Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning, in particular to a floor brush assembly, a cleaning device and a cleaning system. BACKGROUND

[0002] The cleaning device, for example, a scrubber, is a cleaning machine suitable for cleaning a floor, a carpet or the like, simultaneously absorbing and removing the sewage from the site, and has the advantages of environmental protection, energy saving and high efficiency. The roll brush, as a key component of the cleaning device, is mainly used for cleaning the surface to be cleaned. The rear of the roll brush is provided with a scraping strip. The scraping strip can be used to scrape the water stains left on the surface to be cleaned by the roll brush when the cleaning device is pushed forward, so as to reduce water marks and improve cleaning efficiency.

[0003] However, when the cleaning device is pulled backward, the roll brush will also leave water stains on the surface to be cleaned. In the related art, by using a roll brush material that can dissolve water better, or by adjusting the water output of the water pump to reduce the generation of water stains, the problem of residual water stains when the cleaning device is pulled backward cannot be well solved. Especially, when the roll brush is worn out after long-term use, the water stains generated when the cleaning device is pulled backward increase significantly, thereby increasing the drying time of the surface to be cleaned and reducing the user's experience. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a floor brush assembly, a cleaning device and a cleaning system, which can solve the problem of water stains generated when the cleaning device is pulled backward, thereby reducing the cleaning efficiency and cleaning effect.

[0005] In a first aspect, the present application provides a floor brush assembly, comprising:

[0006] a floor brush main body;

[0007] a roll brush, the roll brush being arranged on the floor brush main body, and the roll brush rotating for cleaning a surface to be cleaned;

[0008] a front scraping strip assembly, the front scraping strip assembly comprising:

[0009] a roll brush cover plate, the roll brush cover plate covering at least part of the roll brush, and the roll brush cover plate having a first position and a second position;

[0010] a front scraping strip, the front scraping strip being arranged on the roll brush cover plate, and along a pushing direction of the floor brush assembly, the front scraping strip being located on a front side of the roll brush, when the floor brush assembly is pushed forward, the roll brush cover plate is in the first position, and the front scraping strip has a spacing with the surface to be cleaned; when the floor brush assembly is pulled backward, the roll brush cover plate is in the second position, and the front scraping strip is in contact with the surface to be cleaned;

[0011] An upper cover body is arranged on the floor brush body. The rolling brush cover plate has an extension part. The upper cover body has a receiving space for accommodating the extension part. When the rolling brush cover plate switches between the first position and the second position, the extension part can be flipped in the receiving space.

[0012] A driving assembly is arranged on the floor brush body. The driving assembly is used to drive the rolling brush cover plate to flip forward or backward, so that the rolling brush cover plate has the first position and the second position. The driving assembly includes an elastic member. The elastic member is used to make the rolling brush cover plate have a flipping movement trend.

[0013] The floor brush assembly provided in the present application can make the rolling brush cover plate have a flipping movement relative to the floor brush body, so as to have the first position and the second position. When the floor brush assembly is pushed forward, the suction port of the floor brush assembly can suck the dirt in front. The rolling brush cover plate can be in the first position, so that the front scraping strip is lifted to have a spacing with the surface to be cleaned. At this time, the front scraping strip cannot push the dirt on the surface to be cleaned away from the suction port. In addition, the front scraping strip cannot block the suction effect of the floor brush assembly on the dirt in front. The larger dirt particles on the surface to be cleaned can enter the suction port through the spacing between the front scraping strip and the surface to be cleaned.

[0014] When the floor brush assembly is pulled backward, the rolling brush cover plate can be in the second position, so that the front scraping strip is lowered to be in contact with the surface to be cleaned. With the backward pulling movement of the floor brush assembly, the front scraping strip can scrape off the water stains on the surface to be cleaned after being cleaned by the rolling brush, and the front scraping strip can drive the dirt between the front scraping strip and the rolling brush backward, so as to be sucked by the suction port.

[0015] When the floor brush assembly is pushed forward to touch an obstacle such as a wall, the rolling brush cover plate is in contact with the wall to have an interaction force. The rolling brush cover plate can be flipped in the direction of the first position under the action of the wall, so that the front scraping strip is lowered to be in contact with the surface to be cleaned. The front scraping strip can be attached to the wall, and the front scraping strip and the wall can have no gap. With the backward pulling movement of the floor brush assembly, the front scraping strip can drive the dirt at the bottom edge of the wall backward, and the dirt can be cleaned by the suction port, so that the sanitary dead angle at the edge position of the wall can be reduced, the cleaning area can be increased, and the cleaning effect can be improved.

[0016] Since the rolling brush cover plate can be flipped relative to the floor brush body, the extension part of the rolling brush cover plate can be flipped upward or downward relative to the floor brush body. The receiving space of the upper cover body can provide a movable space for the upward or downward flipping of the extension part, so that the upward or downward flipping of the extension part is not easily limited, and thus the rolling brush cover plate can be switched between the first position and the second position.

[0017] The driving assembly can be used to provide driving force for the overturning of the rolling brush cover plate. The elastic member can make the rolling brush cover plate have a motion trend of overturning, so that the rolling brush cover plate can be switched between the first position and the second position. Since the elastic member has elasticity, the accumulation or release of elastic force by the elastic member can be used to provide driving force for the overturning of the rolling brush cover plate. Moreover, since the elastic member has elasticity, the elastic member can have a buffering effect, so that the rolling brush cover plate can move stably during overturning, which is beneficial to improving the service life and motion reliability of the rolling brush cover plate.

[0018] According to an embodiment of the present application, the extension and the front scraping strip are respectively located at two ends of the rolling brush cover plate.

[0019] When the extension is overturned downward, the front scraping strip is overturned upward, and the rolling brush cover plate moves in the direction of the first position.

[0020] When the extension is overturned upward, the front scraping strip is overturned downward, and the rolling brush cover plate moves in the direction of the second position.

[0021] In the embodiments of the present application, the rolling brush cover plate can be overturned relative to the floor brush body. By arranging the extension and the front scraping strip at two ends of the rolling brush cover plate, the overall overturning of the rolling brush cover plate can be realized by driving the extension to overturn upward or downward, so as to realize the overturning of the front scraping strip upward or downward.

[0022] It is easy to understand that, since the extension is located at the end of the rolling brush cover plate, the driving assembly can exert a force on the end of the extension away from the front scraping strip, so as to realize a large motion amplitude of the rolling brush cover plate by a small driving force.

[0023] According to an embodiment of the present application, the elastic member abuts against the extension, and the elastic member exerts a force on the extension towards the to-be-cleaned surface, so that the extension is overturned downward, and the rolling brush cover plate has a motion trend of overturning towards the first position.

[0024] The elastic member can be used to drive the rolling brush cover plate to overturn in the direction of the first position. The elastic member can drive the extension to overturn downward by elastic force, so that the front scraping strip can overturn upward, and thus the front scraping strip can be lifted to have a spacing from the to-be-cleaned surface.

[0025] Specifically, when the floor brush assembly is pushed forward, the elastic member can keep the state of pushing the extension to overturn downward, so that the front scraping strip always has a spacing from the to-be-cleaned surface, and thus dirt on the front side of the rolling brush can be sucked into the dirt suction port. When the floor brush assembly is pulled backward, the upward overturning of the extension can make the elastic member elastically deform, and the front scraping strip is lowered to be in contact with the to-be-cleaned surface. At this time, the elastic member can accumulate elastic force, so that the extension can always have a motion trend of overturning downward.

[0026] According to an embodiment of the present application, the elastic member is located in the accommodating space, one end of the elastic member abuts against the upper cover body, and the other end of the elastic member abuts against the extension.

[0027] In the embodiment of the present application, the elastic member can be located in the space between the extension and the upper cover body. The upper end of the elastic member can abut against the surface of the upper cover body facing the extension. The lower end of the elastic member can abut against the upper surface of the extension. When the roller brush cover plate is in the second position, the elastic member is compressed and deformed under the relative action of the extension and the upper cover body. The extension and the elastic member have interaction force, so that the elastic member can accumulate elastic force, thereby providing a motion trend for the downward overturning of the extension.

[0028] According to an embodiment of the present application, the driving assembly further comprises a swing member, the swing member overturns relative to the ground brush body;

[0029] The swing member is used to push the extension to overturn upward when the swing member overturns upward and abuts against the extension;

[0030] And the swing member is used to release the action force of the elastic member when the swing member overturns downward, and the extension overturns downward.

[0031] In the embodiment of the present application, the swing member can be used to drive the extension to move. When the ground brush assembly is pulled backward, the swing member can overturn upward. By abutting against the extension, the swing member can drive the extension to overturn upward synchronously in the process of overturning upward of the swing member, so that the front scraping strip can descend to contact the surface to be cleaned, thereby cleaning the surface to be cleaned.

