Description

Technical Field

[0001] This utility model relates to the field of cleaning bucket technology, and in particular to a cleaning bucket. Background Technology

[0002] In daily life and cleaning operations, cleaning buckets are commonly used containers for holding wastewater, cleaning agents, and tools. Their ease of use and stability directly affect cleaning efficiency and the user experience. Currently, most cleaning buckets on the market are designed with a single handle fixed in the middle of the bucket to ensure the bucket body and handle are relatively parallel during extraction. The intention of this design is to maintain the balance of the bucket body by centrally distributing force, preventing tilting caused by a shift in the center of gravity during extraction.

[0003] However, the above design has significant limitations: the length of the handle is directly constrained by the width or length of the cleaning bucket itself. Since the handle needs to connect to the middle of the bucket, its length is often limited to half the length or width of the bucket, and cannot be extended further. This limitation directly leads to technical problems in practical use. When lifting the cleaning bucket using the handle, the shorter handle results in an excessively short lever arm between the low point of application of force and the bucket's center of gravity, causing the bucket to wobble easily during lifting and movement. Especially when the rectangular bucket contains a small amount of wastewater, the wobbling amplitude will further increase, easily causing wastewater to spill out. This not only pollutes the environment and increases the extra cleaning burden, but also poses a safety hazard as the user may slip due to splashing wastewater. Utility Model Content

The first end of each limiting portion is rotatably connected to the first sidewall, and the second end is connected to the connecting end, so that there is an angle between the handle portion and the limiting portion.

[0036] In summary, the beneficial technical effects of this utility model are as follows:

[0037] By designing a bucket body, a reference plane is set within the bucket body to form a second reference point on the bucket body. A handle is movably connected to the bucket body, and this handle is divided into a lifting part and a limiting part. The lifting part and the limiting part are connected, and the limiting part is movably connected to the bucket body. When the lifting part is driven, it moves the limiting part relative to the bucket body until the limiting part and the bucket body form a limiting or supporting position, resulting in a stable relative position between the lifting part and the bucket body, the lifting part is located above the bucket body. A first reference point is formed on the lifting part through the reference plane. This first reference point and... The line connecting the second reference point forms the first line, and the line connecting the first reference point and its projection point on the placement surface forms the second line. An angle α is formed at the first reference point of the handle by the first and second lines. With the opposite side of the angle α unchanged, the smaller the angle α between the first and second lines, the longer the length of the second line, and the higher the lifting point of the handle relative to the bucket body. After lifting, the lever arm between the point of force application and the center of gravity of the bucket is longer, thereby solving the problem of the existing cleaning bucket handle being too short and the lifting point being too low.

[0059] The following is combined Figures 1-7 The embodiments shown illustrate the technical solution of this utility model:

[0060] like Figure 1 ,2 As shown, a cleaning bucket includes a bucket body 10 and a handle 20. The bucket body 10 has a space for holding cleaning materials or cleaning agents. The bucket body 10 has a rectangular structure. The handle 20 includes a lifting handle 21 and two limiting parts 22 respectively disposed at both ends of the lifting handle 21. The two limiting parts 22 are movably connected to two first side walls of the bucket body 10. When the lifting handle 21 is driven, the two limiting parts 22 move relative to the bucket body 10 until the two limiting parts 22 form a limiting and / or support with the two first side walls, so that the lifting handle 21 and the bucket body 10 have a stable relative position, and the bucket body 10 is driven away from the placement plane.

[0061] like Figure 1 As shown, a reference surface A1 is set in the barrel 10, and the reference surface A1 is perpendicular to the line connecting the centers of the two first side walls. The center of the area where the reference surface A1 intersects with the handle 21 is taken as the first reference point A2, the center of the area where the reference surface A1 intersects with the upper edge of the barrel 10 is taken as the second reference point A3, and the center of the area where the reference surface A1 intersects with the bottom edge of the barrel 10 is taken as the third reference point A4. The line connecting the first reference point A2 and the second reference point A3 is taken as the first line, the line connecting the first reference point A2 and its projection point A5 on the placement surface is taken as the second line, and the line connecting the first reference point A2 and the third reference point A4 is taken as the third line. When the handle 20 is driven to move relative to the barrel 10 and forms a stable relative position on the barrel 10 with limitation and / or support, an angle α is formed between the first line and the second line, and an angle b is also formed between the second line and the third line.

