Description

Technical Field

[0001] This utility model belongs to the field of cleaning tool technology, and specifically relates to a novel folding flat mop. Background Technology

[0002] Currently, existing flat mops connect the mop plate and handle via a hinge during mopping. This allows the mop plate to rotate within two perpendicular planes, but not freely within a given space. This limits its ability to adjust its position in confined spaces. Furthermore, during washing, to remove excess water, the mop plate is often folded parallel to the handle, using a squeegee at the bottom of the handle to scrape away water. This squeegee method results in low water absorption, causing the mop to dry quickly and requiring repeated squeegeeing. It also has a certain failure rate and can trap debris from the mop plate on the squeegee, requiring manual cleaning, which is tedious. Utility Model Content

[0003] To address the above problems, this utility model provides a novel foldable flat mop.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] Furthermore, the folding mechanism includes a flexible cable and a swing rod at its bottom. The cable is located inside the main rod, and its upper end is connected to the inner wall of the main rod. The lower end of the cable passes through the flexible hose and the middle of the fixed plate and is rotatably connected to one end of the swing rod. There are two swing rods, and the two swing rods are rotatably connected to the bottom surface of the folding plates on both sides. The bottom surface of the folding plate near the fixed plate has a groove for accommodating the swing rod. The lower part of the main rod is provided with a push-pull mechanism for driving the cable to move up and down to realize the unfolding and folding of the slide.

[0008] Furthermore, the push-pull mechanism includes an inner sleeve, a lever, and a first spring. The lever is Z-shaped. The first spring is horizontally positioned, with one end connected to the inner wall of the inner sleeve and the other end connected to the middle of the lever. The lower end of the lever is rotatably connected to the inner wall of the inner sleeve. The upper end of the lever extends through the inner sleeve and the side wall of the main rod and extends to the outside of the main rod. The upper end of the pull cable is connected to the support rod. Both ends of the support rod are connected to the inner sleeve and positioned below the lever. The side wall of the main rod is provided with a sliding groove for the lever to slide up and down. The lower end of the outer sleeve has a limiting ring inside for engaging with the upper end of the lever. The inner wall of the limiting ring has an annular groove, with the upper end of the annular groove being larger than the lower end.

[0009] The bottom of the outer sleeve is provided with an outer sleeve tube, the upper end of which is embedded in the inner hole of the outer sleeve and slides with the outer sleeve. The main rod is located inside the outer sleeve tube, and the upper end of the lever can cooperate with the bosses at both ends of the inner hole of the limiting ring during the pushing and pulling of the main rod.

[0010] Furthermore, the outer wall of the main rod is provided with a plurality of annular grooves along its length, and the upper end of the inner hole of the outer sleeve is provided with a positioning pin. The positioning pin is connected to the inner wall of the outer sleeve by a second spring; the end of the positioning pin is a spherical crown shape that matches the groove.

[0011] Furthermore, guide plates are provided on both sides of the central hose of the fixed plate, and limiting blocks are provided on the side of the two folding plates near the edge. The bottom surface of the limiting block is fixedly connected to the upper surface of one side of the folding plate, and the end of the limiting block extends to the top of the folding plate on the opposite side, so as to press against the folding plate on the opposite side when the slide is unfolded.

[0012] Furthermore, the dewatering structure includes two rollers, which are symmetrically arranged on both sides of the outer sleeve and the slide plate.