[0032] In the process of overturning upward of the swing member to overturn upward of the extension, the elastic member can be compressed and deformed. When the swing member overturns upward to the extent that the roller brush cover plate is in the second position, the elastic force accumulated by the elastic member can make the extension have a motion trend of overturning downward. At this time, the action force of the swing member driving the extension to overturn upward is greater than the elastic force of the elastic member, so that the roller brush cover plate can be kept in the second position. When the swing member overturns downward, the abutting force of the swing member against the extension upward can gradually decrease. When the action force generated by the elastic member releasing the elastic potential energy is greater than the abutting force of the swing member against the extension upward, the elastic member can drive the extension to overturn downward, so that the roller brush cover plate can move to the first position.

[0033] It should be noted that the swing member and the extension have a state of mutual abutment, and also can have a state of separation. In other words, the driving force of the extension overturning upward is not limited to the upward overturning of the swing member.

[0034] The driving force for the extension to flip up can be from an obstacle such as a wall. When the mop head assembly is pushed forward to touch the obstacle such as a wall, the wall contacts the roller cover plate and exerts a force on the roller cover plate. The roller cover plate can be flipped to make the front squeegee strip lower to contact the surface to be cleaned, and the extension can be flipped up to overcome the elastic force of the elastic member. At this time, the extension can be separated from the swing member. The roller cover plate moves in the direction of the second position.

[0035] By setting the extension to be separable from the swing member, the entire front squeegee strip assembly can be disassembled to facilitate cleaning of the comb teeth squeegee strip and the dirt suction port on the mop head assembly.

[0036] When the mop head assembly is pushed forward to be in close contact with the wall and cannot be pushed forward any more, the roller cover plate can be in the second position. At this time, the mop head assembly can only be pulled backward. Since the front squeegee strip can be in close contact with the wall, the front squeegee strip can clean the dirt on the edge of the corner of the wall during the backward movement of the mop head assembly. It should be noted that after the roller cover plate is in the second position, the swing member can be controlled to flip up to abut against the extension, so that when the force of the wall on the roller cover plate gradually decreases to zero during the backward movement of the mop head assembly, the swing member can keep the roller cover plate in the second position, thereby reducing the movement of the roller cover plate from the second position to the first position, the front squeegee strip flips up to throw the dirt in the direction of the wall, and the possibility of causing secondary pollution is reduced.

[0037] According to an embodiment of the present application, the length of the force arm of the extension relative to the rotation axis of the roller cover plate is less than the length of the force arm of the front squeegee strip relative to the rotation axis of the roller cover plate.

[0038] In the embodiment of the present application, the roller cover plate can be flipped by the pushing or releasing of the extension by the swing member. Therefore, the force application end of the flipping movement of the roller cover plate is located at the extension. By setting the length of the force arm of the extension relative to the rotation axis to be less than the length of the force arm of the front squeegee strip relative to the rotation axis, the length of the force arm of the force application end can be small, so that a large flipping amplitude of one end of the front squeegee strip can be achieved by a small movement amplitude of the force application end. In the case of a certain movement amplitude of the front squeegee strip, the accommodation space of the upper cover body is saved, and the volume of the mop head assembly is reduced.

[0039] In a second aspect, the present application provides a mop head assembly, comprising:

[0040] a mop body;

[0041] a roller brush arranged on the mop body and rotating for cleaning a surface to be cleaned;

[0042] A front wiper assembly is detachably connected to the floor brush body, and the front wiper assembly comprises a rolling brush cover plate, a front wiper and an upper cover body. The rolling brush cover plate covers at least part of the rolling brush. The front wiper is arranged on the rolling brush cover plate and is located at the front side of the rolling brush in the forward pushing direction of the floor brush assembly. The upper cover body is arranged on the floor brush body.

[0043] A driving assembly is arranged on the floor brush body and is used to drive the rolling brush cover plate to flip up and down to have a first position and a second position. The driving assembly comprises a motor, a swing member and an elastic member. The motor is connected with the swing member. The rolling brush cover plate has an extension part away from the front wiper. The elastic member is connected with the extension part to apply a force to the extension part. The bottom of the extension part is in abutment with the swing member.

[0044] When the floor brush assembly is pushed forward, the rolling brush cover plate is in the first position and the front wiper is in a raised position. When the floor brush assembly is pulled backward, the rolling brush cover plate is in the second position and the front wiper is in a lowered position, and the front wiper is in contact with the surface to be cleaned.

[0045] In the embodiments of the present application, the swing member is in abutment with the extension part. On the one hand, the rolling brush cover plate can be driven to flip relative to the floor brush body and switch between the first position and the second position through the cooperation between the swing member and the extension part. On the other hand, the detachable connection between the front wiper assembly and the floor brush body can be realized. Specifically, the detachable front wiper assembly can facilitate the cleaning of the inner wall of the rolling brush towards the front wiper and the inner wall of the rolling brush towards the rolling brush cover plate. Moreover, after the front wiper assembly is detached, the visible area of the rolling brush can be increased to facilitate the user to detach the rolling brush. In addition, after the rolling brush is detached, the visible area of the structures such as the comb wiper and the dirt suction port on the floor brush assembly can be increased, thereby facilitating the cleaning of the structures such as the comb wiper and the dirt suction port.

[0046] According to one embodiment of the present application, part of the swing member is located below the extension part. The swing member flips to switch the front wiper between the raised position and the lowered position.

[0047] When the swing member flips downward, the elastic member drives the extension part to flip downward, and the front wiper flips upward to reach the raised position.

[0048] When the swing member flips upward, the swing member pushes the extension part to flip upward, and the front wiper flips downward to reach the lowered position.

[0049] In the embodiments of the present application, the swing member can be used to drive the extension portion to turn upward, so that the roller brush cover plate can move in the direction of the second position. The elastic member can be used to drive the extension portion to turn downward, so that the roller brush cover plate can move in the direction of the first position.

[0050] Specifically, when the roller brush cover plate is located at the second position, the swing member and the extension portion abut against each other, and the swing member can constrain the extension portion from turning downward under the action of the motor. The elastic member can cause the extension portion to have a downward turning trend. When the motor drives the swing member to turn downward relative to the brush main body, the constraint force of the swing member on the extension portion gradually decreases. The elastic member can release the elastic force to cause the extension portion to turn downward, so that the front scraping strip can be lifted upward to have a spacing with the surface to be cleaned, and the roller brush cover plate reaches the first position.

[0051] During the movement of the roller brush cover plate from the second position to the first position, the swing member and the extension portion can remain abutting against each other. When the motor drives the swing member to turn upward relative to the brush main body, the swing member can push the extension portion to turn upward, so that the front scraping strip can be lowered to be in contact with the surface to be cleaned, and the roller brush cover plate reaches the second position.

[0052] According to an embodiment of the present application, in the axial direction of the roller brush, the elastic member is located in the middle region of the roller brush cover plate, one end of the elastic member abuts against the upper cover body, and the other end of the elastic member abuts against the extension portion.

[0053] In the embodiments of the present application, the elastic member can be used to drive the extension portion to turn downward, so that the roller brush cover plate moves to the first position. By arranging the elastic member in the middle region of the roller brush cover plate in the axial direction of the roller brush, the elastic force acting on the two end portions of the roller brush cover plate away from the middle region can be relatively uniform, so that the roller brush cover plate can turn smoothly.

[0054] According to an embodiment of the present application, when the roller brush cover plate switches between the first position and the second position, the upper cover body remains fixed relative to the brush main body.

[0055] In the embodiments of the present application, by arranging the upper cover body to remain fixed relative to the brush main body, the upper cover body can remain fixed relative to the brush main body during the turning of the roller brush cover plate. In other words, the upper cover body does not move synchronously with the roller brush cover plate during the turning of the roller brush cover plate. In this way, the synchronous movement of the upper cover body and the roller brush cover plate can be reduced, which reduces the possibility that the upper cover body and the brush main body are easily rubbed and collided or produce abnormal sound. In addition, the synchronous movement of the upper cover body and the brush main body also increases the driving resistance of the swing member and the elastic member, thereby affecting the reliability of the switching of the roller brush cover plate between the first position and the second position.

[0056] According to one embodiment of the present application, the upper cover body is provided with a first connecting portion and a second connecting portion for detachable connection with the floor brush body.

[0057] The first connecting portion is close to an end of the floor brush body along the axial direction of the roller brush, and the second connecting portion is close to the elastic member.

[0058] In the embodiments of the present application, the first connecting portion and the second connecting portion can be used to realize the detachable connection of the front scraping strip assembly with the floor brush body.

[0059] The one end of the elastic member abuts against the inner wall of the upper cover body, the other end of the elastic member abuts against the extension portion, and the elastic force of the elastic member makes the extension portion always have a downward overturning movement trend. Therefore, there is a relative force between the upper cover body and the elastic member. The elastic member has an upward pushing force on the upper cover body. By arranging the second connecting portion close to the elastic member, the second connecting portion can improve the connection reliability of the upper cover body with the floor brush body, and reduce the possibility of the upward force of the elastic member on the upper cover body causing the upper cover body to deform away from the floor brush body.

