Abstract

The invention relates to a water tank assembly of a base station and the base station. On the basis of the base station, the water tank assembly can utilize the suction airflow generated by the suction mechanism to enable recycled sewage mixed with solid dirt in the base blow-off pipeline of the base station to be poured into the sewage tank; the sewage tank can also be provided with a filtering and protecting mechanism, and the recycled sewage injected into the sewage tank from the blow-off pipeline of the base under the driving of the suction airflow can be injected into the filtering and protecting mechanism at the first time when entering the sewage tank, so that the solid dirt in the recycled sewage is filtered and leaked by the filtering and protecting mechanism through the recycled sewage; the sewage can be collected in the filtering protection mechanism and is not easy to disperse and deposit in the sewage accommodating cavity of the sewage tank. 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.

The clean water tank overflow prevention assembly 18 may be suspended on the clean water liquid level of the clean water stored in the clean water receiving chamber 110, and when the clean water liquid level rises to a preset clean water liquid level threshold height, the clean water tank overflow prevention assembly 18 may block the water inlet hole seat 115.

The clean water tank float 181 can be suspended on the clean water liquid level of the clean water stored in the clean water holding chamber 110. The floating cap plug 183 can be fixedly connected to the clean water tank float 181 through the connecting arm 182, and the floating cap plug 183 can be floated and installed above the water inlet hole seat 115. Among them, the float 181 of the clean water tank rises with the clean water level, which can be converted into pressing down on the floating cap plug 183 through the connecting arm 182; the sinking of the clean water tank float 181 with the clean water level drops can be converted into lifting of the floating cap plug 182 through the connecting arm 182; and, when the clean water level rises to a preset clean water level threshold height, the floating height of the clean water tank float 181 can make the floating cap plug 183 be pressed down to block the water inlet hole seat 115, so as to stop continuing to inject clean water into the clean water containing chamber 110 of the clean water tank 11 when the clean water stored in the clean water containing chamber 110 of the clean water tank 11 is about to be full.

[0147] Exemplarily, in an embodiment of the present application, the water supply hole seat 116 is connected to the clean water holding chamber 110 of the clean water tank 11 through the clean water supply pipe assembly 16, and the water supply hole seat 116 is used to supply the stored clean water in the clean water holding chamber 110 of the clean water tank 11 to the cleaning and maintenance module of the base station.

[0148] Exemplarily, in an embodiment of the present application, the water inlet hole seat 115 can be located at the top of the clean water holding chamber 110 of the clean water tank 11, and the clean water supply pipe assembly 16 can extend to the bottom of the clean water holding chamber 110 of the clean water tank 11, that is, the water supply hole seat 116 is connected to the bottom of the clean water holding chamber 110 of the clean water tank 11 through the clean water supply pipe assembly 16, so that the clean water supply to the water supply hole seat 116 through the clean water supply pipe assembly 16 can be not affected by the clean water storage amount in the clean water holding chamber 110.

[0149] Exemplarily, in an embodiment of the present application, the clean water tank assembly 10 may further include a clean water filter assembly 160, which may be deployed at the bottom of the clean water holding chamber 110 of the clean water tank 11, and the clean water supply pipe assembly 16 extending to the bottom of the clean water holding chamber 110 of the clean water tank 11 may be connected and docked with the clean water filter assembly 160.

[0150] Exemplarily, in an embodiment of the present application, the water supply hole seat 116 supplies clean water to the cleaning and maintenance module of the base station, and may be driven by a driving component (eg, a water pump) disposed in a base assembly of the base station.

[0151] Figure 6 This is a schematic diagram of the deployment of the clean water discharge pipe assembly of the clean water tank of the water tank assembly in the embodiment of the present application. Figure 6In the embodiment of the present application, the clean water tank assembly 10 may further include a clean water discharge pipe assembly 17, which may be arranged below the clean water receiving chamber 110 (for example, the clean water discharge pipe assembly 17 may be arranged in a clean water tank buried pipe base 119 at the bottom of the clean water tank 11), and the clean water discharge pipe assembly 17 may be connected to the bottom of the clean water receiving chamber 110, and the clean water discharge pipe assembly 17 may also be connected to the outside of the clean water tank 11. Thus, when the clean water tank assembly 10 needs to be cleaned and maintained, the clean water stored in the clean water receiving chamber 110 may be quickly discharged by using the clean water discharge pipe assembly 17.

