Description

Technical Field

[0001] This utility model relates to the field of cleaning tools technology, specifically to a multi-directional swingable mop handle downward drive mechanism. Background Technology

[0002] Floor cleaning is a basic requirement for environmental maintenance, and mops, as a core cleaning tool, have become widely used. Currently, mainstream mops adopt a rotary wringing design, which drives the rotating rod on the mop handle to rotate the chuck at high speed, using centrifugal force to achieve efficient dehydration of the chuck, solving the problems of traditional mops being laborious to wring out and leaving a lot of water residue.

[0003] However, existing rotary spin-dry mops have significant drawbacks: the mop bucket is usually directly and fixedly connected to or linked with the rotating rod of the mop handle. To achieve stable rotation and spin-drying of the chuck, the mop bucket must have a specially designed spin-drying seat adapted to the chuck structure. This spin-drying seat needs to have positioning, limiting, and transmission adaptation functions to ensure that the chuck does not shift or shake during high-speed spin-drying. This directly leads to: a more complex mop bucket structure, requiring the design of an adaptation structure based on the chuck size and rotation trajectory, increasing design difficulty and manufacturing costs; and dead corners such as gaps and grooves in the spin-drying seat, where wastewater and impurities ejected from the chuck are easily left behind, difficult to clean with regular rinsing, and prone to bacterial growth and odors with long-term use, significantly increasing the difficulty of mop bucket maintenance and reducing the user experience. In addition, when cleaning narrow spaces such as corners, behind furniture, and around the toilet, adjusting the mop direction is cumbersome because the existing mop handle can only swing in two directions. Utility Model Content

[0004] In view of this, the present invention proposes a multi-directional swingable mop handle downward drive mechanism, which is applied to the mop handle to improve the flexibility of the mop handle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0014] Optionally, the fixed cylinder includes an upper cylinder and a lower cylinder. The lower cylinder includes an outer cylinder section and an inner cylinder section arranged coaxially.

Detailed Implementation

[0030] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. Identical components are indicated by the same reference numerals.

[0031] Please see Figures 1 to 8 This utility model embodiment provides a multi-directional swingable mop handle pressing drive mechanism for an independent rotating mop handle, which includes a fixed cover 10, a cylindrical shaft 20 and a rotating shaft 30.

[0032] like Figure 5-7 As shown, the fixed cover 10 has a first cavity 101 with an open bottom end. The first cavity 101 has a bushing 50 fixedly connected to the top surface of the fixed cover 10. The top surface of the fixed cover 10 has a through hole 102 communicating with the first cavity 101. The top surface of the fixed cover 10 has a fixed bearing 103 fixedly mounted around the through hole 102. The central axes of the bushing 50, the through hole 102 and the fixed bearing 103 are collinear.

[0033] The cylindrical shaft 20 includes a fixed cylindrical body and a hinged cylindrical shaft 23. The top end of the hinged cylindrical shaft 23 is hinged to the bottom end of the fixed cylindrical body, and the bottom end of the hinged cylindrical shaft 23 is hinged to the fixed shaft seat 103. The rotating shaft 30 includes a helical rod 31, a first connecting shaft 32, and a second connecting shaft 33 arranged coaxially from top to bottom. The helical rod 31 and the first connecting shaft 32 are fitted inside the cylindrical shaft 20. The bottom of the second connecting shaft 33 moves through the through hole 102 and is rotatably disposed in the bushing 50. The top end of the first connecting shaft 32 is hinged to the bottom end of the helical rod 31, and the bottom end of the first connecting shaft 32 is hinged to the top end of the second connecting shaft 33. The hinged cylindrical shaft 23 is collinear with the hinge axis of the fixed cylindrical body, and the helical rod 31 is collinear with the hinge axis of the first connecting shaft 32. The hinged cylindrical shaft 23 is collinear with the hinge axis of the fixed shaft seat 103, and the hinge axis of the first connecting shaft 32 is collinear with the hinge axis of the second connecting shaft 33.

[0034] In this embodiment, the multi-directional swinging mop handle downward drive mechanism allows the cylinder shaft 20 and the rotating shaft 30 to swing simultaneously along the central axis of the hinge axis between the spiral rod 31 and the first connecting shaft 32, or simultaneously along the central axis of the hinge axis between the first connecting shaft 32 and the second connecting shaft 33. This achieves multi-directional bending rather than swinging in a single plane, greatly improving the mop's flexibility and adaptability to complex cleaning scenarios.

[0035] like Figure 3 and Figure 4 As shown, in this embodiment, the axis of the hinge shaft 23 and the hinge shaft of the fixed cylinder body, and the axis of the hinge shaft 23 and the hinge shaft of the fixed shaft seat 103 are spatially perpendicular to each other. This allows the cylinder shaft 20 and the rotating shaft 30 to bend in four basic directions (such as front, back, left, and right), with an included angle of approximately 90 degrees between each direction. This structure not only reduces the overall height of the mop handle, making it easier to clean and store compactly in low spaces (such as under furniture), but also allows users to adjust their operating posture more freely, reducing user fatigue.

