Description

Technical Field

[0001] This application relates to the technical field of floor cleaning pads, and in particular to a floor cleaning pad for cleaning floor dirt. Background Technology

[0002] A floor scrubbing plate is an accessory for high-pressure washers, specifically designed for floor cleaning. It efficiently removes stains from floors using rotating nozzles carrying high-pressure water, and is particularly suitable for flat, hard surfaces. Its structure includes a base housing, a mounting hole on the top surface of the base housing that extends through it, a connecting housing mounted on the top surface of the base housing and covering the mounting hole, a connecting pipe located inside the base housing and inserted into the mounting hole, a docking pipe mounted on and connected to the connecting housing, a spray pipe fixedly connected to the bottom of the connecting pipe, and nozzles fixedly mounted at both ends of the spray pipe with the spray ends facing downwards. The washing machine is connected via the docking pipe, and water is injected into the docking pipe. The water flows through the connecting housing into the connecting pipe, then through the connecting pipe into the spray pipe, and finally out through the nozzles. The water flow from the nozzles creates a reaction force on both ends of the spray pipe, causing the spray pipe to rotate at high speed for efficient cleaning of the floor.

[0003] However, there is a technical problem in the existing technology. In order to make the floor scrubbing tray easy to move, casters are usually installed on the outside of the floor scrubbing tray. Although the casters make the floor scrubbing tray easy to move, they also result in a certain gap between the bottom of the floor scrubbing tray and the ground. This gap causes the water sprayed from the nozzle to spill out after hitting the ground and splash onto the user's legs. In order to solve this technical problem, the existing technology has set a brush on the edge of the bottom of the floor scrubbing tray. The brush can block the water flow while cleaning the ground.

[0004] However, when using existing floor scrubbing devices to clean surfaces with walls, such as residential houses or fenced yards, the water flow from the scrubbing device is vertically downward, causing stains to spread outward from the scrubbing device. This means that when the scrubbing device is cleaning near a corner, the stains are pushed into the corner and accumulate there. The corner space is narrow, making the stains very difficult to clean. Furthermore, due to space limitations, the scrubbing device cannot move further into the corner, thus failing to clean the stains in the corner. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this application is to provide a floor cleaning pad for cleaning stains in corners.

[0006] The above-mentioned objective of this application is achieved through the following technical solution: a floor cleaning platform, comprising a platform shell, an installation hole formed on the top surface of the platform shell and penetrating the platform shell, a connecting shell installed on the top surface of the platform shell and covering the installation hole, a connecting pipe located inside the platform shell and inserted into the installation hole and rotatably connected to the platform shell, a docking pipe installed on the connecting shell and communicating with the connecting shell, a water spray pipe fixedly connected to the bottom end of the connecting pipe, a nozzle fixedly installed at both ends of the water spray pipe with the spray end facing downwards, and universal wheels fixedly installed on the outside of the platform shell. The end faces of both ends of the water spray pipe are provided with connecting threaded holes communicating with the internal space of the water spray pipe. A wall cleaning device connected to the water spray pipe through the connecting threaded holes is installed on the inner wall of the platform shell. A brush for blocking water flow is installed on half of the area of ​​the bottom edge of the platform shell.

[0007] Furthermore, the wall cleaning device includes a fixed pipe installed inside the chassis housing and facing the water spray pipe, a threaded pipe threadedly connected inside the fixed pipe, a transfer pipe fixedly installed below the end of the fixed pipe away from the water spray pipe and connected to the fixed pipe, and a wall cleaning pipe fixedly installed on the bottom end of the transfer pipe and connected to the transfer pipe. The wall cleaning pipe is horizontally arranged on the transfer pipe, and a water spray head is provided at the end facing out of the chassis housing.

