Description
Technical Field
[0001] This utility model relates to the field of household products technology, specifically to a portable lint roller. Background Technology
[0002] In daily life, stick-type lint rollers are popular for removing hair and dust from clothing and fabrics due to their compact size and easy operation. They are also easy to carry and widely welcomed by users. Existing stick-type lint rollers typically use a structure where a fixed-length handle is rigidly connected to the lint-removing component. While this meets basic cleaning needs, it has significant shortcomings in terms of storage portability and operating costs.
[0003] Existing products have fixed handle lengths, and even small straight-bar lint rollers still require linear space when placed in handbags, pockets, or suitcases, making them difficult to fit into compact spaces such as small cosmetic bags or commuter bags.
[0004] Traditional stick-type lint rollers often use disposable lint rollers or non-removable lint heads. When the lint-removing surface becomes dirty or the stickiness is exhausted, users need to discard the entire unit or replace it with an expensive pre-assembled component. Some designs with replaceable lint heads rely on complex connection structures such as screws and clips, requiring tools or multiple alignments during replacement, which is time-consuming and laborious, and parts such as small clips are easily lost. In addition, the connection between the lint-removing component and the handle is mostly fixed, making it impossible to clean or replace the component independently, resulting in high per-use costs.
[0005] Therefore, overcoming the aforementioned shortcomings and providing a lint roller that is smaller, more portable, and easier to replace the lint-removing components has become an important issue that urgently needs to be addressed by those skilled in the art. Utility Model Content
[0006] This invention overcomes the shortcomings of the above-mentioned technology and provides a portable lint roller.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A portable lint roller includes a retractable handle assembly and a lint-removing component detachably connected to the handle assembly. The handle assembly is retractably inserted into the inner ring of the lint-removing component. The lint-removing component is rotatably connected to the handle assembly. A detachable bottom cover is connected to the lower end of the handle assembly. The bottom cover limits the lint-removing component to the handle assembly to prevent it from detaching from the handle assembly. The lint-removing component can be separated from the handle assembly after the bottom cover is removed.
[0009] Furthermore, the handle assembly includes a grip and a lint roller that is retractably connected to the grip. The lint roller has an internal hollow structure, and the grip is inserted into the lint roller. A limiting structure is provided between the grip and the lint roller to prevent the grip from detaching from the lint roller. A guide structure is also provided between the grip and the lint roller.
[0010] Furthermore, the limiting structure includes a first outer ring with a circumferential protrusion at the bottom of the grip and a first inner ring at the top of the inner ring of the lint roller, wherein the diameter of the first outer ring is larger than the diameter of the first inner ring.
[0011] Furthermore, the guide structure includes a guide rail recessed on the inner wall of the lint roller and a groove formed on the outer wall of the handle, the groove being slidably connected to the guide rail, and the guide rail extending longitudinally along the inner wall of the lint roller.
[0012] Furthermore, the bottom cover is detachably connected to the lint roller. The bottom cover includes a connecting part and a knob part. The connecting part includes an inner cylinder with a diameter smaller than the inner ring diameter of the lint roller and a protruding strip on the outer wall of the inner cylinder. The protruding strip is provided with a protrusion. The bottom of the lint roller is provided with a locking groove for the protrusion to slide and be inserted into a limiting position.
[0013] Furthermore, the lint-removing assembly includes a soft rubber tube and soft rubber covering the outer ring of the soft rubber tube, the soft rubber tube being fitted onto the outer ring of the handle assembly.
[0014] Furthermore, the portable lint roller also includes an outer cover for enclosing the lint-collecting components, the outer cover having an internally hollow structure.
[0015] Furthermore, the upper end of the lint roller has a second outer ring protruding from its outer periphery, and the outer periphery of the second outer ring has a convex plate that can be elastically deformed. The inner ring of the outer cover has a second inner ring. The lint roller assembly is inserted into the outer cover. The convex plate at the upper end of the lint roller is finally inserted and confined to the lower end of the second inner ring as the handle assembly is pressed down.
[0016] Furthermore, the inner wall surface of the outer cover is provided with a longitudinally extending protruding ridge, and the bottom of the protruding ridge is bent to form a first limiting part.
[0017] Furthermore, the bottom of the outer cover is provided with a second limiting part and a drain hole, and the upper end of the handle is provided with a hanging hole.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] This design utilizes a nested design between the retractable handle and the lint roller assembly, significantly reducing the lint roller's size when stored. This makes it easy to carry or hang for use when out and about, reducing packaging and transportation costs. The removable bottom cover allows for quick separation of the lint roller assembly and handle assembly, facilitating easy assembly and disassembly. Users can clean or replace the lint roller assembly separately, extending the overall lifespan of the lint roller and reducing the frequency of replacement. Simultaneously, the bottom cover's locking mechanism, combined with the rotating connection between the handle and lint roller assembly, ensures a stable connection during use, preventing accidental detachment during cleaning.

