Abstract

The application is suitable for the technical field of cleaning equipment, and discloses a water-leakage-proof cleaning roller and a cleaning tool, wherein the water-leakage-proof cleaning roller comprises a roller support and a roller sponge wrapped outside the roller support; one end of the roller support is provided with a cavity, and the other end is provided with an extension hinge mechanism; and water-locking mechanisms are arranged at both ends of the roller sponge respectively to prevent liquid from flowing out during roller cleaning. Since the water-locking mechanisms are arranged at both ends of the roller sponge respectively to avoid water leakage on the side surface of the roller, the water-locking mechanisms can reduce the friction between the roller sponge and the cleaning head shell, improve the water tightness between the roller sponge and the cleaning head shell, avoid large friction force from reducing the service life of the cleaning roller, improve the effective energy of the battery, and avoid the water absorption and moisture retention performance of the roller sponge from being reduced. In addition, the water-locking mechanisms reduce the elastic deformation amount between the end of the sponge layer and the side wall of the cleaning head shell, naturally reduce the expansion force of the sponge layer against the side wall of the cleaning head shell during the process of the sponge layer becoming dry and hard, and improve the service life of the cleaning head shell.

Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and more particularly to a leak-proof cleaning roller and cleaning tool. Background Technology

[0002] To clean the cleaning drum, a closed cleaning space connected to the water supply system is usually set up to clean specific sections of the drum. Clean water is provided to clean the drum, and then the wastewater is pumped away. The cleaning drum should cover as much of the area to be cleaned as possible. The sponge layer of the cleaning drum has an elastic interference fit at both ends against the side walls of the cleaning head housing in the width direction. This ensures that the portion of the cleaning drum enclosed in the cleaning space will not leak when subjected to high-speed water flow.

[0003] In existing technologies, cleaning rollers are typically fitted with a motor at one end, which is fixed to the side wall of the cleaning head. The other end is secured to the other side wall of the cleaning head via a spring-loaded button. To prevent water from failing to be ejected during high-speed rotation, the sponge layer and the side walls experience significant compression. This generates considerable resistance during high-speed operation, reducing motor efficiency and potentially decreasing the overall battery life of the floor cleaner, resulting in a poor user experience. Conversely, insufficient compression between the sponge layer and the side walls can lead to water leakage. Therefore, it is necessary to find a solution that both retains moisture in the sponge layer and reduces friction between the sponge layer and the side walls of the cleaning head. Summary of the Invention

[0004] The main technical problem solved by the present invention is to provide a water-proof cleaning roller and cleaning tool, wherein the water-proof cleaning roller can prevent water leakage from the side of the roller and reduce the friction of the roller.

[0005] To solve the above problems, the present invention provides a water-proof cleaning roller, which includes a roller support and a roller sponge covering the outside of the roller support. One end of the roller support is provided with a cavity and the other end is provided with a telescopic rotating shaft mechanism. Water-locking mechanisms are provided at both ends of the roller sponge to prevent liquid from flowing out during roller cleaning.

[0006] Preferably, the water-locking mechanism includes an inwardly inclined surface at any position between the outer diameter and the inner diameter in the thickness direction of the roller sponge, and forms an annular arc surface in the thickness of the roller sponge.

[0009] Preferably, the telescopic pivot mechanism includes a pivot fixed at one end to a fixed base that moves only linearly, an elastic component sleeved on the pivot to keep the pivot in an extended state, and a pivot cover covering the end of the pivot. A bearing is provided between the pivot cover and the pivot. When force is applied to the pivot cover, the pivot moves linearly inward. When released, the elastic component causes the pivot and the pivot cover to extend outward.

[0010] Preferably, the water-locking mechanism includes water-blocking rings that protrude from the main body of the roller sponge at both ends of the roller sponge.

[0011] Preferably, the outer side of the water-retaining ring is flush with the outer diameter of the roller sponge.

[0013] Preferably, the outer side of the water-blocking ring is provided with directional deformation grooves, which are distributed in the circumferential direction of the water-blocking ring.

[0014] Preferably, the cross-section of the directional deformation groove is trapezoidal.

