Description

Technical Field

[0001] This utility model relates to a cleaning tool, and more particularly to a rolling cleaning tool for quickly removing hair, dust, debris and other debris from the surfaces of clothing, furniture, bedding and other items. It is applied in the fields of green dry cleaning tools and portable cleaning technology. Background Technology

[0002] Lint rollers use mechanical adhesion or electrostatic adsorption on sticky surfaces to quickly remove hair, dust, and small debris from clothing, furniture, carpets, and other surfaces. For example, pet owners can easily remove pet hair, avoiding the embarrassment of fabrics covered in loose fur. Regular use of lint rollers keeps clothes, chairs, carpets, and other items clean, preventing hair buildup and bacterial growth. It also reduces lint pilling caused by friction, extending the lifespan of clothing. Lint rollers are simple to use; just roll or brush them back and forth on the surface to clean, without the need for washing water or complicated tools like vacuum cleaners.

[0003] Most lint rollers support replaceable sticky paper rollers, eliminating the need to replace the entire lint roller and avoiding frequent purchases of disposable cleaning products. Lint rollers can be used not only for cleaning clothes but also for removing dirt from furniture, car seats, curtains, and other surfaces. They are also suitable for cleaning large areas such as sofas and carpets. Lint rollers consist of a replaceable paper roller covered with an adhesive layer, usually made of adhesive glue or special adhesive materials. The adhesive layer is evenly coated on the surface of the roller or sticky paper to ensure maximum contact area and improve adhesion efficiency. These substances have strong adsorption properties and can bind to tiny particles such as hair and dust through intermolecular forces (van der Waals forces) or chemical bonds. When the lint roller rolls or wipes the surface of clothes, furniture, etc., the adhesive layer makes full contact with the target object, and the pressure forces hair, dust, etc., into the adhesive layer. As the paper roller rolls, the adhesive layer continuously refreshes the contact surface. For example, with tear-off lint rollers, you can peel off the used layer to expose a new adhesive surface, avoiding the reduction in effectiveness due to saturation. Continuous adhesion is achieved through the rotating roller, making it suitable for cleaning large areas such as clothes and sofas. The layered structure of the adhesive layer, extending to the surface, allows users to peel off the soiled layer, keeping the adhesive clean and extending its lifespan. Some products use biodegradable materials or water-soluble adhesives, reducing environmental pollution. Lint rollers are widely used in pet-owning households to quickly remove pet hair and reduce allergens. Lint rollers are often used for clothing care, removing dust and lint from clothes to keep them tidy. Lint rollers are also widely used for household cleaning, cleaning fabric surfaces such as sofas, carpets, and curtains.

[0004] Existing lint rollers require manual force to install the roller by opening the lint roller bracket, inserting the pivot assembly (comprising the roller and rotating parts) into the bracket, and then releasing the bracket to complete the assembly. Removing the roller also requires force to open the bracket, at least disassembling the rotating connection on one side of the roller. During use, improper or uneven force often causes individual components to break off and fall out, affecting the user experience. Replacing the roller requires pulling the connecting frame with both hands, making the roller prone to falling, inconvenient, dirty, and risky. Furthermore, the mounting roller component of the lint roller bracket is usually a relatively thick plastic plate, which can be difficult to pull and deform when replacing the roller, hindering the replacement process. To address this issue, patent document CN218045042U discloses a lint roller with a housing that rotatably engages with the left end of the lint roller. The housing also includes a telescopic component that rotatably engages with the right end of the lint roller. When the telescopic component moves away from the right end of the lint roller, the lint roller detaches from the housing. The component for mounting the lint roller is designed as an assembled, flexible connecting frame. During use, it is not necessary to pry open the lint roller bracket; the flexible connecting frame can be easily pulled to deform it, allowing for lint roller replacement. However, replacing the lint roller requires pulling the connecting frame with both hands, making the lint roller prone to falling off, inconvenient to use, easily soiling the lint roller, and posing a risk of breakage. Furthermore, the use of a flexible connecting frame results in more than 15 components in this lint roller. This increased number of components leads to greater manufacturing and assembly difficulties. After a period of use, deformation or instability of any component will degrade the overall performance and shorten the product's lifespan. Additionally, the numerous and dispersed parts, along with their small size, make them difficult to locate if they fall, potentially rendering the entire device unusable. Moreover, the complex flexible structure makes assembly inconvenient and reduces production efficiency. It represents a complex system replacing a simple one, resulting in high production costs and hindering practical industrial applications.

