[0063] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent like or similar structures, and thus their detailed description will be omitted.

[0064] Although relative terms such as "upper" and "lower" are used in this specification to describe the relationship of one illustrated component to another, these terms are used herein for convenience only, such as in accordance with the orientation of the illustrations in the accompanying drawings. It will be understood that if the illustrated device were flipped upside down, the component described as "upper" would become the component "lower." When a structure is referred to as "on" another structure, this may mean that the structure is integrally formed with the other structure, that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure via the other structure.

[0065] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express open-ended inclusion and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first" and "second" etc. are used only as labels and are not intended to limit the quantity of their objects.

[0066] As shown in FIG. 1 to FIG. 10 , the present disclosure first provides a sewage suction component, which has a good sewage suction effect and does not leave sewage and solid waste remaining or deposited in the pipeline.

[0067] The sewage suction assembly provided by the present disclosure may include: a sewage suction bucket 1, a front housing 2, a sewage suction pipe 3, and a linkage mechanism 4. The sewage suction bucket 1 may include a first accommodating chamber 11; the front housing 2 may include a second accommodating chamber 21 and a first opening 22; the sewage suction pipe 3 may be in communication with the first accommodating chamber 11, with at least a portion of the sewage suction pipe 3 disposed within the second accommodating chamber 21; and the first opening 22 may expose at least a portion of the end of the sewage suction pipe 3 away from the sewage suction bucket 1.

[0068] The linkage mechanism 4 may include a first mounting portion 41 and a trigger portion 42. The first mounting portion 41 may be connected to the sewage suction pipe 3. The trigger portion 42 may have a first state and a second state. When the trigger portion 42 is in the first state, the end of the sewage suction pipe 3 away from the sewage suction bucket 1 is in a first position; when the trigger portion 42 is in the second state, the end of the sewage suction pipe 3 away from the sewage suction bucket 1 is in a second position, and in the extension direction of the sewage suction pipe 3, the second position is away from the sewage suction bucket 1 relative to the first position.

[0069] Thus, when it is necessary to divert the sewage and solid waste in the cleaning host into the sewage bucket, the trigger device can be placed in the second state, so that the end of the sewage suction pipe 3 away from the sewage suction bucket 1 is closer to the cleaning host, making it convenient to connect the end of the sewage suction pipe 3 away from the sewage suction bucket 1 with the cleaning host through the first opening 22; when the sewage suction is completed, the sewage suction pipe 3 can be separated from the cleaning host, and the end of the sewage suction pipe 3 away from the sewage suction bucket 1 can be restored to the first position to be retracted into the second accommodating chamber 21, so as to reduce the probability of damage to the sewage suction pipe 3, thereby effectively improving the service life of the sewage suction component.

[0070] Furthermore, as can be seen from the above, the pipeline in the sewage suction assembly provided by the present disclosure has only one sewage suction pipe 3, so the pipeline in the sewage suction assembly provided by the present disclosure is not spliced ​​together by multiple sections of pipelines, which can avoid the appearance of interfaces in the pipeline, and can also prevent sewage and solid waste from remaining at the interfaces, effectively avoiding the problem of odor or clogging the pipeline, thereby improving the sewage suction effect of the sewage suction assembly. At the same time, such a configuration also improves the sealing of the sewage suction pipe 3, avoiding the problem of interfaces in the pipeline and water leakage at the interfaces, thereby further improving the sewage suction effect of the sewage suction assembly.

[0071] It should be noted that the cleaning host mentioned above can be a cleaning device that needs to clean sewage and / or solid waste, such as a floor scrubber, a sweeping robot, or a vacuum cleaner. In addition, the end of the sewage suction pipe 3 away from the sewage suction bucket 1 mentioned above refers to the end of the sewage suction pipe 3 away from the sewage suction bucket 1 in its own extension direction.

[0072] In one embodiment of the present disclosure, as shown in Figures 1 to 4, the sewage suction bucket 1 may have a sewage suction pipe port 12, which may be connected to the first accommodating chamber 11, and the sewage suction pipe 3 may be connected to the first accommodating chamber 11 through the sewage suction pipe port 12.

[0073] In one embodiment, part of the sewage suction pipe 3 can be located in the first accommodating chamber 11. This arrangement ensures that sewage or solid waste can be completely diverted into the first accommodating chamber 11 through the sewage suction pipe 3, preventing sewage or solid waste from leaking out of the sewage suction barrel 1 from the connection between the sewage suction pipe 3 and the first accommodating chamber 11. This can also prevent the leaked sewage and solid waste from causing secondary pollution to the environment, further improving the sewage suction effect of the sewage suction assembly.