Figure 8 Schematic diagram of the sewage return hole seat of the sewage tank of the water tank assembly in the embodiment of the present application. Figure 7 and Figure 8 In an embodiment of the present application, the sewage tank assembly 30 may include a sewage tank 31, the sewage tank 31 has a sewage holding chamber 310, the sewage holding chamber 310 can be used to hold recycled sewage in the base sewage pipe of the base station, the sewage tank 31 also has a return sewage hole seat 318 and an exhaust hole seat 317, and the return sewage hole seat 318 and the exhaust hole seat 317 are both located at the top of the sewage holding chamber 310.

[0154] Exemplarily, in an embodiment of the present application, the sewage tank 31 may have a top opening, and the sewage tank assembly 30 may further include a sewage tank cover 32, which may be movably installed (e.g., rotatably installed) at the top opening of the sewage tank 31, and the top opening of the sewage tank 31 may be covered by the sewage tank cover 32, and the top of the sewage holding chamber 310 refers to a height range located below the top opening of the sewage tank 31 and adjacent to the top opening of the sewage tank 31.

[0155] Exemplarily, in an embodiment of the present application, the sewage tank 31 may have a first concave side wall 311 and a second concave side wall 312, and the first concave side wall 311 and the second concave side wall 312 may respectively form a recessed space recessed into the interior of the sewage tank 31, and the return hole seat 318 may be suspended above the recessed space formed by the first concave side wall 311 and below the top opening of the sewage tank 31, and the exhaust hole seat 317 may be suspended above the recessed space formed by the second concave side wall 312 and below the top opening of the sewage tank 31, and the top of the sewage holding chamber 310 refers to the height range between the recessed space formed by the first concave side wall 311 or the second concave side wall 312 and the top opening of the sewage tank 31.

[0157] Fig. 9 This is a structural schematic diagram of a sewage tank of a water tank assembly in an embodiment of the present application being equipped with a filtering protection mechanism. Fig.10 Schematic diagram of the internal structure of the sewage tank of the water tank assembly in the embodiment of the present application. Fig. 9 and Fig.10 In an embodiment of the present application, the sewage tank assembly 30 may further include a filter protection mechanism 50, which is located at the top of the sewage holding chamber 310 of the sewage tank, and the return sewage hole seat 318 may be connected to the sewage holding chamber 310 of the sewage tank through the filter protection mechanism 50.

[0158] Fig.11 This is a schematic diagram of the sewage recovery principle of the sewage tank of the water tank assembly in the embodiment of the present application. Fig.11 In the embodiment of the present application, the suction mechanism is used to generate a suction airflow (such as Fig.11 In addition, the suction airflow is used to drive the recycled sewage in the base sewage pipeline of the base station (such as Fig.11 The filter protection mechanism 50 is poured into the sewage return hole seat 318 (as shown by the continuously extending linear dotted arrow).

[0159] Illustratively, in an embodiment of the present application, gas-liquid separation may occur between the suction airflow and the recovered sewage after they are poured into the filter protection mechanism 50; the suction airflow may be discharged from the exhaust hole seat 317 after gas-liquid separation (i.e., it is sucked and discharged from the exhaust hole seat 317 by the suction mechanism); and the recovered sewage may be filtered and leaked toward the bottom of the sewage holding chamber 310 of the sewage tank 31 after gas-liquid separation; and solid impurities in the recovered sewage may be collected in the filter protection mechanism 50 through the filtered leakage of the recovered sewage from the filter protection mechanism 50.

[0160] As can be seen above, based on the embodiment of the present application, the water tank assembly can use the suction airflow generated by the suction mechanism to allow the recycled sewage mixed with solid dirt in the base sewage pipeline of the base station to be poured into the sewage tank 31; the sewage tank 31 can also be equipped with a filtering protection mechanism 50, and the recycled sewage poured from the base sewage pipeline into the sewage tank 31 driven by the suction airflow can be poured into the filtering protection mechanism 50 at the first time of entering the sewage tank 31, so that the solid dirt in the recycled sewage can be collected in the filtering protection mechanism 50 after the recycled sewage is filtered and leaked in the filtering protection mechanism 50, and is not easy to be scattered and deposited in the sewage holding chamber 310 of the sewage tank 31. Therefore, when cleaning and maintaining the sewage tank, it is only necessary to clean the filtering protection mechanism 50 to achieve the removal of solid dirt in the sewage tank 31, which helps to simplify the cleaning and maintenance of the sewage tank 31.

[0161] Exemplarily, in an embodiment of the present application, the sewage tank 31 may also have a return sewage nozzle 315, the return sewage nozzle 315 may be fixed to the return sewage hole seat 318 (for example, fixed above the return sewage hole seat 318), the return sewage nozzle 315 may be integrated with the return sewage hole seat 318, the return sewage nozzle 315 may be connected to the return sewage hole seat 318, the filter protection mechanism 50 may be installed on the return sewage nozzle 315, and the suction airflow is used to drive the recovered sewage in the base sewage pipeline of the base station, and directionally inject it into the filter protection mechanism 50 from the return sewage hole seat 318 through the nozzle outlet of the return sewage nozzle 315.

