Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically to a wringing mechanism and a mop. Background Technology

[0002] The wringing mechanism is the core cleaning tool of a mop. It generally includes a wringing frame and a squeegee. The wringing frame has a squeezing nozzle, and the squeegee is rotatably mounted on one side of the squeezing nozzle. By moving the mop blade in the squeezing nozzle, the squeegee can reciprocate to squeeze or scrape the cleaning material on the mop blade to achieve the purpose of cleaning the cleaning material.

[0003] Existing dewatering mechanisms can set the scraping component on the front housing, and then form a squeezing port by assembling the front housing and the rear housing. The front housing and the rear housing are usually fixed by a snap-fit ​​structure.

[0004] However, the force exerted on the scraping parts when the mop blade moves in the squeezing nozzle is relatively large, which can easily cause the front and rear housings to separate, which is not conducive to the long-term use of the mop. Utility Model Content

[0005] In view of this, the present invention provides a wringing mechanism and a mop, which solves the problem that the wringing mechanism in the prior art is not very stable and is not conducive to the long-term use of the mop.

[0006] In a first aspect, this utility model provides a water-squeezing mechanism, including a rear housing, a front housing, a scraping component, and an annular fastening component:

[0007] The rear housing includes a rear plate and mounting wings extending away from the rear plate at both ends; the front housing includes a front cover and fixed wings extending away from the front cover at both ends, the mounting wings of the rear housing and the fixed wings of the front housing are opposite to each other and close to each other, so that the front housing covers the rear housing; the scraping member is disposed on the mounting part, the mounting part being either the mounting wing or the fixed wing, and a squeezing opening is formed between the scraping member and the rear plate for inserting a mop board and cleaning the wiping material on the mop board, the scraping member being used to scrape and / or squeeze the wiping material on the mop board; the outer sides of the mounting wing and the fixed wing away from the squeezing opening are combined to form an annular assembly part, the annular fastener cooperating with the assembly part for connecting the rear housing and the front housing.

[0008] Beneficial Effects: The rear and front housings can be connected by the engagement of the annular assembly portion and the annular fastener located on the outer side of the mounting wing and fixed wing. Since the annular fastener is located on the outer side of the extrusion port, the force exerted by the mop plate on the front or rear housing when the mop plate moves within the extrusion port can be converted into a pulling force on both sides of the annular fastener. This pulling force is perpendicular to the direction of force applied to the annular fastener during installation. Therefore, even if the annular fastener is subjected to this pulling force, it will not detach from the assembly portion. In other words, connecting the rear and front housings from the side via the annular fastener improves the stability of the connection between the front and rear housings, which is beneficial for the long-term use of the wringing mechanism. Furthermore, the annular assembly portion that engages with the annular fastener allows for precise positioning of the fastener, avoiding installation inefficiencies caused by positioning difficulties and improving the overall assembly efficiency of the wringing mechanism.

[0009] In one alternative embodiment, the annular assembly portion is an annular mounting groove, and the annular fastener is installed in the annular mounting groove.

[0010] Beneficial effects: The ring-shaped fastener is installed through the ring-shaped mounting groove, which makes the outer sides of the mounting wing and the fixed wing relatively flat, increasing the aesthetics and preventing dirt from accumulating.

[0011] In one alternative embodiment, the annular fastener is embedded in the annular mounting groove.

[0012] Beneficial effects: By embedding the annular fastener into the annular mounting groove, the annular fastener can be prevented from detaching from the annular mounting groove when subjected to external force, thus improving the stability of the water squeezing mechanism installation.

[0013] In one alternative embodiment, the fixed wing has a covering protrusion on its outer side away from the extrusion port; when the annular fastener is installed in the mounting groove, the covering protrusion extends from the hollow area of ​​the annular fastener.

[0014] Beneficial effects: The protruding cover can position the ring-shaped fastener during installation, avoiding difficulties in positioning the fastener during assembly; at the same time, after the ring-shaped fastener is installed, the protruding cover extends from the hollow area of ​​the ring-shaped fastener, making the outer sides of the mounting wing and the fixing wing relatively flat, reducing the accumulation of dirt.

[0015] In one alternative embodiment, when the annular fastener is installed in the annular mounting groove, the inner ring sidewall of the annular fastener abuts against the outer peripheral sidewall of the covering protrusion.

[0016] Beneficial effects: The inner ring sidewall of the annular fastener abuts against the outer peripheral sidewall of the covering protrusion, which can avoid gaps between the annular fastener and the covering protrusion, further preventing dirt from accumulating; at the same time, it also improves the stability of the annular fastener, making it less likely for the annular fastener to detach from the mounting wing and the fixing wing.

[0017] In one optional embodiment, a portion of the mounting groove is provided on the outer side of the mounting wing, and another portion of the mounting groove is provided on the outer side of the fixed wing; after the mounting wing and the fixed wing abut against each other, they are spliced ​​together to form the complete annular mounting groove.

[0018] Beneficial effects: The combination of the mounting wing and the fixed wing forms an annular mounting groove. When the annular fastener is placed on the outside of the mounting wing and the fixed wing, it engages in the annular mounting groove, thereby further improving the stability of the fit between the mounting wing and the fixed wing and strengthening the connection between the annular fastener, the mounting wing and the fixed wing.

[0019] In one optional embodiment, the outer periphery of the mounting wing is provided with a first flange, which forms part of the outer sidewall of the annular mounting groove; the outer periphery of the fixed wing is provided with a second flange, which forms another part of the outer sidewall of the annular mounting groove.

[0020] Beneficial effects: Through the above design, when the annular fastener is closed on the outside of the mounting wing and the fixed wing, the outer periphery of the annular fastener can abut against the outer flange of the mounting wing and the fixed wing respectively, which further strengthens the connection between the annular fastener, the mounting wing and the fixed wing, and at the same time avoids the problem that the outer periphery of the annular fastener is easy to lift up and affect the aesthetics.

[0021] In one alternative embodiment, the annular assembly portion is an annular protrusion, and the annular fastener is sleeved on the protrusion.

[0022] Beneficial effects: The annular fastener can also be installed on the outside of the mounting wing and the fixed wing via the annular protrusion, providing an alternative installation method. The annular protrusion can also position the installation of the annular fastener, improving the assembly efficiency of the dewatering mechanism.

[0023] In one alternative embodiment, the annular fastener engages with both the mounting wing and the fixed wing.

[0024] Beneficial effects: The ring-shaped fasteners, by engaging with the mounting wing and the fixed wing respectively, not only achieve effective fixation but also make assembly and disassembly more convenient and quick.

[0025] In one alternative implementation, the fixed wing and the mounting wing at least partially overlap and abut against each other.

[0026] Beneficial effects: The fixed wing and the mounting wing at least partially overlap and abut each other, allowing the fixed wing and the mounting wing to mutually limit each other, which facilitates installation.

[0027] In one alternative embodiment, when the scraping member is disposed on the mounting wing, the fixed wing is positioned to abut against the outer side of the mounting wing.

[0028] Beneficial effects: When the scraper is installed on the mounting wing, the fixed wing limiter is located on the outside of the mounting wing, which can effectively limit the mounting wing and prevent the mounting wing from deforming under force and expanding outward, thus preventing the scraper from falling off.

[0030] Beneficial effects: By engaging the snap-fit ​​post with the first and second mounting holes, the mounting wing and the fixed wing can be effectively limited in the axial direction, and displacement of the mounting wing and the fixed wing can be prevented. This makes the connection between the annular fastener, the mounting wing and the fixed wing more secure and stable, and less prone to detachment.

[0031] In one optional embodiment, the end of the snap-fit ​​post is provided with an elastic buckle. When the snap-fit ​​post is inserted into the first mounting hole and the second mounting hole, the elastic buckle closes. When the end of the snap-fit ​​post passes through the first mounting hole and the second mounting hole, the elastic buckle opens to achieve fixation.

[0032] Beneficial effects: The elastic buckle provided at the end of the snap-fit ​​post has a closed contracted state and an open snap-fit ​​state. When the snap-fit ​​post is inserted into the first mounting hole and the second mounting hole, the elastic buckle is in the closed contracted state, which facilitates the insertion and engagement of the snap-fit ​​post with the first mounting hole and the second mounting hole. When the snap-fit ​​post passes through the first mounting hole and the second mounting hole, the elastic buckle expands outward to the snap-fit ​​state under its own elastic force and is limited to the inside of the mounting wing, thereby achieving effective fixation of the annular fastener, the fixed wing, and the mounting wing.

[0033] In one optional embodiment, the mounting wing is provided with two first mounting holes spaced apart along the insertion direction of the mop plate in the squeezing port, and the fixing wing is provided with two second mounting holes spaced apart along the insertion direction. When the fixing wing and the mounting wing partially overlap and abut, the two first mounting holes and the two second mounting holes are respectively aligned to form two aligned hole positions. The annular fastener is provided with two snap-fit ​​pins, and the two snap-fit ​​pins are respectively inserted into the two aligned hole positions and snapped in place.

[0034] Beneficial effects: The cooperation of two sets of aligned holes and snap-fit ​​pins can prevent the mounting wing and fixed wing from rotating and shifting, further improving the stability of the engagement between the annular fastener and the fixed wing and mounting wing, and ensuring that the mounting wing can maintain strong resistance to deformation throughout the entire process of inserting the mop into the squeezing port.

[0035] In one optional embodiment, the annular assembly part is an annular mounting groove; the outer edge of the annular fastener is provided with multiple buckles, and the sidewall of the annular mounting groove is provided with multiple slots, and the annular fastener is engaged with the mounting wing and the fixed wing respectively through the buckles and the slots.

[0036] In one alternative embodiment, at least one of the slots is provided on the mounting wing and at least one of the slots is provided on the fixed wing.

[0037] Beneficial effects: The ring-shaped fastener can also engage with the mounting wing and the fixed wing through slots and buckles, providing another engagement method and improving the stability of the connection between the front and rear housings.

[0038] In one optional embodiment, a positioning part is provided between the annular fastener and the annular assembly part, the positioning part being used to position the fastener and the assembly part for installation.

