[0002] In today's society, household cleaning equipment is becoming increasingly popular, and floor scrubbers, as an important member of this category, have become the first choice for many families. However, current floor scrubbers still have some pain points, such as the issue of floor scrubbers cleaning while lying flat. Since floor scrubbers are often equipped with a wastewater tank, when they are lying flat, the water in the wastewater tank can easily backflow into the suction motor, causing damage to the motor.

[0003] To address the aforementioned issues, this application discloses a wastewater tank structure for a floor scrubber that can lie flat. Utility Model Content

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0023] In the description of this application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the component or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Example

[0024] To address the issue that existing horizontal floor scrubbers, when operating in a horizontal position, are prone to backflow of wastewater from the wastewater tank into the suction motor, causing damage, the following measures are proposed: Figure 1-4 As shown, this application discloses a wastewater tank structure for a floor scrubber that can lie flat, including a tank body 10, a tank cover 20, and a filter assembly 30: The tank body 10 has an integrally formed suction channel 11 with open ends along its length, the bottom of which is completely open and the top half-open; the tank cover 20 is detachably mounted on the tank body 10 and has an internal mounting groove 21 with an air extraction port 22, the filter assembly 30 being embedded in the mounting groove 21; a bracket 23 is integrally formed below the tank cover 20, the bracket 23 including components connected to the bottom of the tank cover 20 and in contact with the inner wall of the tank body 10. The vertical section 231 and the horizontal section 232 vertically connected below the vertical section 231 are provided. A separation chamber 233 with one radially open side protrudes from the lower part of the horizontal section 232. The sewage suction channel 11 is inserted into the separation chamber 233, with its top completely open facing the separation chamber 233. A vent frame 234 with the same side as the separation chamber 233 and directly opposite the air intake 22 of the cover 20 protrudes from the upper part of the horizontal section 232. Several sewage channels 2321 are formed on the side surface of the horizontal section 232 opposite to the separation chamber 233 and the vent frame 234. Based on the above structure and referring to... Figure 1As shown, when the housing 10 is in a flat position and the suction motor (the suction motor in this application is another structure of the floor scrubber and is not the subject of this application, so it will not be described in detail here) is performing suction work, the sewage will flow into the suction channel 11 and be blocked by the separation chamber 233 to flow to the bottom of the housing 10. In this state, the distance between the vent frame 234 and the sewage surface is relatively far. Therefore, no sewage will leak out from the vent frame 234 and be drawn away by the suction motor at the suction port of the housing cover 20.

[0025] In order to tightly install the lid 20 to the box body 10, this application provides an inwardly recessed step 24 on the bottom periphery of the lid 20. When the lid 20 is installed on the box body 10, the step 24 of the lid 20 is inserted into the inside of the box body 10.

[0026] Furthermore, in order to achieve better sealing between the cover 20 and the tank body 10, this application provides a first sealing element 25 on the outer periphery of the step 24 of the cover 20, which contacts the inner wall of the tank body 10. Based on the above design, when the sewage tank is in a flat position, the first sealing element 25 can prevent the sewage in the tank body 10 from flowing out.

[0027] Furthermore, the vertical portion 231 and the horizontal portion 232 of the bracket 23 of this application are provided with a second sealing element 26 that contacts the inner wall of the box 10. In this way, the sealing performance of the box cover 20 and the box 10 can be better guaranteed, so that when the box 10 is in a flat position, the sewage in the box 10 can be prevented from flowing out.

[0028] To ensure that the amount of sewage in the sewage tank is within the set value, this application provides water level detection rods 235 for detecting the water level in the tank 10 by inserting them on opposite sides of several sewage channels 2321 on the horizontal part 232 of the support 23. When two water level detection rods 235 detect that the sewage level exceeds the set value, the suction motor will automatically stop running and will no longer perform the suction action.

[0029] In a preferred embodiment, the filter component 30 of this application is a HEPA filter. In actual use, if there are other types of filter components 30 that can meet the filtration function of the HEPA filter, those skilled in the art can adapt them accordingly.

[0030] In order to better match the suction channel 11 with the separation chamber 233, this application provides a protrusion 236 below the separation chamber 233. The protrusion 236 has a through hole 2361 corresponding to the position of the suction channel 11. When the box cover 20 is installed on the box body 10, the suction channel 11 passes through the through hole 2361 into the separation chamber 233.

[0031] In one specific implementation, the present application also provides a baffle 2341 above the vent frame 234 for partially enclosing it. When the suction motor is performing suction, it will suck towards the baffle 2341. In this way, sewage will not pass through the baffle 2341 and enter the suction port of the cover 20, further preventing sewage from flowing into the suction motor.

[0032] In the description of this specification, the references to terms such as "an embodiment," "example," "specific example," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0033] The above embodiments are only for illustrating the technical concept and features of this application, and are intended to enable those skilled in the art to understand the content of this application and implement it accordingly. They should not be used to limit the scope of protection of this application. All equivalent changes or modifications made in accordance with the spirit and essence of this application should be included within the scope of protection of this application.