[0162] Illustratively, in an embodiment of the present application, the nozzle outlet of the sewage return nozzle 315 is oriented toward the exhaust hole seat 317 in the horizontal direction, so that the flow of the suction airflow is smoother, thereby making the suction airflow have a stronger driving ability for recycling sewage.

[0163] For example, in the embodiment of the present application, the filter protection mechanism 50 may further include a filter assembly (such as an interception filter assembly 52 and a sediment filter assembly 53), and a sewage return butt joint 51, the sewage return butt joint 51 may be connected to the filter assembly of the filter protection mechanism 50, the sewage return butt joint 51 may be buckled on the sewage return nozzle 315, and the filter assembly of the filter protection mechanism 50 may block the nozzle outlet of the sewage return nozzle 315 (i.e., located in the flow path of the suction airflow at the top of the sewage receiving chamber 310 of the sewage tank 31). That is, the sewage return butt joint 51 may be used to achieve pipeline docking between the filter protection mechanism 50 and the base sewage discharge pipeline of the base station.

[0164] Exemplarily, in an embodiment of the present application, the filter protection mechanism 50 includes at least two filter components (e.g., an intercepting filter component 52 and a sedimentation filter component 53), the at least two filter components are stacked, and at least one of the at least two filter components can block the nozzle outlet of the return sewage nozzle 315 (i.e., located in the flow path of the suction airflow at the top of the sewage holding chamber 310 of the sewage tank 31).

[0165] Fig.12 It is a structural schematic diagram of the filtering protection mechanism of the water tank assembly in the embodiment of the present application. Fig.13 It is a structural schematic diagram of the intercepting filter assembly of the filter protection mechanism of the water tank assembly in the embodiment of the present application. Fig.14 This is a schematic diagram of the structure of the sediment filter assembly of the filter protection mechanism of the water tank assembly in the embodiment of the present application. Figure 12 to Figure 14 In an embodiment of the present application, the filter protection mechanism 50 may include a interception filter component 52 and a sedimentation filter component 53 .

[0166] Exemplarily, in an embodiment of the present application, the intercepting filter assembly 52 may include a mesh filter bag 520, and the mesh filter bag 520 may block the nozzle outlet of the return sewage nozzle 315 (i.e., located in the flow path of the suction airflow at the top of the sewage holding chamber 310 of the sewage tank 31), so that the mesh filter bag 520 can be used to receive the recycled sewage that is injected from the base sewage pipe of the base station into the sewage holding chamber 310 of the sewage tank 31 under the drive of the suction airflow (for example, directionally injected from the return sewage hole seat 318 through the nozzle outlet of the return sewage nozzle 315).

[0167] For example, in an embodiment of the present application, the sediment filter assembly 53 may include a sediment filter 530 , and the sediment filter 530 may be disposed on the outer layer of the mesh filter bag 520 .

[0168] Illustratively, in an embodiment of the present application, the sedimentation filter 530 has a closed bottom, and the filter hopper circumferential wall of the sedimentation filter 530 has a hopper wall hollowing 535 , and further preferably, the hopper wall hollowing 535 may be covered by a mesh.

[0169] For example, in the embodiment of the present application, the mesh material of the mesh filter bag 520 and the mesh material covering the bucket wall hollow 535 can be selected from breathable materials that allow solution penetration. Preferably, the mesh material of the mesh filter bag 520 and the mesh material covering the bucket wall hollow 535 can further have antibacterial properties. It can be understood that the explanation of the mesh material herein is intended to indicate that the mesh can allow the suction airflow and the recycled sewage that does not contain solid waste to pass through, and it is not intended to make other unnecessary restrictions on the mesh material of the mesh filter bag 520 and the mesh material covering the bucket wall hollow 535.

[0170] Illustratively, in an embodiment of the present application, the suction airflow is used to drive the recycled sewage in the base sewage pipe of the base station to be poured into the mesh filter bag 520, and the suction airflow and the recycled sewage can be separated into gas and liquid in the mesh filter bag 520.

[0171] Exemplarily, in an embodiment of the present application, after the suction air flows through the mesh filter bag 520 for gas-liquid separation, it can penetrate the sedimentation filter bag 530 (for example, penetrate the mesh filter bag 520) or bypass the sedimentation filter bag 530 and be discharged from the exhaust hole seat 317 (that is, it is sucked out from the exhaust hole seat 317 by the suction mechanism).

