Description

Technical Field

[0001] This utility model relates to a lint roller with a replaceable lint roller, and belongs to the field of lint rollers. Background Technology

[0002] Lint rollers are tools used to remove dust and hair from clothes, sheets, or other items. They are mainly divided into two types: tearable lint rollers and washable lint rollers. Currently, the lint roller mounting part is usually a relatively thick plastic plate, which is difficult to pull and deform when replacing the roller, making replacement inconvenient. Chinese utility model patent CN202322635126.3 discloses a quick-release lint roller, including a housing and a lint roller that rotates relative to the housing. The housing has a sleeve that rotates relative to the left end of the lint roller. The housing also has a telescopic component that rotates relative to 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. This utility model allows for quick replacement of the lint roller by pressing, but it requires a full press. If the user's strength is insufficient, the lint roller cannot be disassembled, and the feedback from a fully pressed button is poor. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a lint roller that can replace the lint roller.

[0004] A lint roller replaceable includes a housing for mounting the lint roller. One end of the housing has a connecting shaft that rotatably engages with the lint roller, and the other end has a push block. The push block is linked to a telescopic part that rotatably engages with the lint roller. The push block, through a pushing motion, disengages the telescopic part from the lint roller, allowing the lint roller to separate from the housing. Traditional lint roller replacements often rely on prying open a large, thick plastic sheet or forcefully pressing the clips, which is laborious and provides a poor feel. This invention features a dedicated push block at the other end of the housing, linked to the telescopic part. A single linear push disengages the telescopic part from the lint roller, allowing the roller to quickly separate from the housing. The operation requires minimal effort, making it easy for the elderly and children to replace the lint roller; the force and displacement are precisely controlled, allowing the user to clearly perceive the "positioning."

[0005] Preferably, the housing has a mounting base, and a pushing cavity is formed between the mounting base and the housing. The pushing block includes a pushing part located outside the mounting base and a driving part extending into the pushing cavity. The driving part has an inclined slide rail. The telescopic part includes a locking block for engaging with the lint roller and a slider slidably connected to the slide rail. The pushing block, through a pushing action applied to the pushing part, causes the slider on the telescopic part to slide along the slide rail, thereby causing the locking part to retract into the pushing cavity, separating the lint roller from the housing. The pushing cavity between the mounting base and the housing defines the movement space of the pushing block, allowing the pushing force to be concentrated and transmitted to the driving part. The stroke length and force are easy to design and adjust, ensuring a consistent feel for each replacement operation and preventing incomplete locking due to overshoot or undershoot. The inclined slide rail on the driving part decomposes the linear thrust of the pushing part into the radial movement of the slider. The mechanical force amplification effect is generated through the included angle of the slide rail, allowing the locking block to reliably retract with a smaller pushing force, reducing the user's hand burden, and improving the sensitivity and stability of locking / unlocking.

[0006] Furthermore, the front end of the drive unit is provided with a fixing post, and a return spring is sleeved on the fixing post. A limiting groove is provided on the inner wall of the mounting base, and the other end of the return spring abuts against the limiting groove. With the return spring sleeved on the fixing post at the front end of the drive unit, after disassembly, the return spring automatically pulls the push block and the telescopic part back to their initial positions, eliminating the need for manual reset and improving ease of use and efficiency. The return spring always applies a preload to the telescopic part, ensuring that the locking block tightly adheres to the lint roller when not pushed, preventing loosening or slippage during rolling and thus ensuring the stability of the cleaning process.

[0007] Furthermore, the drive unit is also provided with a receiving groove for accommodating the telescopic part, and the slide rail is located on the side walls of the receiving groove. The receiving groove provides a clear spatial outline for the telescopic part, and the slide rail is located on the side walls of the groove to ensure that the slider slides only in a predetermined direction, eliminating lateral swaying or shaking and improving the movement accuracy of the locking block. The telescopic part is completely enclosed in the receiving groove, consistent with the outer contour of the housing, avoiding the exposure of the mechanism and increasing the size of the housing; the overall design is flatter and more integrated, which is beneficial for handle grip and aesthetic appearance.

