Description

Technical Field

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

[0002] Cleaning equipment, such as floor scrubbers, is suitable for cleaning floors, carpets, and other surfaces, while simultaneously sucking up wastewater and removing it from the site. They offer advantages such as environmental friendliness, energy efficiency, and high efficiency. The roller brush is a key component of a floor scrubber, its primary function being to clean the surface through mechanical rotation and friction.

[0003] Roller brushes can be used to clean various surfaces, such as tiles, floors, and carpets. A scraper assembly is attached to the roller brush, which contacts the brush assembly to clean dirt from the roller brush and remove it from the surface through a vacuum duct. Roller brushes made of different materials can be used depending on the type of surface being cleaned.

[0004] In related art, when cleaning hard surfaces such as floors, the contact depth between the roller brush and the scraper assembly is relatively large, which can achieve a water squeezing action to reduce the moisture content of the flexible roller brush and achieve the purpose of quickly drying the hard surface to be cleaned. When cleaning soft surfaces such as carpets, the soft surface to be cleaned is soft in texture and has less support for the roller brush. Therefore, it is easy for the roller brush to sink too much into the soft surface to be cleaned, resulting in a larger contact area between the roller brush and the soft surface to be cleaned, thereby increasing the friction between the roller brush and the soft surface to be cleaned, and causing wear on the roller brush and the soft surface to be cleaned. Utility Model Content

[0005] The present application provides a floor brush assembly, a cleaning device and a cleaning system, which can solve the problem of easy wear of the roller brush and the soft surface to be cleaned when the roller brush cleans the soft surface to be cleaned.

[0006] In a first aspect, the present application provides a floor brush assembly, comprising:

[0007] Floor brush body;

[0008] A roller brush, the roller brush being detachably connected to the floor brush body and rotating to clean the surface to be cleaned;

[0009] An auxiliary wheel assembly, the auxiliary wheel assembly is provided on the floor brush body, and the auxiliary wheel assembly can be used to support the floor brush body;

[0010] A scraper bar assembly, the scraper bar assembly is arranged on the floor brush body, and the scraper bar assembly corresponds to the roller brush;

[0011] a first adjusting member, the first adjusting member being arranged on the floor brush body, the auxiliary wheel assembly and the scraping strip assembly being both transmission-connected to the first adjusting member;

[0012] The first adjusting member can drive the scraper assembly to move toward or away from the roller brush, and the movement of the first adjusting member can drive the auxiliary wheel assembly to move toward or away from the floor brush body.

[0013] The roller brush can be used to clean different types of surfaces to be cleaned. In related technologies, when cleaning hard surfaces to be cleaned, such as floors, the contact depth between the roller brush and the scraper assembly is relatively large, which can achieve a water squeezing action to reduce the water content of the flexible roller brush and achieve the purpose of quickly drying the floor. When cleaning soft surfaces to be cleaned, such as carpets, the soft surface to be cleaned is soft in texture and has less support for the roller brush. Therefore, it is easy for the roller brush to sink too much into the soft surface to be cleaned, resulting in a larger contact area between the roller brush and the soft surface to be cleaned, thereby increasing the friction between the roller brush and the soft surface to be cleaned, resulting in wear of the roller brush and the soft surface to be cleaned itself.

[0014] Therefore, based on the above technical problems, an embodiment of the present application provides a floor brush assembly, which can adjust the contact depth between the roller brush and the scraper assembly, and the roller brush and the surface to be cleaned through a first adjustment member when cleaning different types of surfaces to be cleaned, so as to reduce the wear of the roller brush and the surface to be cleaned itself while ensuring the cleaning effect of the surface to be cleaned.

[0015] Specifically, the first adjustment member can drive the scraper bar assembly toward or away from the roller brush. Therefore, when cleaning hard surfaces, the first adjustment member can drive the scraper bar assembly closer to the roller brush, allowing for a greater contact depth between the scraper bar assembly and the roller brush, thereby cleaning dirt from the roller brush. When cleaning soft surfaces, the first adjustment member can drive the scraper bar assembly away from the roller brush, allowing for a smaller contact depth between the scraper bar assembly and the roller brush. This reduces the possibility of friction between the scraper bar assembly and the harder roller brush, leading to wear on the roller brush and the surface to be cleaned, noise generation, and reduced impact on the motor, roller brush life, and battery life.

[0016] In addition, the first adjustment member of the embodiment of the present application can also be used to drive the auxiliary wheel assembly to move in a direction closer to or away from the floor brush body. When cleaning a hard surface to be cleaned, the auxiliary wheel assembly can be close to the floor brush body to reduce the distance between the floor brush body and the hard surface to be cleaned. At this time, there can be a greater contact pressure between the roller brush and the hard surface to be cleaned to improve the cleaning effect on the hard surface to be cleaned. When cleaning a soft surface to be cleaned, the auxiliary wheel assembly can be moved away from the floor brush body to raise the floor brush body. In other words, the auxiliary wheel assembly is moved away from the floor brush body to increase the distance between the floor brush body and the soft surface to be cleaned, so that when the cleaning device is running on the soft surface to be cleaned, the roller brush can be lifted and is not easily sunk into the fluff on the soft surface to be cleaned, which is beneficial to reduce the possibility of fluff being entangled in the roller brush, thereby increasing the rotation resistance of the roller brush, affecting the endurance, and even easily tearing the fluff, resulting in damage to the soft surface to be cleaned.

[0017] In addition, the embodiment of the present application can drive the scraper assembly and the auxiliary wheel assembly through the mechanical movement of the first adjusting member. In other words, the embodiment of the present application can be used to drive the scraper assembly and the auxiliary wheel assembly through a purely mechanical structural method instead of using RFID (radio frequency identification) technology. Therefore, the cleaning equipment no longer needs to drive the scraper assembly and the auxiliary wheel assembly through a driving source (such as a motor), which can reduce the power consumption of the cleaning equipment on the one hand, which is conducive to extending the battery life of the cleaning equipment and improving the user experience. On the other hand, it can reduce the cost of the cleaning equipment.

[0018] According to one embodiment of the present application, the first adjusting member can slide on the floor brush body along a first direction and has a first position and a second position;

[0019] When the first adjusting member is in the first position, the scraper bar assembly and the roller brush have a first contact depth, and the auxiliary wheel assembly is in an ascending position; when the first adjusting member is in the second position, the scraper bar assembly and the roller brush have a second contact depth or gap, and the auxiliary wheel assembly is in a descending position; wherein, the first contact depth is greater than the second contact depth.

[0020] When the floor brush assembly cleans a hard surface to be cleaned, the first adjusting member is located at the first position; when the floor brush assembly cleans a soft surface to be cleaned, the first adjusting member is located at the second position.

[0021] With this arrangement, the first adjustment member can be slid in a first direction to adjust the contact depth between the scraper assembly and the roller brush. When cleaning hard surfaces, the first adjustment member can be in the first position. Since the first adjustment member is connected to the scraper assembly, the first adjustment member can cause the scraper assembly and the roller brush to contact each other, achieving a first contact depth between the scraper assembly and the roller brush. In other words, the scraper assembly can penetrate deep into the bristles of the roller brush surface, so that during the roller brush's rotation, the scraper assembly and the roller brush come into contact, thereby scraping away dirt from the roller brush.

[0022] Furthermore, since the first adjustment member is connected to the auxiliary wheel assembly, when the first adjustment member is in the first position, the first adjustment assembly can place the auxiliary wheel assembly in an ascending position. It should be noted that the ascending position refers to the auxiliary wheel assembly moving a certain distance toward the floor brush body. Since the auxiliary wheel assembly is located on the surface to be cleaned, when the auxiliary wheel assembly is close to the floor brush body, the distance between the floor brush body and the surface to be cleaned is smaller, and the bristles of the roller brush can sink to the surface to be cleaned, so that the roller brush has a greater contact pressure on the surface to be cleaned, and the roller brush can fully contact the surface to be cleaned, thereby improving the cleaning effect.

[0023] When cleaning a soft surface to be cleaned, the first adjusting member can be moved from the first position to the second position. When the first adjusting member is moved to the second position, the first adjusting member can drive the scraper bar assembly to move away from the roller brush. At this time, the scraper bar assembly and the roller brush can have a second contact depth, or a gap can be provided between the scraper bar assembly and the roller brush so that the two do not contact each other. Therefore, during the rotation of the roller brush, the scraper bar assembly is less likely to cause a large frictional resistance to the movement of the roller brush.

[0024] Furthermore, since the first adjusting member is connected to the auxiliary wheel assembly, when the first adjusting member is in the second position, the first adjusting member can drive the auxiliary wheel assembly to a lowered position. It should be noted that the lowered position refers to the auxiliary wheel assembly moving a certain distance in the direction away from the floor brush body. Since the auxiliary wheel assembly is located on the surface to be cleaned, when the auxiliary wheel assembly moves in the direction away from the floor brush body, the floor brush body can be pushed a certain height in the direction away from the surface to be cleaned to raise the floor brush body and the roller brush. At this time, when the cleaning device moves on the soft surface to be cleaned, the distance that the roller brush is raised can compensate for the distance that the floor brush body is sunk into the soft surface to be cleaned, so as to reduce the possibility of the fluff on the soft surface to be cleaned being drawn into the roller brush during the rotation of the roller brush, thereby increasing the rotation resistance of the roller brush and damaging the soft surface to be cleaned.

[0025] According to one embodiment of the present application, the auxiliary wheel assembly is movably connected to the floor brush body, and the sliding of the first adjusting member can drive the auxiliary wheel assembly to rise or fall relative to the floor brush body, so that the auxiliary wheel assembly is in the raised position or the lowered position.

[0026] With this arrangement, the auxiliary wheel assembly is movably connected to the floor brush body, and can drive the auxiliary wheel assembly to move relative to the floor brush body during the sliding process of the first adjusting member. The auxiliary wheel assembly can be raised or lowered to drive the floor brush body to rise or fall.

[0027] According to one embodiment of the present application, the auxiliary wheel assembly includes a first rotating portion, and the auxiliary wheel assembly is rotatably connected to the floor brush body via the first rotating portion;

[0028] The auxiliary wheel assembly further includes a first adapter portion connected to the first adjusting member, and the first adapter portion can drive the auxiliary wheel assembly to flip forward or backward around the axis of the first rotating portion.

