Description

Technical Field

[0001] The present invention relates to the technical field of cleaning devices, and more particularly to a water removal device, in particular a water removal device for a mop. Background Art

[0002] Mops have long been widely used as a floor scrubbing tool. With the advancement of urbanization, changes in living environments, and improvements in living standards, the use of floor scrubbing tools is increasing, and users' requirements for their functionality and quality are also rising. To meet this demand, a wide variety of floor scrubbing tools have been introduced to the market over the years. However, traditional mops (e.g., mops with a long handle and a bundle of cloth strips or fiber strings attached to one end) still have a place in the floor scrubbing tool market and are favored by many users due to their adaptability, flexible mopping, strong cleaning ability, ease of cleaning, and relatively long service life.

[0003] However, traditional mops also have a significant drawback: after washing the mop, it's usually necessary to manually wring out excess water to a certain level to get it wet enough for mopping. This requires considerable effort, is inconvenient, and makes using a traditional mop cumbersome. Furthermore, when the mop is washed and wrung out for subsequent use, the cleaning is often incomplete, and the remaining water carried by the mop can stain the user's hands. The current market for floor scrubbing tools has yet to find a satisfactory solution to this problem. While some related products exist, such as devices that use a push plate to squeeze the mop head to remove water, these have not achieved satisfactory water removal results. Summary of the Invention

[0004] The purpose of the present invention is to solve at least one aspect of the above-mentioned problems and defects in the prior art and / or other technical problems.

[0005] The present invention provides a water removal device, which includes a shell, a rotating disk and a driving device arranged in the shell, a first annular member arranged on the shell or integrated with the shell, and a second annular member located between the rotating disk and the first annular member, wherein the rotating disk can rotate under the action of the driving device; the water removal device also includes a plurality of wires and a guide rail, wherein each wire is connected to the rotating disk with its first end, extends from the rotating disk through the second annular member, then winds around the first annular member and passes out from it, and extends to the second annular member and is connected to the second annular member with the second end of the wire, wherein the plurality of wires are in a tensioned state; the second annular member is slidably connected to the guide rail and can move between the rotating disk and the first annular member under the guidance of the guide rail.

[0006] In the above scheme, by providing a rotating disk (also known as a wire drum), a first annular member (also known as a wire passing ring) and a second annular member (also known as a wire control ring) that can slide along the guide rail, and a plurality of tensioned wires wound around the rotating disk, the first annular member and the second annular member, it is achieved that in the process of the rotating disk rotating and pulling the wire control ring away from the rotating disk to slide, the plurality of wires are spirally wound on the object to be dehydrated, such as a mop. Within a limited space, with a minimalist and ingenious structural design, the object to be dehydrated can be evenly wrapped and squeezed by the orderly and dense spiral winding of the plurality of wires. The process is similar to the process of manual twisting, thereby ensuring reliable and uniform dehydration of the mop. In addition, the entire structure is simple, low-cost and easy to implement, and is convenient for the operator to operate, avoiding the troublesome process of manually twisting the mop.

[0007] According to one example, the driving device includes a motor, which is coupled to the rotating disk to drive the rotating disk to rotate forward and reverse.

[0008] This exemplary solution leverages the power of a motor to uniformly and forcefully twist and squeeze the mop head, which is wrapped in multiple threads, until no more space is left, thereby extracting excess water. This method saves manpower, facilitates operation, and saves time; for example, the entire water removal and return process takes only seconds.

[0009] According to an example, the first annular member and the second annular member are concentrically arranged, and the outer diameter of the second annular member is larger than the inner diameter of the first annular member. The second annular member can move to abut against the first annular member under the guidance of the guide rail.

[0010] In this exemplary solution, the first annular member serves as the end point of the travel of the second annular member, preventing the second annular member from rising any further. The torque transmitted by the motor through the transmission device forces the several wires to continue winding. Since the wire length provided by the second annular member when it rises is no longer available, the spiral wire can only shrink and wind inward, making the space where the mop head is wrapped smaller and smaller, and the balanced extrusion force on various parts of the mop head becomes stronger and stronger, thereby achieving a better extrusion and water removal effect.

