[0027] The present invention adopts the following technical solution: Example 1: like Figures 1 to 4 As shown, this utility model provides a water-saving toilet flushing storage tank system. The storage tank 1 has an open top, and a transparent top cover 15 is connected to the top via a stepped stop. A partition 11 is fixed inside the storage tank 1, dividing the inner cavity of the storage tank 1 into a sedimentation chamber 13 and a purified water chamber 14. In this embodiment, the partition 11 divides the volume of the sedimentation chamber 13 and the purified water chamber 14 into a 1:3 ratio.

[0028] Combined Figure 5 As shown, a transparent liquid level observation window 16 is installed on the front side of the water storage tank 1, which is opposite to the purified water chamber 14, making it easy to observe the water level in the purified water chamber 14. A pair of hooks 17 are fixed to the rear side of the water storage tank 1 for easy fixation of the water storage tank 1. Two symmetrical lifting handles 152 are fixed on the top cover 15; a water inlet 151 is opened on one side of the top cover 15, which is opposite to the sedimentation chamber 13, making it easy to actively add wastewater from washing or washing machine rinsing directly into the sedimentation chamber 13 through the water inlet 151.

[0029] Combination Figure 3 , Figure 6 and Figure 7 As shown, a filter assembly 12 is installed on the partition 11, and the filter assembly 12 connects the sedimentation chamber 13 and the purified water chamber 14. In this embodiment, the partition 11 has a mounting through hole 111 with a flange; the filter assembly 12 includes a filter cover 121 with a flange as well, and a filter paper 122 is attached to the side of the filter cover 121 near the mounting through hole 111; in use, the filter cover 121 is fastened in the mounting through hole 111 by the flange structure, and the filter paper 122 is pressed onto the mounting through hole 111 of the partition 11.

[0030] Combination Figures 1 to 3As shown, in the water storage tank 1, the bottom of the sedimentation chamber 13 has an internal threaded hole connected to the drain pipe 3, and the other end of the drain pipe 3 is connected to the ground drain pipe 6. The first control valve 31 is installed in the drain pipe 3. The first control valve 31 is used to control water flow and periodically discharge sewage, clean the sedimented impurities, prevent long-term accumulation leading to blockage or odor, and maintain the continuous and efficient operation of the system. The bottom side of the sedimentation chamber 13 has an internal threaded hole connected to the inlet pipe 2. The upper side of the sedimentation chamber 13 has an internal threaded hole connected to the overflow pipe 4. The other end of the overflow pipe 4 is connected to the position behind the first control valve 31 on the drain pipe 3. The upper port of the overflow pipe 4 is higher than the position of the filter assembly 12. When there is excessive wastewater (such as a large amount of drainage in a short period of time), the excess water is directly discharged to the drain pipe through the overflow pipe to avoid the water level in the sedimentation chamber from overflowing the water storage tank. The bottom of the purified water chamber 14 has an internal threaded hole connected to the water supply pipe 5, and the second control valve 51 is installed in the water supply pipe 5.

[0031] Example 2: Based on the above embodiment one, combined with Figures 1 to 3 As shown, in this embodiment, the inlet pipe 2 and the supply pipe 5 are respectively connected to the washbasin 7 and the toilet tank 8. The first supply pipe 71 with the first angle valve 72 supplies water to the washbasin 7, the inlet pipe 2 is connected to the lower part of the washbasin 7, and the toilet tank 8 is suspended below the bottom of the washbasin 7. In use, the water after use in the washbasin 7 flows into the sedimentation chamber 13 of the water storage tank 1 through the inlet pipe 2, and enters the clean water chamber 14 after being filtered by the sedimentation and filtration components 12.

[0032] A second water supply pipe 81 with a second angle valve 82 supplies water to the toilet tank 8. Simultaneously, a water supply pipe 5 connects to the rear of the second angle valve 82 on the second water supply pipe 81. In use, the second angle valve 82 is closed, and the second control valve 51 is opened. Water stored in the purified water chamber 14 enters the toilet tank 8 through the water supply pipe 5 and the second water supply pipe 81, achieving secondary reuse of washing wastewater. This embodiment achieves the utilization of wastewater from the washbasin without altering the water control system within the toilet tank. Furthermore, based on specific actual usage needs and referring to the above principle, the inlet pipe 2 and the water supply pipe 5 can also be connected to other products.
