The cleaning robots that have emerged can liberate people from household cleaning work, effectively reduce people’s workload in household cleaning, and alleviate people’s fatigue during the process of household cleaning.

[0003] Some robots in the related art have basically achieved sweeping and vacuuming functions. To further enhance the automatic mopping function, cleaning solutions that use roller mops and scrapers for self-cleaning have also emerged.

[0026] In one embodiment, the first cleaning roller is located in front of the second cleaning roller along the cleaning direction; the cleaning mechanism further includes a waterway plate, which is disposed on the mounting seat and is used to guide water to the first cleaning roller and the second cleaning roller;

[0027] The average amount of water provided by the waterway plate to the first cleaning roller per unit time is greater than the average amount of water provided by the waterway plate to the second cleaning roller per unit time.

[0028] In one embodiment, the ratio of the average amount of water provided by the waterway plate to the first cleaning roller per unit time to the average amount of water provided by the waterway plate to the second cleaning roller per unit time is in the range of 1.5:1 to 3:1.

[0029] In one embodiment, along the cleaning direction, the first cleaning roller is located in front of the second cleaning roller; and the water absorption rate of the first cleaning roller is smaller than the water absorption rate of the second cleaning roller.

[0030] In one embodiment, the first scraping member has a first scraping contact surface, which contacts the first cleaning roller and is tangent to the outer surface of the first cleaning roller;

[0041] The above-mentioned cleaning mechanism and cleaning device, when the first cleaning roller and the second cleaning roller are worn out after long-term use, the elastic force of the first elastic member can be used to ensure that the first scraping member is always kept in contact with the first cleaning roller, and the elastic force of the second elastic member can be used to ensure that the second scraping member is always kept in contact with the second cleaning roller. Therefore, the first cleaning roller and the second cleaning roller can always be respectively acted upon by the first scraping member and the second scraping member to scrape off sewage, excess water or other impurities, thereby reducing the amount of sewage remaining on the first cleaning roller and the second cleaning roller, thereby reducing water stains on the surface to be cleaned and improving the cleaning effect.

[0042] In addition, it should be pointed out that in actual use, when the wear speed of the first cleaning roller and the second cleaning roller is different, the second cleaning roller may wear faster and its diameter may be smaller than that of the first cleaning roller. However, because the second scraper and the first scraper are independently arranged, the movement of the second scraper is not affected by the first scraper, so that the second scraper can maintain contact with the second cleaning roller and ensure that the second cleaning roller can reach an ideal wet state, reducing the generation of water stains.

[0043] Moreover, when X1<X2, that is, the second scraping contact portion is pressed more tightly against the corresponding cleaning roller than the first scraping contact portion, so that more sewage and the like on the second cleaning roller can be scraped off, while the first cleaning roller relatively retains more water. Therefore, the first cleaning roller can wet the surface to be cleaned by rotation, and the second cleaning roller can wipe the wetted surface to be cleaned by rotation, further improving the stain removal ability of the surface to be cleaned.

DETAILED DESCRIPTION

[0053] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0054] In the description of this application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0055] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0056] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connected," "fixed," etc., should be interpreted broadly. For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0057] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is described as being "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is described as being "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0058] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. 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 embodiment.

[0059] As mentioned in the background, the robot in the related art uses a self-cleaning solution that combines a roller mop with a scraper. In practice, after the robot activates its cleaning function, it continuously moistens the roller mop with a clean water tank and uses the scraper to contact the roller mop, squeezing out dirty water from the roller mop, which is then collected in the dirty water chamber, thereby cleaning the floor or other surface to be cleaned.

[0060] However, after long-term use, the roller mop will wear out, resulting in the scraper and the roller mop no longer being in contact, causing the scraper to be unable to squeeze out the dirty water on the roller mop, and the amount of residual dirty water on the roller mop will increase, which will lead to more water stains on the surface to be cleaned and poor cleaning effect.

[0061] In order to solve the problem that long-term use of roller mops causes increased water stains on the surface to be cleaned and the cleaning effect deteriorates, related technologies have adopted wear-resistant roller mops or solutions that require users to replace scrapers regularly, but both require manual intervention and cannot achieve automatic adjustment of the robot.

[0062] Therefore, the present application designs a cleaning mechanism and cleaning equipment that can automatically adjust the scraper so that the scraper can maintain contact with the roller mop, thereby solving the problem of increased water stains on the surface to be cleaned and poor cleaning effect after long-term use of the roller mop.

[0063] See Figures 1 to 5 One embodiment of the present application provides a cleaning mechanism 100, comprising a mounting base 10, a first cleaning roller 20, a second cleaning roller 30, and a first scraping member 40 and a second scraping member 50. The cleaning mechanism 100 of the embodiment of the present application can be part of a cleaning device, detachably connected to a main unit of the cleaning device. For example, the cleaning mechanism 100 can serve as the cleaning head of a handheld floor scrubber or mop. In other embodiments, the cleaning mechanism 100 can also function as a separate entity to achieve automatic cleaning functions, such as a cleaning robot, further comprising a transmission mechanism, a controller, and other structures.