[0005] Patent document CN108309202A discloses an easy-to-use household lint roller. The support assembly includes a core shaft, a support bone socket, and support bones. The core shaft is fixed to an opening formed at the upper end of the handle and extends along the central axis of the lint roller. The core shaft can extend and retract along the central axis of the lint roller. When the core shaft extends or retracts, the free ends of multiple support bones extend or retract from positioning holes, and are in an open or closed state relative to the support bone socket and the lint roller. The open state formed by the support assembly prevents the surface of the lint roller from adhering tightly to the surface of lint-covered fabrics. The adsorption assembly then adsorbs and adheres fine fibers, hair, debris, or dust attached to the surface of the item to the adhesive paper on the surface of the lint roller. However, due to the open state formed by the support assembly, the surface of the lint roller has difficulty contacting the fabric surface, making it difficult to fully remove debris, short fibers, and dust through physical adhesion, resulting in poor fabric cleaning. Furthermore, the lint roller's structure is overly complex, making assembly inconvenient, production efficiency low, and product manufacturing costs high, which is detrimental to practical industrial applications.

[0006] Patent document CN214342211U discloses a user-friendly lint roller, including a connecting structure. An adjusting device is installed inside the connecting structure, and the adjusting device includes an adjusting screw. Two rotating plates are symmetrically arranged at the left and right ends of the adjusting screw. Two fixing devices are symmetrically installed on the adjusting screw, and a lint roller is installed between the two fixing devices. Each fixing device includes a limiting plate, and a connecting plate is provided on the outer wall of the limiting plate. A square block is provided at one end of the connecting plate. A telescopic rod is provided at the rear end of the connecting structure, and a threaded post is provided at the rear end of the telescopic rod. This user-friendly lint roller belongs to the field of household products. By setting a movable fixing device, the lint roller can fix rollers of different lengths; by setting a telescopic rod, a threaded post, and a handle, the length of the lint roller can be easily adjusted, thus facilitating cleaning in narrow spaces. Based on the search of the aforementioned patents and in conjunction with existing lint rollers, it was found that although the aforementioned lint rollers can fix rollers of different lengths when in use, the adjustment screw needs to be turned repeatedly when disassembling and assembling the lint rollers, which is cumbersome, inconvenient, labor-intensive, and has low practicality.

[0007] Patent document CN220459316U discloses a lint roller device, including a mounting base, a lint roller, and mounting components for easy assembly and disassembly of the lint roller. By incorporating a cavity, a sliding plate, a rod, a through hole, a socket, a guide rod, a first spring, and control components, the rod can be inserted into the socket to fix the slider, which in turn fixes the second fixing plate and the second rotating shaft, thereby securing the lint roller and facilitating its use. The inclusion of a mounting base, lint roller, first fixing plate, first rotating shaft, sliding opening, slider, second fixing plate, second rotating shaft, first slot, second slot, fixing components, and a pop-out component facilitates quick disassembly and replacement of the lint roller and provides stable fixation. However, the complex structure and numerous components make assembly difficult, resulting in high manufacturing costs and less than ideal practicality.

[0008] Replacing the adhesive paper in existing lint rollers requires multiple steps, including disassembling the roller, aligning the adhesive paper, and reassembling. The assembly involves many parts, is time-consuming, and prone to errors. Some lint rollers also require tools for replacement, making the process cumbersome. This reduces users' willingness to replace the adhesive paper, hinders the circular economy, and leads to product idleness or decreased cleaning effectiveness.

