Abstract
Description
Technical Field
[0001] This application relates to the field of cleaning technology, specifically to a floor brush assembly, cleaning equipment, and cleaning system. Background Technology
[0002] Cleaning equipment, such as floor scrubbers, is a type of cleaning machinery suitable for cleaning surfaces like floors and carpets. It simultaneously absorbs and removes wastewater from the site, offering advantages such as environmental friendliness, energy efficiency, and high performance. The roller brush is one of the key components of a floor scrubber; its main function is to clean the surface through mechanical rotation and friction.
[0003] As the roller brush wears down with prolonged use, the water stains left on the surface after cleaning increase significantly. Related technologies address this by installing a scraper behind the roller brush to remove water stains left on the surface as the cleaning device moves forward, thereby reducing watermarks and improving cleaning efficiency.
[0004] However, when the floor scrubber is pulled back, a lot of water stains remain on the surface to be cleaned, which can easily lead to a longer drying time and leave watermarks on the surface after drying, thus affecting the cleaning effect and efficiency. Utility Model Content
[0005] This application provides a floor brush component, cleaning equipment, and cleaning system that can solve the problem of water stains generated when the cleaning equipment is pulled back, resulting in reduced cleaning efficiency and cleaning effect.
[0006] In a first aspect, this application provides a floor brush component, which includes:
[0007] The main body of the floor brush;
[0008] A roller brush is disposed on the main body of the floor brush, and the roller brush rotates to clean the surface to be cleaned.
[0009] The front scraper is located at least partly in front of the roller brush along the forward direction of the brush body. The front scraper has only a flipping action relative to the brush body. The front scraper can rotate around its own length axis to switch between a first position and a second position.
[0010] When the front scraper is in the first position, the front scraper contacts the surface to be cleaned, so that when the floor brush body moves backward, the front scraper cleans the surface to be cleaned.
[0011] When the front scraper is in the second position, the front scraper contacts the roller brush to create a gap between the front scraper and the surface to be cleaned as the floor brush body moves forward, and the roller brush cleans the front scraper.
[0012] The floor brush assembly provided in this application has a front scraper that flips relative to the main body of the brush to switch between a first position and a second position. When the front scraper is flipped to the first position, it contacts the surface to be cleaned. Water stains generated by the roller brush on the surface can be scraped away by the front scraper as the main body of the brush moves backward, thereby reducing water residue on the surface and improving cleaning efficiency and effectiveness. Furthermore, when the main body of the brush moves to the bottom of a wall or encounters an obstacle, the front scraper can remove dirt from the bottom of the obstacle during the backward movement of the brush body, reducing hard-to-reach areas and improving cleaning results.
[0013] When the front squeegee is flipped to the second position, it comes into contact with the roller brush. On one hand, as the floor brush body moves forward, the roller brush rotates and contacts the front squeegee, cleaning at least the surface of the front squeegee facing the roller brush, thus achieving a self-cleaning function. Users don't need to manually clean the front squeegee, improving the user experience. On the other hand, there can be a relative force between the front squeegee and the roller brush. The front squeegee ensures that the liquid on the roller brush is evenly distributed across it, reducing the possibility of localized water stains on the surface to be cleaned due to excessive liquid concentration in certain areas.
[0014] Specifically, as the roller brush rotates past the distributor, the distributor sprays liquid onto the roller brush surface to wet it. The distributor has multiple spaced-apart spray holes for spraying liquid onto the roller brush surface. Therefore, it's easy to understand that the area on the roller brush directly opposite the spray holes has a higher liquid content than other areas. Consequently, when the roller brush moves across the surface to be cleaned, areas with higher liquid content will leave more watermarks, especially noticeable after prolonged use and wear. The front scraper, in its second position, contacts the roller brush, allowing for even water distribution.
[0015] The length of the front scraper is parallel to the axis of the roller brush. When the front scraper contacts the roller brush, it exerts a squeezing force on the brush bristles, allowing the liquid in areas with high liquid content to spread outwards. This improves the uniformity of liquid distribution on the roller brush, making it less likely for excessive water stains to remain on the surface to be cleaned. This reduces the likelihood of water stains forming on the surface at the source, and the possibility of watermarks forming after drying.
[0016] In summary, in this embodiment, when the floor brush body moves forward, the front scraper flips to contact the roller brush, ensuring even liquid distribution on the roller brush and reducing the likelihood of water stains (especially after wear) forming on the surface to be cleaned. Furthermore, during the forward movement of the floor brush body, the roller brush can at least clean the inner wall of the front scraper facing the roller brush, achieving a self-cleaning function for the front scraper. Moreover, when water stains are generated on the surface to be cleaned by the roller brush, the front scraper can flip to contact the surface during the reverse movement of the floor brush body, scraping away the water stains and improving cleaning efficiency and effectiveness.
[0017] It's important to note that when the front scraper is flipped to the second position, it contacts the roller brush, creating a gap between the front scraper and the surface to be cleaned. In other words, as the brush body moves forward, the front scraper does not contact the surface, preventing it from pushing dirt further away from the suction port and affecting cleaning efficiency. Furthermore, during suction operation, dirt on the surface can easily enter the suction port through the gap between the front scraper and the surface. In other words, the front scraper does not obstruct the suction of the surface.
[0018] It should be noted that the front scraper in this embodiment only has a flipping action. Therefore, the movement path of the front scraper is only a flipping motion around its own length axis. The movement mode of the front scraper is simple, and the reliability of the front scraper during the flipping process is high.
[0019] According to one embodiment of this application, when the front scraper is located in the first position, the front scraper is located on the front side of the roller brush along the forward direction of the brush body;
[0020] When the front scraper is in the second position, it overlaps with the roller brush along the forward direction of the brush body.
[0021] In this embodiment of the application, when the front scraper is in the first position, the front scraper can be located in front of the roller brush. Therefore, when the brush body moves backward, the roller brush can first clean the surface to be cleaned. Then, the front scraper can scrape off the water stains on the surface to be cleaned after the roller brush has cleaned it, so as to reduce the possibility that the roller brush leaves water stains on the surface to be cleaned when the brush body moves backward, which may affect the cleaning efficiency and cleaning effect.
[0022] When the front squeegee is in the second position, it can flip towards the roller brush, creating an overlapping area. Therefore, there is an interaction force between the front squeegee and the roller brush. On one hand, the force of the front squeegee on the roller brush helps to evenly distribute the water. The front squeegee can compress the liquid on the roller brush, ensuring a more uniform distribution and reducing the likelihood of localized water stains on the surface to be cleaned. On the other hand, the force of the roller brush on the front squeegee also cleans it. The increased cleaning force of the roller brush bristles enhances the removal of dirt from the front squeegee.
[0023] According to one embodiment of this application, when the front scraper is located in the first position, there is a gap between the front scraper and the roller brush;
[0024] When the front scraper is in the second position, the front scraper comes into contact with the bristles of the roller brush.
[0025] In this embodiment, when the front scraper is in the first position, it contacts the surface to be cleaned. This allows the front scraper to remove water stains or clean hard-to-reach areas as the brush body retracts. There is friction between the front scraper and the surface to be cleaned. The brush body experiences resistance during retraction. At this time, there is a gap between the front scraper and the roller brush, preventing them from contacting each other. This reduces the possibility that contact between the front scraper and the roller brush would increase resistance during retraction, thus affecting the brush's endurance.
[0026] When the front scraper is in the second position, the front scraper can deflect towards the direction of the roller brush bristles, so that part of the front scraper can extend into the interior of the roller brush bristles. Thus, the rotation of the roller brush allows the roller brush bristles to wipe the surface of the front scraper, achieving self-cleaning of the front scraper.
[0027] According to one embodiment of this application, the floor brush assembly includes a first rotating shaft connected to the floor brush body. The first rotating shaft extends along the length direction of the front scraper, and the front scraper rotates about the axial direction of the first rotating shaft to have a first position and a second position.
