Description

Technical Field

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

[0002] The wringing mechanism is essential for washing or wringing water from a mop, and generally consists of a main body and a scraper. In traditional wringing mechanisms, the main body and scraper are manufactured as a single piece, resulting in a single-function scraper that fails to meet diverse user needs. To provide multi-functional scrapers, existing technologies determine the scraper's structure and movement based on product positioning, and then determine the wringing mechanism's structure accordingly. The main body and scraper are manufactured separately, and then assembled to form the overall wringing mechanism structure. In existing technologies, the main body can be either one-piece or separate. For a one-piece main body, a guide structure for installing the scraper is required on the inner wall, increasing manufacturing difficulty and reducing structural stability, potentially causing the scraper to detach from the wringing mechanism during movement. For a separate main body, assembly requires squeezing the main body, increasing manufacturing costs and involving more assembly steps. Furthermore, excessive deformation of the main body during scraper installation can lead to structural instability during wringing mechanism operation. Utility Model Content

[0003] This utility model provides a wringing mechanism, a mop, and a mop bucket, which at least solves the problems of difficult manufacturing of the main body and easy loosening or detachment of the scraping parts when the main body structure is integrated, as well as the problem of structural instability of the wringing mechanism when the main body structure is split due to the squeezing of the main body during the installation of the scraping parts.

[0004] In a first aspect, this utility model provides a water-squeezing mechanism, comprising:

[0005] The main body is provided with an extrusion channel, the extrusion channel having abutting sidewalls and setting sidewalls disposed opposite to each other, and a constraint sidewall located between the abutting sidewalls and the setting sidewalls;

[0006] A scraping component, wherein the end of the scraping component has a mounting portion;

[0007] The constraint sidewall is provided with a mounting hole, the mounting hole having a working area near the sidewall and a mounting area communicating with the working area. The scraping member is inserted into the extrusion channel from the mounting area and moves towards the working area until the mounting part is engaged with the working area.

[0008] A limiting block is inserted into the mounting area and limits the mounting part, so that the scraping member is disposed on the side of the extrusion channel near the mounting side wall and forms an extrusion port for inserting the mop board between the extrusion channel and the abutting side wall. The scraping member is used to scrape and / or extrude the wiping material of the mop board when the mop board moves in the extrusion port.

[0009] In some embodiments, the extrusion channel includes two opposing constraint sidewalls, each of which is provided with the mounting hole;

[0010] The scraper is inserted into the extrusion channel through the mounting area of ​​the mounting hole on one constraint sidewall until the mounting part at one end of the scraper is inserted into the mounting area of ​​the other constraint sidewall, and moves toward the working area until the mounting parts at both ends of the scraper are respectively engaged with the working areas of the two constraint sidewalls.

[0011] The water-squeezing mechanism includes two limiting blocks, which are respectively inserted into the mounting areas of the two constraint sidewalls and limit the mounting portions at both ends of the scraping component.

[0012] In some embodiments, the abutting sidewall, the setting sidewall, and the two constraining sidewalls enclose the extrusion channel.

[0013] In some embodiments, the main body is a single piece.

[0014] In some embodiments, the limiting block has a first portion whose shape is adapted to the connecting area between the working area and the mounting area; when the limiting block is inserted into the mounting area, the first portion blocks the connecting area between the working area and the mounting area, so as to restrict the mounting portion to the working area;

[0015] And / or, the limiting block has a second portion whose shape is adapted to the mounting area; when the limiting block is inserted into the mounting area, the second portion blocks the entire mounting area to restrict the mounting part from detaching from the working area.

[0016] In some embodiments, the top surface of the limiting block near the extrusion channel is recessed to form a weight-reducing groove.

[0017] In some embodiments, a support rib is provided between the opposite sides of the weight-reducing groove.

[0018] In some embodiments, when the mounting portion is formed on the end faces of both ends of the scraper and the mounting portion is confined to the working area, the side of the constraint sidewall near the extrusion channel limits the end face of the scraper to restrict the scraper from disengaging from the working area along the direction of insertion into the extrusion channel.

[0019] In some embodiments, the mounting portion is a convex shaft formed on the end faces of both ends of the scraper.

[0020] In some embodiments, the cam shaft has an anti-rotation structure, and when the cam shaft is limited to the working area, it abuts against the side wall of the working area to limit the rotation of the scraping component when the mop plate moves in the squeezing port.

[0021] In some embodiments, the limiting block is inserted into the installation area and blocks the communication area between the working area and the installation area, such that the side wall of the working area and the limiting block form an inclined groove. When the mop plate moves in the squeezing port, it drives the mounting part of the scraping member to slide in the inclined groove to change the distance between the scraping member and the abutting side wall.

[0022] In some embodiments, the mounting portion is a convex shaft formed on the end faces of both ends of the scraper, the convex shaft having two opposing limiting sidewalls, the two limiting sidewalls respectively abutting against two opposing sidewalls extending along the length direction of the inclined groove, so as to restrict the mop plate from driving the scraper to rotate when it moves in the squeezing port.

[0023] In some embodiments, the sidewall of the mounting device is provided with an inclined support plate, and the side of the scraper near the sidewall of the mounting device is provided with an inclined limiting groove. When the scraper moves from the mounting area into the extrusion channel towards the working area, the inclined support plate is inserted into the inclined limiting groove, and when the mounting part of the scraper slides in the inclined groove, the inclined support plate slides along the inclined limiting groove.

