Description

Technical Field

[0001] The invention relates to the technical field of cleaning tools, and in particular to a mop bucket water pump cleaning mechanism and a working method thereof. Background Art

[0002] For the cleaning and dehydration of flat mops on the market, most of them use the clean water area to soak the mop for cleaning, and then set a water squeezing device and a water scraper in the bucket for dehydration. The dirt on the mop head is removed while squeezing and scraping the water, and the sewage flows back to the clean water area. This mop has a simple structure and is economical and practical. However, the flat mops currently on the market are soaked and cleaned in the clean water area, and the water cannot guarantee thorough cleaning. After repeated use, it will become sewage and cannot effectively clean the mop.

[0003] At present, there are also many mop buckets with clean and dirty separation. They no longer use immersion cleaning, but use pumping water to spray and clean the cleaning pad of the flat mop. The utility model patent with announcement number CN217610946U discloses a mop cleaning device with clean and dirty drainage. The water supply mechanism used in the patented technical solution pumps clean water in the water storage chamber to spray and clean the mop. It can ensure that clean water cleans the cleaning pad of the flat mop, and the sewage flows into the sewage chamber. However, the water supply mechanism uses gear racks to transmit power to the water pump. Gear racks need to be additionally arranged, and the transmission structure is relatively complicated and prone to failure. The utility model patent with announcement number CN217987499U also has the same technical defects and cannot avoid the problem of complex transmission mechanism and prone to failure.

[0004] In order to overcome the above problems, a mop bucket water pump cleaning mechanism and a working method thereof are needed. Summary of the invention

[0005] The purpose of the present invention is to provide a mop bucket water pump cleaning mechanism and a working method thereof, which directly utilizes the original limiting roller as a power source to drive the water pump to pump water, thereby simplifying the structure and reducing the failure rate.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] The present invention discloses a mop bucket water pump cleaning mechanism, which is arranged on a cleaning opening of a mop bucket body and comprises:

[0008] A cleaning mouth bracket is used to install a limiting roller and a cleaning component. The cleaning mouth bracket is detachably installed below the top panel of the top opening of the mop bucket body. The cleaning mouth is formed on the top panel and the cleaning mouth bracket. The limiting roller limits the back of the mop plate inserted into the cleaning mouth, and the cleaning component sprays and cleans the cleaning pad on the front of the mop plate.

[0009] A water pump is arranged in the clean water cavity of the mop bucket body. The limiting roller transmits power to the water pump through the transmission component, and the water pump pumps water to the cleaning component.

[0010] Furthermore, the transmission assembly includes a connecting rod and a rocker arm, the center axis of the rocker arm is coaxially fixedly connected to the center axis of the limiting roller; the eccentric shaft head of the rocker arm is rotatably connected to the top end of the connecting rod, and the bottom end of the connecting rod is connected to the piston of the water pump.

[0011] Furthermore, the water outlet pipe of the water pump extends upward and is connected to the water channel of the top panel, and the water channel guides water to the cleaning component.

[0012] Furthermore, the cleaning component includes a clean water cover plate, the top panel is provided with a clean water storage tank on the opposite side of the limiting roller, the water outlet port of the water guide channel is connected to the clean water storage tank, the clean water cover plate is tightly buckled on the clean water storage tank, and the clean water cover plate is provided with a plurality of water outlet holes at the front end toward the cleaning mouth.

[0013] Furthermore, the clean water cover plate is made of a transparent plastic plate.

[0014] Furthermore, the cleaning component also includes a brush bar, which is arranged below the clean water storage tank, and the brush of the brush bar cleans the cleaning pad of the mop flat plate.

[0015] Furthermore, the cleaning component also includes an auxiliary scraper, which is arranged in parallel below the brush strip, and the auxiliary scraper semi-dehydrates the cleaning pad of the mop flat plate.

[0016] Furthermore, the number of the limiting rollers is two, and the two limiting rollers are symmetrically arranged on both sides of the small port of the cleaning mouth, and the corresponding transmission assembly and the water pump are also two sets.

[0017] Furthermore, the limiting roller is a rubber wheel or the outer wheel surface is provided with a rubber cushion sleeve, and a friction belt is correspondingly provided at the contact position between the back side of the mop plate and the limiting roller.

[0018] The present invention also discloses a working method of a mop bucket water pump cleaning mechanism, which uses the mop bucket water pump cleaning mechanism described in any one of the above claims to perform a mop cleaning pad cleaning operation, and uses the limiting roller on the cleaning stroke as a power source to output power to a water pump to pump water and spray to clean the cleaning pad of the mop flat plate.

