Detailed implementation manners

[0040] It should be noted that, without conflict, the embodiments in this application and the technical features in the embodiments can be combined with each other. The detailed description in the specific implementation manners should be understood as an explanatory illustration of the purpose of this application and should not be regarded as an improper limitation of this application.

[0041] In the description of the embodiments of the application, for the convenience of description, as Figure 4 and Figure 6 shown, the direction in which the arrow X is located is the "first direction"; as Figure 10 shown, 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, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application.

[0042] The embodiments of the present application provide a water supply assembly 10 for a cleaning device.

[0043] During the process of the cleaning device cleaning an object to be cleaned, for example, during the process of cleaning the floor, water is needed to dilute and dissolve stains in order to better play a cleaning role.

[0044] Referring to Figure 1 and Figure 2 , the water supply assembly 10 is used to supply water to the components in the cleaning device that need water, such as supplying water to the cleaning assembly 30 and the like. The water supply assembly 10 includes a water tank 11, a water pump 12, and a water path structure 13.

[0045] A water storage space is provided in the water tank 11 for storing water.

[0046] The water pump 12 is connected to the water tank 11. When the water pump 12 is in a working state, the water in the water storage space is pressurized and then output to the outside of the cleaning device.

[0047] It can be understood that the volume in the water storage space is limited. Therefore, the water in the water storage space needs to be replenished through a water source outside the cleaning device.

[0048] The water tank 11 is provided with a drain port and an overflow port.

[0049] The overflow port is connected to the water storage space and the outside of the water tank 11. During the process of injecting 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 drains out of the water tank 11 from the overflow port, enabling the water to fill the water storage space and also reducing the probability of the water pressure increasing due to excessive water in the water storage space and causing the water tank 11 to be damaged.

[0050] The water pump 12 is provided with an inlet and an outlet.

[0051] The drain port is connected to the inlet so that the water pump 12 can pump out the water in the water tank 11, pressurize it, and discharge it through the outlet of the water pump 12 to meet the cleaning requirements of the cleaning device.

[0052] The waterway 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, and the water supply channel 13b is provided with a second inlet 13h and a second outlet 13j. The first inlet 13g communicates with the overflow port, the second inlet 13h communicates 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 components in the cleaning device.

[0053] The waterway structure is a rigid structure.

[0054] The water discharged from the overflow port enters the overflow channel 13a and then is discharged outside the waterway 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 growth caused by water accumulation, and help maintain the cleanliness inside the cleaning device.

[0055] The water output from the water outlet of the water pump 12 enters the water supply channel 13b, and through the guiding action of the water supply channel 13b, the water is conveyed to other components in the cleaning device that require water, such as the cleaning components.

[0056] The overflow channel 13a and the water supply channel 13b are not formed by a flexible hose, but by a rigid structure.

[0057] In the water supply component 10 in the embodiment of the present application, the structure of the waterway structure 13 is not easily deformed, and there will be no situation where the hose forming the water flow channel in the related art interferes with other components in the cleaning device due to elastic deformation or the like, which is beneficial to reducing the assembly difficulty and improving the assembly efficiency; nor will there be problems such as the cross-section of the hose forming the water flow channel being reduced or blocked due to bending, twisting, etc. in the related art, which is beneficial to reducing the failure rate of the water supply component 10.

[0058] In some embodiments, the overflow channel 13a and the water supply channel 13b are independent of each other, that is to say, the overflow channel 13a and the water supply channel 13b do not communicate with each other. In this way, during the process of the water pump 12 supplying water to the water supply channel 13b, the water flow will not enter the overflow channel 13a and flow back into the water tank 11.

[0059] The connection method between the first inlet 13g and the overflow port can be that the waterway structure 13 and the water tank 11 are mutually embedded to achieve connection; or they can be connected by a hose.

[0060] The connection method between the second inlet 13h and the water outlet can be that the waterway structure 13 and the water pump 12 are mutually embedded to achieve connection; or they can be connected by a hose.

[0061] The number of the first outlet 13i can be one or more, so as to reduce the possibility of foreign matter blocking part of the first outlet 13i after the cleaning device is used for a long time, and the overflow channel 13a can still discharge water.

