[0033] See also Figure 1-13 As shown, the present invention discloses a swimming pool cleaning robot 100, which can be used to clean water areas at various locations in a pool.

[0034] The pool cleaning robot 100 includes a main body 10, a driving mechanism 20 for driving the main body 10 to move, and a roller brush 30 disposed at the bottom of the main body 10 and partially protruding from the main body 10 along a first direction in which the pool cleaning robot moves.

[0035] The main body 10 includes a first water flow channel 11 and a second water flow channel 12 for sucking water into the main body 10, and a trash can 13 accommodated in the main body 10. The first water flow channel 11 and the second water flow channel 12 are both connected to the trash can 13, and the trash can 13 is configured to filter the water flow in the first water flow channel 11 and the second water flow channel 12, filter and store the garbage in the water flow. The first water flow channel 11 and the second water flow channel 12 are arranged alternately. The first water flow channel 11 penetrates the main body 10 in the vertical direction, and the second water flow channel 12 penetrates the main body 10 in the horizontal direction, and the first water flow channel 11 and the second water flow channel 12 are not connected to each other. The trash can 13 includes a first receiving space 130 and a second receiving space 131 isolated from the first receiving space 130. The first receiving space 130 is connected to the first water flow channel 11, and the second receiving space 131 is connected to the second water flow channel 12.

[0036] In this embodiment, the first water flow channel 11 includes a first water inlet channel 110 and a first water outlet channel 111. The first water inlet channel 110 and the first water outlet channel 111 are connected through the first receiving space 130 of the trash bin 13. Water flows into the first water inlet channel 110, passes through the first receiving space 130 of the trash bin 13, and is filtered. Trash and other debris in the water flow are retained in the first receiving space 130. The filtered water flow is then discharged to the outside of the main body 10 through the first water outlet channel 111. The first water inlet channel 110 includes a first inlet 112 disposed at the bottom side of the main body 10. The first inlet 112 is configured to introduce water flow. A suction mechanism 113 is provided in the first water flow channel 11. The suction mechanism 113 is located at one end where the first water outlet channel 111 is connected to the first receiving space 130. The suction mechanism 113 is configured to provide suction.

[0037] In this embodiment, the second water flow channel 12 includes a second water inlet channel 120 and a second water outlet channel 121, which are connected through a second receiving space 131 of the trash bin 13. Water flows into the second water inlet channel 120, passes through the second receiving space 131 of the trash bin 13, and is filtered. Garbage and other debris in the water flow are retained in the second receiving space 131, and the filtered water flow is discharged to the outside of the main body 10 through the second water outlet channel 121. The second water inlet channel 120 includes a second inlet 123 disposed at the front side of the main body 10, and the second inlet 123 is configured to introduce water flow.

[0038] See also Figure 1-4As shown, the main body 10 includes an outer shell 101. The outer shell 101 includes a front wall 102 and a top wall 103 perpendicular to the front wall 102, a rear wall 104 arranged opposite to the front wall 102, and a bottom wall arranged opposite to the top wall 103. The outer shell 101 is divided into a lower half 106 and an upper half 107 matched with the lower half 106. A plurality of top drainage holes 1031 are provided on the top wall 103 of the outer shell. The top drainage holes 1031 are divided into two groups and symmetrically arranged on both sides of the second water flow channel 12. The first water outlet channel 111 is divided into two branches passing through both sides of the second water inlet channel 120 and connected to the top drainage holes 1031 respectively to discharge the water filtered from the first receiving space 130 out of the swimming pool cleaning robot 100.

[0039] In this embodiment, the second water flow channel 12 includes two second water outlet channels 121, which are symmetrically arranged on both sides of the second receiving space 131 and extend in a direction away from the second water inlet channel 120, that is, after the water flow in the second water inlet channel 120 passes through the second receiving space 131, it is discharged outward from the two second water outlet channels 121 on both sides.

[0040] The driving mechanism 20 includes a first power system 21 disposed on both sides of the main body 10 to enable the swimming pool cleaning robot 100 to walk on the bottom wall of a water body such as a swimming pool, and a second power system 22 disposed independently of the first power system 21 .

