For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0057] In related technologies, self-propelled cleaning devices include a mopping component, a water supply component, and a liquid storage tank. When the self-propelled cleaning device is working, the water supply component supplies water to the mopping component, and the liquid storage tank collects the wastewater generated by the mopping component. In practical applications, the liquid storage tank has the problem of not being able to recycle wastewater, leading to a high failure rate for self-propelled cleaning devices.

[0058] Research revealed that the inability of the storage tank to collect wastewater was due to a malfunction in the negative pressure generator connected to it. Furthermore, when disassembling cleaning components (such as mops), because these components are located at the bottom of the main unit, the self-propelled cleaning device needs to be flipped over for removal. When the storage tank is flipped, liquid within it easily enters the negative pressure suction port and is subsequently drawn into the negative pressure generator, affecting its normal operation. Alternatively, during normal cleaning, if the self-propelled cleaning device encounters an object, causing the liquid in the storage tank to agitate, it can also enter the negative pressure suction port and be drawn into the negative pressure generator.

[0059] To address the issue of wastewater not being recyclable in the storage tank, this application proposes a self-moving cleaning device and cleaning system.

[0060] An embodiment of the first aspect of this application provides a self-moving cleaning device, for example, a sweeper. Please refer to... Figures 1 to 3 The self-propelled cleaning device 100 includes a liquid storage box 10, a negative pressure generator 50, and a blocking module 14. The liquid storage box 10 has a negative pressure suction hole 111, and the negative pressure generator 50 is connected to the negative pressure suction hole 111. The blocking module 14 is located inside the liquid storage box 10 and connected to the air inlet 1111 of the negative pressure suction hole 111 to prevent liquid in the liquid storage box 10 from entering the negative pressure suction hole 111.

[0061] Understandably, the liquid storage box 10 can be a sewage box or a clean water box.

[0062] For example, the liquid storage box 10 includes a box body 11 and a cover plate 12. A negative pressure suction hole 111 is provided on the box body 11. The box body 11 and the cover plate 12 form a liquid storage cavity 113. The negative pressure suction hole 111 communicates with the liquid storage cavity 113.

[0063] The negative pressure suction port 111 has an air inlet end 1111 and an air outlet end 1112. For example, the negative pressure suction port 111 is L-shaped, that is, the air inlet of the air inlet end 1111 is arranged upward, and the air outlet of the air outlet end 1112 is arranged in the horizontal direction. The negative pressure generator 50 is connected to the air outlet end 1112 of the negative pressure suction port 111 through a pipeline.

[0064] For example, the negative pressure generator 50 is a vacuum pump.

[0065] The beneficial effects of the self-moving cleaning device 100 provided in this application embodiment are as follows: By setting a blocking module 14 at the air inlet 1111 of the negative pressure suction hole 111 of the liquid storage box 10, the blocking module 14 can effectively prevent the liquid in the liquid storage box 10 from entering the negative pressure suction hole 111, regardless of whether the self-moving cleaning device 100 is upright or upside down. This prevents the liquid from entering the negative pressure generator 50 when the negative pressure generator 50 is drawing negative pressure, ensuring that the negative pressure generator 50 can work normally, and solving the problem that the liquid storage box 10 cannot recycle sewage.

[0066] It should be noted that "upright" means that the chassis of the self-propelled cleaning equipment 100 (on which a walking mechanism, such as drive wheels and casters, is installed) faces the ground, while "inverted" means that the chassis of the self-propelled cleaning equipment 100 is away from the ground.

[0067] In some embodiments, the distance between the top of the blocking module 14 and the liquid storage box 10 is less than the distance between the bottom of the blocking module 14 and the liquid storage box 10. This can be understood as the blocking module 14 being arranged higher up inside the liquid storage box 10. In this way, under normal conditions, liquid is less likely to enter the negative pressure suction hole 111.

