Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to garbage collection devices and cleaning equipment. Background Art

[0002] With economic development and social progress, people's demands for a higher quality of life are increasing, and a variety of cleaning devices have begun to appear in people's lives. Common cleaning devices include vacuum cleaners, robot vacuums, and floor scrubbers. Floor scrubbers are widely used because they can wash and mop at the same time. Floor scrubbers consist of a clean water tank, a water spray system, a floor brush, a motor, and a recovery tank. The water spray system is connected to the clean water tank. When the floor scrubber is in operation, the water spray system sprays water, and the floor brush rubs the floor to complete the cleaning process.

[0003] In the related art, a recovery pipe is installed in the recovery bin, and a filter basket is installed and suspended outside the recovery pipe. The motor provides suction force, which sends the suctioned materials (including airflow, sewage and dry garbage) sucked by the floor brush upward into the recovery pipe. The suctioned materials are sprayed into the filter basket through the top of the recovery pipe. The dry garbage is filtered and collected in the filter basket. The airflow and sewage flow out through the mesh on the filter basket. The sewage remains in the recovery bin, and the airflow is sucked into the motor. Usually, after using the floor scrubber for a period of time, the user needs to remove the filter basket, dump the dry garbage inside, and clean it. However, this process is relatively cumbersome and will cause the user's hands to be dirty. Summary of the Invention

[0021] In one embodiment, the garbage collection device includes a mounting frame located in the recovery chamber and connected to the cavity wall of the recovery chamber, and the filter cover abuts against the limiting member through the suspension ring so that the limiting member abuts against the mounting frame.

[0022] In one embodiment, the limiting member includes a limiting body and a connecting plate, the limiting body enclosing the installation cavity, the connecting plate being connected to one end of the limiting body close to the installation opening along the depth direction, and the connecting plate extending from the limiting body along the first direction toward the side away from the installation cavity, and the filter cover abuts against the connecting plate through the suspension ring so that the connecting plate abuts against the mounting frame.

[0031] In the related solutions proposed in response to the background technology, the suction material flows upward along the recovery pipe and is sprayed into the filter basket through the top of the recovery pipe. This makes it impossible to directly replace the filter basket with a filter bag. Because if it is replaced with a filter bag, the filter bag is installed on the top of the recovery pipe. The filter bag is a closed flexible bag body. If the motor stops suctioning, the bottom of the filter bag away from the bag opening is likely to collapse under the action of gravity and stick to the top of the recovery pipe.

The filter assembly is detachably mounted to the conduit. Since the filter bag is detachably connected to the conduit, when dumping dry waste, one only needs to remove and discard the filter bag and install a new one.

[0066] See Figure 1 The cleaning device provided in this application is a floor scrubber, which includes components such as a garbage collection device 10, a floor brush 20, a rod 30, a handle 40, a body 50, and a battery pack 60. The floor brush 20 is mounted on one end of the rod 30 along its length, and the handle 40 is mounted on the other end of the rod 30. The garbage collection device 10, the body 50, and the battery pack 60 are arranged along the length of the rod 30, and all three are mounted on the rod 30. A motor is installed in the body 50 to provide suction force, the battery pack 60 is used to power the motor and other components, and the handle 40 is for the user to hold.

[0067] See Figure 1 and Figure 3 The garbage collection device 10 has an air inlet 131 for airflow in, and an air outlet 132 for airflow out. The exhaust port of the floor brush 20 is connected to the air inlet 131, and the suction port of the motor is connected to the air outlet 132. When the cleaning device is in operation, the suctioned material sucked in by the floor brush 20 includes airflow and dirt (dirt including dry garbage and sewage). The dirt enters the garbage collection device 10 from the air inlet 131 along with the airflow, and ultimately remains in the garbage collection device 10. The airflow flows through the motor and is discharged from the air outlet 132.

[0068] See Figure 2 、 Figure 5 、 Figure 11 and Figure 13 ,as well as Figure 15In some embodiments, the garbage collection device 10 includes a recycling bin 100, a conduit 500, and a filter assembly. The recycling bin 100 has a recycling chamber 130, the aforementioned air inlet 131, and the air outlet 132. The air inlet 131 is located on the side wall of the recycling bin 100 along a first direction, wherein the first direction is perpendicular to the depth direction of the recycling chamber 130. The filter assembly is located in the recycling chamber 130.