[0039] In one optional embodiment, the positioning part includes a positioning post disposed on one of the annular fastener and the annular assembly part, and a positioning hole disposed on the other; when the annular fastener and the annular assembly part are fitted together, the positioning post is inserted into the positioning hole.

[0040] Beneficial effects: By setting the above positioning part, it is helpful to install the fastener and avoid the situation that the fastener cannot be effectively assembled due to incorrect installation direction when assembling the squeezing mechanism.

[0137] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0138] The following is combined with Figures 1 to 16 The following describes embodiments of the present invention.

[0139] Firstly, this utility model provides a water-squeezing mechanism 10, such as... Figure 1 and Figure 4 As shown, the water-squeezing mechanism 10 includes a rear housing 11, a front housing 13, a scraping member 12, and an annular fastening member 14.

[0140] The rear housing 11 includes a rear plate 111 and mounting wings 112 at both ends of the rear plate 111, with the mounting wings 112 extending away from the rear plate 111. The front housing 13 includes a front cover plate 131 and fixed wings 132 at both ends of the front cover plate 131, with the fixed wings 132 extending away from the front cover plate 131. When the dewatering mechanism is installed, the mounting wings 112 of the rear housing 11 and the fixed wings 132 of the front housing 13 face each other and move closer to each other, so that the front housing 13 covers the rear housing 11.

[0141] The scraping member 12 of the wringing mechanism 10 is mounted on a mounting portion, which can be either a mounting wing 112 or a fixed wing 132. A squeezing opening 101 is formed between the scraping member 12 and the rear plate 111 for inserting the mop plate 60 and cleaning the wiping material on the mop plate 60. The scraping member 12 is used to scrape and / or squeeze the wiping material on the mop plate 60. An annular assembly portion is formed on the outer side of the mounting wing 112 and the fixed wing 132 away from the squeezing opening 101. An annular fastener 14 is fitted into the annular assembly portion to connect the rear housing 11 and the front housing 13.

[0142] For example, when the scraper 12 is disposed on the mounting wing 112, the front housing 13 covers the rear housing 11. This allows the fixed wing 132 to be positioned and abut against the outside of the mounting wing 112. This prevents the mop plate 60 from applying force to the scraper 12 when the squeezing port 101 moves, causing the scraper 12 to move away from the squeezing port 101, resulting in deformation of the mounting wing 112 and subsequent detachment of the scraper 12 from the mounting wing 112. Similarly, when the scraper 12 is disposed on the fixed wing 132, the front housing 13 covers the rear housing 11. This allows the mounting wing 112 to be positioned and abut against the outside of the fixed wing 132. This prevents the mop plate 60 from applying force to the scraper 12 when the squeezing port 101 moves, causing the scraper 12 to move away from the squeezing port 101, resulting in deformation of the fixed wing 132 and subsequent detachment of the scraper 12 from the fixed wing 132. Alternatively, when the front housing 13 covers the rear housing 11, the ends of the mounting wing 112 and the fixed wing 132 can be opposite to each other and abut against each other, or the ends of the mounting wing 112 and the fixed wing 132 are opposite to each other and there is a certain distance between them. The mounting wing 112 and the fixed wing 132 are connected by the annular fastener 14 on the outer side of the mounting wing 112 and the fixed wing 132.

[0143] It should be noted that when the scraping component 12 is installed at the root of the fixed wing 132, the front housing 13 covers the rear housing 11, which allows the fixed wing 132 to be limited and abutted against the outside of the mounting wing 112, that is, the end of the mounting wing 112 can limit the scraping component 12.

[0144] The rear housing 11 and the front housing 13 can be connected by the engagement of the annular mounting portion provided on the outer side of the mounting wing 112 and the fixed wing 132 with the annular fastener 14. Since the annular fastener 14 is provided on the outer side of the squeezing port 101, when the mop plate 60 moves in the squeezing port 101, the force exerted by the mop plate 60 on the front housing 13 or the rear housing 11 can be converted into a pulling force on the front and rear sides of the annular fastener 14. The direction of this pulling force is perpendicular to the direction of the force applied to the annular fastener 14 during installation. Therefore, even if the annular fastener 14 is subjected to the above-mentioned pulling force, it will not cause the annular fastener 14 to detach from the mounting portion. That is, by connecting the rear housing 11 and the front housing 13 from the side through the annular fastener 14, the stability of the connection between the front and rear housings can be improved, which is beneficial to the long-term use of the squeezing mechanism 10. Furthermore, the annular assembly part that cooperates with the annular fastener 14 can be used to position the installation position of the annular fastener 14, avoiding the situation of low installation efficiency due to positioning difficulties during installation, and improving the assembly efficiency of the entire squeezing mechanism.

[0145] In one alternative implementation, such as Figure 9 As shown, the annular assembly portion can be an annular mounting groove 70, and the annular fastener 14 is installed in the annular mounting groove 70. For example, when the front housing 13 covers the rear housing 11, the mounting wing 112 and the fixed wing 132 are arranged opposite each other, and their outer sides away from the extrusion port 101 combine to form a mounting area. The annular mounting groove 70 can be provided in this mounting area; for example, it can be provided along the edge of the mounting area, near the center of the mounting area, or at other locations within the mounting area. It should be noted that at least a portion of the annular mounting groove 70 is provided on the mounting wing 112, and another portion is provided on the fixed wing 132. For example, if the front housing 13 covers the rear housing 11, and there is a certain distance between the mounting wing 112 and the fixed wing 132, then the mounting area can be discontinuous. The mounting wing 112 is provided with a partial annular mounting groove 70, and the fixed wing 132 is provided with another part of the annular mounting groove 70. The two parts of the mounting groove 70 are combined to form a complete discontinuous annular mounting groove 70. Although the annular mounting groove 70 is discontinuous, it is still annular as a whole.

[0146] The annular fastener 14 is installed through the annular mounting groove 70, making the outer sides of the mounting wing 112 and the fixed wing 132 relatively flat. That is, the annular fastener 14 can fill the annular mounting groove 70, increasing aesthetics and preventing dirt accumulation. Optionally, the annular fastener 14 can also protrude from the mounting groove 70, forming an aesthetically pleasing shape, while preventing the mounting wing 112 or the fixed wing 132 from being directly impacted by external objects and damaged.

[0147] In an optional embodiment, the annular fastener 14 can also be embedded in the annular mounting groove 70, that is, the shape of the annular mounting groove 70 matches the annular fastener 14, so that the annular fastener 14 can be precisely embedded in the annular mounting groove 70. This can prevent the fastener 14 from dislodging from the annular mounting groove 70 when subjected to external force, that is, prevent the edge of the annular fastener 14 from lifting when subjected to collision or force from external objects, which would cause the annular fastener 14 to dislodge from the annular mounting groove 70, thereby improving the stability of the dewatering mechanism installation.

[0148] In one alternative implementation, such as Figure 6 As shown, a covering protrusion 1322 is provided on the outer side of the fixed wing 132 away from the extrusion port 101. The covering protrusion 1322 can be smaller than or equal to the hollow area of ​​the annular fastener 14, so that when the annular fastener 14 is installed in the annular mounting groove 70, the covering protrusion 1322 extends out from the hollow area of ​​the annular fastener 14. The covering protrusion 1322 can play a positioning role in the installation of the annular fastener 14, avoiding the situation where the annular fastener 14 is difficult to position during assembly; at the same time, after the annular fastener 14 is installed, the covering protrusion 1322 extending out from the hollow area of ​​the annular fastener 14 can make the outer sides of the mounting wing 112 and the fixed wing 132 relatively flat, reducing the possibility of dirt accumulation.

[0149] Alternatively, the center of the covering protrusion 1322 may be slightly bulging, and its edges may be inclined toward the mounting wing 112 or the fixed wing 132, meaning that the edge of the covering protrusion 1322 can form a guide surface. When installing the annular fastener 14, it is only necessary to align the hollow area of ​​the annular fastener 14 with the covering protrusion 1322 and bring the annular fastener 14 closer to the fixed wing 132 or the mounting wing 112. Even if the hollow area is not aligned with the covering protrusion 1322, after the annular fastener 14 contacts the covering protrusion 1322, under the guidance of the guide surface, the annular fastener 14 can also be fitted onto the covering protrusion 1322. That is, the covering protrusion 1322 can extend from the hollow area of ​​the annular fastener 14, allowing the annular fastener 14 to be installed into the mounting groove 70.

[0150] Alternatively, when the scraper 12 is movably mounted on the mounting wing 112, for example, when the scraper 12 rotates or slides on the mounting wing 112, the end of the scraper 12 may penetrate the mounting wing 112. If the end of the scraper 12 contacts the direct fixing wing 132, the fixing wing 132 may interfere with the movement of the scraper 12, resulting in greater friction and preventing the scraper 12 from rotating or sliding smoothly. In this case, the covering protrusion 1322 provided on the fixing wing 132 can also cover the outside of the scraper 12. By using the covering protrusion 1322 to avoid the end of the scraper 12, on the one hand, the scraper 12 is prevented from being unable to move smoothly due to the contact of the fixing wing; on the other hand, even if the scraper 12 does not need to move, the covering protrusion 1322 can also prevent the force from being directly transmitted to the scraper 12 when subjected to external impact, thus preventing damage to the scraper 12.

[0151] In one alternative implementation, such as Figure 5 As shown, when the annular fastener 14 is installed in the annular mounting groove, the inner ring sidewall of the annular fastener 14 abuts against the outer peripheral sidewall of the covering protrusion 1322, which can avoid the situation where there is a gap between the annular fastener 14 and the covering protrusion 1322, further preventing dirt from accumulating; at the same time, it also improves the stability of the annular fastener 14, making it less likely for the annular fastener 14 to detach from the mounting wing 112 and the fixing wing 132.

[0152] In one optional embodiment, a portion of the mounting groove 70 is provided on the outer side of the mounting wing 112, and another portion of the mounting groove 70 is provided on the outer side of the fixed wing 132; after the mounting wing 112 and the fixed wing 132 abut against each other, they are spliced ​​together to form a complete annular mounting groove 70.

