Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, and in particular to a scraping component, a wringer, and a wringing mop. Background Technology

[0002] When washing a mop, the scraper installed on the mop wringer can remove excess liquid from the mop board, achieving quick cleaning of the mop board.

[0003] In related technologies, the scraper is usually mounted directly on the wringer. However, due to the sharp edges of the scraper, it is easy to damage the wringer when it moves under the influence of the mop blade, thus affecting the lifespan of the mop. Utility Model Content

[0004] This utility model provides a scraping component, a wringer, and a wringer mop to solve the defect in related technologies where the scraping component damages the wringer.

[0005] In a first aspect, this utility model provides a scraping assembly for mounting to a wringer with a squeezing nozzle and for cleaning the wiping material from a mop board; the scraping assembly includes:

[0006] The housing has a recessed cavity;

[0007] A scraper, the scraper being confined within the receiving cavity, the sidewalls of the receiving cavity surrounding the edge of the scraper such that the edge is isolated from external objects.

[0008] Beneficial effects: In this embodiment, the scraper is confined within the housing cavity, and the sidewall of the cavity surrounds the edge of the scraper, isolating the edge of the scraper from external objects. This prevents the scraper from damaging external objects due to its sharp edge when cleaning the mop board. Especially when the scraper assembly is installed on the wringer, the sidewall of the cavity surrounds the edge of the scraper, ensuring that even if there is relative movement between the scraper and the wringer under the action of the mop board, the edge of the scraper will not damage the wringer, thus improving the service life of the wringer.

[0009] According to the present invention, a scraping component is fixed in the receiving cavity by hot-melt head.

[0010] Beneficial effects: In this embodiment of the application, the scraper is fixed in the receiving cavity by heat fusion head, which eliminates the need for other fixing methods such as threaded connection or welding to fix the scraper, thus reducing labor and material costs; moreover, the heat fusion connection method by heat fusion head is simple to operate and takes less time, which simplifies the process of fixing the scraper in the receiving cavity and improves work efficiency.

[0011] According to the present invention, a scraping component is provided with an insertion hole in the area near the edge of the scraping component, and a hot melt head adapted to the insertion hole is provided on the bottom wall of the receiving cavity; after the hot melt head is heated and melted, it forms a limiting part, which is used to fix the scraping component in the receiving cavity.

[0012] Beneficial effects: In the embodiments of this application, an insertion hole is provided in the area near the edge of the scraper, and a hot melt head adapted to the insertion hole is provided on the bottom wall of the receiving cavity. This allows the limiting part formed after the hot melt head melts to be as far away from the scraping end of the scraper as possible, thus avoiding the limiting part from affecting the scraping effect of the scraper.

[0013] Furthermore, by providing an insertion hole near the edge of the scraper, a hot-melt head provided on the bottom wall of the receiving cavity extends from the insertion hole. After the hot-melt head is heated and melted, it forms a limiting part, preventing the limiting part from detaching from the insertion hole of the scraper. Thus, the combined effect of the insertion hole and the limiting part increases the firmness of the scraper fixed within the receiving cavity. Moreover, because the hot-melt head re-solidifies after heating and melting, a strong bond is formed between molecules, making the fixing strength of the limiting part higher than other connection methods, ensuring the stability and durability of the scraper fixed within the receiving cavity.

[0014] According to the present invention, a scraping component is provided with a protrusion on the edge of the insertion hole, and at least a portion of the insertion hole is formed in the protrusion; an arc-shaped relief groove is provided in the area of ​​the side wall of the receiving cavity opposite to the hot melt head; when the scraping component is disposed in the receiving cavity, the protrusion is accommodated in the arc-shaped relief groove.

[0015] Beneficial effects: In the embodiments of this application, since a protrusion is provided on the edge of the socket and the protrusion can be accommodated in the arc-shaped relief groove, the relative position of the socket and the hot melt head can be quickly positioned with the positioning assistance of the arc-shaped relief groove during the process of setting the scraper in the receiving cavity, making it easier and faster for the hot melt head to extend out of the socket, thus improving the setting efficiency of the scraper.

[0016] Furthermore, when the scraper is placed in the receiving cavity, the sidewall of the arc-shaped relief groove wraps around the protrusion, so that the arc-shaped relief groove further limits the scraper. Under the combined action of the protrusion and the arc-shaped relief groove, the scraper is prevented from shifting in the receiving cavity, thus enhancing the stability of the scraper in the receiving cavity.

[0017] According to the present invention, a scraping component is provided with a plurality of insertion holes in the area near the two oppositely arranged long edges of the scraping component, and a plurality of hot melt heads adapted to the insertion holes are provided on the two opposite long edges of the bottom wall of the receiving cavity.

[0018] Beneficial effects: In this embodiment, by providing multiple heat-sealing heads that are adapted to the sockets, multiple limiting parts can be formed to fix the scraper, further enhancing the firmness of the scraper within the receiving cavity. Furthermore, even if a heat-sealing head or socket is damaged, other heat-sealing heads or sockets can still limit the scraper, ensuring the reliability and stability of the scraper fixed within the receiving cavity.

[0019] According to the present invention, a scraping assembly is provided, the scraping assembly further comprising a clip plate;

[0020] The buckle plate is disposed on the side of the scraper away from the housing and is engaged with the housing so that the scraper is confined between the receiving cavity and the buckle plate.

