Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a floor scrubber. Background Technology

[0002] A floor scrubber is a cleaning machine suitable for cleaning hard floors while simultaneously sucking up and removing wastewater from the ground. It has advantages such as being environmentally friendly, energy-saving, and highly efficient.

[0003] In related technologies, floor scrubbers include a roller brush and a machine body. The machine body is equipped with a clean water tank and a wastewater tank. Cleaning water from the clean water tank is sprayed onto the surface of the roller brush, which then cleans the surface by rolling along it. During cleaning operations, the floor scrubber pumps the wastewater generated into the wastewater tank. Over time, this increases the weight of the machine. Users need to exert considerable force to manually push the floor scrubber for extended periods, resulting in significant physical exertion, wasting time and effort, and negatively impacting the user experience. Summary of the Invention

Simultaneously, the bracket has a locked state where it is locked to the body assembly and an unlocked state where it can be separated from the body assembly. On one hand, when the bracket is in the locked state, the handle assembly can synchronously switch between an upright, tilted, or flat state with the body assembly and move under the drive of the floor brush assembly, thus meeting the user's cleaning needs for various cleaning environments. On the other hand, when the bracket is in the unlocked state, the handle assembly can rotate and separate from the body assembly, allowing the user to easily operate the floor brush assembly and body assembly along the surface being cleaned with less pushing force. This effectively reduces user fatigue and improves the user experience.

[0016] In some embodiments, the body assembly has a fixed state locked to the floor brush assembly and an active state that is movable relative to the floor brush assembly;

[0017] When the bracket is in the unlocked state and the body assembly is in the fixed state, the bracket can rotate relative to the body assembly and / or the floor brush assembly;

[0018] When the bracket is in the locked state and the body assembly is in the active state, the bracket can drive the body assembly to rotate relative to the floor brush assembly.

[0019] In some embodiments, the body assembly has a metal component, and the floor brush assembly has a magnetic component that corresponds to and cooperates with the metal component.

[0020] In some embodiments, the top of the floor brush assembly is higher than or equal to the top of the body assembly.

[0021] In some embodiments, the floor brush assembly includes a housing, a roller brush, and a booster wheel. The roller brush is rotatably disposed on the housing and partially protrudes from the housing, and the booster wheel is rotatably disposed on the housing and partially protrudes from the housing, so as to drive the floor brush assembly to move along the surface to be cleaned.

[0040] A floor scrubber is a cleaning machine suitable for cleaning hard floors while simultaneously sucking up and removing wastewater from the ground. It has advantages such as being environmentally friendly, energy-saving, and highly efficient.

[0041] In related technologies, floor scrubbers include a roller brush and a machine body. The machine body is equipped with a clean water tank and a wastewater tank. Cleaning water from the clean water tank is sprayed onto the surface of the roller brush, which then cleans the surface by rolling along it. During cleaning operations, the floor scrubber pumps the wastewater generated into the wastewater tank. Over time, this increases the weight of the machine. Users need to exert considerable force to manually push the floor scrubber for extended periods, resulting in significant physical exertion, wasting time and effort, and negatively impacting the user experience.

[0042] Addressing the issues of existing floor scrubbers being laborious to use and offering a poor user experience, this application provides one or more embodiments of a floor scrubber that rotatably connects the body assembly to the floor brush assembly, and the handle assembly's bracket is rotatably connected to the floor brush assembly. The bracket has both a locked state (locked to the body assembly) and an unlocked state (separated from the body assembly). On one hand, when the bracket is locked, the handle assembly can simultaneously switch between upright, tilted, and flat positions with the body assembly, moving under the influence of the floor brush assembly, thus meeting the user's cleaning needs for various environments. On the other hand, when the bracket is unlocked, the handle assembly can rotate and separate from the body assembly, allowing the user to easily operate the floor brush assembly and body assembly along the surface being cleaned with less pushing force. This significantly reduces user fatigue and improves the user experience.

[0043] See Figure 1 , Figure 2 and Figure 3 This application provides a floor scrubbing machine, which includes a floor brush assembly 100, a body assembly 200, and a handle assembly 300.

