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

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

[0028] In one embodiment, the ratio range of the average amount of water provided by the water channel plate to the first cleaning roller per unit time to the average amount of water provided by the water channel plate to the second cleaning roller per unit time is: 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; the water absorption rate of the first cleaning roller is less than the water absorption rate of the second cleaning roller.

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

[0031] And / or the second scraping member has a second scraping contact surface, the second scraping contact surface is in contact with the second cleaning roller and is tangent to the outer surface of the second cleaning roller.

[0032] In one embodiment, the width range of the first scraping contact surface is 1 mm to 5 mm;

[0033] And / or the width range of the second scraping contact surface is 1 mm to 5 mm.

[0034] In one embodiment, the first scraping member further has a first transition inclined surface, which is adjacent to the first scraping contact surface and is located on the downstream side of the first scraping contact surface along the forward rotation direction of the first cleaning roller. The first transition inclined surface is arranged at an angle with the first scraping contact surface;

[0035] And / or the second scraping member further has a third transition inclined surface, which is adjacent to the second scraping contact surface and is located on the downstream side of the second scraping contact surface along the forward rotation direction of the second cleaning roller. The third transition inclined surface is arranged at an angle with the second scraping contact surface.

[0040] On the other hand, the present application also provides a cleaning device, which includes a cleaning main body and the cleaning mechanism in any of the above embodiments, and the cleaning mechanism is installed on the cleaning main body.

[0041] For the above - mentioned cleaning mechanism and cleaning device, when the first cleaning roller and the second cleaning roller are worn after long - term use, the elastic force of the first elastic member can be used to keep the first scraping member always in contact with the first cleaning roller, and the elastic force of the second elastic member can be used to keep the second scraping member always in contact with the second cleaning roller. Therefore, the first cleaning roller and the second cleaning roller can always be scraped to remove sewage, excess water or other impurities by the first scraping member and the second scraping member respectively, reducing the sewage residue amount on the first cleaning roller and the second cleaning roller, and further reducing the water stains on the surface to be cleaned, thus improving the cleaning effect.

[0042] In addition, it should be noted that during actual use, when the wear rates of the first cleaning roller and the second cleaning roller are different, it is possible that the second cleaning roller wears faster and its diameter becomes smaller than that of the first cleaning roller. However, since the second dirt scraping member and the first dirt scraping member are separately and independently arranged, the movement of the second dirt scraping member is not affected by the first dirt scraping member, enabling the second dirt scraping member to maintain contact with the second cleaning roller and ensuring that the second cleaning roller can reach an ideal wet state, reducing the generation of water stains.

[0043] Moreover, when X1 < X2, that is to say, the second dirt scraping contact portion presses more tightly against the corresponding cleaning roller compared to the first dirt scraping contact portion, enabling more sewage on the second cleaning roller to be scraped off, while the first cleaning roller retains relatively more water. Therefore, it is possible to achieve that the first cleaning roller wets the surface to be cleaned by rotation, while the second cleaning roller wipes the wetted surface to be cleaned by rotation, further enhancing the stain removal ability of the surface to be cleaned.

Detailed implementation manners

[0053] To make the above objects, features, and advantages of the present application more apparent and understandable, the following will describe the detailed implementation manners of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0054] In the description of the present application, it should be understood that if terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present application.

[0055] In addition, if terms such as "first" and "second" appear, these terms are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0056] In this application, unless otherwise clearly specified and defined, if terms such as "installed", "connected", "linked", "fixed", etc. appear, these terms shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0057] In this application, unless otherwise clearly specified and defined, if there is a description such as a first feature being "on" or "under" a second feature, its meaning can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or simply means that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or simply means that the first feature has a lower horizontal height than the second feature.

[0058] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0059] As described in the background art, the robots in the related art adopt a self-cleaning solution with a roller mop cooperating with a squeegee. In actual application, after the robot starts the cleaning function, it can continuously wet the roller mop through the water tank, and the squeegee contacts the roller mop to squeeze out the sewage on the roller mop, which is then collected by the sewage chamber, so as to achieve the purpose of cleaning the ground or other surfaces to be cleaned.

