Description

Technical Field

[0001] This invention belongs to the field of cleaning tool technology, and in particular relates to a dual-roller linkage high-efficiency cleaning sticky roller device. Background Technology

[0002] This invention belongs to the field of cleaning tool technology, specifically relating to an adhesive roller cleaning device that can be widely used for cleaning dust, hair, debris and other debris on desktops, floors, clothing, electronic device surfaces, etc., and is suitable for various environments such as homes, offices, and workshops.

[0003] Currently, most adhesive rollers on the market for cleaning surface debris are single-roller structures. Their core principle is based on adhesive paper wrapped around the roller surface. By rolling, the paper adheres to the surface to be cleaned, relying on its stickiness to attract dust, hair, and other debris, thus achieving a cleaning function. These adhesive rollers are simple in structure, easy to carry, and widely used in home cleaning and office tidying. They can quickly remove small debris and are more effective at cleaning lint, hair, and crumbs compared to brooms and rags.

[0004] Existing single-roller adhesive cleaning devices have significant technical defects and cannot meet the needs of efficient and hygienic cleaning, as follows: 1. Low cleaning efficiency: In the existing device, every time the roller rotates once and the surface adhesive paper is full of debris, the used adhesive paper must be manually peeled off in order to expose the unused adhesive paper underneath to continue cleaning. The frequent shutdown and paper peeling operations greatly interrupt the cleaning process, resulting in extremely low overall cleaning efficiency. This problem is even more prominent in large-area cleaning scenarios.

[0005] 2. May cause secondary contamination of hands: When manually tearing off used sticky paper, the user's hands need to come into direct contact with the waste paper that has absorbed debris and dust, which can easily lead to hand contamination. In addition, if the debris contains fine dust or sharp fragments, it may also cause minor damage to the skin, affecting the hygiene and safety of use.

[0006] The aforementioned defects are inherent problems caused by the existing single-roller adhesive roller structure design, and there is no effective solution in the existing technology, which restricts the user experience and the expansion of applicable scenarios of adhesive cleaning tools. Summary of the Invention

[0007] The purpose of this invention application is to provide a dual-roller linkage high-efficiency cleaning adhesive roller device, which achieves simultaneous cleaning and waste paper recycling through structural optimization, eliminating the need for frequent machine shutdowns to clean waste paper, thereby significantly improving cleaning efficiency, avoiding contamination caused by hand contact with waste paper, optimizing the user experience, and meeting the needs for efficient and hygienic cleaning in different scenarios.

[0008] This invention application provides a dual-roller linkage high-efficiency cleaning adhesive roller device, including a housing and a hand handle. The housing is provided with roller mounting holes. The housing is also provided with an inertial synchronization device. Two sets of cleaning rollers are installed in parallel on both sides of the inertial synchronization device through the roller mounting holes. The inertial synchronization device acts on both sets of cleaning rollers at the same time and realizes that the transmission ratio of the outer circumference lengths of the two sets of cleaning rollers is maintained at 1:1.

[0009] Furthermore, the inertial synchronization device is equipped with an inertial synchronization wheel. The outer surface of the inertial synchronization wheel is in close contact with the outer surfaces of the two sets of cleaning rollers. The transmission ratio of the outer circumference lengths of the two sets of cleaning rollers is maintained at 1:1 by friction between the inertial synchronization wheel and the two sets of cleaning rollers.

[0010] Furthermore, the inertial synchronization device includes an inertial synchronization wheel and an elastic device.

[0011] Furthermore, the inertial synchronization device includes a spring plate bracket with a compression spring plate inside, an elastic adjustment bracket movably mounted above the spring plate bracket, and a rotatable inertial synchronization wheel mounted on the elastic adjustment bracket.

[0012] Furthermore, the elastic adjustment bracket is hinged to the spring plate bracket, allowing it to swing slightly left and right; the upper part of the compression spring plate contacts the bottom of the elastic adjustment bracket, and the two provide a constant preload by applying pressure to each other; the outer surface of the inertial synchronous wheel is in close contact with the outer surfaces of the active cleaning roller and the driven recovery roller.

[0013] Furthermore, the housing is provided with an inertial device bracket, on which an inertial synchronization device is fixedly installed.

