A water saving method of a building roof water saving system comprises the following steps:
s1, rainwater collection: part of the rainwater permeates the green planting layer 5 and then flows into the water collecting channel 4 through the grid plate; part of the rainwater flows into the water collecting channel 4 through the drainage channel 6 and is converged.
S2, filtering the converged rainwater by the warm stone layer 3 and the activated carbon layer 2, flowing into a first filter box, filtering by the first filter plate 18, flowing into a second filter box, reversely filtering by the second filter plate 17, and flowing into a third filter box; whether the water in the third filter tank flows into the steam fog tank 12 or not is determined by the water level in the steam fog tank 12:

The first ultrasonic oscillation sheet 13 atomizes the water vapor in the vapor box 12, which is substantially the final filtering process.
The water in the water storage tank 9 is in a steam fog shape through the second ultrasonic oscillation sheet, one part of steam fog is condensed into liquid drops by the condensation cone 10 and is converged into the water storage tank 9, and the other part of steam fog flows into the water collecting channel 4 through the steam fog branch pipe 8;
part of the steam fog flowing into the water collecting channel 4 rises to infiltrate the green plant layer 5 through the grid plate, and the other part of the steam fog sinks to be in contact with the warm stone layer 3 and/or the activated carbon layer 2 and is condensed into water drops;
s4, when the water level in the water storage tank 9 is higher than the critical water level of the third floating ball 27 valve, the toilet flushing pipe 11 is connected, water overflows into the toilet flushing pipe 11, the reversing valve 25 is connected with the toilet flushing pipe 11 according to the water pressure, and if the water pressure is insufficient, the reversing valve 25 is connected with the water purifying pipe 23;

Namely, when the rainwater is sufficient, the toilet flushing device can be used for flushing toilets on all floors, and the using amount of purified water is reduced; when the rainwater is insufficient or a certain amount of rainwater is used, the residual water preferentially ensures the water consumption of the green plant layer 5.
When the water level in the water storage tank 9 is lower than the critical water level of the second ball float valve 19, a municipal water supply pipe is connected to supplement water into the water storage tank 9;
when the water level in the tank 9 is above the critical level of the second float valve 19 the municipal water supply pipe is closed. That is, when the remaining water is not enough to ensure the water usage of the green plant layer 5, the water supply is complemented by the municipal water supply pipe, ensuring the growth of the green plants, and at the same time, the municipal water supply is not used for flushing the toilet.
Preferably, the reversing valve 25 is reversed according to the water pressure, and when the sewage pressure (based on the height of water in the toilet flushing pipe 11 of the reversing valve 25 and the valve plate force) is less than the hydrostatic pressure, namely when the sewage quantity is insufficient, the water is supplied by the water purifying pipe 23; on the contrary, when the sewage quantity is sufficient, the toilet flushing pipe 11 is filled with water, the sewage pressure and valve plate force are greater than the hydrostatic pressure, and the toilet flushing pipe 11 supplies water. Therefore, when the second ball float valve 19 is closed and some water is still stored in the toilet flushing pipe 11, the toilet flushing water of each floor is changed from top to bottom according to the height of the stored water.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.

9. The water saving system for the roof of the building as claimed in claim 2, wherein the first ball valve comprises a first valve pipe, a first valve ball supported by a first spring is arranged in the first valve pipe, and a first valve line connects the first valve ball and a second ball float arranged in the aerosol tank;
the first valve ball is opened and closed by the pulling force of the first floating ball and is connected with a connecting port of the third filter water tank.
10. A method of saving water in a roof water saving system of a building as claimed in any one of claims 1 to 9, comprising the steps of:
s1, rainwater collection: part of rainwater permeates the green planting layer and flows into the water collecting channel through the grid plate; part of the rainwater flows into the water collecting channel through the drainage channel and is converged;
s2, filtering the converged rainwater through a warm stone layer and/or an activated carbon layer, flowing into a first filter box, filtering through a first filter plate, flowing into a second filter box, reversely filtering through a second filter plate, and flowing into a third filter box; whether the water in the third filter tank flows into the steam fog tank is determined by the water level in the steam fog tank:
namely: when the water level in the steam fog tank is higher, the first float valve is closed; when the water level in the steam fog tank is lower, the first ball float valve is opened, and water in the third filter tank is supplemented into the steam fog tank;
s3, making the water in the steam fog box into steam fog shape by the first ultrasonic oscillation piece, flowing into the water storage tank, condensing a part of steam fog into liquid drops by the condensation cone, converging the liquid drops into the water storage tank, flowing the other part of steam fog into the water collecting channel by the steam fog branch pipe,
the water in the water storage tank is in a steam fog shape through the second ultrasonic oscillation sheet, one part of steam fog is condensed into liquid drops by the condensation cone and is converged into the water storage tank, and the other part of steam fog flows into the water collecting channel through the steam fog branch pipe;
part of the steam fog flowing into the water collecting channel rises to infiltrate the green plant layer through the grid plate, and the other part of the steam fog sinks to be contacted with the warm stone layer and/or the activated carbon layer and is condensed into water drops;
s4, when the water level in the water storage tank is higher than the critical water level of the third ball float valve, the toilet flushing pipe is connected, water overflows into the toilet flushing pipe, the reversing valve is connected with the toilet flushing pipe according to the water pressure, and if the water pressure is insufficient, the reversing valve is connected with the water purifying pipe;
when the water level in the water storage tank is lower than the critical water level of the third ball float valve, the toilet flushing pipe is closed;
when the water level in the water storage tank is lower than the critical water level of the second ball float valve, a municipal water supply pipe is connected to supplement water into the water storage tank;
when the water level in the storage water tank is higher than the critical water level of the second ball float valve, the municipal water supply pipe is closed.
