Description

Technical Field

[0001] This utility model relates to the field of household appliances, and in particular to a wringer, a wringing mechanism, a mop, and a mop bucket. Background Technology

[0002] The wringing mechanism is essential for cleaning or wringing water from a mop. It generally consists of a main body and a scraping component, which can be a squeegee, wringing roller, or similar structure. In traditional technology, the rotating shaft and scraping part of the wringing roller are either molded separately or as a single piece. With separately molded wringing rollers, the scraping part and the rotating shaft may not rotate synchronously during cleaning or wringing, leading to slippage and reduced cleaning and wringing efficiency. With one-piece molded wringing rollers, the rotating shaft and scraping part must be manufactured in the same mold, resulting in a complex mold design. Complex molds are prone to defects such as incomplete filling, air holes, and flash. Defects in any part can lead to the scrapping of the entire workpiece, resulting in a high defect rate and increased production costs. Utility Model Content

[0003] This utility model provides a wringer, a wringing mechanism, a mop, and a mop bucket, which at least solves the problems of high defect rate and high production cost when the wringer is an integrated type, and the problem of low cleaning and wringing efficiency when the wringer is a separate type, where the scraping part is prone to slipping.

[0004] In a first aspect, this utility model provides a wringing roller, disposed on a wringing mechanism, for washing and / or wringing water from a mop board moving within the wringing mechanism, the wringing roller comprising:

[0005] A rotating shaft, with both ends of which are mounted on the dewatering mechanism;

[0006] The scraping part is detachably disposed on the outer periphery of the rotating shaft, and after the rotating shaft and the scraping part are assembled, the rotating shaft and the scraping part stop rotating in the circumferential direction.

[0007] This utility model provides a wringer roller with a separate rotating shaft and scraping part, simplifying the mold structure and reducing production difficulty, defect rate, and production cost. During assembly, the scraping part is detachably mounted on the outer periphery of the rotating shaft. When the scraping part wears due to long-term friction or the rotating shaft becomes bent and damaged, it is not necessary to replace the entire wringer roller; only the scraping part or rotating shaft needs to be replaced, making replacement and maintenance more convenient and reducing operating costs. Furthermore, the rotating shaft and scraping part are circumferentially anti-rotating after assembly, ensuring synchronous rotation between the scraping part and the rotating shaft and preventing slippage. This allows the scraping part to stably and evenly clean and wring water from the mop board, thus guaranteeing scraping efficiency and effect. This solves the problems of complex mold design, high defect rate, and high production difficulty and cost associated with one-piece wringer rollers, as well as the problem of slippage and non-rotation of the scraping part in two-piece wringer rollers, which affects scraping efficiency and effect.

[0008] In one optional embodiment, the scraping part is axially hollow, the outer wall of the rotating shaft has a limiting structure, the inner wall of the scraping part has a mating structure that cooperates with the limiting structure, the rotating shaft passes through the hollow area of ​​the scraping part, and the limiting structure and the mating structure cooperate to prevent the rotating shaft from rotating circumferentially with the scraping part.

[0009] The scraping section features an axially hollow design with a mating structure on its inner wall. The outer wall of the rotating shaft is designed as a limiting structure that mates with the mating structure. The rotating shaft passes through the hollow area of ​​the scraping section to achieve axial assembly. The shapes of the limiting structure and the mating structure are interlocked to prevent the rotating shaft and the scraping section from rotating relative to each other in the circumference. This ensures that the scraping section will not slip during the cleaning and wringing of the mop board.

[0010] In one optional embodiment, one of the limiting structure and the mating structure is a limiting protrusion and the other is a limiting groove. The limiting protrusion and the limiting groove cooperate to prevent the rotating shaft from rotating circumferentially with the scraping part.

[0011] When the rotating shaft enters the hollow area of ​​the scraping part, the limiting protrusion and the limiting groove fit together. The limiting groove forms a circumferential constraint on the limiting protrusion, thereby achieving circumferential anti-rotation between the rotating shaft and the scraping part. While ensuring the reliability of the anti-rotation function, it also has the advantages of simple structure and convenient assembly.

[0012] In one optional embodiment, there are four limiting protrusions, making the rotating shaft have a cross-shaped structure. The hollow area of ​​the scraping part is a cross-shaped channel that cooperates with the cross-shaped structure. The rotating shaft passes through the hollow area of ​​the scraping part. The cross-shaped structure and the cross-shaped channel are interlocked to prevent the rotating shaft and the scraping part from rotating circumferentially.

[0013] The four limiting protrusions on the outer wall of the rotating shaft are perpendicular to each other, making the rotating shaft have a cross-shaped structure. Correspondingly, the hollow area of ​​the scraping part is a cross-shaped channel that matches the cross-shaped structure. When the rotating shaft enters the hollow area of ​​the scraping part, the cross-shaped structure and the cross-shaped channel can fit together precisely, providing anti-rotation constraint forces in multiple directions. The circumferential torque is evenly distributed on the four limiting protrusions, which more effectively prevents circumferential rotation between the rotating shaft and the scraping part. Moreover, the four limiting protrusions can reduce the wear or damage of a single limiting protrusion due to excessive local force, thus extending the service life of the squeezing roller.

[0014] In one optional embodiment, the limiting structure is a non-cylindrical structure composed of a plane and / or a curved surface, and the mating structure is a non-circular channel that matches the shape of the limiting structure; the non-cylindrical structure and the non-circular channel are interlocked to prevent the rotating shaft from rotating circumferentially with the scraping part.

[0015] The outer wall of the rotating shaft is designed as a non-cylindrical structure formed by a plane, a curved surface, or a combination of both. The inner wall of the hollow area of ​​the scraping part is designed as a non-circular channel that matches the non-cylindrical structure of the rotating shaft. In this way, when the rotating shaft enters the scraping part, the complementary shapes of the non-cylindrical structure and the non-circular channel form an interlocking contour, achieving the effect of preventing the rotating shaft and the scraping part from rotating in the circumferential direction. At the same time, it also has the advantages of flexible and diverse structure and convenient assembly.

[0016] In one optional embodiment, the rotating shaft structure is one of the following: a convex polygon structure, a concave polygon structure, or an elliptical structure; the hollow region structure is one of the following: a convex polygon channel, a concave polygon channel, or an elliptical channel.

[0017] The rotating shaft can be a convex polygon structure such as a triangle, quadrilateral, or regular hexagon, or a concave polygon structure such as a pentagon or hexagon, or a racetrack-shaped or elliptical structure. The contour of the rotating shaft and the shape of the hollow area complement each other to form contour interlocking. While ensuring the reliability of shape interlocking, it realizes differentiated design and meets diverse user needs.