[0014] Furthermore, the two sets of cleaning rollers include an active cleaning roller and a passive recovery roller. The active cleaning roller is located at the outer end of the housing to facilitate rolling contact with the surface to be cleaned.

[0015] Furthermore, roller shafts are installed on both outer ends of the active cleaning roller and the driven recovery roller.

[0016] Furthermore, the active cleaning roller is wrapped with a roll of sticky paper for cleaning, and the driven recovery roller is used to recover the used sticky paper roll.

[0017] Furthermore, the active cleaning roller and the passive recovery roller have the same size specifications.

[0018] Furthermore, the inertial synchronizing pulley uses a high-strength core material, and its outer surface is wrapped with a certain thickness of high-friction material; the high-friction material can be a layer of nitrile rubber, silicone, or polyurethane.

[0019] Furthermore, the preload of the elastic adjustment bracket can be adjusted to a range of 3-10N by adjusting the spring specifications to accommodate adhesive paper rolls of different thicknesses.

[0020] The core innovation of this invention lies in the dual-roller linkage + pure inertial synchronous wheel friction transmission structure, which eliminates traditional gears, synchronous belts, and other transmission components, resulting in a simpler and more reliable structure. On the one hand, the dual rollers achieve simultaneous cleaning and waste paper recycling, eliminating the need for manual tearing of waste paper; on the other hand, the inertial synchronous wheel is pressed between the two rollers by an elastic adjustment bracket, transmitting power solely through the friction of the contact surface. The elastic adjustment bracket and compression spring can adapt in real time to the size changes of the active cleaning roller (whose diameter decreases after paper roll consumption) and the driven recycling roller (whose diameter increases after paper roll winding), automatically fine-tuning the position of the inertial synchronous wheel to maintain constant contact pressure, eliminating transmission slippage and synchronization deviation caused by diameter changes, ensuring that the rotation speed of the two rollers is always consistent, avoiding the tearing or uneven winding of sticky paper, and balancing efficiency, hygiene, and dynamic stability.

[0021] During use, the overall diameter of the active cleaning roller and the driven recovery roller dynamically changes due to the continuous use and recycling of the adhesive paper roll. Through an intermediate inertial synchronizing wheel, the outer circumferential rolling length between the two sets of cleaning rollers is always kept synchronized. That is, the outer circumference of the active cleaning roller is transmitted to the driven recovery roller via the inertial synchronizing wheel, achieving real-time synchronization. This solves the problem that, although gears or timing belts can force the two rollers to rotate at the same speed, the different diameters can cause uneven circumferences in the two rollers per revolution, resulting in the adhesive paper roll being too loose or too tight. This truly achieves complete synchronization between the active cleaning roller and the driven recovery roller.

[0022] The beneficial effects of this invention application are as follows: 1. Significantly improved cleaning efficiency: The dual rollers work in sync, with cleaning and waste paper recycling completed simultaneously. Users only need to push the device to keep the active cleaning rollers rolling to continue cleaning without having to stop the machine to remove waste paper. Actual tests show that cleaning time for the same area (1㎡) is reduced by more than 80-90% compared to existing single roller devices. The larger the area, the more obvious the effect, making it especially suitable for large-area cleaning scenarios.

[0023] 2. Eliminate secondary hand contamination: Used sticky paper is automatically wound and recycled by a driven recycling roller, eliminating the need for hand contact with waste paper throughout the process. This completely solves the problem of hand contamination during the cleaning process of existing devices, improving hygiene and safety.

[0024] 3. Improved ease of operation: The device has a compact structure and an ergonomically designed hand grip. Users do not need to perform any additional operations; they can achieve continuous cleaning simply by pushing the handle. This reduces the difficulty of operation and enhances the user experience. 4. Strong and simplified structure: Utilizing pure inertial synchronous pulley friction transmission, it eliminates easily worn transmission components such as gears and timing belts, resulting in a simpler structure and lower failure rate. The pure friction transmission structure is extremely simple, with no easily worn transmission components, ensuring strong stability and a low failure rate, thus reducing production and maintenance costs. The inertial synchronous pulley adapts to the dynamic diameter changes of the dual rollers through an elastic bracket, maintaining a stable fit and a 1:1 transmission ratio at all times. This completely solves the problems of synchronization deviation, paper jams, and paper breakage caused by changes in roller diameter, extending the service life by more than 50% compared to traditional transmission structures.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] The specific implementation of the present invention will be described in detail below with reference to specific embodiments. Example