[0028] When the front scraper is in the first position and the second position, the horizontal height of the first rotating shaft remains unchanged.
[0029] In this embodiment, the front scraper can be rotatably connected to the floor brush body via a first rotating shaft to achieve the flipping action of the front scraper. By keeping the horizontal height of the first rotating shaft constant, the front scraper can maintain consistency each time it switches to the first position, ensuring the same contact depth between the front scraper and the surface to be cleaned. This satisfies the cleaning effect of scraping water stains or cleaning hard-to-reach areas, and reduces the possibility that changes in the horizontal height of the first rotating shaft could lead to insufficient contact depth between the front scraper and the surface to be cleaned when switching to the first position, thus requiring the user to calibrate the first position of the front scraper.
[0030] According to one embodiment of this application, when the front scraper is located in the first position and the second position, the position of the first rotating shaft remains unchanged along the forward direction of the brush body.
[0031] In this embodiment, by keeping the position of the first rotating shaft constant along the forward direction of the brush body, consistency can be ensured each time the front scraper bar switches to the second position. The front scraper bar and the roller brush have the same contact depth to satisfy the self-cleaning effect of the roller brush on the front scraper bar. This helps reduce the likelihood that changes in the position of the first rotating shaft in the forward direction of the brush body could lead to insufficient contact depth between the front scraper bar and the roller brush when switching to the second position, thus reducing the need for the user to calibrate the second position of the front scraper bar.
[0032] Therefore, when the front scraper only rotates relative to the brush body via the first rotating shaft, the horizontal height of the first rotating shaft and its position along the forward direction of the brush body can remain unchanged during the switching between the first and second positions. Thus, the state of the front scraper remains consistent when switching to the first position and when switching to the second position, thereby eliminating the need for frequent calibration of the first and second positions of the front scraper.
[0033] According to one embodiment of this application, the floor brush assembly further includes a transmission assembly connected to the front scraper, the transmission assembly being used to drive the front scraper to switch between the first position and the second position.
[0034] In this embodiment of the application, the transmission component can be used to drive the front scraper to switch from the first position to the second position, and the transmission component can also be used to drive the front scraper to switch from the second position to the first position.
[0035] The front scraper only has a flipping motion relative to the main body of the floor brush. Therefore, the transmission assembly can make the front scraper reciprocate axially around the first rotating shaft to achieve switching between the first position and the second position.
[0036] According to one embodiment of this application, the floor brush assembly further includes a roller brush cover, which is disposed on the floor brush body and covers at least a portion of the roller brush.
[0037] Along the forward direction of the brush body, part of the roller brush cover is located on the front side of the roller brush, and the front scraper is connected to the part of the roller brush cover located on the front side of the roller brush via the first rotating shaft.
[0038] In this embodiment, the brush cover can be used to shield at least part of the brush, so that the brush is protected from damage when encountering obstacles. Furthermore, the brush cover can provide stable support for structural components such as the front scraper.
[0039] Specifically, along the forward direction of the brush body, a portion of the roller brush cover is located at the front of the roller brush. Therefore, when the brush body encounters obstacles such as walls during its forward movement, the roller brush cover can first contact the wall, reducing the possibility of damage to the roller brush due to collision. Since a portion of the roller brush cover is located at the front of the roller brush, the front scraper can be positioned on the portion of the roller brush cover at the front of the roller brush via a first pivot. This allows at least a portion of the front scraper to be located at the front of the roller brush, so that when the front scraper is flipped to the first position, there can be a gap between the front scraper and the roller brush along the forward direction of the brush body. The front scraper can then scrape away any water residue left on the surface to be cleaned by the roller brush as the brush body retracts. Furthermore, when the front scraper is flipped to the second position, at least a portion of the front scraper can contact the bristles of the roller brush.
[0040] According to one embodiment of this application, the floor brush assembly further includes a power unit connected to at least one of the floor brush body and the roller brush cover, and the power unit is connected to the transmission assembly to provide the transmission assembly with a force to drive the front scraper to rotate.
[0041] In this embodiment, the power unit can be used to provide power for the rotation of the front scraper. The power unit is connected to the transmission assembly, so the transmission assembly can transmit the power provided by the power unit to the front scraper.
[0042] According to one embodiment of this application, the transmission assembly is provided with a first connecting portion, and the front scraper is provided with a second connecting portion. The first connecting portion is connected to the second connecting portion so that the transmission assembly is connected to the front scraper.
[0043] In this embodiment, the connection between the first connecting part and the second connecting part can be used to transmit power. By connecting the first connecting part and the second connecting part, the transmission component and the front scraper can be connected, so that when the power unit drives the transmission component to move, the transmission component can drive the front scraper to switch between the first position and the second position.
[0044] According to one embodiment of this application, the transmission assembly includes an elastic drive member and a transmission drive member;
[0045] The elastic drive member is connected to the front scraper and the roller brush cover, and the elastic drive member is used to drive the front scraper to move to the second position;
[0046] One end of the transmission drive is connected to the power unit, and the other end of the transmission drive is connected to the front scraper. The transmission assembly is used to overcome the force of the elastic drive to drive the front scraper to move toward the first position.
[0047] In this embodiment, the transmission drive and the elastic drive can be used to move the front scraper to a first position and a second position, respectively. In other words, the transmission drive and the elastic drive can cause the front scraper to flip in opposite directions.
[0048] The elastic drive component provides an elastic force to the front scraper, propelling it towards the second position. Under the action of the elastic drive component, the front scraper remains in contact with the roller brush, thus achieving self-cleaning of the front scraper by the roller brush. Specifically, the floor brush body is typically in a forward-moving state. Therefore, the elastic action of the elastic drive component keeps the front scraper in the second position, creating a gap between the front scraper and the surface to be cleaned during its forward movement. This gap allows dirt on the front side of the front scraper to be sucked into the suction port.
[0049] When the floor brush body is in the retracted position, the power unit can provide power to the transmission drive component, enabling the transmission drive component to overcome the elastic force exerted by the elastic drive component on the front scraper in the direction of the roller brush. The transmission drive component can then drive the front scraper to move away from the roller brush to reach the first position. At this time, the front scraper contacts the surface to be cleaned, thereby scraping away water stains generated by the roller brush on the surface to be cleaned during the retraction of the floor brush body.
[0050] According to one embodiment of this application, the transmission drive component is a flexible component, the transmission drive component is connected to the front scraper, and the power unit is used to drive the transmission drive component to have a tightened state and a released state.
[0051] When the transmission drive component is in the tightened state, the front scraper is located in the first position;
[0052] When the transmission drive is in the released state, the front scraper is located in the second position.
[0053] In this embodiment, when the transmission drive is in a tightened state, it provides a force to the front scraper to flip it away from the roller brush, and the force exerted by the transmission drive on the front scraper is greater than the elastic force exerted by the elastic drive on the front scraper. Therefore, the transmission drive can drive the front scraper to overcome the force of the elastic drive, thereby flipping the front scraper away from the roller brush, and the end of the front scraper away from the first rotating shaft can contact the surface to be cleaned.
[0054] When the drive unit is in the released state, it exerts no force on the front scraper. At this time, the elastic drive unit can drive the front scraper to flip towards the roller brush under its own elasticity, and the front scraper comes into contact with the roller brush.
[0055] It should be noted that the flexible component is bendable. Therefore, the transmission drive component is less affected by the structural layout of the roller brush cover and the floor brush body. The transmission drive component can make efficient use of the space on the roller brush cover and the floor brush body.
[0056] Furthermore, the drive mechanism is a flexible component that can provide tension. The drive mechanism can pull the front scraper away from the roller brush. When the drive mechanism is released, it can no longer provide pushing or pressing force; at this point, the elastic reset component can be used to move the front scraper towards the roller brush.
[0057] According to one embodiment of this application, the transmission drive is located in the middle region of the upper cover of the roller brush along the length direction of the front scraper.