[0062] The angle α between the first and second lines can be 15 ≤ a ≤ 40° or 25 ≤ a ≤ 35°. The angle b between the second and third lines varies with the angle α, and can be greater than or equal to 1 / 2 of a, less than or equal to 4 / 5 of a, or greater than or equal to 3 / 5 of a, less than or equal to 4 / 5 of a.

[0063] In one embodiment, optionally, when the length of the opposite side of the included angle α is 40cm and the included angle α is 15°, the depth of the barrel 10 is limited to 25cm, and the length of the line connecting the first reference point A2 of the handle portion 21 to the center of the two first side walls is 149cm.

[0064] Optionally, when the length of the opposite side of the included angle a is 40cm and the included angle a is 40°, the depth of the barrel 10 is limited to 25cm, and the length of the line connecting the first reference point A2 of the handle part 21 to the center of the two first side walls is 48cm.

[0065] Optionally, when the length of the opposite side of the included angle α is 40cm and the included angle α is 27°, the depth of the barrel 10 is limited to 25cm, and the length of the line connecting the first reference point A2 of the handle 21 to the center of the two first side walls is 79cm.

[0066] In this embodiment, when the included angle α is 15°, the line connecting the lifting point of the handle 21 to the center of gravity of the barrel 10 is 174cm; when the included angle α is 40°, the line connecting the lifting point of the handle 21 to the center of gravity of the barrel 10 is 73cm; and when the included angle α is 27°, the line connecting the lifting point of the handle 21 to the center of gravity of the barrel 10 is 104cm, thus limiting the distance from the bottom of the barrel 10 to the placement surface after it is lifted to 10cm.

[0067] When the line connecting the lifting point of the handle 21 to the center of gravity of the barrel 10 is 174cm, a person with a height of 165-185cm cannot lift the barrel 10 off the placement surface when using the lifting point of the handle 21, and thus the barrel 10 is dragged along the placement surface when moved. When the line connecting the lifting point of the handle 21 to the center of gravity of the barrel 10 is 73cm, a person with a height of 165-185cm will find that the distance from the bottom of the barrel 10 to the placement surface after being lifted is much greater than 10cm, making the lifted barrel 10 relatively high relative to the placement surface. When the line connecting the lifting point of the handle 21 to the center of gravity of the barrel 10 is 104cm, when a person with a height of 165-185cm lifts the barrel 10 through the lifting point of the handle 21, the distance from the bottom of the barrel 10 to the placement surface after being lifted is less than or equal to 10cm or greater than or equal to 10cm.

[0068] In other words, when the included angle is 27°, the height at which it is lifted during use is most suitable, and the lifting point height of the handle 21 is also most reasonable. This makes it convenient for different people to use in real life, and also makes it easy to store the handle 20 after use.

[0069] In another embodiment, optionally, when the length of the opposite side of the included angle α is 40cm and the included angle α is 25°, the depth of the barrel 10 is limited to 25cm, and the length of the line connecting the first reference point A2 of the handle portion 21 to the center of the two first side walls is 86cm.

[0070] Optionally, when the length of the opposite side of the included angle α is 40cm and the included angle α is 35°, the depth of the barrel 10 is limited to 25cm, and the length of the line connecting the first reference point A2 of the handle 21 to the center of the two first side walls is 57cm.

[0071] Optionally, when the length of the opposite side of the included angle α is 40cm and the included angle α is 27°, the depth of the barrel 10 is limited to 25cm, and the length of the line connecting the first reference point A2 of the handle 21 to the center of the two first side walls is 79cm.

[0072] In this embodiment, when the included angle α is 25°, the line connecting the lifting point of the handle 21 to the center of gravity of the barrel 10 is 111cm; when the included angle α is 35°, the line connecting the lifting point of the handle 21 to the center of gravity of the barrel 10 is 82cm; and when the included angle α is 27°, the line connecting the lifting point of the handle 21 to the center of gravity of the barrel 10 is 104cm, thus limiting the distance from the bottom of the barrel 10 to the placement surface after it is lifted to 10cm.

