Description

[Technical Field]

[0001] The present application relates to the field of daily necessities, and specifically to a dust-removing adhesive roller and a dust-removing cleaner. [Background technology]

[0002]

[0003] A dust removal adhesive roller is a commonly used cleaning tool for cleaning dust, hair, etc. from surfaces of items such as clothes, sheets, carpets, floors, and furniture. Its conventional structure includes a roller core and multiple layers of dust removal adhesive paper wound around the outer surface of the roller core. During use, a user holds the roller handle and rolls it over the surface to be cleaned, using the adhesive properties of the dust removal adhesive paper to attract dust. After the outer surface of the outer layer of dust removal adhesive paper is covered with dust, the user can peel off the outer layer of dust removal adhesive paper to expose the inner layer of dust removal adhesive paper, which can then be used again. This simple operation makes it convenient to use.

[0003] However, when conventional dust removal adhesive rollers are used to clean smooth surfaces (e.g., glass, shiny furniture, floors, etc.), the dust removal adhesive paper often sticks to the surface being cleaned, preventing the dust removal adhesive roller from rolling freely. As a result, the dust removal adhesive paper falls off and sticks to the surface being cleaned, making it difficult to remove, causing considerable inconvenience to users.

[0027] The embodiments of the present application provide an adhesive roller for dust removal that can remove dust without adhering to the surface to be cleaned and affecting normal use.

[0028] As shown in Figure 1, the dust removal adhesive roller according to the embodiment of the present application includes a roller core 200 and a plurality of dust removal adhesive sheets 100 wound spirally around the roller core 200. Each dust removal adhesive sheet 100 is wound independently, and after the outer layer of dust removal adhesive sheet becomes covered with dust, the outer layer of dust removal adhesive sheet can be torn off to expose a new, clean inner layer of dust removal adhesive sheet, which is convenient to use and simple to operate.

[0029] FIG. 2 is a schematic diagram of a sheet of dust removal adhesive paper 100 in an unfolded state. As shown in FIG. 2, the dust removal adhesive paper 100 is approximately parallelogram-shaped. FIGS. 3 and 4 are cross-sectional views of the dust removal adhesive paper. As shown in FIGS. 3 and 4, the dust removal adhesive paper 100 includes a base layer 110 and an adhesive layer 120 provided on the base layer 110. The base layer 110 has opposing first and second surfaces, and the adhesive layer 120 is provided on the first surface. The adhesive layer 120 has adhesive properties and faces outward when each dust removal adhesive paper 100 is wound around the roller core 200, thereby contacting the surface to be cleaned and adhering dust and impurities. The second surface of the base layer 110 faces the roller core 200, has no adhesive properties, and is the release surface for two adjacent layers of dust removal adhesive paper. When the adhesive strength of the outer layer of dust-removing adhesive paper 100 is reduced due to being covered with dust, the outer layer of dust-removing adhesive paper can be easily torn off, exposing the clean dust-removing adhesive paper located in the inner layer.

[0030] When multiple sheets of dust removal adhesive paper 100 are wound one layer at a time, the second surface of the base layer 110 of the dust removal adhesive paper located on the outer layer can be stacked and come into contact with the adhesive layer 120 of the dust removal adhesive paper located on the inner layer, and because the adhesive layer 120 has adhesive strength, it can adhere to the second surface of the base layer 110, ensuring that the dust removal adhesive roller can be wound tightly and preventing it from coming undone.

[0031] 2, 3, and 4, the adhesive layer 120 includes a plurality of dust removal adhesive strips 121 and a plurality of spacer strips 122, which are arranged alternately. The dust removal adhesive strips 121 are made of adhesive and have adhesive properties, with the exposed surface serving as a dust removal adhesive surface for adhering dust. The spacer strips 122 have no adhesive properties or only a low adhesive property, thereby reducing the area of ​​the adhesive layer 120 directly attached to the surface to be cleaned, which is advantageous for detaching the dust removal adhesive paper 100 from the surface to be cleaned, and allowing the dust removal adhesive roller to roll freely on the surface to be cleaned, making it highly versatile and applicable to any surface that needs cleaning.