[0018] In one optional embodiment, the scraping section includes multiple independent scrapers, which are sequentially arranged on the outside of the rotating shaft along the circumference of the rotating shaft. After the rotating shaft and the multiple scrapers are assembled, the rotating shaft and the scraping section stop rotating circumferentially.

[0019] The scraping section is designed with multiple independent scrapers, which reduces mold complexity and further lowers production difficulty and costs. During assembly, the multiple scrapers are detachably mounted sequentially to the outer circumference of the rotating shaft. When a scraper becomes worn or damaged, the entire scraping section does not need to be replaced; only the individual scraper needs to be replaced, making replacement and maintenance more convenient and further reducing operating costs. Furthermore, the rotating shaft and multiple scrapers are circumferentially anti-rotating, ensuring that the scrapers rotate synchronously with the shaft and preventing slippage. This allows the scrapers to stably and evenly clean and wring water from the mop board, thus guaranteeing scraping efficiency and effectiveness.

[0020] In one optional embodiment, the dewatering roller further includes: two mounting plates, respectively disposed at both ends of the rotating shaft, and a plurality of fixing grooves are provided on the opposite side of the two mounting plates, the plurality of fixing grooves being arranged radially around the mounting plates;

[0021] The two ends of the plurality of scrapers are respectively disposed in the plurality of fixing grooves of the two mounting plates. After the rotating shaft and the plurality of scrapers are assembled through the mounting plates, the rotating shaft and the scraping part are circumferentially prevented from rotating.

[0022] Two mounting plates are fixed to both ends of the rotating shaft. Multiple fixing grooves are designed on the inner side of the scraper, with the shape of the grooves matching the ends of the scraper. Each scraper's ends are inserted into the fixing grooves of the two mounting plates, achieving circumferential anti-rotation and axial fixation of each scraper, thus enabling synchronous rotation of the scraping unit and the rotating shaft. Furthermore, the fixing grooves on the mounting plates at both ends further secure each scraper, effectively preventing circumferential swaying and axial movement caused by the pressure of the wiping material during cleaning or wringing. This allows the scraper to clean or wring water more stably and evenly, ensuring scraping efficiency and effectiveness.

[0023] In one alternative embodiment, each scraper has a plurality of scraping ridges arranged on the side of the scraper opposite to the rotation axis, and the plurality of scraping ridges of the plurality of scrapers form a non-smooth circumferential extrusion surface of the dewatering roller.

[0024] Multiple scraping ridges are designed on a single scraper, and the combination of all the scraping ridges forms a non-smooth circumferential extrusion surface of the wringer roller. When the mop blade passes over the extrusion surface, the scraping ridges can directly scrape away dirt and moisture absorbed by the surface of the mop. The dirt and moisture can flow out from the gaps between the scraping ridges, further improving scraping efficiency and effect. Furthermore, the design of the scraping ridges effectively prevents slippage in the scraping section, ensuring that the scraping section rotates synchronously with the rotating shaft.

[0025] In one optional embodiment, the scraper has a Y-shaped structure, each scraper having two scraping ridges, the two ends of the intersection of the two scraping ridges being respectively engaged in the fixing grooves of the two mounting plates.

[0026] The scraper is designed with a Y-shaped structure. The Y-shaped scrapers are arranged circumferentially along the rotation axis to form a non-smooth circumferential extrusion surface of the squeezing roller. The two ends of each scraper intersection are engaged in the fixing groove of the mounting plate to achieve stable fixation of the scraper. This makes the circumferential anti-rotation assembly connection of the scraping part formed by multiple scrapers, the rotation axis and the mounting plate more stable, which enhances the stability of the squeezing roller structure. In addition, the Y-shaped scraper is easy to fix and can also effectively prevent the scraping edge from deforming under the pressure of the wiping material.

[0027] In one alternative embodiment, the scraper has a T-shaped structure, with the tips of the plurality of scrapers facing the rotating shaft, and the fixing groove is a T-shaped groove that cooperates with the scraper structure.

[0028] The individual scraper is designed with a T-shaped structure, with multiple scraping ridges arranged on the side of the long horizontal blade facing away from the rotation axis. The scraping ridges of all the scrapers form a non-smooth circumferential extrusion surface of the squeezing roller, further improving scraping efficiency and effect. Furthermore, both ends of each scraper are inserted into the T-shaped grooves of two mounting plates. This multi-directional constraint further improves assembly stability and circumferential anti-rotation effect, effectively preventing the scraper from rotating circumferentially or moving axially.

[0029] In one optional embodiment, the outer wall of the rotating shaft is provided with a plurality of grooves along the axial direction, and one end of the plurality of scrapers near the rotating shaft is disposed in the plurality of grooves.

[0030] Each scraper blade has its end near the rotating shaft abutting against multiple grooves on the outer wall of the rotating shaft. When the mop pad presses against the scraper blade, the rotating shaft provides support, preventing the scraper blade from bending towards the rotating shaft, affecting the scraping effect, or even deforming, thus improving scraping efficiency and effect. Furthermore, the scraper blade's end near the rotating shaft being positioned in a groove on the rotating shaft further enhances the stability of the wringer roller structure and improves the circumferential anti-rotation effect.

[0031] In one optional embodiment, the two mounting plates are provided with mounting grooves on opposite sides, and a plurality of fixing grooves are arranged radially around the mounting grooves. The two ends of the rotating shaft are non-cylindrical structures, and the sidewalls of the mounting grooves are structures that cooperate with the non-cylindrical structures. The two ends of the rotating shaft are respectively inserted into the mounting grooves of the two mounting plates so that the rotating shaft and the mounting plates circumferentially stop rotating.

[0032] The two ends of the rotating shaft are inserted into the mounting grooves of the mounting plate, and the two ends of the rotating shaft are complementary in shape to the mounting grooves to achieve circumferential anti-rotation and axial limiting. This achieves two- and two-dimensional anti-rotation between the scraping part, the rotating shaft and the mounting plate, making the anti-rotation function more reliable and further improving the overall stability of the squeezing roller structure.

[0033] Secondly, this utility model provides a water-squeezing mechanism, comprising:

[0034] A seat body having two opposing first sidewalls and an abutting sidewall located between the two first sidewalls;

[0035] A housing having two opposing second sidewalls and a sidewall located between the two second sidewalls;

[0036] The two first sidewalls are respectively connected to the second sidewall located on the same side to form the two constraint sidewalls of the water squeezing mechanism, and the two constraint sidewalls are provided with movable tracks;

[0037] The scraping component includes the water-squeezing roller described in any of the above embodiments, with both ends of the water-squeezing roller respectively disposed in the movable tracks of the two constrained sidewalls.

