Description

Technical Field

[0001] This invention relates to the field of surface cleaning technology, and in particular to a floor brush assembly and cleaning device. Background Technology

[0002] Cleaning equipment such as floor scrubbers, electric mops, and robotic vacuum cleaners are widely used in homes and commercial spaces due to their efficient cleaning capabilities.

[0003] Take floor scrubbers as an example. To achieve edge cleaning of areas such as walls and the bottom edges of cabinets, some floor scrubbers have added a mop tray to the roller brush, using this mop tray to clean corners without touching them. However, this mop tray cannot be cleaned in time, resulting in the same dirty mop being used again.

[0004] To address the aforementioned issues, some floor scrubbers have incorporated a self-cleaning mechanism into their brush pads. This mechanism cleans itself during the brush's operation. However, during use, the dirt generated by this self-cleaning process (including wastewater and solid debris) can flow or drip directly onto the floor, potentially causing secondary pollution and resulting in a poor user experience. Summary of the Invention

[0005] To address at least one of the technical problems mentioned in the background art, embodiments of this application provide a floor brush assembly and a cleaning device.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A first aspect of this application provides a floor brush assembly, the floor brush assembly comprising:

[0008] The main body of the floor brush can move along a preset direction on the surface to be cleaned;

[0009] The main cleaning component is located in the main body of the floor brush;

[0010] An auxiliary cleaning component is movable relative to the main body of the floor brush and extends at least partially beyond the main body of the floor brush to perform edge cleaning;

[0011] The self-cleaning component includes an auxiliary suction channel and a scraper. The scraper can contact the auxiliary cleaning component to clean it. The auxiliary suction channel is used to suck away the dirt generated by the scraper while cleaning the auxiliary cleaning component.

[0012] When the auxiliary cleaning component needs self-cleaning, use the scraper to remove dirt from its surface and open the auxiliary suction channel to remove the dirt, reducing or even preventing dirt from falling onto the floor. This method improves the problem of secondary pollution caused by the self-cleaning of the auxiliary cleaning component and enhances the cleaning experience.

[0013] Optionally, the auxiliary cleaning component includes an auxiliary drive component and an auxiliary cleaning element, the auxiliary cleaning element having an initial position relative to the floor brush host, and the scraper contacting the auxiliary cleaning element at the initial position;

[0019] During the cleaning process of the auxiliary cleaning component, the first channel is connected to the second channel. When the scraper is separated from the auxiliary cleaning component, the first channel is separated from the second channel, and the scraper blocks the second channel.

[0020] Optionally, the scraper has a limiting protrusion configured such that when the first channel and the second channel are connected, the limiting protrusion is limited to prevent the scraper from continuing to move.

[0021] Optionally, the scraper moves relative to the main body of the floor brush by rotation. The scraper has a circumferential surface arranged around the rotation center of the scraper. The outlet of the first channel is located on the circumferential surface. When the outlet of the first channel separates from the second channel, the circumferential surface blocks the second channel.

[0022] Optionally, the self-cleaning component includes a scrubbing drive component for driving the scraper movement.

[0023] Optionally, along the preset direction, the self-cleaning component is located between the main suction port and the auxiliary cleaning component.

[0024] Optionally, the scraper is provided with ribs for cleaning the auxiliary cleaning component. The ribs are provided with flow channels communicating with the auxiliary suction port on both sides of the cleaning path.

[0048] To make the technical solution and beneficial effects of the present invention more apparent and understandable, a detailed description is provided below by listing specific embodiments. The accompanying drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly show the details of the local features; unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application pertains.

[0049] The following is combined with Figures 1 to 13 The technical solutions of the embodiments of this application will be introduced.

[0050] This application provides a floor brush assembly 10, which includes a floor brush body 140, a main cleaning assembly 110, an auxiliary cleaning assembly 120, and a self-cleaning assembly 130.

[0051] See Figure 1 The brush body 140 is the supporting structure of the brush assembly 10. For example, the brush body 140 includes a base plate 141, a top plate, and other shell parts.