[0172] For example, in the embodiment of the present application, the recycled sewage remaining in the mesh filter bag 520 after gas-liquid separation can be filtered and leaked to the bucket cavity of the sediment filter bucket 530, and the recycled sewage leaking into the bucket cavity of the sediment filter bucket 530 can be filtered and leaked to the outside of the sediment filter bucket 530 after sedimentation (for example, filtered and leaked through the bucket wall hollow 535), that is, the recycled sewage leaking into the bucket cavity of the sediment filter bucket 530 can be filtered and leaked to the bottom of the sewage holding chamber 310 after sedimentation (for example, filtered and leaked through the bucket wall hollow 535). Thus, the solid dirt in the recycled sewage is collected in the filter protection mechanism 50 (that is, at least one of the mesh filter bag 520 and the sediment filter bucket 530) through filtering and leaking in the mesh filter bag 520 and the sediment filter bucket 530.

[0173] As can be seen above, based on the embodiment of the present application, the filter protection mechanism 50 can be deployed on the top of the sewage holding chamber 310 of the sewage tank 31 of the base station, and the filter protection mechanism 50 can include an interception filter assembly 52 and a sedimentation filter assembly 53. Among them, the interception filter assembly 52 can use the mesh filter bag 520 to perform gas-liquid separation on the mixed suction airflow and the recovered sewage, and the return sewage retained in the mesh filter bag 520 after gas-liquid separation can first be filtered and leaked from the mesh filter bag 520 to the sedimentation filter bucket 530 of the sedimentation filter assembly 53, and then filtered and leaked again from the sedimentation filter bucket 530 after sedimentation in the sedimentation filter bucket 530, and the solid dirt in the recovered sewage is efficiently collected in the filter protection mechanism 50 through more than one layer of filtering and leakage. Therefore, when cleaning and maintaining the sewage tank, it is only necessary to clean the filter protection mechanism 50 to achieve the removal of solid dirt in the sewage tank 31, thereby helping to simplify the cleaning and maintenance of the sewage tank 31.

[0174] For example, in the embodiment of the present application, the top of the filter bucket peripheral wall of the sedimentation filter bucket 530 may have a sewage pouring opening 533 , and the bucket wall hollowing 535 of the filter bucket peripheral wall of the sedimentation filter bucket 530 may be located below the sewage pouring opening 533 .

[0175] For example, in an embodiment of the present application, if the top of the filter bucket peripheral wall of the sediment filter bucket 530 may have a sewage injection opening 533, then the opening of the mesh filter bag 520 may be connected to the sewage injection opening 533, and the mesh filter bag 520 may be suspended on the top of the bucket cavity of the sediment filter bucket 530. In this case, the suction airflow may drive the recycled sewage in the base sewage pipeline of the base station to be injected into the mesh filter bag 520 from the sewage injection opening 533.

[0176] Exemplarily, in an embodiment of the present application, if the top of the filter bucket peripheral wall of the sedimentation filter bucket 530 can have a sewage filling opening 533, and, as described above, the filter protection mechanism 50 can also include a return sewage docking connector 51, then the return sewage docking connector 51 can be fixed to the outside of the filter bucket peripheral wall of the sedimentation filter bucket 530 (for example, integrally formed on the outside of the filter bucket peripheral wall of the sedimentation filter bucket 530), and the return sewage docking connector 51 can be connected to the sewage filling opening 533.

[0177] Exemplarily, in an embodiment of the present application, if the sewage tank 31 can also have a return sewage nozzle 315 as described above, and the return sewage docking joint 51 can be buckled on the return sewage nozzle 315, then, when the return sewage docking joint 51 is buckled on the return sewage nozzle 315, the sewage filling opening 533 can be aligned with the nozzle outlet of the return sewage nozzle 315, and the suction airflow is used to drive the recovered sewage in the base sewage pipeline of the base station to be directionally poured from the return sewage hole seat 318 through the return sewage nozzle 315 and the sewage filling opening 533 into the mesh filter bag 520 of the filter protection mechanism 50.

[0178] Exemplarily, in an embodiment of the present application, the intercepting filter assembly 52 of the filtering protection mechanism 50 may further include a pocket opening docking plate 521, the pocket opening docking plate 521 having a through hole, the pocket of the mesh filter bag 520 is fixed to the edge of the through hole of the pocket opening docking plate 521, the pocket opening docking plate 521 abuts against the inner side of the filter bucket peripheral wall of the sedimentation filter bucket 530, and the through hole of the pocket opening docking plate 521 is aligned with the sewage filling opening 533, so that the pocket of the mesh filter bag 520 is docked with the sewage filling opening 533.