[0074] In this embodiment, part of the sewage suction pipe 3 can extend into the first accommodating cavity 11 through the sewage suction pipe opening 12. The cross-sectional shape of the sewage suction pipe opening 12 can be the same as that of the sewage suction pipe 3. This configuration facilitates the insertion of the sewage suction pipe 3 into the first accommodating cavity 11 and minimizes the gap between the outer circumference of the sewage suction pipe 3 and the sidewall of the sewage suction pipe opening 12, thereby improving the sealing between the sewage suction pipe 3 and the sewage suction pipe opening 12.

[0075] In one embodiment, the sewage suction bucket 1 can be disposed opposite the front shell 2, and the first opening 22 can be disposed on a side of the front shell 2 opposite the sewage suction bucket 1. The sewage suction pipe opening 12 can also be disposed on a side of the sewage suction bucket 1 opposite the front shell 2. This arrangement allows the sewage suction pipe 3 located outside the first accommodating chamber 11 to reach the sewage suction pipe opening 12 without bending. Thus, the sewage suction pipe 3 located outside the first accommodating chamber 11 can be configured as a straight pipe, thereby reducing the number of bends in the sewage suction pipe 3 and preventing sewage and solid waste from remaining or accumulating in the bends, thereby causing odor or clogging the pipe.

[0076] In one embodiment, the sewage suction bucket 1 may include a barrel body 13 and a barrel cover 14. The first accommodating chamber 11 may be located within the barrel body 13, and the barrel cover 14 may seal the first accommodating chamber 11 to block odors emitted by the sewage and solid waste located within the first accommodating chamber 11. Furthermore, the present disclosure provides the sewage suction bucket 1 with a split structure consisting of the barrel body 13 and the barrel cover 14, which facilitates the cleaning of sewage and solid waste within the sewage suction bucket 1.

[0077] In this embodiment, the sewage suction pipe opening 12 can be provided on the barrel body 13, and can be provided on a side of the barrel body 13 opposite to the front shell 2. Compared with the method of providing the sewage suction pipe opening 12 on the barrel cover 14, providing the sewage suction pipe opening 12 on the barrel body 13 can prevent the sewage suction pipe 3 from interfering with the opening and closing of the barrel cover 14, thereby facilitating the cleaning of sewage and solid waste in the sewage suction barrel 1, and preventing the sewage suction pipe 3 from being damaged when the barrel cover 14 is opened and closed.

[0078] In one embodiment of the present disclosure, as shown in Figures 1 to 5 and 9 , the sewage suction assembly may further include a telescopic member 5. The telescopic member 5 may include a first connecting portion 51, a telescopic portion 52, and a second connecting portion 53. The first connecting portion 51 may be connected to the sewage suction pipe 3, the second connecting portion 53 may be connected to the sewage suction pipe 3, and the telescopic portion 52 may be located between the first connecting portion 51 and the second connecting portion 53. Furthermore, when the trigger portion 42 is in the second state, the telescopic portion 52 may have a restoring force. It can be understood that when the telescopic member 5 is arranged outside the sewage suction bucket 1, when the trigger part 42 is in the second state, the first connection part 51 can follow the sewage suction pipe 3 to move in the direction away from the second connection part 53, and the telescopic part 52 will be in a stretched state, so that the telescopic part 52 has a retracting restoring force; when the telescopic member 5 is arranged inside the sewage suction bucket 1, when the trigger part 42 is in the second state, the first connection part 51 can follow the sewage suction pipe 3 to move in the direction close to the second connection part 53, and the telescopic part 52 will be in a compressed state, so that the telescopic part 52 has a rebound restoring force.

[0079] Therefore, the present disclosure provides a telescopic member 5. When the sewage suction work is completed and the sewage suction pipe 3 is separated from the cleaning main body, the restoring force of the telescopic member 5 can be used to drive the sewage suction pipe 3 to retract, so that the end of the sewage suction pipe 3 away from the sewage suction bucket 1 is retracted from the second position to the first position. In addition, since the restoring force of the telescopic member 5 is relatively large, the provision of the telescopic member 5 can ensure that the sewage suction pipe 3 can be retracted into place.

