[0067] The main control unit 2, the first power unit 31, the second power unit 32 and the power supply 33 are sealed and integrated in the sealed cabin 3; the main control unit 2 is electrically connected to the first power unit 31, the second power unit 32 and the power supply 33 respectively; the output shafts 37 of the first power unit 31 and the second power unit 32 extend out of the top of the sealed cabin 3;

[0068] The main control unit 2, the first power unit 31, the second power unit 32 and the power supply 33 need good sealing and waterproof properties. By integrating these core components into the sealed cabin 3, they can be isolated from the external environment, reduce interference and damage from the external environment, and effectively prevent the intrusion of water flow and liquid, reduce the failure rate, improve stability, and ensure the normal operation of the underwater cleaning robot;

[0069] The main control unit 2, the first power unit 31, the second power unit 32 and the power supply 33 can also be centrally managed to facilitate inspection and maintenance by maintenance personnel.

[0070] The housing 1 is provided with a receiving hole 13; the sealed cabin 3 is placed in the receiving hole 13 to achieve connection with the housing 1;

[0071] Specifically, in some embodiments of the present application, the shape of the receiving hole 13 matches the shape of the sealed cabin 3, and the shape of the receiving hole 13 is circular;

[0072] The circular structure of the receiving hole 13 can evenly distribute the external force applied thereto, reducing the risk of stress concentration; thereby improving the structural strength of the receiving hole 13 and reducing the risk of cracking and damage;

[0073] The circular receiving hole 13 is also easy to process, which can effectively improve production efficiency and reduce production costs.

[0074] Of course, there is no limitation on the specific shape of the receiving hole 13 .

[0075] The water spray unit 5 is provided with a first water spray area 51 and a second water spray area 52 which are independent of each other;

[0076] The bottom of the housing 1 is provided with a water inlet 14; the interior of the housing 1 is provided with a filter layer 15; the top of the housing 1 is connected to the water spray unit 5, forming a water flow filtering channel 16 from the water inlet 14, the filter layer 15 to the top of the housing 1;

[0077] Specifically, in some embodiments of the present application, Figure 6As shown in the figure, the arrow is the approximate flow direction of the water flow, and the dotted area in the figure is a simple schematic diagram of the water flow filtering channel 16 area. When the underwater cleaning robot is operating, the water flow containing pollutants such as algae enters the interior of the shell 1 from the water inlet 14, and is filtered by the filter layer 15. The algae and other pollutants are blocked by the filter layer 15 and retained in the shell 1. After the filtering and cleaning of the water flow is completed, the water flow flows out of the top of the shell 1.

[0078] The output shaft 37 of the first power unit 31 extends into the first water spraying area 51 and is connected to the first paddle 41, so that the first power unit 31 drives the first paddle 41 to drive water to be sprayed from the water flow filtering channel 16 to the water spraying port 521 of the first water spraying area 51;

[0079] The output shaft 37 of the second power unit 32 extends into the second water spraying area 52 and is connected to the second paddle 42, so that the second power unit 32 drives the second paddle 42 to drive water to be sprayed from the water flow filtering channel 16 to the water spraying port 521 of the second water spraying area 52;

[0080] The first power unit 31 provides driving force for the first blade 41 , and the second power unit 32 provides driving force for the second blade 42 , driving the first blade 41 and the second blade 42 to disturb the flow of water, and the water flows through the water filter channel 16 to complete the filtering and cleaning process.

[0081] A plurality of running wheels 6 are also provided at the bottom of the housing 1 so as to drive the running wheels 6 to move in reverse direction by spraying water.

[0082] The plurality of running wheels 6 may include two, three or more than three. Of course, there is no limitation on the specific number of the running wheels 6. At least three running wheels 6 are helpful to achieve better stability.

[0083] After the water flows into the water spray unit 5 from the top of the shell 1, it is sprayed out from the water spray port 521 of the water spray unit 5, generating a reverse driving force to drive the running wheel 6 to roll, thereby moving the underwater cleaning robot and changing its position.

[0084] Specifically, in some embodiments of the present application, the water spraying direction of the first water spraying area 51 is different from the water spraying direction of the second water spraying area 52, so as to generate thrusts in different directions and change the movable direction of the underwater cleaning robot.