[0052] The main cleaning component 110 is located on the floor brush body 140. See also... Figure 5 The main cleaning assembly 110 includes a main drive assembly and a main cleaning component 111. In the implementation illustrated in this application, the main cleaning component 111 is a roller brush, and the main drive assembly includes a roller brush motor. During the back-and-forth movement of the floor brush assembly 10 along a preset direction, the roller brush motor drives the roller brush to rotate. The rotating roller brush can not only clean the surface to be cleaned better, but also help to roll the dirt towards the main suction port 142 at the bottom of the floor brush body 140.

[0053] The surface to be cleaned includes surfaces such as floors, carpets, and floorboards. For ease of description, the embodiments of this application will use "floor" instead of "surface to be cleaned".

[0054] The auxiliary cleaning component 120 includes an auxiliary cleaning element 122, such as a mop tray. The auxiliary cleaning component 120 is movable relative to the brush body 140 and extends at least partially beyond the brush body 140 for edge cleaning. This movement includes at least lifting and lowering motion. When edge cleaning is required, the mop tray lowers to contact the surface to be cleaned. When edge cleaning is not required, the mop tray is raised away from the surface to be cleaned.

[0055] See Figure 1The horizontal direction refers to the axial direction of the roller brush. Along the axial direction of the roller brush, its axial width is approximately the same as the horizontal width of the brush body 140. That is, the cleaning area of ​​the roller brush on the surface to be cleaned is designated as the first cleaning area. The horizontal width of the first cleaning area is approximately equal to the horizontal width of the brush body 140. The cleaning area of ​​the mop pad on the surface to be cleaned is designated as the second cleaning area. The second cleaning area is at least partially located outside the first cleaning area in the horizontal direction. Therefore, the auxiliary cleaning component 122 can clean the edge areas that the main cleaning component 111 cannot reach, achieving zero-edge cleaning.

[0056] The self-cleaning component 130 includes an auxiliary suction channel 133 and a scrubbing component, such as a scraper 131 or a scraper strip. For ease of description, in this embodiment, the scrubbing component is described using a scraper 131 as an example.

[0057] The scraper 131 can contact the auxiliary cleaning component 120 to clean the auxiliary cleaning component 120, and the auxiliary suction channel 133 is used to suck away the dirt generated by the scraper 131 in cleaning the auxiliary cleaning component 120.

[0058] When the auxiliary cleaning component 120 needs self-cleaning, use the scraper 131 to scrape off the dirt on the surface of the auxiliary cleaning component 122, and open the auxiliary suction channel 133 to suck up the dirt, reducing or even preventing dirt from falling onto the ground. This method improves the problem of secondary pollution caused by the self-cleaning of the auxiliary cleaning component 122, and enhances the cleaning experience.

[0059] In some alternative embodiments, the auxiliary cleaning assembly 120 includes an auxiliary drive assembly 121 and an auxiliary cleaning element 122, the auxiliary cleaning element 122 having an initial position relative to the brush host (see [link]). Figure 1 and Figure 2 The auxiliary cleaning component 122 referred to in section A, and Figure 3 As shown), the scraper 131 contacts the auxiliary cleaning component 122 in the initial position. The auxiliary drive assembly 121 is at least used to drive the auxiliary cleaning component 122 away from the initial position for edge cleaning.

[0060] Under the action of the auxiliary drive assembly 121, the auxiliary cleaning component 122 moves away from the cleaning position and toward the cleaning position. The auxiliary cleaning component 122 performs edge cleaning at the cleaning position. The scraper 131 separates from the auxiliary cleaning component 122 before it leaves its initial position, thus avoiding interference with the movement of the auxiliary cleaning component 122.

[0061] Figure 1 and Figure 2 The auxiliary cleaning component 122 mentioned in section B and Figure 4 All auxiliary cleaning components 122 shown are in the cleaning position.

