[0004] In summary, the structure of the existing water drainer needs to be further improved. INVENTION CONTENT

[0005] The application aims at solving the problem of peculiar smell penetration in the existing water drainer, and provides a water drainer with double deodorization structure.

[0006] In order to achieve the above application purpose, the utility model takes the following technical scheme:

[0007] The water drainer with double deodorization structure comprises a main body and a deodorization cup, the main body is provided with an inner cavity with open upper end, the side wall of the inner cavity is provided with a drain port, the bottom of the main body is provided with a residue discharge port, the deodorization cup detachably closes the residue discharge port, the lower part of the drain port is provided with a first baffle, so that the lower part of the main body forms a water seal area, the inner cavity is provided with a baffle cover outside the drain port, the baffle cover is open at the lower end, and the height of the bottom is lower than that of the water seal area.

[0008] This invention creates a water seal zone at the bottom of the main body by installing a baffle at the drain outlet. The water seal zone forms a physical barrier, and the baffle design prevents odor gases from entering the drain assembly and being discharged into the room by trapping them on the side of the baffle closest to the drain outlet.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings:

[0033] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "inner", and "outer" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing this utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0034] See Figures 1-12 As shown, this utility model discloses a drain with a double odor-proof structure, including a main body 1 and an odor-proof cup 6. The main body 1 has an inner cavity with an open upper end, a drain outlet 12 on the side wall of the inner cavity, and a residue discharge outlet 10a at the bottom. The odor-proof cup 6 can be detachably sealed to close the residue discharge outlet 10a. A first baffle 15 is provided at the lower part of the drain outlet 12, so that the lower part of the main body 1 forms a water seal area. A baffle 13 is provided on the outside of the drain outlet 12 in the inner cavity. The lower end of the baffle 13 is open, and its bottom height is lower than the height of the water seal area.

[0035] To further enhance the comfort and hygiene of the living environment, the drain assembly also includes a water-sealing component to seal the inner cavity of the main body 1. This water-sealing component acts as a second line of defense, effectively preventing the escape of odorous gases even if the water seal area or baffle 13 temporarily fails for some reason. This dual-protection design not only reduces the possibility of odor generation at its source but also effectively isolates sewer odors through two barriers, greatly improving the user's living quality. Furthermore, the water-sealing component includes a water-sealing cover 4, which is installed at the upper opening of the main body 1. In this solution, the water-sealing component has a simple and effective structure, is easy to install and disassemble, and facilitates maintenance and cleaning for users.

[0036] To improve the overall stability and durability of the drainer, and to facilitate daily maintenance and upkeep by users, the main body 1 includes an outer shell 10 and an inner cup 19. The inner cup 19 is located in the upper part of the inner cavity of the outer shell 10, and the two are connected by an upper ring seal. The drain outlet 12, the residue discharge outlet 10a and the baffle 13 are all located on the outer shell 10 and below the baffle 13. A water outlet is provided at the bottom of the inner cup 19.

[0037] To ensure a tight connection between the outer shell 10 and the inner cup 19, a fixing ring 16 is provided on the outer shell 10. The fixing ring 16 is threadedly connected to the main body 1. The fixing ring 16 has an upper support edge, and a washer 17 and a sealing ring 18 are sequentially placed on the upper support edge.
