Description

Technical Field

[0001] This utility model belongs to the field of mop bucket technology, and in particular relates to a height-adjustable mop bucket. Background Technology

[0002] Most existing mop cleaning devices adopt a built-in cleaning structure design, such as the mop bucket solution disclosed in Chinese Patent Application No. 202322306847.X, which cleans the mop head by setting a cleaning component inside the bucket. In order to achieve water storage capacity expansion and splash prevention functions, the mop bucket is usually designed with the entire bucket body as a "tall cylindrical" structure.

[0003] While the aforementioned structural design ensures the fulfillment of basic functions, the "tall cylindrical" structure objectively increases the vertical space ratio of the entire mop bucket, resulting in an excessively large overall product volume. This necessitates larger packaging boxes and leads to higher space occupancy during transportation. Especially in bulk shipping scenarios, this structural defect significantly increases packaging and logistics costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, a mop bucket with adjustable overall height is provided, thereby reducing packaging and logistics costs.

[0005] This utility model is achieved using the following technical solution: a height-adjustable mop bucket, comprising:

[0006] The barrel body has a cleaning chamber inside, and the cleaning chamber is equipped with cleaning components;

[0007] A lifting cylinder is movably mounted at the open end of a barrel body. The lifting cylinder has an annular structure adapted to the barrel body, with the two being inner and outer sleeves fitted together. The working state of the lifting cylinder includes:

[0008] The storage state is such that the top of the lifting cylinder is located at the open end of the barrel body;

[0009] The extended state refers to the lifting cylinder moving upward along the axis of the barrel and forming an expanded cleaning chamber;

[0010] A positioning and retaining structure is provided between the barrel body and the lifting cylinder, which is used to stably keep the lifting cylinder in the extended state.

[0011] During packaging and transportation, the lifting cylinder remains retracted, with its top end positioned at the opening of the bucket. This reduces the overall size of the mop bucket, minimizing packaging and transportation costs. Users simply pull the lifting cylinder upwards for use; a retaining structure keeps it extended, providing both water storage capacity and splash protection.

[0012] The positioning and retaining structure can be a snap-fit, a screw-fixed fit, or a spring pin insertion fit.

[0013] The phrase "the top of the lifting cylinder is located at the open end of the barrel" means that the top of the lifting cylinder can be set on the same plane as the open end of the barrel, or the top of the lifting cylinder can be supported on the open end of the barrel.

[0014] The cleaning component can be any component in an existing mop bucket that can clean the mop head.

[0015] Preferably, the positioning and retaining structure includes a slide groove extending in the vertical direction, one end of the slide groove is provided with a locking groove, the slide groove and the locking groove are matched with a fastener, the fastener is slidably fitted in the slide groove, when the lifting cylinder is in the extended state, the fastener is locked in the locking groove, and the locking groove can restrict the vertical movement of the fastener.

[0016] The sliding engagement of the slide groove and the fastener guides the lifting and lowering of the lifting cylinder. One end of the slide groove has a slot that restricts the vertical movement of the fastener, thus maintaining the extended position of the lifting cylinder. The slot can be located on the lifting cylinder, and the fastener on the cylinder body; or the slot can be on the cylinder body, and the fastener on the lifting cylinder. The slot can have the same depth as the slide groove, separated by a blocking element, or the slot can be deeper than the slide groove, allowing the fastener to engage in a deeper slot.

[0017] Preferably, the slot and the slide have the same depth, and the slot and the slide are separated by a blocking protrusion.

[0018] This setup makes processing more convenient.

[0019] Preferably, the blocking protrusion has an inclined first guide slope on both sides, and the buckle has a second guide slope on both sides that is adapted to the first guide slope.

[0020] By setting the first guide slope and the second guide slope, the fastener can easily pass over the blocking protrusion and enter the slide or slot through its own deformation, so that the user can switch the working state of the lifting cylinder.

[0021] Preferably, a limiting structure is provided between the barrel and the lifting cylinder to restrict their radial positions; the limiting structure includes a limiting groove extending in the vertical direction, the limiting groove includes a wide section and a narrow section, the narrow section is located outside the wide section, the limiting groove is matched with a limiting member, the limiting member includes a thick section and a thin section, the thick section slides within the wide section, and the thin section slides within the narrow section.

[0022] By setting a limiting structure, the radial position of the bucket and the lifting cylinder can be constrained, thereby ensuring that the lifting cylinder will not detach from the bucket and that the snap-fit ​​components in the positioning and holding structure are always slidably fitted within the groove. The limiting groove can be a T-shaped groove, an L-shaped groove, etc.

[0023] Preferably, the cleaning chamber of the barrel has a vertically extending cleaning chamber wall, and the lifting cylinder has a vertically extending expansion chamber wall. The expansion chamber wall has a shape adapted to the cleaning chamber wall, the expansion chamber wall fits into the cleaning chamber wall, and the expansion chamber wall always overlaps with the cleaning chamber wall in the radial direction.

