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] However, when faced with stubborn stains, this type of cleaning equipment requires the roller brush to repeatedly rub against the stubborn stains in order to remove them. Therefore, removing stubborn stains often takes a long time.

[0005] To address the problem of removing stubborn stains, existing surface cleaning equipment provides steam to the surface to be cleaned. The steam softens the stubborn stains and causes them to adhere to hot water, thus reducing the cleaning time.

[0006] In existing surface cleaning equipment, the distance between the steam inlet and the surface to be cleaned is fixed. When the steam inlet is too far from the ground, the temperature of the steam drops significantly when it reaches the ground. If the steam inlet is too close to the ground, it can easily block dirt from being sucked into the suction port. Utility Model Content

[0051] 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.

[0052] 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.

[0053] Figure 1 This is a schematic diagram of the structure of a surface cleaning device according to one embodiment of the present disclosure.

[0054] like Figure 1 As shown, this disclosure provides a surface cleaning apparatus capable of cleaning a surface to be cleaned. In a preferred embodiment, the surface cleaning apparatus can be a wet vacuum cleaner, which is capable of performing wet cleaning of the surface to be cleaned.

[0055] The surface cleaning device includes a body 100 and a floor brush assembly 200, wherein the body 100 is pivotally connected to the floor brush assembly 200. 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 to pivot 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 embodiments, the pivotal 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 within the footprint of the floor brush assembly 200. This allows the surface cleaning device to be stored in an upright position. Thus, the surface cleaning device of this disclosure can be supported by the floor brush assembly 200 during use and / or in its storage position.

[0056] 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 may be a handheld vacuum cleaner. In this case, the surface cleaning device includes a handle 300 for the 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.

[0057] 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.

[0058] 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.

[0059] 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 roller brush 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.

[0060] 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, 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.

[0061] Figure 2 This is a schematic diagram of the structure of a floor brush assembly according to one embodiment of the present disclosure. Figure 3 This is a structural schematic diagram of another state of the floor brush assembly according to one embodiment of the present disclosure.

[0062] like Figure 2 and Figure 3 As shown, the floor brush assembly 200 may include a housing 210, a roller brush 220, a steam supply assembly 230, and an adjustment assembly 250. When the surface cleaning device of this disclosure is in operation, the housing 210 is movable along the surface to be cleaned. In one specific embodiment, the housing 210 may include a front side and a rear side; moreover, the housing 210 may also include a first side and a second side extending between the front and rear sides. In this case, the front side, the rear side, and the first and second sides define a perimeter that defines the floor area occupied by the floor brush assembly 200.

[0063] In this disclosure, the first side and the second side can be two sides in the left-right direction (i.e., the lateral direction). For example, the first side can be the right side and the second side can be the left side.

[0064] The floor brush assembly 200 also includes a roller brush 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 back-and-forth direction of movement of the cleaner during use.

[0065] The floor-facing surface of housing 210 extends between a front side, a rear side, and a first side and a second side. 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 steam supply assembly 230. The steam supply assembly 230 is located in front of the roller brush 220. The floor-facing surface includes an intake port through which air carrying dirt and dirty cleaning fluid can be received. The chamber of the floor brush assembly 200 is at least partially defined by a rear chamber wall. The rear chamber wall defines the intake port. The intake port 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 roller brush 220 can be exposed.

[0066] Thus, the roller brush 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, thereby allowing dirt and cleaning liquids detached from the roller brush 220 to be smoothly collected against the rear cavity wall and enter the suction port.

[0067] The steam supply assembly 230 of this disclosure is disposed in the housing 210 and located in front of the roller brush 220; in other words, the steam supply assembly 230 of this disclosure can be formed as the front end of the floor brush assembly 200.

[0068] Furthermore, the steam supply assembly 230 is attached to the floor-facing surface of the housing 210. The steam supply assembly 230 extends laterally between the first and second sides of the housing 210 (but not entirely to each side, although it could), for selectively wiping or contacting the surface to be cleaned. In an embodiment, the steam supply assembly 230 extends substantially linearly between the first and second sides.

[0069] The first and second sides of the housing 210 define the trajectory path for the vertical movement of the steam supply assembly 230. For example, the first and second sides of the housing 210 can guide the vertical movement of the steam supply assembly 230.

[0070] It should also be noted that when the steam supply component 230 of this disclosure moves relative to the housing 210, the steam supply component 230 can rotate a certain angle relative to the housing 210. Therefore, during the up-and-down movement, the steam supply component 230 of this disclosure can also move closer to and further away from the roller brush 220. Accordingly, the movement trajectory of the lower end of the steam supply component 230 of this disclosure can be arc-shaped.

