Description

Technical Field

[0001] This utility model belongs to the field of cleaning tools technology, specifically relating to a cleaning sheet and a cleaning kit. Background Technology

[0002] With the improvement of modern living standards, people's cleaning needs for home life have upgraded from basic "surface cleaning" to "refined quality cleaning". More and more users are beginning to pay attention to the health details of their home environment - whether it is dust accumulated in the grout lines of floor tiles, cobwebs in the corners of walls, or dust mites in the crevices of furniture, these have become the focus of cleaning.

[0003] The trend towards more compact and functionally diverse living spaces has led people to place higher demands on the "scenario adaptability" and "space utilization efficiency" of cleaning tools: they want tools that can flexibly handle the efficient cleaning of large areas of floors and walls, while also taking into account the precise handling of small areas such as narrow gaps and corners; they want both convenient and efficient cleaning processes, and also pay attention to the storage convenience and environmental economy of the tools themselves.

[0004] However, traditional handheld cleaning tools typically use a fixed-size design, requiring separate configurations for different cleaning scenarios (such as cleaning large areas of the floor or cleaning narrow crevices). This forces users to purchase multiple sets of cleaning products, increasing usage costs. Furthermore, they occupy significant storage space when not in use, resulting in resource waste. Currently, the limitations of handheld cleaning tools—limited functionality and insufficient adaptability to different scenarios—still fall short of the convenient living experience people seek. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a cleaning sheet and a cleaning kit.

[0006] The purpose of this invention is to develop and provide new cleaning products that are adaptable to multiple scenarios and economical, so as to help improve the quality of modern home life.

[0007] The first aspect of this utility model is to provide a cleaning sheet, including a substrate layer and a cover layer and a dust-removing fiber layer respectively disposed on both sides of the substrate layer; the substrate layer, cover layer and dust-removing fiber layer are pressed together, and the collection of pressed parts forms a pressing pattern; the pressing pattern reserves a retaining channel extending along the length direction of the cleaning sheet in the gap between the substrate layer and the cover layer, and the rear end of the retaining channel has an opening to form an insertion end for inserting a strip at the front end of the operating handle; the cleaning sheet has a full-size state and a half-size state with different lengths, respectively adapted to the full-size operating handle and the half-size operating handle, the front end of the full-size operating handle has a full-size strip, and the front end of the half-size operating handle has a half-size strip; in the half-size state, the half-size strip is inserted into the retaining channel, and the front area of ​​the cleaning sheet not occupied by the half-size strip is folded back to overlap with the rear area and held by a fixing structure, and the part of the retaining channel cut off by the fold line is used to insert and retain the half-size strip; in the full-size state, the cleaning sheet is kept in an unfolded shape, the retaining channel is not folded off but remains continuous in the length direction, and is used to insert and retain the full-size strip.

[0008] As a further optimization of the cleaning pad, the overall length of the cleaning pad is L0, and the length of the front region is L1, preferably 0.35≤L1 / L0≤0.6, more preferably 0.40≤L1 / L0≤0.55. In the full-size state, the length occupied by the full-size insert in the retaining channel of the front region is L2, preferably L2 / L1≥0.75, more preferably L2 / L1≥0.80.

[0009] As a further optimization of the cleaning sheet, the fixing structure includes at least one adhesive sheet disposed on the surface of the cover layer. The adhesive sheet is disposed on at least one side of the fold line, and the front area is folded back and then bonded to the rear area by the adhesive sheet.

[0010] As a further optimization of the cleaning pad, the fixing structure includes a hook and loop fastener assembly disposed on the surface of the cover layer. The hook and loop fastener assembly includes hook-faced patches and loop-faced patches symmetrically arranged along the fold line. After the front area is folded back, it is fixed by the interlocking of the hook-faced patches and the loop-faced patches.

[0011] As a further optimization of the cleaning pad, the fixing structure includes at least one hook at the base of the half-size insert and at least one hanging hole corresponding to the front end of the front area; after the front area is folded back, the hook and the hanging hole engage to achieve fixing.