[0060] However, after the roller mop is used for a long time, it will be worn, resulting in the loss of contact between the squeegee and the roller mop, causing the squeegee to be unable to squeeze out the sewage on the roller mop, increasing the amount of sewage residue on the roller mop, and further increasing the water stains on the surface to be cleaned and deteriorating the cleaning effect.

[0061] To solve the problem that the water stains on the surface to be cleaned increase and the cleaning effect deteriorates after the roller mop is used for a long time, in the related art, a wear-resistant roller mop or a solution of regularly asking the user to replace the scraper is adopted, but both require manual intervention and cannot achieve automatic adjustment of the robot.

[0062] Therefore, this application designs a cleaning mechanism and a cleaning device, which can automatically adjust the scraper so that the scraper can keep in contact with the roller mop, thereby solving the problem that the water stains on the surface to be cleaned increase and the cleaning effect deteriorates after the roller mop is used for a long time.

[0063] Refer to Figures 1 to 5 As shown in, a cleaning mechanism 100 provided in an embodiment of this application includes a mounting base 10, a first cleaning roller 20, a second cleaning roller 30, a first scraping member 40 and a second scraping member 50. The cleaning mechanism 100 of the embodiment of this application can be a part of the cleaning device and is detachably connected to the main body part of the cleaning device. For example, the cleaning mechanism 100 can be used as the cleaning head of a hand-held floor washer or a hand-held mop. In some other embodiments, the cleaning mechanism 100 can also be a separate whole to achieve the automatic cleaning function. For example, the cleaning mechanism 100 is a cleaning robot, and also includes 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 about their own axes and are spaced apart from each other along the cleaning direction X.

[0065] Among them, the mounting base 10 refers to a seat structure capable of mounting components. The mounting base 10 can be block-shaped, flat-plate-shaped, or a bracket structure, etc. Specifically, in the embodiment of this application, the mounting base 10 has a connecting portion 11 and a matching portion 12 connected to both sides of the connecting portion 11. Each matching 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 respectively mounted on the inner sides of the two matching portions 12. In this way, a matching gap can be formed between the first cleaning roller 20 and the matching portion 12 and between the second cleaning roller 30 and the matching portion 12. The matching portion 12 can not only play a role in protecting the first cleaning roller 20 and the second cleaning roller 30, but also block the water thrown outwards due to rotation during the cleaning process by the first cleaning roller 20 and the second cleaning roller 30. In addition, when the cleaning mechanism 100 also has a dust suction function, this matching gap can also enable the first cleaning roller 20 and the second cleaning roller 30 to have sufficient suction for sucking dust, sewage, etc. between them and the mounting base 10.

[0066] The cleaning direction X is the traveling direction of the cleaning mechanism 100, and specifically can refer to the direction in which the cleaning mechanism 100 cleans forward.

[0067] Both the first cleaning roller 20 and the second cleaning roller 30 can rotate about their own axes under the drive of the drive mechanism. In the embodiment of the present application, the arrangement of the two cleaning rollers, the first cleaning roller 20 and the second cleaning roller 30, is adopted, which can not only improve the cleaning efficiency and 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 ability to remove stains from the surface to be cleaned can be further improved.

[0068] Both the first dirt scraping member 40 and the second dirt scraping member 50 are provided on the mounting seat 10 and can be in contact with the first cleaning roller 20 and the second cleaning roller 30. The first dirt scraping member 40 and the second dirt scraping member 50 refer to members that can scrape off dirt on components. In the embodiment of the present application, the first dirt scraping member 40 can scrape off sewage, excess water or other impurities on the first cleaning roller 20, and the second dirt scraping member 50 can scrape off sewage, excess water or other impurities on the second cleaning roller 30. The dirt scraped off by the first dirt scraping member 40 and the second dirt scraping member 50 will be recycled by the recycling mechanism on the cleaning mechanism 100. The recycling mechanism can include a dirt receiving member, a dirt suction pipe, a sewage tank and a vacuum pump, etc. The sewage tank generates negative pressure through the vacuum pump, and the sewage tank is connected to the dirt receiving member through the dirt suction pipe. In this way, the sewage in the dirt receiving member can be sucked through the dirt suction pipe into the sewage tank for collection by means of vacuum suction. The sewage in the sewage tank can wait for the user to clean and discharge it or be automatically cleaned and discharged at the base station.