[0024] The above settings ensure the integrity and aesthetics of the cleaning chamber before and after expansion. At the same time, the constant fit between the two also guides the lifting of the cylinder, preventing it from shifting.

[0025] Preferably, the lifting cylinder is provided with a lifting mating wall located outside the expansion cavity wall, and the positioning and retaining structure and the limiting structure are provided between the lifting mating wall and the cylinder body; the lifting mating wall is located inside the cylinder body or outside the cylinder body.

[0026] The lifting mechanism is used to achieve the lifting and lowering coordination with the barrel body.

[0027] Preferably, the open end of the barrel is fixed with an annular connector, which is fixed on the inner or outer wall of the barrel. The annular connector is provided with a positioning and retaining structure and a limiting structure that cooperate with the lifting cylinder.

[0028] Directly machining the positioning and limiting structures onto the barrel body might be difficult and would require thicker barrel walls, wasting materials and increasing production costs. Therefore, a separate annular connector is used. This connector is fixed to the barrel body, and the positioning and limiting structures are mounted on it. The barrel body and lifting cylinder are indirectly connected via this connector, which saves on production costs. The fixing method can include adhesive, clips, screws, and nuts, etc.

[0029] Preferably, the lifting cylinder is rotatably connected to a handle, and the handle has a shape adapted to the inner wall of the lifting cylinder; when the handle is not in use, the outer wall of the handle is in contact with the inner wall of the lifting cylinder.

[0030] The addition of a handle makes it easy for users to pull up the lifting cylinder.

[0031] Preferably, the lifting cylinder is provided with a radially extending first blocking part, and the barrel or annular connector is provided with a radially extending second blocking part. The first blocking part and the second blocking part have overlapping portions in the axial direction. When the first blocking part and the second blocking part abut against each other, the lifting cylinder is in the extreme position of the extended state.

[0032] By setting the first and second blocking parts to abut against each other, the lifting cylinder can be constrained, preventing the lifting cylinder from separating from the barrel body.

[0033] Compared with the prior art, the beneficial effects of this utility model are: this solution uses the lifting cylinder and the opening area of ​​the bucket to lift and cooperate, so that the lifting cylinder is in a retracted state during transportation and packaging, so that the lifting cylinder is located inside the bucket, making the volume of the entire mop bucket smaller, thereby saving transportation and packaging costs.

[0049] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0050] Example 1

[0051] like Figures 1 to 4 As shown, Embodiment 1 discloses a height-adjustable mop bucket, including a bucket body 1. The inner circumferential cross-sectional shape of the bucket body 1 is rectangular, and the corners of the bucket body 1 are designed with rounded corners. The interior of the bucket body 1 forms a cleaning chamber for inserting a mop head. A cleaning assembly 3 is provided within the cleaning chamber; the cleaning assembly 3 can be any existing assembly capable of cleaning the mop head. Two vertically extending cleaning chamber walls 11 are provided within the cleaning chamber. The cleaning chamber walls 11 are arc-shaped and located circumferentially outside the cleaning assembly 3.

[0052] A lifting cylinder 2 is installed at the opening end of the barrel 1. The lifting cylinder 2 is coaxially arranged with the barrel 1 and vertically extends through its center. The lifting cylinder 2 has two vertically extending expansion chamber walls 21, which have a shape adapted to the cleaning chamber wall 11. The expansion chamber walls 21 fit snugly against the cleaning chamber wall 11, and always overlap with the cleaning chamber wall 11 in the radial direction. A handle 4 is rotatably connected to the inner wall of the central hole of the lifting cylinder 2. The handle 4 has a shape adapted to the inner wall of the lifting cylinder 2. When the handle 4 is not in use, the outer wall of the handle 4 contacts the inner wall of the lifting cylinder 2, and the handle 4 is flush with the upper end face of the lifting cylinder 2.

[0053] The lifting cylinder 2 also has a lifting mating wall 22 located outside the expansion chamber wall 21. The lifting mating wall 22 has a shape adapted to the side wall of the barrel 1, and is located circumferentially inside the barrel 1. The working states of the lifting cylinder 2 include: a retracted state where the top of the lifting cylinder 2 is located at the open end of the barrel, and an extended state where the lifting cylinder 2 moves upward along the axis of the barrel 1 to form an expanded cleaning chamber. When the lifting cylinder 2 moves vertically, the expansion chamber wall 21 and the cleaning chamber wall 11 are always in contact.

[0054] like Figures 1 to 8 As shown, an annular connector 5 is also fixed at the open end of the barrel 1. The annular connector 5 has an annular structure and is adapted to the shape of the barrel 1. The annular connector 5 is fixed on the inner wall of the barrel. The outer circumferential wall of the annular connector 5 is provided with a number of annularly evenly spaced wedge-shaped buckles 51. The circumferential wall of the barrel 1 is provided with a number of buckle holes 13 that engage with the wedge-shaped buckles 51. The annular connector 5 is fixed to the barrel 1 by engaging the wedge-shaped buckles 51 with the buckle holes 13.

