Description

[0001] This application is a divisional application of Chinese Patent Application No. 202310475474.0 entitled "A Floor Scrubber", the contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of cleaning equipment technology, and more particularly to a floor scrubber. Background Technology

[0003] A floor scrubber is a cleaning machine suitable for cleaning hard floors while simultaneously sucking up and removing wastewater from the site. It has advantages such as being environmentally friendly, energy-saving, and highly efficient. It includes a roller assembly for cleaning up debris on the floor and a cleaning brush assembly for sweeping up the debris adhering to the roller assembly.

[0004] In existing floor scrubber products, the water tank is usually located on the handle (the part of the floor scrubber other than the cleaning head is usually referred to as the handle). This means that when the user pushes or pulls the floor scrubber by hand, they bear the weight of the entire water tank on the handle, which can easily cause arm pain over time.

[0005] In existing floor scrubber products, the roller assembly and the cleaning brush assembly are driven by different motors. When the floor scrubber is working, the roller and brush assemblies work synchronously. The dual motors will generate a lot of noise when working at high speeds. At the same time, the dual motors also reduce the standby time of the floor scrubber.

[0006] In the aforementioned prior art, such as the floor scrubbers disclosed in Chinese patents CN111150337A, CN113876245A, and CN114680747A, the water tank is located on the handle, which can be tiring for users when pushing or pulling the scrubber by hand. For example, the floor scrubber disclosed in Chinese patent CN218009602U uses a separate drive motor to drive a gear set to rotate, thereby rotating the brush roller. The cleaning roller is driven by another separate drive motor, and the brush roller and cleaning roller rotate in opposite directions. This is more effective at brushing off sticky debris from the cleaning roller, but the separate motor driving the brush roller consumes more electricity, reducing the floor scrubber's battery life. Another example is the cleaning machine disclosed in Chinese patent CN215605440U, which uses a drive assembly that simultaneously drives the roller and cleaning brush to operate the entire cleaning machine. However, the installation structure of the cleaning brush in this solution is too complex, making it difficult to easily remove the cleaning brush from the cleaning machine for thorough cleaning.

[0007] Therefore, solving the problem of arm pain caused by prolonged use of floor scrubbers, and how to increase the standby time of floor scrubbers while reducing noise are all technical problems that urgently need to be solved. Summary of the Invention

[0043] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0044] The following will describe the scheme of this application in detail with reference to the accompanying drawings.

[0045] As analyzed in the background section of this application, existing floor scrubbers, due to their water tank being located on the handle, cause arm pain during prolonged use, have short standby times, and are noisy. To address these technical problems, this application provides a floor scrubber. Figures 1 to 8 As shown, a floor scrubber includes: a handle; a cleaning head, including a housing 40, the housing being rotatably connected to the handle at all angles; an integrated water tank 50, including a clean water chamber 501 and a wastewater chamber 502, horizontally mounted on the rear half of the housing 40 with a single-sided inlet and outlet, providing clean water for cleaning the cleaning head and collecting wastewater after cleaning; wherein, the cleaning head assembly further includes a motor 10 mounted on one side of the housing 40, a roller assembly 11 sleeved on the motor, and a brush assembly 30 spanning both sides of the housing 40, the motor 10 driving the roller assembly 11 to rotate, thereby driving the brush assembly 30 to rotate synchronously.

[0046] The floor scrubber provided in this embodiment of the invention includes a handle and a cleaning head assembly that is rotatably connected to the handle at all angles. The scrubber also includes an integrated water tank 50, horizontally mounted at the rear of the cleaning head assembly with one-sided entry and exit. The cleaning head assembly is equipped with a drive wheel (not shown) and an auxiliary wheel (not shown) to support the weight of the entire assembly, thus reducing the weight on the handle and making it easier for the user to push or pull the scrubber. The cleaning head assembly also includes a motor 10, a roller assembly 11, and a brush assembly 30. The motor 10 can drive the roller assembly 11 to rotate while simultaneously causing the brush assembly 30 to rotate synchronously with the roller assembly 11. This increases the standby time of the scrubber without increasing its size and also reduces noise during operation.

