Description

TECHNICAL FIELD

[0001] The utility model relates to cleaning technical field, especially a floor brush and cleaning equipment. BACKGROUND

[0002] With the continuous improvement of household cleaning demand, the scrubber, the wash and mop integrated machine and the like as a kind of efficient, convenient intelligent cleaning equipment, are widely concerned by market.For example, the scrubber, the scrubber is cleaned through the brush bottom of the rolling brush, carpet, wall surface and the like waiting for cleaning surface, especially suitable for a variety of scenes such as family, commercial place.

[0003] At present, some scrubbers are obviously improved in cleaning efficiency by installing scraping strip assembly on the front side of the rolling brush, but it also causes the following problems: in the process of pushing the brush forward, although the scraping strip assembly is raised, the ground clearance between the scraping strip assembly and the ground is still small, and it is easy to cause jam when dealing with large particle dirt, so that the equipment is forced to slow down or trigger protection shutdown.Furthermore, the front side of the rolling brush of the current scrubber is thick, which destroys the streamline appearance of the brush and affects the use experience;Moreover, when the brush is pulled backward, the dirt on the cleaning surface is scraped off by the scraping strip assembly, and the water stain left by the scraping strip assembly on the ground is wide. SUMMARY

[0004] In view of the above problems, the present application provides a cleaning equipment, which can increase the ground clearance of the scraping strip assembly at the lifting position of the scraping strip assembly, improve the cleaning ability of large particle dirt, and also can thin the thickness of the front side of the cleaning piece, improve the use experience, and the water mark generated by the scraping strip assembly is narrower when the scraping strip assembly is in the descending position.

[0005] In order to achieve the above purpose, the present application provides the following technical scheme:

[0006] The first aspect of the present application provides a floor brush, which comprises:

[0007] The floor brush body can move on the cleaning surface along the direction of travel;

[0008] The cleaning piece is connected to the floor brush body, and the cleaning piece is used for cleaning the cleaning surface, and the cleaning piece has a center axis and a center section, the center axis is located on the center section, and the center section is perpendicular to the direction of travel;

[0009] The scraping strip assembly is arranged on the front side of the cleaning piece in the direction of travel;

[0010] The driving assembly comprises a driving structure arranged in the brush body and a transmission structure, the transmission structure comprises a connecting rod mechanism, the driving structure is at least partially located at the rear side of the central section in the advancing direction; one end of the transmission structure is connected to the driving structure, and the other end of the transmission structure is limited to the scraping strip assembly and is located above or behind the cleaning member;

[0011] Under the driving action of the driving structure, the other end of the transmission structure drives the scraping strip assembly to move towards the surface to be cleaned, so that the scraping strip assembly can scrape off the dirt on the surface to be cleaned; or the other end of the transmission structure drives the scraping strip assembly to move away from the surface to be cleaned.

[0012] Since the driving structure is at least partially located at the rear side of the central section in the advancing direction, one end of the transmission structure is connected to the driving structure, and the other end of the transmission structure is connected to the scraping strip assembly and is located above or behind the cleaning member, so that the driving structure and the transmission structure are not arranged at the front side at the same time, which reduces the influence of the overall driving assembly on the thickness of the front side of the rolling brush, and is beneficial to reducing the thickness of the front side of the cleaning member. Moreover, since the driving structure and the transmission structure are more rearward, more space is reserved for the lifting of the scraping strip assembly, the scraping strip assembly can be lifted to a higher position, thereby increasing the ground clearance. During cleaning, large particles of dirt are less likely to be blocked by the scraping strip assembly and are more likely to be sucked in, thereby improving the cleaning ability of large particles of dirt during cleaning.

[0013] Generally, for cleaning equipment without a scraping strip assembly, the front side of the rolling brush covers a cover plate, which is used to block dirt from being thrown to the ground under the action of the centrifugal force of the rotating rolling brush. The ground clearance of the scraping strip assembly in the lifted position of the embodiment of the present application is similar to the ground clearance between the cover plate and the ground of such cleaning equipment without a scraping strip assembly, which significantly reduces the problem of large particle jamming.

[0014] Alternatively, the other end of the transmission structure drives the scraping strip assembly to move around the central axis towards the surface to be cleaned; or the other end of the transmission structure drives the scraping strip assembly to move around the central axis away from the surface to be cleaned.

