Description

Technical Field

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

Moreover, the up-and-down pulling and pushing process of the flat mop not only automatically acquires the cleaning material but also works in conjunction with the squeezing component. 4) The transfer unit has a working state and a waiting state. The drive component controls the transfer unit to switch between the two states. The two steps of squeegee cleaning and cleaning with the cleaning agent can be performed simultaneously or separately, which is highly flexible and avoids the situation where too much cleaning agent remains on the wiping material; 5) The transfer unit has multiple switching methods between the working state and the waiting state, which is suitable for different usage scenarios; 6) The transfer unit includes a rotatable transfer roller with evenly distributed transfer teeth on the outer circumference of the transfer roller to ensure that the cleaning agent is evenly distributed to the wiping material and avoids the situation where too much cleaning agent is in one place, resulting in no cleaning. 7) The drive assembly facilitates the horizontal movement of the cavity relative to the wringer, making operation simpler; 8) The positioning assembly ensures the transmission unit remains stably in working or waiting states, preventing accidental deviation during use. This effectively isolates deep cleaning and rinsing of the flat mop, and prevents the cleaning agent from being transferred outwards during waiting, thus avoiding excessive loss of cleaning agent; 9) The holding unit ensures that the transmission unit remains in contact with the cleaning agent and effectively transfers it to the wiping surface even after prolonged use; 10) The cleaning agent provides excellent stain removal for the flat mop and can remove... Odor, and the cleaning body can increase the lubrication of the surface of the flat mop during washing, extending the service life of the wiping object; 11) The cleaning body, the transmission unit, and the flat mop wiping object work together. In the working state, the flat mop wiping object moves in the wringing channel, which can drive the transmission unit to move to obtain the cleaning body. In the waiting state, the flat mop wiping object cannot drive the transmission unit to move in the wringing channel, or even if it does drive the transmission unit to move, it cannot contact the cleaning body, and thus cannot obtain the cleaning body. The overall structure is simple, combining deep cleaning and rinsing, realizing the automatic acquisition of the cleaning body and friction foaming, with high cleaning efficiency.

Detailed Implementation

[0078] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0079] Example 1

[0080] like Figures 1-9 As shown, a flat mop squeezing device includes a wringer 1, a squeezing component 2, a cavity 3, and a transmission unit 4.

[0081] The wringer 1 has a wringing channel 11 for inserting the flat mop 9. Alternatively, the wringer 1 and the cavity 3 can be combined to form the wringing channel 11. No specific limitation is made. The flat mop 9 can be pulled up and down and pushed inside the wringing channel 11. In other words, the flat mop 9 and the wringing channel 11 move relative to each other to achieve the up and down pulling and pushing of the flat mop 9.

[0082] The location of the extrusion component 2 is not limited at the moment. It is used to extrude the wiping material of the flat mop 9 and to clean the flat mop 9 by pulling and pushing it up and down.

[0083] The cavity 3 is located on the wringer 1 and is used to store the cleaning agent. The cleaning agent is not limited; it can be a liquid detergent or a solid cleaning soap, such as regular soap. The cavity 3 can be a separate component within the wringer 1, or it can be integrated with the wringer 1. This structure also corresponds to the formation of the wringing channel 11. When the wringer 1 and the cavity 3 are relatively independent, the wringing channel 11 is formed by the wringer 1. When the wringer 1 and the cavity 3 are connected, the wringing channel 11 is formed by the wringer 1. Of course, the cavity 3 does not have to be a relatively independent component; it can be broadly understood as part of the structure corresponding to the storage of the cleaning agent.

[0084] At least a portion of the transmission unit 4 can interact with the flat mop 9. This interaction can occur when the flat mop 9 moves up and down within the wringing channel 11, driving at least a portion of the transmission unit 4 to move; or it can occur when the flat mop 9 moves up and down within the wringing channel 11, with both working together. The specific interaction is not limited, thereby transferring the cleaning material within the cavity 3 to the wiping material on the flat mop 9. The transmission unit 4 has at least a movable part 40 that can rotate relative to the flat mop 9, and this movable part 40 has a concave-convex structure for acquiring the cleaning material. For example... Figure 7 As shown, in this embodiment, the movable part 40 is a transfer roller 41, whose outer wall is evenly distributed with transfer teeth 411. These transfer teeth 411 are the uneven structure used to acquire the cleaning body. The transfer roller 41 can rotate around the rotating shaft 42, thereby transferring the cleaning body in the cavity 3 first into the space between adjacent transfer teeth 411, and then transferring the cleaning body 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 transported to the wiping object. Of course, it is not excluded that the transfer part of the transfer unit 4 does not have an uneven structure; the transfer part can also achieve the transfer of the cleaning body by being a smooth plane. In addition, the uneven structure here also includes structures with small unevenness, such as rough surfaces.

