All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present application based on the embodiments herein.

Fig. 1 shows an exploded structure diagram of a base station provided in an embodiment of the present application.

As shown in fig. 1, the embodiment of the present application provides a base station for performing charging and cleaning operations for cleaning robots such as a floor sweeping robot, a floor mopping robot, a floor sweeping and mopping robot, and the like. The floor sweeping robot cleans the floor by adopting a floor sweeping brush, the floor mopping robot cleans the floor by adopting a mop, and the floor sweeping and mopping integrated robot cleans the floor by adopting a mopping piece. For ease of description, the present application will be described with the example of a floor mopping robot.

When the mopping robot moves on the ground, the mop moves along with the equipment main body, and meanwhile, the mop rotates to enable the rotating mop to generate sliding friction with the ground, so that mopping and cleaning of the ground are realized. During the cleaning process of the floor mopping robot, the mop needs to be cleaned frequently to a base station. After being discharged by the drainage pump, the cleaned sewage can be attached with stains such as greasy dirt, floating ash and the like on a tray of the base, and after long-term use, the sewage is easy to become bad and smell and breed bacteria, so that the use experience of a user is affected.

Therefore, the base station that this application embodiment provided through set up in the washing subassembly of base can self-cleaning tray carry out the spot that produces when cleaning operation, effectively prevents to remain the rotten peculiar smell of spot and breeds the bacterium, improves user's use experience.

Specifically, the base station provided in the embodiment of the present application includes a base 1 and a main body 2, a receiving cavity 20 is provided at the bottom of the main body 2, the receiving cavity 20 is also called a "base dock", a water outlet (not shown in the figure) is provided above the receiving cavity 20, and the water outlet is used for being connected to a liquid supply device so as to provide a cleaning liquid for the base station. The base 1 is accommodated in the accommodating chamber 20, and the base 1 includes: chassis assembly 10, tray 11, water intake line (not shown), cleaning assembly 12 and drain 13.

The tray 11 is stacked on the chassis assembly 10 and detachably connected to the chassis assembly 10, and the tray 11 is provided with cleaning ribs 110 for performing a cleaning operation. The washing ribs 110 correspond to the position of, for example, a mop for washing the mop.

One end of the water inlet pipeline is communicated with the water outlet, and the other end of the water inlet pipeline is connected with the tray 11 and is used for introducing cleaning liquid into the tray 11. The cleaning assembly 12 is used to clean the tray 11 from dirt generated when the cleaning operation is performed. One end of the drainage device 13 is connected with the tray 11, and the other end is communicated with the sewage treatment device for draining sewage through negative pressure. Both the sewage after the mop is washed and the sewage after the tray 11 is washed can be discharged to the sewage treatment device through the drainage device 13.

From this, the base station and the base 1 that this application embodiment provided can self-cleaning tray 11 carry out the spot that produces when cleaning operation through setting up in the washing subassembly 12 of base 1, effectively prevents to remain the spot and spoil the peculiar smell and breeds the bacterium, improves user's use experience.

The specific structure of the base 1 provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

FIG. 2 illustrates a top view of a base provided in an embodiment of the present application; fig. 3 shows an exploded structural view of the base shown in fig. 2.

In some embodiments, the tray 11 includes a bottom plate 111 and side plates 112 surrounding a portion of the edge of the bottom plate 111 and symmetrically distributed with respect to a center line of the bottom plate 111 in a width direction, openings are formed between the symmetrically distributed side plates 112, and the cleaning ribs 110 are disposed on the bottom plate 111.

As shown in fig. 2 and 3, the bottom plate 111 is provided with two cleaning ribs 110 distributed at intervals along its width direction, the two cleaning ribs 110 correspond to positions of, for example, a mop, and the cleaning ribs 110 are provided with a plurality of friction columns distributed at intervals, so that the plurality of friction columns can squeeze and rub the mop during the rotation of the mop, and the cleaning effect and the spin-drying effect of the mop are improved. The openings formed between the symmetrically distributed side plates 112 allow the mopping robot to enter the receiving cavity 20 of the main body 2 via the tray 11 and to wash the mopping cloth by means of the washing ribs 110 provided on the bottom plate 111.