[0080] In one embodiment, the telescopic portion 52 can be sleeved over at least a portion of the outer circumference of the sewage suction pipe 3. It is understood that when the telescopic member 5 is disposed outside the sewage suction bucket 1, the telescopic portion 52 can be sleeved over at least a portion of the outer circumference of the sewage suction pipe 3 located outside the sewage suction bucket 1; when the telescopic member 5 is disposed within the first accommodating cavity 11, the telescopic portion 52 can be sleeved over at least a portion of the outer circumference of the sewage suction pipe 3 located within the first accommodating cavity 11.

[0081] The sewage suction pipe 3 may include a main body 31 and a fixing portion 32. The fixing portion 32 may be disposed on the outer circumference of the main body 31 and may extend away from the main body 31. The first connecting portion 51 may be connected to the fixing portion 32. This arrangement provides a more stable connection position for the first connecting portion 51. Furthermore, this arrangement avoids the possibility of a loose seal at the connection caused by directly connecting the first connecting portion 51 to the main body 31, thereby preventing pressure relief and water leakage at the connection.

[0082] It should be noted that when the telescopic member 5 is located outside the sewage suction bucket 1 , the fixing portion 32 is also located outside the sewage suction bucket 1 ; when the telescopic member 5 is located inside the sewage suction bucket 1 , the fixing portion 32 is also located inside the sewage suction bucket 1 .

[0083] In one embodiment, the sewage suction pipe 3 can be an integrated structure, that is, the main body 31 and the fixing portion 32 can be manufactured through an integrated molding process, without the need to connect the main body 31 and the fixing portion 32 using bonding, welding, or other connection methods. This configuration can improve the production efficiency of the sewage suction pipe 3, facilitate mass production of the sewage suction pipe 3, and also reduce the number of connection points within the sewage suction pipe 3, thereby increasing the service life of the sewage suction pipe 3.

[0084] However, the present invention is not limited thereto. The sewage suction pipe 3 may also be a split structure, that is, the main body 31 and the fixing portion 32 may be manufactured separately, and the components may be connected by bonding, welding or other connection methods to form the sewage suction pipe 3 .

[0085] In one embodiment, the first connection portion 51 may extend in a direction close to the outer circumferential surface of the main body portion 31 , and an extending surface of the first connection portion 51 is connected to an extending surface of the fixing portion 32 .

[0086] It should be noted that the extended surfaces of the first connecting portion 51 may be the two surfaces of the first connecting portion 51 in the first direction X, and the extended surfaces of the fixing portion 32 may be the two surfaces of the fixing portion 32 in the first direction X. The first direction X may be the direction from the sewage suction bucket 1 toward the front shell 2. The extended surface of the first connecting portion 51 near the front shell 2 may be connected to the extended surface of the fixing portion 32 facing away from the front shell 2; alternatively, the extended surface of the first connecting portion 51 facing away from the front shell 2 may be connected to the extended surface of the fixing portion 32 near the front shell 2.

[0087] Since the areas of the extension surface of the first connection part 51 and the extension surface of the fixing part 32 are large, when an extension surface of the first connection part 51 is connected to an extension surface of the fixing part 32, the connection area between the first connection part 51 and the fixing part 32 can be increased, thereby improving the connection stability between the first connection part 51 and the fixing part 32.

[0088] The fixing portion 32 and the first connecting portion 51 can both be annular structures disposed around the outer circumference of the main body portion 31. This arrangement can further increase the connection area between the fixing portion 32 and the first connecting portion 51, further improving the stability of the connection between the fixing portion 32 and the first connecting portion 51. Furthermore, when an extended surface of the first connecting portion 51 is connected to an extended surface of the fixing portion 32, a good seal can be achieved between the first connecting portion 51 and the fixing portion 32, preventing pressure relief or water leakage at the connection between the first connecting portion 51 and the fixing portion 32.

[0089] In this embodiment, when the telescopic member 5 is disposed outside the sewage suction bucket 1, the first connecting portion 51 can be disposed on the side of the fixed portion 32 close to the front shell 2, that is, the extension surface of the first connecting portion 51 facing away from the front shell 2 can be connected to the extension surface of the fixed portion 32 close to the front shell 2, thereby wrapping the fixed portion 32 within the telescopic member 5, thereby further improving the sealing between the connecting portion and the fixed portion 32. When the telescopic member 5 is disposed inside the sewage suction bucket 1, the first connecting portion 51 can be disposed on the side of the fixed portion 32 away from the front shell 2, that is, the extension surface of the first connecting portion 51 close to the front shell 2 can be connected to the extension surface of the fixed portion 32 facing away from the front shell 2, thereby wrapping the fixed portion 32 within the telescopic member 5, thereby further improving the sealing between the connecting portion and the fixed portion 32.