[0029] With this arrangement, since the first adapter is connected to the first adjusting member, the movement of the first adjusting member can drive the auxiliary wheel assembly to flip forward or reverse around the axis of the first rotating portion through the first adapter. Wherein, forward flipping can refer to clockwise rotation, and reverse flipping can refer to counterclockwise rotation. Since the auxiliary wheel assembly can be rotatably connected to the floor brush body through the first rotating portion, the auxiliary wheel assembly can rotate around the axis of the first rotating portion. Figure 4 and Figure 6 In the direction shown, when the auxiliary wheel assembly is flipped forward relative to the axis of the first rotating part, the end of the auxiliary wheel assembly that contacts the surface to be cleaned can be close to the floor brush body, the auxiliary wheel assembly is in the raised position, and the roller brush is used to clean hard surfaces. When the auxiliary wheel assembly is flipped backward relative to the axis of the first rotating part, the end of the auxiliary wheel assembly that contacts the surface to be cleaned can be away from the floor brush body, and the auxiliary wheel assembly can push against the surface to be cleaned, causing the floor brush body to rise, thereby raising the roller brush. At this time, the auxiliary wheel assembly is in the lowered position, and the roller brush is used to clean soft surfaces.

[0030] According to one embodiment of the present application, the auxiliary wheel assembly includes a roller and a flip frame, the roller is rotatably connected to the flip frame, and the roller protrudes downward from the bottom end surface of the flip frame; the first adapter portion is located at the upper end of the flip frame, and the first rotating portion is located between the roller and the first adapter portion.

[0031] With this arrangement, the flip frame can rotate around the axis of the first rotating part. Since the first rotating part is located between the roller and the first adapter part, the roller and the first adapter part can move synchronously around the axis of the first rotating part. Figure 4 and Figure 6In the direction shown, when the first adjusting member drives the first adapter to rotate clockwise, the flip frame can also flip forward around the axis of the first rotating portion. At this time, the roller moves toward the direction of the floor brush body to reduce the distance between the roller brush and the surface to be cleaned, thereby making it suitable for cleaning hard surfaces. When the first adjusting member drives the first adapter to rotate counterclockwise, the flip frame can also flip backward around the axis of the first rotating portion. At this time, the roller moves toward the direction of the floor brush body to increase the distance between the roller brush and the surface to be cleaned, thereby making it suitable for cleaning soft surfaces.

[0032] According to one embodiment of the present application, the first adjusting member is provided with a guide slide, at least a portion of the first adapter portion is located on the guide slide, and the first adapter portion moves relative to the guide slide.

[0033] With this arrangement, when the first adjusting member slides in the first direction, the guide slide can drive the first adapter portion to rotate about the axis of the first rotating portion via the guide slide. Because at least a portion of the first adapter portion can be located within the guide slide, and the guide slide is located on the first adjusting member, when the first adjusting member slides in the first direction, the guide slide can move relative to the first adapter portion, thereby driving the first adapter portion to rotate about the axis of the first rotating portion.

[0034] According to one embodiment of the present application, the guide slide is obliquely arranged on the first adjusting member, the extension direction of the guide slide has an angle with the sliding direction of the first adjusting member, and the extension direction of the guide slide has an angle with the forward direction of the floor brush assembly.

[0035] With this arrangement, since the first adjusting member slides in the first direction, in order to achieve the first adapter portion flipping about the axis of the first rotating portion, the guide slide can be tilted to provide a flipping force for the first adapter portion. During the sliding of the first adjusting member in the first direction, the first adapter portion can follow a flipping motion path about the axis of the first rotating portion under the guidance of the inner wall of the tilted guide slide.

[0036] According to one embodiment of the present application, the guide slide has a first end and a second end. Along the first direction, the first end is closer to the center of the floor brush body relative to the second end; along the forward direction of the floor brush assembly, the second end of the guide slide is closer to the front end of the floor brush assembly relative to the first end.

[0037] When the first adjusting member is located at the first position, the first adapter portion is located at the first end of the guide slide; when the first adjusting member is located at the second position, the first adapter portion is located at the second end of the guide slide.

[0038] In this way, since the second end of the guide slide is closer to the front end of the floor brush assembly than the first end, Figure 4 and Figure 6 In the direction shown, when the first adapter is located at the second end of the guide slide, the first adapter can drive the auxiliary wheel assembly to flip around the first rotating part in the opposite direction, and the roller brush can be used to clean the soft surface to be cleaned.

[0039] According to one embodiment of the present application, the first adjusting member is provided with a first through hole and a second through hole, the first through hole corresponds to the first end of the guide slide, and the second through hole corresponds to the second end of the guide slide.

[0040] In this arrangement, when the user operates the first adjustment member to switch the roller brush and clean different surfaces to be cleaned, the user can confirm the position of the first adapter through the first through hole and the second through hole, so that the user can easily confirm whether the current state of the floor brush assembly is used to clean the hard surface to be cleaned or the soft surface to be cleaned.

[0041] According to one embodiment of the present application, the scraper bar assembly can be rotatably connected to the floor brush body, and the sliding of the first adjusting member can drive the scraper bar assembly to flip forward or reverse, so that the scraper bar assembly and the roller brush have a first contact depth or a second contact depth or gap.

[0042] With this arrangement, the scraper bar assembly is rotatably connected to the floor brush body, and can be driven to move relative to the floor brush body during the sliding of the first adjusting member. The scraper bar assembly can be flipped forward or backward to move closer to or away from the roller brush.

[0043] According to one embodiment of the present application, the scraper bar assembly includes a second rotating portion, and the scraper bar assembly is rotatably connected to the floor brush body via the second rotating portion;

[0044] The scraper assembly further includes a second adapter portion connected to the first adjusting member, and the first adjusting member can drive the second adapter portion to rise or fall, so as to make the scraper assembly rotate forward or reverse around the axis of the second rotating portion.

[0045] In this arrangement, since the scraper assembly can be rotatably connected to the floor brush body through the second rotating part, the scraper assembly can rotate around the axis of the second rotating part. Since the second adapter is connected to the first adjusting member, the movement of the first adjusting member can drive the second adapter to rise or fall. Therefore, Figure 4 and Figure 6In the direction shown, when the first adjustment member drives the second adapter to rise, the scraper bar assembly can be reversed around the axis of the second rotating shaft, and the scraper bar assembly can be moved away from the floor brush body, and the roller brush can be used to clean soft surfaces. When the first adjustment member drives the second adapter to descend, the scraper bar assembly can be reversed around the axis of the second rotating portion, and the scraper bar assembly can be moved closer to the floor brush body, and the roller brush can be used to clean hard surfaces.

[0046] According to one embodiment of the present application, the first adjusting member is provided with a sliding groove for the second adapter part to slide, and at least part of the second adapter part is located in the sliding groove; the second adapter part is cooperatively connected with the sliding groove to make the second adapter part rise or fall.

[0047] With this arrangement, since a portion of the second adapter portion can slide within the chute, the chute can provide a guide for the second adapter portion. When the first adjusting member slides in the first direction, the second adapter portion and the chute move relative to each other in the first direction. The chute can also guide the second adapter portion in the second direction, thereby driving the second adapter portion to rise or fall.

[0048] According to one embodiment of the present application, along the second direction, the second adapter portion is provided with a first inclined surface facing the slide groove, the first adjusting member is provided with a second inclined surface corresponding to the first inclined surface, and the first inclined surface is slidably connected to the second inclined surface to make the second adapter portion rise or fall.

[0049] With such arrangement, since the second adapter part slides along the slide groove, when the first adjusting member slides along the first direction, when the first inclined surface on the second adapter part contacts the second inclined surface on the first adjusting member, the first inclined surface and the second inclined surface can slide in coordination, and the second inclined surface can push the second adapter part to slide along the direction of the second inclined surface to make the second adapter part rise, or the second inclined surface can gradually release the pushing force on the second adapter part to make the second adapter part fall.

[0050] According to one embodiment of the present application, the floor brush body is provided with a partition, and along the forward direction of the floor brush assembly, the partition is located on the side of the first adjusting member facing the roller, and the partition is provided with a lifting slide, and at least part of the second adapter portion can be passed through the lifting slide, and the second adapter portion corresponds to the slide groove.

[0051] With this arrangement, the partition can be used to secure other components within the floor brush assembly. The side of the partition facing away from the roller brush can form a mounting platform for securing the first adjustment member. Because the partition is provided with a lifting slideway through which the second adapter can pass, the second adapter can rise and fall along the lifting slideway as the first adjustment member slides in the first direction.

[0052] According to one embodiment of the present application, the scraper strip assembly further includes a connected scraper strip and a second adjusting member, the second adapter portion is located on a side of the second adjusting member facing away from the scraper strip, and the second rotating portion is located between the second adapter portion and the scraper strip.

[0053] In this arrangement, since the second rotating portion is located between the second adapter portion and the scraper strip, the second adapter portion and the scraper strip can rotate synchronously around the axis of the second rotating portion. Figure 4 and Figure 6 In the direction shown, when the second adapter portion rises, it reverses around the axis of the second rotating portion, driving the scraper bar to reversely reverse, allowing the scraper bar to move away from the roller brush, thereby reducing the depth of the scraper bar's penetration into the bristles of the roller brush. In other words, the reverse rotation of the scraper bar can adjust the first contact depth between the scraper bar and the roller brush to a second contact depth or gap, thereby switching to cleaning soft surfaces.

[0054] Similarly, when the second adapter portion descends, it can rotate forward about the axis of the second rotating portion, driving the scraper bar to also rotate forward, allowing the scraper bar to move closer to the roller brush, thereby increasing the depth of the scraper bar's penetration into the bristles of the roller brush. In other words, the forward rotation of the scraper bar can adjust the second contact depth or gap between the scraper bar and the roller brush to the first contact depth, thereby switching to cleaning hard surfaces.

[0055] According to one embodiment of the present application, the scraper bar assembly further includes a water divider, the water divider corresponds to the roller brush, the scraper bar is arranged on the water divider, and the second adjusting member is arranged on a side of the water divider facing away from the roller brush.

