[0098] To enable those skilled in the art to better understand the solution of the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

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

[0100] The transfer portion can be in contact with 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 setting position of the transfer portion is not limited here first. It can be located between the cavity 3 and the water squeezing channel 11, or at least part of the transfer portion is located between the cavity 3 and the water squeezing channel 11.

[0101] The specific structure of the transfer portion is not limited here first either. It can be a structure that is stationary relative to the water squeezing frame 1, that is, the transfer portion does not move; it can also be a movable structure, that is, the transfer portion can move relative to the flat mop 9. The movement here includes rotation, includes translation, and includes a combination of rotation and translation; it can be a concave-convex structure or a smooth plane structure; as long as it can transfer the cleaning body to the flat mop 9 or more precisely to the wiping material of the flat mop 9.

[0102] The following will specifically describe the specific implementation structures of the transfer portion in multiple embodiments.

[0103] Embodiment 1

[0104] As Figures 1 - 9 shown, a squeezing device for a flat mop includes a water squeezing frame 1, a squeezing member 2, a cavity 3, and a transmission unit 4. In this embodiment, the transfer portion is arranged in the transmission unit 4.

[0105] The water squeezing frame 1 forms a water squeezing channel 11 for inserting the flat mop 9. Of course, it can also be that the water squeezing frame 1 and the cavity 3 are combined to form the water squeezing channel 11, which is not specifically limited. The flat mop 9 can be pulled, pushed, and drawn up and down inside the water squeezing channel 11, or in other words, the relative movement between the flat mop 9 and the water squeezing channel 11 realizes the up and down pulling, pushing, and drawing of the flat mop 9.

[0106] The setting position of the extrusion member 2 is not limited for the time being. It is used to extrude the wiping material of the flat mop 9 to achieve up-and-down pulling and pushing cleaning of the flat mop 9.

[0107] The cavity 3 is arranged on the water squeezing rack 1 and is used to store the cleaning body. The cleaning body is not limited either. It can be a liquid cleaning agent or a solid cleaning soap such as soap. The cavity 3 being arranged on the water squeezing rack 1 can be that the cavity 3 is arranged as an independent component inside the water squeezing rack 1, that is, the cavity 3 and the water squeezing rack 1 are separately arranged, or the cavity 3 and the water squeezing rack 1 are connected as a whole. The structure here also corresponds to the formation of the water squeezing channel 11. That is, when the water squeezing rack 1 and the cavity 3 are relatively independent, the water squeezing channel 11 is formed by the water squeezing rack 1, and when the water squeezing rack 1 and the cavity 3 are connected together, the water squeezing channel 11 is formed by the combination of the water squeezing rack 1 and the cavity 3. Of course, the cavity 3 may not be a relatively independent component, and it can generally be understood as the partial structure corresponding to storing the cleaning body.

[0108] At least part of the transmission unit 4 can act on the flat mop 9. The above-mentioned transmission unit 4 acting on the flat mop 9 can be that when the flat mop 9 is pulled and pushed up and down in the water squeezing channel 11, it drives at least part of the transmission unit 4 to move, or when the flat mop 9 is pulled and pushed up and down in the water squeezing channel 11, the two act together, and the specific situation is not limited. Thus, it is used to transfer the cleaning body in the cavity 3 to the wiping material of the flat mop 9. It at least has a transfer part that can rotate relative to the flat mop 9, and the transfer part has a concave-convex structure for obtaining the cleaning body. As Figure 7 shown, in this embodiment, the transfer part is the transmission roller 41, and transmission teeth 411 are evenly distributed on its outer wall. The transmission teeth 411 are the concave-convex structure for obtaining the cleaning body. The transmission roller 41 can rotate around the rotating shaft 42, so as to first transfer the cleaning body in the cavity 3 into the space between adjacent transmission teeth 411, and then transfer the cleaning body to the wiping material through the contact between the wiping material and the transmission teeth 411. By continuously rotating the transmission roller 41, the cleaning body in the cavity 3 is continuously conveyed to the wiping material.

[0109] 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, so as to transfer the cleaning body in the cavity 3 to the wiping material, enabling the flat mop 9 to perform in-depth cleaning of the cleaning body while being pulled and squeezed for cleaning in the water squeezing channel 11, making the cleaning effect of the flat mop 9 better. In the waiting state, the transmission unit 4 stops transferring the cleaning body to the wiping material. At this time, the flat mop 9 is pulled and squeezed for cleaning in the water squeezing channel 11 to complete the rinsing of the wiping material, avoiding the wiping material of the flat mop 9 still retaining a large amount of cleaning body when mopping the floor.

[0110] It should be noted that the at least part of the above-mentioned transmission unit 4 tending to contact the wiping object of the flat mop 9 means that it does not exclude the situation where the transmission unit 4 does not contact the wiping object of the flat mop 9, but the transmission unit 4 has made the cleaning body contact the wiping object. The at least part of the above-mentioned transmission unit 4 refers to the situations including the whole of the transmission unit 4 contacting the wiping object, only a small part of the transmission unit 4 contacting the wiping object, and the vast majority of the transmission unit 4 contacting the wiping object.

[0111] Regarding the switching of the transmission unit 4 between the working state and the waiting state, it can be achieved by changing the relative positions of at least part of the transmission unit 4 and the water squeezing rack 1. Or rather, it is by changing the relative positions of at least part of the cavity 3 and at least part of the transmission unit 4. It should be noted that at least part of the cavity 3 here includes the cleaning body in the cavity 3.