[0032] FIG. 3 is a cross-sectional view of a dust removal adhesive paper according to a first embodiment of the present application. As shown in FIG. 3, the adhesive layer 120 may be formed as a single layer, and the dust removal adhesive strips 121 are multiple rubber strips separated from each other by spacer strips 122. The surface of the dust removal adhesive strips 121 exposed between adjacent spacer strips 122 is the dust removal adhesive surface, which functions as an active surface for adsorbing dust and impurities. In the single-layer structure shown in FIG. 3, two different types of adhesive may be applied to the base layer 110 using an adhesive application head, thereby simultaneously applying the dust removal adhesive strips 121 and the spacer strips 122, thereby forming the adhesive layer 120 at one time. The dust removal adhesive strips 121 and the spacer strips 122 may be arranged in parallel strips or in a wavy line shape, as long as the dust removal adhesive strips 121 can be spaced apart from each other.

[0033] FIG. 4 is a cross-sectional view of a dust-removing adhesive paper according to a second embodiment of the present application. As shown in FIG. 4, the adhesive layer 120 may be formed into a two-layer structure. The dust-removing adhesive strips 121 are the first layer and may be formed as a planar, continuously distributed strip that is integrally connected to each other. The spacer strips 122 are the second layer and are formed on the outer surface of the dust-removing adhesive strips 121. The area of ​​the first layer of adhesive between adjacent spacer strips 122 forms the dust-removing adhesive surface. For example, to form the two-layer adhesive layer 120, the first layer of adhesive may be applied onto the base layer 110 using an adhesive applicator head, and then the spacer strips 122 may be applied onto the first layer of adhesive.

[0034] In the example shown in the drawings, the spacer strips 122 are parallel lines extending along the length of the dust removal adhesive paper 100 and spaced apart from each other across the width of the dust removal adhesive paper 100. By aligning the extension directions of the dust removal adhesive strips 121 and the spacer strips 122 with the length of the dust removal adhesive paper 100, the dust removal adhesive strips 121 and the spacer strips 122 can be laid along the length of the raw paper when manufacturing the raw paper for the dust removal adhesive paper 100, which is beneficial for the continuous and smooth operation of the adhesive application device. The application width and thickness of the dust removal adhesive strips 121 and the spacer strips 122 are uniform and consistent, resulting in a more refined and beautiful appearance. Furthermore, the continuous application process makes the manufacturing process more convenient and simple.

[0035] According to the embodiment of the present application, the material constituting the dust removal adhesive strip 121 may be an adhesive commonly used in the prior art, such as an acrylic adhesive, a rubber adhesive, or a polyester adhesive, with an initial adhesive strength of 5# to 10# steel ball, a peeling force of 0.1 to 0.2 N, and an unwinding force of 0.08 N to 0.2 N. The material constituting the spacer strip 122 may be a viscoelastic material, such as an acrylic viscoelastic material.

[0036] In the exemplary structure shown in Fig. 3, the thickness of the dust removal adhesive strip 121 may be 8 to 15 µm, and the spacer strip 122 may protrude outward from the dust removal adhesive strip 121 by 30 to 100 µm. Of course, in the structure shown in Fig. 3, the outer surface of the spacer strip 122 may be flush with the outer surface of the dust removal adhesive strip 121. The thickness of the base layer 110 may be 50 to 60 µm.

[0037] The width of the spacer strips 122 is not particularly limited and may be designed depending on the material and surface condition of the surface to be cleaned and the initial adhesive strength of the dust removal adhesive strips 121. For example, the spacer strips 122 may have a width of 1 mm to 3 mm and an interval of 3 mm to 5 mm.

