If any, 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 implementation method.

[0048] 1 to 3 , an embodiment of the present application provides a cleaning device 100 , specifically a floor scrubber for cleaning a floor or other cleaning surface, 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 the ground. One end of the handle 40 is connected to the floor brush structure 20, and the other end of the handle 40 is provided with a gripping portion for the user to hold. The user can drive the floor brush structure 20 to move on the ground through the handle 40. The main body 60 is provided at one end of the handle 40 connected to the floor brush structure 20, and the main body 60 is provided with a sewage tank 61 connected to the floor brush structure 20 for storing sewage generated during the cleaning process.

[0050] Furthermore, the floor brush structure 20 includes a main housing 21 and a power-assisting wheel 29, a clean water tank 22, a roller brush 23 and a sewage suction pipe installed on the main housing 21. Among them, the main housing 21 is formed by splicing a first housing 212 and a second housing 214 together, and is used to accommodate, fix, etc. The power-assisting wheel 29 is arranged at the rear of the main housing 21 to assist the movement of the floor brush structure 20. The clean water tank 22 is arranged at the top of the main housing 21 to provide cleaning water for the roller brush 23. The roller brush 23 is rotatably installed at the front of the main housing 21 to rotate and clean the floor. The sewage suction pipe is located in the main housing 21, and the inlet end of the sewage suction pipe faces the rear side of the roller brush 23, which is used to absorb the dirt on the roller brush 23. The outlet end of the sewage suction pipe is connected to the sewage tank 61 of the main body 60, and the dirt absorbed by the sewage suction pipe can enter the sewage tank 61 for storage.

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

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

[0053] As described in the background technology, during daily cleaning and fixed-point cleaning, dry stains often appear on the ground, such as dry rice grains, dry sticky stains, paint residue after decoration, etc. Existing floor scrubbers need to run for a long time and push and pull repeatedly to clean the above stubborn stains. In some cases, users even need to separate the stubborn stains from the ground with their hands or other tools in advance, and then use the floor scrubber to remove the stubborn stains. This not only increases the time cost of cleaning work, but also increases the labor intensity of operators.

[0054] The reason why existing floor scrubbers cannot effectively clean stubborn stains is mainly because the stubborn stains have too strong adhesion to the ground, while the cleaning ability of floor scrubbers is limited. The cleaning ability of floor scrubbers mainly comes from the friction of the roller brush on the ground, and the scraper also has a certain cleaning effect. However, since the overall weight of the floor scrubber is constant, the pressure it exerts on the ground is also constant, so the pressure exerted on the ground by the roller brush and the scraper is limited, resulting in a certain limitation on the cleaning ability of the floor scrubber. Moreover, with the trend of lightweight design of floor scrubbers, the overall weight of floor scrubbers is decreasing, so the cleaning effect of floor scrubbers is further challenged.

[0055] In order to meet the requirements of lightweight design and ensure that the floor scrubber has a good cleaning effect, some floor scrubbers adopt a design method of lowering the center of gravity, which can not only reduce the overall weight of the floor scrubber, but also ensure the friction of the roller brush on the ground. However, due to the limited overall weight of the floor scrubber and the fact that the rear wheels of the floor scrubber bear part of the pressure, it is still impossible to quickly remove stubborn stains.

[0056] Regarding the above technical issues, please continue to refer to Figures 4 to 7. The floor brush structure 20 of the floor scrubber of the present application also includes an erasing member 25, which is rotatably connected to the main shell 21 and is spaced apart on one side of the roller brush 23. The erasing member 25 can be controlled to reciprocate relative to the main shell 21.

[0057] In this way, the floor brush structure 20 is provided with a reciprocating erasing member 25 on the basis of the roller brush 23. The erasing member 25 repeatedly rubs the ground, so that stubborn stains are quickly separated from the ground, thereby improving the cleaning efficiency of the cleaning device 100 provided 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 to refer to Figures 4 to 7. The scraper 24 includes a scraper body 241 and a scraper portion 243. The scraper body 241 is a long strip structure extending along the second direction. The scraper body 241 is formed of a hard material such as hard plastic and is fixedly installed at the bottom of the main housing 21. The scraper portion 243 is a long strip structure extending along the second direction, and is formed of a material that can undergo elastic deformation such as soft plastic. One end of the scraper portion 243 is plugged into the edge of one side of the installation portion of the scraper 24 facing the roller brush 23, and the other end of the scraper portion 243 extends downwardly in a direction away from the main housing 21. The scraper portion 243 is used to be in close contact with the ground to scrape off the residual water stains on the ground.