[0069] It should be noted here that in order to achieve a better dirt scraping effect, there is usually a certain interference amount between the first dirt scraping member 40 and the first cleaning roller 20, so that the first dirt scraping member 40 can abut against the surface of the first cleaning roller 20 and can smoothly scrape off the sewage, excess water or other impurities on the first cleaning roller 20. Similarly, there is a certain interference amount between the second dirt scraping member 50 and the second cleaning roller 30, so that the second dirt scraping member 50 can abut against the surface of the second cleaning roller 30 and can smoothly scrape off the sewage, excess water or other impurities on the second cleaning roller 30.

[0070] In an embodiment of the present application, the first scraping member 40 and the second scraping member 50 are both movably disposed on the mounting base 10. That is to say, the first scraping member 40 and the second scraping member 50 are not fixed on the mounting base 10, but can move relative to the first cleaning roller 20 and the second cleaning roller 30 on the mounting base 10. Therefore, the interference amount between the first scraping member 40 and the first cleaning roller 20 and between the second scraping member 50 and the second cleaning roller 30 can be adjusted according to the actual situation. Therefore, when the first cleaning roller 20 and the second cleaning roller 30 are worn after long-term use, the first scraping member 40 and the second scraping member 50 can be adjusted so that the first scraping member 40 and the second scraping member 50 are respectively in contact with the first cleaning roller 20 and the second cleaning roller 30, reducing the amount of sewage remaining on the first cleaning roller 20 and the second cleaning roller 30, and further reducing the water stains on the surface to be cleaned, thereby improving the cleaning effect.

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

[0072] When the first scraping member 40 rotates relative to the mounting base 10 about the first axis, it can approach or move away from the first cleaning roller 20 in the rotation direction, thereby adjusting the interference amount between the first cleaning roller 20 and the first scraping member 40 at the same time. This rotation method is simple, and, compared with the translation method, the rotation method occupies less space.

[0073] Similarly, the second scraping member 50 can rotate relative to the mounting base 10 about the second axis.

[0074] When the second scraping member 50 rotates relative to the mounting base 10 about the second axis, it can approach or move away from the second cleaning roller 30 in the rotation direction, thereby adjusting the interference amount between the second cleaning roller 30 and the second scraping member 50 at the same time. This rotation method is simple, and, compared with the translation method, the rotation method occupies less space.

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

[0076] In order to automatically adjust the interference amount between the first scraping member 40 and the first cleaning roller 20 and automatically adjust the interference amount between the second scraping member 50 and the second cleaning roller 30, in the embodiments 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 seat 10 and the first scraping member 40 and is used 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 seat 10 and the second scraping member 50 and is used 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 refer to members that can undergo elastic deformation under the action of an external force and have an elastic restoring force that can automatically restore the elastic deformation.

[0078] Therefore, when the first cleaning roller 20 and the second cleaning roller 30 are worn 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 all the time, 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 all the time. Therefore, the first cleaning roller 20 and the second cleaning roller 30 can always be scraped of sewage, excess water or other impurities by the action of the first scraping member 40 and the second scraping member 50 respectively, reducing the amount of sewage residue on the first cleaning roller 20 and the second cleaning roller 30, and further reducing the water stains on the surface to be cleaned, thus improving the cleaning effect.