[0044] The body assembly 200 is rotatably connected to the floor brush assembly 100. The handle assembly 300 includes a bracket 310 and a handle 320 disposed on the bracket 310. The bracket 310 has a locked state that is locked to the body assembly 200 and an unlocked state that can be separated from the body assembly 200. The bracket 310 is rotatably connected to the floor brush assembly 100.

[0045] The bracket 310 can rotate and separate from the body assembly 200 when it is in the unlocked state, and the bracket 310 can drive the body assembly 200 to rotate relative to the brush assembly 100 when it is in the locked state.

[0046] It should be noted that in this application, the fuselage assembly 200 may include the fuselage 210 and functional components such as a sewage tank (not shown in the figure) disposed on the fuselage 210.

[0047] The floor brush assembly 100 may include a housing 120 and functional components such as a roller brush 130 and a suction structure 150 disposed on the housing 120. The floor scrubber may also include a clean water tank (not shown in the figure), which may be disposed on the housing 120 of the floor brush assembly 100 or on the body 210 of the body assembly 200. Water and detergent may be added to the clean water tank to form cleaning water.

[0048] It should also be noted that, in the handle assembly 300 of this application, the handle 320 refers to the component that the user manually holds and operates to push the entire floor scrubber along the surface being cleaned for cleaning operations. The handle 320 is connected to the body assembly 200 and the floor brush assembly 100 through the bracket 310. The handle 320 can be detached from the bracket 310 through interference fit, threaded connection, or other detachable methods to facilitate the disassembly, assembly, and replacement of the handle 320.

[0049] When the floor scrubber of this embodiment performs cleaning operations, the clean water tank sprays the cleaning water in it onto the surface of the roller brush 130. The user holds the handle 320 and pushes the entire floor scrubber along the surface to be cleaned. During this process, the roller brush 130 on the floor brush assembly 100 (which can be driven by a motor or other drive components to rotate around its own axis) rotates and rolls synchronously along the surface to be cleaned. The roller brush 130 continuously scrubs the surface to be cleaned. At the same time, during this process, the wastewater tank on the machine body assembly 200 will suck up the wastewater generated on the surface to be cleaned through the suction structure 150 of the floor brush assembly 100. In this way, the cleaning effect of scrubbing the surface to be cleaned is achieved.

[0050] In this application, the body assembly 200 is rotatably connected to the floor brush assembly 100, allowing the entire body assembly 200 to rotate relative to the floor brush assembly 100. The bracket 310 on the handle assembly 300 is rotatably connected to the floor brush assembly 100, allowing the handle 320 to rotate relative to the floor brush assembly 100 under the drive of the bracket 310, that is, the entire handle assembly 300 can rotate relative to the floor brush assembly 100.

[0051] The bracket 310 has a locked state that is locked to the body assembly 200 and an unlocked state that can be separated from the body assembly 200. When the bracket 310 is in the locked state, the handle assembly 300 is connected to the body assembly 200 and can rotate synchronously relative to the brush assembly 100. When the bracket 310 is in the unlocked state, the handle assembly 300 and the body assembly 200 can rotate independently relative to the brush assembly 100.

[0052] It is easy to understand that, through the above settings, when the bracket 310 is in the locked state, the user can hold the operating handle 320 to make the handle assembly 300 and the body assembly 200 rotate synchronously relative to the floor brush assembly 100, so that the handle assembly 300 and the body assembly 200 can switch between upright, tilted and flat states at the same time. By pushing the handle 320, the user can keep the handle assembly 300 and the body assembly 200 in an upright state (perpendicular to the surface being cleaned), a tilted state (tilted relative to the surface being cleaned), or a flat state (parallel relative to the surface being cleaned) synchronously, and move them under the action of the floor brush assembly 100, thereby meeting the user's cleaning needs for various cleaning environments.

[0053] When the bracket 310 is in the unlocked state, it can be detached from the body assembly 200, preventing the body assembly 200 from remaining stationary relative to the floor brush assembly 100 as the handle assembly 300 rotates. At this time, the user can hold the operating handle 320 and rotate the handle assembly 300 independently relative to the floor brush assembly 100, separating it from the body assembly 200. With this, the user can easily push the floor brush assembly 100 and the body assembly 200 along the surface being cleaned by applying less force while holding the handle assembly 300. This convenient operation effectively reduces user fatigue and enhances the user experience.

