Description

Technical Field

[0001] This invention relates to the field of mops, specifically a center-cut mop and a fully recycled mop cloth. Background Technology

[0002] A center-cut mop is a common variation of mop in daily life. It has a slit in the center of the mop to allow dirt and debris to move into the slit, making it easier to collect dirt and debris while mopping.

[0003] The mop cloths used in existing center-cut mops are mostly made of chemical synthetic fibers, such as polyester, nylon, and polypropylene. These fibers have good physical and chemical properties and can withstand long-term friction without damage.

[0004] Existing center-cut mops mostly use a single-sided tray, which may lead to excessive wear on one side after prolonged use. Furthermore, the existing mop cloth itself is difficult to degrade, the production process consumes a lot of energy, and it puts a great burden on the environment. The finished products made from the environmentally friendly fibers currently used have low strength and chemical resistance. Therefore, this paper proposes a center-cut mop and a fully recycled mop cloth to address the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, such as the fact that the trays of existing center-cut mops are mostly used on one side, which may lead to excessive wear on one side after prolonged use, and that existing mop cloths are difficult to degrade, consume a lot of energy during production, and put a great burden on the environment, as well as the low strength and chemical resistance of finished products made from the currently used environmentally friendly fibers, this invention proposes a center-cut mop and a fully recycled mop cloth.

The slot is opened at the position of the support plate facing the connecting block, and the storage cavity is opened on both sides of the connecting block. The connecting spring is located inside the storage cavity, with the side of the connecting spring near the insert block fixedly connected to the insert block, and the side of the connecting spring away from the insert block fixedly connected to the inner wall of the storage cavity. One side of the insert block is fitted inside the storage cavity, and the side of the insert block away from the storage cavity is inserted into the slot. The engaging assembly is located between the inner wall of the slot and the insert block. The connecting rod is fixedly connected to the rear side of the top of the insert block near the connecting spring. The push plate is fixedly connected to the connecting rod. The anti-slip pad is glued to the side of the push plate away from the connecting rod. The sliding assembly is located at the end of the push plate away from the connecting rod.

[0007] Preferably, four sets of mounting seats are symmetrically arranged on both sides of the top of the support plate via magnets. Each of the four sets of mounting seats has a mounting slot on the side away from each other. Each of the four sets of mounting slots is rotatably connected to a mounting shaft. Each mounting shaft is fixedly connected to a connecting rod on the outside. A side protection plate is fixedly connected to the side of the connecting rod away from the mounting shaft. A bottom protection plate is fixedly connected to the bottom end of the side protection plate. Each bottom protection plate is fixedly connected to a connecting block.

[0008] Preferably, two connecting rotating holes are symmetrically provided on the side protection plate, and a connecting rotating block is rotatably connected inside the connecting rotating holes.

[0009] Preferably, a connecting shaft is fixedly installed on the inner wall on both sides of the connecting rotating hole, and a connecting torsion spring is sleeved on the outer side of the connecting shaft. One end of the connecting torsion spring is fixedly connected to the connecting shaft, and the other end of the connecting torsion spring is fixedly connected to the inner wall of the connecting block.

[0010] Preferably, a limiting groove is formed on the inner wall of the mounting groove, and a mounting shaft is rotatably connected inside the limiting groove. A reset torsion spring is provided inside the mounting groove, one end of which is fixedly connected to the mounting shaft, and the other end of which is fixedly connected to the inner wall of the mounting groove.

[0011] Preferably, the engaging assembly includes a locking block and a locking groove. The locking block is glued to both ends of the inner wall of the slot and is made of rubber. The locking groove is opened at both ends of the locking block and engages with the locking block.

[0012] Preferably, the sliding assembly includes a slider and a groove. The slider is fixedly connected to the end of the push plate away from the connecting rod, and the slider is slidably connected inside the groove, which is located on the rear side of the connecting block.

[0013] The present invention also provides a fully recycled floor mop, comprising a center-cut floor mop as described in any of the preceding paragraphs. The floor mop is disposed on the outer side of the support plate. The floor mop includes an outer layer, an inner layer, and an edging. The inner layer is disposed on the inner side of the outer layer. The outer and inner layers are surrounded by an edging. The outer layer is made of spunlace fabric and is square in shape. The spunlace fabric is made of recycled polyester fiber. The raw materials of the recycled polyester fiber include 0.53dtex recycled polyester fiber and 1.56dtex recycled polyester fiber, and the ratio of the 0.53dtex recycled polyester fiber to the 1.56dtex recycled polyester fiber is 1:9. The inner layer is made of needle-punched fabric prepared from 100% recycled polyester and its shape is adapted to the outer layer. The edging is a plain-weave dyed fabric prepared from 100% recycled polyester spunlace fabric.