[0019] Compared with the prior art, the beneficial technical effects of the present invention are:

[0020] The mop bucket water pump cleaning mechanism of the present invention uses a limiting roller as a driving power source for the water pump, and realizes secondary utilization of power while limiting the rolling position of the mop plate. Compared with the prior art, it avoids repeated arrangement of gear components, simplifies the structure, and reduces the failure rate of the tool.

[0021] In addition, the central axis of the rocker arm is coaxially fixedly connected with the central axis of the limiting roller, which simplifies the transmission structure, directly converts the rotation of the central axis into the reciprocating linear motion of the piston, and improves the kinetic energy efficiency; by making the cantilever end of the eccentric shaft head into a half-shaft form, it is easy to disassemble and install the connecting rod. Through the setting of the water guide channel and the clean water storage tank, the water output of the water pump can be smoothly guided; through the setting of the clean water cover plate, the clean water storage tank can be closed and a water outlet hole can be formed on the front edge to spray on the cleaning pad for washing; the clean water cover plate is made of transparent plastic plate material, and the water flow condition can be observed intuitively. Through the setting of the brush bar, the mop flat cleaning pad can be deeply scraped and cleaned to clean out the buried stains and impurities; by adding the auxiliary scraper under the brush bar, the auxiliary scraper semi-dehydrates the cleaning pad, that is, semi-dry dehydration, which can remove sewage and facilitate the re-absorption of clean water during the next spray cleaning, thereby improving the cleaning efficiency. By setting two sets of the transmission components and water pumps, on the one hand, the pump water flow rate is increased to ensure the amount of water used for cleaning, and on the other hand, the back side of the mop plate is subjected to the same force on both sides, so that it will not deflect, and it will reciprocate vertically up and down without scratching the barrel wall. By using a rubber wheel or a rubber pad on the outer wheel surface of the limiting roller, the friction between the limiting roller and the back side of the mop plate can be increased, thereby ensuring that the limiting roller is driven smoothly; by setting a corresponding friction belt on the back side of the mop plate, the friction with the limiting roller can be further increased to avoid the limiting roller from slipping.

[0022] The working method of the mop bucket water pump cleaning mechanism of the present invention adopts a friction wheel transmission mode to provide driving force for the water pump, and no rack and gear need to be additionally provided. The structure is simple and gear jamming failure is avoided. Meanwhile, the short transmission chain also reduces the resistance during cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The core of the present invention is to provide a mop bucket water pump cleaning mechanism and a working method thereof, which directly utilizes the original limiting roller as a power source to drive the water pump to pump water, thereby simplifying the structure and reducing the failure rate.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Figure 7 for Figure 6 A schematic diagram of the partial enlarged structure of the middle I part; Figure 8 The present invention is a schematic diagram of the three-dimensional structure of a mop flat plate used with the mop bucket water pump cleaning mechanism.

[0038] In a specific embodiment, Figures 1 to 7 As shown, the mop bucket water pump cleaning mechanism of the present invention is arranged on the cleaning opening 103 of the mop bucket body 1, and includes:

[0039] The cleaning mouth bracket 2 is used to install the limiting roller 6 and the cleaning component. The cleaning mouth bracket 2 is detachably installed under the top panel 4 of the top opening of the mop bucket body 1 by screws. The cleaning mouth 103 is formed on the top panel 4 and the cleaning mouth bracket 2; the top panel 4 is buckled on the top opening of the bucket body 1, and the top panel 4 is provided with a scraping mouth 104 at the end away from the cleaning mouth 103. The limiting roller 6 limits the back of the mop plate 10 inserted into the cleaning mouth 103, so that the cleaning pad on the front of the mop plate 10 is at an appropriate distance from the cleaning component. Generally speaking, all mop buckets need to be provided with a limiting wheel on the cleaning mouth 103. If there is no limiting wheel, a limiting protrusion needs to be provided to abut against the back of the mop plate 10. The cleaning component sprays and cleans the cleaning pad on the front of the mop plate 10.

[0040] The water pump 7 is arranged in the clean water cavity 101 of the mop bucket body 1. The limiting roller 6 transmits power to the water pump 7 through the transmission component, and the water pump 7 pumps water to the cleaning component.

[0041] By using the limiting roller 6 as the driving power source of the water pump 7, secondary utilization of power is achieved while rolling and limiting the mop plate 10. Compared with the prior art, repeated setting of gear components is avoided, the structure is simplified, and the failure rate of the tool is reduced.

