In some embodiments, referring to fig. 7, the charging device 20 may further include a recharging portion disposed in the main body 210, the recharging portion including a recharging lamp 240, the recharging lamp 240 being configured to emit light to the outside, so that a recharging detection module of the cleaning apparatus, such as an infrared receiver, finds the base station by detecting the light emitted by the recharging lamp 240.

In some embodiments, after the cleaning device is returned to the base station, if the charging portion 220 contacts or is connected to the charging terminal 340 of the cleaning device but the charging detection module 230 of the charging device 20 does not generate the complete machine in-position signal (e.g., within a predetermined time period), the cleaning device may exit the vicinity of the base station, and the complete machine in-position signal may be generated by detecting the light emitted from the recharging light 240 and returning the light to the vicinity of the base station, and so on, until the charging detection module 230 of the charging device 20 can generate the complete machine in-position signal. Thus, when the charging terminal 340 of the cleaning device is ensured to be effectively butted with the charging part 220 of the charging device 20 and the liquid inlet 330 of the cleaning device is accurately butted with the liquid injection pipe 120 of the liquid injection device 10, the charging and/or liquid supplementing of the cleaning device can be restarted. In practice, the back-fill lamp 240 may be, but is not limited to, an LED capable of emitting infrared light.

Referring to fig. 7, 8 and 9, the cleaning liquid supplying apparatus 30 of some embodiments of the present disclosure may include: a cleaning liquid storage part 310, a first detection module, and a charging terminal 340. Wherein, the cleaning liquid storage portion 310 is used for storing the cleaning liquid, the cleaning liquid storage portion 310 has a liquid inlet 330 and a liquid storage space for storing the cleaning liquid, the liquid inlet 330 can have a third position and a fourth position, the liquid inlet 330 allows to inject liquid when being located at the third position, and the liquid inlet 330 does not allow to inject liquid when being located at the fourth position.

For example, the fourth position may be an initial position of the inlet 330, and when the inlet 330 is at the fourth position, which corresponds to a closed state, the inlet 330 is not communicated with the reservoir space, and the liquid cannot be injected. The third position may be a position in the cleaning liquid storage portion 310, and when the inlet port 330 is located at the position, the inlet port 330 is communicated with the liquid storage space, which corresponds to an open state, so that liquid injection can be performed.

In some embodiments, a first detection module may be disposed in the cleaning liquid storage portion 310, and the first detection module may be configured to detect whether the cleaning liquid storage portion 310 needs to be replenished, and generate a replenishment signal when the cleaning liquid storage portion 310 needs to be replenished and provide the replenishment signal to the liquid filling device 10.

In some embodiments, referring to fig. 7, 8 and 9, the cleaning liquid supply device 30 may further include: a liquid inlet position detecting module 320 for generating and sending a third position signal when the liquid inlet of the cleaning liquid storage portion 310 is located at a third position, so that the liquid injecting device 10 can start injecting liquid again when the liquid injecting pipe 120 extends into the interior of the cleaning liquid storage portion 310 and the liquid injecting pipe 120 extends into the cleaning liquid storage portion 310 and the liquid injecting pipe 120 is aligned with the liquid inlet 330 and the position is proper. This prevents liquid leakage and overflow due to an improper position of the liquid pouring spout 120 in the cleaning liquid storage unit 310.

In some embodiments, referring to FIGS. 7, 8 and 9, the loading port position detecting module 320 may comprise a magnet 321 and a detecting element 322, the magnet 321 is disposed near the loading port 330, and the magnet 321 and the detecting element 322 are connected by a spring 323. Here, the detection element 322 may be, but is not limited to, a hall element. When the magnet 321 is pushed toward the detecting element 322 by an external force (e.g., a pushing force provided by the protrusion 122 at the liquid outlet of the liquid injecting tube 120), the spring 323 is compressed, the distance between the magnet 321 and the detecting element 322 is gradually reduced, when the liquid inlet 330 is pushed to the third position, the liquid inlet 330 is communicated with the liquid storage space, and the distance between the magnet 321 and the detecting element 322 is reduced to a critical point, the detecting element 322 generates and sends a signal under the magnetic field of the magnet 321, which is the aforementioned third position signal, at this time, the liquid injecting tube 120, the liquid inlet 330 and the liquid storage space of the cleaning liquid storage portion 310 are communicated, and the cleaning liquid driven by the cleaning liquid providing module and entering the liquid injecting tube 120 can flow into the liquid storage space of the cleaning liquid storage portion 310 through the liquid inlet 330. When the external force pushing the magnet 321 disappears (for example, the cleaning solution providing module stops injecting, the injecting tube 120 starts shrinking, and the protrusion 122 no longer provides pushing force), the spring 323 automatically recovers due to the potential energy, the magnet 321 is pushed to recover to the initial state, and the liquid inlet 330 returns to the fourth position from the third position under the pushing action of the spring 323, and is automatically closed.

The charging terminal 340 may be provided on the housing of the cleaning liquid storage part 310. The charging terminal 340 has a charging contact piece 341, and the charging contact piece 341 is used for providing a pushing force to the charging part 220 after being effectively butted with the charging part 220 of the charging device 20 so that the charging part 220 is integrally moved towards the inside of the main body 210, so that the charging device 20 is triggered to generate a complete machine locating signal.

In some embodiments, referring to fig. 7, 8 and 9, the cleaning liquid supply device 30 may further include: the second detection module is used for detecting whether the cleaning liquid storage part 310 is full, and generating and sending a full signal when the cleaning liquid storage part 310 is full, so that the liquid injection device 10 stops injecting liquid in time.

In some embodiments, referring to fig. 7, 8 and 9, the second detection module 350 may include: one or more probes 351, the one or more probes 351 may be disposed near the loading port 330.

In some embodiments of the present disclosure, the base station may include the foregoing maintenance system, that is, the base station includes the foregoing liquid injection device 10 and the foregoing charging device 20, and the base station may automatically replenish the cleaning device with the cleaning liquid through the liquid injection device 10, and may also charge the cleaning device through the charging device 20. It should be noted that the cleaning liquid may be, but is not limited to, water, detergent, or other liquid having cleaning ability. The present disclosure is not limited as to the type of cleaning liquid.

In some embodiments of the present disclosure, the cleaning system may comprise the aforementioned base station and cleaning device, which may be, for example, a cleaning device comprising the cleaning liquid supply 30, or other cleaning devices, and the cleaning device and the base station may be connected in various ways, such as by wireless communication, wired connection, and the like.

Referring to fig. 7, 8 and 9, after the cleaning device is returned to the vicinity of the base station, if the charging device 20 is effectively connected to the charging terminal 340 of the cleaning device, the liquid injection pipe 120 of the liquid injection device 10 is opposite to the liquid inlet 330 of the cleaning device, which indicates that the cleaning device is completely in place. At this time, if the cleaning liquid needs to be filled into the cleaning liquid storage portion 310 of the cleaning device, the cleaning device may send a liquid filling signal, the liquid filling device 10 may drive the liquid filling pipe 120 to extend into the cleaning liquid storage portion 310 after receiving the liquid filling signal and the complete machine in-position signal from the charging device 20, and may start to fill the liquid when the position of the liquid filling pipe 120 is appropriate (i.e., when the liquid filling pipe 120 is located at the first position and the liquid inlet 330 is located at the third position), the cleaning device may send a full filling signal when the liquid filling is full, and the liquid filling device 10 may stop filling the liquid and withdraw the liquid filling pipe 120 from the cleaning liquid storage portion 310 after receiving the full filling signal.