[0059] Further, in some embodiments, the scraping portion 243 is located on the moving path of the erasing member 25, so that the erasing member 25 can contact the scraping member 24 during the reciprocating motion, and the scraping member 24 can scrape off the dirt on the erasing member 25 to keep the erasing member 25 always clean, effectively preventing dirt from remaining and affecting the stain erasing effect. As a preferred embodiment, the scraping portion 243 is provided with a protrusion on the side facing the erasing member 25, and the protrusion can contact the erasing member 25 to scrape off the dirt on the erasing member 25.

[0060] Specifically, in one embodiment, the erasing member 25 is rotatably connected to the scraping member body 241 of the scraping member 24, and the scraping portion 243 extends between the roller brush 23 and the erasing member 25. The erasing member 25 reciprocates along the first direction and swings back and forth around an axis extending along the second direction, thereby approaching or moving away from the roller brush 23. As shown in FIG7, in the process of approaching the roller brush 23, the erasing member 25 may contact the scraping member 24 and continue to move toward the roller brush 23, so that the dirt thereon is scraped off by the scraping member 24.

[0061] It can be understood that the specific movement mode of the erasing member 25 is not limited. In some other embodiments, the erasing member 25 can only move back and forth along the first direction, or only swing back and forth around an axis extending along the second direction, both of which can play the role of erasing 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 the second direction, and each first mounting portion 2412 is provided with a mounting groove extending along the second direction for mounting the erasing member 25 .

[0063] Please refer to FIG. 5 , FIG. 8 and FIG. 9 , the erasing member 25 is in a long strip 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 such as rubber with a relatively high hardness, and is rotatably connected to the scraping member 24. The erasing portion 254 is formed of a material such as rubber with a relatively low hardness, and is bent and extended from the connecting portion 252 in a direction away from the main housing 21, and the thickness of the erasing portion 254 gradually decreases from one end close to the connecting portion 252 to the other end away from the connecting portion 252.

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

[0065] A plurality of second mounting portions 2521 are provided on a side surface of the connecting portion 252 of the erasing member 25 facing the main shell 21, and all the second mounting portions 2521 are arranged at intervals along the second direction. Each second mounting portion 2521 has a mounting axis, and each mounting axis can be rotatably limited in a mounting groove on one side of the scraping member 24, so that the erasing member 25 can be rotatably connected to the scraping member 24.

[0066] It is understandable that the number of the first mounting portion 2412 and the second mounting portion 2521 is not limited and can be set as needed to meet different requirements. Since the erasing member 25 and the scraping member 24 are rotatably connected by the mutual cooperation of the mounting groove and the mounting shaft, no redundant parts are required, which simplifies the assembly method of the erasing member 25.

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

[0068] Please continue to refer to Figures 10 to 13. Specifically, the erasing drive assembly 26 includes an erasing drive member 261 and a connecting rod mechanism 263. The erasing drive member 261 is connected to the erasing member 25 through the connecting rod mechanism 263. It can be understood that the structure of the erasing drive assembly 26 is not limited thereto and can be configured as needed to meet different transmission requirements.

[0069] Specifically in one embodiment, the floor brush structure 20 also includes a drive member mounting shell 27, and the erasing drive member 261 is fixed inside the main housing 21 through the drive member mounting shell 27. The erasing drive member 261 is a servo motor provided with an encoder 2612, which has the characteristics of high control accuracy and fast response, so that the erasing member 25 can be controlled to reciprocate quickly. The output shaft of the erasing drive member 261 is a D-type shaft or a double D-type shaft, which is connected to the connecting rod mechanism 263 in transmission. As a preferred embodiment, the output shaft of the erasing member 25 is close to the middle position of the main housing 21 in the second direction, so that the force on both ends of the wiping member in the second direction is relatively stable.

[0070] Please refer to Figures 11, 13, 14 and 15, the connecting rod mechanism 263 includes a first connecting rod 2632 and a second connecting rod 2634. The first connecting rod 2632 is a rod-shaped structure, one end of which is sleeved on the output shaft of the erasing drive member 261 and is axially limited by a retaining spring 265, and the other end of the first connecting rod 2632 is rotatably connected to the second connecting rod 2634. The second connecting rod 2634 is generally in a "human" shape, including a first end and a second end that are arranged oppositely, and the width of the second connecting rod 2634 in the second direction gradually increases from the first end to the second end, the first end of the second connecting rod 2634 is rotatably connected to the end of the first connecting rod 2632 away from the output shaft, and the opposite end ends of the second end of the second connecting rod 2634 in the width direction are rotatably connected to the erasing member 25 respectively.

[0071] Specifically, two third mounting portions 2523 are provided on the side surface of the connecting portion 252 of the erasing member 25 facing away from the main shell body 21. The two third mounting portions 2523 are spaced apart along the second direction. The opposite end portions of the second end of the second connecting rod 2634 in the width direction are rotatably connected to the two third mounting portions 2523 through components such as pins.