[0069] The filter assembly includes a filter bag 210 having an inner cavity 211 for accommodating waste and a bag opening 2111 connected to the inner cavity 211. The bag opening 2111 is located at one end of the filter bag 210, facing away from the bottom wall of the recovery chamber 130, along the depth direction of the recovery chamber 130. A conduit 500 is installed within the recovery chamber 130, and the filter assembly is detachably connected to the conduit 500. The conduit 500 includes a first section 530 extending along a first direction and a second section 540 extending along the depth direction of the recovery chamber 130. The first section 530 is connected to the second section 540, the bag opening 2111 is connected to the second section 540, and the air inlet 131 is connected to the first section 530.

[0070] In the related solutions proposed in the background technology, the suction material flows upward along the recovery pipe and is sprayed into the filter basket through the top of the recovery pipe. This makes it impossible to directly replace the filter basket with a filter bag. Because if it is replaced with a filter bag, the filter bag is installed at the top of the recovery pipe. The filter bag is a closed flexible bag body. If the motor stops suctioning, the bottom of the filter bag away from the bag opening is likely to collapse under the action of gravity and stick to the top of the recovery pipe. The dry garbage collected in the filter bag may enter the recovery pipe again. Therefore, in this application, the air inlet 131 is improved and set on the side wall of the recovery bin 100 along the first direction, that is, the side of the recovery bin 100. At the same time, the bag opening 2111 of the filter bag 210 is set at the end away from the bottom wall of the recovery chamber 130. If the motor stops suctioning, the dry garbage in the filter bag 210 sinks under the action of gravity and remains in the filter bag 210, thereby solving the above-mentioned problem. On this basis, to achieve communication between the bag openings 2111 facing in different directions and the air inlet 131, a conduit 500 is provided, comprising a first section 530 extending in a first direction and a second section 540 extending in the depth direction of the recovery chamber. The filter assembly is detachably mounted on the conduit 500, enabling communication between the bag openings 2111 facing in different directions and the air inlet 131 through the conduit 500. Because the filter bag 210 is detachably connected to the conduit 500, when dumping dry garbage, one only needs to remove and discard the filter bag 210 and install a new one. There is no need to clean the filter bag 210, thus reducing the risk of getting hands dirty and making the entire process more convenient.

[0071] It should be noted that, from the perspective shown in the drawings, the vertical direction is the depth direction of the recovery chamber 130, that is, the length direction of the rod body 30, and the direction perpendicular to the vertical direction is the first direction. The depth direction mentioned herein refers to the depth direction of the recovery chamber 130.

[0072] See Figure 11 In some embodiments, along the depth direction of the recovery chamber 130 , the conduit 500 is located on a side of the filter bag 210 that is away from the bottom wall of the recovery chamber 130 .

[0073] Specifically, from the perspective of the accompanying drawings, the opening 2111 of the filter bag 210 faces upward, and the air inlet 131 is located vertically above the opening 2111. The duct 500 is positioned entirely above the filter bag 210, creating a more regular arrangement between the two, facilitating installation and saving space. In other embodiments, the duct 500 can be configured in other shapes and positions, simply by adjusting the positions of the air inlet 131 and the opening 2111.

[0074] See Figure 11 and Figure 13 ,as well as Figure 15 and Figure 16 In some embodiments, the first section 530 has a first opening 510 that can be aligned with and connected to the air inlet 131, and the second section 540 has a second opening 520 that can be aligned with and connected to the bag opening 2111. The first opening 510 is located at one end of the first section 530 away from the second section 540 along the first direction, and the second opening 520 is located at one end of the second section 540 away from the first section 530 along the depth direction of the recovery chamber 130.

[0075] Of course, in other embodiments, the conduit 500 may also be configured as a straight tube extending along the first direction.

[0076] See Figure 2 、 Figure 6 、 Figure 11 and Figure 13 ,as well as Figure 15 In some embodiments, the recovery bin 100 includes a bin body 110, and a bin cover 120 located at one end of the bin body 110 away from the bottom wall of the recovery chamber 130 along the depth direction of the recovery chamber 130, the conduit 500 is connected to the bin cover 120, and the filter bag 210 is connected to the bin body 110. The bin body 110 has a connected state connected to the bin cover 120 and a disassembled state separated from the bin cover 120; in the connected state, the bin body 110 and the bin cover 120 define the recovery chamber 130, and the conduit 500 abuts against the filter assembly; in the disassembled state, the conduit 500 is separated from the filter assembly.

