Description

Technical Field

[0001] This utility model relates to the field of mop technology, to a squeezing and cleaning mop, and more particularly to a one-way rolling squeezing and cleaning mop. Background Technology

[0002] A squeeze mop is a cleaning tool that uses a squeezing motion to clean and dry the mop head.

[0003] Some squeeze cleaning mops, such as the multi-faceted rotating mop disclosed in patent CN201572058U, consist of a rotating mop head, a bracket, and a hand handle. The rotating mop head is prismatic and consists of two turntables, a rotating shaft connecting the turntables, and a crossbar connecting the turntables. A bushing is provided in the center of the frame, and the rotating shaft passes through the bushings of the two turntables, which are linked together. The two ends of the rotating shaft extend out of the turntables and pass through the two vertical sides of the bracket, which are flexibly connected to them. A hand handle is fixedly installed in the middle of the bracket, and a pull ring is installed on the bracket with a traction hole. A rotating device is installed on the rotating shaft between the vertical side of the bracket and the turntable on the same side as the traction hole. The rotating device is connected to the lifting rod installed in the middle of the hand handle through a traction line.

[0004] The rotating device includes a driving dial, a driven dial, and a stop plate. The driven dial is a disc, with a rotating core connected to the inner surface of one side of the disc. On the outer surface of the driven dial, there is a groove corresponding to the core corner of the rotating core. The driven dial and the rotating core are fitted onto a rotating shaft and are connected to the shaft. The driving dial is close to the outside of the driven dial. The driving dial is a disc with a pull rod, which is also fitted onto the rotating shaft but is not connected to the shaft. A traction line is attached to the outer end of the pull rod. The other end of the traction line passes through a traction hole and a pull ring in sequence and is connected to a lifting rod. A return torsion spring is fitted on the rotating shaft between the driving dial and the vertical side of the bracket. One end of the return torsion spring is connected to the driving dial, and the other end is connected to the vertical side of the bracket. A stop plate bracket is also installed on the aforementioned vertical side of the bracket, and a vertically downward stop plate is installed on the stop plate bracket.

[0005] This patent designs the rotating mop head into a prism-shaped structure, so that when one side of the rotating mop head is in contact with the ground while mopping, the rotating mop head will not rotate.

[0006] However, based on the rotating device of this patent, in order to avoid the rotating mop head from rotating when mopping the floor, the rotating mop head can only adopt a polygonal column structure, which makes the mop unable to be used with cylindrical mop heads, resulting in low compatibility. Utility Model Content

[0007] This invention addresses the problem that existing rotary mops can only be adapted to mop heads with polygonal cylindrical structures, resulting in low compatibility. The technical problem to be solved by this invention is to provide a unidirectional rolling extrusion cleaning mop that can improve the compatibility of mop heads.

[0008] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a one-way rolling squeezing cleaning mop, including a mop handle and a mop head shell connected to the mop handle;

[0009] The mop head housing is rotatably mounted with a cleaning drum and a traction component. The traction component and the cleaning drum are connected by a one-way bearing that rotates freely in one direction and is locked in the other direction.

[0010] The mop handle is provided with a movable and restrictive pull rod, which is rotatably connected to the traction component. The axis of the traction component rotatably connecting the pull rod and the axis of the traction component rotatably connecting the mop head housing are coaxial but opposite in axis.

[0011] Pulling or pushing the lever causes the traction component to rotate forward, and the traction component, through a one-way bearing, causes the cleaning drum to rotate; and when the lever is reset, it drives the traction component to rotate in reverse and reset, and the cleaning drum does not rotate.

[0012] A further preferred embodiment of this utility model is: the mop handle is hollow, and the outer shell of the mop head has a through hole that communicates with the interior of the mop handle; the pull rod is located in the mop handle and is rotatably connected to the traction member.

[0014] A further preferred embodiment of this utility model is: the mop handle has a movable opening, the pull rod is located inside the mop handle and extends out of the movable opening, and is rotatably connected to the operating handle.

[0015] A further preferred embodiment of this utility model is: the operating handle is provided with a hinge part one that is rotatably connected to the mop handle, a hinge part two that is rotatably connected to the pull rod, and an operating part that can be subjected to force. The hinge part two is located between the hinge part one and the operating part, and the distance between the operating part and the hinge part two is greater than the distance between the hinge part one and the hinge part two.

[0016] A further preferred embodiment of this utility model is: the mop head housing is provided with a connecting part, the traction member is rotatably connected to the connecting part, and the one-way bearing is fixed on the traction member.

[0017] A further preferred embodiment of this utility model is: the cleaning drum includes a load shell, a first rotating connector disposed at one end of the load shell, a second rotating connector disposed at the other end of the load shell, and a cleaning layer surrounding the outer ring of the load shell.

[0018] A further preferred embodiment of this utility model is: a brush and a squeegee limiting component are installed on the outer shell of the mop head, the brush is attached to the cleaning layer, and the squeegee limiting component squeezes the cleaning layer and leaves a gap between it and the load shell.