[0054] It is easy to understand that the floor scrubber of this embodiment, by rotatably connecting the body assembly 200 to the brush assembly 100 and the bracket 310 of the handle assembly 300 to the brush assembly 100, and simultaneously enabling the bracket 310 to have a locked state locked to the body assembly 200 and an unlocked state that can be separated from the body assembly 200, allows the handle assembly 300 to switch between an upright, tilted, or flat state synchronously with the body assembly 200 when the bracket 310 is in the locked state, and to move under the drive of the brush assembly 100, thereby meeting the user's cleaning needs for various cleaning environments. On the other hand, enabling the handle assembly 300 to rotate and separate from the body assembly 200 when the bracket 310 is in the unlocked state allows the user to hold the handle assembly 300 and apply less pushing force to push the brush assembly 100 and the body assembly 200 along the surface being cleaned, making operation convenient, effectively reducing user fatigue when using the floor scrubber, and improving the user experience.

[0055] In some embodiments of this application, see Figure 1 , Figure 3 , Figure 4 and Figure 5 The body assembly 200 includes a body 210, and the body 210 has an abutment 211 on the side near the bracket 310. The bracket 310 has a support groove 311 for accommodating the abutment 211.

[0056] Specifically, the middle part of the fuselage 210 on the side near the bracket 310 protrudes towards the bracket 310, and this protruding structure forms an abutment part 211. The bracket 310 includes a support base plate 313 and two limiting side plates 314 respectively connected to opposite sides of the support base plate 313. The two limiting side plates 314 are parallel and perpendicular to the support base plate 313. Thus, the support base plate 313 and the two limiting side plates 314 form a support groove 311 with an opening facing the abutment part 211.

[0057] When the bracket 310 is locked to the body assembly 200, the abutment part 211 on the body 210 is correspondingly accommodated in the support groove 311 on the bracket 310.

[0058] Thus, when the bracket 310 drives the body assembly 200 to rotate synchronously relative to the floor brush assembly 100 to an inclined state relative to the surface being cleaned or to a flat state parallel to the surface being cleaned, the bracket 310 can support and limit the entire body assembly 200, reducing the probability of the body assembly 200 shifting or wobbling relative to the floor brush assembly 100, improving the stability of the floor scrubber in the corresponding environment, and thus improving the cleaning effect.

[0059] Further, see Figure 1 , Figure 4 , Figure 5 and Figure 6 The body 210 is also provided with a limiting part 212 on the side near the bracket 310. The bracket 310 is provided with a plug-in part 312, which can be interference-fitted with the limiting part 212 to make the bracket 310 locked.

[0060] Specifically, the limiting part 212 is constructed as a limiting groove. Along the direction from the bottom to the top of the limiting groove, the inner diameter of the limiting groove gradually decreases. The shape of the limiting groove is not limited and can be, but is not limited to, a straight groove, a cross groove, etc. The limiting part 212 can be constructed as a plastic part so that it can be easily deformed under the action of large external pressure and has the ability to recover its deformation.

[0061] Correspondingly, the insertion part 312 is constructed as a cylindrical member mounted on the bracket 310. For example, when the limiting part 212 is an arc-shaped groove, the insertion part 312 corresponds to a cylindrical rod; when the limiting part 212 is a square groove, the insertion part 312 corresponds to a square rod. With this configuration, when the cylindrical member is inserted into the limiting groove with a gradually decreasing inner diameter using external force, it can engage with the limiting groove to form an interference fit, thereby locking the bracket 310. When the cylindrical member is pulled out of the limiting groove using external force, the bracket 310 is unlocked.