[0090] As shown in Figures 1 to 4, 6, and 10, the dirt suction assembly provided herein may further include a first pressing member 6. The first pressing member 6 may be located on a side of the first connecting portion 51 facing away from the fixing portion 32, and may be connected to both the first connecting portion 51 and the fixing portion 32. This arrangement allows the first pressing member 6 to compress the first connecting portion 51 and the fixing portion 32, further enhancing the connection stability between the first connecting portion 51 and the fixing portion 32.

[0091] In this embodiment, the fixing portion 32, the first connecting portion 51, and the first pressing member 6 can all be annular structures disposed around the outer circumference of the main body portion 31. This configuration can increase the pressing area of ​​the first pressing member 6, thereby further improving the connection stability and sealing performance between the first connecting portion 51 and the fixing portion 32.

[0092] In one embodiment, the first connecting portion 51, the fixing portion 32 and the first pressing member 6 can be connected by connecting members 10 such as screws and bolts, so as to ensure a stable connection while facilitating the disassembly of each component for easy repair and replacement of damaged components.

[0093] In this embodiment, through holes 9 may be provided on the first connecting part 51, the fixing part 32 and the first clamping part 6, and the connecting part 10 may pass through the through holes 9 on the first connecting part 51, the fixing part 32 and the first clamping part 6 to connect the first connecting part 51, the fixing part 32 and the first clamping part 6.

[0094] There can be multiple through holes 9 on the first connecting part 51, the fixing part 32 and the first clamping part 6, and there can also be multiple connecting parts 10. The multiple connecting parts 10 can pass through the multiple through holes 9 respectively, thereby improving the stability of the connection between the first connecting part 51, the fixing part 32 and the first clamping part 6.

[0095] However, it is not limited thereto, the first connecting portion 51, the fixing portion 32 and the first pressing member 6 may also be connected by other connection methods, such as bonding, riveting, etc., which may be selected and set according to actual needs, which are all within the scope of protection of the present disclosure.

[0096] In one embodiment of the present disclosure, as shown in Figures 1 to 5 and 10, the second connecting portion 53 can extend in a direction away from the outer circumferential surface of the main body 31, and one extended surface of the second connecting portion 53 can be connected to the wall of the sewage suction bucket 1. It should be noted that the extended surface of the second connecting portion 53 can be two surfaces of the second connecting portion 53 in the first direction X.

[0097] Since the area of ​​the extension surface of the second connection part 53 is large, when one extension surface of the second connection part 53 is connected to the barrel wall of the sewage suction barrel 1, the connection area between the second connection part 53 and the sewage suction barrel 1 can be increased, thereby improving the connection stability between the second connection part 53 and the sewage suction barrel 1.

[0098] In one embodiment, the second connection portion 53 can be connected to the wall of the sewage suction bucket 1 where the sewage suction pipe opening 12 is provided, so as to facilitate the connection of the second connection portion 53 .

[0099] The second connecting portion 53 can be an annular structure disposed around the outer circumference of the main body 31. This arrangement further increases the connection area between the second connecting portion 53 and the sewage suction bucket 1, further improving the stability of the connection between the second connecting portion 53 and the sewage suction bucket 1. Furthermore, when an extended surface of the second connecting portion 53 is connected to the wall of the sewage suction bucket 1, a good seal is achieved between the second connecting portion 53 and the sewage suction bucket 1, preventing pressure loss or water leakage at the connection point between the second connecting portion 53 and the sewage suction bucket 1.

[0100] As shown in Figures 1 to 4, 7, and 10, the sewage suction assembly provided herein may further include a second pressing member 7. This second pressing member 7 may be located on the side of the second connecting portion 53 facing away from the wall of the sewage suction bucket 1 and may be connected to both the second connecting portion 53 and the wall of the sewage suction bucket 1. This arrangement allows the second pressing member 7 to press the second connecting portion 53 against the wall of the sewage suction bucket 1, further enhancing the stability of the connection between the second connecting portion 53 and the sewage suction bucket 1.

[0101] In this embodiment, the second connecting portion 53 and the second pressing member 7 can both be annular structures disposed around the outer circumference of the main body 31. This configuration can increase the pressing area of ​​the second pressing member 7, thereby further improving the connection stability and sealing performance between the second connecting portion 53 and the sewage suction bucket 1.