[0024] In some embodiments, the dewatering mechanism further includes a cover plate, and the limiting block is disposed on the cover plate. When the cover plate covers the outside of the constraint sidewall, the limiting block is inserted into the mounting area and limits the mounting portion.

[0025] In some embodiments, the cover plate has a fixing part, and the constraint sidewall is provided with a mating part;

[0026] When the cover plate is placed on the outside of the constraint sidewall, the fixing part cooperates with the mating part, so that the cover plate is fixed on the outside of the constraint sidewall.

[0027] In some embodiments, the fixing part is a snap-fit ​​post formed on the side of the cover plate near the constraint sidewall, and the mating part is a mating hole or a mating groove;

[0028] When the cover plate is placed on the outside of the constraint sidewall, the snap-fit ​​post is inserted into the mating hole or the mating groove and snaps into the mating hole or the mating groove.

[0029] In some embodiments, when the snap-fit ​​post is inserted into the mating hole, the snap-fit ​​post has two opposing spring arms, a clearance groove between the two spring arms, and a limiting platform at the ends of the two spring arms.

[0030] The snap-fit ​​pin is inserted into the mating hole until the ends of the two spring arms pass through the mating hole and snap into the side of the constraint sidewall near the extrusion channel.

[0031] In some embodiments, the shape of the mounting area is adapted to the cross-sectional shape of the scraper.

[0032] In some embodiments, a guide wheel is provided on the side wall against which the mop is abutting. When the scraping member is disposed on the side of the squeezing channel near the side wall, a squeezing opening is formed between the member and the guide wheel for the mop board to be inserted. When the mop board moves in the squeezing opening, the guide wheel abuts against the top surface of the mop board where no wiping material is disposed, and rotates under the influence of the top surface.

[0033] In some embodiments, the recessed sidewall is provided with a mounting groove, and the two opposite sidewalls of the mounting groove are provided with shaft holes. The side of the shaft hole near the extrusion channel is open. The guide wheel is provided with a rotating shaft on both sides. The rotating shaft enters the shaft hole through the opening and is rotatably connected to the shaft hole. The size of the opening is smaller than the diameter of the rotating shaft to restrict the rotating shaft from coming out of the shaft hole.

[0034] In some embodiments, the opening of the shaft hole near the constraint sidewall extends to the constraint sidewall and forms a through hole on the constraint sidewall.

[0035] In some embodiments, the body is provided with another extrusion channel, and the abutting sidewalls of the two extrusion channels are arranged adjacent to each other;

[0036] The constraint sidewall of the other extrusion channel is provided with a through hole, through which the extrusion roller is inserted into the other extrusion channel. The cover plate of the dewatering mechanism is placed on the outside of the constraint sidewall of the other extrusion channel and abuts against the end of the extrusion roller to restrict the extrusion roller from dislodging from the direction of insertion into the other extrusion channel.

[0037] In some embodiments, the extrusion opening formed between the extrusion roller and the opposing abutment sidewall and the extrusion opening formed between the scraper and the opposing abutment sidewall are of different sizes.

[0038] Secondly, this utility model provides a mop, comprising:

[0039] Wringing device, mop board, and mop handle;

[0040] The wringing device is slidably connected to the mop handle, and the mop plate is rotatably connected to one end of the mop handle;

[0041] The squeezing device is provided with the squeezing mechanism described in any embodiment of the first aspect at one end near the mop board.

[0042] Thirdly, this utility model provides a mop bucket, comprising:

[0043] 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 provided in any embodiment of the first aspect.

[0044] The water-squeezing mechanism provided in this embodiment has mounting holes on the constraint sidewall of the extrusion channel, which are divided into an installation area and a working area. When installing the scraper, the scraper can be inserted into the extrusion channel from the installation area and moved until the installation part of the scraper moves to the working area of ​​the mounting hole. Then, a limiting block is inserted into the installation area to limit the installation part of the scraper. The above installation method is not limited to whether the main body is integrated or split. For an integrated main body, the above installation method does not require a guide structure for installing the scraper on the inner wall of the extrusion channel, which reduces the manufacturing difficulty of the main body and can prevent the scraper from easily detaching from the water-squeezing mechanism during movement. For a split main body, it is not necessary to extrude the main body to deform it in order to install the scraper, thereby avoiding the situation where the water-squeezing mechanism is unstable during use due to excessive deformation of the main body when installing the scraper.

[0067] 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.

[0068] The following is for reference. Figures 1 to 10 The following describes embodiments of the present invention.

[0069] According to an embodiment of the present invention, a squeezing mechanism is provided, comprising: a main body 1, a scraping member 2, and a limiting block 31. The main body 1 is provided with a squeezing channel, which has an abutting sidewall 11 and a setting sidewall 12 disposed opposite to each other, and a constraint sidewall 13 located between the abutting sidewall 11 and the setting sidewall 12. The scraping member 2 has a mounting portion 21 at its end. The constraint sidewall 13 is provided with a mounting hole 131, which has a working area 1311 near the setting sidewall 12 and a mounting area 1312 communicating with the working area 1311. The scraping member 2 is inserted into the squeezing channel from the mounting area 1312 and moves towards the working area 1311 until the mounting portion 21 engages with the working area 1311. The limiting block 31 is inserted into the installation area 1312 and limits the installation part 21, so that the scraping member 2 is set on the side of the extrusion channel near the side wall 12 and forms an extrusion port for the mop board 20 to be inserted between it and the side wall 11. The scraping member 2 is used to scrape and / or squeeze the wiping material of the mop board 20 when the mop board 20 moves in the extrusion port.

