Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a control device for a scraper and a cleaning equipment. Background Technology

[0002] Cleaning equipment, used for cleaning floors or countertops, typically includes a floor brush, the main body of the floor scrubber, a cleaning and charging base, a wastewater tank, a clean water tank, a motor and battery assembly, and other accessories. The floor brush consists of a roller brush, a water spray assembly, a squeegee, a suction channel, a roller brush motor, and a water pump. The cleaning and charging base generally has both self-cleaning and charging functions. After the floor scrubber has finished washing and mopping the floor, dirt may adhere to the roller brush and brush chamber. Placing the floor scrubber on the cleaning and charging base allows it to self-clean through the cleaning tank on the charging base, the squeegee on the floor scrubber, and the rotation of the roller brush.

[0003] However, after the floor scrubber performs self-cleaning, dirt usually still adheres to the roller brush chamber, resulting in incomplete self-cleaning and poor cleaning effect. Utility Model Content

[0004] In view of this, the present invention provides a control device and cleaning equipment for a scraper to solve the problem that dirt still adheres to the roller brush cavity after the floor scrubber has self-cleaned, resulting in incomplete self-cleaning and poor cleaning effect.

[0005] In a first aspect, this utility model provides a control device for a scraper, the scraper being movably connected to a floor scrubber and having a first cleaning position abutting against a roller brush and a second cleaning position separated from the roller brush; the control device includes:

[0006] A drive structure, in cooperation with the scraper, is used to drive the scraper to move from the first cleaning position to the second cleaning position;

[0007] A reset structure is connected between the floor scrubber and the squeegee, used to drive the squeegee to reset from the second cleaning position to the first cleaning position.

[0008] Beneficial effects: By designing the drive structure, during self-cleaning, the scraper can overcome the resetting force of the reset structure to move from the first cleaning position to the second cleaning position, thus creating an interval between the scraper and the roller brush. When the roller brush rotates, a complete annular water film can be formed on its surface. This film not only cleans the roller brush but also washes the roller brush cavity, removing dirt and achieving a better cleaning effect. Furthermore, the reset structure allows the scraper to move from the second cleaning position to the first cleaning position without applying force. A force is then applied to the scraper to maintain it in the first cleaning position, causing it to contact the roller brush. During the cleaning process, the scraper removes wastewater, dust, and other debris from the roller brush. This debris falls near the suction port and is sucked into the wastewater tank, effectively completing the cleaning process.

[0009] In one optional implementation, the driving structure includes:

[0010] A pressing drive is rotatably connected to a cleaning charging base, the pressing drive including a pressure end and a driving end;

[0011] A first elastic element is connected between the cleaning charging base and the pressing drive element;

[0012] The pressure-receiving end has a first position protruding from the cleaning and charging base under the drive of the first elastic member, and a second position retracting into the cleaning and charging base under the pressure of the floor scrubber placed on the cleaning and charging base; the driving end is used to cooperate with the scraper when the floor scrubber is placed on the cleaning and charging base.

[0013] Beneficial effects: When the floor scrubber is placed on the cleaning charging base, the pressure end moves from the first position to the second position under the action of gravity of the floor scrubber, overcoming the elastic force of the first elastic element, and drives the drive end to rotate. The scraper that cooperates with the drive end moves from the first cleaning position to the second cleaning position under the drive of the drive end, overcoming the reset force of the reset structure. This makes the scraper and the roller brush spaced apart. If the roller brush is driven to rotate for self-cleaning at this time, a complete annular water film can be formed on the surface of the roller brush. In addition to cleaning the roller brush, the complete annular water film can also rinse the roller brush cavity, cleaning the dirt adhering to the roller brush cavity, achieving a better cleaning effect. After the floor scrubber is removed from the cleaning and charging base, the pressure end is no longer subjected to pressure from the scrubber. Under the elastic force of the first elastic element, the pressure end returns from the second position to the first position, driving the drive end to rotate and reset. The drive end separates from the scrubber and no longer applies force to the scraper. The reset force of the reset structure drives the scraper to move from the second cleaning position to the first cleaning position, applying a force to hold it in the first cleaning position, causing the scraper to contact the roller brush. During the cleaning process of the floor or countertop, the scraper scrapes off the wastewater, dust, and other debris from the roller brush. The scraped-off wastewater, dust, and other debris fall near the scrubber's suction channel and are sucked into the wastewater tank, thus effectively completing the cleaning process. The design of the press-driven component and the first elastic element allows for automatic control of the scraper's movement using the scrubber's own weight, eliminating the need for separate customer operation.