[0012] As a further optimization of the cleaning sheet, the pressing pattern includes a central pressing line extending along the length of the cleaning sheet and an array of pressing points distributed on both sides of the central pressing line; the central pressing line intersects with the fibers of the dust removal fiber layer, causing the fibers to spread out to both sides along the central pressing line; the pressing point array contains multiple pressing points spaced apart, dividing the spread fibers into fiber bundles of different lengths; the pressing point arrays on both sides form two retaining channels with the central pressing line, and the retaining channels form a plug-in engagement with a pair of full-size inserts of the full-size operating handle in the full-size state, and a plug-in engagement with a pair of half-size inserts of the half-size operating handle in the half-size state.

[0013] As a further optimization of the cleaning pad, the pressing pattern also includes at least one anti-detachment limiting point located on the central pressing line; the longitudinal side of the full-size insert is provided with an anti-detachment protrusion that cooperates with the anti-detachment limiting point, and the longitudinal side of the half-size insert is also provided with an anti-detachment protrusion that cooperates with the anti-detachment limiting point; when the full-size insert or the half-size insert is inserted into the retaining channel, the interference cooperation between the anti-detachment protrusion and the anti-detachment limiting point forms an axial limit.

[0014] As a further optimization of the cleaning pad, a foldable extension is provided at the rear end of the cover layer. The foldable extension is folded back along the insertion direction to form a double-layer superimposed area. Within the double-layer superimposed area, a reinforcing structure composed of continuous embossed strips is formed by pressing patterns. The embossed strips are arranged along the opening edge of the retaining channel to reinforce the opening area.

[0015] As a further optimization of the cleaning sheet, the rear edge of the substrate layer extends beyond the rear edge of the cover layer, forming an open visible area between the two rear edges. The missing boundary of the cover layer in the open visible area forms a visual guide mark for the insertion end of the retention channel.

[0016] As a further optimization of the cleaning sheet, several cutting lines are cut on both sides of the substrate layer and the cover layer. The substrate layer and cover layer materials between adjacent cutting lines form cleaning strips, and the cleaning strips and the fiber bundles of the dust removal fiber layer constitute a three-dimensional cleaning system.

[0017] The second aspect of this utility model is to provide a cleaning kit, including multiple cleaning pads as described above, at least one full-size operating handle, and at least one half-size operating handle; the full-size operating handle and the half-size operating handle are respectively equipped with full-size inserts and half-size inserts adapted to the retaining channels of the cleaning pads, and the full-size operating handle and the half-size operating handle can be selectively assembled with the cleaning pads according to the needs of the cleaning scenario.

[0018] Beneficial effects

[0019] This utility model provides a cleaning pad that innovatively achieves free conversion between full-size and half-size states through a pressing design of a substrate layer, a cover layer, and a dust-removing fiber layer, while maintaining a channel structure. In the full-size state, the through-hole retaining channel can accommodate a full-size insert, allowing the cleaning pad to unfold into a large size suitable for cleaning large areas such as floors and walls, or for working in narrow crevices. When switching to the half-size state, the front area folds over and overlaps with the rear area, retaining only the channel portion that accommodates the half-size insert, forming a short, easy-to-grip structure to meet the fine cleaning needs of small areas such as corners and crevices. This "one-piece, two-use" design, through its folding structure and insert mechanism, significantly improves the cleaning pad's adaptability to different cleaning scenarios, avoiding the cumbersome need for separate dedicated cleaning tools for different scenarios. Simultaneously, the pressing process ensures a tight bond between the three layers, enhancing the cleaning pad's structural strength and durability.

[0020] Furthermore, by optimizing fiber distribution through embossing patterns, offering multiple fixing structure options, and designing a three-dimensional cleaning system, a multifunctional and highly compatible cleaning solution has been formed. The pressure point array and central pressure line work together to create a gradient cleaning structure in the fiber layer, balancing the adsorption of large particles with cleaning of crevices; multiple fixing mechanisms such as Velcro and adhesive sheets enhance the reliability of the folded state; the foldable extension and embossed strips strengthen the durability of the openings, extending the service life; the cleaning strips formed by the cut texture work synergistically with the fiber layer to improve the removal of stubborn stains. With the modular cleaning kit configuration, users can quickly switch between handle and cleaning pad combinations according to their needs, achieving full coverage cleaning from the floor to crevices, combining high efficiency, economy, and ease of use.

