[0046] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0047] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0048] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0049] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0050] The specific embodiments of this disclosure are described below with reference to the accompanying drawings.

[0051] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0052] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0053] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0054] This disclosure provides a cleaning system including a cleaning device and a base station. The cleaning device can be a handheld cleaning device, such as a handheld washer, handheld vacuum cleaner, handheld floor scrubber, or other handheld cleaning devices well-known to those skilled in the art. It can also be a robotic vacuum cleaner, robotic mop, or a robotic vacuum and mop combo, or other self-propelled cleaning devices. The base station is configured to hold the cleaning device; for example, after cleaning a work surface, the user can place the cleaning device on the base station, thus ensuring stable placement. The end face of the base station is configured to conform to the bottom face of the cleaning device, allowing the base station to better support the cleaning device.

[0055] The cleaning equipment includes a floor brush assembly, which comprises a floor brush housing and a roller controlled by a drive unit. During the cleaning process, the roller contacts the work surface, and the drive unit drives the roller to rotate, thereby cleaning the work surface.

[0056] The direction of rotation of the roller can be changed. Specifically, the roller rotates relative to the brush housing in a first direction during a first duration; and rotates relative to the brush housing in a second direction during a second duration.

[0057] In existing cleaning equipment, rollers rotate in the same direction for cleaning. Over prolonged use, the roller bristles gradually adhere to the cleaning body, reducing the interference fit between the roller and the work surface. This results in decreased cleaning effectiveness and a significantly negative impact on the user experience. Prolonged rotation in a single direction causes the bristles to collapse and press tightly against the roller, reducing their absorbency and leading to a thicker water film on the roller. Furthermore, most rollers on the market are used with a squeegee to remove trapped wastewater and debris. The pressure from the squeegee deforms the roller bristles, shortening their lifespan and exacerbating the water film problem.

[0058] The cleaning system disclosed herein causes the roller to rotate relative to the brush housing in a first direction about its own axis for a first duration, and then rotates relative to the brush housing in a second direction about its own axis for a second duration. By changing the direction of rotation of the roller, the bristles of the roller oscillate in different directions at different durations, thus avoiding the problem of bristle collapse caused by the roller rotating in a single direction for a long time. This allows the cleaning effect of the cleaning equipment to remain in good condition for a longer period of time, and further extends the service life of the roller.

[0059] To facilitate better understanding, the following is illustrated with the accompanying diagrams. Figures 1 to 12 This will be explained in detail in terms of the specific structure and working principle of the cleaning system disclosed herein.

[0060] Example 1

[0061] This embodiment provides a cleaning system, referencing... Figure 1 The cleaning system includes cleaning equipment 1 and base station 2.

[0062] Cleaning equipment 1 includes a floor brush assembly 11 and a body assembly 15. (Continue to refer to...) Figure 1 The body assembly 15 is rotatably connected to the floor brush assembly 11, which allows the user to dynamically adjust the connection angle between the body assembly 15 and the floor brush assembly 11 according to the user's needs, making it easier for the user to carry out cleaning work.

[0063] For specific references Figure 2 The fuselage assembly 15 includes a fuselage housing 16 and a switch 3 disposed on the fuselage housing 16. (See reference) Figure 3 and Figure 6 The floor brush assembly 11 includes a floor brush housing 12 and a roller 121 controlled by a drive unit 14. The roller 121 is configured to contact a work surface, such as a floor, to perform cleaning work. (Reference) Figure 10 and Figure 11 The output end of the drive unit 14 is rotatably connected to at least one end of the roller 121. In this way, the drive unit 14 can drive the roller 121 to rotate.

[0064] Base station 2 is configured to house cleaning device 1. To ensure stable placement of cleaning device 1, the base end face of base station 2 is configured to fit the bottom surface of cleaning device 1. Base station 2 can charge cleaning device 1, and cleaning device 1 can also perform self-cleaning operations on base station 2. This type of base station 2 is common knowledge to those skilled in the art and will not be described in detail here.

