In this document, "first", "second", and the like are used only for distinguishing one from another, and do not indicate the degree and order of importance, the premise that each other exists, and the like.

In this context, "equal", "same", etc. are not strictly mathematical and/or geometric limitations, but also include tolerances as would be understood by a person skilled in the art and allowed for manufacturing or use, etc.

The present disclosure provides a cleaning system including a cleaning apparatus and a base station. The cleaning appliance may be a hand-held cleaning appliance, such as a hand-held washer, hand-held vacuum cleaner, hand-held floor scrubber, or the like, as is known to those skilled in the art. The cleaning robot can also be self-moving cleaning equipment such as a sweeping robot, a mopping robot, a sweeping and mopping integrated robot and the like. The base station is configured for placing the cleaning device, for example, after the cleaning device has cleaned the work surface, the user can place it on the base station, which enables the cleaning device to be placed stably. The end face of the base station is configured in a shape adapted to the bottom surface of the cleaning device so that the base station better supports the cleaning device.

The cleaning device comprises a floor brush assembly comprising a floor brush housing and a roller controlled by a drive unit. In the process of cleaning the cleaning equipment, the roller is in contact with the working surface, and the driving unit drives the roller to rotate, so that the working surface is cleaned.

The direction of rotation of the drum can be changed. Specifically, the drum rotates in a first direction relative to the floor brush housing for a first period of time; and rotates in a second direction relative to the floor brush housing for a second length of time.

In the existing cleaning equipment, rollers all rotate along the same direction to perform cleaning work. During long-time use, the brush hair of cylinder can laminate gradually with clean body, and this can make the magnitude of interference between cylinder and the working face littleer and less, leads to clean effect more and more poor, influences user's use impression very much. The brush hair rotates along a single direction for a long time, the brush hair collapses to be attached to the body of the roller, the water absorption of the brush hair is poorer and poorer, and a water film on the roller is thicker and heavier. In addition, most rollers on the market can be matched with a water scraping plate for use, and sewage and foreign matters adsorbed in the rollers can be extruded out through the water scraping plate. The bristles of the roller are extruded by the water scraping plate to deform, so that the service life of the roller is shortened, and the water film phenomenon is more serious.

The cleaning system of the present disclosure, in turn, rotates the drum about its own axis in a first direction for a first period of time and about its own axis in a second direction for a second period of time. Through changing the direction of rotation of cylinder to make the brush hair of cylinder toward different direction swings in the length of time of difference, in order to avoid the long-time problem appearance that the brush hair that leads to of rotating along the single direction collapses of cylinder. Therefore, the cleaning effect of the cleaning equipment can be kept in a good state for a long time, and the service life of the roller can be further prolonged.

For a better understanding, the specific structure of the cleaning system of the present disclosure and the working principle thereof will be described in detail below with reference to fig. 1 to 12 of the drawings attached to the specification.

Example 1

The present embodiment provides a cleaning system, and referring to fig. 1, the cleaning system includes a cleaning apparatus 1 and a base station 2.

Cleaning device 1 includes scrubbing brush subassembly 11, fuselage subassembly 15, continues to refer to fig. 1, and wherein fuselage subassembly 15 rotates with scrubbing brush subassembly 11 and is connected, so make the user can be as required according to the use, the dynamic adjustment fuselage subassembly 15 and the connection angle between scrubbing brush subassembly 11, the user of being convenient for carries out cleaning.

Referring specifically to fig. 2, the body assembly 15 includes a body housing 16, and a changeover switch 3 provided on the body housing 16. Referring to fig. 3 and 6, the floor brush assembly 11 includes a floor brush housing 12, and a drum 121 controlled by a driving unit 14. The drum 121 is configured to contact a work surface, such as a floor, to perform a cleaning work. Referring to fig. 10 and 11, an output end of the driving unit 14 is rotatably connected to at least one end of the drum 121. In this way, the driving unit 14 can rotate the drum 121.

The base station 2 is configured for placing the cleaning device 1. In order that the cleaning device 1 can be stably placed, the base end face of the base station 2 is configured in a shape that fits the bottom face of the cleaning device 1. The base station 2 may charge the cleaning device 1, the cleaning device 1 may also perform a self-cleaning operation at the base station 2, and the like, and the base station 2 is common knowledge of those skilled in the art and will not be described in detail herein.

