Description

[Technical Field]

[0001] The present invention relates to the technical field of cleaning tools, and more particularly to a mop bucket pumping cleaning mechanism. [Background technology]

[0002] The most commonly used cleaning and dehydrating method for flat mops on the market is to immerse the mop in the clean water area, then install a water wringer in the bucket and dehydrate it with the wiper blades, wringing out the water and wiping while simultaneously removing dirt from the mop head and returning the dirty water to the clean water area. This type of mop is simple in structure, economical, and practical. However, currently available flat mops use the clean water area for immersion cleaning, and the water cannot be used to ensure thorough cleaning. After repeated use, the water becomes dirty, making it difficult to effectively clean the mop.

[0003] Recently, many mop buckets have emerged that separate the dirty and clean parts, and instead of immersion cleaning, they use a pumping and spraying method to spray and clean the flat mop cleaning pad. Invention patent publication number CN217610946U discloses a mop cleaning device with purge drainage. The water supply mechanism used in this patent technical solution pumps and sprays clean water from the water storage chamber to clean the mop. This ensures that the clean water cleans the flat mop cleaning pad and that the dirty water is integrated into the dirty water chamber. However, this water supply mechanism uses a rack gear to transmit power to the pump. This requires the addition of a rack gear, making the transmission structure relatively complex and prone to malfunction. Invention patent publication number CN217987499U also has a similar technical defect, and the problem of a complex transmission mechanism and prone to malfunction cannot be avoided.

[0004] To overcome the above problems, a mop bucket pumping cleaning mechanism is needed. Summary of the Invention [Problem to be solved by the invention]

[0005] The purpose of this invention is to provide a mop bucket pumping cleaning mechanism that uses the conventional limit roller directly as a power source to drive the pump to pump water, thereby simplifying the structure and reducing the failure rate. [Means for solving the problem]

[0006] To solve the above technical problems, the present invention adopts the following technical solutions:

[0007] This device is a mop bucket pumping cleaning mechanism installed in the cleaning nozzle of the mop bucket body, a cleaning nozzle bracket used to mount a limit roller and a cleaning assembly, and removably mounted below a top panel of the upper opening of the mop bucket body, the cleaning nozzle being molded into the top panel and the cleaning nozzle bracket, the limit roller providing a limit at its rear against a mop plate inserted into the cleaning nozzle, and the cleaning assembly spray cleaning against a cleaning pad in front of the mop plate; a pump installed in the fresh water chamber of the mop bucket body, the limit roller transmitting power to the pump through a transmission assembly, and the pump pumping water to the cleaning assembly.

[0008] Furthermore, the transmission assembly includes a link and a rocker arm, the central shaft of the rocker arm is coaxially and fixedly connected to the central shaft of the limit roller, the eccentric shaft head of the rocker arm is rotatably connected to the tip of the link, and the bottom end of the link is connected to the piston of the pump.

[0009] Additionally, a drain pipe from the pump extends upward and communicates with a water conduit in the top panel, which directs water to the cleaning assembly.

[0010] The cleaning assembly further includes a fresh water cover plate, and a fresh water reservoir tank is installed on the top panel opposite the limit roller, the drain outlet of the water conduit communicates with the fresh water reservoir tank, the fresh water cover plate is sealingly engaged with the fresh water reservoir tank, and a plurality of drain holes are opened at the tip of the fresh water cover plate facing the cleaning nozzle.

[0011] Furthermore, the fresh water cover plate is made of a transparent plastic plate.

[0012] Furthermore, the cleaning assembly further includes a bristle unit, the bristle unit being installed below the fresh water reservoir, and a brush of the bristle unit cleaning the cleaning pad of the mop plate.

[0013] Furthermore, the cleaning assembly further includes a sub-scraper, which is installed below and parallel to the bristle unit, and which semi-dewaters the cleaning pad of the mop plate.

[0014] Furthermore, the number of the limit rollers is two, and the two limit rollers are symmetrically installed on both sides of the small end of the cleaning nozzle, and the corresponding transmission assembly and pump are also two sets.

[0015] Furthermore, the limit roller is a rubber roller or has a rubber cover fitted on its outer surface, and a friction belt is installed corresponding to the contact position between the rear surface of the mop plate and the limit roller.