[0058] In this embodiment, by positioning the transmission drive component in the middle region of the roller brush cover, the transmission drive component can apply force to the middle region of the front scraper along its length, thereby ensuring relatively uniform force distribution on the front scraper. During the flipping process of the front scraper, the middle and edge regions of the front scraper can maintain synchronous movement, which helps improve the stability of the front scraper during the flipping process.
[0059] Since the drive unit is located in the middle area of the roller brush cover, it can stably rotate the front scraper. Therefore, the number of drive units does not need to be multiple, which helps to reduce the structural complexity of the floor brush assembly and saves the space occupied by the drive unit.
[0060] According to one embodiment of this application, the first connecting portion is located at the end of the transmission drive member away from the power unit, and the transmission drive member can pass through the front scraper.
[0061] When the front scraper is in the first position, the first connecting part is connected to the second connecting part;
[0062] When the front scraper is in the second position, the first connecting part is away from the second connecting part.
[0063] In this embodiment, the transmission drive member can be inserted through the front scraper bar, such that the first connecting portion at the end of the transmission drive member and the second connecting portion on the front scraper bar are in a connected and unconnected state. When the transmission drive member is in a tightened state, the first connecting portion and the second connecting portion can be connected. The first connecting portion and the second connecting portion can transmit force, so that the front scraper bar can rotate around the first axis in the direction of the first position. When the transmission drive member is in a released state, the first connecting portion can hang down naturally under its own weight, and the first connecting portion and the second connecting portion are not connected. Therefore, the transmission drive member can exert no force on the front scraper bar. At this time, under the action of the elastic drive member, the front scraper bar can be located in the second position.
[0064] According to one embodiment of this application, the transmission assembly includes a drive arm, one end of which is connected to the power unit, and the other end of which is connected to the front scraper. The drive arm is used to drive the front scraper to rotate axially around the first rotating shaft to switch between the first position and the second position.
[0065] In this embodiment, the drive arm can be used to transmit power from the power unit. Since the drive arm is a rigid structure, it can provide both pulling and pushing forces to achieve the switching of the front scraper between a first and a second position through its reciprocating motion.
[0066] Specifically, the drive arm can provide a pulling force that moves the front scraper towards the roller brush, so that the front scraper can be flipped to the second position. The drive arm can also provide a pushing force that moves the front scraper away from the roller brush, so that the front scraper can be flipped to the second position.
[0067] According to one embodiment of this application, the transmission assembly includes a second rotating shaft, and the drive arm is rotatably connected to the second rotating shaft. The drive arm rotates clockwise or counterclockwise around the second rotating shaft to drive the front scraper to switch between the first position and the second position.
[0068] In this embodiment of the application, the drive arm can perform reciprocating motion around the second rotating axis in a forward or reverse direction to achieve the switching of the front scraper in the first position and the second position.
[0069] Specifically, when the drive arm rotates clockwise around the second pivot, the end of the drive arm connected to the front scraper can be flipped towards the surface to be cleaned. The drive arm can also cause the front scraper to flip towards the surface to be cleaned, so that the front scraper can contact the surface to be cleaned and the front scraper can be in the first position.
[0070] When the drive arm rotates counterclockwise around the second pivot, the end of the drive arm connected to the front scraper can deflect away from the surface to be cleaned. The drive arm can cause the front scraper to flip away from the surface to be cleaned, so that the front scraper can have a gap with the surface to be cleaned, and the front scraper contacts the roller brush. At this time, the front scraper is in the second position.
[0071] According to one embodiment of this application, the floor brush body includes a support arm for fixing the roller brush, and the support arm is disposed near the end of the floor brush body along the length direction of the front scraper.
[0072] The second pivot is disposed on the support arm.
[0073] In this embodiment, the support arm can be used to fix the roller brush. The transmission assembly can be connected to the support arm via a second rotating shaft. The support arm can provide support for the transmission assembly. Therefore, the brush body does not need an additional structure for fixing the transmission assembly, which helps reduce the complexity of the brush assembly structure.
[0074] It is easy to understand that, since the drive arm is a rigid structure, it has good strength. Therefore, when the drive arm is set at the end of the brush body, it can also make the front scraper blade have good stability during the flipping process, so as to improve the reliability of the front scraper blade switching between the first position and the second position.
[0075] According to one embodiment of this application, the first connecting portion is located on the drive arm, and the second connecting portion is located on the front scraper.
[0076] One of the first connecting part and the second connecting part is a sliding groove, and the other of the first connecting part and the second connecting part is a sliding column. The sliding column slides in the sliding groove so that when the drive arm rotates in the forward or reverse direction, the second connecting part drives the front scraper to rotate axially around the first rotating shaft.
[0077] In this embodiment, when the drive arm rotates clockwise around the second rotating shaft, the sliding column can rotate counterclockwise relative to the axial direction of the first rotating shaft through the coordinated movement of the sliding column and the sliding groove. This allows the front scraper to rotate counterclockwise relative to the axial direction of the first rotating shaft, and the portion of the front scraper away from the first rotating shaft can move away from the roller brush. At this time, the front scraper can move towards the first position.
[0078] When the drive arm rotates counterclockwise around the second pivot, the sliding column and the sliding groove work together to allow the sliding column to rotate clockwise relative to the axial direction of the first pivot, so that the front scraper can rotate clockwise relative to the axial direction of the first pivot. The part of the front scraper away from the first pivot can move towards the roller brush. At this time, the front scraper can move towards the second position.
[0079] Secondly, this application provides a cleaning device comprising:
[0080] body;
[0081] The floor brush assembly described in any of the above embodiments is connected to the body.
[0082] Thirdly, the cleaning system provided in this application includes:
[0083] Base station or base station;
[0084] And cleaning equipment, which can be placed on a base or base station.
[0085] The beneficial effects of the floor brush assembly provided in this application are as follows: the front scraper has a flipping action relative to the floor brush body and can switch between a first position and a second position. Therefore, when the front scraper is in the first position, by contacting the surface to be cleaned, the front scraper can remove water stains generated by the roller brush on the surface to be cleaned as the floor brush body moves backward, thereby reducing the possibility of water stains remaining on the surface to be cleaned and causing watermarks. Furthermore, when the floor brush body moves to the bottom of the wall or encounters an obstacle, the front scraper can remove dirt from the bottom of the obstacle during the retraction of the floor brush body, thereby reducing hard-to-clean areas and improving the cleaning effect.
[0086] When the front squeegee is in the second position, it is in contact with the roller brush. Therefore, as the roller brush rotates, it can clean at least the surface of the front squeegee facing the roller brush, achieving a self-cleaning function, thus eliminating the need for manual cleaning. Furthermore, the contact between the front squeegee and the roller brush, and the relative force between them, ensures that the liquid on the roller brush is evenly distributed, reducing the possibility of localized high liquid content and water stains on the surface to be cleaned, thereby improving cleaning effectiveness.
[0087] In particular, as the roller brush wears down over time, more watermarks will remain on the surface to be cleaned. By having the front scraper contact the roller brush in the second position, the water can be evenly distributed across the brush.
[0088] In addition to the technical problems solved by the embodiments of the present invention, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that can be solved by the floor brush components, cleaning equipment, and cleaning systems provided by the embodiments of the present invention, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific embodiments.

[0114] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0115] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. Clearly, the described embodiments are only a portion, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0116] This application provides a cleaning device, which may be, but is not limited to, a floor scrubber. This application uses a floor scrubber as an example. A floor scrubber is a device used for cleaning floors and generally consists of multiple parts such as a brush assembly, a roller brush, a clean water tank, and a wastewater tank. The working principle of the floor scrubber is as follows: the high-speed rotation of the motor drives the roller brush to rotate at high speed, while the clean water tank rotates, spraying clean water forward onto the roller brush through a water path. In conjunction with the high-speed rotation of the roller brush, wastewater is drawn into the wastewater tank through a vacuum suction channel located behind the roller brush and another water path, thus completing the cleaning process.
