Description

Technical Field

[0001] This utility model belongs to the technical field of floor scrubbing equipment, and in particular relates to a floor scrubbing machine that facilitates cleaning of the roller brush. Background Technology

[0002] A floor scrubber is a cleaning device suitable for cleaning hard floors. It mainly consists of a body and a roller brush, water supply unit, drive unit, scraper, and recovery unit installed on the body. The drive unit is used to drive the roller brush to rotate, the water supply unit is used to spray water onto the roller brush, the scraper is fixedly installed and used to scrape off the wastewater on the roller brush, and the recovery unit is used to suck up the wastewater generated.

[0003] Among them, the roller brush, as the main cleaning component in contact with the ground, often gets tangled with hair, fibers, and other debris. Existing fixed scrapers can only scrape off sewage and cannot effectively clean the debris entangled on the roller brush, resulting in a decrease in the cleaning effect of the roller brush. Furthermore, the accumulated debris can even hinder the rotation of the roller brush, causing damage to the roller brush and drive unit. Therefore, it is necessary to design a floor scrubber that is easy to clean the roller brush to solve this problem. Utility Model Content

Detailed Implementation

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit this application. The connection relationships shown in the accompanying drawings are only for clear description and do not limit the connection method.

[0044] See appendix Figure 1 - Appendix Figure 9 A floor scrubber for easy cleaning of the roller brush includes a body 1 and a cleaning mechanism 2. A handle 11 is optionally mounted on the top of the body 1, and a roller brush 12 is provided at the bottom of the body 1. A water supply unit 3 and / or a recycling unit 4 are mounted on the body 1 or the handle 11. The water supply unit 3 provides water to wet the roller brush 12, and the recycling unit 4 recycles the generated wastewater. The cleaning mechanism 2 includes a drive unit 21 and a brush roller 22. The brush roller 22 is located beside the roller brush 12 and has bristle strips 220 that abut against the roller brush 12. The drive unit 21 is mounted on the body 1 and is drivenly connected to the roller brush 12 and the brush roller 22. The drive unit 21 can simultaneously drive the roller brush 12 and the brush roller 22 to rotate in opposite directions, ensuring that the bristle strips 220 can scrape off the wastewater on the roller brush 12 and clean the debris entangled on the roller brush 12.

[0045] Specifically, during use, after the roller brush 12 is placed against the ground, the drive unit 21 is activated to drive the roller brush 12 and the brush roller 22 to rotate in opposite directions simultaneously. Water is then supplied to the roller brush 12 through the water supply unit 3 so that the roller brush 12 can effectively scrub and absorb dust, hair and other debris on the ground, thereby completing the ground cleaning. During the cleaning process of the roller brush 12, the sewage or debris absorbed by the roller brush 12 will be carried to the brush roller 22, where the bristle strips 220 on the brush roller 22, which rotates in the opposite direction, will scrape off the sewage on the roller brush 12 and roll away the debris, thereby completing the cleaning of the roller brush 12. The scraped sewage and debris that fall off the brush roller 22 are collected by the recycling unit 4, while the debris that remains wrapped on the bristle strips 220 is manually cleaned after accumulating to a certain extent.

[0046] In summary, this utility model, by designing a drive unit 21 on the body 1 to drive the roller brush 12 and brush roller 22 to rotate relative to each other and make an involute motion, allows the roller brush 12 to rotate and clean the ground while the bristle strip 220 rotates in the opposite direction to effectively scrape off the sewage on the roller brush 12 and clean the debris wrapped around the roller brush 12. This ensures the cleaning effect of the roller brush 12, ensures that the roller brush 12 can be used continuously, improves cleaning efficiency, and also avoids the accumulation of debris from hindering the rotation of the roller brush 12 and causing damage to related components, thus extending the overall service life.

[0047] It should be noted that the debris wrapped around the roller brush 12 is usually long strips of debris such as hair and fiber lines, but it can also be blocky debris with strong adsorption such as paper pieces and cotton. Due to the variety of related debris, they are not listed one by one in this utility model.

