Description

Technical Field

[0001] This application relates to the field of robotics, specifically to a cleaning robot. Background Technology

[0002] Pool cleaning robots are used to remove trash from underwater surfaces, significantly reducing the difficulty and labor costs of underwater cleaning. However, existing pool cleaning robots often have trash that easily adheres to their roller brushes. This trash, as the brush rotates, doesn't easily flow into the trash can with the water, greatly reducing the cleaning effectiveness. Furthermore, when trash accumulates on the roller brush, it can also affect its rotation, thus impacting the robot's normal operation. Summary of the Invention

[0003] This application provides a cleaning robot with high cleaning efficiency.

[0004] This application provides a cleaning robot, the cleaning robot comprising:

[0005] The main body has a receiving cavity, one end of which is formed with an opening;

[0006] A waste collection device, at least partially located within the receiving cavity, the waste collection device having a waste collection port located near the opening;

[0007] A cleaning brush, located at the opening and rotatably connected to the two opposite sidewalls of the receiving cavity, is used to push the garbage toward the garbage collection port;

[0008] A front beam assembly is horizontally disposed on two opposite side walls of the accommodating cavity and is located between the waste collection device and the cleaning brush. The waste adhering to the cleaning brush can rotate under the action of the cleaning brush until it contacts the front beam assembly, so that the waste falls off the cleaning brush and flows to the waste collection port.

[0009] Furthermore, the cleaning brush includes a rotating shaft and multiple sets of brush blades. The rotating shaft is rotatably connected to the main body and extends along a first direction. The multiple sets of brush blades are spaced apart around the outer periphery of the rotating shaft. Each set of brush blades includes multiple bristles spaced apart sequentially along the first direction. The blocking member includes a main body and multiple protrusions. The multiple protrusions are spaced apart along the first direction on the surface of the main body facing the cleaning brush. The protrusions are at least partially embedded between two adjacent bristles.

[0010] Furthermore, the end faces of the multiple sets of brush blades facing away from the rotating shaft form a cylindrical surface, and the surface of the main body facing the cleaning brush is an arc-shaped cylindrical surface, which is coaxially arranged with the cylindrical surface.

[0011] Furthermore, the distance d1 between the body and the end face of the brush blade facing away from the rotating shaft is in the range of 0.7mm≤d1≤1.5mm.

[0012] Furthermore, the cleaning brush and the front beam assembly are arranged along the second direction, and the protrusion extends along the third direction; the size of the protrusion gradually decreases at least partially from the end connected to the body portion toward the end of the protrusion away from the body portion; along the third direction, the size of the protrusion gradually increases at least partially from the end near the opening toward the end away from the opening, wherein the first direction, the second direction and the third direction intersect each other.

[0013] Furthermore, the depth d2 of the protrusion embedded in the cleaning brush is in the range of 4mm≤d2≤10mm.

[0014] Furthermore, the spacing s1 between two adjacent bristles in the same group of brush blades ranges from 2.0mm ≤ s1 ≤ 3.0mm; along the first direction, the thickness w1 of the protrusion ranges from 1.0mm ≤ w1 ≤ 1.5mm.

[0015] Furthermore, the blocking member also includes a first snap-fit ​​portion, which is disposed on the surface of the body portion away from the plurality of protrusions; the mounting member includes a mounting portion and a second snap-fit ​​portion, the mounting portion is connected to the body portion at opposite ends along a first direction, the second snap-fit ​​portion is disposed on the side of the mounting portion facing the blocking member, and the first snap-fit ​​portion and the second snap-fit ​​portion engage in a snap-fit ​​cooperation.

[0016] Furthermore, the blocking member also includes a first insertion portion, which is spaced apart from the first snap-fit ​​portion and disposed on the side of the body portion away from the protrusion portion; the mounting member also includes a second insertion portion, which is spaced apart from the second snap-fit ​​portion and disposed on the side of the mounting portion facing the blocking member, and the first insertion portion and the second insertion portion are inserted into each other.

[0017] Furthermore, the mounting component also includes a third snap-fit ​​portion, which is disposed on the side of the mounting component facing away from the blocking member. The waste collection device includes a waste collection bin and a fourth snap-fit ​​portion. The waste collection bin has a waste collection opening on the side facing the front beam assembly. The fourth snap-fit ​​portion and the waste collection opening are disposed on the side of the waste collection bin facing the mounting component. The third snap-fit ​​portion and the fourth snap-fit ​​portion engage in a snap-fit ​​cooperation.

