[0046] The present application provides a waste liquid treatment system which can more smoothly treat waste liquid.

[0047] Fig. 1 shows a structural schematic diagram of a waste liquid treatment system provided by an embodiment of the present application, Fig. 2 shows a structural schematic diagram of a waste liquid treatment device in Fig. 1, and Fig. 3 shows a structural schematic diagram of a waste liquid collection device in Fig. 1. The waste liquid treatment system provided by the present application comprises a waste liquid treatment device 10 and a waste liquid collection device 20. The waste liquid treatment device 10 is used in combination with the waste liquid collection device 20 to discharge dirt in the waste liquid collection device 20 and disinfect the waste liquid collection device 20.

[0048] In the present embodiment, there can be multiple waste liquid collection devices 20 paired with the waste liquid treatment device 10, that is, one waste liquid treatment device 10 can be combined with multiple waste liquid collection devices 20.

[0049] As shown in Fig. 1 and Fig. 3, a containing tank 21, a negative pressure generating device (not shown in the figure) and a suction head (not shown in the figure) can be arranged in the waste liquid collection device 20. The negative pressure generating device is connected with the containing tank 21 and is used to generate negative pressure in the containing tank 21. The containing tank 21 is connected with the outside through the suction head and sucks dirt through the suction head.

[0050] The waste liquid treatment device 10 comprises a main machine 11 and a first docking module 12, and a second docking module 22 is arranged in the waste liquid collection device 20. When the waste liquid collection device 20 finishes collecting dirt or the liquid level of the containing tank 21 reaches the limit, the waste liquid collection device 20 will be transported to the waste liquid treatment device 10. The waste liquid collection device 20 is close to the waste liquid treatment device 10 to make the first docking module 12 and the second docking module 22 complete docking.

[0051] A control unit 111 (see Fig. 16), a suction device 112, a cleaning liquid injection device 113 and a steam generating device 114 are arranged in the main machine 11. When the first module 12 and the second module 22 complete docking, the control unit 111 first sucks dirt in the containing tank 21 of the waste liquid collection device 20 through the suction device 112, then washes the containing tank 21 through the cleaning liquid injection device 113, and finally disinfects the containing tank 21 through the steam generating device 114.

[0052] The first docking module 12 comprises a first end which is aligned with the second docking module 22 first, and a second end which is opposite to the first end. That is, the first end is the end of the first docking module 12 which is away from the host 11, and the second end is the end of the first docking module 12 which is close to the host 11.

[0053] Fig. 4 shows a structural schematic diagram of the first docking module of the waste liquid treatment device and the second docking module of the waste liquid collection device, Fig. 5 shows a structural schematic diagram of the first docking module and the second docking module when they are docked, Fig. 6 shows a structural schematic diagram of the cover plate of the first docking module in Fig. 5, Fig. 7 shows an exploded structural schematic diagram of the first docking module from a first perspective, Fig. 8 shows an exploded structural schematic diagram of the first docking module from a second perspective, and Fig. 9 shows a structural schematic diagram of the first docking module and the second docking module after the cover plate and the baffle of the first docking module are removed. Please continue to refer to Figs. 3 to 9. More specifically, the first docking module 12 comprises a base 121, a first support plate 122, a power source 123, a guide rod 124, and a plurality of moving joints 125. The second docking module 22 comprises a second support plate 221 and a plurality of fixed joints 222.

[0054] The guide rod 124 is fixed on the base 121, the first support plate 122 is sleeved on the guide rod 124, the first support plate 122 is movably arranged on the guide rod 124 along the axis direction of the guide rod 124, and the plurality of moving joints 125 are arranged on the first support plate 122. The power source 123 is connected with the first support plate 122 and drives the first support plate 122 to move on the guide rod 124. The plurality of fixed joints 222 are arranged on the second support plate 221.

[0055] After the second docking module 22 is moved above the first docking module 12 and the positions of the fixed joints 222 and the moving joints 125 are corresponded, the power source 123 drives the plurality of moving joints 125 on the first support plate 122 to move upward under the control of the control unit 111, so that the moving joints 125 are docked with the fixed joints 222. After the moving joints 125 and the fixed joints 222 are docked, the suction device 112, the cleaning liquid injection device 113, and the steam generating device 114 are connected with the containing tank 21 through the corresponding moving joints 125 and fixed joints 222.