[0079] In addition, it should also be pointed out that during actual use, when the wear rates of the first cleaning roller 20 and the second cleaning roller 30 are different, there may be a situation where the second cleaning roller 30 wears faster and its diameter is smaller than that of the first cleaning roller 20. However, since the second scraping member 50 and the first scraping member 40 are separately and independently arranged, 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 keep in 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] In the parallel arrangement, the distance from any position of the first rotating shaft to the surface of the first cleaning roller 20 in the direction perpendicular to the first rotating shaft will be kept consistent, so that the force between the first scraping member 40 and the first cleaning roller 20 is balanced, improving the reliability of scraping.

[0082] Similarly, the second axis can 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 also be kept consistent, so that the force between the second scraping member 50 and the second cleaning roller 30 is balanced, improving the reliability of scraping.

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

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

[0086] Specifically, a rotating shaft 13 having a first axis and a second axis is fixed on the mounting seat 10. One end of the first scraping member 40 has a first shaft hole 41, and one end of the second scraping member 50 has a second shaft hole 51. 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 on the mounting seat 10, when the rotating shaft 13 passes through the first shaft hole 41 and the second shaft hole 51 and cooperates with the first shaft hole 41 and the second shaft hole 51, the first scraping member 40 can rotate around the rotating shaft 13. At the same time, the second scraping member 50 can also rotate around the rotating shaft 13. Therefore, the rotation of both the first scraping member 40 and the second scraping member 50 is realized simultaneously. This structure is simple and the rotational installation is reliable.

[0088] In some embodiments, the number of the first shaft holes 41 and the second shaft holes 51 can include multiple ones. The multiple first shaft holes 41 and second shaft holes 51 are arranged at intervals along the extending 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. By arranging the first shaft holes 41 and the second shaft holes 51 in a staggered manner along the extending direction of the rotating shaft 13, the force uniformity of the first scraping member 40 and the second scraping member 50 at the position of the rotating shaft 13 can be improved.

[0089] In some embodiments, the rotating shaft 13 can be an integral body or can be divided into multiple segments to cooperate with multiple first shaft holes 41 and second shaft holes 51. Preferably, the rotating shaft 13 is divided into two segments, specifically a first rotating shaft and a second rotating shaft. The first rotating shaft cooperates with at least two first shaft holes 41 and at least two second shaft holes 51, and the second rotating shaft cooperates with at least two first shaft holes 41 and at least two second shaft holes 51. Since the rotating shaft 13 is relatively long, it is divided into multiple segments. On the one hand, the structural strength of the rotating shaft 13 can be improved, and on the other hand, the assembly difficulty can be reduced when cooperating with multiple first shaft holes 41 and second shaft holes 51.

[0090] It should be noted that in other embodiments, the first axis may also not coincide with the second axis, but maintain a certain 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] Combined with Figure 6 and Figure 7 , in some embodiments, during the rotation of the first scraping member 40, it includes a first limit position and a second limit position. When the first scraping member 40 is in the first limit position, the first scraping member 40 abuts against the mounting seat 10. When the first scraping member 40 is in the second limit position, the first scraping member 40 abuts against the second scraping member 50.

[0092] When the first rotating shaft of the first scraping member 40 coincides with the second rotating shaft of the second scraping member 50, the positions between the first scraping member 40 and the second scraping member 50 are very close. Therefore, by using the abutting relationship between the first scraping member 40 and the second scraping member 50 to achieve limiting, the limiting can be more conveniently realized. And the mounting seat 10 is a fixed structure. Therefore, it is also very reliable to limit the position of the first scraping member 40 through the mounting seat 10.

[0093] Specifically, the first limit position herein refers to the uppermost limit position of the first scraping member 40 in the vertical direction, and the second limit position is the lowermost limit position of the second scraping member 50 in the vertical direction.

[0094] Similarly, during the rotation of the second scraping member 50, it includes a third limit position and a fourth limit position. When the second scraping member 50 is in the third limit position, the second scraping member 50 abuts against the mounting seat 10. When the second scraping member 50 is in the second limit position, the first scraping member 40 abuts against the second scraping member 50.