[0068] In some embodiments, the liquid storage box 10 includes a box body 11 and a cover plate 12 connected to the box body 11, with the cover plate 12 located on the top of the box body 11; wherein, a negative pressure suction hole 111 is provided on the box body 11, and a blocking module 14 abuts against the cover plate 12.

[0069] In some other embodiments, the negative pressure suction hole 111 and the blocking module 14 are both located on the cover plate 12.

[0070] In some embodiments, the liquid storage box 10 has a preset maximum liquid level, and the height of the air inlet end of the blocking module 14 is higher than the preset maximum liquid level. Because the air inlet end of the blocking module 14 is higher, under normal conditions, liquid is less likely to enter the negative pressure suction hole 111. Here, the air inlet end of the blocking module 14 refers to the position on the blocking module 14 where gas can enter the negative pressure suction hole 111, for example, the position where the waterproof and breathable component 141 is located.

[0071] In some embodiments, a liquid level detection device 16 is provided in the liquid storage box 10. The liquid level detection device 16 generates a full water signal in response to the liquid level reaching a preset maximum liquid level or the liquid storage box 10 being inverted. The negative pressure generator 50 stops working in response to the full water signal. In this way, the negative pressure generator 50 can stop working when the liquid level reaches the preset maximum liquid level or the liquid storage box 10 is inverted, preventing liquid from being drawn into the negative pressure generator 50 through the blocking module 14.

[0072] For example, the liquid level detection device 16 is a liquid level gauge. The liquid level detection device 16 includes a limiting channel, a float, and a Hall sensor. The limiting channel is vertically arranged, and the float is disposed within the limiting channel and can move within the limiting channel. The float rises within the limiting channel in response to a rise in the liquid level. When the liquid storage box 10 is inverted, the float moves within the limiting channel due to gravity.

[0073] Please refer to Figure 3 In some embodiments, the blocking module 14 includes a flexible seal 142 and a waterproof and breathable component 141. The waterproof and breathable component 141 is connected to the flexible seal 142, and the flexible seal 142 is connected to the air inlet 1111 of the negative pressure suction port 111. That is, the waterproof and breathable component 141 is installed at the air inlet 1111 of the negative pressure suction port 111 through the flexible seal 142.

[0074] For example, the flexible seal 142 is a silicone seal or a rubber seal.

[0075] For example, the waterproof and breathable component 141 is bonded and fixed to the flexible seal 142. For instance, the waterproof and breathable component 141 can be bonded and fixed to the flexible seal 142 with double-sided adhesive; or, the waterproof and breathable component 141 can also be bonded and fixed to the flexible seal 142 with glue.

[0076] Understandably, the waterproof and breathable component 141 can be a waterproof and breathable membrane; or, the waterproof and breathable component 141 can also be a dense filter screen, that is, the mesh of the filter screen is small. Due to the surface tension of the liquid itself, it can prevent the liquid from passing through the filter screen, but can ensure the passage of gas.

[0077] Based on the above technical solution, during assembly, the waterproof and breathable component 141 and the flexible sealing component 142 can be fixed together to form the blocking module 14, and then the blocking module 14 can be installed at the air inlet end 1111 of the negative pressure suction hole 111, which is beneficial for assembly.

[0078] In some other embodiments, the blocking module 14 includes only a waterproof and breathable component 141, which is directly fixedly connected to the air inlet 1111 of the negative pressure suction hole 111.

[0079] Please refer to Figure 3 In some embodiments, the liquid storage box 10 includes a box body 11 and a cover plate 12 connected to the box body 11. A negative pressure suction hole 111 is provided on the box body 11. A flexible sealing member 142 abuts against the cover plate 12 and forms an air inlet channel 1424 with the cover plate 12. The air inlet channel 1424 connects the liquid storage cavity 113 of the box body 11 and the side of the waterproof and breathable member 141 facing the cover plate 12.

[0080] For example, one end of the cover plate 12 is rotatably connected to the box body 11, and the other end of the cover plate 12 is snapped onto the box body 11 to facilitate the opening and closing of the cover plate 12. A sealing ring is provided between the cover plate 12 and the box body 11 to ensure the sealing of the cover plate 12 after it is snapped onto the box body 11.