Detailed Implementation

[0030] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, this utility model provides a novel folding flat mop, including a mop handle and a folding mop plate. The bottom surface of the mop plate is provided with a detachable mop cloth (not shown in the figure). The mop handle includes a main rod 1 and an outer sleeve 2. The lower end of the main rod 1 is connected to the middle of the mop plate 4 through a hose 3. The lower part of the main rod 1 is provided with a folding mechanism for driving the mop plate 4 to fold or unfold. The outer sleeve 2 is disposed outside the main rod 1 and can slide up and down relative to the main rod 1. The lower outer side of the outer sleeve 2 is provided with a wringing structure for squeezing out excess water from the bottom mop cloth. The mop plate 4 includes a long strip-shaped fixed plate 41 and folding plates 42 on both sides. The connecting end of the folding plate 42 is rotatably connected to the fixed plate 41. The middle part of the fixed plate 41 is connected to the hose 3. The bottom surface of the folding plate 42 is provided with the mop cloth. This solution uses a folding mechanism to fold or unfold the mop, and the hose at the bottom of the main rod can swing in any direction, making it suitable for cleaning small spaces. The sliding outer sleeve drives the wringing structure to repeatedly squeeze the folded mop, squeezing out excess water from the mop cloth. At the same time, the detachable mop cloth makes it convenient to replace it after cleaning.

[0032] In specific embodiments of this utility model, such as Figure 4As shown, the folding mechanism includes a flexible cable 5 and a swing rod 6 at its bottom. The cable 5 is located inside the main rod 1, and its upper end is connected to the inner wall of the main rod 1. The lower end of the cable 5 passes through the flexible hose 3 and the middle of the fixing plate 41 and is rotatably connected to one end of the swing rod 6. There are two swing rods 6, which are rotatably connected to the bottom surfaces of the two side folding plates 42 respectively. The bottom surface of the folding plate 42 near the fixing plate 41 has a groove 40 for accommodating the swing rods 6. The lower part of the main rod 1 is provided with a push-pull mechanism to drive the cable 5 to move up and down to realize the unfolding and folding of the drag plate 4. The cable is made of flexible hose, which makes it easy to change the bending direction with the hose during mopping. This structure allows the cable to move in the opposite direction to the main rod as it moves up and down under the action of the push-pull mechanism. When the cable moves upward, it can drive the two swing arms to rotate to a horizontal state, so that the two folding plates can be flattened into a flat plate state. Conversely, when the cable moves downward, it can drive the two swing arms to reduce the angle between them, so that the free ends of the two folding plates can be folded downward, easily realizing the folding and unfolding of the slide.

[0033] Further optimize the above solution, such as Figure 6 , 8As shown, the push-pull mechanism includes an inner sleeve 20, a lever 7, and a first spring 8. The lever 7 is Z-shaped. The first spring 8 is horizontally arranged, with one end connected to the inner wall of the inner sleeve 20 and the other end connected to the middle of the lever 7. The lower end of the lever 7 is rotatably connected to the inner wall of the inner sleeve 20. The upper end of the lever 7 extends through the inner sleeve 20 and the side wall of the main rod 1 and extends to the outside of the main rod 1. The upper end of the cable 5 is connected to the support rod 19. The two ends of the support rod 19 are connected to the inner sleeve 20 and are located below the lever 7. The side wall of the main rod 1 is provided with a sliding groove 17 for the lever 7 to slide up and down, and the length of the sliding groove 17 matches the displacement of the cable 5 during the folding of the slide plate 4. The lower end of the outer sleeve 2 has a limiting ring 18 for cooperating with the upper end of the lever 7. The inner wall of the limiting ring 18 has an annular groove, and the upper end of the annular groove is larger than the lower end. In specific manufacturing, the inner sleeve 20 slides with the inner wall of the main rod 1, the lower end of the lever 7 is rotatably connected to the connecting rod, and both ends of the connecting rod and the support rod 19 are fixed to the inner wall of the inner sleeve 20; a rectangular notch for the lever 7 to move is pre-machined on the upper part of the side wall of the inner sleeve 20. Meanwhile, the bottom of the outer sleeve 2 is provided with an outer sleeve 9, the upper end of which is embedded in the inner hole of the outer sleeve 2 and slides with it. The main rod 1 is located inside the outer sleeve 9, and the raised part at the upper end of the lever 7 can engage with the bosses at both ends of the inner hole of the limiting ring 18 during the pushing and pulling of the main rod 1. When the mop 4 needs to be folded, the outer sleeve 2 is pushed downwards to move the outer sleeve 9 to abut against the mop 4. The outer sleeve 9, placed outside the hose 3, protects the hose 3. When the mop 4 needs to be unfolded, the outer sleeve 2 is pulled upwards to move the outer sleeve upwards, exposing the lower end of the hose 3 for easy bending during mopping. The above structure enables the folding and unfolding of the mop. The specific operation process is as follows:

[0034] Pushing the outer sleeve 2 downwards, the raised portion at the upper end of the lever 7 is positioned within the annular groove of the limiting ring 17. The outer sleeve 5 drives the lever 7 and the cable 5 to move downwards. The cable 5 drives the two swing arms 6 to rotate, which in turn drives the two folding plates 42 to fold. When the lower bent portion of the lever 7 retracts into the slide groove 17, the raised portion at the upper end of the lever 7 retracts inwards to ensure that the raised portion passes smoothly through the upper opening of the annular groove of the limiting ring. At this time, the outer sleeve 2 can drive the roller 13 of the squeezing structure to continue moving downwards, using the elastic element of the squeezing structure to achieve the squeezing action. In this process, pushing the outer sleeve 2 downwards first drives the folding plate 42 to fold, and then drives the roller 13 to move downwards to achieve squeezing, with the preceding and following actions being continuous. After the water is squeezed out, the outer sleeve 2 moves upward, and the lower end of the annular groove of the limiting ring 18 can abut against the raised part of the lever 7. The outer sleeve 2 continues to move upward, which can drive the lever 7 upward. Subsequently, the lower bent part of the lever 7 enters the slide groove 17. Under the action of the first spring 8, the raised part at the upper end of the lever 7 continues to move towards the bottom of the annular groove of the limiting ring 17. The protrusions at both ends of the annular groove of the limiting ring 17 play a limiting role on the lever 7. As the lever 7 moves upward with the outer sleeve 2, it drives the cable 5 to move upward, thereby turning the two folding plates 42 to a horizontal state, realizing the unfolding of the slide plate 4.

[0035] In specific embodiments of this utility model, such as Figure 7 As shown, the outer wall of the main rod 1 has multiple annular grooves 10 along its length. The upper inner hole of the outer sleeve 2 has a positioning pin 11, which is connected to the inner wall of the outer sleeve 2 by a second spring 12. The end of the positioning pin 11 is a spherical crown that matches the groove 10. When the outer sleeve moves upward to the groove position, the positioning pin pops out and enters the groove under the action of the second spring, thus fixing the outer sleeve and the main rod relatively. When it is necessary to fold the slide plate, the outer sleeve can be pushed downward to make the positioning pin overcome the elastic force of the second spring and disengage from the groove. Continuing to pull the main rod upward will move the lever downward to the lower end of the slide groove, thereby pulling the lower end of the main rod 1 to move in the opposite direction and driving the folding plates 42 on both sides to start folding.

[0036] Further optimize the above solution, such as Figure 1 , 5 As shown, guide plates 43 are provided on both sides of the central flexible hose of the fixed plate 41, and limiting blocks 44 are provided on the side of the two folded plates 42 near the edge. The bottom surface of the limiting block 44 is fixedly connected to the upper surface of one side of the folded plate 42, and the end of the limiting block 44 extends to the top of the opposite side folded plate 42, which is used to press against the opposite side folded plate 42 when the drag plate 4 is unfolded. The guide plates can protect the root of the flexible hose and prevent the connection between the flexible hose and the fixed plate from being broken due to excessive force. At the same time, the limiting blocks on both sides can prevent the two folded plates from rotating further after they are turned to a horizontal position, so that the drag plate remains horizontal and convenient for mopping.