[0112] Specifically, the transmission unit 4 and the cavity 3 are movably connected to the water squeezing rack 1. As a whole, the transmission unit 4 and the cavity 3 can move relative to the water squeezing rack 1, which can be a translational movement or a non-linear movement, so as to realize the switching between the working state and the waiting state of the transmission unit 4 (the specific structure will be elaborated in Embodiments 1, 3, and 4). It should be noted that the translational movement here does not refer to horizontal movement, but linear movement, which can be translational movement in the horizontal direction, vertical direction, or inclined direction, and there is no specific limitation (the translational movement described below is interpreted in this way). Alternatively, the transmission unit 4 can be rotatably connected to the water squeezing rack 1, which 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 water squeezing rack 1, so that the transmission unit 4 rotates to the side of the water squeezing rack 1 facing the water squeezing channel 11, or the transmission unit 4 can be rotated to the side away from the water squeezing channel 11, so as to realize the switching between the working state and the waiting state of the transmission unit 4 (the specific structure will be elaborated in Embodiment 7). Or, at least part of the cavity 3 can move relative to the water squeezing rack 1, so that the relative position between at least part of the transmission unit 4 and the cleaning body changes, so as to realize the switching between the working state and the waiting state of the transmission unit 4 (the specific structure will be elaborated in Embodiment 6). It should be noted that at least part of the cavity 3 here can be the cavity 3 itself, or can include the cleaning body in the cavity 3. Or, the transmission unit 4 can be movably connected to the water squeezing rack 1, and at least part of the transmission unit 4 can move relative to the water squeezing rack 1, which can be a translational movement or a non-linear movement, so that the transmission unit 4 approaches the cleaning body in the cavity 3 and scrapes the cleaning body to convey to the wiping object, so as to realize the switching between the working state and the waiting state of the transmission unit 4 (the specific structure will be elaborated in Embodiment 5). Or, the transmission unit 4 can be movably connected to the water squeezing rack 1, and at least part of the transmission unit 4 can move relative to the water squeezing rack 1, which can be a translational movement or a non-linear movement, so that the transmission unit 4 approaches or moves away from the water squeezing channel 11, so as to realize the switching between the working state and the waiting state of the transmission unit 4.

[0113] Specifically expanding to the structure of this embodiment, as Figure 4 、 Figure 7 shown, the extrusion member 2 is fixedly arranged on the side of the water squeezing rack 1 facing the water squeezing channel 11. Of course, the extrusion member 2 can also be movably connected to the water squeezing rack 1, and there is no specific limitation. The cavity 3 is movably arranged on the water squeezing rack 1. One side of the cavity 3 is open, and the transmission unit 4 is connected to the open side of the cavity 3, specifically arranged on the side of the cavity 3 facing the water squeezing channel 11. Under the drive of an external force, the cavity 3 can move relative to the water squeezing rack 1, so that the transmission unit 4 switches between the working state and the waiting state. Taking Figure 3 、 Figure 4Taking the direction shown as an example, the cavity 3 can move left and right relative to the water squeezing rack 1. When the cavity 3 moves to the right, the transmission unit 4 is closer to the wiping object 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 is away from the wiping object of the flat mop 9, causing the transmission unit 4 to enter the waiting state.

[0114] Taking Figure 3 、 Figure 4 shown as an example, at this time the transmission unit 4 is in the waiting state, and it is located on the side of the squeezing member 2 away from the water squeezing channel 11, that is, the transmission unit 4 is located on the left side of the squeezing member 2. When the flat mop 9 is pulled in the water squeezing channel 11, only the squeezing member 2 plays a role, and the transmission unit 4 will not transmit the cleaning body to the wiping object. When the transmission unit 4 enters the working state, the transmission unit 4 moves to the right and is flush with the squeezing member 2. When the flat mop 9 is pulled in the water squeezing channel 11, the squeezing member 2 plays a role, and at the same time the transmission unit 4 transmits the cleaning body to the wiping object.

[0115] More specifically, as Figures 7 - 9 shown, in this embodiment, the transmission unit 4 includes transmission rollers 41 rotatably connected to the cavity 3. The number of them is two and they are arranged in parallel along the pulling direction of the flat mop 9. In other words, the two transmission rollers 41 are arranged vertically, and a plurality of transmission teeth 411 are evenly spaced around the outer wall of the transmission roller 41, so that the cleaning body can be evenly transmitted to the wiping object, avoiding uneven distribution of the cleaning body. Of course, in other embodiments, the number of the transmission rollers 41 is not limited, and it can be one or more.

[0116] For the convenience of assembly, the side wall of the cavity 3 forms an elastic mounting side wall structure, and a rotating shaft 42 is formed inside the elastic mounting side wall. 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 driving of 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, drives it outwards after rotation, and rotates in the same direction continuously, realizing the continuous transmission of the cleaning body.

[0117] For the convenience of assembly and relatively stable structure after assembly, the water squeezing rack 1 is divided into upper and lower frame layers. The squeezing member 2 is fixedly connected to the upper frame layer of the water squeezing rack 1, the cavity 3 is movably connected to the lower frame layer, and both the cavity 3 and the squeezing member 2 extend in the entire width direction of the water squeezing rack 1.

[0118] In the present embodiment, the driving component 6 drives the chamber 3 to translate, and at least a part of the driving component 6 translates or rotates to drive the chamber 3 to translate relative to the water squeezing frame 1. Specifically, in the present embodiment, the driving component 6 at least includes a shifting transverse groove 12 provided on the water squeezing frame 1, a shifting member 61 movably connected to the water squeezing frame 1, and a movable track 62 provided on the chamber 3. The shifting transverse groove 12 extends along the width direction of the water squeezing frame 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 transverse groove 12. By applying an external force to drive the shifting member 61 to move in the shifting transverse groove 12 relative to the water squeezing frame 1, the chamber 3 can be extended or retracted into the water squeezing frame 1.

[0119] like Figure 10 , Figure 11 As shown, part of the toggle member 61 passes through the top of the water squeezing frame 1 and the toggle transverse groove 12, and part of the toggle member 61 passes through the extrusion member 2 and then cooperates with the movable track 62. In this embodiment, there are two movable tracks 62, and correspondingly, two slide rail structures 21 are also provided at corresponding positions on the extrusion member 2, and two toggle parts 611 that can extend into the movable track 62 are provided on the toggle member 61.

[0120] like Figure 9 As shown, the movable track 62 includes a slide groove 1 621, a slide groove 2 622 arranged parallel to the slide groove 1 621, and a transition slide groove 623 connecting the slide groove 1 621 and the slide groove 2 622. The transition slide groove 623 is arranged obliquely. Of course, the slide groove 1 621 and the slide groove 2 622 are not necessarily completely parallel, as long as they are not located in the same straight line. Specifically, the slide groove 1 621 extends along the width direction of the cavity 3, and the entire movable track 62 is a Z-shaped slide groove. Here, the Z-shaped slide groove refers to a shape trend close to the Z shape, which is not necessarily a standard Z shape, but can also be a mirror image of Z. The slide groove 1 and the slide groove 2, and the transition slide groove are not necessarily straight grooves, but can also be curved grooves. As long as the slide groove 1 621 and the slide groove 2 622 have a height difference and are connected to each other, the specific shape is not limited.