[0062] In some embodiments, see Figure 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 a first inlet 13g, and the outlet of the second overflow sub-channel 13d forms a first outlet 13i. The connection position of each second overflow sub-channel 13d is the same as that of the first overflow sub-channel 13c, and the water flow path length of each second overflow sub-channel 13d is equal.

[0063] After entering the overflow channel 13a, the water flows into the first overflow sub-channel 13c and then is divided into each second overflow sub-channel 13d. Each second overflow sub-channel 13d has at least one outlet, that is, there are multiple first outlets 13i.

[0064] The second overflow sub-channel 13d is located downstream of the first overflow sub-channel 13c along the water flow direction.

[0065] The water flow path length of the second overflow sub-channel 13d refers to the length of the second overflow channel 13a from the communication position with the first overflow sub-channel 13c to the first outlet 13i.

[0066] In this way, the water flowing out of the first overflow sub-channel 13c can be more evenly distributed to each second overflow sub-channel 13d, so as to improve the utilization efficiency of the second overflow sub-channel 13d and facilitate timely discharge of the water through the overflow channel 13a.

[0067] The plurality of second overflow sub-channels 13d refers to that the number of the second overflow sub-channels 13d is not less than two.

[0068] In some embodiments, see Figures 7 to 9 The second overflow sub-channel 13d is provided on a side of the first overflow sub-channel 13c away from the water supply channel 13b.

[0069] In this way, the probability of interference between the second overflow sub-channel 13 d and the water supply channel 13 b is reduced, and the utilization efficiency of the space in the water channel structure 13 is improved.

[0070] The number of the second outlets 13j can be one or more, so as to adapt to the different sizes and numbers of water-consuming devices in the cleaning equipment, thereby facilitating more timely water supply.

[0071] In some embodiments, see Figure 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 a second inlet 13h, and the outlet of the second water supply sub-channel 13f forms a second outlet 13j. The connection positions of the second water supply sub-channels 13f with the first water supply sub-channel 13e are the same, and the water flow path lengths of the second water supply sub-channels 13f are equal.

[0072] After the water flow enters the water supply channel 13b, it first enters the first water supply sub-channel 13e and then is diverted to each second water supply sub-channel 13f. Each second water supply sub-channel 13f has at least one outlet, that is to say, the second outlet 13j is plural.

[0073] The second water supply sub-channel 13f is located downstream of the first water supply sub-channel 13e in the water flow direction.

[0074] 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 connection position with the first water supply sub-channel 13e to the first outlet 13i.

[0075] In this way, it is beneficial to make the water flow more evenly diverted into each second water supply sub-channel 13f after flowing out of the first water supply sub-channel 13e, so that each water-requiring device in the cleaning device can obtain water supply more evenly, reducing the probability that some water-requiring devices in the cleaning device cannot work properly due to uneven water supply distribution, while some other parts have excessive water supply resulting in waste.

[0076] The plurality of second water supply sub-channels 13f means that the number of the second water supply sub-channels 13f is not less than 2.

[0077] In some embodiments, refer to Figures 7 to 9 , the second water supply sub-channel 13f is arranged on the side of the first water supply sub-channel 13e away from the overflow channel 13a.

[0078] In this way, it is beneficial to reduce the interference probability between the arrangement of the second water supply sub-channel 13f and the overflow channel 13a, and is beneficial to improve the utilization efficiency of the space inside the water channel structure 13.

[0079] In some embodiments provided with the first overflow sub-channel 13c, the second overflow sub-channel 13d, the first water supply sub-channel 13e and the second water supply sub-channel 13f, refer to Figure 7 and Figure 9 , the first overflow sub-channel 13c and the first water supply sub-channel 13e are arranged in parallel, the second overflow sub-channel 13d is located on the side of the first overflow sub-channel 13c away from the first water supply sub-channel 13e, and the second water supply sub-channel 13f is located on the side of the first water supply sub-channel 13e away from the first overflow sub-channel 13c.

[0080] In this way, it is beneficial to reduce the interference probability between the layout of the water supply channel 13b and the overflow channel 13a, and is beneficial to improve the utilization efficiency of the space inside the water channel structure 13.

[0081] In some embodiments, the water channel structure 13 includes at least two shells 131, and the shells 131 are joined together to enclose the overflow channel 13a and the water supply channel 13b.

[0082] In this way, a rigid structure is formed by joining multiple shells 131, and the water channel structure 13 is a non-integral structure, which is beneficial to reduce the manufacturing difficulty and is also convenient for subsequent disassembly and cleaning to extend the service life of the water channel structure 13.

