Description

A flat mop squeezing device and a hands-free flat mop Technical Field

[0001] This utility model belongs to the field of cleaning tool technology, and in particular relates to a flat mop squeezing device and a hands-free flat mop. Background Technology

[0002] Chinese patent CN217610928U discloses a "Wringer and Mop," which includes a main body with a container section connected to a pump head. A shaping frame is mounted on the main body and is slidably installed thereon. The pump head is squeezed by sliding the shaping frame, which has a perforation hole. Detergent is added to the container section, and after being pumped out, it passes through the perforation hole to create a perforated pattern, squeezing the detergent onto the floor in a perforated form. This eliminates the need for additional cleaning agent spraying, improving cleaning efficiency. However, in this structure, the mop pulling and cleaning with detergent are two relatively independent steps; the detergent cleaning process is not integrated into the mop pulling process, leaving the cleaning effect of the mop needing further improvement. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a flat mop squeezing device and a hands-free flat mop, which combines the pull-out cleaning of the flat mop and the deep cleaning of the cleaning body into an integrated structure, making it convenient to clean the flat mop.

[0008] The cavity is used to store the cleaning fluid;

[0009] The transfer section can contact the cleaning body and the flat mop respectively, and is used to transfer the cleaning body in the cavity to the wiping material of the flat mop.

[0010] Furthermore, the transfer unit and the wringer are relatively stationary; or, the transfer unit may be movable relative to the flat mop, the movement including rotation and / or movement.

[0011] Furthermore, the transfer unit has an uneven structure for acquiring the clean body.

[0012] Furthermore, the transfer unit is located in the transmission unit, which has at least an operating state and a waiting state. In the operating state, at least a portion of the transmission unit contacts or tends to contact the wiping material of the flat mop to transfer the cleaning material to the wiping material. In the waiting state, the transmission unit stops transferring the cleaning material to the wiping material.

[0013] Furthermore, the transfer unit is located in the transfer unit, which has at least an active state and a locked state. In the active state, at least a portion of the transfer unit moves to transport the cleaning material in the cavity to the wiping material; in the locked state, the transfer unit stops moving so that the cleaning material in the cavity stops being transported to the wiping material.

[0014] Furthermore, the transfer section is a mesh that at least partially covers the periphery of the clean body.

[0025] Furthermore, the relative position of at least a portion of the transmission unit and the dewatering rack is changed; or, the relative position of at least a portion of the cavity and at least a portion of the transmission unit is changed, so that the transmission unit switches between an operating state and a waiting state.

[0026] Furthermore, the transfer unit is a transfer roller with transfer teeth distributed on its outer wall. It rotates around the shaft to transfer the cleaning body in the cavity to the wiping object.

[0027] or,

[0028] The transfer unit is a transfer ball that rolls inside a circular hole. Its outer wall has grooves, and its rolling motion transfers the cleaning material in the cavity to the wiping material.

The transfer roller can rotate under the drive of a flat mop, and a crank is eccentrically connected to the transfer roller. The scraper is connected to a movable groove into which the crank extends. When the transfer roller rotates relative to the wringing frame, the crank drives the scraper to move relative to the cleaning body through the movable groove, so that the scraper scrapes the cleaning body and transfers it to the wiping material.

[0031] Furthermore, the transmission unit is movably connected to the desqueezing rack, and at least part of it is movable relative to the desqueezing rack to switch between a working state and a waiting state.

[0032] or,

[0036] or,

[0037] At least a portion of the cavity is movable relative to the wringer, thereby changing the relative position of at least a portion of the transmission unit with respect to the cleaning body, in order to switch between a working state and a waiting state.

[0038] Furthermore, the cavity is movably mounted on the dewatering frame, and the transmission unit is located on the side of the cavity facing the dewatering channel. The cavity can move relative to the dewatering frame so that the transmission unit can switch between a working state and a waiting state.

[0039] Furthermore, it also includes a drive assembly, at least a portion of which translates and / or rotates to move the cavity relative to the squeezing frame, such that the cavity moves closer to or further away from the squeezing channel.

An external force is applied to drive the shifting member to move relative to the wringer in the shifting groove, and the cavity extends out of or retracts from the wringer.

[0041] Furthermore, it also includes a blocking unit, wherein the squeezing member and the transfer unit are located on the same side of the squeezing channel, and the blocking unit can be moved between the squeezing member and the transfer unit, or the blocking unit can be moved between the wiping material and the transfer unit, or the blocking unit can be moved between the cleaning body and the transfer unit, so as to isolate the transfer unit and the wiping material.

[0042] Furthermore, it also includes a locking unit, which is used to drive the transfer unit to switch between an active state and a locked state.

[0043] Furthermore, the locking unit includes a driving part and a locking member that cooperates with the driving part; when an external force is applied to the driving part, the locking member can abut against the transfer unit, so that the transfer unit switches from an active state to a locked state; or, when an external force is applied to the driving part, the locking member can disengage from the transfer unit, so that the transfer unit switches from a locked state to an active state.

[0044] Furthermore, the transfer roller has a blocking surface, and the locking member has a blocked surface that can cooperate with the blocking surface. When the blocking surface and the blocked surface abut against each other, the transfer unit enters a locked state.

[0045] Furthermore, the cleaning body is a solid cleaning soap, and the squeezing device also includes a pressing unit, which presses the solid cleaning soap toward the side where the transfer unit is located; the pressing unit includes at least a pressure plate in contact with the cleaning body and an elastic member abutting against the pressure plate.

[0046] Furthermore, the cavity and the dewatering frame are integrated; or, the cavity and the dewatering frame are separate components.

[0047] This utility model also discloses a hands-free flat mop, including a flat mop with a wiping agent, a mop handle rotatably connected to the flat mop, and the aforementioned squeezing device. The beneficial effects of this utility model are: 1) Both the squeezing component and the transfer unit can interact with the wiping agent on the flat mop within the wringing channel, achieving both squeezing and cleaning, and utilizing the cleaning agent for cleaning. This combines deep cleaning and rinsing of the flat mop's wiping agent into a single cleaning and squeezing device, resulting in a more thorough cleaning of the flat mop and a better cleaning effect. It is also convenient to operate, eliminating the need to move the flat mop to different locations for separate deep cleaning with the cleaning agent and rinsing with water; 2) The transmission unit and transfer unit can move under the drive of the flat mop, achieving cleaning... 1) The transfer of cleaning agents eliminates the need for manual spraying or application, reducing operational steps and making it more convenient to use; 2) The two steps of squeegee cleaning and cleaning with the cleaning agent can be performed simultaneously or separately, offering high flexibility and preventing excessive residue of cleaning agents on the wiped surface; 3) The transfer unit offers multiple switching modes between working and waiting states, and the transport unit offers multiple switching modes between active and locked states, suitable for different usage scenarios; 4) The transfer and transport units include rotatable transfer rollers with evenly distributed transfer teeth on their outer circumference, ensuring uniform distribution of cleaning agents to the wiped surface, preventing areas with excessive cleaning agents that cannot be rinsed clean, and areas with insufficient cleaning agents that cannot be effectively cleaned; 5) The transfer and transport units include rotatable transfer spheres, or the transport unit includes transfer rollers and scrapers, resulting in a large area of ​​cleaning agent scraping, fast cleaning agent transfer, faster adhesion of cleaning agents to all areas of the wiped surface, richer foaming of the cleaning agent, and better cleaning agent performance; 6) The positioning component ensures that the transfer unit remains stably in the working or waiting state during use. 8) The locking unit keeps the transfer unit firmly in the locked state, ensuring effective isolation between the two steps of squeegee cleaning and cleaning with the cleaning body, thus ensuring the cleaning effect of the flat mop; 9) The holding unit ensures that the transfer unit can still contact the cleaning body and effectively transfer it to the wiping object after long-term use; 10) The cleaning body can achieve a good stain removal effect on the flat mop and remove odors. The cleaning body can also increase the lubrication of the surface of the wiping object during cleaning, extending the service life of the wiping object; 11) The mesh design of the transfer part is simple and reduces processing costs.

