[0035] The following will be described in detail in combination with the accompanying drawings Figures 1-5 The utility model is further described in detail, but not as the limitation of the utility model.

[0036] The embodiment discloses a water spraying device of a sweeping robot, which comprises a shell 1, a sweeping assembly 2 arranged at the bottom of the shell 1, the sweeping assembly 2 being arranged at the center of the bottom of the shell 1, a water spraying assembly 3 arranged at one side of the sweeping assembly 2, and a roller 4 arranged at the bottom of the shell 1 and used for driving the shell 1 to move.

[0037] Specifically, the shell 1 is used for protecting and mounting components inside the sweeping robot, so that the components are not damaged due to external collision, and the components are positioned and prevented from deviating, the sweeping assembly 2 is used for sweeping the ground, the sweeping assembly 2 is arranged at the center of the bottom of the shell 1, so that the sweeping assembly 2 coincides with the moving track of the sweeping robot, and the area moved by the sweeping robot is swept, dust on the ground is scattered in the air during sweeping, the water spraying assembly 3 sprays water on the ground, so that the dust is attached to the ground, and the dust is not scattered in the air when the sweeping assembly 2 sweeps again, and when some stubborn stains adhered to the ground are encountered, the water spraying pressure of the water spraying assembly 3 can be adjusted to flush the stains, so that the stains are separated from the ground, and the cleaning quality of the sweeping robot is improved, and the roller 4 is used for driving the cleaning robot to move, so that the cleaning robot can clean the whole house.

[0038] In some embodiments, the water spraying assembly 3 comprises a spray head 31 and a first driving member 32 connected with the spray head 31, the spray head 31 is rotationally connected with the shell 1, and the output end of the first driving member 32 is connected with the upper part of the spray head 31.

[0039] Specifically, the first driving member 32 is one of an extension air cylinder or an extension motor, the output end of the first driving member 32 is connected with the spray head 31, the middle part of the spray head 31 is rotationally connected with the shell 1, the first driving member 32 drives the upper part of the spray head 31 to move forward or backward, and the lower part of the spray head 31 moves in the opposite direction, so as to change the angle of the spray head 31 with the ground, when the distance between the spray head 31 and the ground is the smallest, the water sprayed by the spray head 31 can contact the ground more quickly, the flying time of the water in the air is short, and the impact force is not greatly lost, so that the impact force of the water is improved, and the stubborn stains on the ground can be flushed; when the distance between the spray head 31 and the ground is large, the flying time of the water in the air is long, and the impact force gradually weakens, so that the impact force of the sprayed water is weak.

[0040] According to actual conditions, the angle of the spray head 31 can be changed by the first driving member 32, so as to achieve the corresponding effect.

[0041] In some embodiments, a plurality of spray heads 31 are arranged along the circumferential arc of the sweeping assembly 2.

[0042] Specifically, the arrangement of the plurality of spray heads 31 can spray water to different positions, thereby effectively avoiding water spraying dead angles and enabling the robotic sweeper to clean more thoroughly. The spray heads 31 are arranged on the side of the cleaning assembly 2 in an arc shape, so that the water sprayed by the water spraying assembly 3 is also distributed in an arc shape. This arrangement, in cooperation with the cleaning assembly 2, does not cause excessive water stains on the ground. If the spray heads 31 are arranged in a plane in a straight line, the spraying range is rectangular, and the cleaning assembly 2 cannot clean the corners of the rectangle, resulting in water stains collecting in the corners. In the embodiment, the spray heads 31 are arranged in an arc shape, which can effectively avoid this situation.

[0043] In the embodiment, the water spraying assembly 3 further comprises a synchronization plate 33, and the plurality of spray heads 31 are connected to the synchronization plate 33. The synchronization plate 33 is connected to the output end of the first driving member 32.

[0044] Specifically, the synchronization plate 33 is connected to the plurality of spray heads 31, and the other side of the synchronization plate 33 is connected to the first driving member 32. The first driving member 32 drives the synchronization plate 33 to move, thereby changing the angle of the plurality of spray heads 31. Therefore, when adjusting the angle of the plurality of spray heads 31, the consistency of the angle of the plurality of spray heads 31 can be ensured, and the consistency of the angle of the spray heads 31 can better control the water output of the spraying.

[0045] In the embodiment, the housing 1 further comprises a water storage assembly 5. The water storage assembly 5 comprises a water storage cup 51 and a water storage cavity 52 arranged in the housing 1. The water storage cup 51 is arranged in the water storage cavity 52, and the water storage cavity 52 is connected to the water spraying assembly 3 through a water supply pipe 53.

[0046] Specifically, the water storage cup 51 is used to store cleaning water or cleaning liquid, and the water storage cavity 52 is used to mount the water storage cup 51. The water storage cavity 52 can limit and fix the water storage cup 51, preventing the center of gravity of the liquid in the water storage cup 51 from changing when the robotic sweeper moves, thereby preventing the liquid from flowing out of the water storage cup 51 and causing damage to the environment.

[0047] In the embodiment, the bottom of the water storage cup 51 is provided with a connector 511, and the water storage cavity 52 is provided with a clearance cavity 521 corresponding to the connector 511. The connector 511 is arranged in the clearance cavity 521.

[0048] Specifically, the liquid in the water storage cup 51 flows out to the outside through the connector 511, and the air avoiding cavity 521 is arranged to facilitate the installation of the connector 511, and the liquid flowing out of the connector 511 in the water storage cup 51 is first stored in the air avoiding cavity 521, and the water delivery pipe 53 is connected with the air avoiding cavity 521 and then transmits the liquid to the spray head 31 to be sprayed out. It needs to be explained that when the water storage cup 51 is installed in the water storage cavity 52, the air avoiding cavity 521 is isolated from the outside, that is, the air avoiding cavity 521 is a sealed space at this time. The sealed air avoiding cavity 521 can prevent air from entering the air avoiding cavity 521, so as to cause the spray head 31 to be unevenly sprayed.