[0015] Preferably, both the inner and outer sides of the water-blocking ring are outwardly inclined slopes.

[0016] Preferably, the water-locking mechanism includes multiple water-blocking rings with a toothed cross-section, respectively disposed at both ends of the roller sponge from the inside out.

[0017] Preferably, the water-blocking ring is inclined radially outward towards the roller sponge, forming a water collection trough at the junction of the water-blocking ring and the roller sponge, which is positioned lower than the leak-proof junction surface.

[0018] The present invention also provides a cleaning tool, which includes a cleaning head, a housing and a roller disposed on the housing, and a drive motor for driving the roller to work. The roller includes a roller bracket and a roller sponge covering the outside of the roller bracket. One end of the roller bracket is provided with a cavity and the other end is provided with a telescopic rotating shaft mechanism. Water-locking mechanisms are provided at both ends of the roller sponge to prevent liquid from flowing out during roller cleaning.

[0019] Preferably, the water-locking mechanism includes an inwardly inclined surface at any position between the outer diameter and the inner diameter in the thickness direction of the roller sponge, and forms an annular arc surface in the thickness of the roller sponge.

[0020] Preferably, the annular arc surface of the roller sponge is provided with a water-locking layer with a density greater than that of the roller sponge.

[0021] Preferably, the surface of the water-locking layer is smooth.

[0022] Preferably, the telescopic pivot mechanism includes a pivot fixed at one end to a fixed base that moves only linearly, an elastic component sleeved on the pivot to keep the pivot in an extended state, and a pivot cover covering the end of the pivot. A bearing is provided between the pivot cover and the pivot. When force is applied to the pivot cover, the pivot moves linearly inward. When released, the elastic component causes the pivot and the pivot cover to extend outward.

[0023] Preferably, the water-locking mechanism includes water-blocking rings that protrude from the main body of the roller sponge at both ends of the roller sponge.

[0024] Preferably, the outer side of the water-retaining ring is flush with the outer diameter of the roller sponge.

[0025] Preferably, the inner side of the water-blocking ring is an inclined surface.

[0026] Preferably, the outer side of the water-blocking ring is provided with directional deformation grooves, which are distributed in the circumferential direction of the water-blocking ring.

[0027] Preferably, the cross-section of the directional deformation groove is trapezoidal.

[0028] Preferably, both the inner and outer sides of the water-blocking ring are outwardly inclined slopes.

[0029] Preferably, the water-locking mechanism includes multiple water-blocking rings with a toothed cross-section, respectively disposed at both ends of the roller sponge from the inside out.

[0030] Preferably, the water-blocking ring is inclined radially outward towards the roller sponge, forming a water collection trough at the junction of the water-blocking ring and the roller sponge, which is positioned lower than the leak-proof junction surface.

[0031] This invention relates to a leak-proof cleaning roller and cleaning tool. The leak-proof cleaning roller includes a roller support and a roller sponge covering the outside of the roller support. One end of the roller support has a cavity, and the other end has a telescopic rotating shaft mechanism. Water-locking mechanisms are provided at both ends of the roller sponge to prevent liquid leakage during roller cleaning. Because water-locking mechanisms are provided at both ends of the roller sponge to prevent water leakage from the sides of the roller, these mechanisms reduce friction between the roller sponge and the cleaning head housing, while also improving the water tightness between the roller sponge and the cleaning head housing. Furthermore, this prevents excessive friction from reducing the lifespan of the cleaning roller, improving battery efficiency, and also prevents a decrease in the overall water absorption and moisturizing performance of the roller sponge.

[0032] In addition, the water-locking mechanism reduces the amount of elastic deformation between the end of the sponge layer and the side wall of the cleaning head housing. As the sponge layer dries and hardens, the expansion force on the side wall of the cleaning head housing is naturally reduced, thus improving the lifespan of the cleaning head housing.

[0033] The water-locking mechanism includes an inwardly inclined surface at any position between the outer and inner diameters of the roller sponge along its thickness direction, forming an annular arc surface within the thickness of the roller sponge. This annular arc surface has a water-locking layer with a density greater than that of the roller sponge, and the surface of the water-locking layer is smooth. Because of the smooth surface of the water-locking layer, the friction between it and the housing is reduced after installation, while simultaneously increasing the contact area with the housing, effectively increasing the length of the watertight path, and thus effectively preventing leakage of cleaning liquid.