[0011] According to one example, the rotating disk is disposed at the bottom of the housing opposite the inlet end of the housing, and the second annular member is disposed adjacent to the rotating disk. This structure allows the lowermost portion of the string or cloth strip on the mop head to be fully wrapped and squeezed, thereby ensuring that all parts of the mop head are effectively dewatered.

[0012] According to an example, the first annular member is disposed at the inlet end of the housing. This exemplary solution enables the winding height of the plurality of lines on the dehydrated object to extend from the bottom of the housing to the inlet end of the housing, making full use of the space inside the housing.

[0013] According to an example, the dewatering device further comprises a support rod disposed in the housing and adapted to support the dewatered object. The support rod facilitates placement of the dewatered object and winding of the plurality of wires around the dewatered object, thereby achieving a better dewatering effect.

[0014] According to one embodiment, the support rod is disposed on the rotating disk and extends from the rotating disk to a position adjacent to the first annular member. This structure ensures that the top portion of a string, cloth strip, or the like on a mop head resting on the support rod can also be completely wrapped and wrapped by the spiral thread, thereby evenly squeezing and removing water, thereby effectively removing water from all parts of the mop head.

[0015] According to an example, the rotating disk is provided with a plurality of third holes, the number of which is the same as the number of the plurality of wires, for respectively connecting the first ends of the plurality of wires, and the plurality of third holes are evenly arranged along the circumference of the rotating disk.

[0016] With this exemplary structure, the multiple wires are evenly arranged along the circumference of the rotating disk. As the rotating disk rotates, the multiple wires are spirally wound in an orderly and dense manner, evenly wrapping and squeezing the dewatered material, achieving a more uniform and effective water squeezing effect. Furthermore, in this exemplary structure, the first end of the wire can be passed through the third hole and tied into a knot to connect the wire to the rotating disk, providing a simple and reliable way to connect the wire to the rotating disk.

[0017] According to an example, the first annular member is provided with a plurality of first holes, the number of which is the same as the number of the plurality of wires, for the plurality of wires to be wound around respectively, and the plurality of first holes are evenly arranged along the circumference of the first annular member.

[0018] According to one example, two rows of second holes aligned in the radial direction are provided on the second annular member, wherein the number of the plurality of second holes in each row is the same as the number of the plurality of lines and are evenly arranged along the circumference of the second annular member, and the plurality of second holes on the radial inner side are for the plurality of lines to pass through respectively, and the plurality of second holes on the radial outer side are used to respectively connect the second ends of the plurality of lines.

[0019] According to an example, the plurality of lines are tensioned by the gravity of the second annular member. In this exemplary solution, the tensioning of the lines is achieved with a simple structure and guarantees a tight winding of the dewatered object and a smooth release and return of the line control ring after dewatering.

[0020] According to one example, the plurality of wires are tensioned by the weight of the second annular member and an additional force applied to the second annular member. This exemplary solution can apply additional force as needed to more effectively ensure a tight wrapping of the dewatered object and a smooth release and return of the wire control ring after dewatering.

[0021] According to one example, the water removal device further comprises a counterweight disposed on the second annular member to provide the additional force. According to another example, the water removal device further comprises a plurality of first pendants respectively disposed at the first ends of the plurality of lines, and / or a plurality of second pendants respectively disposed at the second ends of the plurality of lines to provide the additional force.

[0022] According to an example, the water removal device further includes a spring, and the spring is configured to bias the second annular member in a direction of tensioning the plurality of wires to provide the additional force.

