Description
Technical Field
[0001] This utility model belongs to the field of cleaning tool technology, and in particular relates to a wringer mop. Background Technology
[0002] Chinese patent CN219422741U discloses a "Shrinkable and Squeezable Foam Mop," which includes a mop handle, a foldable mop head, and a drive component. The foldable mop head has a foam wiping agent that folds along with it. The drive component, mounted on the mop handle, can move up and down. When the drive component moves downwards, it causes the foam wiping agent to swing with the foldable mop head, remaining in a folded state. The downward movement of the drive component also acts on a push plate, causing the upper end of the folded foam wiping agent to shrink from top to bottom, thus squeezing out water. However, when the mop handle rotates relative to the foldable mop head until they are close to each other along their length, the drive component interferes with the foldable mop head. At this point, it is impossible to achieve a nearly parallel state between the mop handle and the foldable mop head, limiting its usability. Utility Model Content
[0003] To overcome the shortcomings of the existing technology, this utility model provides a wringer mop, which can adjust the wringer sleeve to a first position through a positioning structure, so as to ensure that the mop handle and the folding mop head can rotate freely to near parallel, making it more flexible to use.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a wringer mop, including a mop handle, a folding mop head rotatably connected to the mop handle, a wiping material installed on the folding mop head, and a wringer sleeve movably installed on the mop handle. The wringer sleeve is used to push the folding mop head to rotate and approach to squeeze the wiping material. A positioning structure is provided between the wringer sleeve and the mop handle, which is used to position the wringer sleeve in a first position of the mop handle. In the first position, when the mop handle rotates to approach the folding mop head, the wringer sleeve avoids the folding mop head.
[0005] This invention uses a positioning structure to position the wringer sleeve at the first position of the mop handle. At this position, the wringer sleeve avoids the folded mop head, and the mop handle can rotate to approach the folded mop head until the two are nearly parallel. This prevents the wringer sleeve from hitting the folded mop head, which would prevent the mop handle and the folded mop head from rotating to overlap. This allows the mop handle and mop head to be used in more positions for cleaning, making it more flexible and efficient.
[0006] Furthermore, the positioning structure provides circumferential and axial positioning for the wringer sleeve and mop handle, ensuring that in the first position, the wringer sleeve and mop handle are anti-rotating and their relative axial positions are defined. This positioning structure prevents the wringer sleeve and mop handle from rotating or moving axially, allowing the wringer sleeve to remain in a fixed position relative to the mop handle without adversely affecting the normal use of the mop handle. This avoids inconvenience caused by the wringer sleeve moving freely relative to the mop handle.
[0007] Furthermore, the positioning structure includes a first elastic locking member that can extend and retract radially along the mop handle, and a locking groove disposed on the wringer sleeve. The first elastic locking member has a first inclined pressing surface and a locking surface, and the locking surface can fall into the locking groove to form a positioning lock between the first elastic locking member and the locking groove. The radial extension and retraction of the first elastic locking member relative to the mop handle facilitates the change of the relative position between the wringer sleeve and the mop handle; the locking surface is at least partially horizontal, thereby forming an effective and stable positioning fit with the locking groove, preventing the wringer sleeve from moving excessively upward relative to the mop handle; the first inclined pressing surface facilitates squeezing and compressing the first elastic locking member back into the mop handle.
[0008] Furthermore, when the wringer sleeve slides relative to the mop handle to the outer periphery of the folding mop head to squeeze and wipe the object, it is in a second position state. A groove is formed on one side of the locking groove, communicating with it, and this groove extends axially away from the folding mop head. The mop handle is provided with a second elastic locking member that can extend and retract radially. In the second position state, the second elastic locking member falls into the groove to achieve an anti-rotation engagement between the wringer sleeve and the mop handle. The engagement of the second elastic locking member and the groove prevents relative rotation between the wringer sleeve and the mop handle, ensuring that the straight edge of the wringer sleeve is perpendicular to the length extension direction of the folding mop head, thus preventing the straight edge of the wringer sleeve from effectively pushing the folding mop head to rotate closer.
