[0040] A floor scrubber is a cleaning machine that is suitable for cleaning hard floors while sucking out dirty water and taking it away from the ground. It has the advantages of environmental protection, energy saving, and high efficiency.

[0041] In the related art, a floor scrubber includes a roller brush and a body. A clean water tank and a sewage tank are provided on the body. The clean water in the clean water tank is sprayed onto the surface of the roller brush, and then the roller brush is rolled along the surface to be cleaned. When the floor scrubber is in the cleaning operation, the sewage generated during the cleaning process will be sucked into the sewage tank. After long-term use, the weight of the body will increase. When the user manually pushes the floor scrubber for a long time, the user needs to overcome a large force, which consumes a lot of physical energy, is time-consuming and labor-intensive, and affects the user experience.

[0042] Based on the problems that existing floor scrubbers are laborious to use and have poor user experience, one or more embodiments of the present application provide a floor scrubber, which is configured such that a body assembly is rotatably connected to a floor brush assembly, and a bracket of a handle assembly is rotatably connected to the floor brush assembly, and the bracket has a locked state locked to the body assembly and an unlocked state capable of being separated from the body assembly. On the one hand, when the bracket is in the locked state, the handle assembly is synchronously switched with the body assembly between an upright state, an inclined state or a lying state, and moves driven by the floor brush assembly, thereby meeting the user's cleaning needs in a variety of cleaning environments. On the other hand, when the bracket is in the unlocked state, the handle assembly can be rotatably separated from the body assembly, so that the user can hold the handle assembly and apply a smaller pushing force to push the floor brush assembly and the body assembly to operate along the cleaned surface. The operation is convenient, and can effectively reduce the user's fatigue when using the floor scrubber, thereby improving the user's experience.

[0043] See also Figure 1 , Figure 2 and Figure 3 An embodiment of the present application provides a floor scrubber, 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 locked to the body assembly 200 and an unlocked state capable of being separated from the body assembly 200. The bracket 310 is rotatably connected to the floor brush assembly 100.

[0045] The bracket 310 can be rotated and separated relative to the body assembly 200 when in an unlocked state, and the bracket 310 can drive the body assembly 200 to rotate relative to the brush assembly 100 when in a locked state.

[0046] It should be noted that, in the present application, the fuselage assembly 200 may include a 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 dirt suction structure 150 disposed on the housing 120. The floor scrubber may further 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 clean water.

[0048] It should also be noted that in the handle assembly 300 of the present application, the handle 320 refers to a component for the user to manually hold and operate to push the entire floor scrubber to move along the cleaned surface to perform 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 connected to the bracket 310 in a detachable manner such as interference fit, threaded connection, etc., so that the handle 320 can be disassembled and replaced.

[0049] When the floor scrubber of the embodiment of the present application performs cleaning operations, the clean water tank sprays the clean water therein onto the surface of the roller brush 130, and the user holds the handle 320 to push the floor scrubber as a whole to move along the cleaned surface. During this process, the roller brush 130 on the floor brush assembly 100 (which can be driven to rotate around its own axis by a driving member such as a motor) synchronously rotates and rolls along the cleaned surface, and the roller brush 130 continuously scrubs the cleaned surface. At the same time, during this process, the sewage tank on the body assembly 200 will suck the sewage generated on the cleaned surface through the sewage suction structure 150 of the floor brush assembly 100, thereby achieving the effect of scrubbing and cleaning the cleaned surface.

[0050] In the present application, the body assembly 200 is rotatably connected to the floor brush assembly 100, so that the body assembly 200 as a whole can 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, so that the handle 320 can rotate relative to the floor brush assembly 100 driven by the bracket 310, that is, the handle assembly 300 as a whole can rotate relative to the floor brush assembly 100.