[0073] When the line connecting the lifting point of the handle 21 to the center of gravity of the barrel 10 is 111cm, a person with a height of 165-185cm cannot lift the barrel 10 off the placement surface when using the lifting point of the handle 21. When the line connecting the lifting point of the handle 21 to the center of gravity of the barrel 10 is 82cm, a person with a height of 165-185cm cannot lift the barrel 10 off the placement surface when using the lifting point of the handle 21, as the distance from the bottom of the barrel 10 to the placement surface is much greater than 10cm, making the barrel 10 relatively high after being lifted. When the line connecting the lifting point of the handle 21 to the center of gravity of the barrel 10 is 104cm, a person with a height of 165-185cm can lift the barrel 10 off the placement surface when using the lifting point of the handle 21, as the distance from the bottom of the barrel 10 to the placement surface is close to 10cm.

[0074] In other words, when the included angle is 27°, the height at which it is lifted during use is most suitable, and the lifting point height of the handle 21 is also most reasonable. This makes it convenient for different people to use in real life, and also makes it easy to store the handle 20 after use.

[0075] like Figure 2 As shown, in one embodiment, the handle 20 includes a lifting portion 21 and two limiting portions 22. Each limiting portion 22 includes a first rod 221 and a second rod 222. The first ends of the first rod 221 and the second rod 222 are rotatably connected to the first sidewall. The second end of the first rod 221 is movably connected to the second end of the second rod 222, and the lifting portion 21 is connected to the second end of the first rod 221.

[0076] Furthermore, the handle 21 is fixedly connected to the second end of the first rod 221, and there is an angle between the handle 21 and the first rod 221, such that when the handle 21 is above the bucket body 10, the line connecting the first reference point A2 and the center of gravity of the cleaning bucket is parallel to the gravity line, and the angle between the handle 21 and the first rod 221 is greater than or equal to 90°. At the same time, the handle 21 and the second end of the first rod 221 are integrally formed and connected, and the handle 21 is set with a "U" shaped structure.

[0077] It is understandable that the handle 21 is driven to rotate the first rod 221 and the second rod 222 of the two limiting parts 22 relative to the first side wall. The second end of the first rod 221 moves relative to the second end of the second rod 222, so that the first rod 221 and the second rod 222 form an isosceles triangle with the edge of the first side wall, and the handle 21 is located above the barrel body 10.

[0078] That is, the second end of the first rod 221 is slidably connected to the second end of the second rod 222; the handle 21 is driven to rotate the first rod 221 and the second rod 222 of the two limiting parts 22 relative to the first side wall, and the second end of the first rod 221 slides relative to the second end of the second rod 222, so that the first rod 221 and the second rod 222 form an isosceles triangle with the edge of the first side wall.

[0079] Specifically, such as Figure 3 and 4 As shown, a groove a2220 is formed through the second end of the second rod 222 along the rod body, and a sliding head 223 is provided at the second end of the first rod 221 corresponding to the groove a2220. The first ends of the first rod 221 and the second rod 222 are rotatably hinged to the two ends of the first side wall along the length direction, and the second ends of the first rod 221 and the second rod 222 are slidably connected to the groove a2220 through the sliding head 223. When the handle part 21 is driven, the first rod 221 and the second rod 222 of the two limiting parts 22 are driven. When the two rods 222 rotate relative to the first sidewall, the second end of the first rod 221 slides in the second end groove a2220 of the second rod 222 through the sliding head 223, so that the first rod 221 and the second rod 222 form an isosceles triangle at the edge of the first sidewall, and the handle 21 is positioned above the barrel 10, so that the line connecting the first reference point A2 on the handle 21 to the center of gravity of the barrel 10 always remains perpendicular to the placement surface, thereby forming a triangle between the handle 20 and the barrel 10 during the lifting process. Figure 1 The angle relationship shown is such that the angle α is controlled at 27° during the extraction process, making the first reference point A2 of the handle 21 higher than the center of gravity of the barrel 10, thus forming a high lifting point. This allows the barrel 10 to remain balanced even when the water in the barrel 10 decreases during use, solving the problem that the barrel 10 is prone to shaking and water is prone to spilling when the water in the rectangular barrel 10 decreases.