[0056] In the embodiment, the plurality of mobile joints 125 include first type joints 1251 and second type joints 1252. When the second docking module 22 moves above the first docking module 12 and starts to dock, the first type joints 1251 and the second type joints 1252 are different in distance from the respective corresponding fixed joints 222 on the second docking module 22. In other words, during the movement of the mobile joints 125 by the power source 123 towards the fixed joints 222, the first type joints 1251 and the second type joints 1252 dock with the respective corresponding fixed joints 222 in a sequence, the distance between the first type joints 1251 and the corresponding fixed joints 222 is less than the distance between the second type joints 1252 and the corresponding fixed joints 222, that is, the first type joints 1251 dock with the corresponding fixed joints 222 earlier than the second type joints 1252. Through the sequence arrangement, it is helpful for the respective joints to overcome the errors in the manufacturing and movement process to better dock between the respective joints.

[0057] In the embodiment, the second type joints 1252 are movably arranged on the first support plate 122. It needs to be explained that the above-mentioned movably means that the second type joints 1252 can move along the direction of the axis thereof and / or swing around the axis thereof relative to the first support plate 122. The second docking module 22 further includes a first elastic member 1253, one end of the first elastic member 1253 is connected with the first support plate 122, and the other end is connected with the second type joints 1252. Preferably, the first elastic member 1253 is a spring and is sleeved on the second type joints 1252.

[0058] More specifically, the first type joints 1251 are closer to the first end of the first docking module 12 than the second type joints 1252, and the second type joints 1252 are closer to the second end of the first docking module 12 than the first type joints 1251.

[0059] In the embodiment, the mobile joints 125 can be divided into three types according to the use, which are respectively a drainage joint, a flushing joint and two steam joints. The drainage joint and the flushing joint are arranged side by side in the direction perpendicular to the relative movement of the waste liquid collecting device 20 and the waste liquid treatment device 10 when docking (that is, the direction from the first end to the second end of the first docking module 12), and the two steam joints are arranged side by side in the direction perpendicular to the relative movement of the waste liquid collecting device 20 and the waste liquid treatment device 10 when docking. Among the mobile joints 125, compared with the steam joints, the drainage joint and the flushing joint are closer to the waste liquid collecting device 20 in the first docking module 12.

[0060] The liquid drainage connector is connected to the suction device 112 in the main machine 11, the flushing connector is connected to the cleaning liquid injection device 113 in the main machine 11, and the steam connector is connected to the steam generation device 114 in the main machine 11.

[0061] In the embodiment, the first type of connector 1251 can be the liquid drainage connector and the flushing connector, and the second type of connector 1252 can be the steam connector.

[0062] In the embodiment, the power source 123 can be an electric motor to drive the first support plate 122 to move up and down on the guide rod 124 under the control of the control unit 111.

[0063] To ensure smooth movement, the guide rod 124 can be multiple, and in the embodiment, the guide rod 124 can be at least two, and the two guide rods 124 are arranged in a direction from the first end to the second end of the first docking module 12. That is, one of the guide rods 124 is located on one side of the first end of the first docking module 12, and the other guide rod 124 is located on one side of the second end of the first docking module.

[0064] The base 121 includes a top plate 1211 and a bottom plate 1212, and the guide rod 124 is fixed between the top plate 1211 and the bottom plate 1212. A second elastic member 1241 is also sleeved on the guide rod 124 close to the main machine 11, i.e. on the guide rod 124 on the side of the second end of the first docking module 12, and the second elastic member 1241 is supported between the first support plate 122 and the top plate 1211. It can be understood that the second elastic member 1241 can exert a downward pressure on the first support plate 122 during the lifting of the first support plate 122 by its compression, so as to prevent the first support plate 122 from being raised on the second end of the first docking module 12.

[0065] Further, a cover plate 1261 is arranged on the top of the first docking module 12, and a baffle is arranged around the periphery of the first docking module 12.

[0066] The cover plate 1261 is arranged above the top plate 1211 and can move relative to the top plate 1211 in the direction from the first end to the second end of the first docking module 12. During the docking process, the second support plate 221 of the second docking module 22 can push the cover plate 1261 to move in the direction of the second end of the first docking module 12 as the second docking module 22 moves towards the first docking module 12; and after the second docking module 22 is separated from the first docking module 12, the cover plate 1261 can be arranged on the first docking module 12 again to protect the first docking module 12.

[0067] Specifically, a third elastic member 1263 is arranged between the top plate 1211 and the cover plate 1261, and is connected between the top plate 1211 and the cover plate 1261. Specifically, one end of the third elastic member 1263 is connected to the top plate 1211 at the end where the second end of the first docking module 12 is located, and the other end is connected to the cover plate 1261 at the end where the second end of the first docking module 12 is located. The third elastic member 1263 is used to provide an elastic force for automatically resetting the cover plate 1261 after the second docking module 22 is separated from the first docking module 12. More specifically, when the second docking module 22 is pushed into the first docking module 12, the third elastic member 1263 is gradually stretched, and after the second docking module 22 is separated from the first docking module 12, it retracts to release the elastic force.