[0038] In the dust removal adhesive roller according to the embodiment of the present application, the dust removal adhesive paper 100 is spirally wound around the roller core 200. Due to the continuous layer structure formed by the spiral winding, each layer of the dust removal adhesive paper 100 is physically independent. Therefore, when the outer layer of the dust removal adhesive paper is torn, the inner layer of the dust removal adhesive paper is not torn, ensuring the tightness of the inner layer of the dust removal adhesive paper and not affecting the subsequent dust removal adhesive operation. Furthermore, the spiral winding method allows the dust removal adhesive paper 100 to form a "spiral reinforcing rib"-like structure on the roller core 200, improving the rigidity and stability of the entire dust removal adhesive roller when subjected to rolling pressure. This prevents excessive deformation of the roller core 200 and loosening or collapse of the paper wrap, ensuring that the dust removal adhesive roller can roll freely without collapse, especially when cleaning with high pressure.

[0039] In order for the dust removal adhesive paper 100 to be spirally wound around the roller core 200 and completely cover the outer surface of the roller core 200, the dust removal adhesive paper 100 is a parallelogram as shown in FIG. 2, and two opposing corners of the parallelogram are acute angles. As shown in FIG. 2, the parallelogram has four sides: a first side 101 and a second side 102 that are opposite each other, and a third side 103 and a fourth side 104 that are opposite each other. As shown in FIG. 5, when the dust removal adhesive paper 100 is spirally wound around the roller core 200, the first side 101 and the second side 102 are aligned with both axial ends of the roller core 200, and the third side 103 and the fourth side 104 are spirally wound around the roller core 200.

[0040] According to the embodiment of the present application, the dust removal adhesive paper 100 can be wound more than once around the roller core 200 to allow for tighter winding. According to the embodiment of the present application, the width of the dust removal adhesive paper 100 is smaller than the axial height h of the roller core 200, and the length of one dust removal adhesive paper 100 is greater than the circumferential length of the roller core 200, so that each dust removal adhesive paper 100 can be wound approximately two to three times around the roller core 200, allowing for tighter winding and preventing the paper from becoming unwound.

[0041] When each dust removal adhesive paper 100 is wound obliquely around the roller core 200, the two adjacent oblique sides can be butted against each other without leaving any gaps, thereby preventing dust from contaminating the inner layer of dust removal adhesive paper through the gap between the two adjacent oblique sides during the dust removal adhesive operation of the outer layer of dust removal adhesive paper. According to an embodiment of the present application, to ensure that no gaps are left between the two adjacent oblique sides, the oblique side of the outer layer of dust removal adhesive paper is stacked on the oblique side of the inner layer of dust removal adhesive paper, and the two are stacked by a certain width, so that the boundary of the spirally wound outer layer of dust removal adhesive paper is They are stacked on top of each other without leaving any gaps, to avoid exposing the inner layer of dust-removing adhesive paper.

[0042] FIG. 5 is a schematic diagram of the outer layer of dust removal adhesive paper partially unfolded. If the currently outermost dust removal adhesive paper is the nth dust removal adhesive paper, then n-1 dust removal adhesive paper sheets are wound on the already wound paper roll, where n is an integer greater than or equal to 1. As shown in FIG. 5, the dashed line indicates the top edge of the nth dust removal adhesive paper sheet after it has been wound once, corresponding to the third side 103 of the parallelogram. The bottom edge of the next wrap (corresponding to the fourth side 104 of the parallelogram) is stacked on top of the top edge of the previous wrap, avoiding any gap between them and thereby preventing the n-1th dust removal adhesive paper sheet from being exposed. For example, the stack width a of two adjacent wraps of dust removal adhesive paper sheets may be 2 mm to 5 mm.

[0043] For example, when each dust removal adhesive paper 100 is wound around the roller core 200, the first side 101 of the parallelogram is aligned with the bottom end of the roller core 200, and the fourth side 104 of each dust removal adhesive paper 100 is stacked on top of the third side 103. After winding is complete, the second side 102 of the parallelogram is aligned with the top end of the roller core 200. This ensures that one dust removal adhesive paper 100 completely covers the outer surface of the roller core 200.