During the cleaning operation performed by the cleaning apparatus 1, since the roller 121 is in contact with the work surface and is kept rotating under the control of the driving unit 14, the position where the roller 121 meets the work surface is gradually worn. Specifically, the external structure of the roller 121 may gradually adhere to the body of the roller 121, which causes the interference between the roller 121 and the working surface to gradually decrease, and the cleaning effect of the cleaning apparatus 1 is deteriorated. This can be avoided by changing the direction of rotation of the drum 121. The reverse rotation enables the bristles of the drum 121 to reversely swing under the centrifugal force, which is beneficial to maintaining the stability of the external structure of the drum 121, thereby realizing the protection of the drum 121.

In the cleaning system of the present disclosure, the control roller 121 rotates about its own axis in the first direction for a first period of time, and the control roller 121 rotates about its own axis in the second direction for a second period of time. It should be noted that the first direction and the second direction of the present disclosure refer to not the rotation direction of the driving unit 14, but the rotation direction of the drum 121 around its own axis with respect to the floor brush housing 12.

In one embodiment of the present disclosure, the switching of the rotation direction of the drum 121 in the first time period and the second time period is achieved by controlling the drum 121 to rotate forward or backward after the drum 121 is mounted on the floor brush housing 12 with the drum 121 as a reference. The first direction may be, for example, clockwise rotation and the second direction may be counterclockwise rotation. Of course, the first direction may be counterclockwise rotation and the second direction may be clockwise rotation. In this embodiment, the driving unit 14 drives the drum 121 to rotate forward and backward.

In another embodiment of the present disclosure, the rotation of the drum 121 in two directions may also be achieved by switching the installation direction of the drum 121 on the floor brush housing 12. For example, during a first period of time, the driving unit 14 controls the drum 121 to rotate about its own axis in a first direction, and the bristles of the drum 121 oscillate in the first direction by the centrifugal force. During the second period, the roller 121 is removed and reversely mounted on the floor brush housing 12, and at this time, although the driving unit 14 still keeps rotating in the same direction, the roller 121 itself rotates around its own axis in the second direction relative to the first direction during the first period, and the bristles of the roller 121 swing in the second direction under the action of centrifugal force.

The following is a detailed description of the two embodiments described above.

In some embodiments of the present disclosure, the cleaning system further comprises a control unit. The control unit is configured to control the drum 121 to rotate in the first direction for a first period of time and to control the drum 121 to rotate in the second direction for a second period of time.

In practical use, the control unit may be in communication with the driving unit 14, and the control unit is configured to switch the rotation direction of the drum 121 by sending a control signal to the driving unit 14, so that the driving unit 14 is controlled.

In some embodiments of the present disclosure, the first length of time is the length of time that the cleaning apparatus 1 performs a work surface cleaning step, and the second length of time is the length of time that the cleaning apparatus 1 performs the next work surface cleaning step.

Specifically, during the first period, the cleaning apparatus 1 performs the current cleaning operation on the working surface, and the roller 121 always rotates in the first direction, for example, clockwise, to clean the working surface. After the cleaning apparatus 1 finishes the current cleaning work, the user turns off the cleaning apparatus 1.

When the user starts the cleaning device 1 again to perform the next cleaning work. At the same time, the control unit outputs a control signal to the driving unit 14, causing the drum 121 to change the rotation direction under the control of the driving unit 14. The time period of the cleaning work is the second time length. During the second period, the roller 121 is always rotated in the second direction for cleaning, for example, the control unit controls the roller 121 to rotate counterclockwise to clean the working surface.

This enables the cleaning apparatus 1 to change the rotational direction of the drum 121 when performing different cleaning operations, since the first direction is opposite to the second direction. The damage to the structure of the roller 121 due to the long-term rotation in a single direction is avoided, so that the roller 121 is protected, and the interference magnitude between the roller 121 and the working surface can be always in a stable range. The cleaning effect of the drum 121 and the service life thereof are effectively improved.

Further, the control unit automatically switches the rotation direction of the roller 121 during different cleaning operations, and can avoid situations such as the user forgetting to switch the rotation direction of the roller 121.

In another embodiment of the present disclosure, the first and second periods are different periods of time within which the cleaning apparatus 1 performs the current working surface cleaning step. Specifically, the first time period and the second time period are different time periods when the cleaning device 1 performs the same cleaning operation.

In actual use, the control unit may switch the rotation direction of the drum 121 by sending a control signal to the driving unit 14 at any time when the user performs the work surface cleaning using the cleaning apparatus 1.