[0081] The air inlet channel 1424 connects the liquid storage chamber 113 of the housing 11 and the waterproof and breathable component 141 on the side facing the cover plate 12, so that when the negative pressure generator 50 draws negative pressure, the gas in the liquid storage chamber 113 can enter the negative pressure suction hole 111 through the air inlet channel 1424 and the waterproof and breathable component 141. Moreover, the air inlet channel 1424 forms a labyrinth structure, making it difficult for the liquid in the liquid storage chamber 113 to enter the side of the waterproof and breathable component 141 facing the cover plate 12.

[0082] Please refer to Figure 3 In some embodiments, the flexible seal 142 is interference-fitted onto the air inlet end 1111 of the negative pressure suction hole 111.

[0083] For example, the inner wall surface of the flexible seal 142 is provided with a sealing ring rib 1425 to prevent liquid in the liquid storage chamber 113 from entering the negative pressure suction hole 111 from the mating point between the flexible seal 142 and the air inlet 1111.

[0084] Understandably, one or more sealing ring ribs 1425 may be provided. When multiple sealing ring ribs 1425 are provided, the multiple sealing ring ribs 1425 are arranged at axial intervals along the flexible seal 142.

[0085] Based on the above technical solution, since the flexible seal 142 has a certain degree of flexibility, it can undergo a certain deformation, which is beneficial for the flexible seal 142 to be connected to the air inlet end 1111 of the negative pressure suction hole 111. Moreover, the flexible seal 142 will not occupy the internal space of the air inlet end 1111 of the negative pressure suction hole 111, which is beneficial for arranging other components inside the air inlet end 1111 of the negative pressure suction hole 111.

[0086] In other embodiments, the flexible seal 142 may also be interference-fitted into the air inlet 1111 of the negative pressure suction port 111.

[0087] Please refer to Figure 4 and Figure 5In some embodiments, the flexible seal 142 includes a sealing body 1421 and a first rib 1422 and a second rib 1423 disposed on the sealing body 1421. The first rib 1422 and the second rib 1423 are arranged radially at intervals along the waterproof and breathable component 141 and abut against the cover plate 12. The first rib 1422 is located inside the second rib 1423. The first rib 1422, the second rib 1423, the sealing body 1421 and the cover plate 12 form an air intake channel 1424.

[0088] The sealing body 1421 is sleeved outside the air inlet 1111 of the negative pressure suction hole 111, the sealing ring rib 1425 is provided on the inner wall surface of the sealing body 1421, and the waterproof and breathable component 141 is bonded and fixed on the sealing body 1421.

[0089] For example, the first rib 1422 and the second rib 1423 are arc-shaped ribs arranged circumferentially along the waterproof and breathable member 141.

[0090] For example, the first rib 1422 and the second rib 1423 are integrally formed with the sealing body 1421.

[0091] Based on the above technical solution, when the liquid in the liquid storage box 10 shakes, it is first blocked by the second rib 1423, and then blocked by the first rib 1422, so as to reduce or avoid the liquid entering the side of the waterproof and breathable component 141 facing the cover plate 12.

[0092] Please refer to Figure 5 In some embodiments, the first rib 1422 is provided with a first notch 14221, the first notch 14221 connecting the air inlet channel 1424 and the waterproof and breathable component 141 on the side facing the cover plate 12; and the second rib 1423 is provided with a second notch 14231 at at least one end in the circumferential direction of the waterproof and breathable component 141, the second notch 14231 connecting the liquid storage cavity 113 of the box body 11 and the air inlet channel 1424.

[0093] For example, the waterproof and breathable component 141 is higher than the bottom wall of the first notch 14221, so that liquid entering the air inlet channel 1424 is less likely to enter the waterproof and breathable component 141 on the side facing the cover plate 12. One or more first notches 14221 may be provided in the circumferential direction of the waterproof and breathable component 141.