[0102] In one embodiment, the second connecting part 53, the barrel wall of the sewage suction barrel 1 and the second clamping member 7 can be connected by connecting parts 10 such as screws and bolts, so as to ensure a stable connection while facilitating the disassembly of the second connecting part 53 and the second clamping member 7 to facilitate the repair and replacement of damaged parts.

[0103] In this embodiment, the second connecting part 53, the barrel wall of the sewage suction barrel 1 and the second pressing member 7 can be provided with a through hole 9, and the connecting part 10 can pass through the through hole 9 on the second connecting part 53, the barrel wall of the sewage suction barrel 1 and the second pressing member 7 to connect the second connecting part 53, the barrel wall of the sewage suction barrel 1 and the second pressing member 7.

[0104] There can be multiple through holes 9 on the second connecting part 53, the barrel wall of the sewage suction barrel 1 and the second pressing member 7, and there can also be multiple connecting members 10. The multiple connecting members 10 can pass through the multiple through holes 9 respectively, thereby improving the stability of the connection between the second connecting part 53, the barrel wall of the sewage suction barrel 1 and the second pressing member 7.

[0105] However, the present invention is not limited thereto, and the second connecting portion 53, the barrel wall of the sewage suction barrel 1 and the second pressing member 7 may also be connected by other connection methods, such as bonding, riveting, etc., which may be selected and set according to actual needs, all within the scope of protection of the present disclosure.

[0106] In one embodiment, the telescopic member 5 can be located outside the sewage suction bucket 1. Such a configuration can facilitate the arrangement of the telescopic member 5 and can prevent the sewage or solid waste in the sewage suction bucket 1 from corroding the telescopic member 5 and causing damage to the telescopic member 5, thereby increasing the service life of the sewage suction assembly.

[0107] In one embodiment of the present disclosure, the telescopic member 5 may be made of a flexible rubber material, which has a high sealing performance and good elasticity. This improves the sealing performance of the connection between the telescopic member 5, the sewage suction pipe 3, and the sewage suction bucket 1, and ensures that the sewage suction pipe 3 can be smoothly retracted to the first position after the sewage is sucked. However, the telescopic member 5 is not limited to this and may be made of other materials, which can be selected and configured according to actual needs.

[0108] In another embodiment of the present disclosure, the suction pipe 3 can be elastic, for example, it can be a hose. Furthermore, the suction pipe 3 can be fixedly connected to the suction bucket 1. When the end of the suction pipe 3, away from the suction bucket 1, is in the second position, the suction pipe 3 is stretched due to its fixed connection to the suction bucket 1, resulting in a restoring force within the suction pipe 3. When suction is complete and the suction pipe 3 is separated from the cleaning unit, the suction pipe 3 can retract due to its internal restoring force, returning the end away from the suction bucket 1 to the second position.

[0109] As shown in Figures 1 to 4 and 10, in one embodiment of the present disclosure, the sewage suction pipe 3 can be provided with a second mounting portion 33. The second mounting portion 33 can be disposed on the outer circumference of the sewage suction pipe 3, and the first mounting portion 41 can be connected to the second mounting portion 33. This arrangement provides a more stable mounting position for the first mounting portion 41. Furthermore, this arrangement avoids the problem of a loose seal at the connection caused by directly connecting the first mounting portion 41 to the main body 31, thereby preventing pressure relief and water leakage at the connection.

[0110] In one embodiment, the sewage suction pipe 3 can be an integrated structure, that is, the main body 31, the fixing portion 32, and the second mounting portion 33 can be manufactured through an integrated molding process, without the need to use bonding, welding, or other connection methods to connect the main body 31 and the fixing portion 32, or the main body 31 and the second mounting portion 33. This configuration can improve the production efficiency of the sewage suction pipe 3, facilitate the mass production of the sewage suction pipe 3, and also reduce the number of connection points within the sewage suction pipe 3, thereby increasing the service life of the sewage suction pipe 3.

[0111] However, the present invention is not limited thereto, and the sewage suction pipe 3 may also be a split structure, that is, the main body 31 , the fixing portion 32 and the second mounting portion 33 may be manufactured separately, and the components may be connected by bonding, welding or other connection methods to form the sewage suction pipe 3 .