[0021] Beneficial effects: In this embodiment of the application, by snapping the buckle plate to the housing, the scraper is limited to the receiving cavity and the buckle plate, thereby further limiting the scraper and making the scraper more firmly fixed in the receiving cavity; furthermore, when using the hot melt head to fix the scraper, the buckle plate is set on the side of the scraper away from the housing, which can protect the limiting part formed after the hot melt head is heated and melted, and avoid damage to the limiting part.

[0022] Furthermore, in some possible implementations, even when the scraper does not have a hot melt head or the limiting part formed after the hot melt head is heated and melted is damaged, the buckle can still limit the scraper between the receiving cavity and the buckle, so that the scraper assembly can still clean the mop board and ensure the reliability of the scraper assembly.

[0023] According to the present invention, a scraping component is provided with a hook on one of the buckle plates and a groove on the inner wall of the receiving cavity. The hook and the groove are engaged and fastened, so that the scraping component is limited to the receiving cavity and the buckle plate.

[0024] Beneficial effects: In the embodiments of this application, the hook and slot structure is simple and has low manufacturing cost. Furthermore, the snap-fit ​​method of the hook and slot makes installation and disassembly very easy. Therefore, the buckle plate and the inner wall of the receiving cavity can be easily and quickly snapped together through the hook and slot, thereby enabling the scraping part to be quickly and firmly confined between the receiving cavity and the buckle plate.

[0025] According to the present invention, a scraping assembly is provided in which the edge of the buckle plate extends toward the housing and is provided with the buckle hook, and the bottom wall of the receiving cavity is provided with the buckle groove near the side wall.

[0026] Beneficial effects: In this embodiment, the buckle plate is easier to replace than the housing. Furthermore, the buckle hook is more prone to damage than the buckle groove. Therefore, by providing a buckle hook on the buckle plate and a buckle groove in the receiving cavity, only the buckle plate needs to be replaced if the buckle hook is damaged, reducing labor and material costs.

[0027] According to the present invention, a scraping component is provided with a recessed edge on the scraping member, which is provided with a relief groove corresponding to the hook and the groove; the hook passes through the relief groove and engages with the groove, so that the scraping member is limited to the receiving cavity and the buckle plate.

[0028] Beneficial effects: In this embodiment of the application, by setting a relief groove corresponding to the hook and the groove in the edge of the scraper, the hook of the buckle plate can pass smoothly through the edge of the scraper, saving the space occupied.

[0029] Furthermore, the hook passes through the relief groove, which restricts the displacement of the scraper under the combined action of the hook and the relief groove, thereby making the scraper more firmly confined between the receiving cavity and the buckle plate.

[0030] According to the present invention, a wiping assembly is provided with a positioning post in the area near the edge of the bottom wall of the receiving cavity, and a positioning hole is provided in the area near the edge of the wiping member. When the wiping member is placed in the receiving cavity, the positioning post is inserted into the positioning hole to position the wiping member in the receiving cavity.

[0031] Beneficial effects: In this embodiment of the application, by setting a positioning post in the area near the edge of the bottom wall of the receiving cavity and setting a positioning hole in the area near the edge of the scraper, the positioning post is inserted into the positioning hole when the scraper is installed by the buckle plate, so as to achieve the positioning function and position the scraper in the receiving cavity.

[0032] According to the present invention, a scraping assembly is provided in which a positioning groove is provided in the area near the edge of the side of the buckle plate close to the housing, and when the buckle plate is engaged with the housing, the end of the positioning post is inserted into the positioning groove.

[0033] Beneficial effects: In this embodiment, when the buckle plate and the housing are engaged, the end of the positioning post is inserted into the positioning groove to position the buckle plate and the housing, making it easier to engage the buckle plate and the housing. Furthermore, inserting the end of the positioning post into the positioning groove makes the connection between the buckle plate and the housing more secure and less prone to detachment.

[0034] According to the present invention, a scraping assembly is provided in which an arc-shaped groove is provided on the side wall of the receiving cavity corresponding to the positioning post, and an arc-shaped protrusion is provided on the edge of the buckle plate.

[0035] When the buckle plate is engaged with the housing, the arc-shaped protrusion is accommodated in the arc-shaped groove on the side wall of the receiving cavity.

[0036] Beneficial effects: In this embodiment of the application, since an arc-shaped protrusion is provided on the edge of the buckle plate and the arc-shaped protrusion is accommodated in the arc-shaped groove on the side wall of the accommodating cavity, the relative position of the buckle plate and the accommodating cavity can be quickly positioned with the positioning assistance of the arc-shaped groove during the buckle plate and the housing, making it easier and faster to snap the buckle plate into the housing and improving the installation efficiency of the buckle plate.

[0037] Furthermore, when the buckle is snapped into the housing, the arc-shaped protrusion is accommodated in the arc-shaped groove on the side wall of the receiving cavity, which saves external space and allows the side wall of the arc-shaped groove to wrap around the arc-shaped protrusion, further limiting the buckle. Under the combined action of the arc-shaped groove and the arc-shaped protrusion, displacement of the buckle is prevented after it is snapped into the housing, thus enhancing the firmness of the buckle being snapped into the housing.

[0038] According to the present invention, a scraping component is provided with a scraping end, and a buckle is provided with a window. The scraping end extends through the window to the side of the buckle away from the housing so as to abut against the wiping material of the mop board.