[0095] When the first rotating shaft of the first scraping member 40 coincides with the second rotating shaft of the second scraping member 50, the positions between the first scraping member 40 and the second scraping member 50 are very close. Therefore, by using the abutting relationship between the first scraping member 40 and the second scraping member 50 to achieve limiting, the limiting can be more conveniently realized. And the mounting seat 10 is a fixed structure. Therefore, it is also very reliable to limit the position of the second scraping member 50 through the mounting seat 10.

[0096] In some embodiments, the number of the first elastic members 60 may include at least two, such as three, four or six, etc. All the first elastic members 60 are spaced apart from each other in a first direction, wherein the first direction is parallel to the axial direction of the first cleaning roller 20. Similarly, the number of the second elastic members 70 may include at least two, such as three, four or six, etc. All the second elastic members 70 are spaced apart from each other in the first direction, wherein the first direction is parallel to the axial direction of the second cleaning roller 30.

[0097] By arranging all the first elastic members 60 at intervals of each other in the first direction, the elastic force provided by the first elastic members 60 to the first scraping member 40 can be made uniform, and the first scraping member 40 is in balanced force, so that the contact between the first scraping member 40 and the first cleaning roller 20 is comprehensive and stable, improving the scraping effect. By arranging all the second elastic members 70 at intervals of each other in the first direction, the elastic force provided by the second elastic members 70 to the second scraping member 50 can be made uniform, and the second scraping member 50 is in balanced force, so that the contact between the second scraping member 50 and the second cleaning roller 30 is comprehensive and stable, improving the scraping effect.

[0098] Further, the first scraping member 40 has a first central axis parallel to the first direction, and all the first elastic members 60 are arranged on the first central axis. When all the first elastic members 60 are arranged on the first central axis of the scraping member 40, the forces on both sides of the first scraping member 40 along the first central axis can be made uniform, so that the first scraping member 40 can maintain a stable contact with the first cleaning roller 20.

[0099] In other embodiments, it is also possible to arrange all the first elastic members 60 to be symmetrically distributed relative to the first central axis. In this way, the forces on both sides of the first scraping member 40 along the first central axis are uniform, so that the first scraping member 40 can maintain a stable contact with 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 forces on both sides of the second scraping member 50 along the second central axis can be made uniform, so that the second scraping member 50 can maintain a stable contact with the second cleaning roller 30.

[0101] In other embodiments, it is also possible to arrange all the second elastic members 70 to be symmetrically distributed relative to the second central axis. In this way, the forces on both sides of the second scraping member 50 along the second central axis are uniform, so that the second scraping member 50 can maintain a stable contact with the second cleaning roller 30.

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

[0103] The elastic force range applied by all the first elastic members 60 on the first scraping member 40 is 5 N to 25 N, which means that when all the first elastic members 60 are compressed to the shortest length, at this time the first scraping member 40 is at the topmost position, and the elastic force applied by all the first elastic members 60 on the first scraping member 40 does not exceed 25 N. When all the first elastic members 60 are compressed to the longest length, at this time the first scraping member 40 is at the bottommost position, and the elastic force applied by all the first elastic members 60 on the first scraping member 40 is not less than 5 N. Within this range, the first scraping member 40 can always maintain a certain interference amount with the first cleaning roller 20 during the initial stage of use and the wear process in the later stage of the first cleaning roller 20, improving the scraping effect and thus the cleaning effect.

[0104] Similarly, the elastic force range applied by all the second elastic members 70 on the second scraping member 50 is 5 N to 25 N. Within this range, the second scraping member 50 can always maintain a certain interference amount with the first cleaning roller 20 during the initial stage of use and the wear process in the later stage of the first cleaning roller 20, 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 also be replaced by elastic structures, such as rubber, etc. In addition, when the first scraping member 40 and the second scraping member 50 can 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 functions of the two cleaning rollers are different. 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. 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 implementation manners or a combination of at least two of the three implementation manners.