[0056] With this configuration, the roller brush extends in a first direction to increase the contact area between the roller brush and the surface to be cleaned. The scraper bar corresponds to the roller brush and is used to clean the roller brush. Therefore, the scraper bar can also extend in the first direction. Since the water divider also corresponds to the roller brush, the water divider can also extend in the first direction. The water divider can be used to connect the second adjustment member to the scraper bar. The second adjustment member can extend in the first direction to improve the stability of the scraper bar during its rotation.

[0057] According to one embodiment of the present application, the floor brush assembly further includes a reset member, which is connected to the first adjusting member and is used to drive the first adjusting member to reset from the second position to the first position.

[0058] With this arrangement, when it is necessary to switch back to cleaning the hard surface to be cleaned, the first adjusting member can be restored to the first position by the reset member. Since the reset member can be elastic, when it is necessary to reset the first adjusting member from the second position to the first position, the force applied to the first adjusting member toward the second position can be canceled. At this time, the reset member can automatically return the first adjusting member to the first position under the elastic force, without the need for manual reset.

[0059] According to one embodiment of the present application, the floor brush assembly includes a first fixing structure, which is provided on the floor brush body;

[0060] Along the sliding direction of the first adjusting member, the first adjusting member is provided with a second fixing structure corresponding to the first fixing structure, one end of the reset member is connected to the first fixing structure, and the other end of the reset member is connected to the second fixing structure.

[0061] With this arrangement, the first fixing structure can remain stationary relative to the floor brush body. The second fixing structure can move synchronously with the first adjusting member. Therefore, when the first adjusting member moves from the first position to the second position, the second fixing structure can approach the first fixing structure, causing the reset member between the two to undergo compressive deformation.

[0062] According to one embodiment of the present application, the floor brush body is provided with a mounting platform for fixing the first adjusting member, and the floor brush assembly further includes an air duct cover plate, part of which is connected to the mounting platform, and the first fixing structure is located on the air duct cover plate.

[0063] With this arrangement, the vacuum duct can be fixed to the mounting platform via the duct cover. By providing the first fixing structure on the duct cover, the first fixing structure can be located on the first adjusting member when the duct cover is fixedly connected to the mounting platform, which helps save assembly steps and improve assembly efficiency.

[0064] According to one embodiment of the present application, the roller brush includes a lateral mounting portion, and the connecting piece on the lateral mounting portion is detachably connected to the side wall of the floor brush body. The connecting piece faces the first adjusting piece, and the connecting piece contacts the first adjusting piece to push the first adjusting piece to move along the first direction.

[0065] In this way, the roller brush can be fixed to the side wall of the floor brush body through the lateral mounting portion, and the roller brush can be detachable from the floor brush body through the lateral mounting portion for switching the roller brush, so that a flexible roller brush can be used when cleaning hard surfaces to be cleaned, and a hard roller brush can be used when cleaning soft surfaces to be cleaned.

[0066] Because a connector is provided on the side of the lateral mounting portion facing the first connecting portion, when the roller brush is fixed to the floor brush body via the lateral mounting portion, the connector can be connected to the first adjusting member. Therefore, the driving force for the first adjusting member to slide along the first direction can be provided by the connector. The connectors on different roller brushes vary in size. Therefore, when switching between roller brushes, the first adjusting member can be driven to the first position or the second position via connectors of different sizes, thereby adapting the positions of the scraper assembly and the auxiliary wheel assembly to the corresponding roller brush, thereby cleaning surfaces of different materials.

[0067] According to one embodiment of the present application, the connecting piece is snapped onto the side wall of the floor brush body.

[0068] With this arrangement, the snap-on fixing method facilitates operation. The side wall of the floor brush body may be provided with a mounting opening through which the connecting member can be inserted. The connecting member may be provided with a snap-fitting portion. When the connecting member passes through the mounting opening, the snap-fitting portion snaps onto the side wall of the floor brush body, preventing the snap-fitting portion from being easily removed from the mounting opening, thereby achieving a fixed connection between the lateral mounting portion and the floor brush body, and further achieving a fixed connection between the roller brush and the floor brush body.

[0069] According to one embodiment of the present application, a side wall of the floor brush body is provided with a mounting opening, and the connecting member can be passed through the mounting opening to be connected to the first adjusting member;

[0070] Along the second direction, the connecting member is elastically connected to the side wall of the floor brush body so that the connecting member passes through the installation opening.

[0071] With this arrangement, when the connector passes through the mounting opening, the connector is elastically compressed by the inner wall of the mounting opening, allowing the connector to pass smoothly through the mounting opening. When the connector passes through the mounting opening, the connector releases its elastic potential energy, restoring the connector to a size larger than the mounting opening, making it less likely to fall out of the mounting opening, thereby improving the reliability of the connection between the lateral mounting portion and the floor brush body.

[0072] When replacing the roller brush, the user can press the connecting part along the second direction to cause the connecting part to be compressed and deformed. The size of the connecting part can be smaller than the size of the mounting port, and the connecting part can be smoothly removed from the mounting port, thereby realizing convenient disassembly of the lateral mounting part.

[0073] According to one embodiment of the present application, the roller brush is one of a first roller brush and a second roller brush, and along the first direction, the size of the connecting member of the second roller brush is larger than the size of the connecting member of the first roller brush.

[0074] In this arrangement, since the roller brush can be connected to the side wall of the floor brush body through the connecting piece of the lateral mounting portion, and the connecting piece can be used to drive the first adjusting piece to slide along the first direction, therefore, in the embodiment of the present application, the sizes of the connecting pieces on the first roller brush and the second roller brush can be set to be different, so as to drive the first adjusting piece to be located in the first position or the second position.

[0075] According to one embodiment of the present application, when the first roller brush is installed in place on the floor brush body, the first adjustment member is located at the first position; when the second roller brush is installed in place on the floor brush body, the first adjustment member is located at the second position.

[0076] With this arrangement, when the first roller brush is mounted on the floor brush body, the first adjusting member can be positioned in the first position under the action of the connecting member of the first roller brush. At this time, the scraping bar assembly can move toward the second roller brush, with a first contact depth between the scraping bar assembly and the first roller brush. At the same time, the auxiliary wheel assembly can be retracted toward the floor brush body to reduce the distance between the first roller brush and the hard surface to be cleaned. When the second roller brush is mounted on the floor brush body, the first adjusting member can be positioned in the second position under the action of the connecting member of the second roller brush. At this time, the scraping bar assembly can move toward the second roller brush, with a second contact depth or gap between the scraping bar assembly and the second roller brush. At the same time, the auxiliary wheel assembly can be extended toward the soft surface to be cleaned to increase the distance between the second roller brush and the soft surface to be cleaned.

[0077] Since it is necessary to switch roller brushes of different materials when cleaning different types of surfaces to be cleaned, the sizes of the connecting parts of roller brushes of different materials are set to be different. The position of the first adjustment part can be automatically adjusted after the roller brush is replaced, so that there is no need for additional user actions or operations, which is conducive to providing users with a worry-free and labor-saving experience, and can also avoid the phenomenon of abnormal cleaning caused by incorrect user operations.

[0078] In a second aspect, the present application provides a cleaning device, which includes a body and a floor brush assembly as described in any of the above embodiments.

[0079] The floor brush assembly is connected to the main body. The main body can be equipped with a sewage tank and a clean water tank. The detergent in the clean water tank can be sprayed onto the roller brush through a water separator. When the roller brush cleans the surface to be cleaned, the sewage squeezed off the roller brush by the scraper assembly can enter the sewage tank.

[0080] In a third aspect, the present application provides a cleaning system, which includes a base or a base station and the cleaning device described in any one of the above embodiments, and the cleaning device can be placed on the base or the base station.

[0081] With this configuration, the base can be used to clean and dry the roller brush to prevent it from being damp for extended periods, which can lead to the generation of odor or bacteria. The base station can also have a charging function. When the cleaning device is placed on the base station, the base station can be charged. Furthermore, the base station can also automatically load and discharge water, enabling automatic water replenishment and automatic sewage drainage.

[0083] The beneficial effect of the floor brush assembly provided by the present application is that, through the purely mechanical movement of the first adjustment member, the contact depth between the roller brush and the scraper assembly, and between the roller brush and the surface to be cleaned, can be adjusted, thereby reducing the possibility of wear and tear on the roller brush and the surface to be cleaned when cleaning different types of surfaces to be cleaned.

These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0112] The exemplary embodiments will be described in detail here, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation methods described in the following exemplary embodiments do not represent all implementation methods consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0113] The cleaning device provided in the embodiments of the present application may be a floor scrubber. A floor scrubber is a device used to clean floors. The operating principle of a floor scrubber is as follows: the high-speed operation of the motor drives the high-speed rotation of the roller brush. Simultaneously, the clean water tank operates, spraying clean water forward through a water channel onto the roller brush. The high-speed rotation of the roller brush then draws wastewater, etc., through a vacuum suction channel located behind the roller brush and backward through another water channel into the wastewater tank, thereby completing the cleaning process.

[0114] Roller brushes can be used to clean different types of floors, such as tiles, marble, wood floors, and carpets. Depending on the type of floor, the roller brush used has different materials and hardness. Therefore, you can switch to a roller brush that matches the floor material to achieve the best cleaning effect.

[0115] Specifically, for ease of description, the surfaces to be cleaned in the embodiments of the present application can be divided into hard surfaces to be cleaned and soft surfaces to be cleaned. Hard surfaces to be cleaned can refer to floors such as tiles, marble, wood floors, terrazzo, cement, and metal. Soft surfaces to be cleaned can refer to floors such as carpets and floor mats.

[0116] In related art, when cleaning hard surfaces such as floors, the contact depth between the roller brush and the scraper assembly is relatively large, which can achieve a water squeezing action to reduce the moisture content of the flexible roller brush and quickly dry the surface to be cleaned. When cleaning soft surfaces such as carpets, the soft surface to be cleaned is soft in texture and provides less support for the roller brush. Therefore, it is easy for the roller brush to sink too much into the soft surface to be cleaned, resulting in a larger contact area between the roller brush and the soft surface to be cleaned, thereby increasing the friction between the roller brush and the soft surface to be cleaned, and causing wear on the roller brush and the soft surface to be cleaned.

