A filter cartridge 28 matched with the channel opening 27 is provided in the mixing chamber 23, and the channel opening 27 connects the mixing chamber 23 to the clean water tank 12 or the washing liquid tank 13; a water trough 48 and two adjustment plates 3 are provided in the mixing chamber seat 43, the water trough 48 is arranged at the bottom of the mixing channel 44, and a plurality of water outlet holes 32 and a plurality of liquid outlet holes 33 are respectively provided on the two adjustment plates 3; the two adjustment plates 3 are respectively rotatably arranged at the two ends of the water trough 48, and a lifting terminal 47 is provided on the adjustment plate 3, and the two lifting terminals 47 are penetrated into the corresponding matching interfaces 46.

[0053] Two round-mouth slots 14 are provided on the bottom plate of the water tank 1 to install the corresponding control valves 2, and the two round-mouth slots 14 are connected to the clean water tank 12 and the washing liquid tank 13 respectively. The valve seat 21 can be fixedly installed in the round-mouth slot 14 by means of thread, buckle, embedding, etc., and the mixing chamber 23 is connected to the clean water tank 12 or the washing liquid tank 13 through the channel opening 27. Of course, a sealing ring is provided between the valve seat 21 and the round-mouth slot 14 to ensure the sealing. The mixing cavity seat 43 is a component on the cleaning device, which is used for matching and connecting the water tank 1.

[0054] Preferably, the regulating plate 3 is arranged in the mixing channel 44 of the mixing cavity seat 43. When the regulating plate 3 is rotated, the water outlet hole 32 or the liquid outlet hole 33 on the regulating plate 3 can be matched with the water trough 48, so that the matching interface 46 is connected to the mixing channel 44 through the water outlet hole 32 or the liquid outlet hole 33. Of course, the apertures of the several water outlet holes 32 and the liquid outlet holes 33 on the regulating plate 3 are different. The lifting terminal 47 can drive the regulating plate 3 to rotate, so that before installing the water tank 1, the water-liquid ratio entering the mixing channel 44 can be adjusted according to demand. Then, the water tank 1 is installed on the cleaning device, and the two control valves 2 are respectively connected to the matching interfaces 46. The lifting terminals 47 therein resist the one-way valve core 22 to connect the cut-off hole to the mixing chamber 23 and the mixing channel 44. Then, the clean water and washing liquid in the water tank 1 enter the mixing chamber 23 from the channel mouth 27, and then enter the mixing channel 44 through the cut-off hole 24, the water outlet hole 32 / liquid outlet hole 33, and the water trough 48 in turn. After the water and liquid are mixed in proportion, they are transported to the cleaning device from the cleaning liquid outlet 45.

[0055] The above description is only a preferred embodiment of the present utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present utility model patent application are included in the scope of the present utility model patent application.
