They are only for the convenience of description and simplified description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the utility model.

[0036] The terms "first", "second", "third" and the like are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.

[0037] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0038] See also Figure 1 , Figure 2 and Figure 7The embodiment of the first aspect of the utility model provides a dirt recovery device for a floor scrubber, the dirt recovery device 1 comprising a recovery tank 11, a dirt suction pipe 12, a filter assembly 13 and a top cover assembly 14, wherein the recovery tank 11 is detachably mounted on the housing 2 of the floor scrubber, or the main body housing of the floor scrubber; the dirt suction pipe 12 is mounted in the recovery tank 11, passes through the recovery tank 11 and is connected to the recovery tank 11; the filter assembly 13 is sleeved on the outer circumferential surface of the dirt suction pipe 12; the top cover assembly 14 is detachably connected to one end of the recovery tank 11, and is also detachably connected to the housing 2. In this way, when external dirt enters the recovery tank 11 through the dirt suction pipe 12 under the action of negative air pressure, since the filter assembly 13 is arranged in the recovery tank 11, the dirt can be separated into solid and liquid in the recovery tank 11, so that the user can classify and clean the dirt in the recovery tank 11 when the floor scrubber stops using the floor scrubber, especially the solid matter in the dirt, to avoid the situation where the sewer is blocked due to unclear classification of dirt.

[0039] like Figure 5 As shown, the filter assembly 13 includes a filter plate 131 movably mounted on the sewage suction pipe 12. It should be noted that the filter plate 131 always has a tendency to approach the top cover assembly 14 along the sewage suction pipe 12, or in other words, the filter plate 131 is relatively movably connected between the recovery tank 11 and the sewage suction pipe 12. In this way, when the floor scrubber finishes the cleaning function and the user wants to sort and clean the dirt, the dirt recovery device 1 is first removed from the housing 2 through the top cover assembly 14, and then the top cover assembly 14 is pulled out. In the process of the user pulling out the top cover assembly 14, the filter plate 131 of the filter assembly 13 moves from the bottom to the top of the recovery tank 11 to separate the solid and liquid dirt in the recovery tank 11, which is beneficial to reduce the labor intensity and difficulty of the user in sorting and cleaning the dirt.

[0040] Specifically, in this embodiment, the filter assembly 13 further includes a first elastic member 132 for pressing against the filter plate 131 so that the filter plate 131 has a tendency to move along the sewage suction pipe 12. The first elastic member 132 is pressed between the filter plate 131 and the sewage suction pipe 12, and its length direction is parallel to the length direction of the sewage suction pipe 12, so as to provide the filter plate 131 with elastic potential energy to approach the top cover assembly 14 along the length direction of the sewage suction pipe 12. The first elastic member 132 mentioned here may refer to a component that can restore its original shape after a certain degree of deformation, or a component with a certain plasticity, such as a spring.

[0041] Furthermore, if Figure 2 , Figure 5As shown, in order to ensure that the filter plate 131 can move smoothly along the length direction of the suction pipe 12 in the recovery tank 11, the suction pipe 12 includes a guide portion 121, and the guide portion 121 is provided with a guide groove 122 extending along the length direction of the suction pipe 12. The filter assembly 13 also includes a push rod 133, and the push rod 133 includes a limiting portion 133a arranged in the middle of the push rod 133, and the limiting portion 133a protrudes from the outer circumferential surface of the push rod 133. The first elastic member 132 is installed in the guide groove 122, and one end of the first elastic member 132 abuts against the bottom of the guide groove 122, and the other end abuts against the limiting portion 133a. The push rod 133 sequentially penetrates the guide groove 122 and the first elastic member 132 and abuts against the filter plate 131. Since the first elastic member 132 is pre-compressed in the guide groove 122, it has the potential energy to drive the filter plate 131 to move. When the user pulls out the top cover assembly 14 to classify and clean the dirt, the first elastic member 132 pushes the push rod 133 to move the filter plate 131 abutting against the push rod 133 from the bottom to the top of the recovery tank 11 to separate the solid and liquid dirt in the recovery tank 11, which is beneficial to reducing the difficulty and labor intensity of classification and cleaning.