[0064] The first cleaning roller 20 and the second cleaning roller 30 are both rotatably mounted on the mounting base 10 around their own axes, and are spaced apart from each other along the cleaning direction X.

[0065] The mounting base 10 is a base structure capable of mounting components. The mounting base 10 can be block-shaped, flat, or a bracket structure. Specifically, in the embodiment of the present application, the mounting base 10 includes a connecting portion 11 and mating portions 12 connected to both sides of the connecting portion 11. Each mating portion 12 extends in an arc shape away from the connecting portion 11. The first cleaning roller 20 and the second cleaning roller 30 can be mounted on the inner sides of the two mating portions 12, respectively. In this way, a mating gap can be formed between the first cleaning roller 20 and the mating portion 12, and between the second cleaning roller 30 and the mating portion 12. The mating portion 12 not only protects the first cleaning roller 20 and the second cleaning roller 30, but also blocks water that is thrown outward by the first cleaning roller 20 and the second cleaning roller 30 during the cleaning process. In addition, if the cleaning mechanism 100 also has a dust collection function, the mating gap can also ensure that there is sufficient suction force between the first cleaning roller 20 and the second cleaning roller 30 and the mounting base 10 to absorb dust, sewage, etc.

[0066] The cleaning direction X is the moving direction of the cleaning mechanism 100 , and specifically refers to the forward cleaning direction of the cleaning mechanism 100 .

[0067] The first cleaning roller 20 and the second cleaning roller 30 can both rotate around their own axes under the driving action of the driving mechanism. In the embodiment of the present application, the arrangement of the first cleaning roller 20 and the second cleaning roller 30 is adopted, which can not only improve the cleaning efficiency and the cleaning speed, but also the functions of the first cleaning roller 20 and the second cleaning roller 30 are different. When the first cleaning roller 20 is located in front of the second cleaning roller 30 along the cleaning direction X, the function of the first cleaning roller 20 is to wet the surface to be cleaned by rotation, while the function of the second cleaning roller 30 is to wipe the wetted surface to be cleaned by rotation. In this way, the stain removal ability of the surface to be cleaned can be further improved.

[0068] The first and second scraping members 40, 50 are both mounted on the mounting base 10 and are capable of contacting the first and second cleaning rollers 20, 30. The first and second scraping members 40, 50 are components capable of scraping dirt off components. In the embodiment of the present application, the first scraping member 40 is capable of scraping off sewage, excess water, or other impurities from the first cleaning roller 20, while the second scraping member 50 is capable of scraping off sewage, excess water, or other impurities from the second cleaning roller 30. Dirt scraped off by the first and second scraping members 40, 50 is recovered by a recovery mechanism on the cleaning mechanism 100. This recovery mechanism may include a dirt receiving member, a dirt suction pipe, a dirt tank, and a vacuum pump. The dirt tank generates negative pressure via the vacuum pump, and the dirt tank is connected to the dirt receiving member via the dirt suction pipe. Thus, dirt within the dirt receiving member can be vacuum-sucked through the dirt suction pipe into the dirt tank for collection. The dirt in the dirt tank can then be cleaned and discharged by the user or automatically by the base station.

[0069] It should be noted that, in order to achieve a better scraping effect, the first scraping member 40 generally has a certain interference fit with the first cleaning roller 20, so that the first scraping member 40 can abut against the surface of the first cleaning roller 20 and smoothly scrape away the scraped dirty water, excess water, or other impurities on the first cleaning roller 20. Similarly, the second scraping member 50 has a certain interference fit with the second cleaning roller 30, so that the second scraping member 50 can abut against the surface of the second cleaning roller 30 and smoothly scrape away the scraped dirty water, excess water, or other impurities on the second cleaning roller 30.

[0070] In the embodiment of the present application, both the first scraper 40 and the second scraper 50 are movably mounted on the mounting base 10. That is, the first scraper 40 and the second scraper 50 are not fixed to the mounting base 10, but are movable relative to the first cleaning roller 20 and the second cleaning roller 30 on the mounting base 10. Therefore, the interference fit between the first scraper 40 and the first cleaning roller 20, and between the second scraper 50 and the second cleaning roller 30, can be adjusted according to actual conditions. Therefore, when the first cleaning roller 20 and the second cleaning roller 30 become worn due to long-term use, the first scraper 40 and the second scraper 50 can be adjusted to maintain contact with the first cleaning roller 20 and the second cleaning roller 30, respectively, thereby reducing the amount of residual sewage on the first cleaning roller 20 and the second cleaning roller 30, thereby reducing water stains on the surface to be cleaned and improving the cleaning effect.

[0071] Please refer again Figures 2 to 5 Specifically, in some embodiments of the present application, the first scraping member 40 can rotate around the first axis relative to the mounting base 10.

[0072] When the first scraping member 40 rotates about the first axis relative to the mounting base 10, it can move closer to or farther away from the first cleaning roller 20 in the rotational direction, thereby simultaneously adjusting the interference fit between the first cleaning roller 20 and the first scraping member 40. This rotation method is simple and, compared to a translation method, occupies less space.