When the cleaning apparatus 1 is activated to perform the cleaning of the working surface, the current rotational direction of the drum 121 is defined as a first direction. Correspondingly, the time length of cleaning in the first direction is the first time length. When the control unit outputs the control signal, the rotation direction of the drum 121 is changed. The rotation direction of the drum 121 at this time is referred to as a second direction, and the time period of the rotation in the second direction is a second time period.

It is to be noted that the first time period and the second time period are both within the time period during which the cleaning apparatus 1 performs the current cleaning operation. The control unit can still change the rotation direction of the drum 121 when the drum 121 rotates in the second direction for the second period of time. The rotation direction of the drum 121 can be switched at any time as long as the cleaning apparatus 1 does not end the current cleaning work.

In some embodiments of the present disclosure, the control unit is configured to control the driving unit 14 to switch the rotation direction of the drum 121 based on a preset time interval. Specifically, the time interval may be a preset time period inside the cleaning system, or may be a time period set by a user according to actual use requirements.

The rotation direction of the drum 121 is changed at intervals by a preset time period, and the drum 121 is controlled to switch the rotation direction every 10 seconds, for example. The rotation time period of the drum 121 in the first direction and the second direction is equalized to avoid the occurrence of the rotation time period of the drum 121 in one direction being much longer than that in the other direction. By averaging the length of rotation of the distribution drum 121 in different directions, the drum 121 can be maximally protected and its service life extended.

In some embodiments of the present disclosure, the cleaning device 1 further comprises a diverter switch 3. Referring to fig. 2, the top of the body assembly 15 is designed as a handle structure to facilitate gripping by a user. The switch 3 may be provided on the body housing 16 in the region near the handle structure, and further, the switch 3 is provided at a position convenient for the user to control.

The diverter switch 3 is in communication connection with the control unit. The control unit is configured to send a control signal to the driving unit 14 based on the switching signal input from the switch 3 to effect switching of the rotational direction of the drum 121.

In detail, the user can change the rotation direction of the drum 121 about its own axis by clicking the switch 3 at any time during the use of the cleaning apparatus 1. So that the user can change the rotation direction of the drum 121 at any time according to the actual environment or his/her needs. For example, when the user observes that the working face is unclean or remains on the working face and has the water stain, accessible change over switch 3 control cylinder 121 antiport to with the working face sanitization, this has improved user's experience, has guaranteed clear effect.

In some embodiments of the present disclosure, the first time period is a time period when the cleaning apparatus 1 performs the working surface cleaning step, and the second time period is a time period when the cleaning apparatus 1 performs the self-cleaning step on the base station 2.

In actual use, the operating time period when the cleaning apparatus 1 performs the working surface cleaning is defined as a first time period. Then the cylinder 121 rotates in a first direction for a first period of time, for example, the cylinder 121 always rotates in a clockwise direction while the cylinder 121 is cleaning a work surface. When cleaning is completed, the user may place cleaning apparatus 1 on base station 2 and initiate the self-cleaning mode of cleaning apparatus 1. The operation time period of the self-cleaning mode is defined as a second time period, and the rotation direction of the drum 121 when performing self-cleaning may be noted as a second direction, for example, counterclockwise rotation. The way in which the cleaning device 1 performs self-cleaning on the base station 2 is well known to the person skilled in the art and will not be described in detail here. When it is desired to clean the work surface, the cleaning device is removed from the base station 2 and the drum 121 continues to rotate in the first direction, thereby cleaning the work surface.

When the cleaning apparatus 1 performs different cleaning task steps, the rotation direction of the drum 121 is changed by the control of the control unit to protect the drum 121, extending the cleaning effect and the service life of the drum 121.

In a specific embodiment of the present disclosure, when the cleaning apparatus 1 is placed on the base station 2 and performs the self-cleaning operation step, the control unit can also switch the rotation direction of the drum 121 during the current self-cleaning operation period. The specific principle and structure have been described in detail above, and will not be described in detail herein.

In the above-described embodiment, as long as the control unit switches the rotation direction of the drum 121 to protect the outer structure of the drum 121, the interference between the drum 121 and the working surface and the cleaning effect of the drum 121 are maintained in a stable state for a long period of time. Based on the above disclosure, a person skilled in the art can select a specific design according to actual needs, and the design is not limited herein.

In some embodiments of the present disclosure, referring to fig. 4, the drum 121 is a drum 121 rotatably connected to the floor brush housing 12, and a rotation axis of the drum 121 is configured to be parallel to the working surface.