[0117] Specifically, when cleaning a soft surface to be cleaned, since the soft surface to be cleaned is soft and has fluff, when the cleaning device runs on the surface of the soft surface to be cleaned, the cleaning device will be recessed for a distance on the surface of the soft surface to be cleaned. At this time, the roller brush is easy to sink into the fluff of the soft surface to be cleaned, so that when the roller brush rotates, the fluff is easy to be rolled into the roller brush, resulting in increased friction resistance, and then increased rotation resistance of the roller brush, affecting endurance, and even easily tearing off the fluff, resulting in the possibility of damaging the soft surface to be cleaned.

[0118] To address the above technical issues, the applicant has improved the structure of existing floor brush assemblies. In one embodiment of the present application, the floor brush assembly includes a first adjustment member that can adjust the movement of the scraping bar assembly and the auxiliary wheel assembly. The first adjustment member can be used to drive the scraping bar assembly toward or away from the roller brush, and movement of the first adjustment member can drive the auxiliary wheel assembly toward or away from the floor brush body.

[0119] Therefore, when cleaning a hard surface, the first adjustment member can drive the scraper assembly to move closer to the roller brush, so that the scraper assembly can deeply contact the roller brush to clean the dirt on the roller brush. In addition, the auxiliary wheel assembly can be close to the floor brush body, so that the roller brush assembly can exert a certain force on the surface to be cleaned, thereby improving the cleaning effect of the surface.

[0120] When cleaning soft surfaces, the first adjustment member can drive the scraper assembly away from the roller brush to prevent significant friction between the scraper assembly and the roller brush, thereby reducing the possibility of abnormal noise or wear of the roller brush caused by hard friction between the scraper assembly and the roller brush. At this time, the auxiliary wheel assembly can extend away from the floor brush body to raise the floor brush body, thereby reducing the roller brush from sinking into the fluff on the soft surface to be cleaned, which would easily cause the fluff to be entangled in the roller brush, resulting in increased frictional resistance and, in turn, increased rotational resistance of the roller brush, affecting its endurance and even causing the fluff to be torn, resulting in damage to the soft surface to be cleaned.

[0121] The floor brush assembly 100, cleaning equipment, and cleaning system provided in the present application are described below with reference to the accompanying drawings and in combination with specific embodiments.

[0122] Figure 1 A schematic diagram of the three-dimensional structure of a floor brush assembly 100 provided in an embodiment of the present application; Figure 2 This is a schematic three-dimensional cross-sectional structure diagram of a floor brush assembly 100 provided in an embodiment of the present application.

[0123] See also Figure 1 and Figure 2 As shown, the floor brush assembly 100 of the embodiment of the present application includes a floor brush body 110 , a roller brush 120 , an auxiliary wheel assembly 130 , a scraper bar assembly 140 and a first adjustment member 150 .

[0124] The roller brush 120 is detachably connected to the floor brush body 110. The floor brush body 110 can move on the surface to be cleaned. The rotation of the roller brush 120 can clean the surface to be cleaned that the floor brush body 110 passes through. The roller brush 120 can be provided with a motor for driving the roller brush 120 to rotate.

[0125] The auxiliary wheel assembly 130 can be provided on the floor brush body 110. When the floor brush body 110 is located at the cleaning seat of the cleaning device, the auxiliary wheel assembly 130 can be used to support the floor brush body 110 to clean and dry the roller brush 120.

[0126] The scraper bar assembly 140 can be provided on the floor brush body 110, and the scraper bar assembly 140 can correspond to the roller brush 120. The scraper bar assembly 140 can be used to clean the dirt such as hair on the roller brush 120 by acting on the surface of the roller brush 120, and the scraper bar assembly 140 can squeeze out the liquid on the surface of the roller brush 120 to reduce the water content of the roller brush 120 and make the surface to be cleaned dry quickly.

[0127] The first adjusting member 150 can be disposed on the floor brush body 110. The auxiliary wheel assembly 130 and the scraping bar assembly 140 are both in transmission connection with the first adjusting member 150. The first adjusting member 150 can drive the scraping bar assembly 140 toward or away from the roller brush 120, and the movement of the first adjusting member 150 can drive the auxiliary wheel assembly 130 toward or away from the floor brush body 110.

[0128] In the embodiment of the present application, the first adjusting member 150 can drive the scraper bar assembly 140 toward or away from the roller brush 120. Therefore, when cleaning a hard surface to be cleaned, the first adjusting member 150 can drive the scraper bar assembly 140 toward the roller brush 120, thereby ensuring a greater contact depth between the scraper bar assembly 140 and the roller brush 120, thereby cleaning dirt on the roller brush 120. When cleaning a soft surface to be cleaned, since the roller brush 120 used to clean soft surfaces is made of a harder material, the first adjusting member 150 can drive the scraper bar assembly 140 away from the roller brush 120, thereby ensuring a smaller contact depth between the scraper bar assembly 140 and the roller brush 120. This reduces the possibility of friction between the scraper bar assembly 140 and the roller brush 120 causing wear and noise, and also reduces the impact on the lifespan and battery life of the motor and roller brush 120.

[0129] Furthermore, the first adjustment member 150 of the embodiment of the present application can also be used to drive the auxiliary wheel assembly 130 toward or away from the floor brush body 110. When cleaning hard surfaces, the auxiliary wheel assembly 130 can be moved closer to the floor brush body 110 to reduce the distance between the floor brush body 110 and the hard surface to be cleaned. At this time, the roller brush 120 can have a greater contact pressure with the hard surface to be cleaned, thereby improving the cleaning effect on the hard surface to be cleaned. When cleaning the soft surface to be cleaned, the auxiliary wheel assembly 130 can be moved away from the floor brush body 110 to raise the floor brush body 110. In other words, the auxiliary wheel assembly 130 is moved away from the floor brush body 110, which can increase the distance between the floor brush body 110 and the soft surface to be cleaned. Therefore, when the cleaning device is running on the soft surface to be cleaned, the roller brush 120 can be raised and is not easy to sink into the fluff of the soft surface to be cleaned. This is conducive to reducing the possibility of fluff being entangled in the roller brush 120, thereby increasing the rotational resistance of the roller brush 120, affecting the endurance, and even easily causing the fluff to be torn off, resulting in damage to the soft surface to be cleaned.

[0130] In summary, the embodiment of the present application can drive the scraper bar assembly 140 and the auxiliary wheel assembly 130 through the mechanical movement of the first adjusting member 150. In other words, the embodiment of the present application can be used to drive the scraper bar assembly 140 and the auxiliary wheel assembly 130 through a purely mechanical structural method instead of using RFID (radio frequency identification) technology. Therefore, the cleaning device no longer needs to drive the scraper bar assembly 140 and the auxiliary wheel assembly 130 through a driving source (such as a motor), which can reduce the power consumption of the cleaning device on the one hand, which is conducive to extending the battery life of the cleaning device and improving the user experience. On the other hand, it can reduce the cost of the cleaning device.

[0131] In some examples, when cleaning hard surfaces to be cleaned, a relatively soft roller brush, i.e., a flexible roller brush, can be used. The flexible roller brush has softer bristles to avoid scratching or damaging the hard surface to be cleaned. For example, the bristle material of the flexible roller brush may include nylon, polyester or other soft synthetic materials. When cleaning soft surfaces to be cleaned, a relatively hard roller brush can be used. The bristles of a hard roller brush are generally harder so that they can penetrate deep into the carpet fibers and improve the cleaning effect. The bristle material of a hard roller brush may include hard nylon or other wear-resistant materials.

[0132] Specifically, because the material of the hard roller brush is relatively hard, if the contact depth between the hard roller brush and the scraper assembly 140 remains the same as the contact depth between the flexible roller brush and the scraper assembly 140, the relative force between the scraper assembly 140 and the hard roller brush is relatively large. When the hard roller brush is in a rotating state, the large relative force between the scraper assembly 140 and the hard roller brush can easily hinder the rotation of the hard roller brush, and the scraper assembly 140 can easily scratch the surface of the hard roller brush. In addition, the scraper assembly 140 and the hard roller brush are prone to producing abnormal noises during the interaction, affecting the user experience. In addition, the scraper assembly 140 can also increase the rotational resistance of the hard roller brush, resulting in increased operating resistance of the motor, thereby affecting the battery life.

[0133] In some examples, when switching from a hard surface to be cleaned to a soft surface to be cleaned, the movement of the first adjustment member 150 can simultaneously drive the scraper assembly 140 and the auxiliary wheel assembly 130 to move, thereby improving the smoothness and convenience of the adjustment process.

[0134] In some examples, when cleaning a hard surface to be cleaned, the floor brush assembly 100 can spray cleaning liquid onto the roller brush 120 or the surface to be cleaned to wet the roller brush 120 and clean the dirt on the hard surface to be cleaned. When cleaning a soft surface to be cleaned, the floor brush assembly 100 can stop spraying cleaning liquid onto the roller brush 120 to prevent the soft surface from being wetted and not dried in time, which may lead to bacterial growth or odor.

[0135] Figure 3 A schematic diagram of a partial cross-sectional structure of a floor brush assembly 100 provided in an embodiment of the present application when the first adjustment member 150 is located in a first position; Figure 4 for Figure 3 A magnified schematic diagram of point A in the middle; Figure 5 This is a partial cross-sectional structural diagram of a floor brush assembly 100 provided in an embodiment of the present application when the first adjustment member 150 is located in the second position; Figure 6 for Figure 5 Enlarged schematic diagram of point B in the middle.

[0136] In some possible implementations, see Figures 3 to 6 As shown, the first adjustment member 150 of the embodiment of the present application can slide along the first direction X on the floor brush body 110 and has a first position and a second position. When the first adjustment member 150 is in the first position, the scraping bar assembly 140 and the roller brush 120 have a first contact depth m1, and the auxiliary wheel assembly 130 can be in the rising position. When the first adjustment member 150 is in the second position, the scraping bar assembly 140 and the roller brush 120 have a second contact depth or gap, and the auxiliary wheel assembly 130 can be in the descending position. The second contact depth and the gap can both be represented by m2. In the embodiment of the present application, the second contact depth is described as m2. The first contact depth m1 is greater than the second contact depth m2.

