Description

TECHNICAL FIELD

The present disclosure relates to the field of cleaning technology, and in particular to cleaning devices.

BACKGROUND

In family life, tedious housework takes up a lot of time and energy, and cleaning devices come into being in such a context. Some of the existing cleaning devices, such as mopping machines, generally work by rolling a roller so that a surface of the roller mops and washes a surface to be cleaned. To avoid the cleaning device from being too large and thus inconvenient for a user to operate, a volume of the existing roller is set to be small, and a surface area of the roller is limited. As a result, after the cleaning device works for a period of time, the surface of the roller quickly becomes dirty, which results in a poor cleaning effect when the cleaning roller continues to carry out the cleaning work.

SUMMARY

The present disclosure, in view of the above existing condition, aims to provide cleaning devices to improve a cleaning effect.

To this end, the present disclosure provides a cleaning device including a cleaning component and a cleaning aid member. The cleaning component includes a first annular cleaning belt, a first roller, and a second roller. The first roller is spaced apart from the second roller, the second roller is disposed above the first roller, and the first annular cleaning belt rotatably surrounds the first roller and the second roller for cleaning a surface to be cleaned. The cleaning aid member is disposed behind the cleaning component along a forward direction of the cleaning device, and the cleaning aid member is configured to assist the first annular cleaning belt in cleaning trash.

The cleaning device to which the present disclosure relates includes the cleaning component and the cleaning aid member. The cleaning component includes a first annular cleaning belt, a first roller, and a second roller. The first roller is spaced apart from the second roller, the second roller is disposed above the first roller, and the first annular cleaning belt surrounds the first roller. In this way, a length of the first annular cleaning belt is increased for a better cleaning effect. On the other hand, the first annular cleaning belt rotatably surrounds the first roller and the second roller, so that the first annular cleaning belt is able to carry the trash on the surface to be cleaned by friction when rotating, and pick up and transmit the trash on the surface to be cleaned with the assistance of the cleaning aiding member. As a result, the cleaning device is better able to achieve a more thorough cleaning of the surface to be cleaned, with a better cleaning effect.

In family life, tedious housework takes up a lot of time and energy, and cleaning devices come into being in such a context. Some of the existing cleaning devices, such as mopping machines, generally work by rolling a roller so that a surface of the roller mops and washes a surface to be cleaned. To avoid the cleaning device from being too large and thus inconvenient for a user to operate, a volume of the existing roller is set to be small, and a surface area of the roller is limited. As a result, after the cleaning device works for a period of time, the surface of the roller quickly becomes dirty, which results in a poor cleaning effect when the cleaning roller continues to carry out the cleaning work.

Based on the problems in the prior art, with reference to FIG. 1 to FIG. 4, the present disclosure proposes a cleaning device including a cleaning component 1 and a cleaning aid member 2. The cleaning component 1 includes a first annular cleaning belt 11, a first roller 12, and a second roller 13. The first roller 12 and the second roller 13 are spaced apart, the second roller 13 is disposed above the first roller 12, and the first annular cleaning belt 11 rotatably surrounds the first roller 12 and the second roller 13. The first annular cleaning belt 11 is configured to clean a surface to be cleaned. The cleaning aid member 2 is disposed behind the cleaning component 1 along a forward direction of the cleaning device, and the cleaning aid member 2 is configured to assist the first annular cleaning belt 11 in cleaning trash.

The second roller 13 is disposed above the first roller 12, and a distance of the second roller 13 relative to the surface to be cleaned is greater than a distance of the first roller 12 relative to the surface to be cleaned. Specifically, for example, a distance between an axis of the second roller 13 and the surface to be cleaned is greater than a distance between an axis of the first roller 12 to the surface to be cleaned. The second roller 13 is disposed above the first roller 12, and of course, a height of the highest portion of the surface to be cleaned to the second roller 13 is greater than the height of the highest portion of the surface to be cleaned to the first roller 12.

The first annular cleaning belt 11 rotatably surrounding the first roller 12 and the second roller 13 refers to that the first annular cleaning belt 11 is rotatable relative to the two rollers as a whole.

The cleaning device involved in the present disclosure includes the cleaning component 1 and the cleaning aid member 2. The cleaning component 1 includes a first annular cleaning belt 11, a first roller 12, and a second roller 13, the first roller 12 and the second roller 13 are spaced apart, and the first annular cleaning belt 11 surrounds the first roller 12 and the second roller 13. Thereby, a length of the first annular cleaning belt 11 is increased, which effectively improves a contactable area between the first annular cleaning belt 11 and the surface to be cleaned, so that the first annular cleaning belt 11 is able to sufficiently stick to and transmit the trash, which makes a cleaning effect better. On the other hand, the first annular cleaning belt rotatably surrounds the first roller 12 and the second roller 13, so that the first annular cleaning belt 11 is able to carry the trash on the surface to be cleaned when rotating under an action of a friction force, and pick up and transmit the trash with the assistance of the cleaning aid member 2, so that the cleaning of some solid trash is realized. In this way, the cleaning device is able to better realize a more thorough cleaning of the surface to be cleaned, and the cleaning effect is better.

It should be noted that a forward direction of the cleaning device is a main traveling direction of the cleaning device in operation. If the cleaning device is a handheld cleaning device and the surface to be cleaned is the ground, a user needs to hold the cleaning device and push the cleaning device in the direction in which the user is traveling forward, then this direction is the forward direction of the cleaning device. In other embodiments, if the cleaning device is a cleaning robot, the forward direction is the direction in which the cleaning robot is primarily moving. In addition, the first annular cleaning belt 11 surrounds the first roller 12 and the second roller 13 to form a closed loop. The first annular cleaning belt 11 cyclically rotates along surfaces of the first roller 12 and the second roller 13 to clean the surface to be cleaned.

In some usage scenarios, the surface to be cleaned is the ground, i.e. the cleaning device is used to clean the ground. Of course, in other use scenarios, the surface to be cleaned is a wall or a window or a ceiling or other surfaces to be cleaned.

In an optional embodiment, the cleaning component 1 is disposed obliquely relative to the surface to be cleaned, and the cleaning aid member 2 is disposed at an angle below or above the cleaning component 1 along the forward direction of the cleaning device.

Optionally, referring to FIG. 3A, when the cleaning aid member 2 is disposed at an angle below the cleaning component 1 along the forward direction of the cleaning device, an outer surface of an oblique upper portion of the cleaning aid member 2 cooperates with the first annular cleaning belt 11, the first annular cleaning belt 11 rotates to cooperate with the cleaning aid member 2 to pick up the trash, and transmit the trash along an oblique upper surface of the cleaning aid member 2 under a rotating action of the first annular cleaning belt 11. Optionally, referring to FIG. 3B, when the cleaning aid member 2 is provided at an angle above the cleaning component 1 along the forward direction of the cleaning device, the outer surface of an oblique lower portion of the cleaning aid member 2 cooperates with the first annular cleaning belt 11 in close proximity, the first annular cleaning belt 11 rotates to cooperate with the cleaning aid member 2 to pick up the trash, and transmit the trash along the oblique lower surface of the cleaning aid member 2 under the rotating action of the first annular cleaning belt 11.

In an optional embodiment, referring to FIG. 3A and FIG. 4, the first annular cleaning belt 11 is formed with a transmission side 111 disposed at an incline, and the transmission side 111 is at least partially disposed opposite to the cleaning aid member 2 for transmitting the trash. The transmission side 111 cooperates with the cleaning aid member 2 to pick up the trash on the surface to be cleaned and transmit the trash to a preset position. Optionally, the transmission side 111 disposed at an incline may extend from a portion close to the surface to be cleaned toward an upper front or an upper rear portion of the cleaning device. An inclined direction of the transmission side 111 is related to that the cleaning aid member 2 is disposed at an angle below or above the cleaning component 1. As a result, an angle between the inclined transmission side 111 and the surface to be cleaned is not a right angle, and the transmission side 111 is inclined relative to the surface to be cleaned. By inclining the transmission side 111 relative to the to be cleaned surface, the trash is better transmitted.

It should be noted that, in an optional embodiment, the transmission side 111 is perpendicular to the surface to be cleaned, and the transmission side 111 cooperates with the cleaning aid member 2 to pick up the trash on the surface to be cleaned, and transmit the trash to a preset position.

In an optional embodiment, the transmission side 111, by cooperating with the cleaning aid member 2, clamps and transmits the trash in a moving direction of the transmission side 111. In this way, a height of the trash transmission is elevated, i.e., the cooperation between the transmission side 111 and the cleaning aid member 2 is capable of transmitting the trash without driven by a wind power. That is, the first annular cleaning belt 11, when rotating, cooperates with the cleaning aid member 2 to transmit the trash, and there is no need to set up a fan to vacuum the trash. In this manner, the cleaning device does not need a high-speed fan for vacuuming the trash, which is conducive to reducing a noise and a power consumption of the cleaning device.

Of course, in an optional embodiment, the trash is vacuumed by providing the fan. In this way, the trash is transmitted by the cooperation between the first annular cleaning belt 11 and the cleaning aid member 2, and at the same time be transmitted by vacuuming by the fan, for a better cleaning effect.

In an optional embodiment, the first roller 12 is configured to press a local portion of the first annular cleaning belt 11 against the surface to be cleaned to form a cleaning end, and the second roller 13 is located at an angle above the first roller 12, so that the first annular cleaning belt 11 forms the transmission side 111.

When the surface to be cleaned is a horizontal surface such as the ground, in an optional embodiment, a weight of the first roller 12 is greater than the weight of the second roller 13. As a result, the first roller 12 is heavier, and the first roller 12 is close to the ground, so as to make the local portion of the first annular cleaning belt 11 that is pressed against the surface to be cleaned to fit more tightly against the surface to be cleaned. At the same time, the corresponding friction force is increased, including the friction force between the local portion, the surface to be cleaned, and the trash. In this way, a cleaning effect is improved, especially for some solid small-particle trash and stubborn stains on the surface to be cleaned. At the same time, the first roller 12 is heavier, so that a center of gravity of the entire cleaning component 1 is lower, and when cleaning the ground, the cleaning device operates smoother on the ground.

In an optional embodiment, the weight of the first roller 12 is greater than the weight of the second roller 13, because the weight of the first roller 12 itself is greater than the weight of the second roller 13, or because the weight of the first roller 12 as a whole (e.g., including a driving member embedded in the first roller 12 and the first roller 12, or including other parts, such as a counterweight member embedded in the first roller 12 and the first roller 12), is greater than the weight of the second roller 13, which is not limited herein.

