[0025] The present invention will be described in more detail below with reference to the drawings and examples. [Example]

[0026] Example 1 As shown in Figures 1 to 13, the double mop bucket for a flat mop includes an outer bucket 1, an inner bucket 2 detachably attached to the outer bucket 1, a positioning plug 4 that is inserted through the outer bucket 1 and the inner bucket 2 at the same time, a cover component 001 that is detachably attached to the outer bucket 1, and a water supply component 002 that is attached to the cover component 001 and inserted into the outer bucket 1. A handle 3 is usually rotatably attached to the outer bucket 1, which makes it easy to lift and carry the mop bucket.

[0027] In this embodiment, the outer bucket 1 is provided with a partition plate 1a, which divides the interior of the outer bucket 1 into a clean water area 1b and a dirty water area 1c, the inner bucket 2 is placed in the dirty water area 1c, the positioning plug 4 is inserted through the outer bucket 1 and the inner bucket 2 simultaneously, limiting the separation of the inner bucket 2 and the outer bucket 1, and the water supply component 002 is inserted into the clean water area 1b, the cover component 001 is provided with a cleaning port 001a and a paddle port 001b, which are located above the inner bucket 2, the area of ​​the cleaning port 001a corresponding to the inner bucket 2 is the cleaning area 2a, and the area of ​​the paddle port 001b corresponding to the inner bucket 2 is the paddle area 2b.

[0028] In another embodiment, the external bucket 1 can be installed in two independent bucket bodies, one of which is in the clean water area 1b and the other in the wastewater area 1c, and one bucket body is provided with a base, the other bucket body is installed on the base, and the cover body component 001 is installed to cover the two bucket bodies.

[0029] The flat mop includes a mop head and a mop handle (the flat mop is not shown in the drawings of the specification) that is rotatably attached to the upper end surface of the mop head. When using a mop bucket to wash and dewater the flat mop, the mop head of the flat mop is installed vertically, i.e., the mop head and the mop handle are approximately parallel. The mop head is first inserted into the washing area 2a through the washing port 001a. During insertion, the mop head operates the water supply component 002 to supply water. After washing, the mop head is detached from the washing area 2a and the washing port 001a and inserted into the washing area 2b through the water paddle port 001b to scrape water off the mop head, and the dirty water scraped off from the mop head can flow into the dirty water area 1c.

[0030] As shown in Figures 2 to 5 and 9 to 11, the bottom of the inner bucket 2 is recessed with a groove 2c, which can collect a small amount of dirty water that drips when the flat mop head is washed or paddled, and the width of the groove 2c is smaller than the width of the mop head. The provision of the groove 2c effectively restricts the mop head from being inserted all the way to the bottom, preventing the mop head from coming into contact with the dirty water in the groove 2c when washing or spin-drying, and preventing secondary contamination of the mop head.

[0031] In another embodiment, the bottom of the inner bucket 2 has some protruding ribs, which can be used to limit the mop head of the flat mop from contacting the dirty water at the bottom.

[0032] A drain outlet 11d is provided on one side of the sewage area 1c, and the inner bucket 2 is provided with a drain outlet 32d on this side. When the inner bucket 2 is placed in the sewage area 1c of the outer bucket 1, the drain outlet 11d is aligned with the drain outlet 32d, and the positioning plug 4 is inserted from the outer bucket 1 to the drain outlet 11d and then to the drain outlet 32d in sequence. To prevent water leakage, a waterproof ring (the waterproof ring is not shown in the drawings in the specification) is provided on the positioning plug 4. The waterproof ring is provided in two layers along the insertion direction of the positioning plug 4, with one layer of waterproof ring fitting with the drain outlet 11d and the other layer of waterproof ring fitting with the drain outlet 32d. The waterproof rings prevent water leakage from the drain outlets 11d and 32d. Preferably, the waterproof ring may be a single layer.

[0033] A drain outlet 21f is provided on the side wall of the fresh water area 1b of the external bucket 1, and the drain outlet 21f is convenient for replacing the fresh water remaining in the fresh water area 1b. A water stop plug 5 is removably attached to the drain outlet 21f, and the water stop plug 5 can prevent water leakage from the drain outlet 21f.