[0014] In one optional embodiment, the drive structure further includes a sliding plate slidably connected to the floor scrubber; one end of the sliding plate is connected to the scraper, and the other end is provided with a sliding hole; after the floor scrubber is placed on the cleaning and charging base, the drive end passes through the sliding hole.

[0015] Beneficial effects: Because the cleaning charging base has a cleaning groove, when the floor scrubber is placed on it, the roller brush extends into the cleaning groove, achieving self-cleaning through the water in the groove and the roller brush's rotation. Therefore, the sliding plate allows for spatial separation between the pressing drive and the cleaning groove, avoiding interference and facilitating the pressing end of the brush housing. Furthermore, the sliding hole allows the drive end to pass through and engage with the sliding plate, further simplifying the interaction between the drive end and the sliding plate.

[0016] In one alternative embodiment, the drive structure further includes a second elastic element, and one end of the sliding plate is connected to the scraper via the second elastic element.

[0017] Beneficial effects: By setting the second elastic element, the sliding force of the sliding plate can be transmitted to the scraper, and it plays a buffering role, which can better adapt to movement in different directions.

[0018] In one alternative embodiment, the sliding plate is slidably connected inside the housing of the floor scrubber, the housing having an insertion hole, and the drive end passing through the insertion hole and engaging with the sliding hole.

[0019] Beneficial effects: The sliding plate is slidably connected inside the casing of the floor scrubber, which can protect the sliding plate and maintain the integrity of the bottom of the floor scrubber, avoiding friction and interference between the sliding plate and the floor or countertop when the floor scrubber is cleaning; the insertion hole allows the drive end located outside the casing to enter the casing through the insertion hole and cooperate with the sliding hole on the sliding plate.

[0020] In one optional embodiment, the drive structure further includes a sliding cover plate, which is fixedly connected to the floor scrubber and forms a sliding cavity with the floor scrubber, and the sliding plate is slidably disposed within the sliding cavity.

[0021] Beneficial effects: The sliding cover can both protect the sliding plate and limit its movement.

[0022] In one alternative embodiment, the sliding cover plate is further provided with a clearance hole, the clearance hole being positioned to match the sliding hole.

[0023] Beneficial effects: The setting of the clearance hole can avoid and limit the drive end, preventing the drive end from interfering with and rubbing against the sliding cover.

[0024] In one optional embodiment, the upper charging shell of the cleaning charging base is provided with a first through hole and a second through hole at intervals; the pressing drive is rotatably connected inside the cleaning charging base, the pressure-receiving end is movably inserted through the first through hole, and the driving end extends to the outside of the cleaning charging base through the second through hole.

[0025] Beneficial effects: The pressing drive is rotatably connected inside the cleaning charging base, which can protect the pressing drive. The first and second through holes facilitate the movement of the pressure end and the driving end, and can limit and guide the pressure end and the driving end respectively.

[0026] In one alternative embodiment, the pressing drive includes:

[0027] The main body rod has a rotating end at one end and a resetting end at the other end. The rotating end is rotatably connected to the charging base of the cleaning charging dock. The first elastic element is connected between the resetting end and the charging base.

[0028] The pressure rod has one end connected to the reset end and the other end as the pressure end;

[0029] The drive rod has one end connected to the rotating end and the other end connected to the drive end.

[0030] Beneficial effects: The pressing drive component includes a main body rod, a pressure rod, and a drive rod. Its structure is simple, occupies little space on the cleaning charging base, and is easy to control. The first elastic element connects the reset end and the charging base shell, and is relatively far from the rotating end; therefore, the reset end can be reset with a small elastic force.

[0031] In one optional embodiment, the reset structure includes a reset spring, the two ends of which are respectively connected to the scraper and the floor scrubber.

[0032] Beneficial effects: The reset spring has a simple structure and makes it easy to apply a reset force to the scraper.

[0033] In one optional embodiment, the reset structure includes at least two, and the at least two reset structures are spaced apart along the length direction of the scraper.

[0034] Beneficial effects: The reset structure includes at least two parts, which can apply a relatively uniform force to the scraper along the length direction.

[0035] In one alternative embodiment, the control device has at least two sets, and the at least two sets of the control device are spaced apart along the length direction of the scraper.