In an optional embodiment, referring to FIG. 4, the cleaning aid member 2 includes a transmission slope 22. A transmission slope 22 is disposed opposite to the transmission side 111, and the transmission slope 22 is configured to cooperate with the first annular cleaning belt 11 to assist the first annular cleaning belt 11 to transmit trash. When the cleaning device is operating, the trash is held between the transmission side 111 and the transmission slope 22, and the first annular cleaning belt 11 rotates to transmit the trash to a predetermined position under friction.

In an optional embodiment, a surface of the transmission slope 22 also form a concave-convex structure or a wavy striped structure. In this way, the friction force during transmission is increased, so as to prevent the trash from slipping during transmission.

In an optional embodiment, the transmission slope 22 is also a plane or a curved surface with a certain radius, which is not limited here.

In an optional embodiment, the transmission side 111 is at least partially parallel to the transmission slope 22 for better clamping of the trash.

In an optional embodiment, the transmission side 111 is parallel to the transmission slope 22. Of course, in an optional embodiment, the transmission side 111 is not parallel to the transmission slope 22, i.e., there is an angle between an extension surface of the transmission side 111 and the extension surface of the transmission slope 22, and optionally, a size of the angle is set according to a requirement of actual application.

In an optional embodiment, to clean up various types of trash to improve the cleaning effect, a slope of the transmission slope 22 is set to be in a certain angle range. For example, the slope of the transmission slope 22 is set to be greater than or equal to 20 degrees and less than or equal to 70 degrees. For example, the slope of the transmission slope 22 is 20 degrees, 30 degrees, or 70 degrees.

Optionally, the slope of the transmission slope 22 is set to be greater than or equal to 25 degrees and less than or equal to 50 degrees. For example, the slope is 25 degrees, 29 degrees, or 50 degrees. Or, the slope of the transmission slope is set to be greater than or equal to 28 degrees and less than or equal to 42 degrees. For example, specifically, the slope is 31 degrees, 40 degrees, etc. With such angular limitation, the effect of the cleaning device in transmitting the trash is improved, which in turn improves the cleaning effect.

In an optional embodiment, to clean up various kinds of trash and improve the cleaning effect of the cleaning device, a height of a highest point of the transmission slope 22 is set to be greater than or equal to 15 mm and less than or equal to 70 mm. For example, the height is 18 mm, 20 mm, or 70 mm. Optionally, the height of the highest point of the transmission slope 22 is set to be greater than or equal to 20 mm, and less than or equal to 45 mm. For example, the height is 18 mm, 30 mm, or 45 mm Optionally, the height of the highest point of the transmission slope 22 is set to be greater than or equal to 20 mm, less than or equal to 40 mm. For example, the height is 20 mm, 32 mm or 40 mm. The height of the highest point of the transmission slope 22 is understood as a distance from the highest point of the transmission slope 22 to the surface to be cleaned. With such height limitation, the effect of the cleaning device in transmitting the trash is improved, which in turn improves the cleaning effect.

Optionally, the greater the slope of the transmission slope 22, the more difficult it is to transmit the trash. However, at the limited transmission height, a required transmission distance is shorter, and an overall length of the cleaning aid member 2 along the forward direction is shorter, making the size of the entire cleaning device smaller. At the same time, the smaller the slope of the transmission slope 22, the less difficult it is to transmit the trash. However, at the limited transmission height, the required transmission distance becomes longer, and the overall length of the cleaning aid member 2 along the forward direction becomes longer. Thus, in the above embodiment, by providing a parameter combination of the slope of the transmission slope 22 and the highest point of the transmission slope 22, the length of the cleaning aid member 2 is reduced while satisfying a trash transmission capacity of the cleaning device. At the same time, the height of the trash transmission is ensured, so that the recycling container 3 has a deeper trash cavity 32, which effectively reduces the volume of the cleaning device, and improves the cleaning effect.

In an optional embodiment, the cleaning aid member 2 includes a transmission portion 21, the transmission portion 21 includes a guiding plate, and a side of the guiding plate opposite to the transmission side forms the transmission slope 22. When transmitting the trash, the first annular cleaning belt 11 rotates to make the transmission side 111 cooperate with the transmission slope 22 of the transmission portion 21 to pick up the trash on the surface to be cleaned and transmit the trash to the preset position. Optionally, the transmission portion 21, as a whole, is a washboard structure to cooperate with the transmission side 111 in transmitting the trash.

Optionally, by providing the transmission section 21, a low-cost trash transmission mode is realized (without a need for an additional driving motor, etc.), which has a better support effect for the cleaning component 1.

In an optional embodiment, with reference to FIG. 3A and FIG. 4, the cleaning aiding member 2 includes an introduction portion 23. The introduction portion 23 is located on a side of an extension direction the transmission slope 22 towards the surface to be cleaned. The introduction portion 23 is configured to perform at least one of the following: assisting the cleaning component 1 to pick up the trash on the surface to be cleaned, scraping the trash on the surface to be cleaned, or cooperating with the cleaning component 1 to transmit the trash onto the transmission slope 22.

The introduction portion 23 is disposed on the side of the extension direction of the transmission slope 22 towards the surface to be cleaned, and optionally, the introduction portion 23 contacts the surface to be cleaned or keeps a slight distance from the surface to be cleaned. When the cleaning device performs a cleaning operation on the surface to be cleaned, the introduction portion 23 scrapes the trash on the surface to be cleaned or gathers the trash together during the traveling of the cleaning device. As the first annular cleaning belt 11 of the cleaning component 1 cyclically rotates, the first annular cleaning belt 11 of the cleaning component 1 cooperates with the introduction portion 23 to pick up the trash and transmit the trash to between the transmission side 111 and the transmission slope 22.

Additionally, to improve the effect of picking up trash by the cleaning device, in an optional embodiment, with reference to FIG. 7 and FIG. 8, the introduction portion 23 includes a first introduction slope 231. The first introduction slope 231 forms a first angle with the surface to be cleaned, the transmission slope 22 forms a second angle with the surface to be cleaned, and the first angle is greater than or equal to the second angle. In this way, a greater opening 31 is formed between the first introduction slope 231 and the first annular cleaning belt 11, so as to enable the trash to better enter the opening 31, and under the rotation of the first annular cleaning belt 11, pick up and transmit the trash to between the transmission side 111 and the transmission slope 22, and allow the first introduction slope 231 to have a stronger resistance to the surface to be cleaned. Specifically, in some embodiments, the first angle is set to 90 degrees. In addition, in some embodiments, the introduction portion is made of a flexible material that remains against the surface to be cleaned when the cleaning device moves.

In an optional embodiment, with reference to FIG. 7 and FIG. 8, the introduction portion 23 further includes a second introduction slope 232. The second introduction slope 232 is disposed between the first introduction slope 231 and the transmission slope 22, and the transmission slope 22 and the second introduction slope 232 are located on a same plane, so that a connection between the introduction portion 23 and the transmission portion is strengthened for a better transmission of the trash.

In an optional embodiment, with reference to FIG. 7 and FIG. 8, the cleaning aid member 2 further includes a side stop portion 24 disposed on the transmission portion 21. The side stop portion 24 is disposed at at least one end of the transmission slope 22 in a first direction to stop the trash from falling. The first direction is parallel to an axial direction of the first roller 12. In an optional embodiment, the side stop portion 24 includes a first side stop portion 241 and a second side stop portion 242 disposed opposite to each other along the first direction, so that the trash is stopped from falling from the two sides. As a result, the first annular cleaning belt 11 ensures that the trash is located between the transmission side 111 and the transmission slope 22 when transmitting the trash.

In an embodiment of the present disclosure, with reference to FIGS. 2-4, the cleaning device further includes the recycling container 3 for collecting the trash. The recycling container 3 includes an opening 31 disposed behind the transmission slope 22 of the cleaning aid member 2 along the forward direction of the cleaning device. In this way, the cleaning device cleans the surface to be cleaned as it moves forward, and the picked up trash is transmitted along the transmission slope 22 into the recycling container 3. As a result, the recycling container 3 is disposed to collect the transmitted trash first, so that it is easy for the cleaning device to continue operating.

In an optional embodiment, the recycling container 3 includes the trash cavity 32 connected to the opening 31. The trash enters the trash cavity 32 through the opening 31 from the transmission slope 22 and/or the transmission side 111. Optionally, the trash enters the trash cavity 32 through the opening 31 via the transmission slope 22 and the transmission side 111, the trash may also enter the trash cavity 32 through the opening 31 via the transmission side 111 only, or the trash may also enter the trash cavity 32 through the opening 31 via the transmission slope 22 only.

Additionally, due to the inclined setting of the transmission slope, the recycling container is disposed behind the transmission slope. As a result, the opening of the recycling container needs to be set higher relative to an end of the transmission slope, which increases a height of the recycling container, enlarges a volume of the recycling container, and enables the recycling container to have a greater capacity to collect more trash.

In the optional embodiment, referring to FIG. 3A, in order to ensure that the transmission side 111 adequately transfers the trash into the trash cavity 32, the length of the transmission side 111 may be greater than the length of the transmission slope 22, so as to ensure that when the first annular cleaner belt 11 rotates, the transmission side 111 would adequately carry away the trash of the transmission slope 22. Specifically, some drier trash on the surface to be cleaned is gripped by the transmission slope 22 and the transmission side 111 and transmitted by the rotating annular cleaning belt to the end of the transmission slope 22, and the first annular cleaner belt 11 continues to rotate, then the transmission side 111 would continue to transmit the trash until the trash is detached from the transmission slope 22 and falls into the trash cavity 32 through the opening 31 of the recycling container 3 under the effect of gravity. Additionally, some trash on the surface to be cleaned is relatively wet, or the trash itself has a viscous substance, and such trash is easy to stick to a surface of the first annular cleaning belt 11 when picked up by the first annular cleaning belt 11, and such trash is mainly stuck to the transmission side 111 when transmitted between the transmission side 111 and the transmission slope 22. When such sticky trash is transmitted out of the transmission slope 22, it does not fall directly into the trash cavity 32. For such a case, in an optional embodiment, the cleaning device is provided with a component for scraping the trash down, which scraps off the trash that is transmitted to the transmission slope 22 but is still sticking to the transmission side 111, into the trash cavity 32. Of course, the component for scraping the trash down may not be provided, and the user may manually scrape such trash off in use.