[0068] Specifically, the cover plate 1261 is also provided with a first position sensing element 1264 and a second position sensing element 1265. The first position sensing element 1264 is arranged at the end of the cover plate 1261 away from the second docking module 22, i.e. at the second end of the first docking module 12; the second position sensing element 1265 is arranged at the end of the cover plate 1261 close to the second docking module 22, i.e. at the first end of the first docking module 12. A first position probe 1266 is arranged on the top plate 1211, and the first position probe 1266 is electrically connected to the control unit 111. When the first position probe 1266 corresponds to the first position sensing element 1264, it indicates that the first docking module 12 is separated from the second docking module 22 or that the two are ready to be docked; when the first position probe 1266 corresponds to the second position sensing element 1265, it indicates that the first docking module 12 and the second docking module 22 have completed alignment and can be docked with the mobile joint 125 and the fixed joint 222.

[0069] In this embodiment, the first position sensing element 1264 and the second position sensing element 1265 can be magnetic elements, and the first position probe 1266 can be a magnetic switch.

[0070] Fig. 10 shows a top view of the second docking module, Fig. 11 shows a sectional view of the XI-XI direction in Fig. 10, and Fig. 12 shows an exploded view of the relevant structure in Fig. 11. As shown in Figs. 10-12, the positions and types of the fixed joints 222 correspond to the positions and types of the mobile joints 125. It can be understood that the fixed joints 222 include third type joints 2221 corresponding to the first type joints 1251 and fourth type joints 2222 corresponding to the second type joints 1252. In this embodiment, the third type joints 2221 can be liquid mixing joints and flushing joints, and the fourth type joints 2222 can be steam joints. Similarly, the fourth type joints 2222 are closer to the first docking module 12 than the third type joints 2221 on the second support plate 221.

[0071] The distance between the first type of joint 1251 and the third type of joint 2221 is less than the distance between the second type of joint 1252 and the fourth type of joint 2222. Preferably, when the second docking module 22 is moved above the first docking module 12, the distance between the lower end of the third type of joint 2221 and the upper surface of the first support plate 122 is less than the distance between the lower end of the fourth type of joint 2222 and the upper surface of the first support plate 122.

[0072] In order to more effectively achieve smooth docking between the mobile joint 125 and the fixed joint 222, one of the first type of joint 1251 and the second type of joint 1252 can be a male joint, and the other of the first type of joint 1251 and the second type of joint 1252 can be a female joint. It can be understood that the types of the third type of joint 2221 and the fourth type of joint 2222 can be determined according to the first type of joint 1251 and the second type of joint 1252.

[0073] In the present embodiment, the first type of joint 1251 can be a female joint, and the second type of joint 1252 can be a male joint. Correspondingly, the third type of joint 2221 can be a male joint, and the fourth type of joint 2222 can be a female joint.

[0074] In order to achieve smooth docking between the mobile joint 125 and the fixed joint 222, in the present embodiment, the fixed joint 222 can be floating. Specifically, the second docking module 22 further comprises a connecting cylinder 223, a guide cylinder 224, and a fourth elastic member 225. A connecting hole (not labeled in the figure) is formed in the second support plate 221, the connecting cylinder 223 is fixed in the connecting hole and extends downward. The guide cylinder 224 is floatingly arranged in the connecting cylinder 223, and the area of the cross section of the guide cylinder 224 in the direction from top to bottom gradually increases in the direction perpendicular to the axis of the guide cylinder 224. Preferably, the guide cylinder 224 is in the shape of a downwardly opening bell mouth. The fourth elastic member 225 is arranged in the connecting cylinder 223 and located between the connecting cylinder 223 and the guide cylinder 224. Preferably, the fourth elastic member 225 can be sleeved outside the guide cylinder 224. The fourth elastic member 225 is arranged such that the guide cylinder 224 is compressed when subjected to an upward force relative to the connecting cylinder 223, and automatically returns to the original position after the force is removed. The third type of joint 2221 and the fourth type of joint 2222 are respectively fixed in the respective guide cylinders 224. That is, there can be multiple sets of the connecting cylinder 223, the guide cylinder 224, and the fourth elastic member 225, and each set is fixed with one third type of joint 2221 or one fourth type of joint 2222.

