[0041] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0042] In the description of the embodiments of this disclosure, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this disclosure. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] Current handheld floor scrubbers remove dirt from surfaces by spraying water onto the roller brush and using the brush's rotation. However, many users have carpets or rugs at home, and when cleaning these items, the water on the roller brush can wet or soil them, which is undesirable.

[0044] In related technologies, to solve the above problems, the motor of the floor scrubber is usually removed and the entire vacuuming kit is replaced, thereby switching the cleaning mode of the floor scrubber from wet cleaning to dry cleaning. This method is cumbersome to operate, has complicated parts, increases the user's operating costs, affects the user experience, and is difficult to meet the user's needs.

[0045] This disclosure provides a floor brush device and cleaning equipment to solve the shortcomings of the prior art, which usually involves removing the motor of the floor scrubber and replacing it with a complete set of vacuuming kits to switch the cleaning mode of the floor scrubber from wet cleaning to dry cleaning. This method is cumbersome to operate, has complicated accessories, increases the user's operating costs, affects the user experience, and fails to meet the user's needs.

[0046] The present disclosure will now be described in detail with reference to specific embodiments.

[0047] In some specific embodiments of this disclosure, as shown in Figures 1 to 12, this solution provides a floor brush device, including: a housing 10; a roller brush 20 connected to the housing 10; a wheel 30 connected to the housing 10 and spaced apart from the roller brush 20 along a first direction N, where the first direction N is the direction of movement of the floor brush device; an auxiliary wheel assembly 40 connected to the housing 10 and located between the roller brush 20 and the wheel 30, the auxiliary wheel assembly 40 being provided with an auxiliary wheel 41; and a wringer assembly 50 connected to the housing 10 and located between the roller brush 20 and the wheel 30; wherein the auxiliary wheel assembly 40 and the wringer assembly 50 are capable of relative movement, adjusting the support height of the auxiliary wheel assembly 40 and the distance between the wringer assembly 50 and the roller brush 20 to meet the needs of different working scenarios.

[0048] It should be noted that the work scenario includes at least a first cleaning mode and a second cleaning mode, which are distinguished by the ground material. The hardness of the ground material to be cleaned in the first cleaning mode is greater than that in the second cleaning mode.

[0049] According to one embodiment of this disclosure, during the switching of different working scenarios, the support height of the auxiliary wheel assembly 40 gradually increases, and the distance between the water squeezing scraper assembly 50 and the roller brush 20 gradually increases or decreases.

[0050] Specifically, this embodiment provides an implementation method for the auxiliary wheel assembly 40 and the water squeezing scraper assembly 50 during the switching of different working scenarios.

[0051] According to one embodiment of this disclosure, during the switching of different working scenarios, the support height of the auxiliary wheel assembly 40 gradually decreases, and the distance between the water squeezing scraper assembly 50 and the roller brush 20 gradually increases or decreases.

[0052] Specifically, this embodiment provides another implementation method for the auxiliary wheel assembly 40 and the water squeezing scraper assembly 50 during the switching process of different working scenarios.

[0053] In some specific embodiments of this disclosure, as shown in Figures 1 to 12, this solution provides a floor brush device, including: a housing 10; a roller brush 20 connected to the housing 10; a wheel 30 connected to the housing 10 and spaced apart from the roller brush 20 along a first direction N, where the first direction N is the direction of movement of the floor brush device; an auxiliary wheel assembly 40 connected to the housing 10 and located between the roller brush 20 and the wheel 30, the auxiliary wheel assembly 40 being provided with an auxiliary wheel 41; and a wringer assembly 50 connected to the housing 10 and located between the roller brush 20 and the wheel 30. Between 30; a switching element 60, which is connected to the housing 10 and can reciprocate, is connected to the auxiliary wheel assembly 40 and the squeezing scraper assembly 50 respectively. The relative positions between the auxiliary wheel assembly 40 and the roller brush 20, and between the squeezing scraper assembly 50 and the roller brush 20, change with the reciprocating motion of the switching element 60; wherein, the distance between the rotation center line of the auxiliary wheel 41 and the rotation center line of the roller brush 20 is the first length; the distance between the rotation center line of the roller brush 20 and the rotation center line of the wheel body 30 is the second length; the ratio of the first length and the second length is between 1 / 10 and 1 / 2.

