Description

Technical Field

[0001] This disclosure relates to a floor brush assembly and surface cleaning equipment. Background Technology

[0002] Wet surface cleaning equipment is suitable for cleaning hard floor surfaces, such as tile, hardwood floors, and soft carpet surfaces.

[0003] When cleaning a surface in a wet surface cleaning device, the cleaning liquid is first delivered to the cleaning module, and then applied to the surface through the cleaning module. When the cleaning module and the surface to be cleaned move relative to each other, the surface is cleaned.

[0004] After cleaning the surface, there will be cleaning liquid residue. At this time, it is necessary to use a squeegee to make pressure contact with the surface to remove the cleaning liquid, so that the surface can be relatively dry after wet cleaning.

[0005] In existing surface cleaning devices, the scraper is typically located behind the roller brush. In some scenarios, such as when the surface cleaning device is dragged backward, the roller brush may leave excessive cleaning liquid residue on the surface to be cleaned, resulting in a poor user experience.

[0087] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0088] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0089] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0090] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0091] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0092] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture.

Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0093] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0094] Figure 1 This is a schematic diagram of the structure of a surface cleaning device according to one embodiment of the present disclosure.

[0095] like Figure 1 As shown, this disclosure provides a surface cleaning device 10. In a preferred embodiment, the surface cleaning device 10 can be a wet vacuum cleaner.

[0096] The surface cleaning device 10 includes a body 100 and a floor brush assembly 200. The surface cleaning device 10 is supported by the floor brush assembly 200 during use and / or storage. The body 100 can be connected to the floor brush assembly 200. In an embodiment, the body 100 is connected to the floor brush assembly 200 via a pivoting connection. The connection between the body 100 and the floor brush assembly 200 allows the body 100 to pivot during use in the forward-backward direction of the cleaner's movement and relative to the left and right sides of the floor brush assembly 200, which are generally perpendicular or substantially perpendicular to the forward-backward direction of the cleaner's movement during use. In an embodiment, the pivoting connection allows the body 100 to be located within the perimeter of the floor brush assembly 200, i.e., within the front, rear, first, and second sides of the floor brush assembly 200, thereby placing the center of gravity of the surface cleaning device 10 within the footprint of the floor brush assembly 200. This allows the surface cleaning device 10 to be stored in an upright position.

[0097] It should be understood that in other embodiments, the body 100 may be fixed in a specific position relative to the floor brush assembly 200. In a further embodiment, the surface cleaning device 10 may be a handheld vacuum cleaner. In this case, the surface cleaning device 10 includes a handle 300 for a user to grip. The handle 300 may be located above the body 100. In an embodiment, the handle 300 may be located on top of the surface cleaning device 10.

[0098] The main body 100 houses a suction source, such as a motor, fan, impeller, etc., for generating a vacuum. In some embodiments, the motor may be a brushless motor. The suction source may be located at the top of the main body 100. In an embodiment, the suction source may be positioned adjacent to the handle 300.

[0099] A cleaning fluid supply tank 110 for holding cleaning fluid is supported on the main body 100. In use, the cleaning fluid supply tank 110 stores liquid for cleaning surfaces to be cleaned. For example, the cleaning fluid supply tank 110 may store a premixed cleaning solution for surface cleaning. In other embodiments, the cleaning fluid supply tank 110 may receive water. The cleaning fluid supply tank 110 is detachably connected to the main body 100, although it may also be fixed within the main body 100. In some embodiments, the cleaning fluid supply tank 110 is at least partially accommodated within a recess on the outer surface of the main body 100. In some examples, the cleaning fluid supply tank 110 is located on the front side of the main body 100, relative to the front-to-back direction of movement of the cleaner during use. The cleaning fluid supply tank 110 is also positioned close to or adjacent to a suction source.

[0100] The cleaning fluid supply tank 110 is fluidly connected to a cleaning fluid dispensing device on the floor brush assembly 200. In one specific embodiment, the cleaning fluid dispensing device is at least one nozzle for spraying cleaning fluid onto the agitator of the floor brush assembly 200. An additional nozzle may also alternatively or additionally spray cleaning fluid onto the surface to be cleaned. The cleaning fluid dispensing device is fluidly connected to the cleaning fluid supply tank 110 via fluid channels extending from the body 100 and through to the floor brush assembly 200, allowing cleaning fluid to be transferred from the cleaning fluid supply tank 110 to the cleaning fluid dispensing device.