[0077] Specifically, from the perspective of the accompanying drawings, the bin cover 120 is detachably connected to the upper end of the bin body 110, and the two can be detachably installed by conventional means such as snap-fitting. The duct 500 extends from the bin cover 120 toward the bin body 110. Preferably, the duct 500 and the bin cover 120 are integrally formed. The filter assembly is located inside the bin body 110. The aforementioned air inlet 131 is provided on the side wall of the bin body 110 along the first direction, and the air outlet 132 is provided on the bin cover 120. A HEPA 121 is installed at the air outlet 132 for re-filtering the outflowing airflow to ensure the cleanliness of the airflow flowing into the motor.

[0078] Furthermore, the filter assembly includes a filter cover 230 fixedly mounted on the bag opening 2111. The filter cover 230 is provided with a notch 231 that communicates with the bag opening 2111. In the connected state, the conduit 500 abuts against the filter cover 230, and the second opening 520 is aligned with and communicates with the notch 231, thereby achieving communication between the air inlet 131 and the bag opening 2111. When the bin cover 120 is separated from the bin body 110, the conduit 500 is also separated from the filter cover 230.

[0079] Since the filter bag 210 is a flexible bag, a filter cover 230 fixedly connected thereto is provided to facilitate the installation of the filter bag 210. From the perspective of the accompanying drawings, the filter bag 210 is fixedly installed at the lower end of the filter cover 230.

[0080] Preferably, a second seal 640 is provided between the second opening 520 and the notch 231, and a third seal 650 is provided between the first opening 510 and the air inlet 131 to enhance the sealing of the connection and prevent dirt and airflow from leaking through the gaps. Preferably, the second seal 640 and the third seal 650 can be integrally molded with the conduit 500 via injection molding to simplify assembly and disassembly.

[0081] See Figure 5 、 Figure 8 、 Figure 10 and Figure 11 ,as well as Figure 15 In some embodiments, the garbage collection device includes a limit member 300 installed in the recovery chamber 130, the limit member 300 has an installation cavity 310, and a connecting hole 320 is provided on the limit member 300. The installation cavity 310 is connected to the recovery chamber 130 through the connecting hole 320, and the filter bag 210 at least partially extends into the installation cavity 310.

[0082] Because the filter bag 210 at least partially extends into the mounting cavity 310 of the stopper 300, the range of motion of the portion of the filter bag 210 that extends into the mounting cavity 310 is limited by the stopper 300. In other words, the stopper 300 can, to a certain extent, restrict the position of the filter bag 210, preventing it from swinging significantly. Therefore, when the motor provides suction, the filter bag 210 and the dry waste collected therein are unlikely to swing significantly within the recovery chamber 130, thereby preventing them from clogging the air outlet 132 of the recovery chamber 130. Airflow can flow out smoothly, and the motor is less likely to malfunction.

[0083] See Figures 10 to 12 ,as well as Figure 15 In some embodiments, one end of the filter bag 210 close to the bag opening 2111 is detachably connected to the recovery bin 100 , and the other end of the filter bag 210 away from the bag opening 2111 extends into the installation cavity 310 .

[0084] Specifically, from the perspective of the accompanying drawings, the bag opening 2111 of the filter bag 210 is located at its upper end, and the lower end of the filter bag extends into the installation cavity 310. It is understandable that if the motor starts suction, since the upper end of the filter bag 210 near the bag opening 2111 is connected to the recovery bin 100, the lower end away from the bag opening 2111 will swing with the largest amplitude. Therefore, extending the lower end away from the bag opening 2111 into the installation cavity 310 can more effectively limit the swing of the filter bag 210. Of course, in other embodiments, the filter bag 210 can also be passed through the installation cavity 310 so that its upper end near the bag opening 2111 and the lower end away from the bag opening 2111 are exposed outside the installation cavity 310, and the area between these two ends is accommodated in the installation cavity 310.

[0085] Continue reading Figures 10 to 12 ,as well as Figure 15 Preferably, in some embodiments, the filter bag 210 is completely inserted into the installation cavity 310. In this way, the swing of the filter bag 210 will be completely limited by the limiting member 300, and the limiting effect is better.

[0086] Continue reading Figures 10 to 12 ,as well as Figure 15 In some embodiments, the limiting member 300 extends along the depth direction of the recovery chamber 130, and the limiting member 300 has an installation opening 311 at one end of the chamber bottom wall away from the recovery chamber 130 along the depth direction of the recovery chamber 130, the filter cover 230 covers the installation opening 311, and the filter bag 210 extends into the installation chamber 310 through the installation opening 311.

