[0040] Embodiment one

[0041] As Figures 1 to 4 As shown, the embodiment of the present application provides a base 100 arranged on a cleaning base station, mainly used for placing a mop 200 of a cleaning device, so as to facilitate the cleaning of the mop 200 by the cleaning base station. The base 100 comprises a base body 10 and a surrounding plate 21.

[0042] The base body 10 is provided with a containing groove 11 for containing the mop 200 of the cleaning device, and the base body 10 is provided with a clean water inlet 12 and a sewage outlet 13. The surrounding plate 21, at least part of the side wall of the containing groove 11 and at least part of the bottom of the containing groove 11 define a washing groove 20, and a plurality of protruding portions 22 are arranged in the washing groove 20. The mop 200 is in contact with the washing groove 20 and the plurality of protruding portions 22 at the same time.

[0043] The clean water inlet 12 is in communication with the washing groove 20, and the sewage outlet 13 is located outside the washing groove 20 and is lower than the top of the surrounding plate 21, so as to facilitate the discharge of the sewage after washing in the washing groove 20 from the sewage outlet 13.

[0044] Referring to Figure 9 The base 100 provided by the embodiment of the present application can guide the clean water to flow into the washing groove 20 through the clean water inlet 12 when the mop 200 is rotating and washing, the mop 200 is in contact with the washing groove 20, and the mop 200 is also in contact with the protruding portions 22, so that the mop 200 is rubbed while being immersed in water, which is beneficial to the cleaning of the mop 200. At the same time, the sewage outlet 13 is located outside the washing groove 20 and is lower than the top of the surrounding plate 21, so that the sewage rubbed by the protruding portions 22 and the mop 200 flows to the outside of the washing groove 20, preventing the mixing of the sewage and the clean water in the washing groove 20. In this way, the use amount of the clean water can be reduced, and the cleaning effect of the mop 200 can be improved.

[0045] It should be noted that the cleaning device can be a sweeper, a sweeping robot or the like having a sweeping function. Taking the mop 200 of the cleaning device in the shape of a ring as an example, when the mop 200 is washed, the cleaning device rotates the mop 200, the water pump of the cleaning base station delivers clean water to the clean water inlet 12, the clean water flows to the washing groove 20, so that the mop 200 is in contact with the protruding portions 22 of the washing groove 20 and the clean water for rubbing, thereby realizing the cleaning function.

[0046] As Figures 3 to 5 shown, in one embodiment of the present application, the top of the surrounding plate 21 is optionally arranged to be inclined towards the bottom of the containing groove 11 in a direction away from the clean water inlet 12.

[0047] In the embodiment, the top of the surrounding plate 21 is arranged to be inclined to the bottom of the containing groove 11, that is, to the bottom of the washing groove 20, so that the top of the surrounding plate 21 forms a slope, which facilitates the uniform soaking of the mop 200 by the water flow in the washing groove 20, and facilitates the flow of the sewage squeezed out by the friction between the mop 200 and the protruding part 22 from the washing groove 20.

[0048] As shown in Figure 6 and Figure 7 , it should be noted that, optionally, each protruding part 22 is composed of a boss 221 and a plurality of protrusions 222 on the boss 221. Specifically, the boss 221 is arranged to protrude from the bottom of the washing groove 20 to the direction of the opening of the washing groove 20, and the protrusions 222 are arranged to protrude from the top of the boss 221 to the direction away from the top of the boss 221. The top of the boss 221 is arranged to be inclined to the bottom of the containing groove 11, that is, consistent with the inclination direction and angle of the top of the surrounding plate 21. In this way, the washing groove 20 is arranged to be inclined to the bottom of the containing groove 11 as a whole, which is more conducive to the uniform soaking of the mop 200 by the water flow and the discharge of the sewage.

[0049] As shown in Figure 5 , in the above-mentioned embodiments of the present application, specifically, the inclination angle of the top of the surrounding plate 21 is α, which satisfies 8 degrees ≤ α ≤ 17 degrees. The setting of the inclination angle α can facilitate the flow of the water flow and avoid the mop 200 from slipping out of the base 100 when the mop 200 rotates. For example, when the inclination angle α is equal to 8 degrees, when the mop 200 contacts the washing groove 20, the water flow is easy to flow from the direction close to the fresh water inlet 12 to the direction away from the fresh water inlet 12. When the inclination angle α is equal to 17 degrees, the water flow is relatively easier to flow from the direction close to the fresh water inlet 12 to the direction away from the fresh water inlet 12 than when the inclination angle α is equal to 8 degrees. At this time, the inclination angle also avoids the mop 200 from slipping out of the washing groove 20, that is, prevents the mop 200 from slipping out of the base 100.

[0050] It should be noted that the inclination angle of the washing groove 20 is the same as the inclination angle of the mop 200 relative to the horizontal plane on the base 100.

[0051] As shown in Figures 1 to 3 , in an embodiment of the present application, optionally, the washing groove 20 is in a fan-shaped structure, and the longitudinal cross-sectional area of the fan-shaped structure gradually decreases in the direction away from the fresh water inlet 12.

