Description

Technical Field

[0001] The utility model belongs to the field of vertical or wall-mounted urinals, in particular to a urinal drainage device. Background Art

[0002] Urinals are mostly used in toilets in public buildings such as shopping malls, parks, and hotels. They can also be used in home toilets. After urinating in the urinal, the user needs to press the button next to the urinal. The solenoid valve will open the water valve through the suction action between the electromagnets, and water will flow into the urinal to flush it. When a certain amount of water flows in, the solenoid valve will close again to achieve the purpose of saving water.

[0003] In the prior art, the urinal drainage device is easily clogged. These blockages are mainly formed by the accumulation of impurities, the gradual accumulation of fallen hair on burr steps, and the crystals formed after urine adheres to the inner wall of the pipe and the steps and evaporates. The water in the pipe above the water surface in the drainage pipe is easy to evaporate and cause crystallization, while the water marks inside the water seal and subsequent pipes are not easy to evaporate and crystallize due to the existence of the water seal. Since the crystals appear at the front end of the drainage pipe water seal, it is difficult to soak the crystals for a long time with acid and it is difficult to completely rinse them with acid. Therefore, the impurities such as scale, urine alkali and hair accumulate in the drainage pipe at a faster speed, which requires frequent manual treatment, which increases the workload of the cleaning staff and also affects the service life of the urinal if it is not cleaned for a long time.

[0004] Some patents of urinals are disclosed in the prior art, among which the utility model patent with the announcement number CN220167081U discloses a urinal, including an inner tank and a sewage pipe, the bottom of the inner tank is provided with a sewage outlet, the top of the rear end of the inner tank is provided with a water outlet, a guide step is provided between the water outlet and the sewage outlet, the front end of the guide step is located at the front side of the inner tank, and the rear end of the guide step is located below the water outlet; the sewage pipe is connected with the sewage outlet. Although the water flow is guided by the upper surface of the guide step and flows to the front side of the inner tank so that the front side of the inner tank can be flushed, and the problem that the water flow flushing surface in the traditional urinal is small and it is difficult to flush the front side of the inner tank is solved, the precipitation of hair and urea crystals will continue to occur, so there is still a problem that the upper end surface of the water seal in the drain pipe has crystal precipitation and needs frequent descaling.

[0005] In view of this, the inventor conducted in-depth research on how to reduce the precipitation of urea-alkali crystals on the upper end surface of the water seal and eliminate the need for frequent cleaning of the inside of the drainage pipe, which led to the present case.