[0036] Beneficial effects: The control device is set with at least two sets, which can apply a relatively uniform driving force to the scraper along the length direction, making it easier to control the scraper.

[0070] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0071] Cleaning equipment, used for cleaning floors or countertops, typically includes a floor brush, a floor scrubber 100 main body, a cleaning charging base 200, a wastewater tank, a clean water tank 108, a motor and battery assembly, and other accessories. The floor brush consists of a roller brush 102, a water spray assembly, a scraper 101, a suction channel, a roller brush 102 motor, and a water pump. The water spray assembly sprays water onto the roller brush 102 to wet it, and the wet roller brush 102 rolls on the floor, achieving a washing and mopping effect. During this process, the scraper 101 scrapes off wastewater, dust, and other debris from the roller brush 102. The scraped-off wastewater, dust, and other debris fall near the suction channel of the floor scrubber 100 and are sucked into the wastewater tank through the suction channel. The cleaning and charging base 200 of the floor scrubber 100 generally has two functions: self-cleaning and charging. When the battery pack of the floor scrubber 100 is low after a period of use, it can be charged by simply placing it on the cleaning and charging base 200. After the floor scrubber 100 has finished washing and mopping the floor, dirt will adhere to the roller brush 102 and roller brush chamber 104. At this time, placing the floor scrubber 100 on the cleaning and charging base 200 will enable self-cleaning through the cleaning groove on the cleaning and charging base 200, the squeegee 101 on the floor scrubber 100, and the rotation of the roller brush 102.

[0072] However, since the scraper 101 is always in contact with the bristles of the roller brush 102, the roller brush 102 cannot form a complete surrounding water film during self-cleaning, and cannot rinse the roller brush cavity 104. As a result, dirt will still adhere to the roller brush cavity 104, leading to incomplete self-cleaning and poor cleaning effect.

[0073] The following is combined with Figures 1 to 15 The following describes embodiments of the present invention.

[0074] According to an embodiment of the present invention, in one aspect, a control device for a scraper 101 is provided. The scraper 101 is movably connected to a floor scrubber 100 and has a first cleaning position abutting against a roller brush 102 and a second cleaning position separated from the roller brush 102. The control device includes a drive structure 1 and a reset structure 2. The drive structure 1 cooperates with the scraper 101 to drive the scraper 101 to move from the first cleaning position to the second cleaning position. The reset structure 2 is connected between the floor scrubber 100 and the scraper 101 and is used to drive the scraper 101 to reset from the second cleaning position to the first cleaning position.

[0075] By setting the drive structure 1, when the floor scrubber 100 is self-cleaning, it can overcome the reset force of the reset structure 2 to drive the scraper 101 to move from the first cleaning position to the second cleaning position, so that the scraper 101 and the roller brush 102 are spaced apart. At this time, when the roller brush 102 rotates, a complete annular water film can be formed on the surface of the roller brush 102. In addition to cleaning the roller brush 102, the complete annular water film can also rinse the roller brush cavity 104, cleaning the dirt adhering to the roller brush cavity 104, and achieving a better cleaning effect. By setting the reset structure 2, when the drive structure 1 does not apply force, the drive scraper 101 can be moved from the second cleaning position to the first cleaning position, and a force is applied to the scraper 101 to maintain it in the first cleaning position, so that the scraper 101 abuts against the roller brush 102. During the cleaning process of the floor scrubber 100 on the floor or countertop, the scraper 101 scrapes off the sewage, dust and other debris on the roller brush 102. The scraped-off sewage, dust and other debris fall near the suction channel of the floor scrubber 100 and are sucked into the sewage tank through the suction channel, thereby completing the cleaning process of the floor scrubber 100 better.

[0076] In a specific embodiment, the scraper 101 is movably connected to the housing 103 of the floor brush of the floor scrubber 100. The roller brush cavity 104 is surrounded by a roller brush cover plate 105 connected to the housing 103, and at least a portion of the roller brush 102 is rotatably disposed within the roller brush cavity 104. In the rotation direction of the roller brush 102, the scraper 101 is movably connected to one side of the outside of the roller brush cavity 104.