[0039] Beneficial effects: In this embodiment of the application, by setting a window in the buckle plate, the buckle plate can limit the scraping part between the receiving cavity and the buckle plate, while not preventing the scraping end of the scraping part from extending through the window to the side of the buckle plate away from the housing, so as to facilitate the cleaning of the mop board.

[0040] Furthermore, the swiping end extends through a window to the side of the buckle away from the housing, allowing users to observe the condition of the swiping end through the window, such as the degree of wear on the swiping end and whether there is any residue on the swiping end, thus improving the user experience.

[0041] According to the present invention, a scraping assembly is provided with a hollow window on the bottom wall of the receiving cavity, and at least a portion of the scraping member is exposed through the hollow window.

[0042] Beneficial effects: In this embodiment, by providing a hollow viewing window in the bottom wall of the receiving cavity, the user can directly observe the exposed part of the squeegee within the hollow viewing window, thus facilitating the user's identification of the type of squeegee, such as a squeegee for wiping water, a squeegee for cleaning dirt, or a squeegee for removing hair. Furthermore, the user can directly observe the usage status of the squeegee through the hollow viewing window, such as whether the squeegee is damaged or has shifted within the receiving cavity, allowing the user to take appropriate measures in different situations, thereby improving the user experience.

[0043] According to the present invention, a scraping assembly is provided, wherein the scraping element is a plate-shaped structure made of metal, and the plate-shaped structure has a protruding scraping end for cleaning the wiping object; the sidewall of the receiving cavity surrounds the edge of the plate-shaped structure.

[0044] Beneficial effects: The metal material can be stainless steel or aluminum alloy. Because the edges of the plate-like structure made of metal are relatively sharp, direct installation onto the wringer would damage it during use. By confining the plate-like structure within the receiving cavity, with the side walls of the cavity surrounding the edges of the plate-like structure, and then installing the scraping component onto the wringer, damage to the wringer can be avoided.

[0045] Secondly, this utility model provides a wringer, comprising:

[0046] The body has a squeezing port for inserting a mop board, and the side wall of the squeezing port is provided with an installation cavity;

[0047] As described in the first aspect, the scraping assembly is detachably assembled into the mounting cavity.

[0048] Beneficial effects: In this embodiment, the scraping component is detachably mounted in the mounting cavity of the wringer, so that only the scraping component needs to be replaced when it is damaged, saving labor and consumable costs. Users can also replace different scraping components in the wringer according to the type of material being wiped on the mop board or the different requirements for the dryness of the material, meeting the user's needs in different scenarios.

[0049] Furthermore, since the scraper in the scraping assembly is confined within the housing cavity, and the edge of the scraper is surrounded by the side wall of the housing cavity, the edge of the scraper is isolated from the wringer, thereby preventing the scraper from damaging the wringer due to its sharp edge when cleaning the mop board, thus extending the service life of the wringer.

[0050] According to the present invention, a wringer rack is provided with an installation port on the side wall of the main body; the scraping assembly is inserted into the installation cavity from the installation port along the width direction of the mop board inserted into the squeezing port, and the mop board is inserted into the squeezing port along its length direction.

[0051] Beneficial effects: In the embodiments of this application, by providing an installation port on the side wall of the body, the scraping component can be inserted into the installation cavity from the installation port along the width direction of the mop board inserted into the squeezing port with less effort and convenience;

[0052] On the other hand, the mop board is inserted into the squeezing port along its length, while the scraping component is inserted into the mounting cavity from a mounting port on the side wall of the main body along the width of the mop board inserted into the squeezing port. That is, the direction in which the scraping component is inserted into the mounting cavity is perpendicular to the direction in which the mop board is inserted into the squeezing port. Through this method, during the process of the mop board being inserted into the squeezing port along its length, the force direction on the scraping component is perpendicular to the installation direction, thus making it less likely for the scraping component to fall out of the mounting cavity of the wringer, improving the user experience.

[0053] According to the present invention, a wringer is provided in which the top wall and / or bottom wall of the mounting cavity are provided with a sliding groove extending along the width direction of the mop board, and the top and / or bottom of the housing in the scraping assembly are respectively provided with a sliding rail extending along the width direction of the mop board.

[0054] When the housing is inserted into the mounting cavity from the mounting port along the width direction of the mop board, the slide rail slides along the slide groove until the end of the housing abuts against the side of the mounting cavity away from the mounting port.

[0055] Beneficial effects: In the embodiments of this application, users can more easily and conveniently slide the scraping assembly into the mounting cavity of the wringer by utilizing the sliding grooves provided on the top and / or bottom walls of the mounting cavity and the sliding rails provided on the top and / or bottom of the housing of the scraping assembly.

[0056] Furthermore, after the scraping assembly is assembled into the mounting cavity, the slide rail of the housing in the scraping assembly engages with the slide groove of the mounting cavity, thereby further securing the scraping assembly and making it less likely to fall out of the mounting cavity of the wringer, thus improving the user experience.

[0057] According to the present invention, a water-squeezing rack is provided with a slot on the side of the mounting cavity away from the mounting opening;

[0058] The end of the housing is provided with a buckle. The housing is inserted into the mounting cavity from the mounting port along the width direction of the mop board. When the slide rail slides along the slide groove until the end of the housing abuts against the side of the mounting cavity away from the mounting port, the buckle engages with the slot.

