Description

Technical Field

[0001] This utility model relates to a hair remover, and more particularly to a handheld hair remover with an easy-to-replace lint roller. Background Technology

[0002] Handheld hair removers are used to remove human or pet hair that has fallen onto sofas, beds, or clothes.

[0003] The handheld hair remover includes a stand with a handle and a lint roller; the user holds the remover and the lint roller can be rotated and moved across the surface of the object, where hair or debris can be adhered. Since the lint roller is a consumable item and needs to be replaced after use, the lint roller is detachably mounted on the stand.

[0004] The following are descriptions of two different structural forms of roller lint removers:

[0005] The lint roller applicator, with announcement number CN214458906U, includes a lint roller, a housing, and a handle. The lint roller is rotatably mounted within the housing. A first handle connection port is located at one end of the housing, and a handle connector is located in the middle of the housing. A second handle connection port is located on the handle connector. The handle can be connected to both the first and second handle connection ports. This invention offers two usage methods, facilitates handle installation and removal, is stable and reliable, and improves the lint-removing effect and efficiency of the device, making it worthy of promotion.

[0006] A portable, foldable lint roller with announcement number CN222516807U features a foldable storage structure. The connection between the connecting plate and the side plates is a hinged, flip-up design. During assembly, the two side plates are supported by the lint rollers to maintain good stability. When the lint rollers are removed, the two side plates can be flipped and folded, and the folding stability is maintained by the engagement structure of the protrusions and springs. At the same time, since the handle and the connecting plate are assembled by inserting into the docking frame to form a locking block and slot, the handle can be removed, thereby improving the storage space occupied by the lint roller.

[0007] The existing lint roller structure requires both hands to operate the two interfaces of the mounting bracket to extend or deform elastically when changing the lint roller, so that the lint roller can be removed from the mounting bracket. Similarly, the same reverse operation is required to install it. This replacement operation is quite cumbersome. Utility Model Content

[0051] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0052] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0053] like Figures 1 to 4As shown, a handheld hair remover 100 with an easy-to-replace lint roller mainly includes a mounting frame 10 and a lint roller 20. The mounting frame 10, as the core support structure of the entire remover, consists of a handle 13 for the user to hold, a crossbeam 14 providing structural support, and a first forearm 11 and a second forearm 12 for mounting and fixing the lint roller 20.

[0054] The handle 13 is located in the middle of the rear side of the crossbeam 14. Its surface is treated with an anti-slip pattern, and its shape and size are ergonomic, providing users with a comfortable grip and ensuring that users can hold the cleaner firmly during use, easily control its direction and movement, and it will not slip even after long-term use or when hands are wet.

[0055] The crossbeam 14 is the main supporting component of the fixing frame 10, preferably made of high-strength material, and connects the first forearm 11 and the second forearm 12, providing sufficient structural strength and stability for the entire fixing frame 10. The first forearm 11 is fixedly connected to the first end a1 of the crossbeam 14, and has a first interface d1 on its inner side; the second forearm 12 is telescopically connected to the second end a2 of the crossbeam 14 through an elastic element s (preferably a spring), and has a second interface d2 on its inner side.

[0056] The aforementioned technical means enables the two ends of the lint roller 20 to be rotatably connected to the first interface d1 and the second interface d2 respectively, achieving stable installation and flexible rotation, while also facilitating user replacement of the lint roller 20, greatly improving ease of use.

[0057] In actual use, such as Figure 2 and Figure 3 As shown, and Figure 6 and Figure 7 , Figure 11 and Figure 12 As shown, through the action of the elastic element s, the user only needs to pull the second forearm 12 in the opposite direction to overcome the force of the elastic element s. The second interface d2 will move away from the first interface d1, and the second end c2 of the lint roller 20 will disengage from the second interface d2, thus easily removing the lint roller 20 from the fixing frame 10. During installation, the operation is reversed.

[0058] The mounting bracket 10 not only provides stable support for the handheld hair remover 100, but also, through the rational layout and functional design of the handle 13, crossbeam 14, first forearm 11, and second forearm 12, enables the quick installation and convenient replacement of the lint roller 20. This structure not only improves the product's practicality and user experience, but also provides greater convenience and flexibility for users when frequently replacing lint rollers to clean human or pet hair from sofas, beds, or clothing, allowing it to easily handle various cleaning scenarios.

[0059] Specifically, such as Figure 5 , Figures 8 to 10 As shown, the first forearm 11 is fixed to the first end a1 connected to the crossbeam 14, and the second forearm 12 is telescopically connected to the second end a2 of the crossbeam 14; an elastic element s is disposed between the crossbeam 14 and the second forearm 12; the inner side of the first forearm 11 is provided with a first interface d1, and the inner side of the second forearm 12 is provided with a second interface d2; the two interfaces adopt a protruding element t structure, which can accurately extend into the hole of the first end c1 of the cylindrical support body 21 of the lint roller 20, thereby realizing the stable installation and flexible rotation of the lint roller 20.