[0023] According to one example, the housing includes a first housing and a second housing located substantially below the first housing. The first and second housings define separate first and second accommodation spaces. The rotating disk, the first annular member, the second annular member, the plurality of wires, and the guide rail are disposed in the first accommodation space, and the drive device is disposed in the second accommodation space. This exemplary structure isolates the drive device from water extruded from the first accommodation space, thereby protecting the drive device, particularly the electric drive device, from water erosion.

[0024] According to one example, the driving device includes a transmission device arranged in the second accommodating space and a drive shaft connected to the transmission device and extending into the first accommodating space to be fixed to the rotating disk, wherein the drive shaft is rotatably arranged in a bearing seat fixed to the bottom of the first shell.

[0025] According to one example, the rotating disk is configured to cover the bearing seat above the bearing seat. This exemplary structure can effectively prevent squeezed water from entering the bearing seat and the second accommodation space (also called the lower accommodation space), ensuring that the driving device in the lower accommodation space, such as the motor and its control board, is kept dry.

[0026] According to an example, a protrusion protruding toward the rotating disk is formed on the bottom of the first shell, and the bearing seat is fixed to the protrusion.

[0027] The setting of the protrusion in this example allows the squeezed water to be guided by the protrusion into the recesses on both sides of the protrusion, and the bearing seat is set on the protrusion, so water is not easy to contact the bearing seat, which better ensures the dryness of the lower accommodating space.

[0028] According to an example, the upper surface of the rotating disk is inclined radially outward toward the bottom of the first shell. This structure can facilitate the water to be guided into the protrusion and the recesses on both sides thereof, thereby facilitating the drainage of the water.

[0029] According to one example, the water removal device further includes two actuators extending from the shell, one of which is used to operate the drive device to start the water removal process of the water removal device, and the other is used to operate the drive device to start the return process of the water removal device.

[0030] According to one example, during the dewatering process, the rotating disk rotates in a first direction under the action of a driving device, pulling the plurality of wires so that the second annular member moves away from the rotating disk toward the first annular member, and the wires between the rotating disk and the second annular member are wound around the object to be dewatered.

[0031] According to one example, during the return process, the rotating disk rotates in a second direction opposite to the first direction under the action of a driving device, so that the several lines are loosened, and the second annular member moves away from the first annular member toward the rotating disk to return.

[0032] According to one example, the plurality of threads are made of ultra-high molecular weight polyethylene fibers, which provide the threads with excellent self-lubricating and wear-resistant properties, and remain soft and tough even when exposed to water.

[0033] According to one example, the object to be dehydrated is a mop.

[0034] According to another aspect of the present invention, a cleaning device is provided, comprising the dewatering device described in the above examples and a cleaning container, wherein the cleaning container is attached to or integrally formed with the dewatering device. The cleaning device combines the advantages of the dewatering device described herein with greater convenience. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The features and advantages of the embodiments of the present invention will be more readily understood with reference to the detailed description and accompanying drawings below, in which:

[0036] Figure 1 A schematic cross-sectional view of a water removal device according to an exemplary embodiment of the present invention is shown; and

[0037] Figure 2 Shown Figure 1 The cross-sectional schematic diagram of the water removal device shown in another position, wherein the guide rail is shown and the various lines are not shown to simplify the structure. DETAILED DESCRIPTION

[0038] The following examples and accompanying drawings further illustrate the technical solution of the present invention. The following description of the embodiments of the present invention with reference to the accompanying drawings is intended to explain the overall concept of the present invention and should not be construed as limiting the present invention.

[0039] In addition, in the following detailed description, for ease of explanation, numerous specific details are set forth to provide a comprehensive understanding of the embodiments. However, it is apparent that one or more embodiments can be practiced without these specific details. Furthermore, to simplify the drawings, well-known structures and devices are not shown in the illustrated form.

[0040] As an exemplary embodiment of the present invention, a water removal device 100 is provided. The device can be used to remove water from a dewatered object, such as a mop. It should be noted that, while the dewatering device for a mop is described herein as an example, those skilled in the art will appreciate that the dewatering device employing the concepts of the present invention is not limited to dewatering mops. The device can also be used to remove water from other cleaning products, such as rags, or other suitable dewatered objects.

