Description

Technical Field

[0001] This invention relates to the field of lint rollers, and more specifically to a deformable lint roller. Background Technology

[0002] Lint rollers are widely used in daily household cleaning as a cleaning tool. They use adhesive on the surface of the roller to stick and collect lightweight debris such as dust and hair. Compared with sweeping, they effectively avoid problems such as dust and hair tangling. Lint rollers are easy to use as they are used and can be removed immediately without the need for maintenance or cleaning.

[0003] Patent 202311260685.9 discloses a quick-release lint roller. By providing a sleeve part on the outer shell that rotates relative to the left end of the lint roller, and providing a telescopic component on the outer shell that rotates relative to the right end of the lint roller, the telescopic component can be moved with one hand to disengage from the right end of the lint roller, thereby detaching the lint roller from the outer shell and achieving quick release of the lint roller. The lint roller includes a lint roll and a left paper cover and a right paper cover respectively located at both ends of the lint roll. The rotating shaft is located on the side of the left paper cover and the right paper cover away from the lint roll. This patent solves the problem of how to quickly install and remove lint rollers, making them relatively convenient to use. However, the inner side of the lint roller roll is only supported by the paper covers at both ends and the cardboard inside the roll. During storage, transportation, and use, the lint roller roll may collapse and deform inward under stress, affecting its rolling and cleaning. Furthermore, in actual operation, the quick-release structure requires removing the left and right paper covers from the old lint roller roll and installing them onto the new roll, which is cumbersome. If consumers accidentally discard the left and right paper covers when replacing the roll, the lint roller cannot be used with other lint roller rolls, making the product still somewhat defective.

[0004] Therefore, there is still room for optimization in the replacement and usage structure of lint roller paper, as well as the structure of the lint roller paper itself. Summary of the Invention

[0005] One object of the present invention is to provide a deformable lint roller that solves the above-mentioned problems.

[0006] To achieve the above-mentioned objectives, the present invention is implemented through the following technical solutions: A deformable lint roller includes a lint roller and a roller for supporting the lint roller. The roller has a radially deformable structure and can switch between a first state and a second state. In the first state, the cross-sectional area of ​​the roller increases, so that its outer surface fits against the inner surface of the lint roller to fix the lint roller. In the second state, the cross-sectional area of ​​the roller decreases, so that its outer surface disengages from the lint roller to facilitate the removal of the lint roller. During installation, the roller is in the second state, the lint roller is placed on the roller, and then the roller is switched to the first state to fix the lint roller on the roller. During removal, the roller is switched from the first state to the second state, and then the lint roller is removed or the lint roller falls off by gravity. By incorporating rollers on the lint roller to provide overall support, the lint roller is prevented from collapsing and deforming inwards due to hard protrusions such as stones or uneven ground, which would affect its subsequent use. Furthermore, even if the lint roller deforms inwards during production, storage, or transportation, the rollers can still provide support and restore it to its cylindrical shape. Alternatively, even without the rigid cardboard support on the inside of the lint roller, the rollers can still be used, effectively reducing production costs. Additionally, the radially deformable rollers allow for easy installation and removal of the lint rollers by adjusting their size, enabling automatic removal by gravity and eliminating the need for manual handling of the soiled lint rollers.

[0007] Preferably, the roller includes at least one support member that can move radially along the roller and a guide member disposed on the roller to guide the radial movement of the support member; a mating structure is provided between the guide member and the support member, so that the movement of the guide member or the movement of the support member along the guide member can be converted into radial displacement of the support member, thereby changing the outer diameter of the roller. By providing a mating structure between the guide member and the support member, controlling the movement of the guide member indirectly drives the movement of the support member or directly controls the movement of the support member along the guide member. The mating structure converts the direct or indirect movement of the support member into radial displacement, thereby changing the outer diameter of the roller without touching the lint roller.

[0008] Preferably, the roller includes a core and multiple support members movably arranged circumferentially along the core; multiple guide members are provided on the outer periphery of the core, each guide member corresponding to one of the support members; when there is relative movement between the support member and the core, the mating structure between the guide member and the support member causes the support member to undergo radial displacement, thereby changing the outer diameter of the roller. The core allows the roller to rotate circumferentially when combined with a handle or similar structure, enabling the lint roller to clean the surface to be cleaned, and also allows for more synchronized movement of the support members.

[0009] Preferably, the mating structure includes any one of the following: a boss, a cam, a guide groove, a screw, a magnet assembly, or a linkage mechanism.

[0010] Preferably, the roller also includes a limiting mechanism and an elastic element. The limiting mechanism keeps the roller in a first state with an increased cross-sectional area. When the roller and the lint roller contact the surface to be cleaned, the contact force exerted by the surface to be cleaned on the roller and the lint roller will not change the cross-sectional area of ​​the roller. The lint roller can be stably installed on the roller and rotate synchronously with the roller to clean the surface to be cleaned. The elastic force of the elastic element causes the support to automatically move to a second state with a reduced cross-sectional area after the limiting is released, and keeps the roller in the second state. This allows the lint roller to automatically fall off from one end of the roller under its own weight, eliminating the need to touch the used lint roller by hand. Also, when installing the lint roller, the lint roller will not move the support to change the outer diameter of the roller during its axial movement along the roller. The installation of the lint roller is smoother. The lint roller is installed on the roller as a whole, and the size of the roller is adjusted after the lint roller is installed to complete the installation.