[0112] In one embodiment, the first mounting portion 41 may be recessed, and the second mounting portion 33 may be protruding. The second mounting portion 33 may be located within the first mounting portion 41, allowing the first mounting portion 41 to be connected to the second mounting plate. For example, the second mounting portion 33 may be inserted into the first mounting portion 41, and the first mounting portion 41 and the second mounting portion 33 may be connected via the connector 10. However, the present invention is not limited thereto. The first mounting portion 41 and the second mounting portion 33 may also be connected by snapping, riveting, bonding, or other connection methods.

[0113] In one embodiment, the first mounting portion 41 is a protruding structure, and the second mounting portion 33 is a recessed structure. The first mounting portion 41 can be located within the second mounting portion 33, so that the first mounting portion 41 can be connected to the second mounting portion 33. For example, the first mounting portion 41 can be extended into the second mounting portion 33 and connected to the second mounting portion 33 via the connector 10; however, the present invention is not limited to this. The first mounting portion 41 and the second mounting portion 33 can also be connected by snapping, riveting, bonding, or other connection methods.

[0114] In one embodiment, the first mounting portion 41 may be a protruding structure, and the second mounting portion 33 may be a protruding structure. For example, the two protruding structures may be directly connected via the connector 10 to achieve the connection between the first mounting portion 41 and the second mounting portion 33; however, the present invention is not limited thereto, and the two protruding structures may be connected by bonding, welding, or other connection methods.

[0115] In one embodiment of the present disclosure, the linkage mechanism 4 can be disposed in the second accommodating cavity 21 and rotatably connected to the front housing 2. This arrangement facilitates the installation of the linkage mechanism 4 and allows the front housing 2 to protect the linkage mechanism 4. Furthermore, it prevents the sewage or solid waste in the suction bucket 1 from damaging the linkage mechanism 4, thereby increasing the service life of the suction assembly.

[0116] In this embodiment, when the linkage mechanism 4 is located in the second accommodating cavity 21 , the second mounting portion 33 may also be located in the second accommodating cavity 21 , thereby facilitating the connection between the first mounting portion 41 and the second mounting portion 33 .

[0117] In this embodiment, the front shell 2 may further include a second opening 23. The second opening 23 may be provided on a surface of the front shell 2 opposite the dirt suction bucket 1 and communicate with the second accommodating chamber 21. The second opening 23 may expose the trigger portion 42. With this arrangement, when the cleaning host needs to suction dirt, the cleaning host may trigger the trigger portion 42 through the second opening 23, causing the trigger portion 42 to switch to the second state. This allows the linkage mechanism 4 to move the end of the dirt suction pipe 3 away from the dirt suction bucket 1 from the first position to the second position, facilitating docking of the dirt suction pipe 3 with the cleaning host.

[0118] In one embodiment of the present disclosure, the linkage structure may include a linkage member 43, which may include a first sub-linkage member 431 and a second sub-linkage member 432. The first sub-linkage member 431 may be closer to the front housing 2 than the second sub-linkage member 432, and the trigger portion 42 may be disposed on the first sub-linkage member 431 so that the cleaning host can contact the trigger portion 42.

[0119] In one embodiment, when the second mounting portion 33 is a protruding structure, there may be a gap between one end of the first sub-linking member 431 close to the second mounting portion 33 and one end of the second sub-linking member 432 close to the second mounting portion 33, and the gap may be the above-mentioned recessed structure, that is, the gap is the first mounting portion 41.

[0120] In one embodiment, when the second mounting portion 33 is a protruding structure, the first mounting portion 41 may be a recessed structure, and the recessed structure may be located at an end of the second sub-linking member 432 close to the second mounting portion 33 .

[0121] In one embodiment, when the second mounting portion 33 is a protruding structure, the first mounting portion 41 may also be a protruding structure, and the protruding structure may be located at an end of the second sub-linking member 432 close to the second mounting portion 33 .

[0122] In one embodiment, when the second mounting portion 33 is a protruding structure, the first mounting portion 41 may be a recessed structure, and the recessed structure may be located at an end of the first sub-linking member 431 close to the second mounting portion 33 .

[0123] In one embodiment, when the second mounting portion 33 is a protruding structure, the first mounting portion 41 may also be a protruding structure, and the protruding structure may be located at an end of the first sub-linking member 431 close to the second mounting portion 33 .