[0121] When external force is applied to make the toggle member 61 translate relative to the water squeezing rack 1 in the toggle transverse groove 12, due to the restriction of the toggle transverse groove 12, the two toggle parts 611 of the toggle member 61 can only translate laterally. Once it translates to a width exceeding the lateral width of the slide groove 1 621 or the slide groove 2 622, it will inevitably enter the transition slide groove 623. Since the toggle part 611 can only translate, the toggle part 611 moves against the transition slide groove 623, and the cavity 3 translates inward and outward under the drive of the toggle part 611.

[0122] In order to ensure that the transmission unit 4 can stably stay in the working state or the waiting state, a positioning component 7 for limiting the transmission unit 4 in the working state or the waiting state is also included.Figure 5 , Figure 6 As shown in Figure 6 , the positioning component 7 is in limit cooperation with the driving component 6. Specifically, the positioning component 7 is a rib structure provided on the water squeezing frame 1, and this rib can abut against the toggling member 61 of the driving component 6, so that the toggling member 61 stays at this position, and only by applying a greater external force can the toggling member 61 cross the rib and switch to another state. The number of ribs is at least one, and it can cooperate with two grooves, so that the toggling member 61 can stay when the transmission unit 4 is in the working state or in the waiting state. Of course, in other embodiments, it can also be other limit structures in the prior art, and specific limitations are not made.

[0123] Of course, the structure can be simplified. The driving component 6 can also include a longitudinal groove structure opened on the water squeezing frame 1 and a toggling member connected to the cavity 3. When an external force is applied to drive the toggling member to translate in the longitudinal groove, the cavity 3 is driven to move synchronously closer to or farther away from the water squeezing channel 11, achieving the purpose of driving the transmission unit 4 to approach or move away from the water squeezing channel 11, so that the transmission unit 4 switches between the working state and the waiting state.

[0124] When the cleaning body in the cavity 3 is a solid cleaning soap, after long-term use, the volume of the fixed cleaning soap becomes smaller. In order to enable it to always be in effective contact with the transmission unit 4, the squeezing device can further include a pressing unit 8, and the pressing unit 8 presses the solid cleaning soap toward the side where the transmission unit 4 is located. Specifically, the pressing unit 9 at least includes a pressing plate 81 in contact with the cleaning body and an elastic member abutting against the pressing plate 81, and the other end of the elastic member abuts against the side wall of the cavity 3. As the volume of the cleaning body in the cavity 3 deforms, the compressed elastic member 82 continuously elongates, and the cleaning body is pushed toward the transmission unit 4 by the pressing plate 81.

[0125] A hands-free flat mop includes a flat mop 9 with a wiping material, a mop rod 91 rotatably connected to the flat mop 9, and the squeezing device with the above structure.

[0126] 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 extrusion member 2 away from the water squeezing channel 11. At this time, when the flat mop 9 is pulled up and down in the water squeezing channel 11 and pushed up and down relative to the extrusion member 2, the cleaning body will not be transmitted to the wiped object of the flat mop 9; when the cleaning body is needed to clean the wiped object of the flat mop 9, an external force is applied to the toggle member 61, so that the toggle member 61 is translated in the toggle transverse groove 12, and the toggle part 611 moves in the movable track 62, specifically, the toggle part 611 enters the slide groove 1 621 from the second slide groove 622 through the transition slide groove 623, so that the cavity 3 moves relative to the squeezing frame 1 in the direction close to the squeezing channel 11; at this time, when the flat mop 9 is pulled and pushed up and down in the squeezing channel 11, the wiping material is not only squeezed by the squeezing member 2, but also contacts and interacts with the transmission roller 41, that is, the transmission roller 41 rotates around the rotating shaft 42 driven by the wiping material, thereby transmitting 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 by the squeezing member 2; due to the limited cooperation between the positioning component 7 and the driving component 6, the toggle portion 61 can stably stay in the slide groove 1 621, that is, the transmission roller 41 on the cavity 3 is kept in the state of extending out of the squeezing frame 1.

[0127] Embodiment 2

[0128] like Figures 12 - 14 As shown, the difference between this embodiment and the first embodiment is that the transfer part is a transmission ball 43, which is rolled in a circular hole 431, and the circular hole 431 is provided on the side wall of the cavity 3. There are multiple circular holes 431, and the corresponding number of transmission balls 43 is also multiple, which are arranged at intervals on the same plane of the cavity 3, so that all parts of the wiping object can receive the cleaning body transported by the transmission ball 43. Of course, the multiple transmission balls 43 may not be located in the same plane, and there is no specific limitation. The outer wall of the transmission ball 43 is distributed with grooves 432, which are concave-convex structures for obtaining the cleaning body. When the transmission ball 43 rolls, the cleaning body in the cavity 3 can be transferred to the wiping object.

[0129] The other structures are the same as those in the first embodiment and will not be described in detail.

[0130] Embodiment 3

[0131] The difference between this embodiment and the first embodiment is that at least part of the driving assembly 6 rotates, thereby driving the receiving chamber 3 to translate relative to the squeezing rack 1 .

[0132] like Figures 15 - 20 As shown, the driving assembly 6 includes a driving wheel 63 , an external thread segment 631 extending vertically from the center of the driving wheel 63 , and an internal thread portion 31 disposed in the cavity 3 .

[0133] Specifically, the water squeezing rack 1 and the cavity 3 are relatively independent. The driving wheel 63 is rotatably connected to the water squeezing rack 1, and a part of the driving wheel 63 protrudes from the surface of the water squeezing rack 1. A flat plate is connected to the outer wall of the cavity 3. The flat plate forms a notch part for supporting the external thread section 631, and an internal thread part 31 is formed on the inner wall of the notch part.