In an optional embodiments, the length of the transmission side 111 is the same as the length of the transmission slope 22. In this way, the drier trash is transmitted to the end of the transmission side 111 and the transmission slope 22 by the rotating annular cleaning belt. The first annular cleaning belt continues to rotate, then the trash simultaneously leaves the transmission side 111 and the transmission slope 22, and falls into the trash cavity 32 through the opening 31 of the recycling container 3 under the effect of gravity.

In an optional embodiment, the length of the transmission side 111 is less than the length of the transmission slope 22. In this way, the first annular cleaning belt 11 transmits the trash to the end of the transmission side 111, then the trash gathers on the transmission slope 22. When the gathered trash reaches a certain volume, the trash is detached from the transmission slope 22 and falls into the trash cavity 32 through the opening 31 of the recycling container 3 under the effect of gravity.

In an optional embodiment, with reference to FIG. 3A, the recycling container 3 is at least partially disposed behind the cleaning aid member 2 along the forward direction of the cleaning device.

In an optional embodiment, the recycling container 3 is partially disposed behind the cleaning aid member 2 and partially disposed below the cleaning aid member 2. That is, the recycling container 3 and the cleaning aid member 2 form a partially staggered relationship in terms of spatial position, so that a space underneath the cleaning aid member 2 is utilized to maximize the capacity of the recycling container 3. Additionally, as the trash falls into the trash cavity 32 of the recycling container 3 under the effect of gravity after the trash is detached from the cleaning aid member 2, by partially disposing the opening 31 under the cleaning aid member 2, the falling trash is better taken.

In an optional embodiment, the entire recycling container 3 is disposed behind the cleaning aid member 2.

In an optional embodiment, the transmission side 111 includes a first region 1111 opposite to the transmission slope 22 and a second region 1112 disposed at an angle above the first region 1111. In an optional embodiment, a ratio of lengths of the first region 1111 to the second region 1112 along an extension direction of the transmission slope is greater than 1. This allows for a better recycling of the trash.

On an optional embodiment, a length of the opening 31 along the extension direction of the transmission slope is greater than or equal to 10 mm and less than or equal to 60 mm, such as 20 mm, 40 mm, or 60 mm. Optionally, the length of the opening 31 along the extension direction of the transmission slope is greater than or equal to 15 mm and less than or equal to 25 mm, such as 15 mm, 20 mm, or 25 mm.

In an optional embodiment, when the transmission side 111 is disposed inclined, the opening 31 of the recycling container 3 is disposed partially inclined, and the inclined portion of the opening 31 is at least partially disposed opposite to the second region 1112. As a result, the opening 31 of the recycling container 3 is able to cooperate as much as possible with the transmission side 111 to better take the dropped trash, and an excessive gap between the transmission side 111 and the opening 31 of the recycling container 3 is avoided, and the trash is unlikely to fall outside the recycling container 3. In an optional embodiment, the opening 31 of the recycling container 3 is also wholly inclined, and disposed at least partially opposite to the second region 1112.

In an optional embodiment, referring to FIG. 3A to FIG. 5, the cleaning aid member 2 is provided with a first snap member 25. Optionally, the first snap member 25 is disposed on a side of the cleaning aid member 2 close to the second region 1112, and the recycling container 3 is provided with a second snap member 33 that snaps into the first snap member 25. In this way, the recycling container 3 and the cleaning aid member 2 are detachably connected, which is convenient for the user to dump the trash in the recycling container 3, and a snap-on connection is convenient for the user to operate. Optionally, in some embodiments, the first snap member 25 is a groove, and the second snap member 33 is a convex portion that snaps to the groove. Of course, in other embodiments, the groove and the convex portion are disposed in opposite positions, i.e., the first snap member 25 is the convex portion, and the second snap member 33 is the groove that snaps to the convex portion.

In the other embodiments, the cleaning aid member 2 and the recycling container 3 are also connected by a magnetic member, which is not limited here.

In an optional embodiment, the cleaning device is not disposed with the recycling container 3. For example, a disposable trash bag is fixed to the cleaning device before the cleaning device operates, and the trash transmitted by the cleaning component 1 and the cleaning aid member 2 is collected into the disposable trash bag when the cleaning device operates.

It should be noted that the trash includes both shaped solid trash, such as paper balls and fruit peels, and flowing liquid trash, such as sewage. Of course, the solid trash may contain liquids, such as absorbent paper towels, etc., but such trash is also shapely and is able to be picked up, so that the trash is regarded as the solid trash.

In the above embodiment, by setting the first cleaning component 1 inclined as a whole and forming the transmission side 111 and the transmission surface 22 that are inclined, a transmission height of the trash is effectively increased as compared to directly laying the first annular cleaning belt flat on the ground. In this way, the recycling container 3 has a better depth, thereby increasing a size of the trash cavity 32 of the recycling container 3, and improving the cleaning effect and the cleaning power.

To improve the cleaning effect of the surface to be cleaned, a water-absorbable cleaning cloth is used to clean the surface to be cleaned in a process of home cleaning or office cleaning. In this way, the cleaning device not only absorbs the sewage on the surface to be cleaned through the cleaning cloth, but also wet the cleaning cloth before cleaning, so that the wet cleaning cloth cleans stubborn stains on the floor better. When the cleaning cloth absorbs too much sewage, the user needs to squeeze out the sewage from the cleaning cloth to better continue the cleaning operation, but manually removing the cleaning cloth and squeeze out the sewage is undoubtedly very troublesome.

In the present disclosure, the first annular cleaning belt 11 is made of an absorbable material, i.e., a cleaning cloth being able to absorb the sewage, and the first annular cleaning belt 11 is configured to absorb the sewage from the surface to be cleaned. In view of the existing problem of a troublesome extrusion of the sewage, the cleaning device involved in the present disclosure further includes a first scraper 41. The first scraper 41 is configured to scrape the sewage from the first annular cleaning belt 11 to make the sewage fall into the recycling container 3 of the cleaning device.

In an optional embodiment, referring to FIG. 3A and FIG. 4, the first annular cleaning belt 11 abuts against the second roller 13 to form a bending portion 112. The first scraper 41 abuts against the bending portion 112, and the end of the first scraper 41 points toward the second roller 13. Specifically, the first roller 12 is configured to press a local portion of the first annular cleaning belt 11 against the surface to be cleaned, the second roller 13 is located at an angle above the first roller 12, and the first annular cleaning belt 11 rotates in the direction of the second roller 13 after sucking up the surface to be cleaned, and the bending portion 112 is located at an end of the cleaning component 1. In this way, when the cleaning device is in operating, the first scraper 41 is able to make the sewage to drip off as soon as possible after the sewage is scraped out of the bending portion 112, so as not to affect the subsequent cleaning operation.

Optionally, by abutting the first scraper against the bending portion 112, and the end of the first scraper 41 pointing toward the second roller 13, the first scraper 41 and the second roller 13 cooperate in squeezing the first annular cleaning belt 11 disposed between them, thereby improving a scraping ability.

In an optional embodiment, it is appreciated that, as the cleaning component 1 is rotationally disposed relative to the cleaning aid member 2, the end of the first scraper 41 points to a rotation axis of the cleaning component 1 rotationally disposed relative to the cleaning aid member 2. In this way, a gap between the end of the first scraper 41 and the cleaning component 1 remains constant and is not affected by the rotation of the cleaning component 1.

In an optional embodiment, with reference to FIG. 19. FIG. 19 shows the first scraper 41 disposed in various positions. Taking a horizontal plane where an axis of the second roller 13 is located as a reference plane, an angle A between a contact position of the first scraper 41 and an outer surface 114 of the first annular cleaning belt 11 and the reference plane is greater than or equal to 0 degrees, and less than or equal to 120 degrees, for example, the angle A is 0 degrees, 60 degrees, or 120 degrees. In this way, the angle between a pointing direction of the end of the first scraper 41 and the reference plane ensures that the sewage falls into the recycling container 3 after the first scraper 41 scrapes the sewage out.

In an optional embodiment, the first annular cleaning belt 11 is made of the absorbable material. Of course, to improve the cleaning effect, the first annular cleaning belt 11 is disposed to include a multilayered structure, for example, the first annular cleaning belt 11 includes a villus layer. For the first annular cleaning belt 11 including the villus layer, an interference amount between the first scraper 41 and the first annular cleaning belt 11 is greater than or equal to 30% of a thickness of the villus layer, and is less than or equal to 80% of the thickness of the villus layer, for example, the interference amount is 30%, 50%, or 80%. It should be noted that the villus layer may be dry or wet. The interference amount may be understood as a depth of the first scraper 41 against the villus layer when the villus layer is dry. In the other embodiment, the interference amount between the first scraper 41 and the first annular cleaning belt 11 is greater than or equal to 50% of the thickness of the villus layer, and less than or equal to 70% of the thickness of the villus layer, for example, the interference amount is 50%, 60%, or 70%.

By setting a suitable interference amount, a certain contact is ensured even after the villus layer is moistened, and a cleanliness of the first annular cleaning belt 11 is thus improved.

Optionally, the interference amount refers to an overlapped portion between the first scraper 41 and the first annular cleaning belt 11. When the angle A reaches a certain angle and under a tension, the sewage scraped out by the first scraper 41 forms, between the first scraper 41 and the first annular cleaning belt 11, a water mass 100 that re-infiltrates the first annular cleaning belt 11. Thereby, by setting the position and the angle of the first scraper 41, the water scraped out by the first scraper 41 forms a water mass 100 between a scraper and the first annular cleaning belt 11, and the water mass 100 is able to re-infiltrate the first annular cleaning belt 11. In this way, water resources are fully utilized, and the annular cleaning belt after sufficient infiltration has the better cleaning effect, which improves a cleaning strength of the cleaning device.

Optionally, under a counterclockwise rotation of the annular belt 11, the sewage scraped out is driven by the annular belt 11 to move toward a scraping member 2 and thus gathers together to form the water mass 100, or the sewage overcomes the gravity under the effect of inertia and thus gathers together to form the water mass.

In an optional embodiment, the angle A is greater than or equal to 30 degrees and less than or equal to 70 degrees. In this way, the water mass formed is relatively small, and is more likely to fall off into the recycling container.

In an optional embodiment, the angle A is greater than or equal to 32 degrees and less than or equal to 50 degrees.