[0054] It should be noted that, as shown in Figures 1 to 12, this disclosure does not describe in detail the specific connection relationship of the housing 10, the roller brush 20, the wheel body 30, the auxiliary wheel assembly 40, and the wringer assembly 50. In order to save space, this disclosure does not make too many elaborations. The setting position of the above parts can be referred to the relevant settings in the field. In the home appliance field, especially in product lines such as floor scrubbers and sweepers, there are similar main structure designs. Therefore, the description of the relative positions of the housing 10, the roller brush 20, the wheel body 30, the auxiliary wheel assembly 40, and the wringer assembly 50 in this disclosure is clear.

[0055] Furthermore, the distance between the rotation center line of the auxiliary wheel 41 and the rotation center line of the roller brush 20, and the distance between the rotation center line of the roller brush 20 and the rotation center line of the wheel body 30 are set to a corresponding proportional relationship, which helps to ensure that the auxiliary wheel 41 can effectively provide support.

[0056] In some embodiments, as shown in Figures 1 to 3, the roller brush 20 is rotatably disposed at the bottom of the housing 10, the switching member 60 is slidably disposed on the housing 10, and the squeezing scraper assembly 50 and the auxiliary wheel assembly 40 are disposed on the housing 10. During the adjustment of the relative position with respect to the roller brush 20, the squeezing scraper assembly 50 and the auxiliary wheel assembly 40 rotate or slide, or a combination of rotation and sliding, to achieve the change of position of the squeezing scraper assembly 50 and the auxiliary wheel assembly 40. When the switching member 60 is at the two ends of the reciprocating motion, the distances between the rotation center line of the auxiliary wheel 41 and the rotation center line of the roller brush 20 are D2 and D2', respectively, and the distance between the rotation center line of the roller brush 20 and the rotation center line of the wheel body 30 is D1. The ratios of D2 and D2' to D1 need to fall between 1 / 10 and 1 / 2.

[0057] In some embodiments, the switching member 60 is capable of reciprocating along the second direction M, and the switching member 60 is connected to the auxiliary wheel assembly 40 and the squeezing scraper assembly 50 respectively. The relative positions between the auxiliary wheel assembly 40 and the roller brush 20, and between the squeezing scraper assembly 50 and the roller brush 20, change with the reciprocating motion of the switching member 60. The second direction M and the first direction N are perpendicular to each other.

[0058] According to one embodiment of this disclosure, the switching member 60 is provided with a first position and a second position during the reciprocating motion stroke.

[0059] Specifically, this embodiment provides an implementation of a first position and a second position of the switching member 60 in reciprocating motion.

[0060] It should be noted that the first position and the second position are two different positions of the switching component 60 on the reciprocating motion. They can be the endpoints of the reciprocating motion or any position in the middle of the reciprocating motion.

[0061] According to one embodiment of this disclosure, the wringer assembly 50 includes: a wringer body 51, which is movably connected to the housing 10, the movable connection including a rotatable connection or a sliding connection; when the switching member 60 is in a first position, the distance between the central axis of the wringer body 51 and the roller brush 20 is a first distance; when the switching member 60 is in a second position, the distance between the central axis of the wringer body 51 and the roller brush 20 is a second distance; wherein, the first distance is less than the second distance.

[0062] Specifically, this embodiment provides another implementation of the first and second positions of the switching element 60 in reciprocating motion.

[0063] According to one embodiment of this disclosure, when the switching member 60 is in the first position, the outer surfaces of the scraper body 51 and the roller brush 20 interfere with each other; when the switching member 60 is in the second position, the outer surfaces of the scraper body 51 and the roller brush 20 interfere with each other or there is a gap.

[0064] Specifically, this embodiment provides an implementation in which the switching element 60 is located in the first position and the second position respectively. By setting the switching element 60, the distance between the auxiliary wheel assembly 40 and the squeegee assembly 50 and the roller brush 20 can be adjusted, so that the floor brush device can switch between different cleaning modes according to the floor material when cleaning different floor materials.