In some embodiments, the cleaning assembly 12 includes an ultrasonic generator disposed between the chassis assembly 10 and the base plate 111 and in contact with the base plate 111, and the ultrasonic generator performs impact cleaning of the inner wall of the tray 11 by bubbles generated by high-frequency vibration.

As shown in fig. 3, the ultrasonic generator is disposed between the chassis assembly 10 and the bottom plate 111, specifically, the tray 11 is detachably connected with the chassis assembly 10, the ultrasonic generator may be fixed to the chassis assembly 10 by an adhesive or a screw, and the top of the ultrasonic generator is abutted to the bottom plate 111. The ultrasonic generator generates a signal with a specific frequency by the signal generator, the signal can be a sine signal or a pulse signal, and the frequency of the signal reaches a certain value by the ultrasonic generator. This particular frequency is the frequency of the transducer and is typically used in ultrasonic devices at 20KHz, 28KHz, 40KHz, 60KHz. The frequency signal generated by the signal generator is subjected to impedance matching after passing through the power amplifier, so that the output impedance is consistent with that of the transducer, and the transducer is pushed to convert the electric signal into mechanical vibration, so that the ultrasonic generator can transmit the mechanical vibration to the bottom plate 111 of the tray 11.

The ultrasonic generator must work under the condition of water, after the mop cleaning of the mopping robot is finished, water is stored in the tray 11 of the base 1 or the main body 2 of the base station automatically injects water into the tray 11, the water quantity is different according to the size of the tray 11, and the water quantity is also different, so that the tray 11 can be directly cleaned by utilizing the mop cleaning water. The ultrasonic generator mainly cleans the tray 11 of the base 1, and can also clean the tray 11 together with the floor mopping robot when the tray 11 cleans mopping cloth. Because the base station has no function of detecting stains, the self-cleaning of the base 1 is simple logic, and the self-cleaning of the base 1 is carried out after the mopping robot cleans the mop, or the self-cleaning and the self-cleaning are carried out simultaneously, so that the self-cleaning is not delayed.

The ultrasonic generator performs impact cleaning on the inner wall of the tray 11 through bubbles generated by high-frequency vibration, so that residual stubborn stains or garbage on the inner wall of the tray 11 are separated, and then flow to the drainage device 13 along the water flow direction, and self-cleaning of the base 1 is completed. In order to prevent that dirt of the cleaning mop of the mopping robot may fall off onto the tray 11 and cannot be thoroughly cleaned, the ultrasonic generator is operated for a longer time than the cleaning mop of the mopping robot. Optionally, the vibration frequency of the ultrasonic generator is 50 KHz-70 KHz, and the vibration duration is 10 s-30 s. By this arrangement, it is ensured that stubborn stains adhering to the tray 11 can also fall off.

When the number of the ultrasonic generators is one, the positions of the ultrasonic generators are selected as much as possible from the center position of the tray 11, so that the tray 11 is uniformly vibrated in all directions, and the cleaning effect is good. Alternatively, the number of the ultrasonic generators is at least two, and the at least two ultrasonic generators are symmetrically disposed with respect to the center line of the bottom plate 111. In this way, the tray 11 is subjected to relatively uniform vibration in two symmetrical directions, and the cleaning effect is optimized.

Further, the drain device 13 is disposed opposite to the opening side of the bottom plate 111, and the drain device 13 includes a drain pump 131 and a drain pipe 132 connected between the drain pump 131 and the sewage treatment device. The drain pump 131 may be a centrifugal pump including a rotating impeller and a stationary pump casing. The liquid in the center of the impeller is thrown to the periphery under the action of inertial centrifugal force, and energy is obtained, so that the static pressure energy and the flow velocity of the liquid are increased. After the liquid leaves the impeller and enters the pump shell, the flow passage of the pump shell is gradually enlarged, so that the flow rate of the liquid is reduced, part of kinetic energy is converted into static pressure energy, and then the liquid with higher pressure is conveyed to the sewage treatment device through the water discharge pipe 132 of the pump.

Further, a drain tank 113 and a filter screen assembly 14 detachably mounted on the drain tank 113 are disposed on one side of the tray 11 near the drain device 13, and the filter screen assembly 14 is used for filtering impurities in the sewage. The filter assembly 14 includes a frame and a filter connected to the frame, wherein the filter has a mesh for filtering large particles of dirt. The frame week side of filter screen subassembly 14 is provided with the trip, and the sewage groove 113 corresponds to be provided with trip complex activity knot to make filter screen subassembly 14 detachably install in sewage groove 113, convenient to detach filter screen subassembly 14 and clear up the impurity in the sewage, also can avoid impurity to block up drain pump 131, influence drain pump 131's blowdown function.