[0073] Likewise, the second scraping member 50 can rotate relative to the mounting seat 10 around the second axis.

[0074] When the second scraping member 50 rotates about the second axis relative to the mounting base 10, it can move closer to or farther away from the second cleaning roller 30 in the rotational direction, thereby simultaneously adjusting the interference fit between the second cleaning roller 30 and the second scraping member 50. This rotation method is simple and, compared to a translation method, occupies less space.

[0075] Of course, the first scraping member 40 can rotate relative to the mounting seat 10 around the first axis, and the second scraping member 50 can rotate relative to the mounting seat 10 around the second axis.

[0076] In order to achieve automatic adjustment of the interference fit between the first scraping member 40 and the first cleaning roller 20 and the automatic adjustment of the interference fit between the second scraping member 50 and the second cleaning roller 30, in an embodiment of the present application, the cleaning mechanism 100 further includes a first elastic member 60 and a second elastic member 70. The first elastic member 60 is disposed between the mounting base 10 and the first scraping member 40 and is configured to provide an elastic force F1 that keeps the first scraping member 40 in contact with the first cleaning roller 20. The second elastic member 70 is disposed between the mounting base 10 and the second scraping member 50 and is configured to provide an elastic force F2 that keeps the second scraping member 50 in contact with the second cleaning roller 30.

[0077] The first elastic member 60 and the second elastic member 70 are capable of elastic deformation under the action of external force and have elastic restoring force to automatically restore the elastic deformation.

[0078] Therefore, when the first cleaning roller 20 and the second cleaning roller 30 are worn out after long-term use, the elastic force of the first elastic member 60 can be used to keep the first scraping member 40 in contact with the first cleaning roller 20 at all times, and the elastic force of the second elastic member 70 can be used to keep the second scraping member 50 in contact with the second cleaning roller 30 at all times. Therefore, the first cleaning roller 20 and the second cleaning roller 30 can always be respectively acted upon by the first scraping member 40 and the second scraping member 50 to scrape off sewage, excess water or other impurities, thereby reducing the amount of sewage remaining on the first cleaning roller 20 and the second cleaning roller 30, thereby reducing water stains on the surface to be cleaned and improving the cleaning effect.

[0079] In addition, it should be pointed out that in actual use, when the wear speed of the first cleaning roller 20 and the second cleaning roller 30 is different, it is possible that the second cleaning roller 30 wears faster and its diameter is smaller than that of the first cleaning roller 20. However, because the second scraping member 50 and the first scraping member 40 are independently arranged separately, the movement of the second scraping member 50 is not affected by the first scraping member 40, so that the second scraping member 50 can maintain contact with the second cleaning roller 30 and ensure that the second cleaning roller 30 can reach an ideal wet state, reducing the generation of water stains.

[0080] In some embodiments, the first axis is parallel to the axis of the first cleaning roller 20 .

[0081] The parallel arrangement ensures that the distance from any position of the first rotating shaft to the surface of the first cleaning roller 20 in a direction perpendicular to the first rotating shaft remains consistent, thereby balancing the force between the first scraping member 40 and the first cleaning roller 20 and improving the reliability of scraping.

[0082] Likewise, the second axis may also be parallel to the axis of the second cleaning roller 30 .

[0083] In this way, the distance from any position of the second rotating shaft to the surface of the first cleaning roller 20 in the direction perpendicular to the second rotating shaft can be kept consistent, thereby balancing the force between the second scraping member 50 and the second cleaning roller 30 and improving the reliability of scraping.

[0084] Furthermore, the first axis coincides with the second axis.

[0085] When the first axis coincides with the second axis, the first scraper 40 and the second scraper 50 can share the same axis, thereby shortening the distance between the first scraper 40 and the second scraper 50 and further reducing the space occupied by the first scraper 40 and the second scraper 50.

[0086] Specifically, a rotating shaft 13 having a first axis and a second axis is fixed on the mounting base 10 , one end of the first scraping member 40 has a first shaft hole 41 , one end of the second scraping member 50 has a second shaft hole 51 , and the rotating shaft 13 passes through the first shaft hole 41 and the second shaft hole 51 .

[0087] Since the rotating shaft 13 is fixed to the mounting base 10, when the rotating shaft 13 passes through the first and second shaft holes 41, 51 and engages with the first and second shaft holes 41, 51, the first scraping member 40 can rotate about the rotating shaft 13. At the same time, the second scraping member 50 can also rotate about the rotating shaft 13. Therefore, the first and second scraping members 40, 50 can rotate simultaneously. This structure is simple and the rotational installation is reliable.

[0088] In some embodiments, the number of the first shaft hole 41 and the second shaft hole 51 can be multiple, and the multiple first shaft holes 41 and the second shaft holes 51 are spaced apart from each other along the extension direction of the rotating shaft 13. A second shaft hole 51 is provided between every two adjacent first shaft holes 41, and a first shaft hole 41 is provided between every two adjacent second shaft holes 51. The staggered arrangement of the first shaft holes 41 and the second shaft holes 51 along the extension direction of the rotating shaft 13 can improve the uniformity of the force applied to the first scraping member 40 and the second scraping member 50 at the position of the rotating shaft 13.