[0036] The present invention is further illustrated by the following embodiments, which are intended to more clearly illustrate the technical solution of the present invention, and should not be construed as a limitation.

[0037] like Figures 1 to 5 As shown, the cleaning sheet mainly consists of three parts: a substrate layer 1 in the middle, a cover layer 2 covering one side of the substrate layer 1, and a dust removal fiber layer 3 covering the other side of the substrate layer 1.

[0038] The substrate layer 1 and the cover layer 2 are preferably made of flexible, thin materials, such as non-woven fabric or fiber composite sheets with good toughness, to provide basic structural strength for the cleaning sheet and make it less prone to damage during use. The dust-removing fiber layer 3 is composed of a large number of bundled fibers, which can effectively adsorb dust, hair and other dirt, and is the main source of the cleaning function.

[0039] The substrate layer 1, cover layer 2, and dust removal fiber layer 3 are pressed together using pressing processes such as hot pressing and ultrasonic pressing. This pressing can be done in one step or in multiple steps, and the combined pressed parts form a pressing pattern 4. A retaining channel 5 extending along the length of the cleaning sheet is reserved between the substrate layer 1 and the cover layer 2 in the pressing pattern 4. The rear end of this retaining channel 5 has an opening, forming an insertion end for inserting the insert strip at the front end of the operating handle.

[0040] The cleaning pads come in various configurations, including a longer full-size configuration and a shorter half-size configuration, allowing selection based on the specific cleaning needs. Correspondingly, the full-size cleaning pads can be used with... Figure 6 The full-size operating handle shown is compatible with the half-size cleaning pad, which can be used with... Figure 7 The half-size operating handle shown is adapted for this purpose. The full-size operating handle has a handle 99 with a longer full-size insert 91 at the front end; the half-size operating handle also has a handle 99 with a shorter half-size insert 92 at the front end.

[0041] Figure 1 The image shows the cleaning sheet in its full-size state. In this state, the cleaning sheet remains unfolded, and channel 5 remains unbroken along its length, allowing the full-size insert 91 to be inserted and held, forming a shape as shown. Figure 8 The cleaning pad in this state is long and thin, making it suitable for scenarios requiring cleaning of large areas, such as floors and walls, as well as for cleaning narrow crevices, such as furniture crevices.

[0042] Figure 9 The image shows the cleaning pad in its half-size state. In this state, the half-size insert 92 can be inserted into the retaining channel 5. The front area 61 of the cleaning pad, not occupied by the half-size insert 92, folds backward to overlap with the rear area 62 and is held in place by a fixing structure, ensuring a stable folded state. During the folding process, the retaining channel 5 is cut off by the fold line 63, leaving only the channel portion within the rear area 62 for inserting and retaining the half-size insert 92. This state results in a shorter cleaning pad, making it more flexible to hold and easier to control precisely. It also features abundant cleaning fibers on both sides, making it suitable for fine cleaning of small areas such as corners and crevices.

[0043] As mentioned above, this structure, which allows a single cleaning pad to flexibly switch between full-size and half-size states, and by adapting to different sizes of operating handles, enables the cleaning pad to meet the needs of efficient cleaning of large areas as well as the scenarios of fine cleaning of small areas, significantly improving the scenario adaptability and usage efficiency of cleaning tools.

[0044] The overall length of the cleaning pad is L0, and the length of the front region 61 is L1. Preferably, the ratio of the front region 61 to the overall length satisfies 0.35 ≤ L1 / L0 ≤ 0.6, and more preferably, this ratio is further limited to 0.40 ≤ L1 / L0 ≤ 0.55. For example, in some embodiments, when the overall length L0 of the cleaning pad is 30cm, the length L1 of the front region 61 is preferably designed to be 10.5cm to 18cm, more preferably 12cm to 16.5cm. The L1 / L0 ratio balances the compactness of the folding structure with the adaptability of the operating handle, maintaining sufficient insert clamping length while reducing the size of the cleaning pad. Furthermore, in the full-size state, the length of the holding channel 5 in the front region 61 occupied by the full-size insert 91 is L2, and its ratio to L1 must satisfy L2 / L1 ≥ 0.75. For example, in some embodiments, when L1 is 15cm, L2 is at least 11.25cm. This proportion ensures that the full-size insert 91, once inserted, occupies most of the front area 61, maintaining the length of the channel 5, thus preventing the connection from becoming loose or falling off due to insufficient insertion depth.

