[0049] To address the issue of wastewater spillage when existing cleaning equipment 00 collects wastewater through the wastewater box 41, the inventors of this utility model, after analyzing and verifying the assembly structure between the roller 21 and the squeegee of the cleaning equipment 00, as well as the structure of the wastewater box 41, discovered that a water collection trough is typically provided on the side of the wastewater box 41 near the squeegee, with the drain outlet of the squeegee opposite to the water collection trough. Wastewater scraped off by the squeegee falls directly from the drain outlet into the water collection trough under gravity. When the wastewater box 41 also has a cavity communicating with the water collection trough, the wastewater in the collection trough will flow into the cavity for temporary storage. With this structure, when the cleaning equipment 00 is subjected to a large impact or is lifted and shaken, the wastewater from the drain outlet and the wastewater in the water collection trough are easily spilled onto the ground, causing secondary pollution. Therefore, the first embodiment of this utility model provides a cleaning mechanism; please refer to [link to relevant documentation]. Figures 1 to 8 The cleaning facility includes cleaning components and wastewater collection components 40.

[0050] like Figure 1 and Figure 2 As shown, the cleaning assembly includes a bracket 10, a cleaning component 20, and a squeegee component 30. Figure 3 As shown, the cleaning component 20 includes a roller 21 and a flexible cleaning element 22. The flexible cleaning element 22 can be a mop made of flexible fibers or a sponge-like structure with absorbent properties. The roller 21 is connected to the support 10 and can rotate relative to the support 10 around its own axis. The flexible cleaning element 22 is laid on the surface of the roller 21 so that it can rotate and clean the surface to be cleaned under the drive of the roller 21. The cleaning component 20 may also include a drive mechanism, which is mounted on the support 10 and sleeved inside the roller 21. The drive mechanism may include a motor and a connector. The connector is connected to the output shaft of the motor and engages with the inner wall of the roller 21. Thus, starting the motor drives the connector to rotate the roller 21.

[0051] The wiping component 30 is connected to the bracket 10 and abuts against the flexible cleaning component 22. Thus, as the flexible cleaning component 22 rotates with the roller 21, the wastewater and solid waste on the flexible cleaning component 22 can be scraped off the flexible cleaning component 22. The wiping component 30 is provided with a drain outlet 311, and the wastewater scraped off from the flexible cleaning component 22 by the wiping component 30 flows to the drain outlet 311.

[0052] The wastewater collection assembly 40 includes a wastewater box 41 and a pipe component 42. The wastewater box 41 has a liquid storage chamber, which is a closed cavity structure. The pipe component 42 is installed between the wastewater box 41 and the scraper component 30 and connects the drain outlet 311 and the liquid storage chamber. Thus, wastewater flowing to the drain outlet 311 can be transferred to the liquid storage chamber through the pipe component 42, instead of falling into the wastewater box 41 by gravity, achieving fully sealed collection of wastewater.

[0053] As can be seen, in this embodiment, the cleaning mechanism includes a cleaning component and a wastewater collection component 40. The cleaning component's scraper 30 has a drain outlet 311, through which wastewater scraped from the flexible cleaning component 22 flows. The wastewater collection component 40's pipe component 42 is installed between the wastewater box 41 and the scraper 30, connecting the drain outlet 311 and the storage chamber within the wastewater box 41. Thus, after the wastewater scraped by the scraper 30 flows to the drain outlet 311, it can be directly transported to the storage chamber of the wastewater box 41 via the pipe component 42, achieving closed collection of wastewater from the cleaning component 20. Therefore, during the cleaning process using this cleaning mechanism, even if the cleaning equipment 00 is subjected to collisions and / or shaking and / or is manually lifted and / or moved to the reverse side, wastewater will not leak from the wastewater box 41 or spill out before entering the wastewater box 41, improving the user experience.

[0054] The squeegee component 30 in this embodiment includes a mounting body 31 and a filter element 32. The mounting body 31 is connected to the bracket 10, and a drain outlet 311 is disposed on the mounting body 31. The pipe component 42 is connected to the mounting body 31 and communicates with the drain outlet 311. The filter element 32 is disposed on the side of the drain outlet 311 facing away from the pipe component 42, and the filter element 32 abuts against the flexible cleaning component 22. The filter element 32 is used to filter the scraped wastewater and discharge it to the drain outlet 311. Thus, before the wastewater in the drain outlet 311 enters the pipe component 42, since the wastewater in the drain outlet 311 is filtered by the filter element 32 before being discharged, there is no large solid waste in the wastewater, thereby avoiding the pipe component 42 being blocked by solid waste during the process of conveying wastewater. Therefore, the user can avoid frequently unclogging the pipe component 42.