[0062] It is easy to understand that by cooperating with the limiting part 212 on the body 210 and the insertion part 312 on the bracket 310, and by forming an interference fit between the limiting part 212 and the insertion part 312, the user can manually push the bracket 310 to one side of the body 210 to form an interference fit between the insertion part 312 on the bracket 310 and the limiting part 212 on the body 210, thus locking the bracket 310 in the locked state on the body assembly 200. The user can also manually pull the bracket 310 out from one side of the body 210 to separate the insertion part 312 on the bracket 310 from the limiting part 212 on the body 210, thus unlocking the bracket 310. This allows the user to easily switch between the locked and unlocked states of the bracket 310 through simple manual operation, providing convenience for the user to hold the handle 320 and operate the floor scrubber for cleaning operations.

[0063] Of course, in other embodiments, the bracket 310 can be locked to the body 210 by means of a snap-fit, magnetic electronic lock or other structure. Compared with the interference fit between the body 210 and the bracket 310, the structure is more complex and the cost is higher.

[0064] In some embodiments of this application, see Figure 3 , Figure 7 and Figure 8 The handle assembly 300 also includes a rotating member 330, and the bracket 310 is rotatably connected to the floor brush assembly 100 via the rotating member 330. The rotating member 330 is also coaxially connected to the body assembly 200.

[0065] Specifically, the bottom end of the bracket 310 is fastened to the rotating part 330 by a pin. The rotating part 330 is rotatably connected to the housing 120 of the floor brush assembly 100 by a first rotating shaft (not shown in the figure). The body 210 of the body assembly 200 is also rotatably connected to the housing 120 of the floor brush assembly 100 by the aforementioned first rotating shaft, so that the rotating part 330 and the body assembly 200 are coaxially connected.

[0066] This design allows the handle assembly 300 to rotate independently around the connection point with the brush assembly 100 relative to the body assembly 200 when the bracket 310 is in the unlocked state, enabling it to rotate relative to the body assembly 200. This facilitates the user's grip on the handle assembly 300 and the application of a small pushing force to push the brush assembly 100 and the body assembly 200 along the surface being cleaned, while ensuring that the movement of the handle assembly 300 does not interfere with the body assembly 200.

[0067] On the other hand, when the bracket 310 is locked in the locked state of the body assembly 200, the body assembly 200 can rotate synchronously with the handle assembly 300 relative to the brush assembly 100 under the coaxial constraint of the rotating member 330, maintaining the synchronicity of the movement of the body assembly 200 and the handle assembly 300, so that the handle assembly 300 and the body assembly 200 can switch between upright, tilted and flat states at the same time, meeting the user's cleaning needs for various cleaning environments.

[0068] Furthermore, the fuselage assembly 200 has a pipe interface 220, and the rotating component 330 has an arc-shaped groove 331 that mates with the arc surface of the pipe interface 220.

[0069] It should be noted that the body assembly 200 includes a body 210 and a wastewater tank (not shown in the figure) disposed inside the body 210. The floor brush assembly 100 includes a housing 120, a roller brush 130 disposed on the housing 120, and a suction structure 150 disposed inside the housing 120.

[0070] The bottom of the fuselage 210 forms a pipe interface 220 that extends into the housing 120. The pipe interface 220 is connected to the sewage tank inside the fuselage 210. The pipe interface 220 is constructed as an L-shaped circular pipe structure, that is, the pipe interface 220 includes a vertical section and a horizontal section that are connected to each other.

[0071] The suction structure 150 can be a combination structure of suction pipe and suction fan installed inside suction pipe. The suction pipe is connected to the horizontal section of pipe interface 220 through corrugated pipe 160. The arc-shaped outer wall of corrugated pipe 160 and the arc surface of the horizontal section of pipe interface 220 are matched with the arc-shaped groove 331 on rotating component 330.

[0072] With this configuration, when the user rotates the handle assembly 300 to a state separate from the body assembly 200 based on actual usage needs, the rotating component 330 rotates around the connection point with the floor brush assembly 100, and also around the arc surface that mates with the outer wall of the pipe interface 220. This ensures that the rotating component 330 will not cause structural interference with the body assembly 200 during rotation, nor will it pull on the corrugated pipe 160 and affect the suction function of the suction structure 150. This allows the handle assembly 300 to smoothly rotate and detach from the body assembly 200 under the drive of the rotating component 330.