[0051] The bracket 310 has a locked state locked to the body assembly 200 and an unlocked state capable of being 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 arrangement, when the bracket 310 is in a locked state, 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, so that the handle assembly 300 and the body assembly 200 can be switched between an upright state, an inclined state and a lying state at the same time. By pushing the handle 320, the user can make the handle assembly 300 and the body assembly 200 synchronously maintain an upright state (perpendicular to the cleaned surface), an inclined state (tilted relative to the cleaned surface) or a lying state (parallel to the cleaned surface), and move under the drive of the floor brush assembly 100, thereby meeting the user's cleaning needs for a variety of cleaning environments.

[0053] When the bracket 310 is in the unlocked state, the bracket 310 can be detached from the body assembly 200, and the body assembly 200 cannot rotate with the handle assembly 300 and remain relatively stationary with the floor brush assembly 100. At this time, the user can hold the operating handle 320 to rotate the handle assembly 300 relative to the floor brush assembly 100, so that the handle assembly 300 is relatively separated from the body assembly 200. At this time, the user can hold the handle assembly 300 and apply a smaller pushing force to push the floor brush assembly 100 and the body assembly 200 to operate along the cleaned surface, which is convenient to operate, can effectively reduce the user's fatigue when using the floor scrubber, and improve the user's experience.

[0054] It is not difficult to understand that the floor scrubber of the embodiment of the present application is connected to the floor brush assembly 100 by rotating the body assembly 200, and the bracket 310 of the handle assembly 300 is connected to the floor brush assembly 100, and the bracket 310 has a locked state locked to the body assembly 200 and an unlocked state that can be separated from the body assembly 200. On the one hand, when the bracket 310 is in the locked state, the handle assembly 300 is synchronously switched between the upright state, the inclined state or the lying state with the body assembly 200, and moves under the drive of the floor brush assembly 100, so as to meet the user's cleaning needs for various cleaning environments; on the other hand, when the bracket 310 is in the unlocked state, the handle assembly 300 can be rotated and separated relative to the body assembly 200, so that the user can hold the handle assembly 300 and apply a smaller pushing force to push the floor brush assembly 100 and the body assembly 200 to operate along the cleaned surface. The operation is convenient, which can effectively reduce the user's fatigue when using the floor scrubber and improve the user's experience.

[0055] In some embodiments of the present application, see Figure 1 , Figure 3 , Figure 4 and Figure 5 The fuselage assembly 200 includes a fuselage 210 , a side of the fuselage 210 close to the bracket 310 is provided with a supporting portion 211 , and the bracket 310 is provided with a supporting groove 311 for accommodating the supporting portion 211 .

[0056] Specifically, the middle part of the side of the fuselage 210 close to the bracket 310 protrudes toward the bracket 310, and the protruding structure forms the abutting portion 211. The bracket 310 includes a supporting bottom plate 313 and two limiting side plates 314 respectively connected to opposite sides of the supporting bottom plate 313, and the two limiting side plates 314 are parallelly distributed and perpendicular to the supporting bottom plate 313, so that the supporting bottom plate 313 and the two limiting side plates 314 surround a supporting groove 311 with an opening toward the abutting portion 211.

[0057] When the bracket 310 is in a locked state locked to the body assembly 200 , the abutting portion 211 on the body 210 is correspondingly received in the supporting groove 311 on the bracket 310 .

[0058] In this way, when the bracket 310 drives the body assembly 200 to rotate synchronously with respect to the floor brush assembly 100 to an inclined state relative to the cleaned surface or to a lying state parallel to the cleaned surface, the bracket 310 can support and limit the body assembly 200 as a whole, reduce the probability of the body assembly 200 offset and shaking relative to the floor brush assembly 100, improve the stability of the user using the floor scrubber to perform cleaning operations in the corresponding environment, and thereby improve the cleaning effect.

[0059] Further, see Figure 1 , Figure 4 , Figure 5 and Figure 6 A limiting portion 212 is further provided on one side of the body 210 close to the bracket 310 , and a plug-in portion 312 is provided on the bracket 310 , and the plug-in portion 312 can be plugged in with the limiting portion 212 in an interference fit so that the bracket 310 is in a locked state.

