[0004] Control method of RV-style public toilet. If the infrared sensor lighting will automatically turn on at night, the toilet user stands on the electric spiral lift in front of the RV, and then presses the lifting button. The electric spiral lift stops rising after reaching the set height. The toilet user scans the QR code with a mobile phone to pay the access control and payment, and the RV door opens automatically. The toilet user enters the RV, closes the door, sits on the toilet, or squats on the squat pit to urinate. After the convenience is over, open the door, walk to the electric spiral lift, and then press the lifting button. After the electric spiral lift drops to the ground, the electric spiral lift stops descending and the RV door closes automatically. There is an infrared sensor in the RV that detects that the toilet user has left, and the computer controller will power on the grey water pump and power on the grey water electromagnetic outlet valve of the toilet. The grey water pump extracts grey water from the stainless steel grey water tank, and the water in the stainless steel biogas tank passes through the stainless steel biogas tank side wall and the stainless steel grey water tank. There is a dense stainless steel filter between the stainless steel biogas tank and the stainless steel grey water tank to replenish the stainless steel grey water tank. The particles of the high molecular organic polymer purifier with a large number of hydrophilic hydroxyl groups in the stainless steel medium water tank adsorb small molecular organic matter, so that the water in the stainless steel medium water tank no longer contains small molecular organic matter and becomes medium water. The medium water in the stainless steel medium water tank passes through the medium water pump and the medium water electromagnetic outlet valve of the toilet that is powered on to flush the toilet, and then the computer controller stops powering the medium water pump and the medium water electromagnetic outlet valve of the toilet, and closes the medium water electromagnetic outlet valve of the toilet. There is an infrared sensor in the RV to detect that the squat toilet has left, and the computer controller will power on the medium water pump and power on the medium water electromagnetic outlet valve of the squat toilet. The medium water pump extracts medium water from the stainless steel medium water tank, and the water in the stainless steel biogas tank passes through the stainless steel biogas tank side wall and the stainless steel medium water tank. There is a dense stainless steel filter between the stainless steel medium water tank and the stainless steel medium water tank to replenish the stainless steel medium water tank. The particles of the high molecular organic polymer purifier with a large number of hydrophilic hydroxyl groups in the stainless steel medium water tank adsorb small molecular organic matter, so that the water in the stainless steel medium water tank 7 no longer contains small molecular organic matter and becomes medium water. The water in the stainless steel water tank 7 is replenished into the stainless steel water tank through the water pump and the water in the stainless steel biogas tank, and the stainless steel water tank is passed through the stainless steel filter screen between the side wall of the biogas tank and the stainless steel water tank. The water in the stainless steel water tank is flushed into the squat pit through the water pump and the electromagnetic water outlet valve of the squat pit 1 that is powered on. Then the computer controller will stop supplying power to the water pump and the electromagnetic water outlet valve of the squat pit 1, and close the electromagnetic water outlet valve of the squat pit 1. The excrement from the sewer pipe of the toilet or squat pit flows into the feces box. When the computer controller detects that the liquid level in the feces box is higher than the set value through the liquid level sensor probe installed in the feces box, the computer desk instrument will start the screw extrusion pump, and the excrement squeezed out of the screw extrusion pump body passes through the feces one-way valve and enters the top of the stainless steel biogas tank. The excrement in the stainless steel biogas box and the water in the stainless steel water tank no longer contain small molecular organic matter and ferment to produce biogas at 55°C. When the liquid level sensor of the stainless steel biogas tank detects that the liquid level inside the stainless steel biogas tank is higher than the set value, the computer controller will start the grey water pump and power on to open the grey water electromagnetic drain valve.The water pump draws out the water in the stainless steel water tank, and the water in the stainless steel biogas tank passes through the stainless steel filter screen between the side wall of the biogas tank and the stainless steel water tank 7 to be added to the stainless steel water tank. The large amount of hydrophilic hydroxyl high molecular organic polymer purifier particles in the stainless steel water tank adsorb small molecular organic matter, so that the water in the stainless steel water tank no longer contains small molecular organic matter and becomes water. The water in the stainless steel water tank is discharged to the lawn of the green belt through the water pump and the electromagnetic drain valve of the water that is powered on. When the liquid level sensor of the stainless steel biogas tank detects that the liquid level in the stainless steel biogas tank is lower than the set value, the computer controller will stop powering the water pump and the electromagnetic drain valve of the water, and close the electromagnetic drain valve of the water. The fermented feces in the stainless steel septic tank passes through the coarse stainless steel filter at the bottom of the stainless steel biogas tank and enters the stainless steel septic tank. When the liquid level sensor of the stainless steel biogas tank detects that the liquid level in the stainless steel biogas tank is higher than the set value, and the set time is reached, the feces in the stainless steel septic tank needs to be cleaned regularly. The feces suction truck is driven to the RV-style public toilet, and the feces suction pipe of the feces suction truck is connected to the outlet of the manual feces butterfly valve. The manual feces butterfly valve and the manual valve of the feces suction truck are opened, and the vacuum pump of the feces suction truck starts to work to suck the feces in the stainless steel septic tank into the feces suction truck. When the liquid level sensor of the stainless steel biogas tank detects that the liquid level in the stainless steel biogas tank is lower than the set value, the feces in the stainless steel septic tank is sucked away and the manual feces butterfly valve is closed. After the feces suction pipe of the feces suction truck is put away, the manual valve of the feces suction truck is closed, and the manual valve of the feces suction truck is closed, and then the vacuum pump of the feces suction truck stops working. The sewage in the stainless steel septic tank flows through the dense stainless steel mesh at the bottom of the stainless steel septic tank to the stainless steel sewage tank.