[0048] On the other hand, during use, the user can control the movement direction of the machine body 1 by holding the handle 11 to clean the designated ground. Besides using the handle 1 to adjust the direction, other automatic steering structures (such as electric locomotives, not shown in the illustrations) can also be used to control the movement direction of the machine body 1. Therefore, the handle 11 can be selected. In actual operation, the manufacturer can choose to set the corresponding steering structure according to the user's needs, and this utility model does not impose any restrictions on this. In embodiments where the handle 11 is selected, the water supply unit 3 and the recovery unit 4 can be centrally installed on the handle 11 or the machine body 1, or the water supply unit 3 / recovery unit 4 can be set on the handle 11, and the recovery unit 4 / water supply unit 3 can be correspondingly set on the machine body 1. Meanwhile, conventional water supply units 3 and recovery units 4 are existing technologies and are quite common in this technical field, so they will not be described in detail in this utility model.

[0049] See appendix Figure 1 - Appendix Figure 9 Traditional roller brushes 12 are generally covered with a plush layer on their outer circumference, which has problems such as easy shedding of the bristles, difficulty in cleaning, and strong odor. Therefore, in this utility model, the outer circumference of the roller brush 12 is covered with a rubber layer 120, and the bristle strip 220 is composed of multiple hard bristles that abut against the rubber layer 120.

[0050] Specifically, the rubber material itself has low water absorption, which speeds up drying and reduces the probability of mold, odor, and bacterial growth. Simultaneously, the rubber layer 120 has a relatively smooth surface, strong wear resistance, and is easy to clean and use for extended periods. Furthermore, the rubber layer 120 is elastic and has a high coefficient of friction with the ground. When encountering uneven surfaces or surfaces with large particles, the rubber layer 120 can adapt and deform to effectively clean dirt, improving cleaning efficiency and quality. The use of hard bristles in conjunction with the rubber layer 120 ensures that wastewater is effectively scraped away while more easily removing hair and other strip-shaped debris entangled on the roller brush 12, improving the cleaning effect of the roller brush 12, keeping it clean, and facilitating continuous operation.

[0051] See appendix Figure 1 - Appendix Figure 9 The brush roller 22 is provided with a groove 223, and the bristle strip 220 is provided with a slider 2201 that is slidably connected to the groove 223 and interference fit. This design makes the bristle strip 220 and the brush roller 22 stable and detachable from each other, which facilitates the disassembly, replacement or cleaning and maintenance of the bristle strip 220. The bristle strip 220 can also be detached and connected to the brush roller 22 in other ways, which is not limited in this utility model.

[0052] See appendix Figure 1 - Appendix Figure 9The slide groove 223 has at least two sections that intersect and surround the brush roller 22. The bristle strip 220 has at least two sections, and each of the two bristle strips 220 has a slider 2201. The slider 2201 corresponds to and cooperates with the slide groove 223. This design allows the two bristle strips 220 to intersect and stably connect to the brush roller 22, and ensures that the brush roller 22 is subjected to balanced force on each side, thereby improving the rotational stability of the brush roller 22 and the cleaning effect on the roller brush 12.

[0053] See appendix Figure 1 - Appendix Figure 9 The machine body 1 has a first baffle 13 and a second baffle 14 on its left and right sides, respectively. The drive unit 21 includes a motor 211, a linkage cylinder 212 and a gear set 213. The motor 211 is fixedly installed on the first baffle 13, and the drive shaft of the motor 211 is coaxially fixed to the linkage cylinder 212. The roller brush 12 is coaxially sleeved on the motor 211 and the linkage cylinder 212, and the roller brush 12 is fixed to the linkage cylinder 212 and can rotate relative to the motor 211. The gear set 213 is installed on the second baffle 14, and the input end of the gear set 213 is drivenly connected to the linkage cylinder 212, and the output end of the gear set 213 is drivenly connected to the brush roller 22.

[0054] Specifically, during use, the motor 211 drives the linkage cylinder 212 to rotate, which in turn drives the roller brush 12 to rotate in the forward direction to clean the ground. The linkage cylinder 212 can also drive the brush roller 22 to rotate in the opposite direction through the gear set 213, so that the bristle strips 220 rotating in the opposite direction can scrape off the sewage on the roller brush 12 and roll away the debris wrapped around the roller brush 12. Therefore, the coordinated use of the motor 211, linkage cylinder 212 and gear set 213 can keep the roller brush 12 clean while it is working, so as to facilitate the continuous use of the roller brush 12 and improve work efficiency and cleaning effect.

