Description

Technical Field

[0001] This utility model belongs to the field of cleaning tools technology, specifically relating to a combined cloth-clamping mop. Background Technology

[0002] A mop is a long-handled cleaning tool used for scrubbing floors, and it also refers to any long-handled cleaning tool. The mop originated from a rag. The most traditional mop was simply a bundle of cloth tied to one end of a long wooden handle; it was simple, inexpensive, and the working head changed from a rag block to a bundle of cloth strips, giving it strong cleaning power.

[0003] The mop head, the working part of the mop, also needs constant cleaning, and the potential harm to the user's hands during cleaning has become a problem that needs to be solved. Therefore, mops have gradually been equipped with wringing and spinning devices, resulting in "wring-dry mops" and "spin-dry mops," solving the problem of drying the mop head without getting hands wet. However, these mop devices have many parts, take up space, and the mop head still accumulates dirt after prolonged use, requiring the entire mop to be discarded and replaced with a new one.

[0004] While flat mops are convenient to use, the mop head still needs to be removed for washing. This led to the development of mops with replaceable mop heads, such as clip-on mops. These mops mostly use Velcro or snap-fit ​​to attach the mop head, but aligning the mop head with the Velcro or snap-fit ​​on the mop head is not very convenient. Furthermore, existing clip-on mops generally only have one clamping device, limiting their use. For example, small mops are suitable for small areas, but struggle with large areas; conversely, large mops are not suitable for small areas. Therefore, a clip-on mop that can handle both small and large areas is needed. Summary of the Invention

Detailed Implementation

[0032] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following describes the combined cloth-clamping mop of this utility model in detail with reference to the embodiments and accompanying drawings.

[0033] <Example>

[0034] This embodiment proposes a modular cloth-clamping mop 100, which can be used with wiping cloths (such as towels, washcloths, etc.). Figure 1 and Figure 2 As shown, the combined mop 100 includes an inner mop assembly 10, an outer mop assembly 20, and a mop handle 30 (the mop 30 has a handle portion, which is prior art and is not shown in the figure). The mop handle 30 is mounted on the inner mop assembly 10, and the inner mop assembly 10 and the outer mop assembly 20 are detachably mounted, so that the inner mop assembly 10 has a connected state relatively fixed to the outer mop assembly 20 and a separated state that is detached from the outer mop assembly 20. That is, the inner mop assembly 10 can be detached from the outer mop assembly 20 for independent use (e.g., ...). Figure 2(As shown). The mop area of ​​the inner mop assembly 10 is smaller than that of the outer mop assembly 20, making it suitable for mopping small areas; when the inner mop assembly 10 is installed on the outer mop assembly 20 (as shown). Figure 1 As shown, the mop area of ​​the inner mop assembly 10 is covered by the outer mop assembly 20, and the outer mop assembly 20 can be used to mop a large area.

[0035] Specifically, the inner mop assembly 10 has an inner body 11, an inner shell 13, and a pair of inner clamping plates 12, such as Figure 3 and Figure 4 As shown, the inner body 11 is rectangular in shape, with a first internal fixing part 111 arranged along its long sides. A pair of inner clamping plates 12 are movable along the X direction (e.g., laterally) on the inner body 11. Each inner clamping plate 12 contains a second internal fixing part 121 that cooperates with the first internal fixing part 111. Both the first internal fixing part 111 and the second internal fixing part 121 have several locking teeth, which are triangular in shape. The locking teeth A1111 on the first internal fixing part 111 and the locking teeth A1111 on the second internal fixing part 121 are... The teeth B1211 are arranged opposite each other and spaced apart. The teeth A1111 and B1211 are used to hold the wiping cloth. When the pair of inner clamps 12 move along the X direction, they have a closed state in which the teeth A1111 and B1211 are brought close to each other and a separated state in which the teeth A1111 and B1211 are moved away from each other. When separated, the wiping cloth clamped between the teeth A1111 and B1211 can be detached. When closed, the wiping cloth can be clamped between the teeth A1111 and B1211.

[0036] A mop handle 30 is installed on the middle of the outer side of the inner housing 13. Driven by the mop handle 30, it moves along the Y direction (the Y direction is perpendicular to the X direction and can be vertical) on the inner body 11. When the mop handle 30 is pressed down, the inner housing 13 moves downward. A drive structure is provided between the inner clamping plate 12 and the inner housing 13. During the movement of the inner housing 13, the drive structure can be driven to control the inner clamping plate 12 to abut against the side of the inner body 11 (i.e., the closed state mentioned above). A drive elastic element 41 is provided on the inner clamping plate 12 or the drive structure. The drive elastic element 41 gives the inner clamping plate 12 a force away from the inner body 11 (i.e., the separated state mentioned above).