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

[0061] Correspondingly, the plug-in part 312 is configured as a columnar member disposed on the bracket 310. For example, when the limiting part 212 is an arc-shaped groove, the plug-in part 312 is correspondingly a cylindrical rod; when the limiting part 212 is a square groove, the plug-in part 312 is correspondingly a square rod. In this configuration, when the columnar member is inserted into the limiting groove with a gradually decreasing inner diameter with the help of an external force, it can be plugged and matched with the limiting groove to form an interference plug-in fit, thereby placing the bracket 310 in a locked state. When the columnar member is pulled out of the limiting groove with the help of an external force, the bracket 310 is in an unlocked state.

[0062] It is not difficult to understand that, by the matching setting of the limiting portion 212 on the fuselage 210 and the plug-in portion 312 on the bracket 310, and making the limiting portion 212 able to form an interference fit with the plug-in portion 312, the user can manually push the bracket 310 to one side of the fuselage 210 to form an interference fit with the plug-in portion 312 on the bracket 310, so that the bracket 310 is in a locked state locked in the fuselage assembly 200. The user can manually pull the bracket 310 out from one side of the fuselage 210 to separate the plug-in portion 312 of the bracket 310 from the limiting portion 212 on the fuselage 210, so that the bracket 310 is in an unlocked state, which is convenient for the user to switch the locked state and the unlocked state of the bracket 310 through simple manual operation, and provides convenience for the user to hold the handle 320 to operate the entire floor scrubber to perform cleaning operations.

[0063] Of course, in other embodiments, the bracket 310 can be locked with the body 210 through structures such as snaps, magnetic electronic locks, etc. Compared with the interference fit between the body 210 and the bracket 310, the structure is more complicated and the cost is higher.

[0064] In some embodiments of the present application, see Figure 3 , Figure 7 and Figure 8 The handle assembly 300 further includes a rotating member 330 , through which the bracket 310 is rotatably connected to the floor brush assembly 100 , and 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 member 330 via a latch, and the rotating member 330 is rotatably connected to the housing 120 of the floor brush assembly 100 via 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 via the above-mentioned first rotating shaft, so that the rotating member 330 and the body assembly 200 are coaxially connected.

[0066] With such arrangement, on the one hand, when the bracket 310 is in an unlocked state in which it can be rotated and disengaged relative to the body assembly 200, the handle assembly 300 as a whole can be rotated independently around the connection with the floor brush assembly 100 relative to the body assembly 200 under the drive of the rotating member 330, so that the user can hold the handle assembly 300 and apply a small pushing force to push the floor brush assembly 100 and the body assembly 200 to operate along the cleaned surface, and the movement of the handle assembly 300 will not interfere with the body assembly 200.

[0067] On the other hand, when the bracket 310 is in a locked state with 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, thereby maintaining the synchronization of the movement of the body assembly 200 and the handle assembly 300, and allowing the handle assembly 300 and the body assembly 200 to switch between an upright state, an inclined state, and a lying state at the same time, thereby meeting the user's cleaning needs for a variety of cleaning environments.

[0068] Furthermore, the fuselage assembly 200 has a pipe interface 220 , and the rotating member 330 is formed with an arc groove 331 that matches the arc surface of the pipe interface 220 .

[0069] It should be noted that the body assembly 200 includes a body 210 and a sewage tank (not shown) 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 sewage suction structure 150 disposed inside the housing 120 .

[0070] A pipe interface 220 extending into the interior of the shell 120 is formed at the bottom of the fuselage 210. The pipe interface 220 is connected to the sewage tank in the fuselage 210. The pipe interface 220 is constructed as an L-shaped circular tube structure, that is, the pipe interface 220 includes a vertical section and a horizontal section that are connected to each other.