[0085] The transmission unit 4 has at least a working state for transmitting cleaning agents to the wiping material of the flat mop 9 and a waiting state for stopping the transmission of cleaning agents to the wiping material of the flat mop 9. In the working state, the cleaning agent abuts against the transmission unit 4, and at least a portion of the transmission unit 4 contacts or tends to contact the wiping material of the flat mop 9. Specifically, the wiping material of the flat mop 9 contacts at least a portion of the transmission unit 4. Thus, during the process of the flat mop 9 being pulled up and down relative to the wringing channel 11, it drives the transmission unit 4 to move, so that the transmission unit 4 can acquire the cleaning agent in the cavity 3 and transmit it to the wiping material of the flat mop 9. This allows the cleaning agent in the cavity 3 to be transmitted to the wiping material, so that when the flat mop 9 is pulled up and down to wring water in the wringing channel 11, it can simultaneously perform deep cleaning of the cleaning agent, resulting in a better cleaning effect of the flat mop 9. Moreover, since the wiping material of the flat mop 9 is pulled up and down relative to the squeezing member 2 after the cleaning agent adheres to it, it can generate rich foam, which improves the cleaning effect. In the waiting state, the transmission unit 4 stops transmitting cleaning material to the wiping object. At this time, the flat mop 9 is pulled out and squeezed to clean the wiping object in the wringing channel 11, completing the rinsing of the wiping object and avoiding the flat mop 9 leaving too much cleaning material on the wiping object when mopping the floor. It should be noted that in the waiting state, the cleaning material can be offset by the transmission unit 4, or the two can not offset each other.

[0086] It should be noted that the statement that "at least a portion of the transmission unit 4 tends to contact the wiping material of the flat mop 9" means that it is possible for the transmission unit 4 not to come into contact with the wiping material of the flat mop 9, but the transmission unit 4 has already brought the cleaning body into contact with the wiping material. The statement that "at least a portion of the transmission unit 4" refers to situations where the entire transmission unit 4 is in contact with the wiping material, only a small portion of the transmission unit 4 is in contact with the wiping material, or the vast majority of the transmission unit 4 is in contact with the wiping material.

[0087] The switching between the working state and the waiting state of the transmission unit 4 can be achieved by changing the relative position of at least a portion of the transmission unit 4 and the wringer 1. Alternatively, it can be achieved by changing the relative position of at least a portion of the cavity 3 and at least a portion of the transmission unit 4. It should be noted that the at least a portion of the cavity 3 here includes the cleaning body within the cavity 3.

[0088] Specifically, the transmission unit 4 and the cavity 3 are movably connected to the dewatering frame 1. The transmission unit 4 and the cavity 3, as a whole, can move relative to the dewatering frame 1. This movement can be translational or non-linear, thereby enabling the transmission unit 4 to switch between a working state and a waiting state (the specific structure will be explained in Embodiments 1, 3, and 4). It should be noted that translation here does not refer to horizontal movement, but rather to linear movement. It can be translation in the horizontal direction, or translation in the vertical direction, or translation in the inclined direction, without any specific limitation (the translation mentioned below is interpreted in this way). In addition, the relative relationship between the transmission unit 4 and the cavity 3 is not limited. The transmission unit 4 can be located between the cavity 3 and the dewatering channel 11, that is, the cavity 3, the transmission unit 4, and the dewatering channel 11 are arranged side by side, or the transmission unit 4 and the cavity 3 can be arranged side by side on the same side of the dewatering channel 11. Alternatively, the transmission unit 4 can be rotatably connected to the wringer 1. This means that a portion of the transmission unit 4 can rotate around its own axis, and the transmission unit 4 can rotate relative to the wringer 1, such that the transmission unit 4 rotates to the side of the wringer 1 facing the wringer channel 11, or it can rotate to the side away from the wringer channel 11, thereby switching the transmission unit 4 between a working state and a waiting state (the specific structure will be described in Embodiment Seven). Alternatively, at least a portion of the cavity 3 can move relative to the wringer 1, thereby changing the relative position of at least a portion of the transmission unit 4 with the cleaning body, thereby switching the transmission unit 4 between a working state and a waiting state (the specific structure will be described in Embodiment Six). It should be noted that at least a portion of the cavity 3 here can be the cavity 3 itself, or it can include the cleaning body within the cavity 3. Alternatively, the transmission unit 4 can be movably connected to the wringer 1, and at least a portion of the transmission unit 4 can move relative to the wringer 1. This movement can be translational or non-linear, allowing the transmission unit 4 to approach the cleaning material within the cavity 3 and scrape the cleaning material to convey it to the wiping material, thereby achieving the switching between a working state and a waiting state for the transmission unit 4 (the specific structure will be described in Embodiment 5). Or, the transmission unit 4 can be movably connected to the wringer 1, and at least a portion of the transmission unit 4 can move relative to the wringer 1. This movement can be translational or non-linear, allowing the transmission unit 4 to approach or move away from the wringer channel 11, thereby achieving the switching between a working state and a waiting state for the transmission unit 4.