[0094] The second rib 1423 has a second notch 14231 at least one end in the circumferential direction of the waterproof and breathable component 141. Understandably, the second rib 1423 has a second notch 14231 at one end, or the second rib 1423 has a second notch 14231 at both ends.

[0095] For example, the second rib 1423 has chamfers at both ends in the circumferential direction of the waterproof and breathable component 141, and the chamfers form a second notch 14231.

[0096] When the negative pressure generator 50 pairs of liquid storage boxes 10 draws negative pressure, the airflow path is as follows: Figure 5 As shown by the arrow, the air in the liquid storage chamber 113 first enters the air intake channel 1424 through the second notch 14231, and then enters the waterproof and breathable part 141 on the side facing the cover plate 12 through the first notch 14221, and finally enters the negative pressure suction hole 111 through the waterproof and breathable part 141.

[0097] In some other embodiments, the first rib 1422 is provided with a first notch 14221, and the second rib 1423 is not provided with a second notch 14231, but is provided with a second through hole; or, the first rib 1422 is not provided with a first notch 14221, but is provided with a first through hole, and the second rib 1423 is provided with a second notch 14231; or, the first rib 1422 is not provided with a first notch 14221, but is provided with a first through hole, and the second rib 1423 is not provided with a second notch 14231, but is provided with a second through hole.

[0098] Please refer to Figure 6 In some embodiments, the flexible seal 142 is further provided with a support member 1426 for supporting the waterproof and breathable member 141.

[0099] For example, the support member 1426 has a cross structure.

[0100] Based on the above technical solution, since the waterproof and breathable component 141 is usually thin and made of flexible material (such as silicone), the waterproof and breathable component 141 is supported by the support component 1426, so that the waterproof and breathable component 141 is not easily deformed when the negative pressure generator 50 draws negative pressure.

[0101] Please refer to Figure 3 In some embodiments, the liquid storage box 10 further includes a one-way valve 15 disposed within the negative pressure suction port 111. The one-way valve 15 is used to prevent backflow.

[0102] For example, the one-way valve 15 is a duckbill valve.

[0103] For example, the one-way valve 15 is installed in the air inlet 1111 of the negative pressure suction port 111.

[0104] Please refer to Figure 1 In some embodiments, the self-moving cleaning device 100 also includes a device body 20 and a cleaning component 30, with the liquid storage box 10 detachably connected to the device body 20; the bottom of the device body 20 is provided with an installation notch 21, and the cleaning component 30 can be installed and removed from the device body 20 through the installation notch 21.

[0105] For example, the mounting notch 21 includes a first mounting notch 211 and a second mounting notch 212, and the cleaning component 30 includes a mopping component 31 and a sweeping component 32. The mopping component 31 is disposed in the first mounting notch 211, and the sweeping component 32 is disposed in the second mounting notch 212. The second mounting notch 212 is located between the first mounting notch 211 and the liquid storage box 10, and the negative pressure suction hole 111 is disposed on the side of the liquid storage box 10 near the mopping component 31.

[0106] Please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 In some embodiments, the liquid storage box 10 has a suction port 112, and the self-moving cleaning device 100 also includes a squeegee 40, which includes a squeegee section 41 for swiping the sewage off the mop 31. The squeegee 40 also has a water collection tank 42 and a drain outlet 43 communicating with the water collection tank 42. The water collection tank 42 is used to collect the sewage scraped off the mop 31. The sewage in the water collection tank 42 can enter the suction port 112 through the drain outlet 43.

[0107] Understandably, the mopping component 31 can be a roller mop or a tracked mop, that is, the mopping component 31 can rotate relative to the main body 20 of the equipment, wherein the rotation axis of the mopping component 31 extends along the first direction X.

[0108] When the liquid storage box 10 is installed on the device body 20, the first direction X is horizontal or nearly horizontal. That is, when the liquid storage box 10 is installed on the device body 20, the rotation axis of the dragging member 31 extends horizontally or nearly horizontally.