[0089] In some embodiments, the rotating shaft 13 can be a single piece or divided into multiple sections to mate with multiple first shaft holes 41 and second shaft holes 51. Preferably, the rotating shaft 13 is divided into two sections, specifically a first rotating shaft and a second rotating shaft, with the first rotating shaft mate with at least two first shaft holes 41 and at least two second shaft holes 51, and the second rotating shaft mates with at least two first shaft holes 41 and at least two second shaft holes 51. Because the rotating shaft 13 is relatively long, the multiple sections can improve the structural strength of the rotating shaft 13 and reduce the difficulty of assembly when mating with multiple first shaft holes 41 and second shaft holes 51.

[0090] It should be noted that, in other embodiments, the first axis may not coincide with the second axis, but may maintain a certain spacing distance therebetween. Specifically, the two may be spaced apart from each other in a direction perpendicular to the first axis or the second axis.

[0091] Combine Figure 6 and Figure 7 In some embodiments, the first scraping member 40 includes a first extreme position and a second extreme position during the rotation process. When the first scraping member 40 is at the first extreme position, the first scraping member 40 is against the mounting seat 10. When the first scraping member 40 is at the second extreme position, the first scraping member 40 is against the second scraping member 50.

[0092] When the first rotation axis of the first scraper 40 and the second rotation axis of the second scraper 50 coincide, the first scraper 40 and the second scraper 50 are very close to each other. Therefore, position limiting can be achieved more conveniently through the abutment between the first scraper 40 and the second scraper 50. Since the mounting base 10 serves as a fixed structure, limiting the position of the first scraper 40 through the mounting base 10 is also very reliable.

[0093] Specifically, the first limit position referred to here is the uppermost limit position of the first scraping member 40 along the vertical direction, and the second limit position is the lowermost limit position of the second scraping member 50 along the vertical direction.

[0094] Similarly, the second scraper 50 includes a third extreme position and a fourth extreme position during the rotation process. When the second scraper 50 is at the third extreme position, the second scraper 50 abuts against the mounting seat 10. When the second scraper 50 is at the second extreme position, the first scraper 40 abuts against the second scraper 50.

[0095] When the first rotation axis of the first scraper 40 and the second rotation axis of the second scraper 50 coincide, the first scraper 40 and the second scraper 50 are very close to each other. Therefore, position limiting can be achieved more conveniently through the abutment between the first scraper 40 and the second scraper 50. Since the mounting base 10 serves as a fixed structure, limiting the position of the second scraper 50 through the mounting base 10 is also very reliable.

[0096] In some embodiments, the number of the first elastic members 60 may include at least two, for example, three, four, or six, and all of the first elastic members 60 are spaced apart from each other along the first direction, wherein the first direction is parallel to the axis direction of the first cleaning roller 20. Similarly, the number of the second elastic members 70 may include at least two, for example, three, four, or six, and all of the second elastic members 70 are spaced apart from each other along the first direction, wherein the first direction is parallel to the axis direction of the second cleaning roller 30.

[0097] By arranging all first elastic members 60 spaced apart along the first direction, the elastic force applied by the first elastic members 60 to the first scraping member 40 can be uniform, the force on the first scraping member 40 is balanced, and the contact between the first scraping member 40 and the first cleaning roller 20 is comprehensive and stable, thereby improving the scraping effect. By arranging all second elastic members 70 spaced apart along the first direction, the elastic force applied by the second elastic members 70 to the second scraping member 50 can be uniform, the force on the second scraping member 50 is balanced, and the contact between the second scraping member 50 and the second cleaning roller 30 is comprehensive and stable, thereby improving the scraping effect.

[0098] Furthermore, the first scraping member 40 has a first central axis parallel to the first direction, and all of the first elastic members 60 are disposed on the first central axis. When all of the first elastic members 60 are disposed on the first central axis of the scraping member 40, the force applied to the first scraping member 40 along both sides of the first central axis can be uniform, thereby maintaining stable contact between the first scraping member 40 and the first cleaning roller 20.

[0099] In other embodiments, all first elastic members 60 may be symmetrically distributed relative to the first central axis. In this way, the first scraping member 40 is evenly stressed along both sides of the first central axis, thereby maintaining stable contact between the first scraping member 40 and the first cleaning roller 20.

[0100] Similarly, the second scraping member 50 has a second central axis parallel to the first direction, and all the second elastic members 70 are arranged on the second central axis. In this way, the force on both sides of the second scraping member 50 along the second central axis can be uniform, thereby ensuring that the second scraping member 50 can maintain stable contact with the second cleaning roller 30.

[0101] In other embodiments, all second elastic members 70 may be symmetrically distributed relative to the second central axis. In this way, the second scraping member 50 is evenly stressed along both sides of the second central axis, thereby maintaining stable contact between the second scraping member 50 and the second cleaning roller 30.