[0015] Since the transmission structure drives the scraping strip assembly to move around the central axis towards the surface to be cleaned, the scraping strip also rotates relative to the ground in this rotating descent, so that the bottom wall of the scraping strip does not come into contact with the ground, but the outer edge of the scraping strip comes into contact with the ground, forming a linear water mark with the ground, rather than the existing substantially rectangular water mark (similar to the shape of the bottom wall), the water mark is narrower, and the user experience is better.

[0016] Optionally, the cleaning member is a rolling brush;

[0017] The other end of the transmission structure is located above the cleaning member, and the angle between the other end of the transmission structure and the roll brush axis relative to the center section is between -10° and 10°.

[0018] The other end of the transmission structure is located behind the cleaning member, and the angle between the other end of the transmission structure and the roll brush axis relative to the center section is between 10° and 90°.

[0019] The transmission structure is located between the scraping strip assembly and the driving structure along a direction substantially parallel to the travel direction, and the layout meeting the above parameters can further ensure the lifting space of the scraping strip assembly, and is beneficial to increasing the ground clearance between the scraping strip assembly and the ground and reducing the thickness in front of the cleaning member.

[0020] Optionally, one end of the connecting rod mechanism is rotationally connected with the driving structure, and the other end of the connecting rod mechanism is used to drive the scraping strip assembly to move towards the surface to be cleaned.

[0021] The connecting rod mechanism can realize complex motion transmission in a limited space, has good reliability, and is beneficial to reducing the occupation of the space above the floor brush and compacting the structure.

[0022] Optionally, the scraping strip assembly is provided with a guide slope, and under the driving action of the driving structure, the end of the transmission structure away from the driving structure abuts against the guide slope and moves along the guide slope to push the scraping strip assembly towards the surface to be cleaned; or,

[0023] The transmission structure is connected with the scraping strip assembly, and under the driving action of the driving structure, the end of the transmission structure away from the driving structure pushes the scraping strip assembly towards the surface to be cleaned.

[0024] When the transmission structure and the scraping strip assembly are limited in position in the abutting mode, the transmission structure abuts against the lower end of the guide slope when the scraping strip assembly is in the lowered position, and the transmission structure abuts against the upper end of the guide slope when the scraping strip assembly is in the lifted position. During switching between the lowered position and the lifted position of the scraping strip assembly, the transmission structure slides between the upper end and the lower end of the guide slope.

[0025] The abutting mode of the transmission structure and the guide slope is simple and convenient, and has low cost. Moreover, the guide slope can be used to change the direction of the force transmitted by the transmission structure, so that the transmission structure and the scraping strip assembly are more flexible in the layout in space, which is beneficial to providing more space for lifting the scraping strip assembly.

[0026] The transmission structure and the scraping strip assembly adopt the abutting mode, and mainly rely on the friction force between them to maintain the relative position, so that the scraping strip assembly can be quickly disassembled under the action of a small external force without the aid of tools.

[0027] When the connection mode is used to limit the position between the transmission structure and the scraping strip assembly, the connection between the transmission structure and the scraping strip assembly is more reliable.

[0028] Optionally, the transmission structure comprises a first arm and a second arm, one end of the first arm is rotatably connected to the driving structure, the other end of the first arm is rotatably connected to one end of the second arm, and the other end of the second arm is a free end and abuts against the guide slope.

[0029] When the driving assembly drives the scraping strip assembly to descend in a rotating manner, but the position of the scraping strip assembly in the transverse direction (parallel to the axial direction of the rolling brush) is not expected to change, and when the scraping strip assembly is in the process of switching between the lifting position and the descending position, the abutting position between the transmission structure and the guide slope changes, and the first arm and the second arm connected by the hinge can flexibly adapt to the change in position, and the structure is simple, and the transverse movement of the scraping strip assembly is avoided.

[0030] Optionally, the floor brush further comprises a support column, the support column is located between the two ends of the second arm, and the second arm is rotatably connected to the support column.

[0031] The support column is used to support the second arm, so as to ensure that the movement of the second arm is stable and reliable, and the descending of the scraping strip assembly is more stable and reliable.

[0032] Optionally, the axis of the output shaft of the driving structure and the axis of the support column are parallel to the central section, one end of the first arm rotates relative to the axis of the output shaft, the other end of the first arm drives the second arm to rotate around the support column, and the first arm and the second arm are substantially parallel to the horizontal plane.

[0033] This layout not only makes full use of the space above the floor brush to place the first arm and the second arm, but also makes full use of the internal space of the floor brush to place the driving structure, and the structure is more reasonable and compact.