[0153] For example, when the scraper 12 is mounted on the mounting wing 112, most of the mounting groove 70 is located on the fixed wing 132, and a small portion is located on the mounting wing 112. After the fixed wing 132 is positioned and abuts against the outer side of the mounting wing 112, the two parts are joined together to form a complete annular mounting groove 70. Alternatively, the fixed wing 132 is provided with most of the annular mounting groove 70 and a covering protrusion 1322. The mounting wing 112 is planar, meaning that the mounting wing 112 is provided with the outer side wall and bottom wall of another part of the mounting groove 70. After the fixed wing 132 is positioned and abuts against the outer side of the mounting wing 112, the covering protrusion 1322 and the planar surface of the mounting wing 112 form another small part of the annular mounting groove 70. That is, the outer side wall of the covering protrusion 1322 forms the inner side wall of another part of the mounting groove 70 provided on the mounting wing 112. After the two parts of the mounting groove 70 are joined together, a complete annular mounting groove 70 is formed.

[0154] Similarly, when the scraper 12 is set on the fixed wing 132, most of the mounting groove 70 is set on the mounting wing 112 and a small part is set on the fixed wing 132. The mounting wing 112 is positioned and abuts against the fixed wing 132, forming a complete annular mounting groove 70. Alternatively, the mounting wing 112 is provided with most of the annular mounting groove 70 and the covering protrusion 1322. The fixed wing 132 is flat, that is, the fixed wing 132 is provided with the outer side wall and bottom wall of another part of the annular mounting groove 70. The mounting wing 112 is positioned and abuts against the fixed wing 132. The covering protrusion 1322 and the flat surface of the fixed wing 132 form another small part of the annular mounting groove 70. That is, the outer side wall of the covering protrusion 1322 forms the inner side wall of another part of the mounting groove 70 provided on the fixed wing 132. After the two parts of the mounting groove 70 are joined together, a complete annular mounting groove 70 can be formed.

[0155] Alternatively, when the end of the mounting wing 112 is opposite to and abuts against the end of the fixed wing 132, a portion of the mounting wing 112 is provided with an annular mounting groove 70, and another portion of the fixed wing 132 is provided with an annular mounting groove 70. After the end of the mounting wing 112 abuts against the end of the fixed wing 132, the two portions are joined together to form a complete annular mounting groove 70. If the ends of the mounting wing 112 and the fixed wing 132 are opposite to each other and there is a certain distance between them, a portion of the mounting wing 112 is provided with an annular mounting groove 70, and another portion of the fixed wing 132 is provided with an annular mounting groove 70. The two portions can be joined together to form a discontinuous annular mounting groove 70.

[0156] The mounting wing 112 and the fixed wing 132 combine to form an annular mounting groove 70. When the annular fastener is placed on the outside of the mounting wing 112 and the fixed wing 132, it engages in the annular mounting groove 70, which can further improve the stability of the fit between the mounting wing 112 and the fixed wing 132 and strengthen the connection between the annular fastener 14, the mounting wing 112 and the fixed wing 132.

[0157] In one alternative implementation, such as Figure 6 As shown, the outer periphery of the mounting wing 112 is provided with a first flange 1122, which forms part of the outer wall of the annular mounting groove 70; the outer periphery of the fixed wing 132 is provided with a second flange 1323, which forms another part of the outer wall of the annular mounting groove 70. Through this design, when the annular fastener 14 is closed on the outer sides of the mounting wing 112 and the fixed wing 132, the outer periphery of the annular fastener 14 can abut against the flanges of the outer periphery of the mounting wing 112 and the fixed wing 132 respectively, further strengthening the connection between the annular fastener 14, the mounting wing 112, and the fixed wing 132. At the same time, it also avoids the problem of the outer periphery of the annular fastener 14 easily lifting up and affecting aesthetics.

[0158] In one alternative embodiment, the annular assembly portion can be an annular protrusion, and the annular fastener 14 can be fitted onto the annular protrusion.

[0159] For example, when the front housing 13 covers the rear housing 11, the mounting wing 112 and the fixed wing 132 are arranged opposite each other and may partially overlap, so that the outer sides of the two, away from the extrusion port 101, combine to form a mounting area. The annular protrusion can be provided in this mounting area, for example, it can be provided along the edge of the mounting area, or it can be provided near the center of the mounting area, or it can be provided at other positions in the mounting area. It should be noted that at least a portion of the annular protrusion is provided on the mounting wing 112 and another portion is provided on the fixed wing 132. For example, if there is a certain distance between the mounting wing 112 and the fixed wing 132 when the front housing 13 covers the rear housing 11, then the mounting area can be discontinuous. The mounting wing 112 is provided with a partial annular protrusion, and the fixed wing 132 is provided with another part of the annular protrusion. The two parts combine to form a complete discontinuous annular protrusion. Although the annular protrusion is discontinuous, the whole is still annular.

[0160] The annular fastener 14 is installed on the outside of the mounting wing 112 and the fixed wing 132 via an annular protrusion. That is, the annular fastener 14 protrudes from the mounting area, protecting the mounting wing 112 or the fixed wing 132 from direct impact by external objects, thus preventing damage. Simultaneously, the annular protrusion also positions the annular fastener 14 during installation, improving the assembly efficiency of the dewatering mechanism 10.

[0161] In one alternative embodiment, the annular fastener 14 can be snapped into the mounting wing 112 and the fixed wing 132 respectively, which makes the mounting wing 112 and the fixed wing 132 more convenient and quick to install and remove while effectively fixing them.

[0162] For example, when the front housing 13 covers the rear housing 11, if there is an overlapping area between the mounting wing 112 and the fixed wing 132, the annular fastener 14 can engage with both the mounting wing 112 and the fixed wing 132 in that overlapping area. If the ends of the mounting wing 112 and the fixed wing 132 abut against each other, or if the ends of the mounting wing 112 and the fixed wing 132 are positioned opposite each other but with a gap in between, one end of the annular fastener 14 engages with the mounting wing 112 and the other end engages with the fixed wing 132, thereby achieving a connection between the mounting wing 112 and the fixed wing 132.

[0163] In one alternative implementation, the fixed wing 132 and the mounting wing 112 can at least partially overlap and abut, so that the fixed wing 132 and the mounting wing 112 can mutually limit each other, facilitating installation.

[0164] For example, when the scraper 12 is disposed on the mounting wing 112, the fixed wing 132 can be limited and abutted against the outside of the mounting wing 112, and partially overlaps with the mounting wing 112. That is, the fixed wing 132 effectively limits the mounting wing 112, preventing the mounting wing 112 from deforming under force and expanding outward, thus preventing the scraper 12 from detaching from the mounting wing 112. Alternatively, when the scraper 12 is disposed on the fixed wing 132, the mounting wing 112 can be limited and abutted against the outside of the fixed wing 132, and partially overlaps with the fixed wing 132. That is, the mounting wing 112 effectively limits the fixed wing 132, preventing the fixed wing 132 from deforming under force and expanding outward, thus preventing the scraper 12 from detaching from the fixed wing 132. Alternatively, when the scraper 12 is disposed at the root of the fixed wing 132, the fixed wing 132 can be limited and abutted against the outside of the mounting wing 112, facilitating the limitation of the scraper 12 by the mounting wing 112.

[0165] In one alternative implementation, such as Figure 6 , Figure 9 , Figure 10 As shown, the mounting wing 112 is provided with a first mounting hole 1121, and the fixed wing 132 is provided with a second mounting hole 1321; when the fixed wing 132 abuts against the mounting wing 112, the first mounting hole 1121 and the second mounting hole 1321 are aligned; the annular fastener 14 is provided with a snap-fit ​​post 141, and when the annular fastener 14 is installed on the outside of the mounting wing 112 and the fixed wing 132, the snap-fit ​​post 141 extends into the aligned first mounting hole 1121 and the second mounting hole 1321, and snaps into the first mounting hole 1121 and the second mounting hole 1321 respectively.

[0166] In the above embodiment, by engaging the snap-fit ​​post 141 with the first mounting hole 1121 and the second mounting hole 1321, the mounting wing 112 and the fixed wing 132 can be effectively limited, preventing displacement of the mounting wing 112 and the fixed wing 132, making the connection between the fastener 14, the mounting wing 112 and the fixed wing 132 more secure and stable, and less prone to detachment.

[0167] For example, if the mounting wing 112 and the fixed wing 132 have partially overlapping areas, then the first mounting hole 1121 can be opened in the overlapping area of ​​the mounting wing 112, and the second mounting hole 1321 can be opened in the overlapping area of ​​the fixed wing 132. During assembly, the fixed wing 132 is limited to the outside of the mounting wing 112. At this time, the first mounting hole 1121 and the second mounting hole 1321 are aligned. Then, the snap-fit ​​pin 141 of the annular fastener 14 is sequentially inserted into the second mounting hole 1321 and the first mounting hole 1121, and snapped into the second mounting hole 1321 and the first mounting hole 1121 respectively, thereby realizing the connection between the fixed wing 132 and the mounting wing 112.

[0168] In one alternative implementation, such as Figure 9 As shown, the end of the snap-fit ​​post 141 is provided with an elastic buckle 1411. When the snap-fit ​​post 141 is inserted into the first mounting hole 1121 and the second mounting hole 1321, the elastic buckle 1411 closes. When the end of the snap-fit ​​post 141 passes through the first mounting hole 1121 and the second mounting hole 1321, the elastic buckle 1411 opens to achieve fixation.

[0169] In the above embodiment, the elastic buckle 1411 provided at the end of the snap-fit ​​post 141 has a closed contracted state and an open snap-fit ​​state. When the snap-fit ​​post 141 is inserted into the first mounting hole 1121 and the second mounting hole 1321, the elastic buckle 1411 is in the closed contracted state to facilitate the snap-fit ​​post 141 to pass through and cooperate with the first mounting hole 1121 and the second mounting hole 1321. When the snap-fit ​​post 141 passes through the first mounting hole 1121 and the second mounting hole 1321, the elastic buckle 1411 expands outward to the snap-fit ​​state under its own elastic force and is limited to the inner side of the mounting wing 112, thereby realizing the effective fixation of the annular fastener 14, the fixing wing 132, and the mounting wing 112.