[0059] Beneficial effects: In this embodiment, the housing is inserted into the mounting cavity from the mounting opening along the width direction of the mop board. When the slide rail slides along the slide groove until the end of the housing abuts against the side of the mounting cavity away from the mounting opening, the scraping component is more firmly fixed in the mounting cavity by the snap-fit ​​and the slot, improving the stability of the scraping component in the mounting cavity and facilitating the scraping component to clean the wiping material on the mop board. Furthermore, the snap-fit ​​and slot have a simple structure and low manufacturing cost. Using the snap-fit ​​and slot to fix the scraping component in the mounting cavity reduces manufacturing costs.

[0060] According to the present invention, a wringer has an opening on the side of the mounting cavity near the squeezing port, and at least a portion of the scraping member of the scraping assembly extends into the squeezing port through the opening so as to abut against the wiping material of the mop board inserted into the squeezing port.

[0061] Beneficial effects: In this embodiment of the application, by providing an opening on the side of the mounting cavity near the extrusion port, the scraping component can be assembled in the mounting cavity without hindering at least a portion of the scraping part of the scraping component from extending into the extrusion port through the opening, so as to facilitate cleaning of the mop board and improve the user experience.

[0062] Thirdly, this utility model provides a wringer mop, comprising:

[0063] mop handle;

[0064] A mop board, the mop board being connected to one end of the mop handle;

[0065] As described in the second aspect, the wringer is slidably mounted on the mop handle;

[0066] As the wringer slides along the mop handle, the mop plate is inserted into the wringer's squeezing port, causing the scraping assembly in the wringer's mounting cavity to clean the mop plate's wiping surface.

[0067] Beneficial effects: In this embodiment, since the scraper in the scraping assembly is confined within the housing cavity, and the edge of the scraper is surrounded by the side wall of the cavity, the edge of the scraper is isolated from the wringer and mop board by the side wall of the cavity. This avoids damage to the wringer due to its sharp edge when the scraper cleans the mop board, thus extending the service life of the wringer and consequently extending the service life of the mop board.

[0091] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions 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 scope of protection of this utility model.

[0092] In the description of this utility model, it should be clarified that the terms "vertical", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "horizontal", etc., which indicate orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model. They do not mean that the device or element referred to must have a specific orientation or position, and therefore should not be construed as a limitation on this utility model.

[0093] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0094] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0095] The following is combined with Figures 1-11 The present invention describes a scraping component 100, a wringer 200, and a wringer mop 300, which can solve the defect in the related art where the scraping component causes damage to the wringer.

[0096] Reference Figures 1 to 7 In a first aspect, this utility model provides a scraping assembly 100, which is used to be installed on a wringer with a squeezing port and to clean the wiping material on a mop board 302; the scraping assembly 100 includes:

[0097] The housing 101 has a recessed cavity 102;

[0098] A scraper 103 is located within the receiving cavity 102, and the sidewall 1021 of the receiving cavity 102 surrounds the edge of the scraper 103, thereby isolating the edge from external objects.

[0099] In this embodiment, the scraping component 100 can be installed on a cleaning tool such as a mop, and the user can also use the scraping component 100 alone to clean items that need to be cleaned.

[0100] The scraping assembly 100 mainly includes the following key parts: a housing 101 and a scraping component 103. The housing 101 can be made of thermoplastic polymers such as polypropylene or polyethylene, or metals such as aluminum or stainless steel. During the manufacturing of the housing 101, it needs to be recessed inwards to create a receiving cavity 102 inside the housing to accommodate the scraping component 103.

[0101] In practical applications, the scraper 103 can be made of a one-piece molded thermoplastic polymer material, but thermoplastic polymer materials have poor durability and a high wear rate. The scraper 103 can also be made of metal materials such as stainless steel, but the sharp edges of the metal scraper can easily damage other external objects it comes into contact with.

[0102] In some embodiments, the scraper 103 is a plate-shaped structure made of metal, and the plate-shaped structure has a protruding scraping end 1031 for cleaning the wiping object; the sidewall 1021 of the receiving cavity 102 surrounds the edge of the plate-shaped structure.

[0103] In practical applications, the metal material can be stainless steel or aluminum alloy. Because the edges of the plate-shaped structure made of metal are relatively sharp, direct installation on the wringer 200 would damage it during use. By confining the plate-shaped structure made of metal within the receiving cavity 102, with the sidewall 1021 of the receiving cavity 102 surrounding the edge of the plate-shaped structure, and then installing the scraping assembly 100 on the wringer 200, damage to the wringer 200 by the metal scraping part 103 can be avoided.

[0104] Therefore, the scraping assembly 100 provided in this application embodiment, by confining the scraper 103 within the receiving cavity 102 of the housing 101 and utilizing the side wall 1021 of the receiving cavity 102 to surround the edge of the scraper 103, isolates the edge of the scraper 103 from external objects, thereby preventing the scraper 103 from damaging external objects due to its sharp edge when cleaning the wiping material of the mop board 302. Especially when the scraping assembly 100 is installed on the wringer 200, the side wall 1021 of the receiving cavity 102 surrounds the edge of the scraper 103, so that even if there is relative movement between the scraper 302 and the wringer 200 under the action of the mop board 302, the edge of the scraper 103 will not damage the wringer 200, thus improving the service life of the wringer 200.