[0014] The advantages of this invention are:

[0015] 1. This invention achieves the function of using both sides of the support plate through the structural design of the connection structure. When one side of the support plate is worn excessively, the support plate can be flipped over for use. This solves the problem that the existing middle-cut mop trays are mostly single-sided and may become worn excessively on one side after long-term use, thus improving the overall service life of the mop.

[0016] 2. This invention, through the materials used in the mop, achieves the dual goals of meeting the requirements for strength, abrasion resistance, and resilience, while simultaneously reducing energy consumption during production, saving energy and reducing carbon emissions, recycling raw materials, and lowering environmental impact. It solves the problems of existing mops being difficult to degrade, consuming large amounts of energy during production, causing significant environmental pressure, and having low strength and chemical resistance in finished products made from currently used environmentally friendly fibers. The outer layer is made of spunlace fabric with a printed fully recycled polyester EF pattern, and because of the... The addition of a hydrophilic agent during production allows the outer fabric to absorb moisture, while the inner fabric, with a much higher absorbency, effectively locks in water. The uneven surface texture increases the mop's friction and dirt-holding capacity. Printed patterns can be added to enhance the mop's aesthetics, distinctiveness, and uniqueness. The inner fabric is made of recycled polyester needle-punched fabric, which is environmentally friendly and reduces carbon emissions, while also boasting high absorbency. The difference in absorbency between the inner and outer fabrics allows the mop to actively absorb and retain water. The edging uses 55g / m²... 2The 100% recycled polyester spunlace fabric is plain-weave dyed, which has high strength, increases the strength and service life of the finished mop, and is not easy to loosen. At the same time, the dyeing color increases the aesthetics of the mop. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figure 1-12 As shown, the present invention provides a center-cut mop and a fully recycled mop cloth. The center-cut mop includes a handle 1, a telescopic rod 2, a connecting block 3 and a support plate 4. The bottom end of the handle 1 is fixedly connected to the top end of the telescopic rod 2. The connecting block 3 is rotatably connected to the bottom end of the telescopic rod 2. The bottom end of the connecting block 3 is provided with the support plate 4. A connecting mechanism is provided between the connecting block 3 and the support plate 4.

[0034] Furthermore, four sets of mounting seats 6 are symmetrically arranged on both sides of the top of the support plate 4 via magnets. Each of the four sets of mounting seats 6 has a mounting groove 9 on the side away from each other. Each of the four sets of mounting grooves 9 is rotatably connected to a mounting shaft 10. Each mounting shaft 10 is fixedly connected to a connecting rod 11 on the outside. A side protection plate 12 is fixedly connected to the side of the connecting rod 11 away from the mounting shaft 10. A bottom protection plate 15 is fixedly connected to the bottom end of the side protection plate 12. Each bottom protection plate 15 is fixedly connected to a connecting rotating block 14.

[0035] Furthermore, two connecting rotating holes 13 are symmetrically opened on the side protection plate 12, and a connecting rotating block 14 is rotatably connected inside the connecting rotating hole 13.

[0036] Furthermore, a connecting shaft 7 is fixedly installed on the inner wall on both sides of the connecting rotating hole 13. A connecting torsion spring 8 is sleeved on the outer side of the connecting shaft 7. One end of the connecting torsion spring 8 is fixedly connected to the connecting shaft 7, and the other end of the connecting torsion spring 8 is fixedly connected to the inner wall of the connecting rotating block 14.

[0037] Furthermore, a limiting groove 16 is formed on the inner wall of the mounting groove 9, and a mounting shaft 10 is rotatably connected inside the limiting groove 16. A reset torsion spring 18 is provided inside the mounting groove 9. One end of the reset torsion spring 18 is fixedly connected to the mounting shaft 10, and the other end of the reset torsion spring 18 is fixedly connected to the inner wall of the mounting groove 9.

[0038] During operation, the side protection plate 12 and bottom protection plate 15 effectively protect the mop cloth structure, preventing damage during placement and use, extending the overall lifespan of the regenerated mop, and improving its practicality. The connecting rotating hole 13 facilitates the rotation of the connecting rotating block 14, and the connecting torsion spring 8 drives the connecting rotating block 14 to rotate, thereby causing the bottom protection plate 15 to press tightly against the mop cloth 5. The limiting rotating groove 16 and the limiting rotating block 17 interact to ensure the installation stability of the mounting shaft 10.

