Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cleaning tools technology, specifically relating to a dust removal cleaning sheet and a duster. Background Technology
[0002] In both daily life and industrial cleaning, dust removal tools such as dust dusters are commonly used to remove light dirt such as dust and hair due to their convenience and efficiency. These tools, through the operation of the handle and cleaning pad, can clean areas such as furniture surfaces and wall crevices. They are widely used in homes, offices, hotels, and other settings, and are one of the important tools for maintaining environmental cleanliness.
[0003] As the component that directly contacts dirt, the cleaning pad of a duster is typically designed as a consumable, requiring replacement after a single use or a limited number of cleaning cycles. Due to its consumable nature, production costs must be strictly controlled, thus it is often made from low-cost, flexible materials such as non-woven fabric. While these materials meet basic cleaning functions and are easy to mass-produce, their structural strength is limited, making them unable to withstand excessive external forces, thus becoming a key factor restricting the product's user experience.
[0004] However, in actual use, the insertion and connection of the cleaning pads to the operating handle faces significant challenges: on the one hand, cleaning pads made of low-cost materials are prone to tearing or breakage at the insertion point due to concentrated force; on the other hand, user habits vary greatly, and some users may blindly apply force due to impatience, further increasing the risk of cleaning pad breakage. These problems not only lead to waste of consumables but also cause user complaints due to frequent replacements or inconvenient operation, becoming a major pain point affecting the product's market acceptance.
[0005] Improving the reliability of the connection between the cleaning pad and the operating handle while strictly controlling costs, and reducing the breakage rate due to improper operation, has become an urgent technical challenge. Existing technologies often face limitations in material performance when designing structural reinforcement for low-cost consumables, and simply relying on improvements in user operating habits cannot fundamentally solve the problem. Therefore, a solution that balances cost control and reliability is urgently needed to address the economic and durability requirements of cleaning pads. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a dust removal cleaning sheet and a dust removal duster.
[0007] The purpose of this invention is to provide a dust removal cleaning sheet and duster that can reduce the damage rate during the connection between the cleaning sheet and the operating handle, while also being compatible with low-cost material properties.
[0008] The first aspect of this utility model is to provide a dust removal cleaning sheet, including a substrate layer, a cover layer and a dust removal fiber layer respectively disposed on both sides of the substrate layer; the substrate layer, the cover layer and the dust removal fiber layer are pressed together, and the collection of the pressed parts forms a pressing pattern; the pressing pattern reserves a retaining channel extending along the length direction of the cleaning sheet between the substrate layer and the cover layer, and the rear end of the retaining channel has an opening to form an insertion interface for inserting an operating handle; at the rear end opening of the retaining channel, the substrate layer and the cover layer are staggered front and back, and the rear end edge of the substrate layer extends beyond the rear end edge of the cover layer; a strip-shaped different-colored identification strip is also provided on the cover layer along its rear end edge, the color of the different-colored identification strip is different from the color of the substrate layer, so that a visual identification boundary is formed at the junction of the substrate layer and the cover layer.
[0009] As a further optimization of the dust removal and cleaning sheet, the different colored marking strips are simultaneously pressed onto the cover layer when the substrate layer, cover layer, and dust removal fiber layer are pressed together.
[0010] As a further optimization of the dust removal and cleaning sheet, the substrate layer and the cover layer are configured with the same color to enhance the visual recognition of the contrasting color marking strips.
[0011] As a further optimization of the dust removal and cleaning sheet, the color difference between the substrate layer and the different colored marking strip meets the requirements of a hue difference value ≥30°, an absolute saturation difference value ≥20%, or an absolute brightness difference value ≥15% in the HSV color space.
[0012] As a further optimization of the dust removal and cleaning sheet, the pressing pattern also includes an indicator pressing point, which is shaped like an arrow and located at the rear opening of the retaining channel, pointing towards the retaining channel.