[0060] By arranging the first connecting portion close to the end of the floor brush body along the axial direction of the roller brush, the connection reliability of the end of the upper cover body with the floor brush body can be improved. Therefore, along the axial direction of the roller brush, the first connecting portion and the second connecting portion can improve the connection reliability of the front scraping strip assembly with the upper cover body in the middle region and the edge region, which is beneficial to improve the connection reliability of the front scraping strip assembly with the floor brush body.

[0061] In a third aspect, the present application provides a floor brush assembly, which comprises:

[0062] a floor brush body;

[0063] a roller brush arranged in the floor brush body, the roller brush rotating for cleaning a surface to be cleaned;

[0064] a front scraping strip assembly detachably connected to the floor brush body, the front scraping strip assembly comprising a roller brush cover plate, a front scraping strip and an upper cover body, the roller brush cover plate covering at least part of the roller brush, the front scraping strip being arranged on the roller brush cover plate and located at the front side of the roller brush along the forward pushing direction of the floor brush assembly, the roller brush cover plate having an extension portion away from the front scraping strip;

[0065] a driving assembly arranged in the floor brush body, the driving assembly being used to drive the roller brush cover plate to overturn forward or reverse to have a first position and a second position, the driving assembly comprising a motor and a swing member, the motor being connected with the swing member, and the swing member corresponding to the extension portion;

[0066] When the front wiping strip or the rolling brush cover plate touches an obstacle during the process of pushing the floor brush assembly forward, the rolling brush cover plate is flipped from the first position to the second position under the blocking of the obstacle, and the extension of the rolling brush cover plate is flipped upward to be separated from the swing member;

[0067] The height of the front wiping strip when the rolling brush cover plate is in the first position is higher than the height of the front wiping strip when the rolling brush cover plate is in the second position, and the front wiping strip is in contact with the surface to be cleaned when the rolling brush cover plate is in the second position.

[0068] In the embodiments of the present application, when the rolling brush cover plate is flipped from the first position to the second position, the extension can be flipped upward. By setting the extension to be separated from the swing member, the possibility of the extension driving the swing member to flip upward synchronously and causing the motor connected with the swing member to operate reversely can be reduced, thereby affecting the working performance and service life of the motor.

[0069] Specifically, during the process of pushing the floor brush assembly forward, the rolling brush cover plate can be in the first position. When the floor brush assembly touches an obstacle such as a wall, the wall applies a force to the rolling brush cover plate towards the rolling brush, so that the front wiping strip is lowered to be in contact with the surface to be cleaned. During the process of lowering the front wiping strip, the extension can be flipped upward, and the extension can be separated from and away from the swing member. In other words, the extension and the swing member can not be connected. The movement between the extension and the swing member can be independent of each other. Therefore, the swing member can remain stationary to reduce the possibility of the swing member moving synchronously with the extension and affecting the operation of the motor.

[0070] When the extension is flipped upward to make the rolling brush cover plate be in the second position, the extension and the swing member can have the maximum spacing therebetween. At this time, since the floor brush assembly cannot move forward due to the obstacle, the floor brush assembly can perform a backward pulling movement. When the floor brush assembly is pulled backward, the motor can drive the swing member to flip upward to abut against the extension again, so that the front wiping strip can be kept in the second position during the backward pulling movement of the floor brush assembly. The front wiping strip can carry the dirt at the edge of the bottom of the wall away and suck it into the floor brush body through the dirt suction port.

[0071] According to an embodiment of the present application, the extension and the swing member have an abutting state and a separated state therebetween;

[0072] When the floor brush assembly is pushed forward and the front wiping strip or the rolling brush cover plate does not touch an obstacle, the extension and the swing member are in the abutting state therebetween;

[0073] When the front of the floor brush assembly does not touch an obstacle and the floor brush assembly is pulled backward, the extension and the swing member are in the abutting state therebetween;

[0074] When the brush assembly is pushed forward and the obstacle makes the roll brush cover plate flip in the direction of the second position, the extension part and the swing part are in the separated state.

[0075] In the embodiment of the present application, when the brush assembly is pushed forward and the obstacle makes the roll brush cover plate flip in the direction of the second position, the extension part and the swing part are in the separated state.

[0076] When the brush assembly is pushed forward and the obstacle makes the roll brush cover plate flip in the direction of the second position, the extension part and the swing part are in the separated state.

[0077] When the brush assembly is pushed forward and the obstacle makes the roll brush cover plate flip in the direction of the second position, the extension part and the swing part are in the separated state.

[0078] In addition, since the extension part and the swing part can be in the separated state, the front scraper assembly can be disassembled. It should be noted that during disassembly, the swing motor and other structures do not need to be disassembled, which is conducive to the quick and convenient disassembly of the front scraper assembly.

[0079] According to an embodiment of the present application, the driving assembly comprises an elastic member, which is located between the upper cover body and the extension part.

[0080] When the roll brush cover plate is flipped in the direction of the second position under the blocking action of the obstacle, the elastic member is used to buffer the action force of the obstacle.

[0081] When the brush assembly is pushed forward and the obstacle makes the roll brush cover plate flip in the direction of the second position, the extension part and the swing part are in the separated state.

[0082] In the embodiment of the present application, when the rolling brush cover plate contacts the obstacle, the obstacle and the rolling brush cover plate have a relative force. The obstacle exerts a force on the rolling brush cover plate towards the rolling brush, so that the front scraping strip is lowered and the extension is turned upward. By arranging the elastic member, the extension can be slowly turned upward. The elastic member can buffer the collision force of the obstacle on the rolling brush cover plate, so as to reduce the possibility of damage to the rolling brush cover plate, and facilitate to improve the service life of the rolling brush cover plate.

[0083] Specifically, in the process of turning upward, the elastic member can buffer the force of upward movement of the extension, so as to reduce the possibility of collision between the extension and the upper cover of the rolling brush. Moreover, the elastic member can make the extension move upward slowly, and the part of the rolling brush cover plate located on the front side of the rolling brush can be in close contact with the rolling brush, so as to release the collision force of the obstacle on the rolling brush cover plate to the rolling brush. Thus, the collision force of the rolling brush cover plate on the wall can be buffered by the relatively soft bristles on the rolling brush, and the possibility of damage to the rolling brush cover plate can be reduced.

[0084] According to an embodiment of the present application, when the rolling brush cover plate is located at the first position, there is a gap between the inner wall of the rolling brush cover plate and the rolling brush.

[0085] When the rolling brush cover plate is located at the second position, the inner wall of the rolling brush cover plate is in contact with the rolling brush.

[0086] In the embodiment of the present application, when the rolling brush cover plate is located at the first position, the gap between the inner wall of the rolling brush cover plate and the rolling brush can make the front scraping strip have a spacing from the surface to be cleaned, so that the large-particle dirt can be sucked into the floor brush assembly under the suction force of the suction port.

[0087] When the floor brush assembly contacts the obstacle such as a wall and is in close contact with the wall, the rolling brush cover plate is located at the second position, and part of the rolling brush can be in contact with the inner wall of the rolling brush cover plate, so as to reduce the distance between the rolling brush and the wall, thereby reducing the cleaning dead angle of the rolling brush on the surface to be cleaned. Moreover, the inner wall of the rolling brush cover plate and the rolling brush can be in contact with each other, so as to release the collision force of the obstacle on the rolling brush cover plate to the rolling brush. Thus, the collision force of the rolling brush cover plate on the wall can be buffered by the relatively soft bristles on the rolling brush, and the possibility of damage to the rolling brush cover plate can be reduced.

[0088] According to an embodiment of the present application, the side of the rolling brush cover plate towards the rolling brush is provided with a sealing member, the sealing member extends along the axial direction of the rolling brush, the sealing member is in contact with the rolling brush, and the sealing member is close to the floor brush body, so as to block the liquid on the rolling brush from entering the floor brush body.

[0089] In the embodiments of the present application, when the brush assembly is pushed forward, the roller brush cover plate is in the first position. There is a gap between the inner wall of the roller brush cover plate and the roller brush. By arranging the sealing member, the dirt on the surface to be cleaned or the liquid (including sewage and clean water) on the roller brush can be reduced during the rotation of the roller brush.

[0090] In a fourth aspect, the embodiments of the present application provide a cleaning device, which comprises:

[0091] The body and the brush assembly in any of the above embodiments. The brush assembly is connected to the body.

[0092] In a fifth aspect, the embodiments of the present application provide a cleaning system, which comprises a base or a base station and a cleaning device that can be placed on the base or the base station.

[0093] The brush assembly provided by the present application has the following beneficial effects: the roller brush cover plate can be flipped relative to the brush main body to lift or lower the front scraping strip. When the brush assembly is pushed forward, the front scraping strip can be controlled to be lifted to clean the water stains on the surface to be cleaned by the roller brush and the rear scraping strip. When the brush assembly is pulled backward, the front scraping strip can be controlled to be lowered to clean the water stains on the surface to be cleaned by the roller brush and the front scraping strip, thereby improving the cleaning efficiency and the cleaning effect and improving the user experience.