[0018] The cleaning robot described in this embodiment includes a main body, a waste collection device, a cleaning brush, and a front beam assembly. The front beam assembly is disposed between the cleaning brush and the waste collection device. When the cleaning robot cleans the water surface, the cleaning brush rolls and draws waste in the water into the waste collection inlet, which then enters the waste collection device, thus cleaning the waste on the water surface. When waste adheres to the cleaning brush, as the waste rotates to the front beam assembly, the front beam assembly causes the waste to fall from the surface of the cleaning brush to the vicinity of the waste collection inlet below, thereby carrying the water flow into the waste collection device. This effectively prevents waste from adhering to the cleaning brush and improves the waste cleaning effect. Attached Figure Description

[0039] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0040] It should be noted that, for ease of explanation, the same reference numerals denote the same components in the embodiments of this application, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments.

[0041] Pool cleaning robots are used to remove trash from underwater surfaces, significantly reducing the difficulty and labor costs of underwater cleaning. However, existing pool cleaning robots often have trash that easily adheres to their roller brushes. This trash, as the brush rotates, doesn't easily flow into the trash can with the water, greatly reducing the cleaning effectiveness. Furthermore, when trash accumulates on the roller brush, it can also affect its rotation, thus impacting the robot's normal operation.

[0042] Please see Figures 1 to 4 This application provides a cleaning robot 100, which includes a main body 10, a waste collection device 20, a cleaning brush 30, and a front beam assembly 40. The main body 10 has a receiving cavity 11 on one side, with an opening 111. The waste collection device 20 is located in the receiving cavity 11 and connected to the main body 10, and is used to collect waste. The waste collection device 20 has a waste collection port 21. The cleaning brush 30 is located in the receiving cavity 11 and rotatably connected to the main body 10. The cleaning brush 30 is positioned near the waste collection port 21 and is used to clean and allow waste to enter the waste collection device 20. The front beam assembly 40 is disposed between the cleaning brush 30 and the waste collection device 20. The front beam assembly 40 is used to prevent waste from adhering to the cleaning brush 30, thereby improving the cleaning effect.

[0043] In other words, the cleaning robot of this application includes a main body 10, a waste collection device 20, a cleaning brush 30, and a front beam assembly 40. The main body 10 has a receiving cavity 11, one end of which is formed with an opening 111; the waste collection device 20 is at least partially located within the receiving cavity 11, and the waste collection device 20 has a waste collection port 21, which is close to the opening 111; the cleaning brush 30 is located at the opening 111 and is rotatably connected to two opposite side walls of the receiving cavity 11, for pushing the waste toward the waste collection port 21; the front beam assembly 40 is transversely arranged on two opposite side walls of the receiving cavity 11, and the front beam assembly 40 is located between the waste collection device 20 and the cleaning brush 30, and the waste adhering to the cleaning brush 30 can be rotated under the action of the cleaning brush 30 to contact the front beam assembly 40, so that the waste falls off the cleaning brush 30 and flows toward the waste collection port 21.

[0044] The cleaning robot 100 of this application embodiment can be applied to cleaning trash in swimming pools, ponds, etc. It can clean trash on the water surface, and can also submerge underwater to clean underwater trash, as well as clean the surface of the pool bottom and side walls.

[0045] The cleaning robot 100 in this embodiment has a first state (such as...) Figure 1 (as shown) and the second state (as shown) Figure 2 (As shown). The first state is an upright state for underwater cleaning. When the cleaning robot 100 is in the second state, the opening 111 of the accommodating cavity 11 faces downward (along the direction of gravity). The second state is an inverted state for surface cleaning. When the cleaning robot 100 is in the second state, the opening 111 of the accommodating cavity 11 faces upward (the opening 111 faces the opposite direction of gravity). The garbage collection port 21 is located below the cleaning brush 30 and the front beam assembly 40.

[0046] It should be noted that the garbage collection device 20 is used to collect garbage when the cleaning robot 100 is in the second state, i.e., when the water surface is being cleaned.

[0047] It is understood that the garbage collection port 21 is located on the side of the garbage collection device 20 facing the front beam assembly 40 and the cleaning brush 30, and is disposed away from the opening 111 of the receiving cavity.