[0008] Furthermore, the receiving groove is provided with a positioning groove for positioning and installing the slider. The positioning groove provides a precise installation position for the slider, preventing the slider from shifting during assembly or use, thereby ensuring that the slide rail and the slider always maintain an optimal fit. The slider only needs to be guided along the positioning groove to complete the initial positioning, without the need for additional clamps or complicated adjustments, significantly improving assembly efficiency and reducing assembly errors caused by improper manual operation.

[0009] Furthermore, the number of slide rails is at least two, and the number of sliders matches the number of slide rails. Two or more parallel slide rails can prevent the telescopic part from tilting or overturning during the pushing process, ensuring that the locking block always moves in a straight line along the predetermined trajectory, thus improving the overall motion accuracy.

[0010] Furthermore, the mounting base is provided with a sliding groove for mounting the push unit, and a fixed rim is provided around the inner wall of the sliding groove inside the mounting base. The drive unit has locking blocks on both sides for engaging with the fixed rim. The sliding groove on the mounting base provides a clear movement channel for the push unit, allowing it to slide back and forth only in a predetermined direction, eliminating lateral or rotational degrees of freedom and improving the stability and repeatability of the mechanism's movement. After the locking blocks on both sides of the drive unit engage with the fixed rim, the push unit achieves instantaneous positioning and locking, allowing for a "one-click" installation that is simple, secure, and eliminates the need for screws or additional fasteners.

[0011] Preferably, the outer casing is provided with a telescopic hole, and the locking block on the telescopic part passes through the telescopic hole and rotates and engages with the lint roller. The locking block protrudes from the telescopic hole, allowing visual inspection to determine whether the locking block is fully extended and engaged within the roller, avoiding a "partially loose" state and improving the reliability of use and maintenance. The telescopic hole confines the movement of the locking block within a predetermined channel; the locking block can only extend and retract along the direction of the hole, preventing jamming or misalignment due to skewness and ensuring a constant concentric fit with the roller bushing.

[0012] The advantages of this invention are as follows: Traditional lint roller replacements often rely on prying open a large, thick plastic sheet or pressing down on the clips, which is laborious and provides a poor feel. This invention features a dedicated pushing block at the other end of the outer shell, linked to the telescopic part. A single linear pushing motion disengages the telescopic part from the rotating engagement of the lint roller, allowing the roller to quickly separate from the outer shell. The operation requires minimal effort, making it easy for the elderly and children to replace; the pressure and displacement are precisely controlled, allowing the user to clearly perceive the "positioning."

[0023] like Figure 1-5The image shows an embodiment of a replaceable lint roller according to this invention. It includes a housing 1 for mounting the lint roller. One end of the housing 1 has a connecting shaft 11 that rotatably engages with the lint roller, and the other end has a push block 2. The push block 2 is linked to a telescopic part 3 that rotatably engages with the lint roller. The push block 2, through a pushing action, disengages the telescopic part 3 from the lint roller, allowing the lint roller to separate from the housing 1. Traditional lint roller replacements often rely on prying open a large, thick plastic sheet or forcefully pressing the clips, which is laborious and provides a poor feel. This invention features a dedicated push block 2 at the other end of the housing 1, linked to the telescopic part 3. A single linear pushing action disengages the telescopic part 3 from the lint roller, allowing the roller to quickly separate from the housing 1. The operation requires minimal effort, making it easy for the elderly and children to replace the lint roller; the force and displacement are precisely controlled, allowing the user to clearly perceive the "position."

[0024] The housing 1 is provided with a mounting base 4, and a pushing cavity 41 is formed between the mounting base 4 and the housing 1. The pushing block 2 includes a pushing part 21 located outside the mounting base 4 and a driving part 22 extending into the pushing cavity 41. The driving part 22 is provided with an inclined slide rail 222. The telescopic part 3 includes a locking block 31 for engaging with the lint roller and a slider 32 slidably connected to the slide rail 222. The pushing block 2, through a pushing action applied to the pushing part 21, causes the slider 32 on the telescopic part 3 to slide along the slide rail 222, thereby causing the locking part to retract into the pushing cavity 41, separating the lint roller from the housing 1. The pushing cavity 41 between the mounting base 4 and the housing 1 defines the movement space of the pushing block 2, allowing the pushing force to be concentrated and transmitted to the driving part 22. The stroke length and force are easy to design and adjust, ensuring a consistent feel for each replacement operation and preventing incomplete locking due to overshoot or undershoot. The inclined slide rail 222 on the drive unit 22 decomposes the linear thrust of the push unit 21 into the radial movement of the slider 32. The mechanical force amplification effect is generated by the included angle of the slide rail 222, so that the locking block 31 can reliably retract under a small thrust, reducing the burden on the user's hand, while improving the sensitivity and stability of locking / unlocking.

