Description

Technical Field

[0001] The utility model relates to the field of mops, in particular to a flat mop. Background Art

[0002] Homes, small offices, businesses, and biomedical laboratories generally use various types of mops to clean floors. There are three common mops currently available on the market. The first is the traditional mop. This type of mop consists of a mop head attached to a mop handle. While inexpensive, the cloth strips easily fall off and are difficult to wring out, leading to mold and bacterial growth. Based on the traditional mop, wringing mops and spin-drying mops have been developed. These mops incorporate a wringing mechanism or a centrifugal spin-drying mechanism, but they still suffer from issues like inconvenience in drying the cotton, which can lead to mold and bacterial growth, and are also relatively expensive. Another type of mop is the collodion mop. This type of mop uses PVA (polyvinyl alcohol) collodion in the cleaning head. While its advantages are its water absorption capacity and ease of use and dehydration, its disadvantage is that it is not suitable for cleaning grease and chemical-based stains. The third type is the flat mop. Flat mops are currently more common, especially in homes.

[0003] The typical structure of a flat mop is that the mop head adopts a flat design, so that the mop on the bottom plate and the ground are fully stressed and can stick to the hair and fine dust on the ground. In the prior art, such as the "mop device" with application number: CN01227207.8, the connection between the mop and the mop is relatively complicated and inconvenient to assemble and disassemble. As for the relatively convenient connection method, such as directly putting the mop on the mop, it cannot ensure a stable connection between the mop and the mop during use. Therefore, it is very necessary to propose a flat mop. Utility Model Content

DETAILED DESCRIPTION

[0041] The following is a combination of the appended examples of the present invention Figure 1-6 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0042] In the description of this utility model, it should be understood that the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, a feature designated as "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of such features.

[0043] See also Figure 1-6 , embodiments of the present utility model:

[0044] Example 1:

[0045] like Figure 1 Shown: A flat mop, comprising:

[0046] The mop rod 1 and the cleaning plate 2, the middle part of the upper end surface of the cleaning plate 2 is hinged to the mop rod 1, and the upper end surface of the cleaning plate 2 is also provided with a clamping assembly, which is relatively arranged on both sides of the mop rod 1. The clamping assembly includes a pressing plate 3 and abutment 4, and the abutment 4 is arranged on the upper end surface of the cleaning plate 2. The pressing plate 3 is provided with a hinged end 25 and an extension end 26. The hinged end 25 is rotatably connected to the cleaning plate 2, and the extension end 26 extends in a direction away from the mop rod 1 to the abutment 4. The abutment 4 and the extension end 26 are clearance-fitted and are used to clamp the edge of the mop between the pressing plate 3 and the abutment 4.

[0047] Specifically, in this embodiment, each clamping assembly includes a pressure plate 3 and two abutting members 4, that is, four abutting members 4 and two pressure plates 3 are provided on the cleaning plate 2, and the abutting members 4 are located at the edge of the upper end surface of the cleaning plate 2 and are arranged parallel to the side of the cleaning plate 2. The pressure plate 3 is located between the abutting members 4 and the mop rod 1, and the lifting handle 6 is provided on the end surface of the extension end 26, and the abutting members 4 are located on both sides of the lifting handle 6.

[0048] When the handle 6 is pulled upward, the two ends of the mop are bent upward to between the abutting member 4 and the mop rod 1, so that the mop is stably clamped between the pressure plate 3 and the abutting member 4, and the farthest end of the mop is clamped between the pressure plate 3 and the cleaning plate 2, completing the stable connection between one end of the mop and the cleaning plate 2. After the clamping of one end of the mop is completed, the other end of the mop is also bent to the upper end surface of the cleaning plate 2 on the other side. During the operation, the mop is kept in a taut state, so that the mop on the lower end surface of the cleaning plate 2 (that is, the mop used for wiping the part) is more flat. The handle 6 is then turned to hold the mop on the cleaning plate 2, and the two ends of the mop can be clamped between the two ends of the mop by the abutment between the clamping plate and the abutment 4, so that the mop as a whole can be stably fixed to the cleaning plate 2. The whole process only needs to be completed by operating the handle 6 to rotate the clamping plate to complete the disassembly and assembly of the mop, which makes the operation of the present embodiment more convenient. In addition, the mop that can be clamped in the present embodiment only needs to cover the bottom surface of the cleaning plate 2 and be bent to the abutment 4 above the cleaning plate 2. It has strong adaptability to the size and type of the mop. After the mop in the present embodiment completes wiping on one side, the wiping surface contacting the floor can be changed by turning the mop over, that is, both sides of the same mop can be used for wiping, thereby improving the use value of the mop, that is, improving the utilization rate of the mop, compared with the mop set on the mop.