[0048] The cleaning robot 100 described in this embodiment includes a main body 10, a waste collection device 20, a cleaning brush 30, and a front beam assembly 40. The front beam assembly 40 is disposed between the cleaning brush 30 and the waste collection device 20. When the cleaning robot 100 cleans the water surface, the cleaning brush 30 rolls and rolls the waste in the water into the waste collection port 21, which then enters the waste collection device 20 to clean the waste on the water surface. When waste adheres to the cleaning brush 30, as the waste rotates with the cleaning brush 30 to the front beam assembly 40, the front beam assembly 40 causes the waste to fall from the surface of the cleaning brush 30 to the vicinity of the waste collection port 21 below, thereby carrying the water flow into the waste collection device 20. This effectively prevents waste from adhering to the cleaning brush 30 and improves the waste cleaning effect.

[0049] Please see Figures 5 to 8 In some embodiments, the cleaning brush 30 includes a rotating shaft 31 and multiple sets of brush blades 32, the rotating shaft 31 being rotatably connected to the main body 10 and the rotating shaft 31 being along a first direction (e.g., Figure 1 Extending from (arrow X), the multiple sets of brush blades 32 are spaced apart around the outer periphery of the rotating shaft 31, and each set of brush blades 32 includes a plurality of bristles 321 arranged at intervals along a first direction. The front beam assembly 40 includes a blocking member 42, which includes a body portion 421 and a plurality of protrusions 422. The plurality of protrusions 422 are spaced apart along the first direction on the surface of the body portion 421 facing the cleaning brush 30, and the protrusions 422 can be at least partially embedded between two adjacent bristles 321.

[0050] Understandably, the cleaning brush 30 and the front beam assembly 40 both extend along a first direction, while the cleaning brush 30, the front beam assembly 40, and the waste collection device 20 extend along a second direction (e.g., ...). Figure 1 (As indicated by arrow Y) arranged in a pattern where the first direction intersects the second direction. In one specific embodiment, the first direction is perpendicular to the second direction.

[0051] In this embodiment, the protrusion 422 is at least partially embedded between two adjacent bristles 321. This allows the protrusion 422 to better dislodge debris from the surface of the bristles 321 and from within them, preventing debris from accumulating on the cleaning brush 30. The debris falls to the vicinity of the debris collection port 21 below and enters the debris collection device 20 with the water flow, thus improving the cleaning effect. Furthermore, it prevents debris from rotating around the cleaning brush 30 and falling back into the water, further enhancing cleaning efficiency. Moreover, the multiple protrusions 422 also act as reinforcing ribs, increasing the mechanical strength and service life of the blocking member 42. Furthermore, when cleaning the water surface and the cleaning brush 30 has a deep water intake, the multiple protrusions 422 divide the water rolled up by the rotating cleaning brush 30 into strips of water curtains. This can better prevent garbage from falling back to the water surface after rotating around the cleaning brush 30 with the water flow and failing to enter the garbage collection device 20. This can significantly improve the garbage cleaning efficiency and effect.

[0052] Please see Figure 7 In some embodiments, the end faces of the multiple sets of brush blades 32 facing away from the rotating shaft 31 form a cylindrical surface (as shown by the dotted circle O in the figure), and the surface of the body part 421 facing the cleaning brush 30 is an arc cylindrical surface 4211, which is coaxially arranged with the cylindrical surface.

[0053] Understandably, the end faces of multiple brush blades 32 facing away from the rotating shaft 31 are fitted with curved surfaces to form cylindrical surfaces.

[0054] Understandably, when cut along a direction parallel to the second direction, the multiple brush blades 32 of the cleaning brush 30 form a circle with their end faces away from the rotating shaft 31, and the surface facing the cleaning brush 30 is an arc. The center of this arc coincides with the circle.

[0055] It should be noted that the arc cylindrical surface 4211 is coaxially arranged with the cylindrical surface. Understandably, the central axis of the arc cylindrical surface 4211 coincides with the central axis of the cylindrical surface.

[0056] In this embodiment, by making the arcuate cylindrical surface 4211 of the body part 421 facing the cleaning brush 30 coaxial with the cylindrical surface of the outer periphery of the cleaning brush 30, interference between the cleaning brush 30 and the body part 421 can be better avoided when the cleaning brush 30 rotates. In addition, it can better knock off the garbage on the surface of the cleaning brush 30, thereby improving the garbage cleaning effect.

[0057] Optionally, the bristles 321 of the cleaning brush 30 at least partially protrude from the body 10. It can also be understood that the bristles 321 of the cleaning brush 30 at least partially protrude from the opening 111 of the receiving cavity 11. This can better improve the garbage cleaning effect, especially when the cleaning robot 100 is in its first state and performing underwater cleaning, it can better clean the surface of the bottom or side walls of pools or ponds, avoiding the problem of large cleaning dead areas in this situation, thereby improving the cleaning effect of the cleaning robot 100.