[0055] It should be noted that the manufacturer can build a battery (not shown in the figure) into the body 1 or the handle stick 11 for power supply. This technology is quite common in the field and will not be described in detail in this embodiment.

[0056] See appendix Figure 1 - Appendix Figure 9 A first rotating rod 131 is rotatably mounted on the first baffle 13, and the first rotating rod 131 is detachably connected to the head end of the brush roller 22; a second rotating rod 142 is rotatably provided on the second baffle 14, which is connected to the input end of the gear set 213 and the output end of the gear set 213, and the second baffle 14 is detachably mounted on the machine body 1 so that the linkage cylinder 212 and the tail end of the brush roller 22 are detachably connected to the transmission end 141 and the second rotating rod 142, respectively.

[0057] Specifically, under normal circumstances, the second baffle 14 is installed on the machine body 1 to rotatably restrict the roller brush 12 and the brush roller 22 on the machine body 1 to ensure that they can operate stably. When it is necessary to replace or clean the brush roller 22, the second baffle 14 is first removed from the machine body 1, so that the transmission end 141 and the second rotating rod 142 are respectively disengaged from the linkage cylinder 212 and the tail end of the brush roller 22. Then, the brush roller 22 is moved so that its head end is disengaged from the first rotating rod 131, and the brush roller 22 can be removed.

[0058] On the other hand, since the roller brush 12 may still be damaged during actual use, the user can directly maintain the exposed roller brush 12 after removing the second baffle 14. In another embodiment, the linkage cylinder 212 and the drive shaft of the motor 211 can also be set to be detachable. In this way, after removing the second baffle 14, the user can also remove the linkage cylinder 212 and the roller brush 12 together for maintenance or direct replacement.

[0059] See appendix Figure 1 - Appendix Figure 9 The brush roller 22 has a first slot 221 and a second slot 222 at its two ends, and a third slot 2121 at the end of the linkage cylinder 212 away from the motor 211. The first rotating rod 131 and the second rotating rod 142 can be adapted to be inserted into the first slot 221 and the second slot 222, respectively, and the transmission end 141 can be adapted to be inserted into the third slot 2121. The design of the first slot 221 and the second slot 222 facilitates the disassembly and assembly of the brush roller 22 with the first rotating rod 131 and the second rotating rod 142. Similarly, the design of the third slot 2121 facilitates the disassembly and assembly of the linkage cylinder 212 and the transmission end 141. In addition, if it is necessary to disassemble the roller brush 12, a similar insertion structure can be adopted between the linkage cylinder 212 and the drive shaft of the motor 211 to achieve disassembly and assembly.

[0060] It should be noted that, in addition to the above structure, other detachable installation methods can also be used to detach and install the brush roller 22 from the first rotating rod 131 and the second rotating rod 142, as well as to detach and install the linkage cylinder 212 from the transmission end 141 and the drive shaft of the motor 211. This utility model does not impose any restrictions on this.

[0061] See appendix Figure 1 - Appendix Figure 9The gear set 213 consists of multiple gears, and the total number of gears must be odd to ensure that the roller brush 12 and the brush roller 22 can rotate relative to each other. The rotational speed of the roller brush 12 can be greater than or less than the rotational speed of the brush roller 22, and this utility model does not impose any restrictions on this. For ease of understanding, in this embodiment, the gear set 213 includes a main gear 2131, a transmission gear 2132, and a secondary gear 2133 rotatably connected to the second baffle 13. The main gear 2131 serves as the input end of the gear set 213 and is coaxially fixed to the transmission end 141. The secondary gear 2133 serves as the output end of the gear set 213 and is coaxially fixed to the second rotating rod 142. The transmission gear 2132 synchronously meshes with the main gear 2131 and the secondary gear 2133, and the transmission ratio between the main gear 2131 and the transmission gear 2132 is greater than 1, while the transmission ratio between the transmission gear 2132 and the secondary gear 2133 is less than 1, so that the rotational speed of the brush roller 22 is greater than the rotational speed of the roller brush 12.