[0077] In one embodiment, the drive structure 1 includes a pressing drive member 11 and a first elastic member 12; the pressing drive member 11 is rotatably connected to the cleaning and charging base 200, and the pressing drive member 11 includes a pressure-receiving end 111 and a driving end 112; the first elastic member 12 is connected between the cleaning and charging base 200 and the pressing drive member 11; wherein, the pressure-receiving end 111 has a first position protruding from the cleaning and charging base 200 under the drive of the first elastic member 12, and a second position retracting into the cleaning and charging base 200 under the pressing of the floor scrubber 100 placed on the cleaning and charging base 200; the driving end 112 is used to cooperate with the scraper 101 when the floor scrubber 100 is placed on the cleaning and charging base 200.

[0078] When the floor scrubber 100 is placed on the cleaning charging base 200, the pressure end 111 moves from the first position to the second position under the action of gravity of the floor scrubber 100, overcoming the elastic force of the first elastic element 12, and drives the drive end 112 to rotate. The scraper 101, which cooperates with the drive end 112, moves from the first cleaning position to the second cleaning position under the drive of the drive end 112, overcoming the reset force of the reset structure 2, so that the scraper 101 and the roller brush 102 are spaced apart. If the roller brush 102 is driven to rotate for self-cleaning, a complete annular water film can be formed on the surface of the roller brush 102. In addition to cleaning the roller brush 102, the complete annular water film can also rinse the roller brush cavity 104, cleaning the dirt adhering to the roller brush cavity 104, and achieving a better cleaning effect. After the floor scrubber 100 is removed from the cleaning charging base 200, the pressure end 111 is no longer subjected to pressure from the floor scrubber 100. Under the elastic force of the first elastic element 12, the pressure end 111 returns to the first position from the second position and drives the drive end 112 to rotate and return to the first position. The drive end 112 separates from the floor scrubber 100 and no longer applies force to the scraper 101. The reset force of the reset structure 2 drives the scraper 101 to move from the second cleaning position to the first cleaning position and applies a force to the scraper 101 to maintain it in the first cleaning position, so that the scraper 101 abuts against the roller brush 102. During the cleaning process of the floor scrubber 100 on the floor or countertop, the scraper 101 scrapes off the sewage, dust and other debris on the roller brush 102. The scraped sewage, dust and other debris fall near the suction channel of the floor scrubber 100 and are sucked into the sewage tank through the suction channel, thus completing the cleaning process of the floor scrubber 100. By using the pressing drive component 11 and the first elastic component 12, the movement of the scraper 101 can be automatically controlled by the gravity of the floor scrubber 100 itself, without the need for separate operation by the customer.

[0079] As an alternative implementation, the drive structure 1 may include an automatic drive structure 1 such as a drive motor or a drive cylinder, with the power output end of the drive structure 1 connected to the scraper 101 to drive the scraper 101 to move from the first cleaning position to the second cleaning position.

[0080] As an alternative implementation, the drive structure 1 may include a drive rod 115 and a drive handle. The drive rod 115 is connected to the scraper 101, and the drive handle is connected to the drive rod 115. The drive handle extends to the outside of the housing 103 of the floor brush of the floor scrubber 100, so as to apply force to the drive rod 115 through the drive handle to drive the scraper 101 to move from the first cleaning position to the second cleaning position.

[0081] In a specific embodiment, the scraper 101 is rotatably connected to the floor scrubber 100. Alternatively, the scraper 101 is slidably connected to the floor scrubber 100. In this embodiment, it is preferable that the scraper 101 is rotatably connected to the floor scrubber 100, as the scraper 101 occupies less space and has a simple structure.

[0082] In one embodiment, the drive structure 1 further includes a sliding plate 13, which is slidably connected to the floor scrubber 100; one end of the sliding plate 13 is connected to the scraper 101, and the other end is provided with a sliding hole 131; after the floor scrubber 100 is placed on the cleaning charging base 200, the drive end 112 passes through the sliding hole 131.

[0083] Because the cleaning charging base 200 has a cleaning groove, when the floor scrubber 100 is placed on the cleaning charging base 200, the roller brush 102 extends into the cleaning groove, and the roller brush 102 achieves self-cleaning through the water in the cleaning groove and the rotation of the roller brush 102. Therefore, by setting the sliding plate 13, the pressing drive 11 and the cleaning groove can be spaced apart in terms of spatial position, which avoids interference and facilitates the pressing end 111 of the floor brush housing 103. Furthermore, by setting the sliding hole 131, the drive end 112 can be inserted into the sliding hole 131 to cooperate with the sliding plate 13, and it also facilitates the cooperation between the drive end 112 and the sliding plate 13.