[0170] In one alternative implementation, such as Figure 6 , Figure 9 , Figure 10 As shown, the mounting wing 112 has two first mounting holes 1121 spaced apart along the insertion direction of the mop plate in the squeezing port 101, and the fixed wing 132 has two second mounting holes 1321 spaced apart along the insertion direction. When the fixed wing 132 abuts against the mounting wing 112, the two first mounting holes 1121 and the two second mounting holes 1321 are aligned respectively, forming two aligned hole positions 103; the annular fastener 14 is provided with two snap-fit ​​pins 141, and the two snap-fit ​​pins 141 are inserted into the two aligned hole positions 103 and snapped together.

[0171] In the above embodiment, the cooperation of two sets of alignment holes 103 and snap-fit ​​posts 141 can prevent the mounting wing 112 and the fixed wing 132 from rotating, further improving the stability of the engagement between the annular fastener 14 and the fixed wing 132 and the mounting wing 112, and ensuring that the mounting wing 112 can maintain strong anti-deformation ability throughout the entire process of inserting the mop into the squeezing port 101.

[0172] Specifically, the mounting wing 112 and the fixed wing 132 have partially overlapping areas. Two first mounting holes 1121 are spaced apart at both ends of the overlapping area of ​​the mounting wing 112 along the insertion direction of the mop 200, and two second mounting holes 1321 are spaced apart at both ends of the fixed wing 132 along the insertion direction of the mop 200. During assembly, the fixed wing 132 is positioned on the outside of the mounting wing 112, and the two first mounting holes 1121 are aligned with the two second mounting holes 1321, respectively, and engage with the two locking posts 141 of the annular fastener 14. This arrangement of the two locking posts 141 along the insertion direction of the mop 200 prevents rotational displacement of the mounting wing 112 and the fixed wing 132.

[0173] In one alternative implementation, such as Figure 11 and Figure 12 As shown, the annular assembly part can be an annular mounting groove 70. The outer edge of the annular fastener 14 is provided with multiple snap fasteners 143, and the sidewall of the annular mounting groove 70 is provided with multiple slots. At least one slot is provided on the mounting wing 112, and at least one slot is provided on the fixing wing 132. The annular fastener 14 can then be engaged with the mounting wing 112 and the fixing wing 132 via the snap fasteners and slots, respectively.

[0174] For example, when the front housing 13 covers the rear housing 11, if the mounting wing 112 and the fixed wing 132 have a partially overlapping area, the multiple slots can be set in the overlapping area. When the annular fastener 14 is installed in the annular mounting groove 70, the buckle on the annular fastener 14 can penetrate the mounting wing 112 and engage with the fixed wing 132, or penetrate the fixed wing 132 and engage with the mounting wing 112. If the ends of the mounting wing 112 and the fixed wing 132 abut against each other, or if there is a gap between the ends of the mounting wing 112 and the fixed wing 132, then a portion of the multiple slots are set in the mounting wing 112, and another portion is set in the fixed wing 132. The multiple buckles on the annular fastener 14 can engage with the slots on the mounting wing 112 and the fixed wing 132 respectively, realizing the connection between the mounting wing 112 and the fixed wing 132, and improving the stability of the connection between the front housing and the rear housing.

[0175] In one optional embodiment, a positioning part is provided between the annular fastener 14 and the annular assembly portion. The positioning part is used to position the annular fastener 14 and the annular assembly portion during installation. For example, see [reference needed]. Figure 11 and Figure 12 As shown, the positioning part may include a positioning post 142 provided on one of the annular fastener 14 and the annular assembly part, and a positioning hole 15 provided on the other; when the annular fastener 14 is installed in conjunction with the annular assembly part, the positioning post 142 is inserted into the positioning hole 15.

[0176] For example, the annular fastener 14 may have two positioning posts 142 spaced apart along the direction in which the mop plate 60 is inserted into the squeezing port 101. When the front housing 13 covers the rear housing 11, if the mounting wing 112 and the fixed wing 132 have partially overlapping areas, and the annular assembly part is an annular mounting groove 70, the portion of the annular mounting groove 70 located in the overlapping area has two positioning holes 15 spaced apart along the direction in which the mop plate 60 is inserted into the squeezing port 101. These two positioning holes can penetrate the mounting wing 112 and the fixed wing 132. When the annular fastener 14 is installed to the annular assembly part, the two positioning posts 142 can be inserted into the two positioning holes 15 respectively. This positioning part can limit the installation direction and position of the annular fastener 14, avoiding the situation where the installation direction of the annular fastener 14 is incorrect and cannot be effectively assembled when assembling the squeezing mechanism 10. At the same time, it can also limit the linear or rotational displacement between the mounting wing 112 and the fixed wing 132.

[0177] In one alternative implementation, the fixed wing 132 is snapped into the mounting wing 112.

[0178] In the above embodiments, when assembling the front housing 13 and the rear housing 11, the fixed wing 132 is first snapped into the mounting wing 112 to pre-fix them before being fixed by the annular fastener 14. This can further improve the stability of the engagement between the fixed wing 132 and the mounting wing 112, reduce the risk of deformation of the mounting wing 112, and effectively avoid the problem that the fastener 14 is not easy to fix due to the sliding between the fixed wing 132 and the mounting wing 112.

[0179] In one alternative embodiment, the fixed wing 132 and the mounting wing 112 are fixedly engaged by a snap-fit ​​protrusion 1123 and a snap-fit ​​groove 1324; wherein, one of the snap-fit ​​protrusion 1123 and the snap-fit ​​groove 1324 is provided on the mounting wing 112; and the other of the snap-fit ​​protrusion 1123 and the snap-fit ​​groove 1324 is provided on the fixed wing 132.

[0180] For example, such as Figure 10As shown, the snap-fit ​​protrusion 1123 can be provided on the mounting wing 112, and the snap-fit ​​groove 1324 is provided on the fixed wing 132. The snap-fit ​​groove 1324 can pass through the fixed wing 132 or be provided on the inner side of the fixed wing 132. When the fixed wing 132 is limited to abutting against the outer side of the mounting wing 112, the snap-fit ​​protrusion 1123 and the snap-fit ​​groove 1324 snap together.

[0181] It should be noted that in this embodiment, the fixed wing 132 and the mounting wing 112 are not limited to being fixed by snap-fit ​​protrusion 1123 and snap-fit ​​groove 1324, but can also be fixed by snap-fit ​​structures such as claws, buckles, and snap-fit ​​bosses.

[0182] For example, the end of the mounting wing 112 can be snapped onto the root of the fixed wing 132, which makes the connection between the fixed wing 132 and the mounting wing 112 more secure and stable than snapping onto the end of the fixed wing 132.

[0183] In this embodiment, the mounting wing 112 includes a mounting wing 112 body connected to the rear plate 111 and an extension 1120 at the end of the mounting wing 112 body. A snap-fit ​​protrusion 1123 is provided on the outer side of the extension 1120, and a snap-fit ​​groove 1324 is provided at the root of the fixed wing 132. The extension 1120 can extend into the root of the fixed wing 132 and snap-fit ​​with the snap-fit ​​groove 1324. Optionally, the extension 1120 is a protruding plate protruding from the middle of the mounting wing 112 body.

[0184] In some embodiments, the scraping member 12 has a connecting end adapted to connect with the mounting wing 112; the mounting wing 112 has a snap-fit ​​protrusion 1123, the fixed wing 132 has a snap-fit ​​groove 1324, and the connecting end is located between the snap-fit ​​protrusion 1123 on the mounting wing 112 and the rear plate 111. Alternatively, in another embodiment, the mounting wing 112 has a snap-fit ​​groove 1324, the fixed wing 132 has a snap-fit ​​protrusion 1123, and the connecting end is located between the snap-fit ​​groove 13243 on the mounting wing 112 and the rear plate 111.

[0185] In the above embodiments, such as Figure 10 As shown, the root of the mounting wing 112 is fixedly connected to the rear plate 111, and the end of the mounting wing 112 is snapped and fixed to the fixed wing 132. The scraping component 12 is disposed between the root of the mounting wing 112 and the snapping position between the mounting wing 112 and the fixed wing 132, thereby providing more stable and reliable support and limiting to the mounting wing 112 from both sides of the force point where the scraping component 12 is connected to the mounting wing 112. This effectively prevents the scraping component from being squeezed by the force of the mounting wing 112, causing the two mounting wings 112 to move away from each other and deform.

[0186] In one alternative embodiment, one of the mounting part and the scraping member 12 is provided with a groove 1124, and the other is provided with a guide block 121. The guide block 121 is disposed in the groove 1124 and slides along the groove 1124.

[0187] For example, such as Figure 10 As shown, the scraping member 12 can be disposed on the mounting wing 112, which has a groove 1124. The guide block 121 disposed at the end of the scraping member 12 can be inserted into the groove 1124 and slide along the groove 1124. The guide block 121 can be the end of the scraping member 12, such as the end of the extrusion roller or the end of the scraper; or it can be a separate block structure with a guiding function disposed at the end of the scraping member 12.

[0188] Or, such as Figure 11 As shown, the scraping member 12 can be mounted on the fixed wing 132, which is provided with a groove 1124. The guide block 121 at the end of the scraping member 12 can be inserted into the groove 1124 and slide along the groove 1124.

[0189] In one optional embodiment, guide blocks 121 are provided at both ends of the scraping member 12, and grooves 1124 are provided on both sides of the mounting portion of the extrusion port 101.

[0190] For example, both ends of the scraper 12 are set in the groove 1124 via guide blocks 121. When the mop plate 60 is inserted into the squeezing port 101 and moves in the squeezing port 101, the wiping material on the mop plate 60 applies force to the scraper 12, which can drive both ends of the scraper 12 to slide along the groove 1124. This avoids the problem that the mop plate 60 is not easy to enter the squeezing port 101 due to hard friction when the wiping material comes into contact with the scraper 12, and the end of the wiping material is easily damaged.

