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

[0002] With social development and technological advancements, more and more smart devices are being applied to people's lives. Floor scrubbers, as cleaning devices that automatically wipe and clean floors, replace everyday cleaning tools such as mops, enabling daily periodic cleaning of hard floors and targeted cleaning at any time.

[0003] However, due to the structural limitations of existing floor scrubbers, their cleaning capabilities are limited, making it impossible to quickly remove stubborn stains from the floor. These stubborn stains require repeated cleaning or manual removal by the user, which affects the cleaning effect and work efficiency of the floor scrubber and fails to further reduce the user's labor time and intensity.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0048] See Figures 1 to 3 The embodiments of this application provide a cleaning device 100, specifically a floor scrubber for cleaning surfaces such as floors, including a floor brush structure 20, a handle 40, and a main body 60.

[0049] The floor brush structure 20 is placed on the ground for cleaning. One end of the handle 40 is connected to the floor brush structure 20, and the other end of the handle 40 has a grip for the user to hold, allowing the user to move the floor brush structure 20 on the ground. The main body 60 is located at the end of the handle 40 connected to the floor brush structure 20, and the main body 60 has a wastewater tank 61 connected to the floor brush structure 20 for storing wastewater generated during the cleaning process.

[0050] Furthermore, the floor brush structure 20 includes a main housing 21 and auxiliary wheels 29, a clean water tank 22, a roller brush 23, and a suction pipe mounted on the main housing 21. The main housing 21 is formed by splicing a first housing 212 and a second housing 214 together, serving to accommodate and fix the brush. The auxiliary wheels 29 are located at the rear of the main housing 21 to assist the movement of the floor brush structure 20. The clean water tank 22 is located at the top of the main housing 21 to provide cleaning water for the roller brush 23. The roller brush 23 is rotatably mounted at the front of the main housing 21 for rotating and cleaning the floor. The suction pipe is located inside the main housing 21, with its inlet facing the rear of the roller brush 23, for absorbing dirt from the roller brush 23. The outlet of the suction pipe connects to the wastewater tank 61 of the main body 60, allowing the dirt absorbed by the suction pipe to be stored in the wastewater tank 61.

[0051] Furthermore, in some embodiments, such as Figure 4 and Figure 5 As shown, the floor brush structure 20 also includes a scraper 24, which is installed on the main housing 21 and spaced apart on one side of the roller brush 23. The scraper 24 is used to scrape off residual water stains on the floor.

[0052] In the following embodiments, the forward direction of the brush structure 20 is defined as the first direction (i.e., Figure 1 The X direction in the middle), the length direction of the brush structure 20 is the second direction (i.e., Figure 2 The Y direction in the middle), the height direction of the floor brush structure 20 is the third direction (i.e. Figure 1 The first direction, the second direction, and the third direction intersect each other in the Z direction. In a preferred embodiment, the first direction, the second direction, and the third direction are perpendicular to each other.

[0053] As described in the background section, during routine and spot cleaning, dried stains often appear on the floor, such as dried rice grains, dried and sticky stains, and residual paint from renovations. Existing floor scrubbers require prolonged operation and repeated pushing and pulling to remove these stubborn stains. In some cases, it is even necessary for users to first separate the stubborn stains from the floor by hand or other tools before using the floor scrubber to remove them. This not only increases the time cost of cleaning work but also increases the labor intensity of the operators.

[0054] The main reason existing floor scrubbers cannot effectively clean stubborn stains is that these stains adhere too strongly to the floor, while the cleaning capacity of a floor scrubber is limited. The cleaning power of a floor scrubber primarily comes from the friction of the roller brush against the floor, and the scraper also plays a role. However, because the overall weight of the floor scrubber is fixed, the pressure it exerts on the floor is also constant. Therefore, the pressure applied by the roller brush and scraper is limited, thus restricting the cleaning ability. Furthermore, with the trend towards lightweight design, the overall weight of floor scrubbers is decreasing, further challenging their cleaning effectiveness.

[0055] To meet lightweight design requirements while ensuring good cleaning performance, some floor scrubbers employ a lowered center of gravity design. This reduces the overall weight of the scrubber while maintaining the friction between the brush and the floor. However, due to the limited overall weight of the scrubber and the fact that the rear wheels bear some of the pressure, it still cannot achieve the effect of quickly removing stubborn stains.