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

[0108] The first scraping contact part 42 refers to the part on the first scraping member 40 that directly contacts the first cleaning roller 20 to scrape the first cleaning roller 20. The second scraping contact part 52 refers to the part on the second scraping member 50 that directly contacts the second cleaning roller 30 to scrape the second cleaning roller 30. An interference fit is provided between the first scraping contact part 42 and the first cleaning roller 20, so that an interference amount is generated between the first scraping contact part 42 and the first cleaning roller 20. An interference fit is provided between the second scraping contact part 52 and the second cleaning roller 30, so that an interference amount is generated between the second scraping contact part 52 and the second cleaning roller 30.

[0109] When X1 < X2, that is to say, the second scraping contact part 52 presses more tightly on the corresponding cleaning roller than the first scraping contact part 42. In this way, more sewage and the like on the second cleaning roller 30 can be scraped off, while the first cleaning roller 20 relatively retains more water. Therefore, it can be realized that the first cleaning roller 20 wets the surface to be cleaned by rotation, and the second cleaning roller 30 wipes the wetted surface to be cleaned by rotation, further improving the stain removal ability of the surface to be cleaned. Preferably, 0.2 mm ≤ X2 - X1 ≤ 1 mm. Through research, it is found that within this range, the corresponding cleaning capabilities of the two cleaning rollers can be further improved, and the cleaning effect can be enhanced.

[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 central plane. The first scraping member 40 has a first scraping arm 43 extending from the central plane to the first cleaning roller 20, and the first scraping arm 43 has a first scraping contact part 42. The second scraping member 50 also has a second scraping arm 53 extending from the central plane to the second cleaning roller 30, and the second scraping arm 53 has a second scraping contact part 52. Among them, 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 less than the length of the second scraping arm 53, the second scraping contact part 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 part 52 and the central axis of the second cleaning roller 30 is less than the radial distance between the first scraping contact part 42 and the central axis of the first cleaning roller 20. This method can more simply achieve an 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 water circuit board, which is arranged on the mounting base 10 and is used to guide water to the first cleaning roller 20 and the second cleaning roller 30. Among them, the average amount of water provided by the water circuit board to the first cleaning roller 20 per unit time is greater than the average amount of water provided by the water circuit board to the second cleaning roller 30 per unit time.

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

[0114] The cleaning mechanism 100 may also be provided with a clean water tank and a water pump. The clean water tank pumps clean water onto the water channel plate by the power provided by the water pump.

[0115] When the average amount of water provided by the water channel plate to the first cleaning roller 20 per unit time is greater than the average amount of water provided by the water channel plate to the second cleaning roller 30 per unit time, the first cleaning roller 20 will receive 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 the water on the surface to be cleaned outside. Therefore, 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, further improving the stain removal ability of the surface to be cleaned.

[0116] Preferably, the ratio range of the average amount of water provided by the water channel plate to the first cleaning roller 20 per unit time to the average amount of water provided by the water channel plate to the second cleaning roller 30 per unit time is 1.5:1 to 3:1. It has been found through research that within this range, the corresponding cleaning capabilities of the two cleaning rollers can be further improved, and the cleaning effect can be enhanced.

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

[0118] The water absorption rate refers to the water absorption rate of the material. When the water absorption rate of the material used for the first cleaning roller 20 is less than the water absorption rate of the material used for the second cleaning roller 30, the first cleaning roller 20 can store more water compared to the second cleaning roller 30 to achieve the effect of wetting the surface to be cleaned by rotation, while the second cleaning roller 30 has a high water absorption rate and can be drier 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 differences in the functions of the aforementioned first cleaning roller 20 and the second cleaning roller 30 can be achieved through the above three implementation manners, which simplifies the settings of the first elastic member 60 and the second elastic member 70.

[0121] In some 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 less than the elastic force exerted by the second elastic member 70 on the second cleaning roller 30.