[0034] In order to ensure a positioning effect when the inner bucket 2 is placed in the wastewater area 1c of the outer bucket 1, the drain outlet 11d on the outer bucket 1 is provided with a pipe wall 1e extending into the wastewater area 1c, and the drain outlet 11d on the inner bucket 2 is provided with a convex wall 2e extending outward, and the convex wall 2e can be installed on the pipe wall 1e, preferably, the pipe wall 1e has a pipe structure, and the convex wall 2e can have an arc structure, i.e., a local pipe structure.

[0035] A groove 2c is provided within the inner bucket 2, and the wall thickness of the inner bucket 2 is usually consistent, so a recess 2f is formed on the outside bottom of the inner bucket 2. In this embodiment, the recess 2f is located in the center of the inner bucket 2, i.e., on both sides of the outer wall of the groove 2c, and a step 1g that can be inserted into the recess 2f is protruded from the bottom of the wastewater area 1c of the outer bucket 1. When the inner bucket 2 is placed in the wastewater area 1c of the outer bucket 1, the step 1g is inserted into the recess 2f, and the protruding wall 2e is installed on the pipe wall 1e. By fitting these two points, the inner bucket 2 placed within the outer bucket 1 is accurately aligned and can be left stably.

[0036] An outer flange 2g is provided around the upper edge of the inner bucket 2, and the outer flange 2g closest to the partition plate 1a can be attached to the partition plate 1a.

[0037] As shown in Figures 4 to 8 and 13, the lid component 001 includes an upper lid 6, a bottom plate 7, a waterproof lid 8 and a paddle board 9, and the upper lid 6 and the external bucket 1 are removably attached via an engagement structure, the bottom plate 7 is fixed below the upper lid 6, and the cleaning port 001a and the paddle board 001b are provided through the upper lid 6 and the bottom plate 7. In this embodiment, the cleaning port 001a and the flipper port 001b are provided independently, and two escape ports 001e are provided through the cover component 001, one of which is connected to the cleaning port 001a and the other is connected to the flipper port 001b. A waterproof cover 8 is attached above the upper cover 6 and is located on one side of the cleaning port 001a. Sliding grooves 7a are opened on both sides of the bottom plate 7, and the flipper plates 9 are slidably connected to the sliding grooves 7a, and the flipper plates 9 extend partially into the flipper port 001b.

[0038] Preferably, a water inlet 6c is provided through the top cover 6, which allows convenient pouring of water into the fresh water compartment 1b of the outer bucket 1.

[0039] To ensure that the water supply component 002 operates when the mop head is inserted into the cleaning port 001a and that the water supply component 002 can wet the mop head using the water in the clean water area 1b, the cleaning port 001a is located between the paddle opening 001b and the clean water area 1b, i.e., the cleaning area 2a is located between the paddle opening 2b and the clean water area 1b. To prevent the water in the cleaning area 2a from splashing into the clean water area 1b, the inner wall of the bottom plate 7 near the cleaning port 001a and the cleaning area 2a is provided with a downwardly extending lower edge 7d, the lower end of which is lower than the partition plate 1a in the outer bucket 1.

[0040] A connecting pipe 6a that connects the water supply component 002 is provided below the upper cover 6, and the water supply component 002 supplies water through the connecting pipe 6a. The upper cover 6 is provided with a water guide plate 6b located within the cleaning port 001a, and the water shielding cover 8 is attached to the water guide plate 6b. A chamber 001c is formed between the water shielding cover 6 and the water guide plate 6b. The connecting pipe 6a communicates with the chamber 001c. The bottom plate 7 is provided with a toothed plate portion 7b located within the cleaning port 001a, and the toothed plate portion 7b can scrape off anything adhering to the mop head. The water shielding cover 8 has a plurality of through holes 8a, and the water in the chamber 001c can flow from the plurality of through holes 8a along the water guide plate 6b into the cleaning port 001a. In order to further improve the uniformity of the water flow into the cleaning port 001a, a blocking bar 6d is protruded into the chamber 001c, and the water guide plate 6b is located on the side of the blocking bar 6d that is closer to the cleaning port 001a, and the two are connected to each other, and multiple water guide passages are formed between the water guide plates 6b, so that when the water level in the chamber 001c is higher than the blocking bar 6d, overflowing water can flow into all the water guide passages at the same time.