[0027] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art:
[0028] like Figures 1 to 7As shown, this invention provides a portable lint roller, including a retractable handle assembly 1 and a lint-removing assembly 2 connected to the handle assembly 1. The handle assembly 1 is retractably inserted into the inner ring of the lint-removing assembly 2. By providing a retractable handle assembly 1, the user can retract the handle assembly 1 when not using the lint roller, reducing the overall length of the lint roller; when the user needs to use it, the handle assembly 1 can be pulled out to a suitable length for convenient operation. This design greatly reduces the overall space occupied by the lint roller, making it convenient for users to store and carry the lint roller, and it can be easily placed in a small bag for convenient use when going out. At the same time, it facilitates the packaging and transportation for manufacturers, reducing their packaging and transportation costs. The lint roller assembly 2 is rotatably connected to the handle assembly 1, allowing the angle of the lint roller assembly 1 to be flexibly adjusted. When the user uses it, the friction between the lint roller assembly 2 and the object causes the lint roller assembly 2 to rotate relative to the handle assembly 1. This allows the lint roller assembly 1 to adhere to different cleaning surfaces, such as vertical clothing, tilted sofas, and curved chairs. Users do not need to frequently adjust their grip on the handle; they can hold the handle with one hand and rotate the lint roller assembly to cover complex surfaces, improving cleaning efficiency and operational comfort. A detachable bottom cover 3 is connected to the lower end of the handle assembly 1. The bottom cover 3 limits the connection of the lint roller assembly 2 to the handle assembly 1 to prevent it from detaching. After removing the bottom cover 3, the lint roller assembly 2 can be separated from the handle assembly 1. A detachable bottom cover 3 is connected to the lower end of the handle assembly 1. When the bottom cover 3 is installed, it secures the lint roller assembly 2 and the handle assembly 1, preventing accidental separation. After removing the bottom cover 3 from the handle assembly 1, the lint roller assembly 2 can be easily removed without tools, as it is detachably connected to the handle assembly 1. When the adhesive properties of the lint roller assembly 2 decrease or it becomes damaged after a period of use, the user can replace it themselves, saving the cost of purchasing a new lint roller. In this case, the lint roller assembly 2 is fitted over the handle assembly 1.
[0029] Reference Figures 1-3 , Figure 6 , Figure 7As shown, the handle assembly 1 includes a grip rod 11 and a lint roller 12 retractably connected to the grip rod 11. The lint roller 12 has a hollow internal structure, and the grip rod 11 is inserted into the lint roller 12. The grip rod 11, inserted into the lint roller 12, forms a sleeve-like telescopic structure. When retracted, most of the grip rod 11 is retracted into the lint roller 12, significantly shortening the overall length. The grip rod 11 provides a gripping fulcrum, and the lint roller 12 serves as the carrier of the lint roller assembly 2. The two work together to adjust the volume, and the hollow structure of the lint roller 12 provides space for the extension and retraction of the grip rod 11. A limiting structure is provided between the grip rod 11 and the lint roller 12 to prevent the grip rod 11 from detaching from the lint roller 12. By setting the limiting structure, it is possible to effectively prevent the grip rod 11 from completely detaching from the lint roller 12 when pulled out, thus affecting its use. A guide structure is also provided between the grip rod 11 and the lint roller 12. The guide structure is used to stably extend and retract the grip 11 and the lint roller 12, guide their extension and retraction movements, and reduce frictional resistance.
[0030] Continue to refer to Figures 1-3 , Figure 6 , Figure 7 As shown, specifically, the limiting structure includes a first outer ring 111 circumferentially protruding from the bottom of the grip 11 and a first inner ring 121 disposed at the top of the inner ring of the lint roller 12. The diameter of the first outer ring 111 is larger than the diameter of the first inner ring 121. In a specific implementation, the first outer ring 111 is an annular boss disposed at the end of the grip 11, surrounding the bottom of the grip 11. For ease of manufacturing, the first outer ring 111 is integrally formed with the main body of the grip 11. The first inner ring 121 is an annular limiting ring integrally formed at the top of the inner ring of the lint roller 12, and its inner diameter is slightly larger than the diameter of the first outer ring 111. This invention utilizes the diameter difference of the annular structure to form a limiting fit. When the grip 11 is stretched to its limit, the limiting fit between the first outer ring 111 and the first inner ring 121 can effectively prevent the grip 11 from coming off, avoiding accidental separation of the grip 11 from the lint roller 12 during cleaning. It should be noted that the specific structure of the first outer ring 111 and the first inner ring 121 can also be a discontinuous protrusion of annular sections, or a fan shape, as long as the corresponding limiting fit can be achieved. In this case, in order to ensure the stability of the connection between the grip 11 and the lint roller 12 when the grip 11 is pulled to the limit, as well as the stability during use, the first outer ring 111 and the first inner ring 121 are preferably set as annular.
