[0015] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0016] Due to the lack of laws and regulations on rainwater resource utilization in my country at this stage, as well as some investors' skepticism about the benefits of rainwater resource utilization, the cost of large-scale rainwater resource utilization systems is too high, and it is difficult to see benefits in the short term. Although rainwater resource utilization has a wide audience range and rich utilization functions, the initial investment in rainwater utilization projects is large and the projects are relatively complex. At the same time, due to the low rainfall in some areas, existing technical means cannot be used throughout the country. The utility model provides a household rainwater utilization device that can solve the defects and shortcomings of the existing technology.

[0017] like Figure 1 As shown, an embodiment of the utility model provides a household rainwater utilization device, including a rainwater collecting pot 1, a rainwater holding tank 2 is connected to the bottom of the rainwater collecting pot 1, and a first overflow pipe 3 is connected to the top of the rainwater holding tank 2.

[0018] A first water outlet pipe 4 is connected to the bottom of the rainwater holding tank 2, and a first check valve 5, a second check valve 6 and a third check valve 7 are arranged at intervals on the first water outlet pipe 4. A wash basin 8 is connected to the first water outlet pipe 3 corresponding to the pipe between the second check valve 6 and the third check valve 7, and a second overflow pipe 9 is connected to the end of the first water outlet pipe 3.

[0019] The first water outlet pipe 3 is connected to a second water outlet pipe 10 at a position corresponding to the first check valve 5 and the second check valve 6. A ball switching valve 11 is arranged at the end of the second water outlet pipe 10. A flushing water tank 12 is arranged below the second water outlet pipe 10, and the second water outlet pipe 10 is connected to the inside of the flushing water tank 12. A third water outlet pipe 13 is arranged at the bottom of the flushing water tank 12, and the flushing water tank 12 is also connected to a tap water pipe 14.

[0020] The first outlet pipe 3 has a vertical portion corresponding to the pipe between the second check valve 6 and the third check valve 7, and the wash basin 8 is located at the top of the vertical portion. The first overflow pipe 3 is connected to the rainwater pipe, the second overflow pipe 9 is connected to the wastewater pipe, and the third outlet pipe 13 is connected to the sewage pipe.

[0021] When it rains, rainfall is collected by the rainwater collecting pot 1 and enters the rainwater holding tank 2. At this time, the first check valve 5 is in an open state, and water flows into the flushing water tank 12. The second check valve 6 is in a closed state to prevent rainwater from entering the wash basin 8. After the flushing water tank 12 is filled, rainwater continues to be stored in the rainwater holding tank 2. After the rainwater holding tank 2 is full, it flows out from the first overflow pipe 3.

[0022] When the weather is fine, the washing water enters the flushing water tank 12, at which time the second check valve 6 is opened, the first check valve 5 is closed, and after the flushing water tank 12 is full, the third check valve 7 is opened. The washing water is discharged through the second overflow pipe 9.

[0023] When the water pressure above the spherical switching valve 11 is high, the ball valve moves downward to close the water inlet of the water pipe 14; when the pressure above the ball valve is insufficient, the ball valve moves upward to replenish water through the water pipe 14.

[0024] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