[0071] Figure 4 This is a schematic diagram of the structure of a steam supply assembly according to one embodiment of the present disclosure.

[0072] like Figure 4As shown, the steam supply assembly 230 of this disclosure includes a nozzle 231 and a plate component 232. The nozzle 231 is used to supply steam to the surface to be cleaned. In this case, the steam can be high-temperature steam. In another embodiment, the nozzle 231 can be used to supply a cleaning liquid to the surface to be cleaned, which can also be a high-temperature cleaning liquid.

[0073] Nozzles 231 extend on plate member 232 in a direction generally perpendicular to the ground, and multiple nozzles 231 are provided, which are evenly distributed along the length direction (i.e., the transverse direction) of plate member 232.

[0074] The plate component 232 is used to connect the nozzle 231. In one embodiment, the plate component 232 can be integrally formed with the nozzle 231. Of course, the nozzle 231 can also be formed as a separate component, which can be fixed to the plate component 232 by means of fastening such as threaded connection.

[0075] The plate component 232 also extends generally linearly between the first and second sides. In this embodiment, the plate component 232 extends generally parallel to the axis of the roller brush 220. The plate component 232 is further away from the floor surface to be cleaned than the nozzle 231.

[0076] The cross-sectional shape / profile of the plate member 232, when viewed in a direction perpendicular or substantially perpendicular to the axis of the roller brush 220, remains substantially constant along its length. However, in other embodiments, the plate member 232 may be substantially rectangular in a side view cross-section perpendicular or substantially perpendicular to the axis of the roller brush 220.

[0077] The upper end of the plate component 232 forms the free end of the steam supply assembly 230, which is connected to the adjustment component 250 (described in detail below). Under the action of the adjustment component 250, the steam supply assembly 230 is moved between a working position and a non-working position by driving the plate component 232. When in the working position, the steam supply assembly 230 has a first distance from the surface to be cleaned; when in the non-working position, the steam supply assembly 230 has a second distance from the surface to be cleaned. The first distance is smaller than the second distance. Therefore, when the steam supply assembly 230 is in the working position, it can supply steam to the surface to be cleaned. This steam can reach the surface to be cleaned in a short time to soften stubborn stains, thereby enabling the surface cleaning equipment to efficiently remove these stubborn stains. When the steam supply assembly 230 is in the non-working position, it can move away from the surface to be cleaned, thus not blocking dirt and solving the technical problems mentioned in the background art.

[0078] Although not shown in the accompanying drawings, those skilled in the art should know that a gas flow path is formed inside the plate component 232, and an interface component can be provided at the inlet of the gas flow path. The interface component can be connected to a steam generator so that the steam generated by the steam generator can be input into the interior of the plate component 232 and discharged through the nozzle 231 installed at the outlet of the gas flow path.

[0079] Figure 5 This is a schematic diagram of the structure of the adjustment component of a floor brush assembly according to one embodiment of the present disclosure. Figure 6 This is a schematic diagram of the actuator and track according to one embodiment of the present disclosure.

[0080] like Figures 2 to 6 As shown, the adjustment component 250 of this disclosure is connected to the steam supply component 230. The adjustment component 250 applies adjustment in the lateral and longitudinal directions on the housing 210, causing the steam supply component 230 to swing between a working position and a non-working position. When the steam supply component 230 is in the working position, the steam supply component 230 has a first distance from the surface to be cleaned. When the steam supply component 230 is in the non-working position, the steam supply component 230 has a second distance from the surface to be cleaned, wherein the first distance is less than the second distance.

[0081] Therefore, the steam supply component 230 of this disclosure can be released and retracted. Thus, when the user needs the assistance of the steam supply component 230 in the process of cleaning the surface to be cleaned, the user can release the steam supply component 230 and supply steam to the surface to be cleaned through the steam supply component 230.

[0082] When the user does not need the steam supply component 230, the steam supply component 230 can be retracted, thereby preventing the steam supply component 230 from affecting the normal cleaning process and also extending the service life of the steam supply component 230.

[0083] In one specific embodiment, the adjustment assembly 250 may include components such as an actuator 251, a sliding frame 252, and a track 253. The actuator 251 is disposed in the housing 210; a first end of the sliding frame 252 is pivotally connected to the actuator 251, and a second end opposite to the first end is pivotally connected to the steam supply assembly 230; the track 253 is disposed in the housing 210 and extends vertically along the housing 210; the steam supply assembly 230 is configured to slide vertically along the track 253 under the drive of the sliding frame 252, and to oscillate relative to the track 253 during the sliding process.