[0037] like Figure 5As shown, the driving structure includes a first transmission rod 42 and a second transmission rod 43 that are rotatably connected to each other. Both the first transmission rod 42 and the second transmission rod 43 are inclined, and the connection point between them forms an arched portion 44. During the movement of the inner shell 13, it can act on the arched portion 44 to cause the first transmission rod 42 and the second transmission rod 43 to rotate, thereby driving the inner clamping plate 12 to abut against the inner body 11, that is, the first inner fixing part 111 approaches the second inner fixing part 121 to form a closed state. When the inner shell 13 moves downward, it acts on the arched portion 44, pressing the arched portion 44 downward, causing the end of the first transmission rod 42 or the second transmission rod 43 away from the arched portion 44 to translate to one side, thereby driving the inner clamping plate 12 to translate.

[0038] Specifically, such as Figures 4-6 As shown, a pair of driving structures are provided corresponding to a pair of inner clamping plates 12 (the pair of inner clamping plates 12 includes a left inner clamping plate 12a and a right inner clamping plate 12b). The pair of driving structures includes a left driving structure 40a that drives the left inner clamping plate 12a to move and a right driving structure 40b that drives the right inner clamping plate 12b to move. The left inner clamping plate 12a has a left inner clamping bar 122a arranged along the length direction and a left mounting bar 123a arranged along the width direction. The left inner clamping bar 122a is located on the left side of the inner body 11. The left driving structure 40a is mounted on the left mounting bar 123a. The left driving structure 40a includes a first left transmission rod 42a and a second left transmission rod 43a. One end of the first left transmission rod 42a is rotatably mounted on the inner body 11 through a hinge shaft, and the other end of the first left transmission rod 42a is connected to the second left transmission rod 12a. One end of the second left drive rod 43a is rotatably connected to form a left arched portion 44a. The other end of the second left drive rod 43a is set at the inner end of the left mounting strip 123a through a hinge shaft. A left mounting frame 1231a is also formed at the inner end of the left mounting strip 123a. The drive elastic member 41 has a left drive elastic member 41a, which is installed in the left mounting frame 1231a. The middle part of the left mounting strip 123a protrudes towards the left arched portion 44a to form a left protrusion 1232a. The right inner clamping plate 12b has a right inner clamping strip 122b arranged along the length direction and a right mounting strip 123b arranged along the width direction. The right inner clamping strip 122b is located on the right side of the inner body 11. A right drive structure 40b is mounted on the right mounting strip 123b. The right drive structure 40b includes a first right transmission rod 42b and a second right transmission rod 43b. One end of the first right transmission rod 42b is rotatably mounted on the inner body 11 through a hinge shaft. The other end of the first right transmission rod 42b is rotatably connected to one end of the second right transmission rod 43b to form a right arched portion 44b. The other end of the second right transmission rod 43b is mounted on the inner end of the right mounting strip 123b through a hinge shaft. A right mounting frame 1231b is also formed at the inner end of the right mounting strip 123b. The drive elastic member 41 has a right drive elastic member 41b. The right drive elastic member 41b is mounted in the right mounting frame 1231b. The middle part of the right mounting strip 123b protrudes towards the right arched portion 44b to form a right protrusion.

[0039] When the left arched portion 44a is pressed down, the first left rotating rod 42a rotates along its hinge shaft connected to the inner body 11, and the second left rotating rod 42b rotates along its hinge shaft connected to the left mounting strip 123a, simultaneously moving the left mounting strip 123a to the right, causing the left inner clamping strip 122a to move closer to the inner body 11 (at this time, the left driving elastic element 41a is compressed), thereby clamping the wiping cloth between the left inner clamping strip 122a and the inner body 11; when the right arched portion 44b is pressed down, the first right rotating rod 42b rotates along its hinge shaft connected to the inner body 11, and the second right rotating rod 42b rotates along its hinge shaft connected to the right mounting strip 123b, simultaneously moving the right mounting strip 123b to the right, causing the right inner clamping strip 122b to move closer to the inner body 11 (at this time, the right driving elastic element 41b is compressed), thereby clamping the wiping cloth between the right inner clamping strip 122b and the inner body 11. Therefore, when the inner housing 13 is pressed down by the handle 30, the left arched part 44a and the right arched part 44b can be pressed down at the same time, so that the wiping cloth is clamped between the inner body 11 and the inner clamping plates 12 on both sides, thus completing the installation of the wiping cloth.

[0040] like Figure 3 As shown, the inner main board 11 has two strip-shaped grooves 113 for mounting the left mounting strip 123a and the right mounting strip 123b, respectively. The strip-shaped groove 113 is a groove-shaped structure with one end open and the other end closed. The two strip-shaped grooves 113 are arranged in opposite directions, that is, the open end of one strip-shaped groove 113 faces the left and the open end of the other strip-shaped groove 113 faces the right. A hinge groove is provided on the side plate of the strip-shaped groove 113 near the open end, for the first left rotating rod 42a or the first right rotating rod 42b to be hinged. The closed end is for the left driving elastic member 41a or the right driving elastic member 41b to abut against.