[0041] A water guide groove 001d is formed between the bottom plate 7 and the top cover 6. When the mop head is inserted through the paddle opening 001b, the mop head presses down the paddle board 9, and the bottom plate 7 supports the paddle board 9. That is, the paddle board 9 scrapes off the water on the mop head, and the dirty water and dirt on the mop head scraped off by the paddle board 9 flows along the paddle board 9 into the water guide groove 001d. A water flow outlet 7c is opened on the bottom plate 7, and the water flow outlet 7c is connected to the water guide groove 001d and the dirty water area 1c.

[0042] Meanwhile, when the mop head is raised, the sliding connection between the paddle 9 and the bottom plate 7 allows the mop head to slide the paddle 9. Preferably, the sliding groove 7a is installed at an angle, and the upper end of the sliding groove 7a is farther away from the paddle opening 001b than the lower end, so that when the paddle 9 slides up along the sliding groove 7a, the paddle 9 is farther away from the paddle opening 001b, reducing or even eliminating the paddle effect of the mop head.

[0043] In order to prevent the sewage and dirt scraped off by the paddle board 9 from flowing into the inner bucket 2, the inner bucket 2 is provided with a relief portion 2h, which can ensure that the sewage and dirt flowing out from the water outlet 7c flows into the sewage area 1c of the outer bucket.

[0044] The escape opening 001e is located on the same side of the cleaning opening 001a and the web opening 001b so that the flat mop can be inserted directly into the web opening 001b immediately after being removed from the cleaning opening 001a to scrape off water.

[0045] As shown in Figures 6 to 8 and 12, the water supply component 002 includes a two-cylindrical pipe member 10, a check valve 111, a check valve 212, a piston 13, a tie rod 14, and a gear set 01. The two-cylindrical pipe member 10 includes a pipe body 110a, a pipe body 210b, and a bottom pipe 10c provided at the lower ends of the pipe body 110a and the pipe body 210b, which are arranged in parallel. Both the pipe body 110a and the pipe body 210b are in communication with the bottom pipe 10c. The two-cylindrical pipe member 10 is connected to an external bucket 1. The double-tube member 10 is inserted into the clean water section 1b of the bottom plate 7, and the tube body 110a of the double-tube member 10 communicates with the connecting tube 6a, the check valve 111 is attached to the bottom of the bottom tube 10c, the check valve 212 is attached inside the tube body 110a, and the piston 13 is slidably attached inside the tube body 210b. The piston 12 is rotatably connected to one end of the tie rod 14, and the gear set 01 is rotatably connected to the other end, and the gear set 01 is fixedly attached to the bottom plate 7.

[0046] Preferably, a check valve 111 is used between the clean water area 1b and the bottom pipe 10c to allow the water in the clean water area 1b to flow in one direction into the bottom pipe 10c, and a check valve 212 is used between the bottom pipe 10c and the pipe body 110a to allow the water in the bottom pipe 10c to flow in one direction into the pipe body 110a.

[0047] An attachment port 2i is provided on the bottom plate 7, and the attachment port 2i is connected to the cleaning port 001a. To prevent the two-cylindrical pipe member 10 from coming off the top cover 6, a fixing portion 10d is provided on the two-cylindrical pipe member 10, and the fixing portion 10d can be fixedly connected to the outer wall of one side wall of the attachment port 2i via a screw.

[0048] As shown in Figure 4-7, the gear set 01 includes a driving tooth 15 that is mounted within the mounting port 2i and partially exposed within the cleaning port 001a, a fixed plate 19 that is fixed to the outer wall of the other side of the mounting port 2i, a driven tooth 16 that is rotatably mounted between the fixed plate 19 and the bottom plate 7 and can move with the rotation of the driving tooth 15, an intermediate tooth 17 that is rotatably mounted between the fixed plate 19 and the bottom plate 7 and meshes with the driven tooth 16, and an eccentric tooth 18 that is rotatably mounted on the fixed plate 19 and meshes with the intermediate tooth 17, and an eccentric shaft 18a is provided at the axial end of the eccentric tooth 18 that is offset from the rotational mounting axis, and the eccentric shaft 18a is rotatably connected to the other end of the tie rod 14.