[0019] A further preferred embodiment of this utility model is: the mop head housing includes a main frame and side frames that are plugged into and installed on both sides of the main frame, the connecting part is disposed on the main frame, and the cleaning drum is located between the side frames and the connecting part or the traction component.

[0020] Another technical solution adopted by this utility model to solve the above-mentioned technical problems is: a one-way rolling squeezing cleaning mop, including a hollow mop handle, an operating handle rotatably installed on the mop handle, a mop head shell rotatably or fixedly installed at the lower end of the mop handle, a traction component rotatably installed on the mop head shell, a pull rod rotatably connected to the operating handle and the traction component inside the mop handle, a one-way bearing installed on the traction component, and a cleaning drum rotatably installed on the mop head shell and connected to the one-way bearing.

[0021] The operating handle is operated by rotating it in the forward direction. The operating handle pulls or pushes the traction component to rotate in the forward direction via a pull rod, and the traction component can drive the cleaning drum to rotate via a one-way bearing.

[0022] Furthermore, when the operating handle is rotated in the opposite direction, the operating handle is pulled or pushed by the pull rod to reverse and reset the traction component, and the cleaning drum does not rotate.

[0023] Compared with the prior art, the advantages of this utility model are that, through the installation and setting of the mop head shell, mop handle, pull rod, traction component, one-way bearing and cleaning drum, after limiting the pull rod, the cleaning drum will not rotate due to friction with the ground when it contacts the ground for mopping. It can realize the shape of the cleaning drum without restriction, that is, the cleaning drum can be used for both polygonal column structure and cylindrical structure, effectively improving the adaptability of cleaning drums of different shapes.

[0032] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0033] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0034] This embodiment mainly describes a one-way rolling squeeze cleaning mop that can improve the adaptability of mop heads, as detailed below:

[0035] like Figure 1-6As shown, the one-way rolling squeezing cleaning mop includes a mop handle 1 for holding when mopping, a mop head housing 2 fixed to the lower end of the mop handle 1, an operating handle 3 rotatably mounted on the mop handle 1, and a cleaning drum 5, a traction member 6, and a one-way bearing 7 rotatably mounted on the mop head housing 2. The mop head housing 2 is provided with a connecting pipe 21, and the mop handle 1 is fixed by inserting the connecting pipe 21. A pull rod 4 is connected between the operating handle 3 and the traction member 6. The pull rod 4 is rotatably connected to both the operating handle 3 and the traction member 6, and the one-way bearing 7 connects the cleaning drum 5 and the traction member 6.

[0036] Preferably, the mop head housing 2 can be rotatably mounted on the lower end of the mop handle 1, and a universal joint can be connected between the pull rod 4 and the traction component 6 to achieve rotation.

[0037] The operating handle 3 is provided with a first hinge 31, a second hinge 32, and an operating part 32. The second hinge 32 is located between the first hinge 31 and the operating part 32. The operating handle 3 is rotatably connected to the mop handle 1 through the first hinge 31 and rotatably connected to the pull rod 4 through the second hinge 32. In order to reduce the force when the operating handle 3 is flipped up or down, the distance between the operating part 32 and the second hinge 32 is set to be greater than the distance between the first hinge 31 and the second hinge 32. Preferably, the short distance between the first hinge 31 and the second hinge 32 is set so that when the operating part 32 of the operating handle 3 is not subjected to external force, the friction force of the cleaning drum 5 contacting the ground is fed back to the pull rod 4, and this feedback force is not enough to make the operating handle 3 rotate.

[0038] In other embodiments, the pull rod 4 is disposed in the mop handle 1, and the operating handle 3 can be disposed on the upper end of the mop handle 1 and threadedly installed. By rotating the thread, the operating handle 3 can pull the pull rod 4 to move.

[0039] In this embodiment, when the operating part 32 of the operating handle 3 is subjected to an external force and flips upward relative to the mop handle 1, the operating handle 3 drives the traction member 6 to rotate upward through the pull rod 4, and the traction member 6 drives the cleaning drum 5 to rotate through the one-way transmission force of the one-way bearing 7; when the operating part 32 of the operating handle 3 is subjected to an external force and flips downward relative to the mop handle 1, the operating handle 3 drives the traction member 6 to rotate downward through the pull rod 4, and the characteristics of the one-way bearing 7 prevent it from driving the cleaning drum 5 to rotate.

[0040] In this application, by installing the mop head housing 2, mop handle 1, pull rod 4, traction component 6, one-way bearing 7, and cleaning drum 5, after limiting the pull rod 4, the cleaning drum 5 will not rotate due to friction with the ground when it contacts the ground for mopping. This allows for unlimited shape of the cleaning drum 5, meaning that the cleaning drum 5 can be used for both polygonal and cylindrical structures, effectively improving the adaptability of cleaning drums 5 with different shapes.

[0041] like Figure 2-5As shown, the mop handle 1 is hollow and has a movable opening 11 that connects to the inside of the mop handle 1. The mop head housing 2 has a through hole 22 that connects to the pipe 21 and connects to the inside of the mop handle 1. The pull rod 4 passes through the mop handle 1 and the mop head housing 2 and extends out through the movable opening 11 and the through hole 22.