[0041] like Figure 2 and Figure 7As shown, a pair of mounting seats 14 are formed in the middle of the inner housing 13. A mop handle 30 is installed in the space between the pair of mounting seats 14. A limiting buckle 15 is also movably provided on the side of the mounting seat 14 away from the mop handle 30. A limiting hook edge 112 that cooperates with the limiting buckle 15 is provided on the inner body 11. A spring 16 is provided between the rear side of the limiting buckle 15 and the mounting seat 14. The lower end of the spring 16 extends between the inner body 11 and the inner housing 13. A limiting catch edge 151 is provided at the bottom end of the limiting buckle 15. The limiting catch edge 151 can be hooked on the limiting hook edge 112, so that the inner body 11 and the inner clamping plate 12 are always in the state of clamping the wiping cloth. At this time, the inner mop assembly 10 can be used to mop the cloth. After the mop is finished, the limit buckles 15 can be pressed to move them inward and release the engagement between the limit clip 151 and the limit hook 112. Driven by the restoring elastic force of the two driving elastic elements, the arched part 44 is lifted up, thereby pushing the inner shell 13 upward. At this time, the two inner clamps 12 move outward to make the wiping cloth fall off.

[0042] like Figure 2 and Figure 8 As shown, the outer mop assembly 20 has an outer body 21, an outer shell 23, and a pair of outer clamps 22. The outer body 21 has a first outer fixing part 211 on both sides. The pair of outer clamps 22 are movably disposed on the outer body 21 along the X direction and have a second outer fixing part 221 that cooperates with the first outer fixing part 211. The outer shell 23 is fixedly disposed on the outer body 21 and has a downward recess in the middle to form a mounting groove 201 for installing the inner mop assembly 10. The aforementioned inner clamp 12 and outer clamp 22 are detachably installed so that the inner clamp 12 has a connected state that is relatively fixed to the outer clamp 22 and a separated state that is separated from the outer clamp 22. When in the separated state, the inner mop assembly 10 can be used alone. When in the connected state, the outer clamp 22 can be moved under the drive of the inner clamp 12.

[0043] Specifically, the inner clamping plate 12 is provided with an inner clamping strip 122, and a second inner fixing part 121 (with a locking tooth B1211) is provided on one side of the inner clamping strip 122; the outer clamping plate 22 is provided with a first mating part 222 and a second mating part 223, and a mating groove 224 for the inner clamping strip 122 to be inserted is formed between the first mating part 222 and the second mating part 223. The first mating part 222 is located on the side of the inner clamping strip 122 where the second inner fixing part 121 is provided (i.e., the inner side of the inner clamping strip 122); the second mating part 223 is located on the side of the inner clamping strip 122 facing away from the second inner fixing part 121 (i.e., the outer side of the inner clamping strip 122). In this embodiment, as Figure 9 and Figure 10As shown, the first mating part 222 includes a plurality of mating strips 2221 arranged at intervals along the Z direction. Alternating openings 2222 are formed between adjacent mating strips 2221 and between the mating strips 2221 at the ends and the outer casing 23 to avoid the aforementioned locking teeth B1211 and A1111. The second mating part 222 is a long strip-shaped mating strip arranged along its length direction (Z direction). Since the inner clamping strip 122 is embedded in the mating groove 224, when the inner clamping strip 122 moves outward away from the inner main board 11, its outer side abuts against the second mating part 223, pushing the outer clamping plate 22 outward, thus moving the outer clamping plate 22 away from the outer body 21. At this time, the wiping cloth clamped between the outer clamping plate 22 and the outer body 21 can be released. When the inner clamping strip 122 moves inward towards the inner main board 11, its inner side abuts against the first mating part 222, pushing the outer clamping plate 22 inward, thus moving the outer clamping plate 22 closer to the outer body 21. At this time, the wiping cloth can be clamped between the outer clamping plate 22 and the outer body 21, and the outer mop assembly can perform mopping operations. The setting of the clearance opening 2222 allows the inner clamping strip 122 to move inward towards the inner main board 11 without obstruction, avoiding affecting the engagement of the clamping teeth A and B. Correspondingly, the locking teeth A and B are respectively set at the positions of the clearance openings 2222 on the inner main board 11 and the inner clamping strip 122.