[0134] Apply an external force to rotate the driving wheel 63. The external thread section 631 and the internal thread part 31 cooperate to drive the cavity 3 to move. For example, when the driving wheel 63 rotates forward, the cavity 3 moves away from the water squeezing channel 11, so that the wiping object can only contact the squeezing member 2, but cannot contact the cleaning body of the transmission unit 4, or rather, cannot contact the transmission sphere 43, making the transmission sphere 43 unable to rotate to continuously convey the cleaning body in the cavity 3 to the wiping object. At this time, the transmission unit 4 enters the waiting state; when the driving wheel 63 rotates backward, the cavity 3 moves closer to the water squeezing channel 11, and at this time the transmission unit 4 enters the working state.

[0135] Embodiment 4

[0136] In this embodiment, at least part of the driving component 6 rotates, thereby driving the cavity 3 to translate relative to the water squeezing rack 1.

[0137] As Figures 21 - 26 shown, the driving component 6 includes a rotating wheel 64, a driving column 641 eccentrically arranged on the rotating wheel 64, and a transverse groove body 32 arranged in the cavity 3. Specifically, the water squeezing rack 1 and the cavity 3 are relatively independent. The rotating wheel 64 is rotatably connected to the water squeezing rack 1, and the driving column 641 is stuck in the transverse groove body 32, that is, the outer diameter of the driving column 641 is approximately equal to the width of the transverse groove body 32.

[0138] Apply an external force to rotate the rotating wheel 64. The driving column 641 can move in the transverse groove body 32, thereby driving the cavity 3 to move. For example, when the rotating wheel 64 rotates clockwise, the cavity 3 moves away from the water squeezing channel 11, so that the wiping object can only contact the squeezing member 2, but cannot contact the cleaning body of the transmission unit 4, or rather, cannot contact the transmission sphere 43, making the transmission sphere 43 unable to rotate to continuously convey the cleaning body in the cavity 3 to the wiping object. 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 water squeezing channel 11, and at this time the transmission unit 4 enters the working state.

[0139] In order to limit the transmission unit 4 in the working state or the waiting state, as Figure 26 shown, a limiting convex rib 642 is arranged on the rotating wheel 64, as Figure 23As shown, a limit groove 13 is provided on the water squeezing rack 1. When the limit convex rib 642 falls into the limit groove 13, the transmission unit 4 is limited to the working state. Similarly, another limit groove (not shown in the figure) can also be provided on the cavity 3. When the limit convex rib 642 falls into the limit groove 13 of the cavity 3, the transmission unit 4 is limited to the waiting state.

[0140] Embodiment Five

[0141] The difference between this embodiment and Embodiment One lies in the different structure of the transmission unit 4.

[0142] As Figures 27 - 30 shown, the transmission unit 4 includes a transmission roller 41 and a scraping member 47. Both the above-mentioned transmission roller 41 and the scraping member 47 are arranged towards the water squeezing channel 11. Relatively speaking, the transmission roller 41 is located above the scraping member 47. When the flat mop 9 is pulled up and down and pushed, it can drive the transmission roller 41 to rotate. While the transmission roller 41 is rotating, it drives the scraping member 47 to move, so that the scraping member 47 moves to scrape the cleaning body.

[0143] As Figure 29 shown, in this embodiment, the transmission roller 41 is a driving roller, which is rotatably connected to the water squeezing rack 1 and can contact the wiping object of the flat mop 9 and rotate relative to its own rotating shaft 462 under the drive of the wiping object. An eccentric crank portion 461 is also connected to the driving roller, that is, the center line of the crank portion 461 does not overlap with the center line of the rotating shaft 462.

[0144] As Figure 30 shown, the scraping member 47 is a scraping member for scraping the cleaning body. The scraping member is connected with 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 driving roller rotates relative to the water squeezing rack 1, the crank portion 461 moves up and down in the movable groove 471, thereby driving the scraping member to move up and down. In this embodiment, the cleaning body is a solid cleaning soap, and the solid cleaning soap can be scraped during the upward or downward movement of the scraping member and transmitted to the wiping object. In other words, at this time, the transmission roller 512 may not play the role of scraping the cleaning body, and of course, it does not exclude that the transmission roller 512 and the scraping member 47 play the role of scraping the cleaning body at the same time.

[0145] When the transmission roller 41 rotates relative to drive the scraping member 47 to move up and down, the transmission unit 4 enters the working state. When the transmission roller 41 stops rotating relative to each other, it cannot drive the scraping member 47 to move up and down. At this time, the transmission unit 4 enters the waiting state.

[0146] In this embodiment, the specific structure of the positioning assembly 7 for limiting the transmission unit 4 in the working state or the waiting state includes a dial button 71 partially extending from the surface of the extrusion device, a locking member 72 connected to the dial button 71, and a meshing tooth portion 73 and an escape portion 74 located on the outer wall of the driving roller. The locking member 72 can move relatively so that it switches between two states of cooperating with the meshing tooth portion 73 and cooperating with the escape portion 74.

[0147] When an external force is applied to the dial button 71 so that the locking member 72 meshes with the meshing tooth portion 73, the driving roller stops rotating under the action of the locking member 72. At this time, the driving roller cannot drive the scraper to move up and down, that is, there is no mutual friction and scraping action between the scraper and the cleaning body, and the transmission unit 4 enters a waiting state. The avoidance portion 74 is a groove structure. When an external force is applied to the dial button 71 in the reverse direction so that the locking member 72 is disengaged from the meshing tooth portion 73, and the locking member 72 enters the relative position corresponding to the avoidance portion 74, the meshing teeth on the locking member 72 are in the avoidance portion 74, and will not interact with the driving roller. The driving roller can rotate freely, so that the scraper can move up and down (here up and down is represented by "up and down") driven by the driving roller. Figure 28 The direction shown is used as an example) to scrape and clean the body, and the transmission generates 4 to enter the working state.

[0148] Another function of the meshing teeth 73 is to better transmit the force of the wipe to the drive roller, so that the drive roller can rotate around its own rotation axis 462. In this structure, the drive roller and the scraper can be understood as the transfer part of the transmission unit 4. The scraper can be understood as the concave-convex structure on the transfer part. Specifically, in this embodiment, the scraper can be a grid-like structure, and the cleaning body is transmitted from the gap to the wipe.

[0149] In this embodiment, the squeezing rack 1 and the receiving chamber 3 are connected together, that is, the receiving chamber 3 is not an independent component, and can be generally understood as a partial structure corresponding to the storage of the cleaning body.