[0041] In this exemplary embodiment, the housing 1 of the water removal device 100 is composed of a substantially cylindrical first housing 11 (also referred to as an upper housing) and a substantially cylindrical second housing 12 (also referred to as a lower housing). Figure 1 As shown, the first shell 11 and the second shell 12 are concentrically arranged, wherein the first shell 11 is partially sleeved in the second shell 12, and the two are connected by Figure 1 、 2 The connecting support 13 and the connecting bolt 14 shown in FIG are fixed together. Figure 1 、 2 As can be seen, the first housing 11 and the second housing 12 define a first accommodating space (also referred to as an upper accommodating space) and a second accommodating space (also referred to as a lower accommodating space), respectively, and the upper accommodating space and the lower accommodating space are separated by the bottom of the first housing 11. It will be understood by those skilled in the art that the structure of the housing of the water removal device of the present invention is not limited to the structure described in the specific embodiments and shown in the drawings.

[0042] like Figure 1 、 2 As shown, the dewatering device 100 also includes a rotating disk 2 arranged in the housing 1 and a driving device for rotating the rotating disk 2. The driving device in the illustrated example adopts the structure of a motor 7 and a transmission device 8 (such as a reducer). Those skilled in the art will understand that the driving device for the rotating disk 2 is not limited to an electric method, and a purely mechanical driving device, such as a rack-and-pinion structure, can also be adopted. However, it should be pointed out that the use of a motor drive method instead of manpower can perform a powerful twisting and squeezing on the dewatered object, and more efficiently squeeze out the excess water therein. This method saves manpower and is convenient to operate; it also saves time. For example, it only takes a few seconds to complete the entire dewatering and returning process.

[0043] like Figure 1As shown, the output shaft of the transmission device 8 is connected to the drive shaft 10 through a coupling 15. A bearing seat 101 is fixed to the bottom of the first housing 11 through a nut 102. The drive shaft 10 is rotatably disposed in the bearing seat 101 through a bearing 103 and extends into the first accommodation space defined by the first housing 11. The rotating disk 2 is fixed to the drive shaft 10 to rotate together with the drive shaft 10. Figure 1 As shown, the drive shaft 10 can also be connected to the support rod 9 provided on the rotating disk 2, thereby also driving the support rod 9 to rotate, and the support rod is suitable for supporting the mop. The support rod 9 facilitates the placement of the water to be removed and the winding of the multiple lines on the water to be removed, which is conducive to achieving a better water removal effect.

[0044] The water removal device 100 further includes a first annular member 3 (also called a wire passing ring) provided at the inlet end of the housing 1, a second annular member 4 (also called a wire control ring) located between the rotating disk 2 and the first annular member 3, and a guide rail 6 (also called a wire control ring). Figure 2 ) and a plurality of wires 5 wound between the rotating disk 2, the first annular member 3 and the second annular member 4. The second annular member 4 is provided with a hole 61 (in Figure 2 ), the second annular member 4 is sleeved on the guide rail 6 through the hole 61 and is thereby slidably connected to the guide rail 6. Two guide rails 6 may be symmetrically provided, and correspondingly, two holes 61 are provided on the second annular member 4. Those skilled in the art will appreciate that a plurality of guide rails 6 may also be provided, which may be evenly distributed in the circumferential direction relative to the second annular member 4. As an example, one end of the guide rail 6 is fixed to the bottom of the first shell 11, and the other end is fixed to the first annular member 3. Although the above description and the accompanying drawings are all illustrated by taking the first annular member 3 as an example of being connected to the shell 1, those skilled in the art will appreciate that the first annular member 3 may also be formed as an integral part with the shell 1, for example, a flange protruding radially inward from the inlet end of the shell 1 is used as the first annular member.

