[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a quick-release lint remover, including a horizontal shell and two side arms, with a roller shaft arranged between the two side arms. The feature is that the arm has a slot for inserting the roller shaft, the slot being U-shaped with the U-shape facing downwards and forming a groove at the bottom for the roller shaft to enter and exit. The arm has a blocking member that can move along the X-axis and can partially or completely block the groove. The arm also has a driving member that can move along the Z-axis. The driving member is linked with the blocking member under external force. The blocking member and / or the driving member have inclined lines / surfaces for contact. The inclined lines / surfaces are located on the XZ axial plane. During the movement of the driving member, the direction of movement of the blocking member is changed by pushing with the inclined lines / surfaces. The arm has a reset member that resets the blocking member after movement.

[0006] A further preferred embodiment of this utility model is as follows: the blocking member is provided with an inclined groove, and the driving member is provided with a pin below it. The pin is inserted into the inclined groove, which is located on the XZ axial plane. The pin moves along the inclined groove during the downward movement of the Z axial direction, and the pin pushes the inclined groove to make the blocking member move.

[0007] A further preferred embodiment of this utility model is: the blocking member is provided with an arc-shaped part, the arc opening of the arc-shaped part faces away from the U-shaped groove, and the arc-shaped part is used to support the roller shaft.

[0021] The preferred embodiments of the present invention will be described in detail below 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.

[0022] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0023] This embodiment mainly describes the quick-release lint remover, as detailed below: like Figures 1-9As shown, the quick-release lint roller includes a horizontal shell 3 and a pair of arms 6. The two arms 6 are fixedly mounted on both sides of the horizontal shell 3 by a connector. A roller shaft 5 is detachably mounted between the two arms 6. Specifically, each arm 6 is provided with a slot 8 for inserting the roller shaft 5. The slot 8 is U-shaped, with the U-shape facing down, forming a groove at the bottom for the roller shaft 5 to enter and exit. This allows the roller shaft 5 to be directly inserted or removed from below. To prevent the roller shaft 5 from accidentally coming out of the groove during normal use and to allow for quick release when replacement is needed, this embodiment provides a locking and unlocking mechanism inside the arm 6, consisting of a blocking component 7, a driving component 4, and a reset component.

[0024] The connector is rotatably provided with a handle 1 for the user to hold. Among the two arms 6, the surface of the arm 6 away from the handle 1 is a hollow shell. The cavity inside is used to accommodate the locking and unlocking mechanism. The slot 8 penetrates the inner and outer walls of the arm 6. Its U-shaped structure provides stable radial support for the roller shaft 5. The slot is located at the bottom of the U-shape and is the only channel for the roller shaft 5 to enter and exit.

[0025] like Figure 4 As shown, the blocking member 7 is a part that directly controls the opening and closing of the slot. It is limited in the internal cavity of the boom 6 and can move back and forth along the horizontal X-axis. Specifically, the blocking member 7 can be divided into a linkage part 11, an extension part 12 and a blocking part 13.

[0026] The linkage 11 is connected to the drive component 4. The linkage 11 is provided with a slanted groove 10 located on the XZ axial plane. The linkage 11 realizes power transmission and direction conversion through the slanted groove 10.

[0027] The extension 12 extends from the linkage 11 to one side of the slot 8. Throughout the movement, the extension 12 never overlaps with the slot 8 above, thus avoiding interference with the roller shaft 5.

[0028] The blocking part 13 is located below the extension 12 and is used to lock or unlock the roller shaft 5.

[0029] When the blocking component 7 is in different working states, each part plays a different role: When the blocking member 7 is in the locking position: the blocking part 13 moves to directly below or to the side below, partially or completely blocking the slot, thereby preventing the roller shaft 5 from falling.

[0030] When the blocking member 7 is in the unlocked state: the blocking member 7 moves along the X-axis under the drive of the driving member 4, so that its blocking part 13 moves away from the slot, opens the channel, and allows the roller shaft 5 to enter and exit through the slot.

[0031] Furthermore, an arc-shaped part 15 is provided on the upper surface of the blocking part 13. The arc opening of the arc-shaped part 15 faces upward and away from the U-shaped groove. When the roller shaft 5 is installed in the slot 8, the arc-shaped part 15 can play a supporting and limiting role, so that the roller shaft 5 is subjected to more uniform force and the operation is more stable.