[0191] In one embodiment, the groove 1124 can be inclined along the direction in which the mop board is inserted into the squeezing port 101, and the distance between it and the rear plate 111 gradually decreases. At this time, the size of the squeezing port 101 can be adjusted by moving the mop board 60 in the squeezing port 101. For example, when the mop board 60 is inserted into the squeezing port 101 from bottom to top, the squeezing port 101 is larger. When the mop board 60 is inserted into the squeezing port 101 and continues to move upward, the wiping material drives the scraping member 12 to slide along the groove 1124. At this time, the squeezing port 101 gradually decreases, and the squeezing force provided by the scraping member 12 to the wiping material also increases, which is convenient for cleaning the wiping material. When the mop board 60 moves in the opposite direction, the wiping material drives the scraping member 12 to slide in the opposite direction along the groove 1124. At this time, the squeezing port 101 gradually decreases, which is convenient for the mop board 60 to disengage from the squeezing port 101.

[0192] In one optional embodiment, a limiting groove 133 is provided on the mounting part, and the limiting groove 133 is provided with an opening 1331; the end of the scraping member 12 is installed into the limiting groove 133 through the opening 1331.

[0193] For example, such as Figure 13 As shown, taking the fixed wing 132 as an example, the fixed wing 132 has a limiting groove 133 on its inner side. The limiting groove 133 can be located at the root of the fixed wing 132, and the limiting groove 133 has an opening 1331 on the side near the extrusion port 101. For example, the inner side of the root of the fixed wing 132 has a boss, and the side of the boss near the extrusion port 101 is recessed in a direction away from the extrusion port 101 to form a limiting groove 133 with an opening 1331. The end of the scraping member 12 can move into the limiting groove 133 through the opening 1331, so that the end is limited in the limiting groove 133, improving the ease of installation of the scraping member 12. Since the direction of the force applied to the scraping member 12 by the wiping material after the mop plate 60 is inserted into the extrusion port 101 is opposite to the direction in which the scraping member 12 comes out of the limiting groove 133, normal use will not usually cause the scraping member 12 to come out of the limiting groove 133.

[0194] Alternatively, the mounting part can be a mounting wing 122, in which case the mounting wing 122 is provided with a limiting groove 133. The limiting groove can be located at the end of the mounting wing 122, and the limiting groove 133 is provided with an opening 1331. For example, the end face of the end of the mounting wing 122 is recessed in the direction close to the extrusion port 101 to form a limiting groove 133 with an opening 1331. Alternatively, the limiting groove can be located on the inner side of the mounting wing 122. For example, the inner side of the end of the mounting wing 122 has a boss, and the side of the boss close to the extrusion port 101 is recessed in the direction away from the extrusion port 101 to form a limiting groove 133 with an opening 1331. The end of the scraper 12 can move into the limiting groove 133 through the opening 1331, so that the end is limited in the limiting groove 133, thereby improving the ease of installation of the scraper 12.

[0195] In one alternative embodiment, a limiting groove 133 is provided on one of the mounting wing 112 and the fixed wing 132, and the other of the mounting wing 112 and the fixed wing 132 is provided with a first limiting part 134; when the front housing 13 is covered on the rear housing 11, the first limiting part 134 blocks the opening 1331 of the limiting groove 133, so that the end of the scraping member 12 is limited in the limiting groove 133, thereby preventing the scraping member 12 from coming out of the limiting groove 133 during use.

[0196] like Figure 13As shown, the mounting part is a fixed wing 132, that is, a limiting groove 133 is provided on the inner side of the fixed wing 132, and the scraping member 12 is limited in the limiting groove 133 through the opening 1331 of the limiting groove 133. The end of the mounting wing 112 is provided with a first limiting part 134, which can be provided with an arc-shaped structure matching the curvature of the limiting groove 133. When the front shell 13 is covered on the rear shell 11, the fixed wing 132 is limited to the outside of the mounting wing 112, so that the first limiting part 134 provided at the end of the mounting wing 112 abuts against the limiting groove 133 provided on the inner side of the root of the fixed wing 132, so that the first limiting part 134 blocks the opening 1331 of the limiting groove 133. For example, the arc-shaped structure of the first limiting part 134 is provided at the opening 1331 of the limiting groove 133 to prevent the scraping member 12 from coming out of the limiting groove 133.

[0197] Alternatively, the mounting part can be a mounting wing 122. The end face of the mounting wing 122 is recessed in the direction close to the extrusion port 101 to form a limiting groove 133 with an opening 1331. The scraping member 12 is limited and positioned in the limiting groove 133 through the opening 1331. A first limiting part 134 is provided on the inner side of the root of the fixed wing 132. When the front housing 13 is covered on the rear housing 11, the fixed wing 132 is limited and positioned on the outer side of the mounting wing 112. At this time, the first limiting part 134 provided on the inner side of the root of the fixed wing 132 abuts against the end face of the end of the mounting wing 122 and blocks the opening 1331 of the limiting groove 133 provided on the end face of the end of the mounting wing 122. Alternatively, a first limiting part 134 is provided on the end face of the fixed wing 132. When the front housing 13 is covered on the rear housing 11, the end of the fixed wing 132 abuts against the end of the mounting wing 122. That is, the first limiting part 134 provided on the end of the fixed wing 132 can block the opening 1331 of the limiting groove 133 provided on the end of the mounting wing 122.

[0198] In one alternative embodiment, a limiting groove 133 is provided on one of the mounting wing 112 and the fixed wing 132, and the other of the mounting wing 112 and the fixed wing 132 is provided with a snap-fit ​​hole 1125; the second limiting part 135 is provided with a snap-fit ​​shaft 1351. After the front housing 13 is covered on the rear housing 11, the snap-fit ​​shaft 1351 of the second limiting part 135 is inserted into the snap-fit ​​hole 1125, so that the second limiting part 135 is snap-fitted at a position close to the limiting groove 133, sealing the opening 1331 of the limiting groove 133.

[0199] like Figures 13 to 15As shown, the mounting part is a fixed wing 132, with a limiting groove 133 on its inner side. The scraping member 12 is limited in the limiting groove 133 through the opening 1331. The end of the mounting wing 112 is provided with a snap-fit ​​hole 1125. After the front housing 13 is placed on the rear housing 11, the fixed wing 132 is limited and abuts against the outer side of the mounting wing 112, so that the end of the mounting wing 112 is adjacent to the limiting groove 133. At this time, the snap-fit ​​shaft 1351 of the second limiting part 135 can be inserted into the snap-fit ​​hole 1125, so that the second limiting part 135 is snapped in place on the mounting wing 112 near the limiting groove 133, sealing the opening 1331 of the limiting groove 133. Optionally, the end of the mounting wing 112 may be provided with two locking holes 1125 at intervals along the direction in which the mop plate 60 is inserted into the squeezing port 101. The second limiting part 135 is provided with two locking shafts 1351, which engage with the two locking holes 1125 to further fix the second limiting part 135 and prevent the second limiting part 135 from shifting relative to the mounting wing 112, thus affecting the sealing effect on the opening 1331.

[0200] Alternatively, the mounting portion can be a mounting wing 122, with its end face recessed towards the extrusion port 101 to form a limiting groove 133 with an opening 1331. The scraping member 12 is limited and positioned in the limiting groove 133 through the opening 1331. A snap-fit ​​hole 1125 is provided at the root of the fixed wing 132. After the front housing 13 is placed on the rear housing 11, the fixed wing 132 is limited and abuts against the outside of the mounting wing 112, so that the root of the fixed wing 132 is positioned adjacent to the limiting groove 133. At this time, the snap-fit ​​shaft 1351 of the second limiting portion 135 can be inserted into the snap-fit ​​hole 1125, so that the second limiting portion 135 is snapped and positioned on the fixed wing 132 near the limiting groove 133, sealing the opening 1331 of the limiting groove 133. Optionally, the end of the fixed wing 132 may be provided with two locking holes 1125 at intervals along the direction in which the mop plate 60 is inserted into the squeezing port 101, and the second limiting part 135 is provided with two locking shafts 1351. The two locking shafts 1351 are engaged with the two locking holes 1125 to further fix the second limiting part 135 and prevent the second limiting part 135 from displacing relative to the fixed wing 132, which would affect the sealing effect on the opening 1331.

[0201] It should be noted that the first limiting part 134 and the second limiting part 135 can be set at the same time to achieve the effect of strengthening the sealing of the opening 1331 and preventing the scraping part 12 from falling out.

[0202] In one optional embodiment, a positioning protrusion 1352 is provided on the side of the second limiting part 135 away from the limiting groove 133, and a positioning groove 136 is provided on the mounting wing 112 or the fixed wing 132; when the snap-fit ​​shaft 1351 of the second limiting part 135 is inserted into the snap-fit ​​hole 1125, the positioning protrusion 1352 is limited in the positioning groove 136.

[0203] In the above embodiment, by sealing the opening 1331 of the limiting groove 133 with the second limiting part 135, the scraping part 12 can be prevented from falling out of the limiting groove 133 during use. The positioning protrusion 1352 and the positioning groove 136 provide positioning for the installation of the second limiting part 135, preventing ineffective installation due to incorrect installation direction of the second limiting part 135.

[0204] In one alternative implementation, such as Figure 4 As shown, the rear plate 111 is recessed in the direction away from the squeezing port 101 to form a receiving groove 1110 for accommodating the mop handle, so that the wringing mechanism 10 can be slidably connected to the mop handle.

[0205] In one alternative implementation, combined with Figures 1 to 6 As shown, the rear panel 111 is provided with a plurality of elongated drainage holes 102 extending in the direction of the mop blade insertion squeezing port 101. The front cover 131 is provided with a plurality of elongated drainage holes 102 extending in the direction of the mop blade insertion squeezing port 101. The drainage holes 102 allow the wastewater squeezed out of the mop blade to be discharged through the drainage holes 102, preventing it from accumulating in the front housing 13 and the rear housing 11.

[0206] In one alternative implementation, combined with Figure 7 , Figure 7 , Figure 10 As shown, a water passage window 1310 is provided on the front cover plate 131. The water passage window 1310 penetrates the front cover plate 131 and corresponds to the scraper 12, so that the sewage squeezed out by the scraper 12 is discharged through the water passage window 1310.