[0044] In the dust removal adhesive roller according to the present application, the dust removal adhesive paper is wound at an angle so that each layer is stacked one by one, thereby preventing the inner dust removal adhesive paper from being contaminated while the outer layer of dust removal adhesive paper is adhering to dust. As a result, after the outer dust removal adhesive paper is peeled off, a clean and new inner dust removal adhesive paper is exposed, which does not affect the effectiveness and quality of the subsequent dust removal adhesive operation.

[0045] In order for the dust-removing adhesive paper 100 to be rolled up so that the edges are stacked, the length L1 of the first side 101 of the parallelogram must be greater than the circumference s of the paper roll currently being rolled, and the amount by which L1 is greater than s is represented by the symbol b, and the value of b may be 2 mm-5 mm.

[0046] The outer diameter of the roller core is d0, its axial length is h, and the thickness of each dust removal adhesive paper 100, corresponding to the thickness of the region where the adhesive layer 120 is located, is t. As the number of wound dust removal adhesive papers 100 increases, the diameter of the paper roll gradually increases. If the outer diameter of the paper roll after winding n-1 dust removal adhesive papers 100 is denoted by d, then after winding n-1 dust removal adhesive papers 100, the outer diameter of the paper roll is d = d0 + 2(n-1)t, and the circumference of the paper roll is s = πd = π * (d0 + 2(n-1)t). To ensure that the oblique side of the outer layer of dust removal adhesive paper is stacked on the oblique side of the inner layer of dust removal adhesive paper, the length L1 of the first side 101 of the nth dust removal adhesive paper must be greater than s. As described above, the length of L1, which is greater than s, is represented by the parameter b, where L1=s+b=π*(d0+2(n-1)t)+b, where n is an integer equal to or greater than 1.

[0047] When each dust removal adhesive paper 100 is rolled, the acute angle where the first edge 101 and the third edge 103 join is the starting point 105 of the roll, and the acute angle where the second edge 102 and the fourth edge 104 join is the ending point of the roll. After each dust removal adhesive paper 100 is rolled, the starting point 105 is stacked inside by the outer layer of dust removal adhesive paper, but the ending point is exposed to the outside and can be used as the peeling end 106, i.e., the starting point for peeling the dust removal adhesive paper. After the dust removal adhesive paper 100 is covered in dust, the user can easily peel the dust removal adhesive paper 100 starting from the peeling end 106. Figure 6 is a schematic diagram of the peeling end of the outer layer of dust removal adhesive paper in a peeled state.

[0048] However, if adhesive is also provided on the outer surface of the peeling end 106, the peeling end 106 will have little difference in appearance from other areas, making it difficult for users to recognize the location of the peeling end 106 and making it difficult to find the peeling end 106. When a user grips the peeling end 106, the adhesive will likely stick to the user's hand, resulting in a poor user experience. Therefore, according to an embodiment of the present application, the adhesive layer 120 is not provided at least in the area of ​​the peeling end 106.

[0049] 2, 5, and 6, in an embodiment of the present application, the adhesive layer 120 is provided on a portion of the base layer 110, rather than covering the entire base layer 110. As a result, one side of the adhesive layer 120 is provided with an adhesive-free region 130, which is free of adhesive. The adhesive-free region 130 extends at least to the region where the peeling end 106 is located. The adhesive-free region 130 is free of adhesive and exposed from the base layer 110, and is significantly different in appearance from the adhesive region where the adhesive layer 120 is located. This allows the user to easily identify the location of the peeling end 106, and also prevents the user's hands from getting stuck with adhesive when tearing the dust removal adhesive paper 100, improving the user experience.

[0050] According to an embodiment of the present application, the adhesive-free region 130 may be provided along the fourth side 104 and may extend to the second side 102. The adhesive-free region 130 may extend along the entire fourth side 104 to simplify the manufacturing process of the raw paper roll of the dust removal adhesive paper 100. For example, as shown in FIG. 2, the adhesive layer 120 and the adhesive-free region 130 are arranged side by side, with the width of the adhesive layer 120 being W1 and the width of the adhesive-free region 130 being W2, where W0 = W1 + W2. For example, W2 may be 8 mm-10 mm.

