[0030] like Figure 4-7 As shown, the utility model discloses a second embodiment of a mop bucket, which includes: a bucket shell 100 having a sewage chamber 120 and a cleaning module 200, a scraping device 300 arranged at one end of the bucket shell 100 and adjacent to the cleaning module 200, a bucket inner ring 400 arranged on the inner wall of the bucket shell 100 and around the top of the bucket shell, a cover member 500 arranged on the bucket inner ring 400 and at least partially shielding the top of the sewage chamber 120, a handle 700 arranged on the bucket inner ring 400 and adjacent to the cover member 500 and rotatable, a garbage box 600 arranged at one side of the scraping device 300 and collecting large particles of garbage and allowing sewage to pass through, and a pair of rollers 720 arranged opposite to the scraping device 300 and located above the cleaning module 200, wherein the scraping device 300 is the scraping device 300 in the first embodiment.

[0031] The barrel shell 100 is generally rectangular and can be placed on a horizontal plane, extending in a direction perpendicular to the horizontal plane. The barrel shell 100 includes a pair of snap-on flanges 110 located at the top and pivotally connected to one end of the handle 700, a clean water chamber 140 arranged in parallel with the sewage chamber 120, and a partition plate 160 for separating the sewage chamber 120 and the clean water chamber 140 in a direction perpendicular to the horizontal plane. The volume of the clean water chamber 140 is greater than that of the sewage chamber 120. The clean water chamber 140 is used to provide cleaning liquid or clean water, while the sewage chamber 120 is used to collect sewage.

[0032] The cleaning module 200 is an integral injection molded part, which has a cleaning chamber 220 for at least partially accommodating a rag, and an overflow hole 240, one end of which is connected to the cleaning chamber 220 and the other end of which is connected to the sewage chamber 120 and is disposed near the barrel inner ring 400. The cleaning chamber 220 and the sewage chamber 120 are independent of each other. In this embodiment, the cleaning chamber 220 is at least partially surrounded by the sewage chamber 120. The cleaning module 200 is detachably extended into the sewage chamber 120, and its top end is fixedly connected to the cover plate 500.

[0033] The scraping device 300 is an integral injection molded part, which extends along the width direction of the rag, and the cross section of the base 310 in this direction is roughly triangular. The comb tooth portion 320 occupies one corner of the triangle, the scraping portion 340 occupies the second corner of the triangle, and the fixing portion 360 occupies the third corner of the triangle. The cumulative cross-sectional area of ​​the water inlet 380 is smaller than the cross-sectional area of ​​the water outlet 382.

[0034] The shape of the barrel inner ring 400 is similar to the cross-sectional shape of the barrel outer shell 100 . It is disposed above the partition plate 160 and is snap-fastened to the inner wall of the barrel outer shell 100 . The barrel inner ring 400 surrounds the top of the sewage chamber 120 and the clean water chamber 140 and is located on the inner side of the snap flange 110 and is annular, and includes an inner ring fixed end 420 located at one end, an inner ring opening 422 formed on the inner ring fixed end 420 and in a T-shape, a connecting rod 424 arranged adjacent to the inner ring opening 422, a snap protrusion 425 located on the outside and snap-connected to the inner wall of the barrel shell 100, a pair of fixing holes 426 located at both ends of the connecting rod 424 and correspondingly matched with the corresponding fixing parts 360, a plurality of snap arms 427 located on the outside and snap-connected to the cleaning module 200, a pair of roller grooves 428 located on both sides of the inner ring opening 422 and accommodating the roller 720, and a pair of inner ring flanges 429 aligned with the snap flange 110 and pivotally connected to one end of the handle 700.

[0035] The cover plate 500 is disposed on the barrel inner ring 400, and includes a first insertion port 520 for allowing a rag to be inserted, a second insertion port 540 disposed adjacent to the first insertion port 520, and a garbage discharge passage 560 located inside and between the first insertion port 520 and the second insertion port 540. The length direction of the first insertion port 520 is the width direction of the barrel shell 100, and is consistent with the width direction of the rag. The inner ring opening 422 is disposed corresponding to the first insertion port 520 to allow the rag to pass through.

[0036] The trash box 600 includes a plurality of bottom holes 622 at the bottom, a box cover plate 680 at the top, and a receiving cavity therein.

[0037] The handle 700 is U-shaped and can rotate around the center of the snap flange 110 and can be in an upright state or a horizontal state. When in the horizontal state, the handle 700 is in contact with the barrel inner ring 400 and is located on the inner side of the barrel outer shell 100 .

[0038] like Figure 8 As shown, a flat mop 800 is applied to the mop bucket of this embodiment, and the mop 800 includes a mop rod 820, a rag plate 840 pivotally connected to the bottom of the mop rod 820 and inserted into the cleaning module 200, and a rag 860 detachably connected to the rag plate 840. The rag plate 840 can be detachably connected to the rag 860 via Velcro.

[0039] During operation, the rag 860 with dirt and garbage is moved downward inside the cleaning module 200 and firstly interfered with the comb tooth portion 320 to separate large particles of garbage from the rag 860, and the garbage enters the garbage box 600 through the garbage discharge channel 560. At this time, the rag 860 is usually dry and does not contain dirty water; then the rag 860 continues to move downward until the rag 860 contacts the cleaning liquid in the cleaning chamber 220, so that the rag 860 is immersed in the cleaning liquid, and the dirt on the rag is dissolved in the cleaning liquid; then the rag 860 is moved upward, the rag 860 encounters the wiper portion 340, and the dirty water on the rag 860 is squeezed into the cleaning chamber 220 until the rag 860 is cleaned. 0 leaves the wiper portion 340, and during the multiple cycles of the up-and-down movement of the rag, even if there is sewage in the rag 860, it can flow back into the cleaning chamber 320 through the water inlet 380 for water replenishment, and once there is too much cleaning liquid in the cleaning chamber 320 or during the up-and-down reciprocating movement of the rag 860, the cleaning liquid in the cleaning chamber 320 can enter the sewage chamber 120 through the overflow hole 240; the sewage in the cleaning chamber 320 moves in the cleaning chamber below the wiper portion 340 and in the narrow closed space around the rag 860, and can only overflow into the sewage chamber 120 through the overflow hole 240; finally, the rag 860 continues to move upward until it is taken out of the cleaning module 200 to the end.

[0040] Therefore, the water scraped from the rag by the utility model basically returns to the cleaning chamber, or randomly flows into the cleaning chamber through the water outlet, and most of the sewage flows from the cleaning chamber to the sewage chamber through the overflow hole when the mop is washed up and down. This ensures that the cleaning chamber has sufficient water to wash the rag multiple times, and the water gradually overflows to drain the cleaning chamber; while large particles of garbage are collected in the garbage box.

[0041] The utility model has the advantages of separating large-particle garbage in advance to reduce sewer blockage, and squeezing water out of the rag at the same time to avoid excessive water content of the rag when it is used.

[0042] The above are only preferred implementations of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technician familiar with the technical field can make several modifications and improvements without departing from the creative concept of the present utility model, which should be included in the protection scope of the present utility model.