[0150] Embodiment 6

[0151] The difference between this embodiment and the first embodiment is that the structure of the transmission unit 4 is different.

[0152] like Figures 31 - 34 As shown, the transmission unit 4 includes a first part 44 and a second part 45. The first part 44 is arranged toward the water squeezing channel 11, and the second part 45 is opposite to the first part 44, and the two are respectively located on both sides of the cleaning body. The cleaning body in the cavity 3 can move relative to the water squeezing frame 1 under the drive of the second part 45, so that the cleaning body contacts or moves 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.

[0153] The structure of the first part 44 is similar to that of the first embodiment. It is a transmission roller structure, which is rotatably connected to the water squeezing frame 1 or the cavity 3. Details are not described herein again. In this embodiment, the water squeezing frame 1 and the cavity 3 are connected together. That is to say, the cavity 3 is not an independent component. It can generally be understood as the part of the structure corresponding to storing the cleaning body, and there is no clear dividing line between it and the water squeezing frame 1.

[0154] The second part 45 includes a lifting member one 451 and a lifting member two 452 rotatably connected to the cavity 3 or the water squeezing frame 1, a movable member one 453 connected to the lifting member one 451, a movable member two 454 connected to the lifting member two 452, and a force applying member 455. The lifting member one 451 and the lifting member two 452 extend in the entire width direction of the extrusion device and are generally rod-shaped. The key is that lifting sliders 450 are provided on both the lifting member one 451 and the lifting member two 452, and an extension arm 459 is also connected to the lifting member one 451.

[0155] The number of the movable members one 453 is at least two, which are respectively located at both ends of the lifting member one 451 and are connected to the lifting member one 451 at an angle. Similarly, the number of the movable members two 454 is also at least two, which are respectively located at both ends of the lifting member two 452 and are connected to the lifting member two 452 at an angle. Vertical sliding columns 456 are provided on the movable members one 453, and track grooves 457 are provided on the movable members two 454. After assembly, the sliding columns 456 fall into the track grooves 457.

[0156] As Figure 34 shown, the force applying member 455 has an arc-shaped sliding rail 458. When an external force is applied to make the force applying member 455 translate relative to the extrusion device, the arc-shaped sliding rail 458 drives the extension arm 459 to move, so that the lifting member one 451 rotates, driving the lifting slider 450 to rotate. At this time, the sliding column 456 moves in the track groove 457, and the lifting slider 450 on the lifting member two 452 also rotates. Therefore, the lifting sliders 450 on the lifting member one 451 and the lifting member two 452 cooperate with each other to lift the cleaning body away from the first part 44, and at this time the transmission unit 4 enters the waiting state; or the lifting sliders 450 on the lifting member one 451 and the lifting member two 452 cooperate with each other to move the cleaning body close to the first part 44, and at this time the transmission unit 4 enters the working state.

[0157] The positioning component 7 in this embodiment can be a card slot structure provided at both ends of the arc-shaped sliding rail 458. It is equivalent to the positioning component 7 being in limit cooperation with the transmission unit 4, and specific limitations are not made.

[0158] Embodiment Seven

[0159] As Figure 35 、 Figure 36As shown, in this embodiment, the transmission unit 4 and the extrusion member 2 are both provided on the cavity 3, and the cavity 3 is rotatably connected to the water squeezing frame 1, and a water squeezing channel 11 is formed between the water squeezing frame 1 and the cavity 3.

[0160] Applying an external force to the knob 13 can cause the cavity 3 to rotate relative to the water squeezing frame 1. When the extrusion member 2 rotates to face the side of the water squeezing channel 11, the transmission unit 4 is located on the side away from the water squeezing channel 11. When the transmission unit 4 faces the side of the water squeezing channel 11, the extrusion member 2 is located on the side away from the water squeezing channel 11. Of course, in other embodiments, the transmission unit 4 can also be located on the upper side, that is, the side where the transmission unit 4 is located forms a 90° angle with the side where the extrusion member 2 is located. In other words, the extrusion member 2 and the transmission unit 4 will not be in the working state at the same time. When the extrusion member 2 squeezes the wiping material, the transmission unit 4 enters the waiting state. When the transmission unit 4 enters the working state, the extrusion member 2 is in a non-use state. By rotating the cavity 3 together with the extrusion member 2 and the transmission unit 4 relative to the water squeezing frame 1, the transmission unit 4 can be switched between the working state and the waiting state.

[0161] The specific structure of the transmission unit 4 is similar to that of the first embodiment and will not be described in detail.

[0162] Embodiment Eight

[0163] As Figures 37 - 39 shown, the extrusion member 2 and the cavity 3 are relatively fixed on the water squeezing frame 1. The transmission unit 4 is located on the side of the cavity 3 facing the water squeezing channel 11, and the extrusion member 2 also faces the water squeezing channel 11. The extrusion member 2 and the transmission unit 4 are arranged vertically and can simultaneously squeeze the wiping material of the flat mop 9. Relatively speaking, the extrusion member 2 is slightly closer to the water squeezing channel 11, and the transmission unit 4 is slightly farther away from the water squeezing channel 11. A blocking unit 5 is also provided on the water squeezing frame 1. The blocking unit 5 can move through the extrusion member 2 to the opposite side of the transmission unit 4. In other words, the blocking unit 5 can move through the extrusion member 2 to between the wiping material and the transfer part of the transmission unit 4, so as to isolate the transmission unit 4 and the wiping material. Of course, the blocking unit 5 may not pass through the extrusion member 2, but pass out between the extrusion member 2 and the transfer part, or the blocking unit 5 moves to between the wiping material and the transfer part, or the blocking unit 5 moves to between the cleaning body and the transfer part. There is no specific limitation, and its ultimate purpose is to isolate the transfer part of the transmission unit 4 and the wiping material.

[0164] Of course, the squeezing member 2 can also be fixedly connected to the water squeezing frame 1, and the blocking unit 5 moves from below the squeezing member 2 to the opposite side of the transmission unit 4, so that the transfer part and the wiping object are isolated. Or, the squeezing member 2 is fixedly connected to the water squeezing frame 1, and there is a gap between the squeezing member 2 and the water squeezing frame 1, and the blocking unit 5 can move through the gap to the opposite side of the transfer part. In the above structure, the blocking unit 5 moves downwards to the opposite side of the transmission unit 4. In other embodiments, the blocking unit 5 can move from the side of the transmission unit 4 to the exact opposite side of the transmission unit 4, and there is no specific limitation. The blocking unit 5 can be a plate-like structure that can undergo a certain deformation but has a certain stiffness, and there is no specific limitation.