[0080] like Figure 5 As shown, in another embodiment, each limiting part 22 includes a first rod 221 and a second rod 222. The first end of the first rod 221 is rotatably connected to the first sidewall, the first end of the second rod 222 is rotatably connected to the second end of the first rod 221, the second end of the second rod 222 is movably connected to the first sidewall, and the handle part 21 is connected to the second end of the first rod 221.

[0081] Understandably, the handle 21 is driven to move the first rod 221 and the second rod 222 of the two limiting parts 22 relative to each other, so that the first end of the first rod 221 rotates relative to the first side wall, the first end of the second rod 222 rotates relative to the second end of the first rod 221, and the second end of the second rod 222 slides relative to the first side wall, so that the first rod 221 and the second rod 222 form an isosceles triangle with the edge of the first side wall, and the handle 21 is located above the barrel body 10.

[0082] Specifically, a groove a2220 is formed on the second rod 222, and a sliding head 223 is provided on the first sidewall corresponding to the groove a2220. The first end of the first rod 221 is rotatably hinged to one end of the first sidewall, and the first end of the second rod 222 is rotatably hinged to the second end of the first rod 221, so that the first rod 221 and the second rod 222 can rotate at the second end of the first rod 221. At the same time, the second end of the second rod 222 is slidably fitted onto the sliding head 223 at one end of the first sidewall, so that the sliding head 223 can slide along the groove a2220 on the second rod 222. When the handle 21 is driven to rotate relative to the first side wall and the second end of the first rod 221 and the second rod 222 of the two limiting parts 22, the sliding head 223 on the first side wall slides along the sliding groove a2220 at the second end of the second rod 222, so that the first rod 221 and the second rod 222 form an isosceles triangle at the edge of the first side wall, and the handle 21 is positioned above the barrel 10, so that the line connecting the first reference point A2 on the handle 21 to the center of gravity of the barrel 10 remains perpendicular to the placement surface, thereby forming a gap between the handle 20 and the barrel 10 during the lifting process. Figure 1 The angle relationship shown is such that the angle α is controlled at 27° during the extraction process, making the first reference point A2 of the handle 21 higher than the center of gravity of the barrel 10, thus forming a high lifting point. This allows the barrel 10 to remain balanced even when the water in the barrel 10 decreases during use, solving the problem that the barrel 10 is prone to shaking and water is prone to spilling when the water in the rectangular barrel 10 decreases.

[0083] like Figure 6As shown, in another embodiment, a groove b100 is formed along the length direction at one end of the two opposing first sidewalls of the barrel 10, and the length of the groove b100 is 1 / 3 of the length of the barrel 10. At the same time, a sliding head 223 is provided at one end of the second rod 222 corresponding to the groove b100. The first end of the first rod 221 is rotatably hinged to the first sidewall, and the second end of the first rod 221 is rotatably hinged to the end of the second rod 222 away from the sliding head 223, so that the first rod 221 and the second rod 222 can rotate relative to each other. At the same time, the sliding head 223 on the second rod 222 is slidably embedded in the groove b100, and the handle 21 is connected to the second end of the first rod 221.

[0084] Understandably, when the handle 21 is driven to rotate relative to the first side wall and the second end of the first rod 221 and the second rod 222 of the two limiting parts 22, the sliding head 223 on the second rod 222 slides along the groove b100 on the first side wall, so that the first rod 221 and the second rod 222 form an isosceles triangle at the edge of the first side wall, so that the handle 21 is located above the barrel body 10.

