Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, specifically to a cleaning bucket with a unique handle and stable structure that is specially adapted to the needs of mop cleaning. Background Technology

[0002] In the practical process of cleaning operations, mops are widely used as the main floor cleaning tool in many situations. Long mops, in particular, are favored for their ability to efficiently clean large areas of flooring due to their large cleaning coverage. However, the washing of long mops has long been plagued by problems caused by the unreasonable design of the accompanying cleaning bucket.

[0003] Traditional cleaning bucket designs often prioritize versatility, failing to fully optimize for the characteristics of long mops. Because long mops are significantly longer than ordinary cleaning tools, the corresponding cleaning buckets are typically elongated to ensure the mop can be fully immersed and rinsed. However, in everyday mop washing, these elongated buckets frequently need to be filled with large amounts of water or detergent solution. When full, the bucket's weight increases dramatically. When users carry the bucket by the handle, the lack of effective restraint means that even slight external forces—such as body swaying during walking, natural arm swings, or bumps from uneven surfaces—can cause the handle to rotate or shift relative to the bucket, resulting in violent shaking and potentially tipping over.

[0004] Therefore, in order to meet the needs of cleaning long mops, there is an urgent need to develop a cleaning bucket that can effectively solve the problem of tipping over when transporting long cleaning buckets filled with liquid, and truly improve the convenience, stability and safety of using the cleaning bucket. Utility Model Content

[0005] This application aims to address, to some extent, the technical problem in existing technologies where cleaning buckets easily tip over, causing liquid to spill. To this end, this application provides a cleaning bucket, including a bucket body and a handle.

[0006] The barrel body is provided with a staggered insertion part and a positioning part, and the insertion part includes a rotating part and a stopping part that are interconnected.

[0007] The handle is provided with a pivot and a mating part at an offset. When the pivot is inserted into the plug-in part and mated with the rotating part, the pivot and the rotating part are rotatably connected so that the handle and the bucket body can rotate relative to each other. When the pivot moves from the rotating part in the plug-in part to mating with the anti-rotor part, the anti-rotor part limits the rotation of the pivot to restrict the relative rotation between the handle and the bucket body.

[0008] The relative rotation of the rotating shaft and the rotating sub-part can drive the mating part to move. When the mating part moves to the position corresponding to the positioning part, the rotating shaft can move from the rotating sub-part to engage with the anti-rotor part, and the mating part corresponding to the positioning part moves to the position of abutting and engaging with the positioning part. The handle is positioned on the barrel body by the abutting and engaging of the mating part and the positioning part, and by the anti-rotation limit of the rotating shaft and the anti-rotor part.

[0009] In some embodiments, the positioning part is formed as a downward-opening groove on the barrel body, and the mating part is formed as a protrusion on the handle. When the mating part moves to a position corresponding to the positioning part, the mating part can move into the positioning part to engage.

[0010] In some embodiments, the opening sides of the positioning part further include arcuate edges that are symmetrical to the positioning part. The arcuate edges are located on a circumference centered on the rotating shaft, and the distance between the arcuate edges and the rotating part does not exceed the distance between the mating part and the rotating shaft.

[0011] In some embodiments, the positioning part is located above the insertion part, and the opening of the positioning part further includes guide grooves communicating with the positioning part on both sides. The arcuate edge is formed as the lower edge of the guide groove. When the handle rotates relative to the barrel body, the mating part moves within the guide groove; or

[0012] The positioning part is located below the insertion part. The barrel body includes a downwardly bent flange. The insertion part is located on the flange. The positioning part is formed as a downward-opening groove below the flange. The arc edge is the lower edge of the flange. When the handle rotates relative to the barrel body, the mating part slides along the arc edge.

[0013] In some embodiments, when the barrel body includes a downwardly bent flange, the insertion part is located on the flange, the positioning part is formed as a downwardly opening groove below the flange, and the arc edge is the lower edge of the flange, a retaining edge is also provided on the flange at the end of the arc edge away from the insertion part. When the mating part slides along the arc edge to abut against the retaining edge, the handle stops rotating.

[0014] In some embodiments, a rotation retainer is also included, which restricts the pivot within the insertion portion when the handle rotates relative to the barrel body.

[0015] In some embodiments, the rotor stop portion includes a vertically extending strip-shaped hole with a width smaller than the diameter of the rotating shaft, and the rotation holding portion is formed as the sidewall at the connection between the rotatable rotor portion and the strip-shaped hole.