[0036] like Figure 8 As shown, the bushing 50 includes an annular body 501, two symmetrical connecting ears 502 integrally provided on the outer annular wall of the annular body 501, and an annular platform 503 integrally provided on the inner annular wall of the annular body 501. The bushing 50 is fixed in the first cavity 101 by screws that pass through the two connecting ears 502 and are embedded in the studs of the fixing cover 10. The bottom outer wall of the second connecting shaft 33 is provided with a limiting ring 331. The top surface of the limiting ring 331 abuts against the inner top surface of the fixing cover 10, and the bottom surface of the limiting ring 331 abuts against the annular platform 503, so that the second connecting shaft 33 can only be rotatably disposed in the bushing 50, thereby realizing the limiting of the second connecting shaft 33, and thus realizing that the rotating shaft 30 is disposed in the second cavity in a manner that can be rotated horizontally but cannot be moved axially.

[0037] like Figure 2 , Figure 6 as well as Figure 7 It also includes a pressure rod 40, the bottom end of which is placed inside the cylinder shaft 20 and axially slides against the inner wall of the fixed cylinder, and is helically driven by the screw rod 31. Specifically, the linear reciprocating motion of the pressure rod 40 and the helical engagement with the rotating shaft 30 convert the linear downward pressure into a rotational driving force, thereby enabling the pressure rod 40 to move up and down and drive the rotating shaft 30 to rotate.

[0038] More specifically, the pressing rod 40 includes a hollow rod body 41 and a drive sleeve 42. The drive sleeve 42 includes an inner sleeve body 421 and a sliding ring 422 fixed to the outer wall of the bottom end of the inner sleeve body 421. The outer wall of the sliding ring 422 is axially slidingly engaged with the inner wall of the fixed cylinder. The inner sleeve body 421 is fixedly fitted to the inner wall of the bottom end of the hollow rod body 41. The center axis of the inner sleeve body 421 is provided with a through hole 423 that engages with the screw groove of the screw rod 31. When the pressing rod 40 moves linearly relative to the cylinder shaft 20, the linear motion is converted into the rotational motion of the screw rod 31 through the engagement of the through hole 423 with the screw rod 31. The transmission efficiency is high and the response is rapid.

[0039] like Figure 2 As shown, the fixed cylinder includes an upper cylinder 21 and a lower cylinder 22. The lower cylinder 22 includes an outer cylinder section 221 and an inner cylinder section 222 coaxially arranged. The inner cylinder section 222 is sleeved on the inner wall of the lower section of the upper cylinder 21, and its outer wall has two protrusions 223 spaced apart circumferentially. The lower section of the upper cylinder 21 has connecting holes 211 that are adapted to the two protrusions 223. The inner cylinder section 222 and the upper cylinder 21 are fixedly connected by the snap-fit ​​engagement of the protrusions 223 and the connecting holes 211. Specifically, both the upper cylinder 21 and the lower cylinder 22 are made of ABS or PP plastic, which has a certain degree of elasticity, allowing the upper cylinder 21 and the lower cylinder 22 to be connected by a snap-fit ​​method.

[0040] In this embodiment, the bottom end of the lower cylinder 22, both ends of the hinge cylinder shaft 23, and the fixed shaft seat 103 are all U-shaped fork structures. This structure not only provides stable support for each hinge point, but also makes the swinging motion smooth and synchronous, effectively avoiding motion interference, and ultimately realizing the rapid and compact swinging of the whole device, improving the convenience of operation and the portability of the product.

[0041] like Figure 2 and Figure 7 As shown, in this embodiment, the inner wall of the upper cylinder 21 includes a small diameter section 212 and a large diameter section 213 from top to bottom. The inner cylinder section 222 is fixedly fitted inside the bottom inner wall of the large diameter section 213. The outer wall of the sliding ring 422 is slidably engaged with the inner wall of the large diameter section 213. The stepped surfaces of the small diameter section 212 and the large diameter section 213 are the upper limit of the stroke of the sliding ring 422, and the top surface of the inner cylinder section 222 is the lower limit of the stroke of the sliding ring 422. Setting the inner wall of the upper cylinder 21 to have a small diameter section 212 and a large diameter section 213 not only facilitates the installation and insertion of the drive sleeve 42, but more importantly, it limits the stroke range of the drive sleeve 42, preventing excessive pressure or rebound that could damage the mechanism, and ensuring the safety and lifespan of the device.

[0042] like Figure 6 and Figure 7As shown, in this embodiment, an elastic element 60 is also included. The elastic element 60 is sleeved outside the spiral rod 31. One end of the elastic element 60 presses against the lower top surface of the drive sleeve 42, and the other end of the elastic element 60 presses against the connecting surface of the outer cylinder section 221 and the inner cylinder section 222. The elastic element 60 is configured to be compressed when the lowering rod 40 moves down, and to provide an upward restoring force for the lowering rod 40.

[0043] Specifically, the elastic element 60 is preferably a compression spring. After the downward pressure is released, the reset function of the elastic element 60 automatically pushes the downward pressure rod 40 to move upward quickly, reducing the manual lifting force and improving the convenience and efficiency of operation. At the same time, it can also buffer the downward pressure process, improve the operating feel, and reduce the impact damage to internal parts. In addition, the constant elastic force helps to maintain reliable engagement between the drive sleeve 42 and the helical rod 31, preventing accidental disengagement and ensuring the continuity of power transmission.

[0044] The technical solution of this utility model has been described in detail above with reference to specific embodiments. The specific embodiments described are used to help understand the concept of this utility model. Derivations and modifications made by those skilled in the art based on the specific embodiments of this utility model also fall within the protection scope of this utility model.