[0094] In addition, when the brush assembly encounters an obstacle, the collision of the obstacle causes the roller brush cover plate to flip downward, and the front side of the front scraping strip can be tightly attached to the bottom of the obstacle to reduce the sanitary dead angle of the edge of the bottom of the obstacle, improve the cleaning area, and improve the cleaning effect.

[0095] In addition, when the brush assembly encounters an obstacle, the roller brush cover plate is blocked and flips downward, and the elastic member can buffer the impact of the collision of the obstacle on the roller brush cover plate, thereby reducing the damage to the roller brush cover plate and prolonging the service life of the roller brush cover plate.

[0096] In addition, when the brush assembly encounters an obstacle, the roller brush cover plate is blocked and flips downward, and the extension part is flipped upward and disconnected from the power source to avoid reverse driving of the power source.

[0122] The specific embodiments of the present application have been shown and described in the above-described drawings, and will be described in more detail hereinafter. The drawings and the written description are not intended to restrict the scope of the present application in any way, but to explain the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0123] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The same or similar components are denoted by the same or similar reference numerals throughout the drawings and the written description, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not meant to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims. It should be apparent that the described embodiments are merely a portion of the embodiments consistent with the present application, and not all embodiments consistent with the present application. Based on the embodiments disclosed in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of the present application.

[0124] The cleaning device provided by the embodiments of the present application can be, but is not limited to, a scrubber. The embodiments of the present application take the scrubber as an example. The scrubber is a device for cleaning the ground, which generally comprises a ground brush assembly, a rolling brush, a clean water tank, a sewage tank and the like. The working principle of the scrubber is as follows: through the high-speed rotation of the motor, the rolling brush is driven to rotate at a high speed, and at the same time, the clean water tank is operated to spray clean water onto the rolling brush through a water channel. Through the high-speed rotation of the rolling brush, the sewage and the like are sucked into the sewage tank through another water channel located behind the rolling brush, so as to complete the cleaning process.

[0125] In the forward pushing direction of the scrubber, the rear of the roller brush is usually provided with a scraping strip. The scraping strip can be used to scrape off the water stains left on the surface to be cleaned by the roller brush when the cleaning device is pushed forward, so as to reduce water marks and improve cleaning efficiency. However, when the cleaning device is pulled backward, the roller brush will also leave water stains on the surface to be cleaned. In the related art, by using a roller brush material that can better dissolve water, or by reducing the water output of the water pump to reduce the generation of water stains, the problem of residual water stains when the cleaning device is pulled backward cannot be well solved. Especially when the roller brush is worn out after long-term use, the water stains generated when the cleaning device is pulled backward increase significantly, thereby increasing the drying time of the surface to be cleaned and reducing the user's experience.

[0126] Based on the above technical problems, the applicant improves the structure of the existing brush assembly. In the embodiment of the present application, the front side of the roller brush is provided with a front scraping strip in the forward pushing direction of the brush assembly. Therefore, when the brush assembly is pulled backward, the roller brush can first clean the surface to be cleaned, and then the front scraping strip can scrape off the water stains left on the surface to be cleaned by the roller brush, so as to reduce or eliminate the water stains generated after the surface to be cleaned is dried, and the cleaning efficiency can be improved.

[0127] In addition, the front scraping strip is arranged on the roller brush cover plate, and the roller brush cover plate can be flipped relative to the brush main body to have a first position and a second position, so that the front scraping strip can be lifted to have a distance from the surface to be cleaned, and the front scraping strip can also be lowered to be in contact with the surface to be cleaned. Therefore, when the brush assembly is pushed forward, the front scraping strip can have a distance from the surface to be cleaned, so as to reduce the possibility that the front scraping strip pushes the dirt on the surface to be cleaned away from the dirt suction port of the brush assembly, thereby affecting the cleaning effect. When the brush assembly is pulled backward, the front scraping strip is in contact with the surface to be cleaned, and the front scraping strip can scrape off the water stains left on the surface to be cleaned by the roller brush, so as to improve the cleaning effect and the cleaning efficiency.

[0128] The brush assembly 100, the cleaning device and the cleaning system provided by the present application will be described below with reference to the accompanying drawings and in combination with specific embodiments.

[0129] Referring to Figures 1 to 4 The brush assembly 100 of the embodiment of the present application can include a brush main body 110, a roller brush 120, a front scraping strip assembly 130 and a driving assembly 140.

[0130] The roller brush 120 is arranged on the brush main body 110. The roller brush 120 rotates for cleaning the surface to be cleaned. The front scraping strip assembly 130 can include a roller brush cover plate 131, a front scraping strip 132 and an upper cover body 133.

[0131] The roller brush cover 131 covers at least a portion of the roller brush 120. The roller brush cover 131 has a first position and a second position. A front scraper 132 is disposed on the roller brush cover 131 and is located in front of the roller brush 120 along the forward pushing direction of the floor brush assembly 100. When the floor brush assembly 100 is pushed forward, the roller brush cover 131 is in the first position, and the front scraper 132 is spaced from the surface to be cleaned. In other words, the front scraper 132 can be raised to create a gap between it and the surface to be cleaned. When the floor brush assembly 100 is pulled back, the roller brush cover 131 is in the second position, and the front scraper 132 contacts the surface to be cleaned. In other words, the front scraper 132 can be lowered to contact the surface to be cleaned for cleaning.

[0132] The upper cover 133 is disposed on the brush body 110. The roller brush cover 131 has an extension 1311. The upper cover 133 has a receiving space 133a for accommodating the extension 1311. When the roller brush cover 131 switches between a first position and a second position, the extension 1311 can be flipped within the receiving space 133a.

[0133] A drive assembly 140 is disposed on the brush body 110. The drive assembly 140 is used to drive the roller brush cover 131 to flip forward or backward, so that the roller brush cover 131 has a first position and a second position. The drive assembly 140 includes an elastic element 141. The elastic element 141 is used to give the roller brush cover 131 a tendency to flip.

[0134] In this embodiment, the roller brush cover 131 can rotate relative to the floor brush body 110 to have a first position and a second position. When the floor brush assembly 100 is pushed forward, the suction port of the floor brush assembly 100 sucks up dirt in front. The roller brush cover 131 can be in the first position, so that the front scraper 132 is raised to have a gap between it and the surface to be cleaned. At this time, the front scraper 132 will not push the dirt on the surface to be cleaned forward away from the suction port. Furthermore, the front scraper 132 will not obstruct the suction effect of the floor brush assembly 100 on the dirt in front. Larger particles of dirt on the surface to be cleaned can be cleaned by the roller brush 120 through the gap between the front scraper 132 and the surface to be cleaned.

[0135] When the floor brush assembly 100 is pulled back, the roller brush cover 131 can be in a second position, allowing the front scraper 132 to descend and contact the surface to be cleaned. As the floor brush assembly 100 is pulled back, the front scraper 132 can remove water stains from the cleaned surface after the roller brush 120 has cleaned it, and the front scraper 132 can also move the dirt between itself and the roller brush 120 backward, thereby reducing cleaning dead spots in front of the roller brush 120.

[0136] When the floor brush assembly 100 is pushed forward to touch a wall or other obstacle, the rolling brush cover plate 131 contacts the wall to have an interaction force. The rolling brush cover plate 131 can be flipped to the direction of the first position under the action of the wall, so that the front scraping strip 132 is lowered to contact the surface to be cleaned. The front scraping strip 132 can be attached to the wall, and there can be no gap between the front scraping strip 132 and the wall. With the rear pulling movement of the floor brush assembly 100, the front scraping strip 132 can drive the dirt at the bottom edge of the wall rearward and clean the dirt through the dirt suction port, so as to reduce the sanitary dead angle at the edge position of the wall, improve the cleaning area, and thus improve the cleaning effect.

[0137] Since the rolling brush cover plate 131 can be flipped relative to the floor brush body 110, the extension part 1311 of the rolling brush cover plate 131 can be flipped upward or downward relative to the floor brush body 110. The accommodation space 133a of the upper cover body 133 can provide a movable space for the upward or downward flipping of the extension part 1311, so that the upward or downward flipping of the extension part 1311 is not easily limited, so that the rolling brush cover plate 131 can be switched between the first position and the second position.

[0138] The driving assembly 140 can be used to provide driving force for the flipping of the rolling brush cover plate 131. The elastic member 141 can make the rolling brush cover plate 131 have a flipping movement trend, so that the rolling brush cover plate 131 can be switched between the first position and the second position. Since the elastic member 141 has elasticity, the accumulation or release of elastic force by the elastic member 141 can be used to provide driving force for the flipping of the rolling brush cover plate 131. Moreover, since the elastic member 141 has elasticity, the elastic member 141 can have a buffering effect, so that the rolling brush cover plate 131 can move stably during flipping, which is beneficial to improve the service life and movement reliability of the rolling brush cover plate 131.