[0073] Furthermore, when the user rotates the handle assembly 300 and the body assembly 200 synchronously to a tilted or flat position based on actual usage needs, the bracket 310 is locked to the body assembly 200 at this time. Under the constraint of the locked state of the bracket 310, the rotating part 330 will not rotate relative to the arc surface of the pipe interface 220. Instead, the two remain relatively stationary and rotate synchronously around the connection between the rotating part 330 and the floor brush assembly 100. This also ensures that the rotating part 330 will not form structural interference with the body assembly 200 during rotation. Due to its own deformation properties, the corrugated pipe 160 stretches or contracts during the rotation of the body assembly 200, causing the handle assembly 300 and the body assembly 200 to rotate synchronously relative to the floor brush assembly 100 to a tilted or flat position.

[0074] Furthermore, during the process of the handle assembly 300 and the body assembly 200 rotating synchronously relative to the brush assembly 100 to a tilted or flat state, the arc groove 331 on the rotating part 330 also serves to stop and limit the body assembly 200, reducing the relative looseness or wobbling between the body assembly 200 and the bracket 310, and improving the motion stability of the handle assembly 300 and the body assembly 200 rotating synchronously relative to the brush assembly 100 to a tilted or flat state.

[0075] See also some embodiments of this application. Figure 1 The body assembly 200 has a fixed state locked to the floor brush assembly 100 and an active state that can move relative to the floor brush assembly 100; when the bracket 310 is in the unlocked state and the body assembly 200 is in the fixed state, the bracket 310 can rotate relative to the body assembly 200 and / or the floor brush assembly 100; when the bracket 310 is in the locked state and the body assembly 200 is in the active state, the bracket 310 can drive the body assembly 200 to rotate relative to the floor brush assembly 100.

[0076] Specifically, the body assembly 200 includes a body 210 and a wastewater tank disposed on the body 210, and the floor brush assembly 100 includes a housing 120 and a roller brush 130 disposed on the housing 120. The housing 120 has a locking groove (not shown in the figure), and the body 210 has a locking key (not shown in the figure) that mates with the locking groove. The locking key and the locking groove can be locked together by means of snap-fit ​​engagement, elastic pressing engagement, etc. When the locking key is removed from the locking groove, the lock is released. Thus, the body assembly 200 as a whole has both a fixed state locked to the floor brush assembly 100 and a movable state that can move relative to the floor brush assembly 100.

[0077] Of course, in other embodiments, the housing 120 and the body 210 can also be locked together by a magnetic electronic lock structure.

[0078] It should be understood that when the bracket 310 is in the unlocked state and the body assembly 200 is in the fixed state, when the handle assembly 300 rotates and separates from the body assembly 200 under the drive of the bracket 310, the body assembly 200 is constrained and fixed by the floor brush assembly 100 and will not rotate with the handle assembly 300. It will also not shake or tip over during the rotation of the handle assembly 300 or during the movement of the detergent along the surface being cleaned. This ensures the overall stability of the body assembly 200, and thus allows the floor scrubber to continue cleaning stably when the user manually operates the handle assembly 300 to change its position or pushes the floor scrubber.

[0079] When the bracket 310 is locked and the body assembly 200 is active, the user can hold the operating handle 320 to rotate the handle assembly 300 and the body assembly 200 synchronously relative to the floor brush assembly 100. This allows the handle assembly 300 and the body assembly 200 to switch between upright, tilted, and flat positions simultaneously. By pushing the handle 320, the user can keep the handle assembly 300 and the body assembly 200 in an upright, tilted, or flat position, and move them under the influence of the floor brush assembly 100, thus meeting the user's cleaning needs for various cleaning environments.

[0080] Further, see Figure 7 The body assembly 200 has a metal part 230, and the floor brush assembly 100 is provided with a magnetic part 110 that corresponds to and cooperates with the metal part 230.

[0081] Specifically, the metal part 230 is constructed as an iron block, and the magnetic part 110 is constructed as a magnet capable of magnetically attracting the iron block. The metal part 230 can be directly set on the body 210 of the body assembly 200, and the magnetic part 110 is correspondingly set on the housing 120 of the floor brush assembly 100.

