Detailed implementation manners

[0081] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below 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 the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0082] Embodiment 1

[0083] As Figures 1 - 9 shown, an extrusion mechanism for a flat mop includes a water squeezing frame 1, a squeezing member 2, a cavity 3, and a transmission unit 4.

[0084] The water squeezing frame 1 is formed with 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, and there is no specific limitation. The flat mop 9 can be pulled, pushed, and squeezed up and down inside the water squeezing channel 11. Or rather, the relative movement between the flat mop 9 and the water squeezing channel 11 realizes the up and down pulling, pushing, and squeezing of the flat mop 9.

[0085] The setting position of the squeezing member 2 is not limited for the time being. It is used to squeeze the wiping object of the flat mop 9 and realizes the up and down pulling, pushing, and squeezing cleaning of the flat mop 9.

[0086] 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, etc. The cavity 3 being arranged on the water squeezing rack 1 can be that the cavity 3 is set as an independent component within 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 one body. 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. 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.

[0087] At least part of the transmission unit 4 can interact with the flat mop 9. The interaction between the above-mentioned transmission unit 4 and the flat mop 9 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 part of the transmission unit 4 to move, or when the flat mop 9 is pulled, pushed, and squeezed 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 object of the flat mop 9. It at least has a movable part 40 that can rotate relative to the flat mop 9, and the movable part 40 has a concave-convex structure for obtaining the cleaning body. As Figure 7 shown, in this embodiment, the movable part 40 is a 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 object through the contact between the wiping object 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 object. Of course, the situation where the transfer part of the transmission unit 4 has no concave-convex structure is not excluded. The transfer part being a smooth plane 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.

[0088] The transmission unit 4 at least has 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 object of the flat mop 9, so as to transfer the cleaning body in the cavity 3 to the wiping object, enabling the flat mop 9 to perform in-depth cleaning of the cleaning body while being pulled, pushed, 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 object. At this time, the flat mop 9 is pulled, pushed, and squeezed for cleaning in the water squeezing channel 11 to complete the rinsing of the wiping object, avoiding a large amount of the cleaning body remaining on the wiping object when the flat mop 9 is mopping the floor.

[0089] 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 the situation where the transmission unit 4 does not contact the wiping object of the flat mop 9 is not excluded, but the situation where 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.

[0090] For the switching between the working state and the waiting state of the transmission unit 4, it can be achieved by changing the relative positions of at least part of the transmission unit 4 and the wringing rack 1. Or rather, it is achieved 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.

[0091] 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 no specific limitation is made (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.

[0092] 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 no specific limitation is made. 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 frame 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.

[0093] 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 enters the water squeezing channel 11 and is pulled, 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 enters the water squeezing channel 11 and is pulled, the squeezing member 2 plays a role, and at the same time the transmission unit 4 transmits the cleaning body to the wiping object.

[0094] 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.

[0095] 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.

[0096] For the convenience of assembly and relatively stable structure after assembly, the water squeezing frame 1 is divided into upper and lower layer frames. The squeezing member 2 is fixedly connected to the upper layer frame of the water squeezing frame 1, the cavity 3 is movably connected to the lower layer frame, and both the cavity 3 and the squeezing member 2 extend in the entire width direction of the water squeezing frame 1.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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, the positioning assembly 7 cooperates with the driving assembly 6 in a limited position. Specifically, the positioning assembly 7 is a convex rib structure provided on the water squeezing frame 1. The convex rib can abut against the toggle member 61 of the driving assembly 6, so that the toggle member 61 stays in this position. Only by applying a greater external force can the toggle member 61 pass over the convex rib and switch to another state. There is at least one convex rib, which can cooperate with two grooves, so that the toggle member 61 can stay when the transmission unit 4 is in a working state or in a waiting state. Of course, in other embodiments, it can also be other limiting structures in the prior art, which are not specifically limited.

[0102] 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 toggle member connected to the cavity 3. When an external force is applied to drive the toggle member to translate in the longitudinal groove, the cavity 3 is driven to move synchronously closer to or away from the water squeezing channel 11, thereby achieving the purpose of moving the transmission unit 4 closer to or away from the water squeezing channel 11, and the transmission unit 4 switches between the working state and the waiting state.

[0103] When the cleaning body in the cavity 3 is a solid cleaning soap, the volume of the fixed cleaning soap becomes smaller after long-term use. In order to ensure that it can always effectively contact the transmission unit 4, the squeezing mechanism may further include a holding unit 8, which presses the solid cleaning soap toward the side where the transmission unit 4 is located. Specifically, the holding 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 is deformed, the compressed elastic member 82 continues to extend, and the cleaning body is pushed toward the transmission unit 4 by the pressing plate 81.