[0139] It should be noted that the elastic member 141 can drive the rolling brush cover plate 131 to move in the direction from the first position to the second position by elastic force, or the elastic member 141 can also drive the rolling brush cover plate 131 to move in the direction from the second position to the first position by elastic force, which is not limited in the embodiment.

[0140] In some examples, according to the user's regular use habit, the floor brush assembly 100 remains in the forward pushing movement more than in the rear pulling movement. For example, when touching the wall or other obstacle, the floor brush assembly 100 can be pulled rearward. Therefore, the rolling brush cover plate 131 can be kept in the first position for a long time to ensure the cleaning effect on the surface to be cleaned when the floor brush assembly 100 is pushed forward.

[0141] In some examples, the upper cover body 133 can remain stationary relative to the floor brush body 110 during the flipping of the rolling brush cover plate 131.

[0142] In some possible implementations, referring to Figure 2 and Figure 4 shown, the extension 1311 and the front wiper 132 of the embodiment of the application are respectively located at two ends of the roller brush cover plate 131. When the extension 1311 is flipped downward, the front wiper 132 is flipped upward, and the roller brush cover plate 131 moves in the direction of the first position. When the extension 1311 is flipped upward, the front wiper 132 is flipped downward, and the roller brush cover plate 131 moves in the direction of the second position.

[0143] In the embodiment of the application, the roller brush cover plate 131 can be flipped relative to the floor brush body 110. By arranging the extension 1311 and the front wiper 132 at two ends of the roller brush cover plate 131, the flipping of the entire roller brush cover plate 131 can be realized by driving the extension 1311 to flip upward or downward, so as to realize the flipping of the front wiper 132 upward or downward.

[0144] It is easy to understand that, since the extension 1311 is located at the end of the roller brush cover plate 131, the driving assembly 140 can exert a force on the end of the extension 1311 away from the front wiper 132, so as to realize a larger movement amplitude of the roller brush cover plate 131 by a smaller driving force.

[0145] In some examples, the roller brush cover plate 131 can be rotated relative to the floor brush body 110 through the rotating shaft 134. The rotating shaft 134 is located on the roller brush cover plate 131 and between the extension 1311 and the front wiper 132. In other words, the extension 1311 and the front wiper 132 are located on two sides of the rotating shaft 134, so that, when the extension 1311 is flipped downward, the roller brush cover plate 131 can be rotated relative to the rotating shaft 134 to realize the flipping of the front wiper 132 upward. Similarly, when the extension 1311 is flipped upward, the roller brush cover plate 131 can be rotated relative to the rotating shaft 134 to realize the flipping of the front wiper 132 downward.

[0146] In some examples, the position of the rotating shaft 134 on the roller brush cover plate 131 extending away from the front wiper 132 can form the extension 1311.

[0147] In some examples, the roller brush cover plate 131 can be rotationally connected with the floor brush body 110 through the rotating shaft 134 to realize the flipping of the roller brush cover plate 131. Alternatively, the roller brush cover plate 131 can also be rotationally connected with the upper cover body 133 through the rotating shaft 134. In the embodiment, no limitation is made.

[0148] In some possible implementations, referring to Figure 3 shown, the elastic member 141 of the embodiment of the application abuts against the extension 1311. The elastic member 141 exerts a force on the extension 1311 towards the surface to be cleaned, so as to flip the extension 1311 downward, and the roller brush cover plate 131 has a movement tendency of flipping to the first position.

[0149] In this embodiment, the elastic element 141 can be used to drive the roller brush cover 131 to flip in the direction of the first position. The elastic element 141 can drive the extension 1311 to flip downward by elastic force, so that the front scraper 132 can flip upward, thereby raising the front scraper 132 to a distance from the surface to be cleaned.

[0150] Specifically, when the floor brush assembly 100 is pushed forward, the elastic member 141 can maintain the downward-flipped state of the pushing extension 1311, so that there is always a gap between the front scraper 132 and the surface to be cleaned, so that dirt on the front side of the roller brush 120 can be sucked into the suction port. When the floor brush assembly 100 is pulled back, the upward flipping of the extension 1311 can cause the elastic member 141 to undergo elastic deformation, and the front scraper 132 descends to contact the surface to be cleaned. At this time, the elastic member 141 can accumulate elastic force, so that the extension 1311 can always have a downward flipping movement tendency.

[0151] See also some of the possible implementation methods. Figure 2 and Figure 4 As shown, in this embodiment of the application, the elastic member 141 is located in the receiving space 133a. One end of the elastic member 141 abuts against the upper cover 133, and the other end of the elastic member 141 abuts against the extension 1311.

[0152] In this embodiment, the elastic member 141 may be located within the space between the extension 1311 and the upper cover 133. The upper end of the elastic member 141 may abut against the surface of the upper cover 133 facing the extension 1311. The lower end of the elastic member 141 may abut against the upper surface of the extension 1311. When the roller brush cover 131 is in the second position, the elastic member 141 undergoes compressive deformation under the relative action of the extension 1311 and the upper cover 133. There is an interaction force between the extension 1311 and the elastic member 141, so that the elastic member 141 can accumulate elastic force, thereby providing a tendency for the extension 1311 to flip downward.

[0153] See also some of the possible implementation methods. Figure 2 and Figure 4 As shown, the drive assembly 140 in this embodiment of the application also includes a swing member 142. The swing member 142 flips relative to the brush body 110.

[0154] The swing member 142 is used to push the extension 1311 upward when it flips upward and comes into contact with the extension 1311. Furthermore, the swing member 142 can be used to release the force of the elastic member 141 when it flips downward, causing the extension 1311 to flip downward.

[0155] In the embodiments of the present application, the swing member 142 can be used to drive the extension 1311 to move. When the mop assembly 100 is pulled backward, the swing member 142 can be flipped upward. By abutting the swing member 142 against the extension 1311, the extension 1311 can be flipped upward synchronously with the swing member 142 during the flipping process of the swing member 142, so that the front scraping strip 132 can be lowered to contact the surface to be cleaned, thereby cleaning the surface to be cleaned.

[0156] During the flipping process of the swing member 142 to flip the extension 1311 upward, the elastic member 141 can be compressed. When the swing member 142 is flipped upward to the second position of the roller brush cover plate 131, the elastic force accumulated in the elastic member 141 can make the extension 1311 have a tendency to flip downward. At this time, the force of the swing member 142 to flip the extension 1311 upward is greater than the elastic force of the elastic member 141, so that the roller brush cover plate 131 can be kept in the second position. When the swing member 142 is flipped downward, the abutting force of the swing member 142 on the extension 1311 can gradually decrease. When the elastic potential energy generated by the elastic member 141 is greater than the abutting force of the swing member 142 on the extension 1311, the elastic member 141 can drive the extension 1311 to flip downward, so that the roller brush cover plate 131 can move to the first position.

[0157] It should be noted that, as shown in Figure 5 and Figure 5a , the swing member 142 and the extension 1311 have an abutting state, and can also have a separated state. In other words, the driving force of the extension 1311 to flip upward is not limited to the upward flipping of the swing member 142.

[0158] For example, the driving force of the extension 1311 to flip upward can come from the wall or other obstacles. When the mop assembly 100 is pushed forward to touch the wall or other obstacles, the wall contacts the roller brush cover plate 131 and applies a force to the roller brush cover plate 131. The roller brush cover plate 131 can flip to move, so that the front scraping strip 132 is lowered to contact the surface to be cleaned, and the extension 1311 can overcome the elastic force of the elastic member 141 to flip upward. At this time, the extension 1311 can be separated from the swing member 142. The roller brush cover plate 131 moves in the direction of the second position.

[0159] When the mop assembly 100 is pushed forward to touch the wall or other obstacles, the wall contacts the roller brush cover plate 131 and applies a force to the roller brush cover plate 131. The roller brush cover plate 131 flips downward, synchronously making the extension 1311 flip upward, and at this time the extension 1311 is separated from the swing member 142, so that the motor 143 is not reversely driven by the swing member 142 to reversely drive the motor 143, thereby protecting the motor 143 and prolonging the service life of the motor 143.

[0160] When the extension 1311 is separated from the swing piece 142, the downward overturning of the roller brush cover plate 131 does not have a dragging chain, and the quick response overturning of the roller brush cover plate 131 to the impact can be realized, and the impact resistance reliability of the lifting structure is improved.

[0161] Wherein, by setting the extension 1311 and the swing piece 142 can be separated, the overall disassembly of the front scraping strip assembly 130 can be realized, so as to facilitate the cleaning of the comb teeth scraping strip and the dirt suction port on the floor brush assembly 100.