[0009] Furthermore, while existing lint rollers are primarily made of plastic, resulting in lower costs, some low-priced and ultra-low-priced models use inferior materials, have poor workmanship, and are prone to breakage of handles and supports. Loose adhesive clips also affect the lifespan of the lint roller. Some lint rollers even suffer clip damage during refill replacement, rendering the product unusable. In addition, plastic lint rollers are difficult to degrade after use, causing significant environmental pollution. The willingness to recycle plastic lint rollers after they are discarded is low, potentially leading to further environmental problems. Utility Model Content

[0035] Compared with the prior art, this utility model has the following substantial features and advantages:

[0036] 1. While metal support structures offer good structural strength, they are difficult to deform elastically. This invention utilizes an elastic telescopic structure for assembling the lint roller, making it possible to manufacture support devices using metal or other rigid materials. It allows for quick and convenient installation of replaceable lint rollers into the support, as well as rapid disassembly and replacement. When the support is made of rigid materials like metal, its strength far exceeds that of plastics widely used in existing supports, effectively resisting external impacts and compression. Metal-supported lint rollers are less prone to deformation under frequent disassembly, stress, and large torques. Therefore, using rigid materials for components in the lint roller can prevent structural damage from collisions or compression, improving durability and extending service life. This invention, using an elastic telescopic structure for assembly, offers significant advantages in ease of use, cleaning efficiency, structural stability, and user experience. Furthermore, lint roller devices and their parts made of rigid materials like metal are more readily recyclable than those made of plastic, contributing to waste resource conservation and the realization of a circular economy.

[0037] 2. The lint roller of this utility model has a structured design with fewer components or parts. Some parts adopt an integrated modular design, which eliminates the assembly process of some parts of the traditional lint roller, reduces the assembly steps when changing the roller, makes it easy to assemble and disassemble, has high efficiency in changing the paper roll, and provides a good user experience.

[0038] 3. The lint roller assembled with an elastic telescopic structure of this utility model provides the possibility for manufacturing support devices made of metal and other rigid materials, enabling the lint roller surface to form richer surface materials, creating a texture different from plastic products, developing more styles and qualities of lint roller products, and meeting the diverse needs of users.

[0039] 4. The lint roller of this utility model has a more stable structure and a longer service life due to the use of a non-deformable lint roller bracket and a deformable and telescopic roller unit that can change length. Attached Figure Description

[0061] The preferred embodiments of this utility model are described in detail below:

[0062] Example 1:

[0063] In this embodiment, as Figure 1-3 As shown, a quick-release lint roller includes a handle 1, a lint roller bracket, and a lint roller assembly; the handle 1 is fixedly connected to the web plate 2.

[0064] The lint roller bracket includes a web plate 2, a left side plate 4, and a right side plate 3; the left side plate 4 and the right side plate 3 are respectively fixedly connected to the left and right ends of the web plate 2 to form an opening structure for accommodating the lint roller bracket 5; the opening structure and the handle 1 are respectively located on different sides of the front and back of the web plate 2.

[0065] The lint-removing roller device includes a roller unit and a drum 5;

[0066] The roller unit is a mandrel device with a variable axial length and an elastic telescopic structure; the mandrel device is movably connected to the left side plate 4 and the right side plate 3 at both ends to form a rotating mechanism; a roller 5 is sleeved on the outside of the mandrel device to form a roller support connection structure; the roller 5 is composed of an inner cylinder 13 and an adhesive layer 14, and the adhesive layer 14 is attached to the outer surface of the inner cylinder 13; the roller unit forms a detachable connection structure with the lint roller bracket and the roller 5 respectively.

[0067] This embodiment of a quick-release lint roller features a web plate 2, a left side plate 4, and a right side plate 3 that together form a clamping structure for mounting a paper tube 5. The roller unit is rotatably connected at both ends to the inner sides of the left side plate 4 and the right side plate 3. The roller unit is an elastic axial telescopic device, forming a detachable connection structure with the lint roller support and the paper tube 5. This quick-release lint roller, employing an elastic axial telescopic roller unit with a detachable connection structure to the lint roller support and the paper tube, represents a novel assembly and connection method for lint rollers. It offers a significant alternative and improvement over existing lint rollers, which are primarily made of plastic and require disassembly by prying open side plates. The axial telescopic installation structure of this embodiment facilitates the replacement of most existing lint roller components made of plastic with rigid materials such as metal, enabling product innovation, meeting more personalized needs, and diversifying the product offerings.