[0083] The specific connection manner between the shells 131 is not limited, such as gluing, screw threading for threaded connection, ultrasonic welding, elastic snap and slot cooperation, etc.

[0084] The specific manner in which multiple shells 131 enclose to form the water supply channel 13b and the overflow channel 13a is not limited.

[0085] Exemplarily, referring to Figure 3 、 Figure 4 and Figure 5 , the shell 131 is provided with a plurality of independent water guide grooves 131a, one side of the water guide grooves 131a is open along the first direction, and two shells 131 are joined together along the first direction so that the open position of the water guide grooves 131a of one of them is communicated with the open position of the water guide grooves 131a of the other along the first direction. At least one pair of mutually communicated water guide grooves 131a form at least part of the water supply channel 13b, and at least another pair of mutually communicated water guide grooves 131a form at least part of the overflow channel 13a.

[0086] The shell 131 has a plurality of water guide grooves 131a, and a part of the water guide grooves 131a are used to form the water supply channel 13b, and another part of the water guide grooves 131a are used to form the overflow channel 13a.

[0087] One side of the shell 131 provided with the water guide grooves 131a is covered along the first direction with one side of another shell 131 provided with the water guide grooves 131a, so that the open position of the water guide grooves 131a of one shell 131 is arranged opposite to and communicated with the open position of the water guide grooves 131a of the other shell 131 along the first direction. That is to say, the two shells 131 close the open places of the water guide grooves 131a of each other along the first direction. After the two shells 131 are joined together, a plurality of paths formed by paired water guide grooves 131a are formed. A part of the paths form at least part of the water supply channel 13b, and another part of the paths form at least part of the overflow channel 13a.

[0088] In this way, it is beneficial to reduce the depth of a single water guide groove 131a along the first direction, making it easier to realize demolding along the first direction to form the water guide groove 131a during the injection molding process of the shell 131; it is beneficial to reduce the total size of the water channel structure 13 along the first direction when the sizes of each shell 131 along the first direction are roughly the same, making the size of the water channel structure 13 more compact.

[0089] The specific method for achieving water flow into the water guide groove 131a is not limited.

[0090] For example, see Figure 6 The shell 131 includes a first shell 132, the water guide trough 131a includes a first water trough 132a, and the first shell 132 is provided with at least two water inlet holes 132d. The water inlet holes 132d pass through the first shell 132 and are connected to the first water trough 132a. At least one water inlet hole 132d opens at one end away from the first water trough 132a to form a first inlet 13g, and at least another water inlet hole 132d opens at one end away from the first water trough 132a to form a second inlet 13h.

[0091] Water flowing out of the overflow or outlet enters the water inlet hole 132d and then flows into the first water tank 132a. A portion of the water inlet hole 132d and the first water tank 132a connected thereto form a portion of the overflow channel 13a, while another portion of the water inlet hole 132d and the first water tank 132a connected thereto form a portion of the water supply channel 13b.

[0092] In some embodiments, see Figure 6 The water inlet hole 132d penetrates the first shell 132 along the first direction and is located on a side away from the open position of the first water tank 132a.

[0093] The extension direction of the water inlet hole 132d is the same as the opening direction of the first water trough 132a, which is beneficial for forming the water inlet hole 132d and the first water trough 132a at one time by demolding along the first direction during the manufacturing process of the first shell 132, thereby simplifying the manufacturing process and improving production efficiency.

[0094] In some embodiments, see Figure 7 The first water tank 132a includes a first sub-water tank 132b and multiple second sub-water tanks 132c. The water inlet 132d is connected to the first sub-water tank 132b. The inlets of each second sub-water tank 132c are connected to the same position of the first sub-water tank 132b, and the dimensions of each second sub-water tank 132c in the extension direction are the same.

[0095] The extending direction of the second sub-water tank 132 c refers to the flowing direction of water in the second sub-water tank 132 c.

[0096] The first sub-water channel 132b is used to form a first overflow sub-channel 13c or a first water supply sub-channel 13e.

[0097] The second sub-water troughs 132c are used to form the second overflow sub-channels 13d or the second water supply sub-channels 13f. The dimensions of the second sub-water troughs 132c in the extension direction are the same, so that the water flow path lengths of the second overflow sub-channels 13d are equal or the water flow path lengths of the second water supply sub-channels 13f are equal.