[0137] It should be noted that when cleaning hard surfaces, the scraper assembly 140 and the roller brush 120 have a first contact depth m1. For example, in this case, the roller brush 120 is a flexible roller brush. When cleaning soft surfaces, the scraper assembly 140 and the roller brush 120 have a second contact depth m2. For example, in this case, the roller brush 120 is a rigid roller brush. The first contact depth m1 is greater than the second contact depth m2.

[0138] In the embodiment of the present application, when the local brush assembly 100 cleans a hard surface to be cleaned, the first adjustment member 150 is located in the first position; when the local brush assembly 100 cleans a soft surface to be cleaned, the first adjustment member 150 is located in the second position.

[0139] The first adjusting member 150 can be slid along a first direction X to adjust the contact depth between the scraper bar assembly 140 and the roller brush 120. When cleaning hard surfaces, the first adjusting member 150 can be in the first position. Since the first adjusting member 150 is connected to the scraper bar assembly 140, the first adjusting member 150 can bring the scraper bar assembly 140 and the roller brush 120 into contact with each other, with a first contact depth m1 between the scraper bar assembly 140 and the roller brush 120. In other words, the scraper bar assembly 140 can penetrate deep into the bristles of the roller brush 120, so that during the rotation of the roller brush 120, the scraper bar assembly 140 and the roller brush 120 come into contact with each other, thereby scraping away dirt on the roller brush 120.

[0140] Furthermore, since the first adjusting member 150 is connected to the auxiliary wheel assembly 130, when the first adjusting member 150 is in the first position, the first adjusting assembly can place the auxiliary wheel assembly 130 in an ascending position. It should be noted that the ascending position refers to the auxiliary wheel assembly 130 moving a certain distance toward the floor brush body 110. Since the auxiliary wheel assembly 130 is located on the surface to be cleaned, when the auxiliary wheel assembly 130 is close to the floor brush body 110, the distance between the floor brush body 110 and the surface to be cleaned is small, and the bristles of the roller brush 120 can sink into the surface to be cleaned, so that the roller brush 120 has a greater contact pressure on the surface to be cleaned, and the roller brush 120 can fully contact the surface to be cleaned, thereby improving the cleaning effect.

[0141] When cleaning a soft surface to be cleaned, the first adjusting member 150 can be moved from the first position to the second position. When the first adjusting member 150 is moved to the second position, the first adjusting member 150 can drive the scraper assembly 140 to move away from the roller brush 120. At this time, a second contact depth m2 can be formed between the scraper assembly 140 and the roller brush 120, or a gap can be formed between the scraper assembly 140 and the roller brush 120 so that the two do not contact each other. Therefore, during the rotation of the roller brush 120, the scraper assembly 140 is unlikely to cause significant frictional resistance to the movement of the roller brush 120.

[0142] Furthermore, since the first adjusting member 150 is connected to the auxiliary wheel assembly 130, when the first adjusting member 150 is in the second position, the first adjusting member 150 can drive the auxiliary wheel assembly 130 to a lowered position. It should be noted that the lowered position refers to the auxiliary wheel assembly 130 moving a certain distance in the direction away from the floor brush body 110. Since the auxiliary wheel assembly 130 is located on the surface to be cleaned, when the auxiliary wheel assembly 130 moves in the direction away from the floor brush body 110, the floor brush body 110 can be pushed a certain height in the direction away from the surface to be cleaned, so as to raise the floor brush body 110 and the roller brush 120. At this time, when the cleaning device moves on the soft surface to be cleaned, the distance that the roller brush 120 is raised can compensate for the distance that the floor brush body 110 is sunk into the soft surface to be cleaned, so as to reduce the possibility that the fluff on the soft surface to be cleaned is drawn into the roller brush 120 during the rotation of the roller brush 120, thereby increasing the rotation resistance of the roller brush 120 and damaging the soft surface to be cleaned.

[0143] When the first adjustment member 150 is in the first position, the lowest point of the roller brush 120 can be lower than the lowest point of the auxiliary wheel assembly 130, thereby increasing the contact pressure between the roller brush 120 and the surface to be cleaned and improving the cleaning effect. Therefore, the greater the distance between the lowest point of the auxiliary wheel assembly 130 and the lowest point of the roller brush 120, the greater the contact pressure between the roller brush 120 and the surface to be cleaned. When the first adjustment member 150 is in the second position, the lowest point of the roller brush 120 can be slightly lower than the lowest point of the auxiliary wheel assembly 130, or flush with the lowest point of the auxiliary wheel assembly 130, or higher than the lowest point of the auxiliary wheel assembly 130. This is not specifically limited in the present embodiment and can be set according to the softness of the surface to be cleaned.

[0144] For example, see Figure 4 and Figure 6 As shown, when the first adjustment member 150 is in the first position, the distance between the lowest point of the auxiliary wheel assembly 130 and the lowest point of the roller brush 120 is n1. When the first adjustment member 150 is in the second position, the distance between the lowest point of the auxiliary wheel assembly 130 and the lowest point of the roller brush 120 is n2. n1 is greater than n2, so that when the first adjustment member 150 is in the first position, the roller brush 120 can fully contact the surface to be cleaned; and when the second adjustment member 143 is in the second position, the roller brush 120 can move upward to reduce the contact pressure with the surface to be cleaned.

[0145] It should be noted that the movement path of the scraper assembly 140 toward or away from the roller brush 120 may be flipping or horizontal translation, which is not limited in the present embodiment. The auxiliary wheel assembly 130 may rise or fall by flipping or translation along the second direction Y, which is not limited in the present embodiment. The second direction Y may be the vertical direction.

[0146] In some possible implementations, see Figure 4 and Figure 6 As shown, the auxiliary wheel assembly 130 of the embodiment of the present application can be movably connected to the floor brush body 110. The first adjustment member 150 slides to drive the auxiliary wheel assembly 130 to rise or fall relative to the floor brush body 110, so that the auxiliary wheel assembly 130 is in an ascending position or a descending position.

[0147] In the embodiment of the present application, the auxiliary wheel assembly 130 is movably connected to the floor brush body 110, and the auxiliary wheel assembly 130 can be driven to move relative to the floor brush body 110 during the sliding process of the first adjusting member 150. The raising or lowering of the auxiliary wheel assembly 130 can drive the floor brush body 110 to rise or fall.

[0148] In some possible implementations, see Figure 4 and Figure 6As shown, the auxiliary wheel assembly 130 of the embodiment of the present application may include a first rotating portion 131. The auxiliary wheel assembly 130 can be rotatably connected to the floor brush body 110 via the first rotating portion 131. The auxiliary wheel assembly 130 may also include a first adapter portion 1331 connected to the first adjustment member 150. The first adapter portion 1331 can drive the auxiliary wheel assembly 130 to flip forward or backward around the axis of the first rotating portion 131.

[0149] In the embodiment of the present application, since the first adapter portion 1331 is connected to the first adjusting member 150, the movement of the first adjusting member 150 can drive the auxiliary wheel assembly 130 to flip forward or reverse around the axis of the first rotating portion 131 through the first adapter portion 1331. Among them, forward flipping can refer to clockwise rotation, and reverse flipping can refer to counterclockwise rotation. Since the auxiliary wheel assembly 130 can be rotatably connected to the floor brush body 110 through the first rotating portion 131, the auxiliary wheel assembly 130 can rotate around the axis of the first rotating portion 131. Figure 4 and Figure 6 In the direction shown, when the auxiliary wheel assembly 130 is flipped forward relative to the axis of the first rotating portion 131, the end of the auxiliary wheel assembly 130 in contact with the surface to be cleaned can be close to the floor brush body 110, the auxiliary wheel assembly 130 is in the raised position, and the roller brush 120 is used to clean hard surfaces to be cleaned. When the auxiliary wheel assembly 130 is flipped backward relative to the axis of the first rotating portion 131, the end of the auxiliary wheel assembly 130 in contact with the surface to be cleaned can be away from the floor brush body 110, and the auxiliary wheel assembly 130 can push against the surface to be cleaned, causing the floor brush body 110 to rise, thereby raising the roller brush 120. At this time, the auxiliary wheel assembly 130 is in the lowered position, and the roller brush 120 is used to clean soft surfaces to be cleaned.

[0150] In some examples, there is at least one auxiliary wheel assembly 130. When there are multiple auxiliary wheel assemblies 130, the support stability of the floor brush body 110 can be improved. The number and position of the guide slides 151 match the auxiliary wheel assemblies 130. The number of auxiliary wheel assemblies 130 can be set based on the size of the floor brush body 110 along the first direction X, and is not limited in the present embodiment.

[0151] In some possible implementations, see Figure 4 and Figure 6 As shown, the auxiliary wheel assembly 130 of the present embodiment may include a roller 132 and a flip frame 133. The roller 132 is rotatably connected to the flip frame 133, and the roller 132 protrudes downward from the bottom end surface of the flip frame 133. The first adapter portion 1331 may be located at the upper end of the flip frame 133. The first rotating portion 131 is located between the roller 132 and the first adapter portion 1331.

[0152] In the embodiment of the present application, the flip frame 133 can rotate around the axis of the first rotating portion 131. Since the first rotating portion 131 is located between the roller 132 and the first adapter portion 1331, the roller 132 and the first adapter portion 1331 can move synchronously around the axis of the first rotating portion 131. Figure 4 and Figure 6 In the direction shown, when the first adjusting member 150 drives the first adapter 1331 to rotate clockwise, the flip frame 133 can also flip forward around the axis of the first rotating portion 131. At this time, the roller 132 moves toward the direction of the floor brush body 110 to reduce the distance between the roller brush 120 and the surface to be cleaned, thereby allowing it to be used to clean hard surfaces. When the first adjusting member 150 drives the first adapter 1331 to rotate counterclockwise, the flip frame 133 can also flip backward around the axis of the first rotating portion 131. At this time, the roller 132 moves toward the direction of the surface to be cleaned to increase the distance between the roller brush 120 and the surface to be cleaned, thereby allowing it to be used to clean soft surfaces.

[0153] In some examples, an angle between a line connecting the center of the roller 132 and the center of the first rotating portion 131 and a line connecting the centers of the first rotating portion 131 and the first adapter portion 1331 may be greater than or equal to a right angle.

[0154] In some examples, when the first adjusting member 150 is located at the first position, a line connecting the centers of the first rotating portion 131 and the first transition portion 1331 may be parallel to the second direction Y.