[0034] Optionally, the scraping strip assembly comprises a base and a scraping strip, one end of the base is connected with the scraping strip, and the other end of the base is provided with the guide slope.

[0035] The base not only serves as a mounting carrier for the scraping strip, but also is used to connect the transmission assembly to realize power transmission. The guide slope is part of the base, and no additional connection structure is needed to realize force transmission with the transmission structure, and the structure is simple and compact.

[0036] Optionally, the side surface of the base facing the cleaning member is a curved surface structure.

[0037] The base of the curved structure can better match the shell part above the rolling brush and can be driven to rotate and descend along the circumference of the rolling brush under the driving of the transmission structure. The curved structure has a larger contact area with the shell part above the rolling brush, which is conducive to improving the stability and reliability of the lifting process of the scraping strip assembly.

[0038] Optionally, the floor brush further comprises elastic members, which are respectively connected to the floor brush body and the base;

[0039] When the floor brush body moves in the direction opposite to the travel direction, the driving structure drives the scraping strip assembly to move towards the surface to be cleaned through the transmission structure, and the elastic members are deformed during the movement of the scraping strip assembly to store energy in the elastic members;

[0040] When the floor brush body moves in the travel direction, the elastic members release the stored energy to drive the scraping strip assembly to move away from the surface to be cleaned.

[0041] When the scraping strip is needed to scrape the dirt on the ground (for example, when the floor brush is pulled backward), the driving assembly drives the scraping strip assembly to move towards the ground, and the elastic members are elastically deformed by overcoming the elastic restoring force of the elastic members; when the scraping strip is needed to move away from the ground (for example, when the floor brush is pushed forward), the driving assembly can not apply a driving force to the scraping strip assembly, and the elastic members are driven to automatically lift the scraping strip by the elastic restoring force. The use of the elastic members to lift the scraping strip assembly can make the scraping strip assembly have a faster response speed during resetting, and the use of the driving assembly only to drive the scraping strip assembly to descend can also help the device to reduce energy consumption.

[0042] Optionally, the other end of the base is provided with a first mounting portion and a second mounting portion protruding from the first mounting portion towards the driving assembly, and the guide inclined surface is located in the second mounting portion, and the elastic members are connected to the first mounting portion.

[0043] Compared with the second mounting portion, the first mounting portion belongs to a recessed area, and the installation of the elastic members in the first mounting portion can make full use of the recessed area and improve the space utilization and the compactness of the structure.

[0044] The second aspect embodiment of the present application provides a cleaning device, which comprises:

[0045] The floor brush of the first aspect embodiment;

[0046] A machine body, which is rotatably connected to the floor brush.

[0047] The second aspect embodiment comprises the floor brush of the first aspect embodiment, and therefore has the same beneficial effects as described above, which will not be described again. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0058] In order to make the technical scheme and beneficial effects of the utility model more obvious and easy to understand, the following will be described in detail by means of listing specific embodiments. In the drawings, the parts are not necessarily drawn to scale, and local features can be enlarged or reduced to more clearly show the details of the local features; unless otherwise defined, the technical and scientific terms used herein have the same meaning as the technical and scientific terms in the technical field to which the present application belongs.

[0059] In the description of the utility model, the orientation or positional relationship indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "height", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of the simplified description of the utility model, and does not indicate that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, that is, it cannot be understood as a limitation on the utility model.

[0060] In the utility model, the terms "first" and "second" are only used for the purpose of clear description, and cannot be understood as the relative importance of the indicated features or the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly include at least one of the features. In the description of the utility model, the meaning of "multiple" is at least two, for example, two, three, etc.

[0061] The cleaning equipment of the embodiments of the present application includes but is not limited to a scrubber, a washing and mopping integrated machine, an electric mop and the like. The aforementioned cleaning member includes but is not limited to a single roller brush, a double roller brush, a track and the like. The surface to be cleaned includes but is not limited to a ground, a carpet, a floor, a wall surface and the like.

[0062] The cleaning equipment includes a floor brush 100 and a cleaning member installed at the bottom of the floor brush 100. During the movement of the floor brush 100 on the surface to be cleaned, the cleaning member can clean and brush the surface to be cleaned, so as to achieve the cleaning purpose. The scraping strip assembly 130 is located in front of the cleaning member. When the floor brush 100 moves forward, the scraping strip assembly 130 is in a lifting position (see Figure 2 A position in FIG. 5), so that there is a large ground clearance between the scraping strip assembly 130 and the surface to be cleaned, facilitating the suction of dirt. When the floor brush 100 moves backward, the scraping strip assembly 130 is in a descending position (see Figure 2 B position in FIG. 6), so that the scraping strip assembly 130 is in contact with the surface to be cleaned, and the dirt on the surface to be cleaned is scraped off, improving the cleaning efficiency and cleaning effect.