[0072] In this way, the force output by the erasing driving member 261 is transmitted to the erasing member 25 through the first connecting rod 2632 and the second connecting rod 2634. Since the width of the second connecting rod 2634 gradually increases from the first end connected to the first connecting rod 2632 to the second end connected to the erasing member 25, the force output by the erasing driving member 261 is transmitted to the erasing member 25 along the two ends of the second connecting rod 2634, so that the erasing member 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 is provided with a limiting groove 214a, the scraper body 241 of the scraper 24 is provided with a connecting groove corresponding to the limiting groove 214a, one end of the first connecting rod 2632 is connected to the erasing driving member 261, and the other end of the first connecting rod 2632 passes through the limiting groove 214a and is connected to the connecting groove with the second connecting rod 2634. When the erasing member 25 is located at the limit position, the first connecting rod 2632 abuts against the groove wall of the limiting groove 214a and cannot continue to move, and the torque of the erasing driving member 261 increases and reverses, thereby limiting the moving range of the erasing member 25.

[0074] It can be understood that, since the rotation angle of the output shaft of the erasing drive member 261 can be limited by the groove wall of the limiting groove 214a, the resolution requirement of the encoder 2612 can be relaxed or even the encoder 2612 can be eliminated, thereby reducing the cost of the erasing drive member 261. In some other embodiments, the groove wall of the limiting groove 214a may not have a limiting effect on the connecting rod mechanism 263, but rely on the encoder 2612 to control the working state of the erasing drive member 261, thereby preventing the limiting structure from being deformed, broken, etc. after being subjected to long-term force.

[0075] Please combine Figures 2 and 4. The cleaning device 100 of the present application also includes an erasing control button 41 and a control unit 28. The erasing control button 41 is installed on the holding portion of the handle 40, and the control unit 28 is installed in the floor brush structure 20. The erasing control button 41 and the control unit 28, and the control unit 28 and the erasing drive component 26 are respectively communicated and connected. The erasing control button 41 sends a control signal to the control unit 28, and the control unit 28 controls the erasing drive component 26 to work according to the control signal.

[0076] Based on the different cleaning ideas of users when facing stubborn stains, the cleaning device 100 of the present application has an automatic erasing mode and a follow-up erasing mode. When the user is accustomed to using a stationary cleaning method, the automatic erasing mode can be selected. When the user is accustomed to using a continuous reciprocating cleaning method, the follow-up erasing mode can be selected.

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

[0078] When the user long presses the erasing control button 41, the control unit 28 receives the control signal to execute the follow-up erasing mode, and the erasing drive assembly 26 drives the erasing member 25 to follow the forward and backward movement of the cleaning device 100 to reciprocate. Specifically, if the cleaning device 100 moves forward, the erasing member 25 moves toward the direction close to the roller brush 23 to the extreme position and then remains stationary; if the cleaning device 100 moves backward, the erasing member 25 moves toward the direction away from the roller brush 23 to the extreme position and then remains stationary. In this way, as the cleaning device 100 reciprocates, the erasing member 25 also reciprocates synchronously to reciprocate and wipe the ground.

[0079] The moving direction of the cleaning device 100 can be identified by identifying the power-assisted wheel 29 of the cleaning device 100. Specifically, the cleaning device 100 is provided with a power-assisted wheel 29 and a hub motor for driving the power-assisted wheel 29 to rotate, and the hub motor is provided with a speed sensor, so the control unit 28 can obtain the rotation direction of the power-assisted wheel 29 through the speed sensor to identify the moving direction of the cleaning device 100, and then control the moving direction of the erasing member 25. In some other embodiments, the moving direction of the cleaning device 100 can also be identified by setting other identification elements.

[0080] The automatic erasing mode can be used to quickly remove stains in a specific area, which has a higher cleaning efficiency, but it cannot effectively identify whether the stains have been removed during the cleaning process. The erasing member 25 can only end the action after completing the preset cleaning program. The follow-up erasing mode allows the user to see the cleaning status after each erasure, thereby improving the user experience, but the cleaning efficiency is relatively low. Therefore, the user can select different erasing modes according to needs to achieve better cleaning effects.

[0081] The above-mentioned floor brush structure 20 and the cleaning device 100 equipped with the same can not only use the roller brush 23 to clean the common stains on the floor and use the scraper 24 to scrape off the residual water stains, but also use the erasing member 25 to reciprocately wipe the stubborn stains on the floor, thereby effectively improving the cleaning effect and cleaning efficiency of the cleaning device 100, significantly reducing the user's housework burden, and facilitating the further promotion of the cleaning device 100.

[0082] 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.

[0083] 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.
