Description

[0001] This application claims priority to PCT application No. PCT / CN2024 / 084561, filed on March 28, 2024, entitled “Underwater cleaning robot and filter structure and transmission structure thereof”, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the technical field of cleaning devices, in particular to a cleaning roller brush and an underwater cleaning robot. BACKGROUND

[0003] An underwater cleaning robot is a cleaning robot for underwater cleaning needs, which can complete the cleaning of the underwater part of the structure and the filtering of the water body. Most of the existing underwater cleaning robots clean pollutants through a rotatable roller brush to make the pollutants separate from the bottom and the wall of the pool. However, the bristles of the existing roller brush are mostly arranged in a direction parallel to the rotation axis of the roller brush. This shape of the roller brush easily causes the pollutants brushed off from the surface of the pool to drift horizontally between the gaps between adjacent two rows of bristles, so that part of the pollutants near the roller brush during the brushing process easily spread and drift away, which are difficult to be sucked and collected by the water suction port at the bottom of the underwater cleaning robot. SUMMARY

[0004] Therefore, the present application provides a cleaning roller brush to at least partially solve the above problems.

[0005] The present application provides a cleaning roller brush, comprising: a brush wheel, a brush body, the brush body is sleeved outside the brush wheel, and a plurality of rows of bristles arranged along the circumferential direction of the brush wheel are arranged on the brush body; along the axis direction of the brush wheel, each row of bristles comprises a water collecting section and an extension section, and the end of the water collecting section intersects or is adjacent to the extension section; when the brush body is separated from the brush wheel and is in an unfolded state, the included angle between the water collecting section and the extension section of the same row is obtuse; when the brush body is installed on the brush wheel, the extension section is parallel to the axis of the brush wheel.

[0006] In some optional embodiments, the number of the brush bodies is two, and the two brush bodies are coaxial and symmetrically arranged.

[0007] In some optional embodiments, the number of the brush wheels is two, and the two brush wheels are coaxially arranged, and each brush body is sleeved on one brush wheel; in each brush body, at least one row of bristles near the end of the other brush body is provided with an elongated portion; in the two brush bodies, the projection of the elongated portion on the axis of the brush wheel on one brush body intersects the projection of the elongated portion on the axis of the brush wheel on the other brush body.

[0008] In some alternative embodiments, along the axis, the elongated portion includes a first end connected to the brush tooth body and a second end opposite to the first end; the brushing side edge of the elongated portion is flush with the brush tooth body, and the width of the elongated portion gradually decreases from the first end to the second end.

[0009] In some alternative embodiments, the number of water collection segments and / or extension segments in each row of brush teeth is multiple, and the water collection segments and extension segments are arranged alternately.

[0010] In some alternative embodiments, the length of the water collection section projected onto the axis of the brush wheel is greater than the length of the extension section projected onto the axis.

[0011] In some alternative embodiments, the brush wheel and the brush body are detachably connected.

[0012] In some optional embodiments, both the water collection section and the extension section include a plurality of sub-teeth, with a gap between every two adjacent sub-teeth in each row, and the gaps between every two adjacent rows of sub-teeth are staggered.

[0013] This application also provides an underwater cleaning robot, including a first roller brush, which is the cleaning roller brush in any of the above embodiments.

[0014] In some optional embodiments, the underwater cleaning robot further includes a second roller brush, with the first roller brush and the second roller brush respectively disposed on the front and rear sides of the underwater cleaning robot.

[0015] In this embodiment, the cleaning roller brush includes a brush wheel and a brush body, with the brush body fitted over the brush wheel. The brush body has multiple rows of brush teeth arranged circumferentially along the brush wheel. Along the axis of the brush wheel, each row of brush teeth includes a water-collecting section and an extension section, with the end of the water-collecting section intersecting or adjacent to the extension section, facilitating the extension section to move water or contaminants to the water-collecting section. When the brush body is detached from the brush wheel and in an unfolded state, the angle between the water-collecting section and the extension section in the same row is an obtuse angle. When the brush body is mounted on the brush wheel, the extension section is parallel to the axis of the brush wheel, allowing the water-collecting section to form an angle with the axis of the brush wheel. This prevents the water-collecting section from being perpendicular to the forward direction of the cleaning roller brush, reducing the impact of the water-collecting section on the water flow and contaminants, and facilitating the water-collecting section to guide the movement of water and contaminants. This allows the cleaning roller brush to effectively guide the movement of water or contaminants, preventing contaminants from spreading and drifting away from the vicinity of the cleaning roller brush.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] like Figure 1 As shown, this application embodiment provides a cleaning roller brush 100, including: a brush wheel 110 and a brush body 120, with the brush body 120 sleeved outside the brush wheel 110.