In an optional embodiment, the angle A is greater than 70 degrees and less than 120 degrees, so as to make the formed water mass greater, which has a better infiltration effect on the first annular cleaning belt 11.

When the cleaning device starts to work, the water is still relatively clean, and the water formed after the first scraper 41 scrapes the water out of the first annular cleaning belt 11 is less, and the water mass 100 formed is still relatively small. Due to a surface tension of the water mass 100, the water does not drip. As a result, the water mass 100 is able to be absorbed into the first annular cleaning belt 11 again, to infiltrate the first annular cleaning belt 11. When the cleaning device works for a longer period of time, the water is dirtier, the first scraper 41 scrapes more water out of the first annular cleaning belt 11, and forms a greater water mass 100. When a preset water amount is reached, the sewage drips down to the recycling container 3 under the effect of gravity, thus realizing a recovery of the sewage. Thereby, through an ingenious setting of the position of the first scraper 41, the sewage is utilized to a certain extent to infiltrate the first annular cleaning belt 11 again, and at the same time, a function of the first scraper 41 to scrape the sewage is still realized, so as to ensure the cleaning effect of the first annular cleaning belt 11.

In an optional embodiment, referring to FIG. 9, the cleaning device further includes a liquid discharge component 15. The liquid discharge component 15 is configured to discharge a cleaning liquid towards the first annular cleaning belt 11. One end of the cleaning device close to the surface to be cleaned is the cleaning end, and the cleaning end is located at upstream of the first scraper 41 along a rotation direction of the first annular cleaning belt 11. The liquid discharge component 15 is disposed at upstream of the cleaning end along the rotation direction of the annular cleaning belt. In a specific application, before cleaning the surface to be cleaned, the cleaning liquid is output toward the first annular cleaning belt 11 through the liquid discharge component 15, and the first annular cleaning belt 11 rotates to the cleaning end after being infiltrated by the cleaning liquid. The first annular cleaning belt 11 mops the surface to be cleaned at the cleaning end, thereby realizing cleaning, disinfection, or surface caring of the surface to be cleaned by the cleaning device. After mopping the surface to be cleaned, the first annular cleaning belt 11 is rotates to a set region of the first scraper 41, and the surface of the first annular cleaning belt 11 is scrapped by the first scraper 41 to scrape the sewage off. Of course, in the specific application, as an optional embodiment, the cleaning device does not have the liquid discharge component 15, and in an optional embodiment, the cleaning device is used as a sweeper or a dust pusher.

In an optional embodiment, with reference to FIG. 1, the cleaning device is the handheld cleaning device, and when in use, the user holds the cleaning device and flexibly controls a trajectory of the cleaning device traveling on the surface to be cleaned according to a dirty region of the surface to be cleaned. Optionally, the cleaning device includes a handheld rod 6, a cleaning liquid tank, and a chassis 5 rotationally connected to a bottom end of the handheld rod 6. The cleaning liquid tank is disposed in the handheld rod 6, the cleaning component 1 and the cleaning aid member 2 are disposed on the chassis 5, and the cleaning liquid tank is connected to the liquid discharge component 15 to output the cleaning liquid to the liquid discharge component 15. Of course, in the specific application, as an optional embodiment, the cleaning device is not disposed with the cleaning liquid tank, and a supply of the liquid to the liquid discharge component 15 is realized through an external pipeline.

In an optional embodiment, with reference to FIGS. 15-16, the cleaning device further includes a flip cover 14. The flip cover is disposed on a side of the cleaning component 1 away from the cleaning aid member. Thus, the flip cover 14 is disposed to protect the cleaning belt component and to enable a synchronized rotation of the flip cover when the cleaning belt component is rotated and adjusted, so as to prevent an interference on the rotation of the cleaning belt component. The liquid discharge component 15 and/or the first scraper 41 are disposed on the flip cover 14.

In an optional embodiment, the liquid discharge component 15 is disposed at downstream of the first scraper 41 along the rotation direction of the first annular cleaning belt 11, so that the liquid output from the liquid discharge component 15 is not immediately scraped by the first scraper 41, instead, the liquid output from the liquid discharge component 15 infiltrates the first annular cleaning belt 11 for a certain period of time.

In an optional embodiment, the liquid output by the liquid discharge component 15 includes at least one of the following liquids: water, a detergent, a sanitizer, a wax solution, a care solution. When the liquid output by the liquid discharge component 15 is clear water or the detergent, a main cleaning component 1 mops and wipes the surface to be cleaned, so as to clean the surface to be cleaned to at least remove stains and dirt from the surface to be cleaned. When the liquid output from the liquid discharge component 15 is a sanitizer, the main cleaning component 1 mops and wipes the surface to be cleaned, the main cleaning component 1 cleans and sanitizes the surface to be cleaned. When the liquid output from the liquid discharge component 15 is the wax solution or the care solution, the main cleaning component 1 mops and wipes the surface to be cleaned, and the main cleaning component 1 waxes the surface to be cleaned to care for the surface to be cleaned or perform other surface cares on the surface to be cleaned.

In an optional embodiment, referring to FIG. 11, the cleaning device also includes a second scraper 42 for scraping off the trash from the surface of the first annular cleaning belt 11.

In an optional embodiment, the second scraper 42 is mainly used to scrape off solid trash, etc. The interference amount between the first scraper 41 and the first annular cleaning belt 11 is greater than an interference amount between the second scraper 42 and the first annular cleaning belt 11. Thereby, the first scraper 41 is able to squeeze the first annular cleaning belt 11 more sufficiently as compared to the second scraper 42, and the first scraper 41 is able to scrape water out of the first annular cleaning belt 11 more sufficiently. In addition, the interference amount between the second scraper 42 and the first annular cleaning belt 11 may also be a negative value, i.e., the second scraper 42 is not in direct contact with the first annular cleaning belt 11 but is disposed in a spaced apart manner. The second scraper 42 scrapes down the trash protruding from the surface of the first annular cleaning belt 11.

In an optional embodiment, referring to FIGS. 10-11, the first annular cleaning belt 11 includes an inner surface 113 and an outer surface 114, the end of the second scraper 42 abuts against the outer surface 114, and the end of the first scraper 41 abuts against the outer surface 114 and squeezes in the direction toward the inner surface 113. A spacing between the end of the second scraper 42 and the inner surface 113 is greater than the spacing between the end of the first scraper 41 and the inner surface 113. In this way, it is ensured that the second scraper 42 scrapes off the solid waste on the surface of the first annular cleaning belt 11, and the first scraper 41 scrapes off the sewage from the first annular cleaning belt 11 by squeezing. Specifically, as the end of the first scraper 41 abuts against the outer surface 114 and squeezes in the direction toward the inner surface 113, the first scraper 41 continues to squeeze the first annular cleaning belt 11 when the first annular cleaning belt 11 rotates, so that the first annular cleaning belt 11 rotates while the first scraper 41 scrapes off the sewage on the first annular cleaning belt 11.

In an optional embodiment, referring to FIG. 11, the second scraper 42 is disposed on the cleaning aid member 2 or the recycling container 3, and located between the first annular cleaning belt 11 and the recycling container 3. Specifically, the second scraper 42 is disposed in a position such that the trash scraped off from the first annular cleaning belt 11 is allowed to enter the recycling container 3.

Exemplarily, the interference amount between the end of the second scraper 42 for scraping off the trash and the surface of the first annular cleaning belt 11 is greater than or equal to 0.5 mm, and less than or equal to 2 mm, for example, the interference amount is 0.5 mm, 1 mm, or 2 mm. In this way, a better cleaning effect is achieved.

It is noted that, in an optional embodiment, the interference amount is expressed as a percentage or as a length.

In an optional embodiment, the trash cavity 32 includes a first cavity and a second cavity disposed sequentially along the forward direction. The first cavity is configured to accommodate the trash scraped off by the second scraper, and the second cavity is configured to accommodate the trash scraped off by the first scraper.

The opening 31 includes a first sub-opening connected to the first cavity and a second sub-opening connected to the second cavity.

Optionally, the first cavity is mainly used to accommodate the solid trash, such as a wet tissue, a fruit peel, etc., and the second cavity is mainly used to accommodate liquid trash, such as the sewage, etc., so as to realize a solid-liquid separation, which is conducive to the cleaning of the recycling container 3.

In an embodiment of the present disclosure, with reference to FIGS. 1-4, the cleaning device further includes the chassis 5, and the cleaning component 1 and the cleaning aid member 2 are both disposed on the chassis 5.

When cleaning the surface to be cleaned, due to different sizes of the solid waste on the surface to be cleaned, and the schemes for picking up and transmitting the waste provided the above embodiments are sometimes limited by the sizes of the waste. As a result, the waste of different sizes may not be fully pick up and transmitted.

In an optional embodiment, when the cleaning device cleans the surface to be cleaned, the cleaning component 1 is capable of adjusting a gap between the cleaning component 1 and the surface to be cleaned, i.e., the gap from a bottom of the cleaning component 1 to the surface to be cleaned is adjustable. In this way, the cleaning component 1 is able to pick up the trash of different sizes on the surface to be cleaned more easily.

In an optional embodiment, when the cleaning component 1 cleans the surface to be cleaned, when there is a great piece of trash, the cleaning component 1 automatically adjusts the gap between the cleaning component 1 and the surface to be cleaned by abutting against the trash, so that the trash passes between the cleaning component 1 and the surface to be cleaned and is transmitted to the cleaning aid member 2.

In an optional embodiment, referring to FIG. 3A, the cleaning component 1 includes a cleaning end 115 close to the surface to be cleaned when the cleaning device cleans the surface to be cleaned. When the cleaning end 115 contacts the trash on the surface to be cleaned, the cleaning component 1 is capable of automatically adjusting the gap between the cleaning end 115 and the surface to be cleaned based on the size of the trash. In a specific application, when the cleaning device performs the cleaning operation on the surface to be cleaned, when there is a great-sized trash, the trash is pressed against the cleaning end 115 and the cleaning component 1 is lift up as a whole, so that the great-sized trash is transmitted through the cleaning component 1 to between the first annular cleaning belt 11 and the cleaning aid member 2, thereby realizing an effect that the cleaning component 1 automatically adjusts the gap between the cleaning component and the surface to be cleaned according to the size of the trash, so that the cleaning device removes the trash of different sizes.