[0165] Of course, the above squeezing member 2 can also be movably connected to the water squeezing frame 1, and there is no specific limitation.

[0166] During use, when only the squeezing member 2 is needed, the blocking unit 5 is moved to the opposite side of the transmission unit 4, so that the cleaning body in the cavity 3 will not be transmitted to the wiping object of the flat mop 9 through the transmission unit 4. At this time, the transmission unit 4 enters the waiting state; when the cleaning body is needed, the blocking unit 5 is moved back, so that both the transmission unit 4 and the squeezing member 2 can contact the wiping object of the flat mop 9. At this time, the transmission unit 4 enters the working state.

[0167] Of course, the above blocking unit can also be arranged between the transfer part of the transfer unit 04 in Embodiment Eleven and the wiping object.

[0168] Embodiment Nine

[0169] In this embodiment, different from Embodiment One, the cavity 3 and the squeezing member 2 are respectively movably connected to the water squeezing frame 1, and the transmission unit 4 is arranged on the side of the cavity 3 facing the water squeezing channel 11. Under the action of an external force, the relative movement between the cavity 3 and the water squeezing frame 1 and the relative movement between the squeezing member 2 and the water squeezing frame 1 can be respectively realized.

[0170] When it is necessary to squeeze the squeezing member 2 against the wiping object, the squeezing member 2 is moved out relative to the water squeezing frame 1. At this time, the transmission unit 4 can retract into the water squeezing frame 1, that is, only the squeezing member 2 squeezes against the wiping object in the water squeezing channel 11; when it is necessary for the transmission unit 4 to contact the wiping object, the transmission unit 4 is moved out relative to the water squeezing frame 1. At this time, the squeezing member 2 can retract into the water squeezing frame 1, that is, only the transmission unit 4 contacts the wiping object in the water squeezing channel 11; or, both the squeezing member 2 and the transmission unit 4 are moved out relative to the water squeezing frame 1, so that when the flat mop 9 is pulled up and down in the water squeezing channel 11, both the squeezing member 2 and the transmission unit 4 can play a role.

[0171] The structure of the transmission unit 4 is the same as that in Embodiment One, and the structure for driving the relative movement of the cavity 3 and the squeezing member 2 relative to the water squeezing frame 1 can also be similar to that in Embodiment One, and will not be elaborated here.

[0172] Embodiment Ten

[0173] In this embodiment, at least a part of the driving component 6 undergoes translation and rotation, thereby driving the cavity 3 to move relative to the water squeezing rack 1, so that the cavity 3 approaches or moves away from the water squeezing channel 11.

[0174] Specifically, the driving component 6 includes a dial with a straight tooth section, a gear meshing with the straight tooth section of the dial, and a movable part with a straight tooth section. The straight tooth section of the movable part also meshes with the dial. At the same time, the movable part is connected to the cavity 3. Thus, when an external force is applied to the dial to make it translate, the straight tooth section of the dial will drive the gear to rotate, and then drive the movable part to move, so that the cavity 3 approaches or moves away from the water squeezing channel 11.

[0175] Other structures are the same as those in Embodiment One and will not be elaborated here.

[0176] Embodiment Eleven

[0177] As Figures 40 - 45 shown, a flat mop squeezing device includes a water squeezing rack 1, a water squeezing channel 11, a squeezing member 2, a cavity 3, and a transfer unit 04. In this embodiment, the transfer part is arranged on the transfer unit 04.

[0178] In this embodiment, the cleaning body is a solid cleaning soap. Of course, the cavity 3 may not be a relatively independent component, and it can generally be understood as the partial structure corresponding to storing the cleaning body.

[0179] The squeezing member 2 is located in the water squeezing channel 11. Specifically, it can be fixedly connected to the side of the water squeezing rack 1 facing the water squeezing channel 11, or movably connected to the side of the water squeezing rack 1 facing the water squeezing channel 11; alternatively, the squeezing member 2 is fixedly connected to the side of the cavity 3 facing the water squeezing channel 11, or movably connected to the side of the cavity 3 facing the water squeezing channel 11. The squeezing member 2 is used to squeeze the wiping object of the flat mop 9 to achieve up-and-down pulling, pushing, and squeezing cleaning of the flat mop 9.

[0180] At least a part of the transfer unit 04 can act on the flat mop 9, so that at least a part of the transfer unit 04 moves. The above-mentioned transfer unit 04 and the flat mop 9 acting on each other can be that when the flat mop 9 is pulled, pushed, and squeezed up and down in the water squeezing channel 11, it drives at least a part of the transfer unit 04 to move, or when the flat mop 9 is pulled, pushed, and squeezed up and down in the water squeezing channel 11, the flat mop 9 and at least a part of the transfer unit 04 act together. Specifically, there is no limitation, so as to be used to transfer the cleaning body in the cavity 3 to the wiping object of the flat mop 9.

[0181] The transfer unit 04 at least has a transfer part that can rotate relative to the flat mop 9, and the transfer part has a concave-convex structure for obtaining the cleaning body. As Figure 43As shown, in this embodiment, the transfer part is the transfer roller 41, and the outer wall of the transfer roller 41 is evenly distributed with transfer teeth 411. The transfer teeth 411 are the concave-convex structures for obtaining 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 continuously rotating the transfer roller 41, the cleaning body in the cavity 3 is continuously conveyed to the wiping object. Of course, it is not excluded that the transfer part of the transfer unit 04 has no concave-convex structure. A smooth plane as the transfer part can also achieve the transfer of the cleaning body. In addition, the concave-convex structure here also includes structures with relatively small concavities and convexities such as rough surfaces.