[0179] Illustratively, in an embodiment of the present application, the intercepting filter assembly 52 of the filtering protection mechanism 50 may further include a bag body support frame 522, which is fixedly connected to the bag mouth docking plate 521, and the bag body support frame 522 extends into the mesh filter bag 520, and the mesh filter bag 520 is supported and extended by the bag body support frame 522. For example, the extension direction of the bag body support frame 522 can be supported to be in the same direction as the flow direction of the suction airflow.

[0180] For example, in an embodiment of the present application, the sedimentation filter 530 may have an extension channel 531, which may protrude outward from the top of the chamber of the sedimentation filter 530, and the extension channel 531 may be connected to the chamber of the sedimentation filter 530. The filter hopper peripheral wall of the sedimentation filter 530 may include channel side walls located on both sides of the extension channel 531 and channel end walls located at the protruding ends of the extension channel 531, and the sewage injection opening 533 is opened in the channel end wall of the extension channel 531. In this case, the sewage return butt joint 51 may be fixed to the outer side of the channel end wall of the extension channel 531 (for example, integrally formed on the outer side of the channel end wall of the extension channel 531), and the pocket butt joint plate 521 may abut the inner side of the channel end wall of the extension channel 531.

[0181] For example, in the embodiment of the present application, on the one hand, the mesh filter bag 520 of the interception filter assembly 52 can provide a nearly fully enclosed storage space for solid waste, while the sedimentation filter hopper 530 of the sedimentation filter assembly 53 can provide a semi-enclosed storage space with a top opening, so the mesh filter bag 520 of the interception filter assembly 52 is more difficult to clean than the sedimentation filter hopper 530 of the sedimentation filter assembly 53; on the other hand, most of the material of the interception filter assembly 52 is the mesh filter bag 520, and the sedimentation filter hopper 530 of the sedimentation filter assembly 53 can be an integral injection molded part of a hard material such as plastic, in which case the cost of the mesh filter bag 520 can be lower than that of the sedimentation filter hopper 530. Therefore, the interception filter assembly 52, which is relatively difficult to clean and relatively low in cost, can be configured as a replaceable component, and the sedimentation filter assembly 53 can be configured as a sustainable component.

[0182] Exemplarily, in an embodiment of the present application, if the sedimentation filter bucket 530 has an extended channel 531, then, in order to facilitate the replaceable and disassembly of the intercepting filter assembly 52, the inner side of the channel side wall of the extended channel 531 may have a limiting flange 532, and an insertion gap may be left between the limiting flange 532 and the channel end wall of the extended channel 531, and the pocket docking plate 521 may be inserted into the insertion gap between the limiting flange 532 and the channel end wall of the extended channel 531, and the pocket docking plate 521 may be limited by the limiting flange 532 in the insertion gap to abut the channel end wall of the extended channel 531.

[0183] Exemplarily, in an embodiment of the present application, if the sedimentation filter 530 has an extension channel 531, then, in order to facilitate the replaceable and disassembly of the interception filter assembly 52, the upper edge of the channel end wall of the extension channel 531 may have a mounting buckle 537, and the interception filter assembly 52 of the filtering protection mechanism 50 may also include a mounting protrusion 525, and the mounting protrusion 525 is fixedly connected to the pocket docking plate 521, and the mounting protrusion 525 may be a protrusion clamping hole 526, and the mounting protrusion 525 can utilize the protrusion clamping hole 526 to clamp with the mounting buckle 537 to achieve a detachable fixed connection with the channel end wall of the extension channel 531.

[0184] For example, in the embodiment of the present application, in order to facilitate the installation operation of engaging the lug locking hole 526 with the installation buckle 537, the upper edge of the channel end wall of the extension channel 531 may have a positioning notch 536, the notch width of the positioning notch 536 is adapted to the lug width of the installation lug 525, and the installation buckle 537 may be located in the positioning notch 536. Therefore, when the installation lug 525 is pressed against the upper edge of the channel end wall of the extension channel 531, the installation lug 525 may slide into the positioning notch 536, and may be guided by the positioning notch 536 so that the lug locking hole 526 and the installation buckle 537 are positioned and aligned.

[0185] Exemplarily, in an embodiment of the present application, in order to facilitate the disassembly operation of disengaging the protrusion locking hole 526 from the mounting buckle 537, the mounting protrusion 525 may also have a redundant tail 527, and the redundant tail 527 may be in a free state that can be pulled when the protrusion locking hole 526 and the mounting buckle 537 are engaged.