[0011] Preferably, the roller is provided with an anti-slip element, which increases the resistance to movement between the lint roller and the roller, preventing the lint roller from moving axially or rotating circumferentially relative to the roller. The outer surface of lint rollers is sticky. When the lint roller comes into contact with the surface to be cleaned, the stickiness creates resistance to the rotation of the lint roller. If the surface of the roller or the inner side of the lint roller is relatively smooth, the resistance created by the stickiness causes relative rotation between the lint roller and the roller, affecting the rotation and movement of the roller and the cleaning effect of the lint roller on the surface to be cleaned. When cleaning uneven surfaces such as clothing or pets, if there is an angle between the direction of the force applied by the hand and the direction of movement of the roller and lint roller, or if the roller and lint roller do not move in a direction perpendicular to their axis, axial slippage can easily occur between the lint roller and the roller. This causes the end part of the lint roller to detach from the roller and form wrinkles that surround the end side of the roller, affecting the subsequent rotation of the lint roller and even affecting the automatic disassembly of the lint roller under gravity. The setting of anti-slip components, such as anti-slip mats, textures on the outer surface of the roller, or rubber bands, increases the frictional resistance between the roller and the lint roller to overcome the above defects and achieve stable rolling of the lint roller and hand-free disassembly.

[0012] Preferably, the cross-section of the support member is arc-shaped or fan-shaped. In the first state, the centers of the circles of each support member and the core are located at the same point on the same cross-section, and the roller formed by the support members creates a concentric cylinder with a diameter different from that of the core. When the support member moves to the second state, the support members on opposite sides of the core move towards each other, and the centers of the corresponding support members move in opposite directions, so that the fan-shaped areas formed by the connection between the two corresponding support members and their centers have overlapping areas. By keeping the roller in the first state in a perfect circle, and with the support members and the core being concentrically arranged, the lint roller can be tensioned into a perfect circle, making the lint roller's rolling cleaning smoother.

[0013] Preferably, the lint roller is composed of a ring-shaped base paper with an adhesive layer on the outside, giving it overall flexibility. The lint roller has a central cavity, allowing it to deform and fold into the cavity to close it. Compared to traditional lint rollers, eliminating the inner cardboard effectively reduces production costs. Furthermore, the folding design reduces the storage and transportation size of the lint roller, further lowering costs. When used with a resizable roller, the roller stretches and expands the lint roller, ensuring it remains unaffected by folding and the absence of a rigid board, allowing it to roll smoothly.

[0014] Preferably, the cavity of the lint roller is opened, and the roller is inserted. The roller abuts against the lint roller and deforms outward until the entire lint roller is fitted around the outer circumference of the roller. This mating structure increases the outer diameter of the roller, and each of the support members moves radially outward to abut against the lint roller and tension and support it. Traditionally, lint rollers and lint removers are generally tightly spaced, and even slight deformation of the lint roller can affect the installation of both. However, the variable diameter structure of the roller increases the installation gap between the roller and the lint roller in the second state, effectively improving the installation efficiency of the lint roller and enabling hands-free removal of the lint roller.

[0015] Preferably, the system also includes a support bracket with a connecting seat. The column core is connected to the connecting seat and can rotate circumferentially or move axially relative to the connecting seat. The connecting seat has a lifting groove, and one end of each support member is limited and installed on the lifting groove. During the rotation or movement of the column core, the support member will not move axially, but can only move radially inward or radially outward along the lifting groove. By using the connecting seat and lifting groove to limit the axial movement of the support member, the support member can only move radially inward and outward, making the size change of the roller smoother.

[0016] Preferably, the outer end of the lifting groove is open, the support member is inserted into the lifting groove from the outer periphery of the connecting seat, and the elastic members are respectively installed at both ends of the roller. The elastic force of the elastic members applies force towards the axis of the roller to prevent the support member from disengaging from the lifting groove. Synchronous circumferential positioning of each support member is achieved through the elastic members, giving the elastic members both positioning and driving functions for the support members, simplifying the installation and limiting structure of the support members and elastic members.

[0017] The advantages of this invention are as follows: By incorporating a roller on the lint roller that provides overall support, the lint roller is prevented from collapsing and deforming into the inward cavity due to hard protrusions such as stones or uneven ground during use, thus avoiding impact on subsequent use. Furthermore, even if the lint roller deforms inward during production, storage, or transportation, the roller can still provide support and restore it to its cylindrical shape. Alternatively, even without the rigid cardboard support on the inside of the lint roller, the roller can still be used with it, effectively reducing the production cost of the lint roller. Additionally, the roller's radially deformable structure allows for easy installation and removal of the lint roller by changing its size, enabling automatic removal by gravity and eliminating the need for manual contact with the soiled lint roller.

[0055] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the process of how the present invention uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0056] This invention uses certain terms to refer to specific components. Those skilled in the art will understand that this specification and claims do not distinguish components by differences in name, but rather by differences in function. It should be noted that, unless otherwise specified, when a component is described as "provided with," "located on," or "located on" another component, it can mean directly provided with or located on another component, or it may include a component in between; it can be an integral structure or a separate structure. When a component is described as "connected" to another component, it can be a direct connection or a connection through a component in between; it can be an integral connection, a separate connection, or a contact fit. When a component is described as "located on another component," it does not necessarily mean that the component is located above or on top of the other component; it can be in other positions. The terms "above," "below," "left," "right," "high," "low," and similar expressions used herein are based on the normal placement state of the product and are merely for illustrative purposes. The term "multiple" used herein refers to two or more items. The terms "vertical" and "horizontal" used in this article refer to a state that is roughly vertical or roughly horizontal within a reasonable margin of error, and do not necessarily have to be extremely precise.