[0065] During the cleaning process of the cleaning device 1, as the roller 121 contacts the working surface and rotates under the control of the drive unit 14, the contact area between the roller 121 and the working surface gradually wears down. Specifically, the external structure of the roller 121 gradually comes into contact with the body of the roller 121, causing the interference fit between the roller 121 and the working surface to gradually decrease, resulting in a decrease in the cleaning effect of the cleaning device 1. This can be avoided by changing the rotation direction of the roller 121. Reversing the rotation causes the bristles of the roller 121 to swing in the opposite direction under the action of centrifugal force, which helps maintain the stability of the external structure of the roller 121, thereby protecting the roller 121.

[0066] The cleaning system disclosed herein controls the roller 121 to rotate about its own axis in a first direction during a first duration, and controls the roller 121 to rotate about its own axis in a second direction during a second duration. It should be noted that the first direction and the second direction in this disclosure do not refer to the rotation direction of the drive unit 14, but rather to the rotation direction of the roller 121 relative to the floor brush housing 12 about its own axis.

[0067] In one embodiment of this disclosure, using roller 121 as a reference, after roller 121 is installed on the floor brush housing 12, the rotation direction of roller 121 can be switched within a first time period and a second time period by controlling roller 121 to rotate clockwise or counterclockwise. The first direction can be, for example, clockwise rotation and the second direction can be counterclockwise rotation. Alternatively, the first direction can be counterclockwise rotation and the second direction can be clockwise rotation. In this embodiment, the drive unit 14 drives roller 121 to rotate clockwise and counterclockwise.

[0068] In another embodiment of this disclosure, the rotation of the roller 121 in two directions can also be achieved by switching the mounting direction of the roller 121 on the brush housing 12. For example, during a first duration, the drive unit 14 controls the roller 121 to rotate around its own axis in a first direction, and the bristles of the roller 121 swing in the first direction under the action of centrifugal force. During a second duration, the roller 121 is removed and installed in reverse on the brush housing 12. At this time, although the drive unit 14 still maintains rotation in the same direction, relative to the first direction during the first duration, the roller 121 will rotate around its own axis in the second direction, and the bristles of the roller 121 will swing in the second direction under the action of centrifugal force.

[0069] The two embodiments described above are described in detail below.

[0070] In some embodiments of this disclosure, the cleaning system further includes a control unit. The control unit is configured to control the roller 121 to rotate in a first direction for a first duration and to control the roller 121 to rotate in a second direction for a second duration.

[0071] In practical use, the control unit can communicate with the drive unit 14, and the control unit is configured to send control signals to the drive unit 14, thereby controlling the drive unit 14 to switch the rotation direction of the roller 121.

[0072] In some embodiments of this disclosure, the first duration is the duration during which the cleaning device 1 performs the working surface cleaning step, and the second duration is the duration during which the cleaning device 1 performs the next working surface cleaning step.

[0073] Specifically, during the first time period, the cleaning device 1 performs the current cleaning operation on the work surface. During this time, the roller 121 rotates continuously in the first direction, for example, clockwise, to clean the work surface. After the cleaning device 1 finishes the current cleaning operation, the user turns off the cleaning device 1.

[0074] When the user restarts the cleaning device 1 to perform the next cleaning operation, the control unit outputs a control signal to the drive unit 14, causing the roller 121 to change its rotation direction under the control of the drive unit 14. The cleaning operation lasts for a second duration. During this second duration, the roller 121 rotates in the second direction for cleaning; for example, the control unit controls the roller 121 to rotate counterclockwise to clean the work surface.

[0075] Because the first direction is opposite to the second direction, the rotation direction of the roller 121 changes when the cleaning device 1 performs different cleaning operations. This avoids damage to the structure of the roller 121 caused by long-term rotation in a single direction, thus protecting the roller 121 and ensuring that the interference fit between the roller 121 and the working surface remains within a relatively stable range. This effectively improves the cleaning effect and service life of the roller 121.