[0101] The main body 100 also supports a dirt collection can 120 fluidly connected to the suction source. The dirt collection can 120 is fluidly connected to the dirty air outlet of the floor brush assembly 200. The dirt collection can 120 may include an air / liquid separator for separating the dirty cleaning fluid drawn from the surface to be cleaned, along with any entrained dirt and air. The dirt collection can 120 is detachably connected to the main body 100 of the surface cleaning device 10, although it can also be fixed within the main body 100. The dirt collection can 120 is located in the lower half of the main body 100, closer to the floor brush assembly 200 than the handle 300. The dirt collection can 120 is located at the rear of the main body 100 relative to the forward / backward direction of movement of the cleaner during use.

[0102] Figure 2 This is a schematic diagram of the structure of a floor brush assembly 200 according to one embodiment of the present disclosure. Figure 3 This is a structural schematic diagram of a floor brush assembly 200 according to one embodiment of the present disclosure from another angle.

[0103] like Figure 2 and Figure 3 As shown, the floor brush assembly 200 may include a housing 210. When the surface cleaning device of this disclosure is in operation, the housing 210 is movable along the surface to be cleaned. In a specific embodiment, the housing 210 may include a front side 211 and a rear side 212; moreover, the housing 210 may also include a first side 213 and a second side 214 extending between the front side 211 and the rear side 212. In this case, the front side 211, the rear side 212, the first side 213, and the second side 214 define a perimeter that defines the floor area occupied by the floor brush assembly 200.

[0104] In this disclosure, the first side 213 and the second side 214 can be two sides in the left-right direction (i.e., the lateral direction). For example, the first side 213 can be the right side and the second side 214 can be the left side.

[0105] The floor brush assembly 200 also includes an agitator 220 rotatable about an axis within a cavity at least partially defined by the housing 210. This axis is generally parallel to the surface to be cleaned and orthogonal to the forward and backward direction of the cleaner during use. In one embodiment, the agitator 220 includes a first support roller 221, a second support roller 222, and a flexible cleaning element 223 wound around the first and second support rollers 221 and 222. The first support roller 221 is driven to rotate, thereby forming the first support roller 221 as the active roller of the surface cleaning device 10. The second support roller 222 is arranged parallel or substantially parallel to the first support roller 221 and is driven to rotate by the first support roller 221; of course, the first support roller 221 may not be parallel to the second support roller 222, but when the second support roller 222 and the first support roller 221 are parallel, the portion of the flexible cleaning element 223 located below the first and second support rollers 221 can fully contact the surface to be cleaned. The first support roller 221 drives the second support roller 222 via the flexible cleaning element 223. In other words, the flexible cleaning element 223 functions as a cleaning component, cleaning the surface when it contacts it. It also acts as a conveyor belt. The flexible cleaning element 223 is positioned on and around the first and second support rollers 221 and 222, and the first support roller 221 drives the second support roller 222 via the flexible cleaning element 223. In some embodiments, the outer diameter of the first support roller 221 is larger than the outer diameter of the second support roller 222. When the surface cleaning device 10 is used to clean the surface, with the direction of movement of the surface cleaning device forward, the first support roller 221 is located behind the second support roller 222. This allows the surface cleaning device 10 to form a sharper front section, enabling it to clean hard-to-reach areas such as corners.

[0106] The floor-facing surface of housing 210 extends between front side 211, rear side 212, first side 213, and second side 214. In use, the floor-facing surface faces the surface to be cleaned. The floor-facing surface includes a floor wiping device, in this embodiment a scraper 230. The scraper 230 is located in front of the agitator 220. The floor-facing surface includes a suction port 240 through which air carrying dirt and dirty cleaning fluid can be received. The chamber of the floor brush assembly 200 is defined at least partially by a rear chamber wall. The rear chamber wall defines the suction port 240. The suction port 240 is in fluid communication with the chamber. The chamber has an opening facing the surface to be cleaned, through which at least a portion of the agitator 220 can be exposed.