[0049] Rotation transmission between the driven tooth 16 and the driving tooth 15 can be achieved by fitting a spline shaft or a non-circular shaft into a hole, and the rotation axes of the driving tooth 15, driven tooth 16, intermediate tooth 17 and eccentric tooth 18 are perpendicular to the opening direction of the cleaning port 001a.

[0050] In this embodiment, by inserting the mop head of the flat mop into the cleaning port 001a, the lower end surface of the mop head rotates the driving teeth 15, and the driving teeth 15 drive and rotate the driven teeth 16, and rotation is transmitted between the driven teeth 16, the intermediate teeth 17, and the eccentric teeth 18 by meshing, and the eccentric shaft 18a on the eccentric teeth 18 can move the piston 13 up and down within the tubular body 210b of the two-tube pipe member 10 via the tie rod 14 when rotating.

[0051] When the piston 13 moves upward in the pipe 210b, the check valve 111 is opened and the check valve 212 is closed, allowing the water in the clean water chamber 10c to flow into the bottom pipe 10c. When the piston 13 moves downward in the pipe 210b, the check valve 111 is closed and the check valve 212 allows the water in the bottom pipe 10c to flow along the pipe 110a and the connecting pipe 6a to the chamber 001c. The water in the chamber 001c flows through the several through holes 8a onto the water guide plate 6b and into the cleaning port 001a, wetting the mop head.

[0052] Preferably, the number of intermediate teeth 17 is odd, so that the pushing down of the mop head within the cleaning port 001a is synchronized with the downward movement of the piston 13 by the tie rod 14, and the raising of the mop head within the cleaning port 001a is synchronized with the upward movement of the piston 13 by the tie rod 14.

[0053] In other embodiments, the intermediate teeth 17 can be eliminated so that the eccentric teeth 18 and the driven teeth 16 mesh directly together. [Example]

[0054] Example 2 As shown in Figures 14 and 15, unlike the structure of Example 1, the cleaning port 001a on the cover module 001 is connected to the web opening 001b, that is, the escape port 001e connected to the cleaning port 001a is the same as the escape port 001e connected to the web opening 001b, and the escape port 001e is located between the cleaning port 001a and the web opening 001b. After supplying water through the cleaning port 001a to clean the flat mop and removing it, the flat mop needs to be rotated 180 degrees and then inserted into the web opening 001b to scrape off the water. [Example]

The two-tubular pipe member 10 is provided with a pipe member 110a, a pipe member 210b, and a bottom pipe 10c provided at the lower end of the pipe member 110a and the pipe member 210b, which are arranged in parallel. Both the pipe member 110a and the pipe member 210b are connected to the bottom pipe 10c. The two-tubular pipe member 10 is inserted into the fresh water section 1b of the outer bucket 1, and the pipe member 110a of the two-tubular pipe member 10 is connected to the connecting pipe 6a. The connecting pipe 6a is fixed to the lower end of the top cover 6 and is inserted into the upper end of the pipe body 110a with an interference fit. A check valve 111 is attached to the bottom of the bottom pipe 10c and is used to unilaterally introduce water from the clean water area 1b into the bottom pipe 10c. A check valve 212 is attached to the inside of the pipe body 110a and is used to unilaterally introduce water from the bottom pipe 10c into the pipe body 110a. A piston 13 is sealed and slidably attached to the pipe body 210b. One end of the tie rod 14 is rotatably connected to the piston 13, and the other end of the tie rod 14 is directly eccentrically rotatably connected to the friction wheel 20.

[0056] Friction teeth 20a are uniformly arranged on the outer peripheral wall of friction wheel 20 to increase frictional force, and friction wheel 20 is simultaneously connected to the outer wall of bottom plate 7 and the outer wall of pipe body 110a.