[0076] Furthermore, during different cleaning operations, the control unit will automatically switch the rotation direction of the roller 121, which can also prevent situations where the user forgets to switch the rotation direction of the roller 121.

[0077] In another embodiment of this disclosure, the first duration and the second duration are different durations within the current cleaning step of the cleaning device 1. Specifically, the first duration and the second duration are different time periods when the cleaning device 1 performs the same cleaning operation.

[0078] In actual use, when the user is cleaning the working surface using the cleaning equipment 1, the control unit can switch the rotation direction of the roller 121 at any time by sending a control signal to the drive unit 14.

[0079] When cleaning equipment 1 is started to clean the working surface, the current rotation direction of roller 121 is defined as the first direction. Correspondingly, the cleaning time in the first direction is the first duration. When the control unit outputs a control signal, the rotation direction of roller 121 changes. This current rotation direction of roller 121 is recorded as the second direction, and the corresponding rotation time in the second direction is the second duration.

[0080] It is worth noting that both the first and second durations refer to the time period during which the cleaning device 1 performs its current cleaning operation. Even when the roller 121 rotates in the second direction during the second duration, the control unit can still change the rotation direction of the roller 121. As long as the current cleaning operation of the cleaning device 1 has not ended, the rotation direction of the roller 121 can be switched at any time.

[0081] In some embodiments of this disclosure, the control unit is configured to control the drive unit 14 to switch the rotation direction of the roller 121 based on a preset time interval. Specifically, the time interval can be a preset time period within the cleaning system or a time period set by the user according to actual usage needs.

[0082] The rotation direction of roller 121 is changed at preset time intervals, for example, every 10 seconds. This keeps the rotation time of roller 121 balanced in the first and second directions, preventing the rotation time in one direction from being significantly longer than in the other. By evenly distributing the rotation time of roller 121 in different directions, its service life can be extended to the maximum extent.

[0083] In some embodiments of this disclosure, the cleaning device 1 further includes a toggle switch 3. (See reference...) Figure 2 The top of the body assembly 15 is designed as a handle structure for easy gripping by the user. The switch 3 can be located on the body housing 16 in the area near the handle structure, and further, the switch 3 is located in a position that is easy for the user to control.

[0084] The switch 3 is communicatively connected to the control unit. The control unit is configured to send a control signal to the drive unit 14 based on the switching signal input from the switch 3, so as to switch the rotation direction of the roller 121.

[0085] In detail, during the use of cleaning equipment 1, the user can change the rotation direction of the roller 121 around its own axis at any time by clicking the switch 3. This allows the user to change the rotation direction of the roller 121 according to the actual environment or their own needs. For example, when the user observes that the work surface is not clean or has residual water stains, they can control the roller 121 to rotate in the opposite direction using the switch 3, thereby cleaning the work surface. This improves the user experience and ensures the cleaning effect.

[0086] In some embodiments of this disclosure, the first duration is the duration during which the cleaning device 1 performs the working surface cleaning step, and the second duration is the duration during which the cleaning device 1 performs the self-cleaning step on the base station 2.

[0087] In practical use, the working time of cleaning device 1 during surface cleaning is defined as the first duration. During the first duration, roller 121 rotates in the first direction; for example, when cleaning the work surface, roller 121 always rotates clockwise. After cleaning, the user can place cleaning device 1 on base station 2 and activate its self-cleaning mode. The working time of the self-cleaning mode is defined as the second duration, and the rotation direction of roller 121 during self-cleaning can be referred to as the second direction, such as counterclockwise. The method of self-cleaning of cleaning device 1 on base station 2 is well known to those skilled in the art and will not be described in detail here. When the work surface needs to be cleaned, the cleaning device is removed from base station 2, and roller 121 continues to rotate in the first direction to clean the work surface.

[0088] When the cleaning equipment 1 performs different cleaning tasks, the rotation direction of the roller 121 is changed by the control unit to protect the roller 121 and extend its cleaning effect and service life.