[0089] Specifically, regarding the structure of this embodiment, as follows: Figure 4 , Figure 7As shown, the extruder 2 is fixedly mounted on the side of the dewatering frame 1 facing the dewatering channel 11. Alternatively, the extruder 2 can be movably connected to the dewatering frame 1; there are no specific limitations. The cavity 3 is movably mounted on the dewatering frame 1, with one side open. The transmission unit 4 is connected to the open side of the cavity 3, specifically positioned on the side of the cavity 3 facing the dewatering channel 11. Under external force, the cavity 3 can move relative to the dewatering frame 1, thereby allowing the transmission unit 4 to switch between a working state and a waiting state. Figure 3 , Figure 4 Taking the direction shown as an example, the cavity 3 can move left and right relative to the wringer 1. When the cavity 3 moves to the right, the transmission unit 4 is closer to the wiping material of the flat mop 9, so that the transmission unit 4 enters the working state. When the cavity 3 moves to the left, the transmission unit 4 moves away from the wiping material of the flat mop 9, so that the transmission unit 4 enters the waiting state.

[0090] by Figure 3 , Figure 4 Taking the example shown, the transmission unit 4 is in a waiting state, located on the side of the squeezing member 2 away from the wringing channel 11, that is, the transmission unit 4 is located to the left of the squeezing member 2. When the flat mop 9 enters the wringing channel 11 and is pulled out, only the squeezing member 2 is active, and the transmission unit 4 does not transfer the cleaning material to the wiping object. When the transmission unit 4 enters the working state, it moves to the right, becoming flush with the squeezing member 2. When the flat mop 9 enters the wringing channel 11 and is pulled out, the squeezing member 2 is active, and the transmission unit 4 transfers the cleaning material to the wiping object.

[0091] More specifically, such as Figures 7-9 As shown, in this embodiment, the transmission unit 4 includes two transmission rollers 41 rotatably connected to the cavity 3, arranged parallel to the pulling direction of the flat mop 9. In other words, the two transmission rollers 41 are arranged vertically, and multiple transmission teeth 411 are evenly distributed around the outer wall of the transmission rollers 41, thereby uniformly transmitting the cleaning material to the wiping object and avoiding uneven distribution of the cleaning material. Of course, in other embodiments, the number of transmission rollers 41 is not limited; it can be one or more.

[0092] To facilitate assembly, the sidewall of the cavity 3 is formed with an elastic mounting sidewall structure, and a rotating shaft 42 is formed on the inner side of the elastic mounting sidewall. The transmission roller 41 is inserted between the two rotating shafts 42, and the transmission roller 41 can rotate around the rotating shaft 42. Thus, the cleaning body located in the cavity 3 can be transmitted to the wiping object under the rotation of the transmission roller 41. More specifically, the inner side of the transmission roller 41 contacts the cleaning body in the cavity 3, and after rotating, it drives it outward, continuously rotating in the same direction to realize the continuous transmission of the cleaning body.

[0093] For ease of assembly and relatively stable structure after assembly, the dewatering frame 1 is divided into upper and lower frames. The extrusion component 2 is fixedly connected to the upper frame of the dewatering frame 1, and the cavity 3 is movably connected to the lower frame. Both the cavity 3 and the extrusion component 2 extend across the entire width of the dewatering frame 1.

