DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0031] like Figure 1-Figure 6 As shown, a lint remover that is easy to replace includes at least a lint remover roller 1 and a handheld unit 2 connected to the lint remover roller 1, a locking assembly 3 is provided between the lint remover roller 1 and the handheld unit 2, and the locking assembly 3 includes a sliding channel 31 located on the lint remover roller 1, a locking member 32 that can move along the sliding channel 31, a reset member 33 that abuts against the locking member 32, and a positioning groove 34 formed on the handheld unit 2.

[0032] When the lint-removing roller 1 needs to be replaced, external force is applied to press the locking piece 32, so that the part of the locking piece 32 that falls into the positioning groove 34 is disengaged from the positioning groove 34, thereby unlocking the lint-removing roller 1 and the hand-held unit 2, and the lint-removing roller 1 can be disengaged from the hand-held unit 2 for replacement; when the new lint-removing roller 1 is placed at the corresponding position of the hand-held unit 2, or in other words, when the new lint-removing roller 1 is squeezed into part of the hand-held unit 2, under the action of the reset piece 33, part of the locking piece 32 can extend into the positioning groove 34, thereby entering the locked state of the lint-removing roller 1 and the hand-held unit 2, and the lint-removing roller 1 is fixedly assembled on the hand-held unit 2.

[0033] Specifically, Figure 5 , Figure 6 , Figure 8-Figure 12 As shown, the end of the hair-removing roller 1 has an end cap 11, and a portion of the end cap 11 extends axially to form a sliding channel 31, and a limiting groove body 311 is formed on the side wall of the sliding channel 31. The lock 32 is sleeved in the end cap 11, and correspondingly, the outer wall of the lock 32 forms a limiting protrusion 321, and the limiting protrusion 321 can fall into the limiting groove body 311 and form an anti-slip fit therewith. When the lock 32 moves in the sliding channel 31, the limiting protrusion 321 moves in the limiting groove body 311, and the limiting groove body 311 limits the sliding stroke of the lock 32.

[0034] In this embodiment, there are two limiting protrusions 321 , which are symmetrically distributed on both sides of the locking element 32 in the radial direction. Correspondingly, there are also two limiting grooves 311 .

[0035] In this embodiment, the end cover 11 and the lock 32 are arranged concentrically and coaxially, and the sliding channel 31 is a hollow part located inside the end cover 11. In order to ensure that the lock 32 translates in the sliding channel 31, a slide groove 351 and a protrusion 352 are arranged between the sliding channel 31 and the lock 32. The slide groove 351 and the protrusion 352 extend along the axial direction of the end cover 11, and the protrusion 352 falls into the slide groove 351. The two realize anti-rotation cooperation, so that the lock 32 will not deflect circumferentially relative to the end cover 11. Specifically, the protrusion 352 is arranged on the outer wall of the lock 32, and the slide groove 351 is arranged on the inner wall of the sliding channel 31. Of course, the positions of the protrusion 352 and the slide groove 351 can also be interchanged.

[0036] In order to facilitate the stable installation of the reset member 33, a mounting post 36 is provided in the sliding channel 31, and the reset member 33 is sleeved on the outside of the mounting post 36. The mounting post 36 is coaxially arranged with the lint-removing roller 1, that is, the mounting post 36 is coaxially arranged with the end cover 11 and the locking member 32. Specifically, the sliding channel 31 is formed by a cylindrical side wall, and its end face is closed, and the mounting post 36 is arranged on the inner surface of the end face. In this embodiment, the sliding channel 31 extends along the axis direction of the lint-removing roller 1 and toward the inner side of the lint-removing roller 1, and the mounting post 36 extends in a direction away from the lint-removing roller 1.

[0037] like Fig.10 As shown, the end cover 11 also has a clamping portion 12 which is coaxially arranged with the sliding channel 31 and is located at the radial outer periphery of the sliding channel 31. The clamping portion 12 can be fitted with the inner wall of the hair-sticking roller 1 by interference fit, and the outer wall of the clamping portion 12 has a ridge 121. A plurality of ridges 121 arranged at intervals along the circumference can ensure a stable fit between the clamping portion 12 and the inner wall of the hair-sticking roller 1. Of course, in order to prevent the end cover 11 from moving inward excessively, a retaining edge 112 can be formed on the outer ring of the end cover 11. The retaining edge 112 can abut against the end face of the hair-sticking roller 1 to prevent the end cover 11 from continuing to move inward. At the same time, the retaining edge 112 is connected with the ridge 121 in a cooperative manner, which also increases the structural firmness of the clamping portion 12.