[0034] The water-locking mechanism employs water-retaining rings protruding from both ends of the roller sponge. Because the water-retaining rings are relatively small, they expand outwards during use, thus increasing the contact area with the housing to a limited extent. With proper design, this prevents a significant increase in contact friction between the two. Simultaneously, when expanding outwards, the contact surface between the roller sponge and the housing is positioned higher than the surface of the roller sponge, preventing the cleaning fluid from flowing to the higher end of the roller sponge during cleaning, effectively reducing liquid leakage. The inner side of the water-retaining ring is sloped, which facilitates its outward expansion when combined with the housing.

[0035] The outer side of the water-retaining ring is provided with directional deformation grooves, which are distributed along the circumference of the water-retaining ring. These grooves ensure that the water-retaining ring expands in a predetermined direction, i.e., outward, when it is fitted with the shell. The trapezoidal cross-section of the directional deformation grooves is also for better guidance of outward expansion.

[0036] As needed, both the inner and outer sides of the water-blocking ring are outwardly inclined slopes, which are intended to ensure that it can expand outwards when it is fitted with the shell, thereby ensuring the water-locking purpose is achieved. Attached Figure Description

[0057] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0058] The following will describe the scheme of this application in detail with reference to the accompanying drawings.

[0059] Figures 1-10 As shown, the present invention provides an embodiment of a water-proof cleaning roller.

[0060] The water-proof cleaning roller 1 includes a roller support 11 and a roller sponge 12 covering the outside of the roller support 11. One end of the roller support 12 is provided with a cavity (not shown in the figure), and the other end is provided with a telescopic rotating shaft mechanism. At both ends of the roller sponge 12, there are water-locking mechanisms to prevent liquid from flowing out during roller cleaning.

[0061] Specifically, the telescopic pivot mechanism includes a pivot 15 fixed at one end to a fixed base 16 and capable of linear movement, an elastic component 14 sleeved on the pivot 15 to keep it in an extended state, and a pivot cover 13 covering the end of the pivot 15. A bearing is provided between the pivot cover and the pivot. When force is applied to the pivot cover, the pivot moves linearly inward; when released, the elastic component causes the pivot and the pivot cover to extend outward. The pivot cover 13 is polygonal, such as square, hexagonal, or other structures capable of transmitting rotational torque. The water-locking mechanism includes an inwardly inclined slope 121 at any position between the outer and inner diameters of the roller sponge 12 in the thickness direction, forming an annular arc surface on the thickness of the roller sponge 12. The annular arc surface of the roller sponge has a water-locking layer 120 with a density greater than that of the roller sponge. The surface of the water-locking layer 120 is smooth. Due to the smooth surface of the water-locking layer, the friction between it and the housing is small after installation, while increasing the contact area with the housing, effectively increasing the length of the watertight path, and thus effectively preventing leakage of cleaning liquid.

[0062] The water-locking mechanism can also include water-retaining rings 10 protruding from both ends of the roller sponge 12. Because the water-retaining rings 10 are small, they expand outwards during use, thus increasing the contact area with the housing to a limited extent. With proper design, this does not lead to a significant increase in contact friction between the two. Simultaneously, when expanding outwards, the contact surface between the roller sponge and the housing is positioned higher than the surface of the roller sponge 12, preventing the cleaning fluid from flowing to the higher end of the roller sponge during cleaning, thereby effectively reducing liquid leakage. The inner side of the water-retaining ring is sloped, which facilitates the outward expansion of the water-retaining ring when it mates with the housing A.

[0063] The outer side of the water-retaining ring 10 is provided with directional deformation grooves 102, which are distributed in the circumferential direction of the water-retaining ring. The directional deformation grooves can ensure that the water-retaining ring expands in a preset direction when it is fitted with the shell, that is, it expands outward. The trapezoidal cross-section of the directional deformation groove is also for better guidance of outward expansion.