[0098] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0099] A flat mop squeezing device includes a squeezing frame 1, a squeezing channel 11, a squeezing member 2 located in the squeezing channel 11, a cavity 3 for storing cleaning material, and a transfer part. The squeezing channel 11 is for inserting a flat mop 9, and the flat mop 9 can be pulled up and down and pushed relative to the squeezing channel 11. The squeezing member 2 is used to squeeze the wiping material of the flat mop 9.

[0100] The transfer section can contact the cleaning body and the flat mop 9 respectively, and is used to transfer the cleaning body in the cavity 3 to the wiping material of the flat mop 9. The specific location of the transfer section is not limited here. It can be located between the cavity 3 and the wringing channel 11, or at least part of the transfer section can be located between the cavity 3 and the wringing channel 11.

[0101] The specific structure of the transfer unit is not limited here. It can be a stationary structure relative to the wringer 1, that is, the transfer unit will not move; or it can be a movable structure, that is, the transfer unit can move relative to the flat mop 9. The movement here includes rotation, movement, and a combination of rotation and movement. It can be a concave-convex structure or a smooth flat structure. As long as it can realize the transfer of cleaning material to the flat mop 9, or more precisely, the transfer of wiping material to the flat mop 9, it is acceptable.

[0102] The following describes the specific implementation structure of the transfer unit through multiple embodiments. Example 1

[0103] As shown in Figures 1-9, a squeezing device for a flat mop includes a wringer 1, a squeezing element 2, a cavity 3, and a transmission unit 4. In this embodiment, the transfer unit is located in the transmission unit 4.

[0104] The wringer 1 has a wringing channel 11 for inserting the flat mop 9. Alternatively, the wringer 1 and the cavity 3 can be combined to form the wringing channel 11. No specific limitation is made. The flat mop 9 can be pulled up and down and pushed inside the wringing channel 11. In other words, the flat mop 9 and the wringing channel 11 move relative to each other to achieve the up and down pulling and pushing of the flat mop 9.

[0105] The location of the extrusion component 2 is not limited at the moment. It is used to extrude the wiping material of the flat mop 9 and to clean the flat mop 9 by pulling and pushing it up and down.

[0106] The cavity 3 is located on the wringer 1 and is used to store the cleaning agent. The cleaning agent is not limited; it can be a liquid detergent or a solid cleaning soap, such as regular soap. The cavity 3 can be a separate component within the wringer 1, or it can be integrated with the wringer 1. This structure also corresponds to the formation of the wringing channel 11. When the wringer 1 and the cavity 3 are relatively independent, the wringing channel 11 is formed by the wringer 1. When the wringer 1 and the cavity 3 are connected, the wringing channel 11 is formed by the wringer 1. Of course, the cavity 3 does not have to be a relatively independent component; it can be broadly understood as part of the structure corresponding to the storage of the cleaning agent.

[0107] At least a portion of the transmission unit 4 can interact with the flat mop 9. The interaction between the transmission unit 4 and the flat mop 9 can be either driven by the flat mop 9 pulling and pushing up and down in the wringing channel 11, or the two can work together when the flat mop 9 pulls and pushes up and down in the wringing channel 11. The specific interaction is not limited. This is used to transfer the cleaning material in the cavity 3 to the wiping material of the flat mop 9. The transmission unit 4 has at least a transfer part that can rotate relative to the flat mop 9. The transfer part has a concave-convex structure for acquiring the cleaning material. As shown in Figure 7, in this embodiment, the transfer part is a transfer roller 41, and its outer wall is evenly distributed with transfer teeth 411. The transfer teeth 411 are the concave and convex structures used to obtain the cleaning body. The transfer roller 41 can rotate around the rotating shaft 42, so that the cleaning body in the cavity 3 is first transferred into the space between adjacent transfer teeth 411, and then the cleaning body is transferred to the wiping object through the contact between the wiping object and the transfer teeth 411. By utilizing the continuous rotation of the transfer roller 41, the cleaning body in the cavity 3 is continuously transported to the wiping object.

[0108] The transmission unit 4 has at least a working state and a waiting state. In the working state, at least part of the transmission unit 4 contacts or tends to contact the wiping material of the flat mop 9, thereby transmitting the cleaning material in the cavity 3 to the wiping material. This allows the flat mop 9 to perform deep cleaning of the cleaning material while being pulled out and squeezed in the wringing channel 11, resulting in a better cleaning effect. In the waiting state, the transmission unit 4 stops transmitting the cleaning material to the wiping material. At this time, the flat mop 9 is pulled out and squeezed in the wringing channel 11 to complete the rinsing of the wiping material, thus avoiding the flat mop 9 leaving too much cleaning material on the wiping material when mopping.

[0109] It should be noted that the statement that "at least a portion of the transmission unit 4 tends to contact the wiping material of the flat mop 9" means that it is possible for the transmission unit 4 not to come into contact with the wiping material of the flat mop 9, but the transmission unit 4 has already brought the cleaning body into contact with the wiping material. The statement that "at least a portion of the transmission unit 4" refers to situations where the entire transmission unit 4 is in contact with the wiping material, only a small portion of the transmission unit 4 is in contact with the wiping material, or the vast majority of the transmission unit 4 is in contact with the wiping material.

[0110] The switching between the working state and the waiting state of the transmission unit 4 can be achieved by changing the relative position of at least a portion of the transmission unit 4 and the wringer 1. Alternatively, it can be achieved by changing the relative position of at least a portion of the cavity 3 and at least a portion of the transmission unit 4. It should be noted that the at least a portion of the cavity 3 here includes the cleaning body within the cavity 3.

