Example 1

[0027] like Figures 1-2 As shown, a drain assembly includes a drain assembly housing 101, a water inlet 102 opened on the drain assembly housing 101, a first connecting device provided on the drain assembly housing 101 for connecting to a drain pipe, a drain outlet 103 opened on the drain assembly housing 101, a second connecting thread 104 opened on the drain outlet 103 for connecting a corrugated pipe, and also includes a water seal structure provided inside the drain assembly housing 101.

[0028] In order to reduce production costs, the drain outlet 103 is arranged perpendicular to the axis of the inlet 102 to reduce mold opening costs and reduce production costs.

[0029] In order to form a water seal liquid surface inside the drain housing 101 and prevent backflow of odor, the water seal structure includes: a lower baffle 105 disposed inside the drain housing 101 to prevent fluid from flowing directly to the drain outlet 103, and an upper baffle 106 disposed between the drain outlet 103 and the lower baffle 105, wherein there is a height difference between the top of the upper baffle 106 and the bottom of the lower baffle 105.

[0030] In order to enhance the use stability, the height difference between the top of the upper baffle 106 and the bottom of the lower baffle 105 is at least 1.5 cm, which is used to ensure the height of the water seal liquid surface after the fluid is discharged.

[0031] In order to improve the drainage flow, the lower baffle 105 is a reverse L-shaped baffle and extends to the inside of the drain housing 101 to expand the drainage space.

[0032] In order to facilitate the cleaning of the sundries accumulated in the drain housing 101, the bottom of the drain housing 101 is further provided with a cleaning device cooperating with the water seal structure to improve the drainage flow and facilitate the cleaning of the sundries, which comprises: a cleaning port 108 opened in the drain housing 101 and corresponding to the counterflow channel 107 between the upper baffle 106 and the lower baffle 105, a cleaning cover 109 locked on the cleaning port 108.

[0033] In order to make the sundries settle together, thereby better cleaning the sundries, the cleaning port 108 extends to the bottom of the drain housing 101 to expand the fluid space and make the sundries better settle.

[0034] In order to make the fluid flowing into the drain housing 101 in the basin faster and smoother to the drainage port 103, the lower baffle 105 is further provided with a rounded corner 110 to prevent the sundries carried by the fluid from accumulating on the lower baffle 105 and to make the fluid flow better.

[0035] In order to facilitate the installation of the drain and adjust the orientation of the drainage port 103 of the drain housing 101, the first connecting device comprises: a first limiting ring 111 provided on the drain housing 101 at the water inlet 102, a first rotating sleeve 112 sleeved on the drain housing 101, a second limiting ring 113 provided on the first rotating sleeve 112 for clamping the first limiting ring 111, and a first connecting thread 114 opened on the rotating sleeve.