[0057] A deformable cleaning device includes a cleaner 1 and a wiping material 4. The cleaner 1 includes a handle 2 and a bracket 3. The wiping material 4 is detachably mounted on the bracket 3. The wiping material 4 can rotate relative to the handle 2 or the bracket 3 for cleaning. The wiping material 4 is configured as a hollow cylindrical sleeve. The bracket 3 is provided with a roller 5. The wiping material 4 is sleeved on the roller 5 and supported by the roller 5 to prevent the wiping material 4 from deforming or sinking in the direction away from the wiping surface 6', so as to keep the wiping surface 6' in close contact with the surface to be cleaned.

[0058] like Figure 1-38 A deformable lint roller is described in this embodiment. The cleaner 1 is configured as a lint roller 1', and the wiping material 4 is configured as a lint roller 4'. The outer periphery of the lint roller 4' is provided with an adhesive layer 6 to form a wiping surface 6'. The wiping surface 6' is cleaned by rolling to remove hair, dust and other debris.

[0059] like Figure 3-4Traditional lint rollers 4' are typically set up by wrapping long strips of tape around a cardboard tube 7, with pre-defined intervals along the length to allow the outermost layer of tape to be torn off after cleaning. Unused tape is exposed on the outermost side of the lint roller 4'. The lint roller 4' is installed and removed using a snap-on method. For example, plugs are installed on both sides of the cardboard tube 7, and the plugs are aligned with the mounting parts of the lint roller 1'. To save costs, the plugs are short and cannot provide support for the inner cavity of the cardboard tube 7. The lint roller 4' relies solely on the rigidity of the inner cardboard tube 7 for support. Although the support provided by the plugs at both ends and the lint roller 1' is sufficient for cleaning flat surfaces, and the lint roller 4' does not collapse into the inner cavity, the strength of the cardboard tube 7 is limited when the lint roller 4' is subjected to localized stress in the middle. The lint roller 4' is prone to collapse into the inner cavity, affecting subsequent use.

[0060] In this embodiment, the bracket 3 is provided with a roller 5, which can be inserted into the hollow cavity of the lint roller 4' to provide support for the inner side of the lint roller 4'. During use, the roller 5 and the cardboard tube 7 together provide support for the tape. Compared with the cardboard tube 7 supporting alone, the roller 5 has better rigidity and better support effect.

[0061] Based on the support provided by the roller 5, the lint roller 4' in this embodiment can also be configured to consist of only one or more turns of base paper 8, with an adhesive layer 6 on the outer side of the base paper 8 and no cardboard tube on the inner side of the base paper 8, thereby reducing the cost of the lint roller 4'. Furthermore, traditional lint rollers 4' must be protected from compression during production, storage, and transportation to prevent deformation. Figure 4When a traditional lint roller 4' is compressed, it collapses and deforms into the cavity, creating at least two creases on the inner cardboard tube 7. Although the lint roller 4' can recover its shape under pressure, the cardboard tube 7 and the lint roller 4' are difficult to restore to their initial circular shape due to the creases and the rigidity of the material itself. If there is no support on the inner side, the cross-section of the lint roller 4' is roughly almond-shaped, with the two creases protruding outwards, and the sides corresponding to the creases slightly collapsing inwards. A typical support 3 is set with the initial... The cylindrical inner side of the cardboard tube 7 makes it difficult to install the lint roller 4', which recovers under pressure, on the bracket 3. Even if the lint roller 4' can be installed, the protrusion at the crease will affect the rotation or rolling of the lint roller 4' relative to the surface to be cleaned. Of course, under greater external force and longer compression deformation time, the cardboard tube 7 may also break and become irrecoverable. Therefore, the cavity in the center of the lint roller 4' requires more space during storage and transportation, and it is necessary to avoid the lint roller 4' from being crushed after stacking and packaging. In this embodiment, the lint roller 4' only has a base paper 8 and an adhesive layer 6. The rigidity of the base paper 8 is weaker than that of the cardboard tube 7. After being deformed under pressure, the base paper 8 can still recover to its approximate initial shape. Moreover, because the base paper 8 itself is relatively soft, after the base paper 8 is fitted onto the roller 5, it can recover to its initial perfect circle under the support of the roller 5.

[0062] like Figure 5 In this embodiment, the lint roller 4' has only one layer of base paper 8, which is wrapped into a cylindrical body. The base paper 8 is made of flexible, thin paper. The outer peripheral surface of the base paper 8 is provided with an adhesive layer 6, which is formed by covering with heat-sensitive adhesive. The outer periphery of the adhesive layer 6 is then covered with a thin film 9, such as plastic film or release paper, to prevent unused adhesive layer 6 from sticking to foreign objects. With this structure, the unused lint roller 4' is installed before each cleaning, and the outer film 9 is peeled off for cleaning. After cleaning, the lint roller 4' is removed. Compared with the traditional multi-layer structure of the lint roller 4', the action of the outermost layer of used tape is eliminated, and the user does not need to touch the dirty tape, making it more hygienic.

[0063] like Figure 6 In this embodiment, the lint roller 4' has a cavity 10 at its center. The lint roller 4' can deform and fold into the cavity 10 to close the cavity 10. After production, the lint roller 4' can be stored and transported by compressing and deforming, thereby saving storage and transportation space. Moreover, there is no need to specially control the pressure condition of the lint roller 4'. The lint roller 4' can be packaged in a bundle or package like tissue paper to save a lot of space.