[0155] Figure 7 A schematic diagram of the three-dimensional structure of a first adjusting member 150 provided in an embodiment of the present application.

[0156] In some possible implementations, see Figures 4 to 7 As shown, the first adjusting member 150 of the embodiment of the present application may be provided with a guide slide 151. At least a portion of the first adapter portion 1331 may be located on the guide slide 151. The first adapter portion 1331 and the guide slide 151 move relative to each other.

[0157] In the embodiment of the present application, when the first adjusting member 150 slides along the first direction X, the first adapter portion 1331 can be driven to rotate about the axis of the first rotating portion 131 via the guide slide 151. Since at least a portion of the first adapter portion 1331 can be located within the guide slide 151, and the guide slide 151 is located on the first adjusting member 150, when the first adjusting member 150 slides along the first direction X, the guide slide 151 can move relative to the first adapter portion 1331 to drive the first adapter portion 1331 to rotate about the axis of the first rotating portion 131.

[0158] It should be noted that the movement direction of the first adapter portion 1331 is to flip forward or backward around the axis of the first rotating portion 131 , and the first adapter portion 1331 does not have a movement path that slides along the first direction X.

[0159] In some possible implementations, see Figure 7 As shown, the guide slide 151 of the embodiment of the present application can be tilted to the first adjustment member 150. The tilted setting means that the extension direction of the guide slide 151 and the sliding direction of the first adjustment member 150 can have an angle, and the extension direction of the guide slide 151 and the forward direction Z of the floor brush assembly 100 also have an angle.

[0160] Since the first adjusting member 150 moves in the first direction X, the first adapter portion 1331 can be tilted to provide a tilting force to the first adapter portion 1331. As the first adjusting member 150 slides in the first direction X, the first adapter portion 1331 can be guided by the inner wall of the tilted guide slide 151 to rotate about the axis of the first rotating portion 131.

[0161] In some examples, the guide slide 151 may have an inclined wall surface (not shown). When the floor brush assembly 100 moves on a horizontal surface to be cleaned, the inclined wall surface may form an angle with the second direction Y. Since the first adapter portion 1331 tilts during the flipping process, the inclined wall surface can match the inclined first adapter portion 1331 to increase the contact area between the two, thereby improving the smoothness and reliability of the movement.

[0162] In some examples, the guide slide 151 may have a first end 151a and a second end 151b. Along the first direction X, relative to the second end 151b, the first end 151a may be close to the center of the floor brush body 110. When the first adjustment member 150 is in the first position, the first adapter 1331 may be located at the first end 151a of the guide slide 151. Along the forward direction Z of the floor brush assembly 100, relative to the first end 151a, the second end 151b of the guide slide 151 may be close to the front end of the floor brush assembly 100. When the first adjustment member 150 is in the second position, the first adapter 1331 may be located at the second end 151b of the guide slide 151. Since the second end 151b of the guide slide 151 is closer to the front end of the floor brush assembly 100 relative to the first end 151a, reference Figure 4 and Figure 6In the direction shown, when the first adapter portion 1331 is located at the second end 151b of the guide slide 151, the first adapter portion 1331 can drive the auxiliary wheel assembly 130 to flip around the first rotating portion 131, and the roller brush 120 can be used to clean the soft surface to be cleaned.

[0163] In some examples, along the extension direction of the guide slide 151, at least one of the first end 151a and the second end 151b of the guide slide 151 may have an inclined abutment wall (not shown). Taking the second end 151b of the guide slide 151 as an example, when the first adapter 1331 is located at the second end 151b of the guide slide 151, the first adapter 1331 has an inclined angle with the second direction Y. Therefore, the inclined abutment wall can be used to fully contact the inclined first adapter 1331, so that the first adapter 1331 and the inclined abutment wall of the guide slide 151 fit together, thereby improving the uniformity of the mutual force between the first adapter 1331 and the guide slide 151 and improving the service life of the first adapter 1331.

[0164] In some examples, the guide slide 151 can be provided on the surface of the first adjustment member 150 facing the surface to be cleaned. The surface of the first adjustment member 150 facing away from the surface to be cleaned can be provided with a first through hole 150a and a second through hole 150b. The first through hole 150a can correspond to the first end 151a of the guide slide 151, and the second through hole 150b can correspond to the second end 151b of the guide slide 151. When the user operates the first adjustment member 150 to switch the roller brush 120 and clean different surfaces to be cleaned, the user can confirm the position of the first adapter 1331 through the first through hole 150a and the second through hole 150b, so that the user can easily confirm whether the current state of the floor brush assembly 100 is for cleaning the hard surface to be cleaned or the soft surface to be cleaned.

[0165] In some examples, at least one of the first through hole 150a and the second through hole 150b may be a waisted hole, which is not limited in the embodiment of the present application.

[0166] Figure 8 A schematic diagram of a partial three-dimensional structure of a floor brush assembly 100 provided in an embodiment of the present application; Figure 9 This is a schematic diagram of the partial decomposition structure of a floor brush assembly 100 provided in an embodiment of the present application.

[0167] In some possible implementations, see Figure 4 、 Figure 6 、 Figure 8 and Figure 9As shown, the scraper bar assembly 140 of the embodiment of the present application is rotatably connected to the floor brush body 110. The first adjustment member 150 slides to drive the scraper bar assembly 140 to flip forward or reverse, so that the scraper bar assembly 140 and the roller brush 120 have a first contact depth m1 or a second contact depth m2 or a gap.

[0168] In the embodiment of the present application, the scraper bar assembly 140 is rotatably connected to the floor brush body 110, and the scraper bar assembly 140 can be driven to move relative to the floor brush body 110 during the sliding process of the first adjustment member 150. The scraper bar assembly 140 can be flipped forward or backward to move closer to or away from the roller brush 120.

[0169] Specifically, see Figure 4 and Figure 6 In the direction shown, the scraper bar assembly 140 can be turned forward to be close to the roller brush 120, so that the scraper bar assembly 140 and the roller brush 120 have a first contact depth m1. The scraper bar assembly 140 can be turned backward to be away from the roller brush 120, so that the scraper bar assembly 140 and the roller brush 120 have a second contact depth m2 or gap.

[0170] In some embodiments, the scraper bar assembly 140 of the present invention may include a second rotating portion 141. The scraper bar assembly 140 may be rotatably connected to the floor brush body 110 via the second rotating portion 141. The scraper bar assembly 140 may also include a second adapter portion 1431 connected to the first adjustment member 150. The first adjustment member 150 may drive the second adapter portion 1431 to rise or fall, thereby causing the scraper bar assembly 140 to rotate forward or reverse around the axis of the second rotating portion 141.

[0171] In the embodiment of the present application, since the scraper assembly 140 can be rotatably connected to the floor brush body 110 through the second rotating portion 141, the scraper assembly 140 can rotate around the axis of the second rotating portion 141. Since the second adapter portion 1431 is connected to the first adjusting member 150, the movement of the first adjusting member 150 can drive the second adapter portion 1431 to rise or fall. Figure 4 and Figure 6 In the direction shown, when the first adjusting member 150 drives the second adapter 1431 upward, the scraper bar assembly 140 can be reversed around the axis of the second rotation shaft, and the scraper bar assembly 140 can be moved away from the floor brush body 110, and the roller brush 120 can be used to clean soft surfaces to be cleaned. When the first adjusting member 150 drives the second adapter 1431 downward, the scraper bar assembly 140 can be reversed around the axis of the second rotation portion 141, and the scraper bar assembly 140 can be moved closer to the floor brush body 110, and the roller brush 120 can be used to clean hard surfaces to be cleaned.

[0172] In some examples, the second rotating portion 141 can be fixed to the side wall 115 of the floor brush body via an adapter (not shown). The adapter can slide along the second direction Y into the side wall 115 of the floor brush body.

[0173] In some possible implementations, see Figure 8 and Figure 9 As shown, the first adjusting member 150 of the embodiment of the present application is provided with a slide groove 152 for sliding the second adapter portion 1431. At least a portion of the second adapter portion 1431 can be located in the slide groove 152. The second adapter portion 1431 is coupled with the slide groove 152 to allow the second adapter portion 1431 to rise or fall.

[0174] In the embodiment of the present application, since a portion of the second adapter portion 1431 can slide within the slide groove 152, the slide groove 152 can provide a guide for the second adapter portion 1431. When the first adjustment member 150 slides along the first direction X, the second adapter portion 1431 and the slide groove 152 can move relative to each other along the first direction X. The slide groove 152 can also guide the second adapter portion 1431 in the second direction Y, thereby driving the second adapter portion 1431 to rise or fall.

[0175] It should be noted that the movement direction of the first adjusting member 150 is along the first direction X. Since the second adapter portion 1431 can rotate around the axis of the second rotating portion 141, the second adapter portion 1431 does not necessarily move along the second direction Y when it is raised or lowered. The second adapter portion 1431 flips around the second rotating portion 141 during the raising or lowering process.

[0176] Figure 10 A schematic diagram of the three-dimensional structure of a scraper strip assembly 140 provided in an embodiment of the present application.

[0177] In some possible implementations, see Figures 8 to 10 As shown, along the second direction Y, the second adapter portion 1431 has a first inclined surface 140a facing the slide groove 152. The first adjustment member 150 has a second inclined surface 153 corresponding to the first inclined surface 140a. The first inclined surface 140a and the second inclined surface 153 are slidably connected to each other to allow the second adapter portion 1431 to rise or fall.

[0178] In the embodiment of the present application, since the second adapter portion 1431 slides along the slide groove 152, during the sliding process of the first adjusting member 150 along the first direction X, when the first inclined surface 140a on the second adapter portion 1431 contacts the second inclined surface 153 on the first adjusting member 150, the first inclined surface 140a and the second inclined surface 153 can cooperate to slide, and the second inclined surface 153 can push the second adapter portion 1431 to slide along the direction of the second inclined surface 153 to make the second adapter portion 1431 rise, or the second inclined surface 153 can gradually release the pushing force on the second adapter portion 1431 to make the second adapter portion 1431 descend.