[0105] Reference Figures 1 to 3 In some embodiments, the scraper 103 is fixed to the receiving cavity 102 by heat fusion head 104.

[0106] In this embodiment, the hot melt head 104 can be made of materials such as plastic or rubber. The user can heat the hot melt head 104 with a hot melt machine and then cool it to allow the hot melt head 104 to re-solidify, thereby fixing the scraper 103 in the receiving cavity 102.

[0107] Through the above implementation method, the scraper is fixed in the receiving cavity by heat fusion head 104, without the need for other fixing methods such as threaded connection or welding, which reduces labor and material costs. In addition, the heat fusion connection method of heat fusion head 104 is simple to operate and takes less time, which simplifies the work process of fixing scraper 103 in receiving cavity 102 and improves work efficiency.

[0108] Reference Figures 2 to 5 In some embodiments, the scraper 103 is provided with an insertion hole 105 near the edge, and the bottom wall 1022 of the receiving cavity 102 is provided with a hot melt head 104 adapted to the insertion hole 105; the hot melt head 104 forms a limiting part after being heated and melted, and the limiting part is used to fix the scraper 103 in the receiving cavity 102.

[0109] In practical applications, the hot melt head 104 can be replaced with a screw, and a matching thread can be provided in the socket 105 to limit the scraping part 103. By providing the socket 105 in the area near the edge of the scraping part 103 and providing the hot melt head 104 that matches the socket 105 in the bottom wall 1022 of the receiving cavity, the limiting part formed after the hot melt head 104 melts can be maximized to be far away from the scraping end 1031 of the scraping part 103, thus avoiding the limiting part from affecting the scraping effect of the scraping part 103.

[0110] Furthermore, by providing an insertion hole 105 near the edge of the scraper 103, a hot-melt head 104 provided on the bottom wall 1022 of the receiving cavity extends out of the insertion hole 105. After the hot-melt head 104 is heated and melted, it forms a limiting part, preventing the limiting part from coming out of the insertion hole 105 of the scraper 103. That is, the combined action of the insertion hole 105 and the limiting part increases the firmness of the scraper 103 fixed in the receiving cavity 102. Moreover, since the hot-melt head 104 re-solidifies after heating and melting, a strong bond is formed between the molecules, making the fixing strength of the limiting part higher than other connection methods, ensuring the stability and durability of the scraper 103 fixed in the receiving cavity 102.

[0111] Reference Figure 2 In some embodiments, the scraper is provided with a protrusion 1051 on the edge of the insertion hole 105, and at least a portion of the insertion hole 105 is formed in the protrusion 1051; an arc-shaped relief groove 1023 is provided in the area of ​​the side wall 1021 of the receiving cavity 102 opposite to the hot melt head 104; when the scraper 103 is provided in the receiving cavity 102, the protrusion 1051 is accommodated in the arc-shaped relief groove 1023.

[0112] In this embodiment, when the user places the scraper 103 into the receiving cavity 102, the insertion hole 105 needs to be aligned with the hot melt head 104, and the hot melt head 104 needs to extend out of the insertion hole 105. When the scraper 103 approaches the receiving cavity 102, the protrusion 1051 is embedded in the arc-shaped relief groove 1023, thereby achieving alignment between the insertion hole 105 and the hot melt head 104.

[0113] Through the above embodiments, since a protrusion 1051 is provided on the edge of the insertion hole 105 of the scraper 103, and the protrusion 1051 can be accommodated in the arc-shaped relief groove 1023, during the process of setting the scraper 103 in the receiving cavity 102, the relative position of the insertion hole 105 and the hot melt head 104 can be quickly positioned with the positioning assistance of the arc-shaped relief groove 1023, making it easier and faster for the hot melt head 104 to extend out of the insertion hole 105, thereby improving the setting efficiency of the scraper 103.

[0114] Furthermore, when the scraper 103 is disposed in the receiving cavity 102, the sidewall of the arc-shaped relief groove 1023 wraps around the protrusion, so that the arc-shaped relief groove 1023 further limits the scraper 103. Under the combined action of the protrusion 1051 and the arc-shaped relief groove 1023, the scraper 103 is prevented from being displaced in the receiving cavity 102, thereby enhancing the firmness of the scraper 103 in the receiving cavity 102.

[0115] In some embodiments, the scraper 103 is provided with a plurality of insertion holes in the area near the two oppositely arranged long edges, and the bottom wall 1022 of the receiving cavity 102 is provided with a plurality of hot melt heads 104 adapted to the insertion holes 105 on the two opposite long edges.

[0116] In this embodiment, multiple heat-sealing heads 104 adapted to the insertion holes 105 are provided, which can form multiple limiting parts to fix the scraper 103, further enhancing the firmness of the scraper 103 within the receiving cavity 102. Furthermore, even if a heat-sealing head 104 or an insertion hole 105 is damaged, other heat-sealing heads or insertion holes can still limit the scraper 103, ensuring the reliability and stability of the scraper 103 fixed within the receiving cavity 102.

[0117] Reference Figures 3 to 6 In some embodiments, the scraping assembly 100 further includes a snap plate 106.

[0118] The buckle plate 106 is disposed on the side of the scraper 103 away from the housing 101 and is snapped into the housing 101 so that the scraper 103 is confined between the receiving cavity 102 and the buckle plate 106.

