Figures 1-4 show the dust removing duster 1 according to the first embodiment of the present disclosure. Among them, Figure 1 shows a front view of the dusting duster 1; Figure 2 shows a partial perspective view of the dusting duster 1; FIG. 3 shows a front view of the dusting duster 1 with the handle 10 removed; and FIG. Schematic diagram of dot matrix 5.

As shown in Figures 1 and 2, the ultra-soft and high-fluffy dust-removing duster 1 includes a first substrate layer 3, a second substrate layer 4, and a matrix 5 compounded on the first substrate layer 3 and the second substrate. Layer 4 on the fiber layer 2. The product structure of the dust removing duster 1 is a fiber layer 2, a first base material layer 3, and a second base material layer 4 in order.

The fibers of the fiber layer 2 are used to clean dust, and the first substrate layer 3 and the second substrate layer 4 are used not only to attach the fiber layer 2, but also to receive the handle 10 of the dust duster 1 between the two substrate layers. . The pressed lattice 5 is used to fix the fiber layer 2, the first base material layer 3 and the second base material layer 4 together at the same time.

The first base material layer 3 is stacked on the second base material layer 4. The shape of the first base material layer 3 and the second base material layer 4 can be set to be rectangular; in other embodiments, the first base material layer 3 and the second base material layer 4 can also be set to be square, trapezoidal, oval, Or any other suitable shape. The size of the first base material layer 3 and the second base material layer 4 may be set to be different from each other, for example, the width of the first base material layer 3 in the direction perpendicular to the fiber extension direction A is greater than the width of the second base material layer 4, The length along the fiber extension direction A is approximately equal to the length of the second substrate layer 4; in other embodiments, the sizes of the first substrate layer 3 and the second substrate layer 4 can also be set to be approximately the same. The first base material layer 3 and the second base material layer 4 may be formed of any flexible flat material, such as non-woven fabric, plastic sheet, and the like.

The fiber layer 2 is stacked on the first substrate layer 3, and includes a closely arranged fiber array. The fibers in the fiber layer 2 extend substantially along the fiber extension direction A. The shape of the fiber layer 2 can be set to a rectangle; in other embodiments, the fiber layer 2 can also be set to a square, trapezoidal, oval, or any other suitable shape. The size of the fiber layer 2 can be set to be different from the first substrate layer 3 and the second substrate layer 4, for example, the width of the fiber layer 2 in the direction perpendicular to the fiber extension direction A is smaller than the width of the first substrate layer 3. However, it is greater than the width of the second substrate layer 4, and the length along the fiber extension direction A is approximately equal to the length of the first substrate layer 3 and the second substrate layer 4; in other embodiments, the size of the fiber layer 2 is also It may be set to be substantially the same as the first base material layer 3 or the second base material layer 4. The fibers in the fiber layer 2 can be formed of any flexible elongated material.

As described above, the press lattice 5 fixes the fiber layer 2, the first base material layer 3 and the second base material layer 4 together at the same time. The pressure dot matrix 5 is an array of multiple pressure points, and may include multiple rows and columns of pressure points. The pressing points of multiple rows and multiple columns are spaced apart from each other along the fiber extending direction A, and spaced apart from each other in a direction perpendicular to the fiber extending direction A. Each pressure point can be oval, oval, teardrop, rectangular, or any suitable shape. Each pressing point presses a part of the fibers of the fiber layer 2 to the first base material layer 3 and simultaneously presses the corresponding part of the first base material layer 3 to the second base material layer 4. Thereby, the pressing lattice 5 presses the fiber layer 2 to the first base material layer 3, and at the same time presses the corresponding part of the first base material layer 3 to the second base material layer 4. In some embodiments, the pressing of the pressing lattice 5 may adopt a process such as thermal pressing.

As shown in Figure 3-5, the pressure dot matrix 5 includes three rows of pressure points arranged in parallel, where the end of each pressure point on one row of pressure points is different from the end of the corresponding pressure point on the other two rows of pressure points. Both have overlap d. Except for the end points on both sides, the width of the overlapping portion d is 0.5 mm to 10 mm, preferably 0.5 mm to 2 mm. The pressure points in the middle row are located on the center line of the dust removal duster 1, and the other two rows of pressure points are staggered on both sides of the middle row of pressure points, thereby forming a pressure point matrix 5.

The pressure lattice 5 ensures that all the fibers in the fiber extension direction A are fixed on the substrate layer. In particular, the pressure lattice 5 ensures that all fibers in the fiber extension direction A have at least one pressure point to fix them on the first substrate layer 3 and the second substrate layer 4, and some fibers have two The pressure points fix it on the first substrate layer 3 and the second substrate layer 4.

Therefore, as shown in FIG. 5, the press lattice 5 divides the fibers into units of different lengths, thereby forming fiber bundles of different lengths. In particular, the pressure lattice 5 divides the fibers in the fiber extension direction A into fiber bundles a, b, and c of different lengths. The length of the fiber bundle a is less than half of the size of the dust removal duster 1 in the fiber extension direction A, the length of the fiber bundle c is close to half the size of the dust removal duster 1 in the fiber extension direction A, and the length of the fiber bundle b is greater than the dust removal duster 1 Half of the size in the fiber extension direction A.