[0058] Please see also Figure 9 In some embodiments, the distance d1 between the body portion 421 and the end face of the brush 32 facing away from the rotating shaft 31 is in the range of 0.7mm≤d1≤1.5mm.

[0059] Specifically, the distance d1 between the body part 421 and the end face of the brush 32 facing away from the rotating shaft 31 can be, but is not limited to, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, etc.

[0060] In this embodiment, if the distance d1 between the body part 421 and the end face of the brush 32 facing away from the rotating shaft 31 is too small, the cleaning brush 30 will easily interfere with the body part 421 when it rotates, affecting the normal operation of the cleaning robot 100. If the distance d1 between the body part 421 and the end face of the brush 32 facing away from the rotating shaft 31 is too large, garbage will easily enter the gap between the cleaning brush 30 and the body part 421 when the cleaning brush 30 rotates, and may not be able to be carried out, affecting the continuous normal operation of the cleaning brush 30 and the garbage cleaning efficiency. In addition, it may not be able to knock the garbage off, so that the garbage falls back to the water surface after the cleaning brush 30 rotates once, and cannot enter the garbage collection device 20, reducing the garbage cleaning effect.

[0061] Furthermore, the distance d1 between the body part 421 and the end face of the brush 32 facing away from the rotating shaft 31 is in the range of 0.9mm≤d1≤1.1mm. This allows the cleaning robot 100 to perform garbage cleaning more continuously while improving garbage cleaning efficiency and effect.

[0062] Please see again Figure 7 In some embodiments, the cleaning brush 30 and the front beam assembly 40 are arranged along a second direction, and the protrusion 422 is arranged along a third direction (e.g., Figure 1(As indicated by arrow Z) extending; the size of the protrusion 422 gradually decreases at least partially from the end connected to the body portion 421 toward the end of the protrusion 422 away from the body portion 421; along the third direction, the size of the protrusion 422 gradually increases at least partially from the end near the opening 111 toward the end away from the opening 111, wherein the first direction, the second direction and the third direction intersect each other.

[0063] In one specific embodiment, the first direction, the second direction, and the third direction are perpendicular to each other.

[0064] Understandably, the size of the protrusion 422 gradually decreases from the end connected to the body portion 421 toward the end of the protrusion 422 near the waste collection device 20; and along the third direction, the size of the protrusion 422 gradually increases from the end near the opening 111 toward the end near the waste collection port 21.

[0065] Optionally, the end face of the protrusion 422 facing away from the body portion 421 is an arc surface.

[0066] In this embodiment, by making the size of the protrusion 422 gradually decrease from the end connected to the body portion 421 toward the end of the protrusion 422 away from the body portion 421, and by making the size of the protrusion 422 gradually increase from the end near the opening 111 toward the end away from the opening 111, the protrusion 422 can promptly knock the garbage off when it rolls to the blocking member 42 with the cleaning brush 30. The size of the end of the protrusion 422 near the garbage collection port 21 is larger than the size of the end away from the garbage collection port 21, which also increases the probability of knocking off the garbage, so that the garbage can enter the garbage collection port 21 with the water flow, improving the garbage cleaning efficiency. In addition, the protrusion 422 extends in a third direction, so that the protrusion 422 connects more to the body portion 421 in a third direction, thereby better strengthening the body portion 421 and giving the blocking member 42 better mechanical strength.

[0067] Optionally, along the third direction upwards, the end of the protrusion 422 opposite to the opening 111 protrudes from the end of the body portion 421 opposite to the opening 111; in other words, along the third direction upwards, the end of the protrusion 422 near the garbage collection port 21 protrudes from the end of the body portion 421 opposite to the garbage collection port 21. This allows the garbage to be knocked off or bumped by the protrusion 422 before it reaches the body portion 421, further reducing the probability of garbage being caught in the gap between the cleaning brush 30 and the body portion 421. This improves garbage cleaning efficiency while preventing garbage from getting caught in the gap between the cleaning brush 30 and the body portion 421, thus avoiding interference with the normal operation of the cleaning brush 30.

[0068] Please see again Figure 9 In some embodiments, the depth d2 of the protrusion 422 embedded in the cleaning brush 30 is in the range of 4mm≤d2≤10mm.

[0069] Specifically, the depth d2 of the protrusion 422 embedded in the cleaning brush 30 can be, but is not limited to, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.8mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, etc.