[0009] Furthermore, the second elastic locking member has a second inclined pressing surface. When the wringing sleeve moves from the first position to the second position, the wringing sleeve presses the second elastic locking member back into the mop handle through the second inclined pressing surface. The second inclined pressing surface facilitates the pressing of the second elastic locking member into or out of the locking groove.
[0010] Furthermore, the dewatering sleeve includes an outer sleeve and an inner sleeve assembled and connected to the outer sleeve. The inner sleeve forms the groove along the axial direction, and a limiting protrusion is formed on the bottom of the groove relative to the side wall. The limiting protrusion cooperates with the bottom surface of the groove to form a locking groove. The dewatering sleeve is divided into two parts, an outer sleeve and an inner sleeve, which facilitates processing.
[0011] Furthermore, the inner wall of the outer sleeve forms a guide groove that is coaxially connected to the slide groove. The guide groove effectively extends the axial length of the slide groove, ensuring that the anti-rotation fit between the wringer sleeve and the mop handle is maintained even when the wringer sleeve moves a considerable distance downward relative to the mop handle.
[0012] Furthermore, in the second position, the lower end of the inner sleeve abuts against the folding mop head to form an axial positioning of the wringer sleeve and the mop handle. When the wringer sleeve pushes and squeezes the folding mop head to a fully folded state, the inner sleeve abuts against the upper surface of the middle part of the folding mop head, thereby preventing the wringer sleeve from moving further downward.
[0013] Furthermore, the bottom cross-section of the wringer sleeve is square. The square shape allows the two opposite straight edges to push and squeeze the two sides of the folded mop head, resulting in more even force distribution and better squeezing effect on the wiped items.
[0014] Furthermore, in the first position, when the mop handle rotates closer to the folding mop head until they are nearly parallel, the wringer sleeve avoids the folding mop head. When the mop handle rotates to be perpendicular to the folding mop head, because the folding mop head is narrower, it will not interfere with the wringer sleeve. The positioning structure positions the wringer sleeve in the first position of the mop handle, ensuring that the mop handle can rotate to overlap with the folding mop head.
[0015] The beneficial effects of this utility model are: the positioning structure allows the wringer sleeve to be positioned at the first position of the mop handle. At this time, the wringer sleeve avoids the folded mop head, and the mop handle can rotate to approach the folded mop head until the two are nearly parallel. This avoids the wringer sleeve hitting the folded mop head, which would prevent the mop handle and the folded mop head from rotating to overlap. This allows the mop handle and mop head to be used in more positions for cleaning, making it more flexible to use, more efficient in cleaning, and more convenient for users.

Detailed Implementation
[0029] To enable those skilled in the art to better understand the present invention, the technical solutions in 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 a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.
[0030] like Figure 1 , Figure 2As shown, a wringer mop includes a mop handle 1, a folding mop head 2 rotatably connected to the lower end of the mop handle 1, a wiping material 3 mounted on the folding mop head 2, and a wringing sleeve 4 movably mounted around the periphery of the mop handle 1. The wringing sleeve 4 can move downwards relative to the mop handle 1, thereby pushing the folding mop head 2 to rotate closer to squeeze the wiping material 3. The specific structure of the folding mop head 2 can be any existing design, and will not be described in detail here.
[0031] A positioning structure is provided between the wringer sleeve 4 and the mop handle 1. This positioning structure is used to position the wringer sleeve 4 in a first position on the mop handle 1. In this first position, when the mop handle 1 rotates towards the folding mop head 2, the wringer sleeve 4 avoids the folding mop head 2. In other words, in the first position, as... Figure 3 As shown, the distance between the bottom end of the wringer sleeve 4 and the bottom end of the mop handle 1 is defined as H1, and the length of the folded mop head 2 located on one side of the mop handle 1 is defined as H2. Then H1≥H2, so when the mop handle 1 rotates close to the folded mop head 2 until the two are nearly parallel, the wringer sleeve 4 avoids the folded mop head 2, preventing the wringer sleeve 4 from hitting the folded mop head 2 and causing the mop handle 1 and the folded mop head 2 to be unable to rotate to nearly parallel. This allows the mop handle 2 and the mop head 2 to be cleaned in more postures, making them more flexible to use.
