Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning products technology, and in particular to a dual-pump mop bucket that separates clean and dirty parts. Background Technology
[0002] The cleaning and wringing process for flat mops on the market mostly involves inserting the mop head into the clean water reservoir through the cleaning spout of the mop bucket for soaking and washing, and then inserting it into the squeegee spout to wring out the water using a squeegee. This process removes dirt from the mop head while simultaneously squeezing out the water, and the wastewater flows back into the clean water reservoir. This type of mop is simple, economical, and practical, and is relatively common. However, because wastewater flows into the clean water reservoir, the water in the reservoir cannot be guaranteed to be thoroughly cleaned. After repeated use, the water becomes wastewater and is no longer effective at cleaning the mop.
[0003] Currently, many mop buckets now feature separate cleaning and soiling functions, abandoning soaking for a more efficient method. Instead, they use a pump-driven spray system to clean the cleaning pad of the flat mop, ensuring continuous cleaning with clean water. Utility model patent CN217610946U discloses a mop cleaning device with a soiling drainage system. This patent uses a water supply mechanism that pumps clean water from a storage chamber to spray and clean the mop. However, its cleaning and drying nozzles are combined into one, requiring the mop to be moved left and right when switching between cleaning and drying functions. Utility model patent CN220236814U discloses a mop cleaning device with visualized water spray status. This technology uses water flow to move a display indicator, allowing users to observe the dynamic information or positional changes of the indicator in a visual window to determine whether the pump is operating.
[0004] While existing clean and dirty water separation mop buckets achieve the separation of clean and dirty water, when the mop is sprayed in the washing chamber, dirty water drips downwards. This dirty water accumulates in the chamber, raising the liquid level and causing the bottom of the mop, which is inserted at its lowest position, to be soaked, resulting in secondary pollution. Therefore, it is necessary to raise the mop bucket or drain the dirty water multiple times to avoid this secondary pollution, which brings many inconveniences to operation.
[0005] Therefore, it is necessary to develop a dual-pump mop bucket that separates clean and dirty parts to address the aforementioned shortcomings. Utility Model Content
[0006] The purpose of this invention is to provide a dual-pump mop bucket with a more rational cavity partitioning, featuring an independent cleaning chamber separate from the wastewater chamber; and using a pump to extract wastewater accumulated at the bottom of the cleaning chamber into the wastewater chamber, thus avoiding secondary pollution during the cleaning process.
[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0008] This utility model relates to a dual-pump clean and dirty separation mop bucket, which includes a cleaning spout component, a cleaning chamber, and a clean water pump set. The clean water pump set pumps clean water to the cleaning spout component to spray and rinse the flat tray. A return water pump set is provided at the bottom of the cleaning chamber, which pumps the sewage accumulated at the bottom of the cleaning chamber to the sewage chamber that is isolated below.
[0009] Furthermore, it also includes an upper tub, a lower tub, a top panel, and a scraper / squeegee assembly. The lower tub is detachably and tightly fitted onto the bottom opening of the upper tub via two symmetrically arranged snap-on covers on the top. The top panel is snapped onto the top opening of the upper tub, and the cleaning and scraper / squeegee assemblies are centrally arranged at both ends of the top panel. The cleaning chamber and the scraper / squeegee chamber are respectively located directly below the cleaning and scraper / squeegee assemblies. The upper tub has a clean water chamber spaced between the cleaning chamber and the scraper / squeegee chamber, and the clean water pump assembly is located at the bottom of the clean water chamber.
[0010] Furthermore, both the clean water pump set and the return water pump set are plunger pumps, and the pistons are poweredly connected to the main shaft of the limiting roller of the cleaning nozzle component through a crank-connecting rod structure.
[0011] Furthermore, it also includes a lower extension housing, which is disposed on the top of the lower tub. The lower extension housing has downwardly recessed relief grooves at corresponding positions in the washing chamber and the squeegee chamber, respectively. The relief grooves can accommodate the bottom end of the inserted mop flat plate. The wastewater dripping from the washing chamber and the squeegee chamber collects in the relief grooves. The main body of the return water pump unit is disposed in the relief groove below the washing chamber. The outlet of the return water pump unit passes through the side wall of the washing chamber and pumps water back to the wastewater chamber below.
[0012] Furthermore, the two relief grooves are connected by a passageway.
[0013] Furthermore, the upper tank body has a water pump clearance protrusion protruding downward on the bottom plate of the clear water chamber, and the main body of the clear water pump assembly is installed in the groove of the water pump clearance protrusion.