[0068] This embodiment, by employing an axial telescopic device, allows the use of rigid materials to replace plastic, thereby bringing new opportunities for industrial development and significantly improving the durability of lint rollers, enhancing their impact and deformation resistance. Metal materials are far stronger than plastics, effectively resisting external impacts and compression. Using metal materials in lint rollers can prevent structural damage caused by drops or compression, extending their service life. This embodiment, through structural improvements to existing technologies, provides a technological contribution to the upgrading of lint roller products.

[0069] This embodiment, by employing an axial telescopic device, makes it possible to replace plastics with metals and other rigid materials, achieving excellent high-temperature resistance. Metals have a much higher melting point than plastics, allowing them to withstand high-temperature environments without deformation. If the lint roller needs to be used with high-temperature cleaning tools such as chimney cleaners, the metal structure ensures safety and stability. The axial telescopic device optimizes the cleaning efficiency and structural stability of the lint roller, making the device's structural design more reliable. Its high strength also prevents the roller from deforming due to long-term use, ensuring uniform stickiness distribution and improving cleaning effectiveness.

[0070] Example 2

[0071] This embodiment is basically the same as Embodiment 1, except that:

[0072] In this embodiment, the length of the mandrel device in the rotating mechanism state is not greater than the natural length of the mandrel device.

[0073] In this embodiment, when the length of the mandrel device in the installed state is equal to its natural length, it indicates that the mandrel device has returned to its natural length state after installation, ensuring that the mandrel used when the roller rolls is at its natural length, and simplifying the mandrel assembly structure. In this embodiment, when the length of the mandrel device in the installed state is less than its natural length, the mandrel operates under axial pressure, maintaining the stability of the connection structure under elastic internal stress. This helps prevent the connection structure from disintegrating under external forces, making the working structure of the lint roller device more stable.

[0074] Example 3

[0075] This embodiment is basically the same as the previous embodiments, except that:

[0076] In this embodiment, as Figure 4-13 As shown, the elastic telescopic component in the mandrel device is an elastic telescopic rod 7.

[0077] The roller unit includes an elastic telescopic rod 7, a left annular end cap 8, and a right annular end cap 9. The left annular end cap 8 or the right annular end cap 9 is a flange-shaped structural component consisting of a bushing and a flange fixedly connected together. The outer diameter of the flange is larger than the inner diameter of the inner cylinder 13 of the roller 5, and the outer diameter of the flange is not larger than the outer diameter of the inner cylinder 13 of the roller 5. The left annular end cap 8 and the right annular end cap 9 serve as support components for the roller 5, and also as limiting baffle assemblies that constrain the axial movement of the two ends of the roller 5, so that the two ends of the roller 5 are respectively sleeved on the bushings of the left annular end cap 8 and the right annular end cap 9, and the bushings are sleeved on the elastic telescopic rod 7.

[0078] like Figure 4-5 As shown, the elastic telescopic component in the mandrel device is the elastic telescopic rod 7. The elastic telescopic rod 7 has a spring element inside that provides elastic force. Applying pressure F to one end of the elastic telescopic rod 7 causes it to shorten by a length ΔL, meaning the length difference before and after the telescopic deformation is ΔL. When replacing the roller 5, by shortening the length of the elastic telescopic rod 7, one end of the elastic telescopic rod 7 is connected, the other end is aligned with the connection position, and the elastic telescopic rod 7 is released, causing the other end to lock, thus completing the installation of the elastic telescopic rod 7. When disassembling the elastic telescopic rod 7, the same process is repeated: shortening the length of the elastic telescopic rod 7, first removing one end from the connection position, and then removing the shortened other end, thus completing the unloading of the shortened elastic telescopic rod 7. Figure 6 As shown, this is a movable connection structure for assembling an elastic telescopic rod and a lint roller bracket, which is easy to assemble.