[0042] The clean and dirty separation mop bucket of the present invention can be produced by simply modifying the existing mop bucket mold. The original limiting wheel can be used to add a corresponding water pump and transmission assembly, thereby reducing the investment cost of the production mold.

[0043] In a specific embodiment of the present invention, Figures 3 to 6 As shown, the transmission assembly includes a connecting rod 8 and a rocker arm 9. The middle axis of the rocker arm 9 is coaxially fixedly connected with the middle axis of the limiting roller 6. The two can be integrated or directly hot-melt welded together. The middle axis of the limiting roller 6 is horizontally erected through the support seat of the cleaning bracket 2, and the lower support ribs of the top panel 4 limit the middle axis of the limiting roller 6 in 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, and 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 pump water.

[0044] Specifically, if Figure 7 As shown, the cantilever end of the eccentric shaft head 901 is in the form of a split half shaft, with a clearance gap in the middle to facilitate smooth installation of the shaft hole at the top end of the connecting rod 8.

[0045] The central axis of the rocker arm 9 is coaxially fixedly connected with the central axis of the limiting roller 6, thereby simplifying the transmission structure, directly converting the rotation of the central axis into the reciprocating linear motion of the piston, and improving the kinetic energy efficiency; by making the cantilever end of the eccentric shaft head 901 into a split half-shaft form, it is convenient to disassemble and install the connecting rod 8.

[0046] In a specific embodiment of the present invention, Figure 4 and Figure 5 As shown, the water outlet pipe 701 of the water pump 7 extends upward and is connected to the water channel 401 of the top panel 4, and the water channel 401 guides water to the cleaning component.

[0047] Specifically, the cleaning assembly includes a clean water cover plate 5, a clean water tank is provided on the top panel 4 on the opposite side of the limiting roller 6, a water outlet port of the water guide channel 401 is connected to the clean water tank, the clean water cover plate 5 is tightly buckled on the clean water tank, and a plurality of water outlet holes 501 are opened at the front end of the clean water cover plate 5 toward the cleaning mouth 103. The plurality of water outlet holes 501 are opened at equal intervals along the front edge of the clean water cover plate 5.

[0048] Specifically, the clean water cover plate 5 is made of a transparent plastic plate.

[0049] By setting the water conduit 401 and the clean water storage tank, the water output of the water pump 7 can be smoothly guided; by setting the clean water cover plate 5, the clean water storage tank can be closed and a water outlet hole 501 can be formed on the front edge to spray the water onto the cleaning pad for flushing; the clean water cover plate 5 is made of transparent plastic plate material, so that the water flow condition can be observed intuitively.

[0050] In a specific embodiment of the present invention, Figure 1 , Figure 2 and Figure 5As shown, the cleaning assembly further comprises a brush strip 3, which is arranged below the clean water tank, and the brush of the brush strip 3 is a bundle of hard bristles. The brush of the brush strip 3 cleans the cleaning pad of the mop flat plate 10.

[0051] Specifically, the cleaning assembly further includes an auxiliary scraper, which is made of a hard plastic plate. The auxiliary scraper is arranged parallel to the lower side of the brush bar 3, and the auxiliary scraper semi-dehydrates the cleaning pad of the mop flat plate 10. A water guide plate is arranged at the lower end of the auxiliary scraper to guide the sewage to the sewage chamber 102 below the mop bucket body 1.

[0052] By setting the brush strip 3, the cleaning pad of the mop flat plate 10 can be deeply scraped and cleaned to remove buried stains and impurities; by adding the auxiliary scraper under the brush strip 3, the auxiliary scraper can semi-dehydrate the cleaning pad, that is, semi-dry dehydration, which can remove dirty water and facilitate the re-absorption of clean water during the next spray cleaning, thereby improving the cleaning efficiency.

[0053] In a specific embodiment of the present invention, Figures 3 to 6 As shown, there are two limit rollers 6, which are symmetrically arranged on both sides of the small end of the cleaning mouth 103, and the corresponding transmission components and water pumps 7 are also two sets.

[0054] By providing two sets of the transmission components and water pump 7, on the one hand, the pump water flow rate is increased to ensure the amount of water for cleaning, and on the other hand, the back sides of the mop plate 10 are subjected to the same force without deflection, and the mop plate 10 can reciprocate vertically without scratching the barrel wall.

[0055] In a specific embodiment of the present invention, Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, the limiting roller 6 is a rubber wheel or a rubber pad sleeve is provided on the outer wheel surface, and is made of wear-resistant and water-resistant rubber material. A friction belt 1001 is provided at the contact position between the back of the mop plate 10 and the limiting roller 6.