[0014] Furthermore, the upper barrel body has two symmetrically arranged positioning posts protruding downwards from the bottom plate of the clear water chamber, and the lower extended shell has positioning slots that fit in place at the positions of the positioning posts.
[0015] Furthermore, a handle is provided on the top outer wall of the upper bucket; a drain hole is provided on the side wall of the lower bucket, and a plug is inserted into the drain hole.
[0016] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0017] This utility model features a dual-pump mop bucket with separate cleaning and wastewater compartments. By adding a return water pump unit at the bottom of the cleaning chamber, it collects wastewater dripping to the bottom of the cleaning chamber and pumps it to the wastewater chamber. This prevents wastewater from accumulating at the bottom of the cleaning chamber and rising to the surface, thus avoiding secondary contamination of the flat mop when it is inserted to its lowest position. The dual-pump mop bucket also features a more rationally divided chamber design, with a separate cleaning chamber from the wastewater chamber. The pump method draws accumulated wastewater from the bottom of the cleaning chamber into the wastewater chamber, preventing secondary contamination during the cleaning process.
[0018] Furthermore, the cleaning and squeegee components are centrally arranged at both ends of the top panel, consistent with traditional soaking mop buckets. This upgrade to a clean / dirty separation bucket adheres to user habits and is easily accepted by consumers. By using a clean water chamber to separate the cleaning and squeegee chambers, interference between them is avoided, and a water pump can be easily placed nearby. The clever use of limiting rollers as the pumping power eliminates the need for a separate rack and pinion mechanism on the back of the flat plate, simplifying the power components and ensuring operational reliability. A detachable lower extension shell with recessed grooves extends the lower space of the cleaning and squeegee chambers, facilitating cleaning and maintenance during use. A passageway connecting the two recessed grooves allows wastewater accumulated at the bottom of the squeegee chamber to be promptly pumped into the wastewater chamber, preventing secondary contamination of the flat mop within the squeegee chamber. By designing a raised section to accommodate the water pump, the installation position of the clean water pump unit is lowered, allowing for almost complete pumping of clean water from the clean water chamber and preventing spoilage caused by long-term water accumulation. The cooperation between the positioning post and the positioning slot improves the connection stability between the upper and lower tanks. Attached Figure Description

[0027] The core of this utility model is to provide a dual-pump mop bucket with a more reasonable cavity partitioning, setting up an independent cleaning chamber that is separate from the sewage chamber; and using a pump to extract the sewage accumulated at the bottom of the cleaning chamber into the sewage chamber, thus avoiding secondary pollution during the cleaning process.
[0028] 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.
[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.
[0030] Refer to the attached diagram. Figure 1 This is a three-dimensional structural diagram of the dual-pump clean and dirty separation mop bucket of this utility model; Figure 2 This is a schematic diagram of the main structure of the dual-pump clean and dirty separation mop bucket of this utility model; Figure 3 for Figure 2 Schematic diagram of the cross-sectional structure of the middle AA section; Figure 4 for Figure 2 Schematic diagram of the cross-sectional structure of the middle BB section; Figure 5 This is a three-dimensional structural diagram of the present invention after removing the top panel and the upper barrel body; Figure 6 This is a three-dimensional structural diagram of the upper barrel of this utility model.
[0031] In one specific implementation, such as Figures 1-6 As shown, this utility model's dual-pump clean and dirty separation mop bucket includes a cleaning spout component 5, a cleaning chamber 11, and a clean water pump unit 8. The cleaning chamber 11 is located directly below the cleaning spout component 5. The clean water pump unit 8 pumps clean water to the cleaning spout component 5, and the spray head of the cleaning spout component 5 sprays clean water onto the flat tray to rinse the cleaning pad. A return water pump unit 9 is provided at the bottom of the cleaning chamber 11, and the return water pump unit 9 pumps the dirty water accumulated at the bottom of the cleaning chamber 11 to the lower isolated dirty water chamber 13.
[0032] By adding a return water pump unit 9 at the bottom of the cleaning chamber 11, the wastewater dripping to the bottom of the cleaning chamber 11 can be collected and pumped to the wastewater chamber 13. This prevents wastewater from accumulating at the bottom of the cleaning chamber 11 and continuously rising to the surface, thus avoiding secondary contamination of the flat mop by the rising wastewater when it is inserted to its lowest position. This utility model features a dual-pump clean and dirty separation mop bucket with a more rational chamber partitioning, setting up an independent cleaning chamber separate from the wastewater chamber; and using a pump to extract the wastewater accumulated at the bottom of the cleaning chamber to the wastewater chamber, avoiding secondary contamination during the cleaning process.
