Description

Urinal without flushing

Technical Field

The utility model belongs to the technical field of bathrooms, and particularly relates to a water-free urinal.

Background

The toilet revolution greatly improves the toilet environment in rural areas, but blindly pushing the water-flushing toilet brings many problems, such as inconvenience in water use (lack of water supply and drainage pipe networks and easy freezing in winter) in most northern rural areas, water resource waste caused in arid water-deficient areas, frequent cleaning of septic tanks in a rear-end pollutant treatment mode, increase of later-stage use cost of farmers, inconvenience in returning and recycling of farmers to fields, even pollution of underground water and surrounding environment, difficulty in meeting the toilet environment requirement of sanitary toilets and the like, so that the willingness of the farmers to change toilets is insufficient in many areas, and the unwilling use situation is improved.

Based on the principle of adapting to the local conditions, the ecological dry toilet can be suitable for most of regions with inconvenient water use, and the excrement and urine diversity type toilet is one of the common ecological dry toilet forms.

In human feces, there are as many as hundreds of pathogenic microorganisms, such as salmonella, escherichia coli, ascarid eggs, schistosome, etc., and urine contains less pathogens due to the filtering action of the kidney compared to feces. A large amount of nitrogen, phosphorus and potassium in the domestic sewage are derived from urine and can be used as high-quality agricultural fertilizer, but if the excrement and the urine are directly fertilized after being mixed, pathogenic microorganisms in the excrement can cause potential harm to human health, so that the excrement and the urine are separately collected, the reduction and harmless treatment of the excrement and the urine are facilitated, and the efficient resource utilization by farmers is facilitated.

How to improve fecaluria diversity efficiency, reduce excrement and urine, urine and mix, reduce purchase, installation, use cost to it is the problem that this kind of ecological toilet need be solved to make clear drawing the product to the environmental impact less.

Because the urination posture of men and women is different, the standing posture of men and women is easy to cause the condition that urine around a toilet bowl splashes outwards when the men and women urinate into the toilet bowl (squatting pan or toilet bowl), so that peculiar smell can be generated to attract mosquitoes, the use experience is influenced, the cleaning burden is increased, and the breeding of bacteria can cause sanitation hidden troubles.

Therefore, urine of men needs to be collected independently, so that the efficiency of collecting the excrement and the urine can be improved, and the toilet experience can be improved.

In order to solve the problems, the common toilet bowl on the market at present mainly has the following structure:

this scheme of CN 103981936A is public latrine mainly to the use scene, and its purpose is in order to improve the embarrassment that public latrine man urinal interval distance brought when near experience like the lavatory, improves privacy like the lavatory, shortens the distance of two adjacent urinals through changing like the appearance of standing of lavatory person simultaneously to improve the space utilization between the lavatory.

The scheme needs to be packaged separately, the transportation space is large, and the transportation cost is high. The front edge of the urine receiving area is bowl-shaped, and residual urine can flow to the bottom of the toilet stool along the outer wall below the toilet stool, so that urine stains are easy to breed and the toilet stool is inconvenient to clean. The clean dead angle of this scheme is more, remains the urine stain easily, breeds the bacterium.

In summary, the drawbacks of the prior art mainly include the following:

1. the volume is too large, and the toilet is not suitable for domestic toilets in rural small spaces.

2. The mounting is not flexible.

3. The urine receiving area extends out short, and residual urine is easy to drop on the ground.

4. The residual urine flows to the bottom of the toilet bowl along the outer wall of the urine receiving area.

5. Is inconvenient to transport.

The flush-free urinal mainly comprises a rear wall, a rear side wall, a front side wall and a urine receiving area, wherein two sides of the rear wall are obliquely extended to form the rear side wall, the rear side walls on two sides are inwardly extended to form the front side wall, the lower ends of the rear wall, the rear side wall and the front side wall are inwardly extended and sealed to form the urine receiving area, and the included angle of the cross section of the rear side wall on two sides is 90-93 degrees; the urine outlet comprises a foreign matter prevention grid and a catheter, the lowest point of the urine receiving area is the urine outlet, the foreign matter prevention grid is arranged at the top of the urine outlet, and the catheter is arranged at the lower part of the urine outlet.

The upper ends of the rear wall, the rear side wall and the front side wall are gradually inclined downwards to form an opening, the junction of the two front side walls is the front edge of a urine receiving area, and the edge of the front edge of the urine receiving area is an everting lip structure.

The upper ends of the rear wall, the rear side wall and the front side wall are outwards provided with outward turning edges, and the outward turning edges of the rear wall and the rear side wall are provided with convex mounting lugs.

The included angle of the cross sections of the front side walls at the two sides is less than 90 degrees, and the front edge of the urine receiving area extends forwards and outwards.

The urine receiving area is of an arc bowl-shaped structure.

The rear wall, the rear side wall, the front side wall, the urine receiving area and the catheter are of an integrated structure.

The rear wall, the rear side wall and the front side wall extend outwards from bottom to top, and the barrel body is of a structure with a wide upper part and a narrow lower part.

And (3) diversity of feces and urine: a mode of separately collecting excrement and urine is convenient for independently treating the excrement and the urine, and is one of common toilet forms of an ecological toilet.

Thus, the application has the advantages that: the matched excrement and urine collecting and separating toilet bowl is used for rural families, and is small in size, low in production, transportation and installation cost and low in requirement on installation space, so that the efficiency of excrement and urine collecting and separating can be improved, and the toilet experience can be improved.