[0094] In this embodiment, the driving component 6 drives the cavity 3 to translate. At least a portion of the driving component 6 is movably disposed on the wringer 1. The movement includes translation, rotation, and pressing. That is, the driving component 6 translates, rotates, or presses to drive the cavity 3 to translate relative to the wringer 1. Specifically, in this embodiment, the driving component 6 includes at least a shifting groove 12 formed on the wringer 1, a shifting member 61 movably connected to the wringer 1, and a movable track 62 formed on the cavity 3. The shifting groove 12 extends along the width direction of the wringer 1. A portion of the shifting member 61 extends into the movable track 62, and a portion of the shifting member 61 is located within the shifting groove 12. When an external force is applied to drive the shifting member 61 to move within the shifting groove 12 relative to the wringer 1, the cavity 3 can extend or retract from the wringer 1.

[0095] like Figure 10 , Figure 11 As shown, part of the actuating member 61 extends from the top of the wringer 1 and through the actuating transverse groove 12, and part of the actuating member 61 passes through the extruder 2 and engages 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 extruder 2, and two actuating parts 611 that can extend into the movable tracks 62 are provided on the actuating member 61.

[0096] like Figure 9 As shown, the movable track 62 includes a first slide 621, a second slide 622 parallel to the first slide 621, and a transition slide 623 connecting the first slide 621 and the second slide 622. The transition slide 623 is inclined. Of course, the first slide 621 and the second slide 622 do not necessarily have to be completely parallel; they only need to be not on the same straight line. Specifically, the first slide 621 extends along the width direction of the cavity 3. The entire movable track 62 is a Z-shaped slide. Here, a Z-shaped slide refers to a shape that is close to a Z shape. It does not necessarily have to be a standard Z shape; it can also be a mirror image of a Z. The first slide, the second slide, and the transition slide do not necessarily have to be straight tracks; they can also be curved tracks, as long as the first slide 621 and the second slide 622 have a height difference and are connected to each other. The specific shape is not limited.

[0097] When an external force is applied to cause the actuating member 61 to move relative to the squeezing frame 1 within the actuating transverse groove 12, the two actuating parts 611 of the actuating member 61 can only move laterally due to the restriction of the actuating transverse groove 12. Once it moves beyond the lateral width of the first slide groove 621 or the second slide groove 622, it will inevitably enter the transition slide groove 623. Since the actuating part 611 can only move laterally, the actuating part 611 moves against the transition slide groove 623, and the cavity 3 moves inward and outward under the drive of the actuating part 611.

[0098] In the above structure, the drive component 6 is linked with the cavity 3 to control the cavity 3 to move away from or closer to the transmission unit 4, thereby realizing the switching of the transmission unit 4 between the working state and the waiting state, that is, realizing the control of the drive component 6 to switch the transmission unit 4 between the working state and the waiting state.

[0099] Since the transmission unit 4 and the cavity 3 are connected together, the drive component 6 controls the transmission unit 4 and the cavity 3 to move away from or closer to the transmission unit 4 synchronously, thereby realizing the switching of the transmission unit 4 between the working state and the waiting state. That is, the drive component 6 controls the transmission unit 4 to switch between the working state and the waiting state.

[0100] Of course, the transmission unit 4 and the cavity 3 can also be set relatively independently. In this case, even if the drive component 6 only controls the cavity 3 to move away from or closer to the transmission unit 4, the relative position of the transmission unit 4 remains unchanged. Alternatively, the drive component 6 only controls the transmission unit 4 to move away from or closer to the squeezing channel 11, and the relative position of the cavity 3 remains unchanged. Since the transmission unit 4 cannot obtain the cleaned body in the cavity 3, the transmission unit 4 can switch between the working state and the waiting state.

[0101] To ensure that the transmission unit 4 can stably remain in the working or waiting state, a positioning component 7 is also included to limit the transmission unit 4 in the working or waiting state. In this embodiment, as shown... Figure 5 , Figure 6 As shown, the positioning component 7 and the driving component 6 are mutually limiting. Specifically, the positioning component 7 is a rib structure provided on the wringer 1. This rib can abut against the actuating member 61 of the driving component 6, thereby stopping the actuating member 61 in that position. Only by applying a greater external force can the actuating member 61 be moved past the rib to switch to another state. There is at least one rib, which can cooperate with two grooves, allowing the actuating member 61 to remain in the working state or the waiting state of the transmission unit 4. Of course, in other embodiments, other limiting structures in the prior art can also be used, and there is no specific limitation.

[0102] Of course, the structure can be simplified. The drive component 6 can also include a longitudinal groove structure opened on the squeezing frame 1 and a toggle member connected to the cavity 3. When an external force is applied to drive the toggle member to move in the longitudinal groove, the cavity 3 is driven to move synchronously closer to or away from the squeezing channel 11, so as to achieve the purpose of the transmission unit 4 moving closer to or away from the squeezing channel 11, and the transmission unit 4 switching between the working state and the waiting state.