[0111] Specifically, the transmission unit 4 and the cavity 3 are movably connected to the dewatering rack 1. The transmission unit 4 and the cavity 3, as a whole, can move relative to the dewatering rack 1. This movement can be translational or non-linear, thereby enabling the transmission unit 4 to switch between a working state and a waiting state (the specific structure will be explained in Embodiments 1, 3, and 4). It should be noted that translation here does not refer to horizontal movement, but rather to linear movement. It can be translation in the horizontal direction, vertical direction, or inclined direction, without any specific limitation (the translation mentioned below is interpreted in this way). Alternatively, the transmission unit 4 can be rotatably connected to the dewatering rack 1. This means that a part of the transmission unit 4 can rotate around its own axis, and the transmission unit 4 can rotate relative to the dewatering rack 1, such that the transmission unit 4 rotates to the side of the dewatering rack 1 facing the dewatering channel 11, or rotates to the side away from the dewatering channel 11, thereby enabling the transmission unit 4 to switch between a working state and a waiting state (the specific structure will be explained in Embodiment 7). Alternatively, at least a portion of the cavity 3 can move relative to the wringer 1, thereby changing the relative position of at least a portion of the transmission unit 4 with respect to the cleaning body, thus switching the transmission unit 4 between a working state and a waiting state (the specific structure will be described in Embodiment Six). It should be noted that at least a portion of the cavity 3 here can be the cavity 3 itself, or it can include the cleaning body within the cavity 3. Alternatively, the transmission unit 4 can be movably connected to the wringer 1, and at least a portion of the transmission unit 4 can move relative to the wringer 1. This movement can be translational or non-linear, causing the transmission unit 4 to approach the cleaning body within the cavity 3 and scrape the cleaning body to convey it to the wiping material, thereby switching the transmission unit 4 between a working state and a waiting state (the specific structure will be described in Embodiment Five). Furthermore, the transmission unit 4 can be movably connected to the wringer 1, and at least a portion of the transmission unit 4 can move relative to the wringer 1. This movement can be translational or non-linear, causing the transmission unit 4 to approach or move away from the wringer channel 11, thereby switching the transmission unit 4 between a working state and a waiting state.

[0112] Specifically, in the structure of this embodiment, as shown in Figures 4 and 7, the squeezing member 2 is fixedly disposed on the side of the wringer 1 facing the wringing channel 11. Of course, the squeezing member 2 can also be movably connected to the wringer 1, and there is no specific limitation. The cavity 3 is movably disposed on the wringer 1, with one side of the cavity 3 open. The transmission unit 4 is connected to the open side of the cavity 3, specifically disposed on the side of the cavity 3 facing the wringing channel 11. Under the drive of an external force, the cavity 3 can move relative to the wringer 1, thereby allowing the transmission unit 4 to switch between a working state and a waiting state. Taking the direction shown in Figures 3 and 4 as an example, the cavity 3 can move left and right relative to the wringer 1. When the cavity 3 moves to the right, the transmission unit 4 is closer to the wiping material of the flat mop 9, causing the transmission unit 4 to enter the working state. When the cavity 3 moves to the left, the transmission unit 4 moves away from the wiping material of the flat mop 9, causing the transmission unit 4 to enter the waiting state.

[0113] Taking Figures 3 and 4 as examples, the transmission unit 4 is in a waiting state, located on the side of the squeezing member 2 away from the wringing channel 11, that is, the transmission unit 4 is located to the left of the squeezing member 2. When the flat mop 9 enters the wringing channel 11 and is pulled out, only the squeezing member 2 is active, and the transmission unit 4 does not transfer the cleaning material to the wiping object. When the transmission unit 4 enters the working state, it moves to the right, becoming flush with the squeezing member 2. When the flat mop 9 enters the wringing channel 11 and is pulled out, the squeezing member 2 is active, and the transmission unit 4 transfers the cleaning material to the wiping object.

[0114] More specifically, as shown in Figures 7-9, in this embodiment, the transmission unit 4 includes two transmission rollers 41 rotatably connected to the cavity 3, arranged parallel to the pulling direction of the flat mop 9. In other words, the two transmission rollers 41 are arranged vertically, and multiple transmission teeth 411 are evenly distributed around the outer wall of the transmission rollers 41, thereby uniformly transmitting the cleaning material to the wiping object and avoiding uneven distribution of the cleaning material. Of course, in other embodiments, the number of transmission rollers 41 is not limited; it can be one or more.

[0115] To facilitate assembly, the sidewall of the cavity 3 is formed with an elastic mounting sidewall structure, and a rotating shaft 42 is formed on the inner side of the elastic mounting sidewall. The transmission roller 41 is inserted between the two rotating shafts 42, and the transmission roller 41 can rotate around the rotating shaft 42. Thus, the cleaning body located in the cavity 3 can be transmitted to the wiping object under the rotation of the transmission roller 41. More specifically, the inner side of the transmission roller 41 contacts the cleaning body in the cavity 3, and after rotating, it drives it outward, continuously rotating in the same direction to realize the continuous transmission of the cleaning body.

[0116] For ease of assembly and relatively stable structure after assembly, the dewatering frame 1 is divided into upper and lower frames. The extrusion component 2 is fixedly connected to the upper frame of the dewatering frame 1, and the cavity 3 is movably connected to the lower frame. Both the cavity 3 and the extrusion component 2 extend across the entire width of the dewatering frame 1.

[0117] In this embodiment, the driving component 6 is used to drive the cavity 3 to translate. At least a part of the driving component 6 translates or rotates, thereby driving the cavity 3 to translate relative to the wringer 1. Specifically, in this embodiment, the driving component 6 includes at least a shifting groove 12 formed on the wringer 1, a shifting member 61 movably connected to the wringer 1, and a movable track 62 formed on the cavity 3. The shifting groove 12 extends along the width direction of the wringer 1. A part of the shifting member 61 extends into the movable track 62, and a part of the shifting member 61 is located in the shifting groove 12. When an external force is applied to drive the shifting member 61 to move relative to the wringer 1 within the shifting groove 12, the cavity 3 can extend or retract from the wringer 1.

[0118] As shown in Figures 10 and 11, part of the actuating member 61 extends from the top of the wringer 1 and through the actuating transverse groove 12. After passing through the extruder 2, part of the actuating member 61 engages with the movable track 62. In this embodiment, there are two movable tracks 62. Correspondingly, two slide rail structures 21 are also provided at corresponding positions on the extruder 2. The actuating member 61 is provided with two actuating parts 611 that can extend into the movable tracks 62.

[0119] As shown in Figure 9, the movable track 62 includes a first slide 621, a second slide 622 parallel to the first slide 621, and a transition slide 623 connecting the first slide 621 and the second slide 622. The transition slide 623 is inclined. Of course, the first slide 621 and the second slide 622 do not necessarily have to be completely parallel; they only need to be not on the same straight line. Specifically, the first slide 621 extends along the width of the cavity 3. The entire movable track 62 is a Z-shaped slide. Here, a Z-shaped slide refers to a shape that is close to a Z shape. It does not necessarily have to be a standard Z shape; it can also be a mirror image of a Z. The first slide, the second slide, and the transition slide do not necessarily have to be straight tracks; they can also be curved tracks, as long as the first slide 621 and the second slide 622 have a height difference and are connected to each other. The specific shape is not limited.

[0120] When an external force is applied to cause the actuating member 61 to move relative to the squeezing frame 1 within the actuating transverse groove 12, the two actuating parts 611 of the actuating member 61 can only move laterally due to the restriction of the actuating transverse groove 12. Once it moves beyond the lateral width of the first slide groove 621 or the second slide groove 622, it will inevitably enter the transition slide groove 623. Since the actuating part 611 can only move laterally, the actuating part 611 moves against the transition slide groove 623, and the cavity 3 moves inward and outward under the drive of the actuating part 611.