In an optional embodiment, a ratio of an adjustment value of the gap that the cleaning component 1 is capable of adjusting to the length of the opening 31 of the recycling container 3 is greater than or equal to 0.8 and less than or equal to 2.

In an optional embodiment, when the cleaning device cleans the surface to be cleaned, the cleaning component 1 is capable of automatically adjusting a gap between the cleaning component 1 and the transmission slope 22, i.e., the gap between the transmission side 111 of the cleaning component 1 and the transmission slope 22 is adjustable. This way avoids a situation in which the transmission side 111 and the transmission slope 22 are unstable in gripping the smaller trash during the transmission of the smaller trash, which in turn leads to a situation in which the trash is not transmitted effectively. At the same time, the situation in which the greater trash is caught between the transmission side 111 and the transmission slope 22, thereby blocking the transmission is also avoided.

In an optional embodiment, the transmission side 111 has a certain deformability and is able to deform when squeezed by the trash, thereby realizing an adjustable gap between the transmission side 111 and the transmission slope 22.

In an optional embodiment, when the cleaning device cleans the surface to be cleaned, the cleaning component 1 is able to automatically adjust the gap between the transmission side 111 and the transmission slope 22 based on the size of the trash. Thus, the cleaning device makes it possible for the trash of different sizes to be transmitted between the transmission side 111 and the transmission slope 22, thereby effectively preventing the trash from getting stuck between the transmission side 111 and the transmission slope 22 in the process of transmission.

In an optional embodiment, the first annular cleaning belt 11 has a certain degree of elasticity and deformation capability, so that when the trash passes through the transmission side 111 and the transmission slope 22, the first annular cleaning belt 11 deforms under an extrusion of the trash, thereby automatically adjusting the gap between the first annular cleaning belt 11 and the transmission slope 22, i.e., realizing the gap adjustment between the cleaning component 1 and the transmission slope 22.

Optionally, the automatic adjustment referred to in the present disclosure is not a self-regulation realized by means of an electric control, a manual initiative, etc., but rather the adjustment is realized under a certain external environmental factor such as being squeezed by the trash, being abut against, etc., under the effect of an external force.

In an optional embodiment, the first roller 12 is configured to press the cleaning end 115 of the first annular cleaning belt 11 against the surface to be cleaned. The first roller 12 includes an elastic section 123 and/or a flexible section. The elastic section 123 and/or the flexible section is used to deform as the trash passes by. In this way, when there is trash with a great size, the cleaning component 1 moves over the trash, and the first roller 12 deforms the elastic section 123 and/or the flexible section under the pressure of the trash, so as to increase the gap between the cleaning end 115 and the surface to be cleaned, which facilitates a passage of the trash, thereby enabling the cleaning component 1 and the cleaning aid member 2 to cooperate in picking up the trash with the great size.

As shown in FIG. 25, the first roller 12 includes the elastic section 123, and the elastic section 123 is at least used to deform as the trash passes by and thus to adjust the gap between the elastic section 123 and the surface to be cleaned. In this way, when the trash with great size is taken, the trash squeezes the elastic section 123 as it passes through a portion of the first annular cleaning belt 11 disposed around the first roller 12, the elastic section 123 undergoes the deformation, which increases the gap between the elastic section 123 and the surface to be cleaned, as well as the gap between the first annular cleaning belt 11 set on the elastic section 123 and the surface to be cleaned, which is conducive to the passage of the trash with the great size, so that the cleaning device is able to easily taking the trash with the great size. After completing a guiding of the trash with the great size, the elastic section 123 is restored to an original state under the effect of its own elastic force, and a distance between the portion of the first annular cleaning belt 11 surrounding the first roller 12 and the surface to be cleaned is restored to the original state, so as to accommodate the trash with smaller size. Thus, the cleaning device provided in the embodiment is able to efficiently take both the trash with great and small sizes, which improves the cleaning effect.

In an optional embodiment, the first roller 12 further includes a guiding section 124, the guiding section 124 is connected to the elastic section 123. By disposing the guiding section 124, on the one hand, the elastic section 123 is fixed, and on the other hand, the first annular cleaning belt 11 is guided.

In an optional embodiment, the first roller 12 includes two guiding sections 124, with the elastic section 123 connected between the two guiding sections 124. In this way, both ends of the first roller 12 guides the first annular cleaning belt 11, which improves a smoothness of the rotation of the first annular cleaning belt 11. Of course, in a specific application, as an optional embodiment, the first roller 12 includes one or three or four guiding sections 124, and there is no restriction herein on a count of the guiding sections 124.

In an optional embodiment, the guiding section 124 and the elastic section 123 are coaxially disposed to flatten the portion of the first annular cleaning belt 11 surrounding the first roller 12, which facilitates the taking of the trash. A slight axial misalignment of the guiding section 124 and the elastic section 123 is also considered to be coaxially disposed. It is appreciated that in other embodiments, the guiding section 124 and the elastic section 123 are not set coaxially.

In an optional embodiment, a radial size of the guiding section 124 is the same as a radial size of the elastic section 123. In this way, the distance between the portion of the first annular cleaning belt 11 surrounding the guiding section 124 and the surface to be cleaned is the same as the distance between the portion of the first annular cleaning belt 11 surrounding the elastic section 123 and the surface to be cleaned. Compared with the situation with a poor effect for taking the trash with small size due to different distances between the portion of the first annular cleaning belt 11 surrounding the guiding section 124 and the surface to be cleaned and between the portion of the first annular cleaning belt 11 surrounding the elastic section 123 and the surface to be cleaned (e.g., if the distance between the portion of the first annular cleaning belt 11 surrounding the guiding section 124 and the surface to be cleaned is greater than the distance between the portion of the first annular cleaning belt 11 surrounding the elastic section 123 and the surface to be cleaned, the trash with small size is less likely to be taken when being on the surface to be cleaned corresponding to the portion of the first annular cleaning belt 11 surrounding the guiding section 124), the trash is more likely to be taken.

In an optional embodiment, the length of the elastic section 123 is much greater than the length of the guiding section 124. In this way, when the trash passes through the portion of the first annular cleaning belt 11 surrounding the first roller 12, the trash is made to pass through the portion of the first annular cleaning belt 11 surrounding the elastic section 123 as much as possible, which facilitates the taking of the trash with great size as well as increasing an area for taking the trash with great size.

In an optional embodiment, the guiding section 124 is a cylindrical rod. In this way, when the guiding section 124 is disposed to be rotatable with the first annular cleaning belt 11, the rotation of the guiding section 124 is achieved, thereby reducing a resistance to the first annular cleaning belt 11. Of course, as an optional embodiment, it is also possible for the guiding section 124 to be a non-circular component with at least a locally curved outer surface.

In an optional embodiment, the elastic section 123 is a spring, which works similarly to a grip bar. Upon receiving an external force with at least one component force as a radial force, the elastic section 123 deforms and restores to its original state after the external force is removed. Of course, it is possible for the elastic section 123 to be some other elastic components, such as a shrapnel.

As shown in FIGS. 26-28, in an optional embodiment, the first roller 12 includes a flexible section 125 that includes a flexible layer 126. The cleaning end 115 is deformable as the trash passes by. In this way, the first roller 12 is made flexible, and when the external force squeezes the first roller 12, the first roller 12 deforms. So when the trash passes through the cleaning end 115, the force on the cleaning end 115 is transmitted to the first roller 12, the first roller 12 undergoes the deformation, and the cleaning end 115 undergoes the deformation with the first roller 12. When the cleaning device takes the trash with great size, and when the trash passes the cleaning end 115, the first roller 12 is squeezed, which causes the first roller 12 to deform, and the cleaning end 115 deforms accordingly. In this way, the gap between the cleaning end 115 and the surface to be cleaned is increased, which is conducive to the passage of the trash with great size, so that the cleaning device is able to take the trash with great size easily. After completing the guiding of the trash with great size, the flexible layer 126 of the first roller 12 restores itself to its original state, so that the distance between the cleaning end 115 and the surface to be cleaned is restored to its original state to accommodate the trash with smaller size. Thus, the cleaning device provided in the embodiment is able to efficiently take both trash with greater and smaller sizes, which improves the cleaning effect.

In an optional embodiment, a thickness of the flexible layer 126 is not less than 5 mm. In this way, at least an outer layer of the first roller 12 is flexible enough and the deformation of the flexible layer 126 ensures the passage of the trash when the trash with great size is taken. In a specific application, the thickness of the flexible layer 126 is 7 mm, 9 mm, 16 mm, 20 mm, 43 mm, 48 mm, 55 mm, etc.

In an optional embodiment, the thickness of the flexible layer 126 is greater than or equal to 10 mm and less than or equal to 60 mm. In this way, on the one hand, the outer layer of the first roller 12 is made flexible enough so that when the trash with great size is taken, the deformation of the flexible layer 126 ensures that the trash passes through, and on the other hand, the volume of the first roller 12 is not too great and does not occupy too much space. In a specific application, the thickness of the flexible layer 126 is 10 mm, 32 mm, 38 mm, 42 mm, 46 mm, 49 mm, 52 mm, 54 mm, 57 mm, or 60 mm.

In an optional embodiment, the first roller 12 includes a center bearing shaft 127, and the flexible layer 126 is disposed around a circumference of the center bearing shaft 127. The center bearing shaft 127 is disposed for supporting the flexible layer 126.

In an optional embodiment, the flexible layer 126 includes a plurality of flexible sub-layers 128, the plurality of flexible sub-layers 128 are spaced apart along a circumferential direction of the center bearing shaft 127. Specifically, the plurality of flexible sub-layers 128 are disposed along a circumferential direction of the center bearing shaft 127, with gaps between adjacent flexible sub-layers 128, so that when the trash passes the cleaning end 115, no matter squeezed onto the flexible sub-layers 128 or squeezed to the gap between two flexible sub-layers 128, the cleaning end 115 deforms. It should be noted that there may be two, three, or four, etc. flexible sub-layers 128, and there is no limitation herein on the count of the flexible sub-layers 128.

In an optional embodiment, the first roller 12 further includes a plurality of rigid support sub-layers 129. The plurality of rigid support sub-layers 129 are spaced apart along a circumferential direction of the flexible layer 126. Specifically, the plurality of rigid support sub-layers 129 are disposed along the circumference of the flexible layer 126, with gaps between adjacent rigid support sub-layers 129, so that when the trash passes the cleaning end 115, no matter squeezed to the rigid support sub-layers 129 or to the gap between two rigid support sub-layers 129, the cleaning end 115 deforms. When the trash is squeezed into the rigid support sub-layers 129, the squeezing pressure is transmitted to the flexible layer 126 through the rigid support sub-layers 129, thereby causing the cleaning end 115 to deform. It should be noted that there may be two, three, or four, etc. rigid support sub-layers 129, and there is no limitation on the count of the rigid support sub-layers 129 herein.