[0087] Specifically, from the perspective of the accompanying drawings, the limiting member 300 extends in the vertical direction, and its upper end has a mounting opening 311 connected to the mounting cavity 310. The filter bag 210 can extend downward from the mounting opening 311 into the mounting cavity 310. The size of the filter cover 230 matches the mounting opening 311, and it can block the mounting opening 311. The cross-section of the mounting cavity 310 along the vertical direction is elliptical. Of course, in other embodiments, the limiting member 300 can also be set to other shapes and placement forms. For example, the cross-section of the mounting cavity 310 along the vertical direction can also be circular or polygonal, as long as the swing of the filter bag 210 can be restricted.

[0088] See Figure 8 In some embodiments, a plurality of communication holes 320 are provided on the bottom wall of the limiting member 300 away from the installation opening 311 along the depth direction of the recovery chamber 130 and the side wall along the first direction.

[0089] Specifically, the connecting holes 320 can be in the form of elongated strips, ovals, circles, polygons, or other shapes. Multiple connecting holes 320 are evenly spaced, and the retaining member 300 is hollowed out as a whole. Air and sewage flowing out through the mesh holes in the filter bag 210 can flow out through each of the connecting holes 320, thereby ensuring a smoother outflow process.

[0090] See Figures 10 to 12 As previously mentioned, the end of the filter bag 210 near the bag opening 2111 is detachably connected to the recovery bin 100. Furthermore, in some embodiments, when the bin body 110 is connected to the bin cover 120, the end of the filter bag 210 near the bag opening 2111 is connected to the stopper 300.

[0091] Specifically, from the perspective of the accompanying drawings, the upper end of the filter bag 210 is detachably connected to the upper end of the limiting member 200 , and the limiting member 200 is detachably connected to the recovery bin 100 .

[0092] See Figure 8 、 Figure 9 and Figure 12 ,as well as Figure 15 Furthermore, in some embodiments, the filter assembly includes a suspension ring 220 connected to one end of the filter bag 210 near the bag opening 2111, the suspension ring 220 extends from the bag opening 2111 along a first direction toward the side away from the inner cavity 211, and the suspension ring 220 is fixedly connected to the filter cover 230 along one side of its own thickness direction. The filter cover 230 can be abutted against the limit member 300 through the suspension ring 220 along the side of its own thickness direction away from the filter cover 230.

[0093] Specifically, from the perspective of the accompanying drawings, the suspension ring 220 is annular and surrounds the outer side of the bag opening 2111 at the upper end of the filter bag 210. The thickness of the suspension ring 220 corresponds to the depth of the aforementioned recovery chamber 130. The upper end surface of the suspension ring 220 is fixedly connected to the lower end surface of the filter cover 230. The filter cover 230 can abut against the stopper 300 through the lower end surface of the suspension ring 220, thereby suspending the filter bag 210 connected to the suspension ring 220 within the installation chamber 310.

[0094] Preferably, the hanging ring 220 and the filter bag 210 are made of the same material and are integrally formed. The hanging ring 220 can be formed by folding the opening of a mesh bag outward. Specifically, both are made of white PP non-woven fabric or white PA mesh with a mesh size of 30 mesh.

[0095] In other embodiments, the suspension ring 220 may also be made of materials such as hard plastic. In this way, the filter bag 210 can be installed directly through the hard suspension ring 220 without providing the filter cover 230 .

[0096] In some embodiments, the suspension ring 220 is fixed to the filter cover 230 by ultrasonic welding.

[0097] In some embodiments, the material of the limiting member 300 is transparent ABS.

[0098] See Figure 8 、 Figure 9 and Figure 12 In other embodiments, the hanging ring 220 can be removed, and the filter bag 210 near the bag opening 2111 can be directly clamped between the filter cover 230 and the limiter 300. In this way, one component can be reduced, reducing costs, and users can also directly purchase common filter bags for replacement, which is more versatile. Specifically, the filter cover 230 and the limiter 300 can be fixed by snapping together, so that the filter bag 210 near the bag opening 2111 is clamped between the two. For example, a clamping block can be provided on the filter cover 230, and a clamping slot can be provided on the limiter 300, and the clamping block can be clamped into the clamping slot. Alternatively, the positions of the clamping block and the clamping slot can be interchanged.

[0099] See Figure 7 、 Figure 8 and Figure 12 In some embodiments, the garbage collection device 10 includes a mounting frame 400 located in the recovery chamber 130 and connected to the cavity wall of the recovery chamber 130, the limiting member 300 is installed in the mounting frame 400, and the filter cover 230 can be abutted against the limiting member 300 through the suspension ring 220 so that the limiting member 300 abuts against the mounting frame 400.

