[0038] It should be noted that the embodiments in the present application and the technical features in the embodiments can be combined with each other without conflict, and the detailed description in the specific embodiments should be understood as an explanation and illustration of the purpose of the present application, and should not be regarded as an improper limitation on the present application.

[0039] In the description of the embodiments of the present application, as shown in Figs. 4 and 6, the direction in which the arrow X is located is the “first direction”; as shown in Fig. 10, the direction in which the arrow Y is located is the “vertical direction”. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0040] The embodiments of the present application provide a water supply assembly 10 for a cleaning device.

[0041] In the process of cleaning an object to be cleaned, for example, in the process of cleaning a floor, water needs to be used to dilute and dissolve stains so as to better play a cleaning role.

[0042] Referring to Figs. 1 and 2, the water supply assembly 10 is used to supply water to devices in the cleaning device that need water, for example, to supply water to the cleaning assembly 30 and the like. The water supply assembly 10 comprises a water tank 11, a water pump 12 and a water path structure 13.

[0043] The water tank 11 is provided with a water storage space for storing water.

[0044] The water pump 12 is in communication with the water tank 11. In the working state, the water pump 12 pressurizes the water in the water storage space and outputs the water to the outside of the cleaning device.

[0045] It can be understood that the volume of the water storage space is limited. Therefore, the water in the water storage space needs to be supplemented by the water source outside the cleaning device.

[0046] The water tank 11 is provided with a drain port and an overflow port.

[0047] The overflow port is in communication with the water storage space and the outside of the water tank 11. During the process of filling water into the water storage space, the air in the water storage space can be discharged from the water storage space through the overflow port to maintain the air pressure balance in the water storage space, until the excess water is discharged from the overflow port to the outside of the water tank 11, so that the water can fill the water storage space, and the probability of water pressure increasing due to excessive water in the water storage space and causing damage to the water tank 11 is reduced.

[0048] The water pump 12 is provided with a water inlet and a water outlet.

[0049] The drain port is in communication with the water inlet, so that the water pump 12 pressurizes the water in the water tank 11 and discharges the water through the water outlet of the water pump 12 to meet the cleaning requirements of the cleaning device.

[0050] The water channel structure 13 is provided with an overflow channel 13a and a water supply channel 13b, the overflow channel 13a is provided with a first inlet 13g and a first outlet 13i, the water supply channel 13b is provided with a second inlet 13h and a second outlet 13j, the first inlet 13g is in communication with the overflow port, the second inlet 13h is in communication with the water outlet, the first outlet 13i is used to discharge the liquid in the overflow channel 13a, and the second outlet 13j is used to supply water to the cleaning assembly in the cleaning device.

[0051] The water channel structure is a rigid structure.

[0052] The water discharged from the overflow port enters the overflow channel 13a and is then discharged to the outside of the water channel structure 13. In this way, it is beneficial to reduce the residue of the water discharged from the overflow port in the cleaning device, reduce the problem of microbial breeding caused by accumulated water, and is beneficial to keep the inside of the cleaning device clean.

[0053] The water output from the water outlet of the water pump 12 enters the water supply channel 13b, and then the water supply channel 13b guides the water to other devices that need water in the cleaning device, such as the cleaning assembly.

[0054] The overflow channel 13a and the water supply channel 13b are not formed by a flexible structure of a hose, but are formed by a rigid structure.

[0055] The water supply assembly 10 in the embodiments of the present application has a water channel structure 13 which is not prone to deformation, and thus will not interfere with other devices in the cleaning device due to elastic deformation and the like, which is conducive to reducing assembly difficulty and improving assembly efficiency. In addition, the water channel structure 13 will not be reduced in cross section or even blocked due to bending, twisting and the like, which is conducive to reducing the failure rate of the water supply assembly 10.

[0056] In some embodiments, the overflow channel 13a and the water supply channel 13b are independent of each other, that is, the overflow channel 13a and the water supply channel 13b are not connected to each other. In this way, during water supply of the water pump 12 to the water supply channel 13b, water flow will not enter the overflow channel 13a and flow back to the water tank 11.

[0057] The connection mode between the first inlet 13g and the overflow port can be that the water channel structure 13 and the water tank 11 are embedded with each other to realize the connection therebetween, or a hose can be used to connect the two.

[0058] The connection mode between the second inlet 13h and the water outlet can be that the water channel structure 13 and the water pump 12 are embedded with each other to realize the connection therebetween, or a hose can be used to connect the two.

[0059] The first outlet 13i can be one or multiple, so as to reduce the possibility that foreign matters block the first outlet 13i after the cleaning device is used for a long time, and the overflow channel 13a can still discharge water.

[0060] In some embodiments, referring to FIG. 8, the overflow channel 13a includes a first overflow sub-channel 13c and multiple second overflow sub-channels 13d, the inlet of the first overflow sub-channel 13c forms the first inlet 13g, the outlet of the second overflow sub-channel 13d forms the first outlet 13i, each second overflow sub-channel 13d has the same connection position with the first overflow sub-channel 13c, and each second overflow sub-channel 13d has the same water flow path length.

[0061] After water flow enters the overflow channel 13a, the water flow first enters the first overflow sub-channel 13c and then is branched to each second overflow sub-channel 13d. Each second overflow sub-channel 13d has at least one outlet, that is, the first outlet 13i is multiple.

[0062] The second overflow sub-channel 13d is located downstream of the first overflow sub-channel 13c in the water flow direction.

[0063] The water flow path length of the second overflow sub-channel 13d refers to the length of the second overflow channel 13a from the connection position thereof with the first overflow sub-channel 13c to the first outlet 13i.