[0085] Specifically, a groove b100 is formed along the length of the first sidewall. A sliding head 223 is provided at one end of the second rod 222 corresponding to the groove b100. The first end of the first rod 221 is rotatably hinged to the first sidewall, and the second end of the first rod 221 is rotatably hinged to the end of the second rod 222 away from the sliding head 223, so that the first rod 221 and the second rod 222 can rotate relative to each other. At the same time, the sliding head 223 of the second rod 222 is slidably embedded in the groove b100 on the first sidewall. When the first rod 221 and the second rod 222 rotate relative to the first sidewall and the second end of the first rod 221, the sliding head 223 on the second rod 222 slides along the groove b100 on the first sidewall, causing the first rod 221 and the second rod 222 to form an isosceles triangle at the edge of the first sidewall, and positioning the handle 21 above the barrel 10, ensuring that the line connecting the first reference point A2 on the handle 21 to the center of gravity of the barrel 10 remains perpendicular to the placement surface, thus forming a triangle between the handle 20 and the barrel 10 during lifting. Figure 1 The angle relationship shown is such that the angle α is controlled at 27° during the extraction process, making the first reference point A2 of the handle 21 higher than the center of gravity of the barrel 10, thus forming a high lifting point. This allows the barrel 10 to remain balanced even when the water in the barrel 10 decreases during use, solving the problem that the barrel 10 is prone to shaking and water is prone to spilling when the water in the rectangular barrel 10 decreases.

[0086] like Figure 1 and 7As shown, in another embodiment, the handle 20 includes a lifting portion 21 and two limiting portions 22. The lifting portion 21 has a gripping area 211 and a connecting end 212 away from the gripping area 211. The first end of each limiting portion 22 is rotatably connected to the first sidewall, and the second end is connected to the connecting end 212, so that there is an angle between the lifting portion 21 and the limiting portion 22. When the lifting portion 21 is driven to rotate relative to the first sidewall until the second end of the limiting portion 22 abuts against the first sidewall, the limiting portion 22 and the first sidewall form at least two points of support, and the gripping area 211 of the lifting portion 21 is located above the center of gravity of the barrel 10.

[0087] It is understood that each limiting part 22 includes a first rod 221, and the first end of the first rod 221 is rotatably connected to the first side wall, and the second end is connected to the connecting end 212 of the handle part 21, so that there is an angle between the handle part 21 and the first rod 221. At the same time, the angle between the handle part 21 and the first rod 221 is greater than or equal to 90°. Moreover, a limiting block 2210 is provided at the second end of the first rod 221, so that when the handle part 21 is driven to rotate the first rod 221 relative to the first side wall, the limiting block 2210 at the second end of the first rod 221 abuts against the first side wall, so that the first rod 221 and the first side wall form at least two points of support, and the gripping area 211 of the handle part 21 is located above the center of gravity of the barrel body 10.

[0088] Optionally, the first end of the first member 221 is rotatably disposed at the end of the first sidewall away from the center position, and the length of the first member 221 is less than or equal to 1 / 2 the length of the first sidewall.

[0089] In other words, when the length of the first rod 221 is less than 1 / 2 the length of the first side wall, the handle 21 is driven to rotate relative to the first side wall until the limiting block 2210 at the second end of the first rod 221 abuts against the first side wall away from the center, and the handle 21 and the first side wall form an angle of less than 90° relative to each other, so that the gripping area 211 of the handle 21 is located above the center of gravity of the barrel 10, and the line connecting the first reference point A2 on the handle 21 to the center of gravity of the barrel 10 is always perpendicular to the placement surface.

[0090] In other words, when the length of the first rod 221 is equal to 1 / 2 the length of the first side wall, the handle 21 is driven to rotate the first rod 221 relative to the first side wall until the limiting block 2210 at the second end of the first rod 221 abuts against the center position of the first side wall, and the handle 21 and the first side wall are relatively perpendicular, so that the gripping area 211 of the handle 21 is located above the center of gravity of the barrel 10, and the line connecting the first reference point A2 on the handle 21 to the center of gravity of the barrel 10 is always perpendicular to the placement surface.

[0091] To ensure that the gripping area 211 on the handle 21 is at its highest point relative to the center of gravity of the barrel 10 during extraction, thereby maximizing the extraction process, the gripping area 211 on the handle 21 is positioned at its highest point relative to the center of gravity of the barrel 10. Figure 1 The included angle α in the shown angle relationship is controlled at 27°, which makes the first reference point A2 of the handle 21 higher than the center of gravity of the bucket 10, thus forming a high lifting point. This allows the bucket 10 to remain balanced even when the water in the bucket 10 decreases during use, solving the problem that the bucket 10 is prone to shaking and water is prone to spilling when the water in the rectangular bucket 10 decreases.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