[0117] The roller brush is one of the key components of a floor scrubber, its main function being to clean the surface through mechanical rotation and friction. When the roller brush wears down with prolonged use, the water stains left on the surface after cleaning will significantly increase. Related technologies utilize scrapers installed behind the roller brush to remove water stains left on the surface as the cleaning equipment moves forward, thereby reducing watermarks and improving cleaning efficiency.
[0118] Floor scrubbers have forward and reverse motion. In normal operation, users can push the scrubber forward. The scraper behind the roller brush removes water residue from the surface as the scrubber moves forward. When the scrubber encounters obstacles such as walls, users can pull it back to reverse. However, when pulling the scrubber back, water residue remains on the surface, especially after prolonged use and brush wear. This residue increases drying time and can leave watermarks, affecting cleaning effectiveness and efficiency.
[0119] Based on the aforementioned technical problems, the applicant has improved the structure of existing floor brush components. In the embodiments of this application, the floor brush component includes a front scraper. Along the forward direction of the floor brush body, at least part of the front scraper is located on the front side of the roller brush. Therefore, when the floor brush component retracts, after the roller brush cleans the surface to be cleaned, the front scraper can scrape away water stains on the surface to be cleaned, thereby reducing or eliminating water stains on the surface to be cleaned. This improves the drying efficiency of the surface to be cleaned, thus improving cleaning efficiency. Furthermore, once the surface to be cleaned is dry, watermarks are less likely to remain, which is beneficial for improving the cleaning effect.
[0120] Furthermore, the front scraper in this embodiment has a flipping action. The front scraper can flip to a first position and a second position. When the front scraper is in the first position, it can contact the surface to be cleaned, so that when the brush body moves backward, the front scraper can roll and scrape away water stains left on the surface to be cleaned, thereby improving drying efficiency and cleaning efficiency. When the front scraper is in the second position, it can contact the roller brush, and the rotation of the roller brush can clean the front scraper. Furthermore, the front scraper can evenly distribute water on the roller brush, making the liquid distribution on the roller brush uniform, thereby reducing the possibility of generating excessive water stains on the surface to be cleaned from the source of the roller brush, thus improving cleaning efficiency and cleaning effect.
[0121] The floor brush assembly 100, cleaning equipment, and cleaning system provided in this application are described below with reference to the accompanying drawings and specific embodiments.
[0122] See Figures 1 to 3 As shown, the floor brush assembly 100 of this application embodiment includes a floor brush body 110, a roller brush 120, and a front scraper 130.
[0123] A roller brush 120 is disposed on the floor brush body 110. The roller brush 120 rotates to clean the surface to be cleaned. Along the forward direction of the floor brush body 110, at least a portion of the front scraper 130 is located in front of the roller brush 120. The front scraper 130 only has a flipping motion relative to the floor brush body 110. The front scraper 130 can rotate about its own length direction Z axis to switch between a first position and a second position.
[0124] When the front scraper 130 is in the first position, it contacts the surface to be cleaned, so that it can clean the surface when the brush body 110 moves backward. When the front scraper 130 is in the second position, it contacts the roller brush 120, so that a gap is created between the front scraper 130 and the surface to be cleaned when the brush body 110 moves forward, and the roller brush 120 cleans the front scraper 130.
[0125] In this embodiment, the front scraper 130 has a flipping action relative to the brush body 110 to switch between a first position and a second position. When the front scraper 130 is flipped to the first position, it contacts the surface to be cleaned. Water stains generated by the roller brush 120 on the surface to be cleaned can be scraped away by the front scraper 130 when the brush body 110 moves backward, thereby reducing water residue on the surface and improving cleaning efficiency and effect. Furthermore, when the brush body 110 moves to the bottom of a wall or encounters an obstacle, the front scraper 130 can remove dirt from the bottom of the obstacle during the backward movement, reducing blind spots and improving cleaning effect.
[0126] When the front squeegee 130 is flipped to the second position, it comes into contact with the roller brush 120. On one hand, as the floor brush body 110 moves forward, the roller brush 120 rotates and comes into contact with the front squeegee 130, effectively cleaning the surface of the front squeegee 130 facing the roller brush 120. This achieves a self-cleaning function for the front squeegee 130, eliminating the need for manual cleaning and improving the user experience. On the other hand, there can be a relative force between the front squeegee 130 and the roller brush 120. The front squeegee 130 ensures that the liquid on the roller brush 120 is evenly distributed across it, reducing the possibility of excessive liquid in certain areas and causing water stains on the surface to be cleaned.
[0127] Specifically, when the roller brush 120 rotates past the distributor (not shown in the figure), the distributor can spray liquid onto the surface of the roller brush 120 to wet it. The distributor has multiple spaced-apart spray holes for spraying liquid onto the surface of the roller brush 120. Therefore, it is easy to understand that the liquid content in the area of the roller brush 120 directly opposite the spray holes is higher than that in other areas. As a result, when the roller brush 120 moves across the surface to be cleaned, the areas with higher liquid content will leave more watermarks on the surface, especially after the roller brush 120 has been used and worn for a long time, the watermarks left on the surface to be cleaned will become more obvious. When the front scraper 130 is in the second position and contacts the roller brush 120, the front scraper 130 can distribute water evenly on the roller brush 120.
[0128] The longitudinal direction Z of the front scraper 130 is parallel to the axial direction of the roller brush 120. When the front scraper 130 contacts the roller brush 120, the front scraper 130 can exert a squeezing force on the bristles of the roller brush 120, so that the liquid in the area with high liquid content on the roller brush 120 can be diffused to the surrounding area. This can improve the uniformity of liquid distribution on the roller brush 120, making it less likely for the roller brush 120 to leave excessive water stains in some areas on the surface to be cleaned. In this way, the possibility of water stains forming on the surface to be cleaned can be reduced from the source, and the possibility of water stains forming watermarks after drying can be reduced.
[0129] In summary, in this embodiment, when the floor brush body 110 moves forward, the front scraper 130 flips to contact the roller brush 120, which allows for a more even distribution of liquid on the roller brush 120, thereby reducing the likelihood of water stains forming on the surface to be cleaned (especially after wear) by the roller brush 120. Furthermore, during the forward movement of the floor brush body 110, the roller brush 120 can at least clean the inner wall of the front scraper 130 facing the roller brush 120, achieving a self-cleaning function for the front scraper 130. Moreover, when water stains are formed on the surface to be cleaned by the roller brush 120, during the backward movement of the floor brush body 110, the front scraper 130 can flip to contact the surface to be cleaned, allowing it to scrape away the water stains, thus improving cleaning efficiency and effectiveness.
[0130] It should be noted that when the front scraper 130 is flipped to the second position, it contacts the roller brush 120, creating a gap between the front scraper 130 and the surface to be cleaned. In other words, when the brush body 110 moves forward, the front scraper 130 does not contact the surface to be cleaned, thus preventing it from pushing dirt forward and causing it to move further away from the suction port, affecting the cleaning effect. Furthermore, when the brush body 110 performs suction, dirt on the surface to be cleaned can easily enter the suction port through the gap between the front scraper 130 and the surface. In other words, the front scraper 130 does not obstruct the suction of the surface to be cleaned.
[0131] It should be noted that the front scraper 130 in this embodiment of the application only has a flipping action. Therefore, the movement path of the front scraper 130 is only flipping around the axis of rotation in its own length direction Z. The movement mode of the front scraper 130 is simple, and the reliability of the front scraper 130 in the flipping process is high.
[0132] See also some of the possible implementation methods. Figures 2 to 5 As shown, in this embodiment of the application, when the front scraper 130 is in the first position, it is located in front of the roller brush 120 along the forward direction of the brush body 110. When the front scraper 130 is in the second position, it overlaps with the roller brush 120 along the forward direction of the brush body 110.
