuit and circuit of the first water pump assembly 2. When the maintenance personnel disassemble the first water pump assembly 2 from the main housing 1, the inlet and outlet ends of the first water pump 21 are pulled out from the first connector 11 and the second connector 12, respectively, and the first water pump 21 is moved away from the first conductive end 15, thus completing the disassembly of the water circuit and circuit of the first water pump assembly 2; when The second water pump assembly 3 is assembled within the receiving space. The inlet and outlet ends of the second water pump 31 are respectively connected to the third connector 13 and the fourth connector 14, and the second water pump 31 is electrically connected to the second conductive terminal 16, completing the assembly of the water circuit and electrical circuit of the second water pump assembly 3. When the maintenance personnel disassemble the second water pump assembly 3 from the main housing 1, the inlet and outlet ends of the second water pump 31 are pulled out from the third connector 13 and the fourth connector 14, respectively, and the second water pump 31 is moved away from the second conductive terminal 16, completing the disassembly of the water circuit and electrical circuit of the second water pump assembly 3. This allows the water circuit and electrical circuit in both the first water pump 21 and the second water pump 31 to be quickly assembled and disassembled, reducing the difficulty for maintenance personnel in assembling and disassembling the first water pump 21 and the second water pump 31, and improving the work efficiency of the staff. Meanwhile, the second connector 12 and the fourth connector 14 are connected through the conduit 4, so as to mix the water circuit of the first water pump assembly 2 and the water circuit of the second water pump assembly 3 without affecting the disassembly and assembly efficiency of the first water pump assembly 2 and the second water pump assembly 3, thereby improving the rationality of the water circuit system design.

[0040] In this embodiment, the first water pump assembly 2 further includes a first housing 22, in which the first water pump 21 is placed, and the first housing 22 protects the first water pump 21. The first housing 22 is detachably connected to the main housing 1, so removing the first housing 22 from the main housing 1 allows for the removal of the first water pump 21, further reducing the difficulty of disassembling the first water pump 21 and improving the work efficiency of maintenance personnel. The second water pump assembly 3 further includes a second housing 32, in which the second water pump 31 is placed, and the second housing 32 protects the second water pump 31. The second housing 32 is detachably connected to the main housing 1, so removing the second housing 32 from the main housing 1 allows for the removal of the second water pump 31, further reducing the difficulty of disassembling the second water pump 31 and improving the work efficiency of maintenance personnel.

[0041] Furthermore, the side wall of the first housing 22 is provided with a first electrical connection area 221. The power supply terminal of the first water pump 21 is connected to the first electrical connection area 221. When the first housing 22 is placed in the main housing 1, the first electrical connection area 221 and the first conductive terminal 15 are connected.

Similarly, the side wall of the second housing 32 is provided with a second electrical connection area 321. The power supply terminal of the second water pump 31 is connected to the second electrical connection area 321. When the second housing 32 is placed in the main housing 1, the second electrical connection area 321 is electrically connected to the second conductive terminal 16. Through the cooperation of the second electrical connection area 321 and the second conductive terminal 16, the circuit connection of the second water pump 31 is simplified, thereby reducing the difficulty of disassembly and assembly of the second water pump assembly 3.

[0042] The first housing 22 and the second housing 32 are both snap-fitted to the main housing 1. This snap-fit ​​connection is structurally simple, allowing maintenance personnel to quickly disassemble the first housing 22 and the second housing 32 from the main housing 1, while ensuring they can be removed. Specifically, clips can be provided on the first housing 22 and the second housing 32, and snap-fit ​​holes can be provided on the main housing 1.

[0043] Preferably, handles can be provided on both the first box 22 and the second box 32 to facilitate quick and effortless disassembly of both the first box 22 and the second box 32 from the main box 1.

[0044] Furthermore, the first water pump assembly 2 also includes a first sealing block 23, used to seal the connection between the liquid inlet end of the first water pump 21 and the first connector 11, and the connection between the liquid outlet end of the first water pump 21 and the second connector 12.

The two first sealing blocks 23 respectively wrap around the two connection points of the first water pump 21 to achieve a sealing effect. Similarly, the second water pump assembly 3 also includes a second sealing block 33, used to seal the connection between the inlet end of the second water pump 31 and the third connector 13, and the connection between the outlet end of the second water pump 31 and the fourth connector 14, to reduce the risk of liquid leakage when the second water pump 31 is pumping liquid. Specifically, both the first sealing block 23 and the second sealing block 33 can be made of rubber.

[0045] Furthermore, the first housing 22 is provided with two first positioning grooves 222, and two first sealing blocks 23 are respectively placed in the first positioning grooves 222. This allows the first sealing blocks 23 to be positioned and assembled through the first positioning grooves 222, making the assembly of the first water pump assembly 2 more compact and enabling maintenance personnel to quickly assemble the first water pump assembly 2, thus improving their work efficiency. Similarly, the second housing 32 is provided with a second positioning groove 322, and the second sealing block 33 is placed in the second positioning groove 322.