[0016] In some embodiments, the rotating shaft also includes an anti-rotation surface that mates with the strip hole. This anti-rotation surface is formed as two opposing outer surfaces extending vertically on the rotating shaft when the mating part moves to a position corresponding to the positioning part. This allows the rotating shaft to move from the rotating part in the insertion part to mate with the strip hole, so that when the rotating shaft moves from the rotating part to mate with the strip hole, the strip hole abuts against the anti-rotation surface through its two side hole walls to achieve the anti-rotation limiting of the rotating shaft by the anti-rotation part.

[0017] In some embodiments, the rotor stop portion includes a strip-shaped hole extending vertically and having a width not less than the diameter of the shaft, and the rotation holding portion is formed as a protrusion within the strip-shaped hole.

[0018] In some embodiments, the rotating shaft is provided with a vertically extending anti-rotation groove when the mating part moves to the position corresponding to the positioning part. The anti-rotation part also includes a vertically extending protruding rib located within the anti-rotation part, so that when the rotating shaft moves from the rotating part in the insertion part to engage with the strip hole, the anti-rotation groove is located within the strip hole to achieve anti-rotation and limiting of the rotating shaft by the anti-rotation part. The rotation holding part is the lower end face of the protruding rib.

[0019] The cleaning bucket in this application has a handle that rotates relative to the bucket body via a pivot and a connecting part. This allows for easy adjustment of the handle's position in different usage scenarios. When the pivot moves from the rotating part to the non-rotating part and engages with the positioning part, the handle is stably positioned on the bucket body. This avoids the inconvenience caused by the handle's inability to rotate to either side of the bucket body when the connecting part only has a rotating part in the prior art. Furthermore, the two-point positioning is achieved through the engagement of the pivot and the non-rotating part, as well as the engagement of the connecting part with the positioning part. This improves upon the problem in the prior art where the engagement of only the pivot and the non-rotating part results in a small rotational torque, causing a large impact on the pivot and shortening its lifespan.

[0040] This application is described below with reference to the accompanying drawings and specific embodiments:

[0041] like Figure 1-4As shown, the cleaning bucket provided in this application includes a bucket body 1 and a handle 2. The bucket body 1 is generally made of durable plastic material and is injection molded to ensure a stable overall structure and good corrosion resistance, capable of withstanding the erosion of various chemical reagents and daily bumps in cleaning scenarios. Its shape is a common rectangle, oval, or other similar shape with an open top, convenient for holding cleaning water, cleaning solution, etc. The symmetrical sides of the bucket body 1 are staggered with insertion parts 11 and positioning parts 12. The insertion part 11, as a key part connecting to the handle 2, has a rotating part 111 and a stop part 112 that are interconnected. The rotating part 111 is a smooth, circular hole, the size of which matches the diameter of the rotating shaft 21 on the handle 2, ensuring smooth rotation after the rotating shaft 21 is inserted, maintaining stable rotational fit, and effectively avoiding axial and radial wobbling. The stop part 112 is also hole-shaped and communicates with the rotating part 111; its size is preferably such that the rotating shaft 21 can move in. The handle 2 is generally a U-shaped structure, with a pivot 21 and a mating part 22 offset on both ends. The pivot 21 is a cylinder that can be inserted into the insertion part 11 of the barrel 1. Its length is adapted to the depth of the insertion part 11 to ensure a stable fit after full insertion. The mating part 22 is designed to fit the positioning part 12 and can abut and engage with the positioning part 12. When the handle 2 rotates, the rotating shaft 21 rotates within the rotating sub-part 111, thereby driving the mating part 22 to move synchronously. When the mating part 22 rotates to correspond to the position of the positioning part 12 of the bucket body 1, the rotating shaft 21 can move from the rotating sub-part 111 into the anti-rotor part 112. The anti-rotor part 112 can then limit the rotation of the rotating shaft 21, preventing the handle 2 from rotating relative to the bucket body 1. At the same time, the mating part 22 abuts and engages with the positioning part 12, further limiting the handle 2 from rotating relative to the bucket body 1. Through the anti-rotation limitation of the rotating shaft 21 by the anti-rotor part 112 and the engagement of the positioning part 12 with the mating part 22, a double restriction is formed on the relative rotation of the handle 2 relative to the bucket body 1. On the one hand, this avoids the problem of the single-weight restriction in the prior art causing greater damage to the product and shortening the life of the rotating shaft 21. On the other hand, the handle 2 of this design can rotate to both sides relative to the bucket body 1, thereby improving the user experience.