[0063] Exemplarily, the cleaning device can also be provided with a sensor and a driver. The sensor can be used to sense the forward or backward movement of the floor brush 100. When the floor brush 100 moves forward, the controller controls the driving assembly 140 to drive the scraping strip assembly 130 to lift up and separate from the ground. When the floor brush 100 moves backward or stops moving due to the collision with the front obstacle, the controller controls the driving assembly 140 to drive the scraping strip assembly 130 to lower down and make an interference contact with the ground, so as to remove the water stains left on the ground when the floor brush 100 is pulled backward.

[0064] As shown in Figure 4 , the lifting movement of the scraping strip assembly 130 is realized by the driving assembly 140. The addition of the scraping strip assembly 130 means not only the addition of the scraping strip assembly 130 itself, but also the additional addition of the driving assembly 140.

[0065] In the existing cleaning device, the existing driving assembly occupies a large space on the front side of the cleaning piece, and even partially stacks with the existing scraping strip assembly. This not only leads to the thickening of the size of the front side of the cleaning piece, but also leads to the limitation of the lifting space of the existing scraping strip assembly due to the insufficient space between the existing driving assembly and the front side of the cleaning piece and the surface to be cleaned. The ground clearance between the existing scraping strip assembly and the surface to be cleaned cannot meet the demand.

[0066] Moreover, the existing scraping strip assembly adopts an up-down movement mode to realize lifting. In this way, the whole existing scraping strip assembly is located in front, and the distance between the existing scraping strip assembly and the surface to be cleaned is small. In order to drive the existing scraping strip assembly, the existing driving assembly also needs to be extended to the front side or even downward. These not only make it difficult to improve the ground clearance, but also lead to the increase in the thickness of the front side of the cleaning piece.

[0067] Furthermore, as shown in Figure 1 , the scraping strip of the scraping strip assembly 130 itself has a certain thickness. Due to the down movement mode (which can be understood as: straight up and down along the vertical direction perpendicular to the horizontal plane) adopted in the prior art, the entire bottom wall (see the bottom wall 1321 of the scraping strip assembly 130 in Figure 1 ) of the existing scraping strip assembly will be in contact with the surface to be cleaned. The residual water mark is wide, and the water mark is a rectangle with the same or similar shape as the bottom wall 1321, and the width is comparable to the width of the bottom wall 1321. The use experience is affected.

[0068] In order to improve the above problems, the embodiments of the present application provide the following technical solutions. The cleaning device of the embodiments of the present application will be described in detail below. Figures 1 to 7

[0069] Embodiment 1

[0070] See Figure 2 and Figure 4 ​As shown, the floor brush 100 of the embodiment 1 comprises a floor brush body 110, a cleaning piece, a squeegee assembly 130 and a driving assembly 140. Figure 4 The floor brush body 110 is capable of moving on a surface to be cleaned in a moving direction; the cleaning piece is connected to the floor brush body 110, and is used to clean the surface to be cleaned; and the driving assembly 140 is used to drive the squeegee assembly 130 to move, so as to realize the lifting or lowering of the squeegee assembly 130 relative to the surface to be cleaned.

[0071] For the convenience of description, it is assumed that Figure 2 The moving direction is a forward direction substantially parallel to the surface to be cleaned, and the surface to be cleaned is taken as a ground, and the cleaning piece is taken as a single cylindrical roller brush.

[0072] As shown in the figures, Figure 5 The cleaning piece has a central axis and a central section O1, the central axis is located on the central section, and the central section is perpendicular to the moving direction; the squeegee assembly 130 is arranged on the front side of the cleaning piece in the moving direction; the driving assembly 140 comprises a driving structure 141 arranged in the floor brush body 110 and a transmission structure 142, the driving structure 141 is at least partially located on the rear side of the central section in the moving direction; one end of the transmission structure 142 is connected to the driving structure 141, and the other end of the transmission structure 142 is limited to the squeegee assembly 130 and is located above or behind the cleaning piece; under the driving action of the driving structure 141, the other end of the transmission structure 142 drives the squeegee assembly 130 to move towards the surface to be cleaned, so that the squeegee assembly 130 can scrape off the dirt on the surface to be cleaned.