[0102] In some embodiments, the elastic force exerted by all the first elastic members 60 on the first scraping member 40 ranges from 5 Newtons to 25 Newtons.

[0103] The elastic force exerted by all first elastic members 60 on the first scraping member 40 ranges from 5 Newtons to 25 Newtons. This means that when all first elastic members 60 are compressed to their shortest length, with the first scraping member 40 at its topmost position, the elastic force exerted by all first elastic members 60 on the first scraping member 40 does not exceed 25 Newtons. When all first elastic members 60 are compressed to their longest length, with the first scraping member 40 at its bottommost position, the elastic force exerted by all first elastic members 60 on the first scraping member 40 is no less than 5 Newtons. Within this range, the first scraping member 40 can consistently maintain a certain interference fit with the first cleaning roller 20 during initial use and subsequent wear, thereby improving scraping and, consequently, cleaning performance.

[0104] Similarly, the elastic force exerted by all the second elastic members 70 on the second scraping member 50 is in the range of 5 Newtons to 25 Newtons. Within this range, the second scraping member 50 can always maintain a certain interference fit with the first cleaning roller 20 during the initial use and later wear of the first cleaning roller 20, thereby improving the scraping effect and thus the cleaning effect.

[0105] In the embodiment of the present application, the first elastic member 60 and the second elastic member 70 are specifically springs. In other embodiments, they can be replaced by elastic structures, such as rubber. In addition, when the first scraping member 40 and the second scraping member 50 are able to rotate relative to the mounting base 10, the first elastic member 60 and the second elastic member 70 can also be torsion springs.

[0106] As described above, along the cleaning direction X, the first cleaning roller 20 is located in front of the second cleaning roller 30, and the two cleaning rollers have different functions. The first cleaning roller 20 wets the surface to be cleaned by rotating, while the second cleaning roller 30 wipes the wetted surface to be cleaned by rotating. Therefore, the surface humidity of the first cleaning roller 20 is higher than that of the second cleaning roller 30. Therefore, in the present application, such a difference can be achieved through the following three embodiments or a combination of at least two of the three embodiments.

[0107] In one embodiment of the present application, the first scraping member 40 has a first scraping contact portion 42, and the second scraping member 50 has a second scraping contact portion 52. The first scraping contact portion 42 has an interference fit with the first cleaning roller 20, and the second scraping contact portion 52 has an interference fit with the second cleaning roller 30. The interference fit between the first scraping contact portion 42 and the first cleaning roller 20 is X1, and the interference fit between the second scraping contact portion 52 and the second cleaning roller 30 is X2, where X1<X2.

[0108] The first scraping contact portion 42 refers to the portion of the first scraping member 40 that directly contacts the first cleaning roller 20 to scrape dirt from the first cleaning roller 20, and the second scraping contact portion 52 refers to the portion of the second scraping member 50 that directly contacts the second cleaning roller 30 to scrape dirt from the second cleaning roller 30. The first scraping contact portion 42 and the first cleaning roller 20 are interference-fitted, resulting in an interference fit between the first scraping contact portion 42 and the first cleaning roller 20, and the second scraping contact portion 52 and the second cleaning roller 30 are interference-fitted, resulting in an interference fit between the second scraping contact portion 52 and the second cleaning roller 30.

[0109] When X1 < X2, that is, the second scraping contact portion 52 is pressed more tightly against the corresponding cleaning roller than the first scraping contact portion 42. This allows more of the dirty water and other substances on the second cleaning roller 30 to be scraped away, while the first cleaning roller 20 retains a relatively larger amount of water. This allows the first cleaning roller 20 to wet the surface to be cleaned by rotation, while the second cleaning roller 30 wipes the wetted surface to be cleaned by rotation, further enhancing the ability to remove stains from the surface to be cleaned. Preferably, 0.2 mm ≤ X2 - X1 ≤ 1 mm. Research has found that within this range, the cleaning capabilities of the two cleaning rollers can be further enhanced, improving the cleaning effect.

[0110] Specifically in the embodiment of the present application, the axis of the first cleaning roller 20 and the axis of the second cleaning roller 30 are symmetrically arranged relative to the center plane. The first scraping member 40 has a first scraping arm 43 extending from the center plane toward the first cleaning roller 20. The first scraping arm 43 has a first scraping contact portion 42. The second scraping member 50 further has a second scraping arm 53 extending from the center plane toward the second cleaning roller 30. The second scraping arm 53 has a second scraping contact portion 52. The length of the first scraping arm 43 is less than the length of the second scraping arm 53.

[0111] In this way, since the length of the first scraping arm 43 is smaller than the length of the second scraping arm 53, the second scraping contact portion 52 of the second scraping arm 53 is closer to the second cleaning roller 30, that is, the radial distance between the second scraping contact portion 52 and the center axis of the second cleaning roller 30 is smaller than the radial distance between the first scraping contact portion 42 and the center axis of the first cleaning roller 20. This method can more easily achieve interference fit and improve the reliability of the interference fit.