[0162] When the floor brush assembly 100 is pushed to the wall and cannot continue to be pushed forward, the roller brush cover plate 131 can be in the second position. At this time, the floor brush assembly 100 can only be pulled backward. Since the front scraping strip 132 can be attached to the wall, with the backward pulling movement of the floor brush assembly 100, the front scraping strip 132 can clean the dirt on the wall corner edge and other areas. It should be noted that after the roller brush cover plate 131 is in the second position, the swing piece 142 can be controlled to overturn upward to abut against the extension 1311, so that when the wall force on the roller brush cover plate 131 gradually decreases to disappear during the backward pulling movement of the floor brush assembly 100, the swing piece 142 can keep the roller brush cover plate 131 in the second position, so as to reduce the possibility of causing secondary pollution caused by the movement of the roller brush cover plate 131 from the second position to the first position, and the upward overturning of the front scraping strip 132 to throw the dirt in the direction of the wall.

[0163] In an implementable manner, referring to Figure 2 and Figure 4 Since the roller brush cover plate 131 overturns relative to the floor brush main body 110 to have the first position and the second position, when the roller brush cover plate 131 is in the first position, there is a gap between the inner wall of the roller brush cover plate 131 and the roller brush 120. Through the above gap, the front scraping strip 132 and the surface to be cleaned have a spacing, so that the large-particle dirt can be sucked into the floor brush assembly 100 under the suction force of the dirt suction port.

[0164] When the floor brush assembly 100 touches the wall and other obstacles and is attached to the wall, the roller brush cover plate 131 is in the second position, and part of the roller brush 120 can be in contact with the inner wall of the roller brush cover plate 131, so as to reduce the distance between the roller brush 120 and the wall, thereby reducing the cleaning dead angle of the roller brush 120 to the surface to be cleaned. Moreover, through the mutual contact between the inner wall of the roller brush cover plate 131 and the roller brush 120, the impact force of the obstacle on the roller brush cover plate 131 can be released to the roller brush 120, so that the relatively soft bristles on the roller brush 120 can buffer the impact force of the wall on the roller brush cover plate 131, thereby reducing the possibility of damage to the roller brush cover plate 131.

[0165] In some examples, the ends of the extension 1311 and the swing member 142 that are close to each other may abut against each other. Exemplarily, the end of the swing member 142 may be located below the end of the extension 1311.

[0166] In some examples, the extension 1311 and the swing member 142 can abut against each other via an adapter post 135. The adapter post 135 has a smooth arc surface, which can improve the smoothness of the fit between the extension 1311 and the swing member 142 and reduce the possibility of jamming or getting stuck.

[0167] In some examples, the position where the elastic element 141 abuts against the extension 1311 can be close to the adapter post 135. For example, the abutment position of the elastic element 141 on the extension 1311 can be located in the intermediate region between the rotating shaft 134 and the adapter post 135.

[0168] In some examples, the drive assembly 140 may also include a power source. The power source can be used to drive the oscillating member 142 to flip up or down. Exemplarily, the power source may be a motor 143.

[0169] It should be noted that since the power source drives the swing member 142 to move, by setting the extension 1311 to be separable from the swing member 142, the possibility of the extension 1311 driving the swing member 142 to rotate upward synchronously when it rotates upward, thereby causing the swing member 142 to drive the power source to move, which may lead to the power source being prone to failure, affecting the working performance and service life of the power source.

[0170] In some examples, the motor 143 may be mounted on the brush body 110.

[0171] See also some of the possible implementation methods. Figure 2 and Figure 4 As shown, in this embodiment, the lever arm length of the extension 1311 relative to the rotation axis 134 of the roller brush cover 131 is less than the lever arm length of the front scraper 132 relative to the rotation axis 134 of the roller brush cover 131.

[0172] In this embodiment, the roller brush cover 131 can be flipped by the pushing or releasing action of the swing member 142 on the extension 1311. Therefore, the force-applying end of the roller brush cover 131's flipping movement is located in the extension 1311. By setting the lever arm length of the extension 1311 relative to the rotation axis 134 to be smaller than the lever arm length of the front scraper 132 relative to the rotation axis 134, the lever arm length of the force-applying end can be smaller, thereby achieving a larger flipping amplitude at one end of the front scraper 132 with a smaller movement amplitude at the force-applying end. With a fixed movement amplitude of the front scraper 132, it is beneficial to save the accommodating space 133a of the upper cover 133 and reduce the volume of the floor brush assembly 100.

[0173] In some possible implementations, referring to Figure 2 and Figure 4 The sealing member 150 is arranged on the side of the brush cover plate 131 facing the brush 120. The sealing member 150 extends along the axial direction of the brush 120. The sealing member 150 is in contact with the brush 120. The sealing member 150 is close to the floor brush body 110, so as to block the liquid on the brush 120 from entering the floor brush body 110.

[0174] In the embodiment, when the floor brush assembly 100 is pushed forward, the brush cover plate 131 is in the first position. There is a gap between the inner wall of the brush cover plate 131 and the brush 120. By arranging the sealing member 150, the phenomenon that the dirt on the surface to be cleaned or the liquid (including sewage and clean water) on the brush 120 is rolled into the floor brush body 110 during the rotation of the brush 120 can be avoided.

[0175] In some examples, the position of the sealing strip on the brush cover plate 131 can correspond to the upper region of the brush 120.

[0176] The embodiment provides a floor brush assembly 100, referring to Figure 4 The floor brush assembly 100 can include a floor brush body 110, a brush 120, a front wiping strip assembly 130 and a driving assembly 140.

[0177] The brush 120 is arranged on the floor brush body 110. The brush 120 rotates to clean the surface to be cleaned.

[0178] The front wiping strip assembly 130 is detachably connected to the floor brush body 110. The front wiping strip assembly 130 includes a brush cover plate 131, a front wiping strip 132 and an upper cover body 133. The brush cover plate 131 covers at least part of the brush 120. The front wiping strip 132 is arranged on the brush cover plate 131 and is located on the front side of the brush 120 in the forward pushing direction of the floor brush assembly 100. The upper cover body 133 is arranged on the floor brush body 110.

[0179] The driving assembly 140 is arranged on the floor brush body 110. The driving assembly 140 is used to drive the brush cover plate 131 to flip up and down to have a first position and a second position. The driving assembly 140 includes a motor 143, a swing member 142 and an elastic member 141. The motor 143 is connected with the swing member 142. The brush cover plate 131 has an extension 1311 away from the front wiping strip 132. The elastic member 141 is connected with the extension 1311, so as to apply a force to the extension 1311. The bottom of the extension 1311 is in abutment with the swing member 142.

[0180] When the floor brush assembly 100 is pushed forward, the rolling brush cover plate 131 is in the first position, and the front scraping strip 132 is in the raised position. When the floor brush assembly 100 is pulled backward, the rolling brush cover plate 131 is in the second position, and the front scraping strip 132 is in the lowered position and in contact with the surface to be cleaned.

[0181] In the embodiment, the abutment of the swing member 142 and the extension 1311 can drive the rolling brush cover plate 131 to flip relative to the floor brush body 110 and switch between the first position and the second position through the cooperation between the swing member 142 and the extension 1311. In addition, the detachable connection of the front scraping strip assembly 130 and the floor brush body 110 can be achieved. Specifically, the detachability of the front scraping strip assembly 130 can facilitate the cleaning of the inner wall of the rolling brush 120 and the inner wall of the rolling brush cover plate 131. In addition, after the front scraping strip assembly 130 is detached, the visible area of the rolling brush 120 can be increased to facilitate the user to detach the rolling brush 120. In addition, after the rolling brush 120 is detached, the visible area of the comb tooth scraping strip, the dirt suction port and other structures on the floor brush assembly 100 can be increased to facilitate the cleaning of the comb tooth scraping strip, the dirt suction port and other structures.

[0182] In some possible implementation manners, as shown in Figure 4 The swing member 142 is located below the extension 1311. The swing member 142 flips to switch the front scraping strip 132 between the raised position and the lowered position.

[0183] When the swing member 142 flips downward, the elastic member 141 drives the extension 1311 to flip downward, and the front scraping strip 132 flips upward to reach the raised position. When the swing member 142 flips upward, the swing member 142 pushes the extension 1311 to flip upward, and the front scraping strip 132 flips downward to reach the lowered position.

[0184] In the embodiment, the swing member 142 can be used to drive the extension 1311 to flip upward, so that the rolling brush cover plate 131 can move in the direction of the second position. The elastic member 141 can be used to drive the extension 1311 to flip downward, so that the rolling brush cover plate 131 can move in the direction of the first position.

[0185] Specifically, when the roller brush cover plate 131 is located at the second position, the swing piece 142 is in abutment with the extension 1311, and the swing piece 142 can constrain the extension 1311 to turn downward under the action of the motor 143. The elastic piece 141 can cause the extension 1311 to have a tendency to turn downward. When the motor 143 drives the swing piece 142 to turn downward relative to the brush body 110, the constraint force of the swing piece 142 on the extension 1311 gradually decreases. The elastic piece 141 can release the elastic force to cause the extension 1311 to turn downward, so that the front scraping strip 132 can be lifted upward to have a spacing with the surface to be cleaned, and the roller brush cover plate 131 reaches the first position.

