Self-adhesive film self-closing odorless water-saving urinal

Abstract

The invention discloses a self-adhesive film self-closing odorless water-saving urinal. No water return elbow is formed in a drainage pipe under the drainage port of the urinal; the drainage port of the urinal is funnel-shaped; a film sealing air separation device is arranged in the drainage port; and no flushing ring is formed over the cavity of the urinal, but only one micro nozzle is arranged. The film sealing air separation device does not evaporate, return odor, accumulate water, scale or produce odor but completely discharges the urine so as to ensure easy flushing and low water consumption, namely only 0.25 to 0.5 L of water is used for every time after urinating; and the micro nozzle not only keeps the urinal away from peculiar smell, but also ensures extremely low water consumption during the flushing of the urinal. Because a flushing ring is eliminated and no water return elbow is formed, the urinal not only saves water during the flushing but also ensures simple structure, easy manufacturing and low cost.

Description

technical field [0001] The invention relates to a urinal, in particular to an odorless water-saving urinal which is automatically closed by the mucous membrane. Background technique [0002] With the shortage of global water resources, many water-saving urinals have appeared on the market. Although some have also played a certain water-saving effect, they generally have the following shortcomings: 1. Due to the dryness of the inner cavity of the urinal before use, It causes the inner cavity of the toilet to absorb urine, which in turn causes the peculiar smell to remain in the inner cavity of the toilet and cannot be removed; 2. Since the sewage pipe below the sewage outlet of the toilet is equipped with an S-shaped or P-shaped curved water-sealed and air-trap device, resulting in When flushing the toilet, not only the water is too much, but also the urine cannot be completely removed, which will cause dirt and fouling in the sewage outlet of the toilet, and produce foul sme...

[0002] With the shortage of global water resources, many water-saving urinals have appeared on the market.

Due to the dryness of the inner cavity of the urinal before use, It causes the inner cavity of the toilet to absorb urine, which in turn causes the peculiar smell to remain in the inner cavity of the toilet and cannot be removed; 2. Since the sewage pipe below the sewage outlet of the toilet is equipped with an S-shaped or P-shaped curved water-sealed and air-trap device, resulting in When flushing the toilet, not only the water is too much, but also the urine cannot be completely removed, which will cause dirt and fouling in the sewage outlet of the toilet, and produce foul smell; The curved water-sealed gas trap will lose its gas trap function due to the evaporation of water, causing the odor in the sewage pipe to recoil indoors, seriously polluting the indoor air

4. Since the toilet is equipped with a flushing circle and the sewage pipe is equipped with an S or P-shaped bend, not only the water consumption is large during flushing, but also the structure is complex, labor-intensive and costly to manufacture.