[0047] In this embodiment, the cleaning head assembly is provided with a housing 40, which includes a housing body 401. The housing body 401 is covered with a removable cover plate 404. The handle is rotatably connected to the cleaning head assembly through the housing 40. The cleaning head assembly also includes a motor 10 installed on one side of the housing 40, a roller assembly 11 sleeved on the motor 10, and a brush assembly 30 spanning both sides of the housing 40. The cleaning head assembly also includes a transmission assembly 20 installed on the other side of the housing 40. During the process of the motor 10 driving the roller assembly 11 to rotate inside the housing 40, the transmission assembly 20 rotates due to the rotation of the roller assembly 11. At the same time, the brush assembly 30 also achieves directional rotation due to the rotation of the transmission assembly 20. Thus, by setting a motor 10 inside the housing 40, the roller assembly 11 and the brush assembly 30 can be rotated synchronously, thereby increasing the standby time of the floor scrubber and reducing the noise of the floor scrubber in the working state.

[0048] In some embodiments, such as Figure 1 , Figure 2 , Figure 9 , Figure 10 , Figure 11 As shown, the housing 40 includes a housing body 401, a first side plate 402, and a second side plate 403. The first side plate 402 is integrally formed with the housing body 401. The motor 10 is mounted on the first side plate 402. The integrated water tank 50 can enter and exit the cleaning head laterally through an opening (not shown) on the first side plate 402. When the integrated water tank 50 is installed in place, the locking part 503 at one end is snapped and fixed to the side wall of the opening, and the abutting part (not shown) at the other end abuts against the side wall of the second side plate 403 facing the inside of the housing. The housing body 401 connects the first side plate 402 and the second side plate 403. A gap area (not shown) is provided between the first side plate 402 and the second side plate 403. The roller assembly 11 is detachably installed in the gap area. The motor 10 is mounted on the side of the first side plate 402 facing the inside of the housing 40 via a rotatable support (not shown in the figure). One end of the roller assembly 11 can be sleeved on the outer edge of the motor 10. The output end coupling (not shown in the figure) of the motor 10 drives the roller component 110 of the roller assembly 11 to rotate. The outer wall of the roller component 110 is sleeved with a roller wiping layer 111. The roller wiping layer 111 rotates with the roller component 110 and the two do not slide against each other. The roller assembly 11 is detachably installed in the gap area, which makes the maintenance of components such as the motor 10 simpler and also saves the manufacturing cost of the floor scrubber.

[0049] In some embodiments, such as Figure 1 , Figure 2 , Figure 9 As shown, the first side plate 402 and the second side plate 403 are respectively disposed on two opposite sides of the housing body 401 of the cleaning head assembly. That is, the housing body 401 of the cleaning head assembly is disposed in a gap area formed between the first side plate 402 and the second side plate 403. The first side plate 402 and the second side plate 403 are detachably and fixedly connected to the housing body 401. The roller assembly is respectively engaged with the first side plate 402 and the second side plate 403 in the gap area, thereby making it easier to assemble and disassemble the roller assembly 11.

[0050] In some embodiments, such as Figure 9 As shown, the second side plate 403 includes an inner layer 4031 integrally formed with the housing body 401, and an outer layer 4032 detachably connected to the housing body 401.

[0051] In some embodiments, such as Figure 9 As shown, the cleaning head assembly also includes a transmission assembly 20 disposed in the inner layer 4031 of the second side plate, and the outer layer 4032 of the second side plate is sealed over the transmission assembly 20. The roller assembly 11 and the brush assembly 30 are synchronized by the transmission assembly 20.

[0052] In some embodiments, such as Figure 3 , Figure 4 , Figures 7 to 11 As shown, the roller assembly 11 includes a roller component 110 and a first gear component 12, and the transmission assembly 20 includes a first gear component 12 and a second gear component 201. The first gear component 12 is fixedly connected to the roller component 110 and is driveably connected to the second gear component 201. The second gear component 201 is driveably connected to the brush assembly 30. In this embodiment, during the rotation of the roller component 110, the first gear component 12 and the second gear component 201 also rotate in a specific direction along with the roller component. When the second gear component 201 rotates in a specific direction, the brush assembly 30 also rotates in a specific direction along with the second gear component 201. The first gear component 12 can be detachably and fixedly connected to the roller component 110 to facilitate the assembly and disassembly of the roller component 110.