In one example, as shown in fig. 3, the sump 113 is formed by recessing the bottom plate 111 toward the chassis assembly 10, and the drain pump 131 and the drain pipe 132 are located at a side of the side plate 112 away from the bottom plate 111. In another example, the sump 113 is disposed at a side of the side plate 112 remote from the bottom plate 111, the drain pump 131 is disposed in the sump 113, and the drain pipe 132 passes through the cover plate 114 covering the sump 113.

The sewage after washing the tray 11 is discharged to the sewage tank 113, and when the liquid at the center of the impeller of the drain pump 131 is thrown to the outer circumference, the center of the impeller generates a low pressure area; since the pressure above the liquid level of the sump 113 is higher than the pressure of the inlet of the drain pump 131, the liquid is sucked into the center of the impeller. Thus, the impeller can continuously suck and discharge liquid through the continuous rotation.

As shown in fig. 1 and 3, the chassis assembly 10 includes a chassis 101 and a baffle plate 102 that is reversible with respect to the chassis 101, the chassis 101 is detachably connected to the tray 11, the baffle plate 102 is located at an opening side of the bottom plate 111, and when the cleaning assembly 12 cleans the tray 11, the baffle plate 102 is turned over and covers the accommodating cavity 20 of the main body 2.

The apron 102 has a slope so that the mopping robot enters the tray 11 by climbing up the slope and then washes the mopping cloth at the washing ribs 110 of the bottom plate 111 of the tray 11. The baffle 102 is provided with a plurality of anti-skidding muscle along width direction's both sides respectively, and a plurality of anti-skidding muscle can prevent to drag ground robot and skid at climbing in-process, further improves climbing ability.

In addition, a rotating shaft is disposed on one side of the chassis 101 corresponding to the opening of the bottom plate 111, and the baffle plate 102 is rotatably connected with the rotating shaft, so that the baffle plate 102 can overturn relative to the chassis 101, and the overturning power can be manually operated by a user or driven by a motor. Thus, when the cleaning assembly 12 cleans the tray 11, the baffle 102 can be turned over relative to the chassis 101 and cover the accommodating cavity 20 of the main body 2, so that cleaning liquid is prevented from splashing outwards to pollute the floor, and user experience is further improved.

Since the bottom plate 111 of the tray 11 is in direct contact with the mop of the mopping robot, most of the dirt after cleaning the mop is concentrated on one side of the bottom plate 111, and the dirt needs to be washed in time by the washing liquid sprayed by the nozzle 121a, so that the dirt is prevented from adhering to the bottom plate 111 to generate peculiar smell and bacteria.

Further, the nozzle assembly 121 further includes a hard tube assembly 121b disposed on a side of the bottom plate 111 facing the chassis assembly 10, and a hose 121c in communication with the hard tube assembly 121b, the hard tube assembly 121b being in communication with the water intake pipe, and an end of the hose 121c remote from the hard tube assembly 121b being in communication with the nozzle 121 a.

In order to prevent the spray assembly 123 from moving due to the large impact force of the water flow when the high-pressure cleaning solution is sprayed, the first and second grooves S1 and S2 are formed on the base plate 111 to accommodate the first and second spray portions 123a and 123b, respectively, and the spray assembly 123 is fixed on the base plate 111 by fastening screws, thereby improving the stability of the spray assembly 123.

In addition, after the spray assembly 123 is assembled with the base plate 111, sealant can be coated at the through holes H3 and the threaded holes H4 to prevent the cleaning liquid from leaking and polluting the surrounding environment such as the floor.

It can be appreciated that the cleaning component 12 in the embodiment of the present application may be any one of the ultrasonic generator, the nozzle component 121, the nozzle component 122, and the spraying component 123, or may be any one of the three, or may be at least two of the three, so that on one hand, the cleaning efficiency and the cleaning effect of the tray 11 may be improved, and on the other hand, when any one of the three is damaged, the tray 11 may be cleaned by other cleaning components 12, which is not repeated.