[0032] The lower surface of the blocking part 13 is provided with a guide part 14, which is arranged in an arc shape. When the user installs the roller from below, the roller shaft 5 will first contact this guide part 14 during the process of inserting into the slot. If the roller shaft 5 is pushed upward, the guide part 14 will convert the upward thrust into a thrust on the blocking part 7 in the X direction, causing it to retract automatically, realizing "buttonless" installation, which is very convenient.

[0033] A drive unit 4 is provided above the blocking member 7. The drive unit 4 is located in the arm 6 away from the handle 1 and can move up and down along the vertical Z-axis. A button 19 is provided at the top of the drive unit 4. The button 19 is exposed on the arm 6 for easy pressing by the user.

[0034] A pin 9 is fixedly installed below the driving component 4. The pin 9 is inserted into the inclined groove 10 of the blocking component 7. The driving component 4 (moving in the Z direction) and the blocking component 7 (moving in the X direction) are linked by the "pin 9-incline groove 10" mechanism.

[0035] like Figure 5 As shown, a reset component is provided on the drive component 4. When the external force is removed, the entire mechanism is restored to the initial locked state. Preferably, the reset component is a compression spring 18. The two ends of the compression spring 18 abut against the drive component 4 and the transverse shell 3 respectively. Specifically, a groove 16 is provided on the drive component 4, and a boss 17 is provided inward on the transverse shell 3 corresponding to the position of the groove 16. One end of the compression spring 18 abuts against the top of the groove 16, and the other end abuts against the boss 17. The extension and retraction direction of the compression spring 18 is consistent with the movement direction of the drive component 4, which is the Z-axis axial movement.

[0036] The quick-release lint roller is also equipped with a dust cover 2. When the quick-release lint roller is not in use, the dust cover 2 can block external dust.

[0037] Working principle: Normal use (locked state) Without external force, the spring force of the compression spring 18 pushes the drive member 4 upward to its highest position. At this time, the pin 9 at the lower part of the drive member 4 is located at the upper end of the inclined groove 10. Through the transmission of the inclined groove 10, the blocking member 7 is pushed to one end in the X-axis direction under the force of the compression spring 18, so that its blocking part 13 is located below the slot of the slot 8, forming a blockage, and the roller shaft 5 is safely restricted in the slot 8.

[0038] Disassembling the roller shaft (unlocking process) When the roller shaft 5 needs to be replaced, the user presses the button 19 downwards, causing the entire drive component 4 to overcome the elastic force of the compression spring 18 and move downwards along the Z-axis. As the drive component 4 moves downwards, its pin 9 slides along the inclined groove 10 on the blocking component 7. Since the inclined groove 10 is inclined, the pin 9 will exert a pushing force perpendicular to the inclined plane on the groove wall of the inclined groove 10 while moving downwards vertically. This pushing force can be decomposed into a horizontal component force. This horizontal component force drives the blocking component 7 to move along the X-axis, causing its blocking part 13 to retract from the blocking position. When the blocking part 13 of the blocking component 7 is completely removed from the slot opening of the slot 8, the slot opening is fully opened. At this time, the roller shaft 5 loses its support and automatically falls from the slot opening under the action of gravity, realizing quick disassembly.

[0039] Install roller shaft There are two ways to install a new roller: Direct installation: Align the two ends of the roller shaft 5 with the slots that are already in the unlocked state (i.e., continuously press button 19), and push them upwards.

[0040] Guided installation: Even when the mechanism is locked, the user can directly push the roller shaft 5 upward from below, aligning it with the slot. The roller shaft 5 will first contact the guide part 14 on the lower surface of the blocking part 13. Continuing to push upward, the roller shaft 5 forces the blocking part 7 to move in the X direction through the guide part 14, automatically making way and allowing the shaft to slide smoothly into the slot 8. Once the roller shaft 5 passes the blocking part 13, the blocking part 7 will quickly spring back to the locked position under the action of the compression spring 18, completing the installation. This process does not require pressing the button 19, making it more convenient.