[0119] In one implementation, the scraper 103 can be heat-fused and fixed in the receiving cavity 102 using the heat-fusion head 104. In another implementation, the snap-fit ​​plate 106 can be engaged with the housing 101 to confine the scraper 103 between the receiving cavity 102 and the snap-fit ​​plate 106, thereby fixing the scraper 103. It is understood that both the heat-fusion head 104 and the snap-fit ​​plate 106 can be used simultaneously to fix the scraper 103.

[0120] In this embodiment, by snapping the buckle 106 to the housing 101, the scraper 103 is confined between the receiving cavity 102 and the buckle 106, thereby further limiting the scraper 103 and making the scraper 103 more firmly fixed in the receiving cavity 102. Furthermore, when using the hot melt head 104 to fix the scraper 103, the buckle 106 is disposed on the side of the scraper 103 away from the housing 101, which can protect the limiting part formed after the hot melt head 104 is heated and melted, and prevent the limiting part from being damaged.

[0121] Furthermore, in some possible implementations, even if the scraper 103 does not have a hot melt head 104 or the limiting part formed after the hot melt head 104 is heated and melted is damaged, the buckle 106 can still limit the scraper 103 between the receiving cavity 102 and the buckle 106, so that the scraper assembly 100 can still clean the wiping material on the mop board 302, thus ensuring the reliability of the scraper assembly 100.

[0122] Reference Figures 3 to 5 In some embodiments, one of the buckle plates 106 and the inner wall of the receiving cavity is provided with a hook 1061 and the other is provided with a buckle groove 1062. The hook 1061 and the buckle groove 1062 are engaged and fastened, so that the scraping member 103 is limited to the receiving cavity 102 and the buckle plate 106.

[0123] In this embodiment of the application, at least one hook 1061 can be provided on the buckle plate 106, and at least one buckle groove 1062 can be provided on the inner wall of the receiving cavity 102; similarly, at least one hook 1061 can be provided on the inner wall of the receiving cavity 102, and at least one buckle groove 1062 can be provided on the buckle plate 106.

[0124] In the above embodiments, the hook 1061 and the slot 1062 have simple structures and low manufacturing costs. Furthermore, the snap-fit ​​connection between the hook 1061 and the slot 1062 makes installation and disassembly very easy. Therefore, the buckle plate 106 and the inner wall of the receiving cavity 102 can be easily and quickly snapped together through the hook 1061 and the slot 1062, thereby allowing the scraping member 103 to be quickly and securely positioned between the receiving cavity 102 and the buckle plate 106.

[0125] In some embodiments, the buckle plate 106 has a buckle hook 1061 extending from the edge toward the housing 101, and the bottom wall 1022 of the receiving cavity has a buckle groove 1062 at the edge near the side wall 1021.

[0126] In this embodiment, the snap plate 106 is easier to replace than the housing 101. Furthermore, the snap hook 1061 is more prone to damage than the snap groove 1062. Therefore, by providing the snap hook 1061 in the snap plate 106 and the snap groove 1062 in the receiving cavity 102, only the snap plate 106 needs to be replaced if the snap hook 1061 is damaged, thus reducing labor and material costs.

[0127] In some embodiments, the edge of the scraper 103 is recessed and provided with a relief groove 1032 corresponding to the hook 1061 and the groove 1062; the hook 1061 passes through the relief groove 1032 and engages with the groove 1062, so that the scraper 103 is limited to the receiving cavity 102 and the buckle plate 106.

[0128] In this embodiment of the application, by providing a recessed relief groove 1032 corresponding to the hook 1061 and the groove 1062 on the edge of the scraper 103, the hook 1061 of the buckle plate 106 can pass smoothly through the edge of the scraper 103, saving the space occupied.

[0129] Furthermore, the hook 106 passes through the relief groove 1032, so that the scraper 103 is restricted in displacement by the combined action of the hook 106 and the relief groove 1032, thereby making the scraper 103 more firmly confined between the receiving cavity 102 and the buckle plate 106.

[0130] Reference Figure 5 In some embodiments, a positioning post 1024 is provided on the bottom wall 1022 of the receiving cavity 102 near the edge, and a positioning hole 1033 is provided on the scraper 103 near the edge. When the scraper 103 is disposed in the receiving cavity 102, the positioning post 1024 is inserted into the positioning hole 1033 to position the scraper 103 in the receiving cavity 102.

[0131] In practical applications, situations may arise where the hot melt head 104 is damaged or the scraper 103 cannot be positioned after the hot melt cools down. Therefore, in this embodiment, a positioning post 1024 is provided near the edge of the bottom wall 1022 of the receiving cavity 102. When the scraper 103 is installed via the buckle plate 106, the positioning post 1024 is inserted into the positioning hole 1033 to achieve a positioning function, thereby positioning the scraper 103 in the receiving cavity 102.

[0132] Reference Figure 4 In some embodiments, the buckle plate 106 is provided with a positioning groove 1063 near the edge of the side close to the housing 101. When the buckle plate 106 is engaged with the housing 101, the end of the positioning post 1024 is inserted into the positioning groove 1063.

[0133] In this embodiment of the application, the positioning groove 1063 can be circular, prismatic, or the like. A limiting rib can also be provided inside the positioning groove 1063 so that after the end of the positioning post 1024 is inserted into the positioning groove 1063, the end of the positioning post 1024 can be further fixed by the limiting rib.