[0071] The sewage suction structure 150 can be a matching structure of a sewage suction pipe and a suction fan arranged inside the sewage suction pipe. The sewage suction pipe is connected to the horizontal section of the pipe interface 220 through the bellows 160. The arc-shaped outer wall of the bellows 160 and the arc-shaped surface of the horizontal section of the pipe interface 220 correspond to the arc-shaped groove 331 on the rotating part 330.

[0072] In this way, when the user rotates the handle assembly 300 to a state separated from the body assembly 200 based on actual usage needs, the rotating member 330 rotates around the connection with the floor brush assembly 100, and also rotates around the arc surface that cooperates with the outer wall of the pipe interface 220, so that the rotating member 330 will not form structural interference with the body assembly 200 during the rotation process, nor will it pull the bellows 160 to affect the dirt suction function of the dirt suction structure 150, so that the handle assembly 300 can be smoothly rotated and separated from the body assembly 200 under the drive of the rotating member 330.

[0073] In addition, when the user rotates the handle assembly 300 and the body assembly 200 as a whole to an inclined state or a lying state synchronously based on actual usage needs, since the bracket 310 is in a locked state locked to the body assembly 200 at this time, the rotating member 330 will not rotate relative to the arc surface of the pipe interface 220 under the constraint of the locked state of the bracket 310, but the two will remain relatively still and rotate synchronously around the connection between the rotating member 330 and the floor brush assembly 100. Similarly, the rotating member 330 will not form structural interference with the body assembly 200 during the rotation process. The bellows 160 is elongated or contracted during the rotation of the body assembly 200 due to its own deformation properties, so that the handle assembly 300 and the body assembly 200 are synchronously rotated relative to the floor brush assembly 100 to an inclined state or a lying state.

[0074] Moreover, during the process of the handle assembly 300 and the body assembly 200 being synchronously rotated relative to the brush assembly 100 to an inclined state or a lying state, the arc groove 331 on the rotating member 330 also serves as a stop and limit for the body assembly 200, thereby reducing the relative looseness or shaking between the body assembly 200 and the bracket 310, and improving the movement stability of the handle assembly 300 and the body assembly 200 being synchronously rotated relative to the brush assembly 100 to an inclined state or a lying state.

[0075] In some embodiments of the present application, see Figure 1 The body assembly 200 has a fixed state locked to the floor brush assembly 100 and an active state capable of moving relative to the floor brush assembly 100; when the bracket 310 is in an unlocked state and the body assembly 200 is in a 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 a locked state and the body assembly 200 is in an 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 sewage tank disposed on the body 210, and the floor brush assembly 100 includes a shell 120 and a roller brush 130 disposed on the shell 120. The shell 120 is provided with a lock slot (not shown in the figure), and the body 210 is provided with a lock key (not shown in the figure) that matches the lock slot. The lock key and the lock slot can be locked by snap-fitting, elastic pressing, etc. When the lock key is removed from the lock slot, the lock is released. In this way, the body assembly 200 as a whole 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.

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

[0078] It should be understood that when the bracket 310 is in an unlocked state and the body assembly 200 is in a fixed state, when the handle assembly 300 is rotated and separated relative to the body assembly 200 as a whole 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, nor will it shake or tip over during the rotation of the handle assembly 300 and the movement of the detergent along the cleaned surface. This ensures the overall position stability of the body assembly 200, and enables the floor scrubber to perform cleaning operations stably when the user manually operates the handle assembly 300 to switch the position state of the handle assembly 300 and pushes the floor scrubber.

[0079] When the bracket 310 is in a locked state and the body assembly 200 is in an active state, the user can hold the operating handle 320 to rotate the handle assembly 300 and the body assembly 200 relative to the floor brush assembly 100 synchronously, so that the handle assembly 300 and the body assembly 200 can switch between an upright state, an inclined state and a lying state at the same time. By pushing the handle 320, the handle assembly 300 and the body assembly 200 can be synchronously maintained in an upright state, an inclined state or a lying state, and moved driven by the floor brush assembly 100, thereby meeting the user's cleaning needs for various cleaning environments.