[0121] To ensure that the transmission unit 4 remains stably in either the working or waiting state, a positioning component 7 is included to limit the transmission unit 4 to either the working or waiting state. In this embodiment, as shown in Figures 5 and 6, the positioning component 7 cooperates with the drive component 6 in a limiting manner. Specifically, the positioning component 7 is a rib structure provided on the wringer 1. This rib can abut against the actuating member 61 of the drive component 6, thereby stopping the actuating member 61 in that position. Only by applying a greater external force can the actuating member 61 be moved past the rib to switch to another state. There is at least one rib, which can cooperate with two grooves, allowing the actuating member 61 to remain in either the working or waiting state of the transmission unit 4. Of course, in other embodiments, other limiting structures from the prior art can also be used; no specific limitation is imposed.

[0122] Of course, the structure can be simplified. The drive component 6 can also include a longitudinal groove structure opened on the squeezing frame 1 and a toggle member connected to the cavity 3. When an external force is applied to drive the toggle member to move in the longitudinal groove, the cavity 3 is driven to move synchronously closer to or away from the squeezing channel 11, so as to achieve the purpose of the transmission unit 4 moving closer to or away from the squeezing channel 11, and the transmission unit 4 switching between the working state and the waiting state.

[0123] When the cleaning agent in the cavity 3 is a solid cleaning soap, its volume decreases after prolonged use. To ensure it remains in effective contact with the transmission unit 4, the extrusion device may also include a holding unit 8, which presses the solid cleaning soap against the side where the transmission unit 4 is located. Specifically, the holding unit 9 includes at least a pressure plate 81 that contacts the cleaning agent and an elastic member that abuts against the pressure plate 81. The other end of the elastic member abuts against the side wall of the cavity 3. As the volume of the cleaning agent in the cavity 3 deforms, the compressed elastic member 82 continuously elongates, using the pressure plate 81 to push the cleaning agent towards the transmission unit 4.

[0124] A hands-free flat mop includes a flat mop 9 with a wiping agent, a mop handle 91 rotatably connected to the flat mop 9, and a squeezing device with the above structure.

[0125] During use, in the initial state, the transmission unit 4 is in a waiting state, that is, the cavity 3 and the transmission unit 4 are located on the side of the extruder 2 away from the squeezing channel 11. At this time, when the flat mop 9 is pulled up and down in the squeezing channel 11 and pushed up and down relative to the extruder 2, the cleaning body will not be transferred to the wiping material of the flat mop 9. When it is necessary to use the cleaning body to clean the wiping material of the flat mop 9, an external force is applied to the actuating member 61, causing the actuating member 61 to move horizontally in the actuating groove 12, and the actuating part 611 to move in the movable track 62. Specifically, the actuating part 611 moves from the second slide groove 622 through the transition slide groove 623 into the first slide groove 621, so that the cavity 3. Move relative to the wringer 1 towards the wringer channel 11. At this time, when the flat mop 9 is pulled up and down in the wringer channel 11, the wiping material not only squeezes against the squeezing member 2, but also contacts and interacts with the transfer roller 41. That is, the transfer roller 41 rotates around the rotating shaft 42 under the drive of the wiping material, thereby transferring the cleaning body in the cavity 3 to the wiping material, so that the wiping material is cleaned by the cleaning body while being squeezed against the squeezing member 2. Due to the limiting cooperation between the positioning component 7 and the driving component 6, the actuating part 61 can be stably stopped in the slide groove 621, that is, the transfer roller 41 on the cavity 3 is kept in the state of extending out of the wringer 1. Example 2

[0126] As shown in Figures 12-14, the difference between this embodiment and Embodiment 1 is that the transfer unit is a transfer ball 43, which is rolled within a circular hole 431, which is formed on the side wall of the cavity 3. There are multiple circular holes 431, and correspondingly multiple transfer balls 43, which are spaced apart on the same plane of the cavity 3, allowing all parts of the wiping object to receive the cleaning material transported by the transfer ball 43. Of course, the multiple transfer balls 43 may not be located on the same plane; there is no specific limitation. The outer wall of the transfer ball 43 has grooves 432, which are the concave-convex structures used to acquire the cleaning material. When the transfer ball 43 rolls, it can transfer the cleaning material in the cavity 3 to the wiping object.

[0127] The other structures are the same as in Embodiment 1, and will not be described again. Example 3

[0128] The difference between this embodiment and Embodiment 1 is that at least a portion of the drive component 6 rotates, thereby causing the cavity 3 to translate relative to the squeezing frame 1.

[0129] As shown in Figures 15-20, the drive assembly 6 includes a drive wheel 63, an external threaded section 631 extending vertically from the center of the drive wheel 63, and an internal threaded portion 31 disposed in the cavity 3.

[0130] Specifically, the wringer 1 and the cavity 3 are relatively independent. The drive wheel 63 is rotatably connected to the wringer 1, and part of the drive wheel 63 extends out of the surface of the wringer 1. A flat plate is connected to the outer wall of the cavity 3. The flat plate forms a notch for supporting the external threaded section 631, and the inner wall of the notch forms an internal threaded section 31.

[0131] When an external force is applied to rotate the drive wheel 63, the external thread section 631 and the internal thread section 31 engage, which can drive the cavity 3 to move. For example, when the drive wheel 63 rotates in the forward direction, the cavity 3 moves away from the squeezing channel 11, so that the wiping material can only contact the extruder 2, but cannot contact the cleaning body of the transmission unit 4, or in other words, cannot contact the transmission ball 43, so that the transmission ball 43 cannot rotate to continuously transport the cleaning body in the cavity 3 to the wiping material. At this time, the transmission unit 4 enters the waiting state. When the drive wheel 63 rotates in the reverse direction, the cavity 3 moves closer to the squeezing channel 11, and the transmission unit 4 enters the working state. Example 4

[0132] In this embodiment, at least a portion of the drive component 6 rotates, thereby causing the cavity 3 to translate relative to the dewatering frame 1.

[0133] As shown in Figures 21-26, the drive assembly 6 includes a rotating wheel 64, a drive post 641 eccentrically mounted on the rotating wheel 64, and a transverse groove 32 disposed in the cavity 3. Specifically, the dewatering frame 1 and the cavity 3 are relatively independent, the rotating wheel 64 is rotatably connected to the dewatering frame 1, and the drive post 641 is engaged in the transverse groove 32, that is, the outer diameter of the drive post 641 is approximately equal to the width of the transverse groove 32.

[0134] When an external force is applied to rotate the rotating wheel 64, the drive column 641 can move within the transverse groove 32, thereby driving the cavity 3 to move. For example, when the rotating wheel 64 rotates clockwise, the cavity 3 moves away from the squeezing channel 11, so that the wiping material can only contact the squeezing element 2, but cannot contact the cleaning body of the transmission unit 4, or in other words, cannot contact the transmission ball 43, so that the transmission ball 43 cannot rotate to continuously transport the cleaning body in the cavity 3 to the wiping material. At this time, the transmission unit 4 enters the waiting state. When the rotating wheel 64 rotates counterclockwise, the cavity 3 moves closer to the squeezing channel 11, and the transmission unit 4 enters the working state.

[0135] To limit the transmission unit 4 to either the working or waiting state, as shown in Figure 26, a limiting protrusion 642 is provided on the rotating wheel 64, and as shown in Figure 23, a limiting groove 13 is provided on the dewatering frame 1. When the limiting protrusion 642 falls into the limiting groove 13, the transmission unit 4 is limited to the working state. Similarly, another limiting groove (not shown in the figure) can be provided on the cavity 3. When the limiting protrusion 642 falls into the limiting groove 13 of the cavity 3, the transmission unit 4 is limited to the waiting state. Example 5

[0136] The difference between this embodiment and Embodiment 1 is that the structure of the transmission unit 4 is different.