[0103] When the cleaning agent in the cavity 3 is a solid cleaning soap, its volume decreases after prolonged use. To ensure effective contact between the soap and the transmission unit 4, the extrusion device may include a holding unit 8. This holding unit 8 presses the solid cleaning soap against the side where the transmission unit 4 is located, thus maintaining contact between the cleaning agent and the transmission unit 4. Specifically, the holding unit 9 includes at least a pressure plate 81 that contacts the cleaning agent and an elastic member that abuts against the pressure plate 81. The other end of the elastic member abuts against the side wall of the cavity 3. As the volume of the cleaning agent in the cavity 3 deforms, the compressed elastic member 82 continuously elongates, pushing the cleaning agent towards the transmission unit 4 using the pressure plate 81.

[0104] A hands-free flat mop includes a flat mop 9 with a wiping agent, a mop handle 91 rotatably connected to the flat mop 9, and a squeezing device with the above structure.

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

[0106] Example 2

[0107] like Figures 12-14As shown, the difference between this embodiment and Embodiment 1 is that the movable part 40 of the transmission unit 4 is a transmission ball 43, which is rolled within a circular hole 431, which is formed on the side wall of the cavity 3. There are multiple circular holes 431, and correspondingly, multiple transmission balls 43, which are spaced apart on the same plane of the cavity 3, so that all parts of the wiping object can receive the cleaning material transported by the transmission balls 43. Of course, the multiple transmission balls 43 may not be located on the same plane; there is no specific limitation. The outer wall of the transmission ball 43 has grooves 432, which are the concave-convex structures for acquiring the cleaning material. When the transmission ball 43 rolls, it can transport the cleaning material in the cavity 3 to the wiping object.

[0108] The other structures are the same as in Embodiment 1, and will not be described again.

[0109] Example 3

[0110] The difference between this embodiment and Embodiment 1 is that at least a portion of the drive component 6 rotates, thereby causing the cavity 3 to translate relative to the squeezing frame 1.

[0111] like Figures 15-20 As shown, the drive assembly 6 includes a drive wheel 63, an external threaded section 631 extending vertically from the center of the drive wheel 63, and an internal threaded portion 31 disposed in the cavity 3.

[0112] Specifically, the wringer 1 and the cavity 3 are relatively independent. The drive wheel 63 is rotatably connected to the wringer 1, and part of the drive wheel 63 extends out of the surface of the wringer 1. A flat plate is connected to the outer wall of the cavity 3. The flat plate forms a notch for supporting the external threaded section 631, and the inner wall of the notch forms an internal threaded section 31.

[0113] When an external force is applied to rotate the drive wheel 63, the external thread section 631 and the internal thread section 31 engage, which can drive the cavity 3 to move. For example, when the drive wheel 63 rotates in the forward direction, the cavity 3 moves away from the squeezing channel 11, so that the wiping material can only contact the extruder 2, but cannot contact the cleaning body of the transmission unit 4, or in other words, cannot contact the transmission ball 43, so that the transmission ball 43 cannot rotate to continuously transport the cleaning body in the cavity 3 to the wiping material. At this time, the transmission unit 4 enters the waiting state. When the drive wheel 63 rotates in the reverse direction, the cavity 3 moves closer to the squeezing channel 11, and the transmission unit 4 enters the working state.

[0114] Example 4

[0115] In this embodiment, at least a portion of the drive component 6 rotates, thereby causing the cavity 3 to translate relative to the dewatering frame 1.

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

[0117] When an external force is applied to rotate the rotating wheel 64, the drive column 641 can move within the transverse groove 32, thereby driving the cavity 3 to move. For example, when the rotating wheel 64 rotates clockwise, the cavity 3 moves away from the squeezing channel 11, so that the wiping material can only contact the squeezing element 2, but cannot contact the cleaning body of the transmission unit 4, or in other words, cannot contact the transmission ball 43, so that the transmission ball 43 cannot rotate to continuously transport the cleaning body in the cavity 3 to the wiping material. At this time, the transmission unit 4 enters the waiting state. When the rotating wheel 64 rotates counterclockwise, the cavity 3 moves closer to the squeezing channel 11, and the transmission unit 4 enters the working state.