[0079] like Figure 7-9As shown, the left annular end cap 8 and the right annular end cap 9 serve as the axial constraint components of the roller 5, the inner cylinder support components of the roller 5, and the intermediate connecting parts connecting the roller 5 and the elastic telescopic rod 7. The inner diameter of the bushing of the left annular end cap 8 and the right annular end cap 9 is D1, the outer diameter of the bushing is D2, the outer diameter of the flange is D3, and the height of the bushing excluding the flange is h. Figure 10 and Figure 13 As shown, when the left annular end cap 8 and the right annular end cap 9 are assembled with the roller 5, the outer diameter D3 of the flange is greater than the inner diameter of the inner cylinder 13 of the roller 5, and the outer diameter D3 of the flange is not greater than the outer diameter of the inner cylinder 13 of the roller 5. Figure 10 As can be seen from the assembly structure of the roller unit in this embodiment, Figure 13 As can be seen, the overall appearance and structure of the quick-release lint roller exposed at the partial edges of the left and right annular end caps in this embodiment are as follows.

[0080] like Figure 10-13 As shown, the left annular end cap 8 or the right annular end cap 9 is a flange-shaped structural component consisting of a bushing and a flange fixedly connected. The short cylindrical part on the inner side of the small outer diameter of the left annular end cap 8 or the right annular end cap 9, i.e. the sleeve, can be detachably inserted into both ends of the paper tube 5 to form an inner sleeve that supports the inner wall of the paper tube 5. The flange of the left annular end cap 8 or the right annular end cap 9 forms a limiting baffle structure that restricts the axial movement of both ends of the paper tube 5.

[0081] Preferably, the elastic telescopic rod 7 in this embodiment is a round rod, a prismatic rod, or other straight rod.

[0082] In this preferred embodiment, the left side plate 4 and the right side plate 3 are respectively vertically fixedly connected to the web plate 2, forming an integrated open frame structure for the lint roller support. This embodiment has a more reasonable structure, is easier to process and manufacture, and is easier to use and maintain.

[0083] This embodiment utilizes a flexible telescopic rod to assemble the lint roller, enabling the manufacture of devices using metal and other rigid materials. This offers significant advantages in durability, cleaning efficiency, structural stability, environmental friendliness, and user experience. The axial telescopic mounting structure facilitates the replacement of plastic materials with rigid materials, meeting diverse and personalized needs. While metal support structures offer high structural strength, they are difficult to deform elastically. This embodiment utilizes an elastic telescopic structure for assembling the lint roller, enabling the manufacture of support devices using metal or other rigid materials. It allows for quick and convenient installation of replaceable lint rollers into the support, as well as rapid disassembly and replacement. When the support components are made of rigid materials like metal, their strength far exceeds that of plastics widely used in existing supports, effectively resisting external impacts and compression. Metal-supported lint rollers are less prone to deformation under frequent assembly / disassembly, stress, and large torques. Therefore, using rigid materials for components in the lint roller can prevent structural damage from impacts or compression, improving durability and extending service life. This embodiment employs an elastic telescopic structure for assembly, offering significant advantages in ease of use, cleaning efficiency, structural stability, and user experience. Furthermore, lint roller devices and their parts made of rigid materials like metal are more readily recyclable than those made of plastic, facilitating waste resource recovery and the realization of a circular economy.