[0013] As a further optimization of the dust removal 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 of the dust removal fiber layer to spread out to both sides along the central pressing line; the pressing point array includes multiple pressing points arranged at intervals, pressing at least part of the spread fibers together into several fiber bundles; the pressing point arrays located on both sides of the central pressing line form two retaining channels with the central pressing line for inserting the operating handle.
[0014] The second aspect of this utility model is to provide a duster, including the aforementioned dust cleaning plate and an operating handle; the operating handle includes a grip and a pair of inserts connected to the front end of the grip, the inserts being able to be inserted into two retaining channels of the cleaning plate respectively; a different colored marking strip is used to indicate the position of the insert.
[0015] As a further optimization of the above-mentioned duster, the pressing pattern includes a first limiting pressing point and a second limiting pressing point; the first limiting pressing point is located at the front end of the retaining channel and in the area between the two retaining channels, and is used to form an abutting engagement with the Y-shaped forked part at the root of the insert of the operating handle; the second limiting pressing point is located at the end of the retaining channel, and is used to form an abutting engagement with the front end of the insert.
[0016] As a further optimization of the aforementioned duster, the size of the cleaning pad in its free state is configured such that, during the insertion of the insert into the retaining channel, the second limiting pressure point first forms an abutment with the front end of the insert, while at this time, the first limiting pressure point has not yet formed an abutment with the Y-shaped fork at the root of the insert on the operating handle and a buffer gap remains.
[0017] As a further optimization of the aforementioned duster, the buffer spacing is 3mm~10mm.
[0018] As a further optimization of the above-mentioned duster, the pressing pattern also includes at least one anti-detachment limiting point located on the central pressing line; the side of the insert is provided with an anti-detachment protrusion that cooperates with the anti-detachment limiting point; when the insert is inserted into the retaining channel, the anti-detachment protrusion and the anti-detachment limiting point form an interference to prevent the insert from detaching in the opposite direction.
[0019] Beneficial effects
[0020] This utility model's dust removal cleaning pad offers excellent convenience and reliability. The color difference between the contrasting label strip and the substrate layer, combined with the arrow-shaped guide structure indicating the pressure points, forms a dual visual guidance system. This allows users to quickly locate the insertion interface and direction when inserting the operating handle, avoiding tearing of the cleaning pad due to blind operation. It is especially suitable for low-cost scenarios involving disposable consumables. The synchronous pressing process integrates the contrasting label strip and the cover layer into a single molding process, reducing production steps while ensuring the bonding strength between the label strip and the main structure of the cleaning pad, thus balancing manufacturing efficiency and operational stability.
[0021] The accompanying duster achieves a stable connection between the operating handle and the cleaning pad through limiting pressure points and an anti-detachment structure. The phased limiting buffer mechanism—where the second limiting pressure point engages first, and the first limiting pressure point provides a buffer gap—utilizes the elastic deformation of the flexible material to absorb the impact force during insertion, significantly improving the cleaning pad's resistance to external forces and avoiding the interface damage problems caused by excessive force in traditional disposable cleaning pads. The interference cooperation between the anti-detachment limiting point and the anti-detachment protrusion on the insert effectively prevents the handle from accidentally detaching during operation, ensuring the continuity of cleaning work.

[0030] 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.
[0031] Dust removal and cleaning tablets, such as Figures 1 to 3 As shown, it includes a substrate layer 1, a cover layer 2 disposed on both sides of the substrate layer 1, and a dust removal fiber layer 3.
[0032] The substrate layer 1 and the cover layer 2 are preferably made of flexible thin-layer materials, such as non-woven fabric or fiber composite sheets with good toughness, to give the cleaning sheet basic structural strength and make it less prone to damage during use. The dust removal fiber layer 3 is composed of a large number of bundled fibers, which are used to adsorb dirt such as dust and hair to achieve the cleaning function.
[0033] The substrate layer 1, the cover layer 2, and the dust-removing fiber layer 3 are pressed together, for example, using pressing processes such as hot pressing or ultrasonic pressing. The pressing can be done in one step or in multiple steps. The assembled pressed parts form a pressing pattern 4. After pressing, the assembled pressed parts form the pressing pattern 4.