[0070] In this embodiment, if the depth d2 of the protrusion 422 embedded in the cleaning brush 30 is too small, the probability of the protrusion 422 knocking or knocking away the garbage inside the cleaning brush 30 is reduced, thus reducing cleaning efficiency. Furthermore, it easily leads to garbage residue inside the cleaning brush 30, requiring the cleaning robot 100 to clean the garbage from the cleaning brush 30 after a period of use, reducing the garbage cleaning effect and continuous usage time of the cleaning robot 100. Although a larger depth d2 of the protrusion 422 embedded in the cleaning brush 30 makes it less likely for garbage to accumulate on the cleaning brush 30, if the depth d2 is too large, the roots of the bristles 321 are easily subjected to excessive force, making the bristles 321 prone to damage (when the embedding is too shallow, the bristles 321 will bend on their own to protect themselves). In this embodiment, when the depth d2 of the protrusion 422 embedded in the cleaning brush 30 is 4mm≤d2≤10mm, it can better reduce the residual debris on the cleaning brush 30, while also better protecting the bristles 321, so that the bristles 321 have a longer service life.

[0071] Please see again Figure 5 In some embodiments, the distance s1 between two adjacent bristles 321 of the same group of brush blades 32 ranges from 2.0 mm to 3.0 mm. It can be understood that the distance s1 between two adjacent bristles 321 along the first direction ranges from 2.0 mm to 3.0 mm.

[0072] Specifically, the distance s1 between two adjacent bristles 321 of the same group of brush blades 32 can be, but is not limited to, 2.0mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3.0mm, etc. If the distance s1 between two adjacent bristles 321 of the same group of brush blades 32 is too small, the gap between the protrusion 422 and the bristles 321 will be too small when the protrusion 422 is inserted, which will easily cause interference and affect the normal rotation of the cleaning brush 30. If the distance s1 between two adjacent bristles 321 of the same group of brush blades 32 is too large, the arrangement of the bristles 321 will be too sparse, which will easily prevent some garbage from being carried into the garbage collection port 21 by the cleaning brush 30, thus affecting the garbage cleaning effect.

[0073] Please see again Figure 8 Optionally, along the first direction, the thickness w1 of the protrusion 422 is in the range of 1.0mm ≤ w1 ≤ 1.5mm. Along the first direction, the thickness w1 of the protrusion 422 can be, but is not limited to, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, etc. If the thickness w1 of the protrusion 422 is too small along the first direction, the mechanical strength of the protrusion 422 is reduced; if the thickness w1 of the protrusion 422 is too large along the first direction, the distance between the protrusion 422 and the bristles 321 is reduced, making interference with the bristles 321 more likely. Furthermore, if the thickness w1 of the protrusion 422 is too thick, it increases the cost and weight of the blocking member 42.

[0074] In one specific embodiment, along the first direction, the spacing between two adjacent bristles 321 is 2.5 mm, the thickness of the protrusion 422 is 1.2 mm, and the gap between the bristles 321 and the protrusion 422 is 0.65 mm.

[0075] Please see Figure 10 and Figure 11 In some embodiments, the rotating shaft 31 of this application includes a brush mounting portion 311 and a rotating connecting portion 312 coaxially arranged. Both the brush mounting portion 311 and the rotating connecting portion 312 extend along the axial direction of the rotating shaft 31 (i.e., both the brush mounting portion 311 and the rotating connecting portion 312 extend along the first direction). The plurality of brush blades 32 are spaced apart on the outer peripheral surface of the brush mounting portion 311 in the circumferential direction. The brush mounting portion 311 is located on the outer peripheral side of the rotating connecting portion 312 and an inner cavity 3121 is formed between the two. At least one end of the brush mounting portion 311 is provided with an opening 3122. The opening 3122 is used to allow water to flow into the inner cavity 3121 or to allow water in the inner cavity 3121 to flow out.

[0076] Optionally, the rotating connection part 312 and the brush mounting part 311 are an integral structure. Understandably, the rotating connection part 312 and the brush mounting part 311 are different parts of the same component.

[0077] Understandably, the rotating connecting portion 312 is disposed within the brush mounting portion 311. The brush mounting portion 311 is sleeved on the outer periphery of the rotating connecting portion 312 and connected to it. Optionally, the brush mounting portion 311 and the rotating connecting portion 312 may be connected at their ends, or they may be connected at their middle, for example, the middle position of the outer surface of the rotating connecting portion 312 is connected to the middle position of the inner surface of the brush mounting portion 311. Figure 10 In the embodiment, the brush mounting part 311 and the rotating connection part 312 are connected at the end.