[0042] In this embodiment, as Figure 2 , Figure 3 As shown, the positioning part 12 is formed as a downward-opening groove on the barrel body 1, and the groove extends vertically along the long side of the barrel body 1 for a certain length, such as... Figure 2 , Figure 4As shown, the mating part 22 is formed as a protruding structure at the end of the handle 2. When the mating part 22 is rotated to correspond to the position of the positioning part 12 of the barrel body 1, since the user is holding the handle 2, the mating part 22 can slide into the groove of the positioning part 12. Therefore, the groove opening of the positioning part 12 can be provided with a slight guide bevel with an angle between 30 and 45 degrees, which acts like a "slide" to guide the mating part 22 to accurately enter the groove, thereby reducing the difficulty of aligning the mating part 22 when it enters the groove of the positioning part 12.

[0043] In this embodiment, as Figure 3 As shown, the positioning part 12 has symmetrically distributed arc-shaped edges 13 on both sides of the opening. These edges are located on a circle centered on the rotating shaft 21, and the distance between the arc-shaped edge 13 and the rotating part 111 does not exceed the distance between the mating part 22 and the rotating shaft 21. That is, the position of the arc-shaped edge 13 on the circumference matches the rotation trajectory of the mating part 22, ensuring the continuity of the rotation of the handle 2 and avoiding structural interference. In the product, it is preferable that the distance between the arc-shaped edge 13 and the rotating part 111 is slightly smaller than the distance between the mating part 22 and the rotating shaft 21, for example, the difference is controlled within 1-2 mm. This ensures that the arc-shaped edge 13 can "guide" the trajectory of the mating part 22 as it moves with the rotation of the rotating shaft 21. The surface of the arc-shaped edge 13 is relatively smooth, which can reduce wear on the mating part 22. In addition, the arc-shaped edge 13 is provided on both sides of the opening of the positioning part 12, so that when the mating part 22 is disengaged from the positioning part 12, the handle 2 can rotate relative to the barrel 1 on both sides of the rotating shaft 21. This avoids the inconvenience caused by the prior art, where the arc-shaped edge 13 is only provided on one side of the positioning part 12, requiring the user to distinguish the rotation direction of the handle 2 when putting it down, or the damage to the rotating shaft 21 or the mating part 22 caused by the user forcibly rotating the handle 2 to the other side when the user does not notice that the handle 2 can only rotate relative to one side of the barrel 1.

[0044] In this embodiment, as Figure 2 , Figure 3 As shown, the positioning part 12 is located below the insertion part 11. The barrel body 1 is provided with a downwardly bent flange 15. This flange 15 reinforces the edge structure of the barrel body 1 on the one hand, and bears the connecting function on the other hand, that is, the structure that connects and cooperates with the handle 2 is set on it. Among them, the positioning part 12 is a downward-opening groove below the flange 15, and the arc-shaped edge 13 is the lower edge of the flange 15. This setting effectively utilizes the structure of the flange 15 of the barrel body 1, which can reduce the processing cost without affecting the structural strength of the product itself.

[0045] In another embodiment of this application, such as Figure 5 , Figure 6As shown, the positioning part 12 is located above the insertion part 11. Its downward-opening groove has guide grooves 14 connected to both sides. The guide grooves 14 form the moving track for the mating part 22. The lower edge of the guide groove 14 is an arc-shaped edge 13, allowing the mating part 22 to move smoothly while providing a certain limiting constraint to prevent the mating part 22 from shifting and causing the handle 2 and the bucket body 1 to jam during rotation. Since both the guide groove 14 and the positioning part 12 form a closed groove, they need to be installed on the wall of the bucket body 1. The edge of the bucket body 1 cannot be used. Therefore, a flange 15 can be provided on the bucket body 1 to enhance the edge structural strength of the bucket body 1. The guide groove 14 and the positioning part 12 can be placed on the flange 15. Alternatively, the flange 15 can be omitted, and the guide groove 14 can be directly installed on the side wall of the bucket body 1. However, the latter method requires the structural strength of the bucket body 1 to meet certain requirements.

[0046] In this embodiment, as Figure 3 As shown, on the flange 15, at the end of the arc-shaped edge 13 away from the insertion part 11, a retaining edge 16 is specially added. The retaining edge 16 limits the length of the arc-shaped edge 13. When the mating part 22 moves along the arc-shaped edge 13 to the position of the retaining edge 16, it stops moving. At this time, on the one hand, the movement of the mating part 22 on the handle 2 is limited by the retaining edge 16, and on the other hand, since the pivot 21 is located inside the rotating part 111, the continued rotation of the handle 2 is limited at both points. And since the distance between the gripping part of the handle 2 and the pivot 21 is relatively small compared to the distance between the mating part 22 and the pivot 21, the handle 2 is further restricted from rotating. Since the handles 2 on both sides of the pivot 21 are relatively far apart, they form a "lever structure" with the pivot 21 as the fulcrum. The "lever structure" has a smaller weight at the end of the mating part 22, and its upper side abuts against the retaining edge 16 through the mating part 22. The weight is larger at the end of the grip part, but since the mating part 22 abuts against the retaining edge 16, the end of the grip part will not continue to fall. Therefore, during use, the setting of the retaining edge 16 can prevent the handle 2 from rotating excessively and causing the grip part to contact the ground. On the one hand, it keeps the grip part clean and hygienic, and on the other hand, it makes it convenient for the user to grip the grip part.