[0082] It should be understood that when the body assembly 200 is locked in the fixed state of the floor brush assembly 100, the magnetic attachment 110 on the floor brush assembly 100 magnetically attracts the metal part 230 on the body assembly 200, so that the weight of the body assembly 200 is completely borne by the floor brush assembly 100. In this way, the downward pressure applied by the roller brush 130 of the floor brush assembly 100 to the surface being cleaned is increased, so that the roller brush 130 can more powerfully scrub the stubborn stains on the surface being cleaned, thereby improving the cleaning effect on the surface being cleaned.

[0083] Meanwhile, after the handle assembly 300 is rotated and separated from the body assembly 200 to an inclined state, the handle assembly 300 is basically not subjected to pressure from the body assembly 200 because the body assembly 200 is tightly attracted by the floor brush assembly 100. Thus, when the user holds the handle assembly 300 and applies a smaller pushing force, he can push the floor brush assembly 100 and the body assembly 200 along the surface being cleaned, making operation convenient and effectively reducing the user's fatigue when using the floor scrubber, thus improving the user experience.

[0084] In some embodiments of this application, the top of the floor brush assembly 100 is higher than or equal to the top of the body assembly 200.

[0085] This design ensures that the body assembly 200 does not protrude relative to the floor brush assembly 100 in the vertical direction, making it easier for the user to operate the handle assembly 300 to push the floor brush assembly 100 into low-lying locations such as under beds and tables for cleaning. This prevents the body assembly 200 from interfering with structures in low-lying locations due to its excessive height, thus better meeting the user's cleaning needs in various cleaning environments and further improving the user experience.

[0086] See also some embodiments of this application. Figure 1 , Figure 2 , Figure 3 and Figure 7 The floor brush assembly 100 includes a housing 120, a roller brush 130, and a booster wheel 140. The roller brush 130 is rotatably disposed on the housing 120 and partially protrudes from the housing 120. The booster wheel 140 is rotatably disposed on the housing 120 and partially protrudes from the housing 120, so as to drive the floor brush assembly 100 to move along the surface to be cleaned.

[0087] Specifically, the roller brush 130 has bristles for brushing the surface to be cleaned, and a first motor (not shown in the figure) is also provided inside the housing 120. The drive end of the first motor is connected to the roller brush 130 to drive the roller brush 130 to rotate around its own axis to perform a rotational brushing operation.

[0088] The assist wheel 140 is constructed of rubber to increase friction with the surface being cleaned. A portion of the assist wheel 140 extends from the bottom of the housing 120 to contact the surface being cleaned, providing overall support for the floor scrubber. A second motor (not shown in the figure) is also installed inside the housing 120. The drive end of the second motor is connected to the assist wheel 140, driving it to rotate around its own axis, thus moving the entire floor scrubber along the surface being cleaned for cleaning operations.

[0089] It is easy to understand that users can manually push the floor scrubber by holding the push handle 320, or they can use the assist wheel 140 to assist, reducing the force required for manual pushing, further reducing user fatigue when using the floor scrubber, and improving the user experience.

[0090] See also some embodiments of this application. Figure 4 and Figure 5 The handle 320 and the bracket 310 are detachably connected.

[0091] Specifically, the handle 320 can be detached and connected to the bracket 310 via interference fit, threaded connection, or other detachable means, so that the handle 320 can be disassembled and replaced.

[0092] Of course, in other embodiments, the handle 320 has a locked state where it is locked to the bracket 310 and an unlocked state where it can rotate relative to the bracket 310. In this embodiment, the handle 320 can be rotatably connected to the bracket 310 and is connected to the bracket 310 through locking structures such as a buckle, a magnetic electronic lock, and a pressing engagement structure between a lock groove and a lock tongue, so that the handle 320 can rotate at any angle relative to the bracket 310 and remain fixed relative to the bracket 310.

[0093] Thus, when the handle assembly (300) is in a flat position, the user can independently rotate the handle 320 upward relative to the bracket 310 at a certain angle and then fix it. In this way, the user can stand up and push the handle 320 to make the floor scrubber perform cleaning operations at a low position, without having to squat down to operate and push the handle 320. This better meets the user's cleaning needs for various cleaning environments and further improves the user experience.

[0094] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0095] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
