Therefore, cleaning agencies are gradually replacing manual cleaning and are widely used in life and work. During the use of cleaning equipment, it is necessary to open the cover to maintain and inspect the internal parts of the equipment.

[0003] Currently, the method of removing the cover is complicated, and liquid backflow is likely to occur after the cover is removed, resulting in a poor user experience.

[0004] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is that existing cleaning equipment has problems such as inconvenient removal of the cover plate and backflow.

When the cover plate is detached from the base, the inlet pipe separates from the flow channel, and the elastic component blocks the opening of the flow channel. When the cover plate is mounted on the base, at least a portion of the inlet pipe compresses the elastic component to open the opening, allowing the inlet pipe to communicate with the water distributor through the flow channel. The elastic component also provides a repulsive force during the disassembly of the cover plate from the base.

[0008] Optionally, the elastic component includes an elastic element, one end of which is connected to the flow channel; a piston, which is movably disposed inside the flow channel, and the other end of the elastic element is connected to the piston. The elastic element provides elastic force for the piston to block the opening of the flow channel away from the distributor.

[0009] Optionally, the base is provided with a receiving groove for installing cleaning parts, and at least one locking structure is provided between the cover and the base along the extending direction of the receiving groove, the locking structure locking or unlocking the base and the cover.

[0014] Optionally, the inlet pipe includes a squeeze protrusion with an inlet. The squeeze protrusion extends into or out of the flow channel.

[0035] This invention solves the problems of inconvenient disassembly of the cover plate and backflow in existing cleaning equipment.

[0036] Example 1

[0037] This embodiment provides a cleaning mechanism, such as Figures 1 to 9 As shown, the cleaning mechanism includes a base 10, a water distributor 30, a cover plate 20, and an elastic component. The base 10 is provided with an inlet pipe 80. The water distributor 30 is installed on the cover plate 20. The cover plate 20 has a flow channel 40 that communicates with the water distributor 30. The base 10 and the cover plate 20 are detachably connected. The elastic component is compressed and located inside the end of the flow channel 40 away from the water distributor 30.

[0038] When the cover plate 20 is disassembled from the base 10, the inlet pipe 80 separates from the flow channel 40, and the elastic component blocks the opening of the flow channel 40; when the cover plate 20 is installed on the base 10, at least a portion of the inlet pipe 80 squeezes the elastic component to open the opening, so that the inlet pipe 80 is connected to the water distributor 30 through the flow channel 40; wherein, the elastic component is also used to provide repulsive force during the disassembly of the cover plate 20 from the base 10.

[0039] Specifically, the elastic component in this application has the technical effect of sealing the flow channel 40 after the cover plate 20 and the base 10 are disassembled. By sealing the opening of the flow channel 40, the elastic component prevents the backflow of liquid inside the distributor 30, thus avoiding leakage and improving cleanliness, which is beneficial to improving the user experience. At the same time, the elastic component has a repulsive force that drives the cover plate 20 and the base 10 to separate, thereby assisting in the opening operation and improving the convenience of opening the cover plate 20. The elastic component has the technical effects of sealing the flow channel 40 and providing a repulsive force, effectively solving the problems of inconvenient disassembly of the cover plate 20 and backflow in existing cleaning equipment.

[0040] Furthermore, the base 10 has a receiving groove, and the cleaning mechanism also includes a cleaning component movably installed inside the receiving groove. The water distributor 30 is used to spray water onto the cleaning component. The cleaning component may be a roller brush.

[0041] In this embodiment, the flow channel 40 has a through hole that communicates with the inlet end of the distributor 30. After the liquid inside the inlet pipe 80 enters the flow channel 40, it passes through the through hole into the distributor 30. The through hole is located at the end away from the opening of the flow channel 40, that is, close to the distributor 30, so as to facilitate the liquid inside the inlet pipe 80 to enter the distributor 30 after flowing through the through hole.

[0042] like Figures 3 to 5 As shown, the end of the flow channel 40 away from the water distributor 30 has a circumferential flange extending toward the interior of the flow channel 40. The circumferential flange forms an opening, and the end face of the circumferential flange toward the water distributor 30 forms a support surface 410, which is used to support the elastic component.

[0043] Specifically, the open end of the flow channel 40 is provided with a support surface 410, which supports an elastic component. When the cover plate 20 and the base 10 are separated, the elastic component can abut against the support surface 410 and seal the opening. At this time, the opening of the flow channel 40 is blocked. Therefore, even if the liquid inside the distributor 30 flows back into the interior of the flow channel 40, it will not flow to the outer area of ​​the flow channel 40, thus achieving the technical effect of preventing backflow when the cover plate 20 is removed.

[0044] Furthermore, the elastic component is disposed inside the flow channel 40 in a compressed state to block the opening of the flow channel 40.