In an optional embodiment, at least one section of the first roller 12 along the axial direction of the first roller 12 is the flexible section 125, and the flexible section is entirely composed of the flexible layer 126.

In an optional embodiment, the first roller 12 may be all flexible sections 125, which is not specifically limited herein.

In the above embodiment, by making the gap of the cleaning component 1 relative to the cleaning aid member 2 and/or the surface to be cleaned adjustable, a handling of the trash with great size on the surface to be cleaned is facilitated. Compared to existing roller brush scrubbers (which are not able to clean the trash with great size and gets stuck with the trash with greater size), there is no need for sweeping the floor before washing the floor, and instead, the sweeping and washing are synchronized, which greatly improves the convenience of cleaning. Moreover, the first cleaning component 1 is inclined as a whole and forms the inclined transmission side 111 and the inclined transmission slope 22. Compared to the roller brush scrubbers, the transmission height of the trash is effectively increased, so that the recycling container 3 has a better depth, thereby increasing the size of the trash cavity 32 of the recycling container 3, which is more conducive to cleaning the trash with great volumes, thereby increasing the cleaning effect and the cleaning power.

In an optional embodiment, the first roller 12 includes the elastic section 123. The elastic section 123 is at least used to deform when the trash passes by. In this way, when the cleaning component 1 picks up the trash with great volume, when the trash passes the portion of the first roller 12 surrounded by the annular cleaning belt, the trash squeezes the elastic section 123, making the elastic section 123 to deform, so as to increase the gap between the portion and the surface to be cleaned, which facilitates the passage of the trash with great volume, so that the cleaning device is able to pick up the bulky trash with great volume easily. After completing the picking up and the transmission of the trash with great volume, the elastic section 123 restores to the original state under the effect of its own elasticity, and the distance between the portion of the first annular cleaning belt 11 surrounding a first guiding component and the surface to be cleaned returns to its original state to accommodate the trash with small volume. Thereby, the cleaning device is able to efficiently pick up both trash with great and small volumes, so as to improve the cleaning effect.

Optionally, in an optional embodiment, the elastic section 123 is a spring. Of course, in an optional embodiment, the elastic section 123 is some other elastic component, such as the shrapnel.

In an optional embodiment, the first roller 12 includes the flexible section, optionally, the surface of the flexible section is the flexible layer made of a deformable material. In this way, when the trash passes the portion of the first roller 12 surrounded by the annular cleaning belt, the trash squeezes the flexible section, making the flexible section to deform, so as to increase the gap between the portion and the surface to be cleaned, which facilitates the passage of the trash with great volume, so that the cleaning device is able to pick up the bulky trash with great volume easily. After picking up and transmitting the trash with great volume, the flexible section restores to its original state, and the distance between the portion of the first annular cleaning belt 11 surrounding the first guiding component and the surface to be cleaned restores to its original state to accommodate the trash with small volume.

In an optional embodiment, the first roller 12 includes both the elastic section 123 and the flexible section, thereby handling the trash with different volumes.

In an optional embodiment, referring to FIG. 12, the outer surface 114 of the first annular cleaning belt 11 is provided with a herringbone pattern 16, and an opening direction of the herringbone pattern 16 is the rotation direction of the first annular cleaning belt 11. Thereby, the herringbone pattern 16 is able to gather the trash into the middle of the first annular cleaning belt 11, better collect the trash on the surface to be cleaned, and clean the surface to be cleaned more effectively.

In an optional embodiment, the first annular cleaning belt 11 includes the villus layer. By adopting above plan, on the one hand, the first annular cleaning belt 11 is able to closely press against the surface to be cleaned under the effect of the first roller 12 and the second roller 13 by their own gravity or by the external force to clean the surface to be cleaned, which helps to improve the cleaning effect of the cleaning device in removing the trash, the stains, and the liquids on the surface to be cleaned; on the other hand, a noise generated when the first annular cleaning belt 11 presses against the surface to be cleaned and moves on the surface to be cleaned is reduced. In addition, the first annular cleaning belt 11 is made to have a certain degree of absorbency, so as to improve the cleaning ability of the first annular cleaning belt 11.

In an optional embodiment, the thickness of the villus layer is between 5 mm and 8 mm, such as 5 mm, 7 mm, or 8 mm.

In an optional embodiment, the villus layer includes a first villus layer and a second villus layer. The second villus layer is harder than the first villus layer, and the area of the second villus layer is smaller than an area of the first villus layer.

Optionally, the second villus layer is disposed in an array or in spaced stripes bent along the axial direction of the first annular cleaning belt 11 or extended in a straight line along the axial direction of the first annular cleaning belt 11, which increases a cleaning capacity and improves the cleaning effect on the stubborn stains.

In an optional embodiment, referring to FIG. 15, the cleaning device further includes a traveling wheel 51. The traveling wheel 51 is disposed on the chassis 5 and in contact with the surface to be cleaned, and the traveling wheel 51 is configured to reduce a friction of the cleaning device moving on the surface to be cleaned. Thereby, the movement of the cleaning device on the surface to be cleaned is made smoother. When the cleaning device is the handheld cleaning device, the user is able to push the cleaning device more easily and with less effort during use.

In an optional embodiment, the at least one traveling wheel 51 is driven to rotate by a motor so as to drive the cleaning device to move, i.e., the cleaning device moves through an electric drive. Of course, in a specific application, the manner of driving the movement of the cleaning device is not limited to this, for example, as an optional embodiment, the cleaning device moves by a human power through the handheld rod 6; or, as another optional embodiment, the cleaning device is driven by the electric motor, or is driven by the human power through the handheld rod 6 or a handrail, i.e., the cleaning device has two driving manners, electric and human-powered, at the same time. Of course, in a specific application, as an optional embodiment, the cleaning device is not disposed with the traveling wheel 51, the moving of the cleaning device on the surface to be cleaned is driven by the first annular cleaning belt 11.

In an optional embodiment, the cleaning device further includes a roller disposed on the transmission portion 21 and between the recycling container 3 and the introduction portion 23. The roller is configured to contact the surface to be cleaned. As a result, the space of the transmission portion is fully utilized to make the cleaning device more compact without occupying the space of the recycling container 3. Further, the transmission portion 21 is located in a more centered region of the cleaning device, and the support of the entire cleaning device is more balanced.

In an optional embodiment, the cleaning device further includes an auxiliary wheel, which is disposed on the recycling container 3 and configured to contact the surface to be cleaned. The auxiliary wheel is mainly used to support the region of the cleaning device where the recycling container 3 is disposed, so that when the recycling container 3 receives a great amount of trash, the auxiliary wheel is able to stably support the recycling container 3 to avoid an uneven distribution of a weight in the cleaning device affecting the operation of the cleaning device.

In an optional embodiment, the roller is located on a side of the guiding plate away from the transmission side 111, and/or, a cavity is disposed within the transmission portion 21, and the roller is at least partially disposed within the cavity. In this way, the space of the transmission portion is fully utilized, so as to make the cleaning device more compact.

In an optional embodiment, the cleaning device further includes a roller driving member connected to the roller. The roller driving member is at least partially located within the cavity. Exemplarily, the roller driving member is the motor.

In an optional embodiment, referring to FIGS. 15-16, the cleaning device further includes a roller brush member 8 disposed behind the cleaning aid member 2. The roller brush member 8 is configured to perform at least one of the following: cleaning the surface to be cleaned, cooperating with the cleaning component 1 in transmitting the trash, or scraping the trash on the cleaning component 1.

In an optional embodiment, the roller brush member 8 is at least partially in contact with the surface to be cleaned while the cleaning device is operating. As the result, the roller brush member 8 cleans the surface to be cleaned as it rolls.

In an optional embodiment, the roller brush member 8 is disposed between the cleaning aid member 2 and the recycling container 3. When the cleaning device is in operating, the first annular cleaning belt 11 is able to carry the trash on the surface to be cleaned under the friction as it rotates and to pick up and transmit the trash with the assistance of the cleaning aid member 2. When the first annular cleaning belt 11 transmits the trash to the end of the transmission slope 22 of the cleaning aid member 2, the trash is transmitted to the surface of the roller brush member 8, and the trash continues to be transmitted to the recycling container 3 under the rolling of the roller brush member 8.

In addition, when the roller brush member 8 is in contact with the surface of the first annular cleaning belt 11, the roller brush member 8 also scrapes the surface of the first annular cleaning belt 11 to scrape off the trash stuck to the surface of the first annular cleaning belt 11. The scraped trash falls onto the surface of the roller brush member 8 before being transmitted to the recycling container 3, or the scraped trash falls directly into the recycling container 3.

In an optional embodiment, the recycling container 3 includes the trash cavity 32 connecting the opening 31, and the roller brush member 8 is at least partially disposed within the trash cavity 32. In this way, the trash cavity 32 is able to better take up the trash falling from the surface of the roller brush member 8.

In an optional embodiment, a radius of the roller member 8 is the same as the radius of the first roller 12, which effectively reduces a production cost.

In an optional embodiment, the rotation direction of the roller brush member 8 is in a same direction as the rotation direction of the first annular cleaning belt 11 to scrape the trash on the cleaning component 1. Referring to FIG. 15, the surface of the roller brush member 8 is close to the transmission side 111 of the first annular cleaning belt 11, and of course, the surface of the roller brush member 8 contacts the transmission side 111 of the first annular cleaning belt 11. When the roller brush member 8 rotates in the same direction as the first annular cleaning belt 11, the surfaces of the roller brush member 8 and the transmission side 111 are running in the opposite directions, so that the roller brush member 8 is able to remove the trash on the first annular cleaning belt 11 to avoid the trash from sticking to the surface of the first annular cleaning belt 11.