[0133] In the embodiments of this application, see Figure 2 and Figure 4As shown, when the front scraper 130 is in the first position, the front scraper 130 can be located in front of the roller brush 120. Therefore, when the floor brush body 110 moves backward, the roller brush 120 can first clean the surface to be cleaned. Then, the front scraper 130 can scrape off the water stains on the surface to be cleaned after the roller brush 120 has cleaned it, so as to reduce the possibility that the roller brush 120 will leave water stains on the surface to be cleaned when the floor brush body 110 moves backward, which may affect the cleaning efficiency and cleaning effect.
[0134] See Figure 3 and Figure 5 As shown, when the front squeegee 130 is in the second position, it can flip towards the roller brush 120, creating an overlapping area between them. Therefore, there is an interaction force between the front squeegee 130 and the roller brush 120. On one hand, the force exerted by the front squeegee 130 on the roller brush 120 can evenly distribute the liquid. The front squeegee 130 can compress the liquid on the roller brush 120, ensuring a uniform distribution and reducing the likelihood of localized water stains on the surface to be cleaned. On the other hand, the force exerted by the roller brush 120 on the front squeegee 130 can clean the front squeegee 130. The increased cleaning force of the roller brush 120 bristles on the front squeegee 130 enhances the cleaning effect on the dirt on the front squeegee 130.
[0135] See also some of the possible implementation methods. Figure 4 and Figure 5 As shown, in this embodiment of the application, when the front scraper 130 is in the first position, there is a gap between the front scraper 130 and the roller brush 120. When the front scraper 130 is in the second position, the front scraper 130 is in contact with the bristles of the roller brush 120.
[0136] In this embodiment, when the front scraper 130 is in the first position, the front scraper 130 is in contact with the surface to be cleaned, so that when the brush body 110 retracts, the front scraper 130 can be used to scrape away water stains or clean hard-to-reach areas. There is friction between the front scraper 130 and the surface to be cleaned. There is resistance during the retraction of the brush body 110. At this time, there is a gap between the front scraper 130 and the roller brush 120, which prevents them from contacting each other. This reduces the possibility that contact between the front scraper 130 and the roller brush 120 would increase resistance during retraction and affect the brush's endurance.
[0137] When the front scraper 130 is in the second position, the front scraper 130 can be deflected toward the bristles of the roller brush 120 so that part of the front scraper 130 can extend into the interior of the bristles of the roller brush 120. Thus, the rotation of the roller brush 120 allows the bristles of the roller brush 120 to wipe the surface of the front scraper 130, thereby achieving self-cleaning of the front scraper 130.
[0138] In some examples, when the front squeegee 130 is in the first position, the angle between the portion of the front squeegee 130 closest to the surface to be cleaned and the surface to be cleaned can tend to be perpendicular. For example, this angle can be between 70° and 110°.
[0139] See also some of the possible implementation methods. Figure 6 As shown, the floor brush assembly 100 of this application embodiment may include a first rotating shaft 140. The first rotating shaft 140 is connected to the floor brush body 110. The first rotating shaft 140 extends along the length direction Z of the front scraper 130. The front scraper 130 rotates about the axial direction of the first rotating shaft 140 to have a first position and a second position.
[0140] When the front scraper 130 is in the first position and the second position, the horizontal height of the first rotating shaft 140 remains unchanged.
[0141] In this embodiment, the front scraper 130 is rotatably connected to the floor brush body 110 via the first rotating shaft 140 to achieve the flipping action of the front scraper 130. By keeping the horizontal height of the first rotating shaft 140 constant, the front scraper 130 can maintain consistency each time it switches to the first position, ensuring that the front scraper 130 has the same contact depth with the surface to be cleaned. This satisfies the cleaning effect of scraping water stains or cleaning hard-to-reach areas, and helps reduce the possibility that changes in the horizontal height of the first rotating shaft 140 may cause the contact depth between the front scraper 130 and the surface to be cleaned to be insufficient for the cleaning effect when switching to the first position, thus requiring the user to calibrate the first position of the front scraper 130.
[0142] In some examples, one end of the front scraper 130 is connected to the first rotating shaft 140, and the other end of the front scraper 130 can be a free end 130a for contact with the surface to be cleaned or the bristles of the roller brush 120. The horizontal height of the free end 130a of the front scraper 130 can change during the flipping process.
[0143] The horizontal height of the free end 130a of the front scraper 130 when it is in the first position is less than the horizontal height of the free end 130a of the front scraper 130 when it is in the second position.
[0144] See also some of the possible implementation methods. Figure 4 and Figure 5As shown, when the front scraper 130 of this application embodiment is in the first position and the second position, the position of the first rotating shaft 140 remains unchanged along the forward direction of the floor brush body 110.
[0145] In this embodiment, by keeping the position of the first rotating shaft 140 constant along the forward direction of the brush body 110, the front scraper 130 can be consistently positioned each time it switches to the second position. The front scraper 130 and the roller brush 120 have the same contact depth to ensure the self-cleaning effect of the roller brush 120 on the front scraper 130. This reduces the likelihood that when the position of the first rotating shaft 140 changes in the forward direction of the brush body 110, the contact depth between the front scraper 130 and the roller brush 120 may be insufficient to achieve the desired cleaning effect, thus reducing the need for the user to calibrate the second position of the front scraper 130.
[0146] Therefore, when the front scraper 130 only has a flipping action relative to the brush body 110 via the first rotating shaft 140, the horizontal height of the first rotating shaft 140 and the position of the first rotating shaft 140 along the forward direction of the brush body 110 can remain unchanged during the switching process of the front scraper 130 to the first position and the second position. Thus, the state of the front scraper 130 can remain consistent when switching to the first position and when switching to the second position, so that the first and second positions of the front scraper 130 do not need to be frequently calibrated.
[0147] See also some of the possible implementation methods. Figure 4 and Figure 5 As shown, the floor brush assembly 100 in this embodiment of the application further includes a transmission assembly 150. The transmission assembly 150 is connected to the front scraper 130. The transmission assembly 150 is used to drive the front scraper 130 to switch between a first position and a second position.
[0148] In this embodiment of the application, the transmission component 150 can be used to drive the front scraper 130 to switch from the first position to the second position, and the transmission component 150 can also be used to drive the front scraper 130 to switch from the second position to the first position.
[0149] In some examples, the front scraper 130 only has a flipping motion relative to the brush body 110. Therefore, the transmission assembly 150 can cause the front scraper 130 to reciprocate axially about the first pivot 140 to switch between a first position and a second position.
[0150] In some examples, the brush body 110 is typically in a forward-moving state; therefore, the front squeegee 130 can typically be in a second position to reduce the likelihood of the front squeegee 130 contacting the surface to be cleaned, thus preventing it from pushing dirt away from the front of the brush body 110. The second position can be the initial position of the front squeegee 130. The drive assembly 150 can drive the front squeegee 130 to switch to the first position when the brush body 110 is reversing, and reset the front squeegee 130 to the second position when the brush body 110 moves forward.
[0151] In some examples, this embodiment does not limit the specific structure and movement of the transmission component 150.
[0152] See also some of the possible implementation methods. Figure 4 and Figure 5 As shown, the front scraper 130 in this embodiment may include an adapter 131. The front scraper 130 can be connected to the first rotating shaft 140 via the adapter 131. The adapter 131 is connected to the transmission assembly 150. The transmission assembly 150 drives the front scraper 130 to switch between a first position and a second position via the adapter 131.
[0153] In this embodiment, on one hand, the adapter 131 can be used to transmit the force of the transmission assembly 150 to apply the force to the front scraper 130, thereby allowing the front scraper 130 to switch between a first position and a second position. On the other hand, the adapter 131 can be used to convert the direction of the force of the transmission assembly 150 into the direction of the flipping action of the front scraper 130.