[0089] In a specific embodiment of this disclosure, when the cleaning device 1 is placed on the base station 2 and performs the self-cleaning operation, the control unit can also switch the rotation direction of the roller 121 during the current self-cleaning operation period. The specific principle and structure have been described in detail above and will not be repeated here.

[0090] In the above embodiments, by switching the rotation direction of the roller 121 through the control unit, the external structure of the roller 121 is protected, and the interference fit between the roller 121 and the working surface and the cleaning effect of the roller 121 are maintained in a long-term stable state. Based on the above disclosure, those skilled in the art can select and design specific design schemes according to actual needs, and no further restrictions are imposed here.

[0091] In some embodiments of this disclosure, reference is made to Figure 4The roller 121 is rotatably connected to the floor brush housing 12, and the rotation axis of the roller 121 is constructed to be parallel to the working surface.

[0092] refer to Figure 8 In the view orientation, the direction of clockwise rotation of roller 121 is defined as the first direction. That is, rotation of roller 121 along the first direction can be understood as roller 121 rotating clockwise at this time. (Continue to refer to...) Figure 9 The direction of counterclockwise rotation of the roller 121 is defined as the second direction. Of course, for those skilled in the art, the first direction can also be counterclockwise rotation and the second direction can be clockwise rotation. This is only to more clearly describe the rotation direction of the cleaning device 1 below, and is not intended to limit the rotation direction of the first and second directions.

[0093] In some embodiments of this disclosure, reference is made to Figure 7 The floor brush housing 12 is also provided with a scraper 122. The scraper 122 abuts against the roller 121 in the floor brush assembly 11 and is configured to scrape off the dirt on the roller 121, which is a mixture of dirty water and foreign matter.

[0094] In actual use, the roller 121 remains rotating throughout the cleaning process of the cleaning equipment 1. The scraper 122 scrapes wastewater and foreign objects off the surface of the roller 121 by pressing it. The floor brush housing 12 is also equipped with a suction port 123. (Continue to refer to...) Figure 7 The suction port 123 is located in the area below the scraper 122. The dirt scraped off by the roller 121 will fall towards the suction port 123 and be sucked in by the suction port 123.

[0095] Furthermore, the outer surface of the roller 121 is also covered with bristles. When the roller 121 is used for cleaning in a clockwise or counterclockwise direction for an extended period, the bristles are pressed against the roller 121 by the continuous pressure of the scraper 122. As the bristles gradually come into close contact with the roller 121 body, the water adhering to the roller 121 can only remain on the surface of the roller 121, thus forming a water film on the outer surface of the roller 121. Therefore, when the roller 121 is used for cleaning, watermarks will be left on the working surface, affecting the cleaning effect.

[0096] To avoid the above situation, the rotation direction of the roller 121 is changed, and the bristles are scraped back by the scraper 122. This maintains an appropriate distance between the bristles and the roller 121 body, thus controlling the water absorption and cleaning effect of the roller 121.

[0097] refer to Figure 9The roller 121 rotates counterclockwise. At this time, the dirt attached to the roller 121 is scraped off by the scraper 122, and the scraped dirt will fall below the scraper 122. In this way, the suction port 123 can suck away the dirt and keep the working environment of the roller 121 clean.

[0098] In one specific embodiment of this disclosure, reference is made to Figure 8 When the roller 121 rotates clockwise, the scraper 122 scrapes the dirt on the roller 121 to the area above the scraper 122, where it cannot be sucked away by the suction port 123. Therefore, a notch 124 is required so that the dirt can flow through the notch 124 from the area above the scraper 122 to the area where the suction port 123 is located, and be sucked away by the suction port 123.

[0099] In one specific embodiment of this disclosure, reference is made to Figure 12 A notch 124 is provided on the scraper 122. In this way, dirt located in the area above the scraper 122 can flow through the notch 124 to the area below the scraper 122 and be sucked away by the suction port 123.