[0186] For example, in the embodiment of the present application, as described above, the sewage tank 31 has a top opening, the sewage receiving chamber 310 is located below the top opening of the sewage tank 31, the sewage tank cover 32 is used to cover the top opening of the sewage tank 31, and the filter protection mechanism 50 can be freely disassembled from the top opening of the sewage tank 31 when the sewage tank cover 32 is opened. For example, the filter protection mechanism 50 can be freely disassembled from the top opening of the sewage tank 31 by buckling or disassembling the return sewage nozzle 315 through the return sewage butt joint 51.

[0187] Exemplarily, in an embodiment of the present application, the filtering protection mechanism 50 is used to prevent solid dirt in the recycled sewage from spreading in the sewage holding chamber 310 of the sewage tank 31. Therefore, the sewage tank 31 should be allowed to receive recycled sewage from the base sewage pipeline of the base station when the filtering protection mechanism 50 is installed.

[0188] Fig.15 This is a schematic diagram of the structure of the sewage tank of the water tank assembly in the embodiment of the present application equipped with a tank cover interference assembly. Fig.15 In an embodiment of the present application, in order to check whether the sewage tank 31 is equipped with a filter protection mechanism 50 , the sewage tank assembly 30 may further include a tank cover interference assembly 35 , and the tank cover interference assembly 35 may be movably installed at the top opening of the sewage tank 31 .

[0189] Fig.16 This is a schematic diagram of the structure in which the tank cover interference component of the water tank assembly in the embodiment of the present application forms an interference barrier with the sewage tank cover. Fig.16 In an embodiment of the present application, when the filter protection mechanism 50 is removed from the sewage holding chamber 310, the box cover interference assembly 35 can be reset to the default first position. When the box cover interference assembly 35 is in the first position, it generates an interference stop on the sewage tank cover 32, and the interference stop of the box cover interference assembly 35 on the sewage tank cover 32 is used to prevent the sewage tank cover 32 from sealing the top opening of the sewage tank 31.

[0190] Fig.17 This is a schematic diagram of the structure in which the interference component of the water tank cover of the water tank assembly in the embodiment of the present application is removed from the interference block by the filter protection mechanism. Fig.17 In an embodiment of the present application, when the filter protection mechanism 50 is installed at the top of the sewage holding chamber 310 at the top opening of the sewage tank 31 (for example, the return sewage docking connector 51 of the filter protection mechanism 50 is buckled on the return sewage nozzle 315), the tank cover interference assembly 35 can be pushed into the second position by the filter protection mechanism 50, and the tank cover interference assembly 35 cancels the interference stop on the sewage tank cover 32 when it is in the second position.

[0191] Exemplarily, in an embodiment of the present application, the lower surface of the sewage tank cover 32 facing the sewage tank 31 may have a cover boss 326, and when the sewage tank cover 32 seals the top opening of the sewage tank 31, the cover boss 326 may extend into a calibrated position at the top opening of the sewage tank 31.

[0192] For example, in the embodiment of the present application, if the lower surface of the sewage tank cover 32 facing the sewage tank 31 has a cover boss 326, then, Fig.16 As shown, when the filter protection mechanism 50 is taken out from the sewage holding chamber 310, the box cover interference assembly 35 can be reset to the default first posture. When in the first posture, the box cover interference assembly 35 occupies the calibrated position of the box cover boss 326 at the top opening of the sewage tank 31 to generate an interference stop for the sewage tank cover 32, and the interference stop of the box cover interference assembly 35 on the sewage tank cover 32 is used to prevent the sewage tank cover 32 from sealing the top opening of the sewage tank 31.

[0193] For example, in the embodiment of the application, if the lower surface of the sewage tank cover 32 facing the sewage tank 31 has a cover boss 326, then, Fig.17 As shown, when the filter protection mechanism 50 is installed on the top of the sewage holding chamber 310 at the top opening of the sewage tank 31 (for example, the return sewage docking joint 51 of the filter protection mechanism 50 is buckled on the return sewage nozzle 315), the tank cover interference assembly 35 can be pushed into the second position by the filter protection mechanism 50, and the tank cover interference assembly 35 avoids the calibrated position of the tank cover boss 326 at the top opening of the sewage tank 31 when in the second position to cancel the interference stop on the sewage tank cover 32.

[0194] Exemplarily, in an embodiment of the present application, the filter protection mechanism 50 may further include an interference release cantilever 56, and when the filter protection mechanism 50 is installed at the top of the sewage holding chamber 310 at the top opening of the sewage tank 31, the box cover interference assembly 35 may be pushed into the second position by the interference release cantilever 56.