[0070] The water-squeezing mechanism provided in this embodiment has a mounting hole 131 on the constraint side wall 13 of the main body of the water-squeezing mechanism. The mounting hole 131 includes a mounting area 1312 and a working area 1311. When installing the scraping component 2, the scraping component 2 can be inserted into the squeezing channel from the mounting area 1312 and moved until the mounting part 21 of the scraping component 2 moves to the working area 1311 of the mounting hole 131. Then, the mounting part 21 of the scraping component 2 is limited by the limiting block 31 to prevent the mounting part 21 from falling back to the mounting area 1312 when the scraping component 21 is scraping and / or squeezing, which would cause the scraping component 2 to loosen or fall off.

[0071] The above installation method is not limited by whether the main body 1 is one-piece or split. For a one-piece main body, the above installation method does not require a guide structure from the edge to the working area on the inner wall of the extrusion channel to install the scraper 2, ensuring the structural stability of the main body 1 and reducing the manufacturing difficulty of the main body 1. For a split main body 1, it is not necessary to extrude the main body 1 to deform it in order to install the scraper 2, thus avoiding the instability of the squeezing mechanism caused by excessive deformation of the main body 1 when installing the scraper 2. Since the main body structure is not restricted by the structure or installation method of the scraper, the structure of the main body can be adjusted according to other needs. For example, if it is necessary to reduce costs or assembly steps, the main body can be made into one piece, that is, the side walls forming the extrusion channel can be integrally molded; if it is necessary to assemble with other parts of the mop or mop handle, the main body can also be made into multiple assemblable parts.

[0072] Furthermore, in this embodiment, the scraping component 2 is installed using mounting holes, which will not cause deformation of the main body 1 of the squeezing mechanism. Therefore, when scraping and / or squeezing the wiping material, the squeezing mechanism structure is stable, which can ensure a stable squeezing effect.

[0073] It is understood that in this embodiment, the wiping material of the mop board 20 can be a mop cloth, non-woven fabric, sponge pad, or other washable pad disposed on the bottom surface of the mop board 20. The scraping component 2 mainly scrapes and / or squeezes the wiping material on the mop board 20 to clean the wiping material and / or dehydrate it. The scraping component 2 can be a squeegee, a squeezing roller, a comb, or other structures capable of scraping and / or squeezing the wiping material; no specific limitation is made in this embodiment.

[0074] In some embodiments, such as Figure 2 and Figure 3 As shown, the extrusion channel includes two opposing constraint sidewalls 13, each with a mounting hole 131. The scraper 2 is inserted into the extrusion channel through the mounting area 1312 of the mounting hole 131 in one constraint sidewall 13 until the mounting portion 21 at one end of the scraper 2 is inserted into the mounting area 1312 of the other constraint sidewall 13, and moves towards the working area 1311 until the mounting portions 21 at both ends of the scraper 2 are respectively engaged with the working areas 1311 of the two constraint sidewalls 13. The squeezing mechanism 101 includes two limiting blocks 31, which are respectively inserted into the mounting areas 1312 of the two constraint sidewalls 13 and limit the mounting portions 21 at both ends of the scraper 2. By setting two constraint sidewalls 13 with symmetrical mounting holes 131 on them, the scraper 2 is further facilitated in installation. Two limiting members 31 are inserted into the mounting area 1312 and limit the mounting portions 21 at both ends of the scraper 2, preventing it from falling back into the mounting area 1312 during use, thus further enhancing the stability of the scraper 2. Furthermore, the symmetrically arranged mounting holes 131 ensure uniform force distribution on both ends of the scraper 2 and the constraint sidewalls 13 during scraping and / or squeezing, ensuring the stability of the water-squeezing mechanism and thus ensuring a uniform and stable water-squeezing effect.

[0075] In some embodiments, such as Figures 1 to 3 As shown, the extrusion channel is formed by the side wall 11, the side wall 12, and the two constraint side walls 13, which makes the extrusion channel structure stable and can prevent the extrusion channel from deforming during use, thereby preventing the scraping part 2 from loosening or falling off during use.

[0076] In some embodiments, such as Figures 1 to 9As shown, the main body 1 is a single piece. The one-piece molding of the main body 1 not only improves the overall structural strength of the squeezing mechanism and prevents deformation of the main body 1 during use, which could cause the scraping part 2 to loosen or fall off, but also simplifies the manufacturing process of the squeezing mechanism, reduces production costs, and improves assembly efficiency.

[0077] In related technologies, if the main body 1 is a single piece, a guide structure needs to be provided inside the squeezing channel when installing the scraping component 2. For example, a guide groove can be inclinedly provided on the constraint sidewall 13 (the inclination direction can be from the upper edge of the constraint sidewall 13 near the abutting sidewall 11 towards the working area 1311). When the scraping component 2 is squeezed, the mounting part 21 can slide along the guide groove from the edge of the constraint sidewall 13 towards the working area 1311. At the same time, the mounting part 21 squeezes the two constraint sidewalls 13 outward to make them move away from each other until the mounting part 21 crosses the guide groove and inserts into the working area 1311. Due to the presence of the guide groove, the stability of the constraint sidewall 13 and the working area 1311 is poor, resulting in a defect of poor structural stability in the main body of the single piece in related technologies. Moreover, when the pressure of the wiping material squeezing the scraping component 2 is large, the scraping component 2 may easily detach from the squeezing mechanism.