[0038] The water-squeezing mechanism provided by this utility model includes a base, a housing, and a water-squeezing roller. The base and housing are assembled to form the constraint sidewall of the water-squeezing mechanism. Both ends of the water-squeezing roller are positioned in movable tracks opened on the constraint sidewall. The water-squeezing roller moves within these tracks to clean and squeeze water from the mop board. The rotating shaft and scraping part of the water-squeezing roller are separately formed, simplifying the mold structure and reducing production difficulty, defect rate, and production costs. During assembly, the scraping part is detachably mounted on the outer periphery of the rotating shaft. When the scraping part wears due to long-term friction or the rotating shaft becomes bent and damaged, it is not necessary to replace the entire water-squeezing roller; only the scraping part or the rotating shaft needs to be replaced. This makes replacement and maintenance more convenient and reduces operating costs. Furthermore, the rotating shaft and scraping part are circumferentially anti-rotating after assembly, ensuring that the scraping part rotates synchronously with the rotating shaft and preventing slippage. This allows the scraping part to stably and evenly clean and squeeze water from the mop board, thus ensuring scraping efficiency and effectiveness. This invention solves the problems of complex mold design, high defect rate, high production difficulty and high cost of one-piece molded squeezing rollers, as well as the problem of slippage and non-rotation of the scraping part of split molded squeezing rollers, which affects the scraping efficiency and scraping effect.

[0039] In one alternative embodiment, as the mop board moves in the squeezing opening formed between the wringer and the abutting sidewall, the wiping material from the mop board drives the wringer to roll along the movable track, and when the wringer rolls to the first end of the movable track, an anti-rotation structure provided at the first end stops the wringer from rotating.

[0040] The material being wiped by the mop board moves up and down in the squeezing orifice, driving the wringer roller to roll in the movable track. When the wringer roller rolls to the first end of the movable track, it stops rolling. An anti-rotation structure located at the first end contacts the end of the wringer roller, mechanically restraining it from rotating. The stationary wringer roller, in conjunction with the squeezing orifice formed by its contact with the side wall, achieves static clamping, scraping, and squeezing of the material, enhancing the scraping efficiency and effect of the wringer roller.

[0041] In one optional embodiment, the anti-rotation structure is a boss provided at the first end, and the two ends of the squeezing roller have blocking portions; when the squeezing roller rolls to the first end, the boss and the blocking portions cooperate to stop the squeezing roller from rotating.

[0042] When the squeezing roller rotates to the first end, the blocking part at the end of the squeezing roller is interlocked with the boss set at the first end, which drives the squeezing roller to stop rotating. The structure that achieves the anti-rotation function is simple and highly reliable.

[0043] In one optional embodiment, the two ends of the squeezing roller are cross-shaped structures, and the two adjacent arms of the cross-shaped structure form the blocking part. When the squeezing roller rolls to the first end, the boss engages between the two adjacent arms to stop the squeezing roller from rotating.

[0044] The two ends of the squeezing roller are designed with a cross-shaped structure, and the adjacent arms form a blocking part and a boss to form an anti-rotation structure, so as to achieve shape interlocking and achieve a more precise and stable anti-rotation effect.

[0045] In one optional embodiment, the anti-rotation structure is a pawl disposed at the first end, and the two ends of the squeezing roller have ratchet structures; when the squeezing roller rolls to the first end, the pawl engages with the tooth groove of the ratchet structure to stop the squeezing roller from rotating.

[0046] When the squeezing roller rotates to the first end, the pawl located at the first end engages with the tooth grooves of the ratchet structure at both ends of the squeezing roller, causing the squeezing roller to stop rotating. The structure that achieves the anti-rotation function is simple, easy to manufacture, low in cost, and highly reliable.

[0047] In one optional embodiment, when the mop board moves forward, the wiping material of the mop board drives the wringer to roll forward along the movable track until the wringer rolls forward to the first end of the movable track, at which point an anti-rotation structure provided at the first end stops the wringer from rotating forward.

[0048] When the mop board moves in the reverse direction, the wiping material of the mop board drives the wringer to roll in the reverse direction along the movable track until the wringer rolls in the reverse direction to the second end of the movable track, at which point the wiping material drives the wringer to continue to rotate in the reverse direction at the second end.

[0049] The mop board moves in both directions within the squeezing nozzle, driving the wringer roller to roll in both directions along a movable track. When the mop board moves forward, causing the wringer roller to roll forward to the first end of the movable track, the wringer roller stops rolling. An anti-rotation structure at the first end prevents the wringer roller from rotating, thus improving cleaning efficiency and effectiveness. When the mop board moves backward, driving the wringer roller to roll backward to the second end of the movable track, the wringer roller stops rolling. The wiping material causes the wringer roller to continue rotating at the second end, enabling the wringing mechanism to achieve both rolling squeezing and unidirectional anti-rotation functions.

[0050] In one alternative implementation, the movable tracks on the two constrained sidewalls are tilted.

[0051] When the mop board moves forward, the wiping material of the mop board drives the wringer to roll along the movable track in the direction of decreasing the squeezing opening; when the mop board moves in the reverse direction, the wiping material of the mop board drives the wringer to roll along the movable track in the direction of increasing the squeezing opening.

[0052] The inclined movable track has a smaller distance between the first end and the side wall than the second end, which makes the squeezing opening smaller as the mop board moves forward, thus improving the scraping efficiency and effect; as the mop board moves backward, the squeezing opening becomes larger, making it easier for the mop board to easily detach from the squeezing opening.

[0053] Thirdly, this utility model provides a mop, comprising:

[0054] The mop handle, mop board, and mop handle;

[0055] The wringing mechanism is slidably connected to the mop handle, and the mop plate is rotatably connected to one end of the mop handle;

[0056] The dewatering mechanism is the dewatering mechanism described in any of the above embodiments.

[0057] Fourthly, this utility model provides a mop bucket, comprising:

[0058] A barrel body and a water-squeezing mechanism disposed at the opening of the barrel body, wherein the water-squeezing mechanism is the water-squeezing mechanism described in any of the above embodiments. Attached Figure Description

[0083] The embodiments of this utility model are described in detail below.

[0085] Furthermore, features specified as "first" or "second" may explicitly or implicitly include one or more of the same feature, used to distinguish and describe features, without any order or distinction of importance.

[0086] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0087] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0088] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0089] The following is in conjunction with the appendix Figures 1 to 10 This invention describes the water-squeezing roller, water-squeezing mechanism, mop, and mop bucket of this utility model.

[0090] Figure 1 This is a schematic diagram of the structure of a dewatering roller provided in an exemplary embodiment of this utility model, as shown below. Figure 1 As shown, the wringer 100 provided by this utility model is disposed on the wringer mechanism 10 and is used to clean and / or wring water from the mop plate moving in the wringer mechanism 10. Figures 1 to 7 As shown, the dewatering roller 100 includes a rotating shaft 101 and a scraping section 102. The rotating shaft 101 and the scraping section 102 of the dewatering roller 100 provided by this utility model are formed separately, requiring separate molds. Compared with the single set of molds required for an integrally formed dewatering roller, this simplifies the mold structure, reduces the difficulty and complexity of mold design, reduces production processing difficulty, decreases the defect rate, and lowers production costs. It solves the problems of complex mold design, high defect rate, and high production difficulty and cost associated with integrally formed dewatering rollers.