[0045] When the cleaning pad is in its half-size state, a fixing structure is needed to maintain its stability in the folded state. For example... Figure 10 As shown, in some embodiments, the fixing structure uses adhesive sheets 81 to achieve folding and fixing. At least one adhesive sheet 81 is located on the surface of the cover layer 2, positioned on at least one side of the fold line 63. After the front region 61 is folded backward, it is bonded to the rear region 62 via the adhesive sheet 81. For example, two rectangular adhesive sheets 81 are arranged on the surface of the cover layer 2 at a distance of 3-5 mm from the fold line 63, with the length direction of the adhesive sheets 81 perpendicular to the fold line 63. When the cleaning sheet needs to be switched to a half-size state, the release film on the surface of the adhesive sheet 81 is removed, and the front region 61 is folded backward 180° along the fold line 63. At this time, the adhesive sheet 81 contacts the surface of the cover layer 2 of the rear region 62 and generates adhesive force, forming a stable double-layer folded structure. This structure achieves folding and fixing through simple pressure-sensitive adhesive, which is convenient to operate and low in cost.

[0046] like Figure 11As shown, in some other embodiments, the fixing structure includes a Velcro assembly disposed on the surface of the cover layer 2. The Velcro assembly includes hook-and-loop fasteners 83 and loop fasteners 84 symmetrically arranged along the fold line 63. After the front region 61 is folded backward, it is fixed by the interlocking of the hook-and-loop fasteners 83 and the loop fasteners 84. For example, two sets of Velcro assemblies are symmetrically arranged within a 20mm range on both sides of the fold line 63 on the surface of the cover layer 2: the hook-and-loop fasteners 83 are 100mm × 5mm in size and are fixed to the cover layer 2 of the front region 61; the loop fasteners 84 are 150mm × 5mm in size and are fixed to the cover layer 2 of the rear region 62. When a folding operation is performed, the hook-and-loop fasteners 83 and the loop fasteners 84 come into contact, and a reversible mechanical lock is formed by the interlocking of the hook and loop fibers. This reusable mechanical fixing method facilitates quick adjustment of the folded state and is particularly suitable for scenarios that require frequent switching of usage states. In addition, the difference in hook and hair area provides a certain tolerance for folding deviation; the Velcro assembly, with the nesting of hook and hair fibers, enhances the structural support of the folding part of the cleaning sheet, making the overall shape more rigid and improving the rigidity and stability during operation.

[0047] like Figure 12 As shown, in some other embodiments, the fixing structure includes at least one hook 85 located at the base of the half-size insert 92, and at least one hanging hole 86 correspondingly located at the front end of the front region 61; after the front region 61 is folded back, the hook 85 engages with the hanging hole 86 to achieve fixing. The hook 85 can be integrally injection molded at the base of the half-size insert 92, or it can be assembled at the base of the half-size insert 92 via a snap-fit ​​structure. The hanging hole 86 of the front region 61 can be formed by stamping. The mechanical engagement between the hook 85 and the hanging hole 86 also has high connection strength and durability.

