The working process and principle of the embodiment are as follows:

the water tank 4 is buried under the ground, and the water tank 4 is buried under the frozen soil layer in winter, so that the problem of freezing of the water tank of the rural toilet in winter can be effectively solved.

Personnel squat on two placing pieces 3, the weight of a user presses on an upper plate 31, the upper plate 31 extrudes an elastic bag 32, air in the elastic bag 32 enters a telescopic cylinder 52 through a guide pipe 2 and pushes the telescopic cylinder 52 to extend, the telescopic cylinder 52 drives a piston 53 and a balancing weight 55 to move upwards through a cross rod 51 and a vertical rod 56, water in a water tank 4 enters a shell 57 through a one-way valve 54, when the personnel leave the placing pieces 3, the piston 53 is driven to move downwards by the gravity of the balancing weight 55 and contracts the telescopic cylinder 52, gas in the telescopic cylinder 52 enters the elastic bag 32 through the guide pipe 2 to recover the shape of the elastic bag 32, the piston 53 enables the water in the shell 57 to wash the squatting pan 1 through a water pipe 6, and the squatting pan 1 is convenient to wash.

The gravitational potential energy of the personnel is converted and stored into the gravitational potential energy of the balancing weight 55, a water flow pressurizing device is not needed, and the device is simple and convenient.

The male person does not step on two placing pieces when urinating, and the back foot of urinating steps on one of them placing piece 3, then releases placing piece 3, realizes washing by water a small amount, practices thrift the water source.

Connect outside septic tank below squatting pan 1, sewage is at first discharged to the first order by the water inlet, and the great solids of proportion and thing such as worm's ovum precipitate in the one-level, utilize the preliminary fermentation decomposition of the thallus of pond aquatic, the sewage of passing through first order treatment can be divided into the three-layer: pasty fecal skin, relatively clear liquid manure and solid fecal slag;

the liquid dung after primary decomposition flows into the second stage, the liquid dung floating on the liquid dung and the liquid dung deposited on the liquid dung are left in the first stage for continuous fermentation, in the second stage, the liquid dung is continuously fermented and decomposed, worm eggs continue to sink, pathogens die gradually, the liquid dung is further harmless, and the thickness of the generated liquid dung and the liquid dung is less than that of the first stage;

the liquid manure that flows into the third stage is generally already decomposed, wherein germs and eggs are substantially killed, and the third stage functions mainly to temporarily store the settled and substantially harmless liquid manure, and to pass through a catch basin, an evaporation pit or a drainage pipeline through which the re-settled liquid manure is discharged through a drainage pipe.

Example two: as shown in fig. 4, the present embodiment discloses an anti-freezing dry toilet for rural areas, which has a structure substantially the same as that of the first embodiment, except that an annular sleeve 33 is sleeved outside an elastic bag 32 of the present embodiment, and the upper and lower ends of the annular sleeve 33 are fixedly connected with the side surface of an upper plate 31 and the side surface of a lower plate 34 respectively; the annular sleeve 33 is soft plastic material or soft rubber material, and the annular sleeve 33 avoids adhesion debris on the elastic bag 32, places the mode clearance that 3 washed or swept with water, and it is convenient to place 3 clearance.

The lower side of the upper plate 31 is fixedly connected with the upper end of a guide slide bar 36, the lower end of the guide slide bar 36 penetrates through the lower plate 34 and extends to the lower part of the lower plate 34, an opening matched with the guide slide bar 36 is fixed on the squatting pan 1, the upper plate 31 drives the guide slide bar 36 to slide towards the opening of the squatting pan 1 after being pressed, and an elastic part 35 is sleeved on the guide slide bar 36 between the upper plate 31 and the lower plate 34; personnel squat on two placing pieces 3, and guide slide bar 36 slides downwards, and guide slide bar 36 restricts upper plate 31 and can only slide up and down, avoids upper plate 31 lateral bending to guarantee personnel stand or squat the security on upper plate 31.

The elastic member 35 is an elastic sleeve or a spring, so that the upper plate 31 is conveniently moved upwards and restored.

Example three: as shown in fig. 1, the present embodiment discloses an anti-freezing dry toilet for rural areas, which has a structure substantially the same as that of the first embodiment, except that a water pipe one-way valve for preventing water from flowing downwards is installed on a water pipe 6 of the present embodiment.