[0118] To limit the transmission unit 4 to either the working state or the waiting state, such as Figure 26 As shown, a limiting protrusion 642 is provided on the rotating wheel 64, such as... Figure 23 As shown, a limiting groove 13 is provided on the dewatering frame 1. When the limiting protrusion 642 falls into the limiting groove 13, the transmission unit 4 is limited to the working state. Similarly, another limiting groove (not shown in the figure) can be provided on the cavity 3. When the limiting protrusion 642 falls into the limiting groove 13 of the cavity 3, the transmission unit 4 is limited to the waiting state.

[0119] Example 5

[0120] The difference between this embodiment and Embodiment 1 is that the structure of the transmission unit 4 is different.

[0121] like Figures 27-30 As shown, the transmission unit 4 includes a third part 46 and a fourth part 47, both of which are positioned towards the wringing channel 11, with the third part 46 located above the fourth part 47. When the flat mop 9 is pulled up and down, it drives the third part 46 to rotate. Simultaneously, the rotation of the third part 46 causes the fourth part 47 to move, thereby enabling the fourth part 47 to scrape the cleaning material.

[0122] like Figure 29 As shown, in this embodiment, the third part 46 is a drive roller, which is rotatably connected to the wringer 1 and can contact the wiping material of the flat mop 9. Under the drive of the wiping material, it rotates relative to itself around its own axis 462. The drive roller is also eccentrically connected to a crank part 461, that is, the center line of the crank part 461 does not overlap with the center line of the axis 462.

[0123] like Figure 30 As shown, the fourth part 47 is a scraper for scraping the cleaning agent. This scraper is connected to a movable groove 471 into which the crank portion 461 extends. The width of the movable groove 471 is approximately equal to the outer diameter of the crank portion 461, and the length of the movable groove 471 is greater than the outer diameter of the crank portion 461. When the drive roller rotates relative to the wringer 1, the crank portion 461 moves up and down within the movable groove 471, thereby driving the scraper to move up and down. In this embodiment, the cleaning agent is solid cleaning soap. During the upward or downward movement of the scraper, the solid cleaning soap can be scraped and transferred to the wiping material.

[0124] When the third part 46 rotates relative to the fourth part 47, the transmission unit 4 enters the working state. When the third part 46 stops rotating relative to the fourth part 47, it can no longer move the fourth part 47 up and down, and the transmission unit 4 enters the waiting state.

[0125] In the above structure, the drive component 6 is linked with the transmission unit 4 to control the transmission unit 4 to move or stop moving, thereby realizing the switching of the transmission unit 4 between the working state and the waiting state, that is, realizing the drive component 6 to control the transmission unit 4 to switch between the working state and the waiting state.

[0126] In this embodiment, the positioning component 7 for limiting the transmission unit 4 to a working state or a waiting state specifically includes a knob 71 that partially protrudes from the surface of the extrusion device, a locking member 72 connected to the knob 71, and a meshing tooth portion 73 and a clearance portion 74 located on the outer wall of the drive roller. The locking member 72 can move relative to the meshing tooth portion 73, allowing it to switch between two states: engaging with the meshing tooth portion 73 and engaging with the clearance portion 74.

[0127] When an external force is applied to the dial 71, causing the locking member 72 to engage with the meshing teeth 73, the drive roller stops rotating under the action of the locking member 72. At this time, the drive roller cannot drive the scraper to move up and down, meaning that there is no mutual friction scraping action between the scraper and the cleaning body, and the transmission unit 4 enters a waiting state. The clearance part 74 has a groove structure. When an external force is applied in the opposite direction to the dial 71, causing the locking member 72 to disengage from the meshing teeth 73, and the locking member 72 enters the corresponding position of the clearance part 74, the meshing teeth on the locking member 72 are inside the clearance part 74, and they do not interact with the drive roller. The drive roller can rotate freely, so the scraper can move up and down under the drive of the drive roller (here, up and down is defined as...). Figure 28 (Using the direction shown as an example) The active scraping cleans the object, and the transmission generates 4, entering the working state.

[0128] Another function of the biting teeth 73 is to better transmit the force of the wiping material to the drive roller, allowing the drive roller to rotate around its own axis 462. In this structure, both the drive roller and the scraper can be understood as the movable part 40 of the transmission unit 4. The scraper can be understood as the concave and convex structure on the movable part 40. Specifically, in this embodiment, the scraper can be a mesh structure, and the cleaning material is transmitted from the gaps to the wiping material.

[0129] In this embodiment, the wringer 1 and the cavity 3 are connected together. That is to say, the cavity 3 is not an independent component, but can be generally understood as a part of the structure corresponding to the storage of the cleaning body.

