[0040] like Figures 1 to 12As shown, a cleaning robot provided by an embodiment of the present application includes: a body 1, a water tank 2, a roller brush mechanism 3 and a squeegee mechanism 4. The body 1 includes a chassis assembly 11 and a water tank shell assembly 12 arranged on the chassis assembly 11, the water tank shell assembly 12 has a receiving groove 121, a sealing ring 122 is arranged on the inner bottom wall of the receiving groove 121, and two opposite limiting rods 123 are arranged in the receiving groove 121; and a water tank 2 is arranged in the receiving groove 121 of the water tank shell assembly 12, the water tank 2 includes a first box body 21 and a handle assembly 22 arranged on the first box body 21, the handle assembly 22 includes two rotating parts 221 arranged opposite to each other and a rotating part 223 arranged with respect to each other. The hand-held portion 222 is connected to two rotating portions 221, and the two rotating portions 221 are rotatably connected to the opposite sides of the first box body 21 respectively. The two rotating portions 221 are respectively provided with clamping grooves 2211, and the clamping grooves 2211 are provided with openings 2212 for the end of the limiting rod 123 to enter the clamping grooves 2211; wherein, when the end of the limiting rod 123 is located in the clamping grooves 2211, the limiting rod 123 abuts against the clamping grooves 2211, so that the bottom of the first box body 21 abuts against the sealing ring 122.

[0041] In the present application, by placing the water tank 2 in the receiving groove 121 of the water tank shell assembly 12, and by rotating the handle assembly 22 so that the opening 2212 of the pressing slide groove 2211 is aligned with the limiting rod 123, the water tank 2 can be lifted out of the receiving groove 121, which is convenient for pouring and adding water. The water tank shell assembly 12 isolates the water tank 2 to achieve dry and wet separation. The handle assembly 22 is rotated so that the limiting rod 123 is located at the end of the pressing slide groove 2211, and the water tank 2 is pressed and limited, so that the first water tank of the water tank 2 is fully abutted against the sealing ring 122 in the receiving groove 121, thereby ensuring the sealing between the water tank 2 and the water tank shell assembly 12, which can effectively avoid water leakage during operation and improve reliability of use.

[0042] like Figure 3 As shown, specifically, a drain port 127 is provided on the inner bottom wall of the receiving tank 121 , and water seeping between the water tank 2 and the receiving tank 121 can be drained through the drain port 127 to avoid residual water in the receiving tank 121 .

[0043] In some embodiments, when the handle assembly 22 is in a vertical state, the end of the limiting rod 123 is located at the opening 2212 of the clamping groove 2211; when the handheld portion 222 of the handle assembly 22 is placed on the first box body 21, the end of the limiting rod 123 is located in the clamping groove 2211.

[0044] In the present application, when the hand-held portion 222 of the handle assembly 22 is placed on the first box body 21, it is in a horizontal state, and the handle assembly 22 can be rotated between a vertical state and a horizontal state. When the water tank 2 needs to be taken out from the receiving groove 121, the handle assembly 22 needs to be rotated to a vertical state first. At this time, the end of the limiting rod 123 is located at the opening 2212 of the pressing chute 2211, and the limiting of the first box body 21 is released, so that the first box body 21 can be smoothly taken out from the receiving groove 121. After the first box body 21 is placed in the receiving groove 121, the handle assembly 22 can be placed on the first box body 21 more stably, and the end of the limiting rod 123 slides in the pressing chute 2211, thereby completing the limiting and downward pressing of the first box body 21, so that the bottom of the first box body 21 is tightly attached to the sealing ring 122, and the sealing between the water tank 2 and the water tank shell assembly 12 is improved.

[0045] like Figure 5 As shown, in some embodiments, a first magnetic member 211 is disposed on the first box body 21, and a second magnetic member 2221 is disposed on the handheld portion 222. When the handheld portion 222 is placed on the first box body 21, the first magnetic member 211 is magnetically connected to the second magnetic member 2221.

[0046] In the present application, the first magnetic component 211 and the second magnetic component 2221 are magnetically attracted together to reinforce the handheld component placed on the first box body 21 to prevent the handheld component from loosening during bumps or collisions with the robot body 1, thereby ensuring the fixing and pressing effects on the water tank 2.

[0047] Specifically, when the handle of the portable assembly is pulled upward, the upward pulling force is greater than the suction force between the first magnetic component 211 and the second magnetic component 2221, thereby separating the first magnetic component 211 from the second magnetic component 2221. When the handle assembly 22 rotates to a vertical state, the locking rod 123 and the clamping groove 2211 are automatically unlocked. When the first box body 21 is placed in the accommodating groove 121, the portable assembly rotates under its own gravity and is placed on the first box body 21. The first magnetic component 211 and the second magnetic component 2221 automatically complete magnetic attraction to achieve self-locking, with a simple structure and easy operation.