[0075] When the first type joint 1251 or the second type joint 1252 moves upward, the guide cylinder 224 will automatically guide the first type joint 1251 and the second type joint 1252, and meanwhile, depending on its swing or up-down movement, accommodate the position error between the first docking module 12 and the second docking module 22, so that the connection between the first type joint 1251 and the third type joint 2221, and the connection between the second type joint 1252 and the fourth type joint 2222 are more accurate.

[0076] More specifically, a tapered connecting surface 2241 is formed at the upper end of the guide cylinder 224, and the area of the cross section of the tapered connecting surface 2241 perpendicular to the axis of the guide cylinder 224 gradually increases from the direction close to the second support plate 221 to the direction away from the second support plate 221. When the guide cylinder 224 is arranged in the connecting cylinder 223, the tapered connecting surface 2241 is arranged on the upper end surface of the connecting cylinder 223. Through the arrangement of the tapered connecting surface 2241, the guide cylinder 224 can swing around its own axis relative to the connecting cylinder 223.

[0077] A stop edge 2242 is further arranged at the lower end of the guide cylinder 224, and the distance between the edge of the stop edge 2242 and the axis of the guide cylinder 224 is greater than the diameter of the connecting cylinder 223. That is, during the upward movement of the guide cylinder 224 relative to the connecting cylinder 223, the stop edge 2242 will abut against the lower end surface of the connecting cylinder 223 to limit the upward movement distance of the guide cylinder 224 relative to the connecting cylinder 223.

[0078] Preferably, the distance between the bottom of the guide cylinder 224 corresponding to the third type joint 2221 and the first type joint 1251 is smaller than the distance between the bottom of the guide cylinder 224 corresponding to the fourth type joint 2222 and the second type joint 1252.

[0079] Fig. 13 shows the shaft side structure of the first docking module, Fig. 14 shows the side view of the structure of Fig. 13, and Fig. 15 shows the cross-sectional view of XV-XV direction of Fig. 14. As shown in Figs. 13-15, in order to ensure the floating of the second type joint 1252, the first docking module 12 can further include a connecting column 1254 which is arranged on the first support plate 122 in a floating manner. The second type joint 1252 is arranged in the connecting column 1254.

[0080] The first clamping plate 1255 and the second clamping plate 1256 are arranged on the connecting column 1254, and the first supporting plate 122 is arranged between the first clamping plate 1255 and the second clamping plate 1256. The elastic gaskets 1257, such as Teflon gaskets, are arranged between the first clamping plate 1255 and the first supporting plate 122 and between the second clamping plate 1256 and the first supporting plate 122. The up-and-down movement and swing of the connecting column 1254 relative to the first supporting plate 122 can be limited by the thickness of the elastic gaskets 1257 and the elasticity of the connecting column 1254.

[0081] In the embodiment, the second clamping plate 1256 can be a clamping spring fixed additionally during assembly, so as to reduce the assembly difficulty of the connecting column 1254.

[0082] The mounting edge 1258 is formed at the top end of the connecting column 1254, and the first elastic member 1253 is sleeved outside the connecting column 1254, one end of the first elastic member 1253 abutting against the mounting edge 1258, and the other end abutting against the first supporting plate 122.

[0083] Please continue to refer to FIG. 9. In the embodiment, the third position sensing element 1267 and the fourth position sensing element 1268 are arranged on the base 121 at intervals along the height direction, and the second position probe 1269 is fixedly connected to the first supporting plate 122. When the third position sensing element 1267 is opposite to the second position probe 1269, it represents that the first supporting plate 122 is at the initial position; when the fourth position sensing element 1268 is opposite to the second position probe 1269, it represents that the first supporting plate 122 is at the position where each joint is completely docked.

[0084] The third position sensing element 1267 and the fourth position sensing element 1268 can be electrically connected to the control unit 111 to sense the position of the first supporting plate 122.

[0085] In the embodiment, the third position sensing element 1267 and the fourth position sensing element 1268 can be photoelectric sensors. The second position probe 1269 can be a baffle.

[0086] FIG. 16 shows the system block diagram of the waste liquid treatment system. In the embodiment, the control unit 111 can be electrically connected to the suction device 112, the cleaning liquid injection device 113, and the steam generating device 114 in the host computer 11, and control each device.

[0087] Further, according to the characteristics of the position sensing device, one of the first position sensing element 1264 and the second position sensing element 1265 and the first position probe 1266 can be electrically connected to the control unit 111 to sense whether the second docking module 22 moves to the upper side of the first docking module 12.