[0130] Example 6

[0131] The difference between this embodiment and Embodiment 1 is that the structure of the transmission unit 4 is different.

[0132] 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 disposed facing the squeezing channel 11, and the second part 45 is opposite to the first part 44. The two are located on opposite sides of the cleaning body. The cleaning body in the cavity 3 can move relative to the squeezing frame 1 under the drive of the second part 45, so that the cleaning body can contact or move away from the first part 44 of the transmission unit 4. Specifically, the cleaning body can move inward and outward under the action of the second part 45.

[0133] The structure of the first part 44 is similar to that of Embodiment 1. It is a transmission roller structure that is rotatably connected to the dewatering frame 1 or the cavity 3. Further details will not be provided. In this embodiment, the dewatering frame 1 and the cavity 3 are connected together. That is to say, the cavity 3 is not an independent component; it can be generally understood as part of the structure corresponding to the storage of the cleaning body, and there is no clear boundary between it and the dewatering frame 1.

[0134] The second part 45 includes a lifting member 451 and a lifting member 452 rotatably connected to the cavity 3 or the squeezing frame 1, a movable member 453 connected to the lifting member 451, a movable member 454 connected to the lifting member 452, and a force-applying member 455. The lifting members 451 and 452 extend the entire width of the extrusion device and are generally rod-shaped. Crucially, both the lifting members 451 and 452 are equipped with lifting levers 450, and the lifting member 451 is also connected to an extension arm 459.

[0135] There are at least two movable parts 453, located at both ends of the lifting part 451 and connected to it at an angle. Similarly, there are at least two movable parts 454, located at both ends of the lifting part 452 and connected to it at an angle. Movable parts 453 are provided with vertical sliding columns 456, and movable parts 454 are provided with track grooves 457. After assembly, the sliding columns 456 fall into the track grooves 457.

[0136] like Figure 34 As shown, the force-applying component 455 has an arc-shaped slide rail 458. When an external force is applied to cause the force-applying component 455 to translate relative to the extrusion device, the arc-shaped slide rail 458 drives the extension arm 459 to move, causing the lifting component 451 to rotate, which in turn drives the lifting lever 450 to rotate. At this time, the sliding column 456 moves in the track groove 457, and the lifting lever 450 on the lifting component 452 also rotates. Therefore, the lifting components 451 and 452 cooperate to lift the cleaning body away from the first part 44, at which time the transmission unit 4 enters the waiting state; or the lifting components 451 and 452 cooperate to move the cleaning body closer to the first part 44, at which time the transmission unit 4 enters the working state.

[0137] In this embodiment, the positioning component 7 can be a slot structure set at both ends of the arc-shaped slide rail 458, which is equivalent to the positioning component 7 and the transmission unit 4 being limited to each other to limit it to the working state or the waiting state. No specific limitation is made.

[0138] Example 7

[0139] like Figure 35 , Figure 36 As shown, in this embodiment, both the transmission unit 4 and the extruder 2 are disposed on the cavity 3, which is rotatably connected to the dewatering frame 1, forming a dewatering channel 11 between the dewatering frame 1 and the cavity 3.

[0140] Applying external force to knob 13 causes cavity 3 to rotate relative to wringer 1. When squeezer 2 rotates to face wringer channel 11, transfer unit 4 is located away from wringer channel 11; conversely, when transfer unit 4 faces wringer channel 11, squeezer 2 is located away from wringer channel 11. In other embodiments, transfer unit 4 can also be located on the upper side, i.e., the side of transfer unit 4 forms a 90° angle with the side of squeezer 2. In other words, squeezer 2 and transfer unit 4 are not simultaneously in operation. When squeezer 2 presses against the wiping material, transfer unit 4 enters a waiting state; when transfer unit 4 is in operation, squeezer 2 is not in use. Cavity 3 rotates squeezer 2 and transfer unit 4 relative to wringer 1, allowing transfer unit 4 to switch between operating and waiting states.

[0141] The specific structure of transmission unit 4 is similar to that of Embodiment 1, and will not be described again.