[0048] like Figure 4 and Figure 5As shown, the pressing pattern 4 includes a central pressing line 41 extending along the length of the cleaning sheet and an array of pressing points 42 distributed on both sides of the central pressing line 41. The central pressing line 41 is a continuous linear pressing structure that runs through the length of the cleaning sheet and intersects with the fiber orientation of the dust-removing fiber layer 3. During the pressing process, the originally neatly arranged fiber bundles are dispersed to both sides along the central pressing line 41. This dispersion structure effectively increases the bulkiness and surface area of ​​the dust-removing fiber layer 3, allowing the fiber bundles to make more full contact with the cleaning surface and improving the adsorption capacity for dirt such as dust and hair. The pressing point array 42 includes multiple pressing points spaced apart. Each pressing point can be circular, polygonal, or irregular in shape, and can locally press an area, evenly distributed on both sides of the central pressing line 41. These pressing points further divide the dispersed fiber bundles into fiber units of different lengths. The fiber bundles near the central pressing line 41 are longer, forming a bulky main cleaning area; the fiber bundles near the edge of the cleaning sheet are shorter, forming a delicate edge cleaning area. This differentiated fiber distribution design allows the cleaning pads to achieve rapid dust removal over a large area through long fiber bundles, while also utilizing short fiber bundles for fine cleaning deep into crevices, creating a three-dimensional and efficient cleaning system.

[0049] In terms of structural layout, two parallel retaining channels 5 are formed between the pressure point arrays 42 on both sides and the central pressure line 41. These two retaining channels 5 extend along the length of the cleaning sheet, and their cross-sectional width is adapted to the insert size of the operating handle: In the full-size state, the two retaining channels 5 remain connected after the cleaning sheet is unfolded, and a pair of full-size inserts 91 at the front end of the full-size operating handle can be inserted simultaneously. The inserts fit tightly against the inner wall of the channel, forming a stable insertion fit; In the half-size state, after the front area 61 is folded, only the retaining channels 5 of the rear area 62 are retained. At this time, the two channels can be adapted to a pair of half-size inserts 92 of the half-size operating handle, ensuring that inserts of different specifications can be reliably fixed.

[0050] like Figures 6 to 8 and Figures 10 to 12As shown, the pressing pattern 4 also includes at least one anti-detachment limiting point 43 located on the central pressing line 41. The anti-detachment limiting point 43 can be set as a local dot-shaped pressing area. The longitudinal side of the full-size insert 91 is provided with an anti-detachment protrusion 93 that cooperates with the anti-detachment limiting point 43, and the longitudinal side of the half-size insert 92 is also provided with an anti-detachment protrusion 93 that cooperates with the anti-detachment limiting point 43. When the full-size insert 91 or the half-size insert 92 is inserted into the retaining channel 5, the interference fit between the anti-detachment protrusion 93 and the anti-detachment limiting point 43 forms an axial limit, which inhibits the cleaning pad from loosening during use. The anti-detachment protrusions 93 on the full-size insert 91 and the half-size insert 92 are set at positions that match the anti-detachment limiting point 43. The anti-detachment protrusions 93 on the full-size insert 91 and the half-size insert 92 can correspond to the same anti-detachment limiting point 43, or they can correspond to a different anti-detachment limiting point 43. The figure illustrates the case of corresponding to different anti-detachment limiting points 43.

[0051] In some embodiments, such as Figure 13 and Figure 14 As shown, the rear end of the cover layer 2 is provided with a foldable extension 21, which is folded back along the insertion direction to form a double-layer overlapping area, preferably folded towards the side of the substrate layer 1. Within the double-layer overlapping area, a reinforcing structure composed of continuous embossed strips 44 is formed by pressing patterns 4; the embossed strips 44 extend along the opening edge of the retaining channel 5 to reinforce the opening portion. By providing the foldable extension 21 and forming the aforementioned reinforcing structure, the durability of the opening portion of the retaining channel 5 can be significantly improved. During the insertion or removal of the insert from the operating handle, the opening portion maintains a stable shape due to reinforcement, ensuring that the insert can be smoothly inserted and firmly fixed within the retaining channel 5, while also being able to withstand multiple insertion and removal operations without easily deforming, tearing, or wearing. Furthermore, the combination of the double-layer overlapping area and the embossed strips 44 can also enhance the overall rigidity of the rear end of the cleaning pad to a certain extent, allowing the cleaning pad to maintain its original shape during use and maintain the overall cleaning effect.