[0053] In some embodiments, such as Figures 7 to 9 As shown, the transmission assembly 20 further includes a third gear component 302, and the brush assembly 30 includes a brush body 301 and a third gear component 302; the brush body 301 and the third gear component 302 are detachably and fixedly connected, and the third gear component 302 is drively connected to the second gear component 201. Specifically, the brush body 301 includes a brush 3011 and a rotating shaft 3012, the third gear component 302 is fixed to one end face of the rotating shaft 3012 and can be detachably and fixedly connected to the rotating shaft 3012, and the brush 3011 is disposed on the circumferential surface of the rotating shaft 3012.

[0054] In some embodiments, such as Figure 9 As shown, the transmission assembly 20 may further include a transmission assembly cover 202, which seals over the transmission assembly 20. In this case, the outer layer 4032 of the second side plate no longer needs to seal over the transmission assembly 20; it only needs to be easily and detachably connected to the housing body. This allows for the application and filling of lubricating grease only in the area sealed by the transmission assembly cover 202 to the first gear 12, the second gear 201, and the third gear 302, without worrying about the lubricating grease being splashed to other places due to the second side plate outer layer 4032 not sealing the area of ​​the transmission assembly 20, or gear wear caused by lubricating grease loss due to inadequate sealing.

[0055] In this embodiment, the second gear component 201 can be a transmission gear, and the third gear component 302 can be a driven gear. That is, the second gear component 201 and the third gear component 302 mesh together. During the process of the second gear component 201 rotating in a direction with the first gear component 12, the third gear component 302 and the rotating shaft 3012 on the brush body 301 can also rotate in a direction synchronously, so that the brush assembly 30 cleans the roller wiping layer 111 of the roller assembly 11.

[0056] In some embodiments, such as Figure 10 , Figure 11 As shown, the first gear component 12 includes a gear 121 and an elastic element 122; the gear 121 is engaged with the elastic element 122, and the elastic element 122 is detachably and fixedly connected to the roller component 110 within the inner cavity of the roller component 110. In this embodiment, the gear 121 in the first gear component 12 also meshes with the second gear component 201. The elastic element 122 can serve as the rotating shaft of the roller component 110. The gear 121 of the first gear component 12 can rotate in a specific direction as the roller component 110 rotates. Simultaneously, the elastic element 122 can be detachably and fixedly connected to the roller component 110 within the inner cavity of the roller component 110, facilitating the assembly and disassembly of the roller component 110.

[0057] In some embodiments, such as Figure 10 , Figure 11 As shown, the elastic element 122 includes a rotating shaft 1221 and a spring 1222; a first abutment 12211 is provided on the outer side of the rotating shaft 1221, and the spring 1222 is sleeved on the rotating shaft 1221 and located on the side of the first abutment 12211 away from the gear 121. The rotating shaft 1221 is elastically abutted against the bushing 112 by the spring 1222, and the bushing 112 is detachably abutted against the roller 110 in the inner cavity of the roller 110. In this embodiment, the rotating shaft 1221 can serve as the rotating shaft of the roller assembly 110, and can extend and retract within the inner cavity of the roller assembly 110 via the spring 1222. When the roller assembly 11 needs to be installed in the cleaning head assembly, the spring 1222 is sleeved on the rotating shaft 1221 located on the side of the first stop 1221 away from the gear 121. By applying pressure to the end face of the rotating shaft 1221 near the gear 121, the spring 1222 is compressed by the first stop 12211, and the rotating shaft 1221 moves a certain distance. At the same time, the rotating shaft 1221 is rotated by a certain angle, so that the rotating shaft 1221 abuts against the roller assembly within the inner cavity of the roller assembly 110.

[0058] In some embodiments, such as Figure 10 , Figure 11As shown, to facilitate the assembly and disassembly of the elastic element 122 and the roller element 110, and to prevent the rotating shaft 1221 from dislodging from the roller element 110, a button 1223 is provided on the rotating shaft 1221. The button 1223 is sleeved on the side of the first abutting element 12211 near the gear 121 and abuts against the roller element 110 in the inner cavity of the roller element 110. Specifically, the button 1223 and the rotating shaft 1221 can be fixed together by screws 1226. A through hole (not shown in the figure) can be provided at both ends of the button 1223, and the screw 1226 is fixedly connected to the rotating shaft 1221 through the through hole.