[0137] As shown in Figures 27-30, the transmission unit 4 includes a transmission roller 41 and a scraper 47. Both the transmission roller 41 and the scraper 47 are positioned facing the squeezing channel 11, with the transmission roller 41 located above the scraper 47. When the flat mop 9 is pulled up and down, it drives the transmission roller 41 to rotate. Simultaneously, the rotation of the transmission roller 41 causes the scraper 47 to move, thereby enabling the scraper 47 to scrape the cleaning material.

[0138] As shown in Figure 29, in this embodiment, the transmission roller 41 is a drive roller, which is rotatably connected to the wringer 1 and can contact the wiping material of the flat mop 9. Under the drive of the wiping material, it rotates relative to itself around its own axis 462. The drive roller is also eccentrically connected to a crank part 461, that is, the center line of the crank part 461 does not overlap with the center line of the axis 462.

[0139] As shown in Figure 30, the scraper 47 is used to scrape off the cleaning agent. This scraper is connected to a movable groove 471 into which the crank portion 461 extends. The width of the movable groove 471 is approximately equal to the outer diameter of the crank portion 461, and the length of the movable groove 471 is greater than the outer diameter of the crank portion 461. When the drive roller rotates relative to the wringer 1, the crank portion 461 moves up and down within the movable groove 471, thereby driving the scraper to move up and down. In this embodiment, the cleaning agent is solid cleaning soap. During the upward or downward movement of the scraper, the solid cleaning soap can be scraped off and transferred to the wiping material. In other words, the transfer roller 512 may not be used to scrape off the cleaning agent at this time; however, it is not impossible for the transfer roller 512 and the scraper 47 to simultaneously scrape off the cleaning agent.

[0140] When the transmission roller 41 rotates relative to the scraper 47 and moves it up and down, the transmission unit 4 enters the working state. When the transmission roller 41 stops rotating relative to the scraper 47 and cannot move it up and down, the transmission unit 4 enters the waiting state.

[0141] In this embodiment, the positioning component 7 for limiting the transmission unit 4 to a working state or a waiting state specifically includes a knob 71 that partially protrudes from the surface of the extrusion device, a locking member 72 connected to the knob 71, and a meshing tooth portion 73 and a clearance portion 74 located on the outer wall of the drive roller. The locking member 72 can move relative to the meshing tooth portion 73, allowing it to switch between two states: engaging with the meshing tooth portion 73 and engaging with the clearance portion 74.

[0142] When an external force is applied to the dial 71, causing the locking member 72 to engage with the meshing teeth 73, the drive roller stops rotating under the action of the locking member 72. At this time, the drive roller cannot drive the scraper to move up and down, meaning that there is no mutual friction scraping action between the scraper and the cleaning body, and the transmission unit 4 enters the waiting state. The avoidance part 74 has a groove structure. When an external force is applied in the opposite direction to the dial 71, causing the locking member 72 to disengage from the meshing teeth 73, and the locking member 72 enters the corresponding position of the avoidance part 74, the meshing teeth on the locking member 72 are inside the avoidance part 74, and they do not interact with the drive roller. The drive roller can rotate freely, so the scraper can move up and down (here, up and down is illustrated in the direction shown in Figure 28) under the drive of the drive roller to scrape the cleaning body, and the transmission unit 4 enters the working state.

[0143] Another function of the biting teeth 73 is to better transmit the force of the wiping material to the drive roller, allowing the drive roller to rotate around its own axis 462. In this structure, both the drive roller and the scraper can be understood as the transfer part of the transfer unit 4. The scraper can be understood as the concave and convex structure on the transfer part. Specifically, in this embodiment, the scraper can be a mesh structure, and the cleaning material is transferred from the gaps to the wiping material.

[0144] In this embodiment, the wringer 1 and the cavity 3 are connected together. That is to say, the cavity 3 is not an independent component, but can be generally understood as a part of the structure corresponding to the storage of the cleaning body. Example 6

[0145] The difference between this embodiment and Embodiment 1 is that the structure of the transmission unit 4 is different.

[0146] As shown in Figures 31-34, the transmission unit 4 includes a first part 44 and a second part 45. The first part 44 is disposed facing the squeezing channel 11, and the second part 45 is opposite to the first part 44. The two are located on opposite sides of the cleaning body. The cleaning body in the cavity 3 can move relative to the squeezing frame 1 under the drive of the second part 45, so that the cleaning body can contact or move away from the first part 44 of the transmission unit 4. Specifically, the cleaning body can move inward and outward under the action of the second part 45.

[0147] The structure of the first part 44 is similar to that of Embodiment 1. It is a transmission roller structure that is rotatably connected to the dewatering frame 1 or the cavity 3. Further details will not be provided. In this embodiment, the dewatering frame 1 and the cavity 3 are connected together. That is to say, the cavity 3 is not an independent component; it can be generally understood as part of the structure corresponding to the storage of the cleaning body, and there is no clear boundary between it and the dewatering frame 1.

[0148] The second part 45 includes a lifting member 451 and a lifting member 452 rotatably connected to the cavity 3 or the squeezing frame 1, a movable member 453 connected to the lifting member 451, a movable member 454 connected to the lifting member 452, and a force-applying member 455. The lifting members 451 and 452 extend the entire width of the extrusion device and are generally rod-shaped. Crucially, both the lifting members 451 and 452 are equipped with lifting levers 450, and the lifting member 451 is also connected to an extension arm 459.

[0149] There are at least two movable parts 453, located at both ends of the lifting part 451 and connected to it at an angle. Similarly, there are at least two movable parts 454, located at both ends of the lifting part 452 and connected to it at an angle. Movable parts 453 are provided with vertical sliding columns 456, and movable parts 454 are provided with track grooves 457. After assembly, the sliding columns 456 fall into the track grooves 457.

[0150] As shown in Figure 34, the force-applying component 455 has an arc-shaped slide rail 458. When an external force is applied to cause the force-applying component 455 to translate relative to the extrusion device, the arc-shaped slide rail 458 drives the extension arm 459 to move, causing the lifting component 451 to rotate, which in turn drives the lifting lever 450 to rotate. At this time, the sliding column 456 moves in the track groove 457, and the lifting lever 450 on the lifting component 452 also rotates. Therefore, the lifting components 451 and 452 cooperate to lift the cleaning body away from the first part 44, at which time the transmission unit 4 enters the waiting state; or the lifting components 451 and 452 cooperate to move the cleaning body closer to the first part 44, at which time the transmission unit 4 enters the working state.

[0151] In this embodiment, the positioning component 7 can be a slot structure set at both ends of the arc-shaped slide rail 458, which is equivalent to the positioning component 7 and the transmission unit 4 being matched in a limiting manner, and there is no specific limitation. Example 7

[0152] As shown in Figures 35 and 36, in this embodiment, the transmission unit 4 and the extruder 2 are both disposed on the cavity 3, and the cavity 3 is rotatably connected to the dewatering frame 1, forming a dewatering channel 11 between the dewatering frame 1 and the cavity 3.

