[0028] This application discloses a floor cleaning device (e.g., a device for cleaning floors using water or steam). The device has a cleaning base adapted to move along the surface to be cleaned. A driveable rotating roller brush, a removable waste container assembly, etc., are disposed at the cleaning base. In some embodiments, the floor cleaning device may further include a fluid supply system consisting of a water tank, a pump, etc., which can provide water or steam cleaning media to the roller brush when necessary. The device may also include a push rod for maneuvering the cleaning base along the surface to be cleaned.

[0029] See Figure 1 , Figure 2 and Figure 3 The illustration shows a schematic example of a cleaning base for a floor cleaning device. The cleaning base 100 includes a base 1, a roller brush 2 mounted at the front of the base 1 and capable of being driven to rotate about its own axis, a waste container assembly 3 detachably mounted within the base 1, and a roller brush cover 4 mounted on the upper part of the base 1. The base 1 typically also houses a motor (not shown) that drives the roller brush 2 to rotate, and necessary transmission components are arranged between the roller brush 2 and the motor. Alternatively, the motor that drives the roller brush to rotate can be built into the roller brush itself.

[0030] The base 1 is configured to be supported on the surface to be cleaned and to be movable along the surface. The main body of the base 1 is typically assembled from several injection-molded housings. In this example, the front of the base 1 is equipped with a roller brush 2, the middle section can receive a waste container assembly 3, and the rear is configured to accommodate electrical components, such as a motor to drive the roller brush 2, a fluid pump, etc. The rear of the base 1 is also connected to a rotary connector 5, which can be engaged with the upright body of a similar upright floor cleaning device.

[0031] The roller brush cover 4 is removably mounted on the upper part of the base 1. When the roller brush cover 4 is mounted on the upper part of the base 1, the roller brush 2 and the waste container assembly 3 are covered by the roller brush cover 4. The roller brush 2 and the waste container assembly 3 can only be detached from the base 1 after the roller brush cover 4 is removed from the upper part of the base 1. The waste container assembly 3 is disposed adjacent to the roller brush 2 and located in front of the roller brush 2. The waste container assembly 3 is configured to simultaneously receive dry waste and sewage collected from the surface to be cleaned.

[0032] See Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the waste container assembly 3 is a single, integral component, primarily comprising a container body 31 and a lid 32. The container body 31 has an inner dry waste storage chamber 33 for storing dry waste and a waste liquid storage chamber 34 for storing waste liquid. In this example, the dry waste storage chamber 33 is located in front of the waste liquid storage chamber 34. The dry waste storage chamber 33 has a dry waste inlet 331 located at the front of the container body 31. The lid 32 has a waste liquid inlet 341 at its top leading to the waste liquid storage chamber 34. The lid 32 is attached to the upper part of the container body 31 and is configured to open and close the dry waste storage chamber 33 and the waste liquid storage chamber 34 from above.

[0033] Combination Figure 13 The front of the container 31 has a foldable portion 311. This foldable portion 311 is rotatable relative to the rest of the container 31 about an axis parallel to the center line X3. The dry waste collection chamber 33 is defined by this foldable portion 311, and the dry waste inlet 331 is located at the front of the foldable portion 311. With this configuration, the user can rotate the foldable portion 311 to rotate the dry waste inlet 331 to a downward position, thereby emptying the dry waste from the dry waste collection chamber 33.

[0034] A rotating structure 35 is provided between the flip-up portion 311 and the rest of the housing 31. The rotating structure 35 can be a structure such as a rotating shaft and a rotating support hole, defining an axis X3. A positioning structure (not shown) can also be provided between the flip-up portion 311 and the rest of the housing 31. The positioning structure can be a concave-convex positioning structure or a magnetic structure. The positioning structure allows the flip-up portion 311 to maintain a positioning engagement with the rest of the housing 31 when it is not flipped forward, thereby preventing the flip-up portion 311 from accidentally flipping forward. The positioning structure can be located above the rotating structure 35.