[0059] In some embodiments, such as Figure 10 , Figure 11 As shown, the end of the button 1223 away from the gear 121 is provided with a second abutment 12231. A first copper sleeve 1225 is provided between the gear 121 and the second abutment 12231. A second copper sleeve 1227 is provided on the side of the gear 121 away from the button 1223. The gear 121 is fixed to the button 1223 by the first copper sleeve 1225 and the second copper sleeve 1227. Specifically, the end of the second abutment 12231 near the roller 110 can directly abut against the roller 110 in the inner cavity of the roller 110, and the end of the second abutment 12231 away from the roller 110 can be used to limit the gear 121.

[0060] It is understood that the second abutment 12231 can be an annular protrusion (not shown in the figure) formed around the circumference of the button 1223. That is to say, the second abutment 12231 and the button 1223 can be integrally formed. At the same time, the annular protrusion can be formed by multiple protrusions. The structure of the second abutment 12231 can be selected according to the actual application. This embodiment does not make specific limitations.

[0061] In some embodiments, such as Figure 10 , Figure 11 As shown, a detachable cover 1224 is fitted onto one end of the rotating shaft 1221 near the gear 121, and abuts against the roller component 110 within the inner cavity of the roller component 110. Specifically, by fitting a detachable and fixed cover 1224 onto one end of the rotating shaft 1221 near the gear 121, the cover 1224 has multiple through holes (not shown in the figure) around its end face. Screws (not shown in the figure) can be used to fix the cover 1224 onto the aforementioned bushing 112 through the through holes. A spring 1222 is fitted onto the other end of the rotating shaft 1221. One end of the spring 1222 abuts against the bushing 112, and the other end of the spring 1222 abuts against the rotating shaft 1221, thereby achieving retractable elastic abutment of the entire elastic element 122 against the bushing 112.

[0062] In some embodiments, the shaft cover 1224 is further provided with a third abutment 12241, the first abutment 12211 is located between the rotating shaft 1221 and the third abutment 12241, the shaft cover 1224 is sleeved on the first abutment 12211 and is located on the side of the third abutment 12241 near the gear 121.

[0063] In one embodiment, the third stop 12241 is used to limit the shaft cover 1224, and the first stop 12211, the third stop 12241 and the rotating shaft 1221 can be integrally formed.

[0064] It is understood that the first stop 12211 and the third stop 12241 can both be an annular protrusion formed around the circumference of the button 1223. That is to say, the first stop 12211, the third stop 12241 and the rotating shaft 1221 can be integrally formed. At the same time, the annular protrusion can be formed by multiple protrusions. The structure of the first stop 12211 and the third stop 12241 can be selected according to the actual application. This embodiment does not make specific limitations.

[0065] In some embodiments, the rotating shaft 1221 can be an integral three-section structure design, with the middle section of the rotating shaft 1221 being thicker and the two ends being thinner. The middle section of the rotating shaft 1221 can be cut with two surfaces, and the protruding part after the cut can serve as a first abutment. The part of the middle section of the rotating shaft 1221 that is not cut with two surfaces can form a third abutment.

[0066] In some embodiments, such as Figure 10 , Figure 11 As shown, the roller component 110 further includes a roller 112 and a bushing 113. A roller wiping layer 111 is sleeved on the outer wall of the roller component 110. The roller wiping layer 111 rotates with the roller component 110 and the two do not slide against each other. The elastic member 122 is detachably and fixedly connected to the bushing 113 in the inner cavity of the bushing 113. The bushing 113 is detachably and fixedly connected to the roller 112 in the inner cavity of the roller 112.

