[0032] The core of this utility model is to provide a mop bucket water pumping and cleaning mechanism that directly uses the original limiting roller as a power source to drive the water pump, which simplifies the structure and reduces the failure rate.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] In one specific implementation, such as Figures 1 to 7 As shown, the water pumping and cleaning mechanism for the mop bucket of this utility model is installed on the cleaning spout 103 of the mop bucket body 1, and includes:

[0037] A cleaning spout bracket 2 is used to install the limiting roller 6 and the cleaning assembly. The cleaning spout bracket 2 is detachably installed below the top panel 4 at the top opening of the mop bucket body 1 by screws. A cleaning spout 103 is formed on the top panel 4 and the cleaning spout bracket 2; the top panel 4 is fastened to the top opening of the bucket body 1, and a scraping spout 104 is provided at the end of the top panel 4 away from the cleaning spout 103. The limiting roller 6 limits the mop flat 10 inserted into the cleaning spout 103 from the back, ensuring that the cleaning pad on the front of the mop flat 10 is at a suitable distance from the cleaning assembly. Generally, all mop buckets need to have limiting rollers on the cleaning spout 103; if there are no limiting rollers, limiting protrusions should be provided to abut against the back of the mop flat 10. The cleaning assembly sprays and cleans the cleaning pad on the front of the mop flat 10.

[0038] A water pump 7 is installed in the clean water chamber 101 of the mop bucket body 1. The limiting roller 6 transmits power to the water pump 7 through the transmission assembly, and the water pump 7 pumps water to the cleaning assembly.

[0039] By using the limiting roller 6 as the driving power source for the water pump 7, the power is reused while the mop flat plate 10 is rolled and limited. Compared with the existing technology, this avoids the need to repeatedly set up gear components, simplifies the structure, and reduces the failure rate of the tool.

[0040] This utility model of a clean and dirty separating mop bucket can be produced by simply modifying existing mop bucket molds. It utilizes the existing limiting wheels and adds a corresponding water pump and transmission components, thus reducing the cost of production molds.

[0041] In one specific embodiment of this utility model, such as Figures 3 to 6As shown, the transmission assembly includes a connecting rod 8 and a rocker arm 9. The central shaft of the rocker arm 9 is coaxially and fixedly connected to the central shaft of the limiting roller 6. The two can be integrated as one piece or directly heat-welded together. The central shaft of the limiting roller 6 is horizontally mounted on the support seat of the cleaning spout bracket 2. The lower support rib of the top panel 4 limits the central shaft of the limiting roller 6 within the support seat. The eccentric shaft head 901 of the rocker arm 9 is rotatably connected to the top end of the connecting rod 8. The bottom end of the connecting rod 8 is connected to the piston of the water pump 7, driving the piston to reciprocate linearly to perform a pumping action.

[0042] Specifically, such as Figure 7 As shown, the cantilever end of the eccentric shaft head 901 is a split half-shaft with a clearance in the middle to facilitate smooth installation of the shaft hole at the top of the connecting rod 8.

[0043] By coaxially and fixedly connecting the central shaft of the rocker arm 9 with the central shaft of the limiting roller 6, the transmission structure is simplified, and the rotation of the central shaft is directly converted into the reciprocating linear motion of the piston, thereby improving the kinetic energy efficiency. By making the cantilever end of the eccentric shaft head 901 into a split half-shaft, it is easy to disassemble and install the connecting rod 8.

[0044] In one specific embodiment of this utility model, such as Figure 4 and Figure 5 As shown, the outlet pipe 701 of the water pump 7 extends upward and connects to the water guide channel 401 of the top panel 4, and the water guide channel 401 guides water to the cleaning assembly.

[0045] Specifically, the cleaning assembly includes a clean water cover plate 5, a clean water storage tank on the top panel 4 opposite to the limiting roller 6, a water outlet port of a water guide channel 401 connected to the clean water storage tank, and the clean water cover plate 5 is sealed and fastened to the clean water storage tank. Multiple water outlet holes 501 are provided on the front end of the clean water cover plate 5 facing the cleaning nozzle 103. The multiple water outlet holes 501 are evenly spaced along the front edge of the clean water cover plate 5.

[0046] Specifically, the water cover 5 is made of transparent plastic sheet material.

[0047] The water channel 401 and the clean water storage tank are designed to smoothly guide the water output of the water pump 7. The clean water cover 5 is designed to seal the clean water storage tank and form water outlet holes 501 on the front edge, which spray onto the cleaning pad for rinsing. The clean water cover 5 is made of transparent plastic sheet material, which allows for direct observation of the water flow.

[0048] In one specific embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 5As shown, the cleaning assembly also includes a brush strip 3, which is disposed below the clean water storage tank. The brush strip 3 has bundled stiff bristles. The brush strip 3 cleans the cleaning pad of the mop flat 10.

[0049] Specifically, the cleaning assembly also includes a secondary scraper, which is made of rigid plastic. The secondary scraper is positioned parallel to the bottom of the brush strip 3 and performs partial dehydration on the cleaning pad of the mop flat plate 10. A water guide plate is provided at the bottom of the secondary scraper to guide the wastewater to the wastewater chamber 102 below the mop bucket body 1.