[0112] In another embodiment of the present application, the cleaning mechanism 100 further includes a waterway plate, which is disposed on the mounting base 10 and is used to guide water to the first cleaning roller 20 and the second cleaning roller 30. The average amount of water provided per unit time by the waterway plate to the first cleaning roller 20 is greater than the average amount of water provided per unit time by the waterway plate to the second cleaning roller 30.

[0113] By providing a water channel plate, water can be directed to flow toward the first cleaning roller 20 and the second cleaning roller 30, thereby achieving wetting of the first cleaning roller 20 and the second cleaning roller 30. Specifically, a first water outlet and a second water outlet are provided on the water channel plate. The first water outlet discharges water toward the first cleaning roller 20, and the second water outlet discharges water toward the second cleaning roller 30. The first water outlet and the second water outlet can be spray heads or spray ports, etc.

[0114] The cleaning mechanism 100 may further include a clean water tank and a water pump, and the clean water tank pumps clean water onto the waterway plate through the power increased by the water pump.

[0115] When the average amount of water provided by the waterway plate to the first cleaning roller 20 per unit time is greater than the average amount of water provided by the waterway plate to the second cleaning roller 30 per unit time, the first cleaning roller 20 will obtain more water. Therefore, the surface humidity of the first cleaning roller 20 is higher than the surface humidity of the second cleaning roller 30. The second cleaning roller 30 can absorb water from the external surface to be cleaned, so the first cleaning roller 20 can wet the surface to be cleaned by rotation, and the second cleaning roller 30 can wipe the wetted surface to be cleaned by rotation, thereby further improving the stain removal ability of the surface to be cleaned.

[0116] Preferably, the ratio of the average amount of water provided per unit time by the waterway plate to the first cleaning roller 20 to the average amount of water provided per unit time by the waterway plate to the second cleaning roller 30 is in the range of 1.5:1 to 3:1. Research has found that within this range, the cleaning capabilities of the two cleaning rollers can be further enhanced, improving the cleaning effect.

[0117] In yet another embodiment of the present application, the water absorption rate of the first cleaning roller 20 is lower than the water absorption rate of the second cleaning roller 30 .

[0118] Water absorption rate refers to the water absorption rate of the material. When the water absorption rate of the material used in the first cleaning roller 20 is less than the water absorption rate of the material used in the second cleaning roller 30, the first cleaning roller 20 can store more water than the second cleaning roller 30, so as to achieve the effect of wetting the surface to be cleaned by rotation, while the second cleaning roller 30 has a large water absorption rate and can be drier, so as to achieve the effect of wiping the wetted surface to be cleaned by rotation.

[0119] In some embodiments, the elastic force exerted by the first elastic member 60 on the first cleaning roller 20 is equal to the elastic force exerted by the second elastic member 70 on the second cleaning roller 30 .

[0120] When the elastic forces of the first elastic member 60 and the second elastic member 70 are equal, the above three embodiments can realize the difference in the functions of the first cleaning roller 20 and the second cleaning roller 30 , thereby simplifying the arrangement of the first elastic member 60 and the second elastic member 70 .

[0121] In other embodiments, along the cleaning direction X, the first cleaning roller 20 is located in front of the second cleaning roller 30 , and the elastic force exerted by the first elastic member 60 on the first cleaning roller 20 is smaller than the elastic force exerted by the second elastic member 70 on the second cleaning roller 30 .

[0122] When the elastic force applied by the first elastic member 60 on the first cleaning roller 20 is less than the elastic force applied by the second elastic member 70 on the second cleaning roller 30, the second elastic member 70 is closer to the second cleaning roller 30, and therefore, more sewage on the second cleaning roller 30 can be scraped off, and the second cleaning roller 30 has lower humidity, so the second cleaning roller 30 can wipe the wetted surface to be cleaned by rotation, and the force applied by the second elastic member 70 on the first cleaning roller 20 is smaller, so more water on the first cleaning roller 20 can be retained, and the first cleaning roller 20 has higher humidity, so the first cleaning roller 20 can wet the surface to be cleaned by rotation.

[0123] In the embodiment of the present application, the first scraping member 40 has a first scraping contact surface 421 . The first scraping contact surface 421 contacts the first cleaning roller 20 and is tangent to the outer surface of the first cleaning roller 20 .

[0124] By providing the first scraping contact surface 421 and making it tangential to the outer surface of the first cleaning roller 20, the first scraping contact surface 421 can always maintain contact with the first cleaning roller 20 under the rotation of the first cleaning roller 20. This not only increases the contact area but also makes the contact more reliable, thereby improving the scraping effect. In addition, because the first scraping contact surface 421 is in contact with the first cleaning roller 20, the contact and sealing between the first scraping contact surface 421 and the first cleaning roller 20 are improved during the scraping process, making it difficult for scraped dirty water to leak from the matching gap between the first scraping contact surface 421 and the first cleaning roller 20 to the surface to be cleaned, thereby improving the cleaning effect.

[0125] Preferably, the width of the first scraping contact surface 421 is in the range of 1 mm to 5 mm.