[0045] like Figure 1 As shown, the rotating disk 2 is provided with a plurality of third holes 21, the same number as the plurality of wires 5, for respectively connecting the first ends of the plurality of wires 5. The plurality of third holes 21 are evenly arranged along the circumference of the rotating disk 2. The wires 5 are connected to the rotating disk 2 by passing the first ends of the wires 5 through the third holes 21 and tying a knot or providing a first pendant 51. It will be understood by those skilled in the art that the third holes 21 may not be provided, and the plurality of wires 5 may be connected to the rotating disk 2 in other ways.

[0046] The second ring member 4 is provided with two rows of second holes 41 aligned in the radial direction, wherein the number of the second holes 41 in each row is the same as the number of the lines 5 and is evenly arranged along the circumference of the second ring member 4, and as shown in FIG. Figure 1As shown, the plurality of second holes 41 on the radially inner side are respectively provided for the plurality of wires 5 to pass through, and the plurality of second holes 41 on the radially outer side are respectively provided for connecting the second ends of the plurality of wires 5. The first annular member 3, i.e., the wire passing ring, is provided with a plurality of first holes 31, the same number as the plurality of wires 5, for the plurality of wires 5 to be respectively wound therethrough. The plurality of first holes 31 are evenly arranged along the circumference of the first annular member 3.

[0047] like Figure 1 As shown, the first end of each wire 5 is connected to the rotating disk 2 through the obstruction of the first pendant 51, passes through the third hole 21 on the rotating disk 2 and continues to extend through the second hole 41 on the radial inner side of the second ring member 4, and then continues to extend to the first ring member 3, passes from the inner edge of the first ring member 3, and then reverses and enters the first hole 31 of the first ring member 3, and passes through the first hole 31, and continues to extend to the second hole 41 on the radial outer side of the second ring member 4, and is connected to the second ring member 4 in a way that the second end of the wire is provided with a second pendant 52. Figure 1 In the example shown, the second annular member 4 and the first annular member 3 are concentrically arranged. The first holes 31 on the first annular member 3 and the second holes 41 on the radially outer side of the second annular member 4 are aligned in the axial direction of the housing 1, that is, these holes have the same radial radius, which is achieved as shown in FIG. Figure 1 The vertical arrangement of the lines 5 shown reduces the resistance of the lines 5. The second holes 41 on the radial inner side of the second annular member 4 are aligned with the inner edge of the first annular member 3 in the axial direction of the housing 1, which is also conducive to achieving the following Figure 1 The vertical arrangement of the wire 5 is shown and reduces the resistance of the wire 5.

[0048] Those skilled in the art will understand that although the structures of the first annular member 3, the second annular member 4 and the rotating disk 2 and the winding or threading order of the plurality of wires 5 on these structures are described above in an exemplary manner, this is only an exemplary specific structure, the threading order therein is changeable, and the structures of the first annular member 3, the second annular member 4 and the rotating disk 2 can also be changed.

[0049] In the exemplary structure of the water removal device, the plurality of wires 5 are in a tensioned state to ensure the tight winding of the water-removed object and the smooth release and return of the wire control ring after the water is removed. The tension of the plurality of wires 5 is achieved, for example, by the gravity of the second ring member 4. Figure 1As shown, the second ring member 4, or the control loop, is suspended under the combined effects of its own weight and the tension of the wires. Each wire is taut, and all the wires together form a cylindrical arrangement, with the control loop in a horizontal position. It should be noted that using the weight of the second ring member 4, or the control loop, to tension the wires 5 and return the control loop (the return process will be described below) is merely an example. Other methods can also be employed, such as applying an additional force in addition to the weight of the second ring member 4 to achieve tension and return. This additional force can be achieved, for example, by providing a counterweight (not shown) on the second ring member 4 (e.g., on the lower surface of the second ring member 4). This additional force can also be achieved by providing a first pendant 51 on the first end of the wire 5 and / or a second pendant 52 on the second end of the wire 5. The first pendant 51 and / or the second pendant 52 can be made of materials such as stainless steel or cast iron, with their weight taut the wire 5. This additional force can also be achieved, for example, by providing a spring. The spring is, for example, disposed between the second annular member 4, i.e., the wire control ring, and the bottom of the first housing 11, and is configured to bias (pull downward in the figure) the second annular member 4 in the direction of tensioning the plurality of wires 5 to provide additional force. In the example of applying additional force, the tensioning of the plurality of wires 5 and the return of the wire control ring are achieved by the gravity of the second annular member 4 and the additional force applied to the second annular member 4. It should be noted that the above-mentioned exemplary methods for ensuring the tensioning of the wires 5 can be used individually or in combination with two or more of them.