[0055] The annular connector 5 is provided with a positioning and retaining structure and a limiting structure between it and the lifting and lowering mating wall 22 of the lifting cylinder 2.

[0056] The positioning and retaining structure includes a slide groove 61 extending vertically on the lifting and engaging wall 22. A slot 62 is provided at the lower end of the slide groove 61. The slot 62 and the slide groove 61 have the same depth and are separated by a blocking protrusion 63. A fastening element 52 is fitted to the slide groove 61 and the slot 62, and the fastening element 52 can slide within the slide groove 61 or be engaged within the slot 62. The blocking protrusion 63 has inclined first guide slopes 631 on both sides, and the fastening element 52 has second guide slopes 521 on both sides that are adapted to the first guide slopes 631. When the lifting cylinder 2 is in the extended state, the fastening element 52 is engaged within the slot 62, which restricts the vertical movement of the fastening element 52. The annular connector 5 has gaps on both sides of the fastening element 52, facilitating its own deformation.

[0057] A limiting structure is used to restrict the radial position of the annular connector 5 and the barrel 1. The limiting structure includes a limiting groove 7 extending vertically, which is disposed on the lifting cylinder 2. The circumferential inner edge cross-sectional shape of the limiting groove 7 is L-shaped, and the limiting groove 7 includes a wide section 71 and a narrow section 72, with the narrow section 72 located outside the wide section 71. The limiting groove 7 is fitted with a limiting member 53, which is disposed on the inner wall of the annular connector 5. The limiting member 53 is also L-shaped, and includes a thick section 531 and a thin section 532. The thick section 531 slides within the wide section 71, and the thin section 532 slides within the narrow section 72.

[0058] like Figure 2 As shown, the upper inner wall of the annular connector 5 is provided with a first blocking portion 23 extending radially inward. The first blocking portion 23 is an annular protrusion. Several second blocking portions 12 extending radially outward are provided on the lower outer wall of the lifting mating wall 22. All second blocking portions 12 are at the same height and are wedge-shaped protrusions. The second blocking portions 12 and the first blocking portions 23 overlap in the axial direction. When the lifting cylinder 2 extends upward to its limit, the second blocking portion 12 abuts against the first blocking portion 23, preventing the lifting cylinder 2 from extending further upward. When the lifting cylinder 2 descends, the upper flange of the lifting cylinder 2 abuts against the first blocking portion 23, thereby limiting the maximum descent position of the lifting cylinder 2.

[0059] In some other embodiments, the annular connector 5 can be fixed to the outside of the barrel 1, while the lifting and lowering mating wall 22 is located outside the annular connector 5, and the above-mentioned positioning and retaining structure and limiting structure are provided between the annular connector 5 and the lifting and lowering mating wall 22.

[0060] Example 2

[0061] like Figure 9 and Figure 10 As shown, the difference between Embodiment 2 and Embodiment 1 is that Embodiment 2 does not include the annular connector 5; the barrel 1 and the lifting cylinder 2 are in direct contact. The aforementioned positioning and limiting structure (not shown in the drawings) is provided between the barrel 1 and the lifting cylinder 2. Several annularly spaced first blocking portions 23 are provided on the inner wall of the opening of the barrel 1. Each first blocking portion 23 is a radially inwardly extending protrusion. A second blocking portion 12 is provided on the lower outer wall of the lifting mating wall 22. The second blocking portion 12 is a ring-shaped protrusion. The first blocking portions 23 and the second blocking portions 12 can limit the upward extension limit of the lifting cylinder 2.

[0062] Example 3

[0063] like Figures 11 to 14As shown, the difference between Embodiment 3 and Embodiment 1 is that Embodiment 3 does not include the annular connector 5, and the lifting and lowering mating wall 22 in Embodiment 3 is located on the outside of the barrel 1. The lifting and lowering mating wall 22 and the barrel 1 are provided with the aforementioned positioning and retaining structure and limiting structure. The barrel 1 is provided with a vertically extending sliding groove 61, a locking groove 62, and a limiting groove 7. The inner wall of the lifting and lowering mating wall 22 is provided with a fastener 52 and a limiting element 53 (not shown in the figure).

[0064] A first blocking part 23 is provided on the outer wall of the opening end of the barrel 1. The first blocking part 23 is a ring-shaped protrusion. A second blocking part 12 is provided on the inner wall of the lifting and fitting wall 22. The second blocking part 12 is a wedge-shaped protrusion that can abut against the ring-shaped protrusion of the first blocking part 23, thereby limiting the extreme position of the lifting cylinder 2 extending upward.

[0065] When the mop bucket needs to be packaged and transported, the packing personnel can press down on the lifting cylinder 2 to retract it, allowing the entire mop bucket to be packaged and transported. When the mop bucket needs to be used, the handle 4 can be pulled up to lift the entire lifting cylinder 2 upwards.