[0064] Thus, it is beneficial to make the water flow more evenly distributed to each second overflow sub-channel 13d after flowing out of the first overflow sub-channel 13c, so as to improve the utilization efficiency of the second overflow sub-channel 13d, and facilitate timely water discharge through the overflow channel 13a.

[0065] The plurality of second overflow sub-channels 13d means that the number of second overflow sub-channels 13d is not less than 2.

[0066] In some embodiments, referring to FIGS. 7-9, the second overflow sub-channels 13d are arranged on the side of the first overflow sub-channel 13c away from the water supply channel 13b.

[0067] Thus, it is beneficial to reduce the probability of interference between the arrangement of the second overflow sub-channels 13d and the water supply channel 13b, and improve the utilization efficiency of the space in the waterway structure 13.

[0068] The number of second outlets 13j can be one; it can also be multiple, so as to adapt to different sizes and numbers of water-using devices in the cleaning equipment, and facilitate more timely water supply.

[0069] In some embodiments, referring to FIG. 8, the water supply channel 13b includes a first water supply sub-channel 13e and a plurality of second water supply sub-channels 13f, the inlet of the first water supply sub-channel 13e forms the second inlet 13h, the outlet of the second water supply sub-channel 13f forms the second outlet 13j, each second water supply sub-channel 13f has the same communication position with the first water supply sub-channel 13e, and each second water supply sub-channel 13f has the same water flow path length.

[0070] After the water flow enters the water supply channel 13b, it first enters the first water supply sub-channel 13e, and then is distributed to each second water supply sub-channel 13f. Each second water supply sub-channel 13f has at least one outlet, that is, the second outlet 13j is multiple.

[0071] The second water supply sub-channel 13f is located downstream of the first water supply sub-channel 13e in the water flow direction.

[0072] The water flow path length of the second water supply sub-channel 13f refers to the length of the second water supply channel 13b from its communication position with the first water supply sub-channel 13e to the first outlet 13i.

[0073] Thus, it is beneficial to make the water flow more evenly distributed to each second overflow sub-channel 13d after flowing out of the first overflow sub-channel 13c, so as to improve the utilization efficiency of the second overflow sub-channel 13d, and facilitate timely water discharge through the overflow channel 13a.

[0074] The second water supply sub-paths 13f refer to the number of second water supply sub-paths 13f being not less than 2.

[0075] In some embodiments, referring to FIGS. 7-9, the second water supply sub-paths 13f are arranged on the side of the first water supply sub-paths 13e away from the overflow channel 13a.

[0076] In this way, the probability of interference between the arrangement of the second water supply sub-paths 13f and the overflow channel 13a is reduced, and the utilization efficiency of the space in the waterway structure 13 is improved.

[0077] In some embodiments provided with the first overflow sub-paths 13c, the second overflow sub-paths 13d, the first water supply sub-paths 13e, and the second water supply sub-paths 13f, referring to FIGS. 7 and 9, the first overflow sub-paths 13c are arranged in parallel with the first water supply sub-paths 13e, the second overflow sub-paths 13d are arranged on the side of the first overflow sub-paths 13c away from the first water supply sub-paths 13e, and the second water supply sub-paths 13f are arranged on the side of the first water supply sub-paths 13e away from the first overflow sub-paths 13c.

[0078] In this way, the probability of interference between the arrangement of the water supply channel 13b and the overflow channel 13a is reduced, and the utilization efficiency of the space in the waterway structure 13 is improved.

[0079] In some embodiments, the waterway structure 13 includes at least two housings 131, and each of the housings 131 is combined to form the overflow channel 13a and the water supply channel 13b.

[0080] In this way, the rigid structure is formed by the combination of the plurality of housings 131, and the waterway structure 13 is a non-integral structure, which is beneficial to reduce the manufacturing difficulty and facilitate subsequent disassembly and cleaning to prolong the service life of the waterway structure 13.

[0081] The specific connection manner between the housings 131 is not limited, such as adhesion, threaded connection by screw threads, ultrasonic welding, elastic buckle and card slot cooperation, etc.

[0082] The specific manner in which the plurality of housings 131 combine to form the water supply channel 13b and the overflow channel 13a is not limited.

[0083] For example, referring to FIGS. 3, 4 and 5, the housing 131 is provided with a plurality of water guide grooves 131a independent of each other, the water guide grooves 131a are open on one side along the first direction, the water guide grooves 131a of one of the housings 131 are combined along the first direction with the water guide grooves 131a of the other housing 131 to make the open positions of the water guide grooves 131a of the one housing 131 and the other housing 131 communicate along the first direction, at least one pair of the water guide grooves 131a that communicate with each other forms at least part of the water supply channel 13b, and at least another pair of the water guide grooves 131a that communicate with each other forms at least part of the overflow channel 13a.

[0084] The housing 131 has a plurality of water guide grooves 131a, a part of which is used to form the water supply passage 13b, and another part of which is used to form the overflow passage 13a.

[0085] One side of a housing 131 provided with the water guide groove 131a is covered along the first direction with the side of another housing 131 provided with the water guide groove 131a, so that the open position of the water guide groove 131a of one housing 131 is oppositely arranged and communicated with the open position of the water guide groove 131a of another housing 131 along the first direction, that is, the two housings 131 close the open positions of the water guide grooves 131a of each other along the first direction. After the two housings 131 are spliced, a plurality of passages formed by the pair of water guide grooves 131a are formed, a part of which forms at least part of the water supply passage 13b, and another part of which forms at least part of the overflow passage 13a.

[0086] In this way, it is beneficial to reduce the depth of a single water guide groove 131a along the first direction, facilitate the mold stripping along the first direction to form the water guide groove 131a in the process of injection molding the housing 131, and reduce the total size of the waterway structure 13 along the first direction under the condition that the size of each housing 131 along the first direction is substantially the same, so that the size of the waterway structure 13 is more compact.