[0016] The present invention further discloses a mop bucket pumping cleaning mechanism, which employs the mop bucket pumping cleaning mechanism described in any one of the above claims to perform the cleaning work of the mop cleaning pad, and uses the limit roller on the cleaning nozzle as a power source to output power to the pump, which pumps water to spray and clean the cleaning pad of the mop plate. [Effects of the Invention]

[0017] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0018] The mop bucket pumping cleaning mechanism of this invention uses the limit roller as the driving power source for the pump, which limits the rolling of the mop plate while also realizing secondary use of the power. Compared to conventional technologies, this avoids the need for redundant installation of gear assemblies, simplifies the structure, and reduces the tool failure rate.

[0019] The rocker arm's central shaft is coaxially and fixedly connected to the limit roller's central shaft, simplifying the transmission structure and directly converting the rotation of the central shaft into the linear reciprocating motion of the piston, improving kinetic energy efficiency. The cantilever end of the eccentric shaft head is designed as a split half-shaft, facilitating the removal and installation of the link. The water channel and the clean water reservoir allow for smooth drainage of the pump's wastewater. The clean water cover plate seals the clean water reservoir and features a drainage hole at its front edge, allowing for cleaning with a cleaning pad. The clear plastic cover plate allows for intuitive observation of the flowing water. The brush section allows the mop plate's cleaning pad to reach a deep level of cleaning, removing embedded dirt and impurities. The sub-scraper, installed below the brush section, semi-dries the cleaning pad, removing dirty water and allowing it to absorb fresh water again during the next spray cycle, improving cleaning efficiency. The two transmission assemblies and pumps improve the pumping flow rate and ensure a sufficient amount of water for cleaning. The force on both sides of the back of the mop plate is balanced, preventing uneven movement and vertical up and down movement, preventing scraping against the bucket wall. The limit rollers are rubber rollers or fitted with rubber covers on their outer surfaces, increasing the friction between them and the back of the mop plate and ensuring smooth operation. The corresponding friction belts on the back of the mop plate further increase the friction with the limit rollers, preventing them from spinning freely.

[0020] The mop bucket pumping cleaning mechanism of this invention uses a friction wheel transmission to provide driving force for the pump, eliminating the need for separate racks and gears, simplifying the structure, preventing stuck gear failure, shortening the transmission chain, and reducing resistance during cleaning.

[0026] In one specific embodiment, as shown in FIGS. 1 to 7, the mop bucket pumping cleaning mechanism of the present invention is installed in the cleaning opening 103 of the mop bucket body 1; The cleaning sieve bracket 2 is used to mount the limit roller 6 and the cleaning assembly and is removably attached to the bottom of the top panel 4 of the top opening of the mop bucket body 1 with screws. A cleaning sieve 103 is molded into the top panel 4 and the cleaning sieve bracket 2. The top panel 4 is engaged with the top opening of the bucket body 1, and a scrubbing / drying sieve 104 is installed at one end of the top panel 4 away from the cleaning sieve 103. The limit roller 6 limits the mop plate 10 inserted into the cleaning sieve 103 at its back, adjusting the distance between the cleaning pad in front of the mop plate 10 and the cleaning assembly. Generally, all mop buckets require a limit wheel to be installed in the cleaning sieve 103; if there is no limit wheel, a limit protrusion block that abuts against the back of the mop plate 10 is required. The cleaning assembly includes the cleaning sieve bracket 2, which sprays and cleans the cleaning pad in front of the mop plate 10. and a pump 7 installed in the fresh water chamber 101 of the mop bucket body 1, wherein the limit roller 6 transmits power to the pump 7 through a transmission assembly, and the pump 7 pumps water to the cleaning assembly.

[0027] The limit roller 6 is used as the driving power source for the pump 7, which limits the rolling of the mop plate 10 while simultaneously realizing secondary use of power. Compared with conventional technologies, this avoids redundant installation of gear assemblies, simplifies the structure, and reduces the tool failure rate.

[0028] The existing mop bucket mold can be easily modified to produce the mop bucket with dirt and clean separation of this invention by simply using the existing limit wheel and adding the corresponding pump and transmission assembly, thereby reducing the investment cost of the production mold.

[0029] 3 to 6, the transmission assembly includes a link 8 and a rocker arm 9, the center shaft of which is coaxially and fixedly connected to the center shaft of the limit roller 6, and the two may be integral or directly heat-welded. The center shaft of the limit roller 6 is horizontally supported by the support seat of the cleaning nozzle bracket 2, and the lower support rib of the top panel 4 limits the center shaft of the limit roller 6 within the support seat. The eccentric shaft head 901 of the rocker arm 9 is rotatably connected to the tip of the link 8, the bottom end of which is connected to the piston of the pump 7, driving the piston to move back and forth linearly to perform pumping.