[0100] Specifically, the mounting frame 400 has an interference fit with the sidewalls of the recovery chamber 130. The mounting frame 400 includes a top plate 430 extending in a first direction. The top plate 430 is provided with a mounting hole 431, through which the retaining member 300 extends downwardly into the mounting frame 400. The filter cover 230 can abut the retaining member 300 via the suspension ring 220, causing the retaining member 300 to abut against the top plate 430, thereby suspending the retaining member 300 and the filter bag 210 within the mounting frame 400.

[0101] See Figure 8 、 Figures 10 to 12 ,as well as Figure 15 Furthermore, in some embodiments, the limiting member 300 includes a limiting body 330 and a connecting plate 340. The limiting body 330 encloses an installation cavity 310. The connecting plate 340 is connected to one end of the limiting body 330 close to the installation opening 311 along the depth direction of the recovery cavity 130, and the connecting plate 340 extends from the limiting body 330 along the first direction toward the side away from the installation cavity 310. The filter cover 230 can be abutted against the connecting plate 340 through the suspension ring 220 so that the connecting plate 340 abuts against the mounting frame 400.

[0102] Specifically, the retaining member 300 has a similar shape to the expanded filter bag 210. The bottom and side walls of the retaining body 330 define a mounting cavity 310. The connecting plate 340 is annular and surrounds the mounting opening 311 at the top of the retaining body 330. The filter bag 210 extends into the retaining body 330, and the suspension ring 220 is suspended from the connecting plate 340. The filter cover 230 abuts the connecting plate 340 via the suspension ring 220, thereby abutting the top plate 430 of the mounting bracket 400.

[0103] See Figure 12 Preferably, an L-shaped first seal 630 is provided between the connecting plate 340 and the top plate 430 to protect the connecting plate 340 and the top plate 430 from being crushed. The filter cover 230 abuts against the connecting plate 340 via the suspension ring 220, so that the connecting plate 340 abuts against the first seal 630, and further abuts against the top plate 430 of the mounting bracket 400.

[0104] See Figure 5 、 Figure 7 and Figure 11 Furthermore, in some embodiments, the mounting frame 400 includes a baffle 410 extending along the depth direction of the recovery chamber 130, and the recovery chamber 130 includes a first space 133 located on one side of the baffle 410 along its own thickness direction, and a second space 134 located on the other side. The first space 133, the second space 134, and the air outlet 132 are connected in sequence, and the filter bag 210 is installed in the first space 133.

[0105] Specifically, the air inlet 131 is located in the first space 133; the air outlet 132 is partially located in the second space 134 and partially located in the first space 133, but the air outlet 132 is only connected to the second space 134, and not to the first space 133. The baffle 410 is an arc-shaped plate. In other embodiments, the baffle 410 can also be a straight plate. There is a gap between the baffle 410 and the side wall of the recovery chamber 130, and the first space 133 and the second space 134 located on both sides of the baffle 410 can be connected through the gap. The limiter 300 and the filter assembly are both located in the first space 133, and the airflow flowing out of the filter bag 210 eventually flows to the second space 134, and flows out from the second space 134 toward the air outlet 132. In the above embodiment, the filter bag 210 and the air inlet 131 are located in the first space 133, and the air outlet 132 is connected to the second space 134, rather than being directly connected to the air inlet 131 or the first space 133. In this way, the airflow has a longer path when flowing from the air inlet 131 to the air outlet 132, and can stay in the recovery chamber 130 for a longer time, so that the dirt can be fully filtered through the filter bag 210, and the filtering effect is better.

[0106] See Figure 5 、 Figure 7 and Figure 12 Furthermore, in some embodiments, the mounting frame 400 also includes a bottom plate 420 and a side plate 440, the top plate 430 and the bottom plate 420 are arranged at intervals along the depth direction of the recovery chamber 130, the baffle 410 is connected to the bottom plate 420 and the top plate 430, and the side plate 440 extending along the depth direction of the recovery chamber 130 extends from the top plate 430 toward the bottom plate 420, the side plate 440 and the bottom plate 420 are both in contact with the cavity wall of the recovery chamber 130, there is a gap between the baffle 410 and the cavity wall of the recovery chamber 130, a through hole is provided on the bottom plate 420, and the limiting body 330 extends between the baffle 410, the bottom plate 420 and the side plate 440.