[0073] The driving structure 141 is used to provide driving force, for example, the driving structure 141 can be a motor, a rudder, etc.

[0074] In other implementations, the other end of the transmission structure 142 can also drive the squeegee assembly 130 to move away from the surface to be cleaned, so as to facilitate dirt suction. For example, when the squeegee 132 needs to scrape off the dirt on the ground (such as when the floor brush 100 is pulled backward), the motor is forward rotated, the transmission structure 142 drives the squeegee assembly 130 to move towards the ground, and the squeegee assembly 130 can abut against the ground to scrape off the dirt; when the squeegee 132 needs to move away from the ground (such as when the floor brush 100 is pushed forward), the motor is reversed, the transmission structure 142 drives the other end of the transmission structure 142 to reversely drive the squeegee assembly 130 to move away from the ground around the central axis, so as to move the squeegee assembly 130 away from the ground, increase the ground clearance, and facilitate dirt suction.

[0075] For example, the other end of the transmission structure 142 drives the scraper assembly 130 to move around the central axis of the cleaning component toward the surface to be cleaned; or, the other end of the transmission structure 142 drives the scraper assembly 130 to move around the central axis of the cleaning component away from the surface to be cleaned.

[0076] The transmission structure 142 is used to transmit the driving force generated by the drive structure 141 to the scraper assembly 130, driving the scraper assembly 130 to move, thereby switching the scraper assembly 130 between a raised position and a lowered position. In this embodiment, the raised position refers to the highest position where the drive assembly 140 can raise the scraper assembly 130, at which point the ground clearance between the scraper assembly 130 and the ground is at its maximum. The lowered position refers to the lowest position where the drive assembly 140 can lower the scraper assembly 130, at which point the scraper assembly 130 is in interference contact with the ground.

[0077] In this embodiment, since the drive structure 141 is at least partially located on the rear side of the central section in the direction of travel, one end of the transmission structure 142 is connected to the drive structure 141, and the other end of the transmission structure 142 is connected to the scraper assembly 130, and is located above or behind the cleaning component. Therefore, neither the drive structure 141 nor the transmission structure 142 is simultaneously positioned on the front side with the cleaning component, reducing the overall impact of the drive assembly 140 on the thickness of the front side of the roller brush 120, which is beneficial for reducing the thickness of the front side of the cleaning component. Furthermore, since the drive structure 141 and the transmission structure 142 are positioned further back, more space is reserved for the lifting of the scraper assembly 130, allowing it to be raised to a higher position, thereby increasing the ground clearance. During cleaning, large particles of dirt are less likely to be blocked by the scraper assembly 130 and are more easily sucked in, improving the cleaning ability for large particles of dirt during the cleaning process.

[0078] Generally, for cleaning equipment without the scraper assembly 130, a cover plate is placed over the front of the roller brush 120 to prevent dirt from being thrown to the ground by the centrifugal force of the rotating roller brush 120. In this embodiment, the ground clearance of the scraper assembly 130 in the raised position is similar to the ground clearance between the cover plate and the ground of such a cleaning equipment without the scraper assembly, significantly reducing the problem of large particles getting stuck.

[0079] For example, Figure 4 In the embodiment shown, the drive structure 141 is entirely located behind the center section, see [reference]. Figure 5 The transmission structure 142 is also almost entirely located behind the center section.

[0080] See Figure 4 As shown, the scraper assembly 130 includes a base 131 and a scraper 132. The base 131 is connected to the transmission structure 142 and the scraper 132 respectively. When the scraper assembly 130 is in the descending position, it relies on the scraper 132 to make interference contact with the ground.

[0081] As the transmission structure 142 drives the wiper strip assembly 130 to move around the central axis towards the surface to be cleaned, referring to Figure 3 , when the rotation and descent mode is adopted, the wiper strip 132 will also rotate relative to the ground, and thus the bottom wall 1321 Figure 1 of the wiper strip 132 will not be in full contact with the ground, but the outer edge 1322 of the wiper strip 132 will be in contact with the ground, and the outer edge 1322 will form a linear water mark with the ground, instead of Figure 1 a generally rectangular water mark, and the water mark will be narrower, and the user experience will be better.