[0104] A hands-free flat mop comprises a flat mop 9 with a wiping object, a mop rod 91 rotatably connected to the flat mop 9, and a squeezing mechanism of the above structure.

[0105] 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.

[0106] Embodiment 2

[0107] like Figures 12 - 14 As shown, the difference between this embodiment and the first embodiment is that the movable part 40 of the transmission unit 4 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 transmitted to the wiping object.

[0108] The other structures are the same as those in the first embodiment and will not be described in detail.

[0109] Embodiment 3

[0110] 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 .

[0111] 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 .

[0112] Specifically, the water squeezing frame 1 and the cavity 3 are relatively independent. The driving wheel 63 is rotatably connected to the water squeezing frame 1, and a part of the driving wheel 63 protrudes from the surface of the water squeezing frame 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.

[0113] 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.

[0114] Embodiment 4

[0115] In this embodiment, at least part of the driving assembly 6 rotates, thereby driving the cavity 3 to translate relative to the water squeezing frame 1.

[0116] As Figures 21 - 26 shown, the driving assembly 6 includes a rotating wheel 64, a driving column 641 eccentrically arranged on the rotating wheel 64, and a transverse groove 32 arranged in the cavity 3. Specifically, the water squeezing frame 1 and the cavity 3 are relatively independent. The rotating wheel 64 is rotatably connected to the water squeezing frame 1, and the driving column 641 is stuck in the transverse groove 32, that is, the outer diameter of the driving column 641 is approximately equal to the width of the transverse groove 32.

[0117] Apply an external force to rotate the rotating wheel 64. The driving column 641 can move in 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 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.

[0118] 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 in the figure, a limiting groove 13 is provided on the water squeezing rack 1. When the limiting convex rib 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 also be provided on the cavity 3. When the limiting convex rib 642 falls into the limiting groove 13 of the cavity 3, the transmission unit 4 is limited to the waiting state.

[0119] Embodiment Five

[0120] The difference between this embodiment and Embodiment One lies in the different structure of the transmission unit 4.

[0121] As Figures 27 - 30 shown, the transmission unit 4 includes a third part 46 and a fourth part 47. Both the above-mentioned third part 46 and fourth part 47 face the water squeezing channel 11. Relatively speaking, the third part 46 is located above the fourth part 47. When the flat mop 9 is pulled up and down and pushed, it can drive the third part 46 to rotate. While the third part 46 rotates, it drives the fourth part 47 to move, so that the fourth part 47 moves to scrape the cleaning body.

[0122] As Figure 29 shown, in this embodiment, the third part 46 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 part 461 is also connected to the driving roller, that is, the center line of the crank part 461 does not overlap with the center line of the rotating shaft 462.

[0123] As Figure 30 shown, the fourth part 47 is a scraping part for scraping the cleaning body. The scraping part is connected with a movable groove 471 for the crank part 461 to extend into. The width of the movable groove 471 is roughly equivalent to the outer diameter of the crank part 461, and the length of the movable groove 471 is greater than the outer diameter of the crank part 461. When the driving roller rotates relative to the water squeezing rack 1, the crank part 461 moves up and down in the movable groove 471, thereby driving the scraping part 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 part and transmitted to the wiping object.

[0124] When the third part 46 rotates relatively to drive the fourth part 47 to move up and down, the transmission unit 4 enters the working state. When the third part 46 stops rotating relatively, it cannot drive the fourth part 47 to move up and down. At this time, the transmission unit 4 enters the waiting state.

[0125] In this embodiment, the positioning component 7 for limiting the transmission unit 4 to the working state or the waiting state specifically includes a knob 71 partially protruding from the surface of the extrusion mechanism, a locking member 72 connected to the knob 71, and an engaging tooth portion 73 and an avoidance 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 engaging tooth portion 73 and cooperating with the avoidance portion 74.

[0126] When an external force is applied to the knob 71 so that the locking member 72 meshes with the engaging 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 scraping member to move up and down, that is, there will be no mutual friction scraping action between the scraping member and the cleaning body, and the transmission unit 4 enters the waiting state. The avoidance portion 74 is a groove structure. When an external force is applied in the reverse direction to the knob 71 so that the locking member 72 disengages from the engaging tooth portion 73 and the locking member 72 enters the relative position corresponding to the avoidance portion 74, the engaging teeth on the locking member 72 are within the avoidance portion 74 and it will not act on the driving roller, and the driving roller can rotate freely. Thus, the scraping member can move up and down (here, up and down is illustrated by the Figure 28 indicated direction) under the drive of the driving roller to scrape the cleaning body, and the transmission 4 enters the working state.