[0055] In some implementations, such as Figure 2 and Figure 5 As shown, the pipe component 42 includes a connecting part 421 and a pipe section 422. A flow guiding channel 211 is provided within the connecting part 421. A plug-in structure 50 is provided between the connecting part 421 and the wiper component 30. The plug-in structure 50 can be specifically located between the connecting part 421 and the mounting body 31 of the wiper component 30. The connecting part 421 is connected to the mounting body 31 via the plug-in structure 50, and the flow guiding channel 211 communicates with the drain outlet 311. The pipe section 422 is connected to the connecting part 421 and communicates with the flow guiding channel 211. The pipe section 422 and the connecting part 421 can be separately or integrally arranged. When integrally arranged, the assembly steps of the cleaning mechanism can be reduced, thereby improving assembly efficiency. In this embodiment, the connecting part 421 is connected to the mounting body 31 of the wiper component 30 via the plug-in structure 50, which reduces assembly difficulty and ensures the sealing of sewage entering the pipe section 422 from the drain outlet 311 along the flow guiding channel 211, preventing sewage leakage.

[0056] like Figure 5As shown, the insertion structure 50 includes an insertion groove 51 and an insertion protrusion 52. The insertion groove 51 is located on the side of the connecting portion 421 near the mounting body 31 of the wiper component 30 and communicates with the flow channel 211. Specifically, a first opening 511 is provided on the side of the insertion groove 51 away from the mounting body 31 of the wiper component 30, and the first opening 511 communicates with the flow channel 211. The insertion protrusion 52 is located on the side of the wiper component 30, or the mounting body 31 of the wiper component 30, near the connecting portion 421. The insertion protrusion 52 is adapted to the insertion groove 51 and is at least partially inserted into the insertion groove 51. The drain outlet 311 is located in the insertion protrusion 52. Thus, in this embodiment, by at least partially inserting the insertion protrusion 52 into the insertion groove 51, the connecting portion 421 and the wiper component 30 can be connected together, making assembly efficient and convenient. At this time, the sewage coming out of the drain outlet 311 will flow sequentially along the second guide channel 211 and the first opening 511 into the pipe section 422, and then be transmitted to the sewage box 41 through the pipe section 422. Of course, in some optional embodiments, the insertion groove 51 can also be set on the side of the mounting body 31 near the connecting part 421, and the insertion protrusion 52 can be set on the side of the connecting part 421 near the mounting body 31. In this regard, as long as the connecting part 421 and the mounting body 31 can be inserted together by the insertion structure 50, the specific setting of the insertion structure 50 is not limited to this embodiment.

[0057] In some embodiments, the filter element 32 and the mounting body 31 enclose a liquid storage space 301, and the drain outlet 311 communicates with the liquid storage space 301. Water filtered by the filter element 32 first enters the liquid storage space 301, then flows from the liquid storage space 301 along the drain outlet 311 into the pipe component 42, and is subsequently guided through the pipe component 42 to the wastewater box 41. The liquid storage space 301 can temporarily store a large amount of filtered wastewater, thereby reducing the drainage pressure at the drain outlet 311. Simultaneously, when a negative pressure suction component 60 is subsequently connected to the liquid storage chamber to perform a negative pressure suction operation, so that the air pressure in the liquid storage chamber is lower than the air pressure at the drain outlet 311, the presence of the liquid storage space 301 can also improve the negative pressure suction efficiency of the negative pressure suction component 60, achieving a lower air pressure in the liquid storage chamber than at the drain outlet 311 more quickly.