[0078] In the embodiment disclosed in this utility model, a mounting hole 131 is provided on the constraint sidewall 13. The mounting hole 131 includes a mounting area 1312 and a working area 1311. When installing the scraper 2, the scraper 2 is inserted into the extrusion channel from the mounting area 1312 and moved until the mounting part 21 of the scraper 2 moves to the working area 1311 of the mounting hole 131. Then, the limiting block 31 is inserted into the mounting area 1312 to limit the mounting part 21 of the scraper 2. It is not necessary to set a guide structure inside the extrusion channel, and the distance between the two constraint sidewalls will not be increased during the installation of the scraper 2, ensuring the stability of the constraint sidewall 13 and the working area 1311, thereby ensuring the stability of the main structure, and further ensuring that the scraper 2 can work stably during scraping and / or extrusion, and preventing the scraper 2 from detaching from the squeezing mechanism. Furthermore, in comparison, the manufacturing difficulty of setting the inclined guide groove in the related technology is greater than the manufacturing difficulty of setting the mounting hole 131 in this embodiment. Using the mounting hole 131 to install the scraping part 2 can reduce the manufacturing cost of the main body.

[0079] Meanwhile, the one-piece molding of the main body 1 can greatly reduce the production cost of the dewatering mechanism, requiring only one set of molds to manufacture the main body 1. The one-piece molding of the main body 1 also reduces installation difficulty, improves assembly efficiency, and facilitates large-scale production and assembly.

[0080] In some embodiments, such as Figures 2 to 4As shown, the limiting block 31 has a first portion 311 whose shape is adapted to the connecting area of ​​the working area 1311 and the mounting area 1312; when the limiting block 31 is inserted into the mounting area 1312, the first portion 311 blocks the connecting area between the working area 1311 and the mounting area 1312, so as to restrict the mounting part 21 to the working area 1311.

[0081] In one example, such as Figures 2 to 4 As shown, the working area 1311 and the installation area 1312 can be directly connected, that is, the connected area of ​​the working area 1311 and the installation area 1312 is the overlapping area of ​​the working area 1311 and the installation area 1312. The first part 311 can be Figure 4 The limiting plate shown is inserted into the overlapping area of ​​the working area 1311 and the installation area 1312 to form the edge of the working area 1311. This restricts the installation part 21 to move within the area enclosed by the working area 1311 and the limiting plate, preventing it from crossing the limiting plate and entering the installation area 1312, thereby ensuring that the scraping part 2 can work stably during use.

[0082] In another example, the working area 1311 and the installation area 1312 can also be connected by a channel. Therefore, the connected area is the aforementioned channel. The first part 311 can be a stop block set in the channel. The stop block is inserted into the channel between the working area 1311 and the installation area 1312, so that the installation part 21 is restricted to the range enclosed by the working area 1311 and the side wall of the stop block near the working area 1311, and will not cross the stop block and enter the installation area 1312, thereby ensuring that the scraping part 2 can work stably during use.

[0083] In practical applications, the first part 311 can also be other structures that can achieve the effect of blocking connected areas, but this embodiment does not make specific limitations.

[0084] In some embodiments, such as Figures 2 to 4 As shown, the limiting block 31 has a second part whose shape is adapted to the mounting area 1312; when the limiting block 31 is inserted into the mounting area 1312, the second part blocks the entire mounting area 1312 to restrict the mounting part 21 from detaching from the working area 1311.

[0085] In one example, the second part of the limiting block 31 can be a structure that is adapted to the overall size and shape of the installation area 1312. By precisely fitting the second part, the entire area of ​​the installation area 1312 is sealed off, and the entire installation area 1312 is completely filled by the second part, which improves the structural stability of the limiting block and prevents the scraping component 2 from falling out of the squeezing mechanism due to insufficient support provided by the limiting block, thus ensuring the working stability of the scraping component 2. Moreover, the structure of the second part of the limiting block 31 that is adapted to the overall size and shape of the installation area 1312 can prevent abnormal noise.

[0086] In another example, the second part of the limiting block 31 can be a structure that adapts to the shape of the installation area 1312. For example, the second part is a quadrilateral block. The upper and lower sides or the left and right sides of the quadrilateral block are adapted to the shape of the installation area 1312, which improves the structural stability of the limiting block to a certain extent and prevents the scraping component 2 from falling out of the squeezing mechanism due to insufficient support provided by the limiting block, thus ensuring that the scraping component 2 can work stably during use.

[0087] In practical applications, the second part can also be other structures that can achieve the effect of sealing the installation area 1312, but this embodiment does not make specific limitations.