Fiber bundles of different lengths will cause the fibers to form a staggered surface after being scattered, which increases the surface area of the fiber layer 2 and allows more fibers to participate in cleaning, which improves the efficiency of fiber use, thereby greatly improving the dust removal duster 1. Dust removal ability. The structure of the pressure lattice 5 not only makes the fiber bundles of different lengths staggered and distributed, but also has an ultra-long fiber bundle b. After the product is scattered, the fibers of the fiber bundle b extend in the reverse direction, so that the actual length of the product fiber is greater than the theoretical length (that is, the half of the size of the dusting duster 1 in the fiber extension direction A), which further improves the dusting duster 1. Plumpness and fiber utilization.

In some embodiments, the dust removing duster 1 may also be provided with two rows of auxiliary pressure points 9.

Returning to FIG. 1, the press lattice 5 not only divides the fibers into units of different lengths, but also forms a handle fixing portion 6 between the first base material layer 3 and the second base material layer 4 to fix the handle. Particularly, the pressing dot matrix 5 forms a double-insertion handle fixing part that matches the double-insertion handle 10 between the base material layers.

In some embodiments, several pairs of pressure points in the middle row of pressure points form a number of handle stop portions 7 that fit the double-plug handle 10, and a number of matched handle stops 7 are provided on the inner side of the double-plug handle 10 The handle of the disengaging part 7 is prevented from being disengaged 8 so as to prevent the handle 10 from falling off the dust removing duster 1. This structure ensures the convenience and reliability of the assembly of the dust removing duster 1 and the double-inserted handle 10.

In some embodiments, as shown in FIG. 6, both sides of the first base material layer 3 and the second base material layer 4 are divided into positive and negative trapezoidal wave units 11. Two trapezoidal wave units adjacent to one side are positive and negative trapezoids, which are respectively a trapezoidal wave unit with the wide surface inward and a trapezoidal wave unit with the wide surface outward. This structure enables trapezoidal wave units with different strengths on both sides of the substrate layer, enhances the dust removal effect of the product, and improves the aesthetics of the product at the same time.

The dust removing duster 1 according to the first embodiment of the present disclosure adopts the form of a pressure dot matrix to realize the product without pressure lines, so that the middle part of the product has no continuous partition, and the fiber is bonded to at least one surface of the substrate layer in the form of a pressure dot matrix. At the same time, the handle fixing part is formed. In the fiber extension direction A, the unique pressure lattice 5 ensures that all fibers 2 have at least one point to fix it on the substrate layer, and some fibers have two points to fix it on the substrate layer. Because there is no pressure line in the middle, there is no continuous partition in the middle part of the product, which makes the product soft, and the fiber can be divided into units of different lengths, thereby obtaining an ultra-soft and high-fluffy cleaning layer. In addition, the pressure dot matrix produces a unique fixed part of the fixed handle, and finally an ultra-soft and high-fluffy dust-removing duster is obtained.

According to the dust removing duster 1 of the first embodiment of the present disclosure, the fibers are divided into fiber bundles a, b, and c of different lengths in the extension direction A, so that the appearance of the product is fuller, the utilization rate of the fibers is greatly improved, and the dust removal ability is improved. And it is easier to disperse when the product is in use. The unique pressure dot matrix makes the product without continuous partition, so that the product is more plump and beautiful, and can greatly improve the softness of the product. During product manufacturing, the instantaneous pressing area is greatly reduced, effectively improving the pressing strength and improving production efficiency.

According to the first embodiment of the present disclosure, the dust removing duster 1 fixes the fibers in a dot matrix manner. Compared with traditional products that use intermediate pressure lines to fix the fibers, there is no continuous partition in the middle of the product, which makes the product very soft and greatly improves the product. The fullness, aesthetics, and fiber utilization are beneficial to the product's fiber dispersal and very fluffy; at the same time, the instantaneous pressing area is greatly reduced when the product is manufactured, which effectively improves the pressing strength and improves the production efficiency.

The pressure lattice 105 simultaneously fixes the fiber layer, the first substrate layer and the second substrate layer together. The pressure dot matrix 105 is an array of multiple pressure points, and may include multiple rows and columns of pressure points. The pressing points of multiple rows and multiple columns are spaced apart from each other along the fiber extending direction A, and spaced apart from each other in a direction perpendicular to the fiber extending direction A. Each pressure point can be oval, oval, teardrop, rectangular, or any suitable shape. Each pressing point presses a part of the fibers of the fiber layer to the first substrate and simultaneously presses the corresponding part of the first substrate to the second substrate. Thus, the pressing lattice 105 laminates the fibers to the first substrate, and simultaneously presses the corresponding portion of the first substrate to the second substrate. In some embodiments, the pressing of the pressing lattice 105 may adopt a process such as thermal pressing.

As shown in Figures 7 and 8, the pressure dot matrix 105 includes two rows of pressure points arranged in parallel.