[0051] According to the embodiment of the present application, an adhesive-free area 130 is provided on only one side of the dust removal adhesive paper 100, which not only ensures that the peeling end 106 does not stick to the hand, but also increases the area of ​​the adhesive layer 120 on one sheet of dust removal adhesive paper 100, thereby increasing the effective operating area of ​​one sheet of dust removal adhesive paper 100, and is also advantageous in that the dust removal adhesive paper 100 can be tightly rolled up and will not come undone.

[0052] In the embodiment of the present application, the adhesive-free area 130 is arranged along the fourth side 104 of the parallelogram, and when the dust-removing adhesive paper 100 is rolled up, the acute angle where the first side 101 and the third side 103 intersect is the starting end 105 of the roll, the acute angle where the second side 102 and the fourth side 104 intersect is the ending end of the roll, and the adhesive-free area is exactly at the end of the peeling end 106, making it easy to identify the position of the peeling end 106 when peeling it off, and also improving the user experience because it does not come into contact with the adhesive and does not stick to the hand.

[0053] Because no adhesive is provided in the adhesive-free region 130, the back surface of the outer layer of dust removal adhesive paper faces the adhesive-free region 130 of the inner layer of dust removal adhesive paper, and no adhesive force can be formed between the two, which affects the tightness of the paper roll winding. Therefore, when the adhesive-free regions 130 of two adjacent layers of dust removal adhesive paper are overlapped, they cannot adhere tightly at the overlapping position, making the dust removal adhesive paper prone to unwinding. Furthermore, because the overlapping region of the adhesive-free region 130 is thinner than the overlapping region of the adhesive layer 120, this leads to uneven thickness of the dust removal adhesive roller, making it more susceptible to wrinkling and deformation.

[0054] According to an embodiment of the present application, in order to prevent the dust removal adhesive paper roll from easily becoming unwound and to make the wound thickness of the dust removal adhesive roller as uniform as possible, as shown in FIG. 7, when the dust removal adhesive paper 100 is wound onto the roller core 200, the adhesive-free areas 130 of two adjacent dust removal adhesive paper 100 are completely misaligned, and the adhesive layer 120 area of ​​the outer layer of the dust removal adhesive paper covers the adhesive-free area 130 of the inner layer of the dust removal adhesive paper, thereby improving the tightness of the winding of the dust removal adhesive paper and the uniformity of the thickness of the dust removal adhesive roller.

[0055] To ensure that the adhesive-free regions 130 of two adjacent sheets of dust removal adhesive paper 100 are offset, the winding start ends 105 of the two adjacent sheets of dust removal adhesive paper 100 are offset by a certain distance in the circumferential direction of the roller core 200, which distance is at least greater than the width of the adhesive-free regions 130 in the circumferential direction of the currently wound paper roll, thereby preventing the adhesive-free regions 130 of the two adjacent sheets of dust removal adhesive paper 100 from overlapping, particularly the peeling end 106 regions of the two adjacent sheets of dust removal adhesive paper from overlapping with each other, and preventing the paper roll from becoming unwound due to insufficient adhesion at the peeling end 106. The width of the adhesive-free regions 130 in the circumferential direction of the paper roll is 8-10 mm, and the offset distance may be, for example, 15 mm or more.

[0056] As shown in Figure 8, when the winding start ends of two adjacent dust removal adhesive sheets are misaligned, the peeling ends 106 of the two adjacent dust removal adhesive sheets will also be misaligned. The peeling ends of the outer dust removal adhesive sheets can be overlapped with the adhesive regions of the inner dust removal adhesive sheets, allowing the peeling ends of the outer layers to be adhered by the adhesive layers of the inner layers, preventing the peeling ends from unfolding. Therefore, according to the embodiment of the present application, the peeling ends 106 of the two adjacent peeling layers of dust removal adhesive sheets, which do not have adhesive, are prevented from overlapping with each other, and the problem of the peeling ends 106 becoming loose due to the inability of the peeling end regions to adhere tightly is solved.