[0084] Example 4

[0085] This embodiment is basically the same as the previous embodiments, except that:

[0086] In this embodiment, as Figure 14-16 As shown, the left annular end cap 8 is fixedly connected to the body of the elastic telescopic rod 7, forming an elastic telescopic integrated assembly with a blocking structure. The right annular end cap 9 is detachably fitted onto the body of the elastic telescopic rod 7. In this embodiment, the left annular end cap 8 forms a handheld part for manual operation, which is beneficial for operating the telescopic rod's telescopic deformation and facilitates the insertion of the other end of the telescopic rod into the telescopic rod end mounting position, enabling quick assembly and disassembly of the lint remover. The right annular end cap 9 is detachably fitted onto the body of the elastic telescopic rod 7, enabling the necessary assembly operation steps for the roller unit. This embodiment of the novel lint remover features a structured design with fewer components or parts. Some parts adopt an integrated modular design, eliminating the assembly process of some parts in traditional lint removers, reducing the assembly steps when changing rollers, making it easy to assemble and disassemble, highly efficient in changing paper tubes, and providing a good user experience.

[0087] Alternatively, similar technical solutions can be adopted, whereby the right annular end cap 9 is fixedly connected to the body of the elastic telescopic rod 7, forming an elastic telescopic integrated assembly with a blocking structure. The left annular end cap 8 is detachably fitted onto the body of the elastic telescopic rod 7. In this embodiment, the right annular end cap 9 forms a handheld part for manual operation, which facilitates the operation of the telescopic rod's extension and contraction, and makes it easy to insert the other end of the telescopic rod into the telescopic rod end mounting position, enabling quick assembly and disassembly of the lint roller. The left annular end cap 8 is detachably fitted onto the body of the elastic telescopic rod 7, enabling the necessary assembly operations of the roller unit.

[0090] This embodiment is basically the same as the previous embodiments, except that:

[0091] In this embodiment, as Figure 6 , Figure 17-19 As shown, the two ends of the elastic telescopic rod 7 are respectively connected to the connecting parts inside the left side plate 4 and the right side plate 3 to form a rotating mechanism. The rotating mechanism adopts any of the following structures:

[0092] The first structure: Rotating shaft holes 6 are provided on the inner sides of the left side plate 4 and the right side plate 3. Small short shafts 10 are formed at both ends of the elastic telescopic rod 7. The small short shafts 10 and the rotating shaft holes 6 form a plug-in rotating structure, as shown below. Figure 6 As shown;

[0093] The second structure: The inner surfaces of the left side plate 4 and the right side plate 3 are provided with protruding short shafts 11, and the two ends of the elastic telescopic rod 7 form snap-fit ​​shaft holes 12. The protruding short shafts 11 and the snap-fit ​​shaft holes 12 form a plug-in rotation structure, such as... Figure 17 As shown;

[0094] The third structure: The inner side of the left side plate 4 is provided with a rotating shaft hole 6, the inner side of the right side plate 3 is provided with a protruding short shaft 11, the left end of the elastic telescopic rod 7 forms a small short shaft 10, and the right end of the elastic telescopic rod 7 forms a snap-fit ​​shaft hole 12. The small short shaft 10 and the rotating shaft hole 6 form a plug-in rotating structure, and the protruding short shaft 11 and the snap-fit ​​shaft hole 12 form another plug-in rotating structure. Figure 18 As shown;

[0095] The fourth structure: A protruding short shaft 11 is provided on the inner side of the left side plate 4; a rotating shaft hole 6 is provided on the inner side of the right side plate 3; a snap-fit ​​shaft hole 12 is formed at the left end of the elastic telescopic rod 7; and a small short shaft 10 is formed at the right end of the elastic telescopic rod 7.

Figure 19 As shown;

[0096] The rotating shaft hole 6 and the snap-fit ​​shaft hole 12 are countersunk holes or through holes, such as... Figure 6 , Figure 17-19 As shown.

[0097] This embodiment features a flexible telescopic rod forming a rotating connection structure, which facilitates the extension and contraction of the telescopic rod and allows for easy insertion of the other end of the telescopic rod into the installation position, enabling rapid assembly and disassembly of the lint roller. This embodiment, employing a flexible telescopic structure for assembly, makes it possible to manufacture the device body using metal or other rigid materials. When metal is used, its strength far exceeds that of plastic, effectively resisting external impacts and compression. For example, alloy lint rollers are less prone to deformation under frequent assembly / disassembly, stress, and large torques. Using metal or other rigid materials to make the lint roller avoids structural damage caused by impacts or compression, extends its service life, and allows for flexible and diverse structural designs.