[0064] As needed, both the inner and outer sides of the water-blocking ring 10 are outwardly inclined slopes 101, which are intended to ensure that it can expand outwards when it is fitted with the shell, thereby ensuring that the purpose of water locking is achieved.

[0065] like Figures 9-10 As shown, the water-locking mechanism can also be implemented using the following structure: The water-locking mechanism includes multiple water-blocking rings 10 respectively disposed at both ends of the roller sponge 12, arranged from the inside out. The multiple water-blocking rings 10 are located between the inner and outer radial diameters of the roller sponge 12, and may not include the inner and outer diameters. The multiple water-blocking rings 10 have a toothed cross-section. The multiple water-blocking rings 10 are optimally positioned radially outwards from the roller sponge 12. Because multiple water-blocking rings 10 are provided and are inclined outwards, it ensures that after installation, the water-blocking rings 10 can form a relatively large contact surface with the housing. Furthermore, the bottom of the water-blocking ring 10 forms a water collection groove 103 at the junction with the roller sponge 12, positioned lower than the leak-proof junction surface, thus achieving a better leak-proof effect. The leak-proof junction surface refers to the contact surface formed between the water-blocking ring 10 and the housing. Simultaneously, the multiple elastically deformable water-blocking rings work together to achieve multiple water-locking between the ends of the roller sponge and the sidewalls of the cleaning head housing. Even if some water-blocking rings are damaged, as long as one water-blocking ring remains intact, the water-locking function at both ends of the roller sponge can still be achieved. Even if multiple water-blocking rings are partially damaged or all water-blocking rings are partially damaged, as long as the damage is not a straight-through damage radiating outward from the axis (the damage is irregular and will be blocked by the second or third partially damaged water-blocking rings), the ends of the roller sponge can still maintain a certain water-locking capacity under the action of centrifugal force, thus improving the durability of the sponge roller.

[0066] Because water-locking mechanisms are installed at both ends of the roller sponge to prevent water leakage from the sides of the roller, these mechanisms reduce friction between the sponge and the cleaning head housing, while also improving the water tightness between the roller sponge and the cleaning head housing. This also prevents excessive friction from reducing the lifespan of the cleaning roller, improving battery efficiency, and preventing a decline in the overall water absorption and moisturizing performance of the roller sponge.

[0067] In addition, the water-locking mechanism reduces the amount of elastic deformation between the end of the sponge layer and the side wall of the cleaning head housing. As the sponge layer dries and hardens, the expansion force on the side wall of the cleaning head housing is naturally reduced, thus improving the lifespan of the cleaning head housing.

[0068] Figures 1-12As shown, the present invention also provides an embodiment of a cleaning tool.

[0069] The cleaning tool includes a cleaning head, which includes a housing and a roller disposed on the housing, as well as a drive motor for driving the roller. The roller includes a roller bracket and a roller sponge covering the outside of the roller bracket. One end of the roller bracket is provided with a cavity, and the other end is provided with a telescopic rotating shaft mechanism. At both ends of the roller sponge, there are water-locking mechanisms to prevent liquid from flowing out during roller cleaning.

[0070] Specifically, the roller support 11 has a cavity and a drive motor 2 at one end. One end of the drive motor 2 is connected to the housing via a universal joint B, and the other end is connected to the rotating shaft 15 via a shaft connector 21. The rotating shaft 15 drives the roller support 11 and the roller sponge 12 to rotate.

[0071] The telescopic rotating shaft mechanism includes a rotating shaft 15 fixed at one end to a fixed base 16 and capable of linear movement, an elastic component 14 sleeved on the rotating shaft 15 to keep it in an extended state, and a rotating shaft cover 13 covering the end of the rotating shaft 15. A bearing is provided between the rotating shaft cover and the rotating shaft. When force is applied to the rotating shaft cover, the rotating shaft moves linearly inward; when released, the elastic component causes the rotating shaft and the rotating shaft cover to extend outward. The rotating shaft cover 13 is polygonal, such as square, hexagonal, or other structures capable of transmitting rotational torque. The water-locking mechanism includes an inwardly inclined slope 121 at any position between the outer and inner diameters of the roller sponge 12 in the thickness direction, forming an annular arc surface on the thickness of the roller sponge 12. The annular arc surface of the roller sponge has a water-locking layer 120 with a density greater than that of the roller sponge. The surface of the water-locking layer 120 is smooth. Due to the smooth surface of the water-locking layer, the friction between it and the housing is small after installation, while increasing the contact area with the housing, effectively increasing the length of the watertight path, and thus effectively preventing leakage of cleaning liquid.

