The operation process of the intelligent sewage disposal device provided by the embodiment is as follows:

in the original state (i.e. when no sewage discharge operation is started yet), the water outlet of the water pump 4 is divided into two parts: one part of the water path controller 3 is used for flushing the toilet bowl, the other part is connected into the energy storage tank 6 through the check valve, and the energy storage tank 6 is used for triggering high-pressure water of the water path controller 3. The water pump 4 has the advantages that the water outlet is divided into two parts: firstly, the water quantity used by the toilet flushing is more than the water quantity used by the trigger waterway controller 3, so that the high-pressure water triggering the waterway controller 3 can be ensured not to lose pressure when the toilet flushes, and the waterway controller 3 is ensured to be normally started; second, when water supply is stopped at home, the energy storage tank 6 stores high-pressure water, and the waterway controller 3 can be triggered to be opened, so that the high-pressure water in the interface valve 7 is released through the waterway controller 3, the interface valve 7 is opened, and the toilet is still normally used.

In the original state, the energy storage tank 6 is filled with high-pressure water, and the interface valve 7 is closed because the waterway controller 3 is filled with the high-pressure water; the water inlets of the button water valve 1 and the negative pressure water valve 2 are connected with high-pressure water for standby. The battery 15 supplies power to the components, and even if the power is off, the toilet can normally flush the stool 300 times, and the power adapter charges the battery. The negative pressure fan assembly 14 is not in operation and is in a standby state; no negative pressure exists in the negative pressure cavity assembly 8 a; the flip cover drain valve assembly 8b is in a closed and sealed state by the attraction of the magnet to the flip cover 8b 02. The turnover plate of the anti-backflow floor drain 8a09 is also in a closed state, and the air duct is airtight; the turning plate of the interface valve 7 is also in a closed state, so that the odor of the sewer cannot enter the toilet.

When the water and electricity are in normal cleaning, the urine needs to be cleaned: when the button water valve 1 is pressed down, the water outlet of the button water valve 1 instantly releases high-pressure water to enter the waterway controller 3 through the energy storage tank 6, the waterway controller 3 is triggered to be instantly opened, at the moment, the second water flushing port of the waterway controller 3 is filled with water, and the three high-pressure spray heads 10 start to spray water, so that the toilet bowl is cleaned; the interface valve drain of the waterway controller 3 is also opened, high-pressure water in the interface valve 7 is released into the overflow cavity 8 through the interface valve drain of the waterway controller 3, and the interface valve 7 is opened. The button water valve 1 is loosened, the high-pressure water at the water outlet of the button water valve 1 is disconnected, the other interface at the bottom of the waterway controller 3 is connected with the throttle valve 11, the high-pressure water filled in the cavity at the bottom of the waterway controller 3 is slowly released through the throttle valve 11, the time is called a time delay process, and the waterway controller 3 slowly recovers in the time delay process.

In the process, the waterway of the intelligent sewage disposal system is changed as follows:

the second flushing port of the waterway controller 3 is opened, and three high-pressure sprays 10 start spraying water; the interface valve water drain of the waterway controller 3 is opened, high-pressure water in the interface valve 7 is released through the interface valve water drain of the waterway controller 3, and the turning plate of the interface valve 3 is opened;

the interface valve water drain port of the waterway controller 3 is closed, and the interface valve 7 water drain outlet is locked;

the second water flushing port of the waterway controller 3 is used for water, and three high-pressure spray heads 10 are used for spraying water to flush the inner surface of the toilet;

the second flushing port of the waterway controller 3 is disconnected, the first flushing port is communicated with water, the joint at the bottom of the toilet liner is communicated with water, and the bottom of the toilet liner is flushed;

the first flushing port of the waterway controller 3 is disconnected, water is not sprayed at the bottom of the toilet liner, high-pressure water only passes through the filling interface valve 7 of the waterway controller 3, the interface valve 7 is closed again, and the system is restored to the initial state.

When the water and electricity are in a normal clear condition, the excrement needs to be cleaned: the electric button 12 is pressed down, the negative pressure fan assembly 14 is started rapidly, under the high-speed rotation of the high-pressure fan, air in the negative pressure cavity assembly 14 is sucked into the exhaust end of the fan, under the action of wind pressure, the flip cover of the anti-backflow floor drain 8a09 is opened, the air passes through the flip cover and enters the air channel at the bottom of the cavity, and finally, the air enters the sewer through the exhaust channel of the flap drain valve assembly 8 b. This will allow the interior of the toilet bowl overflow chamber 8 to quickly fill with negative pressure.