[0032] The aforementioned positioning structure only needs to fix the position of the wringer sleeve 4 relative to the mop handle 1; the specific implementation is not limited. In this embodiment, the positioning structure provides circumferential and axial positioning for the wringer sleeve 4 and the mop handle 1, thereby ensuring that in the first position, the wringer sleeve 4 and the mop handle 1 are anti-rotating and their relative axial positions are determined. Of course, in other embodiments, the positioning structure may only need to achieve axial positioning of the wringer sleeve 4 and the mop handle 1; there are no specific limitations.
[0033] like Figure 3 , Figure 4As shown, the positioning structure includes a first elastic locking member 51 that can extend and retract radially along the mop handle 1, and a locking groove 52 provided in the wringer sleeve 4. The first elastic locking member 51 achieves its elastic extension and retraction function by a spring (not shown in the figure) provided between it and the inner wall of the mop handle 1. The first elastic locking member 51 has a first inclined pressing surface 511 and a locking surface 512. The first inclined pressing surface 511 can enable the first elastic locking member 51 to enter the locking groove 52 under the action of external force. At this time, the locking surface 512 can fall into the locking groove 52, thereby forming the positioning and locking of the first elastic locking member 51 and the locking groove 52. Specifically, the locking surface 512 is a horizontal locking surface 512. In order to facilitate the movement of the wringer sleeve 4 relative to the mop handle 1, the locking surface 512 can easily enter the locking groove 52. A guide slope 513 is formed on the outside of the locking surface 52. The horizontal projection length of the guide slope 513 is less than the horizontal projection length of the first inclined extrusion surface 511. This ensures that when the first elastic locking member 51 falls into the locking groove 52, the horizontal locking surface 512 will fall into the locking groove 52 to achieve effective locking of the first elastic locking member 51 and the locking groove 52, and prevent the wringer sleeve 4 from continuing to move upward relative to the mop handle 1.
[0034] like Figures 6-8 As shown, the locking groove 52 is located inside the squeezing sleeve 4. Its lower part is closed and its top is open, and a limiting protrusion 521 is formed at the opening. Thus, under the action of external force, the first elastic locking member 51 can enter the locking groove 52. Once it enters the locking groove 52, the first elastic locking member 51 will not easily disengage from the locking groove 52 without the action of a reverse external force. Only by applying a large external force can the first elastic locking member 51 disengage from the locking groove 52.
[0035] When the wringer sleeve 4 slides relative to the mop handle 1 to the outer periphery of the folding mop head 2 to squeeze the wiping material 3, the wringer sleeve 4 is in the second position. In this embodiment, the bottom cross-section of the wringer sleeve 4 is square. Once the wringer sleeve 4 rotates relative to the mop handle 1, there is a possibility that the corner of the wringer sleeve 4 is directly facing the folding mop head 2. In this case, it is impossible to effectively push the folding mop head 2 to rotate closer to squeeze the wiping material. Only when the straight edge of the wringer sleeve 4 is directly facing the width direction of the folding mop head 2 can the folding mop head 2 be better pushed to rotate. Therefore, in the second position, it is necessary to achieve an anti-rotation engagement between the mop handle 1 and the wringer sleeve 4.
[0036] like Figure 7 , Figure 9As shown, the mop handle 1 is provided with a second elastic locking member 54 that can extend and retract radially. The second elastic locking member 54 is located below the first elastic locking member 51. A groove 53 is formed at the top opening of the locking groove 52, communicating with the locking groove 52. The groove 53 extends upward along the axial direction, that is, it extends along the axial direction away from the folding mop head 2. Thus, in the second position, the second elastic locking member 54 falls into the groove 53, and the two form a circumferential anti-rotation fit, thereby realizing the anti-rotation fit between the wringer sleeve 4 and the mop handle 1. The wringer sleeve 4 can only move up and down along the axis of the mop handle 1, ensuring that the wringer sleeve 4, which has a square cross-section, can effectively push and squeeze the folding mop head 2 by utilizing the extension direction of its straight edge perpendicular to the length extension direction of the folding mop head 2.