[0044] The modular mop 100 also includes a locking component installed within a mounting cavity 24 formed between the outer housing 23 and the outer body 21. This locking component switches the inner mop assembly 10 and the outer mop assembly 20 between a connected state and a disconnected state. A pair of locking components are provided, with identical structures and arranged opposite each other. Figure 11 and Figure 12 As shown, the locking assembly includes a drive rod 31, a connecting rod 32, a locking rod 33, and a locking elastic element 34. The drive rod 31 is movable in the mounting cavity 24 along the Z-direction (perpendicular to the X-direction in the plane) and has an unlocking push block 311 extending out of the outer shell 23. The connecting rod 32 is rotatably disposed in the mounting cavity 24 and located at the end of the drive rod 31 away from the unlocking push block 31. The locking rod 33 is movable in the mounting cavity 24 along the Z-direction and has a locking head 331 extending out of the outer shell 23. The locking elastic element 34 is installed in the mounting cavity 24 and acts on the locking rod 33. A locking opening 131 for the locking head 331 to extend into is provided on the inner shell 13 and / or the inner body 11. In this embodiment, as... Figure 4As shown, the locking port 131 is located on the side of the inner body 11. In other embodiments, the locking port 131 can also be provided on the side of the inner shell 13, or the inner shell 13 and the inner body 11 can each be provided with a semi-locking port, and the two semi-locking ports can be combined to form a locking port 131. When the locking head 331 extends into the locking port 131, the inner mop assembly 10 and the outer mop assembly 20 can be fixed together to form a connected state; when the locking head 331 disengages from the locking port 131, the inner mop assembly 10 can be detached from the outer mop assembly 20 to form a separated state.

[0045] The connecting rod 32 is rotatably mounted in the mounting cavity 24. Both ends of the connecting rod 32 have a driving end 321 that is linked to the driving rod 31 and a locking end 322 that is linked to the locking rod 33. The rotation direction of the driving end 321 is opposite to that of the locking end 322. The driving end 321 has a driving groove 323. The end of the driving rod 31 away from the unlocking push block 311 has a driving hook 312 that can hook onto the driving groove 323. The locking rod 33 has a locking part 332 that cooperates with the locking end 322. In this embodiment, the locking part 332 is a protrusion protruding from the side of the locking rod 33, forming an L-shaped groove between the protrusion and the side of the locking rod 33, allowing the locking end 322 to be inserted. The locking elastic element 34 is located at the end of the locking rod 33 away from the locking head 331 and acts on the locking rod 33 to ensure that the locking rod 33 always has a tendency to move towards the locking port 131. Figure 12 As shown, when the unlocking push block 311 is pushed forward to move the drive rod 31 toward the D1 direction, the drive hook 312 pulls the drive end 321 to rotate forward (clockwise), and the locking end 322 rotates backward (clockwise), thereby driving the locking rod 33 to move backward (toward the D2 direction) and disengage from the locking port 131; when the external force pushing the unlocking push block 311 is removed, the locking rod 33 can be pushed out and inserted into the locking port 131 under the action of the locking elastic member 34.

[0046] One of the outer shell 23 and the outer body 21 is provided with a limiting post, and the other is provided with a fixing hole. The outer shell 23 and the outer body 21 are installed by inserting screws into the fixing hole and fixing them to the limiting post. The outer clamping plate 22 is also provided with a limiting hole 225 for the limiting post to pass through. The limiting hole 225 is elongated to limit the travel of the outer clamping plate 22.

[0047] like Figure 8 and Figure 11As shown, both the first external fixing part 211 and the second external fixing part 221 are provided with a plurality of locking teeth, and the locking teeth on the first external fixing part 211 and the locking teeth on the second external fixing part 221 are arranged at intervals. The locking teeth are triangular in shape. The locking teeth C2111 on the first external fixing part 211 and the locking teeth D2211 on the second external fixing part 221 are opposite to each other and arranged at intervals. The locking teeth C2111 and D2211 are used to clamp the wiping cloth. When the pair of clamping plates 22 moves along the X direction, they have a closed state in which the locking teeth C2111 and D2211 are brought close to each other and a separated state in which the locking teeth C2111 and D2211 are moved away from each other. When separated, the wiping cloth clamped between the locking teeth C2111 and D2211 can be detached. When closed, the wiping cloth can be clamped between the locking teeth C2111 and D2211.

[0048] The combined mop with clip-on cloth proposed in this embodiment has a detachable inner mop assembly and an outer mop assembly. When the inner clip plate is in a relatively fixed connection state with the outer clip plate, the movement of the inner clip plate can drive the outer clip plate to move, thereby enabling the outer mop assembly to work. When the inner clip plate is in a separated state from the outer clip plate, the inner mop assembly can be used independently to adapt to different application scenarios. Alternatively, after the wiping cloth on the inner (outer) mop assembly is used up, it can be replaced with the outer (inner) mop assembly, making it more user-friendly.

[0049] The above embodiments are merely illustrative of specific implementations of the present invention, and the present invention is not limited to the scope of the above embodiments. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
