[0026] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] Reference Figures 1 to 6The embodiment of the utility model provides a double basin drainage system, comprising a first water inlet pipe 1, a second water inlet pipe 2, a connecting pipe group connected between the first water inlet pipe 1 and the second water inlet pipe 2, and a centralized water outlet pipe group connected to the connecting pipe group. The first water inlet pipe 1 and the second water inlet pipe 2 are respectively connected to the water outlets of the two basins, and the connecting pipe group transports the water discharged into the two water inlet pipes to the centralized water outlet pipe group, and the water is discharged from the centralized water outlet pipe group.

[0028] The first water inlet pipe 1 and the second water inlet pipe 2 are set to be L-shaped. The first water inlet pipe 1 and the second water inlet pipe 2 respectively include a vertical water inlet section and a horizontally rearward water flow section. The vertical water inlet section is connected to the water outlet of the basin. The horizontally rearward water flow section is vertically located behind the water inlet section. The connecting pipe group is horizontally connected between the two water flow sections. The connecting pipe group includes a first connecting section and a second connecting section respectively connected to the water flow section of the first water inlet pipe 1 and the water flow section of the second water inlet pipe 2, and a third connecting section connected to the centralized water outlet pipe group. The third connecting section is located on the same side as the first connecting section, so that the water flow section, the connecting pipe group and the centralized water outlet pipe group are all located behind the vertical water inlet section and are rear-placed. The water flow section and the connecting pipe group are located above the space below the pool and will not occupy the central space of the cabinet, thereby freeing up storage space for the cabinet.

[0029] The centralized outlet pipe group is located on the same side as the first water inlet pipe 1. If the first water inlet pipe is located on the left, the centralized outlet pipe group is located on the left. In order to meet the requirements of the centralized outlet pipe group being placed at the back and being able to be installed according to the needs, the centralized outlet pipe group is large in size and is placed downwards. If there is no installation space on one side (left or right) or other reasons lead to the limitation of the installation position of the centralized outlet pipe group, it is necessary to set up a double basin drainage system with a left-mounted structure and a double basin drainage system with a right-mounted structure. Figure 1 As shown, the first water inlet pipe 1 and the centralized water outlet pipe group are located on the left side, which is a double basin drainage system with a left-mounted structure. If the centralized water outlet pipe group is required to be installed on the right side, a double basin drainage system with a right-mounted structure is required, such as Figure 2 shown.

[0030] The socket connection is used to connect two sections of pipes to each other, that is, one pipe opening (which can be called the spigot) is inserted into the other pipe opening (which can be called the socket), and a sealing material is used to achieve a sealed connection of the pipes.

[0031] A socket connection is set between the water-passing section of the first water inlet pipe 1 and the first connecting section, and the connection part between the water-passing section of the first water inlet pipe 1 and the first connecting section is locked by the first threaded locking sleeve 11; a socket connection is set between the water-passing section of the second water inlet pipe 2 and the second connecting section, and the connection part between the water-passing section of the second water inlet pipe 2 and the second connecting section is locked by the second threaded locking sleeve 21; a socket connection is set between the centralized water outlet pipe group and the third connecting section, and the connection part between the centralized water outlet pipe group and the third connecting section is locked by the third threaded locking sleeve 31. Thus, the orientation between the water-passing section of the first water inlet pipe 1 and the first connecting section can be adjusted by relative rotation, the orientation between the water-passing section of the second water inlet pipe 2 and the second connecting section can be adjusted by relative rotation, and the orientation between the centralized water outlet pipe group and the third connecting section can be adjusted by relative rotation. When adjusting, first loosen the corresponding threaded locking sleeve, then rotate and adjust the water pipe that needs to be rotated, and finally lock the corresponding threaded locking sleeve.

[0032] Rotate the first water inlet pipe 1 180°, the second water inlet pipe 2 180°, and the centralized water outlet pipe group 180°, so that the vertical water inlet section of the first water inlet pipe 1 and the vertical water inlet section of the second water inlet pipe 2 face downward, rotate the centralized water outlet pipe group as a whole to face upward, and then turn the double-basin drainage system 180° as a whole, so as to complete the interchange between the left-mounted double-basin drainage system and the right-mounted double-basin drainage system, and realize that the same double-basin drainage system can be installed on the left or on the right, which can meet different installation requirements.