Referring to the view direction of fig. 8, the direction in which the drum 121 rotates clockwise is defined as a first direction, i.e., the drum 121 rotates in the first direction may be understood as the drum 121 now performs clockwise rotation. With continued reference to fig. 9, the direction in which the drum 121 rotates counterclockwise is defined as a second direction. Of course, for those skilled in the art, the first direction may also be counterclockwise rotation, and the second direction may also be clockwise rotation, only the rotation direction of the cleaning device 1 can be described more clearly below, and the rotation directions of the first direction and the second direction are not limited.

In some embodiments of the present disclosure, referring to FIG. 7, a wiper strip 122 is also provided on the scrubber housing 12. The wiper strip 122 abuts against the drum 121 in the floor brush assembly 11, and is configured to wipe off dirt, which is a mixture of dirty water and foreign substances, on the drum 121.

In actual use, the drum 121 is always kept in a rotating state when the cleaning apparatus 1 performs a cleaning operation. The bar 122 is pressed against the drum 121 to scrape the contaminated water and foreign materials on the drum 121 off the surface of the drum 121. The floor brush shell 12 is further provided with a dirt suction port 123. With continued reference to fig. 7, the soil suction port 123 is provided in a lower region of the bar 122, and soil scraped off from the drum 121 falls in the direction of the soil suction port 123 and is sucked into the soil suction port 123.

Further, bristles are attached to the outer surface of the drum 121. When the roller 121 performs a cleaning operation in a clockwise or counterclockwise direction for a long time, the bristles are pressed against the roller 121 while the wiper strip 122 is continuously pressed. The bristles are gradually adhered to the body of the roller 121, so that the moisture attached to the roller 121 can only stay on the surface of the roller 121, and a water film is formed on the outer surface of the roller 121. Therefore, when the roller 121 is cleaned, water marks may be left on the working surface, which may affect the cleaning effect.

In order to avoid this, the bristles are reversely scraped by the scraping bar 122 by changing the rotation direction of the drum 121. The proper distance is kept between the brush and the roller 121 body, so that the water absorption effect and the cleaning effect of the roller 121 are controlled.

Referring to fig. 9, the drum 121 rotates counterclockwise, and the dirt adhered to the drum 121 is scraped by the scraping bar 122, and the scraped dirt falls below the scraping bar 122, so that the dirt suction port 123 can suck the dirt and keep the working environment of the drum 121 clean.

In one embodiment of the present disclosure, referring to fig. 8, the roller 121 rotates clockwise, and the scraper bar 122 scrapes dirt on the roller 121 to an area above the scraper bar 122, and cannot be sucked by the dirt suction port 123. It is therefore necessary to provide the gap 124 so that dirt can flow through the gap 124 from the area above the wiper strip 122 to the area where the dirt suction port 123 is located and be sucked away by the dirt suction port 123.

In one particular embodiment of the present disclosure, referring to fig. 12, the notch 124 is provided on the wiper strip 122. In this way, dirt in the area above the wiper strip 122 can flow through the notch 124 to the area below the wiper strip 122 and be sucked away by the dirt suction port 123.

In some embodiments of the present disclosure, with continued reference to fig. 12, a notch 124 is provided in the area between the wiper strip 122 and the cylinder 121. Specifically, the end of the bar 122 contacting the cylinder 121 has a saw-tooth shape with a flange. The flange portion can scrape off dirt on the drum 121, and the dirt can flow to the dirt suction port 123 along a gap between two adjacent flanges, so that the dirt suction port 123 sucks the dirt away.

In some embodiments of the present disclosure, a gap 124 is provided in the area between the wiper strip 122 and the floor brush housing 12, and dirt in the area above the wiper strip 122 can flow through the gap 124 to the area below the wiper strip 122 and be sucked away by the dirt suction port 123.

The scraping strip 122 of the present disclosure may be in the shape of a strip, and the scraping strip 122 may also be configured in a cylindrical shape, etc. After the scraper bar 122 scrapes off the dirt on the roller 121, the dirt in the space above the scraper bar 122 can flow into the lower part of the scraper bar 122 and be sucked away by the dirt suction port 123, which is not limited herein.