[0091] In this invention, the rotating shaft 101 and the scraping part 102 are formed separately, and the rotating shaft 101 and the scraping part 102 can be made of different materials. For example, the rotating shaft 101 can be made of a high-strength, wear-resistant material to ensure stable rotation during long-term use. The scraping part 102 can be made of a suitable material depending on the material being wiped. Specifically, it can be made of softer materials such as silicone or cotton, or harder materials such as plastic or steel plate; this embodiment does not impose a specific limitation.

[0092] Both ends of the rotating shaft 101 are mounted on the dewatering mechanism 100, and the scraping part 102 is detachably mounted on the outer periphery of the rotating shaft 101. By using a detachable assembly method to mount the scraping part 102 on the outer periphery of the rotating shaft 101, when the scraping part 102 wears due to long-term friction or the rotating shaft 101 becomes bent or damaged, it is not necessary to replace the entire dewatering roller 100; only the scraping part 102 or the rotating shaft 101 needs to be replaced. This makes replacement and maintenance more convenient and reduces operating costs. It solves the problem that one-piece molded dewatering rollers require replacing the entire roller, resulting in high maintenance costs.

[0093] After the rotating shaft 101 and the scraping part 102 are assembled, the rotating shaft 101 and the scraping part 102 are prevented from rotating circumferentially. The wringing roller 100 provided by this utility model, with its rotating shaft 101 and scraping part 102 preventing circumferential rotation after assembly, ensures that the scraping part 102 and the rotating shaft 101 can rotate synchronously during the scraping of items on the mop board, preventing the scraping part 102 from slipping. This allows the scraping part 102 to stably and evenly and effectively scrape and squeeze the items on the mop board, achieving the effect of removing stains and excess water from the items, ensuring scraping efficiency and effect. This solves the problem of the scraping part of the wringing roller easily slipping and failing to rotate, affecting the scraping efficiency and effect of the items being wiped.

[0094] In some embodiments, the scraping part 102 is axially hollow, the outer wall of the rotating shaft 101 has a limiting structure, and the inner wall of the scraping part 102 has a mating structure that cooperates with the limiting structure. The rotating shaft 101 passes through the hollow area of ​​the scraping part 102, and the limiting structure and the mating structure cooperate to prevent the rotating shaft 101 from rotating circumferentially with the scraping part 102. The scraping part 102 is axially hollow, and the inner wall of the hollow part is designed with a mating structure. The outer wall of the rotating shaft 101 is designed as a limiting structure that cooperates with the mating structure. During assembly, one end of the rotating shaft 101 is inserted into the hollow area of ​​the scraping part 102 to achieve axial assembly of the rotating shaft 101 and the scraping part 102. After assembly, the limiting structure of the rotating shaft 101 and the matching structure of the scraping part 102 are interlocked, so that the rotating shaft 101 and the scraping part 102 cannot rotate relative to each other in the circumferential direction, ensuring that the scraping part 102 will not slip during the process of cleaning and squeezing the mop board with the wringer 100.

[0095] In one implementation, one of the limiting structure and the mating structure is a limiting protrusion, and the other is a limiting groove. The limiting protrusion and the limiting groove cooperate to prevent the rotation of the rotating shaft 101 and the scraping part 102 from rotating circumferentially. When the rotating shaft 101 enters the hollow area of ​​the scraping part 102, the limiting protrusion and the limiting groove engage, and the limiting groove forms a circumferential constraint on the limiting protrusion, thereby preventing the rotation of the rotating shaft 101 and the scraping part 102 from rotating circumferentially. While ensuring the reliability of the anti-rotation function, it also has the advantages of simple structure and convenient assembly.

[0096] In one example, the limiting structure and the mating structure can be respectively arranged along the axial directions of the rotation shaft 101 and the scraping part 102. Exemplarily, the limiting structure is a limiting protrusion formed in the axial direction of the rotation shaft 101, and the mating structure is a limiting groove formed in the axial direction of the scraping part 102, with the limiting groove and the limiting protrusion having complementary shapes. The limiting protrusion and the limiting groove can be square, trapezoidal, triangular, or other structures, and the number of limiting protrusions and limiting grooves can be one or more. In this embodiment, the shape and number of limiting protrusions and limiting grooves are not specifically limited.

[0097] like Figure 2 and Figure 3 As shown, there are four limiting protrusions, which are perpendicular to each other, making the rotating shaft 101 have a cross-shaped structure. The hollow area of ​​the scraping part 102 is a cross-shaped channel that cooperates with the cross-shaped structure. The rotating shaft 101 passes through the hollow area of ​​the scraping part 102. The cross-shaped structure and the cross-shaped channel interlock to prevent the rotating shaft 101 and the scraping part 102 from rotating circumferentially. When the rotating shaft 101 enters the hollow area of ​​the scraping part 102, the cross-shaped structure and the cross-shaped channel can cooperate precisely to provide anti-rotation constraint forces in multiple directions. The circumferential torque is evenly distributed on the four limiting protrusions, which more effectively prevents circumferential rotation between the rotating shaft 101 and the scraping part 102. Moreover, the four limiting protrusions can reduce the wear or damage of individual limiting protrusions caused by excessive local force, thus extending the service life of the squeezing roller 100.

[0098] In another example, the limiting structure and the mating structure can be respectively arranged along the circumference of the rotating shaft 101 and the scraping part 102. Exemplarily, the limiting structure is a limiting protrusion formed at one end of the rotating shaft 101, which is discontinuous in the circumferential direction. The mating structure is a limiting groove formed at the same end of the scraping part 102 on the same side, with the limiting groove and the limiting protrusion having complementary shapes in the circumferential direction. For example, the limiting protrusion can be a C-shape, a half-bracket shape, a protrusion, etc., and the corresponding limiting groove can be a C-shape, a half-bracket shape, a groove, etc. During assembly, the end of the rotating shaft 101 without the limiting protrusion is inserted into the end of the scraping part 102 with the limiting groove, and the limiting protrusion at the other end of the rotating shaft 101 is embedded in the limiting groove of the scraping part 102 to complete the assembly.