[0098] In some embodiments, see Figure 6 , one end of the second sub-water tank 132c away from the connection position with the first sub-water tank 132b along its extension direction is a closed end, that is, the water guide groove 131a of the other shell 131 configured in pair with the second sub-water tank 132c is connected to the outside of the cleaning device; in other embodiments, one end of the second sub-water tank 132c away from the connection position with the first sub-water tank 132b along its extension direction is connected to the outside of the cleaning device.

[0099] It is understandable that the opening of the water inlet hole 132d away from the end of the first water tank 132a forms the first inlet 13g or the second inlet 13h.

[0100] In some embodiments, the first housing 132 is provided with a mounting post, which extends along a first direction and is located on a side of the first housing 132 that is away from the first water tank 132a along the first direction. At least a portion of the water inlet 132d extends through the mounting post along the first direction. The mounting post can be embedded in a hose so that a passage in the hose connects the water inlet 132d to the overflow or outlet.

[0101] The specific method for achieving water flowing out of the water guide groove 131a is not limited.

[0102] In some embodiments, see Figure 8 and Figure 9 The shell 131 includes a second shell 133, the water guide trough 131a includes a second water trough 133a, and the second shell 133 is provided with at least two water outlet holes 133d, the water outlet holes 133d pass through the second shell 133, and the water outlet holes 133d are connected to the second water trough 133a. At least one water outlet hole 133d opens at one end away from the second water trough 133a to form a first outlet 13i, and at least another water outlet hole 133d opens at one end away from the second water trough 133a to form a second outlet 13j.

[0103] A portion of the water outlet holes 133d and the second water tank 133a communicating therewith form a portion of the overflow channel 13a, and another portion of the water outlet holes 133d and the second water tank 133a communicating therewith form a portion of the water supply channel 13b.

[0104] In some embodiments, the water outlet 133 d penetrates the second housing 133 along the first direction and is located on a side away from the open position of the second water tank 133 a .

[0105] The extension direction of the water outlet 133d is the same as the opening direction of the second water tank 133a, which is beneficial for forming the water outlet 133d and the second water tank 133a at one time by demolding along the first direction during the manufacturing process of the second shell 133, thereby simplifying the manufacturing process and improving production efficiency.

[0106] In some embodiments, see Figure 8 The second water tank 133a includes a third sub-water tank 133b and multiple fourth sub-water tanks 133c. The water outlet 133d is connected to the fourth sub-water tank 133c. The inlet of each fourth sub-water tank 133c is connected to the same position of the third sub-water tank 133b, and the dimensions of each fourth sub-water tank 133c in the extension direction are the same.

[0107] The extending direction of the fourth sub-water tank 133 c refers to the flowing direction of water in the fourth sub-water tank 133 c.

[0108] The third sub-water tank 133b is used to form the first overflow sub-channel 13c or the first water supply sub-channel 13e.

[0109] The fourth sub-water troughs 133c are used to form the second overflow sub-channels 13d or the second water supply sub-channels 13f. The dimensions of the fourth sub-water troughs 133c in the extension direction are the same, so that the water flow path lengths of the second overflow sub-channels 13d are equal or the water flow path lengths of the second water supply sub-channels 13f are equal.

[0110] It can be understood that the water in the water guide groove 131 a of the other shell 131 configured in pair with the second water groove 133 a flows into the second water groove 133 a .

[0111] It is understandable that the opening of the water outlet 133d away from the end of the second water tank 133a forms the first outlet 13i or the second outlet 13j.

[0112] It is understood that in some embodiments, referring to Figure 5 、 Figure 6 and Figure 8 A part of the second water trough 133a, the water outlet hole 133d connected thereto, the first water trough 132a connected thereto along the first direction, and the water inlet hole 132d connected thereto form an overflow channel 13a; another part of the second water trough 133a, the water outlet hole 133d connected thereto, the first water trough 132a connected thereto along the first direction, and the water inlet hole 132d connected thereto form a water supply channel 13b.

[0113] In some embodiments, seeFigure 5 , the water supply channel 13b and the overflow channel 13a are arranged side by side perpendicular to the first direction to reduce the dimension of the water channel structure 13 in the first direction.