[0088] In some embodiments, such as Figures 1 to 6 As shown, the limiting block 31 has a first part 311 and a second part. The shape of the first part 311 is adapted to the connecting area between the working area 1311 and the mounting area 1312, and the shape of the second part is adapted to the mounting area 1312. When the limiting block 31 is inserted into the mounting area 1312, the first part 311 blocks the connecting area between the working area 1311 and the mounting area 1312, and the second part blocks the entire mounting area 1312, so as to restrict the mounting part 21 within the working area 1311 and prevent the mounting part 21 from detaching from the working area 1311. By blocking the connecting area with the first part 311 and blocking the mounting area 1312 with the second part, the double blocking further enhances the structural stability of the limiting block and further prevents the scraping part 2 from detaching from the squeezing mechanism due to insufficient support provided by the limiting block, thereby ensuring the working stability of the scraping part 2.

[0089] In some embodiments, such as Figure 4 As shown, the top surface of the limiting block 31 near the extrusion channel is recessed to form a weight reduction groove 312, which reduces the weight of the limiting block 31, thereby reducing the overall weight of the dewatering mechanism, reducing the material used to manufacture the limiting block 31, and lowering manufacturing and transportation costs.

[0090] In some embodiments, the limiting block 31 may also be a groove recessed into the compression channel on the constraint sidewall 13, or it may be a hollow structure, which can reduce the weight of the limiting block 31 while restricting the mounting part 21 in the working area 1311.

[0091] In some embodiments, such as Figure 4 As shown, support ribs 313 are provided between the opposite sides of the weight reduction groove 312, which improves the structural strength of the limiting block 31. For example, the support ribs 313 can be provided on both sides that exert resistance on the mounting part 21, such as the left and right sides. While improving the structural strength of the limiting block 31, they can also provide support for the scraping member 2, further confining the scraping member 2 within the working area 1311. This prevents the scraping member 2 from detaching from the squeezing mechanism due to insufficient support provided by the limiting block 31, thus ensuring the working stability of the scraping member 2.

[0092] In some embodiments, such as Figure 2 , Figure 5 As shown, the mounting portion 21 is formed on the end faces of both ends of the scraper 2. When the mounting portion 21 is confined to the working area 1311, the side of the constraint sidewall 13 near the extrusion channel limits the end face of the scraper 2, thereby preventing the scraper 2 from detaching from the working area 1311 along the direction of insertion into the extrusion channel. The constraint sidewall 13 limits the end face of the scraper 2 in the longitudinal direction. The constraint sidewall 13 and the limiting block 31 provide multi-directional limiting, further improving the working stability of the scraper 2 and preventing the scraper 2 from detaching from the squeezing mechanism from the direction of the constraint sidewall during scraping and / or extrusion.

[0093] In some embodiments, such as Figure 2 , Figure 5 As shown, the mounting portion 21 is a convex shaft formed on the end faces of both ends of the scraper 2. The convex shaft and the scraper portion 21 of the scraper 2 form an integral structure, which improves the overall structural strength of the scraper 2, simplifies the manufacturing process of the scraper 2, reduces manufacturing costs, and further simplifies the installation steps.

[0094] For example, the length of the convex shaft in the longitudinal direction of the scraper 2 can be equal to or similar to the thickness of the constraint sidewall 13, and the length of the scraper part of the scraper 2, except for the convex shafts at both ends, can be equal to or similar to the distance between the two constraint sidewalls 13, which further improves the working stability of the scraper 2 and avoids the scraper 2 from falling out of the squeezing mechanism due to the short length of the scraper part or the convex shaft.

[0095] In some embodiments, the cam shaft has an anti-rotation structure. When the cam shaft is limited to the working area 1311, it abuts against the side wall of the working area 1311 to limit the rotation of the scraping member 2 when the mop plate 20 moves in the squeezing port. The anti-rotation structure prevents the scraping member 2 from rotating under the drive of the wiping material during scraping and / or squeezing. The scraping part of the scraping member 2 always faces the wiping material, ensuring uniform squeezing and keeping the scraping and / or squeezing effect of the wiping material stable.

[0096] In related technologies, if a scraper 2 is to be installed to prevent rotation relative to the main body 1, an installation opening with a shape matching the cross-sectional shape of the scraper 2 can be provided on the constraint sidewall 13. Furthermore, the shape of the installation part of the scraper 2 must match the cross-sectional shape of the scraper 2, making installation inconvenient and prone to detaching from the squeezing mechanism during use. Alternatively, the main body 1 can be designed as a split type, with the scraper 2 installed on one part before assembling the other parts to form a single main body. The opposing notches of the two parts form the anti-rotation structure after assembly. This anti-rotation method results in higher manufacturing costs for the main body and more assembly steps for the squeezing mechanism.

[0097] In the embodiment disclosed in this utility model, the mounting part 21 is a convex shaft formed on the end faces of both ends of the scraper 2. When installing the scraper 2, it is inserted into the mounting area 1312 of the mounting hole 131 and moved to the working area 1311. The limiting block 31 is inserted into the mounting area 1312 to limit the convex shaft of the scraper 2. The anti-rotation structure on the convex shaft prevents the scraper 2 from rotating. The scraper is easy to install and will not rotate during use. Moreover, the cross-section of the convex shaft is smaller than the cross-section of the scraper 2. During use, the constraint sidewall 13 limits the end face of the scraper 2, and the limiting block 31 limits the side of the convex shaft facing the mounting area 1312, so that the scraper 2 works stably and avoids it from coming off the squeezing mechanism during use.