[0126] The width of the first scraping contact surface 421 referred to herein refers to the dimension in the tangential direction between the first scraping contact surface 421 and the first cleaning roller 20. Research has found that when the width of the first scraping contact surface 421 ranges from 1 mm to 5 mm, sufficient contact area is provided between the first scraping contact surface 421 and the first cleaning roller 20 to ensure effective scraping without creating excessive resistance that would affect the normal rotation of the first cleaning roller 20.

[0127] In some other embodiments, the second scraping member 50 has a second scraping contact surface 521 . The second scraping contact surface 521 contacts the second cleaning roller 30 and is tangent to the outer surface of the second cleaning roller 30 .

[0128] By providing the second scraping contact surface 521 and making it tangential to the outer surface of the second cleaning roller 30, the second scraping contact surface 521 can always maintain contact with the second cleaning roller 30 under the rotation of the second cleaning roller 30. This not only increases the contact area but also makes the contact more reliable, thereby improving the scraping effect. In addition, because the second scraping contact surface 521 is in contact with the second cleaning roller 30, the contact and sealing between the second scraping contact surface 521 and the second cleaning roller 30 are improved during the scraping process, making it difficult for scraped dirty water to leak from the clearance between the second scraping contact surface 521 and the second cleaning roller 30 to the surface to be cleaned, thereby improving the cleaning effect.

[0129] Preferably, the width of the second scraping contact surface 521 is in the range of 1 mm to 5 mm.

[0130] The width of the second scraping contact surface 521 referred to herein refers to the dimension in the tangential direction between the second scraping contact surface 521 and the second cleaning roller 30. Research has found that when the width of the second scraping contact surface 521 ranges from 1 mm to 5 mm, sufficient contact area is achieved between the two surfaces to ensure effective scraping without creating excessive resistance that would affect the normal rotation of the second cleaning roller 30.

[0131] In other embodiments, the first scraping contact surface 421 contacts the first cleaning roller 20 and is tangent to the outer surface of the first cleaning roller 20 ; the second scraping contact surface 521 contacts the second cleaning roller 30 and is tangent to the outer surface of the second cleaning roller 30 .

[0132] In some embodiments, the first scraping member 40 further has a first transition slope 44, which is adjacent to the first scraping contact surface 421 and is located on the downstream side of the first scraping contact surface 421 along the forward and reverse rotation of the first cleaning roller 20, and the first transition slope 44 is set at an angle to the first scraping contact surface 421.

[0133] When the first cleaning roller 20 is reversed, since the first transition slope 44 is located on the downstream side of the first scraping contact surface 421 along the forward rotation direction of the first cleaning roller 20, the first transition slope 44 can guide the first scraping contact surface 421 to squeeze the hair on the surface of the first cleaning roller 20, reducing the squeezing resistance. In addition, the reverse rotation of the first cleaning roller 20 can scrape off the dirt inside the first cleaning roller 20 and make the hair flattened by the forward rotation more fluffy, which is more conducive to drying. Specifically, the forward rotation direction of the first cleaning roller 20 is clockwise, and the reverse rotation direction of the first cleaning roller 20 is counterclockwise.

[0134] In some embodiments, the first scraping member 40 further has a second transition slope 45, which is adjacent to the first scraping contact surface 421 and is located on the upstream side of the first scraping contact surface 421 along the forward and reverse rotation of the first cleaning roller 20, and the second transition slope 45 is set at an angle to the first scraping contact surface 421.

[0135] When the first cleaning roller 20 rotates in the forward direction, since the second transition slope 45 is located upstream of the first scraping contact surface 421 along the forward direction of the first cleaning roller 20, the second transition slope 45 can guide the first scraping contact surface 421 to squeeze the hair on the surface of the first cleaning roller 20, reducing the squeezing resistance and making scraping smooth.

[0136] Preferably, a first angle α1 is defined between the first transition slope 44 and the first scraping contact surface 421, with the first angle α1 ranging from 20 to 60 degrees. A second angle is defined between the second transition slope 45 and the first scraping contact surface 421, with the second angle ranging from 20 to 60 degrees. Research has found that within this range, the first scraping member 40 can more smoothly scrape the surface of the first cleaning roller 20, achieving a better scraping effect.

[0137] In some embodiments, the second scraping member 50 further has a third transition slope 54, which is adjacent to the second scraping contact surface 521 and is located on the downstream side of the second scraping contact surface 521 along the forward and reverse rotation directions of the second cleaning roller 30, and the third transition slope 54 is set at an angle to the second scraping contact surface 521.

[0138] When the second cleaning roller 30 is reversed and the third transition slope 54 is located downstream of the second scraping contact surface 521 along the forward rotation direction of the second cleaning roller 30, the third transition slope 54 can guide the second scraping contact surface 521 to squeeze the hair on the surface of the second cleaning roller 30, reducing the squeezing resistance. The reverse rotation of the second cleaning roller 30 can scrape off the dirt inside the second cleaning roller 30 and make the hair flattened by the forward rotation more fluffy, which is more conducive to drying. Specifically, the forward rotation direction of the second cleaning roller 30 is counterclockwise, and the reverse rotation direction of the second cleaning roller 30 is clockwise.