[0062] In the prior art, the auxiliary cleaning component 122 performs real-time self-cleaning during the edge cleaning process. This self-cleaning method has the following problems: if the auxiliary cleaning component 122 swings outward from the side of the main cleaning component 111 at the cleaning position by a large distance, the dirt generated by the real-time self-cleaning of the auxiliary cleaning component 122 is difficult to be cleaned by the main cleaning component 111 when it passes by.

[0063] In this application, the auxiliary cleaning component 122 does not perform edge cleaning in its initial position, but it can contact the scraper 131 to achieve self-cleaning. When in the cleaning position, the auxiliary cleaning component 122 can perform edge cleaning, but does not perform self-cleaning. This intermittent self-cleaning method, where the auxiliary cleaning component 122 is not in operation, ensures that since the auxiliary cleaning component 122 is almost entirely behind the main cleaning component 111 in its initial position, any dirt generated during self-cleaning that falls to the ground will primarily fall within the cleaning area of ​​the main cleaning component 111 and be easily cleaned by it.

[0064] See Figure 9 The scraper 131 has a structure such as protrusions or ribs 1312 on the side (i.e., top) that is in contact with the auxiliary cleaning component 122 to facilitate scraping the garbage.

[0065] In some alternative embodiments, the scraper 131 is movable relative to the brush body 140 to contact or separate from the auxiliary cleaning element 122. See also Figure 1 and Figure 2 When self-cleaning is required, the auxiliary cleaning component 122A and the central scraper 131A are in their initial positions, and the scraper 131A moves to a position where it contacts the auxiliary cleaning component 122A. (See also...) Figure 1 and Figure 2 When self-cleaning is not required, the scraper 131B and the auxiliary cleaning component 122B are separated. The movement of the scraper 131 and the auxiliary cleaning component 122B are relatively independent, allowing for more flexible selection of the scraper 131's position and the timing and duration of self-cleaning.

[0066] See Figure 10 and Figure 11 In some alternative embodiments, the auxiliary suction channel 133 is at least partially located on the scraper 131, and the inlet of the auxiliary suction channel 133 is the auxiliary suction port 1333 located on the scraper 131 (i.e., the inlet of the first channel 1331 mentioned below). In this way, the auxiliary suction port 1333 can be closer to the contact position between the scraper 131 and the auxiliary cleaning component 122, which is beneficial for timely removal of dirt generated during the self-cleaning process.

[0067] The auxiliary suction channel 133 is at least partially located on the scraper 131, including: see Figure 11Holes are made in the scraper 131 to form at least part of the auxiliary suction channel 133, so that the scraper 131 and at least part of the auxiliary suction channel 133 form an integral structure, which makes the structure more compact.

[0068] In some other implementations not shown in this application, the auxiliary suction channel 133 provided on the scraper 131 can also be a suction pipe, with the scraper 131 serving as the mounting carrier for the suction pipe.

[0069] See Figure 10 In some alternative embodiments, the scraper 131 is provided with a rib 1312 for cleaning the auxiliary cleaning assembly 120. The rib 1312 is provided with a flow channel 1313 communicating with the auxiliary suction port 1333 on both sides of the cleaning path. The opening 1315 of the flow channel 1313 faces the auxiliary cleaning assembly to receive dirt falling from the auxiliary cleaning assembly 120.

[0070] The flow channels 1313(A) and 1313(B) on both sides of the rib 1312 are connected and both are connected to the auxiliary suction channel 133. Assume that flow channel 1313(A) is located on the front side of the self-cleaning path (corresponding to the side of the auxiliary cleaning component 122 that has not been scraped), and flow channel 1313(B) is located on the rear side of the self-cleaning path (corresponding to the other side of the auxiliary cleaning component 122 that has been scraped). During the friction of the scraper 131 against the auxiliary cleaning component 122, dirt scraped off by the rib 1312 can fall into flow channel 1313(A), while dirt may also fall from the rear side of the rib 1312 from the auxiliary cleaning component 122, and this dirt is collected by flow channel 1313(B). Therefore, the two flow channels 1313 on both sides of the rib 1312 can minimize dirt contamination of the ground.