[0064] To facilitate the installation of the deformable lint roller 4', such as Figure 7-9 The roller 5 has a radially deformable structure, capable of switching between a first state A and a second state B; in the first state A, as... Figure 9The cross-sectional area of ​​roller 5 is increased so that its outer surface fits against the inner surface of lint roller 4' to fix lint roller 4'; in the second state B, as Figure 7 Alternatively, the cross-sectional area of ​​roller 5 is reduced so that its outer surface is separated from the lint roller 4', making it easier to remove the lint roller 4'. During installation, roller 5 is in the second state B, and the lint roller 4' is placed on roller 5. Then, roller 5 is switched to the first state A to fix the lint roller 4' on roller 5. During disassembly, roller 5 is switched from the first state A to the second state B, and then the lint roller 4' is removed or dropped by gravity.

[0065] In this embodiment, to accommodate the improved lint roller 4', the outer diameter of the roller 5 in the first state A is adapted to the inner diameter of the lint roller 4' which has returned to a cylindrical shape, or the outer diameter of the roller 5 is slightly larger than the inner diameter of the lint roller 4', so as to support the easily deformable lint roller 4' and unfold it into a perfect circle. The lint roller 4' itself has a certain degree of tear resistance, so even if the outer diameter of the roller 5 is slightly larger than the inner diameter of the lint roller 4', the lint roller 4' will not be torn, and the fit between the lint roller 4' and the roller 5 is better. In the second state B, the outer diameter of the roller 5 is smaller than the inner diameter of the lint roller 4', which facilitates the installation and removal of the lint roller 4'. Before installation, the roller 5 is switched to the second state B with a smaller outer diameter. One lint roller 4' is taken and unfolded into a pre-installation state with a larger cavity, such as... Figure 7 In this state, the lint roller 4' is irregularly shaped like an oval or almond. The end of the pre-installed lint roller 4' is fitted onto one end of the roller 5. The lint roller 4' is thin and highly flexible. The outer diameter of the roller 5 is small, so the lint roller 4' can be easily moved and fitted onto the roller 5. After the lint roller 4' is installed, the roller 5 is switched to the first state A with a larger outer diameter. As the outer diameter of the roller 5 increases, the lint roller 4' is stretched open and eventually kept in a state with a perfect circle in cross-section, which facilitates the rotation of the lint roller 4' for cleaning. When cleaning the surface to be cleaned, the lint roller 4' makes contact with the surface in a line-to-line manner. With the support of the roller 5, the contact line of the lint roller 4' is a continuous straight line, and any contact line of the lint roller 4' during rolling remains parallel to the axis of the lint roller 4' or the roller 5. This avoids problems such as insufficient inner support of the lint roller 4' or local protrusions or depressions on the surface caused during production, transportation, and storage, which could result in areas that cannot be cleaned during rolling cleaning, or the lint roller 4' having an irregular shape or not rolling smoothly.

[0066] In this embodiment, the outer diameter of the roller 5 can be changed in a variety of ways, such as splitting the roller 5 into multiple parts, with each part moving to change the overall cross-sectional size of the roller 5; or adjusting the cross-sectional size of the roller 5 by means of air pressure, hydraulic pressure, etc.

[0067] The first method of changing the outer diameter in this embodiment is configured such that the roller 5 includes at least one support member 11 that can move radially along the roller 5 and a guide member 12 disposed on the roller 5 to guide the radial movement of the support member 11; a matching structure 13 is provided between the guide member 12 and the support member 11, so that the movement of the guide member 12 or the movement of the support member 11 along the guide member 12 can be converted into the radial displacement of the support member 11 to change the outer diameter of the roller 5.

[0068] Preferably, the roller 5 includes a core 14 and a plurality of support members 11 arranged movably along the circumference of the core 14; a plurality of guide members 12 are provided on the outer periphery of the core 14, and the guide members 12 correspond one-to-one with the support members 11; when the support members 11 and the core 14 move relative to each other, the mating structure 13 between the guide members 12 and the support members 11 causes the support members 11 to generate radial displacement, thereby changing the outer diameter of the roller 5.

[0069] Specifically, such as Figure 10-12 The core 14 is mounted on the bracket 3. Multiple support members 11 are provided and staggered around the outer periphery of the core 14. External force causes the core 14 to move relative to the support members 11, or vice versa, changing the radial distance between the support members 11 and the core 14. This allows for the switching of the support members 11's opening and retraction dimensions. The outer surfaces of each support member 11 are attached to the inner side of the lint roller 4' to form the roller 5. In this embodiment, the core 14 is cylindrical, and the guide member 12 is located around the core 14 and corresponds to the arrangement of the support members 11. The support members 11 are arc-shaped or fan-shaped, and the core 14 and the support members 11 are connected or cooperate with each other through the guide member 12.

[0070] like Figure 11 In the second state B, the inner side of the support member 11 abuts against the guide member 12. The size of the roller 5, composed of all the support members 11, is much smaller than the inner size of the lint roller 4'. Even if the lint roller 4' is not fully unfurled into a perfect circle, it can still be fitted onto the roller 5. When the lint roller 4' is installed as a whole and the support member 11 is still not moving, the lint roller 4' can move freely along the axial and circumferential directions on the roller 5. Figure 11 The relative movement of the core 14 and the support 11 causes the outer diameter of the roller 5 to change. During the movement of the roller 5, each support 11 pushes and opens the lint roll 4' to different positions until the roller 5 moves to the first state A, which is in contact with or approximately in contact with the inner side of the lint roll 4'. The roller 5 provides support for the lint roll 4' on the inner side to prevent the lint roll 4' from collapsing towards the axial position. The multiple support 11 work together to tighten the lint roll 4' circumferentially. Even if there is a gap between adjacent support 11 after the movement, the lint roll 4' under tension has a certain rigidity at the position corresponding to the gap. The rigidity at this position is also stronger than the rigidity when it is not installed or not under the first state A. The gap generated by the support 11 will not affect the rolling cleaning force of the lint roll 4'.