[0182] The transfer unit 04 has at least an active state and a locked state. In the active state, at least part of the transfer unit 04 moves, so as to convey the cleaning body in the cavity 3 to the wiping object, so that when the flat mop 9 is pulled and squeezed in the water squeezing channel 11 for cleaning, the deep cleaning of the cleaning body is carried out at the same time, making the cleaning effect of the flat mop 9 better. In combination with the specific structure of this embodiment, the transfer roller 41 rotates around the rotating shaft 42, so that the transfer teeth 411 continuously scrape the cleaning body in the cavity 3 and rotate and convey it to the side of the water squeezing channel 11, so that the flat mop 9 can effectively adhere to the cleaning body between the transfer teeth 411 when being pulled and cleaned in the water squeezing channel 11.

[0183] In the locked state, the transfer unit 04 stops moving, so that the conveyance of the cleaning body in the cavity 3 to the wiping object stops. At this time, the flat mop 9 is pulled and squeezed in the water squeezing channel 11 for cleaning, and the rinsing of the wiping object is completed, avoiding that there are still a large number of cleaning bodies remaining on the wiping object when the flat mop 9 is mopping the floor. In combination with the specific structure of this embodiment, the transfer roller 41 stops rotating. Even if the transfer teeth 411 facing the cavity 3 scrape the cleaning body, they cannot rotate and convey it to the side of the water squeezing channel 11. When the flat mop 9 is pulled in the water squeezing channel 11, it cannot adhere to the cleaning body.

[0184] For the switching of the transfer unit 04 between the active state and the locked state, the locking unit 10 is utilized. The locking unit 10 includes a driving part 101, a locking part 102 cooperating with the driving part 101, and an elastic reset part 103. The elastic reset part 103 abuts against the locking part 102, the water squeezing frame 1 or the cavity 3 respectively, and is used to press the locking part 102 towards the direction where the transfer unit 04 is located. Specifically, when the water squeezing frame 1 and the cavity 3 are joined to form a water squeezing channel 11, one end of the elastic reset part 103 abuts against the cavity 3, the driving part 101 can be connected to the cavity 3, and the driving part 101 can translate relative to the cavity 3; when the water squeezing frame 1 forms the water squeezing channel 11, one end of the elastic reset part 103 abuts against the cavity 3 or the water squeezing frame 1, the driving part 101 can be connected to the water squeezing frame 1, and the driving part 101 can translate relative to the water squeezing frame 1. The above-mentioned driving part 101 and the locking part 102 cooperate, and they can be integrally connected or separately arranged.

[0185] When an external force is applied to the driving part 101, the locking part 102 can abut against the transfer unit 04, so that the transfer unit 04 switches from the active state to the locked state. At this time, the elastic reset part 103 may not be set. By applying an opposite external force to the driving part 101, the transfer unit 04 switches from the locked state to the active state, that is, at this time the locking unit 10 includes the driving part 101 and the locking part 102, and the two can be integrally arranged. Of course, an elastic reset part can also be set, and the force acting on the driving part 101 is a force that makes the locking part 102 move away from the transfer unit 04.

[0186] Or, when an external force is applied to the driving part 101, the locking part 102 can be separated from the state of abutting against the transfer unit 04, so that the transfer unit 04 switches from the locked state to the active state. At this time, the elastic reset part 103 is provided. When the external force applied to the driving part 101 is stopped, under the action of the elastic reset part 103, the locking part 102 can abut against the transfer unit 04, that is, the transfer unit 04 switches from the active state to the locked state.

[0187] As Figure 44 shown, for the structure where the locking part 102 abuts against the transfer unit 04, the transmission roller 41 has a blocking surface, and the locking part 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 the locked state. The specific structures of the blocking surface and the blocked surface can be a tooth end and a card slot. The transmission roller 41 has a tooth end 0418, and the locking part 102 has a card slot 1021 that can engage with the tooth end 0418. When the tooth end 0418 falls into the card slot 1021, the transmission roller 41 cannot rotate around the rotating shaft 42, and the transfer unit 04 enters the locked state.

[0188] As Figure 45As shown, 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 element 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 a locked state.

[0189] like Figure 44 , Figure 45 As shown, the driving part 101 and the locking element 102 are separately arranged, the driving part 101 has a driving inclined surface 1011, and the locking element 102 has an inclined action surface 1022 that can abut against the driving inclined surface 1011. Figure 45 Taking the direction shown as an example, the driving inclined surface 1011 extends obliquely from the direction of the chamber 3 to the direction of the water squeezing channel 11 and from the inside to the outside, and the inclined direction of the inclined action surface 1022 is the same. Under the action of the elastic reset member 103, the lock member 102 presses in the direction of the transfer unit 04. When an external force is applied to the drive unit 101, the drive unit 101 translates to the side of the lock member 102. Under the action of the driving inclined surface 1011 and the inclined action surface 1022, the lock member 102 moves away from the transmission roller 41, that is, the lock 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 the drive unit 101 in the opposite direction, the drive unit 101 translates to the side away from the lock member 102. Under the restoring force of the elastic reset member 103, the lock member 102 moves toward the direction close to the transmission roller 41, that is, the lock member 102 approaches the transfer unit 04, and the transfer unit 04 switches from the active state to the locked state.

[0190] In this embodiment, the lock 102 is in a 7-shaped shape, its slot 1021 or tooth end 517 is located in the longitudinal part of the lock 102, its inclined action surface 1022 is located in the transverse part of the lock 102, and part of the drive unit 101 extends from the top side wall of the cavity 3 or the water squeezing rack 1. At this time, the spatial layout of the elastic reset member 103, the slot 1021 or the tooth end 0418 is more reasonable, the setting position of the drive unit 101 is also convenient for operation, and the overall matching structure is more stable. Of course, the lock 102 can also only include the longitudinal part, which is not specifically limited.

[0191] The number of the transmission rollers 41 is one or two or more, and they are arranged in parallel along the pulling direction of the flat mop 9. In other words, two or more transmission rollers 41 are arranged up and down, and a plurality of transmission teeth 411 are evenly spaced around the outer wall of the transmission roller 41, so that the cleaning body can be evenly transmitted to the wiping object to avoid uneven distribution of the cleaning body. Of course, in other embodiments, the number of transmission rollers 41 is not limited, and it can be one or more.