[0179] In some examples, when the first adjusting member 150 is in the first position, the second adapter portion 1431 is located in the slide groove 152, and a gap may exist between the first inclined surface 140a and the second inclined surface 153. In other words, the first inclined surface 140a and the second inclined surface 153 may not be in contact with each other, and the second inclined surface 153 is unlikely to exert an upward pushing force on the first inclined surface 140a. At this time, the second adapter portion 1431 is in a downward position. Since the scraper assembly 140 can rotate around the axis of the second rotating portion 141, Figure 3 In the direction shown, when the second adapter portion 1431 is in the descending state, the scraper bar assembly 140 is flipped forward, and there is a larger first contact depth m1 between the scraper bar assembly 140 and the roller brush 120 for cleaning the hard surface to be cleaned.

[0180] When the first adjusting member 150 switches from the first position to the second position, the first adjusting member 150 slides along the first direction X so that the first inclined surface 140a and the second inclined surface 153 contact each other. Under the mutual guidance of the first inclined surface 140a and the second inclined surface 153, the second inclined surface 153 can exert an upward pushing force on the first inclined surface 140a, so that the second adapter 1431 is in an upward state. Since the scraper assembly 140 can rotate around the axis of the second rotating portion 141, Figure 3 In the direction shown, when the second adapter portion 1431 is in the raised state, the scraper assembly 140 flips over, and there is a smaller second contact depth m2 or a gap between the scraper assembly 140 and the roller brush 120 for cleaning the soft surface to be cleaned.

[0181] Figure 11 This is a schematic diagram of the main cross-sectional structure of a floor brush assembly 100 provided in an embodiment of the present application.

[0182] In some possible implementations, see Figure 1 、 Figure 2 and Figure 11As shown, the floor brush body 110 may include a partition 111. Along the forward direction Z of the floor brush assembly 100, the partition 111 may be located on the side of the first adjustment member 150 facing the roller 132. A lifting slide 111a may be provided on the partition 111. At least a portion of the second adapter portion 1431 may be inserted into the lifting slide 111a, so that the second adapter portion 1431 corresponds to the slide groove 152.

[0183] In this embodiment of the present application, the partition 111 can be used to secure other components within the floor brush assembly 100. The side of the partition 111 facing away from the roller brush 120 can form a mounting platform 113 for securing the first adjustment member 150. Because the partition 111 is provided with a lifting slide 111a through which the second adapter 1431 passes, the second adapter 1431 can be raised and lowered along the lifting slide 111a as the first adjustment member 150 slides in the first direction X.

[0184] In some examples, the number of second adapter portions 1431 can be at least one. The number of second adapter portions 1431 can match the number of chutes 152 and the number of lifting slides 111a. The number of second adapter portions 1431 can be set based on the size of the floor brush body 110 along the first direction X and is not limited in the present embodiment.

[0185] In some possible implementations, see Figure 10 As shown, the scraper bar assembly 140 of the embodiment of the present application may further include a connected scraper bar 142 and a second adjusting member 143. The second adapter portion 1431 is located on the side of the second adjusting member 143 facing away from the scraper bar 142. The second rotating portion 141 may be located between the second adapter portion 1431 and the scraper bar 142.

[0186] In the embodiment of the present application, the scraper bar 142 can be used to clean dirt and water from the roller brush 120. The scraper bar 142 can penetrate deep into the bristles of the roller brush 120 to clean the roller brush 120. Therefore, the first contact depth m1, the second contact depth m2, and the gap in the embodiment of the present application can refer to the contact depth or gap between the scraper bar 142 and the roller brush 120.

[0187] Since the second rotating portion 141 is located between the second adapter portion 1431 and the scraper strip 142, the second adapter portion 1431 and the scraper strip 142 can rotate synchronously around the axis of the second rotating portion 141. Figure 4 and Figure 6In the direction shown, when the second adapter portion 1431 rises, it reverses around the axis of the second rotating portion 141, driving the scraper bar 142 to reverse as well. The scraper bar 142 can move away from the roller brush 120, thereby reducing the depth of the scraper bar 142 penetrating into the bristles of the roller brush 120. In other words, the reverse rotation of the scraper bar 142 can adjust the first contact depth m1 between the scraper bar 142 and the roller brush 120 to the second contact depth m2 or gap, thereby switching to cleaning the soft surface to be cleaned.

[0188] Similarly, when the second adapter portion 1431 descends, it can rotate forwardly around the axis of the second rotating portion 141, driving the scraper bar 142 to rotate forwardly as well. The scraper bar 142 can move toward the roller brush 120, thereby increasing the depth of the scraper bar 142 inserted into the bristles of the roller brush 120. In other words, the forward rotation of the scraper bar 142 can adjust the second contact depth m2 or gap between the scraper bar 142 and the roller brush 120 to the first contact depth m1, thereby switching to cleaning hard surfaces.

[0189] In some possible implementations, see Figure 9 and Figure 10 As shown, the scraper bar assembly 140 of the embodiment of the present application may further include a water separator 144. The water separator 144 may correspond to the roller brush 120. The scraper bar 142 may be disposed on the water separator 144, and the second adjustment member 143 may be disposed on a side of the water separator 144 facing away from the roller brush 120.

[0190] In the embodiment of the present application, the roller brush 120 extends along the first direction X to increase the contact area between the roller brush 120 and the surface to be cleaned. The scraper bar 142 corresponds to the roller brush 120 and is used to clean the roller brush 120. Therefore, the scraper bar 142 can also extend along the first direction X. Since the water divider 144 also corresponds to the roller brush 120, the water divider 144 can also extend along the first direction X. The water divider 144 can be used to connect the second adjustment member 143 and the scraper bar 142. The second adjustment member 143 can extend along the first direction X to improve the stability of the scraper bar 142 during the flipping process.

[0191] In some examples, when there are two second adapter portions 1431, the second adapter portions 1431 can be located at both ends of the second adjusting member 143 along the first direction X. When cleaning hard surfaces to be cleaned, the water separator 144 can be used to spray cleaning liquid onto the roller brush 120 to soak the roller brush 120. When the roller brush 120 is wet, the scraper bar 142 can squeeze out the water in the roller brush 120 to quickly dry the surface to be cleaned. When switching to cleaning soft surfaces to be cleaned, the water separator 144 can stop spraying cleaning liquid to prevent the soft surface from being wetted and not dried in time, which may lead to bacterial growth or odor.

[0192] Figure 12 This is a schematic top view of the structure of a floor brush assembly 100 provided in an embodiment of the present application when the first adjustment member 150 is in the first position; at this time, the roller brush 120 is the first roller brush 120a; Figure 13 for Figure 12 Enlarged schematic diagram of point C in the middle; Figure 14 This is a schematic top view of the structure of a floor brush assembly 100 provided in an embodiment of the present application when the first adjustment member 150 is in the second position; at this time, the roller brush 120 is the second roller brush 120b; Figure 15 for Figure 14 Enlarged schematic diagram of point D in the middle.

[0193] In some possible implementations, see Figures 12 to 15 As shown, the floor brush assembly 100 of the embodiment of the present application may further include a reset member 160. The reset member 160 may be connected to the first adjustment member 150. The reset member 160 may be used to drive the first adjustment member 150 to reset from the second position to the first position.

[0194] In the embodiment of the present application, the first adjusting member 150 can slide along the first direction X to move from the first position to the second position. When the first adjusting member 150 is in the second position, the scraping bar 142 can move away from the roller brush 120 to have a second contact depth m2 or gap with the roller brush 120, and the auxiliary wheel assembly 130 can extend toward the surface to be cleaned to increase the distance between the floor brush body 110 and the surface to be cleaned, thereby enabling cleaning of soft surfaces to be cleaned. When it is necessary to switch back to cleaning hard surfaces to be cleaned, the first adjusting member 150 can be restored to the first position by the reset member 160.

[0195] The reset member 160 may be elastic. Therefore, when the first adjusting member 150 needs to be reset from the second position to the first position, the force applied to the first adjusting member 150 toward the second position can be canceled. At this time, the reset member 160 can automatically return the first adjusting member 150 to the first position under the elastic force, without the need for manual reset.

[0196] Specifically, during the movement of the first adjusting member 150 from the first position to the second position, the first adjusting member 150 can cause the reset member 160 to produce compression deformation. When the first adjusting member 150 moves to the second position, the reset member 160 can remain in a compressed state. During the process of the first adjusting member 150 resetting to the first position, the first adjusting member 150 is no longer subjected to the force moving in the direction of the second position, and the reset member 160 can release elastic potential energy to drive the first adjusting member 150 to move in the opposite direction, so that the reset member 160 can drive the first adjusting member 150 to return to the first position. At this time, the scraper 142 can move in the direction close to the roller brush 120 to have a first contact depth m1 with the roller brush 120, and the auxiliary wheel assembly 130 can be retracted in the direction of the floor brush body 110 to reduce the distance between the floor brush body 110 and the surface to be cleaned, so that the hard surface to be cleaned can be cleaned.

[0197] In some examples, when the first adjusting member 150 is in the first position, the reset member 160 may also have a smaller compression deformation. Therefore, there is a relative force between the reset member 160 and the first adjusting member 150, and the reset member 160 can maintain the movement trend of pushing the first adjusting member 150 so that the first adapter can be maintained at the first end 151a of the guide slide 151.

[0198] In some possible implementations, see Figure 13 and Figure 15 As shown, the floor brush assembly 100 may include a first fixing structure 112. The first fixing structure 112 may be provided on the floor brush body 110. Along the sliding direction of the first adjusting member 150, the first adjusting member 150 may be provided with a second fixing structure 154 corresponding to the first fixing structure 112. One end of the reset member 160 may be connected to the first fixing structure 112, and the other end of the reset member 160 may be connected to the second fixing structure 154.

[0199] In the embodiment of the present application, the first fixing structure 112 can remain stationary relative to the floor brush body 110. The second fixing structure 154 can move synchronously with the first adjusting member 150. Therefore, when the first adjusting member 150 moves from the first position to the second position, the second fixing structure 154 can approach the first fixing structure 112, so that the restoring member 160 between the two generates compressive deformation.

[0200] In some examples, the reset member 160 may be a part with elastic properties such as a spring or an elastic rubber member.

[0201] In some examples, the end surfaces of the first fixing member and the second fixing member facing each other may be respectively provided with guide posts. The two ends of the reset member 160 may be respectively sleeved on the two guide posts.