[0082] According to some optional embodiments, referring to Figure 5 , the cleaning member is the roller brush 120; the other end of the transmission structure 142 (in Figure 5 , the other end of the transmission structure 142 is the other end of the second arm 1422, which will be mentioned below) located above the cleaning member includes: the included angle a1 of the other end of the transmission structure 142 with the central section of the line connecting the axis of the roller brush 120 is between -10° and 10°; the other end of the transmission structure 142 located behind the cleaning member includes: the included angle a2 of the other end of the transmission structure 142 with the central section of the line connecting the axis of the roller brush 120 is between 10° and 90°.

[0083] The included angle a1 of the other end of the transmission structure 142 with the central section of the line connecting the axis of the roller brush 120 is more preferably between -5° and 5°.

[0084] Referring to Figure 4 , along a direction generally parallel to the advancing direction, the transmission structure 142 is located between the wiper strip assembly 130 and the driving structure 141, and the layout meeting the above parameters can further ensure the lifting space of the wiper strip assembly 130, which is conducive to increasing the ground clearance between the wiper strip assembly 130 and the ground and reducing the thickness in front of the cleaning member.

[0085] In some implementations, referring to Figure 5 , the other end of the transmission structure 142 is the most front part of the transmission structure 142. In Figure 5 the implementation shown, the included angle a11 of the other end of the transmission structure 142 with the central section of the line connecting the axis of the roller brush 120 is generally -3°.

[0086] Referring to Figure 5 , when the wiper strip assembly 130 is in the lifted position, the position of the wiper strip 132 is generally located on a horizontal plane O2 passing through the center of the roller brush 120, or the position of the wiper strip 132 is located within 5 mm below the horizontal plane.

[0087] According to some optional embodiments, referring to Figure 4 and Figure 6As shown, the transmission structure 142 comprises a linkage mechanism.

[0088] Optionally, one end of the linkage mechanism is rotationally connected with the driving structure 141, and the other end of the linkage mechanism is configured to drive the scraping strip assembly 130 to move towards the surface to be cleaned.

[0089] The linkage mechanism can realize complex motion transmission in a limited space, has good reliability, and is conducive to reducing the occupation of the space above the floor brush 100 and compacting the structure.

[0090] The linkage mechanism can be a hinged combination of multiple rigid rods, such as Figure 4 and Figure 6 As shown, the linkage mechanism comprises two links, and the two links are connected in series. Alternatively, the linkage mechanism can also be a three-link or four-link mechanism, and the number of links is not limited.

[0091] The linkage mechanism can comprise one link, and the two ends of the link can be respectively connected with the scraping strip assembly 130 and the driving structure 141.

[0092] In some implementations, the transmission mechanism can also be a cam structure, but is not limited thereto.

[0093] According to some optional embodiments, as shown in Figure 4 , Figure 6 and Figure 7 , the scraping strip assembly 130 is provided with a guide slope 1311, and the transmission structure 142 abuts against the guide slope 1311; under the driving action of the driving structure 141, the transmission structure 142 moves along the guide slope 1311 to push the scraping strip assembly 130 towards the surface to be cleaned.

[0094] The transmission structure 142 can always abut against the guide slope 1311, and when the transmission structure 142 moves in a preset direction along the guide slope 1311, the transmission structure 142 drives the scraping strip assembly 130 to descend. As shown in Figure 7 , when the scraping strip assembly 130 is in a descending position, the transmission structure 142 contacts the rear end of the guide slope 1311; as shown in Figure 4 and Figure 6 , when the scraping strip assembly 130 is in a lifting position, the transmission structure 142 contacts the front end of the guide slope 1311. During the switching of the scraping strip assembly 130 between the descending position and the lifting position, the transmission structure 142 slides between the upper end and the lower end of the guide slope 1311.

[0095] The transmission structure 142 and the guide slope 1311 abut in this way, which is simple, convenient and low in cost. Moreover, the guide slope 1311 can change the direction of the force transmitted by the transmission structure 142, so that the transmission structure 142 and the wiper strip assembly 130 can be arranged more flexibly in space, which is conducive to providing more space for lifting the wiper strip assembly 130.

[0096] In the embodiments shown in the drawings, the guide slope 1311 is arranged at an angle to the axis of the rolling brush 120 and is inclined from front to back. When the transmission structure 142 slides along the guide slope 1311 from back to front, the transmission structure 142 pushes the wiper strip assembly 130 to lift.