[0186] During the movement of the roller brush cover plate 131 from the second position to the first position, the swing piece 142 can remain in abutment with the extension 1311. When the motor 143 drives the swing piece 142 to turn upward relative to the brush body 110, the swing piece 142 can push the extension 1311 to turn upward, so that the front scraping strip 132 can be lowered to be in contact with the surface to be cleaned, and the roller brush cover plate 131 reaches the second position.

[0187] In some implementable manners, as shown in Figure 2 , Figure 4 and Figure 5 , along the axial direction of the roller brush 120, the elastic piece 141 is located in the middle region of the roller brush cover plate 131. One end of the elastic piece 141 is in abutment with the upper cover body 133, and the other end of the elastic piece 141 is in abutment with the extension 1311.

[0188] In the embodiment of the application, the elastic piece 141 can be used to drive the extension 1311 to turn downward, so that the roller brush cover plate 131 moves to the first position. By arranging the elastic piece 141 to be located in the middle region of the roller brush cover plate 131 along the axial direction of the roller brush 120, the action force of the elastic piece 141 on the two end portions of the roller brush cover plate 131 away from the middle region can be relatively uniform, so that the roller brush cover plate 131 can stably turn.

[0189] In some examples, the number of elastic pieces 141 can be but is not limited to one. When the elastic piece 141 is one, along the front pushing or rear pulling direction of the brush assembly 100, the swing piece 142 can correspond to the elastic piece 141. The swing piece 142 and the motor 143 can also be located close to the middle region of the roller brush cover plate 131 along the axial direction of the roller brush 120.

[0190] In some examples, along the axial direction of the roller brush 120, the extension 1311 can be located in the middle region of the roller brush cover plate 131.

[0191] In some implementable manners, as shown in Figure 2 and Figure 4As shown, the rolling brush cover plate 131 of the embodiment of the present application keeps the upper cover body 133 fixed relative to the floor brush main body 110 when switching between the first position and the second position.

[0192] In the embodiment of the present application, by setting the upper cover body 133 to keep fixed relative to the floor brush main body 110, the upper cover body 133 can keep fixed relative to the floor brush main body 110 during the flipping process of the rolling brush cover plate 131. In other words, the upper cover body 133 does not move synchronously during the flipping process of the rolling brush cover plate 131. In this way, the synchronous movement of the upper cover body 133 and the rolling brush cover plate 131 can be reduced, which reduces the possibility of friction and collision or abnormal noise between the upper cover body 133 and the floor brush main body 110. In addition, the synchronous movement of the upper cover body 133 and the floor brush main body 110 also increases the driving resistance of the swing member 142 and the elastic member 141, thereby affecting the reliability of the rolling brush cover plate 131 switching between the first position and the second position.

[0193] In some examples, the rolling brush cover plate 131 can be rotatably connected to the upper cover body 133 through the rotating shaft 134.

[0194] In some examples, part of the rolling brush cover plate 131 is located above the rolling brush 120. Part of the upper cover body 133 can be located above the floor brush main body 110. The upper cover body 133 and the floor brush main body 110 can form a containing space 133a, and the volume of the containing space 133a remains unchanged.

[0195] In some examples, the rotating shaft 134 can also be located in the containing space 133a. The upper cover body 133 can cover the extension 1311, the rotating shaft 134, and at least part of the swing member 142, so as to reduce the possibility of entering debris between the extension 1311 and the rotating shaft 134, and between the extension 1311 and the swing member 142, which affects the flexibility of the rolling brush cover plate 131 flipping.

[0196] In some realizable ways, referring to Figures 6 to 9 As shown, the upper cover body 133 is provided with a first connecting part 1331 and a second connecting part 1332 for detachable connection with the floor brush main body 110. Along the axial direction of the rolling brush 120, the first connecting part 1331 is close to the end of the floor brush main body 110, and the second connecting part 1332 is close to the elastic member 141.

[0197] In the embodiment of the present application, the first connecting part 1331 and the second connecting part 1332 can be used to realize the detachable connection of the front scraping strip assembly 130 and the floor brush main body 110.

[0198] One end of the elastic member 141 abuts against the inner wall of the upper cover body 133, and the other end of the elastic member 141 abuts against the extension 1311, and the elastic force of the elastic member 141 causes the extension 1311 to always have a downward overturning trend. Therefore, there is a relative force between the upper cover body 133 and the elastic member 141. The elastic member 141 has a pushing upward force on the upper cover body 133. By arranging the second connecting portion 1332 close to the elastic member 141, the connection reliability of the upper cover body 133 and the brush body 110 can be improved through the second connecting portion 1332, and the upward force of the elastic member 141 on the upper cover body 133 is reduced to reduce the possibility of the upper cover body 133 deforming in a direction away from the brush body 110.

[0199] By arranging the first connecting portion 1331 close to the end of the brush body 110 along the axial direction of the roller brush 120, the connection reliability of the end of the upper cover body 133 and the brush body 110 can be improved. Therefore, along the axial direction of the roller brush 120, the connection reliability of the front scraping strip assembly 130 and the upper cover body 133 in the middle region and the edge region can be improved through the first connecting portion 1331 and the second connecting portion 1332, which is beneficial to improve the connection reliability of the front scraping strip assembly 130 and the brush body 110.

[0200] In some examples, referring to Figures 7 to 9 The upper cover body 133 can be clamped with the brush body 110 through the first connecting portion 1331 and the second connecting portion 1332. For example, the brush body 110 can be provided with a first clamping groove 111 matched with the first connecting portion 1331. The brush body 110 can be provided with a second clamping groove 112 matched with the second connecting portion 1332. During installation of the front scraping strip assembly 130, the first connecting portion 1331 and the first clamping groove 111 can be clamped with each other, and the second connecting portion 1332 and the second clamping groove 112 can be clamped with each other, so as to fix the front scraping strip assembly 130.

[0201] For example, the two sides of the extension 1311 can be respectively provided with a group of first connecting portions 1331 and second connecting portions 1332.

[0202] The embodiment of the present application provides a brush assembly 100, referring to Figure 2 and Figure 4 The brush assembly 100 includes a brush body 110, a roller brush 120, a front scraping strip assembly 130, and a driving assembly 140.

[0203] The rolling brush 120 is arranged on the floor brush body 110. The rolling brush 120 rotates for cleaning the surface to be cleaned. The front wiper assembly 130 is detachably connected to the floor brush body 110. The front wiper assembly 130 comprises a rolling brush cover plate 131, a front wiper 132 and an upper cover body 133. The rolling brush cover plate 131 covers at least part of the rolling brush 120. The front wiper 132 is arranged on the rolling brush cover plate 131 and is located at the front side of the rolling brush 120 along the pushing direction of the floor brush assembly 100. The rolling brush cover plate 131 has an extension 1311 away from the front wiper 132.

[0204] The driving assembly 140 is arranged on the floor brush body 110. The driving assembly 140 is used to drive the rolling brush cover plate 131 to flip forward or reverse to have a first position and a second position. The driving assembly 140 comprises a motor 143 and a swing piece 142. The motor 143 is connected with the swing piece 142. The swing piece 142 corresponds to the extension 1311.

[0205] During the process of pushing the floor brush assembly 100, when the front wiper 132 or the rolling brush cover plate 131 touches the obstacle, the rolling brush cover plate 131 flips from the first position to the second position under the blocking action of the obstacle. The extension 1311 of the rolling brush cover plate 131 flips upward to be separated from the swing piece 142.

[0206] In the embodiment, the height of the front wiper 132 when the rolling brush cover plate 131 is in the first position is higher than the height of the front wiper 132 when the rolling brush cover plate 131 is in the second position. When the rolling brush cover plate 131 is in the second position, the front wiper 132 is in contact with the surface to be cleaned.

[0207] In the embodiment, when the rolling brush cover plate 131 flips from the first position to the second position, the extension 1311 can flip upward. By arranging the extension 1311 to be separated from the swing piece 142, the possibility of the extension 1311 driving the swing piece 142 to flip upward synchronously and causing the motor 143 connected with the swing piece 142 to operate reversely can be reduced, so as to affect the working performance and service life of the motor 143.

[0208] Specifically, during the process of pushing the floor brush assembly 100, the rolling brush cover plate 131 can be in the first position. When the floor brush assembly 100 touches the wall or other obstacle, the wall applies a force to the rolling brush cover plate 131 towards the rolling brush 120, so that the front wiper 132 is lowered to be in contact with the surface to be cleaned. During the process of lowering the front wiper 132, the extension 1311 can flip upward, and the extension 1311 can be separated from and away from the swing piece 142. In other words, the extension 1311 and the swing piece 142 can not be connected. The movement between the extension 1311 and the swing piece 142 can be independent of each other. Therefore, the swing piece 142 can remain stationary, so as to reduce the possibility of the swing piece 142 moving synchronously with the extension 1311 and affecting the operation of the motor 143.