[0052] In the embodiment, the washing groove 20 is in a fan-shaped structure, and the longitudinal cross-sectional area of the fan-shaped structure gradually decreases in the direction away from the fresh water inlet 12. Figure 3It is to be noted that the fan-shaped structure is large at the top and small at the bottom, and the contact area of the annular mop 200 with the washing tank 20 near the water inlet 12 is larger. When the annular mop 200 rotates during washing, for example, when the annular mop 200 rotates counterclockwise, the water flow is long, and the mop 200 is closer to the water at the upper end of the washing tank 20, so the mop 200 is wetter, and the farther the mop 200 is, the cleaner the mop 200 is. This conforms to the washing logic of wetting-wetting-cleaning, so that the mop 200 is continuously rubbed with the protruding part 22 for multiple times of rubbing and washing, and at the same time, the sewage flows out of the washing tank 20 to the sewage outlet 13.

[0053] In addition, in the embodiment in which the washing tank 20 has a fan-shaped structure, the inclination angle of the washing tank 20 is combined. Referring to Figure 3 It is to be noted that the fan-shaped structure is large at the top and small at the bottom, and the contact area of the annular mop 200 with the washing tank 20 near the water inlet 12 is larger. When the annular mop 200 rotates during washing, for example, when the annular mop 200 rotates counterclockwise, the water flow is long, and the mop 200 is closer to the water at the upper end of the washing tank 20, so the mop 200 is wetter, and the farther the mop 200 is, the cleaner the mop 200 is. This conforms to the washing logic of wetting-wetting-cleaning, so that the mop 200 is continuously rubbed with the protruding part 22 for multiple times of rubbing and washing, and at the same time, the sewage flows out of the washing tank 20 to the sewage outlet 13.

[0054] As Figure 8 shown, it is to be noted that a drain pipe 40 can be arranged on the side of the base body 10 opposite the washing tank 20, and at the same time, the drain pipe 40 is connected to the sewage tank, so as to facilitate the collection of sewage.

[0055] In addition, the position of the sewage outlet 13 at the bottom of the containing groove 11 forms a slope around the sewage outlet 13, which facilitates the collection of sewage at the sewage outlet 13. That is, when the sewage flows into the containing groove 11, the bottom of the containing groove 11 is relatively high around the containing groove 11 and low in the middle, so as to ensure that the sewage can flow into the sewage outlet 13 and be discharged from the sewage outlet 13.

[0056] As Figure 2 and Figure 5 shown, in one embodiment of the present application, the water inlet 12 near one side of the washing tank 20 is provided with a plurality of spaced-apart baffles 14, and a gap 141 is formed between two adjacent baffles 14.

[0057] In this embodiment, the plurality of spaced-apart baffles 14 form a row of fences, and the gap 141 between two adjacent baffles 14 is used for the discharge of clean water. In this way, it can be ensured that the clean water can uniformly flow from the gap 141 into the washing tank 20.

[0058] In addition, the water inlet 12 is composed of a water storage tank, and water is supplied to the water storage tank by a water pump, so that the water in the water storage tank flows from the above-mentioned gap 141 to the washing tank 20. The bottom of the water storage tank is a flat surface, which ensures that the clean water discharged from the plurality of gaps 141 is uniform, so as to uniformly soak the mop 200.

[0059] As Figures 5 to 7As shown in the embodiment of the present application, optionally, the accommodating groove 11 is provided with a protruding rib 15, the top of the protruding rib 15 is provided with a plurality of protrusions 151, and the protruding rib 15 is located outside the washing groove 20.

[0060] In the embodiment, taking the washing groove 20 in the form of a ring-shaped mop 200 and a fan-shaped structure as an example, and referring to Figure 3 That is, the protruding rib 15 is located below the washing groove 20, so that the part of the ring-shaped mop 200 not in contact with the washing groove 20 can be in contact with the protruding rib 15, and the protrusions 151 on the protruding rib 15 can be in contact with the mop 200, thereby increasing the overall friction washing area of the mop 200 and improving the cleaning efficiency.

[0061] It should be noted that the protruding rib 15 is in the form of a circular arc, and of course, it can also be in other forms. In addition, referring to Figure 3 and Figure 5 , the protruding rib 15 is high at the top and low at the bottom, that is, the inclination angle of the protruding rib 15 is the same as that of the washing groove 20. At the same time, the structure of the protruding rib 15 is wide at the top and narrow at the bottom. The protrusions 151 on the protruding rib 15 are uniformly distributed on the protruding rib 15.

[0062] As shown in Figure 1 , Figure 3 , Figure 9 and Figure 10 , in an embodiment of the present application, optionally, the washing groove 20 is provided with at least two, and the sewage outlet 13 is located between the adjacent two washing grooves 20.

[0063] In the embodiment, taking two washing grooves 20 as an example, referring to Figure 3 , the left washing groove 20 corresponds to a left water inlet 12, and the right washing groove 20 corresponds to a right water inlet 12.