[0056] Specifically, if Figure 8 As shown, the friction belt 1001 can be a belt with convex and concave knurled patterns, or it can be a pasted sandpaper friction belt strip.

[0057] By using a rubber wheel or a rubber pad cover on the outer 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 providing a corresponding friction belt 1001 on the back of the mop plate 10, the friction with the limiting roller 6 can be further increased to avoid the limiting roller 6 slipping.

[0058] The working principle of the mop bucket water pump cleaning mechanism of the present invention is as follows: the mop that needs to be cleaned will stand up the mop flat plate 10 and insert it into the cleaning groove 103. Note that the mop rod is facing the small end of the cleaning groove 103, and the friction belt 1001 on the back of the mop flat plate 10 is in contact with the limit roller 6. During the process of the mop flat plate 10 being inserted and pulled out up and down, the two friction belts 1001 respectively drive the corresponding limit rollers 6 to rotate, the limit rollers 6 drive the rocker arm 9 to rotate, the eccentric shaft head 901 pushes and pulls the top of the connecting rod 8, and the bottom of the connecting rod 8 pushes and pulls the piston of the water pump 7, driving the piston to reciprocate and linearly move to pump water. The water pump 7 extracts the clean water in the clean water chamber 101 and guides the water to the cleaning component along the outlet pipe 701 and the water 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 outlet hole 501 at the front end of the clean water cover plate 5 to rinse the cleaning pad. The brush strip 3 performs deep scraping and cleaning on the mop flat plate 10 cleaning pad to remove buried dirt and impurities. The auxiliary scraper performs semi-dry dehydration on the cleaning pad to remove sewage, so that the cleaning pad can re-absorb clean water during the next spray cleaning, thereby improving the cleaning efficiency.

[0059] In summary, the mop bucket water pump cleaning mechanism of the present invention uses the limiting roller 6 as the driving power source of the water pump 7, realizes the secondary utilization of power while rolling and limiting the mop flat plate 10, avoids the repeated setting of the gear assembly compared with the prior art, simplifies the structure, and reduces the failure rate of the tool. In addition, the central axis of the rocker arm 9 is coaxially fixedly connected with the central axis of the limiting roller 6, simplifies the transmission structure, directly converts the rotation of the central axis into the reciprocating linear motion of the piston, and improves the kinetic energy efficiency; by making the cantilever end of the eccentric shaft head 901 into a half-shaft form, it is convenient to disassemble and install the connecting rod 8. Through the setting of the water guide 401 and the clean water storage tank, the water output of the water pump 7 can be smoothly guided; through the setting of the clean water cover plate 5, the clean water storage tank can be closed and the water outlet hole 501 can be formed on the front edge to spray on the cleaning pad for washing; the clean water cover plate 5 is made of transparent plastic plate material, and the water flow condition can be observed intuitively. By setting the brush strip 3, the cleaning pad of the mop flat plate 10 can be deeply scraped and cleaned to remove the buried stains and impurities; by adding the auxiliary scraper below the brush strip 3, the auxiliary scraper semi-dehydrates the cleaning pad, that is, semi-dry dehydration, and can remove the sewage, which is convenient for re-adsorbing clean water during the next spray cleaning, thereby improving the cleaning efficiency. By setting two sets of the transmission components and water pumps 7, on the one hand, the pump water flow is increased to ensure the amount of water for cleaning, and on the other hand, the back sides of the mop flat plate 10 are subjected to the same force, will not deflect, and will reciprocate vertically up and down without scraping against the barrel wall. By using a rubber wheel or a rubber pad sleeve on the outer wheel surface of the limiting roller 6, the friction between the limiting roller 6 and the back of the mop flat plate 10 can be increased, thereby ensuring that the limiting roller 6 is driven smoothly; by setting a corresponding friction belt 1001 on the back of the mop flat plate 10, the friction with the limiting roller 6 can be further increased to avoid the limit roller 6 slipping.

[0060] The present invention also discloses a working method of a mop bucket water pump cleaning mechanism, which uses the mop bucket water pump cleaning mechanism in any of the above embodiments to perform a mop cleaning pad cleaning operation, and uses the limiting roller on the cleaning stroke as a power source to output power to a water pump to pump water and spray to clean the cleaning pad of the mop flat plate.

[0061] The friction wheel transmission method is used to provide driving force for the water pump. There is no need to set up racks and gears separately. The structure is simple and the gear jamming failure is avoided. At the same time, the short transmission chain also reduces the resistance during cleaning.

[0062] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.