[0154] In some examples, one side of the adapter 131 is connected to the transmission assembly 150, the other side of the adapter 131 is connected to the front scraper 130, and the adapter 131 can be rotated about the axial direction of the first rotating shaft 140 so that the front scraper 130 can be rotated about the axial direction of the first rotating shaft 140.
[0155] See also some of the possible implementation methods. Figure 4 and Figure 5 As shown, the floor brush assembly 100 of this embodiment further includes a roller brush cover 160. The roller brush cover 160 is disposed on the floor brush body 110. The roller brush cover 160 covers at least a portion of the roller brush 120. Along the forward direction of the floor brush body 110, a portion of the roller brush cover 160 is located in front of the roller brush 120. The front scraper 130 is connected to the portion of the roller brush cover 160 located in front of the roller brush 120 via a first pivot 140.
[0156] In this embodiment, the brush cover 160 can be used to shield at least part of the brush 120 so that the brush 120 is not easily damaged when encountering obstacles. Furthermore, the brush cover 160 can provide stable support for structural components such as the front scraper 130.
[0157] Specifically, along the forward direction of the brush body 110, a portion of the roller brush cover 160 is located in front of the roller brush 120. Therefore, when the brush body 110 encounters obstacles such as walls during its forward movement, the roller brush cover 160 can first contact the wall, reducing the possibility of the roller brush 120 being damaged due to a collision with the wall. Since a portion of the roller brush cover 160 is located in front of the roller brush 120, the front scraper 130 can be positioned on the portion of the roller brush cover 160 located in front of the roller brush 120 via the first pivot 140, so that at least a portion of the front scraper 130 can be located in front of the roller brush 120. Thus, when the front scraper 130 is flipped to the first position, there can be a gap between the front scraper 130 and the roller brush 120 along the forward direction of the brush body 110. The front scraper 130 can scrape away water stains remaining on the surface to be cleaned by the roller brush 120 when the brush body 110 is retracted. Furthermore, when the front scraper 130 is flipped to the second position, at least a portion of the front scraper 130 can come into contact with the bristles of the roller brush 120.
[0158] In some examples, the portion of the roller brush cover 160 located in front of the roller brush 120 may have space for mounting the front scraper 130. When the front scraper 130 is in a first position, it can be located within the space between the roller brush cover 160 and the surface to be cleaned. When the front scraper 130 is in a second position, it can be located within the space between the roller brush cover 160 and the roller brush 120. Therefore, by positioning the front scraper 130 in the portion of the roller brush cover 160 located in front of the roller brush 120, the front scraper 130 can make efficient use of the space in front of the roller brush 120, and can achieve cleaning without occupying additional space on the brush body 110.
[0159] See also some of the possible implementation methods. Figure 1 As shown, the floor brush assembly 100 in this embodiment of the application further includes a power unit 170. The power unit 170 is connected to at least one of the floor brush body 110 and the roller brush cover 160. The power unit 170 is connected to the transmission assembly 150 to provide the transmission assembly 150 with a force to drive the front scraper 130 to rotate.
[0160] In this embodiment, the power unit 170 can be used to provide power for the rotation of the front scraper 130. The power unit 170 is connected to the transmission assembly 150, so the transmission assembly 150 can transmit the power provided by the power unit 170 to the adapter 131, and transmit the power to the front scraper 130 through the adapter 131.
[0161] In some examples, the power unit 170 may be, but is not limited to, an electric motor. The power unit 170 may drive the transmission assembly 150 to move. The transmission assembly 150 may drive the adapter 131 to move such that the adapter 131 may cause the front scraper 130 to flip.
[0162] In some examples, the power unit 170 may be disposed on at least one of the brush body 110 and the roller cover 160.
[0163] See also some of the possible implementation methods. Figure 4 and Figure 5 As shown, the transmission assembly 150 of this embodiment has a first connecting portion 1521. The front scraper 130 has a second connecting portion 132. The first connecting portion 1521 is connected to the second connecting portion 132 so that the transmission assembly 150 is connected to the front scraper 130.
[0164] In this embodiment, the connection between the first connecting portion 1521 and the second connecting portion 132 can be used to transmit power. The connection between the first connecting portion 1521 and the second connecting portion 132 enables the connection between the transmission assembly 150 and the front scraper 130. The second connecting portion 132 can be disposed on the adapter 131 of the front scraper 130. When the power unit 170 drives the transmission assembly 150 to move, the connection between the transmission assembly 150 and the adapter 131 allows the adapter 131 to drive the front scraper 130 to switch between a first position and a second position.
[0165] In this embodiment, the structure of the first connecting part 1521 and the second connecting part 132 is not limited.
[0166] See also some of the possible implementation methods. Figures 4 to 6 As shown, the transmission assembly 150 includes an elastic drive member 151 and a transmission drive member 152. The elastic drive member 151 is connected to the front scraper 130 and the roller brush cover 160. The elastic drive member 151 drives the front scraper 130 to move to a second position. One end of the transmission drive member 152 is connected to the power unit 170. The other end of the transmission drive member 152 is connected to the front scraper 130. The transmission assembly 150 is used to overcome the force of the elastic drive member 151 to drive the front scraper 130 to move to a first position.
[0167] In this embodiment, the transmission drive 152 and the elastic drive 151 can be used to move the front scraper 130 to a first position and a second position, respectively. In other words, the transmission drive 152 and the elastic drive 151 can cause the front scraper 130 to flip in opposite directions.
[0168] The elastic drive member 151 provides an elastic force to the front scraper 130, propelling it towards the second position. Under the action of the elastic drive member 151, the front scraper 130 remains in contact with the roller brush 120, thus achieving self-cleaning of the front scraper 130 by the roller brush 120. Specifically, the floor brush body 110 is typically in a forward-moving state. Therefore, the elastic action of the elastic drive member 151 keeps the front scraper 130 in the second position. During the forward movement of the front scraper 130, a gap exists between the front scraper 130 and the surface to be cleaned, allowing dirt on the front side of the front scraper 130 to be sucked into the suction port through the gap.
[0169] When the floor brush body 110 is in the retracted position, the power unit 170 can provide power to the transmission drive 152, so that the transmission drive 152 can overcome the elastic force exerted by the elastic drive 151 on the front scraper 130 in the direction of the roller brush 120. The transmission drive 152 can drive the front scraper 130 to move away from the roller brush 120 to reach the first position. At this time, the front scraper 130 contacts the surface to be cleaned, so as to scrape away the water stains generated by the roller brush 120 on the surface to be cleaned during the retraction of the floor brush body 110.
[0170] See also some of the possible implementation methods. Figure 4 and Figure 5 As shown, the transmission drive component 152 is a flexible component. The transmission drive component 152 is connected to the front scraper 130. The power unit 170 drives the transmission drive component 152 to have a tightened state and a released state. When the transmission drive component 152 is in the tightened state, the front scraper 130 is in a first position. When the transmission drive component 152 is in the released state, the front scraper 130 is in a second position.
[0171] In the embodiments of this application, see Figure 4 As shown, when the transmission drive 152 is in the tightened state, it can provide a force to the front scraper 130 to flip it away from the roller brush 120, and the force exerted by the transmission drive 152 on the front scraper 130 is greater than the elastic force exerted by the elastic drive 151 on the front scraper 130. Therefore, the transmission drive 152 can drive the front scraper 130 to overcome the force of the elastic drive 151, so as to flip the front scraper 130 away from the roller brush 120, and the end of the front scraper 130 away from the first rotating shaft 140 can contact the surface to be cleaned.
[0172] See Figure 5 As shown, when the transmission drive 152 is in the released state, the transmission drive 152 does not exert any force on the front scraper 130. At this time, the elastic drive 151 can drive the front scraper 130 to flip towards the roller brush 120 under its own elasticity, and the front scraper 130 contacts the roller brush 120.