[0062] Specifically, under the coordinated action of the main gear 2131, the transmission gear 2132, and the auxiliary gear 2133, the roller brush 12 and the brush roller 22 move in an involute motion and rotate in opposite directions, which makes it easier for the brush roller 22 to scrape off the sewage and debris wrapped around the roller brush 12, thus improving the cleaning effect of the roller brush 12. At the same time, since the rotation speed of the brush roller 22 is greater than that of the roller brush 12, the brush roller 22 can clean the roller brush 12 more thoroughly and quickly, thus improving the cleaning efficiency.

[0063] Furthermore, the cross-sectional diameter of the roller brush 12 is D1, and the cross-sectional diameter of the brush roller 22 is D2, with a ratio of D1 to D2 of 2.3:1; the transmission ratio of the main gear 2131 and the transmission gear 2132 is 3:1, and the transmission ratio of the transmission gear 2132 and the auxiliary gear 2133 is 1:2; under this design, the rotational speed of the brush roller 22 is 1.5 times that of the roller brush 12, so the brush roller 22 can clean the entire outer circumferential surface of the roller brush 12 after rotating one and a half revolutions, and the brush roller 22 can precisely re-align with the initial position of the roller brush 12 after rotating one revolution; this design allows the brush roller 22 to rotate stably and ensures that the brush roller 22 can more comprehensively and efficiently scrape away sewage and debris on the roller brush 12.

[0064] See appendix Figure 1 - Appendix Figure 9 The inner wall of the body 1 has an opening 15 that connects to the outside, and a locking position 150 is provided on the side of the opening 15; the second baffle 14 is provided with a locking part 5, which includes a fixing block 51, a button 52, a buckle 53 and an elastic element 54. The fixing block 51 is installed on the second baffle 14 and has an adjustment groove 510. One end of the button 52 is placed in the adjustment groove 510 and is rotatably connected to the fixing block 51. The other end of the button 52 is fixed to the buckle 53 located outside the adjustment groove 510. The elastic element 54 is provided in the adjustment groove 510 and abuts against the bottom wall of the adjustment groove 510 and the button 52.

[0065] Specifically, when it is necessary to install the second baffle 14 to drive the transmission end 141 and the second rotating rod 142 to connect the linkage cylinder 212 and the brush roller 22 respectively, first press the button 52 to drive the elastic element 54 to deform and store energy, then move the second baffle 14 to abut against the side wall of the machine body 1 so that the button 52 is inserted into the notch 15 and the latch is aligned with the locking position 150. At this time, release the button 52, the elastic element 54 releases energy and restores itself, and applies pressure to the button 52 to drive the buckle 53 to engage with the locking position 150 and lock the second baffle 14 onto the machine body 1. Similarly, when the button 52 is pressed again to drive the buckle 53 to disengage from the locking position 150 and move the second baffle 14 outward, the transmission end 141 and the second rotating rod 142 can be disengaged from the linkage cylinder 212 and the brush roller 22 respectively, making it convenient for the user to disassemble the brush roller 22 for maintenance.

[0066] The design of the second baffle 14 provides an installation position for the gear set 213, making it convenient for users to perform independent maintenance on the gear set 213; it also provides a point of leverage for easy movement. Furthermore, the second baffle 14 provides operational feedback when it comes into contact with the machine body 1, prompting the user to install it in place, thus improving operational convenience.

[0067] It should be noted that the elastic element 54 can be a rubber strip, a spring, etc., and the locking part 5 can also adopt other structures with the same function in addition to the above-mentioned structure. Since there are many related structures, this invention and utility model do not limit them.