[0065] According to one embodiment of this disclosure, when the switching member 60 is in the first position, the distance between the roller brush 20 and the surface to be cleaned is less than the distance between the auxiliary wheel 41 and the surface to be cleaned; when the switching member 60 is in the second position, the distance between the roller brush 20 and the surface to be cleaned is greater than the distance between the auxiliary wheel 41 and the surface to be cleaned.

[0066] Specifically, this embodiment provides another implementation in which the switching member 60 is located in the first position and the second position respectively. When the switching member 60 is located in the second position, the distance between the roller brush 20 and the surface to be cleaned is greater than the distance between the auxiliary wheel 41 and the surface to be cleaned, so that the auxiliary wheel 41 can support the housing 10.

[0067] Furthermore, adjusting the distance between the wringer assembly 50 and the roller brush 20 mainly involves adjusting the amount of interference between the wringer assembly 50 and the roller brush 20, or creating a gap between the wringer assembly 50 and the roller brush 20. This reduces the resistance experienced by the roller brush 20 from the wringer assembly 50 when cleaning soft surfaces, and provides additional support through the auxiliary wheel assembly 40, which also reduces the resistance of the soft surface when the roller brush 20 rotates.

[0068] In some embodiments of this disclosure, the switching member 60 is provided with a first guide groove 61, the extension direction of the first guide groove 61 forming an angle with the movement direction of the switching member 60; the auxiliary wheel assembly 40 further includes: an auxiliary bracket 42 and a guide post 43; the auxiliary bracket 42 is movably connected to the housing 10, the movable connection including a rotational connection or a sliding connection; one end of the auxiliary bracket 42 is connected to the auxiliary wheel 41, and the other end of the auxiliary bracket 42 is connected to the guide post 43; the guide post 43 is slidably engaged with the first guide groove 61.

[0069] Specifically, this embodiment provides an implementation of a switching member 60 and an auxiliary wheel assembly 40. This disclosure provides a first guide groove 61 on the switching member 60, and the first guide groove 61 is an inclined groove structure, that is, the extension direction of the first guide groove 61 forms an angle with the movement direction of the switching member 60. The guide post 43 in the auxiliary wheel assembly 40 slides with the first guide groove 61, so that during the movement of the switching member 60, the guide post 43 can slide under the action of the first guide groove 61, thereby driving the movement of the auxiliary support 42, realizing the adjustment of the relative position between the auxiliary wheel assembly 40 and the roller brush 20, that is, the adjustment of the relative position between the auxiliary support 42 and the roller brush 20.

[0070] In some embodiments, during the process of switching from the first cleaning mode to the second cleaning mode, the guide post 43 slides under the guidance of the first guide groove 61 to adjust the relative position between the auxiliary support 42 and the roller brush 20.

[0071] In some embodiments of this disclosure, the switching member 60 is provided with a second guide groove 62, which extends in a direction perpendicular to the ground, and the sidewall of the second guide groove 62 forms a first guide surface, which forms an angle with the movement direction of the switching member 60; the wringer assembly 50 includes a guide block 52, which is disposed on the wringer body 51 and is inserted into the second guide groove 62, and the sidewall of the guide block 52 forms a second guide surface, which cooperates with the first guide surface.

[0072] Specifically, this embodiment provides an implementation of a switching component 60 and a squeezing scraper assembly 50. By providing a second guide groove 62 on the switching component 60 and cooperating with the guide block 52 provided on the scraper body 51, the relative position between the scraper body 51 and the roller brush 20 can be adjusted during the movement of the switching component 60, that is, the relative position between the squeezing scraper assembly 50 and the roller brush 20 can be adjusted.

[0073] It should be noted that, as shown in Figures 1 to 5, the change in the distance between the squeezing scraper assembly 50 and the roller brush 20 specifically refers to the change in the overlapping area of ​​the squeezing scraper assembly 50 and the roller brush 20 when projected along the axial direction of the roller brush 20. The closer the squeezing scraper assembly 50 and the roller brush 20 are, the larger the overlapping area of ​​the squeezing scraper assembly 50 and the roller brush 20, and the greater the interference between the squeezing scraper assembly 50 and the roller brush 20. The farther the distance between the squeezing scraper assembly 50 and the roller brush 20 is, the smaller the overlapping area of ​​the squeezing scraper assembly 50 and the roller brush 20, and the smaller the interference between the squeezing scraper assembly 50 and the roller brush 20. When there is no overlapping area between the squeezing scraper assembly 50 and the roller brush 20, there is a gap between the squeezing scraper assembly 50 and the roller brush 20.