[0008] By adopting the above technical solution, under normal circumstances, the user seals the threaded holes at both ends of the water spray pipe with bolts. The user then only needs to connect the cleaning machine through the connecting pipe to allow the floor cleaning pad to clean the floor. After cleaning the areas away from the wall, the user can unscrew the bolts and then tighten the threaded pipe to connect it to the water spray pipe. The user should align the half of the floor cleaning pad housing without the brushes with the wall or corner, and then start the cleaning machine. The machine pumps water into the connecting pipe, and the water flows through the connecting housing into the connecting pipe, and then through the connecting pipe into the water spray pipe. As the water flows out through the nozzle, it passes through the threaded pipe into the transfer pipe, and finally flows into the wall cleaning pipe and is sprayed out through the nozzle. The water jet from the nozzle directly impacts the wall or corner, thus cleaning the stains on the wall and corners and preventing stains from accumulating in the corners. This allows users to clean the areas that need cleaning more thoroughly. By setting the brush to occupy half the area of ​​the bottom edge of the chassis shell, users can avoid water splashing on them by pointing the side with the brush towards them. The side without the brush is also convenient for the nozzle to clean the wall and corners.

[0009] Furthermore, a rotating structure is provided on the inner wall of the chassis shell, and the wall cleaning device is installed on the chassis shell through the rotating structure.

[0010] Furthermore, the rotating structure includes an annular groove formed on the inner wall inside the chassis housing, a mounting slider slidably inserted into the annular groove, and the fixing tube is fixedly connected to the mounting slider.

[0011] While the wall cleaning device allows users to clean more comprehensively the areas that need cleaning, it also restricts the rotation of the water spray pipe during the cleaning process. This means that the wall cleaning device and the nozzle can only clean areas along the same straight line as the water spray pipe, greatly reducing the cleaning efficiency of the floor scrubber. The rotating structure solves this problem. By rotating the structure, the wall cleaning device can rotate along the annular groove with the mounting slider. This allows the reaction force of the nozzle to drive the water spray pipe to rotate, ensuring that the floor scrubber can clean the walls and corners without affecting the rotation of the water spray pipe, thus greatly increasing the cleaning efficiency of the floor scrubber.

[0012] Furthermore, a valve is provided in the middle of the threaded pipe.

[0013] While the wall cleaning device allows users to clean more comprehensively the areas that need cleaning, the previous method of connecting the threaded pipe to the water spray pipe was inconvenient. Users had to unscrew the bolts blocking the threaded holes at both ends of the water spray pipe before connecting it. However, with the valve and rotating mechanism, users can connect the threaded pipe directly to the water spray pipe while the floor is in normal operation, without needing to block the threaded holes. Simply closing the valve prevents water from flowing into the wall cleaning pipe. Furthermore, the rotating mechanism ensures that the wall cleaning device connected to the water spray pipe does not affect the floor cleaning effect, as the water spray pipe is not restricted by the device and can be rotated normally by the reaction force of the nozzle. When cleaning walls or corners, users simply need to open the valve and align the non-brush side of the floor casing with the wall or corner, making the floor cleaning system much more convenient.

[0014] Furthermore, a barrier structure is provided below the annular groove.

[0015] Furthermore, the blocking structure includes an annular intercepting groove located inside the chassis housing, an annular intercepting ring rotatably inserted into the annular intercepting groove, and multiple intercepting brushes fixedly disposed on the bottom edge of the annular connecting ring, the multiple intercepting brushes occupying half of the area on the bottom edge of the annular connecting ring.

[0016] While the brush design allows users to protect themselves and facilitates the cleaning of walls and corners with the spray nozzles, in actual use, when the user uses the floor scrubber away from walls or corners, the strong water flow required for cleaning stains causes water to splash very far from the side not blocked by the brushes. Sometimes, if the user is not careful, the water may splash onto other people or objects in the yard or room that cannot be wetted (such as paper items or appliances). However, if the brushes were installed on the entire bottom surface of the floor scrubber casing, it would restrict the spray nozzles' ability to clean walls and corners. The obstruction structure solves this problem. One technical issue is addressed by the barrier structure. When cleaning the floor, rotating the ring-shaped barrier allows the barrier brush to completely block the bottom surface of the chassis, preventing water from splashing out. When cleaning walls and corners, rotating the ring-shaped barrier overlaps the barrier brush, exposing half of the bottom surface of the chassis. This allows the spray nozzles to clean the walls and corners without obstruction. Because the exposed space is always aimed at the walls and corners, water will not splash onto other people or objects in the yard or room that should not be wetted, further enhancing the user experience of using the floor cleaning system.

[0017] Furthermore, the outer side of the chassis housing is provided with a connecting structure for mounting casters.