[0084] Specifically, the sliding hole 131 is a strip-shaped hole arranged along the sliding direction.

[0085] In one embodiment, the driving structure 1 further includes a second elastic element 14, and one end of the sliding plate 13 is connected to the scraper 101 through the second elastic element 14.

[0086] By setting the second elastic element 14, the sliding force of the sliding plate 13 can be transmitted to the scraper 101, and it plays a buffering role, which can better adapt to movement in different directions.

[0087] In a specific implementation, the second elastic element 14 is an elastic tension spring.

[0088] In one embodiment, the sliding plate 13 is slidably connected inside the housing 103 of the floor scrubber 100. The housing 103 is provided with an insertion hole 1031, and the drive end 112 passes through the insertion hole 1031 and engages with the sliding hole 131.

[0089] The sliding plate 13 is slidably connected inside the housing 103 of the floor scrubber 100. It can protect the sliding plate 13 and maintain the integrity of the bottom of the floor scrubber 100, avoiding friction and interference between the sliding plate 13 and the floor or countertop when the floor scrubber 100 is cleaning. The insertion hole 1031 allows the drive end 112 located outside the housing 103 to enter the housing 103 and cooperate with the sliding plate 13.

[0090] In a specific embodiment, the insertion hole 1031 is a strip-shaped hole extending along the sliding direction, which can provide sufficient room for the drive end 112 to avoid interfering with the movement of the drive end 112, and also guide the movement of the drive end 112. When the scraper 101 is in the first cleaning position, the sliding hole 131 matches the position of the insertion hole 1031, which facilitates the cooperation between the drive end 112 and the sliding hole 131.

[0091] In one embodiment, the drive structure 1 further includes a sliding cover plate 15, which is fixedly connected to the floor scrubber 100 and forms a sliding cavity with the floor scrubber 100. The sliding plate 13 is slidably disposed in the sliding cavity.

[0092] The sliding cover 15 can both protect the sliding plate 13 and limit its movement.

[0093] In a specific embodiment, the floor scrubber 100's brush housing 103 includes a brush bottom shell 1032 and a brush top cover 1033. A sliding plate 13 and a sliding cover plate 15 are disposed between the brush bottom shell 1032 and the brush top cover 1033. A limiting groove protrudes from the brush bottom shell 1032, and an insertion hole 1031 is provided at the bottom of the limiting groove. The sliding cover plate 15 is detachably connected to the opening of the limiting groove, forming a sliding cavity with the sliding cover plate 15. The sliding plate 13 is slidably disposed within the sliding cavity. In a preferred embodiment, a fastener is provided on the groove wall of the limiting groove, and a buckle protrudes from the sliding cover plate 15, engaging with the fastener. The brush also includes a clean water tank 108, connected to the brush top cover 1033. The brush also includes a brush connector 106 and a booster wheel 107.

[0094] In one embodiment, the sliding cover plate 15 is further provided with a clearance hole 151, the clearance hole 151 being matched with the position of the sliding hole 131.

[0095] The clearance hole 151 is provided to allow the drive end 112 to be cleared and limited, preventing the drive end 112 from interfering with and rubbing against the sliding cover plate 15.

[0096] In a specific implementation, the clearance hole 151 is a strip-shaped hole arranged along the sliding direction.

[0097] In one embodiment, the charging upper shell 201 of the cleaning charging base 200 is provided with a first through hole 2011 and a second through hole 2012 spaced apart; the pressing drive member 11 is rotatably connected inside the cleaning charging base 200, the pressing end 111 is movably inserted through the first through hole 2011, and the driving end 112 extends to the outside of the cleaning charging base 200 through the second through hole 2012.

[0098] The pressing drive 11 is rotatably connected inside the cleaning charging base 200 and can protect the pressing drive 11. The first through hole 2011 and the second through hole 2012 facilitate the movement of the pressure end 111 and the driving end 112, and can limit and guide the pressure end 111 and the driving end 112 respectively.

[0099] In a specific embodiment, both the first perforation 2011 and the second perforation 2012 are strip-shaped holes extending along the sliding direction.