[0207] In the above embodiment, the water passage window 1310 is a strip-shaped opening opened along the length direction of the front cover plate 131. The water passage window 1310 corresponds to the scraper 12 and can connect the entire scraper 12 with the external space, so that the sewage squeezed out by the scraper 12 can be discharged directly through the water passage window 1310 and will not accumulate in the front housing 13 and the rear housing 11.

[0208] In one alternative embodiment, the mounting wing 112 extends in a direction perpendicular to the rear panel 111. The fixed wing 132 extends in a direction perpendicular to the front cover 131. Alternatively, in other alternative embodiments, the mounting wing 112 may extend outward or inward at an acute or obtuse angle to the rear panel 111. The fixed wing 132 may also extend outward or inward at an acute or obtuse angle to the front cover 131.

[0209] In the above embodiments, the vertical extension of the mounting wing 112 and the fixed wing 132 allows the mounting wing 112 and the fixed wing 132 to abut against each other when the front housing 13 is covered on the rear housing 11, or the fixed wing 132 is limited to abutting against the outside of the mounting wing 112, or the mounting wing 112 is limited to abutting against the outside of the fixed wing 132.

[0210] Secondly, this utility model provides another dewatering mechanism 10, which includes a rear housing 11, a scraping member 12, and a front housing 13.

[0211] Specifically, the rear housing 11 includes a rear plate 111 and mounting wings 112 extending away from the rear plate 111 at both ends. More precisely, the mounting wings 112 extend towards the front housing 13 at both ends of the rear plate 111. The two ends of the scraping member 12 are respectively connected to the mounting wings 112 at both ends of the rear plate 111. The scraping member 12 and the rear housing 11 together form a squeezing opening 101 for inserting the mop board and cleaning the wiping material on the mop board. The scraping member 12 is used to scrape and / or squeeze the wiping material on the mop board. The front housing 13 includes a front cover plate 131 and fixed wings 132 extending from both ends of the front cover plate 131 toward the rear housing 11. The front housing 13 covers the scraper 12 on the side away from the rear plate 111, and the fixed wings 132 are positioned on the outside of the mounting wing 112, which is the side of the mounting wing 112 away from the extrusion port 101.

[0212] In this embodiment, the scraping component 12 is mounted on the two mounting wings 112 provided at both ends of the rear housing 11. The fixed wings 132 provided at both ends of the front housing 13 limit the mounting wings 112, thereby effectively limiting the mounting wings 112 and preventing them from deforming under force and expanding outward, which could cause the scraping component 12 to fall off. This allows the scraping component 12 to provide a stable and effective squeezing force to clean the object being wiped, greatly improving the user experience. It effectively solves the contradiction between the high production cost of the wringing mechanism 10 and the unstable installation of the scraping component 12 in the prior art, reducing production costs while ensuring the product's performance and user experience.

[0213] In the above embodiment, since the root of the mounting wing 112 is connected to the rear plate 111, the structural strength is higher, while the structural strength of the end farther from the rear plate 111 is lower. Additionally, to facilitate connection with the subsequent fastening member 14, in this embodiment, preferably, the two fixing wings 132 are positioned on the outer sides of the ends of the two mounting wings 112, thereby effectively preventing the ends of the two mounting wings 112 from expanding outwards and causing the scraping member 12 to detach.

[0214] It should be noted that in this embodiment, the fixed wing 132 and the mounting wing 112 can be directly connected and fixed, such as by snap-fitting or bonding, or they can be further reinforced with the help of connectors. Of course, in other alternative embodiments, the fixed wing 132 may not be connected to the mounting wing 112, but may directly abut against the outside of the mounting wing 112 to limit the mounting wing 112.

[0215] In some embodiments, the squeezing mechanism 10 further includes a fastening member 14; an assembly portion is formed by combining the outer sides of the mounting wing 112 and the fixed wing 132 away from the squeezing port 101, and the fastening member 14 is installed in conjunction with the assembly portion to connect the rear housing 11 and the front housing 13. Specifically, the assembly portion is formed by combining the outer sides of the mounting wing 112 and the fixed wing 132, and the fastening member 14 is provided on the outer side of the mounting wing 112 and the fixed wing 132, that is, on the side of the mounting wing 112 and the fixed wing 132 away from the squeezing port 101, and is installed in conjunction with the assembly portion. The fastening member 14 can further strengthen the connection between the mounting wing 112 and the fixed wing 132, and can also limit and prevent the mounting wing 112 and the fixed wing 132 from deforming, providing dual protection.

[0216] In the above embodiments, the fastening member 14 can be any shape such as plate, ring or strip, as long as it can cover the outer side of the mounting wing 112 and the fixed wing 132 at the same time, and further fix the mounting wing 112 and the fixed wing 132. The fastening member 14 is fastened to the outer side of the mounting wing 112 and the fixed wing 132, which can further prevent the mounting wing 112 from deforming.

[0217] In some alternative embodiments, the fastener 14 may also be disposed on the side of the mounting wing 112 and the fixing wing 132 near the compression port 101, that is, disposed on the inner side of the mounting wing 112 and the fixing wing 132.

[0218] In some embodiments, the fastener 14 engages with the mounting wing 112 and the fixing wing 132 respectively. By engaging with the mounting wing 112 and the fixing wing 132 respectively, the fastener 14 achieves effective fixation while making assembly and disassembly more convenient and quick.

[0219] In some more specific embodiments, such as Figure 6 , Figure 9 , Figure 10 As shown, the mounting wing 112 is provided with a first mounting hole 1121, and the fixed wing 132 is provided with a second mounting hole 1321. During assembly, the first mounting hole 1121 and the second mounting hole 1321 are aligned. The fastening member 14 is provided with a snap-fit ​​post 141. When the fastening member 14 covers the outside of the mounting wing 112 and the fixed wing 132, the snap-fit ​​post 141 extends into the aligned first mounting hole 1121 and the second mounting hole 1321, and snaps into the first mounting hole 1121 and the second mounting hole 1321 respectively.

[0220] In the above embodiment, by engaging the snap-fit ​​post 141 with the first mounting hole 1121 and the second mounting hole 1321, not only can the mounting wing 112 and the fixed wing 132 be effectively limited in the axial direction, but the mounting wing 112 and the fixed wing 132 are also prevented from rotating, making the connection between the fastener 14, the mounting wing 112 and the fixed wing 132 more reliable and stable.

[0221] Specifically, in this embodiment, the fixed wing 132 has an overlapping area that overlaps the outer side of the end of the mounting wing 112. The mounting wing 112 has a corresponding mating area that overlaps with the overlapping area. The first mounting hole 1121 is opened in the mating area, and the second mounting hole 1321 is opened in the overlapping area. During assembly, the overlapping area of ​​the fixed wing 132 is placed on the outside of the mating area. Then, the first mounting hole 1121 and the second mounting hole 1321 are aligned. Then, the snap-fit ​​pin 141 of the fastener 14 is sequentially inserted into the second mounting hole 1321 and the first mounting hole 1121, and snapped into the second mounting hole 1321 and the first mounting hole 1121 respectively, thereby realizing the connection between the fixed wing 132 and the mounting wing 112.

[0222] In some embodiments, the snap-fit ​​post 141 can be interference-fitted into the first mounting hole 1121 and the second mounting hole 1321 to connect the fastener 14, the fixing wing 132, and the mounting wing 112. Alternatively, deformable claws or snap-fit ​​bosses can be provided on the outer periphery of the snap-fit ​​post 141 to achieve snap-fit ​​fixation between the snap-fit ​​post 141 and the fixing wing 132 and the mounting wing 112.

[0223] In some preferred embodiments, the end of the snap-fit ​​post 141 is provided with an elastic buckle 1411. When the snap-fit ​​post 141 is inserted into the first mounting hole 1121 and the second mounting hole 1321, the elastic buckle 1411 closes. When the end of the snap-fit ​​post 141 passes through the first mounting hole 1121 and the second mounting hole 1321, the elastic buckle 1411 opens to achieve fixation.

[0224] In the above embodiment, the elastic buckle 1411 provided at the end of the snap-fit ​​post 141 has a closed contracted state and an open snap-fit ​​state. When the snap-fit ​​post 141 is inserted into the first mounting hole 1121 and the second mounting hole 1321, the elastic buckle 1411 is in the closed contracted state to facilitate the insertion and engagement of the snap-fit ​​post 141 with the first mounting hole 1121 and the second mounting hole 1321. When the snap-fit ​​post 141 passes through the first mounting hole 1121 and the second mounting hole 1321, the elastic buckle 1411 expands outward to the snap-fit ​​state under its own elastic force and is limited to the inner side of the mounting wing 112, thereby achieving effective fixation of the fastener 14, the fixing wing 132, and the mounting wing 112.

[0225] In some embodiments, such as Figure 6 , Figure 9 , Figure 10 As shown, the mounting wing 112 has two first mounting holes 1121 spaced apart along the insertion direction of the mop plate in the squeezing port 101, and the fixing wing 132 has two second mounting holes 1321 spaced apart along the insertion direction. During assembly, the two first mounting holes 1121 and the two second mounting holes 1321 are aligned to form two aligned hole positions 103. The fastener 14 is provided with two snap-fit ​​pins 141, which are inserted into the two aligned hole positions 103 and snapped together.

[0226] In the above embodiments, the two first mounting holes 1121 and two second mounting holes 1321, as well as the two snap-fit ​​posts 141, which are arranged at intervals, can further improve the stability of the fastener 14 in conjunction with the fixed wing 132 and the mounting wing 112.

[0227] Specifically, two first mounting holes 1121 are spaced apart at both ends of the mounting wing 112 along the insertion direction of the mop 200, and two second mounting holes 1321 are spaced apart at both ends of the fixed wing 132 along the insertion direction of the mop 200. Correspondingly, two snap-fit ​​pins 141 are spaced apart at both ends of the fastener 14 along the insertion direction of the mop 200. Through the cooperation of the two sets of alignment holes 103 and snap-fit ​​pins 141, it can be effectively ensured that the mounting wing 112 can maintain strong anti-deformation ability throughout the entire process of inserting the mop 200 into the squeezing port 101.