[0052] In some embodiments, such as Figure 1 and Figure 5As shown, at the rear edge of the cleaning pad, the rear edge of the substrate layer 1 extends outward (i.e., in the direction of the opening of the retaining channel 5) compared to the rear edge of the cover layer 2, creating a staggered structure. The area between the two rear edges not completely covered by the cover layer 2 forms an open viewing area. Within this open viewing area, the edge of the cover layer 2 is not flush with the edge of the substrate layer 1, but forms a missing boundary on the substrate layer 1, creating a clear visual contrast. This provides intuitive visual guidance for inserting the operating handle insert. When the user needs to insert the insert into the retaining channel 5, the position of the insertion end can be clearly identified through the open viewing area. For example, in dimly lit or narrow cleaning scenarios, the user can quickly align the insertion end without repeatedly adjusting the angle, significantly improving the assembly efficiency of the cleaning pad and the operating handle. At the same time, the structure of the open viewing area does not add any additional components, achieving functionality only through edge misalignment and material exposure, reducing costs while ensuring the reliability and durability of the guidance markings. In addition, the exposed substrate layer 1 and the cover layer 2 can be set to have obvious differences in color and material to form more eye-catching guide signs and avoid operational inconvenience or damage caused by blindly searching for the insertion position.

[0053] like Figure 2 , Figure 3 and Figure 5 As shown, several cutting lines are uniformly processed along the edges of the substrate layer 1 and the cover layer 2 of the cleaning sheet through processes such as cutting and mechanical punching. These cutting lines extend along the width direction of the cleaning sheet and form a certain angle (e.g., perpendicular or inclined) with the length direction of the cleaning sheet. The substrate layer 1 and cover layer 2 materials retained between adjacent cutting lines naturally form strip-shaped or tooth-shaped structures that spread out to both sides, namely cleaning strips 7. The ends of the cleaning strips 7 are flush with or slightly offset from the ends of the fiber bundles of the dust-removing fiber layer 3. Together, they form a three-dimensional cleaning system in the areas on both sides of the cleaning sheet. The fiber bundles of the dust-removing fiber layer 3 adsorb light dirt such as dust and hair through their loose bundle structure, while the cleaning strips 7, with their rigid or semi-rigid strip-shaped protrusions, create mechanical friction and scraping action on stubborn stains and dust accumulation in crevices on cleaning surfaces such as floors and walls. For example, when the cleaning pad wipes the tile grout, the cleaning strip 7 can penetrate deep into the grout and remove dirt through physical contact, while the fiber bundles simultaneously absorb the removed dirt. The two work together to achieve a better cleaning effect and avoid secondary pollution.

[0054] This utility model further provides a cleaning kit, including multiple cleaning pads, at least one full-size operating handle, and at least one half-size operating handle. The full-size and half-size operating handles are respectively equipped with full-size inserts 91 and half-size inserts 92 that are adapted to the retaining channel 5 of the cleaning pads. The full-size and half-size operating handles can be selectively assembled with the cleaning pads according to the cleaning scenario requirements. When large-area cleaning is required, the user can remove the unfolded cleaning pad and fully insert the full-size insert 91 along the opening end of the retaining channel 5, achieving a stable connection using the through-channel structure. At this time, the dust-removing fiber layer 3 of the cleaning pad is fully unfolded, making large-area contact with the cleaning surface, suitable for floors, walls, and other scenarios. When fine cleaning of small areas such as corners and crevices is required, the front area 61 of the cleaning pad can be folded back and fixed to the rear area 62 through a fixing structure, forming a half-size state. The folding process naturally creates a fold line 63. A half-size insert 92 is then inserted into the retaining channel 5, which is cut off by the fold line 63. The short insert design makes the handle more flexible and allows for precise control of the cleaning position. This cleaning kit's modular design allows for adaptation and switching between multiple scenarios. Users can freely assemble the kit according to their actual cleaning tasks, avoiding the need to equip separate cleaning tools for different scenarios, reducing usage costs while increasing tool utilization. Furthermore, the multiple cleaning pads allow users to replace worn-out pads during cleaning, maintaining consistent cleaning results, making it particularly suitable for cleaning needs in various scenarios such as homes and offices.

[0055] The above embodiments are exemplary and are intended to illustrate the technical concept and features of this utility model, so that those skilled in the art can understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