[0068] See appendix Figure 1 - Appendix Figure 9 Both the water supply unit 3 and the recycling unit 4 are installed on the machine body 1. The water supply unit 3 includes a clean water tank 31 and a water conveying unit 32, and the recycling unit 4 includes a wastewater tank 41 and a scraper 42. The water conveying unit 32 is connected to the clean water tank 31 and corresponds to the roller brush 12 to transport the water in the clean water tank 31 to the roller brush 12. The wastewater tank 41 is located at the bottom of the machine body 1 and directly below the brush roller 22 to load the wastewater scraped off by the brush roller 22 and the debris cleaned up. The scraper 42 is installed on the wastewater tank 41 and abuts against the roller brush 12 to further scrape the wastewater and debris remaining on the roller brush 12 into the wastewater tank 41.

[0069] Specifically, during use, the drive unit 21 is first activated to drive the roller brush 12 to rotate. Then, the water supply unit 32 delivers clean water or cleaning solution from the clean water tank 31 to the roller brush 12, wetting it. The roller brush 12 can then effectively scrub and absorb dust, hair, and other debris on the ground to complete the floor cleaning. During the cleaning process, the wastewater and debris absorbed by the roller brush 12 will pass through the brush roller 22 and scraper 42 in sequence. The brush roller 22 first scrapes away most of the wastewater on the roller brush 12 and rolls away the strip-shaped debris wrapped around it. Then, the scraper 42 further scrapes away the wastewater and debris remaining on the roller brush 12, making the roller brush 12 more thoroughly cleaned and further improving its cleanliness. The scraped wastewater and cleaned debris fall into the wastewater tank 41 under gravity for centralized storage, completing the recycling of wastewater and debris for continued floor cleaning.

[0070] In summary, this utility model, through the combined use of the brush roller 22, scraper 42, roller brush 12, and wastewater tank 41, can achieve cleaning of the roller brush 12 and recycling of wastewater and debris. Compared with the conventional recycling unit 4, the recycling unit 4 in this embodiment can achieve the recycling function by designing the scraper 42 and wastewater tank 41 to work with the roller brush 12, without the need for an additional suction motor (not shown in the figure), effectively reducing manufacturing costs. At the same time, since the wastewater tank 41 can simultaneously correspond to the roller brush 12 and the brush roller 22, the space utilization rate is high, which is conducive to reducing the overall volume of the machine body 1.

[0071] On the other hand, in the embodiment where the handle rod 11 is installed on the body 1, by setting the wastewater tank 41 and the clean water tank 31 on the body 1, the overall center of gravity can be lowered, making it easier for users to operate and saving physical effort. At the same time, the handle rod 11 part can be avoided from being bulky, ensuring that users can smoothly adjust the angle between the handle rod 11 and the body 1, improving the flexibility of the floor brush and expanding the cleaning area to ensure the user experience. As for the connection method between the handle rod 11 and the body 1, a conventional swing connection or a ball joint hinge can be used to allow for multiple angles of movement between the two. There are various related hinge methods, and this utility model does not limit them.

[0072] See appendix Figure 1 - Appendix Figure 9The sewage tank 41 has multiple insert blocks 411 on its side, and each insert block 411 has a locking hole 4110 at its bottom. The scraper 42 has multiple insert holes 421 arranged in a straight line along its length, and each insert hole 421 has a locking block 4210 at its inner bottom. The multiple locking blocks 4210 can engage with the multiple locking holes 4110 one by one, and the multiple insert blocks 411 can be inserted into the multiple insert holes 421 one by one. This design allows the scraper 42 to be detachably connected to the sewage tank 41, making it convenient for users to replace and clean the scraper 42. In addition to this structure, the scraper 42 and the sewage tank 41 can also be installed in other detachable ways, which are not limited in this utility model.

[0073] See appendix Figure 1 - Appendix Figure 9 The bottom of the wastewater tank 41 is also equipped with multiple rotatable pulleys 412. The scraper 42 is also connected to a scraper blade 422 that extends along the length of the roller brush 12 and is offset from the roller brush 12. The pulleys 412, scraper blades 422 and roller brush 12 contact the ground simultaneously. The scraper blades 422 are designed to loosen large stains on the ground, making it easier for the stains to be rolled away by the roller brush 12, thereby further improving cleaning efficiency. The pulleys 412 are designed to reduce friction between the machine body 1 and the ground, increase the stability of the machine body 1, and further improve the user experience.