[0153] Applying external force to knob 13 causes cavity 3 to rotate relative to wringer 1. When squeezer 2 rotates to face wringer channel 11, transfer unit 4 is located away from wringer channel 11; conversely, when transfer unit 4 faces wringer channel 11, squeezer 2 is located away from wringer channel 11. In other embodiments, transfer unit 4 can also be located on the upper side, i.e., the side of transfer unit 4 forms a 90° angle with the side of squeezer 2. In other words, squeezer 2 and transfer unit 4 are not simultaneously in operation. When squeezer 2 presses against the wiping material, transfer unit 4 enters a waiting state; when transfer unit 4 is in operation, squeezer 2 is not in use. Cavity 3 rotates squeezer 2 and transfer unit 4 relative to wringer 1, allowing transfer unit 4 to switch between operating and waiting states.

[0154] The specific structure of transmission unit 4 is similar to that of Embodiment 1, and will not be described again. Example 8

[0155] As shown in Figures 37-39, the squeezing member 2 and the cavity 3 are fixed relative to each other on the wringing frame 1. The transmission unit 4 is located on the side of the cavity 3 facing the wringing channel 11, and the squeezing member 2 also faces the wringing channel 11. The squeezing member 2 and the transmission unit 4 are arranged vertically, so they can simultaneously squeeze the wiping material from the flat mop 9. Relatively speaking, the squeezing member 2 is slightly closer to the wringing channel 11, and the transmission unit 4 is slightly farther away from the wringing channel 11. The wringing frame 1 is also provided with a blocking unit 5. This blocking unit 5 can pass through the squeezing member 2 and move to the opposite side of the transmission unit 4. In other words, the blocking unit 5 can pass through the squeezing member 2 and move between the wiping material and the transfer part of the transmission unit 4, thereby isolating the transmission unit 4 and the wiping material. Of course, the blocking unit 5 may not pass through the extruder 2, but may pass through the extruder 2 and the transfer unit, or the blocking unit 5 may move to the location between the wiping material and the transfer unit, or the blocking unit 5 may move to the location between the cleaning body and the transfer unit. There are no specific restrictions. Its ultimate purpose is to isolate the transfer unit of the transmission unit 4 from the wiping material.

[0156] Alternatively, the extruder 2 can be fixedly connected to the wringer 1, and the blocking unit 5 can move from below the extruder 2 to the opposite side of the transfer unit 4, thus isolating the transfer section from the wiping material. Alternatively, the extruder 2 can be fixedly connected to the wringer 1, with a gap between the extruder 2 and the wringer 1, allowing the blocking unit 5 to move through this gap to the opposite side of the transfer section. In the above structures, the blocking unit 5 moves from top to bottom to the opposite side of the transfer unit 4. In other embodiments, the blocking unit 5 can move from the side of the transfer unit 4 to directly opposite it; there are no specific limitations. The blocking unit 5 can be a plate-like structure capable of certain deformation but also possessing a certain rigidity; there are no specific limitations.

[0157] Of course, the aforementioned extrusion component 2 can also be movably connected to the dewatering frame 1, and there are no specific restrictions.

[0158] During use, when only the squeezing part 2 is needed, the blocking unit 5 is moved to the opposite side of the transmission unit 4 so that the cleaning material in the cavity 3 will not be transmitted to the wiping material of the flat mop 9 through the transmission unit 4. At this time, the transmission unit 4 enters the waiting state. When the cleaning material is needed, the blocking unit 5 is moved back so that both the transmission unit 4 and the squeezing part 2 can come into contact with the wiping material of the flat mop 9. At this time, the transmission unit 4 enters the working state.

[0159] Of course, the aforementioned blocking unit can also be placed between the transfer unit 04 transfer section and the wiping material in Embodiment 11. Example 9

[0160] In this embodiment, unlike in embodiment one, the cavity 3 and the extruder 2 are movably connected to the dewatering frame 1, and the transmission unit 4 is located on the side of the cavity 3 facing the dewatering channel 11. Under the action of external force, the relative movement of the cavity 3 and the dewatering frame 1, and the relative movement of the extruder 2 and the dewatering frame 1 can be realized respectively.

[0161] When the squeezing element 2 needs to squeeze the wiping material, it extends relative to the wringer 1. At this time, the transmission unit 4 can retract into the wringer 1, meaning that only the squeezing element 2 squeezes the wiping material within the wringing channel 11. When the transmission unit 4 needs to contact the wiping material, it extends relative to the wringer 1. At this time, the squeezing element 2 can retract into the wringer 1, meaning that only the transmission unit 4 contacts the wiping material within the wringing channel 11. Alternatively, both the squeezing element 2 and the transmission unit 4 can extend relative to the wringer 1, so that both the squeezing element 2 and the transmission unit 4 can function when the flat mop 9 is pulled up and down within the wringing channel 11.

[0162] The structure of the transmission unit 4 is the same as that of Embodiment 1. The structure of the drive cavity 3 and the extruder 2 moving relative to the dewatering frame 1 can also be similar to that of Embodiment 1, and will not be described in detail here. Example 10

[0163] In this embodiment, at least a portion of the drive component 6 translates and rotates, thereby moving the cavity 3 relative to the squeezing frame 1 so that the cavity 3 moves closer to or further away from the squeezing channel 11.

[0164] Specifically, the drive assembly 6 includes a paddle with straight teeth, a gear meshing with the straight teeth of the paddle, and a movable member with straight teeth that also meshes with the paddle. Simultaneously, the movable member is connected to the cavity 3. Thus, when an external force is applied to the paddle to cause it to translate, the straight teeth of the paddle drive the gear to rotate, which in turn moves the movable member, causing the cavity 3 to move closer to or further away from the squeezing channel 11.

[0165] The other structures are the same as in Embodiment 1, and will not be described again. Example 11

[0166] As shown in Figures 40-45, a flat mop squeezing device includes a squeezing frame 1, a squeezing channel 11, a squeezing component 2, a cavity 3, and a transfer unit 04. In this embodiment, the transfer part is located in the transfer unit 04.

[0167] In this embodiment, the cleaning agent is a solid cleaning soap. Of course, the cavity 3 does not have to be a relatively independent component; it can be generally understood as the part of the structure corresponding to the storage of the cleaning agent.

[0168] The squeezing component 2 is located in the wringing channel 11. Specifically, it can be fixedly connected to the wringing frame 1 on the side facing the wringing channel 11, or it can be movably connected to the wringing frame 1 on the side facing the wringing channel 11; alternatively, the squeezing component 2 can be fixedly connected to the cavity 3 on the side facing the wringing channel 11, or it can be movably connected to the cavity 3 on the side facing the wringing channel 11. The squeezing component 2 is used to squeeze the wiping material on the flat mop 9, enabling the flat mop 9 to be pulled up and down and pushed to clean.

[0169] At least a portion of the transfer unit 04 can interact with the flat mop 9 to cause at least a portion of the transfer unit 04 to move. The interaction between the transfer unit 04 and the flat mop 9 can be either that the flat mop 9 drives at least a portion of the transfer unit 04 to move when it moves up and down within the wringing channel 11, or that the flat mop 9 and at least a portion of the transfer unit 04 work together when it moves up and down within the wringing channel 11. The specific interaction is not limited, thereby transferring the cleaning material in the cavity 3 to the wiping material on the flat mop 9.