[0097] In some implementations, the guide slope 1311 can be located in a groove, and the other end of the transmission structure 142 can be partially inserted into the groove to abut against the guide slope 1311. Alternatively, the guide slope 1311 can be a convex surface on the wiper strip assembly 130, and the other end of the transmission structure 142 can be provided with a groove, and the convex surface can be partially inserted into the groove to abut against the guide slope 1311.

[0098] During cleaning, the wiper strip assembly 130 directly contacts dirt, and after completing the cleaning work, it may need to be disassembled for cleaning. Moreover, the wiper strip 132 of the wiper strip assembly 130 is prone to loosening or damage after long-term friction with the ground, and needs to be disassembled for replacement. The transmission structure 142 and the wiper strip assembly 130 are connected in an abutting manner, which can more conveniently and quickly disassemble the wiper strip assembly 130. Specifically, the transmission structure 142 abuts against the guide slope 1311, and the relative positions of the two are mainly maintained by friction. The wiper strip assembly 130 can be quickly disassembled under the action of a small external force without the need for tools.

[0099] In other implementations, the end of the transmission structure 142 away from the driving structure 141 can not be limited to the wiper strip assembly 130 in an abutting manner. For example, the transmission structure 142 is connected to the wiper strip assembly 130, and under the driving action of the driving structure 141, the end of the transmission structure 142 away from the driving structure pushes the wiper strip assembly 130 towards the surface to be cleaned. The connection between the transmission structure 142 and the wiper strip assembly 130 can be detachable or fixed, such as buckle connection, screw connection, thread connection, bonding, welding, etc.

[0100] According to some optional embodiments, as shown in Figure 6 The transmission structure 142 includes a first arm 1421 and a second arm 1422. One end of the first arm 1421 is rotatably connected to the driving structure 141, the other end of the first arm 1421 is rotatably connected to one end of the second arm 1422, and the other end of the second arm 1422 is a free end and abuts against the guide slope 1311.

[0101] The driving assembly 140 drives the wiper strip assembly 130 to rotate downward, but the wiper strip assembly 130 is not expected to have a transverse (i.e., parallel to the axial direction of the rolling brush 120) position change, and thus the wiper strip assembly 130 is in the process of switching between the raised position and the lowered position, the abutting position of the transmission structure 142 and the guide slope 1311 is different, and the first arm 1421 and the second arm 1422 connected by the hinge can flexibly adapt to the position change, and the structure is simple, avoiding transverse movement of the wiper strip assembly 130.

[0102] According to some optional embodiments, referring to Figure 4 , the floor brush 100 further comprises a support column 160, the support column 160 is located between the two ends of the second arm 1422, and the second arm 1422 is rotatably connected to the support column 160. The support column 160 is used to support the second arm 1422, so as to ensure that the second arm 1422 moves stably and reliably, and thus the wiper strip assembly 130 is lowered more stably and reliably.

[0103] Non-limitingly, in Figure 4 the embodiment shown, the support column 160 is located at a position substantially in the middle of the second arm 1422.

[0104] According to some optional embodiments, as shown in Figure 4 , the axis of the output shaft of the driving structure 141 and the axis of the support column 160 are both parallel to the central section, one end of the first arm 1421 rotates relative to the axis of the output shaft, the other end of the first arm 1421 drives the second arm 1422 to rotate around the support column 160, and the first arm 1421 and the second arm 1422 are substantially parallel to the horizontal plane. The horizontal plane is substantially perpendicular to the central section. This layout not only makes full use of the space above the floor brush 100 to place the first arm 1421 and the second arm 1422, but also makes full use of the internal space of the floor brush 100 to place the driving structure 141, and the structure is more reasonable and compact.

[0105] In Figure 4 the implementation shown, the first arm 1421 and the second arm 1422 are both located above the driving structure 141.

[0106] According to some optional embodiments, as shown in Figure 4 and Figure 6 , the wiper strip assembly 130 comprises a base 131 and a wiper strip 132, one end of the base 131 is connected with the wiper strip 132, and the other end of the base 131 is provided with a guide slope 1311. The base 131 serves as a mounting carrier for the wiper strip 132 and is also used to connect the transmission assembly to realize power transmission. The guide slope 1311 is part of the base 131, and no additional connecting structure is needed to realize force transmission with the transmission structure 142, and the structure is simple and compact.

[0107] According to some optional embodiments, asFigure 6 and Figure 7 As shown in FIG. 1, the base 131 has a curved surface structure.