[0033] The brush body 120 is provided with multiple rows of brush teeth 121 arranged circumferentially along the brush wheel 110. The brush teeth 121 can be made of flexible materials such as rubber or plastic to improve the cleaning ability of the brush body 120.

[0034] Along the axial direction of the brush wheel 110, each row of brush teeth 121 includes a water collection section 123 and an extension section 124, and the end of the water collection section 123 intersects or is adjacent to the extension section 124. Exemplarily, the end of the water collection section 123 may intersect with the end of the extension section 124, or there may be a certain gap between the end of the water collection section 123 and the end of the extension section 124, such that the end of the water collection section 123 is adjacent to the end of the extension section 124. The axis of the brush wheel 110 is the axis of rotation when the brush wheel 110 rotates; in this embodiment, the axis of rotation of the brush wheel 110 is simply referred to as the axis.

[0035] Figure 1 In this configuration, the x-axis is parallel to the axis of brush wheel 110, and the y-axis is perpendicular to the x-axis. For example... Figure 2 As shown, when the brush body 120 detaches from the brush wheel 110 and unfolds around the axis of the brush wheel 110, in the unfolded state on the plane defined by the x-axis and y-axis, the angle between the concurrent water collection section 123 and the extension section 124 is an obtuse angle. This obtuse angle can be a positive angle, that is, an obtuse angle formed by rotating the extension section 124 counterclockwise relative to the water collection section 123 (see...). Figure 2 The angle β shown can also be a negative angle, i.e., an obtuse angle formed by rotating the extension 124 clockwise relative to the water collection section 123. When the brush body 120 is mounted on the brush wheel 110, the extension 124 is parallel to the axis of the brush wheel 110, and the water collection section 123 spirals around the axis of the brush wheel 110.

[0036] It should be understood that the extension segment 124 being parallel to the axis of the brush wheel 110 specifically means that the extension segment 124 extends substantially along the axis of the brush wheel 110 and is approximately parallel to the axis. As long as the angle between the extension segment 124 and the axis of the brush wheel 110 is within ±10°, it falls within the range of the extension segment 124 being approximately parallel to the axis of the brush wheel 110 protected by the embodiments of this application.

[0037] In this embodiment, the cleaning roller brush 100 includes a brush wheel 110 and a brush body 120, with the brush body 120 sleeved outside the brush wheel 110. The brush body 120 is provided with multiple rows of brush teeth 121 arranged circumferentially along the brush wheel 110; along the axial direction of the brush wheel 110, each row of brush teeth 121 includes a water collection section 123 and an extension section 124, and the end of the water collection section 123 intersects or is adjacent to the extension section 124, which facilitates the extension section 124 to move water or contaminants to the water collection section 123. When the brush body 120 is detached from the brush wheel 110 and in the unfolded state, the angle between the water collection section 123 and the extension section 124 is an obtuse angle. When the brush body 120 is installed on the brush wheel 110, the extension section 124 is parallel to the axis of the brush wheel 110, so that the water collection section 123 can form an angle with the axis of the brush wheel 110. This avoids the water collection section 123 being perpendicular to the forward direction of the cleaning roller brush 100, reduces the impact of the water collection section 123 on the water flow and contaminants, and facilitates the water collection section 123 to guide the movement of water flow and contaminants. This allows the cleaning roller brush 100 to effectively guide the movement direction of water flow or contaminants, preventing contaminants from spreading away from the vicinity of the cleaning roller brush 100. In addition, the bending combination design of the extension section 124 and the water collection section 123 can add a bending part to the flow channel formed by every two rows of brush teeth 121, preventing the pollutants washed off from escaping directly from the straight flow channel along the water flow, further slowing down the escape speed of the pollutants, and allowing time for the underwater cleaning equipment equipped with the above-mentioned cleaning roller brush 100 to collect the pollutants.