[0033] In one specific embodiment of this utility model, such as Figures 1-6 As shown, the dual-pump clean and dirty separation mop bucket of this utility model also includes an upper bucket body 1, a lower bucket body 2, a top panel 4, and a squeegee / squeegee assembly 6. The lower bucket body 2 is detachably and tightly fitted onto the bottom opening of the upper bucket body 1 by two symmetrically arranged snap-on covers 3 at the top. That is, the snap-on covers 3 press the lower bucket body 2 tightly onto the bottom opening of the upper bucket body 1, and the upper bucket body 1 and the lower bucket body 2 can be separated by flipping the snap-on covers 3 upwards. The inner cavity of the lower bucket body 2 is a dirty water chamber 13. The top panel 4 is snapped onto the top opening of the upper bucket body 1, and the cleaning / squeegee assembly 5 and the squeegee / squeegee assembly 6 are centrally arranged at both ends of the top panel 4. The cleaning chamber 11 and the squeegee / squeegee chamber 12 are respectively located directly below the cleaning / squeegee assembly 5 and the squeegee / squeegee assembly 6. The upper bucket body 1 has a clean water chamber 10 between the cleaning chamber 11 and the squeegee / squeegee chamber 12, and the clean water pump assembly 8 is located at the bottom of the clean water chamber 10.
[0034] The cleaning nozzle component 5 and the drying nozzle component 6 are arranged in the center at both ends of the top panel 4, which is consistent with the traditional soaking mop bucket. Even though it is upgraded to a clean and dirty separation bucket, it follows the user's operating habits and is easy to gain consumer approval. By using a clean water chamber 10 to separate the cleaning chamber 11 and the drying chamber 12, the cleaning chamber 11 and the drying chamber 12 are prevented from interfering with each other, and at the same time, it is convenient to set up a water pump nearby for pumping water.
[0035] In one specific embodiment of this utility model, such as Figures 3-5As shown, both the clean water pump group 8 and the return water pump group 9 are plunger pumps, and the pistons are powered by the crank connecting rod structure and connected to the main shaft of the limiting roller 501 of the cleaning nozzle component 5.
[0036] Obviously, the clean water pump set 8 and the return water pump set 9 can also be small electric submersible pumps, which require batteries and control panels. They can also achieve the functions of pumping water for spraying and discharging wastewater. Similar simple replacement methods all fall within the protection scope of this utility model.
[0037] By cleverly utilizing the limit roller 501 as the power source for the pump, the need for a separate rack and gear mechanism on the back of the flat plate is avoided, simplifying the power components and ensuring operational reliability.
[0038] In one specific embodiment of this utility model, such as Figure 4 and Figure 5 As shown, the dual-pump clean and dirty separation mop bucket of this utility model also includes a lower extension shell 14, which is disposed on the top of the lower bucket body 2. The outer folded edge of the top of the lower extension shell 14 is adapted to the inner contour of the top of the lower bucket body 2. The lower extension shell 14 is provided with downwardly recessed relief grooves at corresponding positions of the washing chamber 11 and the squeegee chamber 12. The relief grooves can accommodate the bottom end of the inserted mop flat plate. That is, the upper bucket body 1 has bottom openings at the washing chamber 11 and the squeegee chamber 12, and the relief grooves are extensions of the lower space of the washing chamber 11 and the squeegee chamber 12. The wastewater dripping from the washing chamber 11 and the squeegee chamber 12 collects in the relief grooves. The main body of the return water pump group 9 is disposed in the relief groove below the washing chamber 11. The outlet of the return water pump group 9 passes through the side wall of the washing chamber 11 and pumps water back to the wastewater chamber 13 below.
[0039] It should be noted that the top wall of the lower extended housing 14 has drainage holes on one side of the cleaning sidewall and the drying sidewall of the cleaning chamber 11 and the drying chamber 12. That is, most of the sewage flowing down the cleaning sidewall and the drying sidewall directly enters the sewage chamber 13 through the drainage holes mentioned here. Only a small portion of the sewage flowing down the sidewall and the dripping sewage collects in the relief groove and is pumped by the return water pump unit 9.
[0040] Specifically, such as Figure 4 and Figure 5 As shown, the two relief grooves are connected by a passageway 15. The bottom surface of the passageway 15 is flush with the bottom surface of the relief grooves.
[0041] By providing a detachable lower extension housing 14, and forming the clearance groove on the lower extension housing 14 as an extension of the lower space of the washing chamber 11 and the squeegee chamber 12, cleaning and maintenance during use are facilitated. By adding a passageway 15 between the two clearance grooves, the wastewater accumulated at the bottom of the squeegee chamber 12 can also be pumped into the wastewater chamber 13 in a timely manner, avoiding secondary pollution of the flat mop in the squeegee chamber 12.