[0170] The transfer unit 04 has at least a transfer section that can rotate relative to the flat mop 9. This transfer section has a concave-convex structure for acquiring the cleaning material. As shown in Figure 43, in this embodiment, the transfer section is a transfer roller 41, whose outer wall is evenly distributed with transfer teeth 411. These transfer teeth 411 are the concave-convex structure for acquiring the cleaning material. The transfer roller 41 can rotate around the rotating shaft 42, thereby first transferring the cleaning material in the cavity 3 into the space between adjacent transfer teeth 411, and then transferring the cleaning material to the wiping material through contact between the wiping material and the transfer teeth 411. By continuously rotating the transfer roller 41, the cleaning material in the cavity 3 is continuously transported to the wiping material. Of course, it is not excluded that the transfer section of the transfer unit 04 does not have a concave-convex structure; the transfer section can also achieve the transfer of the cleaning material as a smooth plane. In addition, the concave-convex structure here also includes structures with small concave-convex surfaces, such as rough surfaces.

[0171] The transfer unit 04 has at least an active state and a locked state. In the active state, at least a portion of the transfer unit 04 is activated, thereby conveying the cleaning material in the cavity 3 to the wiping object. This allows the flat mop 9 to perform deep cleaning of the cleaning material while being pulled and wrung out in the wringing channel 11, resulting in a better cleaning effect. Specifically, in this embodiment, the transmission roller 41 rotates around the rotating shaft 42, causing the transmission teeth 411 to continuously scrape the cleaning material in the cavity 3 and rotate and convey it towards the wringing channel 11. This allows the cleaning material between the transmission teeth 411 to effectively adhere when the flat mop 9 is pulled and wrung out in the wringing channel 11.

[0172] In the locked state, the transfer unit 04 stops moving, thereby stopping the conveying of cleaning material from the cavity 3 to the wiping material. At this time, the flat mop 9 is pulled out and wrung out in the wringing channel 11 to complete the rinsing of the wiping material, avoiding the retention of too much cleaning material on the wiping material when the flat mop 9 is mopping. In the specific structure of this embodiment, the transmission roller 41 stops rotating, and even if the transmission teeth 411 facing the cavity 3 scrape the cleaning material, they cannot rotate and convey it to the wringing channel 11 side. When the flat mop 9 is pulled out in the wringing channel 11, the cleaning material cannot adhere to it.

[0173] The switching between the active and locked states of the transfer unit 04 is achieved using a locking unit 10. The locking unit 10 includes a drive unit 101, a locking member 102 cooperating with the drive unit 101, and an elastic reset member 103. The elastic reset member 103 abuts against the locking member 102, the dewatering frame 1, or the cavity 3, respectively, to press the locking member 102 towards the direction of the transfer unit 04. Specifically, when the dewatering frame 1 and the cavity 3 are combined to form a dewatering channel 11, one end of the elastic reset member 103 abuts against the cavity 3, and the drive unit 101 can be connected to the cavity 3, allowing the drive unit 101 to translate relative to the cavity 3. When the dewatering frame 1 forms the dewatering channel 11, one end of the elastic reset member 103 abuts against the cavity 3 or against the dewatering frame 1, and the drive unit 101 can be connected to the dewatering frame 1, allowing the drive unit 101 to translate relative to the dewatering frame 1. The aforementioned drive unit 101 and lock member 102 can be integrated into one unit or can be separate units.

[0174] When an external force is applied to the drive unit 101, the locking member 102 can abut against the transfer unit 04, thereby switching the transfer unit 04 from an active state to a locked state. In this case, the elastic reset member 103 is not required. By applying an opposite external force to the drive unit 101, the transfer unit 04 can be switched from a locked state to an active state. In this case, the locking unit 10 includes the drive unit 101 and the locking member 102, which can be integrally formed. Alternatively, an elastic reset member can be provided, whose force acting on the drive unit 101 is a force that moves the locking member 102 away from the transfer unit 04.

[0175] Alternatively, when an external force is applied to the drive unit 101, the locking member 102 can disengage from the state of being in contact with the transfer unit 04, thereby causing the transfer unit 04 to switch from the locked state to the active state. At this time, an elastic reset member 103 is provided to stop the application of external force to the drive unit 101. Under the action of the elastic reset member 103, the locking member 102 can be in contact with the transfer unit 04, that is, the transfer unit 04 switches from the active state to the locked state.

[0176] As shown in Figure 44, for the structure where the locking member 102 abuts against the transfer unit 04, the transmission roller 41 has a blocking surface, and the locking member 102 has a blocked surface that can cooperate with the blocking surface. When the blocking surface and the blocked surface abut against each other, the transfer unit 04 enters a locked state. The specific structure of the blocking surface and the blocked surface can be a toothed end and a slot. The transmission roller 41 has a toothed end 0418, and the locking member 102 has a slot 1021 that can engage with the toothed end 0418. When the toothed end 0418 falls into the slot 1021, the transmission roller 41 cannot rotate around the rotating shaft 42, and the transfer unit 04 enters a locked state.

[0177] As shown in Figure 45, the positions of the tooth end and the slot can be interchanged. That is, the transmission roller 41 has a slot 1021, and the locking member 102 has a tooth end 0418 that can engage with the slot 1021. When the tooth end 0418 falls into the slot 1021, the transmission roller 41 cannot rotate around the rotating shaft 42, and the transfer unit 04 enters the locked state.

[0178] As shown in Figures 44 and 45, the drive unit 101 and the locking member 102 are separately arranged. The drive unit 101 has a drive ramp 1011, and the locking member 102 has an inclined action surface 1022 that can abut against the drive ramp 1011. Taking the direction shown in Figure 45 as an example, the drive ramp 1011 extends inclinedly from the direction of the cavity 3 towards the squeezing channel 11 from the inside out, and the inclined action surface 1022 has the same inclination direction. Under the action of the elastic reset member 103, the locking member 102 presses against the direction of the transfer unit 04. When an external force is applied to move the drive unit 101, the drive unit 101 moves to the side of the locking member 102. Under the action of the drive ramp 1011 and the inclined action surface 1022, the locking member 102 moves away from the transfer roller 41, that is, the locking member 102 moves away from the transfer unit 04, and the transfer unit 04 switches from the locked state to the active state. When an external force is applied to push the drive unit 101 in the opposite direction, the drive unit 101 moves away from the locking member 102. Under the restoring force of the elastic reset member 103, the locking member 102 moves towards the transmission roller 41, that is, the locking member 102 moves closer to the transfer unit 04, and the transfer unit 04 switches from the active state to the locked state.

[0179] In this embodiment, the locking member 102 is 7-shaped, with its slot 1021 or tooth tip 517 located in the longitudinal portion of the locking member 102, and its inclined action surface 1022 located in the transverse portion of the locking member 102. A portion of the driving part 101 extends from the top side wall of the cavity 3 or the squeezing frame 1. This arrangement provides a more reasonable spatial layout for the elastic reset member 103, the slot 1021, or the tooth tip 518, and the driving part 101 is conveniently positioned for operation, resulting in a more stable overall structure. Of course, the locking member 102 may also include only the longitudinal portion; no specific limitation is imposed.