[0085] Furthermore, if Figure 8 and Fig. 9 As shown, the first power unit 31 includes: a first motor 301 and a first transmission assembly 311, and the second power unit 32 includes: a second motor 302 and a second transmission assembly 312;

[0086] The sealed cabin 3 includes an inner cabin 35 and an outer cabin 36, the inner cabin 35 is placed in the outer cabin 36, and the outer cabin 36 is placed in the receiving hole 13;

[0087] The inner cabin 35 is provided with a power supply 33, a first motor 301, a second motor 302 and a main control unit 2;

[0088] A first transmission assembly 311 and a second transmission assembly 312 are disposed in the space formed between the inner cabin 35 and the outer cabin 36;

[0089] The sealed cabin 3 includes a double-layer or multi-layer design of an inner cabin 35 and an outer cabin 36, which can achieve a better sealing effect, and can effectively protect the core components of the underwater cleaning robot such as the power supply 33, the first motor 301, the second motor 302 and the main control unit 2, and has good waterproof and moisture-proof properties, thereby extending the service life of the underwater cleaning robot.

[0090] Specifically, in some embodiments of the present application, the first transmission assembly 311 includes a first gear 321 and a second gear 322 , and the second transmission assembly 312 includes a third gear 323 and a fourth gear 324 ;

[0091] The output end of the first motor 301 extends out of the top of the inner chamber 35 and is connected to the first gear 321. The first gear 321 is connected to the second gear 322. The center of the tooth surface of the second gear 322 is provided with a first output shaft 371 extending out of the outer chamber 36. The first output shaft 371 extends into the first water spraying area 51 and is connected to the first blade 41.

[0092] The output end of the second motor 302 extends out of the top of the inner cabin 35 and is connected to the third gear 323. The third gear 323 is connected to the fourth gear 324. The center of the tooth surface of the fourth gear 324 is provided with a second output shaft 372 extending from the outer cabin 36. The second output shaft 372 extends into the second water spraying area 52 and is connected to the second blade 42.

[0093] The transmission method of the first transmission assembly 311 and the second transmission assembly 312 has high transmission efficiency and reliability, and can improve the underwater propulsion effect of the underwater cleaning robot.

[0094] Furthermore, seals 34 are provided at the connection between the first motor 301 and the inner cabin 35 , the connection between the second motor 302 and the inner cabin 35 , the connection between the first output shaft 371 and the outer cabin 36 , and the connection between the second output shaft 372 and the outer cabin 36 .

[0095] The setting of the seal 34 can fill the gaps at each joint, further improve the sealing effect of the sealed cabin 3, and can effectively prevent water from entering the sealed cabin 3, thereby ensuring the stability and safety of the core components;

[0096] It can also reduce friction and wear between different components, extend the service life of the underwater cleaning robot, prevent damage and failure inside the equipment, and reduce maintenance and repair costs.

[0097] Optionally, in terms of material, the sealing member 34 may be made of metal, rubber, or polytetrafluoroethylene;

[0098] Specifically, in some embodiments of the present application, the seal 34 is a sealing ring made of rubber material. Of course, there is no limitation on the specific material of the seal 34, as long as a good sealing effect can be achieved.

[0099] Furthermore, if Figure 5 , Figure 6 as well as Figure 7 As shown, a water flow baffle 7 is also provided;

[0100] The water flow baffle 7 includes: a first water flow baffle 71 arranged at the water inlet 14, a second water flow baffle 72 arranged at the water outlet 521 of the first water spraying area 51, and a third water flow baffle 73 arranged at the water outlet 521 of the second water spraying area 52;

[0101] The second water flow baffle 72 and the third water flow baffle 73 are both provided with a rotating shaft 701, and the water spray unit 5 is provided with a rotating shaft seat 702 matching the rotating shaft 701; the second water flow baffle 72, the third water flow baffle 73 and the water spray unit 5 are rotatably connected by connecting the rotating shaft 701 with the rotating shaft seat 702;

[0102] A locking portion 703 is provided on the rotating shaft seat 702 to realize the unidirectional opening of the second water flow baffle 72 and the third water flow baffle 73 .

[0103] The setting of the water flow baffle 7 can control the water flow entering or flowing out of the underwater cleaning robot shell 1. The unidirectional opening of the water flow baffle 7 can limit the flow direction of the water flow and prevent the backflow of water from affecting the normal operation of the underwater cleaning robot. The water flow baffle 7 can provide additional damping effect, slow down the flow rate and pressure of the fluid, thereby reducing the impact force of the fluid or avoiding shock.

[0104] When the first paddle 41 and the second paddle 42 are driven, the underwater cleaning robot starts to operate, and the water flow baffles 7 at the water inlet 14 and the water outlet 521 are opened, releasing the closed state of the water inlet 14 and the water outlet 521, so that water can enter from the water inlet 14 and then be sprayed out from the water outlet 521, thereby achieving cleaning and filtration of the water body; when the underwater cleaning robot stops running, the water flow baffle 7 is closed to prevent water backflow, prevent water from entering from the water outlet 521, and prevent pollutants such as algae from flowing out from the water inlet 14.