The negative pressure port of the negative pressure water valve 2 is communicated with the overflow cavity 8, the negative pressure water valve 2 is opened under the action of negative pressure, the water outlet of the negative pressure water valve 2 instantaneously releases high-pressure water to enter the waterway controller 3, and the waterway controller 3 is opened;

the second flushing port of the waterway controller 3 is opened, and the three high-pressure spray heads 10 start spraying water; the interface valve drain port of the waterway controller 3 is opened, high-pressure water in the interface valve 7 is released through the waterway controller 3, the turnover plate of the interface valve 7 is opened, at the moment of opening, dirt in the toilet bowl is quickly sucked away along with negative pressure, and the dirt is discharged through the internal household sewage drain pipeline connected with the overflow cavity 8;

the negative pressure fan assembly 14 is stopped;

the second water flushing port of the waterway controller 3 is used for water, and three high-pressure spray heads 10 are used for spraying water to flush the inner surface of the toilet liner;

the second flushing port of the waterway controller 3 is disconnected, the first flushing port is communicated with water, the joint at the bottom of the closestool is communicated with water, and the bottom of the liner of the closestool is flushed;

the first flushing port of the waterway controller 3 is disconnected, water is not sprayed at the bottom of the toilet liner, high-pressure water only fills the interface valve 7 through the waterway controller 3, the interface valve 7 is closed again, and the system is restored to the initial state.

When the sewage is discharged, the turnover cover in the turnover plate drainage hair component 8b is opened, and after the sewage is discharged, the turnover cover is automatically closed under the action of magnetic attraction.

Under the condition of extremely low domestic running water pressure, the water pump 4 can be used for pressurizing, and a flowmeter is arranged in the water outlet of the water pump 4. The specific use method is that when the second flushing port of the waterway controller 3 is opened and the three high-pressure spray heads 10 start to spray water, the flowmeter detects the flow of tap water, and when the flow is extremely low, the water pump 4 is started to automatically pressurize the tap water; if the flow is sufficient, the water pump 4 remains on standby and does not start.

When in a power outage condition, the internal battery 15 is available for use by the system in the power outage condition.

When in the condition of power and water outage: the urine cleaning process is that high-pressure water still exists in the energy storage tank 6, the button water valve 1 is pressed down, the water outlet of the button water valve 1 instantly releases the high-pressure water through the energy storage tank 6 to enter the water outlet at the bottom of the waterway controller 3, the waterway controller 3 is triggered to be instantly opened, at the moment, the second flushing port of the waterway controller 3 is opened, but three high-pressure spray heads 10 have no water, so that a toilet can be cleaned; the interface valve drain port of the waterway controller 3 is also opened, high-pressure water in the interface valve 7 is released into the overflow cavity 8 through the interface valve drain port of the waterway controller 3, and the turnover plate of the interface valve 7 is opened.

In the process, the delay process of the waterway controller 3 is the same as that of water and electricity, but the interface valve 7 is not closed due to the lack of high-pressure water, and can be kept normally open, so that the toilet can discharge sewage normally. Until the high pressure water is restored, the system is restored to normal.

The cleaning process of the stool cleaning is as follows: because the interface valve 7 is kept open, the overcurrent cavity 8 cannot keep the negative pressure, the negative pressure fan assembly 14 is started and is not effective, and only the manual flushing can be used when the water is cut off as in the urine cleaning.

In this embodiment, a mechanical and electrical hybrid control manner is adopted, and the electrical control portion may drive the mechanical control portion, and the mechanical control portion may not drive the electrical control portion. The mechanical control part is used for flushing urine and toilet, and is driven by a button water valve 1; the electric appliance control part is used for flushing the toilet, and is driven by an electric button 12. Compared with a vacuum sewage draining system in the prior art, the whole intelligent sewage draining device has the advantages that firstly, the mechanical control part controls the urine flushing in consideration of more times of urine than stool, so that frequent starting of an electric appliance is avoided, and energy is saved; secondly, considering that the urine is easy to clean, the mechanical control part can use little water to flush the urine, so that a large amount of water sources are saved; thirdly, the toilet is flushed by using the electric button 12 to drive, the negative pressure fan assembly is started, negative pressure is utilized for pollution discharge, a large amount of water sources are saved when the toilet is flushed by using the negative pressure, a large amount of water is not needed to be used for flushing the toilet, and a small amount of high-pressure water of the mechanical control part is completely enough to deal with flushing of the toilet. Fourth, the system is a vacuum toilet under the condition of power on and water on, and can be used as a common toilet under the condition of no power on, and the whole system ensures that the toilet is not influenced in use no matter what state.