[0180] The number of transmission rollers 41 is one or two or more, and they are arranged parallel to the pulling direction of the flat mop 9. In other words, two or more transmission rollers 41 are arranged vertically, and multiple transmission teeth 411 are evenly distributed around the outer wall of the transmission rollers 41, so as to evenly transmit the cleaning material to the wiping object and avoid uneven distribution of the cleaning material. Of course, in other embodiments, the number of transmission rollers 41 is not limited, and there can be one or more.

[0181] When there are two or more transfer rollers 41, at least two transfer rollers 41 are staggered, and the transfer roller 41 closer to the extruder 2 is closer to the squeezing channel 11 than the other transfer rollers 41. In other words, the transfer roller 41 closer to the extruder 2 is more biased towards the squeezing channel 11. This arrangement increases the contact pressure between the wiping material and the transfer roller 41, allowing the transfer roller 41 to rotate normally and transfer the cleaning material. It also avoids the situation where the transfer roller 41 closer to the extruder 2 cannot effectively contact the wiping material and thus cannot rotate due to deformation caused by the extruder 2.

[0182] The conveying roller 41 can be rotatably connected to the cavity 3 and facing the squeezing channel 11, or it can be rotatably connected to the squeezing frame 1 and facing the squeezing channel 11. The installation position of the conveying roller 41 is not limited, as long as it can rotate to realize the conveying of the clean body.

[0183] During use, initially, the transfer unit 04 is in a locked state, meaning the transfer roller 41 does not rotate. At this time, when the flat mop 9 is pulled up and down within the wringing channel 11 and pushed up and down relative to the squeezing member 2, the cleaning agent is not transferred to the object being wiped by the flat mop 9. When it is necessary to use the cleaning agent to clean the object being wiped by the flat mop 9, an external force is applied to the drive unit 101, causing the drive unit 101 to push the locking member 102 away from the transfer roller 41. The transfer unit 04 switches from the locked state to the active state, meaning the transfer roller 41 can rotate. At this time, when the flat mop 9 is in the wringing channel 11, the cleaning agent is not transferred to the object being wiped by the flat mop 9. When the wiping material is pulled up and down in the squeezing channel 11, it not only squeezes against the squeezing member 2, but also contacts and interacts with the transfer roller 41. That is, the transfer roller 41 rotates around the rotating shaft 42 under the drive of the wiping material, thereby transferring the cleaning body in the cavity 3 to the wiping material, so that the wiping material is cleaned by the cleaning body while being squeezed against the squeezing member 2. Once it is necessary to switch back to the locked state of the transfer unit 04, the external force applied to the drive unit 101 stops, and under the restoring force of the elastic reset member 103, the locking member 102 automatically moves towards the transfer roller 41.

[0184] The other structures are the same as in Embodiment 1, and will not be described again. Example 12

[0185] The difference between this embodiment and Embodiment Eleven is that the transfer unit 04 has a transfer ball as its conveying part, which is rolled within a circular hole located on the side wall of the cavity 3. There are multiple circular holes, and correspondingly multiple transfer balls, spaced apart on the same plane of the cavity 3. This ensures that all parts of the object being wiped can receive the cleaning material conveyed by the transfer balls. Of course, the multiple transfer balls may not be located on the same plane; there are no specific limitations. The outer wall of the transfer ball has grooves, which are the uneven structures used to acquire the cleaning material. When the transfer ball rolls, it can transfer the cleaning material from the cavity 3 to the object being wiped.

[0186] The locking unit 10 enables the transfer unit 04 to switch between the active state and the locked state. Specifically, the locking unit 10 may include locking rods that correspond one-to-one with the transfer ball. All locking rods are connected to the same panel. When an external force is applied, the panel is moved towards the direction of the transfer ball, so that the locking rods abut against the transfer ball, which can prevent the transfer ball from rotating in the circular hole. When an external force is applied in the opposite direction, the panel is moved away from the transfer ball, which can separate the locking rods from the transfer ball, allowing the transfer ball to rotate freely in the circular hole. Of course, the above-mentioned external force can also be achieved by an elastic reset member.

[0187] The other structures are the same as in Example 11, and will not be described again. Example 13

[0188] Based on Embodiment 10, the transfer unit 04 can adopt the transfer roller and scraper structure in Embodiment 5, and the cooperation of the locking member 72 and the biting tooth 73 can realize the switching between the transfer unit 04 in the active state and the locked state. Specifically, the locking member 72 moves relative to each other, so that it switches between two states: cooperating with the biting tooth 73 and cooperating with the avoidance part 74.

[0189] When an external force is applied to the dial 71, causing the locking member 72 to engage with the meshing teeth 73, the transfer roller 41 stops rotating under the action of the locking member 72. At this time, the transfer roller 41 cannot drive the locking member 72 to move up and down, meaning that there is no mutual friction or scraping action between the locking member 72 and the cleaning body, and the transfer unit 04 enters the locked state. The clearance part 74 has a groove structure. When an external force is applied in the opposite direction to the dial 71, causing the locking member 72 to disengage from the meshing teeth 73, and the locking member 72 enters the corresponding position of the clearance part 74, the meshing teeth on the locking member 72 are inside the clearance part 74, and they do not interact with the transfer roller 41. The transfer roller 41 can rotate freely, so the scraper 47 can move up and down to scrape the cleaning body under the drive of the transfer roller 41, and the transfer unit 04 enters the active state. Example 14

[0190] The transfer section is a mesh-like structure that at least partially covers the periphery of the clean body.

[0191] As shown in Figures 46-48, in this embodiment, the transfer part is an elastic foaming net made of elastic material and connected to the opening of the cavity 3 facing the squeezing channel 11. The cleaning body is a solid cleaning soap, which is placed inside the cavity 3, with its outer surface in contact with the elastic foaming net. At this time, the elastic foaming net can act as a textured structure to scrape the cleaning body, and under the up-and-down pulling and pushing of the wiping material of the flat mop 9, the cleaning body is easily adhered and foam is generated.

[0192] Compared to the transmission roller 41, transmission ball 43, transmission roller 41 and scraper 47 in the above embodiments, the elastic foaming net can be said to have no movement relative to the dewatering frame 1.

[0193] In this embodiment, the elastic foaming net partially covers the cleaning body, and the cavity 3 covers a portion of the cleaning body. In other words, the elastic foaming net and the cavity 3 together cover the cleaning body. Of course, in other embodiments, the elastic foaming net can completely cover the cleaning body and both can be placed inside the cavity 3, or the elastic foaming net that completely covers the cleaning body can be connected inside the cavity 3.

[0194] Of course, the transfer unit can also be a regular foaming net from existing products, which completely covers the cleaning body and is placed together in the cavity 3, or the foaming net that completely covers the cleaning body can be connected to the cavity 3. Alternatively, the foaming net can be connected to the opening of the cavity 3 facing the squeezing channel 11, partially covering the cleaning body.

[0195] Of course, the aforementioned blocking unit can also be disposed between the mesh and the wiping material in this embodiment. Example 15

[0196] A hands-free flat mop includes a flat mop 9 with a wiping agent, a mop handle 91 rotatably connected to the flat mop 9, and a squeezing device with any of the structures in Embodiments 1 to 14 described above.

[0197] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