[0038] like Figure 3 and Figure 4 As shown, in some optional embodiments, the number of brush bodies 120 is two segments, which are coaxial and symmetrically arranged. When the two brush bodies 120 are coaxial and symmetrically arranged, the water collection segments 123 on the same row of the two brush bodies 120 are connected relative to each other to form a V-shaped angle. When the cleaning roller brush 100 rotates to clean, the water collection segments on both sides of the brush body guide the contaminants towards the center of the entire roller brush, reducing the amount of escaped contaminants. Furthermore, with the rolling motion, the contaminants accumulated in the main body of the roller brush can be pushed towards the rear of the entire roller brush through the V-shaped angle, so that the contaminants are close to the bottom of the underwater cleaning equipment, making it easier for the contaminants to be sucked in and collected by the underwater cleaning equipment, thus improving the collection efficiency of contaminants.

[0039] For example, such as Figure 3 As shown, according to Figure 3 In terms of orientation, water collection sections 123 are arranged at the right end of the left brush body 120 and the left end of the right brush body. When the two brush bodies 120 are coaxially and symmetrically assembled close to each other, the rows of brush teeth on the two brush bodies 120 are connected and symmetrical about the vertical symmetry plane 130 perpendicular to the paper. At this time, the water collection sections 123 of each row on the two brush bodies 120 can form a V-shaped angle.

[0040] In another example, extensions 124 are arranged at the right end of the left brush body 120 and the left end of the right brush body. In this case, when the two brush bodies 120 are coaxially and symmetrically assembled close to each other, the rows of brush teeth on the two brush bodies 120 are adjacent and symmetrical about the plane of symmetry 130. At this time, a V-shaped angle is formed between the extensions of the water collection sections 123 of the two brush bodies 120. The extensions 124 at the ends of the two brush bodies 120 that are close to each other are sandwiched in the middle area by the two water collection sections 123 forming the above-mentioned V-shaped angle. The four brush teeth as a whole form an isosceles slope. When the cleaning roller brush 100 rotates to clean, the water collection sections of the two brush bodies 120 guide the contaminants to the middle of the entire roller brush and accumulate in the middle extension section 124 area, so that a buffer enclosure is formed in the middle of the cleaning roller brush 100, which can temporarily accumulate and retain more contaminants near the cleaning roller brush 100.

[0041] Those skilled in the art will understand that the number of water collection sections 123 and extension sections 124 on the brush body 120 is not limited to one. As long as the length of each water collection section 123 in each row of brush teeth is set to ensure the guiding effect of the water collection section 123, it is acceptable.

[0042] In some alternative embodiments, each row of brush teeth 121 has multiple water collection sections 123 and / or extension sections 124, and the water collection sections 123 and extension sections 124 are arranged alternately, such that the cleaning roller brush 100 is arranged in axial segments with water collection sections 123 having a guiding function.

[0043] For example, each row of brush teeth 121 of the brush body 120 includes a water collection section 123 and two extension sections 124, with the water collection section 123 located between the two extension sections 124. When there are two brush bodies 120, the extension sections 124 of the two brush bodies 120 are adjacent. Alternatively, each row of brush teeth 121 of the brush body 120 includes two water collection sections 123 and one extension section 124. When there are two brush bodies 120, the water collection sections 123 of the two brush bodies 120 are adjacent. Alternatively, each row of brush teeth 121 of the brush body 120 may also include at least two water collection sections 123 and at least two extension sections 124. In the case where the water collection sections 123 and extension sections 124 are arranged alternately, at least two inclined water collection sections 123 are intermittently arranged on both the left and right sides of the cleaning roller brush 100.

[0044] In this embodiment, each row of brush teeth 121 on the brush body 120 has multiple water collection sections 123 and / or extension sections 124, and the water collection sections 123 and extension sections 124 are arranged alternately. This allows for a more flexible arrangement of the water collection sections 123 and extension sections 124, facilitating the guidance of water flow and contaminant movement in stages and segments through the combination of water collection sections 123 and extension sections 124. By arranging multiple turning sections on each row of brush tooth channels, the flow rate of water within the brush teeth is buffered, preventing contaminants from overflowing from the brush tooth channels during the drainage process.

[0045] In some alternative embodiments, the length of the water collection section 123 projected onto the axis of the brush wheel 110 is greater than the length of the extension section 124 projected onto the axis of the brush wheel 110.

[0046] It should be noted that when there are multiple water collection sections 123 and / or extension sections 124 in each row of brush teeth 121, the length of the water collection section 123 projected on the axis of the brush wheel 110 is greater than the length of the extension section 124 projected on the axis of the brush wheel 110. This can be understood as the total length of the water collection section 123 projected on the axis of the brush wheel 110 being greater than the total length of the extension section 124 projected on the axis of the brush wheel 110.