[0109] Understandably, the squeegee 40 can be fixed to the equipment body 20 or float on the equipment body 20. During the rotation of the mopping component 31, the mopping component 31 rubs the surface to be cleaned, while the squeegee 41 scrapes off the wastewater from the rotating mopping component 31. When the squeegee 40 is floated on the equipment body 20, the squeegee 40's scraping part 41 is always able to abut against the mopping component 31, ensuring a certain amount of resistance, thereby effectively scraping off the wastewater from the mopping component 31.

[0110] For example, the wiper portion 41 extends along the first direction X, and the size of the wiper portion 41 in the first direction X is greater than or equal to the size of the mop member 31 in the first direction X, so that the wiper portion 41 can cover the entire surface of the mop member 31 during the rotation of the mop member 31.

[0111] For example, the water collection tank 42 extends along the first direction X, and the opening of the water collection tank 42 faces upward.

[0112] For example, the drain outlet 43 is located in the middle or near the middle of the water collection tank 42.

[0113] For example, the drain outlet 43 is a strip-shaped outlet.

[0114] Please refer to Figure 1 and Figure 7 In some embodiments, the liquid storage box 10 further includes a box body 11 and a water receiving tray 13 connected to the box body 11. The sewage suction port 112 is provided on the box body 11. The water receiving tray 13 has a water receiving groove 131, which is connected to the sewage suction port 112. The drain outlet 43 is located above the water receiving groove 131. The sewage in the water collection tank 42 can fall into the water receiving groove 131 through the drain outlet 43 and enter the sewage suction port 112.

[0115] For example, the water tray 13 is integrally connected to the box body 11, that is, the water tray 13 and the box body 11 are integrally formed. Of course, the water tray 13 can also be fixed to the box body 11 by means of adhesive, fastener connection, snap-fit, etc.

[0116] The drain outlet 43 is located above the water receiving tank 131. Wastewater falling through the drain outlet 43 can fall directly into the water receiving tank 131 under the action of gravity, and then be sucked into the liquid storage chamber 113 through the suction port 112. That is, there is no need to set up additional pipes connecting the drain outlet 43 and the suction port 112, which simplifies the structure.

[0117] In some other embodiments, the water receiving tray 13 may not be provided. The drain outlet 43 is connected to the suction port 112 through a pipeline. That is, the sewage in the water collection tank 42 enters the liquid storage chamber 113 through the drain outlet 43, the pipeline, and the suction port 112.

[0118] Please refer to Figure 8 In some embodiments, the wiping part 41 extends along the first direction X, and the wiping member 40 is also provided with a plurality of connecting holes 44. The plurality of connecting holes 44 are arranged at intervals along the first direction X, and the sewage scraped off by the wiping part 41 enters the water collection tank 42 through the plurality of connecting holes 44.

[0119] For example, the connecting hole 44 is a strip-shaped hole along the second direction, which is perpendicular to the first direction X.

[0120] In other embodiments, a connecting hole 44 may also be provided on the wiper member 40, extending along the first direction X and located above the wiper portion 41, wherein the length of the connecting hole 44 is the same as or substantially the same as the length of the wiper portion 41. Alternatively, a third notch may also be provided on the wiper member 40, extending along the first direction X and located above the wiper portion 41, wherein the length of the third notch is the same as or substantially the same as the length of the wiper portion 41.

[0121] Please refer to Figure 9 The second aspect of this application provides a cleaning system 1000, which includes a cleaning base station 200 and a self-moving cleaning device 100 as described in the first aspect, wherein the cleaning base station 200 is used to dock the self-moving cleaning device 100.

[0122] For example, the cleaning base station 200 can charge the self-mobile cleaning device 100, fill and drain the liquid storage box 10 of the self-mobile cleaning device 100, and clean the mopping component 31 of the self-mobile cleaning device 100.

[0123] The cleaning system 1000 adopts any one or more embodiments of the self-moving cleaning device 100 described above, and thus has the beneficial effects of the above embodiments, which will not be described in detail here.