[0074] In some embodiments of this disclosure, the wringer assembly 50 further includes an elastic portion 54, which is disposed on the side of the wringer body 51 facing the wheel 30 and abuts against the partition 13 disposed inside the housing 10, for providing an elastic restoring force to the wringer body 51.

[0075] Specifically, this embodiment provides an implementation of a squeezing blade assembly 50. By providing an elastic part 54 on the blade body 51, the blade body 51 can obtain different restoring forces during movement, so as to ensure the amount of interference or gap between the blade body 51 and the roller brush 20.

[0076] In some embodiments, as shown in Figures 1 to 5, the wringer assembly 50 further includes a wringer 55 and a water distributor 56. The wringer body 51 of the wringer 55 is provided with an elastic part 54. One end of the elastic part 54 is connected to the wringer body 51, and the other end abuts against the partition 13 provided in the bottom shell. When the wringer body 51 is switched from the position furthest from the roller brush 20 to the position closest to the roller brush 20 by the switching member 60, the wringer body 51 can be smoothly reset.

[0077] In some embodiments, the elastic part 54 is an elastic element such as a spring.

[0078] In some embodiments of this disclosure, when the switching member 60 is in the first position, the elastic restoring force provided by the elastic part 54 to the scraper body 51 is between 5 and 25 Newtons; when the switching member 60 is in the second position, the elastic restoring force provided by the elastic part 54 to the scraper body 51 is between 10 and 40 Newtons.

[0079] Specifically, this embodiment provides an implementation of the elastic restoring force provided by the elastic part 54 to the scraper body 51. The elastic part 54 ensures that the squeezing scraper assembly 50 maintains the pressure of the squeezing scraper 55 on the roller brush 20 when the distance between it and the roller brush 20 is minimal, thus ensuring that the pressure of the squeezing scraper 55 on the roller brush 20 is sufficient to squeeze out excess water or dirty water on the roller brush 20.

[0080] In some embodiments, when the wringer assembly 50 is furthest from the roller brush 20, the force applied by the elastic part 54 to the assembly of the wringer 55 causes the wringer body 51 to maintain its tendency to return to the position closest to the roller brush 20, so as to ensure that when the wringer body 51 is switched from the position furthest from the roller brush 20 to the position closest to the roller brush 20 by the switching member 60, the wringer body 51 can be smoothly reset.

[0081] In some embodiments, when the wringer assembly 50 is closest to the roller brush 20, the elastic portion 54 can provide an elastic restoring force between 5 and 25 Newtons.

[0082] In some embodiments, when the wringer assembly 50 is furthest from the roller brush 20, the elastic portion 54 provides an elastic restoring force between 10 and 40 Newtons.

[0083] In some embodiments of this disclosure, the floor brush device includes: a first cleaning mode and a second cleaning mode; when the floor brush device is in the first cleaning mode and in the second cleaning mode, the switching element 60 is respectively located at the two ends of the reciprocating motion.

[0084] Specifically, this embodiment provides an implementation of a first cleaning mode and a second cleaning mode. When the switching member 60 reaches one of the two endpoints of the reciprocating motion, the floor brush device is in the first cleaning mode or the second cleaning mode. The switching between the first cleaning mode and the second cleaning mode is realized through the reciprocating motion of the switching member 60, that is, the switching member 60 moving in the positive direction of the M direction or the negative direction of the M direction.

[0085] In some embodiments, when adjusting the first cleaning mode and the second cleaning mode by the reciprocating motion of the switching member 60, the switching member 60 can move in the positive direction of the M direction to switch from the first cleaning mode to the second cleaning mode, and move in the negative direction of the M direction to switch from the second mode back to the first cleaning mode.