[0033] The connecting pipe group includes a T-shaped three-way pipe 3 and an L-shaped two-way pipe 4. The T-shaped three-way pipe 3 includes a first connecting section and a third connecting section located in the same straight line, and a fourth connecting section vertically connected to the first connecting section and the third connecting section. The L-shaped two-way pipe 4 includes a second connecting section and a fifth connecting section vertically connected to the second connecting section. The fourth connecting section and the fifth connecting section are connected by a socket connection, and the connecting part of the two is locked by a fourth threaded locking sleeve 41. Therefore, the orientation between the T-shaped three-way pipe 3 and the L-shaped two-way pipe 4 can be adjusted by relative rotation, which can meet the needs of various position adjustments.

[0034] The centralized water outlet pipe group includes an inverted L-shaped water elbow 5, a water seal and deodorization structure 6 and a water outlet pipe 7, and the third connecting section is connected to the transverse section of the water elbow 5. The water seal and deodorization structure 6 is connected below the vertical section of the water elbow 7, and the water outlet pipe 7 is connected to the side of the water seal and deodorization structure 6.

[0035] The water seal and odor-proof structure 6 includes a water seal and odor-proof pipe and a slag collecting cup 64. The water seal and odor-proof pipe includes an upper joint 61 connected to the water elbow 5, an inner tube 62 and an outer tube 63 connected to the lower end of the upper joint 61. The outer tube 63 is arranged outside the inner tube 62, and the lower end of the inner tube 62 is connected to the inner cavity of the outer tube 63; the inner cavity of the upper joint 61 is connected to the inner cavity of the inner tube 62, and the inner tube 62 separates the inner cavity of the upper joint 61 from the inner cavity of the outer tube 63, and the slag collecting cup 64 is connected to the lower end of the outer tube 63. The outer tube 63 is laterally provided with a water outlet joint 65, and the water outlet pipe 7 is connected to the water outlet joint 65. The vertical section of the water elbow 5 is connected to the upper joint 61 by a socket connection, and the connection between the two is locked by a fifth threaded locking sleeve.

[0036] The inner cavity of the upper joint 61 is connected with the inner cavity of the inner tube 62 to form an inner cavity, and the inner cavity of the slag collecting cup 64 is connected with the inner cavity of the outer tube 63 to form an outer cavity. The outer cavity is arranged outside the inner cavity, and the inner cavity and the outer cavity are connected at the lower end. The water outlet pipe 7 is connected with the outer cavity through the water outlet joint 65. The position of the water outlet joint 65 is higher than the lower end of the inner tube 62, so that the connection position of the water outlet pipe 7 and the outer cavity is higher than the connection position of the inner cavity and the outer cavity. The connection position of the water outlet pipe 7 and the outer cavity is higher than the connection position of the inner cavity and the outer cavity, so that the water flowing into the outer cavity will not be completely discharged from the water outlet pipe, and water will be stored in the position of the outer cavity lower than the connection position of the water outlet pipe and the outer cavity, so that the stored water will block the connection position of the inner cavity and the outer cavity, realizing water sealing and deodorization.

[0037] Two overflow joints 9 are provided on the water elbow 5, and the overflow joints 9 are used to communicate with the overflow port of the pool through a pipeline, and connect the water flowing into the overflow port to the water elbow 5. The two overflow joints 9 are arranged symmetrically and tilted to each other, forming a Y-shaped structure with the vertical section of the water elbow 5. Such a structure has a fast diversion speed and solves the problem of the overflow expansion parts supporting the basin when installing the water.

[0038] The water flow section of the first water inlet pipe 1 and the water flow section of the second water inlet pipe 2 are respectively provided with an anti-odor one-way valve, which includes a valve 8 rotatably installed in the water flow section, the rotation axis of the valve 8 is located above the gravity direction, and the valve 8 is tilted downward from the water inlet direction to the water outlet direction. When there is no water to be discharged, the valve 8 tilts downward from the water inlet direction to the water outlet direction under the action of natural gravity, and the valve 8 is in a closed state (such as Figure 5 As shown), to achieve odor prevention; when sewage backflows, the sewage pushes the valve 8 in the reverse direction, making the valve 8 close more tightly, to achieve backflow prevention; when water is discharged, the impact force of the water will open the inclined valve 8 in the forward direction, and the valve 8 is in an open state (as shown in FIG. Figure 6 to achieve normal drainage.

[0039] The first level of odor prevention is achieved through the anti-odor one-way valve, and the second level of odor prevention is achieved through the water seal anti-odor structure, thus achieving the purpose of double odor prevention while preventing insects and backflow.