[0228] In an optional embodiment, the fastener 14 can also be embedded in the mounting groove, that is, the shape of the mounting groove matches the fastener 14, so that the fastener 14 can be precisely embedded in the mounting groove. This can prevent the fastener 14 from coming out of the mounting groove when subjected to external force, that is, prevent the edges of the fastener 14 from lifting up when subjected to collisions or force from external objects, which would cause the fastener 14 to come out of the mounting groove, thereby improving the stability of the dewatering mechanism installation.

[0229] In one optional embodiment, a portion of the mounting groove is provided on the outer side of the mounting wing 112, and another portion of the mounting groove is provided on the outer side of the fixed wing 132; after the fixed wing 132 is positioned and abuts against the outer side of the mounting wing 112, they are spliced ​​together to form a complete mounting groove.

[0230] For example, when the scraper 12 is provided on the mounting wing 112, most of the mounting groove is provided on the fixed wing 132 and a small part is provided on the mounting wing 112. After the fixed wing 132 is limited and abuts against the outside of the mounting wing 112, the complete mounting groove is formed.

[0231] The mounting wing 112 and the fixed wing 132 are combined to form a mounting groove. When the fastener is placed on the outside of the mounting wing 112 and the fixed wing 132, it is engaged in the mounting groove, which can further improve the stability of the engagement between the mounting wing 112 and the fixed wing 132 and strengthen the connection between the fastener 14, the mounting wing 112 and the fixed wing 132.

[0232] In one alternative implementation, such as Figure 6 As shown, the outer periphery of the mounting wing 112 is provided with a first flange 1122, which forms part of the outer wall of the mounting groove; the outer periphery of the fixed wing 132 is provided with a second flange 1323, which forms another part of the outer wall of the mounting groove. Through this design, when the fastener 14 is closed on the outer sides of the mounting wing 112 and the fixed wing 132, the outer periphery of the fastener 14 can abut against the flanges of the outer periphery of the mounting wing 112 and the fixed wing 132 respectively, further strengthening the connection between the fastener 14, the mounting wing 112, and the fixed wing 132. At the same time, it also avoids the problem of the outer periphery of the fastener 14 easily lifting up and affecting aesthetics.

[0233] In some embodiments, the fixed wing 132 engages with the mounting wing 112.

[0234] In the above embodiments, when assembling the front housing 13 and the rear housing 11, the fixed wing 132 is first snapped into the mounting wing 112 to pre-fix them before being fixed by the fastener 14. This can further improve the stability of the engagement between the fixed wing 132 and the mounting wing 112, reduce the risk of deformation of the mounting wing 112, and effectively avoid the problem that the first mounting hole 1121 and the second mounting hole 1321 are not easy to align or that the fixed wing 132 and the mounting wing 112 are easy to slide, which makes it difficult to fix the fastener 14.

[0235] In some embodiments, the fixed wing 132 is engaged with the end of the mounting wing 112 away from the rear plate 111. Optionally, the fixed wing 132 and the mounting wing 112 are engaged and fixed by a engaging protrusion 1123 and a engaging groove 1324; wherein, one of the engaging protrusion 1123 and the engaging groove 1324 is located at the free end of the mounting wing 112, which is the end of the mounting wing 112 away from the rear plate 111; the other of the engaging protrusion 1123 and the engaging groove 1324 is located at the rear root of the fixed wing 132, which is the end of the fixed wing 132 near the front cover plate 131.

[0236] It should be noted that in this embodiment, the fixed wing 132 and the mounting wing 112 are not limited to being fixed by snap-fit ​​protrusion 1123 and snap-fit ​​groove 1324, but can also be fixed by snap-fit ​​structures such as claws, buckles, and snap-fit ​​bosses.

[0237] In the above embodiment, the mounting wing 112 is snapped onto the rear root of the fixed wing 132. Compared with snapping onto the free end of the fixed wing 132, this makes the connection between the fixed wing 132 and the mounting wing 112 more secure and stable.

[0238] Specifically, in this embodiment, the mounting wing 112 includes a mounting wing 112 body connected to the rear plate 111 and an extension 1120 mounted on the end of the wing body. A snap-fit ​​protrusion 1123 is provided on the outer wall surface of the extension 1120, and a snap-fit ​​groove 1324 is provided on the rear root of the fixed wing 132. The extension 1120 can extend into the rear root of the fixed wing 132 and snap-fit ​​with the snap-fit ​​groove 1324. Optionally, the extension 1120 is a protruding plate protruding from the middle of the mounting wing 112 body.

[0239] In some embodiments, the scraping member 12 has a connecting end adapted to connect with the mounting wing 112; in one embodiment, the mounting wing 112 has a snap-fit ​​protrusion 1123, the fixed wing 132 has a snap-fit ​​groove 1324, and the connecting end is located between the snap-fit ​​protrusion 1123 on the mounting wing 112 and the rear plate 111. Alternatively, in another embodiment, the mounting wing 112 has a snap-fit ​​groove 1324, the fixed wing 132 has a snap-fit ​​protrusion 1123, and the connecting end is located between the snap-fit ​​groove 13243 on the mounting wing 112 and the rear plate 111.

[0240] In the above embodiment, the root of the mounting wing 112 is connected and fixed to the rear plate 111, and the end of the mounting wing 112 away from the rear plate 111 is snapped and fixed to the fixed wing 132. The scraping member 12 is disposed between the root of the mounting wing 112 and the snapping position between the mounting wing 112 and the fixed wing 132, thereby enabling more stable and reliable support and limiting from both sides of the force point where the scraping member 12 is connected to the mounting wing 112, effectively preventing the scraping member from squeezing the mounting wing 112 under force, causing the two mounting wings 112 to move away from each other and deform.

[0241] In some embodiments, one of the mounting wing 112 and the scraper 12 is provided with a groove 1124, and the other is provided with a guide block 121. The guide block 121 is disposed in the groove 1124 and slides along the groove 1124.

[0242] In some preferred embodiments, the groove 1124 is formed on the extension 1120, and the extension 1120 is detachably connected and fixed to the mounting wing 112 body. This design facilitates the assembly and disassembly of the scraping component 12.

[0243] Even better, such as Figure 10 As shown, the groove 1124 is an inclined groove formed on the extension 1120.

[0244] In some embodiments, guide blocks 121 are provided at both ends of the scraping member 12, and sliding grooves 1124 are provided on both sides of the mounting wings 112 of the rear plate 111.

[0245] In some embodiments, the groove 1124 is inclined along the direction of the mop plate insertion squeezing port 101, and the distance between it and the rear plate 111 gradually decreases. By setting the groove 1124 as an inclined groove, as the mop 200 is inserted, it will drive the scraping member 12 to slide in the groove 1124, and the squeezing port 101 will become smaller and smaller, thereby improving the squeezing effect.

[0246] In some embodiments, such as Figures 5 to 7 as well as Figure 10 As shown, a covering protrusion 1322 is provided on the side of the fixed wing 132 away from the front cover plate 131, and the covering protrusion 1322 covers the outside of the area of ​​the mounting wing 112 where the scraper 12 is provided.

[0247] In the above embodiment, by providing a covering protrusion 1322 to cover the outer side of the area on the mounting wing 112 where the scraper 12 is provided, the fixed wing 132 can avoid the scraper 12 and the mounting structure on the mounting wing 112 used to mount the scraper 12. This effectively prevents the scraper 12 or the mounting structure on the mounting wing 112 from being exposed and interfering with the fixed wing 132, thus affecting the normal movement of the scraper 12 within the extrusion port 101. For example, it can prevent interference with the rotation, swinging, or sliding of the scraper 12.

[0248] In some specific embodiments, the covering protrusion 1322 is a structure in which the fixed wing 132 is recessed outward and pressed into shape.

[0249] In one alternative embodiment, a limiting groove 133 is provided on the inner side of the mounting wing 112, and an opening 1331 is provided on the side of the limiting groove 133 near the extrusion port 101; the end of the scraping member 12 is installed into the limiting groove 133 through the opening 1331.

[0250] For example, the limiting groove 133 can be provided at the end of the mounting wing 122. For instance, the end face of the mounting wing 122 is recessed in the direction near the extrusion port 101 to form a limiting groove 133 with an opening 1331. Alternatively, the limiting groove 133 can be provided on the inner side of the mounting wing 122. For example, the inner side of the end of the mounting wing 122 has a boss, and the side of the boss near the extrusion port 101 is recessed in the direction away from the extrusion port 101 to form a limiting groove 133 with an opening 1331. The end of the scraper 12 can move into the limiting groove 133 through the opening 1331, so that the end is limited in the limiting groove 133, improving the ease of installation of the scraper 12.

[0251] In one optional embodiment, the mounting wing 112 is provided with a snap-fit ​​hole, which can be located on the side of the limiting groove 133 near the extrusion port 101; the second limiting part 135 is provided with a snap-fit ​​shaft 1351, and the end of the scraping member 12 is installed into the limiting groove 133 through the opening 1331. The snap-fit ​​shaft 1351 of the second limiting part 135 is inserted into the snap-fit ​​hole, so that the second limiting part 135 is snap-fitted at a position near the limiting groove 133, sealing the opening 1331 of the limiting groove 133.

[0252] For example, the snap-fit ​​shaft 1351 of the second limiting part 135 is inserted into the snap-fit ​​hole provided on the mounting wing 112, so that the second limiting part 135 is snapped into position on the mounting wing 112 near the limiting groove 133, thereby sealing the opening 1331 of the limiting groove 133. This prevents the scraping part 12 from coming out of the limiting groove 133 due to excessive force when cleaning the wiping material on the mop board. Optionally, the mounting wing 112 may be provided with two snap-fit ​​holes spaced apart along the direction of the mop board 60 insertion squeezing port 101, and the second limiting part 135 is provided with two snap-fit ​​shafts 1351. The two snap-fit ​​shafts 1351 are snapped into the two snap-fit ​​holes, which can further fix the second limiting part 135 and prevent the second limiting part 135 from displacing relative to the mounting wing 112, thus affecting the sealing effect of the opening 1331.