[0045] It should be noted that, not limited to the end of the flow channel 40 away from the distributor 30 having a circumferential flange structure to form an opening, the diameter of the flow channel 40 away from the distributor 30 can also gradually decrease to form a narrow channel, so that the elastic component in a compressed state can block the opening. Of course, other similar structures are also possible.

[0046] like Figures 3 to 5 As shown, the elastic component includes an elastic element 60 and a piston 50. One end of the elastic element 60 is connected to the flow channel 40, and the piston 50 is movably disposed inside the flow channel 40. The other end of the elastic element 60 is connected to the piston 50. The elastic element 60 provides elastic force for the piston 50 to block the opening of the flow channel 40 away from the water distributor 30.

[0047] Specifically, the elastic element 60 of the compressed elastic component is in a compressed state. The elastic element 60 provides elastic force to the piston 50 to abut against the support surface 410, so as to block the opening of the flow channel 40. Since the elastic element 60 can expand and contract under external force, after the cover plate 20 is installed on the base 10, the liquid inlet pipe 80 on the base 10 moves from the opening to the inside of the flow channel 40. The liquid inlet pipe 80 squeezes the piston 50 to move toward the end of the flow channel 40 away from the opening. The liquid inlet pipe 80 squeezes the piston 50 to move so as to drive the elastic element 60 to be compressed.

[0048] As the piston 50 moves away from the support surface 410, when the piston 50 disengages from the support surface 410, the liquid inside the inlet pipe 80 can flow into the flow channel 40 and then through the through hole into the distributor 30 to supply water. This ensures that when the cover plate 20 is separated from the base 10, the elastic component seals the opening of the flow channel 40, and when the cover plate 20 is installed on the base 10, the inlet pipe 80 can supply liquid to the distributor 30.

[0049] Furthermore, the elastic element 60 is housed inside the flow channel 40, and the elastic element 60 is connected to the inner wall or bottom of the flow channel 40, so as to provide driving force to the piston 50 under compression.

[0050] It should be noted that the area of ​​the surface of the piston 50 that abuts against the support surface 410 is larger than the area of ​​the opening, so that the piston 50 can block the support surface 410 and thus block the opening of the flow channel 40.

[0051] In this embodiment, the elastic element 60 is a spring.

[0052] like Figure 3 and Figure 4As shown, the inlet pipe 80 includes a squeeze protrusion with an inlet. The squeeze protrusion extends into or out of the flow channel 40. The cleaning mechanism also includes a seal, which is fitted onto the squeeze protrusion. When the squeeze protrusion extends into the flow channel 40, the inlet communicates with the flow channel 40. The squeeze protrusion abuts against the inner wall of the flow channel 40 through the seal to form a sealed cavity inside the flow channel 40. The inlet is located inside the sealed cavity.

[0053] Specifically, the extrusion protrusion is used to expel the piston 50 away from the opening when the cover plate 20 and the base 10 are installed, so as to realize the connection between the flow channel 40 and the liquid inlet pipe 80.

[0054] Furthermore, the sealing element can be a sealing sleeve, which is fitted onto the extrusion protrusion so that after the extrusion protrusion enters the interior of the flow channel 40, the sealing sleeve abuts against the interior of the flow channel 40; the sealing element can also be multiple sealing rings spaced apart on the extrusion protrusion, with the multiple sealing rings positioned between the inner wall surface of the flow channel 40 and the outer wall surface of the extrusion protrusion to achieve a seal.

[0055] Furthermore, a liquid inlet is provided on the top of the extrusion protrusion, with the liquid inlet located in the top area of ​​the extrusion protrusion, so as to allow liquid to flow into the interior of the flow channel 40. After the extrusion protrusion extends into the interior of the flow channel 40, a sealing cavity is formed in the interior area of ​​the flow channel 40 away from the base 10 by a sealing member, so that the liquid flowing out of the liquid inlet first enters the interior of the sealing cavity and then enters the interior of the distributor.

[0056] like Figures 1 to 9 As shown, along the extension direction of the receiving groove, at least one set of locking structures is provided between the cover plate 20 and the base 10, the locking structures locking or unlocking the base 10 and the cover plate 20.

[0057] Specifically, in order to achieve a detachable connection between the base 10 and the cover plate 20, and to provide a driving force for the cover plate 20 to move away from the base 10 by the elastic member 60 in a compressed state, a locking structure is provided between the base 10 and the cover plate 20, so as to lock or unlock the cover plate 20 and the base 10 by controlling the locking structure.

[0058] Furthermore, when multiple sets of locking structures are provided, the multiple sets of locking structures are spaced apart along the extension direction of the receiving groove, and at least one set of locking structures is an active locking structure, and at least another set of locking structures is a passive locking structure.