[0108] The curved surface structure of the base 131 can better match the shell portion 111 above the roller brush 120 (see FIG. 1), and can be lowered along the circumference of the roller brush 120 under the drive structure 142. The curved surface structure has a larger contact area with the shell portion 111 above the roller brush 120, which is conducive to improving the stability and reliability of the lifting process of the scraping strip assembly 130. Figure 4

[0109] During switching between the lifting position and the lowering position, the base 131 rotates along the outer periphery of the roller brush 120. The base 131 is located on the front side of the cleaning member, and the scraping strip 132 is located below the base 131. The base 131 can be made of a hard material, and the scraping strip 132 can be at least partially made of a soft material to avoid scratching the ground by the scraping strip 132.

[0110] According to some optional embodiments, as shown in FIG. 1 and FIG. 2, the floor brush 100 further comprises an elastic member 150 connected to the floor brush body 110 and the base 131, respectively. When the floor brush body 110 moves in the direction opposite to the travel direction, the drive structure 141 drives the scraping strip assembly 130 to move towards the surface to be cleaned through the transmission structure 142. The scraping strip assembly 130 drives the elastic member 150 to deform during the movement, so that the elastic member 150 stores energy. When the floor brush body 110 moves in the travel direction, the elastic member 150 releases energy to drive the scraping strip assembly 130 to move away from the surface to be cleaned. Figure 4 Figure 6 When it is necessary to scrape the dirt on the ground by the scraping strip 132 (for example, when the floor brush 100 is pulled backward), the drive assembly 140 drives the scraping strip assembly 130 to move towards the ground, and at the same time overcomes the elastic restoring force of the elastic member 150 to make the elastic member 150 elastically deform. When it is necessary to move the scraping strip 132 away from the ground (for example, when the floor brush 100 is pushed forward), the drive assembly 140 can not apply a driving force to the scraping strip assembly 130, and the elastic restoring force provided by the elastic member 150 is used to drive the scraping strip 132 to automatically lift. The use of the elastic member 150 to lift the scraping strip assembly 130 can make the scraping strip assembly 130 have a faster response speed during resetting, and the use of the drive assembly 140 only to drive the scraping strip assembly 130 to lower can also be conducive to reducing the energy consumption of the device.

[0111] Non-limitingly, the elastic member 150 includes elastic elements such as springs, elastic rubber, elastic ropes, etc.

[0112] Non-limitingly, the elastic member 150 includes elastic elements such as springs, elastic rubber, elastic ropes, etc.

[0113] ​​It can be understood that, based on the foregoing description, it is more flexible to rely on the driving assembly 140 to drive the squeegee assembly 130 to reset relative to the elastic member 150 driving the squeegee assembly 130 to reset away from the ground.

[0114] Based on the foregoing description, when the reset of the squeegee assembly 130 relies on the driving assembly 140, the elastic member 150 can not be provided. Alternatively, the elastic member 150 can be provided at the same time as the driving assembly 140 drives the squeegee assembly 130 away from the ground, at which time the elastic member 150 can assist the squeegee assembly 130 to reset, or serve as a backup way to drive the squeegee assembly 130 away from the ground in the event of damage to the driving assembly 140, accidental shutdown, and the like. Figure 4 and Figure 6 In the implementation mode shown, the elastic member 150 is a tension spring, and the tension spring is not assembled in place in the figure, only the approximate position is shown. The two ends of the tension spring are hung in the holes of the base 131 and the housing portion 111, respectively, facilitating disassembly, installation, or replacement.

[0115] The embodiment drives the squeegee 132 to move away from the surface to be cleaned by the elastic reset member (i.e., the elastic member 150), so that the squeegee 132 has a faster response speed, i.e., it is beneficial to improve the response speed of the squeegee 132 action.

[0116] Figure 6 Exemplarily, it is shown that the base 131 is provided with the elastic member 150 on both opposite sides, and such a layout can more smoothly drive the squeegee assembly 130 to move.

[0117] In some optional implementation modes, the number of elastic members 150 can also be one, three, or more.

[0118] According to some optional embodiments, as shown in Figure 6 The other end of the base 131 is provided with a first mounting portion 1312 and a second mounting portion 1313 protruding from the first mounting portion 1312 toward the driving assembly 140, the guide inclined surface 1311 is located at the second mounting portion 1313, and the elastic member 150 is connected to the first mounting portion 1312. Relative to the second mounting portion 1313, the first mounting portion 1312 belongs to a recessed area, and mounting the elastic member 150 in the first mounting portion 1312 can make full use of the recessed area, improve the space utilization rate, and have a more compact structure.