[0086] Furthermore, when the switching member 60 moves in the positive direction of the M direction, it switches from the second mode to the first cleaning mode; when the switching member 60 moves in the negative direction of the M direction, it switches from the first cleaning mode to the second cleaning mode.

[0087] In some embodiments of this disclosure, the hardness of the surface material to be cleaned in the first cleaning mode is greater than that in the second cleaning mode.

[0088] Specifically, this embodiment provides an implementation method for determining the floor material hardness in a first cleaning mode and a second cleaning mode. The floors to be cleaned in the first and second cleaning modes differ; the floor hardness in the first cleaning mode is greater than that in the second cleaning mode. That is, the floor cleaned in the second cleaning mode is made of soft materials, such as carpets or floor mats. This disclosure, through the setting of the switching component 60, achieves adjustment of the relative position between the roller brush 20 and the wringer assembly 50, i.e., adjustment of the interference amount or gap, avoiding the need to replace the entire vacuum kit when cleaning soft floors.

[0089] In some embodiments of this disclosure, the auxiliary wheel assembly 40 further includes a first connecting portion 44, which is disposed on the auxiliary bracket 42 and cooperates with a second connecting portion 11 inside the housing 10 to adjust the relative position between the auxiliary bracket 42 and the roller brush 20; wherein the cooperation between the first connecting portion 44 and the second connecting portion 11 is a shaft hole cooperation or a sliding cooperation.

[0090] Specifically, this embodiment provides an implementation of a first connecting part 44 and a second connecting part 11. By providing a first connecting part 44 in the auxiliary wheel assembly 40 and a second connecting part 11 in the housing 10, the first connecting part 44 and the second connecting part 11 can be fitted together through a shaft hole or by sliding, thereby adjusting the relative position between the auxiliary wheel assembly 40 and the housing 10, for example, the auxiliary wheel assembly 40 can rotate or slide.

[0091] In some embodiments, as shown in Figures 1 to 5, the first connecting portion 44 on the auxiliary wheel assembly 40 is a rotating shaft or a hole-like structure, and the second connecting portion 11 on the housing 10 is a hole-like structure or a rotating shaft. The first connecting portion 44 and the second connecting portion 11 cooperate through a shaft hole to realize the rotation of the auxiliary wheel assembly 40. Alternatively, the first connecting portion 44 and the second connecting portion 11 can directly cooperate and rotate through sliding friction, or a bearing can be provided between the first connecting portion 44 and the second connecting portion 11 to rotate through rolling friction.

[0092] In some embodiments, the first connecting portion 44 on the auxiliary wheel assembly 40 is a slider-like structure, and the second connecting portion 11 on the housing 10 is a slide rail-like structure or a groove-like structure. The first connecting portion 44 and the second connecting portion 11 slide together to adjust the position of the auxiliary wheel assembly 40. Alternatively, the first connecting portion 44 can be a slide rail-like structure or a groove-like structure, and the second connecting portion 11 can be a slider-like structure.

[0093] In some embodiments of this disclosure, in the second cleaning mode, the force between the auxiliary wheel 41 and the ground is greater than the force between the roller brush 20 and the ground.

[0094] Specifically, this embodiment provides a second cleaning mode implementation. In the second cleaning mode, the auxiliary wheel 41 is closer to the ground than the roller brush 20, so that the force between the auxiliary wheel 41 and the ground is greater than the force between the roller brush 20 and the ground.

[0095] In some embodiments, as shown in Figures 1 to 4, the auxiliary wheel assembly 40 includes an auxiliary wheel 41, which is rotatably mounted on the auxiliary wheel 41 mounting portion via an axle. Specifically, the change in distance between the auxiliary wheel assembly 40 and the roller brush 20 in this disclosure refers to a change in the horizontal distance D2 between the rotation axis of the auxiliary wheel 41 and the rotation axis of the roller brush 20. Furthermore, the change in distance between the auxiliary wheel assembly 40 and the roller brush 20 can also refer to a change in the vertical distance D3 between the lower edge of the auxiliary wheel 41 and the lower edge of the roller brush 20, changing from D3 in Figure 2 to D3' in Figure 3. When the vertical distance of the auxiliary wheel assembly 40 changes, the auxiliary wheel assembly 40 will be closer to the ground relative to the roller brush 20, thereby providing more stable support.