[0039] The connecting mechanism includes a storage cavity 301, a connecting spring 302, an insert block 303, a slot 304, a locking assembly, a connecting rod 307, a push plate 308, an anti-slip pad 309, and a sliding assembly. The slot 304 is located on the support plate 4 facing the connecting block 3. The storage cavity 301 is located inside both sides of the connecting block 3. The connecting spring 302 is located inside the storage cavity 301, and the side of the connecting spring 302 near the insert block 303 is fixedly connected to the insert block 303. The side of the connecting spring 302 away from the insert block 303 is fixedly connected to the inner wall of the storage cavity 301. One side of the insert block 303 is fitted inside the storage cavity 301. The side of the insert block 303 away from the storage cavity 301 is inserted into the slot 304. The engaging assembly is located between the inner wall of the slot 304 and the insert block 303. The connecting rod 307 is fixedly connected to the rear side of the top end of the insert block 303 near the connecting spring 302. The push plate 308 is fixedly connected to the connecting rod 307. The anti-slip pad 309 is glued to the side of the push plate 308 away from the connecting rod 307. The sliding assembly is located at the end of the push plate 308 away from the connecting rod 307.

[0040] During operation, when the support plate 4 needs to be flipped, the two sets of push plates 308 are first pushed away from the support plate 4. Under the action of the pushing force, the push plates 308 drive the insert blocks 303 to move synchronously through the connecting rod 307. One side of the insert block 303 compresses the connecting spring 302, causing the connecting spring 302 to undergo elastic deformation. The other side of the insert block 303 disengages from the inside of the slot 304, thereby disengaging the connection between the support plate 4 and the connecting block 3. Then, the support plate 4 is flipped over, and the slot 304 on the support plate 4 is aligned with the connecting block 3. After releasing the push plates 308, the insert blocks 303 can be reinserted into the inside of the slot 304 under the action of the restoring force of the connecting spring 302, thus connecting the support plate 4 and the connecting block 3.

[0041] Furthermore, the engaging assembly includes a locking block 305 and a locking groove 306. The locking block 305 is glued to both ends of the inner wall of the slot 304 and is made of rubber. The locking groove 306 is formed at both ends of the insert block 303 and engages with the locking block 305. During operation, when the insert block 303 is inserted into the slot 304, the two ends of the insert block 303 compress the locking block 305, causing the locking block 305 to undergo elastic deformation. When the insert block 303 is fully inserted into the slot 304, the compressive force of the insert block 303 on the locking block 305 disappears. At this time, the locking block 305 returns to its original shape under its own restoring force and engages with the locking groove 306, thus providing auxiliary fixation for the connection between the support plate 4 and the connecting block 3.

[0042] Furthermore, the sliding assembly includes a slider 310 and a groove 311. The slider 310 is fixedly connected to the end of the push plate 308 away from the connecting rod 307, and the slider 310 is slidably connected inside the groove 311, which is located on the rear side of the connecting block 3. During operation, when the push plate 308 moves, the slider 310, which is fixedly connected to the push plate 308, moves synchronously inside the groove 311. The synchronous movement of the slider 310 within the groove 311 enhances the stability of the push plate 308 during movement.

[0043] The present invention discloses a fully recycled floor mop, comprising a center-cut floor mop, wherein a floor mop 5 is disposed on the outer side of the support plate 4, the floor mop 5 comprising an outer layer 501, an inner layer 502, and an edging 503, the inner layer 502 being disposed on the inner side of the outer layer 501, and the edging 503 being disposed around the outer layer 501 and the inner layer 502, the outer layer 501 being made of spunlace fabric and having a square shape, the spunlace fabric being made of recycled polyester fiber, the raw materials of the recycled polyester fiber including 0.53dtex recycled polyester fiber and 1.56dtex recycled polyester fiber, the ratio of the 0.53dtex recycled polyester fiber to the 1.56dtex recycled polyester fiber being 1:9, the inner layer 502 being made of needle-punched fabric prepared from 100% recycled polyester, the shape being adapted to the outer layer fabric, and the edging 503 being a plain-weave dyed fabric prepared from 100% recycled polyester spunlace fabric.

[0044] During the process, first align and stack the inner layer fabric 502 needle-punched fabric and the outer layer fabric 501 spunlace fabric. Then, sew the four sides with binding 503. The width of the binding 503 after sewing is about 6mm-8mm. Then, fold it in half along the width direction, and sew it again along the width direction 6mm-10mm away from the folded edges at both ends. This seam is called the fold seam, and its length is about 119mm-121mm. The fold seam is located on the outside of the binding 503. Only sew the outer layer fabric 501 and the inner layer fabric 502. Excluding the 503 binding, the unfolded edge along the length direction is sewn with a stitch of approximately 39mm-41mm length near the two folded edges. This stitch is called the finishing stitch. One end of the finishing stitch intersects perpendicularly with one end of the folded stitch, ultimately forming a pocket-shaped structure. A slit is cut in the middle of the unfolded edge, with a slit length of approximately 48mm-52mm. The resulting floor mop is approximately 124mm-128mm wide and 490mm-500mm long.