[0098] Compared to using a split main body for anti-rotation, the anti-rotation structure on the cam shaft in this embodiment does not affect the installation method of the scraper 2. That is, the scraper 2 is still inserted into the extrusion channel from the installation area 1312 and moved until the cam shaft of the scraper 2 moves to the working area 1311 of the installation hole 131. Then, the limiting block 31 is inserted into the installation area 1312 to limit the installation part 21 of the scraper 2. The anti-rotation structure on the cam shaft prevents the scraper 2 from rotating. Under the premise of achieving the same anti-rotation effect, this installation method can reduce the manufacturing cost of the main body, reduce the installation difficulty, improve the assembly efficiency, and is conducive to large-scale production and assembly. Moreover, it does not require extruding the main body 1 to deform the main body 1 to install the scraper 2, thereby avoiding the situation where the water squeezing mechanism is unstable when using due to excessive deformation of the main body 1 when installing the scraper 2.

[0099] For example, the anti-rotation structure can be a protrusion or baffle on the cam shaft, or it can be a groove that engages with the protrusion on the side wall of the working area 1311. In practical applications, it can also be other structures that can achieve the anti-rotation effect, but this embodiment does not make specific limitations.

[0100] In some embodiments, such as Figures 2 to 7 As shown, the limiting block 31 is inserted into the installation area 1312 and blocks the communication area between the working area 1311 and the installation area 1312, so that the side wall of the working area 1311 and the limiting block 31 form an inclined groove. When the mop plate 20 moves in the squeezing port, it drives the mounting part 21 of the scraping component 2 to slide in the inclined groove to change the distance between the scraping component 2 and the side wall 11. The mounting part 21 is set in the inclined groove. When the mop plate 20 moves upward relative to the wringing mechanism, the wiping material of the mop plate 20 drives the mounting part 21 of the scraping component 2 to slide upward in the inclined groove and gradually approach the wiping material, thereby improving the scraping and / or wringing effect and increasing the wringing efficiency.

[0101] In related technologies, if an inclined scraper 2 is to be installed, an inclined groove adapted to the cross-sectional shape of the scraper 2 can be set. However, the shape of the mounting part of the scraper 2 needs to be consistent with the cross-sectional shape of the scraper 2, which makes the scraper difficult to install and prone to detaching from the squeezing mechanism during use. Alternatively, the main body 1 can be set as a split type, with the scraper 2 installed on one part and the other parts assembled to form a whole main body. The inclined groove is formed after the opposing notches of the two parts are assembled. This method of setting the inclined groove results in a higher manufacturing cost for the main body and more assembly steps for the squeezing mechanism.

[0102] In the embodiment disclosed in this utility model, the limiting block 31 is inserted into the installation area 1312 and blocks the communication area between the working area 1311 and the installation area 1312, so that the side wall of the working area 1311 and the limiting block 31 form an inclined groove. The installation part 21 slides in the inclined groove. With this inclined groove setting, the installation method of the scraper 2 is as described above, which is convenient for installation. Moreover, under the double-sided limiting of the limiting block 31 and the constraining side wall 13, the scraper 2 works stably and avoids falling out of the squeezing mechanism during use.

[0103] Compared to a split-type main body with an inclined groove, this embodiment uses the side wall of the working area 1311 and the limiting block 31 to form an inclined groove. While achieving the same effect of the mounting part 21 sliding in the inclined groove to improve the squeezing effect, this inclined groove setting method can reduce the manufacturing cost of the main body, reduce the installation difficulty, improve the assembly efficiency, and facilitate large-scale production and assembly. Furthermore, it does not require squeezing the main body 1 to deform it in order to install the scraper 2, thereby avoiding the instability of the squeezing mechanism caused by excessive deformation of the main body 1 when installing the scraper 2.

[0104] In some embodiments, such as Figures 2 to 7 As shown, the mounting part 21 is a convex shaft formed on the end faces of both ends of the scraper 2. The convex shaft has two opposing limiting sidewalls, which abut against two opposing sidewalls extending along the length direction of the inclined groove, respectively, to restrict the mop plate 20 from rotating the scraper 2 when it moves in the squeezing orifice. Figure 2 , Figure 5 , Figure 7 As shown, the limiting sidewall of the cam shaft can be the long sidewall of the mounting part 21. The limiting sidewall abuts against the sidewall of the inclined groove, so that the limiting sidewall is precisely fitted into the sidewall of the inclined groove, ensuring that the scraping part 2 will not rotate during scraping and / or extrusion, thereby ensuring a uniform and stable extrusion effect. Moreover, the two limiting sidewalls of the cam shaft abut against the two opposite sidewalls of the inclined groove that extend along the length direction, so that the limiting block 31 and the sidewall of the inclined groove opposite to the limiting block 31 limit the cam shaft, ensuring the stability of the scraping part 2 and avoiding the situation where the cam shaft rotates in the inclined groove due to insufficient pressure caused by the large sidewall of the inclined groove.

[0105] In some embodiments, such as Figure 5 and Figure 6 As shown, the side wall 12 is provided with an inclined support plate 121, and the scraper 2 is provided with an inclined limiting groove 22 on the side near the side wall 12. When the scraper 2 moves from the installation area 1312 into the extrusion channel towards the working area 1311, the inclined support plate 121 inserts into the inclined limiting groove 22, and the inclined support plate 121 slides along the inclined limiting groove 22 when the installation part 21 of the scraper 2 slides in the inclined groove. By providing an inclined limiting groove 22 on the back of the scraper 2 facing away from the object to be wiped, and providing an inclined support plate 121 inserted into the inclined limiting groove 22 on the side wall 12, the scraper 2 has a supporting force in the length direction, avoiding deformation of the scraper 2 due to the extrusion of the object to be wiped. This not only ensures a uniform and stable extrusion effect, but also extends the service life of the scraper 2.