[0059] The active locking structure is a locking structure that requires manual control to unlock, while the passive locking structure does not require manual intervention and unlocks automatically following the active locking structure. In this application, by incorporating both active and passive locking structures, the cover plate 20 and the base 10 are locked together.

[0060] It should be noted that one or more active locking structures and passive locking structures can be provided. When multiple structures are provided, the active locking structures are spaced apart along the extension direction of the receiving groove, and the passive locking structures are spaced apart along the extension direction of the receiving groove.

[0061] In this embodiment, one active locking structure and one passive locking structure are provided, and the active locking structure and the passive locking structure are provided at both ends of the base 10.

[0062] like Figures 1 to 9 As shown, the active locking structure includes a release button 70, a first locking member 220, and a first mating member 110. The release button 70 is mounted on the cover plate 20 or the base 10. The first locking member 220 is movably disposed on the cover plate 20 and moves along the extension direction of the receiving groove. The release button 70 is drivenly connected to the first locking member 220. The base 10 is provided with the first mating member 110, which has a locking space with an opening along the extension direction of the receiving groove. At least a portion of the first locking member 220 extends into or retracts from the locking space.

[0063] Specifically, when it is necessary to separate the cover plate 20 from the base 10, since the release button 70 is driven to connect with the first locking member 220, the release button 70 can be pressed to drive the first locking member 220 to disengage from the first mating member 110. At the same time, under the repulsive force of the elastic component, the cover plate 20 moves away from the base 10 to achieve the separation of the cover plate 20 from the base 10.

[0064] Furthermore, the release button 70 can drive the first locking member 220 to move along the extension direction of the receiving groove to disengage from the first mating member 110.

[0065] Furthermore, the first locking member 220 is a locking slider, and the first mating member 110 is a locking groove, so that the first locking member 220 can extend into or exit the locking groove to realize the locking and unlocking of the active locking structure.

[0066] In this embodiment, the passive locking structure includes a second locking member 120 and a second mating member 210. The second locking member 120 is disposed on the base 10 and extends along the extension direction of the receiving groove. The second locking member 120 is made of an elastic deformable material. The cover plate 20 is provided with the second mating member 210, and the second mating member 210 is provided with a locking groove that opens along the extension direction of the receiving groove. The second locking member 120 is disengaged from the second mating member 210, or at least a portion of the second locking member 120 and the second mating member 210 extends into the locking groove.

[0067] Specifically, when the cover plate 20 is placed on the base 10, at least a portion of the second locking member 120 extends into the interior of the locking groove to lock the base 10 and the cover plate 20. When it is necessary to separate the cover plate 20 from the base 10, the release button 70 is activated to disengage the first locking member 220 from the first mating member 110. At this time, the cover plate 20 in the area of ​​the active locking structure is disengaged from the base 10. Then, the cover plate 20 is directly moved laterally to disengage the second locking member 120 from the second mating member 210, and the cover plate 20 can be removed.

[0068] When it is necessary to lock the cover plate 20 onto the base 10, the cover plate 20 of this application can be moved directly toward the base 10 during installation, thereby achieving vertical movement to the base 10 for installation, which has the technical effect of facilitating installation.

[0069] Further, the cover plate 20 is moved toward the base 10, and the release button 70 is pressed to make the first locking member 220 disengage from the first mating member 110. At this time, the cover plate 20 in the active locking structure area can directly abut against the base 10. Then, the release button 70 is released so that at least a part of the first locking member 220 extends into the interior of the first mating member 110. At the same time, since the second locking member 120 is made of elastic material, the second locking structure in the passive locking structure area of ​​the cover plate 20 deforms during installation so that after the cover plate 20 abuts against the base 10, the second locking member 120 enters into the interior of the second mating member 210, thereby locking the cover plate 20.

[0070] Example 2

[0071] This embodiment provides a cleaning device, which includes a cleaning component and the cleaning mechanism in Embodiment 1. The cleaning component is movably mounted on the cleaning mechanism.

[0072] Specifically, the cleaning equipment can be a floor scrubber or other similar structural components.

[0073] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0074] 1. The elastic component in this application has the technical effect of sealing the flow channel 40 after the cover plate 20 and the base 10 are removed. By sealing the opening of the flow channel 40, the elastic component prevents the liquid inside the distributor 30 from flowing back and causing leakage, thereby improving cleanliness and enhancing the user experience.

[0075] 2. The elastic component has a repulsive force that drives the cover plate 20 and the base 10 to separate, so as to assist the opening operation and improve the convenience of opening the cover plate 20.

[0076] 3. The elastic component has the technical effect of both sealing the flow channel 40 and providing repulsive force, which effectively solves the problems of inconvenient disassembly of the cover plate 20 and backflow in existing cleaning equipment.

[0077] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. Based on the embodiments of the present invention, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the scope of protection of the present invention.