[0071] During the self-cleaning process, the flow channels 1313 on both sides of the rib 1312 can better match the forward or reverse rotation of the auxiliary cleaning component 122, so that the flow channels 1313 on the corresponding side can effectively collect dirt regardless of whether the auxiliary cleaning component 122 rotates forward or reverse.

[0072] For example, if the flow channels 1313(A) and 1313(B) on both sides of the rib 1312 are considered as a whole flow channel, the rib 1312 can also be regarded as being located at approximately the middle position of the whole flow channel, and the length direction of the rib 1312 is approximately parallel to the length direction of the scraper 131.

[0073] In some alternative embodiments, a filter structure 136 is provided within the flow channel 1313. The filter structure 136 is configured to filter dirt flowing toward the auxiliary suction port 1333. The filter structure 136 can filter dirt such as hair, fibers, and paper scraps, reducing or even preventing such dirt from clogging the auxiliary suction port 1333 or the auxiliary suction channel 133.

[0074] See Figure 10In some alternative embodiments, the filter structure 136 is a plurality of protrusions 1361 spaced apart within the flow channel 1313. Figure 10 Two protrusions 1361 are provided on each side of the two flow channels 1313 near the auxiliary suction port 1333. Dirt that is not easily clogged flows to the auxiliary suction port 1333 through the gap between the two protrusions 1361, while large particles or hair are intercepted and filtered in the upstream space of the flow channel 1313 and cannot flow to the auxiliary suction port 1333. The scraper 131 integrates the ribs 1312, the flow channel 1313 and multiple protrusions 1361. This filter structure 136 is integrally formed with the flow channel 1313, and the structure is simple.

[0075] In some alternative embodiments, the ribs 1312 are staggered from the auxiliary suction port 1333. Figure 10 In the middle, the rib 1312 will be offset from one side of the auxiliary suction port 1333, leaving more space near the auxiliary suction port 1333, reducing or even avoiding clogging of the auxiliary suction port 1333.

[0076] In some alternative embodiments, the auxiliary suction port 1333 and the auxiliary cleaning member 122 are spaced apart by a distance G (see [reference]) along a direction parallel to the bottom surface of the auxiliary cleaning member 122. Figure 12 ).

[0077] Taking the wiping cloth tray as an example, the auxiliary cleaning component 122 has a scraper 131 and a flow channel 1313 arranged approximately along the radial direction of the auxiliary cleaning component 122. The auxiliary suction port 1333 communicates with the flow channel 1313, but is not located directly below the wiping cloth tray. See [link to relevant documentation]. Figure 12 The auxiliary suction port 1333 and the cloth tray are spaced apart in the horizontal direction (parallel to the bottom surface of the cloth tray). The dirt that falls from the auxiliary cleaning component 122 is temporarily collected in the flow channel 1313 and flows towards the auxiliary suction port 1333 under the action of negative pressure suction, reducing the risk of dirt being sucked into the auxiliary suction port 1333 without filtration, and further reducing the risk of the auxiliary suction channel 133 being blocked.

[0078] See Figure 2 In some optional embodiments, the floor brush assembly 10 further includes a main suction channel 150, and the floor brush body 140 also has a main suction port 142 communicating with the main suction channel 150. Dirt generated during the cleaning process of the main cleaning assembly 110 enters the main suction channel 150 through the main suction port 142. The auxiliary suction channel 133 is communicating with the main suction channel 150.

[0079] During the cleaning process, dirt generated by the main cleaning component 110 enters the main suction channel 150 through the main suction port 142. The negative pressure source of the main suction channel 150 and the auxiliary suction channel 133 can be the same, such as the suction motor 50 of the cleaning equipment. The dirt sucked up by the main suction channel 150 and the auxiliary suction channel 133 can also be collected by the wastewater tank 40.