[0084] Therefore, the regulating component 250 of this disclosure can conveniently regulate the position of the steam supply component 230, and make the steam supply component 230 either in a working position or in a non-working position.

[0085] 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 longitudinally (i.e., reciprocate in the front-to-back direction) along the housing 210. In a preferred embodiment, the movement of the sliding frame 252 in the front-to-back direction can be a movement within a plane, in which case the sliding frame 252 can be guided by the housing 210.

[0086] In a preferred embodiment, the actuator 251 is disposed off-center from the housing 210, thereby allowing the actuator 251 of this disclosure to be conveniently arranged on the housing 210, and the actuator 251 also facilitates the movement of the sliding frame 252.

[0087] Specifically, the actuator 251 of this disclosure includes a connector 2511 pivotally connected to the slide frame 252. The connector 2511 can reciprocate along a trajectory between a first position and a second position in the longitudinal direction of a housing 210 under the action of a power device (e.g., a servo motor) to drive the slide frame 252 to reciprocate longitudinally within the housing 210.

[0088] In other words, the connector 2511 is configured to be rotatably driven at its first end, such that the second end of the connector 2511, opposite the first end, can reciprocate along a trajectory between a first position and a second position. In a preferred embodiment, this trajectory is arc-shaped, with the apex of the arc facing the lateral side of the floor brush assembly 200. Thus, a small angular change in the connector 2511 of this disclosure can cause a large longitudinal displacement in the slide 252, and correspondingly, the actuator 251 of this disclosure can drive the slide 252 to move more rapidly.

[0089] See again Figure 6 The other end of the connector 2511 disclosed herein has a cylindrical protrusion. Meanwhile, as... Figure 5 As shown, the sliding frame 252 has an elongated groove. The length direction of the elongated groove can be the transverse direction. Thus, the cylindrical protrusion can slide in the elongated groove and be in different positions in the elongated groove, so as to drive the sliding frame 252 to move in the longitudinal direction by the swing of the connector 2511.

[0090] When the connector 2511 drives the sliding frame 252 between the first position and the second position, so that the sliding frame 252 is driven to reciprocate longitudinally along the housing 210, it can push or pull the steam supply assembly 230 to move, thereby enabling the steam supply assembly 230 to be in the working position or the non-working position.

[0091] Specifically, such as Figure 6 As shown, the track 253 of this disclosure is disposed in the vertical direction on at least one of the first and second sides of the housing 210. In a preferred embodiment, the track 253 is disposed on both the first and second sides of the housing 210, and the two tracks 253 are disposed on two opposite surfaces of the first and second sides of the housing 210.

[0092] In one specific embodiment, the track 253 can be formed as a groove structure on two opposing surfaces of the housing 210 on the first and second sides. Alternatively, the groove structure can also be formed in the region between protrusions on the two opposing surfaces of the first and second sides.

[0093] In this disclosure, the track 253 preferably extends in a vertical direction. In other words, the track 253 extends in a direction perpendicular to the surface to be cleaned, in which case the track 253 is formed in a generally straight shape. In another embodiment, the track 253 may also be formed in a curved shape.

[0094] The plate component 232 of this disclosure is pivotally connected to the second end of the sliding frame 252. A slider 2321 is provided on the side of the plate component 232 corresponding to the track 253. The slider 2321 is configured to cooperate with the track 253 and its sliding trajectory is defined by the track 253. Specifically, the slider 2321 of this disclosure is formed as a cylindrical protrusion, so that the slider 2321 can not only slide within the track 253, but also rotate relative to the track 253. At this time, the steam supply assembly 230 as a whole can rotate relative to the housing.

[0095] The regulating component 250 can selectively move between a non-operating position and an operating position. The regulating component 250 can be connected to a controller and operate under the controller's control. In the operating position, the controller sends a drive signal to the regulating component 250 to cause the steam supply component 230 to move.

[0096] In some other examples, the actuation of the regulating component 250 can be achieved via a switch, which the user can manually operate to control the operation of the regulating component 250. In some cases, the actuation of the regulating component 250 is linearly controlled, allowing the user to control the actuation amplitude of the regulating component 250 according to the actual operating conditions, thereby controlling the distance between the steam supply component 230 and the surface to be cleaned.