[0134] In the above embodiment, when the buckle 106 is engaged with the housing 101, the end of the positioning post 1024 is inserted into the positioning groove 1063 to position the buckle 106 and the housing 101, making it easier to engage the buckle 106 and the housing 101. Furthermore, by inserting the end of the positioning post 1024 into the positioning groove 1063, the connection between the buckle 106 and the housing 101 is more secure and less likely to fall off.

[0135] Reference Figures 4 to 5 In some embodiments, the area corresponding to the positioning post 1024 on the side wall 1021 of the receiving cavity is provided with an arc-shaped groove 1025, and the edge of the buckle plate 106 is provided with an arc-shaped protrusion 1064.

[0136] When the buckle plate 106 is engaged with the housing 101, the arc-shaped protrusion 1064 is accommodated in the arc-shaped groove 1025 of the receiving cavity sidewall 1021.

[0137] In this embodiment, since an arc-shaped protrusion 1064 is provided on the edge of the buckle plate 106 and the arc-shaped protrusion 1064 is accommodated in the arc-shaped groove 1025 of the side wall 1021 of the accommodating cavity, the relative position of the buckle plate 106 and the accommodating cavity 102 can be quickly positioned with the positioning assistance of the arc-shaped groove 1025 during the buckle plate 106 and the housing 101, making it easier and faster for the buckle plate 106 to be snapped into the housing 101, thus improving the installation efficiency of the buckle plate 106.

[0138] Furthermore, when the buckle 106 is engaged with the housing 101, the arc-shaped protrusion 1064 is accommodated in the arc-shaped groove 1025 of the receiving cavity sidewall 1021. This saves external space while allowing the sidewall of the arc-shaped groove 1025 to wrap around the arc-shaped protrusion 1064, further limiting the buckle 106. Under the combined action of the arc-shaped groove 1025 and the arc-shaped protrusion 1064, displacement of the buckle 106 after being engaged with the housing 101 is prevented, thus enhancing the firmness of the buckle 106 being engaged with the housing 101.

[0139] Reference Figure 5 In some embodiments, the scraping member 103 is provided with a scraping end 1031, and the buckle plate 106 is provided with a window 1065. The scraping end 1031 extends through the window 1065 to the side of the buckle plate 106 away from the housing 101 so as to come into contact with the wiping material of the mop board 302.

[0140] In this embodiment of the application, by providing a window 1065 on the buckle plate 106, the buckle plate 106 can limit the scraping member 103 between the receiving cavity 102 and the buckle plate 106, while not preventing the scraping end 1031 of the scraping member 103 from extending through the window 1065 to the side of the buckle plate 106 away from the housing 101, so as to facilitate the cleaning of the wiping material on the mop board 302.

[0141] Furthermore, the swiping end 103 extends through the window 1065 to the side of the buckle 106 away from the housing 101. The user can observe the usage of the swiping end 1031 through the window 1065, such as the degree of wear of the swiping end 1031, whether there is any wiping residue on the swiping end 1031, etc., which improves the user experience.

[0142] Reference Figure 7In some embodiments, the bottom wall 1022 of the receiving cavity 102 is provided with a hollow window 1026, through which at least a portion of the scraper 103 is exposed.

[0143] In this embodiment, by providing a hollow viewing window 1026 on the bottom wall 1022 of the receiving cavity 102, the user can directly observe the exposed part of the scraper 103 in the hollow viewing window 1026, thereby making it easier for the user to distinguish the type of scraper 103, such as a scraper for wiping water, a scraper for cleaning dirt, a scraper for cleaning hair, etc. Furthermore, the user can also directly observe the usage status of the scraper 103 through the hollow viewing window 1026, such as whether the scraper 103 is damaged or has shifted within the receiving cavity, so that the user can take different measures in a timely manner for different situations, improving the user experience.

[0144] Reference Figures 8 to 10 Secondly, this utility model provides a wringer 200, which includes:

[0145] The body 201 has a squeezing port 202 for inserting a mop board 302, and the side wall of the squeezing port 202 is provided with an installation cavity 203.

[0146] As described in the first aspect, the scraping assembly 100 is detachably assembled in the mounting cavity 203.

[0147] In this embodiment, the scraping component 100 is detachably mounted in the mounting cavity 203 of the wringer 200, so that only the scraping component 100 needs to be replaced when it is damaged, saving labor and material costs. Users can also replace different scraping components 100 in the wringer 200 according to the type of material being wiped on the mop board 302 or the different requirements for the dryness of the material, meeting the user's needs in different scenarios.

[0148] Furthermore, since the scraper 103 in the scraper assembly 100 is confined within the receiving cavity 102 of the housing 101, and the edge of the scraper 103 is surrounded by the side wall 1021 of the receiving cavity 102, the edge of the scraper 103 is isolated from the wringer 200, thereby preventing the scraper 103 from damaging the wringer 200 due to its sharp edge when cleaning the mop board 302, thus extending the service life of the wringer 200.

[0149] Reference Figures 9 to 10In some embodiments, an installation port 2011 is provided on the side wall of the body 201; the scraping assembly 100 is inserted into the installation cavity 203 from the installation port 2011 along the width direction of the mop plate 302 inserted into the squeezing port 202, and the mop plate 302 is inserted into the squeezing port 202 along its length direction.