[0031] Continue to refer to Figures 1-3 , Figure 6 , Figure 7As shown, specifically, the guide structure includes a guide rail 122 recessed into the inner wall of the lint roller 12 and a groove 112 formed on the outer wall of the grip 11. The groove 112 is slidably connected to the guide rail 122, which extends longitudinally along the inner wall of the lint roller 12. The interlocking of the guide rail 122 and the groove 112 creates a mechanical limit, preventing significant wobbling when the grip 11 extends or retracts relative to the lint roller 12, maintaining a straight line even with rapid single-handed extension. The guide structure limits the movement trajectory of the grip 11, preventing abnormal stress on the limiting structure due to misalignment and extending its overall service life. The smooth groove and rail reduce friction, providing a uniform feel during extension and retraction without any sticking or stiffness, making it particularly suitable for high-frequency use. Simultaneously, the interlocking of the guide rail 122 and the groove 112 achieves circumferential limiting of the grip 11 and the lint roller 12, allowing them to rotate coaxially. In specific implementation, to further improve the stability and smoothness of the extension and retraction of the grip 11 and the lint roller 12, in this case, preferably, two guide rails 122 are symmetrically arranged, and two grooves 112 are correspondingly symmetrically arranged. It should be noted that the guide rails 122 can also be arranged on the outer wall of the grip 11, in which case the grooves 112 can be formed on the inner wall of the lint roller 12, which can also achieve the same effect.
[0032] Furthermore, such as Figures 1-4 , Figure 6 , Figure 7 As shown, the bottom cover 3 is detachably connected to the lint roller 12. The bottom cover 3 includes a connecting part 31 and a knob part 32. The connecting part 31 facilitates connection with the lint roller 12, and the knob part 32 facilitates user removal of the bottom cover 3. The connecting part 31 includes an inner cylinder 311 with a diameter smaller than the inner diameter of the lint roller 12 and a protruding strip 312 on the outer wall of the inner cylinder 311. The inner cylinder 311 can act as a guide when the bottom cover 3 is inserted into the lint roller 12, ensuring that the bottom cover 3 and the lint roller 12 are coaxially aligned. The protruding strip 312 is provided with a protrusion 313, and the bottom of the lint roller 12 has a locking groove 123 for the protrusion 313 to slide and be inserted and limited. In a specific implementation, the locking groove is in the shape of a "7". The protrusion 312 provides a sliding track, and the protrusion 313 serves as a locking fulcrum. When the bottom cover 3 is rotated, the protrusion 313 slides along the vertical section of the locking groove 123 into the horizontal section, achieving a limit lock and ensuring the stability of the connection between the bottom cover 3 and the lint roller 12. This connection structure between the bottom cover 3 and the lint roller 12 requires no other parts and requires no tools for assembly or disassembly, making it convenient. To further enhance the stability of the connection between the bottom cover 3 and the lint roller 12, in this invention, preferably, two sets of protrusions 312, protrusions 313, and locking grooves are provided.
[0033] like Figure 1 , Figure 6 , Figure 7As shown, the lint-removing assembly 2 includes a soft rubber tube 21 and a soft rubber 22 covering the outer ring of the soft rubber tube 21. The soft rubber tube 21 is fitted onto the outer ring of the handle assembly 1 and can rotate relative to the handle assembly 1. In specific implementation, the soft rubber tube 21 is made of a rigid material and is used to hold the soft rubber 22. The soft rubber 22 uses its own adhesiveness and surface microstructure to adsorb hair, dust, and other impurities from clothing and furniture surfaces. The soft rubber 22 is washable; hair and dust on its surface can be directly washed away with water without the need for tools. After washing and drying, it can be reused, with almost zero maintenance costs and is reusable. When the soft rubber 22 wears down or its adhesiveness decreases, the user can replace the entire lint-removing assembly 2 by removing the bottom cover 3. It should be noted that the soft rubber 22 mentioned in this case is made of TPE or TPR material.