[0253] In some embodiments, the rear plate 111 is recessed in a direction away from the extrusion port 101 to form a receiving groove 1110 for accommodating the mop handle, so that the wringing mechanism 10 is slidably connected to the mop handle.

[0254] In some embodiments, combined with Figures 1 to 6 As shown, the rear panel 111 is provided with multiple drainage holes 102. The drainage holes 102 allow the wastewater squeezed out of the mop blade to be discharged through the drainage holes 102, preventing it from accumulating in the front housing 13 and the rear housing 11.

[0255] In some embodiments, combined with Figures 1 to 6 As shown, the front cover plate 131 is provided with a plurality of drainage holes 102. The drainage holes 102 allow the wastewater squeezed out of the mop blade to be discharged through the drainage holes 102, preventing it from accumulating in the front housing 13 and the rear housing 11.

[0256] In some alternative implementations, combined with Figure 7 , Figure 10 As shown, a water passage window 1310 is provided on the front cover plate 131. The water passage window 1310 penetrates the front cover plate 131 and corresponds to the scraper 12, so that the sewage squeezed out by the scraper 12 is discharged through the water passage window 1310.

[0257] In the above embodiment, the water passage window 1310 is a strip-shaped opening opened along the length direction of the front cover plate 131. The water passage window 1310 corresponds to the scraper 12. The sewage squeezed out by the scraper 12 can be directly discharged through the water passage window 1310 and will not accumulate in the front housing 13 and the rear housing 11.

[0258] In some embodiments, the mounting wing 112 extends in a direction perpendicular to the rear plate 111. Of course, in other alternative embodiments, the mounting wing 112 may also extend outward or inward at an angle.

[0259] In some embodiments, the fixed wing 132 extends in a direction perpendicular to the front cover 131. Of course, in other alternative embodiments, the fixed wing 132 may also extend outward or inward at an angle.

[0260] In this embodiment, after the front housing 13 and the rear housing 11 are engaged, there is an overlapping area between the mounting wing 112 and the fixed wing 132. By engaging the fastener 14 with the overlapping area, the front housing 13 and the rear housing 11 can be fixed, and the fixation is relatively stable and reliable, so that the front housing 13 and the rear housing 11 are not easy to separate.

[0261] In some embodiments, an extrusion member 50113 is provided on the side of the rear housing 11 opposite to the scraping member 12, and the extrusion member 50113 cooperates with the scraping member 12 to form an extrusion port 101.

[0262] Preferably, the extrusion part 50113 is an extrusion roller.

[0263] Preferably, two sets of extrusion members 50113 are spaced apart on the rear housing 11 along the length direction of the extrusion port 101. More preferably, each set of extrusion members 50113 includes two extrusion rollers spaced apart along the length direction of the mop blade.

[0264] The structure of the scraping component 12 in this embodiment will be briefly described below with reference to the accompanying drawings.

[0265] In one implementation, combined with Figures 1 to 6 As shown, the scraping component 12 may include multiple scrapers, rollers, and / or scrapers. Optionally, the multiple scrapers, rollers, and scrapers may be arranged sequentially along the insertion direction of the mop board. The mounting wing 112 is provided with shaft holes suitable for mounting the scraping component 12, and both ends of the scraping component 12 are provided with rotating shafts suitable for rotatably connecting in the shaft holes; or, guide blocks 121 are fixedly provided at both ends of the scraping component 12, and the guide blocks 121 are slidably connected in the sliding grooves 1124 of the mounting wing 112.

[0266] Furthermore, combined Figure 4 , Figure 6 and Figure 11 As shown, the scraper 12 has several guide grooves 122 on one side near the front housing 13. The guide grooves 122 are arranged at intervals along the length of the scraper. The inner wall of the front housing 13 has several guide ribs 1311. During assembly, the guide grooves 122 and guide ribs 1311 work together to guide the scraper and prevent jamming caused by different sliding distances at both ends during the sliding process.

[0267] In another implementation, combined Figure 1 , Figures 7 to 10As shown, the scraping component 12 includes a mounting frame and a scraping section disposed within the mounting frame. The scraping component 12 includes a scraper located in the middle and multiple rollers distributed on both sides of the scraper along the insertion direction of the mop blade. The multiple rollers are arranged in an arc shape on both sides of the scraper, and the scraping section is arranged in an arc shape on the side facing the extrusion port 101. The two ends of the scraping component 12 can be fixedly connected to the mounting wing 112, or the two ends of the mounting frame of the scraping component 12 can be respectively fixedly provided with guide blocks 121 in the slide groove 1124 suitable for sliding connection on the mounting wing 112. That is, the two ends of the scraping component 12 can be slidably connected to the mounting wing 112 through the slide groove 1124 and the guide block 121.

[0268] This embodiment also provides a mop 200, including a mop handle, a mop board, and a wringer head 100. The wringer head 100 is sleeved on the mop handle, and a wringing mechanism 10 of any of the above embodiments is provided at one end near the mop board. The mop board can rotate relative to the mop handle between a use position and a cleaning position. When the wringer head 100 moves along the mop handle, the mop board moves in the squeezing port 101 to clean the wiping material on the mop board located in the cleaning position.

[0269] In some embodiments, the wringer head 100 further includes a gripping portion 40 and a connecting portion, wherein the gripping portion 40 is connected to the wringing mechanism 10 via the connecting portion.

[0270] Specifically, the grip 40 is a handle fixedly mounted on the upper part of the rear housing 11 via a connecting part. The grip 40 facilitates the user's operation of wringing out water. A groove 1124 is formed inside the grip handle, through which the mop handle can pass and slide. In use, the mop plate is inserted into the squeezing port 101 of the wringing mechanism 10, and the mop handle is inserted into the grip 40. The user holds the grip 40 with one hand to fix the position of the wringing head 100, and holds the end of the mop handle with the other hand, sliding and pulling the mop handle back and forth to drive the mop plate to move back and forth in the port, thereby wringing out water and cleaning the wiping material on the mop plate.

[0271] In some embodiments, the connecting portion includes an arc-shaped plate that partially encloses the mop handle. The arc-shaped plate is fixed to the outer peripheral wall of the receiving groove 1110 of the rear plate 111 and partially encloses the mop handle, thereby achieving the connection and fixation between the grip portion 40 and the wringing mechanism 10.

[0272] In some embodiments, such as Figure 1 and Figure 2 As shown, the connecting part includes multiple connecting rods 30 arranged around the mop handle. The connection between the grip part 40 and the wringing mechanism 10 is achieved by the multiple connecting rods 30 arranged around the outer periphery of the mop handle, making it more convenient for the user to hold.

[0273] Optionally, there are two connecting rods 30, which can be spaced apart on both sides of the receiving groove 1110 of the rear housing 11.

[0274] In some embodiments, such as Figure 16 As shown, the end of the grip 40 near the mop plate is provided with a mating hole 41, and the end of the connecting rod 30 is inserted into the mating hole 41. For example, the connecting rod 30 can be interference-fitted with the mating hole 41, thereby fixing the connecting rod 30 to the grip 40; or the end of the connecting rod 30 is provided with a snap-fit ​​structure that prevents it from coming out, and the interior of the mating hole 41 is provided with a snap-fit ​​boss. After the connecting rod 30 is inserted into the mating hole, the snap-fit ​​structure that prevents it from coming out of the mating hole engages with the snap-fit ​​boss to prevent the connecting rod 30 from coming out of the mating hole.

[0275] In some embodiments, such as Figure 17 As shown, the gripping part 40 is provided with an open groove 42. The bottom of the open groove 42 is connected to the mating hole 41 through a through hole 421. The end of the connecting rod 30 is connected to the gripping part 40 through a fastener inserted into the through hole 421.

[0276] For example, after the end of the connecting rod 30 is inserted into the mating hole 41, its end corresponds to the through hole 421. The user can insert a fastener into the through hole 421 through the open slot 42, and fix the connecting rod 30 to the grip part 40 by the fastener. The fastener can be a screw. For example, the connecting rod 30 can be a hollow structure. After the end of the connecting rod 30 is inserted into the mating hole 41, its hollow part corresponds to the through hole 421. The fastener inserted into the through hole 421 can be rotated into the hollow part of the connecting rod 30 to achieve a fixed connection between the connecting rod 30 and the grip part 40. Alternatively, the fastener can also be a rivet, pin, or self-tapping screw, etc.

[0277] In some embodiments, such as Figure 1 and Figure 17 As shown, a sealing part 422 is provided in the open groove 42. The sealing part 422 is used to seal the open groove 42. The sealing part 422 can be snapped into the open groove 42 or press-fitted. The sealing part 422 can be made of flexible material. For example, the inner wall of the open groove 42 is provided with an annular step, and the outer wall of the sealing part 422 is provided with an annular boss. After the sealing part 422 is installed into the open groove 42, the annular boss abuts against the annular step.

[0278] In the above example, by sealing the opening groove 42 with the sealing part 422, on the one hand, the loosening of the fastener is restricted, and the connecting rod 30 is prevented from detaching from the grip part 40; on the other hand, the connection area of ​​the fastener is also protected, and the accumulated dirt is prevented from making the fastener impossible to remove.

[0279] In some embodiments, a positioning element 20 is provided on the mop handle, and multiple connecting rods 30 pass through the positioning element 20, with one end connected to the grip portion 40 and the other end connected to the wringing mechanism 10. The positioning element 20 prevents the connecting rods 30 from twisting around the mop handle, thus preventing the grip portion 40 from moving the wringing mechanism 10. Simultaneously, the positioning element 20 can also lock the wringing mechanism 10; that is, when the grip portion 40 moves the wringing mechanism 10 to abut against the positioning element 20, the positioning element 20 can engage with the wringing mechanism 10, locking the wringing mechanism 10 to the positioning element 20 and preventing the wringing mechanism 10 from falling onto the mop board 60 and damaging it during normal use.

[0280] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