[0173] It should be noted that the flexible component is bendable. Therefore, the transmission drive component 152 is not easily affected by the structural layout of the roller brush cover 160 and the floor brush body 110. The transmission drive component 152 can make reasonable use of the space on the roller brush cover 160 and the floor brush body 110.
[0174] Furthermore, the transmission drive 152 is a flexible component that can provide tension. The transmission drive 152 can pull the front scraper 130 to move away from the roller brush 120. When the transmission drive 152 is released, it can no longer provide pushing or pressing force. At this time, the elastic reset component can be used to move the front scraper 130 towards the roller brush 120.
[0175] In some examples, the floor brush assembly 100 may also include a retractor 180. A drive mechanism 152 may be wound around the retractor 180. The retractor 180 may be connected to a power unit 170. The power unit 170 may drive the retractor 180 to rotate forward or backward so that the drive mechanism 152 on the retractor 180 is in a tightened or released state, thereby enabling the front wiper blade 130 to switch between a first position and a second position.
[0176] In some examples, the drive element 152 may be, but is not limited to, a steel wire. The steel wire may have good strength to provide a force for the front scraper 130 to flip in the direction of the first position.
[0177] In some examples, the elastic actuator 151 may be, but is not limited to, a torsion spring. One arm of the elastic actuator 151 is connected to the brush cover 160, and the other arm of the elastic actuator 151 is connected to the front scraper 130. For example, the other arm of the elastic actuator 151 may be connected to the front scraper 130 via an adapter 131.
[0178] See also some of the possible implementation methods. Figure 1 As shown, along the length direction Z of the front scraper 130, the transmission drive 152 is located in the middle area of the upper cover 160 of the roller brush.
[0179] In this embodiment, by positioning the transmission drive 152 in the middle region of the roller brush cover 160, the transmission drive 152 can apply force to the middle region of the front scraper 130 along the length direction Z, so that the force on the front scraper 130 can be relatively uniform. During the flipping process of the front scraper 130, the middle region and the edge region of the front scraper 130 can maintain synchronous movement, which is beneficial to improving the stability of the front scraper 130 during the flipping process.
[0180] Since the transmission drive unit 152 is located in the middle area of the roller brush cover 160, it can make the front scraper 130 rotate stably. Therefore, the number of transmission drive units 152 does not need to be set to multiple, which helps to reduce the structural complexity of the floor brush assembly 100 and save the space occupied by the transmission drive unit 152.
[0181] In some examples, the elastic drive member 151 may be disposed in the edge region of the front wiper bar 130. Exemplarily, the number of elastic drive members 151 may be two. The two elastic drive members 151 may be located in the two side edge regions of the front wiper bar 130, respectively.
[0182] See also some of the possible implementation methods. Figure 4 and Figure 5 As shown, the first connecting portion 1521 is located at the end of the transmission drive member 152 away from the power unit 170. The transmission drive member 152 can pass through the front scraper 130. When the front scraper 130 is in the first position, the first connecting portion 1521 is connected to the second connecting portion 132. When the front scraper 130 is in the second position, the first connecting portion 1521 is away from the second connecting portion 132.
[0183] In this embodiment, the transmission drive member 152 can be inserted through the front scraper 130, such that the first connecting portion 1521 at the end of the transmission drive member 152 and the second connecting portion 132 on the front scraper 130 are in a connected and unconnected state. When the transmission drive member 152 is in a tightened state, the first connecting portion 1521 and the second connecting portion 132 can be connected. The first connecting portion 1521 and the second connecting portion 132 can transmit force so that the front scraper 130 can rotate around the first rotating shaft 140 towards a first position. When the transmission drive member 152 is in a released state, the first connecting portion 1521 can hang down naturally under its own weight, and the first connecting portion 1521 and the second connecting portion 132 are not connected. Therefore, the transmission drive member 152 may not exert any force on the front scraper 130. At this time, under the action of the elastic drive member 151, the front scraper 130 can be located in a second position.
[0184] In some examples, the drive member 152 can pass through the adapter 131 of the front scraper 130. Therefore, the adapter 131 has a through hole 131a through which the drive member 152 can pass. The first connecting portion 1521 can be located on the side of the adapter 131 facing away from the roller brush 120 and close to the through hole 131a. The size of the first connecting portion 1521 can be larger than the size of the through hole 131a so that when the drive member 152 is in the tightened state, the first connecting portion 1521 can not easily pass through the through hole 131a to reach the side of the adapter 131 facing the roller brush 120. When the first connecting portion 1521 and the second connecting portion 132 are connected, the first connecting portion 1521 and the second connecting portion 132 can hook together. Therefore, when the first connecting part 1521 continues to tighten, the first connecting part 1521 can drive the second connecting part 132 to rotate axially relative to the first rotating shaft 140, so that the adapter 131 can rotate axially relative to the first rotating shaft 140, thereby allowing the front scraper 130 to rotate towards the first position.
[0185] In some examples, the second connecting portion 132 may have an internal space that accommodates at least a portion of the first connecting portion 1521. When the first connecting portion 1521 is connected to the second connecting portion 132, the first connecting portion 1521 may be located within the internal space of the second connecting portion 132. The first connecting portion 1521 and the second connecting portion 132 may interlock. For example, the second connecting portion 132 may have a stepped portion for engaging the first connecting portion 1521.
[0186] In some examples, the adapter 131 may be provided with a winding portion. The portion of the transmission drive 152 near the first connecting portion 1521 may be wound around the winding portion so that the adapter 131 can be rotated about the axial direction of the first rotating shaft 140 during the tightening of the transmission drive 152.
[0187] In some examples, the extension direction of the through hole 131a on the adapter 131 through which the transmission drive 152 passes can be arc-shaped.
[0188] See also some of the possible implementation methods. Figures 7 to 9 As shown, the transmission assembly 150 of this embodiment includes a drive arm 153. One end of the drive arm 153 is connected to the power unit 170. The other end of the drive arm 153 is connected to the front scraper 130. The drive arm 153 is used to drive the front scraper 130 to rotate axially about the first rotating shaft 140, so as to switch between a first position and a second position.
[0189] In this embodiment, the drive arm 153 can be used to transmit power to the power unit 170. Since the drive arm 153 is a rigid structure, it can provide both pulling and pushing forces to achieve the switching of the front scraper 130 between a first position and a second position through the reciprocating motion of the drive arm 153.
[0190] Specifically, the drive arm 153 can provide a pulling force that moves the front scraper 130 toward the roller brush 120, so that the front scraper 130 can be flipped to the second position. The drive arm 153 can also provide a pushing force that moves the front scraper 130 away from the roller brush 120, so that the front scraper 130 can be flipped to the second position.
[0191] In some examples, the drive arm 153 can be directly connected to the power unit 170, or the drive arm 153 can be connected to the power unit 170 via the connecting arm 155.
[0192] In some examples, the drive arm 153 can be directly connected to the front scraper 130, or the drive arm 153 can be connected to the front scraper 130 via an adapter 131.
[0193] See also some of the possible implementation methods. Figures 8 to 11 As shown, the transmission assembly 150 of this embodiment includes a second rotating shaft 154. A drive arm 153 is rotatably connected to the second rotating shaft 154. The drive arm 153 rotates clockwise or counterclockwise around the second rotating shaft 154 to drive the front scraper 130 to switch between a first position and a second position.
[0194] It should be noted that the directions of the drive arm 153's clockwise and counterclockwise rotation around the second axis 154 are opposite. Clockwise rotation of the drive arm 153 around the second axis 154 can refer to either clockwise or counterclockwise rotation. Counterclockwise rotation of the drive arm 153 around the second axis 154 can also refer to either clockwise or counterclockwise rotation. This is not limited in the embodiments of this application. For ease of description, the drive arm 153 in this embodiment is described using clockwise rotation as the example and counterclockwise rotation as the example.