[0028] like Figure 1-3 As shown, this embodiment provides a dual-roller linkage type high-efficiency cleaning adhesive roller device, including a housing 1 and a handheld handle 5. The housing 1 is provided with roller mounting holes 7. The housing 1 is also provided with an inertial synchronization device. Two sets of cleaning rollers are installed in parallel on both sides of the inertial synchronization device through the roller mounting holes 7. The inertial synchronization device acts on both sets of cleaning rollers simultaneously, and maintains a 1:1 transmission ratio of the outer circumference lengths of the two sets of cleaning rollers. The inertial synchronization device is provided with an inertial synchronization wheel 8. The outer surface of the inertial synchronization wheel 8 is in close contact with the outer surfaces of both sets of cleaning rollers. The friction between the inertial synchronization wheel 8 and the two sets of cleaning rollers maintains a 1:1 transmission ratio of the outer circumference lengths of the two sets of cleaning rollers.

[0029] like Figure 4-5 As shown, the inertial synchronization device includes an inertial synchronization wheel 8 and an elastic device. The inertial synchronization device includes a spring plate bracket 12, which houses a compression spring plate 10. An elastic adjustment bracket 9 is movably mounted above the spring plate bracket 12, and a rotatable inertial synchronization wheel 8 is mounted on the elastic adjustment bracket 9. The elastic adjustment bracket 9 is hinged to the spring plate bracket 12 and can swing slightly left and right. The compression spring plate 10 contacts the bottom of the elastic adjustment bracket 9, and the two provide a constant preload through mutual pressure. The outer surface of the inertial synchronization wheel 8 is in close contact with the outer surfaces of both the active cleaning roller 2 and the driven recovery roller 3.

[0030] The housing 1 is provided with an inertial device bracket 11, and an inertial synchronization device is fixedly installed on the inertial device bracket 11.

[0031] The two sets of cleaning rollers include an active cleaning roller 2 and a driven recovery roller 3. The active cleaning roller 2 is located at the outer end of the housing 1 for easy rolling contact with the surface to be cleaned. Roller shafts 6 are installed on both outer ends of the active cleaning roller 2 and the driven recovery roller 3. An adhesive paper roll 4 for cleaning is wound around the outside of the active cleaning roller 2, and the driven recovery roller 3 is used to collect the used adhesive paper roll 4. The active cleaning roller 2 and the driven recovery roller 3 have the same dimensions.

[0032] The inertial synchronizing pulley 8 uses a high-strength core material, and its outer surface is wrapped with a certain thickness of high-friction material; the high-friction material can be nitrile rubber, silicone, or polyurethane. The preload of the elastic adjustment bracket 9 can be adjusted to a range of 3-10N by adjusting the spring specifications to accommodate adhesive paper rolls 4 of different thicknesses.

[0033] The housing 1 is made of high-strength ABS plastic and has two parallel roller mounting slots inside, which are used to assemble the active cleaning roller and the passive recovery roller, respectively. A hand handle is provided on the rear side of the housing for easy operation and movement of the device.

[0034] The active cleaning roller 2 and the driven recycling roller 3 are identical in specifications, both made of the same material with a core diameter of 10-100mm and a length of 40-300mm. The surface is smooth to ensure the adhesion of the adhesive paper. The active cleaning roller is mounted on the lower part of the housing near the surface to be cleaned. Its core ends are rotatably connected to the housing, and part of the roller surface is exposed on the bottom of the housing for contact with the surface to be cleaned. The driven recycling roller is mounted on the upper inner side of the housing and arranged parallel to the active cleaning roller. It is used to recycle the used adhesive paper roll 4.

