Abstract

The utility model relates to a filtering protection mechanism for a base station, a water tank assembly of the base station and the base station. Based on the application, the filtering protection mechanism can be deployed at the top of the sewage containing cavity of the sewage tank of the base station, and the filtering protection mechanism can comprise a closure filtering assembly and a deposition filtering assembly. Wherein the closure filtering assembly can utilize a net surface filtering bag to carry out gas-liquid separation on mixed and injected suction airflow and recycled sewage, and backflow sewage remained in the net surface filtering bag through gas-liquid separation can be filtered and leaked from the net surface filtering bag to a deposition filtering funnel of the deposition filtering assembly; and after being deposited in the deposition filter cone, the sewage is filtered and leaked again from the deposition filter cone, and the solid dirt in the recycled sewage is collected in the filtering protection mechanism through more than one layer of filtering leakage. Therefore, when the sewage tank is cleaned and maintained, the solid-state dirt in the sewage tank can be removed only by cleaning the filtering protection mechanism, so that the cleaning and the maintenance of the sewage tank are simplified.

Please refer to Figure 6 In the embodiment of the present application, the suction mechanism is used to generate a suction air flow (as shown by the continuous hollow dotted arrows in Figure 6 ), and the suction air flow is used to drive the recovered sewage (as shown by the continuous linear dotted arrows in Figure 6 ) in the base sewage discharge pipeline of the base station to flow into the filter protection mechanism 50 from the sewage return hole seat 318.

[0104] Exemplarily, in the embodiment of the present application, the suction air flow and the recovered sewage can be separated after flowing into the filter protection mechanism 50, the suction air flow can be discharged from the exhaust hole seat 317 (i.e. sucked and discharged from the exhaust hole seat 317 by the suction mechanism) after the gas-liquid separation, the recovered sewage can be filtered and seeped towards the bottom of the sewage containing cavity 310 of the sewage tank 31 after the gas-liquid separation, and the solid waste in the recovered sewage can be collected in the filter protection mechanism 50 by the filtration and seepage of the recovered sewage from the filter protection mechanism 50.

[0105] As can be seen above, based on the embodiments of the present application, the water tank assembly can use the suction airflow generated by the suction mechanism to cause the recovered sewage mixed with solid waste in the base sewage discharge pipeline of the base station to be poured into the sewage tank 31; the sewage tank 31 can also be provided with a filtering protection mechanism 50, and the recovered sewage poured into the sewage tank 31 from the base sewage discharge pipeline under the driving of the suction airflow can first be poured into the filtering protection mechanism 50 at the first time of entering the sewage tank 31, so that the solid waste in the recovered sewage can be collected in the filtering protection mechanism 50 through the filtration and leakage of the filtering protection mechanism 50, and is not easy to spread and deposit in the sewage containing cavity 310 of the sewage tank 31. Therefore, when the sewage tank is cleaned and maintained, the solid waste in the sewage tank can be removed only by cleaning the filtering protection mechanism 50, thereby helping to simplify the cleaning and maintenance of the sewage tank.

Figure 8 A structural schematic diagram of the interception filtering assembly of the filtering protection mechanism of the water tank assembly in the embodiments of the present application.

Please refer to Figure 7 to Figure 9 In the embodiments of the present application, the filtering protection mechanism 50 can comprise the interception filtering assembly 52 and the deposition filtering assembly 53.

[0111] Exemplarily, in the embodiments of the present application, the interception filtering assembly 52 can comprise the mesh filter pocket 520, and the mesh filter pocket 520 can shield the nozzle outlet of the backflow nozzle 315 (i.e., located in the flow path of the suction airflow at the top of the sewage containing cavity 310 of the sewage tank 31), so that the mesh filter pocket 520 can be used to receive the recovered sewage (for example, directed to pour through the nozzle outlet of the backflow nozzle 315 from the backflow hole seat 318) from the base sewage discharge pipeline to the sewage containing cavity 310 of the sewage tank 31 under the driving of the suction airflow.

[0112] Exemplarily, in the embodiments of the present application, the deposition filtering assembly 53 can comprise the deposition filter hopper 530, and the deposition filter hopper 530 can be arranged outside the mesh filter pocket 520.

[0113] Exemplarily, in the embodiments of the present application, the deposition filter hopper 530 has a closed hopper bottom, the hopper peripheral wall of the deposition filter hopper 530 has a hopper wall hollowing 535, and further preferably, the hopper wall hollowing 535 can be covered by a mesh.

[0114] Exemplarily, in the embodiments of the present application, the mesh material of the mesh filter pocket 520 and the mesh material covering the hopper wall hollowing 535 are preferably selected to be antibacterial materials, but it can be understood that the embodiments of the present application do not intend to unnecessarily limit the mesh material of the mesh filter pocket 520 and the mesh material covering the hopper wall hollowing 535.

[0115] Exemplarily, in the embodiments of the present application, the suction airflow is used to drive the recovered sewage in the base sewage discharge pipeline of the base station to pour into the mesh filter pocket 520, and the suction airflow and the recovered sewage can be subjected to gas-liquid separation in the mesh filter pocket 520.

[0116] Exemplarily, in the embodiment of the present application, the suctioned air flow can penetrate the deposition filter 530 (for example, penetrate the mesh filter pocket 520) or bypass the deposition filter 530 after the gas-liquid separation of the mesh filter pocket 520, and then be discharged from the exhaust hole seat 317 (i.e., be sucked and discharged from the exhaust hole seat 317 by the suction mechanism).

[0117] Exemplarily, in the embodiment of the present application, the recovered sewage remaining in the mesh filter pocket 520 after the gas-liquid separation can filter and seep into the hopper cavity of the deposition filter 530, and the recovered sewage seeping into the hopper cavity of the deposition filter 530 can further filter and seep out of the deposition filter 530 after the deposition (for example, filter and seep out through the hopper wall hollowing 535), that is, the recovered sewage seeping into the hopper cavity of the deposition filter 530 can further filter and seep into the bottom of the sewage containing cavity 310 after the deposition (for example, filter and seep out through the hopper wall hollowing 535). Thus, the solid pollutants in the recovered sewage are collected in the filter protection mechanism 50 (i.e., in at least one of the mesh filter pocket 520 and the deposition filter 530) through the filter seepage of the mesh filter pocket 520 and the deposition filter 530.

[0118] As can be seen above, based on the embodiment of the present application, the filter protection mechanism 50 can be arranged at the top of the sewage containing cavity 310 of the sewage tank 31 of the base station, and the filter protection mechanism 50 can include the interception filter assembly 52 and the deposition filter assembly 53.