[0067] In some embodiments, such as Figure 5 , Figure 6As shown, a water-squeezing strip 407 is provided on the inner top of the housing body 401, directly above the axis of the roller assembly 11. The water-squeezing strip 407 is integrally formed with the housing body 401. A water-receiving strip 408 is snapped onto the inner top of the housing body 401, parallel to the water-squeezing strip 407 and close to the brush assembly 30. Both the water-squeezing strip 407 and the water-receiving strip 408 interfere with the roller wiping layer 111 of the roller assembly 11 and form a water tank structure (not shown in the figure). The squeezing strip 407 interferes with the roller wiping layer 111 and is used to squeeze out excess water from the roller wiping layer 111 to prevent the garbage from being too wet and difficult to clean, and to truly achieve dry and wet separation of garbage. The water-collecting strip 408 interferes with the roller wiping layer 111 and is used to collect the sewage squeezed out by the squeezing strip 407 and guide it to the sewage channel inlet (not shown in the figure) so that it can be sent away in time and will not flow along the arc surface of the roller wiping layer 111 to the garbage collection assembly 70 behind the roller assembly 11, further achieving dry and wet separation of garbage.

[0068] In some embodiments, such as Figure 3 , Figure 7 , Figure 9 As shown, the cleaning head assembly also includes a water pipe 80 disposed on the inner layer 4031 of the second side plate for sucking and conveying clean water to the water tank structure and for conveying wastewater from the water tank structure.

[0069] Specifically, such as Figure 3 , Figure 7 , Figure 9 As shown, the water pipe 80 includes a clean water pipe 801 disposed on the inner layer 4031 of the second side plate for drawing and transporting clean water from the clean water chamber 501 to the water tank structure, and a sewage pipe 802 for transporting sewage from the water tank structure to the sewage chamber 502.

[0070] In one embodiment, such as Figure 3 , Figure 7 , Figure 9As shown, the floor scrubber also includes a water pump (not shown), a water electrolysis device (not shown), and / or a filter device (not shown) installed in the handle. The clean water pipeline 801 includes a pipeline from the clean water chamber 501 and / or the filter device to the water electrolysis device and then to the water tank structure. Specifically, the water pump in the handle first draws clean water from the clean water chamber 501 to the water electrolysis device for electrolytic sterilization and disinfection through the clean water pumping pipeline 8011. When the filter device is installed in the handle, the wastewater drawn from the wastewater chamber 502 is sent to the filter device through the wastewater pumping pipeline 8021. After filtration, the wastewater becomes "secondary clean water". The "secondary clean water" is sent to the water electrolysis device for electrolytic sterilization and disinfection through another clean water pumping pipeline 8011a (not shown). After the clean water or "secondary clean water" is electrolyzed and sterilized in the water electrolysis device, it is then sent to the water tank structure through the clean water supply pipeline 8012.

[0071] In one embodiment, the sewage pipe 802 includes a sewage delivery pipe 8022 formed by a ring of weir trenches (not shown) on the inner layer 4031 of the second side plate, leading from the water tank structure to the inlet (not shown) of the sewage chamber 502. When a filter device is installed in the handle, the sewage pipe 802 also includes a sewage suction pipe 8021 for drawing sewage from the sewage chamber 502. The sewage drawn through the sewage suction pipe 8021 is sent to the filter device, where it is filtered and becomes "sub-clean water," which is then sent to the water electrolysis device for electrolytic sterilization. After electrolytic sterilization in the water electrolysis device, the "sub-clean water" is then sent to the water tank structure through a clean water delivery pipe 8012.

[0072] In one embodiment, a long, slotted through-hole (not shown in the figure) extending along the axis of the roller assembly is formed between the squeezing strip 407 and the receiving strip 408 at the top of the housing body 401. A pressure cap 406 is provided above the long slotted hole. The pressure cap 406 includes a cover plate 4061 and a sealing eave 4062. The cover plate 4061 is integrally formed, and a sealing ring (not shown in the figure) is fitted onto the sealing eave 4062. The pressure cap 406 mainly covers the water tank structure. After the floor scrubber has been used for a period of time, a certain amount of fine, sticky debris may have accumulated in the water tank structure. During normal use, the clean water sprayed from the water tank structure is no longer sufficient to wash away this sticky debris. At this time, the user can open the pressure cap 406 and use a small brush to scrub the water tank structure to further clean away the stubborn sticky debris.