[0035] The overall transmission structure adds an inertial synchronous wheel 8 between the active cleaning roller 2 and the driven recovery roller 3. The inertial synchronous wheel 8 is assembled in the housing through an elastic adjustment bracket 9. The elastic adjustment bracket 9 provides a constant preload, so that the outer surface of the inertial synchronous wheel 8 is in close contact with the outer surfaces of both the active cleaning roller 2 and the driven recovery roller 3. This allows the friction between the inertial synchronous wheel 8 and the two rollers to transmit power, maintaining an overall transmission ratio of 1:1. Furthermore, the elastic adjustment bracket 9 can adaptively fine-tune the position of the inertial synchronous wheel 8 according to the dynamic diameter changes of the two rollers, always maintaining a close contact state. This achieves dynamic synchronous forward and reverse rotation of the two rollers, completely solving the synchronization deviation problem caused by changes in roller diameter due to paper roll winding during use.

[0036] The adhesive paper roll 4 uses existing general-purpose adhesive cleaning paper, which is initially wrapped around the surface of the active cleaning roller. The free end of the paper is pulled to the driven recovery roller and fixed, so that the adhesive paper forms a taut conveying surface between the two rollers.

[0037] The core innovation of this embodiment lies in the dual-roller linkage + pure inertial synchronous wheel friction transmission structure, which eliminates traditional gears, synchronous belts and other transmission components, resulting in a simpler and more reliable structure. On the one hand, the dual rollers achieve simultaneous cleaning and waste paper recycling, eliminating the need for manual tearing of waste paper; on the other hand, the inertial synchronous wheel 8 is pressed between the two rollers by the elastic adjustment bracket 9, transmitting power solely through the friction of the contact surface. The elastic adjustment bracket 9 and the compression spring plate 10 can adapt in real time to the size changes of the active cleaning roller 2 (whose diameter decreases after paper roll consumption) and the driven recycling roller 3 (whose diameter increases after paper roll winding), automatically fine-tuning the position of the inertial synchronous wheel 8 to maintain a constant bonding pressure, eliminating transmission slippage and synchronization deviation caused by diameter changes, ensuring that the rotation speed of the two rollers is always consistent, avoiding the tearing or uneven winding of sticky paper, and balancing efficiency, hygiene and dynamic stability.

[0038] During use, the overall diameter of the active cleaning roller 2 and the driven recovery roller 3 dynamically changes due to the continuous use and recycling of the adhesive paper roll. Through the intermediate inertial synchronizing wheel 8, the outer circumferential rolling length between the two sets of cleaning rollers is always kept synchronized. That is, the outer circumference of the active cleaning roller 2 is transmitted to the driven recovery roller 3 via the inertial synchronizing wheel, achieving real-time synchronization. This solves the problem that although gears or timing belts can force the two rollers to rotate at the same speed, differences in diameter can cause inconsistent circumferences in the two rollers per revolution, resulting in the adhesive paper roll being too loose or too tight. It truly achieves complete synchronization between the active cleaning roller and the driven recovery roller. Example

[0039] like Figure 1-3As shown, this embodiment provides a dual-roller linkage type high-efficiency cleaning adhesive roller device, including a housing 1 and a handheld handle 5. The housing 1 is provided with roller mounting holes 7. The housing 1 is also provided with an inertial synchronization device. Two sets of cleaning rollers are installed in parallel on both sides of the inertial synchronization device through the roller mounting holes 7. The inertial synchronization device acts on both sets of cleaning rollers simultaneously, and maintains a 1:1 transmission ratio of the outer circumference lengths of the two sets of cleaning rollers. The inertial synchronization device is provided with an inertial synchronization wheel 8. The outer surface of the inertial synchronization wheel 8 is in close contact with the outer surfaces of both sets of cleaning rollers. The friction between the inertial synchronization wheel 8 and the two sets of cleaning rollers maintains a 1:1 transmission ratio of the outer circumference lengths of the two sets of cleaning rollers.

[0040] like Figure 4-5 As shown, the inertial synchronization device includes an inertial synchronization wheel 8 and an elastic device. The elastic device includes a spring plate bracket 12, a compression spring plate 10, and an elastic adjustment bracket 9. The compression spring plate 10 is housed inside the spring plate bracket 12, and the elastic adjustment bracket 9 is movably mounted above the spring plate bracket 12. A rotatable inertial synchronization wheel 8 is mounted on the elastic adjustment bracket 9. The elastic adjustment bracket 9 is hinged to the spring plate bracket 12 and can swing left and right with a small amplitude. The compression spring plate 10 contacts the bottom of the elastic adjustment bracket 9, and the two provide a constant preload by applying pressure to each other. The outer surface of the inertial synchronization wheel 8 is in close contact with the outer surfaces of both the active cleaning roller 2 and the driven recovery roller 3.

