Double-layer water seal micro-water flushing anti-freezing toilet bowl

Technical Field

The utility model belongs to the technical field of the sanitary wares technique and specifically relates to a little water of double-deck water seal washes squatting pan that prevents frostbite.

Background

At present, the rural toilet revolution is well developed in the country, and according to the toilet modification requirement, the modified toilet should realize the three-change standard of underground harmlessness, ground sanitation, convenient use and the like, namely, the requirements of cleanness, sanitation, no flies, convenient use, basic no odor of a toilet room and the like are met. At present, the traditional squatting (sitting) toilet is used in urban areas, because the infrastructure of the urban areas is perfect, the adequate water source is available for flushing, the heat preservation measures of the toilet room are good, and the problems of sanitation, deodorization, antifreezing, convenience in use and the like of the toilet are solved. After the squatting pan is put into a rural environment for use, the inadaptability of the traditional squatting pan (toilet) is gradually shown due to poor rural infrastructure conditions, inadequate heat preservation of a toilet room, untimely water supply and the like. In use, the pair of contradictions are formed between the deodorization and anti-freezing functions and the feces trafficability of the traditional toilet, and the toilet with good deodorization and anti-freezing functions is seriously frozen in winter, so that the normal use is influenced; the toilet with good excrement passing performance has poor deodorization function in summer and serious odor phenomenon in summer due to the open excrement leaking port, and mosquitoes and flies are easy to contact with excrement to spread diseases. These phenomena are particularly prominent in severe cold areas and water-deficient areas in the north of China. The sanitation problem after the rural toilet is transformed cannot be fundamentally solved, the problem of inconvenience in use in winter and the like is also caused, the problem is also an important reason that the work satisfaction of the public on the rural toilet revolution is not high, and the problem of deodorization, sanitation and winter anti-freezing of the rural toilet is solved to be the biggest problem which troubles the current toilet revolution.

The existing squatting (sitting) toilet is provided with a water storage tank with larger volume and an S-shaped bent plug at the rear part, and has higher requirements on heat preservation performance and water using conditions. Rural toilet rooms are generally relatively simple and crude, poor in heat preservation performance and untimely in water supply. When the S-shaped bent plugging part of the toilet stool and the water tank are used in most rural areas in the north of China in winter, the S-shaped bent plugging part of the toilet stool and the water tank are easy to freeze, and the toilet stool cannot be normally used or feces are exposed. The prior squatting (sitting) toilet is discharged from a straight port, and even if an odor-proof valve is installed, the effects of odor resistance and fly resistance are poor, so that the odor is heavier in summer and flies are prevented.

No matter the current squatting pan is hydrocone type or direct flushing type, the blow off pipe is crooked shape, seals the foul smell through the water head water storage, in order to make the excrement smoothly pass through horizontal S-shaped pipeline, needs great water consumption, generally need water 4 ~ 6 litres at least, even when washing urine, also need use the water of nearly a case, causes great water source extravagant.

The prior squatting (sitting) toilet can emit unpleasant smell in the use process, has no exhaust device, cannot eliminate peculiar smell and moisture, and needs to be additionally provided with a ventilation fan.

The existing squatting (sitting) toilet is often left with solid excrement on the port of the defecation channel and the wall of the toilet after use, especially in public places, the residual quantity is more after a long time, the toilet is extremely unsanitary, and a large amount of water is needed for flushing, and if a specially-assigned person is needed for cleaning, the labor is wasted.

Most of the existing squatting (sitting) toilets are made of ceramic products, have complex structures and high requirements on materials, not only have high production cost, but also do not meet the national energy-saving and emission-reduction response requirements due to the fact that a large amount of energy needs to be consumed in the firing process; and the transportation is difficult due to the characteristics of heavy volume and fragility. For the all stainless steel toilet, the manufacturing cost is high, so that the popularization is not facilitated; for the full-engineering plastic toilet bowl, because the surface of the toilet bowl is easy to scratch and the inherent defect of smooth finish, the difficulty of cleaning in normal use is increased, and the public recognition is low.

The existing squatting (sitting) toilet bowl with the turning plate plugging function also has the problem of multiple sanitation, and due to the internal structure, the direct contact between excrement and the turning plate cannot be avoided, and the residual excrement is easy to expose to form pollution. Some turn over the board and set up the cladding material, increase the ability of turning over the board anti-soil, but this kind of technical scheme effect is limited, and not only the coating cost is higher, and very easily appears the mar, and anti-soil function can decay along with the long-time extension of use.

The occasional bearing type squatting pan has high requirements on strength, high requirements on materials, inconvenient transportation and high manufacturing difficulty, and not only can improve the production cost, but also can improve the use cost. Most squatting toilets have unreasonable structural design, inconvenient maintenance and high replacement and maintenance cost.
