The water outlet 14 may be provided on the side wall where the cleaning tank 11 is connected to the baffle 13, and may be located between the two air guide grooves 121. The water outlet 14 may be a circular through hole.

[0040] In some embodiments, a guide groove 15 is provided at the bottom of the cleaning tank 11. The guide groove 15 can be inclined toward the water outlet 14, which can be used to guide the water in the cleaning tank 11 to the water outlet 14, thereby facilitating the output of the water in the cleaning tank 11.

[0041] In some embodiments, a water spray hole 16 may be provided on the base 10. Specifically, the water spray hole 16 may be provided on the bottom surface of the cleaning tank 11, and it may spray water toward the cleaning tank 11, specifically, it may spray water toward the mop of the sweeping robot. Specifically, in some embodiments, the base 10 is provided with at least one supporting structure 10c at the bottom of the cleaning tank 11, and the supporting structure 10c may play a role in supporting the mop of the sweeping robot.

In some embodiments, the shell 21 may include a front shell 211 and a rear shell 212. The front shell 211 and the rear shell 212 are spliced ​​with each other, and the inner side may define a accommodating chamber 213 for accommodating the drying mechanism 30 and other devices. In some embodiments, an inlet and outlet 2111 may be provided at the lower part of the front shell 211, and the inlet and outlet 2111 may be used for the sweeping robot to enter the cleaning tank 11.

[0045] like Figure 4 and Figure 5 As shown, in some embodiments, the drying mechanism 30 may include a fan 31, an air outlet structure 32 and a heating structure 33. The fan 31 may be arranged in the housing 21 and arranged near the rear housing 212. The outer periphery of the fan 31 may be coated with a soft-gel housing structure, which can be wrapped with the soft-gel housing structure to provide sealing and soft connection. After the fan 31 is started, the entire soft connection is fixed, thereby achieving a shock-absorbing and noise-reducing effect. The air outlet structure 32 may be connected to the fan 31 to blow out the air from the fan 31. The heating structure 33 is arranged in the air outlet structure 32 to heat the airflow generated by the fan 31 so that it forms hot air and is output from the air outlet structure 32 and the air guide groove 121 to the cleaning tank 11.

[0046] Specifically, the air outlet structure 32 can be communicated with the housing structure of the fan 31, and can be connected and fixed with the housing 21 by setting a screw connection structure. In some embodiments, the air outlet structure 32 may include a front cover 321 and a rear cover 322 spliced ​​to each other, and the front cover 321 and the rear cover 322 can be spliced ​​by setting a buckle structure. In some embodiments, a buckle 3211 can be set on the front cover 321, and a buckle 3221 that cooperates with the buckle 3211 can be set on the rear cover 322. In some embodiments, the air outlet structure 32 can be roughly in the shape of a "π", that is, the air outlet structure 32 can include a transversely arranged accommodating portion 32a and two air outlet pipes 32b extending longitudinally toward the base 10. The accommodating portion 32a can accommodate the heating structure 33, and its top can be communicated with the housing structure of the fan 31. The two air outlet pipes 32b are arranged at intervals, and one end is connected to the bottom of the accommodating portion 32a. In some embodiments, at least one first air duct 323 may be formed inside the air outlet structure 32, and there may be two first air ducts 323, which are connected to the two air guide grooves 121 in a one-to-one correspondence. Specifically, each air outlet pipe 32b may form a first air duct 323. The air outlet structure 32 may cover at least part of the opening 1213 of at least one air guide groove 121 and form a second air duct 40. In some embodiments, there may be two second air ducts 40, which are arranged in a one-to-one correspondence with the first air duct 323. Specifically, each air outlet pipe 32b may extend to the opening 1213 of an air guide groove 121, and its front cover 321 may partially extend in the length direction of the air guide groove 121 and cover the opening 1213.

[0047] In some embodiments, the heating structure 33 may be a heater, such as a PTC heater, which may be placed in the accommodating portion 32a, and the heated airflow may be output from the two first air ducts 323 to heat and dry the two mops of the sweeping robot one by one.

[0048] In some embodiments, the base station 100 may further include a pumping device 50, which may include a pumping pipe 51 and a power mechanism (not shown), which is disposed in the housing 21. The pumping pipe 51 may be a hose, one end of which may be connected to the power mechanism (not shown), and the other end may be connected to the water outlet 14, and then connected to the cleaning tank 11. The pumping device 50 may be used to pump out the water in the cleaning tank 11 in a timely manner, thereby preventing the cleaning tank 11 from accumulating water, and preventing the water in the cleaning tank 11 from overflowing into the air guide port 1211.

[0049] In some embodiments, the base station 100 further includes a water level detection device 60, which can be installed in a one-to-one correspondence with the detection window 18 and can be used to detect the water level in the cleaning tank 11. In some embodiments, the water level detection device 60 can be a water level sensor. The power mechanism (not shown) can be turned on or off according to the detection information of the water level detection device 60. Specifically, it can be turned on when the cleaning tank 11 reaches a set water level to pump out the water in the cleaning tank 11. In some embodiments, the set water level can be lower than the position where the cleaning tank 11 connects with the air duct 1211. When the mop of the sweeping robot is cleaned by rotation, that is, water is thrown off for cleaning, when the cleaning water reaches the set water level (that is, it has not yet overflowed the connection between the cleaning tank 11 and the air duct 1211), a power mechanism (not shown) can be triggered, thereby effectively preventing water from overflowing. The cleaning of the mop is completed, and the mop is lifted. At this time, space for air flow movement in the first air duct 323 and the second air duct 40 is formed. At this time, the air-dried mop is received, and the fan 31 and the heating structure 33 are started. The heated airflow follows the first air duct 323 and the second air duct 40 directly to the center of the mop to accelerate the drying of the mop, thereby achieving the effect of cleaning the mop without water overflow or leakage, and heating and drying the mop.

[0050] In some embodiments, the base station 100 also includes a sewage tank (not shown), which can be detachably installed in the housing 20 and can be connected to the pumping device 50. The sewage pumped out by the pumping device 50 can be transported to the sewage tank (not shown) for storage.

[0051] In some embodiments, the base station 100 further includes a water supply device 70, which may be disposed in the housing 21. The water supply device 70 may include a water supply pipe 71 and a clean water tank (not shown); the water supply pipe 71 may be connected to the clean water tank (not shown), and one end of the water supply pipe 71 may be connected to the water spray hole 16, so that the clean water in the clean water tank (not shown) may be output to the water spray hole 16.

[0052] In some embodiments, the base station 100 may further include a filter device 80, which may be disposed in the diversion groove 15 to filter the sewage entering the water outlet 14 to prevent large particles of pollutants from entering the pipeline from the water outlet 14 and clogging the pipeline. In some embodiments, the filter device 80 may include at least one of a filter net and a filter cotton.

[0053] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model.