[0050] The brush strip 3 allows for deep scraping and cleaning of the mop pad 10, removing buried dirt and impurities. The secondary scraper added below the brush strip 3 performs semi-drying of the cleaning pad, removing wastewater and facilitating the reabsorption of clean water during the next spray cleaning, thus improving cleaning efficiency.

[0051] In one specific embodiment of this utility model, such as Figures 3 to 6 As shown, there are two limiting rollers 6, which are symmetrically arranged on both sides of the small port of the cleaning nozzle 103. Correspondingly, there are also two sets of the transmission assembly and water pump 7.

[0052] By setting up two sets of transmission components and water pump 7, the water flow rate is increased, ensuring the amount of water used for cleaning. On the other hand, the force on both sides of the back of the mop plate 10 is consistent, preventing tilting. The vertical up-and-down reciprocating motion will not scratch the bucket wall.

[0053] In one specific embodiment of this utility model, such as Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, the limiting roller 6 is a rubber wheel or has a rubber pad sleeve on its outer surface, made of wear-resistant and water-resistant rubber material. A friction strip 1001 is provided on the back of the mop flat plate 10 at the contact point with the limiting roller 6.

[0054] Specifically, such as Figure 8 As shown, the friction band 1001 can be a knurled band with raised and recessed patterns, or it can be an adhesive sandpaper friction strip.

[0055] By using a rubber wheel or having a rubber pad on the outer wheel surface of the limiting roller 6, the friction between the limiting roller 6 and the back of the mop plate 10 can be increased, thereby ensuring that the limiting roller 6 is driven smoothly. By setting a corresponding friction strip 1001 on the back of the mop plate 10, the friction with the limiting roller 6 can be further increased, preventing the limiting roller 6 from slipping.

[0056] The working principle of the mop bucket water pump cleaning mechanism of this utility model is as follows: After the mop to be cleaned is uprighted, the mop flat plate 10 is inserted into the cleaning spout 103, ensuring the mop handle faces the small port of the cleaning spout 103. The friction strip 1001 on the back of the mop flat plate 10 contacts the limiting roller 6. During the insertion and removal of the mop flat plate 10, the two friction strips 1001 drive their respective limiting rollers 6 to rotate. The limiting rollers 6 drive the rocker arm 9 to rotate, and the eccentric shaft head 901 pushes and pulls the top of the connecting rod 8. The bottom of the connecting rod 8 pushes and pulls the piston of the water pump 7, driving the piston to reciprocate linearly to perform the pumping action. The water pump 7 draws clean water from the clean water chamber 101 and guides it to the cleaning assembly along the water outlet pipe 701 and the water guide channel 401. At the same time, after the clean water storage tank is filled with clean water, it is sprayed onto the cleaning pad that moves up and down through the water outlet 501 at the front end of the clean water cover plate 5 to rinse the cleaning pad. The brush strip 3 performs a deep scraping and cleaning of the mop pad 10, removing buried stains and impurities. The secondary scraper semi-dries the cleaning pad, removing wastewater so that the pad can reabsorb clean water during the next spray cleaning, thus improving cleaning efficiency.

[0057] In summary, the mop bucket water pump cleaning mechanism of this utility model uses the limiting roller 6 as the driving power source for the water pump 7. While limiting the rolling motion of the mop flat plate 10, it achieves secondary power utilization. Compared with existing technologies, it avoids the need for redundant gear components, simplifies the structure, and reduces the failure rate of the tool. Furthermore, the coaxial fixed connection between the central shaft of the rocker arm 9 and the central shaft of the limiting roller 6 simplifies the transmission structure, directly converting the rotation of the central shaft into the reciprocating linear motion of the piston, thus improving kinetic energy efficiency. The cantilever end of the eccentric shaft head 901 is a split half-shaft, facilitating the disassembly and installation of the connecting rod 8. The water guide channel 401 and the clean water storage tank ensure smooth water delivery from the water pump 7. The clean water cover plate 5 seals the clean water storage tank and forms water outlet holes 501 on its front edge, spraying water onto the cleaning pad for rinsing. The clean water cover plate 5, made of transparent plastic, allows for direct observation of the water flow. The brush strip 3 allows for deep scraping and cleaning of the mop pad 10, removing buried dirt and impurities. The secondary scraper below the brush strip 3 partially dehydrates the pad, removing wastewater and facilitating reabsorption of clean water during the next rinse, thus improving cleaning efficiency. The two sets of transmission components and water pump 7 increase water flow, ensuring sufficient water for cleaning, and ensure even force distribution on both sides of the mop pad 10's back, preventing tilting and ensuring vertical reciprocating motion without scraping against the bucket wall. The limiting roller 6, made of rubber or with a rubber pad on its outer surface, increases friction between the limiting roller 6 and the back of the mop pad 10, ensuring smooth operation. A friction strip 1001 on the back of the mop pad 10 further increases friction with the limiting roller 6, preventing slippage.

[0058] This utility model also discloses a working method of a mop bucket water pumping and cleaning mechanism. The mop cleaning pad is cleaned using the mop bucket water pumping and cleaning mechanism in any of the above embodiments. The limiting roller on the cleaning spout is used as a power source to output power to the water pump to pump water and spray to clean the cleaning pad of the mop flat.

[0059] The water pump is driven by a friction wheel, eliminating the need for a separate rack and pinion, simplifying the structure and avoiding gear jamming. The short transmission chain also reduces resistance during cleaning.

[0060] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