[0018] Furthermore, the connection structure includes a connecting screw hole on the outside of the chassis housing, a connecting plate on the outside of the chassis housing, a connecting bolt located at the upper end of the connecting plate, passing through the connecting plate and threaded to the chassis housing through the connecting screw hole, and a mounting plate fixedly disposed at the lower end of the connecting plate for mounting a caster wheel, wherein the caster wheel is mounted on the mounting plate.

[0019] By adopting the above technical solution and setting the connection structure, users can flip the floor scrubber when cleaning objects on the bottom surface (such as the chassis of a car), then unscrew the connecting bolts, rotate the connecting plate, and make the casters flip with the floor scrubber. Then, screw the connecting bolts in to fix the connecting plate, so that the user's nozzles spray water upwards, thereby enabling the user to clean the objects on the bottom surface and making the cleaning effect of the floor scrubber more comprehensive.

[0020] Furthermore, both the brush and the intercepting brush are made of nylon material.

[0021] By adopting the above technical solution, the brush and intercepting brush made of nylon material have good impact resistance and good moisture absorption rate, which can block water flow to the maximum extent.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The wall cleaning device allows users to spray water onto the wall or corners to clean stains and prevent them from accumulating in the corners, enabling users to clean the areas that need cleaning more thoroughly.

[0024] 2. By designing a rotating structure, the wall cleaning device can rotate along the annular groove with the mounting slider. This allows the reaction force of the nozzle to drive the water spray pipe to rotate, ensuring that the floor cleaning pan can clean the walls and corners without affecting the rotation of the water spray pipe, thus greatly increasing the cleaning efficiency of the floor cleaning pan.

[0025] 3. The valve and rotating mechanism allow users to easily connect the threaded pipe to the water spray pipe while the floor scrubber is in normal operation. There's no need to block the threaded hole with bolts; simply closing the valve prevents water from flowing into the wall cleaning pipe. Because of the rotating mechanism, the wall cleaning device connected to the water spray pipe doesn't affect the floor cleaning effect. The water spray pipe isn't restricted by the wall cleaning device and can rotate normally due to the reaction force of the nozzles. When cleaning walls or corners, simply open the valve to align the part of the floor scrubber housing not blocked by the brush with the wall or corner, making the floor scrubber more convenient to use.

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] Example, refer to Figure 1 , Figure 2 , Figure 3 A floor cleaning platform includes a chassis shell 1, a mounting hole on the top surface of the chassis shell 1 and penetrating the chassis shell 1, a connecting shell 10 mounted on the top surface of the chassis shell 1 and covering the mounting hole, a connecting pipe 11 located inside the chassis shell 1 and inserted into the mounting hole and rotatably connected to the chassis shell 1, a docking pipe 12 mounted on the connecting shell 10 and communicating with the connecting shell 10, a water spray pipe 13 fixedly connected to the bottom end of the connecting pipe 11, spray nozzles 14 fixedly mounted on both ends of the water spray pipe 13 with the spray ends facing downwards, and casters 15 fixedly mounted on the outside of the chassis shell 1. Connecting threads communicating with the internal space of the water spray pipe 13 are provided on the end faces of both ends of the water spray pipe 13. A wall cleaning device 2 is installed on the inner wall of the chassis housing 1, which is connected to the water spray pipe 13 via a threaded connection hole. A brush 16 for blocking water flow is installed on half of the bottom edge of the chassis housing 1. The wall cleaning device 2 includes a fixed pipe 20 installed inside the chassis housing 1 and facing the water spray pipe 13; a threaded pipe 21 threaded into the fixed pipe 20; a transfer pipe 22 fixedly positioned below the end of the fixed pipe 20 away from the water spray pipe 13 and connected to the fixed pipe 20; and a wall cleaning pipe 23 fixedly positioned at the bottom end of the transfer pipe 22 and connected to the transfer pipe 22. The wall cleaning pipe 23 is horizontally positioned on the transfer pipe 22, and a water spray head 24 is provided at the end facing outwards from the chassis housing 1 (see reference). Figure 4 The chassis shell 1 is a circular shell, and the bottom surface has an installation port that passes through the chassis shell 1.