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

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

[0082] It should be understood that when the body assembly 200 is in a fixed state locked to the floor brush assembly 100, the magnetic attraction part 110 on the floor brush assembly 100 magnetically attracts the metal part 230 on the body assembly 200, so that the gravity 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 on the cleaned surface is increased, so that the roller brush 130 can more forcefully scrub stubborn stains on the cleaned surface, thereby improving the cleaning effect on the cleaned surface.

[0083] At the same time, after the handle assembly 300 is rotated and separated relative to the body assembly 200 to an inclined state, since the body assembly 200 is tightly adsorbed by the floor brush assembly 100, the handle assembly 300 is basically not subjected to the pressure of the body assembly 200. In this way, the user can hold the handle assembly 300 and apply a smaller pushing force to push the floor brush assembly 100 and the body assembly 200 to operate along the cleaned surface. The operation is convenient, which can effectively reduce the user's fatigue when using the floor scrubber and enhance the user's experience.

[0084] In some embodiments of the present application, the top of the floor brush assembly 100 is higher than the top of the body assembly 200 or is at the same height as the top of the body assembly 200 .

[0085] Such arrangement ensures that the body assembly 200 as a whole does not protrude relative to the floor brush assembly 100 in the vertical height direction, making it convenient for the user to operate the handle assembly 300 to push the floor brush assembly 100 to enter low locations such as under the bed and under the table for cleaning operations, thereby preventing the body assembly 200 from interfering with structures in low locations due to its excessive height, thereby better meeting the user's cleaning needs in a variety of cleaning environments and further improving the user experience.

[0086] In some embodiments of the present application, see Figure 1 , Figure 2 , Figure 3 and Figure 7 The floor brush assembly 100 includes a shell 120, a roller brush 130 and a power-assisting wheel 140. The roller brush 130 is rotatably disposed on the shell 120 and partially protrudes from the shell 120. The power-assisting wheel 140 is rotatably disposed on the shell 120 and partially protrudes from the shell 120 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 cleaned surface, and a first motor (not shown in the figure) is also provided in the shell 120. The driving 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 rotary brushing operation.

[0088] The booster wheel 140 is constructed as a rubber wheel to increase the friction with the surface to be cleaned. Part of the booster wheel 140 extends out of the bottom of the housing 120 to contact the surface to be cleaned, thereby supporting the entire floor scrubber. A second motor (not shown in the figure) is also provided in the housing 120, and the driving end of the second motor is connected to the booster wheel 140 to drive the booster wheel 140 to rotate around its own axis, thereby driving the entire floor scrubber to move along the surface to be cleaned for cleaning operations.

[0089] It is not difficult to understand that the user can manually push the floor scrubber by holding the pushing handle 320, or can use the power-assisting wheel 140 to assist, thereby reducing the force of the user's manual pushing, further reducing the user's fatigue when using the floor scrubber, and improving the user's experience.

[0090] In some embodiments of the present application, see Figure 4 and Figure 5 The handle 320 is detachably connected to the bracket 310.

[0091] Specifically, the handle 320 can be matched with the bracket 310 in a detachable manner such as interference fit, threaded connection, etc., so as to facilitate the disassembly, assembly and replacement of the handle 320.

[0092] Of course, in other embodiments, the handle 320 has a locked state locked to the bracket 310 and an unlocked state capable of rotating 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 a locking structure such as a buckle, a magnetic electronic lock, a press-fit structure of a lock slot and a lock tongue, so that the handle 320 can rotate to any angle relative to the bracket 310 and remain fixed relative to the bracket 310.

[0093] In this way, when the handle assembly (300) is in a lying position as a whole, the user can independently rotate the handle 320 upward at a certain angle relative to the bracket 310 and then fix it. In this way, the user can directly stand and operate and push the handle 320, so that the floor scrubber can perform cleaning operations in a low position without squatting to operate and push the handle 320, thereby better meeting the user's cleaning needs in various cleaning environments and further improving the user experience.

[0094] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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 above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