[0078] Optionally, multiple sets of brush blades 32 are arranged circumferentially around the brush mounting portion 311, and multiple bristles 321 of the same set of brush blades 32 are arranged at intervals along a first direction on the brush mounting portion 311.

[0079] Optionally, at least one end of the brush mounting portion 311 is provided with an opening 3122. In other words, one end of the brush mounting portion 311 is the opening end 3122, and the opening 3122 connects the inner cavity 3121 with the outside. This opening 3122 facilitates the drainage of accumulated water in the inner cavity 3121 of the cleaning brush 30 or the entry of water. In this embodiment, one end of the brush mounting portion 311 is an open structure (with an opening 3122), so water is less likely to accumulate inside the brush mounting portion 311, reducing the weight of the cleaning robot 100 when it is lifted out. When there is accumulated water inside the brush mounting portion 311, the water can be poured out by tilting the cleaning robot 100 or tilting the cleaning brush 30. The open structure (with an opening 3122) at one end of the brush mounting portion 311 also increases the sinking speed of the cleaning robot 100 during the process of sinking to the bottom of the water, improving work efficiency.

[0080] In the related technology, the cleaning brush 30 needs to be connected to the gear assembly at one end of the brush mounting part 311. Therefore, an end cap is provided (i.e., one end of the brush mounting part 311 is a closed end). The end cap is connected to the gear assembly and has a through hole for water to flow in or out. However, because an end cap is provided at one end of the brush mounting part 311, the water flow rate is reduced, which slows down the drainage or water intake speed. It cannot drain or enter water quickly. Drainage occurs when the cleaning robot 100 is lifted out of the water. If drainage is not timely, the user needs to expend a lot of effort. Water intake occurs when the robot is put into the water to work. If water intake is slow, the robot will sink to the bottom very slowly, reducing work efficiency.

[0081] The rotating shaft 31 of this embodiment includes a brush mounting portion 311 and a rotating connecting portion 312 coaxially arranged. Both the brush mounting portion 311 and the rotating connecting portion 312 extend along the axial direction of the rotating shaft 31. The brushes are spaced circumferentially on the outer peripheral surface of the brush mounting portion 311. The brush mounting portion 311 is located on the outer peripheral side of the rotating connecting portion 312, and an inner cavity 3121 is formed between the two. At least one end of the brush mounting portion 311 is provided with an opening 3122. The opening 3122 is used to allow water to flow into the inner cavity 3121 or to allow water in the inner cavity 3121 to flow out. The opening 3122 can accelerate the drainage or water intake inside the rotating shaft 31. The faster drainage speed means that the user does not need to expend much effort when lifting the cleaning robot 100 out of the water. The faster water intake speed means that when the user puts the robot into the water to work, the cleaning robot 100 sinks to the bottom faster, improving work efficiency.

[0082] Please see Figure 12 and Figure 13 In some embodiments, the blocking member 42 further includes a first engaging portion 423 disposed on the surface of the body portion 421 opposite to the plurality of protrusions 422; the front beam assembly further includes a mounting member 41 disposed between the blocking member 42 and the waste collection device 20, the mounting member 41 including a mounting portion 411 and a second engaging portion 412, the mounting portion 411 connecting the body 10 at opposite ends along a first direction, the second engaging portion 412 disposed on the side of the mounting portion 411 facing the blocking member 42, the first engaging portion 423 engaging with the second engaging portion 412 to connect the blocking member 42 to the mounting member 41.

[0083] Understandably, the first snap-fit ​​portion 423 is positioned away from the cleaning brush 30.

[0084] Optionally, the number of the first snap-fit ​​portion 423 can be one or more. When there are multiple first snap-fit ​​portions 423, the multiple first snap-fit ​​portions 423 are spaced apart on the surface of the body portion 421 away from the multiple protrusions 422.

Compared to a solution with only one pair of first latching portions 423 and second latching portions 412, the cooperation of multiple pairs of first latching portions 423 and second latching portions 412 can make the connection between the blocking member 42 and the mounting member 41 more stable, and can better prevent rotation or misalignment between the blocking member 42 and the mounting member 41.

[0087] Optionally, the first engaging portion 423 can be a hook or a slot, and the second engaging portion 412 can be a hook or a slot.