[0034] Under normal conditions, the user seals the threaded holes at both ends of the water spray pipe 13 with bolts. The user then simply connects the cleaning machine to the connecting pipe 12 to clean the floor. After cleaning the areas away from the wall, the user unscrews the bolts and then tightens the threaded pipe 21 to connect it to the water spray pipe 13. The user aligns the half of the floor housing 1 without the brush 16 with the wall or corner, then starts the cleaning machine. The machine pumps water into the connecting pipe 12, which flows through the connecting housing 10 to the connecting pipe 11, and then through the connecting pipe 11 to the water spray pipe 13. The water then flows through… As the water sprays from the nozzle 14, it flows through the threaded pipe 21 into the transfer pipe 22, and finally into the wall cleaning pipe 23 before being sprayed out through the nozzle 24. The water sprayed from the nozzle 24 directly impacts the wall or corner, thereby cleaning stains on the wall and corners and preventing stains from accumulating in the corners. This allows users to clean the areas that need cleaning more comprehensively. Furthermore, by setting the brush 16 to occupy half the area of ​​the bottom edge of the chassis housing 1, users can prevent water from splashing onto them by aligning the side of the chassis housing 1 with the brush 16 with them. The side without the brush 16 is also convenient for the nozzle 24 to clean the wall and corners.

[0035] Although the wall cleaning device 2 allows users to clean the area more comprehensively, it also restricts the rotation of the water spray pipe 13 during the cleaning process. This means that the wall cleaning device 2 and the nozzle 14 can only clean areas along the same straight line as the water spray pipe 13, greatly reducing the cleaning efficiency of the floor scrubber. To solve this technical problem, refer to... Figure 3 In this embodiment, a rotating structure 3 is provided on the inner wall of the chassis housing 1. The wall cleaning device 2 is installed on the chassis housing 1 through the rotating structure 3. The rotating structure 3 includes an annular groove 30 opened on the inner wall of the chassis housing 1, and a mounting slider 31 slidably inserted into the annular groove 30. The fixing tube 20 is fixedly connected to the mounting slider 31. The mounting slider 31 can be installed in the annular groove 30 by magnetic attraction or snap-fit. For magnetic attraction, a magnet is fixedly set on the end face of the mounting slider 31. For snap-fit, snap-fit ​​grooves are opened on the upper and lower sides of the annular groove 30. Snap-fit ​​pieces are also set on the upper and lower sides of the mounting slider 31. The mounting slider 31 can be installed in the annular groove 30 by inserting the snap-fit ​​pieces into the snap-fit ​​grooves.

[0036] By rotating the structure 3, the wall cleaning device 2 can rotate along the annular groove 30 with the mounting slider 31. This allows the reaction force of the nozzle 14 to drive the water spray pipe 13 to rotate, so that the floor cleaning pan can clean the wall and corners without affecting the rotation of the water spray pipe 13, greatly increasing the cleaning efficiency of the floor cleaning pan.

[0037] Although the wall cleaning device 2 allows users to clean more comprehensively the areas that need cleaning, it is inconvenient for users to connect the threaded pipe 21 to the water spray pipe 13 before cleaning the walls and corners. This is because users must first unscrew the bolts blocking the threaded holes at both ends of the water spray pipe 13 before they can connect the threaded pipe 21 to the water spray pipe 13. To solve this technical problem, refer to... Figure 3 In this embodiment, a valve 4 is provided in the middle of the threaded pipe 21. The valve 4 can be a gate valve, a ball valve, or an electric valve 4.

[0038] With the cooperation of valve 4 and rotating structure 3, the user can rotate the threaded pipe 21 to connect to the water spray pipe 13 in the normal state of the floor cleaning pan without bolting the threaded hole. Simply close valve 4 to prevent water from flowing into the wall cleaning pipe 23. Because of the rotating structure 3, the wall cleaning device 2 connected to the water spray pipe 13 will not affect the user's floor cleaning effect. The water spray pipe 13 is not restricted by the wall cleaning device 2 and can be rotated normally by the reaction force of the nozzle 14. When the user needs to clean the wall and corners, simply turn on valve 4 so that the half of the base housing 1 without the brush 16 is aligned with the wall or corner, making it more convenient for the user to use the floor cleaning pan.