[0071] Preferably, all support members 11 have the same shape, size and structure to facilitate production and installation. The length of each support member 11 is adapted to the length of the lint roller 4', so that each position of the lint roller 4' can be supported by the roller 5. In this embodiment, there are four support members 11, and the arc size of each support member 11 is less than 90°. Taking the lint roller 4' with an inner diameter of 40mm as an example, the support member 11 is divided into four equal parts in an expanded state of 40mm. Then, the side of each support member 11 is cut to form a moving clearance space. The outer surface of each support member 11 is a flat arc surface that can fit with the inner surface of the lint roller 4', so that each support member 11 supports the lint roller 4' to form a perfect circle with an inner diameter of 40mm. Of course, the number, arc size, and diameter of the support members 11 in this embodiment are just examples. The number of support members 11 can also be set to two, three, five, six, or other numbers. The arc size can also be adjusted according to the number. The diameters of the lint roller 4' and the roller 5 can also be freely adjusted according to different needs, as long as the roller 5 can support and tension the lint roller 4'.

[0072] In this embodiment, the length of the roller 5 is not greater than the length of the lint roller 4', so as to prevent the end of the lint roller 4' from extending beyond the outer side of the end of the roller 5 and being squeezed to form wrinkles, which would affect the rotation and disassembly of the lint roller 4'.

[0073] To maintain the circular shape of the roller 5 with its increased outer diameter, the centers of the arcs or fan shapes of each support member 11 are collinear with the center of the core 14 in the first state A, forming concentric cylinders of different diameters. That is, the centers of each support member 11 and the core 14 are located at the same point on the same cross-section. When the support member 11 moves towards the second state B, it moves closer to the core 14, and its center moves further away from the center of the core 14. Figure 13 Taking two or four support members 11 as an example, the support members 11 on opposite sides of the core 14 move towards each other, and the centers of the corresponding support members 11 move in opposite directions, so that the fan-shaped areas formed by the connection between the two support members 11 and their centers have overlapping areas. Furthermore, in order to prevent the support members 11 from obstructing each other during movement, the sides of the connecting leaves on each support member 11 are cut to allow for clearance, so that the sides of the connecting leaves on adjacent support members 11 remain parallel, and each support member 11 can move inward or outward without interfering with each other.

[0074] To achieve synchronized movement of each support member 11, this embodiment uses a control column core 14 to drive the movement of each support member 11. Specifically, the column core 14 is provided with a guide 12, and the inner side of the support member 11 is provided with a mating part 15. The guide 12 and the mating part 15 cooperate to control the axial movement or circumferential rotation of the column core 14 to drive the movement of each support member 11.

[0075] like Figure 10-12 14. The guide 12 is configured as an insert 121, and the mating part 15 is configured as a slide 151. The slide 151 extends along the axial direction of the support 11 and is located on the same plane as the movement direction of the core 14. The slide 151 has a first end and a second end. The distances between the first end and the second end and the axis of the core 14 are different, so that there is an angle between the slide 151 and the core 14. While the core 14 moves along its axial direction, the insert 121 moves in the slide 151 and switches positions between the first end and the second end. To prevent the support member 11 from moving with the column core 14, the bracket 3 is provided with a connecting seat 16. The column core 14 is inserted into the connecting seat 16 and can move axially relative to the connecting seat 16. One end of each support member 11 is limited and installed on the connecting seat 16, so that the axial direction of the support member 11 is fixed with the connecting seat 16. The connecting seat 16 is provided with a lifting groove 17, which extends in the radial direction. When the column core 14 moves axially, the support member 11 will not move in the same direction due to friction under the limiting action of the connecting seat 16. The insert block 121 changes position in the sliding groove 151 and pushes and pulls the support member 11 to open outward or retract inward.

[0076] Preferably, one end of the core 14 extends from the connecting seat 16 to form a control switch 18, or the core 14 is equipped with a control switch 18 extending from the connecting seat 16. By pushing and pulling the control switch 18, the core 14 is moved axially. The outer end of the lifting groove 17 is open, and the support member 11 is inserted into the lifting groove 17 at the outer periphery. The bracket 3 is provided with a round hole 19, and the connecting seat 16 is limited and installed in the round hole 19, so that the outer end of the lifting groove 17 and part of the support member 11 are covered by the bracket 3 to prevent the support member 11 from detaching from the lifting groove 17.

[0077] In this embodiment, the bracket 3 is provided with a buckle 20 surrounding the outer periphery of the column core 14, and the center of the connecting seat 16 is provided with an annular groove 21. The cooperation of the buckle 20 and the annular groove 21 realizes the limited installation of the connecting seat 16. In order to facilitate the rotation and cleaning of the roller 5 and the lint roller 4', the roller 5, the column core 14 and the connecting seat 16 can all rotate relative to the bracket 3. The movement resistance between the lint roller 4' and the surface to be cleaned causes the lint roller 4', the roller 5, the column core 14 and the connecting seat 16 to rotate synchronously. Of course, it is also possible to use a method such as the insertion block 121 being rotatably connected to the column core 14 and the column core 14 being fixedly connected to the bracket 3. In use, the lint roller 4', the roller 5 and the insertion block 121 rotate synchronously relative to the column core 14 and the bracket 3.