[0038] In order to facilitate the installation of the lock member 32 in the end cover 11, Fig.12 As shown, the lock 32 forms a plurality of spaced spring structures 322 at one end of the sliding channel 31, and the limiting protrusion 321 is arranged at the end of the spring structure 322 facing the inner side of the end cover 11. Thus, the plurality of spring structures 322 are squeezed and installed into the end cover 11, and under the automatic reset action of the spring structure 322, the limiting protrusion 321 falls into the limiting groove 311, and the assembly is completed. After assembly, the structure is relatively stable.

[0039] In order to ensure a flat appearance and avoid mis-triggering, when part of the locking element 32 extends into the positioning groove 34 , the end surface of the locking element 32 is flush with the end surface of the handheld unit 2 .

[0040] The number of the locking components 3 can be one or two, that is, the locking components 3 can be arranged at one end of the lint-removing roller 1 alone, or can be symmetrically distributed at both ends of the lint-removing roller 1 .

[0041] like Figure 7 , Fig.13 As shown, the handheld unit 2 includes a handle 21 and a bracket 22 rotatably connected thereto, and an elastic positioning component 23 is provided between the handle 21 and the bracket 22. The elastic positioning component 23 is used to limit the two to be at a target angle for ease of use.

[0042] Specifically, the elastic positioning assembly 23 includes a conical groove 231 formed on the bracket 22, and a locking tongue 232 elastically connected to the handle 21. Fig.13Taking the direction shown as an example, the bracket 22 has an extension section 221, the center line of which is perpendicular to the center axis of the hair-removing roller 1, and the conical groove body 231 is located at the end surface of the extension section 221. The conical groove body 231 refers to the side wall of the groove body that is conical in shape with a larger upper part and a smaller lower part in the longitudinal section, and the top is open. The locking tongue 232 is coaxially arranged in the handle 21, and a spring 234 is installed between it and the handle 21. The end surface of the locking tongue 232 facing the bracket 22 has a frustum surface 233, and the frustum surface 233 refers to the longitudinal section of which is conical in shape with a larger upper part and a smaller lower part, and the frustum surface 233 can just fall into the conical groove body 231, and the conical surfaces of the two are offset.

[0043] like Figure 7 As shown, the extension section 221 is provided with an end outer wall of a conical groove body 231 having an avoidance surface 222, and the end of the handle 21 is clamped on both sides of the extension section 221, and the inner wall close to the end of the extension section 221 forms an action surface 211, and the action surface 211 is a conical surface formed by cutting the inner wall of the end of the handle 21, which is small at the top and large at the bottom. Therefore, when the handle 21 rotates relative to the extension section 221, the action surface 211 moves against the avoidance surface 222, which can drive the cone surface 233 to separate from the conical groove body 231.

[0044] When in use, the handle 21 is rotated to be coaxial or nearly coaxial with the extension section 221, the conical surface 233 falls into the conical groove body 231, the locking tongue 232 is locked with the extension section 221, and the handle 21 is kept in a use state perpendicular to the lint-removing roller 1; an external force is applied to rotate the handle 21, the action surface 211 moves against the avoidance surface 222, and the conical surface 233 can be separated from the conical groove body 231, releasing the lock tongue 232 and the extension section 221, so that the handle 21 enters a folded storage state, which is convenient and labor-saving to operate.

[0045] In order to prevent the lint roller 1 from being contaminated, or to facilitate the storage of the lint remover, the outer cover of the lint roller 1 is provided with a cover body 4, the top of the cover body 4 forms a notch for the extension section 221 to extend into, and the outer wall of the cover body 4 has bristles 41, specifically, as Figure 3 As shown, the bristles 41 are located obliquely below the cover body 4. The bristles 41 can pre-treat the object to be processed before using the lint roller 1 to remove dust, hair, etc., which has a better processing effect on the object and prolongs the service life of the lint roller 1.

[0046] The above specific implementation modes are used to explain the present invention rather than to limit the present invention. Any modification and change made to the present invention within the spirit of the present invention and the protection scope of the claims shall fall within the protection scope of the present invention.
