Description

Technical Field

[0001] The present invention relates to the technical field of sanitary ware, and in particular to a toilet bowl, a tube membrane installation device and an excrement treatment method. Background Art

[0002] Saving water resources and reducing environmental pollution are important issues in the current environmental protection field. Since ordinary flush toilets consume a lot of water resources and the process of treating excrement also causes environmental pollution, waterless toilets have become a research focus in the field of environmental protection technology.

[0003] There are four main types of waterless toilets: the first is an incineration toilet, which has a combustion chamber at the bottom. The high temperature of 600°C in the combustion chamber is used to burn feces into fecal ash and water vapor. The toilet discharges the water vapor through a pipe, and the fecal ash falls into a collection box for regular treatment. The second is a urine and feces separation toilet, which separates the urinal area and the defecation area. Urine is discharged into the urine collection trough through the urinal area and is cleaned regularly, while feces is transported to a feces mixer through a drum for biological fermentation. The third is a nano-membrane toilet, which uses a nano-membrane to block odors and a special rotating mechanism to separate water from urine for recycling. The remaining compounds are combined with solid waste and converted into ash and energy through incineration or biological fermentation. The fourth is a storage bag toilet, which uses a storage bag to collect and package excrement for regular treatment.

[0004] The first three types of waterless toilets mentioned above are not tightly sealed during use, which easily produces odor. The feces-urine diverting toilet has a complicated process of separating liquid and solid, and the design of two collection devices increases the volume of the toilet. The incineration process of the incineration toilet will cause environmental pollution. The incineration toilet and nano-membrane toilet are complicated to handle and expensive.

[0005] Existing storage bag type toilets usually have storage bag cutting, bag opening and bagging structures inside the toilet, which makes the internal structure of the toilet complex and the toilet volume large; and because the storage bag cannot completely fit the inner wall of the toilet cavity, the user experience is poor.