[0099] In another implementation, the limiting structure can be a non-cylindrical structure composed of a plane, a curved surface, or a combination of both, and the mating structure is a non-circular channel that matches the shape of the limiting structure. The interlocking fit between the non-cylindrical structure and the non-circular channel prevents the rotation of the rotating shaft 101 and the scraping part 102 from rotating circumferentially. Thus, when the rotating shaft 101 enters the scraping part 102, the complementary shapes of the non-cylindrical rotating shaft 101 and the non-circular scraping part 102 form a contour interlock, achieving the effect of preventing the rotation of the rotating shaft 101 and the scraping part 102 from rotating circumferentially, while also having the advantages of flexible and diverse structures and convenient assembly.

[0100] In one example, the non-cylindrical structure of the rotating shaft 101 can be one of the following: a convex polygon structure, a concave polygon structure, or an elliptical structure. Correspondingly, the non-circular channel structure of the hollow area of ​​the scraping part 102 can be one of the following: a convex polygon channel, a concave polygon channel, or an elliptical channel. For example, the rotating shaft 101 can be a convex polygon structure such as a triangular prism, a square prism, or a hexagonal prism; it can also be a concave polygon structure with a V-shaped, pentagonal, hexagonal, or irregular cross-section; or it can be a structure with a curved or combined straight and curved cross-section, such as an elliptical, U-shaped, racetrack-shaped, or D-shaped structure. The contours of the rotating shaft 101 and the shape of the hollow area of ​​the scraping part 102 complement each other to form contour interlocking, ensuring the reliability of shape interlocking while achieving differentiated design to meet diverse user needs. In practical applications, the rotating shaft 101 and the scraping part 102 can also achieve anti-rotation functionality using other detachable assembly methods such as splines or threads; no specific limitations are made here.

[0101] The scraping section 102 can be as described above. Figure 2 and Figure 3 The single-piece component shown can also be a separate component. For example... Figures 4 to 7 As shown, the scraping section 102 includes multiple independent scrapers 1020. The individual fabrication of multiple scrapers 1020 further simplifies the mold structure, reduces the difficulty and complexity of mold design for the scraping section 102, lowers the manufacturing difficulty of the scraping section, reduces the defect rate, and further reduces production costs. This solves the problems of complex mold design, high defect rate, and high production difficulty and cost associated with one-piece molded scraping sections.

[0102] Multiple scrapers 1020 are sequentially arranged around the outside of the rotating shaft 101. The multiple scrapers 1020 are arranged in sequence to form the scraping section 102 of the squeezing roller 100. During use, if one of the scrapers 1020 is severely worn or damaged, it is not necessary to replace the entire scraping section 102; only the individual scraper needs to be replaced. This makes replacement and maintenance more convenient and further reduces operating costs.

[0103] In some embodiments, the multiple scrapers 1020 can be made of the same material or different materials, and the shapes of the multiple scrapers 1020 can be the same or different. For example, the working area of ​​some scrapers is designed as hard scraping teeth to remove stubborn stains on the wiping object; the working area of ​​some scrapers is designed as soft scraping blades to scrape off excess water on the wiping object; and the working area of ​​some scrapers is designed as brushes to clean foreign objects such as hair attached to the wiping object. These components are combined to form a multi-functional scraping and washing unit 102 that scrapes, squeezes, and brushes. Compared with a single-structure scraping and washing unit 102, the structure of the multi-functional scraping and washing unit 102 can be applied to more complex cleaning scenarios. The working area of ​​the scraper is the area where the scraper contacts the wiping object during the scraping and washing process of the water-squeezing roller 100.

[0104] After the rotating shaft 101 is assembled with multiple scrapers 1020, the rotating shaft 101 and the scraping section 102 are circumferentially prevented from rotating. During assembly, multiple scrapers are sequentially and detachably assembled to the outer periphery of the rotating shaft 101. After the rotating shaft 101 and multiple scrapers 1020 are assembled, they are circumferentially prevented from rotating, ensuring that the multiple scrapers 1020 rotate synchronously with the rotating shaft 101. This prevents the scrapers 1020 from slipping, allowing the scrapers 1020 to stably and evenly clean and wring water from the mop board, thereby ensuring scraping efficiency and cleaning effect.

[0105] In some embodiments, the dewatering roller 100 may further include two mounting plates 103. For example... Figures 4 to 7As shown, two mounting plates 103 are respectively disposed at both ends of the rotating shaft 101. Multiple fixing grooves 1030 are provided on the opposite side of the two mounting plates 101, and these grooves are arranged radially around the mounting plates 103. Multiple scraper blades 1020 are respectively disposed at both ends in the multiple fixing grooves 1030 of the two mounting plates 103. After the rotating shaft 101 and the multiple scraper blades 1020 are assembled through the mounting plates 103, the rotating shaft 101 and the scraping section 102 are circumferentially prevented from rotating. The mounting plates 103 can be circular or polygonal in structure. Two mounting plates 103 are respectively fixed to both ends of the rotating shaft 101. Multiple fixing grooves 1030 are designed on the opposite side of the two mounting plates 103, i.e., the side facing the scraping section 102. These fixing grooves 1030 are radially distributed around the mounting plates, for example, six fixing grooves, evenly distributed at 60° intervals around the circumference of the circular mounting plate 103. Each scraper 1020 has protrusions or pins at both ends that match the fixing grooves 1030. During assembly, the two ends of the scraper 1020 are respectively inserted into the two opposing fixing grooves 1030 of the two mounting plates 103. The circumferential positioning and axial fixation of the scraper 1020 are achieved through the engagement of the grooves and pins. In this embodiment, the scrapers 1020 are further fixed by the fixing grooves 1030 on the mounting plates 103 at both ends of the rotating shaft 101. This effectively prevents the scrapers 1020 from circumferentially swinging and axially moving due to the pressure of the wiping material during cleaning or wringing. This allows the scrapers 1020 to clean or wring water more stably and evenly, ensuring cleaning efficiency and cleaning effect.

[0106] In some embodiments, each scraper 1020 has multiple scraping ridges, such as Figures 4 to 7 As shown, multiple scraping ridges are arranged on the side of the scraper 1020 facing away from the rotating shaft 101, and the multiple scraping ridges of the multiple scraper 1020 form a non-smooth circumferential extrusion surface of the wringer 100. In this embodiment, the wringer 100 has multiple scraping ridges designed on each scraper 1020 included in the scraping section 102, and the combination of all the scraping ridges of the scraper 1020 forms a non-smooth circumferential extrusion surface of the wringer 100. When the mop plate comes into contact with the extrusion surface, the scraping ridges can directly scrape the dirt and moisture absorbed by the surface of the dirt and moisture, which can flow out from the gaps between the scraping ridges, further improving the scraping efficiency and effect. Furthermore, the design of the scraping ridges can more effectively prevent slippage in the scraping section, further ensuring that the scraping section 102 rotates synchronously with the rotating shaft 101.