The computer controller will start the sewage pump, and the sewage pump pumps the sewage in the stainless steel sewage tank to the stainless steel biogas tank. After the set time is reached, the computer controller will stop supplying power to the sewage pump. When the biogas concentration sensor probe installed in the stainless steel biogas tank detects that the biogas concentration in the stainless steel biogas tank reaches the set value, the computer controller will start the electric electric regulating air valve, and the biogas in the stainless steel biogas tank passes through the electric electric regulating air valve into the biogas combustion furnace and is ignited by the electronic spark plug. The computer controller starts the electric blower, and the electric blower sucks the air from the toilet into the biogas combustion furnace to provide support for biogas combustion. The hot air coming out of the biogas combustion furnace passes through the electric regulating reversing air valve. The computer controller adjusts the electric regulating reversing air valve according to the value of the liquid temperature in the stainless steel biogas tank detected by the temperature sensor probe in the stainless steel biogas tank below 55°C. In summer, adjust the manually adjustable reversing air valve to close the toilet heating pipe valve and open the toilet external air pipe valve. In summer, the hot air from the biogas burner passes through the electric adjustable reversing air valve, passes through the stainless steel heating pipe in the stainless steel biogas tank, and is discharged from an activated carbon tank.In summer, the hot air from the biogas burner passes through the other outlet of the electric adjustable reversing air valve, enters the manual adjustable reversing air valve, and is discharged from an activated carbon tank.

In winter, the hot air from the biogas burner passes through the other outlet of the electric adjustable reversing air valve, enters the manual adjustable reversing air valve, passes through the heating pipe in the toilet, and is discharged from another activated carbon tank. When the temperature sensor probe in the stainless steel biogas tank detects that the temperature inside the stainless steel biogas tank is higher than the set value, the computer controller will reduce the amount of hot air from the electric adjustable reversing air valve to the stainless steel heating pipe in the stainless steel biogas tank. When the temperature sensor probe in the stainless steel biogas tank detects that the temperature inside the stainless steel biogas tank is lower than the set value, the computer controller will increase the amount of hot air from the electric adjustable reversing air valve to the stainless steel heating pipe in the stainless steel biogas tank.

The grey water pump (12) is electrically started and the grey water electromagnetic outlet valve (14) of the toilet (2) is electrically opened. The grey water pump (12) extracts grey water from the stainless steel grey water tank (7). The water in the stainless steel biogas tank (6) passes through a dense stainless steel filter between the side wall of the stainless steel biogas tank (6) and the stainless steel grey water tank (7) and is added to the stainless steel grey water tank (7). A large amount of hydrophilic hydroxyl high molecular organic polymer purifier particles in the stainless steel grey water tank (7) adsorb small molecular organic matter, so that the water in the stainless steel grey water tank (7) no longer contains small molecular organic matter and becomes grey water. The grey water in the stainless steel grey water tank (7) passes through the grey water pump (12) and the grey water electromagnetic outlet valve (14) of the toilet (2) that is electrically opened to flush the toilet (2). After that, the computer control instrument will stop supplying power to the grey water pump (12) and the grey water electromagnetic outlet valve (14) of the toilet (2), and close the grey water electromagnetic outlet valve (14) of the toilet (2); when the infrared sensor in the RV detects that the person who used the squatting pit (1) has left, the computer control instrument will start the grey water pump (12) and open the grey water electromagnetic outlet valve (14) of the squatting pit (1), and the grey water pump (12) will draw grey water from the stainless steel grey water tank (7), and the water in the stainless steel biogas tank (6) will be replenished into the stainless steel grey water tank (7) through the dense stainless steel filter between the side wall of the stainless steel biogas tank (6) and the stainless steel grey water tank (7), and the large amount of hydrophilic hydroxyl high molecular organic polymer in the stainless steel grey water tank (7) will be The particles of the purifier absorb small molecular organic matter, so that the water in the stainless steel grey water tank (7) no longer contains small molecular organic matter and becomes grey water. The grey water in the stainless steel grey water tank (7) passes through the grey water pump (12) and the water in the stainless steel biogas tank (6) and passes through a dense stainless steel filter between the side wall of the stainless steel biogas tank (6) and the stainless steel grey water tank (7) to be replenished into the stainless steel grey water tank (7). The water in the stainless steel grey water tank (7) passes through the grey water pump (12) and the grey water electromagnetic outlet valve (14) of the squat pit (1) that is powered on and opened to flush the squat pit (1). Then, the computer controller stops supplying power to the grey water pump (12) and the grey water electromagnetic outlet valve (14) of the squat pit (1), and closes the grey water electromagnetic outlet valve (14) of the squat pit (1).Excrement from the sewer pipe of the toilet (2) or squatting pit (1) flows into the feces box (3). When the computer control instrument detects through the liquid level sensor probe installed in the feces box (3) that the liquid level in the feces box (3) is higher than the set value, the computer control instrument will start the screw extrusion pump (4), and the excrement squeezed out from the screw extrusion pump body passes through the feces one-way valve (5) and enters the top of the stainless steel biogas box (6); the excrement in the stainless steel biogas box (6) and the water in the stainless steel intermediate water tank (7) no longer contain small molecular organic matter and ferment at 55°C to produce biogas. When the liquid level sensor of the stainless steel biogas box (6) detects that the liquid level in the stainless steel biogas box (6) is higher than the set value, the excrement in the stainless steel biogas box (6) is turned off. When the set value is reached, the computer controller starts the grey water pump (12) and opens the grey water electromagnetic drain valve (13) by powering on. The grey water pump (12) pumps out the grey water in the stainless steel grey water tank (7). The water in the stainless steel biogas tank (6) passes through the stainless steel filter screen between the side wall of the stainless steel biogas tank (6) and the stainless steel grey water tank (7) and is added to the stainless steel grey water tank (7). The large amount of hydrophilic hydroxyl high molecular organic polymer purifier particles in the stainless steel grey water tank (7) adsorb small molecular organic matter, so that the water in the stainless steel grey water tank (7) no longer contains small molecular organic matter and becomes grey water. The grey water in the stainless steel grey water tank (7) passes through the grey water pump (12) and the electromagnetic drain valve (13) opened by powering on. The solenoid drain valve (13) drains the grey water onto the lawn of the green belt; when the liquid level sensor of the stainless steel biogas tank (6) detects that the liquid level in the stainless steel biogas tank (6) is lower than the set value, the computer controller stops supplying power to the grey water pump (12) and the solenoid drain valve (13), and closes the solenoid drain valve (13); the fermented feces in the stainless steel septic tank (6) passes through the coarse stainless steel filter at the bottom of the stainless steel biogas tank (6) and enters the stainless steel septic tank (8); when the liquid level sensor of the stainless steel biogas tank (6) detects that the liquid level in the stainless steel biogas tank (6) is higher than the set value, and the stainless steel biogas tank needs to be cleaned regularly at the set time, The feces in the feces tank (8) are sucked out, the feces suction truck is driven to the RV-type public toilet, the feces suction pipe of the feces suction truck is connected to the outlet of the manual feces butterfly valve (9), the manual feces butterfly valve (9) and the manual valve of the feces suction truck are opened, and the vacuum pump of the feces suction truck starts to work to suck the feces in the stainless steel septic tank (8) into the feces suction truck, when the liquid level sensor of the stainless steel biogas tank (6) detects that the liquid level in the stainless steel biogas tank (6) is lower than the set value, the feces in the stainless steel septic tank (8) is sucked away and the manual feces butterfly valve (9) is closed, the feces suction pipe of the feces suction truck is put away and the manual valve of the feces suction truck is closed, the manual valve of the feces suction truck is closed, and then the vacuum pump of the feces suction truck stops working;The sewage in the stainless steel septic tank (8) flows through the dense stainless steel mesh at the bottom of the stainless steel septic tank (8) to the stainless steel sewage tank (10). The sewage in the stainless steel sewage tank (10) needs to be pumped into the stainless steel biogas tank (6) at regular intervals to stir the excrement fermented in the stainless steel biogas tank (6) and generate more biogas. The computer controller will start the sewage pump (11), and the sewage pump (11) pumps the sewage in the stainless steel sewage tank (10) into the stainless steel biogas tank (6).