This should not be construed as a limitation on the first latching part 423 and the second latching part 412 of the embodiments of this application, nor should it be construed as a limitation on the blocking member 42 and the mounting member 41 of the embodiments of this application.

[0088] In this embodiment, by providing the first latching part 423 and the second latching part 412, the blocking member 42 and the mounting member 41 can be stably connected together. In addition, the assembly between the blocking member 42 and the mounting member 41 can be better simplified. The structure is simple and easy to implement.

[0089] In some embodiments, the blocking member 42 further includes a first insertion portion 424, which is spaced apart from the first snap-fit ​​portion 423 on the side of the body portion 421 opposite to the protrusion 422; the mounting member 41 further includes a second insertion portion 413, which is spaced apart from the second snap-fit ​​portion 412 on the side of the mounting portion 411 facing the blocking member 42, and the first insertion portion 424 and the second insertion portion 413 are inserted into each other.

[0090] Optionally, the first plug-in portion 424 has a plug hole 4241, and the second plug-in portion 413 is a protruding post.

[0091] In this embodiment, the insertion and engagement of the first insertion part 424 and the second insertion part 413, combined with the first snap-fit ​​part 423 and the second snap-fit ​​part 412, can make the connection between the blocking member 42 and the mounting member 41 more stable and improve the mechanical strength of the front beam assembly 40.

[0092] Please see again Figure 3 and Figure 12 In some embodiments, the mounting member 41 further includes a third snap-fit ​​portion 414, which is disposed on the side of the mounting member 411 opposite to the blocking member 42. The waste collection device 20 includes a waste collection bin 22 and a fourth snap-fit ​​portion 23. The waste collection bin 22 has a waste collection opening 21 on the side facing the front beam assembly 40. The fourth snap-fit ​​portion 23 and the waste collection opening 21 are disposed on the side of the waste collection bin 22 facing the mounting member 41. The third snap-fit ​​portion 414 and the fourth snap-fit ​​portion 23 engage to connect the mounting member 41 to the waste collection device 20.

[0093] Optionally, the number of the third latching portions 414 can be one or more. When there are multiple third latching portions 414, the multiple third latching portions 414 are spaced apart on the surface of the body portion 421 away from the multiple protrusions 422.

[0094] Optionally, the number of the fourth latching portions 23 can be one or more. When there are multiple fourth latching portions 23, the multiple fourth latching portions 23 are spaced apart on the surface of the mounting portion 411 facing the blocking member 42.

[0095] Optionally, the third latching part 414 and the fourth latching part 23 are configured in a one-to-one correspondence, with one third latching part 414 corresponding to one fourth latching part 23, and different third latching parts 414 corresponding to different fourth latching parts 23. Compared to a solution with only one pair of third latching parts 414 and fourth latching parts 23, the cooperation of multiple pairs of third latching parts 414 and fourth latching parts 23 can make the connection between the mounting part 41 and the garbage collection bin 22 more stable, and can better prevent rotation or misalignment between the mounting part 41 and the garbage collection bin 22.

[0096] Optionally, the third engaging portion 414 can be a hook or a slot, and the fourth engaging portion 23 can be a hook or a slot. In some embodiments, both the third engaging portion 414 and the fourth engaging portion 23 are hooks. In other embodiments, the third engaging portion 414 is a hook, and the fourth engaging portion 23 is a slot. In still other embodiments, the third engaging portion 414 is a slot, and the fourth engaging portion 23 is a hook. Figure 3 and Figure 12In this embodiment, the third latching part 414 is used as a slot and the fourth latching part 23 is used as a hook for illustration. This should not be construed as a limitation on the third latching part 414 and the fourth latching part 23 of this application embodiment, nor should it be construed as a limitation on the mounting part 41 and the garbage collection bin 22 of this application embodiment.

[0097] In this embodiment, by providing the third snap-fit ​​part 414 and the fourth snap-fit ​​part 23, the mounting part 41 and the garbage collection box 22 can be stably connected together. In addition, the assembly between the mounting part 41 and the garbage collection box 22 can be better simplified. The structure is simple and easy to implement.

[0098] Please see again Figure 3 and Figure 12 In some embodiments, the mounting member 41 further includes two third insertion portions 415, which are spaced apart along a first direction on opposite sides of the mounting portion 411; the main body 10 has a fourth insertion portion 12 on each of its opposite side walls along the first direction, and the third insertion portions 415 and the fourth insertion portions 12 are inserted into each other so that the mounting member 41 is inserted into the main body 10.