[0058] A first groove 312 is provided on the side of the mounting body 31 near the filter element 32. The filter element 32 includes a plate 321 and filter holes 322 disposed on the plate 321. The side of the plate 321 near the mounting body 31 is at least partially embedded in the first groove 312 and forms a liquid storage space 301 with the inner wall of the first groove 312. The drain outlet 311 communicates with the liquid storage space 301. Along the radial direction of the roller 21, the side of the plate 321 near the roller 21 is at least partially located outside the first groove 312 and abuts against the flexible cleaning element 22, so that the plate 321 can scrape off sewage and solid waste on the flexible cleaning element 22. In some embodiments, a second groove 3211 may be provided on the side of the plate 321 away from the drain outlet 311. Thereby, the plate 321 can scrape sewage and solid waste on the flexible cleaning element 22 into the second groove 3211, so that solid waste accumulates in the second groove 3211, thereby increasing the collection capacity of the plate 321 for solid waste. Multiple filter holes 322 are distributed on the plate 321 and extend to the side of the plate 321 near the liquid storage space 301. Specifically, they can be distributed in the second groove 3211 along the circumference of the roller 21 near the bottom of the liquid storage space 301. Wastewater in the second groove 3211 will flow into the liquid storage space 301 through the filter holes 322, while solid waste will remain in the second groove 3211. The solid waste in the second groove 3211 can be cleaned periodically. The overall structure of the filter element 32 is simple to design and easy to assemble with the mounting body 31, improving the assembly efficiency of the cleaning components. Along the axial direction of the roller 21, the projected outline of the second groove 3211 near the bottom of the liquid storage space 301 is arc-shaped. The arc-shaped second groove 3211 reduces the flow resistance of wastewater and can store more solid waste.

[0059] The length of the plate 321 extends along the axial direction of the roller 21 to ensure that sewage and debris from all parts of the flexible cleaning component 22 along the axial direction of the roller 21 can be scraped into the second groove 3211 by the plate 321. Furthermore, multiple filter holes 322 are arranged in at least one row along the length of the roller 21, such as one, two, three, or four rows, to simultaneously filter sewage through at least one row of multiple filter holes 322, thereby improving the filtration efficiency of the sewage.

[0060] In the mounting body 31, a first guide slope 121 and a second guide slope 122 are provided near the bottom of the first groove 312 close to the roller 21. Along the axial direction of the roller 21, the first guide slope 121 and the second guide slope 122 are located on opposite sides of the drain outlet 311, and the horizontal plane of the side of the first guide slope 121 and the second guide slope 122 closer to the drain outlet 311 is lower than the horizontal plane of the side farther from the drain outlet 311. As a result, the wastewater scraped off by the plate 321 will be quickly guided to the drain outlet 311 along the first guide slope 121 and the second guide slope 122, and then conveyed into the pipe component 42 along the drain outlet 311. This also prevents the wastewater scraped off by the plate 321 from the opposite ends of the flexible cleaning member 22 from overflowing from the gaps due to prolonged residence time.

[0061] In this embodiment, the horizontal plane of the pipe component 42 is higher than the horizontal plane of the storage chamber of the sewage box 41, allowing sewage to flow along the pipe component 42 into the storage chamber under the action of gravity. Alternatively, a siphon effect can be used to guide sewage through the pipe component 42 into the storage chamber. A siphon effect is a fluid dynamics phenomenon that allows liquid to flow from the drain outlet 311 through the pipe component 42 to the lower-positioned storage chamber of the sewage box 41 without an external pump. To improve the efficiency and reliability of sewage collection, the sewage collection assembly 40 in this embodiment also includes a negative pressure extraction component 60. The negative pressure extraction component 60 is connected to the storage chamber to perform a negative pressure extraction operation, so that the air pressure in the storage chamber is lower than the air pressure at the drain outlet 311. Therefore, during the sewage collection process, the negative pressure component 60 is used to extract the air pressure in the storage chamber to a level lower than that of the drain outlet 311, which ensures that the sewage flowing to the drain outlet 311 can flow into the storage chamber efficiently and quickly, and reduces the installation difficulty of the sewage box 41 and the cleaning components in the cleaning equipment 00.