[0039] Although the brush 16 design allows users to protect themselves while facilitating the cleaning of walls and corners by the spray head 24, in actual use, when the user uses the floor scrubber away from walls or corners, the strong water flow required for cleaning stains causes the water not blocked by the brush 16 to splash very far. Sometimes, if the user is not careful, the water may splash onto other people or objects in the yard or room that cannot be wetted (such as paper items or appliances). However, if the brush 16 were installed on the entire bottom surface of the floor casing 1, it would limit the cleaning of walls and corners by the spray head 24. To solve this technical problem, refer to... Figure 3In this embodiment, a blocking structure 5 is provided below the annular groove 30. The blocking structure 5 includes an annular intercepting groove 50 located inside the chassis housing 1 in the annular groove 30, an annular intercepting ring 51 rotatably inserted into the annular intercepting groove 50, and a plurality of intercepting brushes 52 fixedly disposed on the bottom edge of the annular connecting ring. The plurality of intercepting brushes 52 occupy half of the area on the bottom edge of the annular connecting ring. The annular intercepting ring 51 can be installed in the annular intercepting groove 50 by magnetic attraction, snap-fit ​​or damping insertion.

[0040] With the barrier structure 5 in place, when the user cleans the floor, rotating the annular barrier ring 51 causes the barrier brush 52, in conjunction with the brush 16, to completely block the entire space on the bottom surface of the chassis housing 1, preventing water from splashing out of the chassis housing 1. When the user needs to clean the walls and corners, rotating the annular barrier ring 51 causes the barrier brush 52 to overlap with the brush 16 (see reference). Figure 4 The exposed space on the bottom of the chassis housing 1 allows the spray nozzle 24 to clean the walls and corners without obstruction. Because the exposed space is always aimed at the walls and corners during cleaning, water will not splash onto other people or objects in the yard or room that cannot be wetted, further improving the user experience of using the floor cleaning platform. Furthermore, by having the intercepting brush 52 overlap with the brush 16, the blocking effect of the space not exposed by the chassis housing 1 is further enhanced, further improving the waterproof effect of the chassis housing 1 when cleaning walls or corners.

[0041] Reference Figure 5 In this embodiment, the outer side of the chassis housing 1 is provided with a connecting structure 6 for mounting the universal wheels 15. The connecting structure 6 includes a connecting screw hole on the outer side of the chassis housing 1, a connecting plate 60 on the outer side of the chassis housing 1, a connecting bolt 61 located at the upper end of the connecting plate 60, passing through the connecting plate 60 and threaded to the chassis housing 1 through the connecting screw hole, and a mounting piece 62 fixedly disposed at the lower end of the connecting plate 60 for mounting the universal wheels 15. The universal wheels 15 are mounted on the mounting piece 62. Through the setting of the connecting structure 6, when cleaning objects on the bottom surface that need to be cleaned (such as the chassis of a car), the user can flip the floor washing platform, then unscrew the connecting bolt 61, rotate the connecting plate 60, so that the universal wheels 15 flip with the floor washing platform, and then screw in the connecting bolt 61 to fix the connecting plate 60, so that the user's spray nozzle 14 sprays water upward, thereby enabling the user to clean the objects on the bottom surface that need to be cleaned, making the cleaning effect of the floor washing platform more comprehensive.

[0042] In this embodiment, both the brush 16 and the intercepting brush 52 are made of nylon material. The brush 16 and the intercepting brush 52 made of nylon material have good impact resistance and good moisture absorption rate, which can block water flow to the maximum extent.

[0043] In other embodiments, polypropylene, steel wire, or metal wire may also be used. Although they can also block water flow, their impact resistance is weaker than that of nylon materials, and their service life is shorter than that of nylon materials.

[0044] Specific implementation process: When cleaning corners and walls, simply turn on valve 4, then rotate the annular interception ring 51 so that the interception brush 52 overlaps with the brush 16, exposing half of the space on the bottom of the chassis housing 1. Align the exposed space with the wall or wall surface, then connect the cleaning machine through the docking pipe 12, and start the cleaning machine. The cleaning machine pumps water into the docking pipe 12, and the water flows through the connecting housing 10 into the connecting pipe 11, and then through the connecting pipe 11 into the spray pipe 13. The water then sprays out through the nozzle 14, and flows through the threaded pipe 21 into the transfer pipe 22. Finally, the water flows into the wall cleaning pipe 23 and is sprayed out through the spray head 24. The water sprayed from the spray head 24 directly impacts the wall or corner, thereby cleaning the stains on the wall and corner and preventing stains from accumulating in the corner.

[0045] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