[0037] In specific embodiments of this utility model, such as Figure 1 , 2 As shown, the dewatering structure includes two rollers 13, which are symmetrically arranged on both sides of the outer sleeve 2 and the slip plate 4. The two ends of each roller 13 are connected to the outer sleeve 2 via elastic elements 14. The rollers 13 can roll up and down along the outer surface of the slip plate 4, and the elastic elements 14 drive the rollers 13 to press against the slip plate 4. Specifically, the elastic element 14 is a U-shaped elastic metal rod. The closed end of the elastic metal rod faces upward, and its upper part is connected to the outer sleeve 2 via a connector 15. The two open ends of the elastic metal rod are rotatably engaged with the two ends of the rollers 13. The U-shaped elastic metal rod can be made of elastic spring steel bent into shape. The up-and-down sliding of the outer sleeve drives the rollers on both sides to roll up and down along the outer surface of the folded plate. During the rolling process, the rollers use the elastic force of the elastic elements to squeeze the two folded plates, thereby squeezing out excess water carried by the mop cloth.

[0038] To further optimize the above structure, a shoulder 21 is provided on the lower outer surface of the outer sleeve to limit the movement of the roller 13. Simultaneously, downward-sloping guide surfaces are provided on the upper edges of both sides of the guide plate 43. The shoulder limits the movement of the roller, preventing it from sliding downwards along the outer sleeve during mopping. When wringing is required, the outer sleeve is pushed downwards to fold the two side folding plates. When the roller moves to the shoulder at the lower end of the outer sleeve, further downward pushing of the outer sleeve overcomes the obstruction of the shoulder, and the roller continues to slide downwards along both sides of the guide plate to the outer surface of the folding plate 42, continuing the wringing action.

[0039] In practical applications, the folding plate 42 is bonded and fixed to the mop cloth using Velcro 16. Further optimization of the above structure is possible, such as... Figure 2 As shown, the folding plate 42 has several water outlet holes 23, and the Velcro 16 is attached to the bottom surface and / or the top surface of the folding plate 42. Alternatively, a base plate 45 can be provided at the bottom of the folding plate 42, and the Velcro 16 is attached to the bottom surface of the base plate 45 and / or the top surface of the folding plate 42. When wringing out water, the water outlet holes 23 on the folding plate facilitate quick drainage; simultaneously, the Velcro 16 is attached to the top surface, and after the mop cloth is attached to the bottom Velcro 16, its edges can be folded upwards and fixed to the top Velcro 16, further ensuring the mop cloth is securely fixed.

[0040] The mop cloth can be made of chenille, cotton, or other materials. Chenille is preferred due to its good water absorption. When using cotton or other materials, the towel can be attached to the Velcro on the bottom of the base plate. When using a chenille towel, the towel has an upward fold around its perimeter for easy attachment to the mop plate. It is secured using the Velcro 16 on both sides of the top surface of the folding plate and is also limited by the limiting plates 22 at both ends of the folding plate to prevent the towel from shifting during mopping and wringing.

[0041] In specific manufacturing, the flexible hose is made of a hose with embedded steel wire, the roller 13 is made of nylon, and the fixing plate 41, folding plate 42, guide plate 43, limiting block 44, and base plate 45 are all made of high-strength non-metallic materials. The base plate 45 can be made of nylon. The roller utilizes the high strength, wear resistance, corrosion resistance, and lightweight characteristics of nylon, making it suitable for applications involving frequent roller rolling and use in aquatic environments.

[0042] In summary, this invention boasts advantages such as compact structure, convenient folding and wringing, and free rotation. The flexible hose allows the main pole to swing in any direction and angle during mopping, facilitating cleaning in confined spaces. By pushing and pulling the main pole up and down, and with the limit lever, the swing arm can be driven to rotate via a cable, easily opening and closing the mop. The mop cloth is secured with Velcro for easy replacement, and the outer tube drives a roller to roll up and down along the folded mop surface, squeezing out excess water from the mop cloth under the action of an elastic element, achieving the wringing action without hand contact. This invention offers more convenient and faster operation; the freely swinging main pole adapts to spaces of different sizes; and the folded mop not only makes wringing easier but also saves storage space.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