[0124] In one embodiment of the present disclosure, as shown in FIG10 , the linkage mechanism 4 may further include an elastic element 44. The elastic element 44 may be disposed between the linkage member 43 and a surface of the front shell 2 that is opposite to the dirt suction bucket 1, and / or the elastic element 44 may be disposed at an end of the dirt suction pipe 3 away from the dirt suction bucket 1, and when the trigger portion 42 is in the second state, the elastic element 44 is in a compressed state. It is understood that when the elastic element 44 is disposed between the linkage member 43 and a surface of the front shell 2 that is opposite to the dirt suction bucket 1, and when the trigger portion 42 is in the second state, the linkage member 43 and the front shell 2 may compress the elastic element 44, thereby imparting a restoring force to the elastic element 44; when the elastic element 44 is disposed at an end of the dirt suction pipe 3 away from the dirt suction bucket 1, and when the trigger portion 42 is in the second state, the cleaning host and the dirt suction pipe 3 may compress the elastic element 44, thereby imparting a restoring force to the elastic element 44.

[0125] For example, the elastic element 44 may be a spring, but is not limited thereto. The elastic element 44 may also be other elastic structural members and may be configured according to actual needs.

[0126] Therefore, when the trigger part 42 is in the second state, the elastic element 44 has a restoring force inside. When the sewage suction work is completed and the sewage suction pipe 3 is separated from the cleaning host, the restoring force of the elastic element 44 can be used to further drive the sewage suction pipe 3 to retract, so as to ensure that the end of the sewage suction pipe 3 away from the sewage suction bucket 1 retracts from the second position to the first position.

[0127] In one embodiment, when the linkage 43 includes a first sub-linkage 431 and a second sub-linkage 432 , the elastic element 44 may be disposed between the second sub-linkage 432 and a surface of the front shell 2 opposite to the sewage suction bucket 1 .

[0128] In one embodiment of the present disclosure, as shown in Figures 1 to 4 and 8 to 10, the sewage suction assembly may further include a docking member 8. The docking member 8 may be installed at the end of the sewage suction pipe 3 away from the sewage suction bucket 1 to facilitate docking of the sewage suction pipe 3 with the cleaning host.

[0129] In one embodiment, a fixing platform 34 may be provided at the end of the sewage suction pipe 3 away from the sewage suction bucket 1. The fixing platform 34 may protrude from the outer circumference of the sewage suction pipe 3. The docking member 8 may be provided with a fixing groove 81. The fixing groove 81 on the docking member 8 is fixed to the fixing platform 34 on the sewage suction pipe 3, so that the docking member 8 is installed at the end of the sewage suction pipe 3 away from the sewage suction bucket 1.

[0130] In one embodiment, the fixing groove 81 can be fixed to the fixing platform 34 using a snap-fit ​​connection. That is, the fixing platform 34 can be snapped into the fixing groove 81 to achieve a snap-fit ​​connection. However, the fixing groove 81 can also be connected to the sewage suction pipe 3 using a connector 10 or bonding, and the fixing groove 81 can also be fixed to the fixing platform 34 on the sewage suction pipe 3. This is also within the scope of protection of the present disclosure.

[0131] In one embodiment, the docking member 8 can be made of soft rubber. Because the soft rubber has cushioning properties, this arrangement can act as a buffer when the suction pipe 3 is docked with the cleaning main unit, protecting the suction pipe 3 and the cleaning main unit from damage during the docking process. It can also maintain airtightness with the cleaning main unit to improve the suction effect. However, this is not limiting. The docking member 8 can also be other structural components, and can be selected and configured according to actual needs.

[0132] In one embodiment of the present disclosure, as shown in FIG9 , the sewage suction assembly may further include: an air-blocking structure 20. The air-blocking structure 20 may be disposed within the sewage suction pipe 3, and / or may be disposed at at least one end of the sewage suction pipe 3. When the sewage suction assembly is performing sewage suction, the air-blocking structure 20 may be opened to facilitate the normal operation of the sewage suction operation; when the sewage suction assembly completes sewage suction, the air-blocking structure 20 may be closed to prevent the odorous gas within the sewage suction barrel 1 from being released into the external environment through the sewage suction pipe 3, thereby avoiding secondary pollution to the external environment.

[0133] In one embodiment, the gas blocking structure 20 can be provided at the end of the sewage suction pipe 3 away from the sewage suction bucket 1. Compared with the embodiment in which the gas blocking structure 20 is provided at the other end of the sewage suction pipe 3, this embodiment can not only use the gas blocking structure 20 to block the odorous gas in the sewage suction bucket 1, but also block the odorous gas in the entire sewage suction pipe 3, thereby achieving a better gas blocking effect.