[0042] The mop head housing 2 is provided with a connecting part 23 for mounting the traction component 6. The traction component 6 is rotatably mounted on the connecting part 23, and the one-way bearing 7 is fixed on the traction component 6. The two ends of the one-way bearing 7 extend with drive rods 71. The drive rods 71 ​​adopt a non-circular structure and are inserted into the cleaning drum 5.

[0043] The traction component 6 has a rotating hole 61 that is coaxial with the cleaning drum 5, and a traction hole 62 that is coaxial with but offset from the rotating hole 61. That is, the rotating hole 61 and the traction hole 62 are coaxial but offset from each other. The pull rod 4 has a main section 41 and a traction shaft 42 that protrudes from the main section 41. The traction shaft 42 is inserted into the traction hole 62 for installation.

[0044] To facilitate the installation of the pull rod 4 and the traction component 6, and to prevent the pull rod 4 and the traction component 6 from rotating and disengaging, the traction component 6 is provided with an installation port 63, which connects to the traction hole 62. The traction shaft 42 is provided with a limiting part 43 that can pass through the installation port 63. When the traction shaft 42 and the pull rod 4 are installed on the mop, the operating handle 3 drives the pull belt to pull the traction component 6 to rotate around the rotating hole 61. The traction component 6 and the pull rod 4 rotate around the axis of the traction shaft 42. Since the rotation angle is limited, it can be set so that the limiting part 43 and the installation port 63 will not be aligned during the rotation, so that the traction machine is located between the main section 41 and the limiting part 43.

[0045] To facilitate the installation or replacement of the cleaning drum 5, the mop head housing 2 includes a main frame 2a and side frames 2b that are plugged into both sides of the main frame 2a. The side frames 2b and the main frame 2a can be interference-fitted or installed by means of accessories such as pins 2c. In this embodiment, there are two cleaning drums 5. One cleaning drum 5 is located between the side frame 2b and the connecting part 23, and the other cleaning drum 5 is located between the side frame 2b and the traction member 6. That is, the cleaning drums 5 are rotatably arranged at both ends of the rotation axis of the traction member 6.

[0046] like Figure 2 , Figure 3 and Figure 6 As shown, the cleaning drum 5 includes a load shell 5a, a first rotating connector 5b, a second rotating connector 5c, and a cleaning layer 5d. The load shell 5a adopts a tubular structure, while the first rotating connector 5b and the second rotating connector 5c are respectively inserted and installed at both ends of the load shell 5a. The cleaning layer 5d is wrapped around the outer ring of the load shell 5a. The drive rods 71 ​​at both ends of the one-way bearing 7 are inserted into the first rotating connector 5b and the second rotating connector 5c.

[0047] The cleaning layer 5d can be glued to the load shell 5a; or the surface of the load shell 5a has a recess 5a1, in which a clip 5e can be detachably installed. The clip 5e is installed to the load shell 5a by means of snap-fit ​​or screw connection. The clip 5e clamps and fixes the cleaning layer 5d between the clip 5e and the load shell 5a. The cleaning layer 5d is made of cotton or mop, and the mop is made of fiberglass cloth or other materials.

[0048] To facilitate cleaning the water and adhesive on the cleaning layer 5d of the cleaning drum 5, a squeegee limiter 8 and a brush 9 are installed on the main frame 2a of the mop head housing 2. The brush 9 contacts the cleaning layer 5d, and the squeegee limiter 8 squeezes the cleaning layer 5d and leaves a gap between it and the load housing 5a. The main frame 2a is provided with a mounting groove 24 for mounting the brush 9.

[0049] The main frame 2a has side parts 25 on both sides. Both the side parts 25 and the connecting part 23 have connecting holes 26. The wiper limiter 8 is inserted into the connecting hole 26. The side frame 2b has intersecting insertion parts 2b1 and side wings 2b2. The side frame 2b is connected to the main frame 2a through the insertion parts 2b1. The pin 2c is inserted into the main frame 2a and the insertion parts 2b1 to limit the side frame 2b from the main frame 2a. At the same time, the side wings 2b2 of the two side frames 2b can limit the wiper limiter 8 from sliding out of the connecting hole 26.

[0050] The squeegee limiter 8 and the load shell 5a of the cleaning drum 5 exert a squeezing force on the cleaning layer 5d. The presence of this squeezing force allows the water on the cleaning layer 5d to be cleaned, and at the same time, it also prevents the cleaning drum 5 from rotating when the mop is mopping, and does not drive the pull rod 4 and the operating handle 3 to move. Preferably, the squeegee limiter 8 can limit the rotation of the cleaning drum 5 through friction or damping.

[0051] In other embodiments, the operating handle 3 and the mop handle 1 may be provided with torsion springs, which exert a downward flipping force on the operating handle 3 and at the same time limit the rotation of the cleaning drum 5 when the mop is mopping the floor.

[0052] To ensure the rationality of the position distribution, the wiper limiter 8 is located between the brush 9 and the pull rod 4, and the pull rod 4 will not pass the wiper limiter 8 when it drives the traction component 6 to rotate.