[0209] When the extension 1311 is flipped upward to make the roller brush cover plate 131 located at the second position, the extension 1311 and the swing piece 142 can have the maximum spacing therebetween. At this time, the floor brush assembly 100 can perform a backward pulling movement because the floor brush assembly 100 encounters an obstacle and cannot advance. When the floor brush assembly 100 is pulled backward, the motor 143 can drive the swing piece 142 to flip upward to abut against the extension 1311 again, so that the front scraping strip 132 can be kept at the second position when the floor brush assembly 100 performs the backward pulling movement. The front scraping strip 132 can take the dirt at the edge of the wall bottom away and suck into the floor brush body 110 through the dirt suction port.

[0210] When the front pushing floor brush assembly 100 touches the obstacle such as a wall, the floor brush assembly 100 cannot continue to advance and can only be pulled backward. Since the roller brush cover plate 131 has been flipped downward and the extension 1311 has been flipped upward, the motor 143 only needs to drive the swing piece 142 to flip upward under the premise that the floor brush assembly 100 needs to be pulled backward and the roller brush cover plate 131 is at the second position, the load of the motor 143 is small, the required torque of the motor 143 can be reduced, the energy consumption of the motor 143 can be saved, and the service life of the motor 143 can be prolonged. It is easy to understand that the energy consumption of the motor 143 is reduced, and the endurance of the cleaning equipment can be improved.

[0211] In some examples, the extension 1311 and the swing piece 142 can be connected and disconnected by abutting each other.

[0212] In some realizable ways, referring to FIG. 13B, the extension 1311 and the swing piece 142 have an abutting state and a separated state. Figure 5a

[0213] When the front pushing floor brush assembly 100 and the front scraping strip 132 or the roller brush cover plate 131 do not touch the obstacle, the extension 1311 and the swing piece 142 are in the abutting state. When the front pushing floor brush assembly 100 touches the obstacle and the obstacle makes the roller brush cover plate 131 flip in the direction of the second position, the extension 1311 and the swing piece 142 are in the separated state. When the floor brush assembly 100 is pulled backward, the extension 1311 and the swing piece 142 are in the abutting state.

[0214] ​In this embodiment, when the floor brush assembly 100 is pushed forward without touching an obstacle, the motor 143 can drive the swing member 142 to flip downwards, so that the elastic member 141 can drive the extension 1311 to flip downwards, thereby raising the front scraper 132 to a position with a gap between it and the surface to be cleaned. The floor brush assembly 100 can then suck up dirt from in front of it through the suction port. At this time, the swing member 142 and the extension 1311 are in a state of mutual contact, and the swing member 142 can constrain the maximum downward flipping distance of the extension 1311 to constrain the lifting height of the front scraper 132.

[0215] When the front of the floor brush assembly 100 does not touch an obstacle and the floor brush assembly 100 needs to be pulled back, the motor 143 can drive the swing member 142 to flip upward. With the swing member 142 in contact with the extension 1311, the swing member 142 can drive the extension 1311 to flip upward synchronously, allowing the front scraper 132 to descend and contact the surface to be cleaned. During the backward movement of the floor brush assembly 100, the front scraper 132 can clean water stains on the surface to be cleaned after the roller brush 120 has cleaned it.

[0216] When the push brush assembly 100 encounters an obstacle, there is a relative force between the obstacle and the roller brush cover 131. The obstacle exerts a force on the roller brush cover 131 toward the roller brush 120, causing the front scraper 132 to descend to contact the surface to be cleaned, thereby allowing the extension 1311 to flip upwards. By setting the extension 1311 and the swing member 142 to be in a separated state, the upward flipping of the extension 1311 will not cause the swing member 142 to move upwards synchronously. The movements of the extension 1311 and the swing member 142 are independent of each other. When the brush assembly 100 cannot move forward and is pulled backward, the swing member 142 can be driven by the motor 143 to perform an upward flipping action, thereby reducing the possibility that the extension 1311 will interfere with the operation of the motor 143 and affect the working performance of the motor 143.

[0217] Furthermore, since the extension 1311 and the swing member 142 can be separated, the front scraper assembly 130 can be detached. It should be noted that during disassembly, the swing motor 143 and other structures do not need to be disassembled, which facilitates quick and convenient assembly and disassembly of the front scraper assembly 130.

[0218] For example, the front scraper 132, the roller brush cover 131, and the upper cover 133 can be assembled to form the front scraper assembly 130 and then fixed to the floor brush body 110 by snap-fit, screw-fit, or other means.

[0219] See also some of the possible implementation methods. Figure 3 Figure 3 As shown, the drive assembly 140 includes an elastic element 141 located between the upper cover 133 and the extension 1311.

[0220] The elastic member 141 is used to buffer the force of the obstacle when the rolling brush cover plate 131 is flipped to the second position under the blocking effect of the obstacle. When the front brush assembly 100 is pushed forward and the front squeegee assembly 130 does not touch the obstacle, the elastic member 141 is used to drive the extension 1311 to flip downward, so that the front squeegee 132 flips upward, and the rolling brush cover plate 131 can reach the first position.

[0221] In the embodiment of the present application, when the rolling brush cover plate 131 contacts the obstacle, there is a relative force between the obstacle and the rolling brush cover plate 131. The obstacle exerts a force on the rolling brush cover plate 131 towards the rolling brush 120, so that the front squeegee 132 descends and the extension 1311 flips upward. By arranging the elastic member 141, the extension 1311 can be slowly flipped upward. The elastic member 141 can buffer the collision force of the obstacle on the rolling brush cover plate 131, so as to reduce the possibility of damage to the rolling brush cover plate 131, and is beneficial to improve the service life of the rolling brush cover plate 131.

[0222] Specifically, in the process of flipping upward, the elastic member 141 can buffer the force of the upward movement of the extension 1311, so as to reduce the possibility of collision between the extension 1311 and the upper cover of the rolling brush 120. Moreover, the elastic member 141 can make the extension 1311 move upward slowly, and the part of the rolling brush cover plate 131 located in front of the rolling brush 120 can be attached to the rolling brush 120, so as to release the collision force of the obstacle on the rolling brush cover plate 131 to the rolling brush 120. Thus, the collision force of the rolling brush cover plate 131 on the wall can be buffered by the relatively soft bristles of the rolling brush 120, and the possibility of damage to the rolling brush cover plate 131 can be reduced.

[0223] The embodiment of the present application also provides a cleaning device. The cleaning device can include a brush assembly 100 and a machine body.

[0224] The brush assembly 100 can be connected to the machine body. During the operation of the cleaning device, the user can push the machine body to make the brush assembly 100 advance or retreat.

[0225] The cleaning device provided by the embodiment of the present application can flip the rolling brush cover plate 131 relative to the brush main body 110, so that the front squeegee 132 can be lifted or lowered. When the brush assembly 100 is pushed forward, the front squeegee 132 can be controlled to be lifted, so as to clean the water stains on the surface to be cleaned by the rolling brush 120 and the rear squeegee. When the brush assembly 100 is pulled backward, the front squeegee 132 can be controlled to be lowered, so as to clean the water stains on the surface to be cleaned by the rolling brush 120 and the front squeegee 132, thereby improving the cleaning efficiency and cleaning effect, and being beneficial to improve the user experience.

[0226] And, when the floor brush assembly 100 encounters an obstacle, the front scraping strip 132 can be tightly attached to the bottom of the obstacle through the overturning of the roller brush cover plate 131 by the collision of the obstacle, so as to reduce the sanitary dead angle of the edge of the bottom of the obstacle, improve the cleaning area and improve the cleaning effect.

[0227] In addition, when the floor brush assembly 100 encounters an obstacle, the elastic member 141 can buffer the collision impact of the obstacle on the roller brush cover plate 131, which is beneficial to reduce the damage of the roller brush cover plate 131 and improve the service life of the roller brush cover plate 131.

[0228] In some examples, the cleaning device can further include a clean water tank and a sewage tank. The clean water tank and the sewage tank can be arranged on the floor brush assembly 100 or on the machine body. Alternatively, one of the clean water tank and the sewage tank can be arranged on the floor brush assembly 100, and the other can be arranged on the machine body. The present application is not limited in this embodiment.

[0229] The present application also provides a cleaning system. The cleaning system can include a base or a base station. The cleaning device can be placed on the base or the base station.

[0230] In some examples, the base can be used to wash the roller brush 120 and dry the roller brush 120, so as to avoid the generation of odor or bacteria caused by the long time of the roller brush 120 in a wet state.

[0231] In some examples, the base station can have a charging function. When the cleaning device is placed on the base station, the cleaning device can be charged and automatically supplied with water. The base and the base station can be a split structure, or the base and the base station can be an integrated structure, which is not limited in the present application.