[0057] As the dust removal adhesive paper 100 is stacked and wound, the diameter of the paper roll gradually increases, and the outer area gradually increases, requiring adaptive adjustment of the shape and area of ​​the dust removal adhesive paper 100. In the prior art, in order to meet the shape and area adjustment needs of each dust removal adhesive paper 100 when manufacturing a dust removal adhesive roller, it is necessary to use raw paper stock of multiple different widths and wind them onto the roller core 200. However, the appearance differences between raw paper stock trays are usually small, making it easy for workers to make mistakes and misalign the raw paper stock trays during installation, which complicates the process and increases the error rate, affecting production efficiency and yield.

[0058] In the dust removal adhesive roller according to the embodiment of the present application, the width W0 of the multiple sheets of dust removal adhesive paper 100 is the same, that is, the distance between the third side 103 and the fourth side 104 of the parallelogram is the same. Therefore, when manufacturing the dust removal adhesive roller, raw paper of the same specification can be wound to obtain dust removal adhesive rollers of multiple sheets of dust removal adhesive paper 100 with different shapes and areas. There is no need to adopt or replace raw paper of different specifications, which simplifies the production process and improves production efficiency.

[0059] In the dust removal adhesive roller according to the embodiment of the present application, each dust removal adhesive paper 100 is a parallelogram, and the lengths of two adjacent sides of the parallelogram may not be equal. For example, the length of the opposing first side 101 and second side 102 is L1, and the length of the opposing third side 103 and fourth side 104 is L2, where L2 may be greater than L1. The width of the dust removal adhesive paper 100 is W0, that is, the distance between the third side and the fourth side is W0, which corresponds to the width of the raw paper.

[0060] The first side 101 and the second side 102 of each dust removal adhesive paper 100 are aligned exactly with both ends of the roller core 200, so the distance between the first side 101 and the second side 102 is equal to the axial length h of the roller core 200. For multiple sheets of dust removal adhesive paper 100, the distance h between the first side 101 and the second side 102 and the distance W0 between the third side 103 and the fourth side 104 are constant. In order to adaptively adjust the shape and size of the dust removal adhesive paper 100 in accordance with changes in the diameter of the paper roll being wound around the dust removal adhesive roller, it is necessary to adjust the size of the parallelogram, i.e., the side length L1 and the angle θ.

[0061] Hereinafter, the angle between the first side 101 and the third side 103 is set to θ, and in order to easily calculate the angle and side lengths L1 and L2 of the parallelogram, right-angled triangles are taken along W0 and h in the parallelogram shown in FIG. 9, and each size parameter of the n-th dust-removing adhesive paper 100 satisfies the following formula: JPEG0003253201000003.jpg32170t represents the thickness of one sheet of dust removal adhesive paper 100, b represents the length allowance of the first edge 101 of the dust removal adhesive paper 100 after it has been wound around the current paper roll one turn, d0 represents the outer diameter of the roller core 200, d represents the outer diameter of the paper roll when the nth sheet of dust removal adhesive paper is wound around it, and corresponds to the outer diameter of the paper roll obtained after n-1 sheets of dust removal adhesive paper 100 have been wound around it, h represents the axial height of the roller core, L1 represents the length of the short side of the parallelogram, L2 represents the length of the long side of the parallelogram, θ represents the acute angle of the parallelogram, W0 represents the width of the dust removal adhesive paper 100, and n is an integer greater than or equal to 1.

[0062] When d0, b, n, h, and W0 are known, equation (2) can be obtained based on equation (1), thereby determining the size of the short side L1 of the parallelogram, and the angle θ of the parallelogram can be determined based on equation (3).The winding angle of each raw paper on the roller core 200 can be determined based on the short side L1 and the angle θ, thereby adjusting the winding angle according to the thickness of the paper roll and controlling the winding device.

[0063] Based on the determined axial length h of the roller core 200 and equations (3) and (4), the size of the long side L2 of the parallelogram can further be determined.