The technical scheme provided by the embodiment is described below in connection with a specific application scenario.

As shown in fig. 1, a base 1 of the base station is separately arranged from a main body 2 of the base station, a water outlet arranged on the main body 1 is used for being connected with a liquid supply device so as to provide cleaning liquid for the base station, a water inlet pipeline arranged on the base 1 is used for introducing the cleaning liquid into a tray 11, a cleaning component 12 is used for cleaning stains generated when the tray 11 performs cleaning operation, and a water discharge device 13 is used for discharging sewage to a sewage treatment device through negative pressure. The cleaning assembly 12 may be any one of the ultrasonic generator, the combination of the nozzle assembly 121 and the nozzle assembly 122, and the spray assembly 123, or a combination of at least two of the three.

When the mopping robot needs to clean, the mopping robot backs up through the reversible baffle 102 of the base 1 into the accommodating cavity 20 of the main body 2 of the base station, places the mopping cloth on the cleaning ribs 110 of the tray 11, and cleans stains by rotating the mopping cloth. If the cleaning component 12 is an ultrasonic generator, the ultrasonic generator is started while the mop is cleaned, the inner wall of the tray 11 is impacted and cleaned by bubbles generated by high-frequency vibration, and the working time of the ultrasonic generator is longer than that of the mop, so that stains on the tray 11 are thoroughly cleaned.

If the cleaning unit 12 includes a combination of the nozzle unit 121 and the nozzle unit 122, after the mop is cleaned and the mopping robot is separated from the base 1, the high-pressure water flow sprayed through the plurality of nozzles 121a is started to clean the bottom plate 111 of the tray 11, and the cleaning liquid flowing out through the plurality of water spray holes 122c of the nozzle unit 122 is started to clean the side plate of the tray 11.

If the cleaning assembly 12 includes the spraying assembly 123, after the mop is cleaned and the mop robot leaves the base 1, the high-pressure water flow sprayed from the first spraying part 123a starts to clean the part of the tray 11 close to the opening, including the parts close to the bottom plate 111 and the side plate 112 of the opening, and the high-pressure water flow sprayed from the second spraying part 123b cleans the part of the tray 11 far from the opening, including the parts far from the bottom plate 111 and the side plate 112 of the opening.

If the tray 11 is attached with stubborn stains, and the cleaning assembly 12 is a combination of the ultrasonic generator, the nozzle assembly 121 and the nozzle assembly 122, or a combination of any one of the spraying assemblies 123, the ultrasonic generator may be started for a predetermined period of time, the inner wall of the tray 11 may be cleaned by the impact of bubbles generated by the high-frequency vibration, then the bottom plate 111 of the tray 11 may be cleaned by the high-pressure water flow sprayed from the plurality of nozzles 121a, the side plate of the tray 11 may be cleaned by the cleaning liquid sprayed from the plurality of water spray holes 122c of the nozzle assembly 122, or the tray 11 may be cleaned by the high-pressure water flow sprayed from the first spraying portion 123a and the second spraying portion 123b, so that the stubborn stains or the garbage remaining on the inner wall of the tray 11 may be rapidly separated.

During the process of cleaning the tray 11 by the cleaning assembly 12, the baffle 102 can be manually or automatically pushed to turn over relative to the chassis 101 and cover the accommodating cavity 20 of the main body 2, so that cleaning liquid is prevented from splashing outwards to pollute the floor, and user experience is improved.

The dirty marks which are removed after the tray 11 is cleaned flow to the dirty water tank 113 along the water flow direction, the large-particle impurities are filtered by the filter screen of the filter screen assembly 14, then the dirty water is discharged to the sewage treatment device through the drainage pump 131 and the drainage pipe 132, the self-cleaning of the base 1 is completed, and the use experience of a user is improved.

If the filter screen has large-particle impurities after multiple times of cleaning, the filter screen assembly 14 can be detached from the sewage tank 113 to clean the impurities which are not filtered out, and then the filter screen assembly 14 is installed to the sewage tank 113 to improve the cleaning effect of the tray 11. In addition, after long-term use, the base 1 may be damaged, and as the base 1 is detachably connected with the main body 2, the base 1 can be detached from the main body 2 for replacement, so that the use experience of a user is further improved.