[0060] The aforementioned technical means not only ensures the stability of the lint roller 20 during use, but also ensures its firm connection to the fixing frame 10, preventing it from loosening or falling off during the cleaning process.

[0061] Furthermore, a telescopic part 121 is provided at the rear end of the second forearm 12, which is telescopically connected to the connecting hole w at the second end a2 of the crossbeam 14 via an elastic element s. This telescopic connection method is one of the core innovations of this utility model, which greatly facilitates the quick replacement of the lint roller 20.

[0062] More specifically, an L-shaped positioning block 40 is installed inside the connecting hole w. The positioning block 40 includes a first vertical limiting wall g1 and a positioning wall 41.

[0063] The outer end of the positioning wall 41 is provided with a buckle v1, which cooperates with the buckle hole v2 on the bottom wall of the crossbeam 14 to achieve stable positioning of the positioning block 40 and the second forearm 12.

[0064] In addition, such as Figure 10 As shown, the inner end of the telescopic part 121 is provided with a second vertical limiting wall g2, and the inner side is provided with a first guide post h extending laterally. Preferably, a second guide post m is provided on the first vertical limiting wall g1 of the positioning block 40; the two ends of the spring s are respectively sleeved on the first guide post h and the second guide post m. Since the two ends of the spring s are respectively sleeved on the first guide post h and the second guide post m, these two guide posts provide stable support and a clear direction of movement for the spring. During the relative movement between the telescopic part 121 and the positioning block 40, the spring s can extend and retract uniformly along the direction of the guide post, preventing the spring from tilting and deforming. The spring can always maintain a good elastic state, and the magnitude and direction of the elastic force are more stable and reliable.

[0065] Furthermore, regarding the specific installation position of the spring, one end of the spring abuts against the first vertical limiting wall g1, and the other end abuts against the second vertical limiting wall g2, providing elastic support. This technical means not only ensures the stability and reliability of the elastic element s, but also further optimizes the telescopic function of the second forearm 12, making the replacement operation smoother, ensuring the stability of the second forearm 12 during use, and preventing the lint roller 20 from loosening due to accidental pulling.

[0066] In actual use, the inner side of the second forearm 12 is provided with a second interface d2. Similar to the first interface d1, the second interface d2 also adopts a protruding T structure for connecting with the second end c2 of the lint roller 20. When the lint roller 20 needs to be replaced, the user only needs to pull the second forearm 12 in the opposite direction to overcome the force of the elastic element S. The second interface d2 will then move away from the first interface d1, allowing the second end c2 of the lint roller 20 to easily detach from the second interface d2. This technique makes the replacement of the lint roller 20 simple and quick, eliminating the need for the user to operate multiple interfaces with both hands, thus greatly improving replacement efficiency.

[0067] Regarding the lint roller 20, it should be noted that it includes a cylindrical support body 21, with its first end c1 and second end c2 rotatably connected between the first interface d1 and the second interface d2, respectively. This technology allows the lint roller 20 to rotate flexibly on the mounting frame 10, thereby effectively adhering to hair and debris during cleaning. The outer periphery of the cylindrical support body 21 is provided with at least one lint-adhesive layer 22, which is a peelable paper with an adhesive surface. This technology not only effectively adheres to hair and debris but also supports multi-layer installation, extending the service life of the lint roller 20. When the outermost lint-adhesive layer 22 loses its stickiness, the user can peel off one layer and continue using the next, thus reducing the frequency of replacement.

[0068] Preferably, the hair remover 100 of this technical solution also includes a cover 200. When not in use, the cover 200 can be placed over the outside of the lint roller 20 to prevent the lint roller 20 from accidentally sticking with hair when it is not needed.

[0069] When replacing the lint roller, first remove the old lint roller 20. The user holds the handle 13, ensuring the cleaner is stable in their hand. Then, with the other hand, pull the second forearm 12, overcoming the force of the elastic element s, to move the second interface d2 away from the first interface d1. As the second interface d2 moves, the second end c2 of the lint roller 20 will gradually detach from the second interface d2, and finally, the lint roller 20 can be easily removed from the holder 10.

[0070] Next, align the first end c1 of the new lint roller 20 with the first interface d1 and insert it, ensuring a stable connection. Then, align the second end c2 of the lint roller 20 with the second interface d2 and slowly release the second forearm 12. Under the action of the elastic element s, the second forearm 12 will automatically move towards the first forearm 11, so that the second interface d2 is tightly connected with the second end c2 of the lint roller 20, and the installation is finally completed.

[0071] In summary, this invention achieves a quick replacement function for the lint roller 20 by using a retractable second forearm 12 and an elastic element s. Users can easily disassemble the lint roller 20 by simply pulling the second forearm 12 in the opposite direction to overcome the force of the elastic element s, eliminating the need for two-handed operation of multiple interfaces. This greatly simplifies the replacement process, improves the user experience, and significantly saves time and effort, especially in scenarios where lint roller replacements are frequent.