[0078] like Figure 15-17The guide 12 is configured as a first hinge 122, and the mating part 15 is configured as a second hinge 152. A pull rod 22 is connected between the first hinge 122 and the second hinge 152. The two ends of the pull rod 22 can rotate relative to the column core 14 and the support member 11, respectively. When the roller 5 is in the second state B, the pull rod 22 is tilted relative to the axis of the column core 14, which controls the axial movement of the column core 14. The position of the first hinge 122 changes, which pulls the pull rod 22 to move and rotate. The pull rod 22 then drives the second hinge 152 and the support member 11 to move. During the movement of the pull rod 22, the tilt angle between it and the column core 14 is changed. By increasing the tilt angle through the movement, the support member 11 moves radially outward and opens.

[0079] To prevent the support member 11 from being reset under force during the cleaning process, a limiting mechanism 23 is provided between the column core 14 and the bracket 3 to prevent the column core 14 from moving axially. Alternatively, in the first state A, the pull rod 22 is kept in a position perpendicular to the axis of the column core 14 and the support member 11 to form the limiting mechanism 23. When the roller 5 is rolled to clean the flat surface to be cleaned, the contact force between the roller 5 and the surface to be cleaned is parallel to the pull rod 22, and the pull rod 22 will not be rotated under force.

[0080] like Figure 18-22 The guide 12 is configured as a first pushing surface 123, and the mating part 15 is configured as a second pushing surface 153. The first pushing surface 123 and the second pushing surface 153 are kept in contact. At least one of the first pushing surface 123 and the second pushing surface 153 is configured as an inclined surface. When the roller 5 is in the second state B, the second pushing surface 153 is located at the lower position of the first pushing surface 123. The control column core 14 moves axially, the first pushing surface 123 moves axially and pushes the second pushing surface 153. Under the limiting installation action of the support 11 and the connecting seat 16 or the bracket 3, the support 11 remains stationary in the axial direction. Under the action of the inclined surface, the second pushing surface 153 climbs up to the higher position along the first pushing surface 123. The support 11 moves outward in the lifting groove 17 until the support 11 moves radially outward to the first state A with an increased outer diameter.

[0081] To prevent the support member 11 from resetting under force during cleaning, a limiting mechanism 23 is provided between the column core 14 and the bracket 3 to prevent the column core 14 from moving axially, or a method such as Figure 22 A flat surface is provided on the outer side of the first pushing surface 123 or the inner side of the second pushing surface 153. In the first state A, the guide 12 and the mating part 15 support and form a limiting mechanism 23 in the flat surface position. When the roller 5 is cleaning the flat surface to be cleaned, the contact force between the roller 5 and the surface to be cleaned is perpendicular to the flat surface. The guide 12 and the mating part 15 form inner and outer support in the flat surface position, and cannot move along the inclined part of the first pushing surface 123 and the second pushing surface 153.

[0082] like Figure 23-25The guide 12 is configured as a first magnet 124, and the mating part 15 is configured as a second magnet 154 or a third magnet 154'. The second magnet 154 and the third magnet 154' form mating parts 15 according to different mating states. The first magnet 124 is fixedly mounted on the core 14, and the second magnet 154 and the third magnet 154' are fixedly mounted on the inner side of the support 11. The second magnet 154 and the third magnet 154' are located on the same plane and are installed at intervals. Taking the N pole of the first magnet 124 as close to the support 11 as an example, the second magnet 154 and the third magnet 154' face the first magnet 124 with their N pole and S pole respectively. The core 14 is still axially movable on the bracket 3, and one end of the support 11 is still... When the support member 11 is in the second state B, the first magnet 124 is located near the third magnet 154'. The magnetic poles of the first magnet 124 and the third magnet 154' are different and attract each other. The distance between the support member 11 and the core 14 is small. When the core 14 is pushed or pulled, the first magnet 124 and the third magnet 154' separate until the first magnet 124 is close to the second magnet 154. The magnetic poles of the first magnet 124 and the second magnet 154 are the same. The repulsive force generated by the magnetic repulsion pushes the support member 11 along the lifting groove 17 to a position away from the core 14 and the first magnet 124, so that the support member 11 expands outward and is maintained in the first state A. Because the direction of the repulsive force of the magnet is difficult to control, excessive force can easily be applied when pushing or pulling the core 14, causing the first magnet 124 to move past the second magnet 154. A limiting mechanism 23 can be set to restrict the movement of the core 14. When the core 14 moves to the preset end position of the limiting mechanism 23, the first magnet 124 stops exactly in the position directly opposite the second magnet 154. The user can better control the pushing and pulling force, and the movement generated by the like repulsion between the first magnet 124 and the second magnet 154 is more stable. When this structure is used, the lint roller 4' can be suspended and contact the surface to be cleaned for cleaning.

[0083] The above-mentioned connection method can also be set in the form of actively controlling the movement of the support member 11 relative to the column core 14. While retaining the aforementioned boss, guide groove, or linkage mechanism, adaptive adjustments are made to the connection structure between the column core 14 and the bracket 3, and between the support member 11 and the bracket 3, so that the column core 14 is axially fixed relative to the bracket 3, and the support member 11 is axially movable relative to the bracket 3. For example... Figure 26-27Taking the guide 12 as an insert block 121 and the mating part 15 as a groove 151 as an example, one end of the core 14 is mounted on the bracket 3, and the other end is away from the bracket 3 or kept at a distance from the bracket 3 so that the support 11 can be inserted and installed. The support 11 is installed on the outer periphery of the core 14 by connecting the guide 12 and the mating part 15. The support 11 is provided with an elastic element 24. The elastic force of the elastic element 24 keeps the support 11 in the second state B. Under the action of external force, the support 11 actively moves along the axial direction of the core 14 and moves radially outward with the cooperation of the guide 12 and the mating part 15 until it moves to the position where the guide 12 and the mating part 15 abut against the limit or the support 11 abuts against the limit of the bracket 3. The lint roll 4' is supported and tensioned by the roller 5.