[0195] For example, in an embodiment of the present application, the tank cover interference assembly 35 may include a swinging pry bar 351, which may be rotatably mounted on the top opening of the sewage tank 31, and the swinging pry bar 351 has a pry bar tail 352 and a limit end 353 at opposite ends of the rotating shaft, respectively, and the first posture and the second posture of the tank cover interference assembly 35 may refer to the swinging posture of the swinging pry bar 351. In this case:

[0196] When the filter protection mechanism 50 is taken out from the sewage receiving chamber 310, Fig.16As shown, the pry bar tail 352 can be in a free state, and the swing pry bar 351 can be reset and swung to the first position when the pry bar tail 352 is in a free state, and the limit end 353 occupies the marked position of the box cover boss 326 at the top opening of the sewage tank 31 when the box cover interference assembly 35 is in the first position, so as to generate the interference stop described above for the sewage tank box cover 32;

[0197] When the filter protection mechanism 50 is installed at the top opening of the sewage tank 31 on the top of the sewage receiving chamber 310 (for example, the sewage return pipe joint 51 of the filter protection mechanism 50 is buckled on the sewage return nozzle 315), as shown in FIG. Fig.17 As shown, the interference release cantilever 56 presses the pry bar tail 352, and the swing pry bar 351 swings to the second posture through the pressure of the interference release cantilever 56 on the pry bar tail 352, and the limit end 353 avoids the calibrated position of the box cover boss 326 at the top opening of the sewage tank 31 when the swing pry bar 351 is in the second posture to cancel the interference stop on the sewage tank cover 32.

[0198] For example, in the embodiment of the present application, if the mesh filter bag 520 of the intercepting filter assembly 52 needs to be installed on the sediment filter bucket 530 of the sediment filter assembly 53 through the bag opening docking plate 521, and the installation of the filter protection mechanism 50 in the sewage tank 31 depends on the return sewage docking pipe joint 51 fixedly connected to the sediment filter bucket 530, then the interference release cantilever 56 can be fixedly connected to the bag opening docking plate 521 of the intercepting filter assembly 52. ​​Therefore, only when the sediment filter bucket 530 of the sediment filter assembly 53 is installed on the top of the sewage receiving chamber 310 of the sewage tank 31 through the fixedly connected return sewage docking pipe joint 51, and the sediment filter bucket 530 of the sediment filter assembly 53 is also equipped with a replaceable intercepting filter assembly 52, can the interference release cantilever 56 be used to cancel the interference stop of the box cover interference assembly 35 on the sewage tank cover 32.

[0199] Exemplarily, in an embodiment of the present application, if the sedimentation filter bucket 530 of the sedimentation filter assembly 53 has the extended channel 531 described above, then, when the filter protection mechanism 50 is installed at the top of the sewage holding chamber 310 at the top opening of the sewage tank 31, the pry bar tail 352 can be suspended below the extended channel 531, and the interference release cantilever 56 can extend from the pocket docking plate 521 to the bottom of the extended channel 531 to press the pry bar tail 352.

[0200] Fig.18 This is a structural schematic diagram of a sewage tank of a water tank assembly in an embodiment of the present application being equipped with a sewage tank overflow prevention assembly. Fig.19 This is a schematic diagram of the suction principle of the sewage tank of the water tank assembly in the embodiment of the present application being equipped with a sewage tank anti-overflow assembly. Fig.18 and Fig.19In the embodiment of the present application, the sewage tank assembly 30 may further include a sewage tank anti-overflow assembly 37, and the sewage tank anti-overflow assembly 37 may be adjacent to the vent seat 317 in the sewage receiving chamber 310, and the sewage tank anti-overflow assembly 37 may be suspended above the sewage liquid level of the filtered recycled sewage contained in the sewage receiving chamber 310. When the sewage liquid level rises to a preset sewage liquid level threshold height, the sewage tank anti-overflow assembly 37 may be adsorbed on the vent seat 317 based on the suction of the suction mechanism, and the vent seat 317 is blocked by the adsorbed sewage tank anti-overflow assembly 37, so that the suction airflow is interrupted, thereby interrupting the continued injection of the recycled sewage in the base sewage pipe of the base station into the sewage tank 31.