[0049] like Figure 1 and 4 As shown, the extension end 26 is provided with a plurality of protrusions 5 facing the abutting member 4 , and the protrusions 5 and the abutting member 4 are clearance-fitted.

[0050] Specifically, in this embodiment, four protrusions 5 are provided on the end face of each pressure plate 3, and each group of two, that is, each abutment 4 is matched with two protrusions 5. As for the definition of "clearance fit" between the extension end 26 and the abutment 4 and the "clearance fit" between the protrusion 5 and the abutment 4 in the text, it is because the gap between the protrusion 5 and the abutment 4 is smaller than the gap between the extension end 26 and the abutment 4.

[0051] In this embodiment, specifically, a protrusion 5 is added to the end of the pressure plate 3, and there is a gap between each protrusion 5. The protrusions 5 arranged in an interval manner can stably clamp the mop between the protrusion 5 and the abutment 4. In addition, since the mop is mostly made of flexible material, the part not clamped by the protrusion 5 and the abutment 4 will not be deformed, and the part of the mop that has not been deformed will fill the gap between the protrusions 5, that is, the mop will generate friction with the side wall of the protrusion 5 and the part of the extension end 26 located between the protrusions 5, which is equivalent to increasing the contact area between the mop and the pressure plate 3, and further improving the stability of the connection between the mop and the cleaning plate 2.

[0052] like Figure 1 and 4 As shown, the clamping assembly further includes a tilting handle 6 , one end of which is connected to the pressing plate 3 , and the other end of which is tilted away from the upper end surface of the cleaning plate 2 .

[0053] Specifically, in this embodiment, the lifting handle 6 is arranged in an arc shape.

[0054] In this embodiment, by providing a raised handle 6, an operating space can be formed between the handle 6 and the cleaning plate 2. The pressing plate 3 can be easily flipped by pulling the handle 6. When the mop is clamped, the upper surface of the handle 6 is higher than the upper surface of the pressing plate 3 because the handle 6 is raised. Compared with the smaller gap between the upper end surface of the pressing plate 3 and the upper end surface of the cleaning plate 2, the handle 6 with a larger gap with the upper end surface of the pressing plate 3 can make the pressing plate 3 more stable and easier to be subjected to the pressure of the hand, thereby further improving the operational convenience of the present application.

[0055] like Figure 2-4 As shown, the hinged end 25 is provided with at least one first limiting portion 7 , and the upper end surface of the cleaning plate 2 is provided with at least one second limiting portion 8 that can abut against the first limiting portion 7 .

[0056] Specifically, in this embodiment, two first limiting parts 7 and two second limiting parts 8 are provided, which are respectively arranged near the two mounting seats 21. The extending direction of the first limiting part 7 is parallel to the upper end surface of the pressure plate 3, and the extending direction of the second limiting part 8 is perpendicular to the cleaning plate 2. Therefore, when the pressure plate 3 rotates° in the direction away from the cleaning plate 2, the lower end surface of the first limiting part 7 (that is, the side surface after rotation°) is abutted and connected with the inner side surface of the second limiting part 8, completing the rotation limit of the pressure plate 3, preventing the pressure plate 3 from excessively rotating and increasing the operation time, and further improving the convenience of operation of this embodiment.

[0057] like Figure 2-4 As shown, at least one first abutting portion 9 is provided on the upper end surface of the cleaning plate 2 , and the first abutting portion 9 is provided on one side of the second limiting portion 8 , and the end of the hinged end 25 can abut against the upper end surface of the first abutting portion 9 .