[0034] Furthermore, such as Figure 1 , Figures 5-7 As shown, the portable lint roller of this case also includes an outer cover 4 for enclosing the lint-collecting component 2, and the outer cover 4 has an internal hollow structure. Through the enclosing design of the outer cover 4, the problems of easy contamination and damage of the soft rubber 22 in traditional portable lint rollers are solved. Users do not need an additional protective cover and can easily carry it by simply putting it in their clothing pocket or bag.
[0035] Furthermore, such as Figure 1 , Figure 3 , Figures 5-7 As shown, a second outer ring 124 protrudes from the top outer periphery of the lint roller 12. A deformable protrusion 125 is provided on the outer periphery of the second outer ring 124. A second inner ring 41 is provided on the inner ring of the outer cover 4. The lint-removing component 2 is inserted into the outer cover 4. The protrusion 125 at the upper end of the lint roller 12 is finally inserted and confined to the lower end of the second inner ring 41 as the handle assembly 1 is pressed down. The protrusion 125 acts as a limiting element. By setting the cooperation between the protrusion 125 and the outer cover 4, the handle assembly 1 is prevented from shaking continuously in the outer cover 4. The protrusion 125 can be fastened to the second inner ring 41 of the inner ring of the outer cover 4, preventing the handle assembly 1 and the lint-removing component 2 from falling out of the outer cover 4. This further makes the portable lint remover of this invention more completely stored, smaller in overall size, more convenient to carry, and reduces packaging and transportation costs. By setting the second outer ring 124, the lint-removing component 2 is made to make flat contact with the tabletop, achieving better cleaning effect. This design, which uses the elastic protrusion 125 and the second outer ring 124 for limiting and engaging, solves the problems of the outer cover 4 being prone to shaking during storage and easy to detach during carrying. Together with the retractable handle assembly 1, the lint roller assembly 2, and the detachable bottom cover 3, it forms a complete portable protection system. In specific implementation, to ensure the stability of the outer cover 4 and the lint roller 12 when fastened together, at least two protrusions 125 are provided, and in this case, three are preferably provided.
[0036] like Figures 5-7As shown, further, longitudinally extending protruding ribs 42 are provided on the inner wall surface of the outer cover 4. The protruding ribs 42 contact the outer wall of the lint-adhesive assembly 2, restricting the radial movement of the lint-adhesive assembly 2, ensuring a straight insertion path, avoiding jamming caused by skewness, and further ensuring the stability of the installation of the outer cover 4 with the handle assembly 1 and the lint-adhesive assembly 2. The guide groove formed by multiple protruding ribs 42 reduces the contact area between the inner wall of the outer cover 4 and the lint-adhesive assembly 2, preventing the outer cover 4 from damaging the soft rubber 22. The bottom of the protruding ribs 42 is bent to form a first limiting part 421. When the handle assembly 1 and the lint-adhesive assembly 2 are inserted into the outer cover 4, they stop when the bottom touches the first limiting part 421, avoiding over-insertion that could cause the soft rubber 22 to squeeze and deform the bottom of the outer cover, or damage to the bottom of other components. The physical blockage of the first limiting part 421 provides a clear insertion endpoint, allowing the user to perceive the correct position without visual inspection, making installation precise and convenient. The protruding ribs 42 and the first limiting part 421 provided in this invention effectively solve the problems of easy misalignment and wasted space during the installation of the outer cover 4 through detailed structural optimization.
[0037] Furthermore, the bottom of the outer cover 4 is also provided with a second limiting part 43 and a drain hole 44, and the upper end of the handle 11 is provided with a hanging hole 113. The second limiting part 43 is used to prevent the bottom cover from being excessively inserted into the outer cover 4, facilitating quick and accurate positioning and further improving the convenience and stability of installation. Its function and effect can be referred to the corresponding description of the first limiting part 421 above. The drain hole 44 is used to drain water from the lint roller assembly 2 after cleaning, keeping the lint roller assembly 2 dry and preventing damage to the lint roller due to prolonged immersion in water. The hanging hole 113 facilitates the user's grip when using the telescopic handle assembly 1. The size and shape of the hanging hole 113 can be designed according to actual needs, usually circular or elliptical. At the same time, the hanging hole 113 allows the user to hang the lint roller on hooks, nails, or other objects on the wall, facilitating storage and saving space. After the user has finished cleaning the lint roller assembly 2, the lint roller can be hung through the hanging hole 113, and the water will leak out from the drain hole 44 at the bottom of the outer cover 4.
[0038] As stated above, this case protects a portable lint roller, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