[0045] The outer layer fabric 501 incorporates 0.53 dtex recycled polyester fiber because finer fibers have a larger specific surface area, improving adsorption and dyeability. The larger fiber-to-fiber contact area and higher friction during drafting result in higher fiber straightness, thus increasing fabric strength. Finer fibers also improve fabric softness. However, for spunlace equipment, finer fibers are prone to breakage during opening and carding, producing numerous short fibers. At high speeds, these fibers can form knots, negatively impacting the finished fabric's appearance and quality, reducing overall production efficiency, and potentially damaging machinery. Therefore, after multiple sampling tests, 0.53 dtex recycled polyester fiber and 1.56 dtex recycled polyester fiber were selected as the optimal raw material. When the ratio of dtex recycled polyester fiber is controlled at 1:9, it not only improves the softness, strength, and dyeing effect of the fabric to a certain extent, but also minimizes the impact on the spunlace machine equipment, making it almost negligible. It should be emphasized that the surface layer of 100% recycled polyester has very high longitudinal and transverse strength, which makes the mop cloth resistant to deformation, abrasion, toughness, and elasticity. In addition, the outer surface adopts an EF texture, which is uneven, which can increase the surface friction and the surface dirt-holding capacity. At the same time, different symbolic patterns can be printed on the surface spunlace, which can not only increase the aesthetics, but also make the product representative and unique. Table 1 shows the various performance parameters obtained from the 501 test of the outer layer fabric. Table 1 can corroborate the above-mentioned excellent performance of the outer layer fabric.

[0046] Table 1. Performance parameters of the outer layer fabric 501 obtained from testing.

[0047]

[0048] The inner layer 502 is made of needle-punched fabric and has the same shape as the outer layer 501. It is mainly an absorbent layer. Because the inner layer 502 is more absorbent than the outer layer 501, the water in the outer layer 501 will be actively absorbed into the inner layer 502. The outer layer 501 is made of fully recycled polyester. Even if a hydrophilic agent is added, the hydrophilic layer will absorb water, but polyester itself does not absorb water. Therefore, the mop cloth 5 absorbs water easily and drains water slowly throughout the process, locking in wastewater and cleaning more thoroughly and cleanly.

[0049] The 503 edge binding material is made of fully recycled polyester spunlace fabric. It does not absorb water and can better lock in the moisture inside the mop. It has high strength, making the entire structure less prone to loosening, more reliable, and with a longer service life. It can also reduce stains on the mop structure 5 during use. Table 2 shows the various performance parameters obtained from the testing of the 503 edge binding. Table 2 can corroborate the above-mentioned excellent performance of the edge binding.

[0052]

[0053] Working principle: When the support plate 4 needs to be flipped, the two sets of push plates 308 are first pushed away from the support plate 4. Under the action of the pushing force, the push plates 308 drive the insert blocks 303 to move synchronously through the connecting rod 307. One side of the insert block 303 compresses the connecting spring 302, causing the connecting spring 302 to undergo elastic deformation. The other side of the insert block 303 comes out from the inside of the slot 304, thereby disengaging the connection between the support plate 4 and the connecting block 3. Then, the support plate 4 is flipped over, and the slot 304 on the support plate 4 is aligned with the connecting block 3. After releasing the push plates 308, the insert blocks 303 can be reinserted into the inside of the slot 304 under the action of the restoring force of the connecting spring 302, thus connecting the support plate 4 and the connecting block 3.

[0054] When the push plate 308 moves, the slider 310, which is fixedly connected to the push plate 308, moves synchronously inside the slide groove 311. The synchronous movement of the slider 310 in the slide groove 311 makes the push plate 308 more stable during movement.

[0055] When the insert block 303 is inserted into the slot 304, the two ends of the insert block 303 press against the locking block 305, causing the locking block 305 to undergo elastic deformation. When the insert block 303 is fully inserted into the slot 304, the pressing force of the insert block 303 on the locking block 305 disappears. At this time, the locking block 305 returns to its original shape under its own restoring force and engages with the slot 306, which plays an auxiliary role in fixing the connection between the support plate 4 and the connecting block 3.