[0058] Specifically, in this embodiment, the end surface of the pressure plate 3 close to the end of the mop rod 1 is arranged in an arc shape, so in order to achieve stable abutment between the pressure plate 3 and the first abutment portion 9 after rotation, this embodiment is provided with a second abutment portion 24 at the intersection of this arc surface and the upper end surface of the pressure plate 3, and the end surface of one side of the second abutment portion 24 is flush with the upper end surface of the pressure plate 3, and the other end surface is flush with the part of the arc surface closest to the mop rod 1, so that when the pressure plate 3 in this embodiment rotates away from the cleaning plate 2, the surface of the second abutment portion 24 that is flush with the farthest end of the arc surface tightly abuts against the upper end surface of the first abutment portion 9, cooperating with the first The abutment between the limiting portion 7 and the second limiting portion 8 enables the rotating pressing plate 3 to stably stop in the rotated position, so that when the mop is placed in the position with the entire device, the pressing plate 3 can stably stop at a certain angle without falling due to its own gravity and affecting the initial position of the mop. Specifically, the first limiting portion 7 and the second limiting portion 8 are arranged to limit the rotation direction of the pressing plate 3, and the first abutting portion 9 and the second abutting portion 24 are arranged to support and limit the rotating pressing plate 3, and the supporting direction is the direction in which the extending end 26 of the pressing plate 3 extends after the rotation, so as to ensure that the pressing plate 3 is stably stopped after rotation.

[0059] like Figure 1 and 4 As shown, a plurality of through holes 10 are further provided on the pressing plate 3 , and the through holes 10 are distributed at the edge of the extending end 26 .

[0060] Specifically, in this embodiment, four through holes 10 are provided on each pressure plate 3, and every two through holes 10 form a group, each group of through holes 10 corresponds to an abutment member 4, and the position of each through hole 10 corresponds to each protrusion 5, that is, the through hole 10 is located on one side of the protrusion 5.

[0061] In this embodiment, the through hole 10 corresponds to the protrusion 5 one by one. When the protrusion 5 and the abutment member 4 cooperate to squeeze the rag, a certain deformation space can be provided so that the protrusion 5 can be slightly compressed toward the through hole 10 to prevent the protrusion 5 or the abutment member 4 from breaking.

[0062] like Figure 5-6 As shown: the mop rod 1 includes a handle 11 and a connecting member 12, and the lower end of the handle 11 is hinged to the connecting member 12 through a connecting shaft;

[0063] At least one connecting seat 13 is fixedly provided in the middle of the upper end surface of the cleaning plate 2;

[0064] The lower end of the connecting member 12 is hinged to the connecting seat 13 , and the direction in which the handle 11 rotates around the connecting member 12 is perpendicular to the direction in which the connecting member 12 rotates around the connecting seat 13 .

[0065] Specifically, in this embodiment, two connecting seats 13 are provided, and the connecting member 12 is triangular in shape as a whole;

[0066] In this embodiment, by setting a mutually perpendicular hinge relationship, multi-directional rotation adjustment can be achieved between the handle 11 and the cleaning plate 2 to meet the different usage requirements of different users for this embodiment, so that this embodiment can adapt to a variety of usage scenarios when in use, thereby improving the adaptability of this application.

[0076] Specifically, in this embodiment, the clamping member 19 is a strip-shaped protrusion with a smooth curved surface, and a clamping member 19 is provided on the inner side of each connecting portion 14. The strip-shaped clamping member 19 extends from the edge of the first connecting hole 15 in the direction away from the center axis of the first connecting hole 15, that is, it can be understood that the plane where the center axis of the clamping member 19 is located is perpendicular to the center axis of the first connecting hole 15, and the shape of the clamping groove 20 is set to correspond to the clamping member 19, and the connection between the groove wall of the clamping groove 20 and the inner wall of the connecting portion 14 is also a curved surface. Such a setting can ensure that after each rotation adjustment, the clamping member 19 can be stably connected to the clamping groove 20 while also ensuring smooth rotation adjustment.