[0050] like Figure 1 、 2 As shown, the rotating disk 2, the first annular member 3, the second annular member 4, the plurality of wires 5 and the guide rail 6 are arranged in the first accommodation space. Under the drive of a driving device such as a motor 7, the rotating disk 2 rotates, pulling the plurality of wires 5 uniformly distributed in the circumferential direction thereon. These wires 5 slide in the second hole 41 of the second annular member 4 and the first hole 31 of the first annular member 3, respectively, and pull the second annular member 4 through their second ends, so that the second annular member 4 is guided away from the rotating disk 2 toward the first annular member 3 (at the bottom of the first annular member 3) under the guidance of the guide rail 6. Figure 1 The rotating disk 2 and the second ring 4 move upward. Simultaneously, the threads 5 between the rotating disk 2 and the second ring 4 are wrapped around the lowermost portion of the string or cloth strip on the mop head. As the rotating disk 2 continues to rotate, pulling the threads 5, the second ring 4 continues to rise, gradually increasing the length of the threads 5 between the rotating disk 2 and the second ring 4. Under the action of the rotating disk's rotation, the threads form an ascending spiral. The threads gradually and evenly wrap around the mop head from bottom to top, squeezing and removing water.

[0051] In a preferred embodiment of the present invention, Figure 1As shown, the second ring member 4 is concentrically arranged with the first ring member 3, and the outer diameter of the second ring member 4 is larger than the inner diameter of the first ring member 3. Thus, the second ring member 4 can move to abut against the first ring member 3 under the guidance of the guide rail 6 and then stop under the obstruction of the first ring member 3. Because the first ring member 3 can block the second ring member 4 and stop it, the torque transmitted by the motor 7 through the transmission device forces the wire 5 to continue winding. Since the wire length provided by the second ring member 4 when it rises is no longer available, the spiral wire 5 can only shrink inward and wind, resulting in a smaller and more balanced torsional extrusion force on the mop head. This achieves a better extrusion and water removal effect. In this embodiment, the outer diameter of the second ring member 4 is larger than the inner diameter of the first ring member 3, and the first ring member 3 serves as the end point of the travel of the second ring member 4. This can achieve the above functions while reducing the size of the housing and the entire water removal device, and reducing the deflection and sliding resistance of the wire, thereby reducing the power requirement of the water removal device. However, those skilled in the art will appreciate that the embodiment in which the outer diameter of the second annular member 4 is greater than the inner diameter of the first annular member 3 so that the first annular member forms the end point of the travel of the second annular member is merely a preferred specific structure, and the relative dimensions between the two are not limited thereto. Furthermore, the manner of setting the end point of the travel of the second annular member 4, i.e., the wire control ring, is not limited thereto. For example, a stop member for the second annular member 4 may also be provided on the inner wall of the housing 1.

[0052] Furthermore, the first annular member 3 can be disposed at the inlet end of the housing 1, and the support rod 9 extends substantially from the rotating disk 2 to the inlet end and is preferably slightly lower than the first annular member 3. This structure ensures that the top of the mop head resting on the support rod 9 can also be completely wrapped and wrapped by the overall spiral wire 5, thereby evenly squeezing and removing water. It should be noted that although the support rod is described herein and its specific installation structure is shown in the embodiments of the accompanying drawings, and the solution of the present invention has many advantages due to this arrangement of the support rod, those skilled in the art will understand that the design of the present invention does not necessarily include this support rod (for example, the mop can be manually suspended by the operator), and its structure is not limited to the structure shown in the drawings.