[0107] Specifically, the top plate 430 and the bottom plate 420 both extend along a first direction. From the perspective of the accompanying drawings, the top plate 430 is connected to the top end of the baffle 410, and the bottom plate 420 is connected to the bottom end of the baffle 410. The top surface of the top plate 430 is also provided with a circle of upwardly extending vertical plates 460, which are arranged around the outside of the mounting hole 431. The filter cover 230, the filter bag 210, and the retaining member 300 are all accommodated in the area inside the vertical plates 460. The area on the top plate 430 located inside the vertical plates 460 is used to suspend the retaining member 300 and the filter bag 210. The side plates 440 are curved, matching the shape and size of the sidewalls of the recovery chamber 130, allowing them to abut against the sidewalls of the recovery chamber 130. The outer edges of the bottom plate 420 are curved, matching the shape and size of the sidewalls of the recovery chamber 130, allowing them to abut against the sidewalls of the recovery chamber 130. A first through hole 421 and a second through hole 422 are provided on the bottom plate 420. The first through hole 421 is located in the first space 133, and the second through hole 422 is located in the second space 134. Sewage flowing out of the filter bag 210 can flow through the first through hole 421 under the action of gravity and be stored in the space below the bottom plate 420. The second through hole 422 is used to achieve air pressure balance. Of the airflow flowing out of the filter bag 210, a portion flows through the first through hole 421 to the space below the bottom plate 420, and then flows into the second space 134 through the second through hole 422. The other portion flows directly into the second space 134 from the gap between the baffle 410 and the side wall of the recovery chamber 130.

[0108] The edge of the bottom plate 420 is also connected to an upwardly extending first extension plate 471. The upper edge of the first extension plate 471 is connected to a second extension plate 472 substantially parallel to the bottom plate 420. Both the bottom plate 420 and the second extension plate 472 abut against the sidewalls of the recovery chamber 130. The bottom plate 420, the first extension plate 471, and the second extension plate 472 define a groove 473. A fourth sealing member 660 is inserted into the groove 473 to enhance the seal between the bottom plate 420, the first extension plate 471, and the sidewalls of the recovery chamber 130. The limiting body 330 extends into the space between the second extension plate 472, the first extension plate 471, the bottom plate 420, the baffle 410, the top plate 430, and the side plates 440.

[0109] In the embodiment shown in the drawings, the first space 133 is open on the side facing away from the second space 134, and the lower end of the side plate 440 does not extend to connect with the second extension plate 472. In other embodiments, the lower end of the side plate 440 may also extend to connect with the second extension plate 472.

[0110] See Figure 5In some embodiments, a duckbill valve 620 is provided at the first through hole 421. When impacted by water flow, the duckbill valve 620 can open, allowing sewage to flow through the duckbill valve 620 toward the lower side of the bottom plate 420. When there is no water flow impact, the duckbill valve 620 automatically closes, preventing sewage from flowing upward from the lower side of the bottom plate 420. It should be noted that although the second through hole 422 is also provided on the bottom plate 420, because during use of the cleaning device, the first through hole 421 is located on the side close to the ground and the second through hole 422 is located on the side away from the ground, sewage from the lower side of the bottom plate 420 is not easily able to flow back through the second through hole 422.

[0111] See Figure 5 、 Figure 7 and Figure 12 In other embodiments, the limiting member 300 and the mounting member 400 may be integrally formed into one component to simplify the assembly and disassembly process. Figure 12 Based on the illustrated embodiment, the bottom wall of the limiting body 330 in the limiting member 300 is removed, and the side walls of the limiting body 330 are directly extended downward to form an integral connection with the bottom plate 420 in the mounting frame 400. In this case, the duckbill valve 620 can be eliminated, and several through-holes are directly provided in the bottom plate 420 to connect the space above and below the bottom plate 420, allowing sewage to flow through these through-holes to the bottom of the bottom plate 420.

[0112] See Figure 5 、 Figure 7 and Figure 10 In some embodiments, a defoaming member 610 is provided in the second space 134 , and the airflow out of the filter bag 210 flows toward the air outlet 132 through the defoaming member 610 .