[0139] In some embodiments, the second scraping member 50 further has a fourth transition slope 55, which is adjacent to the first scraping contact surface 421 and is located on the upstream side of the first scraping contact surface 421 along the forward and reverse rotation directions of the first cleaning roller 20, and is set at an angle to the first scraping contact surface 421.

[0140] When the second cleaning roller 30 rotates forward, since the fourth transition slope 55 is located upstream of the second scraping contact surface 521 along the forward rotation direction of the second cleaning roller 30, the fourth transition slope 55 can guide the second scraping contact surface 521 to squeeze the hair on the surface of the second cleaning roller 30, reducing the squeezing resistance.

[0141] Preferably, a third angle α3 is formed between the second transition slope 45 and the second scraping contact surface 521, and the range of the third angle α3 is 20 degrees to 60 degrees. Studies have found that within this range, the second scraping member 50 can scrape the surface of the second cleaning roller 30 more smoothly, achieving a better scraping effect.

[0142] It should be understood here that the forward rotation direction of the first cleaning roller 20 refers to the reverse rotation direction of the first cleaning roller 20 when normally cleaning the surface to be cleaned, and the reverse rotation direction of the first cleaning roller 20 is opposite to the forward rotation direction. When the first cleaning roller 20 is in the reverse direction, the first cleaning roller 20 may not clean the surface to be cleaned. Similarly, the forward rotation direction of the second cleaning roller 30 refers to the reverse rotation direction of the second cleaning roller 30 when normally cleaning the surface to be cleaned, and the reverse rotation direction of the second cleaning roller 30 is opposite to the forward rotation direction. When the second cleaning roller 30 is in the reverse direction, the second cleaning roller 30 may not clean the surface to be cleaned. The forward and reverse rotation directions of the first cleaning roller 20 and the second cleaning roller 30 may be the same or opposite.

[0143] In the embodiment of the present application, the first scraping member 40 and the second scraping member 50 are both arranged between the first cleaning roller 20 and the second cleaning roller 30, and the first cleaning roller 20 and the second cleaning roller 30 rotate in opposite directions. Figure 3It can be seen that the first cleaning roller 20 rotates clockwise, while the second cleaning roller 30 rotates counterclockwise. When both the first scraper 40 and the second scraper 50 are disposed between the first cleaning roller 20 and the second cleaning roller 30, the scraping contact surfaces of the first scraper 40 and the second scraper 50, which contact the first cleaning roller 20 and the second cleaning roller 30, respectively, are disposed between the first cleaning roller 20 and the second cleaning roller 30. Therefore, by rotating the first cleaning roller 20 clockwise and the second cleaning roller 30 counterclockwise, wastewater, excess water, or other impurities can be scraped off from beneath the first scraper 40 and the second scraper 50. At this point, the scraped wastewater, excess water, or other impurities can be directly guided from the first scraper 40 to the waste receiving member below under the action of gravity, thereby reducing the risk of the scraped wastewater, excess water, or other impurities leaking from the first scraper 40 to the cleaned surface.

[0144] In an embodiment of the present application, the cleaning mechanism 100 further includes a first anti-slip limiter connected to the mounting seat 10 , and the first scraping member 40 is limited between the first anti-slip limiter and the mounting seat 10 .

[0145] Since the first scraping member 40 is movable relative to the mounting seat 10, limiting the first scraping member 40 between the first anti-slip limiter and the mounting seat 10 can limit the range of movement of the first scraping member 40 relative to the mounting seat 10, improve scraping reliability, and reduce the risk of damage to the first scraping member 40.

[0146] Specifically, when the first scraper 40 is movably disposed on the mounting base 10 in the vertical direction, the first scraper 40 can move vertically relative to the mounting base 10 within a range of 0.5 mm to 5 mm. This range of movement can be achieved by the first anti-slip stopper and the mounting base 10.

[0147] Preferably, the first anti-drop limiter is a screw, which cooperates with the screw hole of the mounting seat 10 to achieve fixation.

[0148] Similarly, the cleaning mechanism 100 further includes a second anti-slip limiter connected to the mounting base 10, and the second scraping member 50 is limited between the first anti-slip limiter and the mounting base 10. The specific structure and arrangement of the second anti-slip limiter are similar to those of the first anti-slip limiter, and will not be repeated here.

[0149] Based on the same inventive concept, the present application further provides a cleaning device, comprising a cleaning body and the cleaning mechanism 100 in any of the above embodiments. The cleaning mechanism 100 is mounted on the cleaning body.

[0150] The cleaning body may include a housing and a controller, and may also include structures such as a clean water tank, a sewage tank, and a water pump.

[0151] Specifically, the cleaning device can be a cleaning robot, or a handheld floor scrubber, a handheld floor mop, etc.

[0152] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0153] The above-described embodiments merely represent several implementation methods of the present application. 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 a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