[0053] like Figure 1 As shown, the rotating disk 2 is disposed at the bottom of the housing 1 opposite the aforementioned inlet end, and the second annular member 4 is disposed adjacent to the rotating disk 2. This structure allows the lowermost portion of the string or cloth strip on the mop head to be fully wrapped and squeezed, thereby ensuring that all parts of the mop head are effectively dewatered.

[0054] like Figure 1 As shown, the drive device (especially the electric drive device including the motor 7 and its reducer) is arranged in the second accommodation space, that is, the lower accommodation space. Figure 1It can be seen that the rotating disk 2 is configured to cover the bearing seat 101 above the bearing seat 101. This structure can effectively prevent the squeezed water from entering the bearing seat and the lower accommodating space, thereby ensuring the dryness of the motor 7 and its control board in the lower accommodating space.

[0055] Preferably, from Figure 1 、 2 It can also be seen that the bottom of the first housing 11 is formed with a protrusion 111 protruding toward the rotating disk 2, and the bearing seat 101 is fixed to the protrusion 111. The arrangement of the protrusion 111 allows the squeezed water to be guided by the protrusion 111 into the recesses on both sides of the protrusion. Since the bearing seat 101 is arranged on the protrusion, water is not likely to come into contact with the bearing seat, thus better ensuring the dryness of the lower accommodation space. Figure 1 、 2 It can also be seen that the upper surface of the rotating disk 2 is inclined radially outward toward the bottom of the first housing 11. This structure can facilitate the guidance of water into the protrusion 111 and the recesses on both sides thereof. For example, a drain pipe can be provided in the recess to drain the water.

[0056] The motor 7 of this dewatering device 100 can realize the forward and reverse rotation of rotating disk 2 via transmission device 8 and drive shaft 10. Accordingly, the dewatering device may include two actuating members (not shown) extending from housing 1, such as two foot pedals. A first actuating member of the two actuating members can be used for actuating the motor of the drive device to start the dewatering process of the dewatering device, and a second actuating member of the two actuating members can be used for operating the motor to start the return process of the dewatering device.

[0057] After a large number of experiments to compare the effects and performance of various materials, the inventors of the present invention selected ultra-high molecular weight polyethylene as the material for several wires 5 of the water removal device 100. This material makes these wires have excellent self-lubricating and wear-resistant properties, and they can still remain soft and tough after contacting water. At the same time, they have high specific strength (its specific strength is, for example, more than ten times that of steel wire with the same cross-section), which can effectively prevent breakage. Preferably, both the wire control ring and the wire passing ring can be made of self-lubricating materials to ensure the smooth operation of the wire 5 and reduce wear. It should be pointed out that these materials for the wires, wire control rings and wire passing rings are existing materials. The improvement of the preferred embodiment of the present invention lies in the process of selecting suitable and high-performance materials for the wires, wire control rings or wire passing rings, rather than in these materials themselves.

[0058] The following describes a specific example of the process of the water removal device 100 removing water from the mop and the subsequent return process.

[0059] The mop head containing excess water is placed on the support rod 9. Due to the moisture in the mop head, a whole bundle of fiber strings (or fabric strips, non-woven fabrics, etc.) on the mop head will stretch and droop, thereby forming a relatively neatly arranged bundle.