[0122] When the elastic force exerted by the first elastic member 60 on the first cleaning roller 20 is less than the elastic force exerted 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. Therefore, more sewage on the second cleaning roller 30 can be scraped off, and the second cleaning roller 30 has a lower humidity. Thus, the function of the second cleaning roller 30 to wipe the wetted surface to be cleaned by rotation is realized. And the force exerted 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 a higher humidity. Thus, the function of the first cleaning roller 20 to wet the surface to be cleaned by rotation is realized.

[0123] In the embodiments of the present application, the first sewage scraping member 40 has a first sewage scraping contact surface 421, and the first sewage scraping contact surface 421 is in contact with the first cleaning roller 20 and is tangent to the outer surface of the first cleaning roller 20.

[0124] By setting the first sewage scraping contact surface 421 and making the first sewage scraping contact surface 421 tangent to the outer surface of the first cleaning roller 20, the contact between the first sewage scraping contact surface 421 and the first cleaning roller 20 can be always maintained 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 sewage scraping effect. In addition, since the first sewage scraping contact surface 421 is in contact with the first cleaning roller 20, during the scraping process, the contact sealing between the first sewage scraping contact surface 421 and the first cleaning roller 20 is better, so that the scraped sewage is not easily leaked from the fitting gap between the first sewage scraping contact surface 421 and the first cleaning roller 20 to the surface to be cleaned, thereby making the cleaning effect better.

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

[0126] The width of the first scraping contact surface 421 referred to herein is the dimension in the tangential direction of the first scraping contact surface 421 and the first cleaning roller 20. Through research, it is found that when the width range of the first scraping contact surface 421 is 1 mm to 5 mm, sufficient contact area can be achieved between the two to ensure the scraping effect, and too much resistance will not be brought to 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 is in contact with 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 the second scraping contact surface 521 tangent to the outer surface of the second cleaning roller 30, the contact between the second scraping contact surface 521 and the second cleaning roller 30 can be maintained under the rotation of the second cleaning roller 30. This not only increases the contact area but also makes the contact more reliable, thus improving the scraping effect. In addition, since the second scraping contact surface 521 is in contact with the second cleaning roller 30, during the scraping process, the contact sealing between the second scraping contact surface 521 and the second cleaning roller 30 is better, so that the scraped sewage is not easily leaked from the mating gap between the second scraping contact surface 521 and the second cleaning roller 30 to the surface to be cleaned, thereby making the cleaning effect better.

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

[0130] The width of the second scraping contact surface 521 referred to herein is the dimension in the tangential direction of the second scraping contact surface 521 and the second cleaning roller 30. Through research, it is found that when the width range of the second scraping contact surface 521 is 1 mm to 5 mm, sufficient contact area can be achieved between the two to ensure the scraping effect, and too much resistance will not be brought to affect the normal rotation of the second cleaning roller 30.

[0131] In other embodiments, the first scraping contact surface 421 is in contact with the first cleaning roller 20 and is tangent to the outer surface of the first cleaning roller 20; the second scraping contact surface 521 is in contact with 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, the first transition slope 44 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 directions of the first cleaning roller 20, and the first transition slope 44 and the first scraping contact surface 421 are arranged at an angle.

[0133] When the first cleaning roller 20 rotates in the reverse direction, 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 extrusion resistance. Moreover, the reverse rotation of the first cleaning roller 20 can scrape off the dirt inside the first cleaning roller 20 and also make the hair flattened during forward rotation fluffier, 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. The second transition slope 45 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 reverse forward rotation direction of the first cleaning roller 20. The second transition slope 45 and the first scraping contact surface 421 are arranged at an angle.

[0135] When the first cleaning roller 20 rotates in the forward direction, since the second transition slope 45 is located on the upstream side of the first scraping contact surface 421 along the forward rotation 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 extrusion resistance and making the scraping smooth.

