[0032] like Figures 1 to 5 As shown, this embodiment discloses a water treatment device, comprising:

[0033] Upper cover 12;

[0034] The water supply module includes a water inlet 21 and a water outlet 22 provided on the upper cover 12 , and a first water pipe 23 connected to the lower end of the water inlet 21 ;

[0035] A cleaning liquid adding module includes a cleaning liquid inlet 31 provided on the upper cover 12, a second water pipe 32 connected to the lower end of the cleaning liquid inlet 31, and a one-way valve 33 provided on the second water pipe 32. The second water pipe 32 is also connected to the first water pipe 23.

[0036] The sewage discharge module includes a sewage inlet 41, a sewage outlet 42, a water pump 43, a third water pipe 44 and a fourth water pipe 45 provided on the upper cover 12. The sewage inlet 41 is connected to the water suction port of the water pump 43 through the third water pipe 44, and the sewage outlet 42 is connected to the water discharge port of the water pump 43 through the fourth water pipe 45.

[0037] The water treatment device of this embodiment is equipped with a water adding module, and the water inlet 21 is connected to the tap water supply end through a pipe, and the water outlet 22 is connected to the base station water supply port of the mopping robot. When the mopping robot needs to mop the floor, the tap water supply end is used to supply water to the base station water supply port of the mopping robot, thereby achieving the effect of continuously supplying water to the base station water supply port of the mopping robot.

[0038] In addition, a cleaning liquid adding module is provided, and the upper end of the cleaning liquid inlet 31 is connected to the cleaning liquid bottle. When mopping the floor, the cleaning liquid in the cleaning liquid bottle is passed into the first water pipe 23 through the second water pipe 32, adding cleaning liquid to the water in the first water pipe 23. Moreover, a one-way valve 33 is also provided to prevent water from flowing back into the cleaning liquid bottle, thereby playing a good anti-backflow protection role.

[0039] In addition, a sewage discharge module is provided, and the upper end of the sewage inlet 41 is connected to the mop washing position below the base station of the mopping robot through a pipe. After the water pump 43 is started, water enters the sewage inlet 41 from the mop washing position through the action of negative pressure, and is finally discharged from the sewage outlet 42, which can quickly remove the sewage in the mop washing position below the base station of the mopping robot.

[0040] Furthermore, the water treatment device also includes a casing 11 assembled with the upper cover 12. The first water pipe 23, the second water pipe 32, the one-way valve 33, the water pump 43, the third water pipe 44 and the fourth water pipe 45 are all located in the casing 11. The structure is compact, which is conducive to the miniaturization development of the water treatment device.

[0041] For further information, please refer to Figure 1 and 2 The water treatment device of this embodiment also includes a circuit board 50 fixed to the lower end of the upper cover 12. The upper cover 12 is provided with a power supply 51 and a sewage switch 52 electrically connected to the circuit board 50. The water pump 43 is electrically connected to the circuit board 50. The power supply 51 is used to control the switch of the water pump 43. When sewage needs to be discharged, the sewage switch 52 can be manually pressed. After the power supply 51 is turned on, the water pump 43 is controlled to turn on. After the water pump 43 is started, water enters the sewage inlet 41 from the mop washing position through the action of negative pressure, and is finally discharged from the sewage outlet 42.

[0042] Please refer to Figure 2 The water adding module also includes a first valve 24 provided on the first water pipe 23. The first valve 24 can be a negative pressure switch valve. One end of the negative pressure switch valve is connected to the tap water channel, and the other end is connected to the water supply port of the sweeping machine base station. When the sweeping machine base station needs water, it will absorb water through the water suction pump inside the base station, thereby causing negative pressure. After the negative pressure switch valve senses the negative pressure, it opens the switch, allowing water to enter the internal water channel of the base station through the action of water pressure, providing clean water to the base station water pump, thereby achieving the purpose of continuously supplying water to the sweeping machine base station.

[0043] Please refer to Figure 5The cleaning liquid adding module also includes a regulating valve 34 arranged on the second water pipe 32. The regulating valve 34 is provided with a knob 341 passing through the upper end of the upper cover 12. The regulating valve 34 is used to control the supply flow of the cleaning liquid. The user can adjust the supply flow of the cleaning liquid through the knob 341, and the operation is simple.

[0044] Furthermore, the one-way valve 33 can adopt a check valve. When the sweeping robot base station needs clean water, the water pump inside the base station will absorb water, and the first valve 24 opens the water supply. At the same time, the other end of the first water pipe 23 is connected to the cleaning liquid bottle through the second water pipe 32, and a check valve is set in the middle of the second water pipe 32. When the water pump inside the base station absorbs water, it will absorb water and cleaning liquid together. When no water is absorbed, the check valve will prevent the clean water from flowing back into the cleaning liquid bottle.

[0045] Please refer to Figures 2 to 4 The sewage discharge module of this embodiment also includes a water tank 46 fixed to the lower end of the upper cover 12 and connected to the sewage inlet 41 and the third water pipe 44, a filter device 47 provided in the water tank 46, and an end cover 48 detachably connected to the upper cover 12 and located at the top of the water tank 46. The sewage inlet 41 is formed at the upper end of the end cover 48. The filter device 47 can adopt a structure consisting of a barrel-shaped frame and a filter net provided on the frame. By providing the filter device 47, impurities in the sewage can be filtered and then the sewage can be discharged.

[0046] Furthermore, the end cover 48 is threadedly connected to the upper cover 12, and the end cover 48 and the upper cover 12 are set to a detachable structure. The user can quickly open the end cover 48 to remove the filter device 47 placed in the water tank 46 and clean the filter device 47 regularly.

[0047] Furthermore, anti-slip grooves are provided on the outer side of the end cover 48, so that the user can avoid slipping when rotating the end cover 48 to open it.

[0048] The water treatment device also includes a sewage sensing module, which includes a sewage sensing port 61 provided on the upper cover 12, a fifth water pipe 62 connected to the lower end of the sewage sensing port 61, and a negative pressure sensor 63 connected to one end of the fifth water pipe 62. The negative pressure sensor 63 is used to sense the internal pressure of the fifth water pipe 62. The negative pressure sensor 63 is also electrically connected to the circuit board 50. The sewage sensing port 61 is connected to the air pump hole of the sweeping machine base station. When the air pump of the sweeping machine base station inhales air, the negative pressure sensor 63 will change from disconnected to connected, and the water pump 43 will be controlled to turn on by the power supply 51. After the water pump 43 is started, the water enters the sewage inlet 41 from the mop washing position through the action of negative pressure, and is finally discharged from the sewage outlet 42. By setting the negative pressure sensor 63, automatic sewage discharge is achieved.