[0047] In this embodiment, by setting the length of the water collection section 123 projected on the axis of the brush wheel 110 to be greater than the length of the extension section 124 projected on the axis of the brush wheel 110, the water collection section 123 can have a larger range in the axial direction of the brush wheel 110 than the extension section 124, so as to improve the effect of the cleaning roller brush 100 in guiding water flow and pollutants by using the water collection section 123.

[0048] like Figure 1 As shown, in some optional embodiments, both the water collection section 123 and the extension section 124 include a plurality of sub-teeth 125. There is a gap 126 between every two adjacent sub-teeth 125 in each row of sub-teeth 125. The gaps 126 between every two adjacent rows of sub-teeth 125 are staggered, that is, the orthographic projection of the gap 126 of one row of sub-teeth 125 on the other row of sub-teeth 125 does not intersect with the gap 126 of the other row of sub-teeth 125.

[0049] In this embodiment, both the water collection section 123 and the extension section 124 of the brush teeth 121 include multiple sub-teeth 125, which can enhance the deformation capability of the brush body 120. This allows multiple sub-teeth 125 on different parts of the brush teeth 121 to scrub the surface of the target with different postures and angles when rubbing the target, thus optimizing the cleaning effect of the cleaning roller brush 100. On this basis, the gaps 126 between adjacent rows of sub-teeth 125 are staggered, so that when a row of sub-teeth 125 fails to clean a certain area of ​​dirt due to the gaps 126, at least one row of adjacent sub-teeth 125 can clean that area of ​​dirt, avoiding dirt leakage caused by the gaps 126 between the sub-teeth 125.

[0050] like Figure 4 , Figure 5 As shown, in some optional embodiments, there are two brush wheels 110, which are coaxially arranged, with each brush body 120 respectively fitted onto one brush wheel 110, so that the two brush wheels 110 can be driven to rotate independently. Figure 5As shown, in each brush body 120, at least one row of brush teeth 121 has an extension 1211 at the end near the other brush body 120. In the two brush bodies 120, the projection of the extension 1211 on the axis of the brush wheel 110 on one brush body 120 intersects with the projection of the extension 1211 on the axis of the other brush body 120.

[0051] When the two brush segments 120 of the cleaning roller brush 100 are respectively mounted on two independently installed brush wheels 110, gaps will exist at the ends of the two brush segments 120 that are close to each other due to the gap between the brush wheels 110. The presence of these gaps will cause the middle seam of the cleaning roller brush 100 to lack cleaning ability, thereby affecting the cleaning effect of the cleaning roller brush 100. In this embodiment, each brush segment 120 has an extension 1211 at the end of at least one row of brush teeth 121 that is close to the other brush segment 120. Furthermore, the projection of the extension 1211 on the axis of one brush segment 120 intersects the projection of the extension 1211 on the axis of the brush wheel 110. The extension portion 1211 on at least one section of the brush body 120 can be located within the gap between the two sections of the brush body 120, thereby cleaning the area corresponding to the gap between the two sections of the brush body 120. The cleaning effect at the gap is ensured by extending the extension portion 1211 that covers the middle seam of the cleaning roller brush 100.

[0052] Furthermore, each brush body 120 has an extension 1211 every other row. When the cleaning roller brush 100 is assembled, the brush teeth of each row of the two brush bodies 120 are aligned and joined together. Every other row of brush teeth without extensions is replaced by a row of brush teeth with extensions. The extensions of the two brush bodies 120 extend towards each other and intersect at the center seam of the brush wheel 110. This arrangement allows for reliable brushing of the surface to be cleaned at the center seam using multiple sets of extensions 1211, while avoiding excessive friction caused by too many extensions 1211 when the two brush wheels 110 rotate at different speeds, thus ensuring smooth rotation of the brush wheel 110.

[0053] Those skilled in the art will understand that the type of brush teeth provided in the extended portion 1211 is not limited. The extended portion 1211 can be provided on the brush teeth of the water collection section 123 or on the brush teeth of the extension section 124. The type of brush teeth provided in the extended portion 1211 can be adjusted according to the specific brush tooth arrangement scheme of the cleaning roller brush 100.

[0054] Preferably, see below. Figure 5 Along the axial direction of the brush body 120, the elongated portion 1211 includes a first end connected to the brush tooth body 1212 and a second end opposite to the first end. For example... Figure 5As shown, the brushing side edge 1213 of the extended portion is flush with the brush tooth body 1212, and the width dimension of the extended portion 1211 (i.e., the side edge of the extended portion 1211 near the brush wheel) is... Figure 5 The radial outward extension of the brush body 120 to the edge of the elongation 1211 gradually decreases from the first end to the second end, so that the shape of the elongation 1211 is close to that of a right trapezoid.