[0047] In this embodiment, as Figure 3 , Figure 9 As shown, since the insertion part 11 includes a rotating sub-part 111 and a stop-rotor part 112 that are connected, when the handle 2 rotates relative to the barrel 1 but does not rotate to the position corresponding to the mating part 22 and the positioning part 12, it is necessary to prevent the rotating shaft 21 from entering the stop-rotor part 112 from the rotating sub-part 111. Therefore, a rotation holding part 3 is provided at the connection between the stop-rotor part 112 and the rotating sub-part 111 to keep the rotating shaft 21 in the rotating sub-part 111.

[0048] In this embodiment, such as 3, Figure 6As shown, the anti-rotation part 112 is a key part for controlling the anti-rotation state of the rotating shaft 21. It includes a strip-shaped hole 1121 that extends vertically and has a width smaller than the diameter of the rotating shaft 21. This not only meets the subsequent special anti-rotation fit requirements, but also effectively prevents the rotating shaft 21 from entering at unexpected times, ensuring the stability of the normal rotation stage. In this structure, the rotation holding part 3 is the side wall at the connection between the rotating part 111 and the strip-shaped hole 1121.

[0049] In this embodiment, as Figure 4 , Figure 7 As shown, the rotating shaft 21 is a component that rotatably connects the barrel body 1 and the handle 2. It is a solid cylinder with a stop-rotation surface 211 on it. This stop-rotation surface 211 is formed by "cutting" a portion off the cylindrical side of the rotating shaft 21. Generally, there are two stop-rotation surfaces 211, which are two opposing sides. When the mating part 22 moves to the position corresponding to the positioning part 12, the stop-rotation surface 211 extends vertically. Obviously, in order for the rotating shaft 21 to enter the slotted hole 1121 of the stop-rotation part 112, the distance between the two stop-rotation surfaces 211 should not exceed the width of the slotted hole 1121. Alternatively, when there is only one stop-rotation surface 211, the maximum dimension of the rotating shaft 21 along the direction perpendicular to the stop-rotation surface 211 should not exceed the width of the slotted hole 1121. This ensures that when the mating part 22 moves to the position corresponding to the positioning part 12, the rotating shaft 21 can smoothly enter the slotted hole 1121 of the stop-rotation part 112. Simultaneously, because... The side edge of the strip hole 1121 extends in the same direction as the anti-rotation surface 211. Therefore, the side edge of the strip hole 1121 can limit the anti-rotation surface 211, thereby limiting the rotation of the shaft 21 within the anti-rotation part 112. At this time, on the one hand, the side edge of the strip hole 1121 limits the anti-rotation surface 211, thereby preventing the anti-rotation part 112 from stopping the rotation of the shaft 21. On the other hand, the positioning part 12 limits the mating part 22, thus effectively preventing the problem of easy shaking of the barrel 1 caused by the gap between the shaft 21 and the anti-rotation part 112 due to the use of the side edge of the strip hole 1121 to limit the rotation of the anti-rotation surface 211 in the prior art, or the problem of easy jamming of the rotation between the handle 2 and the barrel 1 due to the use of the positioning part 12 to limit the mating part 22.

[0050] In yet another embodiment of this application, as Figure 9As shown, the anti-rotor part 112 is a key part for controlling the anti-rotation state of the rotating shaft 21. It includes a strip-shaped hole 1121 extending vertically and with a width not less than the diameter of the rotating shaft 21. That is, without the rotation retaining part 3, no matter what angle the handle 2 rotates relative to the barrel 1, the rotating shaft 21 can enter the strip-shaped hole 1121 of the anti-rotor part 112. Obviously, in this state, the function of the handle 2 cannot be completed without the rotation retaining part 3. Therefore, the rotation retaining part 3 is formed as a protrusion in the anti-rotor part 112. It should overlap with the rotating shaft 21 in the vertical direction and be located at the connection between the strip-shaped hole 1121 of the anti-rotor part 112 and the rotating part 111. When the rotating shaft 21 is rotated, the rotation retaining part 3 always presses the rotating shaft 21 into the rotating part 111 until the mating part 22 moves to the position corresponding to the positioning part 12.