[0048] like Figure 4-5 As described, in some embodiments, a water inlet 212 is provided at the top of the first box body 21, a water supply inlet 213 is provided at the bottom of the first box body 21, and a water supply pipe 124 connected to the water supply inlet 213 is provided in the receiving groove 121 of the water tank housing assembly 12; the cleaning robot also includes a roller brush mechanism 3 arranged at the bottom of the chassis assembly 11, and the end of the water supply pipe 124 away from the water supply inlet 213 is connected to the roller brush mechanism 3.

[0049] In the present application, clean water is added to the interior of the first box body 21 through the water inlet 212. After the first box body 21 is placed in the receiving groove 121, the water supply port 213 of the first box body 21 is connected with the water supply pipe 124. The water in the first box body 21 is transported to the roller brush mechanism 3 through the water supply pipe 124, providing moisture to the roller brush mechanism 3, so that the roller brush can clean the ground while sweeping the ground.

[0050] Specifically, a water pump is provided on the water supply pipe 124, and the output end of the water supply pipe 124 is provided at a spray assembly, which is located above the roller brush mechanism 3. The clean water in the first box 21 is pumped to the spray assembly through the water pump to spray the roller brush mechanism 3, wet the roller brush mechanism 3, and clean the ground through the wet roller brush mechanism 3.

[0051] like Figure 6 As shown, in some embodiments, the water tank 2 further includes a second box body 23 disposed in the first box body 21 , and the center of the second box body 23 and the center of the first box body 21 are located on the same vertical line.

[0052] In the related art, the cleaning robot generally includes a clean water tank and a sewage tank, which are respectively provided. When working, the amount of water in the clean water tank continuously decreases, and the amount of water in the sewage tank continuously increases, so that the center of gravity of the clean water tank and the sewage tank as a whole changes. In the embodiment of the present application, by providing the second box body 23 in the first box body 21, and the center of the second box body 23 and the center of the first box body 21 are located on the same vertical line, it is ensured that the center of the first box body 21 and the second box body 23 as a whole will not change significantly during the working process, thereby ensuring the stability of the robot when moving.

[0053] In some embodiments, a water suction pipe 231 and a negative pressure air duct 232 that penetrate the bottom wall of the first box body 21 are provided in the second box body 23, and a water suction port 125 and an air suction port 126 are provided in the receiving groove 121 of the water tank shell assembly 12. The water suction pipe 231 and the negative pressure air duct 232 are connected to the water suction port 125 and the air suction port 126 respectively.

[0054] In the present application, after the water tank 2 is placed in the receiving tank 121, the bottom of the water pumping pipe 231 in the second box body 23 is connected to the water pumping port 125, and the bottom of the negative pressure air duct 232 is connected to the air pumping port 126. The negative pressure air duct 232 is used to pump negative pressure into the second box body 23, so that a negative pressure environment is formed inside the second box body 23, and sewage is pumped into the second box body 23 through the water pumping pipe 231. The connection between the second box body 23 and the air pumping port 126 and the water pumping port 125 can be automatically completed after the water tank 2 is placed in place, which is convenient to operate.

[0055] like Figure 7-8As shown, in some embodiments, the body 1 also includes a column assembly 13 arranged on the chassis assembly 11 and a negative pressure fan 14 arranged on the column assembly 13, and the negative pressure fan 14 is connected to the exhaust port 126; the cleaning robot also includes a squeegee mechanism 4 arranged at the bottom of the chassis assembly 11, and the squeegee mechanism 4 is connected to the exhaust port 125.

[0056] In the present application, the negative pressure fan 14 is connected to the exhaust port 126, and the negative pressure fan 14 draws negative pressure to the interior of the second box body 23 through the exhaust port 126 and the negative pressure air duct 232; the squeegee mechanism 4 is used to clean the sewage on the ground, and the sewage in the squeegee mechanism 4 is sucked into the second box body 23 under the action of negative pressure.

[0057] Specifically, the column assembly 13 serves as a bearing body, the water tank housing assembly 12 is disposed on the column assembly 13 , and a receiving groove 121 for placing the water tank 2 is formed on the body 1 .

[0058] like Figure 9-12 As shown, in some embodiments, the roller brush mechanism 3 includes: a fixed frame 31, connected to the chassis assembly 11; a lifting frame 32, which is arranged on the fixed frame 31 and can move up and down; a driving assembly 33, which is arranged on the fixed frame 31 and is used to drive the lifting frame 32 to move up and down; and a roller brush assembly 34, which is arranged on the lifting frame 32.