[0100] In some embodiments of this disclosure, reference continues to be made to Figure 12 The notch 124 is located in the area between the scraper 122 and the roller 121. Specifically, the end of the scraper 122 that contacts the roller 121 has a serrated shape with a flange. The flange portion can scrape off the dirt on the roller 121, and the dirt can flow along the gap between two adjacent flanges to the suction port 123, so that the suction port 123 can suck away the dirt.

[0101] In some embodiments of this disclosure, a notch 124 is provided in the area between the scraper 122 and the floor brush housing 12. Dirt located in the area above the scraper 122 can flow through the notch 124 to the area below the scraper 122 and be sucked away by the suction port 123.

[0102] The scraper 122 disclosed herein can be strip-shaped or cylindrical, etc. As long as it can achieve the following: after the scraper 122 scrapes the dirt on the roller 121, the dirt in the space above the scraper 122 can flow into the space below the scraper 122 and be sucked away by the suction port 123, no further limitations are imposed here.

[0103] In one embodiment of this disclosure, the roller 121 is switchably mounted on the floor brush housing 12. (See reference...) Figure 6 The floor brush housing 12 has two opposing support arms, and the opposite ends of the roller 121 are rotatably connected to the two support arms, thereby allowing the roller 121 to rotate relative to the floor brush housing 12. (Reference) Figure 11One of the support arms of the floor brush housing 12 is equipped with a drive unit 14. The output end of the drive unit 14 is engaged with one end of the roller 121, and the other end is rotatably connected to another support arm via a rotating component. The structures at both ends of the roller 121 can be identical, so that either end of the roller 121 can be rotatably connected to any support arm, thereby changing the installation direction of the roller 121.

[0104] Specifically, refer to Figure 4 Take any two points on the roller 121 and denote them as points A and B. The two opposite ends of the roller 121 are respectively denoteed as the first end and the second end, and the first end of the roller 121 is the end of the roller 121 that is away from points A and B. At this time, the first end of the roller 121 is rotatably connected to the output end of the drive unit 14, and the second end of the roller 121 is rotatably connected to the other arm.

[0105] In this embodiment, the roller 121 rotates counterclockwise. (See reference) Figure 4 In the view direction, when the roller 121 rotates counterclockwise, point B on the roller 121 passes the scraper 122 first, and then point A passes the scraper 122. This can be understood as the roller 121 rotating in the first direction, causing the scraper 122 to scrape past point B first, and then past point A.

[0106] Continue to refer to Figure 4 The user can remove roller 121 from the brush housing 12 and reverse its installation direction; that is, install the second end of roller 121 on the output end of drive unit 14 and install the first end of roller 121 on the other arm. The installation position and rotation direction of drive unit 14 remain unchanged, still rotating counterclockwise. (Reference) Figure 5 Because the direction of the roller 121 has been reversed, when the roller 121 rotates counterclockwise, point A on the roller 121 passes through the scraper 122 first, and then point B passes through the scraper 122.

[0107] In this embodiment, the rotation direction of the drive unit 14 remains unchanged. However, the rotation direction of the roller 121 relative to the brush housing 12 changes. This can be understood as the roller 121 rotating in a second direction, at which point the scraper 122 first scrapes past point A and then past point B.

[0108] In the above embodiment, the user manually reverses the direction of the roller 121. Of course, the installation direction of the roller 121 can be reversed by an automated control device, which can be installed on the base station 2 or other locations, thereby enabling the roller 121 to switch between two directions.

[0109] In this embodiment, during the first duration, the roller 121 can be controlled to rotate in the first direction; during the second duration, the installation direction of the roller 121 is reversed so that the roller 121 can rotate in the second direction. The first duration and the second duration can be the duration of the working surface cleaning step and the duration of the self-cleaning step, respectively, and can be the same as in Embodiment 1, which will not be described in detail here.

[0110] Example 2

[0111] Embodiments of this disclosure also provide a cleaning device 1. The cleaning device 1 includes a floor brush assembly 11, which includes a floor brush housing 12 and a roller 121 controlled by a control unit.

[0112] The roller 121 is configured to clean the work surface, and during a first duration, the roller 121 rotates relative to the brush housing 12 in a first direction, and during a second duration, it rotates relative to the brush housing 12 in a second direction.