[0060] When the first actuating member is actuated, for example, when the foot switch is stepped on, the motor 7 is started, and the rotating disk 2 is driven by the motor 7 to move in a first direction (for example, Figure 1 The rotating disk 2 is rotated in the counterclockwise direction (as viewed from above), and several wires 5 evenly distributed in the circumferential direction are pulled. These wires 5 slide in the second holes 41 of the second annular member 4 and the first holes 31 of the first annular member 3, respectively, and the second annular member 4 is pulled by its second end, so that the second annular member 4 is guided away from the rotating disk 2 toward the first annular member 3 (at Figure 1 At the same time, the plurality of lines 5 between the rotating disk 2 and the second annular member 4 are wound around the lowermost portion of the string or cloth strip wrapped around the mop head.

[0061] As the rotating disk 2 continues to rotate, pulling the plurality of wires 5, the second annular member 4 (the wire control ring) continues to rise, increasing the length of the plurality of wires 5 between the rotating disk 2 and the second annular member 4. This portion of the wires 5 forms an ascending spiral, gradually and evenly wrapping and squeezing the mop head from bottom to top to remove water. As described above, because the plurality of wires 5 are evenly distributed in the circumferential direction, the string or cloth strips on the mop head are evenly wrapped and squeezed, a process similar to that of hand twisting, ensuring reliable and uniform water removal from the mop.

[0062] When the second ring member 4, i.e., the control line ring, is pulled up to the highest point (e.g., blocked by the first ring member 3) and cannot move upward any further, since the top of the support rod 9 is slightly lower than the first ring member 3, the top of the string or cloth strip of the mop head is also located at this position, so the entire mop head has been completely wrapped and evenly squeezed to remove water by the spiral line 5. At this time, the torque transmitted by the motor 7 through the transmission device forces the line to continue to be wound. Since the line length provided by the control line ring when it rises is no longer available, the spiral line 5 can only shrink and wrap inward, making the space where the mop head is wrapped smaller and smaller, and the balanced torsional squeezing force received by various parts of the mop head is also stronger and stronger, thereby achieving a better / user-desired squeezing and dewatering effect. The squeezed / squeezed water is discharged through a drain pipe (not shown) provided on the first housing 11.

[0063] In this dewatering process, the second annular member 4, i.e., the line control ring, controls several lines 5 to be wound with a smaller helix angle, and keeps substantially the same helix angle throughout the entire process, so as to realize the dense and uniform winding and wrapping of the dewatered object from beginning to end. Further, the smaller helix angle can make the tension of the line produce a larger force component in the circumferential direction, thereby bringing into play an optimal squeezing effect and reaching a faster and more effective squeezing effect. Taking the dewatered object as an example, the dewatering device of the present invention, compared with a hand-twisted mop, not only greatly reduces time (for example, only requires a few seconds), but also dewaters more cleanly and more evenly.

[0064] In the exemplary water removal device of the present invention, since the wire is tensioned at any position, it ensures tight winding of the water-removed object and smooth release and return of the wire control ring after water removal.

[0065] When the mop is finished removing water and needs to be taken out, the second actuating member is actuated, and the motor 7 drives the rotating disk 2 to rotate in a second direction opposite to the first direction, loosening the plurality of wires 5. The second annular member 4 moves away from the first annular member 3 toward the rotating disk 2 under the action of its own weight as described above (or under the combined action of its own weight and the additional force described above) to return to its rest position.

[0066] The present invention also provides a cleaning device that combines a dewatering device 100 with a cleaning container (not shown). For example, the cleaning container is attached to the dewatering device or is integrally formed with the dewatering device. After the dewatered object, such as a mop, is cleaned in the cleaning container, it is directly placed in the dewatering device 100 for dewatering. This cleaning device combines the various advantages of the dewatering device described in the present invention and is more convenient to use.

[0067] It should be emphasized again that the combination of various features in the embodiments described herein is only used as a preferred example to better illustrate the concept of the present invention, and does not mean that the implementation of the technical solution of the present invention must have some or certain of these features.

[0068] Although some examples of the present general inventive concept have been described herein, those skilled in the art will appreciate that changes may be made to these embodiments without departing from the principles and spirit of the present general inventive concept, the scope of which is defined by the claims and their equivalents.