[0073] In some embodiments, such as Figure 5 , Figure 9As shown, the removable cover 404 includes a removable brush bottom cover 405 that snaps onto the removable cover body (not shown in the figure). The brush bottom cover 405 prevents debris from splashing when the brush assembly 30 cleans the roller wiping layer 111, and also facilitates the brush assembly 30 to throw the brushed debris along the arc surface of the brush bottom cover 405 into the debris collection assembly 70. In addition, the pressure cover 406 is also covered with an extension of a removable cover plate 404, which is used to protect the pressure cover 406 and the roller assembly 11. When the user puts the floor scrubber back on the base after each cleaning, the cover structure of the extension of the removable cover plate 404 covering the surface of the roller wiping layer 111 helps to prevent the roller wiping layer 111 from drying and hardening due to moisture evaporation during long-term periods of non-use. When the user pushes the floor scrubber forward to clean the floor, the extension of the removable cover plate 404 can also prevent the soft roller wiping layer 111 from being scratched by obstacles during high-speed rotation when the cleaning head assembly hits an obstacle.

[0074] In some embodiments, such as Figure 1 , Figure 5 As shown, the integrated water tank 50 includes a clear water chamber 501 located at the upper part of the integrated water tank and a wastewater chamber 502 located at the lower part of the integrated water tank, separated by a partition plate (not shown in the attached diagram) in the middle of the water tank. The clear water chamber supplies clear water to the surface of the roller wiping layer 111 of the roller assembly 11, while the wastewater chamber collects wastewater flowing over the surface of the roller wiping layer 111 of the roller assembly 11. The water pipe 80 includes the clear water pipe 801 and the wastewater pipe 802. Both the clear water and wastewater flowing over the surface of the roller wiping layer 111 are confined within the water tank structure. One end of the water tank structure is connected to the clear water chamber 501 via the clear water pipe 801, and the other end is connected to the wastewater chamber via the wastewater pipe 802, forming a water circulation structure where clear water enters from one end and wastewater exits from the other.

[0075] In some embodiments, such as Figure 1 , Figure 5 , Figure 7 As shown, the floor scrubber also includes a waste collection assembly 70 and a scraper assembly 60; the waste collection assembly 70 is located behind the scraper assembly 60 and behind the roller assembly 11, and the scraper assembly 60 is located between the brush assembly 30 and the roller assembly 11.

[0076] On the other hand, the specific working method of the floor scrubber provided in this application is as follows: when the floor scrubber is turned on, the motor 10 starts to work, and the water circuit and other components work simultaneously. When the motor 10 rotates, it drives the roller assembly 11 to rotate, thereby driving the brush assembly 30 to rotate through the transmission assembly 20. After the water circuit is working, clean water is delivered to the surface of the roller wiping layer 111 of the roller assembly 11 through the clean water chamber 501 of the integrated water tank 50 and the clean water pipe 801, wetting the surface of the roller wiping layer 111 of the roller assembly 11. At the same time, the roller wiping layer 111 of the roller assembly 11 rolls and cleans the ground. The scraper assembly 60 is designed to follow the roller assembly 11. The garbage collection assembly... The 70 is located behind the roller assembly 11 and below the brush assembly 30. When the roller wiping layer 111 of the roller assembly 11 rolls and cleans the ground, the garbage on the ground is scooped up by the shovel assembly 60. Through the gap between the shovel assembly 60 and the roller wiping layer 111 of the roller assembly 11, and through the friction of the roller wiping layer 111 of the roller assembly 11, the garbage is carried into the garbage collection assembly 70. At the same time, the brush assembly 30 contacts the roller wiping layer 111 of the roller assembly 11, and the brush assembly 30 sweeps the garbage remaining on the roller wiping layer 111 of the roller assembly 11 and sweeps it into the garbage collection assembly 70, thus realizing the collection of garbage on the ground. In addition, when the floor scrubber is working, clean water is continuously delivered to the surface of the roller wiping layer 111 of the roller assembly 11. After cleaning the roller wiping layer 111 of the roller assembly 11, the clean water is squeezed out as sewage by the squeezing strip 407 of the housing body 401. The sewage enters the sewage pipe 802 through the water tank structure and is transported to the sewage chamber 502 of the integrated water tank 50 for collection.

[0077] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