In an optional embodiment, the rotation direction of the roller brush member 8 is in a direction opposite to the rotation direction of the first annular cleaning belt 11 to cooperate with the cleaning component 1 in transmitting the trash. Referring to FIG. 13, the surface of the roller brush member 8 is close to the transmission side 111 of the first annular cleaning belt 11, and of course, the surface of the roller brush member 8 may also contact the transmission side 111 of the first annular cleaning belt 11. When the roller brush member 8 rotates in the same direction as the first annular cleaning belt 11, the surfaces of the roller brush member 8 and the transmission side 111 are running in the same direction, so that the roller brush member 8 cooperates with the first annular cleaning belt 11 to grip and transmit the trash together. When the trash is transmitted on the surface of the roller brush member 8, the trash continues to be transmitted to the recycling container 3 under the rolling of the roller brush member 8.

In an optional embodiment, a diameter of the roller brush member 8 is the same as a diameter of the first roller 12, which is conducive to reducing the production cost.

In an optional embodiment, referring to FIG. 15, the cleaning aid member 2 includes a subordinate cleaning member 26. The subordinate cleaning member 26 includes a second annular cleaning belt 261, a third roller 262, and a fourth roller 263. The second annular cleaning belt 261 rotatably surrounds the third roller 262 and the fourth roller 263. The subordinate cleaning member 26 is configured to perform at least one of the following: cleaning the surface to be cleaned, or cooperating with the cleaning component 1 in transmitting the trash.

In an optional embodiment, a bottom of the second annular cleaning belt 261 is formed with a first plane 2611 for pressing against the surface to be cleaned. In this way, the second annular cleaning belt 261 cleans the surface to be cleaned when rotating.

In an optional embodiment, referring to FIG. 17, the third roller 262 and the fourth roller 263 cooperate to abut the second annular cleaning belt 261 against the surface to be cleaned to form the first plane 2611. As the result, the first plane 2611 has a greater area and a greater contact area with the surface to be cleaned, which is able to adequately clean the surface to be cleaned. In an optional embodiment, the third roller 262 abuts the second annular cleaning belt 261 against the surface to be cleaned to form the first plane 2611.

In an optional embodiment, a diameter of the fourth roller 263 is the same as the diameter of the first roller 12, and a diameter of the third roller 262 is the same as a diameter of the second roller 13, which effectively reduces the production cost.

In an optional embodiment, a side of the second annular cleaning belt 261 opposite to the transmission side 111 forms the transmission slope 22. Specifically, the transmission slope 22 is configured to cooperate with the first annular cleaning belt 11 to assist the first annular cleaning belt 11 in transmitting the trash. When the cleaning device is operating, the trash is held between the transmission side 111 and the transmission slope 22, and the first annular cleaning belt 11 transmits the trash to a preset position under the friction when rotating.

In an optional embodiment, the fourth roller 263 is disposed at an angle above the third roller 262, so that the second annular cleaning belt 261 forms the transmission slope 22.

In an optional embodiment, with reference to FIGS. 15-17, a highest point of the fourth roller 263 is located at an angle above a highest point of the third roller 262, so that the second annular cleaning belt 261 forms the transmission slope 22. Specifically, the bottoms of the third roller 262 and the fourth roller 263 are at the same level, but the highest point of the outer surface of the fourth roller 263 is higher than the third roller 262, so that the second annular cleaning belt 261 that surrounds the third roller 262 and the fourth roller 263 forms the inclined transmission slope 22.

In an optional embodiment, the fourth roller 263 is disposed behind the third roller 262, and the diameter of the fourth roller 263 is greater than the diameter of the third roller 262. The fourth roller 263 cooperates with the third roller 262 to abut against a lower portion of the inner surface 113 of the second annular cleaning belt 261 to make the bottom of the second annular cleaning belt 261 be formed with the first plane 2611 for pressing against the surface to be cleaned. The fourth roller 263 cooperates with the third roller 262 to abut against an upper side of the inner surface 113 of the second annular cleaning belt 261 to make the second annular cleaning belt 261 form the transmission slope 22. Thereby, the first plane 2611 serves to clean the surface to be cleaned, and the transmission slope 22 cooperates with the transmission side 111 of the first annular cleaning belt 11 to pick up and transmit the trash. In addition, the fourth roller 263 is located behind the third roller 262 and the diameter of the fourth roller 263 is greater than the diameter of the third roller 262. When the bottoms of the fourth roller 263 and the fourth roller 263 are located at the same level, the second annular cleaning belt 261 surrounding the fourth roller 263 and the third roller 262 also naturally forms the inclined transmission slope 22.

In an optional embodiment, the cleaning device further includes the recycling container 3 for collecting the trash. The recycling container 3 includes the opening 31 disposed behind the transmission slope 22 along the forward direction of the cleaning device. In this way, the cleaning device cleans the surface to be cleaned as it forwards, and the trash that is picked up and transmitted is transmitted along the transmission slope 22 into the recycling container 3. Thus, by disposing the recycling container 3, the trash transmitted is collected first, so as to facilitate the continuous operating of the cleaning device, and then the trash is dumped at one time when the trash is sufficiently great.

In an optional embodiment, with reference to FIGS. 15 and 18, the fourth roller 263 and the second roller 13 are spaced apart, so that there is a trash outlet between an end of the cleaning component 1 away from the surface to be cleaned and the end of the subordinate cleaning member 26 away from the surface to be cleaned. The trash outlet is connected to the opening 31 of the recycling container 3. The trash outlet is smaller than or equal to the opening in size to ensure that the trash enters the opening 31 after coming out of the trash outlet. As the fourth roller 263 is spaced apart from the second roller 13, an open space is formed between the end of the cleaning component 1 away from the surface to be cleaned and the end of the subordinate cleaning member 26 away from the surface to be cleaned. The open space is the outlet of the trash transmission. The trash falls through the trash outlet and enters the trash cavity 32 through the opening 31 of the recycling container 3. Optionally, the fourth roller 263 and the second roller 13 are spaced apart in such a position that the fourth roller 263 is disposed on a front bottom of the second roller 13.

In an optional embodiment, referring to FIGS. 15-18, the cleaning device further includes a third scraper 43. The third scraper 43 is disposed between the second annular cleaning belt 261 and the recycling container 3. The end of the third scraper 43 points toward the second annular cleaning belt 261. The third scraper 43 is configured to scrape the trash from the second annular cleaning belt 261 and/or for guide the trash to the opening 31 of the recycling container 3.

As the second annular cleaning belt 261 rotates when the cleaning device is operating, the end of the third scraper 43 is close to the surface of the second annular cleaning belt 261 or contacts the surface of the second annular cleaning belt. In this way, the trash on the surface of the second annular cleaning belt 261 is scraped off. As the third scraper 43 is disposed between the second annular cleaning belt 261 and the recycling container 3, the end of the third scraper 43 away from the second annular cleaning belt 261 is close to the opening 31 of the recycling container 3, so that when the trash is transmitted into the recycling container 3 by the second annular cleaning belt 261, the third scraper 43 plays a role of transmission connection to guide the trash to the recycling container 3. Of course, the third scraper 43 is configured both to scrape the trash off the surface of the second annular cleaning belt 261, and to guide the trash into the opening 31 of the recycling container 3.

In an optional embodiment, the cleaning device further includes a first scrape strip 71. The first scrape strip 71 is disposed behind the subordinate cleaning member 26. The first scrape strip 71 abuts against the second annular cleaning belt 261 and/or the surface to be cleaned for scraping the surface to be cleaned during the operation of the cleaning device. In this way, when the cleaning device forwards, the first scrape strip 71 scrapes the trash or the sewage from the surface to be cleaned toward the second annular cleaning belt 261, which carries the trash or the sewage away as the second annular cleaning belt 261 rotates.

In an optional embodiment, the cleaning device further includes a second scrape strip 72. The second scrape strip 72 is disposed in front of the subordinate cleaning member 26. The second scrape strip 72 abuts against the second annular cleaning belt 261 and/or the surface to be cleaned for scraping the surface to be cleaned during the operation of the cleaning device. In this way, when the cleaning device is retreats, the second scrape strip 72 scrapes the trash or the sewage on the surface to be cleaned towards the second annular cleaning belt 261, and the second annular cleaning belt 261 carries away the trash or the sewage as it rotates.

In an optional embodiment, by placing the first scrape strip 71 against the second annular cleaning belt 261, there is no gap or a very small gap between the first scrape strip 71 and the second annular cleaning belt 261, so as to minimize the gap resulting in residual water. Similarly, by placing the second scrape strip 72 against the second annular cleaning belt 261, there is no gap or a very small gap between the second scrape strip 72 and the second annular cleaning belt 261, so as to minimize the gap resulting in the residual water.

In an optional embodiment, the first scrape strip 71 and the second scrape strip 72 are paired, and when the cleaning device cleans forward, the first scrape strip 71 scrapes and cleans the cleaning surface to be cleaned. When the cleaning device cleans backward, the second scrape strip 72 scrapes and cleans the cleaning surface. The first scrape strip 71 and the second scrape strip 72 cooperate with each other, which not only makes the operation more convenient, but also greatly improves the cleaning effect of the surface to be cleaned.

In an optional embodiment, with reference to FIGS. 3A-4, and to FIG. 10, a portion of the first annular cleaning belt 11 close to the surface to be cleaned is formed with a guiding surface 116 connected to the transmission side 111. The guiding surface 116 extends obliquely from a portion of the cleaning aid member 2 close to the surface to be cleaned towards an upper front portion of the cleaning device along a direction gradually away from the cleaning aid member and the surface to be cleaned. The guiding surface 116 is configured to guide the trash on the surface to be cleaned to the cleaning aid member 2 or an operation region of the cleaning aid member 2. Specifically, the guiding surface 116 is the first to contact the trash during the forward of the cleaning device, so as to facilitate the entry of the trash with great volume to between the guiding surface 116 and the surface to be cleaned. The guiding surface 116 extends obliquely downwards to facilitate a better transmission of the trash to the cleaning aid member 2 or the operation region of the cleaning aid member 2.

In an optional embodiment, a slope of the guiding surface 116 is greater than or equal to 20 degrees and less than or equal to 70 degrees.

In an optional embodiment, the slope of the guiding surface 116 is greater than or equal to 30 degrees and less than or equal to 50 degrees.

Optionally, the slope of the guiding surface 116 refers to a slope of a line connecting the highest point to the lowest point of the guiding surface 116.

In an optional embodiment, the height of a highest point of the guiding surface 116 is greater than or equal to 10 mm and less than or equal to 40 mm, for example, 10 mm, 20 mm or 40 mm.