[0113] If detergent is added during the use of the floor scrubber, foam may be present in the sucked-in sewage. Since the foam is relatively light, even if the foam has exceeded the upper limit of the water level, the water level sensor provided in the recovery chamber 130 may not be able to accurately sense and alarm. Therefore, foam may be sucked into the motor, and the motor may malfunction. In this embodiment, by providing a defoaming component 610, after the sewage is discharged from the filter bag 210 and retained in the recovery chamber 130, if there is foam floating on the surface of the sewage, when the water level gradually rises to the point where the foam contacts the defoaming component 610, the defoaming component 610 will absorb the foam, thereby reducing the risk of the foam being sucked into the motor together with the airflow when it approaches the air outlet 132, and the motor is less likely to malfunction.

[0114] See Figure 5 、 Figure 7 、 Figure 10 and Figure 11In some embodiments, the baffle 410 is provided with a plurality of hollow mounting plates 450 extending toward the second space 134 and abutting against the cavity wall of the recovery chamber 130. The plurality of mounting plates 450 surround a mounting groove 451, and the defoaming member 610 is stuck in the mounting groove 451.

[0115] Specifically, the mounting plate 450 is provided with a plurality of holes, forming a hollowed-out shape, through which airflow and wastewater can flow. The shape and dimensions of the end of the mounting plate 450 facing away from the baffle 410 match the sidewalls of the recovery chamber 130, allowing the edge of the mounting plate 450 to abut against the sidewalls of the recovery chamber 130. The side of the mounting groove 451 facing away from the baffle 410 is open, allowing the defoaming element 610 to be inserted into the mounting groove 451 for installation.

[0116] As can be understood, since air flows out of the recovery chamber 130 through the air outlet 132 and into the motor's intake port, the closer the foam is to the air outlet 132 during motor operation, the more likely it is to be drawn into the motor. Therefore, the risk area for foam to be drawn into the motor is primarily the end area near the air outlet 132 in the direction of airflow. Placing the foam removal element 610 in the second space 134, closer to the air outlet 132, can more accurately address the issue of foam being easily drawn into the motor.

[0117] See Figure 11 In some embodiments, the defoaming member 610 is located outside the suction range of the motor, where the suction range is the range within which the motor can suck in liquid.

[0118] As previously mentioned, placing the foam removal member 610 in the second space 134, closer to the air outlet 132, can more accurately address the issue of foam being easily inhaled. Furthermore, within the second space 134, the foam removal member 610 is positioned farther from the air outlet 132, placing it outside the motor's suction range. Because the foam removal member 610 is outside the motor's suction range, foam is absorbed by the member 610 even when it's farther from the air outlet 132, effectively facilitating foam absorption and further improving safety.

[0119] Furthermore, the distance between the center position of the defoaming member 610 and the air outlet 132 in the up-down direction is not greater than a preset length, and the preset length s is in the range of 90 mm ≤ s ≤ 110 mm.

[0120] See Figure 10 and Figure 11 In some embodiments, a plurality of defoaming members 610 arranged along the depth direction are provided in the recovery chamber 130 .

[0121] Specifically, from the perspective of the accompanying drawings, the recovery chamber 130 is provided with multiple defoaming members 610 arranged vertically. For example, in the embodiment shown in the accompanying drawings, two defoaming members 610 are provided, arranged vertically. By providing multiple defoaming members 610, the adsorption capacity can be enhanced, further reducing the risk of foam being sucked into the motor.

[0122] In some embodiments, the foam eliminating member 610 is a sponge, and the porous material of the sponge can achieve the purpose of blocking and absorbing foam.

[0123] In some embodiments, the sponge is larger than the mounting groove 451 and has an interference fit with the wall of the mounting groove 451. The sponge has a certain elasticity, so it is only necessary to provide a mounting groove 451 that is slightly smaller than the foam removal member 610. The foam removal member 610 can be fixed by its resilience, thus simplifying the fixing structure and installation method.

[0124] In some embodiments, the mesh size of the foam removal member 610 is 30 mesh.

[0125] In other embodiments, other porous materials may also be used to make the defoaming member 610 .

[0126] See Figure 5 、 Figure 11 and Figure 12 In some embodiments, the filter assembly includes a handle 240 protruding from the filter cover 230 toward a side away from the filter bag 210 , and the handle 240 is located on the outside of the conduit 500 .

[0127] Specifically, from the perspective of the accompanying drawings, the handle 240 protrudes upward from the filter cover 230. Since the handle 240 is located on the outside of the conduit 500, and the dirt and air flow into the filter bag 210 through the conduit 500, the dirt will not touch the handle 240 during the flow process. After being filtered by the filter bag 210, the dry garbage is retained in the filter bag 210, the sewage is retained at the bottom of the recovery chamber 130, and the air flow flows out toward the air outlet 132. During the outflow of the airflow, since the airflow at this time is already relatively clean, even if it touches the handle 240, it will not cause pollution to the handle 240. Therefore, when the user lifts the handle 240 to take out the filter cover 230 and the filter bag 210, it will not get his hands dirty, and the user experience will be better.