[0127] Another function of the engaging tooth portion 73 is to better transmit the acting force of the wiping material to the driving roller, so that the driving roller can rotate around its own rotating shaft 462. In this structure, both the driving roller and the scraping member can be understood as the movable part 40 of the transmission unit 4. The scraping member can be understood as the concave-convex structure on the movable part 40. Specifically, in this embodiment, the scraping member can be a grid-like structure, and the cleaning body is transmitted from the gap to the wiping material.

[0128] 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, and it can generally be understood as the partial structure corresponding to storing the cleaning body.

[0129] Embodiment Six

[0130] The difference between this embodiment and Embodiment One lies in the different structure of the transmission unit 4.

[0131] As Figures 31 - 34 shown, the transmission unit 4 includes a first part 44 and a second part 45. The first part 44 faces 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 in and out under the action of the second part 45.

[0132] 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 will not be elaborated here. 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 demarcation line between it and the water squeezing frame 1.

[0133] The second part 45 includes a first lifting member 451 and a second lifting member 452 that are rotatably connected to the cavity 3 or the water squeezing frame 1, a first movable member 453 connected to the first lifting member 451, a second movable member 454 connected to the second lifting member 452, and a force applying member 455. The first lifting member 451 and the second lifting member 452 extend in the entire width direction of the extrusion mechanism and are generally rod-shaped. The key is that both the first lifting member 451 and the second lifting member 452 are provided with lifting paddles 450, and the first lifting member 451 is also connected with an extension arm 459.

[0134] The number of the first movable members 453 is at least two, which are respectively located at both ends of the first lifting member 451 and are connected to the first lifting member 451 at an angle. Similarly, the number of the second movable members 454 is also at least two, which are respectively located at both ends of the second lifting member 452 and are connected to the second lifting member 452 at an angle. A vertical sliding column 456 is provided on the first movable member 453, and a track groove 457 is provided on the second movable member 454. After assembly, the sliding column 456 falls into the track groove 457.

[0135] 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 mechanism, the arc-shaped sliding rail 458 drives the extension arm 459 to move, causing the first lifting member 451 to rotate and driving the lifting paddle 450 to rotate. At this time, the sliding column 456 moves in the track groove 457, and the lifting paddle 450 on the second lifting member 452 also rotates. Therefore, the lifting paddles 450 on the first lifting member 451 and the second lifting member 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 paddles 450 on the first lifting member 451 and the second lifting member 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.

[0136] The positioning component 7 in this embodiment can be a card slot structure provided at both ends of the arc-shaped sliding rail 458. That is, the positioning component 7 is in limit cooperation with the transmission unit 4, and specific limitations are not made.

[0137] Embodiment Seven

[0138] As Figure 35 、 Figure 36As shown in the figure, in this embodiment, the transmission unit 4 and the extrusion member 2 are both disposed 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.

[0139] By applying an external force on the knob 13, the cavity 3 can be rotated relative to the water squeezing frame 1. When the extrusion member 2 rotates to the side facing 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 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 the unused 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.

[0140] The specific structure of the transmission unit 4 is similar to that of the first embodiment and will not be elaborated here.

[0141] Embodiment Eight

[0142] As Figures 37 - 39 shown in the figure, 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 exert a squeezing effect on 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 transmission unit 4, thereby isolating the transmission unit 4 from the wiping material. Of course, the blocking unit 5 may not pass through the extrusion member 2, but may pass out between the extrusion member 2 and the transmission unit 4. Or, the blocking unit 5 moves to between the wiping material and the transmission unit 4. Or, the blocking unit 5 moves to between the cleaning body and the transmission unit 4. There is no specific limitation, and its ultimate purpose is to isolate the transmission unit 4 from the wiping material.

[0143] 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 transmission unit 4 is isolated from the wiping object. 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 transmission unit 4. 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.

[0144] Of course, the above squeezing member 2 can also be movably connected to the water squeezing frame 1, and there is no specific limitation.

[0145] 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.

[0146] Embodiment Nine

[0147] 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. The transmission unit 4 is arranged on one 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 realized respectively.

[0148] When the squeezing member 2 needs to squeeze with 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 with the wiping object in the water squeezing channel 11; when the transmission unit 4 needs 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.

[0149] 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.

[0150] Embodiment Ten

[0151] In this embodiment, at least part of the driving component 6 undergoes translation and rotation, thereby driving the cavity 3 to move relative to the water squeezing frame 1, so that the cavity 3 approaches or moves away from the water squeezing channel 11.

[0152] 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, and the straight tooth section of this movable part also meshes with the dial. At the same time, this 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.

[0153] The other structures are the same as those in the first embodiment and will not be described in detail.

[0154] Embodiment XI

[0155] A hands-free flat mop includes a flat mop 9 with a wiping object, a mop rod 91 rotatably connected to the flat mop 9, and a squeezing mechanism with any of the structures in the first to tenth embodiments above.