[0134] At the same time, compared with the embodiment in which the gas-blocking structure 20 is arranged in the sewage suction pipe 3, this embodiment can more conveniently install and disassemble the gas-blocking structure 20, reducing the difficulty and workload of installing and disassembling the gas-blocking structure 20; and, it can also block the odorous gas in the entire sewage suction pipe 3, thereby improving the gas-blocking effect.

[0135] In addition, compared with the embodiment in which the air-blocking structures 20 are provided at both ends of the sewage suction pipe 3, this embodiment can reduce the number of air-blocking structures 20 while ensuring a good air-blocking effect, thereby reducing the manufacturing cost of the sewage suction component.

[0136] In one embodiment, the air blocking structure 20 may be a air blocking valve, but is not limited thereto. The present disclosure does not limit the specific type of the air blocking structure 20 and may be selected and configured according to actual needs, all within the scope of protection of the present disclosure.

[0137] Another aspect of the present disclosure provides a cleaning device. As shown in Figures 1 to 10, the cleaning device may include a cleaning main unit and a sewage suction assembly. The cleaning main unit may be a floor scrubber, robot vacuum cleaner, or other cleaning device that needs to clean sewage and / or solid waste. The sewage suction assembly may be the sewage suction assembly described above. Furthermore, the end of the sewage suction pipe 3, distal to the sewage suction barrel 1, can be docked with the cleaning main unit through a first opening 22.

[0138] It should be noted that the present disclosure has already described in detail the specific structure and beneficial effects of the sewage suction component in the previous embodiment, so in this embodiment, the specific structure and beneficial effects of the sewage suction component will not be repeated. You can refer to the specific description in the previous embodiment, which is all within the scope of protection of the present disclosure.

[0139] 1 to 10 , the cleaning device provided by the present disclosure includes the aforementioned suction assembly, which includes: a suction bucket 1, a front shell 2, a suction pipe 3, and a linkage mechanism 4. The suction pipe 3 is connected to the first accommodating chamber 11, and at least a portion of the suction pipe 3 is disposed within the second accommodating chamber 21 of the front shell 2. Furthermore, the first opening 22 of the front shell 2 can expose at least a portion of the end of the suction pipe 3 away from the suction bucket 1. Furthermore, when the trigger portion 42 is in the first state, the end of the suction pipe 3 away from the suction bucket 1 can be in a first position; when the trigger portion 42 is in the second state, the end of the suction pipe 3 away from the suction bucket 1 is in a second position. Furthermore, in the extension direction of the suction pipe 3, the second position is further away from the suction bucket 1 than the first position.

[0140] Thus, when it is necessary to divert the sewage and solid waste in the cleaning main unit into the sewage bucket, the trigger device can be placed in the second state, so that the end of the sewage suction pipe 3 away from the sewage suction bucket 1 is closer to the cleaning main unit, making it convenient to connect the end of the sewage suction pipe 3 away from the sewage suction bucket 1 with the cleaning main unit through the first opening 22; when the sewage suction is completed, the sewage suction pipe 3 can be separated from the cleaning main unit, and the end of the sewage suction pipe 3 away from the sewage suction bucket 1 can be restored to the first position to be retracted into the second accommodating chamber 21, so as to reduce the probability of damage to the sewage suction pipe 3, thereby effectively improving the service life of the sewage suction component, and thus improving the service life of the cleaning equipment.

[0141] Furthermore, as can be seen from the above, the pipeline in the sewage suction assembly provided by the present disclosure has only one sewage suction pipe 3, so the pipeline in the sewage suction assembly provided by the present disclosure is not spliced ​​together by multiple sections of pipelines, which can avoid the appearance of interfaces in the pipeline, and can also prevent sewage and solid waste from remaining at the interfaces, effectively avoiding the problem of odor or clogging the pipeline, thereby improving the sewage suction effect of the sewage suction assembly. At the same time, such a setting also improves the sealing of the sewage suction pipe 3, avoiding the problem of interfaces in the pipeline and water leakage at the interfaces, thereby further improving the sewage suction effect of the sewage suction assembly, and further improving the sewage suction effect of the cleaning equipment.

[0142] Other embodiments of the present disclosure will readily occur to those skilled in the art after considering the specification and practicing the invention disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art not disclosed herein. The description and examples are to be considered as exemplary only, with the true scope and spirit of the present disclosure being indicated by the appended claims.