In an optional embodiment, the height of the highest point of the guiding surface 116 is also set to be greater than or equal to 18 mm, less than or equal to 26 mm, for example, 18 mm, 20 mm or 25 mm.

Optionally, the height of the highest point of the guiding surface 116 refers to a spacing between the highest point and the lowest point of the guiding surface 116.

In an optional embodiment, the highest point of the guiding surface 116 and the surface to be cleaned form an inlet for guiding the trash to enter, and by setting the height of the guiding surface 116, the trash of a corresponding height is imported, so as to clean the trash.

In an optional embodiment, the ratio of the height of the highest point of the guiding surface 116 to the length of the opening 31 of the recycling container 3 along the extension direction of the transmission slope is greater than or equal to 0.7 and less than or equal to 1.4.

In an optional embodiment, the ratio of the height of the highest point of the guiding surface 116 to the length of the opening 31 of the recycling container 3 along the extension direction of the transmission slope is greater than or equal to 0.8 and less than or equal to 1.2.

As the trash enters through the guiding surface 116 and ultimately enters the recycling container 3 through the opening 31, by setting the ratio of the height of the highest point of the guiding surface 116 to the opening close to 1, the incoming trash is made to be able to later enter the recycling container 3 through the opening and effectively reduce a redundancy of the respective size, so as to reduce a design difficulty and save volume.

By limiting the slope and the height of the guiding surface 116, the cleaning device is made to adapt to more types of trash and improve the ability of the cleaning device to pick up and transmit each type of trash, thereby improving the cleaning effect.

In an optional embodiment, the first roller 12 abuts against the first annular cleaning belt 11, so that a portion of the first annular cleaning belt 11 facing the forward direction of the cleaning device and disposed opposite to the surface to be cleaned forms the guiding surface 116.

In an optional embodiment, when the cleaning component 1 automatically adjusts the distance from the cleaning component 1 to the surface to be cleaned based on the size of the trash, the cleaning component 1 is lifted as a whole, i.e., the transmission side 111 and the transmission slope 22 remains parallel with a shorter distance, or the cleaning component 1 is lifted as a whole, i.e. the angle between the transmission side 111 and the transmission slope 22 remains unchanged. In this way, the cleaning component 1 adjusts the gap between the transmission side 111 and the transmission slope 22 without rotating.

It is to be noted that by setting the gap between the bottom of the cleaning component 1 and the surface to be cleaned to be adjustable, the gap is able to be enlarged or narrowed, so that the gap is adapted to the trash of different volumes and sizes, and the cleaning component 1 is capable of transmitting both trash with small volume and great volume to between the first annular cleaning belt 11 and the cleaning aid member 2, which effectively ensures the cleaning effect of the cleaning device in cleaning the trash on the surface to be cleaned.

In an optional embodiment, the cleaning component 1 is rotatably disposed relative to the cleaning aid member 2 to enable the cleaning component 1 to adjust the gap between the cleaning component 1 and the surface to be cleaned and/or a gap between the cleaning component and the cleaning aid member 2.

In an optional embodiment, the rotation of the cleaning component 1 relative to the cleaning aid member 2 allows for a simultaneous adjustment of the gap between the cleaning component 1 and the surface to be cleaned and the gap between the cleaning component 1 and the transmission slope 22.

In an optional embodiment, the rotation of the cleaning component 1 relative to the cleaning aid member 2 adjusts the gap between the cleaning component 1 and the surface to be cleaned.

In an optional embodiment, the cleaning aid member 2 includes the transmission slope 22 disposed opposite to the transmission side 111, and the rotation of the cleaning component 1 relative to the cleaning aid member 2 adjusts the gap between the cleaning component 1 and the transmission slope 22. Thereby, the rotatable setting of the cleaning component 1 allows the cleaning device to remove the trash with different sizes and volumes.

In an optional embodiment, the first roller 12 is configured to press the local portion of the first annular cleaning belt 11 against the surface to be cleaned, and the second roller 13 is located at an angle above the first roller 12. A rotation axis of the cleaning component 1 rotatably disposed relative to the cleaning aid member 2 is co-linear with an axis of the second roller 13. In this way, a general structure of the cleaning device is more compact, the volume of the cleaning device is reduced as much as possible. It is more convenient for the user to operate the cleaning device, and a storage space is saved when the cleaning device is not in use.

In an optional embodiment, the cleaning component 1 includes a rotation member 17. The cleaning component 1 is rotationally disposed on the cleaning aid member 2 through the rotation member 17.

In an optional embodiment, the cleaning component 1 is rotationally disposed on the side stop portion 24 through the rotation member 17. Optionally, the side stop portion 24 protrudes and extends at an angle above the transmission slope, so that the rotation member 17 is disposed on the side stop portion 24.

In an optional embodiment, the cleaning component 1 is also rotationally disposed in the recycling container 3 through the rotation member 17. In an optional embodiment, referring to FIGS. 20-21, the cleaning component 1 is also rotatably disposed on the chassis 5 through the rotation member 17.

Optionally, the cleaning component 1 is rotatably disposed on the cleaning aid member 2, the chassis 5, or the recycling container 3 through the rotation component 17, that is, the cleaning component 1 uses the rotation component 17 as a swing axis to form a swing arm structure, so that other parts (such as the first roller 12, a portion of the first annular cleaning belt 11) of the cleaning component 1 swing relative to the cleaning aid component 2, thereby adjusting the gap between the cleaning component 1 and the surface to be cleaned, as well as the gap between the cleaning component 1 and the transmission slope 22.

In an optional embodiment, the rotation axis of the cleaning component 1 rotatably disposed relative to the cleaning aid component 2 is parallel to the axis of the second roller 13, that is, the rotation axis of the rotation member 17 is parallel to the axis of the second roller 13.

Optionally, by disposing the rotation axis of the cleaning component 1 that is rotatably disposed relative to the cleaning aid component 2 parallel to the axis of the second roller 13, a force direction of the cleaning component 1 (e.g., the friction force between the cleaning component 1 and the surface to be cleaned, etc.) matches a movable direction of the cleaning component 1, so that the stability of the whole cleaning component 1 is improved. Moreover, when the cleaning component 1 rotates relative to the cleaning aid component 2, cantilevers of parts of the first roller 12 is the same with each other, so as to achieve the better cleaning effect for the surface to be cleaned.

In an optional embodiment, the rotation axis of the cleaning component 1 rotatably disposed relative to the cleaning aid member 2 is co-linear with the axis of the second roller 13.

Optionally, the rotational axis of the cleaning component 1 rotatably disposed relative to the cleaning aid member 2 is disposed on a side of the second roller 13 away from or close to the first roller 12.

In an optional embodiment, the rotation member 17 is disposed at ends of the second roller 13 in the axial direction of the second roller 13. In an optional embodiment, referring to FIGS. 20-21, the rotation member 17 is a convex shaft 171 disposed at two ends of the second roller 13, and the cleaning aid member 2, the side stop portion, the recycling container 3, or the chassis 5 is provided with a perforation 172 for the threading of the convex shaft 171. In this way, the rotation of the cleaning component 1 is realized.

Optionally, by making the rotation axis of the cleaning component 1 rotatably disposed relative to the cleaning aid member 2 colinear with the axis of the second roller 13, as the second roller 13 is a roller structure and the axis of the second roller 13 is colinear with the rotation axis (the swing axis) of the cleaning component 1 rotatably disposed relative to the cleaning aid member 2, so that in the process of the cleaning component 1 swinging (rotating) relative to the cleaning aid member 2, the second roller 13 is not affected by the swinging. Therefore, the end of the first scraper 41 is directed toward the second roller 13, so that the gap between the first scraper 41 and the second roller 13 is constant and is not affected by the swinging (rotation) of the cleaning component 1 relative to the cleaning aid member 2, and accordingly, the first annular cleaning belt 11 located in the middle is stably squeezed, and the scraping ability is improved.

In an optional embodiment, the cleaning component 1 includes a support 141. The first roller 12 and the second roller 13 are both rotatably disposed on the support 141 and are spaced apart from each other.

As a result, the trash is unlikely to be hidden or stuck in the gap, and the whole structure is made to be more compact and stable.

In an optional embodiment, as the cleaning component 1 is rotationally disposed relative to the cleaning aid member 2, the end of the first scraper 41 points to the rotation axis of the cleaning component 1 rotationally disposed relative to the cleaning auxiliary 2. As the result, the cleaning component 1 rotates around the rotation axis while rotating, the first scraper 41 interferes minimally with the cleaning component 1 while the cleaning component 1 rotates, and the first scraper 41 is able to realize the scraper function without hindering the rotation of the cleaning component 1 when picking up the trash.

In an optional embodiment, the cleaning component 1 has the lowest point in a direction perpendicular to the surface to be cleaned, and the lowest point of the cleaning device 1 has a pre-pressure on the surface to be cleaned when the cleaning device 1 is placed on the surface to be cleaned.

Compared to the existing roller brush scrubbers (which are incapable of cleaning the trash with great size and is likely to be stuck by the trash with great size), there is no need for sweeping the floor before washing the floor. The sweeping and washing are performed at the same time, so as to greatly improve the convenience of cleaning. The first cleaning component 1 is inclined as a whole, and forms the inclined transmission side 111 and the transmission slope 22. Compared to the existing roller brush scrubbers, the transmission height of the trash is effectively increased, making it possible for the recycling container 3 to have a better depth, which increases the size of the trash cavity 32 of the recycling container 3, which is more conducive to cleaning the trash with great volume, and thus increases the cleaning effect and the cleaning power.

The battery member has a first electrical connection port, and the rotation member 17 is provided with a second electrical connection port. A battery member 52 supplies power to the driving member through cooperation of the first electrical connection port and the second connection port. As the second electrical connection port is disposed on the rotation member 17, wires connecting the first electrical connection port and the second electrical connection port are not easily affected when the cleaning component 1 rotates, thereby reducing a possibility for the wires to be pulled or tangled.

In an optional embodiment, the driving component is the driving motor. The driving motor is connected to the first roller 12 for driving the first roller 12 to rotate and thereby driving the first annular cleaning belt 11 to rotate.

In addition, the first roller 12 is disposed with the driving motor, the second roller 13 is not disposed with the driving motor, and the weight of the first roller 12 is greater than the weight of the second roller 13. When the cleaning device performs the cleaning operation on a horizontal surface, such as the ground, a center of gravity of the cleaning device is lowered, and the cleaning device is more stable during the cleaning operation.