[0202] In some possible implementations, see Figure 13 and Figure 15 As shown, the floor brush body 110 is provided with a mounting platform 113 for fixing the first adjustment member 150. The floor brush assembly 100 further includes an air duct cover 114, a portion of which can be connected to the mounting platform 113, and the first fixing structure 112 can be located on the air duct cover 114.

[0203] In the embodiment of the present application, the vacuum duct can be fixed to the mounting platform 113 via the duct cover 114. By providing the first fixing structure 112 on the duct cover 114, the first fixing structure 112 can be located on the first adjustment member 150 when the duct cover 114 is fixedly connected to the mounting platform 113, which helps to save assembly steps and improve assembly efficiency.

[0204] Figure 16 This is a schematic diagram of the partial decomposition structure of the roller brush 120 and the floor brush body 110 provided in an embodiment of the present application.

[0205] In some possible implementations, see Figures 12 to 16 As shown, the roller brush 120 of the embodiment of the present application can include a lateral mounting portion 121. A connector 122 on the lateral mounting portion 121 is detachably connected to the side wall 115 of the floor brush body. The connector 122 can face the first adjustment member 150. The connector 122 contacts the first adjustment member 150 to push the first adjustment member 150 to move in the first direction X.

[0206] In an embodiment of the present application, the roller brush 120 can be fixed to the side wall 115 of the floor brush body through the lateral mounting portion 121, and the roller brush 120 can be detachable from the floor brush body 110 through the lateral mounting portion 121 for switching the roller brush 120, so that a flexible roller brush can be used when cleaning hard surfaces to be cleaned, and a hard roller brush can be used when cleaning soft surfaces to be cleaned.

[0207] Since a connecting member 122 is provided on the side of the lateral mounting portion 121 facing the first connecting portion, when the roller brush 120 is fixed to the floor brush body 110 via the lateral mounting portion 121, the connecting member 122 can be connected to the first adjusting member 150. Therefore, the driving force for the first adjusting member 150 to slide along the first direction X can be provided by the connecting member 122. The sizes of the connecting members 122 on different roller brushes 120 are different. Therefore, when switching between different roller brushes 120, the first adjusting member 150 can be driven to the first position or the second position by connecting members 122 of different sizes, so that the positions of the scraper assembly 140 and the auxiliary wheel assembly 130 can be adapted to the corresponding roller brush 120, thereby cleaning surfaces to be cleaned made of different materials.

[0208] In some examples, the end surface of the first adjusting member 150 that connects to the connecting member 122 can be a curved concave surface 150c. The connecting member 122 can have a curved convex surface 122a that matches the curved concave surface 150c. The connecting member 122 can cooperate with the curved convex surface 122a and the curved concave surface 150c to push the first adjusting member 150 to move along the first direction X.

[0209] In some possible implementations, see Figure 16 As shown, the connecting member 122 can be snapped onto the side wall 115 of the floor brush body.

[0210] In the embodiment of the present application, the snap-fit ​​fixing method can facilitate operation. The side wall 115 of the floor brush body can be provided with a mounting opening 115a for the connecting member 122 to pass through. The connecting member 122 can be provided with a snap-fit ​​portion 122b. When the connecting member 122 passes through the mounting opening 115a, the snap-fit ​​portion 122b can be snap-fitted to the side wall 115 of the floor brush body, so that the snap-fit ​​portion 122b is not easily detached from the mounting opening 115a, thereby achieving a fixed connection between the lateral mounting portion 121 and the floor brush body 110, and further achieving a fixed connection between the roller brush 120 and the floor brush body 110.

[0212] In some possible implementations, see Figure 16 and Figure 17 As shown, the connecting member 122 can be passed through the installation opening 115a to connect with the first adjusting member 150. Along the second direction Y, the connecting member 122 can be elastically connected to the side wall 115 of the floor brush body so that the connecting member 122 can pass through the installation opening 115a.

[0213] In the embodiment of the present application, when the connecting member 122 passes through the mounting opening 115a, the connecting member 122 is elastically compressed by the inner wall of the mounting opening 115a, so that the connecting member 122 can smoothly pass through the mounting opening 115a. When the connecting member 122 passes through the mounting opening 115a, the connecting member 122 can release its elastic potential energy to restore the connecting member 122 to a size larger than the mounting opening 115a. The connecting member 122 is unlikely to fall out of the mounting opening 115a, which helps to improve the connection reliability between the lateral mounting portion 121 and the floor brush body 110.

[0214] When replacing the roller brush 120, the user can press the connecting member 122 along the second direction Y to cause the connecting member 122 to produce compression deformation. The size of the connecting member 122 can be smaller than the size of the mounting port 115a, and the connecting member 122 can be smoothly removed from the mounting port 115a, thereby realizing convenient disassembly of the lateral mounting portion 121.

[0215] In some possible implementations, see Figures 12 to 15 As shown, the roller brush 120 of the embodiment of the present application may be one of a first roller brush 120a and a second roller brush 120b. Along the first direction X, the size of the connecting member 122 of the second roller brush 120b may be larger than that of the connecting member 122 of the first roller brush 120a.

[0216] Since the roller brush 120 can be clamped to the side wall 115 of the floor brush body through the connecting piece 122 of the lateral mounting portion 121, and the connecting piece 122 can be used to drive the first adjusting piece 150 to slide along the first direction X, therefore, in the embodiment of the present application, the sizes of the connecting pieces 122 on the first roller brush 120a and the second roller brush 120b can be set to be different, so as to drive the first adjusting piece 150 to be located in the first position or the second position.

[0217] The first roller brush 120a can be a flexible roller brush for cleaning hard surfaces. The second roller brush 120b can be a rigid roller brush for cleaning soft surfaces. The connector 122 on the second roller brush 120b is larger than the connector 122 on the first roller brush 120a. Therefore, when cleaning different surfaces, by installing different roller brushes 120, the contact depth between the scraper assembly 140 and the roller brush 120 can be automatically adjusted, and the contact distance between the roller brush 120 and the surface can also be automatically adjusted.

[0218] When cleaning hard surfaces to be cleaned, a first roller brush 120a made of a flexible material can be used. Since the size of the connecting member 122 of the first roller brush 120a along the first direction X is smaller than the size of the connecting member 122 of the second roller brush 120b, when the first roller brush 120a is fixed to the floor brush body 110, the connecting member 122 of the first roller brush 120a can drive the first adjusting member 150 to move to the first position. At this time, the scraping bar assembly 140 can move toward the first roller brush 120a, and a first contact depth m1 is formed between the scraping bar assembly 140 and the first roller brush 120a. At the same time, the auxiliary wheel assembly 130 can be retracted toward the floor brush body 110 to reduce the distance between the first roller brush 120a and the hard surface to be cleaned.

[0219] When cleaning soft surfaces to be cleaned, a second roller brush 120b made of a hard material can be used. Since the size of the connecting member 122 of the second roller brush 120b along the first direction X is larger than the size of the connecting member 122 of the first roller brush 120a, when the second roller brush 120b is fixed to the floor brush body 110, the connecting member 122 of the second roller brush 120b can drive the first adjusting member 150 to move to the second position. At this time, the scraping bar assembly 140 can move away from the second roller brush 120b, and a second contact depth m2 or gap is formed between the scraping bar assembly 140 and the second roller brush 120b. At the same time, the auxiliary wheel assembly 130 can extend toward the soft surface to be cleaned to increase the distance between the second roller brush 120b and the soft surface to be cleaned.

[0220] In some embodiments, when the first roller brush 120a is installed in place on the floor brush body 110, the first adjustment member 150 is located in the first position. When the second roller brush 120b is installed in place on the floor brush body 110, the first adjustment member 150 is located in the second position.

[0221] In an embodiment of the present application, when the first roller brush 120a is installed on the floor brush body 110, under the action of the connecting member 122 of the first roller brush 120a, the first adjusting member 150 can be located in the first position. At this time, the scraping bar assembly 140 can move toward the direction close to the second roller brush 120b, and there is a first contact depth m1 between the scraping bar assembly 140 and the first roller brush 120a. At the same time, the auxiliary wheel assembly 130 can be retracted toward the floor brush body 110 to reduce the distance between the first roller brush 120a and the hard surface to be cleaned. When the second roller brush 120b is installed on the floor brush body 110, under the action of the connecting member 122 of the second roller brush 120b, the first adjusting member 150 can be located in the second position. At this time, the scraping bar assembly 140 can move in the direction away from the second roller brush 120b, and there is a second contact depth m2 or gap between the scraping bar assembly 140 and the second roller brush 120b. At the same time, the auxiliary wheel assembly 130 can extend toward the direction of the soft surface to be cleaned to increase the distance between the second roller brush 120b and the soft surface to be cleaned.

[0222] Since it is necessary to switch roller brushes 120 of different materials when cleaning different types of surfaces to be cleaned, the sizes of the connecting parts 122 of roller brushes 120 of different materials are set to be different. The position of the first adjustment part 150 can be automatically adjusted after replacing the roller brush 120, thereby eliminating the need for additional user actions or operations, which is conducive to providing users with a worry-free and labor-saving experience, and can also avoid the phenomenon of abnormal cleaning caused by incorrect user operations.

[0223] An embodiment of the present application further provides a cleaning device, which may include a body and the floor brush assembly 100 in any of the above embodiments.

[0224] The floor brush assembly 100 is connected to the body. The body can be provided with a sewage tank and a clean water tank. The detergent in the clean water tank can be sprayed onto the roller brush 120 through the water separator 144. When the roller brush 120 cleans the surface to be cleaned, the sewage on the roller brush 120 squeezed out by the scraper assembly 140 can enter the sewage tank.

[0225] The embodiment of the present application further provides a cleaning system, which may include a base or a base station. A cleaning device may be placed on the base or the base station.

[0226] In some examples, the base can be used to clean the roller brush 120 and dry the roller brush 120 to prevent the roller brush 120 from being in a wet state for a long time and causing odor or bacteria.

[0227] In some examples, the base station may have a charging function. When the cleaning device is placed on the base station, the base station can be charged and automatically drained and filled. The base and base station may be separate structures, or the base and base station may be integrated, which is not limited in the embodiments of this application.