[0041] The housing 1 is provided with an inertial device bracket 11, and an inertial synchronization device is fixedly installed on the inertial device bracket 11.

[0042] The two sets of cleaning rollers include an active cleaning roller 2 and a driven recovery roller 3. The active cleaning roller 2 is located at the outer end of the housing 1 for easy rolling contact with the surface to be cleaned. Roller shafts 6 are installed on both outer ends of the active cleaning roller 2 and the driven recovery roller 3. An adhesive paper roll 4 for cleaning is wound around the outside of the active cleaning roller 2, and the driven recovery roller 3 is used to collect the used adhesive paper roll 4. The active cleaning roller 2 and the driven recovery roller 3 have the same dimensions.

[0043] The inertial synchronizing pulley 8 uses a high-strength core material, and its outer surface is wrapped with a certain thickness of high-friction material; the high-friction material is made of nitrile rubber. The preload of the elastic adjustment bracket 9 can be adjusted to 5N by adjusting the spring specifications.

[0044] Housing: Made of ABS engineering plastic injection molding, with overall dimensions of 240mm×110mm×50mm. A rectangular opening (110mm long and 50mm wide) is provided at the bottom of the housing to expose the surface of the active cleaning roller. The rear of the housing has an integrated hand grip with anti-slip texture. The grip is 100mm long and 30mm in diameter. Two parallel roller mounting slots are provided on the inner side of the housing, with a slot spacing of 60mm. The mounting slots have circular holes for mounting the roller core. Active cleaning roller (outer diameter 50mm including adhesive roll paper) and driven recovery roller (outer diameter 40mm): The core is made of the same material, the core diameter is 40mm, the length is 100mm, and there are rotating shafts at both ends of the core. The rotating shafts have a diameter of 15mm and cooperate with the circular holes of the mounting groove inside the housing to achieve rotation. Transmission Structure: Utilizing pure inertial synchronous wheel friction transmission, without any gears or synchronous belts. The inertial wheel has a nylon core with a 1mm thick nitrile rubber layer on its outer surface (to improve the coefficient of friction and wear resistance). The inertial wheel has a diameter of 15mm and a width consistent with the two rollers (20mm). The inertial wheel is mounted on a stainless steel elastic adjustment bracket, which is connected to the housing via a sliding guide rail. The adjustment stroke is 0-10mm. A built-in compression spring in the bracket provides a constant preload of 5N, ensuring the outer surface of the inertial wheel remains in close contact with the surfaces of the two rollers. Dynamic synchronous reverse rotation is achieved through friction, with no transmission deviation. Adhesive paper roll: Select adhesive cleaning paper with a thickness of 0.15mm, a width of 100mm, and a length of 10m. Initially, it is tightly wound around the surface of the active cleaning roller. The free end of the paper is fixed to the core of the driven recovery roller with self-adhesive. The winding tension is controlled at 5N to ensure that the paper is taut and will not be torn.

[0045] The working process of this embodiment is as follows: The user holds the handle of the casing and places the active cleaning roller at the bottom of the device against the surface to be cleaned (such as a desktop, floor, clothing, electronic devices, etc.). Pushing the device forward causes the active cleaning roller to rotate clockwise under friction. This friction with the inertial wheel drives the inertial wheel to rotate, which in turn drives the driven recovery roller to rotate counterclockwise synchronously. During the cleaning process, the diameter of the active cleaning roller gradually decreases from 50mm to 40mm due to the consumption of the sticky paper roll, while the diameter of the driven recovery roller gradually increases from 40mm to 50mm due to the entanglement of the waste paper roll. At this time, the idler wheel adaptively fine-tunes its position along the guide rail via the elastic adjustment bracket, and under the pre-pressure of the compression spring, it always keeps in close contact with the surfaces of the two rollers to ensure synchronized rotation speed. The sticky paper on the surface of the active cleaning roller adsorbs dust, hair, and other debris from the surface to be cleaned during the rolling process, and is simultaneously wound and recycled by the driven recovery roller. The surface of the active cleaning roller automatically exposes the next layer of new sticky paper, maintaining its cleaning ability. When all the sticky paper rolls on the surface of the active cleaning roller are used up, the waste paper rolls on the driven recovery roller are removed, replaced with new sticky paper rolls, and the fixing process is repeated for reuse. According to the test, the device of this embodiment takes only 1 minute to clean 1㎡ of floor, which is 80% more efficient than the existing single roller device (5 minutes). There is no hand contact with waste paper throughout the process, and there is no synchronization deviation, paper jam, or paper breakage throughout the entire consumption cycle of the paper roll. It has excellent dynamic stability and no gear transmission noise, resulting in a better user experience. Example