[0037] like Figure 5 As shown, in the unfolded state of the folding mop head 2, the second elastic locking member 54 can be inserted into the locking groove 52 to achieve the function of relatively fixing the positions of the wringer sleeve 4 and the mop handle 1. To facilitate the entry and exit of the second elastic locking member 54 from the locking groove 52, it has a second inclined pressing surface 541. In other words, the difference between the second elastic locking member 54 and the first elastic locking member 51 is that the second elastic locking member 54 does not have a horizontal locking surface. When the wringer sleeve 4 changes from the first position state to the second position state, the wringer sleeve 4 presses the second elastic locking member 54 through the second inclined pressing surface 541, causing the second elastic locking member 54 to retract into the mop handle 1. Once the second elastic locking member 54 enters the locking groove 52, the wringer mop can perform normal cleaning work. Applying external force causes the second elastic locking member 54 to enter the sliding groove 53 from the locking groove 52, allowing the wringer sleeve 4 to continue moving downwards relative to the mop handle 1.
[0038] like Figure 6 , Figures 10-12 As shown, the squeezing sleeve 4 includes an outer sleeve 41 and an inner sleeve 42 assembled and connected to the inner side of the outer sleeve 41. The inner sleeve 42 forms the aforementioned groove 53 along the axial direction. The bottom of the groove 53 forms the aforementioned limiting protrusion 521 on the opposite side wall. The limiting protrusion 521 cooperates with the bottom surface of the groove 53 to form a locking groove 52.
[0039] A guide groove 412 is formed on the inner wall of the outer sleeve 41, which is coaxially connected with the slide groove 53. The guide groove 412 is equivalent to extending the axial length of the slide groove 53, which can ensure that the anti-rotation fit between the wringer sleeve 4 and the mop handle 1 can still be guaranteed when the wringer sleeve 4 moves a long distance downward relative to the mop handle 1.
[0040] In the second position, the lower end of the inner sleeve 42 abuts against the upper surface of the folding mop head 2, thereby forming an axial positioning of the wringer sleeve 4 and the mop handle 1. In other words, when the wringer sleeve 4 pushes and squeezes the folding mop head 2 to a fully folded state, the inner sleeve 42 abuts against the upper surface of the middle part of the folding mop head 2, thereby preventing the wringer sleeve 4 from moving further downward.
[0041] This utility model's wringer mop has multiple usage modes. When the folded mop head 2 needs to be unfolded for cleaning, the locking groove 52 of the wringer sleeve 4 can be locked to the second elastic locking member 54 on the mop handle 1. Figure 5 As shown;
[0042] When the folding mop head 2 is unfolded and needs to be rotated to be nearly parallel to the mop handle 1, an external force is applied to the wringer sleeve 4, causing it to move upward relative to the mop handle 1. At this time, the second elastic locking member 54 is squeezed into the mop handle 1 by the wringer sleeve 4 through the second inclined squeezing surface 541, and the first elastic locking member 51 moves in the slide groove 53 until a greater force is applied so that the first elastic locking member 51 falls into the locking groove 52. At this time, the wringer sleeve 4 is in the first position state, and the folding mop head 2 and the mop handle 1 can rotate freely without being interfered with by the wringer sleeve 4.
[0043] When it is necessary to squeeze the wiping material 3, an external force is applied to move the wringing sleeve 4 downward relative to the mop handle 1. Through the limiting protrusion 521 acting on the first inclined squeezing surface 511, the first elastic locking member 51 is squeezed back into the mop handle 1, causing the first elastic locking member 51 to disengage from the locking groove 52 and enter the sliding groove 53. The wringing sleeve 4 continues to move downward relative to the mop handle 1 until the second elastic locking member 54 enters the locking groove 52. Then, through the limiting protrusion 521 acting on the second inclined pressing surface 541, the second elastic locking member 54 is pressed back into the mop handle 1, so that the second elastic locking member 54 disengages from the locking groove 52 and enters the slide groove 53. The wringing sleeve 4 continues to move downward relative to the mop handle 1. At this time, the first elastic locking member 51 and the second elastic locking member 54 both move in the slide groove 53 and the guide groove 412. The wringing sleeve 4 and the mop handle 1 will not rotate relative to each other. Thus, the straight edge of the wringing sleeve 4 can effectively squeeze the folded mop head 2 to realize the wringing operation of the wiping object 3.
[0044] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
