In the embodiment of the present invention, after the docking device 200 and the waste liquid collecting device 100 are docked, before the waste liquid in the waste liquid collecting device 100 is emptied, the waste liquid may be sterilized, and the principle thereof is as follows:

when it is necessary to sterilize the waste liquid in the waste liquid collecting apparatus 100 after the docking apparatus 200 and the waste liquid collecting apparatus 100 are docked, the operator selects to perform the sterilization process by when the docking control panel 206 of the docking apparatus 200 or the collection control panel 103 of the waste liquid collecting apparatus 100. After the operator triggers the sterilization procedure, the control module 500 opens the switching valve 422 and closes the drain control valve 432, the switching line 430 opens and connects the inlet fluid path 410 and the outlet fluid path 420, and closes the outlet port 423, and the inlet fluid path 410 and the outlet fluid path 420 form a circulation path for the fluid to circulate.

After the disinfection treatment is finished, liquid discharge operation is executed, and the principle is as follows:

the operator selects to perform the draining operation by the docking control panel 206 of the docking device 200 or the collection control panel 103 of the waste collection device 100. After the operator triggers the draining process, the control module 500 closes the switching valve 422 and opens the draining control valve 432, the switching pipeline 430 closes and closes the input fluid path 410 and the drain fluid path 420, and opens the drain port 423 at the same time, and the input fluid path 410 and the drain fluid path 420 form a circulation path interruption for the circulation of the fluid. The drain pump 423 is activated, and the drain pump 423 sucks the liquid in the waste liquid collection container 109 through the suction joint 212 and discharges the sterilized waste liquid through the discharge port 423.

Referring to fig. 7, fig. 7 is a schematic view of a connection principle of a second embodiment of the waste liquid collecting and treating system provided by the invention. In the embodiment of the present invention, the liquid supply joint 214 is further configured to provide a cleaning function for the waste liquid collecting device 21, or in the embodiment of the present invention, the docking device 22 of the waste liquid collecting and processing system 20 cooperates with the waste liquid collecting device 21 to perform a disinfection process on the waste liquid before the waste liquid collecting device 21 is emptied of the waste liquid, and the flushing liquid path 4101 used for flushing the waste liquid collecting device 21 is reused as the input liquid path 4101 for circular disinfection. Since the rinse solution path 4101 is a technique commonly used in the art, it is not necessary to separately add an input path for waste liquid circulation to the reuse of the rinse solution path 4101, thereby saving space and cost of the apparatus. However, the input fluid path may be added separately under certain requirements. If the aperture of the flushing nozzle connected to the flushing fluid path 4101 is small, in order to prevent the flushing nozzle from being blocked, the flushing nozzle does not enter the waste fluid collecting container 1091 as the waste fluid, and at this time, a separate port for entering the waste fluid needs to be arranged on the waste fluid collecting container 1091, as shown in fig. 7, the input fluid path 4101 is connected to a first input branch 411 and a second input branch 412, wherein the first input branch 411 is provided with a first branch control valve 414, the first branch control valve 414 is used for controlling the connection and disconnection of the first input branch 411, the second input branch 412 is provided with a second branch control valve 415, and the second branch control valve 415 is used for controlling the connection and disconnection of the first input branch 411.

The docking device 22 shown in fig. 7 includes, in addition to the components shown in fig. 5, a tap water inlet 448 and a tap water control valve 447 that controls whether tap water can enter the charging line 4401. Accordingly, the waste liquid collecting and processing system 20 is further provided with a second liquid adding container 442 for storing the cleaning liquid and adding the cleaning liquid to the cleaning liquid path 4101 through the liquid adding line 4401. In order to achieve accurate cleaning solution addition, a second filling pump 444 may be further provided, and is connected to the second filling container 442 and the filling line 4401, respectively, for pumping the cleaning solution in the second filling container 442 into the input liquid path, i.e., the cleaning solution path 4101. The second liquid adding pump 443 can precisely control the adding amount of the cleaning liquid, thereby achieving precise control of the flushing of the waste liquid collecting container 1091. In this embodiment, the second priming container 442 and the second priming pump 444 can be used as external devices to cooperate with the contrast device 22, i.e., via an interface disposed on the priming line 4401, such as the priming interface 207 shown in fig. 4. Optionally, a second refill container 442 and a second refill pump 444 are provided on the docking station 22, i.e., the second refill container 442 and the second refill pump 444 are part of the docking station 22. The docking facility 22 further includes a second check valve 446 disposed on the filling line 4401 for preventing the liquid in the first filling container 441 and the second filling container 442 from flowing back to the tap water interface 448 to pollute the water source.

In the embodiment of the present invention, after the docking device 22 and the waste liquid collecting device 21 are docked, before the waste liquid in the waste liquid collecting device 21 is emptied, the waste liquid may be sterilized, as shown in fig. 7 and 8, according to the following principle:

when it is necessary to sterilize the waste liquid in the waste liquid collecting device 21 after the docking of the docking device 22 and the waste liquid collecting device 21, the operator selects to perform the sterilization process by the docking control panel of the docking device 22 or the collecting control panel of the waste liquid collecting device 21. After the operator triggers the sterilization procedure, the control module 501 opens the switching valve 422 and closes the drain control valve 432, the switching line 430 opens and connects the input fluid path 4101 and the drain fluid path 420, and closes the drain port 423, and the input fluid path 4101 and the drain fluid path 420 form a circulation path through which fluid can circulate. The liquid discharge pump 423 is started, the liquid discharge pump 423 sucks the liquid in the waste liquid collecting container 1091 through the suction connector 212 and injects the sucked liquid into the waste liquid collecting container 1091 through the liquid feeding connector 214, and the control module 501 controls the first liquid adding pump 443 to quantitatively add the disinfectant into the input liquid path 4101 through the liquid adding pipeline 440 according to the waste liquid amount in the waste liquid collecting container 1091. Since the flushing port diameter of the flushing tip is typically small, to prevent clogging of the flushing port, after the disinfection program is initiated, the control module 501 opens the first bypass control valve 414 to communicate with the first input bypass 411 and closes the second bypass control valve 415 to block the second input bypass 412. The disinfecting liquid and the waste liquid entering the input liquid path 4101 are injected into the waste liquid collecting container 1091 through the first input branch 411, and the liquid circulation disinfecting operation is performed according to a predetermined disinfecting program. The liquid circulation can increase the fully mixed disinfection liquid and waste liquid, and enhance the reaction effect of the disinfection liquid and the waste liquid.