[0074] See appendix Figure 1 - Appendix Figure 9 A guide plate 43 is installed on the top of the sewage tank 41. The center of the guide plate 43 has an opening 431 connecting the sewage tank 41 and the outside. The guide plate 43 gradually recesses towards the opening 431 from the edge to form a guide area 432. The brush roller 22 is located directly above the guide area 432 so that the scraped sewage and cleaned debris can fall smoothly into the guide area 432. The scraper 42 is located at the edge of the guide plate 43 and extends along the length of the roller brush 12. The scraper 42 also abuts against the roller brush 12 at an angle so as to smoothly introduce the sewage and debris scraped from the roller brush 12 into the guide area 432.

[0075] Specifically, during the cleaning process, most of the sewage and debris removed by the brush roller 22 will fall directly into the guide area 432 under its own gravity. A small portion of sewage and debris that deviates from the guide area 432 will be guided into the guide area 432 by the scraper 42, preventing them from falling back to the ground. The sewage and debris scraped off by the scraper 42 will enter the guide area 432 directly along the scraper 42, and finally be guided by the guide area 432 to converge into the sewage tank 41 through the water collection port. Therefore, the above structural design can guide sewage and debris into the sewage tank 41 and prevent sewage and debris from leaving the sewage tank 41, reducing the possibility of sewage and debris falling back to the ground and further improving the user experience.

[0076] See appendix Figure 1 - Appendix Figure 9 The top of the body 1 is provided with a hidden cavity 16 for accommodating the clean water tank 31. An opening 161 is provided on the side of the hidden cavity 16, and a protrusion 160 extending along the direction of the opening 161 is provided on the inner wall of the hidden cavity 16. A groove 310 is also installed on the outer wall of the clean water tank 31, which is slidably connected to and interference-fitted with the protrusion 160. The clean water tank 31 can enter and exit the hidden cavity 16 through the opening 161. The clean water tank 31 is provided with a water inlet 311 and a water outlet 312. The water inlet 311 protrudes from the hidden cavity 16 and has… The cover 3110 has a valve 313 with a rubber block 3131 and a water channel 3132 movably installed at the water outlet 312; the water supply unit 32 includes a connecting end 321, a water pump 322 and a spray pipe 323. The water outlet is installed on the body 1 and inserted into the water outlet 312. The spray pipe 323 is installed on the body 1 and has multiple spray holes 3230 corresponding to the roller brush 12. The water pump 322 is installed inside the body 1 and is connected to the connecting end 321 and the spray pipe 323 through a water pipe (not shown in the figure).

[0077] Specifically, during use, first remove the cover 3110 to open the water inlet 311, and then inject clean water or cleaning solution into the clean water tank 31 through the water inlet 311. After the clean water tank 31 is full, close the cover 3110 to close the water inlet 311. Under water pressure, the valve 313 moves outward, causing the rubber block 3131 to abut against the closed outlet 312 to prevent water from overflowing. Then, move the clean water tank 31 into the hidden cavity 16 through the movable port 161. During this process, the connecting end 321 is inserted into the outlet 312 and abuts against the valve. The nozzle 313 moves so that the rubber block 3131 moves away from the water outlet 312, ensuring that the water channel 3132 connects the inside of the clean water tank 31 and the connecting end 321. At this time, the water pump 322 is started to pump the water in the clean water tank 31 to the spray hole 3230 and spray the roller brush 12. The design of the movable port 161 facilitates the disassembly and maintenance of the clean water tank 31, while the cooperation of the protrusion 160 and the groove 310 gives the clean water tank 31 sliding damping, preventing the clean water tank 31 from easily falling out of the hidden cavity 16 and improving the installation stability.

[0078] It should be noted that the specific structure of the nozzle 323 varies, and not all of them will be listed in this utility model. In this embodiment, the nozzle 323 has a liquid channel 3231 inside that simultaneously connects to multiple nozzle holes, and the nozzle 323 has a water inlet pipe head 3232 outside that connects the liquid channel 3231 and the drain end of the water pump 322, so as to ensure that the water pump 322 can pump water smoothly. In addition, the manufacturer can build a battery in the body 1 or the handle 11 to power the water pump 322. The relevant technology is relatively common in the field, and it will not be described in detail in this embodiment.

