Description

Rural portable lavatory

Technical Field

The utility model relates to a toilet, which is applied to the technical occasion that the countryside does not have sufficient tap water for flushing.

Background

Rural water resources in western regions of China are deficient, the toilet is mainly a dry toilet, and the problems of serious environmental pollution, water resource waste, easy frost cracking and frost damage of a water storage barrel in winter and the like exist when the dry toilet is used.

"rural happy strategy planning (2018 and 2022)": the method implements the toilet revolution, combines the practical popularization of different types of sanitary toilets in various places, and promotes the harmless treatment and resource utilization of toilet excrement. How to advance the toilet revolution under the actual condition of extremely deficient water resources in the western region provides a safe, environment-friendly and pollution-free toilet use environment for the masses in rural areas, and is a technical problem which needs to be solved urgently.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a rural portable lavatory that water resource use is few, can both use in each season in western rural area easily.

In order to realize the purpose, the invention adopts the technical scheme that: the rural portable toilet comprises a urinal and a water storage tank, wherein a sewage conveying pipe is fixed below the urinal, a plurality of nozzles are symmetrically arranged on the periphery of the inner wall of the urinal, each nozzle is connected with the water storage tank through a one-way air stop valve, the water storage tank is a closed box body with a cover, the water storage tank is provided with the one-way air stop valve, a high-pressure air pump is connected with a ball valve and an electromagnetic valve in parallel, the ball valve is connected with the nozzle, and the electromagnetic valve is connected with the water storage tank.

In the scheme, the electromagnetic valve and the ball valve are controlled by the same PLC.

In the scheme, the urinal and the sewage conveying pipe are connected through an iron reverse cross air pipe, one end of the iron reverse cross air pipe is connected with an outlet of the urinal in a sealing mode, the end face of the other end of the iron reverse cross air pipe is an inclined face, and the magnet plate is installed on the inclined face through a hinge.

The invention has the beneficial effects that: (1) according to the invention, the plurality of nozzles are symmetrically arranged in the urinal, when the urinal works in summer, the high-pressure air pump supplies high-pressure air to each nozzle through the ball valve, the water storage tank is communicated with the external atmosphere through the one-way air stop valve, and under the action of the siphon principle, water in the water storage tank breaks the pressure limit of the one-way air stop valve, so that the water is sprayed out of the nozzles, the excrement in the urinal is flushed into the sewage conveying pipe, the using amount of the flushing water can be greatly reduced, and the purpose of saving water resources is achieved; (2) in winter, the electromagnetic valve is automatically opened after the urinal is flushed each time in winter, and high-pressure gas provided by the high-pressure gas pump is sprayed to the nozzle from the closed water storage tank, so that the residual water in the flushing pipeline is sprayed into the urinal from the nozzle, and the flushing pipeline is prevented from being frozen; (3) through the anti-stringing pipe of installation iron between urinal and defeated dirty pipe, when excrement and urine was washed the anti-stringing pipe bottom of iron, rely on faecal gravity to open ferromagnetic plate, treat that excrement and urine falls back into defeated dirty intraductal back, ferromagnetic plate relies on magnetic force to attract again with the anti-tracheal inclined plane laminating of string of iron together to the foul smell in having avoided defeated dirty causes air pollution to the user of urinal annex.

Detailed Description

The technical solution of the present invention will be described in more detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the rural portable toilet provided by the embodiment comprises a urinal 1, a sewage conveying pipe 2 is fixed below the urinal 1, four nozzles 3, namely a nozzle a, a nozzle B, a nozzle C and a nozzle D, are symmetrically installed around the inner wall of the urinal 1, as shown in fig. 3, a ball valve 6 and an electromagnetic valve 5 are connected in parallel to a high-pressure air pump, the ball valve 6 is connected with the nozzle 3, and the electromagnetic valve 5 is connected with a water storage tank. The electromagnetic valve 5 and the ball valve 6 are controlled by the same PLC controller. As shown in fig. 4, the nozzle a, the nozzle B, the nozzle C and the nozzle D are all connected with the water storage tank through one-way air stop valves, the water storage tank is a closed tank body with a cover, and the one-way air stop valves are installed on the water storage tank; as shown in fig. 5, the urinal 1 and the dirt conveying pipe 2 are connected through an iron reverse cross air pipe 7, one end of the iron reverse cross air pipe 7 is hermetically connected with an outlet of the urinal 1, the end surface of the other end of the iron reverse cross air pipe 7 is an inclined surface, and a magnet plate 8 is mounted on the inclined surface through a hinge.

The use process of the rural portable toilet provided by the embodiment is as follows: the user finishes after convenient in 1 urinal, triggers the PLC controller, PLC controller control ball valve 6 is slowly opened, prevent that gas from getting into rapidly and splashing out, through the siphonage behind the entering shower nozzle, with the shower nozzle of inhaling in the very short time of the few water in the storage water tank, water tank one end is equipped with one-way air stop valve, can the folk prescription for the water tank provides atmospheric pressure, because the water tank is airtight space, atmospheric pressure is uneven and can't inhale water when preventing the siphonage. The water and the air are mixed and then are sprayed out from the spray head, and the flushing of the urinal is finished. And a one-way air stop valve is arranged at the inlet of each spray head to prevent water from automatically flowing into the spray heads due to gravitational potential energy. When the excrement in the urinal 1 is flushed to the bottom of the iron anti-cross air pipe 7, the ferromagnetic plate 8 is opened by means of the gravity of the excrement, and after the excrement falls back into the excrement conveying pipe 2, the ferromagnetic plate 8 is attached to the inclined surface of the iron anti-cross air pipe 7 again by means of magnetic attraction, so that air pollution of odor in the excrement conveying pipe 2 to users attached to the urinal 1 is avoided. In order to prevent the water pipe and the water tank from being frozen in winter, after the flushing in winter is finished, the electromagnetic valve is opened, gas in the high-pressure gas pump is input into the water tank, high-pressure gas enters the flushing pipeline through the water tank, water omitted in the water tank and the flushing pipeline is sprayed out from the nozzle, and meanwhile when the gas is introduced into the flushing pipeline for drainage, the one-way gas stop valve arranged at the position of the spray head can prevent the gas flowing out of the flushing pipeline from entering the gas pipe to cause backflow.