[0106] In some embodiments, such as Figures 1 to 8 As shown, the squeezing mechanism also includes a cover plate 3, and a limiting block 31 is disposed on the cover plate 3. When the cover plate 3 is placed on the outside of the constraint sidewall 13, the limiting block 31 is inserted into the mounting area 1312 and limits the mounting part 21. By covering the outside of the constraint sidewall 13 with the cover plate 3, the end face of the mounting part 21 of the scraping component 2 is limited, further stabilizing the operation of the scraping component 2 and preventing the scraping component 2 from detaching from the working area 1311 from the direction of the constraint sidewall 13 during scraping and / or squeezing.

[0107] In some embodiments, such as Figures 1 to 8 As shown, the cover plate 3 has a fixing part 32, and the constraint sidewall 13 is provided with a mating part 132. When the cover plate 3 is placed on the outside of the constraint sidewall 13, the fixing part 32 and the mating part 132 cooperate to fix the cover plate 3 on the outside of the constraint sidewall 13. Through the cooperation design of the fixing part 32 and the mating part 132, the cover plate 3 can be firmly fixed on the constraint sidewall 13, further stabilizing the operation of the scraping component 3 and preventing the cover plate 3 from falling off and causing the scraping component 2 to detach from the squeezing structure.

[0108] In some embodiments, such as Figure 3 and Figure 4 As shown, the fixing part 32 is a snap-fit ​​post formed on the side of the cover plate 3 near the constraint sidewall 13, and the mating part 132 is a mating hole or a mating groove. When the cover plate 3 is placed on the outside of the constraint sidewall 13, the snap-fit ​​post is inserted into the mating hole or the mating groove and snaps into the mating hole or the mating groove. The snap-fit ​​method of the snap-fit ​​post and the mating hole or the mating groove makes it easy to install the cover plate 3 on the constraint sidewall 13, simplifying the installation steps. Moreover, the snap-fit ​​method is detachable, making it easy to remove the cover plate 3 from the constraint sidewall 13 to replace the scraping part 2.

[0109] In some embodiments, such as Figure 3 , Figure 4 and Figure 8As shown, when the snap-fit ​​post is inserted into the mating hole, the snap-fit ​​post has two opposing elastic arms 321, with a clearance groove 322 between the two elastic arms 321, and a limiting platform 323 at the ends of the two elastic arms 321; the snap-fit ​​post is inserted into the mating hole until the ends of the two elastic arms 321 pass through the mating hole and snap onto the side of the constraint sidewall 13 near the extrusion channel. In this embodiment, when installing the cover plate 3, under the extrusion around the mating hole, the two elastic arms 321 move closer to the center, making it easier to install the cover plate 3 onto the constraint sidewall 13. The limiting platform 323 abuts against the inner side of the constraint sidewall 13, preventing the cover plate 3 from falling off, further ensuring that the cover plate 3 is firmly snapped onto the constraint sidewall 13, thereby further ensuring the stable operation of the scraping component 2.

[0110] In some embodiments, such as Figures 2 to 7 As shown, the shape of the installation area 1312 is adapted to the cross-sectional shape of the scraper 2. By setting an installation area that fits the shape of the scraper 2, the stability of the constraint sidewall 13 is maximized while ensuring smooth installation. This avoids the situation where the constraint sidewall 13 is not strong enough due to the large size of the installation area 1312, which could lead to structural instability and cause the scraper 2 to come off the squeezing mechanism. Furthermore, if the limit block 31 falls off, the installation area 1312 with the adapted shape can play a certain role in limiting the scraper 2 in the initial stage of the limit block 31 falling off.

[0111] In some embodiments, such as Figures 2 to 9 As shown, a guide wheel is provided against the side wall 11. When the scraping component 2 is positioned on the side of the squeezing channel near the side wall 12, it forms a squeezing opening between itself and the guide wheel for the mop board 20 to be inserted. When the mop board 20 moves in the squeezing opening, the guide wheel abuts against the top surface of the mop board 20 where no wiping material is placed, and rotates under the influence of the top surface. By providing the guide wheel, when the mop board 20 moves up and down in the squeezing opening, the top surface of the mop board 20 abuts against the guide wheel and drives the guide wheel to rotate back and forth, which can reduce the friction when the mop board 20 moves, achieving a labor-saving effect. Furthermore, the guide wheel applies a pushing force towards the scraping component 2 to the top surface of the mop board 20, further improving the scraping and / or squeezing effect and increasing the squeezing efficiency.

[0112] In some embodiments, such as Figures 2 to 9As shown, a mounting groove 111 is recessed against the side wall 11. Shaft holes 112 are provided on the two opposite side walls of the mounting groove 111, with the side of the shaft hole 112 near the extrusion channel being open. Rotating shafts are provided on both sides of the guide wheel. The rotating shafts enter the shaft holes 112 through the openings and are rotatably connected to the shaft holes 112. The size of the opening is smaller than the diameter of the rotating shaft to prevent it from dislodging from the shaft hole 112. The diameter of the guide wheel's rotating shaft is slightly larger than the height of the opening, facilitating the pushing of the rotating shaft into the shaft hole 112 along the opening to complete the installation of the guide wheel. During use, because the diameter of the rotating shaft is larger than the height of the opening, the rotating shaft can rotate stably within the shaft hole 112 and will not dislodge from it.