[0084] like Figures 28-30 In this embodiment, the core 14 or the support 11 can also be used without being connected to the bracket 3. For example, one end of the core 14 extends outward, and the user directly holds the core 14 to control the lint roller 1'; or the core 14 has a perforation in the center, and the user inserts their finger or other cylindrical object into the perforation to use the lint roller 1'. When installing and removing the lint roller 4', the user controls the core 14 with one hand and controls the end of the support 11 with the other hand to create relative axial movement between the core 14 and the support 11, thereby changing the outer diameter of the roller 5.

[0085] In addition to the above methods, the support member 11 can also be moved by controlling the circumferential rotation of the column core 14, such as... Figures 28-29 The guide 12 is configured as a gear 125, and the mating part 15 is configured as a rack 155. The gear 125 is coaxially arranged with the core 14, and the rack 155 is fixed on the support 11. The racks 155 of different supports 11 mesh with different positions of the same gear 125, or mesh with different gears 125. The core 14 is controlled to rotate, which drives the gear 125 to rotate. The rotation of the gear 125 causes each rack 155 to drive the support 11 to move outward or inward, so as to switch between the second state B and the first state A.

[0086] like Figures 30-31 The guide 12 is configured as a sloping groove 126, the mating part 15 is configured as a pin 156, and the end of the core 14 is provided with a connecting plate 126'. The diameter of the connecting plate 126' is larger than the diameter of the core 14. The sloping groove 126 is located at the eccentric position of the connecting plate 126'. There is an angle between the sloping groove 126 and any diameter of the connecting plate 126'. The diameter of the pin 156 is adapted to the width of the sloping groove 126. When the core 14 is rotated, the sloping groove 126 begins to deflect. The side wall of the sloping groove 126 pushes the pin 156 to move. Under the limiting action of the lifting groove 17, the pin 156 drives the support 11 to move outward or inward to switch the use state.

[0087] like Figures 32-33 The guide 12 is configured with an external thread 127, and the mating part 15 is configured with an internal thread or a mating rod 157 that can be inserted into the external thread 127. The surface of the core 14 is provided with a conical surface, the external thread 127 is provided on the conical surface, and the internal thread is placed outside the external thread 127 or the mating rod 157 is installed in the groove of the external thread 127. The rotation of the core 14 is controlled to rotate the external thread 127. The lifting groove 17 prevents the support member 11 from moving axially. Under the action of the internal thread or the mating rod 157, the core 14 moves axially while rotating, and changes the distance between the end of the internal thread or the mating rod 157 and the bottom of the groove of the external thread 127. Under the action of external force, the support member 11 can move to the position of being close to the core 14 to the second state B. Similarly, when the core 14 is rotated in the opposite direction, the core 14 and the external thread 127 move in opposite directions. Under the support of the conical surface, the internal thread or the mating rod 157 gradually moves outward until the support member 11 tensions and supports the lint roll 4'. Preferably, in order to facilitate the automatic inward movement of the support member 11, an elastic element 24, such as a ring-shaped rubber band, can be fitted around the outer periphery of each support member 11. When the column core 14 moves, the elastic force of the rubber band drives the support member 11 to move inward so that the end of the internal thread or mating rod 157 fits against the conical surface for support.

[0088] like Figure 34 The guide 12 is configured as a cam 128, and the mating part 15 fits against the outer side of the cam 128. The rotating column core 14 changes the mating position between the cam 128 and the support 11. Because the different positions of the cam 128 are different from its center position, the support 11 can move radially inward or outward, thereby changing the outer diameter of the roller 5.

[0089] Preferably, the length of the core 14 is greater than the length of any support member 11, providing space for the movement of the support member 11. When the support member 11 is in the first state A, the end of the core 14 is exposed, allowing for the installation of limiting mechanisms 23 such as caps or pressure caps on the core 14 at this position to prevent the elastic member 24 from driving the support member 11 to reset. Simultaneously, guide members 12 can be spaced at both ends or even the middle of the core 14, with each guide member 12 moving synchronously relative to the support member 11, causing the support member 11 to move radially inward or outward under force. Alternatively, the core 14 can be configured as a short shaft located only at the end of the support member 11, further driving the overall radial movement of the support member 11 by driving one end of the support member 11 radially. Of course, the support member 11 can also be configured as follows: Figure 35One end of the support member 11 remains in the first state A with an increased outer diameter, while the other end is provided with a core 14. The core 14 and the support member 11 at that end cooperate to change the outer diameter of that end. In the first state A, the roller 5 remains parallel and in close contact with the lint roll 4' for support. In the second state B, the outer diameter of one end of the roller 5 remains unchanged, while the outer diameter of the other end decreases, making the roller 5 conical or frustum-shaped. The inclined outer surface of the roller 5 still allows for axial movement, installation, and removal of the lint roll 4'. To make the radial movement and internal support of the support member 11 more stable, such as... Figure 36 Two cores 14 can be provided, which are respectively installed on the two ends of the support member 11. The support member 11 can be moved radially as a whole by the two cores 14 supporting the two ends of the support member 11.