[0056] For the above technical issues, please refer to [link / reference needed]. Figures 4 to 7 The floor brush structure 20 of the floor scrubber of this application also includes a wiping component 25, which is rotatably connected to the main housing 21 and spaced apart on one side of the roller brush 23. The wiping component 25 can reciprocate in a controlled manner relative to the main housing 21.

[0057] Thus, in addition to the roller brush 23, the floor brush structure 20 also has a reciprocating wiping component 25. The wiping component 25 repeatedly rubs the floor, causing stubborn stains to be quickly separated from the floor, thereby improving the cleaning efficiency of the cleaning device 100 equipped with the floor brush structure 20, optimizing the cleaning effect of the cleaning device 100, and effectively reducing the user's working time and reducing the user's labor intensity.

[0058] Please continue reading. Figures 4 to 7 The scraper 24 includes a scraper body 241 and a scraping part 243. The scraper body 241 is an elongated structure extending along the second direction, and is formed of a hard material such as hard plastic, and is fixedly installed at the bottom of the main housing 21. The scraping part 243 is an elongated structure extending along the second direction, and is formed of a material such as soft plastic that can undergo elastic deformation. One end of the scraping part 243 is inserted into the edge of the scraper 24 mounting part facing the roller brush 23, and the other end of the scraping part 243 extends downward at an angle away from the main housing 21. The scraping part 243 is used to make close contact with the ground to scrape away residual water stains on the ground.

[0059] In some embodiments, the scraping part 243 is located on the moving path of the wiping member 25, so that the wiping member 25 can contact the scraping member 243 during reciprocating motion. The scraping member 243 can scrape away dirt on the wiping member 25 to keep the wiping member 25 clean at all times, effectively preventing dirt residue from affecting the stain removal effect. As a preferred embodiment, the scraping part 243 has a protrusion on the side facing the wiping member 25, which can contact the wiping member 25 to scrape away dirt on the wiping member 25.

[0060] In one specific embodiment, the wiping member 25 is rotatably connected to the scraping member body 241 of the scraping member 24. The scraping portion 243 extends between the roller brush 23 and the wiping member 25. The wiping member 25 reciprocates along a first direction while swinging back and forth about an axis extending along a second direction, thereby moving closer to or away from the roller brush 23. Figure 7 As shown, as it approaches the roller brush 23, the wiping member 25 can contact the scraping member 24 and continue to move toward the roller brush 23, thereby scraping away the dirt on it by the scraping member 24.

[0061] It is understood that the specific movement mode of the wiping member 25 is not limited. In some other embodiments, the wiping member 25 may move back and forth only along the first direction, or swing back and forth only around an axis extending along the second direction, both of which can achieve the effect of wiping away stubborn stains.

[0062] In some embodiments, the scraper body 241 of the scraper 24 is provided with a plurality of first mounting portions 2412, all of which are arranged at intervals along a second direction. Each first mounting portion 2412 is provided with a mounting groove extending along the second direction for mounting the wiping member 25.

[0063] Please see Figure 5 , Figure 8 as well as Figure 9 As shown, the erasing member 25 has an elongated structure, and the length direction of the erasing member 25 is parallel to the second direction. The erasing member 25 includes a connecting portion 252 and an erasing portion 254. The connecting portion 252 is formed of a material with high hardness, such as rubber, and is rotatably connected to the scraper 24. The erasing portion 254 is formed of a material with low hardness, such as rubber, and extends from the connecting portion 252 in a direction away from the main housing 21. The thickness of the erasing portion 254 gradually decreases from the end near the connecting portion 252 to the end away from the connecting portion 252.

[0064] As a preferred embodiment, the surface of the wiping part 254 facing the roller brush 23 is frosted or covered with protrusions. The protrusions can be in the shape of strips, dots, waves, etc., thereby increasing the friction between it and the ground and improving the cleaning effect.