[0072] The water-locking mechanism can also include water-retaining rings 10 protruding from both ends of the roller sponge 12. Because the water-retaining rings 10 are small, they expand outwards during use, thus increasing the contact area with the housing to a limited extent. With proper design, this does not lead to a significant increase in contact friction between the two. Simultaneously, when expanding outwards, the contact surface between the roller sponge and the housing is positioned higher than the surface of the roller sponge 12, preventing the cleaning fluid from flowing to the higher end of the roller sponge during cleaning, thereby effectively reducing liquid leakage. The inner side of the water-retaining ring is sloped, which facilitates the outward expansion of the water-retaining ring when it mates with the housing A.

[0073] The outer side of the water-retaining ring 10 is provided with directional deformation grooves 102, which are distributed in the circumferential direction of the water-retaining ring. The directional deformation grooves can ensure that the water-retaining ring expands in a preset direction when it is fitted with the shell, that is, it expands outward. The trapezoidal cross-section of the directional deformation groove is also for better guidance of outward expansion.

[0074] As needed, both the inner and outer sides of the water-blocking ring 10 are outwardly inclined slopes 101, which are intended to ensure that it can expand outwards when it is fitted with the shell, thereby ensuring that the purpose of water locking is achieved.

[0075] like Figures 9-10 As shown, the water-locking mechanism can also be implemented using the following structure: The water-locking mechanism includes multiple water-blocking rings 10 respectively disposed at both ends of the roller sponge 12, arranged from the inside out. The multiple water-blocking rings 10 are located between the inner and outer radial diameters of the roller sponge 12, and may not include the inner and outer diameters. The multiple water-blocking rings 10 have a toothed cross-section. The multiple water-blocking rings 10 are optimally positioned radially outwards from the roller sponge 12. Because multiple water-blocking rings 10 are provided and are inclined outwards, it ensures that after installation, the water-blocking rings 10 can form a relatively large contact surface with the housing. Furthermore, the bottom of the water-blocking ring 10 forms a water collection groove 103 at the junction with the roller sponge 12, positioned lower than the leak-proof junction surface, thus achieving a better leak-proof effect. The leak-proof junction surface refers to the contact surface formed between the water-blocking ring 10 and the housing. Simultaneously, the multiple elastically deformable water-blocking rings work together to achieve multiple water-locking between the ends of the roller sponge and the sidewalls of the cleaning head housing. Even if some water-blocking rings are damaged, as long as one water-blocking ring remains intact, the water-locking function at both ends of the roller sponge can still be achieved. Even if multiple water-blocking rings are partially damaged or all water-blocking rings are partially damaged, as long as the damage is not a straight-through damage radiating outward from the axis (the damage is irregular and will be blocked by the second or third partially damaged water-blocking rings), the ends of the roller sponge can still maintain a certain water-locking capacity under the action of centrifugal force, thus improving the durability of the sponge roller.

[0076] Because water-locking mechanisms are installed at both ends of the roller sponge to prevent water leakage from the sides of the roller, these mechanisms reduce friction between the sponge and the cleaning head housing, while also improving the water tightness between the roller sponge and the cleaning head housing. This also prevents excessive friction from reducing the lifespan of the cleaning roller, improving battery efficiency, and preventing a decline in the overall water absorption and moisturizing performance of the roller sponge.

[0077] In addition, the water-locking mechanism reduces the amount of elastic deformation between the end of the sponge layer and the side wall of the cleaning head housing. As the sponge layer dries and hardens, the expansion force on the side wall of the cleaning head housing is naturally reduced, thus improving the lifespan of the cleaning head housing.

[0078] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. Furthermore, any changes or modifications made by those skilled in the art based on the ideas of this application, and on the specific implementation methods and application scope of this application, are all within the scope of protection of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