[0080] Since the auxiliary suction channel 133 is connected to the main suction channel 150, the dirt in the auxiliary suction channel 133 enters the sewage tank 40 through the main suction channel 150. This method can reduce the length of the auxiliary suction channel 133 and save space.

[0081] See Figures 5 to 7 In some optional embodiments, the auxiliary suction channel 133 includes a first channel 1331 and a second channel 1332. The first channel 1331 is located on the scraper 131, and the inlet of the first channel 1331 is the auxiliary suction port 1333. The second channel 1332 is connected to the outlet 1334 of the first channel 1331 and the main suction channel 150, respectively. The first channel 1331 moves synchronously with the scraper 131. During the cleaning process of the auxiliary cleaning component 120 (specifically, the auxiliary cleaning element 122), the scraper 131 connects the first channel 1331 and the second channel 1332. When the scraper 131 separates from the auxiliary cleaning element 122, the first channel 1331 separates from the second channel 1332, and the scraper 131 blocks the second channel 1332.

[0082] The second channel 1332 is fixed relative to the scraper 131. When edge cleaning is required, the scraper 131 is first moved to a position away from the auxiliary cleaning component 122 to avoid it. Then, the auxiliary cleaning component 122 is activated, causing it to leave its initial position and move towards the cleaning position. Since the first channel 1331 and the second channel 1332 separate when the scraper 131 leaves the auxiliary cleaning component 122, and the second channel 1332 is blocked, the auxiliary suction channel 133 closes, and self-cleaning stops. Closing the auxiliary suction channel 133 also helps ensure that the main suction channel 150 obtains greater suction power. The movement of the scraper 131 not only enables the start and stop of self-cleaning but also controls the opening and closing of the auxiliary suction channel 133, allowing it to be opened and closed as needed. The auxiliary suction channel 133 does not require a separate control valve for on / off control, resulting in a simpler and more compact structure.

[0083] Once the edge cleaning is complete, or if the auxiliary cleaning component 122 is dirty and self-cleaning is required, control the scraper 131 to return from the cleaning position to the initial position, and then move the scraper 131 to the position where it contacts the auxiliary cleaning component 122. The first channel 1331 moves with the scraper 131 to the position where it connects with and is guided to the second channel 1332, the auxiliary suction channel 133 opens, and self-cleaning begins.

[0084] Figure 2 , Figures 5 to 8 The connector 135 of the second channel 1332 is shown as an example. The second channel 1332 may also include a pipe connecting the connector 135 and the main suction channel 150.

[0085] In some alternative embodiments, the scraper 131 has a limiting protrusion 1314, which is configured such that when the first channel 1331 and the second channel 1332 are connected, the limiting protrusion 1314 is limited to prevent the scraper 131 from continuing to move.

[0086] See Figure 8 The connector 135 of the second channel 1332 can be mounted on the bracket 134. When the scraper 131 rotates from a non-self-cleaning state to a self-cleaning state, the limiting protrusion 1314 rotates towards the bracket 134, and when the scraper 131 reaches the working position, see [reference needed]. Figure 6 The limiting protrusion 1314 abuts against the bracket 134, meaning the bracket 134 limits the limiting protrusion 1314, preventing the scraper 131 from continuing to move, thus avoiding excessive rotation of the scraper 131 and ensuring better alignment and conduction of the first channel 1331 and the second channel 1332. In addition to the bracket 134, other fixing components can also be provided to limit the limiting protrusion 1314.

[0087] Combination Figure 1 , Figure 2 and Figures 5 to 7 In some optional embodiments, the scraper 131 moves relative to the brush body 140 in a rotating manner. The scraper 131 has a circumferential surface 1311 arranged around the rotation center of the scraper 131. The outlet 1334 of the first channel 1331 is located on the circumferential surface 1311. When the outlet 1334 of the first channel 1331 is separated from the second channel 1332, the circumferential surface 1311 blocks the second channel 1332.