[0046] like Figure 1-3 As shown, this embodiment provides a dual-roller linkage type high-efficiency cleaning adhesive roller device, including a housing 1 and a handheld handle 5. The housing 1 is provided with roller mounting holes 7. The housing 1 is also provided with an inertial synchronization device. Two sets of cleaning rollers are installed in parallel on both sides of the inertial synchronization device through the roller mounting holes 7. The inertial synchronization device acts on both sets of cleaning rollers simultaneously, and maintains a 1:1 transmission ratio of the outer circumference lengths of the two sets of cleaning rollers. The inertial synchronization device is provided with an inertial synchronization wheel 8. The outer surface of the inertial synchronization wheel 8 is in close contact with the outer surfaces of both sets of cleaning rollers. The friction between the inertial synchronization wheel 8 and the two sets of cleaning rollers maintains a 1:1 transmission ratio of the outer circumference lengths of the two sets of cleaning rollers.

[0047] like Figure 4-5As shown, the inertial synchronization device includes an inertial synchronization wheel 8 and an elastic device. The elastic device includes a spring plate bracket 12, a compression spring plate 10, and an elastic adjustment bracket 9. The compression spring plate 10 is housed inside the spring plate bracket 12, and the elastic adjustment bracket 9 is movably mounted above the spring plate bracket 12. A rotatable inertial synchronization wheel 8 is mounted on the elastic adjustment bracket 9. The elastic adjustment bracket 9 is hinged to the spring plate bracket 12 and can swing left and right with a small amplitude. The compression spring plate 10 contacts the bottom of the elastic adjustment bracket 9, and the two provide a constant preload by applying pressure to each other. The outer surface of the inertial synchronization wheel 8 is in close contact with the outer surfaces of both the active cleaning roller 2 and the driven recovery roller 3.

[0048] The housing 1 is provided with an inertial device bracket 11, and an inertial synchronization device is fixedly installed on the inertial device bracket 11.

[0049] The two sets of cleaning rollers include an active cleaning roller 2 and a driven recovery roller 3. The active cleaning roller 2 is located at the outer end of the housing 1 for easy rolling contact with the surface to be cleaned. Roller shafts 6 are installed on both outer ends of the active cleaning roller 2 and the driven recovery roller 3. An adhesive paper roll 4 for cleaning is wound around the outside of the active cleaning roller 2, and the driven recovery roller 3 is used to collect the used adhesive paper roll 4. The active cleaning roller 2 and the driven recovery roller 3 have the same dimensions.

[0050] The inertial synchronizing pulley 8 uses a high-strength core material, and its outer surface is wrapped with a certain thickness of high-friction material; the high-friction material is made of silicone. The preload of the elastic adjustment bracket 9 can be adjusted to the range of 8N by adjusting the spring specifications.

