[0032] See Figure 1 In one embodiment of the present invention, a wastewater tank 100 is provided, which is used in a floor scrubber 200. When the floor scrubber 200 is working, it sprays water onto the roller brush, and the floor is cleaned by the rotation of the water-laden roller brush. At the same time, the wastewater in the roller brush is squeezed out by the scraper. Finally, the wastewater on the floor and the wastewater squeezed out from the roller brush are sucked into the wastewater tank 100 by the power source. The wastewater tank 100 is used to separate the sucked-in gas, liquid and solid, and also to collect the separated wastewater, thus completing one cleaning process.

[0033] The sewage tank 100 comprises a sewage tank body 10 and an electrode assembly 30. The sewage tank body 10 is internally formed with a sewage cavity 11 for collecting separated sewage. The electrode assembly 30 comprises a bracket 34 and an electrode 32. The bracket 34 is wrapped outside the electrode 32. One end of the bracket 34 extends into the sewage cavity 11, and the other end of the bracket 34 is fixedly connected to the sewage tank body 10. The one end of the bracket 34 extending into the sewage cavity 11 is provided with a detection port 35 for exposing the electrode 32. The liquid level can be detected by contacting the sewage in the sewage tank 100 through the detection port 35.

[0034] In this way, the electrode 32 is wrapped by the bracket 34 to form the electrode assembly 30, so as to protect the electrode 32 by the bracket 34. The electrode assembly 30 can be conveniently fixedly assembled to the sewage tank body 10 by the bracket 34, so as to prevent the electrode assembly 30 from shaking during the movement of the scrubber 200, and the liquid level in the sewage tank 100 can be effectively and accurately detected by the electrode assembly 30. Meanwhile, when the electrode assembly 30 needs to be cleaned, the electrode assembly 30 can be conveniently disassembled from the sewage tank body 10 for cleaning. Only the bracket 34 wrapped outside needs to be cleaned, so that the electrode assembly 30 is convenient to clean.

[0035] Optionally, the electrode assembly 30 comprises two electrodes arranged in opposite directions and used as positive and negative electrodes for sewage detection. Further, the electrode 32 is a metal piece, and the bracket 34 is an injection molded bracket. In the manufacturing process, the bracket 34 can be wrapped outside the electrode 32 by an injection molding process to form the electrode assembly 30.

[0036] In some embodiments, the bracket 34 comprises a wrapping section 341 and an assembling section 343. The wrapping section 341 is wrapped outside the electrode 32. One end of the wrapping section 341 extends into the sewage cavity 11, and the other end of the wrapping section 341 is located outside the sewage cavity 11 and connected to the assembling section 343. The assembling section 343 is connected to the sewage tank body 10. The one end of the wrapping section 341 extending into the sewage cavity 11 is provided with the detection port 35. In this way, the electrode 32 is wrapped and protected by the wrapping section 341 of the bracket 34. The detection port 35 is provided on the wrapping section 341 to allow the electrode 32 to be exposed for liquid level detection. Meanwhile, the assembling section 343 connected to the wrapping section 341 is located outside the sewage cavity 11 and connected to the sewage tank body 10, so as to fixedly assemble the bracket 34 and the electrode assembly 30.

[0037] Further, the one end of the wrapping section 341 extending out of the sewage cavity 11 is provided with a mating port for exposing the electrode 32. The contact 220 is abutted at the mating port and contacts the exposed electrode 32 at the mating port, so as to realize the electrical connection between the contact 220 and the electrode 32, and then the electrode 32 can be connected to the control circuit.

[0038] In some embodiments, the sewage tank 100 further comprises a separator 50, which is arranged in the sewage cavity 11, and the electrode assembly 30 is fixedly attached to the side wall of the separator 50. That is, even if the electrode assembly 30 is fixedly attached to the side wall of the separation air duct 55, the electrode assembly 30 is prevented from extending into the middle of the separation air duct 55 on the side of the separator 50, thereby preventing the electrode assembly 30 from affecting the flow of the air flow in the separation air duct 55, and preventing the electrode assembly 30 from affecting the separation effect.