[0142] Example 8

[0143] like Figures 37-39 As shown, the squeezing element 2 and the cavity 3 are fixed relative to each other on the wringing frame 1. The transmission unit 4 is located on the side of the cavity 3 facing the wringing channel 11, and the squeezing element 2 also faces the wringing channel 11. The squeezing element 2 and the transmission unit 4 are arranged vertically, so they can simultaneously squeeze the wiping material from the flat mop 9. Relatively speaking, the squeezing element 2 is slightly closer to the wringing channel 11, and the transmission unit 4 is slightly farther away from the wringing channel 11. The wringing frame 1 is also provided with a blocking unit 5. The blocking unit 5 can pass through the squeezing element 2 and move to the opposite side of the transmission unit 4. In other words, the blocking unit 5 can pass through the squeezing element 2 and move 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 can also not pass through the squeezing element 2, but can pass through the squeezing element 2 and the transmission unit 4, or the blocking unit 5 can move to be located between the wiping material and the transmission unit 4, or the blocking unit 5 can move between the cleaning body and the transmission unit 4. There are no specific restrictions. The ultimate purpose is to isolate the transmission unit 4 from the wiping material.

[0144] Alternatively, the extruder 2 can be fixedly connected to the wringer 1, and the blocking unit 5 can move from below the extruder 2 to the opposite side of the transmission unit 4, thus isolating the transmission unit 4 from the wiping material. Alternatively, the extruder 2 can be fixedly connected to the wringer 1, with a gap between the extruder 2 and the wringer 1, allowing the blocking unit 5 to move through this gap to the opposite side of the transmission unit 4. In the above structures, the blocking unit 5 moves from top to bottom 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 directly opposite it; there are no specific limitations. The blocking unit 5 can be a plate-like structure capable of certain deformation but also possessing a certain rigidity; there are no specific limitations.

[0145] Of course, the aforementioned extrusion component 2 can also be movably connected to the dewatering frame 1, and there are no specific restrictions.

[0146] During use, when only the squeezing part 2 is needed, the blocking unit 5 is moved to the opposite side of the transmission unit 4 so that the cleaning material in the cavity 3 will not be transmitted to the wiping material of the flat mop 9 through the transmission unit 4. At this time, the transmission unit 4 enters the waiting state. When the cleaning material is needed, the blocking unit 5 is moved back so that both the transmission unit 4 and the squeezing part 2 can come into contact with the wiping material of the flat mop 9. At this time, the transmission unit 4 enters the working state.

[0147] Example 9

[0148] In this embodiment, unlike in embodiment one, the cavity 3 and the extruder 2 are movably connected to the dewatering frame 1, and the transmission unit 4 is located on the side of the cavity 3 facing the dewatering channel 11. Under the action of external force, the relative movement of the cavity 3 and the dewatering frame 1, and the relative movement of the extruder 2 and the dewatering frame 1 can be realized respectively.

[0149] When the squeezing element 2 needs to squeeze the wiping material, it extends relative to the wringer 1. At this time, the transmission unit 4 can retract into the wringer 1, meaning that only the squeezing element 2 squeezes the wiping material within the wringing channel 11. When the transmission unit 4 needs to contact the wiping material, it extends relative to the wringer 1. At this time, the squeezing element 2 can retract into the wringer 1, meaning that only the transmission unit 4 contacts the wiping material within the wringing channel 11. Alternatively, both the squeezing element 2 and the transmission unit 4 can extend relative to the wringer 1, so that both the squeezing element 2 and the transmission unit 4 can function when the flat mop 9 is pulled up and down within the wringing channel 11.

[0150] The structure of the transmission unit 4 is the same as that of Embodiment 1. The structure of the drive cavity 3 and the extruder 2 moving relative to the dewatering frame 1 can also be similar to that of Embodiment 1, and will not be described in detail here.

[0151] Example 10

[0152] In this embodiment, at least a portion of the drive component 6 translates and rotates, thereby moving the cavity 3 relative to the squeezing frame 1 so that the cavity 3 moves closer to or further away from the squeezing channel 11.

[0153] Specifically, the drive assembly 6 includes a paddle with straight teeth, a gear meshing with the straight teeth of the paddle, and a movable member with straight teeth, the straight teeth of which also mesh with the paddle. Simultaneously, the movable member is connected to the cavity 3. Thus, when an external force is applied to the paddle to cause it to translate, the straight teeth of the paddle drive the gear to rotate, which in turn moves the movable member, causing the cavity 3 to move closer to or further away from the squeezing channel 11, thereby switching the transmission unit 4 between a working state and a waiting state.

[0154] The other structures are the same as in Embodiment 1, and will not be described again.

[0155] Example 11

[0156] A hands-free flat mop includes a flat mop 9 with a wiping agent, a mop handle 91 rotatably connected to the flat mop 9, and a squeezing device with any of the structures in Embodiments 1 to 10 described above.

[0157] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