[0107] In one implementation, the scraper 1020 has a multi-branch tree structure, with each scraper 1020 having multiple scraping ridges. The two ends of the intersection of two adjacent scraping ridges of each scraper 1020 are respectively engaged in the opposing fixing grooves 1030 of two mounting plates 103. For example, the scraper 1020 has a binary tree structure, that is, the scraper 1020 has a... Figure 4 and Figure 5 The Y-shaped structure shown has two scraping ridges for each scraper 1020. The two ends of the intersection of the two scraping ridges are respectively engaged in the fixing grooves 1030 of the two mounting plates 103. Figure 4 The two ends of the intersection of the two scraping edges of the scraper 1020 shown are respectively the first region 1021 and the second region 1022. The first region 1021 and the second region 1022 are respectively inserted into a fixing groove 1030 of a mounting plate 103, and the two fixing grooves 1030 are axially opposite to each other, so as to realize the axial fixed installation of the scraper 1020. The scraper 1020 is designed as a Y-shaped structure. The Y-shaped scrapers are arranged circumferentially along the rotation axis 101 to form a non-smooth circumferential extrusion surface of the squeezing roller 100. The two ends of the intersection of each scraper 1020 are engaged in the fixing groove 1030 of the mounting plate 103 to achieve stable fixation of the scraper 1020. This makes the circumferential anti-rotation assembly connection of the scraping part 102 formed by multiple scrapers 1020, the rotation axis 101 and the mounting plate 103 stronger, enhancing the stability of the squeezing roller 100 structure. In addition, the Y-shaped scraper 1020 is easy to fix and can also effectively prevent the scraping edges from deforming under the pressure of the wiping material.

[0108] In another implementation, the scraper 1020 is shaped as follows: Figure 6 and Figure 7 The illustrated T-shaped structure features multiple scraper blades 1020 with their tips 1023 facing the rotating shaft 101. The fixing groove 1030 on the mounting plate 103 is a T-shaped groove that mates with the scraper blade 1020 structure. Designing a single scraper blade 1020 as a T-shaped structure, multiple scraping ridges are arranged on the side of the long horizontal axis facing away from the rotating shaft 101. All the scraping ridges of the scraper blades 1020 form a non-smooth circumferential extrusion surface of the squeezing roller 100, further improving the scraping efficiency and effect of the squeezing roller 100. Furthermore, the two ends of each scraper blade 1020 are inserted into the T-shaped grooves of the two mounting plates 103. This multi-directional constraint further improves assembly stability and circumferential anti-rotation effect, effectively preventing the scraper blades from rotating circumferentially or moving axially.

[0109] In some embodiments, the outer wall of the rotating shaft 101 is provided with a plurality of grooves 1010 along the axial direction, and the ends of the plurality of scrapers 1020 near the rotating shaft 101 are disposed in the plurality of grooves 1010. The number of grooves 1010 on the rotating shaft 101 can be equal to the number of scrapers 1020, for example, both are 6. A groove 1010 is provided every 60° on the rotating shaft 101. The ends of the scrapers 1020 near the rotating shaft 101 abut against the grooves 1010. In this way, when the mop pad presses the scraper 1020, the abutting rotating shaft 101 applies a supporting force to the scraper 1020 toward the mop pad, effectively preventing the scraper 1020 from bending toward the rotating shaft 101, affecting the scraping effect or even deforming, which helps to further improve the scraping efficiency and scraping effect. Furthermore, one end of the scraper 1020 near the rotating shaft 101 is set in the groove 1010 on the rotating shaft 101, and both ends of the scraper 1020 in the length direction are inserted into the opposite fixing grooves 1030 of the two mounting plates 103, thereby achieving multi-directional constraint on the scraper 1020. This can further enhance the stability of the squeezing roller 100 structure, improve the circumferential anti-rotation effect, and effectively prevent the scraper 1020 from rotating circumferentially or moving axially.

[0110] In some embodiments, mounting grooves 1031 are provided on opposite sides of the two mounting plates 103, and multiple fixing grooves 1020 are radially arranged around the mounting grooves 1031. The two ends of the rotating shaft 101 are non-cylindrical structures, and the sidewalls of the mounting grooves 1031 are structures that mate with the non-cylindrical structures. The two ends of the rotating shaft 101 are respectively inserted into the mounting grooves 1031 of the two mounting plates 103 to prevent the rotating shaft 101 from rotating circumferentially with the mounting plates 103. By inserting the two ends of the rotating shaft 101 into the mounting grooves 1031 of the mounting plates 103, and with the two ends of the rotating shaft 101 and the mounting grooves 1031 having complementary shapes, circumferential rotation prevention and axial limiting are achieved. This achieves two-way and two-way rotation prevention among the scraping part 102, the rotating shaft 101, and the mounting plates 103, making the rotation prevention function more reliable and further improving the overall structural stability of the squeezing roller 100.

[0111] For example, both ends of the rotating shaft 101 can be non-cylindrical structures with the same structure as the part of the rotating shaft 101 that contacts the scraping part 102, such as a cross-shaped structure or... Figure 7 The structure shown is a trapezoidal shape. The mounting groove 1031 can be located at the center of the mounting plate 103. The shape of the sidewall of the mounting groove 1031 can be a structure that mates with a non-cylindrical structure, such as a cross-shaped groove or... Figure 7 The trapezoidal groove shown is used in practical applications. The two ends of the rotating shaft 101 and the mounting groove 1031 can also be other structures that can achieve the anti-rotation function, which are not specifically limited here.

[0112] In some embodiments, the two ends of the rotating shaft 101 are inserted into the mounting grooves 1031 of the mounting plate 103. The mounting grooves 1031 protrude outward from the outside of the mounting plate 103, that is, from the side opposite to the scraping part 102, forming the two ends of the squeezing roller 100. The squeezing roller 100 is fixed to the squeezing mechanism 10 by the two outwardly protruding ends of the mounting plate 103.

[0113] In some embodiments, both ends of the rotating shaft 101 are inserted into the mounting groove 1031 of the mounting plate 103. The mounting groove 1031 is a through hole facing the outside of the mounting plate 103, so that the two ends of the rotating shaft 101 passing through the through hole form the two ends of the squeezing roller 100. The squeezing roller 100 is fixed to the squeezing mechanism 10 by the two ends of the rotating shaft 101 passing through the mounting groove 1031.

[0114] like Figure 1 , Figures 8 to 12 As shown, this utility model provides a dewatering mechanism 10, including: a base 200, a housing 300, and a scraping member 400. The base 200 has two opposing first sidewalls 201 and an abutting sidewall 202 located between the two first sidewalls 201. The housing 300 has two opposing second sidewalls 301 and a setting sidewall 302 located between the two second sidewalls 301. The two first sidewalls 202 are respectively connected to the second sidewalls 302 located on the same side to form two constraint sidewalls of the dewatering mechanism 10, and movable tracks 500 are provided on the two constraint sidewalls. The scraping member 400 includes a dewatering roller 100 provided in any of the above embodiments, with both ends of the dewatering roller 100 respectively disposed in the movable tracks 500 of the two constraint sidewalls.