[0088] The third position sensing element 1267 and the fourth position sensing element 1268, as well as the second position probe 1269, are electrically connected to the control unit 111 to sense whether the power source 133 moves the first support plate 122 to the position.

[0089] Fig. 17 is a side view of the connection between the joints in the first docking module and the joints in the second docking module in an undocked state, Fig. 18 is a cross-sectional view of the direction XVIII-XVIII in Fig. 17, Fig. 19 is a side view of the connection between the joints in the first docking module and the joints in the second docking module in a docked state, and Fig. 20 is a cross-sectional view of the direction XX-XX in Fig. 19.

[0090] The docking process will be described below in combination with Figs. 4, 5, 17-20.

[0091] When the waste liquid collected in the waste liquid collecting device 20 needs to be treated, the waste liquid collecting device 20 is first moved to the waste liquid treatment device 10. Then the second docking module 22 is moved towards the first docking module 12. During the docking process, the second docking module 22 pushes the cover plate 1261 to move backward.

[0092] During the movement, when the first position sensing element 1264 is out of contact with the first position probe 1266, it indicates the start of the docking process. When the second position sensing element 1265 is in contact with the first position probe 1266, the first docking module 12 and the second docking module 22 have completed the alignment process.

[0093] After the first docking module 12 and the second docking module 22 complete the alignment, the power source 123 is started to drive the movement joints 125 on the first support plate 122 to move upward.

[0094] Since the first type of joint 1251 is docked with the corresponding fixed joint 222 before the second type of joint 1252 during the upward movement of the first support plate 122, the corresponding guide cylinder 224 on the third type of joint 2221 will guide the first type of joint 1251 first, and the first type of joint 1251 will be connected with the corresponding fixed joint 222 before the second type of joint 1252.

[0095] In the process of connection, when the third type joint 2221 is connected with the first type joint 1251, the third type joint 2221 will give the first type joint 1251 a downward reaction force, which acts on the first support plate 122, causing the end of the first support plate 122 where the second type joint 1252 is located to be raised upward, which easily causes the difficulty of alignment of the second type joint 1252 and the fourth type joint 2222, and the jamming of the first support plate 122 on the guide rod 124.

[0096] When the second type joint 1252 contacts the fourth type joint 2222, due to the floating arrangement of the second type joint 1252 and the presence of the first elastic member 1253, the first elastic member 1253 will store elastic energy through its compression, thereby relieving the raised condition of the first support plate 122 and facilitating the connection of the second type joint 1252 and the fourth type joint 2222.

[0097] When the fourth position sensing element 1268 is opposite to the second position probe 1269, it represents that each joint on the first docking module 12 and the second docking module 22 is aligned.

[0098] After the alignment of each joint is completed, the suction device 112, the suction device 112, the cleaning liquid injection device 113 and the steam generating device 114 in the host 11 are connected with the containing tank 21 through the respective joints.

[0099] The waste liquid in the containing tank 21 of the waste liquid collection device 20 is discharged through the liquid discharge joint, the containing tank 21 is flushed through the flushing joint, and then the containing tank 21 is sterilized through the steam joint.

[0100] After the sterilization is completed, the power source 123 drives the first support plate 122 to move downward, and the moving joint 125 is separated from the fixed joint 222. When the third position sensing element 1267 is opposite to the second position probe 1269, the first support plate 122 is lowered into position, and the moving joint 125 is completely separated from the fixed joint 222.

[0101] The first docking module 12 is separated from the second docking module 22, and the cover plate 1261 is gradually reset. When the first position sensing element 1264 on the cover plate 1261 is opposite to the first position probe 1266, it represents that the first docking module 12 and the second docking module 22 are completely separated, and the processing work of the waste liquid collection device 20 is completed.

[0102] In summary, in the embodiment, the first type of joint 1251 and the second type of joint 1252 have different distances from the respective third type of joint 2221 and the fourth type of joint 2224, so that the first type of joint 1251 and the second type of joint 1252 have a time difference when docking, which can facilitate the docking between multiple joints. By setting the first elastic member 1253 on the joint that docks later, i.e. the second type of joint 1252, the alignment of the joint that docks later can be facilitated, and the first support plate 122 can be prevented from being warped during docking.

[0103] Further, by setting the second elastic member 1241 on the guide rod 124, the first support plate 122 can be better prevented from being warped at one end where the second elastic member 1241 is located, so that the docking of the joints can be better performed.

[0104] The above merely illustrates the specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any changes or replacements within the technical scope disclosed by the present application can be easily thought of by those skilled in the art, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