[0051] Furthermore, in the above embodiment, in order to allow the rotating shaft 21 to enter the slot 1121 of the rotating part 111 when the mating part 22 moves to the position corresponding to the positioning part 12, a rotation-stopping groove 212 is provided on the rotating shaft 21. When the mating part 22 moves to the position corresponding to the positioning part 12, the rotation-stopping groove 212 extends vertically, that is, the protrusion of the rotation-holding part 3 can pass into the rotation-stopping groove 212 in this state. At the same time, in order to limit the rotation of the rotating shaft 21 when it enters the slot 1121 of the rotation-stopping part 112, the rotation-stopping part 112 also includes a vertically extending rib 1122. When the rotating shaft 21 enters the slot 1121 of the rotation-stopping part 112, the rib 1122 enters the rotation-stopping groove 212, and the side wall of the rotation-stopping groove 212 and the rib 1122 form a limit to restrict the rotation of the rotating shaft 21. The relative rotation with the anti-rotation part 112 means that in this state, the rotation holding part 3 can be set as the lower end of the rib 1122, that is, the lower end of the rib 1122 should extend to the connection between the strip hole 1121 and the rotating part 111. Similar to the previous embodiment, at this time, on the one hand, a limit is formed between the rib 1122 and the anti-rotation groove 212, so that the anti-rotation part 112 stops the rotation of the shaft 21. On the other hand, the positioning part 12 limits the mating part 22, thereby effectively preventing the problem of easy shaking of the barrel 1 caused by the anti-rotation limit between the rib 1122 and the anti-rotation groove 212 in the prior art, or the problem of easy jamming of the rotation between the handle 2 and the barrel 1 caused by only using the anti-rotation limit between the rib 1122 and the anti-rotation groove 212 in the prior art, or the problem of easy jamming of the rotation between the handle 2 and the barrel 1 caused by only using the positioning part 12 to limit the mating part 22.

A cleaning bucket according to claim 4, characterized in that, When the barrel body (1) includes a downwardly bent flange (15), the insertion part (11) is located on the flange (15), the positioning part (12) is formed as a downwardly opening groove below the flange (15), and the arc edge (13) is the lower edge of the flange (15), a retaining edge (16) is also provided on the flange (15) at the end of the arc edge (13) away from the insertion part (11). When the mating part (22) slides along the arc edge (13) to abut against the retaining edge (16), the handle (2) stops rotating.

6. A cleaning bucket according to any one of claims 1-5, characterized in that, It also includes a rotation retaining part (3), which restricts the rotating shaft (21) within the insertion part (11) when the handle (2) rotates relative to the barrel body (1).

7. A cleaning bucket according to claim 6, characterized in that, The rotor stop part (112) is formed as a strip hole (1121) extending vertically and with a width smaller than the diameter of the shaft (21), and the rotation holding part (3) is formed as the side wall at the connection between the rotatable part (111) and the strip hole (1121).

8. A cleaning bucket according to claim 7, characterized in that, The rotating shaft (21) also includes an anti-rotation surface (211) that mates with the strip hole (1121). It is formed such that when the mating part (22) moves to the position corresponding to the positioning part (12), the two opposite outer surfaces of the rotating shaft (21) extend vertically. This is so that when the rotating shaft (21) moves from the rotating part (111) in the insertion part (11) to mate with the strip hole (1121), the strip hole (1121) abuts against the anti-rotation surface (211) through the two side hole walls to achieve the anti-rotation limiting of the rotating shaft (21) by the anti-rotation part (112).

9. A cleaning bucket according to claim 6, characterized in that, The rotor stop part (112) includes a strip-shaped hole (1121) extending vertically and having a width not less than the diameter of the shaft (21), and the rotation holding part (3) is formed as a protrusion inside the strip-shaped hole (1121).

10. A cleaning bucket according to claim 9, characterized in that, The rotating shaft (21) is provided with a vertically extending anti-rotation groove (212) when the mating part (22) moves to the position corresponding to the positioning part (12). The anti-rotation part (112) also includes a vertically extending rib (1122) located in the anti-rotation part (112), so that when the rotating shaft (21) moves from the rotating part (111) in the insertion part (11) to engage with the strip hole (1121), the anti-rotation groove (212) is located in the strip hole (1121) to realize that the anti-rotation part (112) limits the rotation of the rotating shaft (21). The rotation holding part (3) is the lower end face of the rib (1122).