[0042] Specifically, the filter plate 131 is roughly L-shaped, including a filter portion 131a, a first matching portion 131b and a second matching portion 131c. The filter portion 131a is in the shape of a plate, and a plurality of filter holes 131d are provided on the outer surface. Preferably, the diameters of the plurality of filter holes 131d are all greater than 3 mm. The first matching portion 131b is in the shape of a column, and a matching hole 131e is provided in the middle portion so as to be gap-matched with the sewage suction pipe 12. The second matching portion 131c is in the shape of a long strip, and a matching groove 131f extending along the length direction of the second matching portion 131c is provided so as to be relatively movably connected with the guide portion 121 of the sewage suction pipe 12. In order to ensure that the filter plate 131 moves smoothly along the length direction of the sewage suction pipe 12 in the recovery tank 11, it should be noted that the first matching portion 131b and the second matching portion 131c both extend in a direction perpendicular to the plane where the filter portion 131a is located, or in other words, the length direction of the first matching portion 131b and the length direction of the second matching portion 131c are parallel to the length direction of the sewage suction pipe 12.

[0043] See also Figure 3 , Figure 4 and Figure 6The top cover assembly 14 is arranged on the top of the recovery tank 11, and includes an upper cover 141, a lower cover 142, a second elastic member 143 and a button 144 for connecting the housing 2. The button 144 penetrates the upper cover 141 and is movably connected to the lower cover 142 through the second elastic member 143. It should be noted that, in order to ensure that negative air pressure is generated in the waste recovery device 1, both the upper cover 141 and the lower cover 142 are provided with vents (not shown in the figure) so that the sewage suction pipe 12 is connected to the upper cover 141 and the lower cover 142, and is connected to the driving chamber (not shown in the figure) of the floor scrubber through the upper cover 141 and the lower cover 142.

[0044] like Figure 2 , Figure 4 As shown, in order to protect the motor of the floor scrubber, in this embodiment, the top cover assembly 14 also includes a separation cover 145 connected between the lower cover 142 and the filter plate 131. The separation cover 145 is connected to the upper cover 141, the lower cover 142 and the sewage suction pipe 12, which is beneficial to prevent the dirt entering the recovery tank 11 through the sewage suction pipe 12 from flowing into the driving chamber where the motor is installed, and has the function of water vapor isolation. It should be noted that when the filter assembly 13 of the sewage recovery device 1 and the top cover assembly 14 are assembled in the recovery tank 11, the separation cover 145 of the top cover assembly 14 abuts against the filter plate 131 of the filter assembly 13, so that the first elastic member 132 installed in the guide groove 122 is in a preset compression state.

[0045] The second embodiment of the utility model provides a floor scrubber. Figure 7 The floor scrubber may include a core (not shown in the figure), blades (not shown in the figure), a shell 2, and a dirt recovery device 1 as described in the above embodiment, wherein the core and the blades are both accommodated in the shell 2, and the dirt recovery device 1 is detachably mounted on the shell 2. When the floor scrubber performs the cleaning function, the blades rotate at high speed under the drive of the motor to exhaust the air in the floor scrubber, and negative air pressure is generated in the dirt recovery device 1, so that external dirt is sucked into the recovery tank 11 through the dirt suction pipe 12; when the floor scrubber finishes performing the cleaning function, when the user wants to classify and clean the dirt, first, the dirt recovery device 1 is removed from the outer shell 2 by pressing the button 144 of the top cover assembly 14, and then the top cover assembly 14 is pulled out. In the process of the user pulling out the top cover assembly 14, the filter plate 131 of the filter assembly 13 is driven by the first elastic member 132 to move from the bottom of the recovery tank 11 along the length direction of the dirt suction pipe 12 to the top thereof to separate the solid and liquid dirt, so that the above-mentioned floor scrubber has the characteristics of saving time and effort and having a better user experience in classifying and cleaning the dirt in the recovery tank 11.

[0046] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the attached claims.