[0064] Therefore, according to the embodiments of the present application, the side length and angle θ of each dust-removing adhesive paper 100 can be determined, so that the shape and size of each dust-removing adhesive paper 100 can be adapted to the size of the dust-removing adhesive paper roller without changing the raw paper specifications, thereby simplifying the production process.

[0065] According to the embodiment of the present application, when the size of the dust removal adhesive paper 100 is determined, the width W2 of the adhesive-free area 130 is preset as needed, so that the width of the adhesive-free area 130 of each dust removal adhesive paper 100 in the circumferential direction of the roller core 200 can be determined based on the size of the acute angle of the parallelogram, thereby further determining the minimum distance between the peeling ends 106 of two adjacent dust removal adhesive papers. If the circumferential distance between the adjacent two-layer peeling ends 106 is greater than the circumferential width of the adhesive-free area 130 of the outer layer of dust removal adhesive paper, the peeling ends 106 of the two adjacent dust removal adhesive papers can be prevented from overlapping, ensuring the tightness of the winding of the dust removal adhesive paper 100 and preventing the paper roll from collapsing. Since the backsides of the peeling ends 106 of each dust removal adhesive paper 100 are all adhered facing the adhesive area of ​​the inner layer dust removal adhesive paper, when the peeling end of the outer layer dust removal adhesive paper is torn, the inner layer dust removal adhesive paper 100 is not torn, and erroneous tearing is avoided.

[0066] Because the thickness of the dust removal adhesive paper 100 is small and the difference in the winding diameter between adjacent sheets of dust removal adhesive paper 100 is small, the change in size and shape of the parallelogram is also small, and the difference in the winding inclination angle is also small. According to another aspect of the present application, adjacent x sheets of dust removal adhesive paper 100 may have the same size and shape, i.e., x sheets of dust removal adhesive paper may adopt the same winding angle θ, thereby simplifying the operation of adjusting the winding angle for each dust removal adhesive paper, and thereby avoiding the problem of reduced efficiency in the manufacturing process caused by using raw paper of different specifications. For example, based on the above formulas (1), (2), (3), and (4), the sizes and winding angles of the 1st, x+1th, 2x+1st, 3x+1st, ... sheets of dust removal adhesive paper are determined, and the first x sheets of dust removal adhesive paper use the winding angle of the 1st sheet of dust removal adhesive paper, and the next x+1st to 2xth sheets of dust removal adhesive paper use the corresponding winding angle of the x+1th sheet of dust removal adhesive paper, and so on for the rest, where x is an integer greater than or equal to 2. For example, every five sheets of dust removal adhesive paper may have the same shape, size, and winding angle.

[0067] According to an embodiment of the present application, there is further provided a dust cleaner including the above-mentioned dust removal adhesive roller and a handle. The handle includes a handle portion and a holder connected to the handle portion. The holders are inserted into both ends of the roller core 200 of the above-mentioned dust removal adhesive roller, allowing the dust removal adhesive roller to freely roll on the surface to be cleaned and attract dust. The dust removal adhesive roller is detachably connected to the holder, allowing the dust removal adhesive roller to be replaced.

[0068] In the dust removal adhesive roller of the present application, the multi-layer dust removal adhesive paper 100 is wound at an angle around the roller core 200, one layer at a time, to ensure a tightly wound structure that prevents the paper from unraveling and contaminating the inner layers of dust removal adhesive paper. The adhesive layer 120 is provided with spacer strips 122 to allow the dust removal adhesive roller to roll freely on the surface to be cleaned, thereby enabling it to be applied to a variety of surfaces. Because each dust removal adhesive paper 100 has the same width, raw paper of the same specifications can be used, which avoids the need to use raw paper of different specifications during the production of dust removal adhesive rollers, simplifying the production process and achieving high yield and efficiency. The structure and control of the dust removal adhesive paper winding device can also be simplified.

[0069] Although the embodiments of the present application have been described in detail with reference to the drawings, the scope of protection of the present application is not limited to the above examples. Those skilled in the art may make modifications and variations based on these examples without departing from the spirit and principles of the present application, and these modifications and variations may also fall within the scope of protection of the present application.