[0025] The outer shell 1 can be an integral structure set with the handle, or the external handle can be fixedly connected to the outer shell by means of plug-in, bolt connection, snap-on connection, etc.

[0026] The drive unit 22 has a fixed post 223 at its front end, and a return spring 224 is sleeved on the fixed post 223. The mounting base 4 has a limiting groove 42 on its inner wall, and the other end of the return spring 224 abuts against the limiting groove 42. With the return spring 224 sleeved on the fixed post 223 at the front end of the drive unit 22, after disassembly, the return spring 224 automatically pulls the push block 2 and the telescopic part 3 back to their initial positions, eliminating the need for manual reset and improving ease of use and efficiency. The return spring 224 always applies a preload to the telescopic part 3, ensuring that the locking block 31 fits tightly against the lint roller when not pushed, preventing loosening or slippage during rolling and thus ensuring the stability of the cleaning process.

[0027] The drive unit 22 is also provided with a receiving groove 221 for accommodating the telescopic part 3, and the slide rail 222 is provided on both side walls of the receiving groove 221. The receiving groove 221 provides a clear spatial outline for the telescopic part 3, and the slide rail 222 is provided on both side walls of the groove to ensure that the slider 32 slides only in a predetermined direction, eliminating lateral swaying or shaking, and improving the movement accuracy of the locking block 31. The telescopic part 3 is completely enclosed in the receiving groove 221, which is consistent with the outer contour of the housing, avoiding the increase of the size of the outer shell 1 by exposing the mechanism; the overall design is flatter and more integrated, which is beneficial for handle grip and appearance.

[0028] The receiving groove 221 is provided with a positioning groove 225 for positioning and installing the slider 32. The positioning groove 225 provides a precise installation position for the slider 32, preventing the slider 32 from shifting during assembly or use, thereby ensuring that the slide rail 222 and the slider 32 always maintain the best fit. The slider 32 only needs to be guided along the positioning groove 225 to complete the initial positioning, without the need for additional clamps or complicated adjustments, which significantly improves assembly efficiency and reduces assembly errors caused by improper manual operation.

[0029] The number of slide rails 222 is at least two, and the number of sliders 32 matches the number of slide rails 222. Two or more parallel slide rails 222 can prevent the telescopic part 3 from tilting or overturning during the pushing process, ensuring that the locking block 31 always moves in a straight line along the predetermined trajectory, thereby improving the overall motion accuracy.

[0030] The mounting base 4 is provided with a sliding groove 43 for mounting the push unit 21. A fixed perimeter 44 surrounds the inner wall of the sliding groove 43 inside the mounting base 4. The drive unit 22 has locking blocks 226 on both sides for engaging with the fixed perimeter 44. The sliding groove 43 on the mounting base 4 provides a clear movement channel for the push unit 21, allowing it to slide back and forth only in a predetermined direction, eliminating lateral or rotational degrees of freedom and improving the stability and repeatability of the mechanism. After the locking blocks 226 on both sides of the drive unit 22 engage with the fixed perimeter 44, the push unit 21 achieves instantaneous positioning and locking. Installation is "one-click in place," simple and secure, eliminating the need for screws or additional fasteners.

[0031] The outer casing 1 is provided with a telescopic hole 12, and the locking block 31 on the telescopic part 3 passes through the telescopic hole 12 and rotates and engages with the lint roller. The locking block 31 is exposed in the telescopic hole 12, and it can be visually determined whether the locking block 31 is fully extended and engaged in the roller, avoiding a "partially loose" state and improving the reliability of use and maintenance. The telescopic hole 12 restricts the movement of the locking block 31 within a predetermined channel. The locking block 31 can only extend and retract along the direction of the hole, avoiding jamming or misalignment caused by skew, and ensuring that it is always concentrically fitted with the roller bushing.

[0032] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