[0051] Housing: Made of ABS engineering plastic injection molding, with overall dimensions of 240mm×110mm×50mm. A rectangular opening (110mm long and 50mm wide) is provided at the bottom of the housing to expose the surface of the active cleaning roller. The rear of the housing has an integrated hand grip with anti-slip texture. The grip is 100mm long and 30mm in diameter. Two parallel roller mounting slots are provided on the inner side of the housing, with a slot spacing of 60mm. The mounting slots have circular holes for mounting the roller core. Active cleaning roller (outer diameter 50mm including adhesive roll paper) and driven recovery roller (outer diameter 40mm): The core is made of the same material, the core diameter is 40mm, the length is 100mm, and there are rotating shafts at both ends of the core. The rotating shafts have a diameter of 15mm and cooperate with the circular holes of the mounting groove inside the housing to achieve rotation. Transmission Structure: Utilizing pure inertial synchronous wheel friction transmission, without any gears or synchronous belts. The inertial wheel has a nylon core, with its outer surface covered in 1.2mm thick silicone (for quiet operation). The inertial wheel has a diameter of 15mm and a width matching the two rollers (20mm). It is mounted on a stainless steel elastic adjustment bracket, which is connected to the housing via a sliding guide rail. The adjustment range is 0-10mm. A built-in compression spring provides a constant preload of 8N, ensuring the outer surface of the inertial wheel remains in close contact with the surfaces of the two rollers. Dynamic synchronous reverse rotation is achieved through friction, eliminating transmission deviation. Adhesive paper roll: Select adhesive cleaning paper with a thickness of 0.16mm, a width of 100mm, and a length of 10m. Initially, it is tightly wound around the surface of the active cleaning roller. The free end of the paper is fixed to the core of the driven recovery roller with self-adhesive. The winding tension is controlled at 6N to ensure that the paper is taut and will not be torn.

[0052] The working process of this embodiment is as follows: The user holds the handle of the casing and places the active cleaning roller at the bottom of the device against the surface to be cleaned (such as a desktop, floor, clothing, electronic devices, etc.). Pushing the device forward causes the active cleaning roller to rotate clockwise under friction. This friction with the inertial wheel drives the inertial wheel to rotate, which in turn drives the driven recovery roller to rotate counterclockwise synchronously. During the cleaning process, the diameter of the active cleaning roller gradually decreases from 50mm to 40mm due to the consumption of the sticky paper roll, while the diameter of the driven recovery roller gradually increases from 40mm to 50mm due to the entanglement of the waste paper roll. At this time, the idler wheel adaptively fine-tunes its position along the guide rail via the elastic adjustment bracket, and under the pre-pressure of the compression spring, it always keeps in close contact with the surfaces of the two rollers to ensure synchronized rotation speed. The sticky paper on the surface of the active cleaning roller adsorbs dust, hair, and other debris from the surface to be cleaned during the rolling process, and is simultaneously wound and recycled by the driven recovery roller. The surface of the active cleaning roller automatically exposes the next layer of new sticky paper, maintaining its cleaning ability. When all the sticky paper rolls on the surface of the active cleaning roller are used up, the waste paper rolls on the driven recovery roller are removed, replaced with new sticky paper rolls, and the fixing process is repeated for reuse. According to the test, the device of this embodiment takes only 1 minute to clean 1㎡ of floor, which is 80% more efficient than the existing single roller device (5 minutes). There is no hand contact with waste paper throughout the process, and there is no synchronization deviation, paper jam, or paper breakage throughout the entire consumption cycle of the paper roll. It has excellent dynamic stability and no gear transmission noise, resulting in a better user experience.

[0053] This application allows for the selection of different materials for the inertial synchronous roller 8 depending on the specific scenario. For example, silicone can be used for low-noise scenarios, while polyurethane can be used for high wear resistance requirements. The preload of the elastic bracket can be adjusted by adjusting the spring specifications (range 3-10N) to accommodate adhesive paper rolls of different thicknesses. The roller size can be adjusted according to actual needs, such as a miniaturized design (50mm roller diameter, 100mm length) for cleaning clothing and electronic device surfaces, and a larger design (100mm roller diameter, 400mm length) for cleaning workshop floors.

[0054] The inertial synchronization device, a core component of this application, can also be replaced by a gear + damping shaft (the working principle of correction tape), or by using a one-way ratchet to achieve simultaneous rotation of the driving wheel and the driven wheel of the adhesive paper roll to achieve linkage between the two rollers. Both of these solutions, including but not limited to those that can simultaneously act on two sets of cleaning rollers and maintain a 1:1 transmission ratio of the outer circumference lengths of the two sets of cleaning rollers, fall within the protection scope of this application.

[0055] The device proposed in this application has a simple structure, and its core components are all existing mature parts. The production cost is comparable to that of existing single-roller devices, while the user experience is significantly improved. It can be quickly industrialized and is suitable for multiple scenarios such as home, office, and industry, with broad market prospects.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