[0136] Preferably, there is a first included angle α1 between the first transition slope 44 and the first scraping contact surface 421, and the range of the first included angle α1 is 20 degrees to 60 degrees. There is a second included angle between the second transition slope 45 and the first scraping contact surface 421, and the range of the second included angle is 20 degrees to 60 degrees. It has been found through research that within this range, the first scraping member 40 can scrape the surface of the first cleaning roller 20 more smoothly and the scraping effect is better.

[0137] In some embodiments, the second scraping member 50 further has a third transition slope 54. The third transition slope 54 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 reverse forward rotation direction of the second cleaning roller 30. The third transition slope 54 and the second scraping contact surface 521 are arranged at an angle.

[0138] When the second cleaning roller 30 rotates in the reverse direction and the third transition slope 54 is located on the downstream side 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 extrusion resistance. Moreover, the reverse rotation of the second cleaning roller 30 can scrape off the dirt inside the second cleaning roller 30 and also make the hair flattened during forward rotation fluffier, 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 inclined surface 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 rotation direction of the first cleaning roller 20. An angle is provided between the fourth transition inclined surface 55 and the first scraping contact surface 421.

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

[0141] Preferably, there is a third included angle α3 between the second transition inclined surface 45 and the second scraping contact surface 521, and the range of the third included angle α3 is 20 degrees to 60 degrees. It has been found through research that within this range, the second scraping member 50 can scrape the surface of the second cleaning roller 30 more smoothly and has a better scraping effect.

[0142] It should be understood here that the forward rotation direction of the first cleaning roller 20 refers to the rotation direction of the first cleaning roller 20 when it normally cleans the surface to be cleaned. 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 rotation 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 rotation direction of the second cleaning roller 30 when it normally cleans the surface to be cleaned. 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 rotation 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 embodiments of the present application, both the first scraping member 40 and the second scraping member 50 are provided between the first cleaning roller 20 and the second cleaning roller 30, and the forward and reverse rotation directions of the first cleaning roller 20 and the second cleaning roller 30 are opposite. From the attached Figure 3It can be seen that the rotation direction of the first cleaning roller 20 is clockwise, and the rotation direction of the second cleaning roller 30 is counterclockwise. When both the first scraping member 40 and the second scraping member 50 are disposed between the first cleaning roller 20 and the second cleaning roller 30, the scraping contact surfaces where the first scraping member 40 and the second scraping member 50 are respectively in contact with the first cleaning roller 20 and the second cleaning roller 30 are both disposed between the first cleaning roller 20 and the second cleaning roller 30. Therefore, by making the rotation direction of the first cleaning roller 20 clockwise and the rotation direction of the second cleaning roller 30 counterclockwise, it is possible to scrape off sewage, excess water, or other impurities below the first scraping member 40 and the second scraping member 50. At this time, the scraped sewage, excess water, or other impurities can directly flow from the first scraping member 40 to the underlying sewage receiving member under the action of gravity, reducing the risk of the scraped sewage, excess water, or other impurities leaking from the first scraping member 40 to the already cleaned surface.

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

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

[0146] Specifically, when the first scraping member 40 is movably disposed on the mounting seat 10 along the vertical direction, the moving range of the first scraping member 40 moving relative to the mounting seat 10 along the vertical direction is 0.5 mm - 5 mm. In this way, this moving range can be achieved by the limiting of the first anti - detachment limiting member and the mounting seat 10.

[0147] Preferably, the first anti - detachment limiting member is a screw, and the screw is engaged with the screw hole of the mounting seat 10 to achieve fixation.

[0148] Similarly, the cleaning mechanism 100 further includes a second anti - detachment limiting member, the second anti - detachment limiting member is connected to the mounting seat 10, and the second scraping member 50 is limited between the first anti - detachment limiting member and the mounting seat 10. The specific structure and setting of the second anti - detachment limiting member are similar to those of the first anti - detachment limiting member, and will not be elaborated here.

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

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

[0151] Specifically, the cleaning device may be a cleaning robot, or a handheld floor washer, a handheld floor mopper, etc.

[0152] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope described in this specification.

[0153] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
