Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0027] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0028] Reference Figures 1 to 7As shown, an ultra-thin drain assembly includes a drain body 1, a cover body 2 and a water overflow body 3. The lower end of the drain body 1 passes through a wash basin. The cover body 2 is used to close the opening of the drain body 1. The water overflow body 3 includes a water overflow shell 31. The water overflow shell 3 includes a first pipe portion 311 and a second pipe portion 312. The side wall of the first pipe portion 311 is laterally connected to the second pipe portion 312. The portion of the drain body 1 passing through the wash basin is fixedly connected to the inside of the first pipe portion 311, and the two are connected to each other.

[0029] The portion of the drain body 1 that passes through the wash basin is fixedly connected to the first pipe portion 311 and hidden therein, thereby achieving the purpose of reducing the total height of the drain assembly of the utility model, thereby achieving the purpose of ultra-thin total thickness of the drain assembly. The second pipe portion 312 extends laterally and is connected to the drainage pipe 4, and is connected to the wall drainage outlet or floor drainage outlet of the toilet through the drainage pipe 4. The second pipe portion 312 is connected to the wall drainage outlet of the toilet through the drainage pipe 4. The above structure realizes an ultra-thin design of the drain assembly, shortens the overall height of the drain assembly extending below the wash basin, and increases the storage space of the storage cabinet below the wash basin.

[0030] Preferably, the first tube portion 311 and the second tube portion 312 are arranged in an L shape. Figure 5 As shown in the angle A, the second pipe portion 312 faces downward and has an angle of 92°-98° with the vertical plane, so that the sewage is discharged outward along the inclination angle of the second pipe portion 312, thereby preventing the sewage from flowing back into the first pipe portion 311. The lowest surface of the second pipe portion 312 is higher than the lowest surface of the bottom cover 32, thereby further reducing the overall thickness of the drainage assembly.

[0031] The water overflow shell 31 is installed under the wash basin, so the water overflow shell 31 determines the height of the drain assembly protruding from the wash basin. By setting the height of the water overflow body 3 to be less than or equal to 55 mm, the set size ensures that the first pipe portion 311 and the drain body 1 have a connection size of sufficient length to ensure the connection strength, and the ultra-thin design of the drain assembly can be achieved.

[0032] The side wall of the drain body 1 is provided with a plurality of water channels 12 arranged flush with the second pipe portion 312, and the number of the water channels 12 is preferably 3, thereby ensuring both the strength of the drain body 1 and the water discharge efficiency. The sewage from the wash basin flows through the first pipe portion 311 and then flows through the water channels 12 to the second pipe portion 312 for discharge, and the sewage does not need to go around the bottom of the first pipe portion 311 and then go up to the second pipe portion 312, thereby shortening the length of the sewage travel path, achieving the purpose of accelerating sewage discharge, and allowing the sewage to be quickly discharged from the drain assembly.

[0033] An elastic rubber 11 is provided at the connection between the drain body 1 and the wash basin, and the elastic rubber 11 is used to prevent water from seeping into the connection between the drain body 1 and the wash basin.

[0034] The water-passing body 3 includes a water-passing housing 31, a bottom cover 32, a water-passing member 33 and a top support member 34. The bottom cover 32 is detachably arranged at the bottom of the water-passing housing 31. After long-term use, the water-discharging assembly has the problem of solid impurities being deposited at the bottom cover 32. When solid impurities are deposited at the bottom cover 32, the bottom cover 32 can be disassembled and cleaned to avoid bacterial growth at the position. Specifically, the water-passing housing 31 and the bottom cover 32 are detachably connected by a threaded structure, and a sealing ring 321 is provided at the connection between the water-passing housing 31 and the bottom cover 32.

[0035] The water flow housing 31 and the bottom cover 32 are both made of light-transmitting materials. For example, the bottom cover 32 can be made of transparent plastic or other materials, so that the user can judge whether there is a problem of solid impurity precipitation by directly observing the water flow housing 31 and the bottom cover 32. When solid impurities are found to be precipitated on the bottom cover 32, the bottom cover 32 can be disassembled and cleaned, thereby eliminating the need to remove the entire drain assembly from the washbasin for cleaning, thereby achieving simple cleaning.

[0036] The water passing member 33 is clamped to the inner circumference of the water passing housing 31, and the water passing member 33 is provided with an internal thread connected to the drain body 1, and the water passing member 33 is provided with a plurality of water passing holes 331. The water passing member 33 is provided with a plurality of clamping plates 342 extending downward, and the water passing housing 31 is provided with a clamping groove 313 for the clamping plates 342 to clamp, and the cooperation between the clamping groove 313 and the clamping plate 342 realizes that the water passing member 33 and the water passing housing 31 cannot rotate relative to each other.

[0037] By setting an overflow channel at the basin wall of the wash basin, and connecting the overflow channel to the water hole 331, when the water in the wash basin is too full, the water can flow into the water hole 331 through the overflow channel, and then flow into the water overflow shell 31 through the water hole 331 and finally be discharged through the second pipe part 312. The overflow port of the traditional wash basin is connected to the external pipeline and then connected to the drain assembly of the utility model. The utility model can further improve the aesthetics through the above structure, can further save the volume of the drain assembly of the utility model, and realize the ultra-thin setting of the drain assembly of the utility model.