[0201] For example, in an embodiment of the present application, the sewage tank overflow prevention assembly 37 may include a swing cantilever 371, a sewage tank float 372, and a floating cover plate 373. The swing cantilever 371 may be rotatably mounted on one side of the vent seat 317. The sewage tank float 372 is fixedly mounted on one end of the swing cantilever 371 away from the vent seat 317. The sewage tank float 372 is suspended on the sewage liquid surface, and the floating cover plate 373 is fixed on one end of the swing cantilever 371 close to the vent seat 317. In this case, the swing cantilever 371 may swing in response to the rise and fall of the sewage tank float 372, and the swing of the swing cantilever 371 may cause the floating cover plate 373 and the sewage tank float 372 to move in opposite directions. Thus, when the sewage level in the sewage holding chamber 310 of the sewage tank 31 rises to a preset sewage level threshold height, the buoyancy of the sewage tank float 372 can drive the floating cover 373 to move downward toward the exhaust hole seat 317 through the swinging cantilever 371, and the floating cover 373 can be adsorbed on the exhaust hole seat 317 based on the suction of the suction mechanism to block the exhaust hole seat 317 and interrupt the suction airflow and the recycled sewage injected with the suction airflow.

[0202] Fig. 20 This is a schematic diagram of the deployment of the sewage discharge pipe assembly of the sewage tank of the water tank assembly in the embodiment of the present application. Fig. 20 In an embodiment of the present application, the sewage tank assembly 30 may also include a sewage discharge pipe assembly 38. The sewage discharge pipe assembly 38 may be located at the bottom of the sewage tank 31 (i.e., below the sewage holding chamber 310), and the bottom of the sewage holding chamber 310 has a discharge opening connected to the sewage discharge pipe assembly 38.

[0203] Exemplarily, in an embodiment of the present application, the sewage tank assembly 30 may further include a sewage tank buried pipe base 319, which may be located at the bottom of the sewage tank 31 (i.e., below the sewage holding chamber 310), and the sewage discharge pipe assembly 38 may be located in the sewage tank buried pipe base 319.

[0204] Exemplarily, in an embodiment of the present application, a sewage tank pipe buried base 319 may be sealed on one side thereof with a sewage tank pipe plug 33, the sewage tank pipe plug 33 may be sealed and plugged with a sewage discharge joint 338 located outside the sewage tank 31, and the sewage discharge pipe assembly 38 may be connected to the sewage discharge joint 338 outside the sewage tank 31.

[0205] For example, in an embodiment of the present application, the sewage discharge pipe assembly 38 may include a sewage tank pipeline drive assembly 380, a sewage discharge funnel 381, and a sewage discharge one-way valve 382. The sewage discharge funnel 381 may be fixedly installed at the bottom of the sewage receiving chamber 310 below the discharge opening connected to the sewage discharge pipe assembly 38. The sewage discharge one-way valve 382 may be connected to the sewage discharge joint 338 outside the sewage tank 31. Moreover, the sewage tank pipeline drive assembly 380 may be connected between the sewage discharge funnel 381 and the sewage discharge one-way valve 382. For example, the sewage tank pipeline drive assembly 380 may include a water pump. Thus, based on the drive of the sewage tank pipeline drive assembly 380, the recycled sewage stored in the sewage receiving chamber 310 of the sewage tank 31 may be discharged to the outside of the sewage tank 31 through the sewage discharge pipe assembly 38. Moreover, the sewage discharge one-way valve 382 may prevent the discharged recycled sewage from flowing back. For example, the sewage discharge one-way valve 382 may include a duckbill one-way valve.

[0206] For example, in the embodiment of the present application, after the recycled sewage is filtered by the filter protection mechanism 50, a small amount or a very small amount of small solid particles of dirt will inevitably remain. After the sewage tank assembly 30 is used for a long time, the small solid particles of dirt may still cause the bottom of the sewage holding chamber 310 to communicate with the discharge opening of the sewage discharge pipe assembly 38, or the sewage discharge pipe assembly 38 to cause flow obstruction. At this time, it is necessary to dredge. In order to facilitate dredging, in the embodiment of the present application, the sewage tank assembly 30 may also include a manual dredging assembly 39, and the manual dredging assembly 39 is movable and suspended above the discharge opening of the sewage holding chamber 310 to communicate with the sewage discharge pipe assembly 38. Therefore, manual dredging can be achieved by repeatedly punching the discharge opening of the sewage holding chamber 310 to communicate with the sewage discharge pipe assembly 38 through the manual dredging assembly 39.

[0207] Exemplarily, in an embodiment of the present application, the manual unclogging assembly 39 may include a handle 391 and a unclogging end 392. The unclogging end 392 may be movably suspended above the discharge opening of the bottom of the sewage holding chamber 310 that is connected to the sewage discharge pipe assembly 38. The handle 391 is fixed above the unclogging end 392, and the handle 391 may extend upward from the unclogging end 392 to the top of the sewage holding chamber 310, so as to facilitate holding the manual unclogging assembly 39 (i.e., the handle 391) from the top opening of the sewage tank 31 when the sewage tank cover 32 is opened.