[0064] In addition, in the embodiment of the protruding rib 15, the left washing groove 20 corresponds to a left protruding rib 15, and the right washing groove 20 corresponds to a right protruding rib 15.

[0065] The two washing grooves 20 can be provided with a cleaning device with two ring-shaped mops 200. Of course, the washing groove 20 can also be provided with three, corresponding to a cleaning device with three ring-shaped mops 200. It can be understood that the number of washing grooves 20 is determined according to the number of ring-shaped mops 200 of the cleaning device, and the number of washing grooves 20 is set according to the number of ring-shaped mops 200.

[0066] As shown in Figure 2 and Figure 5As shown, in one embodiment of this application, optionally, an air outlet 16 is provided on the base body 10, and the air outlet 16 is located between two adjacent washing tanks 20.

[0067] In this embodiment, by setting the air outlet 16, the air blown by the fan of the cleaning base station can be blown out from the air outlet 16, which is beneficial to drying the mop 200 and preventing the mop 200 from growing bacteria due to dampness after cleaning.

[0068] In addition, the height of the air outlet 16 is higher than or equal to the tilt height of the mop 200 on the base 100, so that the air can cover the cross-section of the mop 200, which is more conducive to drying the mop 200.

[0069] like Figure 1 As shown, in one embodiment of this application, optionally, a liquid level detection sensor 30 is provided on the base body 10. The liquid level detection sensor 30 is used to detect the liquid level height of the sewage in the receiving tank 11. The liquid level detection sensor 30 is electrically connected to the control system of the cleaning base station.

[0070] In this embodiment, when the liquid level sensor 30 detects that the sewage level in the receiving tank 11 has reached a preset height, it sends a signal to the control system of the cleaning base station to issue an alarm. The control system then shuts down the cleaning mode and stops the water pump from draining water to the clean water inlet 12. This avoids water overflow caused by a malfunction of the cleaning base station.

[0071] like Figure 2 As shown, in any of the above embodiments, the enclosure 21 includes a first side plate 211, a second side plate 212, and a third side plate 213 connected in sequence. The first side plate 211, the second side plate 212, and the third side plate 213, together with at least a portion of the sidewall of the receiving groove 11 and at least a portion of the bottom of the receiving groove 11, define a washing groove 20. The washing groove 20 has a fan-shaped structure, and the second side plate 212 is an arc-shaped plate, with the corresponding circle outside the washing groove 20.

[0072] In addition, it should be noted that the enclosure 21, the base body 10, and the protrusion 22 are integrally formed. The integral forming of the three facilitates production and increases the structural strength between the three.

[0073] Example 2

[0074] like Figure 9 and Figure 10 As shown, in Embodiment 2 of this application, a cleaning base station is also provided, including the base 100 described in any of Embodiment 1 above.

[0075] The cleaning base station further comprises a water pump for outputting clean water to the clean water inlet 12, a fan for outputting air to the air outlet 16, and a control system for controlling the water pump and the fan to start and stop.

[0076] When the mop 200 is rotating for cleaning on the cleaning base station, the control system controls the water pump to start to output clean water to the clean water inlet 12, so that the clean water flows into the washing tank 20. When the mop 200 is cleaned, the control system controls the water pump to stop, and at this time, the control system controls the fan to start to output air to the air outlet 16, so that the air blows to the mop 200. At this time, the mop 200 is in a rotating state, and the fan continues to output air to the air outlet until the mop 200 is dried. Alternatively, the fan outputs air for a preset time, and the control system controls the fan to stop.

[0077] The cleaning base station has the base 100 described in Embodiment One, and thus has all the beneficial effects of the base 100 described in Embodiment One, which will not be repeated here.

[0078] Embodiment Three

[0079] In Embodiment Three of the present application, a cleaning device is also provided, which comprises the cleaning base station described in any of Embodiment Two.

[0080] The cleaning device can be a robot vacuum cleaner, a dust collector with a sweeping function, a glass surface or wall surface cleaning robot, etc.

[0081] In summary, the present application provides a base 100, a cleaning base station, and a cleaning device. The base body 10 has a containing groove 11 for containing a mop 200 of a cleaning device. The surrounding plate 21, at least a part of the side wall of the containing groove 11, and at least a part of the bottom of the containing groove 11 define a washing tank 20, which is in contact with the mop 200. When the mop 200 is rotating for washing, the clean water inlet 12 guides clean water into the washing tank 20, and the mop 200 is constantly in contact with the protruding part 22, so that the mop 200 is rubbed while being immersed in water, which is beneficial to the cleaning of the mop 200. At the same time, the sewage outlet 13 is located outside the washing tank 20 and is lower than the top of the surrounding plate 21, so that the sewage rubbed out by the protruding part 22 and the mop 200 flows to the outside of the washing tank 20, preventing the mixing of the sewage and the clean water in the washing tank 20, reducing the amount of clean water used, and improving the cleaning effect of the mop 200.

[0082] In the description of the specification, the description of the terms "one embodiment", "some embodiments", "an example", "a specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are contained in at least one embodiment or example of the present application.