[0055] The brushing side of the elongated portion 1211 can be understood as the side of the elongated portion 1211 that is used to contact the cleaning target (such as the pool wall). Specifically, the brushing side of the elongated portion 1211 is the side of the elongated portion 1211 that is away from the axis of the brush wheel 110. Similarly, the side of the brush tooth body 1212 that is away from the axis of the brush wheel 110 is the brushing side of the brush tooth body 1212. The brushing side edge 1213 of the elongated portion is flush with the brush tooth body 1212, meaning that the edge of the brushing side of the elongated portion 1211 is collinear with the edge of the brush tooth body 1212.

[0056] In this embodiment, along the axis of the brush wheel 110, the elongated portion 1211 includes a first end connected to the brush tooth body 1212 and a second end opposite to the first end. By setting the brushing side edge 1213 of the elongated portion to be flush with the brush tooth body 1212, it is easier for the elongated portion 1211 and the brush tooth body 1212 to simultaneously contact the cleaning target, thereby improving cleaning efficiency. By setting the width of the elongated portion 1211 to gradually decrease from the first end to the second end, interference when the elongated portions 1211 of the two brush bodies 120 cross or misalign can be reduced, allowing the elongated portion 1211 to maintain its predetermined shape as much as possible, thus ensuring the strength of the brush tooth 121 where the elongated portion 1211 is located.

[0057] In some alternative embodiments, the brush wheel 110 and the brush body 120 are detachably connected.

[0058] As a feasible implementation, the brush body 120 is provided with a detachable connecting structure. When the connecting structure changes from a connected state to a detached state, the brush body 120 segment will break at the connecting structure, allowing the brush body 120 to be unfolded and detached from the brush wheel 110. Figure 2 As shown, the brush body 120 in its unfolded state includes a first side 1201, a second side 1202, a third side 1203, and a fourth side 1204. The first side 1201 and the second side 1202 are opposite sides of the brush body 120 along the axis of the brush wheel 110 when the brush body 120 is mounted on the brush wheel 110. The third side 1203 and the fourth side 1204 intersect with the first side 1201 and the second side 1202. A detachable connecting structure can be partially located on the third side 1203 and partially on the fourth side 1204, with the two parts working together to fix the brush body 120 to the brush wheel 110.

[0059] In some optional embodiments, the detachable connection structure includes a connecting buckle and a buckle socket. The connecting buckle is located on the third side 1203 of the brush body 120, and the buckle socket is located on the fourth side 1204 of the brush body 120. After the connecting buckle is installed into the buckle socket, it can engage with the fourth side 1204 of the brush body 120, thereby achieving a detachable connection between the third side 1203 and the fourth side 1204 of the brush body 120. For example, the connecting buckle includes a buckle body and a snap-fit ​​portion. One end of the snap-fit ​​portion is connected to the buckle body, and the snap-fit ​​portion can be perpendicular to the buckle body. One end of the buckle body is connected to the third side 1203 of the brush body 120. When the connecting buckle is in the installed state of being installed into the buckle socket, the third side 1203 of the brush body 120 and the snap-fit ​​portion are located on opposite sides of the buckle socket, and the snap-fit ​​portion engages with the edge of the buckle socket. The connecting clip and / or brush body 120 can be made of flexible materials with a certain degree of hardness, such as rubber or plastic, so that the connecting clip can be installed into / removed from the clip socket by deforming the connecting clip and / or brush body 120. At the same time, it can also ensure the plugging and locking state between the connecting clip and the clip socket.

[0060] As a feasible implementation, the brush wheel 110 is provided with a connection structure for mounting the brush body 120. The connection structure is detachably connected to the brush body 120. The connection structure can be a connecting buckle, bolt or other suitable structure, and this application does not limit it.

[0061] As another feasible implementation, the aforementioned detachable connection structures can also be distributed on the sheet-like main body of the brush body 120. For example, multiple first detachable connection structures are distributed on the side of the sheet-like main body of the brush body 120 without brush teeth, and multiple second detachable connection structures are correspondingly provided on the surface of the brush wheel 110 that is wrapped around the brush body 120. When the brush body 120 is wrapped and fixed on the brush wheel 110, the first detachable connection structures and the second detachable connection structures cooperate in groups to maintain the state in which the sheet-like main body of the brush body 120 is wrapped and fixed on the brush wheel 110.