[0096] In some embodiments, during the process of switching from the first cleaning mode to the second cleaning mode, the guide block 52 disengages from the second guide groove 62, thereby adjusting the relative position between the scraper body 51 and the roller brush 20.

[0097] In some embodiments, as shown in Figures 1 to 5, the mating point between the guide block 52 and the second guide groove 62 is a wedge-shaped structure, which facilitates the guide block 52 to disengage from the second guide groove 62. In order to make it easier for the guide block 52 to disengage from the second guide groove 62, the second guide groove 62 is provided with a slope-shaped structure that mates with the wedge-shaped structure. During the movement of the switching member 60, the second guide groove 62 pushes the guide block 52 out of the second guide groove 62. After the guide block 52 disengages from the second guide groove 62, it causes the scraper body 51 to change position, such as rotating or sliding, thereby adjusting the relative position between the squeezing scraper assembly 50 and the roller brush 20.

[0098] In some embodiments of this disclosure, the wringer assembly 50 further includes a third connecting part 53, which is disposed on the wringer body 51 and cooperates with a fourth connecting part 12 in the housing 10 to adjust the relative position between the wringer body 51 and the roller brush 20; wherein the cooperation between the third connecting part 53 and the fourth connecting part 12 is a shaft hole cooperation or a sliding cooperation.

[0099] Specifically, this embodiment provides an implementation of a third connecting part 53 and a fourth connecting part 12. By providing a third connecting part 53 in the dewatering scraper assembly 50 and a fourth connecting part 12 in the housing 10, and by enabling the third connecting part 53 and the fourth connecting part 12 to cooperate through a shaft hole or by sliding, the relative position between the dewatering scraper assembly 50 and the housing 10 can be adjusted, for example, by causing the dewatering scraper assembly 50 to rotate or slide.

[0100] In some embodiments, as shown in Figures 1 to 5, the third connecting part 53 on the wringer assembly 50 is a rotating shaft or a hole-like structure, and the fourth connecting part 12 on the housing 10 is a hole-like structure or a rotating shaft. The third connecting part 53 and the fourth connecting part 12 cooperate through a shaft hole to realize the rotation of the wringer assembly 50. Alternatively, the third connecting part 53 and the fourth connecting part 12 can directly cooperate and rotate through sliding friction, or a bearing can be provided between the third connecting part 53 and the fourth connecting part 12 to rotate through rolling friction.

[0101] In some embodiments, as shown in Figures 10 and 11, the third connecting portion 53 on the wringer assembly 50 is a slider-like structure, and the fourth connecting portion 12 on the housing 10 is a slide rail-like structure or a groove-like structure. The third connecting portion 53 and the fourth connecting portion 12 slide together to adjust the position of the wringer assembly 50. Alternatively, the third connecting portion 53 can be a slide rail-like structure or a groove-like structure, and the fourth connecting portion 12 can be a slider-like structure.

[0104] In some embodiments of this disclosure, the switching member 60 further includes an elastic member 65, which is sleeved on the outside of the guide portion 64, wherein one end of the elastic member 65 abuts against the guide portion 64 and the other end of the elastic member 65 abuts against the support base 14.

[0105] Specifically, this embodiment provides an implementation of the elastic member 65, which is sleeved on the outside of the guide portion 64 and abuts against the support seat 14 inside the housing 10, so that the elastic member 65 can provide a corresponding elastic restoring force during the reciprocating motion of the switching member 60, so that the switching member 60 can be quickly reset during the switching process from the second cleaning mode to the first cleaning mode.

[0106] In some embodiments, the elastic element 65 is a spring sleeved on the outside of the guide portion 64.

[0107] In some embodiments, as shown in FIG6, the guide portion 64 includes a seat body and a shaft body structure, and the elastic member 65 is sleeved on the outside of the shaft body and abuts against the seat body and the support seat 14 respectively.