[0098] Example 6

[0099] This embodiment is basically the same as the previous embodiments, except that:

[0100] In this embodiment, the inner sides of the left side plate 4 and the right side plate 3 are provided with protruding structures; or the outer sides of the flanges of the left annular end cap 8 and the right annular end cap 9 are provided with protruding structures.

[0101] In a further embodiment, the protruding structure is a rib or a dot structure.

[0102] In this embodiment, a raised structure is provided on the inner side of the left and right side plates or the outer side of the outer edge of the annular end cap, which helps to reduce the contact friction between the outer side of the left and right side plates and the outer side of the annular end cap, making it more convenient for the roller to rotate around the elastic telescopic rod as an axis.

[0103] In a further preferred embodiment, the raised structure is a rib or a dot structure. Using ribs and dots simplifies the structure. When the raised structure is a rib or dot structure in this embodiment, the raised structures on the inner surfaces of the left and right side plates or the outer surfaces of the annular end cap do not obstruct each other. The goal is to change surface contact to small-sized surface contact, line contact, or midpoint contact, reducing the contact area and thus lowering the contact friction on the outer surfaces of the left and right side plates and the annular end cap.

[0104] Example 7

[0105] This embodiment is basically the same as the previous embodiments, except that:

[0106] In this embodiment, as Figure 1-2 and Figure 6 As shown, the handle 1 is detachably connected to the middle or end of the top of the web plate.

[0107] This embodiment has a simple structure, is easy to manufacture, has a stable structure, and is easy to operate and use.

[0108] Example 8

[0109] This embodiment is basically the same as the previous embodiments, except that:

[0110] In this embodiment, the adhesive layer 14 of the roller 5 is a roll of lint-free paper wound around the inner cylinder 13. Using a paper cylinder wound with a tearable lint-free paper roll significantly improves cleaning efficiency and is convenient to use.

[0111] Example 9

[0112] This embodiment is basically the same as the previous embodiments, except that:

[0113] In this embodiment, as Figure 20 As shown, the elastic telescopic rod 7 in this embodiment adopts an elastic sheet assembly, or the elastic component in the elastic telescopic rod (7) is an elastic block or an elastic ball, which is also easy to deform under pressure F, so that the elastic telescopic rod 7 shortens its length ΔL, realizes deformation and expansion, and facilitates the assembly of the roller unit.

[0114] Example 10

[0115] This embodiment is basically the same as the previous embodiments, except that:

[0116] In this embodiment, as Figure 21As shown, the inner surface of the flange of the left annular end cap 8 or the right annular end cap 9 is provided with a raised blocking structure. The raised blocking structure can constrain or block the end of the elastic telescopic rod 7 or the shoulder structure near the end, so that the annular end cap with the raised blocking structure on the inner surface of the flange forms a handhold of the manual operation part, which is conducive to operating the telescopic rod's extension and contraction deformation, and makes it easy to install the other end of the telescopic rod into the telescopic rod end installation position, realizing the quick assembly and disassembly of the lint roller. It is easy to assemble and disassemble, has high paper tube replacement efficiency, and provides a good user experience.

[0117] In summary, this utility model, employing an elastically telescopic structure for assembly, makes it possible to manufacture the device body using metal and other rigid materials. When metal is used, its strength far exceeds that of plastic, effectively resisting external impacts and compression. For example, alloy lint rollers are less prone to deformation under frequent disassembly, stress, and large torques. Using metal or other rigid materials for the lint roller avoids structural damage caused by impacts or compression, extending its service life. This utility model, employing an elastically telescopic structure for assembly, makes it possible to manufacture the device body using metal and other rigid materials, offering significant advantages in durability, cleaning efficiency, structural stability, environmental friendliness, and user experience. This utility model has fewer components or parts, making it easy to assemble and disassemble, with high paper roll replacement efficiency and a good user experience. The use of a non-deformable lint roller support in this utility model makes the device structure more stable and extends its service life.