[0041] The second power system 22 is arranged at one end of the second water outlet channel 121 away from the trash can 13, and the water discharged through the second water outlet channel 121 can drive the second power system 22 to work so as to drive the swimming pool cleaning robot 100 to move. The second power system 22 can drive the swimming pool cleaning robot 100 to move together with the first power system 21, or can drive the swimming pool cleaning robot 100 to move alone when the first power system 21 cannot walk on the bottom wall of a water body such as a swimming pool, such as when it is suspended or floating on the water body. In this embodiment, the first power system 21 is a crawler chassis walking structure installed on both sides of the main body 10. In other embodiments, the first power system 21 can also be a wheeled chassis walking structure or other suitable structure that can drive the swimming pool cleaning robot 100 to walk on the bottom wall of a water body, and the present invention is not limited to this.

[0042] The second power system 22 includes two symmetrically arranged propulsion motors and a propeller 220. When the swimming pool cleaning robot 100 needs to be driven to move in a first direction in the water, the propulsion motor provides initial power. After the swimming pool cleaning robot 100 starts to move, the water flow in the second water outlet channel 121 is used as an auxiliary power to drive the propeller 220 to continue to operate, which can reduce the power required to be output by the propulsion motor and improve the endurance of the swimming pool cleaning robot 100 operating in water. The swimming pool cleaning robot 100 includes the ability to walk in a straight line and the ability to turn.

[0043] An end of the second water outlet channel 121 away from the trash bin 13 is provided with a water inlet and outlet 1214, and the second power system 22 is symmetrically arranged in the two second water outlet channels 121. The second power system 22 includes a propeller 220 close to the water inlet and outlet 1214 and a propulsion motor away from the water inlet and outlet 1214 relative to the propeller 220. The propulsion motor drives the propeller 220 to rotate forward to drive the swimming pool cleaning robot 100 to move in a first direction, and the propulsion drives the propeller 220 to rotate reversely to drive the swimming pool cleaning robot 100 to move in a second direction opposite to the first direction.

[0044] The second water outlet channel 121 includes an inner wall 1211 facing the trash bin 13 and an outer wall 1212 facing away from the trash bin 13. The second water outlet channel 121 is in one-way communication with the trash bin 13 via a one-way valve 1213 on the inner wall 1211. The second water outlet channel 121 is in one-way communication with the main body 10 via a one-way valve 1213 on the outer wall 1212.

[0045] like Fig.12 As shown, when the propeller 220 rotates forward, the water flowing into the second receiving space 131 passes through the one-way valve 1213 on the inner wall 1211 and enters the second water outlet channel 121, and flows out through the water inlet and outlet 1214 in the second direction, pushing the swimming pool cleaning robot 100 to move in the first direction, that is, forward.

[0046] like Fig.13 As shown, when the propeller 220 rotates in the opposite direction, the water flows into the second water outlet channel 121 through the water inlet and outlet 1214, and flows into the main body 10 through the one-way valve 1213 on the outer wall 1212 along the first direction, and flows out through the side drain port 1071 on the outer shell, so that the swimming pool cleaning robot 100 moves in the second direction, that is, retreats. In this embodiment, the angle between the flow direction of the water when it is ejected outward from the second water outlet channel 121 and the outer wall 1212 is 45 degrees, so that the water can be accurately discharged from the side drain port 1071 to the outside of the main body 10. In other embodiments, other angles can also be set, and the present invention is not limited to this.

[0047] In this embodiment, the one-way valve 1213 on the inner wall 1211 is a soft rubber that flips toward the inner side of the second water outlet channel 121, and the one-way valve 1213 on the outer wall 1212 is a soft rubber that flips toward the outer side of the second water outlet channel 121. In other embodiments, the one-way valve 1213 may also be other structures, and the present invention is not limited to this.

[0048] The pool cleaning robot 100 further includes a submersible floating mechanism 40. The submersible floating mechanism 40 is located in the main body 10 and is configured to drive the pool cleaning robot 100 to rise, sink and suspend, so that the pool cleaning robot 100 can stay at any position in the pool, meeting the requirements of cleaning operations in all water areas.

[0049] In summary, the swimming pool cleaning robot 100 of the present invention comprises a first water flow channel 11 and a second water flow channel 12, wherein the first water flow channel 11 can clean up the garbage attached to the bottom of the pool, and the second water flow channel 12 can clean up the garbage in the pool and on the water surface, and the cleaning is efficient, fast and more convenient. With the help of the submersible floating mechanism 40, it can realize the cleaning of any position in the pool, has strong practicality and is more widely used.