[0108] In some embodiments of this disclosure, the roller brush 20 includes: a brush body 21; a connecting plate 22 connected to the brush body 21 and extending toward the wheel body 30 when the brush body 21 is installed to the housing 10, the roller brush 20 being detachably connected to the housing 10 via the connecting plate 22; and a pushing part 23 disposed on the connecting plate 22 and located on the side of the connecting brush body 21 near the wheel body 30, extending toward the interior of the housing 10; wherein, when the brush body 21 is installed to the housing 10, the pushing part 23 abuts against the switching member 60; or, there is a gap between the pushing part 23 and the switching member 60.

[0109] Specifically, this embodiment provides an implementation of a roller brush 20, which includes a brush body 21, a connecting plate 22, and a pushing part 23. The brush body 21 is used for cleaning. The connecting plate 22 is connected to the brush body 21 and extends toward the reciprocating motion direction of the switching member 60, providing a setting position for the pushing part 23. The pushing part 23 is correspondingly set with the switching member 60. The corresponding setting here can be abutting or clearance fit.

[0110] In some embodiments, during the process of switching from the first cleaning mode to the second cleaning mode, the pushing part 23 abuts against the switching member 60, thereby driving the reciprocating motion of the switching member 60.

[0111] In some embodiments, the switching member 60 may be provided with a corresponding abutment structure to facilitate cooperation with the pushing part 23. For example, a part protruding from the switching body 63 or a corresponding extension structure may be provided to cooperate with the spatial arrangement of the overall device, so as to realize the cooperation between the pushing part 23 and the switching member 60.

[0112] In some embodiments of this disclosure, the floor brush device includes a plurality of roller brushes 20, the pushing portions 23 of the plurality of roller brushes 20 extending to different lengths toward the interior of the housing 10.

[0113] Specifically, this embodiment provides an implementation of multiple roller brushes 20. By setting the roller brushes 20 in multiple ways, the power to the switching member 60 can be provided according to different usage needs and usage scenarios. In specific applications, the roller brushes 20 can be set as a detachable structure, or they can be set as an integrated structure of multiple brush bodies 21. Users can choose to disassemble them according to their needs or according to the different speed requirements of the first cleaning mode and the second cleaning mode to achieve the corresponding functions. During the switching process between the first cleaning mode and the second cleaning mode, the pushing part 23 needs to abut against the switching member 60 to provide power for the movement of the switching member 60.

[0114] In some embodiments of this disclosure, multiple roller brushes 20 are provided with a single type of brush body 21, and the materials or structures of the single type of brush body 21 of the multiple roller brushes 20 are different; or, multiple roller brushes 20 are provided with multiple types of brush bodies 21, and at least some of the multiple types of brush bodies 21 of the roller brushes 20 are different in material or structure.

[0115] Specifically, this embodiment provides an implementation of the brush body 21. The brush body 21 on the roller brush 20 can be provided in various forms. The roller brush 20 is a detachable structure. When the roller brush 20 shown in FIG8 is installed on the housing 10, as shown in FIG1, the user removes the roller brush 20 shown in FIG8 and installs the roller brush 20 shown in FIG9 onto the housing 10. After installation in the corresponding position, the pushing part 23 of the roller brush 20 in FIG9 drives the switching part 60 to change position, thereby realizing the adjustment of the relative position between the auxiliary wheel assembly 40 and the roller brush 20, as well as the water squeezing scraper assembly 50 and the roller brush 20.

[0116] In one application scenario, as shown in Figures 8 and 9, the roller brush 20 provided in this embodiment has a split structure. That is, the roller brush 20 in Figure 8 is used for the first cleaning mode, and the roller brush 20 in Figure 9 is used for the second cleaning mode. When it is necessary to switch from the first cleaning mode to the second cleaning mode, the user disassembles the roller brush 20 in Figure 8 and installs the roller brush 20 in Figure 9 into the housing 10. After installation in the corresponding position, the pushing part 23 of the roller brush 20 in Figure 9 drives the switching part 60 to change position, thereby realizing the adjustment of the relative position between the auxiliary wheel assembly 40 and the roller brush 20, as well as the water squeezing scraper assembly 50 and the roller brush 20.