[0035] Combination Figure 8 and Figure 9 As shown, the lid 32 includes a front cover 321 and a rear cover 322. The rear cover 322 is located directly above the waste collection chamber 34. The waste inlet 341 is located on the rear cover 322. The rear cover 322 is configured to close the waste collection chamber 34 from above. The rear portion of the rear cover 322 is rotatably connected to the rear portion of the box body 31 about a centerline X1. The front cover 321 is located directly above the dry waste collection chamber 33 and is configured to close the dry waste collection chamber 311 from above. The rear portion of the front cover 321 is rotatably connected to the front portion of the rear cover 322 about a centerline X2. In this example, the centerlines X1, X2, and X3 are parallel to each other and all extend in a horizontal direction.

[0036] A sealing part 37 is fixedly provided on the lower rear part of the front cover 321, and a dust-blocking part 38 is fixedly provided on the lower front part. The front cover 321, the sealing part 37, and the dust-blocking part 38 are an integral component.

[0037] Continue as Figure 3 , Figure 10 and Figure 11 As shown, the sealing part 37 passes through the sewage inlet 341 and extends into the sewage collection chamber 34. When the front cover 321 rotates relative to the rear cover 322 about the axis X2, the sealing part 37 can move between a first position away from the sewage inlet 341 and a second position that seals the sewage inlet 341. When the front cover 321 rotates relative to the rear cover 322 about the axis X2, the dust-blocking part 38 can move between a closed position that shields the dry waste inlet 331 and an open position that is away from the dry waste inlet 331.

[0038] The rear part of the front cover 321 overlaps the front part of the rear cover 322. A pair of return springs 323 are provided between the rear part of the front cover 321 and the front part of the rear cover 322. In this example, both the top of the front cover 321 and the top of the rear cover 322 are provided with protruding handles 3211 and 3221. When the waste box assembly 3 is installed on the base 1 and covered by the roller brush cover 4, the inner wall surface of the roller brush cover 4 will abut against the handle 3211 to apply a force to the handle 3211 to keep the sealing part 37 on the front cover 321 in the first position and the dust blocking part 38 in the open position. When the roller brush cover 4 is removed from the upper side of the waste box assembly 3, the front cover 321, the sealing part 37, and the dust blocking part 38 will be reset by the reset action of the pair of return springs 323, the sealing part 37 will move to the second position, and the dust blocking part 38 will move to the closed position.

[0039] The front cover 321 has an upper surface 3210; when the sealing part 37 is in the first position, the upper surface 3210 gradually slopes from front to back toward the sewage inlet 341. This structure facilitates the diversion of sewage to the sewage inlet 341.

[0040] After the floor cleaning device has finished working, the user can remove the waste container assembly 3 to clean the waste as needed. For example... Figure 12As shown, after the brush cover 4 is removed, the brush cover 4 will leave the handle 3211; the front cover 321 will be able to automatically rotate around the axis X2 under the action of a pair of return springs 323, so that the sealing part 37 moves to the second position and the dust blocking part 38 moves to the closed position. If used for dry waste that needs to be emptied separately from the dry waste collection chamber 311, the front cover 321 is driven to rotate upward around the axis X2 and the rear cover 322 is kept covering the waste liquid collection chamber 34; at this time, the dust blocking part 38 leaves the dry waste inlet 331, and the user can empty the dry waste in the dry waste collection chamber 311; in order to facilitate quick emptying of dry waste, such as Figure 13 As shown, the user can choose to flip the reversible portion 311 of the box 31 forward around the axis X3, thereby helping to quickly empty the dry waste in the dry waste collection compartment 311. If it is necessary to further empty the waste in the liquid collection compartment 34, the user can apply a drive to the rear cover 322 around the axis X1 by applying a drive to the handle 3221. Figure 3 As shown, the lid 32, which includes the front cover 321 and the rear cover 322, can be opened, allowing the waste liquid in the waste liquid collection chamber 34 to be emptied.

[0041] The above embodiments are merely illustrative examples, and those skilled in the art can make equivalent substitutions or improvements within the scope of the claims. Other embodiments, besides the exemplary embodiments shown and described herein, are also covered within the scope of protection of this application.