[0090] Preferably, the roller 5 is provided with an anti-slip element 25. The anti-slip element 25 increases the resistance between the lint roller 4' and the roller 5, preventing the lint roller 4' from moving axially or rotating circumferentially relative to the roller 5. The outer surface of the lint roller 4' is sticky. When the lint roller 4' comes into contact with the surface to be cleaned, the stickiness will create resistance to the rotation of the lint roller 4'. If the surface of the roller 5 or the inner side of the lint roller 4' is relatively smooth, the resistance created by the stickiness will cause relative rotation between the lint roller 4' and the roller 5, affecting the rotation and movement of the roller 5 and the cleaning effect of the lint roller 4' on the surface to be cleaned. When cleaning uneven surfaces such as clothing or pets on the body, the direction of the force applied by the hand and the direction of movement of the roller 5 and the lint roller 4' are related. If there is an angle between the roller 5 and the lint roller 4', or if they do not move in a direction perpendicular to their axis, axial slippage can easily occur between the lint roller 4' and the roller 5. This causes the end portion of the lint roller 4' to detach from the roller 5 and form wrinkles that surround the end side of the roller 5, affecting the subsequent rotation of the lint roller 4' and even affecting the automatic disassembly of the lint roller 4' under gravity. The anti-slip components 25, such as anti-slip pads, textures on the outer surface of the roller 5, or rubber bands, increase the frictional resistance between the roller 5 and the lint roller 4' to overcome the above defects.

[0091] The expansion mechanisms described above are all equipped with a core column 14. The core column 14 drives the support member 11 to move and provides support to the support member 11 in the first state A from the inside, so that the support members 11 are combined to form a roller 5 that is close to a cylinder. The movements of multiple support members 11 can be synchronized. In addition to this connection method, the roller 5 can also be set to other shapes.

[0092] In the above solution, the handle 2 and the lint roller 4' of the lint roller 1' can be installed on the same straight line or perpendicularly to the handle 2 and the lint roller 4'. One end of the lint roller 4' is blocked by the bracket 3 or the handle 2, and the other end is connected to the outside or has a movable end cap 26. When installed, the lint roller 4' is worn on the roller 5. When disassembled, the roller 5 shrinks in size, and the lint roller 4' automatically detaches from the roller 5 axially under gravity, or it automatically detaches from the roller 5 axially under gravity after the end cap 26 is opened. Compared with the traditional lint roller 1', the lint roller 4' in this embodiment does not require hand contact when disassembling, making the operation more hygienic. Moreover, only the lint roller 4' is disassembled and discarded, without affecting the installation structure of the lint roller 1', and will not increase the additional usage cost for consumers.

[0093] Preferably, in this embodiment, the lint roller 1' can be used not only with a lint roller 4' that only has an adhesive layer 6, but also with a traditional lint roller 4' that has a cardboard tube 7. The installation, cleaning, use, and disassembly of the two types of lint rollers 4' are largely the same.

[0094] like Figures 37-38 The roller 5 can also be adjusted in size by pneumatic or hydraulic means. Specifically, the roller 5 includes a core 14 and an air bladder 27. The core 14 is rotatably fixed on the bracket 3. The air bladder 27 is cylindrical and fixed on the core 14. The end of the air bladder 27 is provided with an air inlet valve 28 and an air outlet valve 29. The air inlet valve 28 is connected to a pressurizing mechanism to increase the air pressure inside the air bladder 27. In the second state B, the air pressure inside the air bladder 27 is low, causing the air bladder 27 to shrink or to collapse and deform inward under force. The lint roller 4' can be sleeved on the surface of the air bladder 27. The pressurizing mechanism inflates and pressurizes the air bladder 27, increasing the diameter of the air bladder 27 or increasing the strength of the surface of the air bladder 27 to tension and support the lint roller 4'. When disassembling, it is only necessary to release the air and reduce the pressure by using the air outlet valve 29. After the diameter of the air bladder 27 shrinks, the lint roller 4' can be easily removed.

[0095] Preferably, the airbag 27 is made of rubber with a certain strength, such as tire material, which can avoid the situation where the airbag 27 is too extensible and over-inflated, causing the lint roller 4' to burst. By limiting the range of diameter variation of the airbag 27, the pressurization time and force of the airbag 27 are more controllable. At the same time, after being pressurized to the preset air pressure value, the air inside the airbag 27 is mainly pressurized, and the volume increase of the airbag 27 is limited, which can improve the overall strength of the airbag 27 and provide reliable support for the use of the lint roller 4'.

[0096] Preferably, both the intake valve 28 and the exhaust valve 29 are configured as duckbill valves. During the intake pressurization process, the exhaust valve 29 will not automatically exhaust air. Furthermore, during the exhaust process when the exhaust valve 29 is open, or when the pressurization mechanism is disengaged from the intake valve 28, outside air will not enter the airbag 27.

[0097] In other embodiments, the cleaner 1 can also be configured as a mop, window wiper, duster, etc. When configured as a mop, the wiping material 4 is configured as a mop cloth, which is fitted onto a mop head with a roller 5 structure. The roller 5 structure is used to change the cross-sectional area of ​​the mop head to realize the installation and removal of the mop cloth. When the cleaner 1 is configured as a window wiper, duster, etc., the wiping material 4 is adapted to be configured as a rag, duster head, etc. The roller 5 structure on the cleaner 1 is used to change the cross-sectional area to facilitate the installation and removal of the wiping material 4.

[0098] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