[0117] In some embodiments, the roller brush 20 provided in this embodiment has a split structure. The brush body 21 of the roller brush 20 in Figure 8 is a bristle brush, a wool brush, or a rag and a combination thereof, used for cleaning hard floors.

[0118] In some embodiments, the roller brush 20 provided in this embodiment has a split structure. The brush body 21 of the roller brush 20 in Figure 9 is made of bristle brush, rubber brush or a combination thereof, and is used to clean soft floors.

[0119] Furthermore, when the roller brush 20 is set as an integral structure, it is equipped with multiple brush bodies 21. By utilizing the characteristics of the brush bodies 21 at different speeds, the speed of the roller brush 20 is changed. At a lower speed, the bristles are used for wet cleaning. At a higher speed, the bristles are thrown out under centrifugal force to clean soft floors.

[0120] In some embodiments, as shown in FIG9, the roller brush 20 provided in this embodiment is an integral structure, that is, the roller brush 20 in FIG9 is provided with two kinds of brush bodies 21. The materials of the two kinds of brush bodies 21 are respectively short but fluffy bristles and long but flat bristles or rubber brush structure. By changing the rotation speed of the roller brush 20, the bristles are used for wet cleaning at a lower rotation speed, and when the rotation speed of the roller brush 20 is higher, the bristles are thrown out under the action of centrifugal force to clean soft floors.

[0121] In some embodiments of this disclosure, the length of the pushing part 23 extending toward the interior of the housing 10 is adjustable.

[0122] Specifically, this embodiment provides an implementation of the pushing part 23. When the user needs to switch cleaning modes, he / she can choose to disassemble the roller brush 20 and replace it with a roller brush 20 that matches the cleaning mode. Alternatively, the user can adjust the length of the pushing part 23 in the housing 10 to adjust the contact state between the pushing part 23 and the switching member 60, thereby adjusting the reciprocating motion of the switching member 60.

[0123] In some embodiments, as shown in FIG9, the roller brush 20 provided in this embodiment is an integral structure, and the pushing part 23 in FIG9 is a structure with adjustable depth. That is, after the roller brush 20 in FIG9 is installed in the housing 10, when the user needs to switch to the second cleaning mode, there is no need to replace the roller brush 20. Just press the pushing part 23 to achieve the contact between the pushing part 23 and the switching part 60, thereby realizing the switching of the second cleaning mode. By using the different rotation speeds of the first cleaning mode and the second cleaning mode, and with the two types of brush bodies 21, one type of brush body 21 plays the role of cleaning at low speed and the other type of brush body 21 plays the role of cleaning at high speed.

[0124] In some embodiments, the pusher 23 and the connecting plate 22 are detachably connected. After the user removes the roller brush 20 from the housing 10, the user replaces the pusher 23 with a different length connected to the connecting plate 2, and installs the roller brush 20 with the pusher 23 of a different length onto the housing 10 so that the pusher 23 abuts against the switching member 60, thereby adjusting the relative position of the switching member 60.

[0125] In some embodiments of this disclosure, the roller brush 20 is provided with brush bodies 21 of various materials or structures.

[0126] Specifically, this embodiment provides an implementation method for the brush body 21. The setting of brush bodies 21 with various materials or structures can meet the needs of users for different cleaning scenarios.

When it is necessary to switch from the first cleaning mode to the second cleaning mode, the user disassembles the roller brush 20 in Figure 8 and installs the roller brush 20 in Figure 9 into the housing 10. After installation in the corresponding position, the pushing part 23 of the roller brush 20 in Figure 9 drives the switching part 60 to change position, thereby realizing the adjustment of the relative position between the auxiliary wheel assembly 40 and the roller brush 20, as well as the water squeezing scraper assembly 50 and the roller brush 20.

[0128] In some embodiments, the roller brush 20 provided in this embodiment has a split structure. The brush body 21 of the roller brush 20 in Figure 8 is a bristle brush, a wool brush, or a rag and a combination thereof, used for cleaning hard floors.

[0129] In some embodiments, the roller brush 20 provided in this embodiment has a split structure. The brush body 21 of the roller brush 20 in Figure 9 is made of bristle brush, rubber brush or a combination thereof, and is used to clean soft floors.