[0039] Further, the separator 50 comprises a separator body 52 and a limiting plate 54, which is arranged on the outer periphery of the separator body 52. The electrode assembly 30 is attached to the separator body 52 through the limiting plate 54. In this way, the electrode assembly 30 is attached to the side wall of the separator body 52, preventing the electrode assembly 30 from extending into the separation air duct 55 formed by the limiting plate 54. In addition, the limiting plate 54 can further limit and fix the electrode assembly 30, preventing the electrode assembly 30 from shaking under the action of the air flow, and ensuring the accuracy of the detection of the electrode assembly 30.

[0040] Further, the limiting plate 54 is provided with a through hole, and the electrode assembly 30 is arranged through the through hole.

[0041] In some embodiments, the separator body 52 is used to guide the air flow into the upper part of the limiting plate 54, and the limiting plate 54 separates the gas from the solid and liquid, so as to separate the solid and liquid in the air flow and leave them in the sewage cavity 11, preventing the solid and liquid in the air flow from flowing to the power source and affecting the service life of the power source.

[0042] Specifically, when the inhaled air flow enters the separator body 52, it is turned and flows into the separation air duct 55 formed by the limiting plate 54 through the semispherical air duct in the separator body 52. The solid in the air flow falls onto the lower layer of the limiting plate 54 under the action of centrifugal force after hitting the upper layer of the limiting plate 54, and the moisture in the air flow drips onto the lower layer of the limiting plate 54 under the action of centrifugal force, or hits the side wall of the sewage tank body 10. Finally, the sewage flows from the gap between the limiting plate 54 and the side wall of the sewage tank body 10 to the bottom of the sewage cavity 11, realizing sewage collection, and the solid remains on the lower layer of the limiting plate 54, which can be easily cleaned out of the bottom plate 541 by lifting the separator 50 subsequently. Alternatively, the air inlet channel of the separator body is eccentrically arranged with the semispherical air duct, so as to facilitate the turning of the air flow into the separation air duct 55.

After the airflow enters between the bottom plate 541 and the top plate 543, the solid and liquid fall on the top plate 543 and then fall to the bottom plate 541. The liquid falling to the bottom plate 541 flows to the bottom of the sewage cavity 11 from the gap between the bottom plate 541 and the side wall of the sewage tank body 10, and the sewage hitting the side wall of the sewage tank body 10 also flows to the bottom of the sewage cavity 11, realizing sewage collection. In addition, a filter screen is arranged on the separator body 52. The airflow flowing out of the separation air duct 55 of the limiting plate 54 further passes through the filter screen for further filtration and then flows to the power source.

[0044] In some embodiments, the sewage tank 100 further comprises a sealing piece 60, which is sealed and abuts between the sewage tank body 10 and the end of the bracket 34 located outside the sewage tank 100, so as to seal the sewage tank 100 through the sealing piece 60, prevent the water in the sewage tank 100 from flowing out through the opening of the bracket 34, and improve the sealing performance.

[0045] In the above sewage tank 100, the electrode assembly 30 comprises an electrode 32 and a bracket 34 wrapped outside the electrode 32. The electrode assembly 30 can be fixedly assembled on the sewage tank body 10 through the bracket 34, so that the electrode assembly 30 does not shake during use of the scrubber 200, and the detection effect is accurate. In addition, when cleaning the electrode assembly 30 later, the electrode assembly 30 can be conveniently disassembled from the sewage tank body 10 for cleaning the bracket 34, preventing the electrode assembly 30 from being damaged. In addition, the electrode assembly 30 is fixedly abutted on the side wall of the separator 50, preventing the electrode assembly 30 from extending into the separation air duct 55 to affect the airflow flow, and further preventing the electrode assembly 30 from affecting the separation effect.