[0107] Thus, the stirrer 220 of this disclosure can be rotatably disposed in the housing 210, at least partially located in the cavity of the housing 210, and configured to be close to the suction port 240, thereby allowing dirt and cleaning liquids detached from the stirrer 220 to be smoothly collected against the rear cavity wall and enter the suction port 240.

[0108] Figure 4 This is a schematic diagram of the structure of a floor brush assembly according to one embodiment of the present disclosure. Figure 5 This is a schematic diagram of the scraper according to one embodiment of the present disclosure.

[0109] like Figure 4 and Figure 5 As shown, the floor brush assembly 200 of this disclosure may further include a scraper 230, which is disposed in the housing 210 and located in front of the agitator 220. In other words, the scraper 230 of this disclosure is formed as the front end of the floor brush assembly 200.

[0110] See again Figure 4 and Figure 5 The scraper 230 is attached to the floor-facing surface of the housing 210. The scraper 230 extends laterally (but not entirely to each side, though it may) between the first side 213 and the second side 214 of the housing 210 for selectively wiping or contacting the surface to be cleaned. In an embodiment, the scraper 230 extends substantially linearly between the first side 213 and the second side 214.

[0111] The first and second sides of the housing 210 define the trajectory path for the scraper 230 to move up and down. For example, the first and second sides of the housing 210 can guide the up and down movement of the scraper 230.

[0112] The scraper 230 includes a first portion 231 for scraping liquid from the surface to be cleaned. The scraper 230 includes a second portion 232 connected to the first portion 231. The first portion 231 extends longitudinally along the second portion 232 in a direction generally perpendicular to the ground, and also extends generally linearly laterally along the second portion 232. In an embodiment, the first portion 231 extends laterally linearly along the second portion 232, generally parallel to the axis of the drive shaft of the agitator 220.

[0113] In the current embodiment, the first portion 231 also includes an absorbent material for absorbing liquid from the surface to be cleaned, rather than simply scraping the liquid off the surface. For example, the first portion 231 may include one or more of the following materials: microfibers, open-cell foam, fleece, chamois, cloth, cotton, polyester, polyethylene, nylon, or acrylic. However, other absorbent materials may be used without departing from the scope of the invention.

[0114] The cross-sectional shape / profile of the first portion 231, when viewed in a direction perpendicular or substantially perpendicular to the drive axis of the stirrer 220, remains substantially constant along its length. The first portion 231 may be substantially rectangular in a side view cross-section perpendicular or substantially perpendicular to the axis of the stirrer 220. However, in other embodiments, the first portion 231 may be substantially triangular or circular, or any other polygonal shape, in a side view cross-section perpendicular or substantially perpendicular to the axis of the stirrer 220.

[0115] In each example, the scraper 230 has a free end away from the surface facing the floor and a proximal end close to the surface facing the floor; in some examples, the proximal end is formed on a first portion 231. The free end is formed on a second portion 232.

[0116] The second portion 232 also extends generally linearly between the first side 213 and the second side 214. In this embodiment, the second portion 232 extends generally parallel to the axis of the agitator 220. The second portion 232 is further away from the floor surface awaiting cleaning than the first portion 231.

[0117] The cross-sectional shape / profile of the second portion 232, when viewed in a direction perpendicular or substantially perpendicular to the axis of the stirrer 220, remains substantially constant along its length. In the example shown, the second portion 232 is generally T-shaped in a side cross-section, with its transverse segment 2321 and longitudinal segment 2322 forming this general shape. However, in other embodiments, the second portion 232 may be generally rectangular in a side cross-section perpendicular or substantially perpendicular to the axis of the stirrer 220.

[0118] The longitudinal segment 2322 of the second part 232 forms the free end of the scraper 230 for connection with the adjustment assembly 250 (described in detail below). Under the action of the adjustment assembly 250, the scraper 230 is moved between a cleaning position and a non-cleaning position by driving the second part 232. In the cleaning position, the proximal end of the scraper 230 engages with the surface to be cleaned to scrape and / or wipe away moisture. At this time, the passage from the front end of the brush assembly 200 to the agitator 220 is closed, and the scraped and collected moisture is transported to the agitator 220, then transferred to the suction port 240, and further vacuumed into the dirt collection tank 120. In the non-cleaning position, the proximal end of the scraper 230 disengages from the surface to be cleaned, opening the passage from the front end of the brush assembly 200 to the agitator 220, thereby facilitating the agitator 220 to adsorb dirt particles on the surface to be cleaned in front of the brush assembly 200. In embodiments of this disclosure, this engagement can refer to pressurized contact.