[0038] The top holding member 34 is disposed above the water passing member 33, and is provided with a guide hole 341 connected to the water passing hole 331. The portion of the top holding member 34 that is higher than the water passing housing 31 will be embedded in the bottom of the wash basin, and a plurality of guide holes 341 arranged in an array are provided at this position, and sewage flows into the water passing hole 331 through the guide holes 341, and is finally discharged through the second pipe portion 312.

[0039] The water-passing member 33 is made of metal, and the water-passing housing 31 and the water-passing member 33 are fixedly connected as one body by a secondary injection molding process. Specifically, the water-passing member 33 is placed in a mold, and then the water-passing housing 31 is cast and molded by the mold to achieve the fixed connection between the two. The water-passing housing 31 is an injection molded part, and the top holding member 34 can be fixedly connected to the water-passing housing 31 by an ultrasonic welding process, thereby ensuring the firmness of the connection between the water-passing housing 31, the water-passing member 33 and the top holding member 34, ensuring that the connection will not leak water, and realizing the ultra-thin design of the water-passing body 3.

[0040] The height adjustment range between the drain body 1 and the water-passing housing 31 is between 10 mm and 57 mm. Figure 5 As shown, the distance between the elastic rubber 11 of the drain body 1 and the lower surface abutting against the wash basin to the top support 34 of the water drain body 3 and the upper surface abutting against the wash basin is adjustable, and the adjustable height range is between 10mm-57mm, so that the drain assembly can be installed to adapt to wash basins with a basin bottom thickness within the range of 10mm-57mm, so that the drain assembly of the utility model can be adapted to wash basins of various specifications.

[0041] A water gap 314 is formed between the water housing 31 and the drain body 1, so that sewage can enter the second pipe part 312 through the water gap 314, thereby accelerating the drainage. According to actual measurements, the drainage flow rate of the drain assembly of the utility model can reach 0.63L / min.

[0042] The cover body 2 includes a sealing plate 21, a bouncing device 22 and a filter basket 23. The filter basket 23 is clamped in the drain body 1. The guide column 222 is used to drive the sealing plate 21 to float between closing and opening the opening of the drain body 1. The filter basket 23 is used to filter large solid impurities such as vegetable leaves to prevent them from falling into the water filter body 3.

[0043] Reference Figure 6 to Figure 7As shown, the bouncing device 22 includes a lifting shell 221, a guide column 222, a return spring 223 and a connecting hook 224. The lifting shell 221 is sleeved on the outer periphery of the guide column 222 and moves up and down along the guide column 222. One end of the connecting hook 224 is fixed to the lifting shell 221, and the other end of the connecting hook 224 slides in the guide groove provided in the guide column 222. The return spring 223 is provided between the sealing plate 21 and the lifting shell 221. The guide column 222 is threadedly connected to the sealing plate 21, and the lifting shell 221 is threadedly connected to the filter basket 23. The guide groove includes a first track 2221 and a second track 2222. The first track 2221 and the second track 2222 are connected at their ends, respectively. The first track 2221 and the second track 2222 are symmetrically arranged in a J-shape, and one end of the connecting hook 224 moves along the first track 2221 and the second track 2222. When the connecting hook 224 moves on the first track 2221 and stays at the bottom connection between the first track 2221 and the second track 2222, the sealing plate 21 is in the opening position of the closing drain body 1; when the connecting hook 224 moves on the second track 2222 and stays at the top connection between the first track 2221 and the second track 2222, the sealing plate 21 is in the opening position of the opening drain body 1.

[0044] Reference Figure 6 to Figure 7 As shown, the bouncing device 22 also includes a limit screw 225, and the guide column 222 is provided with a long groove 2223 for the limit screw 225 to be inserted into. The limit screw 225 is fixedly connected to the lifting shell 221. When the user presses the sealing plate 21, the lifting shell 221 moves, and the position of the sealing plate 21 is limited by the clamping position of the connecting hook 224. The cooperation between the limit screw 225 and the long groove 2223 limits the movement trajectory of the lifting shell 221 along the guide column 222, and the two will not rotate or misalign with each other. The lifting shell 221 protects the guide column 222 and can prevent impurities in the sewage from entering the bouncing device 22 and causing damage to it.

[0045] The second pipe part 312 is provided with an anti-backflow device 35. The anti-backflow device 35 includes a housing 351 and a flap 352. After the water flows through the second pipe part 312, the flap 352 will be driven to flip outward, and then discharged through the drainage pipe 4. The anti-backflow device 35 can prevent sewage from flowing back, and can prevent cockroaches, rats, etc. in the urban sewage pipe from crawling into the second pipe part 312. The anti-backflow device 35 is used to achieve the functions of preventing odor and overflow. The specific structure of the anti-backflow device 35 belongs to the prior art and will not be repeated here.

[0046] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes.