[0062] like Figure 1As shown, the negative pressure extraction component 60 includes a vacuum pump 61, a first connecting pipe 62, and a second connecting pipe 63. The vacuum pump 61 includes an extraction port 611 and an exhaust port 612. The first connecting pipe 62 connects the extraction port 611 and the liquid storage chamber, so that when the vacuum pump 61 is started, it can extract the gas in the liquid storage chamber, making the gas pressure in the liquid storage chamber lower than the gas pressure at the drain port 311. During the operation of the vacuum pump 61, a surge phenomenon may occur, causing liquid in the liquid storage chamber to flow along the first connecting pipe 62 to the vacuum pump 61. To address this, this embodiment connects the second connecting pipe 63 between the exhaust port 612 and the drain port 311, so that the second connecting pipe 63 can directly discharge the small amount of sewage extracted due to the surge phenomenon into the drain port 311 (or directly into the liquid storage space 301). This sewage will then be transported back to the liquid storage chamber along the pipe component 42, realizing closed-loop sewage recycling, with no risk of leakage or spillage throughout the recycling process. At this point, a connecting port can be provided on the mounting body 31 to communicate with the drain outlet 311 or the liquid storage space 301, and then the end of the second connecting pipe 63 away from the exhaust port 612 can be connected to the connecting port. Of course, in this embodiment, the end of the second connecting pipe 63 away from the exhaust port 612 can also be aligned with the flexible cleaning component 22. For example, a corresponding through hole can be provided on the bracket 10 to lay the second connecting pipe 63 opposite to the flexible cleaning component 22, so that the sewage discharged from the second connecting pipe 63 can be directly sprayed onto the flexible cleaning component 22 and then scraped into the drain outlet 311 by the scraper component 30. At this point, the end of the second connecting pipe 63 away from the exhaust port 612 can be specifically located on the side of the plate 321 away from the drain outlet 311.

[0063] like Figure 1 and Figure 8 As shown, the cleaning mechanism in this embodiment also includes a connecting component 70, which is provided with a first insertion pipe 71, a second insertion pipe 72, a third insertion pipe 73, and a fourth insertion pipe 74. The first insertion pipe 71 and the second insertion pipe 72 are interconnected, and the third insertion pipe 73 and the fourth insertion pipe 74 are interconnected. Specifically, the first connecting pipe 62 is connected to the first insertion pipe 71, and the pipe component 42 is connected to the third insertion pipe 73. Both the second insertion pipe 72 and the fourth insertion pipe 74 are at least partially inserted into the liquid storage chamber to communicate with it. Therefore, in this embodiment, the connecting component 70 can be installed first on the side of the wastewater box 41 near the cleaning component 20, and the second insertion pipe 72 and the fourth insertion pipe 74 can be connected to the liquid storage chamber before connecting the first connecting pipe 62 to the first insertion pipe 71, and the pipe section 422 of the pipe component 42 is connected to the third insertion pipe 73. This simple and convenient installation improves the assembly efficiency of the cleaning mechanism.

[0064] Along the height of the wastewater box 41, the second connector 72 is located at the top of the wastewater box 41. This ensures that during the process of vacuum pump 61 drawing negative pressure through the first connecting pipe 62 connected to the second connector 72, excessive wastewater is prevented from entering the vacuum pump 61 along the first connecting pipe 62, thus improving the reliability of the wastewater collection process. The fourth connector 74 is located between the second connector 72 and the bottom of the storage chamber. Therefore, after a negative pressure environment is generated in the storage chamber, wastewater in the pipe component 42 can enter the storage chamber along the fourth connector 74.

[0065] As can be seen, in this embodiment, the sewage box 41 is directly connected to the storage chamber inside the sewage box 41 through the set closed pipeline component. After the sewage box 41 is drawn to a negative pressure environment by the vacuum pump 61, the sewage scraped by the scraper component 30 is directly transferred to the storage chamber through the pipeline component 42. This can prevent sewage from splashing out when the cleaning equipment 00 is moved over for cleaning or when the cleaning equipment 00 is subjected to a large collision or impact.

[0066] A second embodiment of this utility model also provides a cleaning device 00, which includes a cleaning mechanism. For example... Figure 9 As shown, the cleaning device 00 also includes a base 01, with a receiving cavity 011 at its bottom. The cleaning component is mounted in the receiving cavity 011 via its bracket 10. Along the forward direction of the cleaning device 00, the wastewater box 41 can be specifically installed behind the cleaning component. The vacuum pump 61 of the cleaning mechanism can be mounted on the base 01 or on the bracket 10; this embodiment does not impose a single limitation on this. When the vacuum pump 61 is mounted on the base 01, a corresponding through hole can be provided on the base 01 to lay the first connecting pipe 62 to the connecting member 70 and connect it to the first insertion pipe 71 of the connecting member 70. For other specific structures of the cleaning mechanism, please refer to the content provided in the first embodiment of this utility model; this embodiment will not repeat them here.

[0067] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0068] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components.