[0119] Compared to the second portion 232, the first portion 231 is softer. The second portion 232 is used to transmit driving force, and the first portion 231 is used for selective contact with the floor. In the current embodiment, the first portion 231 is made of a soft material. The soft material may include thermoplastic elastomers and / or PVC. In other embodiments, it may also be made of one of the following materials: PVC, polyethylene, nylon, ABS, or rubber.

[0120] Figure 6 This is a partial structural schematic diagram of a floor brush assembly according to one embodiment of the present disclosure.

[0121] In some preferred examples, such as Figure 6 As shown, the length of the scraper 230 measured approximately parallel to the axis of the mixer 220 is greater than the length of the mixer 220 measured along its axis. In other embodiments, the length of the scraper 230 measured approximately parallel to the axis of the mixer 220 may be approximately the same as, or less than, the length of the mixer 220 measured along its axis.

[0122] See again Figure 6 The scraper 230 includes a first lateral end 23A and a second lateral end 23B. The agitator 220 includes a first lateral end 22A and a second lateral end 22B. The first lateral ends 23A and 23B of the scraper 230 are closer to the first side 213 and the second side 214 of the housing 210 than the first lateral ends 22A and 22B of the agitator 220. However, in other embodiments, the first lateral end 23A of the scraper 230 may be closer to the first side 213 of the housing 210 than the first lateral end 22A of the agitator 220, while the second lateral end 23B of the scraper 230 may be farther or the same distance from the second side 214 of the housing 210 compared to the second lateral end 22B of the agitator 220.

[0123] Figure 7 This is a schematic diagram of the structure of the adjustment component 250 according to one embodiment of the present disclosure. Figure 8 This is a schematic diagram of a state of the adjustment component 250 according to one embodiment of the present disclosure.

[0124] like Figure 7 and Figure 8 As shown, the floor brush assembly 200 of this disclosure may include an adjustment assembly 250, which is connected to the scraper 230. The adjustment assembly 250 applies an adjustment action in the lateral direction on the housing 210, causing the scraper 230 to switch between a cleaning position and a non-cleaning position. When the scraper 230 is in the cleaning position, the scraper 230 engages with the surface to be cleaned. When the scraper 230 is in the non-cleaning position, the scraper 230 disengages from the surface to be cleaned.

[0125] Specifically, the floor brush assembly 200 is equipped with a movable adjustment assembly 250. For example... Figure 8 As shown, the adjustment assembly 250 of this disclosure may include an actuator 251, a sliding frame 252, and a connecting rod 253. The actuator 251 is disposed in the housing 210; one end of the sliding frame 252 is pivotally connected to the actuator 251; one end of the connecting rod 253 is pivotally connected to the other end of the sliding frame 252; the other end of the connecting rod 253 is pivotally connected to the scraper 230; wherein, the actuator 251 is configured to drive the sliding frame 252 to reciprocate laterally relative to the housing 210, such that the connecting rod 253 switches between an inclined state and an upright state relative to the housing 210.

[0126] In other words, the adjustment assembly 250 includes a cooperating actuator 251 and a sliding frame 252, which are pivotally connected such that the actuator 251 can actuate at least a portion of the sliding frame 252, causing the sliding frame 252 to reciprocate laterally along the housing 210. At least one link 253 is pivotally connected to the sliding frame 252, the other end of which is pivotally connected to the scraper 230, connecting the adjustment assembly 250 to the scraper 230. Thus, the actuator 251 is configured to drive the sliding frame 252 to reciprocate laterally relative to the housing 210, such that the link 253 switches between an inclined and an upright position relative to the housing 210.