[0062] In this embodiment, the brush wheel 110 and the brush body 120 are detachably connected, which makes it easy to replace the brush body 120 when it is severely worn or damaged, without having to replace the entire roller brush, thereby reducing the cost of using the cleaning roller brush 100.

[0063] like Figure 6 As shown in the figure, this application embodiment also provides an underwater cleaning robot 10, which is mainly used to clean the underwater parts of various structures, such as the bottom and side walls of pools, sewage treatment ponds, landscape ponds, etc., as well as the bottom and side walls of artificial waterways such as artificial rivers. The following description takes the cleaning of a pool as an example.

[0064] In this embodiment, the underwater cleaning robot 10 includes a first roller brush 11. Specifically, the first roller brush 11 can be the cleaning roller brush 100 described in any of the above embodiments.

[0065] In some optional embodiments, the underwater cleaning robot 10 may further include components such as a water pump, a filter basket, drive wheels, and a drive motor. The drive wheels, drive motor, and first roller brush 11 can be connected by gears or a transmission belt. When the underwater cleaning robot 10 is working, the drive motor drives the corresponding drive wheels to rotate, causing the drive wheels to move the underwater cleaning robot 10 in the pool and simultaneously rotate the first roller brush 11, cleaning the bottom or side walls of the pool through the rotation of the first roller brush 11. Furthermore, while moving in the pool, the underwater cleaning robot 10 can also use the water pump to draw water and / or contaminants into the filter basket. After filtering the water and / or contaminants through the filter basket, the contaminants are retained inside the filter basket, and the filtered water is discharged back into the pool. This process is repeated to complete the filtration of the pool water, thereby achieving the purpose of cleaning the pool.

[0066] In this embodiment, the underwater cleaning robot 10 includes a first roller brush 11. Specifically, the first roller brush 11 can be the cleaning roller brush 100 described in any of the above embodiments.

[0067] It should be understood that the underwater cleaning robot 10 provided in this application embodiment is based on the same inventive concept as the aforementioned cleaning roller brush 100 embodiment, and can achieve the same effect. Moreover, it can guide the water flow and pollutants to the water inlet 13 at the bottom of the underwater cleaning robot 10 through the water collection section 123 of the first roller brush 11, so that the underwater cleaning robot 10 can suck up the water flow and pollutants through the water inlet 13.

[0068] like Figure 7 As shown, in some optional embodiments, the underwater cleaning robot 10 further includes a second roller brush 12, with the first roller brush 11 and the second roller brush 12 respectively disposed on the front and rear sides of the underwater cleaning robot 10.

[0069] The second roller brush 12 can be detachably mounted on the underwater cleaning robot 10, so that it can be removed when it is inconvenient to use, allowing the underwater cleaning robot 10 to adapt to more usage scenarios. Similar to the first roller brush 11, the rear roller brush may also include two rollers and two brush bodies 120 to further facilitate the disassembly and installation of the second roller brush 12.

[0070] In this embodiment, the underwater cleaning robot 10 further includes a second roller brush 12, with the first roller brush 11 and the second roller brush 12 respectively disposed on the front and rear sides of the underwater cleaning robot 10. Through the first roller brush 11 and the second roller brush 12 located on the front and rear sides of the cleaning robot, water flow and contaminants can be swept towards the water inlet 13 of the underwater cleaning robot 10 chassis from both directions, greatly improving the cleaning efficiency of the underwater cleaning robot 10.

[0071] It should be noted that, depending on the implementation needs, the various components / steps described in the embodiments of this application can be broken down into more components / steps, or two or more components / steps or parts of the operation of components / steps can be combined into new components / steps to achieve the purpose of the embodiments of this application.

[0072] The methods described above according to the embodiments of this application can be implemented in hardware, firmware, or implemented as software or computer code that can be stored in a recording medium (such as CD-ROM, RAM, floppy disk, hard disk, or magneto-optical disk), or implemented as computer code originally stored in a remote recording medium or a non-transitory machine-readable medium and to be stored in a local recording medium after being downloaded via a network. Thus, the methods described herein can be stored as software processing on a recording medium using a general-purpose computer, a dedicated processor, or programmable or dedicated hardware (such as an application-specific integrated circuit (ASIC) or a field-programmable gate array (FPGA)).