[0128] Preferably, two handles 240 are symmetrically arranged on the filter cover 230, and the conduit 500 is located between the two handles 240. The user can pull the two handles 240 at the same time to take out the filter bag 210, and the operation process is more stable.

[0129] In some embodiments, see Figure 4 、 Figure 13 and Figure 14The water level detection assembly includes a probe 710 connected to the bin body 110 and a connecting terminal 720 connected to the bin cover 120. The probe 710 contacts and is electrically connected to the connecting terminal 720. The connecting terminal 720 and an end of the probe 710 close to the connecting terminal 720 are located outside the conduit 500.

[0130] Specifically, the connection terminal 720 and the probe 710 both extend in the vertical direction. The lower end of the probe 710 can be inserted into the water to detect the water level, and the upper end of the probe 710 is used to contact and electrically connect with the connection terminal 720 to transmit a signal to the connection terminal 720. The end of the probe 710 closest to the connection terminal 720 is the upper end of the probe 710. When the upper end of the probe 710 and the connection terminal 720 are both located outside the conduit 500, waste will not hit the connection area between the probe 710 and the connection terminal 720 during the process of flowing through the conduit 500, thereby reducing the chance of water intrusion into this area and further reducing the probability of a short circuit in the connection area.

[0131] In addition, compared to the method of setting the entire water level detection component on the bin cover 120 and extending it from the bin cover 120 into the bin body 110, in this embodiment, since the connecting terminal 720 and the probe 710 are set separately, it is more convenient to install the bin cover 120. It is only necessary to make the connecting terminal 720 contact with the probe 710.

[0132] See Figure 5 、 Figure 7 、 Figure 10 and Figure 13 In some embodiments, one end of the probe 710 that passes through the mounting bracket 400 along the depth direction of the recovery chamber 130 protrudes from the mounting bracket 400 toward the connection terminal 720, and the other end protrudes from the mounting bracket 400 toward the bottom wall of the recovery chamber 130, and the connection terminal 720 extends from the compartment cover 120 toward the probe 710.

[0133] Specifically, a long hole 480 is provided on the mounting frame 400, which passes through the long hole 480 in the up and down directions. The probe 710 passes through the long hole 480 in the up and down directions. The upper end of the probe 710 protrudes upward to above the top plate 430 to facilitate contact and electrical connection with the connecting terminal 720; the lower end of the probe 710 protrudes downward to below the bottom plate 420 to facilitate contact with sewage and detect the water level.

[0134] See Figure 5 and Figure 14 Preferably, in some embodiments, the connection terminal 720 and the compartment cover 120 are connected via an elastic member 730 , and the probe 710 elastically abuts against the connection terminal 720 .

[0135] Specifically, the cover 120 is provided with a connection hole 122, into which the connection terminal 720 is mounted. The elastic member 730 is also located within the connection hole 122 and sleeved over the exterior of the connection terminal 720. From the perspective of the accompanying drawings, when the housing 110 is not yet connected to the cover 120, the lower end of the connection terminal 720 extends beyond the connection hole 122. When the housing 110 is connected to the cover 120, the upper end of the probe 710 abuts against the lower end of the connection terminal 720, compressing the elastic member 730 and causing the connection terminal 720 to retract into the connection hole 122. This allows the probe 710 and the connection terminal 720 to elastically abut against each other when in contact, preventing wear caused by hard contact and improving the fit during contact.

[0136] See Figure 1 and Figure 2 The garbage collection device also includes a recovery pipe 800 located outside the recovery bin 100 , one end of the recovery pipe 800 is aligned with and connected to the air inlet 131 , and the other end is used to communicate with the discharge outlet of the floor brush 20 .

[0137] Specifically, the recovery tube 800 is installed within the rod body 30, and the recovery chamber 100 is detachably connected to the body 50. Compared to the structure in the related art where the recovery tube 800 is built into the recovery chamber 130, in this embodiment, since the recovery tube 800 is located outside the recovery chamber 100, after the recovery chamber 100 is removed, the internal structure is simpler and the cleaning is more thorough. In addition, the volume of the recovery chamber 130 can be fully used to accommodate sewage and garbage, resulting in a larger capacity.

[0138] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0139] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