[0049] In the embodiment, the depth of the air avoiding cavity 521 is greater than the length of the connector 511.

[0050] Specifically, the depth of the air avoiding cavity 521 is greater than the length of the connector 511, which can make the connector 511 be more easily installed in the air avoiding cavity 521, and the air avoiding cavity 521 can also accommodate more liquid.

[0051] In the embodiment, the connector 511 includes a first limiting part 512 and a second limiting part 513, the first limiting part 512 is provided with a first through hole 514, the second limiting part 513 has a second through hole 515, and the air avoiding cavity 521 is in communication with the inside of the water storage cup 51 through the first through hole 514 and the second through hole 515.

[0052] Specifically, the first through hole 514 and the second through hole 515 can make the liquid in the water storage cup 51 flow out to the outside.

[0053] In the embodiment, a limiting cavity is arranged between the first limiting part 512 and the second limiting part 513, a sealing member 517 is arranged in the limiting cavity, and the diameter of the sealing member 517 is greater than the diameter of the first through hole 514 and the diameter of the second through hole 515.

[0054] Specifically, the sealing member 517 arranged between the first limiting part 512 and the second limiting part 513 is used to block the connector 511, so that the connector 511 no longer flows out liquid, and the first limiting part 512 and the second limiting part 513 can prevent the sealing member 517 from being out of control of the limiting cavity, so that the sealing member 517 loses the blocking effect. The diameter of the sealing member 517 is greater than the diameter of the first through hole 514 and the diameter of the second through hole 515, which can prevent the sealing member 517 from entering the water storage cup 51 through the first through hole 514 or the sealing member 517 from entering the air avoiding cavity 521 through the second through hole 515, so that the sealing member 517 loses the blocking effect.

[0055] Specifically, after adding liquid into the water storage cup 51, the liquid flows into the connector 511, and the liquid pushes the sealing member 517 towards the second through hole 515, and the sealing member 517 seals the second through hole 515, so that the liquid cannot flow to the outside through the connector 511.

[0056] It should be noted that the through rod 522 is coaxially arranged in the first through hole 514 and the second through hole 515, but the diameter of the through rod 522 is smaller than the diameters of the first through hole 514 and the second through hole 515. Therefore, when the connector 511 is placed in the avoidance cavity 521, the through rod 522 extends into the second through hole 515 to lift the sealing member 517, so that the connector 511 is in a state of communication with the outside. The liquid in the water storage cup 51 flows out to the avoidance cavity 521 through the gap between the second through hole 515 and the through rod 522, and then flows to the spray head 31 through the water delivery pipe 53 to spray the ground.

[0057] After the connector 511 is separated from the avoidance cavity 521, the sealing member 517 loses the support of the through rod 522, and at this time the sealing member 517 is in contact with the second through hole 515, so that the connector 511 is in a state of communication with the outside. When liquid is added to the water storage cup 51, the liquid cannot stay in the connector 511, and the single-flow effect is achieved through the sealing member 517.

[0058] In this embodiment, the cleaning assembly 2 includes a second driving member 21 and a sweeping disc 22. The bottom of the shell 1 is provided with a groove 11 corresponding to the sweeping disc 22. The sweeping disc 22 is arranged in the groove 11. The second driving member 21 is arranged in a region corresponding to the groove 11 inside the shell 1, and the output end of the second driving member 21 penetrates the shell 1 and is connected with the sweeping disc 22.

[0059] Specifically, the second driving member 21 is used to drive the sweeping disc 22 to rotate and clean the ground. The groove 11 is used to mount the sweeping disc 22, so as to prevent the distance between the bottom of the shell 1 and the ground from being too large due to the arrangement of the sweeping disc 22. When the sweeping disc 22 is cleaning, dust splashes everywhere at the bottom of the shell 1. The arrangement of the groove 11 can effectively accommodate the sweeping disc 22, reduce the distance between the bottom of the shell 1 and the ground, and facilitate the installation of the sweeping disc 22. During installation, the sweeping disc 22 only needs to be corresponded with the groove 11.

[0060] In this embodiment, a control assembly and a water pump (not shown in the figure) are further included. The control assembly is electrically connected with the cleaning assembly 2, the watering assembly 3 and the water pump, respectively. The control assembly controls the cleaning assembly 2, the watering assembly 3 and the water pump to work correspondingly. The water pump is arranged at the end of the water delivery pipe 53, and is used to deliver the water in the water storage cup 51 to the spray head 31 through the water delivery pipe 53, so as to realize the watering effect.

[0061] In some cases, the control assembly controls the first driving member 32 to drive the synchronous plate 33 to move, and the movement of the synchronous plate 33 causes the nozzle 31 to be inclined, thereby changing the distance between the water flow and the ground, and realizing corresponding functions and effects.

[0062] In the embodiment, the water storage cover is arranged on the top of the water storage cup 51 and is movably connected with the water storage cup 51, so that the liquid storage amount in the water storage cup 51 can be observed by taking out the water storage cover, and the liquid in the water storage cup 51 can be supplemented.

[0063] In addition, it should be understood that, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the specification is described in this way only for the sake of clarity, and the skilled person should understand the specification as a whole, and the technical solutions in each embodiment can also be combined appropriately to form other embodiments that can be understood by the skilled person.