[0034] The pressing pattern 4 has a retaining channel 5 extending along the length of the cleaning sheet between the substrate layer 1 and the cover layer 2. The rear end of the retaining channel 5 has an opening to form an interface for inserting the operating handle. At the rear end opening of the retaining channel 5, the substrate layer 1 and the cover layer 2 are misaligned, and the rear end edge of the substrate layer 1 extends beyond the rear end edge of the cover layer 2. A strip-shaped color-blocking strip 7 is also provided on the cover layer 2 along its rear end edge. The color of the color-blocking strip 7 is different from the color of the substrate layer 1, so that a visual identification boundary is formed at the junction of the substrate layer 1 and the cover layer 2.
[0035] Since cleaning pads are consumables, used only once or discarded after a few uses, costs are limited. While the substrate layer 1 and cover layer 2 have some strength, their overall strength is limited. Placing a contrasting color marking strip 7 at the rear edge of the cover layer 2, with the rear edge of the substrate layer 1 extending beyond the rear edge of the cover layer 2, plays a crucial role in this scenario. Its distinct color, different from the substrate layer 1, creates a clear boundary identification mark. When inserting the operating handle, the user can visually determine the insertion point's location by the contrasting color marking strip 7, eliminating the need for blind trial and error. This allows for quick and accurate insertion of the operating handle into the rear opening of the retaining channel 5, preventing damage such as tearing of the cleaning pad due to improper operation. This structure effectively connects the cleaning pad to the operating handle, reduces additional wear and tear caused by improper operation, and balances cost control with an improved user experience.
[0036] The contrasting color identification strip 7 is arranged at the rear edge of the cover layer 2. In some preferred embodiments, the contrasting color identification strip 7 is simultaneously pressed onto the cover layer 2 when the substrate layer 1, cover layer 2, and dust removal fiber layer 3 are pressed together. This reduces the need for separate setting of the contrasting color identification strip 7, controls production costs, and improves production efficiency.
[0037] In different embodiments, the width of the different colored marking strip 7 and the pressed pattern can be adjusted according to actual production needs. Figure 2 and Figure 3 The illustration shows two different widths and embossed patterns of the contrasting color identification strips 7. The wider strip provides more prominent visual guidance, making it easier for users to accurately locate the connector in low light or during rapid operation; the narrower strip enhances overall aesthetics while maintaining basic identification functionality. The surface pattern of the contrasting color identification strips 7 can be stripes, grids, dots, etc. Dense, coarse embossed patterns enhance the bonding strength of the strips, while sparse, fine embossed patterns better maintain the flexibility of the cleaning pad.
[0038] In some preferred embodiments, the substrate layer 1 and the cover layer 2 are configured with the same color to enhance the visual distinctiveness of the contrasting color identification strip 7. For example, both the substrate layer 1 and the cover layer 2 are white, and the contrasting color identification strip 7 is blue; or both the substrate layer 1 and the cover layer 2 are light gray, and the contrasting color identification strip 7 is red; or both the substrate layer 1 and the cover layer 2 are beige, and the contrasting color identification strip 7 is green.
[0039] In some preferred embodiments, the color difference between the substrate layer 1 and the contrasting color label 7 satisfies a hue difference ≥30°, an absolute saturation difference ≥20%, or an absolute lightness difference ≥15% in the HSV color space. This color difference can be determined by measuring the material under standard D65 illumination conditions using a colorimeter. This quantitative standard for color difference facilitates the standardized selection of raw materials in actual production and ensures that the contrasting color label 7 forms a stable and significant visual contrast with the substrate layer 1 under standard lighting conditions. This allows users to quickly identify the insertion interface position visually, even under complex lighting conditions or in fast-paced operation scenarios, preventing misalignment that could damage the cleaning pad.