[0030] Specifically, as shown in FIG. 7, the cantilever end of the eccentric shaft head 901 is in the form of a split half shaft, with a retraction gap provided in the middle, which makes it easy to smoothly insert the shaft hole at the tip of the link 8.

[0031] Furthermore, the central shaft of the rocker arm 9 is coaxially and fixedly connected to the central shaft of the limit roller 6, thereby simplifying the transmission structure, directly converting the rotation of the central shaft into the linear reciprocating movement of the piston, and improving kinetic energy efficiency. Furthermore, the cantilever end of the eccentric shaft head 901 is in the form of a split half shaft, which makes it easy to remove and install the link 8.

[0032] In one specific embodiment of the present invention, as shown in Figures 4 and 5, the drain pipe 701 of the pump 7 extends upward and communicates with the water conduit 401 of the top panel 4, which directs water to the cleaning assembly.

[0033] Specifically, the cleaning assembly includes a fresh water cover plate 5, a fresh water reservoir tank is installed on the top panel 4 opposite the limit roller 6, the drain port of the water conduit 401 communicates with the fresh water reservoir tank, the fresh water cover plate 5 is sealed and engaged with the fresh water reservoir tank, and a plurality of drain holes 501 are opened at the tip of the fresh water cover plate 5 toward the cleaning opening 103. The plurality of drain holes 501 are opened at equal intervals along the front edge of the fresh water cover plate 5.

[0034] Specifically, the fresh water cover plate 5 is made of a transparent plastic plate material.

[0035] The installation of the water conduit 401 and the fresh water storage tank allows the water discharged from the pump 7 to be smoothly guided. The installation of the fresh water cover plate 5 seals the fresh water storage tank and forms a drainage hole 501 at the front edge, which can be cleaned by spraying a cleaning pad. The fresh water cover plate 5 is made of a transparent plastic plate, which allows the flowing water situation to be intuitively observed.

[0036] In a specific embodiment of the present invention, as shown in Figures 1, 2 and 5, the cleaning assembly further includes a bristle unit 3, which is installed below the fresh water reservoir and has brushes with stiff bristles arranged in a bundle, for cleaning the cleaning pad of the mop plate 10.

[0037] Specifically, the cleaning assembly further includes a sub-scraper, which is made of a hard plastic plate material and is installed parallel to and below the bristle unit 3, and semi-dewaters the cleaning pad of the mop plate 10. A water guide plate is installed at the drainage bottom end of the sub-scraper, which can guide dirty water to the dirty water chamber 102 below the mop bucket body 1.

[0038] The installation of the brush unit 3 allows for deep scraping and cleaning of the cleaning pad of the mop plate 10, removing embedded dirt and impurities. The sub-scraper installed below the brush unit 3 semi-dries the cleaning pad, removing dirty water and making it easier to re-absorb clean water the next time the mop is sprayed, improving cleaning efficiency.

[0039] In one specific embodiment of the present invention, as shown in Figures 3 to 6, the number of limit rollers 6 is two, and the two limit rollers 6 are symmetrically installed on both sides of the small end of the cleaning nozzle 103, and the corresponding transmission assembly and pump 7 are also two sets.

[0040] By installing two sets of the transmission assembly and pump 7, the pumping flow rate is improved and the amount of cleaning water is guaranteed, while the force on both sides of the back of the mop plate 10 is matched, so that there is no imbalance and the mop plate moves up and down vertically, and there is no scraping against the bucket wall.

[0041] In one embodiment of the present invention, as shown in Figures 3, 5, 6 and 8, the limit roller 6 is a rubber roller or has a rubber cover fitted on its outer surface, and is made of a wear-resistant and water-resistant rubber material. A friction belt 1001 is installed at the contact position between the back surface of the mop plate 10 and the limit roller 6.

[0042] Specifically, as shown in FIG. 8, the friction belt 1001 may be a knurled pattern belt with a concave-convex shape, or may be an attached sandpaper friction belt strip.

[0043] The limit roller 6 can be made of a rubber roller or fitted with a rubber cover on its outer surface, thereby increasing the frictional force between the limit roller 6 and the back surface of the mop plate 10, and further ensuring smooth operation of the limit roller 6. By installing a corresponding friction belt 1001 on the back surface of the mop plate 10, the frictional force with the limit roller 6 can be further increased, and the limit roller 6 can be prevented from spinning freely.