[0127] Specifically, actuator 251 includes a connector 2511 pivotally connected to slide frame 252. Connector 2511, under the action of a power unit (e.g., a servo motor), can reciprocate along a trajectory T between a first position A1 and a second position A2 in the lateral direction of housing 210, thereby driving slide frame 252 to reciprocate laterally within housing 210. A first end of connecting rod 253 is pivotally connected to the main body of slide frame 252, and a second end of connecting rod 253 opposite to the first end is pivotally connected to the second portion 232 of scraper 230.

[0128] In one example, as shown in the figure, in order to better achieve the purpose of this disclosure, the trajectory T of the connector 2511 between the first position A1 and the second position A2 presents an approximately arc shape, with the arc protruding in the direction in front of the floor brush assembly 200, so that the connector 2511 has a displacement in the working direction of the floor brush assembly 200 when driving the sliding frame 252, thereby preventing the connecting rod 253 from jamming and causing the drive structure to fail.

[0129] like Figure 9 As shown, the free end of the connector 2511 of this disclosure has an elongated groove. For example... Figure 11As shown, a cylindrical protrusion is provided on the transmission arm 2521. The cylindrical protrusion is rotatably and slidably disposed in the elongated groove of the connector 2511. Thus, in the front-back direction, the sliding frame 252 can generate a certain movement relative to the actuator 251 in the front-back direction, so that the transmission arm 2521 can swing freely without being jammed.

[0130] Figure 9 This is a schematic diagram of the actuator according to one embodiment of the present disclosure. Figure 10 This is a schematic diagram of the working principle of an actuator according to one embodiment of the present disclosure. Figure 11 This is a schematic diagram of the structure of a sliding frame according to one embodiment of the present disclosure. Figure 12 This is a schematic diagram of another state of the regulating component according to one embodiment of the present disclosure.

[0131] like Figure 10 As shown, when the connector 2511 drives the sliding frame 252 between the first position A1 and the second position A2, so that the sliding frame 252 is driven to reciprocate laterally along the housing 210, both the first and second ends of the connecting rod 253 are freely rotatable. Specifically, as above, the scraper 230 extends laterally between the first side 213 and the second side 214 of the housing 210, that is, the first side 213 and the second side 214 of the housing 210 basically define the movement path of the scraper 230 and restrict its degree of freedom of movement in the lateral direction relative to the housing 210. Therefore, when the sliding frame 252 is driven to reciprocate laterally along the housing 210, the lateral component of the force transmitted to the scraper 230 via the connecting rod 253 is counteracted by the opposing force of the first side 213 or the second side 214 on the scraper 230, while the longitudinal component of the force transmitted to the scraper 230 via the connecting rod 253 can drive the scraper 230 to move along the movement path defined by the first side 213 and the second side 214, thereby adjusting the position of the scraper 230. During this process, the connecting rod 253 can be in an inclined state relative to the housing 210 (e.g., Figure 8 ) and upright position (such as Figure 12 Switch between )

[0132] In some other examples, to optimize the space utilization efficiency of the floor brush assembly 200, the actuator 251 is set off-center from the centerline of the housing 210.

[0133] In some other instances, the sliding frame 252 may also include a drive arm 2521 and a frame 2522, one end of the drive arm 2521 being pivotally connected to the actuator 251, and the other end of the drive arm 2521 being disposed off-center from the centerline of the frame 2522.

[0134] In some instances, the frame 2522 includes an extension 25221 for connection to the drive arm 2521, and a connecting portion 25222 for connection to the scraper 230 (or linkage). The extension 25221 extends on the connecting portion 25222 in a direction generally parallel to the inner wall of the housing 210, and the connecting portion 25222 extends longitudinally in a direction generally perpendicular to the ground. In an embodiment, the connecting portion 25222 extends laterally linearly, generally parallel to the axis of the drive shaft of the agitator 220, and is positioned substantially parallel to the first portion 231 of the scraper 230.

[0135] The adjustment assembly 250 can selectively move between a non-cleaning position and a cleaning position. The adjustment assembly 250 can be connected to a controller and operate under its control. In the cleaning position, the controller sends a drive signal to the adjustment assembly 250. The adjustment assembly 250 controls the proximal end of the scraper 230 to move towards the surface to be cleaned so that the final scraper 230 engages with the surface. Excess material on the floor is collected and recycled by adjusting the direction of movement of the floor brush assembly 200 (e.g., moving backward).