[0099] Optionally, the third insertion portion 415 is a protrusion, and the fourth insertion portion 12 is a slot, with the protrusion passing through the slot so that the mounting member 41 is inserted into the body 10. In other embodiments, the third insertion portion 415 may be a slot, and the fourth insertion portion 12 may be a protrusion, with the fourth insertion portion 12 inserted into the third insertion portion 415.

[0100] In this embodiment, the insertion and engagement of the third insertion part 415 and the fourth insertion part 12 makes the connection between the mounting part 41 and the main body 10 more stable.

[0101] Please see again Figure 13 In some embodiments, the mounting member 41 further includes a plurality of reinforcing ribs 416, which are spaced apart along a first direction on the side of the mounting portion 411 facing the blocking member 42, in order to improve the mechanical strength of the mounting member 41.

[0102] Please see Figure 6 , Figure 14 and Figure 15In some embodiments, the cleaning robot 100 further includes a travel wheel 50, a drive paddle 60, and a motor housing 70. The travel wheel 50 is rotatably disposed on the main body 10 and is used to drive the cleaning robot 100 to walk when the cleaning robot 100 is in a first state. The drive paddle 60 is rotatably disposed on the main body 10 and located on the side of the garbage collection device 20 away from the cleaning brush 30, and is used to drive the cleaning robot 100 to walk when the cleaning robot 100 is in a second state. The motor housing 70 is disposed on the main body 10 and is electrically connected to the travel wheel 50, the cleaning brush 30, and the drive paddle 60 respectively, and is used to drive the travel wheel 50, the cleaning brush 30, and the drive paddle 60 to rotate respectively.

[0103] Optionally, the main body 10 also has a receiving cavity 13 on the side opposite to the receiving cavity 11, the receiving cavity 13 being used to house the motor box 70. It should be noted that the opening 111 of the receiving groove is located opposite to the receiving cavity 13.

[0104] In some embodiments, the motor box 70 includes a walking motor 71 and two water pump motors 72. The walking motor 71 is electrically connected to the traveling wheel 50 and the drive paddle 60 respectively, and is used to drive the traveling wheel 50 and the drive paddle 60 to rotate respectively. The water pump motors 72 are used to control the cleaning robot 100 to sink into the water. The two water pump motors 72 are symmetrically arranged along a first direction.

[0105] It should be noted that the two water pump motors 72 can be installed adjacent to each other or spaced apart.

[0106] Understandably, the two water pump motors 72 are symmetrically arranged with an axis parallel to the second direction as the axis of symmetry.

[0107] Understandably, when the cleaning robot 100 is in the first state, i.e., performing underwater cleaning, the walking motor 71 drives the travel wheels 50 to rotate, thereby driving the cleaning robot 100 to walk; in addition, the water pump motor 72 is started to drive the water flow to spray out in the direction away from the cleaning brush 30, thereby providing downforce to the cleaning robot 100 so that the cleaning robot 100 gradually sinks to the bottom of the water; when the cleaning robot 100 is in the second state, i.e. performing surface cleaning, the walking motor 71 drives the paddle 60 to rotate, thereby driving the cleaning robot 100 to walk.

[0108] Optionally, the motor box 70 may also include electronic components such as batteries and circuit boards.

[0109] In this embodiment, the water pump motor 72 is relatively heavy. By symmetrically arranging the water pump motor 72 along the first direction, the gravity on both sides of the cleaning robot 100 along the direction of travel can be more balanced, which can provide better stability when entering the water and better maintain a horizontal state.

[0110] Please see Figure 3 and Figure 14 Optionally, the garbage collection bin 22 further includes a water inlet 221 and a water outlet (not shown). The water inlet 221 is disposed away from the motor box 70, and the water outlet is disposed facing the motor box 70. The water outlet is connected to the water pump motor 72. When the cleaning robot 100 needs to perform underwater cleaning, the cleaning robot 100 is upright, the water pump motor 72 is started, and water enters the garbage collection bin 22 from the water inlet 221 of the garbage collection device 20, passes through the water outlet, and enters the water pump motor 72. The water pump motor 72 sprays water in a direction away from the garbage collection device 20, thereby giving the cleaning robot 100 a force from the water pump motor 72 in the direction of the garbage collection device 20, so that the cleaning robot 100 gradually sinks to the bottom of the water under the action of this force, so as to perform underwater cleaning.

[0111] It should be noted that the position of the water nozzle of the main body 10 corresponding to the water pump motor 72 is hollowed out.