[0044] The mop bucket pumping cleaning mechanism of this invention operates as follows: After the mop plate 10 is erected, the mop to be cleaned is inserted into the cleaning nozzle 103, with the mop rod facing the small end of the cleaning nozzle 103, and the friction belts 1001 on the back of the mop plate 10 contact the limit rollers 6. As the mop plate 10 is inserted and pulled up and down, the two friction belts 1001 rotate the corresponding limit rollers 6, which in turn rotate the rocker arms 9. The eccentric head 901 pushes and pulls the tip of the link 8, and the bottom of the link 8 pushes and pulls the piston of the pump 7, driving the piston to move back and forth linearly to perform pumping. The pump 7 extracts fresh water from the fresh water chamber 101 and directs it to the cleaning assembly along the drain pipe 701 and the water guide pipe 401. At the same time, the fresh water reservoir is filled with fresh water, which is sprayed onto the cleaning pad moving up and down through the drain hole 501 at the tip of the fresh water cover plate 5, cleaning the cleaning pad. The brush unit 3 deeply scrapes the cleaning pad of the mop plate 10 to clean embedded dirt and impurities. The sub-scraper semi-dries and dehydrates the cleaning pad, removing dirty water so that the cleaning pad can re-adsorb fresh water for the next spray cleaning, improving cleaning efficiency.

[0045] In summary, the mop bucket pumping cleaning mechanism of this invention uses the limit roller 6 as the driving power source for the pump 7, which limits the rolling of the mop plate 10 while also realizing secondary power utilization, thereby avoiding the need for redundant gear assemblies compared to conventional technologies, simplifying the structure and reducing the tool failure rate. Furthermore, the center shaft of the rocker arm 9 is coaxially and fixedly connected to the center shaft of the limit roller 6, simplifying the transmission structure and directly converting the rotation of the center shaft into the linear reciprocating movement of the piston, improving kinetic energy efficiency. The cantilever end of the eccentric shaft head 901 is in the form of a split half shaft, facilitating the removal and installation of the link 8. The water channel 401 and the clean water reservoir allow for smooth drainage of the pump 7. The clean water cover plate 5 seals the clean water reservoir and has a drainage hole 501 at its front edge, allowing for spraying and cleaning of the cleaning pad. The cover plate 5 is made of a transparent plastic plate, allowing for intuitive observation of the flowing water. The brush unit 3 allows the cleaning pad of the mop plate 10 to perform deep cleaning and remove embedded dirt and impurities. The sub-scraper installed below the brush unit 3 semi-dries the cleaning pad, removing dirty water and facilitating re-adsorption of clean water during the next spray cleaning, improving cleaning efficiency. The installation of two sets of transmission assemblies and pumps 7 improves the pumping flow rate and ensures the amount of washing water, while aligning the forces on both sides of the back of the mop plate 10, preventing unevenness and vertical up and down movement, and preventing scraping against the bucket wall. The limit rollers 6 are rubber rollers or have rubber covers fitted on their outer surfaces to increase the friction between the limit rollers 6 and the back of the mop plate 10 and further ensure smooth operation of the limit rollers 6. The installation of a corresponding friction belt 1001 on the back of the mop plate 10 further increases the friction with the limit rollers 6 and prevents them from spinning freely.

[0046] The present invention further discloses a mop bucket pumping cleaning mechanism, which employs the mop bucket pumping cleaning mechanism of any of the above-mentioned embodiments to perform the cleaning work of the mop cleaning pad, and uses the limit roller on the cleaning nozzle as a power source to output power to the pump, which pumps water to spray and clean the cleaning pad of the mop plate.

[0047] The pump is driven by a friction wheel transmission, eliminating the need for separate racks and gears, simplifying the structure and preventing stuck gear failure. The transmission chain is also shorter, reducing resistance during cleaning.

[0048] Furthermore, the mop bucket in this invention is a mop bucket with separate cleaning and washing chambers, i.e., the washing chamber and the scrubbing and drying chambers are separated. The cleaning and scrubbing nozzles and the scrubbing and drying nozzles are centrally located on both ends of the top panel, which is consistent with traditional immersion mop buckets and upgrades the bucket to separate cleaning and washing while adapting to user working habits and gaining consumer recognition. The central clean water chamber separates the cleaning and scrubbing chambers to prevent interference between them, and a pump is installed nearby to facilitate pumping. The adapter bucket body can be inserted between the upper and lower bucket bodies to roughly filter the dirty water entering the dirty water chamber, preventing large blocks and long miscellaneous items from entering the dirty water chamber, facilitating sorting and preventing clogging.

[0049] The above-described embodiments are merely illustrative of the preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the design spirit of the present invention should fall within the scope of protection defined in the claims of the present invention.