[0079] See appendix Figure 1 - Appendix Figure 9The bottom of the machine body 1 is provided with a guide rail 17, which is located next to the roller brush 12 and extends along the length of the roller brush 12; the sewage tank 41 is provided with a guide block 413 that slides with the guide rail 17, and the sewage tank 41 is also fixedly connected to a second baffle 14 so that the sewage tank 41 and the machine body 1 can be disassembled from each other.

[0080] Specifically, under normal circumstances, the second baffle 14 abuts against the machine body 1, causing the transmission end 141 and the second rotating rod 142 to be respectively inserted into the linkage cylinder 212 and the brush roller 22. At this time, the guide block 413 is located on the guide rail 17, so that the sewage tank 41 is stably fixed below the machine body 1. When it is necessary to disassemble the sewage tank 41, first release the restriction of the locking part on the second baffle 14, and then pull the second baffle 14 to drive the sewage tank 41 to move outward along the length direction of the guide rail 17 to the outside. Therefore, the cooperation of the guide rail 17 and the guide block 413 makes the installation of the sewage tank 41 more stable, and the design of the sewage tank 41 being fixed to the second baffle 14 facilitates the simultaneous disassembly of the sewage tank 41 and the brush roller 22 and other components for cleaning and maintenance, further improving the ease of operation.

[0081] See appendix Figure 1 - Appendix Figure 9 Two roller brushes 12 are provided and distributed on two opposite sides of the body 1. The cleaning mechanism 2 is designed with two sets of roller brushes 12 corresponding to each other. The driving parts 21 of the two sets of cleaning mechanisms 2 are respectively connected to the two roller brushes 12 and drive the two roller brushes 12 to rotate in opposite directions. For ease of understanding, in this embodiment, the two roller brushes 12 are referred to as the first roller brush 12 and the second roller brush 12, and the brush rollers 22 in the two sets of cleaning mechanisms 2 are referred to as the first brush roller 22 and the second brush roller 22, respectively.

[0082] Specifically, during use, the difference in driving force between the two drive units 21 (specifically, the difference in torque between the two motors 211) needs to be adjusted to drive the machine body 1 to move back and forth. If it is necessary to control the machine body 1 to move forward, the driving force of the drive unit 21 corresponding to the second roller brush 12 is adjusted to be greater than the driving force of the drive unit 21 corresponding to the first roller brush 12 to ensure that the machine body 1 can move forward automatically. Conversely, if it is necessary to control the machine body 1 to move backward, the driving force of the drive unit 21 used to control the rotation of the second roller brush 12 is adjusted to be less than the driving force of the drive unit 21 used to control the rotation of the first roller brush 12 to ensure that the machine body 1 can move backward automatically.

[0083] In summary, during the forward and backward movement of the machine body 1, the two sets of drive units 21 drive the first roller brush 12 and the second roller brush 12 to rotate relative to each other to perform cleaning operations. The first brush roller 22 and the second brush roller 22 also rotate relative to each other to clean the sewage and debris on the first roller brush 12 and the second roller brush 12, thus improving cleaning efficiency. In addition, even if one of the roller brushes 12 is damaged, the other roller brush 12 can still be used normally, thereby ensuring that the cleaning operation can be carried out smoothly.

[0084] Furthermore, in an embodiment where the recycling unit 4 includes a wastewater tank 41 and scraper blades 42, two scraper blades 42 can be installed on both sides of the wastewater tank 41 to correspond one-to-one with the two roller brushes 12; for ease of understanding, in this embodiment the two scraper blades 42 are referred to as the first scraper blade 42 and the second scraper blade 42.

[0085] Specifically, during the back-and-forth movement of the machine body 1, the first scraper 42 and the second scraper 42 can respectively further clean the relatively rotating first roller brush 12 and the second roller brush 12; and when there are two scraper 42s, if scraper blades 422 are provided on the scraper 42, the two scraper blades 422 can be used to loosen large stains on the ground, so that the stains can be rolled away by the first roller brush 12 and the second roller brush 12, thereby further improving the cleaning efficiency.

[0086] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