In one embodiment of the present disclosure, the drum 121 is switchably mounted on the floor brush housing 12. Referring to fig. 6, the floor brush housing 12 is provided with two oppositely disposed arms, and opposite ends of the roller 121 are rotatably coupled to the two arms, thereby allowing the roller 121 to rotate relative to the floor brush housing 12. Referring to fig. 11, a driving unit 14 is provided on one of the arms of the floor brush housing 12, and an output end of the driving unit 14 is coupled to one end of the roller 121, and the other end is rotatably coupled to the other arm by a rotating member. The structure of both ends of the roller 121 may be the same, so that either end of the roller 121 may be rotatably connected to either arm, thereby allowing the installation direction of the roller 121 to be changed.

Specifically, referring to fig. 4, two points are arbitrarily taken on the drum 121, and are denoted as a point a and a point B. The opposite ends of the drum 121 are respectively marked as a first end and a second end, and the first end of the drum 121 is an end of the drum 121 far from the point a and the point B. At this time, the first end of the roller 121 is rotatably connected to the output end of the driving unit 14, and the second end of the roller 121 is rotatably connected to the other arm.

In this embodiment, the drum 121 rotates in a counterclockwise direction. Referring to the view direction of fig. 4, when the drum 121 rotates counterclockwise, the point B on the drum 121 passes the bar 122 first, and then the point a passes the bar 122. It can now be understood that the drum 121 is rotated in a first direction so that the hanging strip 122 first scrapes over the point B and then over the point a.

With continued reference to FIG. 4, the user may remove the roller 121 from the floor brush housing 12 and reverse the installation direction of the roller 121, i.e., install the second end of the roller 121 on the output end of the drive unit 14 and the first end of the roller 121 on the other arm. The mounting position and the rotational direction of the drive unit 14 remain unchanged, and the rotation is still performed in the counterclockwise direction. Referring to fig. 5, when the drum 121 rotates counterclockwise due to the direction of the drum 121, the point a on the drum 121 passes the bar 122 first, and then the point B passes the bar 122.

In this embodiment, the rotational direction of the drive unit 14 is not changed at this time. The rotation direction of the drum 121 is changed with respect to the floor brush housing 12. It is understood that the roller 121 is rotated in the second direction, and the bar 122 passes through the point a and then the point B.

In the above embodiment, the user manually turns the direction of the drum 121. The direction of mounting of the drum 121 can of course be reversed by an automated control device which can be mounted on the base station 2 or elsewhere, whereby switching of the drum 121 in both directions can be effected.

In this embodiment, the drum 121 may be controlled to rotate in the first direction for the first period; during the second period, the installation direction of the drum 121 is reversed such that the drum 121 can be rotated in the second direction.

After the preset time period, the control unit sends a control signal to the driving unit 14, and the driving unit 14 changes the rotation direction of the roller 121, so that the roller 121 rotates in the second direction to clean the working surface.

The first direction and the second direction are 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 are not pressed on the body of the roller 121 in one direction, so that the interference between the roller 121 and the working surface can be ensured and always kept in a stable state.

Application scenario 2

When a user holds the cleaning apparatus 1 by hand or controls the cleaning apparatus 1 to perform a cleaning work for cleaning a work surface. The driving unit 14 inside the cleaning apparatus 1 drives the drum 121 to rotate in a first direction to clean the work surface.

This cleaning device 1 carries out clear in-process to the working face handheld at the user, when the user finds that certain position of working face still has dirty or leaves the water stain after the cleanness, can press change over switch 3, and control unit controls cylinder 121 and switches the direction of rotation after receiving the switching signal of change over switch 3 input, even cylinder 121 rotates in the second direction, continues to clean dirty or the position of leaving the water stain on the working face.

After the direction of the roller 121 is changed, the bristles on the roller 121 swing in the other direction, so that the bristles pressed on the roller 121 are in a relatively fluffy state, the water absorption of the bristles is improved, and the cleaning effect of the cleaning equipment 1 is ensured.

Application scenario 3

When a user holds the cleaning apparatus 1 by hand or controls the cleaning apparatus 1 to perform a cleaning work for cleaning a work surface. The driving unit 14 inside the cleaning apparatus 1 drives the drum 121 to rotate in a first direction to clean the work surface.

When the cleaning of the working surface is completed, the user may place the cleaning device 1 on the base station 2, and when the user presses the self-cleaning button, the clean water tank in the cleaning device 1 supplies water to the drum 121, and the drum 121 rotates in the second direction to self-clean the drum 121. When the user needs to use the cleaning device 1 to clean the working surface, the control unit controls the roller 121 to rotate in the first direction to clean the working surface.