[0040] In some preferred embodiments, the pressing pattern 4 further includes an indicator pressing point 46, which is arrow-shaped and located at the rear opening of the retaining channel 5, pointing towards the retaining channel 5. The indicator pressing point 46, in conjunction with the contrasting color marking strip 7, forms dual visual guidance through the directional marking of the arrow shape and the boundary marking of the color difference. This allows the user to quickly locate the insertion interface area through color contrast and clearly identify the insertion direction with the arrow pointing, thereby further improving the convenience and accuracy of the operating handle insertion.
[0041] In some preferred embodiments, 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 intersects with the fibers of the dust-removing fiber layer 3, causing the fibers of the dust-removing fiber layer 3 to spread out to both sides along the central pressing line 41. The pressing point array 42 includes a plurality of pressing points arranged at intervals, pressing at least partially spread fibers together into several fiber bundles. The pressing point array 42 located on both sides of the central pressing line 41 forms two retaining channels 5 with the central pressing line 41, for inserting the operating handle. This arrangement guides the fibers to spread out through the central pressing line 41 to form a fluffy cleaning area. Combined with the pressing point array 42, it can both ensure the cleaning ability of the dust-removing fiber layer 3 and construct a reliable retaining channel 5 structure.
[0042] Figure 4 The image shows a duster, comprising the aforementioned dust-removing cleaning disc and an operating handle. The operating handle is as follows... Figure 5As shown, it includes a handle 99 and a pair of inserts 91 connected to the front end of the handle 99. The inserts 91 can be inserted into the two retaining channels 5 of the cleaning plate respectively; the different colored marking strips 7 are used to indicate the position of the inserts.
[0043] In some preferred embodiments, the pressing pattern 4 includes a first limiting pressing point 43 and a second limiting pressing point 44. The first limiting pressing point 43 is located at the front end of the retaining channel 5 and in the area between the two retaining channels 5, and is used to form an abutment engagement with the Y-shaped forked portion at the root of the insert 91 of the operating handle. The second limiting pressing point 44 is located at the end of the retaining channel 5 and is used to form an abutment engagement with the front end of the insert 91. By limiting the insertion depth of the operating handle by the first limiting pressing point 43 and the second limiting pressing point 44, it is possible to avoid exceeding the preset position or damaging the cleaning pad.
[0044] In some preferred embodiments, the size of the cleaning pad in its free state is configured such that during the insertion of the insert 91 into the retaining channel 5, the second limiting pressure point 44 first forms an abutting engagement with the front end of the insert 91, at which time the first limiting pressure point 43 has not yet formed an abutting engagement with the Y-shaped fork at the root of the insert 91 of the operating handle and a buffer gap is left.
[0045] The above structure, through precise configuration of the cleaning pad's free-state dimensions, forms a phased limiting insertion buffer mechanism. When the insert 91 of the operating handle is inserted, the second limiting pressure point 44 contacts the insert 91 before the first limiting pressure point 43. Utilizing the stretchable properties of the cleaning pad's own material, such as non-woven fabric, it allows for moderate extension during insertion, first forming... Figure 6 The state shown, and then gradually formed Figure 7 The structure, as shown, converts the instantaneous impact force during user insertion into elastic deformation buffering of the material. This structure fully utilizes the buffering performance of the limited-cost material, significantly improving the cleaning pad's ability to withstand external forces and preventing tearing at the entrance of channel 5 due to excessive insertion force. It is particularly suitable for disposable cleaning pad products with limited costs.
[0046] In some preferred embodiments, the size of the buffer spacing is 3mm to 10mm.
[0047] In some preferred embodiments, the pressing pattern 4 also includes at least one anti-detachment limiting point 45 located on the central pressing line 41; the side of the insert 91 is provided with an anti-detachment protrusion 93 that cooperates with the anti-detachment limiting point 45; when the insert 91 is inserted into the retaining channel 5, the anti-detachment protrusion 93 and the anti-detachment limiting point 45 form an interference to prevent the insert 91 from detaching in the opposite direction, thereby improving the structural stability of the duster during the user's cleaning operation.
[0048] 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.