[0113] In some embodiments, such as Figures 1 to 7 As shown, the opening of the shaft hole 112 near the constraint sidewall 13 extends into the constraint sidewall 13, forming a through hole 113 on the constraint sidewall 13. The design of the through hole 113 facilitates the installation and removal of the guide wheel, and also facilitates the removal of the main body from the mold during production.

[0114] In some embodiments, such as Figures 1 to 9 As shown, the main body 1 is provided with another extrusion channel 14, and the abutting sidewalls 11 of the two extrusion channels are arranged adjacent to each other; the constraint sidewall 13 of the other extrusion channel 14 is provided with a through hole 133, and the extrusion roller 4 is inserted into the other extrusion channel 14 through the through hole 133. The cover plate 3 is covered on the outside of the constraint sidewall 13 of the other extrusion channel 14 and abuts against the end of the extrusion roller 4 to restrict the extrusion roller 4 from coming out from the direction of insertion into the other extrusion channel 14.

[0115] For example, there can be multiple squeezing rollers 4, and the number of through holes 133 is adapted to the number of squeezing rollers 4. The multiple squeezing rollers 4 can have the same shape or different shapes. This embodiment does not make a specific limitation.

[0116] In this embodiment, by setting two squeezing channels, one squeezing channel is equipped with a scraping component 2 and the other squeezing channel 14 is equipped with a squeezing roller 4, a variety of squeezing methods are provided. Users can flexibly select the appropriate squeezing method to squeeze water out of the wiping material according to the actual scenario.

[0117] In some embodiments, such as Figures 1 to 9 As shown, the extrusion openings formed between the extrusion roller 4 and the opposing side wall 11 are different in size from those formed between the scraper 2 and the opposing side wall 11. The different sizes of the extrusion openings in the two extrusion channels allow for different dewatering effects based on humidity levels.

[0118] For example, the size of the squeezing opening formed between the squeezing roller 4 and the opposing abutting side wall 11 is larger than the size of the squeezing opening formed between the scraping member 2 and the opposing abutting side wall 11. When the user needs a wetter mop, the squeezing opening with a larger width on the squeezing roller 4 can be used to wring out water; when the user needs a drier mop, the squeezing opening with a smaller width on the scraping member 2 can be used to wring out water. The user can flexibly choose the appropriate squeezing opening to wring out water from the wiping object according to the actual scenario. The dual squeezing channels of the wringing mechanism in this embodiment provide different squeezing methods and squeezing openings, making the wringing mechanism suitable for various scenarios.

[0119] Secondly, such as Figure 10 As shown, this utility model also provides a mop, including: a wringing device 10, a mop plate 20, and a mop handle 30. The wringing device 10 is slidably connected to the mop handle 30, and the mop plate 20 is rotatably connected to one end of the mop handle 30; a wringing mechanism is provided at the end of the wringing device 10 near the mop plate 20. This wringing mechanism can be any of the wringing mechanisms provided in the above embodiments. When it is necessary to clean or wring water from the object being wiped, the mop plate 20 is rotated so that its length direction is parallel to the mop handle 30, the gripping part of the wringing device 10 is moved downwards, the wringing mechanism moves downwards, and the mop plate 20 enters the squeezing port to scrape and / or squeeze the object being wiped. The wringing mop provided in this embodiment has a simple structure, is easy to operate, and has a good wringing effect. The wringing mechanism on the mop has mounting holes 131 on the main body 1 for installing the scraper 2. The molding structure is simple, the scraper 2 is easy to install, and the scraper 2 can be stably installed on the main body 1. This ensures that the scraper 2 can work stably when scraping and / or squeezing the wiped object, without loosening or falling off. Furthermore, installing the scraper 2 through the mounting holes 131 will not cause deformation of the main body of the wringing mechanism, making the wringing mechanism structure stable and ensuring a stable wringing effect of the mop.

[0120] Thirdly, this utility model also provides a mop bucket, including: a bucket body and a wringing mechanism disposed at the opening of the bucket body. This wringing mechanism can be any of the wringing mechanisms provided in the above embodiments. When it is necessary to clean the items being wiped or to wring water from the items, the mop blade is rotated so that its length direction is parallel to the mop handle. The mop blade is then inserted into the squeezing port of the wringing mechanism. The mop is moved up and down, and the squeezing port scrapes and / or squeezes the items being wiped to complete the cleaning or wringing process. The mop bucket provided in this embodiment has a simple structure, is easy to operate, and provides good wringing effect. The wringing mechanism on the mop bucket has mounting holes 131 on the main body 1 for installing the scraper 2. The molding structure is simple, the scraper 2 is easy to install, and the scraper 2 can be stably installed on the main body 1. This ensures that the scraper 2 can work stably when scraping and / or squeezing the wiped object, without loosening or falling off. Furthermore, installing the scraper 2 through the mounting holes 131 will not cause deformation of the main body of the wringing mechanism, making the wringing mechanism structure stable and ensuring a stable wringing effect on the mop bucket.