[0195] In this embodiment, the drive arm 153 can perform reciprocating motion around the second rotating shaft 154 in a forward or reverse direction to achieve the switching of the front scraper 130 between the first and second positions.
[0196] Specifically, refer to Figures 8 to 11 As shown, when the drive arm 153 rotates clockwise around the second pivot 154, the end of the drive arm 153 connected to the adapter 131 can be flipped towards the surface to be cleaned. The drive arm 153 can also cause the front scraper 130 to be flipped towards the surface to be cleaned via the adapter 131, so that the front scraper 130 can contact the surface to be cleaned and can be in the first position.
[0197] When the drive arm 153 rotates counterclockwise around the second pivot 154, the end of the drive arm 153 connected to the adapter 131 can deflect away from the surface to be cleaned. The drive arm 153 can cause the front scraper 130 to flip away from the surface to be cleaned through the adapter 131, so that the front scraper 130 can have a gap with the surface to be cleaned and the front scraper 130 contacts the roller brush 120. At this time, the front scraper 130 is in the second position.
[0198] In some examples, the connection between the drive arm 153 and the adapter 131 may be spaced from the first pivot 140. The front scraper 130 may be located on the side of the adapter 131 away from the connection between the drive arm 153 and the adapter 131. The portion of the front scraper 130 away from the first pivot 140 may be used to contact the surface to be cleaned.
[0199] See also some of the possible implementation methods. Figure 10 and Figure 11 As shown, in this embodiment of the application, the first connecting portion 1521 is located on the drive arm 153. The second connecting portion 132 is located on the front scraper 130. One of the first connecting portion 1521 and the second connecting portion 132 is a groove. The other of the first connecting portion 1521 and the second connecting portion 132 is a sliding column. The sliding column slides in the groove so that when the drive arm 153 rotates in the forward or reverse direction, the second connecting portion 132 drives the front scraper 130 to rotate axially about the first rotating shaft 140.
[0200] It should be noted that the drive arm 153 may be provided with a sliding groove, and the front scraper 130 may be provided with a sliding column. Alternatively, the drive arm 153 may be provided with a sliding column, and the front scraper 130 may be provided with a sliding groove. This is not limited in the embodiments of this application. For ease of description, this application uses the example of the drive arm 153 having a sliding groove and the front scraper 130 having a sliding column for description.
[0201] Among them, reference Figures 8 to 11 As shown, when the drive arm 153 rotates clockwise around the second rotating shaft 154, the sliding column can rotate counterclockwise relative to the axial direction of the first rotating shaft 140 through the coordinated movement of the sliding column and the sliding groove. This allows the adapter 131 to rotate counterclockwise, thereby allowing the front scraper 130 to rotate counterclockwise relative to the axial direction of the first rotating shaft 140. The portion of the front scraper 130 away from the first rotating shaft 140 can move away from the roller brush 120. At this time, the front scraper 130 can move towards the first position.
[0202] Continue to refer to Figures 8 to 11As shown, when the drive arm 153 rotates counterclockwise around the second rotating shaft 154, the sliding column can rotate clockwise relative to the axial direction of the first rotating shaft 140 through the coordinated movement of the sliding column and the sliding groove. This allows the adapter 131 to rotate clockwise, thereby allowing the front scraper 130 to rotate clockwise relative to the axial direction of the first rotating shaft 140. The portion of the front scraper 130 away from the first rotating shaft 140 can move towards the roller brush 120. At this time, the front scraper 130 can move towards the second position.
[0203] In some examples, when the drive arm 153 is connected to the power unit 170 via the connecting arm 155, the power unit 170 can drive the connecting arm 155 to rotate forward or backward, so that the drive arm 153 can rotate forward or backward about the axis of the second pivot 154. Specifically, refer to Figures 8 to 11 As shown, when the connecting arm 155 rotates clockwise, the driving arm 153 can rotate counterclockwise around the axis of the second rotating shaft 154, so that the adapter 131 can rotate clockwise, the front scraper 130 can rotate clockwise relative to the axis of the first rotating shaft 140, and the front scraper 130 can reach the second position.
[0204] Continue to refer to Figures 8 to 11 As shown, when the connecting arm 155 rotates counterclockwise, the driving arm 153 can rotate clockwise around the axis of the second rotating shaft 154, so that the adapter 131 can rotate counterclockwise, the front scraper 130 can rotate counterclockwise relative to the axis of the first rotating shaft 140, and the front scraper 130 can reach the first position.
[0205] See also some of the possible implementation methods. Figure 7 As shown, the floor brush body 110 of this embodiment includes a support arm 111 for fixing the roller brush 120. Along the length direction Z of the front scraper 130, the support arm 111 is disposed near the end of the floor brush body 110. A second rotating shaft 154 is disposed on the support arm 111.
[0206] In this embodiment, the support arm 111 can be used to fix the roller brush 120. On the other hand, the transmission assembly 150 can be connected to the support arm 111 via the second rotating shaft 154. The support arm 111 can provide support for the transmission assembly 150. Therefore, the brush body 110 does not need an additional structure for fixing the transmission assembly 150, which helps to reduce the complexity of the brush assembly 100 structure.
[0207] It is easy to understand that since the drive arm 153 is a rigid structure, the drive arm 153 has good strength. Therefore, when the drive arm 153 is set at the end of the floor brush body 110, it can also make the front scraper 130 have good stability during the flipping process, so as to improve the reliability of the front scraper 130 switching between the first position and the second position.
[0208] This application provides a cleaning device, which may include a body and the floor brush assembly 100 in any of the above embodiments.
[0209] The floor brush assembly 100 is connected to the main body. During operation of the cleaning equipment, the user can push the main body to move the floor brush assembly 100 forward or backward.
[0210] The cleaning device provided in this application embodiment has a front scraper 130 that flips relative to the brush body 110 and can switch between a first position and a second position. Therefore, when the front scraper 130 is in the first position, by contacting the surface to be cleaned, it can scrape away water stains generated by the roller brush 120 on the surface as the brush body 110 retracts, reducing the possibility of watermarks remaining on the surface. Furthermore, when the brush body 110 moves to the bottom of a wall or encounters an obstacle, the front scraper 130 can remove dirt from the bottom of the obstacle during its retraction, reducing hard-to-reach areas and improving cleaning effectiveness.
[0211] When the front squeegee 130 is in the second position, it is in contact with the roller brush 120. Therefore, when the roller brush 120 rotates, it can at least clean the surface of the front squeegee 130 facing the roller brush 120 to achieve the self-cleaning function of the front squeegee 130, thus eliminating the need for manual cleaning by the user. Furthermore, the contact between the front squeegee 130 and the roller brush 120, and the relative force between them, ensures that the liquid on the roller brush 120 is evenly distributed, reducing the possibility of excessive liquid content in certain areas and causing water stains on the surface to be cleaned, thereby improving the cleaning effect.
[0212] In particular, after the roller brush 120 has been used and worn for a long time, more water marks will remain on the surface to be cleaned. By having the front scraper 130 contact the roller brush 120 in the second position, the water can be evenly distributed on the roller brush 120.
[0213] In some examples, the cleaning equipment may also include a clean water tank and a wastewater tank. The clean water tank and wastewater tank may be mounted on the floor brush assembly 100 or on the main body. Alternatively, one of the clean water tank and wastewater tank may be mounted on the floor brush assembly 100, and the other may be mounted on the main body. No limitation is made in the embodiments of this application.
[0214] This application provides a cleaning system, which may include a base or a base station. Cleaning equipment may be placed on the base or base station.
[0215] In some examples, the base can be used to clean and dry the roller brush 120 to prevent the roller brush 120 from being damp for a long time, which could lead to odors or bacteria.
[0216] In some examples, the base station may have a charging function. When the cleaning equipment is placed on the base station, it can be charged and automatically have water supplied and drained. The base and the base station can be separate structures, or they can be an integrated structure; this is not limited in the embodiments of this application.