[0042] In one specific embodiment of this utility model, such as Figure 5 and Figure 6 As shown, the upper barrel 1 has a water pump clearance protrusion 102 protruding downward on the bottom plate of the clear water chamber 10, and the main body of the clear water pump group 8 is installed in the groove of the water pump clearance protrusion 102.
[0043] By setting the water pump clearance protrusion 102, the installation position of the clean water pump set 8 is lowered, which can almost completely pump the clean water in the clean water chamber 10, avoiding the deterioration caused by long-term accumulation of clean water.
[0044] In one specific embodiment of this utility model, such as Figure 5 and Figure 6 As shown, the upper barrel 1 has two symmetrically arranged positioning posts 101 protruding downwards from the bottom plate of the clear water chamber 10, and the lower extended shell 14 has positioning slots that fit in place at the positions of the positioning posts 101.
[0045] The connection stability between the upper barrel 1 and the lower barrel 2 is improved by the cooperation of the positioning post 101 and the positioning slot.
[0046] In one specific embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 5 As shown, a handle 7 is provided on the top outer wall of the upper bucket 1, and the base of the handle 7 is rotatably installed in the shaft hole at the top of the upper bucket 1 via a pivot. A drain hole is provided on the side wall of the lower bucket 2, and a plug 16 is inserted into the drain hole. The rubber plug 16 is also provided with a handle head.
[0047] The process of using this utility model dual-pump clean and dirty separation mop bucket is as follows: The operator holds the handle of the flat tray and inserts it into the cleaning spout component 5 for cleaning. The flat tray, carrying the cleaning pad, moves up and down reciprocally within the cleaning chamber 11, driving the limiting roller 501 to rotate forward or backward. The limiting roller 501 drives the pistons of the clean water pump group 8 and the return water pump group 9 via a crank connecting rod. The clean water pump group 8 in the clean water chamber 10 pumps clean water to the spray head of the cleaning spout component 5, and the spray head sprays water onto the cleaning pad to clean it. Some of the dirty water dripping from the cleaning pad collects in the relief groove at the bottom of the cleaning chamber 11. At the same time, the return water pump group 9 pumps the dirty water collected in the relief groove of the cleaning chamber 11 and the dripping from the scraping chamber 12 to the lower dirty water chamber 13, preventing the dirty water from accumulating at the bottom of the cleaning chamber 11 and causing secondary pollution to the bottom of the flat tray.
[0048] In summary, this utility model of a dual-pump mop bucket with separate cleaning and soiling compartments, by adding a return water pump unit 9 at the bottom of the cleaning chamber 11, can collect the wastewater dripping to the bottom of the cleaning chamber 11 and pump it to the wastewater chamber 13. This prevents wastewater from accumulating at the bottom of the cleaning chamber 11 and continuously rising to the surface, thus avoiding secondary contamination of the flat mop when it is inserted to its lowest position by the rising wastewater. This utility model of a dual-pump mop bucket with separate cleaning and soiling compartments has a more rational cavity partitioning, with an independent cleaning chamber separate from the wastewater chamber; and it uses a pump to extract the wastewater accumulated at the bottom of the cleaning chamber to the wastewater chamber, avoiding secondary contamination during the cleaning process. Furthermore, the cleaning spout component 5 and the drying spout component 6 are centrally arranged at both ends of the top panel 4, consistent with traditional soaking mop buckets. This upgrade to a clean / dirty separation bucket adheres to user habits and is easily accepted by consumers. By using a clean water chamber 10 to separate the cleaning chamber 11 and the drying chamber 12, mutual interference between them is avoided, and a water pump can be conveniently located nearby. The clever use of the limiting roller 501 as the pumping power eliminates the need for a separate rack and pinion mechanism on the back of the flat plate, simplifying the power components and ensuring operational reliability. A detachable lower extension housing 14, with recessed grooves formed on it, extends the lower space of the cleaning chamber 11 and the drying chamber 12, facilitating cleaning and maintenance during use. By adding a passageway 15 between the two recessed grooves, the wastewater accumulated at the bottom of the squeegee chamber 12 can be promptly pumped into the wastewater chamber 13, preventing secondary contamination of the flat mop within the squeegee chamber 12. The water pump recess protrusion 102 lowers the installation position of the clean water pump assembly 8, enabling almost complete pumping of clean water from the clean water chamber 10, preventing deterioration caused by long-term water accumulation. The cooperation between the positioning post 101 and the positioning slot improves the connection stability between the upper tub 1 and the lower tub 2.