[0115] like Figure 1 , Figures 8 to 12 As shown, the two first sidewalls 201 of the base 200 are respectively connected to the second sidewall 301 on the same side of the housing 300, forming two constraint sidewalls of the squeezing mechanism 10. The cover plate 600 is placed on the constraint sidewalls. The abutting sidewall 202 of the base 200 forms the abutting sidewall 202 of the squeezing mechanism 10, and the setting sidewall 302 of the housing 300 forms the setting sidewall 302 of the squeezing mechanism 10. The abutting sidewall 202, the setting sidewall 302, and the two constraint sidewalls form the squeezing channel of the squeezing mechanism 10. The scraping member 400 is disposed in the squeezing channel near the setting sidewall 302, and the space between the scraping member 400 and the abutting sidewall 202 forms the squeezing opening. When it is necessary to clean or squeeze the wiped material on the mop board, the wiped material on the mop board is inserted into the squeezing opening and moved up and down. The scraping member 400 scrapes and / or squeezes the wiped material to clean and squeeze it.

[0116] The movable tracks 500 formed on the two constrained sidewalls can be formed on the first sidewall 201, or on the second sidewall 301, or partially on the first sidewall 201 and partially on the second sidewall 301, combined to form the movable tracks 500. The scraping member 400 includes the water-squeezing roller 100 provided in any of the above embodiments, with both ends of the water-squeezing roller 100 respectively disposed in the movable tracks 500 of the two constrained sidewalls.

[0117] This utility model provides a squeezing mechanism, including a base, a housing, and a squeezing roller. The base and housing are assembled to form the constraint sidewall of the squeezing mechanism. Both ends of the squeezing roller are positioned in movable tracks on the constraint sidewall. The squeezing roller moves within these tracks to clean and squeeze water from the mop board. The rotating shaft and scraping part of the squeezing roller are separately formed, simplifying the mold structure and reducing production difficulty, defect rate, and production costs. During assembly, the scraping part is detachably mounted on the outer periphery of the rotating shaft. When the scraping part wears due to long-term friction or the rotating shaft becomes bent and damaged, it is not necessary to replace the entire squeezing roller; only the scraping part or the rotating shaft needs to be replaced, making replacement and maintenance more convenient and reducing operating costs. Furthermore, the rotating shaft and scraping part are circumferentially anti-rotating after assembly, ensuring synchronous rotation between the scraping part and the rotating shaft, preventing slippage of the scraping part. This allows the scraping part to stably and evenly clean and squeeze water from the mop board, thus ensuring scraping efficiency and effectiveness. This invention solves the problems of complex mold design, high defect rate, high production difficulty and high cost of one-piece molded squeezing rollers, as well as the problem of slippage and non-rotation of the scraping part of split molded squeezing rollers, which affects the scraping efficiency and scraping effect.

[0118] In some embodiments, when the mop board moves in the squeezing opening formed between the wringer 100 and the abutting sidewall 202, the wiping material of the mop board drives the wringer 100 to roll along the movable track 500, and when the wringer 100 rolls to the first end 501 of the movable track 500, the anti-rotation structure 503 provided at the first end 501 stops the wringer 100 from rotating.

[0119] When the mop head is inserted into the squeezing opening formed by the wringer roller 100 and the side wall 202, the wiping material on the mop head comes into contact with the scraping part 102 of the wringer roller 100, generating friction and driving the wringer roller 100 to rotate. Simultaneously, due to the friction of the wiping material, the wringer roller 100 rolls along the movable track 500 towards the first end 501. When the wringer roller 100 rolls to the first end 501 of the movable track 500, it stops rolling. Furthermore, the anti-rotation structure 503 at the first end 501 of the movable track 500 contacts the end of the wringer roller 100, mechanically restraining it from rotating. At this point, the wringer roller 100 remains stationary, and the squeezing opening formed by its contact with the side wall 202 statically clamps, scrapes, and squeezes the wiping material, enhancing the scraping efficiency and effect of the wringer roller 100.

[0120] In one implementation, the anti-rotation structure 503 is a boss provided at the first end 501 of the movable track 500, and the two ends of the squeezing roller 100 have blocking parts; when the squeezing roller 100 rolls to the first end 501, the boss and the blocking parts cooperate to stop the squeezing roller 100 from rotating.

[0121] The first end 501 of the movable track 500 is provided with a boss that matches the end of the wringer 100. The end of the wringer 100 has a blocking part. When the wringer 100 rotates to the first end 501, the blocking part is inserted into the boss to form an interlock, driving the wringer 100 to stop rotating. The structure that achieves the anti-rotation function is simple, easy to manufacture, low in cost, and highly reliable. The squeezing opening formed by the stationary wringer and the side wall achieves static clamping, scraping, and squeezing of the wiping material, which can enhance the scraping efficiency and scraping effect of the wringer.

[0122] For example, the boss and the movable track can be integrally formed with the first sidewall or the second sidewall to ensure the stability and reliability of the overall structure. The boss structure can be a step, protrusion, or other structure formed at the first end 501 of the movable track 500 that can prevent the rotation of the squeezing roller 100. The two ends of the squeezing roller 100 can be the two ends of the rotating shaft 101 or the two ends of the mounting plate 103. No specific limitation is made in this embodiment.

[0123] like Figure 8 As shown, the two ends of the squeezing roller 100 have a cross-shaped structure. The two adjacent arms of the cross-shaped structure form a blocking part. When the squeezing roller 100 rolls to the first end 501, the boss engages between the two adjacent arms, stopping the squeezing roller 100 from rotating. By designing the two ends of the squeezing roller 100 as a cross-shaped structure and utilizing the blocking part formed by the adjacent arms to cooperate with the boss to form an anti-rotation structure, shape interlocking is achieved, resulting in a more precise and stable anti-rotation effect.

[0124] In another implementation, the anti-rotation structure 503 is a pawl located at the first end 501, and the two ends of the wringer 100 have ratchet structures. When the wringer 100 rolls to the first end 501 of the movable track 500, the pawl located at the first end 501 engages with the tooth grooves of the ratchet structures at both ends of the wringer 100, causing the wringer 100 to stop rotating. This anti-rotation function is simple in structure, easy to manufacture, low in cost, and highly reliable. The stationary wringer, in conjunction with the squeezing opening formed by the contact with the side wall, achieves static clamping, scraping, and squeezing of the object being wiped, enhancing the scraping efficiency and effect of the wringer.