[0192] When the number of the transfer rollers 41 is two or more, at least two transfer rollers 41 are arranged in a staggered manner, and the transfer roller 41 close to the squeezing member 2 is closer to the water squeezing channel 11 than the other transfer rollers 41. In other words, the transfer roller 41 close to the squeezing member 2 is arranged more towards the direction where the water squeezing channel 11 is located. Such an arrangement can increase the contact pressure between the wiper and the transfer roller 41, enabling the transfer roller 41 to rotate normally to transfer the cleaning body, and avoiding the situation where the transfer roller 41 close to the squeezing member 2 cannot rotate due to the ineffective contact after the wiper is squeezed and deformed.

[0193] The transfer roller 41 can be rotatably connected to the cavity 3 and face the water squeezing channel 11, or can be rotatably connected to the water squeezing frame 1 and face the water squeezing channel 11. The installation position of the transfer roller 41 can be not limited, as long as it can rotate to realize the transfer of the cleaning body.

[0194] During the use process, in the initial state, the transfer unit 04 is in a locked state, that is, the transfer roller 41 does not rotate. At this time, when the flat mop 9 is pulled up and down in the water squeezing channel 11 and pushed up and down relative to the squeezing member 2, the cleaning body will not be transferred to the wiper of the flat mop 9; when it is necessary to clean the wiper of the flat mop 9 with the cleaning body, an external force is applied to the driving part 101, so that the driving part 101 pushes the locking member 102 away from the transfer roller 41, and the transfer unit 04 switches from the locked state to the active state, that is, the transfer roller 41 can rotate. At this time, when the flat mop 9 is pulled up and down and pushed in the water squeezing channel 11, the wiper not only squeezes with 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 wiper, so as to transfer the cleaning body in the cavity 3 to the wiper, so that the wiper is washed by the cleaning body while squeezing with 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 driving part 101 is stopped, and under the restoring force of the elastic restoring member 103, the locking member 102 automatically moves towards the direction close to the transfer roller 41.

[0195] Other structures are the same as those in the first embodiment and will not be described again.

[0196] Embodiment Twelve

[0197] The difference between this embodiment and Embodiment XI is that the transfer part of the transfer unit 04 is a transmission sphere, which is rotatably arranged in a round hole opened on the side wall of the cavity 3. The number of round holes is multiple, and correspondingly, the number of transmission spheres is also multiple. They are spaced apart on the same plane of the cavity 3, so that all parts of the wiping object can receive the cleaning body conveyed by the transmission spheres. Of course, the multiple transmission spheres may not be located on the same plane, and there is no specific limitation. The outer wall of the transmission sphere is distributed with grooves, which are the concave-convex structures for obtaining the cleaning body. When the transmission sphere rolls, the cleaning body in the cavity 3 can be conveyed to the wiping object.

[0198] The locking unit 10 realizes the switching between the active state and the locked state of the transfer unit 04. Specifically, the locking unit 10 may include locking rods corresponding to the transmission spheres one by one. All the locking rods are connected to the same panel. By applying an external force to move the panel with the locking rods towards the direction where the transmission spheres are located, the locking rods are brought into contact with the transmission spheres, which can prevent the transmission spheres from rotating in the round holes. By applying a reverse external force to move the panel away from the transmission spheres, the locking rods and the transmission spheres can be separated, and the transmission spheres can rotate freely in the round holes. Of course, the above external force can also be realized by an elastic resetting member.

[0199] Other structures are the same as those in Embodiment XI and will not be described in detail.

[0200] Embodiment XIII

[0201] On the basis of Embodiment X, the transfer unit 04 can adopt the structure of the transmission roller and the scraping member in Embodiment V, and the cooperation between the locking member 72 and the engaging tooth portion 73 realizes the switching between the active state and the locked state of the transfer unit 04. Specifically, the locking member 72 moves relatively, so that it switches between two states of cooperating with the engaging tooth portion 73 and cooperating with the avoiding portion 74.

[0202] When an external force is applied to the dial 71 to make the locking member 72 engage with the engaging tooth portion 73, the transmission roller 41 stops rotating under the action of the locking member 72. At this time, the transmission roller 41 cannot drive the locking member 72 to move up and down, that is, there will be no mutual friction and scraping action between the locking member 72 and the cleaning body, and the transfer unit 04 enters the locked state. The avoiding portion 74 is a groove structure. When an external force is applied in the reverse direction to the dial 71 to disengage the locking member 72 from the engaging tooth portion 73 and the locking member 72 enters the relative position corresponding to the avoiding portion 74, the engaging teeth on the locking member 72 are in the avoiding portion 74 and do not act on the transmission roller 41. The transmission roller 41 can rotate freely, so that the scraping member 47 can move up and down under the drive of the transmission roller 41 to scrape the cleaning body, and the transfer unit 04 enters the active state.

[0203] Embodiment XIV

[0204] The transfer part is a mesh body, at least part of which is wrapped around the outer periphery of the cleaning body.

[0205] As Figures 46 - 48 shown, in this embodiment, the transfer part is an elastic foaming net, which is made of an elastic material and is connected to the opening of the cavity 3 on the side facing the water squeezing channel 11. The cleaning body is a solid cleaning soap, which is placed in the cavity 3, and its outer surface contacts the elastic foaming net. At this time, the elastic foaming net can be used as the concave-convex structure for scraping the cleaning body, and it is easy to adhere to the cleaning body and generate foam under the up-and-down pulling and pushing of the wiping object of the flat mop 9.

[0206] Compared with the transmission roller 41, the transmission sphere 43, the transmission roller 41 and the scraping part 47 in the above embodiment, the elastic foaming net does not move relative to the water squeezing frame 1.

[0207] In this embodiment, part of the elastic foaming net wraps the cleaning body, and the cavity 3 wraps part of the cleaning body. In other words, the elastic foaming net and the cavity 3 jointly wrap the cleaning body. Of course, in other embodiments, it can also be that the elastic foaming net wraps the cleaning body as a whole, and the two are placed in the cavity 3, or the elastic foaming net after wrapping the cleaning body as a whole is connected in the cavity 3.

[0208] Of course, the transfer part can also be an ordinary foaming net in existing products. After wrapping the cleaning body as a whole, the two are placed in the cavity 3 together, or the foaming net after wrapping the cleaning body as a whole is connected in the cavity 3. Or, the foaming net is connected to the opening of the cavity 3 facing the water squeezing channel 11 and wraps part of the cleaning body.

[0209] Of course, the above blocking unit can also be arranged between the mesh body and the wiping object in this embodiment.