[0150] In this embodiment of the application, by providing an installation port 2011 on the side wall of the main body 201, the scraping component 100 can be inserted into the installation cavity 203 from the installation port 2011 along the width direction of the mop board 302 inserted into the squeezing port 202 with less effort and convenience.

[0151] On the other hand, the mop plate 302 is inserted into the squeezing port 202 along its length, while the scraping component 100 is inserted into the mounting cavity 203 from the mounting port 2011 provided on the side wall of the main body 201 along the width direction of the mop plate 302 inserted into the squeezing port 202. That is, the direction in which the scraping component 100 is inserted into the mounting cavity 203 is perpendicular to the direction in which the mop plate 302 is inserted into the squeezing port 202. Through the above embodiment, during the process of the mop plate 302 being inserted into the squeezing port 202 along its length, the force direction of the scraping component 100 is perpendicular to the installation direction, thereby making it less likely for the scraping component 100 to fall out of the mounting cavity 203 of the wringer 200, thus improving the user experience.

[0152] In some embodiments, the top and / or bottom walls of the mounting cavity 203 are provided with a groove 2031 extending along the width direction of the mop plate 302, and the top and / or bottom of the housing 101 in the scraping assembly 100 are respectively provided with a slide rail 1011 extending along the width direction of the mop plate 302.

[0153] When the housing 101 is inserted into the mounting cavity 203 from the mounting port 2011 along the width direction of the mop plate 302, the slide rail 1011 slides along the slide groove 2031 until the end of the housing 101 abuts against the side of the mounting cavity 203 away from the mounting port 2011.

[0154] In this embodiment, the user can more easily and conveniently slide the scraping assembly 100 into the mounting cavity 203 of the wringer 200 by using the sliding groove 2031 provided on the top and / or bottom wall of the mounting cavity 203 and the sliding rail 1011 provided on the top and / or bottom of the housing 101 in the scraping assembly 100.

[0155] Furthermore, after the scraping assembly 100 is assembled into the mounting cavity 203, the slide rail 1011 of the housing 101 of the scraping assembly 100 engages with the slide groove 2031 of the mounting cavity 203, thereby further fixing the scraping assembly 100 and making it less likely for the scraping assembly 100 to fall out of the mounting cavity 203 of the wringer 200, thus improving the user experience.

[0156] In some embodiments, a slot 2032 is provided on the side of the mounting cavity 203 away from the mounting port 2011;

[0157] The end of the housing 101 is provided with a buckle 1012. The housing 101 is inserted into the mounting cavity 203 from the mounting port 2011 along the width direction of the mop board 302. When the slide rail 1011 slides along the slide groove 2031 to the end of the housing 101 and abuts against the side of the mounting cavity 203 away from the mounting port 2011, the buckle 1012 engages with the slot 2032.

[0158] In this embodiment, the housing 101 is inserted into the mounting cavity 203 from the mounting opening 2011 along the width direction of the mop plate 302. When the slide rail 1011 slides along the slide groove 2031 until the end of the housing 101 abuts against the side of the mounting cavity 203 away from the mounting opening 2011, the clip 1012 engages with the slot 2032, making the scraping component 100 more firmly fixed in the mounting cavity 203. This improves the stability of the scraping component 100 in the mounting cavity 203 and facilitates the scraping component 100 in cleaning the wiping material on the mop plate 302. Furthermore, the clip 1012 and slot 2032 have a simple structure and low manufacturing cost. Using the clip 1012 and slot 2032 to fix the scraping component 100 in the mounting cavity 203 reduces manufacturing costs.

[0159] In some embodiments, the mounting cavity 203 has an opening 204 on the side near the extrusion port 2011, and at least a portion of the scraping member 103 included in the scraping assembly 100 extends into the extrusion port 2011 through the opening 204 so as to abut against the wiping material of the mop board 302 inserted into the extrusion port 2011.

[0160] In this embodiment of the application, by providing an opening 204 on the side of the mounting cavity 203 near the extrusion port 2011, the scraping assembly 100 is assembled in the mounting cavity 203 without hindering at least a portion of the scraping member 103 of the scraping assembly 100 from extending into the extrusion port 2011 through the opening 204, so as to facilitate cleaning of the wiping material on the mop board 302 and improve the user experience.

[0161] See Figure 11 Thirdly, this utility model provides a wringer mop 300, the wringer mop comprising:

[0162] Mop handle 301;

[0163] Mop board 302, the mop board 302 is connected to one end of the mop handle 301;

[0164] As described in the second aspect above, the wringer 200 is slidably mounted on the mop handle 301;

[0165] When the wringer 200 slides along the mop handle 301, the mop plate 302 is inserted into the squeezing port 2011 of the wringer 200, so that the scraping component 100 in the mounting cavity 203 of the wringer 200 cleans the wiping surface of the mop plate 302.

[0166] In this embodiment, since the scraper 103 in the scraping assembly 100 is confined within the receiving cavity 102 of the housing 100, and the edge of the scraper 103 is surrounded by the side wall 1021 of the receiving cavity 102, the edge of the scraper 103 is isolated from the wringer 200 and the mop board 302 under the wrapping effect of the side wall 1021 of the receiving cavity 102. This avoids damage to the wringer 200 by the sharp edge of the scraper 103 when cleaning the wiping material on the mop board 302, thus extending the service life of the wringer 200 and consequently extending the service life of the mop board 302.

[0167] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