[0088] By setting the outlet 1334 of the first channel 1331 on the circumferential surface 1311, and then using rotation to achieve the connection or disconnection of the first channel 1331 and the second channel 1332, the structure is simpler. When it is necessary to connect the first channel 1331 and the second channel 1332, based on... Figure 7 The motor rotates forward to control the scraper 131 to rotate counterclockwise until the scraper 131 moves to... Figure 6 At the position shown, the second channel 1332 is connected to the first channel 1331. When it is necessary to close the auxiliary suction channel 133, the motor reverses to control the scraper 131 to rotate clockwise until the scraper 131 moves to... Figure 7 At the position shown, the first channel 1331 and the second channel 1332 are separated.

[0089] Figure 6 A schematic diagram of the structure in which the first channel 1331 and the second channel 1332 are connected and conductive during the self-cleaning process of the auxiliary cleaning component 122. Figure 7 This is a schematic diagram of the structure when the first channel 1331 and the second channel 1332 are separated, before self-cleaning is performed. Figure 7It can be seen that the exit 1334 of the first channel 1331 is staggered from that of the second channel 1332.

[0090] See Figure 8 The side of the connector 135 facing the circumferential surface 1311 is an arc surface 1323 to ensure the reliability of the circumferential surface 1311 in blocking the entrance of the second channel 1332 in the non-self-cleaning state. The aforementioned limiting protrusion 1314 is located on the circumferential surface 1311 of the scraper 131. When the scraper 131 rotates from the non-self-cleaning state to the self-cleaning state, the limiting protrusion 1314 rotates towards the bracket 134, and when the scraper 131 reaches the working position, see [reference needed]. Figure 6 The limiting protrusion 1314 abuts against the bracket 134 to prevent the scraper 131 from rotating excessively.

[0091] In some alternative embodiments, the self-cleaning component 130 includes a scrubbing drive component 132 for driving the scraper 131 to move.

[0092] The scrubbing drive assembly 132 includes a servo motor or electric motor and a scrubbing transmission assembly, etc. The scrubbing transmission assembly can be a gear transmission assembly, a worm gear transmission assembly, etc.

[0093] The aforementioned bracket 134 can be connected to the housing 1321 of the scrubbing drive assembly 132, and the motor, scrubbing transmission assembly, etc. are located inside the housing 1321.

[0094] See Figure 2 In some optional embodiments, the self-cleaning component 130 is located between the main suction port 142 and the auxiliary cleaning component 122 along a preset direction. This facilitates self-cleaning and shortens the length of the auxiliary suction channel 133, reducing suction resistance.

[0095] See Figure 3 In some optional embodiments, when the scraper 131 is in the initial position, the orthographic projection of the auxiliary cleaning component 122 onto the reference plane M is located within the orthographic projection range of the brush body 140 onto the reference plane M, wherein the reference plane M is parallel to the bottom surface of the brush body 140. When edge cleaning is not required, the auxiliary cleaning component 122 retracts and can be shielded by the brush body 140, which protects the auxiliary cleaning component 122 and reduces the risk of damage caused by the auxiliary cleaning component 122 protruding from the brush body 140 and colliding with obstacles.

[0096] For example, when edge cleaning is required, the auxiliary cleaning component 122 first descends from its initial position and then swings outward toward the side of the roller brush to reach the cleaning position. When edge cleaning is completed or self-cleaning is required, the auxiliary cleaning component 122 can first retract inward and then rise back to its initial position. Here, the lifting, swinging, retraction, and rotation (including rotation during ground cleaning and self-cleaning) of the auxiliary cleaning component 122 can all be achieved by the auxiliary drive component 121. The auxiliary drive component 121 can adopt existing designs, such as those disclosed in CN121667586A, which will not be described in detail in this application embodiment. The switching of the auxiliary cleaning component 122 between the initial position and the cleaning position can also be achieved solely through lifting motion, and is not limited to the methods listed in this application embodiment.

[0097] See Figure 13 The main body of the floor brush 140 has an avoidance opening 143 on its side, through which the auxiliary cleaning component 122 swings out or retracts.

