Technical Field

The invention relates to the technical field of urinals, in particular to a directional super-lyophobic waterless self-cleaning urinal and a manufacturing method thereof.

Background

Modern public health facilities have extended the average human life by 20 years over the past 200 years. The toilet is one of basic sanitary facilities necessary for life and health of people, is a mark representing quality of life and taste, and 11 months and 19 days every year are defined as "world toilet days".

The "toilet revolution" has led people to become aware that the sanitation and hygiene of toilets is of great importance in establishing healthy lifestyle habits. Most of the odor of the toilet is from the residual urine and the splash of the urine in the urinal and the urinal, so how to develop the urinal and the urinal which have the advantages of self cleaning, no odor and no water treatment has very important economic value and social significance.

The patent of urinal for realizing self-cleaning function generally adopts a physical mode, for example, patent CN201310656224.3 discloses a self-cleaning anti-blocking odour-proof device and a toilet stool, a flexible hose and a directional reducing trap are used, so that water flow or urine generates micro motion in the discharge process, and the water flow or urine can be smoothly guided to a sewer pipe, thereby preventing collagen in the urine from being accumulated in the directional reducing trap, and generating condensed solids along with the lengthening of time to cause unsmooth discharge.

At present, the deodorizing and cleaning urinal announced in the market mainly realizes the deodorizing function by the surface coating nano-coating technology. However, these techniques require water to flush urine to remove odors, and have limited self-cleaning and odor-free effects, so that it is of great economic and social importance to develop urinals and urinals having self-cleaning, odor-free, and water-free treatments.