[0065] The connecting portion 252 of the wiping member 25 is provided with a plurality of second mounting portions 2521 on the side surface facing the main housing 21. All the second mounting portions 2521 are arranged at intervals along the second direction. Each second mounting portion 2521 has a mounting shaft. Each mounting shaft is rotatably limited in a mounting groove on one side of the scraper 24, so that the wiping member 25 is rotatably connected to the scraper 24.

[0066] It is understood that the number of the first mounting part 2412 and the second mounting part 2521 is unlimited and can be set as needed to meet different requirements. Since the wiping part 25 and the scraping part 24 are rotatably connected by the mutual cooperation of the mounting groove and the mounting shaft, there is no need to set up extra parts, which simplifies the assembly method of the wiping part 25.

[0067] Please see Figures 10 to 13 In some embodiments, the floor brush structure 20 further includes a wiping drive assembly 26, which is mounted on the main housing 21 and drively connected to the wiping member 25. The wiping drive assembly 26 is used to drive the wiping member 25 to reciprocate relative to the main housing 21. Figure 7 As shown, when the wiping member 25 is at its extreme position closest to the roller brush 23, the wiping portion 254 bends and extends downward from the connecting portion 252 toward the direction of the roller brush 23. Figure 5 As shown, when the wiping member 25 is at the extreme position furthest from the roller brush 23, the wiping part 254 bends and extends downward from the connecting part 252 in a direction away from the roller brush 23.

[0068] Please continue reading. Figures 10 to 13 Specifically, the erase drive assembly 26 includes an erase drive component 261 and a linkage mechanism 263. The erase drive component 261 is connected to the eraser component 25 via the linkage mechanism 263. It is understood that the structure of the erase drive assembly 26 is not limited to this and can be configured as needed to meet different transmission requirements.

[0069] In one specific embodiment, the floor brush structure 20 further includes a drive unit mounting housing 27. The wiping drive unit 261 is fixed inside the main housing 21 through the drive unit mounting housing 27. The wiping drive unit 261 is a servo motor equipped with an encoder 2612, which has the characteristics of high control precision and fast response, and therefore can control the wiping component 25 to reciprocate rapidly. The output shaft of the wiping drive unit 261 is a D-type shaft or a double D-type shaft, which is connected to the linkage mechanism 263 for transmission. As a preferred embodiment, the output shaft of the wiping component 25 is located close to the middle position of the main housing 21 in the second direction, so that the two ends of the wiping component in the second direction are relatively stable under force.

[0070] Please combine Figure 11 , Figure 13 , Figure 14 as well as Figure 15As shown, the linkage mechanism 263 includes a first link 2632 and a second link 2634. The first link 2632 has a rod-like structure. One end of the first link 2632 is sleeved on the output shaft of the erasing drive 261 and is axially limited by a snap ring 265. The other end of the first link 2632 is rotatably connected to the second link 2634. The second link 2634 is roughly "V"-shaped, including a first end and a second end that are opposite to each other. The width of the second link 2634 gradually increases from the first end to the second end in the second direction. The first end of the second link 2634 is rotatably connected to the end of the first link 2632 away from the output shaft. The two opposite ends of the second end of the second link 2634 in the width direction are respectively rotatably connected to the erasing member 25.

[0071] Specifically, the connecting part 252 of the erasing component 25 has two third mounting parts 2523 on the side surface facing away from the main housing 21. The two third mounting parts 2523 are spaced apart along the second direction. The opposite ends of the second end of the second link 2634 in the width direction are rotatably connected to the two third mounting parts 2523 respectively through components such as pins.

[0072] Thus, the force output by the erasing drive 261 is transmitted to the erasing component 25 through the first link 2632 and the second link 2634. Since the width of the second link 2634 gradually increases from the first end connecting the first link 2632 to the second end connecting the erasing component 25, the force output by the erasing drive 261 is transmitted to the erasing component 25 along both ends of the second link 2634, so that the erasing component 25 is subjected to uniform force in the length direction, thereby ensuring the stability and reliability of the transmission.

[0073] In some embodiments, the main housing 21 has a limiting groove 214a, and the scraper body 241 of the scraper 24 has a communicating groove corresponding to the limiting groove 214a. One end of the first connecting rod 2632 is connected to the wiping drive 261, and the other end of the first connecting rod 2632 passes through the limiting groove 214a and connects to the communicating groove to the second connecting rod 2634. When the scraper 25 is in the extreme position, the first connecting rod 2632 abuts against the groove wall of the limiting groove 214a and cannot continue to move. The torque of the wiping drive 261 increases and reverses direction, thereby limiting the movement range of the scraper 25.