[0105] Furthermore, if Fig.10 and Fig.11 As shown, the filter layer 15 includes a filter screen 151 and a filter frame 152;

[0106] In addition to removing impurities and pollutants in the water flow, intercepting pollutants and cleaning the water flow, the filter layer 15 can also prevent large particles, impurities and pollutants from entering, avoiding wear, blockage or damage to the underwater cleaning robot; for example, it can avoid wear of the first blade 41 and the second blade 42 by impurities and large particles.

[0107] The shape of the filter frame 152 matches the cross-sectional shape of the internal space of the housing 1; it can filter the incoming water flow as a whole to prevent pollutants from flowing out from the gap between the filter layer 15 and the housing 1;

[0108] The filter screen 151 includes one layer or at least two layers. The filter screen 151 is arranged on a filter frame 152 , and the filter frame 152 is arranged on the housing 1 .

[0109] The filter frame 152 is provided to facilitate evenly disposing the filter screen 151 , thereby achieving a stable connection between the filter screen 151 and the filter frame 152 , and between the filter frame 152 and the housing 1 .

[0110] Furthermore, if Figure 4 and Fig.12 As shown, a cleaning portion 17 is provided on one side or at least on both sides of the edge of the water inlet 14;

[0111] The cleaning part 17 is located at the bottom of the housing 1 and can assist in disturbing the cleaning target when the underwater cleaning robot is cleaning, so that pollutants such as algae enter the water flow filtering channel 16 along with the water to complete filtering and cleaning.

[0112] The cleaning portion 17 is provided with at least two cleaning teeth 171;

[0113] All the cleaning teeth 171 are evenly distributed, and water gaps 172 for water to flow through are formed between adjacent cleaning teeth 171 .

[0114] Providing at least two cleaning teeth 171 can enhance the flexibility of the cleaning portion 17, and the formed water gap 172 facilitates the effective and smooth passage of water when the underwater cleaning robot moves, thereby reducing water flow resistance and not affecting the normal movement of the underwater cleaning robot.

[0115] Furthermore, if Figure 4 As shown, the main control unit 2 includes a waterproof switch 21 sealed to the sealed cabin 3 .

[0116] The waterproof switch 21 is connected to the main board of the main control unit 2 (not shown in the figure), has waterproof performance, can be used normally in a water environment, can effectively prevent liquid from entering the switch, and protect the circuit from damage.

[0117] like Figure 1 As shown, the underwater cleaning robot is also provided with a water sensor 22 for sensing whether the underwater cleaning robot enters the water;

[0118] The water sensor 22 is connected to the main control unit 2 .

[0119] The water sensor 22 is used to cooperate with the waterproof switch 21 to start the first power unit 31 and the second power unit 32 through the main control unit 2 only when the underwater cleaning robot is placed in a water environment, so that the underwater cleaning robot can work normally;

[0120] Underwater cleaning robots are prone to dry running when running without water, which can cause problems such as motor overheating, motor damage, and shortened battery life. By setting up a water sensor 22, the robot can be prevented from running in a waterless state, reducing potential safety risks, improving safety of use, protecting the first motor 301, the second motor 302 and the power supply 3, and extending the service life.

[0121] Furthermore, if Figure 1 As shown, the housing 1 includes an upper shell 11 and a lower shell 12;

[0122] One of the upper shell 11 and the lower shell 12 is provided with a buckle 81 , and the other of the two is provided with a slot 82 ; the upper shell 11 and the lower shell 12 are connected by the buckle 81 engaging with the slot 82 .

[0123] Optionally, the buckle 81 may be provided on the upper shell 11 and the slot 82 may be provided on the lower shell 12, or the slot 82 may be provided on the upper shell 11 and the buckle 81 may be provided on the lower shell 12;

[0124] There is no limitation on the specific configuration of the buckle 81 and the slot 82 .

[0125] In addition to achieving the connection between the upper shell 11 and the lower shell 12, the buckles 81 are evenly arranged on the circumferential surface of the shell 1. When the buckles 81 are unfolded, they can also protect the shell 1. When the shell 1 collides with the outside world, the buckles 81 can play a buffering and shock-absorbing role, protecting the internal part of the underwater cleaning robot from damage.

[0126] Furthermore, the filter layer 15 is provided with a through hole 153 matching the shape of the sealed cabin 3; the accommodating hole 13 is provided in the lower shell 12, and the centers of the upper shell 11, the sealed cabin 3, the filter layer 15 and the lower shell 12 are coaxially arranged.