[0098] Figures 1 to 4 ,as well as Figure 13 Although the auxiliary cleaning component 122 is shown exemplarily on the right side of the floor brush body 140, it is not limited thereto.

[0099] To improve the cleaning effect on the edge and during the self-cleaning process, a water supply pipe can be provided for the auxiliary cleaning component 122. See [link / reference] Figure 13 The water supply pipeline includes a water outlet pipe 160 located above the auxiliary cleaning component 122 and capable of moving with the auxiliary cleaning component 122. The outlet of the water outlet pipe 160 is located above the auxiliary cleaning component 122 so that water can drip onto the cloth of the auxiliary cleaning component 122. The water in the water outlet pipe 160 can come from the clean water tank 20 of the cleaning equipment.

[0100] For example, the water outlet pipe 160 is installed at the bottom of the housing 1321 of the swing arm 1211 of the auxiliary drive assembly 121. When the drive source of the drive assembly (usually a motor) drives the swing arm 1211 to swing out or retract, it always ensures that the outlet of the water outlet pipe 160 is located above the auxiliary cleaning component 122.

[0101] See Figure 14 This application also provides a cleaning device, which includes a suction motor 50 and a floor brush assembly 10 as described in any of the foregoing embodiments. The suction motor 50 can provide suction force for the auxiliary suction channel 133.

[0102] The cleaning equipment has the same technical effect as the aforementioned floor brush assembly 10, and will not be described again.

[0103] The self-cleaning mentioned in this application is different from the self-cleaning of the cleaning device on the base assembly; these two self-cleaning processes are not necessarily related. Normally, when the cleaning device is performing a complete cleaning operation or requires maintenance, it can be placed on the base assembly, which charges the device and allows for self-cleaning of both the main cleaning component 111 and the auxiliary cleaning component 122. The aforementioned self-cleaning of the auxiliary cleaning component 122 occurs when the cleaning device is separated from the base assembly, utilizing the device's own structure for self-cleaning. Furthermore, the self-cleaning process of the auxiliary cleaning component 122 using the scraper 131 has almost no impact on the operation of the main cleaning component 111; that is, the main cleaning component 111 can remain clean while the scraper 131 scrapes the auxiliary cleaning component 122.

[0104] The cleaning equipment in this application includes, but is not limited to, floor scrubbers, mop-washer combos, and electric mops.

[0105] Taking a floor scrubber as an example, one end of the machine body 30 is rotatably connected to the main body 140 of the floor brush, and the other end of the machine body 30 is equipped with a handle 31. During the cleaning process, the operator or user can hold the handle 31 and swing the machine body 30 to move the floor brush assembly forward, causing the roller brush to rub against the surface to be cleaned, thereby cleaning the surface. Surfaces to be cleaned include floors, carpets, walls, tabletops, etc. For ease of description, the floor is used as an example to describe the surface to be cleaned.

[0106] In some alternative implementations, the cleaning equipment may also include a clean water tank 20, which can provide water to the main cleaning component 111, auxiliary cleaning component 122, etc.

[0107] In some alternative implementations, the cleaning equipment may also include a wastewater tank 40 for collecting dirt from the cleaning process, which is generally a solid-liquid mixture.

[0108] In some alternative implementations, the cleaning device may also include a suction motor 50. Typically, the floor brush body 140 has a main suction port 142, and a main suction channel 150 exists between the main suction port 142 and the suction motor 50. The negative pressure suction generated by the high-speed operation of the suction motor 50 can penetrate the entire main suction channel 150. Under the action of negative pressure suction, dirt cleaned by the main cleaning component 111 from the surface to be cleaned can enter the wastewater tank 40 through the main suction port 142 and the main suction channel 150. In conjunction with the foregoing description, when the auxiliary suction channel 133 is open, dirt generated by self-cleaning sequentially enters the wastewater tank 40 through the auxiliary suction channel 133 and the main suction channel 150.

[0109] Other structural features of the cleaning equipment may be the same as those of existing cleaning equipment and will not be described again.