[0059] In the present application, the fixed frame 31 is connected to the chassis assembly 11, and the driving assembly 33 can drive the lifting frame 32 to be lifted and lowered, so that the roller brush assembly 34 on the lifting frame 32 can be lifted and lowered. The roller brush assembly 34 can be raised to a certain height and separated from the ground at normal times, and the roller brush assembly 34 can be lowered and abutted against the ground during operation to clean the ground.

[0060] Moreover, as the roller brush assembly 34 is used, the bristles on the roller brush assembly 34 are worn, and the pressure between the roller brush assembly 34 and the ground will become smaller. At this time, the height of the roller brush assembly 34 is adjusted by the driving assembly 33, thereby adjusting the pressure between the roller brush assembly 34 and the ground, ensuring that the roller brush assembly 34 can fully contact the ground and ensure the cleaning effect on the ground.

[0061] Moreover, in different application scenarios, the pressure of the roller brush assembly 34 required for floors of different materials is also different. The height of the roller brush assembly 34 is adjusted by the driving assembly 33, and the pressure between the roller brush assembly 34 and the floor is adjusted according to the material of the floor to ensure the cleaning effect on different floors.

[0062] In some embodiments, the driving assembly 33 includes an elastic connector 331, a clamping cam 332 and a driving motor 333. The lifting frame 32 is connected to the fixed frame 31 through the elastic connector 331. The clamping cam 332 is arranged at the power output end of the driving motor 333. The end face of the clamping cam 332 abuts against the top of the lifting frame 32.

[0063] In the present application, the lifting frame 32 is connected to the fixed frame 31 through an elastic connecting member 331, and the elastic connecting member 331 provides an upward elastic supporting force for the lifting frame 32. The driving motor 333 drives the clamping cam 332 to rotate, and pressure is applied between the clamping cam 332 and the top of the lifting frame 32, thereby controlling the height of the lifting frame 32 and adjusting the height of the roller brush assembly 34.

[0064] In some embodiments, two clamping cams 332 are provided, and a connecting rod 334 is provided between the two clamping cams 332 so that the two clamping cams 332 rotate synchronously, and one of the clamping cams 332 is connected to the power output end of the driving motor 333 .

[0065] In the present application, two clamping cams 332 are rotatably disposed on the fixing frame 31, and the two clamping cams 332 are kept in synchronous rotation by the connecting rod 334, and the two clamping cams 332 are located on the same horizontal plane. The two clamping cams 332 can be driven to rotate synchronously by the driving motor 333 to press down the lifting frame 32, thereby ensuring the stability of the lifting frame 32 when it is lifted or lowered.

[0066] Specifically, two elastic connectors 331 are provided, and the two elastic connectors 331 are respectively located on the outsides of the two clamping cams 332. The elastic connector 331 includes a guide column 3311, a guide sleeve 3312 and a support spring 3313. The guide column 3311 is provided on the top of the fixed frame 31, and the guide sleeve 3312 is slidably provided on the outer peripheral side of the guide column 3311 and can slide in the vertical direction. The guide sleeve 3312 is fixed to the lifting frame 32, and the support spring 3313 is provided between the guide sleeve 3312 and the fixed frame 31, so as to realize elastic support for the lifting frame 32 and ensure that the lifting frame 32 can only move in the vertical direction, thereby ensuring the stability of the lifting frame 32 when it is lifted or lowered.

[0067] In the embodiment of the present application, an armrest assembly 15 is provided on the body 1, and the armrest assembly 15 can be rotatably provided on the body 1 through a damper 151. By adding the damper 151, the armrest assembly 15 can be freely flipped and can stop at a certain angle, providing comfort for people of different heights to push the robot.

[0068] The cleaning robot places the water tank 2 in the receiving groove 121 of the water tank shell assembly 12, and rotates the handle assembly 22 to align the opening 2212 of the pressing groove 2211 with the limiting rod 123, so that the water tank 2 can be lifted out of the receiving groove 121, which is convenient for pouring and adding water. The water tank shell assembly 12 isolates the water tank 2 to separate dry and wet areas. The handle assembly 22 is rotated to make the limiting rod 123 located at the end of the pressing groove 2211, and the water tank 2 is pressed and limited, so that the first water tank of the water tank 2 is fully abutted against the sealing ring 122 in the receiving groove 121, thereby ensuring the sealing between the water tank 2 and the water tank shell assembly 12, which can effectively avoid water leakage during operation and improve reliability in use.