[0100] In one embodiment, the pressing drive 11 includes a body rod 113, a pressure rod 114, and a drive rod 115; one end of the body rod 113 is a rotating end and the other end is a reset end, the rotating end is rotatably connected to the charging base 202 of the cleaning charging base 200, and the first elastic member 12 is connected between the reset end and the charging base 202; one end of the pressure rod 114 is connected to the reset end, and the other end is the pressure end 111; one end of the drive rod 115 is connected to the rotating end, and the other end is the drive end 112.

[0101] The pressing drive component 11 includes a main body rod 113, a pressure rod 114, and a drive rod 115. It has a simple structure, occupies little space in the cleaning charging base 200, and is easy to control. The first elastic element 12 is connected between the reset end and the charging base 202, and is far from the rotating end. The reset end can be reset with a small elastic force.

[0102] In a specific embodiment, the charging base shell 202 has a protruding mounting groove, the opening of which faces the charging cover of the cleaning charging base 200, and the charging cover is connected to the charging base shell 202. Both walls of the mounting groove have rotating grooves, and rotating shafts protrude from both sides of the rotating end of the main body rod 113, rotatably disposed within the rotating grooves. Limiting ribs are provided on the walls of the mounting groove, slidingly engaging with the main body rod 113. A positioning groove is also provided on the walls of the mounting groove, and a first elastic element 12 is disposed within the positioning groove, one end connected to the bottom of the mounting groove, and the other end connected to the reset end of the main body rod 113. Preferably, the first elastic element 12 is a spring. The pressure rod 114 and the driving rod 115 are both perpendicular to the main body rod 113, and the length of the driving rod 115 is greater than that of the pressure rod 114.

[0103] In one embodiment, the reset structure 2 includes a reset spring, the two ends of which are connected to the scraper 101 and the floor scrubber 100, respectively.

[0104] The reset spring has a simple structure and is easy to apply a reset force to the scraper 101.

[0105] In one embodiment, the reset structure 2 includes at least two, and the at least two reset structures 2 are spaced apart along the length direction of the scraper 101.

[0106] The reset structure 2 includes at least two, which can apply a relatively uniform force to the scraper 101 along the length direction.

[0107] In one specific embodiment, the reset structure 2 includes two reset structures 2, which are respectively disposed at both ends of the scraper 101 in the length direction.

[0108] In one embodiment, the control device has at least two sets, and the at least two sets of the control device are spaced apart along the length direction of the scraper 101.

[0109] The control device is provided in at least two sets, which can apply a relatively uniform driving force to the scraper 101 along the length direction, making it easy to control the scraper 101.

[0110] According to an embodiment of the present invention, another aspect provides a cleaning device, including a floor scrubber 100, a cleaning charging base 200, and the aforementioned control device for the scraper 101. The floor scrubber 100 includes a scraper 101 and a roller brush 102. The scraper 101 is movably connected to the floor scrubber 100 and has a first cleaning position abutting against the roller brush 102 and a second cleaning position separated from the roller brush 102. The aforementioned control device for the scraper 101 includes a drive structure 1 and a reset structure 2. The drive structure 1 cooperates with the scraper 101 to drive the scraper 101 to move from the first cleaning position to the second cleaning position. The reset structure 2 is connected between the floor scrubber 100 and the scraper 101 and drives the scraper 101 to reset from the second cleaning position to the first cleaning position.

[0111] By setting the drive structure 1, when the floor scrubber 100 is self-cleaning, it can overcome the reset force of the reset structure 2 to drive the scraper 101 to move from the first cleaning position to the second cleaning position, so that the scraper 101 and the roller brush 102 are spaced apart. At this time, when the roller brush 102 rotates, a complete annular water film can be formed on the surface of the roller brush 102. In addition to cleaning the roller brush 102, the complete annular water film can also rinse the roller brush cavity 104, cleaning the dirt adhering to the roller brush cavity 104, and achieving a better cleaning effect. By setting the reset structure 2, when the drive structure 1 does not apply force, the drive scraper 101 can be moved from the second cleaning position to the first cleaning position, and a force is applied to the scraper 101 to maintain it in the first cleaning position, so that the scraper 101 abuts against the roller brush 102. During the cleaning process of the floor scrubber 100 on the floor or countertop, the scraper 101 scrapes off the sewage, dust and other debris on the roller brush 102. The scraped-off sewage, dust and other debris fall near the suction channel of the floor scrubber 100 and are sucked into the sewage tank through the suction channel, thereby completing the cleaning process of the floor scrubber 100 better.

[0112] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
