The various technical features in the creation of the utility model can be interactively combined without mutual contradiction and conflict.

[0027] With reference to Figures 1 to 4 , an example of the utility model provides a sweeping robot, which comprises a base station 100 and a host computer 200, the base station 100 is provided with an inner cavity 110 for accommodating the host computer 200, and the base station 100 is further provided with a water injection nozzle 120, the water injection nozzle 120 is located on the inner cavity 110, the host computer 200 is provided with a water receiving assembly, the water receiving assembly comprises a water tank 210, a water receiving part 220 connected with the water tank 210, a water receiving hole 221 provided on the water receiving part 220 and a sealing part 230 provided on the water receiving hole 221, the water receiving hole 221 is located on the outer side of the host computer 200, and the water injection nozzle 120 corresponds to the water receiving hole 221.

[0028] When water is added, the host 200 enters the inner cavity 110, the water injection nozzle 120 is inserted into the water receiving hole 221, and the sealing element 230 seals the water injection nozzle 120, so that water leakage during water injection can be prevented, and the sealing performance is improved.

[0029] In some preferred embodiments, the sealing element 230 is an elastic element, and a through hole 231 is formed in the center of the sealing element 230, the diameter of the through hole 231 is smaller than the outer diameter of the water injection nozzle 120, and the through hole 231 allows the water injection nozzle 120 to be inserted.

[0030] It can be understood that during the process of inserting the water injection nozzle 120 into the through hole 231, the through hole 231 is expanded due to the elasticity of the sealing element 230, and the outer periphery of the water injection nozzle 120 is wrapped by the sealing element 230, so that water can be prevented from overflowing from the outer periphery of the water injection nozzle 120.

[0031] Further, the end of the water injection nozzle 120 is provided with a chamfer 121, and when the water injection nozzle 120 is inserted into the through hole 231, the small end of the end of the water injection nozzle 120 enters first, so that the water injection nozzle 120 can be quickly and accurately inserted into the through hole 231.

[0032] In some preferred embodiments, the sealing element 230 is a funnel-shaped structure, and the through hole 231 is located inside the water receiving hole 221.

[0033] It can be understood that after the water injection nozzle 120 is inserted into the through hole 231 of the sealing element 230, the water injection nozzle 120 injects water into the water tank 210 through the water receiving element 220, and the water on the water receiving element 220 will generate pressure on the sealing element 230. The pressure of the water acts on the sealing element 230, so that the sealing element 230 tightly wraps the outer periphery of the water injection nozzle 120, thereby further improving the sealing performance during water injection.

[0034] In some preferred embodiments, the outer side of the host 200 is provided with a first guide groove 240, the first guide groove 240 is a funnel-shaped structure, and the water receiving hole 221 is located at the center of the first guide groove 240.

[0035] It can be understood that during the process of the host 200 entering the inner cavity 110, the first guide groove 240 can guide the water injection nozzle 120 to deviate towards the center of the first guide groove, so that the water injection nozzle 120 can be accurately inserted into the through hole 231 of the sealing element 230.

[0036] In some preferred embodiments, the base station 100 is provided with an elastic seat 130, the water injection nozzle 120 is mounted on the elastic seat 130, and the water injection nozzle 120 is a hard tubular structure.

[0037] Understandably, when the water inlet 120 is offset from the water inlet 221, under the action of the first guide groove 240, the water inlet 120 is offset towards the center of the first guide groove. The elastic seat 130 can provide elastic adjustment for the water inlet 120, and the water inlet 120 will swing at a certain angle, thereby achieving alignment between the end of the water inlet 120 and the through hole 231 of the seal 230.

[0038] In some preferred embodiments, the water inlet 221 is located on the periphery of the main unit 200, and the water inlet 120 is located on the side wall of the inner cavity 110. When the main unit 200 enters the inner cavity 110, the water inlet 120 is directly inserted into the water inlet 221. Thus, the water inlet 120 can be inserted into the water inlet 221 without the need for an additional driving device, thereby reducing manufacturing costs.

[0039] In some preferred embodiments, a second guide groove 250 is also provided on the outer side of the main unit 200. The second guide groove 250 is located on one side of the first guide groove 240. A guide protrusion 140 is provided on the side wall of the inner cavity 110. The guide protrusion 140 is located on one side of the water inlet 120. The guide protrusion 140 corresponds to the second guide groove 250. Specifically, the second guide groove 250 has a bucket-shaped structure, and the guide protrusion 140 has a conical structure.

[0040] It is understandable that when the main unit 200 enters the inner cavity 110, the tapered guide protrusion 140 can guide along the tapered surface of the second guide groove 250, so that the second guide groove 250 and the guide protrusion 140 are aligned, thereby realizing the positioning of the main unit 200 and further improving the positional accuracy of the water inlet 120 and the water inlet hole 221.

[0041] Furthermore, there are two second guide grooves 250, which are symmetrically arranged around the center of the first guide groove 240. There are also two guide protrusions 140, which are symmetrically arranged around the center of the water inlet 120. The two second guide grooves 250 simultaneously guide the two guide protrusions 140, further ensuring that the water inlet 120 on the main unit 200 is aligned with the water inlet hole 221.

[0042] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