[0074] It is understandable that, since the rotation angle of the output shaft of the erasing drive 261 can be limited by the groove wall of the limiting groove 214a, the resolution requirement for the encoder 2612 can be relaxed or even eliminated, thereby reducing the cost of the erasing drive 261. In some other embodiments, the groove wall of the limiting groove 214a may not have a limiting effect on the linkage mechanism 263, but instead rely on the encoder 2612 to control the working state of the erasing drive 261, thereby preventing the limiting structure from deforming or breaking after long-term stress.

[0075] Please combine Figure 2 and Figure 4 The cleaning device 100 of this application also includes a wiping control button 41 and a control unit 28. The wiping control button 41 is installed on the grip of the handle 40, and the control unit 28 is installed in the floor brush structure 20. The wiping control button 41 is communicatively connected to the control unit 28, and the control unit 28 is communicatively connected to the wiping drive assembly 26. The wiping control button 41 sends a control signal to the control unit 28, and the control unit 28 controls the wiping drive assembly 26 to work according to the control signal.

[0076] Based on the different cleaning approaches users may have when facing stubborn stains, the cleaning device 100 of this application has an automatic wiping mode and a follow-up wiping mode. When the user is accustomed to cleaning in one place, they can choose the automatic wiping mode. When the user is accustomed to cleaning continuously and repeatedly, they can choose the follow-up wiping mode.

[0077] When the user presses the erasure control button 41, the control unit 28 receives the control signal and executes the automatic erasure mode. The erasure drive assembly 26 drives the erasure component 25 to reciprocate relative to the main housing 21 a preset number of times, thereby quickly erasing stains. For example, when the user presses the erasure control button 41, the erasure component 25 reciprocates relative to the main housing 21 10 times to erase stains. It is understood that the number of movements of the erasure component 25 can be set as needed and is not limited here.

[0078] When the user presses and holds the wiping control button 41, the control unit 28 receives the control signal and executes the follow-wiping mode. The wiping drive assembly 26 drives the wiping component 25 to reciprocate in the same direction as the cleaning device 100. Specifically, if the cleaning device 100 moves forward, the wiping component 25 moves towards the roller brush 23 to its limit position and then remains stationary; if the cleaning device 100 moves backward, the wiping component 25 moves away from the roller brush 23 to its limit position and then remains stationary. In this way, as the cleaning device 100 reciprocates, the wiping component 25 also reciprocates synchronously to wipe the floor back and forth.

[0079] The direction of movement of the cleaning device 100 can be identified by recognizing the assist wheel 29 of the cleaning device 100. Specifically, the cleaning device 100 is equipped with an assist wheel 29 and a hub motor for driving the assist wheel 29 to rotate. The hub motor is equipped with a speed sensor, so the control unit 28 can obtain the rotation direction of the assist wheel 29 through the speed sensor to identify the direction of movement of the cleaning device 100, and then control the direction of movement of the wiping member 25. In some other embodiments, the direction of movement of the cleaning device 100 can also be identified by setting other identification elements.

[0080] The automatic wiping mode can be used to quickly clean stains in a specific area, offering higher cleaning efficiency. However, it cannot effectively identify whether stains have been removed during the cleaning process; the wiping element 25 only stops operating after completing the preset cleaning program. The follow-wiping mode allows users to see the cleaning status after each wipe, improving the user experience, but its cleaning efficiency is relatively lower. Therefore, users can select different wiping modes according to their needs to achieve better cleaning results.

[0081] The aforementioned floor brush structure 20 and the cleaning device 100 equipped with it can not only use the roller brush 23 to clean the regular stains on the floor and use the scraper 24 to scrape off residual water stains, but also use the wiping member 25 to repeatedly wipe away stubborn stains on the floor, thereby effectively improving the cleaning effect and cleaning efficiency of the cleaning device 100, significantly reducing the household chores burden of users, and facilitating the further promotion of the cleaning device 100.

[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