[0136] More specifically, the high-speed rotating agitator 220 generates airflow that tends to draw dirt and debris from the floor into the suction inlet 240. Therefore, as the floor brush assembly 200 moves forward, the scraper 230, engaged with the floor, actually interferes with efficient floor cleaning. Thus, in some instances, as the floor brush assembly 200 moves forward, the controller sends a drive signal to the adjustment assembly 250, which controls the proximal end of the scraper 230 to move away from the surface to be cleaned, so that the scraper 230 eventually disengages from the surface.

[0137] In some other examples, the actuation of the adjustment component 250 can be achieved via a switch, which the user can manually operate to control the operation of the adjustment component 250. In some cases, the actuation of the adjustment component 250 is linearly controlled, allowing the user to control the actuation amplitude of the adjustment component 250 according to the actual working conditions, thereby controlling the distance between the scraper 230 and the surface to be cleaned.

[0138] In cases of stubborn stains where the scraper 230 needs to engage with the floor and the brush assembly 200 needs to move back and forth, the controller can improve floor cleaning efficiency by slowing down or interrupting the drive of the agitator 220, thus eliminating these airflows. For example, when the brush assembly 200 is equipped with a separate agitator drive motor, the controller can simply reduce or interrupt the power supply to that agitator drive motor when the adjustment assembly 250 engages the controller in the cleaning position.

[0139] The actuator 251 includes at least a connector 2511 for pivoting engagement of the free end of the transmission arm 2521, the connector 2511 being driven to reciprocate along a trajectory between a first position and a second position in the transverse direction of the housing 210.

[0140] Figure 15 This is a schematic diagram of the structure of a floor brush assembly according to another embodiment of the present disclosure (not the cleaning position). Figure 16 This is a schematic diagram of the structure of a floor brush assembly according to another embodiment of the present disclosure (cleaning position). Figure 17 This is a schematic diagram of the scraper according to another embodiment of the present disclosure. Figure 18 This is a structural schematic diagram of a scraper according to another embodiment of the present disclosure from another angle.

[0141] In another embodiment of the floor brush assembly, the floor brush assembly differs from the floor brush assembly described above only in the structure of the scraper 230.

[0142] Specifically, the scraper 230 of this embodiment is provided with a suction port 235, which is used to absorb liquid from the surface to be cleaned. The liquid absorbed by the scraper 230 can be transported to the fluid channel 216. Thus, after the scraper 230 scrapes away the water on the surface to be cleaned and collects it together, the liquid can be sucked into the fluid channel 216 through the suction port 235, thereby reducing the amount of liquid residue on the surface to be cleaned and improving the cleaning effect.

[0143] In this disclosure, at least a portion of the fluid channel 216 can be formed by a hole structure on the housing. In addition, other portions of the fluid channel 216 can be formed by components such as hoses connected to the hole structure. In this case, the suction port 240 can be formed as the starting point of the fluid channel 216.

[0144] Multiple suction ports 235 are provided along the length of the scraper 230, and these suction ports 235 are all located on the lower end face of the scraper 230. Thus, the liquid on the surface to be cleaned can be removed as quickly as possible through multiple suction ports 235, and by providing multiple suction ports 235, the amount of liquid residue on the surface to be cleaned will also be reduced.

[0145] The scraper 230 includes a connection interface 236, which communicates with the suction port 235 and is connected to the fluid channel 216 via a connection pipe 260. Additionally, the connection interface 236 is connected to the suction port 235 via a pipe disposed inside the scraper 230.

[0146] Based on the above structure, the floor brush assembly disclosed herein can greatly reduce the amount of water residue on the surface to be cleaned during use, and will not have the problem that water stains remain on the surface to be cleaned after the surface cleaning equipment in the prior art has stopped cleaning.

[0147] This disclosure also provides a surface cleaning device including the aforementioned floor brush assembly 200. In use, after cleaning the surface to be cleaned, the surface cleaning device can be controlled to retract a certain distance, thereby removing water stains (e.g., water stains remaining on the roller brush) from the surface to be cleaned. Therefore, the surface cleaning device of this disclosure has stronger cleaning ability and better cleaning effect, and can also avoid the impact of water accumulation on wooden floors, resulting in a smoother floor surface.