[0125] In some embodiments, when the mop board moves forward, the wiping material of the mop board drives the wringer 100 to roll forward along the movable track 500 until the wringer 100 rolls forward to the first end 501 of the movable track 500, at which point the anti-rotation structure 503 provided at the first end 501 stops the wringer 100 from rotating forward. When the mop board moves in reverse, the wiping material of the mop board drives the wringer 100 to roll in reverse along the movable track 500 until the wringer 100 rolls in reverse to the second end 502 of the movable track 500, at which point the wiping material drives the wringer 100 to continue rotating in reverse at the second end 502.

[0126] The mop head moves forward and backward in the squeezing nozzle, driving the wringer roller 100 to roll forward and backward in the movable track 500. When the mop head moves forward, driving the wringer roller 100 to roll forward to the first end 501 of the movable track 500, the wringer roller 100 stops rolling. The anti-rotation structure 503 located at the first end 501 drives the wringer roller to stop rotating. Forward anti-rotation helps improve wiping efficiency and wiping effect. When the mop head moves backward, driving the wringer roller 100 to roll backward to the second end of the movable track 500, the wringer roller 100 stops rolling. The mop head drives the wringer roller 100 to continue rotating at the second end, so that the wringing mechanism achieves the functions of rolling squeezing and one-way anti-rotation.

[0127] In some embodiments, the movable tracks 500 on the two constrained sidewalls are inclined. When the mop board moves forward, the wiping material of the mop board drives the wringer 100 to roll along the movable track 500 in the direction of decreasing squeeze opening; when the mop board moves in the reverse direction, the wiping material of the mop board drives the wringer 100 to roll along the movable track 500 in the direction of increasing squeeze opening.

[0128] The inclined movable track 500 has a distance between the first end 501 and the side wall 202 that is less than the distance between the second end 502 and the side wall 202. This makes the squeezing opening smaller and smaller as the mop board moves forward, which helps to improve the scraping efficiency and scraping effect. As the mop board moves backward, the squeezing opening becomes larger and larger, making it easier for the mop board to easily detach from the squeezing opening.

[0129] It should be noted that the wringing mechanism 10 provided in this embodiment can be applied to self-wringing mops or mop buckets. When the mop is a self-wringing mop, the wringing mechanism 10 is mounted on the mop handle. In this case, forward movement of the mop plate means the mop plate moves upward relative to the wringing mechanism 10, and reverse movement of the mop plate means the mop plate moves downward relative to the wringing mechanism 10. The upper end of the movable track 500 is the first end 501, and the lower end is the second end 502. The movable track 500 is inclined, and the distance between the first end 501 and the side wall 202 is less than the distance between the second end 502 and the side wall 202. That is, during forward movement (upward movement) of the mop plate, the wringing opening becomes smaller, which helps improve the scraping efficiency and effect; during reverse movement (downward movement) of the mop plate, the wringing opening becomes larger, making it easier for the mop plate to easily detach from the wringing opening.

[0130] When the mop is used with the matching mop bucket for wiping, the squeezing mechanism 10 is located on the body of the mop bucket. Forward movement of the mop blade means it moves downwards relative to the squeezing mechanism 10, and reverse movement means it moves upwards relative to the squeezing mechanism 10. The lower end of the movable track 500 is the first end 501, and the upper end is the second end 502. The movable track 500 is tilted, and the distance between the first end 501 and the side wall 202 is less than the distance between the second end 502 and the side wall 202. That is, during forward movement (downward movement) of the mop blade, the squeezing opening becomes smaller, which helps improve wiping efficiency and effect; during reverse movement (upward movement) of the mop blade, the squeezing opening becomes larger, making it easier for the mop blade to easily detach from the squeezing opening.

[0131] This utility model also provides a self-squeezing mop, including: a squeezing mechanism 10, a mop plate, and a mop handle. The squeezing mechanism 10 is slidably connected to the mop handle, and the mop plate is rotatably connected to one end of the mop handle; the squeezing mechanism is the squeezing mechanism 10 provided in any of the above embodiments. The squeezing mechanism includes a base, a housing, and a squeezing roller. The base and housing are assembled to form the constraint sidewall of the squeezing mechanism. Both ends of the squeezing roller are disposed in movable tracks opened on the constraint sidewall. The squeezing roller moves within the movable tracks to clean and squeeze water from the wiping material on the mop plate. The rotating shaft and the scraping part of the squeezing roller are separately formed, simplifying the mold structure and reducing production difficulty, defect rate, and production costs. During assembly, the scraping part is detachably disposed on the outer periphery of the rotating shaft. When the scraping part wears due to long-term friction or the rotating shaft is bent and damaged, it is not necessary to replace the entire squeezing roller; only the scraping part or the rotating shaft needs to be replaced, making replacement and maintenance more convenient and reducing usage costs. Furthermore, the rotating shaft and the scraping section are circumferentially prevented from rotating after assembly, ensuring that the scraping section rotates synchronously with the rotating shaft and preventing slippage. This allows the scraping section to stably and evenly clean and wring water from the mop board, thus guaranteeing scraping efficiency and effectiveness. This solves the problems of complex mold design, high defect rate, and high production difficulty and cost associated with one-piece molded wringing rollers, as well as the problem of slippage and failure to rotate in the scraping section of split-molded wringing rollers, which affects scraping efficiency and effectiveness.

[0132] This utility model also provides a mop bucket, including: a bucket body and a squeezing mechanism 10 disposed at the opening of the bucket body. The squeezing mechanism 10 is the squeezing mechanism provided in any of the above embodiments. The squeezing mechanism includes a base, a housing, and a squeezing roller. The base and housing are assembled to form a constraint sidewall of the squeezing mechanism. Both ends of the squeezing roller are disposed in movable tracks opened on the constraint sidewall. The squeezing roller moves in the movable tracks to clean and squeeze water from the mop board. The rotating shaft and the scraping part of the squeezing roller are separately formed, which simplifies the mold structure, reduces production difficulty, reduces the defect rate, and reduces production costs. During assembly, the scraping part is detachably disposed on the outer periphery of the rotating shaft. When the scraping part wears due to long-term friction or the rotating shaft is bent and damaged, it is not necessary to replace the entire squeezing roller; only the scraping part or the rotating shaft needs to be replaced. Replacement and maintenance are more convenient, and the usage cost is reduced. Furthermore, the rotating shaft and the scraping section are circumferentially prevented from rotating after assembly, ensuring that the scraping section rotates synchronously with the rotating shaft and preventing slippage. This allows the scraping section to stably and evenly clean and wring water from the mop board, thus guaranteeing scraping efficiency and effectiveness. This solves the problems of complex mold design, high defect rate, and high production difficulty and cost associated with one-piece molded wringing rollers, as well as the problem of slippage and failure to rotate in the scraping section of split-molded wringing rollers, which affects scraping efficiency and effectiveness.