[0113] The specific structure and working principle of cleaning equipment 1 have been explained in detail above and will not be repeated here.

[0114] Example 3

[0115] This disclosure also provides a control method for a cleaning system. This control method is used to control the aforementioned cleaning system. The specific structure and principle of the cleaning system have been described in detail above and will not be repeated here. The specific steps and effects of the control method for the cleaning system of this disclosure are described in detail below with reference to a specific embodiment.

[0116] The cleaning device 1 in the cleaning system disclosed herein has at least two different cleaning operation modes. These are a ground cleaning mode for cleaning the work surface to be cleaned, and a self-cleaning mode when the user places the cleaning device 1 on the base station 2 and activates the self-cleaning function.

[0117] The control method of the cleaning system disclosed herein includes the following steps: during a first duration, the roller 121 rotates relative to the floor brush housing in a first direction; during a second duration, the roller 121 rotates relative to the floor brush housing in a second direction.

[0118] In one embodiment of this disclosure, the roller 121 inside the cleaning device 1 is configured, under the control of the control unit, to rotate along a first direction and a second direction, respectively, for a first duration and a second duration. In one embodiment of this disclosure, the roller 121 can be switched between two different rotation directions by changing its installation direction.

[0119] The first duration and the second duration can be the duration of different ground cleaning modes, or different durations of the same ground cleaning mode, or the duration of the ground cleaning mode and the self-cleaning mode, respectively. The specific durations can be the same as in Embodiment 1, and will not be described in detail here.

[0120] The technical solution adopted by this invention will be described below in conjunction with specific application scenarios to aid understanding. In the following application scenario, the handheld cleaning device 11 is a handheld floor scrubber as an example for further description.

[0121] Application Scenario 1

[0122] When the user holds or controls the cleaning device 1 to perform cleaning work on the work surface, the drive unit 14 inside the cleaning device 1 drives the roller 121 to rotate in a first direction to clean the work surface.

[0123] After a preset time, the control unit sends a control signal to the drive unit 14, which then changes the rotation direction of the roller 121, causing the roller 121 to rotate in the second direction to clean the working surface.

[0124] The first direction and the second direction are two opposite directions. By controlling the rotation of the roller 121 in different directions, it can be ensured that the bristles on the roller 121 are in a fluffy state and will not be pressed tightly against the body of the roller 121 in one direction. This ensures that the interference between the roller 121 and the working surface remains in a stable state.

[0125] Application Scenario 2

[0126] When the user holds or controls the cleaning device 1 to perform cleaning work on the work surface, the drive unit 14 inside the cleaning device 1 drives the roller 121 to rotate in a first direction to clean the work surface.

[0127] When a user is cleaning the work surface with the handheld cleaning device 1, if the user finds that a certain position on the work surface is still dirty or has water stains after cleaning, the user can press the switch 3. After receiving the switching signal input by the switch 3, the control unit controls the roller 121 to switch the rotation direction. Even if the roller 121 rotates in the second direction, it can continue to clean the dirty or water stains on the work surface.

[0128] After the roller 121 changes direction, the bristles on the roller 121 will also swing in the other direction, which makes the bristles pressed on the roller 121 in a relatively fluffy state, improving the water absorption of the bristles and ensuring the cleaning effect of the cleaning device 1.

[0129] Application Scenario 3

[0130] When the user holds or controls the cleaning device 1 to perform cleaning work on the work surface, the drive unit 14 inside the cleaning device 1 drives the roller 121 to rotate in a first direction to clean the work surface.

[0131] After the working surface is cleaned, the user can place the cleaning device 1 on the base station 2. When the user presses the self-cleaning button, the clean water tank in the cleaning device 1 will supply water to the roller 121, and the roller 121 will rotate in the second direction to perform self-cleaning. When the user needs to use the cleaning device 1 to continue cleaning the working surface, the control unit will control the roller 121 to rotate in the first direction to clean the working surface.
